Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0038] As Figures 1 to 4 shown, the present utility model provides a visual inspection and electrical measurement device 10, which includes a device base 100, a positioning component 200 disposed on the device base 100, and a detection component 300 disposed on the device base 100. The detection component 300 is arranged corresponding to the positioning component 200 up and down. The positioning component 200 is used to position the circuit board to be detected, and the detection component 300 is used to perform appearance inspection and electrical performance inspection on the circuit board positioned by the positioning component 200.

[0039] Specifically, the positioning component 200 may include a positioning base 210 provided on the device base 100, a positioning block structure 220 detachably provided on the positioning base 210 for positioning the circuit board to be detected, and a limiting block structure 230 movably provided on the positioning base 210 and located outside the positioning block structure 220. The detection component 300 may include a detection frame structure 310 slidably provided on the device base 100, a detection frame driving structure 320 provided on the device base 100, an appearance vision detection mechanism 330 provided on the detection frame structure 310, and an electrical probe mechanism 340 liftably provided on the detection frame structure 310.

[0040] By providing a detachable positioning block structure 220 on the device base 100, different positioning block structures 220 can be adopted according to the type of the circuit board to be detected, and the limitation of the positioning block structure 220 can be adjusted by the adjustable limiting block structure 230, so as to adapt to different types of circuit boards. Moreover, by slidably arranging the detection frame structure 310 on the device base 100 and sequentially arranging the appearance vision detection mechanism 330 and the electrical probe mechanism 340 on the detection frame structure 310 above the device base 100, the appearance vision detection mechanism 330 and the electrical probe mechanism 340 can slide past the positioning block structure 220 and the circuit board positioned thereon successively; when the appearance vision detection mechanism 330 passes above the positioning block structure 220, the appearance of the circuit board positioned thereon can be detected; when the electrical probe mechanism 340 passes above the positioning block structure 220, the electrical probe mechanism 340 can be lowered and electrically connected to the circuit board positioned on the positioning block structure 220, so that the circuit board is electrically connected to the electrical measurement instrument through the electrical probe mechanism 340 to perform electrical performance detection on the circuit board.

[0041] Through the vision detection and electrical measurement device 10 provided by the present utility model, by slidably arranging the appearance vision detection mechanism 330 and the electrical probe mechanism 340 on the device base 100, the appearance of the circuit board can be detected simultaneously during the process of performing electrical performance testing on the circuit board, without separately arranging electrical measurement equipment and appearance detection equipment to detect the circuit board respectively, which can simplify the detection process flow and improve the detection efficiency; moreover, by providing a detachable positioning block structure 220 on the device base 100, different positioning block structures 220 can be replaced according to different types of circuit boards, and the limiting block structure 230 can be adjusted to limit the positioning block structure 220, so as to adapt to the detection of different types of circuit boards.

[0042] Further, the device base 100 may include a base plate 110 and side base plates 120 provided on both sides of the base plate 110. By respectively providing the side base plates 120 on both sides of the base plate 110, the device base 100 can form an inverted U-shaped plate structure; moreover, by slidably arranging the detection frame structure 310 on the side base plates 120 and arranging the positioning assembly 200 on the base plate 110, the occupied space of the entire device can be reduced. In addition, the device base 100 may also only include the base plate 110, slidably arrange the detection frame structure 310 on both sides of the base plate 110, arrange the positioning assembly 200 at the middle position of the base plate 110, and make the positioning assembly 200 located below the detection frame structure 310.

[0043] Moreover, the detection frame structure 310 may include one detection side plate 314 respectively slidably arranged on both sides of the device base 100, and a detection top plate 312 connected between the tops of the two detection side plates 314. The detection frame driving structure 320 is connected to the detection side plate 314, and the appearance visual detection mechanism 330 and the electrical probe mechanism 340 are respectively arranged on the front side and the rear side of the detection top plate 312. Moreover, the detection frame driving structure 320 may include a motor linear driving member 322 arranged on the base plate 110 or one of the side base plates 120 of the device base 100. One detection side plate 314 is slidably arranged on one side base plate 120 and connected to the motor linear driving member 322, and the other detection side plate 314 is slidably arranged on the other side base plate 120.

