Description

  The present invention relates to a trimming device for a sheet member affixed to a substrate such as transparent glass. More specifically, the trimming device includes a surplus portion protruding from the periphery of the substrate and an adhering portion to a chamfered portion along the periphery. The present invention relates to a trimming device for a sheet member affixed to a substrate, which can be carried out at a low cost, can reduce the installation area of the entire device, and can reduce the working time.

  The photoelectric conversion module has a back sheet pasted on one side of the glass substrate via an adhesive layer. This back sheet is pasted so that it protrudes from the periphery of the glass substrate, and the excess part that protrudes is adhesive. It is excised with a cutting tool such as a cutter together with the layer. In the trimming apparatus for cutting off the surplus portion, conventionally, a support moving table provided so as to be movable in one direction along the upper surface of the work table, and another direction orthogonal to the one direction on the support moving table. Some include a trimming unit that is movable (see, for example, Patent Document 1).

  In the conventional trimming apparatus, the trimming unit includes a support body that can rotate around a rotation axis that is orthogonal to the upper surface of the workbench, and the surplus section is provided on the support body. A resecting tool to be resected is supported. Then, after the substrate is placed on the work table, the peripheral portion of the substrate is detected by a predetermined position detecting means, and based on the detection result, the movement of the support moving table and the trimming unit and the support are performed. By the rotation of the main part, the cutting tool is moved along the detected peripheral edge of the substrate, and the redundant part is cut by the cutting tool.

JP 2001-320069 A

  The substrate may be fitted with a frame at the periphery after the trimming process. For this reason, in order to easily fit the frame body, a chamfered portion made of an inclined surface or the like is often formed between the side surface and the peripheral surface of the one surface to which the back sheet is attached. In this case, when the surplus portion that protrudes from the peripheral edge of the substrate is cut out by the conventional trimming apparatus, the peripheral edge portion of the back sheet after the cutting is in a state of adhering to the chamfered portion. For this reason, when the frame is attached to the periphery of the substrate, the frame is caught on the periphery of the backsheet attached to the chamfered portion and is difficult to fit, and the periphery of the backsheet is rolled and defective. There is also a risk of becoming.

  In order to solve this problem, it is conceivable that the peripheral portion of the back sheet attached to the chamfered portion is also cut off by the trimming device. However, since the cutting tool of this trimming device is held in a predetermined posture along the side surface of the substrate, for example, a vertical posture, and is fixed to the support portion main body, the cutting tool attached to the inclined chamfered portion is provided. The periphery cannot be excised. Therefore, conventionally, a second trimming device different from the above trimming device is used, and the excision tool of the second trimming device is tilted to 45 degrees, for example, so as to fit the inclined surface of the chamfered portion. Then, after the surplus portion protruding from the side surface of the substrate is cut out by the trimming device, the substrate is transferred to the second trimming device, and then the peripheral portion attached to the chamfered portion is the second trimming device. Remove with a cutting tool.

However, when two trimming apparatuses are used in this way, the equipment cost is expensive, and it is necessary to secure a large installation area for the entire equipment, and the above-mentioned substrate is placed on the work table of the second trimming apparatus. In addition to transferring, the peripheral edge of the transferred substrate must be detected again, and it is not easy to shorten the working time.

  The technical problem of the present invention is to solve the above-mentioned problems and to cut off the surplus part protruding from the peripheral edge of the substrate and the adhering part to the chamfered part along the peripheral edge with a single trimming device. An object of the present invention is to provide a trimming device for a sheet member affixed to a substrate, which can be implemented and can reduce the installation area of the entire apparatus and reduce the working time.

In order to solve the above problems, the present invention will be described as follows, for example, based on FIGS. 1 to 7 showing an embodiment of the present invention.
That is, the present invention relates to a trimming device for a sheet member affixed to a substrate, and protrudes from the substrate (4) generated at the periphery of the sheet member (5) attached to one surface of the substrate (4) having a predetermined shape. A trimming device for cutting off the surplus portion (6), a support moving base (9) provided so as to be movable in one direction along the upper surface (2a) of the work table (2), and the supporting movement A trimming unit (10) is provided on the table (9) so as to be movable in another direction orthogonal to the one direction, and the trimming unit (10) is a rotation orthogonal to the work table upper surface (2a). A support body (15) that is rotatable around the axis of movement (18) is provided, and the support body (15) includes a resection tool (17) that cuts off the surplus part (6) and a swivel part. (16), and the excision tool (17) moves the support moving table (9) and the trimming unit (10) and the support body (15). The revolving part (16) can be moved along the periphery of the substrate (4) by movement, and the revolving part (16) is cut around a revolving center (25) along the moving direction of the resecting tool (17). It is characterized by being able to turn with the tool (17).

