Description

A lithium battery cap pressure welding device

Technical Field

The utility model relates to the technical field of lithium battery cap pressure welding, in particular to a lithium battery cap pressure welding device.

Background technique

Pressure welding of lithium battery caps refers to the process of connecting the positive and negative caps of the battery to the battery shell when assembling lithium batteries. Pressure welding is a commonly used connection technology that can ensure good electrical contact and mechanical connection between the positive and negative electrodes of the battery and the battery shell.

When the existing equipment is press-welding lithium batteries, the press-welding effect is often very unsatisfactory because the lithium batteries do not have a stable clamping force, and the press-welding may even fail completely, which is not conducive to the processing of lithium batteries. After the press-welding is completed, the staff needs to manually remove the press-welded lithium batteries, which causes a certain waste of labor resources.

Spring 5, the other ends of the two first springs 5 are respectively fixedly connected to the tops of the two sliding bars 303, a support plate 17 is fixedly installed on the top of the workbench 1, a hydraulic cylinder 18 is arranged at the bottom of the support plate 17, and the bottom of the hydraulic cylinder 18 is fixedly connected to the top of the pressure welding rod 2. By setting the limiting mechanism 3, the staff starts the hydraulic cylinder 18 to move the pressure welding rod 2 downward, driving the connecting plate 301 to move downward. Since the height of the bottom of the sliding bar 303 is lower than the height of the bottom of the pressure welding rod 2, the limiting rod 304 is firstly in contact with the processed battery. Due to the squeezing of the battery, the limiting rod 304 drives the sliding bar 303 to retract into the inside of the limiting groove 302, and compresses the first spring 5 at the same time. Due to the rebound force of the first spring 5, the battery is conveniently limited;

1-4, the unloading mechanism 4 includes a support frame 401, an unloading frame 402 and a blocking frame 403, the support frame 401 is slidably mounted on the top of the workbench 1, the unloading frame 402 is rotatably mounted inside the support frame 401, the blocking frame 403 is fixedly mounted on the top of the workbench 1, a fixing plate 6 is fixedly mounted on the right side of the support frame 401, two second springs 7 are fixedly mounted on the top of the fixing plate 6, the other side of the second spring 7 is fixedly connected to the bottom of the unloading frame 402, a storage box 8 is provided on the top of the workbench 1, a fixing block 9 is fixedly mounted on the top of the workbench 1, a third spring 10 is fixedly mounted on the right side of the fixing block 9, the other end of the third spring 10 is fixedly connected to the left side of the support frame 401, a turntable 11 is rotatably mounted on the top of the workbench 1, a receiving ring 12 is fixedly mounted on the top of the turntable 11, a motor 13 is fixedly mounted inside the workbench 1, and the output end of the motor 13 is fixedly connected to the bottom of the turntable 11. The output end of the motor 13 is sleeved with a rotating blade 14, and a slide groove 15 is provided on the top of the workbench 1. A slider 16 is slidably installed inside the slide groove 15. The top of the slider 16 is fixedly connected to the bottom of the support frame 401. By setting the unloading mechanism 4, the staff starts the motor 13 to drive the turntable 11 to rotate, and drives the rotating blade 14 to rotate through the connection relationship with the rotating blade 14. Since the rotating blade 14 squeezes the slider 16, the slider 16 moves to a position away from the central axis of the workbench 1 through the cooperation of the slide groove 15, thereby driving the support frame 401 to move. Due to the squeezing of the stop frame 403, the unloading frame 402 rotates, and the second spring 7 is compressed at the same time. When the unloading frame 402 is flush with the stop frame 403, it continues to move to the left, and the third spring 10 is compressed at the same time, so that the battery after pressure welding is pulled into the storage box 8. When reaching the preset position, the rotating blade 14 is no longer in contact with the slider 16, and the unloading frame 402 and the support frame 401 return to their original positions through the rebound force of the second spring 7 and the third spring 10.

Specifically, the working process or working principle of the lithium battery cap pressure welding device is as follows: when in use, the staff starts the hydraulic cylinder 18 to move the pressure welding rod 2 downward, driving the connecting plate 301 to move downward. Since the height of the bottom of the sliding rod 303 is lower than the height of the bottom of the pressure welding rod 2, the limiting rod 304 first contacts the processed battery. Due to the squeezing of the battery, the limiting rod 304 drives the sliding rod 303 to retract into the limiting groove 302, and at the same time compresses the first spring 5. Due to the rebound force of the first spring 5, the battery is conveniently limited. The motor 13 is started to drive the turntable 11 to rotate, and the rotating blade 14 is connected to drive the rotating blade 14 to rotate. The rotating blade 14 rotates, and the rotating blade 14 squeezes the slider 16. Through the cooperation of the slide groove 15, the slider 16 moves to a position away from the central axis of the workbench 1, thereby driving the support frame 401 to move. Due to the squeezing of the retaining frame 403, the unloading frame 402 rotates and compresses the second spring 7 at the same time. When the unloading frame 402 is flush with the retaining frame 403, it continues to move to the left and compresses the third spring 10 at the same time, thereby pulling the pressure-welded battery into the storage box 8. When reaching the preset position, the rotating blade 14 and the slider 16 are no longer in contact, and the rebound force of the second spring 7 and the third spring 10 returns the unloading frame 402 and the support frame 401 to their original positions.

It should be noted that the motor 13, the welding rod 2 and the hydraulic cylinder 18 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
