Description

Technical Field

[0001] The invention relates to the technical field of laser radar outer cover coating processing, in particular to a coating machine for a laser radar outer cover. Background Art

[0002] As a core technology in the fields of autonomous driving and environmental perception, the coating quality of the lidar directly affects the detection accuracy, stability and service life of the lidar. Therefore, the development of efficient and precise coating technology has become an important part of the lidar manufacturing process. For example, in some types of evaporative coating, the coating material is heated to a sublimation state, formed into a gaseous state and guided to the substrate through a nozzle, and finally condensed into a thin film on the substrate. This coating method has the advantages of high utilization rate of coating materials, fast deposition rate and good uniformity of film layer. In the application of lidar cover coating machine, the nozzle coating method can achieve fast and uniform coating of the lidar cover, and improve the coating efficiency and quality. In addition, the nozzle coating method can also be customized and optimized according to the specific needs and material properties of the lidar cover. For example, by adjusting the position and number of nozzles, the coating area and thickness can be precisely controlled. At the same time, different coating materials and process parameters can also be selected to meet the requirements of the lidar cover for optical properties, mechanical properties and corrosion resistance.

[0003] During use, the existing laser radar cover coating machine needs to adjust the distance between the nozzle and the cover, increase or decrease the number of nozzles, and adjust the position of the nozzle accordingly when coating laser radar covers of different sizes. Otherwise, it will affect the uniformity and quality of the coating, thereby affecting the performance of the laser radar cover, and it is inconvenient to use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0033] See also Figure 1-Figure 14 The embodiment of the present invention provides a coating machine for a laser radar cover, comprising a coating adjustment seat 1, and further comprising: A covering distribution bracket 2, wherein the covering distribution bracket 2 is fixedly mounted on the coating adjustment seat 1, and a plurality of U-shaped supports 4 are also provided on the covering distribution bracket 2; The covering distribution bracket 2 is also provided with a main coating device, and a plurality of U-shaped supports 4 are circumferentially distributed on the covering distribution bracket 2 around the main coating device; and an automatic film-depositing coating mechanism, which is connected to the U-shaped support 4 and to the main coating device, wherein the automatic film-depositing coating mechanism includes a pre-tightening delivery component and an auxiliary coating device; The auxiliary coating equipment is connected to the U-shaped support 4 and to the main coating equipment; the pre-tightening delivery component is connected to the auxiliary coating equipment and is used to control the time for the auxiliary coating equipment to automatically deliver the coating operation.

[0034] See also Figure 1-Figure 14 The number of the pre-tightening delivery components is multiple, and the multiple pre-tightening delivery components are distributed at different positions on the covering distribution bracket 2, and work in coordination with the corresponding auxiliary coating equipment; The pre-tightening forces set for the multiple pre-tightening and delivery components are the same or different. When the pre-tightening forces are the same, the multiple pre-tightening and delivery components will control the multiple auxiliary coating equipment to be delivered simultaneously to perform coating operations; when the pre-tightening forces are different, the multiple pre-tightening and delivery components will control the multiple auxiliary coating equipment to be delivered in steps to perform coating operations.

[0035] The main coating equipment comprises: A transmission channel 3, wherein the transmission channel 3 is fixedly installed in the middle of the covering distribution bracket 2; A branch pipe 9, wherein the number of the branch pipes 9 is multiple, and the multiple branch pipes 9 are evenly installed on the transmission channel 3 and are all connected to the transmission channel 3, and the multiple branch pipes 9 are respectively connected to multiple auxiliary coating devices; and a main injection head 5 , wherein the main injection head 5 is fixedly mounted on the transmission channel 3 .

