Description

Technical Field

[0001] The present invention relates to the field of glass cover plate processing, and particularly to an automatic cover plate laminating machine. Background Art

[0002] In the existing processing and production of glass cover plates, the degree of automation is low. The lamination of glass cover plates is generally manually completed by operators. Due to the different levels of proficiency of on-site operators, there is a large gap in the lamination rate of cover plates. The operating forces and working habits of the operators for cover plate lamination are different. Therefore, it is easy to cause scratches and knocks on the glass, and the cover plates are not laminated tightly, etc. It is very difficult to ensure the quality and yield of products. Moreover, the degree of automation of manual operation is low, and the speed of manually pressing the cover plates is slow and the efficiency is low. In order to meet the market demand, manufacturers need a large number of operators, and the labor cost is high, which increases the production cost of glass manufacturing to a certain extent;

[0003] Most of the existing positioning fixtures use the expansion and contraction of cylinders to drive the separation and proximity of two clamping structures connected above them, so as to achieve the purpose of positioning. However, the stroke of the cylinder is limited and it cannot be applied to mobile phone glasses of various sizes, with great limitations; A single cylinder expansion and contraction positioning device cannot be commonly used for the automatic positioning of glasses at multiple stations on a rotary dividing disk. It can only fixedly position the mobile phone glass placed at one station. During the processing and production process, if it is necessary to position the products at multiple stations on the rotary dividing disk, multiple cylinder expansion and contraction positioning devices need to be set on the rotary dividing disk, making the structure of the equipment more complex and redundant;

[0004] When using multiple cylinder expansion and contraction positioning devices to position multiple stations on the rotary dividing disk, its repeated positioning accuracy is not high, and the positioning errors of different stations are different. The increase in uncertain factors makes the equipment need to be debugged for errors many times during the processing and production process, greatly reducing the production efficiency and processing accuracy, and the yield of products cannot be guaranteed either.

[0019] As can be seen from the above, the beneficial effects of applying the technical solution of the present invention are as follows:

[0020] First, the feeding lifting unit drives the cover plate in the cassette unit to move up and down; the synchronous transfer device drives the suction unit to slide left and right; the primary positioning unit serves as a carrier for positioning; the suction unit is used to adsorb the cover plate and realize the movement and grasping of the cover plate; the cassette unit is used to store the cover plate; the first cylinder is connected to the suction unit to drive the suction unit to realize the function of moving up and down; the floating joint is used to connect the lifting unit and the secondary positioning unit to make them move together; the synchronous motion mechanism drives the positioning mechanism to be tightened and relaxed; the positioning mechanism positions the glass placed in the suction cup jig; the rotary indexing table rotates the positioned product to the next station; the suction cup jig is used to place the glass and the cover plate and perform pressing on it.

[0021] Second, the motor drives the lifting slider to move up and down. Since the jacking rod is arranged on the lifting slider and moves up and down accordingly, the jacking rod will push out the cover plate in the storage chamber of the cartridge unit for the suction unit to adsorb; the transfer module drives the suction unit to move left and right; the four-jaw cylinder has more accurate positioning, making the cover plate fit more tightly; the vacuum suction cup does not damage the workpiece and is pollution-free; the cartridge is convenient for storing and placing the silica gel cover plate, without frequent feeding, saving time. When the cartridge is empty, it is more convenient to directly replace the cartridge and there is no need to stop the machine to add the silica gel cover plate;

[0022] Third, the synchronous motion mechanism is connected to the positioning mechanism through an L-shaped connecting block. When the motor rotates forward and backward, the synchronous pulley rotates forward and backward, driving the synchronous belt to move, and making the positioning unit tense or relax, realizing the precise positioning of the glass cover plate; the slider connecting block is connected to the slider on the slide rail. During the positioning process of the glass cover plate by the cam follower, the cam follower can effectively reduce the impact load on the glass, reduce the occurrence of problems such as glass chipping and scratching, and improve the precision and yield of the product.

[0023] Third, the lifting and tensioning of the cam follower enable the glass to be precisely positioned on the suction jig of the rotary dividing plate; the flange plate connects the divider to the rotary dividing plate to achieve intermittent motion. The divider has the characteristics of high indexing accuracy, stable operation, large transmission torque, self-locking during positioning, compact structure, small volume, low noise, good high-speed performance, and long service life; the gear is used to increase or decrease the motor speed.

[0024] Fourth, the middle part of the frame is set as a double-layer structure, which is convenient for fixing and supporting the feeding system, positioning system and pressing unit, making the structure clear and distinct; among them, the feeding, primary positioning, secondary positioning and pressing processes are all on the upper layer, which is convenient for observation and use.

[0025] In summary, the automatic cover plate laminating machine of the present invention has low cost, high yield, fast efficiency, high degree of automation, is applicable to various sizes, has high positioning accuracy, small limitations, and can work at multiple stations simultaneously.

[0062] Working principle of the present invention: During feeding, the operator loads the cassette 262, and then places the product to be laminated on the suction cup jig 333 and starts the switch. At this time, the solenoid valve opens. First, the automatic positioning of the glass is carried out. Through the lifting, tensioning of the secondary positioning unit 32 and the fine adjustment of the cam follower 328, the glass is accurately positioned on the suction cup jig 333. After the positioning is completed, the vacuum is turned on to suck the product, and the positioning is completed. The motor drives the lifting rod 223 to rise. The first vacuum suction cup 251 of the suction unit 25 sucks the silica gel cover plate from the cassette 262, and then the synchronous transfer device 23 drives the first vacuum suction cup 251 to move above the primary positioning unit 24. The lifting rod 223 descends, places the silica gel cover plate on the second positioning plate 244, and then the positioning cylinder 243 positions the silica gel cover plate. The lifting rod 223 rises and returns to the origin. Then the first vacuum suction cup 251 of the suction unit 25 sucks the silica gel cover plate from the cassette 262, and at the same time the second vacuum suction cup 251 sucks the silica gel cover plate from the primary positioning unit 24. Then the synchronous transfer device 23 drives the first vacuum suction cup 251 to move above the primary positioning unit 24, and at the same time the second vacuum suction cup 251 is above the rotary indexing unit 33. The lifting rod 223 descends. Among them, the silica gel cover plate placed on the second positioning plate 244 is positioned by the positioning cylinder 243, and the silica gel cover plate placed on the suction cup jig 333 is also positioned after being adjusted by the positioning mechanism 323. The lifting rod 223 rises, and the synchronous transfer device 23 returns to the origin. In this way, the positioning and feeding actions are completed by repeating the process.

[0063] After the lamination of the silica gel cover plate and the glass in the rotary indexing unit 33 is completed, the product rotates to align with the pressing unit 4. The pressing cylinder 44 descends to perform pressing, so that the glass and the silica gel cover plate are closely laminated. After the pressing is completed, the rotary indexing disk 331 rotates back to the loading and unloading position. When the photoelectric switch next to the pressing station senses different signals, different solenoid valves are closed, so that the vacuum break of the suction cup jig 333 at the loading and unloading stations is closed, and the laminated glass is unloaded manually or by a robot hand and placed back into the Tray tray. In this way, the cycle is repeated.

[0064] To sum up, the automatic cover laminating machine of the present invention has the advantages of low cost, high yield, fast efficiency, high automation degree, applicability to various sizes, high positioning accuracy, small limitations, and can work at multiple stations simultaneously.
