Description
Technical Field
[0001] This utility model relates to the field of calibration technology for surveying and measurement equipment, and in particular to a laser adjustment device. Background Technology
[0002] In industrial manufacturing, instruments that can generate lasers are often used as tools for tasks such as ranging and calibration.
[0003] For example, when manufacturing equipment parts, laser rangefinders are used to measure the parts to ensure that the dimensions of the parts meet the design requirements. Another example is when using automated equipment to test precision parts, three-dimensional laser levels are used to calibrate and adjust multiple automated devices, so that the differences in the working environment between multiple automated devices are reduced, the gap in the testing environment between various precision parts is narrowed, and the testing accuracy is improved.
[0004] When using a three-dimensional laser level to calibrate automated equipment, if the emitted laser beam has a large linewidth, it can easily lead to large errors during measurement or calibration, exceeding the testing accuracy requirements of the automated equipment. Therefore, there is an urgent need for an adjustment device that can adjust the laser linewidth. Utility Model Content
[0005] The purpose of this invention is to provide a laser adjustment device to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0006] The solution to the technical problem of this utility model is:
[0007] A laser adjustment device, comprising:
[0008] The mounting unit has one side as the mounting side;
[0009] The adjustment unit includes a first adjustment block and a second adjustment block. The first adjustment block is installed on the side of the installation unit away from the installation side, and the second adjustment block is installed on the side of the first adjustment block. A light-emitting gap is formed between the first adjustment block and the second adjustment block.
[0010] The technical solution has at least the following beneficial effects: When manufacturing the first and second adjustment blocks, the light emission distance between the first and second adjustment blocks is preset according to the design requirements, so that the laser passing through the light emission distance can meet the design requirements of the calibration operation. When performing the calibration operation, the adjustment unit is first installed on the output end of the laser instrument through the installation unit, and then the three-dimensional laser level is started. At this time, the excessively wide laser beam is blocked by the first and second adjustment blocks, and only part of the beam is emitted from the light emission distance. The width of this part of the laser beam meets the design requirements of measurement and calibration, thereby reducing errors and meeting the accuracy requirements of equipment debugging.
[0011] As a further improvement to the above technical solution, the first adjustment block can move and be positioned on the mounting unit.
[0012] After adjusting the laser beam width at each output end of the three-dimensional laser level using multiple adjustment devices, the beams are not completely perpendicular to each other in space, affecting the debugging accuracy. The above technical solution involves moving the first adjustment block to change the plane where each light output gap is located, and aligning the laser beam with the engraving line on the worktable plane of the automated equipment, thereby making the laser beams perpendicular to each other after the line width is adjusted, thus improving the debugging and calibration accuracy.
[0013] As a further improvement to the above technical solution, the installation unit includes a first fixing plate and a second fixing plate connected to each other. A clamping gap is formed between the first fixing plate and the second fixing plate on the installation side. The side of the first fixing plate facing away from the installation side is connected to the first adjusting block. When installing the adjusting device, firstly, the first fixing plate and the second fixing plate are clamped onto both sides of the output end of the three-dimensional laser level. Then, the first fixing plate and the second fixing plate are fixed together. Finally, the adjusting unit is connected to the first fixing plate, thus completing the installation of the adjusting device. By clamping the three-dimensional laser level with the first fixing plate and the second fixing plate, the adjusting unit is stabilized on the three-dimensional laser level, eliminating the need to drill holes or install bolts on the level, reducing damage to the level. Furthermore, during disassembly, the first fixing plate and the second fixing plate can be directly disassembled to disconnect the adjusting device from the three-dimensional laser level, making the operation simple and quick.
[0014] As a further improvement to the above technical solution, the first adjusting block has an opening on the side facing the mounting side, and the second adjusting block has a mounting hole in the middle. The second adjusting block is installed on the side of the first adjusting block facing the mounting side, and the first fixing plate passes through the mounting hole and is installed at the opening. By placing the second adjusting block on the side of the first adjusting block closer to the mounting side, that is, placing the second adjusting block on the side of the first adjusting block closer to the 3D laser level, the entire adjusting device is fitted to the body of the level, reducing the outward protrusion of the adjusting device. This reduces the space occupied by the 3D laser level during automated equipment debugging, reserving operating space for workers.
