Description

Technical Field

[0001] This application relates to the field of automation equipment technology, and more specifically, to a feeding device and a film-tearing device. Background Technology

[0002] In automated production, materials are typically placed in trays to facilitate equipment handling, photographing, or scanning. Some trays are manufactured using vacuum forming or injection molding, featuring a concave front and a convex back. The material is placed within the concave portion of the tray, allowing it to be positioned correctly. During material transfer, multiple trays are sometimes stacked to form a complete stack, which is then transported to the loading side of the corresponding equipment.

[0003] For a stack of trays, the raised portion of the upper tray inserts into the recessed portion of the adjacent lower tray, creating a jamming effect. This can easily cause adjacent trays to become stuck together due to negative pressure or static friction. Therefore, during automated operation, when a robotic arm uses a vacuum suction cup or gripper to pick up a single tray from the top layer, it can easily move other trays that are jammed with that tray. Utility Model Content

[0004] In view of this, this application provides a feeding device and a film-tearing device, wherein the film-tearing device uses such a feeding device, which can sequentially move each of the material trays in a stack of material trays.

[0005] Embodiments of this application provide a feeding device for sequentially moving each tray in a stack of trays. The gap between the first and second trays in the stack from top to bottom is defined as the tray separation gap. The feeding device includes a receiving component, a lifting component, a material support component, and a tray separation component. The receiving component is configured to receive the entire stack of trays. The lifting component is connected to the receiving component and configured to drive the receiving component to move up and down. The material support component includes a material support member, a material support drive member, and a lifting drive member. The material support drive member is connected to the material support member and configured to drive the material support member to insert into the tray separation gap in a forward direction along a first direction. The lifting drive member is connected to the material support member and configured to drive the material support member to move up and down. The first direction intersects with the direction of the material support member's movement. The tray separation component includes a tray separation member and a tray separation drive member. The tray separation drive member is connected to the tray separation member and configured to drive the tray separation member to insert into the tray separation gap in a forward direction along a second direction. The second direction intersects with the direction of the material support member's movement.

[0006] When this feeding device operates, the entire stack of trays is placed on the receiving component. The lifting component then drives the receiving component to rise to a predetermined position. Next, the material support drive inserts the material support component into the tray separating gap, and the tray separating drive inserts the tray separating component into the tray separating gap. Finally, the lifting drive raises the material support component, causing the material support component to lift the tray above it. The tray separating component stops the tray below it, thus separating the first and second layers of trays from top to bottom, allowing the corresponding first-layer trays to be fed individually. This cycle repeats, allowing each tray in the stack to be fed individually in sequence.

[0007] In some embodiments of this application, the material support is provided with a guide surface and a reference surface on both sides along the lifting direction of the material support, and the distance between the guide surface and the reference surface gradually decreases along the positive direction of the first direction in the lifting direction of the material support.

[0008] The guide surface can reduce the size of the front end of the material support in the direction of its lifting and lowering along the first direction, thereby facilitating the insertion of the material support into the gap between the dividers.

[0009] In some embodiments of this application, the feeding device further includes a sensor, a control element, and a response element. The sensor and the response element are both electrically connected to the control element. The sensor is configured to sense the material tray on the material support element. The response element operates when the sensor senses the material tray or when the sensor does not sense the material tray.

[0010] The sensor detects whether there is a tray on the material support to determine whether the first and second trays of the stack have been successfully separated from top to bottom. The response device issues an alert or acts as a drive in the next process, thus promptly reminding the operator or pausing the next process when there is no tray on the material support.

[0011] In some embodiments of this application, the receiving component includes a receiving frame, which includes a fixed bracket, a sliding bracket, and a fixing member. The fixed bracket is connected to the lifting component, the sliding bracket is slidably connected to the fixed bracket along a third direction and is configured to receive a stack of material trays, and the fixing member is configured to fix the sliding bracket to the fixed bracket. The third direction intersects with the lifting direction of the fixed bracket.

