Description

Technical Field

[0001] This utility model relates to the field of PCB board application technology, and in particular to a PCB board testing fixture. Background Technology

[0002] PCB is short for Printed Circuit Board. It is a type of circuit board formed by coating a conductive material onto a non-conductive material. Its main function is to electrically connect electronic components together. Therefore, circuit testing on PCBs is particularly important.

[0003] Traditional PCB testing is typically performed manually, which is inefficient. Furthermore, manual operation requires constant monitoring of the test results, increasing workload and further reducing testing efficiency. Therefore, this invention proposes a PCB testing fixture. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a PCB board testing fixture to solve the inconvenience caused by the traditional manual installation and testing mode, thereby improving the efficiency of PCB board testing.

[0005] To solve the above-mentioned technical problems, the present invention provides a PCB board testing fixture, including a base plate, a telescopic mechanism fixedly connected to the top of the base plate, a side-pushing mechanism bolted to the top of the telescopic mechanism, a positioning frame bolted to the top of the side-pushing mechanism, a PCB board body installed inside the positioning frame, a support frame fixedly connected to the middle of the base plate, and a clamping mechanism detachably installed on the top of the support frame.

[0006] The present invention is further configured such that: the telescopic mechanism includes a telescopic cylinder bolted to the base plate, a movable plate bolted to the end face of the drive rod of the telescopic cylinder, and slide rails symmetrically bolted to the bottom of the movable plate near the side wall, and the two slide rails are respectively slidably connected to two guide seats installed on the top of the base plate.

[0007] The above technical solution activates the telescopic cylinder, whose drive rod moves the movable plate connected to the end face, and uses the slide rail to slide stably inside the guide seat, thereby improving the stability of the PCB board body when it extends and retracts.

[0008] The present invention is further configured such that: the side-push mechanism includes a side-push cylinder mounted on the telescopic mechanism, the drive rod end face of the side-push cylinder is bolted to a push plate, and the bottom of the push plate is slidably connected to a stabilizing seat mounted on a movable plate near the side wall.

[0009] The above technical solution activates the side-push cylinder, whose drive rod moves the push plate on the end face, thereby enabling the push plate to drive the PCB board body on top to perform electrical connection tests with the relevant test equipment interface.

[0010] The present invention is further configured such that: the side wall of the positioning frame is symmetrically fixedly connected with bolt locking components, and the PCB board body is locked and fixed by the bolt locking components.

[0011] The above technical solution facilitates the locking and fixing of the PCB board body installed inside the positioning frame, ensuring its secure installation.

[0012] The present invention is further configured such that: the clamping mechanism includes a mounting plate slidably connected to the support frame; a clamping cylinder is bolted to the middle position of the mounting plate; a connecting plate is bolted to the end face of the drive rod of the clamping cylinder; a pressure plate is bolted to the bottom of the connecting plate; stabilizing rods are symmetrically fixedly connected to the top of the pressure plate near the side wall; a cooperating cylinder is bolted to the inner top of the support frame, and the end face of the drive rod of the cooperating cylinder is connected to the top of the mounting plate.

[0013] Through the above technical solution, the clamping cylinder is activated, and its drive rod drives the connecting plate on the end face to move, thereby pressing and fixing the PCB board body with the bottom pressure plate. In addition, the activation of the cooperating cylinder can cooperate with the side pushing mechanism to ensure that the clamping mechanism is always pressed on the PCB board body, preventing displacement during side pushing.

[0014] The present invention is further configured such that: the bottom of the mounting plate is symmetrically bolted with sliding blocks near the side wall, and the interior of each of the two sliding blocks is slidably connected with a guide rail mounted on the support frame.

[0015] The above technical solution facilitates stable sliding of the mounting plate on the guide rail via the slide block when the mounting plate is pushed, thereby improving the stability of the PCB board body.

[0016] The present invention is further configured such that: multiple exhaust fans are uniformly fixedly connected to the bottom of the pressure plate; positioning posts are symmetrically fixedly connected to the bottom of the pressure plate near the side wall; and two positioning posts are respectively inserted into the positioning sleeves symmetrically arranged at the top of the positioning frame near the side wall; multiple elastic protective parts are uniformly fixedly connected to the bottom of the pressure plate; and electrical connectors are symmetrically fixedly connected to the bottom of the pressure plate near the center.

[0017] Through the above technical solutions, multiple exhaust fans can be used to dissipate high temperatures on the PCB board body during testing, and positioning devices can be used to accurately fix the position during clamping to prevent clamping deviation. Elastic protective components can be used to protect the surface of the PCB board body during clamping to prevent damage. At the same time, electrical connectors can be used to cooperate with external testing equipment for testing.

[0018] The present invention is further configured such that the drive rod of the clamping cylinder and the two stabilizing rods both pass through the support frame through the movable slots opened inside the support frame, and are movably arranged inside the movable slots.

[0019] The above technical solution facilitates the pressing mechanism to perform limiting movements inside the movable slot when the side pushing mechanism is pushing, thereby enabling the PCB board body to be connected to the testing equipment to complete the testing operation.

