Description

Technical Field

[0001] This utility model relates to the field of screen cutting technology, and in particular to a traction mechanism for cutting solar screen fabric. Background Technology

[0002] As an important photovoltaic module, solar cell screens undergo a series of processes during production, including screen bonding, developing, cleaning, coating, exposure, and inspection. The screens typically consist of a frame and a steel mesh (or mesh fabric).

[0003] During the production of the screen, the mesh needs to be laser-cut according to the required size of the solar panel. However, when cutting the mesh on the platform, various factors may affect the mesh, causing it to become misaligned and resulting in more burrs after cutting, which affects the cutting effect. Utility Model Content

[0004] This utility model discloses a traction mechanism for cutting solar screen mesh, which aims to solve the technical problem that the mesh may be misaligned due to various factors when cutting the mesh on the platform surface, resulting in more burrs after cutting and affecting the cutting effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A traction mechanism for cutting solar screen mesh includes a base, a traction limiting mechanism movably connected to the base, a bottom support mechanism disposed at the center of the top of the base, and an equidistant limiting mechanism connected to the bottom support mechanism.

[0007] The traction limiting mechanism includes two X-axis brackets movably connected to the top of the base, two Y-axis brackets movably connected to the top of the base, a bearing seat fixedly connected to the top of one of the X-axis brackets, a bidirectional screw connected inside the bearing seat, a second slider movably connected to the Y-axis bracket, a handle fixedly connected to one end of the bidirectional screw, a central support plate fixedly connected to the center position of the top of the Y-axis bracket, a spring connected between the central support plate and the second slider, and a first slot disposed on the inner wall of the Y-axis bracket and the X-axis bracket.

[0008] The top inner wall of the base is provided with a plurality of first guide grooves, and the arrangement direction of the plurality of first guide grooves is respectively corresponding to the moving path of the corresponding X-axis bracket or Y-axis bracket. Each first guide groove is movably connected to a first slider, and the first slider is fixedly connected to the bottom outer wall of the X-axis bracket or Y-axis bracket.

[0009] Another X-axis bracket has a limit slide rod fixedly connected to the top outer wall, wherein two of the second sliders are symmetrically engaged with the bidirectional screw, and the other two second sliders are movably sleeved on the limit slide rod;

[0010] The top inner wall of the Y-axis bracket is provided with a second guide groove, and the bottom ends of multiple second sliders are movably connected to the second guide groove.

[0011] By incorporating a traction and limiting mechanism, the screen is placed in the first slot. Rotating the handle allows the two second sliders to move inward or outward, driving the two Y-axis supports to limit the screen's sides. The two X-axis supports clamp the screen's sides, thus limiting the screen's perimeter. With the spring mechanism, one of the X-axis supports can be pulled open during screen installation to facilitate placement. Compared to directly clamping the screen from both sides, this structure better ensures the screen does not move during traction and limiting, and avoids applying higher clamping forces to prevent damage.

[0012] In a preferred embodiment, the bottom support mechanism includes a first support rod fixed to the center of the outer wall at the top of the base, a square support block connected to the top of the first support rod, a first hinge seat disposed on the outer walls of the opposite sides of the square support block, and a support bar hinged to the first hinge seat.

[0013] The two first hinge seats are positioned in directions corresponding to the two Y-axis supports, and the top of the support bar is provided with multiple protrusions at equal intervals;

[0014] Each of the support bars has a first support block fixedly connected to its bottom outer wall, and a second slot is provided on one side inner wall of the first support block, in which a locking rod is movably engaged.

[0015] The two opposite ends of the snap-fit ​​rod are respectively supported by a first connecting rod, and the bottom end of the first connecting rod is hinged to a second hinge seat, which is fixedly connected to the top outer wall of the base.

[0016] With a bottom support mechanism, the inner wall of the bottom of the first slot is higher than the outer wall of the top of the base. This allows the square support block to provide central support for the screen, raising the support bars on both sides and expanding the support surface to support the screen. This facilitates the alignment of the first slot with the screen during clamping and positioning, reducing the difficulty of placement. Simultaneously, based on the first linkage structure, the locking rod engages with the second slot in the vertical state, providing support for the support bars. When the locking rod is lowered, both support bars can be lowered simultaneously, preventing the support bars from obstructing the path during clamping.

