1. Solution 1: The first driving member is used to drive the second driving member and the push block to move along the rotation axis of the workpiece at the working position, so that the output end of the second driving member moves toward the connecting member and cooperates with the first driving member. Establish an anti-rotation cooperation relationship.

3. Option 3: The fixed part is inserted into the hole of the workpiece to support the workpiece and increase the assembly force of the workpiece on the fixed part to prevent easy detachment.

4. Option 4, a detection device. The detection device includes the above-mentioned transfer rotation device and a line scan detection mechanism. It includes a line scan camera. The receiving light of the line scan camera is in contact with the rotation axis of the relay semi-finished product when it is located at the line scan station. Perpendicular to each other, an image of the entire coil is obtained. When the jig is at the line scanning station, the second driving member drives the connecting member and drives the relay semi-finished product. The line scan camera acquires an image of the entire coil to evaluate the appearance of the coil of the relay semi-finished product. Carry out inspections to prevent the appearance of coils from being dirty or soldered, causing poor conductivity or vulnerability to the final product.

6. Option 6 uses a stripping bump to push the relay semi-finished product out of the jig. It can wait under the workpiece in advance and only needs to move up and back to remove the workpiece. Compared with the manipulator, it requires fewer steps to move up (or move forward), clamp and retreat, which is more efficient and will not damage the workpiece.

7. Option 7: There are multiple stripping bumps, and the third moving part is suitable for driving the first moving part to move in the second direction to switch each stripping bump to correspond to the relay semi-finished product of the OK product blanking station. In this way, multiple OK items can be collected and transferred to the OK item storage location in a unified manner, saving energy.

8. Plan 8: The first detection mechanism ensures that the substrate has no white edges, thus ensuring the strength of the substrate; the second detection mechanism prevents the pins from falling off in the subsequent process; the third detection mechanism prevents the mixing of materials from causing interference and prevention of the OK product unloading mechanism Product deformation causes subsequent assembly problems; the fourth and fifth detection mechanisms prevent poor conductivity; the sixth detection mechanism prevents pin bending from causing breakage during subsequent assembly and prevents the coil from being wound too much or too little to cause different magnetic fluxes of the same product. ; Thus, the interference of semi-finished product relays can be detected accordingly, product quality can be controlled at the semi-finished product stage, and process waste caused by NG products flowing to subsequent processes can be prevented.

9. Option 9: There are two driving devices, namely the first driving device and the second driving device. The first driving device is set corresponding to the work station of the third detection mechanism to drive the connecting piece corresponding to the work station to rotate and drive the relay. The semi-finished product is rotated so that the logo faces upward so that the subsequent inspection mechanism can obtain the desired image from above or below, which is more convenient. The second driving member is provided corresponding to the line scanning station and is configured to drive the connecting member corresponding to the station to rotate 360° and continue to rotate so that the opening of the stripping chute on the peripheral surface of the base body faces downward, thereby preventing OK products. The unloading mechanism interferes with the semi-finished product relay.

10. Plan 10: Set up sensors to prevent the incorrect posture of the semi-finished product relay caused by power outages, shutdowns, etc., and there is no subsequent driving device for adjustment. When the OK product blanking station is reached, the OK product blanking mechanism interferes with the semi-finished product relay. , causing damage.

However, after testing, whether there is dirt or soldering on the appearance of coil 52; the soldering condition of pin 53; and the injection molding of base body 51 status; the plugging status of the base 51 and the pin 53; whether the pin is perpendicular to the back angle of the base 51 and the diameter of the coil 52 will affect the service life and usage of the final product. The above missed detection will lead to poor conductivity of the final product or The problem of vulnerability, however, in the appearance inspection of finished products, it is impossible to detect the above appearance.

The loading mechanism is used to install the relay semi-finished product 5 to be tested on the jig 11 of the loading station, and the anti-rotation surface 512 and the anti-rotation part 1121 are anti-rotationally matched, and the fixed part 1122 is inserted into the iron core hole 511, thereby To realize the installation of the relay to be detected, the loading mechanism may be a robot hand.

Referring to Figures 12 to 15, since in the previous process, the pins 53 need to be inserted into the tin liquid for tin plating, therefore, when initially entering the detection device, the two pins 53 are facing downwards, and the stripping chute 513 is located on the base 51 The openings on the peripheral surface face upward.