  When the substrate is placed at a predetermined position on the upper surface of the work table, the support moving table and the trimming unit are moved, the support body is rotated at the predetermined position, and the cutting tool is moved. It is moved along the periphery of the substrate. At this time, the cutting tool is in a vertical position, for example, in a posture along the side surface of the substrate, and the excess portion of the sheet member is cut by the cutting tool. Next, the turning part is turned about the turning center by an inclination angle of the chamfered part, for example, 45 degrees, so that the posture of the excision tool becomes an inclined posture along the chamfered part. Thereafter, the support moving base and the trimming unit are moved, the support body is rotated at a predetermined position, and the cutting tool is moved again along the peripheral edge of the substrate, whereby the sheet member is moved. Of the peripheral edge, the adhesion portion to the chamfered portion of the substrate is cut off.

  Here, for the peripheral edge of the substrate, for example, a detecting means is attached to a work table, a trimming unit, etc., and the peripheral position of the substrate is detected by this detecting means prior to the movement of the trimming unit, etc. It is preferable to control the movement of the support moving table and the trimming unit and the rotation of the support main body based on the detection result.

  The substrate is not limited to a specific material, shape, or application as long as a sheet member is attached to one side. For example, it may be a rectangular glass substrate or the like having a back sheet affixed on one side, which is used for a photoelectric conversion module, or may be a glass substrate or the like having a thin film such as a heat reflecting film affixed thereto. This substrate is not limited to transparent glass, and may be formed of metal or other material, or may be one obtained by attaching a photoelectric conversion element, an electrode, or the like to this substrate. Further, the shape of the substrate is not limited as long as a chamfered portion is formed along the periphery, and is usually formed in a rectangular shape, but the corners may be formed in a smooth curve such as an arc shape, May be in the shape of an ellipse, for example, whose periphery is a curve.

The sheet member is not limited to a specific material as long as it is a member capable of excising the surplus part and the like with the excision tool. For example, it may be of a single-layer structure consisting only of an adhesive sheet member, or for improving the weather resistance applied to the surface of the first sheet member having adhesiveness and the first sheet member. It may have a two-layer structure composed of the second sheet member. Specific examples of the material for these sheet members include transparent synthetic resins such as silicon, ethylene vinyl acetate (EVA), and polyvinyl butyral. Moreover, as said 2nd sealing part, there exists a thing of a single sheet | seat structure and a laminated structure, but as a 2nd sealing part of a single sheet | seat structure, fluorine-type resin, such as a brand name Tedlar, polyethylene terephthalate, etc. The second sealing portion of the laminated structure is a laminated sheet obtained by laminating a metal film such as aluminum or a thin film such as SiO _{2 on} one surface of the sheet made of the fluorine resin, polyethylene terephthalate, or the like. Alternatively, a laminated sheet obtained by laminating EVA on both surfaces of an aluminum alloy thin film, a laminated sheet obtained by laminating EVA on PET, or the like may be used.

  The above workbench is not limited to a specific shape, size, or structure as long as it can carry the substrate in and out and can hold the substrate in a predetermined position on the upper surface, such as a rectangle or square, Any shape can be used. However, it is preferable that this work table is provided with transfer means so that the above-mentioned substrate can be easily moved along the upper surface, and it is preferable that it is provided with fixing means such as suction means that can fix the substrate at a predetermined position. Examples of the transfer means include a configuration in which air is ejected from the upper surface of the work table so that the substrate can float, and a configuration in which a conveyor belt is disposed along the upper surface of the work table. It is not limited to.

