The positioning fixture 2 has a positioning plate, a reference block, two positioning slide blocks and a driver, the reference block is fixed on the positioning plate, and the driver drives the positioning slide blocks to slide along the X and Y directions respectively to clamp the product together with the reference block.

[0040] See also Figure 2 , Figure 4 and Figure 5 , the number of the storage bins 31 is multiple, and they are arranged in a row along the horizontal direction. The picking device 3 also includes a frame 33, the storage bins 31 are vertically mounted on the frame 33 and can slide relative to the frame 33, and there is a film taking space 3a between the lower part of the storage bin 31 and the conveying device 7, so that the picking robot 32 can slide from the lower part of the storage bin 31 and enter the target storage bin 31 to take the film. By making the storage bins 31 slidable, non-target storage bins can be close together, thereby reducing the occupied space or using more storage bins 31 to store more protective films. In addition, the two sides of each storage bin 31 can be divided into a plurality of separated compartments 311, and the compartments 311 are a structure with one side open. One compartment 311 can be used to store one type of protective film. Therefore, the storage bins 31 can store protective films corresponding to the models of almost all electronic products on the market today.

[0041] Please see again Figure 4 and Figure 5The picking device 3 further includes a toggle mechanism 34, which is used to push aside part of the storage bins 31 to facilitate the picking robot 32 to take the film. The toggle mechanism 34 is arranged above the frame 33 and above the storage bins 31. Specifically, the toggle mechanism 34 includes a linear driver 341, a telescope 342 and a toggle block 343. The linear driver 341 is arranged on the frame 33 and above the storage bins 31. The telescope 342 is fixed to the output end of the linear driver 341. The output end of the telescope 342 is connected to the toggle block 343 to drive the toggle block 343 to extend into or out of the gap between two adjacent storage bins 31. By setting the linear drive 341, the shifting block 343 can reach the top of any storage bin 31, and then by using the telescopic device 342, the shifting block 343 can be extended between two adjacent storage bins 31 to shift a part of the storage bin 31, so that the target storage bin 31 can have a space for the retrieval manipulator 32 to enter, so that the retrieval manipulator 32 can smoothly take the film. More specifically, the linear drive 341 includes a motor 341a, a screw rod 341b and a slider 341c, the screw rod 341b is pivotally connected to the frame 33, and the central axis extends along the arrangement direction of the storage bins 31, the output end of the motor 341a is connected to one end of the screw rod 341b, the slider 341c slides relative to the frame 33 and is threadedly connected to the screw rod 341b, and the telescopic device 342 is arranged on the slider 341c.

[0043] In addition, the pickup device 3 may also be provided with another toggle mechanism (not shown in the figure), which may be provided on the pickup manipulator 32 and move with the pickup manipulator 32. When the pickup manipulator 32 moves to the bottom of the target storage bin 31, the toggle mechanism may extend into the narrow gap between the target storage bin 31 and the storage bin 31 adjacent thereto, and then push the storage bin 31 adjacent thereto to move it away from the target storage bin 31 by a certain distance, so that the pickup manipulator 32 can enter.

[0044] Please see again Figures 1 to 3 The defoaming device 5 includes a sealed cavity 51, an air pressure system and a lifting mechanism 52. The sealed cavity 51 is used to accommodate the product. The lifting mechanism 52 is arranged on the platform 1 and the output end is connected to the sealed cavity 51.

The air pressure system is connected to the inside of the sealed cavity 51 to provide positive pressure or negative pressure to the sealed cavity 51. By placing the product in the sealed cavity 51 and then pressurizing or evacuating the sealed cavity 51 using the air pressure system, the bubbles in the protective film can be removed, effectively improving the film sticking effect.

[0045] Please see again Figures 1 to 3 , the cleaning device 6 includes at least one rotatable cleaning roller 61, and the present embodiment includes two cleaning rollers 61 arranged side by side. The cleaning roller 61 is arranged above the conveying track of the conveying device 7 and is driven to rotate by a motor. A cleaning cloth or cleaning sponge is provided on the cleaning roller 61. By arranging the cleaning roller 61, the product can pass through the cleaning roller 61 under the automatic transmission of the conveying device 7, thereby realizing automatic cleaning. The cleaning device 6 also includes a vacuum cleaner 62 arranged near the cleaning roller 61. The vacuum cleaner 62 can suck away excessive dust accumulated on the cleaning roller 61, thereby ensuring that the product will not be contaminated again.

