[0002] Photovoltaic glass converts solar energy into electrical energy and is widely used in various fields, playing a crucial role in promoting the application and development of renewable energy.

[0003] In the production and processing of photovoltaic glass, the glass needs to be placed on a workbench and the processing equipment processes the glass according to a pre-set program. Since the program is fixed, if the position of the glass panel deviates from the preset point, it will cause the processing position to shift and affect the product quality. Therefore, it is necessary to accurately place the glass in the preset position.

[0004] In the prior art, the laser light is fixed on the slide rail module for adjustment. Since the slide rail is long, it is usually equipped with two sets of horizontal slide rails and one set of vertical slide rails. The slide rail module occupies a lot of space and is difficult to install, such as CN216760135U. Utility Model Content

[0005] One of the technical problems this application aims to solve is the inconvenience of installing glass positioning equipment during the photovoltaic glass processing.

[0036] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0037] like Figures 1 to 9 As shown in the embodiments of this application, the laser positioner disclosed includes: a laser emitting component 10, an angle adjusting component 20, and a fixed base component 30. The angle adjusting component 20 includes a first mounting base structure 21 and a second mounting base structure 22. The first mounting base structure 21 and the second mounting base structure 22 are rotatably connected. The laser emitting component 10 is connected to the first mounting base structure 21. The fixed base component 30 is mounted on a worktable. The second mounting base structure 22 is movably connected to the fixed base component 30. The moving direction of the second mounting base structure 22 is parallel to the rotation axis of the first mounting base structure 21. The laser emitting component 10 is positioned facing the worktable.

[0038] Applying the technical solution of this embodiment, the fixed base assembly 30 is installed on the worktable, and the laser emitting assembly 10 emits a laser beam that irradiates the surface of the worktable. By moving the second mounting base structure 22, the laser emitting assembly 10 is moved, and the laser beam irradiation point translates along a direction parallel to the movement of the second mounting base structure 22. By rotating the first mounting base structure 21, the laser beam irradiation point moves towards or away from the fixed base assembly 30. By adjusting the positions of the first mounting base structure 21 and the second mounting base structure 22, the laser beam irradiation point can be moved across the entire worktable. This method is suitable for positioning different types of glass. During installation, only the fixed base assembly 30 needs to be installed on the worktable, making installation convenient. The technical solution of this embodiment effectively solves the problem of inconvenient installation of glass positioning equipment in the photovoltaic glass processing process of the prior art.

[0039] like Figures 1 to 3 As shown in the technical solution of this embodiment, the first side of the first mounting base structure 21 is rotatably connected to the second mounting base structure 22. The angle adjustment assembly 20 also includes a first adjustment structure 23, which is connected to the second side of the first mounting base structure 21 and the second mounting base structure 22. The first adjustment structure 23 adjusts the distance between the second side of the first mounting base structure 21 and the second mounting base structure 22. Since the first side of the first mounting base structure 21 and the second mounting base structure 22 are rotatably connected, the included angle between the first mounting base structure 21 and the second mounting base structure 22 changes during the adjustment process. The laser emitting assembly 10 is arranged parallel to the first mounting base structure 21 and perpendicular to the rotation axis of the first mounting base structure 21. When the angle between the first mounting base structure 21 and the second mounting base structure 22 increases, the irradiation point of the laser beam emitted by the laser emitting assembly 10 on the worktable moves closer to the fixed base assembly 30. When the angle between the first mounting base structure 21 and the second mounting base structure 22 decreases, the irradiation point of the laser beam emitted by the laser emitting assembly 10 on the worktable moves away from the fixed base assembly 30. Adjusting the irradiation point by rotation is convenient and easy to implement.

