[0040] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0041] Example 1: See Figure 3-9 As shown, a pin plugging device comprises a pin feeding mechanism 41 and a pin insertion mechanism 42 mounted on a frame 1, wherein the pin insertion mechanism 42 is arranged beside the pin feeding mechanism 41;

[0042] The pin feeding mechanism 41 includes a pin feeding vibration plate 411, a pin feeding vibration track 412 and a pin pushing assembly 413. The rear end of the pin feeding vibration track 412 is connected to the discharge port at the front end of the pin feeding vibration plate 411, and the front end of the pin feeding vibration track 412 is connected to the pin pushing assembly 413.

[0043] The pin insertion mechanism 42 includes a pin clamping assembly 421 and a pin pushing assembly 422, wherein the pin pushing assembly 422 is connected to the pin clamping assembly 421, and the pin pushing assembly 422 is configured to drive the pin clamping assembly 421 to move forward and backward, so that the front end of the pin clamping assembly 421 is arranged on the left side of the pin pushing assembly 422 or moves forward and away from the pin pushing assembly 421;

[0044] The pin pushing assembly 422 feeds the pins sent out by the pin feeding vibration track 412 to the pin clamping assembly 421 one by one.

[0045] In this embodiment, when in use, the pins are placed in the pin feeding vibration plate, sorted and loaded through the pin feeding vibration plate, and transported to the pin feeding vibration track, and then transported to the pin pushing assembly through the pin feeding vibration track, and sent one by one to the pin insertion mechanism through the pin pushing assembly, and the pins are clamped by the pin insertion mechanism, and then the pin pushing assembly pushes the pin clamping assembly and the pins thereon to move forward, and then the pins are inserted into the shell, realizing the automatic insertion of the pins into the shell, or realizing the automatic and semi-automatic plugging of the shell and the pins (the shell can be placed on the front side of the pin insertion mechanism manually, or it can be automatically fed to the front side of the pin insertion mechanism). In this way, the stability is good, and the pin clamping assembly can stably clamp the pins.

[0046] See also Figure 3 , 4 As shown, the pin pushing assembly 413 includes a pin positioning block 4130, a pin pushing block 4131 and a pin pushing cylinder 4132. The pin positioning block 4130 is provided with a pin accommodating cavity 4133, and the pin accommodating cavity 4133 is connected to the front end of the pin feeding vibration track 412;

[0047] The pin pushing block 4131 is movably arranged in the pin accommodating cavity 4133, the pin pushing cylinder 4132 and the pin clamping assembly 421 are respectively arranged on both sides of the pin positioning block 4130, the output shaft of the pin pushing cylinder 4132 is connected to the side of the pin pushing block 4131, and the pin pushing cylinder 4132 is configured to drive the pin pushing block 4131 to be close to or away from the pin clamping assembly 421.

[0048] In this embodiment, the length of the pin accommodating cavity matches the length of a pin, or is slightly larger than the length of the pin. Therefore, after the pin feeding vibration track feeds the frontmost pin into the pin accommodating groove, the subsequent pins cannot enter, or cannot enter the pin accommodating groove completely. Then the output shaft of the pin pushing cylinder extends, driving the pin pushing block to move toward the pin clamping assembly, and pushes the pin in the pin accommodating cavity out and onto the pin clamping assembly. The pin is clamped by the pin clamping assembly to perform subsequent actions. Then the output shaft of the pin pushing cylinder retracts, driving the pin pushing block to move away from the pin clamping assembly, so that it moves back to the original state, and waits for another subsequent pin to move forward into the pin accommodating cavity, waiting for the next pin to be pushed onto the pin clamping assembly, and so on. At the same time, during the movement, the pin push block will also block the pins that the pin feeding vibration track wants to transport forward, so that after the pin push block returns to its position, the pins can normally enter the pin accommodating cavity and be located on the side of the pin push block, making it easier for the pin push block to push the pins to move.

[0049] See also Figure 3-8 As shown, the pin pushing assembly 422 includes a second pushing cylinder 4220 and a second longitudinal slide rail 4221. The second longitudinal slide rail 4221 is arranged perpendicular to the output shaft of the pin pushing cylinder 4132. The pin clamping assembly 421 is slidably installed on the second longitudinal slide rail 4221. The second pushing cylinder 4220 is configured to drive the pin clamping assembly 421 to move forward and backward.

[0050] The extension and retraction of the output shaft of the second push cylinder drives the pin clamping assembly to move forward and backward. When it moves backward, the pin clamping assembly is located at the side of the pin accommodating chamber (in this embodiment, the pin clamping assembly is located at the left side of the pin accommodating chamber, and the pin pushing cylinder is located at the right side of the pin accommodating chamber). When the output shaft of the second push cylinder extends, it drives the pin clamping assembly and the pin clamped thereon to move forward. A feeding slide is provided at the front side of the pin clamping assembly. A feeding chamber is provided in the feeding slide. The shell is located in the feeding chamber. When the second push cylinder drives the pin clamping assembly and the pin to move forward, the pin is inserted into the shell to achieve the connection between the pin and the shell. After the connection between the pin and the shell is completed, the pin clamping assembly releases the clamping of the pin, and the pin is located on the shell. The provision of the second longitudinal slide rail can ensure the stable forward and backward movement of the pin clamping assembly and the quality of the connection between the pin and the shell.

