Description

Technical Field

[0001] The present invention belongs to the technical field of battery connecting piece welding and punching, and in particular relates to an automatic welding and punching machine for battery connecting pieces. Background Art

[0002] In the field of battery production, battery connectors are crucial components in battery assemblies. Their production quality and efficiency directly affect the overall performance and production efficiency of the battery. With the vigorous development of the new energy industry, the demand for batteries is increasing, and higher requirements are also placed on the production of battery connectors. In the traditional battery connector production process, there is a lack of efficient and convenient battery fixing devices when welding and stamping the battery. The existing fixing methods often require manual tedious adjustments and fixation, which not only consumes a lot of time and energy, but also has an unstable fixing effect, which can easily cause the battery to move during the welding and stamping process. In addition, the stamping and welding of the connector are two independent steps. The connector needs to be stamped and formed on the stamping equipment first, and then transferred to the welding equipment for welding, which greatly reduces production efficiency. In view of this, we propose an automatic welding and stamping machine for battery connectors. Summary of the Invention

[0034] Example 6: This embodiment provides a battery connector automatic welding punching machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The power assembly includes: Rotating groove 27, the rotating groove 27 is opened in the mounting plate 14, and a bevel gear 28 is rotatably installed in the rotating groove 27. One end of the bevel gear 28 passes through one side of the rotating groove 27 and is fixed to the rotating plate 15. The bottom of the bevel gear 28 is meshed with a bevel gear 29 installed in the rotating groove 27. The bottom of the mounting plate 14 is fixedly installed with a third motor 30. The output end of the third motor 30 passes through the bottom of the mounting plate 14 and is coaxially connected to the bevel gear 2 29.

[0035] Among them, personnel can start the third motor 30, and the output shaft of the third motor 30 will drive the bevel gear 2 29 to rotate. Under the action of meshing, the rotation of the bevel gear 2 29 will drive the bevel gear 1 28 to rotate, and the rotation of the bevel gear 1 28 will drive the rotating plate 15 to rotate until the rotating plate 15 rotates 180°.

[0037] Here, it is ensured that the second bevel gear 29 can rotate normally in the rotation groove 27 , and that the output shaft of the third motor 30 can rotate normally in the mounting plate 14 .

[0038] Example 8: This embodiment provides a battery connector automatic welding punching machine. In addition to the technical solutions of the above embodiments, it also has the following technical features. The fixing assembly includes: Slot 18, slot 18 is opened at the bottom of the rotating plate 15, the top of the punch head 17 and the insert block 19 is fixedly installed in the slot 18, a groove 22 is opened in the rotating plate 15 and above the slot 18, a limit block 23 is slidably installed in the groove 22, the bottom end of the limit block 23 passes through the bottom of the groove 22 and extends into the slot 18, a plurality of limit rods 24 are fixedly installed on the top of the groove 22, a spring 25 is sleeved on the limit rod 24, and one side of the limit block 23 passes through the groove 22 and is fixedly installed with a pulling plate 26.

[0039] Among them, when it is necessary to stamp connecting pieces of different shapes, personnel can move the pulling plate 26 upward. The upward movement of the pulling plate 26 will drive the limit block 23 to move upward. The upward movement of the limit block 23 will squeeze the springs 25 to shrink until the bottom end of the limit block 23 moves out from one side of the plug block 19. At this time, the limit block 23 can release the limit of the plug block 19, and the personnel can use the punching head 17 to pull the plug block 19 out of the slot 18. After replacing the punching head 17, after the replacement is completed, release the pulling plate 26. Under the action of the rebound force of the springs 25, the springs 25 will squeeze the limit block 23 to move downward until the bottom end of the limit block 23 is against one side of the plug block 19, thereby limiting the plug block 19, ensuring that it is convenient for personnel to replace punching heads 17 of different shapes, and the replacement method is simple, fast and easy to operate.

[0040] The fixing assembly, through the clever cooperation between the insert block 19 and the limit block 23, not only realizes the quick replacement function, but also plays the following unexpected functions: 1. Vibration self-tightening function: The vibration generated during the stamping process causes the limit block 23 to produce a slight reciprocating motion under the action of the spring 1 25, which in turn tightens the contact surface between the insert block 19 and the slot 18, thus avoiding the problem of loosening of traditional threaded connections; 2. Overload protection: When the punching force increases abnormally, the spring 125 can be elastically deformed to absorb the impact and prevent the punch head 17 from being hard damaged; 3. Automatic centering correction: The tapered guide surface of the insert 19 cooperates with the slot 18 to automatically correct the position deviation of ±0.5mm during the insertion process, ensuring the installation accuracy of the punch head 17. These additional functions give this simple structure the triple advantages of anti-loosening, protection and self-calibration, greatly improving the reliability of the equipment.

