Description

Technical Field

[0001] The utility model relates to the technical field of feeding devices, and particularly relates to a multi-station feeding manipulator. Background Art

[0002] During the production process of capacitors, the lead wires need to be cleaned. By cleaning, the pollutants on the surface of the lead wires can be removed. If these pollutants are not removed, it may cause poor contact and increased resistance, affecting the normal operation of the capacitors in the circuit. It also helps to improve the welding performance, improve the wettability and bonding strength of the welding, and ensure reliable welding.

[0003] When a capacitor cleaning machine cleans capacitors, a manipulator needs to be used for assistance, which is responsible for taking out the cleaned capacitors and placing the capacitors to be cleaned on the cleaning station. Currently, it is often achieved by driving the clamping jaws through a motor module. However, when using a motor module to realize the clamping and transfer operation of the clamping jaws, two motor modules in two axial directions are often required, which results in more motor actions during work, a relatively slow production beat, and room for efficiency improvement. Therefore, those skilled in the art have provided a multi-station feeding manipulator to solve the problems raised in the above background art. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a multi-station feeding manipulator to solve the following technical problems:

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to the attached Figures 1 to 6As shown in the figure, a multi-station feeding manipulator in an embodiment of the present utility model includes a back plate 1. A transfer mechanism 2 is provided on the front end face of the back plate 1. The transfer mechanism 2 includes a guide rail 25. The lower end of the guide rail 25 is fixedly connected to a mounting plate 3. A blanking gripper 5 and a feeding gripper 4 are respectively fixedly connected to the left and right sides of the front end face of the mounting plate 3. The provided blanking gripper 5 and feeding gripper 4 can both adopt pneumatic grippers for blanking and feeding respectively.

[0031] The transfer mechanism 2 further includes a substrate 21 fixedly connected to the middle of the front end face of the back plate 1. A guide groove 22 is provided on the front end face of the substrate 21. A connecting rod 23 is rotatably connected to the inner side of the substrate 21. A rolling seat 24 is slidably connected between the outer end of the connecting rod 23 and the guide groove 22. The outer end of the rolling seat 24 is fixedly connected to the guide rail 25. When the connecting rod 23 rotates, it drives the rolling seat 24 to move along the guide groove 22. Since the rolling seat 24 is fixedly connected to the guide rail 25, it will drive the guide rail 25 to move along the trajectory of the guide groove 22 together.

[0032] An upper transition gripper 6 is fixedly connected to the middle of the front end face of the mounting plate 3. A support plate 7 is provided below the upper transition gripper 6. A lower transition gripper 8 is fixedly connected to the upper end of the support plate 7. The capacitor on the cleaning station is removed by the provided upper transition gripper 6 and placed on the lower transition gripper 8, which is convenient for detecting the capacitor. If it is detected as a defective product, the lower transition gripper 8 can be controlled to release, and the capacitor will fall out, thereby eliminating the defective product. If the detection is qualified, the lower transition gripper 8 will continue to hold and wait for the blanking gripper 5 to pick it up for blanking.

[0033] Sliding rails 26 are fixedly connected to both the upper and lower sides of the front end face of the substrate 21. The outer ends of the sliding rails 26 are slidably sleeved with a transverse sliding seat 27. A vertical sliding seat 28 is fixedly connected to the middle of the front end face of the transverse sliding seat 27. The guide rail 25 is slidably sleeved between the two vertical sliding seats 28. Through the provided transverse sliding seat 27 and vertical sliding seat 28, the guide rail 25 can move stably and smoothly in two axial directions.

[0034] The connecting rod 23 includes a rod body 231. A through groove 232 is provided at the outer end of the rod body 231. The rolling seat 24 includes a seat body 241. An inner roller 242 and an outer roller 243 are coaxially rotatably connected to the lower end of the inner side of the seat body 241. The seat body 241 is fixedly connected to the guide rail 25. The inner roller 242 is slidably connected to the inner wall of the guide groove 22. The outer roller 243 is slidably connected to the through groove 232. Through the provided inner roller 242 and outer roller 243, when the connecting rod 23 rotates, it can drive the seat body 241 to move, thereby driving the guide rail 25 to move along the guide groove 22.

[0035] The transfer mechanism 2 further includes a servo motor 29 fixedly connected to the rear end face of the back plate 1. The output end of the servo motor 29 is fixedly connected to the shaft end of the connecting rod 23. The provided servo motor 29 provides power to drive the connecting rod 23 to rotate.

[0036] On both sides of the connection between the guide rail 25 and the rolling seat 24, there are fixedly connected shielding strips 14. On both sides of the substrate 21, there are fixedly connected side plates 11. On the lower sides of the outer ends of the two side plates 11, there are fixedly connected limit switches one 12. Above the limit switch one 12 close to the feeding gripper 4, there is fixedly connected a limit switch two 13. Both the limit switch one 12 and the limit switch two 13 are opposed photoelectric switches. When the guide rail 25 moves to the leftmost and rightmost positions, the shielding strip 14 will block the limit switch one 12, causing the servo motor 29 to stop operating and preventing overrun. When the set limit switch two 13 is blocked, the rotation speed of the servo motor 29 decreases, facilitating the alignment and clamping of the material.

[0037] On both sides of the rear end face of the back plate 1, there are fixedly connected support frames 9. The front end face of the back plate 1 is fixedly covered with a protective shell 10. The upper and lower end faces of the protective shell 10 are in an open state. The provided protective shell 10 is used to protect the internal structure and improve safety. The provided support frames 9 facilitate the installation and fixation of the back plate 1.

[0038] The guide groove 22 is an inverted U-shaped groove. The inverted U-shaped guide groove 22 causes the rolling seat 24 to perform a process of first rising, then moving horizontally, and finally descending in an arc when moving along the guide groove 22, thereby realizing the lifting and moving of the gripper.

[0039] Working principle: Initially, the connecting rod 23 rotates to the leftmost position. The feeding gripper 4, the upper transition gripper 6, and the discharging gripper 5 are respectively located at the cleaning station, above the lower transition gripper 8, and the discharging station. The servo motor 29 starts and drives the connecting rod 23 to rotate to the right. When the connecting rod 23 rotates, it drives the rolling seat 24 to move along the guide groove 22. Since the guide groove 22 is an inverted U-shaped groove, the rolling seat 24 will perform a process of first rising, then moving horizontally, and finally descending in an arc during the movement to the rightmost position. Since the rolling seat 24 is fixedly connected to the guide rail 25, it will drive the guide rail 25 to move along the trajectory of the guide groove 22 together, thereby moving each gripper on the mounting plate 3 to the appropriate positions. The feeding gripper 4, the upper transition gripper 6, and the discharging gripper 5 respectively move above the feeding station, the cleaning station, and the lower transition gripper 8. Then each gripper closes to clamp the material. The servo motor 29 rotates in reverse, and each gripper resets to release the material, thus completing one feeding action.

[0040] The above has described an embodiment of the present invention in detail, but the content described is only the preferred embodiment of the present invention and cannot be considered as used to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
