Description

Sticking film machine and film roll replacing device thereof

Technical Field

The invention relates to a film sticking machine, in particular to a film sticking machine of an improved film roll replacing device.

Background

Currently, in the semiconductor or electronic component industry, some processes require attaching a film material (such as an ABF film) on a substrate to prevent dust adhesion, achieve electrostatic protection, or block air contact. In a production line, because a film pasting machine continuously performs the operation of pasting the film material on the substrate, and the length of the film material of a single film roll is limited, the film roll needs to be replaced after a period of time.

At present, the operation of replacing the film roll is mostly carried out in a manual mode, which not only has frequent steps and large labor intensity, but also seriously affects the production efficiency and increases the production cost because the operation of the production line needs to be suspended when the film roll is replaced, and the products on the production line have high probability of being scrapped. In pursuit of continuous operation of the production line, automatic production and cost reduction, the development of a device capable of replacing the film roll has become an urgent technical problem to be solved.

Although there are devices developed to replace film rolls using specific mechanisms and automated handling, many problems still remain. Furthermore, the existing film roll replacing mechanism cannot avoid the attachment of the butt joint of the film roll to the substrate after the film roll is replaced, and the butt joint of the film roll has wrinkles, scratches or uneven thickness, which results in poor film attaching quality. In addition, because the mechanism part for changing the film roll needs to be additionally installed, the whole volume of the film pasting machine table becomes overlarge, and the film pasting machine table is not convenient to carry.

Disclosure of Invention

The invention aims to provide a film roll replacing device, which is beneficial to solving the problems of reduced production efficiency and increased production cost caused by manual film roll replacement and the problems of poor film sticking quality and increased machine table volume caused by the conventional film roll replacing device. The invention further provides a film sticking machine carrying the film roll replacing device.

The film roll replacing device disclosed by the invention comprises a film butting mechanism and a film roll replacing mechanism. The film butting mechanism is used for butting the first film roll and the second film roll. The film roll replacing mechanism comprises a substrate bearing roller and a winding roller which are linked. The substrate bearing roller and the winding roller can rotate around the axle center, so that the film roll replacing mechanism has a standby state and a winding state. In a standby state, the substrate carrying roller corresponds to the film butting mechanism. And when in a winding state, the winding roller corresponds to the film butting mechanism.

The invention further discloses a film sticking machine which comprises a film sticking device and a film roll replacing device. The film sticking device comprises a film sticking component and a film pressing component. The film roll replacing device comprises a film butting mechanism and a film roll replacing mechanism. The film butting mechanism is used for butting the first film roll and the second film roll, and the film butting mechanism is provided with a feeding side of the film sticking component. The film roll replacing mechanism is arranged between the discharging side of the film sticking assembly and the feeding side of the film pressing assembly. The film roll replacing mechanism comprises a substrate bearing roller and a winding roller which are linked. The substrate bearing roller and the winding roller can rotate around the axle center, so that the film roll replacing mechanism has a standby state and a winding state. In a standby state, the substrate bearing roller corresponds to the film sticking device. And when in a furling state, the furling roller corresponds to the film sticking device.

According to the film roll replacing device and the film sticking machine disclosed by the invention, the film roll replacing mechanism comprises the substrate bearing roller and the winding roller, and the substrate bearing roller and the winding roller can rotate in a linkage manner. The film roll replacing mechanism has a standby state in which the substrate carrying roller is available and a winding state in which the winding roller is available, depending on the positions of the substrate carrying roller and the winding roller. When the film roll does not need to be replaced, the substrate bearing roller is used for bearing the substrate and guiding and conveying the substrate to a working area for film pasting operation. Once the film roll needs to be replaced, the film roll replacing mechanism can roll up the residual film material of the old film roll after the roll-up roll is moved to the working position of the substrate bearing roll. Therefore, the element for film sticking operation and the element for replacing the film roll are integrated into a linkage mechanism, and the whole volume of the film sticking machine is favorably reduced.

In addition, after the new film roll is in butt joint with the old film roll, the winding roller can continue to wind the film materials until the butt joint of the new film roll and the old film roll is positioned on the winding roller, so that the film materials at the butt joint of the film rolls can be prevented from being used for film sticking operation.

