[0037] An automatic feeding welding device according to an embodiment of the utility model is described below in conjunction with the accompanying drawings.

[0038] Reference Figure 1 An automatic feeding and welding device according to an embodiment of the utility model comprises a conveying mechanism, a punching mechanism, a material moving mechanism and a welding mechanism.

[0039] Among them, the conveying mechanism includes a first conveying component 100 and a second conveying component 110. The first conveying component 100 is used to convey the first material belt 120 after stamping, and the first material belt 120 forms a first stamping part 130. The first conveying component 100 is used to convey the second material belt 140 after stamping, and the second material belt 140 forms a second stamping part 150.

[0040] Reference Fig. 9 , Fig. 9 Schematic diagram of the structure of the first material strip 120 and the second material strip 140.

[0041] Specifically, refer to Figure 2 The first conveying assembly 100 includes a material trough for accommodating the first material belt 120, a pull pin for pulling the first material belt 120 to move, a first cylinder for driving the pull pin to rise and fall, and a second cylinder for driving the first cylinder to move horizontally. The first material belt 120 is provided with a through hole adapted for the pull pin. Therefore, the first cylinder drives the pull pin to descend, and the pull pin is inserted into the through hole of the first material belt 120. The second cylinder is used to drive the first cylinder to move horizontally, thereby pulling the first material belt 120 forward for transportation, thereby ensuring accurate transportation of the first material belt 120.

[0042] The first material strip 120 may be a coiled material, which is conveyed under the traction of the first conveying assembly 100 , or may be formed by a punch press and then conveyed forward via the first conveying assembly 100 .

[0043] It should be noted that the conveying structure of the second conveying assembly 110 is similar to the first conveying structure, and will not be described again.

[0044] The punching mechanism includes an upper cutting die 160 and a lower cutting die 170 arranged in the conveying direction of the first material strip 120 . The upper cutting die 160 and the lower cutting die 170 can cut the first stamping part 130 from the first material strip 120 when the upper cutting die 160 and the lower cutting die 170 are combined.

[0045] In some embodiments of the present invention, referring to Figure 7 The upper cutting die 160 is provided with a cutting channel 210 which passes through from top to bottom, and the lower cutting die 170 is provided with a punch 220 and a first power member which drives the punch 220 to rise and fall. The cutting channel 210 accommodates the punch 220 to pass through, and the punch 220 punches the first stamping part 130 upward so that the first stamping part 130 enters the cutting channel 210.

[0046] Specifically, a motor can be used as the power, and the motor drives the lower cutting die 170 to rise and fall through a crank slider mechanism to complete the clamping action of the upper cutting die 160 and the lower cutting die 170. Of course, a cylinder or an oil cylinder can also be used to drive the lower cutting die 170 to rise and fall.

[0047] Since the lower cutting die 170 can move up and down, the upper cutting die 160 can be set to a fixed structure. Therefore, the upper cutting die 160 can be arranged with a plurality of cutting channels 210, and ample space can be formed above the upper cutting die 160 to facilitate the material moving mechanism to enter the cutting channel 210 to extract the first stamping part 130.

[0048] During punching, driven by the first power member, the lower cutting die 170 drives the punch 220 to punch the first stamping part 130 upwards. The punch 220 cuts out the first stamping part 130, allowing the first stamping part 130 to enter the cutting channel 210, where the first stamping part 130 waits for extraction.

[0049] In addition, in order to improve production efficiency, a plurality of punches 220 may be provided, and the number of cutting channels 210 corresponds to the number of the punches 220 , so that a plurality of first stamping parts 130 can be punched out in one die closing.

[0050] In some embodiments of the present invention, referring to Figure 2 A material seat 230 is provided at the bottom of the upper cutting die 160 , and the material seat 230 is provided with a first limiting groove 240 . The first limiting groove 240 accommodates the first material strip 120 to pass through, so that the first stamping part 130 passes through the bottom of the cutting channel 210 .

[0051] Therefore, under the guidance of the first limiting groove 240 , the first stamping part 130 can accurately pass through the cutting channel 210 , and the punch 220 can accurately cut off the first stamping part 130 .

