Description

Technical Field

[0001] The utility model relates to the field of laser equipment, in particular to a laser level pendulum module and a laser level pendulum module. Background Art

[0002] The laser transmitter module is the core component of a laser level, collectively referred to as the laser module and pendulum. The pendulum's function is to freely swing within the level within a certain range of angles and has multiple horizontal and vertical planes or axes. When the pendulum is at rest, driven by gravity or a motor, its vertical plane or axis aligns with the direction of gravity, while its horizontal plane or axis is perpendicular to it.

[0003] A laser module consists of a light-emitting component (including a control board, lamp beads, lens, housing, etc.), a conical mirror, transparent glass, and a sleeve. The axes of these components must be aligned to ensure controllable laser beam direction. Therefore, assembly and debugging of the laser module requires considerable labor.

[0004] When assembling the laser module and the pendulum, due to deviations between the machined dimensions and the theoretical dimensions, it is not possible to ensure that the laser module axis is perpendicular to the horizontal or vertical plane of the pendulum, or that the laser module axis is parallel to the horizontal or vertical axis of the pendulum. Therefore, this assembly process also requires debugging.

[0005] Therefore, the laser transmitter module needs to be debugged twice during assembly. The excessive number of components, large tolerance accumulation, and numerous steps can easily lead to product defects and operational errors. The assembly process is also time-consuming and inefficient.

[0006] like Figure 3 The structure of the second pendulum module 2 is shown in FIG. The second pendulum module 2 is a prior art, and its structure includes a second pendulum body 20, a laser module 22 and a second mounting portion 21. Figure 4 As shown, in the assembly of the laser pendulum module, the laser module 22 needs to be assembled and debugged first. During the assembly process of the laser module 22, multiple optical components such as the second light-emitting component 222, the second light-transmitting glass 223, the second conical mirror 224, etc. need to be assembled in the sleeve 221 and debugged. Then, the debugged laser module 22 is assembled on the second pendulum module 2 and fixed after debugging with the bolts 225.

[0007] During this process, the existing laser pendulum module needs to be assembled and debugged twice, which is not only time-consuming and has many steps, but also easily increases operational errors, resulting in defective products. Utility Model Content

[0008] The purpose of the present utility model is to overcome the problem in the prior art that the laser emission module needs to be assembled and debugged twice during the assembly process, which easily leads to product defects and low assembly efficiency. The utility model provides a pendulum module, which reduces the number of debugging times in the assembly process, reduces product defects and operating errors, and improves assembly efficiency and assembly accuracy.

[0009] In order to achieve the above-mentioned purpose, the utility model provides a pendulum module on the one hand, including a first pendulum body, the first pendulum body is a hollow rectangular structure, and a first mounting part body and a second mounting part body are respectively connected to two opposite surfaces of the first pendulum body, the first mounting part body is fixedly connected to the first connecting part, and the second mounting part body is connected to the second connecting part.

[0010] The pendulum module of the present application has a higher degree of integration. The integrated pendulum module can be formed in one piece during production. As far as the structure of the pendulum module is concerned, external optical components can be installed without further assembly, which streamlines the assembly process and improves assembly accuracy.

[0011] Preferably, the first mounting portion body and the second mounting portion body are respectively connected to two opposite surfaces of the three groups of the first pendulum body.

[0012] This arrangement can realize a structure of three sets of external optical components, and there are diversified options for installing the optical components.

[0013] The second aspect of the present invention provides a laser level pendulum module, including the above-mentioned pendulum module, the first mounting part body and the first connecting part are fixedly connected to form a first mounting part, the second mounting part body and the second connecting part are fixedly connected to form a second mounting part, and three groups of optical components with the same structure are installed on the three groups of first mounting parts and second mounting parts of the pendulum module.

[0014] Compared with the existing laser pendulum module, the laser level pendulum module provided by the utility model saves one assembly and one debugging, thereby improving the assembly accuracy and operation accuracy, and also improving the assembly efficiency.

[0015] Preferably, the first mounting portion is mounted with a first optical element, and the second mounting portion is mounted with a first light-emitting assembly.

[0016] A first light-emitting assembly having a light source is mounted on the second mounting portion, and a first optical element is mounted on the first mounting portion, so that light from the light source of the first light-emitting assembly passes through the second mounting portion, the first pendulum body, and the first mounting portion in sequence, and is emitted through the first optical element, thereby obtaining a desired light shape.

[0017] Preferably, the first optical element is mounted on the first connecting portion, and the first light-emitting component is mounted on the second connecting portion.

[0018] In order to achieve better light presentation effects and facilitate installation and debugging, the first optical element is installed on the first connecting portion at the end of the first mounting portion, and the first light-emitting component is installed on the second connecting portion of the second mounting portion.

[0019] Preferably, the three groups of second connecting parts are all installed with the first light-emitting components, and the three groups of first connecting parts are all installed with the first optical element.

[0020] This design enables the laser level pendulum module to have three sets of light sources and light emitting structures, which can present a more complete light space effect.

