Description

Feeding equipment and sheet material feeding method Technical Field

[0001] The present application relates to the field of production and manufacturing technology, and in particular to a feeding device and a sheet material feeding method. Background Art

[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 them, sheet materials are generally lightweight and thin. For example, components such as thermal insulation pads, insulating pads, pole pieces, or current collectors in batteries are difficult to load and assembly automatically. Due to the low compatibility of sheet materials, manual loading is currently the common method. This results in high labor intensity and low work efficiency during the sheet assembly process, which is not conducive to improving sheet material loading efficiency and assembly costs.

[0003] Summary of the Invention

[0004] The embodiments of the present application provide a loading device and a sheet material loading method, which can effectively reduce the automated assembly cost of the sheet material and improve the compatibility of the sheet material for automated loading.

[0005] In the first aspect, an embodiment of the present application provides a loading device, comprising a frame, a feeding mechanism, a lifting mechanism, a loading mechanism and a detection unit; the feeding mechanism is arranged on the frame, the feeding mechanism includes a hopper, and the hopper is used to place a plurality of stacked sheets; the lifting mechanism is arranged on the frame, the lifting mechanism includes a lifting member, and the lifting member is configured to lift the sheet in the hopper; the loading mechanism includes a picking unit and an actuator, the picking unit includes an adsorption member, the picking unit is connected to the actuator, and the actuator is configured to drive the picking unit to move so that the adsorption member picks up the sheet; the detection unit is used to detect the adsorption pressure of the adsorption member on the sheet, and the lifting member is configured to stop lifting the sheet when the adsorption pressure reaches a preset value.

[0006] In the above technical solution, the lifting parts of the lifting mechanism can lift multiple sheets in the hopper, so that the sheet located on the uppermost side of the multiple sheets can be against the adsorption part of the picking unit, so that the adsorption part can adsorb and pick up the sheet, and the adsorption pressure of the adsorption part on the sheet is detected by the detection unit, so that when the adsorption pressure of the adsorption part reaches a preset value, the lifting parts of the lifting mechanism can respond to the detection unit and stop lifting the sheet to keep the sheet still, so as to facilitate the transfer and loading of the sheet after the adsorption part picks up the sheet, so as to improve the loading efficiency of the sheet. The loading equipment adopting this structure does not need to set complex lifting position programming and high precision for the lifting parts of the lifting mechanism. The requirement is that the lifting position of the lifting part can be controlled by judging whether the lifting part stops lifting through the adsorption pressure of the adsorption part, so as to realize the automatic loading of the sheet material, thereby improving the accuracy of the adsorption part in picking up the sheet material, so as to reduce the phenomenon that the sheet material cannot be picked up due to the position difference between the adsorption part and the sheet material, and can effectively reduce the manufacturing cost and program programming cost of the lifting mechanism, so as to reduce the automatic assembly cost of the sheet material. On the other hand, when lifting and loading sheets of different thicknesses, there is no need to replace the lifting part, nor to reprogram the lifting position of the lifting part, which is beneficial to improving the application range and production flexibility of the feeding equipment, so that the feeding equipment has higher compatibility.

[0008] In the above technical solution, the feeding mechanism is also provided with a movable frame and a first driving member, which can drive the movable frame to move in the first direction relative to the frame through the first driving member to realize the movement of the movable frame between the loading position and the picking position, thereby driving the hopper provided 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, which is conducive to alleviating the interference phenomenon when loading and picking up the sheet material, so as to reduce the safety hazards in the production process. On the other hand, there is no need to manually transport the sheet material to the picking position of the movable frame to realize the assembly and subsequent loading of the sheet material, which is conducive to reducing labor intensity and saving labor costs.

[0013] In some embodiments, the adjustment assembly includes a mounting seat and a second driving member; the mounting seat is movably arranged on the frame along the lifting direction of the lifting member, and the lifting member is installed on the mounting seat; the second driving member is connected to the mounting seat, and the second driving member is configured to drive the mounting seat to move along the lifting direction of the lifting member to drive the lifting member to switch between the first lifting position and the second lifting position.

[0014] In the above technical solution, the adjustment component is provided with a mounting seat and a second driving member, and the lifting member is provided on the mounting seat, so that the second driving member can drive the mounting seat to move in the lifting direction of the lifting member, so as to drive the lifting member to switch between the first lifting position and the second lifting position, thereby enabling the lifting member to lift the sheet materials in the hoppers of the two feeding mechanisms. This structure is simple, easy to implement, and conducive to improving the degree of automation of the feeding equipment.

[0017] In some embodiments, the lifting mechanism also includes a first detection member, which is installed on the lifting member, and the first detection member is arranged in a one-to-one correspondence with the lifting member; the first detection member is configured to detect the sheet material in the silo and generate a first signal indicating that there is no sheet material in the silo, and the lifting member is configured to reset and detach from the silo according to the first signal.

[0018] In the above technical solution, the jacking mechanism is also provided with a first detection member, which is installed on the jacking member. The first detection member can detect whether there is any sheet material in the hopper through the first detection member, so that the jacking member can respond to the first detection member and exit and reset from the hopper when there is no sheet material in the hopper, thereby facilitating the first driving member to drive the movable member to switch between the loading position and the material taking position, so as to reduce the interference effect of the jacking member on the hopper, and no manual participation is required, which is conducive to improving the degree of automation of the feeding equipment and thus improving production efficiency.

[0019] In some embodiments, the lifting mechanism further includes a second detection member, which is mounted on the lifting member, and the second detection member is arranged in a one-to-one correspondence with the lifting member; the second detection member is configured to detect the reset state of the lifting member and generate a second signal representing 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 driving member is configured to drive the movable frame to switch between the loading position and the picking position according to the second signal.

[0020] In the above technical solution, the jacking mechanism is also provided with a second detection member, and the second detection member is installed on the jacking member.

[0021] In some embodiments, the feeding mechanism includes a plurality of the silos, and the plurality of the silos are all installed on the movable frame, and the silos are arranged in a one-to-one correspondence with the lifting members.

[0022] In the above technical solution, multiple silos are arranged on the movable frame of the feeding mechanism, and the lifting parts of the lifting mechanism are arranged one-to-one corresponding to the silos of each feeding mechanism, so that the feeding mechanism can move the sheets placed in multiple silos to the material taking position for loading, which is conducive to optimizing the production rhythm of the loading equipment and improving the production efficiency of the loading equipment.

[0023] In some embodiments, the lifting member includes a self-locking cylinder, which is configured to self-lock when the adsorption pressure of the adsorption member reaches a preset value to stop lifting the sheet.

[0024] In the above technical solution, the lifting part is provided with a self-locking cylinder, so that the sheet material in the hopper can be lifted by the self-locking cylinder, and the self-locking cylinder can self-lock in response to the detection unit when the adsorption pressure of the adsorption part reaches a preset value, so that the lifting part stops lifting the sheet material. On the one hand, the lifting part of this structure is simple in structure, 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 place, so as to improve the stability and reliability of the adsorption and picking up of the sheet material by the adsorption part of the picking unit.

[0025] In some embodiments, the silo 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 for the lifting member to pass through along the lifting direction of the lifting member; a plurality of the limiting members are provided on the base and are arranged at intervals around the lifting hole.

[0026] In the above technical solution, the silo is provided with a base and a plurality of limiting members. By providing a lifting hole for the lifting member to pass through on the base, the lifting member can enter the silo through the lifting hole to lift the sheet material. The structure is simple and easy to implement. In addition, by providing a plurality of limiting members on the base, and the plurality of limiting members are arranged at intervals around the lifting hole, that is, the plurality of limiting members are arranged on the base at intervals along the circumference of the lifting hole, the plurality of limiting members can limit and guide the sheet material placed on the base, thereby reducing the phenomenon of the sheet material falling off or deviating when the lifting member lifts the sheet material, thereby facilitating the normal operation of the feeding equipment.

[0027] In some embodiments, the plurality of limiting members include a first limiting member and a second limiting member. Along the first direction, the first limiting members are provided on both sides of the lifting hole. Along the second direction, the second limiting members are provided on both sides of the lifting hole. The first direction, the second direction and the lifting direction of the lifting members are perpendicular to each other.

[0028] In the above technical solution, the multiple limiting members include a first limiting member located on both sides of the lifting hole in the first direction and a second limiting member located on both sides of the lifting hole in the second direction, so that the multiple limiting members can play a limiting role on both sides of the sheet material in the first direction and the second direction, thereby helping to further enhance the limiting and guiding effects of the multiple limiting members on the sheet material, so as to further alleviate the phenomenon of the sheet material falling off or deviating when the lifting member lifts the sheet material.

[0029] In some embodiments, the first limiting member located on at least one side of the lifting hole is adjustably arranged on the base along the first direction; and / or the second limiting member located on at least one side of the lifting hole is adjustably arranged on the base along the second direction.

