Description

Technical Field

[0001] The utility model relates to the field of PCB boards, in particular to a board splitting fixture and a board splitting machine. Background Art

[0002] The PCB board, also known as the printed circuit board, is widely used in various different electronic devices. As the last process of PCB board processing, board splitting is to cut a continuous and large-area PCB board into multiple independent and small-area PCB boards according to specific size and shape requirements. There are gaps between adjacent small-area PCB boards on the large-area PCB board, and they are connected at a certain point in the gap. Board splitting is to cut this connection point. The traditional board splitting process uses the manual folding method. However, strong stress will be generated during manual folding, which will seriously affect the product quality. With the development of technology, manual folding has basically been replaced by machine board splitting. Since the connection points to be cut between adjacent small-area PCB boards are usually small, the existing board splitting fixtures only fix the large-area PCB board to be split, and the splitting points between small-area PCB boards cannot be clearly exposed under the board splitting machine. When the existing board splitting machine performs board splitting, it is easy to cut the traces incorrectly due to unclear cutting points, resulting in the circuit being cut off, and the cutting efficiency and accuracy are not high. Content of the Utility Model

[0003] In view of the existing deficiencies, the utility model provides a board splitting fixture and a board splitting machine.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a board splitting fixture, including a base, a square base groove is arranged on the top surface of the base, light sources are arranged on the inner surfaces of the four groove walls of the base groove, an installation mechanism for installing a PCB board is arranged at the open end of the base groove, and the light emitted by the light source makes a brightness difference at the position to be cut on the PCB board, and a control switch for controlling the light source is arranged on the base.

[0005] Preferably, a grid-shaped bottom through hole is arranged at the bottom of the base groove, and a baffle covering the bottom through hole is erected on the bottom of the base groove.

[0006] Preferably, the installation mechanism is a step recessed at the open end of the base groove and surrounding the inner wall of the base groove.

[0007] Preferably, the installation mechanism includes a cover plate covering the open end of the base groove, a countersunk cover plate through hole arranged in the middle of the cover plate or a cover plate groove with a light-transmitting through hole at the countersunk bottom of the cover plate groove.

[0008] Preferably, the light source is an LED lamp.

[0009] Preferably, side wall grooves or side wall through holes for installing light sources are provided on the inner surfaces of the four side walls of the base groove.

[0010] Preferably, a plurality of light sources are provided on the side wall of each base groove.

[0011] A circuit board splitting machine adopts the circuit board splitting fixture described in any one of the above.

[0012] The beneficial effects of the present utility model are as follows: The utility model uses the light emitted by the light source in the base groove to irradiate the bottom of a large-area circuit board to be cut. When the light irradiates the gap between small-area circuit boards, the light will penetrate to enhance the brightness at this place. When the light irradiates the cutting point to be cut between small-area circuit boards, the cutting point to be cut will block the emission of light. In this way, the brightness difference between the cutting point to be cut and the surrounding gaps becomes larger, and the cutting point to be cut can be more clearly revealed, facilitating the cutting routing of the circuit board splitting machine and effectively improving the cutting efficiency and accuracy.

Detailed Embodiments

[0018] To more clearly illustrate the purpose, technical solutions, and advantages of the embodiments of the present utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments. The description is clear and complete. Obviously, the described embodiments are partial embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the protection scope of the present utility model. In addition, the directional terms mentioned in the present utility model, such as "upper", "lower", "front", "rear", "left", "right", "inner", "outer", etc., are only references to the directions in the attached drawings. The directional terms used are for better and clearer illustration and understanding of the present utility model, rather than indicating or implying the orientation that the present utility model must have. Therefore, it cannot be construed as a limitation to the present utility model.

