Description

Technical Field

[0001] The present application relates to the technical field of parts conveying, and in particular to a parts conveying platform. Background Art

[0002] When producing certain automotive parts, it is often necessary to use a conveyor table to transport parts between different processes. However, some parts are heavy and large in size, and it is inconvenient for manual labor to carry them onto or remove them from the conveyor table. In this case, a robotic arm is needed to clamp the parts onto the conveyor table. After the parts are transferred to the end of the conveyor table, the robotic arm will clamp the parts to the next process to ensure the smooth progress of the parts production process.

[0003] In order to ensure the stability of the robot arm during the process of transferring parts, the robot arm needs to accurately align with the specific grasping points on the parts when grasping the parts. However, during the movement of the parts on the conveyor table, the parts may be offset on the conveyor table due to external forces. The offset of the part position will cause the robot arm to be unable to align with the grasping points for accurate grasping. At this time, the robot arm may need multiple attempts to successfully grasp the parts. This process will increase the overall production time of the parts and reduce the production efficiency of the parts, which is obviously insufficient. Utility Model Content

[0004] In order to improve the production efficiency of parts, the present application provides a parts conveying table.

[0005] The parts conveying platform provided in this application adopts the following technical solution:

[0006] A parts conveying platform comprises a frame, sprocket assemblies are arranged on opposite sides of the frame, the sprocket assembly comprises two sprockets, the two sprockets are rotatably connected to the two ends of the frame respectively, chains are arranged on the outside of the two sprockets for mutual meshing, a driving assembly for driving the sprockets to rotate is arranged on the frame, a placing plate is arranged on the chain, a positioning assembly is arranged on the placing plate, the positioning assembly comprises a positioning plate arranged on the placing plate, a plurality of outer positioning pins and inner positioning pins are arranged on the positioning plate, the outer positioning pins are in close contact with the outer surface of the parts, and the inner positioning pins are passed through positioning holes opened on the parts.

[0007] By adopting the above technical solution, during transportation, the robot arm is first used to place the parts between multiple outer positioning pins on the positioning plate, and the inner positioning pin is passed through the positioning hole on the part. Then the driving assembly is started. The driving assembly drives the placement plate to move on the frame through the transmission action of the sprocket and the chain, and the placement plate drives the parts on the positioning plate to be transported. During the transmission process, the parts cannot move due to the dual restrictions of the outer positioning pins and the inner positioning pins, which effectively avoids the influence of external force factors on the position of the parts and reduces the possibility of position deviation of the parts during transportation, thereby effectively improving the probability of the robot arm successfully grasping the parts, saving the time of the robot arm grasping the parts, and improving the production efficiency of the parts.

[0008] Optionally, a connecting component is provided on the placement plate, and the positioning plate is detachably connected to the placement plate via the connecting component.

[0009] By adopting the above technical solution, when parts with different shapes need to be transported, the old positioning plate is removed through the connecting component, and then the positioning plate adapted to the new part is installed on the placement plate. The setting of the connecting component realizes the arbitrary replacement of the positioning component on the placement plate, which is convenient for workers to operate while effectively ensuring the positioning effect of the positioning component on automobile parts.

[0010] Optionally, a plurality of interconnected threaded holes are formed on the placement plate and the positioning plate, and the connecting assembly includes connecting bolts threadedly connected in the threaded holes.

[0011] By adopting the above technical solution, when a new positioning plate needs to be replaced, the worker uses a wrench to remove the connecting bolts one by one, then places the positioning plate adapted to the new part on the placement plate, and finally reinstalls the connecting bolts into the threaded hole to achieve a fixed connection between the positioning plate and the placement plate.

[0012] Optionally, the connecting component includes a fixing plate arranged at both ends of the placement plate, the fixing plate is provided with a plurality of through slots, the positioning plate is provided with slots corresponding to the through slots one by one, the through slots and the slots are slidably connected with plug blocks, the plug blocks are provided with pull rods, the pull rods are slidably connected between the through slots and the slots, a limiting ring is provided at one end of the through slot away from the slot, the limiting ring is sleeved on the outer surface of the pull rod, a spring is sleeved on the pull rod, one end of the spring is connected to the limiting ring, and the other end is connected to the plug block, when the spring is in a natural state, the plug block is inserted into the slot, and a pulling component for pulling the pull rod is provided on the placement plate.

