Description

Stripping apparatus

Technical Field

The present application relates to the field of component carriers, in particular to a stripping apparatus for component carriers.

Background

This section provides background information related to the application, but such information does not necessarily constitute prior art.

In the manufacture of component carriers, such as circuit boards, the surface of the unprocessed component carrier is typically covered with films of different functions, such as photosensitive films, dielectric films, solder resist films, etc., which are typically required to be covered with protective films. Therefore, the surface of the component carrier needs to be processed after the protective film is removed.

In recent years, with the rapid development of component carrier manufacturing automation technology, traditional manual film tearing operation modes are gradually replaced by automatic component carrier film tearing devices. The component carrier film tearing device is used as a link of a component carrier automatic production line, after the component carrier is conveyed to a film lifting table through the component carrier conveying device, a film lifting mechanism is contacted with the surface of the component carrier to lift up a film, so that the separation of the film and the component carrier is realized. The application of the component bearing piece film tearing device greatly improves the production efficiency, effectively reduces the pollution source in the manufacturing process of the component bearing piece and ensures the production quality of the component bearing piece.

However, when the component carrier and other semiconductor package products or technologies need to be single-sided patterned, first, the film on one side of the component carrier is peeled off, and then the side from which the film is peeled off is subjected to ultraviolet laser treatment. Therefore, the film tearing device needs to have a function of peeling the film on the single side. However, in the conventional film tearing device, most of the film tearing devices can only conduct simultaneous double-sided peeling, and the requirement of single-sided film peeling cannot be met. The single-sided tear film requires manual stripping by a worker.

The related art discloses a film tearing apparatus that achieves an effect of sequentially peeling films of an upper side portion and a lower side portion of a component carrier by employing an initial peeling device and an integral peeling device. The film tearing apparatus may also be used to peel film on only one side of a component carrier. However, in this technique, peeling the film from the component carrier requires passing the film through the initial peeling device and the integral peeling device in order, and requires changing the direction of movement of the strongly adhesive roller, the weakly adhesive roller, and the conveying roller, which would result in a complicated operation. In addition, in the initial peeling apparatus, the strongly adhesive roller needs to be driven by the conveying roller driving member carrier, and in the integral peeling apparatus, the weakly adhesive roller drives the member carrier to move the conveying roller. Therefore, the respective rollers cannot be independently operated, and the operation flexibility is weak.

Thus, there is a need for a more efficient stripping apparatus that can achieve both single-sided and double-sided film stripping.

According to the peeling apparatus of the exemplary embodiment of the present application, two roughening wheels are provided on opposite sides of the component carrier to be treated to roughen the film disposed on the surface of the component carrier, thereby increasing the surface roughness of at least a portion of the film subjected to the roughening treatment. During the peeling of the film, the adhesive tape is attached to a portion (e.g., an edge portion) of the film, and the adhesive tape and the portion of the film are lifted together, and by roughening the surface of the film, the adhesion between the adhesive tape and the roughened portion of the film is significantly improved.

In the peeling apparatus provided by the present application, since the first smooth wheel drive, the first roughening wheel drive, the second smooth wheel drive, and the second roughening wheel drive are independently operated with respect to each other, the first optical pulley, the first roughening wheel, the second optical pulley, and the second roughening wheel can be individually actuated so that a user can select the corresponding wheels as needed to process the film attached to the surface of the component carrier, the operation is simpler and more flexible.

In some embodiments, the first light wheel and the first roughening wheel may be disposed opposite in a vertical direction, and the first light wheel and the first roughening wheel simultaneously move in the vertical direction toward the component carrier under the influence of the associated drive to bring the first roughening wheel into contact with at least a portion of the film attached to one of the upper and lower surfaces of the component carrier; and/or the second optical pulley and the second roughening wheel are oppositely disposed in the vertical direction, and the second optical pulley and the second roughening wheel are simultaneously moved in the vertical direction toward the component carrier by the associated drive so as to bring the second roughening wheel into contact with at least a portion of the film attached to the other one of the upper surface and the lower surface of the component carrier.

In some embodiments, the first smooth wheel drive, the first rough wheel drive, the second smooth wheel drive, and the second rough wheel drive are linear motors. Optionally, the first smooth wheel drive, the first roughened wheel drive, the second smooth wheel drive, and the second roughened wheel drive comprise pistons. In some alternative embodiments, the first smooth wheel drive, the first rough wheel drive, the second smooth wheel drive, and the second rough wheel drive comprise pistons actuated by compressed air.

