Description

Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a pin welding tool. Background Art

[0002] In the battery production process, battery pin welding is an indispensable production process. In practice, there are hundreds of battery pin models, and the structures and shapes are also ever-changing. Due to the wide variety of products and small demand, most of them are welded to the metal bottom surface manually. During manual welding, the pole piece is prone to shaking, which can easily lead to welding misalignment and the welding quality cannot be guaranteed. It also consumes manpower and has low production efficiency. Utility Model Content

[0003] The utility model aims to provide a pin welding tool, which can realize automatic welding of pins and greatly improve production efficiency and welding quality.

[0004] A pin welding tool comprises a workbench, a rotating disk, and a rotating driving member, wherein the rotating driving member is arranged on the workbench, the rotating disk is connected to the rotating driving member, and the rotating driving member can drive the rotating disk to rotate. The rotating disk has a plurality of clamps arranged at equal angles along its circumference, and the rotating disk is respectively provided with a pick-up and placement station and a welding station on both sides along its radial direction. When the clamp reaches the pick-up and placement station and the welding station, the rotating disk stops rotating. The clamp comprises a connecting frame, a pin placement block, and a clamping block. The connecting frame is connected to the rotating disk, the pin placement block is connected to the connecting frame, the pin placement block is provided with a groove body for placing pins, and the clamping block is rotatably connected to the pin placement block so that the clamping block approaches or moves away from the pin.

[0005] In the above technical solution, by setting the pick-up and place stations and the welding stations on both sides of the radial direction of the rotating disk, when the fixture reaches the pick-up and place stations and the welding stations, the rotating disk stops rotating, and the welder welds the pins on the fixture at the welding station. At the same time, the staff takes out the welded pins placed on the pick-up and place stations, and places new pins on the pick-up and place stations. The rotating disk continues to rotate, and the above actions are repeated. The utility model realizes the automatic welding of pins and improves production efficiency.

[0006] Furthermore, the slot body includes a horizontal slot and a vertical slot, and the vertical slot is arranged on a side of the pin placement block facing the clamping block.

[0007] In the above technical solution, since the pin is L-shaped, the pin placement block is provided with corresponding horizontal grooves and vertical grooves to facilitate the placement of the pin, so that the pin fits the pin placement block more closely, ensuring the welding quality. At the same time, the vertical groove is provided on the side of the pin placement block facing the clamping block, which is beneficial for the clamping block to limit the pin, thereby further improving the stability of the pin.

[0008] Furthermore, the welding station is provided with a galvanometer, and the galvanometer is mounted above the rotating disk.

[0009] In the above technical solution, the galvanometer can magnify the image of the pin, making the pin more clearly visible, and further improving the quality and accuracy of welding.

[0010] Furthermore, the pick-and-place station is provided with a mounting seat, and the mounting seat is provided with a detection sensor.

[0011] In the above technical solution, the detection sensor is used to sense the presence or absence of pins. When the detection sensor detects that there are no pins placed on the horizontal groove, the rotating disk does not rotate, thereby avoiding welding errors and damaging the entire tooling.

[0012] Furthermore, the pick-and-place station is also provided with a clamping drive member, and the clamping drive member is opposite to the mounting seat. When the clamp reaches the pick-and-place station, the clamping drive member drives the clamping block to rotate.

[0013] In the above technical solution, the clamping drive is used to drive the clamping block to rotate. When the clamp reaches the pick-and-place station, the clamping drive pushes the clamping block to rotate, so that the clamping block is away from the pin, making it convenient for the staff to take out and place new pins.

[0014] Furthermore, the clamping block is provided with a boss, and the pin placement block is provided with a slot corresponding to the boss.

[0015] In the above technical solution, when the staff places a new pin in the horizontal groove, the clamping drive releases the restriction on the clamping block. At this time, the boss extends into the slot to ensure that the clamping block can clamp the pin, so that the pin is not easy to shake under the restriction of the clamping block during welding.

[0016] Furthermore, the workbench is also provided with a display.

