Description

Technical Field

[0001] This utility model relates to the field of circuit board testing fixture technology, and in particular to a touch-type circuit board testing fixture. Background Technology

[0002] Circuit boards are one of the most important electronic components in the electronics industry. After production, circuit boards usually need to be tested for capacitive touch functionality. The existing testing method is to fix the circuit board on a workbench, power it on, and then manually touch the capacitive buttons one by one to test the circuit board. However, this testing method can only test one circuit board at a time, and the operator needs to touch the capacitive buttons once for each test. This testing method is not only very troublesome but also inefficient. Therefore, a touch-type circuit board testing fixture was designed to solve the above problems. Utility Model Content

[0019] A touch circuit board testing fixture includes a workbench 1, a vertical support 2, a limiting plate 3, a detection bracket 4, detection components 5, a sliding column 6, a V-shaped support 7, an L-shaped drive arm 8, a linkage rod 9, and a drive column 10. The workbench 1 has a limiting plate 3 and a vertical support 2 on its end face. The vertical support 2 has a V-shaped support 7 at its top center. The bottom extension 71 of the V-shaped support 7 is slidably connected to the drive column 10. The sliding path of the drive column 10 is perpendicular to the plane of the workbench 1. The top extension 72 of the V-shaped support 7 is hinged to the outer end of the short limb of the L-shaped drive arm 8. The right angle of the L-shaped drive arm 8 is hinged to one end of the linkage rod 9. The other end of the linkage rod 9 is hinged to the top of the drive column 10. The bottom of the drive column 10 has a detection bracket 4. The sliding column 6 is vertically arranged inside the vertical support 2 to guide the sliding of the detection bracket 4. Multiple detection components 5 are evenly spaced inside the detection bracket 4.

[0020] The end face of the limiting plate 3 has a limiting groove 31 for positioning the circuit board. The limiting groove 31 has a rubber layer for buffering. The limiting grooves 31 are evenly distributed on the end face of the limiting plate 3. The limiting grooves 31 are arranged below the detection component 5.

[0021] The detection bracket 4 has a positioning plate 41, a driving plate 42 and a connecting column 43. The positioning plate 41 and the driving plate 42 are fixedly connected by a plurality of connecting columns 43 set on the edge. One side of the positioning plate 41 is slidably connected to the sliding column 6. The end face of the positioning plate 41 is provided with a plurality of equally spaced detection components 5. The top end of the driving plate 42 is fixedly connected to the bottom end of the driving column 10.

[0022] The detection component 5 has a capacitive touch head 51, a data transmission plug 52 and a spring 53. The capacitive touch head 51 is used to emit touch signals, the data transmission plug 52 is used to supply power and transmit data, and the spring 53 is sleeved on the capacitive touch head 51 and fixedly connected to the positioning. The spring 53 is used to separate the circuit board from the data transmission plug 52.

[0023] The workbench 1 has a double start button 11 on one side of its top surface and a power switch 12 on the other side of its top surface. The workbench 1 has a display screen 13 on its front surface for displaying the corresponding circuit board test values. The number of display screens 13 is the same as the number of limit slots 31.

[0024] With the above settings, its specific working principle in actual operation is as follows:

[0025] First, place the circuit board to be tested into the limiting groove 31 on the end face of the limiting plate 3. Then, pull down the L-shaped drive arm 8. The L-shaped drive arm 8 drives the drive column 10 to move downward through the linkage rod 9. During the downward movement, the drive column 10 drives the positioning plate 41 in the testing bracket 4 to approach the limiting plate 3. When the positioning plate 41 is completely in contact with the limiting plate 3, the data transmission plug 52 is inserted into the circuit board socket, the capacitive touch head 51 is in contact with the circuit board touch switch, and the spring 53 is compressed at the same time.

[0026] Then press the dual start button 11, the circuit board is powered on and starts to run. Since the capacitive touch head 51 touches the circuit board, the data transmission plug 52 sends the touch button feedback data to the display screen 13. The tester observes the data displayed on the display screen 13 to test the touch function of the circuit board.

[0027] After the test is completed, the L-shaped drive arm 8 is lifted upward. The L-shaped drive arm 8 drives the drive column 10 to move upward through the linkage rod 9. During the upward movement of the drive column 10, the positioning plate 41 in the test bracket 4 moves away from the limit plate 3. During this process, the spring 53 forces the data transmission plug 52 to be removed from the circuit board socket, so that the circuit board can be easily removed after the test is completed.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
