Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig for detecting circuit boards with a positioning mechanism. Background Art

[0002] The washing machine control board can be called an electronic control circuit board, which is a type of circuit board. The circuit board is a plate-like object based on printed circuit technology. It provides electrical connections between electronic devices and is an indispensable part of various electronic devices. The main function of the washing machine control board is to control the various operations of the washing machine through the electronic components on the circuit board, so it can also be classified as a circuit board.

[0003] Current circuit board inspection jigs with positioning mechanisms basically clamp the two ends of the circuit board using a clamping tool. Only after the clamping is fixed can it be inspected by an inspection device. However, the existing clamping tools cannot clamp circuit boards of different sizes. Moreover, when multiple circuit boards are inspected in sequence, the bolts and other accessories on the clamping tools need to be removed before the next circuit board can be clamped, which reduces the speed of the inspection work. Therefore, a circuit board inspection jig with a positioning mechanism is proposed to solve the above problems. Utility Model Content

[0004] In view of the deficiencies in the prior art, the present invention provides a circuit board inspection jig with a positioning mechanism, which is used to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A jig for detecting circuit boards with a positioning mechanism comprises a base plate, a through hole being opened on the base plate, a fixing plate being fixedly mounted on an inner wall of one side of the through hole, a connecting plate being fixedly mounted on one side of the fixing plate, a first connecting seat being fixedly mounted on the top side of the fixing plate, a linkage plate being movably sleeved in the first connecting seat, the other end of the linkage plate being movably sleeved on the first connecting column, two long rods being movably sleeved on the outer side of the first connecting column, the other ends of the two long rods being movably sleeved on the second connecting column, a third connecting seat being fixedly mounted on one side of the fixing plate, a connecting block being movably arranged in the third connecting seat, the other end of the connecting block being movably sleeved in the second connecting column, a guide assembly being arranged on the connecting plate, a linkage assembly being arranged between the connecting block and the fixing plate, and a detector being arranged above the base plate.

[0007] Preferably, the guide assembly includes a connecting plate with sliding grooves on both sides, and sliders are slidably arranged in the two sliding grooves. The sides of the two sliders that are away from each other are fixedly connected to the same fixed block, and the fixed block is U-shaped.

[0008] Preferably, the linkage assembly includes a side plate fixedly mounted on one side of the fixed plate, the side plate is arranged at an angle, two springs are fixedly mounted on one side of the side plate, and the other ends of the two springs are fixedly connected to the top side of the connecting block.

[0009] Preferably, a second connecting seat is fixedly installed on one side of the fixing block, two short rods are movably sleeved in the second connecting seat, and the other ends of the two short rods are movably sleeved on the first connecting column.

[0010] Preferably, a movable splint is fixedly installed on one side of the fixed block, the bottom side of the movable splint contacts the top side of the base plate, a fixed splint is fixedly installed on the top side of the base plate, and a protective pad is fixedly installed on the side where the fixed splint and the movable splint are close to each other.

[0011] Preferably, a mounting bracket is fixedly mounted on the top side of the base plate, and a detector is fixedly mounted on the bottom side of the mounting bracket, with the detector facing the base plate.

[0012] Preferably, a pressing plate is fixedly mounted on the top side of the connecting block, and the pressing plate is located below the bottom plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the circuit board detection jig with a positioning mechanism can drive the two long rods to move downward by stepping on the pressure plate, thereby causing the first connecting column to move downward synchronously. When the first connecting column moves downward, the two short rods move toward the fixed clamping plate, and then the movable clamping plate on one side of the fixed block moves toward the fixed clamping plate, so that the circuit board can be clamped. When testing circuit boards with larger volumes, the distance between the movable clamping plate and the fixed clamping plate can be adjusted simply by stepping on the pressure plate, thereby achieving clamping of circuit boards of different sizes. When testing circuit boards, personnel can sit on a stool to operate, avoiding physical discomfort caused by standing for a long time.

