Description

Technical Field

[0001] This application relates to the technical field of testing equipment, and in particular to a testing device for board-to-board connectors. Background Technology

[0002] Board-to-board connectors are electronic components designed to establish direct, pluggable electrical and mechanical connections between two or more printed circuit boards (PCBs). FPC board-to-board connectors are generally mounted on PCBs, and the pins on the board-to-board connectors need to be soldered to the PCBs. The pin accuracy requirements of board-to-board connectors are very high, and the testing equipment needs to use CCD vision inspection.

[0003] In related technologies, the testing equipment includes a moving mechanism, a placement seat, and a camera. The moving mechanism is used to place the board-to-board connector on the placement seat, and the camera takes pictures of the board-to-board connector for testing.

[0004] The distance between the pins of the board-to-board connector and the surface of the board-to-board connector that abuts against the PCB board needs to be within 10 microns. Since the CCD vision inspection equipment has an error of 2 microns, the camera may misjudge some board-to-board connectors that are qualified with 9-10 microns as unqualified board-to-board connectors with 11-12 microns, which will cause the inspection equipment to make a detection error. Summary of the Invention

[0005] To improve the situation where testing equipment may produce testing errors, this application provides a testing device for board-to-board connectors.

[0006] This application provides a testing device for board-to-board connectors, which adopts the following technical solution: A board-to-board connector testing device includes a placement base, a moving mechanism, and a testing mechanism. The moving mechanism is used to place the board-to-board connector on the placement base. The testing mechanism includes a first visual detection structure, a second visual detection structure, a reflector, and a reflective moving component. The first visual detection structure is used to directly detect the board-to-board connector. The reflective moving component is used to move the reflector between the first visual detection structure and the board-to-board connector. The reflector is used to reflect the board-to-board connector into the second visual detection structure.

[0007] By adopting the above technical solution, the operator first places the board-to-board connector on the placement seat using the moving mechanism. Then, the first visual inspection structure performs visual inspection on the board-to-board connector. Next, the reflective moving component drives the reflector to move, positioning the reflector between the first visual inspection structure and the board-to-board connector. This allows the board-to-board connector to be reflected by the reflector into the second visual inspection structure, which then performs visual inspection on the board-to-board connector. By detecting the board-to-board connector at the same angle using both the first and second visual inspection structures, the probability of misjudgment by both visual inspection structures is extremely low, greatly reducing the possibility of detection errors in the inspection equipment. Furthermore, the board-to-board connector, the first visual inspection structure, and the second visual inspection structure do not move, further reducing the errors caused by movement of the first and second visual inspection structures.

[0008] Optionally, the reflective moving assembly is provided with a mounting base, the reflector is rotatably connected to the mounting base, and multiple mounting strips are slidably connected to the mounting base, the mounting strips abutting against the reflector; when the mounting strips abut against the reflector, the reflector cannot rotate.

[0009] By adopting the above technical solution, the staff first rotates the reflector to adjust its angle, and then slides the mounting strip so that it can abut against the reflector, thereby restricting the rotation of the reflector and allowing it to be stably positioned on the mounting base.

[0010] Optionally, the mounting strip is provided with a mounting block, and the reflector is located between the mounting block and the mounting base.

[0011] By adopting the above technical solution, the reflector is positioned between the mounting block and the mounting base, which restricts the movement of the reflector, reduces the possibility of the reflector detaching from the mounting base, and further allows the reflector to be fixed on the mounting base.

[0012] Optionally, the mounting strip has multiple mounting holes distributed along the length of the mounting strip, and the mounting base has a stop strip for inserting into the mounting holes.

[0013] By adopting the above technical solution, the stop strip is inserted into different mounting holes to restrict the movement of the mounting strip, so that the mounting strip can stably limit the position of the reflector and reduce the possibility of the reflector shaking.

[0014] Optionally, the mounting base is provided with an airbag, which covers the mounting strip and the stop strip.

[0015] By adopting the above technical solution, the airbag covers the mounting strip and the stop strip, reducing their movement and enabling them to stably fix the reflector, further reducing the possibility of the reflector shaking.

[0016] Optionally, the mounting base is provided with a first positioning block, and the placement base is provided with a second positioning block; when the reflector plate is aligned with the board connector, the first visual detection structure is used to capture the first positioning block, and the first positioning block is completely fitted with the second positioning block.

[0017] By adopting the above technical solution, when the first vision detection structure takes a picture of the first positioning block, the first positioning block is completely attached to the second positioning block. At this time, the first vision detection structure cannot take a picture of the second positioning block, and the system can determine that the position of the reflector is correct, thereby reducing the error caused by the reflector moving component moving the reflector and allowing the reflector to be stably located in a fixed position.

