[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods:

[0021] like Figure 1-2 As shown, the utility model provides a clamping device for circuit board testing, including a testing platform 1, wherein sliding holes 101 penetrating the upper and lower surfaces of the testing platform 1 are provided on both the left and right sides of the middle portion of the surface of the testing platform 1, and square holes 102 penetrating the testing platform 1 are provided on both the front and rear sides of the two sliding holes 101 on the left and right surfaces.

A movable plate 205 is fixedly connected, and the lower surface of the movable plate 205 is movably connected to the upper surface of the detection table 1. A plurality of through holes 206 are provided on the surface of the movable plate 205 and pass through the left and right surfaces. Fixed blocks 207 are fixedly connected to the front and rear sides of the lower surface of the movable plate 205. The outer walls of the front and rear fixed blocks 207 are movably connected to the inner walls of the front and rear square holes 102 respectively. The interiors of the front and rear fixed blocks 207 are slidably connected to the outer walls of the front and rear fixed rods 103 respectively. Push rods 208 are movably connected to the interiors of the plurality of through holes 206.

[0024] The motor 1 201 drives the connecting rod 1 202 to rotate, and the connecting rod 1 202 drives the connecting rods 2 203 on both sides to move, thereby driving the fixed column 204 to move inside the sliding hole 101, and the two fixed columns 204 drive the two movable plates 205 above to move toward each other.

[0025] A transmission box 209 is fixedly connected to the side of multiple push rods 208 away from the movable plate 205, and the lower surface of the transmission box 209 is movably connected to the upper surface of the detection platform 1. A spring 1 210 is sleeved on the surface of multiple push rods 208 located between the transmission box 209 and the movable plate 205. Square holes 211 are provided on the front and back sides of the side of the transmission box 209 away from the push rod 208. A support plate 218 is fixedly connected to the lower side of the transmission box 209 away from the push rod 208. The lower surface of the support plate 218 is movably connected to the upper surface of the detection platform 1. The front surface of the transmission box 209 is fixedly connected to a motor 212.

[0026] The front and rear sides of the surface of the bidirectional screw rod 213 are both threadedly connected with movable blocks 214, the outer walls of the left and right movable blocks 214 are movably connected to the inner wall of the transmission box 209, the outer walls of the left and right movable blocks 214 are movably connected to the inner wall of the square hole 211, the interior of the left and right movable blocks 214, located outside the transmission box 209, are movably connected with square rods 215, and the sides of the left and right square rods 215 close to each other are fixedly connected with clamping plates 216, the outer wall of the clamping plate 216 is movably connected to the upper surface of the support plate 218, and the surface of the square rod 215 is located between the clamping plate 216 and the movable block 214 and is sleeved with a spring 217.

[0027] When the movable plates 205 on both sides move toward each other, the push rods 208 push the transmission boxes 209 and the support plates 218 on both sides to move toward each other. When the distance between the transmission boxes 209 on both sides is roughly the same as the size of the circuit board, but larger than the size of the circuit board, the circuit board is placed on the support plates 218 on both sides, and then the transmission boxes 209 on both sides continue to move toward each other to fix the left and right sides of the circuit board. When the transmission boxes 209 contact the circuit board, the force generated is greater than the elastic force of the spring 1 210, and the push rods 208 will move, which can prevent the transmission boxes 209 from having a large clamping force on the circuit board, which may cause damage to the circuit board. After the left and right sides of the circuit board are fixed, the two-way screw rod 213 is driven by the motor 212 to rotate, so that the movable blocks 214 on the front and rear sides move toward each other. When the clamping plates 216 on both sides contact the circuit board, when the force between the clamping plates 216 and the circuit board is greater than the elastic force of the spring 217, the square rod 215 will move, preventing the large clamping force on the circuit board from causing damage to the circuit board, and also achieving the purpose of clamping and fixing circuit boards of different sizes.

[0028] like Figure 6 As shown, the angle adjustment assembly 3 includes two support legs 301 arranged in parallel on the left and right sides, a fixed plate 302 is fixedly connected to the upper right surface of the right support leg 301, a protective box 303 is arranged above the fixed plate 302, the left surface of the protective box 303 is fixedly connected to the right surface of the right support leg 301, and the rear side of the upper surface of the fixed plate 302 is fixedly connected to a motor three 304, the output end of the motor three 304 passes through the interior of the protective box 303 and is fixedly connected to a worm 305, the other end of the worm 305 is rotatably connected to the inner wall of the protective box 303, a worm gear 306 is meshed with the upper part of the worm 305, and a rotating rod 307 is fixedly connected to the middle part of the worm gear 306, the rotating rod 307 is fixedly connected to the outer wall and the left and right connecting frames 104, and the rotating rod 307 is rotatably connected to the left and right support legs 301.

[0029] After the circuit board is clamped and fixed, the operator can drive the worm 305 to rotate through the motor 3 304 according to the angle he wants, and then drive the worm wheel 306 and the rotating rod 307 to rotate, and drive the inspection table 1 to rotate through the rotating rod 307 and the connecting frame 104, thereby changing the inclination angle of the circuit board, making it convenient for the operator to detect the circuit board conveniently and quickly.

[0030] The working principle of the clamping device for circuit board detection is described in detail below.

[0031] like Figure 1-6As shown, when using the device, first, the motor 1 201 drives the connecting rod 1 202 to rotate, and the connecting rod 203 on both sides is driven to move by the connecting rod 1 202, thereby driving the fixed column 204 to move inside the sliding hole 101, and the two movable plates 205 above are driven to move toward each other through the two fixed columns 204. When the movable plates 205 on both sides move toward each other, the push rod 208 pushes the transmission boxes 209 and the support plates 218 on both sides to move toward each other. When the distance between the transmission boxes 209 on both sides is roughly the same as the size of the circuit board, it is larger than the size of the circuit board. The circuit board is placed above the support plates 218 on both sides, and then the transmission boxes 209 on both sides continue to move toward each other to fix the left and right sides of the circuit board. When the transmission box 209 contacts the circuit board, the force generated is greater than the elastic force of the spring 1 210, and the push rod 208 will move to prevent the transmission box 209 from moving. The clamping force on the circuit board is too large, which may cause damage to the circuit board. After the left and right sides of the circuit board are fixed, the two-way screw rod 213 is driven to rotate by motor 212, so that the movable blocks 214 on the front and rear sides move toward each other. When the clamping plates 216 on both sides contact the circuit board, when the force between the clamping plates 216 and the circuit board is greater than the elastic force of spring 217, the square rod 215 will move, preventing the circuit board from being damaged by the large clamping force, and also achieving the purpose of clamping and fixing circuit boards of different sizes. After the circuit board is clamped and fixed, the operator can drive the worm 305 to rotate through motor 304 according to the angle he wants, and then drive the worm gear 306 and the rotating rod 307 to rotate, and drive the detection table 1 to rotate through the rotating rod 307 and the connecting frame 104, thereby changing the inclination angle of the circuit board, making it convenient for the operator to detect the circuit board conveniently and quickly.

[0032] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