  The revolving part is not limited to a specific structure as long as the resecting tool can be revolved around a predetermined revolving center. For example, an arcuate guide curved around the turning center and a rack member such as a timing belt arranged along the arcuate guide are provided on the support body, and the arcuate guide A guide portion to be guided, a turning gear that rotates while meshing with the rack member, and a turning drive means that turns the turning gear may be provided in the turning portion. In this case, when the turning gear is turned by the turning drive means, the guide portion is guided by the arcuate guide, and the turning portion turns around a predetermined turning center. Thereby, said cutting tool can accompany this turning part, and can turn reliably around the predetermined turning center, and is preferable. For example, a slide rail or the like is preferably used as the arc-shaped guide, and a slide unit or the like is preferably used as the guide portion. However, the arc-shaped guide and the guide portion used in the present invention are not limited to these. .

  Further, between the support unit main body and the swivel unit, when provided with posture holding means for supporting the swivel unit so as to be movable in the swivel direction and holding the posture of the swivel unit, the swivel unit swivels. Even so, it is possible to stably hold the posture, and it is preferable that the posture of the cutting tool supported by the support portion main body via the turning portion can be securely held without wobbling. In addition, this attitude | position holding means may be provided in the support part main body side, may support a turning part, and may be provided in a turning part side and may support a support part main body.

  The excision tool is not limited to a specific one as long as it can excise the surplus portion of the sheet member. For example, a metal cutter made of SK material, preferably high-speed steel that can be expected to have a long life, an ultrasonic cutter, a hot cutter, or the like can be used. When a metal cutter is used, it is preferable because it does not use an amplifier or the like and can be implemented at a low cost, and heat generated by cutting can be suppressed. Moreover, when using said hot cutter, the temperature of the cutter board is arbitrarily set, for example within the range of 100-700 degreeC by the material etc. of a sealing member. In this case, in order to prevent the excess portion of the sheet member from reattaching to the side surface of the substrate immediately after excision, or to prevent thermal influence on the sheet member etc., the contact time between the sheet member and the excision tool From this point of view, it is desirable that the moving speed of the cutting tool is 100 mm / second or more.

  When the cutting tool has a linear cutting edge, such as when the cutting tool is a metal cutter, the cutting edge is arranged so as to intersect the rotation axis, and the turning center is the blade edge and the rotation axis. By setting the position passing through the intersection with the center, the cutting point is formed at the position where the rotation center, the turning center and the cutting edge intersect, that is, the position where the sheet member is cut at the cutting edge, thereby The above cutting point can always be maintained at a predetermined position with respect to the trimming unit regardless of the turning posture of the cutting tool and the rotation of the support body. As a result, it is preferable that the excision tool can be reliably moved along the periphery of the substrate by the movement of the support platform and the trimming unit and the rotation of the support body. Note that there may be an error about the bending allowance of the resecting tool in the arrangement position of the cutting edge and the setting position of the turning center.

  In addition, the swivel unit may be provided with only one excision tool, but each of the excision tools is provided with an excision tool on the opposite side of the traveling direction with the pivot axis interposed therebetween. When the cutting position with each blade tip protruding and the retracted posture with the blade tip retracted can be switched, when cutting off the surplus part etc. along the peripheral edge of the substrate, one cutting tool can be used to remove the middle part of the peripheral edge. After cutting from one end to the other, switch one of the cutting tools to the retracted position, switch the other cutting tool to the cutting position, and reverse the moving direction of the trimming unit. It can be made to cut from the part to the other end. In other words, there is no need to change the orientation of the excision tool by rotating the support body around the pivot axis by 180 degrees, especially when the excision tool excises the adhering portion to the chamfered portion. Since it is not necessary to incline to the side, it is preferable that an excess portion on the peripheral edge of the substrate and an adhesion portion to the chamfered portion can be easily cut.

  The cutting tool may be arranged along the side surface of the substrate. For example, the cutting tool may be arranged with a tilt angle of 30 degrees or less with respect to the side surface. There is an advantage that it can be used as a scraper that separates the substrate from the substrate.

  Since the trimming device for the sheet member affixed to the substrate of the present invention is configured and operates as described above, the following effects are obtained.

  (1) The above excision tool can be switched between the posture along the side surface of the substrate and the inclined posture along the chamfered portion by turning around the turning center, and thereby the excess portion protruding from the peripheral edge of the substrate. And a chamfered portion along the periphery thereof can be excised with a single trimming device, which can be carried out at a low cost and the installation area of the entire device can be reduced.

