BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a perspective view of a tear film machine according to an embodiment of the present invention. Figure 2 is a front elevational view of the tearing device of Figure 1. Referring to FIGS. 1 and 2, in the present embodiment, the tear film machine 100 includes a carrier 110, a tearing device 120, and a clamp 130 adapted to remove the diaphragm 104 positioned on the surface 102a of the substrate 102. The carrier 110 has a bearing surface S1 for carrying the substrate 102. In other words The substrate 102 can be placed on the carrying surface S1 of the carrier 110 such that the diaphragm 104 positioned on the surface 102a of the substrate 102 faces upward.

The tearing device 120 has a movable tearing element 122, and the tearing element 122 has a contact surface S2 for contacting the edge 104a of the diaphragm 104. When the substrate 102 having the diaphragm 104 is placed on the bearing surface S1 and the contact surface S2 of the tearing member 122 contacts the edge 104a of the diaphragm 104, the contact surface S2 is at an acute angle θ with the bearing surface S1. In the present embodiment, the acute angle θ is an angle ranging between 35 degrees and 55 degrees, but the invention is not limited thereto.

On the other hand, the tearing element 122 has a tearing direction D1, such as a direction from the underlying substrate to the substrate and at an acute angle θ to the surface of the substrate, such that the tearing element 122 moves along the tearing direction D1 and is moved by The contact surface S2 contacts the edge 104a of the diaphragm 104 on the surface of the substrate 102 to drive the edge 104a of the diaphragm 104 away from the substrate 102.

In addition, after the tearing element 122 drives the edge 104a of the diaphragm 104 out of the substrate 102, the clamp 130 can clamp the edge 104a of the diaphragm 104 that has been detached from the substrate 102 and move in a direction away from the tearing device 120. The diaphragm 104 is torn from the substrate 102.

In the present embodiment, the tearing element 122 of the tearing device 120 is, for example, a belt 122a. The tearing device 120 further includes two rotors 124a and 124b. The belt 122a is coupled to the two rotors 124a and 124b, and the two rotors 124a and 124b rotate in the same direction along the rotating shafts X1 and X2, respectively, to drive the belt 122a to advance. As shown in Fig. 2, by the rotation of the rotors 124a and 124b, the lower half A2 of the belt 122a is moved in the tearing direction D1, and the upper half A1 of the belt 122a is reversely moved in the tearing direction D1.

Moreover, the tearing device 120 is disposed on one side of the carrier 110. When the substrate 102 is placed on the carrier 110, the edge 104a of the diaphragm 104 faces the tearing device 120. When the belt 122a is driven by the rotors 124a and 124b, the outer surface of the lower half A2 of the belt 122a serves as the tearing contact surface S2, contacting the edge 104a of the diaphragm 104. At this time, the contact surface S2 and the bearing surface S1 of the carrier 110 are at an acute angle θ. In other words, the diaphragm 104 placed on the base material 102 of the bearing surface S1 is at an acute angle θ with the contact surface S2. When the lower half A2 of the belt 122a moves in the tearing direction D1, the contact surface S2 of the belt 122a contacts the edge 104a of the diaphragm 104 and causes the edge 104a of the diaphragm 104 to move away from the substrate 102.

Further, the belt 122a of the present embodiment can be adjusted in number and position as needed. 3A is a schematic view of the tearing device of FIG. 1. Referring to Figure 3A, in the present embodiment, the tear-off element 122 can have two belts 122a, 122a'. The belt 122a is coupled to the two rotors 124a and 124b, and the belt 122a' is coupled to the two rotors 124a' and 124b'. The rotor 124a and the rotor 124b rotate in the same direction along the rotation axes X1, X2, respectively, to drive the belt 122a to advance, and the rotor 124a' and the rotor 124b' rotate in the same direction along the rotation axes X1', X2', respectively, and the rotation axes X1, X2 Rotating in the same direction drives the belt 122a' to advance. In addition, the two belts 122a, 122a' of the tearing element 122 can also be coupled to the two rotors 124a and 124b at the same time. The rotor 124a and the rotor 124b rotate in the same direction along the rotation axes X1 and X2, respectively, and the belt 122a and the belt 122a' move in synchronization with each other, and the present invention is not limited thereto.

When the tearing member 122 performs the tearing action, the contact faces S2, S2' of the two belts 122a, 122a' contact the diaphragm 104 near the corner 104b, respectively. Adjacent to the two edges 104a, 104a', the corners 104b of the diaphragm 104 are driven away from the substrate 102.

