[0030] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0031] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0032] In addition, in the present invention, the descriptions of "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0033] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0034] Reference Figure 1 , Figure 1 It is a schematic diagram of the structure of the welding equipment in this embodiment. The welding equipment in this embodiment includes an incoming material device 1, a pairing feeding device 2, a conveying device 3 and a welding device 4. The pairing feeding device 2 and the welding device 4 are respectively arranged on the conveying path of the conveying device 3, and the incoming material device 1 is adjacent to the pairing feeding device 2. The incoming material device 1 is used for the incoming material of the product, the pairing feeding device 2 receives the incoming product, and pairs at least two qualified products to transfer to the conveying device 3, the conveying device 3 conveys at least two qualified products through the welding device 4, and the welding device 4 welds at least two qualified products. Through the coordinated setting of the incoming material device 1, the pairing feeding device 2, the conveying device 3 and the welding device 4, a plurality of qualified products are first paired and then synchronously loaded, thereby ensuring the output of qualified products welded by the welding device 4, avoiding the waste of welding resources, and reducing enterprise costs.

[0035] Re-reference Figure 1 Furthermore, the welding device in this embodiment further includes a cleaning device 5. The cleaning device 5 is arranged on the conveying path of the conveying device 3. The cleaning device 5 is used for cleaning the product before welding. The cleaning device 5 is used to clean the product before welding to obtain a better welding effect. The product in this embodiment is a battery after liquid injection, and the product cleaning is to clean the liquid injection port of the battery.

[0036] Re-reference Figure 1Furthermore, the welding device in this embodiment also includes a sealing nail feeding device 6. The sealing nail feeding device 6 is arranged on the conveying path of the conveying device 3 and is adjacent to the welding device 4. The sealing nail feeding device 6 is used to feed the sealing nails to the product before welding. The welding in this embodiment is to weld the sealing nails to the liquid injection port of the battery to weld and seal the electrolyte of the battery, so the sealing nails need to be fed to the liquid injection port of the battery before welding.

[0037] Re-reference Figure 1 Furthermore, the welding device 4 of this embodiment includes a pre-welding mechanism 41 and a full-welding mechanism 42. The pre-welding mechanism 41 and the full-welding mechanism 42 are sequentially arranged on the conveying path of the conveying device 3. The sealing pins at the battery filling port are pre-welded and fully welded by the pre-welding mechanism 41 and the full-welding mechanism 42 respectively to ensure the welding effect.

[0038] Re-reference Figure 1 Furthermore, the welding device in this embodiment further includes a detection device 7. The detection device 7 is arranged on the conveying path of the conveying device 3 and is adjacent to the welding device 4. The detection device 7 is used to detect the product after welding. The welding part between the battery filling port and the sealing nail is detected by the detection device 7 to ensure the welding quality.

[0039] Referring again to 1, further, the welding equipment in this embodiment also includes a material removal device 8. The material removal device 8 is arranged on one side of the conveying device 3, and is used to transfer the product after welding. The transfer device is provided so that the welding equipment can be continuous with other process equipment. Preferably, the material removal device 8 includes a spacing adjustment mechanism 81 and a material removal mechanism 82. The spacing adjustment mechanism 81 is adjacent to the starting end of the material removal mechanism 82, and the spacing adjustment mechanism 81 is used to adjust the spacing between products, and the material removal mechanism 82 transfers the products after the spacing is adjusted. It can be understood that the spacing between the multiple products required by the welding equipment in this embodiment is different from the spacing between the multiple products required to be loaded by other process equipment. Therefore, before the multiple products after welding are synchronously transferred, it is necessary to adjust the spacing between adjacent products so as to adapt to the product spacing required by the next process equipment of the welding equipment, thereby making the entire process more continuous.

[0040] Continue to refer to Figure 1 and Figure 2 , Figure 2 In this embodiment Figure 1An enlarged view of part A. Furthermore, the incoming material device 1 includes an incoming material mechanism 11 and an incoming material detection mechanism 12. The incoming material detection mechanism 12 is arranged on the incoming material mechanism 11, and its detection end is facing the incoming material conveying line of the incoming material mechanism 11. The end of the incoming material mechanism 11 is adjacent to the matching feeding device 2, and the end of the incoming material mechanism 11 is provided with an incoming material position for the matching feeding device 2 to perform matching feeding. Multiple products to be welded are placed side by side at the starting end of the incoming material mechanism 11, and then conveyed to the end of itself by the incoming material mechanism 11 and stay, waiting for matching feeding by the incoming material detection mechanism 12, and will pass through the incoming material detection mechanism 12 during the conveying process, and the incoming material detection mechanism 12 will detect the passing products. The incoming material mechanism 11 in this embodiment can adopt the multi-station conveying line mechanism in the prior art, which can synchronously convey multiple products side by side. In this embodiment, four products are conveyed side by side at one time. The incoming material inspection mechanism 12 can be a barcode scanning gun, which scans the product for inspection. If the scanned code is qualified, it is a qualified product, otherwise it is a failed product; or a CCD inspection system, which performs appearance inspection on the product. If the appearance is qualified, it is a qualified product, otherwise it is a failed product; or other inspection mechanisms in the prior art, which are not limited here. The batching and feeding device 2 excludes unqualified products according to the results of the product inspection, and pairs a plurality of qualified products side by side, and then feeds them to the conveying device 3.

[0041] Re-reference Figure 2 , further, the pairing feeding device 2 includes a pairing material transfer mechanism 21 and a first temporary storage mechanism 22. The pairing material transfer mechanism 21 is arranged on the conveying path of the conveying device 3, and the first temporary storage mechanism 22 and the incoming material device 1 are respectively arranged on the material transfer path of the pairing material transfer mechanism 21. The first temporary storage mechanism 22 is used for the temporary storage of qualified products. Among them, the pairing material transfer mechanism 21 and the first temporary storage mechanism 22 are respectively located between the incoming material device 1 and the conveying device 3, and the first temporary storage mechanism 22 is located on one side of the pairing material transfer mechanism 21. The pairing material transfer mechanism 21 can synchronously transfer multiple qualified products from the end incoming material position of the incoming material mechanism 11 to the conveying device 3, or transfer a single or multiple qualified products from the end incoming material position of the material mechanism 11 to the first temporary storage mechanism 22, or transfer a single or multiple qualified products temporarily stored in the first temporary storage mechanism 22 to the end incoming material position of the incoming material mechanism 11.

[0042] Preferably, the paired loading device 2 also includes a defective product removal mechanism 23. The defective product removal mechanism 23 is arranged on the material transfer path of the paired material transfer mechanism 21, and is used to remove defective products. Among them, the defective product removal mechanism 23 is located on the side of the paired material transfer mechanism 21 away from the conveying device 3. Preferably, the starting end of the defective product removal mechanism 23 is close to the end of the incoming material mechanism 11. The paired material transfer mechanism 21 can transfer a single or multiple defective products at the incoming material position at the end of the incoming material mechanism 11 to the starting end of the defective product removal mechanism 23, or transfer the welding defective products detected by the detection device 7 to the starting end of the defective product removal mechanism 23.

[0043] Preferably, the pairing feeding device 2 also includes a second temporary storage mechanism 24. The second temporary storage mechanism 24 is arranged on the material transfer path of the pairing material transfer mechanism 21, and is used for the temporary storage of qualified welding products. Among them, the second temporary storage mechanism 24 is located between the incoming material device 1 and the conveying device 3, and is located on one side of the pairing material transfer mechanism 21. Preferably, the second temporary storage mechanism 24 is adjacent to the first temporary storage mechanism 22. The second temporary storage mechanism 24 in this embodiment is used for the temporary storage of qualified welding products detected by the detection device 7. The pairing material transfer mechanism 21 can transfer a single or multiple qualified welding products detected by the detection device 7 from the conveying device 3 to the second temporary storage mechanism 24, and can continue to transfer a single or multiple qualified welding products from the second temporary storage mechanism 24 to the spacing adjustment mechanism 81, or the pairing material transfer mechanism 21 can also transfer multiple qualified welding products detected by the detection device 7 from the conveying device 3 to the spacing adjustment mechanism 81.

