DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0025] The utility model provides a kind of full bonding equipment of liquid crystal display module and backlight module as Figures 1-4 As shown in the figure, it includes fuselage 2 and push rod 5 installed on the inner wall of the upper end of fuselage 2.

[0026] The lower end outer wall of push rod 5 is fixedly connected with heating plate 4.

[0027] The lower side of heating plate 4 is provided with supporting plate 9 to limit the pre-adhesion position of liquid crystal display module and backlight module.

[0028] The lower end outer wall of supporting plate 9 is fixedly connected with movable platform 10, and liquid crystal display module and backlight module are placed on supporting plate 9. Under the design of the supporting plate 9, they will be accurately aligned to the predetermined position. Push rod 5 moves downward through transmission mechanism, so that heating plate 4 contacts liquid crystal display module and backlight module. Heating plate 4 will release heat, so that the adhesive reaches the molten state, thereby improving its fluidity, facilitating full contact with the module. Heating plate 4 presses liquid crystal display module and backlight module together with uniform pressure by controlling downward pressure, ensuring that their adhesive surfaces are in full contact. After heating and pressurizing, keep for a certain period of time, wait for the adhesive to solidify, and after adhesion is completed, push rod 5 returns to the initial position, so that liquid crystal display module and backlight module can be taken out from supporting plate 9.

[0029] The separating groove 13 is arranged between the supporting plate 9 and the movable platform 10, so as to separate the supporting plate 9 and the movable platform 10. In the hot pressing process, the lifting plate same as the supporting plate 9 is used to pre-adhere the liquid crystal display module and the backlight module outside the hot press, so that after the front liquid crystal display module and the backlight module are adhered, the supporting plate 9 can be quickly replaced as the lifting plate of the pre-adhered liquid crystal display module and the backlight module on the movable platform 10, so that the quick replacement is completed, and the idle time of the hot press is reduced.

[0030] As shown in Figure 3 and Figure 4 , the upper end outer wall of the movable platform 10 is internally and respectively close to the front and rear sides of the two sides is provided with a sliding groove 14, the lower end outer wall of the supporting plate 9 is centrally and respectively close to the front and rear sides of the two sides is fixedly connected with a sliding block 16 inserted into the sliding groove 14, the lower end outer wall of the supporting plate 9 is close to the left side and is fixedly connected with a sliding sleeve 15 inserted into the sliding groove 14, the interiors of the two sliding sleeves 15 are provided with sliding rods 17, the upper end inner walls of the two sliding grooves 14 are close to the left side and are provided with upwardly opened clamping grooves 18 for the insertion of the sliding rods 17, and the interiors of the two sliding rods 17 are provided with moving wheels 20 to guide the lateral movement of the supporting plate 9.

[0031] When the operator needs to adjust the original position of the supporting plate 9 or the lifting plate on the movable platform 10, the sliding block 16 at the lower end of the supporting plate 9 is inserted into the sliding groove 14 and is laterally moved, the sliding block 16 at the lower end of the supporting plate 9 or the lifting plate is moved in the sliding groove 14, and due to the cooperation of the moving wheels 20, the lateral movement of the supporting plate 9 or the lifting plate becomes light and stable. When the sliding rod 17 in the sliding sleeve 15 at the lower end of the supporting plate 9 or the lifting plate passes through the clamping groove 18, the sliding rod 17 in the sliding sleeve 15 falls into the clamping groove 18, and the moving wheel 20 contacts and collides with the bottom end of the clamping groove 18, and a sound is emitted. After hearing the collision sound, it means that the position of the supporting plate 9 or the lifting plate is slid in place, and the subsequent movement can be performed.

[0032] As shown in Figure 2 and Figure 4 , the upper end outer walls of the two sliding rods 17 are fixedly connected with limiting plates 19 to limit the maximum sliding distance of the sliding rods 17, and the upper end outer walls of the movable platform 10 are respectively close to the left and right sides and are provided with recesses 12.

