[0019] See also Figures 1 to 5 A gel pen refill set machine comprises a base plate 1, a material discharge box 2 is installed on the base plate 1, a material guide tube 201 is fixedly connected to one side of the material discharge box 2, a symmetrical material guide rod 202 is fixedly connected to one side of the material guide tube 201, a servo motor 3 is installed on the base plate 1, a telescopic cylinder 303 is installed at the output end of the servo motor 3, a flip cylinder 305 is installed at the output end of the telescopic cylinder 303, a telescopic cylinder 303 is installed at the output end of the flip cylinder 305, and a finger clamp cylinder 304 is installed at the output end of the telescopic cylinder 303.

[0020] Among them, first, the flipping cylinder 305 drives the finger clamp cylinder 304 to flip 90°, and then the output end of the finger clamp cylinder 304 moves to the left to clamp the pen core on the guide rod 202 (the pen core and the base plate 1 remain parallel), and then the output end of the finger clamp cylinder 304 moves to the right, and the flipping cylinder 305 drives the finger clamp cylinder 304 to return to the initial angle (the pen core and the base plate 1 remain vertical), and then the telescopic cylinder 303 is used to control the pen core to move downward, so that the pen core is inserted into the pen tip in the pen tip clamp block 4.

[0021] A transport rack 301 is arranged on the outside of the servo motor 3, and a plurality of pen tip clamp blocks 4 are arranged on the transport rack 301. A clamping groove 401 is provided inside the pen tip clamp block 4. A telescopic groove 402 is provided on the lower side of the clamping groove 401, and a pressing groove 407 is provided on the lower side of the telescopic groove 402. A connecting rod 408 is provided inside the pressing groove 407. An elastic card block 409 is fixedly connected to the side wall of the connecting rod 408. A limiting card groove 410 is provided on the side wall of the pressing groove 407. A sliding plate 403 is slidably connected to the inner wall of the telescopic groove 402. Two groups of sliding rods 404 are fixedly connected to the sliding plate 403. The two groups of sliding rods 404 are both slidably connected to the clamping rod 406, and the two groups of sliding rods 404 are both sleeved with a return spring 405.

[0022] Preferably, an inclined material guide plate 204 is installed inside the discharge box 2, a discharge port is opened on the discharge box 2, a discharge port is opened on the side of the discharge box 2, and the discharge port is connected with the material guide pipe 201.

[0023] The inclined guide plate 204 is provided to facilitate the refills in the discharge box 2 to roll onto the guide rod 202 through the guide tube 201 , so as to facilitate the clamping of the finger clamp cylinder 304 .

[0024] Preferably, spring blocks 203 are installed on the symmetrical material guiding rods 202 , and through grooves are provided between the symmetrical material guiding rods 202 .

[0025] Among them, the spring block 203 is provided to block the pen refill rolling out from the inside of the discharge box 2, thereby preventing the pen refill from falling off the guide rod 202. When the finger clamp cylinder 304 clamps the pen refill and moves to the right, pressure is applied to the spring block 203, so that the spring block 203 is immersed in the inside of the guide rod 202, thereby making it easier for the finger clamp cylinder 304 to clamp the pen refill.

[0026] Preferably, the transport frame 301 is installed on the base plate 1 , a conveyor belt 302 is installed on the transport frame 301 , the pen tip fixture block 4 is placed on the conveyor belt 302 , and the servo motor 3 is located in the middle of the transport frame 301 .

[0027] The conveyor belt 302 of the transport frame 301 can drive the nib fixture block 4 to move, so that the pen core can be inserted into the nib in the nib fixture block 4 .

[0028] Preferably, the clamping rod 406 extends to the inside of the clamping groove 401, and the clamping rod 406 is arranged in a "7" shape.

[0029] The symmetrical clamping rods 406 arranged in a "7" shape will approach each other when moving downward, thereby being able to clamp the pen tip.

[0030] Preferably, the bottom wall of the pressing groove 407 is fixedly connected to the connecting rod 408 via a pressing spring 411 .

[0031] Among them, the set pressing spring 411 plays a buffering role when the connecting rod 408 moves downward inside the pressing groove 407, thereby avoiding direct contact between the connecting rod 408 and the bottom wall of the pressing groove 407, and the elastic force of the pressing spring 411 will cause the connecting rod 408 to move upward. When the elastic block 409 moves upward, it will overcome the clamping force with the limiting groove 410, causing the elastic block 409 to move to the upper side of the limiting groove 410.

[0032] Working principle: When working, first, the turning cylinder 305 drives the finger clamp cylinder 304 to turn 90°, then the output end of the finger clamp cylinder 304 moves to the left to clamp the pen core on the guide rod 202 (the pen core and the bottom plate 1 remain parallel), then the output end of the finger clamp cylinder 304 moves to the right, the turning cylinder 305 drives the finger clamp cylinder 304 to return to the initial angle (the pen core and the bottom plate 1 remain vertical), and then the telescopic cylinder 303 controls the pen core to move downward, so that the pen core is inserted into the pen tip in the pen tip clamp block 4; the pen tip is plugged into the two sets of clamping rods When the pen tip is inserted between the two groups of clamping rods 406, the clamping rod 406 is driven to move downward, and the clamping rod 406 is connected with the telescopic slot 402 when the clamping rod 406 moves downward, thereby driving the tail ends of the two groups of clamping rods 406 to approach each other on the sliding rod 404, thereby clamping the pen tip. At the same time, the downward movement of the clamping rod 406 drives the sliding plate 403 to move downward, and the downward movement of the sliding plate 403 drives the connecting rod 408 to move downward inside the pressing slot 407, so that the elastic block 409 is engaged with the inside of the limiting slot 410, thereby The connecting rod 408 fixes the position of the clamping rod 406 inside the telescopic groove 402, thereby clamping the pen tip. When the telescopic cylinder 303 controls the pen core to be inserted into the pen tip, the telescopic cylinder 303 transmits pressure to the pen tip through the pen core, so that the pen tip drives the connecting rod 408 to continue to move downward through the clamping rod 406, so that the elastic block 409 is separated from the limit slot 410 and applies pressure to the pressing spring 411 through the connecting rod 408. When the pen tip is completely inserted into the pen core (interference fit), the output end of the telescopic cylinder 303 moves upward, and the telescopic cylinder 303 drives the pen core to move downward. When the pen tip moves upward, the upward pulling force generated and the elastic force of the pressing spring 411 will cause the connecting rod 408 to move upward. When the elastic block 409 moves upward, it will overcome the clamping force with the limiting slot 410, causing the elastic block 409 to move to the upper side of the limiting slot 410, and when the connecting rod 408 moves upward, it drives the clamping rod 406 to move upward, so that the pen tip loses the clamping force, completing the assembly of the pen core and the pen tip; the above structure can clamp the pen tip through the cooperation of the elastic block 409 on the connecting rod 408 and the limiting slot 410, thereby preventing the pen tip from falling off during the rotating transportation process.
