There are also two pressing plates 2415 in the mechanism corresponding to the slide connection part. They are installed on different sides of the synchronous belt respectively, and can drive the sliding plate 2412 to open and close under the drive of the synchronous belt's forward and reverse rotation.

[0057] Movement process of the rotary transfer assembly 2000

[0058] When a cleaning basket assembly is output in the nine-slot cleaning machine, the X-axis transfer assembly 2200 is driven to drive the Y-axis transfer assembly 2300 and the transfer gripper assembly 2400 to move above the cleaning basket, and then the grab hook 2413 is opened to the maximum state under the drive of the motor in the transfer gripper assembly 2400, and then the Y-axis transfer assembly 2300 moves downward so that the grab hook 2413 in the transfer gripper assembly 2400 is on both sides of the cleaning basket, and then the transfer gripper assembly 2400 is The motor drive in the synchronous belt drives the grab hook 2413 to shrink to the position of tightly grasping the cleaning basket, and then successfully grasps the cleaning basket assembly. Since it is convenient to take materials from the cleaning basket in the subsequent links, the cleaning basket output from the nine-slot cleaning machine must be rotated 90 degrees and placed on the subsequent conveyor line. Therefore, when placing it, the X-axis transfer assembly 2200 is driven to drive the Y-axis transfer assembly 2300 and the transfer gripper assembly 2400 to move above the conveyor line. At this time, the rotating cylinder in the transfer gripper assembly 2400 rotates 90 degrees, and then the cleaning basket assembly is placed on the cleaning basket chain plate conveyor assembly 3000.

[0113] The movement process of the micro-lifting positioning mechanism 4100:

[0114] The object of transmission and positioning of the micro-lifting and positioning mechanism 4100 is the cleaning rack. When the cleaning rack is transported to the top of the mechanism under the detection of photoelectricity, the blocking part 4D starts to block first, and the initial state of the positioning cylinder 4111 is the cylinder diameter extension state. After the cleaning rack is blocked and transported, under the drive of the positioning cylinder 4111, the positioning block 4113 clamps the cleaning rack, and then the lifting cylinder 4114 lifts the cleaning rack to make it leave the chain plate conveyor line. The cleaning rack is full of mobile phone glass. When the robot grabs the glass, it is fixed relative to the chain plate conveyor assembly 4200. Therefore, in order to take out all the mobile phone glass in the cleaning rack, the cleaning rack needs to be micro-moved to ensure that there is glass every time the robot grabs the glass. At this time, the cleaning rack as a whole moves slowly under the drive of the micro-movement driving part 4B until the glass in the cleaning rack is taken out. After taking out the glass in the cleaning rack, the lifting cylinder 4114, the positioning cylinder 4111 and the blocking cylinder 4121 are restored, and the empty cleaning rack is transported to the end of the conveyor.

[0130] The roller conveyor assembly 7000 is composed of a roller conveyor 7100, a centering and aligning mechanism 7200 and an end stop 7300. The layout of each part is as follows: Fig.43 shown.

[0131] Roller conveyor 7100 structure Fig.44 As shown in the figure, a conveyor specially designed for conveying mobile phone glass to avoid scratches and edge collapse. As shown in the figure below, a servo motor drives a synchronous belt to drive the roller shaft fixed with PEEK material to rotate and transmit the mobile phone glass forward. The PEEK roller can effectively protect the mobile phone glass. In order to ensure that the mobile phone glass is evenly conveyed forward and meet the equipment's demand for glass conveying, the conveyor is designed as a left-right symmetrical roller conveyor with two identical parts, and a single conveyor is driven in sections by two servo motors. This can avoid the deformation of the roller shaft caused by the excessive width of a single conveyor, making the glass conveying more stable.

[0132] The structure of the centering and aligning mechanism 7200 is shown in Figure 45. There are two sets in the roller conveyor assembly 7000, which are installed on the profile frame of the roller conveyor 7100 by screws. It consists of a bottom mounting drive part 7201, an upper sliding part 7202 and an alignment stud 7203. Due to its simple structure, it will not be described separately.

[0135] The alignment stud 7203 is made of PEEK material and is installed on the slide plate in the upper sliding part 7202 through a threaded connection in order to prevent damage to the glass when clamping the glass.

[0136] The principle of the centering and alignment mechanism is that the servo motor drives the synchronous belt transmission with the linear slide rail as the guide, driving the upper sliding part 7202 of the two parts to realize the clamping action. In this way, when the mobile phone glass is transported to the end block 7300 position, the glass is aligned under the clamping action of the above-mentioned drive and alignment stud 7203 to ensure the accuracy of the position when the No. 2 robot component 9000 grabs and places the glass.

[0137] End stop structure 7300 in Fig.46As shown, due to the simple structure, no single part will be described.

