Description

Technical Field

[0001] The invention relates to the technical field of laser cleaning equipment, and more specifically, to a handheld multifunctional laser double-swing cleaning head. Background Art

[0002] Laser cleaning technology is becoming more and more common in industrial applications. Laser cleaning is also called laser ablation. It mainly uses pulsed laser to remove the material (dirt) on the surface of the cleaning part. The material (dirt) on the surface of the cleaning part evaporates or sublimates after being heated by the absorbed laser energy, thereby achieving the cleaning effect.

[0003] At present, the most common laser cleaning equipment on the market is the laser cleaning machine, and the laser cleaning machine is divided into two types: body type and handheld type. The handheld cleaning equipment can adjust the cleaning position at will, and can achieve the effect of efficient descaling for small and medium-sized cleaning parts. The handheld cleaning equipment can be divided into two types in terms of function: single pendulum type and double pendulum type. The two methods are just based on the two forms of laser projection on the laser cleaning head. The single pendulum structure projects the laser beam onto the cleaning part through a set of galvanometer elements. Under the action of the swinging frequency, the projected part will present a linear state. As the cleaning head moves, the material (dirt) on the surface of the cleaning part is cleaned. Compared with the single pendulum structure, the double pendulum structure has an additional set of galvanometer elements. Through the mutual cooperation of the two sets of galvanometer elements, the projection angle of the laser beam is further changed, thereby achieving the purpose of increasing the cleaning range of the surface of the cleaning part.

[0004] The double-pendulum structure mainly achieves the purpose of cleaning through two sets of matching galvanometer elements. To be more precise, the trajectory of the laser beam is adjusted through the galvanometer on the galvanometer element. For the galvanometer elements in the handheld double-pendulum cleaning heads currently on the market, the galvanometers thereon are all fixed with screws to the seat at the drive end of the motor. Both sets of galvanometer elements belong to a single galvanometer structure. Due to factors such as the size and structure of the galvanometer, the two sets of galvanometer elements cooperate with each other, which causes certain limitations on the overall projection range of the laser beam. When facing some slightly larger cleaning parts, although the cleaning efficiency is higher than that of the single-pendulum structure, it cannot shorten the overall cleaning process of such cleaning parts. At the same time, the galvanometer that is affected by the laser beam for a long time will also age. Due to the limitations of the conventional fixing form, the replacement efficiency of the galvanometer will also be affected.

[0005] Therefore, in order to solve the above technical problems, the present application proposes a handheld multifunctional laser double-swing cleaning head. Summary of the invention

[0040] like Figure 1-12 As shown, the present invention provides a handheld multifunctional laser double-swing cleaning head, comprising a device box 1 and a grip rod 2 arranged at the bottom of the device box 1;

[0041] The projection end of the device box 1 is provided with a projection port 107 for laser projection. Two groups of radially arranged swing components for adjusting laser projection are installed inside the device box 1. A laser emission end is arranged on the top side of the device box 1. The two groups of swing components are swing components a3 and swing components b4. The swing components a3 and b4 have the same structure, both consisting of a disc-shaped seat 5, a galvanometer component 6, an adjustment component 7 and a motor 8. A fixing seat 108 for mounting the swing component a3 is arranged on the bottom surface of the device box 1. The swing component b4 is installed on one side of the inner wall of the device box 1.

[0042] Further explained, the projection port 107 is opened with the largest projection lens 601 in the multiple groups of galvanometer mirror assemblies 6 as a reference basis. The opened projection port 107 needs to ensure that the port will not affect the mutual projection between the lenses 601 during the swinging of the two groups of swing assemblies. At the same time, a corresponding protective mirror body needs to be installed on the projection port 107;

[0043] The two sets of disc-shaped seats 5 are both adjusted in position and angle by a lifting seat 506 with damping at the mounting end and a rotating seat 505 arranged on the telescopic end of the lifting seat 506. Adjusting members for engaging and driving the lateral angle adjustment of the two sets of disc-shaped seats 5 are respectively arranged on the outer walls on both sides of the equipment box 1. The disc-shaped seat 5 is composed of an inner ring 501 and an outer ring 502. An installation gap is arranged between the inner ring 501 and the outer ring 502. A connecting seat 503 with an integrated structure and used to connect the rotating seat 505 and the connecting rod 702 is arranged on the inner side of the inner ring 501. A mounting seat 504 with a circular distribution and used to install the galvanometer assembly 6 is arranged in the mounting gap. A transmission tooth 507 is arranged on the outer wall of the outer ring 502.