[0033] When the sliding rod 17 falls into the clamping groove 18, the maximum falling distance of the sliding rod 17 can be limited by the limiting plate 19, so that the sliding rod 17 cannot be pulled out of the sliding sleeve 15. When the supporting plate 9 is removed, the left and right sides of the supporting plate 9 or the lifting plate can be gripped through the recess 12, so that the supporting plate 9 and the movable platform 10 can be separated.

[0034] As shown in Figure 1As shown, the front end of the outer wall of the fuselage 2 is provided with a plurality of operation knobs a6 near the right side, which are respectively emergency stop button and temperature size adjustment knob, the front end of the outer wall of the fuselage 2 is provided with a plurality of operation knobs b7 near the right side, which are respectively heating switch and positive pressure adjustment knob, the left end of the outer wall of the fuselage 2 is inlaid with a display screen 8 near the left side.

[0035] The emergency stop button in the operation knob a6 is to immediately stop all operations of the equipment. No matter the running state of the equipment, pressing the emergency stop button will cut off the power of the machine, ensuring the safety of operation, the temperature size adjustment knob is to control the working temperature of the heating plate 4. The operator can adjust the appropriate temperature according to the material properties of the liquid crystal display module and backlight module used, to ensure the best curing effect of the adhesive, the heating switch in the operation knob b7 is used to start or close the heating function, by controlling the opening and closing of the heating system, the positive pressure adjustment knob adjusts the positive pressure in the hot press to control the bonding strength of the liquid crystal display module and the backlight module, the display screen 8 displays important operation information such as current temperature, equipment state, pressure value and progress bar in the hot pressing process.

[0036] As shown in Figure 1 The lower end of the outer wall of the fuselage 2 is fixedly connected with a base 1, a plurality of guide rods 3 are fixedly connected between the upper end of the outer wall of the base 1 and the lower end of the inner wall of the fuselage 2 at equal intervals, to limit the up and down movement direction of the heating plate 4, and guide rails 11 are fixedly connected to the upper end of the outer wall of the base 1 and respectively near the left and right sides, to guide the movement of the movable platform 10.

[0037] During the hot pressing process, the push rod 5 moves downward to push the heating plate 4 to vertically descend under the limitation of the guide rod 3, ensuring that the contact surface of the heating plate 4 is uniform, when the hot pressing operation is performed, the movable platform 10 drives the supporting plate 9 to the outside of the fuselage 2 under the guidance of the guide rail 11, at this time, the worker can take out the bonded liquid crystal display module and backlight module, and pre-bond the liquid crystal display module and backlight module in the supporting plate 9, after pre-bonding, the supporting plate 9 is conveyed to the lower side of the heating plate 4 by the movable platform 10, waiting for bonding.

[0038] The principle of the embodiment is that the liquid crystal display module and the backlight module are placed on the supporting plate 9, and under the design of the supporting plate 9, they are accurately aligned to the predetermined position. The push rod 5 is moved downward through the transmission mechanism, so that the heating plate 4 contacts the liquid crystal display module and the backlight module. The heating plate 4 releases heat, so that the adhesive reaches a molten state, thereby improving the fluidity and facilitating sufficient contact with the module. The heating plate 4 controls the downward pressure, so that the liquid crystal display module and the backlight module are pressed together with uniform pressure, so as to ensure that the adhesive surfaces are in sufficient contact. After heating and pressurizing, a certain time is kept, and the adhesive is solidified. After the adhesion is completed, the push rod 5 returns to the initial position, and the liquid crystal display module and the backlight module can be taken out from the supporting plate 9. During the hot pressing process, the same lifting plate as the supporting plate 9 can be used outside the hot press, and the liquid crystal display module and the backlight module are pre-adhered, so that after the front liquid crystal display module and the backlight module are adhered, the supporting plate 9 can be quickly replaced by the lifting plate for loading the pre-adhered liquid crystal display module and the backlight module on the movable platform 10, thereby completing the quick replacement, and reducing the idle time of the hot press.
