Description

Technical Field

[0001] This utility model relates to the field of circuit board processing, and specifically to a circuit board drill bit cleaning device. Background Technology

[0002] Circuit boards (PCBs) are the support structure for electronic components and the carrier for electrical connections between them, making them an indispensable part of electronic devices. Common PCB types include single-sided, double-sided, and multilayer boards. The manufacturing process of PCBs involves steps such as material preparation, drilling, circuit pattern creation, copper plating, circuit fabrication, etching, AOI (Automated Optical Inspection), and silkscreen printing. Drilling is used to create vias in PCBs. Vias are channels connecting circuits between different layers. Vias are typically created by first drilling holes in the substrate. In subsequent processes such as electroplating, a conductive copper film forms on the hole walls, enabling electrical connections between the different layers. PCB vias are generally created using drilling equipment. The PCB substrate is fixed to the drilling equipment, which drills holes at predetermined locations according to pre-defined drilling data. PCB drill bits need to be cleaned before use after production. Furthermore, over time, various stains inevitably accumulate on the surface of the drill bits. If these stains accumulate, they may affect the drilling results; therefore, cleaning is necessary after a certain period of use. When cleaning circuit board drill bits, the drill bits are usually placed in a water tank for cleaning, and then rinsed with water or brushed with tools. Although ultrasonic cleaning is now available, it still requires manual labor to put the circuit board drill bits into and take them out of the cleaning unit, which is quite labor-intensive.

[0020] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0021] Refer to 1 to Figure 3 This utility model provides a circuit board drill bit cleaning device, including a base 1, a cleaning mechanism 2 disposed on the base 1, a feeding conveying mechanism 3 disposed on one side of the cleaning mechanism 2, a discharging conveying mechanism 4 disposed on the opposite side of the cleaning mechanism 2, a material rack 5 for placing drill bits, and a conveying mechanism 6 disposed on the base 1 for moving the material rack 5 between the feeding conveying mechanism 3, the cleaning mechanism 2, and the discharging conveying mechanism 4. Both the feeding conveying mechanism 3 and the discharging conveying mechanism 4 include a conveying bracket and a conveyor belt disposed on the conveying bracket. The feeding conveying mechanism 3 can convey the material rack 5 containing the drill bits to be cleaned to the cleaning mechanism 2. The conveying mechanism 6 picks up the material rack 5 from the feeding conveying mechanism 3, moves the material rack 5 to the cleaning mechanism 2 for cleaning, and after cleaning, transfers the material rack 5 to the discharging conveying mechanism 4, which then sends the material rack to the next workstation. A positioning structure can be provided on the feeding conveying mechanism 3 to block the material rack 5 at a set position, thereby facilitating the conveying mechanism 6 to pick up the material rack 5.

[0022] The material rack includes a storage base 51 and two handles 52 respectively disposed on both sides of the top surface of the storage base 51. The storage base 51 is evenly provided with a plurality of placement parts 53 for placing drill bits. In a specific implementation, a drainage hole can be provided at the bottom of the placement part 53 so that when the material rack is lifted after cleaning, water can flow out through the drainage hole, thus preventing water accumulation on the material rack.

[0023] The conveying mechanism 6 includes a conveying support frame 61 mounted on the base 1, a horizontal drive module 62 mounted on the conveying support frame 61, a movable plate 63 connected to the horizontal drive module 62, a lifting assembly 64 connected to the movable plate 63, and two conveying assemblies 65 connected to the lifting assembly 64, the two conveying assemblies 65 being symmetrically arranged. The horizontal drive module 62 can be an electric lead screw module, thereby enabling precise control of the position of the lifting assembly 64.

[0024] The conveying assembly 65 includes a pull rod 651 rotatably connected to the lifting assembly 64, and a conveying drive component 652 connected to the lifting assembly 64 for driving the pull rod 651 to rotate. A conveying hook 653 is provided at the lower end of the pull rod 651, and the output end of the conveying drive component 652 is rotatably connected to the upper end of the pull rod 651. In this embodiment, the conveying drive component 652 is a cylinder. Figure 2 Taking the perspective as an example, when the lifting assembly 64 descends to the point where the transport hook 653 is lower than the handle 52 of the material rack, when the cylinder piston rod extends, the upper end of the pull rod 651 rotates to the left, that is, the pull rod 651 rotates counterclockwise. At this time, the lower end of the transport hook 653 rotates to the right and enters below the handle 52. Then the lifting assembly 64 moves upward, and the transport hook 653 hooks the handle 52, lifting the material rack.