[0044] Specifically, the two sets of disc-shaped seats 5 are mainly used to install multiple sets of galvanometer mirror assemblies 6. At the same time, through the linear position adjustment and rotation of the disc-shaped seat 5, the galvanometer mirror assemblies 6 on the disc-shaped seat 5 are respectively connected to the corresponding motor 8 for transmission, and the positions of the multiple sets of galvanometer mirror assemblies 6 on the disc-shaped seat 5 can be exchanged according to actual needs. The lifting seat 506 with damping is used to avoid the disc-shaped seat 5 from being unable to limit itself after extension due to its own gravity, which affects the rotation of the disc-shaped seat 5.

[0045] In order to adapt the galvanometer assembly 6 to different cleaning needs and quickly replace the aged galvanometer assembly 6, as shown in FIG. Figure 5 , Figure 6 and Figure 7 As shown, the galvanometer assembly 6 is provided with multiple groups, and is arranged on the disc-shaped seat 5 according to the circumference. The multiple groups of galvanometer assemblies 6 and the disc-shaped seat 5 are in an independent rotation structure. The galvanometer assembly 6 of the independent rotation structure is not affected by the rotation of the disc-shaped seat 5 on the one hand, and can realize independent connection with the motor 8 on the other hand;

[0046] In order to achieve the exchange between multiple groups of galvanometer components 6 and connect the exchanged galvanometer components 6 with the motor 8, two issues need to be considered in the whole process. First, when the multiple groups of galvanometer components 6 rotate through the disc-shaped seat 5, it is necessary to separate the motor 8 from the galvanometer components 6. Second, after one of the multiple groups of galvanometer components 6 is connected to the motor 8, during the process of the motor 8 transmitting the transmission to it, it is necessary to ensure that the disc-shaped seat 5 is in a stable state. Therefore, it is necessary to achieve the above effect by adjusting the component 7, such as Figure 5 , Figure 6 , Figure 7 and Fig.12As shown, the adjustment component 7 is arranged on the top side of the outside of the device box 1 and on the outer box body beside the projection port 107. Since the two sets of swing components are arranged at different positions, the corresponding adjustment components 7 also need to be arranged in a position corresponding to them. The two sets of adjustment components 7 penetrate the device box 1 through the connecting rod 702 arranged at the bottom and are respectively connected to the central part of the two sets of disc-shaped seats 5. Fixing members for limiting the adjustment components 7 are arranged on both sides of the adjustment components 7;

[0047] Specifically, the adjustment component 7 can manually adjust the disc-shaped seat 5 linearly from the outside of the device box 1, and the linear position of the disc-shaped seat 5 is changed to realize the connection and separation of the galvanometer assembly 6 and the transmission end of the motor 8. At the same time, after the adjustment component 7 drives the disc-shaped seat 5 to connect the galvanometer assembly 6 with the motor 8, it is also necessary to fix it with a fixing member to ensure the overall stability of the disc-shaped seat 5, and will not affect the swing of the galvanometer assembly 6 driven by the motor 8;

[0048] Correspondingly, according to the positions of the two groups of swing components, the motor 8 will be respectively arranged on the fixed seat 108 and on one side inner wall of the device box 1 so that it corresponds to the positions of the two groups of swing components. The two groups of motors 8 are both in the projection area of ​​the projection port 107 and correspond to the positions of the galvanometer components 6 arranged on the two groups of disc-shaped seats 5. A limiting piece for limiting and engaging with the galvanometer components 6 is arranged on the transmission end of the motor 8. The galvanometer components 6 connected to the motor 8 on the swing component b4 correspond to the positions of the laser emission end. The motor 8 will be connected to the corresponding galvanometer components 6 through the limiting piece to achieve the transmission effect. At the same time, the laser projected by the laser emission end will be preferentially reflected by the swing component b4, and the swing component b4 will also reflect the laser to the swing component a3, so that the cooperation of the two mirrors can achieve the laser projection effect.

[0049] In order to facilitate manual adjustment of the rotation of the upper disc seat 5 of the two sets of swing assemblies from the outside of the device box 1, the position exchange between different galvanometer assemblies 6 can be realized, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is necessary to realize it through two sets of adjusting members corresponding to the swing assembly a3 and the swing assembly b4, and the two sets of adjusting members are adjusting members a and adjusting members b which are arranged radially;

[0050] The above-mentioned adjustment member a is arranged on the outer wall of the device box 1 on one side of the swing assembly a3, and includes an adjustment seat a101 and a toothed disc a102. The toothed disc a102 is rotatably connected to a slot hole arranged on the adjustment seat a101 and communicating with the inside and outside of the device box 1. The toothed disc a102 is meshedly connected with the transmission teeth 507 arranged on the outer ring 502 of the swing assembly a3.

[0051] Meanwhile, the adjusting member b is arranged on the outer wall of the device box 1 on one side of the swinging assembly b4, and comprises an adjusting seat b104 and a toothed disc b105. The toothed disc b105 is rotatably connected to a slot hole arranged on the adjusting seat b104 and communicating with the inside and outside of the device box 1. The toothed disc b105 is meshedly connected with the transmission teeth 507 arranged on the outer ring 502 of the swinging assembly b4.

