[0002] As an important component of the compressor, the air valve consists of an intake valve and an exhaust valve. The intake valve plate is installed on the valve plate of the intake valve and is used to control the gas flow to reduce the pressure in the cylinder. When the compressor is working, when the pressure on both sides of the intake valve plate is different, the intake valve plate will reciprocate relative to the valve plate, causing the air inlet of the valve plate to open or close with the reciprocating motion of the intake valve plate. Now, a convenient valve plate appearance inspection device is needed.

[0003] Existing valve plate appearance inspection devices rely on manual operation, resulting in low efficiency, difficulty in guaranteeing valve plate quality, and an inability to automate production. They also require significant manpower and resources, leading to high production costs and hindering the development of automated valve plate processing. Furthermore, existing valve plate appearance inspection devices have several drawbacks. They require precise valve plate positioning, which is often lacking in current devices, leading to valve plate displacement on the placement table and inaccurate gripping. Manual unloading is also required, as current devices typically lack automatic unloading capabilities, making them inconvenient for users and significantly reducing automation. Finally, the devices fail to properly categorize and store defective and qualified valve plates, rendering them impractical. Utility Model Content

In addition, the appearance inspection device can automatically collect unqualified and qualified valve plates together, making the appearance inspection device more practical in use.

[0014] 1. With a positioning and placement mechanism, the user pulls the limiting plate on the surface of the placement table, causing the limiting plate to slide inside the guide groove. Under the action of the guide groove, the limiting plate is guided and adjusted to the designated position on the surface of the placement table. Then, the user pushes the pull rod downward, causing the pull rod to move the stabilizing suction cup downward until it contacts the inner wall of the guide groove. At this time, the pull rod causes the positioning block to lock into the corresponding fixing plate. Under the action of the stabilizing suction cup, the limiting plate is fixed on the surface of the placement table. Under the action of the limiting plate, the valve plate is limited, realizing the function of limiting the placement of the valve plate by the appearance inspection device. This allows the appearance inspection device to position the valve plate to be inspected on the surface of the placement table during use, avoiding the phenomenon that the valve plate may shift on the surface of the placement table and cause inaccurate gripping of the placement table.

[0015] 2. By setting up an automatic feeding mechanism, the electric push rod inside the fixed cylinder is controlled to work. Under the action of the electric push rod, the moving column moves inside the fixed cylinder, causing the moving column to slide inside the support plate. When the moving column moves, it drives the push plate to move to the surface of the valve plate. Under the combined action of the electric push rod and the push plate, the valve plate after inspection on the surface of the inspection table is pushed out of the inspection table. At this time, qualified valve plates fall into the qualified product collection box, and unqualified valve plates fall into the defective product collection box. The valve plates are classified and stored, realizing the automatic feeding function of the appearance inspection device. This allows the appearance inspection device to automatically feed the valve plates on the surface of the inspection table during use, making the appearance inspection device more convenient for users to operate and greatly improving the degree of automation.

[0016] 3. By incorporating a classification and collection mechanism, after qualified and unqualified valve plates fall into the qualified and unqualified product collection boxes respectively, the user tightens the mounting screws on the surface of the inspection table and then pulls the qualified and unqualified product collection boxes, causing them to move away from the surface of the inspection table. At this time, under the elastic force of the extension spring inside the groove body, the arc-shaped clamp moves away from the surface of the inspection table, thereby removing the qualified and unqualified product collection boxes from the surface of the inspection table. The valve plates inside the qualified and unqualified product collection boxes are then processed. This realizes the function of classifying and storing unqualified and qualified valve plates in the appearance inspection device, making the appearance inspection device more practical to use.

Under the action of the limiting plate 23, the valve plate is limited, so as to realize the function of limiting the placement of the valve plate by the appearance inspection device.

[0029] Furthermore, such as Figure 4 and Figure 7As shown, an automatic feeding mechanism 3 is provided on the surface of the testing table 108. The automatic feeding mechanism 3 includes a support plate 31, a pusher plate 32, and an automatic feeding assembly 33. The automatic feeding assembly 33 is provided on the surface of the testing table 108 and consists of a moving column 331, an electric push rod 332, and a fixed cylinder 333. A support plate 31 is installed on the surface of the top position of the testing table 108. Fixed cylinders 333 are installed on the surface of the support plate 31. The moving column 331 is provided inside the fixed cylinder 333, and one end of the moving column 331 passes through the support plate 31. It extends to the outside of the support plate 31. The moving column 331 slides with the inner wall of the support plate 31. The inner wall of the fixed cylinder 333 is provided with grooves, and the grooves slide with the surface of the moving column 331. An electric push rod 332 is installed inside the fixed cylinder 333. The electric push rod 332 can be of the DG series. The input end of the electric push rod 332 is electrically connected to the output end of the control button 101. The output end of the electric push rod 332 is fixed to the surface of the moving column 331. A pusher plate 32 for pushing materials is installed on the surface of the moving column 331.

[0030] During implementation, the electric push rod 332 inside the fixed cylinder 333 is controlled to work. Under the action of the electric push rod 332, the moving column 331 is driven to move inside the fixed cylinder 333, so that the moving column 331 slides inside the support plate 31. When the moving column 331 moves, the moving column 331 drives the pusher plate 32 to move to the surface of the valve plate. Under the combined action of the electric push rod 332 and the pusher plate 32, the valve plate after inspection on the surface of the inspection table 108 is pushed out of the surface of the inspection table 108. At this time, qualified valve plates fall into the qualified product collection box 107, and unqualified valve plates fall into the defective product collection box 109. The valve plates are classified and stored to realize the automatic feeding function of the appearance inspection device.