[0025] The lifting assembly 64 includes a first lifting bracket 641 connected to the movable plate 63, a second lifting bracket 642 movably connected to the first lifting bracket 641, a fixed plate 643 connected to the second lifting bracket 642, and a lifting drive component 644 disposed on the first lifting bracket 641 for driving the second lifting bracket 642 to move vertically. The pull rod 651 and the fixed plate 643 are rotatably connected, and the lifting drive component 644 is disposed on the fixed plate 643. The lifting drive component 644 can be a cylinder, hydraulic cylinder, electric cylinder, or electric screw module. It should be noted that if a cylinder or hydraulic cylinder is used, a solenoid valve needs to be installed to control the flow rate of the medium in order to control the stroke. Of course, the stroke of the cylinder or hydraulic cylinder can also be adapted by adjusting the height of the feeding conveying mechanism 3 and the discharging conveying mechanism 4.

[0026] The cleaning mechanism 2 includes a water tank 21, a pool body 22 disposed inside the water tank 21, and a plurality of ultrasonic generators 23 disposed on the bottom surface of the pool body 22. After the material rack 5 enters the pool body 22, the ultrasonic generators 23 generate ultrasonic waves, which can clean the drill bit.

[0027] The bottom surface of the pool body 22 is a slope, and a drain outlet 24 is provided on the side wall of the pool body 22 at the lowest point of the slope.

[0028] The circuit board drill bit cleaning device also includes a water circulation mechanism 7. The water circulation mechanism 7 includes a circulating water tank 71 mounted on the base 1, a filter tank 72 connected to the circulating water tank 71, a first water pipe 73, and a second water pipe 74. One end of the first water pipe 73 is connected to the filter tank 72, and the other end is connected to the cleaning mechanism 2. One end of the second water pipe 74 is connected to the circulating water tank 71, and the other end is connected to the cleaning mechanism 2. In practice, both the first water pipe 73 and the second water pipe 74 are connected to water pumps for easy water delivery. The water circulation mechanism 7 can filter wastewater and then return the filtered water to the cleaning mechanism 2 for reuse, making the overall system more environmentally friendly.

[0029] The circulating water tank 71 is internally divided into a sedimentation tank 711 and a clear water tank 712 by a partition. The filter tank 72 is connected to the sedimentation tank 711, and the second water pipe 74 is connected to the bottom of the clear water tank 712. The first water pipe 73 draws sewage from the tank body 22 and transports it to the filter tank 72. After the filter tank 72 filters the sewage, the water is discharged into the sedimentation tank 711. After the sedimentation tank 711 is full, the water overflows from the top into the clear water tank 712. Then, the second water pipe 74 transports the clear water from the clear water tank 712 back to the tank body 22 for reuse. Alternatively, in a specific implementation, a filter roller can be installed inside the circulating water tank 71. The water from the filter tank 72 is discharged into the filter roller for secondary filtration before entering the sedimentation tank 711 to enhance the filtration effect.

[0030] In actual operation, the feeding conveyor 3 conveys the material rack 5 containing the drill bits to be cleaned. The lifting mechanism moves to the feeding conveyor 3 under the drive of the horizontal drive module 62 and picks up the material rack 5. Then, the material rack 5 is placed into the pool 22 of the cleaning mechanism 2 for ultrasonic cleaning. After cleaning, the material rack 5 is transferred to the discharge conveyor 4 and put down. Then, the discharge conveyor 4 conveys the material rack 5 to the next station, such as the drying station for drying.

[0031] The conveying mechanism 6 of this utility model includes a horizontal drive module 62, a lifting component 64, and a conveying component 65. After the feeding conveying mechanism 3 grabs the material rack 5, it is placed into the cleaning mechanism 2 for cleaning. After cleaning, the material rack 5 is transferred to the discharge conveying mechanism 4. The entire cleaning process is basically automated, requiring no manual intervention, reducing labor intensity, improving work efficiency, and saving production costs.