[0044] Specifically, the paired material transfer mechanism 21 includes a paired transfer component 211 and a paired clamping component 212. The paired clamping component 212 is arranged at the end of the paired transfer component 211. The paired transfer component 211 is used to transfer the paired clamping component 212 to the end of the incoming material mechanism 11, the first temporary storage mechanism 22, the beginning of the unqualified product removal mechanism 23, the second temporary storage mechanism 24 and the conveying device 3. The paired clamping component 212 is used to clamp or release a single or multiple products, thereby realizing the transfer of qualified products or unqualified products. The paired transfer component 211 in this embodiment can adopt a four-axis or six-axis robot. The paired clamping component 212 includes a plurality of paired clamping members 2121 arranged side by side, each of which can grasp or release the product individually, and the plurality of paired clamping members 2121 arranged side by side can realize the overall grasping and releasing action of a plurality of products arranged side by side, or the grasping and releasing action of a single product. The number of the matching clamping members 2121 in this embodiment is four, and each matching clamping member 2121 can adopt the cooperation of the cylinder and the clamping claw, which will not be repeated here. The first temporary storage mechanism 22 includes a temporary storage bracket 221 and a temporary storage plate 222. The temporary storage plate 222 is arranged at the upper end of the temporary storage bracket 221. The surface of the temporary storage plate 222 is provided with a plurality of temporary storage positions 2221 arranged side by side. The structure and shape of the temporary storage position 2221 are adapted to the structure and shape of the product, and it is used for the temporary storage of the product. The temporary storage position 2221 in this embodiment is a groove provided on the temporary storage plate 222, and the number thereof is four. The four temporary storage positions 2221 are arranged in sequence along the length direction of the temporary storage plate 222. Preferably, two adjacent temporary storage positions 222 are connected. Preferably, both ends of the groove of each temporary storage position 222 have a "V"-shaped structure, which is convenient for the temporary storage and positioning of the product, and can also be adapted to products of different specifications and sizes to increase the adaptability of the temporary storage position 222. The defective product removal mechanism 23 can adopt a mechanism consistent with the incoming material mechanism 11, and the structure and actuation principle of the second temporary storage mechanism 24 are consistent with those of the first temporary storage mechanism 22, which will not be repeated here.

[0045] There are two ways of pairing loading process in this embodiment: in the first pairing loading process, the first four batteries are transferred by the incoming material mechanism 11 to the incoming material position at its own end. If the first four batteries detected by the incoming material detection mechanism 12 are all qualified batteries, the pairing material transfer mechanism 21 directly transfers the four qualified batteries to the first temporary storage mechanism 22; if there are unqualified batteries among the first four batteries detected by the incoming material detection mechanism 12, the pairing material transfer mechanism 21 transfers the qualified batteries among the four to the first temporary storage mechanism 22, and transfers the unqualified batteries among the four to the unqualified product removal mechanism 23. Afterwards, the incoming material mechanism 11 continues to transfer four batteries to the incoming material position at its own end. If the subsequent four batteries are all qualified batteries, the paired material transfer mechanism 21 will synchronously transfer the four qualified batteries to the conveying device 3; if there are unqualified batteries among the subsequent four batteries, the paired material transfer mechanism 21 will transfer the unqualified batteries to the unqualified product removal mechanism 23. At this time, the qualified batteries at the incoming material position of the incoming material mechanism 11 are missing, and then the paired material transfer mechanism 21 transfers the corresponding qualified batteries from the first temporary storage mechanism 22 to the incoming material position of the incoming material mechanism 11, so that the batteries at the incoming material position of the incoming material mechanism 11 are supplemented with four qualified batteries, and then the paired material transfer mechanism 21 transfers four qualified batteries to the conveying device 3. If the qualified batteries temporarily stored in the first temporary storage mechanism 22 are not enough to make up for the missing qualified batteries at the incoming material position of the incoming material mechanism 11, the paired material transfer mechanism 21 will transfer the qualified batteries at the incoming material position of the incoming material mechanism 11 to the first temporary storage mechanism 22 for temporary storage, waiting for the next replenishment and material collection. In this way, the four batteries synchronously transferred to the conveying device 3 by the paired material transfer mechanism 21 are all qualified batteries. In the second paired material loading process, the first four batteries are transferred to the incoming material position at the end of the material mechanism 11. If the first four batteries detected by the incoming material detection mechanism 12 are all qualified batteries, the paired material transfer mechanism 21 directly transfers the four qualified batteries to the conveying device 3. The material mechanism 11 continues to transfer. When unqualified products appear in the products subsequently transferred by the incoming material mechanism 11, the paired material transfer mechanism 21 transfers the four qualified batteries to the first temporary storage mechanism 22, and transfers the four unqualified batteries to the unqualified product removal mechanism 23. If there are unqualified batteries in the first four batteries detected by the incoming material detection mechanism 12, the paired material transfer mechanism 21 transfers the four qualified batteries to the first temporary storage mechanism 22, and transfers the four unqualified batteries to the unqualified product removal mechanism 23. The rest of the subsequent completion process is consistent with the first paired material loading process, and will not be repeated here.

[0046] Continue to refer to Figure 3 , Figure 3It is a schematic diagram of the structure of the conveying device in this embodiment. Furthermore, the conveying device 3 includes a clamp 31 and a transmission component 32. The clamp 31 is arranged on the transmission component 32, and the transmission component 32 is used for the transmission of the clamp 31.

The transmission component 32 in this embodiment is a turntable mechanism. There are six clamps 31, which are respectively arranged on the surface of the transmission component 32 and arranged in sequence along the periphery of the transmission component 32. The transmission component 32 rotates, driving the clamps 31 to rotate, so that the clamps 31 pass through the above six devices or mechanisms in sequence and pause. The above six devices or mechanisms perform loading and unloading, cleaning, sealing nail loading, pre-welding, full welding and welding inspection on the qualified products clamped and positioned by the clamps 31 in sequence. The clamping and positioning of the qualified products by the clamps 31 ensures the accuracy of the process operation of the above six devices and the smoothness of the product flow operation.

The driving end of the clamping and positioning driving portion 314 is connected to the clamping and positioning portion 313, and the clamping and positioning driving portion 314 drives the clamping and positioning portion 313 to clamp and position the product carried by the bearing portion 311 based on the positioning reference portion 312. Through the cooperation of the bearing portion 311, the positioning reference portion 312, the clamping and positioning portion 313, and the clamping and positioning driving portion 314, the product can be accurately positioned at a determined position when fixed, thereby ensuring the accuracy of the position of the product during the transmission and stop, and facilitating the other six devices or mechanisms to accurately operate the product.

Preferably, the fixture 31 also includes a lifting portion 316. The lifting portion 316 is connected to the load-bearing portion 311, and is used for lifting and lowering the load-bearing portion 311. The setting of the lifting portion 316 facilitates lifting the load-bearing portion 311, and then lifting the product to a desired position, so that other devices can operate on the product, for example, lifting the product at the cleaning station, so that the cleaning device 5 can position, flatten and laser clean the upper end surface of the product, for example, lifting the product at the pre-welding and full-welding stations, so as to facilitate the laser welding operation of the pre-welding mechanism 41 and the full-welding mechanism 42.

[0049] Preferably, the fixture 31 further includes a mounting plate 317. The mounting plate 317 in this embodiment is a rectangular plate. Preferably, a notch 3171 is provided at one end of the mounting plate 317. The bearing portion 311 is laid on the mounting plate 317.

The bearing adjustment portion 315 in this embodiment is a block, which is fixed to the upper surface of the bearing portion 311 by screws. The product is carried on the bearing adjustment portion 315. By replacing the bearing adjustment portion 315 of different sizes, for example, the bearing adjustment portion 315 of different heights, widths and lengths, it is possible to carry products of different specifications and sizes correspondingly, so as to increase the applicability of the carried product. The positioning reference portion 312 is provided on the bearing portion 311 and is located on the side of the bearing adjustment portion 315 away from the notch 3171.

