Description

Technical Field

[0001] This utility model relates to the field of panel production equipment technology, and in particular to a material transfer device. Background Technology

[0002] Reference Figure 1 and Figure 2 As shown, during the display panel production process, a film application process is required. In this process, the film 1' is first placed on a tray 3' and transferred to the corresponding film application stage. Then, the film is applied to the display panel using the appropriate film application equipment. During the film transfer process, the tray 3' containing the films 1' is typically placed on the transfer platform 4' of the transfer equipment. The robotic arm 2' of the transfer equipment is equipped with multiple suction nozzles 21', which pick up the films 1' one by one from the tray 3' and transfer them to the corresponding processing equipment. The number of films 1' on each tray 3' is not exactly the same during loading, and the quantity of films 1' of different specifications will also vary.

[0003] The existing technology has the following shortcomings: Traditional transfer equipment cannot identify the number of films 1' in the tray 3'. It can only perform the corresponding number of adsorption operations based on the number of films 1' provided during loading. If the number of films 1' input during loading is inconsistent with the actual number on the tray 3', it is easy for the robot arm 2' to continue adsorption after adsorbing all the films 1' on the tray 3', thus directly adsorbing the entire tray 3', causing equipment interference, damage to the equipment, and in severe cases, safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a material transfer device that can effectively identify whether the material in the pallet has been transferred, avoid picking up empty pallets, prevent equipment interference and damage, and improve operational safety.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A material transfer device is provided, including a frame, a drive component, and a detection component. The frame is provided with a picking component, a control switch, and a mounting slot. The frame has a first side facing the tray. The picking component is disposed on the first side. The mounting slot is recessed on the first side. The control switch is disposed in the mounting slot. The control switch is connected to the picking component and is used to control the picking component.

[0007] The drive unit is connected to the frame and is used to drive the frame closer to or away from the tray;

[0008] The detection element is retractably disposed within the mounting groove, with a portion of the detection element protruding from the first side. The tray has a second side facing the first side, and a clearance hole is provided on the second side. The material on the tray can cover the clearance hole. The detection element has a first position and a second position. When the detection element is in the first position, it protrudes from the first side and can be inserted into the clearance hole, and the detection element is spaced apart from the control switch. When the detection element abuts against the material, it can move from the first position to the second position, and when the detection element is in the second position, it is connected to the control switch.

[0009] In one embodiment of the material transfer device, the control switch includes an electromagnet, and the end of the detection element facing the control switch is provided with a magnetic element that magnetically engages with the electromagnet.

[0010] In one embodiment of the material transfer device, the detection element includes a rod and an anti-detachment part. The rod is partially inserted into the mounting groove, and the anti-detachment part is located in the mounting groove. A limiting part is provided in the mounting groove, and the anti-detachment part abuts against the limiting part to prevent the rod from detaching from the mounting groove.

[0011] In one embodiment of the material transfer device, multiple mounting slots are provided, and the detection element can be detachably inserted into any one of the mounting slots.

[0012] In one embodiment of the material transfer device, the detection element further includes a first elastic element. The anti-detachment part is connected to the rod body through the first elastic element. The first elastic element always has a tendency to drive the anti-detachment part and the rod body away from each other. The first elastic element can cause the anti-detachment part to abut against the limiting part to prevent the rod body from detaching from the mounting groove. The anti-detachment part moves toward the rod body to compress the first elastic element so that the rod body can detach from the mounting groove.

[0013] In one embodiment of the material transfer device, the frame is further provided with a disassembly groove and a disassembly assembly. The disassembly groove includes a first slide groove and a second slide groove that are interconnected. The first slide groove is connected to the mounting groove. The disassembly assembly includes a top rod and an operating rod that are interconnected. The top rod is movably disposed in the first slide groove and selectively abuts against the anti-detachment part. The operating rod is movably disposed in the second slide groove, and part of the operating rod extends out of the second slide groove and extends to the outside of the frame.

[0014] In one embodiment of the material transfer device, a second elastic element is provided in the second chute, the second elastic element is connected to the operating rod, and the second elastic element always has the tendency to drive the operating rod away from the mounting groove.

[0015] In one embodiment of the material transfer device, the picking component includes multiple suction nozzles, which are connected to a pneumatic assembly. The pneumatic assembly and the control switch are respectively connected to a control system.

[0016] In one embodiment of the material transfer device, a third elastic element is provided on a groove wall in which the control switch is located. The end of the third elastic element away from the groove wall is connected to the detection element, and the third elastic element always has the tendency to drive the detection element away from the groove wall.

