[0045] like Figure 1-Figure 6As shown, this embodiment provides a welding device, which includes a first conveying module 100, a second conveying module 200 and a welding module 300. The first conveying module 100 is used to convey a first part 10, and a plurality of first parts 10 form a material belt. The first conveying module 100 is provided with a welding area 110; the second conveying module 200 is used to convey a carrying module 400, and the carrying module 400 is used to carry a plurality of second parts 20. The second conveying module 200 passes under the welding area 110; the welding module 300 is arranged in the welding area 110, and includes a welding head 310 and a welding lifting drive assembly 320. The welding head 310 is used to connect the plurality of second parts 20 with the first part 10. Welding, the welding lifting drive assembly 320 is used to drive the welding head 310 to move in the vertical direction, so that the welding head 310 is selectively placed in the initial position, the welding pre-positioning position and the first welding position, the welding pre-positioning position is higher than the initial position, and the first welding position is higher than the welding pre-positioning position; the carrying module 400 is provided with a carrying platform 410 and a carrying lifting drive assembly 420, the carrying platform 410 is used to carry the second part 20, the carrying lifting drive assembly 420 is used to drive the carrying platform 410 to move in the vertical direction, so that the carrying platform 410 is selectively placed in the conveying position, the carrying pre-positioning position and the second welding position, the carrying pre-positioning position is higher than the conveying position, and the second welding position is higher than the pre-positioning position.

[0046] The first conveying module 100 and the second conveying module 200 are provided to convey the first part 10 and the second part 20 respectively, wherein the first part 10 forms a material strip, and the second part 20 is provided in plurality, so that the welding between the plurality of first parts 10 and the corresponding second parts 20 can be realized by one welding. During welding, the first conveying module 100 and the second conveying module 200 convey the first part 10 and the second part 20 to the welding area 110 respectively; before positioning, the welding head 310 is in the highest welding position, and the carrier 410 is in the lowest conveying position; positioning begins, first the carrier 410 moves up to the bearing pre-positioning position to realize the positioning between the carrier 410 and the material strip; then the welding head 310 descends to the welding pre-positioning position to assist in positioning the material strip and the carrier 410; next the carrier 410 moves up to the second welding position to position the second part 20 and the first part 10; finally the welding head 310 moves down to the first welding position to complete the welding. The above positioning process does not need to position the first part 10 and the second part 20 separately, which reduces the number of positioning times and ensures positioning accuracy. At the same time, it simplifies the structure and improves welding efficiency. By directly completing the relative positioning of the first part 10 and the second part 20 in the welding area 110, the positioning is more convenient and accurate.

[0047] Preferably, the supporting module 400 is also provided with a clamping assembly for clamping the material strip and the second part 20 after being moved to the second welding position on the supporting platform 410, so as to ensure the relative fixation of the position between the first part 10 and the second part 20 after positioning, reduce relative displacement, and thereby improve the accuracy of welding.

[0048] Exemplarily, a welding positioning piece 411 is provided on the carrier platform 410, and a welding positioning hole is provided on the first part 10. When the carrier platform 410 moves from the conveying position to the carrying pre-positioning position, the welding positioning piece 411 on the carrier platform 410 can be placed in the welding positioning hole, thereby realizing the positioning between the carrier platform 410 and the material strip.

[0049] Specifically, the second conveying module 200 is also provided with a pre-pressing unit 210, which is used to pre-press the second part 20 before conveying the first part 10 to the welding area 110. The second part 20 after pre-pressing is placed on the carrier 410 in the horizontal direction to facilitate subsequent positioning with the first part 10. Optionally, the pre-pressing unit 210 is provided with a pre-pressing head 211 and a pre-pressing lifting assembly 212, and the pre-pressing lifting assembly 212 is used to drive the pre-pressing head 211 to rise and fall, and the pre-pressing head 211 is used to cooperate with the second part 20 to achieve the pressing of the second part 20. It can be understood that the pre-pressing head 211 is adapted to the shape of the second part 20, and corresponds to the number of the second parts 20 on the carrier 410 one by one, which can reduce the damage to the second part 20 while ensuring the reliability of pre-pressing.

[0050] Optionally, the second conveying module 200 is provided with two parallel and spaced conveying belts 220, each of which can be used to convey the carrier module 400, so as to improve the conveying efficiency of the second part 20, thereby improving the welding efficiency. Exemplarily, the conveying directions of the first conveying module 100 and the second conveying module 200 are perpendicular to each other, so as to facilitate the arrangement of modules on both sides of the first conveying module 100 and the second conveying module 200, so that the layout between the modules is more reasonable and the interference between the modules is reduced.

