[0013] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0014] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0015] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be used interchangeably where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0016] To make the objectives and advantages of the present invention clearer, the present invention will be further described below with reference to embodiments; it should be understood that the specific embodiments described herein are merely for explaining the present invention and are not intended to limit the present invention.

[0017] Please see Figures 1-11As shown, a positioning welding processing equipment for starting battery PCB circuit boards includes a support cabinet 1. The front end and both sides of the outer surface of the support cabinet 1 are movably installed with cabinet doors 101 via hinges. A support platform 102 is fixedly installed in the middle of the upper surface of the support cabinet 1. A first conveyor belt assembly 103 is fixedly installed in the front end of the upper surface of the support platform 102. A support frame 104 is fixedly installed in the middle rear end of the upper surface of the support platform 102. An electric telescopic rod 105 is fixedly installed in the upper surface of the other end of the support frame 104. It should be noted that by setting up the first conveyor belt assembly 103, the welding process of the battery pack 5 and the circuit board 6 is carried out above the first conveyor belt assembly 103. After the welding is completed, the finished product can be placed on the first conveyor belt assembly 103 for finished product transportation. The electric telescopic rod 105 is supported by the set support frame 104. The electric telescopic rod 105 extends and retracts with the support frame 104 as the fulcrum, so as to achieve the effect of adjusting the welding structure.

[0018] The output end of the electric telescopic rod 105 extends outward through the support frame 104. A support plate 2 is fixedly installed at the output end of the electric telescopic rod 105. Welding heads 201 are fixedly installed at both ends of the lower surface of the support plate 2. Welding rods 202 are inserted into the interface end of the welding heads 201. Wires 203 are provided at both ends of the upper surface of the support frame 104. The forked ends of the wires 203 pass through the support plate 2 and are electrically connected to the welding heads 201. The other end of the wires 203 passes through the support frame 104 and is electrically connected to a welding machine 205. The welding machine 205 is fixed to the rear end of the upper surface of the support platform 102. A spring sleeve 204 is fixedly installed on the outer surface of the end of the wires 203 near the support plate 2. It should be noted that the extension and retraction of the electric telescopic rod 105 can control the support plate 2 to move up and down. The movement of the support plate 2 drives the welding head 201 to control the welding rod 202 to weld the contact area between the electrode plate 501 and the welding point 601. The welding machine 205 can control the welding temperature of the welding rod 202 through the wire 203 in conjunction with the welding head 201. When the electric telescopic rod 105 controls the support plate 2 to move up and down, since one end of the wire 203 passes through the support plate 2 and is electrically connected to the welding head 201, the wire 203 will be stretched during the movement of the support plate 2. By setting a part of the wire 203 into a spring shape and covering the surface with a spring sleeve 204, the wire 203 can easily extend and retract with the movement of the support plate 2, so as to ensure the control effect of the welding machine 205 on the welding rod 202. Secondly, the electric telescopic rod 105 controls the descent distance of the support plate 2, which can be adjusted according to the wear length of the welding rod 202. If the first descent distance of the support plate 2 is 30mm and the wear length of the welding rod 202 is 3mm, then the second descent distance of the support plate 2 after returning to its original position is 33mm. And so on, the extension distance of the output end of the electric telescopic rod 105 is automatically adjusted according to the wear length of the welding rod 202.

