Description

Technical Field

[0001] This invention relates to the field of laser measurement technology, specifically to a laser measurement device for aluminum material production. Background Technology

[0002] On the metal processing production line for battery casings, pre-cutting surveying is required before aluminum material processing to ensure processing accuracy, uniform thickness of the battery casing, and explosion-proof performance. For example, the railway track-setting and aligning laser measuring instrument (application number CN200910015897.4) discloses such an instrument, comprising a laser emitting device, a measuring device, a monitoring and correction device, and three traveling trolleys. The laser emitting device, measuring device, and monitoring and correction device are each mounted on a traveling trolley. Wireless communication devices are installed on all three devices, enabling wireless communication. The laser emitting device includes a track-setting laser, a track-aligning laser, a laser processor, and a touchscreen. The measuring device and monitoring and correction device include an optical imaging system, a CCD sensor, a measuring processor, a touchscreen, and a level sensor. This invention uses laser as a reference line and measures the laser position through an optical system and a CCD sensor, solving the problem of measuring the amount of track lifting and shifting of long-distance (over 200m) rails by railway engineering departments. It can perform high-precision detection of railway line smoothness, providing a reliable measurement basis for railway maintenance with high measurement accuracy.

[0003] However, the aforementioned technical solution, when applied to laser measurement of materials, suffers from significant errors due to its reciprocating, single-shot laser transmission and reception method. According to the principles of laser measurement, after the laser beam is emitted, it is received by a receiver after undergoing special filtering. The distance between two points is calculated using an algorithm based on the time interval between transmission and reception. The reciprocating transmission and reception method results in a very short laser path and a very short time interval, leading to large time errors and low accuracy.

[0004] In summary, the technical problem addressed by this invention is that the existing laser mapping method has too low measurement accuracy for the processing and mapping of metal parts, which leads to processing errors in subsequent aluminum processing and affects the quality of aluminum forming. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a laser measuring device for aluminum production, which solves the problems mentioned in the background art.

[0013] Preferably, a dust-proof sealing ring is installed on the side of the linear guide trolley to seal the integrated guide rail, ensuring that the linear guide trolley does not shake during movement and reducing the impact of movement vibration on laser measurement. The gantry trolley is then started and slides on the gantry guide rail, emitting a laser beam at an angle through a second laser generator mounted on it. The beam is reflected off the aluminum material at the lower end and received by a corresponding second receiver. The reflection angle and time difference data are then transmitted via a wiring harness at the upper end of the second laser generator to the integrated control box for calculation, obtaining the thickness data of the aluminum material measured from directly above.

[0014] Preferably, the side-mounted mapping unit includes: a mapping machine housing, a laser guide tube, a shock-absorbing rubber pad, a mapping algorithm chip, a first receiver mounting bracket, a light sensor, and a second receiver; the lower end of the mapping machine housing is provided with a shock-absorbing rubber pad, the lower end of which is mounted on the upper surface of the linear guide vehicle; the upper end of the mapping machine housing is fixedly mounted with a laser guide tube to protect against external light interference and improve laser quality.

A surveying algorithm chip is arranged at the rear end of the second receiver, and a first receiver mounting bracket is arranged at the rear end of the second receiver.

[0015] Preferably, an adjustment component bracket is provided at the lower end of the inside of the surveying machine housing to stably support the laser calibration component, and a high-speed silent motor is fixedly installed on the side of the laser calibration component.

[0016] Preferably, a laser is emitted from the first laser generator at the top of the side-mounted surveying unit, passes through a laser guide tube, and enters the laser calibration assembly. The laser calibration assembly adjusts and converts the single-point beam into a scanning beam. During the scanning, a photosensor detects the beam and records the emission time. When the laser is reflected and received by the second receiver, the interval is calculated. To distinguish the scanned laser beams, the frequency of the optical fiber is cyclically changed during each emission period, ensuring that the thickness and top-view dimensions of the aluminum material are measured.

[0017] Preferably, the laser calibration component includes: a calibration component housing, a motor shaft, a reflective prism frame, and a reflective prism. The calibration component housing is fixedly mounted on an adjustment component bracket, and the adjustment component bracket is integrally connected to the upper laser guide tube.

