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.

[0030] 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.

[0031] 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.

[0032] 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:

[0033] Reference Figure 1 , Figure 1 Schematic diagram of the structure of the welding machine in this embodiment. The welding machine in this embodiment includes a machine platform 100, a fixture 1 and a welding device 4. The fixture 1 is fixed on the machine platform 100. The welding device 4 is movably arranged on the machine platform 100, and the welding device 4 is located on one side of the fixture 1, and welds the product in the fixture 1.

[0034] By fixing the fixture 1 on the machine 100, the movable layout of the welding device 4 is performed based on the fixture 1 set at a fixed point as a reference, thereby avoiding the problem of error superposition caused by the movement of multiple mechanisms, improving the welding accuracy, and further improving the welding quality; in addition, the risk of movement interference of the internal mechanism of the welding machine is reduced, making the layout of the welding machine more simplified and reducing the occupied space of the welding machine. The product in this embodiment has two parts to be welded, and the two parts to be welded are pressed together and welded to form a product.

[0035] Re-reference Figure 1Furthermore, the welding machine in this embodiment also includes a feeding device 2 and a transfer device 3. The feeding device 2 is adjacent to the jig 1. The transfer device 3 is located above the jig 1 and adjacent to the feeding device 2. The feeding device 2 is used for loading products. The transfer device 3 receives the loaded products and transfers the products to the jig 1. The products loaded by the feeding device 2 are transferred to the jig 1 by the transfer device 3, so that the automatic loading of the products is realized and the movement of the jig 1 to receive the products is avoided. It is worth noting that the products loaded by the feeding device 2 are two parts to be welded assembled together, but not pressed.

[0036] Re-reference Figure 1 Furthermore, there are multiple jigs 1, and multiple jigs 1 are sequentially arranged on the machine 100 along the length direction of the machine 100, so as to form a jig line on the surface of the frame 100. One end of the feeding device 2 is arranged at one end of the machine 100, and is close to the first jig 1 among the multiple jigs 1, and the other end of the feeding device 2 extends in a direction away from the jig 1. The transfer device 3 is arranged on the machine 100, and is located above the jig 1 and the feeding device 2. The transfer device 3 in this embodiment spans across multiple jigs 1 to form a jig line. The welding device 4 is slidably arranged on the machine 100, and is located on one side of the jig 1. The welding device 4 in this embodiment is parallel to the jig line formed by the multiple jigs 1.

[0037] Refer to Figure 2 , Figure 2 Schematic diagram of the structure of the jig and the dust removal device in this embodiment. Furthermore, the welding machine in this embodiment also includes a dust removal device 5. The dust removal device 5 is arranged on the jig 1. The dust removal device 5 is used to remove dust from the product. The product is dusted by the dust removal device 5 to avoid the influence of dust on the product, thereby ensuring the welding quality of the product. The jig 1 in this embodiment can adopt the structure of the existing welding jig, which has a structure for press-fitting and positioning the two parts to be welded of the product.

[0038] Re-reference Figure 1 Furthermore, the welding machine in this embodiment also includes a detection device 6. The detection device 6 is located between the jig 1 and the welding device 4, and the detection device 6 is used to detect the steps between the parts to be welded before the product is welded. The detection device 6 in this embodiment is arranged on the machine table 100 and is parallel to the welding mechanism 4. If the step between the two parts to be welded of the product is high, it will affect the welding effect of the product. The step between the two parts to be welded of the product is detected by the detection device 6, and unqualified products with large steps are eliminated in time, which also avoids the production of defective welding products and saves welding resources.

[0039] Re-reference Figure 1Furthermore, in this embodiment, the welding machine further includes a feeding device 7. The feeding device 7 is located on the side of the fixture 1 away from the feeding device 2. The transfer device 3 transfers the product to the feeding device 7, and the feeding device 7 is used for feeding the product. Specifically, one end of the feeding device 7 is arranged at the other end of the machine 100 and is close to the last fixture 1 among the multiple fixtures 1. The automatic feeding of the product is achieved by the setting of the feeding device 7.