The first detector is suitable for acquiring the front image of the base 51 to detect the injection molding status of the base 51 and ensure that the base 51 has no white edges, thus ensuring the strength of the base 51. The main acquired image is the dotted line in Figure 12.

The second detection mechanism is suitable for acquiring an image of the back of the base 51 to detect the insertion status of the base 51 and the pins 53 to prevent the pins 53 from falling off in the subsequent process; the main acquired image is the dotted line in Figure 13 .

The third detection mechanism is suitable for acquiring the top surface image of the base 51 to detect whether the base is deformed and the identification of the base 51 (located at the dotted line in the upper right corner of Figure 14) to prevent mixing, thereby preventing product deformation from causing subsequent assembly problems and Prevent mixing of materials from causing interference with the OK product unloading mechanism 4; as shown in Figure 14, the entirety of the relay semi-finished product 5;

The fourth detection mechanism is suitable for acquiring the top surface image of the base 51 to detect the soldering condition of the top pins 53 to prevent poor conductivity; the main acquired image is the dotted line in Figure 14 .

The fifth detection mechanism is suitable for acquiring the bottom surface image of the base 51 to detect the soldering condition of the bottom pins 53 to prevent poor conductivity; the line scan detection mechanism 2 includes a line scan camera that receives light and a relay. The rotation axis of the semi-finished product 5 is perpendicular when it is located at the line scanning station. The line scan camera is suitable for driving the connecting member 112 on the second driving part 122 and driving the entire rotation image of the semi-finished product 5 of the relay, so as to obtain an image of the coil 52 of the semi-finished product 5 of the relay. Detection is carried out to prevent the appearance of the coil 52 from being dirty or soldered, causing poor electrical conductivity or vulnerability to the final product.

The sixth detection mechanism is adapted to obtain the top surface image of the base 51 to detect whether the two pins 53 are perpendicular to the angle of the back of the base 51 (measure the angle α in Figure 15) and the diameter d of the coil 52, thereby preventing the pins from The bending of 53 causes breakage during subsequent assembly and prevents the coil 52 from being wound more or less, resulting in different magnetic fluxes of the same product; as shown in Figure 15.

After the above-mentioned testing mechanism transmits the image to be tested to the computer, the computer will capture the outline of the image to be tested, measure the data to be tested, or compare it with the image of the OK product to determine whether the relay semi-finished product 5 is OK or NG. The conclusion of the product is that the method of detecting appearance is similar to the method of detecting surface defects of objects in the prior art, so no further details will be given.

Referring to Figures 7-10, the OK product unloading mechanism 4 is suitable for unloading the relay semi-finished product 5 when the appearance of the relay semi-finished product 5 is determined to be OK; the OK product unloading mechanism 4 includes a first moving part 41, a second moving part 42, transfer plate 43 and third moving part 44; the first moving part 41 is suitable for driving the second moving part 42 to move along the rotation axis direction of the relay semi-finished product 5 located at the OK product blanking station; the transfer plate 43 is provided with There is a seating surface 431 and a stripping bump 432 protruding from the seating surface 431, a first guide plate 433, a second guide plate 434 and a limiting plate 435. The first guide plate 433 and the second guide plate 434 are spaced apart from each other. The limit plate 435 and the stripper bump 432 are arranged at intervals and are respectively used to block the forward and backward movement of the relay semi-finished product 5 relative to the transfer plate 43. The second moving part 42 is suitable for driving the transfer plate 43 to move in the vertical direction relative to the relay semi-finished product 5 to the third position; in the third position, the seating surface 431 is for the relay semi-finished product 5 to sit and the stripping bump 432 is inserted into the stripping chute 513. Therefore, the front end of the transfer plate 43 does not need to protrude from the relay semi-finished product 5 to apply a force to separate the relay semi-finished product 5. The transfer plate 43 saves more material, and because the front end of the transfer plate 43 does not need to protrude from the relay semi-finished product 5 , then the transfer plate 43 will not interfere with the connecting member 112 during the upward movement to prevent the risk of collision. The first moving part 41 is suitable for driving the second moving part 42 along the moving plate 43 when the moving plate 43 is in the third position. Rotate the axis direction and move in the direction away from the jig 11 so that the stripper bump 432 pushes the relay semi-finished product 5 out of the jig 11, through the stripper bump 432, the first guide plate 433, the second guide plate 434 and the limiter. The position plate 435 limits the position of the relay semi-finished product 5 in each direction, so that the relay semi-finished product 5 will only move horizontally when the material is removed, preventing the relay semi-finished product 5 from being tilted relative to the transfer plate 43 and causing the fixed part 1122 to scratch the relay semi-finished product 5 during the removal process. The iron core hole 511 or the fixed part 1122 is damaged. At the same time, the relay semi-finished product 5 after blanking is also positioned for subsequent transfer to prevent position uncertainty due to inertia during detachment, thereby inconvenient subsequent transfer. The OK product unloading mechanism 4 can wait under the workpiece in advance and only needs two steps of moving up and back to detach the workpiece. Compared with the manipulator, which needs to move up (or move forward), clamp and back up, there are fewer steps. It is more efficient and will not damage the workpiece.