[0017] In the above technical solution, the display is mainly used to display data such as current and voltage, helping the staff to timely understand the working status of the welding machine during the welding process and adjust the welding parameters as needed. This can make the welding process more stable and accurate, and improve the welding quality and efficiency.

[0018] Furthermore, the pin placement block is made of brass.

[0019] In the above technical solution, the pin placement block is made of brass, and the pin material is copper-nickel alloy, which is a metal material and is silver-white in color. The use of brass material not only increases the wear resistance of the clamp, but also makes it easy to distinguish the color from the material, making it easier for staff to observe whether the pin is placed in place during operation.

[0020] Compared with the prior art, the beneficial effects of the utility model are: by setting a rotating disk and a clamp, the rotating drive part drives the rotating disk to drive the clamp to rotate, so that the clamp reaches the welding station and the pick-and-place station to weld the pins. At the same time, the staff takes out the welded pins and places new pins on the clamp. The overall operation is simple and convenient, the work efficiency is high, the equipment runs reliably, and a good technical effect is achieved. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The pin welding tool of the present invention will be further described in detail below in conjunction with specific embodiments and drawings. The drawings show preferred embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0029] Please also refer to Figure 1 and Figure 2In a preferred embodiment, the pin welding tool of the utility model includes a workbench 1, a rotating disk 2, and a rotating driving member 3. The rotating driving member 3 is arranged on the workbench 1, and the rotating disk 2 is connected to the rotating driving member 3. The rotating driving member 3 can drive the rotating disk 2 to rotate. The rotating disk 2 has a plurality of clamps 4 arranged at equal angles along its circumference. The rotating disk 2 is respectively provided with a pick-up and placement station 201 and a welding station 202 on both sides of its radial direction. When the clamp 4 reaches the pick-up and placement station 201 and the welding station 202, the rotating disk 2 stops rotating, wherein the clamp 4 includes a connecting frame 401, a pin placement block 402, and a clamping block 403. The connecting frame 401 is connected to the rotating disk 2, and the pin placement block 402 is connected to the connecting frame 401. The pin placement block 402 is provided with a slot 4021 for placing the pin 5, and the clamping block 403 is rotatably connected to the pin placement block 402 so that the clamping block 403 is close to or away from the pin 5.

[0030] It can be seen from the above technical solution that by respectively setting the pick-up and place 201 and the welding station 202 on both sides of the rotating disk 2 in the radial direction, when the fixture 4 reaches the pick-up and place station 201 and the welding station 202, the rotating disk 2 stops rotating, and the welding machine welds the pins 5 on the fixture 4 at the welding station 202. At the same time, the staff takes out the welded pins 5 placed on the pick-up and place station 201, and places new pins 5 on the pick-up and place station 201. The rotating disk 2 continues to rotate and repeats the above actions. The utility model realizes the automatic welding of the pins 5 and improves the production efficiency.

[0031] It should be noted that the utility model can perform continuous welding operations, during which the staff only needs to place the pins directly on the clamp 4 for clamping, and the degree of automation is high.

[0032] In this embodiment, four groups of clamps 4 are provided, which are respectively arranged at four positions of the rotating disk 2, and there is a 90-degree angle between two adjacent clamps 4. In specific implementation, different numbers of clamps 4 can be set according to the size of the rotating disk 2 to improve work efficiency.

[0033] Please refer to Figure 3 The slot body 4021 includes a horizontal slot 4021a and a vertical slot 4021b. Specifically, the vertical slot 4021b is arranged on the side of the pin placement block 402 facing the clamping block 403. Since the pin 5 is L-shaped, the pin placement block 402 is provided with the corresponding horizontal slot 4021a and vertical slot 4021b, which not only makes the positioning of the pin 5 more accurate, and is convenient for the staff to take and place the pin without getting stuck and deformed, but also makes the pin 5 fit the pin placement block 402 more closely, ensuring the welding quality. At the same time, the vertical slot 4021b is arranged on the side of the pin placement block 402 facing the clamping block 403, which is conducive to the clamping block 403 to limit the pin 5, and further improves the stability of the pin 5.

