DETAILED DESCRIPTION

[0019] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0020] See also Figures 1 to 12As shown in the figure, a detection device for integrated circuit board production includes a U-shaped plate 1, a connecting plate 2, a flipping mechanism 3, an adjustment and positioning mechanism 4, a detection mechanism 5, and a discharging mechanism 6. On both inner walls of the U-shaped plate 1, two rotating wheels 11 are rotatably arranged. The two rotating wheels 11 on the same side are传动连接 by a synchronous belt 12. A plurality of connecting plates 2 are equidistantly arranged between the two synchronous belts 12. The length direction of the connecting plate 2 is perpendicular to the conveying direction of the synchronous belt 12. A plurality of rectangular mounting grooves 21 are arranged on each connecting plate 2. A rectangular sleeve 22 is arranged in each rectangular mounting groove 21. A strip-shaped notch 221 is arranged at the center of each inner wall of the rectangular sleeve 22. A sliding block 23 is slidably arranged in each strip-shaped notch 221. At both ends of one side of each sliding block 23 close to the center of the corresponding rectangular sleeve 22 along the length direction, a hinge groove 231 is arranged. A limiting plate 24 is hinged in each hinge groove 231. There are multiple groups of flipping mechanisms 3. The flipping mechanism 3 is arranged on the corresponding sliding block 23. The flipping mechanism 3 can make the two limiting plates 24 perpendicular to each other and can make the corresponding two limiting plates 24 rotate synchronously along the hinge position with the movement of the synchronous belt 12. At both ends of the bottom inner wall of each strip-shaped notch 221 along the length direction, a rectangular through groove 222 is arranged. There are multiple groups of adjustment and positioning mechanisms 4. The adjustment and positioning mechanism 4 is arranged in the corresponding strip-shaped notch 221 and can fix the integrated circuit board with the movement of the sliding block 23. Each group of adjustment and positioning mechanisms 4 includes a moving strip 41 slidably arranged in the corresponding rectangular through groove 222. The two moving strips 41 can move synchronously and in opposite directions with the movement of the corresponding sliding block 23. One end of each moving strip 41 extending into the corresponding rectangular sleeve 22 is provided with a U-shaped abutting plate 42. A strip-shaped avoidance groove 241 for the moving strip 41 is arranged at the center of each limiting plate 24. A U-shaped mounting plate 13 is arranged on the top of the U-shaped plate 1. The detection mechanism 5 is arranged on the U-shaped mounting plate and is used to detect both sides of the integrated circuit board. The detection mechanism 5 includes a horizontal plate 51 that can move back and forth in the vertical direction. On one side of the horizontal plate 51 close to the bottom inner wall of the U-shaped plate 1 along the length direction, a plurality of square covers 52 corresponding to the rectangular sleeves 22 are arranged. A plurality of cameras 521 are arranged in a matrix distribution inside each square cover 52. The discharging mechanism 6 is arranged inside the U-shaped plate 1 and can classify and convey the integrated circuit boards according to the detection results.

