[0028] It is understandable that, referring to Figures 1 to 4The circuit board detection device of the present invention includes a detection mechanism 100, a conveying mechanism 200 and a positioning mechanism 300. The detection mechanism 100 is provided with a detection platform 110, which is used to detect the circuit board; the conveying mechanism 200 includes a frame 210, a lifting platform 220 and a moving component 230. The lifting platform 220 is slidably connected to the frame 210, and the lifting platform 220 is used to support the circuit board. The lifting platform 220 can move up and down. The moving component 230 includes a suction cup 240, a first driving member 250 and a second driving member 260. The suction cup 240 is connected to the movable end of the first driving member 250. The first driving member 250 is used to drive the suction cup 240 to move up and down, and the second driving member 260 is used to drive the first driving member 250 to move in the horizontal direction so that The suction cup 240 transports the circuit board between the lifting platform 220 and the inspection platform 110; the positioning mechanism 300 includes two positioning plates 310 and two guide belts 320, and the two positioning plates 310 are fixedly connected to the frame 210 along the first direction and the second direction respectively. The first direction and the second direction are perpendicular to each other. The two guide belts 320 are both rotatable. The positioning plates 310 and the guide belts 320 are one-to-one corresponding to each other. The two guide belts 320 are both arranged in the vertical direction. The two guide belts 320 are respectively connected to the third driving member 321 and the fourth driving member 322. The third driving member 321 is used to drive the guide belt 320 to move in the first direction, and the fourth driving member 322 is used to drive the guide belt 320 to move in the second direction, so as to drive the circuit board to abut against the two positioning plates 310 respectively.

[0029] The lifting platform 220 is slidably connected to the frame 210, and multiple circuit boards are placed on the lifting platform 220. The lifting platform 220 drives the circuit boards to rise so that the circuit boards can approach the moving component 230. The two positioning plates 310 are fixedly connected to the frame 210 along the first direction and the second direction respectively. The positioning plates 310 and the guide belts 320 are in one-to-one correspondence. The third driving member 321 drives one of the guide belts 320 to move in the first direction, and the fourth driving member 322 drives the other guide belt 320 to move in the second direction, so that the two guide belts 320 cooperate to drive the circuit boards to abut against the two positioning plates 310, so that the circuit boards can be positioned on the lifting platform 220, thereby improving the position accuracy of the circuit boards, facilitating the connection of the circuit boards with the test pins on the test platform 110, and improving the stability of the detection.

[0030] The first driving member 250 drives the suction cup 240 to descend so that the suction cup 240 can absorb the circuit board. Then, the first driving member 250 drives the suction cup 240 to rise, and the second driving member 260 drives the first driving member 250 to move in the horizontal direction so that the circuit board can be transported from the lifting platform 220 to the testing platform 110, thereby realizing automatic loading of the circuit board and enabling the testing platform 110 to automatically test the circuit board. By setting two guide belts 320 arranged in a vertical direction and the two guide belts 320 being able to rotate, when the first driving member 250 drives the suction cup 240 to rise, the circuit board can abut against the guide belts 320, thereby guiding the movement of the circuit board through the guide belts 320, buffering and absorbing the position deviation of the circuit board, improving the conveying accuracy of the circuit board, and facilitating the testing of the circuit board.

[0031] It should be noted that when the first driving member 250 drives the suction cup 240 to rise, the suction cup 240 can drive the circuit board to rise, and the edge of the circuit board can abut against the guide belt 320, so that the circuit board can drive the guide belt 320 to move. The guide belt 320 can guide the movement of the circuit board, thereby reducing the friction between the edge of the circuit board and the positioning plate 310, preventing the position of the suction cup 240 and the circuit board from being offset, and improving the conveying accuracy of the circuit board.

[0032] The lifting platform 220 can be driven to move up and down by a linear cylinder, a linear oil cylinder, an electric push rod or a linear slide module, which will not be described in detail here.