However, the tearing element 122 is not limited to having two belts 122a, 122a'. 3B and 3C are schematic views of a tearing device according to another embodiment of the present invention. As shown in FIG. 3B, the tearing element 122 of the tearing device 120 may have only one belt 122a, and the contact surface S2 of the belt 122a contacts the edge 104a of the diaphragm 104 near the corner 104b to drive the edge 104a of the diaphragm 104. 'Without the substrate 102.

In addition, as shown in FIG. 3C, the tearing device 120 may have three or more belts 122a, 122a', 122a" and contact the diaphragm with the contact faces S2, S2', S2" of the belts 122a, 122a', 122a". 104 is adjacent to the adjacent edges 104a, 104a' of the corner 104b, for example, wherein the contact faces S2, S2' of the two belts 122a, 122a' contact the edge 104a, and the contact surface S2" of the belt 122a" contacts the edge 104a' to The edges 104a, 104a' of the diaphragm 104 are driven away from the substrate 102. The present invention does not limit the position and number of the belts 122a as long as the tearing elements 122 can contact the diaphragm 104 and drive the edges 104a or 104a' of at least one side of the diaphragm 104. It is sufficient to separate from the substrate 102.

On the other hand, in other embodiments of the present invention, other elements having similar functions may be employed instead of the belt as the tearing element. 4A through 4C are schematic views of tearing elements of other embodiments of the present invention. As shown in FIG. 4A, the tearing element is, for example, a roller 410, wherein the circumferential surface 412 of the roller 410 serves as a contact surface to contact the edge 104a or the corner 104b of the diaphragm 104. 4B illustrates a grinding wheel 420 having a front surface 422 and a side surface 424 as a rough surface that serves as a contact surface to contact the edge 104a of the diaphragm. Or a corner 104b (Fig. 4B shows the front surface 422 contacting the corner 104b).

In addition, FIG. 4C illustrates that the tearing element is a grinding rod 430, and the grinding rod 430 contacts the edge 104a or the corner 104b of the diaphragm 104 with its rod 432 as a contact surface. Accordingly, the present invention is not limited to the type of tearing member, such as a belt, a roller, a grinding wheel, a grinding rod, or other member that provides a similar tearing effect, as the tearing member of the present invention.

Next, after the tearing element 122 drives the edge 104a of the diaphragm 104 out of the substrate 102, the clamp 130 can clamp the edge 104a of the diaphragm 104 and tear the diaphragm 104 from the substrate 102.

Figure 5 is a partial enlarged view of the jig of Figure 1. Figure 6 is a front elevational view of the jig of Figure 1. Referring to FIG. 5 and FIG. 6 , in the present embodiment, the clamp 130 includes a cylinder ejector pin 132 and a fixing rod 134 that can respectively support the upper and lower surfaces of the diaphragm 104 that has been separated from the substrate 102 . When the edge 104a of the diaphragm 104 is detached from the substrate 102, the cylinder ejector pin 132 of the clamp 130 contacts the upper surface of the edge 104a, and the fixed rod 134 bears against the lower surface of the edge 104a to be clamped by the cylinder thimble 132 and the fixed rod 134. The membrane 104 is further removed from the substrate 102 by the edge 104a of the membrane 104.

Furthermore, the jig 130 of the present embodiment is disposed on the other side of the carrier 110 opposite to the tearing device 120. After the tearing device 120 carries the edge 104a of the diaphragm 104 away from the substrate 102, the clamp 130 positioned on the other side of the carrier 110 moves to the side of the tearing device 120 to grip the edge 104a of the diaphragm 104. The jig 130 is moved along the tear film direction D2 to tear the film 104 from the substrate 102.

The jig 130 of the embodiment clamps the diaphragm beside the tearing device 120 The edge 104a of the 104 is such that the tear film direction D2 of the present embodiment is away from the tearing device 120. As such, when the clamp 130 is moved away from the tear film direction D2 away from the tearing device 120 to tear off the diaphragm 104, the clamp 130 can be returned to the original position without interfering with the tearing device 120.

Referring to FIG. 1 , in the embodiment, the tear film machine 100 further includes a sensing component 140 . The sensing component 140 is disposed on the periphery of the carrier 110 for detecting the position of the edge 104a of the diaphragm 104. When the sensing element 140 detects that the edge 104a of the diaphragm 104 is detached from the substrate 102 and moved to a position such that the cylinder thimble 132 and the fixed rod 134 are adapted to bear against the upper and lower surfaces of the edge 104a of the diaphragm 104, The clamp 130 is moved to the edge 104a of the diaphragm 104 to grip the edge 104a of the diaphragm 104.