[0021] Preferably, the second connecting portion is fixedly connected to the first light-emitting component.

[0022] The second connection part is fixedly connected to the first light-emitting component with a light source. The fixed connection can be bolt pressing, gluing, welding, etc. After the first light-emitting component is adjusted in position on the corresponding fixture, it is fixed to the second connection part.

[0023] Preferably, the first light-emitting component includes a laser light source and a collimating lens arranged in sequence, so that the laser light emitted by the first light-emitting component is a collimated laser light and is emitted into the first mounting portion through the first pendulum body.

[0024] The laser light source is refracted by the collimating lens, collected and collimated, and then emitted through the first mounting portion to the first optical element. The first light-emitting component is used to emit a collimated beam of light.

[0025] Preferably, the first optical element includes a first light-transmitting glass and a first axle mirror arranged in sequence, the first light-transmitting glass is installed close to the first mounting body, and the first axle mirror is coaxially arranged with the first light-emitting component.

[0026] The first light-transmitting glass can transmit and seal the laser light, and the first conical mirror can reflect the beam light into a circle of light and emit it perpendicular to the beam light.

[0027] Preferably, the three groups of second connecting parts are all installed with the first light-emitting components, and the three groups of first connecting parts are all installed with the first optical element.

[0028] The first light-emitting assembly and the first optical element are positioned at corresponding positions on each of the three connecting sections, resulting in three circles of light emitted from the entire laser level. In actual operation, the operator will use the corresponding fixtures and jigs to determine whether the three emitted light rays are perpendicular to each other. If the three laser beams are perpendicular, debugging is complete. Once debugging is complete, the first light-emitting assembly is secured to the second connecting section, and the first light-transmitting glass and the first axicon are secured to the first connecting section.

[0029] Through the above-described technical solution, the pendulum module of the present application builds upon the existing pendulum structure by dividing the existing sleeve structure for mounting optical components into two structures: a first connecting portion 112 and a second connecting portion 122. These first and second connecting portions 112, 122 are fixedly connected to the sides of the first pendulum body, thereby forming a new integrated pendulum module. After attaching the external optical components to the pendulum module, only the assembled optical components need to be debugged. This reduces the conventional two-step assembly and debugging process to a single step, improving assembly efficiency and precision, reducing operational errors, and enhancing product quality.

[0036] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0037] In the present invention, unless otherwise specified, directional words such as "up, down, left, right, inside, outside, far, near, front" generally refer to the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and therefore cannot be understood as limitations on the present invention.

[0038] The utility model provides a pendulum module, including a first pendulum body 10, which is a hollow rectangular parallelepiped structure. A first mounting portion body 111 and a second mounting portion body 121 are respectively connected to two opposite surfaces of the first pendulum body 10. The first mounting portion body 111 is fixedly connected to a first connecting portion 112, and the second mounting portion body 121 is connected to a second connecting portion 122.

[0039] like Figure 1 As shown, the pendulum module 1 includes a first pendulum body 10 and a first mounting portion 11 and a second mounting portion 12 connected to the first pendulum body 10. The first mounting portion 11 and the second mounting portion 12 are fixedly connected to the first pendulum body 10. The first mounting portion 11 and the second mounting portion 12 are fixedly connected to the first pendulum body 10, respectively. These two fixed connections can be integrally formed, resulting in a unified pendulum body and adding two connecting portions for mounting external components. These two connecting portions can be used to mount optical components, allowing for a single assembly and commissioning of the optical components. The pendulum module 1 of the present application has a higher degree of integration. The integrated pendulum module 1 can be integrally formed during production. Due to the structure of the pendulum module 1, external optical components can be installed without further assembly, streamlining the assembly process and improving assembly accuracy. It should be noted that the structure of the first pendulum body 10 is identical to that of existing pendulums. The newly added first connecting portion 112 and the second connecting portion 122 need to be coaxially arranged to allow light from the light source to be emitted when the optical components are mounted.

[0040] Furthermore, the first mounting portion body 111 and the second mounting portion body 121 are respectively connected to two opposite surfaces of the three groups of the first pendulum body 10 .

[0041] The first pendulum body 10 is a hollow rectangular parallelepiped having six faces, of which there are three groups of opposing faces. A first mounting portion body 111 and a second mounting portion body 121 are fixedly connected to each group of opposing faces, respectively, thereby realizing a structure of three groups of external optical components, providing a variety of options for installing optical components.

[0042] The present utility model also provides a laser level pendulum module, including the above-mentioned pendulum module 1, the first mounting part body 111 and the first connecting part 112 are fixedly connected to form the first mounting part 11, the second mounting part body 121 and the second connecting part 122 are fixedly connected to form the second mounting part 12, and three groups of optical components with the same structure are installed on the three groups of first mounting parts 11 and second mounting parts 12 of the pendulum module 1.