[0041] Example 9: This embodiment provides an automatic welding punching machine for battery connectors. In addition to the technical solutions of the above-mentioned embodiments, it also has the following technical features: the bottom end of the limit block 23 is snap-fitted with the insert block 19, the insert block 19 is plug-fitted with the slot 18, and the two ends of the spring 25 are tightly welded to the limit block 23 and the top of the groove 22, respectively.

[0042] Among them, it is ensured that the limiting block 23 can fix the inserting block 19, ensure that the inserting block 19 can be inserted into the slot 18, and ensure the structural stability of the spring 1 25.

[0043] Furthermore, the bottom of the stopper 23 is machined with unidirectionally inclined wedge-shaped teeth (angled at 30° to 45°), which engage with the corresponding matching groove 22 at the top of the insert 19, forming a self-locking structure similar to a ratchet. When the insert 19 is inserted, the inclined surface of the teeth guides the stopper 23 upward, compressing spring 1 25. Once in position, spring 1 25 pushes the vertical surface of the teeth into a rigid engagement with groove 22, achieving mechanical self-locking. To replace the punch, the stopper 23 must be manually pulled up to disengage it. This dual locking design (spring pressure + mechanical engagement) effectively prevents the punch head from loosening due to high-frequency vibration, while also maintaining the ability to quickly replace the punch head.

[0044] Secondly, spring 1 (25) utilizes a variable stiffness spring, with a soft initial section (for ease of insertion and removal) and a hard section (to ensure locking force). This results in low stiffness in the initial section (for small deformations) and high stiffness in the latter section (for large deformations). This serves the purpose of compressing the spring with minimal operating force (less than 10N) during insertion and removal of the punch head (17), allowing the stopper (23) to be easily lifted. Once fully engaged, the hard section provides a locking force of up to 100N, ensuring rigid engagement between the wedge-shaped teeth and the groove (22). This nonlinear elastic characteristic maintains the convenience of manual operation while offsetting vibration and shock through high stiffness at the end. Tests have shown that locking reliability is many times greater than that of ordinary springs.

[0045] Example 10: This embodiment provides a battery connector automatic welding punching machine. In addition to the technical solutions of the above embodiments, it also has the following technical features: The revolving door 31 is rotatably installed on one side of the working chamber 2. An observation slot 32 is provided on the revolving door 31, and an observation plate 33 is fixedly installed in the observation slot 32. A handle 34 is fixedly installed on one side of the revolving door 31. A through slot 35 is provided in the working box 1, and a spring block 36 is slidably installed in the through slot 35. A limiting hole 37 is provided on the revolving door 31 and located on one side of the through slot 35. One end of the spring block 36 passes through one side of the through slot 35 and extends into the limiting hole 37. The other end of the spring block 36 is located in the through slot 35 and is fixedly installed with a pull rod 38. One end of the pull rod 38 passes through the other side of the through slot 35 and is fixedly installed with a pull ring 39. The other end of the spring block 36 is fixedly installed with two springs 40 fixed to the inner wall of the through slot 35.

[0046] Among them, during the welding and stamping process, the revolving door 31 can be closed, and the revolving door 31 will squeeze the spring block 36 to move, and the movement of the spring block 36 will squeeze the two springs 2 40 to shrink. When the revolving door 31 is completely closed, under the action of the rebound force of the two springs 2 40, the two springs 2 40 will squeeze the spring block 36 to move until one end of the spring block 36 is inserted into the limiting hole 37, thereby limiting the revolving door 31. At this time, the revolving door 31 and the observation plate 33 can protect personnel to prevent flying debris from welding and stamping from scratching people. At the same time, personnel can observe the working conditions in the working chamber 2 through the observation plate 33.