[0015] As a further improvement to the above technical solution, the first adjusting block is rotatably mounted with a connecting bolt. One end of the connecting bolt, which protrudes from the first adjusting block, is threadedly connected to the first fixing plate. The connecting bolt is provided with an elastic element, one end of which is connected to the first adjusting block and the other end of which is connected to the connecting bolt. When the elastic element is in its natural state, it drives the first adjusting block to move closer to the first fixing plate.
[0016] By rotating the connecting bolts, the first adjusting block can be moved relative to the first fixed plate, thereby flexibly changing the plane where the light output gap is located, making it easier to align the laser beam with the engraved lines on the worktable. Furthermore, the elastic element provides pre-tightening force, which improves the stability of the first adjusting block relative to the first fixed plate, reduces external interference, and ensures debugging accuracy.
[0017] As a further improvement to the above technical solution, the first adjusting block is threaded with at least one adjusting bolt, one end of which protrudes from the first adjusting block and abuts against the first fixing plate. When adjusting the first adjusting block, the adjusting bolt is directly turned. After the adjusting bolt abuts against the first fixing plate, with the cooperation of the elastic element, it drives the first adjusting block to move away from or towards the first fixing plate, thereby achieving precise movement of the first adjusting block.
[0018] As a further improvement to the above technical solution, the first adjusting block is provided with a plurality of adjusting bolts spaced apart circumferentially along the connecting bolt. These multiple adjusting bolts allow the first adjusting block to move in multiple directions, enabling more precise adjustment of the laser beam.
[0019] As a further improvement to the above technical solution, the first adjusting block is rotatably mounted with at least one fixing bolt, one end of which protrudes from the first adjusting block and is threadedly connected to the first fixing plate. After the first adjusting block is moved by turning the adjusting bolt, and after it is observed that the various beams emitted by the three-dimensional laser level are perpendicular to each other in three-dimensional space, the fixing bolt is installed on the adjusting device, thereby fixing the first adjusting block and the first fixing plate together and maintaining the stability of the laser beams.
[0020] As a further improvement to the above technical solution, the first adjusting block is provided with a plurality of fixing bolts spaced apart circumferentially along the connecting bolts. These fixing bolts position the first adjusting block from multiple angles, thereby improving the stability of the first adjusting block on the first fixing plate.
[0021] As a further improvement to the above technical solution, multiple fixing bolts and multiple adjusting bolts are alternately arranged. By alternating the two types of bolts, the fixing bolts can position adjacent adjusting bolts, improving the stability of the first adjusting block on the first fixing plate and reducing the possibility of the first adjusting block loosening.

[0034] The manufacturing industry for mobile phone camera modules is becoming increasingly complex, and the requirements for mobile phone photography effects are also increasing. Therefore, manufacturers have higher and higher precision requirements when debugging camera modules. Manufacturers usually use a large number of automated equipment to test the performance of camera modules. In order to reduce the differences between automated equipment, the automated equipment is usually calibrated before testing. At this time, the staff uses a three-dimensional laser level to debug and calibrate the positional accuracy between the test fixture and the test object, ensuring that the test data of the same camera module on different automated equipment is controlled within the qualified range. The debugging and calibration is to debug and calibrate the positional accuracy between the test fixture and the test object. The specific test object is an optical drawing with a high resolution of 20,000 PPI. The frame of the drawing is a rectangular black line frame. During debugging and calibration, the laser level is used to ensure that the test fixture and the test object are simultaneously centered in the horizontal and vertical directions. However, because the laser beam of the laser level is thicker than the black line frame of the drawing, a large error occurs during debugging and calibration, exceeding the precision requirements of the automated equipment. Therefore, this application provides an adjustment device that can adjust the thickness of the laser beam emitted by the three-dimensional laser level.
[0035] Reference Figure 1 and Figure 2 This application provides a laser adjustment device, which is suitable for a three-dimensional laser level and can be installed on any laser emitting end of the three-dimensional laser level. The laser adjustment device includes:
[0036] Mounting unit 1, one side of which is the mounting side.
[0037] The adjustment unit 2 includes a first adjustment block 21 and a second adjustment block 22. The first adjustment block 21 is installed on the side of the mounting unit 1 away from the mounting side, and the second adjustment block 22 is installed on the side of the first adjustment block 21. A light-emitting gap 23 is formed between the first adjustment block 21 and the second adjustment block 22. Specifically, the cross-section of the first adjustment block 21 and the second adjustment block 22 is rectangular. Connecting protrusions are provided at the four corners of the side of the second adjustment block 22 near the first adjustment block 21. The connecting protrusions are connected to the first adjustment block 21 by bolts. The laser beam is emitted from the light-emitting gap between two adjacent connecting protrusions.