[0020] Preferably, the laser emitted by the first laser generator enters the housing of the calibration component through the laser guide tube, and then the high-speed silent motor installed on one side of the housing of the calibration component is started, so that the motor shaft inside the housing of the calibration component can rotate, and the reflective prism installed on it can rotate synchronously, thereby continuously changing the reflection angle of the laser emitted from above. The reflected laser light is continuously swept across a parallel light lens on one side. The refractive index of the processed parallel light lens converts all the swept laser light into parallel light, refracting the reflected laser light into parallel light, which is then emitted from the laser guide groove. The frequency of the laser sweep depends on the rotation speed of the high-speed silent motor. Using this method, laser measurement can ensure that data can be mapped from the side of aluminum materials of different thicknesses within the measurement range.

[0021] This invention provides a laser measuring device for aluminum material production. It has the following advantages: (1) In this invention, the gantry surveying component is slidably set on an integrated guide rail to transport the uncut aluminum material from the electric conveyor roller to the horizontal grid plate and place it stably. Then, the gantry surveying component moves on the integrated guide rail to survey the aluminum material. The refraction transmission and reception method is used to increase the laser path and reduce the error of time monitoring. After completion, the lifting cylinder is activated to lift the lifting conveyor belt to lift the aluminum material for unloading, and then it is processed. (2) The present invention uses a dust-proof sealing ring set on the side of the linear guide car to seal the dust on the integrated guide rail, ensuring that the linear guide car does not shake when it moves, and reducing the impact of movement vibration on laser measurement. Then, the gantry moving car is started and slides on the gantry guide rail. The laser is emitted at an angle by the second laser generator installed on it and reflected on the aluminum material at the lower end. It is received by the corresponding second receiver. Then, the reflection angle and time difference data are transmitted to the integrated electrical control box through the wire bundle at the upper end of the second laser generator for calculation, so as to obtain the thickness data of the aluminum material measured from directly above. (3) In this invention, a laser is emitted from the first laser generator at the top of the side-mounted mapping unit. The laser passes through the laser guide tube and enters the laser calibration assembly. The laser calibration assembly adjusts and converts the single-point beam into a light beam for scanning. When the light beam is scanned, it is detected by the light sensor and the emission time is recorded. When the laser is reflected and received by the third receiver, the interval time is calculated. In order to distinguish the scanned laser, the frequency of the optical fiber is changed cyclically during each emission period to ensure that the thickness and top-view dimensions of the aluminum material are measured. (4) The laser emitted by the first laser generator enters the housing of the calibration component through the laser guide tube, and then the high-speed silent motor installed on one side of the housing of the calibration component is started, so that the motor shaft inside the housing of the calibration component can rotate and the reflective prism installed on it can rotate synchronously, so that the reflection angle of the laser emitted from above can be continuously changed. (5) In this invention, the laser reflected by the reflecting prism continuously sweeps across a parallel light lens on one side. The refractive index of the processed parallel light lens converts all the sweeping laser light into parallel light, refracting the reflected laser light into parallel light, which is then emitted from the laser guide groove. The frequency of the laser sweep depends on the rotation speed of the high-speed silent motor. By performing laser measurement using the above scheme, it is possible to ensure that the side surfaces of aluminum materials of different thicknesses are all mapped by laser within the measurement range.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] like Figures 1 to 2 As shown, this embodiment of the invention provides a laser measuring device for aluminum production, including a device transport base plate 1 and an integrated guide rail 2 mounted on the side of the device transport base plate 1. An electric transport roller 5 is provided in the middle of the device transport base plate 1, and a dust removal air curtain machine 4 is provided at the feeding end of the device transport base plate 1. A gantry surveying component 3 for mobile surveying is slidably arranged on the integrated guide rail 2.

[0026] The reason why an integrated guide rail 2 is used instead of a spliced ​​one is that a large amount of metal powder will be generated on the production line of metal parts, which can easily accumulate at the splicing points and affect the smoothness of the integrated guide rail 2. In addition, the dust removal air curtain machine 4 will also perform dust removal treatment on the surface of the aluminum material before the aluminum material enters the surveying position.

