[0050] The limiting mechanism 223 includes an abutment plate 2231, which is slidably connected to the horizontal plate surface of the main limiting plate 2213 and the auxiliary limiting plate 2222.

[0053] The principle and advantages of the glass cover coating tooling based on the uniform spraying structure:

[0054] Limitation of glass cover:

[0055] In actual use, the staff controls the feeding assembly 25 and uses the electric slide rail in conjunction with the external telescopic unit to move the glass cover plate to be coated into the fixed frame 21 . By controlling the driving member to drive the driving gear 243 to rotate, the ring gear 241 will rotate at a uniform speed, and the contact arc plate 242 on the ring gear 241 will rotate synchronously with the ring gear 241. When the contact arc plate 242 and the abutment arc block 2215 contact each other, the abutment arc block 2215 will squeeze the main movable rod 2212 to move toward the direction of the glass cover to be coated with the cooperation of the contact arc plate 242. When the main movable rod 2212 moves, the main racks 2216 on both sides thereof respectively drive the transmission gears 2214 on both sides to rotate, and cooperate with the secondary rack 2223 on the secondary movable rod 2221, so that when the main limit plate 2213 is close to the edge of the glass cover, the secondary limit plate 2222 is away from the glass cover, thereby realizing that the two symmetrical main limit plates 2213 in the fixed frame 21 limit and fix the two sides of the glass cover to be coated.

[0056] It is worth noting that the contact arc plate 242 is an outwardly convex arc shape. As the gear ring 241 rotates, the extrusion between the contact arc plate 242 and the abutment arc block 2215 increases (a plurality of rollers are embedded and installed on the outer surface of the circumference of the contact arc plate 242, which can reduce the friction between the abutment arc plate and the abutment arc block 2215 and improve the smoothness of movement between the two), and then the main movable rod 2212 will drive the main limit plate 2213 to complete the limit fixation from the middle of both sides of the glass cover plate. The main limit plate 2213 is set to be L-shaped. When the main limit plate 2213 limits and fixes the glass cover plate, the horizontal plate of the main limit plate 2213 will support the non-coated surface of the glass cover plate, and when the coated surface is not blocked, it is convenient for the coating component 1 to evenly coat the glass cover plate.

[0057] When the coating is completed on the upper surface of the glass cover, the staff drives the fixing frame 211, the fixing frame 21 and the glass cover that has been limited to rotate synchronously and slowly by controlling the external driving unit in the frame 2, and the driving member cooperates with the driving gear 243 to drive the gear ring 241 to rotate in the opposite direction, so that the degree of extrusion between the contact arc plate 242 and the abutting arc block 2215 can be gradually reduced. With the cooperation of the compression spring, the main movable rod 2212 drives the main limiting plate 2213 to gradually separate from the side wall of the glass cover, and cooperates with the main rack 2216, the auxiliary rack 2223 and the transmission gear 2214, so that the auxiliary movable rod 2221 can drive the auxiliary limiting plate 2222 to move toward the side wall of the glass cover. When the main limit plate 2213 has not completely separated from the glass cover plate, and the auxiliary limit plate 2222 has just contacted the glass cover plate, the external telescopic unit in the fixing frame 211 will drive the sliding rod 231 and the supporting block 232 to gradually approach the glass cover plate. In addition, when the other two sides of the glass cover plate enter the placement groove 233, the temporary support of the glass cover plate is completed, which can prevent the glass cover plate from falling when the main limit plate 2213 and the auxiliary limit plate 2222 are switched, causing damage to the glass cover plate.

[0058] When the external driving unit drives the glass cover plate to flip 180 degrees, the uncoated side of the glass cover plate is facing upward, and the auxiliary limiting plate 2222 completes the limiting of the glass cover plate. Since the auxiliary limiting plate 2222 is L-shaped, when the auxiliary limiting plate 2222 limits the glass cover plate, the horizontal plate of the auxiliary limiting plate 2222 will support the coated surface of the glass cover plate, and then the coating part can coat the uncoated side of the glass cover plate.

[0059] It is worth noting that the main limit plate 2213, the secondary limit plate 2222 and the placement groove 233 are all provided with flexible rubber pads on the contact surface with the glass cover plate, and the sum of the lengths of the two secondary limit plates 2222 is the same as the length of the main limit plate 2213, which can ensure that no matter which side is limited, the coverage of the edge of the glass cover plate is consistent, avoiding insufficient support due to size differences, which affects the limit of the glass cover plate. The position of the abutment arc block 2215 and the contact arc plate 242 is staggered with the main movable rod 2212 and the secondary movable rod 2221, and when the main movable rod 2212 or the secondary movable rod 2221 moves, there will be no motion interference between them.

[0060] The present invention adopts the main limiter 221 and the auxiliary limiter 222, which has the following advantages:

[0061] Advantage 1: through the coordinated work of the main limit plate 2213 and the auxiliary limit plate 2222, after the coating on one side of the glass cover is completed, it can be smoothly reversed 180 degrees and then limited again. The auxiliary limit plate 2222 is L-shaped, which supports the coated surface and limits the uncoated surface, making it easy to coat the other side of the glass cover, thus realizing double-sided coating of the glass cover, simplifying the double-sided coating steps of the glass cover, and improving the coating efficiency.