[0031] Furthermore, such as Figure 2 and Figure 4As shown, the surfaces of the inspection table 108, the qualified product collection box 107, and the defective product collection box 109 are all equipped with a sorting and collection mechanism 4. The sorting and collection mechanism 4 internally includes an arc-shaped clip 41, mounting screws 42, and a sorting and collection assembly 43. The sorting and collection assembly 43 is disposed on the surfaces of the inspection table 108, the qualified product collection box 107, and the defective product collection box 109, and is composed of a groove body 431 and a extension spring 432. Mounting screws 42 are threadedly connected to the surfaces of the qualified product collection box 107 and the defective product collection box 109. One end of the device passes through the qualified product collection frame 107 and the defective product collection frame 109 respectively and is threadedly fastened to the surface of the inspection table 108. The surfaces of the qualified product collection frame 107 and the defective product collection frame 109 are each provided with a groove body 431. An arc-shaped clip 41 is provided inside the groove body 431. The arc-shaped clip 41 slides and engages with the inner wall of the groove body 431. The arc-shaped clip 41 engages and engages with the surface of the inspection table 108. A tension spring 432 is installed inside the groove body 431. One end of the tension spring 432 is fixed to the surface of the arc-shaped clip 41.

[0032] In practice, after the qualified and unqualified valve plates fall into the qualified product collection box 107 and the defective product collection box 109 respectively, the user tightens the mounting screw 42 on the surface of the inspection table 108 and then pulls the qualified product collection box 107 and the defective product collection box 109, causing them to move away from the surface of the inspection table 108. At this time, under the elastic force of the extension spring 432 inside the groove body 431, the arc-shaped clamp 41 moves away from the surface of the inspection table 108, thereby removing the qualified product collection box 107 and the defective product collection box 109 from the surface of the inspection table 108. The valve plates inside the qualified product collection box 107 and the defective product collection box 109 are then processed to realize the function of the appearance inspection device in classifying and storing unqualified and qualified valve plates.

[0033] Working principle: In use, first place the device housing 1 in the designated position. The user places the valve plate to be tested on the surface of the placement platform 102. The user pulls the limiting plate 23 on the surface of the placement platform 102, causing the limiting plate 23 to slide inside the guide groove 22. Under the action of the guide groove 22, the limiting plate 23 is guided, adjusting it to the designated position on the surface of the placement platform 102. Then, the user pushes the pull rod 24 downwards, causing the pull rod 24 to move the stabilizing suction cup 25 downwards until it contacts the inner wall of the guide groove 22. At this time, the suction cup... Pull rod 24 drives positioning block 26 to lock into the corresponding fixed plate 21. Under the action of stabilizing suction cup 25, limiting plate 23 is fixed on the surface of placement table 102. Under the action of limiting plate 23, valve plate is limited to achieve the function of limiting the placement of valve plate by appearance inspection device. This allows the appearance inspection device to position the valve plate to be inspected on the surface of placement table 102 during use, avoiding the phenomenon that the valve plate is displaced on the surface of placement table 102 during use, which would result in inaccurate gripping of placement table 102.

[0034] Subsequently, the user operates the control button 101, which controls the steering mechanism 105 to work. Under the action of the steering mechanism 105, the detector 103 rotates inside the device housing 1, causing the detector 103 to move above the valve plate, clamp the valve plate and place it on the surface of the detection table 108. Then, the detection results of the valve plate's size and shape are displayed on the surface of the display screen 104. The user can operate the keyboard 106 on the surface of the device housing 1 to adjust the detection speed of the valve plate inside the device housing 1.

[0035] Subsequently, after the surface inspection of the valve plate is completed, the user operates the control button 101, which controls the electric push rod 332 inside the fixed cylinder 333 to work. Under the action of the electric push rod 332, the moving column 331 moves inside the fixed cylinder 333, causing the moving column 331 to slide inside the support plate 31. When the moving column 331 moves, it drives the pusher plate 32 to move to the surface of the valve plate. Under the combined action of the electric push rod 332 and the pusher plate 32, the valve plate after surface inspection of the inspection table 108 is pushed out of the surface of the inspection table 108. At this time, qualified valve plates fall into the qualified product collection box 107, and unqualified valve plates fall into the defective product collection box 109. The valve plates are classified and stored to realize the automatic unloading function of the appearance inspection device. This allows the appearance inspection device to automatically unload the valve plates on the surface of the inspection table 108 during use, making the appearance inspection device more convenient for users to operate and greatly improving the degree of automation.

[0036] Subsequently, after the qualified and unqualified valve pieces fall into the qualified product collection box 107 and the defective product collection box 109 respectively, the user tightens the mounting screws 42 on the surface of the inspection table 108 and then pulls the qualified product collection box 107 and the defective product collection box 109, causing them to move away from the surface of the inspection table 108. At this time, under the elastic force of the extension spring 432 inside the groove body 431, the arc-shaped clamp 41 moves away from the surface of the inspection table 108, thereby removing the qualified product collection box 107 and the defective product collection box 109 from the surface of the inspection table 108. The valve pieces inside the qualified product collection box 107 and the defective product collection box 109 are then processed to realize the function of classifying and storing unqualified and qualified valve pieces by the appearance inspection device. This allows the appearance inspection device to automatically collect unqualified and qualified valve pieces together, making the appearance inspection device more practical in use, and finally completing the use of the valve piece appearance inspection device.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