[0014] Through the provided side plates and springs, after the inspection is completed, the personnel removes their feet from the pressure plate, and under the action of the two springs, the connecting block moves upward. When the connecting block moves upward, it drives the two long rods to move the first connecting column upward. The upward movement of the first connecting column can drive the two short rods to drive the second connecting seat to move backward, thereby resetting the movable splint. After resetting, the next circuit board can be clamped. BRIEF DESCRIPTION OF THE DRAWINGS

A mounting bracket 2 is fixedly installed on the top side of the base plate 1, and a detector 3 is fixedly installed on the bottom side of the mounting bracket 2. The detector 3 faces the base plate 1. By placing the circuit board between the fixed clamping plate 4 and the movable clamping plate 22, and then stepping on the pressure plate 21 with your foot, the two long rods 15 can be driven to move downward, so that the first connecting column 11 moves downward synchronously. When the first connecting column 11 moves downward, the two short rods 12 move toward the fixed clamping plate 4, thereby driving the movable clamping plate 22 on one side of the fixed block 13 to move toward the fixed clamping plate 4, so that the circuit board can be clamped, and the protective pad 23 provided can avoid damage to both sides of the circuit board when clamping the circuit board. After clamping, the circuit board can be detected by the detector 3.

[0022] Specifically, the guide assembly includes a connecting plate 6, both sides of which are provided with a slide groove 7, and a slider 8 is slidably provided in the two slide grooves 7. The two sliders 8 are fixedly connected to the same fixed block 13 on the side away from each other. The fixed block 13 is U-shaped, and a second connecting seat 14 is fixedly installed on one side of the fixed block 13. Two short rods 12 are movably sleeved in the second connecting seat 14, and the other ends of the two short rods 12 are movably sleeved on the first connecting column 11. A movable splint 22 is fixedly installed on one side of the fixed block 13, and the bottom side of the movable splint 22 is in contact with the top side of the bottom plate 1, and a fixed splint 4 is fixedly installed on the top side of the bottom plate 1, and the fixed splint 4 and the movable splint 22 are fixed on the side close to each other. A protective pad 23 is fixedly installed, and a pressure plate 21 is fixedly installed on the top side of the connecting block 17. The pressure plate 21 is located below the bottom plate 1. Through the two sliders 8, when the pressure plate 21 is cyclically stepped on to drive the first connecting column 11 to move up and down, the two short rods 12 will synchronously drive the second connecting seat 14 to move back and forth. When the second connecting seat 14 drives the fixed block 13 to move back and forth, the two sliders 8 slide in the two slide grooves 7, which can provide guiding and limiting functions when the movable splint 22 moves, so that it will not deviate from the pre-moving trajectory when moving, and the protective pad 23 can be set to prevent the two sides of the circuit board from being clamped when clamping the circuit board.

[0023] Specifically, the linkage assembly includes a side plate 19 fixedly installed on one side of the fixed plate 5, and the side plate 19 is arranged at an angle. Two springs 20 are fixedly installed on one side of the side plate 19, and the other ends of the two springs 20 are fixedly connected to the top side of the connecting block 17. Through the two springs 20, after the inspection is completed, the personnel removes their feet from the pressure plate 21. Under the action of the two springs 20, the connecting block 17 moves upward, and then the movable splint 22 is reset, so that another circuit board can be inspected. When inspecting the circuit board, the personnel can sit on a stool to operate, avoiding physical discomfort caused by standing for a long time.

[0024] In use: When the circuit board needs to be tested, the circuit board is placed between the fixed clamping plate 4 and the movable clamping plate 22, and then the pressure plate 21 is stepped on with the foot, which can drive the two long rods 15 to move downward, thereby causing the first connecting column 11 to move downward synchronously. When the first connecting column 11 moves downward, the two short rods 12 move toward the fixed clamping plate 4, and then the movable clamping plate 22 on one side of the fixed block 13 moves toward the fixed clamping plate 4, so that the circuit board can be clamped. The protective pad 23 provided can avoid damage to both sides of the circuit board when clamping the circuit board. After clamping, the circuit board can be inspected by the detector 3. After the inspection is completed, the person removes his foot from the pressure plate 21. Under the action of the two springs 20, the connecting block 17 moves upward, and then the movable splint 22 is reset. When inspecting a larger circuit board, the distance between the movable splint 22 and the fixed splint 4 can be adjusted by stepping on the pressure plate 21, thereby achieving clamping of circuit boards of different sizes. When inspecting the circuit board, the person can sit on a stool to operate, avoiding physical discomfort caused by standing for a long time.
