[0034] The following will disclose multiple embodiments of the present invention with drawings. For the purpose of clear description, many practical details will be described together in the following description. However, it should be understood that these practical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these practical details are not necessary. In addition, for the purpose of simplifying the drawings, some conventional structures and components will be depicted in a simple schematic manner in the drawings.

[0035] It should be noted that all directional indications such as up, down, left, right, front, back, etc. in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0036] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes, and do not specifically refer to the order or sequence, nor are they used to limit the present invention. They are only used to distinguish components or operations described with the same technical terms, and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0037] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings:

[0038] Reference Figure 1 , Figure 1 Schematic diagram of the structure of the laser cleaning device in this embodiment. The laser cleaning device in this embodiment includes an unwinding device 1, a first buffer device 2 and a first cleaning device 3. The first buffer device 2 is adjacent to the unwinding device 1, and the first cleaning device 3 is adjacent to the first buffer device 2. The unwinding device 1 is used to release the strip, the first buffer device 2 receives the released strip and buffers the strip, and the first cleaning device 3 pulls the strip buffered by the first buffer device 2 in a fixed section and cleans the strip.

[0039] The first cleaning device 3 pulls the strip cached in the first cache device 2 in fixed sections, so that the position of the strip to be cleaned can be accurately moved to the cleaning position of the first cleaning device 3, thereby making the cleaning of the first cleaning device 3 accurate and ensuring the cleaning quality.

[0040] Re-reference Figure 1 Furthermore, the laser cleaning device in this embodiment further includes a first deflection correction device 4. The first deflection correction device 4 is located between the first buffer device 2 and the first cleaning device 3. The strip pulled by the first cleaning device 3 passes through the first deflection correction device 4, and the first deflection correction device 4 corrects the deflection of the strip. The first deflection correction device 4 corrects the running direction of the strip, ensuring that the running direction of the strip when pulled by the first cleaning device 3 is accurate, thereby further improving the cleaning accuracy and cleaning quality.

[0041] Re-reference Figure 1 Furthermore, the laser cleaning device in this embodiment also includes a first detection device 5. The first detection device 5 is located between the first buffer device 2 and the first cleaning device 3, and is arranged on the correction path of the first correction device 4. The first detection device 5 is used to detect the coating reference position of the strip after correction, and the first cleaning device 3 pulls the strip in sections according to the coating reference position. By detecting the coating reference position of the strip, the first cleaning device 3 uses the coating reference position of the strip as the tape running reference, thereby pulling the strip in sections, ensuring that the tape running length of the tape pulled in sections is accurate, and further improving the cleaning accuracy and cleaning quality.

[0042] Re-reference Figure 1 Furthermore, the laser cleaning device in this embodiment further includes a second buffer device 6. The second buffer device 6 is adjacent to the first cleaning device 3, and the second buffer device 6 receives the cleaned strip and buffers the strip. The second buffer device 6 buffers the cleaned strip to facilitate the processing of other subsequent processes.

[0043] Continue to refer to Figure 2 , Figure 2 1 is a schematic diagram of the structure of the strip in this embodiment. The strip 100 in this embodiment includes a base strip 110, a coating film 120 and a cleaning tank 130. There are multiple coating films 120, and multiple coating films 120 are sequentially coated on the surface of the base strip 110 at intervals. Preferably, the spacing between two adjacent coating films 120 is the same. The beginning of each coating film 120 has a coating reference position 140, and the cleaning tank 130 is a slot cleaned at a set position on the coating film 120 by laser cleaning, so that the base strip 110 is exposed to the coating film 120, which is convenient for subsequent welding requirements. The structure of performing segmented coating on the base strip 110 and forming multiple coating films 120 arranged at intervals can be achieved through the existing coating process, which will not be repeated here. It is worth noting that the spacing between two adjacent coating films 120 in the multiple coating films 120 is determined by the coating process. Preferably, the spacing between two adjacent coating films 120 is the same, but it may also be due to the coating process error that the spacing between two adjacent coating films 120 is different. The cleaning tank 130 to be cleaned in this embodiment is in the shape of a rectangular tank. It is understandable that the strip 100 coated with the coating film 120 will be transported in the form of a coil, and the strip 100 will also be loaded in the form of a coil.

