Description

Technical Field

[0001] This application relates to the field of manufacturing technology, and more specifically, to a feeding device and a feeding method for sheet materials. Background Technology

[0002] In recent years, with the rapid development of industrial automation, most existing manufacturing production lines have adopted automated production lines to reduce labor costs and improve production efficiency. Among these, sheet materials are typically lightweight and thin, such as heat insulation pads, insulating pads, electrode sheets, or current collectors in batteries. During the assembly of sheet materials, automated loading is difficult and has low compatibility; currently, manual loading is commonly used. This results in high labor intensity and low efficiency during the assembly process, hindering efforts to improve loading efficiency and reduce assembly costs. Summary of the Invention

[0003] This application provides a feeding device and a feeding method for sheet materials, which can effectively reduce the cost of automated assembly of sheet materials and improve the compatibility of automated feeding of sheet materials.

[0004] In a first aspect, embodiments of this application provide a feeding device, including a frame, a feeding mechanism, a lifting mechanism, a loading mechanism, and a detection unit; the feeding mechanism is disposed on the frame, and the feeding mechanism includes a hopper for holding multiple stacked sheets; the lifting mechanism is disposed on the frame, and the lifting mechanism includes a lifting member configured to lift the sheets in the hopper; the loading mechanism includes a picking unit and an actuating member, the picking unit includes an adsorption member, the picking unit is connected to the actuating member, and the actuating member is configured to drive the picking unit to move so that the adsorption member picks up the sheets; the detection unit is used to detect the adsorption pressure of the adsorption member adsorbing the sheets, and the lifting member is configured to stop lifting the sheets when the adsorption pressure reaches a preset value.

[0005] In the above technical solution, the lifting mechanism can lift multiple sheets in the hopper, allowing the uppermost sheet to abut against the adsorption component of the pickup unit. The adsorption component then picks up the sheet. A detection unit monitors the adsorption pressure on the sheet, and when the pressure reaches a preset value, the lifting mechanism stops lifting the sheet, keeping it stationary. This facilitates the transfer of the picked-up sheet to the next material, improving feeding efficiency. This feeding equipment eliminates the need for complex lifting position programming and high precision requirements for the lifting mechanism. The requirement is that the lifting position of the lifting component can be controlled simply by judging whether the lifting component stops lifting based on the adsorption pressure of the adsorption component. This enables automated feeding of sheet materials, thereby improving the accuracy of the adsorption component in picking up the sheet materials and reducing the phenomenon of sheet materials not being picked up due to positional differences between the adsorption component and the sheet materials. It can also effectively reduce the manufacturing cost and programming cost of the lifting mechanism, thereby reducing the cost of automated assembly of sheet materials. On the other hand, when lifting and feeding sheet materials of different thicknesses, there is no need to replace the lifting component or reprogram the lifting position of the lifting component. This helps to improve the applicability and production flexibility of the feeding equipment, making the feeding equipment highly compatible.

[0006] In some embodiments, the feeding mechanism further includes a movable frame and a first driving member; the movable frame is movably disposed on the frame along a first direction, the hopper is mounted on the movable frame, the movable frame has a loading position for placing the sheet material into the hopper and a dispensing position for the lifting member to lift the sheet material in the hopper in the first direction, the first direction being perpendicular to the lifting direction of the lifting member; the first driving member is connected to the frame and the movable frame, and the first driving member is configured to drive the movable frame to switch between the loading position and the dispensing position.

[0007] In the above technical solution, the feeding mechanism is also equipped with a movable frame and a first driving component. The first driving component can drive the movable frame to move relative to the machine frame in a first direction, so as to realize the movement of the movable frame between the loading position and the picking position. This can drive the hopper set on the movable frame to switch between the loading position and the picking position. On the one hand, it is convenient to load the hopper, so that the position for loading the hopper is far away from the position for the feeding mechanism to pick up the sheet material. This helps to alleviate the interference phenomenon when loading and picking up the sheet material, thereby reducing the safety hazards in the production process. On the other hand, the assembly of the sheet material and subsequent feeding can be realized without manual handling of the sheet material to the picking position of the movable frame, which helps to reduce the intensity of manual labor and save labor costs.

[0008] In some embodiments, the feeding device includes two feeding mechanisms, and the movable frames of the two feeding mechanisms are arranged at intervals along the lifting direction of the lifting member.

[0009] In the above technical solution, the feeding equipment is equipped with two feeding mechanisms arranged at intervals along the lifting direction of the lifting component. This allows the movable frame of one feeding mechanism to be in the loading position for loading, while the movable frame of the other feeding mechanism is in the picking position for the feeding mechanism to pick up and feed the sheet material. This enables the two feeding mechanisms to work together and switch between each other, thereby achieving non-stop loading and feeding of the feeding equipment. This ensures continuous operation of the feeding equipment and improves the operating rate of the feeding equipment, thus increasing the production efficiency of the sheet material.

[0010] In some embodiments, the lifting mechanism further includes an adjustment component; the adjustment component is connected to the frame and the lifting member, and the adjustment component is configured to adjust the height position of the lifting member in the lifting direction of the lifting member, so that the lifting member switches between a first lifting position and a second lifting position; the lifting member is configured to: lift the sheet material in the hopper of one of the feeding mechanisms when it is in the first lifting position, and lift the sheet material in the hopper of another feeding mechanism when it is in the second lifting position.

[0011] In the above technical solution, the lifting mechanism is also provided with an adjustment component for adjusting the height position of the lifting member. The adjustment component can drive the lifting member to move in the lifting direction of the lifting member, so that the lifting member can switch between the first lifting position and the second lifting position. This allows the lifting member to lift the sheet material in the hopper of different feeding mechanisms when it is in different positions. This makes it possible for the lifting member of the lifting mechanism to lift the sheet material in the hopper of two feeding mechanisms, without having to set the size and lifting stroke of the lifting member in the lifting direction to meet the needs of two feeding mechanisms. This helps to reduce the assembly difficulty and manufacturing cost of the lifting mechanism.

[0012] In some embodiments, the adjustment assembly includes a mounting base and a second drive member; the mounting base is movably disposed on the frame along the lifting direction of the lifting member, and the lifting member is mounted on the mounting base; the second drive member is connected to the mounting base and is configured to drive the mounting base to move along the lifting direction of the lifting member, thereby causing the lifting member to switch between a first lifting position and a second lifting position.

[0013] In the above technical solution, the adjustment component is provided with a mounting base and a second driving component. The lifting component is set on the mounting base, so that the second driving component can drive the mounting base to move in the lifting direction of the lifting component, thereby driving the lifting component to switch between the first lifting position and the second lifting position. In this way, the lifting component can lift the sheet material in the hopper of the two feeding mechanisms. This structure is simple, easy to implement, and conducive to improving the automation level of the feeding equipment.

[0014] In some embodiments, the adjustment assembly further includes a base and a guide rod; the base is connected to the frame, and the base is provided with a guide hole extending along the lifting direction of the lifting member, and the second drive member is mounted on the base; the guide rod is movably inserted into the guide hole along the lifting direction of the lifting member, and the guide rod is connected to the mounting base.

[0015] In the above technical solution, the adjustment component is also provided with a base and a guide rod. By providing a guide hole on the base and movably inserting the guide rod into the guide hole along the lifting direction of the lifting member, the guide rod can guide the mounting base when the second driving member drives the mounting base to move along the lifting direction of the lifting member, thereby improving the stability of the mounting base when it moves along the lifting direction of the lifting member.

[0016] In some embodiments, the lifting mechanism further includes a first detection element, which is mounted on the lifting member and is configured to correspond one-to-one with the lifting member; the first detection element is configured to detect the sheet material in the hopper and generate a first signal indicating that there is no sheet material in the hopper, and the lifting member is configured to reset and disengage from the hopper according to the first signal.

[0017] In the above technical solution, the lifting mechanism is also equipped with a first detection element, which is installed on the lifting component. The first detection element can detect whether there are still pieces of material in the hopper, so that when there are no pieces of material in the hopper, the lifting component can respond to the first detection element, exit from the hopper and reset. This facilitates the first drive component to drive the moving component to switch between the loading position and the unloading position, thereby reducing the interference of the lifting component on the hopper. Moreover, no manual intervention is required, which helps to improve the automation level of the feeding equipment and improve production efficiency.

[0018] In some embodiments, the lifting mechanism further includes a second detection element, which is mounted on the lifting member and is configured to correspond one-to-one with the lifting member. The second detection element is configured to detect the reset state of the lifting member and generate a second signal characterizing the reset of the lifting member. The adjustment component is configured to adjust the height position of the lifting member in the lifting direction of the lifting member according to the second signal, and the first drive component is configured to drive the movable frame to switch between the loading position and the unloading position according to the second signal.

[0019] In the above technical solution, the lifting mechanism is also equipped with a second detection element, which is installed on the lifting component. The second detection element can detect the reset state of the lifting component, so that the adjustment component of the lifting mechanism responds to the second detection element and drives the lifting component to switch between the first lifting position and the second lifting position. The first drive component responds to the second detection element and drives the movable frame to switch between the loading position and the unloading position. This enables the feeding equipment to switch between the two feeding mechanisms without stopping the machine, without manual intervention, which helps to improve the automation level of the feeding equipment and improve production efficiency.

[0020] In some embodiments, the feeding mechanism includes a plurality of hoppers, all of which are mounted on the movable frame, and the hoppers are configured in a one-to-one correspondence with the lifting components.

[0021] In the above technical solution, by setting multiple material bins on the movable frame of the feeding mechanism, and setting the lifting component of the lifting mechanism in a one-to-one correspondence with the material bins of each feeding mechanism, the feeding mechanism can move the sheet materials placed in multiple material bins to the picking position for feeding, which is conducive to optimizing the production cycle of the feeding equipment and improving the production efficiency of the feeding equipment.

[0022] In some embodiments, the lifting member includes a self-locking cylinder configured to self-lock when the adsorption pressure of the adsorption member reaches a preset value, so as to stop lifting the sheet material.

[0023] In the above technical solution, the lifting component is equipped with a self-locking cylinder, which can lift the sheet material in the hopper. The self-locking cylinder can also self-lock in response to the detection unit when the adsorption pressure of the adsorption component reaches a preset value, so that the lifting component stops lifting the sheet material. This type of lifting component has a simple structure, is easy to implement, and has high stability in use. On the other hand, the self-locking of the self-locking cylinder can keep the sheet material in its original position, thereby improving the stability and reliability of the adsorption component of the pickup unit in adsorbing and picking up the sheet material.

[0024] In some embodiments, the hopper includes a base and a plurality of limiting members; the base is used to place the sheet material, and the base is provided with a lifting hole through which the lifting member passes along the lifting direction of the lifting member; the plurality of limiting members are disposed on the base and arranged at intervals around the lifting hole.

[0025] In the above technical solution, the hopper is equipped with a base and multiple limiting components. A lifting hole is provided on the base for the lifting component to pass through, allowing it to enter the hopper and lift the sheet material. The structure is simple and easy to implement. Furthermore, by setting multiple limiting components on the base, and having these components spaced around the lifting hole (i.e., spaced circumferentially along the lifting hole), the multiple limiting components can limit and guide the sheet material placed on the base, reducing the possibility of sheet material falling off or deviating during lifting, thus facilitating the normal operation of the feeding equipment.