[0027] In this embodiment, a horizontal grid plate 6 is provided on the upper surface of the equipment transport base plate 1 and on one side of the electric transport roller 5. The horizontal grid plate 6 is adjusted to ensure that all plate surfaces are on the same horizontal plane. A lifting conveyor belt 8 is provided in the slot of the horizontal grid plate 6 at the upper end of the equipment transport base plate 1. A lifting cylinder 7 is provided at the lower end of the equipment transport base plate 1. A bracket is provided at the output end of the lifting cylinder 7 and the bracket is connected to the drive roller of the lifting conveyor belt 8. The drive source harness of the lifting conveyor belt 8 is always connected to the power supply equipment to ensure the power supply of the lifting conveyor belt 8 during the movement.

[0028] A laser calibration mirror 9 is installed at the upper end of the equipment transport base plate 1 and in the empty groove of the horizontal grid plate 6. The laser calibration mirror 9 is flush with the horizontal grid plate 6. A positioning sensor 10 is installed in the middle of the laser calibration mirror 9 for laser positioning calibration. The positioning sensor 10 is an existing photoelectric sensor, and the model can be selected as needed.

[0029] It should be noted that the gantry surveying component 3 is slidably mounted on the integrated guide rail 2, transporting the uncooked aluminum material from the electric conveyor roller 5 to the horizontal grid plate 6 for stable placement. Subsequently, the gantry surveying component 3 moves along the integrated guide rail 2 to survey the aluminum material, employing a refraction-based transmission and reception method to increase the laser path and reduce time monitoring errors. After completion, the lifting cylinder 7 is activated, lifting the lifting conveyor belt 8 to lift the aluminum material for unloading, followed by processing.

[0030] like Figure 1 , Figures 3 to 4 As shown, the gantry mapping component 3 includes: a linear guide carriage 301, a side mapping unit 302, a laser calibration component 303, an adjustment knob 304, a laser generator bracket 305, and a first laser generator 306. The linear guide carriage 301 is slidably mounted on the integrated guide rail 2. The side mapping unit 302 is fixedly mounted on the linear guide carriage 301. The laser generator bracket 305 is mounted on the upper surface of the side mapping unit 302. The first laser generator 306 is fixedly mounted on the upper end of the laser generator bracket 305. The laser calibration component 303 is located at the outer end of the side mapping unit 302, used to adjust the laser beam point into a laser line. The adjustment knob 304 is located at the outer end of the laser calibration component 303. The adjustment knob 304 adopts a variable resistance regulator, which can control the speed of the high-speed audio-visual motor.

[0031] It should be noted that a gantry rail 307 is fixedly installed between the side surveying units 302, and a gantry trolley 308 is slidably mounted on the gantry rail 307. An integrated electrical control box 309 is fixedly installed on the upper end of the gantry trolley 308. The integrated electrical control box 309 integrates a PLC electrical control module, a wireless transmission module, and a surveying and computing chip. The PLC electrical control system is used to control various electrical devices, and the wireless transmission system is used to integrate the data calculated by the surveying and computing chip and upload it to the cloud server inside the machining center for subsequent use by the processing equipment.

[0032] In this embodiment, the gantry mobile vehicle 308 has several generator expansion brackets 310 on its side. Each generator expansion bracket 310 has a second laser generator 311 fixedly installed at its outer end. The second laser generator 311 is connected to the integrated electrical control box 309 via a wiring harness. The lower end of the gantry mobile vehicle 308 has several second receivers 312 corresponding to the second laser generators 311. Both the first laser generator 306 and the second laser generator 311 are WXS-J series models.

[0033] The integrated guide rail 2 is sealed with a dust-removing sealing ring on the side of the linear guide rail 301 to prevent dust from entering the linear guide rail 301 during movement, thus reducing the impact of vibration on laser measurement. The gantry moving car 308 then slides on the gantry guide rail 307, where a second laser generator 311 emits a laser beam at an angle. The beam is reflected off the aluminum material at the lower end and received by the corresponding second receiver 312. The reflection angle and time difference data are then transmitted via a wire harness at the upper end of the second laser generator 311 to the integrated control box 309 for calculation. The calculation rules use the time difference and reflection angle to determine the laser propagation distance. Combined with trigonometric formulas, the vertical data is calculated to obtain the thickness of the aluminum material measured from directly above. It should be noted that the laser transmitting and receiving positions are on the same reference plane. The logic of the calculation program is as follows: let the path distance obtained from the time difference be X, let the laser reflection angle be α, and the vertical distance, which is the final data to be measured, be Y. Then the calculation formula is Y = (X / 2) * COS(α / 2), thus obtaining the final result.