[0012] By sliding the sliding bracket to connect with the fixed bracket, the sliding bracket can be slid to the outside of the area between the fixed bracket and the tray divider, thereby increasing the operating space for placing a stack of trays on the sliding bracket, which makes it easier to place the stack of trays.

[0013] In some embodiments of this application, the receiving component includes a receiving frame and a conveyor. The receiving frame is connected to a lifting component, and the conveyor is disposed on the receiving frame and configured to drive the entire stack of trays to move along a third direction, which intersects with the lifting direction of the receiving frame.

[0014] When placing a stack of trays on the receiving rack, the stack of trays can be conveyed to the predetermined position on the receiving rack via a conveyor, making the operation simple and quick.

[0015] In some embodiments of this application, the receiving frame is provided with a positioning element configured to stop the entire stack of trays as the entire stack of trays moves in the positive direction of a third direction.

[0016] When the conveyor transports a stack of trays, the positioning component positions the stack of trays, which can improve the conveying accuracy of the conveyor transporting the stack of trays.

[0017] Embodiments of this application also provide a film-tearing device, which includes a film-tearing apparatus and a feeding device provided in any of the above embodiments. The film-tearing apparatus is configured to tear off the film on the material tray on the material support of the feeding device.

[0018] The feeding device is used to automatically feed the film-tearing device, which can improve the feeding speed of the film-tearing device and thus improve the film-tearing efficiency of the film-tearing device.

[0019] In some embodiments of this application, the film-tearing device further includes a positioning platform and a positioning drive, the positioning drive being connected to the positioning platform and configured to drive the positioning platform to move below the material support, and the positioning platform being configured to support the material tray on the material support.

[0020] The positioning platform is used to support the material tray, which can keep the material in the tray in a stable position after being pressed, so as to facilitate the film tearing operation and thus improve the accuracy of the film tearing operation.

[0021] In some embodiments of this application, the film-tearing device further includes a positioning device, which includes clamping components disposed on opposite sides of the positioning platform, the two clamping components being configured to abut against opposite sides of the material tray respectively.

[0022] By placing two clamping components against opposite sides of the tray, the tray can be constrained in the distribution direction of the two clamping components, so that the position of the tray remains fixed during the film-tearing operation, thereby improving the film-tearing accuracy.

[0023] In some embodiments of this application, the film-tearing device includes a pressing assembly and a film-tearing assembly. The pressing assembly is configured to press the material in the material tray. The film-tearing assembly includes a film-tearing drive, a vacuum suction head, grippers, and a clamping drive. The vacuum suction head is disposed on the film-tearing drive and configured to adsorb the film on the material in the material tray. The clamping drive is disposed on the film-tearing drive and connected to the grippers. The clamping drive is configured to drive the grippers to move toward the vacuum suction head to press the film against the vacuum suction head.

[0024] During the film-tearing operation, the pressing assembly first presses the material in the tray. Then, the film-tearing drive drives the vacuum suction head to approach the film on the material. After the vacuum suction head adsorbs the film, the clamping drive drives the gripper to move, so that the gripper moves toward the vacuum suction head and presses the film against the vacuum suction head, so that the film is fixed to the vacuum suction head. Finally, the film-tearing drive drives the vacuum suction head away from the material, so that the film is separated from the material. Attached Figure Description

Detailed Implementation

[0036] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0038] The terms “first,” “second,” “third,” etc., used in this article are for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0039] Embodiments of this application provide a feeding device for sequentially moving each tray in a stack of trays. The gap between the first and second trays in the stack from top to bottom is defined as the tray separation gap. The feeding device includes a receiving component, a lifting component, a material support component, and a tray separation component. The receiving component is configured to receive the entire stack of trays. The lifting component is connected to the receiving component and configured to drive the receiving component to move up and down. The material support component includes a material support member, a material support drive member, and a lifting drive member. The material support drive member is connected to the material support member and configured to drive the material support member to insert into the tray separation gap in a forward direction along a first direction. The lifting drive member is connected to the material support member and configured to drive the material support member to move up and down. The first direction intersects with the direction of the material support member's movement. The tray separation component includes a tray separation member and a tray separation drive member. The tray separation drive member is connected to the tray separation member and configured to drive the tray separation member to insert into the tray separation gap in a forward direction along a second direction. The second direction intersects with the direction of the material support member's movement.

