However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a detection device for a circuit board, comprising: a fixed frame 1, a first electric telescopic rod 3 is arranged on the top of the fixed frame 1, the telescopic end of the first electric telescopic rod 3 slides through the top of the fixed frame 1, the telescopic end of the first electric telescopic rod 3 is fixedly connected with a fixed component 2, and the inner top of the fixed frame 1 is fixedly connected with a plug-in component 4; a fixed component 2, the fixed component 2 comprises a first connecting block 201, the first connecting block 201 is fixedly connected to the telescopic end of the first electric telescopic rod 3, the inner surface of the first connecting block 201 is slidably connected with connecting rods 202 near four corners, the bottoms of the plurality of connecting rods 202 are fixedly connected with connecting plates 206, the outer surfaces of the plurality of connecting rods 202 are respectively sleeved with other springs 205, the bottom center of the first connecting block 201 is fixedly connected with a fixing block 204, and the fixing block 204 and the connecting plate 206 are matched. The plug-in assembly 4 includes a mounting frame 401, which is fixedly connected to the inner top of the fixing frame 1. A second electric telescopic rod 402 is arranged at the center of the inner bottom of the mounting frame 401. The telescopic end of the second electric telescopic rod 402 slides through the inner bottom of the mounting frame 401. The telescopic end of the second electric telescopic rod 402 is fixedly connected to a second connecting block 404. A plurality of mounting rods 405 are fixedly connected to the bottom of the second connecting block 404 at equal intervals. The bottoms of the plurality of mounting rods 405 are all fixedly connected to mounting blocks 406. A contact block 407 is arranged at the bottom of the mounting block 406. The spring 205 is located between the relative outer surfaces of the connecting plate 206 and the first connecting block 201, and the spring 205 and the connecting plate 206 are arranged in a matching manner. A limit block 203 is fixedly connected to the outer surface of the connecting rod 202 near the top, and the limit block 203 is arranged in a matching manner with the first connecting block 201. A buffer block 207 is arranged at the bottom of the connecting plate 206, and the thickness of the buffer block 207 is greater than the thickness of the connecting plate 206.

[0023] The effect achieved by the entire embodiment 1 is that when the circuit board is tested, the circuit board to be tested is first placed inside the placement block 5, and the inner surface of the placement block 5 is in contact with the surrounding surfaces of the circuit board, which plays a positioning role. The first electric telescopic rod 3 set at the top center of the fixing frame 1 is started. When the telescopic end of the first electric telescopic rod 3 extends downward, it will drive the first connecting block 201 to move downward synchronously. When the buffer block 207 set below it contacts the surface of the circuit board, the first connecting block 201 will slide down along the surface of the multiple connecting rods 202 and The plurality of springs 205 are squeezed to deform and shrink, and the springs 205 are elastically reset to cause them to continue to stretch outward, respectively squeezing the connecting plate 206 and the first connecting block 201, playing a buffering role. The limit blocks 203 fixed on the outer surfaces of the plurality of connecting rods 202 are used to limit the first connecting block 201. When the first connecting block 201 is continuously pushed, the fixed block 204 fixed at the bottom center of the first connecting block 201 gradually contacts the connecting plate 206, so that the buffer block 207 can The board is tightly abutted and fixed, and then the second electric telescopic rod 402 is started. When the output end of the second electric telescopic rod 402 extends downward in the mounting frame 401, it pushes the second connecting block 404, and drives the mounting block 406 to move downward accordingly through multiple mounting rods 405, so that the contact block 407 arranged at the bottom thereof can be inserted into the reserved interface on the surface of the circuit board, and the circuit board is powered on for testing. For example, the surface of a partially functional circuit board has an indicator light and a sound unit. After power is turned on, observe whether the functional characteristics of such circuit boards are working normally. The first electric telescopic rod 3 drives the first connecting block 201 to drive the buffer block 207 arranged below the connecting plate 206 to abut against the surface of the circuit board, which plays a fixing role. The second electric telescopic rod 402 then drives the second connecting block 404, so that the contact block 407 arranged at the bottom thereof can be plugged in and out of the reserved opening of the circuit board, replacing the manual plug-in and pull-out test. The manual work only needs to take and place the circuit board to assist in observing whether the circuit is working normally after power is turned on, thereby avoiding the need for personnel to repeatedly plug and unplug the circuit board for a long time when testing the circuit boards in large quantities, thereby reducing the work intensity of the personnel.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, the top of the second connecting block 404 is symmetrically fixedly connected with a sliding rod 403, the outer surfaces of the two sliding rods 403 are slidably connected to the inner surface of the mounting frame 401, and a placement block 5 is fixedly connected at the center of the inner bottom of the fixing frame 1, and the top of the placement block 5 is symmetrically provided with a slot 6.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, by symmetrically opening the slots 6 on the top of the placement block 5, the edge of the circuit board is exposed outside the placement box without affecting the positioning and fixation of the circuit board, so that personnel can take the circuit board easily. By symmetrically fixing the slide bars 403 on the top of the second connecting block 404, the second connecting block 404 can move up and down. When the circuit board is plugged in and out, the two slide bars 403 will slide synchronously in the mounting frame 401, playing a role of limiting, preventing the contact block 407 from shifting in position during the up and down movement, affecting the plugging and unplugging of the contact block 407 in the circuit board interface, and improving the use effect of the circuit board detection device.

[0026] Working principle: During the inspection, the circuit board to be inspected is placed inside the placement block 5, which plays a positioning role. The first electric telescopic rod 3 is started. When the telescopic end of the first electric telescopic rod 3 extends downward, the first connecting block 201 is driven to move downward synchronously. When the buffer block 207 contacts the surface of the circuit board, the first connecting block 201 will slide down along the surface of multiple connecting rods 202 and squeeze multiple springs 205. The springs 205 are deformed and contracted, and the connecting plate 206 and the first connecting block 201 are reset and squeezed respectively, which plays a buffering role. Under the continuous push of the telescopic end of the first electric telescopic rod 3, the spring 205 further contracts, and the fixed block 204 fixed at the bottom center of the first connecting block 201 will gradually contact the connecting plate 206. The buffer block 207 can tightly contact and fix the circuit board, thereby playing a fixing role. When the second electric telescopic rod 402 is started, its output end will push the second connecting block 404 when it extends downward in the mounting frame 401, and drive the mounting block 406 to move downward accordingly through multiple mounting rods 405, so that the contact block 407 set at the bottom can be inserted into the reserved interface on the surface of the circuit board, and the circuit board is powered on for testing. By fixing the circuit board and plugging and unplugging the interface of the circuit board, the manual plug-in power-on test is replaced. The manual work only needs to take and place the circuit board and assist in observing whether the circuit is working normally after power-on, which avoids the need for personnel to repeatedly plug and unplug the circuit board for a long time when testing circuit boards in large quantities, thereby reducing the work intensity of personnel.

Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