[0040] like Figures 1 to 3As shown, in the technical solution of this embodiment, the first adjustment structure 23 includes a first screw 231, a first elastic element 232, and a first adjustment part 233. The first screw 231 passes through the first mounting base structure 21, and the first end of the first screw 231 is connected to the second mounting base structure 22. The first adjustment part 233 has a first threaded hole that cooperates with the first screw 231. The first adjustment part 233 is sleeved on the first screw 231 and is located on the side of the first mounting base structure 21 away from the second mounting base structure 22. The first elastic element 232 is sleeved on the first screw 231 and is located between the first mounting base structure 21 and the second mounting base structure 22. The first elastic element 232 remains compressed. Rotating the first adjusting part 233 causes it to move along the axis of the first screw 231 under the action of the threaded transmission, changing the distance between the first adjusting part 233 and the first end of the first screw 231. Under the action of the first elastic element 232, the first mounting base structure 21 abuts against the end face of the first adjusting part 233, fixing the included angle between the first mounting base structure 21 and the second mounting base structure 22. Rotating the first adjusting part 233 changes the compression of the first elastic element 232, thus changing the included angle between the first mounting base structure 21 and the second mounting base structure 22. Under the action of the first elastic element 232, when the first adjusting part 233 is not rotated, the included angle between the first mounting base structure 21 and the second mounting base structure 22 remains unchanged, and no additional fixing structure is needed to prevent relative rotation. Operation is simple and adjustment is easy.

[0041] like Figure 3 As shown, in this embodiment, the first mounting base structure 21 has an opening 211, the size of which is larger than the diameter of the first screw 231, and the first screw 231 passes through the opening 211. In this embodiment, the opening 211 is a U-shaped groove to avoid interference between the first screw 231 and the first mounting base structure 21 when the first mounting base structure 21 rotates.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the first mounting base structure 21 includes a first mounting portion 212, and the second mounting base structure 22 includes a first rotating shaft 221 and a second mounting portion 222. The first rotating shaft 221 passes through the first mounting portion 212 and the second mounting portion 222. Two second mounting portions 222 are included, with the first mounting portion 212 located between the two second mounting portions 222. This prevents the first mounting portion 212 from detaching from the first rotating shaft 221 and restricts the first mounting base structure 21 from moving along the axis of the first rotating shaft 221, thus preventing a positional shift in the light emitted by the laser emitting assembly 10.

[0043] like Figure 1, Figure 2 , Figure 5 and Figure 6 As shown, in this embodiment, the second mounting base structure 22 further includes a third mounting portion 223 and a second rotating shaft 224. The second rotating shaft 224 is rotatably connected to the third mounting portion 223, and the first end of the first screw 231 is connected to the second rotating shaft 224. The first screw 231 is welded to the second rotating shaft 224. When the first adjusting portion 233 is rotated, the first screw 231 rotates along the axis of the second rotating shaft 224, preventing the first screw 231 from detaching from the opening 211 and causing structural failure.

[0044] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the fixed base assembly 30 includes a fixed base structure 31 and a second adjustment structure 32. The second adjustment structure 32 is connected to the fixed base structure 31 and to the second mounting base structure 22. The second adjustment structure 32 is used to adjust the movement of the second adjustment structure 32 on the fixed base assembly 30, thereby causing the first mounting base structure 21 and the laser emitting assembly 10 to change positions. The laser beam moves in a direction parallel to the first rotating axis 221. The first adjustment structure 23 controls the laser beam to move in a direction perpendicular to the first rotating axis 221, thereby adjusting the laser irradiation point on the worktable plane to suit the positioning of different types of photovoltaic modules.

[0045] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in the technical solution of this embodiment, the second adjustment structure 32 includes a second screw 321, a second elastic element 322, a second adjustment part 323, and a limiting part 324. The second screw 321 passes through the second mounting base structure 22. The limiting part 324 is connected to the first end of the second screw 321. The second adjustment part 323 has a second threaded hole that cooperates with the second screw 321. The second adjustment part 323 is sleeved on the second screw 321 and is located on the side of the fixed base structure 31 away from the second mounting base structure 22. The second elastic element 322 is sleeved on the second screw 321 and is located between the second mounting base structure 22 and the fixed base structure 31. Rotating the second adjusting part 323 changes the distance between the second adjusting part 323 and the first end of the second screw 321 under the action of the threaded transmission. This changes the compression of the second elastic element 322, and the second mounting base structure 22 is pressed by the second elastic element 322 and the limiting part 324. When the second adjusting part 323 stops rotating, the second mounting base structure 22 stops moving. When adjusting the second mounting base structure 22 using the above structure, only the second adjusting part 323 needs to be rotated, without any additional operation, making the operation convenient. The first adjusting part 233 and the second adjusting part 323 use wing nuts, which facilitates the operator to rotate them and adjust the position of the laser emitted by the laser emitting component 10 from two directions.

