DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Embodiment: A PCB drill bit milling cutter production cleaning device, such as Figure 1 and Figure 2 As shown, it includes an organism 1, a conveyor belt 2, an ultrasonic cleaning box 3, a guide rail 4, a slide 5, a synchronous transmission mechanism 6, a cylinder 7, a fixed frame 8, a screw transmission mechanism 9, a gate-shaped hook strip 10 and a placement basket 11. Conveyor belts 2 are provided on both sides of the left and right sides of the body 1. The middle part of the body 1 is fixedly connected to the ultrasonic cleaning box 3. The upper part of the body 1 is provided with a synchronous transmission mechanism 6. The top of the body 1 is fixedly connected to the guide rail 4 by bolts. The lower part of the guide rail 4 is slidably connected to the slide 5. The slide 5 is fixedly connected to the synchronous transmission mechanism 6. A plurality of cylinders 7 are fixedly connected to the bottom of the slide 5. The telescopic rod of the cylinder 7 is fixedly connected to the fixed frame 8. The fixed frame 8 is provided with a screw transmission mechanism 9. The lower part of the fixed frame 8 is slidably connected to two gate-shaped hook strips 10, and a placement basket 11 is hung at the bent hook of the gate-shaped hook strip 10.

[0022] like Figure 3 As shown, the synchronous transmission mechanism 6 includes a servo motor 6a, a synchronous wheel 6b, a rotating shaft 6c and a synchronous belt 6d. The servo motor 6a is installed on the upper front side of the body 1. Two synchronous wheels 6b are symmetrically connected to the front and rear sides of the upper part of the body 1 for rotation. A rotating shaft 6c is fixed between the two synchronous wheels 6b opposite to each other. The output shaft of the servo motor 6a is fixed to the rotating shaft 6c on the left side. The two synchronous belts 6d are respectively wound around the two synchronous wheels 6b on the same side. The upper parts of the two synchronous belts 6d are fixed to the bottom of the slide 5 by bolts. When the servo motor 6a and the synchronous wheel 6b drive the synchronous belt 6d to rotate, the slide 5 will move with the synchronous belt 6d.

[0023] like Figure 4As shown, the screw transmission mechanism 9 includes a screw stepper motor 9a, a bidirectional screw 9b and a guide rod 9c. The screw stepper motor 9a is installed at the bottom of the fixed frame 8. The output shaft of the screw stepper motor 9a is fixedly connected with the bidirectional screw 9b. The bidirectional screw 9b is threadedly connected to the upper ends of two gate-shaped hook strips 10. The guide rod 9c is symmetrically fixed to the bottom of the fixed frame 8. The guide rod 9c is slidingly connected to the upper ends of the two gate-shaped hook strips 10. When the screw stepper motor 9a drives the bidirectional screw 9b to rotate forward or reverse, the two gate-shaped hook strips 10 will approach or move away from each other.

[0024] like Figure 2 As shown, it also includes a cross bar 11a, and the cross bars 11a are symmetrically welded on the left and right sides of the placement basket 11. The outer side surface and the bottom surface of the placement basket 11 are both provided with dense holes, and the dense holes of the placement basket 11 facilitate liquid to enter the basket.

[0025] like Figure 2 As shown, it also includes a support plate 1a. The support plates 1a are provided on the left and right sides of the machine body 1. The top surfaces of the two support plates 1a are both provided with grooves. When the conveyor belt 2 conveys the placement basket 11 to the support plate 1a, the bottom of the placement basket 11 is in close contact with the edge of the groove, which can prevent the placement basket 11 from sliding or shifting, and ensure that when the door-shaped hook strip 10 moves to the top of the placement basket 11, the door-shaped hook strip 10 can accurately grasp and release the placement basket 11.

