Description

Technical Field

[0001] The present invention belongs to the technical field of automated detection equipment, and in particular relates to a 3D detection device and method for connectors. Background Art

[0002] One type of 3D inspection equipment used for connectors is a 3D visual inspection system, which can accurately present the geometric shape of connector pins in a non-contact manner, detect important information such as the height and position of the pins, detect connector defects in a timely manner, and effectively eliminate unqualified products.

[0003] In the prior art, the device is aimed at the connector to be inspected, and the surface of the connector is illuminated by a light-assisted system. The 3D camera module is then started to perform an all-round scan of the connector to obtain its 3D shape and size data. Finally, the inspection data is processed by the built-in analysis software of the device to evaluate the quality of the connector or detect whether there are any defects.

[0004] There are still some problems in the actual application of the above scheme. Although the existing device can complete the detection of connectors, when detecting dark-colored connectors, due to the dark surface color of dark-colored connectors, the light absorption capacity is strong, which will cause most of the light to be absorbed when projected onto the dark surface, and only a small part can be reflected back to the scanner's sensor. Therefore, when the reflected light signal received by the scanner is weak, the device cannot accurately capture all the details of the connector, resulting in a decrease in detection accuracy. At the same time, in order to make up for the lack of information caused by the weak reflected light signal, the 3D detection equipment requires a longer exposure time or multiple scans of the same area to collect sufficient data, which will slow down the detection speed and reduce production efficiency. Secondly, when some pins in the connector are gathered in the corner, the light cannot evenly illuminate every corner and every pin, which will cause some pins to be in the shadow and difficult to be accurately captured by the detection equipment.

[0005] To this end, the present invention provides a 3D detection device and method for a connector. Summary of the invention

[0016] A 3D detection method for a connector, specifically:

[0017] Equipment preparation and debugging: Conduct a comprehensive inspection of the testing equipment before use, and install the corresponding testing software according to the equipment requirements;

[0018] Sample preparation and placement: Select the corresponding connector according to the test requirements, clean the connector, and place the connector on the positioning clamp after cleaning;

[0019] Operation implementation: Start the measurement program and start the light source to fill the connector with light. When encountering a dark connector, the two sets of external motors are driven to move towards each other through the rotation of the bidirectional screw rod, and the two sets of light-transmitting mirrors are squeezed to make the two sets of light-transmitting mirrors present a convex lens-like state, so as to focus the light inside the dark connector being tested;

[0020] Data Analysis: When the inspection is completed, the collected data will be processed and analyzed to evaluate the quality and performance of the connector and generate an analysis report for subsequent use.

[0021] The operation is implemented specifically as follows: first, the connector is placed on the upper part of the positioning clamp for fixing, and then the detection camera and the electric telescopic rod are started. At this time, the light will shine on the connector through the two sets of uncompressed light-transmitting mirrors, and the external motor is started at the same time. At this time, the two sets of moving blocks connected to the external motor will move toward the middle of the two-way screw rod at the same time, and then drive the sliding baffle to move synchronously. During the movement, since the two sets of light-transmitting mirrors are made of flexible materials and are resisted by the guide blocks, they will protrude outward synchronously, thereby forming the effect of a double-sided convex lens, so that the interior of the dark connector can be focused.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. The present invention starts an external motor, and when the bidirectional screw rotates, it will drive the two groups of moving blocks to move synchronously. Since the first guide blocks are fixed on the sides of the two groups of moving blocks, and the first guide blocks slide inside the first limiting groove, the moving blocks limited by the first limiting groove will perform relative linear motion when the bidirectional screw rotates, and will squeeze the two groups of light-transmitting mirrors while moving. Due to the guide blocks arranged in the middle of the two groups of light-transmitting mirrors, it can avoid the situation that the two groups of light-transmitting mirrors bend inward when they are squeezed, so that the light emitted by the light source can be focused inside the dark connector. When the moving block moves, it will drive the sliding baffle fixed with it to move synchronously. During the movement, the sliding baffle will gradually unfold, so as to avoid the situation that the light is emitted outward when the two groups of light-transmitting mirrors are squeezed. At this time, the light can be gathered by bending the middle parts of the two groups of light-transmitting mirrors towards each other, so that more light can be guided to the inside of the connector, thereby improving the detection accuracy, which enables the detection personnel to more accurately judge the structure and material of the connector and whether there are defects.