[0030] 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 adjustable in position along the first direction on the base, the limiting width of the sheet material of multiple first limiting members in the first direction can be adjusted by adjusting the position of the first limiting member in the first direction, so as to be applicable to sheets of different sizes in the first direction, thereby enabling the silo to store sheets of different sizes, which is beneficial to improving the scope of application of the silo and improving 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 adjustable in position along the second direction on the base, the limiting width of the sheet material of multiple second limiting members in the second direction can be adjusted by adjusting the position of the second limiting member in the second direction, so as to be applicable to sheets of different sizes in the second direction, thereby enabling the silo to store sheets of different sizes, which is beneficial to improving the scope of application of the silo and improving the production flexibility of the feeding equipment.

[0031] In some embodiments, a first adjustment slot is provided on the base, the first adjustment slot extends along the first direction, and a portion of the first limiting member is movably inserted into the first adjustment slot along the first direction.

[0032] In the above technical solution, a first adjustment groove extending along the first direction is provided on the base, and part of the first limiter is movably inserted into the first adjustment groove along the first direction to achieve adjustable position of the first limiter in the first direction. The silo adopting this structure can achieve continuous multi-stage adjustment of the position of the first limiter in the first direction to meet the placement requirements of sheet materials of different sizes, which is conducive to further improving the scope of application of the silo.

[0033] In some embodiments, a second adjustment groove is provided on the base, 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.

[0034] In the above technical solution, a second adjustment groove extending along the second direction is provided on the base, and part of the second limit member is movably inserted into the second adjustment groove along the second direction to achieve adjustable position of the second limit member in the second direction. The silo adopting this structure can achieve continuous multi-stage adjustment of the position of the second limit member in the second direction to meet the placement requirements of sheet materials of different sizes, which is conducive to further improving the scope of application of the silo.

[0035] In some embodiments, the silo further includes a first material dividing piece and a second material dividing piece, at least one of the first limiting pieces is provided with the first material dividing piece, and at least one of the first limiting pieces is provided with the second material dividing piece, along the lifting direction of the lifting piece, the first material dividing piece is located above the second material dividing piece, and the first material dividing piece and the second material dividing piece are both configured to separate the two stacked sheets during the process of the loading mechanism picking up the sheet materials in the silo.

[0036] In the above technical solution, the hopper is also provided with a first material dividing part and a second material dividing part, and the first material dividing part is arranged to be located above the second material dividing part in the lifting direction of the lifting part, so that when the feeding mechanism picks up the sheet material in the hopper, the sheet material can be separated twice by the first material dividing part and the second material dividing part, so as to improve the separation effect of the sheet materials stacked on each other, thereby effectively alleviating the phenomenon of material carrying when the feeding mechanism picks up the sheet material, so as to realize the single picking of the sheet material.

[0037] In some embodiments, the first material dividing member and the second material dividing member are respectively arranged on the two first limiting members.

[0038] In the above technical solution, by respectively arranging the first dividing piece and the second dividing piece on different first limiting pieces, it is convenient to assemble the first dividing piece and the second dividing piece, which is beneficial to reduce the difficulty of assembly and can effectively alleviate the interference between the first dividing piece and the second dividing piece.

[0039] In some embodiments, along the first direction, at least one group of two first limiting members arranged opposite to each other are provided with the first material dividing member, and the two first material dividing members are arranged opposite to each other, and at least one group of two first limiting members arranged opposite to each other are provided with the second material dividing member, and the two second material dividing members are arranged opposite to each other.

[0040] In the above technical solution, a group of first limiting members relatively arranged in the first direction are each provided with a first material dividing member, and the two first material dividing members are relatively arranged. Correspondingly, a group of first limiting members relatively arranged in the first direction are each provided with a second material dividing member, and the two second material dividing members are relatively arranged. Therefore, the two first material dividing members and the two second material dividing members relatively arranged can improve the material 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, so as to ensure the single picking of the sheet material.

[0041] In some embodiments, along the first direction, the distance between two oppositely disposed first dividing members is smaller than the distance between two oppositely disposed second dividing members.

[0042] In the above technical solution, by setting the spacing between the two first material dividing parts in the first direction to be smaller than the spacing between the second material dividing parts in the first direction, the first material dividing parts and the second material dividing parts have different material separation forces on the sheet materials, so that the two second material dividing parts located below the first material dividing parts can first perform a preliminary separation of the sheet materials, and then the two first material dividing parts located above the second material dividing parts can further separate the sheet materials, which is beneficial to enhance the effect of separating the two stacked sheets from each other, so as to realize the single picking of the sheet materials.

[0043] In some embodiments, the first dividing member and the second dividing member are both brushes, and the hardness of the bristles of the first dividing member is less than the hardness of the bristles of the second dividing member.

[0044] In the above technical solution, both the first and second material dividing members are brushes, which are simple in structure and convenient for separating the sheets. In addition, by setting the hardness of the bristles of the first material dividing member to be less than that of the bristles of the second material dividing member, damage to the sheets by the two first material dividing members located above the second material dividing member and with a small distance therebetween is reduced, and the material separation effect of the two first material dividing members on the sheets is improved.

[0045] In some embodiments, the picking unit further includes a connecting seat; the connecting seat is connected to the actuator, and at least one group of adsorption parts is provided on the connecting seat, each group of adsorption parts includes a plurality of the adsorption parts, and each group of adsorption parts corresponds to adsorbing one of the sheet materials in the silo.

[0046] In the above technical solution, the pickup unit is provided with a connection base connected to the actuator, and the suction element is disposed on the connection base, so that the actuator can drive the suction element to move and suction and pick up the sheets in the hopper. In addition, at least one group of suction elements is provided on the connection base, and each group of suction elements includes multiple suction elements, so that multiple suction elements can cooperate to suction sheets in a single hopper. This helps to improve the pickup unit's sheet picking stability and reduce the risk of sheets falling during the transfer and loading process.

[0047] In some embodiments, each group of adsorption members includes three non-collinear adsorption members, and at least one of the three adsorption members is adjustably disposed on the connecting seat in a direction perpendicular to the lifting direction of the lifting member.

[0048] In the above technical solution, each set of suction elements on the pickup unit's connecting base includes three non-collinear suction elements, meaning that the three suction elements collectively define a plane. This further enhances the stability and reliability of each set of suction elements in adhering to the sheet material. Furthermore, by configuring at least one of the three suction elements to be positionally adjustable on the connecting base, the distance between the three suction elements can be adjusted to accommodate the pickup requirements of sheets of varying sizes. This increases the applicability of the pickup unit and, in turn, effectively enhances the production flexibility of the loading equipment.

[0049] In some embodiments, the three adsorption parts include a first adsorption part, a second adsorption part and a third adsorption part; the first adsorption part is fixedly connected to the connecting seat; the second adsorption part is spaced apart from the first adsorption part along the first direction, and the second adsorption part is adjustably arranged on the connecting seat along the first direction; the third adsorption part is spaced apart from the first adsorption part and the second adsorption part along the second direction, and the third adsorption part is adjustably arranged on the connecting seat along the second direction, and the first direction, the second direction and the lifting direction of the lifting part are perpendicular to each other.

[0050] In the above technical solution, the three adsorbents in each group of adsorbents include a first adsorbent fixedly connected to the connecting seat, a second adsorbent whose position is adjustable along the first direction, and a third adsorbent whose position is adjustable along the second direction. By adjusting the position of the second adsorbent in the first direction and adjusting the position of the third adsorbent in the second direction, the spacing between the three adsorbents in each group of adsorbents in the first direction and the second direction can be adjusted to adapt to sheets of different sizes in the first direction and the second direction, thereby helping to further improve the applicability of the picking unit.

[0051] In some embodiments, the connection base is provided with multiple groups of adsorption components.

[0052] In the above technical solution, by arranging multiple groups of adsorption parts on the connecting seat, the picking unit can simultaneously pick up the sheets in multiple material bins, so as to load multiple sheets at the same time, which is conducive to optimizing the production rhythm of the loading equipment and improving the production efficiency of the loading equipment.

[0053] On the second aspect, an embodiment of the present application also provides a sheet material loading method, which is applicable to the above-mentioned loading equipment, and the sheet material loading method includes: driving the picking unit to move above the sheet material by the actuator; lifting the sheet material in the hopper by the lifting member so that the sheet material rests against the adsorption member, and when the adsorption pressure of the adsorption member adsorbing the sheet material reaches a preset value, the lifting member stops lifting the sheet material; transferring the sheet material adsorbed by the adsorption member to the loading position by the actuator to load the sheet material.

