[0027] The technical solution of the present invention will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work belong to the protection scope of the present invention.

[0028] An automatic spot welding machine, such as Figure 1 and Figure 2 As shown, it includes a machine platform 1, a mounting base 2, a transmission mechanism 3, a welding mechanism 5, a spot welding fixture 6 and a wire pulling mechanism 4. The machine platform 1 is used to carry various components, the mounting base 2 provides a suitable installation position for the welding mechanism 5 and the wire pulling mechanism 4, the spot welding fixture 6 is used to clamp the product to be spot welded, and the transmission mechanism 3 transmits the spot welding fixture 6 to a predetermined position for processing. The transmission mechanism 3 and the mounting base 2 are arranged on the machine platform 1 in front and behind. Figure 1 The transmission mechanism 3 is set in front of the mounting base 2 with the direction as reference. The spot welding fixture 6 is connected to the transmission mechanism 3 by transmission. The transmission mechanism 3 transmits the spot welding fixture 6 to the spot welding position and transmits it out after the spot welding is completed. The welding mechanism 5 is fixed on the mounting base 2 and located above the transmission mechanism 3. The welding mechanism 5 spot welds the product from top to bottom. The wire pulling mechanism 4 is fixed on the mounting base 2 and located below the welding mechanism 5. The wire pulling mechanism 4 corresponds to the product position on the spot welding fixture 6 to ensure that the wire pulling mechanism 4 can horizontally straighten the tail wire of the product.

[0029] Specifically, Figure 3 As shown in the figure, after the wires are wound on the product, they extend from both ends and need to be fixed to the product by spot welding. Figure 1 and Figure 2 As shown, Figure 3 The product to be spot welded is placed on the spot welding fixture 6, the transmission mechanism 3 transmits the spot welding fixture 6 to the position of the mounting base 2, the wire pulling mechanism 4 clamps the tail of the wire of the product and moves backward to straighten the wire and locate it at the spot welding position of the product, and the welding mechanism 5 then spot welds the product, which can not only ensure that the wire is located at the predetermined spot welding position, so that the quality of the product spot welding is guaranteed, but also realize fully automated spot welding of the product to replace manual labor, which can greatly improve production efficiency and ensure product consistency.

[0030] An automatic spot welding machine provided in this embodiment, such as Figure 4As shown, the welding mechanism 5 includes a welding base 51, a welding moving part 52, a welding assembly 53 and a buffer cylinder assembly 54. The welding base 51 is used to load the welding moving part 52, and the welding moving part 52 drives the welding assembly 53 to move and align. The welding moving part 52 includes movement in the front-back direction, the up-down direction and the left-right direction, and preferably moves in a relative sliding manner between the slider and the slide rail. The welding assembly 53 is fixed on the slider to slide with the welding moving part 52. The welding base 51 is fixed on the mounting base 2, the welding moving part 52 is fixedly mounted on the welding base 51, the buffer cylinder assembly 54 is fixed on the welding moving part 52 and moves with the welding moving part 52, and the welding assembly 53 is fixed on the buffer cylinder assembly 54. Specifically, the welding assembly 53 is driven by the welding movable part 52 to align the product welding position, and the buffer cylinder assembly 54 pushes the welding assembly 53 slowly downward to contact the product. When the welding assembly 53 is subjected to the reaction force of the product, it can also retract against the buffer cylinder assembly 54. In this way, through the buffering effect of the buffer cylinder assembly 54, direct rigid contact can be avoided to avoid the product to be welded from being crushed, thereby greatly improving the yield rate in the product production and processing process, and facilitating the control of the pressure of the product during welding.

[0031] An automatic spot welding machine provided in this embodiment, such as Figure 5 As shown, the welding assembly 53 includes a welding seat 531, a welding head 532, a cutter seat 533, a cutter 534, a wire hanging seat 535 and a wire hanging column 536. The welding head 532 is fixed to the bottom of the welding seat 531, the cutter seat 533 is fixed on the outer side of the welding seat 531, the cutter 534 is fixed to the bottom of the cutter seat 533, the wire hanging seat 535 is fixed to the bottom of the cutter seat 533 and avoids the cutter 534, and the wire hanging column 536 The wire hanging seat 535 is fixed to the bottom of the wire hanging seat 535, and the wire hanging seat 535 is fixed to the bottom of the cutter seat 533 and avoids the cutter 534. The wire hanging column 536 is fixed to the bottom of the wire hanging seat 535, so that the position of the wire hanging column 536 is lower than the position of the welding head 532, and the position of the welding head 532 is lower than the position of the cutter 534. In this way, the welding head 532, the cutter 534 and the wire hanging column 536 are arranged in sequence from the inside to the outside, and there is a certain distance between the two, so that they will not interfere with each other.

