Description

Technical Field

[0001] This disclosure relates to the field of glass packaging technology, and in particular to a positioning block fixing spacer paper conveyor device. Background Technology

[0002] In the OLED glass packaging process, spacers are used to separate the glass to prevent damage to the finished product and static electricity adhesion. The spacers need to be transported to the middle of the cardboard box. The number of spacers per pack is limited, and the spacers need to be manually lifted and transported into the paper loading device multiple times. Then, four or more people put the paper loading device into the cardboard box.

[0003] Currently, the spacer paper conveying process involves four people simultaneously lifting a package of spacer paper from a fixed storage location to the ground, then unpacking it and placing it into the paper loading device. The four people then simultaneously lift the fully loaded paper loading device and place it in a fixed position on the cardboard box. This process is time-consuming and causes unnecessary spacer paper consumption. Prolonged operation can easily lead to safety accidents. Furthermore, during the process of lifting the spacer paper rack to the cardboard box, the paper is difficult to convey due to tilting and other factors, and the paper is easily tangled, requiring secondary sorting. To solve this problem, a positioning block is designed to fix the spacer paper conveying device, reducing unnecessary spacer paper loss, improving production efficiency, and ensuring normal production operations. Summary of the Invention

[0004] One technical problem this disclosure aims to solve is to provide a positioning block fixing spacer paper conveyor device. This device reduces the manual operation of lifting and transporting spacer paper to the ground, thereby reducing unnecessary loss of spacer paper due to human error. During the spacer paper conveying process, the spacer paper remains flat at all times, eliminating the need for secondary handling and reducing unnecessary loss of spacer paper, thus improving production efficiency.

[0005] To solve the above-mentioned technical problems, this disclosure provides a positioning block fixing spacer paper conveying rack device, which includes a lifting component and a placement platform. The placement platform is disposed on the lifting component and is driven to rise and fall by the lifting component. A positioning block is provided on the end face of the placement platform away from the lifting component. The positioning block surrounds and forms a placement area for placing spacer paper.

[0006] In some embodiments, the lifting assembly includes a base and a scissor fork, the scissor fork being disposed on the base, and a placement platform being disposed on the scissor fork and driven to lift by the scissor fork;

[0007] The scissor lift includes a lead screw, a first slider, and a second slider. The lead screw has a first thread and a second thread, which have opposite directions of rotation. The first slider is fitted onto the first thread, and the second slider is fitted onto the second thread. When the lead screw rotates, the first slider and the second slider move closer to each other or further away from each other.

[0008] A first scissor bar is provided between the first slider and the second slider and the placement platform, and a second scissor bar is provided between the first slider and the second slider and the base. One end of the first scissor bar is rotatably connected to the placement platform, and the other end of the first scissor bar is rotatably connected to the first slider and the second slider. One end of the second scissor bar is rotatably connected to the base, and the other end of the second scissor bar is rotatably connected to the first slider and the second slider.

[0009] In some embodiments, the placement platform is hollow to form an installation cavity, and a pushing component is provided in the installation cavity for adding spacer paper into the paper box. The pushing component includes a pushing part and an extension part. A pushing hole is opened on the placement platform, the extension part is placed in the installation cavity, and the pushing part is fixed on the extension part and extends out from the pushing hole.

[0010] When the placement platform is pressed against the outer wall of the cardboard box, the extension moves along the push hole and pushes the spacer paper placed in the placement area into the cardboard box.

[0011] In some embodiments, the extension includes an extension plate disposed within a cavity, and a pusher is fixed to the end face of the extension plate facing the pusher hole and extends out of the pusher hole.

[0012] A clearance hole is made on the side wall of the cavity to allow the extension plate to extend out. After the extension plate extends out, it is placed inside the cardboard box.

[0013] In some embodiments, the placement platform and the extension plate are provided with a plurality of balls, and the spacer paper slides on the balls when the pushing part pushes the spacer paper.

