Abstract
Description
Laser processing equipment and photovoltaic module production line
[0001] This application claims priority to Chinese patent application No. 202520108974.5, filed on January 17, 2025, the entire contents of which are incorporated herein by reference. Technical Field
[0002] This application relates to the field of laser processing technology, and in particular to a laser processing equipment and a photovoltaic module production line. Background Technology
[0003] Laser scribing equipment is typically used for scribing photovoltaic modules. However, related technologies use only a single light source to scribing the photovoltaic modules. When scribing photovoltaic modules with a single light source, the bottom layer of film vaporizes and is ejected, making it easy to lift up the top layer of film, resulting in an uneven surface.
[0004] Utility Model Content
[0005] The main purpose of this application is to propose a laser processing equipment and a photovoltaic module production line, which aims to improve the situation in the related technology where uneven morphology is easily formed on the thin film of the photovoltaic module when the laser processing equipment scribing lines on the photovoltaic module.
[0006] To achieve the above objectives, the laser processing equipment proposed in this application is configured to scribing lines on 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 mounted on the frame. The second light source is mounted on the frame, and the spot size of the second light source is smaller than that of the first light source. When both the first and second light sources are scribing lines on the photovoltaic module, the projections of the first light source and the second light source onto the photovoltaic module are arranged side-by-side along the first direction, and the scribing area of the first light source covers the scribing area of the second light source.
[0007] The technical solution of this application ensures the stability of the first and second light sources by placing them on a frame. By setting the light spot of the second light source to be smaller than that of the first light source, and arranging the first and second light sources side by side along a first direction, when the second light source irradiates the photovoltaic module before the first light source, the channel formed by the second light source after irradiating the photovoltaic module allows the substances generated during the vaporization of the film layer when the first light source irradiates the photovoltaic module to be released from the narrower channel. In other words, it provides an early release path for the substances generated by the vaporization of the film layer when the first light source irradiates the photovoltaic module; and the channel formed by the first light source irradiating the photovoltaic module is wider than the channel formed by the second light source irradiating the photovoltaic module.
[0008] By covering the scribing area of the second light source with the scribing area of the first 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. This can eliminate the phenomenon of film layer lifting on at least part of the photovoltaic module, improve the uneven morphology formed when the laser processing equipment irradiates the photovoltaic module, and reduce the influence of stress in this area. This reduces the risk of fracture and the impact on the film layer crystallization process on the photovoltaic module, thereby improving the service life of the photovoltaic module.
[0009] In one embodiment, the photovoltaic module includes a glass substrate and a film layer disposed on one side of the glass substrate, wherein one of the first light source and the second light source is disposed facing the film layer, and the other of the light sources is disposed facing the side of the glass substrate away from the film layer.
[0010] This configuration reduces interference from dirt on the side of the glass substrate away from the film layer on the laser, and also reduces interference from plasma on the laser, thus enabling the combination of the first and second light sources to effectively scribing lines on the photovoltaic module.
[0011] In one embodiment, the first light source is disposed facing the film layer, and the second light source is disposed facing the side of the glass substrate away from the film layer.
[0012] This setup not only improves the uneven surface but also reduces the impact of short-circuit points caused by dirt blocking the laser on laser etching, thus achieving a more effective scribing effect.
[0013] In one embodiment, both the first light source and the second light source are slidably disposed on the frame and are capable of moving relative to the frame along the first direction.
[0014] This configuration ensures that the first and second light sources slide along the first direction to draw lines on the photovoltaic module along the first direction, while also reducing the risk of damage to the photovoltaic module due to frequent movement.
[0015] In one embodiment, the frame includes a first slider extending along a first direction, and both the first light source and the second light source are provided with a first slide rail, with the first slider slidably connected to the first slide rail; or, the frame includes a first slide rail extending along a first direction, and both the first light source and the second light source are provided with a first slider, with the first slider slidably connected to the first slide rail.
[0016] This configuration reduces the risk of wear when the first and second light sources slide relative to the frame, and also provides good guidance for the sliding of the first and second light sources in the first direction.
[0017] In one embodiment, the laser processing equipment further includes a support frame assembly having a support surface configured to support the photovoltaic module.
[0018] This setup provides stable support for the photovoltaic modules, thereby improving their stability and enabling the first and second light sources to perform more precise marking operations on the photovoltaic modules.