[0044] Re-reference Figure 1Furthermore, the laser cleaning device in this embodiment also includes a frame 200. The unwinding device 1, the first buffer device 2, the first cleaning device 3, the first deviation correction device 4, the first detection device 5 and the second buffer device 6 are respectively arranged on the frame 200. The frame 200 in this embodiment is a frame with a longitudinal section that is approximately rectangular. The unwinding device 1 is arranged at the front end of the frame 200. The unwinding device 1 in this embodiment includes an unwinding mechanism 11, an unwinding direction changing mechanism 12, a tension detection mechanism 13 and an unwinding main drive mechanism 14. The unwinding mechanism 11, the unwinding direction-changing mechanism 12, the tension detection mechanism 13 and the unwinding main drive mechanism 14 are respectively arranged on the frame 200, wherein the unwinding mechanism 11 is arranged at the front end of the frame 200 and close to the bottom of the frame 200, the unwinding direction-changing mechanism 12 is located above the unwinding mechanism 11, the unwinding main drive mechanism 14 is located on the side of the unwinding mechanism 11 away from the front end of the frame 200, and the tension detection mechanism 13 is located between the unwinding direction-changing mechanism 12 and the unwinding main drive mechanism 14. The rolled strip 100 is arranged on the unwinding mechanism 11, and the unwinding mechanism 11 releases the rolled strip 100. The released strip 100 is sequentially wound around the unwinding direction-changing mechanism 12, the tension detection mechanism 13 and the unwinding main drive mechanism 14. The unwinding main drive mechanism 14 is used as an unwinding power source, which pulls the strip 100, so that the rolled strip 100 rotates at the unwinding mechanism 11, thereby releasing the strip 100. The rolled strip 100 is heavy, and the unwinding mechanism 11 is arranged near the bottom and the front end of the frame 200, so that the operator can easily load the rolled strip 100. It is understandable that the released strip 100 cannot be wrinkled or deformed, otherwise it will affect the subsequent cleaning. In order to ensure the open state of the strip 100, it is necessary to make the pulling force on the strip 100 in the released state appropriate and constant, because if the pulling force on the strip 100 is small, wrinkles will appear, and conversely, if the pulling force on the strip 100 is large, deformation will appear. Therefore, in this embodiment, the tension of the strip 100 pulled by the unwinding main drive mechanism 14 is monitored in real time by setting the tension detection mechanism 13, so as to obtain the real-time information of the tension on the strip 100 and adjust the tension on it, so as to keep the tension of the strip 100 constant and appropriate. Specifically, the tension detection mechanism 13 in this embodiment can adopt the cooperation of a moving roller and a pressure sensor, and the strip 100 wound on the moving roller acts on the pressure sensor, and the pressure sensor detects the tension of the strip 100. The unwinding main drive mechanism 14 adopts the cooperation of a private service motor and a moving roller, and the private service motor drives the moving roller to rotate, thereby pulling the strip 100. The private service motor in this embodiment drives the moving wheel to rotate at a constant speed, that is, the unwinding main drive mechanism 14 pulls the strip in a constant speed mode.The unwinding mechanism 11 in this embodiment can be made of a motor, a driving wheel, a synchronous belt, a driven wheel and an expansion shaft, wherein the output shaft of the motor is coaxially connected to the driving wheel, the driving wheel is connected to the driven wheel through a synchronous belt, the driven wheel and the rolled strip 100 are respectively sleeved on both ends of the expansion shaft, and the expansion shaft is rotatably connected to the frame 200. When the unwinding main drive mechanism 14 pulls the strip 100 to unwind, the motor of the unwinding mechanism 11 is in a torque mode rather than a speed mode. As the strip 100 is released, the roll diameter of the strip 100 will change, and the pressure detected by the tension detection mechanism 13 will change accordingly. At this time, the torque of the motor of the unwinding mechanism 11 needs to change accordingly to keep the tension of the strip 100 unchanged. The unwinding direction-changing mechanism 12 in this embodiment can use a direction-changing roller.