[0044] The motor linear driving member 322 can drive the detection frame structure 310 to reciprocate linearly along the length direction of the device base 100 (which can be regarded as the front-back direction of the device base 100), so that the appearance visual detection mechanism 330 and the electrical probe mechanism 340 on the detection frame structure 310 respectively move to directly above the positioning block structure 220 on the base plate 110. Thus, the appearance of the circuit board positioned on the positioning block structure 220 can be detected by the appearance visual detection mechanism 330, and the electrical performance of the circuit board positioned on the positioning block structure 220 can be detected by the electrical probe mechanism 340. In addition, by respectively slidably arranging the two detection side plates 314 of the detection frame structure 310 on the two side base plates 120 of the device base 100, the detection frame structure 310 can slide stably back and forth along the device base 100, and the occupied space of the detection frame structure 310 and the devices thereon can be reduced.

[0045] In this embodiment, the motor linear driving member 322 may include a linear motor driving module extending along the length direction of one side seat plate 120, and a detection side plate 314 is connected to the linear motor driving module. The motor linear driving member 322 can be set as a linear motor, or can be set as a linear motor driving module composed of a driving motor and a screw-nut transmission structure, and the detection frame structure 310 is linearly driven to reciprocate linearly along the length direction of the device base 100. When the motor linear driving member 322 is set as a linear motor, the stator of the linear motor can be arranged along the length direction of the side seat plate 120, and the detection side plate 314 can be connected to the mover of the linear motor, which can drive the detection side plate 314 to linearly move along the side seat plate 120; when the motor linear driving member 322 is a linear motor driving module composed of a driving motor and a screw-nut transmission structure, the driving motor of the linear motor driving module can be arranged on the base plate 110 or the side seat plate 120, the driving screw of the screw-nut transmission structure can be arranged along the length direction of the side seat plate 120, the transmission nut of the screw-nut transmission structure is threadedly connected to the driving screw, and the transmission nut is connected to a detection side plate 314.

[0046] Moreover, an auxiliary sliding guide rail and an auxiliary sliding slot are provided between the side surface of the other detection side plate 314 and the side surface of the other side seat plate 120, and the auxiliary sliding guide rail is slidably clamped in the auxiliary sliding slot. By providing the mutually matching auxiliary sliding guide rail and auxiliary sliding slot between the detection side plate 314 and the side seat plate 120, not only can the detection frame structure 310 be supported, but also the sliding of the detection frame structure 310 can be stable and reliable. In addition, not only can the mutually matching auxiliary sliding guide rail and auxiliary sliding slot be provided between one detection side plate 314 and the corresponding one side seat plate 120, but also the mutually matching auxiliary sliding guide rail and auxiliary sliding slot can be provided between the detection side plate 314 on the other side and the corresponding other side seat plate 120, so that the support and guidance of the detection frame structure 310 are more stable. Moreover, a pair of the auxiliary sliding guide rail and the auxiliary sliding slot can be provided between the linear motor driving module on one side seat plate 120 and the corresponding detection side plate 314.

[0047] In addition, as Figures 3 to 5As shown, the positioning block structure 220 of the positioning component 200 may include a main positioning block 222 provided on the positioning base 210, and a positioning cover plate 224 rotatably provided on the side of the main positioning block 222. Moreover, a circuit board positioning groove 2222 for positioning the circuit board to be detected is provided in the middle of the main positioning block 222, and detection positioning holes and / or detection positioning grooves are provided on the peripheral side of the main positioning block 222. The main positioning block 222 of the positioning block structure 220 can be detachably connected to the positioning base 210, so that different positioning block structures can be replaced according to the type of the circuit board to be detected; through the circuit board positioning groove 2222 provided on the main positioning block 222, the circuit board to be detected can be positioned, and through the positioning cover plate 224 rotatably connected to the main positioning block 222, the circuit board in the circuit board positioning groove 2222 can be further positioned from the top by rotating the positioning cover plate 224.