[0024] 2. The present invention starts the electric telescopic rod and drives the light source fixed thereto to move along the guide of the limit frame through the electric telescopic rod, so as to adjust the position of the light source and then the position where the light is focused, so that the light is focused on the pin area, which can enhance the lighting intensity of the area, thereby improving the visibility and recognition of the pin. At the same time, when the detection is completed, the light source will return to the initial state driven by the electric telescopic rod. At this time, the electric telescopic rod will drive the light source to continue to move downward along the direction of the limit frame. When the bottom of the light source contacts the upper part of the trigger adjustment block, it will squeeze the trigger adjustment block to move along the guide of the third limit groove. When the trigger adjustment block moves, it will drive the conveyor belt to transmit, and drive the cleaning plate on the other side to move upward during the transmission. When the trigger adjustment block and the cleaning plate are on the same horizontal plane, the cleaning plate is tightly fitted with the light source lampshade. At this time, the electric telescopic rod will continue to move downward, and the synchronous cleaning plate will continue to move upward, so that the light source lampshade can be wiped, thereby improving the effect of the next detection.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0040] Embodiment 1

[0041] like Figures 1 to 9 As shown, one embodiment of the present invention is:

[0042] A 3D detection device for a connector, comprising a detection device 1, wherein the detection device 1 comprises a protective shell 101, a positioning clamp 102 is fixedly arranged on the side of the protective shell 101, a connector 103 is arranged on the upper part of the positioning clamp 102, an inner cavity is opened inside the protective shell 101, an electric guide rail 104 is fixedly connected to the bottom of the inner cavity of the protective shell 101, a detection camera 105 is slidably arranged inside the electric guide rail 104, and an extrusion focusing mechanism 2 is arranged on the side of the protective shell 101;

[0043] The squeezing focusing mechanism 2 includes a support frame 201 fixedly arranged on the side of the protective shell 101, an external motor 202 is fixedly arranged on the side of the support frame 201, a bidirectional screw rod 203 is fixedly arranged on the output shaft of the external motor 202, two groups of moving blocks 204 are threaded on the outer annular surface of the bidirectional screw rod 203, a light-transmitting mirror 208 is rotatably arranged at the bottom of the moving block 204, and a light source 303 is arranged inside the protective shell 101. The two groups of light-transmitting mirrors 208 can be squeezed by the relative movement of the two groups of moving blocks 204, so that the inside of the dark connector 103 can be focused.

[0044] Specifically, although the existing device can complete the detection of connectors, when detecting dark-colored connectors, since the surface of dark-colored connectors is darker in color and has a stronger ability to absorb light, most of the light will be absorbed when projected onto the dark surface, and only a small part can be reflected back to the sensor of the scanner. Therefore, when the reflected light signal received by the scanner is weak, the device cannot accurately capture all the details of the connector, resulting in reduced detection accuracy. At the same time, in order to compensate for the lack of information caused by the weak reflected light signal, the 3D detection device needs a longer exposure time or scans the same area multiple times to collect sufficient data, which will slow down the detection speed and reduce production efficiency.

