Description

Technical Field

[0001] This utility model relates to the field of electric vehicle charging connectors, specifically a CCD measuring fixture for an electric vehicle charging connector after electroplating. Background Technology

[0002] Electric vehicle charging connectors, as electrical connection devices between electric vehicles and external power sources, are key components for realizing power transmission. Their performance directly affects the safety, stability, and efficiency of charging. They not only need to have good conductivity and mechanical strength, but also meet stringent requirements such as waterproofing, dustproofing, and resistance to plugging and unplugging. With the rapid development of the electric vehicle industry, quality control of charging connectors is becoming increasingly important.

[0003] Currently, CCD measuring fixtures play an important role in the inspection of electroplated electric vehicle charging connectors. These fixtures are specifically designed for the size and appearance inspection of electroplated electric vehicle charging connectors and are equipped with a high-precision CCD vision system. Through this system, the key dimensions of the charging connector can be measured quickly and accurately, while accurately identifying various defects on the surface and evaluating the quality of electroplating, thus providing an effective inspection method for ensuring the quality of charging connectors.

[0004] However, in practical applications of industrial CCDs for dimensional measurement of workpieces in the industrial field, for most standardized measurement scenarios, since the position of the CCD measuring fixture is fixed, when measuring car charging connectors, it is necessary to manually determine the X-axis, Y-axis and other coordinate references for each workpiece being measured. This not only makes the operation process cumbersome, but also leads to low detection efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a CCD measuring fixture for electric vehicle charging connectors after electroplating, so as to solve the technical problem of low detection efficiency of current industrial CCDs for detecting electric vehicle charging connectors.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CCD measuring fixture for an electric vehicle charging connector after electroplating, comprising a measuring platform, a fixed frame inside the measuring platform, a glass plate fixed to the top of the fixed frame, a mold on the top of the glass plate, a first slide rail and a second slide rail inside the measuring platform, a mounting bracket sleeved on the outer surface of the second slide rail, a lens mounted at the end of the mounting bracket, an industrial control computer on the inner wall of the measuring platform, a display screen mounted on the inner wall of the measuring platform, and the lens, the display screen and the industrial control computer connected by wires.

[0007] By adopting the above technical solution, the problem of low detection efficiency of current industrial CCDs for detecting electric vehicle charging connectors is solved. Personnel control the industrial control computer through the detection software system inside the display screen. The industrial control computer sends control commands to the first and second slide rails, causing the lens to move horizontally along the first and second slide rails and take images at each placement slot. The images are then fed back to the industrial control computer, which processes the feedback images based on the image pixels and compares the processing results with the data stored in the industrial control computer to determine whether the workpiece meets the dimensional requirements. Furthermore, it eliminates the need for manual coordinate reference each time, thereby speeding up the detection rate.

[0008] The present invention is further configured such that both the first slide rail and the second slide rail are composed of three parts: a driving device, a transmission mechanism, and a guiding mechanism.

[0009] Preferably, the industrial computer sends instructions to the motion control card according to the preset coordinates of the marked hole positions. The motion control card converts the instructions into pulse signals and transmits them to the motor driver through wires. After receiving the signal, the motor driver drives the motor to rotate. The power of the motor rotation is transmitted to the mounting bracket through the transmission mechanism, thereby enabling the mounting bracket to move linearly along the axis of the second slide rail.

[0010] The present invention is further configured such that one end of the second slide rail is located on the first slide rail, and the internal components of the first slide rail can drive the second slide rail to move.

[0011] Preferably, the end of the second slide rail is connected inside the first slide rail. When the lens needs to move along the axis of the first slide rail, the first slide rail can drive the second slide rail, causing the second slide rail to move the lens.

[0012] The present invention is further configured such that the interior of the fixed frame is provided with multiple sets of lighting lamps, and the lighting lamps are arranged at equal intervals.

[0013] Preferably, the lighting provides illumination for the lens to inspect the device placed on the template.

[0014] The present invention is further configured such that the mold is made of acrylic sheet, and the top of the mold is provided with multiple sets of placement slots, which are arranged in a linear array.

[0015] Preferably, the acrylic sheet has good light transmittance, allowing the light emitted by the lamp to be projected onto the charging connector through the template, thereby enabling the lens to clearly capture an image of the light transmission gap of the charging connector.

[0016] The present invention is further configured such that both ends of the placement groove are provided with grooves, and the width of the grooves is greater than the diameter of the placement groove.

[0017] Preferably, after the charging connector has been tested, personnel can remove the charging connector placed inside the placement slot from the groove.

[0018] The present invention is further provided that extrusion blocks are installed on both sides of the inner wall of the placement groove, and the extrusion blocks are made of silicone material.