Preferably, the position of the positioning reference position 3121 near the bottom of its own groove is a rectangular groove, and the position near its own notch is an open groove shape similar to the "eight" shape, so that the product can be smoothly clamped in the positioning reference position 3121.

The clamping and positioning portion 313 is opposite to the positioning reference portion 312. The clamping and positioning portion 313 is block-shaped, and its height is greater than the bearing adjustment portion 315. The clamping and positioning portion 313 in this embodiment forms a sliding connection relationship with the bearing portion 311 through the cooperation of the slide rail and the slider, so that the clamping and positioning portion 313 can move linearly in the direction of the positioning reference portion 312, thereby forming a clamping cooperation with the positioning reference portion 312 to clamp the product carried by the bearing adjustment portion 315. Preferably, a clamping position 3131 is provided at one end of the clamping and positioning portion 313 opposite to the positioning reference position 3121, and the clamping position 3131 is adapted to the shape of the product to facilitate the adaptive clamping of the product. The structure and actuation principle of the clamping position 3131 in this embodiment are compatible with the structure and actuation principle of the positioning reference position 3121, and will not be repeated here.In this way, through the cooperation of the positioning reference position 3121 and the clamping position 3131, the product can be clamped while being accurately positioned and limited, ensuring that the position of the product carried on the carrying adjustment part 315 is fixed and stable, and will not be misplaced due to the transportation and stop of the product, thereby facilitating other devices to perform accurate operations on the product.

When the stretching plate 31413 is moved in a direction away from the positioning reference portion 312, the stretching guide rod 31412 slides in the stretching support plate 31411 and drives the clamping positioning portion 313 away from the positioning reference portion 312, and the clamping reset member 3142 is compressed under the action of the clamping positioning portion 313 and the stretching support plate 31411; then, the product is carried on the load-bearing adjustment portion 315; then, the pulling force on the stretching plate 31413 disappears, and the clamping reset member 3142 acts on the clamping positioning portion 313 to move toward the positioning reference portion 312, so that the clamping positioning portion 313 and the positioning reference portion 312 cooperate to position and clamp the product. Among them, the stretching guide rod 31412 can also serve as a guide when the clamping positioning portion 313 moves. The clamping reset member 3142 in this embodiment can be a spring. Preferably, the number of the stretching guide rods 31412 and the clamping reset parts 3142 are four, one end of the four stretching guide rods 31412 is respectively connected to the four corners of the clamping positioning part 313, the other ends of the four stretching guide rods 31412 pass through the four corners of the stretching support plate 31411, and the four clamping reset parts 3142 are respectively sleeved on the stretching guide rods 31412. In this way, the four stretching guide rods 31412 can increase the stability of the movement of the clamping positioning part 313 and the accuracy of the displacement direction, and the four clamping reset parts 3142 can increase the reset clamping force of the clamping positioning part 313, so that the finished product can be stably loaded and fixed. Preferably, the positioning reference part 312, the clamping positioning part 313 and the load-bearing adjustment part 315 can be made of corrosion-resistant materials to facilitate the load-bearing clamping and positioning of corrosive products, for example, the battery filling port will retain electrolyte.

[0051] Re-reference Figure 5Furthermore, the lifting part 316 includes a lifting member 3161, a lifting reset member 3162 and a lifting guide member 3163. One end of the lifting reset member 3162 and the lifting guide member 3163 are respectively connected to the lifting member 3161, the other end of the lifting reset member 3162 is connected to the mounting plate 317, and the other end of the lifting guide member 3163 is connected to the bearing part 311. The lifting member 3161 is lifted and acts on the lifting guide member 3163, so that the lifting guide member 3163 lifts the bearing part 311, thereby lifting the product and compressing the lifting reset member 3162 at the same time. When the lifting state of the lifting member 3161 disappears, the lifting reset member 3162 acts in the reverse direction, driving the lifting guide member 3163 to act in the reverse direction on the bearing part 311 to restore the original position. Specifically, the lifting member 3161 is plate-shaped, which is located directly below the mounting plate 317 and parallel to the bearing part 311. One end of the lifting and restoring member 3162 is connected to the surface of the lifting member 3161 and is located in the middle of the lifting member 3161, and the other end thereof is connected to the lower surface of the mounting plate 317. The lifting and restoring member 3162 in this embodiment can be a spring. There are two lifting guide members 3163, and the lifting guide members 3163 are respectively located on the opposite sides of the lifting and restoring member 3162 and are respectively parallel to the lifting and restoring member 3162. Each lifting guide member 3163 includes a lifting guide rod 31631 and a lifting guide sleeve 31632. One end of the lifting guide rod 31631 is connected to the lifting member 3161, and the other end thereof passes through the mounting plate 317 and is connected to the bearing portion 311. The lifting guide rod 31631 is slidably connected to the mounting plate 317, and the lifting guide sleeve 31632 is arranged on the lower surface of the mounting plate 317 and sleeved outside the lifting guide rod 31631. In this way, when the lifting member 3161 is lifted, the lifting guide rod 31631 is driven to push the bearing part 311 to rise, thereby driving the product to rise. At the same time, the lifting reset member 3162 is compressed under the action of the lifting member 3161 and the mounting plate 317; and when the lifting state of the lifting member 3161 disappears, the lifting reset member 3162 pushes the lifting member 3161 in the opposite direction to restore the bearing part 311 to its original position. The lifting guide sleeve 31632 cooperates with the lifting guide rod 31631 to guide the lifting and lowering of the bearing part 311. The bearing part 311, the positioning reference part 312, the clamping and positioning part 313, the clamping and positioning driving part 314, the bearing adjustment part 315 and the lifting part 316 in this embodiment can be adaptively set to four, so as to facilitate synchronous or asynchronous bearing, clamping, positioning or lifting of four products. An installation position for the fixture 31 is reserved on the turntable of the transmission component 32, and the mounting plate 317 of the fixture 3131 is fixedly installed on the turntable of the transmission component 32. The lifting member 3161 of the fixture 3131 and the stretching plate 31413 of the fixture 3131 are respectively exposed on the lower surface of the turntable of the transmission component 32.

[0052] Re-reference Figure 3Furthermore, the conveying device 3 in this embodiment also includes a clamping assembly 33. The clamping assembly 33 is arranged on the conveying path of the transmission assembly 32, and is used to clamp the passing clamp 31. Specifically, the clamping assembly 33 is located below the transmission assembly 32, and acts on the stretching plate 31413 of the clamp 31 passing above, thereby realizing the clamping and positioning portion 313 of the clamp 31 to be clamped. Preferably, the conveying device 3 also includes a lifting assembly 34. The lifting assembly 34 is arranged on the conveying path of the transmission assembly 32, and is used to lift the passing clamp 31. The lifting assembly 34 is correspondingly arranged below the turntable of the transmission assembly 32 where the cleaning device 5, the pre-welding mechanism 41 and the full welding mechanism 42 are located, so that the lifting assembly 34 acts on the lifting member 3161, lifts the lifting member 3161 and then lifts the product to the corresponding working position.

[0053] Continue to refer to Figure 6 and Figure 7 , Figure 6 Schematic diagram of the structure of the clamping assembly in this embodiment. Figure 7It is a structural schematic diagram of the lifting assembly in this embodiment. Furthermore, the clamp opening assembly 33 includes a clamp opening drive member 331 and a clamp opening member 332.