[0026] In some embodiments, the plurality of limiting members include a first limiting member and a second limiting member. Along a first direction, the first limiting member is provided on both sides of the lifting hole, and along a second direction, the second limiting member is provided on both sides of the lifting hole. The first direction, the second direction, and the lifting direction of the lifting member are perpendicular to each other.

[0027] In the above technical solution, the multiple limiting components include a first limiting component located on both sides of the lifting hole in the first direction and a second limiting component located on both sides of the lifting hole in the second direction. This allows the multiple limiting components to limit the sheet material on both sides in the first and second directions, thereby further improving the limiting and guiding effect of the multiple limiting components on the sheet material, and further alleviating the phenomenon of sheet material falling off or deviating when the lifting component lifts the sheet material.

[0028] In some embodiments, the first limiting member located on at least one side of the lifting hole is adjustablely positioned on the base along the first direction; and / or, the second limiting member located on at least one side of the lifting hole is adjustablely positioned on the base along the second direction.

[0029] In the above technical solution, by setting the first limiting member located on at least one side of the lifting hole in the first direction to be adjustablely positioned on the base along the first direction, the limiting width of multiple first limiting members on the sheet material in the first direction can be adjusted by adjusting the position of the first limiting member in the first direction. This is suitable for sheet materials of different sizes in the first direction, thereby enabling the hopper to store sheet materials of different sizes, which improves the applicability of the hopper and enhances the production flexibility of the feeding equipment. Similarly, by setting the second limiting member located on at least one side of the lifting hole in the second direction to be adjustablely positioned on the base along the second direction, the limiting width of multiple second limiting members on the sheet material in the second direction can be adjusted by adjusting the position of the second limiting member in the second direction. This is suitable for sheet materials of different sizes in the second direction, thereby enabling the hopper to store sheet materials of different sizes, which improves the applicability of the hopper and enhances the production flexibility of the feeding equipment.

[0030] In some embodiments, the base is provided with a first adjustment groove, the first adjustment groove extends along the first direction, and a portion of the first limiting member is movably inserted into the first adjustment groove along the first direction.

[0031] In the above technical solution, by setting a first adjustment groove extending along a first direction on the base, and partially inserting the first limiting member into the first adjustment groove along the first direction, the position of the first limiting member in the first direction can be adjusted. The hopper with this structure can realize continuous multi-level adjustment of the position of the first limiting member in the first direction to meet the placement requirements of sheet materials of different sizes, thereby further improving the applicability of the hopper.

[0032] In some embodiments, the base is provided with a second adjustment groove, the second adjustment groove extends along the second direction, and a portion of the second limiting member is movably inserted into the second adjustment groove along the second direction.

[0033] In the above technical solution, by setting a second adjustment groove extending along the second direction on the base, and partially inserting the second limiting member into the second adjustment groove along the second direction, the position of the second limiting member in the second direction can be adjusted. The hopper with this structure can realize continuous multi-level adjustment of the position of the second limiting member in the second direction to meet the placement requirements of sheet materials of different sizes, thereby further improving the applicability of the hopper.

[0034] In some embodiments, the hopper further includes a first separating component and a second separating component, at least one of the first limiting components is provided with the first separating component, at least one of the first limiting components is provided with the second separating component, the first separating component is located above the second separating component along the lifting direction of the lifting component, and both the first separating component and the second separating component are configured to separate two stacked sheets during the process of the feeding mechanism picking up the sheets in the hopper.

[0035] In the above technical solution, the hopper is also provided with a first material separating component and a second material separating component. The first material separating component is positioned above the second material separating component in the lifting direction of the lifting component. Thus, when the feeding mechanism picks up the sheet material in the hopper, the first and second material separating components can separate the sheet material twice to improve the separation effect of the sheet material stacked on top of each other. This can effectively alleviate the phenomenon of material being carried along when the feeding mechanism picks up the sheet material, so as to realize the single picking of sheet material.

[0036] In some embodiments, the first material separating component and the second material separating component are respectively disposed on the two first limiting components.

[0037] In the above technical solution, by setting the first part and the second part on different first limiting parts, it is convenient to assemble the first part and the second part, which helps to reduce the assembly difficulty and effectively alleviates the interference between the first part and the second part.

[0038] In some embodiments, along the first direction, at least one set of two oppositely arranged first limiting members are each provided with a first distributing member, and the two first distributing members are oppositely arranged; at least one set of two oppositely arranged first limiting members are each provided with a second distributing member, and the two second distributing members are oppositely arranged.

[0039] In the above technical solution, each of the first limiting members arranged opposite to each other in the first direction is provided with a first separating member, and the two first separating members are arranged opposite to each other. Correspondingly, each of the first limiting members arranged opposite to each other in the first direction is provided with a second separating member, and the two second separating members are arranged opposite to each other. Thus, the two first separating members and the two second separating members arranged opposite to each other can improve the separation effect of the sheet material, so as to further alleviate the phenomenon of material carrying when the feeding mechanism picks up the sheet material, and ensure the single picking of the sheet material.

[0040] In some embodiments, along the first direction, the distance between two oppositely arranged first material distribution components is less than the distance between two oppositely arranged second material distribution components.

[0041] In the above technical solution, by setting the distance between the two first separating components in the first direction to be smaller than the distance between the second separating components in the first direction, the first separating components and the second separating components exert different force on the sheet material. This allows the two second separating components located below the first separating components to perform preliminary separation of the sheet material first, and then the two first separating components located above the second separating components to further separate the sheet material. This is beneficial to improving the separation effect of the two stacked sheet materials, so as to achieve single picking of the sheet material.

[0042] In some embodiments, both the first and second separating components are brushes, and the hardness of the bristles of the first separating component is less than the hardness of the bristles of the second separating component.

[0043] In the above technical solution, both the first and second separating components are brushes, which have a simple structure and facilitate the separation of sheet materials. Furthermore, by setting the hardness of the bristles of the first separating component to be less than that of the bristles of the second separating component, damage to the sheet materials caused by the two first separating components located above the second separating component and with a small distance between them is reduced, and the sheet material separating effect of the two first separating components is improved.

[0044] In some embodiments, the pickup unit further includes a connecting seat; the connecting seat is connected to the actuator, and the connecting seat is provided with at least one set of adsorption elements, each set of adsorption elements including multiple adsorption elements, and each set of adsorption elements adsorbs one piece of the sheet material in the hopper.

[0045] In the above technical solution, the picking unit is provided with a connecting seat connected to the actuator, and the adsorption element is disposed on the connecting seat, so that the actuator can drive the adsorption element to move and adsorb and pick up the sheet material in the hopper. In addition, the connecting seat is provided with at least one set of adsorption elements, and each set of adsorption elements includes multiple adsorption elements, so that multiple adsorption elements can cooperate to adsorb the sheet material in a hopper, which helps to improve the picking stability of the picking unit in picking up the sheet material, thereby reducing the risk of the sheet material falling off during the transfer and loading process.

[0046] In some embodiments, each set of adsorption elements includes three non-collinear adsorption elements, and at least one of the three adsorption elements is adjustablely positioned on the connecting seat along a direction perpendicular to the lifting direction of the lifting element.

[0047] In the above technical solution, each set of adsorption elements on the connecting seat of the pickup unit includes three non-collinear adsorption elements, meaning that the three adsorption elements collectively define a plane, which helps to further improve the adsorption stability and reliability of each set of adsorption elements for the sheet material. Furthermore, by setting at least one of the three adsorption elements to be positionably mounted on the connecting seat, the distance between the three adsorption elements can be adjusted to meet the pickup needs of sheet materials of different sizes, thus expanding the applicability of the pickup unit and effectively improving the production flexibility of the feeding equipment.

[0048] In some embodiments, the three adsorption elements include a first adsorption element, a second adsorption element, and a third adsorption element; the first adsorption element is fixedly connected to the connecting seat; the second adsorption element is spaced apart from the first adsorption element along a first direction, and the second adsorption element is adjustablely positioned on the connecting seat along the first direction; the third adsorption element is spaced apart from both the first and second adsorption elements along a second direction, and the third adsorption element is adjustablely positioned on the connecting seat along the second direction, wherein the first direction, the second direction, and the lifting direction of the lifting element are perpendicular to each other.

[0049] In the above technical solution, each set of adsorption components includes a first adsorption component fixedly connected to the connecting seat, a second adsorption component whose position is adjustable along the first direction, and a third adsorption component whose position is adjustable along the second direction. By adjusting the position of the second adsorption component in the first direction and adjusting the position of the third adsorption component in the second direction, the spacing between the three adsorption components in each set of adsorption components in the first and second directions can be adjusted to adapt to sheet materials of different sizes in the first and second directions, thereby further improving the applicability of the picking unit.

[0050] In some embodiments, the connector is provided with multiple sets of adsorption elements.

[0051] In the above technical solution, by setting multiple sets of adsorption components on the connecting seat, the picking unit can simultaneously pick up the sheet material in multiple hoppers, so as to feed multiple sheet materials at the same time, which is conducive to optimizing the production cycle of the feeding equipment and improving the production efficiency of the feeding equipment.

[0052] Secondly, this application also provides a method for feeding sheet material, applicable to the above-mentioned feeding equipment. The method for feeding sheet material includes: driving the picking unit to move above the sheet material via the actuator; lifting the sheet material in the hopper via the lifting member so that the sheet material abuts against the adsorption member; when the adsorption pressure of the adsorption member adsorbing the sheet material reaches a preset value, the lifting member stops lifting the sheet material; and transferring the sheet material adsorbed by the adsorption member to the feeding position via the actuator to feed the sheet material.

[0053] In the above technical solution, the sheet material feeding method involves first moving the pickup unit to above the sheet material in the hopper via an actuator, then lifting the sheet material by a lifting component, so that the uppermost sheet material can abut against the adsorption component, allowing the adsorption component to adsorb the sheet material. When the adsorption pressure of the adsorption component reaches a preset value, the lifting component stops lifting the sheet material. After the adsorption component has adsorbed the sheet material, the actuator can move the pickup unit to feed the sheet material. This feeding method eliminates the need for complex lifting position programming and high precision requirements for the lifting component of the lifting mechanism. According to the requirements, the lifting position control of the lifting component can be achieved simply by judging whether to stop based on the adsorption pressure of the adsorption component. This improves the accuracy of the adsorption component in picking up the sheet material, reducing the phenomenon of sheet material not being picked up due to positional differences between the adsorption component and the sheet material. It can also effectively reduce the manufacturing cost and programming cost of the lifting mechanism. On the other hand, when lifting and feeding sheet materials of different thicknesses, there is no need to replace the lifting component or reprogram the lifting position of the lifting component. This helps to improve the applicability and production flexibility of the feeding equipment, making the feeding equipment highly compatible.

[0054] In some embodiments, before the sheet material in the hopper is lifted by the lifting member to bring the sheet material against the adsorption member, the sheet material feeding method further includes: opening the adsorption member to allow the adsorption member to draw in air.

[0055] In the above technical solution, the adsorption component is opened before the lifting component lifts the sheet material to allow the adsorption component to draw in air. This allows the adsorption component to adsorb the sheet material when the lifting component lifts it to the point where it comes into contact with the adsorption component. This allows the adsorption component to adsorb the sheet material at the same time as the lifting component lifts it, thereby reducing the lifting stroke of the lifting component on the sheet material and reducing the difficulty of program control of the feeding equipment.

