Description

Technical Field

[0001] The invention relates to the technical field of PET film fixing, and in particular to a PET film fixing device. Background Art

[0002] PET film is also known as high temperature resistant polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability. It can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration, screen protection, optical mirror surface protection and other fields. With the development of special functional films, new uses of polyester film are constantly emerging. It can be produced into mobile phone LCD protective film, LCD TV protective film, etc. PET film is a packaging film with relatively comprehensive performance. It has good transparency and gloss; it has good air tightness and fragrance retention. PET film has excellent mechanical properties, its toughness is the best among all thermoplastics, and its tensile strength and impact strength are much higher than ordinary films; it has good strength and dimensional stability, and is suitable for secondary processing such as printing and paper bags. PET film also has excellent heat resistance, cold resistance, good chemical resistance and oil resistance.

[0003] During the wafer processing, a film needs to be applied to the side of the wafer with the circuit structure to protect the circuit structure. The PET film is fixed on the machine table and aligned with the wafer.

[0004] When laminating the wafer, the laminating method is to manually pull the PET film and fix it, attach the PET film to the wafer, manually press it, and then use a cutting mechanism to cut it. After cutting, the remaining PET film needs to be manually sorted out, and only the PET film roll can be fixed. When laminating the film, a lot of manual participation is required, which is time-consuming and labor-intensive. Summary of the invention

[0037] The technical solution in the embodiment of the present application is to solve the problems of the above-mentioned background technology, and the overall idea is as follows: Example 1

[0038] See also Figure 1-12The present invention provides a technical solution: a PET film fixing device comprises a workbench 1, a PET film roller assembly 3 and a driving roller assembly 4 are respectively arranged on both sides of the upper end surface of the workbench 1, the PET film roller assembly 3 is used as a material discharge mechanism, and the driving roller assembly 4 is used as a power mechanism. A positioning mechanism 2 and a film stripping assembly 10 are arranged in the middle position of the upper end surface of the workbench 1, the positioning mechanism 2 is used to position the wafer body 9, and the film stripping assembly 10 is used to strip the PET film attached to the workbench 1. A pressing roller assembly 5 and a cutting assembly 6 are arranged on one side of the PET film roller assembly 3, the pressing roller assembly 5 is used to press the PET film, and the cutting assembly 6 cuts the PET film after the film is attached. A transition roller 7 and a waste winding assembly 8 are arranged on the lower end surface of the workbench 1, and the transition roller 7 plays a guiding role. The waste winding assembly 8 winds up and arranges the film waste, the PET film roller assembly 3 includes a winding roller 32, the driving roller assembly 4 includes a first rotating roller 42 and a second rotating roller 43 with opposite rotation directions, the pressing roller assembly 5 includes a linear motor 51 and a third electric cylinder 52, and one end of the third electric cylinder 52 is connected to the bonding roller 53, the cutting assembly 6 includes a second motor 62, the output shaft of the second motor 62 is connected to the driving arm 63, one end of the driving arm 63 is connected to the fourth electric cylinder 64, and one end of the fourth electric cylinder 64 is connected to the cutting head 65, the film stripping assembly 10 includes a fifth electric cylinder 101, and one end of the fifth electric cylinder 101 is connected to the stripping plate 102, the positioning mechanism 2 includes a first electric cylinder 21, and one end of the first electric cylinder 21 is connected to the positioning plate 22, and the wafer body 9 is placed on the positioning plate 22.

[0039] Among them, PET film material is wound on the winding roller 32 of the PET film roller assembly 3, and the rotation directions of the first roller 42 and the second roller 43 are opposite. The film material passes through the gap between the first roller 42 and the second roller 43. The first roller 42 and the second roller 43 convert the rotational force into a linear driving force to drive the film material. The film material is stretched under the action of the driving force, and the winding roller 32 rotates accordingly to discharge the PET film material.

[0040] In some examples, a first slot body 11 and a second slot body 12 are formed on the workbench 1 .

[0041] In some examples, the positioning plate 22 is embedded in the first slot body 11 , and a positioning groove is formed between the first slot body 11 and the positioning plate 22 , and the wafer body 9 is placed in the positioning groove.

[0042] The first slot body 11 and the second slot body 12 are both through slot structures. Figure 1 As shown, in the initial state, a positioning groove is formed between the first groove body 11 and the positioning plate 22, and the positioning groove is adapted to the wafer body 9 to be film-bonded. After the wafer body 9 is placed inside the positioning groove, the upper surface of the wafer body 9 and the upper surface of the workbench 1 are at the same horizontal position;

[0043] After the film is pasted and cut, the first electric cylinder 21 drives the positioning plate 22 to move upward, and the positioning plate 22 drives the wafer body 9 on it to move upward synchronously, and the wafer body 9 is pushed out to facilitate unloading. After the wafer body 9 is unloaded, the first electric cylinder 21 drives the positioning plate 22 to move downward and reset, and the positioning groove is re-formed between the first groove body 11 and the positioning plate 22.