Specifically, the clamp opening assembly 33 also includes a clamp opening support frame 333 and a clamp opening slide 334. The clamp opening slide 334 is slidably connected to the clamp opening support frame 333. The clamp opening drive member 331 includes a first clamp opening driver 3311 and a second clamp opening driver 3312. The output end of the first clamp opening driver 3311 is connected to the clamp opening slide 334, which drives the clamp opening slide 334 to move linearly in a direction perpendicular to the turntable of the transmission assembly 32. The first clamp opening driver 3311 in this embodiment is a cylinder. The second clamping driver 3312 is disposed at the upper end of the clamping slide 334, and its output end is connected to the clamping member 332. The second clamping driver 3312 drives the clamping member 332 to move linearly in a direction parallel to the turntable of the transmission component 32. In this embodiment, the second clamping driver 3312 may be a cylinder. The linear movement of the clamping slide 334 drives the second clamping driver 3312 and the clamping member 332 to move linearly in a direction perpendicular to the turntable of the transmission component 32. In this way, the linear movement of the clamping member 332 parallel to and perpendicular to the turntable of the transmission component 32 is achieved through the cooperation of the first clamping driver 3311 and the second clamping driver 3312. The clamping member 332 is enabled to rise and move to the side of the stretching plate 31413 close to the clamping and positioning portion 313, and then move to the side away from the clamping and positioning portion 313, so that the stretching plate 31413 drives the clamping and positioning portion 313 to open. After the product is loaded, the clamping member 332 is reset and retracted, and the product is clamped and positioned. When the product needs to be removed, the above-mentioned clamping action can be repeated. The clamping member 332 in this embodiment is plate-shaped, and preferably, the longitudinal section of the clamping member 332 is "L"-shaped. The product in this embodiment requires an unclamping fixture 31 when loading and unloading, so an unclamping assembly 33 is provided below the transmission assembly 32 of the corresponding matching loading device 2. The lifting assembly 34 includes a lifting drive member 341 and a lifting member 342. The output end of the lifting drive member 341 is connected to the lifting member 342, which drives the lifting member 342 to lift the fixture 31. Specifically, the lifting assembly 34 also includes a lifting support frame 343. The lifting drive member 341 is arranged on the lifting support frame 343, and its output end is connected to the lifting member 342. The lifting drive member 341 drives the lifting member 342 to move linearly along the direction perpendicular to the turntable of the transmission assembly 32, so that the lifting member 342 abuts against the lifting member 3161 and continues to lift, thereby lifting the product. The lifting drive member 341 in this embodiment can be a cylinder, and the lifting member 342 is block-shaped. Preferably, the lifting assembly 34 can be set to four corresponding to the number of lifting plates 161, and the four lifting assemblies 34 are arranged in sequence at intervals, so that the four products can be lifted separately, so as to facilitate the operation of the separate products.The number of the lifting assemblies 34 in this embodiment is three, and the three lifting assemblies 34 are respectively arranged below the transmission assembly 32 corresponding to the locations of the cleaning device 5, the pre-welding mechanism 41 and the full welding mechanism 42.

[0054] Re-reference Figure 3 Furthermore, the conveying device 3 in this embodiment also includes a positioning component 35. The positioning component 35 is arranged on the conveying path of the transmission component 32, and is used to position the passing fixture 31. The fixture 31 in transmission is positioned by the positioning component 35 to determine whether the fixture 31 has reached a predetermined position, so that the transmission component 32 can accurately pause the fixture 31. In this embodiment, the positioning component 35 is located below the turntable of the transmission component 32, and includes a positioning support frame 351 and a positioning member 352. The positioning member 352 is arranged on the positioning support frame 351, and the positioning end of the positioning member 352 faces the turntable of the transmission component 32. When the positioning member 352 detects the arrival of the fixture 31, it transmits a signal to the transmission component 32, so that the transmission component 32 can perform pause control. The positioning member 352 in this embodiment can use a photoelectric sensor. Preferably, the positioning member 352 can be used to detect whether there is a product on the load-bearing adjustment part 315. Please refer to Figure 4 A detection port 3151 is reserved between the load-bearing adjustment portion 315 and the positioning reference position 3121. The detection light of the positioning member 352 can detect the product carried by the load-bearing adjustment portion 315 through the turntable of the transmission component 32, the mounting plate 317 and the reserved through-hole of the load-bearing portion 311, so as to detect the presence or absence of the product, so as to facilitate the operation of other devices. If the product is detected at the same time, it means that the fixture 31 is also rotated into place. Preferably, four positioning members 352 are arranged side by side and spaced apart on each positioning support frame 351 to detect the four products on the fixture 31 respectively. The number of positioning components 35 in this embodiment is six, and the six positioning components 35 are respectively arranged at the devices or mechanisms of the six workstations and are arranged below the transmission component 32, so as to realize the precise control and positioning of the six process positions of the fixture 31. The clamping assembly 33, the lifting assembly 34 and the positioning assembly 35 in this embodiment are respectively arranged outside the transmission assembly 32. The transmission assembly 32 is only provided with a clamp 31. The external clamping assembly 33, the lifting assembly 34 and the positioning assembly 35 cooperate with the clamp 31. This can simplify the structure of the transmission assembly 32 and reduce the cost of the enterprise.

[0055] Continue to refer to Figure 8 and Fig. 9 , Figure 8 is a schematic diagram of the structure of the cleaning device in this embodiment, Fig. 9: is a schematic diagram of the structure of the cleaning positioning assembly in this embodiment. Furthermore, the cleaning device 5 includes a cleaning positioning assembly 51, a cleaning assembly 52 and a cleaning drive assembly 53. The cleaning positioning assembly 51 is used to position the product, the cleaning end of the cleaning assembly 52 faces the cleaning positioning assembly 51, the driving end of the cleaning drive assembly 53 is connected to the cleaning assembly 52, the cleaning drive assembly 53 drives the cleaning end of the cleaning assembly 52 to approach the part to be cleaned of the product positioned by the cleaning positioning assembly 51, and the cleaning assembly 52 cleans the part to be cleaned of the product. Among them, the cleaning positioning assembly 51 includes a reference positioning member 511 and a cleaning port 512. The cleaning port 512 is opened in the reference positioning member 511. The conveying assembly 33 conveys the fixture 31 to the position where the cleaning device 5 is located. At this time, the lifting assembly 34 lifts the fixture 31, and then lifts the four batteries to abut against the reference positioning member 5111, so that the upper end surface of the battery is positioned with the reference positioning member 511 as the reference surface, and the liquid injection port to be cleaned of the battery is in the cleaning port 512. By setting the reference positioning member 511, the product is positioned with the reference positioning member 511 as a reference surface, so that the cleaning port 512 can position the part of the product to be cleaned, and then the cleaning drive component 53 can drive the cleaning component 52 to clean the part of the product to be cleaned at an accurate position and an accurate height, so that the cleaning end of the cleaning component 52 can clean the part of the product to be cleaned at an optimal position, thereby ensuring the cleaning effect and thus ensuring the welding effect of the subsequent process.

[0056] Continue to refer to Figures 9 to 11 , Fig.10 is another structural schematic diagram of the cleaning and positioning assembly in this embodiment, Fig.11 In this embodiment Fig.10The enlarged view of part B. The cleaning positioning assembly 51 also includes a cleaning positioning frame 510. The cleaning positioning frame 510 includes a cleaning positioning bracket 5101 and a positioning support plate 5102. The cleaning positioning frame 510 is located below the cleaning assembly 52, and the cleaning positioning bracket 5101 is perpendicular to the positioning support plate 5102. One end of the positioning support plate 5102 is arranged at the upper end of the cleaning positioning bracket 5101, and the other end of the positioning support plate 5102 extends in a direction away from the cleaning positioning bracket 5101, so that the other end of the positioning support plate 5102 is in a suspended state. A positioning notch 51021 is provided at the suspended end of the positioning support plate 5102, and the positioning notch 51021 in this embodiment is a "U"-shaped notch. The reference positioning member 511 is arranged at the suspended end of the positioning support plate 5102 and is fixed to the lower surface of the positioning support plate 5102. The reference positioning member 511 is directly opposite to the positioning notch 51021, so that the reference positioning member 511 covers the positioning notch 51021. The reference positioning member 511 in this embodiment is a rectangular plate. Preferably, the number of cleaning ports 512 is four, and the four cleaning ports 512 are arranged in sequence along the length direction of the reference positioning member 511. During cleaning, the battery abuts against the lower surface of the reference positioning member 511 in a direction perpendicular to the reference positioning member 511, so that the liquid injection port of the battery is directly inserted into the cleaning port 512, so that the reference positioning member 511 forms an upper positioning for the product, and then the cleaning drive component 53 drives the cleaning end of the cleaning component 52 to perform laser cleaning from the upper surface of the reference positioning member 511 corresponding to the cleaning port 512, so that not only can the cleaning position of the cleaning component 52 be ensured to be accurate, but also the distance between the cleaning end of the cleaning component 52 and the part to be cleaned of the product is determined, so that the cleaning end of the cleaning component can clean the part to be cleaned of the product at an optimal height distance, thereby ensuring the cleaning effect.

