Detailed Implementation

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] like Figure 1 As shown, an embodiment of this application discloses a waterproof edge grinding inspection machine, including a frame 1. A transport platform 2 arranged along the Y-axis is provided inside the frame 1. A front suction component 3 and a rear suction component 4 that move along the transport platform 2 are provided on the transport platform 2. A first grinding device 5, a first AOI inspection mechanism 6, a second grinding device 7 and a second AOI inspection mechanism are provided on one side of the transport platform 2 on the frame 1.

[0032] Both the front suction component 3 and the rear suction component 4 include a base plate 301. An opening and closing module 302 is provided on the base plate 301. A first suction component 303 and a second suction component 304 are provided on the driving end of the opening and closing module 302. A rotation positioning mechanism is provided on the base plate 301.

[0033] Both the first suction assembly 303 and the second suction assembly 304 include a suction cup body 305 and a first vacuum pipe connected to the suction cup body 305, and also include a first filter 306. The first filter 306 includes an inlet end, an outlet end, a positive pressure end, and a drain end. The inlet end of the first filter 306 is connected to a vacuum generator through a second vacuum pipe, and the positive pressure end of the first filter 306 is connected to a compressed air generator through a third vacuum pipe. A drain pipe is provided at the drain outlet of the first filter 306, and a pneumatic control valve 307 is provided on the drain pipe. The control end of the pneumatic control valve 307 is sequentially connected to a fourth solenoid valve 308 and a compressed air generator. A second solenoid valve 309 is provided on the first vacuum pipe, a first solenoid valve 310 is provided on the second vacuum pipe, and a third solenoid valve 311 is provided on the third vacuum pipe.

[0034] Specifically, it should be explained that when the first grinding device and the second grinding device 7 are working, water spraying operation will be performed on one side of the first grinding device and the second grinding device 7.

[0035] In actual operation, after the front suction component 3 picks up the product, it is driven by the transport platform 2 and transported to the first grinding device 5 for grinding on both sides. After grinding, the product is inspected by the first AOI inspection mechanism 6. Then, the external robot grabs the product, rotates it 90 degrees, and places it on the rear suction component 4. Driven by the transport platform 2, the product is transported to the second grinding device for grinding on the other two sides. After grinding, the product is inspected by the second AOI inspection mechanism.

[0036] The specific product suction steps of the front suction component 3 and the rear suction component 4 are as follows: the vacuum pressure is adjusted by the pressure regulating valve 314, the first solenoid valve 310 and the second solenoid valve 309 are opened, and vacuum is drawn through the first vacuum pipe and the second vacuum pipe. The suction cup body 305 works and adsorbs the product. After water splashes into the first vacuum pipe, the water flows back into the first filter 306 and is stored. The suction cup body 305 stops working, the first solenoid valve 310 and the second solenoid valve 309 are closed, and the third solenoid valve 311 and the fourth solenoid valve 308 are opened, so that the positive pressure air path control air control valve 307 is opened. The positive pressure air path drains the water in the first filter 306 through the third vacuum pipe.

[0037] The design of the vacuum suction pipeline in this structure allows water vapor to be promptly discharged from the vacuum pipeline even if it enters, thereby reducing damage to components and extending the lifespan of the entire suction assembly.

[0038] In this embodiment, a fourth vacuum pipe is provided between the first solenoid valve 310 and the first filter 306, a pressure gauge sensor 312 is provided at the end of the fourth vacuum pipe, and a second vacuum filter 313 is provided on the fourth vacuum pipe.

[0039] Specifically, when vacuum adsorption of products, the fourth vacuum pipe is connected to the main vacuum line to detect and read the current vacuum pressure value, thereby ensuring that the vacuum pressure during product adsorption is within a suitable range.

[0040] In this embodiment, both the first AOI inspection mechanism 6 and the second AOI inspection mechanism include an upper waterproof cover 601 and a lower waterproof cover 602. An upper AOI inspection camera is disposed inside the upper waterproof cover 601, and a lower AOI inspection camera is disposed inside the lower waterproof cover 602. A notch for the upper AOI inspection camera to take pictures is provided on the bottom surface of the upper waterproof cover 601, and a first transparent glass is disposed at the notch. A notch for the lower AOI inspection camera to take pictures is provided on the upper surface of the lower waterproof cover 602, and a second transparent glass is disposed at the notch. An air knife structure 603 for removing water stains from the first transparent glass, the transparent glass, or the product is provided on one side of the first transparent glass and the second transparent glass.

[0041] Specifically, under the action of the transport platform 2, the adsorbed products will pass through the first AOI inspection agency 6 and the second AOI inspection agency in sequence for AOI inspection, so that defective products can be removed or reprocessed in the future.

[0042] In this structure, by setting an upper waterproof cover 601 and a lower waterproof cover 602 in the first AOI inspection mechanism 6 and the second AOI inspection mechanism, the upper AOI inspection camera and the lower AOI inspection camera can be waterproofed, thereby ensuring the operation of the upper AOI inspection camera and the lower AOI inspection camera.

[0043] In this embodiment, a first waterproof cable routing pipe 604 for cable routing is provided on one side of both the upper and lower protective water covers, and a wet exhaust port 605 for connecting to an external air extraction device is provided on one side of both the upper and lower protective water covers.