The foregoing description of the present disclosure and the following detailed description are presented to illustrate and explain the principles and spirit of the present invention and to provide further explanation of the invention as claimed.

The following examples further illustrate aspects of the present invention in detail, but are not intended to limit the scope of the invention in any way.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic view of a film roll changing device according to an embodiment of the invention. Fig. 2 is a schematic view of a film roll changing mechanism of the film roll changing device of fig. 1. In the present embodiment, the film roll exchange device 1 includes a first support roller 10, a second support roller 20, a film docking mechanism 30, and a film roll exchange mechanism 40.

The first supporting roller 10 and the second supporting roller 20 are disposed at intervals, and the first supporting roller 10 and the second supporting roller 20 are respectively used for carrying a film roll (not shown). Rolls of film are for example, but not limited to, rolls of PET (polyethylene terephthalate), mylar (Mylar) or ABF film. Hereinafter, for convenience of description, the film roll carried on the first support roller 10 is referred to as a "first film roll", and the film roll carried on the second support roller 20 is referred to as a "second film roll".

The film docking mechanism 30 is used to dock a first film roll with a second film roll. In detail, the film docking mechanism 30 includes a guide roller 310, an adsorption unit 320, and a driving unit 330. Guide roll 310 is used to receive the film stock from the first roll of film. The suction unit 320 is, for example and without limitation, a suction cup for sucking the film from the second film roll. The driving unit 330 is, for example, but not limited to, a stepping motor, and is configured to drive the adsorption unit 320 to approach the film material of the first film roll, so that the film materials of the first film roll and the second film roll are butted. The docking of the film roll will be described in detail later. The film docking mechanism 30 of the present embodiment includes an adsorption unit and a driving unit, but the present invention is not limited thereto. In other embodiments, the film splicing mechanism may comprise a heating unit capable of splicing the first film roll and the second film roll by hot melting the film material.

The film roll changing mechanism 40 includes a substrate carrying roller 410 and a take-up roller 420 which are interlocked, and the substrate carrying roller 410 and the take-up roller 420 are rotatable around an axis a. In detail, the film roll changing mechanism 40 further includes a transmission shaft 430 and a mounting seat 440 disposed at one end of the transmission shaft 430. The substrate carrying roller 410 and the take-up roller 420 are rotatably provided to the mount 440. The transmission shaft 430 may be connected to a motor (not shown) to pivot the substrate supporting roller 410 and the winding roller 420 through the transmission shaft 430, such that the central axis of the transmission shaft 430 is the aforementioned axis a. In this embodiment, the take-up roll 420 has a plurality of suction holes 421 distributed on an outer surface 422 of the take-up roll 420. The suction holes 421 may be connected to a negative pressure supply device (not shown) to suck the film material, so as to wind the film material around the winding roller 420. Fig. 1 shows the take-up roll 420 having the suction holes 421, but the invention is not limited thereto. In other embodiments, the take-up roll may be a tape roll that adhesively winds and takes up the film.

The rotation of the substrate carrying roller 410 and the take-up roller 420 allows the film roll changing mechanism 40 to have a standby state and a take-up state. In the standby state, the substrate support roller 410 corresponds to the film docking mechanism 30 (shown in fig. 1). In the wound state, the winding roller 420 corresponds to the film abutment mechanism 30. The standby state and the winding-up state of the film roll changing mechanism 40 will be further described later.

In the present embodiment, the film roll exchanging apparatus 1 further includes a cutter 50 disposed corresponding to the film docking mechanism 30 and configured to cut the first film roll. The film roll changing device 1 further includes another cutter 60 disposed corresponding to the film roll changing mechanism 40 and configured to cut off the second film roll. The use of

cutters

50, 60 will be described further below. The film roll changer 1 further includes a detection unit 70 provided corresponding to the film docking mechanism 30. The detection unit 70 can output an instruction to the film roll changing mechanism 40 according to the remaining amount of the film material of the first film roll, and the film roll changing mechanism 40 can be changed from the standby state to the wound-up state according to the instruction.