[0013] By adopting the above technical solution, when the positioning plate needs to be replaced, the pulling component pulls the pull rod outward, and the pull rod drives the plug block to disengage from the slot and enter the through slot. At this time, the fixing effect of the plug block on the positioning plate disappears, and the worker can take the positioning plate out of the placement plate. When the positioning plate needs to be installed, the worker places the positioning plate on the placement plate and ensures that the slot is aligned with the through slot. Then, the pulling force of the pulling component on the pull rod is canceled. Under the elastic force of the spring, the spring drives the plug block to be inserted into the slot. At this time, the positioning plate is fixed to the placement plate by the plug block. The pulling component and the plug block are used to realize quick disassembly and replacement of the positioning plate, thereby improving the convenience of workers' operation.

[0014] Optionally, a mounting plate corresponding to the fixed plate is provided on the outer peripheral side of the placement plate, and an electromagnetic block corresponding to the through groove is provided on the mounting plate. A magnetic block is provided at one end of the pull rod close to the mounting plate, and when the electromagnetic block is energized, the electromagnetic block adsorbs the magnetic block.

[0015] By adopting the above technical solution, the electromagnetic block adsorbs the magnetic block by energizing and de-energizing the electromagnetic block. When the positioning plate needs to be removed, the electromagnetic block is energized, the magnetic block is driven by the adsorption force to move the pull rod, and the pull rod drives the plug block to detach from the slot. When the positioning plate needs to be installed, the electromagnetic block is de-energized, the adsorption effect on the magnetic block disappears, and the plug block is reinserted into the slot under the action of the spring. The setting of the electromagnetic block and the magnetic block simplifies the steps for workers to manually pull and fix the pull rod, further improving the convenience of replacing the positioning plate.

[0016] Optionally, a support frame is provided on the frame, and support plates are provided on opposite sides of the support frame. The length direction of the support plates is parallel to the length direction of the frame, and the placement plate is slidably connected to the support plates.

[0017] By adopting the above technical solution, when the parts loaded on the placement plate are too heavy, there is a possibility that the placement plate will collapse. The setting of the support plate provides a stable supporting effect on the placement plate, disperses the gravity load of the large mass parts on the placement plate, and reduces the possibility of the placement plate collapsing when subjected to concentrated pressure, thereby ensuring the smooth transportation of the parts on the rack and further improving the production efficiency of the parts.

[0018] Optionally, each of the support plates is rotatably connected to a plurality of rollers, the plurality of rollers are arranged along the length direction of the support plates, and the bottom surface of the placement plate abuts against the end surfaces of the rollers.

[0019] By adopting the above technical solution, the roller converts the sliding friction between the support plate and the placement plate into rolling friction, thereby reducing the friction on the placement plate during movement on the rack, ensuring smooth movement of the placement plate on the rack.

[0020] Optionally, the chains are each provided with a connecting plate corresponding one-to-one to the placing plates, and the placing plates are connected to two adjacent connecting plates by fixing bolts.

[0021] By adopting the above technical solution, the setting of the connecting plate expands the contact area between the placement plate and the chain, improves the stability of the placement plate on the chain, and at the same time the fixing bolts realize the detachable connection between the placement plate and the chain, making it convenient for workers to replace the placement plate.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. The present application sets a positioning component. During the conveying process, the parts cannot move under the restriction of the positioning component, which effectively avoids the influence of external force factors on the position of the parts and reduces the possibility of position deviation of the parts during the conveying process, thereby effectively improving the probability of the robot arm successfully grasping the parts, saving the time of the robot arm grasping the parts and improving the production efficiency of the parts;

[0024] 2. The present application sets a connecting component, and the setting of the connecting component realizes the arbitrary replacement of the positioning component on the placement plate, which is convenient for workers to operate and effectively ensures the positioning effect of the positioning component on automobile parts.

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1-5 This application is described in further detail.

[0032] The embodiment of the present application discloses a parts conveying platform.