In some embodiments, the roughening device may include a plurality of support structures supporting the first light wheel, the first roughening wheel, the second light wheel, and the second roughening wheel, respectively, each of the first smooth wheel drive, the first roughening wheel drive, the second smooth wheel drive, and the second roughening wheel drive being disposed on a side of the support structure of the respective wheel facing away from the wheel.

The support of the respective wheel and the respective wheel drive by the support structure enables the roughening device to remain relatively stable with respect to the component carrier to be treated during movement, further ensuring that the film is roughened in a desired manner.

In some embodiments, each support structure may include a support plate and an intermediate connector by means of which the support plate is connected, each intermediate connector may be connected with a respective one of the first light wheel, the first roughening wheel, the second light wheel, and the second roughening wheel.

In some embodiments, each of the first roughening wheel and the second roughening wheel may include a roughening portion on the outer circumferential surface that roughens the film, and the roughening portion may include a plurality of grooves or teeth extending helically in the circumferential direction.

In some embodiments, each of the first roughening wheel and the second roughening wheel may include a roughening portion on the outer circumferential surface that roughens the film, and the roughening portion may include a plurality of protrusions extending in the circumferential direction or the axial direction on the outer circumferential surface; and/or the roughened portion may include a plurality of recessed portions extending in the circumferential direction or the axial direction on the outer circumferential surface.

By providing the roughening wheel angle adjustment portion, the corresponding roughening wheel can be brought into contact with the film at an intended angle. Therefore, the size and the shape of the part, which is contacted with the film, of the corresponding coarsening wheel can be adjusted according to actual needs, so that the operation is more flexible.

In the context of this document, the term "component carrier" may particularly denote any support structure capable of accommodating one or more components on and/or in the component carrier to provide mechanical support and/or electrical connection. In other words, the component carrier may be configured as a mechanical and/or electrical carrier for the component.

Next, exemplary embodiments of the peeling apparatus according to the present application will be described in detail with reference to the accompanying drawings. The peeling apparatus of the present application may be used to peel a film (e.g., a film layer) attached to an upper surface and/or a lower surface of a component carrier (e.g., a printed circuit board), and the roughening device in the peeling apparatus of the present application is used to pretreat a portion of the film to achieve smooth and efficient peeling of the film. For clarity and conciseness of description, a conveying direction in which the component carriers are conveyed is indicated by an arrow a, a direction perpendicular to the conveying direction a is a vertical direction Y, and a direction perpendicular to both the conveying direction a and the vertical direction Y is a lateral direction X.

Fig. 1 is an overall schematic diagram of a peeling apparatus 1 according to an exemplary embodiment of the present application. In some exemplary embodiments, referring to fig. 1, the peeling apparatus 1 includes a conveying device 10 that conveys a component carrier 60 in a conveying direction a, a roughening device 20, a driving device that is connected to the roughening device 20 and drives the roughening device 20, and an edge lifting device 40 that includes an adhesive tape.

In some exemplary embodiments, edge lift device 40 is disposed downstream of the roughening device along conveying direction a, edge lift device 40 being configured to: in the case where a part of the edge portion of the film is roughened by the roughening device 20, the adhesive tape is bonded to a part of the roughened edge portion of the film and lifted by a predetermined distance in the vertical direction Y.

In some exemplary embodiments, roughening device 20 roughens a portion of a film attached on a surface of component carrier 60, the roughening device including a first roughening wheel 202, a second roughening wheel 204, a first optical pulley 201, and a second optical pulley 203.

In some exemplary embodiments, the first and second optical pulleys 201 and 203 are disposed on opposite sides of the component carrier 60 to be processed, respectively, and the first and second roughening wheels 202 and 204 are disposed on opposite sides of the component carrier 60 to be processed, respectively.

In some exemplary embodiments, one of the first roughening wheel 202 and the second roughening wheel 204 is disposed opposite the first optical pulley 201 in a vertical direction Y perpendicular to the conveying direction a of the component carrier 60; the other of the first roughening wheel 202 and the second roughening wheel 204 is disposed opposite to the second optical pulley 203 in the vertical direction Y, and the first roughening wheel 202 and the second roughening wheel 204 are spaced apart from each other in the lateral direction X perpendicular to both the conveying direction a and the vertical direction Y.