[0030] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0031] like Figures 1-4 As shown, a PCB board testing fixture includes a base plate 1. A telescopic mechanism 2 is fixedly connected to the top of the base plate 1. The telescopic mechanism 2 includes a telescopic cylinder 21 bolted to the base plate 1. A movable plate 22 is bolted to the end face of the drive rod of the telescopic cylinder 21. Slide rails 221 are symmetrically bolted to the bottom of the movable plate 22 near the side wall. The two slide rails 221 are slidably connected to two guide seats 222 installed on the top of the base plate 1. When the telescopic cylinder 21 is activated, its drive rod drives the movable plate 22 connected to the end face to move, and the slide rails 221 slide stably inside the guide seats 222, thereby improving the stability of the PCB board body 5 when extending and retracting. A side-pushing mechanism 3 is bolted to the top of the telescopic mechanism 2. The side-pushing mechanism 3 includes a side-pushing mechanism 3 installed on the bottom of the base plate 1. The side-push cylinder 31 on the telescopic mechanism 2 has a push plate 32 bolted to the end face of the drive rod of the side-push cylinder 31. The bottom of the push plate 32 is slidably connected to the stabilizing seat 33 installed on the moving plate 22 near the side wall. When the side-push cylinder 31 is activated, its drive rod drives the push plate 32 at the end face to move, so that the push plate 32 can drive the PCB board body 5 at the top to perform electrical connection test with the relevant test equipment interface. The top of the side-push mechanism 3 is bolted to the positioning frame 4. The side wall of the positioning frame 4 is symmetrically fixed with bolt locking parts 42, and the PCB board body 5 is locked and fixed by the bolt locking parts 42, which facilitates the locking and fixing of the PCB board body 5 installed inside the positioning frame 4, so that it is firmly installed. The PCB board body 5 is installed inside the positioning frame 4.

[0032] like Figures 4-6As shown, a support frame 6 is fixedly connected to the middle of the base plate 1. The drive rod of the clamping cylinder 72 and the two stabilizing rods 75 pass through the support frame 6 through the movable slot 61 opened inside the support frame 6, and are movably set inside the movable slot 61. This allows the clamping mechanism 7 to cooperate with the side pushing mechanism 3 to perform limited movement inside the movable slot 61 when pushing, thereby connecting the PCB board body 5 to the testing equipment to complete the testing operation. The clamping mechanism 7 is detachably installed on the top of the support frame 6. The clamping mechanism 7 includes a mounting plate 71 that is slidably connected to the support frame 6. The bottom of the mounting plate 71 is symmetrical near the side wall. The mounting plate 71 is bolted to a slide block 711. Both slide blocks 711 have guide rails 712 slidably connected to the inside, mounted on the support frame 6. This allows the mounting plate 71 to slide stably on the guide rails 712 when pushed, improving the stability of the PCB board body 5. A clamping cylinder 72 is bolted to the middle of the mounting plate 71. A connecting plate 73 is bolted to the end face of the drive rod of the clamping cylinder 72. A pressure plate 74 is bolted to the bottom of the connecting plate 73. Multiple exhaust fans 741 are evenly fixedly connected to the bottom of the pressure plate 74. A set of fixed fans is symmetrically fixedly connected to the bottom of the pressure plate 74 near the side wall. Positioning posts 742 are inserted into the positioning sleeves 41 symmetrically arranged near the side wall of the top of the positioning frame 4. Multiple elastic protective elements 743 are evenly fixedly connected to the bottom of the pressure plate 74. Electrical connectors 744 are symmetrically fixedly connected to the bottom of the pressure plate 74 near the center. Multiple exhaust fans 741 can provide high-temperature heat dissipation for the PCB board body 5 during testing. The positioning posts 742 can accurately fix the position during clamping, preventing clamping deviation. The elastic protective elements 743 can protect the surface of the PCB board body 5 during clamping, preventing damage. Damage can be detected, and the electrical connector 744 can be used to test with external testing equipment. The top of the pressure plate 74 is symmetrically fixed with a stabilizing rod 75 near the side wall. The inner top of the support frame 6 is bolted with a matching cylinder 76, and the end face of the drive rod of the matching cylinder 76 is connected to the top of the mounting plate 71. When the clamping cylinder 72 is activated, its drive rod drives the end face connecting plate 73 to move, thereby pressing and fixing the bottom pressure plate 74 to the PCB board body 5. Activating the matching cylinder 76 can cooperate with the side pushing mechanism 3 to keep the clamping mechanism 7 pressed on the PCB board body 5, preventing displacement during side pushing.

[0033] In use, this invention first activates the telescopic cylinder 21, whose drive rod moves the movable plate 22 connected to the end face. The movable plate 22 then slides stably within the guide seat 222 via the slide rail 221, causing it to extend. Next, the PCB board body 5 is installed inside the positioning frame 4, and further secured with bolt locking components 42. The telescopic cylinder 21 then resets. Next, the clamping cylinder 72 is activated, whose drive rod moves the connecting plate 73 at the end face, thereby pressing and fixing the PCB board body 5 with multiple protective components 743 on the bottom pressure plate 74. Two positioning pins 742 are then inserted into the positioning... The interior of sleeve 41 is reinforced. Then, the side-push cylinder 31 and the cooperating cylinder 76 are activated. The drive rod of the side-push cylinder 31 drives the push plate 32 on the end face to move, so that the push plate 32 can drive the PCB board body 5 on the top to perform electrical connection test with the relevant test equipment interface. The drive rod of the cooperating cylinder 76 drives the mounting plate 71 to slide stably on the guide rail 712 through the slide block 711. This, together with the side-push mechanism 3, presses and stabilizes the PCB board body 5 after it is pressed, thereby completing the test operation. Finally, the pressing mechanism 7 and the side-push mechanism 3 are reset, and the telescopic mechanism 2 extends and removes the PCB board body 5 after the test.