[0033] Example 1

[0034] Reference Figure 1 and Figure 2 A parts conveyor includes a frame 1, and sprocket 21 assemblies 2 are arranged on opposite sides of the frame 1. The sprocket 21 assembly 2 includes two sprockets 21, and the two sprockets 21 are respectively rotatably connected to the two ends of the frame 1. A chain 22 is meshed together outside the two sprockets 21. The chain 22 is arranged along the length direction of the frame 1. Two adjacent sprockets 21 between different sprocket 21 assemblies 2 are driven by a connecting shaft 3. The sprocket 21 is fixedly connected to the connecting shaft 3. A rotating motor 31 is fixedly installed on the outer wall of the frame 1, and the output shaft of the rotating motor 31 is fixedly connected to one of the connecting shafts 3.

[0035] Reference Figures 1 to 3 , a plurality of connecting plates 4 are fixedly mounted on each chain 22. In the present embodiment, the number of connecting plates 4 is 3. A placement plate 5 for placing parts is commonly provided between two adjacent connecting plates 4 on different chains 22. The placement plate 5 is connected to the connecting plate 4 by fixing bolts 41. A support frame 6 is fixedly mounted on the frame 1. Support plates 61 are fixedly mounted on opposite ends of the support frame 6. The length direction of the support plate 61 is parallel to the length direction of the frame 1. A plurality of rollers 62 are rotatably connected to each support plate 61. The plurality of rollers 62 are arranged along the length direction of the support plate 61. The bottom surface of the placement plate 5 abuts against the end surface of the roller 62 and is rollingly connected to the support plate 61.

[0036] Reference Figure 1 and Figure 2 When it is necessary to transport, the parts are placed on the placement plate 5 at the starting section of the frame 1 by using a mechanical arm, and then the rotating motor 31 is started, the rotating motor 31 drives the connecting shaft 3 to rotate, and the rotation of the connecting shaft 3 drives the two sprockets 21 fixedly connected to the two ends of the connecting shaft 3 to rotate synchronously, and the rotation of the sprocket 21 drives the meshing chain 22 to move on the frame 1, and in the process of the chain 22 moving, the placement plate 5 is driven to move along the length direction of the frame 1;

[0037] The setting of the support plate 61 provides a stable supporting effect for the placement plate 5, disperses the gravity load of large mass parts on the placement plate 5, and reduces the possibility of collapse of the placement plate 5 when subjected to concentrated pressure. At the same time, under the rolling action of the roller 62, the friction force of the placement plate 5 during the movement is reduced, and the movement of the placement plate 5 on the frame 1 is smoother. When the chain 22 drives the parts to move to the end of the frame 1, the rotating motor 31 is started, and the robot arm grabs the parts and transfers them to the next process.

[0038] Reference Figure 1 and Figure 2 A positioning assembly 7 is provided on the placement plate 5. The positioning assembly 7 includes a positioning plate 71 arranged on the surface of the placement plate 5. A plurality of outer positioning pins 72 and inner positioning pins 73 are fixedly installed on the positioning plate 71. When the part is placed on the positioning plate 71, the outer positioning pins 72 abut against the outer surface of the part, and the inner positioning pins 73 are inserted into the positioning holes opened on the part. During the transmission process, the part cannot move under the dual restrictions of the outer positioning pins 72 and the inner positioning pins 73, which effectively avoids the influence of external force factors on the position of the part and reduces the possibility of position deviation of the part during the transportation process, thereby effectively improving the probability of the robot arm successfully grasping the part, saving the time for the robot arm to grasp the part, and improving the production efficiency of the part.

[0039] Reference Figure 1 and Figure 2 A connecting component 8 is provided on the placing plate 5, and the positioning plate 71 is detachably connected to the placing plate 5 through the connecting component 8. A plurality of threaded holes 51 that are interconnected are provided on the placing plate 5 and the positioning plate 71. In the present embodiment, the number of the threaded holes 51 is four, and the connecting component 8 includes a connecting bolt 81 that is threadedly connected in the threaded hole 51.

[0040] Reference Figure 1 and Figure 2 When it is necessary to transport parts of different shapes, the worker uses a wrench to remove the connecting bolt 81 at the connection between the positioning plate 71 and the placement plate 5, and then places the positioning plate 71 adapted to the new part on the placement plate 5, and finally reinstalls the connecting bolt 81 into the threaded hole 51 to achieve a fixed connection between the positioning plate 71 and the placement plate 5. The setting of the connecting component 8 realizes the arbitrary replacement of the positioning component 7 on the placement plate 5, which is convenient for workers to operate and effectively ensures the positioning effect of the positioning component 7 on the automobile parts.