[0057] Preferably, the cleaning positioning assembly 51 also includes a cleaning cover 513. The cleaning cover 513 is inserted into the cleaning port 512. The part of the product to be cleaned is in the cleaning cover 513. The cleaning cover 513 in this embodiment is cylindrical. Preferably, the cleaning cover 513 can be made of copper, for example, a copper mouth and a copper cap. The cleaning cover 513 is in the cleaning port 512, so that a new cleaning port is formed in the hollow part of the cleaning cover 513, and the liquid injection port of the battery is inserted into the cleaning cover 513, and then laser cleaning is performed. In this way, the positioning accuracy of the part of the product to be cleaned is further increased by the setting of the cleaning cover 513, and at the same time, the laser cleaning can be limited to the cleaning cover 513, so as to avoid interference or even damage to other non-cleaning parts, and provide protection during cleaning.

[0058] Preferably, the cleaning positioning assembly 51 also includes a dust blowing member 514. The dust blowing member 514 is connected to the cleaning cover member 513, and is used for dust blowing and cleaning of the to-be-cleaned part of the product in the cleaning state. The dust blowing member 514 is used to blow dust during the laser cleaning process in the cleaning cover member 513, blow out cleaning debris, and ensure the cleaning quality. Preferably, the cleaning positioning assembly 51 also includes a dust suction member 515. The dust suction member 515 is connected to the cleaning cover member 513, and is used for dust blowing and cleaning of the to-be-cleaned part of the product in the cleaning state. The dust suction member 515 is used to suction dust during the laser cleaning process in the cleaning cover member 513, suck out cleaning debris, and ensure the cleaning quality. Under the joint cooperation of the dust blowing member 514 and the dust suction member 515, it is further avoided that cleaning debris stays in the cleaning cover member 513, and the cleaning debris in the cleaning cover member 513 can be removed in time, and the removal effect is effective. Specifically, the two ends of the cleaning cover 513 are exposed to the upper and lower surfaces of the reference positioning member 511, respectively, and the dust blowing member 514 and the dust collecting member 515 are connected to the two ends of the cleaning cover 513. Preferably, the extension lines of the dust blowing member 514 and the dust collecting member 515 are staggered to form an angle, which is an obtuse angle. The dust blowing member 514 in this embodiment is arranged on the lower surface of the reference positioning member 511, one end of which is connected to the lower end of the cleaning cover 513, and the other end of which is connected to the dust blowing device outside through the pipeline, such as a hair dryer. The dust collecting member 515 is cylindrical, one end of which is connected to the upper end of the cleaning cover 513, and the other end of which is connected to the dust collecting device outside through the pipeline, such as a vacuum cleaner. Preferably, the dust collecting member 515 and the cleaning cover 513 can be integrally formed. In this way, the dust blowing member 514 blows air and the dust collecting member 515 sucks air synchronously, so as to timely and efficiently remove the cleaning debris in the cleaning cover 513. The obtuse-angle structure of the dust blowing member 514 and the dust collecting member 515 allows the dust blowing airflow of the dust blowing member 514 and the dust collecting airflow of the dust collecting member 515 to jointly form a dust exhausting airflow that can fully fill the entire internal space of the cleaning cover member 513, thereby ensuring the completeness of dust exhausting.

[0059] Preferably, the cleaning positioning assembly 51 also includes an in-place detection member 516. The in-place detection member 516 is used to detect whether the product is located at the reference positioning member 511. The in-place detection member 516 in this embodiment is arranged on the positioning support plate 5102, and its in-place detection end faces the reference positioning member 511 and extends to the lower surface of the reference positioning member 511. Specifically, the reference positioning member 511 is provided with a through hole corresponding to the position of the in-place detection member 516, and the in-place detection member 516 is fixed to the upper surface of the positioning support plate 5102 through a connecting plate, and the in-place detection member 516 is directly opposite to the through hole, and the detection end of the in-place detection member 516 passes through the through hole and along to the lower surface of the reference positioning member 511. In this embodiment, the in-place detection member 516 can adopt a proximity switch. In this way, when the product is abutted against the lower surface of the reference positioning member 511, the in-place detection member 516 will obtain the in-place signal of the product, so that the cleaning drive assembly 53 drives and controls the cleaning assembly 52 to perform cleaning. Preferably, the cleaning positioning assembly 51 also includes an in-place detection member 517. The in-place detection member 517 is used to detect whether the product is located at the reference positioning member 511. The in-place detection member 517 is arranged at the reference positioning member 511, and the detection end of the in-place detection member 517 extends toward the bottom of the reference positioning member 511 and fits with the side of the product, so as to facilitate the detection of whether the product is in place. Specifically, the in-place detection member 517 is fixed to the side wall of the reference positioning member 511 through a connecting plate, so that the in-place detection member 517 is suspended below the reference positioning member 511, and the detection end of the in-place detection member 517 fits with the product, so that when the product leaves and the in-place detection member 517 cannot detect the product, it indicates that the product has been completely separated, which is convenient for ensuring the accuracy of the automatic control of cleaning. The in-place detection member 517 in this embodiment can also adopt a proximity switch. It is worth noting that the number of the cleaning cover member 513, the dust blowing member 514, the dust suction member 515 and the in-place detection member 516 in this embodiment is four, so as to correspond to the number of the cleaning port 512. The number of in-place detection members 517 can be set to two, and the two in-place detection members 517 respectively perform in-place detection on the two outer products, because the products are synchronously moved out from under the reference positioning member 511. When it is known that one of the products has been moved out, it can be inferred that the other products have been moved out. The in-place detection member 516 and the in-place detection member 517 facilitate the cleaning drive component 53 to drive the cleaning component 52 to perform cleaning accurately.

[0060] Re-reference Figure 8, further, the cleaning drive assembly 53 drives the cleaning assembly 52 to move linearly in directions parallel and perpendicular to the cleaning positioning assembly 51 respectively. The cleaning drive assembly 53 includes a first cleaning drive member 531 and a second cleaning drive member 532. The output end of the first cleaning drive member 531 is connected to the second cleaning drive member 532, and the output end of the second cleaning drive member 532 is connected to the cleaning assembly 52. ​​The first cleaning drive member 531 drives the cleaning assembly 52 to move linearly in a direction parallel to the cleaning positioning assembly 51, and the second cleaning drive member 532 drives the cleaning assembly 52 to move linearly in a direction perpendicular to the cleaning positioning assembly 51. The cleaning assembly 52 can accurately clean the product to-be-cleaned parts at the locations of each cleaning port 512 by driving in coordination with the first cleaning drive member 531 and the second cleaning drive member 532. Specifically, the cleaning drive assembly 53 also includes a drive bracket 533. The driving bracket 533 is located on one side of the cleaning positioning bracket 5101, and the first cleaning driving member 531 is arranged at the upper end of the driving bracket 533. The first cleaning driving member 531 in this embodiment is a linear module, which is parallel to the positioning support plate 5102. Specifically, the sequential connection line of the four cleaning ports 512 is a straight line, and the first cleaning driving member 531 is parallel to the straight line, so as to drive the cleaning assembly 52 to pass through the four cleaning ports 512 in sequence. The second cleaning driving member 532 is arranged on the slide of the first cleaning driving member 531. The second cleaning driving member 532 in this embodiment also adopts a linear module, and the cleaning assembly 52 is arranged on the slide of the second cleaning driving member 532, and the cleaning assembly 52 is located directly above the cleaning port 512. The first cleaning driving member 531 drives the second cleaning driving member 532 to move linearly, driving the cleaning assembly 52 to move linearly and making the cleaning assembly 52 stay directly above the cleaning port 512 in sequence, and then the second cleaning driving member 532 drives the cleaning assembly 52 to approach the cleaning port 512, and performs laser cleaning on the to-be-cleaned part of the product in the cleaning cover 513. The cleaning assembly 52 in this embodiment can be a laser cleaning head in the prior art, which is not limited here.

