Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, and more specifically, to a drilling device for circuit board processing. Background Technology

[0002] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, and printed circuit boards. Circuit boards make circuits miniaturized and more intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layout.

[0003] In most existing circuit board drilling operations, the circuit board is placed on a fixing table and secured by tightening fixing screws. However, this method only secures the four opposite corners of the circuit board at a time, leaving the center unsupported. This not only leads to instability during drilling but also increases the risk of damage to the circuit board, resulting in low yield rates, and also limits the degree of adjustability. Therefore, a new drilling device for circuit board processing is proposed to solve these problems. Utility Model Content

[0004] To overcome the above-mentioned defects of the prior art, the present invention provides a drilling device for circuit board processing. The technical problem to be solved by the present invention is that when most existing circuit boards need to be fixed during drilling operations, the circuit board is placed on a fixed platform and then fixed by turning the fixing screws. Each time, only the four corners of the circuit board are fixed, but the center of the circuit board is not supported. This not only easily causes unstable drilling, but also damages the circuit board during drilling, resulting in a low yield rate, and the ability to freely adjust is not high enough.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a drilling device for circuit board processing, comprising a support assembly, wherein a plurality of load-bearing components are provided on the top of the support assembly, and a plurality of clamping components are provided on the top of the support assembly;

[0006] The load-bearing component includes a square tube, with multiple inserts fixedly connected to the bottom of the square tube, multiple locking posts penetrating the surface of the square tube, a square column inside the square tube, multiple locking slots penetrating the surface of the square column, a connecting block fixedly connected to the top of the square column, a slot on the top of the connecting block, a positioning plate fixedly connected to the top of the connecting block, and multiple positioning grooves on the surface of the positioning plate.

[0007] In a preferred embodiment, the support assembly includes a base plate with a sliding groove on its top, a T-shaped groove running through its side, locking grooves on both sides of the base plate, multiple positioning holes on its top, and locking plates within each locking groove. A vertical block is fixedly connected to one side of the base plate, and multiple fixed blocks are fixedly connected to the top of the vertical block. A stud is running through the surface of each of the fixed blocks. A motor is fixedly connected to one side of the stud, and a slider is fitted onto the surface of the stud. A horizontal bar is fixedly connected to one side of the slider, and a slide rail is running through the surface of the horizontal bar. A second motor is fixedly connected to one side of the horizontal bar, and a second stud is fixedly connected to the output end of the second motor. A second slider is fitted onto the surface of the second stud, a drill bit is fixedly connected to the bottom of the second slider, and a T-shaped column is fixedly connected to the top of the second slider. A sliding column is fixedly connected within the sliding groove, and a long block is fixedly connected within the T-shaped groove. A sliding strip is fitted onto the surface of the sliding column.

[0008] In a preferred embodiment, the clamping assembly includes a square tube II with multiple through holes extending through its bottom. Multiple L-plates are fixedly connected to the bottom of the square tube II. Locks are provided at the top of the multiple through holes. Multiple locking pins II are provided through the surface of the square tube II. A square post II is provided within the inner cavity of the square tube II. Multiple locking slots II are provided through the surface of the square post II. A connecting block II is fixedly connected to the top of the square post II. A top block is fixedly connected to the top of the connecting block II. A locking knob is rotatably connected to one side of the top block. A rotating post is provided through the surface of the top block. A clamping block is sleeved on one end of the rotating post. Multiple clamping plates are fixedly connected to one side of the clamping block. A connecting groove is provided at the center of one side of the clamping block. A collar is provided within the connecting groove. A locking bolt is fixedly connected to the side of the collar away from the rotating post. A baffle is provided on one side of the square tube II.

[0009] In a preferred embodiment, the outer diameter of the first insertion post is the same as the inner diameter of the positioning hole, the inner diameter of the positioning groove is different from the outer diameter of the drill bit, and the number of the load-bearing components can be adjusted according to the usage scenario. In later use, stability can be achieved by inserting the first insertion post at the bottom of the load-bearing component into the positioning hole, and the positioning plate at the top can support the circuit board. When the drill bit penetrates the circuit board, the positioning groove prevents the positioning plate from blocking the drill bit, thus avoiding the problem of double damage to the drill bit and the positioning plate.

[0010] In a preferred embodiment, the motor is connected not only to the stud but also to a single fixed block. The slide bar is fixedly connected to the bottom of one end of the crossbar. Lubricating oil is provided in the slide groove. A telescopic cylinder is provided between the slider and the drill bit. In later use, the motor and the stud drive the slider to slide with the crossbar and the slide bar. Since the slide post sleeved at the bottom of the slide bar is not a threaded rotating device, the lubricating oil in the slide groove makes the sliding of the slide post and the slide bar smoother, avoiding jamming that would affect the use of the equipment.

[0011] In a preferred embodiment, the bottom of each latch is provided with multiple insertion pins, the outer diameter of which is consistent with the outer diameter of the through hole and the positioning hole. The locking pin penetrates the top block and contacts the rotating pin. A spring is sleeved on the surface of the rotating pin. The surface of the clamping plate is made of silicone material. The latch contacts the baffle. In later use, when the clamping plate clamps the circuit board, the softness of the silicone material avoids damage to the surface of the circuit board. When drilling, the spring can also distribute the vibration during drilling, making the device more stable during drilling and improving the pass rate.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] 1. This utility model, by incorporating a support assembly and a load-bearing assembly, allows for direct adjustment of the drill bit's rotation position via control of motors one and two. During drilling, the load-bearing assembly at the bottom of the circuit board prevents the center of the circuit board from lacking support, which could lead to unstable drilling and circuit board damage, resulting in a low yield. This improves the processing success rate of the device.

[0014] 2. This utility model, by providing a load-bearing component and a clamping component, can be adjusted in later use by means of square tube one, insert one, square tube two, and square column two, thereby improving the adjustment capability of the device. Furthermore, by using the load-bearing component and the clamping component to clamp and support the bottom and sides of the circuit board, the stability during processing is improved.

[0026] The bottom of the latch 34 is provided with multiple insertion pins 22. The outer diameter of the insertion pin 22 is the same as the outer diameter of the through hole 32 and the positioning hole 15. The locking knob 310 penetrates the top block 39 and contacts the rotating pin 311. A spring is sleeved on the surface of the rotating pin 311. The surface of the clamping plate 313 is made of silicone. The latch 34 contacts the baffle 317.
