[0002] When marking photovoltaic modules, laser marking equipment is usually used. However, in the related art, only a single light source is used to mark photovoltaic modules. When a single light source is used to mark photovoltaic modules, when the multi-layer thin films on the photovoltaic modules are vaporized and then erupted, the bottom film vaporizes first, and then it is easy to flip up the upper film, thereby forming an uneven morphology. Utility Model Content

[0003] The main purpose of the utility model is to provide a laser processing device and a photovoltaic module production line, aiming to improve the situation in the related art that when the laser processing equipment scribes the photovoltaic module, the film of the photovoltaic module is prone to form an uneven morphology.

[0004] To achieve the above-mentioned purpose, the laser processing equipment proposed in the utility model is used to mark a photovoltaic module along a first direction. The laser processing equipment includes a frame, a first light source and a second light source. The first light source is arranged on the frame. The second light source is arranged on the frame, and the light spot of the second light source is smaller than the light spot of the first light source; when the first light source and the second light source are both marking the photovoltaic module, the projection of the first light source on the photovoltaic module and the projection of the second light source on the photovoltaic module are arranged side by side in sequence along the first direction, and the marking area of ​​the first light source covers the marking area of ​​the second light source.

[0005] The technical solution of the utility model ensures the stability of the first light source and the second light source by arranging the first light source and the second light source on the frame. By setting the light spot of the second light source to be smaller than the light spot of the first light source, the first light source and the second light source are arranged side by side in sequence along the first direction, so that when the second light source marks the photovoltaic module before the first light source, the channel formed after the second light source irradiates the photovoltaic module is a channel for the substances generated when the film layer is vaporized when the first light source irradiates the photovoltaic module to be released from the narrower channel, that is, a release channel is provided in advance for the substances generated when the first light source irradiates the photovoltaic module to cause the film layer to be vaporized; and the channel formed when the first light source irradiates the photovoltaic module is wider than the channel formed when the second light source irradiates the photovoltaic module.

[0006] By covering the marked area of ​​the first light source with the marked area of ​​the second light source, the narrower channel formed by the second light source irradiating the photovoltaic module can be supplemented and covered by the wider channel formed by the first light source irradiating the photovoltaic module, thereby eliminating the phenomenon of the film layer on at least part of the photovoltaic module flipping up, so as to improve the uneven morphology formed when the laser processing equipment irradiates the photovoltaic module, and then reduce the influence of stress here, thereby reducing the risk of fracture here and the influence on the crystallization process of the film layer on the photovoltaic module, thereby increasing the service life of the photovoltaic module.

[0007] In one embodiment, the photovoltaic component includes a glass substrate and a film layer disposed on one side of the glass substrate, one of the first light source and the second light source is disposed toward the film layer, and the other is disposed toward a side of the glass substrate away from the film layer.

[0008] Such an arrangement can reduce the interference of dirt on the side of the glass substrate away from the film layer to the laser on the one hand, and reduce the interference of plasma to the laser on the other hand, so that the cooperation of the first light source and the second light source can effectively scribe the photovoltaic module.

[0009] In one embodiment, the first light source is disposed toward the film layer, and the second light source is disposed toward a side of the glass substrate away from the film layer.

[0011] In one embodiment, the first light source and the second light source are both slidably disposed on the frame and can move relative to the frame along the first direction.

[0012] Such an arrangement can ensure, on the one hand, the effect of the first light source and the second light source sliding along the first direction to mark the photovoltaic component along the first direction, and on the other hand, can reduce the risk of damaging the photovoltaic component due to frequent movement.

[0013] In one embodiment, the rack includes a first slider extending along a first direction, the first light source and the second light source are both provided with a first slide rail, and the first slider is slidably connected to the first slide rail; or, the rack includes a first slide rail extending along a first direction, the first light source and the second light source are both provided with a first slider, and the first slider is slidably connected to the first slide rail.