[0021] With the synchronous movement of the two synchronous belts 12, the connecting plate 2 can move along the trajectory of the synchronous belt 12, and the trajectory of the synchronous belt 12 is in an elliptical shape; when the connecting plate 2 is located above the synchronous belt 12, under the action of the flipping mechanism 3, the two limiting plates 24 on the corresponding sliding blocks 23 are perpendicular to each other and in an L shape. Subsequently, multiple integrated circuit boards are placed inside the corresponding rectangular sleeves 22 through an external feeding mechanism (not shown in the figure). At this time, the limiting plates 24 at the lower ends of the multiple sliding blocks 23 are arranged horizontally and can form a "first horizontal plane" for placing the integrated circuit boards. The integrated circuit boards are in contact with the limiting plates 24 at the lower ends of the corresponding sliding blocks 23, so as to ensure that the integrated circuit boards can be completely exposed under the camera 521, so that the camera 521 can completely photograph the integrated circuit boards and ensure the detection accuracy; under the action of the gravity of the integrated circuit boards, the sliding blocks 23 can move towards the inner wall of the bottom of the C-shaped plate 1. During this process, the two moving strips 41 in the corresponding strip-shaped slots 221 can move synchronously and reversely with the movement of the corresponding sliding blocks 23. A strip-shaped avoidance slot 241 for the moving strip 41 is provided at the center of each limiting plate 24, so as to avoid volume collision between the limiting plate 24 and the moving strip 41; the two U-shaped abutting plates 42 in the same strip-shaped slot 221 are arranged alternately, so as to avoid volume collision of the U-shaped abutting plates 42 during the movement of the moving strip 41; with the synchronous reverse movement of the two moving strips 41, the multiple U-shaped abutting plates 42 facing the center of the corresponding rectangular sleeve 22 can contact the integrated circuit boards, while fixing the integrated circuit boards, it can also adjust the position of the integrated circuit boards to avoid shaking of the integrated circuit boards during the detection process and ensure the shooting accuracy of the camera 521; subsequently, by adjusting the horizontal plate 51, the horizontal plate 51 moves towards the inner wall of the bottom of the C-shaped plate 1, so that the square cover 52 can contact the corresponding rectangular sleeve 22. The multiple cameras 521 arranged inside the square cover 52 can photograph and detect one side of the multiple integrated circuit boards, so as to comprehensively detect the integrated circuit boards and avoid omission;As the synchronous belt 12 continues to rotate, when the connecting plate 2 moves to the bottom of the synchronous belt 12, the integrated circuit board automatically flips over with the movement of the synchronous belt 12. Subsequently, the flipping mechanism 3 can make the two limit plates 24 on the corresponding sliding block 23 rotate along the hinged position, so that the limit plates 24 at the upper ends of the plurality of sliding blocks 23 are arranged in a horizontal state and can form a "second horizontal plane" for placing the integrated circuit board. The integrated circuit board contacts the "second horizontal plane". At this time, under the action of the gravity of the integrated circuit board, the two moving strips 41 in the same strip-shaped notch 221 move in opposite directions. After the circuit board is loosened, the integrated circuit board is clamped again to adjust the position of the integrated circuit board for the second time. Then, the horizontal plate 51 moves toward the inner wall of the bottom of the shaped plate 1 through the gap between the two connecting plates 2. The multiple cameras 521 arranged inside the square cover 52 can shoot and detect the other side of the multiple integrated circuit boards, thereby simplifying the detection steps. Then, the multiple integrated circuit boards on the same connecting plate 2 are classified and transported according to the detection results of the two sides through the discharge mechanism 6, so that the integrated circuit boards can be continuously detected and the detection efficiency is improved. ;

[0022] It is particularly noted that the upper limiting plate 24 is the limiting plate 24 far away from the center of the elliptical track, and the lower limiting plate 24 is the limiting plate 24 close to the center of the elliptical track.

[0023] See also Figures 8 to 12 As shown, each set of flipping mechanisms 3 includes a first rack 31 and a return spring 32; a guide groove 232 penetrating the sliding block 23 is provided at one end of each sliding block 23 along the length direction, the guide groove 232 is connected with the corresponding two hinge grooves 231, the first rack 31 is slidably arranged in the corresponding guide groove 232, a synchronous gear 242 cooperating with the first rack 31 is provided in each bar-shaped avoidance groove 241, and the first rack 31 is meshed with the corresponding two driving gears; a circular groove 233 is provided at one end of each sliding block 23 along the length direction, the circular groove 233 is connected with the corresponding guide groove 232, a counterweight column 311 corresponding to the circular groove 233 is provided at the center of the first rack 31, the return spring 32 is arranged in the corresponding circular groove 233, and the two ends of the return spring 32 are respectively connected to the inner wall of the bottom of the circular groove 233 and the counterweight column 311.