In addition, in the embodiment, the tearing machine table 100 has a first transmission module 150 and a second transmission module 160 for driving the components of the tearing machine table 100 to operate. In detail, the first transmission module 150 is coupled to the clamp 130 to drive the clamp 130 to move between the initial position P1 and the clamping position P2. As previously mentioned, the clamp 130 of the present embodiment is disposed adjacent to the carrier 110 and opposite the other side of the tear-off device 120, here the initial position P1 of the clamp 130.

After the tearing device 120 takes the edge 104a of the diaphragm 104 away from the substrate 102, the first transmission module 150 drives the third transmission module 170, the fourth transmission module 180, and the clamp 130 to move to the transition position P12, and then The third transmission module 170 drives the fourth transmission module 180 and the clamp 130 to move to the edge of the tearing device 120 to clamp the edge 104a of the diaphragm 104, which is the clamping position P2 of the clamp 130.

After the clamp 130 grips the edge 104a of the diaphragm 104 at the clamping position P2, the clamp 130 moves along the tear film direction D2 to tear the diaphragm 104 from the substrate 102. Therefore, the tear film direction D2 can be regarded as the direction in which the jig 130 is moved from the gripping position P2 to the peeling position P3.

The clamp 130 of the present embodiment is clamped in such a manner that the cylinder ejector pin 132 and the fixed rod 134 bear against the upper and lower surfaces of the edge 104a of the diaphragm 104 that has been detached from the substrate 102. Therefore, the tear film machine 100 has a fourth transmission module 180 and a third transmission module 170 for driving the cylinder thimble 132 and the fixed rod 134.

Specifically, the third transmission module 170 and the fourth transmission module 180 are coupled to the clamp 130. When the edge 104a of the diaphragm 104 is separated from the substrate 102, the first transmission module 150 drives the third transmission module 170, the fourth transmission module 180, and the clamp 130 to move to the transition position P12, and then the third transmission module 170. The fourth transmission module 180 and the clamp 130 are driven to move to the clamping position P2. When the third transmission module 170 is actuated, the fixing rod 134 can be inserted into the lower side of the edge 104a and abut against the lower surface, and the fourth transmission The module 180 drives the cylinder thimble 132 against the upper surface of the edge 104a. Accordingly, the clamp 130 can grip the edge 104a of the diaphragm 104 and move along the tear film direction D2 to tear the diaphragm 104 from the substrate 102.

On the other hand, the second transmission module 160 of the tear film machine 100 is coupled to the tearing device 120 to drive the tearing device 120 to move relative to the carrier 110. The second transmission module 160 drives the tearing device 120 to move from the standby position (not shown) to the tearing position (not shown) to approach the substrate 102, so that the tearing element 122 contacts the film at the tearing position. The edge 104a of the sheet 104 is torn After the tearing action is completed and the clamp 130 grips the edge 104a of the diaphragm 104, the tearing device 120 is moved to the standby position.

In addition, the tear film machine 100 can also be provided with an adjustment module 190. The adjustment module 190 is coupled to the tearing device 120 for adjusting the moving speed of the contact surface S2 of the tearing element 122 when the tearing device 120 performs the tearing action.

The tear film method implemented using the tear film machine 100 of the present embodiment will be further described below. 7A to FIG. 7F are schematic diagrams showing the operation of the tearing machine table 100 of FIG. 1 in performing the steps in the tear film removing method, and omitting part of the components, and only showing the components that act or perform the functions in the respective steps, so as to make the figure The style is clearer. Therefore, when referring to the front view of FIG. 7A to FIG. 7F in order, the perspective view of the tearing machine table 100 of FIG. 1 can be respectively combined to make the description clearer. In the following, the execution steps of the tear film method will be described in order with the text matching diagram.

First, referring to FIG. 1 and FIG. 7A, the substrate 102 is placed on the carrier 110. In detail, the surface 102a of the substrate 102 has a diaphragm 104 thereon. In the present embodiment, the substrate 102 is, for example, a polarizer, and the film 104 is a release film attached to the surface of the polarizer. The substrate 102 is placed on the carrying surface S1 of the carrier 110 such that the diaphragm 104 positioned on the surface 102a of the substrate 102 faces upward. In addition, the carrier 110 has a positioning structure 112 located on adjacent sides of the bearing surface S1, for example, a side having a higher height. Thus, the substrate 102 is positioned on the carrier surface S1 via the positioning structure 112.

On the other hand, the carrier 110 adsorbs the substrate 102 by means of a vacuum device (not shown) such that the substrate 102 is fixed to the bearing surface S1. The positioning structure 112 has a notch 112a at a corner between the two sides. When the substrate 102 is placed on the carrying surface S1, the substrate 102 can expose the substrate via the notch 112a. 102, so that the contact surface S2 of the tearing element 122 can contact the edge or corner of the diaphragm 104 via the notch 112a in the next step. At this time, the tearing device 120 is in the standby position without contacting the carrier 110 and the substrate 102.