[0040] When this feeding device operates, the entire stack of trays is placed on the receiving component. The lifting component then drives the receiving component to rise to a predetermined position. Next, the material support drive inserts the material support component into the tray separation gap, and the tray separation drive inserts the tray separation component into the tray separation gap. Finally, the lifting drive drives the material support component to rise, causing the material support component to lift the tray above it. The tray separation component stops the second layer of trays located below it, thus separating the first and second layer of trays from top to bottom, allowing the corresponding first layer of trays to be fed individually. This cycle repeats, allowing each tray in the stack to be fed individually in sequence.

[0041] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0042] Reference Figure 1 and Figure 2 One embodiment of this application provides a feeding device 100, which is used to sequentially move each of the stacked material trays 200.

[0043] In some embodiments, the feeding device 100 includes a frame 11, a receiving component 12, a lifting component 13, a material supporting component 14, and a tray separating component 15. The receiving component 12 is configured to receive a stack of trays 200; the lifting component 13 is disposed on the frame 11 and connected to the receiving component 12, and is configured to drive the receiving component 12 to move up and down; the material supporting component 14 is disposed on the frame 11 and is configured to drive the first layer of trays 21 of the stack of trays 200 from top to bottom to rise; the tray separating component 15 is disposed on the frame 11 and is configured to stop the second layer of trays 22 of the stack of trays 200 from top to bottom. It is understood that the receiving component 12 is located below the material supporting component 14 and the tray separating component 15. In other embodiments, the frame 11 may be omitted, and the lifting component 13, the tray separating component 15, and the material supporting component 14 may be disposed on the ground, a wall, or other equipment.

[0044] After the entire stack of trays 200 is placed on the receiving component 12, the lifting component 13 drives the receiving component 12 to rise, causing the first layer of trays 21 from top to bottom to move close to the material support component 14. The material support component 14 then drives the first layer of trays 21 from top to bottom to rise. At the same time, the tray separating component 15 stops the second layer of trays 22 from top to bottom, separating the first layer of trays 21 from the second layer of trays 22, allowing the corresponding first layer of trays 21 to rise independently for feeding. By repeating the above cycle, each tray of the entire stack of trays 200 can be fed individually in sequence.

[0045] Reference Figure 2 and Figure 3 In some embodiments, the gap between the first layer of trays 21 and the second layer of trays 22 from top to bottom in the stack of trays 200 is defined as the tray gap 23. In some embodiments, the direction of lifting and lowering of the receiving component 12 is defined as the lifting direction Z. In some embodiments, the lifting direction Z is parallel to the direction of gravity. It is understood that the lifting and lowering direction of other structural components in this application is parallel to the lifting direction Z. For ease of description, the lifting and lowering direction of other structural components in this application is also defined as the lifting direction Z.

[0046] In some embodiments, the frame 11 is provided with a tray-splitting station, and the material support assembly 14 and the tray-splitting assembly 15 are arranged around the tray-splitting station.

[0047] Reference Figure 3 and Figure 4In some embodiments, the material support assembly 14 includes a material support member 141 and a material support drive member 142. In some embodiments, the material support assembly 14 further includes a material support frame 143. The material support drive member 142 includes a cylinder, the cylinder body of which is fixedly connected to the material support frame 143. The material support member 141 includes an insertion portion 1411 and a connecting portion 1412. The insertion portion 1411 protrudes forward along the positive direction of the first direction X and is disposed on the connecting portion 1412. The connecting portion 1412 is connected to the piston rod of the material support drive member 142. The first direction X intersects the lifting direction Z, and the positive direction of the first direction X is oriented towards the center of the tray-separating station. Exemplarily, the first direction X is perpendicular to the lifting direction Z.

