[0053] Embodiment 1:

[0054] See also Figure 1 and Figure 2The present embodiment provides a laser feeding mechanism, which includes: a machine frame 110, a feeding movement module 120, a feeding movement module 120, a stitch piece merging module 130 and an adsorption module 140. The feeding movement module 120 is arranged on the machine frame 110, the stitch piece merging module 130 is arranged on the feeding movement module 120, and the adsorption module 140 is connected to the stitch piece merging module 130 and forms a parallel arrangement structure with the stitch piece merging module 130.

[0055] In this embodiment, the laser feeding mechanism 100 is used to absorb and transfer the pin parts of the laser from the feeding tray 200, wherein the pin parts are embedded in the accommodating tooling of the feeding tray 200. When feeding, the feeding movement module 120 can drive the pin part merging module 130 and the adsorption module 140 to move toward the side of the upper feeding tray 200. When the feeding movement module 120 drives the pin part merging module 130 and the adsorption module 140 to move downward, the pin part merging module 130 can apply pressure to the pin parts to make the pin parts pinch together, which is equivalent to imitating the action of pinching the pins of the pin parts by the middle thumb and index finger to merge them. After that, the merged pin parts are absorbed and transferred to the welding station 510 ( Figure 3 ).

[0056] The working process of the laser feeding mechanism 100 is as follows:

[0057] 1. Manually assemble the loading tray 200, wherein the loading tray 200 contains a plurality of rows of pin parts.

[0058] 2. The feeding movement module 120 drives the stitch piece merging module 130 and the adsorption module 140 to move toward the side of the upper feeding tray 200, and moves the stitch piece merging module 130 to position No. 1 of the feeding tray 200. At this time, the adsorption module 140 is located at position No. 0 of the feeding tray 200, and position No. 0 is equivalent to the outside of the feeding tray 200 or there is no stitch piece at this position.

[0059] 3. The feeding movement module 120 drives the pin piece merging module 130 and the adsorption module 140 to move downward, and applies pressure to the pin piece at position 1 for 0.5 seconds through the pin piece merging module 130.

[0060] 4. The feeding movement module 120 drives the stitch piece merging module 130 and the adsorption module 140 to move upward, and then drives the stitch piece merging module 130 and the adsorption module 140 to move to the right, so that the stitch piece merging module 130 is located at position 2 of the feeding tray 200, and the adsorption module 140 is located at position 1 of the feeding tray 200.

[0061] 5. The feeding movement module 120 drives the pin piece merging module 130 and the adsorption module 140 to move downward, and applies pressure to the pin piece at position No. 2 for 0.5s through the pin piece merging module 130, and at the same time adsorbs the pin piece at position No. 1 through the adsorption module 140.

[0062] 6. The feeding movement module 120 drives the pin component merging module 130 and the adsorption module 140 to move upward, and transfers the pin component to the welding station 510 of the discharge pressing welding mechanism 500 through the adsorption module 140 to wait for the welding process of the discharge pressing welding mechanism 500.

[0063] 7. The feeding movement module 120 drives the pin part merging module 130 and the adsorption module 140 to reset, and then drives the pin part merging module 130 to move to position No. 3, and the adsorption module 140 to move to position No. 2. Then, the pin part merging module 130 applies pressure to the pin part at position No. 3, and at the same time, the adsorption module 140 completes the adsorption of the pin part at position No. 2.

[0064] 8. Repeat the above steps of applying pressure, combining, and adsorbing and transferring the pins.

[0065] Therefore, in this embodiment, the stitch piece merging module 130 and the adsorption module 140 are both arranged on the feeding movement module 120, and the stitch piece merging module 130 and the adsorption module 140 form a parallel arrangement structure. When the feeding movement module 120 drives the adsorption module 140 to adsorb the stitch pieces, the stitch piece merging module 130 can press down and merge the stitch pieces in advance. The stitch piece merging module 130 and the adsorption module 140 share a feeding movement module 120, which has a simple structure, realizes automatic pressure application and automatic feeding of stitch pieces, has high working efficiency, and effectively saves labor costs.

[0066] Specifically, see Figure 2 The feeding motion module 120 includes: a feeding base 150, an X-axis motion mechanism 160 and a Z-axis motion mechanism 170. The X-axis motion mechanism 160 is arranged on the feeding base 150 along the X direction, and the Z-axis motion mechanism 170 is arranged on the X-axis motion mechanism 160 along the Z direction. The X-axis motion mechanism 160 is used to drive the stitch piece merging module 130 and the adsorption module 140 to move along the X direction. For example, a discharge pressing welding mechanism 500 is arranged on the left side of the feeding tray 200. The X-axis motion mechanism 160 can drive the adsorption module 140 to move back and forth between the feeding tray 200 and the discharge pressing welding mechanism 500. The Z-axis motion mechanism 170 is used to drive the stitch piece merging module 130 and the adsorption module 140 to move along the Z direction. For example, the Z-axis motion mechanism 170 can drive the stitch piece merging module 130 and the adsorption module 140 to move up and down, so as to realize the pressure merging and transportation transfer of the stitch pieces.