[0062] Advantage two: both the main limit plate 2213 and the auxiliary limit plate 2222 adopt an L-shaped structure, and their horizontal plates only contact the non-coated surface of the glass, while the coated surface is completely exposed, avoiding the obstruction of the coating area by traditional clamps, ensuring that the coating component 1 can evenly cover the entire surface, reducing the problem of uneven film thickness or edge missing. After the glass cover is flipped over, the horizontal plate of the auxiliary limit plate 2222 supports the coated surface, and the uncoated surface is still unobstructed, meeting the needs of double-sided continuous coating.

[0063] Advantage three, when the main limit plate 2213 and the auxiliary limit plate 2222 are switched, the external telescopic unit in the fixed frame 211 drives the sliding rod 231 and the supporting block 232 to approach the glass cover plate, and the other two sides of the glass cover plate enter the placement groove 233 to play a temporary supporting role, thereby avoiding the glass cover plate from falling and causing damage during the switching process between the main limit plate 2213 and the auxiliary limit plate 2222, reducing production costs, and improving production yields. In addition, the main limit plate 2213, the auxiliary limit plate 2222 and the contact surface of the placement groove 233 with the glass cover plate are all provided with flexible rubber pads, which can buffer the pressure on the glass cover plate during limiting, prevent the glass cover plate from cracking and damage due to hard squeezing, and protect the integrity of the glass cover plate.

[0064] Limitation of the main limiting plate 2213 and the auxiliary limiting plate 2222:

[0065] When the main limit plate 2213 contacts the side wall of the glass cover, the contact plate 2231 contacts the side wall of the glass cover. As the distance between the main limit plate 2213 and the glass cover decreases, the contact plate 2231 gradually approaches the vertical plate position of the main limit plate 2213, and the return spring 2233 is compressed. When the contact plate 2231 drives the push plate 2237 to move to a certain distance in the moving rod 2236, the inclined surface of the end of the push plate 2237 contacts the inclined surface of the limit block 2238. As the contact plate 2231 continues to move, the push plate 2237 squeezes the limit block 2238, so that the limit block 2238 extends out of the moving rod 2236 and is engaged in the limit hole 2235 opened on the side wall of the rod sleeve 2234, and the movement of the main movable rod 2212 is hindered, so that the main limit plate 2213 no longer moves toward the glass cover. Similarly, the abutting plate 2231 on the auxiliary movable plate cooperates with the corresponding limiting mechanism 223 to lock the auxiliary limiting plate 2222 .

[0066] It is worth noting that one side of the limiting hole 2235 and the limiting block 2238 is provided with a straight surface, and the other side is chamfered. When the limiting block 2238 enters the limiting hole 2235, the straight surfaces between the two will abut against each other, which can prevent the main movable rod 2212 and the auxiliary movable rod 2221 from continuing to approach the glass cover. The size of the limiting hole 2235 is larger than the limiting block 2238. When the gear ring 241 rotates in the opposite direction and the degree of compression between the contact arc plate 242 and the abutting arc block 2215 is reduced, the compression spring will gradually drive the main movable rod 2212 to gradually reset, and at the same time, the reset spring 2233 sleeved on the outer surface of the circumference of the guide rod 2232 will gradually reset, and then the push plate 2237 will be separated from the limiting block 2238. Under the cooperation of the elastic frame, the limiting block 2238 will retract into the moving rod 2236 to avoid affecting the normal movement of the moving rod 2236 in the rod sleeve 2234.

[0067] The present invention adopts the limiting mechanism 223, which has the following advantages:

[0068] Advantage 1: when the main limit plate 2213 and the auxiliary limit plate 2222 are close to the glass cover, the distance between the abutment plate 2231 and them is reduced. After the inclined surface of the push plate 2237 contacts the inclined surface of the limit block 2238, the limit block 2238 is triggered to extend and fit into the limit hole 2235 of the rod sleeve 2234, forming a mechanical self-locking. This process automatically cuts off the further advancement of the main movable rod 2212 and the auxiliary movable rod 2221, avoiding the main limit plate 2213 and the auxiliary limit plate 2222 from applying excessive pressure on the side wall of the glass cover, avoiding the glass cover from breaking or generating microcracks due to excessive clamping force, ensuring the integrity of the glass cover, and reducing the defective rate during the coating process.

[0069] Advantage 2: Through the coordinated work between the abutment plate 2231, the push plate 2237, the limit block 2238 and the limit hole 2235, the limit force of the main limit plate 2213 and the auxiliary limit plate 2222 on the glass cover can be controlled. When the appropriate limit force is reached, the limit block 2238 is inserted into the limit hole 2235, which can effectively prevent the main movable rod 2212 and the auxiliary movable rod 2221 from continuing to approach the glass cover, ensuring that the glass cover maintains a stable position during the coating process, avoiding the shaking of the glass cover due to insufficient limit force, which affects the coating quality. This stable limit state can ensure that the glass cover is fixed in position during the entire coating process, providing a good foundation for the coating operation and improving the uniformity and consistency of the coating.
