Description

Technical Field

[0001] The invention relates to the field of appearance detection of key caps, and in particular to a key cap detection device. Background Art

[0002] The inspection of keyboard keycaps includes quality inspection, color consistency, and whether there are obvious scratches or wear on the keyboard surface. At the same time, it is also necessary to pay attention to whether the overall structure of the keyboard is firm, whether the keycaps are easy to loosen, key life test, sensitivity test. For a high-quality computer keyboard, key sensitivity and key life are very important factors.

[0003] In the keyboard manufacturing, the keycaps need to be assembled and printed to display the familiar letters a-ζ, numbers and some special symbols. However, during the assembly and printing, it is easy to make assembly errors and dirty printing. We will inspect the appearance of the keyboard, including the dark marks, pits, particles and dandruff of the keycaps, to ensure the qualified rate of the product. The traditional inspection method is our most basic manual inspection, which depends entirely on actual work experience. However, the large number of keycaps and the diversity of printing not only increase the labor intensity of workers, but also reduce the accuracy and efficiency.

[0004] At present, the most widely used machine for keyboard appearance inspection is the keycap appearance visual inspection machine. It uses an industrial camera to take a picture of the keyboard for identification, and adopts advanced integrated structured light technology in imaging and advanced AI deep learning technology in software algorithm. The staff locks the keyboard on the rotating workbench, and the workbench drives the keyboard to rotate to the inside of the keycap appearance visual inspection machine. Then the industrial camera takes a picture of the keyboard for identification and uploads the data to the system. The identified data is compared through the software algorithm to determine whether the appearance of the keycap is qualified.

[0005] The rotating workbench of the keycap appearance visual inspection machine is usually equipped with multiple workstations to ensure that the staff can load materials and take photos for identification at the same time. Because the rotating workbench drives the keyboard to rotate, a positioning block is set above the rotating workbench. It can not only prevent the keyboard from slipping during rotation, but also accurately locate the position of the keyboard, thereby improving the accuracy of industrial camera photography. However, in the actual working process, the staff's assistance and participation are required, which reduces the inspection efficiency. Summary of the invention

By setting the multi-angle optical inspection mechanism 2, the angle of the industrial camera 203 can be freely adjusted, so that the optical inspection of the keyboard is more accurate.

[0057] The present invention is used in specific operation: when an enterprise needs to conduct appearance inspection on a batch of keyboards, it first needs to carry out preparation work. The staff will respectively snap and install multiple keyboard fixing molds 8 into the mold snap bracket 702 of the material frame 7, and then adjust and calibrate the keyboard fixing mold 8. After the keyboard fixing mold 8 is installed and snapped into the mold snap bracket 702, the adjustment block 8086 will be attached to one side of the mold snap bracket 702, and then the rotation of the second threaded rod 8087 will drive the fixing block 8084 to move along the outside of the second threaded rod 8087, that is, drive the fixing block 8084 and the connecting rod 8083 to move. , the clamping plate 8082 and the strip plate 8081 are moved. This step is used to adjust the initial position of the clamping assembly 808, that is, to adjust the distance between the clamping plates 8082 of the two sets of clamping assemblies 808 to match the length of the keyboard, so as to ensure that when the keyboard fixing mold 8 slides out of the mold clamping bracket 702, the side of the mold clamping bracket 702 no longer restricts the adjustment block 8086, and the two sets of clamping plates 8082 will approach each other under the resetting action of the second spring 8085 to clamp the keyboard, and then according to the width of the keyboard, the first threaded rod 804 is rotated to adjust the position of the limit plate 803.

[0058] When the adjustment of multiple groups of keyboard fixing molds 8 installed in the material frame 7 is completed, take a group of keyboard fixing molds 8 for engaging the keyboard as an example: the staff will move the long side of the keyboard to be tested from the semi-arc groove 809 position of the keyboard fixing mold 8 against the side of the limit plate 803, and then place the keyboard horizontally on the two groups of supporting plates 806. According to the above method, the keyboards to be tested are placed in the multiple groups of keyboard fixing molds 8 engaged in the material frame 7. Then the staff will transfer the material frame 7 filled with the keyboard to the top of a group of mold mounting tables 506. The material frame 7 is engaged between the two groups of second positioning blocks 507. Then, another group of material frames 7 is filled in the same way and placed on the top of another group of mold mounting tables 506. The two groups of mold mounting tables 506 are used for loading at the same time to ensure that the equipment does not stop working. Then, the two groups of empty material frames 7 are placed in the keyboard unloading mechanism 6 in the same way.