[0046] The automatic film laminating machine 100 further includes a film tearing device 101, which is used to tear off the outer film on the surface of the protective film before laminating. The film tearing device 101 is arranged on the platform 1. When the protective film has an outer film, the outer film can be torn off by the film tearing device 101. The film tearing device 101 is a clamp that can clamp the outer film on the surface of the protective film. At the same time, the film laminating robot 4 sucks the protective film, and then the film laminating robot 4 drives the protective film away from the film tearing device 101, so that the outer film is torn off the protective film.

[0047] In summary and in combination with the above drawings, the working principle of the automatic film laminating machine 100 of the present invention is described in detail below:

[0048] Taking a mobile phone as an example, when a film needs to be applied to the screen of the mobile phone, the mobile phone is placed on the positioning plate, and then the mobile phone model is input on the control panel of the film applying machine. The mobile phone model can also be automatically detected by the film applying machine. After that, the control system of the film applying machine controls the driver to drive the positioning slider 341c to move, thereby pushing the mobile phone to move in the direction of the reference block until the reference block and the positioning slider 341c clamp the mobile phone. At this time, the driving mechanism of the conveying device 7 drives the positioning fixture 2 to slide along the guide track 71 and slide to the bottom of the cleaning device 6. The cleaning roller 61 rotates, and the conveying device 7 drives the positioning fixture 2 to pass through the cleaning roller 61, and the cleaning roller 61 automatically wipes the surface of the mobile phone clean. At the same time, the control system determines the position of the protective film of the corresponding model according to the model of the mobile phone, and then controls the linear driver 341 to start, so that it drives the telescopic device 342 to translate to the top of the storage bin 31 corresponding to the position, and then the telescopic device 342 drives the shifting block 343 to extend between the two adjacent storage bins 31, and then the linear driver 341 starts to drive the telescopic device 342 and the shifting block 343 again, so that the shifting block 343 shifts the two storage bins 31 to a certain gap. Then control the pick-up manipulator 32. The X-direction translation mechanism 321, the Y-direction translation mechanism 322, and the Z-direction translation mechanism 323 of the pick-up manipulator 32 work together, and then the suction cup 325 enters the film taking space 3a below the storage bin 31 into the gap of the target storage bin 31, and reaches the position of the protective film of the corresponding model, and then the negative pressure device generates negative pressure on the suction cup 325 to suck up a piece of protective film. Finally, the pick-up manipulator 32 takes out the protective film. At this time, the film sticking robot 4 is started, and the film sticking robot 4 sucks the protective film from the picking robot 32, and then sends it to the film tearing device 101. The film tearing device 101 clamps the outer film on the surface of the protective film. Then the film sticking robot 4 continues to suck the protective film and moves away from the film tearing device 101, so that the outer film peels off the protective film.

[0049] When the cleaning device 6 has finished cleaning the mobile phone, the conveying device 7 drives the positioning fixture 2 to the vicinity of the film sticking manipulator 4. At this time, the control system can obtain the film sticking position of the mobile phone according to the reference position of the reference block, thereby controlling the film sticking manipulator 4 to move and stick the protective film on the mobile phone. When the film sticking is completed, the conveying device 7 conveys the positioning fixture 2 to the bottom of the defoaming device 5. At this time, the lifting mechanism 52 drives the sealed cavity 51 to descend and seals on the positioning fixture 2 to place the mobile phone in the sealed cavity 51. At this time, the air pressure system pressurizes or evacuates the sealed cavity 51. The present invention adopts the form of pressurization, so as to use high pressure to remove the bubbles in the protective film. When the defoaming operation is completed, the conveying device 7 conveys the positioning fixture 2 to the initial position, and the driver drives the positioning slider 341c away from the reference block, thereby releasing the mobile phone, and the mobile phone can be taken out at this time.

