Thus, features defined with "first" and "second" may explicitly or implicitly include one or more features.

[0041] The following disclosure provides many different implementations or examples for carrying out different structures of this application. To simplify the disclosure of this application, the components and arrangements of specific examples are described below. Of course, these are merely examples and are not intended to limit this application.

[0042] During the manufacturing process of the battery pack, the front and rear pressure strips need to be welded to the casing separately. Due to the limitations of the welding equipment, after one of the front and rear pressure strips is welded, the casing or tooling needs to be manually rotated 180° before the other one can be welded.

[0043] However, manual rotation is inefficient and can result in either incomplete or excessive rotation, leading to weld point misalignment and poor welding quality.

[0044] To address the technical problems of low efficiency and potential for incomplete or excessive rotation leading to weld misalignment and poor welding yield associated with manual rotation of the fixture or housing, the first embodiment of this application provides a positioning fixture. Please refer to [link to relevant documentation]. Figure 1 and Figure 2 The positioning fixture includes a base 100, a rotating assembly 200, a driving assembly 300, and a positioning assembly 400. The rotating assembly 200 is rotatably connected to the base 100 and has multiple positioning holes 211. The driving assembly 300 is disposed on the base 100 and connected to the rotating assembly 200, and the driving assembly 300 can drive the rotating assembly 200 to rotate. The positioning assembly 400 includes a driving part 410 and a moving part 420 connected to each other. The driving part 410 is connected to the base 100, and the moving part 420 can move away from the base 100 and pass through the positioning holes 211 to limit the rotation of the rotating assembly 200.

[0045] In some embodiments, the rotating assembly 200 is used to support the housing, and the driving assembly 300 drives the rotating assembly 200 to rotate, so that the rotating assembly 200 drives the housing to rotate.

[0046] In some embodiments, the rotating assembly 200 includes a first clamp group 240 and a second clamp group 250, which are used to clamp the front end pressure strip and the rear end pressure strip, respectively.

[0047] In some embodiments, the positioning component 400 is one or more of an electric cylinder, a pneumatic cylinder, or a hydraulic cylinder.

[0048] Firstly, in the above embodiments, by setting the drive component 300 to drive the rotation component 200 to rotate, the rotation efficiency of the housing can be improved; at the same time, the drive component 300 can rotate more precisely than manually, improving the accuracy of rotation, reducing the possibility of low welding yield due to solder joint misalignment, and improving the welding yield.

[0049] Secondly, in the above embodiment, by setting the positioning component 400 to extend into the positioning hole 211 after the rotating component 200 has rotated to its position, this action can serve as confirmation that the rotating component 200 has rotated to its position, so as to proceed to the next step, thereby reducing the possibility of low welding yield due to solder joint misalignment; at the same time, the positioning component 400 extending into the positioning hole 211 can also restrict the rotation of the rotating component 200 that has already rotated to its position, thereby further reducing the possibility of low welding yield due to solder joint misalignment caused by the rotation of the rotating component 200 during the welding process, and improving the welding yield.

[0050] Thirdly, since different pressure strips need to be welded, the rotating component 200 needs to stop at multiple different positions so that the welding robot can weld different pressure strips. In the above embodiment, by setting multiple positioning holes 211, the positioning component 400 can confirm the stopping position of the rotating component 200 when the rotating component 200 stops at different positions, and restrict the rotation of the rotating component 200 after it stops, thereby further improving the welding effect.

[0051] In some embodiments, the rotating assembly 200 includes a guide sleeve having the positioning hole 211. Specifically, in some embodiments, the guide sleeve passes through the support member 210, and the dimension of the guide sleeve along the thickness direction of the support member 210 is greater than the thickness of the support member 210, so as to extend the dimension of the contact surface between the positioning assembly 400 and the hole wall of the positioning hole 211 in the thickness direction of the support member 210, thereby making the positioning effect of the positioning assembly 400 on the rotating assembly 200 better.

[0052] In some embodiments, please refer to Figure 1 The positioning fixture includes multiple positioning components 400; the movable part 420 of each positioning component 400 can be inserted into a positioning hole 211.

[0053] In some embodiments, each positioning component 400 is symmetrical about the rotation axis of the rotating component 200.

[0054] In some embodiments, each positioning hole 211 is symmetrical about the rotation axis of the rotating assembly 200.

[0055] In some embodiments, the number of positioning holes 211 is equal to the number of positioning components 400.

