[0025] The embodiments of the present application will be further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0027] The specific operation is as follows: first, the metal plate 3 is placed on the surface of the tray 2, and the bolt is inserted through the hole on the side of the metal plate 3 to stably install it on the surface of the tray 2, at this time the PIN needle 4 is placed in the needle body positioning groove 5, and the pin support 7 penetrates the hollow part of the metal plate 3, then the pins at both ends of the resistance body 8 are placed in the pin support 7 after being pretreated to keep them consistent, at this time the top of the pin support 7 supports and limits the pins of the resistance body 8, so that the resistance body 8 is accurately positioned to the specified position and the pins are also located at the specified position on the surface of the metal plate 3;

[0028] Then cover the resistance positioning plate 9 so that its two sides are sleeved to the outer wall of the positioning pin 6, and the resistance positioning plate 9 is attached to the surface of the profiling positioning plate 1, at this time each resistance body 8 is located in the square hole 10;

[0029] Then cover the resistance cover plate 11 so that its two sides are sleeved to the outer wall of the positioning pin 6, and the bottom of the resistance cover plate 11 is attached to the upper surface of the resistance positioning plate 9, at this time the welding hole 12 is located directly above the contact part of the pin of the resistance body 8 and the surface of the metal plate 3, and after the profiling positioning plate 1, the resistance positioning plate 9 and the resistance cover plate 11 are attached to each other, the nut is tightened on the top of the positioning pin 6 to prevent the three from loosening;

[0030] When welding, only the welding head needs to be inserted into the welding hole 12 to accurately weld the pin of the resistance body 8 to the specified position on the surface of the metal plate 3, after welding, the resistance cover plate 11, the resistance positioning plate 9 are taken off in turn, and the welded metal plate 3 can be taken out;

[0031] Based on the above-mentioned parts, the present invention utilizes the contoured positioning plate 1 and the resistor positioning plate 9 in conjunction with the resistor cover plate 11 to limit the installation of the metal plate 3, and enables the pin support 7 to accurately support the resistor body 8, so that the resistor body 8 is accurately positioned to the specified position, and the pins that remain consistent after pre-treatment can accurately contact the specified position on the surface of the metal plate 3 through the pin support 7, and then cooperate with the welding hole 12 to insert the welding head into it to accurately weld the pins to the specified position on the surface of the metal plate 3, thereby realizing batch resistance welding and effectively improving welding efficiency and yield rate.

[0032] like Figures 1-6 As shown, a lifting clamping assembly 13 is provided around the profiling positioning plate 1, and the lifting clamping assembly 13 includes a transmission column 1301 and a lifting sliding support 1302. The bottom of the transmission column 1301 is fixed with a lifting sliding support 1302, and the lifting clamping assembly 13 also includes an elastic airbag 1303. The bottom of the lifting sliding support 1302 is connected with an elastic airbag 1303. The transmission column 1301 and the lifting sliding support 1302 are elastically connected to the profiling positioning plate 1 through the elastic airbag 1303, and the lifting sliding support 1302 penetrates to the inner side of the profiling positioning plate 1, and the end of the lifting sliding support 1302 is connected to the bottom of the tray 2. The elastic airbag 1303 is connected to the needle clamping block 1304 through a catheter, and the needle clamping block 1304 is provided on both sides of the needle positioning groove 5;

[0033] The specific operation is as follows: when the resistor positioning plate 9 is attached to the surface of the contoured positioning plate 1, the protruding transmission column 1301 is lowered and retracted into the contoured positioning plate 1 under the downward pressure of the resistor positioning plate 9. At this time, the lifting sliding support 1302 is lowered accordingly, and the lifting sliding support 1302 will also lower the tray 2 until the tray 2 is lowered to the lowest point with the lifting sliding support 1302. At this time, the resistor body 8 is located directly below the square hole 10 without being excessively protruding;

[0034] When the lifting sliding support 1302 descends, the elastic airbag 1303 is compressed. At this time, the gas inside the elastic airbag 1303 pushes the needle clamping blocks 1304 on both sides of the needle positioning groove 5 to extend along the conduit, so that the needle clamping blocks 1304 cooperate with the needle positioning groove 5 to stably clamp the PIN needle 4. When the pin of the resistor body 8 needs to be accurately connected to the PIN pin 4, the PIN pin 4 can be prevented from being deformed when the entire carrier moves or turns over, thereby ensuring that the pin of the resistor body 8 can be accurately positioned on the PIN pin 4.

[0035] And after the welding, when the resistance positioning plate 9 is removed, the spring in the elastic air bag 1303 is automatically reset, so that the lifting sliding support 1302 and the transmission column 1301 are automatically lifted, and the tray 2 carrying the welded metal plate 3 is lifted, so that the metal plate 3 is taken out;

[0036] Based on the above description, the resistance positioning plate 9 and the profiling positioning plate 1 are matched, the tray 2 carrying the metal plate 3 is automatically lowered to prevent the resistance body 8 from protruding too much, and when the elastic air bag 1303 is compressed, the gas inside is circulated to drive the needle clamping block 1304 to extend to clamp the PIN pin 4, thereby avoiding the PIN pin 4 from being deformed when the whole carrier moves and turns, so as to ensure that the pins of the resistance body 8 can be accurately positioned on the PIN pin 4, and after the resistance positioning plate 9 and the profiling positioning plate 1 are separated, the elastic air bag 1303 is restored, so that the tray 2 carrying the welded metal plate 3 is automatically lifted, so that the metal plate 3 is taken out.