[0034] Please refer to Figure 1 The welding station 202 is provided with a galvanometer 6, which is mounted above the rotating disk 2. When the rotating drive member 3 drives the rotating disk 2 to rotate and drives the clamp 4 to reach the welding station 202, the galvanometer 6 is vertically opposite to the horizontal slot 4021a. The galvanometer 6 can magnify the image of the pin 5, making the pin 5 more clearly visible, further improving the quality and accuracy of welding. When one of the clamps 4 reaches the welding station 202, the galvanometer 6 magnifies the pin 5 located on the horizontal slot 4021a, making the welding position of the pin 5 clearly visible, ensuring the welding quality.

[0035] Please also refer to Figure 2 and Figure 4 The pick-and-place station 201 is provided with a mounting seat 7, and the mounting seat 7 is provided with a detection sensor 8. When the fixture 4 arrives at the pick-and-place station 201, the detection sensor 8 is horizontally opposite to the horizontal groove 4021a. The detection sensor 8 is used to sense the presence or absence of the pin 5. When the detection sensor 8 detects that the pin 5 is not placed on the horizontal groove 4021a, the rotating disk 2 does not rotate, thereby avoiding welding errors and damaging the entire tooling; when the detection sensor 8 detects that the pin 5 is placed on the horizontal groove 4021a, the rotating disk 2 rotates, so that the welding work can proceed as usual. The setting of the detection sensor 8 not only helps the smooth progress of the welding work, but also ensures the safety of the utility model.

[0036] Please also refer to Figure 2 and Figure 4 The pick-and-place station 201 is also provided with a clamping drive 9, which is opposite to the mounting seat 7. When the clamp 4 reaches the pick-and-place station 201, the clamping drive 9 drives the clamping block 403 to rotate. The clamping drive 9 is used to drive the clamping block 403 to rotate. When the clamp 4 reaches the pick-and-place station 201, the clamping drive 9 pushes the clamping block 403 to rotate, so that the clamping block 403 is away from the pin 5, which is convenient for the staff to take out and place a new pin 5.

[0037] Please refer to Figure 5 The pin placement block 402 is connected to a clamping block 403 on one side facing the rotating disk 2. The clamping block 403 is provided with a boss 801, and the pin placement block 402 is provided with a slot 4022 corresponding to the boss 4031. When the pin 5 is placed in the slot 4021, the clamping block 403 is tightly attached to the pin placement block 402, and at the same time, the boss 4031 extends into the slot 4022, ensuring that the clamping block 403 can press the pin 5, so that the pin 5 is not easy to shake under the restriction of the clamping block 403 during welding.

[0038] Please refer to Figure 1The workbench 1 is also provided with a display 10. The display 10 is mainly used to display data such as current and voltage, so as to help the staff to timely understand the working status of the welding machine during the welding process and adjust the welding parameters as needed. This can make the welding process more stable and accurate, and improve the welding quality and efficiency.

[0039] It should be noted that the pin placement block 402 is made of brass. The pin placement block 402 is made of brass, and the pin 5 is made of copper-nickel alloy, which is a metal material and has a silvery white color. The use of brass material not only increases the wear resistance of the clamp 4, but also makes it easy to distinguish the color from the material, so that when the staff is operating, it is easier to observe whether the pin 5 is placed in place.

[0040] In this way, when it is necessary to weld the pin 5, it is only necessary to place the pin 5 on the slot body 4021, the clamping drive 9 drives the clamping block 403 to clamp the pin 5, and the rotating drive 3 drives the rotating disk 2 to rotate. When the clamp 4 reaches the pick-up and placement station 201 and the welding station 202, the rotating disk 2 stops, and the welder welds the pin 5. At the same time, the staff takes out the welded pin 5 and puts the new pin 5 into the slot body 4021. Moreover, due to the restrictions on the pin 5 by the slot body 4021 and the clamping block 403, the welding is more precise.