[0052] Specifically, the two groups of adjustment members have the same structure, and the setting method is determined according to the positions of the two groups of swing assemblies. The adjustment members mainly mesh the transmission teeth 507 on the outer ring 502 of the disc-shaped seat 5 on the two groups of swing assemblies through the toothed disc, and the rotation of the disc-shaped seat 5 is adjusted by turning the toothed disc. This method is convenient for manual operation, and the rotation angle of the disc-shaped seat 5 can be quickly adjusted to realize the position exchange of different galvanometer assemblies 6;

[0053] In order to achieve the best cleaning effect for different cleaning parts, such as Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, it is necessary to set up multiple groups of galvanometer mirror assemblies 6 for targeted replacement, which specifically include the following: multiple groups of galvanometer mirror assemblies 6 are composed of lenses 601, limit seats a602 and limit blocks 603, the limit seats a602 are rotatably connected in the mounting seat 504, the lenses 601 and the limit blocks 603 are respectively arranged at the top and bottom of the limit seats a602, the lenses 601 of the multiple groups of galvanometer mirror assemblies 6 are different, the number of galvanometer mirror assemblies 6 on the swing assembly a3 and the number of galvanometer mirror assemblies 6 on the swing assembly b4 are the same, and the proportions are corresponding, and the laser projection range can be adaptively adjusted by the mutual cooperation of the galvanometer mirror assemblies 6 on the swing assembly a3 and the corresponding galvanometer mirror assemblies 6 on the swing assembly b4;

[0054] Furthermore, the mounting structures and structures of the multiple groups of galvanometer mirror assemblies 6 are the same, and the difference lies in the lenses 601 arranged on the multiple groups of galvanometer mirror assemblies 6. The lenses 601 of different sizes or types have different reflection effects on the laser, which affects the projection of the laser on the cleaning part. At the same time, in order to achieve the best projection effect of the double pendulum, the lenses 601 of the multiple groups of galvanometer mirror assemblies 6 arranged on the two groups of swing assemblies need to be adapted in size, dimension, shape and other factors;

[0055] It should be noted that in order to achieve the best double pendulum effect, in addition to setting multiple groups of galvanometer assemblies 6, it is also necessary to limit the swing amplitude of the motor 8, so that the galvanometer assemblies 6 of different lenses 601 are adapted to different swing amplitudes;

[0056] At the same time, if Figure 5 , Figure 7 and Fig.10As shown, a support rod is further provided between the lens 601 and the limiting seat a602, and the length of the support rod is greater than the thickness of the toothed disc on the adjusting member. In this way, a gap for accommodating the toothed disc on the adjusting member is formed between the lens 601 and the disc-shaped seat 5. When the adjusting assembly 7 drives the disc-shaped seat 5 to connect the galvanometer assembly 6 with the motor 8, the toothed disc itself will not affect the lens 601.

[0057] In order to achieve the effect of replacing the galvanometer assembly 6, each of the multiple groups of galvanometer assemblies 6 includes at least two galvanometer assemblies 6 with the same lenses 601, through the galvanometer assemblies 6 with the same lenses 601;

[0058] The specific settings for the distribution of the galvanometer assembly 6 include the following:

[0059] For example, the galvanometer components 6 are divided into M groups, including M1, M2, M3, ..., wherein M1, M2, M3, ... are all galvanometer components 6 with different lenses 601, and each group of M1, M2, M3, ... also includes two galvanometer components 6 with the same lens 601. If the galvanometer components 6 are divided into M groups, the total number of galvanometer components 6 is 2M;

[0060] In order to achieve the transmission connection with the galvanometer assembly 6, as Fig.10 and Fig.11 As shown, the limiting member arranged on the transmission end of the motor 8 is a limiting seat b801, and a limiting groove 802 corresponding to the size and structure of the limiting block 603 is opened on the limiting seat b801. When the adjustment component 7 drives the disc-shaped seat 5 to connect the galvanometer assembly 6 with the motor 8, the limiting block 603 will be engaged with the limiting groove 802 on the limiting seat b801. In order to ensure the accuracy of the engagement, since the multiple groups of galvanometer assemblies 6 rotate independently, a return spring can also be arranged between the mounting seat 504 and the limiting seat a602. The elasticity of this spring is not too large, and it is best not to affect the swing of the galvanometer assembly 6 by the motor 8.

