Description

Technical Field

[0001] This utility model relates to the field of circuit boards, and more specifically, to a circuit board carrier for mounting. Background Technology

[0002] In the production process of printed circuit boards (PCBs), surface mount technology (SMT) is required on the PCB surface. Precise positioning and stable fixation of the PCB are crucial to ensuring SMT quality. Traditional positioning fixtures use simple positioning slots to position the PCB. However, during the movement of the fixture, vibration or collision can easily cause the PCB to fall off and become misaligned, affecting the accuracy of SMT and even leading to the scrapping of the PCB. Utility Model Content

[0003] The purpose of this utility model is to provide a circuit board carrier for mounting, which has a reasonable structure and can ensure the stability and reliability of the circuit board during the mounting process, thereby improving the mounting quality.

[0004] A circuit board mounting carrier includes: a carrier plate having a downwardly recessed positioning groove in its middle; and a clamping assembly symmetrically disposed on two opposite sides of the positioning groove extending along a first direction; the clamping assembly includes clamping blocks and a plurality of elastic elements, the plurality of elastic elements being arranged along the first direction and compressed between the clamping blocks and the carrier plate; two of the clamping blocks are slidable relative to the carrier plate along a second direction perpendicular to the first direction to clamp and fix the circuit board placed in the positioning groove by the restoring force of the elastic elements.

[0005] In the aforementioned technical solution, a positioning groove is provided on the carrier plate, and a pair of clamping assemblies are symmetrically arranged on a set of opposite sides of the positioning groove. The restoring force generated by the elastic element of the clamping assembly under compression allows the clamping block to clamp the circuit board placed in the positioning groove. On the one hand, this can improve the stability of the circuit board on the carrier and improve the mounting quality. On the other hand, it allows the clamping block to adapt to the size of the circuit board and compensate for the dimensional tolerance of the circuit board. Even when the equipment vibrates, it can still maintain close contact between the clamping surface and the edge of the circuit board, further improving the reliability of positioning.

[0006] Furthermore, the support plate is provided with a base plate below the positioning groove, and the clamping block includes a main body connected to the elastic member and a clamping part extending from the main body to the upper surface of the base plate.

[0007] In the above technical solution, the circuit board is clamped by the clamping part extending to the upper surface of the base plate, which can ensure that the clamping part is flush with the circuit board placed in the positioning groove, thus ensuring the accuracy of clamping. At the same time, it can avoid interference between the clamping part and the carrier plate when sliding, thus ensuring that the clamping part slides smoothly and steadily.

[0008] Furthermore, the main body is provided with a mounting groove for accommodating the elastic element on the side facing the elastic element.

[0009] In the aforementioned technical solution, the mounting groove provided in the main body can easily accommodate the elastic element and limit its circumferential movement, thereby preventing the elastic element from coming off under the action of elastic force.

[0010] Furthermore, the base plate has at least one window area that extends through the base plate.

[0011] In the above technical solution, the through-hole design of the window area can ensure that there is no gap for protruding structures or existing components on the circuit board, and ensure that the circuit board is placed stably.

[0012] Furthermore, a guide rod is provided between the clamping block and the bearing plate. One end of the guide rod is fixedly connected to one of the clamping block and the bearing plate, and the other end of the guide rod is slidably connected to the other of the clamping block and the bearing plate.

[0013] In the described technical solution, the guide rod can connect the clamping block and the bearing plate, while restricting the clamping block to move linearly only in the second direction, thus preventing the clamping block from deflecting during movement and ensuring effective and stable clamping.

[0014] Furthermore, the elastic element is sleeved on the outer periphery of the guide rod.

[0015] In the above technical solution, the elastic element is sleeved on the outer periphery of the guide rod, which can ensure the stability of the elastic element structure.

[0016] Furthermore, the extending direction of the clamping block is parallel to the first direction.

[0017] In the above technical solution, the extension direction of the clamping block is parallel to the first one, so that the clamping force distribution of the working surface of the clamping block corresponds to the long side of the circuit board, thereby increasing the effective clamping area and making the circuit board more uniformly stressed.

[0018] Furthermore, each of the clamping blocks has at least one arc-shaped groove at one end facing the other clamping block.

[0019] In the described technical solution, when the clamping block clamps the circuit board, the arc-shaped groove can form a gap between the clamping block and the circuit board, making it convenient to push the clamping block and remove the circuit board.

[0020] Furthermore, the corner of the positioning groove is provided with an arc-shaped clearance groove.

[0021] In the above technical solution, the clearance slot facilitates the placement and removal of circuit board components, making the operation more convenient.