  (2) Since the surplus portion that protrudes from the peripheral edge of the substrate and the adhering portion to the chamfered portion along the peripheral edge can be removed by one trimming device, unlike the above-described conventional technique, between the two trimming devices. It is not necessary to transfer the substrate, and it is not necessary to detect the periphery of the substrate after the transfer again, so that the entire trimming operation time can be shortened.

It is sectional drawing of the principal part of the board | substrate at the time of excising the adhesion part to an. It is the perspective view which expanded the front-end | tip part of the cutting tool which is excising the excess part of embodiment of this invention.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, the trimming device (1) includes a work table (2) formed in a substantially rectangular shape in plan view, and guide rails (2) extend along the longitudinal direction of the work table (2). 3) is provided. On the work table (2), a substrate (4) such as a photoelectric conversion module is placed at a predetermined position on the upper surface (2a). The substrate (4) is made of, for example, transparent glass, and a chamfered portion (4b) is formed between the side surface (4a) along the periphery, and a sheet member (5) is stuck on the surface. A surplus portion (6) protruding beyond the side surface (4a) is formed on the peripheral edge of the sheet member (5).

  A large number of air jets (7) are opened on the upper surface (2a) of the work table (2), and the substrate (4) is formed by the air jetted from the air jets (7). It is surfaced and can be moved easily. Further, the upper surface (2a) is provided with vacuum suction portions (8) at predetermined intervals, and the substrate (4) is held immovable to a predetermined position by suction by the vacuum suction portion (8). ing. The vacuum suction section (8) releases suction when the substrate (4) is moved, and retreats downward from the upper surface (2a) so as not to hinder the movement of the substrate (4). .

  Above the work table (2), there is provided a support moving table (9) movable along the upper surface (2a). The support moving table (9) is provided with the guide rail (3). Thus, it can be moved in one direction (X direction). The support moving table (9) is provided with a trimming unit (10), and the trimming unit (10) moves in the other direction (Y direction) orthogonal to the X direction. ) Is configured to be movable along.

  As shown in FIG. 2, the trimming unit (10) includes a cover (11) whose bottom surface is opened, a motor (12) disposed above the cover (11), and a gear portion on the motor (12). A pivot shaft (14) interlocked and coupled through the upper wall of the cover (11) through (13), a support body (15) fixed to the lower end of the pivot shaft (14), A swivel portion (16) supported by the support portion main body (15). The swivel part (16) is provided with a pair of excision tools (17) for excising the surplus part (6). Therefore, these excision tools (17) are interposed via the swivel part (16). Are supported by the support body (15). The rotation axis (18) of the rotation shaft (14) is orthogonal to the work table upper surface (2a), and the rotation of the rotation shaft (14) causes the support body ( 15) rotates around the rotation axis (18).

  As shown in FIGS. 3 and 4, the support body (15) includes a support plate (19) fixed to the rotating shaft (14), and an arcuate guide support ( And 20). The guide support portion (20) is provided with an arcuate guide (21) and a timing belt (22) as a rack member. The timing belt (22) is connected to the arcuate guide (21). It is supported by the receiving member (23) arranged along the both ends, and both ends are fixed to the tensioning tool (24). The arcuate guide (21) is, for example, a slide rail and is curved around a turning center (25) along the moving direction of the cutting tool (17). It is orthogonal to the rotation axis (18).

  On the other hand, the turning part (16) is a turning part that rotates and moves while meshing with the guide part (26) such as a slide guide guided by the arcuate guide (21) and the timing belt (22). Gear (27), a pair of tension pulleys (28) disposed on both sides of the turning gear (27), and a turning drive means (29) for rotating the turning gear (27). is there. The timing belt (22) is passed between the turning gear (27) and the tension pulley (28). For this reason, when the turning gear (27) is rotated by the turning drive means (29), the turning gear (27) moves in the extending direction of the timing belt (22) and is fixed to the turning portion (16). The guide part (26) is guided by the arcuate guide (21). As a result, the entire revolving unit (16) is revolved around the revolving center (25) by a predetermined angle such as 30 degrees, 45 degrees, or 60 degrees, and the resecting tool (17) is turned into FIG. It is switched between the vertical posture (V) shown in (a) and the inclined posture (W) inclined by a predetermined angle (α) shown in FIG. 6 (b).