[0061] Re-reference Figure 1 Furthermore, the product after laser cleaning is transported by the conveying device 3 and moved to the sealing nail feeding device 6, and the sealing nail is fed into the liquid injection port of the battery clamped by the clamp 31. The sealing nail feeding device 6 in this embodiment can be a sealing nail feeding device in the prior art. For example, the sealing nail is vibrated and fed by a vibration plate, and then enters the linear vibration. The three-free linear module cooperates with the clamp to grab the sealing nail in the linear vibration and feed it to the liquid injection port of the battery. Preferably, a CCD positioning system is set on the adjacent side of the clamp to facilitate accurate feeding of the sealing nail into the liquid injection port.

[0062] After the sealing nail is loaded, the battery loaded with the sealing nail is conveyed by the conveying device 3 to the position of the pre-welding mechanism 41, and then the lifting assembly 34 lifts the fixture 31 so that the product in the fixture 31 reaches the pre-welding position of the pre-welding mechanism 41, and the pre-welding mechanism 41 pre-welds several welding points between the battery's liquid injection port and the sealing nail, for example, spot welding 3-5 equidistant welding points around the periphery of the liquid injection port, so that the sealing nail is initially fixed at the liquid injection port, and the pre-welding is completed. The pre-welding mechanism 41 in this embodiment can adopt a laser welding mechanism in the prior art, for example, a two-degree-of-freedom or three-degree-of-freedom linear module and a laser welding head. After the pre-welding is completed, the conveying device 3 continues to convey the fixture 31 carrying the product to the position of the full welding mechanism 42, and then the lifting assembly 34 lifts the fixture 31 so that the product in the fixture 31 reaches the full welding position of the full welding mechanism 42, and the full welding mechanism 42 fully welds the battery filling port and the sealing nail, so that the sealing nail is firmly on the battery filling port, and the welding is completed. The full welding mechanism 42 in this embodiment can adopt the laser welding mechanism in the prior art, for example, the cooperation of a linear module with two degrees of freedom or three degrees of freedom and a laser welding head. Preferably, a gantry-type linear module can be used to ensure the stability of the welding head during welding.

[0063] After welding is completed, the conveying device 3 conveys the welded product to the location of the detection device 7 for welding appearance inspection. The detection device 7 in this embodiment can adopt a CCD appearance detection system, which is mainly used to detect whether the weld mark at the welding point between the battery filling port and the sealing pin is complete, and then detect the welding effect. After the inspection is completed, the product is further conveyed to the location of the matching material transfer mechanism 21, and then the clamping assembly 33 opens the clamp, and the matching material transfer mechanism 21 transfers the products that fail the welding inspection to the unqualified product removal mechanism 23 for unloading. For products that pass the welding inspection, the matching material transfer mechanism 21 synchronously pairs and unloads four qualified products to the spacing adjustment mechanism 81, and after the spacing adjustment mechanism 81 adjusts the spacing of the four products, they are transferred to the removal mechanism 82, and then transferred to the next device by the removal mechanism 82.

[0064] Re-reference Figure 1 and Figure 2The pairing unloading process of the pairing material transfer mechanism 21 is similar to its pairing loading process, and it also has two modes: in the first pairing unloading process, if the four batteries first transferred by the fixture 31 are all batteries that have passed the welding inspection, the pairing material transfer mechanism 21 directly transfers the four qualified batteries to the second temporary storage mechanism 24; if there are batteries with unqualified welding among the four batteries first transferred by the fixture 31, the pairing material transfer mechanism 21 transfers the four batteries with qualified welding to the second temporary storage mechanism 24, and transfers the four batteries with unqualified welding to the unqualified product removal mechanism 23. Afterwards, the fixture 31 continues to transfer the subsequent four batteries to the position of the paired material transfer mechanism 21. If the subsequent four batteries are all qualified welding batteries, the paired material transfer mechanism 21 will synchronously transfer the four qualified welding batteries to the spacing adjustment mechanism 81; if there are unqualified welding batteries among the subsequent four batteries, the paired material transfer mechanism 21 will transfer the unqualified welding batteries to the unqualified product removal mechanism 23. At this time, the battery in the fixture 31 is missing, and then the paired material transfer mechanism 21 transfers the corresponding qualified welding batteries from the second temporary storage mechanism 24 to the fixture 31, so that the fixture 31 is filled with four qualified welding batteries. After that, the paired material transfer mechanism 21 transfers the four qualified batteries to the spacing adjustment mechanism 81. In this way, the four batteries synchronously transferred to the spacing adjustment mechanism 81 by the paired material transfer mechanism 21 can all be qualified welding batteries. In the second paired material removal process, the four batteries first transferred by the fixture 31 are all qualified welding batteries, and the paired material transfer mechanism 21 directly transfers the four qualified welding batteries to the spacing adjustment 81. Then, the fixture 31 continues to convey, and when the battery conveyed by the fixture 31 subsequently has a battery with unqualified welding, the paired material transfer mechanism 21 transfers the four batteries with qualified welding to the second temporary storage mechanism 24, and transfers the four batteries with unqualified welding to the unqualified product removal mechanism 23. If there is an unqualified welding battery among the first four batteries conveyed by the fixture 31, the paired material transfer mechanism 21 transfers the four batteries with qualified welding to the second temporary storage mechanism 24, and transfers the four batteries with unqualified welding to the unqualified product removal mechanism 23. The subsequent area completion process is consistent with the first paired material removal process, and will not be repeated here.

[0065] Continue to refer to Fig.12 and Fig.13 , Fig.12 is a schematic diagram of the structure of the spacing adjustment mechanism in this embodiment, Fig.1381 is another structural schematic diagram of the spacing adjustment mechanism in this embodiment. Furthermore, the spacing adjustment mechanism 81 includes an adjustment reference part 811, a spacing adjustment part 812 and an adjustment drive part 813. Among them, the number of the spacing adjustment part 812 is at least one, and at least one spacing adjustment part 812 is adjacent to the adjustment reference part 811. The driving end of the adjustment drive part 813 is connected to at least one spacing adjustment part 812, and the products are respectively carried on the adjustment reference part 811 and at least one spacing adjustment part 812. The adjustment drive part 813 drives at least one spacing adjustment part 812 to approach or move away from the adjustment reference part 811 to adjust the spacing between two adjacent products. By adjusting the reference part 811 and the spacing adjustment part 812 as product carriers, and then the adjustment drive part 813 drives the spacing adjustment part 812, the spacing between the adjustment reference part 811 and the spacing adjustment part 812 carrying the product is adjusted, and the spacing between the adjacent two products can be flexibly adjusted, so that the spacing between the qualified welding products is adapted to the spacing when other equipment is picking up materials when the products are transmitted, so that the products can run smoothly between various production processes, thereby improving production efficiency.

