[0030] Reference Figures 1 to 3 The present invention discloses a resistor assembly machine, comprising a frame 100, a resistor welding device 400 and a resistor shell insertion mechanism 500 arranged on the frame 100, a first rotating disk 110 is arranged on the frame 100, a plurality of first carriers 200 are arranged on the first rotating disk 110, and a first receiving groove 210 for receiving the shell and two second receiving grooves 220 for receiving the resistor are arranged on the first carrier 200; see Figure 4 and Figure 5The resistor assembly machine also includes a resistor shaping device 300, which includes a second turntable 310 and a first liftable pressing head 320. The second turntable 310 and the first pressing head 320 are both arranged on the frame 100. The second turntable 310 is provided with a plurality of second carriers 330, and the second carriers 330 are provided with a plurality of third accommodating grooves 331 for accommodating resistors. The second carrier 330 is provided with a first avoidance hole 332 next to the third accommodating groove 331. The pins of the resistor extend into the first avoidance hole 332, and the first pressing head 320 can extend into the first avoidance hole 332 and bend the pins; the resistor welding device 400 is used to weld the resistors in the two second accommodating grooves 220 together; the resistor shell insertion mechanism 500 is used to install the two welded resistors on the shell.

[0031] The first pressing head 320 presses down the pin of the resistor to achieve bending of the pin, thereby completing the shaping of the resistor; the resistor welding device 400 welds the pins of the two resistors together; the resistor shell insertion mechanism 500 installs or assembles the two welded resistors on the shell, and can quickly complete the shaping, welding and assembly of the two resistors on the shell, thereby improving the processing quality and speed, replacing manual work, liberating labor, and reducing labor production costs.

[0032] In some embodiments of the present invention, the first carrier 200 is provided with a second avoidance hole 230 in the area between the two second receiving grooves 220, and the two resistors can be placed in the two second receiving grooves 220 and the pins of the two resistors are placed in the second avoidance hole 230. The two resistors are placed in the two second receiving grooves 220 respectively. At this time, one pin of one resistor and one pin of the other resistor meet in the second avoidance hole 230. The first carrier 200 plays the role of carrying and limiting the fixed resistors. Because the spacing between the two second avoidance holes 230 is constant, the spacing between the two resistors and the shape of the pins can be effectively controlled, so that the shape of the welding point meets the requirements, ensuring the welding quality of the resistors and the quality level of each welding is stable. The pins are placed in the second avoidance hole 230 so that the pins are exposed, so that the resistor welding device 400 can weld the two pins together.

[0033] See also Figures 6 to 8The resistance welding device 400 includes a welding machine (not shown in the figure), an upper electrode head 410 and a lower electrode head 420, both of which are electrically connected to the welding machine, the upper electrode head 410 is arranged above the second avoidance hole 230 and can be raised and lowered, the lower electrode head 420 is arranged below the second avoidance hole 230 and can be raised and lowered, and both the upper electrode head 410 and the lower electrode head 420 can be extended into the second avoidance hole 230 and clamp the pins. When the upper electrode head 410 and the lower electrode head 420 extend into the second avoidance hole 230 and clamp the two pins, the welding machine passes the upper electrode head 410 and the lower electrode head 420, and heats the contact point of the two pins for welding, and finally fixes the two pins together. After the two pins are connected together, the upper electrode head 410 and the lower electrode head 420 are moved out of the second avoidance hole 230, so that the first turntable 110 can carry the first carrier 200 to rotate.

[0034] The first turntable 110 rotates with the first carrier 200, that is, it moves with the resistor. When the first first carrier 200 carrying the resistor moves to the bottom of the upper electrode head 410, the upper electrode head 410 and the lower electrode head 420 clamp and weld the pins of the resistor together. After the pin welding is completed, the first turntable 110 continues to rotate to remove the first first carrier 200 from the bottom of the upper electrode head 410, so as to facilitate the removal of the welded resistor from the first first carrier 200 and to put the resistor to be welded back into the first first carrier 200; when the first first carrier 200 is removed from the bottom of the upper electrode head 410, another first carrier 200 carrying the resistor to be welded moves to the bottom of the upper electrode head 200, and the upper electrode head 410 and the lower electrode head 420 can weld the next pair of resistors, and so on, continuously welding new resistors into a pair, thereby improving the efficiency of welding resistors. The number of first carriers 200 and the intervals between first carriers 200 can be set according to actual needs. The first carriers 200 are evenly distributed on the upper surface of the first turntable 110, and all first carriers 200 are arranged with the central axis of the turntable as the center of the circle.