Fig. 2 is a perspective view of roughening apparatus 20 according to an exemplary embodiment of the present application, in which first optical pulley 201 is disposed opposite first roughening wheel 202 in vertical direction Y, and second optical pulley 203 is disposed opposite second roughening wheel 204 in vertical direction Y, and first roughening wheel 202 and second roughening wheel 204 are spaced apart from each other in lateral direction X, in the exemplary embodiment shown in fig. 2.

In some exemplary embodiments, the drives include a first drive 30 (also driven vertically) that moves roughening device 20 in vertical direction Y and a second drive 50 (also driven laterally) that reciprocates roughening device 20 in lateral direction X on the surface of component carrier 60.

Referring to fig. 3 and 4, the first driving device 30 includes a first smooth wheel driver 31 connected to the first optical pulley 201 and driving the first optical pulley 201, a first rough wheel driver 32 connected to the first rough wheel 202 and driving the first rough wheel 202, a second smooth wheel driver 33 connected to the second optical pulley 203 and driving the second optical pulley 203, and a second rough wheel driver 34 connected to the second rough wheel 204 and driving the second rough wheel 204. In one exemplary embodiment, the first smooth wheel drive 31, the first rough wheel drive 32, the second smooth wheel drive 33, and the second rough wheel drive 34 are independently operated with respect to one another.

In some exemplary embodiments, the first optical pulley 201 and the first roughening wheel 202 are oppositely disposed in the vertical direction Y, and the first optical pulley 201 and the first roughening wheel 202 are simultaneously moved in the vertical direction Y toward the component carrier 60 by the associated drive so as to bring the first roughening wheel 202 into contact with at least a portion of the film attached to one of the upper surface 61 and the lower surface 62 of the component carrier 60; and/or the second optical pulley 203 and the second roughening wheel 204 are oppositely disposed in the vertical direction Y, and the second optical pulley 203 and the second roughening wheel 204 are simultaneously moved in the vertical direction Y towards the component carrier 60 by an associated drive to bring the second roughening wheel 204 into contact with at least a portion of the film attached on the other one of the upper surface 61 and the lower surface 62 of the component carrier 60.

In some alternative embodiments, the first driving device includes a first driving member connected to and driving the first optical wheel and the first roughening wheel simultaneously, and a second driving member connected to and driving the second optical wheel and the second roughening wheel simultaneously.

In some examples, the first light wheel and the first roughening wheel are disposed opposite in a vertical direction, and the second light wheel and the second roughening wheel are disposed opposite in a vertical direction. Under the condition that the first driving device drives the roughening device, the first driving piece can drive the first optical pulley and the first roughening wheel simultaneously, so that the first optical pulley and the first roughening wheel move towards the upper surface and the lower surface of the component carrier simultaneously until contacting the upper surface and the lower surface of the component carrier. Similarly, the second driving member may also drive the second optical wheel and the second roughening wheel simultaneously such that the second optical wheel and the second roughening wheel move toward the component carrier simultaneously until contacting the upper and lower surfaces of the component carrier. With this configuration, when it is necessary to roughen only the film attached to one surface of the component carrier, it is necessary to actuate only the first or second driving member to operate the first or second optical pulleys and the second roughening wheel. In this way, only one of the first and second drivers need be actuated during the single-sided peel. During double-sided peeling, both of the first driving member and the second driving member need to be driven. Thus, the number of drives that need to be actuated during a single-sided stripping operation is reduced, thereby saving the power required during operation.

In some exemplary embodiments, the first roughening wheel and the second roughening wheel may be disposed opposite in a vertical direction, and the first optical pulley and the second smooth wheel may be disposed opposite in a vertical direction. The first roughening wheel and the second roughening wheel may be independently controlled. In the case where it is necessary to peel off the films on both the upper surface and the lower surface of the component carrier, one of the first roughening wheel and the second roughening wheel may be driven by a first driving device (vertical driving device) to be in contact with at least a portion of the film attached to the upper surface of the component carrier, and the other of the first roughening wheel and the second roughening wheel may be driven by the first driving device to be in contact with the film attached to the lower surface of the component carrier. In addition, when the roughening means is moved on the surface of the component carrier in the lateral direction by the second driving means (lateral driving means), the purpose of roughening the film attached to both the upper surface and the lower surface of the component carrier can be achieved.