[0034] like Figure 1 , Figure 3 , Figures 5 to 7As shown, the side-mounted mapping unit 302 includes: a mapping machine housing 3021, a laser guide tube 3022, a shock-absorbing rubber pad 3023, a mapping algorithm chip 3025, a first receiver mounting bracket 3026, a light sensor 3027, and a third receiver 3028; the lower end of the mapping machine housing 3021 is provided with a shock-absorbing rubber pad 3023, and the lower end of the shock-absorbing rubber pad 3023 is mounted on the upper surface of the linear guide car 301; the upper end of the mapping machine housing 3021 is fixedly mounted with a laser guide tube 3022, which is used to protect against external light interference factors and improve laser quality.

[0035] A light sensor 3027 is fixedly installed inside the surveying machine housing 3021. A third receiver 3028 is located inside the housing 3021 and on either side of the light sensor 3027. A surveying algorithm chip 3025 is located at the rear end of the third receiver 3028, and a first receiver mounting bracket 3026 is located at the rear end of the third receiver 3028. To achieve more accurate surveying, a separate surveying algorithm chip 3025 is used to process the data, and the processed data is then transmitted to the integrated control box 309 via a wiring harness. The calculation program loaded in the surveying algorithm chip 3025 has the same calculation logic as described above.

[0036] It should be noted that an adjustment component bracket 3024 is provided at the lower end of the inner casing 3021 of the surveying machine to stably support the laser calibration component 303. A high-speed silent motor is fixedly installed on the side of the laser calibration component 303. The high-speed silent motor is a 42BL50S30 series model.

[0037] In the above technical solution, a laser is emitted from the first laser generator 306 at the upper end of the side mapping unit 302, passes through the laser guide tube 3022 and enters the laser calibration component 303. The laser calibration component 303 adjusts and converts the single-point beam into light to sweep across the area. During the sweep, the light sensor 3027 detects the light and records the emission time. When the laser is reflected and received by the third receiver 3028, the interval time is calculated. The interval time is the time difference detected by the third receiver 3028 and the light sensor 3027, and is simultaneously recorded by the mapping algorithm chip 3025. In order to distinguish the swept laser, the frequency of the optical fiber is changed cyclically during each laser emission and each emission period to ensure that the thickness and top-view dimensions of the aluminum material are measured.

[0038] It should be noted that, in order to distinguish the sweeping lasers, the laser frequency per second is between 8000Hz and 9000Hz, alternating in a cycle at 100Hz intervals.

[0039] like Figure 1 , Figure 3 , Figures 8 to 10As shown, the laser calibration component 303 includes: a calibration component housing 3031, a motor shaft 3032, a reflecting prism frame 3033, and a reflecting prism 3034. The calibration component housing 3031 is fixedly mounted on an adjustment component bracket 3024, and the adjustment component bracket 3024 is integrally connected to the upper laser guide tube 3022. The motor shaft 3032 is rotatably mounted inside the calibration component housing 3031. The reflecting prism frame 3033 is fixedly mounted on the side of the motor shaft 3032, and the reflecting prism 3034 is fixedly mounted on the outer end of the reflecting prism frame 3033. The reflecting prism frame 3033 and the reflecting prism 3034 are dynamically balanced by high-speed rotation to reduce the shaking generated during rotation.

[0040] It should be noted that the adjustment component housing 3031 has several matte velvet plates 3035 inside, and a matte velvet hopper 3037 is provided on one side of the matte velvet plate 3035. The matte velvet hopper 3037 is provided on both the upper and lower sides of the matte velvet hopper 3037 and the matte hopper bracket 3036 is connected to the inner wall of the adjustment component housing 3031.