For example, in automated battery production lines, sheet materials such as heat insulation pads, insulating pads, electrode sheets, or connectors are loaded and assembled. Since these sheet materials have a thin, sheet-like structure, they are typically stacked in groups during storage or transport. Therefore, during the loading and assembly process, a single sheet needs to be picked from the stacked sheets for individual loading to facilitate subsequent manufacturing or assembly.

[0084] The inventors discovered that automating the feeding of sheet metal is quite difficult, and currently, manual feeding is commonly used. This results in high labor intensity and low efficiency during the assembly process, hindering improvements in sheet metal feeding efficiency and assembly costs. To improve sheet metal feeding efficiency and reduce manufacturing costs, a hopper for storing multiple sheet metals is typically installed. A lifting mechanism lifts the sheet metal in the hopper, raising the top sheet to a designated position. A gripper then picks up the sheet metal at the designated position, thus achieving automated sheet metal feeding. However, in this type of sheet material feeding production line, on the one hand, it is necessary to set multiple complex position programming points for the lifting mechanism and to manufacture the lifting mechanism with high precision in order to improve the accuracy of the gripper in picking up the sheet material, resulting in high sheet material feeding and assembly costs. On the other hand, when changing to different types of sheet material for feeding and assembly, such as changing to sheet material of different thicknesses, it is necessary to reset multiple position programming points for the lifting process of the lifting mechanism, resulting in poor compatibility of automated sheet material feeding and hindering the improvement of production flexibility for automated sheet material feeding and assembly.

[0085] Based on the above considerations, and to address the issues of high cost and low compatibility in automated sheet material feeding, the inventors, after in-depth research, designed a feeding device. The feeding device includes a frame, a feeding mechanism, a lifting mechanism, and a detection unit. The feeding mechanism is mounted on the frame and includes a hopper for holding multiple stacked sheets. The lifting mechanism is also mounted on the frame and includes a lifting element configured to lift the sheets from the hopper. The feeding mechanism includes a pickup unit and an actuator. The pickup unit includes an adsorption element connected to the actuator, which is configured to move the pickup unit to allow the adsorption element to pick up the sheets. The detection unit detects the adsorption pressure of the adsorption element on the sheets, and the lifting mechanism is configured to stop lifting the sheets when the adsorption pressure reaches a preset value.

[0086] In this type of feeding equipment, the lifting mechanism can lift multiple sheets in the hopper, allowing the uppermost sheet to abut against the suction unit. The suction unit then picks up the sheet. A detection unit monitors the suction pressure on the sheet, and when the pressure reaches a preset value, the lifting mechanism stops lifting the sheet, keeping it stationary. This facilitates the transfer of the sheet after pickup, improving feeding efficiency. This feeding equipment eliminates the need for complex lifting position programming and high precision requirements for the lifting mechanism. According to the requirements, the lifting position of the lifting component can be controlled simply by judging whether the lifting component stops lifting based on the adsorption pressure of the adsorption component. This enables automated feeding of sheet materials, thereby improving the accuracy of the adsorption component in picking up the sheet materials and reducing the phenomenon of sheet materials not being picked up due to positional differences between the adsorption component and the sheet materials. It can also effectively reduce the manufacturing cost and programming cost of the lifting mechanism, thereby reducing the cost of automated assembly of sheet materials. On the other hand, when lifting and feeding sheet materials of different thicknesses, there is no need to replace the lifting component or reprogram the lifting position of the lifting component. This helps to improve the applicability and production flexibility of the feeding equipment, making the feeding equipment highly compatible.

[0087] This application provides a feeding device that can improve the problem that the automated feeding of sheet materials in the production line requires complex programming and reprogramming after changing to sheet materials of different thicknesses, resulting in high cost and low compatibility of automated sheet material feeding. The specific structure of the feeding device is described in detail below with reference to the accompanying drawings.

[0088] According to some embodiments of this application, please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic block diagram of a feeding device 100 provided in some embodiments of this application. Figure 2 This is a schematic diagram of the structure of the feeding device 100 provided in some embodiments of this application. Figure 3This is a front view of a feeding device 100 provided in some embodiments of this application. Embodiments of this application provide a feeding device 100, which includes a frame 10, a feeding mechanism 20, a lifting mechanism 30, a feeding mechanism 40, and a detection unit 50. The feeding mechanism 20 is disposed on the frame 10 and includes a hopper 21 for holding multiple stacked sheets 60. The lifting mechanism 30 is disposed on the frame 10 and includes a lifting member 31 configured to lift the sheets 60 within the hopper 21. The feeding mechanism 40 includes a picking unit 41 and an actuator 42. The picking unit 41 includes an adsorption member 411, which is connected to the actuator 42. The actuator 42 is configured to drive the picking unit 41 to move, so that the adsorption member 411 picks up the sheets 60. The detection unit 50 is used to detect the adsorption pressure of the adsorption sheet 60 by the adsorption member 411, and the lifting member 31 is configured to stop lifting the sheet 60 when the adsorption pressure reaches a preset value.

[0089] The hopper 21 serves to hold multiple stacked sheet materials 60. In other words, multiple sheet materials 60 are stacked in the hopper 21 along their thickness direction so that the feeding mechanism 40 can pick up the sheet materials 60.

[0090] The lifting component 31 serves to lift the sheet material 60 within the hopper 21. The lifting component 31 can have various structures, such as an electric push rod or a cylinder. Alternatively, it can be a combination of a motor and a worm gear structure, or a combination of a motor and a rack and pinion structure. It should be noted that the lifting direction X of the lifting component is consistent with the thickness direction of the sheet material 60. The lifting direction X can be vertical or approximately vertical; that is, the lifting direction X can be at an angle to the vertical direction.

[0091] The picking unit 41 is equipped with an adsorption element 411, which adsorbs the sheet material 60 to enable the picking unit 41 to grasp the sheet material 60. The adsorption element 411 can be a suction cup or the like.

[0092] The actuator 42 drives the picking unit 41 to move, thereby picking up and loading the sheet material 60. The actuator 42 can be a three-axis gantry, a four-axis robot, or a six-axis robot. For example, in... Figure 2 In the middle, the actuator 42 is a six-axis robot.

[0093] The detection unit 50 is installed on the picking unit 41 of the feeding mechanism 40. The detection unit 50 is used to detect the adsorption pressure of the adsorption member 411 on the sheet material 60. That is, the detection unit 50 can detect the adsorption negative pressure of the adsorption member 411 so that the lifting member 31 of the lifting mechanism 30 can respond to the detection result of the detection unit 50. For example, the detection unit 50 can be a pressure sensor, etc.

[0094] The lifting member 31 is configured to stop lifting the sheet material 60 when the adsorption pressure reaches a preset value. That is, when the lifting member 31 lifts the sheet material 60 to abut against the adsorption member 411, the adsorption member 411 can adsorb the sheet material 60. At this time, the lifting member 31 can continuously lift the sheet material 60. When the detection unit 50 detects that the adsorption pressure of the adsorption member 411 on the sheet material 60 reaches the preset value, the lifting member 31 can respond to the detection unit 50 and stop lifting the sheet material 60 to complete the pickup unit 41's pickup of the sheet material 60.

[0095] The lifting mechanism 30, via its lifting member 31, can lift multiple sheet materials 60 within the hopper 21, allowing the uppermost sheet material 60 to abut against the adsorption member 411 of the pickup unit 41. This allows the adsorption member 411 to pick up the sheet material 60. The detection unit 50 detects the adsorption pressure of the adsorption member 411 on the sheet material 60. When the adsorption pressure reaches a preset value, the lifting member 31 of the lifting mechanism 30 responds to the detection unit 50 and stops lifting the sheet material 60, keeping it stationary. This facilitates the transfer and feeding of the sheet material 60 after pickup by the adsorption member 411, improving the feeding efficiency. This feeding device 100 with this structure eliminates the need for complex lifting position programming for the lifting member 31 of the lifting mechanism 30. For applications requiring high precision, the lifting position of the lifting component 31 can be controlled simply by judging whether the lifting component 31 has stopped lifting based on the adsorption pressure of the adsorption component 411. This enables automated feeding of the sheet material 60, thereby improving the accuracy of the adsorption component 411 in picking up the sheet material 60. This reduces the occurrence of sheet material 60 not being picked up due to positional differences between the adsorption component 411 and the sheet material 60. It also effectively reduces the manufacturing cost and programming cost of the lifting mechanism 30, thereby reducing the automated assembly cost of the sheet material 60. Furthermore, when lifting and feeding sheet material 60 of different thicknesses, there is no need to replace the lifting component 31 or reprogram the lifting position of the lifting component 31. This improves the applicability and production flexibility of the feeding equipment 100, making the feeding equipment 100 highly compatible.

[0096] According to some embodiments of this application, refer to Figure 2 and Figure 3 Please refer to further details. Figure 4 and Figure 5 , Figure 4 This is a partial structural schematic diagram of the feeding device 100 provided in some embodiments of this application. Figure 5 This is a front view of a partial structure of a feeding device 100 provided in some embodiments of this application. The feeding mechanism 20 also includes a movable frame 22 and a first drive member 23. The movable frame 22 is movably disposed on the frame 10 along a first direction Y. A hopper 21 is mounted on the movable frame 22. The movable frame 22 has a loading position M for placing sheet material 60 into the hopper 21 and a dispensing position N for the lifting member 31 to lift the sheet material 60 from the hopper 21 in the first direction Y. The first direction Y is perpendicular to the lifting direction X of the lifting member. The first drive member 23 is connected to the frame 10 and the movable frame 22. The first drive member 23 is configured to drive the movable frame 22 to switch between the loading position M and the dispensing position N.

[0097] The movable frame 22 is movably mounted on the frame 10 along the first direction Y, meaning the movable frame 22 can move relative to the frame 10 in the first direction Y, so that the movable frame 22 has a loading position M and a picking position N in the first direction Y. When the movable frame 22 is in the loading position M, sheet material 60 can be placed into the hopper 21 mounted on the movable frame 22 to realize the loading of the hopper 21; when the movable frame 22 is in the picking position N, the lifting member 31 can lift the sheet material 60 in the hopper 21 to realize the picking of the sheet material 60 by the feeding mechanism 40.

[0098] For example, in Figure 4 In the middle, the feeding equipment 100 is provided with two feeding mechanisms 20. The two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member. The movable frame 22 of the upper feeding mechanism 20 is located at the material picking position N, and the movable frame 22 of the lower feeding mechanism 20 is located at the material loading position M.

[0099] Optionally, the frame 10 is provided with a slider extending along the first direction Y, and the movable frame 22 is provided with a slide groove extending along the first direction Y. The slide groove and the slider slide together to realize that the movable frame 22 is movably disposed on the frame 10 along the first direction Y. Of course, in some embodiments, the slide groove can also be disposed on the frame 10, and correspondingly, the slider is disposed on the movable frame 22.

[0100] It should be noted that there can be one or more hoppers 21 mounted on the movable frame 22. Figure 4 In this embodiment, the movable frame 22 is provided with multiple hoppers 21. For example, there are six hoppers 21 arranged in a row on the movable frame 22. Of course, in other embodiments, the number of hoppers 21 provided on the movable frame 22 may be two, three, four, or five, etc. In some embodiments, refer to... Figure 6 and Figure 7 , Figure 6 This is a partial structural schematic diagram of the feeding device 100 provided in some embodiments of this application. Figure 7 This is a front view of a partial structure of the feeding device 100 provided in some embodiments of this application. The hopper 21 mounted on the movable frame 22 can also be a single unit.