[0033] In addition, a storage platform 410 is provided on one side of the lifting platform 220. The storage platform 410 can be raised and lowered within the rack 210. After the circuit board is removed from the inspection platform 110, the circuit board is stored in the storage platform 410 via the movable assembly 230, which facilitates the arrangement of the circuit boards. The number of storage platforms 410 can be set to two, one for storing qualified products and the other for storing unqualified products, thus avoiding confusion in the placement of circuit boards and improving ease of use.

[0034] It is understandable that, referring to Figure 1 and Figure 2The positioning mechanism 300 also includes an adjustment component 330, which includes an adjustment frame 331, a first slider 332 and a second slider 333. The adjustment frame 331 is fixedly connected to the lifting platform 220, and the first slider 332 and the second slider 333 can both be slidably connected to the adjustment frame 331 along the second direction. The third driving member 321 is fixedly connected to the first slide 334, and the fourth driving member 322 is fixedly connected to the second slide 335. The first slide 334 is slidably connected to the first slider 332 along the first direction, and the second slide 335 is slidably connected to the second slider 333 along the first direction. The adjusting frame 331 is fixedly connected to the lifting platform 220, and the first slider 332 and the second slider 333 are both slidably connected to the adjusting frame 331 so that the first slider 332 and the second slider 333 can both slide in the second direction, and the first slide plate 334 and the second slide plate 335 are slidably connected to the first slider 332 and the second slider 333 respectively so that the first slide plate 334 and the second slide plate 335 can slide in the first direction. Through the cooperation of the first slider 332 and the first slide plate 334, the position of the third driving member 321 can be conveniently adjusted, and through the cooperation of the second slider 333 and the second slide plate 335, the position of the fourth driving member 322 can be conveniently adjusted, so that the third driving member 321 and the fourth driving member 322 can conveniently drive the guide belt 320 to move, can adapt to the size of the circuit board, and facilitate the guide belt 320 to abut against the circuit board.

[0035] Among them, by driving the first slider 332 to move along the second direction and the first slide plate 334 to move along the first direction, the position flexibility of the third driving member 321 can be improved; by driving the second slider 333 to move along the second direction and the second slider 333 to move along the first direction, the flexibility of the fourth driving member 322 can be improved, so that the positions of the two guide belts 320 can be easily adjusted, so that the guide belts 320 can be easily abutted against the circuit board, thereby avoiding the skewness of the position of the circuit board and improving the positioning accuracy of the circuit board.

[0036] Specifically, refer to Figure 2 The first slider 332 and the second slider 333 are both threadedly connected with a first bolt 336, and the first bolt 336 can abut against the adjustment frame 331. The number of first bolts 336 is set to two, and the two first bolts 336 are respectively threadedly connected to the first slider 332 and the second slider 333. The first bolt 336 is driven to screw into the first slider 332 or the second slider 333 so that the first bolt 336 can abut against the adjustment frame 331, thereby locking the position of the first slider 332 or the second slider 333, facilitating the fixing of the position of the third driving member 321 or the fourth driving member 322, stabilizing the position of the two guide belts 320, and improving the reliability of the positioning mechanism 300.

[0037] Specifically, refer to Figure 2The first slide 334 and the second slide 335 are both provided with a slide groove 337 , and the slide groove 337 is penetrated by a second bolt 338 , and the second bolt 338 is threadedly connected to the first slider 332 or the second slider 333 . The first slide 334 and the second slide 335 are both provided with a sliding groove 337, and the number of second bolts 338 is two. The two second bolts 338 are respectively passed through the two sliding grooves 337, and the two second bolts 338 are respectively threadedly connected to the first slider 332 and the second slider 333, so that the first slide 334 can slide on the first slider 332 along the first direction, and the second slide 335 can slide on the second slider 333 along the first direction. By driving the second bolt 338 to screw into the first slider 332 or the second slider 333, the second bolt 338 can lock the first slide 334 on the first slider 332, and the second slide 335 can be locked on the second slider 333, so as to facilitate fixing the position of the third driving member 321 or the fourth driving member 322, so as to stabilize the position of the two guide belts 320 and improve the reliability of the positioning mechanism 300.