[0051] Correspondingly, the pre-pressing unit 210 is also provided with a pre-pressing driving assembly 213, which is used to drive the pre-pressing lifting assembly 212 and the pre-pressing head 211 to reciprocate above the two conveyor belts 220; in addition, the welding module 300 is provided with a welding driving assembly, which is used to drive the welding lifting driving assembly 320 and the welding head 310 to reciprocate above the two conveyor belts 220. That is, both the pre-pressing head 211 and the welding head 310 are provided with one, and both can reciprocate between the two conveyor belts 220, which is conducive to simplifying the structure of the welding equipment. During operation, when the welding module 300 is welding the second part 20 on a conveyor belt 220, the pre-pressing unit 210 can pre-press the carrying module 400 on another conveyor belt 220, and then convey it to the welding area 110 after pre-pressing; after the welding head 310 completes welding, the welding drive assembly can drive the welding head 310 to move to the corresponding other conveyor belt 220 to continue welding, thereby effectively reducing the waiting time of the welding head 310 and improving the welding efficiency.

[0052] In this embodiment, the second conveying module 200 further includes a second feeding unit 230, which is used to supply the second part 20 to the carrier module 400 placed on the conveyor belt 220. Specifically, the second feeding unit 230 includes a feeding robot 231 and at least two feeding bins 232, the feeding bins 232 are used to place the second part 20, and the feeding robot 231 can grab the second part 20 in any feeding bin 232 and place it on the carrier platform 410 of the carrier module 400 on the conveyor belt 220.

[0053] Optionally, at least two feeding bins 232 can carry different types of second parts 20, so as to facilitate welding at least two types of second parts 20 on the first part 10. It is worth noting that each type of second part 20 can also be provided with a plurality of parts, and those skilled in the art can set them according to the required products, which is not specifically limited here. It is understandable that the feeding bin 232, the feeding robot arm 231 and the carrying platform 410 are all adapted to the shape and quantity of the second parts 20 to be welded.

[0054] Preferably, the feeding bin 232 is provided with a clamping claw for clamping the second part 20 in the bin. The second feeding unit 230 is also provided with an adjustment component 233. The second part 20 clamped by the clamping claw can be placed on the suction nozzle of the adjustment component 233. The adjustment component 233 can rotate the suction nozzle. The feeding robot arm 231 grabs the second part 20 adjusted by the adjustment component 233 and places it on the carrier 410. Each feeding bin 232 is correspondingly provided with an adjustment component 233, and one feeding robot arm 231 corresponds to two adjustment components 233.

A positioning drive hole 11 is provided on the first part 10, and the convex tooth 1211 can cooperate with the positioning drive hole 11 when the positioning drive wheel 121 rotates. It can be understood that the positioning drive wheel 121 of the positioning unit 120 can not only realize the positioning of the material belt, but also realize the conveyance of the material belt.

[0056] Preferably, the first conveying module 100 is also provided with an initial positioning member 130, and the first part 10 is provided with an initial positioning hole 12, and the initial positioning member 130 can be placed in the initial positioning hole 12; specifically, the first conveying module 100 also includes a first feeding unit 140, and the first feeding unit 140 includes a slideway 141 arranged obliquely downward. The loading process of the first part 10 is as follows: the material belt descends from the slideway 141 by gravity, so that the initial positioning member 130 can be inserted into the initial positioning hole 12; after the initial positioning member 130 is inserted into the initial positioning hole 12, the positioning lifting assembly 122 of the positioning unit 120 drives the positioning drive wheel 121 to descend, so that the protruding tooth 1211 is placed in the positioning drive hole 11, and the positioning of the material belt is completed; when the positioning drive wheel 121 rotates, the material belt is conveyed toward the welding area 110.

[0057] In this embodiment, the welding equipment is also provided with a detection module 500, which is arranged downstream of the first conveying module 100, and is used to detect the welded products; further, the welding equipment is also provided with a finished product module 600, and the finished product module 600 includes a finished product handling robot arm 610 and a finished product warehouse 620, and the finished product handling robot arm 610 is used to transport the welded and tested qualified products to the finished product warehouse 620, and the finished product warehouse 620 is used to hold qualified finished products.

It is worth noting that the various driving parts of the welding equipment can be implemented by a cylinder or a kk module, which will not be repeated here.

[0058] This embodiment further discloses a welding method, using the welding equipment as described in any of the above schemes, the welding method comprises:

[0059] The first conveying module 100 conveys the first part 10 forming the material strip to the welding area 110, and is positioned by the initial positioning member 130 before conveying. During conveying, a positioning driving wheel 121 is used to achieve positioning while conveying. The second conveying module 200 conveys a plurality of second parts 20 placed on the carrier 410 to the welding position. Before reaching the welding position, the second parts 20 are pre-pressed by the pre-pressing head 211 to facilitate the positioning of the welding area 110.

[0060] The carrying platform 410 rises from the conveying position to the carrying pre-positioning position to achieve positioning between the carrying platform 410 and the material strip; the welding head 310 descends from the initial position to the welding pre-positioning position to assist in positioning the material strip and the carrying platform 410; the carrying platform 410 rises from the carrying pre-positioning position to the first welding position to position the second part 20 and the first part 10; the welding head 310 descends from the welding pre-positioning position to the second welding position for welding.