[0101] The first driving component 23 is configured to drive the movable frame 22 to switch between the loading position M and the unloading position N. That is, the first driving component 23 drives the movable frame 22 to move relative to the frame 10 in the first direction Y, so that the movable frame 22 can move between the loading position M and the unloading position N. For example, the first driving component 23 can be an electric push rod, a cylinder, or a linear motor, etc.

[0102] The feeding mechanism 20 is also equipped with a movable frame 22 and a first driving component 23. The first driving component 23 can drive the movable frame 22 to move relative to the frame 10 in the first direction Y, so as to realize the movement of the movable frame 22 between the loading position M and the picking position N. This can drive the hopper 21 set on the movable frame 22 to switch between the loading position M and the picking position N. On the one hand, it is convenient to load the hopper 21, so that the position for loading the hopper 21 is far away from the position for the feeding mechanism 40 to pick up the sheet material 60. This helps to alleviate the interference phenomenon when loading and picking up the sheet material 60, thereby reducing the safety hazards in the production process. On the other hand, the assembly and subsequent feeding of the sheet material 60 can be realized without manual handling of the sheet material 60 to the picking position N of the movable frame 22, which helps to reduce the intensity of manual labor and save labor costs.

[0103] According to some embodiments of this application, see Figure 4 and Figure 5 As shown, the feeding device 100 includes two feeding mechanisms 20, and the movable frames 22 of the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member.

[0104] In this arrangement, the movable frames 22 of the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member. That is, the hoppers 21 of the movable frames 22 of the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member, so that the movable frames 22 of the two feeding mechanisms 20 do not interfere with each other when they move along the first direction Y. This allows the movable frame 22 of one feeding mechanism 20 to be in the loading position M for loading sheet material 60, while the movable frame 22 of the other feeding mechanism 20 is in the picking position N for the picking unit 41 of the feeding mechanism 40 to pick up the sheet material 60 in the hopper 21.

[0105] It should be noted that the feeding equipment 100 includes two feeding mechanisms 20, but is not limited to two feeding mechanisms 20. For example, in Figure 5In this embodiment, the feeding device 100 is provided with two feeding mechanisms 20 spaced apart along the lifting direction X of the lifting member. In other embodiments, the feeding device 100 may also include three, four, five or six feeding mechanisms 20 spaced apart along the lifting direction X of the lifting member.

[0106] The feeding equipment 100 is equipped with two feeding mechanisms 20 arranged at intervals along the lifting direction X of the lifting component. This allows the movable frame 22 of one feeding mechanism 20 to be in the loading position M for loading, while the movable frame 22 of the other feeding mechanism 20 is in the picking position N for the feeding mechanism 40 to pick up and feed the sheet material 60. This enables the two feeding mechanisms 20 to work together and switch between each other, thereby enabling the feeding equipment 100 to load and feed without stopping, achieving continuous operation of the feeding equipment 100, and thus improving the operating rate of the feeding equipment 100 and increasing the production efficiency of the sheet material 60.

[0107] According to some embodiments of this application, refer to Figure 4 and Figure 5 Please refer to further details. Figure 8 and Figure 9 , Figure 8 This is a schematic diagram of the lifting mechanism 30 of the feeding device 100 provided in some embodiments of this application. Figure 9 This is a front view of the lifting mechanism 30 of the feeding device 100 provided in some embodiments of this application. The lifting mechanism 30 also includes an adjustment assembly 32 connected to the frame 10 and the lifting member 31. The adjustment assembly 32 is configured to adjust the height position of the lifting member 31 in the lifting direction X of the lifting member, so that the lifting member 31 switches between a first lifting position and a second lifting position. The lifting member 31 is configured to: lift the sheet material 60 in the hopper 21 of one feeding mechanism 20 when it is in the first lifting position, and lift the sheet material 60 in the hopper 21 of another feeding mechanism 20 when it is in the second lifting position.

[0108] The adjusting component 32 is mounted on the frame 10 and connected to the lifting member 31. The adjusting component 32 drives the lifting member 31 to move in the lifting direction X, thereby adjusting the position of the lifting member 31 in the height direction and enabling switching between a first lifting position and a second lifting position. The adjusting component 32 can have various structures; for example, it can be a single electric push rod, cylinder, or linear motor. Alternatively, it can be a combination of a motor and a worm gear structure, or a combination of a motor and a rack and pinion structure.

[0109] The lifting member 31 is configured to: lift the sheet material 60 in the hopper 21 of one feeding mechanism 20 when in the first lifting position, and lift the sheet material 60 in the hopper 21 of another feeding mechanism 20 when in the second lifting position. That is, the lifting member 31 can lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20 respectively when in different positions, thereby enabling the lifting member 31 to lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20 that are spaced apart in the lifting direction X of the lifting member while simultaneously allowing the two feeding mechanisms 20 to switch feeding without stopping. For example, in Figure 5 In the middle, two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member. When the lifting member 31 is in the first lifting position, the lifting member 31 can lift the sheet material 60 in the hopper 21 of the upper feeding mechanism 20. When the lifting member 31 is in the second lifting position, the lifting member 31 can lift the sheet material 60 in the hopper 21 of the lower feeding mechanism 20.

[0110] Optionally, the number of lifting members 31 corresponds one-to-one with the number of hoppers 21 in a feeding mechanism 20. When there is one hopper 21 in a feeding mechanism 20, there is also one lifting member 31 connected to the adjusting component 32; when there are multiple hoppers 21 in a feeding mechanism 20, there are also multiple lifting members 31 connected to the adjusting component 32. For example, in Figure 4 and Figure 8 In the middle, there are six material bins 21 set on the movable frame 22, and correspondingly, the lifting mechanism 30 is equipped with six lifting components 31.

[0111] It should be noted that, in this embodiment of the application, the feeding device 100 includes two feeding mechanisms 20 spaced apart along the lifting direction X of the lifting member. The lifting member 31 has a corresponding first lifting position and a second lifting position in the lifting direction X of the lifting member. The adjusting component 32 can drive the lifting member 31 to switch between the first lifting position and the second lifting position. If the feeding device 100 includes three, four, five or six feeding mechanisms 20 spaced apart along the lifting direction X of the lifting member, the lifting member 31 has a corresponding first lifting position, second lifting position, third lifting position, fourth lifting position, fifth lifting position or sixth lifting position in the lifting direction X of the lifting member.

[0112] The lifting mechanism 30 is also provided with an adjustment component 32 for adjusting the height position of the lifting member 31. The adjustment component 32 can drive the lifting member 31 to move in the lifting direction X of the lifting member, so that the lifting member 31 can switch between the first lifting position and the second lifting position. This allows the lifting member 31 to lift the sheet material 60 in the hopper 21 of different feeding mechanisms 20 when it is in different positions. This makes it possible for the lifting member 31 of the lifting mechanism 30 to lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20. This eliminates the need to set the size and lifting stroke of the lifting member 31 in the lifting direction X of the lifting member to meet the needs of the two feeding mechanisms 20, which helps to reduce the assembly difficulty and manufacturing cost of the lifting mechanism 30.

[0113] In some embodiments, see Figure 8 and Figure 9 As shown, the adjustment assembly 32 includes a mounting base 321 and a second drive member 322. The mounting base 321 is movably disposed on the frame 10 along the lifting direction X of the lifting member, and the lifting member 31 is mounted on the mounting base 321. The second drive member 322 is connected to the mounting base 321 and is configured to drive the mounting base 321 to move along the lifting direction X of the lifting member, thereby causing the lifting member 31 to switch between a first lifting position and a second lifting position.

[0114] For example, multiple lifting members 31 are mounted on the mounting base 321, so that when the second driving member 322 drives the mounting base 321 to move along the lifting direction X of the lifting member, it can simultaneously drive the multiple lifting members 31 to switch between the first lifting position and the second lifting position.

[0115] The second driving component 322 drives the mounting base 321 to move in the lifting direction X of the lifting component. The structure of the second driving component 322 can be varied; for example, in... Figure 8 In this embodiment, the second driving component 322 is a cylinder. Of course, in other embodiments, the second driving component 322 can also be an electric push rod or a linear motor, etc.

[0116] The adjustment component 32 is provided with a mounting base 321 and a second drive component 322. The lifting component 31 is disposed on the mounting base 321. The second drive component 322 can drive the mounting base 321 to move in the lifting direction X of the lifting component, so as to drive the lifting component 31 to switch between the first lifting position and the second lifting position. In this way, the lifting component 31 can lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20. This structure is simple, easy to implement, and conducive to improving the automation level of the feeding equipment 100.

[0117] In some embodiments, see Figure 5 , Figure 8 and Figure 9As shown, the adjustment assembly 32 may further include a base 323 and a guide rod 324. The base 323 is connected to the frame 10, and a guide hole 3231 extending along the lifting direction X of the lifting member is provided on the base 323. The second drive member 322 is mounted on the base 323. The guide rod 324 is movably inserted into the guide hole 3231 along the lifting direction X of the lifting member, and the guide rod 324 is connected to the mounting base 321.

[0118] The guide rod 324 is movably inserted into the guide hole 3231 along the lifting direction X of the lifting member. That is, the guide rod 324 extends along the lifting direction X of the lifting member and is movably disposed in the guide hole 3231 of the base 323 along the lifting direction X of the lifting member, so as to guide the mounting seat 321 connected to the guide rod 324, thereby realizing that the mounting seat 321 moves stably relative to the base 323 along the lifting direction X of the lifting member under the drive of the second driving member 322.

[0119] Optionally, the guide rod 324 connected to the mounting base 321 can be one or more. For example, in... Figure 8 and Figure 9 In this configuration, four guide rods 324 are connected to the mounting base 321, and four guide holes 3231 are correspondingly provided on the base 323. The four guide rods 324 are respectively arranged around the mounting base 321 along its circumference, which helps to further improve the stability of the mounting base 321 during the lifting direction X of the lifting member. Of course, the structure of the adjusting component 32 is not limited to this. In other embodiments, the guide rods 324 connected to the mounting base 321 can also be two, three, or five, etc.

[0120] In some embodiments, the adjusting assembly 32 may further include linear bearings 325, which are correspondingly arranged with guide rods 324. The linear bearings 325 are connected to the base 323, and the guide rods 324 are inserted within the linear bearings 325. The linear bearings 325 assist the guide rods 324 in moving relative to the base 323 along the lifting direction X of the lifting member. This structure helps to further improve the stability and smoothness of the movement of the guide rods 324 along the lifting direction X of the lifting member. The specific structure of the linear bearings 325 can be found in related technologies and will not be described in detail here.

[0121] The adjustment assembly 32 is also provided with a base 323 and a guide rod 324. By providing a guide hole 3231 on the base 323 and inserting the guide rod 324 movably into the guide hole 3231 along the lifting direction X of the lifting member, the guide rod 324 can guide the mounting base 321 when the second driving member 322 drives the mounting base 321 to move along the lifting direction X of the lifting member, thereby improving the stability of the mounting base 321 when it moves along the lifting direction X of the lifting member.