[0044] Specifically, the first waterproof cable conduit 604 can protect cables and other connecting wires, thus ensuring waterproof protection for the cables. At the same time, the wet exhaust port 605 can be connected to an external air extraction device, so that even if moisture enters the upper waterproof cover 601 and the lower waterproof cover 602, the external air extraction device can be used to extract the air, thereby ensuring the dryness of the upper waterproof cover 601 and the lower waterproof cover 602, and thus ensuring that the upper AOI inspection camera and the lower AOI inspection camera can work in a dry environment.

[0045] In this embodiment, both the first grinding device and the second grinding device are provided with an air blowing device 51 at the front end of the material inlet. The air blowing device 51 includes an air blowing waterproof housing 511. An air blowing pipe 513 that can extend out of the air blowing waterproof housing 511 is provided inside the air blowing waterproof housing 511. The air inlet end of the air blowing pipe 513 is located inside the waterproof housing. A second waterproof wiring pipe 512 is provided at the top of the air blowing waterproof housing 511. A manual calibration slide 514 is provided inside the air blowing waterproof housing 511. The upper end of the air blowing pipe 513 is mounted on the manual calibration slide 514.

[0046] Specifically, under the action of the transport platform 2, the adsorbed products will pass through the first grinding device and the second grinding device in sequence. Before entering the first grinding device or the second grinding device, they will first pass through the blowing device 51 to remove dust or moisture from the surface.

[0047] In this structure, only the air blowing end of the air blowing pipe 513 extends out of the waterproof housing, which can protect the upper end of the air blowing pipe 513 and the connecting cable. At the same time, the setting of the manual calibration slide 514 can correct the position of the air blowing pipe 513, thereby achieving a better cleaning effect.

[0048] In this embodiment, a cover plate 21 is provided on the upper surface of the transport platform 2, and the cover plate 21 has an inverted V-shaped structure.

[0049] Specifically, when water droplets fall onto the cover plate 21 during grinding, the V-shaped structure of the cover plate 21 causes the water droplets to slide down the slope of the cover plate 21 to the bottom of the frame 1, thus preventing water droplets from accumulating on the cover plate 21 and falling into the transport platform 2 through the gaps in the cover plate 21. Therefore, the V-shaped cover plate 21 can effectively provide waterproof protection for the transport platform 2.

[0050] In this embodiment, a Y-axis drag chain protective frame 22 for placing the Y-axis drag chain is provided on one side of the transport platform 2. Both the cover plate 21 and the Y-axis drag chain protective frame 22 are made of waterproof material, and a waterproof connector 23 is provided on one side of the Y-axis drag chain protective frame 22.

[0051] Specifically, the Y-axis cable chain protective frame 22 can protect the Y-axis cable chain, thereby providing waterproof protection.

[0052] In this embodiment, the base plate 301 is an arc-shaped plate structure, which includes an upper plate and a drive plate located between the transport platform 2 and the cover plate 21. The upper plate and the lower plate are connected by a bending part, and the two ends of the cover plate 21 are connected to the transport platform 2 through side plates.

[0053] Specifically, in this structure, the combined action of the bow-shaped plate structure, the cover plate 21 and the side plate can keep the internal drive structure of the transport platform 2 in a sealed environment, thereby reducing the entry of water vapor into the interior of the transport platform 2 and ensuring the normal operation of the transport platform 2.

[0054] In this embodiment, the rotary positioning mechanism includes a lifting module, a DD motor 801 is provided on the driving end of the lifting module, an adsorption mechanism 802 is provided on the driving end of the DD motor 801, a waterproof cover plate 803 is provided on the extended end of the driving rod of the DD motor 801, and a waterproof sealing ring is provided at the connection between the waterproof cover plate 803 and the DD motor 801.

[0055] Specifically, the adsorption mechanism 802 can be used to adsorb products, and the waterproof cover plate 803, in conjunction with the waterproof sealing ring, can seal the internal control structure of the DD motor 801, thereby preventing moisture from entering the internal control structure of the DD motor 801 and causing the components of the DD motor 801 to rust or be damaged.

[0056] This invention also discloses a waterproof edge grinding inspection machine method, including the waterproof edge grinding inspection machine described above. After the suction component picks up the product, under the drive of the transport platform 2, the product is transported sequentially to the first grinding device 5 for grinding operations on both sides. After grinding, the product is inspected by the first AOI inspection mechanism 6. Then, the external robot arm grabs the product, rotates it 90 degrees, and places it on the rear suction component 4. Under the drive of the transport platform 2, the product is transported sequentially to the second grinding device for grinding operations on the other two sides. After grinding, the product is inspected by the second AOI inspection mechanism.

[0057] The specific product suction steps of the front suction component 3 and the rear suction component 4 are as follows: the vacuum pressure is adjusted by the pressure regulating valve 314, the first solenoid valve 310 and the second solenoid valve 309 are opened, and vacuum is drawn through the first vacuum pipe and the second vacuum pipe. The suction cup body 305 works and adsorbs the product. After water splashes into the first vacuum pipe, the water flows back into the first filter 306 and is stored. The suction cup body 305 stops working, the first solenoid valve 310 and the second solenoid valve 309 are closed, and the third solenoid valve 311 and the fourth solenoid valve 308 are opened, so that the positive pressure air path control air control valve 307 is opened. The positive pressure air path drains the water in the first filter 306 through the third vacuum pipe.

[0058] This method, through the design of the vacuum suction pipeline, ensures that even if water vapor enters the vacuum pipeline, it can be promptly discharged from the vacuum pipeline, thereby reducing damage to components and improving the lifespan of the entire suction assembly.

[0059] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of the present invention. It should be understood that the above descriptions are merely specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