[0036] When coating the laser radar housing, first, fix the laser radar housing to be coated on the opposite side of the main injection head 5 (such as Figure 2 As shown), then, according to the size of the laser radar housing, the coating adjustment seat 1 is driven to move by an external driving device, so as to adjust the distance between the main injection head 5 and the laser radar housing, wherein the coating adjustment seat 1 can adopt an open frame structure, or a cylindrical structure with one end open (the end where the main injection head 5 is located is open), and the external driving device can adopt a telescopic cylinder assembly to push the coating adjustment seat 1 and the entire coating equipment to move horizontally, so as to achieve the purpose of adjusting the distance between the main injection head 5 and the laser radar housing. In the process of the coating adjustment seat 1 driving the covering distribution bracket 2 and the automatic coating delivery mechanism to move, when the displacement of the movement is large, under the control of the pre-tightening delivery assembly, multiple auxiliary coating devices at different positions on the covering distribution bracket 2 will be actuated and consistent with the injection direction of the main injection head 5, wherein the pre-tightening delivery assembly can be connected to an external component, and the pre-tightening force of the pre-tightening delivery assembly can be manually adjusted, so that the pre-tightening forces set by multiple pre-tightening delivery assemblies can be the same or different. When the pre-tightening forces are the same, multiple pre-tightening delivery assemblies It will control multiple auxiliary coating equipment to be released simultaneously for coating operation; when the preload force is different, multiple preload release components will control multiple auxiliary coating equipment to be released step by step for coating operation (the attached figure only shows the setting of four sets of preload release components and auxiliary coating equipment. The actual number can be increased or decreased according to needs, and no further details will be given here). After the position adjustment of the main injection head 5 and multiple auxiliary coating equipment is completed, the evaporated material will reach the main injection head 5 and the auxiliary coating equipment respectively through the transmission channel 3 and the branch pipe 9, and finally be sprayed outward. Due to the adjustment of the distance between the main injection head 5 and the laser radar housing to be coated, and the increase or decrease in the number of auxiliary coating equipment, the coverage range of the sprayed evaporated material can be changed. Especially for some areas with poor coating conditions, a directional spraying method can be adopted to achieve sufficient and uniform coating operations on laser radar housings of different sizes, and avoid frequent disassembly and assembly of auxiliary coating equipment, which is beneficial to ensure the quality and efficiency of production, and improve the optical and mechanical properties of the laser radar housing, providing convenience for the staff.

[0037] In one embodiment of the present invention, see Figure 1-Figure 14 , the auxiliary coating equipment comprises: A protective shell 6, wherein the protective shell 6 is fixedly connected to the U-shaped support 4, and an arc-shaped adjustment groove 7 is formed on the protective shell 6, and an angle corresponding to the arc-shaped adjustment groove 7 is greater than 180°; An adjusting support plate 10, wherein the adjusting support plate 10 passes through the arc-shaped adjusting groove 7 and is slidably connected to the arc-shaped adjusting groove 7, and an auxiliary injection head 17 and a joint 18 are also installed on the adjusting support plate 10, and the joint 18 is connected to the main coating device; And a rotating shaft 23, the rotating shaft 23 is rotatably installed in the protective shell 6 and is fixedly connected to the adjusting support plate 10, and the rotating shaft 23 is also connected to the pre-tightening delivery assembly.

[0038] By setting up multiple protective shells 6, the number and position of the protective shells 6 can be selected according to actual needs, and the pre-tightening force of the pre-tightening delivery component corresponding to each protective shell 6 can be adjusted to meet the coating requirements of laser radar covers of different sizes. As the distance between the main injection head 5 and the laser radar cover to be coated is adjusted, when the displacement of each protective shell 6 is the same, if the pre-tightening force of the pre-tightening delivery component corresponding to each protective shell 6 is different, the corresponding adjustment support plate 10 will be moved in sequence. For example, when the distance between the main injection head 5 and the laser radar cover is larger, it means that the size of the laser radar cover to be coated is larger and needs to cover a larger spraying range. At the same time, under the control of the pre-tightening delivery component, multiple auxiliary injection heads 17 at multiple positions will be synchronously delivered to work to ensure the quality and effect of the coating. When the adjustment support plate 10 rotates 180° in the arc-shaped adjustment groove 7, the auxiliary injection head 17 will have the same spraying direction as the main injection head 5, thereby completing the adjustment of the position and quantity of the main injection head 5 and the auxiliary coating equipment.