[0014] Such an arrangement can reduce the risk of wear of the first light source and the second light source when they slide relative to the frame, and can also provide a good guiding effect for the first light source and the second light source to slide in the first direction.

[0015] In one embodiment, the laser processing equipment further comprises a support frame assembly, wherein the support frame assembly has a support surface for supporting the photovoltaic assembly.

[0016] With such an arrangement, the photovoltaic assembly can be stably supported, thereby improving the stability of the photovoltaic assembly, which in turn facilitates the first light source and the second light source to perform more precise marking operations on the photovoltaic assembly.

[0017] In one embodiment, the support frame assembly includes a support seat body and a transmission mechanism. The transmission mechanism is disposed on the support seat body and has the support surface. The transmission mechanism extends along a second direction, and the second direction is disposed at an angle to the first direction.

[0018] With such configuration, the positions of the first light source and the second light source on the photovoltaic assembly can be changed by changing the position of the photovoltaic assembly in the second direction.

[0019] In one embodiment, at least two of the conveying mechanisms are provided along the first direction; and an auxiliary support assembly is also provided between at least two of the conveying mechanisms.

[0020] By providing at least two transmission mechanisms along the first direction, the support strength of the photovoltaic assembly can be improved on the one hand, and the transmission power consumption of each transmission mechanism can be reduced on the other hand. By providing an auxiliary support assembly between at least two transmission mechanisms, the support strength of the photovoltaic assembly can be further improved.

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0041] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0042] At present, laser scribing equipment is usually used for scribing photovoltaic modules. Photovoltaic modules include a glass substrate and a film layer provided on one side of the glass substrate. The side of the glass substrate facing away from the film layer is defined as the back side of the photovoltaic module, and the side where the film layer is located is defined as the front side of the photovoltaic module. In the related art, photovoltaic modules are only scribed by a single light source, and there are many defects when a single light source is used to scribing photovoltaic modules. For example, when a single light source is set on the back side of a photovoltaic module, the back side of the photovoltaic module usually has a lot of dirty substances, so it is easy to block the light source, so that a short circuit point of the light source is easy to appear, and then it makes it difficult for the laser to irradiate the film layer on the front side. When a single light source is set on the front side of the photovoltaic module, plasma generated by etching is likely to exist in the optical path of the light source, and these plasmas will block the light source from irradiating the film layer. In addition, when a single light source is used, no matter it is set on the back side or the front side of the photovoltaic module, since the film layer of the photovoltaic module includes multiple layers of thin films, the layer close to the glass substrate in the multi-layer thin film is usually a thin film that vaporizes faster. Therefore, the thin film close to the glass substrate vaporizes first and releases some plasma in an eruption manner, which causes the thin film far away from the glass substrate to be flipped up, thereby easily forming an uneven morphology.

[0043] In order to improve the situation that when laser processing equipment in the related art scribes photovoltaic modules, the film of the photovoltaic module is prone to form uneven topography, the utility model proposes a laser processing equipment.

[0044] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the laser processing device 1 is used to mark the photovoltaic module 2 along the first direction. The laser processing device 1 includes a frame 100, a first light source 210 and a second light source 220. The first light source 210 is arranged on the frame 100. The second light source 220 is arranged on the frame 100, and the light spot of the second light source 220 is smaller than the light spot of the first light source 210; when the first light source 210 and the second light source 220 are both marking the photovoltaic module 2, the projection of the first light source 210 on the photovoltaic module 2 and the projection of the second light source 220 on the photovoltaic module 2 are arranged side by side in sequence along the first direction, and the marking area of ​​the first light source 210 covers the marking area of ​​the second light source 220.

[0045] The rack 100 refers to a frame 120 assembly for mounting the first light source 210 and the second light source 220. The rack 100 may include a column and a beam connected to the column, and the first light source 210 and the second light source 220 are mounted on the beam. Alternatively, the rack 100 may include a base and an extension arm connected to the base, and the extension arm is provided with the first light source 210 and the second light source 220. Alternatively, the rack 100 includes a first beam, a second beam, and a support member connecting the first beam and the second beam, the first light source 210 is mounted on the first beam, the second light source 220 is mounted on the second beam, and the like. As long as the effect of providing the first light source 210 and the second light source 220 for installation can be achieved.