Fig. 3 is a schematic view of a film sticking machine according to an embodiment of the invention. In the present embodiment, the film sticking machine 3 includes the film roll changing device 1 and the film sticking device 2. The film sticking device 2 comprises a film sticking assembly 21 and a film pressing assembly 22. The film pasting assembly 21 has, for example but not limited to, a flat supporting surface 211, and the film material from the first film roll or the second film roll can be pasted on the flat supporting surface 211 and flattened by the same for the subsequent film pasting process. The film sticking assembly 21 may be connected to a stepping motor (not shown) so that the film sticking assembly 21 can move relative to the film roll changing mechanism 40 to approach or separate from the substrate carrying roller 410 and the winding roller 420 of the film roll changing mechanism 40. The lamination assembly 22 includes a lamination wheel 221, and the cutter 60 of the film roll changing device 1 is disposed on the lamination assembly 21.

The elements of the film roll changing device 1 and the film sticking device 2 are matched with each other to form a film sticking machine which can be implemented. In detail, the roll changing mechanism 40 of the roll changing apparatus 1 is disposed between the discharging side 21b of the lamination module 21 and the feeding side 22a of the lamination module 22, and more specifically, disposed on the working path between the lamination module 21 and the lamination module 22. The cutter 50 is disposed on the feeding side 21a of the film sticking assembly 21, and the cutter 60 is disposed on the discharging side 21b of the film sticking assembly 21. The detecting unit 70 is disposed on the feeding side 21a of the film sticking module 21.

Fig. 4 to 9 are schematic views of replacing a film roll using the laminator of fig. 3. The film sticking machine 3 can stick the film material to the surface of the substrate under the normal working state. As shown in fig. 4, a first film roll 4a and a second film roll 4b are provided on the first support roller 10 and the second support roller 20 of the film roll changer 1, respectively, wherein the first film roll 4a is a film roll in use, and the second film roll 4b is a film roll for preliminary exchange. The film material from the first film roll 4a is attached to the film sticking assembly 21 of the film sticking device 2. The film material of the second film roll 4b is pulled out and one end thereof is fixed by the adsorption unit 320 of the film docking mechanism 30. In this embodiment, the second film roll 4b is pulled out and fixed in advance to facilitate the subsequent film roll replacement operation that may be required, but the invention is not limited thereto. In some embodiments, the second film roll 4b may be pulled out and fixed by the suction unit 320 until it is determined that the film roll change operation is necessary.

The substrate 5 is guided by the substrate carrying roller 410 of the film roll changing mechanism 40 and is conveyed to below the film sticking assembly 21. The film pasting assembly 21 moves down to approach the substrate 5 to make the film material of the first film roll 4a contact the surface of the substrate 5, and the substrate 5 is continuously pushed to approach the film pressing assembly 22 of the film pasting device 2, so as to tightly adhere the film material to the surface of the substrate 5 by the film pressing wheel 221. After the operation of attaching the film material to the surface of the substrate 5 is completed, the film material is cut by the cutter 60, and the film attaching assembly 21 moves up away from the substrate 5 and returns to the original position. In fig. 3 and 4, the film roll changing mechanism 40 is in a standby state, in which the substrate carrying roller 410 corresponds to the film laminating device 2 and the film docking mechanism 30, and more specifically, the substrate carrying roller 410 is closer to the film laminating device 2 and the film docking mechanism 30 than the take-up roller 420.

After the work of attaching the film to the substrate is performed a plurality of times, the film of the first film roll 4a is gradually decreased, and the detection unit 70 of the film roll changing device 1 monitors the film remaining amount of the first film roll 4a in real time. The residual amount of the film material may be monitored by monitoring the thickness of the first film roll 4a or the distance between the outermost film material of the first film roll 4a and the detecting unit 70. As shown in fig. 5, when the detection unit 70 detects that the remaining amount of the film material of the first film roll 4a is too low, the detection unit 70 outputs a command to the roll changing mechanism 40. Upon receiving the command, the film roll changing mechanism 40 changes the standby state shown in fig. 4 to the rolled state shown in fig. 5. More specifically, when the standby state is changed to the winding state, the substrate carrying roller 410 and the winding roller 420 are switched, and at this time, the winding roller 420 corresponds to the film laminating device 2 and the film joining mechanism 30, that is, the winding roller 420 is closer to the film laminating device 2 and the film joining mechanism 30 than the substrate carrying roller 410. The present embodiment describes the state of the automatic control of the film roll changing mechanism by the detection unit 70, but the present invention is not limited thereto. In other embodiments, the detection unit may emit a sound or text type warning message to notify the operator that the residual film material is too low, so that the operator can manually change the state of the film roll changing mechanism.

