The first step is that, as shown in figure 1, the product is placed, the display screen backboard module is placed on the jig board to ensure that the display screen backboard module is not damaged when the display screen backboard module is processed on the production line, and then the jig board and the display screen backboard module are placed on the multiple chain conveyor line 1 together for conveying, and are processed through a series of equipment;
The second step is to attach the adhesive tape on the periphery of the frame of the back plate module of the display screen, as shown in figure 3, the adhesive tape can limit the adhesive tape range, the adhesive tape dispenser 3 can only carry out adhesive tape dispensing within the adhesive tape attaching range, the adhesive tape is ensured not to overflow to other parts outside the frame of the back plate, the adhesive tape attaching process is manually completed by operators as auxiliary work, the adhesive tape attaching platform 2 is a working area of the operators, the jig plate moving on the multiple chain conveying line 1 and the back plate module of the display screen are temporarily transferred to the working areas of the operators on two sides, the specific working principle is that firstly, the first cylinder 25 pushes the adhesive tape attaching platform 2 to move on a long rail 23 arranged on the bottom plate 22, the frame carries the roller line working platform to be close to the multiple chain conveying line 1, the roller and the multiple chain conveying line 1 are in butt joint, thus the display screen products can be manually transferred from the multiple chain conveying line 1 to the roller line working platform, then the first cylinder 25 is controlled to retract, the operators carry the jig plate and the roller line working platform to the positions on the multiple chain conveying line 1, the operators can drive the multiple chain conveying line 1 to the multiple chain conveying line 1 again, and the multiple chain conveying line 1 can be driven to rotate the multiple chain conveying line 1 again, and the multiple chain conveying device can be driven to work time-consuming time, and the multiple chain conveying device can be completed, and the multiple chain conveying device can be driven to work and the multiple chain conveying line 1 to be time and the multiple chain conveying device can be completed to be time and the multiple-prolonged, and the multiple chain conveying device can be time and the time-consuming machine and time can and time.
The third step is to glue the back plate module of the display screen, as shown in figure 5, after the back plate module of the display screen is attached with the adhesive tape, the adhesive tape needs to be glued, and the working principle of the glue dispenser 3 is that after the back plate module of the display screen is moved to the glue dispensing platform 31 of the glue dispenser 3, the limiting mechanism 14 on the glue dispensing platform 31 can prevent the back plate of the display screen from continuing to move forwards, then the glue dispensing pipe 32 above the glue dispensing platform 31 can move under the drive of the three-axis transmission mechanism (the effect of the three-axis transmission mechanism is to drive the glue dispensing pipe 32 to move in the front and back directions of the X axis, the left and right directions of the Y axis and the up and down directions of the Z axis, belonging to the prior art), the glue dispensing is carried out on each part on the back plate module of the display screen, and meanwhile, in order to adapt to the display screens with different sizes, the self-adaptive width adjusting guide mechanism 33 is also arranged on the glue dispenser 3.
In the fourth step, glue scraping is performed, as shown in fig. 7, after the display screen backboard module is subjected to glue scraping, glue on the surface needs to be scraped uniformly, and the working principle of the glue scraping machine 4 is that when the display screen module subjected to glue scraping is moved onto the glue scraping platform 41 of the glue scraping machine 4, the limiting mechanism 14 on the glue scraping platform 41 can prevent the display screen backboard from continuously moving forwards, the cross beam 42 moves forwards and backwards on the left linear track and the right linear track, the glue scraping plate 43 is scraped on the display screen (the cross beam 42 moves on the linear track and is matched with a driving motor and a traditional ball screw mechanism, the specific principle is not specifically described), and meanwhile, glue is spread on the left side and the right side of the glue scraping plate 43 when the glue scraping is performed, so that glue receiving grooves are formed in the glue scraping platform 41 and are used for receiving the glue spreading, the glue drops on the glue spreading devices, the left side and the right side end of the glue receiving grooves 44 can be prevented from damaging the devices, and when the cross beam 42 moves to the tail ends of the two linear tracks, the glue receiving grooves can be directly connected with the whole glue receiving device 45, and the glue receiving device can be adjusted, and the glue receiving device can be used for receiving the glue dropping from the tail ends when the tail ends of the glue receiving device is well, and the glue receiving device can be used for receiving the glue receiving the whole device 45, and the glue receiving from the position and the device.
In the fifth step, glue is heated and aged, as shown in fig. 10, after the glue on the surface of the display screen backboard module is scraped uniformly, as the glue is the glue, the glue is solidified for a longer time, so that when the display screen backboard module and the liquid crystal display screen module are attached, the glue easily flows into the liquid crystal display screen to damage the product, and the fixing effect is not obvious, so that the glue needs to be heated and dried, the glue on the surface of the display screen backboard module is heated and aged by using the glue aging equipment on the assembly line, the solidification speed of the glue is accelerated, the glue aging equipment works in the principle that as a plurality of glue aging mechanisms are arranged together, when the display screen backboard module moves to the first group of glue aging mechanisms, the clamping mechanism moves downwards to clamp the display screen product from the multiple chain conveyor line 1, then moves to the heating platform 51 on two sides through the parallel guide rails 52 for glue heating and aging, meanwhile, the display screen product on the back is not stopped for a longer time, but moves to the second group of glue aging mechanisms for glue aging, and so on, the glue aging can be realized, and the display screen products are heated simultaneously, the glue aging is carried out by the glue aging equipment, and the glue aging mechanism is carried out after the glue aging mechanism is continuously, the glue is carried out by the multiple times after the glue is clamped by the left and the glue is placed on the back to the display screen module for 5 minutes.