[0026] When in use, the slide 5 is located above the left support plate 1a, the ultrasonic cleaning box 3 is filled with cleaning liquid and is equipped with ultrasonic equipment, the drill bit to be cleaned is manually placed in the placement basket 11, and then the placement basket 11 is placed on the conveyor belt 2, and then the conveyor belt 2 will convey the placement basket 11 to the left support plate 1a, at this time, the cylinder 7 drives the fixing frame 8 and the gate-shaped hook strip 10 to move downward until the hook of the gate-shaped hook strip 10 is adjacent to the cross bar 11a of the placement basket 11, and the two-way screw rod 9b is driven to rotate by the screw rod stepping motor 9a to make the two gate-shaped hook strips 10 move in a direction close to each other until the hook of the gate-shaped hook strip 10 is in the placement basket. The cylinder 7 drives the fixing frame 8 and the gate-shaped hook strip 10 to move upward, so that the inner bottoms of the bent hooks of the two gate-shaped hook strips 10 are respectively in contact with the bottom of the cross bar 11a. At this time, the gate-shaped hook strip 10 continues to move upward, which will drive the placement basket 11 to move upward together, until the placement basket 11 is completely separated from the top surface of the support plate 1a, and then the servo motor 6a and the synchronous wheel 6b drive the synchronous belt 6d to rotate clockwise, and the synchronous belt 6d will drive the slide 5 to move rightward along the guide rail 4 until the gate-shaped hook strip 10 hangs the placement basket 11 and moves to the top of the ultrasonic cleaning box 3, and the fixing frame 8 and the placement basket 11 are driven downward by the cylinder 7. The ultrasonic cleaning box 3 moves until the cleaning liquid level in the ultrasonic cleaning box 3 submerges the placing basket 11, and the drill bit in the placing basket 11 is cleaned by the ultrasonic equipment in the ultrasonic cleaning box 3, which can effectively remove impurities in the small gap of the drill bit of the drill bit; after the cleaning of the drill bit is completed, the cylinder 7 drives the fixing frame 8 and the placing basket 11 to move upward until the bottom surface of the placing basket 11 is slightly higher than the conveyor belt 2 on the right, and then the servo motor 6a and the synchronous wheel 6b drive the synchronous belt 6d to rotate clockwise until the gate-shaped hook strip 10 hangs the placing basket 11 and moves it above the conveyor belt 2 on the right, and then the cylinder 7 drives the fixing frame 8 and the gate-shaped hook strip 10 to move downward, and the placing basket 11 After the bottom contacts the top surface of the conveyor belt 2, it stops moving, and the gate-shaped hook strip 10 continues to move downward until the bent hook of the gate-shaped hook strip 10 is adjacent to the cross bar 11a of the placement basket 11. At this time, the bidirectional screw rod 9b is driven by the screw stepper motor 9a to rotate in the opposite direction, so that the two gate-shaped hook strips 10 move away from each other, so that the gate-shaped hook strip 10 is completely separated from the placement basket 11. Thereafter, the fixed frame 8 and the gate-shaped hook strip 10 are driven by the cylinder 7 to move upward until the bottom height of the gate-shaped hook strip 10 is higher than the top of the placement basket 11, and then the placement basket 11 is transported to the support plate 1a on the right side through the conveyor belt 2, and the worker can proceed to the next process for the drill bit after cleaning.

[0027] like Figure 1 and Figure 5As shown, it also includes a hydraulic cylinder 12, a connecting frame 13 and a fan 14. The right sides of the front and rear sides of the machine body 1 are fixedly connected with hydraulic cylinders 12. The right side of the machine body 1 is slidably connected with a connecting frame 13. The connecting frame 13 is fixedly connected to the telescopic rods of the two hydraulic cylinders 12. A plurality of fans 14 are fixedly connected to the connecting frame 13. After the placing basket 11 is transported to the supporting plate 1a on the right side by the conveyor belt 2, the fan 14 is driven downward by the hydraulic cylinder 12 until the height of the fan 14 is slightly higher than the top of the placing basket 11. Since there is moisture remaining on the surface of the drill bit after cleaning, the drill bit is blown by the fan 14. The airflow generated by the fan 14 is directly blown to the drill bit, which accelerates the evaporation of moisture on the surface of the drill bit. The drill bit gradually becomes dry, thereby avoiding rusting of the drill bit and affecting the next process. After the drill bit is dried, the fan 14 is driven upward by the hydraulic cylinder 12 to reset.