[0017] In a preferred embodiment, the equidistant limiting mechanism includes a circular support plate fixedly connected to the outer wall of the first support rod, a third connecting rod movably connected to the outside of the first support rod, a second connecting rod hinged to both ends of the third connecting rod, and a second support rod hinged to the other end of the second connecting rod.

[0018] A circular perforation is provided through the center of the third link, and the first support rod is located inside the circular perforation. The two second support rods are respectively connected to the bottom outer wall of the two X-axis supports.

[0019] By incorporating an equidistant limiting mechanism, the two X-axis supports clamp the screen using springs. However, the instability of the springs during clamping causes the center position of the screen to become uncontrollable. The equidistant limiting mechanism, with the first support rod as the central axis and the third link and two second links as the linkage and limiting structures, ensures that the two X-axis supports maintain equidistant movement on both sides during clamping. This safeguards the center point of the screen when clamping it, facilitating subsequent laser cutting operations.

[0020] As described above, a traction mechanism for cutting solar screen printing mesh includes a base, a traction limiting mechanism movably connected to the base, a bottom support mechanism located at the center of the top of the base, and an equidistant limiting mechanism connected to the bottom support mechanism. The traction limiting mechanism includes two X-axis supports movably connected to the top of the base, two Y-axis supports movably connected to the top of the base, a bearing seat fixedly connected to the top of one of the X-axis supports, a bidirectional screw connected within the bearing seat, a second slider movably connected to the Y-axis support, a handle fixedly connected to one end of the bidirectional screw, a central support plate fixedly connected to the center of the top of the Y-axis support, a spring connected between the central support plate and the second slider, and a first slot located on the inner wall of the Y-axis and X-axis supports. The traction mechanism for cutting solar screen printing mesh provided by this invention maintains stability during the laser cutting process of the screen printing mesh and avoids excessive clamping force on the screen printing mesh, thus preventing damage.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] The traction mechanism for cutting solar screen mesh disclosed in this utility model is mainly used in the scenario of laser cutting of solar screen mesh.

[0028] Reference Figure 1 and Figure 2 A traction mechanism for cutting solar screen mesh includes a base 1, a traction limiting mechanism 2 movably connected to the base 1, a bottom support mechanism 3 located at the center of the top of the base 1, and an equidistant limiting mechanism 4 connected to the bottom support mechanism 3.

[0029] The traction limiting mechanism 2 includes two X-axis brackets 208 movably connected to the top of the base 1, two Y-axis brackets 203 movably connected to the top of the base 1, a bearing seat 210 fixedly connected to the top of one of the X-axis brackets 208, a bidirectional screw 209 connected inside the bearing seat 210, a second slider 205 movably connected to the Y-axis bracket 203, a handle 211 fixedly connected to one end of the bidirectional screw 209, a central support plate 207 fixedly connected to the center position of the top of the Y-axis bracket 203, a spring 206 connected between the central support plate 207 and the second slider 205, and a first slot 212 disposed on the inner wall of the Y-axis bracket 203 and the X-axis bracket 208.

[0030] Reference Figure 1 and Figure 2In a preferred embodiment, the inner wall of the top of the base 1 is provided with a plurality of first guide grooves 201, and the arrangement direction of the plurality of first guide grooves 201 corresponds to the movement path of the corresponding X-axis bracket 208 or Y-axis bracket 203. A first slider 202 is movably connected in each first guide groove 201, and the first slider 202 is fixedly connected to the bottom outer wall of the X-axis bracket 208 or Y-axis bracket 203.

[0031] Reference Figure 1 and Figure 2 In a preferred embodiment, a limiting slide rod 213 is fixedly connected to the top outer wall of another X-axis bracket 208, wherein two second sliders 205 are symmetrically engaged with the bidirectional screw 209, and two other second sliders 205 are movably sleeved on the limiting slide rod 213.

[0032] Reference Figure 1 and Figure 2 In a preferred embodiment, the inner wall of the top end of the Y-axis bracket 203 is provided with a second guide groove 204, and the bottom ends of a plurality of second sliders 205 are movably connected to the second guide grooves 204. The screen is placed in the first slot 212. Under the action of the bidirectional screw 209, the two opposing Y-axis brackets 203 can move the two second sliders 205 inward or outward by rotating the handle 211, thereby driving the two Y-axis brackets 203 to provide limiting on both sides of the screen. The two opposing X-axis brackets 208 are spring-loaded. Under the retraction of 206, the two X-axis brackets 208 can clamp the two sides of the screen, thereby limiting the screen's position around its perimeter. With the spring 206 in place, one of the X-axis brackets 208 can be pulled open during screen installation to facilitate screen placement. Compared to directly clamping and fixing the screen from both sides, this structure better ensures that the screen will not move during traction and screen limiting, and does not apply higher clamping force to the screen, thus avoiding damage to the screen.