[0014] In some embodiments, the pushing part includes a pushing claw, a first sprocket, and a second sprocket, wherein the pushing claw is fixed to the end face of the extension plate and extends out of the pushing hole;

[0015] The first sprocket and the second sprocket are rotatably connected to the side wall of the cavity, and a chain is sleeved between the first sprocket and the second sprocket. The pusher is placed on the side wall of the cavity and fixedly connected to the chain. The movement of the chain drives the pusher to move back and forth along the length of the push hole.

[0016] In some embodiments, an insertion hole is provided on the cardboard box for inserting an extension plate, and a baffle door is rotatably connected to the inner wall of the cardboard box to close or open the insertion hole.

[0017] The outer wall of the cardboard box is equipped with a trigger component, which is linked to the baffle door. When the placement platform is pressed against the outer wall of the cardboard box, it pushes the trigger component to drive the baffle door to rotate.

[0018] In some embodiments, the triggering component includes a fixing hook, a torsion spring, and a push post. The fixing hook is rotatably connected to the inner wall of the cardboard box. The baffle door is provided with a hook hole for the fixing hook to pass through. When the fixing hook passes through the hook hole, the baffle door closes the insertion hole. A through hole is opened on the side wall of the cardboard box. The push post is inserted into the through hole and pushes the fixing hook out of the hook hole.

[0019] The torsion spring is located at the connection between the baffle door and the cardboard box. When the baffle door closes the insertion hole, the torsion spring is subjected to force and deforms.

[0020] In some embodiments, the baffle door is provided with a pressing assembly, which includes a pressing roller and a roller frame. The roller frame is rotatably connected to the edge of the baffle door. The pressing roller is disposed on the roller frame and abuts against the spacer paper when the extension plate is inserted into the paper box.

[0021] In some embodiments, a mounting base is fixed on the placement platform, and one end of the first scissor bar is rotatably connected to the mounting base.

[0022] Through the above technical solution, the spacer paper conveying device provided in this disclosure, with its positioning blocks, limits the spacer paper when it is stacked on the placement platform, ensuring that the spacer paper is stacked neatly. This guarantees the neatness of the spacer paper and prevents the cardboard boxes from sliding, thus preventing manual paper loading. The placement platform is height-adjustable; during spacer paper handling, the platform and its lifting assembly can be raised to the same height as the stacked spacer paper. This reduces the need for manual lifting of the spacer paper to the ground, thereby minimizing unnecessary damage to the spacer paper caused by human error. The positioning blocks ensure that the spacer paper is neatly placed in the appropriate position, facilitating efficient paper retrieval by the paper-picking robot. Using this spacer paper conveying device can significantly improve production efficiency and ensure normal production operations. Attached Figure Description

[0039] Example

[0040] See Figure 1 This invention provides a positioning block fixing spacer paper conveying device, including a lifting assembly 1 and a placement platform 2. The placement platform 2 is used to place spacer papers. Positioning blocks 21 are provided on the placement platform 2. In some embodiments, there are four sets of positioning blocks 21 on the placement platform 2, which can enclose a rectangular area for placing spacer papers; that is, the four sets of positioning blocks 21 can form a placement area. The spacer papers are manually stacked in the placement area, and the spacer papers are positioned by the positioning blocks 21, thus ensuring the neatness of the spacer papers and preventing the paper tray 4 from sliding before manual paper loading. The placement platform 2 can be raised and lowered; during the spacer paper handling process, the placement platform 2 and the lifting assembly 1 can be raised to the same height as the stack of spacer papers. This reduces the manual operation of lifting the spacer papers to the ground, thereby reducing unnecessary damage to the spacer papers caused by human error. The positioning blocks 21 ensure that the spacer papers are neatly placed in the appropriate position, facilitating effective paper picking by the paper-picking robot. Using this spacer paper conveying device can greatly improve production efficiency and ensure normal production operations.