It should be understood that the first driving means may drive only the first roughening wheel or only the second roughening wheel depending on the specific situation of the film intended to be peeled off of the component carrier.

By adopting the roughening device provided by the stripping equipment provided by the application, the corresponding roughening wheel can be selected for roughening according to the actual processing requirement of the component bearing piece to be processed, so that the roughening process can be flexibly set, and different processing requirements can be met.

In some exemplary embodiments, each of the first smooth wheel drive 31, the first rough wheel drive 32, the second smooth wheel drive 33, and the second rough wheel drive 34 is a linear motor, optionally including a piston.

In some exemplary embodiments, each of the first smooth wheel drive, the first rough wheel drive, the second smooth wheel drive, and the second rough wheel drive may comprise a screw drive, a rack gear system, or a slider drive. It should be understood that the driving member for roughening device of the present application is not limited to the exemplary driving member described herein, and may be selected according to the actual situation.

In some exemplary embodiments, referring to fig. 4, roughening device 20 includes a first smooth wheel support structure 80 supporting a first light wheel 201, a first roughened wheel support structure 81 supporting a first roughened wheel 202, a second smooth wheel support structure 82 supporting a second light wheel 203, and a second roughened wheel support structure 83 supporting a second roughened wheel 204. The first roughening wheel support structure 81 includes a support plate 801 and an intermediate connection member 802, the support plate 801 and the intermediate connection member 802 being connected by means of a connection member 803 (see fig. 6), the intermediate connection member 802 being connected to the first roughening wheel 202. The first smooth wheel supporting structure 80, the second smooth wheel supporting structure 82 and the second rough wheel supporting structure 83 have the same structure as the first rough wheel supporting structure 81, and will not be described again. In some exemplary embodiments, the connection 803 is a threaded connection.

Referring again to fig. 4, the first roughening wheel drive 32 is disposed on a side of the first roughening wheel support structure 81 facing away from the first roughening wheel 202, the first smooth wheel drive 31 is disposed on a side of the first smooth wheel support structure 80 facing away from the first optical pulley 201, the second smooth wheel drive 33 is disposed on a side of the second smooth wheel support structure 82 facing away from the second optical pulley 203, and the second rough wheel drive 34 is disposed on a side of the second rough wheel support structure 83 facing away from the second rough wheel 204.

In some exemplary embodiments, the first rough wheel driver 32, the first smooth wheel driver 31, the second smooth wheel driver 33, and the second rough wheel driver 34 are rodless cylinders.

In some exemplary embodiments, as shown in fig. 6, the support plate 801 is shaped as an L-shaped plate. The first portion of the L-shaped plate is connected to the intermediate connection 802 by means of connection 803. The second portions of the L-shaped plates are fixedly connected with the sliding portions of the respective driving members.

Fig. 5 is a perspective view of first optical block 201 and first roughening wheel 202 of the roughening device according to an exemplary embodiment of the present application. In one exemplary embodiment, as shown in fig. 5 (a), the first roughening wheel 202 includes a roughening 205 that roughens the film on the outer circumferential surface, as shown in fig. 5 (b), the first optical pulley 201 having a smooth outer circumferential surface. In one exemplary embodiment, the roughening 205 includes a plurality of grooves extending helically in the circumferential direction. In another exemplary embodiment, the roughening includes a plurality of teeth extending helically in a circumferential direction. The second optical wheel 203 and the second roughening wheel 204 have the same structure as the first optical wheel 201 and the first roughening wheel 202, and are not described here.

In some exemplary embodiments, the first roughening wheel 202 includes a roughening 205 that roughens the film on the outer circumferential surface, the roughening 205 including a plurality of protrusions or a plurality of recesses extending in the circumferential or axial direction on the outer circumferential surface. The second roughening wheel 204 has the same structure as the first roughening wheel 202, and will not be described again.

It should be appreciated that the roughening of the first roughening wheel 202 and the roughening of the second roughening wheel 204 may be provided differently. For example, the roughened portion of the first roughening wheel 202 and the roughened portion of the second roughening wheel 204 may be provided with different sizes and configurations.