[0061] like Fig.12 As shown, the adjustment component 7 for linearly adjusting the disc-shaped seat 5 comprises a knob 701, a connecting rod 702 arranged at the bottom of the knob 701 and penetrating the device box 1, a circular piece 703 arranged at the side end of the knob 701, and a fixing buckle 704 penetrating the circular piece 703 and locking with the device box 1, wherein the circular piece 703 is an integral structure with the knob 701 and a through hole is arranged at the center; the fixing buckle 704 comprises a disc body, a strip piece vertically arranged at the top of the disc body, and a threaded end arranged at the bottom of the disc body;

[0062] Specifically, the adjustment component 7 mainly realizes the linear adjustment of the disc-shaped seat 5. At the same time, since the knob 701 is connected to the center point of the disc-shaped seat 5 through the connecting rod 702, the adjustment component 7 can also adjust the rotation of the disc-shaped seat 5. Therefore, the adjustment component 7 can also be used as the second adjustment part of the disc-shaped seat 5. Compared with the toothed disc adjustment, the knob 701 is mainly for the purpose of linear adjustment, with a smaller volume and relatively unchanged manual rotation. The toothed disc is larger and more convenient to adjust. When the toothed disc is damaged or severely worn, it cannot be engaged for transmission, and the adjustment component 7 can be used to adjust the rotation of the disc-shaped seat 5.

[0063] At the same time, at least one circular piece 703 is provided to facilitate manual operation of the knob 701 and to fix the knob 701 in cooperation with the fixing buckle 704. The fixing buckle 704 with a strip piece is in a straight line shape, which improves the convenience of manual disassembly and assembly.

[0064] In order to achieve the accuracy of adjusting the position of each galvanometer assembly 6, as Figure 2 and Figure 3 As shown, the outer wall of the box body at the edge of the two groups of adjustment components 7 is respectively provided with fixing holes a103 and fixing holes b106 for locking the fixing buckle 704 connected to the swing component a3 and the fixing buckle 704 connected to the swing component b4, and there are multiple groups of fixing holes a103 and fixing holes b106;

[0065] Among them, the number of the plurality of fixing holes a103 and the galvanometer components 6 on the swing component a3 are the same, and the positions are corresponding, and the number of the plurality of fixing holes b106 and the galvanometer components 6 on the swing component b4 are the same, and the positions are corresponding;

[0066] Specifically, multiple groups of fixing holes a103 and multiple groups of fixing holes b106 correspond to the positions of multiple galvanometer assemblies 6 on the two groups of swing assemblies respectively. When the fixing buckle 704 can be locked with the corresponding hole body, the accuracy of the adjustment position of the galvanometer assembly 6 can be determined. In application, the corresponding lens 601 mark can be pasted on the bottom of each galvanometer assembly 6, and the adjustment status can be observed through the projection port 107. In addition, the position of the galvanometer assembly 6 can be replaced by cooperating with the adjustment of the adjustment assembly 7.

[0067] In summary, the laser cleaning head adopts two sets of adjustable swing components to cooperate with each other, which can adjust the laser projection to different ranges for different cleaning parts to achieve the best cleaning efficiency. At the same time, the two sets of adjustable swing components can also be used to replace the galvanometer component 6 due to the aging of the lens 601 during long-term use. The adjustment of the laser projection and the replacement of the galvanometer component 6 are specifically as follows:

[0068] The laser projection adjustment process includes the following steps: respectively releasing the locking of the adjustment components 7 corresponding to the swing components a3 and the swing components b4, and directly releasing the locking by hand by using the strip piece on the fixing buckle 704; after releasing the locking, linearly stretching the knob 701 of the adjustment component 7, and the lifting seat 506 will stretch the disc-shaped seat 5 to the maximum telescopic position of the lifting seat 506 under the action of damping, and observe the positions of the corresponding galvanometer components 6 on the disc-shaped seats 5 of the two sets of swing components through the projection port 107, and respectively contact the toothed discs of the corresponding adjustment parts of the two sets of swing components by hand, and realize the adjustment of multiple sets of galvanometer components 6 on the disc-shaped seats 5 of the two sets of swing components by toggling the toothed discs. The position of the galvanometer assembly 6 is adjusted. After adjusting to a suitable position, the fixing buckle 704 is passed through the circular sheet 703 to match the corresponding fixing hole. After the fixing buckle 704 corresponds to the position of the corresponding fixing hole, the accuracy of the position adjustment of the galvanometer assembly 6 can be determined. The linear adjustment knob 701 is used to reset it. The limit block 603 corresponding to the galvanometer assembly 6 on the disc-shaped seat 5 will be engaged with the limit groove 802 of the upper limit seat b801 of the corresponding motor 8. Finally, the fixing buckle 704 is manually locked in the corresponding fixing hole on the equipment box 1. When enabled, the control part of the motor 8 adjusts the swing amplitude of the motor 8 to the swing amplitude adapted to the corresponding lens 601.

[0069] The replacement of the galvanometer assembly 6 is the same as the process of laser projection adjustment, the difference being that the two sets of oscillating assemblies can be adjusted separately without the need for matching adjustment.