[0040] Refer to Figure 3 , Figure 3 It is a schematic diagram of the structure of the feeding device in this embodiment. The feeding device 2 includes an incoming material driving mechanism 21 and an incoming material product adjustment mechanism 22. The driving end of the incoming material driving mechanism 21 is connected to the incoming material product adjustment mechanism 22. The incoming material driving mechanism 21 drives the incoming material product adjustment mechanism 22 to approach or move away from the transfer device 3, and the incoming material product adjustment mechanism 22 is used for adjusting the product before transfer and feeding. The product before feeding is adjusted by the incoming material product adjustment mechanism 22 to facilitate subsequent product transfer, fixture positioning and welding. Preferably, the feeding device 2 also includes a code scanning mechanism 23. The code scanning mechanism 23 is located on one side of the incoming material product adjustment mechanism 22, and is used to scan the product for subsequent production management.

[0041] Specifically, the incoming material driving mechanism 21 can adopt an existing linear driver, such as a linear module, which is not limited here. The incoming material product adjustment structure 22 includes an adjustment carrier plate 221 and an incoming material product adjustment component 222. The adjustment carrier plate 221 is arranged at the driving end of the incoming material driving mechanism 21, for example, on the slide of the linear module. The incoming material product adjustment component 222 is arranged on the adjustment carrier plate 221, and the external product is placed in the adjustment position of the incoming material product adjustment component 222, and then, the incoming material driving mechanism 21 drives the adjustment carrier plate 221 to be close to the transfer device 3, driving the product on the incoming material product adjustment component 222 to be transferred synchronously.

[0042] The incoming product adjustment assembly 222 includes an adjustment support 2221, a first adjustment reference member 2222, a first adjustment member 2223, a second adjustment reference member 2224, a second adjustment member 2225, and a product in-position sensor 2226. The adjustment support 2221 is arranged on the adjustment support plate 221. The adjustment support 2221 in this embodiment is plate-shaped, and a product carrier 22211 is provided on the adjustment support 2221. The product in-position sensor 2226 is embedded in the product carrier 22211. The product in-position sensor 2226 in this embodiment is a proximity sensor, and the product in-position sensor 2226 is used to detect the presence or absence of a product. The first adjustment reference member 2222 is arranged on the adjustment support 2221 and is located on one side of the product carrier 22211. The first adjustment reference member 2222 in this embodiment is block-shaped. The first adjustment member 2223 is arranged on the adjustment bearing member 2221 and is located on a side of the product bearing platform 22211 away from the first adjustment reference member 2222. The first adjustment member 2223 includes a first adjustment driver 22231 and a first adjustment block 22232. The output end of the first adjustment driver 22231 is connected to the first adjustment block 22232. The first adjustment block 22232 is directly opposite to the first adjustment reference member 2222. The first adjustment driver 22231 drives the first adjustment block 22232 to move linearly, so that the first adjustment block 22232 approaches or moves away from the first adjustment reference member 2222. The first adjustment driver 22231 in this embodiment is a cylinder. The second adjustment reference member 2224 is arranged on the adjustment bearing member 2221 and is located on a side of the product bearing platform 22211. The second adjustment reference member 2224 is adjacent to the first adjustment reference member 2222. The second adjustment reference member 2224 in this embodiment is block-shaped and perpendicular to the first adjustment reference member 2222. The second adjustment member 2225 is arranged on the adjustment support member 2221 and is located on the side of the product support platform 22211 away from the second adjustment reference member 2224. The second adjustment member 2225 includes a second adjustment driver 22251 and a second adjustment block 22252. The output end of the second adjustment driver 22251 is connected to the second adjustment block 22252, and the second adjustment block 22252 is directly opposite to the second adjustment reference member 2224. The second adjustment driver 22251 is a cylinder, which drives the second adjustment block 22252 to move linearly, so that the second adjustment block 22252 approaches or moves away from the second adjustment reference member 2224. The direction of linear movement of the first adjustment block 22232 is perpendicular to the direction of linear movement of the second adjustment block 22252. In this embodiment, after the two components to be welded are assembled, they are placed on the product support platform 22211, and one of the components to be welded faces the second adjustment block 22252.The linearly movable first adjustment block 22232 clamps and positions the opposite sides of the other welding component with the first adjustment reference part 2222 as a reference, and then the linearly movable second adjustment block 22252 pushes a component to be welded into place with the second adjustment reference part 2224 as a reference. At this time, the second adjustment block 22252 and the second adjustment reference part 2224 are not clamped, but only pushed into place, so that the two components to be welded can be assembled in the correct posture.