[0035] In some embodiments of the present invention, the resistance welding device 400 further includes a first support frame 430 and a second support frame 440 disposed on the frame 100, the lower electrode head 420 and the upper electrode head 410 are respectively disposed on the first support frame 430 and the second support frame 440 in a manner that they can be lifted and lowered, and a pressing plate 450 is disposed on the first support frame 430, one end of which can extend above the second receiving groove 220 and press the resistor into the second receiving groove 220. The first support frame 430 plays the role of supporting the lower electrode head 420, and the lower electrode head 420 performs an ascending or descending movement on the first support frame 430; the second support frame 440 plays the role of supporting the upper electrode head 410, and the upper electrode head 410 performs an ascending or descending movement on the second support frame 440.

[0036] In some embodiments of the present invention, a linear drive mechanism 460 is provided on the first support frame 430, the middle section of the pressing plate 450 and the first support frame 430 are hinged via a hinge shaft, the output end of the linear drive mechanism 460 is hinged to the other end of the pressing plate 450 to drive the pressing plate 450 to rotate around the hinge shaft and one end of the pressing plate 450 extends to press the resistor down. The pressing plate 450 here is similar to a lever, and the linear drive mechanism 460 drives the other end of the pressing plate 450 to rotate the pressing plate 450 around the hinge shaft, thereby causing one end of the pressing plate 450 to press or release the resistor. It is foreseeable that the linear drive mechanism 460 is a cylinder, the cylinder body is hinged to the first support frame 430, and the piston rod of the cylinder is hinged to one end of the pressing plate 450.

[0037] In some embodiments of the present invention, an elastic restoring member is connected between the other end of the pressing plate 450 and the first support frame 430. When the pressing plate 450 is not needed to press the resistor, the linear drive mechanism 460 no longer applies force to the other end of the pressing plate 450, and the elastic restoring member applies force to the other end of the pressing plate 450, so that one end of the pressing plate 450 is tilted, that is, one end of the pressing plate 450 is away from the resistor or the first carrier 200, and the initial state of the pressing plate 450 is that one end of the pressing plate 450 is away from the resistor or the first carrier 200. It can be understood that the elastic restoring member is a tension spring, and the two ends of the tension spring are respectively connected to the first support frame 430 and the other end of the pressing plate 450.

[0038] In some embodiments of the present invention, cooling water channels (not shown in the figure) are provided in the upper electrode head 410 and the lower electrode head 420. When the upper electrode head 410 and the lower electrode head 420 are electrically heated and welded together, the upper electrode head 410 and the lower electrode head 420 will be heated up. Passing cooling water into the cooling water channel can cool down the upper electrode head 410 and the lower electrode head 420, avoid the upper electrode head 410 and the lower electrode head 420 from being too high in temperature, and achieve the function of protecting the upper electrode head 410 and the lower electrode head 420. Furthermore, a first water inlet joint and a first water outlet joint are provided on the side wall of the upper electrode head 410, and the first water inlet joint and the first water outlet joint are respectively connected to the water inlet end and the water outlet end of the cooling water channel; similarly, a second water inlet joint and a second water outlet joint are provided on the side wall of the lower electrode head 420, which facilitates the layout and connection of the cooling water pipeline.

[0039] In some embodiments of the present invention, the lower surface of the upper electrode head 410 and the upper surface of the lower electrode head 420 are both provided with a limiting groove 600 for limiting the pin. When the upper electrode head 410 and the lower electrode head 420 are close to each other to clamp the pin, the pin will slide into the limiting groove 600, thereby preventing the pin from being offset, ensuring that the two pins meet together and the shapes of each pair of pins that meet together are consistent, thereby ensuring that the shape of the welding point meets the requirements and the quality of the welding is guaranteed.