[0046] The first light source 210 is used to emit laser light, so as to scribe and etch the film layer on the glass substrate of the photovoltaic module 2. When the first light source 210 is disposed on the frame 100, it can be connected to the frame 100 by threaded connection, snap connection, welding or bonding.

[0047] The second light source 220 is used to emit laser light to scribe and etch the film layer on the glass substrate of the photovoltaic module 2. When the second light source 220 is disposed on the frame 100, it can also be connected to the frame 100 by threaded connection, snap connection, welding or bonding.

[0048] The light spot in this application refers to the light spot formed by the laser beam irradiating on the irradiation surface of the photovoltaic module 2, and the light spot is circular or elliptical, etc. Specifically, the light spot of the first light source 210 refers to the light spot formed by the laser beam emitted by the first light source 210 irradiating on the irradiation surface of the photovoltaic module 2. The light spot of the second light source 220 refers to the light spot formed by the laser beam emitted by the second light source 220 irradiating on the irradiation surface of the photovoltaic module 2.

[0049] The size of the light spot refers to the diameter of the light spot formed by the laser beam irradiating on the irradiated surface of the photovoltaic module 2. The difference between the second light source 220 and the first light source 210 in the technical solution of the utility model is that the light spot of the second light source 220 is smaller than the light spot of the first light source 210. That is, the diameter of the light spot irradiated on the photovoltaic module 2 by the second light source 220 is smaller than the diameter of the light spot irradiated on the photovoltaic module 2 by the first light source. In this way, the width of the line drawn by the second light source 220 on the photovoltaic module 2 will be smaller than the width of the line drawn by the first light source 210 on the photovoltaic module 2.

[0050] The first light source 210 and the second light source 220 in the laser processing device 1 are used to mark the photovoltaic module 2 along the first direction. Specifically, the first light source 210 and the second light source 220 in the laser processing device 1 move along the first direction, while the photovoltaic module 2 does not move; or, the first light source 210 and the second light source 220 in the laser processing device 1 do not move, while the photovoltaic module 2 moves in a direction opposite to the first direction. Specifically, when the photovoltaic module 2 does not move, and the first light source 210 and the second light source 220 move along the first direction, the second light source 220 is arranged at the front end of the first light source 210, and the second light source 220 always marks the photovoltaic module 2 along the first direction before the first light source 210. When the photovoltaic component 2 moves in a direction opposite to the first direction, and the first light source 210 and the second light source 220 are stationary, the second light source 220 can be arranged on one side of the first light source 210 along the first direction. At this time, in order to draw a line on the photovoltaic component 2 along the first direction, the photovoltaic component 2 will move relative to the first light source 210 and the second light source 220 in a direction away from the first direction. The photovoltaic component 2 is first irradiated by the second light source 220, so that the second light source 220 irradiates the photovoltaic component 2 to form a narrower channel, and then the first light source 210 is irradiated, so that the first light source 210 irradiates the photovoltaic component 2 to form a wider channel. When the first light source 210 and the second light source 220 are both marking the photovoltaic component 2, the projection of the first light source 210 on the photovoltaic component 2 and the projection of the second light source 220 on the photovoltaic component 2 are arranged side by side in sequence along the first direction. Therefore, no matter whether the first light source 210 and the second light source 220 move, or the photovoltaic component 2 moves, the second light source 220 will mark the photovoltaic component 2 before the first light source 210, and then in the marking direction of the photovoltaic component 2, the second light source 220 will first irradiate the photovoltaic component 2 to form a narrower channel on the photovoltaic component 2, and then the first light source 210 will irradiate the photovoltaic component 2 and form a wider channel on the photovoltaic component 2, so that the wider channel can cover the narrower channel, and can cover and at least partially eliminate the uneven morphology formed when the second light source 220 irradiates the photovoltaic component 2, thereby improving the problem that the laser processing equipment 1 is prone to form an uneven morphology when marking the photovoltaic component 2. It should be noted that the direction perpendicular to the photovoltaic module 2 is defined as the height direction, that is, the direction perpendicular to the plate surface of the glass substrate of the photovoltaic module 2 is the height direction; when the first light source 210 and the second light source 220 are arranged side by side in sequence along the first direction, the first light source 210 and the second light source 220 can be located at the same height or at different heights, as long as the projection of the first light source 210 on the photovoltaic module 2 and the projection of the second light source 220 on the photovoltaic module 2 are arranged side by side in sequence along the first direction. For example, the first light source 210 and the second light source 220 are both located on the same side of the photovoltaic module 2, or the first light source 210 and the second light source 220 are respectively located on opposite sides of the photovoltaic module 2.In addition, the axis of the first light source 210 is parallel to the axis of the second light source 220, and the plane formed by the axis of the first light source 210 and the axis of the second light source 220 can be set parallel to or approximately parallel to the first direction, as long as the marked area of ​​the first light source 210 on the photovoltaic component 2 can cover the marked area of ​​the second light source 220.