[0045] Therefore, the present invention solves this problem by setting a certain structure. When inspection is required, the connector 103 is first placed on the positioning clamp 102 for positioning. At this time, the electric guide rail 104 fixedly set at the bottom of the inner cavity of the protective shell 101 will be started, and when started, it will drive the inspection camera 105 slidably connected therein to move synchronously and start the inspection camera 105 and the light source 303 before moving to inspect the connector 103. However, since the surface of the dark-colored connector is darker in color and has a stronger ability to absorb light, this will cause most of the light to be absorbed when it is projected onto the dark surface, and only a small part can be reflected back to the sensor of the scanner. Therefore, when the reflected light signal received by the scanner is weak, the device The device cannot accurately capture all the details of the connector, resulting in a decrease in detection accuracy. At this time, the external motor 202 fixed on the side of the support frame 201 is started to rotate its output shaft, and at the same time, it drives the bidirectional lead screw 203 fixed thereto to rotate synchronously. Since the two groups of moving blocks 204 are both threadedly connected to the outer ring surface of the bidirectional lead screw 203, the two groups of moving blocks 204 will be driven to move toward the middle of the bidirectional lead screw 203 when the bidirectional lead screw 203 rotates, and at the same time, the two groups of light-transmitting mirrors 208 are squeezed to form a convex lens-like state, so that the light inside the dark connector 103 can be gathered, and more light can be directed to the inside of the connector, thereby improving the detection accuracy.

[0046] like Figure 4 and Figure 7 As shown, the squeezing focusing mechanism 2 in this embodiment includes a support frame 201, the external motor 202 is fixedly arranged on the side of the support frame 201, the bidirectional screw rod 203 is fixedly connected to the output shaft of the external motor 202, and the moving block 204 is threadedly connected to the outer ring surface of the bidirectional screw rod 203.

[0047] Specifically, when the dark connector 103 needs to be inspected, the external motor 202 is started. At this time, the output shaft of the external motor 202 will rotate, and at the same time, it will drive the bidirectional screw rod 203 fixed with its output shaft to rotate synchronously. Since the two groups of moving blocks 204 are respectively connected to the two ends of the bidirectional screw rod 203, when the bidirectional screw rod 203 rotates, it will drive the two groups of moving blocks 204 to move synchronously.

[0048] like Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, in this embodiment, the moving block 204 is fixedly connected to the first guide block 205 on the side, and the first limiting groove 206 is opened on the side of the support frame 201 in the vertical direction. The first guide block 205 is slidably connected to the inside of the first limiting groove 206, and the end of the moving block 204 away from the first guide block 205 is fixedly connected to the sliding baffle 207, and the bottom of the moving block 204 is rotatably provided with a light-transmitting mirror 208, and the light-transmitting mirror 208 is provided with two groups, and the side of the support frame 201 is fixedly connected to a guide block 209, and the end of the guide block 209 away from the support frame 201 is between the two groups of light-transmitting mirrors 208, and the top of the electric telescopic rod 302 is fixedly provided with a light source 303.

[0049] Specifically, when the bidirectional screw rod 203 rotates, it will drive the two groups of moving blocks 204 to move synchronously. Since the first guide blocks 205 are fixed on the sides of the two groups of moving blocks 204, and the first guide blocks 205 slide inside the first limiting groove 206, when the bidirectional screw rod 203 rotates, the moving blocks 204 limited by the first limiting groove 206 will perform relative linear motion, and will squeeze the two groups of light-transmitting mirrors 208 while moving. Due to the guide blocks 209 set in the middle of the two groups of light-transmitting mirrors 208, it can avoid the two groups of light-transmitting mirrors 208 from bending inward when being squeezed, so that The light emitted by the light source 303 is focused on the inside of the dark connector 103. When the moving block 204 moves, it will drive the sliding baffle 207 fixed thereto to move synchronously. During the movement, the sliding baffle 207 will gradually unfold, thereby preventing the light from being emitted outward when the two sets of light-transmitting mirrors 208 are squeezed. At this time, the light can be gathered by the bending of the middle parts of the two sets of light-transmitting mirrors 208 towards each other, and then more light can be directed to the inside of the connector, thereby improving the accuracy of detection. This enables inspectors to more accurately judge the structure and materials inside the connector and whether there are defects.