[0048] After the circuit board to be detected is placed in the circuit board positioning groove 2222 of the main positioning block 222, the detection frame structure 310 can be driven by the motor linear driving member 322 to move towards the position where the positioning block structure 220 is located. When the appearance vision detection mechanism 330 on the detection frame structure 310 moves directly above the positioning block structure 220, the appearance of the circuit board positioned in the circuit board positioning groove 2222 of the main positioning block 222 of the positioning block structure 220 can be detected by the appearance vision detection mechanism 330; then, the detection frame structure 310 can be driven by the motor linear driving member 322 to continue moving, so that the appearance vision detection mechanism 330 on the detection frame structure 310 moves to the front side of the positioning block structure 220, and the electrical probe mechanism 340 on the detection frame structure 310 moves directly above the circuit board positioned on the main positioning block 222; at this time, the circuit board positioned on the main positioning block 222 can be covered and positioned by the positioning cover plate 224, and the electrical probe mechanism 340 is lowered to cooperate with the detection positioning holes and / or detection positioning grooves provided on the peripheral side of the main positioning block 222, so that the electrical probe mechanism 340 is in electrical contact with the circuit board positioned on the main positioning block 222, so that the circuit board is electrically connected to the electrical measurement instrument through the electrical probe mechanism 340, thereby performing electrical performance detection on the circuit board.

[0049] Moreover, a plurality of limiting block structures 230 of the positioning component 200 may be provided, and the plurality of limiting block structures 230 surround the peripheral side of the positioning block structure 220. Through the plurality of limiting block structures 230, the main positioning block 222 and the circuit board positioned thereon can be limited from the peripheral side of the main positioning block 222 of the positioning block structure 220, so that the positioning of the circuit board by the positioning block structure 220 is more accurate.

[0050] Specifically, each limit block structure 230 may include a limit driving structure 232 disposed on the positioning base 210, and a limit block body 234 connected to the limit driving structure 232. The limit block body 234 is limited to the outside of the positioning block structure 220. The limit block body 234 can be driven to move through the limit driving structure 232, and the planar position and / or height position of the limit block body 234 on the positioning base 210 can be adjusted to correspondingly limit different positioning block structures 220 from different positions.

[0051] Moreover, the limit driving structure 232 may include a lateral cylinder driving member 2322 disposed on the positioning base 210, a lifting cylinder driving member 2324 disposed on the lateral cylinder driving member 2322, and a longitudinal cylinder driving member 2326 disposed on the lifting cylinder driving member 2324. The limit block body 234 is disposed on the longitudinal cylinder driving member 2326. Through the lateral cylinder driving member 2322, the horizontal lateral position of the limit block body 234 can be adjusted; through the longitudinal cylinder driving member 2326, the horizontal longitudinal position of the limit block body 234 can be adjusted; through the lifting cylinder driving member 2324, the height position of the limit block body 234 can be adjusted. In addition, the lifting cylinder driving member 2324 may also be disposed on the longitudinal cylinder driving member 2326, the longitudinal cylinder driving member 2326 is connected to the lateral cylinder driving member 2322, and the lifting cylinder driving member 2324 is connected to the limit block body 234.

[0052] In addition, as Figure 3 , Figure 4 , and Figure 6 shown, the appearance vision detection mechanism 330 may include a camera mounting bracket 332 disposed on the front side of the detection top plate 312 of the detection frame structure 310 (referring to the side of the detection frame structure 310 close to the positioning block structure 220), and a plurality of detection camera modules 334 disposed on the camera mounting bracket 332 and protruding outside the detection top plate 312. The plurality of detection camera modules 334 are all located above the positioning block structure 220. The appearance vision detection mechanism 330 disposed on the front side of the detection top plate 312 of the detection frame structure 310 can move along with the detection frame structure 310 on the device base 100. When the front side of the detection frame structure 310 moves to directly above the positioning block structure 220, the appearance of the circuit board positioned by the positioning block structure 220 can be detected from multiple positions through the plurality of detection camera modules 334 disposed on the camera mounting bracket 332. By providing a plurality of detection camera modules 334, multiple parts of the circuit board can be detected simultaneously, which is fast and efficient.