[0228] 10000 pallet loading and unloading assembly movement process

[0229] The tray loading and unloading assembly 10000 is installed at the output port of the rear frame 1200 by screws, and this part is directly connected to the rear PVD coating machine. The tray assembly loading split belt part C and split lead screw part D are initially in an open state. The cover transfer part F is initially in the state that the entire transfer gripper is located in the middle of the split belt, and the cylinder in the cover transfer part F is in a retracted state.

[0230] The working principle is that the PVD coating machine outputs the tray assembly (the tray below, with a cover on the tray), directly outputs it to the roller of the tray assembly unloading and conveying roller part B in the tray loading and unloading assembly 10000, and then continues to be conveyed forward to the rib 10212 of the tray assembly unloading and conveying roller part B. At this time, the photoelectric given tray assembly loading part E tray assembly in place signal, the module in the tray assembly loading part E drives the tray assembly to rise to a position higher than the conveyor belt position in the tray assembly loading split belt part C, at this time the split screw part D drives the lead screw and then drives the tray assembly feeding split belt part C to the retracted state, and then the tray assembly feeding part E moves down to place the tray assembly on the conveyor belt of the tray assembly feeding split belt part C. At this time, the conveyor belt conveys the tray assembly forward and conveys it to the buffer pad mounting plate 10316. After being transported to the position, the photoelectric signal is transmitted to the cover plate transfer part F to extend its cylinder, and the suction cup absorbs the cover plate. Then the cylinder in the cover plate transfer part F retracts, and the cover plate is completely moved out of the top of the tray under the action of the transfer module 10602. So that the mobile phone glass can be grabbed and placed on the tray. When the tray is full of mobile phone glass, the cover plate needs to be transferred back to the tray full of glass, and then the tray assembly feeding split belt part C reverses and outputs the entire tray assembly full of glass to the PVD coating machine. In this way, the loading and unloading of a tray assembly is completed.

[0231] Working principle of the whole machine:

[0232] At the beginning, the nine-slot cleaning machine outputs the cleaned cleaning basket assembly (the cleaning basket is equipped with a cleaning rack, and the cleaning rack is filled with cleaned mobile phone glasses), the rotating transfer assembly 2000 grabs the cleaning basket assembly and places it on the cleaning basket chain plate conveyor assembly 3000, the cleaning basket chain plate conveyor assembly 3000 conveys the cleaning basket assembly to the transplanting assembly 5000, the transplanting assembly 5000 grabs the cleaning rack from the cleaning basket and places it on the cleaning rack conveyor assembly 4000, and the empty cleaning basket is then reversely transported to the other end of the chain plate conveyor, that is, the working area of ​​another set of transplanting assemblies 5000. The cleaning rack conveyor assembly 4000 conveys the cleaning rack assembly to its micro-motion lifting and positioning mechanism 4100. When the micro-motion lifting and positioning mechanism 4100 drives the cleaning rack to micro-move, the robot assembly No. 1 8000 repeatedly takes out the upright glass from the cleaning rack and places it flat on the roller conveyor assembly 7000 along the same path until all the glass in the cleaning rack is taken out. The cleaning rack continues to be conveyed to the end of the cleaning rack chain conveyor, that is, the working area of ​​the transfer assembly 5000. At this time, the transfer assembly 5000 grabs the empty cleaning basket and places it in the empty cleaning rack in the cleaning basket chain conveyor assembly 3000. The empty cleaning basket assembly is manually removed or directly transferred to the cache conveyor 6000 for cache. When the glass is placed on the roller conveyor assembly 7000, it is transported to the grabbing position of the No. 2 robot assembly 9000, and is grabbed onto the pallet of the pallet loading and unloading assembly 10000. The pallet assembly of the pallet loading and unloading assembly 10000 is transported from the pallet conveying port of the PVD coating machine. When the pallet is full, the cover plate transfer module in the pallet loading and unloading assembly 10000 covers the pallet, and then transports the full pallet to the PVD coating machine to complete the production process of this process. The workflow of the above-mentioned whole machine is shown in Figure 1, which is also the workflow when the equipment is operating normally.

[0233] When the equipment fails or is under maintenance, it should not affect the cleaning or PVD coating of the glass. At this time, the above-mentioned working process of the equipment may be involved in manual processing. At this time, the working principle of the equipment begins with the nine-slot cleaning machine outputting the cleaned cleaning basket assembly (the cleaning basket is equipped with a cleaning rack, and the cleaning rack is full of cleaned mobile phone glass), the rotating transfer assembly 2000 grabs the cleaning basket assembly and places it on the cleaning basket chain plate conveyor assembly 3000, the cleaning basket chain plate conveyor assembly 3000 reversely conveys the cleaning basket assembly to the transfer assembly 5000 (to transfer the empty cleaning basket assembly), and the transfer assembly 5000 directly transfers it to the buffer conveyor 6000 for manual processing.

[0234] The above embodiments are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements of the present invention by relevant technical personnel in the field should be extended to the protection scope determined by the claims of the present invention.