[0066] Re-reference Fig.12 and Fig.13, further, the spacing adjustment mechanism 81 also includes a sliding portion 814. The adjustment reference portion 811 and at least one spacing adjustment portion 812 are respectively slidably connected to the sliding portion 814. The adjustment reference portion 811 and at least one spacing adjustment portion 812 are arranged side by side. The sliding portion 814 is used as a load-bearing and guide for the movement of the spacing adjustment portion 812 to ensure smooth product spacing adjustment. Preferably, the spacing adjustment mechanism 81 also includes a spacing adjustment bracket 816. The spacing adjustment bracket 816 is used to support the spacing adjustment mechanism 81, and at the same time facilitates the spacing adjustment mechanism 81 to be able to dock with the material removal mechanism 82, so that after the spacing adjustment mechanism 81 adjusts the product spacing, it can be smoothly transferred to the material removal mechanism 82. The longitudinal section of the spacing adjustment bracket 816 in this embodiment is approximately U-shaped. The sliding portion 814 includes a guide slide 8141 and a guide rail 8142. The guide slide 8141 is laid on the upper end of the spacing adjustment bracket 816, and the number of guide rails 8142 is two. The two guide rails 8142 are laid on the upper surface of the guide slide 8141 along the length direction of the guide slide 8141, and the two guide rails 8142 are parallel to each other and are respectively located on the opposite sides of the guide slide 8141. The adjustment reference part 811 is arranged on the guide slide 8141 and is directly opposite to the two guide rails 8142. At least one spacing adjustment part 812 is slidably connected to the two guide rails 8142 and is parallel to the adjustment reference part 811. The number of spacing adjustment parts 812 is multiple, and the multiple spacing adjustment parts 812 are arranged side by side and are slidably connected to the guide rails 8142, respectively. In this way, the multiple spacing adjustment parts 812 and the adjustment reference part 811 form a side-by-side position relationship, and after the product is carried on the adjustment reference part 811 and the spacing adjustment part 82, a side-by-side arrangement relationship is also formed accordingly. Such arrangement can facilitate the adjustment of the product spacing and the moving of products in and out. In this embodiment, there are three spacing adjustment parts 812, and the three spacing adjustment parts 812 and one adjustment reference part 811 are used as the bearings of four welding qualified products moved by the matching material transfer mechanism 21.

[0067] Continue to refer to Figure 12 to Figure 14 , Fig.14It is a structural schematic diagram of the spacing adjustment part in this embodiment. Furthermore, the spacing adjustment part 812 includes a bearing seat 8121 and an adjustment linkage part 8122. The adjustment linkage part 8122 is arranged on the bearing seat 8121 and connected to the adjustment reference part 811. The bearing seats 8121 of multiple spacing adjustment parts 812 are arranged side by side, and two adjacent bearing seats 8121 are connected by the adjustment linkage part 8122. The product is specifically carried on the bearing seat 8121. Preferably, the bearing seat 8121 is provided with an adjustment position 81211, and the adjustment linkage part 8122 of one spacing adjustment part 812 is connected to the adjustment position 81211 of another adjacent spacing adjustment part 812. The spacing adjustment between two adjacent bearing seats 8121 is linked by the adjustment linkage part 8122. Preferably, the driving end of the adjustment drive part 813 is connected to the bearing seat 8121 away from the adjustment reference part 811. The adjustment reference portion 811 is stationary. When the adjustment driving portion 813 drives the support seat 8121 away from the adjustment reference portion 811 to move, the adjustment linkage portion 8122 between two adjacent support seats 8121 is linked to drive the remaining adjacent support seats 8121 to adapt and move in turn, and the product spacing is adjusted based on the adjustment reference portion 811, and finally the spacing between two adjacent products is kept consistent. Specifically, the support seat 8121 is a block with a rectangular cross-section. The support seat 8121 includes two first side walls 81212 and two second side walls 81213, wherein the first side wall 81212 is a side wall of the support seat 8121 with a smaller surface area, and the second side wall 81213 is a side wall of the support seat 8121 with a larger surface area. There are two adjustment positions 81211 provided on each bearing seat 8121. The two adjustment positions 81211 are provided on the two first side walls 81212 of the bearing seat 8121, respectively. Specifically, the adjustment position 81211 is in the shape of a strip groove provided on the first side wall 81212. The adjustment position 81211 extends from one end of the first side wall 81212 to the other end of the first side wall 81212. Preferably, a "U"-shaped boss 812111 is formed at the notch of the adjustment position 81211. One end of the "U"-shaped boss 812111 has an opening and is connected to a second side wall 81213, so that the adjustment linkage portion 8122 can pass through the opening of the "U"-shaped boss 812111 and connect with the adjustment position 81211. Specifically, the number of the adjustment linkage parts 8122 of each spacing adjustment part 812 is two, one end of the two adjustment linkage parts 8122 is respectively arranged on the two first side walls 81212 of a bearing seat 8121, and the other ends of the two adjustment linkage parts 8122 are respectively connected to the adjustment position 81211 of another adjacent bearing seat 8121. Specifically, the adjustment linkage part 8122 includes a connecting member 81221, a fixing member 81222 and a linkage member 81223.One end of the connecting member 81221 is fixedly connected to the first side wall 81212 through the fixing member 81222. The connecting member 81221 overlaps with the central axis of the adjustment position 81211, and the connecting member 81221 is located on the side facing away from the opening of the boss 812111. The connecting member 81221 is adapted to the U-shaped boss 812111. The connecting member 81221 in this embodiment is a long strip of plate-like shape, and the fixing member 81222 can be a screw. The linkage member 81223 is arranged at the other end of the connecting member 81221. Specifically, the linkage member 81223 is adapted to the adjustment position 81211. The linkage member 81223 is rotatably connected to the fixing member 81222 through a rotating shaft. In this embodiment, a cam bearing can be used. The linkage member 81223 is rollingly connected to the adjustment position 81211 of the adjacent other first side wall 81212. The two adjusting linkage parts 8122 are provided to realize the linkage relationship between the two adjacent bearing seats 8121. The driving end of the adjusting driving part 813 first drives the bearing seat 8121 away from the adjusting reference part 811 to move toward the adjusting reference part 811, and then drives the linkage part 81223 of the adjusting linkage part 8122 to roll in the adjusting position 81211 in the other adjacent bearing seat 8121. When the linkage part 81223 abuts against the end of the adjusting position 81211, the other bearing seat 8121 will be subjected to the force of the linkage part 81223, thereby driving the other bearing seat 8121 to move toward the adjusting reference part 811, and so on. Push, and then drive the third spacing adjustment part 812 to move toward the adjustment reference part 811, so that the three spacing adjustment parts 812 are close to each other based on the adjustment reference part 811, and finally the spacing between two adjacent products is reduced, and the spacing adjustment is completed. During the adjustment process, the movement stroke of the three spacing adjustment parts 812 is an arithmetic progression. For example, the movement strokes of the three spacing adjustment parts 812 arranged in sequence from away from the adjustment reference part 811 to close to the adjustment reference part 811 are 15cm, 10cm and 5cm respectively. On the contrary, when the adjustment drive part 813 is driven in the reverse direction, the three spacing adjustment parts 812 are driven in sequence away from the adjustment reference part 811, so that the spacing between two adjacent products becomes larger. In this way, the spacing adjustment between the three spacing adjustment parts 812 can be achieved under the single drive of the adjustment drive part 813, and then the spacing adjustment between adjacent products can be achieved, so that the products can rotate in different production processes with different spacings, and only one adjustment drive part 813 is used as the driving source, so that the adjustment of multiple spacing adjustment parts 812 and products can be achieved, which saves energy and reduces enterprise costs. The adjustment driving part 813 in this embodiment may be a cylinder.When the spacing value of the product needs to be adjusted, the new spacing required by the product can be adjusted by changing the rolling stroke of the linkage 81223 in the adjustment position 81211. For example, the length of the connecting member 81221 can be changed by replacing a shorter or longer connecting member 81221 to change the movement stroke of the linkage 81223 in the adjustment position 81211, thereby changing the adjustment stroke of the three spacing adjustment parts 812. Similarly, the length of the adjustment position 81211 can also be changed, and the movement stroke of the linkage 81223 in the adjustment position 81211 can be shortened by adding a pad in the adjustment position 81211.

[0068] Preferably, the surface of the bearing seat 8121 is provided with a sliding member 81214, and the sliding member 81214 is used for assisting the movement of the bearing seat 8121 to carry the product. Specifically, the surface of the bearing seat 8121 is provided with a strip groove, and the strip groove is arranged along the length direction of the bearing seat 8121. The sliding member 81214 includes a plurality of rollers 812141, and the plurality of rollers 812141 are sequentially rotated and connected in the strip groove along the length direction of the strip groove, and the surface of the roller 812141 is exposed in the strip groove, so that a rolling track can be formed on the surface of the bearing seat 8121. When the product is carried on the bearing seat 8121, it is placed on the plurality of rollers 812141, so that when the product moves out of the bearing seat 8121, it forms rolling friction with the surface of the bearing seat 8121, which reduces friction, facilitates the removal of the product, and avoids damage to the product caused by direct friction. Preferably, the spacing adjustment part 812 also includes two limiting guide components 8123. The two limiting guide assemblies 8123 are respectively arranged on the bearing seat 8121. The product is carried on the bearing seat 8121 and is located between the two limiting guide assemblies 8123. The two limiting guide assemblies 8123 limit and guide the product. Through the arrangement of the limiting guide assemblies 8123, it is convenient to limit the product carried by the bearing seat 8121, and when the product moves out of the bearing seat 8121, it can also guide the removal of the product. Preferably, the limiting distance between the two limiting guide assemblies 8123 is adjustable. In this way, the bearing seat 8121 can be adapted to carry products of different specifications and sizes, and the two limiting guide assemblies 8123 can still cooperate to limit and guide products of different specifications and sizes.