[0050] like Figure 3 and Figure 8 As shown, the detection device 1 described in this embodiment is internally provided with an adjustment mechanism 3 for adjusting the focus position, and the adjustment mechanism 3 includes a limit frame 301, and the limit frame 301 is fixedly connected to the upper part of the detection camera 105, and an electric telescopic rod 302 is fixedly provided on the upper part of the detection camera 105, and the light source 303 is slidably connected to the limit frame 301, and a second limit groove 304 is opened on the lower side of the limit frame 301, and a cleaning plate 305 is slidably connected inside the second limit groove 304.

[0051] like Fig. 9 and Fig.10As shown, in this embodiment, a conveyor belt 307 is fixedly connected to the side of the cleaning plate 305, and a rotating column 306 is rotatably connected inside the conveyor belt 307. An inner cavity is opened at the bottom of the limit frame 301, and the rotating column 306 is rotatably connected to the side wall of the inner cavity of the limit frame 301. A trigger adjustment block 309 is fixedly connected to the other side of the conveyor belt 307, and a third limiting groove 308 is opened on the side of the limit frame 301 away from the conveyor belt 307, and the trigger adjustment block 309 is slidably connected inside the third limiting groove 308.

[0052] Specifically, when there are gathered pins in the corner of the dark connector 103, in the initial state, the light source 303 is located in the middle of the limit frame 301. At this time, the light source 303 and the protruding part formed by the two sets of light-transmitting mirrors 208 are on the same horizontal line. At this time, the electric telescopic rod 302 is started, and the electric telescopic rod 302 drives the light source 303 fixed thereto to move along the guide of the limit frame 301, so that the position of the light source 303 can be adjusted, and then the position where the light is focused can be adjusted, so that the light is focused on the pin area, which can enhance the lighting intensity of the area, thereby improving the visibility and recognition of the pins. At the same time, when the detection is completed, the light source 303 will return to the initial state driven by the electric telescopic rod 302. At this time, the electric telescopic rod 302 is driven to move the light source 303 fixed thereto. 02 will drive the light source 303 to continue to move downward along the direction of the limit frame 301. When the bottom of the light source 303 contacts the upper part of the trigger adjustment block 309, the trigger adjustment block 309 will be squeezed to move along the guide of the third limit groove 308. When the trigger adjustment block 309 moves, the conveyor belt 307 will be driven to transmit, and the cleaning plate 305 on the other side will be driven to move upward during the transmission. When the trigger adjustment block 309 and the cleaning plate 305 are on the same horizontal plane, the cleaning plate 305 and the lampshade of the light source 303 are tightly fitted. At this time, the electric telescopic rod 302 will continue to move downward, and the synchronous cleaning plate 305 will continue to move upward, so that the lampshade of the light source 303 can be wiped, thereby improving the effect of the next detection.

[0053] Embodiment 2

[0054] like Figures 1 to 9 As shown, compared with Example 1, another embodiment of the present invention is: a 3D detection method for a connector, the specific steps include:

[0055] Equipment preparation and debugging: Conduct a comprehensive inspection of the testing equipment before use, and install the corresponding testing software according to the equipment requirements;

[0056] Sample preparation and placement: According to the requirements of the test, select the corresponding connector 103, clean the connector 103, and place the connector 103 on the positioning clamp 102 after cleaning;

[0057] Operation implementation: Start the measurement program and start the light source 303 to fill the connector with light. When encountering a dark connector 103, the two sets of external motors 202 are driven to move toward each other through the rotation of the bidirectional screw rod 203, and the two sets of light-transmitting mirrors 208 are squeezed to make the two sets of light-transmitting mirrors 208 present a convex lens-like state, so that the light inside the dark connector 103 being tested can be focused;

[0058] Data Analysis: When the inspection is completed, the collected data will be processed and analyzed to evaluate the quality and performance of the connector and generate an analysis report for subsequent use.