[0018] Optionally, a first detection block is provided on the mirror surface of the reflector, and a second detection block is provided on the placement seat; when the reflector plate is connected to the plate connector, the second visual detection structure is used to capture the first detection block, and the first detection block is completely attached to the second detection block.

[0019] By adopting the above technical solution, the first detection block is placed in the second detection block through the second vision detection structure, and the first detection block is completely attached to the second detection block. The first detection block is set on the mirror surface of the reflector, so that the system can determine whether the deflection angle of the reflector has shifted. This allows the reflector to stably reflect the board-to-board connector to the second vision detection structure. If the reflector may shift when the reflector moving component moves the reflector, the second vision detection structure can capture the second detection block. At this time, the reflector will shift, and the staff can know that the reflector needs to be adjusted to determine the reflection angle of the reflector.

[0020] Optionally, the moving mechanism includes a suction cup and a moving structure. The suction cup is disposed on the moving structure, and the moving structure is used to drive the suction cup to move. The suction cup can adsorb board-to-board connectors.

[0021] By adopting the above technical solution, the board-to-board connector is adsorbed by a suction cup, which reduces the possibility of damage to the board-to-board connector shell caused by clamping the board-to-board connector. At the same time, the suction cup adsorption can place the board-to-board connector more stably, reducing the possible displacement of the board-to-board connector during placement.

[0022] In summary, this application includes at least one of the following beneficial technical effects: The operator first places the board-to-board connector on the placement seat using the moving mechanism. Then, the first visual inspection structure performs visual inspection on the board-to-board connector. Next, the reflective moving component moves the reflector, positioning it between the first visual inspection structure and the board-to-board connector. This allows the board-to-board connector to be reflected into the second visual inspection structure, which then performs visual inspection on it. By having the first and second visual inspection structures inspect at the same angle, the probability of both vision inspection structures making false judgments is extremely low, significantly reducing the possibility of inspection errors. Furthermore, the board-to-board connector, the first visual inspection structure, and the second visual inspection structure do not move, further reducing errors caused by movement of the first and second visual inspection structures.

[0023] The second vision detection structure uses a first detection block to completely fit the second detection block, and the first detection block is placed on the reflector. This allows the system to determine whether the deflection angle of the reflector has shifted, ensuring that the reflector can stably reflect the board-to-board connector to the second vision detection structure. If the reflector may shift when the reflector moving component moves, the second vision detection structure can capture the second detection block. At this time, the reflector will shift, and the staff can then know that the reflector needs to be adjusted to determine the reflection angle. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-3 This application will be described in further detail.

[0027] This embodiment discloses a testing device for board-to-board connectors. (Refer to...) Figure 1 A testing device for board-to-board connectors includes a placement base 1, a moving mechanism 2, and a testing mechanism 3. Four placement blocks 14 are fixedly connected to the placement base 1, and board-to-board connectors are placed between two placement blocks 14. Multiple light sources 11 are fixedly connected to the placement base 1, and the multiple light sources 11 are arranged in an array along the length direction of the placement base 1, wherein the light sources 11 are aligned with the board-to-board connectors in the placement blocks 14.

[0028] Reference Figure 1 A discharge structure 4 is fixedly connected to the placement base 1. The discharge structure 4 includes a discharge cylinder, and a discharge block 41 is fixedly connected to the drive shaft of the discharge cylinder. A drop hole is opened on the placement base 1, and the discharge block 41 blocks the drop hole. When the detection mechanism 3 detects that the board-to-board connector is defective, the discharge cylinder is activated. The discharge cylinder drives the discharge block 41 to not block the drop hole, and at this time the board-to-board connector can fall from the drop hole.

[0029] Reference Figure 1 The moving mechanism 2 includes multiple suction cups 21 and a moving structure 22. The moving structure 22 includes a lateral moving component 23 and multiple longitudinal moving components 24. The lateral moving component 23 includes a linear motor drive platform, and the longitudinal moving component 24 includes a drive cylinder. The drive cylinder is fixedly connected to the linear motor drive platform, and the suction cups 21 are fixedly connected to the drive cylinder. The linear motor drive platform can drive the drive cylinder to move along the length direction of the placement seat 1, and the drive cylinder drives the suction cups 21 to move closer to or away from the placement seat 1. In other embodiments, the lateral moving component 23 and the longitudinal moving component 24 may have other structures.

[0030] Reference Figure 1 The inspection mechanism 3 includes a first visual inspection structure 31, a second visual inspection structure 32, a reflector 33, and a reflective moving assembly 34. The first visual inspection structure 31 and the second visual inspection structure 32 are capable of inspecting board-to-board connectors. The reflective moving assembly 34 is used to move the reflector 33 vertically. The reflective moving assembly 34 is located between the placement base 1 and the first visual inspection structure 31. Both the first visual inspection structure 31 and the second visual inspection structure 32 are CCD visual inspection devices.