[0054] In the above technical solution, the sheet material loading method is to first drive the picking unit to move to the top of the sheet material in the hopper through the actuator, and then lift the sheet material through the lifting member so that the sheet material located on the upper side can be against the adsorption member, so that the adsorption member adsorbs the sheet material, and when the adsorption pressure of the adsorption member reaches a preset value, the lifting member stops lifting the sheet material, so that the adsorption member can drive the picking unit to move and load the sheet material after the adsorption of the sheet material is completed. This loading method does not require complex lifting position programming and high precision for the lifting member of the lifting mechanism. Accurate requirements can be met by simply judging whether to stop by the adsorption pressure of the adsorption part to achieve the jacking position control of the jacking part, thereby improving the accuracy of the adsorption part in picking up the sheet material, reducing the phenomenon that the sheet material cannot be picked up due to the position difference between the adsorption part and the sheet material, and can effectively reduce the manufacturing cost and program programming cost of the jacking mechanism. On the other hand, there is no need to replace the jacking part when jacking and loading sheet materials of different thicknesses, and there is no need to reprogram the jacking position of the jacking part, which is beneficial to improving the application range and production flexibility of the loading equipment, and making the loading equipment have higher compatibility.

[0055] In some embodiments, before the sheet material in the hopper is lifted by the lifting member so that the sheet material abuts against the adsorption member, the sheet material loading method further includes: opening the adsorption member so that the adsorption member absorbs air.

[0056] In the above technical solution, the adsorption part is opened before the lifting part lifts the sheet material to allow the adsorption part to absorb air, so that the adsorption part can adsorb the sheet material when the lifting part lifts the sheet material until it rests on the adsorption part, so that the adsorption part can adsorb the sheet material while the lifting part lifts the sheet material, which is beneficial to reduce the lifting stroke of the sheet material by the lifting part and helps to reduce the difficulty of program control of the feeding equipment.

It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0083] The term "plurality" used in this application refers to two or more (including two).

[0084] Automated manufacturing production lines often involve loading and assembling lightweight, thin sheets. For example, in automated battery production lines, thermal insulation pads, insulating pads, pole pieces, or connectors are loaded and assembled. These sheets are thin and, during storage or transportation, are typically stacked in groups. Therefore, during the loading and assembly process, it is necessary to pick up a single sheet from the stack for single loading to enable subsequent manufacturing or assembly.

[0085] The inventors have discovered that due to the difficulty of automated sheet loading, manual loading is currently the norm. This results in high labor intensity and low work efficiency during the sheet assembly process, which is detrimental to improving sheet loading efficiency and assembly costs. In order to improve sheet loading efficiency and reduce manufacturing costs, a silo is typically provided for storing multiple sheets, and a lifting mechanism is used to lift the sheets in the silo, thereby lifting the top sheet to a designated position. A gripper is then used to grab the sheet at the designated position, thereby achieving automated sheet loading. However, in a sheet material loading production line of this structure, on the one hand, it is necessary to set up more complex multiple position programming points for the jacking mechanism, and the manufacturing precision of the jacking mechanism is high, so as to improve the accuracy of the gripper in grabbing the sheet material, resulting in higher costs for loading and assembly of the sheet material. On the other hand, when replacing different types of sheet materials for loading and assembly, for example, after replacing sheets of different thicknesses, it is necessary to re-set multiple position programming points for the lifting process of the jacking mechanism, resulting in poor compatibility of automatic sheet material loading, which is not conducive to improving the production flexibility of automatic sheet material loading and assembly.

[0086] Based on the above considerations, in order to solve the problem of high cost and low compatibility of automatic loading of sheet materials, the inventors have designed a loading device after in-depth research. The loading device includes a frame, a feeding mechanism, a lifting mechanism, a loading mechanism and a detection unit. The feeding mechanism is arranged on the frame, and the feeding mechanism includes a hopper, and the hopper is used to place multiple stacked sheets. The lifting mechanism is arranged on the frame, and the lifting mechanism includes a lifting member, and the lifting member is configured to lift the sheet materials in the hopper. The loading mechanism includes a picking unit and an actuator, and the picking unit includes an adsorption member. The picking unit is connected to the actuator, and the actuator is configured to drive the picking unit to move so that the adsorption member picks up the sheet materials. The detection unit is used to detect the adsorption pressure of the adsorption member on the sheet materials, and the lifting mechanism is configured to stop lifting the sheet materials when the adsorption pressure reaches a preset value.

[0087] In the loading equipment of this structure, the lifting parts of the lifting mechanism can lift multiple sheets in the hopper, so that the sheet located on the uppermost side of the multiple sheets can be against the adsorption part of the picking unit, so that the adsorption part can adsorb and pick up the sheet, and the adsorption pressure of the adsorption part on the sheet is detected by the detection unit, so that when the adsorption pressure of the adsorption part reaches a preset value, the lifting parts of the lifting mechanism can respond to the detection unit and stop lifting the sheet to keep the sheet still, thereby facilitating the transfer and loading of the sheet after the adsorption part picks up the sheet, so as to improve the loading efficiency of the sheet. The loading equipment adopting this structure does not need to set complex lifting position programming and high precision for the lifting parts of the lifting mechanism. In order to meet the standard requirements, the lifting position of the lifting part can be controlled by judging whether the lifting part stops lifting through the adsorption pressure of the adsorption part, so as to realize the automatic loading of the sheet material, thereby improving the accuracy of the adsorption part in picking up the sheet material, so as to reduce the phenomenon that the sheet material cannot be picked up due to the position difference between the adsorption part and the sheet material, and can effectively reduce the manufacturing cost and program programming cost of the lifting mechanism, so as to reduce the automatic assembly cost of the sheet material. On the other hand, when lifting and loading sheet materials of different thicknesses, there is no need to replace the lifting part, nor to reprogram the lifting position of the lifting part, which is beneficial to improving the application range and production flexibility of the feeding equipment, and making the feeding equipment have higher compatibility.

[0088] An embodiment of the present application provides a loading device, which can improve the problem that complex program programming is required for automatic loading of sheet materials in the production line, and the program needs to be re-set after replacing sheets of different thicknesses, thereby resulting in high cost and low compatibility of automatic loading of sheet materials. The specific structure of the loading equipment is described in detail below with reference to the accompanying drawings.

[0089] According to some embodiments of the present application, please refer to Figures 1, 2 and 3. Figure 1 is a schematic block diagram of a loading device 100 provided in some embodiments of the present application, Figure 2 is a structural schematic diagram of a loading device 100 provided in some embodiments of the present application, and Figure 3 is a front view of a loading device 100 provided in some embodiments of the present application. An embodiment of the present application provides a loading device 100, which includes a frame 10, a feeding mechanism 20, a lifting mechanism 30, a loading mechanism 40 and a detection unit 50. The feeding mechanism 20 is arranged on the frame 10, and the feeding mechanism 20 includes a silo 21, and the silo 21 is used to place a plurality of stacked sheets 60. The lifting mechanism 30 is arranged on the frame 10, and the lifting mechanism 30 includes a lifting member 31, and the lifting member 31 is configured to lift the sheet 60 in the silo 21. The loading mechanism 40 includes a pickup unit 41 and an actuator 42. The pickup unit 41 includes a suction member 411. The pickup unit 41 is connected to the actuator 42. The actuator 42 is configured to drive the pickup unit 41 to move so that the suction member 411 picks up the sheet 60. The detection unit 50 is used to detect the suction pressure of the suction member 411 on the sheet 60. The lifting member 31 is configured to stop lifting the sheet 60 when the suction pressure reaches a preset value.

[0090] The silo 21 serves to store a plurality of stacked sheets 60 , that is, the plurality of sheets 60 are stacked in the silo 21 along their thickness direction, so that the loading mechanism 40 can pick up the sheets 60 .

[0091] The lifting member 31 serves to lift the sheet material 60 in the hopper 21. The structure of the lifting member 31 can be various. For example, the lifting member 31 can be an electric push rod, a cylinder, or other structures. Of course, the lifting member 31 can also 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 member is consistent with the thickness direction of the sheet material 60. The lifting direction X of the lifting member can be vertical or approximately vertical. In other words, the lifting direction X of the lifting member can be set at an angle to the vertical direction.

[0092] The pickup unit 41 is provided with a suction member 411 , which serves to suction the sheet material 60 so as to enable the pickup unit 41 to grasp the sheet material 60 . The suction member 411 may be a suction cup or the like.

[0093] The actuator 42 drives the picking unit 41 to move so as to pick up and load the sheet 60. The actuator 42 can be a three-axis gantry, a four-axis manipulator, or a six-axis manipulator. For example, in FIG2 , the actuator 42 is a six-axis manipulator.