Next, referring to FIG. 1 and FIG. 7B, the contact surface S2 of the tearing element 122 of the tearing device 120 contacts the edge 104a of the diaphragm 104. In detail, the second transmission module 160 drives the tearing device 120 from the standby position toward the carrier 110 to the tearing position such that the contact surface S2 contacts the edge 104a of the diaphragm 104 at the tearing position.

Next, referring to FIG. 1 and FIG. 7C, the contact surface S2 moves in the tearing direction D1 to drive the edge 104a of the diaphragm 104 away from the substrate 102. The tearing direction D1 is at an acute angle to the surface 102a of the diaphragm 104. At this time, the adjustment module 190 can adjust the moving speed of the contact surface S2 of the tearing element 122.

Next, referring to FIG. 1 and FIG. 7D, when the sensing element 140 disposed on the periphery of the carrier 110 is omitted from the other operating diagrams for clarity of the illustration, the sensing component 140 is not shown to this step. Moving to the side of the carrier 110) When the edge 104a of the diaphragm 104 is detected to be separated from the substrate 102 and moved to the positioning, the first transmission module 150 drives the third transmission module 170, the fourth transmission module 180, and the clamp 130 first. Moving from the initial position P1 to the transition position P12, the third transmission module 170 then drives the fourth transmission module 180 and the clamp 130 to move from the transition position P12 to the clamping position P2.

Next, referring to FIG. 1 and FIG. 7E, the edge 104a of the diaphragm 104 of the substrate 102 is held by the clamp 130. When the first transmission module 150 drives the third transmission module 170, the fourth transmission module 180 and the clamp 130 to move to the transition position P12, then the third transmission module 170 drives the fourth transmission. The module 180 and the clamp 130 are moved to the clamping position P2, and when the third transmission module 170 is actuated, the fixing rod 134 can be inserted into the lower side of the edge 104a and abut against the lower surface, and the fourth transmission module 180 The cylinder thimble 132 is driven against the upper surface of the edge 104a such that the cylinder thimble 132 and the fixed rod 134 collectively grip the edge 104a of the diaphragm 104.

Next, referring to FIG. 1 and FIG. 7F, the first transmission module 150 drives the clamp 130 to move to the tear-off position P3 along the tear film direction D2 to tear the diaphragm 104 from the substrate 102, and the tear film direction D2. That is, the direction away from the tearing device 120. At this point, the tear film machine 100 completes the tear film action.

Referring to FIG. 1, after the diaphragm 104 is completely removed from the substrate 102, the clamp 130 also comes to the tear-off position P3. At this time, the fourth transmission module 180 does not actuate the cylinder ejector pin 132, and separates the cylinder ejector pin 132 from the fixed rod 134 to release the clamping diaphragm 104, causing the diaphragm 104 to fall into the membrane disposed under the tear-off position P3. Sheet recovery area 106. Finally, the third transmission module 170 is not activated to return to the initial position P1, and the first transmission module 150, the third transmission module 170, and the fourth transmission module 180 are all returned to the initial position P1.

After the clamp 130 holds the edge 104a of the diaphragm 104, the edge 104a of the diaphragm 104 does not have to be maintained in a state of being detached from the substrate 102 by the contact surface S2. Therefore, after the clamp 130 clamps the edge 104a of the diaphragm 104, the second transmission module 160 can immediately move the tearing device 120 from the tearing position toward the direction away from the carrier 110 to return to the standby position.

However, the second transmission module 160 can also wait until the tearing machine 100 completes the tearing action, and even waits until the first transmission module 150, the third transmission module 170, and the fourth transmission module 180 drive the clamp 130 and the clamp 130. Cylinder top After the needle 132 and the fixing rod 134 return to the initial position P1, the tearing device 120 is moved to the standby position, as long as the respective driving modules drive the members of the tearing machine table 100 to move without interfering with each other.

In summary, the present invention provides a tearing machine table and a tearing filming method. The tearing device of the tearing machine table has a tearing member that contacts the edge of the film on the surface of the substrate and drives the edge of the film. The substrate is detached from the substrate, and the clamp of the tear film machine is held away from the edge of the film of the substrate and moved away from the tearing device to tear the film away from the substrate. In addition, each transmission module of the tear film machine can drive the tearing device and the clamp of the tear film machine to perform the tearing action. Therefore, the present invention can replace the conventional tear film method using consumables (such as tape), reduce the tear film cost, and realize an automated tear film step.