[0056] In some embodiments, the rotating assembly 200 has two positioning holes 211 that are symmetrical about the rotation axis. The positioning fixture includes two positioning components 400 that are symmetrical about the rotation axis of the rotating assembly 200. Each of the two positioning components 400 can be inserted into one of the two positioning holes 211 when the front end pressure bar is welded, and into the other of the two positioning holes 211 when the rear end pressure bar is welded.

[0057] In the above embodiments, by setting multiple positioning components 400, the positioning effect of the rotating component 200 is further improved, thereby improving the welding yield of welding using the positioning fixture.

[0058] In some embodiments, please refer to Figure 3 and 4 The positioning fixture also includes a sensing component 500, which is used to identify the position of the rotating component 200 and adjust the rotation speed of the rotating component 200.

[0059] In some embodiments, the sensing component 500 may be one or more of a proximity switch, a limit switch, or a limit block 560, to adjust the rotation speed of the rotating component 200 at different positions.

[0060] In some embodiments, the sensing component 500 can be triggered by the rotating component 200 and feed back a signal, so that the driving component 300 changes the rotation speed of the rotating component 200 and also changes the rotation direction of the rotating component 200.

[0061] In some embodiments, adjusting the rotation speed of the rotating component 200 includes causing the rotating component 200 to start rotating so that the angular velocity of the rotating component 200 is greater than zero, and causing the rotating component 200 to stop rotating so that the angular velocity of the rotating component 200 is equal to zero.

[0062] In the above embodiment, by setting the sensing component 500 to introduce feedback adjustment, the movement of the rotating component 200 is made more precise, further reducing the possibility of low welding yield due to solder joint offset.

[0063] In some embodiments, please refer to Figure 5 , Figure 5This is a schematic diagram of the rotating assembly in the first working position. The sensing component 500 in box C is the first sensing component 510, and the sensing component 500 in box D is the second sensing component 520. The positioning fixture includes multiple sensing components 500, including the first sensing component 510 and the second sensing component 520. The first sensing component 510 is used to identify the position of the rotating assembly 200 when it rotates along the first rotation direction X and adjust the rotation speed of the rotating assembly 200. The second sensing component 520 is used to identify the position of the rotating assembly 200 when it rotates along the second rotation direction Y and adjust the rotation speed of the rotating assembly 200. The first rotation direction X and the second rotation direction Y are opposite.

[0064] In some embodiments, the first rotation direction X is the counterclockwise arrow direction in the accompanying drawings, and the second rotation direction Y is the clockwise arrow direction in the accompanying drawings; in other embodiments, the first rotation direction X is the clockwise arrow direction, and the second rotation direction is the counterclockwise arrow direction. The following description will use the first rotation direction X being the counterclockwise arrow direction in the accompanying drawings, and the second rotation direction Y being the clockwise arrow direction in the accompanying drawings.

[0065] Since the rotating component 200 has at least two working positions, in the above embodiment, the first sensing component 510 and the second sensing component 520 are provided to identify the rotating component 200 at two different positions and adjust the rotation speed of the rotating component 200, so that the rotating component 200 can stop precisely at different positions. This reduces the possibility of low welding yield due to solder joint drift when the rotating component 200 is in any position.

[0066] In some embodiments, please refer to Figure 6 and Figure 7 The sensing component 500 includes a work position detection element 530, which is connected to the base 100; the rotating component 200 has a work position, and when the rotating component 200 rotates to the work position, the rotating component 200 can trigger the work position detection element 530 to stop the driving component 300.

[0067] In some embodiments, the rotating assembly 200 includes a trigger 260.

[0068] Specifically, when the rotating component 200 is in the working position, the working position detection component 530 can detect the trigger component 260 and generate a feedback signal, which enables the drive component 300 to stop power output, thereby causing the rotating component 200 to stop at the preset working position.

[0069] In some embodiments, the working position detection element 530 in the first sensing component 510 is a first working detection element 531, which generates a feedback signal when the rotating component 200 is in a first working position, causing the drive component 300 to stop outputting power, thereby stopping the rotating component 200 at the first working position; the working position detection element 530 in the second sensing component 520 is a second working detection element 532, which generates a feedback signal when the rotating component 200 is in a second working position, causing the drive component 300 to stop outputting power, thereby stopping the rotating component 200 at the second working position. In some embodiments, the first working position is used for welding the front end pressure strip, and the second working position is used for welding the rear end pressure strip.

[0070] In the above embodiment, by setting the work position detection component 530, the power source of the rotating component 200 is cut off after the rotating component 200 rotates to the position, so that the rotating component 200 can stop at the position required for the welding work, thereby reducing the technical problem of low welding yield caused by weld point misalignment.