[0094] The detection unit 50 is installed on the picking unit 41 of the feeding mechanism 40. The detection unit 50 plays the role of detecting the adsorption pressure of the adsorption component 411 on the sheet material 60, that is, the detection unit 50 can detect the adsorption negative pressure of the adsorption component 411 so that the lifting component 31 of the lifting mechanism 30 can respond to the detection result of the detection unit 50. Exemplarily, the detection unit 50 can be an air pressure sensor, etc.

[0095] 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 rest against the adsorption member 411, the adsorption member 411 can adsorb the sheet material 60, and at this time the lifting member 31 can continue to 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, thereby stopping lifting the sheet material 60 to complete the picking up of the sheet material 60 by the picking unit 41.

[0096] The lifting member 31 of the lifting mechanism 30 can lift the multiple sheets 60 in the hopper 21, so that the sheet 60 located on the uppermost side among the multiple sheets 60 can be against the adsorption member 411 of the picking unit 41, so that the adsorption member 411 can adsorb and pick up the sheet 60, and the adsorption pressure of the adsorption member 411 on the sheet 60 is detected by the detection unit 50, so that when the adsorption pressure of the adsorption member 411 reaches a preset value, the lifting member 31 of the lifting mechanism 30 can respond to the detection unit 50 and stop lifting the sheet 60 to keep the sheet 60 stationary, thereby facilitating the transfer and loading of the sheet 60 after the adsorption member 411 picks up the sheet 60, so as to improve the loading efficiency of the sheet 60. The loading equipment 100 with this structure does not need to set complex lifting position programming and For higher precision requirements, the lifting position of the lifting member 31 can be controlled by judging whether the lifting member 31 stops lifting through the adsorption pressure of the adsorption member 411, so as to realize the automatic loading of the sheet 60, thereby improving the accuracy of the adsorption member 411 in picking up the sheet 60, so as to reduce the phenomenon that the sheet 60 cannot be picked up due to the position difference between the adsorption member 411 and the sheet 60, and can effectively reduce the manufacturing cost and program programming cost of the lifting mechanism 30, so as to reduce the automatic assembly cost of the sheet 60. On the other hand, when lifting and loading sheets 60 of different thicknesses, there is no need to replace the lifting member 31, nor is there any need to reprogram the lifting position of the lifting member 31, which is beneficial to improving the scope of application and production flexibility of the loading equipment 100, so that the loading equipment 100 has higher compatibility.

[0097] According to some embodiments of the present application, referring to Figures 2 and 3, and further referring to Figures 4 and 5, Figure 4 is a schematic diagram of a partial structure of a feeding device 100 provided in some embodiments of the present application, and Figure 5 is a front view of a partial structure of the feeding device 100 provided in some embodiments of the present application. The feeding mechanism 20 further includes a movable frame 22 and a first driving member 23. The movable frame 22 is movably disposed on the frame 10 along a first direction Y. The 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 retrieval 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 driving member 23 is connected to the frame 10 and the movable frame 22. The first driving member 23 is configured to drive the movable frame 22 to switch between the loading position M and the retrieval position N.

[0098] The movable frame 22 is movably mounted on the frame 10 along a first direction Y. That is, the movable frame 22 is movable relative to the frame 10 in the first direction Y, such that the movable frame 22 has a loading position M and a retrieving position N in the first direction Y. When the movable frame 22 is at the loading position M, a sheet material 60 can be placed into a hopper 21 mounted on the movable frame 22 to load the hopper 21. When the movable frame 22 is at the retrieving position N, the lifting member 31 can lift the sheet material 60 in the hopper 21 to enable the loading mechanism 40 to pick up the sheet material 60.

[0099] For example, in Figure 4, the loading equipment 100 is provided with two feeding mechanisms 20, and the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting part. The movable frame 22 of the upper feeding mechanism 20 of the two feeding mechanisms 20 is located at the material picking position N, and the movable frame 22 of the lower feeding mechanism 20 of the two feeding mechanisms 20 is located at the loading position M.

[0100] 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 slidably cooperate to enable the movable frame 22 to be movably provided on the frame 10 along the first direction Y. Of course, in some embodiments, the slide groove may also be provided on the frame 10, and the slider may be correspondingly provided on the movable frame 22.

[0101] It should be noted that the silo 21 provided on the movable frame 22 can be one or more. In Figure 4, a plurality of silos 21 are provided on the movable frame 22. For example, there are six silos 21, and the six silos 21 are arranged in an array on the movable frame 22. Of course, in other embodiments, there can be two, three, four or five silos 21 provided on the movable frame 22. In some embodiments, referring to Figures 6 and 7, Figure 6 is a schematic diagram of the partial structure of the loading device 100 provided in some other embodiments of the present application, and Figure 7 is a front view of the partial structure of the loading device 100 provided in some other embodiments of the present application. There can also be one silo 21 provided on the movable frame 22.

[0102] The first driving member 23 is configured to drive the movable frame 22 to switch between the loading position M and the retrieving position N. That is, the first driving member 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 retrieving position N. For example, the first driving member 23 can be an electric push rod, a cylinder, or a linear motor.

[0103] The feeding mechanism 20 is also provided with a movable frame 22 and a first driving member 23. The first driving member 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, thereby driving the material bin 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 material bin 21, so that the position for loading the material bin 21 is far away from the position for the feeding mechanism 40 to pick up the sheet material 60, which is conducive to alleviating the interference phenomenon when loading and picking up the sheet material 60, so as to reduce the safety hazards in the production process. On the other hand, there is no need to manually transport the sheet material 60 to the picking position N of the movable frame 22 to realize the assembly and subsequent loading of the sheet material 60, which is conducive to reducing labor intensity and saving labor costs.

[0104] According to some embodiments of the present application, as shown in FIG. 4 and FIG. 5 , the loading 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.

[0105] Among them, the movable frames 22 of the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting part, that is, the material bins 21 of the movable frames 22 of the two feeding mechanisms 20 are arranged at intervals in the lifting direction X of the lifting part, so that the movable frames 22 of the two feeding mechanisms 20 do not interfere with each other when moving along the first direction Y, so that when the movable frame 22 of one feeding mechanism 20 is located at the loading position M to load the sheet material 60, the movable frame 22 of the other feeding mechanism 20 can be located at the material picking position N for the picking unit 41 of the loading mechanism 40 to pick up the sheet material 60 in the material bin 21.

[0106] It should be noted that the loading device 100 includes two feeding mechanisms 20 but is not limited to two feeding mechanisms 20. For example, in FIG5 , the loading device 100 is provided with two feeding mechanisms 20 spaced apart in the lifting direction X of the lifting member. In other embodiments, the loading device 100 may also include three, four, five, or six feeding mechanisms 20 spaced apart along the lifting direction X of the lifting member.

[0107] The loading equipment 100 is provided with two feeding mechanisms 20 arranged at intervals along the lifting direction X of the lifting part, so that when the movable frame 22 of one feeding mechanism 20 is located at the loading position M for loading, the movable frame 22 of the other feeding mechanism 20 can be located at the picking position N for the loading mechanism 40 to pick up and load the sheet material 60, so that the two feeding mechanisms 20 can be switched and used in coordination, thereby realizing non-stop loading and loading of the loading equipment 100, so as to realize continuous operation of the loading equipment 100, which is beneficial to improving the start-up rate of the loading equipment 100 and improving the production efficiency of the sheet material 60.

[0108] According to some embodiments of the present application, referring to Figures 4 and 5, and further referring to Figures 8 and 9, Figure 8 is a schematic structural diagram of the lifting mechanism 30 of the loading device 100 provided in some embodiments of the present application, and Figure 9 is a front view of the lifting mechanism 30 of the loading device 100 provided in some embodiments of the present application. The lifting mechanism 30 also includes an adjustment component 32, which is connected to the frame 10 and 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 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 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.

[0109] The adjusting assembly 32 is provided on the frame 10 and connected to the lifting member 31. The adjusting assembly 32 drives the lifting member 31 to move in the lifting direction X of the lifting member, so as to adjust the position of the lifting member 31 in the height direction of the lifting member 31, thereby enabling the lifting member 31 to switch between the first lifting position and the second lifting position. The structure of the adjusting assembly 32 can be various. For example, the adjusting assembly 32 can be an electric push rod, a cylinder or a linear motor as a whole. Of course, the adjusting assembly 32 can also be a combination of a motor and a worm gear structure or a combination of a motor and a rack and pinion structure.

[0110] 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 to lift the sheet material 60 in the hopper 21 of another feeding mechanism 20 when it is 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 it is 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 satisfying the need for the two feeding mechanisms 20 to switch loading without stopping. For example, in Figure 5, the two feeding mechanisms 20 are arranged at intervals along the lifting direction X of the lifting member. When the lifting member 31 is located at the first lifting position, the lifting member 31 can lift the sheet material 60 in the hopper 21 of the upper one of the two feeding mechanisms 20; when the lifting member 31 is located at the second lifting position, the lifting member 31 can lift the sheet material 60 in the hopper 21 of the lower one of the two feeding mechanisms 20.