[0122] According to some embodiments of this application, see Figure 4 and Figure 8 As shown, the lifting mechanism 30 also includes a first detection element 33, which is mounted on the lifting element 31, and the first detection element 33 and the lifting element 31 are configured in a one-to-one correspondence. The first detection element 33 is configured to detect the sheet material 60 in the hopper 21 and generate a first signal indicating that there is no sheet material 60 in the hopper 21. The lifting element 31 is configured to reset and disengage from the hopper 21 according to the first signal.

[0123] The first detection element 33 serves to detect whether there is still sheet material 60 in the hopper 21, so that the lifting element 31 can respond to the detection result of the first detection element 33. For example, the structure of the first detection element 33 can be various, such as a pressure sensor, a photosensitive sensor, or a contact sensor.

[0124] The first detection element 33 is set in a one-to-one correspondence with the lifting element 31, that is, each lifting element 31 is provided with a corresponding first detection element 33.

[0125] In some embodiments, refer to Figure 10 , Figure 10 This is a schematic diagram of the hopper 21 of the feeding mechanism 20 of the feeding device 100 provided in some embodiments of this application. The hopper 21 includes a base 211 for placing multiple stacked sheets 60. The base 211 is provided with lifting holes 2111 extending through both sides of the base 211 along the lifting direction X of the lifting member. The lifting member 31 can pass through the lifting holes 2111 to lift the sheets 60 disposed on the base 211. When the first detection member 33 detects that there are no sheets 60 on the base 211, the lifting member 31 can retract from the lifting holes 2111 and reset in response to a first signal from the first detection member 33, thereby realizing the lifting member 31 detaching from the hopper 21.

[0126] The lifting mechanism 30 is also equipped with a first detection element 33, which is installed on the lifting element 31. The first detection element 33 can detect whether there are still pieces of material 60 in the hopper 21, so that when there are no pieces of material 60 in the hopper 21, the lifting element 31 can respond to the first detection element 33 and exit and reset from the hopper 21. This facilitates the first driving element 23 to drive the movable part to switch between the loading position M and the unloading position N, thereby reducing the interference of the lifting element 31 on the hopper 21. Moreover, no manual intervention is required, which helps to improve the automation level of the feeding equipment 100 and improve production efficiency.

[0127] In some embodiments, please continue to see Figure 4 , Figure 8 and Figure 10As shown, the lifting mechanism 30 may further include a second detection element 34, which is mounted on the lifting member 31, and the second detection element 34 is configured to correspond one-to-one with the lifting member 31. The second detection element 34 is configured to detect the reset state of the lifting member 31 and generate a second signal characterizing the reset of the lifting member 31. The adjustment component 32 is configured to adjust the height position of the lifting member 31 in the lifting direction X of the lifting member according to the second signal, and the first drive component 23 is configured to drive the movable frame 22 to switch between the loading position M and the unloading position N according to the second signal.

[0128] The second detection element 34 is used to detect whether the lifting element 31 has been reset, that is, to detect whether the lifting element 31 has exited and disengaged from the hopper 21, so that the first drive element 23 and the adjustment component 32 can respond to the detection result of the second detection element 34. In other words, after the second detection element 34 detects that the lifting element 31 has exited and reset from the lifting hole 2111 of the base 211 of the hopper 21, the adjustment component 32 and the first drive element 23 can both respond to the second signal of the second detection element 34, so that the adjustment component 32 can drive the lifting element 31 to move in the lifting direction X of the lifting element, so as to adjust the height position of the lifting element 31 in the lifting direction X of the lifting element, and so that the first drive element 23 can drive the movable frame 22 to move between the loading position M and the unloading position N.

[0129] For example, the structure of the second detection element 34 can be various, such as an ultrasonic ranging sensor, an infrared travel sensor, or a contact sensor.

[0130] The second detection element 34 is set in a one-to-one correspondence with the lifting element 31, that is, each lifting element 31 is provided with a corresponding second detection element 34.

[0131] The lifting mechanism 30 is also equipped with a second detection element 34, which is installed on the lifting element 31. The second detection element 34 can detect the reset state of the lifting element 31, so that the adjustment component 32 of the lifting mechanism 30 responds to the second detection element 34 and drives the lifting element 31 to switch between the first lifting position and the second lifting position. The first drive component 23 responds to the second detection element 34 and drives the movable frame 22 to switch between the loading position M and the unloading position N. This enables the feeding equipment 100 to switch between the two feeding mechanisms 20 without stopping the machine, without manual intervention, which helps to improve the automation level of the feeding equipment 100 and improve production efficiency.

[0132] According to some embodiments of this application, please refer to Figure 4 and Figure 8 As shown, the feeding mechanism 20 includes multiple hoppers 21, all of which are installed on the movable frame 22. Each hopper 21 is corresponding to a lifting component 31.

[0133] In this configuration, each hopper 21 is paired with a lifting component 31, meaning that each hopper 21 of a feeding mechanism 20 is equipped with a corresponding lifting component 31.

[0134] For example, in Figure 4 and Figure 5 In the process, each feeding mechanism 20 has six material bins 21 on its movable frame 22, corresponding to... Figure 8 In the lifting mechanism 30, the mounting base 321 of the adjusting component 32 is provided with six lifting components 31. Of course, in other embodiments, the number of hoppers 21 provided on the movable frame 22 of each feeding mechanism 20 can also be two, three, four or five, etc.

[0135] By setting multiple material bins 21 on the movable frame 22 of the feeding mechanism 20, and setting the lifting component 31 of the lifting mechanism 30 in a one-to-one correspondence with the material bins 21 of each feeding mechanism 20, the feeding mechanism 20 can move the sheet material 60 placed in the multiple material bins 21 to the material picking position N for feeding, which is beneficial to optimizing the production cycle of the feeding equipment 100 and improving the production efficiency of the feeding equipment 100.

[0136] According to some embodiments of this application, see Figure 8 , Figure 9 and Figure 10 As shown, the lifting member 31 includes a self-locking cylinder 311, which is configured to self-lock when the adsorption pressure of the adsorption member 411 reaches a preset value, so as to stop lifting the sheet material 60. The specific structure of the self-locking cylinder 311 can be found in related technologies, and will not be described in detail here.

[0137] The self-locking cylinder 311 is mounted on the mounting base 321 of the adjusting component 32, so that when the second driving member 322 drives the mounting base 321 to move along the lifting direction X of the lifting member, it can drive the self-locking cylinder 311 to switch between the first lifting position and the second lifting position.

[0138] In some embodiments, the lifting member 31 may further include a lifting block 312, which is connected to the output end of the self-locking cylinder 311. The self-locking cylinder 311 is used to drive the lifting block 312 to move along the lifting direction X of the lifting member, so that the lifting block 312 can pass through the lifting hole 2111 on the base 211 of the hopper 21 and lift the sheet material 60 placed on the base 211, thereby realizing the lifting effect of the lifting member 31 on the sheet material 60 in the hopper 21. Of course, the structure of the lifting member 31 is not limited to this. In other embodiments, the lifting member 31 may also be an electric push rod or a linear motor, etc.

[0139] The lifting component 31 is equipped with a self-locking cylinder 311, which can lift the sheet material 60 in the hopper 21. The self-locking cylinder 311 can also self-lock in response to the detection unit 50 when the adsorption pressure of the adsorption component 411 reaches a preset value, so that the lifting component 31 stops lifting the sheet material 60. This type of lifting component 31 has a simple structure, is easy to implement, and has high stability in use. On the other hand, the self-locking of the self-locking cylinder 311 can keep the sheet material 60 in the original position, thereby improving the stability and reliability of the adsorption component 411 of the pickup unit 41 adsorbing and picking up the sheet material 60.

[0140] According to some embodiments of this application, refer to Figure 10 Please refer to further details. Figure 11 , Figure 11 This is a top view of the hopper 21 of the feeding mechanism 20 of the feeding device 100 provided in some embodiments of this application. The hopper 21 includes a base 211 and a plurality of limiting members 212. The base 211 is used to place the sheet material 60, and the base 211 is provided with a lifting hole 2111 through which the lifting member 31 passes along the lifting direction X of the lifting member. The plurality of limiting members 212 are disposed on the base 211 and arranged at intervals around the lifting hole 2111.

[0141] The base 211 is used to place the sheet material 60, that is, multiple sheets of material 60 are stacked on the base 211 along the lifting direction X of the lifting member.

[0142] The base 211 is provided with a lifting hole 2111 through which the lifting member 31 passes along the lifting direction X of the lifting member. That is, the lifting hole 2111 extends along the lifting direction X of the lifting member, and the two ends of the lifting hole 2111 pass through the two sides of the base 211 in the lifting direction X of the lifting member, so that the lifting block 312 of the lifting member 31 can pass through the lifting hole 2111 and lift the sheet material 60 placed on the base 211.

[0143] Multiple limiting members 212 are disposed on the base 211 and arranged at intervals around the lifting hole 2111. That is, multiple limiting members 212 are all installed on one side of the base 211 in the lifting direction X of the lifting member, and multiple limiting members 212 are arranged at intervals along the circumference of the lifting hole 2111.

[0144] For example, in Figure 10 and Figure 11 In this embodiment, six limiting members 212 are provided on the base 211. The six limiting members 212 are arranged circumferentially around the lifting hole 2111 and extend along the lifting direction X of the lifting member. Of course, in other embodiments, the limiting members 212 provided on the base 211 can also be two, three, four, five or seven, etc.

[0145] The hopper 21 is equipped with a base 211 and multiple limiting members 212. A lifting hole 2111 is provided on the base 211 for the lifting member 31 to pass through, allowing the lifting member 31 to enter the hopper 21 and lift the sheet material 60. This structure is simple and easy to implement. Furthermore, by providing multiple limiting members 212 on the base 211, and by arranging these limiting members 212 at intervals around the lifting hole 2111, the limiting members 212 can limit and guide the sheet material 60 placed on the base 211, reducing the possibility of the sheet material 60 falling off or deviating when the lifting member 31 lifts it. This facilitates the normal operation of the feeding equipment 100.

[0146] According to some embodiments of this application, please continue to refer to Figure 10 and Figure 11 As shown, the multiple limiting members 212 include a first limiting member 212a and a second limiting member 212b. Along the first direction Y, the first limiting member 212a is provided on both sides of the lifting hole 2111. Along the second direction Z, the second limiting member 212b is provided on both sides of the lifting hole 2111. The first direction Y, the second direction Z and the lifting direction X of the lifting member are perpendicular to each other.

[0147] In particular, along the first direction Y, the lifting hole 2111 is provided with a first limiting member 212a on both sides, that is, the multiple limiting members 212 include at least two first limiting members 212a, and the lifting hole 2111 is provided with a first limiting member 212a on both sides in the first direction Y.

[0148] Along the second direction Z, the lifting hole 2111 is provided with a second limiting member 212b on both sides, that is, the multiple limiting members 212 include at least two second limiting members 212b, and the lifting hole 2111 is provided with a second limiting member 212b on both sides in the second direction Z.

[0149] For example, in Figure 11 In the design, the plurality of limiting members 212 include four first limiting members 212a, and two first limiting members 212a are respectively provided on both sides of the lifting hole 2111 in the first direction Y. One first limiting member 212a is disposed opposite to the first limiting member 212a located on the other side of the lifting hole 2111 in the first direction Y. Of course, in other embodiments, the first limiting members 212a provided on the base 211 may also be two, six, or eight, etc.