[0051] See also Figure 3-9 As shown, the pin clamping assembly 421 includes a second mounting block 4210, a pin clamping member 4211 mounted on the second mounting block 4210, and a clamping cylinder 4212, and the pin pushing assembly 422 is connected to the second mounting block 4210, and the pin pushing assembly 422 is configured to drive the second mounting block 4210 to move forward and backward;

[0052] The pin clamping member 4211 includes a fixed clamping block 42110 and a movable clamping block 42111. The rear end of the fixed clamping block 42110 is connected to the front end of the second mounting block 4210. The movable clamping block 42111 is vertically movable and arranged directly above the fixed clamping block 42110.

[0053] The clamping cylinder 4212 is connected to the movable clamping block 42111 via a second connecting member, and the clamping cylinder 4212 drives the movable clamping block 42111 to be disposed close to or away from the fixed clamping block 42110 via the second connecting member.

[0054] In this embodiment, the second push cylinder is connected to the second mounting block, and the second mounting block is slidably connected to the second longitudinal slide rail. The extension and retraction of the output shaft of the second push cylinder drive the pin clamping assembly to move forward and backward. The extension and retraction of the output shaft of the clamping cylinder drive the movable clamping block to approach or move away from the fixed clamping block. A clamping space is formed between the fixed clamping block and the movable clamping block. The clamping space is used for clamping the pin. When the movable clamping block approaches the fixed clamping block, the clamping space is reduced, thereby clamping the pin. When the movable clamping block moves away from the fixed clamping block, the clamping space is increased, thereby releasing the pin. After the pin and the shell are plugged in, the pin is released. When the pin clamping assembly needs to move away from the shell, the pin plugged into the shell will not be removed from the shell, thereby ensuring the quality of the plugging.

[0055] See also Figure 7-9 As shown, the second connecting member includes a second vertical slider 4213 and a second longitudinal push plate 4214, and the second mounting block 4210 is provided with a second vertical slide groove 4215 and a second longitudinal slide groove 4216 which are connected to each other, the second vertical slider 4213 is vertically slidably disposed in the second vertical slide groove 4215, and the second longitudinal push plate 4214 is longitudinally slidably disposed in the second longitudinal slide groove 4216;

[0056] The second longitudinal push plate 4214 is provided with a push guide groove 4217 which is inclined upward from the back to the front. A push guide wheel 4218 is installed on the side of the second vertical slide block 4213. The push guide wheel 4218 penetrates into the second longitudinal slide groove 4215 and is inserted into the push guide groove 4217.

[0057] The width of the pushing guide groove 4217 matches the outer diameter of the pushing guide wheel 4218, and the length of the pushing guide groove 4217 is greater than the outer diameter of the pushing guide wheel 4218;

[0058] The output shaft at the front end of the clamping cylinder 4212 is connected to the rear end of the second longitudinal push plate 4214. When the clamping cylinder 4212 drives the second longitudinal push plate 4214 to move forward and backward, it drives the pushing guide wheel 4218 to move up and down through the pushing guide groove 4217, and at the same time drives the second vertical slider 4213 to move up and down along the second vertical slide groove 4215.

[0059] See also Figure 7-9As shown, a second through groove 4219 is provided on the front side of the second mounting block 4210 and is connected to the middle part of the second vertical slide groove 4215, a push groove 4230 is provided on the front side of the second vertical slide block 4213 and is directly opposite to the second through groove 4219, and a movable connecting block 4231 is provided at the rear end of the movable clamping block 42111, and the rear end of the movable connecting block 4231 passes through the second through groove 4219 and is inserted into the push groove 4230;

[0060] The top and bottom of the movable connection block 4231 are respectively against the top and bottom surfaces of the push groove 4230;

[0061] When the second vertical sliding block 4213 moves up and down along the second vertical sliding groove 4215 , the movable clamping block 42111 is driven to move up and down via the movable connecting block 4231 , so that the movable clamping block 42111 is arranged close to or away from the fixed clamping block 42110 .

[0062] When the output shaft of the clamping cylinder extends, it will drive the second longitudinal push plate to move forward, and the pushing guide groove will move forward relative to the pushing guide wheel. In this process, since the pushing guide groove is tilted upward from the back to the front, the pushing guide groove will drive the pushing guide wheel to move downward. When the pushing guide wheel moves downward, it will simultaneously drive the second vertical slider to move downward. When the second vertical slider moves downward, the downward movement of the push groove will drive the movable connection block and the movable clamping block to move downward, so that the movable clamping block is close to the fixed clamping block. Similarly, when the output shaft of the clamping cylinder retracts, it drives the second longitudinal push plate to move backward, and the pushing guide groove drives the pushing guide wheel to move upward, so that the movable clamping block is away from the fixed clamping block. In this way, when the movable clamping block clamps the pin on the fixed clamping block, it can tightly clamp the pin, and the firmness and stability are better.

[0063] Furthermore, the rear end of the push guide groove 4217 is provided with a horizontal groove 4232 extending backwards, and the horizontal groove 4232 is arranged parallel to the output shaft of the clamping cylinder 4212. After the output shaft of the clamping cylinder is extended, the push guide wheel will be in the horizontal groove, so that even if the output shaft of the clamping cylinder is partially retracted (if the air source for the cylinder is unstable, there is a problem of insufficient air pressure causing the output shaft of the clamping cylinder to be extended and slightly retracted), the second vertical slider will not move up and down at this time, thereby ensuring the stability of the clamping of the pin.

[0064] Wherein, at least one vertical guide rod is provided on the top of the fixed clamping block, the movable clamping block is movably connected to the vertical guide rod, and the movable clamping block is vertically moved through the vertical guide rod and arranged directly above the fixed clamping block.

[0065] By setting the vertical guide rod, when the movable clamping block moves up and down, it can be ensured to move up and down accurately relative to the fixed clamping block, thereby ensuring the clamping quality and stability of the pin.