[0048] After the first and second trays 21 and 22 of the stack of trays 200 rise to the tray separating station from top to bottom, the tray separating gap 23 is located at the tray separating station and aligned with the insertion part 1411 along the first direction X. The material support drive 142 drives the material support member 141 to move in the positive direction along the first direction X, so that the insertion part 1411 is inserted into the tray separating gap 23. In some embodiments, the connecting part 1412 may be omitted, and the insertion part 1411 is connected to the piston rod of the material support drive 142.

[0049] In other embodiments, the material support drive 142 may also be a lead screw and nut structure, a linear motor, or other structural components capable of driving the material support 141 to move.

[0050] The material support assembly 14 also includes a lifting drive 144. In some embodiments, the lifting drive 144 is a cylinder, with its cylinder body connected to the frame 11 and its piston rod connected to the material support frame 143. After the insertion part 1411 is inserted into the tray gap 23, the lifting drive 144 drives the material support frame 143 to rise, causing the insertion part 1411 to lift the corresponding first layer tray 21. In other embodiments, the material support frame 143 may be omitted, and the cylinder body of the material support drive 142 is connected to the piston rod of the lifting drive 144, enabling the lifting drive 144 to drive the material support drive 142 to rise and fall, thereby causing the material support 141 to rise and fall.

[0051] In other embodiments, the lifting drive 144 may also be a lead screw and nut structure, a linear motor, or other structural components capable of driving the material support frame 143 to lift.

[0052] Reference Figure 3 and Figure 4In some embodiments, the material support 141 is provided with a guide surface 1411a and a reference surface 1411b on both sides along the lifting direction Z. It can be understood that the insertion part 1411 is provided with a guide surface 1411a and a reference surface 1411b on both sides along the lifting direction Z. In some embodiments, the reference surface 1411b is parallel to the first direction X, the guide surface 1411a is inclined relative to the first direction X, and the distance between the guide surface 1411a and the reference surface 1411b gradually decreases along the positive direction of the first direction X in the lifting direction Z. The guide surface 1411a can reduce the size of the front end of the material support 141 in the positive direction of the first direction X in the lifting direction Z, thereby facilitating the insertion of the material support 141 into the tray gap 23. In other embodiments, the reference surface 1411b can also be inclined relative to the first direction X, as long as the distance between the guide surface 1411a and the reference surface 1411b gradually decreases along the positive direction of the first direction X in the lifting direction Z.

[0053] Reference Figure 1 and Figure 2 The tray-separating assembly 15 includes a tray-separating component 151 and a tray-separating drive component 152. In some embodiments, the tray-separating drive component 152 is a cylinder, the cylinder body of which is connected to the frame 11. The tray-separating component 151 is generally plate-shaped and connected to the piston rod of the tray-separating drive component 152. The tray-separating drive component 152 is configured to drive the tray-separating component 151 into the tray-separating gap 23 in a positive direction along a second direction Y, which intersects the lifting direction Z. Exemplarily, the second direction Y is perpendicular to the lifting direction Z and perpendicular to the first direction X, with the positive direction of the second direction Y oriented towards the center of the tray-separating station. In other embodiments, the second direction Y may be parallel to the first direction X. After the partition drive 152 drives the partition component 151 to be inserted into the partition gap 23, the partition component 151 can stop the second layer of material trays 22 from top to bottom of the stack of material trays 200, thereby separating the second layer of material trays 22 from the first layer of material trays 21, so that the first layer of material trays 21 can be fed alone.

[0054] In other embodiments, the distributor drive 152 may also be a lead screw and nut structure, a linear motor, or other structural components capable of driving the distributor 151 to move.

