[0001] This utility model relates to the field of glass processing equipment technology, specifically to a flipping mechanism and a glass slab balancing machine. Background Technology

[0002] Currently, the production process of mobile phone glass includes: engineering drawing, material cutting, fine carving, flat grinding / polishing, ultrasonic cleaning, tempering, ultrasonic cleaning, screen printing / drying, QC, packaging and shipping to the screen assembly bonding process.

[0003] Currently, before screen printing, cleaned glass needs to be placed on a tray and then enter the screen printing process. However, the glass is still placed manually, which not only makes the glass prone to scratches and dirt, but also reduces the glass yield and efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a flipping mechanism and a glass arranging machine to solve the problems mentioned in the background art.

[0005] By adopting the above technical solution, the problems of scratches and dirt caused by manual placement of glass for screen printing are solved, thus improving efficiency and yield. To solve the above technical problems, this utility model provides the following technical solution:

[0006] A flipping mechanism and a tray-stacking machine include a frame. Two sets of tray-lifting devices and conveying equipment are provided on the top of one side of the frame, and a rotating rack turntable is provided on the other side. The tray-lifting devices are equipped with an electric cylinder lifting platform and a horizontal telescopic cylinder, and the electric cylinder lifting platform and the horizontal telescopic cylinder are located on the side of the conveying equipment that are far away from each other. A front-to-back moving module is fixedly installed at the rear end of the frame, and a lateral moving module is slidably installed on the outer side of the front-to-back moving module. A flipping connecting mechanism is fixedly connected to the front end of the lateral moving module.

[0007] Preferably, the bottom of the frame is uniformly and rotatably equipped with casters, and the bottom of the frame is rotatably equipped with support feet via threads.

[0008] Preferably, the top of the rotating insert turntable is provided with four sets of glass picking stations for the cleaning rack, and the top of each glass picking station is provided with two side plates of the glass cleaning rack. Glass racks of the glass cleaning rack are evenly fixedly installed on the top of the two side plates of the glass cleaning rack.

[0009] Preferably, a front push cylinder is fixedly installed at the middle position of the top of the frame, and the output end of the front push cylinder is located on one side of the glass rack of the glass cleaning rack.

[0010] Preferably, a flipping manipulator is rotatably mounted on the other side of the flipping vacuum nozzle module, and a 90-degree rotation servo motor that is fixedly connected to the flipping manipulator is fixedly mounted on the front end of the flipping vacuum nozzle module.

[0011] Preferably, the flipping mechanism includes any one of the above 1-5, wherein a miniature position compensation servo motor is fixedly installed at the front and rear ends inside the flipping manipulator, and a lead screw is fixedly connected to the output end of the miniature position compensation servo motor. A fixing plate is installed on the outside of the lead screw through a threaded connection, and a vacuum suction cup is uniformly fixedly installed on the other side of the fixing plate.

[0012] Compared with existing technologies, this utility model uses a conveyor and lifting platform to transport the pallet to the robot arm placement position. The robot arm moves to the turntable cleaning rack position, and then the Z-axis module drives the flipping connection mechanism to pick up the glass from the cleaning rack. The rotary servo motor drives the suction nozzle module to flip downwards by 90 degrees, making it vertical. Then, the micro servo motor drives the lead screw to rotate to compensate for the suction nozzle position. Then, the glass is picked up by the vacuum suction cup. The Z-axis module pulls the glass upwards and flips it to a horizontal state through the flipping connection mechanism to make the glass flat. The robot arm moves to the conveyor belt pallet position, and the Z-axis descends so that the glass can be automatically placed in the screen printing pallet in sequence and the pallets can be automatically stacked together. It can pick up three to four pieces of glass from the cleaning rack at the same time, and can process about 4,500 pieces per hour. This replaces the manual placement of glass to be screen printed, while improving the glass screen printing yield, reducing scratches, and increasing efficiency. Attached Figure Description

[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] As described in the background section, there are shortcomings in the existing technology. In order to solve the above-mentioned technical problems, this application proposes a flipping mechanism and a glass slab arranging machine.

[0018] Please see Figures 1-2 A flipping mechanism and glass arranging machine include a frame 1. Two sets of stacking tray lifting devices 2 and a conveying device are provided on the top of one side of the frame 1, and a rotating material picking platform 4 is provided on the other side. The stacking tray lifting device 2 is provided with an electric cylinder lifting platform 201 and a horizontal telescopic cylinder 202. The electric cylinder lifting platform 201 and the horizontal telescopic cylinder 202 are located on the side of the conveying device that are far away from each other. A front and rear moving belt module 3 is fixedly installed at the rear end of the frame 1. A transverse moving module 301 is slidably installed on the outside of the front and rear moving belt module 3. A flipping vacuum suction nozzle module 5 is fixedly connected to the front end of the transverse moving module 301.