[0071] In some embodiments, please refer to Figure 6 and Figure 7 The sensing component 500 also includes a transition position detection element 540, which is connected to the base 100. Along the rotation direction of the rotating component 200, the rotating component 200 also has a transition position. When the rotating component 200 rotates to the transition position, the rotating component 200 can trigger the transition position detection element 540 to decelerate the drive component 300.

[0072] Specifically, as the rotating component 200 rotates toward the working position, it passes through a transition position. When the rotating component 200 is in the transition position, the transition position detection component 540 can detect the trigger component 260 and generate a feedback signal. The drive component 300 can reduce the power output, thereby enabling the rotating component 200 to decelerate and slowly reach the working position.

[0073] In some embodiments, the transition position detection element 540 in the first sensing component 510 is a first transition detection element 541, which generates a feedback signal when the rotating component 200 is in a first transition position, so that the driving component 300 reduces the power output, thereby causing the rotating component 200 to slowly reach the first working position; the transition position detection element 540 in the second sensing component 520 is a second transition detection element 542, which generates a feedback signal when the rotating component 200 is in a second transition position, so that the driving component 300 reduces the power output, thereby causing the rotating component 200 to slowly reach the second working position.

[0074] The first transition position is the transition position that the rotating component 200 will pass through when it rotates from the second working position to the first working position; the second transition position is the transition position that the rotating component 200 will pass through when it rotates from the first working position to the second working position.

[0075] In some embodiments, when the rotating assembly 200 rotates from the first working position to the second working position, the rotating assembly 200 rotates along the second rotation direction Y. When it rotates from the second working position to the first working position, the rotating assembly 200 rotates along the first rotation direction X. That is, along the first rotation direction X, the first transition detection element 541 is located between the second transition detection element 542 and the first working detection element 531.

[0076] In some other embodiments, the rotating assembly 200 rotates only in one direction of rotation, and the first transition detection element 541 and the second transition detection element 542 are oriented at an azimuth angle of 180° about the rotation axis of the rotating assembly 200. That is, along the rotation direction, the first working detection element 531 is located between the first transition detection element 541 and the second transition detection element 542, the second working detection element 532 is located between the first transition detection element 541 and the second transition detection element 542, and the first transition detection element 541 is located between the first working detection element 531 and the second working detection element 532.

[0077] In the above embodiment, by setting a transition position detection element 540 to decelerate the rotating component 200 when it is about to reach the working position, the possibility of weld point displacement caused by the rotation transition of the rotating component 200 is reduced, thereby improving the welding yield.

[0078] In some embodiments, please refer to Figure 6 and Figure 7 The positioning fixture also includes a sensor 550, which is connected to the base 100. Along the rotation direction of the rotating assembly 200, the sensor 550 is located on the side of the working position detection element 530 away from the transition position detection element 540. The rotating assembly 200 can trigger the sensor 550 to stop the drive assembly 300.

[0079] In some embodiments, the sensing element 550 is a limit switch. After the rotating component 200 contacts the limit switch, the limit switch can detect the trigger element 260 and generate a feedback signal. The driving component 300 can stop the power output, thereby causing the rotating component 200 to stop at a preset working position.

[0080] It is understandable that, since the sensor 550 is located on the side of the working position detection element 530 away from the transition position detection element 540, when the sensor 550 detects the rotating component 200, the rotating component 200 has already rotated excessively.

[0081] Specifically, over-rotation means that the rotating component 200 has rotated to the working position but has not stopped in time, thus missing the working position.

[0082] In some embodiments, the sensor 550 in the first sensing component 510 is a first sensor 551, which generates a feedback signal when the rotating component 200 misses the first working position and over-rotates, so that the drive component 300 stops power output, thereby reducing the degree of over-rotation of the rotating component 200. Along the first rotation direction X, the first sensor 551 is located on the side of the first working detection component 531 away from the first transition detection component 541. The sensor 550 in the second sensing component 520 is a second sensor 552, which generates a feedback signal when the rotating component 200 misses the second working position and over-rotates, so that the drive component 300 stops power output, thereby reducing the degree of over-rotation of the rotating component 200. Along the second rotation direction Y, the second sensor 552 is located on the side of the second working detection component 532 away from the second transition detection component 542.

[0083] In the above embodiment, by providing the sensing element 550, the degree of excessive rotation of the rotating component 200 can be reduced, the degree of solder joint offset can be reduced, and the impact of solder joint offset on the welding yield can be reduced.

