Description

Technical Field

[0001] This utility model relates to the field of circuit board cutting technology, and in particular to a rapid circuit board cutting device. Background Technology

[0002] Circuit boards are an indispensable component of modern electronic devices. Their manufacturing process involves multiple steps, including cutting, drilling, printing, and assembly. Among these steps, cutting is a crucial one, as it determines the size and shape of the circuit board.

[0003] Currently, circuit board cutting mainly involves dividing the circuit board into sections for longitudinal and transverse cutting after the overall circuit board production is completed. According to the authorized publication number "CN207747127U", a circuit board cutting device is disclosed, comprising: an optical detection device for detecting a first cutting line on the circuit board mother sheet; an adjustment component for adjusting the circuit board mother sheet to the cutting position based on the detection result of the optical detection device; and a first cutting component for cutting the circuit board mother sheet into multiple circuit boards aligned with the first cutting line. The cutting position is defined as the position where the extension direction of the first cutting line on the circuit board mother sheet is parallel to the extension direction of the first cutting component. Therefore, this circuit board cutting device eliminates the need for manual labor to cut the circuit board mother sheet, effectively solving the problems of difficulty in cutting at high temperatures or even burns to personnel when cutting circuit board mother sheets manually, or the potential for accidental scratches and damage to the circuit boards caused by using blades, thus reducing the yield rate.

[0004] Currently, when cutting circuit boards, the board needs to be placed on a platform and cut longitudinally and laterally by contacting the rotating cutting disc. However, most platforms cannot adjust their height as needed, which limits the flexibility of cutting. This forces operators to frequently change tools or adjust equipment parameters when cutting circuit boards of different thicknesses. Secondly, existing circuit board cutting equipment lacks an effective positioning and limiting mechanism. During the cutting process, the circuit board may move due to improper operation or equipment failure, resulting in offset cutting position or incomplete cutting. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned shortcomings in the existing technology by proposing a rapid circuit board cutting device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a circuit board rapid cutting device, including a worktable, a slide rail fixedly installed at the upper end of the worktable, the slide rail having a T-shaped cross-section, a slide seat slidably attached to the surface of the slide rail, cylinders arranged side by side fixedly distributed at the upper end of the slide seat, piston rods for extension and retraction being provided inside the cylinders, and the ends of several piston rods being jointly installed on the same platform, a cutting groove being provided in the middle of the platform; A support frame is fixedly installed at the upper end of the workbench. The horizontal position of the support frame is parallel to and corresponds to the slide rail. A bushing is fixedly installed through both sides of the support frame. The same drive shaft is installed through the two bushings distributed along both sides. A cutting disc is fixedly sleeved on the surface of the drive shaft. The cutting disc is vertically aligned with the cutting groove. A motor is installed at the outer end of the drive shaft. The outer ring wall of the motor is fixedly installed to the surface of the workbench through a bracket. A rotating shaft for driving is installed inside the motor. The end of the rotating shaft is fixedly installed to the drive shaft through a coupling.

[0007] Preferably, the inner two ends of the slide are symmetrically distributed and fixed with bearing seats, and the bearing seats are rotatably sleeved with rollers.

[0008] Preferably, a support roller is fixedly sleeved on the surface of the roller shaft, and several groups of support rollers are arranged side by side along the front and rear positions of the slide block, with the outer ring wall of the support roller rolling against the surface of the slide.

[0009] Preferably, the platform has inner cavities on both sides, and bearings are fixed through both sides of the inner wall of the inner cavity.

[0010] Preferably, the two bearings distributed along both sides are internally connected by the same shaft, the surface of the shaft is interference-fitted with the inner ring wall of either bearing, and a crank handle is fixedly installed at the outer end of the shaft.

[0011] Preferably, the shaft has symmetrically distributed external threads on its surface, and a threaded sleeve is installed on the surface of the external threads.

[0012] Preferably, a limiting rod is fixedly installed on the upper end of the outer ring wall of the threaded sleeve, and a limiting hole is opened at the upper end of the inner cavity, which penetrates the inner cavity. The limiting rod is slidably fitted with the limiting hole, and a limiting plate is fixedly installed on one side of the limiting rod.

[0013] The design scheme proposed in this utility model has the following beneficial effects in application: 1. This solution, through the coordinated design of the slide rail and the slide base, can ensure that the circuit board moves stably during the cutting process. The support roller at the bottom of the slide base rolls in contact with the surface of the slide rail, effectively reducing frictional resistance and making it easier and smoother for the operator to manually push the circuit board. At the same time, the height of the table can be adjusted by the cylinder to accommodate circuit boards of different thicknesses or types, ensuring consistent cutting depth and improving cutting accuracy and ease of operation. 2. This solution employs an adjustable limiting mechanism. By rotating the crank-driven shaft, the symmetrically distributed limiting plates move synchronously in opposite directions, thereby quickly adjusting the clamping distance. This design ensures that circuit boards of different sizes can be firmly fixed, preventing offset or vibration during cutting. The sliding fit between the limiting rod and the limiting hole ensures the stability of the movement process, further enhancing the accuracy of the cutting position and improving processing quality and efficiency.

The cutting groove 15 can cooperate with the cutting disc 19 to achieve spatial fit during the cutting process. The extension and retraction of the piston rod of the cylinder 13 can realize the height adjustment of the platform 14. A support frame 16 is fixedly installed on the upper end of the worktable 1. The horizontal position of the support frame 16 is parallel to and corresponds to the slide rail 11. Both sides of the support frame 16 are fixedly fitted with bushings 17.

The outer ring wall of the motor 110 is fixedly installed on the surface of the worktable 1 through a bracket. The motor 110 has a rotating shaft for driving inside. The end of the rotating shaft is fixedly installed at the connection position with the drive shaft 18 through a coupling. When cutting is required, the power supply of the motor 110 is turned on, so that the motor 110 can drive the rotating shaft and cause the drive shaft 18 to move in conjunction, thereby stabilizing the cutting disc 19.

[0018] Among them, the inner two ends of the slide 12 are symmetrically fixed with bearing seats 2, and the roller shaft 21 is rotatably sleeved inside the bearing seat 2, and the roller shaft 21 can rotate stably based on the bearing seat 2.

[0019] Among them, a support roller 22 is fixedly sleeved on the surface of the roller shaft 21. Several groups of support rollers 22 are arranged side by side along the front and rear positions of the slide block 12. The outer ring wall of the support roller 22 is rolled on the surface of the slide rail 11. The support roller 22 can play a sliding support effect when the slide block 12 slides based on the slide rail 11, thereby making the movement of the slide block 12 smoother.

[0020] The platform 14 has an inner cavity 37 on both sides, and a bearing 3 is fixed through both sides of the inner wall of the inner cavity 37. The bearing 3 allows the shaft 31 to be stably and rotatably installed inside the inner cavity 37.

When it is necessary to adjust the distance between the two symmetrically distributed limiting plates 36, the shaft 31 is rotated by the crank 30, so that the external thread 32 on the shaft 31 rotates synchronously. Through the symmetrical arrangement of the two external threads 32 and the sliding of the limiting rod 34 inside the limiting hole 35, the two limiting plates 36 can move closer or further away from each other at the same time.
