Description

Technical Field

[0001] This utility model relates to the field of PCB board production technology, specifically to an inspection device for PCB board production. Background Technology

[0002] In the process of PCB board production and processing, in order to ensure product quality, it is necessary to test the strength of the PCB board. Usually, pressure is applied to the PCB board to test whether its strength is qualified.

[0003] According to a public notice of an inspection device for PCB board production (Announcement No.: CN221445669U), the PCB board to be inspected is placed on top of the placement plate. Under the action of a spring, the pressure plate is pushed down to reset, so that the pressure plate plays a stable clamping and positioning role for the PCB board to be inspected.

[0004] However, in actual use, the PCBs of the above-mentioned equipment have different shapes and sizes, and the fixing fixture can only perform fixed inspection on fixed PCBs, resulting in poor inspection effect for multiple PCBs; in view of this, we propose an inspection device for PCB production. Utility Model Content

[0005] The purpose of this invention is to provide an inspection device for PCB board production, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an inspection device for PCB board production, comprising a mounting platform, a fixing frame fixedly mounted on the surface of the mounting platform, an electric push rod fixedly mounted on the upper surface of the fixing frame, a pressure sensor fixedly mounted on the movable end of the electric push rod, a positioning mechanism provided on the upper surface of the mounting platform, and a promoting mechanism provided on the upper surface of the mounting platform, the positioning mechanism comprising:

[0007] The motor is fixedly mounted on the side wall of the mounting platform. A lead screw is fixedly mounted on the output end of the motor. A sliding seat is connected to the arc-shaped thread of the lead screw. A threaded block is movably connected to the upper surface of the sliding seat. A threaded rod is threaded to the inner wall of the threaded block.

[0008] A fixed block is movably connected to the end of a threaded rod. A roller is movably connected to the inner wall of the fixed block. An air bladder is fixedly installed on the surface of the roller, and a friction ring is fixedly installed on the arc surface of the air bladder.

[0009] Preferably, the promoting mechanism includes a movable groove, which is formed on the surface of the fixed block. A straight rod is fixedly installed on the inner wall of the movable groove. A torsion spring is fixedly connected to the arc surface of the straight rod, and the end of the torsion spring away from the arc surface of the straight rod is fixedly connected to the inner wall of the centering plate.

[0010] Preferably, the centering plate has a rotating hole on its surface, the diameter of which is adapted to the diameter of the straight rod, and the centering plate is fitted onto the arc surface of the straight rod, so that the centering plate can rotate on the surface of the straight rod.

[0011] Preferably, the surface of the fixing block is provided with a groove, the shape of which is adapted to the shape of the roller.

[0012] Preferably, the number of rollers is set to several, and the several rollers are arranged in a linear array on the surface of the fixed block. The multiple rollers ensure that the PCB board is stably moved to a suitable position for testing.

[0013] Preferably, there are two sliding seats, which are arranged in a mirror image on the arc surface of the lead screw, so that the rotation of the lead screw drives the two sliding seats to move synchronously.

[0014] Preferably, the surface of the sliding seat is provided with a through hole, the diameter of which is adapted to the diameter of the threaded rod, and the threaded rod passes through the sliding seat, so that the threaded rod moves on the surface of the sliding seat.

[0015] Compared with the prior art, this utility model provides an inspection device for PCB board production, which has the following beneficial effects:

[0016] 1. This inspection device for PCB board production includes a positioning mechanism. A motor drives a lead screw to rotate, causing a sliding block to slide. The position of the sliding block is adjusted to accommodate different PCB board shapes. Further rotation of the threaded block moves the threaded rod up and down, causing a fixed block to move up and down as well. This ensures the fixed block limits the height of the PCB board, allowing the PCB board to move along the surface of the fixed block. Simultaneously, the rollers facilitate the sliding of the PCB board along the mounting table surface. Friction rings and air pockets on the roller surface ensure better contact between the rollers and the PCB board surface, resulting in better positioning of the PCB board on the mounting table surface.

[0017] 2. This inspection device for PCB board production, by setting up a facilitating mechanism, allows two centering plates to rotate under the setting of torsion springs. The centering plates can limit the edge of the PCB board, and the rotation of the centering plates can achieve a centering positioning effect for the PCB board, ensuring the PCB board is centered on the mounting table surface.