[0038] It is understandable that, referring to Figure 1 、 Figure 3 and Figure 4 The number of suction cups 240 is set to be multiple, and the moving assembly 230 also includes a connecting plate 270 and a plurality of adjustment plates 280. The connecting plate 270 is fixedly connected to the movable end of the first driving member 250. The connecting plate 270 is provided with a first adjustment groove 271. The adjustment plate 280 is penetrated by a third bolt 272. The third bolt 272 is slidably connected to the first adjustment groove 271. The third bolt 272 is threadedly connected to a nut 273. The nut 273 can abut the side of the connecting plate 270 away from the adjustment plate 280. The connecting plate 270 is fixedly connected to the movable end of the second driving member 260, and the connecting plate 270 can be driven to move up and down through the first driving member 250. The connecting plate 270 is provided with a first adjusting slot 271, and the third bolt 272 is passed through the adjusting plate 280, and the third bolt 272 is located in the first adjusting slot 271. The nut 273 is screwed into the third bolt 272, and the nut 273 is abutted against the side of the connecting plate 270 away from the adjusting plate 280, so that the position of the adjusting plate 280 on the connecting plate 270 can be easily adjusted, which makes it easier for the suction cup 240 to absorb the circuit board, adapt to the size of the circuit board, and improve applicability.

[0039] The suction cups 240 may correspond one to one with the adjustment plates 280 , or a plurality of suction cups 240 may be provided on one adjustment plate 280 , which is not limited here.

[0040] It should be noted that the number of the first adjustment slots 271 can be set to be multiple, so as to facilitate the arrangement of multiple adjustment plates 280 so that the suction cup 240 can easily absorb the circuit board.

[0041] Specifically, refer to Figure 3 and Figure 4 The adjustment plate 280 has a second adjustment slot 281, and the third bolt 272 is located in the second adjustment slot 281. The adjustment plate 280 has a second adjustment slot 281, and by arranging the third bolt 272 in the second adjustment slot 281, the adjustment plate 280 can move along the length of the second adjustment slot 281, thereby improving the position flexibility of the adjustment plate 280, facilitating the adjustment of the position of the suction cup 240, and improving the convenience of sucking the circuit board.

[0042] It is understandable that, referring to Figure 1 and Figure 4 The second driving member 260 includes a motor 261, a guide post 262, a screw 263, and a movable block 264. The guide post 262 is fixedly connected to the frame 210 in the horizontal direction, the movable block 264 is slidably connected to the guide post 262, and the screw 263 and the movable block 264 are threadedly connected. The first driving member 250 is fixedly connected to the movable block 264, and the motor 261 is used to drive the screw 263 to rotate. The guide post 262 is fixedly connected to the frame 210 in the horizontal direction, and the screw 263 is rotatably connected to the frame 210. By setting the movable block 264 to be slidably connected to the guide post 262, the slider can move along the axial direction of the guide post 262, and the screw 263 and the movable block 264 are threadedly connected. The motor 261 drives the screw 263 to rotate, so that the movable block 264 can move along the axial direction of the guide post 262, thereby driving the first driving member 250 to move in the horizontal direction, thereby improving the transportation efficiency of the circuit board.

[0043] It is understandable that, referring to Figure 1 The conveying mechanism 200 also includes a safety light barrier 290 and a controller. The safety light barrier 290 is disposed on either side of the lifting platform 220. Both the safety light barrier 290 and the lifting platform 220 are electrically connected to the controller. By disposing the safety light barriers 290 on either side of the lifting platform 220, the safety light barriers 290 can detect the presence of foreign objects on either side of the lifting platform 220. When the safety light barriers 290 detect a foreign object, the controller controls the lifting platform 220 to close, preventing the lifting platform 220 from colliding with foreign objects during the lifting process, thereby improving the safety and reliability of the circuit board inspection device.

[0044] It should be noted that the controller can be a single chip microcomputer, a programmable logic controller, an industrial computer, etc., which are not listed here one by one.