As shown in fig. 6, the film roll changing mechanism 40 in the roll-up state can take up the remaining film material of the first film roll 4a by the roll-up roller 420. In detail, the film sticking assembly 21 moves down to approach the winding roller 420, and the winding roller 420 sucks the remaining film material of the first film roll 4a through the suction hole 421 and then rotates for winding; here, the rotation of the take-up roller 420 means rotation about its axis. The rotation of the take-up roller 420 may be performed manually by an operator or by an external drive (not shown).

Next, the second film roll 4b to be used is appropriately set for the subsequent butt joint operation. As shown in fig. 7, the second film roll 4b is butted against the remaining first film roll 4a to mount the second film roll 4b on the machine. The driving unit 330 moves the adsorption unit 320 close to the first film roll 4a positioned at the film docking mechanism 30 so that the second film roll 4b can be adhered to the first film roll 4a. In this embodiment, the first film roll 4a and the second film roll 4b are both film materials having single-sided tackiness, and here, the non-tacky surface of the second film roll 4b contacts the tacky surface of the first film roll 4a, thereby completing the butt joint of the first film roll 4a and the second film roll 4b. In the embodiment, the adsorption unit 320 and the driving unit 330 are used to complete the film material butt joint, but the invention is not limited thereto. In other embodiments, it may be that an operator manually affixes the second film roll 4b to the first film roll 4a. After the first film roll 4a and the second film roll 4b are butted, the cutter 50 cuts the first film roll 4a in the region between the first support roller 10 and the film butting mechanism 30.

The take-up roller 420 of the film roll changing mechanism 40 continues to take up the film material until the second film roll 4b is conveyed to the film sticking assembly 21 of the film sticking device 2. As shown in fig. 8, the remaining film of the first film roll 4a is completely wound up by the winding-up roller 420 rotating. To prevent the first roll 4a from being used in a subsequent lamination process at the interface with the second roll 4b, the take-up roller 420 then takes up a portion of the leading film web of the second roll 4b until the film web of the second roll 4b fills the working path between the lamination assembly 21 and the lamination assembly 22. Next, the cutter 60 cuts the second roll 4b in the area between the laminating unit 21 and the laminator unit 22, and separates the web of the second roll 4b positioned in the laminating unit 21 from the take-up roller 420.

As shown in fig. 9, when the film roll changing mechanism 40 returns from the rolled state to the standby state, the substrate carrying roller 410 and the rolling roller 420 exchange positions again, and at this time, the substrate carrying roller 410 returns to a position close to the laminating unit 21, so that the substrate 5 can be guided to enter the film laminating unit 22 after being laminated with the film material of the second film roll 4b in the subsequent laminating operation.

In summary, according to the film roll replacing device and the film laminating machine disclosed in the present invention, the film roll replacing mechanism includes the substrate carrying roller and the winding roller, and the substrate carrying roller and the winding roller can rotate in a linkage manner. The film roll replacing mechanism has a standby state in which the substrate carrying roller is available and a winding state in which the winding roller is available, depending on the positions of the substrate carrying roller and the winding roller. When the film roll does not need to be replaced, the substrate bearing roller is used for bearing the substrate and guiding and conveying the substrate to a working area for film pasting operation. Once the film roll needs to be replaced, the film roll replacing mechanism can roll up the residual film material of the old film roll after the roll-up roll is moved to the working position of the substrate bearing roll. Therefore, the element for film pasting operation and the element for replacing the film roll are integrated into a linkage mechanism, and the whole volume of the film pasting machine is favorably reduced.
