[0037] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0038] The present invention proposes a plastic seal lock core assembly device, including a workbench 1 and a seal pressing mechanism 2, a seal moving mechanism, a lock core stamping mechanism, a lock core band pulling mechanism and a lock core band placing mechanism arranged on the workbench 1, the plastic seal 24 is installed in the seal pressing mechanism 2, the seal pressing mechanism 2 is installed on the first slide of the seal moving mechanism, the seal pressing mechanism 2 can be moved to the bottom of the lock core stamping mechanism, the lock core band pulling mechanism is arranged at the rear side of the lock core stamping mechanism, and the lock core band 401 in the lock core band placing mechanism is inserted into the lock core stamping mechanism.

[0039] The above device is provided for stamping and assembling the lock core in the lock core strip 401 to the plastic seal 24. The device is controlled by a PLC control system. As long as the lock core hole of the plastic seal 24 is the same size, the plastic seal 24 that can be inserted into the seal pressing mechanism 2 can be used in the device to assemble the lock core. The lock core strip is a strip that is first stamped on a stamping bed to form a lock core shape, and then the stamped lock core of the device is inserted into the plastic seal 24.

[0040] The seal pressing mechanism 2 includes a moving block 21, a seal pressing plate 23, and a seal limiting plate 22. The seal limiting plate 22 is installed above the moving block 21. The seal pressing plate 23 fixes the seal limiting plate 22 on the moving block 21. A gap is provided between the seal limiting plate 22 and the moving block 21 for inserting the plastic seal 24. A seal limiting notch 221 is provided on one side of the seal limiting plate 22. First sliders are provided on both sides below the moving block 21, and a first slide groove 25 is provided between the first sliders 26.

[0041] The lock core installation position of the plastic seal 24 is a cylindrical shape with a hole groove, and the seal limiting plate 22 limits the plastic seal, that is, limits the position of the cylinder. Therefore, the seal limiting notch 221 of the present application is a semicircular notch, and the cylinder is just stuck here. The plastic seal is manually installed in the gap.

[0042] The seal moving mechanism includes a servo motor 3, a screw 31, two slideways, and a screw seat 32. Screw seats 32 are provided at both ends of the screw 31. The shaft of the servo motor 3 is connected to one end of the screw 31 through a coupling. A screw slider is sleeved on the screw 31. The two slideways are arranged in parallel and symmetrically on both sides of the screw 31. The screw slider under the moving block 21 is installed on the first slideway. The screw slider is arranged in the first slide groove 25 and fixed under the moving block 21.

[0043] The servo motor 3 is accurately positioned and can accurately rotate the screw rod 31 to ensure that the seal pressing mechanism 2 can accurately move below the lock core punching mechanism, ensuring that a lock core can be punched in the lock core hole of each plastic seal 24 without deviation.

[0044] The lock core stamping mechanism includes a stamping cylinder 5 and a stamping structure 4, and the stamping structure 4 includes a stamping frame 46, a stamping rod 43, a clamping block 42, and a stamping block 44. A stamping cylinder 5 is arranged on the frame above the stamping frame 46, and the cylinder shaft of the stamping cylinder 5 is connected to the stamping block 44 through a second coupling 45. A stamping rod 43 is fixed at the center position below the stamping block 44, and a clamping block 42 is arranged below the stamping block 44 and the stamping rod 43 passes through the clamping block 42. A lock core belt groove 40 is arranged on the upper surface of the bottom plate of the stamping frame 46, and a lock core through hole is arranged on the stamping rod 43 opposite to the lock core belt groove 40, and the clamping block 42 and the stamping block 44 are limited by a limiting rod 41.

[0045] When punching begins, the pressing block 42 and the punching block 44 will move downward, and the pressing block 42 will press the lock core belt 401 to prevent the lock core belt from shaking when the punching rod 43 punches, causing punching errors, and the lock core cannot be punched into the lock core hole, which will damage the equipment. The lock core punching mechanism punches the lock core one by one to reduce punching errors.

[0046] The punching rod 43 is a hollow cylindrical shape, and the punching rod 43 is symmetrically provided with two punching ribs 431. The hollow cylindrical shape can be stuck on the lock core, and the lock core and the lock core belt 401 are connected by two ribs, and the punching ribs 431 are just opposite to the ribs on both sides of the lock core on the lock core belt 401. When punching, the ribs can be broken to ensure that the lock core is punched into the lock core hole of the plastic seal 24.

[0047] The lock core belt placement mechanism includes a material tray 6 and a material tray mounting frame 61 . A lock core belt 401 is mounted on the material tray 6 . The lock core belt 401 is drawn out from the material tray 6 and inserted into the lock core belt slide groove 40 .

[0048] The lock core belt pulling mechanism includes a pulling cylinder 8, a pulling block 7, and a clamping strip 701. The pulling cylinder 8 is connected to the pulling block 7 through a coupling. A slideway is provided below the pulling block 7. The pulling block is provided with a square slot 71. An axle pin hole 711 is provided in the square slot 71. The clamping strip 701 is installed in the square slot 71 through an axle pin. Since a round hole (left after the lock core is punched out) is left on the lock core belt after being punched, the clamping strip 701 can be stuck in the hole, and the pulling cylinder 8 can pull the pulling block 7, thereby driving the clamping strip 701 to move. When the clamping strip moves toward the lock core punching mechanism, it will move to a hole left after a lock core is flushed away. Then the pulling cylinder 8 pulls the pulling block 7 back, and the clamping strip 701 will pull the lock core belt backward, so that the lock core belt can be punched for the next lock core.

[0049] The lower half of the clamping strip 701 is wedge-shaped 7011, and a spring mounting hole is provided at the top of the clamping strip 701. A spring 702 is installed at the top of the clamping strip 701. The spring 702 ensures that when the clamping strip 701 clamps the hole on the lock core belt 401, the clamping strip is straight and convenient for positioning the hole.

[0050] A process for assembling a plastic seal lock core, the specific processing steps are as follows:

[0051] 1) including the step of placing the plastic seal 24 in the seal pressing mechanism 2;

[0052] 2) comprising the step of moving the seal pressing mechanism 2 of the placed plastic seal 24 to the lock core punching mechanism through the seal moving mechanism;

[0053] 3) including the step of inserting the lock core belt 401 on the material tray 6 into the lock core stamping mechanism;

[0054] 4) including the step of a lock core punching mechanism carrying the lock core onto the lock core and punching the lock core into the plastic seal one by one;

[0055] 5) A lock core belt pulling mechanism is included to pull the lock core belt 401 backwards a certain distance after each lock core is punched.

[0056] First, manually insert the plastic seals 24 into the gap of the seal pressing mechanism 2 one by one to ensure that the cylinder on the lock core of the plastic seal 24 can be stuck in the seal limit notch 221. After the plastic seal 24 is placed, the servo motor 3 starts to work and moves the seal pressing mechanism 2 to the lock core punching mechanism so that the lock core installation hole of the first plastic seal 24 is opposite to the lock core through hole. Then the lock core punching mechanism punches the lock core on the lock core belt 401 so that the lock core is punched into the lock core hole. Then the lock core is installed on the plastic seal 24 in turn. The pull-out cylinder 8 pushes the pull-out block 7 to move forward, and the card strip 701 is inserted into the hole left by the punching lock core belt 401. Then the pull-out block 7 is pulled back to drive the lock core belt 401 to move backward for a distance to ensure that the lock core belt is punched for the next lock core. The above process is repeated to complete the industrialization of lock core assembly.