[0045] Continue to refer to Figure 1 and Figure 3 , Figure 3Schematic diagram of the structure of the first buffer device, the first cleaning device, the first deviation correction device, the first detection device, the second buffer device and the frame in this embodiment. Furthermore, the first buffer device 2 is adjacent to the unwinding main drive mechanism 14. The first buffer device 2 includes a fixed roller mechanism 21 and a floating roller mechanism 22. The fixed roller mechanism 21 is located above the floating roller mechanism 22, and the floating roller mechanism 22 can move linearly along a direction perpendicular to the frame 200. The fixed roller mechanism 21 in this embodiment includes a plurality of fixed roller members 211, and the plurality of fixed roller members 211 are arranged in sequence along the length direction of the frame 200. Each fixed roller member 211 is rotatably connected to the frame 200. The fixed roller member 211 in this embodiment can be a roller. The number of fixed roller members 211 in this embodiment is five, and the five fixed roller members 211 form three intervals. The floating roller mechanism 22 includes a floating slide rail 221, a floating slide plate 222 and a plurality of floating roller members 223. There are two floating rails 221, which are laid on the frame 200 in a direction perpendicular to the frame 200. The lower surfaces of the floating slide 222 are respectively slidably connected to the two floating rails 221, and the floating slide 222 is perpendicular to the floating rails 221. A plurality of floating rollers 223 are sequentially arranged at intervals along the length direction of the floating slide 222, and each floating roller 223 is rotatably connected to the floating slide 222. The plurality of floating rollers 223 are staggered with the plurality of fixed rollers 211. The floating rollers 223 in this embodiment can be rollers, and the number of the floating rollers 223 is three, and the three floating rollers 223 correspond to the three intervals formed by the five fixed rollers 211. The strip 100 pulled by the unwinding main drive mechanism 14 is sequentially wound around the fixed roller member 211 and the floating roller member 223 at intervals, thereby forming a cache for the strip 100. When multiple floating roller members 223 descend, the strip 100 can be cached, and when multiple floating roller members 223 rise, the cached strip 100 can be released. Preferably, the first cache device 2 also includes an auxiliary floating mechanism 23. The auxiliary floating mechanism 23 is arranged between two floating slide rails 221 and connected to the floating slide plate 222. The auxiliary floating mechanism 23 can be used as a power source to assist in driving the floating slide plate 222 to slide on the floating slide rail 221. The auxiliary floating mechanism 23 in this embodiment can be used in combination with a motor, a screw rod and a nut. In specific applications, the auxiliary floating mechanism 23 can assist in cooperating with the pulling action of the first cleaning device 1 to release the strip 100 cached in the first cache device 2.

[0046] Re-reference Figure 1 and Figure 3, further, the first deflection correction device 4 is arranged on the side of the first buffer device 2 away from the unwinding device 1, and the first deflection correction device 4 receives the strip 100 cached by the first buffer device 2 and corrects the deflection of the strip 100. The first deflection correction device 4 includes a deflection correction carrier 41, a first deflection correction roller 42 and a second deflection correction roller 43. The first deflection correction roller 42 and the second deflection correction roller 43 are respectively arranged at the upper end of the deflection correction carrier 41, and the first deflection correction roller 42 and the second deflection correction roller 43 are arranged side by side, wherein the first deflection correction roller 42 is close to the first buffer device 2. There is a gap between the first deflection correction roller 42 and the second deflection correction roller 43. The strip 100 is sequentially wound around the first deflection correction roller 42 and the second deflection correction roller 43, and then continues to extend toward the first cleaning device 3. The first deflection correction roller 42 and the second deflection correction roller 43 in this embodiment can be existing deflection correction rollers, and both can correct the passing strip 100 to avoid the deviation of the running direction of the strip 100. When the strip 100 in this embodiment is wound around the first deviation-correcting roller 42 and the second deviation-correcting roller 43 of the first deviation-correcting device 4, it is wound from below the first deviation-correcting roller 42 and the second deviation-correcting roller 43 respectively, so that the entire strip 100 remains in a horizontal state.