[0150] For example, in Figure 11In the plurality of limiting members 212, there are two second limiting members 212b, which are arranged opposite to each other and are respectively located on both sides of the lifting hole 2111 in the second direction Z. Of course, in other embodiments, there may be four, six or eight second limiting members 212b disposed on the base 211.

[0151] It should be noted that the first direction Y and the second direction Z are the width and length directions of the base 211, respectively, and the corresponding lifting direction X of the lifting component is the thickness direction of the base 211.

[0152] The multiple limiting members 212 include first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y and second limiting members located on both sides of the lifting hole 2111 in the second direction Z, so that the multiple limiting members 212 can limit the sheet material 60 on both sides in the first direction Y and the second direction Z, thereby further improving the limiting and guiding effect of the multiple limiting members 212 on the sheet material 60, so as to further alleviate the phenomenon of the sheet material 60 falling off or running off-center when the lifting member 31 lifts the sheet material 60.

[0153] According to some embodiments of this application, see Figure 10 and Figure 11 As shown, a first limiting member 212a located on at least one side of the lifting hole 2111 is adjustablely disposed on the base 211 along the first direction Y. And / or, a second limiting member 212b located on at least one side of the lifting hole 2111 is adjustablely disposed on the base 211 along the second direction Z.

[0154] In this embodiment, a first limiting member 212a located on at least one side of the lifting hole 2111 is adjustablely disposed on the base 211 along the first direction Y. Specifically, the first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y can be either one side adjustablely disposed on the base 211 along the first direction Y, or both sides adjustablely disposed on the base 211 along the first direction Y. For example, in this embodiment, the first limiting member 212a on one side of the lifting hole 2111 in the first direction Y is fixedly connected to the base 211, while the first limiting member 212a on the other side is adjustablely disposed on the base 211 along the first direction Y. This adjusts the distance between the first limiting members 212a on both sides of the lifting hole 2111 in the first direction Y, thereby meeting the placement requirements of sheet materials 60 of different sizes in the first direction Y.

[0155] A second limiting member 212b located on at least one side of the lifting hole 2111 is adjustablely disposed on the base 211 along the second direction Z. That is, the second limiting members 212b located on both sides of the lifting hole 2111 in the second direction Z can be either a second limiting member 212b on one side adjustablely disposed on the base 211 along the first direction Y, or both second limiting members 212b on both sides adjustablely disposed on the base 211 along the first direction Y. For example, in this embodiment of the application, the second limiting member 212b on one side of the lifting hole 2111 in the second direction Z is fixedly connected to the base 211, and the second limiting member 212b on the other side is adjustablely disposed on the base 211 along the second direction Z, so as to adjust the distance between the second limiting members 212b on both sides of the lifting hole 2111 in the second direction Z, thereby meeting the placement requirements of sheet materials 60 of different sizes in the second direction Z.

[0156] By setting the first limiting member 212a located on at least one side of the lifting hole 2111 in the first direction Y to be adjustablely positioned on the base 211 in the first direction Y, the limiting width of multiple first limiting members 212a on the sheet material 60 in the first direction Y can be adjusted by adjusting the position of the first limiting member 212a in the first direction Y, so as to be suitable for sheet materials 60 of different sizes in the first direction Y, thereby enabling the hopper 21 to store sheet materials 60 of different sizes, which is beneficial to improving the applicability of the hopper 21 and improving the production flexibility of the feeding equipment 100. Similarly, by setting the second limiting member 212b located on at least one side of the lifting hole 2111 in the second direction Z to be adjustablely positioned on the base 211 along the second direction Z, the limiting width of multiple second limiting members 212b on the sheet material 60 in the second direction Z can be adjusted by adjusting the position of the second limiting member 212b in the second direction Z, so as to be suitable for sheet materials 60 of different sizes in the second direction Z, thereby enabling the hopper 21 to store sheet materials 60 of different sizes, which is beneficial to improving the applicability of the hopper 21 and improving the production flexibility of the feeding equipment 100.

[0157] In some embodiments, see Figure 10 and Figure 11 As shown, a first adjustment groove 2112 is provided on the base 211. The first adjustment groove 2112 extends along the first direction Y, and a portion of the first limiting member 212a is movably inserted into the first adjustment groove 2112 along the first direction Y.

[0158] The first limiting member 212a is partially movably inserted into the first adjusting groove 2112 along the first direction Y. That is, the first limiting member 212a has a portion inserted into the first adjusting groove 2112, so that the first limiting member 212a and the first adjusting groove 2112 form a sliding fit relationship, thereby enabling the first limiting member 212a to move along the first direction Y under the limiting and guiding action of the first adjusting groove 2112, so as to adjust the position of the first limiting member 212a relative to the base 211 in the first direction Y.

[0159] Of course, the structure of the hopper 21 is not limited to this. In other embodiments, the structure in which the first limiting member 212a is adjustablely disposed on the base 211 along the first direction Y can also be other structures. For example, the base 211 is provided with a plurality of first adjustment holes, which are arranged at intervals along the first direction Y and extend along the thickness direction of the base 211. The first limiting member 212a has a first insertion part that can be inserted into the first adjustment hole. By inserting the first insertion part of the first limiting member 212a into different first adjustment holes, the position of the first limiting member 212a relative to the base 211 in the first direction Y can be adjusted.

[0160] By providing a first adjustment groove 2112 extending along the first direction Y on the base 211, and partially inserting the first limiting member 212a into the first adjustment groove 2112 along the first direction Y, the position of the first limiting member 212a in the first direction Y can be adjusted. With this structure, the hopper 21 can achieve continuous multi-level adjustment of the position of the first limiting member 212a in the first direction Y to meet the placement requirements of sheet materials 60 of different sizes, thereby further improving the applicability of the hopper 21.

[0161] In some embodiments, see Figure 10 and Figure 11 As shown, a second adjustment groove 2113 is provided on the base 211. The second adjustment groove 2113 extends along the second direction Z, and a portion of the second limiting member 212b is movably inserted into the second adjustment groove 2113 along the second direction Z.

[0162] The second limiting member 212b is partially movably inserted into the second adjusting groove 2113 along the second direction Z. That is, the second limiting member 212b has a portion inserted into the second adjusting groove 2113, so that the second limiting member 212b and the second adjusting groove 2113 form a sliding fit relationship. This enables the second limiting member 212b to move along the second direction Z under the limiting and guiding action of the second adjusting groove 2113, so as to adjust the position of the second limiting member 212b relative to the base 211 in the second direction Z.

[0163] Of course, the structure of the hopper 21 is not limited to this. In other embodiments, the structure in which the second limiting member 212b is adjustablely disposed on the base 211 along the second direction Z can also be other structures. For example, the base 211 is provided with a plurality of second adjustment holes, which are arranged at intervals along the second direction Z and extend along the thickness direction of the base 211. The second limiting member 212b has a second insertion part that can be inserted into the second adjustment hole. By inserting the second insertion part of the second limiting member 212b into different second adjustment holes, the position of the second limiting member 212b relative to the base 211 in the second direction Z can be adjusted.

[0164] By providing a second adjustment groove 2113 extending along the second direction Z on the base 211, and partially inserting the second limiting member 212b into the second adjustment groove 2113 along the second direction Z, the position of the second limiting member 212b in the second direction Z can be adjusted. With this structure, the hopper 21 can achieve continuous multi-level adjustment of the position of the second limiting member 212b in the second direction Z to meet the placement requirements of sheet materials 60 of different sizes, thereby further improving the applicability of the hopper 21.

[0165] According to some embodiments of this application, refer to Figure 10 and Figure 11 Please refer to further details. Figure 12 and Figure 13 , Figure 12 This is a front view of the hopper 21 of the feeding mechanism 20 of the feeding equipment 100 provided in some embodiments of this application. Figure 13 for Figure 12 The diagram shows a partial enlarged view of point A in the hopper 21. The hopper 21 also includes a first separating component 213 and a second separating component 214. At least one first limiting component 212a is provided with the first separating component 213, and at least one first limiting component 212a is provided with the second separating component 214. Along the lifting direction X of the lifting component, the first separating component 213 is located above the second separating component 214. Both the first separating component 213 and the second separating component 214 are configured to separate two stacked pieces 60 during the process of the feeding mechanism 40 picking up the pieces 60 in the hopper 21.

[0166] In this embodiment, at least one first limiting member 212a is provided with a first distributing member 213, that is, one first limiting member 212a may be provided with a first distributing member 213, or multiple first limiting members 212a may all be provided with a first distributing member 213; the first limiting member 212a located on one side of the lifting hole 2111 in the first direction Y may be provided with a first distributing member 213, or the first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y may all be provided with a first distributing member 213.

[0167] For example, in Figure 10 and Figure 11 In the first direction Y, a set of first limiting members 212a located on both sides of the lifting hole 2111 and arranged opposite to each other are provided with first material separating members 213.

[0168] At least one first limiting member 212a is provided with a second distributing member 214. That is, there may be one first limiting member 212a with a second distributing member 214, or there may be multiple first limiting members 212a with a second distributing member 214. The second distributing member 214 may be provided on one side of the lifting hole 2111 in the first direction Y, or the second distributing member 214 may be provided on both sides of the lifting hole 2111 in the first direction Y.

[0169] For example, in Figure 10 and Figure 11 In the first direction Y, a set of first limiting members 212a located on both sides of the lifting hole 2111 and arranged opposite to each other are provided with second material distribution members 214.

[0170] It should be noted that the first separating component 213 and the second separating component 214 can be disposed on the same first limiting component 212a, or they can be disposed on two different first limiting components 212a. For example, in... Figure 10 In the middle, the first material distribution component 213 and the second material distribution component 214 are respectively disposed on the two first limiting components 212a.

[0171] The first separating component 213 and the second separating component 214 are both configured to separate two stacked sheets 60 during the process of the feeding mechanism 40 picking up the sheet 60 in the hopper 21. That is, during the process of the feeding mechanism 40 picking up the sheet 60 in the hopper 21, the first separating component 213 and the second separating component 214 contact the sheet 60 in the first direction Y to play a dispensing role on the sheet 60, thereby realizing the separation of two stacked sheets 60.

[0172] Optionally, the structures of the first separating component 213 and the second separating component 214 can be various, such as brushes, springs, etc. For example, in... Figure 13 In the middle, both the first sub-component 213 and the second sub-component 214 are brushes.

[0173] The hopper 21 is also provided with a first separating component 213 and a second separating component 214. The first separating component 213 is positioned above the second separating component 214 in the lifting direction X of the lifting component. Thus, when the feeding mechanism 40 picks up the sheet material 60 in the hopper 21, the first separating component 213 and the second separating component 214 can separate the sheet material 60 twice, thereby improving the separation effect of the sheet material 60 stacked on top of each other. This can effectively alleviate the phenomenon of the feeding mechanism 40 carrying material when picking up the sheet material 60, so as to realize the single picking of the sheet material 60.

[0174] According to some embodiments of this application, see Figure 10 and Figure 11 As shown, the first dividing component 213 and the second dividing component 214 are respectively disposed on two first limiting components 212a. That is, the first dividing component 213 and the second dividing component 214 are respectively located on two different first limiting components 212a.

[0175] In one embodiment where a set of first limiting members 212a located on both sides of the lifting hole 2111 along the first direction Y and arranged opposite to each other are provided with first separating members 213 and second separating members 214, the first separating members 213 and second separating members 214 are respectively provided on two first limiting members 212a, that is, the two first separating members 213 are provided on a set of first limiting members 212a located on both sides of the lifting hole 2111 along the first direction Y, and the two second separating members 214 are provided on another set of first limiting members 212a located on both sides of the lifting hole 2111 along the first direction Y.