[0038] When manufacturing the first adjustment block 21 and the second adjustment block 22, the light emission distance between the first adjustment block 21 and the second adjustment block 22 is preset according to the design requirements, so that the laser passing through the light emission gap 23 can meet the design requirements of the calibration operation. When performing the calibration operation, the adjustment unit 2 is first installed on the output end of the laser instrument through the installation unit 1, and then the three-dimensional laser level is started. At this time, the excessively wide laser beam is blocked by the first adjustment block 21 and the second adjustment block 22, and only part of the beam is emitted from the light emission gap 23. The width of this part of the laser beam meets the design requirements of measurement and calibration. In this embodiment, the width of the laser beam emitted by the existing three-dimensional laser level is 2mm, while the preset width of the light emission gap 23 is 1mm. Compared with the laser beam emitted directly by the three-dimensional laser level, the laser beam limited by the light emission gap 23 greatly reduces the accuracy error of the automated equipment.
[0039] As a further preferred method, the light emission gap 23 between the second adjustment block 22 and the first adjustment block 21 can be changed by altering the height of the connecting protrusion. When debugging automated equipment with different precision requirements, the thickness of the laser beam can be changed by installing the second adjustment block 22 with a different size light emission gap 23 onto the first adjustment block 21.
[0040] The first adjustment block 21 can move and be positioned on the mounting unit 1. When the adjustment unit 2 is installed on the three-dimensional laser level, the first adjustment block 21 can move until the plane where the light output gap 23 is located is coplanar with one of the three-dimensional planes. After adjusting the laser beam width at each laser output end of the three-dimensional laser level using the adjustment device, the beams are not completely perpendicular to each other in space, which affects the debugging accuracy. By moving the first adjustment block 21, the plane where each light output gap 23 is located is changed, and the laser beams are aligned with the scribing lines on the workbench plane of the automated equipment, so that the laser beams after adjusting the line width are perpendicular to each other, thereby improving the debugging and calibration accuracy.
[0041] Reference Figure 2 The mounting unit 1 includes a first fixing plate 11 and a second fixing plate 12 connected to each other. Each of the first fixing plate 11 and the second fixing plate 12 has a clamping end at one end that is far away from each other. The two clamping ends extend in a direction that is close to each other, and a clamping gap 13 is formed between the two clamping ends on the mounting side. The side of the first fixing plate 11 that is away from the mounting side is connected to the first adjusting block 21.
[0042] As described above, when installing the adjustment device, firstly, the first fixing plate 11 and the second fixing plate 12 are clamped on both sides of the output end of the three-dimensional laser level. Then, the first fixing plate 11 and the second fixing plate 12 are fixed to each other. Finally, the adjustment unit 2 is connected to the first fixing plate 11, thus completing the installation of the adjustment device. By clamping the three-dimensional laser level with the first fixing plate 11 and the second fixing plate 12, the adjustment unit 2 is stabilized on the three-dimensional laser level. There is no need to drill holes or install bolts on the level, reducing damage to the level. At the same time, when disassembling, the first fixing plate 11 and the second fixing plate 12 can be directly disassembled to disconnect the adjustment device from the three-dimensional laser level. The operation is simple and quick.
[0043] Reference Figure 3 , Figure 4 and Figure 5 The first adjusting block 21 has an opening in the middle of the side facing the installation side, and the second adjusting block 22 has a mounting hole in the middle. The second adjusting block 22 is installed on the side of the first adjusting block 21 near the installation side. The first fixing plate 11 and the second fixing plate 12 both pass through the mounting hole and are installed at the opening position.
[0044] As described above, the first fixing plate 11 and the second fixing plate 12 are first clamped to the outermost part of the laser output end of the three-dimensional laser level. Then, the first adjusting block 21 is installed on the side of the first fixing plate 11 away from the installation side, that is, away from the three-dimensional laser level. At this time, the first adjusting plate is located on the outermost side of the three-dimensional laser level, which makes it convenient for the worker to move the first adjusting block 21, which can be moved on the installation unit 1. Then, the second adjusting block 22 is set on the side of the first adjusting block 21 close to the installation side, that is, the second adjusting block 22 is set on the side of the first adjusting block 21 close to the three-dimensional laser level. In this way, the adjusting device is fitted to the body of the level. While avoiding affecting the operator's operation of the first adjusting plate, the outward protrusion of the adjusting device is reduced, thereby reducing the space occupied by the three-dimensional laser level when debugging the automated equipment and reserving operating space for the worker.