Referring again to fig. 5, in some exemplary embodiments, the dimension L of the roughening 205 on the outer circumferential surface along the axial direction of the respective roughening wheel is in the range of 4 to 9 millimeters, optionally 4 to 6 millimeters.

Fig. 6 and 7 illustrate a roughening wheel angle adjustment 8011 of a corresponding roughening wheel according to an exemplary embodiment of the application. Referring to fig. 6 and 7, in some exemplary embodiments, the support plate 801 of the support structure 80 includes a roughening wheel angle adjustment 8011, and the first roughening wheel 202 is rotated by a rotation of the intermediate connection 802 (e.g., as shown by the arrow direction in fig. 6) relative to the roughening wheel angle adjustment 8011 through a certain angle along the component carrier 60.

In some exemplary embodiments, the respective roughening wheels may be configured with a different plurality of roughening. The plurality of roughened portions have different configurations and/or have different surface roughness from each other, so that different roughened portions can be selected according to the characteristics of the film of the component carrier, or flexibly selected according to different process requirements, thereby roughening the film to different degrees. Specifically, in the case where the thickness of the film of the component carrier is large or the rigidity is large, the roughening wheel can be rotated by a certain angle along the surface of the component carrier by rotating the intermediate connection member relative to the roughening wheel angle adjustment portion along the arrow in fig. 6, so that: the contact area of the roughened portion of the roughening wheel with the film increases, thereby increasing the size of the roughened portion of the film in the conveying direction a; or the coarsening part with larger roughness of the coarsening wheel is contacted with the film, so that the coarsening effect of the film is further improved, and the coarsening wheel is suitable for manufacturing requirements of component carriers with different types and different materials.

In alternative embodiments, each of the respective roughening wheel and optical pulley may be configured to have a smooth portion and a roughened portion. In this embodiment, each of the roughening wheel and the optical pulley has a respective angle adjustment. The respective wheel may be rotated along the component carrier by a rotation of the intermediate connection relative to the angle adjustment portion by an angle such that the smooth and/or roughened portion of the respective wheel is in contact with the film of the upper and/or lower surface of the component carrier. The design can flexibly adjust the coarsening part and the smooth part, and flexibly select the coarsening part or the smooth part according to actual production conditions, so that the production is ensured not to be interrupted under any conditions, and the production efficiency is ensured to the greatest extent. In other words, on the one hand, the "optical pulley" described in the present application may also be designed to include a roughened portion having a predetermined size extending in the axial direction thereof, so as to be a spare part. When the roughening wheel of the peeling device fails or fails, the purpose of roughening the film can be achieved by adjusting the smooth wheel with the roughening part. On the other hand, each of the "smooth wheel" and the "rough wheel" described in the present application is a "wheel" having a rough portion and a smooth portion of a certain size, and each of the "wheels" may be adjusted with its corresponding "wheel" in the vertical direction by the angle adjusting portion so that the smooth portion of the corresponding wheel is applied on the film, or the rough portion is applied on the film so that the corresponding "wheel" in the two vertical directions exhibits any combination of "rough-smooth", "rough-rough", "smooth-smooth" from top to bottom.

Fig. 8 is a schematic view of an operation state in which a film attached to an upper surface of a component carrier is roughened by a peeling apparatus according to an exemplary embodiment of the present application. Referring to fig. 8 and 10, the first roughening wheel 202 and the first optical pulley 201 are disposed on the upper and lower sides of the component carrier 60 in the vertical direction Y, respectively, such that the outer circumferential surfaces of the first roughening wheel 202 and the first optical pulley 201 face the upper and lower surfaces 61 and 62 of the component carrier 60, respectively. The second optical pulley 203 and the second roughening wheel 204 are respectively arranged on the upper side and the lower side of the component carrier 60 in the vertical direction Y such that the outer circumferential surfaces of the second optical pulley 203 and the second roughening wheel 204 face the upper surface 61 and the lower surface 62 of the component carrier 60, respectively. The first optical pulley 201 and the first roughening wheel 202 are disposed spaced apart from each other in the lateral direction X from the second optical pulley 203 and the second roughening wheel 204, as can be clearly seen from fig. 10. The first roughening wheel 202 and the second roughening wheel 204 are provided on the upper side and the lower side of the component carrier 60, respectively. As shown in fig. 8, after the component carrier 60 is conveyed to the first preset position I by the conveying device 10 in the conveying direction a, the conveying device 10 stops moving, and the component carrier 60 is fixed to the first table at the first preset position I. The first roughening wheel drive 32 and the first smooth wheel drive 31 apply driving forces to the first roughening wheel 202 and the first optical pulley 201, respectively, such that the first roughening wheel 202 and the first optical pulley 201 move in the vertical direction Y toward the upper surface 61 and the lower surface 62 of the component carrier 60 at the same time, thereby bringing the first roughening wheel 202 into contact with at least a portion of the film attached on the upper surface 61 of the component carrier 60 and bringing the first optical pulley 201 into contact with at least a portion of the film attached on the lower surface 62 of the component carrier 60, as shown in fig. 10. The second driving device 50 reciprocates the roughening device 20 in the lateral direction X with respect to the component carrier 60, thereby roughening at least a portion of the film attached to the upper surface 61 of the component carrier 60 to make the adhesive tape more easily attached to the film.

