Description

Technical Field

[0001] The present invention relates to the technical field of key cap detection equipment, and in particular to a key cap appearance and structural surface integrated detection device. Background Art

[0002] Keyboard keycaps are divided into two sides, the front side is called the appearance side, which is a fingertip profiling surface with varying depths (convenient for positioning when typing a lot of keys quickly), and the back side is called the structural side, which has structures such as hooks, slides, or bosses, used to connect with the "scissor" structure. The appearance profiling surface will directly affect the feel of the keyboard, while the structural surface will affect the strength and service life of the keyboard. Therefore, it can be seen that the appearance inspection and structural surface inspection of the keycap are an indispensable part of the entire keyboard keycap manufacturing process.

[0003] Since the front and back of the keycaps are quite different and not a regular plane, in addition to the front and back, the sides around the keycaps also have strict size requirements. Therefore, the detection link must be high-precision, high-reliability, and capable of multi-faceted detection. In order to save costs, some companies use manual microscope detection, use finger sleeves to pick up and place the keycaps to be tested, and use microscopes to detect the product size and appearance, but it takes a long time, has high labor costs, and is not accurate enough. In order to solve the technical problems of keycap detection, some machines on the market can achieve all-round detection of keycaps. Such machines are generally completed by loading and unloading handling (handler), appearance surface detection, product flipping module, structural surface detection, side detection and other equipment. First, the loading and unloading handling (handler) places the keycaps to be tested at the test station, and the flipping module flips the keycaps on demand, cooperates with the light source and camera of the appearance surface, structural surface, and side detection station to take pictures, and compares them with the calibration image or data, and determines whether the keycaps meet the standards, so as to output and record the detection structure, which is convenient for the next step of keycap processing.

[0004] A Chinese patent with publication number CN109211938A discloses a keyboard keycap lifting detection device, including a frame, a main transmission line, a keycap character detection mechanism, a keycap shape detection mechanism, a keycap bottom detection mechanism, a suction transfer screening mechanism, a lifting mechanism and a reflow transmission line; the main transmission line, the keycap character detection mechanism, the keycap shape detection mechanism and the suction transfer screening mechanism are all located at the upper end of the middle table of the frame, the keycap bottom detection mechanism and the reflow transmission line are located below the middle table of the frame, and the lifting mechanism vertically penetrates the middle table of the frame; the keycap character detection mechanism, the keycap shape detection mechanism, the keycap bottom detection mechanism, the suction transfer screening mechanism and the lifting mechanism are arranged in sequence from the upstream end to the downstream end of the main transmission line. In this patent scheme, the appearance and internal structure of the keycap are detected by laser, and its positioning is required to be very accurate, and proofreading and positioning are often required, which makes the operation difficult.

[0031] It can be seen from the above scheme that the product is conveyed to the unloading end of the feeding module 2 through the feeding module 2, and is conveyed to the flipping module 4 by the conveying module 3. The flipping module 4 flips the product, and the flipped product is conveyed by the flipping module 4 to the first detection module 5 for photographic inspection of four sides. After the first round of inspection, the product is conveyed back to the flipping module 4 for resetting, and then the product is conveyed to the second detection module 6 via the conveying module 3 for photographic inspection of the appearance surface. After the second round of inspection is completed, it is conveyed to the feeding module 2 via the conveying module 3 for unloading.

[0032] A preferred solution is, Figure 3 As shown, the feeding module 2 includes a feeding motor 21 arranged on the frame and a feeding platform 22 drivingly connected to the feeding motor 21 .

[0033] It can be seen from the above scheme that the product is placed on the feeding platform 22 , and the feeding motor 21 drives the feeding platform 22 to move, so that the feeding platform 22 moves in a direction close to or away from the transport module 3 .

As shown in the figure, the bottom surface of the product is facing up at this time, and then the first rotary motor 512 rotates counterclockwise 90 degrees. The first detection component 52 completes the photo detection of the first side, and the second rotary motor 513 drives the product to rotate 90 degrees, 180 degrees and 270 degrees in sequence to realize the photo detection of the other three sides.
