Description

Technical Field

[0001] The invention relates to the technical field of circuit board manufacturing, in particular to circuit board manufacturing processing equipment. Background Art

[0002] PCB circuit board, Chinese name is printed circuit board, is the carrier of electrical connection of electronic components. When processing PCB circuit board, in order to reduce damage and improve processing efficiency, multiple sets of circuit boards are often processed on the same substrate. After processing, the electronic components are separated by a board separator. V-CUT is a V-shaped groove. The so-called V-CUT is a strip of dividing tape that is cut in advance at a specific position of the PCB by a turntable tool according to the customer's drawing requirements by the printed circuit board (PCB) manufacturer. Its purpose is to facilitate the separation of subsequent SMT circuit boards after assembly. When in use, the V-CUT groove of the PCB to be separated is stuck on the lower knife blade within the upper knife stroke, and the board separation operation is performed by stepping on the foot switch.

[0003] Before using the panel splitter for cutting, the panel needs to be positioned on the processing platform. In the prior art, a clamp is generally required to limit and fix the panel. Therefore, a lot of time and effort is required to position and align the circuit board, resulting in low processing efficiency. In addition, the existing knife-feeding panel splitter needs to separate the dividing belt with a V-groove from the single board on the panel when used. Therefore, it is necessary to cut the dividing belt first and then cut the single board, and repeat this process until the panel splitting operation is completed. During this process, the cutting line needs a complete reciprocating stroke to cut off, and the cut dividing belt is often mixed with the single board when discharged. Later, it is necessary to manually sort the two, which is cumbersome.

[0004] Therefore, in view of this, research and improvement are conducted to the existing structural deficiencies, and circuit board manufacturing and processing equipment is proposed. Summary of the invention

[0010] Furthermore, a sliding cutting assembly is provided inside the gantry, and the sliding cutting assembly includes a machine body, a threaded block, a cross block and a guide rod.

[0012] Furthermore, the sliding cutting assembly also includes a sleeve rod, an upper circular knife and a fastening pin. The sleeve rod is fixed at the front and rear ends of the cross block, and the upper circular knife is sleeved on the outside of the sleeve rod. The upper circular knife and the lower straight knife on both sides cooperate to achieve synchronous cutting of adjacent V-grooves of the PCB board, and the upper circular knife is fastened to the sleeve rod through the fastening pin.

[0013] Furthermore, automatic material dividing components are symmetrically arranged on both sides of the bottom of the machine body, and the automatic material dividing components include a slide seat, a connecting rod and a triangular pin. The slide seat is fixed to the middle end of the bottom of the machine body, and a connecting rod slides inside the slide seat.

[0016] The present invention provides a circuit board manufacturing and processing device, which has the following beneficial effects:

[0017] 1. During the use of the present invention, the panel is placed on the feed belt and transported toward the lower straight knife in the middle of the workbench. When it is at the end of the feed belt, the two cylinders at the outer sides of the side plate are synchronously started to pull the pressure plate down. The application designs the pressure plate as a "U"-shaped structure with rubber blocks at both ends and a hollow avoidance groove in the middle. First, the bottom conical surface of the driving block at the rear end of the avoidance groove opening is squeezed and matched with the top inclined surface of the driven block, driving the driven blocks on both sides to slide toward each other synchronously, thereby realizing the centering of the panel. Secondly, the rubber blocks on both sides of the pressure plate are used to press the side edges of the panel to avoid displacement of the panel caused by the upper circular knife during rolling cutting. The application uses the setting of a centering positioning component to position and align the panel without manual intervention, thereby significantly improving production efficiency through automated operations.

[0018] 2. During the use of the present invention, firstly, the lateral displacement of the threaded block at the opposite surface of the top of the gantry is controlled by the thread cooperation between the lead screw at the output end of the motor and the thread of the threaded block, and the linear rolling cutting operation of the upper circular knife is completed accordingly. Secondly, the hand wheel is shaken and the threaded rod is rotated and transmitted through the gear set, and the vertical spacing between the upper circular knives on both sides and the lower straight knife at the bottom is controlled by the thread cooperation between the threaded rod and the thread of the cross block to adapt to the cutting and dividing of circuit boards of different thicknesses. Finally, the upper circular knives on both sides are assembled on the sleeve rods at the front and rear ends of the cross block and fixed by fastening pins. The spacing between the upper circular knives on both sides can be adjusted by adding or reducing gaskets to adapt to the cutting requirements of dividing strips of different widths. Compared with the operation mode of the knife-type board dividing machine in the prior art, which requires a complete round trip stroke to cut the dividing strip, the present application uses the structural design of double upper circular knives, and only needs a single stroke to complete the cutting operation of the dividing strip, effectively improving the board dividing efficiency of the circuit board, and the upper circular knives on both sides can be regulated in three axes, with a wider operating surface, which can adapt to the board dividing requirements of different types of puzzle boards.

[0019] 3. During the use of the present invention, push plates are symmetrically arranged at the two ends of the bottom of the sliding cutting component. In this way, when the upper circular knives on both sides complete the cutting operation of the dividing strip, the push plates following closely behind will push the cut dividing strip away from the upper surface of the lower straight knife and drop it into the material frame, and the separated single board will fall into the discharge belt under the guiding action of the inclined surface of the guide plate. When the sliding cutting component is at the end of a single stroke, the trigger block on the inner side of the gantry will conflict with the connecting rod, so that the triangular pin at one end of the connecting rod is inserted into the through hole of the corresponding adjusting rod, so that the push plate at the front end of the next stroke direction is retracted back into the sleeve, preventing the push plate at the front end of the stroke in the reciprocating stroke from causing motion interference with the lower straight knife. Through the setting of the automatic sorting component, the single board and the dividing strip can be classified and unloaded during the cutting process, and the subsequent sorting procedures can be simplified to improve production efficiency.