[0052] The material moving mechanism includes a material picking component and a moving component for driving the material picking component to move. The material picking component can clamp the first stamping part 130 and stack the first stamping part 130 on the second stamping part 150 .

[0053] In a further embodiment of the present invention, referring to Figure 3 The moving component is a PPU transplanting robot 280 , and the PPU transplanting robot 280 is arranged between the first conveying component 100 and the second conveying component 110 .

[0054] Therefore, the use of the PPU transplanting robot 280 to drive the clamping assembly to move can improve the feeding efficiency of the first stamping part 130, thereby adapting to high-speed welding.

[0055] In some embodiments of the present invention, referring to Figure 3, and also includes a distance-changing mechanism 360, which is located between the first conveying component 100 and the second conveying component 110. The distance-changing mechanism 360 includes a plurality of sliders 260 arranged side by side, and the adjacent sliders 260 can be arranged with variable distances in the horizontal direction. The sliders 260 are provided with positioning grooves, and the positioning grooves are used to accommodate the first stamping part 130. The material-picking component has a plurality of first adsorption heads 250 arranged side by side, and a plurality of second adsorption heads 270 arranged side by side. The spacing between two adjacent first adsorption heads 250 and the spacing between two adjacent second adsorption heads 270 are set differently. Before the distance is changed, the first adsorption head 250 can place the first stamping part 130 correspondingly in the positioning groove. After the distance is changed, the second adsorption head 270 can adsorb the first stamping part 130 from the positioning groove and stack the first stamping part 130 on the second stamping part 150.

[0056] The distance between adjacent first adsorption heads 250 is set according to the distance between the first stamping parts 130 on the first material strip 120, and the distance between adjacent second adsorption heads 270 is set according to the distance between the second stamping parts 150 on the second material strip 140. Therefore, there is a difference between the distance between adjacent first adsorption heads 250 and the distance between adjacent second adsorption heads 270. Before stacking the first stamping part 130 on the second stamping part 150, the distance between the adjacent first stamping parts 130 must be adjusted so that the second adsorption heads 270 can correctly adsorb the first stamping parts 130.

[0057] Therefore, the first adsorption head 250 can place the first stamping part 130 on the slider 260 of the distance changing mechanism 360, and the slider 260 adjusts the distance. Then, the second adsorption head 270 adsorbs the first stamping part 130 and stacks the first stamping part 130 on the second stamping part 150 to ensure that the relative positions of the first stamping part 130 and the second stamping part 150 are correct.

[0058] It should be noted that the pitch-changing mechanism 360 is a prior art, and the specific structure will not be described in detail here.

[0059] Among them, the welding mechanism includes a first positioning component 180, a second positioning component 190 and a welding component 200 arranged in the conveying direction of the second material strip 140. The first positioning component 180, the second positioning component 190 and the welding component 200 are distributed in sequence from bottom to top. The first positioning component 180 is used to position the second material strip 140, the second positioning component 190 is used to position the first stamping part 130, and the welding assembly 200 is used to weld the first stamping part 130 to the second stamping part 150.

[0060] It should be noted that the welding assembly 200 includes a body and a laser head extending from one side of the body, and the laser head welds the first stamping part 130 to the second stamping part 150 .

[0061] In some embodiments of the present invention, referring to Figure 8 The first positioning assembly 180 includes two limiting members 290 , which are arranged opposite to each other. A second limiting groove 300 is arranged on one side opposite to the two limiting members 290 , and the second limiting groove 300 accommodates the second material belt 140 to pass through.

[0062] Therefore, under the guidance of the second limiting groove 300 , the second stamping part 150 can accurately pass through the welding position, ensuring that the first stamping part 130 can be accurately stacked on the second stamping part 150 .

[0063] In a further embodiment of the present invention, the first positioning assembly 180 also includes a positioning pin located below the limiting member 290 and a second power member that drives the limiting member 290 to descend. The second material strip 140 is provided with a positioning hole 310 adapted to the positioning pin. The limiting member 290 descends to allow the positioning pin to be inserted into the positioning hole 310.