[0019] In one embodiment, the support frame assembly includes a support base body and a conveying mechanism. The conveying mechanism is disposed on the support base body and has the support surface. The conveying mechanism extends along a second direction, which is angled to the first direction.
[0020] With this setup, the positions of the first and second light sources on the photovoltaic module can be changed by altering the position of the photovoltaic module in the second direction.
[0021] In one embodiment, at least two conveying mechanisms are provided along the first direction; an auxiliary support component is also provided between the at least two conveying mechanisms.
[0022] By providing at least two transmission mechanisms along the first direction, the support strength for the photovoltaic modules can be improved, while the transmission power consumption of each transmission mechanism can be reduced. Furthermore, by providing an auxiliary support component between the at least two transmission mechanisms, the support strength for the photovoltaic modules can be further improved.
[0023] In one embodiment, the frame includes a base and a frame, the frame being slidably connected to the base and capable of sliding relative to the base in a second direction, the second direction being at an angle to the first direction; the frame is provided with a first light source and a second light source.
[0024] With this configuration, when the frame slides along the second direction, it can also drive the first and second light sources to move in the second direction, thereby changing the positions of the first and second light sources in the second direction and flexibly changing the marking position of the photovoltaic modules.
[0025] In one embodiment, one of the base and the frame is provided with a second slide rail, and the other is provided with a second slider, the second slider being slidably disposed on the second slide rail, and the second slide rail extending along a second direction.
[0026] This design reduces the risk of wear when the frame slides relative to the base in the second direction, and also provides good guidance for the frame to slide relative to the base in the second direction.
[0027] In one embodiment, the base further includes a plurality of rollers arranged along a second direction, the rollers being rotatably mounted on the base, and the frame abutting against the rollers.
[0028] This design further reduces the friction between the frame and the base, making the frame slide more smoothly relative to the base in the second direction. Attached Figure Description

[0039] Currently, laser scribing equipment is commonly used for scribing photovoltaic (PV) modules. A PV module consists of a glass substrate and a film layer disposed 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 PV module, and the side containing the film layer is defined as the front side. Related technologies use only a single light source for scribing PV modules. However, scribing with a single light source has several drawbacks. For example, when the single light source is placed on the back side of the PV module, the back side often has a lot of dirt, which can easily block the light source, creating short-circuit points and making it difficult for the laser to reach the film layer on the front side. Conversely, when both light sources are placed on the front side of the PV module, plasma generated during etching can easily accumulate in the light path, blocking the light from reaching the film layer. In addition, when a single light source is used, regardless of whether it is placed on the back or front side of the photovoltaic module, since the photovoltaic module consists of multiple thin films, the layer closest to the glass substrate 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 ejection manner, which causes the thin film away from the glass substrate to be flipped up, thus easily forming an uneven topography.
[0040] In order to improve the situation where uneven morphology is easily formed on the thin film of photovoltaic modules when laser processing equipment scribing lines on photovoltaic modules in related technologies, this application proposes a laser processing equipment.
[0041] Referring to Figures 1 and 2, in one embodiment of this application, the laser processing equipment 1 is configured to scribing lines on a photovoltaic module 2 along a first direction. The laser processing equipment 1 includes a frame 100, a first light source 210, and a second light source 220. The first light source 210 is mounted on the frame 100. The second light source 220 is mounted 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 both the first light source 210 and the second light source 220 are scribing lines on the photovoltaic module 2, the projections of the first light source 210 and the second light source 220 on the photovoltaic module 2 are arranged side-by-side along the first direction, and the scribing area of the first light source 210 covers the scribing area of the second light source 220.
[0042] The frame 100 refers to the frame assembly 120 configured to mount the first light source 210 and the second light source 220. The frame 100 may include a column and a crossbeam connected to the column, with the first light source 210 and the second light source 220 mounted on the crossbeam. Alternatively, the frame 100 may include a base and an extension arm connected to the base, with the first light source 210 and the second light source 220 mounted on the extension arm. Or, the frame 100 may include a first crossbeam, a second crossbeam, and a support connecting the first and second crossbeams, with the first light source 210 mounted on the first crossbeam and the second light source 220 mounted on the second crossbeam, etc. Any configuration that facilitates the mounting of the first light source 210 and the second light source 220 is acceptable.