[0055] In some embodiments, two tray-separating assemblies 15 and two material-supporting assemblies 14 are provided. The two tray-separating assemblies 15 are disposed opposite each other on both sides of the tray-separating station along the second direction Y, and the two material-supporting assemblies 14 are disposed opposite each other on both sides of the tray-separating station along the first direction X. It is understood that each material-supporting drive member 142 is configured to drive the corresponding material-supporting member 141 to move toward the center direction of the tray-separating station, so that the corresponding material-supporting member 141 is inserted into the tray-separating gap 23. Each tray-separating drive member 152 is configured to drive the corresponding tray-separating member 151 to move toward the center direction of the tray-separating station, so that the corresponding tray-separating member 151 is inserted into the tray-separating gap 23.

[0056] In some embodiments, after the material support drive 142 drives the material support member 141 to insert into the tray divider gap 23, the tray divider drive 152 drives the tray divider member 151 to insert into the tray divider gap 23. In other embodiments, the material support drive 142 drives the material support member 141 to insert into the tray divider gap 23 after the tray divider drive 152 drives the tray divider member 151 to insert into the tray divider gap 23. In other embodiments, the material support drive 142 and the tray divider drive 152 can operate simultaneously.

[0057] Reference Figure 1 In some embodiments, the feeding device 100 further includes a sensor 16, a control unit (not shown), and a response unit (not shown). The sensor 16 and the response unit are both electrically connected to the control unit. The sensor 16 is configured to sense the trays (not shown) on the material support 141. The response unit activates when the sensor 16 senses a tray or when the sensor 16 does not sense a tray. It is understood that the frame 11 has a sensing station located above the tray separating station. The sensor 16 is used to detect whether there is a tray on the material support 141 to determine whether the first layer of trays 21 and the second layer of trays 22 in the stack of trays 200 have been successfully separated from top to bottom. The response unit is used to issue a warning message or act as a driving element in the next process, thereby promptly reminding the operator or pausing the next process when there is no tray on the material support 141.

[0058] Exemplarily, the sensing element 16 includes a photoelectric sensor, which is disposed at the sensing station and fixedly connected to the frame 11, and the sensing end of the sensing element 16 is oriented along the second direction Y. After the material carrier 141 rises to the sensing station, the sensing element 16 can detect whether there is a material tray on the material carrier 141. In some embodiments, the control element is a PLC. In some embodiments, the response element is an alarm light. When the material carrier 141 rises to the sensing station and the sensing element 16 does not detect a material tray, the alarm light flashes, and the flashing alarm light can remind the operator to stop the machine for inspection in time.

[0059] In other embodiments, the sensor 16 may be an ultrasonic detector or other device capable of detecting whether a tray is on the material carrier 141. In other embodiments, the control device may be a control system of the processing equipment using this feeding device 100 or other device with control functions. In other embodiments, the response device may be a buzzer or a display or other device capable of displaying warning information. In other embodiments, the response device may be a structural component in the processing equipment using this feeding device 100, such as a robotic arm unit for gripping materials or a processing unit for processing materials.

[0060] Reference Figure 1 and Figure 5In some embodiments, the feeding device 100 further includes a base 17 and a connecting frame (not shown). The base 17 is located below the frame 11, and the connecting frame is located between the base 17 and the frame 11 and fixedly connects the base 17 and the frame 11. The lifting assembly 13 includes a base 131, a lifting seat 132, and a lifting drive structure 133. The base 131 is fixedly connected to the base 17, the lifting seat 132 is slidably connected to the base 131, and the lifting drive structure 133 is disposed on the base 131 and connected to the lifting seat 132. The lifting drive structure 133 is configured to drive the lifting seat 132 to lift. It is understood that the lifting seat 132 is slidably connected to the base 131 along the lifting direction Z. In other embodiments, the base 17 and the connecting frame may be omitted, and the base 131 of the lifting assembly 13 is connected to the frame 11 or the ground.