[0033] Reference Figure 4 In a preferred embodiment, the bottom support mechanism 3 includes a first support rod 303 fixed to the center of the outer wall at the top of the base 1, a square support block 301 connected to the top of the first support rod 303, a first hinge seat 302 disposed on the outer walls of the square support block 301 on both sides, and a support bar 305 hinged to the first hinge seat 302.

[0034] Reference Figure 4 In a preferred embodiment, the orientation of the two first hinge seats 302 corresponds to the orientation of the two Y-axis supports 203, and the top of the support bar 305 is provided with a plurality of protrusions 304 at equal intervals.

[0035] Reference Figure 4In a preferred embodiment, a first support block 310 is fixedly connected to the bottom outer wall of each support bar 305, and a second slot 309 is provided on one side inner wall of the first support block 310, and a locking rod 306 is movably engaged in the second slot 309.

[0036] Reference Figure 4 In a preferred embodiment, the two opposite ends of the snap-fit ​​rod 306 are respectively supported by the first connecting rod 307, and the bottom end of the first connecting rod 307 is hinged to the second hinge seat 308. The second hinge seat 308 is fixedly connected to the top outer wall of the base 1. Since the bottom inner wall of the first snap-fit ​​groove 212 is higher than the top outer wall of the base 1, the square support block 301 provides support for the screen at the center position, lifting the support bars 305 on both sides and expanding the support surface to provide support for the screen. Thus, during the process of clamping and limiting the screen, the first snap-fit ​​groove 212 can be easily aligned with the screen, reducing the difficulty of placement operation. At the same time, based on the structure of the first connecting rod 307, in the vertical state, the snap-fit ​​rod 306 is snapped into the second snap-fit ​​groove 309, which can provide support for the support bar 305. When the snap-fit ​​rod 306 is lowered, the two support bars 305 can be lowered simultaneously, which can avoid the support bars 305 from blocking the path during the clamping process.

[0037] Reference Figure 3 In a preferred embodiment, the equidistant limiting mechanism 4 includes a circular support plate 405 fixedly connected to the outer wall of the first support rod 303, a third connecting rod 403 movably connected to the outside of the first support rod 303, a second connecting rod 402 hinged to both ends of the third connecting rod 403, and a second support rod 401 hinged to the other end of the second connecting rod 402.

[0038] Reference Figure 3 In a preferred embodiment, a circular through hole 404 is provided through the center of the third connecting rod 403, and the first support rod 303 is located inside the circular through hole 404. The two second support rods 401 are respectively connected to the bottom outer walls of the two X-axis supports 208. Since the two X-axis supports 208 clamp the screen through springs 206, and the center position of the screen is uncontrolled due to the instability of the springs 206 during clamping, the equidistant limiting mechanism 4 uses the first support rod 303 as the central axis and the third connecting rod 403 and the two second connecting rods 402 as the linkage and limiting structure. This ensures that the two X-axis supports 208 always maintain equidistant movement on both sides during clamping. On the basis of the equidistant movement of the X-axis supports 208, the two related Y-axis supports 203 can also ensure equidistant movement on both sides. Thus, when clamping the screen, the center point of the screen can be guaranteed, which facilitates the subsequent laser cutting operation.

[0039] Working principle: The screen is placed in the first slot 212. Under the action of the bidirectional screw 209, the two opposing Y-axis supports 203 can move the two second sliders 205 inward or outward by rotating the handle 211, thereby limiting the two sides of the screen. The two opposing X-axis supports 208 can clamp the two sides of the screen under the retraction of the spring 206, thus limiting the screen around its perimeter. Under the action of the spring 206, one of the X-axis supports 208 can be pulled open during the installation of the screen to facilitate the placement of the screen. Compared with the method of directly clamping and fixing the screen by the two sides, this structure can better ensure that the screen will not move during the traction and limiting process, and will not apply a higher clamping force to the screen, thus avoiding damage to the screen.

[0040] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
