[0040] A rolling flattening assembly 3 is fixedly connected to the top of the inner wall of the installation hanging frame group 14. A control assembly 4 is fixedly connected to the top of the installation table 11.

[0041] During use, rotate the rotating cover plate 133 to the vertical direction, remove the side pressure strip 222. The operator places the circuit board to be tested in the rectangular blind hole inside the frame body 221. After placing it securely, reset the side pressure strip 222 and fix the side pressure strip 222 and the frame body 221 with a cylindrical pin. Then close the rotating cover plate 133, insert a cylindrical pin at the top of the rotating cover plate 133 to fix the rotating cover plate 133, and then start the entire detection device through the control component 4;

[0042] After the device is started, the servo electric cylinder 212 is started, and the optical rod drives the fixed frame 22 to slide backward to the rear of the device. Before the device enters below the front hanger 141, it drives the circuit board to pass through the pre-test cleaning brush 23. The nylon brush of the pre-test cleaning brush 23 removes the solid impurities existing on the upper and lower surfaces of the circuit board. Then the circuit board starts to be detected in the vertical direction through the laser distance sensor 24. After the circuit board passes below the laser distance sensor 24, the distance detection data of the laser beam transmitted back to the control component 4 changes. The control component 4 records the detection data and analyzes the surface of the circuit board to be tested. If the flatness of the surface of the circuit board to be detected meets the requirements, the servo electric cylinder 212 pushes the fixed frame 22 to pass over the rolling flattening component 3 to the back of the device. After the fixed frame 22 reaches the back of the device, the operator removes the cylindrical pin of the pre-test cleaning brush 23, pulls out the fixed frame 22 to take out the circuit board to be tested, then reinstalls and fixes the fixed frame 22, resets the pre-test cleaning brush 23 and the fixed frame 22, and continues to perform the detection of the next circuit board to be tested;

[0043] If there are parts with unqualified flatness on the surface of the circuit board to be detected, the circuit board to be tested is driven by the fixed frame 22 to enter below the rolling flattening component 3 and continues to move at a constant speed.

The surface of the rubber roller 32 is covered with a rubber layer. There are two rubber rollers 32 in total, which are used to cooperate with the electric push rod 31 to flatten the circuit board to be tested;

[0045] A rear cleaning brush 33 is fixedly connected to the back of the middle hanger 142. The rear cleaning brush 33 includes a top brush 331. The top brush 331 is fixedly connected to the top of the strip frame body 131. One side of the top brush 331 is fixedly connected to the inside of the rear hanger 143.

A nylon brush is fixedly connected to the top of the bottom brush 332. The bottom brush 332 is located at the bottom of the top brush 331 and is used to clean the measured circuit board after leveling. The rolling leveling assembly 3 flattens the unqualified parts of the surface flatness of the detected electronic components, reducing the workload of the leveling task. At the same time, it reduces the adverse impact on the electronic components during the extrusion leveling process and improves the leveling efficiency of the electronic components.

[0046] During use, when the circuit board to be measured needs to be flattened, the electric push rod 31 is controlled by the control assembly 4. When the circuit board to be measured runs to different positions, the electric push rod 31 adjusts the stroke of its polished rod, so that the rubber roller 32 makes vertical extrusion and forward and backward rolling with the surface of the circuit board to be leveled. After the leveling is completed, the circuit board to be measured passes through the rear cleaning brush 33 driven by the fixed frame 22. The nylon brush of the rear cleaning brush 33 cleans the solid impurities that may be generated during the flattening process for subsequent repeated detection.

[0047] Embodiment 3: Please refer to Figures 1-8 , on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: Laser distance sensors 24 are slidably connected to the top and bottom of the inner wall of the rear hanger 143 through trapezoidal slide rails. The laser distance sensors 24 can be fixedly connected to the trapezoidal slide rails through compression bolts. The back of the laser distance sensors 24 is electrically connected to the wire routing square tube 144 through wires and is used to detect the measured circuit board after leveling;

The horizontal power group 21 is electrically connected to one side of the electric control box 42 through a wire. The back of the electric control box 42 is electrically connected to the wire routing square tube 144 through a wire. By setting up a control mechanism, the control mechanism is used to link the rolling leveling mechanism and cooperate with the laser sensor behind the rolling leveling mechanism to realize the repeated detection of the surface flatness of the electronic components after flattening treatment, improving the detection effect of the device, and further enhancing the production efficiency and production effect of the electronic components.

[0049] In use, the operator connects the electric control box 42 to the external power distribution system, and then starts the electric control box 42 through the operation terminal 41. After placing the circuit board to be tested securely, the detection process of the first embodiment is started. During the detection process, the laser distance sensor 24 located on the front hanger 141 transmits the detection data back to the electric control box 42. After processing the transmitted detection data, the electric control box 42 displays the data and results on the display screen of the operation terminal 41 for the operator to monitor and adjust. When it is necessary to perform the flattening process in the second embodiment, the electric control box 42 adjusts the stroke of the electric push rod 31 in real time according to the feedback signal of the laser distance sensor 24 and the stroke signal feedback from the servo electric cylinder 212 to the electric control box 42, so as to achieve precise flattening treatment of the unqualified parts of the flatness of the surface of the circuit board to be tested. After the circuit board to be tested leaves the rolling flattening assembly 3, the circuit board to be tested passes through the laser distance sensor 24 on the rear hanger 143, and the laser distance sensor 24 on the rear hanger 143 feeds back the repeated detection data to the electric control box 42. If the detection result after flattening reaches the qualified standard, the electric control box 42 controls the servo electric cylinder 212 to drive the circuit board to be tested to the back of the device to complete the detection and flattening process. If the detection result still does not reach the qualified standard, the electric control box 42 controls the servo electric cylinder 212 to contract the optical rod, brings the fixed frame 22 back under the rolling flattening assembly 3, and repeats the flattening process in the second embodiment for the circuit board to be tested until the detection result meets the requirements.