[0019] The second conveyor belt assembly 3 and the third conveyor belt assembly 4 are fixedly installed on the upper two sides of the rear end of the outer surface of the support cabinet 1, respectively. The setting height of the second conveyor belt assembly 3 is higher than that of the third conveyor belt assembly 4, and the setting height of the third conveyor belt assembly 4 is higher than that of the first conveyor belt assembly 103. The second conveyor belt assembly 3 includes a conveyor belt. A plurality of first positioning block groups 301 are evenly distributed on the outer surface of the conveyor belt. A sleeve 302 is inserted and installed on the inner surface of each of the plurality of first positioning block groups 301. A battery pack 5 is inserted and installed through the lower surface of the sleeve 302. An electrode plate 501 is electrically connected to the lower surface of the battery pack 5. Welding holes are opened through the two ends of the upper surface of the electrode plate 501. The third conveyor belt assembly 4 includes a conveyor belt. A plurality of second positioning block groups 401 are evenly distributed on the outer surface of the conveyor belt. A support sleeve 402 is inserted and installed on the inner surface of each of the plurality of second positioning block groups 401. A circuit board 6 is embedded in the upper surface of the support sleeve 402. Solder points 601 are provided on both sides of the front end of the upper surface of the circuit board 6. It should be noted that the battery pack 5 and the circuit board 6 are transported by the second conveyor belt assembly 3 and the third conveyor belt assembly 4 respectively. By fitting the sleeve 302 on the outside of the battery pack 5 and connecting the sleeve 302 with the first positioning block assembly 301, the stability of the battery pack 5 on the second conveyor belt assembly 3 can be ensured. At the same time, when positioning and clamping the battery pack 5, the outer sleeve 302 can be clamped, which can ensure the clamping effect and avoid processing damage to the battery pack 5 body. By embedding the circuit board 6 on the upper surface of the support sleeve 402 and connecting the support sleeve 402 with the second positioning block group 401, the stability of the circuit board 6 in the flow conveying on the third conveyor belt assembly 4 can be ensured. At the same time, when positioning and clamping the circuit board 6, the external support sleeve 402 can be clamped, which can ensure the clamping effect while avoiding processing damage to the circuit board 6 body. Since the second conveyor belt assembly 3 is set at a higher height than the third conveyor belt assembly 4, and the third conveyor belt assembly 4 is set at a higher height than the first conveyor belt assembly 103, the battery pack 5 will be higher than the circuit board 6 during the conveying process. Thus, the battery pack 5 is located above the circuit board 6 to ensure that the electrode sheet 501 is located above the solder joint 601 for superimposed welding. Next, the single conveying distance of the second conveyor belt assembly 3 and the third conveyor belt assembly 4 needs to be set. A retaining sleeve 302 is inserted inside the first positioning block group 301, and a support sleeve 402 is inserted inside the second positioning block group 401. At this time, the second conveyor belt assembly 3 is driven to convey the first positioning block group 301 with the retaining sleeve 302 into the first positioning frame 8. When the conveying stops, the rear end of the retaining sleeve 302 must be aligned with the open end of the first positioning frame 8. Simultaneously, the third conveyor belt assembly 4 is driven to convey the second positioning block group with the support sleeve 402... 401 is conveyed to the second positioning frame 9. When the conveying ends, the rear end of the support sleeve 402 needs to be aligned with the open end of the second positioning frame 9 to complete the starting point positioning of the single conveying distance. At this time, the first positioning frame 8 and the second positioning frame 9 can position and clamp the ferrule 302 and the support sleeve 402. After clamping, the first positioning frame 8 and the second positioning frame 9 need to be lifted to drive the ferrule 302 and the support sleeve 402 to disengage from the first positioning block group 301 and the second positioning block group 401 respectively. At this time, the turntable 7 can select and adjust the orientation. Once the starting point of a single conveying distance is determined, a retainer 302 is inserted again into the next first positioning block group 301 closest to the rear end of the first positioning block group 301. Simultaneously, a support sleeve 402 is inserted again into the next second positioning block group 401 closest to the rear end of the second positioning block group 401. At this point, the second conveyor belt assembly 3 and the third conveyor belt assembly 4 are driven again. When the conveying ends, the rear end of the retainer 302 must be aligned with the opening end of the first positioning frame 8, which is adjusted to the side of the second conveyor belt assembly 3, and the rear end of the support sleeve 402 must be aligned with the opening end of the second positioning frame 9, which is adjusted to the side of the third conveyor belt assembly 4. At this point, the ending point of a single conveying distance can be obtained. In this case, the distance between the starting point and the ending point is the single conveying distance of the second conveyor belt assembly 3 and the third conveyor belt assembly 4. The conveying distance of the second conveyor belt assembly 3 and the third conveyor belt assembly 4 is based on this distance for each conveying, thereby ensuring that the battery pack 5 and the circuit board 6 are accurately conveyed to the positioning clamping points of the first positioning frame 8 and the second positioning frame 9.