[0041] The implementation principle of an anti-floating device for a radiator in an embodiment of the present application is as follows: when transportation is required, the robot arm is first used to place the part between the multiple outer positioning pins 72 on the positioning plate 71, and the inner positioning pin 73 is passed through the positioning hole on the part, and then the driving component is started. The driving component drives the chain 22 to move, and the movement of the chain 22 drives the placement plate 5 to move on the frame 1, and the placement plate 5 drives the parts on the positioning plate 71 to be transported. During the transportation process, the parts cannot move under the dual restrictions of the outer positioning pins 72 and the inner positioning pins 73, which effectively avoids the influence of external force factors on the position of the parts and reduces the possibility of position deviation of the parts during transportation, thereby effectively improving the probability of the robot arm successfully grabbing the parts, saving the time of the robot arm grabbing the parts, and improving the production efficiency of the parts.

[0042] Example 2

[0043] Reference Figure 4 and Figure 5 , the difference between embodiment 2 and embodiment 1 is that the connecting component 8 includes a fixing plate 82 fixedly mounted at opposite ends of the placement plate 5, and a plurality of through slots 9 are provided on the fixing plate 82. In the present embodiment, the number of through slots 9 is three, and a slot 10 corresponding to the through slots 9 is provided on the outer peripheral side wall of the positioning plate 71, and the slot 10 and the through slot 9 are of the same size and shape, and an insert block 83 is slidably connected in the slot 10 and the through slot 9, and a pull rod 84 is fixedly connected to the end of the insert block 83 away from the slot 10, and a limiting ring 11 is fixedly connected to the inner peripheral side wall of the through slot 9 away from the slot 10, and one end of the pull rod 84 passes through the limiting ring 11 and is slidably connected to the inside of the through slot 9 and the slot 10, and a spring 85 is sleeved on the outer surface of the pull rod 84, one end of the spring 85 is fixedly connected to the surface of the limiting ring 11, and the other end is fixedly connected to the surface of the insert block 83, when the spring 85 is in a natural state, the insert block 83 is inserted into the inside of the slot 10, and a pulling component 12 for pulling the pull rod 84 outward is provided on the placement plate 5.

[0044] Reference Figure 4 and Figure 5 The pulling assembly 12 includes two mounting plates 121 fixedly mounted on the placing plate 5. The two mounting plates 121 are respectively arranged on the side of the fixing plate 82 away from the positioning plate 71. Electromagnetic blocks 122 corresponding to the through slots 9 are fixedly mounted on the mounting plates 121. A magnetic block 123 is fixedly connected to one end of the pull rod 84 close to the mounting plate 121. When the electromagnetic block 122 is energized, the electromagnetic block 122 adsorbs the magnetic block 123 on the mounting plate 121.

[0045] The implementation principle of Example 2 is as follows: when it is necessary to replace the positioning plate 71 that is adapted to the new part, the worker energizes the electromagnetic block 122, and the magnetic block 123 is attracted by the electromagnetic block 122, driving the pull rod 84 to move in the direction away from the slot 10. After the plug block 83 moves into the through slot 9, the fixing effect of the positioning plate 71 disappears. The worker takes out the old positioning plate 71 from the placement plate 5 and places the new positioning plate 71 on the placement plate 5. Then the worker cancels the power supply to the electromagnetic block 122, the adsorption effect on the magnetic block 123 disappears, and the spring 85 recovers its deformation under the action of elastic force and drives the plug block 83 to be inserted into the slot 10 of the positioning plate 71. At this time, the positioning plate 71 is fixed to the placement plate 5 by the plug block 83. Compared with the worker using a wrench to disassemble and install each connecting bolt 81, the disassembly structure of the pulling assembly 12 and the plug block 83 only requires the worker to remove the positioning plate 71 from the placement plate 5 after energizing the electromagnetic block 122 to achieve replacement. The disassembly process is simple and convenient, which simplifies the disassembly and installation process of the workers.

[0046] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