[0043] The first light source 210 is configured to emit laser light, thereby enabling it to scribing and etching the film layer on the glass substrate of the photovoltaic module 2. When the first light source 210 is mounted on the frame 100, it can be connected to the frame 100 by means of threaded connection, snap-fit connection, welding or bonding.
[0044] The second light source 220 is configured to emit laser light, thereby enabling it to scribing and etching the film layer on the glass substrate of the photovoltaic module 2. When the second light source 220 is mounted on the frame 100, it can also be connected to the frame 100 by means of threaded connection, snap-fit connection, welding or bonding.
[0045] In this application, the light spot refers to the spot formed when a laser beam illuminates the illumination surface of the photovoltaic module 2, and this spot can be circular or elliptical, etc. Specifically, the light spot of the first light source 210 refers to the spot formed when the laser beam emitted by the first light source 210 illuminates the illumination surface of the photovoltaic module 2. The light spot of the second light source 220 refers to the spot formed when the laser beam emitted by the second light source 220 illuminates the illumination surface of the photovoltaic module 2.
[0046] The size of the light spot refers to the diameter of the light spot formed by the laser beam illuminating the surface of the photovoltaic module 2. In this application's technical solution, the difference between the second light source 220 and the first light source 210 is that the light spot of the second light source 220 is smaller than that of the first light source 210. That is, the diameter of the light spot illuminating the photovoltaic module 2 by the second light source 220 is smaller than the diameter of the light spot illuminating the photovoltaic module 2 by the first light source. This arrangement results in a smaller line width on the photovoltaic module 2 created by the second light source 220 compared to the line width created by the first light source 210.
[0047] The first light source 210 and the second light source 220 in the laser processing equipment 1 are configured to scribble lines on the photovoltaic module 2 along a first direction. Specifically, the first light source 210 and the second light source 220 in the laser processing equipment 1 can move along the first direction while the photovoltaic module 2 remains stationary; or, the first light source 210 and the second light source 220 in the laser processing equipment 1 can remain stationary while the photovoltaic module 2 moves in a direction opposite to the first direction. Specifically, when the photovoltaic module 2 remains stationary while the first light source 210 and the second light source 220 move along the first direction, the second light source 220 is located at the front end of the first light source 210, and the second light source 220 always scribbles lines on the photovoltaic module 2 along the first direction before the first light source 210. When the photovoltaic module 2 moves in a direction opposite to the first direction, while the first light source 210 and the second light source 220 remain stationary, the second light source 220 can be positioned on one side of the first light source 210 along the first direction. In order to draw a line on the photovoltaic module 2 along the first direction, the photovoltaic module 2 will move away from the first direction relative to the first light source 210 and the second light source 220. The photovoltaic module 2 is first irradiated by the second light source 220, which forms a narrower channel on the photovoltaic module 2. Then, the first light source 210 is irradiated, which forms a wider channel on the photovoltaic module 2. When both the first light source 210 and the second light source 220 are scribing lines on the photovoltaic module 2, the projections of the first light source 210 and the second light source 220 on the photovoltaic module 2 are arranged side by side along the first direction. Regardless of whether the first light source 210 and the second light source 220 move or the photovoltaic module 2 moves, the second light source 220 will scribing lines on the photovoltaic module 2 before the first light source 210. In the direction of scribing lines on the photovoltaic module 2, the second light source 220 will irradiate the photovoltaic module 2 first, forming a narrower groove on the photovoltaic module 2. Then, the first light source 210 will irradiate the photovoltaic module 2 and form a wider groove on the photovoltaic module 2. This allows the wider groove to cover the narrower groove and can cover and at least partially eliminate the uneven morphology formed when the second light source 220 irradiates the photovoltaic module 2, thereby improving the problem of uneven morphology easily formed when the laser processing equipment 1 scribes lines on the photovoltaic module 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 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 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 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 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 scribed area of the first light source 210 on the photovoltaic module 2 covers the scribed area of the second light source 220.