[0043] The number of the incoming product adjustment components 222 in this embodiment is two, and the two incoming product adjustment components 222 are sequentially arranged on the adjustment bearing plate 221, so as to realize the feeding adjustment of two products. Preferably, the feeding device 2 also includes a spacing adjustment component 24. The adjustment bearing member 2221 of one of the incoming product adjustment components 222 is slidably connected to the adjustment bearing plate 221, and the output end of the spacing adjustment component 24 is connected to the adjustment bearing member 2221. The spacing adjustment component 24 is a cylinder, which drives the adjustment bearing member 2221 to move linearly, thereby adjusting the spacing between the two incoming product adjustment components 222, and completing the adjustment of the feeding spacing of the two products, so that the clamping spacing when the transfer device 3 synchronously transfers two products can be adapted.

[0044] The code scanning mechanism 23 includes a code scanning drive component 231, a code scanning gun 232 and a code scanning slide 233. The code scanning slide 233 is located on one side of the two incoming product adjustment components 222. The code scanning slide 233 is in the shape of a plate and is slidably connected to the adjustment support plate 221. The code scanning gun 232 is arranged on the code scanning slide 233. The code scanning drive component 231 is a cylinder, and its driving end is connected to the code scanning slide 233. It drives the code scanning slide 233 to move linearly, driving the code scanning gun 232 to move linearly, so that the code scanning gun 232 can scan the products in the two incoming product adjustment components 222. In this way, a single code scanning gun 232 can scan the products in the two incoming product adjustment components 222, and the cost is relatively low.

[0045] Continue to refer to Figure 1 and Figure 4 , Figure 4 In this embodiment Figure 1 Further, the transfer device 3 includes a transfer bearing mechanism 31, two transfer mechanisms 32 and two gripping mechanisms 33. The two gripping mechanisms 33 are respectively arranged on the two transfer mechanisms 32, and the two transfer mechanisms 32 move on the transfer bearing mechanism 31 respectively, driving the two gripping mechanisms 33 to move synchronously, and the two gripping mechanisms 33 are respectively used for loading and unloading products. The two gripping mechanisms 33 are transferred respectively by the two transfer mechanisms 32, so that the two gripping mechanisms 32 can divide the work of loading and unloading the products in the fixture 1, thereby improving the loading and unloading efficiency.