[0059] The operation is implemented specifically as follows: first, the connector 103 is placed on the upper part of the positioning clamp 102 for fixing, and then the detection camera 105 and the electric telescopic rod 302 are started. At this time, the light will shine on the connector 103 through the two sets of uncompressed light-transmitting mirrors 208, and the external motor 202 is started at the same time. At this time, the two sets of moving blocks 204 connected to the external motor 202 will move toward the middle of the two-way screw rod 203 at the same time, and then drive the sliding baffle 207 to move synchronously. During the movement, since the two sets of light-transmitting mirrors 208 are made of flexible materials and are resisted by the guide block 209, they will protrude outward synchronously, thereby forming the effect of a double-sided convex lens, so that the interior of the dark-colored connector 103 can be focused.

[0060] Working principle: when the dark connector 103 needs to be inspected, the external motor 202 is started. At this time, the output shaft of the external motor 202 will rotate, and at the same time, it will drive the bidirectional screw rod 203 fixed with its output shaft to rotate synchronously. Since the two groups of moving blocks 204 are respectively connected to the two ends of the bidirectional screw rod 203, the two groups of moving blocks 204 will be driven to move synchronously when the bidirectional screw rod 203 rotates.

[0061] When the bidirectional screw rod 203 rotates, it will drive the two groups of moving blocks 204 to move synchronously. Since the first guide blocks 205 are fixed on the sides of the two groups of moving blocks 204, and the first guide blocks 205 slide inside the first limiting groove 206, when the bidirectional screw rod 203 rotates, the moving blocks 204 limited by the first limiting groove 206 will perform relative linear motion, and will squeeze the two groups of light-transmitting mirrors 208 while moving. Due to the guide blocks 209 set in the middle of the two groups of light-transmitting mirrors 208, it can avoid the two groups of light-transmitting mirrors 208 from bending inward when being squeezed, so that the light source can be The light emitted by 303 is focused on the inside of the dark connector 103. When the moving block 204 moves, it will drive the sliding baffle 207 fixed thereto to move synchronously. During the movement, the sliding baffle 207 will gradually unfold, thereby preventing the light from emitting outward when the two sets of light-transmitting mirrors 208 are squeezed. At this time, the light can be gathered by the bending of the middle parts of the two sets of light-transmitting mirrors 208 towards each other, and then more light can be directed to the inside of the connector, thereby improving the accuracy of detection, which enables the inspectors to more accurately judge the structure and materials inside the connector and whether there are defects.

[0062] When there are gathered pins in the corner of the dark connector 103, in the initial state, the light source 303 is located in the middle of the limit frame 301. At this time, the light source 303 and the protruding part formed by the two sets of light-transmitting mirrors 208 are on the same horizontal line. At this time, the electric telescopic rod 302 is started, and the electric telescopic rod 302 drives the light source 303 fixed thereto to move along the guide of the limit frame 301, so that the position of the light source 303 can be adjusted, and then the position where the light is focused can be adjusted, so that the light is focused on the pin area, which can enhance the lighting intensity of the area, thereby improving the visibility and recognition of the pins. At the same time, when the detection is completed, the light source 303 will return to the initial state driven by the electric telescopic rod 302. At this time, the electric telescopic rod 302 It will drive the light source 303 to continue to move downward along the direction of the limit frame 301. When the bottom of the light source 303 contacts the upper part of the trigger adjustment block 309, it will squeeze the trigger adjustment block 309 to move along the guide of the third limit groove 308. When the trigger adjustment block 309 moves, it will drive the conveyor belt 307 to transmit, and drive the cleaning plate 305 on the other side to move upward during the transmission. When the trigger adjustment block 309 and the cleaning plate 305 are on the same horizontal plane, the cleaning plate 305 and the lampshade of the light source 303 are tightly fitted. At this time, the electric telescopic rod 302 will continue to move downward, and the synchronous cleaning plate 305 will continue to move upward, so that the lampshade of the light source 303 can be wiped, thereby improving the effect of the next detection.