[0053] Moreover, the front side of the detection top plate 312 may have a detection notch, and multiple detection camera modules 334 are all located at the detection notch, so that the multiple detection camera modules 334 can pass through the detection notch on the detection top plate 312 and correspond to the positioning block structure 220 below and the circuit board positioned thereby up and down. Moreover, by providing detection notches corresponding to the multiple detection camera modules 334 on the detection top plate 312, the space occupied by the device can be reduced. Moreover, the multiple detection camera modules 334 can be arranged in two rows, and the two rows of detection camera modules 334 are respectively arranged on both sides of the camera mounting frame 332 in one-to-one correspondence. By arranging the multiple detection camera modules 334 in two rows, both sides of the circuit board can be detected respectively, and the detection speed can be further improved.

[0054] In addition, as Figure 3 , Figure 4 , and Figures 7 to 9 shown, the electrical probe mechanism 340 may include an electrical probe lifting structure 342 provided at the rear side of the detection top plate 312 (referring to the side of the detection frame structure 310 away from the positioning block structure 220), an electrical probe mounting frame 344 connected to the electrical probe lifting structure 342, and an electrical probe connector 346 and an electrical probe positioning protrusion 348 provided at the bottom of the electrical probe mounting frame 344. The electrical probe connector 346 is used for electrically connecting the circuit board to be detected and the electrical measuring instrument, and the electrical probe positioning protrusion 348 is used for positioning and cooperating with the positioning block structure 220. During the process that the detection frame structure 310 moves past the positioning block structure 220, the appearance vision detection mechanism 330 first moves to directly above the positioning block structure 220 along with the detection frame structure 310 to detect the appearance of the circuit board positioned by the positioning block structure 220, and then the electrical probe mechanism 340 moves to directly above the positioning block structure 220 along with the detection frame structure 310. At this time, the electrical probe lifting structure 342 of the electrical probe mechanism 340 is used to lift and move the electrical probe connector 346 and the electrical probe positioning protrusion 348 provided on the electrical probe mounting frame 344, so that the electrical probe positioning protrusion 348 cooperates with the detection positioning hole and / or detection positioning groove of the positioning block structure 220 to realize the positioning of the electrical probe mechanism 340 and the positioning block structure 220. At the same time, the electrical probe connector 346 is electrically connected to the connection terminal of the circuit board positioned by the positioning block structure 220, so that the circuit board is electrically connected to the electrical measuring instrument through the electrical probe connector 346.

The electrical measurement head lifting structure 342 is disposed on the lifting connection plate 3442. Multiple electrical measurement connectors 346 and multiple electrical measurement positioning protrusions 348 are provided at the bottom of the electrical measurement mounting plate 3448. The electrical measurement head mechanism 340 can be set as a whole through the electrical measurement head mounting bracket 344, which is convenient for installation, disassembly and maintenance. The electrical measurement head lifting structure 342 can drive the electrical measurement positioning plate 3446 to move up and down, so as to drive the multiple electrical measurement connectors 346 and the multiple electrical measurement positioning protrusions 348 provided at the bottom of the electrical measurement mounting plate 3448 to move up and down together, facilitating the mating and alignment connection between the multiple electrical measurement positioning protrusions 348 and the multiple detection positioning holes and multiple detection positioning grooves on the positioning block structure 220, and facilitating the electrical connection between the multiple electrical measurement connectors 346 and the multiple connection terminals of the circuit board positioned by the positioning block structure 220. The guiding connection frame 3444 conducts guiding and limiting during the up and down movement of the electrical measurement positioning plate 3446.

[0056] Furthermore, the electrical measurement positioning plate 3446 may include an electrical measurement positioning main board connected to the electrical measurement head lifting structure 342 and the guiding connection frame 3444, and an electrical measurement positioning bracket protruding from the bottom of the electrical measurement positioning main board.
