Description

Technical Field

[0001] This utility model relates to the field of stamping equipment technology, and in particular to a positioning device for stamping electronic components. Background Technology

[0002] PCB (Printed Circuit Board), also known as a printed circuit board, is an important electronic component. It serves as the support for electronic components and the carrier for their electrical interconnection. Because it is manufactured using electronic printing technology, it is called a "printed" circuit board. Stamping is an extremely important processing step in the production of printed circuit boards.

[0003] The Chinese utility model patent (authorization announcement number: CN205160943U, title: A stamping machine for processing rigid-flexible joint plates) includes an upper support, support columns, a base, a work platform, an electric cylinder, a lifting platform, and a stamping head. The upper support is fixedly connected to the base via the support columns. The work platform is fixedly installed on the base. The lifting platform is connected to the bottom of the upper support via the electric cylinder. The stamping head is installed at the bottom of the lifting platform. The work platform is square and has four positioning columns. The four positioning columns are movably connected to the work platform via a position adjustment device. A stamping die is fixedly connected to the work platform between the four positioning columns. This design can handle the stamping of rigid-flexible joint plates of different specifications by adjusting the position of the four positioning columns, thus improving its practicality. However, the fixed position of the positioning columns makes it easy to encounter situations where precise positioning is not possible due to different specifications of the processed circuit boards. This limits the overall usability and performance, making it difficult to meet the diverse needs of different usage scenarios, significantly restricting the overall functionality and narrowing the overall applicability.

[0021] like Figure 1 As shown, a positioning device for stamping electronic components includes a base 1 and a cover plate 2. A negative pressure chamber is formed on the base 1. The cover plate 2 is detachably installed on the opening of the negative pressure chamber. A through hole is formed on the inner wall of the negative pressure chamber. An air pipe connector 3 is installed at the end of the through hole away from the negative pressure chamber. Several air holes 4 are arranged in a matrix on the bottom of the negative pressure chamber. Four positioning blocks 5 are provided on the base 1, located at the four outer corners of the matrix. The positioning blocks 5 are L-shaped, with their inner corners facing the center of the base 1. T-slots 6 corresponding to the positioning blocks 5 are formed on the base 1, extending to the outer side of the base 1. A nut 7 is slidably installed in the T-slot 6. An elongated oval through hole 8 is provided on one side of the L-shape of the positioning block 5. The elongated oval through hole 8 intersects with the T-slot 6 to form a cross shape. A bolt 9 passes through the elongated oval through hole 8 and is screwed into the nut 7 (preferably, there are two parallel elongated oval through holes 8, which can prevent rotation during adjustment). Through the cooperation of the T-slot 6 and the elongated oval through hole 8, the size of the area enclosed by the positioning block 5 can be adjusted to fit circuit boards of different specifications. This not only meets the various usage requirements under different new usage conditions, but also achieves precise positioning and ensures the smoothness of the overall operation.

[0022] In this embodiment, as Figure 1 As shown, a sealing groove 10 is also provided on the base 1. The sealing groove 10 surrounds the outside of the matrix. Four positioning blocks 5 surround the outside of the sealing groove 10. A sealing ring 11 is installed in the sealing groove 10, which improves the adsorption force of the air hole 4 on the circuit board to be stamped and reduces the risk of the circuit board jumping during the stamping process. The sealing ring 11 includes a rubber body ring 12. An A protrusion ring 13 is integrally formed on the inner or outer ring of the body ring 12. The A protrusion ring 13 is concentric with the body ring 12 and extends to the bottom of the body ring 12. The connection between the A protrusion ring 13 and the side wall of the body ring 12 is smoothly transitioned. The sealing groove 10 and the sealing ring 11 are adapted to each other. The A protrusion ring 13 is inserted into the sealing groove 10, which not only increases the filling rate of the sealing ring 11 in the sealing groove 10 and improves the sealing effect, but also makes the structure of the sealing ring 11 more stable and less likely to fall off after installation.

[0023] In this embodiment, as Figure 1 As shown, a shrinkage groove 14 is provided at the bottom of the body ring 12. The shrinkage groove 14 is circular and concentric with the body ring 12. When the sealing ring 11 is inserted into the sealing groove 10, the shrinkage groove 14 deforms and shrinks, making it easier to insert the sealing ring 11. After being inserted, the sealing ring 11 recovers under the action of elastic force and is thus stuck in the sealing groove 10. The structure is stable and not easy to fall off.

[0024] In this embodiment, as Figure 1 As shown, a B-shaped protrusion 15 is integrally formed on the top of the body ring 12. The B-shaped protrusion 15 is concentric with the body ring 12, and the connection between the B-shaped protrusion 15 and the side wall of the body ring 12 is smooth. A gap is provided between the side wall of the body ring 12 and the inner wall of the sealing groove 10. The top of the B-shaped protrusion 15 is located above the opening of the sealing groove 10. When the sealing ring 11 is not working, the sealing ring 11 is secured in the sealing groove 10 by the A-shaped protrusion 13 to prevent it from falling out of the sealing groove 10, thus avoiding the sealing ring 11 from being stuck in the sealing groove 10 due to deformation. When the sealing ring 11 is working, the B protruding ring 15 is pressed into the sealing groove 10, and the entire sealing ring 11 deforms, thereby filling the gap between the sealing ring 11 and the sealing groove 10. This prevents leakage and avoids secondary deformation of the sealing ring 11 (the O-ring sealing ring 11 relies on primary deformation to be stuck in the sealing groove 10, but during operation, it needs to seal the gap between two workpieces, so the part protruding above the sealing groove 10 will be compressed into the sealing groove 10, i.e., secondary deformation), which could cause damage due to excessive stress in the sealing ring 11.

[0025] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