[0040] In some embodiments of the present invention, the first carrier 200 is provided with an avoidance groove 240 connected to the second receiving groove 220, and the clamp for clamping and carrying the resistor can extend into the avoidance groove 240. The resistor can be clamped by the clamp and placed into the second receiving groove 220 or the resistor can be moved out of the second receiving groove 220. The second receiving groove 220 is provided so that the clamp can extend into the second receiving groove 220, so that the resistor can be smoothly placed into the second receiving groove 220 or the resistor can be moved out of the second receiving groove 220, thereby achieving accurate positioning of the resistor and avoiding interference between the clamp and the first carrier 200.

[0041] See also Fig. 9 The resistor shell insertion mechanism 500 includes a first horizontal driving mechanism 510, a first lifting driving mechanism 520 and an electromagnet 530. The first horizontal driving mechanism 510 is arranged on the frame 100 and the central axis of the first horizontal driving mechanism 510 intersects with the central axis of the first turntable 110. The first lifting driving mechanism 520 is arranged on the output end of the first horizontal driving mechanism 510. The output end of the first lifting driving mechanism 520 faces downward and is connected to the electromagnet 530. The electromagnet 530 is located above the first carrier 200. Initially, the electromagnet 530 is located above the second receiving groove 220, the first lifting drive mechanism 520 drives the electromagnet 530 to descend and the electromagnet 530 is energized, and the electromagnet 530 absorbs the two resistors that have been welded together in the second receiving groove 220, and then the first lifting drive mechanism 520 drives the electromagnet 530 to rise, and the first horizontal drive mechanism 510 drives the first lifting drive mechanism 520 and the electromagnet 530 to move in the horizontal direction, so that the electromagnet 530 moves to the top of the first receiving groove 210, and then the first lifting drive mechanism 520 drives the electromagnet 530 to descend and the electromagnet 530 is powered off, and the first lifting drive mechanism 520 places the two resistors that have been welded together in the installation position of the shell in the first receiving groove 210.

[0042] In some embodiments of the present invention, the resistor shaping device 300 further includes a second pressing head 340, which is disposed above the third receiving groove 331 and can be raised and lowered, and the second pressing head 340 can press the resistor tightly into the third receiving groove 331. When the first pressing head 320 presses down to bend the pin, the second pressing head 340 simultaneously presses down and presses the resistor tightly into the third receiving groove 331, so as to avoid the resistor from shifting and causing the pin to be bent and unqualified. Specifically, a fifth lifting drive mechanism is disposed on the frame 100, and the first pressing head 320 and the second pressing head 340 are both disposed on the fifth lifting drive mechanism. The fifth lifting drive mechanism is a cylinder.

[0043] It can be understood that the first support frame 430 is provided with a second horizontal driving mechanism 490, and the lower electrode head 420 is connected to the output end of the second horizontal driving mechanism 490. The second horizontal driving mechanism 490 can drive the lower electrode head 420 to move in the horizontal direction, so as to adjust the position of the lower electrode head 420 relative to the upper electrode head 410, and ensure that the lower electrode head 420 and the upper electrode head 410 are in positive correspondence so as to realize the positioning and clamping of the pin. The first horizontal driving mechanism 510, the first lifting driving mechanism 520 and the second horizontal driving mechanism 490 can all be cylinders.

[0044] It should be understood that the first support frame 430 and the second support frame 440 are respectively provided with a third lifting drive mechanism 470 and a fourth lifting drive mechanism 480, and the lower electrode head 420 and the upper electrode head 410 are respectively connected to the output end of the third lifting drive mechanism 470 and the output end of the fourth lifting drive mechanism 480. The third lifting drive mechanism 470 and the fourth lifting drive mechanism 480 respectively drive the lower electrode head 420 and the upper electrode head 410 to rise or fall. The third lifting drive mechanism 470 and the fourth lifting drive mechanism 480 are both cylinders.