[0017] In one embodiment of the material transfer device, the end face of the detection element facing the clearance hole is configured as an arc surface.

[0018] The beneficial effects of this invention are as follows: This device, through the cooperation of a detection element and a clearance hole, is used to detect whether all the material on a tray has been removed. Specifically, when there is material on the tray, as the robotic arm moves towards the tray under the drive of the drive element, the detection element touches the material and is blocked by the material, retracting into the mounting slot and triggering the control switch. The control switch then controls the picking component to pick up the material. Conversely, when all the material on the tray has been removed, the detection element loses the obstruction of the material. Thus, when the robotic arm moves towards the tray, the detection element directly inserts into the clearance hole of the tray, preventing it from moving into the mounting slot to trigger the control switch. In this case, the picking component does not perform a picking action, avoiding serious problems such as mechanical collisions, equipment interference, and component damage caused by directly removing the tray.

[0033] The advantages and features of this invention, as well as methods of implementing them, will become apparent from the following detailed description of the embodiments in conjunction with the accompanying drawings. However, this invention is not limited to the embodiments disclosed below, but can be implemented in various different forms. These embodiments are provided merely to complete the disclosure of this invention and to enable those skilled in the art to fully understand its scope, which is defined only by the scope of the claims. The same reference numerals denote the same constituent elements throughout the specification.

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 3 and Figure 4As shown, the material transfer device of this utility model embodiment includes a frame 1, on which a picking component, a control switch 12 and a mounting groove 13 are provided. The frame 1 has a first side 14 facing the tray 2. The picking component is disposed on the first side 14. The mounting groove 13 is recessed on the first side 14. The control switch 12 is disposed in the mounting groove 13. The control switch 12 is connected to the picking component and is used to control the picking component. In practical applications, the control switch 12 and the picking component can be electrically connected or signal connected, as long as the picking component can be controlled by the control switch 12.

[0036] A drive unit (not shown) is connected to the frame 1 and is used to drive the frame 1 to move closer to or away from the tray 2.

[0037] The detection element 3 is retractably disposed within the mounting groove 13. Part of the detection element 3 protrudes from the first side 14. The tray 2 has a second side 21 facing the first side 14. A clearance hole 22 is provided on the second side 21. The material 4 on the tray 2 can cover the clearance hole 22. The detection element 3 has a first position and a second position. When the detection element 3 is in the first position, the detection element 3 protrudes from the first side 14 and can be inserted into the clearance hole 22. The detection element 3 is spaced apart from the control switch 12. When the detection element 3 abuts against the material 4, the detection element 3 can move from the first position to the second position. When the detection element 3 is in the second position, the detection element 3 is connected to the control switch 12.

[0038] In this embodiment, a tray 2 loaded with material 4 is placed on a transfer platform 5, and then the frame 1 above the transfer platform 5 transfers the material 4 on the tray 2. During the operation, the detection element 3, in cooperation with the clearance hole 22, is used to detect whether the material 4 on the tray 2 has been completely removed. Specifically, when material 4 is placed on the tray 2, the material 4 will block the clearance hole 22. When the frame 1 moves towards the tray 2 under the drive of the drive element, the detection element 3 touches the material 4 and is blocked by the material 4, retracting into the mounting groove 13 and connecting to the control switch 12. The control switch 12 controls the picking component to pick up the material 4. Conversely, when all the material 4 on the tray 2 has been removed, the clearance hole 22 will no longer be blocked by the material 4. As a result, when the frame 1 moves toward the tray 2, the detection element 3 can be directly inserted into the clearance hole 22 of the tray 2, and thus cannot move into the mounting slot 13 to connect the control switch 12. At this time, the picking component will not perform the picking action to avoid directly taking away the tray 2, thereby causing serious problems such as mechanical collision, equipment interference and component damage.

[0039] In actual operation, the frame 1 adopts the existing multi-axis robot structure, and the drive component is a conventional robot drive structure. As long as the drive component can drive the frame 1 to deliver the material 4 on the tray 2 to the corresponding other workstations, the specific robot structure and drive component structure are existing technologies and will not be described in detail here.