Detailed Implementation

[0024] like Figures 1-5 As shown, this utility model provides a technical solution: an inspection device for PCB board production, including a mounting platform 1, a fixing frame 2 fixedly mounted on the surface of the mounting platform 1, an electric push rod 5 fixedly mounted on the upper surface of the fixing frame 2, a pressure sensor 6 fixedly mounted on the movable end of the electric push rod 5, a positioning mechanism 3 provided on the upper surface of the mounting platform 1, and a promoting mechanism 4 provided on the upper surface of the mounting platform 1. The positioning mechanism 3 includes a motor 301, a lead screw 302, a sliding seat 303, a threaded block 304, a threaded rod 305, a fixing block 306, a roller 307, an airbag 308, and a friction ring 309.

[0025] In one embodiment of this utility model, a motor 301 is fixedly installed on the side wall of the mounting platform 1. A lead screw 302 is fixedly installed at the output end of the motor 301. A sliding seat 303 is threadedly connected to the arc surface of the lead screw 302. A threaded block 304 is movably connected to the upper surface of the sliding seat 303. A threaded rod 305 is threadedly connected to the inner wall of the threaded block 304. A fixing block 306 is movably connected to the end of the threaded rod 305. A roller 307 is movably connected to the inner wall of the fixing block 306. An airbag 308 is fixedly installed on the surface of the roller 307. A friction ring 309 is fixedly installed on the arc surface of the airbag 308.

[0026] In addition, the promoting mechanism 4 includes a movable groove 401, which is formed on the surface of the fixed block 306. A straight rod 402 is fixedly installed on the inner wall of the movable groove 401. A torsion spring 403 is fixedly connected to the arc surface of the straight rod 402. The end of the torsion spring 403 away from the arc surface of the straight rod 402 is fixedly connected to the inner wall of the centering plate 404. A rotating hole is formed on the surface of the centering plate 404. The diameter of the rotating hole is adapted to the diameter of the straight rod 402. The centering plate 404 is sleeved on the arc surface of the straight rod 402, so that the centering plate 404 can rotate on the surface of the straight rod 402.

[0027] In this embodiment of the invention, the surface of the mounting platform 1 is provided with an adjustment groove, the shape of which is adapted to the shape of the lead screw 302. One end of the lead screw 302 is movably connected to the surface of the adjustment groove, and the other end of the lead screw 302 is fixedly connected to the output end of the motor 301. The surface of the fixing block 306 is provided with a groove, the shape of which is adapted to the shape of the roller 307, allowing the roller 307 to rotate inside the groove. The roller 307 is movably connected to the inner wall of the groove via a connecting shaft. Several rollers 307 are arranged in a linear array on the surface of the fixing block 306. The multiple rollers 307 ensure that the PCB board is stably moved to a suitable position for testing. Two sliding seats 303 are provided. Two sliding seats 303 are arranged in a mirror image on the arc surface of the lead screw 302. The rotation of the lead screw 302 drives the two sliding seats 303 to move synchronously, limiting the two sides of the PCB board. The surface of the sliding seat 303 has a through hole, the diameter of which matches the diameter of the threaded rod 305. The threaded rod 305 passes through the sliding seat 303, causing the threaded rod 305 to move on the surface of the sliding seat 303, driving the fixed block 306 to move. The fixed block 306 is limited by the sliding seat 303. The pressure sensor 6 utilizes the piezoelectric effect. When external pressure is applied, the piezoelectric sheet inside the sensor will bend and deform. This deformation will cause a change in the distribution of charge inside the piezoelectric sheet, thereby generating a potential difference, which in turn generates a detectable electrical signal.

[0028] In this invention, during use, the motor 301 starts and drives the lead screw 302 to rotate, which in turn causes the sliding seat 303 to slide. The position of the sliding seat 303 is then adjusted according to the different shapes of the PCB board. Further rotation of the threaded block 304 causes the threaded rod 305 to move up and down, which in turn causes the fixing block 306 to move up and down, ensuring that the fixing block 306 limits the height of the PCB board. This allows the PCB board to move along the surface of the fixing block 306. At the same time, the roller 307 facilitates the sliding of the PCB board along the surface of the mounting platform 1. The friction ring 309 and airbag 308 on the surface of the roller 307 allow the roller 307 to better fit the surface of the PCB board, thus better positioning the PCB board on the surface of the mounting platform 1.

[0029] Furthermore, with the torsion spring 403 in place, the two centering plates 404 can rotate on the straight rod 402 to limit the edge of the PCB board. The centering plates 404 can rotate on the straight rod 402 to achieve a centering positioning effect on the PCB board, ensuring the PCB board is centered on the surface of the mounting platform 1. The electric push rod 5 drives the pressure sensor 6 to detect the pressure on the surface of the PCB board and obtain the corresponding data.

[0030] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