[0046] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, in this embodiment, the fixed base structure 31 includes a fourth mounting portion 33, and a second screw 321 passes through the fourth mounting portion 33. The second mounting base structure 22 includes a groove 225, which is correspondingly disposed with the fourth mounting portion 33. Along the axial direction of the second screw 321, the projection of the fourth mounting portion 33 is located inside the projection of the groove 225. The second elastic member 322 and the second adjusting portion 323 are respectively located on both sides of the fourth mounting portion 33, ensuring that the compression amount of the second elastic member 322 can be changed when the second adjusting portion 323 rotates. The groove 225 increases the movement stroke of the second mounting base structure 22, further reducing the area occupied by the entire laser positioner.

[0047] like Figure 1 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, in the technical solution of this embodiment, the second mounting base structure 22 further includes a limiting protrusion 226, and the fixed base structure 31 further includes a limiting groove 311. The limiting protrusion 226 is slidably disposed in the limiting groove 311. The limiting protrusion 226 cooperates with the limiting groove 311 to prevent the second mounting base structure 22 from detaching from the fixed base assembly 30 in the vertical direction, thus preventing structural failure.

[0048] In summary, the device mainly consists of a laser positioner (laser emitting assembly 10), a mounting base (laser lamp fixing base 11), an inclined base (first mounting base structure 21), a joint bolt (first screw 231), an adjusting nut (first adjusting part 233) I, a spring I (first elastic element 232), a pin assembly I (first rotating shaft 221), a horizontal base (second mounting base structure 22), a base plate (fixed base assembly 30), an adjusting nut II (second adjusting part 323), a square head bolt (limiting part 324 and second screw 321), a pin assembly II (second rotating shaft 224), and a spring II (second elastic element 322). The laser positioner has a cylindrical structure and can emit cross-shaped laser positioning lines. The mounting base is divided into upper and lower parts, which are connected by bolts, and a round hole is opened in the middle of the mounting base. The laser positioner is installed in the round hole and clamped by bolts. First, adjust the crosshairs of the laser positioner to ensure the lines are straight, then tighten the bolts to fix the laser positioner to the mounting base. The mounting base has a round hole, and the upper part of the tilting base has a threaded hole. Through-hole bolts connect the mounting base and the tilting base together, thus connecting the laser positioner, mounting base, and tilting base. When the tilting base is adjusted, the laser positioner adjusts accordingly. In addition to the threaded hole, the tilting base has a pin hole at one end and a groove (opening 211) at the other end for connecting with the horizontal base. The upper part of the horizontal base has four pin holes around its perimeter. The two pin holes on the left mate with the pin holes on the tilting base, and pin shaft assembly II is installed in these holes. The pin hole on the right mates with the joint bolt, connected by pin shaft assembly I. Spring I, the tilting base, and adjusting nut I are installed sequentially on the joint bolt. The joint bolt is located in the groove of the tilting base, thus connecting the tilting base and the horizontal base as one unit. The horizontal base has steps machined on both sides to mate with the base plate's slots (limiting slots 311). A round hole is machined in the center. Each side of the base plate has a slot (limiting slot 311), and a round hole perpendicular to the slot direction is designed for connection with the horizontal base. The horizontal base is installed in the slots of the base plate. A square-head bolt is installed in the round hole at the bottom of the horizontal base. The square-head bolt passes through the horizontal base, spring II, the round hole on the side of the base plate, and adjusting nut II, connecting the horizontal base to the base plate. Tightening adjusting nut I compresses spring I, causing the tilting base to rotate around the pin assembly II, reducing the tilt angle and moving the laser positioning line away. Reversing the rotation of adjusting nut I increases the tilt angle of the tilting base under the action of spring I, bringing the laser positioning line closer. Tightening adjusting nut II compresses spring II, causing the horizontal base to move horizontally, changing the horizontal position of the laser positioning line. Reversing the rotation of adjusting nut II causes the horizontal base to move in the opposite direction under the action of spring II, thus moving the laser positioning line horizontally in the opposite direction.