[0059] Next, the second driving device is started to drive the first screw rod 504 to rotate, thereby adjusting the height of the lifting platform 503, and the third driving device is started to drive the second screw rod 508 to rotate, thereby adjusting the horizontal position of the mold mounting table 506, that is, adjusting the horizontal position and height of the material frame 7 filled with keyboards, ensuring that the top group of keyboard fixing molds 8 in the material frame 7 are flush with the pushing plate 10 at the end of the second telescopic cylinder 9, and the second telescopic cylinder 9 is started to drive the pushing plate 10 to move, and then the pushing plate 10 pushes the top group of keyboard fixing molds 8 in the material frame 7 to move. After the keyboard fixing mold 8 slides out of the corresponding mold clamping bracket 702, the second springs 8085 of the two sets of clamping assemblies 808 will be reset, and then the clamping assembly 808 as a whole will be in the mold The keyboard body 801 is moved upward, and the adjustment block 8086 is also attached to the side of the mold body 801. That is, when the keyboard fixing mold 8 slides out from the corresponding mold clamping bracket 702, the two sets of clamping plates 8082 are close to each other to clamp and fix the keyboard. Since a protective block is usually installed at the bottom of the keyboard and the friction is relatively large, two sets of movable supporting plates 806 are set to hold the keyboard. Even if there is a deviation in the placement of the keyboard due to human factors, when the two sets of clamping plates 8082 clamp the keyboard, the positions of the keyboard and the two sets of supporting plates 806 will be adjusted together. In summary, when the keyboard fixing mold 8 slides out from the corresponding mold clamping bracket 702 and enters the mold positioning mechanism 4, the keyboard fixing mold 8 will automatically clamp the keyboard.

[0060] As the keyboard fixing mold 8 moves, the T-shaped limit block 810 at the bottom of the keyboard fixing mold 8 will smoothly engage with the T-shaped slot 404, and then the keyboard fixing mold 8 will begin to move into the mold positioning mechanism 4. During the movement, the keyboard fixing mold 8 will squeeze the movable block 4052, and the movable block 4052 will shrink toward the inside of the square tube 4051 and compress the first spring 4055, and then the keyboard fixing mold 8 will move smoothly and fit with the two groups of first positioning blocks 402. When the keyboard fixing mold 8 fits with the first positioning block 402, the movable block 4052 will extend out from the square tube 4051 again under the resetting action of the first spring 4055, thereby limiting one side of the keyboard fixing mold 8.

[0061] Next, start the first driving device to drive the cross workbench 3 to rotate, so that the mold positioning mechanism 4 with the keyboard fixing mold 8 engaged on the top of the cross workbench 3 rotates to the inside of the keycap appearance visual inspection machine 1, and start the three-axis linkage assembly 201 to adjust the position of the rotating device 202. At the same time, start the rotating device 202 to adjust the angle of the industrial camera 203, and use the industrial camera 203 to take pictures of the keyboard for recognition, and then upload the obtained data to the system, and use the software algorithm to compare the appearance of the keyboard to determine whether the appearance of the keyboard is qualified. After the keyboard inspection is completed, the first driving device continues to drive it to rotate to one side of the keyboard unloading mechanism 6. The working principle of the keyboard unloading mechanism 6 is the same as that of the keyboard loading mechanism 5. After the position adjustment of the empty material frame 7 is completed , the first telescopic cylinder 406 at the bottom of the mounting plate 401 works to push the connecting plate 407 to move, and then the connecting plate 407 drives the L-shaped plate 408 and the linkage plate 409 to move, and the linkage plate 409 first acts on the movable limit assembly 405 to shrink the movable block 4052, and then the L-shaped plate 408 pushes the keyboard fixing mold 8 back to the mold clamping bracket 702 of the empty material frame 7. When the keyboard fixing mold 8 reaches the mold clamping bracket 702, the keyboard fixing mold 8 will release the clamping of the keyboard, so that the staff can take the material more easily. The two groups of empty material frames 7 in the keyboard unloading mechanism 6 can be used to store qualified and unqualified keyboards respectively. The loading and unloading of the keyboard are automatically completed by the equipment, and the loading, testing and unloading of the keyboard can be carried out at the same time.