In this embodiment, there are multiple stripping bumps 432 , and each stripping bump 432 is arranged along the second direction perpendicular to the rotation axis and the vertical direction. The first guide plate 433 , the second guide plate 434 and The number of limiting plates 435 matches the stripping bumps 432, that is, one relay semi-finished product 5 corresponds to a first guide plate 433, a second guide plate 434, a limiting plate 435 and a stripping bump 432; the third movement The member 44 is suitable for driving the first moving member 41 to move in the second direction to switch each stripping bump 432 to correspond to the relay semi-finished product 5 of the OK product blanking station, so that multiple OK products can be collected and transferred to the OK in a unified manner. storage area to save energy. The transfer of the relay semi-finished product 5 at the OK product unloading mechanism 4 to the OK product placement can be achieved by using a vertically moving manipulator to clamp the relay semi-finished product 5 and separate it from the transfer plate 43 before performing other movements.

The NG product unloading mechanism is suitable for unloading the relay semi-finished product 5 when the appearance of the relay semi-finished product 5 is determined to be NG. It can be a robot, and it can also have multiple unloading positions, so that multiple NG products can be collected. Carry out unified transfer to the place where NG products are placed to save energy.

In this implementation, there are two driving devices 12, namely a first driving device and a second driving device. The first driving device is arranged corresponding to the work station of the third detection mechanism to drive the connecting piece 112 corresponding to the work station to rotate and The relay semi-finished product 5 is driven to rotate until the mark faces upward, in this embodiment, it is rotated 90 degrees. At this time, the solder part of one pin 53 faces upward, and the solder part of the other pin 53 faces downward. By rotating the first driving device 90 degrees, the cameras of most subsequent work stations can obtain corresponding images by shooting from above and below. There is no need to shoot from the left and right sides, and shooting from the left and right sides will cause the multi-station turntable to be shot. 3 interferes, causing the camera to be unable to be arranged.

The second driving device is provided corresponding to the line scanning station and is configured to drive the connecting piece 112 corresponding to the station to rotate 360° and continue to rotate so that the opening of the stripping chute 513 on the peripheral surface of the base body 51 faces downward, thereby To prevent interference between the OK product unloading mechanism 4 and the semi-finished product relay, a total rotation of 450° is performed in this embodiment.

The timing of the sensor is before the timing corresponding to the OK product unloading mechanism 4 and after the timing corresponding to the sixth detection mechanism. The sensor detects the position of the stripping chute 513 on the circumferential surface of the base 51 by detecting the distance from the anti-rotation groove 11231. Whether the opening is facing downward, and a warning signal is issued when the opening of the stripping chute 513 on the peripheral surface of the base 51 is not facing downward. Specifically, in this embodiment, the sensor is used to emit laser light vertically, and the laser light emitted by the sensor is When passing through the anti-rotation groove 11231, the opening of the stripping groove 513 of the relay semi-finished product 5 on the peripheral surface of the base body 51 faces downward. peripheral surface, so the laser light can penetrate), what it detects is the distance to other objects, and the distance is larger. When the connecting member 112 rotates incorrectly, the laser light irradiates the peripheral surface of the connecting member 112 or the anti-rotation groove 11231 The distance between the groove walls is small, so by setting the detected distance interval, the posture of the connecting piece 112 at this time can be known, and thus the posture of the stripping chute 513 can be known.

The controller is electrically connected to the sensor and the alarm. When it receives the warning signal, it controls the alarm to alarm and pause the detection device, thereby preventing the OK product unloading mechanism 4 from impacting the product and causing damage.