[0032] Specifically, Figure 4 and Figure 5As shown, when working, the welding moving part 52 drives the welding assembly 53 to move, first let the wire hanging column 536 press the wire to move so that the wire is located at the welding position of the product, then the welding moving part 52 drives the welding assembly 53 to move forward, so that the welding head 532 is aligned with the welding position of the product and welds, and after welding is completed, the welding moving part 52 drives the welding assembly 53 to move back so that the cutter 534 is aligned with the redundant wire for cutting. In this process, when hanging the wire, the welding head 532 and the cutter 534 are located at the rear of the product, which will not affect the hanging process. And when welding, the cutter 534 and the wire hanging column 536 are located in front of the product, which will not affect the welding process. When cutting the wire, the cutter 534 is aligned with the wire of the product, and the product can be located between the spacing between the welding head 532 and the cutter 534 or the cutter 534 and the wire hanging column 536, and the cutting process will not be affected, so as to ensure that each component does not interfere with each other, and ensure that the product is smoothly processed and welded. This can ensure that the wire is mounted in place and does not change position during welding, which is beneficial to improving the quality of welding. In addition, the processing process is fully automated, which is beneficial to improving production efficiency and ensuring product consistency, thereby ensuring product production quality.

[0033] An automatic spot welding machine provided in this embodiment, such as Figure 6 As shown, the wire pulling mechanism 4 includes a wire pulling moving part 41 and a wire pulling assembly 42. The wire pulling moving part 41 is fixed on the mounting base 2. The wire pulling moving part 41 is also preferably in a relative sliding manner of a slider rail. The wire pulling assembly 42 is fixed on the wire pulling moving part 41 and moves with the wire pulling moving part 41. The wire pulling assembly 42 includes a wire pulling clamp seat 421, a wire pulling clamp 423 and a wire pulling pushing cylinder 422. The wire pulling clamp seat 421 is fixed on the wire pulling moving part 41. The wire pulling clamp seat 421 is provided with an air avoidance opening. The wire pulling pushing cylinder 422 is arranged below the air avoidance opening. The wire pulling clamp 423 is fixed on the pushing shaft of the wire pulling pushing cylinder 422 through the air avoidance opening and is located above the wire pulling clamp seat 421. When the wire-pushing cylinder 422 contracts, the wire-pushing clamp 423 and the wire-pushing clamp seat 421 engage with each other. When the wire needs to be clamped, the driving shaft of the wire-pushing cylinder 422 extends upward from the air-avoiding opening and drives the wire-pushing clamp 423 to move upward. When the wire is located between the wire-pushing clamp 423 and the wire-pushing clamp seat 421, the wire-pushing cylinder 422 retracts and drives the wire-pushing clamp 423 to move downward to clamp the wire backward, so that the wire is straightened and located at the spot welding position of the product, ensuring that the wire will not deviate during the spot welding process and ensuring the production quality of the product. Moreover, due to the existence of the air-avoiding opening, the wire-pushing clamp 423 and the wire-pushing clamp seat 421 will not interfere with each other during the whole process, ensuring the stability of the structure.

[0034] An automatic spot welding machine provided in this embodiment, such as Figure 7 As shown, the spot welding fixture 6 includes a fixture body 61, a pressing assembly 62 and an elastic pad 63. A clamping channel 64 is provided in the middle of the fixture body 61. The elastic pad 63 is fixed in the clamping channel 64. The clamping channel 64 provides a suitable installation space condition for the elastic pad 63. The elastic pad 63 carries the product to be spot welded, thereby limiting the product to be spot welded in the clamping channel 64, which is convenient for spot welding. The pressing assembly 62 includes a pressing seat 621 and a pressing rod 622. The pressing seat 621 is fixed to the side of the fixture body 61, and the pressing rod 622 is slidably connected to the pressing seat 621.

[0035] Specifically, first slide the pressing rod 622 outward along the pressing seat 621 to open, place the product to be spot welded on the elastic pad 63 of the clamping channel 64, and then push the pressing rod 622 to slide back to press the product, so that the product is located in the clamping channel 64 and compresses the elastic pad 63 downward. At this time, all sides of the product are restricted by the inner wall of the clamping channel 64, and no horizontal deflection occurs. Moreover, after the elastic pad 63 is compressed, it exerts an upward reaction force on the product, while the pressing rod 622 exerts a downward force on the product, so that the product can be firmly clamped to ensure that the product will not deviate in the up and down directions, and the elastic pad 63 is in flexible contact with the product, so that the product will not be damaged due to rigid pressure. When the spot welding is completed, push the pressing rod 622 outward to release the product, and then take out the product.