[0041] In some embodiments, the lifting assembly 1 can adopt a conventional scissor lift mode. Specifically, the lifting assembly 1 includes a scissor lift section 12 and a base 11. The base 11 is used to fix the scissor lift section 12 and connect the placement platform 2 to the scissor lift section 12. The lifting of the placement platform 2 is driven by the lifting of the scissor lift section 12. The scissor lift section 12 includes a lead screw 121, a first slider 122, and a second slider 123. Both the first slider 122 and the second slider 123 are sleeved on the lead screw 121. The lead screw 121 has two sets of threads with opposite directions of rotation. The first slider 122 and the second slider 123 are respectively sleeved on one set of threads, that is, the first slider 122 is sleeved on one set of threads, and the second slider 123 is sleeved on the other set of threads with opposite directions of rotation. When the lead screw 121 rotates, the first slider 122 and the second slider 123 can slide along the length direction of the lead screw 121, and during sliding, the first slider 122 and the second slider 123 move closer to each other or further away from each other. The first slider 122 and the second slider 123 are connected to the placement platform 2 via a first scissor bar 124, that is, the first slider 122 and the second slider 123 are each connected to the placement platform 2 via a first scissor bar 124. One end of the first scissor bar 124 is rotatably connected to the first slider 122 and the second slider 123, and the other end of the first scissor bar 124 is rotatably connected to the placement platform 2. A mounting base can be fixed on the end face of the placement platform 2 connected to the first scissor bar 124 to connect the first scissor bar 124 and the second scissor bar 125. The other end of the first scissor bar 124 needs to be rotatably connected to the placement platform 2. The base 11 is connected to the first slider 122 and the second slider 123 via a second scissor bar 125. Specifically, the first slider 122 is connected to the base 11 via one second scissor bar 125, and the second slider 123 is connected to the base 11 via another second scissor bar 125. One end of the second scissor bar 125 is rotatably connected to the first slider 122 and the second slider 123, while the other end is rotatably connected to the base 11. The first connecting rod, the first slider 122, the second connecting rod, and the second slider 123 together form a closed quadrilateral. When the first slider 122 and the second slider 123 approach each other, the first scissor bar 124 pushes the placement platform 2 to rise. When the first slider 122 and the second slider 123 move away from each other, the first scissor bar 124 lowers the placement platform 2, allowing adjustment of the height of the placement platform 2. During the transport of the spacer paper, the placement platform 2 and the lifting assembly 1 can be raised to the same height as the stacking of the spacer paper. This reduces the need for manual labor to lift and transport the spacer paper to the ground, thereby reducing unnecessary damage to the spacer paper caused by human error.

[0042] Given that the process of loading spacer paper still requires manual handling from the placement platform 2 to the paper tray 4, resulting in a relatively large workload and low efficiency, some embodiments can add a pushing component 3 to the placement platform 2 to directly push the spacer paper into the paper tray 4, achieving automatic paper loading. These embodiments require improvements not only to the placement platform 2 but also to the paper tray 4. Specifically, refer to... Figures 2-6 A slot can be provided on the side wall of the cardboard box 4 facing the placement platform 2 for the pusher assembly 3 to extend into, so as to feed the spacer paper placed on the placement platform 2 into the cardboard box 4. A cavity is formed inside the placement platform 2 to form a mounting cavity 22 for mounting the pusher assembly 3. The pusher assembly 3 includes a pusher part 32 and an extension part 31, wherein the pusher part 32 is fixed to the extension part 31 and the extension part 31 can slide within the cavity. A clearance hole needs to be provided on the side wall of the placement platform 2 facing the cardboard box 4. The clearance hole communicates with the mounting cavity 22. When the extension part 31 moves, the extension part 31 can extend from the clearance hole and pass through the slot into the cardboard box 4. The placement platform 2 has a push hole on its end face for placing spacer paper. The push hole extends towards the clearance hole. The push part 32 is placed in the cavity and extends out from the push hole to limit the spacer paper placed on the placement platform 2. When spacer paper needs to be pushed into the paper tray 4, the push part 32 can also move along the push hole. At the same time as the push part 32 moves, the extension part 31 also moves and extends out from the clearance hole and is inserted into the paper tray 4 through the insertion hole to feed the spacer paper into the paper tray 4. After the spacer paper is fed into the paper tray 4, the extension part 31 retracts, thus completing the push of the spacer paper. In the whole process, only manual handling of the spacer paper on the placement platform 2 is required to achieve automatic paper feeding into the paper tray 4, reducing manual intervention, reducing labor intensity, and improving paper feeding efficiency.