[0067] Specifically, see Figure 3 The loading base 150 includes: a Y-axis adjustment mechanism 151 and a mounting base plate 152. The Y-axis adjustment mechanism 151 is arranged on the machine frame 110 along the Y direction, and the mounting base plate 152 is connected to the Y-axis adjustment mechanism 151 and the X-axis motion mechanism 160. The Y-axis adjustment mechanism 151 can move the X-axis motion mechanism 160 along the Y direction to realize the Y-direction movement of the stitch piece merging module 130 and the adsorption module 140. For example, when the Y-direction coordinate of the welding station 510 of the discharge pressing welding mechanism 500 changes, the Y-direction coordinate of the adsorption module 140 can be adjusted to be consistent with the Y-direction coordinate of the welding station 510 by adjusting the Y-axis adjustment mechanism 151, wherein the Y-axis adjustment mechanism 151 can be automatically adjusted by a motor drive, or manually adjusted by a handle drive.

[0068] Specifically, see Figure 2 The X-axis motion mechanism 160 includes: a first base 161, a first stepping motor 162 and a first screw module 163. The first base 161 is connected to the feeding base 150, the first stepping motor 162 is installed on the first base 161, and the first screw module 163 is installed on the first base 161 and is in transmission connection with the first stepping motor 162. It can be understood that the X-axis motion mechanism 160 realizes movement along the X direction through the screw stepping motor, and the first screw module 163 can realize directional movement through the guide rail and the slider, and the slider is driven by the stepping motor, and its movement is stable, which is conducive to improving the accuracy and stability of the movement of the pin component merging module 130 and the adsorption module 140.

[0069] Specifically, see Figure 2 The Z-axis motion mechanism 170 includes: a second base 171, a second stepping motor 172 and a second screw module 173. The second base 171 is connected to the X-axis motion mechanism 160, the second stepping motor 172 is installed on the second base 171, and the second screw module 173 is installed on the second base 171 and is in transmission connection with the second stepping motor 172. It can be understood that the Z-axis motion mechanism 170 realizes movement along the Z direction through the screw stepping motor, and the second screw module 173 can realize directional movement through the guide rail and the slider, and the slider is driven by the stepping motor, and its movement is stable, which is conducive to improving the accuracy and stability of the lifting and lowering movement of the pin component merging module 130 and the adsorption module 140.

[0070] Specifically, see Figure 2The pin piece merging module 130 includes: a pin piece connecting component 131, an X-direction connecting horizontal plate 132 and a pressing sleeve 133. The pin piece connecting component 131 is used to connect with the feeding movement module 120, the X-direction connecting horizontal plate 132 is connected to the pin piece connecting component 131 along the X-direction, and the pressing sleeve 133 is arranged on the X-direction connecting horizontal plate 132. During the X-axis movement, the X-axis connecting transverse plate 132 can extend the X-axis movement scale of the pressing sleeve 133 and the adsorption module 140. For example, the discharge pressing welding mechanism 500 is located on the left side of the laser feeding mechanism 100. When the X-axis motion mechanism 160 drives the X-axis connecting transverse plate 132 and the adsorption module 140 to move toward the side of the discharge pressing welding mechanism 500, the laser feeding mechanism 100 can insert the adsorption module 140 into the welding station 510 of the discharge pressing welding mechanism 500 through the X-axis connecting transverse plate 132, thereby avoiding interference between the X-axis motion mechanism 160 and the discharge pressing welding mechanism 500.

[0071] Specifically, see Figure 2 The adsorption module 140 includes a first suction nozzle 141, which is connected to the X-direction connecting horizontal plate 132 and arranged in parallel with the pressing sleeve 133. In this embodiment, the first suction nozzle 141 is used to adsorb the pin parts, wherein the first suction nozzle 141 is arranged in parallel with the pressing sleeve 133 to achieve the pressure-combining and adsorption-transfer functions of the pin parts.

[0076] In this embodiment, the loading tray 200 is located on one side of the laser loading mechanism 100. The loading tray 200 is used to accommodate pin parts. For example, the first tray body 230 of the loading tray 200 accommodates a plurality of rows of pin parts. The laser loading mechanism 100 sequentially performs the pressure merging and loading and transferring processes from the loading tray 200. After the loading of the first row of pin parts on the loading tray 200 is completed, the Y-axis motion mechanism 210 can drive the first tray body 230 to move in the Y direction, so that the second row of pin parts are located below the pin part merging module 130 and the adsorption module 140. When the second row of pin parts are loaded, the Y-axis motion mechanism 210 can drive the first tray body 230 to move in the Y direction, so that the third row of pin parts are located below the pin part merging module 130 and the adsorption module 140. Repeat the above steps until all the pin parts of the first tray body 230 are loaded. When the pin parts of the entire first tray body 230 are loaded, the first tray body 230 can be disassembled and then replaced with a new first tray body 230. The Y-axis mounting base 220 can facilitate the disassembly of the first tray body 230 and the Y-axis motion mechanism 210.