[0048] The technical solution of this application ensures the stability of the first light source 210 and the second light source 220 by placing them on the frame 100. By setting the light spot of the second light source 220 to be smaller than that of the first light source 210, and arranging the first light source 210 and the second light source 220 side by side along the first direction, when the second light source 220 irradiates the photovoltaic module 2 before the first light source 210, the channel formed by the second light source 220 after irradiating the photovoltaic module 2 allows the substances generated during the vaporization of the film layer when the first light source 210 irradiates the photovoltaic module 2 to be released from the narrower channel. In other words, it provides an earlier release path for the substances generated by the vaporization of the film layer when the first light source 210 irradiates the photovoltaic module 2; and the channel formed by the first light source 210 irradiating the photovoltaic module 2 is wider than the channel formed by the second light source 220 irradiating the photovoltaic module 2. By covering the scribing area of the second light source 220 with the scribing area of the first light source 210, the narrower channel formed by the second light source 220 irradiating the photovoltaic module 2 can be supplemented and covered by the wider channel formed by the first light source 210 irradiating the photovoltaic module 2. This can eliminate the phenomenon of film layer lifting on at least part of the photovoltaic module 2, improve the uneven morphology formed when the laser processing equipment 1 irradiates the photovoltaic module 2, and reduce the influence of stress at this point, thereby reducing the risk of fracture at this point and the impact on the film layer crystallization process in the photovoltaic module 2, thus improving the service life of the photovoltaic module 2.
[0049] Referring to Figures 1 and 2, in one embodiment of this application, the photovoltaic module 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 facing the film layer, and the other is disposed facing the side of the glass substrate away from the film layer.
[0050] Typically, a photovoltaic module 2 has two opposing surfaces. The front surface of the photovoltaic module 2 can be the surface with a film layer, and the back surface is a glass substrate. The back surface of the photovoltaic module 2 usually contacts the conveyor platform of the production line, and therefore often accumulates dirt, which can easily obstruct the laser light source. This application reduces the interference of dirt on the scribing of the photovoltaic module 2 by aligning one of the first light source 210 and the second light source 220 towards the film layer.
[0051] In addition, it is understood that plasma is generated when the film layer is vaporized. By pointing one 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 module 2 can be reduced.
[0052] By setting 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, the interference of dirt on the side of the glass substrate away from the film layer on the laser can be reduced on the one hand, and the interference of plasma on the laser can be reduced on the other hand. Thus, the cooperation of the first light source 210 and the second light source 220 can effectively scribing lines on the photovoltaic module 2.
[0053] Referring to Figures 1 and 2, in one embodiment of this application, the first light source 210 is disposed toward the film layer, and the second light source 220 is disposed toward the side of the glass substrate away from the film layer.
[0054] By setting the first light source 210 towards the film layer and the second light source 220 towards the side of the glass substrate away from the film layer, the second light source 220 first scribing lines on the photovoltaic module 2 to create a narrower groove. Then, when the first light source 210 scribing lines on the photovoltaic module 2, it can not only cover the narrower groove formed by the second light source 220 irradiating the photovoltaic module 2 and improve the uneven morphology, but also supplement the scribing of the areas where the light irradiated by the second light source 220 is blocked by dirt. This reduces the impact of short circuit points formed by dirt blocking the laser on laser etching, thereby achieving a more effective scribing effect.
[0055] As shown in Figure 1, in one embodiment of this application, 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 in a first direction.
[0056] When the first light source 210 and the second light source 220 are slidably disposed on the frame 100, a drive device can be configured to drive the first light source 210 and the second light source 220 to move in a first direction. For example, the drive assembly can be a linear motor, a cylinder, or driven by a lead screw and nut assembly. Of course, without considering automation, the first light source 210 and the second light source 220 can also be manually operated to move relative to the frame 100 in the first direction.
[0057] By sliding both the first light source 210 and the second light source 220 onto the frame 100, it is possible to ensure that the first light source 210 and the second light source 220 slide along the first direction to draw lines on the photovoltaic module 2 along the first direction. On the other hand, it is also possible to reduce the risk of damage to the photovoltaic module 2 due to frequent movement.
[0058] As shown in Figure 1, in one embodiment of this application, the frame 100 includes a first slider 201 extending along a first direction, and both the first light source 210 and the second light source 220 are provided with a first slide rail 150, with the first slider 201 slidably connected to the first slide rail 150; or, the frame 100 includes a first slide rail 150 extending along a first direction, and both the first light source 210 and the second light source 220 are provided with a first slider 201, with the first slider 201 slidably connected to the first slide rail 150.