[0041] The matte velvet hopper 3037 has a parallel light lens 3038 fixedly installed in the middle. A laser light guide groove 3039 is located on the back of the adjustment component housing 3031 and the photosensitive sensor 3027 to improve the quality of the adjusted beam. Both the matte velvet plate 3035 and the matte velvet hopper 3037 are made of flocked light-absorbing fabric and layered with flame-retardant fabric to improve safety. The parallel light lens 3038 is manufactured with a special curvature.

[0042] In this embodiment, the laser emitted by the first laser generator 306 enters the calibration component housing 3031 through the laser guide tube 3022, and then the high-speed silent motor installed on one side of the calibration component housing 3031 is started, so that the motor shaft 3032 inside the calibration component housing 3031 can rotate, and the reflective prism 3034 installed on it can rotate synchronously, so that the reflection angle of the laser emitted from above can be continuously changed. The reflected laser light is continuously swept across a parallel light lens 3038 on one side. The refractive index of the processed parallel light lens 3038 converts all the swept laser light into parallel light, refracting the reflected laser light into parallel light, which is then emitted from the laser guide groove 3039. The frequency of the laser sweep depends on the rotation speed of the high-speed silent motor. Using this method, laser measurement can ensure that data can be plotted on the sides of aluminum materials of different thicknesses within the measurement range.

[0043] Among them, such as Figure 10 As shown in the figure, the two rotating reflective prisms 3034 reflect the laser light onto the parallel light lens 3038, resulting in the laser light being refracted into a parallel laser light.

[0044] Working principle: This invention uses a gantry surveying component 3 slidably mounted on an integrated guide rail 2 to transport uncut aluminum material from an electric transport roller 5 to a horizontal grid plate 6 for stable placement. The gantry surveying component 3 then moves along the integrated guide rail 2 to survey the aluminum material. A refraction-based transceiver method is used to increase the laser path and reduce time monitoring errors. After completion, the lifting cylinder 7 is activated, lifting the lifting conveyor belt 8 to lift the aluminum material for unloading, followed by processing. The integrated guide rail 2 is sealed with a dust-proof sealing ring on the side of the linear guide rail 301 to prevent dust from entering the linear guide rail 301 during movement, thus reducing the impact of vibration on laser measurement. The gantry moving car 308 then slides on the gantry guide rail 307, where a second laser generator 311 emits a laser beam at an angle. The beam is reflected off the aluminum material at the lower end and received by the corresponding second receiver 312. The reflection angle and time difference data are then transmitted via the wiring harness at the upper end of the second laser generator 311 to the integrated control box 309 for calculation, yielding the thickness data of the aluminum material measured from directly above. The laser beam is emitted from the first laser generator 306 at the top of the side-view mapping unit 302, passes through the laser guide tube 3022 and enters the laser calibration component 303. The laser calibration component 303 adjusts and converts the single-point beam into light that sweeps across the area. During the sweep, the light sensor 3027 detects the light and records the emission time. When the laser is reflected and received by the third receiver 3028, the interval time is calculated. To distinguish the swept laser beams, the frequency of the optical fiber is cyclically changed during each emission period, ensuring that the thickness and top-view dimensions of the aluminum material are measured. The laser emitted by the first laser generator 306 enters the calibration component housing 3031 through the laser guide tube 3022. Then, the high-speed silent motor installed on one side of the calibration component housing 3031 is started, which enables the motor shaft 3032 inside the calibration component housing 3031 to rotate, and the reflective prism 3034 installed on it to rotate synchronously, thereby continuously changing the reflection angle of the laser emitted from above. The reflected laser light is continuously swept across a parallel light lens 3038 on one side. The refractive index of the processed parallel light lens 3038 converts all the swept laser light into parallel light, refracting the reflected laser light into parallel light, which is then emitted from the laser guide groove 3039. The frequency of the laser sweep depends on the rotation speed of the high-speed silent motor. Using this method, laser measurement can ensure that data can be plotted on the sides of aluminum materials of different thicknesses within the measurement range.

For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. All obvious variations or modifications derived from the technical solutions of the present invention are still within the protection scope of the present invention.