[0022] Compared with the prior art, the beneficial effects of this utility model are as follows: the bearing plate is provided with a positioning groove, and a pair of clamping components are symmetrically arranged on a set of opposite sides of the positioning groove. Through the restoring force generated by the elastic element of the clamping component under compression, the clamping block clamps the circuit board placed in the positioning groove. On the one hand, it can improve the stability of the circuit board on the carrier and improve the mounting quality. On the other hand, it can enable the clamping block to adapt to the size of the circuit board and compensate for the dimensional tolerance of the circuit board. Even when the equipment vibrates, it can still maintain close contact between the clamping surface and the edge of the circuit board, further improving the reliability of positioning.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0030] Please refer to Figures 1 to 3In a preferred embodiment, the mounting circuit board carrier of this utility model mainly includes a carrier plate 1 and a clamping assembly 2. The carrier plate 1 has a downwardly recessed positioning groove 11 in its center. The clamping assembly 2 is symmetrically arranged on two opposite sides of the positioning groove 11 extending along a first direction. The clamping assembly 2 includes clamping blocks 21 and multiple elastic elements 22. The multiple elastic elements 22 are arranged along the first direction and compressed between the clamping blocks 21 and the carrier plate 1. Two clamping blocks 21 can slide relative to the carrier plate 1 along a second direction perpendicular to the first direction, so as to clamp and fix the circuit board placed in the positioning groove 11 by the restoring force of the elastic elements 22.

[0031] For example, the carrier plate 1 is generally rectangular and is made of existing metal or alloy materials, such as aluminum alloy. A positioning groove 11 is formed by a downward indentation near the center of the carrier plate 1. In this embodiment, the positioning groove 11 is generally rectangular, with the first direction being the length direction of the positioning groove 11 and the second direction being the width direction of the positioning groove 11. Clamping blocks 21 are symmetrically arranged on a set of opposite sides of the positioning groove 11. Through the restoring force generated by the elastic element 22 of the clamping assembly 2 under compression, the clamping blocks 21 clamp the circuit board placed in the positioning groove 11. This improves the stability of the circuit board on the carrier, enhancing the mounting quality. Furthermore, the clamping blocks 21 can adapt to the size of the circuit board, compensating for dimensional tolerances, and maintaining close contact between the clamping surface and the edge of the circuit board even during equipment vibration, further improving positioning reliability.

[0032] In this embodiment, a base plate 14 is provided below the positioning groove 11 corresponding to the support plate 1. The clamping block 21 includes a main body 211 connected to the elastic member 22 and a clamping part 212 extending from the main body 211 to the upper surface of the base plate 14. By clamping the circuit board with the clamping part 212 extending to the upper surface of the base plate 14, it is possible to ensure that the clamping part 212 is flush with the circuit board placed in the positioning groove 11, ensuring the accuracy of clamping. At the same time, it can avoid interference between the clamping part 212 and the support plate 1 when sliding, ensuring that the clamping part 212 slides smoothly and steadily.

[0033] The main body 211 has a mounting groove 213 for accommodating the elastic member 22 on the side facing the elastic member 22. The mounting groove 213 provided in the main body 211 can easily accommodate the elastic member 22 and limit the elastic member 22 in the circumferential direction to prevent the elastic member 22 from falling out under the action of elastic force.

[0034] The base plate 14 has at least one window area 13 that extends through the base plate 14. For example, the window area 13 may correspond to a protruding structure or existing component on the circuit board. The window area 13 extends through the base plate 14 in the height direction, which can ensure that there is a gap for the protruding structure or existing component on the lower surface of the circuit board, and ensure that the circuit board is placed stably.

[0035] A guide rod 23 is provided between the clamping block 21 and the support plate 1. One end of the guide rod 23 is fixedly connected to one of the clamping block 21 and the support plate 1, and the other end of the guide rod 23 is slidably connected to the other of the clamping block 21 and the support plate 1. The guide rod 23 can connect the clamping block 21 and the support plate 1, while restricting the clamping block 21 to move linearly only in the second direction, preventing the clamping block 21 from deflecting during movement, and ensuring effective and stable clamping.

[0036] The elastic element 22 is sleeved on the outer periphery of the guide rod 23. In a specific implementation, the elastic element 22 can be a spring, which is sleeved on the outer periphery of the guide rod 23 to ensure the stability of the elastic element 22 structure.

[0037] In this embodiment, the extension direction of the clamping block 21 is parallel to the first direction, so that the clamping force distribution of the working surface of the clamping block 21 corresponds to the long side of the circuit board, thereby increasing the effective clamping area and making the circuit board more uniformly stressed.

[0038] Each clamping block 21 has at least one arc-shaped groove 214 at one end facing another clamping block 21. When the clamping block 21 clamps the circuit board, the arc-shaped groove 214 can form a gap between the clamping block 21 and the circuit board, making it convenient to push the clamping block 21 and remove the circuit board.

[0039] The corner of the positioning groove 11 is provided with an arc-shaped clearance groove 12, which facilitates the placement and removal of the circuit board assembly, making the operation more convenient.