[0046] Specifically, the transfer bearing mechanism 31 is a gantry structure, which has a beam portion 311. The transfer bearing mechanism 31 is arranged on the machine 100, the beam portion 311 is located above the fixture 1, and spans the fixture line formed by multiple fixtures 1, and the beam portion 311 is plate-shaped, which is perpendicular to the machine 100. The transfer mechanism 32 includes a transfer bearing assembly 321, a transfer track assembly 322, a transfer transmission assembly 323 and a transfer drive assembly 324. The transfer track assembly 322 is laid on the beam portion 311 along the length direction of the beam portion 311. The transfer track assembly 322 in this embodiment is two slide rails arranged side by side. The transfer bearing assembly 321 is slidably connected to the beam portion 311 through the transfer track assembly 322. The transfer bearing assembly 321 in this embodiment is plate-shaped. The transfer transmission assembly 323 includes a rack member 3231 and a gear member (not shown) meshed with the rack member 3231. The rack member 3231 is a track with tooth patterns, which is laid on the crossbeam 311 and is located between the two slide rails of the transfer track assembly 322. The rack member 3231 is parallel to the slide rail, and the gear member is a gear. The transfer drive assembly 324 is a motor, which is arranged on the transfer bearing assembly 321. The output end of the transfer drive assembly 324 passes through the transfer bearing assembly 321 and is connected to the gear member. The gripping mechanism 33 is arranged on the transfer bearing assembly 321 and is located on one side of the transfer drive assembly 324. The transfer drive assembly 324 drives the gear member, so that the gear member meshes and transmits on the rack member 3231, driving the transfer bearing assembly 321 to move linearly on the transfer track assembly 322, so that the gripping mechanism 33 moves linearly synchronously. In this way, the two grabbing mechanisms 33 can respectively move linearly to grab the loading or unloading materials. The grabbing mechanism 33 in this embodiment can be a combination of a linear module and an existing grabbing structure, which will not be described in detail here.

[0047] Re-reference Figure 1, further, the welding device 4 includes a welding drive mechanism 41 and a welding mechanism 42. The output end of the welding drive mechanism 41 is connected to the welding mechanism 42, which drives the welding mechanism 42 to approach or move away from the product, and the welding mechanism 42 welds the product. Specifically, the welding drive mechanism 41 includes a first welding drive assembly 411 and a second welding drive assembly 412, the output end of the first welding drive assembly 411 is connected to the second welding drive assembly 412, and the output end of the second welding drive assembly 412 is connected to the welding mechanism 42. The first welding drive assembly 411 drives the welding mechanism 42 to move linearly along a direction parallel to the fixture 1, and the second welding drive assembly 412 drives the welding mechanism 42 to approach or move away from the product, and the welding mechanism 42 welds the product. Through the cooperation of the first welding drive assembly 411 and the second welding drive assembly 412, the welding mechanism 42 realizes the motion welding of multiple fixed fixtures 1, reduces interference, and improves welding quality and efficiency. Specifically, the first welding drive assembly 411 is arranged on the machine 100 and is parallel to the fixture line formed by multiple fixtures 1. The second welding drive assembly 412 is arranged on the first welding drive assembly 411. The first welding drive assembly 411 can adopt an existing linear driver, which drives the second welding drive assembly 412 to move linearly in a direction parallel to the jig 1. The welding mechanism 42 is connected to the output end of the second welding drive assembly 412. The second welding drive assembly 412 in this embodiment can adopt the cooperation of two linear modules, one linear module drives the welding mechanism 42 to move linearly in a direction perpendicular to the jig 1, and the other linear module drives the welding mechanism 42 to move linearly in a direction perpendicular to the machine 100. In this way, the welding drive mechanism 41 can drive the welding mechanism 42 to approach any jig 1 among the multiple jigs 1, and weld the parts to be welded of the product in the corresponding jig 1. The welding mechanism 42 in this embodiment is a laser welding machine.

[0048] Continue to refer to Figure 2 and Figure 5 , Figure 5 It is a structural schematic diagram of the dust removal device of this embodiment. Furthermore, the dust removal device 5 includes a first dust removal mechanism 51 and a second dust removal mechanism 52. The first dust removal mechanism 51 and the second dust removal mechanism 52 cooperate to remove the press dust and welding smoke of the parts to be welded of the product. It can be understood that after the fixture 1 is fixed, the first dust removal mechanism 51 and the second dust removal mechanism 52 can both lay out the dust removal pipeline from the fixture 1, so that the layout of the dust removal pipeline is simpler, and the risk of interference of the pipeline layout with other mechanisms in the welding machine can be further avoided, thereby reducing the occupied space of the welding machine.

[0049] Specifically, the jig 1 includes a jig body 11, a press-fitting part 12 and a jig frame 13. The jig body 11 and the press-fitting part 12 are respectively arranged on the jig frame 13, wherein the jig body 11 and the press-fitting part 12 respectively adopt the existing jig structure and the press-fitting structure, the product transferred by the transfer device 3 is transferred to the jig body 11, and the press-fitting part 12 presses the two parts to be welded of the product.