[0019] Embodiments of the present utility model, such as Figures 1 to 4As shown in the figure, a circuit board separating fixture includes a base 1. The base 1 is used to mount the fixture on a corresponding working platform. The top surface of the base 1 is provided with a square base groove 10. The base 1 includes a square substrate and four side plates provided at the four edges of the top of the substrate. In this way, the space enclosed by the substrate and the four side plates forms the base groove 10. Light sources 2 are provided on the inner surfaces of the four groove walls of the base groove 10, that is, light sources 2 are provided on the inner surfaces of each side plate. The light sources 2 adopt LED lights, which have high brightness and are convenient for installation. At this time, side wall grooves 20 or side wall through holes for installing the light sources 2 are provided on the inner surfaces of the four groove walls of the base groove 10, that is, side wall grooves 20 or side wall through holes are provided on the inner surfaces of the four side plates. Then, the LED lights are installed in the side wall grooves 20 or side wall through holes, and then lamp covers are covered at the open ends of the side wall grooves 20 or at both ends of the side wall through holes. The lamp covers can be made of light guide plates. In order to irradiate all positions on the bottom surface of the PCB board 6 to be cut, that is, a large-area PCB board, more comprehensively when irradiating the PCB board 6 to be cut, multiple side wall grooves 20 or side wall through holes at different positions on the inner surface of each side plate can be provided. An LED light is installed in each side wall groove 20 or side wall through hole, and each LED light is electrically connected to a control switch 3 through a wire. The control switch 3 is used to control their lighting or turning off; an installation mechanism for installing the PCB board 6 to be cut and making a brightness difference at the position to be cut on the PCB board 6 to be cut by using the light emitted by the light source 2 is provided at the open end of the base groove 10. The installation mechanism is used to install the PCB board 6 to be cut, and it is provided at the open end of the base groove 10. After the PCB board 6 to be cut is installed on the installation mechanism, the bottom surface of the PCB board 6 to be cut faces the bottom of the base groove 10. The light emitted by the light sources 2 on the groove walls of the base groove 10 irradiates the bottom surface of the PCB board 6 to be cut. By irradiating with the light emitted by the light source 2, a brightness difference is formed at the position to be cut on the PCB board 6 to be cut, so as to more clearly show the position to be cut, which is convenient for the cutting route of the circuit board separating machine; a control switch 3 for controlling the light source 2 is provided on the base 1; during use, the circuit board 6 to be cut is installed on the installation mechanism, and then all the LED lights are turned on through the control switch 3. Since the LED lights are provided on the inner surfaces of the four side plates, all positions on the bottom surface of the circuit board 6 to be cut can be covered. When the light irradiates the gap between the small-area circuit boards on the circuit board 6 to be cut, the light will penetrate to enhance the brightness at this place. When the light irradiates the cutting point between the small-area circuit boards, the cutting point will block the emission of light. In this way, the brightness difference between the cutting point and the surrounding gaps becomes larger, and the cutting point can be more clearly revealed, which is convenient for the cutting route of the circuit board separating machine and can effectively improve the cutting efficiency and accuracy.

[0020] Further improvement, such asFigure 1 and Figure 4 As shown in Figure 4 , the bottom of the base groove 10 is provided with bottom through holes 11 in a grid pattern. The bottom through holes 11 can be used to ventilate and dissipate heat in the base groove 10. A baffle 12 covering the bottom through holes 11 is erected on the bottom of the base groove 10. A plurality of support columns are arranged at equal intervals around the bottom through holes 11 on the bottom of the base groove 10. For example, two or three support columns are provided. The baffle 12 is arranged on the tops of the plurality of support columns. For example, the two are connected by screws or welded together. At this time, the baffle 12 is erected above the bottom through holes 11 to prevent debris from falling into the bottom through holes 11 during the cutting process and causing blockage.

[0021] For further improvement, for the installation mechanism, as Figure 1 shown in Figure 1 , in one case, the installation mechanism is a step 4 that is recessed at the open end of the base groove 10 and surrounds the inner wall of the base groove 10 for one week. The step 4 makes the base groove 10 form a countersunk head structure at the open end. During use, the PCB board 6 to be cut is placed into the base groove 10 from the open end. Then, the bottom surface of the PCB board 6 to be cut abuts against the step 4. The PCB board 6 to be cut is installed in the base groove 10 in an overhead manner. At this time, in the base groove 10, there is no obstruction on the bottom surface of the PCB board 6 to be cut. The light emitted by the light source 2 can irradiate on the bottom surface of the PCB board 6 to be cut. The gaps in the structure of the PCB board 6 to be cut transmit light, increasing the brightness. The point to be cut blocks the light, and the brightness difference between the point to be cut and its surrounding area becomes larger, so that the point to be cut can be more clearly displayed. As Figures 2 - 4 shown in Figures 2 - 4 , in another case, the installation mechanism includes a cover plate 5 covering the open end of the base groove 10, a countersunk cover plate through hole 50 provided in the middle of the cover plate 5, or a cover plate groove with a light-transmitting through hole provided at the countersunk bottom. The PCB board 6 to be cut is installed at the countersunk position of the cover plate through hole 50 or the cover plate groove. The cover plate 5 is detachably covered on the base groove 10 to close the base groove 10. For example, the two are connected by screws. In this way, cover plate through holes 50 or cover plate grooves of different sizes can be correspondingly provided on a plurality of cover plates 5 according to the size of the PCB board 6 to be cut. One cover plate 5 corresponds to one PCB board 6 to be cut. The cover plate 5 can be replaced on the base groove 10 according to different usage requirements, so as to realize the cutting of different PCB boards and meet more usage requirements.

[0022] For further improvement, as Figure 1 and Figure 4As shown in the figure, a plurality of light sources 2 are provided on the groove walls of each base groove 10. The plurality of light sources 2 enable the space in front of the groove walls of the corresponding base grooves 10 to be evenly illuminated. For example, if four light sources 2 are provided on the groove wall of each base groove 10, the four light sources 2 are correspondingly arranged at the upper left, lower left, upper right, and lower right positions of the groove wall, and the corresponding settings are made according to different numbers of light sources.

[0023] A circuit board splitting machine uses the splitting fixture described in any of the foregoing items. The splitting fixture described above is provided on the circuit board splitting machine. When cutting, all the light sources are lit, and a brightness difference will be generated at the cutting points of the large-area PCB board, so that the cutting points can be more clearly displayed, thus avoiding the problems of unclear cutting points and incorrect cutting by the circuit board splitting machine.

[0024] Although the present invention has been described in detail above with general descriptions and specific embodiments, on the basis of the present invention, some modifications or improvements can be made, which are obvious to those skilled in the art. Therefore, these modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