  Further, as shown in FIG. 4, posture holding means (30) composed of a pair of rolls is provided at the lower end of the turning portion (16), and the guide support portion (20) is provided by the posture holding means (30). ) Is clamped at the bottom. Note that a proximity sensor (31) is fixed to the guide support portion (20), and the turning portion (16) is predetermined by detecting the pointing member (32) attached to the posture holding means (30). It is detected that the vehicle has turned to the position.

  Each of the cutting tools (17) is made of a metal cutter and, as shown in FIGS. 2 and 5, is disposed on opposite sides of the traveling direction with the rotating shaft (18) in between. In addition, each cutting tool (17) is driven by a cylinder part (34) provided in the holding part (33) so that each cutting edge (35) protrudes to the opposite side from the rotation axis (18). It is possible to switch between the posture (C) and the retracted posture (B) retracted to the near side with respect to the rotation axis (18).

  In the cutting tool (17), the cutting edge (35) is linear, and in the cutting position (C), the cutting edge (35) intersects the rotational axis (18). It has become. Further, the turning center (25) of the turning part (16) is set at a position passing through the intersection of the cutting edge (35) and the rotation axis (18). This intersecting position is set as a cutting point (P) for cutting off the surplus portion (6) from the sheet member (5) with the cutting edge (35). Since this cutting point (P) is on the rotation axis (18), the support moving base (9) and the trimming unit (10) move, and the support body (15) rotates. However, the same relative position with respect to the trimming unit (10) is maintained. Therefore, by moving the trimming unit (10) along the periphery of the substrate (4), the cutting point (P) formed on the cutting edge (35) of the cutting tool (17) is also applied to the substrate. It moves along the periphery of (4).

Next, a procedure for cutting off the excess portion of the sheet member attached to the substrate by the trimming apparatus will be described.
When the substrate (4) is placed on the upper surface (2a) of the work table (2), the periphery of the substrate (4) is first detected by a detection means (not shown), and then along the detected periphery. A control device (not shown) controls the support moving base (9), the trimming unit (10), and the support portion main body (15), and the cutting tool (17) is moved along the periphery of the substrate (4). Make a round. The detection means may be fixed to the work table (2), for example, in the vicinity of the four corners of the substrate (4). In this case, the mounting position of the substrate (4) can be quickly determined. It is preferable because it can be detected. However, this detection means is attached to, for example, the trimming unit (10) or the vicinity thereof, and makes a round along the outline of the substrate (4) together with the trimming unit (10). You may detect a periphery. In this case, the detection means is moved along the peripheral edge of the substrate, which is preferable because it can be detected accurately.

  For example, when the trimming unit (10) is moved clockwise in FIG. 1, the trimming unit (10) is moved in the X direction along one long side of the substrate (4) by the movement of the support moving base (9). The excess part (6) which protrudes from the long side of this board | substrate (4) is moved, and it cuts out with said cutting tool (17). At this time, one cutting tool (17) on the lower side in the movement direction than the pivot axis (18) is switched to the cutting posture (C), and the other cutting tool (17) on the upper side in the movement direction is switched. Switched to the reverse posture (B). The cutting tool (17) in this cutting posture (C) is held in a vertical posture (V) along the side surface of the substrate (4) as shown in FIG. 6 (a). This cutting tool (17) is pressed against the side surface (4a) of the substrate (4) to be surely cut off the surplus part (6), and may be slightly bent. For this reason, the excision by the excision tool (17) is started from an intermediate portion of each side of the substrate (4) so that it does not collide with the substrate (4) at the excision start position. Excised.

  In this embodiment, for example, as shown in FIG. 6A, the substrate (4) is provided with a photoelectric conversion element (36) between the sheet member (5) and the sheet. The member (5) has a two-layer structure comprising a first sheet member (5a) having adhesiveness and a second sheet member (5b) attached to the first sheet member (5a). However, the present invention is not limited to this embodiment, and a sheet member may be directly affixed to one side of the substrate, and the sheet member is composed of only one layer or three or more layers. There may be.

  When the movement along the long side is completed, the support body (15) is rotated 90 degrees around the rotation axis (18), and the cutting edge (35) of the cutting tool (17) is placed on the substrate. Direct in the direction along the short side of (4). Next, the trimming unit (10) is moved in the Y direction along the support moving base (9), and as in the case of the long side, the surplus portion (6) extends from the intermediate portion to the lower end portion. Excise. When the movement along the short side is completed, the trimming unit (10) is turned after rotating the support body (15) in the same manner for the remaining other long sides and short sides in the same procedure as above. Move and cut off the surplus part (6) of the lower side of each remaining side with the cutting tool (17).