[0176] By setting the first sub-component 213 and the second sub-component 214 on different first limiting members 212a, it is easier to assemble the first sub-component 213 and the second sub-component 214, which helps to reduce the assembly difficulty and effectively alleviates the interference between the first sub-component 213 and the second sub-component 214.

[0177] According to some embodiments of this application, see Figure 10 , Figure 11 and Figure 12 As shown, along the first direction Y, at least one set of two oppositely arranged first limiting members 212a are each provided with a first dividing member 213, and the two first dividing members 213 are arranged opposite to each other. At least one set of two oppositely arranged first limiting members 212a are each provided with a second dividing member 214, and the two second dividing members 214 are arranged opposite to each other.

[0178] In this configuration, at least one set of two opposing first limiting members 212a are each provided with a first distributing member 213. The two first distributing members 213 are arranged opposite to each other. This means that either one set of first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y is provided with a first distributing member 213, or multiple sets of first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y are provided with a first distributing member 213.

[0179] For example, in Figure 10 and Figure 11 In this case, only one set of two first limiting members 212a that are arranged opposite each other are provided with a first material distribution member 213. That is to say, the two first limiting members 212a that are located on both sides of the lifting hole 2111 and are arranged opposite each other in the first direction Y are provided with a first material distribution member 213, and the two first material distribution members 213 are arranged opposite each other along the first direction Y.

[0180] At least one set of two opposing first limiting members 212a are each provided with a second distributing member 214. The two second distributing members 214 are arranged opposite to each other. That is, a set of first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y are each provided with a second distributing member 214, or multiple sets of first limiting members 212a located on both sides of the lifting hole 2111 in the first direction Y are each provided with a second distributing member 214.

[0181] For example, in Figure 10 and Figure 11 In this case, each of the two first limiting members 212a that are arranged opposite to each other is provided with a second dividing member 214. That is, each of the two first limiting members 212a that are located on both sides of the lifting hole 2111 and are arranged opposite to each other in the first direction Y is provided with a second dividing member 214, and the two second dividing members 214 are arranged opposite to each other in the first direction Y.

[0182] It should be noted that the two first dividing components 213 and the two second dividing components 214 can be disposed on the same set of two first limiting components 212a disposed opposite to each other in the first direction Y, or they can be disposed on two separate sets of first limiting components 212a. That is, the two first dividing components 213 are disposed on one set of two first limiting components 212a disposed opposite to each other in the first direction Y, and the two second dividing components 214 are disposed on another set of two first limiting components 212a disposed opposite to each other in the first direction Y. For example, in Figure 10 and Figure 11 In the middle, two first material distribution components 213 and two second material distribution components 214 are respectively disposed on two sets of first limiting components 212a.

[0183] By providing a first material separating component 213 to each of the first limiting components 212a arranged opposite to each other in the first direction Y, and the two first material separating components 213 being arranged opposite to each other, and correspondingly, providing a second material separating component 214 to each of the first limiting components 212a arranged opposite to each other in the first direction Y, and the two second material separating components 214 being arranged opposite to each other, the material separating effect of the sheet 60 can be improved by the two first material separating components 213 and the two second material separating components 214 being arranged opposite to each other, so as to further alleviate the phenomenon of material carrying when the feeding mechanism 40 picks up the sheet 60, so as to realize the single picking of the sheet 60.

[0184] According to some embodiments of this application, see Figure 12 and Figure 13 As shown, along the first direction Y, the distance between two oppositely arranged first sub-components 213 is less than the distance between two oppositely arranged second sub-components 214.

[0185] Specifically, the distance between two oppositely arranged first material distribution components 213 is less than the distance between two oppositely arranged second material distribution components 214. That is, the distance between the two first material distribution components 213 located above the second material distribution component 214 in the lifting direction X of the lifting component in the first direction Y is less than the distance between the two second material distribution components 214 located below the first material distribution component 213 in the lifting direction X of the lifting component in the first direction Y. In other words, the space between the two first material distribution components 213 for the sheet material 60 to pass through is less than the space between the two second material distribution components for the sheet material 60 to pass through.

[0186] By setting the spacing between the two first separating components 213 in the first direction Y to be smaller than the spacing between the second separating components 214 in the first direction Y, the first separating components 213 and the second separating components 214 exert different feeding forces on the sheet material 60. This allows the two second separating components 214 located below the first separating component 213 to perform preliminary separation of the sheet material 60, and then the two first separating components 213 located above the second separating component 214 to further separate the sheet material 60. This helps to improve the separation effect of the two stacked sheet materials 60, so as to achieve single picking of the sheet material 60.

[0187] In some embodiments, see Figure 13 As shown, both the first dividing component 213 and the second dividing component 214 are brushes, and the hardness of the bristles of the first dividing component 213 is less than that of the bristles of the second dividing component 214.

[0188] The hardness of the bristles of the first dividing component 213 is less than that of the bristles of the second dividing component 214, meaning that the diameter of the bristles of the first dividing component 213 is smaller than that of the bristles of the second dividing component 214.

[0189] Both the first separating component 213 and the second separating component 214 are brushes, which have a simple structure and facilitate the separation of sheet material 60. In addition, by setting the hardness of the bristles of the first separating component 213 to be less than that of the bristles of the second separating component 214, damage to the sheet material 60 caused by the two first separating components 213 located above the second separating component 214 and with a small distance between them is reduced, and the separating effect of the two first separating components 213 on the sheet material 60 is improved.

[0190] According to some embodiments of this application, refer to Figure 2 and Figure 3 Please refer to further details. Figure 14 , Figure 15 and Figure 16 , Figure 14 This is a schematic diagram of the structure of the picking unit 41 of the feeding mechanism 40 of the feeding device 100 provided in some embodiments of this application. Figure 15 This is a bottom view of the picking unit 41 of the feeding mechanism 40 of the feeding device 100 provided in some embodiments of this application. Figure 16 This is an axial view of the picking unit 41 of the feeding mechanism 40 of the feeding device 100 provided in some embodiments of this application. The picking unit 41 may also include a connecting seat 412, which is connected to the actuator 42. At least one set of adsorption elements 411 is provided on the connecting seat 412. Each set of adsorption elements 411 includes multiple adsorption elements 411, and each set of adsorption elements 411 corresponds to adsorbing a piece of sheet 60 in a hopper 21.

[0191] The connecting seat 412 has a connecting part 4121, which is used to connect to the output end of the actuator 42 so that the actuator 42 can drive the connecting seat 412 to move.

[0192] The connector 412 is provided with at least one set of adsorption elements 411, meaning the pickup unit 41 can have only one set of adsorption elements 411 on the connector 412, or it can have multiple sets of adsorption elements 411 on the connector 412. For example, in... Figure 4 and Figure 5 In the process, each feeding mechanism 20 has six material bins 21 on its movable frame 22, corresponding to... Figure 16 In this embodiment, the pickup unit 41 includes six sets of adsorption elements 411, all of which are disposed on the connecting seat 412. Each set of adsorption elements 411 is used to adsorb the sheet material 60 in one hopper 21. Of course, in other embodiments, the pickup unit 41 may also be provided with two, three, four, five or seven sets of adsorption elements 411.

[0193] Each set of adsorption elements 411 includes multiple adsorption elements 411, and each set of adsorption elements 411 corresponds to adsorbing one piece of sheet 60 in the hopper 21. That is, each set of adsorption elements 411 is composed of multiple adsorption elements 411, so that the multiple adsorption elements 411 in each set of adsorption elements 411 cooperate to adsorb one piece of sheet 60. For example, in Figure 15 and Figure 16 In this embodiment, each group of adsorbents 411 includes three adsorbents 411, which work together to adsorb a sheet 60. Of course, in other embodiments, the number of adsorbents 411 in each group of adsorbents 411 may also be two, four, or five, etc.

[0194] For example, the adsorption element 411 is a suction cup. It should be noted that each adsorption element 411 may have one or more suction cups. For example, in this embodiment of the application, each adsorption element 411 is provided with two suction cups.

[0195] The pickup unit 41 is provided with a connecting seat 412 connected to the actuator 42, and the adsorption element 411 is provided on the connecting seat 412, so that the actuator 42 can drive the adsorption element 411 to move and adsorb and pick up the sheet material 60 in the hopper 21. In addition, the connecting seat 412 is provided with at least one set of adsorption elements 411, and each set of adsorption elements 411 includes multiple adsorption elements 411, so that multiple adsorption elements 411 can cooperate to adsorb the sheet material 60 in a hopper 21, which helps to improve the picking stability of the pickup unit 41 in picking up the sheet material 60, thereby reducing the risk of the sheet material 60 falling off during the transfer and loading process.

[0196] According to some embodiments of this application, please refer to Figure 14 , Figure 15 and Figure 16 As shown, each set of adsorption elements 411 includes three non-collinear adsorption elements 411, and at least one of the three adsorption elements 411 is adjustablely positioned on the connecting seat 412 along the lifting direction X perpendicular to the lifting element.

[0197] Each group of adsorption elements 411 includes three non-collinear adsorption elements 411. That is, each group of adsorption elements 411 is provided with three adsorption elements 411, and the three adsorption elements 411 are not collinear, that is, the three adsorption elements 411 together define a plane.

[0198] At least one of the three adsorption elements 411 is adjustablely positioned on the connecting seat 412 in a direction perpendicular to the lifting direction X of the lifting element. That is, in a direction perpendicular to the lifting direction X of the lifting element, one of the three adsorption elements 411 may be adjustablely positioned on the connecting seat 412, two adsorption elements 411 may be adjustablely positioned on the connecting seat 412, or all three adsorption elements 411 may be adjustablely positioned on the connecting seat 412.

[0199] Each set of adsorption elements 411 on the connecting seat 412 of the pickup unit 41 includes three non-collinear adsorption elements 411, which helps to further improve the adsorption stability and reliability of each set of adsorption elements 411 on the sheet material 60. In addition, by setting at least one of the three adsorption elements 411 to be positionably disposed on the connecting seat 412, the distance between the three adsorption elements 411 can be adjusted to meet the pickup requirements of sheet materials 60 of different sizes, which helps to improve the applicability of the pickup unit 41 and thus effectively improves the production flexibility of the feeding equipment 100.

[0200] In some embodiments, see Figure 15 and Figure 16 As shown, the three adsorption components 411 include a first adsorption component 411a, a second adsorption component 411b, and a third adsorption component 411c. The first adsorption component 411a is fixedly connected to the connecting seat 412. The second adsorption component 411b is spaced apart from the first adsorption component 411a along the first direction Y, and its position is adjustable along the first direction Y in the connecting seat 412. The third adsorption component 411c is spaced apart from both the first adsorption component 411a and the second adsorption component 411b along the second direction Z, and its position is adjustable along the second direction Z in the connecting seat 412. The first direction Y, the second direction Z, and the lifting direction X of the lifting component are all perpendicular to each other.