[0020] A turntable motor 106 is fixedly installed on both sides of the middle of the top surface of the support cabinet 1. A turntable 7 is rotatably inserted and installed on both sides of the middle of the upper surface of the support cabinet 1. The output end of the turntable motor 106 is fixedly connected to the middle of the lower surface of the turntable 7. A fixed plate 701 is set above the turntable 7. An adjusting motor 702 is fixedly installed on the middle of the four sides of the upper surface of the fixed plate 701. An adjusting screw 704 is rotatably installed on the middle of the four sides of the outer surface of the turntable 7 and the fixed plate 701. A limit frame 703 is set on both sides of the outer surface of the adjusting screw 704. The two ends of the limit frame 703 are fixedly connected to the outer surface of the turntable 7 and the fixed plate 701 respectively. A first positioning frame 8 in the shape of "U" is spirally sleeved on the outer surface of one adjusting screw 704, and a second positioning frame 9 in the shape of "U" is spirally sleeved on the outer surface of the other adjusting screw 704. It should be noted that the turntable 7 can be driven to rotate clockwise and counterclockwise by the turntable motor 106. When the turntable 7 with the first positioning frame 8 is rotating clockwise, the turntable 7 with the second positioning frame 9 needs to be rotating counterclockwise so that the first positioning frame 8 and the second positioning frame 9 can be adjusted to be stacked on top of each other. This ensures that the battery pack 5 positioned and clamped by the first positioning frame 8 is located above the circuit board 6 positioned and clamped by the second positioning frame 9, so as to realize the positioning and docking of the positive and negative terminals of the electrode plates 501 of the battery pack 5 with the solder joints 601 of the circuit board 6. The turntable motor 106 drives the turntable 7 to rotate by 90 degrees in one go. The adjusting screw 704 can be controlled to rotate clockwise and counterclockwise by adjusting the motor 702. The clockwise and counterclockwise rotation of the adjusting screw 704 controls the first positioning frame 8 and the second positioning frame 9 to move up and down along the limiting frame 703. During the adjustment process, the limiting frame 703 will limit the first positioning frame 8 and the second positioning frame 9 to prevent them from deviating. At the same time, when the first positioning frame 8 and the second positioning frame 9 rotate to the side close to the first conveyor belt assembly 103, the first positioning frame 8 and the second positioning frame 9 in the corresponding position need to be adjusted to the rising state, so that they can be stably positioned above the second conveyor belt assembly 3 and the third conveyor belt assembly 4 in subsequent position adjustments, thereby avoiding the second conveyor belt assembly 3 and the third conveyor belt assembly 4 from obstructing the rotation of the turntable 7.

[0021] Limiting plates 10 are fixedly installed on both sides of the upper surface of the first positioning frame 8 and the second positioning frame 9 near the adjusting screw 704. A motor 11 is fixedly installed in the middle of the upper surface of each limiting plate 10. A drive gear 12 is rotatably installed on one side of the upper surface of the limiting plate 10. The output end of the motor 11 is fixedly connected to the drive gear 12. A bidirectional screw 13 is rotatably installed through both sides of the inner surface of the first positioning frame 8 and the second positioning frame 9 near the adjusting screw 704. A drive gear is fixedly installed at the end of the bidirectional screw 13 near the drive gear 12. The driven gear 14 and the driven gear 14 are meshed with each other. The two ends of the middle part of the outer surface of the bidirectional screw 13 are screwed with clamping plates 15. The first positioning frame 8 has clamping plates 15 located on the upper part of both sides of the inner surface. The second positioning frame 9 has clamping plates 15 located on the lower part of both sides of the inner surface. The lower parts of the outer surfaces of the first positioning frame 8 and the second positioning frame 9 away from the adjusting screw 704 are both fixedly mounted with connecting blocks 16. The first positioning frame 8 is set to correspond to the second conveyor belt assembly 3. The second positioning frame 9 is set to correspond to the third conveyor belt assembly 4. It should be noted that by adjusting the screw 704 to rotate clockwise, the first positioning frame 8 can be controlled to descend with the second positioning frame 9. When the first positioning frame 8 on the side corresponding to the second conveyor belt assembly 3 descends above the second conveyor belt assembly 3, and the second positioning frame 9 on the side corresponding to the third conveyor belt assembly 4 descends above the third conveyor belt assembly 4, the motor 11 can be started to control the drive gear 12 to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotation of the drive gear 12 drives the driven gear 14 meshing with it to rotate counterclockwise and clockwise, thereby indirectly controlling the clockwise and counterclockwise rotation of the bidirectional screw 13. When the bidirectional screw 13 is in the clockwise rotation state, the clamping plates 15 can be controlled to be in the state of mutual closing and closeness. Thus, the clamping plates 15 are used to achieve positioning and clamping of the sleeve 302 and the support sleeve 402, and indirectly realize the positioning and clamping of the battery pack 5 and the circuit board 6 in the first positioning frame 8 and the second positioning frame 9 respectively for positioning and welding.