[0064] After the second stamping part 150 is transported to the welding position, the second power part is used to drive the limit part 290 to descend. The second power part can use a cylinder or other power source to achieve the lifting action. At the same time, under the restriction of the second limit groove 300, the second material strip 140 follows the limit part 290 to descend, so that the positioning pin and the positioning hole 310 are positioned and matched to ensure the correct welding position of the second stamping part 150.

[0065] In some embodiments of the present invention, the second positioning assembly 190 includes a limit frame 320 and a third power member that drives the limit frame 320 to descend. The limit frame 320 is provided with a limit channel 330 that passes through the upper and lower parts. The limit channel 330 accommodates the first stamping part 130 to pass through. The limit frame 320 descends to make the bottom end of the limit channel 330 close to the top of the second stamping part 150.

[0066] Therefore, the third power member is used to drive the limit frame 320 to descend, and the limit frame 320 is close to the top position of the second stamping part 150. The material moving mechanism stacks the first stamping part 130 on the second stamping part 150 through the limit channel 330. The limit channel 330 can stabilize the first stamping part 130 and reduce the deviation during welding.

[0067] In a further embodiment of the present invention, referring to Figure 4 , Figure 5 and Figure 6 The third power member is connected to the connecting frame 340, and the third power member drives the limiting frame 320 to descend through the connecting frame 340. The connecting frame 340 is provided with a welding channel 350. The second positioning assembly 190 also includes a fourth power member, and the fourth power member is used to drive the limiting frame 320 to move horizontally so that the limiting channel 330 moves out of or into the welding channel 350.

[0068] It is understandable that the fourth power member is fixed on the connecting frame 340 .

[0069] Therefore, when welding, refer to Figure 6 The fourth power member is used to drive the limit frame 320 to move into the welding channel 350, and then the third power member drives the connecting frame 340 to descend, so that the limit frame 320 and the connecting frame 340 descend synchronously. After welding, under the drive of the third power member, the limit frame 320 rises, and the fourth power member is used to drive the limit frame 320 to move out of the welding channel 350, thereby making it convenient for operators to observe the welding situation.

[0070] Therefore, the working principle of this embodiment is as follows:

[0071] First, the first material belt 120 and the second material belt 140 are respectively punched by a punch press to obtain the first stamping part 130 and the second stamping part 150 respectively. The first conveying assembly 100 and the second conveying assembly 110 convey the first material belt 120 and the second material belt 140 respectively, so that the first stamping part 130 and the second stamping part 150 are conveyed to the processing position.

[0072] Next, when the upper cutting die 160 and the lower cutting die 170 are closed, the first stamping part 130 is cut out from the first material strip 120 to obtain a single first stamping part 130, and the PPU transplanting robot 280 is used to drive the clamping assembly to move, and the first adsorption head 250 adsorbs the first stamping part 130 and places the first stamping part 130 on the slider 260 of the variable distance mechanism 360, and the slider 260 adjusts the spacing, and then, the second adsorption head 270 adsorbs the first stamping part 130 and prepares to stack the first stamping part 130 on the second stamping part 150.

[0073] At the same time, after the second stamping part 150 is transported to the welding position, the second power part is used to drive the limit part 290 to descend. The second power part can use a cylinder or other power source to achieve the lifting action. At the same time, under the restriction of the second limit groove 300, the second material strip 140 follows the limit part 290 to descend, so that the positioning pin and the positioning hole 310 are positioned and matched to ensure the correct welding position of the second stamping part 150.

[0074] In addition, the fourth power member drives the limit frame 320 to move into the welding channel 350, and then the third power member drives the limit frame 320 to descend through the connecting frame 340. The limit frame 320 is close to the top position of the second stamping part 150, and the second suction head 270 passes through the limit channel 330 to stack the first stamping part 130 on the second stamping part 150.

[0075] Finally, the laser head welds the first stamping part 130 to the second stamping part 150 .