In the exemplary embodiment shown in fig. 8, roughening of the film on the upper surface can be accomplished by moving roughening device 20 in lateral direction X for 5 strokes over upper surface 60 of the component carrier. In some exemplary embodiments, one stroke refers to a distance that roughening device 20 moves from one side of the component carrier to the other side in lateral direction X. In some exemplary embodiments, the speed of the roughening device is 5-20m/min.

Fig. 9 is a schematic view of an operation state in which a film on an upper surface of a component carrier is peeled by a peeling apparatus according to an exemplary embodiment of the present application. As shown in fig. 9, after the film attached to the upper surface 61 of the component carrier 60 is roughened, the conveying device 10 continues conveying the component carrier 60 to the second preset position II in the conveying direction a, and then the conveying device 10 stops moving again, the component carrier 60 being fixed to the second table at the second preset position II. The edge lifting device 40 located at the second preset position II and above the upper surface 61 of the component carrier 60 moves towards the roughened portion of the film attached to the upper surface 61 of the component carrier 60 and bonds the adhesive tape to the roughened portion of the film, and then the edge lifting device 40 moves away from the component carrier 60 in the vertical direction Y so as to lift the roughened portion of the film a predetermined distance in the vertical direction Y, while at the same time the gripping device 100 located above the upper surface 61 of the component carrier 60 grips the roughened portion of the film, after which the conveying device 10 continues to convey the component carrier 60 in the conveying direction a while the gripping device 100 gripping the roughened portion of the film moves in a direction opposite to the conveying direction a so as to peel the film from the upper surface 61 of the component carrier 60.

During roughening of the film attached to the upper surface 61 of the component carrier 60 as shown in fig. 8 and 10, the second smooth wheel drive 33 and the second rough wheel drive 34 do not exert a driving force on the connected support structure, and therefore the second light wheel 203 and the second rough wheel 204 are positioned at a distance from the upper surface 61 and the lower surface 62 of the component carrier 60 as shown in fig. 10.

In case it is desired to peel off the film of the lower surface 62 of the component carrier 60, the first optical pulley 201 and the first rough wheel 202 are positioned at a distance from the lower surface 62 and the upper surface 61 of the component carrier. The second smooth wheel drive 33 and the second roughening wheel drive 34 apply driving forces to the second optical pulley 203 and the second roughening wheel 204, respectively, such that the second optical pulley 203 and the second roughening wheel 204 move simultaneously in the vertical direction Y toward the upper surface 61 and the lower surface 62 of the component carrier 60, thereby bringing the second roughening wheel 204 into contact with at least a portion of the film attached to the lower surface 62 of the component carrier 60 and bringing the second optical pulley 203 into contact with at least a portion of the film attached to the upper surface 61 of the component carrier 60, and the second driving device 50 reciprocates the roughening device 20 in the lateral direction X with respect to the component carrier 60, thereby roughening at least a portion of the film attached to the lower surface 62 to make the adhesive tape more easily attached to the film.