[0111] Optionally, the number of lifting members 31 is provided in a one-to-one correspondence with the number of silos 21 of a feeding mechanism 20. When a feeding mechanism 20 has one silo 21, there is also one lifting member 31 connected to the adjustment assembly 32. When a feeding mechanism 20 has multiple silos 21, there are also multiple lifting members 31 connected to the adjustment assembly 32. For example, in Figures 4 and 8, there are six silos 21 provided on the movable frame 22, and correspondingly, the lifting mechanism 30 is provided with six lifting members 31.

[0112] It should be noted that, in the embodiment of the present application, the loading equipment 100 includes two feeding mechanisms 20 arranged at intervals along the lifting direction X of the lifting member, and the lifting member 31 has a corresponding first lifting position and a second lifting position in the lifting direction X of the lifting member, and the adjustment component 32 can drive the lifting member 31 to switch between the first lifting position and the second lifting position. If the loading equipment 100 includes three, four, five or six feeding mechanisms 20 arranged at intervals along the lifting direction X of the lifting member, the lifting member 31 has a corresponding first lifting position, a second lifting position, a third lifting position, a fourth lifting position, a fifth lifting position or a sixth lifting position, etc. in the lifting direction X of the lifting member.

[0113] The lifting mechanism 30 is also provided with an adjusting component 32 for adjusting the height position of the lifting member 31. The adjusting 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, so that the lifting member 31 can lift the sheet material 60 in the hopper 21 of different feeding mechanisms 20 when it is in different positions, so that the lifting member 31 of the lifting mechanism 30 can lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20, and there is no 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 is beneficial to reducing the assembly difficulty and manufacturing cost of the lifting mechanism 30.

[0114] In some embodiments, as shown in Figures 8 and 9 , the adjustment assembly 32 includes a mounting seat 321 and a second driving member 322. The mounting seat 321 is movably disposed on the frame 10 along a lifting direction X of the lifting member, and the lifting member 31 is mounted on the mounting seat 321. The second driving member 322 is connected to the mounting seat 321 and is configured to drive the mounting seat 321 to move along the lifting direction X of the lifting member, thereby driving the lifting member 31 to switch between a first lifting position and a second lifting position.

[0115] Exemplarily, multiple lifting members 31 are installed on the mounting seat 321, so that the second driving member 322 can simultaneously drive multiple lifting members 31 to switch between the first lifting position and the second lifting position when driving the mounting seat 321 to move along the lifting direction X of the lifting member.

[0116] Among them, the second driving member 322 plays the role of driving the mounting seat 321 to move in the lifting direction X of the lifting member. The structure of the second driving member 322 can be various. For example, in Figure 8, the second driving member 322 is a cylinder. Of course, in other embodiments, the second driving member 322 can also be an electric push rod or a linear motor.

[0117] The adjusting component 32 is provided with a mounting seat 321 and a second driving member 322, and the lifting member 31 is arranged on the mounting seat 321, so that the second driving member 322 can drive the mounting seat 321 to move in the lifting direction X of the lifting member, so as to drive the lifting member 31 to switch between the first lifting position and the second lifting position, thereby enabling the lifting member 31 to lift the sheet material 60 in the hopper 21 of the two feeding mechanisms 20. This structure is simple, easy to implement, and is conducive to improving the degree of automation of the feeding equipment 100.

[0118] In some embodiments, as shown in Figures 5, 8, and 9, 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 is provided with a guide hole 3231 extending in the lifting direction X of the lifting member. The second driving 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.

[0119] Among them, 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 arranged 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, so as to realize that the mounting seat 321 can stably move relative to the base 323 along the lifting direction X of the lifting member under the drive of the second driving member 322.

[0120] Optionally, the guide rod 324 connected to the mounting base 321 can be one or more. For example, in Figures 8 and 9, there are four guide rods 324 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 provided around the mounting base 321 along the circumference of the mounting base 321, which helps to further improve the stability of the mounting base 321 during movement along the lifting direction X of the lifting member. Of course, the structure of the adjustment assembly 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.

[0121] In some embodiments, the adjustment assembly 32 may further include a linear bearing 325, which is provided in a one-to-one correspondence with the guide rod 324. The linear bearing 325 is connected to the base 323, and the guide rod 324 is inserted into the linear bearing 325. The linear bearing 325 assists the guide rod 324 in moving relative to the base 323 along the lifting direction X of the lifting member through the linear bearing 325. This structure is conducive to further improving the stability and smoothness of the guide rod 324 moving along the lifting direction X of the lifting member. The specific structure of the linear bearing 325 can be found in the relevant art and will not be repeated here.

[0122] The adjusting 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 movably inserting the guide rod 324 into the guide hole 3231 along the lifting direction X of the lifting member, the guide rod 324 can guide the mounting seat 321 when the second driving member 322 drives the mounting seat 321 to move along the lifting direction X of the lifting member, so as to improve the stability of the mounting seat 321 when it moves along the lifting direction X of the lifting member.

[0123] According to some embodiments of the present application, as shown in Figures 4 and 8 , the lifting mechanism 30 further includes a first detection member 33, which is mounted on the lifting member 31, and the first detection member 33 is disposed in a one-to-one correspondence with the lifting member 31. The first detection member 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 member 31 is configured to reset and detach from the hopper 21 based on the first signal.

[0124] The first detecting member 33 is used to detect whether there is still sheet material 60 in the hopper 21, so that the lifting member 31 can respond to the detection result of the first detecting member 33. For example, the first detecting member 33 can have various structures, such as a pressure sensor, a light sensor, or a contact sensor.

[0125] The first detection members 33 are provided in a one-to-one correspondence with the lifting members 31 , that is, each lifting member 31 is correspondingly provided with a first detection member 33 .

[0126] In some embodiments, referring to FIG10 , FIG10 is a schematic structural diagram of the silo 21 of the feeding mechanism 20 of the loading device 100 provided in some embodiments of the present application. The silo 21 includes a base 211, which is used to place a plurality of stacked sheets 60. The base 211 is provided with lifting holes 2111 that pass through both sides of the base 211 along the lifting direction X of the lifting member. The lifting member 31 can be inserted into the lifting holes 2111 to lift the sheet 60 set on the base 211. When the first detection member 33 detects that there is no sheet 60 on the base 211, the lifting member 31 can exit from the lifting hole 2111 and reset in response to the first signal of the first detection member 33, thereby achieving the detachment of the lifting member 31 from the silo 21.

[0127] The lifting mechanism 30 is also provided with a first detection member 33, which is installed on the lifting member 31. The first detection member 33 can detect whether there is any sheet material 60 in the hopper 21, so that the lifting member 31 can respond to the first detection member 33 and exit and reset from the hopper 21 when there is no sheet material 60 in the hopper 21, thereby facilitating the first driving member 23 to drive the movable member to switch between the loading position M and the material taking position N, so as to reduce the interference effect of the lifting member 31 on the hopper 21, and no manual participation is required, which is conducive to improving the degree of automation of the loading equipment 100 to improve production efficiency.

[0128] In some embodiments, please continue to refer to Figures 4, 8 and 10, the jacking mechanism 30 may further include a second detection member 34, which is mounted on the jacking member 31, and the second detection member 34 is arranged in a one-to-one correspondence with the jacking member 31. The second detection member 34 is configured to detect the reset state of the jacking member 31 and generate a second signal indicating the reset of the jacking member 31. The adjustment component 32 is configured to adjust the height position of the jacking member 31 in the jacking direction X of the jacking member according to the second signal, and the first driving member 23 is configured to drive the movable frame 22 to switch between the loading position M and the retrieving position N according to the second signal.

[0129] Among them, the second detection member 34 plays the role of detecting whether the lifting member 31 is reset, that is, it is used to detect whether the lifting member 31 exits and disengages from the hopper 21, so that the first drive member 23 and the adjustment component 32 can respond to the detection result of the second detection member 34. That is, after the second detection member 34 detects that the lifting member 31 exits and resets from the lifting hole 2111 of the base 211 of the hopper 21, the adjustment component 32 and the first drive member 23 can both respond to the second signal of the second detection member 34, so that the adjustment component 32 can drive the lifting member 31 to move in the lifting direction X of the lifting member to adjust the height position of the lifting member 31 in the lifting direction X of the lifting member, and enable the first drive member 23 to drive the movable frame 22 to move between the loading position M and the material taking position N.

[0130] For example, the second detecting element 34 may have various structures, such as an ultrasonic distance sensor, an infrared travel sensor, or a contact sensor.

[0131] The second detecting members 34 are provided in a one-to-one correspondence with the lifting members 31 , that is, each lifting member 31 is correspondingly provided with a second detecting member 34 .

