[0024] It should be noted that, when performing the film pasting operation, the liquid crystal display module is firstly transported to the first loading station 111 and the second loading station 112 respectively by the transport robot 300, so as to realize the automatic loading operation; then, the first moving module 110 is started, and the liquid crystal display module on the first loading station 111 is driven to the first film pasting station 113, at which time the first moving module 110 stops moving, and the first film pasting module 120 on one side is started, and the film pasting operation is performed on the liquid crystal display module on the first film pasting station 113 by the first film pasting module 120, and after the film pasting operation is completed, the first moving module 110 is started again, and the liquid crystal display module on the first loading station 111 is driven to the first film pasting station 113 by the first moving module 110 The LCD display module 20 that has completed the film pasting operation is transferred to the second unloading station 212 to wait for unloading.

In addition, since the utility model realizes automatic loading, automatic unloading and automatic film pasting operations of the LCD display module, it can improve production efficiency compared to the traditional single-station film pasting device. In addition, it reduces manual interference and can also improve film pasting accuracy. Preferably, the structure of the first film laminating module 120 is the same as that of the second film laminating module 220. Similarly, the structure of the first transfer module 110 is the same as that of the second transfer module 210.

The sliding table is connected to the linear motor module, and the sliding table is driven by the linear motor module to perform linear displacement, so that the liquid crystal display module can move between different first workstations.

[0025] In one embodiment, the automatic film pasting structure 10 for liquid crystal display modules further includes a first conveyor belt 400, which is located between the first film pasting device 100 and the second film pasting device 200. The first conveyor belt 400 is used to transfer the liquid crystal display module 20 to the bottom of the handling robot 300. That is, the first conveyor belt 400 continuously transfers the liquid crystal display module 20 to the bottom of the handling robot 300, so that the handling robot 300 grabs the liquid crystal display module on the first conveyor belt 400 to the first loading station 110 and the second loading station 210. In this way, automatic loading operation can be achieved, manual intervention can be reduced, and production efficiency can be improved. In this embodiment, the first conveyor belt 400 can be a belt conveyor.

[0026] Furthermore, the automatic film pasting operation 10 of the liquid crystal display module also includes a second conveyor belt 500, which is located between the first film pasting device 100 and the second film pasting device 200, and the second conveyor belt 500 is used to transfer the liquid crystal display module 20 to the next station.

In this way, the automatic unloading operation can be realized to reduce manual intervention, thereby improving production efficiency. In this embodiment, the second conveyor belt 500 can be a belt conveyor.

[0027] In one embodiment, the first film laminating module 120 includes a first material discharging workbench 121, a first material discharging structure 122 and a first film laminating robot 123. The first material discharging structure 122 is located on a side of the first material discharging workbench 121. The protective film material belt on the first material discharging structure 122 extends to the first material discharging structure 122, so that the first film laminating robot 123 located on the first material discharging workbench 121 can remove the protective film monomer on the first material discharging structure 122, and the first film laminating robot 123 is also used to attach the protective film monomer to the surface of the liquid crystal display module 20 placed on the first film laminating station 113.

[0028] It should be noted that a material unwinding tensioning mechanism is provided on the first unwinding workbench 121, and the protective film coil is always kept in a tensioned state during the unwinding process through the material unwinding tensioning mechanism, and the first unwinding structure is used to store the protective film coil and continuously unwind the protective film coil. In this embodiment, the first unwinding structure is a prior art and is not described in detail here. Furthermore, the protective film monomer on the protective film coil is removed by the first film-laminating robot 123 and attached to the surface of the liquid crystal display module 20 on the first film-laminating station 113, thereby realizing automatic film-laminating operation.

[0029] Furthermore, the first film laminating robot 123 includes a first driving component and a first vacuum adsorption component 123a. The first vacuum adsorption component 123a is located above the first material discharge workbench 121. The first driving component is connected to the first vacuum adsorption component 123a. The first driving component is used to drive the first vacuum adsorption component 123a to reciprocate between the first material discharge workbench 121 and the first film laminating station 130.

[0030] It should be noted that the protective film monomer is adsorbed and fixed by the first vacuum adsorbent 123, so that the protective film monomer is separated from the release film on the protective film roll, and then the first vacuum adsorbent 123 is driven by the first driving member to move toward the first film laminating station 130, and the protective film monomer is aligned with the liquid crystal display module on the first film laminating station 130 and the film laminating operation is performed. In addition, the use of vacuum adsorption to transport the liquid crystal display module can prevent the liquid crystal display module from being damaged, thereby ensuring the appearance quality of the liquid crystal display module.

[0031] Further, the first vacuum adsorption member 123a includes a first mounting frame 123a1, a first vacuum adsorption plate 123a2 and a first attachment roller 123a3, the first mounting frame 123a1 is connected to the first driving member, the first vacuum adsorption plate 123a2 is arranged on the first mounting frame 123a1, and the first attachment roller 123a3 is arranged on the side surface of the first vacuum adsorption plate 123a2 facing the liquid crystal display module 20. Among them, the first vacuum adsorption plate 123a2 is used to adsorb and fix the protective film monomer. When the protective film monomer is aligned with the surface of the liquid crystal display module on the first film-attaching station 130, the first vacuum adsorption plate 123a2 releases the protective film monomer, and the first attachment roller 123a3 rolls over the surface of the protective film monomer, so that the protective film monomer is attached to the surface of the liquid crystal display module, and the bubbles are squeezed out at the same time to ensure the quality of film attachment. In this embodiment, preferably, the first driving member is a linear motor module.