  As a result of the above operation, the surplus portion (6) of the lower side of the clockwise side of each side of the substrate (4) is all removed, and the trimming unit (10) returns to the first corner portion. At this position, the one excision tool (17) is switched to the retracted position (B), and the other excision tool (17) is switched to the excision position (C). The moving direction is counterclockwise opposite to the above, but the supporting moving base (9), the trimming unit (10) and the supporting body (15) are controlled in the same manner as the above procedure. The excision tool (17) is moved along the periphery of the substrate (4), and the surplus portions (6) remaining on each side are excised with the excision tool (17). When the excision of the surplus portion (6) is completed, the trimming unit (10) returns to the first corner portion again.

  Next, the one excision tool (17) is switched to the excision posture (C), the other excision tool (17) is switched to the receding posture (B), and the turning part (16) is turned to the turning center ( 25) Turn around a predetermined angle (α), for example 45 degrees. Accordingly, the cutting tool (17) has an inclined posture (W) along the chamfered portion (4b) of the substrate (4), for example, as shown in FIG. 6 (b). Then, similarly to the case of cutting off the surplus part (6), the support moving base (9), the trimming unit (10) and the support part main body (15) are controlled, and the cutting tool is cut. (17) is rotated clockwise along the periphery of the substrate (4), then one excision tool (17) is switched to the retracted position (B), and the other excision tool (17) is excised (C). And turn around counterclockwise.

  By the above operation, the attachment portion (37) attached to the chamfered portion (4b) of each side of the substrate (4) in the sheet member (5) is cut out by the cutting tool (17). At this time, as shown in FIG. 7, the rotational axis (18), the cutting edge (35) of the cutting tool (17), and the turning center (25) are aligned at the cutting point (P). The cutting point (P) does not move when the support body (15) is turned or when the turning portion (16) is turned by a predetermined angle (α). For this reason, the cutting edge (35) of the cutting tool (17) is always positioned on the cutting point (P), and the cutting point (P) can be transferred to the substrate (by simply moving the trimming unit (10)). 4) It can move along the peripheral edge, and the surplus part (6) and the adhering part (37) to the chamfered part (4b) are reliably excised by the excision tool (17). The pivot center (25) is preferably substantially aligned with the ridge line between the side surface (4a) and the chamfered portion (4b) of the substrate (4) as shown in FIG.

  The trimming apparatus described in the above embodiment is exemplified to embody the technical idea of the present invention, and the shape, dimensions, structure, material, etc. of each part are not limited to those of this embodiment. Rather, various modifications can be made within the scope of the claims of the present invention.

  For example, in the above-described embodiment, a substantially rectangular work table is used. However, this work table may be a square or other shapes, or may be provided with a belt conveyor or the like. In the above-described embodiment, the support moving base is moved along the guide rail. However, the guide rail may be formed on any part of the work table, or may be moved by other means. The table may be moved.

  In the above embodiment, as the configuration for turning the turning portion, the timing belt, the turning gear meshing with the timing belt, and the arcuate slide rail and the slide guide are used. There is an advantage that you can turn. However, in the present invention, it is only necessary to be able to turn the turning portion around the turning center, and the invention is not limited to the above configuration, for example, an arc-shaped rack gear is used instead of the timing belt.

Further, in the above embodiment, a pair of cutting tools made of a metal cutter is used, but in the present invention, only one cutting tool may be used. The excision tool may be other than a metal cutter such as an ultrasonic cutter.
The substrate is not limited to a rectangle, and may be another substrate other than the photoelectric conversion module, such as a plate glass attached with a heat ray reflective film, and the sheet member may be a single layer. Needless to say, these materials are not limited to specific ones.

  The trimming device for a sheet member affixed to a substrate of the present invention is inexpensive by cutting off the surplus portion protruding from the peripheral edge of the substrate and the adhering portion to the chamfered portion along the peripheral edge with a single trimming device. In addition, the installation area of the entire apparatus can be reduced, and the work time can be shortened. Therefore, it is particularly suitable as a trimming apparatus for a sheet member attached to a substrate such as a photoelectric conversion module. It is also suitable as a trimming device for a sheet member attached to a substrate.