[0059] By providing a first slide rail 150 on the frame 100, and providing a first slider 201 that is slidably connected to the first slide rail 150 for both the first light source 210 and the second light source 220; or by providing a first slider 201 on the frame 100, and providing a first slide rail 150 that is slidably connected to the slider for both the first light source 210 and the second light source 220, the risk of wear when the first light source 210 and the second light source 220 slide relative to the frame 100 can be reduced. In addition, it can also provide a good guiding effect for the sliding of the first light source 210 and the second light source 220 in the first direction.
[0060] Referring to Figures 1 and 3, in one embodiment of this application, the laser processing equipment 1 further includes a support frame assembly 300, which has a support surface configured to support the photovoltaic module 2.
[0061] The support frame assembly 300 refers to the frame 120 assembly configured to support the photovoltaic module 2. Specifically, the support frame assembly 300 may include multiple support columns arranged side by side, the top of which is a flat surface, thereby supporting the photovoltaic module 2. Alternatively, the support frame assembly 300 may include multiple support columns and support platforms, the support platforms being connected to the multiple support columns, with the surface of the support platform facing away from the support columns serving as the support surface. Alternatively, the support frame assembly 300 may include multiple support platforms arranged side by side at intervals, with the platform surface of the support platform serving as the support surface.
[0062] The support surface is configured to support the photovoltaic module 2. This support surface can be a smooth plane or a rough surface, etc. When both the first light source 210 and the second light source 220 are facing the film layer of the photovoltaic module 2, the support surface is located below the first light source 210 and the second light source 220; when both the first light source 210 and the second light source 220 are facing the side of the glass substrate of the photovoltaic module 2 away from the film layer, both the first light source 210 and the second light source 220 are located below the plane containing the support surface.
[0063] By setting up the support frame assembly 300, the photovoltaic module 2 can be stably supported, thereby improving the stability of the photovoltaic module 2. This, in turn, allows the first light source 210 and the second light source 220 to perform more precise marking operations on the photovoltaic module 2.
[0064] Referring to Figures 1 and 3, in one embodiment of this application, the support frame assembly 300 includes a support base body 310 and a conveying mechanism 320. The conveying mechanism 320 is disposed on the support base body 310 and has a supporting surface. The conveying mechanism 320 extends along a second direction, which is set at an angle to the first direction.
[0065] The support body 310 is a key component configured to support the conveying mechanism 320 and the optical valley components on the conveying mechanism 320. The support body 310 can be a support platform or multiple support columns arranged side-by-side. The support can be made of metal or concrete, etc. The support can be movable, for example, with pulleys installed at the bottom, or it can be immovable, for example, a concrete support.
[0066] The conveying mechanism 320 refers to a mechanism configured to move an object (e.g., a photovoltaic panel assembly) disposed on the conveying mechanism 320. For example, the conveying mechanism 320 may include a timing belt, sprocket, or conveyor roller, and may also include a drive assembly for driving the timing belt, sprocket, or conveyor roller. The drive assembly may be a motor, cylinder, gear assembly, or lead screw and nut assembly, etc.
[0067] When the second direction is set at an angle to the first direction, it can mean that the second direction is set at an acute angle to the first direction, or it can mean that the second direction is set perpendicular to the first direction, or it can mean that the second direction is set at an obtuse angle to the first direction.
[0068] By mounting the transmission mechanism 320 on the support body 310, the support body 310 can effectively support the transmission mechanism and the photovoltaic module 2 on the transmission mechanism 320, thereby improving the stability of the photovoltaic module 2 during transmission. By extending the transmission mechanism 320 along a second direction at an angle to the first direction, the transmission mechanism 320 can drive the photovoltaic module 2 to move along the second direction, i.e., along a direction at an angle to the first direction. This changes the position of the photovoltaic module 2 in the second direction, thereby changing the marking positions of the first light source 210 and the second light source 220 on the photovoltaic module 2.
[0069] Referring to Figures 1 and 3, in one embodiment of this application, at least two conveying mechanisms 320 are provided along a first direction; an auxiliary support component 330 is also provided between the at least two conveying mechanisms 320.