[0039] In one embodiment of the present invention, see Figure 1-Figure 14 , the preload delivery component comprises: A rotation control channel 22, wherein the rotation control channel 22 is fixedly connected to the inner wall of the protective shell 6; An arc-shaped guide magnetic plate 28, wherein the arc-shaped guide magnetic plate 28 is slidably mounted in the rotation control channel 22, and one end of the arc-shaped guide magnetic plate 28 is fixedly connected to the inner wall of the rotation control channel 22 via a reset elastic band 25; A thin pull rope 12, one end of which passes through the rotation control channel 22 and is slidably connected to the rotation control channel 22, and the thin pull rope 12 is also fixedly connected to the other end of the arc-shaped guide magnetic plate 28; A buffer spring 13, one end of which is fixedly connected to the other end of the thin pull rope 12, and a thick pull rope 15 is fixedly installed on the other end of the buffer spring 13; And a rotation control unit, which is respectively connected to the protective shell 6, the buffer spring 13, the rotation control channel 22 and the rotation shaft 23.

[0040] The rotation control unit comprises: A rotating circular plate 21, wherein the rotating circular plate 21 is fixedly mounted on the rotating shaft 23, and the rotating circular plate 21 is also slidably connected to the rotating control channel 22; A linkage baffle 27, wherein the linkage baffle 27 is fixedly connected to the rotating circular plate 21, and the linkage baffle 27 is also located in the rotation control channel 22; And a driving detection module, wherein the driving detection module is connected to the protective shell 6, the buffer spring 13 and the rotating shaft 23 respectively.

[0041] The drive detection module comprises: A telescopic state detector 14, wherein the telescopic state detector 14 is fixedly mounted on the buffer spring 13; A rotating driving member 24, wherein the rotating driving member 24 is fixedly connected to the inner wall of the protective housing 6 and is electrically connected to the telescopic state detector 14, and a sliding tooth plate 31 is also installed on the rotating driving member 24; and a driven gear 20 , wherein the driven gear 20 is fixedly mounted on the rotating shaft 23 and meshedly connected with the sliding tooth plate 31 .

[0042] The rotation control unit also includes: A smooth pushing portion 29, wherein the smooth pushing portion 29 is located on the arc-shaped guide magnetic plate 28; And a magnetic telescopic positioning plate 30 , which is fixedly mounted on the rotating shaft 23 , and the magnetic telescopic positioning plate 30 also passes through the through opening opened on the rotating control channel 22 and abuts against the smooth pushing portion 29 .

[0043] See also Figure 1-Figure 14 , further comprising: a smooth wire opening 26, the smooth wire opening 26 being located on the rotation control channel 22 and being slidably connected to the thin pull rope 12; And a wire barrel 16, which is fixedly mounted on the protective shell 6 and communicated with the protective shell 6, wherein the thin pull rope 12 passes through the wire barrel 16 and is slidably connected with the wire barrel 16.

[0044] like Fig.14 As shown, at this time, the pre-tightening delivery assembly and the auxiliary injection head 17 are in a retracted state. As the distance between the main injection head 5 and the laser radar housing is adjusted, when the distance between the two gradually increases, one or more thick pull ropes 15 gradually become relaxed. At this time, under the pulling action of the reset elastic band 25, the arc-shaped guide magnetic plate 28 will rotate clockwise in the rotation control channel 22 (as shown in FIG. Fig.14As shown), at this time, the rotating shaft 23, the linkage baffle 27 and the rotating circular plate 21 are in a stationary state under the limiting action of the magnetic telescopic positioning plate 30. At this stage, the elongation of the buffer spring 13 remains approximately unchanged, and the telescopic state detector 14 is in a non-working state. As the distance between the main injection head 5 and the laser radar housing gradually increases, when the smooth pushing portion 29 completely leaves the magnetic telescopic positioning plate 30, the smooth pushing portion 29 can adopt an inclined smooth surface structure, so that the magnetic telescopic positioning plate 30 gradually shrinks into the rotating shaft 23 during the rotation of the arc-shaped guide magnetic plate 28. When the magnetic telescopic positioning plate 30 reaches the inner side wall of the arc-shaped guide magnetic plate 28, the magnetic repulsion force of the arc-shaped guide magnetic plate 28 on the magnetic telescopic positioning plate 30 Under this condition, the magnetic telescopic positioning plate 30 can be completely retracted into the rotating shaft 23. At this time, the magnetic telescopic positioning plate 30 is separated from the through-port on the rotating control groove 22, and the limiting effect on the rotating shaft 23 is released. As the main injection head 5 continues to move, the elasticity of the reset elastic belt 25 is greatly weakened, and the buffer spring 13 begins to gradually shrink. The buffer spring 13 can be set to a specified value according to the expansion amount. When the buffer spring 13 shrinks to less than the specified value, the rotating drive member 24 is put into operation. The rotating drive member 24 can be in the form of an electromagnet. The rotating drive member 24 will push the sliding tooth plate 31 to move horizontally under the action of the magnetic repulsion force, and the meshing transmission between the sliding tooth plate 31 and the driven gear 20 makes the sliding tooth plate 31 drives the rotating shaft 23 to rotate clockwise, and makes the adjusting support plate 10 rotate synchronously in the arc-shaped adjusting groove 7, and finally makes the auxiliary injection head 17 rotate to the working position. In this process, the rotating circular plate 21 and the linkage baffle 27 will also rotate synchronously, and make the linkage baffle 27 contact with the end of the arc-shaped guide magnetic plate 28 again. At this time, under the limiting effect of the sliding tooth plate 31 on the driven gear 20, the auxiliary injection head 17 can be firmly put into the coating operation. After the work is completed, in the process of restoring the main injection head 5 to its original position, the buffer spring 13 will be stretched first. When the telescopic state detector 14 detects that the elongation of the buffer spring 13 is greater than the specified value, the rotating drive member 24 will be powered off and set to delay power on. At this time, the arc-shaped guide magnetic plate 28 will be under the tension. Under the action of the thin pull rope 12, the adjustment support plate 10 and the auxiliary injection head 17 are restored to their original positions, and when the magnetic telescopic positioning plate 30 reaches the smooth pushing portion 29, the spring arranged in the rotating shaft 23 will push the magnetic telescopic positioning plate 30 to extend outward, and after passing through the through opening, it will abut against the smooth pushing portion 29, thereby realizing the limiting function of the adjustment support plate 10 and the auxiliary injection head 17 in the non-working state. No further elaboration will be made here.