[0040] In one embodiment of the material transfer device, the control switch 12 includes an electromagnet 121. The end of the detection element 3 facing the control switch 12 is provided with a magnetic element 34 that magnetically engages with the electromagnet 121. When the detection element 3 is in the second position and connected to the control switch 12, the electromagnet 121 is energized and magnetically engages with the magnetic element 34, fixing the detection element 3 within the mounting groove 13. This ensures that the bottom of the detection element 3 is higher than the bottom of the picking component, preventing damage to the material 4 caused by the detection element 3 constantly pressing on the material 4 during the picking and transfer process. Simultaneously, the electromagnet 121 attracts the magnetic element 34, fixing the detection element 3 within the mounting groove 13 and maintaining continuous contact with the control switch 12, ensuring the picking component maintains normal operation during transfer and preventing the material 4 from falling.

[0041] In one embodiment of the material transfer device, taking a film as material 4 as an example, the picking component includes multiple suction nozzles 11. The suction nozzles 11 are connected to a pneumatic assembly (not shown), and the pneumatic assembly and control switch 12 are respectively connected to the control system (not shown). Specifically, the suction nozzles 11 move towards the tray 2 and abut against the upper end of the film. At this time, the detection element 3 abuts against the top surface of the film and is lifted by the film to the second position. The detection element 3 is connected to the control switch 12, which transmits a signal to the control system of the material transfer device. The control system simultaneously energizes the electromagnet 121 and starts the pneumatic assembly, allowing the suction nozzles 11 to pick up the film. Then, the film is moved to the designated position by the drive component. The control system shuts down the pneumatic assembly to stop the suction nozzles 11 from adsorbing the film, thus separating the film from the suction nozzles 11. At the same time, the control system transmits a control signal to the control switch to de-energize the electromagnet 121 to release the magnetic attraction connection with the magnetic element 34. The detection element 3 falls back to the first position and is spaced apart from the control switch 12, waiting for the next picking operation.

[0042] In this embodiment, the film is a surface-sealed pressure-sensitive adhesive metal film, which has the functions of water resistance and impact protection. In addition, it has a multi-layer structure and a certain degree of hardness, so that when the detection element 3 moves toward the tray 2, the film 4 can smoothly push the detection element 3 upward to the second position so that the detection element 3 can be connected to the control switch 12.

[0043] like Figure 3 and Figure 4As shown, in one embodiment of the material transfer device, a third elastic element 8 is provided on the wall of the mounting groove 13 where the control switch 12 is located. The end of the third elastic element 8 away from the groove wall is connected to the detection element 3. The third elastic element 8 always has a tendency to drive the detection element 3 away from the groove wall. The third elastic element 8 can prevent the detection element 3 from getting stuck in the mounting groove 13 after it is disconnected from the control switch 12, thereby effectively ensuring that the detection element 3 resets in time after being disconnected from the control switch 12. Specifically, after the film transfer is completed, the electromagnet 121 is de-energized and releases its magnetic attraction with the magnetic attractor. At this time, the detection element 3 is disconnected from the control switch 12. Driven by the third elastic element 8, the detection element 3 can be separated from the control switch 12 and reset in time to wait for the next detection operation.

[0044] In one embodiment of the material transfer device, the detection element 3 includes a rod 31 and an anti-detachment part 32. The rod 31 is partially inserted into the mounting groove 13, and the anti-detachment part 32 is located in the mounting groove 13. A limiting part 131 is provided in the mounting groove 13. The anti-detachment part 32 abuts against the limiting part 131 to prevent the rod 31 from detaching from the mounting groove 13.

[0045] In one embodiment of the material transfer device, multiple mounting slots 13 are provided, and the detection element 3 can be detachably inserted into any one of the mounting slots 13. According to the position of the corresponding clearance hole 22 on the pallet 2 of different specifications, multiple mounting slots 13 are provided respectively corresponding to the clearance hole 22 on the pallet 2 of various specifications, so that the detection element 3 can be disassembled and installed into the corresponding mounting slot 13 according to the specifications of the pallet 2 used, so that the detection element 3 can be targeted for detection.

[0046] like Figures 4 to 7As shown, in one embodiment of the material transfer device, the detection element 3 further includes a first elastic element 33. The anti-detachment part 32 is connected to the rod body 31 through the first elastic element 33. The first elastic element 33 always has a tendency to drive the anti-detachment part 32 and the rod body 31 away from each other. The first elastic element 33 drives the anti-detachment part 32 away from the rod body 31 and makes the anti-detachment part 32 abut against the limiting part 131 to prevent the rod body 31 from detaching from the mounting groove 13. The anti-detachment part 32 moves closer to the rod body 31 to compress the first elastic element 33, so that the rod body 31 can detach from the mounting groove 13. Therefore, when disassembling the detection element 3, the anti-detachment part 32 is moved closer to the rod body 31 to compress the first elastic element 33. So when the rod body 31 moves away from the mounting groove 13, the anti-detachment part 32 is not restricted by the limiting part 131 during the movement with the rod body 31, so that the detection element 3 can be completely detached from the mounting groove 13 and the disassembly is completed. Similarly, when installing the test piece 3, first move the anti-detachment part 32 close to the rod body 31, smoothly insert the test piece 3 into the mounting groove 13 and place the anti-detachment part 32 in the mounting groove 13, then release the anti-detachment part 32. Under the action of the first elastic member 33, the anti-detachment part 32 moves away from the rod body 31. At this time, the limiting part 131 limits the anti-detachment part 32 again to prevent the rod body 31 from falling out of the mounting groove 13.