[0132] The lifting mechanism 30 is also provided with a second detection member 34, and the second detection member 34 is installed on the lifting member 31. The reset state of the lifting member 31 can be detected by the second detection member 34, so that the adjustment component 32 of the lifting mechanism 30 drives the lifting member 31 to switch between the first lifting position and the second lifting position in response to the second detection member 34, and the first driving member 23 drives the movable frame 22 to switch between the loading position M and the material taking position N in response to the second detection member 34, so that the loading equipment 100 can switch the two feeding mechanisms 20 without stopping, without manual participation, which is beneficial to improving the degree of automation of the loading equipment 100 and improving production efficiency.

[0133] According to some embodiments of the present application, as shown in FIG. 4 and FIG. 8 , the feeding mechanism 20 includes a plurality of silos 21 , and the plurality of silos 21 are all mounted on a movable frame 22 , and the silos 21 are arranged in one-to-one correspondence with the lifting members 31 .

[0134] The silos 21 and the lifting members 31 are arranged in a one-to-one correspondence, that is, each silo 21 of a feeding mechanism 20 is correspondingly provided with a lifting member 31 .

[0135] For example, in Figures 4 and 5 , six silos 21 are provided on the movable frame 22 of each feeding mechanism 20. Correspondingly, in Figure 8 , six lifting members 31 are provided on the mounting base 321 of the adjustment assembly 32 of the lifting mechanism 30. Of course, in other embodiments, the number of silos 21 provided on the movable frame 22 of each feeding mechanism 20 may also be two, three, four, or five.

[0136] By arranging multiple silos 21 on the movable frame 22 of the feeding mechanism 20, and the lifting parts 31 of the lifting mechanism 30 are arranged one-to-one corresponding to the silos 21 of each feeding mechanism 20, the feeding mechanism 20 can move the sheet materials 60 placed in the multiple silos 21 to the material picking position N for loading, which is beneficial to optimizing the production rhythm of the loading equipment 100 and improving the production efficiency of the loading equipment 100.

[0137] According to some embodiments of the present application, as shown in Figures 8, 9, and 10, the lifting member 31 includes a self-locking cylinder 311. The self-locking cylinder 311 is configured to self-lock when the adsorption pressure of the adsorption member 411 reaches a preset value to stop lifting the sheet 60. The specific structure of the self-locking cylinder 311 can be found in related art and will not be repeated here.

[0138] Among them, the self-locking cylinder 311 is installed on the mounting seat 321 of the adjusting assembly 32, so that the second driving member 322 can drive the self-locking cylinder 311 to switch between the first lifting position and the second lifting position when driving the mounting seat 321 to move along the lifting direction X of the lifting member.

[0139] In some embodiments, the lifting member 31 may further include a lifting block 312 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 silo 21 and lift the sheet 60 placed on the base 211, thereby enabling the lifting member 31 to lift the sheet 60 in the silo 21. Of course, the structure of the lifting member 31 is not limited to this. In other embodiments, the lifting member 31 can also be an electric push rod or a linear motor.

[0140] The lifting member 31 is provided with a self-locking cylinder 311, so that the sheet material 60 in the hopper 21 can be lifted by the self-locking cylinder 311, and the self-locking cylinder 311 can respond to the detection unit 50 to self-lock when the adsorption pressure of the adsorption member 411 reaches a preset value, so that the lifting member 31 stops lifting the sheet material 60. On the one hand, the lifting member 31 of this structure 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 place, so as to improve the stability and reliability of the adsorption and picking up of the sheet material 60 by the adsorption member 411 of the picking unit 41.

[0141] According to some embodiments of the present application, referring to FIG. 10 and further referring to FIG. 11 , FIG. 11 is a top view of the hopper 21 of the feeding mechanism 20 of the loading device 100 provided in some embodiments of the present application. The hopper 21 includes a base 211 and a plurality of stoppers 212 . The base 211 is used to hold the sheet material 60. 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 stoppers 212 are provided on the base 211 and are spaced apart around the lifting hole 2111.

[0142] The base 211 is used to place the sheet materials 60 , that is, a plurality of sheet materials 60 are stacked on the base 211 along the lifting direction X of the lifting member.

[0143] The base 211 is provided with a lifting hole 2111 for the lifting member 31 to pass through 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 respectively 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.

[0144] Multiple limiting members 212 are arranged on the base 211 and are arranged at intervals around the lifting hole 2111, that is, multiple limiting members 212 are 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.

[0145] For example, in Figures 10 and 11 , there are six limiting members 212 provided on the base 211 , and the six limiting members 212 are spaced apart along the circumference of the lifting hole 2111 , and the limiting members 212 extend along the lifting direction X of the lifting member. Of course, in other embodiments, the number of limiting members 212 provided on the base 211 may also be two, three, four, five, or seven, etc.

[0146] The silo 21 is provided with a base 211 and a plurality of limiting members 212. A lifting hole 2111 is provided on the base 211 for the lifting member 31 to pass through, so that the lifting member 31 can enter the silo 21 through the lifting hole 2111 to lift the sheet material 60. This structure is simple and easy to implement. In addition, by providing a plurality of limiting members 212 on the base 211, and the plurality of limiting members 212 are spaced around the lifting hole 2111, the plurality of limiting members 212 can limit and guide the sheet material 60 placed on the base 211, thereby reducing the possibility of the sheet material 60 falling off or deviating when the lifting member 31 lifts the sheet material 60, thereby facilitating the normal operation of the loading device 100.

[0147] According to some embodiments of the present application, please continue to refer to Figures 10 and 11, multiple limiting members 212 include a first limiting member 212a and a second limiting member 212b.

[0151] For example, in FIG11 , the plurality of limiting members 212 include two second limiting members 212 b , which are disposed opposite each other and are respectively located on both sides of the lifting hole 2111 in the second direction Z. Of course, in other embodiments, the number of second limiting members 212 b disposed on the base 211 may also be four, six, or eight.

[0152] It should be noted that the first direction Y and the second direction Z are respectively the width direction and the length direction of the base 211 . Correspondingly, the lifting direction X of the lifting member is the thickness direction of the base 211 .

[0153] The multiple limiting members 212 include a first limiting member 212a located on both sides of the lifting hole 2111 in the first direction Y and a second limiting member located on both sides of the lifting hole 2111 in the second direction Z, so that the multiple limiting members 212 can play a limiting role on both sides of the sheet material 60 in the first direction Y and the second direction Z, thereby helping to further enhance the limiting and guiding effects 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 deviating when the lifting member 31 lifts the sheet material 60.

[0154] According to some embodiments of the present application, as shown in Figures 10 and 11, a first stopper 212a located on at least one side of the lifting hole 2111 is adjustably disposed on the base 211 along the first direction Y.

[0171] It should be noted that the first material dividing member 213 and the second material dividing member 214 can be arranged on the same first limiting member 212a, or can be arranged on two different first limiting members 212a. For example, in Figure 10, the first material dividing member 213 and the second material dividing member 214 are respectively arranged on two first limiting members 212a.

[0180] For example, in Figures 10 and 11, only one group of two first limiting members 212a arranged opposite to each other are provided with a first material dividing member 213, that is, the two first limiting members 212a located on both sides of the lifting hole 2111 and arranged opposite to each other in the first direction Y are provided with a first material dividing member 213, and the two first material dividing members 213 are arranged opposite to each other along the first direction Y.

[0181] At least one group of two first limiting members 212a arranged opposite to each other are each provided with a second material dividing member 214, and the two second material dividing members 214 are arranged opposite to each other, that is, a group 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 material dividing member 214, or multiple groups 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 material dividing member 214.

[0182] For example, in Figures 10 and 11, only one group of two first limiting members 212a arranged opposite to each other are provided with a second material dividing member 214, that is, the two first limiting members 212a located on both sides of the lifting hole 2111 and arranged opposite to each other in the first direction Y are provided with a second material dividing member 214, and the two second material dividing members 214 are arranged opposite to each other along the first direction Y.

[0183] It should be noted that the two first dividing members 213 and the two second dividing members 214 can be arranged on the same group of two first position-limiting members 212a that are arranged opposite to each other in the first direction Y, or can be respectively arranged on two groups of first position-limiting members 212a, that is, the two first dividing members 213 are arranged on one group of two first position-limiting members 212a that are arranged opposite to each other in the first direction Y, and the two second dividing members 214 are arranged on another group of two first position-limiting members 212a that are arranged opposite to each other in the first direction Y. For example, in Figures 10 and 11, the two first dividing members 213 and the two second dividing members 214 are respectively arranged on the two groups of first position-limiting members 212a.