[0061] In some embodiments, the lifting drive structure 133 is a lead screw and nut structure. The lead screw is rotatably connected to the base 131 and driven to rotate by a motor. The lifting seat 132 is connected to the nut. The motor drives the lead screw to rotate, which in turn causes the nut to lift the lifting seat 132. In other embodiments, the lifting drive structure 133 can also be a chain drive structure. The sprocket of the chain drive structure is rotatably connected to the base 131 and driven to rotate by a motor. The lifting seat 132 is connected to the chain of the chain drive structure. The sprocket of the chain drive structure drives the chain of the chain drive structure to move, thereby causing the chain of the chain drive structure to lift the lifting seat 132. In other embodiments, the lifting drive structure 133 can also be a hydraulic cylinder or a linear motor, or other structures capable of driving the lifting seat 132 to lift.

[0062] In some embodiments, the receiving assembly 12 includes a receiving frame 121, which includes a fixed bracket 1211, a sliding bracket 1212, and a fixing member (not shown). The fixed bracket 1211 is connected to the lifting assembly 13, and the sliding bracket 1212 is slidably connected to the fixed bracket 1211 along a third direction U. The fixing member is configured to fix the sliding bracket 1212 to the fixed bracket 1211. The third direction U intersects the lifting direction of the fixed bracket 1211. Exemplarily, the third direction U is parallel to the first direction X, and the positive direction of the third direction U is the same as the positive direction of the first direction X. In other embodiments, the third direction U may be parallel to the second direction Y.

[0063] It is understood that the fixed bracket 1211 is fixedly connected to the lifting seat 132. In some embodiments, the sliding bracket 1212 is slidably connected to the fixed bracket 1211 via a slide rail. By making the sliding bracket 1212 slidably connected to the fixed bracket 1211, the sliding bracket 1212 can be slid to the outside of the area between the fixed bracket 1211 and the tray divider 151, thereby increasing the operating space for placing a stack of trays 200 on the sliding bracket 1212, thus facilitating the placement of the stack of trays 200. The fixing member is a screw, which is used to fix the sliding bracket 1212 after it moves in the positive direction U along the third direction above the fixed bracket 1211. In other embodiments, the fixing member can also be other structural components capable of fixing the sliding bracket 1212.

[0064] In some embodiments, the receiving assembly 12 further includes a conveyor 122, which is disposed on the receiving frame 121 and configured to drive the stack of trays 200 to move in a third direction U. It is understood that the conveyor 122 is connected to the sliding support 1212. When placing the stack of trays 200, the stack of trays 200 can be conveyed to a predetermined position on the sliding support 1212 via the conveyor 122, making the operation simple and quick. In other embodiments, the sliding support 1212 may be omitted, and the conveyor 122 is disposed on the fixed support 1211.

[0065] Exemplarily, the conveyor 122 is a belt conveyor. In some embodiments, two conveyors 122 are provided, spaced apart along the second direction Y on a sliding bracket 1212, and configured to respectively receive both sides of a stack of trays 200 along the second direction Y. In some embodiments, at least one conveyor 122 is movable along the second direction Y to adjust the distance between the two conveyors 122 according to the size of the stack of trays 200. Exemplarily, the conveyor 122 is slidably connected to the sliding bracket 1212 along the second direction Y via a slide rail, and after the conveyor 122 is adjusted to a predetermined position, it can be fixed to the sliding bracket 1212 by screws. In other embodiments, the conveyor 122 can also be a structure in which a movable seat driven by a screw and nut mechanism moves, the movable seat being used to receive the stack of trays 200. In other embodiments, the conveyor 122 can also be other structures capable of conveying the stack of trays 200.