[0051] The technical solution of the utility model ensures the stability of the first light source 210 and the second light source 220 by arranging the first light source 210 and the second light source 220 on the frame 100. By setting the light spot of the second light source 220 to be smaller than the light spot of the first light source 210, the first light source 210 and the second light source 220 are arranged side by side in sequence along the first direction, so that when the second light source 220 marks the photovoltaic module 2 before the first light source 210, the channel formed after the second light source 220 irradiates the photovoltaic module 2 is the material generated when the film layer is vaporized when the first light source 210 irradiates the photovoltaic module 2, so that the material can be released from the narrow channel, that is, a release channel is provided in advance for the material generated when the first light source 210 irradiates the photovoltaic module 2 and causes the film layer to be vaporized; and the channel formed when the first light source 210 irradiates the photovoltaic module 2 is wider than the channel formed when the second light source 220 irradiates the photovoltaic module 2. By covering the marked area of ​​the first light source 210 with the marked area of ​​the second light source 220, the narrower channel formed by the second light source 220 irradiating the photovoltaic component 2 can be supplemented and covered by the wider channel formed by the first light source 210 irradiating the photovoltaic component 2, thereby eliminating the phenomenon of the film layer on at least part of the photovoltaic component 2 flipping up, so as to improve the uneven morphology formed when the laser processing equipment 1 irradiates the photovoltaic component 2, and then reduce the influence of stress here, thereby reducing the risk of fracture here and the influence on the crystallization process of the film layer in the photovoltaic component 2, thereby improving the service life of the photovoltaic component 2.

[0052] Please refer to Figure 1 and Figure 2 In one embodiment of the utility model, the photovoltaic component 2 includes a glass substrate and a film layer disposed on one side of the glass substrate, one of the first light source 210 and the second light source 220 is disposed toward the film layer, and the other one is disposed toward the side of the glass substrate away from the film layer.

[0053] Generally, the photovoltaic module 2 has two surfaces arranged opposite to each other, the front side of the photovoltaic module 2 may be a surface provided with a film layer, and the back side of the photovoltaic module 2 is a glass substrate. The back side of the photovoltaic module 2 usually contacts the conveying platform of the production line, so the back side of the photovoltaic module 2 is usually stained with dirt, which easily forms an obstacle to the laser light source. In the present application, by arranging one of the first light source 210 and the second light source 220 toward the film layer, the interference of dirt on the marking of the photovoltaic module 2 can be reduced.

[0054] In addition, it is understandable that plasma will be generated when the film layer is vaporized. By directing the other of the first light source 210 and the second light source 220 toward the side of the glass substrate away from the film layer, the risk of interference from plasma when scribing the photovoltaic component 2 can be reduced.

