Description

Technical Field

[0001] The invention relates to the technical field of PCB board testing, and in particular to an in-and-out pressing structure for PCB board testing. Background Art

[0002] In the field of PCB technology, PCB board testers need to perform short-circuit tests first and then functional tests. Traditional PCB testers usually place the circuit board to be tested on top of the test fixture, then manually press the start button and the cylinder is pressed down for testing. As some products have higher components on the top, it is inconvenient to place them manually under the cylinder. At present, there are many automated tests introduced in the testing field, and most of them use robots to pick up and place the products under test. If the original method of placing them under the downward pressure cylinder is adopted, a 6-axis robot is required, and the production cost is relatively high. Utility Model Content

[0003] In order to solve the technical defects raised in the above-mentioned background technology, the purpose of the utility model is to provide a PCB board test in-and-out pressing structure, which can place the PCB circuit board to be tested outside the pressing component. After the placement is completed, press the start button, and the mobile component will send the product to the bottom of the pressing cylinder, and then the pressing cylinder will press down. Only a three-axis manipulator is needed to complete the picking and placing action, which is not only convenient for users to operate, but also can save the cost of automated production.

[0004] The utility model adopts the following technical scheme: a PCB board test in-and-out downward pressing structure, including a mounting table panel, the mounting table panel is provided with a slide rail, a moving component and a horizontal cylinder, the slide rail is installed at both ends of the mounting table panel, and the moving component is slidably installed above the slide rail and connected to the horizontal cylinder.

[0005] By adopting the above technical solution, the mobile component can send the product to the bottom of the pressing component to realize the pressing test, which is convenient for users to operate and saves production costs.

[0006] Furthermore, the moving assembly includes a C-shaped support plate, a needle guard plate and a lifting rod, one end of the lifting rod is connected to the needle guard plate, and the other end of the lifting rod is connected to the C-shaped support plate. A slider is provided under the C-shaped support plate, and the slider is adapted to the slide rail.

[0007] By adopting the above technical solution, the slider is slidably connected to the slide rail, thereby driving the horizontal movement of the entire moving assembly.

[0008] Furthermore, a mounting block is provided on the side of the C-shaped support plate, and the horizontal cylinder is connected to the mounting block.

[0009] By adopting the above technical solution, the horizontal cylinder pushes the C-type pallet to move on the slide rail, providing power for the operation of the moving component.

[0010] Furthermore, the lifting rod is also provided with a spring.

[0011] By adopting the above technical solution, a spring is arranged on the lifting rod, so that the needle guard plate can be elastically lifted and lowered.

[0012] To sum up, the beneficial effects of the utility model are as follows: by arranging slide rails, moving components and horizontal cylinders on the mounting table panel, the slide rails are installed at both ends of the mounting table panel, and the moving components are slidably installed above the slide rails and connected to the horizontal cylinder, so that the moving components can autonomously send the product to the bottom of the pressing component to realize the pressing test, which is convenient for user operation and also saves production costs.

[0013] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention, it can be implemented in accordance with the contents of the specification.
