Description

Technical Field

[0001] The invention relates to a release film processing device, and more particularly to a release film stripping device. Background Art

[0002] The main function of the release film peeling device is to overcome the adhesive force between the release film and the substrate by applying shear force, thereby achieving peeling. Its working principle is based on the basic principle of bonding mechanics, that is, there is an adhesive force between the sample (i.e., the release film) and the substrate. When a sufficiently large shear force is applied, the sample will peel off from the substrate. The peeling device evaluates the quality and performance of the release film by recording the minimum shear force required to achieve peeling.

[0003] Conventional release film peeling devices can usually only peel off one side of a substrate when in use. When peeling off the other side, the substrate needs to be turned over, which will significantly increase production time and labor costs, thereby reducing production efficiency.

[0004] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a release film peeling device, which drives two peeling knives to move left and right through two adjustment plates to approach the left and right sides of the substrate, and pushes the movable block and the movable concave plate to move downward through the first cylinder, thereby pushing the two peeling knives to contact the surface of the substrate. The two peeling knives act on the left and right sides of the substrate respectively, realizing simultaneous peeling on both sides. Compared with single-sided peeling, the peeling efficiency is significantly improved, labor costs are saved and production time is shortened.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions: a release film peeling device, comprising a workbench, a base is fixedly installed on the upper end of the workbench, a substrate is placed on the upper end of the base, a fixing frame is fixedly installed on the rear side of the upper end of the workbench, a first cylinder is fixedly installed on the upper end of the fixing frame, a movable block is fixedly installed on the output end of the first cylinder, a movable concave plate is fixedly installed on the front end of the movable block, a driving mechanism is arranged inside the movable concave plate, an adjustment plate is threadedly connected to the left and right sides of the outer surface of the driving mechanism, a stripping knife is fixedly installed on the opposite surfaces of the two adjustment plates, a second cylinder is arranged on the left and right sides of the upper end of the workbench, and a positioning plate is fixedly installed on the output ends of the two second cylinders.

[0007] The present invention is further configured as follows: the driving mechanism includes a forward and reverse threaded rod, a servo motor is fixedly installed on the right end of the forward and reverse threaded rod, the servo motor is fixedly connected to the right end of the movable concave plate, and the adjustment plate is threadedly connected to the outer surface of the forward and reverse threaded rod.

[0008] The present invention is further configured as follows: a storage groove is provided at the upper end of the positioning plate.

[0009] The present invention is further configured as follows: four support blocks are fixedly installed at the lower end of the workbench.

[0010] The present invention is further configured as follows: the fixing frame is configured in a U-shaped shape.

[0011] The present invention is further configured such that: the positioning plates are located on the left and right sides of the substrate.

[0012] The present invention is further configured such that: the adjustment plate and the workbench maintain a parallel position relationship.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. The two stripping knives are driven by two adjustment plates to move left and right close to the left and right sides of the substrate. The first cylinder pushes the movable block and the movable concave plate downward, thereby pushing the two stripping knives to contact the surface of the substrate. The two stripping knives act on the left and right sides of the substrate respectively, realizing double-sided stripping at the same time. Compared with single-sided stripping, the stripping efficiency is significantly improved, labor costs are saved and production time is shortened. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] The present invention will be described in detail below with reference to the accompanying drawings.

[0023] A release film peeling device, as Figures 1 to 3 shown, includes a workbench 1. A base 2 is fixedly installed at the upper end of the workbench 1. A base material 3 is placed on the upper end of the base 2. A fixing frame 4 is fixedly installed at the rear side of the upper end of the workbench 1. The fixing frame 4 is arranged in a shape of a Chinese character 'hui'. A first cylinder 5 is fixedly installed at the upper end of the fixing frame 4. An output end of the first cylinder 5 is fixedly installed with a movable block 6. A movable concave plate 7 is fixedly installed at the front end of the movable block 6. A driving mechanism 8 is arranged inside the movable concave plate 7. A regulating plate 9 is threadedly connected to both the left and right sides of the outer surface of the driving mechanism 8. The regulating plate 9 and the workbench 1 maintain a parallel positional relationship. A peeling knife 10 is fixedly installed on each of the opposite surfaces of the two regulating plates 9. A second cylinder 11 is arranged on each of the left and right sides of the upper end of the workbench 1. An output end of each of the two second cylinders 11 is fixedly installed with a positioning plate 12. The positioning plates 12 are located on the left and right sides of the base material 3. When the two regulating plates 9 drive the two peeling knives 10 to move left and right, they approach the left and right side surfaces of the base material 3. By pushing the movable block 6 and the movable concave plate 7 downward through the first cylinder 5, the two peeling knives 10 are pushed to contact the surface of the base material 3. The two peeling knives 10 act on the left and right sides of the base material 3 respectively, realizing simultaneous bilateral peeling. Compared with unilateral peeling, the peeling efficiency is significantly improved, the labor cost is saved, and the production time is shortened.

[0024] A storage groove 13 is opened at the upper end of the positioning plate 12. The storage groove 13 is provided for collecting the impurity debris that falls off from the peeled base material 3.

[0025] Four support blocks 14 are fixedly installed at the lower end of the workbench 1. The support blocks 14 are provided to play a role in supporting and stabilizing the workbench 1.

[0026] like Figure 2 As shown, the driving mechanism 8 includes a forward and reverse threaded rod 81, and a servo motor 82 is fixedly installed on the right end of the forward and reverse threaded rod 81. The servo motor 82 is fixedly connected to the right end of the movable concave plate 7, and the adjustment plate 9 is threadedly connected to the outer surface of the forward and reverse threaded rod 81. The servo motor 82 drives the forward and reverse threaded rod 81 to rotate. Since the left and right ends of the forward and reverse threaded rod 81 have threads with different rotation directions respectively, the nuts or the adjustment plate 9 with nuts arranged at both ends of the forward and reverse threaded rod 81 can move relative to each other.

[0027] Working principle: by starting the second cylinder 11 to drive the positioning plate 12 to move, the substrate 3 on the base 2 is clamped and fixed, and the servo motor 82 drives the positive and negative threaded rod 81 to rotate. Since the left and right ends of the positive and negative threaded rod 81 have threads with different rotation directions, the nuts or adjustment plates 9 with nuts provided at both ends of the positive and negative threaded rod 81 can move relative to each other. The two adjustment plates 9 drive the two stripping knives 10 to move left and right to approach the left and right sides of the substrate 3. The first cylinder 5 pushes the movable block 6 and the movable concave plate 7 to move downward, thereby pushing the two stripping knives 10 to contact the surface of the substrate 3. The two stripping knives 10 act on the left and right sides of the substrate 3 respectively, realizing double-sided stripping at the same time. Compared with single-sided stripping, the stripping efficiency is significantly improved, labor costs are saved and production time is shortened.

[0028] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