[0019] Preferably, when the charging connector is placed inside the placement slot, the extrusion blocks on both sides of the inner wall of the placement slot extrude and fix the charging connector, and the silicone extrusion blocks have good elasticity, thereby reducing the extrusion damage to the charging connector.

[0020] The present invention is further configured such that a spring is installed at one end of the extrusion block, and the spring has an elastic coefficient of 1 N / mm.

[0021] Preferably, when the charging connector presses and pushes the pressing block, the pressing block will press and retract the spring, and the spring will also give the pressing block a reaction force, so that the pressing block presses and fixes the charging connector. The spring constant is 1N / mm. This constant can ensure the stable clamping of the pressing block while avoiding excessive compression that could damage the plating on the outer wall of the charging connector.

[0022] The present invention is further configured such that limiting plates are provided on both sides of the extrusion block, and limiting grooves are provided inside the template.

[0023] Preferably, during the movement of the extrusion block, the limiting groove inside the mold limits and controls the movement distance of the extrusion block through the limiting plate.

[0024] In summary, the present invention has the following main advantages: This invention solves the problem of low detection efficiency in current industrial CCD testing of electric vehicle charging connectors by setting up a measuring platform, mold, first slide rail, second slide rail, lens, upper display screen, and industrial control computer. The industrial control computer sends control commands to the first and second slide rails, causing the lens to move horizontally along the first and second slide rails and capture images at each placement slot. The images are then fed back to the industrial control computer, which processes the feedback images based on the image pixels and compares the processing results with pre-stored data to determine whether the workpiece meets the dimensional requirements. Furthermore, it eliminates the need for manual coordinate reference each time, thus accelerating the detection rate.

[0025] This invention incorporates a pressing block, a spring, a limiting groove, and a limiting plate. When the charging connector is placed inside the placement groove, the charging connector pushes the pressing blocks on both sides of the inner wall of the placement groove to the sides. During the movement of the pressing block, the pressing block compresses and contracts the spring, and the spring also applies a reaction force to the pressing block, causing the pressing block to compress and fix the charging connector.

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] First embodiment: Please see Figure 1 — Figure 5The system includes a measuring platform 1, an internal fixed frame 2, a glass plate 3 fixed to the top of the fixed frame 2, a mold 4 on the top of the glass plate 3, a first slide rail 5 and a second slide rail 6 inside the measuring platform 1, a mounting bracket 7 fitted onto the outer surface of the second slide rail 6, a lens 8 mounted at the end of the mounting bracket 7, an industrial control computer 18 mounted on the inner wall of the measuring platform 1, and a display screen 9 mounted on the inner wall of the measuring platform 1. The lens 8, the display screen 9, and the industrial control computer 18 are connected by wires. This system solves the problem of low detection efficiency in current industrial CCD testing of electric vehicle charging connectors. The industrial control computer 18 is controlled by the detection software system inside the display screen 9. The industrial control computer 18 sends control commands to the first slide rail 5 and the second slide rail 6, causing the lens 8 to move horizontally along the first slide rail 5 and the second slide rail 6 and take pictures at each placement slot 11. The images are then fed back to the industrial control computer 18. The industrial control computer 18 processes the feedback images based on the image pixels and compares and analyzes the processing results with the data pre-stored in the industrial control computer 18 to determine whether the workpiece meets the dimensional requirements. This eliminates the need for manual coordinate reference each time, thereby speeding up the detection rate.

[0031] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The first slide rail 5 and the second slide rail 6 are both composed of three parts: a drive device, a transmission mechanism, and a guide mechanism. The industrial control computer 18 sends instructions to the motion control card according to the preset coordinates of the marked hole positions. The motion control card converts the instructions into pulse signals and transmits them to the motor driver through wires. After receiving the signal, the motor driver drives the motor to rotate. The power of the motor rotation is transmitted to the mounting frame 7 through the transmission mechanism, thereby enabling the mounting frame 7 to move linearly along the axis of the second slide rail 6.

[0032] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 One end of the second slide rail 6 is located on the first slide rail 5, and the internal components of the first slide rail 5 can drive the second slide rail 6 to move. The end of the second slide rail 6 is connected to the inside of the first slide rail 5. When the lens 8 needs to move along the axis of the first slide rail 5, the first slide rail 5 can drive the second slide rail 6, so that the second slide rail 6 can drive the lens 8 to move.

[0033] For details regarding the above embodiments, please refer to [link / reference]. Figure 3 The fixed frame 2 is equipped with multiple sets of lighting lamps 10, and the lighting lamps 10 are evenly spaced. The lighting lamps 10 provide light for the lens 8 to detect the device placed on the template 4.

