Description

Technical Field

[0001] This utility model relates to the field of tablet computer assembly technology, specifically a robotic arm for a loader. Background Technology

[0002] A tablet computer is composed of multiple parts, including a front cover, screen, motherboard, and back cover. During the assembly of a tablet computer, a robotic arm is used to pick up and transfer some of the components to their assembly positions for installation.

[0003] The existing loader robotic arm uses a three-axis hybrid drive architecture to adsorb and transfer components assembled on a tablet computer. During the transfer process, the robotic arm needs to undergo different rotational adjustments to move the items from the transmission structure to the processing station. During the adjustment process, the connecting parts of the robotic arm are constantly rotated. The friction between the rotating structures causes the local temperature of the robotic arm to rise, and the wear generated by the rotation increases, which in turn affects the transfer accuracy and service life of the robotic arm. Optimization and improvement are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a robotic arm for a loader, so as to solve the problem mentioned in the background art that when the robotic arm transfers and adjusts the product, the rotating connection part is prone to wear, which affects the transfer accuracy and service life of the robotic arm.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a loader robotic arm, comprising: a mounting base, a swing arm disposed on one side of the mounting base, and a connector disposed on one side of the swing arm, the bottom end of the connector being connected to a connecting member; and further comprising a heat dissipation adjustment component and an adsorption adjustment component.

[0006] The heat dissipation adjustment component is located inside the connector. It includes heat dissipation fins, an oil reservoir inside the fins, and an arc-shaped pressure plate at the top of the oil reservoir. An actuating block is located at the top of the arc-shaped pressure plate. The heat dissipation adjustment component is used for temperature control of the rotating connection part of the robotic arm. The adsorption adjustment component is located at the bottom of the connector. It includes a rotating rod, a fixing plate at the bottom of the rotating rod, and suction cups at both ends of the bottom of the fixing plate. The adsorption adjustment component is used for adjusting the adsorption position of the workpiece.

[0007] Preferably, the bottom end of the connector is connected to a rotating seat, and the bottom end of the rotating seat is connected to a positioning plate.

[0008] Preferably, the oil storage box is located at the inner top of the connector, and both ends of the oil storage box are provided with liquid outlet pipes.

[0013] Preferably, an air nozzle is installed on the inner side of the fixing plate, and a connector is connected to the bottom inner side of the air nozzle, with the suction cup located at the bottom of the connector.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention increases the heat dissipation area by setting heat dissipation fins at the joints of the robotic arm, and then sets up a toggle block and an arc-shaped pressure plate to collide and squeeze, so that the lubricating oil inside the oil reservoir can be intermittently and evenly applied to the rotating friction positions of the connector and the connector head, intermittently replenishing the lost lubricating oil, reducing friction, avoiding excessively rapid temperature rise, reducing wear, and ensuring the transfer accuracy and service life of the robotic arm.

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0024] like Figure 1 - Figure 4 As shown, this application provides a loader robotic arm, including: a mounting base 1, a swing arm 2 is provided on one side of the mounting base 1, and a connector 3 is provided on one side of the swing arm 2, with a connector 4 connected to the bottom end of the connector 3;

[0025] A heat dissipation adjustment component is provided on the inner side of the connector 3. The heat dissipation adjustment component includes heat dissipation fins 6. An oil storage box 8 is provided on the inner side of the heat dissipation fins 6. An arc-shaped pressure plate 13 is provided on the top of the oil storage box 8. A toggle block 7 is provided on the top of the arc-shaped pressure plate 13. The heat dissipation adjustment component is used for temperature control adjustment of the rotating connection part of the robotic arm.

[0026] Specifically, such as Figure 2 and Figure 3 As shown, the oil reservoir 8 is located on the inner top of the connector 4. Both ends of the oil reservoir 8 are provided with liquid outlet pipes 9. The liquid outlet pipes 9 are arc-shaped and have multiple outlet pipes. The arc-shaped design fits the connector 4 to improve the uniformity of lubricant application.

[0027] Specifically, such as Figure 3 As shown, the inside of the oil reservoir 8 is equipped with a built-in sponge pad 10, which is used to absorb the lubricating oil and prevent it from flowing out quickly.

