[0038] Furthermore, the cleaning mechanism includes two groups of brush cylinders 63, the left and right sides of the brush cylinder 63 are rotatably connected to the connecting piece 62, the bottom end of the brush cylinder 63 contacts the top of the light-transmitting plate 41, the side of the connecting piece 62 away from the brush cylinder 63 is fixedly connected to the top of the insertion rod 58, the top of the insertion rod 58 is inserted on the sliding rod 60, the front and rear sides of the sliding rod 60 are fixedly connected to the protrusion 59, the protrusion 59 is fixedly connected to the top of the pressing plate 40, the bottom end of the insertion rod 58 is inserted in the sleeve block 54, and the sleeve block 54 is trapezoidal in design.

The side of the second spring 56 away from the sleeve block 54 is fixedly connected to a retaining frame 57. The side of the movable rod 55 away from the sleeve block 54 is inserted on the retaining frame 57. The bottom end of the retaining frame 57 is fixedly connected to the processing platform 1. The bottom end of the sleeve block 54 abuts against the inclined groove 53. The inclined groove 53 is provided at the top of the clamping block 50. A notch 52 is provided on the inclined groove 53. The notch 52 passes through the clamping block 50.

[0039] The structural design of the clamping mechanism realizes the function of conveniently clamping and fixing the plastic parts on the jig body 23. When working, the plastic parts to be welded are first placed on the jig body 23, and the jig body 23 is provided with corresponding slots for placement. Then, the jig body 23 is pushed forward, and the bottom end of the jig body 23 is slidably connected to the two sets of support rods 24, thereby avoiding contact with the top of the processing platform 1 and reducing the friction resistance of movement. The front and rear sides of the support rods 24 are fixed on the fixing blocks 25, and the fixing blocks 25 are used to clamp the jig body 23 on the support The movement of the support rod 24 is limited to ensure that when the jig body 23 moves forward to the position abutting against the fixing block 25, the jig body 23 can be located directly below the clamping plate 40 to facilitate the positioning of the jig body 23. After the jig body 23 moves into place, the fixing mechanism releases the fixing of the rotating rod 34. At this time, rotating the knob 29 can drive the rotating rod 34 inside the cavity 26 to rotate. The rotating rod 34 transmits the rotation to the second bevel gear 35 through the meshing of the first bevel gear 33 and the two sets of second bevel gears 35, thereby driving the second bevel gear 35 to rotate. The rotating disk 38 is driven to rotate through the transmission rod 36. The transmission rod 36 is rotatably connected with a support ring 37 to support the transmission rod 36. During the rotation of the rotating disk 38, the connecting rod 39 located on the top of the rotating disk 38 will gradually move to the bottom of the rotating disk 38, thereby driving the clamping plate 40 at the top of the connecting rod 39 to move downward until the bottom of the clamping plate 40 clamps the jig body 23 and the plastic parts placed in the jig body 23. At this time, the laser generator 22 is irradiated on the plastic parts to perform welding operations. After the welding is completed, the knob 29 is rotated in the opposite direction again, and the connecting rod 39 at the bottom of the rotating disk 38 will move back to the top of the rotating disk 38, thereby lifting the clamping plate 40 to release the clamping of the jig body 23, and finally the jig body 23 is pulled out from under the clamping plate 40 to remove the plastic part. Four groups of plug posts 65 are inserted on the clamping plate 40 to guide the clamping plate 40 when it moves, and a light-transmitting plate 41 is fixed in the middle of the clamping plate 40 to compress the plastic part without blocking the laser beam.

[0040] Through the structural design of the clamping mechanism, the left and right sides of the jig body 23 can be clamped and fixed while the jig body 23 is pressed and fixed, so as to ensure that the position of the jig body 23 on the processing platform 1 will not be offset during the operation of the jig body 23, so that the fixing effect of the jig body 23 is better. When the second bevel gear 35 drives the transmission rod 36 to rotate, since the transmission rod 36 is provided with threads and the rotation directions are opposite, the moving blocks 49 threadedly connected to the transmission rod 36 will approach each other until the clamping block 50 fixed on the top of the moving block 49 abuts against the jig body 23. At this time, the left and right sides of the jig body 23 can be clamped and fixed by the clamping blocks 50 to assist in fixing the jig body 23.