[0024] The opening direction of the circular groove 233 faces away from the synchronous belt 12. When the rectangular sleeve 22 moves above the synchronous belt 12, under the action of gravity, the counterweight column 311 provided on the first rack 31 can move the first rack 31 towards the inner wall of the bottom of the C-shaped plate 1 while squeezing the return spring 32. During this process, through the transmission of the two driving gears, the two limiting plates 24 remain perpendicular to each other during the entire movement process, so that the lower limiting plate 24 can be set in a horizontal state, and the upper limiting plate 24 is set in a vertical state, so that the lower limiting plate 24 can support the integrated circuit board placed by the feeding mechanism (not shown in the figure), thereby preventing it from falling out of the rectangular sleeve 22; and by providing a return spring 32, when the connecting plate 2 carrying the integrated circuit board is set vertically with the synchronous belt 12, at this time, the gravity of the counterweight column 311 is in a "disappeared state", and under the elastic force of the return spring 32, the positions of the two limiting plates 24 can be adjusted, so that the upper limiting plate 24 can move towards the center of the synchronous belt 12 to prevent the integrated circuit board from falling when the connecting plate 2 moves to the end of the synchronous belt 12.

[0025] See Figures 8 to 12 As shown, each set of adjustment and positioning mechanisms 4 further includes a reciprocating gear 43 and a synchronous spring 44; on one side of each rectangular through groove 222 close to the center of the corresponding strip through groove, a communication groove 223 is provided. There are two reciprocating gears 43, and the reciprocating gears 43 are rotatably arranged in the corresponding communication grooves 223. Each moving strip 41 is provided with a plurality of tooth grooves 411 along the length direction, and the reciprocating gears 43 are engaged with the tooth grooves 411 of the corresponding moving strip 41; at both ends of each sliding block 23 along the length direction, two second racks 234 are provided, and the two second racks 234 are located on both sides of the corresponding moving strip 41, and the second racks 234 are respectively engaged with the corresponding reciprocating gears 43; at one end of each moving strip 41 away from the U-shaped contact plate 42, a limiting disc 412 is provided. There are two synchronous springs 44, and the synchronous springs 44 are sleeved on the corresponding moving strips 41 and are located between the corresponding limiting discs 412 and the outer wall of the rectangular sleeve 22.

[0026] By providing a synchronization spring 44, when the integrated circuit board is not placed on the limit plate 24, the positions of the two moving bars 41 can be adjusted, thereby preventing the moving bar 41 and the U-shaped contact plate 42 from affecting the placement of the integrated circuit board; the setting of the limit plate 412 can prevent the synchronization spring 44 from separating from the corresponding moving bar 41; when the integrated circuit board contacts the limit plate 24, under the action of gravity, the sliding block 23 moves, and the second rack 234 provided on the sliding block 23 meshes with the corresponding reciprocating gear 43, thereby driving the two moving bars 41 to move synchronously in opposite directions The U-shaped contact plate 42 moves toward the integrated circuit board, thereby being able to adjust the integrated circuit board and fix the integrated circuit board, thereby ensuring stability during the detection process; and when the connecting plate 2 moves to the end of the synchronous belt 12 (and when the connecting plate 2 is set in a vertical state), the sliding block 23 can be reset under the elastic force of the synchronous spring 44, thereby releasing the clamping of the integrated circuit board, thereby facilitating the flipping of the integrated circuit board. After flipping, the position of the integrated circuit board is re-adjusted and fixed, thereby improving the detection accuracy.

[0027] See also Fig. 9 As shown, an elastic telescopic rod 413 is further provided between each moving bar 41 and the U-shaped abutment plate 42 .

[0028] By providing the elastic telescopic rod 413 , the rigid collision between the U-shaped abutment plate 42 and the integrated circuit board can be further avoided, thereby avoiding damage to the integrated circuit board and protecting the integrated circuit board.

[0029] See also Fig.10 As shown, each inner wall of the rectangular sleeve 22 is also provided with a rectangular annular groove 224 for accommodating the U-shaped abutment plate 42 .

And the square cover 52 can cooperate with the corresponding rectangular sleeve 22, so as to further reduce the influence of external light on the shooting process.

[0036] Adjust the second hydraulic rod 623 so that the suction cups 625 on the negative pressure plate 624 can contact the integrated circuit board after the detection, thereby sucking up the integrated circuit board. Subsequently, according to the detection result of the detection mechanism 5, adjust the third hydraulic rod 63 at the corresponding position to place the qualified and unqualified integrated circuit boards on different conveyor belts 61 respectively, so as to realize the classified conveying of the integrated circuit boards, simplify the screening steps of the staff, and facilitate the staff to process the unqualified products.