[0022] In use, after adjusting the single conveying distance of the second conveyor belt assembly 3 and the third conveyor belt assembly 4, the battery pack 5 with the sleeve 302 and the circuit board 6 with the support sleeve 402 are installed into the first positioning block group 301 and the second positioning block group 401 of the second conveyor belt assembly 3 and the third conveyor belt assembly 4, respectively. At this time, the adjusting motor 702 on one side of the second conveyor belt assembly 3 and the third conveyor belt assembly 4 is started to control the adjusting screw 704 to rotate clockwise. The clockwise rotation of the adjusting screw 704 controls the first positioning frame 8 and the second positioning frame 9 to move down along the limiting frame 703 until the first positioning frame 8 and the second positioning frame 9 are respectively lowered above the second conveyor belt assembly 3 and the third conveyor belt assembly 4. At this time, the second conveyor belt assembly 3 and the third conveyor belt assembly 4 can be started to convey the battery pack 5 and the circuit board 6 until the battery pack 5 and the circuit board 6 are conveyed to the designated positions in the first positioning frame 8 and the second positioning frame 9, respectively. At this point, the motor 11 can be started to control the drive gear 12 to rotate counterclockwise. The counterclockwise rotation of the drive gear 12 drives the driven gear 14, which meshes with it, to rotate clockwise, thereby indirectly controlling the clockwise rotation of the bidirectional screw 13. When the bidirectional screw 13 is in the clockwise rotation state, the clamping plates 15 can be controlled to be in a state of mutual closing and closeness. Thus, the clamping plates 15 are used to position and clamp the external sleeve 302 of the battery pack 5 and the external support sleeve 402 of the circuit board 6, thereby indirectly positioning and clamping the battery pack 5 and the circuit board 6 in the first positioning frame 8 and the second positioning frame 9 respectively. After clamping, the first positioning frame 8 and the second positioning frame 9 need to be lifted to drive the sleeve 302 of the battery pack 5 and the support sleeve 402 of the circuit board 6 to disengage from the first positioning block group 301 and the second positioning block group 401 respectively. At this time, the turntable 7 can be selected to adjust the orientation. Next, once the battery pack 5 and the circuit board 6 are both in the positioning and clamping state, the turntable motor 106 can be started to drive the turntable 7 of the first positioning frame 8 to rotate 90 degrees clockwise and drive the turntable 7 of the second positioning frame 9 to rotate 90 degrees counterclockwise. At this time, the first positioning frame 8 and the second positioning frame 9 clamping the battery pack 5 and the circuit board 6 will be oriented to be stacked vertically, thereby ensuring that the battery pack 5 positioned and clamped by the first positioning frame 8 is above the circuit board 6 positioned and clamped by the second positioning frame 9, so as to realize the positioning and docking of the positive and negative poles of the electrode plates 501 of the battery pack 5 corresponding to the solder points 601 of the circuit board 6. In this situation, the adjusting motor 702 on the side of the first positioning frame 8 near the second positioning frame 9 can be activated to control the adjusting screw 704 to rotate clockwise, thereby controlling the first positioning frame 8 to descend until the positive and negative ends of the electrode plate 501 of the battery pack 5 are superimposed and in contact with the solder joint 601 of the circuit board 6. At this time, the electric telescopic rod 105 can be activated to control the support plate 2 to descend. The descent of the support plate 2 drives the welding head 201 to control the welding end of the welding rod 202 to descend until the welding end of the welding rod 202 is in contact with the superimposed part of the electrode plate 501 and the solder joint 601. At this time, the welding machine 205 is activated in conjunction with the wire 203 to control the welding rod 202 to perform electric welding processing and connection on the electrode plate 501 and the solder joint 601, thereby realizing the welding connection between the battery pack 5 and the circuit board 6. Finally, after welding is completed, the electric telescopic rod 105 can control the support plate 2 to lift and separate the welding rod 202 from the weld point 601. At this time, the motor 11 on the side where the first positioning frame 8 and the second positioning frame 9 are superimposed is started to control the drive gear 12 to rotate clockwise. The clockwise rotation of the drive gear 12 drives the driven gear 14 meshing with it to rotate counterclockwise, thereby indirectly controlling the counterclockwise rotation of the bidirectional screw 13. When the bidirectional screw 13 is in the counterclockwise rotation state, the clamping plates 15 can be controlled to be in a state of mutual separation, so that the battery pack 5 and circuit board 6, which are positioned and clamped in the first positioning frame 8 and the second positioning frame 9, are placed on the first conveyor belt assembly 103. At this time, the first conveyor belt assembly 103 can transport and discharge the welded finished product. The battery pack 5 and circuit board 6 then repeat the above steps to achieve flowing positioning welding.

[0023] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