[0043] like Figure 1As shown, the laser level pendulum module provided by the present invention utilizes the aforementioned integrated pendulum module 1, wherein the first mounting portion 11 and the second mounting portion 12 are integrally formed with the first pendulum body 10. Three sets of optical components of identical structure are mounted on each of the first mounting portion 11 and the second mounting portion 12, ensuring that the three sets of light rays radiating from the three surfaces of the pendulum module 1 are perpendicular to each other. Assembly of this laser level pendulum module requires only the installation of the optical components on the pendulum module 1 and subsequent commissioning. Compared to existing laser pendulum modules, this eliminates one assembly and commissioning step, improving assembly and operational precision, and also increasing assembly efficiency.

[0044] Furthermore, the first mounting portion 11 is mounted with a first optical element 13 , and the second mounting portion 12 is mounted with a first light-emitting assembly 14 .

[0045] Specifically, the first light-emitting assembly 14 having a light source is installed on the second mounting portion 12, and the first optical element 13 is installed on the first mounting portion 11, so that the light from the light source of the first light-emitting assembly 14 passes through the second mounting portion, the first pendulum body 10 and the first mounting portion 11 in sequence, and is emitted through the first optical element 13, thereby obtaining a desired light shape.

[0046] Furthermore, the first optical element 13 is mounted on the first connecting portion 112 , and the first light-emitting assembly 14 is mounted on the second connecting portion 122 .

[0047] In order to achieve better light presentation effects and facilitate installation and debugging, the first optical element 13 is installed at the end of the first connecting portion 112 , and the first light-emitting assembly 14 is installed inside the second connecting portion 122 .

[0048] Furthermore, the three groups of second connection parts 122 are all installed with the first light-emitting components 14 , and the three groups of first connection parts 112 are all installed with the first optical element 13 .

[0049] In order to present a more complete light and space effect, a first light-emitting component 14 with a light source is installed on the second connecting parts 122 on the three opposite surfaces of the pendulum module 1, and a first optical element 13 is installed on the first connecting part 112, so that the laser level pendulum module has three groups of light sources and a light emitting structure.

[0050] Furthermore, the second connecting portion 122 is fixedly connected to the first light-emitting component 14 .

[0051] The second connection portion 122 is fixedly connected to the first light-emitting component 14 with a light source. The fixed connection can be bolt pressing, gluing, welding, etc. After the first light-emitting component 14 is adjusted in position on the corresponding fixture, it is fixed to the second connection portion 122.

[0052] Furthermore, the first light emitting assembly 14 includes a laser light source and a collimating lens arranged in sequence, so that the laser light emitted by the first light emitting assembly 14 is a collimated laser light and is emitted into the first mounting portion 11 through the first pendulum body 10 .

[0053] Specifically, the first light-emitting assembly 14 comprises a laser light source and a collimating lens arranged in sequence along the direction from the first mounting portion 11 to the first pendulum body 10. The laser light source is refracted by the collimating lens, converged, and collimated for emission. The light then passes through the first mounting portion 11 and reaches the first optical element 13. In actual operation, the first light-emitting assembly 14 typically utilizes existing, integrated, standardized components. The first light-emitting assembly 14 is designed to emit a collimated beam of light.

[0054] Furthermore, the first optical element 13 includes a first light-transmitting glass 131 and a first axle 132 arranged in sequence. The first light-transmitting glass 131 is installed close to the first mounting body 111 , and the first axle 132 is coaxially arranged with the first light-emitting assembly 14 .

[0055] A first light-transmitting glass 131 and a first axicon 132 are sequentially installed along the direction from the first pendulum body 10 to the first connecting portion 112. Collimated laser light passes through the first light-transmitting glass 131 and is reflected by the first axicon 132, where it is transformed into a circle of light that is emitted perpendicular to the beam. The first light-transmitting glass 131 provides both light transmission and sealing protection for the laser light.

[0056] Furthermore, the three groups of second connection parts 122 are all installed with the first light-emitting components 14 , and the three groups of first connection parts 112 are all installed with the first optical element 13 .

[0057] The first light-emitting assembly 14 and the first optical element 13 are positioned at corresponding positions on each of the three connecting sections, resulting in three circles of light emitted from the entire laser level. In actual operation, the operator will use the appropriate fixtures and jigs to determine whether the three emitted light rays are perpendicular to each other. If the three laser beams are perpendicular, debugging is complete. Once debugging is complete, the first light-emitting assembly 14 is secured to the second connecting section, and the first light-transmitting glass 131 and the first axicon 132 are secured to the first connecting section 112.

[0058] It should be noted that during the debugging process of the laser optical components, Figure 2 As shown, the first light-emitting assembly must be assembled on the second connecting portion 122, and the first light-transmitting glass 131 and first axicon 132 must be mounted on the first connecting portion 112. These components must then be powered on and illuminated. Using a matching fixture and fixture, the assembler adjusts the brightness of the laser light emitted throughout the cycle to a uniform level. When the brightness of the laser light is consistent throughout the cycle, the first axicon 132 and first light-emitting assembly 14 are considered coaxial. Assembly and debugging are complete, and the optical components are then glued together.

[0059] It should be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0060] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