[0084] In some embodiments, please refer to Figure 6 and Figure 7 The positioning fixture also includes a limiting block 560, which is connected to the base 100. Along the rotation direction of the rotating assembly 200, the limiting block 560 is located on the side of the working position detection element 530 away from the transition position detection element 540, and the rotating assembly 200 can contact the rotating assembly 200 and restrict the rotating assembly 200 from rotating in the rotation direction.

[0085] In some embodiments, the positioning fixture includes a plurality of limiting blocks 560, namely a first limiting block 561 and a second limiting block 562; wherein, the first limiting block 561 is used to prevent the rotating assembly 200 from continuing to rotate when the rotating assembly 200 misses the first working position and rotates excessively, thereby reducing the degree of excessive rotation of the rotating assembly 200, and the first limiting block 561 is located on the side of the first working detection member 531 away from the first transition detection member 541 along the first rotation direction X; the second limiting block 562 is used to prevent the rotating assembly 200 from continuing to rotate when the rotating assembly 200 misses the second working position and rotates excessively, thereby reducing the degree of excessive rotation of the rotating assembly 200, and the second limiting block 562 is located on the side of the second working detection member 532 away from the second transition detection member 542 along the second rotation direction Y.

[0086] In the above embodiment, by setting the limit block 560, the rotation component 200 can be restricted from continuing to rotate after it has rotated excessively, thereby reducing the degree of excessive rotation and reducing the impact of solder joint offset on the welding yield.

[0087] In some embodiments, please refer to Figure 6 and Figure 7 The limiting block 560 is disposed on the side of the sensing element 550 away from the working position detection element 530 along the rotation direction, so that when the sensing element 550 acts as the first safety barrier for excessive rotation, the limiting block 560 acts as the second safety barrier.

[0088] Specifically, the first limiting block 561 is disposed along the first rotation direction X on the side of the first sensing element 551 away from the first work detection element 531, as a second safety measure for the rotating assembly 200 in the first work position; the second limiting block 562 is disposed along the second rotation direction Y on the side of the second sensing element 552 away from the second work detection element 532, as a second safety measure for the rotating assembly 200 in the second work position.

[0089] In some embodiments, please refer to Figure 3 and Figure 5 The rotating assembly 200 includes a first rotating member 220, a second rotating member 230, and a support member 210; the second rotating member 230 is sleeved on the first rotating member 220 and rotatably connected to the first rotating member 220; the support member 210 is disposed on the side of the first rotating member 220 opposite to the base 100; of the first rotating member 220 and the second rotating member 230, one is connected to the base 100, and the other is connected to the support member 210.

[0090] The drive assembly 300 includes a driver 310 and a transmission member 320. The driver 310 is connected to the base 100. The transmission member 320 is connected to the driver 310 and is connected to one of the first rotating member 220 and the second rotating member 230. The driver 310 can drive the transmission member 320 to rotate, thereby causing one of the first rotating member 220 and the second rotating member 230 to rotate.

[0091] In some embodiments, the first rotating member 220 and the second rotating member 230 are the inner ring and outer ring of the bearing, respectively.

[0092] In some embodiments, the first clamp group 240 and the second clamp group 250 are respectively connected to the support member 210, which is used to support the box body.

[0093] In some embodiments, the driver 310 is a geared motor.

[0094] In some embodiments, the transmission member 320 is a gear, and the transmission member 320 meshes with the first rotating member 220 or the second rotating member 230.

[0095] In some embodiments, the transmission member 320 is disposed inside the first rotating member 220 and engages with the inner surface of the first rotating member 220 to drive the first rotating member 220 to rotate relative to the second rotating member 230; the second rotating member 230 is connected to the base 100, and the first rotating member 220 is connected to the support member 210.

[0096] In some embodiments, the trigger 260 is connected to the support 210 on the side near the base 100.

[0097] In the above embodiments, by setting a first rotating member 220 and a second rotating member 230 and causing the driving component 300 to drive one of the first rotating member 220 and the second rotating member 230 to rotate, the rotation of the rotating component 200 is made more stable. This improves the reliability of the positioning fixture, reduces the possibility of relative movement between the housing and the support member 210, which could cause the weld point to shift, and improves the welding yield.

[0098] In some embodiments, the drive assembly 300 further includes a connector 340 connected to the side of the base 100 away from the support member 210. The driver 310 is fixed to the side of the connector 340 away from the base 100. A portion of the driver 310 passes through the base 100 and is connected to the transmission member 320, so that most of the driver 310 can be located on the side of the base 100 away from the support member 210, thereby reducing the distance between the support member 210 and the base 100 and reducing the volume of the positioning fixture.