[0043] In some embodiments, the pushing part 32 includes a pushing claw 321, a first sprocket 322, and a second sprocket 323. The pushing claw 321 is fixed to the extension part 31 and extends out of the pushing hole. The first sprocket 322 and the second sprocket 323 are rotatably connected to the side wall of the cavity, and a chain 324 is sleeved between the first sprocket 322 and the second sprocket 323. The side wall of the pushing claw 321, which is located in the cavity, is fixedly connected to the chain 324. The movement of the chain 324 causes the pushing claw 321 to move back and forth along the length of the pushing hole. Since the pushing claw 321 is also fixed to the extension part 31, the extension part 31 slides synchronously in the mounting cavity 22 while the pushing claw 321 moves. The extension part 31 includes an extension plate 311, which is placed in the cavity. The pushing claw 321 is fixed to the end face of the extension plate 311 facing the pushing hole and extends out of the pushing hole and is placed in the cardboard box 4.

[0044] In the initial state, the pusher claw 321 is positioned at the end of the push hole away from the clearance hole, and the extension plate 311 is fully retracted into the mounting cavity 22. Spacer sheets are stacked and placed on the placement platform 2, with one side of the stack abutting the pusher claw 321 to achieve neat stacking. When paper needs to be fed into the cardboard box 4, the placement platform 2 is first manually pushed to one side of the cardboard box 4 and abutted against the side wall, aligning the clearance hole with the insertion hole. At this time, the first sprocket 322 and the second sprocket 323 rotate, driving the pusher claw 321 to move. Simultaneously, the extension plate 311 extends from the mounting cavity 22, passing through the clearance hole and the insertion hole, and finally into the cardboard box 4. As the pusher claw 321 pushes, the stack of spacer sheets also moves forward onto the extension plate 311, which is now placed inside the cardboard box 4, thus pushing the stack of spacer sheets into the cardboard box 4 as well. Subsequently, the extension plate 311 returns, and the spacer stack remains in the paper box 4 due to the step surface formed by the height difference between the extension plate 311 and the placement platform 2. Throughout the process, the spacer stack remains basically intact, reducing the amount of manual sorting work and thus reducing the labor intensity of manual labor, while also improving the efficiency of paper feeding.

[0045] In some embodiments, to reduce resistance when the extension plate 311 retracts, multiple sets of holes are formed on the surface of the extension plate 311, and a ball bearing 312 is engaged in each hole. The ball bearing 312 can rotate freely within the hole, and its outer surface is higher than the end face of the extension plate 311. That is, when the neatly stacked spacer paper is pushed onto the extension plate 311 by the pusher claw 321, the bottommost layer of spacer paper actually contacts the ball bearing 312. When the paper feeding ends and the extension plate 311 retracts to its original position, the ball bearing 312 contacts the spacer paper and rolls, reducing the possibility of the spacer paper being brought back when the extension plate 311 resets.

[0046] In some embodiments, a baffle door 41 can be provided at the insertion hole on the paper box 4 to close or open the insertion hole. If no paper needs to be added to the paper box 4, the baffle door 41 will close the insertion hole, reducing the possibility of the spacer paper inside the paper box 4 coming into contact with the outside, thereby reducing the possibility of the spacer paper being contaminated. Specifically, the baffle door 41 can be hinged to the paper box 4, and when the insertion hole needs to be opened, the baffle door 41 will flip inward to ensure that the spacer paper can smoothly enter the paper box 4. Since the baffle door 41 needs to be in a normally closed state when no paper needs to be added, a trigger component 5 needs to be installed on the side wall of the paper box 4 to trigger the baffle door 41 to flip. When the placement platform 2 abuts against the side wall of the paper box 4, it can push the trigger component 5 to release the baffle door 41.