[0047] The structure of the revolving door 31 is designed with a linkage of a two-way spring 40 and a spring block 36. In addition to achieving basic protection functions, it can also play other roles, such as 1. Intelligent safety interlock: when the spring block 36 is not completely inserted into the limit hole 37, the micro switch is triggered to cut off the power of the device to prevent the door from being started without being closed; 2. Vibration adaptive locking: Spring 2 40 adopts an asymmetric stiffness design (horizontal stiffness > vertical stiffness), which can suppress the lateral shaking of the spring block 36 when the equipment vibrates at high frequencies, avoiding mis-locking; 3. Airflow Guide Seal: The wedge-shaped mating surface between spring block 36 and stop hole 37 guides the internal cooling airflow to form a vortex barrier, reducing the escape of welding fumes through the door gap and minimizing fume leakage. These multiple hidden functions combine to provide a simple mechanical door structure with the combined benefits of safety protection, anti-vibration locking, and environmental isolation. When spring block 36 is inserted into stop hole 37, the two inclined surfaces form a tapered airflow channel (wider inlet than narrower outlet). This channel accelerates the internal cooling airflow, creating a localized low-pressure zone due to the Bernoulli effect. Simultaneously, the asymmetric structure of the inclined surfaces forces the airflow to be deflected tangentially, forming a rotating vortex. This vortex has a dual function: dynamic sealing: the high-speed rotating airflow forms an "air curtain" at the door gap, centrifugal force flinging smoke particles toward the inner wall of the chamber; and pressure isolation: the low-pressure zone at the center of the vortex actively blocks external air infiltration. Field tests have shown that this structure reduces the escape rate of smoke particles without requiring additional energy, cleverly utilizing the equipment's existing cooling airflow to achieve a self-cleaning seal.

[0048] The working principle is as follows: when in use, a person can first pull the pull ring 39, which will drive the pull rod 38 to move. The movement of the pull rod 38 will drive the spring block 36 to move. The movement of the spring block 36 will squeeze the two springs 2 40 to shrink until one end of the spring block 36 moves out of the limit hole 37. At this time, the spring block 36 can release the limit of the revolving door 31, and the person can open the revolving door 31. Then the person can place the battery to be removed between the two clamping plates 5, and then start the first motor 8. The output shaft of the first motor 8 will drive the bidirectional threaded rod 7 to rotate. Under the action of the thread, the rotation of the bidirectional threaded rod 7 will drive the two sliding blocks 4 to move closer to each other. The two sliding blocks 4 move closer to each other and drive the two clamping plates 5 to move closer to each other. The two clamping plates 5 move closer to each other to clamp and fix the battery. At the same time, under the buffering action of the two rubber pads 6, the two clamping plates 5 can be prevented from damaging the battery, ensuring that it is convenient for personnel to fix the battery and ensuring that the battery will not move during welding and stamping. Afterwards, the personnel can start the second motor 21, and the output shaft of the second motor 21 will drive the threaded rod 20 to rotate. Under the action of the thread, the rotation of the threaded rod 20 will drive the moving block 10 to move, and the movement of the moving block 10 will drive the electric slide 11 to move. The movement of the electric slide 11 will drive the hydraulic cylinder 13 to move back and forth through the electric slider 12. At the same time, the personnel can start the electric slide 11, and the electric slide 11 will drive the electric slider 12 to move left and right, and the electric slider 12 will drive the hydraulic cylinder 13 to move left and right, thereby adjusting the front and back, left and right movements of the hydraulic cylinder 13 to ensure that welding and stamping can be performed on different positions of the battery, and then start the hydraulic cylinder 13, and the output shaft of the hydraulic cylinder 13 will drive the mounting plate 14 to move downward, and the mounting plate 14 moves downward The movement will drive the rotating plate 15 to move downward, and the downward movement of the rotating plate 15 will drive the punching head 17 to move downward. The downward movement of the punching head 17 can punch the connecting piece, and the connecting piece can be punched into a suitable shape. Then the personnel can start the third motor 30, and the output shaft of the third motor 30 will drive the bevel gear 29 to rotate. Under the action of meshing, the rotation of the bevel gear 29 will drive the bevel gear 1 28 to rotate, and the rotation of the bevel gear 1 28 will drive the rotating plate 15 to rotate until the rotating plate 15 rotates 180°. At this time, the connecting piece can be welded by the welding head 16 to ensure that the connecting piece can be automatically welded after the stamping is completed, thereby reducing the stamping and welding steps and eliminating the need for separate stamping and welding, which greatly saves working time. When it is necessary to punch connecting pieces of different shapes, personnel can move the pulling plate 26 upward. The upward movement of the pulling plate 26 will drive the limit block 23 to move upward. The upward movement of the limit block 23 will squeeze the springs 25 to shrink until the bottom end of the limit block 23 moves out from one side of the plug block 19. At this time, the limit block 23 can release the limit of the plug block 19, and the personnel can use the punching head 17 to pull the plug block 19 out of the slot 18. After replacing the punching head 17, after the replacement is completed, release the pulling plate 26. Under the action of the rebound force of the springs 25, the springs 25 will squeeze the limit block 23 to move downward until the bottom end of the limit block 23 is against one side of the plug block 19, thereby limiting the plug block 19, ensuring that it is convenient for personnel to replace punching heads 17 of different shapes, and the replacement method is simple, fast and easy to operate.
