Description

Technical Field

[0001] This utility model belongs to the field of circuit board processing technology, specifically relating to a PCB circuit board processing drilling device. Background Technology

[0002] PCB circuit boards are the basic carriers in electronic products used to carry electronic components and realize their electrical connections. By etching conductive copper foil on an insulating substrate to form circuit lines, they provide a platform for fixing, supporting and transmitting signals for components. The drilling equipment used in the manufacturing process is mainly to drill through holes, blind holes or buried holes of different specifications to realize electrical conduction between the copper foil lines of different layers of the circuit board, to provide channels for the insertion and fixing of component pins, and to meet the functional requirements of positioning and heat dissipation during later assembly. It is a key process to ensure the integrity and practicality of PCB circuits.

[0003] However, existing drilling devices lack a positioning mechanism for the circuit board, which can easily cause the circuit board to shift during drilling. This shift can lead to deviations in the hole position, uneven hole diameter, and rough hole walls, thus affecting the accuracy and quality of drilling and consequently having an adverse impact on subsequent circuit assembly and equipment performance. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this utility model provides a PCB circuit board processing drilling device to solve the problems in the prior art.

The positioning component includes a slide rail assembly fixedly connected to the top of the worktable, with two positioning plates slidably connected to the outer surface of the slide rail assembly. A PCB circuit board is disposed on the top of the worktable, and a slide rail is fixedly connected to the top of the worktable. A slider is slidably connected to the outer surface of the slide rail, and two connecting rods are hinged to the top of the slider. The ends of the two connecting rods away from the slider are hinged to the two positioning plates. A driving component is disposed on the worktable, wherein the sides of the two positioning plates that are close to each other are in contact with the PCB circuit board.

[0006] Preferably, the adjustment unit includes an adjustment component disposed at the bottom of the worktable, and a balancing component disposed on the adjustment component, wherein the adjustment component is used in conjunction with the balancing component.

[0007] Preferably, the drilling assembly includes a support rod group fixedly connected to the top of the workbench. A sliding groove is provided on the support rod group, and a second slider is slidably connected to the inner wall of the sliding groove. A motor sleeve is fixedly connected to the bottom of the second slider, and a first motor is fitted onto the inner wall of the motor sleeve. A drill bit is fixedly connected to the output shaft of the first motor via a coupling. A second hydraulic push rod is fixedly connected to the top of the second slider, and the output end of the second hydraulic push rod is fixedly connected to the motor sleeve. A second driving component is provided on the support rod group, wherein the output end of the second hydraulic push rod passes through the second slider and is slidably connected to it. The horizontal position adjustment of the drill bit is achieved through the cooperation of the sliding groove and the second slider. The vertical lifting and lowering of the drill bit is achieved by driving the motor sleeve and the drill bit with the second hydraulic push rod. This bidirectional adjustment mechanism makes the drilling operation more flexible and precise, adapting to different drilling position requirements. Simultaneously, the connections of each component are stable, the transmission structure is clear, and the practicality and ease of operation of the drilling assembly are improved.

[0008] Preferably, the collection component includes several drain holes on the top of the workbench, and a collection box is slidably connected to the bottom of the workbench. The drain holes are all connected to the collection box, and the processing waste on the workbench can automatically fall into the collection box through the drain holes, eliminating the need for frequent manual cleaning. The slidably connected collection box is easy to disassemble and install, and the waste can be pulled out and dumped at any time. The operation is simple and efficient, and the overall structure is concise. It not only achieves centralized collection of waste, but also avoids the accumulation of waste from affecting processing accuracy, thereby improving work efficiency and the cleanliness of the workbench.

[0009] Preferably, the adjustment assembly includes a base plate disposed at the bottom of the workbench, a rectangular frame fixedly connected to the top of the base plate, a second motor fixedly connected to the left side of the rectangular frame, and a rotating shaft fixedly connected to the output shaft of the second motor via a coupling. A transmission component is disposed on the outer wall of the rotating shaft, wherein the rotating shaft passes through the rectangular frame and is rotatably connected to the rectangular frame. The rotating shaft is driven to rotate by the second motor, and the power is transmitted to other components by the transmission component to realize the adjustment of the relevant functions of the workbench. The rectangular frame provides stable support for the rotating shaft, ensuring the stability and reliability of the transmission process. The overall structure is compact, occupies little space, and the base plate at the bottom facilitates integration with other components, improving the overall performance and adjustment flexibility of the equipment.

[0010] Preferably, the balancing assembly includes several sleeves fixedly connected to the bottom of the base plate, with balance rods slidably connected to the inner walls of each sleeve, and the top ends of each balance rod fixedly connected to the worktable. Four sleeves and four balance rods are provided, and the four evenly distributed sleeves and balance rods form a stable support structure. When the worktable moves or experiences uneven force, the balance rods can slide freely within the sleeves to dynamically adjust the support height, effectively counteracting tilting torque and preventing the worktable from shaking or tilting due to uneven force, thus ensuring machining accuracy.

[0011] Preferably, the driving component includes a rectangular plate fixedly connected to the back of the worktable, and a hydraulic push rod is fixedly connected to the back of the rectangular plate.

The output end of the hydraulic push rod three is fixedly connected to the second slider. The hydraulic push rod three is located on the right side of the second slider. The extension and retraction of the hydraulic push rod three directly drives the second slider to slide in the groove, thereby achieving precise adjustment of the horizontal position of the drill bit. The hydraulic push rod three arranged on the right side makes the direction of the thrust consistent with the sliding direction of the second slider, avoiding jamming or wear caused by lateral force and improving transmission efficiency.

[0013] Preferably, the transmission component includes a second connecting rod sleeved on the outer wall of the rotating shaft, a third connecting rod hinged to the end of the second connecting rod away from the rotating shaft, and a fixed frame hinged to the end of the third connecting rod away from the second connecting rod. The top of the fixed frame is fixedly connected to the worktable. The rotating shaft is driven to rotate by the second motor, which drives the second connecting rod to perform a circular motion. The third connecting rod then converts the circular motion into a linear reciprocating motion of the fixed frame, thereby achieving horizontal adjustment of the worktable. The hinged structure allows each rod to freely adjust its angle during movement, effectively buffering the impact force during the transmission process, reducing rigid collisions and wear, and extending the service life of the components.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: 1. By setting up a positioning part, when in use, first place the PCB circuit board to be drilled on the top of the workbench. After starting the hydraulic push rod, it drives the two hinged connecting rods to move forward along the slide rail through the slider. With the help of the hinged transmission between the connecting rod and the two positioning plates on the slide rail group, the two positioning plates move closer to each other, thereby positioning and fixing the PCB circuit board to prevent it from shifting during drilling and to ensure accuracy and quality. 2. By setting an adjustment section, when the height of the device needs to be adjusted during use, motor two can be started. It drives connecting rod two to rotate through the shaft. With the hinge transmission between connecting rod two and connecting rod three, and the hinge cooperation between connecting rod three and the fixed frame at the bottom of the worktable, the worktable at the top of the fixed frame can be smoothly adjusted to a suitable height to meet the height requirements of different scenarios. At the same time, when the worktable is raised and lowered, multiple balance bars at its bottom will slide synchronously in the sleeve at the top of the base plate. This design greatly enhances the stability of the raising and lowering, ensuring that the device always operates stably during the adjustment process. Attached Figure Description