[0047] Re-reference Figures 1 to 3 Furthermore, the first detection device 5 is arranged on the side of the first buffer device 2 away from the unwinding device 1, and the first detection device 5 is located above the first deflection correction device 4. The detection end of the first detection device 5 faces the strip 100 between the first deflection correction roller 42 and the second deflection correction roller 43, and detects the strip 100 after deflection correction, identifies and obtains the position information of the coating reference position 140 of the strip 100. Figure 2As shown, the specific position on the coating film 120 where the cleaning groove 130 is formed is artificially set. In actual application, the position of the cleaning groove 130 on the coating film 120 is determined according to actual needs or customer needs. In other words, the position where the cleaning groove 130 is formed is preset and known. When the position of the cleaning groove 130 is known, the position of the coating reference position 140 is detected by the first detection device 5, and then the fixed-segment running length "L" can be calculated. The first cleaning device 3 pulls the strip 100 according to the fixed-segment running length "L", that is, starting from the coating reference position 140, the strip 100 is pulled to move a fixed length of "L" distance, so that the position to be cleaned on the coating film 120 is just opposite to the cleaning position of the first cleaning device 3, so that the first cleaning device 3 can accurately perform laser cleaning at this position, and the cleaning groove 130 formed is accurately positioned and of high quality. Moreover, each time the strip 100 is moved, the re-measured coating reference position 140 is used as the calculation starting point, and after moving a fixed length "L", it reaches the preset cleaning position, which also ensures the position consistency of the cleaning tank 130 formed each time, and can avoid the influence of different spacings between two adjacent coating films 120. The first detection device 5 in this embodiment can use a photoelectric sensor to detect the coating reference position 140. It can be understood that the coating film 120 is coated on the base band 110, and there is a boundary between the base band 110 and the coating film 120. The base band 110 and the coating film 120 have different colors. When the coating film 120 is coated on the starting position of the base band 110, the base band 110 and the coating film 120 will form a boundary line, which is the coating reference position 140 in this embodiment. The base band 110 and the coating film 120 have different colors, and different photoelectric reactions will be generated during detection by the photoelectric sensor. In this way, the coating reference position 140 of the passing strip 100 can be detected by the photoelectric sensor, and then the coating reference position 140 is obtained, that is, the starting position of each coating film 120 on the base band 110 is obtained.

[0048] Continue to refer to Figures 1 to 4 , Figure 4Schematic diagram of the structure of the first cleaning device in this embodiment. Furthermore, the first cleaning device 3 is located on the side of the first correcting device 4 away from the first cache device 2. The first cleaning device 3 includes a cleaning platform 31, a cleaning mechanism 32, a dust removal mechanism 33 and a cleaning main drive mechanism 34. The cleaning platform 31 is located on the side of the first correcting device 4 away from the first cache device 2, the cleaning mechanism 32 is located above the cleaning platform 31, and its cleaning end is facing the cleaning platform 31, the dust removal mechanism 33 is located on the side of the cleaning platform 31, and its dust removal end faces the cleaning platform 31, and the cleaning main drive mechanism 34 is located on the side of the cleaning platform 31 away from the first correcting device 4. The strip 100 that has been inspected by the deviation correction and coating reference position 140 first passes through the surface of the cleaning platform 31, and then continues to extend and is wound around the cleaning main drive mechanism 34. The cleaning main drive mechanism 34 in this embodiment serves as a power source, and its fixed section "L" length pulls the strip 100 that has been inspected by the first detection device 5, so that the position to be cleaned of the coating film 120 of the strip 100 moves to the cleaning platform 31 accordingly, and then the cleaning platform 31 adsorbs and stabilizes the strip 100. After that, the cleaning mechanism 32 cleans the strip 100 to form a cleaning tank 130, and the dust removal mechanism 33 removes the dust generated by the cleaning. The cleaning main drive mechanism 34 in this embodiment can adopt the cooperation of a private service motor and a moving roller. The cleaning mechanism 32 can adopt an existing laser cleaning machine, which has a plurality of laser cleaning heads 321 arranged side by side, and each laser cleaning head 321 can be displaced and swung.

