Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 2, the present invention provides a multilayer circuit board testing device, which is used for performing a circuit test on a circuit board, wherein heat dissipation holes are formed in the circuit board, the multilayer circuit board testing device includes a base 20, an upper seat 10 and a driving device, the upper seat 10 is connected with the driving device, and the driving device drives the upper seat 10 to move in a vertical direction.
The upper seat 10 is provided with an installation seat 30, a position detection module 40 and a test module 50, the installation seat 30 is arranged at the position close to the bottom of the upper seat 10, the position detection module 40 and the test module 50 are arranged on the installation seat 30, the test module 50 comprises a probe 51 and a detection plate, and the detection plate detects the circuit board through the probe 51.
The position detection module 40 includes a housing 41, an ejector pin 44, a return spring 43 and a pressure sensor 42, the ejector pin 44 is movably mounted on the housing 41, the bottom end of the ejector pin 44 extends out of the housing 41, a stressed seat 45 is arranged at the top of the ejector pin 44, the ejector pin 44 is limited by the stressed seat 45 and cannot completely slide out of the housing 41, the pressure sensor 42 and the return spring 43 are mounted in the housing 41, and two ends of the return spring 43 respectively abut against the pressure sensor 42 and the stressed seat 45.
The utility model also comprises a system controller, wherein the driving device, the pressure sensor 42 and the detection plate are all connected to the system controller, the pressure sensor 42 feeds detected pressure information back to the system controller, the detection plate feeds detected circuit information back to the system controller, and the system controller controls the driving device to work.
When the circuit board detection device works, part of radiating holes in the circuit board (no through holes are required around the circuit board) are selected, the circuit board is transferred onto the base 20 by an external manipulator, the driving device drives the upper seat 10 to press downwards, the position detection module 40 is aligned with the detection holes in the circuit board in the vertical direction for correctly placing products, the material transfer device 30 grabs the circuit board downwards, if the position model or the placing position of the circuit board is correct, the ejector pins 44 of the position detection module 40 penetrate through the radiating holes, and the detection pressure of the pressure sensor 42 does not reach a set value, the system controller judges that the model or the placing position of the circuit board is correct, and the detection plate detects whether the circuit on the circuit board is qualified; on the contrary, when the circuit board is placed incorrectly, part of the ejector pins 44 or all of the ejector pins 44 cannot penetrate through the heat dissipation holes, the corresponding ejector pins 44 are pressed downwards, the return springs 43 elastically contract and squeeze the pressure sensors 42, and the detection pressure of the pressure sensors 42 reaches a set value, so that the system controller judges that the circuit board is placed incorrectly, the detection plate does not perform detection operation, and sends an alarm to inform a worker.
The multilayer circuit board testing device has the beneficial effects that: set up position detection module 40 on the basis through test module 50, judge earlier whether the position of circuit board is placed correctly by position detection module 40, carry out test operation again, prevent that circuit board offset from causing the erroneous judgement, and then guarantee the exactness of test, the practicality is strong.
The above-described embodiments only represent one embodiment of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the utility model. It should be noted that, for those skilled in the art, many variations and modifications can be made without departing from the spirit of the utility model, and these are within the scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