[0070] The auxiliary support assembly 330 refers to an assembly configured to provide auxiliary support for the photovoltaic module 2. Specifically, the auxiliary support assembly 330 may include multiple support frames, such as tripods or rectangular frames. Alternatively, the auxiliary support assembly 330 may include a support platform and multiple support frames mounted on the support platform. To facilitate the transfer of the photovoltaic module 2, the auxiliary support assembly 330 may also include rollers 331. The rollers 331 are mounted on the support frames of the auxiliary support assembly 330, so that when the photovoltaic module 2 is placed on the transmission mechanism and the auxiliary support assembly 330, the photovoltaic module 2 can contact the rollers 331, thereby creating rolling friction between the photovoltaic module 2 and the auxiliary support assembly 330, thus reducing wear on the photovoltaic module 2 caused by the auxiliary support assembly 330.
[0071] By providing at least two transmission mechanisms 320 along the first direction, the support strength for the photovoltaic module 2 can be improved, and the transmission power consumption of each transmission mechanism can be reduced. By providing an auxiliary support component 330 between the at least two transmission mechanisms, the support strength for the photovoltaic module 2 can be further improved.
[0072] Referring to Figures 1 and 4, in one embodiment of this application, 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, which 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.
[0073] The base 110 refers to the load-bearing component configured to support the entire frame 120 and the first light source 210 and the second light source 220 on the frame 120. The base 110 can be a frame structure or a block structure, etc.
[0074] The frame 120 refers to the support frame configured to mount the first light source 210 and the second light source 220. The frame 120 can be a rectangular frame, an L-shaped frame, or a triangular frame, as long as it can accommodate the first light source 210 and the second light source 220. The frame 120 is slidable relative to the base 110. It can be slidably connected by a slide rail and slider, or the sliding effect can be achieved by setting ball bearings on the base 110.
[0075] When the second direction is set at an angle to the first direction, it can mean that the second direction is set at an acute angle to the first direction, or it can mean that the second direction is set perpendicular to the first direction, or it can mean that the second direction is set at an obtuse angle to the first direction.
[0076] By slidably connecting the frame 120 to the base 110 and allowing it to slide relative to the base 110 in a second direction, and by providing a first light source 210 and a second light source 220 on the frame 120, the frame 120 can also drive the first light source 210 and the second light source 220 to move in the second direction when it slides in the second direction, thereby changing the position of the first light source 210 and the second light source 220 in the second direction and flexibly changing the marking position of the photovoltaic module 2.
[0077] Referring to Figures 1 and 4, in one embodiment of this application, one of the base 110 and the frame 120 is provided with a second slide rail 130, and the other 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 a second direction.
[0078] Specifically, in one example, a second slide rail 130 is provided on the base 110, and a second slider 140 is provided on the frame 120 that is slidably connected to the second slide rail 130. Alternatively, in another example, a second slider 140 is provided on the base 110, and a second slide rail 130 is provided on the frame 120 that is slidably connected to the second slider 140.
[0079] By providing a second slide rail 130 to one of the base 110 and the frame 120, and a second slider 140 to the other, the risk of wear when the frame 120 slides relative to the base 110 in the second direction can be reduced. In addition, it can also provide a good guiding effect for the sliding of the frame 120 relative to the base 110 in the second direction.
[0080] Referring to Figures 1 and 4, in one embodiment of this application, the base 110 further includes a plurality of rollers 111 arranged along a second direction. The rollers 111 are rotatably disposed on the base 110, and the frame 120 abuts against the rollers 111.
[0081] Roller 111 refers to a rolling element that can rotate relative to its own axis, and can be cylindrical or ball-bearing. Specifically, roller 111 can be provided on the upper surface of base 110, or when the bottom of frame 120 has an inverted U-shaped groove, roller 111 can also be provided on the side wall of base 110 and configured to abut against the side wall of the groove of frame 120.
[0082] By providing multiple rollers 111 arranged along the second direction on the base 110, and the frame 120 abutting against the rollers 111, when the frame 120 slides along the second direction, the friction between the frame 120 and the base 110 can be made into rolling friction, thereby further reducing the friction between the frame 120 and the base 110, thus making the frame 120 slide more smoothly relative to the base 110 in the second direction.
[0083] This application also proposes a photovoltaic module production line, including a laser processing equipment 1. The specific structure of the laser processing equipment 1 is as described in the above embodiments. Since this photovoltaic module production line adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
[0084] The above are merely exemplary embodiments of this application and do not limit the patent scope of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
