Abstract
Description
Technical Field
[0001] The utility model belongs to the field of LED kits, relates to the design of a circuit board, and particularly relates to a V-CUT connection structure of a circuit board of an LED kit. Background Art
[0002] The circuit board is the core component in the LED kit. During the production process of the circuit board, multiple circuit boards are connected into a whole through V-CUT, so the circuit boards need to be separated along the V-CUT. This process is called depaneling. During the depaneling process, if the V-CUT is too shallow, it will make depaneling difficult. If the V-CUT is deepened, it will be easier to depanel. However, due to the depaneling resistance generated during the depaneling process, the circuit board V-CUT is prone to breakage and the components on the circuit board close to the V-CUT are easily damaged, resulting in poor depaneling effect and reduced yield rate. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, a V-CUT connection structure for the circuit board of an LED kit is provided. Through the design of the first gong groove and the second gong groove, not only can the difficulty of separating the board be reduced and the occurrence of board breakage be prevented, but also the lateral force transmission during separation can be avoided to damage components and plug-ins, thereby ensuring a good board separation effect and improving the yield rate.
[0004] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides a circuit board V-CUT connection structure of an LED kit, including several circuit boards, adjacent circuit boards are connected by V-CUT to form a V-CUT edge, and several evenly distributed first gong grooves are provided on the V-CUT edge, and second gong grooves are provided on the V-CUT edge near the components and plug-ins on the circuit board.
[0005] Furthermore, the first gong groove and the second gong groove are both symmetrically arranged between adjacent circuit boards according to the V-CUT edge.
[0006] Furthermore, the first gong grooves are arranged at equal intervals on the edge of the V-CUT.
[0007] Furthermore, the width of the first gong groove and the second gong groove are both 1.2-2.0 mm.
[0008] Furthermore, process edges are provided on the sides of the circuit board at both ends, and the process edges are connected to the circuit board through V-CUT to form V-CUT edges. Several evenly distributed first gong grooves are provided on the V-CUT edges, and second gong grooves are provided on the V-CUT edges near the components on the circuit board.
[0009] Beneficial effect: Compared with the existing technology, the utility model realizes segmented processing of the V-CUT edge through the design of the first gong groove and the second gong groove, effectively reducing the contact area and contact length of adjacent circuit boards, which can not only reduce the resistance of board separation, thereby reducing the difficulty of board separation, improve the efficiency of board separation and prevent the occurrence of board breakage, but also the design of the second gong groove can avoid the lateral force transmission during board separation from damaging components, ensuring a good board separation effect and improving the yield rate. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 This is a structural diagram of the utility model. DETAILED DESCRIPTION
[0011] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.
[0012] like Figure 1 As shown, the utility model provides a circuit board V-CUT connection structure of an LED kit, including four circuit boards 1 and two process edges 2. Adjacent circuit boards 1 are connected by V-CUT to form V-CUT edges 3. The two process edges 2 are respectively connected to the sides of the two end circuit boards 1 by V-CUT. V-CUT edges 3 are also formed between the process edges 2 and the circuit board 1, so that a total of 5 V-CUT edges 3 are generated. Each V-CUT edge 3 is provided with 5 evenly distributed first grooves 4 and 1 second groove 5. The second groove 5 is located near the component 6 on the circuit board. The first groove 4 and the second groove 5 are symmetrically arranged between adjacent circuit boards 1 and between the circuit board 1 and the process edge 2 according to the V-CUT edge 3. The groove width of the first groove 4 and the second groove 5 is 1.2 mm, and the width of the process edge 2 is 4 mm.
[0013] In this embodiment, the above-mentioned circuit board V-CUT connection structure is separated into panels. Specifically, the staff separates the circuit board 1 along the V-CUT edge 3. During the separation process, the first gong groove 4 and the second gong groove 5 segment the V-CUT edge 3, which reduces the resistance during separation, ensures that rapid separation can be achieved, improves the separation efficiency, and due to the segmented force, it can prevent the occurrence of broken panels. In addition, during the separation process, the setting of the second gong groove 5 can avoid the lateral force transmission during separation from damaging the components 6, thereby ensuring a good separation effect and improving the yield rate.