[0050] Compared with the prior art, the present invention stores protective films of various specifications in a storage bin 31, uses a positioning fixture 2 to position the product, uses a picking robot 32 to take out the protective film corresponding to the product specifications in the storage bin 31, and then provides a film sticking robot 4, through which the protective film is stuck on the surface of the product, thereby realizing automatic film sticking on the product and improving the film sticking efficiency; and the product on the positioning fixture 2 is conveyed to the debubbling device 5 by the conveying device 7 for debubbling, thereby ensuring that the bubbles between the protective film and the product are effectively removed, greatly improving the film sticking effect.

[0051] like Figures 6 to 8 As shown, the figure shows the structure of the second embodiment of the taking device of the automatic film sticking machine of the present invention.

[0052] The platform 1, positioning fixture 2, film laminating robot 4, defoaming device 5, cleaning device 6 and conveying device 7 of the automatic film laminating machine of this embodiment are the same in structure, function and operation mode as those of the first embodiment, and the difference lies in the structure of the pickup device. Specifically, the pickup device 8 of this embodiment includes a plurality of storage bins 81 and a pickup robot 82, and the plurality of storage bins 81 are fixedly arranged in a stacked manner along the vertical direction, and one side of the storage bins 81 has a film taking space for the pickup robot 32 to move, and there is a gap 811 between two adjacent storage bins 81 for the pickup robot 82 to enter. By arranging the storage bins 81 in a stacked manner, the occupied space can be reduced or more storage bins 81 can be used to store more protective films. The picking robot 82 includes an X-axis translation mechanism 821, a Y-axis translation mechanism 822, a main arm 823, a secondary arm 824, a first motor 825, a second motor 826, a fixed plate 827, a suction cup 828 and a negative pressure device.

The X-axis translation mechanism 821 can drive the suction cup 828 to move in the horizontal direction; the Y-axis translation mechanism 822 can drive the suction cup 828 to move in the vertical direction to the height of the target storage bin 81, and the main arm 823 and the auxiliary arm 824 can drive the suction cup 828 to enter the target position of the storage bin 81, thereby being able to absorb the protective film at any position in the storage bin 81.

[0053] When taking the film, the X-direction translation mechanism 821 and the Y-direction translation mechanism 822 drive the main arm 823 to reach the horizontal height of the target storage bin 81, and then the first motor 825 drives the main arm 823 to swing, thereby driving the auxiliary arm 824 to enter the gap 811 above the target storage bin 81. Then the second motor 825 drives the auxiliary arm 824 to swing, thereby driving the suction cup 828 to approach the top of the storage bin storing the protective film of this type, and then the Y-direction translation mechanism 822 drives the main arm 823 and the auxiliary arm 824 to move downward so that the suction cup 828 is close to the protective film, and then the negative pressure device is activated so that the suction cup 828 sucks the protective film, and then the protective film is moved out of the storage bin 81 through the coordinated work of the X-direction translation mechanism 821, the Y-direction translation mechanism 822, the main arm 823, the auxiliary arm 824, the first motor 825, and the second motor 826.

[0056] When taking the film, the Y-direction translation mechanism 922 raises the X-direction translation mechanism 921 to the highest position, so that the Z-direction translation mechanism 923 is located above the storage bin 91, that is, in the moving space 912, and then the X-direction translation mechanism 921 drives the Z-direction translation mechanism 923 to move to the gap 911 between the target storage bin 91 and the storage bin 91 adjacent thereto, at which time the Y-direction translation mechanism 922 drives the Z-direction translation mechanism 923 to descend, so that it enters the gap 911 and reaches the same level as the protective film of the model. The Z-direction translation mechanism 923 drives the slide plate 924 to translate and align with the protective film, and then the negative pressure device is activated to make the suction cup 925 suck the protective film, and then the protective film is moved out of the storage bin 91 through the operation of the X-direction translation mechanism 921, the Y-direction translation mechanism 922 and the Z-direction translation mechanism 923.

[0057] The circuit structure and control principle of the control system involved in the automatic film laminating machine of the present invention are well known to ordinary technicians in the field and will not be described in detail here.

[0058] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