[0044] In some examples, the driving roller assembly 4 includes two groups of second side plates 41 , wherein a gear transmission base 44 is disposed on the outer side surface of one group of second side plates 41 , and one end of the gear transmission base 44 is connected to the first motor 45 .

[0045] Among them, one end of the first roller 42 and the second roller 43 are both connected to a gear, and the gear of the first roller 42 is meshed with the gear of the second roller 43 for transmission. When the first motor 45 is working, the gear of the first roller 42 is driven to rotate, and the gear drives the first roller 42 to rotate synchronously. At the same time, through the transmission between the teeth, the gear of the second roller 43 is driven to rotate synchronously, and the gear drives the second roller 43 to rotate synchronously. Under the drive of the first motor 45, the first roller 42 and the second roller 43 are rotated in the opposite direction.

[0046] In some examples, the linear motor 51 is installed on one side of the lower end surface of the workbench 1 , and the linear motor 51 includes a slide seat, and the slide seat of the linear motor 51 is fixedly connected to the third electric cylinder 52 via a connecting frame 54 .

[0047] When the linear motor 51 is working, it drives the slide to move linearly, drives the connecting frame 54 to move linearly through the slide, drives the third electric cylinder 52 to move linearly through the connecting frame 54, and drives the laminating roller 53 to move linearly through the third electric cylinder 52;

[0048] When the third electric cylinder 52 is working, it drives the laminating roller 53 at one end thereof to move axially.

[0049] The working principle of the pressure roller assembly 5 is:

[0050] like Figure 5 and Figure 6 As shown, when the PET film material to be laminated is placed directly above the wafer body 9, the third electric cylinder 52 works to drive the laminating roller 53 to move downward, contact the PET film material, and press the film material. Then, the linear motor 51 works to drive the laminating roller 53 to move horizontally. The laminating roller 53 drives the PET film material to be tightly attached to the upper surface of the wafer body 9 to achieve laminating of the wafer body 9. After laminating is completed, the linear motor 51 and the third electric cylinder 52 work to drive the laminating roller 53 to reset.

[0051] In some examples, the cutting assembly 6 includes a frame 61, and a second motor 62 is installed on the top of the frame 61, and the output shaft of the second motor 62 is fixed between the driving arm 63, and the fourth electric cylinder 64 is fixedly arranged on one side of the lower end surface of the driving arm 63. The driving arm 63 drives the end cutting head 65 to rotate with a radius that is the final cutting radius, and the radius value can be adjusted according to usage requirements.

[0052] The working principle of the cutting assembly 6 is:

[0053] After the film lamination of the pressure roller assembly 5 is completed and reset, the fourth electric cylinder 64 works to drive the cutting head 65 to move downward to contact the PET film material. The second motor 62 works to drive the fourth electric cylinder 64 to make a circular motion through the driving arm 63. The fourth electric cylinder 64 drives the cutting head 65 at its lower end to make a circular motion synchronously. During the movement, the cutting head 65 cuts along the circumferential direction of the wafer body 9 to separate the PET film material attached to the wafer body 9.

[0054] After the cutting is completed, the fourth electric cylinder 64 drives the cutting head 65 to move up and reset, the first electric cylinder 21 works to drive the positioning plate 22 to move up, and the positioning plate 22 drives the wafer body 9 on it to move up synchronously, and the wafer body 9 is pushed out. At this time, the wafer body 9 after the film is pasted can be unloaded. After unloading, the first electric cylinder 21 works to drive the positioning plate 22 to move down and reset, and a positioning groove is re-formed between the first groove body 11 and the positioning plate 22, and the new wafer body 9 to be pasted is placed in the positioning groove to complete the loading.

[0055] In some examples, the stripping plate 102 is configured as a C-shaped structure, and the stripping plate 102 is located in the second trough 12, and the outer surface of the stripping plate 102 is coated with a non-stick layer, which effectively prevents adhesion between the stripping plate 102 and the PET film material.

[0056] The working principle of the film stripping assembly 10 is:

[0057] After the wafer body 9 is loaded, the fifth electric cylinder 101 drives the stripping plate 102 to move upward. During the upward movement of the stripping plate 102, an external force is applied to the PET film residue. Under the action of the external force, the residue is separated from the workbench 1. After the PET film residue is separated, the fifth electric cylinder 101 drives the stripping plate 102 to move downward and reset.