[0055] By arranging one of the first light source 210 and the second light source 220 toward the film layer and the other toward the side of the glass substrate away from the film layer, on the one hand, the interference of dirt on the side of the glass substrate away from the film layer to the laser can be reduced, and on the other hand, the interference of plasma to the laser can be reduced, so that the cooperation of the first light source 210 and the second light source 220 can effectively scribe the photovoltaic module 2.

[0056] Please refer to Figure 1 and Figure 2 In one embodiment of the present invention, the first light source 210 is disposed toward the film layer, and the second light source 220 is disposed toward a side of the glass substrate away from the film layer.

[0057] By setting the first light source 210 toward the film layer and the second light source 220 toward the side of the glass substrate away from the film layer, the second light source 220 first scribes the photovoltaic component 2 to produce a narrower channel, and then when the first light source 210 scribes the photovoltaic component 2 again, it can not only cover the narrower channel formed by the second light source 220 irradiating the photovoltaic component 2 to improve the uneven morphology, but also supplement the scribe at the place where the light irradiated by the second light source 220 is blocked by dirt, thereby reducing the influence of the short-circuit points formed by the dirt blocking the laser on the laser etching, thereby achieving a more effective scribing effect.

[0058] like Figure 1 As shown, in one embodiment of the present invention, the first light source 210 and the second light source 220 are both slidably disposed on the frame 100 and can move relative to the frame 100 along a first direction.

[0059] When the first light source 210 and the second light source 220 are slidably disposed on the frame 100, a driving device may be provided to drive the first light source 210 and the second light source 220 to move in the first direction. For example, the driving assembly may be a linear motor, a cylinder, or driven by a lead screw nut assembly. Of course, without considering automation, the first light source 210 and the second light source 220 may also be manually operated to move relative to the frame 100 in the first direction.

[0060] By sliding the first light source 210 and the second light source 220 on the frame 100, on the one hand, the first light source 210 and the second light source 220 can slide in the first direction to draw lines on the photovoltaic component 2 along the first direction. On the other hand, the risk of damaging the photovoltaic component 2 by frequent movement can be reduced.

[0061] like Figure 1 As shown, in one embodiment of the utility model, the frame 100 includes a first slider 201 extending along a first direction, the first light source 210 and the second light source 220 are both provided with a first slide rail 150, and the first slider 201 is slidably connected to the first slide rail 150; or, the frame 100 includes a first slide rail 150 extending along a first direction, the first light source 210 and the second light source 220 are both provided with a first slider 201, and the first slider 201 is slidably connected to the first slide rail 150.

[0062] By providing a first slide rail 150 on the frame 100, the first light source 210 and the second light source 220 are both provided with a first slider 201 slidably connected to the first slide rail 150; or by providing a first slider 201 on the frame 100, the first light source 210 and the second light source 220 are both provided with a first slide rail 150 slidably connected to the slider, the risk of wear of the first light source 210 and the second light source 220 when sliding relative to the frame 100 can be reduced, and a good guiding effect can be provided for the first light source 210 and the second light source 220 sliding in the first direction.

[0063] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, the laser processing equipment 1 further includes a support frame assembly 300 , and the support frame assembly 300 has a support surface for supporting the photovoltaic assembly 2 .

[0064] The support frame assembly 300 refers to a frame 120 assembly used to support the photovoltaic assembly 2. Specifically, the support frame assembly 300 may include a plurality of support columns arranged side by side, and the top of the support column is a plane, so that the photovoltaic assembly 2 is supported by the plurality of support columns. Alternatively, the support frame assembly 300 may include a plurality of support columns and a support platform, and the support platform is connected to the plurality of support columns, and the surface of the support platform away from the support column is the support surface. Alternatively, the support frame assembly 300 may include a plurality of support platforms arranged side by side at intervals, and the surface of the support platform is the support surface.