The dust removal installation mechanism 50 can be installed on the jig frame 13, and the dust removal installation mechanism 50 faces the position of the product in the jig body 11 and is adjacent to the press-fitting part 12. The installation mechanism 50 in this embodiment is plate-shaped, and the first dust removal mechanism 51 includes a dust collecting part 511 and a first dust suction part 512. The dust collecting part 511 is arranged on the side of the installation mechanism 50 facing the jig body 11, and the press-fitting part 12 is located above the dust collecting part 511. The dust collecting part 511 in this embodiment is a funnel-shaped with a triangular longitudinal section.

The second dust removal mechanism 52 includes a dustproof part 521 and a second dust suction part 522. The dustproof part 521 is provided at the upper end of the dust removal installation mechanism 50. The dustproof part 521 in this embodiment is box-shaped, and a welding opening 5211 is provided along its length direction. The second dust suction part 522 is tubular, and there are two of them. One end of the two second dust suction parts 522 is respectively connected to the two opposite ends of the dustproof part 521, and the other end thereof extends in a direction away from the dust removal installation mechanism 50. Preferably, the dust removal device 5 also includes a dust collection mechanism 53. The dust collection mechanism 53 is tubular, one end of which is respectively connected to the first dust suction part 512 and the end of the second dust suction part 522 away from the dust removal installation mechanism 50, and the other end of the dust collection mechanism 53 is connected to a dust suction mechanism, for example, a suction fan. Preferably, the dust removal device 5 also includes a shock absorbing and buffering mechanism 54.

The shock absorbing and buffering parts 541 can use existing shock absorbers for shock absorbing and buffering during dust removal. The pressing part 12 presses the two parts to be welded above the dust collecting part 511, and most of the pressing dust generated is sucked out through the dust collecting part 511, the first dust suction part 512 and the dust collecting mechanism 53 in turn, and part of it is sucked out through the dust prevention part 521, the second dust suction part 522 and the dust collecting mechanism 53; the two pressed parts to be welded are transferred by the fixture body 11 through the welding port 5211 and placed in the second dust suction part 522. At this time, the welding mechanism 42 performs laser welding on the two pressed parts to be welded through the welding port 5211, and most of the welding fumes generated are sucked out through the dust prevention part 521, the second dust suction part 522 and the dust collecting mechanism 53 in turn, and part of it is sucked out through the dust collecting part 511, the first dust suction part 512 and the dust collecting mechanism 53.

[0050] Continue to refer to Figure 1 and Figure 6 , Figure 6 6 is a schematic diagram of the structure of the detection device in this embodiment. Furthermore, the detection device 6 includes a detection drive mechanism 61 and a detection mechanism 62. The driving end of the detection drive mechanism 61 is connected to the detection mechanism 62, which drives the detection mechanism 62 to approach or move away from the product, and the detection mechanism 62 detects the steps between the parts to be welded before the product is welded. The detection of the steps between the parts to be welded in the multiple jigs 1 can be realized by the cooperation of the detection drive mechanism 61 and the detection mechanism 62.