[0036] An automatic spot welding machine provided in this embodiment, such as Figure 7 As shown, the clamp body 61 is provided with a wire clamping plate 65 on the opposite side of the pressing seat 621, and the wire clamping plate 65 corresponds to the pressing seat 621. The pressing seat 621 and the two ends of the wire clamping plate 65 are correspondingly provided with wire clamping grooves 66, and the inner wall of the wire clamping groove 66 is provided with a rubber block, which has a certain elastic force and is conducive to clamping wires of different thicknesses.

[0037] An automatic spot welding machine provided in this embodiment, such as Figure 8As shown, the transmission mechanism 3 includes a transmission base 31, a transmission component 32 and two transfer components 33. The transmission component 32 is fixedly installed on the side of the transmission base 31. The two transfer components 33 are fixedly arranged on the transmission component 32 at intervals, and the spacing between the two transfer components 33 is equal to the spacing from the middle to the end of the transmission base 31, ensuring that when one of the transfer components 33 is located at the processing position in the middle of the transmission base 31, the other transfer component is located at the end of the transmission base 31, so that the material can be loaded while processing. The transmission component 32 drives the two transfer components 33 to move back and forth. The transmission component 32 rotates forward to drive the transfer component 33 to move forward. After the processing is completed, the transmission component 32 rotates in the reverse direction to drive the transfer component 33 to move back, and this cycle continues.

[0038] Specifically, the welding mechanism 5 is arranged in the middle of the transmission mechanism 3. In the initial state, one transfer assembly 33 is located in the middle of the transmission base 31, and the other transfer assembly 33 is located at the end of the transmission base 31. For the convenience of explanation, the initial state is that one transfer assembly 33 is located at the left end and the other transfer assembly 33 is located in the middle. When spot welding is performed, the product to be processed is placed on the transfer assembly 33 located at the left end, and then the transmission assembly 32 rotates forward to transfer the transfer assembly 33 to the position of the welding mechanism 5 in the middle of the transmission base 31. Since the two transfer components 33 are fixedly arranged on the transmission component 32 at intervals, when the transfer component 33 located at the left end of the transmission base 31 moves to the middle of the transmission base 31, the transfer component 33 located in the middle of the transmission base 31 in the initial state moves with the transmission component 32 to the right end of the transmission base 31. At this time, the processing mechanism processes the transfer component 33 in the middle, and the product to be processed can be placed on the transfer component 33 at the right end, so that the material can be loaded while the processing is being processed, saving the waiting time for loading. After the processing is completed, the transmission component 32 rotates in the opposite direction to move the transfer component 33 located in the middle that has been processed to the left to the left end, and the transfer component 33 located at the right end is also transferred to the middle for processing, and this cycle continues. The transmission mechanism 3 can ensure that when one of the transfer components 33 is located in the middle of the transmission component 32 for processing, the other transfer component 33 is located at the end for loading. This can save the time waiting for loading and there is no need to recover the clamp and put it back to the loading location for loading. This ensures that the equipment can carry out processing without stopping, greatly improving production efficiency.

[0039] An automatic spot welding machine provided in this embodiment, such as Fig. 9As shown, the transfer assembly 33 includes a transfer base 331, a rotating cylinder 332 and a carrying plate 333. The transfer base 331 is fixed on the conveying assembly 32 to move back and forth with the conveying assembly 32. The rotating cylinder 332 is fixed on the conveying base. The carrying plate 333 is arranged on the rotating cylinder 332. The spot welding fixture 6 is placed on the carrying plate 333. The spot welding fixture 6 clamps the product for processing. When one side of the product is processed, the rotating cylinder 332 drives the carrying plate 333 to rotate so that the other side of the product is aligned with the processing position, so as to facilitate comprehensive processing of the product.

[0040] An automatic spot welding machine provided in this embodiment, such as Figure 8 As shown, it also includes a positioning assembly 7, which includes a positioning mounting seat 71, a positioning push cylinder 73, a positioning rod 74 and a positioning plate 72. The positioning mounting seat 71 is fixed to the side of the transmission base 31, the positioning push cylinder 73 is vertically fixed to the positioning mounting seat 71, the positioning rod 74 is fixed to the driving shaft of the positioning push cylinder 73, and the positioning plate 72 is fixed to the bottom of the transfer assembly 33. The positioning plate 72 is provided with a position that matches the positioning rod 74. When positioning, the positioning push cylinder 73 pushes the positioning rod 74 to move upward and clamps the position of the positioning plate 72 at the bottom of the transfer assembly 33, so that the transfer assembly 33 no longer moves. At this time, spot welding the product can ensure that the position of the transfer assembly 33 remains relatively fixed during the spot welding process, effectively avoiding the problem of product quality defects caused by the position change of the transfer assembly 33.

[0041] The present invention is further described above with the aid of specific embodiments. However, it should be understood that the specific description here should not be construed as limiting the essence and scope of the present invention.
