Description
Technical Field
[0001] This utility model relates to the field of electronic component testing technology, and in particular to a clamping head for testing the resistance of electronic components. Background Technology
[0002] In the manufacturing of semiconductor memory modules, the accurate use of each microelectronic component is crucial. The packaging of these components contains relevant information. If the actual capacitance / resistance values of a component do not match the values required for the memory module manufacturing process, the manufacturing equipment may not detect this in time, leading to a risk of product failure.
[0003] The existing technical solutions have the following drawbacks: they cannot quickly clamp some small electronic components, or the clamping force is too large, making it difficult to connect them. Utility Model Content
[0004] The purpose of this invention is to provide a clamping head for testing the resistance of electronic components, so as to solve the problems existing in the prior art.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] A clamping head for testing the resistance of electronic components includes a resistance testing device and a clamping device. The clamping device is electrically connected to the resistance testing device via a wiring harness and is used to clamp the component to be tested. The clamping device includes a fixed plate, a horizontal plate, and limiting slide rails. Two limiting slide rails are provided, symmetrically arranged on the right side of the fixed plate. The horizontal plate is detachably installed on the right side of the fixed plate. Pressure blocks are spaced apart on the right side of the fixed plate. Slider blocks are fixedly installed on both the front and rear sides of the pressure blocks, and the sliders are slidably installed on the corresponding limiting slide rails.
[0007] By adopting the above technical solution, the fixing plate needs to be fixedly installed on the workbench. The fixing plate, pressure block and horizontal plate are all made of insulating material. When testing components, the corresponding positioning block is fixedly installed on the right side of the fixing plate. The positioning block is used to position the component to be tested. Then, the wire is fixedly installed on the top of the horizontal plate. The pins of the component to be tested are generally very long, so the pins of the component to be tested pass through the horizontal plate and are located above the wire. Then, the pressure block is pressed down to realize the electrical connection between the pin and the wire.
[0008] In a further embodiment, the top of the horizontal plate is provided with a plurality of receiving slots, each receiving slot having a wire harness fixedly installed therein, and the top of the horizontal plate is provided with a plurality of metal plates at equal intervals from front to back, the metal plates being electrically connected to the corresponding wire harnesses.
[0009] By adopting the above technical solution, the metal sheet can increase the contact area, so that the pin can be better electrically connected to the wire after passing through the fixing plate, without having to consider the pin skew.
[0010] In a further embodiment, a linear drive motor is fixedly installed at the top right side of the fixing plate, and the linear drive motor is used to drive the pressing block to move up and down.
[0011] In a further embodiment, a front-to-back sliding groove is provided at the middle left side of the fixing plate, which divides the fixing plate into an upper half and a lower half. The upper half and the lower half of the fixing plate are fixedly connected by two arc-shaped bends located on the right side. An avoidance groove corresponding to the sliding groove is provided on the left side of the limiting slide rail.
[0012] By adopting the above technical solution, electronic components enter from the rear side of the slide and exit from the front side of the slide.
[0013] In a further embodiment, a guide rail is fixedly installed at the rear end of the chute, a material discharge rail is provided at the front end of the chute, a support plate is fixedly installed on the left side of the fixed plate, the top surface of the support plate is lower than the bottom surface of the chute, a receiving groove is provided at the top of the support plate, and a limiting device is installed inside the receiving groove.
[0014] By adopting the above technical solution, the part to be tested slides into the rear side of the slide groove via the guide rail, and then slides from back to front under the action of the limiting device. When it passes through the test area, the pressure block presses down. After the test is completed, the limiting device continues to move, pushing the part to be tested out of the slide groove from the front side.
[0015] In a further embodiment, the limiting device includes a conveyor belt and a lifting cylinder. The lifting cylinder is fixedly installed on the front side of the fixed plate, and the conveyor belt is fixedly installed in the receiving groove. The top of the conveyor belt is flush with the top of the support plate, and a vertically upward baffle is provided on the left side of the support plate.
[0016] By adopting the above technical solution, the telescopic rod of the lifting cylinder is located at the bottom, and the lifting cylinder is used to prevent the components on the guide rail from sliding out. A buffer pad is fixedly installed at the bottom of the lifting cylinder.
[0017] In summary, this utility model has the following beneficial effects:
