Description

Technical Field

[0001] This invention relates to the field of automation equipment technology, and in particular to a film-tearing module and a material transfer device. Background Technology

[0002] In the manufacturing process of products such as laser ranging modules, materials need to be supported by a membrane. For example, in the chip mounting step, the PCB board needs to be adhered to the membrane first, and then the chip is mounted on the PCB board. In order to reliably fix the materials and prevent them from shifting relative to the membrane during the process, a high-viscosity membrane is used in the aforementioned steps. However, when the materials are separated from the membrane by a robot after the aforementioned steps are completed, the high adhesion of the high-viscosity membrane can actually hinder the separation of the materials. Therefore, the current common practice is to first adhere the materials with a low-viscosity membrane, then separate the high-viscosity membrane from the materials using a film-peeling module, thereby transferring the materials to the low-viscosity membrane, and finally separating the materials from the low-viscosity membrane using a robot. Since the high-viscosity film is attached to the substrate, the film-removing module usually includes a pre-removal mechanism and a film-removal mechanism. The pre-removal mechanism is used to separate the local edge of the high-viscosity film from the substrate. Then, the film-removal mechanism fixes the local edge that has been separated from the substrate and then drives the high-viscosity film to completely separate from the substrate. In related technologies, the pre-removal mechanism and the film-removal mechanism are driven by two independent mechanisms, which increases the structural complexity and cost on the one hand, and the control difficulty on the other hand. Summary of the Invention

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a film-tearing module that simplifies the structure and control, and reduces costs.

[0004] The present invention also proposes a material transfer device that applies the aforementioned film-tearing module.

[0005] A film-peeling module according to a first embodiment of the present invention is used to separate a first film from a first substrate, and includes a first base, a pre-peeling device, a first clamping device, a first driving device, and a second driving device.

[0006] The pre-tear film device includes a film-scraping component. The first driving device is connected to the first base, and the film-scraping component is connected to the first driving device and can be driven by the first driving device to switch between a first extended state and a first retracted state.

[0007] The first clamping device includes a first clamping component and a second clamping component. The second driving device is connected to the first base. At least one of the first clamping component and the second clamping component is connected to the second driving device and can be driven by the second driving device to switch the first clamping device between a first clamping state and a first open state. When the film scraping component is in the first extended state, it is located between the first clamping component and the second clamping component.

[0008] The film-peeling module is configured as follows:

[0009] When the first substrate with the first film bonded to it is placed on the external support module, and the film-scraping component is in the first extended state and abuts against the edge of the first film, the film-tearing module and the support module move relative to each other, so that the film-scraping component extends into the space between the edge of the first film and the first substrate, and so that the edge of the first film is located between the first clamping component and the second clamping component.

[0010] When the edge of the first film is located between the first clamping member and the second clamping member, and the film scraping member is in the first retracted state, the first clamping device switches from the first open state to the first clamping state to clamp the edge of the first film.

[0011] After the first clamping device clamps the edge of the first film, the film tearing module and the carrier module move relative to each other to separate the first film from the first substrate.

[0012] The film-peeling module according to the first embodiment of the present invention has at least the following beneficial effects:

[0013] This embodiment achieves partial and complete detachment of the first film edge by switching the film-scraping component between the first extended state and the first retracted state, and by switching the first clamping device between the first clamping state and the first open state. During this process, the pre-tear film device and the first clamping device do not need to be moved to the working position and reset separately, which can improve efficiency and simplify control. In addition, this embodiment integrates the pre-tear film device and the first clamping device into the first base and drives them in a unified manner, which can simplify the structure and reduce costs.

[0014] In other embodiments of the present invention, relative movement occurs between the film-tearing module and the carrier module, such that the film-scraping component extends between the edge of the first film and the first substrate, and the edge of the first film is positioned between the first clamping component and the second clamping component, including:

[0015] The film-tearing module and the carrier module undergo a first horizontal movement to allow the film-scraping component to extend between the edge of the first film and the first substrate. Then, the film-tearing module and the carrier module undergo a second vertical movement to allow the film-scraping component to move the edge of the first film away from the first substrate. After the second movement, the film-tearing module and the carrier module undergo a third horizontal movement to position the edge of the first film between the first clamping component and the second clamping component.

[0016] In other embodiments of the present invention, the carrying module moves horizontally to perform the first movement;

[0017] And / or, the film-tearing module moves vertically upward to perform the second movement;

[0018] And / or, the carrier module moves horizontally to perform the third movement.

[0019] In other embodiments of the present invention, after the second movement occurs, a third horizontal movement occurs between the film-tearing module and the carrier module, including:

[0020] After the second movement occurs, the film-scraping component first switches from the first extended state to the first retracted state, and then the third movement occurs between the film-tearing module and the carrier module.

[0021] In other embodiments of the present invention, when the film scraping component is in the first extended state and abuts against the edge of the first film, the first clamping device is in the first clamping state to clamp the film scraping component.

[0022] When the film scraping component extends between the edge of the first film and the first substrate, the first clamping device switches from the first clamping state to the first open state.

[0023] In other embodiments of the present invention, the first clamping member is connected to the second driving device, the second clamping member is connected to the first base, the first clamping member is located above the second clamping member, the second clamping member has a guide surface on the side facing the first clamping member, and the height of the guide surface gradually decreases along the direction from the fixed end to the free end of the second clamping member.

[0024] In other embodiments of the present invention, relative movement occurs between the film-peeling module and the carrier module to separate the first film from the first substrate, including:

[0025] The carrier module moves horizontally, and the film-peeling module moves vertically simultaneously to separate the first film from the first substrate.

[0026] In other embodiments of the present invention, the film-tearing module includes an auxiliary device and a third driving device. The auxiliary device includes a first auxiliary roller connected to the third driving device and capable of being driven to move by the third driving device.

[0027] The relative movement between the film-peeling module and the carrier module, to separate the first film from the first substrate, includes:

[0028] When the tearing module and the carrier module move relative to each other to separate part of the first film from the first substrate, the third driving device drives the first auxiliary roller to move until it comes into contact with the first film. After the first auxiliary roller comes into contact with the first film, the tearing module and the carrier module move relative to each other again to completely separate the first film from the first substrate. In the direction of horizontal movement of the carrier module, the first auxiliary roller comes into contact with the front side of the first film.

[0029] In other embodiments of the present invention, the auxiliary device further includes a second auxiliary roller, and the film-tearing module further includes a fourth driving device, wherein the second auxiliary roller is connected to the fourth driving device and can be driven by the fourth driving device to move;

[0030] When the first film is completely separated from the first substrate, the fourth driving device drives the second auxiliary roller to move until it comes into contact with the first film, so as to cooperate with the first auxiliary roller to clamp the first film.

[0031] A material transfer apparatus according to a second embodiment of the present invention is used to transfer material from a first film adhered to a first substrate to a second film adhered to a second substrate, the material transfer apparatus comprising:

[0032] The feeding module is used to supply the first membrane with the adhesive material and the empty second membrane;

[0033] Bearing module;

[0034] A transfer module is used to transfer the first film and the second film supplied by the feeding module to the carrier module, so that the second film adheres to the material on the first film;

[0035] The aforementioned film-peeling module;

[0036] A collection module is used to collect the first membrane that has separated from the first substrate.

[0037] In other embodiments of the present invention, the collection module includes:

[0038] The second clamping device includes a third clamping component and a fourth clamping component disposed opposite to each other. The third clamping component has a first surface for clamping the first film, and the fourth clamping component has a second surface for clamping the first film. The second surface is an anti-stick surface.

[0039] A sixth driving device, connected to at least one of the third clamping component and the fourth clamping component, is used to drive relative movement between the third clamping component and the fourth clamping component, so that the second clamping device switches between a second clamping state and a second open state;

[0040] The film removal device is connected to the third clamping component;

[0041] A collection container, disposed below the second clamping device, is used to collect the first membrane separated from the third clamping component;

[0042] The collection module is configured such that when the second clamping device holding the first membrane switches from the second clamping state to the second open state, the first membrane separates from the fourth clamping component and adheres to the first surface of the third clamping component; and when the first membrane adheres to the third clamping component, the membrane removal device drives the first membrane to separate from the third clamping component and fall into the collection container.

[0043] In other embodiments of the present invention, the demolding device includes an ejector component having a third surface for contacting the first film, the third surface being an anti-stick surface, and the ejector component being movable relative to the third clamping component to switch the ejector component between a second extended state and a second retracted state, wherein the ejector component extends relative to the first surface when in the second extended state and retracts relative to the first surface when in the second retracted state;

[0044] The collection module is configured such that when the second clamping device is in the second clamping state, the ejector is in the second retracted state; and when the first membrane adheres to the third clamping device, the ejector is in the second extended state, so as to drive the first membrane to separate from the third clamping device.

[0069] In the description of this invention, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0070] As mentioned earlier, membranes are commonly used as carriers in material processing. Taking a laser ranging module as an example, the main assembly process of the laser ranging module includes the following steps: First, the PCB board is bonded to the membrane, then the chip is mounted on the PCB board. After mounting, leads are bonded between the chip and the PCB board. After bonding the leads, a protective cover is attached to protect the chip and the leads. To ensure that there is no displacement between the PCB board and the membrane during the process, a membrane with strong adhesion is required as the carrier. However, using a high-adhesion membrane as the carrier increases the difficulty of separating the material (such as the aforementioned PCB board with the chip and protective cover) from the membrane. Therefore, there is currently a membrane-based material transfer scheme, the general principle of which is described in [reference needed]. Figure 1 This requires the use of two films with different adhesive strengths and two substrates. For ease of explanation, the film with high adhesion is named the first film A, and the film with low adhesion is named the second film B. The two substrates are named the first substrate C and the second substrate D, respectively. The first film A and the second film B have an adhesive layer on one side and no adhesive on the other side. The first substrate C and the second substrate D are rigid substrates, for example, made of metal. Both have multiple through holes. The first film A is bonded to one side of the first substrate C, and the second film B is bonded to one side of the second substrate D. Before transfer, material E is located inside the through-hole of the first substrate C, with one end bonded to the first film A and the other end extending out of the through-hole. During transfer, the second film B is at the bottom layer, with the second substrate D facing upwards. The first substrate C is placed over the upper surface of the second substrate D, allowing the lower end of material E to enter the through-hole of the second substrate D and bond with the second film B. After material E and the second film B are firmly bonded, a portion of the first film A is lifted from its edge. Then, the first film A is driven to move relative to the first substrate C below, gradually separating the two. During this process, the material simultaneously separates from the first film A and is transferred to the second film B. It should be noted that although the adhesive force of the first film A is greater than that of the second film B, when a portion of the first film A is lifted, it is easier for it to separate from material E than the second film B, thus enabling the transfer of material E to the second film B.

[0071] In related technologies, the film-tearing module includes two independently operating pre-tearing mechanisms and film-tearing mechanisms. For example, the pre-tearing mechanism first moves to the working position, so that the edge of the first film A is initially separated from the first substrate C. Then, the pre-tearing mechanism leaves the working position, and the film-tearing mechanism moves back to the working position, fixes the initially separated edge of the first film A, and then drives the first film A to completely separate from the first substrate C. To achieve the above purpose, both the pre-tearing mechanism and the film-tearing mechanism need to be equipped with a separate drive mechanism to drive them to move in the horizontal and vertical directions, which increases both the structural cost and the volume. At the same time, the movement of the pre-tearing mechanism and the film-tearing mechanism needs to be controlled separately, which increases the control difficulty. In addition, both the pre-tearing mechanism and the film-tearing mechanism need to move to the working position first and then reset, which consumes more time and reduces efficiency.

[0072] To address the aforementioned problems, the first embodiment of this invention proposes a film-tearing module 500, which reduces the number of drive mechanisms, thereby helping to lower costs, reduce equipment size and control complexity, and also improve efficiency. (Refer to...) Figures 2 to 5 The film-tearing module 500 of this embodiment includes a pre-tearing device 510, a first clamping device 520, a first driving device 530, a second driving device 540, and a first base 550. The pre-tearing device 510 cooperates with the first driving device 530 to perform a pre-tearing operation, and the first clamping device 520 cooperates with the second driving device 540 to perform a film-tearing operation. Furthermore, the film-tearing module 500 also includes a fifth driving device 580, which drives the overall movement of the aforementioned devices.

[0073] Because the first film A is tightly adhered to the first substrate C, directly driving the first film A to separate from the first substrate C is quite difficult. Therefore, the film-peeling module 500 is equipped with a pre-peeling device 510, which is used to separate a portion of the edge of the first film A from the first substrate C, thereby facilitating the subsequent formal separation operation. Specifically, refer to... Figure 4 , Figure 5 The pre-tear film device 510 includes a film-scraping component 511, which has a relatively sharp end. Under external force, the film-scraping component 511 can enter from the edge of the first film A between the first film A and the first substrate C, causing a localized lifting of the first film A. Figure 4 In the embodiment shown, the film scraping component 511 is a blade.

[0074] The first driving device 530 is connected to the first base 550 and is used to drive the film scraping component 511 to move, thereby causing the film scraping component 511 to switch between a first extended state and a first retracted state, as detailed below. Figure 4As shown, at this time, the film scraping component 511 is in the first extended state, located between the first clamping component 521 and the second clamping component 522 of the first clamping device 520, and the end of the film scraping component 511 extends relative to the first clamping device 520, thereby being able to contact the first film A, as shown. Figure 5 As shown, the film scraping component 511 is in the first retracted state at this time, with its end retracted relative to the first clamping device 520. At this time, the first clamping device 520 can clamp the first film A. In some specific embodiments, the film scraping component 511 moves in a straight line and switches between the first extended state and the first retracted state. Based on this, the first base 550 is provided with a slide rail, a slider, and other mechanisms. A connecting seat is connected to the slider. The film scraping component 511 is connected to the connecting seat. The first driving device 530 drives the connecting seat to move, thereby driving the film scraping component 511 to move. It should be noted that the first drive device 530 can directly drive the film-scraping component 511 to move. For example, the first drive device 530 can be a drive element with a retractable drive shaft, such as a cylinder, and the film-scraping component 511 or its mounting base is connected to the drive shaft. Alternatively, the first drive device 530 can indirectly drive the film-scraping component 511 to move. For example, the first drive device 530 can include a drive element with a rotatable drive shaft, such as a motor, and the rotation of the drive shaft is converted into linear movement of the film-scraping component 511 through transmission mechanisms such as a synchronous belt-synchronous pulley, a lead screw-lead screw seat, or a gear-rack. The driving methods of subsequent drive devices can be understood in the same way.

[0075] In some other embodiments, the film scraping component 511 is detachably connected to the first drive device 530, so that the film scraping component 511 can be replaced when it is damaged.

[0076] The first clamping device 520 is used to clamp a portion of the first film A that has separated from the first substrate C. Specifically, refer to... Figure 4 , Figure 5 The first clamping device 520 includes a first clamping component 521 and a second clamping component 522, which are disposed opposite to each other. At least one of the first clamping component 521 and the second clamping component 522 can be driven by the second driving device 540, thereby switching the first clamping device 520 between a first clamping state and a first open state. When the first clamping device 520 is in the first clamping state, it can clamp the first film A. In some other embodiments, it can also clamp the film scraper component 511. When the first clamping device 520 is in the first open state (e.g., ...), it can clamp the first film A. Figure 4 , Figure 5When in the state shown, it allows the first film A or the film scraper component 511 to enter between the first clamping component 521 and the second clamping component 522. It should be noted that the second driving device 540 is connected to the first base 550. When both the first clamping component 521 and the second clamping component 522 are driven by the second driving device 540, both are connected to the second driving device 540. When one of the first clamping component 521 and the second clamping component 522 is driven by the second driving device 540, one is connected to the second driving device 540, and the other is connected to the first base 550. It should also be noted that when both the first clamping component 521 and the second clamping component 522 are driven by the second driving device 540, the second driving device 540 can drive the first clamping component 521 and the second clamping component 522 to move synchronously using a single power element, or it can drive the first clamping component 521 and the second clamping component 522 to move separately using two power elements.

[0077] The fifth driving device 580 is connected to the first base 550 and is used to drive the first base 550 to move. Since the pre-tear film device 510, the first clamping device 520, the first driving device 530, and the second driving device 540 are all directly or indirectly connected to the first base 550, the pre-tear film device 510, the first clamping device 520, the first driving device 530, the second driving device 540 and the first base 550 can be driven as an integral module by the fifth driving device 580. In some specific embodiments, the fifth driving device 580 can drive the aforementioned integral module to move in the vertical direction. In other specific embodiments, the fifth driving device 580 can drive the aforementioned integral module to move in the horizontal direction. In still other specific embodiments, the fifth driving device 580 can drive the aforementioned integral module to move in both the horizontal and vertical directions.

[0078] Based on the above structure, the film-peeling module 500 of this embodiment is configured to perform the following operations:

[0079] Reference Figure 6 In step (b), when the first substrate C with the first film A attached is placed on the external carrier module 300 ( Figure 6(Not shown in the image), and when the film-scraping component 511 is in the first extended state and abuts against the edge of the first film A, relative movement occurs between the film-tearing module 500 and the carrier module 300, so that the film-scraping component 511 extends between the edge of the first film A and the first substrate C, and so that the edge of the first film A is located between the first clamping component 521 and the second clamping component 522. It should be noted that the relative movement between the film-tearing module 500 and the carrier module 300 referred to here includes the case where only the film-tearing module 500 or the carrier module 300 moves alone, as well as the case where the film-tearing module 500 and the carrier module 300 move together. Furthermore, the relative movement may include only horizontal movement, or it may include both horizontal and vertical movement. The horizontal and vertical movement may be performed entirely by one of the film-tearing module 500 and the carrier module 300, or it may be distributed among the film-tearing module 500 and the carrier module 300 to perform the movement together. It should also be noted that the phrase "so that the film scraping component 511 extends between the edge of the first film A and the first substrate C, and so that the edge of the first film A is located between the first clamping component 521 and the second clamping component 522" includes the following situations: 1. After the film scraping component 511 enters between the edge of the first film A and the first substrate C, the film tearing module 500 and the carrier module 300 continue to move directly in the same direction, so that the edge of the first film A enters between the first clamping component 521 and the second clamping component 522; 2. After the film scraping component 511 enters between the edge of the first film A and the first substrate C, the film tearing module 500 and the carrier module 300 first move in another direction, and then continue to move in the previous direction, so that the edge of the first film A enters between the first clamping component 521 and the second clamping component 522, for example... Figure 6 Steps (c) to (f) in the process.

[0080] Reference Figure 6 In step (f), when the edge of the first film A is located between the first clamping member 521 and the second clamping member 522, and the film scraping member 511 is in the first retracted state, the first clamping device 520 switches from the first open state to the first clamping state to clamp the edge of the first film A. In this way, the first clamping device 520 can fix the first film A.

[0081] Reference Figure 7 After the first clamping device 520 clamps the edge of the first film A, a relative movement occurs between the film-tearing module 500 and the carrier module 300, so that the first film A is completely separated from the first substrate C. Similarly, the relative movement between the film-tearing module 500 and the carrier module 300 here can be referred to... Figure 6 Understanding the relative motion between the two.

[0082] In summary, this embodiment achieves partial and complete detachment of the edge of the first film A by switching the film-scraping component 511 between the first extended state and the first retracted state, and by switching the first clamping device 520 between the first clamping state and the first open state. During this process, the pre-tear film device 510 and the first clamping device 520 do not need to be moved to the working position and reset separately, which can improve efficiency and simplify control. In addition, this embodiment integrates the pre-tear film device 510 and the first clamping device 520 into the first base 550 and drives them in a unified manner, which can simplify the structure and reduce costs.

[0083] Based on the first embodiment, in some embodiments of the present invention, reference is made to Figure 6 In steps (b) to (d), the aforementioned "relative movement between the film-tearing module 500 and the carrier module 300, so that the film-scraping component 511 extends into the space between the edge of the first film A and the first substrate C, and so that the edge of the first film A is located between the first clamping component 521 and the second clamping component 522" specifically refers to: a first horizontal movement between the film-tearing module 500 and the carrier module 300, so that the film-scraping component 511 extends into the space between the edge of the first film A and the first substrate C; a second vertical movement between the film-tearing module 500 and the carrier module 300, so that the film-scraping component 511 moves the edge of the first film A away from the first substrate C; and a third horizontal movement between the film-tearing module 500 and the carrier module 300, so that the edge of the first film A is located between the first clamping component 521 and the second clamping component 522. It should be noted that the first movement, second movement and third movement referred to in this embodiment all include the case where only the film-tearing module 500 or the carrier module 300 moves alone, or both move together.

[0084] When the distance between the edge of the first film A and the material E closest to that edge is small, if the film tearing module 500 and the carrier module 300 are from... Figure 6 If the relative movement continues directly in the same direction in the state of step (c), the film scraping component 511 may touch and damage the material E. Based on this, in this embodiment, after the film scraping component 511 extends into the first film A at a set distance, it first moves upward to be higher than the material E. Then the film tearing module 500 and the carrier module 300 move relative to each other in the previous direction. This allows the edge of the first film A to enter between the first clamping component 521 and the second clamping component 522, and also avoids the film scraping component 511 from damaging the material E.

[0085] Based on the above embodiments, referring to Figure 6In some specific embodiments, the carrier module 300 moves horizontally to perform a first movement, that is, the film scraping component 511 remains stationary during this process, while the carrier module 300 actively moves so that the film scraping component 511 extends below the edge of the first film A. Specifically to Figure 6 In steps (b) to (c) shown, the carrier module 300 moves to the right, causing the film-scraping component 511 to extend from the right edge of the first film A into the space between the first film A and the first substrate C. It should be noted that when the carrier module 300 can move horizontally, it can specifically move horizontally between the loading position and the film-tearing position. For example, at the loading position, it receives the first substrate C with the first film A bonded to it and the second substrate D with the second film B bonded to it, and then moves to the film-tearing position to cooperate with the film-tearing module 500 to tear the film. In other specific embodiments, it can specifically move horizontally between the unloading position and the film-tearing position. For example, after the carrier module 300 cooperates with the film-tearing module 500 to tear the film, the carrier module 300 moves to the unloading position, waiting for the transfer module to unload the second film B, which has already been transferred with material E.

[0086] Based on the above embodiments, referring to Figure 6 In some specific embodiments, the film-tearing module 500 moves vertically upward to perform a second movement, that is, the carrying module 300 remains stationary during this process, while the film-scraping component 511 moves actively to lift the edge of the first film A.

[0087] Based on the above embodiments, referring to Figure 6 In some specific embodiments, the carrier module 300 moves horizontally to perform a third movement, that is, the film scraping component 511 remains stationary during this process, while the carrier module 300 actively moves so that the edge of the first film A enters between the first clamping component 521 and the second clamping component 522. Specifically to Figure 6 In steps (e) to (f) shown, the carrier module 300 moves to the right, so that the right edge of the first membrane A extends between the first clamping member 521 and the second clamping member 522.

[0088] The above embodiments can also be combined. That is, the bearing module 300 moves horizontally to perform the first and third movements, and the film-tearing module 500 moves vertically upward to perform the second movement. In other words, in this embodiment, the horizontal movement is assigned to the bearing module 300, and the vertical movement is assigned to the film-tearing module 500. Accordingly, the bearing module 300 only needs to be equipped with a horizontal driving device, and the film-tearing module 500 only needs to be equipped with a vertical driving device (i.e., the fifth driving device 580). Compared with the scheme of a single driving device integrating horizontal and vertical driving functions, this embodiment can reduce the volume of a single driving device. At the same time, the driving device in this embodiment only needs to perform the movement control of a single driving device in the horizontal or vertical direction, which helps to reduce the control difficulty.

[0089] It should be noted that when the film-tearing module 500 can move vertically and the supporting module 300 can move horizontally, refer to... Figure 6 In step (a), the film-tearing module 500 is initially positioned above the movement trajectory of the carrier module 300, thus avoiding interference when the carrier module 300 moves. After the carrier module 300 moves to the film-tearing position, the film-tearing module 500 can move downward until the film-scraping component 511 abuts against the edge of the first film A.

[0090] Based on the above embodiments, referring to Figure 6 In steps (d) to (f), in some specific embodiments, the aforementioned "after the second movement occurs, a third movement occurs between the film-tearing module 500 and the carrier module 300 in the horizontal direction" specifically means that after the second movement occurs, the film-scraping component 511 first switches from the first extended state to the first retracted state, and then a third movement occurs between the film-tearing module 500 and the carrier module 300.

[0091] When the film-peeling module 500 is in Figure 6 In step (d), if the film-peeling module 500 and the carrier module 300 move relative to each other directly along the previous direction, the film-scraping component 511 will cause significant deformation along the edge of the first film A. This could lead to a risk of the first film A breaking, and also cause the portion of the first film A with the material E adhering to it to separate prematurely from the first substrate C. Because the vertical force applied by the film-scraping component 511 to the first film A is relatively large during this process, and the first film A has greater adhesion, therefore... Figure 7Compared to the method of separating along the horizontal direction, it is more likely that material E will not detach from the first film A, resulting in material E residue. Based on this, in this embodiment, after the film scraping component 511 moves the edge of the first film A further away from the first substrate C, the film scraping component 511 first retracts, and then a third movement occurs between the film tearing module 500 and the carrier module 300 so that the edge of the first film A enters between the first clamping component 521 and the second clamping component 522. This can improve the problem of excessive deformation of the edge of the first film A and the transfer and residue of material E on the first film A.

[0092] Based on the first embodiment, referring to Figure 6 In steps (a) to (b) of the present invention, in some embodiments, when the film scraping component 511 is in the first extended state and abuts against the edge of the first film A, the first clamping device 520 is in the first clamping state to clamp the film scraping component 511. The thickness of the first film A is typically small. To facilitate accurate abutment of the film scraping component 511 against the edge of the first film A, the thickness of the film scraping component 511 is also set to be small, and it is in a cantilever state with one end fixed and the other end suspended. Therefore, there is a risk of swaying or bending, affecting the film scraping effect. Based on this, in this embodiment, by clamping the film scraping component 511 with the first clamping device 520, the length of the cantilever portion can be reduced, thereby reducing the swaying or bending of the film scraping component 511. It should be noted that in other specific embodiments, referring to... Figure 6 In step (a), the initial state of the first clamping device 520 is the first open state, and the initial state of the film scraping component 511 is the first retracted state. Therefore, in this embodiment, from step (a) to step (b), the film scraping component 511 needs to switch from the first retracted state to the first extended state, and the first clamping device 520 needs to switch from the first open state to the first clamping state.

[0093] In this embodiment, refer to Figure 6 In steps (c) to (e), after the film scraping component 511 extends between the edge of the first film A and the first substrate C, the first clamping device 520 switches from the first clamping state to the first open state, thereby facilitating the subsequent entry of the edge of the first film A between the first clamping component 521 and the second clamping component 522. It should be noted that when a second vertical movement occurs between the carrier module 300 and the film tearing module 500, the first clamping device 520 switches from the first clamping state to the first open state after the second movement occurs. For example, after the film scraping component 511 moves upward to perform the second movement, the first clamping device 520 switches from the first clamping state to the first open state.

[0094] Based on the first embodiment, referring to Figure 4 , Figure 5The first clamping component 521 is connected to the second driving device 540, and the second clamping component 522 is connected to the first base 550. The first clamping component 521 is located above the second clamping component 522. That is, in this embodiment, the second clamping component 522 is fixed relative to the first base 550, while the first clamping component 521 can move relative to the first base 550, thereby realizing the state switching of the first clamping device 520.

[0095] In this embodiment, the second clamping member 522 has a guide surface 5221 on the side facing the first clamping member 521. The height of the guide surface 5221 gradually decreases along the direction from the fixed end to the free end of the second clamping part, thereby facilitating the entry of the raised edge of the first membrane A into the first clamping member 521 and the second clamping member 522. In some specific embodiments, the guide surface 5221 is a slope or an arc surface.

[0096] Based on the first embodiment, referring to Figure 4 , Figure 5 The side of the second clamping component 522 facing away from the first clamping component 521 is a horizontal plane, which is adapted to the horizontally placed first substrate C, so as to avoid interference between the second clamping component 522 and the first substrate C when the carrier module 300 and the film-tearing module 500 move relative to each other in the horizontal direction.

[0097] Based on the first embodiment, referring to Figure 7 In steps (a) to (d), in some embodiments of the present invention, the aforementioned "relative movement between the film-tearing module 500 and the carrier module 300 to separate the first film A from the first substrate C" specifically refers to: the carrier module 300 moving in the horizontal direction and the film-tearing module 500 moving synchronously in the vertical direction to separate the first film A from the first substrate C.

[0098] In this embodiment, the separation of the first membrane A is achieved through a combination of horizontal and vertical movements. The vertical movement is distributed to the film-tearing module 500, and the horizontal movement is distributed to the support module 300. Therefore, it also achieves the aforementioned effects of reducing the size of a single drive unit and simplifying control. Furthermore, if the film-tearing module 500 and the support module 300 only achieve the separation of the first membrane A through relative horizontal movement—for example, when the film-tearing module 500 is fixed while the support module 300 moves horizontally—the movement distance of the support module 300 after the first membrane A is completely separated is relatively long (approximately equal to the sum of the length of the support module in the movement direction and the length of the first membrane A in the movement direction). This would limit the application of the film-tearing module 500 in space-constrained devices. Therefore, this embodiment uses the vertical movement of the film-tearing module 500, causing the separated first membrane A to change from a horizontal extension to a vertical extension, which shortens the movement distance of the support module 300. For example… Figure 7The moving distance of the middle support module 300 is approximately equal to the length of the first membrane A in the moving direction, thereby increasing the application range of the membrane tearing module 500.

[0099] Based on the above embodiments, referring to Figure 2 , Figure 3 The film-tearing module 500 also includes an auxiliary device 560 and a third driving device 570. The auxiliary device 560 includes a first auxiliary roller 561, which is connected to the third driving device 570 and can be driven to move by the third driving device 570. In some specific embodiments, the third driving device 570 can drive the first auxiliary roller 561 to move in the horizontal direction.

[0100] Reference Figure 7 In steps (a) to (c), the aforementioned "relative movement between the film-tearing module 500 and the carrier module 300 to separate the first film A from the first substrate C" specifically refers to the following: After relative movement occurs between the film-tearing module 500 and the carrier module 300, causing a portion of the first film A to separate from the first substrate C (e.g., after a quarter length of the first film A separates from the first substrate C), the third driving device 570 drives the first auxiliary roller 561 to move until it abuts against the first film A (e.g., as shown in step (b)). Furthermore, along the direction of horizontal movement of the carrier module 300, the abutment position of the first auxiliary roller 561 against the first film A is located in front of the first film A. Thus, even if the film-tearing module 500 continues to move upward, the angle between the first film A and the first substrate C between the first auxiliary roller 561 and the first substrate C will not change. After the first auxiliary roller 561 abuts against the first film A, relative movement occurs again between the film-tearing module 500 and the carrier module 300 to completely detach the first film A from the first substrate C.

[0101] As mentioned above, if the vertical component of the force applied by the film-tearing module 500 to the first film A is large, material E is likely to remain on the first film A. Furthermore, as the film-tearing module 500 moves upward, the angle between the separated portion of the first film A and the first substrate C will inevitably increase, and the vertical component of the force applied by the film-tearing module 500 to the first film A will also increase, which is detrimental to the transfer of material E. Therefore, this embodiment, by setting the first auxiliary roller 561 to abut against the first film A, ensures that the first film A between the first auxiliary roller 561 and the first substrate C maintains a suitable angle for material E separation, thereby reducing or avoiding material E residue.

[0102] It should be noted that in some specific embodiments, the first auxiliary roller 561 can rotate around its own axis to reduce the frictional force during the sliding process of the first film A relative to the first auxiliary roller 561.

[0103] When the film-peeling module 500 also includes an auxiliary device 560, refer to Figure 7 In step (d) of the present invention, in some embodiments, the auxiliary device 560 further includes a second auxiliary roller 562, and the film-tearing module 500 further includes a fourth driving device. The second auxiliary roller 562 is connected to the fourth driving device and can be driven to move by the fourth driving device. In some specific embodiments, the fourth driving device can drive the second auxiliary roller 562 to move in the horizontal direction.

[0104] In this embodiment, after the first membrane A is completely separated from the first substrate C, the fourth driving device drives the second auxiliary roller 562 to move until it comes into contact with the first membrane A, so as to cooperate with the first auxiliary roller 561 to clamp the first membrane A together, so as to prevent the first membrane A from shaking after separation, and to facilitate the collection module 100 and other modules to fix the first membrane A.

[0105] Based on the first embodiment, referring to Figure 3 The film-tearing module 500 also includes a pressure roller 590. Along the direction of movement of the carrier module 300 from the feeding position to the film-tearing position, the pressure roller 590 is located behind the pre-tear film device 510 and the first clamping device 520. That is, before the carrier module 300 carrying the first film A and the second film B moves to the film-tearing position, the pressure roller 590 will first roll the first film A, so that the material E can better adhere to the second film B, thereby ensuring the transfer effect of the material E.

[0106] The second embodiment of the present invention provides a material transfer device for transferring material E from a first film A bonded to a first substrate C to a second film B bonded to a second substrate D. The specific transfer principle can be found in [reference needed]. Figure 1 As understood in the foregoing embodiments.

[0107] Reference Figure 8 The material transfer device of this embodiment includes a feeding module 200, a carrying module 300, a transfer module 400, a film-tearing module 500, and a collection module 100 of the aforementioned embodiments. The feeding module 200 is used to supply a first film A with material E bonded to it and an empty second film B. The carrying module 300 is used to carry the first film A bonded to the first substrate C and the second film B bonded to the second substrate D. The transfer module 400 is used to transfer the first film A and the second film B supplied by the feeding module 200 to the carrying module 300, so that the second film B is bonded to the material E on the first film A. The film-tearing module 500 is used to drive the first film A to separate from the material E. The collection module 100 is used to collect the first film A after it has been separated from the material E.

[0108] Specifically, the feeding module 200 has at least a first storage area and a second storage area. The first storage area stores a first film A bonded with material E. Specifically, the first film A uses a first substrate C as a carrier. Therefore, the first film A, the first substrate C, and the corresponding material are stored as a material unit. Similarly, the second storage area stores a second film B, which uses a second substrate D as a carrier. Therefore, the second film B and the second substrate D are stored as a material unit. In some specific embodiments, the feeding module 200 is also provided with a material output mechanism. The material output mechanism is used to remove the stored material unit from the corresponding storage area and transfer it to a set feeding position. The material output mechanism can be a conveyor belt capable of transporting material units, or a robotic arm capable of clamping material units and moving them horizontally.

[0109] The carrier module 300 is used to carry the first membrane A and the second membrane B, as shown in the figure. Figure 1 Specifically, the second film B and the second substrate D are placed directly on the carrier module 300 with the second film B facing down and the second substrate D facing up, while the first film A and the first substrate C are placed on the second substrate D with the first film A facing up and the first substrate C facing down. This allows the second film B to be bonded to the material E. In some specific embodiments, the carrier module 300 can move horizontally to carry the material unit transferred by the transfer module 400 at the loading position and move the material unit to the film-tearing position for film tearing.

[0110] The transfer module 400 can be a robotic arm that can move in space, which transfers the material units output by the feeding module 200 to the carrier module 300. Specifically, it transfers the material units in the following order: first, the second film B and the second substrate D are transferred to the carrier module 300, and then the first film A and the first substrate C are transferred to the second substrate D.

[0111] As mentioned earlier, after the transfer of material E is completed, a second film B with material E adhered to it and a blank first film A will be obtained. The second film B with material E adhered to it will be further transported to the next work station, where a robot will separate material E from the second film B. The blank first film A will be collected as waste. However, due to the high viscosity of the first film A, it is easy to stick to the first clamping device 520 of the film tearing module 500. Related technologies use anti-stick materials to prevent the first film A from sticking. For example, the first clamping component 521 and the second clamping component 522 are made of anti-stick material. When the first film A is completely separated from the material E, the first clamping device 520 opens, allowing the first film A to fall automatically under the action of gravity. However, the anti-stick material cannot completely eliminate the sticking problem. There is still a problem that the first film A cannot automatically detach from the first clamping device 520. At this time, manual cleaning is required, which increases labor costs and affects production efficiency.

[0112] Based on the above, and referring to the second embodiment... Figures 9 to 11 The collection module 100 includes a second clamping device 110, a sixth driving device 120, a film removal device 130, and a collection container (not shown). The sixth driving device 120 is used to drive the second clamping device 110 to close or open. When the second clamping device 110 is closed, it can clamp the first film A, thereby separating the film removal module from the first film A. When the second clamping device 110 is opened, the first film A will adhere to a specific part of the second clamping device 110. Then, the film removal device 130, which can prevent adhesion, will detach the first film A from the second clamping device 110. In this way, the problem of the first film A adhering to the film removal module can be effectively improved.

[0113] Specifically, the second clamping device 110 includes a third clamping member 111 and a fourth clamping member 112 disposed opposite to each other. The third clamping member 111 has a first surface 1111 for clamping the first film A, and the fourth clamping member 112 has a second surface 1121 for clamping the first film A. In other words, the first surface 1111 and the second surface 1121 can work together to clamp the first film A. The third clamping member 111 and the fourth clamping member 112 can be, for example... Figure 10 , Figure 11 The clamping seat shown has a first surface 1111 and a second surface 1121, which are the vertical sidewalls of the clamping seat facing the opposite clamping seat. In this embodiment, the second surface 1121 is an anti-stick surface, meaning that the first film A cannot or is not easily adhered to the second surface 1121. Conversely, the first surface 1111 is a normal surface, meaning that the first film A can or is more easily adhered to the second surface 1121. In other words, when both the first surface 1111 and the second surface 1121 are adhered to the first film A, the second surface 1121 is more likely to detach from the first film A. It should be noted that in some specific embodiments, the fourth clamping component 112 is entirely made of an anti-stick material. In other specific embodiments, the fourth clamping component 112 has an anti-stick coating, and the surface coated with the anti-stick coating is the second surface 1121. In other specific embodiments, the fourth clamping component 112 is a split structure, with one part made of ordinary material and the other part made of anti-stick material. The part made of anti-stick material has the second surface 1121. The aforementioned anti-stick material or anti-stick coating can be Teflon.

[0114] The sixth driving device 120 is connected to at least one of the third clamping member 111 and the fourth clamping member 112, and is used to drive relative movement between the third clamping member 111 and the fourth clamping member 112, so that the second clamping device 110 switches between a second clamping state and a second open state. In some embodiments, the third clamping member 111 moves while the fourth clamping member 112 is stationary; in other embodiments, the fourth clamping member 112 moves while the third clamping member 111 is stationary; in still other embodiments, both the third clamping member 111 and the fourth clamping member 112 are movable. Accordingly, the sixth driving device 120 may include one or more driving elements.

[0115] The film removal device 130 is connected to the third clamping component 111. The film removal device 130 can actively drive the first film A to detach from the third clamping component 111. Compared with the passive detachment method relying on gravity, it can greatly reduce the situation where the first film A remains in the third clamping component 111.

[0116] A collection container (not shown) is disposed below the second clamping device 110 for collecting the first membrane A separated from the third clamping member 111. In some embodiments, a membrane inlet is provided at the top of the collection container, and the first membrane A separated from the third clamping member 111 falls directly into the collection container. In other embodiments, the collection module 100 further includes a guiding device that is connected to the collection container and has a membrane inlet, through which the first membrane A separated from the third clamping member 111 falls and is then guided to the collection container.

[0117] Based on the aforementioned structure, in this embodiment, the collection module 100 is configured such that: after the first membrane A is completely separated from the material E, the second clamping device 110 clamps the first membrane A, allowing the external film-tearing module to separate from the first membrane A, thus preventing the first membrane A from remaining on the film-tearing module; subsequently, the second clamping device 110 holding the first membrane A switches from the second clamping state to the second open state. Since the second surface 1121 on the fourth clamping component 112 that contacts the first membrane A is an anti-stick surface, while the first surface 1111 on the third clamping component 111 that contacts the first membrane A is a normal surface, the first membrane A separates from the fourth clamping component 112 and adheres to the first surface 1111 of the third clamping component 111, thereby achieving directional adhesion of the first membrane A; finally, after the first membrane A adheres to the third clamping component 111, the film-removing device 130 drives the first membrane A to separate from the third clamping component 111, and the first membrane A falls into the collection container. In summary, this embodiment uses the third clamping component 111 and the fourth clamping component 112 to clamp the first film A, thereby facilitating the complete separation of the external film-tearing module from the first film A and preventing the first film A from remaining in the film-tearing module. By using the third clamping component 111 and the fourth clamping component 112, which are respectively provided with the first surface 1111 and the second surface 1121, the first film A can be oriented and bonded. Combined with the active driving of the film-removing device 130 to detach the first film A from the third clamping component 111, the first film A can also be prevented from remaining in the third clamping component 111. In this way, the time for manual downtime cleaning can be reduced, which helps to reduce labor costs and improve efficiency.

[0118] Based on the first embodiment, another embodiment of the demolding device 130 will be described below. In this embodiment, the demolding device 130 and the third clamping member 111 are capable of relative movement. Refer to Figure 10 and Figure 11 The demolding device 130 of this embodiment includes an ejector component 131, which has a third surface 1311 for contacting the first film A. The third surface 1311 is an anti-stick surface. It should be noted that the anti-stick surface here can be understood with reference to the above.

[0119] In this embodiment, the ejector component 131 and the third clamping component 111 can move relative to each other, so that the ejector component 131 can switch between a second extended state and a second retracted state. When the ejector component 131 is in the second extended state, it extends relative to the first surface 1111, and when the ejector component 131 is in the second retracted state, it retracts relative to the first surface 1111. In this way, when the ejector component 131 is in the second retracted state, it will not prevent the first film A from adhering to the first surface 1111 of the third clamping component 111. When the ejector component 131 is in the second extended state, it can hold the first film A so that the first film A can detach from the first surface 1111. Since the surface in contact between the ejector component 131 and the first film A is an anti-stick surface, and the force between the two is small and the contact time is short when the ejector component 131 ejects the first film A, the first film A will not stick to the ejector component 131. After the first film A is completely separated from the first surface 1111, it can fall downward.

[0120] Based on the above structure, in this embodiment, the collecting module 100 is configured such that when the second clamping device 110 is in the second clamping state, the ejector component 131 is in the second retracted state, allowing the first membrane A to contact the first surface 1111. When the first membrane A adheres to the third clamping component 111, the ejector component 131 is in the second extended state, which can drive the first membrane A to separate from the third clamping component 111. It should be noted that the "ejector component 131 in the second extended state" mentioned here can be either the ejector component 131 actively moving to be in the second extended state, or the third clamping component 111 actively moving to be in the second extended state.

[0121] In some specific embodiments, reference is made to Figure 11 The ejector component 131 specifically includes ejector rods 1312 and a first mounting base 1313. Multiple ejector rods 1312 are mounted on the same side of the first mounting base 1313. The end face of each ejector rod 1312 away from the first mounting base 1313 is the aforementioned third surface 1311. Each ejector rod 1312 protrudes from the first mounting base 1313 at the same height, making each third surface 1311 flush. Correspondingly, the third clamping component 111 is provided with multiple through holes. One end of each through hole extends to the first surface 1111, and the other end extends to another surface opposite to the first surface 1111. When the ejector component 131 is in the second extended state, the ejector rods 1312 pass through the corresponding through holes, and the ends of the ejector rods 1312 protrude from the first surface 1111. When the ejector component 131 is in the second retracted state, the ends of the ejector rods 1312 retract into the corresponding through holes, or all the ejector rods 1312 disengage from the corresponding through holes.

[0122] In this embodiment, by setting multiple push rods 1312 to disengage the first membrane A from the third clamping member 111, the contact range between the ejector member 131 and the first membrane A can be increased, while the contact area between the ejector member 131 and the first membrane A can be reduced. This further ensures that the first membrane A can disengage from the third clamping member 111 without sticking to the ejector member 131.

[0123] When the demolding device 130 includes an ejector component 131, in some specific embodiments, the third clamping component 111 can move actively, as shown in the reference. Figure 10 , Figure 11 The sixth driving device 120 includes a first driving element 121, and a third clamping member 111 is connected to the first driving element 121 and can be driven by the first driving element 121 to switch between a first position and a second position. Specifically, the sixth driving device 120 also includes a second mounting base 123, to which the first driving element 121 is fixed.

[0124] In this embodiment, the fourth clamping component 112 can also move actively. That is, both the third clamping component 111 and the fourth clamping component 112 can move to realize the switching of the second clamping device 110 between the second clamping state and the second open state. Specifically, refer to... Figure 10 , Figure 11 The sixth driving device 120 also includes a second driving element 122. The fourth clamping member 112 is connected to the second driving element 122 and can be driven by the second driving element 122 to switch between the third position and the fourth position. The second driving element 122 can also be understood with reference to the first driving element 121.

[0125] Based on the above structure, in this embodiment, the clamping component 110 achieves state switching in the following manner: when the third clamping component 111 is in the first position (e.g., Figure 10 The third clamping member 111 is in the third position, and the fourth clamping member 112 is in the third position (e.g., the position of the third clamping member 111). Figure 10 When the fourth clamping member 112 is in its position, the two are separated by a certain distance, the second clamping device 110 is in the second open state, and at this time the ejecting member 131 extends from the first surface 1111 of the third clamping member 111 and is in the second extended state. When the third clamping member 111 is in the second position (for example, the third clamping member 111 extends from the first surface 1111 of the third clamping member 111), the second clamping device 110 is in the second open state. Figure 10 The position of the clamping component 112 is moved a certain distance to the left, and the fourth clamping component 112 is in the fourth position (for example, the fourth clamping component 112 is in the fourth position). Figure 10When the position of the device moves a certain distance to the right, the second clamping device 110 is in the second clamping state, and at this time the ejector 131 retracts from the first surface 1111 of the third clamping device 111 and is in the second retracted state.

[0126] It should be noted that in the aforementioned embodiments, the third clamping member 111 is provided with a first surface 1111, and the ejecting member 131 is provided with a third surface 1311. Therefore, the first membrane A is first adhered to the third clamping member 111, and then driven to separate by the ejecting member 131. In other embodiments, the functions of the third clamping member 111 and the ejecting member 131 in the aforementioned embodiments can also be interchanged, that is... Figure 10 , Figure 11 Component 111 is used as an ejection mechanism, while... Figure 10 , Figure 11 Component 131 is used as a clamping mechanism. Specifically, component 111 has a third surface 1311 and a first surface 1111. The first film A is first adhered to component 131 and then driven to separate by component 111. When component 131 includes the push rod 1312 and the first mounting base 1313 as described in the previous embodiment, the end face of the push rod 1312 away from the first mounting base 1313 is the first surface 1111. Based on this, component 131 can be fixedly set while component 111 can move relative to component 131, or component 111 can be fixedly set while component 131 can move relative to component 111.
