Description

Technical Field

[0001] This utility model relates to the field of PCBA testing technology, specifically a fixture mechanism for PCBA functional testing equipment. Background Technology

[0002] PCBA functional test equipment fixture mechanism is a device used to fix and connect PCBA (Printed Circuit Board Assembly) for functional testing.

[0003] In the prior art, when clamping the PCBA body, a hydraulic structure combined with a rigid clamping plate is usually used for clamping and fastening. However, the above structure does not have a deformation effect, and there are certain tolerances or irregular shapes around the PCBA body. As a result, the above structure is difficult to fit tightly to the PCBA body, which easily leads to displacement during subsequent testing. Therefore, a new structure is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixture mechanism for PCBA functional testing equipment to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model relates to a fixture mechanism for PCBA functional testing equipment, comprising:

[0006] The PCBA body consists of two receiving bases, with the PCBA body movably placed between the top of the receiving bases.

[0007] A protective clamping assembly includes a C-shaped frame, a guide groove, a guide rod, a pressure plate, a silicone plate, and a spring. The top of one end of the receiving seat is fixedly connected to the C-shaped frame. A guide groove is formed through the C-shaped frame. A guide rod is movably connected in the guide groove. A pressure plate is fixedly connected to the bottom of the guide rod. A silicone plate is fixedly connected to the bottom of the pressure plate. A spring is movably sleeved on the outside of the guide rod.

[0008] Furthermore, the PCBA body is located between the bottom of the silicone plate and the top of the support.

[0009] Furthermore, the protective clamping assembly also includes a limiting block, which is fixedly connected to the top of the guide rod.

[0010] Furthermore, the protective clamping assembly also includes a locking groove and a U-shaped locking rod. The locking groove is opened through the C-shaped frame and the pressure plate, and the U-shaped locking rod is movably inserted between the locking grooves.

[0011] Furthermore, the protective clamping assembly also includes a protective groove, which is formed on the receiving seat.

[0012] Furthermore, it also includes an auxiliary adaptation adjustment component, which includes a rectangular groove and a cross-shaped receiving rod. The receiving seat has rectangular grooves extending through both ends, and the cross-shaped receiving rod is movably inserted between the rectangular grooves.

[0013] Furthermore, the auxiliary adaptation adjustment component also includes threaded grooves, with threaded grooves formed at both ends of the receiving seat, and the threaded grooves communicating with the rectangular groove.

[0014] Furthermore, the auxiliary adaptation adjustment assembly also includes an adjustment screw, which is movably connected in the threaded groove.

[0015] This utility model has the following beneficial effects:

[0016] This invention, due to the elastic deformation capability of the spring and the soft texture and elasticity of the silicone plate, provides excellent adaptability when combined. Even if the PCBA body has certain tolerances or irregular shapes, it can achieve tight clamping through compression and stretching, thereby preventing displacement of the PCBA body during the testing process.

[0017] Based on the aforementioned beneficial effects, by moving the two end receiving seats along the cross-shaped receiving rod and then tightening the adjusting screw at the threaded groove, the distance between the two end receiving seats can be adjusted and fixed, thereby enabling the clamping of PCBA bodies of different lengths. This improves the adaptability of the device, while avoiding over-clamping and unnecessary pressure, protecting the electronic components and circuit boards on the PCBA body, and reducing the scrap rate of the product (for example, if a fixed-length clamp is used to clamp a shorter PCBA body, the clamping force may be concentrated at both ends, causing damage to the PCBA body).

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 As shown, this utility model is a fixture mechanism for PCBA functional testing equipment, comprising:

[0029] The PCBA body 102 consists of two support brackets 101, with the PCBA body 102 movably placed on top of each other between the support brackets 101.

[0030] The protective clamping assembly includes a C-shaped frame 201, a guide groove 202, a guide rod 203, a pressure plate 204, a silicone plate 205, and a spring 206. The top of one end of the receiving seat 101 is fixedly connected to the C-shaped frame 201. The guide groove 202 is formed through the C-shaped frame 201. The guide rod 203 is movably connected to the guide groove 202. The bottom of the guide rod 203 is fixedly connected to the pressure plate 204. The bottom of the pressure plate 204 is fixedly connected to the silicone plate 205. The spring 206 is movably sleeved on the outside of the guide rod 203. The PCBA body 102 is located between the bottom of the silicone plate 205 and the top of the receiving seat 101.

[0031] The PCBA body 102 is movably placed on the top of the receiving seat 101. The C-shaped frame 201 ensures the opening of the guide groove 202. The guide groove 202 ensures the movable connection of the guide rod 203. The pressure plate 204 ensures the silicone plate 205 presses and clamps the PCBA body 102. The spring 206 ensures the generation of a firm clamping force.

[0032] The protective clamping assembly also includes a limiting pull block 207, and the limiting pull block 207 is fixedly connected to the top of the guide rod 203;

[0033] The limit block 207 is designed to make it easy for the user to pull the pressure plate 204 up and down.

[0034] The protective clamping assembly also includes a locking groove 208 and a U-shaped locking rod 209. The locking groove 208 is opened through the C-shaped frame 201 and the pressure plate 204, and the U-shaped locking rod 209 is movably inserted between the locking grooves 208.

[0035] The locking groove 208 and the U-shaped locking rod 209 work together to limit the pressure plate 204, while creating a gap between the silicone plate 205 and the receiving seat 101, which facilitates the upright placement of the PCBA body 102 before clamping.

[0036] The protective clamping assembly also includes a protective groove 2010, which is provided on the receiving seat 101;

[0037] The protective groove 2010 can place the protruding parts such as pins and electronic components on the PCBA body 102, avoiding squeezing the pins and electronic components and effectively preventing damage to the pins and electronic components.

[0038] Working principle: First, pull the limiting block 207 upward. At this time, with the cooperation of the guide rod 203, the pressure plate 204 and silicone plate 205 are driven to move upward. At this time, the spring 206 is compressed and deformed. Then, insert the two ends of the U-shaped locking rod 209 into the two locking grooves 208. Then, the end of the PCBA body 102 with the protruding structure is fastened to the protective groove 2010. At the same time, the flat parts on both sides of the PCBA body 102 are placed on the top of the receiving seat 101 and the bottom of the silicone plate 205. Then, the U-shaped locking rod 209 is taken out from the locking groove 208. At this time, the spring 206 loses its force and pushes the pressure plate 204 and silicone plate 205 downward to press and clamp the two sides of the PCBA body 102. This step can achieve a tight fit and clamping of the PCBA body 102.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The rectangular groove 301 and the cross-shaped receiving rod 302 work together to ensure the movement of the receiving seat 101.

[0042] The auxiliary adaptation adjustment component also includes a threaded groove 303, with threaded grooves 303 at both ends of the receiving seat 101, and the threaded grooves 303 connecting to the rectangular groove 301; the auxiliary adaptation adjustment component also includes an adjusting screw 304, which is movably connected in the threaded groove 303.

[0043] The threaded groove 303 and the adjusting screw 304 are used together to fix the bearing seats 101 at both ends after they have moved.

[0044] Working principle: Before starting the above embodiment, the distance between the two end support seats 101 is adjusted. First, the length of the PCBA body 102 under test is measured. Then, the two end support seats 101 are moved along the cross-shaped support rod 302. When the distance between the two end support seats 101 is equal to the length of the PCBA body 102 under test, the adjusting screw 304 is turned at the threaded groove 303. At this time, one end of the adjusting screw 304 is clamped to the cross-shaped support rod 302, thereby fixing the two end support seats 101 after movement.