[0037] As shown in Figures 1-6 The resistance positioning plate 9 is internally provided with resistance clamping assemblies 14 on both sides, the resistance clamping assemblies 14 include air bag pressing plates 1401 and telescopic rubber blocks 1402, the telescopic rubber blocks 1402 are located on both sides of the square hole 10, and the telescopic rubber blocks 1402 are in two groups.

[0038] Specifically, when the resistance positioning plate 9 is attached to the surface of the profiling positioning plate 1, the air bag pressing plates 1401 on both sides of the bottom of the resistance positioning plate 9 are also forced to retract into the resistance positioning plate 9, so that the gas in the air bag inside the resistance positioning plate 9 fills the telescopic rubber blocks 1402, so that the telescopic rubber blocks 1402 extend to resist the resistance body 8 on both sides, thereby stably clamping the resistance body 8, thereby cooperating with the pin support 7 to limit and position the pin part of the resistance body 8, thereby avoiding the positioning failure and deviation when the carrier carrying the accurately positioned metal plate 3 and the resistance body 8 moves and turns;

[0039] Based on the above description, the resistance positioning plate 9 and the profiling positioning plate 1 are matched, the air bag pressing plates 1401 are forced to retract into the resistance positioning plate 9, so that the gas inside the air bag is driven to extend the telescopic rubber blocks 1402 to clamp on both sides of the resistance body 8, thereby cooperating with the pin support 7 to limit and position the pin part of the resistance body 8, and the whole resistance body 8 is clamped by multiple points, so as to avoid the resistance body 8 from falling off and deviating during the movement and turning of the carrier carrying the accurately positioned metal plate 3 and the resistance body 8.

[0040] In summary, the positioning accurate welding positioning carrier, in use, first put the metal plate 3 on the tray 2 surface, and use the bolt to pass through the hole position of the metal plate 3 side to firmly install it on the tray 2 surface, at this time the PIN needle 4 is placed in the needle body positioning groove 5, and the pin support 7 passes through the hollow part of the metal plate 3, and then the pins at both ends of the resistance body 8 are put into the pin support 7 after pretreatment, at this time the pin support 7 supports and limits the pins of the resistance body 8, so that the resistance body 8 is accurately positioned to the specified position and the pins are also located at the specified position of the metal plate 3 surface;

[0041] Then cover the resistance positioning plate 9, make its both sides set to the outer wall of the positioning pin 6, and the resistance positioning plate 9 is attached to the surface of the profiling positioning plate 1, at this time each resistance body 8 is located in the square hole 10;

[0042] Wherein, when the resistance positioning plate 9 is attached to the surface of the profiling positioning plate 1, the convex transmission column 1301 is lowered and retracted into the profiling positioning plate 1 under the pressure of the resistance positioning plate 9, at this time the lifting sliding support 1302 is lowered, and the lifting sliding support 1302 is lowered with the tray 2, until the tray 2 is lowered to the lowest part with the lifting sliding support 1302, at this time the resistance body 8 is located just below the square hole 10 without excessive convexity;

[0043] When the lifting sliding support 1302 is lowered, the elastic air bag 1303 is compressed under force, at this time the gas in the elastic air bag 1303 pushes the needle body clamping block 1304 on both sides of the needle body positioning groove 5 to extend, so that the needle body clamping block 1304 cooperates with the needle body positioning groove 5 to stably clamp the PIN needle 4, so that when the pins of the resistance body 8 need to be accurately connected with the PIN needle 4 part, the PIN needle 4 can not be deformed when the whole carrier moves and turns, so as to ensure that the pins of the resistance body 8 can be accurately positioned to the PIN needle 4 part;

[0044] When the resistance positioning plate 9 is attached to the surface of the profiling positioning plate 1, the air bag pressing plate 1401 on both sides of the bottom of the resistance positioning plate 9 will also be retracted into the resistance positioning plate 9 under force, so that the gas in the air bag in the resistance positioning plate 9 fills the position where the telescopic rubber block 1402 is located along the conduit, so that the telescopic rubber block 1402 extends to abut against the resistance body 8 on both sides, thereby stably clamping the resistance body 8, thereby cooperating with the pin support 7 to limit and position the pin part of the resistance body 8, thereby avoiding the positioning failure and deviation when the carrier carries the accurately positioned metal plate 3 and resistance body 8 moves and turns;

[0045] Then cover the resistance cover plate 11, make its both sides set to the outer wall of the positioning pin 6, and the resistance cover plate 11 bottom is attached to the upper surface of the resistance positioning plate 9, at this time the welding hole 12 is located just above the contact part of the pins of the resistance body 8 and the metal plate 3 surface;

[0046] In the welding, only the welding head is inserted into the welding hole 12, the pin of the resistance body 8 can be precisely welded to the specified part of the surface of the metal plate 3, after the welding is completed, the resistance cover plate 11 and the resistance positioning plate 9 are taken off in turn, and then the welded metal plate 3 can be taken out;

[0047] When the resistance positioning plate 9 is taken off, the spring in the elastic air bag 1303 is automatically reset, so that the lifting sliding support 1302 and the transmission column 1301 are automatically lifted, and at the same time, the tray 2 carrying the welded metal plate 3 is lifted, so as to take out the metal plate 3.