[0032] Furthermore, the first film laminating device 100 further includes a shooting alignment module 600, which is located above the first film laminating station 130. That is, the shooting alignment module 600 is a CCD camera, which shoots the position of the liquid crystal display module 20 on the first film laminating station 130 through the CCD camera, and transmits the shooting data to the terminal control device, and compares it with the original data of the protective film and makes compensation adjustments to ensure that the protective film monomer can be aligned with the surface of the liquid crystal display module 20 during the film laminating operation. Similarly, a shooting alignment module 600 is also provided above the second film laminating station 230 to ensure the precise alignment and lamination of the protective film monomer and the liquid crystal display module.

[0033] In one embodiment, the handling robot 300 includes a linear motor module, a first sliding adsorption frame 310 and a second sliding adsorption frame 320. The first sliding adsorption frame 310 and the second sliding adsorption frame 320 are respectively connected to the linear motor module, and the linear motor module is used to drive the first sliding adsorption frame 310 and the second sliding adsorption frame 320 to perform linear motion.

[0034] It should be noted that the purpose of setting the first sliding adsorption frame 310 and the second sliding adsorption frame 320 is to facilitate the alternating loading and unloading operations of the first film pasting device 100 and the second film pasting device 20. In this embodiment, the linear motor module can use the existing dual-drive linear motor module to separately control the first sliding adsorption frame 310 and the second sliding adsorption frame 320 to alternately realize the loading and unloading of double stations, or two single-drive linear motor modules can be used to control the first sliding adsorption frame 310 and the second sliding adsorption frame 320 respectively. Specifically, in this embodiment, the first sliding adsorption frame 310 and the second sliding adsorption frame 320 have the same structure, and only the first sliding adsorption frame 310 is described here. Two adsorption areas are respectively arranged on the first sliding adsorption rack 310, including a loading adsorption area and a unloading adsorption area, that is, the loading adsorption area adsorbs and fixes the LCD module that has not yet been film-applied, and the unloading adsorption area adsorbs and fixes the LCD module that has completed the film-applied operation. Since the first loading station and the second loading station are located at different positions, in order to avoid the need for the handling robot 300 to add other actions, two adsorption areas are directly arranged on the same first sliding adsorption rack 310 to meet the loading and unloading requirements. Further, in this embodiment, since the placement positions of the LCD modules on the first conveyor belt and the second conveyor belt are different from the placement positions of the LCD modules on the first film-applied device and the second film-applied device, a rotary drive structure is arranged on both the first sliding adsorption rack 310 and the second sliding adsorption rack 320, and the rotary drive structure drives the first sliding adsorption rack 310 and the second sliding adsorption rack 320 to rotate, so that the LCD module reaches the preset position requirements in different areas, for example, the rotary drive structure adopts an existing rotary cylinder. Furthermore, in this embodiment, a lifting module is also connected to the linear motor module, and the lifting module drives the linear motor module to perform lifting movement, so that the first sliding adsorption frame 310 and the second sliding adsorption frame 320 can achieve lifting movement. For example, the lifting module can also use a linear motor module to achieve lifting operation.

[0035] It should also be noted that since the loading adsorption area and the unloading adsorption area are designed as an integrated whole, after the first sliding adsorption rack 310 transports the unfilmed LCD display module on the first conveyor belt to the first transfer module 110, it can then transport the LCD display module on the first unloading station 112 that has completed the film-laminating operation to the second conveyor belt when returning, and so on, over and over again, thereby reducing waiting time and improving work efficiency.

[0036] The working process of the automatic film-attaching structure of the liquid crystal display module in one embodiment is as follows:

[0037] 1. The liquid crystal display module is transported by the first conveyor belt 400 and flows under the transport robot 300. When the infrared sensor head at the end of the first conveyor belt 400 senses the liquid crystal display module, the first conveyor belt 400 stops;

[0038] 2. The first sliding adsorption rack 310 and the second sliding adsorption rack 320 work alternately to grab the liquid crystal display module on the first conveyor belt 400 and rotate it to a preset angle, and then place it at the first loading station 111 and the second loading station 211 respectively.

[0039] 3. The liquid crystal display modules on the first loading station 111 and the second loading station 211 are transferred to the first film attaching station 113 and the second film attaching station 213 by the first transfer module 110 and the second transfer module 210 respectively.

[0040] 4. The shooting and alignment modules above the first film-sticking station 113 and the second film-sticking station 213 respectively shoot the position of the liquid crystal display module, and the acquired data is compared with the original data of the protective film and then compensated and adjusted to ensure the accuracy of the film-sticking position.

[0041] 5. After the shooting and alignment are completed, the first film pasting module 120 and the second film pasting module 220 respectively perform film pasting operations on the liquid crystal display modules on the first film pasting station 113 and the second film pasting station 213 .

[0042] 6. After the film laminating operation is completed, the first transfer module 110 and the second transfer module 210 transfer the liquid crystal display module to the first unloading station 112 and the second unloading station 212 respectively to wait for unloading.

[0043] 7. The transport robot 300 is started again, and the first sliding adsorption rack 310 and the second sliding adsorption rack 320 respectively transport the liquid crystal display module that has completed the film-laminating operation to the second conveyor belt, thereby completing the unloading operation.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