[0041] The structural design of the fixing mechanism realizes the function of facilitating the locking and fixing of the rotating rod 34. When the jig body 23 has not moved to the bottom of the clamping plate 40, the clamping column 43 will be locked and fixed with the clamping groove 42, thereby preventing the rotating rod 34 from rotating due to accidentally touching the knob 29. When the jig body 23 moves to the bottom of the clamping plate 40, the abutment block 48 fixed on the bottom end of the jig body 23 will abut against the top of the ejector rod 47 and push the ejector rod 47 downward to move. The ejector rod 47 is fixed on the top of the moving frame 46. At this time, the first springs 44 on both sides of the moving frame 46 will be When the movable frame 46 is compressed and moves downward, the post 43 fixed on the inner wall of the movable frame 46 will be pulled out of the slot 42, thereby releasing the engagement with the slot 42. At this time, the rotating rod 34 can be smoothly rotated by turning the knob 29. The knob 29 is turned in the opposite direction to ensure that the slot 42 opened on the bottom end of the rotating rod 34 is located directly above the post 43. At this time, when the jig body 23 is moved out from directly under the clamping plate 40, the first spring 44 will push the movable frame 46 upward to reset, and the post 43 will be reinserted into the slot 42, thereby completing the fixation of the rotating rod 34.

[0042] Through the structural design of the cleaning mechanism, the function of cleaning the surface of the light-transmitting plate 41 fixed on the pressing plate 40 is realized, so that the surface of the light-transmitting plate 41 can be kept clean, and the attachment of dust and debris to the light-transmitting plate 41 is reduced to avoid affecting the light transmittance of the light-transmitting plate 41. When the moving block 49 drives the clamping blocks 50 to approach each other, the inclined groove 53 provided on the clamping block 50 will push the sleeve block 54 to move to both sides, and the movable rod 55 fixed on the sleeve block 54 will slide on the retaining frame 57, and the second spring 56 will be compressed. When the sleeve block 54 moves to both sides, since the bottom end portion of the insertion rod 58 is inserted into the sleeve block 54, the sleeve block 54 can drive the insertion rod 58 to move, and the insertion rod 5 The top of 8 will slide on the slide rod 60, and the insertion rod 58 will drive the connecting piece 62 to move when it moves. The connecting piece 62 is rotatably connected with the brush tube 63, so it can drive the brush tube 63 to move. The brush tube 63 will clean the top of the light-transmitting plate 41 to reduce the adhesion of dust and debris on the light-transmitting plate 41. When the clamping blocks 50 are away from each other, the second spring 56 can reset the sleeve block 54, wherein the insertion rod 58 is rectangular in design and inserted in the sleeve block 54, and the sleeve block 54 is trapezoidal in design so as to abut against the inclined groove 53. The design of the notch 52 is so that when the insertion rod 58 moves downward together with the clamping plate 40, the insertion rod 58 can pass through the notch 52 to avoid abutting against the clamping block 50.

[0043] Furthermore, the abutment block 48 is designed to be trapezoidal, and the top end of the push rod 47 is provided with an inclined surface;

[0044] During operation, the abutment block 48 is trapezoidal in design and a slope is provided on the top of the push rod 47 so that the abutment block 48 can smoothly push the push rod 47 to move downward and reduce the wear when the push rod 47 and the abutment block 48 abut.

[0045] Furthermore, a rubber ring 30 is fixedly connected to the knob 29, and the rubber ring 30 is in contact with the front end of the processing platform 1;

[0046] During operation, the friction resistance in the process of rotating the knob 29 is increased by the contact between the rubber ring 30 and the processing platform 1. At the same time, the rubber ring 30 also serves to seal the knob 29 and the processing platform 1, so as to protect the stopper 31 inside the knob 29 and the limit block 32 fixed at the front end of the processing platform 1.

[0047] Furthermore, a stopper 31 is fixedly connected inside the knob 29, and the stopper 31 abuts against a group of limit blocks 32. Two groups of limit blocks 32 are provided, and the limit blocks 32 are fixedly connected to the front end of the processing platform 1;

[0048] During operation, the stopper 31 abuts against one of the groups of limit blocks 32. The design of the two groups of limit blocks 32 is convenient for limiting the rotation angle of the knob 29 to avoid excessive rotation of the knob 29, which may result in poor clamping effect of the clamping plate 40 on the jig body 23.

[0049] Embodiment 2

[0050] See also Figure 2 and Figure 4 As shown, comparative example 1 is another embodiment of the present invention, the fixing rod 45 is T-shaped, the moving frame 46 is rectangular, and the size of the card slot 42 is larger than the card column 43;

[0051] During operation, the fixing rod 45 is designed in a T-shape to reduce the upward vibration amplitude of the moving frame 46 when it is reset. The moving frame 46 is designed in a rectangular shape to avoid contact with the rotating rod 34. The size of the slot 42 is larger than the column 43, so that the column 43 can be smoothly inserted into the slot 42 to complete the fixation.

[0052] A round block 64 is fixedly connected to the top of the plug post 65, and the radius of the round block 64 is greater than the radius of the plug post 65;

[0053] During operation, the round block 64 is used to limit the maximum moving height of the pressing plate 40 on the plug post 65, ensuring that the pressing plate 40 will not be pulled upward and thus involve the rotating disk 38 and the connecting rod 39.
