Description

Technical Field

[0001] The invention relates to a high-precision protective film pasting device with CCD visual detection, belonging to the technical field of film pasting. Background Art

[0002] From a functional perspective, protective film is intended to form an outer protective layer for the physical object being protected. Therefore, some products require protective film lamination after production. Protective film raw materials are usually composed of a backing paper and a film body. Currently, there are two main lamination methods:

[0003] Manual lamination: Operators must first peel the protective film from the backing paper, then manually place and laminate it onto the product surface. This method is not only time-consuming, but also highly susceptible to contamination or damage during operation, seriously affecting lamination quality and production efficiency.

[0004] Mechanical lamination: The machine uses an adsorption device to separate the protective film from the backing paper, then transfers it to the top of the product positioned by a jig, and finally presses it down to complete the lamination. However, when the product requires high dimensional accuracy of the protective film, and the protective film and product dimensions are similar, the mechanical adsorption and separation process often causes problems such as misalignment and tilting, resulting in positional deviation of the protective film subsequently applied, thereby reducing the lamination effect and the quality of the finished product.

[0050] The four support rods 31 connected to the upper end of the bottom box 1 at the other ends are respectively installed on the four corner positions of the lower end of the fixed part of the X-axis driver 32. The four support rods 31 are used in conjunction with each other to lift the X-axis driver 32, and the X-axis driver 32 is located on the rear side of the mounting plate 4.

The product is positioned and placed by the jig 12.

[0052] When in use, first install the rolled protective film material on the feeder 5, and then wind the active part of the rolled protective film material onto the lower outer end of the bidirectional screw rod 6, pass through the first mounting frame 8, wind around the lower outer end of the first guide wheel 41, wind around the left end of the film stripping frame 9, wind around the lower outer end of the fourth guide wheel 96, wind around the right outer end of the third guide wheel 93, wind around the left outer end of the second guide wheel 42, pass between the rotating roller 76 and the auxiliary roller 77, and then put the active part of the rolled protective film material onto the waste collector 7;

[0053] Then the stepper motor 72 is started to drive the first shaft 74 to rotate, thereby rotating the second pulley 73. Since the second pulley 73 is connected to the first pulley 71 by a belt, the rotation of the second pulley 73 will rotate the first pulley 71, thereby rotating the waste collector 7, thereby rewinding the protective film base paper, thereby applying traction to the protective film raw material, so that the unloader 5 unloads and rotates. At the same time, the rotation of the first shaft 74 will rotate the rotating roller 76, and with the assistance of the auxiliary roller 77, it guides the protective film base paper to be rolled up;

[0054] When the protective film on the protective film raw material moves to the predetermined position at the upper end of the film stripping frame 9, the stepping motor 72 is stopped first, and then the Z-axis driver 34 is started, thereby driving the film absorbing plate 3 and the rotator 33 to move downward, so that the film absorbing plate 3 and the protective film on the protective film raw material are adhered to each other, and then the vacuum generator is used to form a negative pressure in the vacuum chamber of the film absorbing plate 3, and the protective film is adsorbed to the lower end of the film absorbing plate 3 under the action of the negative pressure, and then the pulling plate cylinder 95 is started, thereby driving the functional frame 91, the film stripping frame 9 and the second mounting frame 92 to move rightward, and the rightward movement of the second mounting frame 92 will cause the third guide wheel 93 to move rightward, thereby exerting traction on the protective film base paper, and with the assistance of the rightward movement of the film stripping frame 9, the protective film base paper and the protective film are peeled off, thereby realizing automatic mechanical peeling of the protective film, effectively reducing the probability of damage to the peeled protective film, and effectively ensuring the film laminating effect and quality;

[0055] Then start the X-axis driver 32, thereby driving the Y-axis driver 35, the film absorbing plate 3 and other components to move to the left, so that the adsorbed protective film is moved to just above the CCD light source 2, and then start the CCD light source 2 to illuminate the adsorbed protective film, and then start the camera 13, and with the assistance of the through hole 11, to photograph the illuminated protective film, and then collect and analyze the photographed picture, and then compare the analyzed data with the preset data. If the comparison result is qualified, the X-axis driver 32 can be used to make the Y-axis driver 35, the film absorbing plate 3 and other components continue to move to the left, so that the adsorbed protective film is moved to just above the jig 12, and then the Z-axis driver 34 is used to move the adsorbed protective film downward, so that the protective film is attached to the product positioned on the jig 12, thereby completing the protective film attachment of the product;

[0056] If the comparison result is unqualified, based on the misalignment data in the comparison data, the X-axis driver 32 is used to correct the error data of the left and right positions of the adsorbed protective film, the Y-axis driver 35 is used to correct the error data of the front and back positions of the adsorbed protective film, and the rotator 33 is used to correct the tilt error data of the adsorbed protective film. The camera 13 is then used to perform visual inspection on the corrected adsorbed protective film again. If the comparison result is qualified, the protective film bonding operation is performed. If the comparison result is unqualified, the correction movement is continued to achieve deviation correction of the adsorbed protective film, effectively reducing the probability of misalignment of the bonded protective film due to factors such as mechanical peeling, and effectively ensuring the bonding effect and quality of the protective film.

[0057] When the feeder 5 discharges the protective film raw material, the servo motor is first started to drive the bidirectional screw rod 6 to rotate, thereby applying a forward and backward bidirectional driving force to the protective film raw material, so as to achieve a flattening process on the discharged protective film raw material, effectively reducing the probability of misalignment of the protective film due to factors such as wrinkles, and effectively ensuring the bonding effect and quality of the protective film;

[0058] The elastic member 84 is in a compressed state, so that the elastic member 84 itself has elastic force, and during the process of discharging the protective film raw material by the discharger 5, if the discharged protective film raw material is in a relaxed state, the pull rod 83 and the limit plate 85 are moved downward under the elastic force of the elastic member 84, and then with the assistance of the rotary connector 86, the pressure plate 81 is rotated around the second axis 88, so that the pressure wheel 87 is moved downward, and then the protective film raw material is pressed down, so as to achieve tensioning of the discharged protective film raw material, effectively reducing the probability of the protective film not being adsorbed due to factors such as relaxation of the discharger 5 during discharge, and effectively ensuring the bonding effect and quality of the protective film.

[0059] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