[0045] Reference Figure 4 and Figure 5 A first mounting hole is provided at the center of the first adjusting block 21. A connecting bolt 3 is rotatably mounted in the first mounting hole. The diameter of the first mounting hole is larger than the major diameter of the connecting bolt 3, so that the connecting bolt 3 can rotate freely in the first mounting hole. One end of the connecting bolt 3 that passes through the first mounting hole is threaded to the first fixing plate 11. An elastic element 4 is sleeved on the connecting bolt 3. One end of the elastic element 4 abuts against the side of the first adjusting block 21 away from the first fixing plate 11, and the other end abuts against the end of the connecting bolt 3 away from the first fixing plate 11. When the elastic element 4 is in its natural state, it drives the first adjusting block 21 to move closer to the first fixing plate 11.
[0046] As can be seen from the above, by rotating the connecting bolt 3, the first adjusting block 21 can be moved relative to the first fixed plate 11, thereby flexibly changing the plane where the light output gap 23 is located, making it easier to align the laser beam with the scribing line on the worktable. Furthermore, the elastic element 4 provides pre-tightening force, which improves the stability of the first adjusting block 21 relative to the first fixed plate 11, reduces external interference, and ensures debugging accuracy.
[0047] The first adjusting block 21 has a second mounting hole, and at least one adjusting bolt 5 is threaded into the second mounting hole. One end of the adjusting bolt 5 protrudes from the first adjusting block 21 and abuts against the first fixing plate 11. When adjusting the first adjusting block 21, the adjusting bolt 5 is directly turned. After the adjusting bolt 5 abuts against the first fixing plate 11, it drives the first adjusting block 21 to move away from or closer to the first fixing plate 11 with the cooperation of the elastic element 4, thereby realizing the precise movement of the first adjusting block 21.
[0048] As a further preferred embodiment, the first adjustment block 21 is provided with a plurality of adjustment bolts 5 spaced apart around the connecting bolt 3. In this embodiment, the cross-section of the first adjustment block 21 is rectangular, and the plurality of adjustment bolts 5 are respectively located at the midpoints of the four sides of the rectangle. Through the plurality of adjustment bolts 5 and using the gap between the first mounting hole and the connecting bolt 3, the first adjustment block 21 is driven to move and adjust at multiple angles with the connecting bolt 3 as the center. By turning the adjustment bolts 5, the position of the first adjustment block 21 on the first fixed block can be adjusted more precisely, thereby changing the plane where the light output gap 23 is located. After the adjustment units 2 on each laser output end of the three-dimensional laser level are moved, the planes where the light output gaps 23 of each adjustment unit 2 are located are perpendicular to each other, so that the laser beams emitted by the three laser output ends through the light output gaps 23 are perpendicular to each other in three-dimensional space.
[0049] Reference Figure 3 and Figure 5 The first adjusting block 21 has a third mounting hole. A fixing bolt 6 is rotatably installed on the first adjusting block 21 at the third mounting hole. One end of the fixing bolt 6 protrudes from the first adjusting block 21 and is threaded to the first fixing plate 11. After the first adjusting block 21 is moved by turning the adjusting bolt 5, when it is observed that the various beams emitted by the three-dimensional laser level are perpendicular to each other in three-dimensional space, the fixing bolt 6 is installed on the adjusting device, thereby fixing the first adjusting block 21 and the first fixing plate 11 to each other and maintaining the stability of the laser beams.
[0050] As a further preferred embodiment, the first adjusting block 21 is provided with a plurality of fixing bolts 6 spaced apart circumferentially along the connecting bolt 3. The first adjusting block 21 is positioned from multiple angles by the plurality of fixing bolts 6, thereby improving the stability of the first adjusting block 21 on the first fixing plate 11.
[0051] As a further preferred embodiment, multiple fixing bolts 6 and multiple adjusting bolts 5 are alternately arranged circumferentially. By alternating the two types of bolts, the fixing bolts 6 can position adjacent adjusting bolts 5, thereby improving the stability of the first adjusting block 21 on the first fixing plate 11 and reducing the possibility of the first adjusting block 21 becoming loose.
[0052] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