[0045] In one embodiment of the present invention, see Figure 1-Figure 14 , further comprising: a telescopic control member 8, wherein the telescopic control member 8 is fixedly mounted on the U-shaped support 4 and is electrically connected to the preload delivery assembly; A tensioning connecting rod 19, one end of which is fixedly connected to the output end of the telescopic control member 8, and the other end of which passes through the U-shaped support 4 and is slidably connected to the U-shaped support 4; And an arc-shaped plugging plate 11, wherein the arc-shaped plugging plate 11 is fixedly connected to the other end of the tightening connecting rod 19, and the arc-shaped plugging plate 11 is also detachably connected to the auxiliary coating equipment.

[0046] By setting a specified value for the buffer spring 13 (for example, the middle value of the spring tension is a specified value), when the buffer spring 13 is in a tensioned state, the main injection head 5 is closest to the laser radar housing, and the coverage range of its injection meets the requirements of coating, so there is no need for the participation of auxiliary coating equipment. At this time, under the control of the telescopic state detector 14 on the buffer spring 13, the telescopic control component 8 can be started, and the tightening connecting rod 19 and the arc plug plate 11 can be pushed to move synchronously, so that the auxiliary injection head 17 can be compressed. On the one hand, it can avoid the leakage of evaporation materials and protect the auxiliary injection head 17 during non-working periods. On the other hand, it can play a positioning role to avoid the displacement of multiple auxiliary coating equipment during the coating operation. Movement or shaking, on the contrary, when the distance between the main injection head 5 and the laser radar housing is increased, after moving a certain distance, for example, a certain buffer spring 13 is gradually in a relaxed state, when the pulling force of the buffer spring 13 is less than the specified value (at this time, the pre-tightening delivery component has not yet been put into operation, and the preset value of the pre-tightening delivery component is smaller than the specified value, so that the pre-tightening delivery component can be operated after the telescopic control component 8), the telescopic control component 8 is started, and the tensioning connecting rod 19 and the arc plug plate 11 are pulled away from the auxiliary injection head 17, thereby releasing the limiting effect on the auxiliary injection head 17, so that the subsequent pre-tightening delivery component can drive the auxiliary injection head 17 to change its position state, thereby engaging in the coating work, which will not be elaborated here.

[0047] It should be noted that in the present invention, unless otherwise clearly specified and limited, the terms "slide", "rotate", "fix", "have" and the like should be understood in a broad sense, for example, it can be a welding connection, a bolt connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.