[0066] In some embodiments, the receiving frame 121 is provided with a positioning member 1213, which is configured to stop the stack of trays 200 when it moves in the positive direction of the third direction U. Exemplarily, the positioning member 1213 is plate-shaped and is located at the front end of the sliding bracket 1212 in the positive direction of the third direction U and connected to the fixing frame of the conveyor 122. In other embodiments, the positioning member 1213 may also be fixedly connected to the sliding bracket 1212. When the conveyor 122 conveys the stack of trays 200 in the positive direction of the third direction U, the positioning member 1213 can abut against the front side of the stack of trays 200 in the positive direction of the third direction U to stop the stack of trays 200, at which time the stack of trays 200 moves to a predetermined position. The positioning member 1213 has a positioning function, which can improve the conveying accuracy of the conveyor 122 on the stack of trays 200.

[0067] In some embodiments, the conveyor 122 may be a single unit, as long as it is capable of receiving and conveying an entire stack of trays 200. In other embodiments, the conveyor 122 may be omitted, and the sliding bracket 1212 is used to receive the entire stack of trays 200. In still other embodiments, both the conveyor 122 and the sliding bracket 1212 may be omitted, and the fixed bracket 1211 is used to receive the entire stack of trays 200.

[0068] Reference Figure 6 and Figure 7 One embodiment of this application also provides a film-tearing device 300, which includes a film-tearing device 31 and a feeding device 100 provided in any of the above embodiments. The film-tearing device 31 is configured to tear the film 41 off the material 400 in the material tray (not shown) on the material support member 141 of the feeding device 100. The feeding device 100 is used to automatically feed the film to the film-tearing device 31, which can improve the feeding speed of the film-tearing device 31 and thus improve the film-tearing efficiency of the film-tearing device 31.

[0069] In some embodiments, the film-tearing device 300 further includes a positioning platform 32 and a positioning drive 33. The positioning drive 33 is connected to the positioning platform 32 and configured to drive the positioning platform 32 to move below the material support 141. The positioning platform 32 is configured to support the material tray on the material support 141. In some embodiments, the positioning platform 32 is slidably disposed on the frame 11 along the second direction Y, and the positioning drive 33 is a screw and nut structure. After the material support 141 moves the material tray to the sensing position, the positioning drive 33 drives the positioning platform 32 to move below the material support 141 and the material tray on the material support 141. Then, the lifting drive 144 drives the material support frame 143 to move downward, so that the material support 141 moves below the positioning platform 32, thereby causing the corresponding material tray to fall onto the positioning platform 32. The positioning platform 32 can support the corresponding material tray, and can keep the material 400 in the material tray in a stable posture after being pressed, so as to facilitate the film-tearing operation and improve the accuracy of the film-tearing operation. In other embodiments, the positioning drive 33 may be a cylinder, a linear motor, or other structural components capable of driving the positioning platform 32 to move.

[0070] In some embodiments, the film-tearing device 300 has two feeding devices 100, which are arranged sequentially along the second direction Y. During the movement of the positioning platform 32 along the second direction Y, the positioning platform 32 can sequentially move to the sensing positions of the two feeding devices 100. When the positioning platform 32 moves to the sensing position of any feeding device 100, it can be understood that after the positioning platform 32 exits the sensing position of one feeding device 100, it moves to the sensing position of the other feeding device 100. The film-tearing device 31 can perform a film-tearing operation on the material 400 in the tray on the positioning platform 32. By cooperating the two feeding devices 100 with a single positioning platform 32 and a single film-tearing device 31, the film-tearing efficiency can be further improved. In other embodiments, the number of feeding devices 100 cooperating with a single film-tearing device 31 can be three or more.