[0058] The PET film material is driven to move by the driving roller assembly 4, the remaining PET film material is moved out of the working position, and new complete PET film material is added at the same time, and the above actions are repeated to achieve continuous film lamination of the wafer body 9. During the whole operation process, it is only necessary to manually load and unload the wafer body 9, and the loading, unloading and cutting operations of the PET film material are all performed automatically, saving time and effort.

[0059] In some examples, a bottom plate 13 is disposed at the bottom end of the workbench 1 , and a cabinet 14 is disposed on the bottom plate 13 .

[0060] By adopting the above technical solution:

[0061] The PET film roller assembly 3 is used as a discharge mechanism, the driving roller assembly 4 is used as a power mechanism, the positioning mechanism 2 is used to position the wafer body 9, the pressing roller assembly 5 is used to press the PET film material, the cutting assembly 6 cuts the PET film material after the film is pasted, the film stripping assembly 10 is used to strip the PET film material attached to the workbench 1, the transition roller 7 plays a guiding role, and the waste winding assembly 8 winds up and organizes the residual film waste. During the entire operation, you only need to manually load and unload the wafer body 9, and the loading, unloading and cutting operations of the PET film material are all performed automatically, saving time and effort. Example 2

[0062] Based on Example 1, this example introduces the specific structure of a PET film roller assembly 3 and a waste material winding assembly 8 in a PET film fixing device. The PET film roller assembly 3 includes two groups of first side plates 31, and a second electric cylinder 33 is arranged on the outer side surface of one group of the first side plates 31. A bearing base 34 is arranged on one end of the second electric cylinder 33 and the inner side surface of the other group of the first side plates 31. The winding roller 32 is located between the two groups of bearing bases 34 and is connected to the bearing base 34 through a bearing. The bearing of the bearing base 34 uses a damping bearing, which has a certain damping force when rotating, so as to prevent the PET film from loosening due to the excessive rotation of the winding roller 32.

[0063] The winding roller 32 can rotate relative to the bearing base 34, and the material is discharged when the winding roller 32 rotates. The first roller 42 and the second roller 43 convert the rotational force into a linear driving force, thereby driving the film material and stretching the PET film material.

[0064] When the second electric cylinder 33 is working, it can drive the bearing base 34 at one end thereof to move linearly. By controlling the telescopic stroke of the second electric cylinder 33, the distance between the two groups of bearing bases 34 can be adjusted to become larger or smaller.

[0065] When the distance between the two sets of bearing bases 34 increases, the two ends of the roller 32 are placed between the two sets of bearing bases 34, and then the distance between the two sets of bearing bases 34 is driven to decrease, and the two ends of the roller 32 are pressed tightly against the two ends of the roller 32. The two ends of the roller 32 are respectively embedded in the two sets of bearing bases 34, so that the roller 32 can be quickly installed and fixed. After being fixed, the roller 32 can rotate relative to the bearing base 34 under the drive of external force.

[0066] When the winding roller 32 needs to be replaced or disassembled, the second electric cylinder 33 can be used to drive the distance between the two sets of bearing bases 34 to be larger, so that the winding roller 32 can be easily installed and disassembled.

[0067] In some examples, the waste winding assembly 8 includes a vertical plate 81, and the vertical plate 81 is welded and fixed on the lower end surface of the workbench 1, and a third motor 82 is arranged on the outer surface of the vertical plate 81, one end of the third motor 82 is connected to the clamping seat 83, one end of the clamping seat 83 is connected to the film receiving roller 84, and one end of the film receiving roller 84 is clamped and fixed in the clamping seat 83.

[0068] Among them, one end of the film collecting roller 84 is fixed in the slot between the clamping seat 83. A certain external force is applied to the film collecting roller 84, and one end of the film collecting roller 84 is inserted into the clamping seat 83, so that the film collecting roller 84 can be installed and fixed. When removing the film collecting roller 84, a certain external force is applied to the film collecting roller 84, and one end of the film collecting roller 84 can be pulled out from the inside of the clamping seat 83, which facilitates the installation and disassembly of the film collecting roller 84.

[0069] Among them, when the third motor 82 is working, it drives the clamping seat 83 to rotate, and the clamping seat 83 drives the film collection roller 84 at one end thereof to rotate synchronously. When the film collection roller 84 rotates, the cut PET film waste is rolled up and sorted, without manual sorting, saving time and labor.

[0070] By adopting the above technical solution:

[0071] By controlling the telescopic stroke of the second electric cylinder 33, the distance between the two sets of bearing bases 34 is adjusted to become larger or smaller, which facilitates the installation and disassembly of the winding roller 32. One end of the film-collecting roller 84 is fixed to the clamping seat 83 by a slot, which facilitates the installation and disassembly of the film-collecting roller 84.

[0072] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