[0028] Specifically, such as Figure 3 As shown, an elastic connecting rod 12 is connected inside the top wall of the oil storage box 8, and a pressing plate 11 is connected to the bottom end of the elastic connecting rod 12. When the arc-shaped pressing plate 13 is subjected to pressure, it drives the elastic connecting rod 12 and the pressing plate 11 to press the built-in sponge pad 10 downward.

[0029] Specifically, such as Figure 3As shown, the arc-shaped pressure plate 13 is located at the top of the elastic connecting rod 12. A protrusion is provided on the outer side of the arc-shaped pressure plate 13. The actuating block 7 is attached to the arc-shaped pressure plate 13. When the connector 3 and the connector 4 rotate relative to each other for adjustment, the actuating block 7 intermittently squeezes the protrusion, causing the arc-shaped pressure plate 13 to move.

[0030] The bottom end of the connector 4 is provided with an adsorption adjustment component, which includes a rotating rod 15. The bottom end of the rotating rod 15 is provided with a fixing plate 16. Both ends of the bottom of the fixing plate 16 are provided with suction cups 19. The adsorption adjustment component is used to adjust the adsorption position of the workpiece.

[0031] Specifically, such as Figure 1 As shown, the bottom end of the connector 4 is connected to a rotating seat 5, and the bottom end of the rotating seat 5 is connected to a positioning plate 14. The positioning plate 14 has multiple mounting slots inside, and the position of the air nozzle 17 can be adjusted according to actual needs.

[0032] Specifically, such as Figure 1 and Figure 4 As shown, the rotating rod 15 is connected to the bottom end of the positioning plate 14. By rotating the rotating rod 15, the air nozzle 17 at the bottom end of the fixed plate 16 is driven to adjust its orientation.

[0033] Specifically, such as Figure 4 As shown, an air nozzle 17 is installed on the inner side of the fixing plate 16, and a connector 18 is connected to the bottom inner side of the air nozzle 17. A suction cup 19 is located at the bottom of the connector 18. The suction cup 19 is installed on the inner side of the air nozzle 17 through the connector 18 for easy replacement.

[0034] In this embodiment: heat dissipation fins 6 are set at the position of the rotating joint of the robotic arm to increase the heat dissipation area. Then, the collision and squeezing of the toggle block 7 and the arc-shaped pressure plate 13 are set so that the lubricating oil inside the oil storage box 8 can be intermittently and evenly applied to the rotating friction position of the connector 4 and the connector 3, intermittently replenishing the lost lubricating oil, reducing friction, and achieving the effect of cooling. When the robotic arm transfers the product, two air nozzles 17 are installed through the fixing plate 16. The position of the air nozzles 17 can be adjusted under the connection of the rotating rod 15. When the suction cup 19 at one end is covered with dust and affects the adsorption firmness, the position can be adjusted.

[0035] Specifically, this solution involves the following: During the assembly of the tablet computer, a robotic arm is used for position transfer. During this transfer, friction occurs at the rotating connection points. To reduce the temperature at these points, heat dissipation fins 6 are installed to increase the heat dissipation area and improve heat dissipation. When the connector 3 and connector 4 are rotated and adjusted, the toggle block 7 intermittently presses the protrusions on the arc-shaped pressure plate 13, causing the arc-shaped pressure plate 13 to move. When the arc-shaped pressure plate 13 is under pressure, it causes the elastic connecting rod 12 and the extrusion plate 11 to press down on the built-in sponge pad 10, squeezing the lubricating oil from the built-in sponge pad 10 out through the outlet pipe 9. The outlet pipe 9 is arc-shaped and has multiple outlet pipes, fitting snugly against the connector 4. The arc-shaped setting improves the uniformity of lubricant application, reduces friction by increasing lubrication, and extends the service life of the robotic arm. During the transfer process, the positioning plate 14 has multiple mounting slots inside to adjust and install the rotating rod 15. Then, by rotating the rotating rod 15, the air nozzle 17 at the bottom of the fixed plate 16 is adjusted in position. Two air nozzles 17 are installed on both sides of the bottom of the fixed plate 16. The position of the air nozzles 17 can be adjusted under the connection of the rotating rod 15. When the suction cup 19 at one end is covered with dust and affects the adsorption strength, the position can be changed to allow the suction cup 19 at the other end to adsorb. It can also be used simultaneously when transferring large parts to increase the adsorption strength and improve the efficiency of the equipment.