[0069] Specifically, two limiting guide assemblies 8123 are respectively arranged on the surface of the bearing seat 8121, and are respectively adjacent to the long side of the bearing seat 8121, and the two limiting guide assemblies 8123 are parallel to each other. Specifically, each limiting guide assembly 8123 includes a plurality of limiting guide members 81231, and the plurality of limiting guide members 81231 are sequentially arranged at intervals along the length direction of the bearing seat 8121. The number of limiting guide members 81231 in this embodiment is three. The limiting guide members 81231 of the two limiting guide assemblies 8123 on the bearing seat 8121 are staggered, and the adjacent limiting guide members 81231 on two adjacent bearing seats 8121 are staggered. The limiting guide member 81231 includes a limiting support block 812311, a limiting adjustment block 812312, a limiting adjustment slot 812313, a limiting guide wheel 812314 and an adjustment fixing member 812315. The position-limiting support block 812311 is arranged on the surface of the bearing seat 8121, the position-limiting adjustment block 812312 is slidably connected to the upper end of the position-limiting support block 812311, the position-limiting adjustment groove 812313 is provided on the position-limiting adjustment block 812312, the position-limiting adjustment groove 812313 is parallel to the bearing seat 8121, the position-limiting guide wheel 812314 is rotatably connected to the upper end of the position-limiting adjustment block 812312 through a rotating shaft, and the position-limiting guide wheel 812314 is parallel to the bearing seat 8121. The position-limiting support block 812311 has a threaded hole at a position corresponding to the position-limiting adjustment groove 812313, and the adjusting fixing member 812315 passes through the position-limiting adjustment groove 812313 and is screwed to the threaded hole of the position-limiting support block 812311. The adjusting fixing member 812315 in this embodiment can be a screw. When the adjustment fixing 812315 is released, the limit adjustment block 812312 can be slid to make the limit adjustment groove 812313 move relative to the adjustment fixing 812315, thereby realizing the position adjustment of the limit guide wheel 812314, thereby realizing the adjustment of the limit position between the two limit guide components 8123. After the adjustment is completed, the adjustment fixing 812315 is locked again, so that the limit guide wheel 812314 can be fixed in the adjusted position. In this way, the multiple limit guide wheels 812314 of the two limit guide components 8123 are formed to limit the product. When the product specifications and dimensions change, the adjustment fixing 812315 can be loosened to adjust the product. The structure and working principle of the adjustment reference part 811 in this embodiment are similar to those of the spacing adjustment part 812. The difference between the two is that the adjustment reference part 811 does not have an adjustment linkage part 8122, and the rest is consistent with the structure and spacing adjustment part 812, which will not be repeated here.

[0070] Preferably, the spacing adjustment mechanism 81 in this embodiment also includes a transfer part 815. The transfer part 815 is used to adjust the transfer of the products carried by the reference part 811 and at least one spacing adjustment part 812. Preferably, the transfer part 815 includes a transfer drive member 8151 and a transfer member 8152, the driving end of the transfer drive member 8151 is connected to the transfer member 8152, the transfer drive member 8151 drives the transfer member 8152, and the transfer member 8152 drives the product to move out from the adjustment reference part 811 and the spacing adjustment part 812. Specifically, the transfer part 815 also includes two transfer support frames 8153 and two transfer guide rails 8154. The two transfer support frames 8153 are respectively arranged on the upper surface of the guide slide 8141, and are respectively opposite to the two ends of the guide slide rail 8142. The transfer support frame 8153 is perpendicular to the guide slide rail 8142. Two transfer rails 8154 are respectively laid on the upper ends of the two transfer support frames 8153, and the transfer rails 8154 are perpendicular to the guide rails 8142. The transfer member 8152 is slidably connected to the two guide rails 8142 and is located above the limiting guide assembly 8123. After the product is carried on the bearing seat 8121, the transfer member 8152 is directly opposite to the product. The battery product in this embodiment is vertically placed on the bearing seat 8121, so the battery product and the transfer member 8152 form a vertical relationship. The transfer drive member 8151 is supported on the side wall of the guide slide 8141 by a support frame. The output end of the transfer drive member 8151 is connected to the transfer member 8152, which drives the transfer member 8152 to slide on the transfer rails 8154. The transfer member 8152 pushes the adjustment reference portion 811 and the product carried by the spacing adjustment portion 812 to move out of the bearing portion 2 and the adjustment reference portion 811. The transfer driving member 8151 in this embodiment is a cylinder, and the transfer member 8152 is in the shape of an elongated plate. Preferably, the transfer portion 815 also includes two limit buffers 8155, which are respectively arranged at the upper end of the transfer support frame 8153 and respectively located at the opposite ends of the transfer guide rail 8154, and the two limit buffers 8155 are used to limit and buffer the movement of the transfer member 8152. The limit buffer 8155 in this embodiment can be a buffer. Preferably, the number of the limit buffers 8155 is four, and two limit buffers 8155 are arranged on each transfer support frame 8153, which are respectively used to limit and buffer the two ends of the transfer member 8152.In specific applications, the spacing adjustment mechanism 81 is arranged at the starting end of the material removal mechanism 82. The material removal mechanism 82 in this embodiment is a conveyor line mechanism. The surface of the support seat 8121 is flush with the surface of the conveyor line of the material removal mechanism 82. The four qualified welding products are first grabbed by the matching transfer mechanism 21 and placed on the adjustment reference part 811 and the three spacing adjustment parts 812. Then the adjustment drive part 813 drives the three spacing adjustment parts 812 in sequence to adjust the spacing of the products, so that the spacing between two adjacent products is respectively expanded or reduced and kept consistent to adapt to the spacing size required for the next process to take materials. Then the transfer drive part 8151 drives the transfer part 8152 to push the four products after the spacing adjustment to be transferred to the conveyor line of the material removal mechanism 82. The conveyor line conveys the four products to the location of the next process equipment. The manipulator of the next process equipment grabs the four products after the spacing adjustment and enters the next process to continue the operation. In this way, the material taking spacing requirements for different products between the two production process equipment are solved, the smoothness of product flow is increased, and the production efficiency is improved.

[0071] Re-reference Figure 1 Furthermore, the material removal device 8 also includes a material removal detection mechanism 83. The material removal detection mechanism 83 includes a material removal detection component 831 and a detection display 832. The material removal detection component 831 is arranged on one side of the material removal mechanism 82 through a support frame, and the detection end of the material removal detection mechanism 831 is located above the material removal mechanism 82, which takes photos of the products passing through. The material removal detection component 831 in this embodiment includes four CCD cameras arranged side by side, which respectively take photos of the overall appearance of four welding qualified products transmitted by the material removal mechanism 82. The material removal detection component 831 is connected to the detection display 832, and the product photos taken by the material removal detection component 831 are transmitted to the detection display 832. After being magnified by the detection display 832, the product pictures are manually inspected for appearance to determine whether the product appearance is qualified, and unqualified products are promptly eliminated to avoid being transmitted to the equipment of the next process. The detection display 832 in this embodiment can adopt an industrial machine with a display screen, which can magnify four products side by side respectively for manual visual inspection.

[0072] In summary, the welding equipment of the present application can timely eliminate unqualified products to be welded while ensuring efficient welding, avoiding waste of welding resources, and can adjust the spacing between multiple products being cut, thereby enhancing the compatibility of the welding equipment of the present application with other equipment.