[0047] like Figure 6 and Figure 7 As shown, in one embodiment of the material transfer device, the frame 1 is further provided with a disassembly groove 6 and a disassembly assembly 7. The disassembly groove 6 includes a first slide groove 61 and a second slide groove 62 that are interconnected. The first slide groove 61 is connected to the mounting groove 13. The disassembly assembly 7 includes a push rod 71 and an operating rod 72 that are interconnected. The push rod 71 is movably disposed in the first slide groove 61 and selectively abuts against the anti-detachment part 32. The operating rod 72 is movably disposed in the second slide groove 62, with a portion of the operating rod 72 extending out of the second slide groove 62 and extending to the outside of the frame 1. Specifically, by pushing the operating rod 72 to slide in the second slide groove 62, the operating rod 72 can drive the push rod 71 to move in the first slide groove 61 and enter the mounting groove 13, thereby abutting against the anti-detachment part 32 and pushing the anti-detachment part 32 to move in the direction close to the rod body 31, thereby releasing the restriction of the limiting part 131 on the anti-detachment part 32, making it convenient to remove the detection piece 3 from the mounting groove 13.

[0048] In one embodiment of the material transfer device, a second elastic element 73 is provided in the second chute 62. The second elastic element 73 is connected to the operating rod 72. The second elastic element 73 always tends to drive the operating rod 72 away from the mounting groove 13. Thus, after the detection element 3 is disassembled using the operating rod 72, releasing the operating rod 72 allows it to reset under the action of the second elastic element 73, avoiding interference with the reinstallation of the detection element 3. In actual operation, the operator can easily disassemble the detection element 3 by pressing the operating rod 72, which improves the efficiency of disassembly and assembly of the detection element 3 and reduces the labor intensity of the operator.

[0049] Furthermore, in other embodiments, a pressing part 9 is also included, such as... Figure 8 As shown, one end of the pressing part 9 is connected to the anti-detachment part 32, and the other end of the pressing part 9 extends out of the mounting groove 13. The operator presses the pressing part 9, which in turn moves the anti-detachment part 32 closer to the rod body 31 to squeeze the first elastic member 33, thus releasing the anti-detachment part 32 from the restriction of the limiting part 131, allowing the detection piece 3 to be removed from the mounting groove 13. Alternatively, as... Figure 9 As shown, the pressing part 9 is located between the anti-detachment part 32 and the first elastic member 33. The operator presses the pressing part 9 to move the anti-detachment part 32 closer to the rod body 31 and squeeze the first elastic member 33, thereby freeing the anti-detachment part 32 from the restriction of the limiting part 131, facilitating the removal of the detection piece 3 from the mounting groove 13. Of course, in actual operation, other structures can also be used, as long as they can achieve the goal of moving the anti-detachment part 32 to free it from the restriction of the limiting part 131, thus facilitating the removal of the detection piece 3 from the mounting groove 13. Such designs are all within the protection scope of this utility model.

[0050] like Figure 3 and Figure 4 As shown, in one embodiment of the material transfer device, the end face of the detection element 3 facing the clearance hole 22 is set as an arc surface 35 to prevent damage to the film covering the clearance hole 22 when the detection element 3 moves toward the clearance hole 22. Furthermore, a flexible buffer layer (not shown) can also be provided on the arc surface 35. The flexible buffer layer can be a structure such as a sponge pad or a rubber pad to further reduce the damage to the film by the detection element 3.

[0051] Although embodiments of the present invention have been described above with reference to the accompanying drawings, the present invention is not limited to the above embodiments, but can be made in various forms, and those skilled in the art will understand that the present invention can be implemented in other specific forms without changing the technical spirit or essential characteristics of the present invention. Therefore, it should be understood that the above embodiments are exemplary in all respects and not restrictive.