[0184] A group of first limiting members 212a arranged relative to each other in the first direction Y are each provided with a first material dividing member 213, and the two first material dividing members 213 are arranged relative to each other. Correspondingly, a group of first limiting members 212a arranged relative to each other in the first direction Y are each provided with a second material dividing member 214, and the two second material dividing members 214 are arranged relative to each other. Therefore, the two first material dividing members 213 and the two second material dividing members 214 arranged relative to each other can improve the material separation effect of the sheet material 60, so as to further alleviate the phenomenon of material carrying when the feeding mechanism 40 picks up the sheet material 60, so as to realize the single picking of the sheet material 60.

[0185] According to some embodiments of the present application, as shown in FIG. 12 and FIG. 13 , along the first direction Y, the distance between two oppositely disposed first dividing members 213 is smaller than the distance between two oppositely disposed second dividing members 214 .

[0186] Among them, the distance between the two first dividing parts 213 arranged opposite to each other is smaller than the distance between the two second dividing parts 214 arranged opposite to each other, that is, the spacing between the two first dividing parts 213 located above the second dividing part 214 in the lifting direction X of the lifting part in the first direction Y is smaller than the spacing between the two second dividing parts 214 located below the first dividing part 213 in the lifting direction X of the lifting part in the first direction Y, that is, the space between the two first dividing parts 213 for the sheet material 60 to pass through is smaller than the space between the two second dividing parts for the sheet material 60 to pass through.

[0187] By setting the spacing between the two first dividing parts 213 in the first direction Y to be smaller than the spacing between the second dividing parts 214 in the first direction Y, the first dividing parts 213 and the second dividing parts 214 have different material separation forces on the sheet material 60, so that the two second dividing parts 214 located below the first dividing parts 213 can first perform a preliminary separation of the sheet material 60, and then further separate the sheet material 60 through the two first dividing parts 213 located above the second dividing parts 214, which is beneficial to enhance the effect of separating the two stacked sheets 60 from each other, so as to realize the single picking of the sheet material 60.

[0188] In some embodiments, as shown in FIG. 13 , the first dividing member 213 and the second dividing member 214 are both brushes, and the hardness of the bristles of the first dividing member 213 is less than the hardness of the bristles of the second dividing member 214 .

[0189] The hardness of the bristles of the first dividing member 213 is smaller than that of the bristles of the second dividing member 214 , that is, the diameter of the bristles of the first dividing member 213 is smaller than that of the bristles of the second dividing member 214 .

[0190] The first material dividing piece 213 and the second material dividing piece 214 are both brushes, which have a simple structure and are convenient for separating the sheet materials 60. In addition, by setting the hardness of the bristles of the first material dividing piece 213 to be less than the hardness of the bristles of the second material dividing piece 214, the damage to the sheet materials 60 caused by the two first material dividing pieces 213 located above the second material dividing piece 214 and with a small distance therebetween is reduced, and the material separation effect of the two first material dividing pieces 213 on the sheet materials 60 is improved.

[0191] According to some embodiments of the present application, with reference to Figures 2 and 3, and further with reference to Figures 14, 15, and 16, Figure 14 is a schematic structural diagram of the pickup unit 41 of the loading mechanism 40 of the loading device 100 provided in some embodiments of the present application, Figure 15 is a bottom view of the pickup unit 41 of the loading mechanism 40 of the loading device 100 provided in some embodiments of the present application, and Figure 16 is an axial side view of the pickup unit 41 of the loading mechanism 40 of the loading device 100 provided in some embodiments of the present application. The pickup unit 41 may further include a connecting seat 412, the connecting seat 412 being connected to the actuator 42, and at least one group of adsorption members 411 being provided on the connecting seat 412, each group of adsorption members 411 including a plurality of adsorption members 411, and each group of adsorption members 411 corresponding to adsorbing a sheet material 60 in a hopper 21.

[0192] The connecting seat 412 has a connecting portion 4121 , and the connecting portion 4121 is used to be connected to the output end of the actuator 42 so that the actuator 42 can drive the connecting seat 412 to move.

[0193] At least one set of adsorption members 411 is provided on the connecting seat 412, that is, the pickup unit 41 may be provided with only one set of adsorption members 411 on the connecting seat 412, or may be provided with multiple sets of adsorption members 411 on the connecting seat 412. For example, in Figures 4 and 5, six silos 21 are provided on the movable frame 22 of each feeding mechanism 20. Correspondingly, in Figure 16, the pickup unit 41 includes six sets of adsorption members 411, all of which are provided on the connecting seat 412, and each set of adsorption members 411 is used to adsorb the sheet material 60 in one silo 21. Of course, in other embodiments, the pickup unit 41 may also be provided with two, three, four, five, or seven sets of adsorption members 411.

[0194] Each set of adsorbents 411 includes multiple adsorbents 411, and each set of adsorbents 411 is configured to adsorb one sheet 60 within the hopper 21. That is, each set of adsorbents 411 is composed of multiple adsorbents 411, so that the multiple adsorbents 411 in each set of adsorbents 411 cooperate to adsorb one sheet 60. For example, in Figures 15 and 16, each set of adsorbents 411 includes three adsorbents 411, so that the three adsorbents 411 cooperate to adsorb one sheet 60. Of course, in other embodiments, the number of adsorbents 411 in each set of adsorbents 411 may also be two, four, or five, etc.

[0195] For example, the adsorption member 411 is a suction cup. It should be noted that each adsorption member 411 may be provided with one or more suction cups. For example, in the embodiment of the present application, each adsorption member 411 is provided with two suction cups.

[0196] The pickup unit 41 is provided with a connection base 412 connected to the actuator 42, and the suction member 411 is disposed on the connection base 412, so that the actuator 42 can drive the suction member 411 to move and suction and pick up the sheet 60 in the hopper 21. In addition, at least one group of suction members 411 is disposed on the connection base 412, and each group of suction members 411 includes multiple suction members 411, so that multiple suction members 411 can cooperate to suction the sheet 60 in a single hopper 21. This helps improve the pickup unit 41's picking stability of the sheet 60 and reduces the risk of the sheet 60 falling off during the transfer and loading process.

[0197] According to some embodiments of the present application, please refer to Figures 14, 15 and 16, each group of adsorption members 411 includes three non-collinear adsorption members 411, and at least one of the three adsorption members 411 is adjustably arranged on the connecting seat 412 in a direction perpendicular to the lifting direction X of the lifting member.

[0198] Each group of adsorption members 411 includes three adsorption members 411 that are not collinear. That is, each group of adsorption members 411 is provided with three adsorption members 411 , and the three adsorption members 411 are not collinear, that is, the three adsorption members 411 jointly define a plane.

[0199] At least one of the three adsorption parts 411 is adjustably arranged on the connecting seat 412 in a direction perpendicular to the lifting direction X of the lifting part. That is to say, in the direction perpendicular to the lifting direction X of the lifting part, one of the three adsorption parts 411 can be adjustably arranged on the connecting seat 412, or two adsorption parts 411 can be adjustably arranged on the connecting seat 412, or all three adsorption parts 411 can be adjustably arranged on the connecting seat 412.

[0200] Each set of suction members 411 on the connection base 412 of the pickup unit 41 includes three non-collinear suction members 411, which further improves the stability and reliability of each set of suction members 411 in adsorbing the sheet 60. Furthermore, by configuring at least one of the three suction members 411 to be positionally adjustable on the connection base 412, the distance between the three suction members 411 can be adjusted to accommodate the need to pick up sheets 60 of varying sizes. This helps expand the applicability of the pickup unit 41 and, in turn, effectively enhances the production flexibility of the loading device 100.

[0201] In some embodiments, referring to Figures 15 and 16, the three adsorption members 411 include a first adsorption member 411a, a second adsorption member 411b, and a third adsorption member 411c.

The first direction Y, the second direction Z, and the lifting direction X of the lifting member are perpendicular to each other.

[0202] Among them, the second adsorption component 411b is arranged at intervals with the first adsorption component 411a along the first direction Y, and the second adsorption component 411b is adjustably arranged on the connecting seat 412 along the first direction Y, that is, the second adsorption component 411b is arranged at intervals with the first adsorption component 411a in the first direction Y, and can be adjusted in position relative to the first adsorption component 411a in the first direction Y, so that the distance between the second adsorption component 411b and the first adsorption component 411a in the first direction Y can be adjusted to adapt to the sheet materials 60 of different sizes in the first direction Y.