[0065] The support surface is used to support the photovoltaic module 2. The support surface is a smooth plane or a rough surface. When the first light source 210 and the second light source 220 are both facing the film layer of the photovoltaic module 2, the support surface is arranged below the first light source 210 and the second light source 220; when the first light source 210 and the second light source 220 are both facing the side of the glass substrate of the photovoltaic module 2 away from the film layer, the first light source 210 and the second light source 220 are both located below the plane where the support surface is located.

[0066] By providing the support frame assembly 300 , the photovoltaic assembly 2 can be stably supported, thereby improving the stability of the photovoltaic assembly 2 , which is beneficial for the first light source 210 and the second light source 220 to perform a more precise marking operation on the photovoltaic assembly 2 .

[0067] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, the support frame assembly 300 includes a support seat body 310 and a transmission mechanism 320. The transmission mechanism 320 is disposed on the support seat body 310 and has a support surface. The transmission mechanism 320 extends along a second direction, and the second direction is arranged at an angle to the first direction.

The support seat body 310 can be a support platform or a plurality of support columns arranged side by side. The support seat can be made of metal or concrete. The support seat can be a movable support seat, for example, a pulley is installed at the bottom of the support seat, or the support seat can also be an immovable support seat, for example, the support seat is a support seat made of concrete.

For example, the conveying mechanism 320 may include a synchronous belt, a sprocket, or a conveying roller, etc., and may also include a driving assembly for driving the synchronous belt, the sprocket, or the conveying roller to move. The driving assembly may be a motor, a cylinder, a gear assembly, or a lead screw nut assembly, etc.

[0070] When the second direction is set at an angle with the first direction, it may mean that the second direction is set at an acute angle with the first direction, or it may mean that the second direction is set perpendicular to the first direction, or it may mean that the second direction is set at an obtuse angle with the first direction.

[0071] By providing the transmission mechanism 320 on the support seat body 310, the support seat body 310 can effectively support the transmission mechanism and the photovoltaic assembly 2 on the transmission mechanism 320, thereby improving the stability of the transmission process of the photovoltaic assembly 2. By extending the transmission mechanism 320 along the second direction, and the second direction being arranged at an angle to the first direction, the transmission mechanism 320 can drive the photovoltaic assembly 2 to move along the second direction, that is, move along the direction at an angle to the first direction, thereby changing the position of the photovoltaic assembly 2 in the second direction to change the marking position of the first light source 210 and the second light source 220 on the photovoltaic assembly 2.

[0072] Please refer to Figure 1 and Figure 3 In one embodiment of the present invention, at least two conveying mechanisms 320 are provided along the first direction; and an auxiliary support assembly 330 is also provided between at least two conveying mechanisms 320 .

[0073] The auxiliary support assembly 330 refers to an assembly for auxiliary support of the photovoltaic assembly 2. Specifically, the auxiliary support assembly 330 may include a plurality of support frames, which may be a tripod or a rectangular frame, etc. Alternatively, the auxiliary support assembly 330 may include a support table and a plurality of support frames mounted on the support table. In order to facilitate the transport of the photovoltaic assembly 2, the auxiliary support assembly 330 may also include a roller 331, which is disposed on the support frame of the auxiliary support assembly 330, so that when the photovoltaic assembly 2 is placed on the transmission mechanism and the auxiliary support assembly 330, the photovoltaic assembly 2 may contact the roller 331, so that rolling friction is formed between the photovoltaic assembly 2 and the auxiliary support assembly 330, thereby reducing the wear of the photovoltaic assembly 2 by the auxiliary support assembly 330.

[0074] By providing at least two transmission mechanisms 320 along the first direction, the support strength of the photovoltaic assembly 2 can be improved on the one hand, and the transmission power consumption of each transmission mechanism can be reduced on the other hand. By providing an auxiliary support assembly 330 between at least two transmission mechanisms, the support strength of the photovoltaic assembly 2 can be further improved.