[0031] Reference Figure 1 and Figure 2 The reflective moving component 34 includes a linear motor drive platform, on which a mounting base 35 is fixedly connected. The mounting base 35 has a through hole 351 extending to the side of the mounting base 35 away from the first visual detection structure 31, i.e., the mounting base 35 is C-shaped.

[0032] Reference Figure 2The mounting base 35 has multiple sliding holes 352 that connect to the through hole 351, and multiple mounting strips 353 are slidably connected within each sliding hole 352. A mounting block 354 is fixedly connected to the surface of the mounting strip 353 away from the ground. The reflector 33 is rotatably connected to the through hole 351, and the mounting block 354 is located on the side of the reflector 33 away from the ground. The multiple mounting strips 353 are located at both ends of the reflector 33. When the reflector 33 rotates, it pushes the mounting strips 353 away from the reflector 33. Then, the operator pushes the mounting strips 353 in the opposite direction, causing them to abut against the reflector 33, thus fixing the reflector 33 to the mounting base 35. The rotation of the reflector 33 allows the board-to-board connectors at different positions to be reflected into the second vision inspection structure 32.

[0033] Reference Figure 2 The mounting strip 353 has multiple mounting holes 355 arranged in an array along its length. The mounting base 35 has a stop strip 356 that can be inserted into the mounting holes 355. When the reflector 33 is mounted on the mounting base 35, the mounting strip 353 protrudes from the mounting base 35. At this time, the operator inserts the stop strip 356 into the mounting holes 355 to fix the mounting strip 353 in place, reducing slippage of the mounting strip 353 on the mounting base 35.

[0034] Reference Figure 2 An airbag 357 is fixedly connected to both ends of the mounting base 35. After the airbag 357 is inflated, it can cover multiple mounting strips 353, reducing the sliding of the mounting strips 353 on the mounting base 35.

[0035] Reference Figure 1 and Figure 2 When the board-to-board connector is placed on the placement base 1, the light source 11 illuminates the board-to-board connector. The first vision detection structure 31 can directly photograph the pins of the board-to-board connector. Then, the reflective moving component 34 drives the mounting base 35 to fall. At this time, the reflector 33 is located between the board-to-board connector and the first vision detection structure 31, so that the reflector 33 can reflect the board-to-board connector to the second vision detection structure 32, so that the second vision detection structure 32 can photograph the board-to-board connector at the same angle, that is, the second vision detection structure 32 can photograph the reflected light of the board-to-board connector.

[0036] Reference Figure 2 and Figure 3Multiple second positioning blocks 12 are fixedly connected to the surface of the placement block 14 away from the ground, and the multiple second positioning blocks 12 are arranged in an array along the length direction of the placement seat 1. Multiple second detection blocks 13 are fixedly connected to the side of the placement seat 1 near the first visual detection structure 31, and the multiple second detection blocks 13 are arranged in an array along the length direction of the placement seat 1.

[0037] Reference Figure 2 and Figure 3 A first positioning block 36 is fixedly connected to the side of the reflector 33 away from the ground. The first positioning block 36 is identical to the second positioning block 12. When the reflector 33 is located between the first vision detection structure 31 and the board-to-board connector, the first vision detection structure 31 takes a picture of the reflector 33. At this time, the first positioning block 36 in the reflector 33 can completely block the second positioning block 12, that is, the first vision detection structure 31 cannot take a picture of the second positioning block 12, so that the operator can determine whether the reflector 33 has moved into place.

[0038] Reference Figure 2 and Figure 3 A first detection block 37 is fixedly connected to the surface of the reflector 33. The first detection block 37 is identical to the second detection block 13. When the reflector 33 is located between the first visual inspection structure 31 and the board-to-board connector, the second visual inspection structure takes a picture of the reflector 33. At this time, the first detection block 37 and the second detection block 13 in the reflector 33 are completely overlapped, that is, the second visual inspection structure 32 cannot take a picture of the second detection block 13, so that the staff can judge whether the reflection of the reflector 33 is incorrect.

[0039] The implementation principle of a board-to-board connector detection device according to an embodiment of this application is as follows: the operator moves the board-to-board connector to the placement seat 1 by moving mechanism 2, then the first vision detection structure 31 takes a picture of the board-to-board connector, and then the reflective moving component 34 moves the reflector 33 to the space between the first vision detection structure 31 and the board-to-board connector, so that the reflector 33 reflects the board-to-board connector to the second vision detection structure 32, and the second vision detection structure 32 takes a picture of the board-to-board connector at the same angle.