[0051] Specifically, the detection device 6 also includes a detection bearing mechanism 60. The detection bearing mechanism 60 is also a gantry structure, which is arranged on the surface of the machine 100 and is located between the fixture 1 and the welding device 4. The crossbeam of the detection bearing mechanism 60 is parallel to the crossbeam portion 311 of the transfer bearing mechanism 31. The detection drive mechanism 61 is slidably connected to the crossbeam of the detection bearing mechanism 60, and the detection mechanism 62 is arranged on the detection drive mechanism 61. The structure and actuation principle of the detection drive mechanism 61 in this embodiment are consistent with the structure and actuation principle of the transfer mechanism 32, and are not repeated here. The detection drive mechanism 61 drives the detection mechanism 62 to move linearly along the crossbeam of the detection bearing mechanism 60, so that the detection mechanism 62 faces the products in different fixtures 1 respectively. The detection mechanism 62 in this embodiment includes a detection drive component 621, a detection bearing component 622 and a detection component 623. The detection drive component 621 is arranged on the detection drive mechanism 61, the detection bearing component 622 is slidably connected to the detection drive mechanism 61, and the detection component 623 is arranged on the detection bearing component 622. The output end of the detection drive component 621 is connected to the detection bearing component 622, which drives the detection bearing component 622 to move linearly along a direction perpendicular to the machine 100, driving the detection component 623 to move linearly synchronously. The detection drive component 621 in this embodiment is a cylinder, the detection bearing component 622 is plate-shaped, and the detection component 623 can be used as a 3D profiler or a 2D laser displacement sensor to detect the height step difference between two parts of the product. In specific applications, the detection component 623 first detects the step between the parts to be welded of the product. If the step height, that is, the height difference between the two parts to be welded is within the allowable range, the welding mechanism 42 performs welding, otherwise, no welding is performed, and the product is treated as a defective product. It can be understood that at the first two ends of the detection bearing mechanism 60, the detection component 623 will interfere with the welding mechanism 42. At this time, the detection drive component 621 needs to lift the detection component 623 first, and then weld, and then the detection drive component 621 resets and lifts the detection component 623.

[0052] Re-reference Figure 1, further, the unloading device 7 includes a flipping mechanism 71, a transfer mechanism 72, a good product unloading mechanism 73 and a bad product unloading mechanism 74. The flipping mechanism 71, the good product unloading mechanism 73 and the bad product unloading mechanism 74 are respectively arranged on the transfer path of the transfer mechanism 72. The flipping mechanism 71 is adjacent to the transfer device 3. The transfer device 3 transfers the product to the flipping mechanism 71, the flipping mechanism 71 flips the product and transfers the product to the transfer mechanism 72, and the transfer mechanism 72 transfers the product to the good product unloading mechanism 73 or the bad product unloading mechanism 74. Through the cooperation of the flipping mechanism 71 and the transfer mechanism 72, good products and bad products are unloaded through the good product unloading mechanism 73 and the bad product unloading mechanism 74 respectively, so that the subsequent good products can perform subsequent processes and the bad products can be dispersed.