[0071] Reference Figure 6 and Figure 8In some embodiments, the film-tearing device 300 further includes a positioning device 34, which includes two clamping assemblies 341. The two clamping assemblies 341 are disposed opposite each other on both sides of the positioning platform 32 along a second direction Y, and are configured to abut against opposite sides of the material tray. Exemplarily, the clamping assembly 341 includes a clamping cylinder 3411 and a clamping plate 3412. The cylinder body of the clamping cylinder 3411 is connected to the frame 11, and the clamping plate 3412 is connected to the piston rod of the clamping cylinder 3411. When the material tray falls onto the positioning platform 32, the clamping cylinder 3411 drives the clamping plate 3412 towards the center of the sensing station along the second direction Y. The clamping plate 3412 can press against the material tray to fix it, keeping the position of the material tray fixed during the film-tearing operation, thereby improving the film-tearing accuracy.

[0072] Reference Figure 6 In some embodiments, the film-tearing device 31 includes a fixed base 311, a pressing assembly 312, and a film-tearing assembly 313. The pressing assembly 312 is configured to press the material 400 in the material tray. Exemplarily, the pressing assembly 312 includes a pressing robot 3121 and a pressing rod 3122. The fixed base 311 is connected to the frame 11, the pressing robot 3121 is connected to the fixed base 311, and the pressing rod 3122 is connected to the pressing robot 3121. The pressing robot 3121 can drive the pressing rod 3122 to actuate, causing the pressing rod 3122 to peel the edge of the film 41 from the material 400 and press the material 400. In other embodiments, the fixed base 311 may be omitted, and the pressing robot 3121 is connected to the frame 11.

[0073] Reference Figure 6 and Figure 9 In some embodiments, the film-tearing assembly 313 includes a film-tearing drive 3131, a vacuum suction head 3132, grippers 3133, and a clamping drive 3134. Exemplarily, the film-tearing drive 3131 is a robotic arm, and the film-tearing drive 3131 is connected to a fixed base 311. The vacuum suction head 3132 is disposed on the film-tearing drive 3131 and configured to adsorb the film 41 on the material 400 in the material tray. The clamping drive 3134 is disposed on the film-tearing drive 3131 and connected to the grippers 3133. The clamping drive 3134 is configured to drive the grippers 3133 to move toward the vacuum suction head 3132 to press the film 41 against the vacuum suction head 3132.

[0074] It is understandable that the film-tearing drive 3131 drives the vacuum suction head 3132 to act, so that the vacuum suction head 3132 adsorbs the part of the material 400 that is peeled off by the pressing rod 3122 of the film 41. The gripper 3133 is rotatably connected to the vacuum suction head 3132. The gripping drive 3134 is a cylinder, and the cylinder body of the gripping drive 3134 is fixedly connected to the vacuum suction head 3132. The piston rod of the gripping drive 3134 is provided with a connecting pin 3134a, and the gripper 3133 is provided with a connecting hole 3133a. The connecting hole 3133a is elongated, and the connecting pin 3134a is inserted into the connecting hole 3133a. When the piston rod of the gripping drive 3134 drives the connecting pin 3134a to move, the connecting pin 3134a abuts against the inner wall of the connecting hole 3133a, causing the end of the gripper 3133 away from the gripping drive 3134 to rotate toward the vacuum suction head 3132, and pressing the film 41 against the vacuum suction head 3132. Then, the film-tearing drive 3131 drives the vacuum suction head 3132 to move away from the material 400, so that the film 41 can be completely separated from the material 400. In other embodiments, the cylinder of the clamping drive 3134 may also be connected to the film-tearing drive 3131.

[0075] In some embodiments, the film-tearing device 31 further includes a vision detection element 35, which is a miniature camera. The vision detection element 35 is connected to the film-tearing drive element 3131 and electrically connected to the control system of the pressing robot 3121 and the film-tearing drive element 3131. The vision detection element 35 can first take a picture of the material 400 in the tray to record the position of the film 41 to be torn off, thereby improving the accuracy of the pressing rod 3122 and the vacuum suction head 3132 in operating the film 41. In other embodiments, the vision detection element 35 may be omitted, and the position of the material 400 can be accurately positioned by the positioning function of the tray.

[0076] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