After roughening the film attached to the lower surface 62 of the component carrier 60, the conveying device 10 continues to convey the component carrier 60 in the conveying direction a to the second preset position II, the component carrier 60 is fixed to the second table at the second preset position II, and the conveying device 10 stops the movement again. The edge lifting device 40 located at the second preset position II and below the lower surface 62 of the component carrier 60 moves towards the roughened portion of the film attached to the lower surface 62 of the component carrier 60 and bonds the adhesive tape to the roughened portion of the film, and then the edge lifting device 40 moves away from the component carrier 60 in the vertical direction Y, thereby lifting the roughened portion of the film by a predetermined distance, while at the same time the gripping device 100 located below the lower surface 62 of the component carrier 60 grips the glued portion of the film, after which the conveying device 10 continues to convey the component carrier 60 in the conveying direction a, while the gripping device 100 gripping the glued portion of the film moves in a direction opposite to the conveying direction a, thereby peeling the film from the lower surface 62 of the component carrier 60.

In the case where it is necessary to roughen the films of the upper surface 61 and the lower surface 62 of the component carrier 60, after the component carrier 60 is conveyed to the first preset position I by the conveying device 10 in the conveying direction a, the conveying device 10 stops moving, the component carrier 60 is fixed to the first table at the first preset position I, the first roughening wheel driver 32 and the first smooth wheel driver 31 apply driving forces to the first roughening wheel 202 and the first optical pulley 201, respectively, and the second smooth wheel driver 33 and the second roughening wheel driver 34 apply driving forces to the second optical pulley 203 and the second roughening wheel 204, respectively, so that the first roughening wheel 202, the first optical pulley 201, the second optical pulley 203, and the second roughening wheel 204 move toward the upper surface 61 and the lower surface 62 of the component carrier 60 at the same time, thereby causing: the first roughening wheel 202 and the first optical pulley 201 are in contact with at least a portion of the film attached to the upper surface 61 and the lower surface 62 of the component carrier 60, and the second optical pulley 203 and the second roughening wheel 204 are in contact with at least a portion of the film attached to the upper surface 61 and the lower surface 62 of the component carrier 60. The second driving device 50 reciprocates the roughening device 20 in the lateral direction X with respect to the component carrier 60, thereby roughening at least a portion of the film attached to the upper surface 61 and the lower surface 62 to make the adhesive tape more easily attached to the film.

After the films attached to the upper surface 61 and the lower surface 62 are roughened, the conveying device 10 continues to convey the component carrier 60 to the second preset position II in the conveying direction a, and then the conveying device 10 stops moving again, the component carrier 60 being fixed to the second table at the second preset position II. The edge lifting means located above the upper surface 61 of the component carrier 60 and the edge lifting means located below the lower surface 62 move toward the roughened portion of the film attached to the upper surface 61 and the lower surface 62 of the component carrier 60, the adhesive tape is bonded to the roughened portion of the film attached to the upper surface 61 and the lower surface 62 of the component carrier 60, and then the edge lifting means moves away from the component carrier 60 in the vertical direction Y so as to lift the roughened portion of the film a predetermined distance in the vertical direction Y, while at the same time the gripping means located above the upper surface 61 of the component carrier 60 grips the lifted portion of the film attached to the upper surface 61 and the gripping means located below the lower surface 62 of the component carrier 60 grips the lifted portion of the film of the lower surface 62, after which the conveying means 10 continues the component carrier 60 in the conveying direction a while the two gripping means gripping the roughened portion of the film are moved in a direction opposite to the conveying direction a so as to peel the film of the upper surface 61 and the lower surface 62 from the upper surface 61 and the lower surface 62 of the component carrier 60.

In some exemplary embodiments, the peeling apparatus may further include a blowing device (not shown) disposed on one side of the conveying device 10 in the lateral direction downstream of the second preset position. After the film is peeled from the upper surface 61 and/or the lower surface 62 of the component carrier 60, the conveying device 10 causes the component carrier 60 to continue to be conveyed in the conveying direction a to the blowing device, which blows the peeled film into the recovery device located on the other side in the transverse direction of the conveying device. In an exemplary embodiment, the blowing device is a blower or a fan.

In some exemplary embodiments, the stripping apparatus may further include a detection device (not shown) located downstream of the blowing device. The detecting device determines whether the film is peeled from the component carrier. If it is determined that the film is successfully peeled from the component carrier, the component carrier is continued to be transported to the next process. If it is determined that the film is not peeled from the component carrier, the detection device will signal that peeling has failed.