[0047] In some embodiments, the trigger assembly 5 includes a fixing hook 51, a torsion spring, and a push post 52. The torsion spring is sleeved at the junction of the baffle door 41, with one end of the torsion spring fixed to the baffle door 41 and the other end fixed to the hinge shaft at the hinge or directly fixed to the side wall of the cardboard box 4. When the baffle door 41 closes the insertion hole, the torsion spring of the baffle door 41 is in a compressed and deformed state. The fixing hook 51 is rotatably connected to the cardboard box 4 on one side of the insertion hole, and a hook hole needs to be opened on the baffle door 41 accordingly. In the initial state, the fixing hook 51 is inserted into the hook hole to hook the baffle door 41 to close the insertion hole. Of course, a through hole also needs to be opened on the side wall of the cardboard box 4 for the push post 52 to be inserted into the cardboard box 4. The end of the push post 52 inserted into the cardboard box 4 needs to be rotatably connected to the fixing hook 51. By pushing the push post 52, the push post 52 can be driven to move inward. At this time, the push post 52 can drive the fixing hook 51 to rotate and disengage from the hook hole. Then the torsion spring returns to its original position, causing the baffle door 41 to flip. When the placement platform 2 moves to the paper tray 4, the pushing force of the placement platform 2 drives the pushing column 52 to move into the paper tray 4, thereby disengaging the fixing hook 51 from the hook hole. This ensures that the paper feed hole is open before feeding and will not affect paper feeding. After feeding, the baffle door 41 can be manually closed again, reducing the possibility of the spacer paper being contaminated.

[0048] In some embodiments, a pressing assembly 6 may be provided at the bottom of the baffle door 41. Specifically, the pressing assembly 6 includes a pressing roller 61 and a roller frame 62. A rotating shaft needs to be inserted through the bottom of the baffle door 41. The rotating shaft can be fixed to the baffle door 41, and both ends of the rotating shaft need to extend out of the baffle door 41. The roller frame 62 is sleeved on the ends of the rotating shaft so that it can rotate around the rotating shaft. At least one pressing roller 61 is rotatably connected to the roller frame 62. When the baffle door 41 is flipped up, the pressing assembly 6 swings downward due to its own weight, pressing on the spacer paper fed into the paper tray 4 to limit the spacer paper. As long as the baffle door 41 is in the flipped open state, the pressing roller 61 will always press on the spacer paper to always play the role of pressing and limiting the spacer paper. Thus, when the extension plate 311 is reset, it can press down the stacked spacer paper, further reducing the possibility of the spacer paper moving with the extension plate 311.

[0049] This disclosure provides a positioning block-fixed spacer paper conveying device. In use, spacer papers are manually stacked on a placement platform 2, and each spacer paper is positioned within a designated area and limited by a positioning block 21. This ensures the spacer papers are stacked neatly, preventing the cardboard box 4 from sliding before manual loading. The placement platform 2 is height-adjustable; during spacer paper handling, the platform and lifting component 1 can be raised to the same height as the stacked spacer papers. This reduces the need for manual lifting of the spacer papers to the ground, minimizing unnecessary damage due to human error. The positioning block 21 ensures the spacer papers are neatly positioned, facilitating efficient paper retrieval by the paper-picking robot. Using this spacer paper conveying device significantly improves production efficiency and ensures normal production operations. Furthermore, a pushing component 3 can be added to the placement platform 2. This component pushes the spacer papers stacked on the platform 2 into the cardboard box 4, enabling automatic paper loading and further reducing unnecessary damage to the spacer papers due to human error while also improving production efficiency.