[0203] Exemplarily, a first movable groove 4122 extending along the first direction Y is provided on the connecting seat 412, and the first movable groove 4122 is provided in a one-to-one correspondence with the second adsorption component 411b. Part of the second adsorption component 411b is movably inserted into the first movable groove 4122 along the first direction Y, so as to realize that the second adsorption component 411b is adjustably arranged on the connecting seat 412 along the first direction Y. Of course, the structure of the picking unit 41 is not limited to this. In other embodiments, the structure in which the second adsorption component 411b is adjustably arranged on the connecting seat 412 along the first direction Y can also be other structures. For example, a plurality of third adjustment holes are provided on the connecting seat 412, and the plurality of third adjustment holes are arranged at intervals along the first direction Y, and the third adjustment holes extend along the lifting direction X of the lifting component. The second adsorption component 411b has a third plug-in portion that can be inserted into the third adjustment hole. By inserting the third plug-in portion of the second adsorption component 411b into different third adjustment holes, the position adjustment of the second adsorption component 411b relative to the connecting seat 412 in the first direction Y can be achieved.

[0204] The third adsorption component 411c is spaced apart from the first adsorption component 411a and the second adsorption component 411b along the second direction Z, and the third adsorption component 411c is adjustably arranged on the connecting seat 412 along the second direction Z, that is, the third adsorption component 411c is spaced apart from the first adsorption component 411a and the second adsorption component 411b in the second direction Z, so that the first adsorption component 411a, the second adsorption component 411b and the third adsorption component 411c are not collinear, and the position of the third adsorption component 411c can be adjusted relative to the first adsorption component 411a in the second direction Z, so that the distance between the third adsorption component 411c and the first adsorption component 411a in the second direction Z can be adjusted to adapt to the sheet materials 60 of different sizes in the second direction Z.

[0205] Exemplarily, a second movable groove 4123 extending along the second direction Z is provided on the connecting seat 412, and the second movable groove 4123 is provided in a one-to-one correspondence with the third adsorption component 411c. Part of the third adsorption component 411c is movably inserted into the second movable groove 4123 along the second direction Z, so as to realize that the position of the third adsorption component 411c along the second direction Z can be adjusted on the connecting seat 412. Of course, the structure of the picking unit 41 is not limited to this. In other embodiments, the structure in which the third adsorption component 411c is adjustably arranged on the connecting seat 412 along the second direction Z may also be other structures. For example, a plurality of fourth adjustment holes are provided on the connecting seat 412, and the plurality of fourth adjustment holes are arranged at intervals along the second direction Z, and the fourth adjustment holes extend along the lifting direction X of the lifting component. The third adsorption component 411c has a fourth plug-in portion that can be plugged into the fourth adjustment hole. By plugging the fourth plug-in portion of the third adsorption component 411c into different fourth adjustment holes, the position adjustment of the third adsorption component 411c relative to the connecting seat 412 in the second direction Z can be achieved.

[0206] The three adsorbents 411 in each group of adsorbents 411 include a first adsorbent 411a fixedly connected to the connecting seat 412, a second adsorbent 411b whose position is adjustable along the first direction Y, and a third adsorbent 411c whose position is adjustable along the second direction Z. By adjusting the position of the second adsorbent 411b in the first direction Y and adjusting the position of the third adsorbent 411c in the second direction Z, the spacing between the three adsorbents 411 in each group of adsorbents 411 in the first direction Y and the second direction Z can be adjusted to adapt to sheets 60 of different sizes in the first direction Y and the second direction Z, thereby helping to further improve the applicability of the picking unit 41.

Correspondingly, in Figures 15 and 16 , the picking unit 41 includes six groups of adsorbents 411, all of which are provided on a connecting seat 412, with each group of adsorbents 411 being used to adsorb the sheet material 60 in one hopper 21. Of course, in other embodiments, two, three, four, five, or seven groups of adsorbents 411 may also be provided on the connecting seat 412.

[0209] By arranging multiple groups of adsorption parts 411 on the connecting seat 412, the picking unit 41 can simultaneously pick up the sheet materials 60 in multiple material bins 21, so as to load multiple sheet materials 60 at the same time, which is beneficial to optimize the production rhythm of the loading equipment 100 and improve the production efficiency of the loading equipment 100.

[0210] According to some embodiments of the present application, a loading device 100 is provided for loading and assembling sheet materials 60.

The self-locking cylinder 311 is connected to the frame 10 via the adjustment assembly 32. The lifting block 312 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 to lift the sheet material 60 in the hopper 21. The adjustment assembly 32 is configured to adjust the height 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 in the first lifting position, and to lift the sheet material 60 in the hopper 21 of another feeding mechanism 20 when in the second lifting position. The adjustment assembly 32 includes a mounting base 321, a second driving member 322, a base 323, and a guide rod 324. The base 323 is connected to the frame 10 and is provided with a guide hole 3231 extending along the lifting direction X of the lifting member. The second driving 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. The guide rod 324 is connected to the mounting base 321, and the self-locking cylinder 311 of the lifting member 31 is mounted on the mounting base 321. The second driving 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 driving the lifting member 31 to switch between the first lifting position and the second lifting position. The feeding mechanism 40 includes a pickup unit 41 and an actuator 42. The pickup unit 41 includes a suction member 411. The pickup unit 41 is connected to the actuator 42.

The lifting member 31 is configured to stop lifting the sheet material 60 when the adsorption pressure reaches a preset value.

[0211] According to some embodiments of the present application, a method for loading a sheet 60 is further provided, which is applicable to the loading device 100 of any of the above schemes. Referring to FIG. 1 , FIG. 2 , and FIG. 3 , and further referring to FIG. 17 , FIG. 17 is a flow chart of the method for loading a sheet 60 provided in some embodiments of the present application. The method for loading a sheet 60 includes:

[0212] S100: The picking unit 41 is driven by the actuator 42 to move to the top of the sheet 60;

[0213] S200: The lifting member 31 lifts the sheet 60 in the hopper 21 so that the sheet 60 abuts against the adsorption member 411. When the adsorption pressure of the adsorption member 411 on the sheet 60 reaches a preset value, the lifting member 31 stops lifting the sheet 60.

[0214] S300 : The sheet material 60 adsorbed by the adsorption member 411 is transferred to the loading position by the actuator 42 to load the sheet material 60 .

[0215] In the above-mentioned feeding method, the feeding method of the sheet material 60 is to first drive the picking unit 41 to move to the top of the sheet material 60 in the hopper 21 through the actuator 42, and then lift the sheet material 60 through the lifting member 31, so that the sheet material 60 located on the uppermost side can be against the adsorption member 411, so that the adsorption member 411 adsorbs the sheet material 60, and when the adsorption pressure of the adsorption member 411 reaches a preset value, the lifting member 31 stops lifting the sheet material 60, so that the adsorption member 411 completes the adsorption of the sheet material 60, and the picking unit 41 can be driven by the actuator 42 to move and feed the sheet material 60. This feeding method does not require setting a complicated lifting position for the lifting member 31 of the lifting mechanism 30. Programming and higher precision requirements, the lifting position control of the lifting member 31 can be achieved by judging whether to stop through the adsorption pressure of the adsorption member 411, thereby improving the accuracy of the adsorption member 411 in picking up the sheet material 60, so as to reduce the phenomenon that the sheet material 60 cannot be picked up due to the position difference between the adsorption member 411 and the sheet material 60, and can effectively reduce the manufacturing cost and program programming cost of the lifting mechanism 30. On the other hand, when lifting and loading sheets 60 of different thicknesses, there is no need to replace the lifting member 31, nor is there any need to reprogram the lifting position of the lifting member 31, which is beneficial to improving the scope of application and production flexibility of the loading equipment 100, so that the loading equipment 100 has higher compatibility.

[0216] According to some embodiments of the present application, referring to FIG. 18 , FIG. 18 is a flow chart illustrating a method for loading a sheet material 60 according to yet another embodiment of the present application. In step S200 , the sheet material 60 in the hopper 21 is lifted by the lifting member 31 so that the sheet material 60 abuts against the adsorption member 411 . The method for loading the sheet material 60 may further include:

[0217] S400 : Open the adsorption member 411 to allow the adsorption member 411 to absorb air.

[0218] Among them, step S400 is performed before step S200: the adsorption component 411 is opened to allow the adsorption component 411 to absorb air, that is, before the lifting component 31 lifts the sheet material 60 in the hopper 21, the adsorption component 411 is opened first to allow the adsorption component 411 to start operating first, so that when the lifting component 31 lifts the sheet material 60 to rest against the adsorption component 411, the adsorption component 411 can produce an adsorption effect on the sheet material 60.

[0219] In the above-mentioned loading method, the adsorption part 411 is opened before the lifting part 31 lifts the sheet material 60 so that the adsorption part 411 can absorb air, so that the lifting part 31 can adsorb the sheet material 60 when it lifts the sheet material 60 to rest on the adsorption part 411, so that the adsorption part 411 can adsorb the sheet material 60 while the lifting part 31 lifts the sheet material 60, which is beneficial to reduce the lifting stroke of the lifting part 31 on the sheet material 60, and is beneficial to reduce the difficulty of program control of the loading equipment 100.

[0220] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0221] The above are merely preferred embodiments of the present application and are not intended to limit the present application. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