[0034] For details regarding the above embodiments, please refer to [link / reference]. Figure 4The mold 4 is made of acrylic sheet. The top of the mold 4 is provided with multiple sets of placement slots 11, and the multiple sets of placement slots 11 are arranged in a linear array. The acrylic sheet has good light transmittance, so that the light emitted by the lighting lamp 10 can be projected onto the charging connector through the template 4, thereby enabling the lens 8 to clearly capture the light transmission gap image of the charging connector.

[0035] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The two ends of the placement slot 11 are provided with grooves 13, and the width of the grooves 13 is greater than the diameter of the placement slot 11. After the charging connector has been tested, the personnel can take out the charging connector placed inside the placement slot 11 from the grooves 13.

[0036] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 The inner walls of the placement groove 11 are equipped with extrusion blocks 12 on both sides, and the extrusion blocks 12 are made of silicone. When the charging connector is placed inside the placement groove 11, the extrusion blocks 12 on both sides of the inner walls of the placement groove 11 extrude and fix the charging connector. The silicone extrusion blocks 12 have good elasticity, which can reduce the extrusion damage to the charging connector.

[0037] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 A spring 14 is installed at one end of the extrusion block 12, and the elastic coefficient of the spring 14 is 1N / mm. When the charging connector pushes the extrusion block 12, the extrusion block 12 will compress and retract the spring 14. At the same time, the spring 14 will also give the extrusion block 12 a reaction force, so that the extrusion block 12 presses and fixes the charging connector. The elastic coefficient of the spring 14 is 1N / mm. This elastic coefficient can ensure the stable clamping of the extrusion block 12 within the compression stroke of 15mm, while avoiding excessive extrusion that could damage the plating on the outer wall of the charging connector.

[0038] For details regarding the above embodiments, please refer to [link / reference]. Figure 5 Limiting plates 16 are provided on both sides of the extrusion block 12, and limiting grooves 15 are opened inside the mold 4. During the movement of the extrusion block 12, the limiting grooves 15 inside the mold 4 limit and control the movement distance of the extrusion block 12 through the limiting plates 16.

[0039] Second embodiment: Please see Figure 6A gasket 17 is installed at the bottom of the mold 4, and the gasket 17 is made of neoprene rubber. The neoprene rubber gasket 17 can increase the friction between the mold 4 and the glass plate 3. When the fixed frame 2 vibrates, the gasket 17 at the bottom of the mold 4 can absorb the shock wave and reduce the sliding of the mold 4 on the glass plate 3. In addition, the gasket 17 is set at the four corners of the bottom of the mold 4, so that the gasket 17 will not block the light emitted by the lamp 10 from passing through the mold 4 to the charging connector in the placement slot 11.

[0040] In practical operation, this invention works as follows: First, multiple charging connectors are placed in the placement groove 11 inside the mold 4. During the placement process, the operator places the charging connector above the placement groove 11 and then presses it down, causing the charging connector to push the extrusion blocks 12 on both sides of the inner wall of the placement groove 11 to the sides. During the movement of the extrusion blocks 12, the extrusion blocks 12 compress the compression spring 15, and the spring 15 also applies a reaction force to the extrusion blocks 12, causing the extrusion blocks 12 to compress and fix the charging connector. Then, the mold 4 containing the charging connector is placed on the glass plate 3 inside the measuring table 1. Multiple sets of lighting lamps 10 are installed inside the fixing frame 2. The light emitted by the lighting lamps 10 shines through the glass plate 3 onto the charging connector placed in the mold 4. The operator opens the detection software through the display screen 9 and starts the industrial control computer 18 through the detection software. The industrial control computer 18 sends control commands to the first slide rail 5 and the second slide rail 6 respectively. The first slide rail 5 and the second slide rail 6 are connected by the extrusion blocks 12 to the measuring table 1. The mounting frame 7 drives the lens 8 to translate along the X and Y axes (the first slide rail 5 and the second slide rail 6 are both composed of three parts: a drive device, a transmission mechanism, and a guide mechanism. When the mounting frame 7 moves along the axis of the second slide rail 6, the industrial control computer 18 sends a command to the motion control card according to the preset coordinates of the marked hole position. The motion control card converts the command into a pulse signal and transmits it to the motor driver through the wire. After receiving the signal, the motor driver drives the motor to rotate. The power of the motor rotation is transmitted to the mounting frame 7 through the transmission mechanism, thereby realizing that the mounting frame 7 moves linearly along the axis of the second slide rail 6). The lens 8 also captures the light transmission gap image of the charging connector at each placement slot 11 on the mold 4. The light transmission gap image is then fed back to the industrial control computer 18. The industrial control computer 18 has preset spacing of each charging connector placement area of ​​the calibration fixture. The industrial control computer 18 processes the image in combination with the light transmission gap image and compares and analyzes the processing result with the data stored in the industrial control computer 18 to determine whether the charging connector meets the size requirements.