[0053] Continue to refer to Figure 1 and Figure 7 , Figure 7Schematic diagram of the structure of the flip mechanism in this embodiment. Furthermore, the flip mechanism 71 is arranged on the machine 100 and is located on the side of the jig 1 away from the feeding device 2, and the flip mechanism 71 is located below the gripping mechanism 33. Specifically, the flip mechanism 71 includes a flip carrier 711, a flip slide 712, a linear drive member 713, a flip frame 714, a rotary drive member 715 and a stabilizing member 716. The flip carrier 711 is arranged on the machine 100, which is approximately a gantry structure. The flip slide 712 includes a bottom plate 7121 and two vertical plates 7122. The bottom plate 7121 is slidably connected to the two vertical beams of the flip carrier 711, and the two vertical plates 7122 are respectively perpendicular to the surface of the bottom plate 7121 and are respectively located at opposite ends of the bottom plate 7121. The cross-section of the bottom plate 7121 and the two vertical plates 7122 is approximately U-shaped. The linear drive member 713 is arranged on the crossbeam of the flip carriage 711, and its output end is connected to the bottom plate 7121 of the flip slide frame 712. The linear drive member 713 is a cylinder, which drives the flip slide frame 712 to move linearly along a direction perpendicular to the machine 100. The two ends of the flip frame 714 are respectively rotatably connected to the two vertical plates 7122. The rotary drive member 715 is a rotary cylinder, which is arranged on the bottom plate 7121 of the flip slide frame 712, and its output end passes through the vertical plate 7122 and is connected to the flip frame 714, and the rotary drive member 715 drives the flip frame 714 to rotate. The number of the stabilizing members 716 in this embodiment is two, and the two stabilizing members 716 are arranged on the flip frame 714 in sequence. Each stabilizing member 716 includes a stabilizing plate 7161, a plurality of suction cups 7162 embedded in the stabilizing plate 7161, a sensing sensor 7163 embedded in the stabilizing plate 7161, a bidirectional driving cylinder 7164 disposed on the stabilizing plate 7161, and two clamps 7165 respectively connected to the output ends of the bidirectional driving cylinder 7164. The plurality of suction cups 7162 are evenly distributed on the stabilizing plate 7161, the two clamps 7165 are respectively located on opposite sides of the stabilizing plate 7161, and the bidirectional driving cylinder 7164 drives the two clamps 7165 to move closer to or away from each other. The transfer mechanism 72 is disposed on the machine 100 and is located below the flip carrier 711. The transfer mechanism 72 includes a transfer drive assembly 721 and a transfer assembly 722. The transfer drive assembly 721 is laid on the machine 100 and vertically passes through the flip carrier 711. The output end of the transfer drive assembly 721 is connected to the transfer assembly 722. In this embodiment, the transfer drive assembly 721 can use an existing linear drive, such as a linear module. The transfer assembly 722 is set on the slide of the transfer drive assembly 721. The transfer drive assembly 721 drives the transfer assembly 722 to move linearly. The transfer assembly 722 in this embodiment can use a conveyor belt. In this embodiment, an existing conveyor belt with a limiting wheel can be used, which can carry and transport the battery vertically.The good product unloading mechanism 73 and the bad product unloading mechanism 74 are both conveyor belts with limiting wheels, and the good product unloading mechanism 73 and the bad product unloading mechanism 74 are respectively located on opposite sides of the flip carrier 711, and the feeding ends of the good product unloading mechanism 73 and the bad product unloading mechanism 74 are adapted to the transfer component 722. When the moving component 722 moves to the good product unloading mechanism 73 and the bad product unloading mechanism 74 respectively, they can be adapted to be connected with the good product unloading mechanism 73 and the bad product unloading mechanism 74 respectively. The product unloaded by the grasping mechanism 33 is transferred to the stable plate 7161. After the induction sensor 7163 senses the product, the suction cup 7162 adsorbs the product, and the two-way driving cylinder 7164 drives the two clamping claws 7165 to approach each other to clamp the product. Then, the rotary drive component 715 drives the flip frame 714 to rotate 90 degrees, so that the product corresponds to the top of the transfer component 722 of the transfer mechanism 72, and the linear drive component 713 drives the flip sliding frame 712 to descend, and the suction cup 7162 and the two clamps 7165 release the product and transfer the product to the transfer component 722. Then, the transfer drive component 721 moves the product to the good product unloading mechanism 73 and the defective product unloading mechanism 74 for unloading according to whether the product is a good product.

[0054] The welding process of the welding machine in this embodiment is as follows: the loading device 2 loads the product, the transfer device 3 transfers the product to the fixture 1, the detection device 6 detects the steps of the parts to be welded of the product, and if the product is qualified, the welding device 4 performs laser welding, and the dust removal device 5 performs dust removal at the same time. If the product is unqualified, no welding process is performed. After that, the transfer device 3 transfers the product to the flip mechanism 71, the flip mechanism 71 flips the product and moves it to the transfer mechanism 72, and the transfer mechanism 72 moves the qualified product to the good product unloading mechanism 73 for unloading, and the unqualified product is transferred to the defective product unloading mechanism 74 for unloading.

[0055] In summary, the fixture is fixed on the machine table, and the fixed-point fixture is used as a reference for the active layout of the welding device, which avoids the error superposition problem caused by the movement of multiple mechanisms, improves the welding accuracy, and further improves the welding quality. In addition, the layout of other mechanisms around the fixture also reduces the risk of movement interference of the internal mechanisms of the welding machine, making the layout of the welding machine simpler and reducing the space occupied by the welding machine.