[0049] Continue to refer to Figures 3 to 6 , Figure 5 Schematic diagram of the structure of the cleaning platform in this embodiment. Figure 6Schematic diagram of the structure of the bottom plate in this embodiment. Furthermore, the cleaning platform 31 includes a mounting seat 311, a bottom plate 312, a suction plate 313 and a solenoid valve 314. The bottom plate 312 is arranged on the mounting seat 311, and the bottom plate 312 has an adsorption chamber 3121, and the adsorption chamber 3121 has an air groove 31211. The suction plate 313 is arranged on the bottom plate 312, and the suction plate 313 and the bottom plate 312 are sealed together. The suction plate 313 has an adsorption hole 3131, and the adsorption hole 3131 is connected to the adsorption chamber 3121. The strip 100 passes through the surface of the suction plate 313 and covers the adsorption hole 3131. The solenoid valve 314 is arranged on the mounting seat 311, the solenoid valve 314 is close to the bottom plate 312, and the solenoid valve 314 is connected to the air groove 31211 in the adsorption chamber 3121. In specific application, the vacuum pump is connected to the electromagnetic valve 314, the electromagnetic valve 314 is opened, and the vacuum pump is started to evacuate the adsorption chamber 3121, so that negative pressure is formed in the adsorption chamber 3121, and the negative pressure is transmitted to the upper surface of the suction plate 313 through the adsorption hole 3131, so as to adsorb the strip 100 thereon, and realize the fixation of the strip 100 on the suction plate 313. In this embodiment, there are two bottom plates 312, and each bottom plate 312 has five adsorption chambers 3121. The five adsorption chambers 3121 are relatively independent, that is, each adsorption chamber 3121 can be individually controlled by the electromagnetic valve 314 to realize the adsorption of the strip 100 in different regions, for example, adsorption is performed on the position of the strip 100 with the coating film 120, or only the positions of the coating film 120 at odd positions of the strip 100 are adsorbed, or only the positions of the coating film 120 at even positions of the strip 100 are adsorbed. In addition, it can also avoid the situation where the area of ​​the strip 100 is too small to completely cover all the adsorption holes 3131 of the suction plate 313, so that when vacuuming, the atmosphere enters the adsorption chamber 3121 through the exposed adsorption holes 3131, and releases part of the vacuum negative pressure in the adsorption chamber 3121, which will not only cause the cleaning platform 31 to be unable to firmly adsorb the strip 100, but also cause energy waste. Correspondingly, the number of suction plates 313 is also two, and the number of solenoid valves 314 is ten; of course, the number of adsorption chambers 3121 and solenoid valves 314 can be adaptively increased or decreased according to actual needs. The above is only one implementation of this embodiment and should not be limited to this.

[0050] Preferably, the cleaning platform 31 also includes a filter 315. The filter 315 is clamped on the buckle 3111 set on the mounting seat 311, and the filter 315 is fixed by the buckle 3111, which is convenient for installation and disassembly and easy to use. The air inlet of the filter 315 is connected to the adsorption chamber 3121, and the air outlet of the filter 315 is connected to the solenoid valve 314. In specific application, the filter 315 filters and collects pollutants sucked from the atmosphere to prevent the pollutants from polluting the system, and at the same time, prevents the solid particles contained in the pollutants from damaging the solenoid valve 314 or other parts. Preferably, the cleaning platform 31 also includes a manifold 316. The manifold 316 is connected to the solenoid valve 314. In specific application, each adsorption chamber 3121 is connected to the manifold 316 through a solenoid valve 314, so that the production cost can be effectively saved, and at the same time, it is avoided that multiple manifolds 316 are easily entangled. In the preferred application scheme, the vacuum pump is connected to the manifold 316. When the solenoid valve 314 is in the closed state, the vacuum pump evacuates the air in the manifold 316, so that the manifold 316 is in a negative pressure state. When the strip 100 needs to be adsorbed, the solenoid valve 314 is opened. At this time, the manifold 316 can generate an instantaneous negative pressure to achieve rapid adsorption of the strip 100. Preferably, the cleaning platform 31 also includes a pressure sensor 317. The pressure sensor 317 is arranged on the mounting seat 311. The pressure sensor 317 is connected to the adsorption chamber 3121. The pressure sensor 317 monitors the pressure value of the negative pressure. In this embodiment, the pressure sensor 317 is a digital pressure sensor 317. The digital pressure sensor 317 can intuitively reflect the size of the pressure value, which is convenient for observation. In order to facilitate the later maintenance of the cleaning platform 31, the cleaning platform 31 also includes a sliding assembly 318. The sliding assembly 318 includes a mounting panel 3181 and a sliding plate 3182. The sliding plate 3182 is slidably disposed on the mounting panel 3181, and the mounting seat 311 is disposed on the sliding plate 3182. In specific applications, the sliding plate 3182 can be slidably disposed on the mounting panel 3181 through a guide rail slider. In order to reduce sliding friction, in this embodiment, a sliding member 3183 is provided on the sliding plate 3182 so that the sliding plate 3182 is slidably disposed on the mounting panel 3181. The sliding member 3183 is a cam bearing follower. Preferably, a guide plate 3184 is provided on the mounting panel 3181, and the guide plate 3184 has a guide groove (not shown in the figure), and one end of the rotating shaft of the sliding member 3183 is located in the guide groove. When maintenance of the cleaning platform 31 is required, the sliding plate 3182 is pulled, and the sliding member 3183 rolls on the upper surface of the mounting panel 3181 driven by the sliding plate 3182. During the rolling of the sliding member 3183, the guide groove guides the rolling member. Similarly, after the maintenance is completed, the cleaning platform 31 can be returned to the predetermined position by repeating the above actions in reverse. The operation is simple and convenient.