[0075] Please refer to Figure 1 and Figure 4 In one embodiment of the utility model, the frame 100 includes a base 110 and a frame 120. The frame 120 is slidably connected to the base 110 and can slide relative to the base 110 in a second direction. The second direction is set at an angle to the first direction. The frame 120 is provided with a first light source 210 and a second light source 220.

[0076] The base 110 refers to a bearing component for bearing the entire frame 120 and the first light source 210 and the second light source 220 on the frame 120. The base 110 may be a frame structure or a block structure.

[0077] The frame 120 refers to a support frame for mounting the first light source 210 and the second light source 220. The frame 120 may be a rectangular frame, an L-shaped frame, a triangular frame, etc., as long as the first light source 210 and the second light source 220 can be mounted. The frame 120 can slide relative to the base 110, and it can be slidably connected by a slide rail or by setting a ball bearing on the base 110 to achieve the sliding effect of the two.

[0078] When the second direction is set at an angle with the first direction, it may mean that the second direction is set at an acute angle with the first direction, or it may mean that the second direction is set perpendicular to the first direction, or it may mean that the second direction is set at an obtuse angle with the first direction.

[0079] By slidably connecting the frame 120 with the base 110 and being able to slide relative to the base 110 along the second direction, the frame 120 is provided with a first light source 210 and a second light source 220. When the frame 120 slides along the second direction, it can also drive the first light source 210 and the second light source 220 to move in the second direction, thereby changing the positions of the first light source 210 and the second light source 220 in the second direction, so as to flexibly change the marking position of the photovoltaic component 2.

[0080] Please refer to Figure 1 and Figure 4 In one embodiment of the present invention, one of the base 110 and the frame 120 is provided with a second slide rail 130, and the other one is provided with a second slider 140. The second slider 140 is slidably disposed on the second slide rail 130, and the second slide rail 130 extends along the second direction.

[0081] Specifically, in one example, the seat body 110 is provided with a second slide rail 130, and the frame body 120 is provided with a second slider 140 slidably connected to the second slide rail 130. Alternatively, in another example, the seat body 110 is provided with a second slider 140, and the frame body 120 is provided with a second slide rail 130 slidably connected to the second slider 140.

[0082] By providing one of the base 110 and the frame 120 with a second slide rail 130 and the other with a second slider 140, the risk of wear of the frame 120 when sliding relative to the base 110 in the second direction can be reduced. In addition, a good guiding effect can be provided for the frame 120 to slide relative to the base 110 in the second direction.

[0083] Please refer to Figure 1 and Figure 4In one embodiment of the present invention, the base body 110 further includes a plurality of roller bodies 111 arranged along the second direction. The roller bodies 111 are rotatably disposed on the base body 110 , and the frame body 120 abuts against the roller bodies 111 .

[0084] The roller body 111 refers to a rolling body that can rotate relative to its own axis, and can be cylindrical or ball-shaped. Specifically, the roller body 111 can be arranged on the upper surface of the base body 110, or when an inverted U-shaped slide groove is provided at the bottom of the frame body 120, the roller body 111 can also be arranged on the side wall of the base body 110 to abut against the side wall of the slide groove of the frame body 120.

[0085] By providing a plurality of rollers 111 arranged along the second direction on the base 110, the frame 120 abuts against the rollers 111. When the frame 120 slides along the second direction, the friction between the frame 120 and the base 110 can form a rolling friction, thereby further reducing the friction force between the frame 120 and the base 110, so that the frame 120 can slide relative to the base 110 more smoothly in the second direction.

[0086] The utility model also proposes a photovoltaic module production line, including a laser processing device 1. The specific structure of the laser processing device 1 refers to the above-mentioned embodiment. Since the photovoltaic module production line adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0087] The above are only exemplary embodiments of the present invention, and are not intended to limit the patent scope of the present invention. All equivalent structural changes made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect applications in other related technical fields are included in the patent protection scope of the present invention.