[0019] With the above-described structural configuration, this flipping mechanism and glass tray placement machine places stacked screen printing trays filled with glass sheets onto the tray lifting device 2 at the inlet end of the conveyor. The horizontal telescopic cylinder 202 of the tray lifting device 2 at the inlet end extends, separating the bottom tray from the second-to-last tray. The conveyor moves to transport the separated trays to the middle, where the empty screen printing trays await glass sheet placement. The electric cylinder lifting platform of the tray lifting device at the outlet end rises to support the stacked trays, the horizontal telescopic cylinder retracts, and the electric cylinder lifting platform descends to lift the trays and place them on the pins of the horizontal telescopic cylinder. The two electric cylinder lifting platforms function as tray loading and unloading mechanisms. The conveyor then transports the screen printing trays to the placement position via the forward and backward moving belt module 3. 01 drives the rotating vacuum suction nozzle module 5 to rotate and adsorb the glass, then rotates it again to a horizontal position. Subsequently, the moving belt module 301 moves the glass to place it into the tray. The automatic glass tray machine can use a robotic arm to vacuum pick up one to four cleaned glass pieces to be screen printed on the turntable platform cleaning rack, and place them into the trays on the conveyor. The glass tray speed is 3 times faster than manual placement (the tray machine can handle about 4,500 pieces per hour). The clean glass to be screen printed reduces screen printing defects caused by manual placement, improves placement efficiency, improves the yield of glass products, and solves the problems of reduced glass yield and efficiency, scratches and dirt on glass caused by manual placement. It also facilitates the next process of screen printing.

[0020] Furthermore, casters 101 are evenly rotatably mounted on the bottom of the frame 1, and support feet 102 are rotatably mounted on the bottom of the frame 1 via threads. The casters 101 facilitate the movement of the frame 1 to the work position, and the support feet 102 are rotated to suspend the casters 101 in the air, thereby stably placing the frame 1 in the designated position.

[0021] Furthermore, the top of the rotary material handling platform 4 is provided with four sets of glass picking stations 401 for the cleaning rack, and the top of the glass picking station 401 is provided with a glass cleaning rack baffle 402. The glass rack rack glass rack rack rack rack rack rack racks 403 are evenly fixedly installed on the top of the two side plates 402 of the glass cleaning rack rack. The front push cylinder 404 is fixedly installed in the middle position of the top of the frame 1, and the output end of the front push cylinder 404 is located on one side of the side plate 403. First, the glass rack 403 of the glass cleaning rack is pushed by the front-pushing cylinder 404. The glass cleaning rack baffle 402 fixes one end of the glass, so that the cleaning rack is placed on the upper part of the glass picking station 401, waiting for the robot vacuum nozzle to pick up the material. Then, the flip vacuum nozzle module 5 is moved to the top of the glass rack 403 of the glass cleaning rack by the front-back moving belt module 301. At this time, the flip vacuum nozzle module 5 is in a vertical state. After the flip vacuum nozzle module 5 adsorbs the glass sheet, it is moved to the rear end by the front-back moving belt module 301 and the glass is placed on the top of the tray to wait for the next process.

[0022] Furthermore, including the flipping plate mechanism, a flipping manipulator 501 is rotatably mounted on the other side of the flipping connection mechanism 5, a 90-degree rotation servo motor 502 is fixedly mounted on the front end of the flipping vacuum nozzle module 5 and fixedly connected to the flipping manipulator 501, a micro-compensation servo motor 503 is fixedly mounted on the front and rear ends inside the flipping manipulator 501, and a lead screw 504 is fixedly connected to the output end of the micro-compensation servo motor 503. A fixing plate 505 is installed on the outside of the lead screw 504 through a threaded connection, and a vacuum suction cup 506 is evenly fixedly mounted on the other side of the fixing plate 505. In this process, the glass to be picked up is rotated to the picking station below the flipping robot 501 via the turntable platform. Then, the flipping vacuum nozzle module 5 moves the flipping robot 501 to the top of the tray. The 90-degree rotation servo motor 502 drives the flipping robot 501 to rotate downwards by 90 degrees. At this time, the vacuum suction cup 506 is in a vertical position. The micro compensation servo motor 503 drives the lead screw 504 to rotate, so that the vacuum suction cup 506 can automatically perform position compensation and micro-adjustment. Then, the vacuum suction cup 506 picks up the glass, and the 90-degree rotation servo motor 502 rotates it 90 degrees to make the vacuum suction cup 506... The glass is horizontally adsorbed, making it easy to place on the conveyor screen printing platform for the next process. The flipping vacuum nozzle module 5 drives the flipping robot arm 501 to descend, allowing the glass to be automatically and sequentially placed in the screen printing tray and the trays to be automatically stacked together. The robot arm can simultaneously pick up 1 to 4 pieces from the cleaning rack (output of 4000-5000 pieces / hour) and place them directly in the tray without intermediate correction or positioning. It does not come into contact with any object, so it will not cause scratches or dirt, saving labor and improving product yield and glass tray placement efficiency, thus laying a supply guarantee for the next glass screen printing process.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