[0201] The second adsorbent 411b is spaced apart from the first adsorbent 411a along the first direction Y. The second adsorbent 411b is adjustablely positioned on the connecting seat 412 along the first direction Y. That is, the second adsorbent 411b is spaced apart from the first adsorbent 411a in the first direction Y, and its position relative to the first adsorbent 411a in the first direction Y is adjustable. This allows the spacing between the second adsorbent 411b and the first adsorbent 411a in the first direction Y to accommodate sheet materials 60 of different sizes in the first direction Y.

[0202] For example, the connecting seat 412 is provided with a first moving groove 4122 extending along the first direction Y. The first moving groove 4122 is provided in correspondence with the second adsorption member 411b. A portion of the second adsorption member 411b is movably inserted into the first moving groove 4122 along the first direction Y, so that the second adsorption member 411b is adjustablely positioned on the connecting seat 412 along the first direction Y. Of course, the structure of the pickup unit 41 is not limited to this. In other embodiments, the structure in which the second adsorption member 411b is adjustablely disposed on the connecting seat 412 along the first direction Y can also be other structures. For example, the connecting seat 412 is provided with a plurality of third adjustment holes, which are arranged at intervals along the first direction Y and extend along the lifting direction X of the lifting member. The second adsorption member 411b has a third insertion part that can be inserted into the third adjustment hole. By inserting the third insertion part of the second adsorption member 411b into different third adjustment holes, the position of the second adsorption member 411b relative to the connecting seat 412 in the first direction Y can be adjusted.

[0203] The third adsorbent 411c is spaced apart from the first adsorbent 411a and the second adsorbent 411b along the second direction Z. The third adsorbent 411c is adjustablely positioned on the connecting seat 412 along the second direction Z. That is, the third adsorbent 411c is spaced apart from the first adsorbent 411a and the second adsorbent 411b along the second direction Z so that the first adsorbent 411a, the second adsorbent 411b and the third adsorbent 411c are not collinear. The third adsorbent 411c can be adjusted relative to the first adsorbent 411a in the second direction Z, so that the distance between the third adsorbent 411c and the first adsorbent 411a in the second direction Z can be adjusted to accommodate sheet materials 60 of different sizes in the second direction Z.

[0204] For example, the connecting seat 412 is provided with a second moving groove 4123 extending along the second direction Z. The second moving groove 4123 is provided in a one-to-one correspondence with the third adsorption member 411c. A portion of the third adsorption member 411c is movably inserted into the second moving groove 4123 along the second direction Z, so that the third adsorption member 411c is adjustablely positioned on the connecting seat 412 along the second direction Z. Of course, the structure of the pickup unit 41 is not limited to this. In other embodiments, the structure in which the third adsorption member 411c is adjustablely disposed on the connecting seat 412 along the second direction Z can also be other structures. For example, the connecting seat 412 is provided with a plurality of fourth adjustment holes, which are arranged at intervals along the second direction Z and extend along the lifting direction X of the lifting member. The third adsorption member 411c has a fourth insertion part that can be inserted into the fourth adjustment hole. By inserting the fourth insertion part of the third adsorption member 411c into different fourth adjustment holes, the position of the third adsorption member 411c relative to the connecting seat 412 in the second direction Z can be adjusted.

[0205] Each set of adsorption elements 411 includes three adsorption elements 411, including a first adsorption element 411a fixedly connected to the connecting seat 412, a second adsorption element 411b whose position is adjustable along the first direction Y, and a third adsorption element 411c whose position is adjustable along the second direction Z. By adjusting the position of the second adsorption element 411b in the first direction Y and adjusting the position of the third adsorption element 411c in the second direction Z, the spacing of the three adsorption elements 411 in each set of adsorption elements 411 in the first direction Y and the second direction Z can be adjusted to accommodate sheet materials 60 of different sizes in the first direction Y and the second direction Z, thereby further improving the applicability of the pickup unit 41.

[0206] According to some embodiments of this application, see Figure 15 and Figure 16 As shown, the connector 412 is provided with multiple sets of adsorption elements 411.

[0207] For example, in the embodiments of this application, see Figure 4 and Figure 5 As shown, each feeding mechanism 20 has six material bins 21 on its movable frame 22. Figure 15 and Figure 16 In the process, the pickup unit 41 includes six sets of adsorption elements 411, all of which are disposed on the connecting seat 412. Each set of adsorption elements 411 is used to adsorb the sheet material 60 in one hopper 21. Of course, in other embodiments, two, three, four, five or seven sets of adsorption elements 411 may also be disposed on the connecting seat 412.

[0208] By setting multiple sets of adsorption elements 411 on the connecting seat 412, the picking unit 41 can simultaneously pick up the sheet material 60 in multiple hoppers 21, so as to feed multiple sheet materials 60 at the same time, which helps to optimize the production cycle of the feeding equipment 100 and improve the production efficiency of the feeding equipment 100.

[0209] According to some embodiments of this application, this application provides a feeding device 100 for feeding and assembling sheet materials 60. See also... Figures 1 to 16As shown, the feeding device 100 includes a frame 10, two feeding mechanisms 20, a lifting mechanism 30, a feeding mechanism 40, and a detection unit 50. Both feeding mechanisms 20 are mounted on the frame 10 and are arranged at intervals along the lifting direction X of the lifting member. Each feeding mechanism 20 includes a hopper 21, a movable frame 22, and a first driving member 23. The hopper 21 is mounted on the movable frame 22 and is used to hold multiple stacked sheets 60. The movable frame 22 is movably disposed on the frame 10 along a first direction Y. The movable frame 22 has a loading position M for placing sheets 60 into the hopper 21 and a dispensing position N for the lifting member 31 to lift the sheets 60 from the hopper 21. The first direction Y is perpendicular to the lifting direction X of the lifting member. The first driving member 23 is connected to the frame 10 and the movable frame 22, and is configured to drive the movable frame 22 to switch between the loading position M and the dispensing position N. The lifting mechanism 30 includes a lifting member 31 and an adjusting assembly 32. The lifting member 31 includes a self-locking cylinder 311 and a lifting block 312. The self-locking cylinder 311 is connected to the frame 10 via the adjusting assembly 32. The lifting block 312 is connected to the output end of the self-locking cylinder 311. The self-locking cylinder 311 drives the lifting block 312 to move along the lifting direction X of the lifting member to lift the sheet material 60 in the hopper 21. The adjusting assembly 32 is configured to adjust the height position of the lifting member 31 in the lifting direction X of the lifting member, so that the lifting member 31 switches between a first lifting position and a second lifting position. The lifting member 31 is configured to lift the sheet material 60 in the hopper 21 of one feeding mechanism 20 when it is in the first lifting position, and lift the sheet material 60 in the hopper 21 of another feeding mechanism 20 when it is in the second lifting position. The adjustment assembly 32 includes a mounting base 321, a second drive member 322, a base 323, and a guide rod 324. The base 323 is connected to the frame 10 and has a guide hole 3231 extending along the lifting direction X of the lifting member. The second drive member 322 is mounted on the base 323. The guide rod 324 is movably inserted into the guide hole 3231 along the lifting direction X of the lifting member and is connected to the mounting base 321. The self-locking cylinder 311 of the lifting member 31 is mounted on the mounting base 321. The second drive member 322 is connected to the mounting base 321 and is configured to drive the mounting base 321 to move along the lifting direction X of the lifting member, thereby switching the lifting member 31 between a first lifting position and a second lifting position. The feeding mechanism 40 includes a pickup unit 41 and an actuator 42. The pickup unit 41 includes an adsorption element 411, which is connected to the actuator 42. The actuator 42 is configured to drive the pickup unit 41 to move so that the adsorption element 411 picks up the sheet material 60. A detection unit 50 is disposed on the pickup unit 41 and is used to detect the adsorption pressure of the adsorption element 411 on the sheet material 60. The lifting element 31 is configured to stop lifting the sheet material 60 when the adsorption pressure reaches a preset value.

[0210] According to some embodiments of this application, this application also provides a method for feeding sheet 60, applicable to the feeding equipment 100 of any of the above schemes, see reference. Figure 1 , Figure 2 and Figure 3 Please refer to further details. Figure 17 , Figure 17 This is a flowchart illustrating a method for feeding sheet 60 according to some embodiments of this application. The method for feeding sheet 60 includes:

[0211] S100: The actuator 42 drives the pickup unit 41 to move above the sheet material 60;

[0212] S200: The lifting member 31 lifts the sheet material 60 in the hopper 21 so that the sheet material 60 abuts against the adsorption member 411. When the adsorption pressure of the adsorption member 411 adsorbing the sheet material 60 reaches the preset value, the lifting member 31 stops lifting the sheet material 60.

[0213] S300: The actuator 42 transfers the sheet material 60 adsorbed by the adsorption member 411 to the feeding position to feed the sheet material 60.

[0214] In the above-described feeding method, the feeding method for sheet material 60 is as follows: first, the actuator 42 drives the pickup unit 41 to move above the sheet material 60 in the hopper 21; then, the lifting member 31 lifts the sheet material 60 so that the uppermost sheet material 60 can abut against the adsorption member 411, allowing the adsorption member 411 to adsorb the sheet material 60. When the adsorption pressure of the adsorption member 411 reaches a preset value, the lifting member 31 stops lifting the sheet material 60. After the adsorption member 411 has adsorbed the sheet material 60, the actuator 42 drives the pickup unit 41 to move and feed the sheet material 60. This feeding method eliminates the need for complex lifting positions for the lifting member 31 of the lifting mechanism 30. The high precision and programming requirements mean that the lifting position control of the lifting component 31 can be achieved simply by judging whether to stop based on the adsorption pressure of the adsorption component 411. This improves the accuracy of the adsorption component 411 in picking up the sheet material 60, reducing the phenomenon of the sheet material 60 not being picked up due to positional differences between the adsorption component 411 and the sheet material 60. It can also effectively reduce the manufacturing cost and programming cost of the lifting mechanism 30. On the other hand, when lifting and feeding sheet materials 60 of different thicknesses, there is no need to replace the lifting component 31 or reprogram the lifting position of the lifting component 31. This helps to improve the applicability and production flexibility of the feeding equipment 100, making the feeding equipment 100 highly compatible.

[0215] According to some embodiments of this application, refer to Figure 18 , Figure 18This is a flowchart illustrating a method for feeding sheet material 60 according to some embodiments of this application. In step S200: before the sheet material 60 in the hopper 21 is lifted by the lifting member 31 to abut against the adsorption member 411, the method for feeding sheet material 60 may further include:

[0216] S400: Open the adsorption element 411 to allow the adsorption element 411 to draw in air.

[0217] Before step S200, step S400 is performed first: the adsorption member 411 is opened to allow the adsorption member 411 to draw in air. That is, before the lifting member 31 lifts the sheet material 60 in the hopper 21, the adsorption member 411 is opened first to allow the adsorption member 411 to start operating. Thus, when the lifting member 31 lifts the sheet material 60 to abut against the adsorption member 411, the adsorption member 411 can adsorb the sheet material 60.

[0218] In the above-mentioned feeding method, before the lifting member 31 lifts the sheet material 60, the adsorption member 411 is opened to allow the adsorption member 411 to draw in air. This allows the adsorption member 411 to adsorb the sheet material 60 when the lifting member 31 lifts it to abut against the adsorption member 411. This allows the adsorption member 411 to adsorb the sheet material 60 at the same time as the lifting member 31 lifts it, thereby reducing the lifting stroke of the lifting member 31 on the sheet material 60 and reducing the difficulty of program control of the feeding equipment 100.

[0219] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0220] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