[0051] Continue to refer to Figure 7 , Figure 7 It is a structural schematic diagram of the dust removal mechanism in this embodiment. Furthermore, the dust removal mechanism 33 includes a mounting plate 331, a dust removal component 332 and a dust exhaust component 333. An adjustment slot 3311 is provided on the mounting plate 331. The dust removal component 332 is arranged in the adjustment slot 3311 of the mounting plate 331. The dust exhaust component 333 is located on one side of the mounting plate 331. In specific application, the position of the dust removal component 332 in the adjustment slot 3311 is adjusted so that the dust suction port of the dust removal component 332 faces the position to be dusted on the cleaning platform 31, and the dust sucked away by the dust removal component 332 is discharged through the dust exhaust component 333. Preferably, the dust removal component 332 includes a dust removal mounting plate 3321 and a dust removal pipe 3322. One end of the dust removal mounting plate 3321 is arranged in the adjustment slot 3311 by a fastening screw. The dust removal pipe 3322 is arranged at the other end of the dust removal mounting plate 3321. In this embodiment, the dust removal mounting plate 3321 is "L" shaped, one end of the dust removal mounting plate 3321 is a bent end, and the other end of the dust removal mounting plate 3321 is an unbent end. The position of the dust removal assembly 332 can be changed by changing the position of the fastening screw in the adjustment slot 3311, so that the dust suction port faces the position to be dusted, and the adjustment is convenient. It should be noted that in this embodiment, the number of dust removal mounting plates 3321 and dust removal pipes 3322 is ten, and the ten dust removal pipes 3322 face the ten positions to be dusted of the strip 100, so that dust removal can be performed at multiple positions at one time; of course, the number of dust removal mounting plates 3321 and dust removal pipes 3322 can be adaptively increased or decreased according to actual needs. The above is only one implementation of this embodiment and should not be limited to this. Preferably, the dust exhaust assembly 333 includes a dust exhaust mounting seat 3331, a dust exhaust pipe 3332 and a control switch 3333. The dust exhaust mounting seat 3331 is located on one side of the mounting plate 331. The dust exhaust pipe 3332 is arranged on the dust exhaust mounting seat 3331, and the dust exhaust pipe 3332 is connected to the dust outlet of the dust removal pipe 3322. The control switch 3333 is arranged on the dust exhaust mounting seat 3331, and the control switch 3333 is connected between the dust outlet of the dust removal pipe 3322 and the dust exhaust pipe 3332. In specific application, the number of control switches 3333 corresponds to the number of dust removal pipes 3322, which is also ten. The ten control switches 3333 respectively control the connection and disconnection of the ten dust removal pipes 3322 and the dust exhaust pipe 3332. In this way, the ten dust removal pipes 3322 are individually controlled. When only one or several positions need to be dusted, the control switches 3333 of the positions that do not need dust removal only need to be turned off. It should be noted that the dust exhaust mounting seat 3331 has a switch adjustment hole 33311, and the twisting part of the control switch 3333 is exposed in the switch adjustment hole 33311. The control switch 3333 can only rotate within the range of the switch adjustment hole 33311. The switch adjustment hole 33311 limits the control switch 3333. By rotating the control switch 3333 to different rotation angles, the dust removal force can be adjusted to achieve a good dust removal effect.

[0052] In the present embodiment, the number of mounting plates 331 is two, and correspondingly, the number of dust removal components 332 and dust exhaust components 333 is also two. The two dust removal components 332 are respectively arranged on the two mounting plates 331, and the two dust exhaust components 333 are respectively located on both sides of the two mounting plates 331. The dust sucked away by the two dust removal components 332 is discharged through the two dust exhaust components 333; of course, the number of mounting plates 331 can be adaptively increased or decreased according to actual needs, and correspondingly, the number of dust removal components 332 and dust exhaust components 333 is also adaptively increased or decreased according to actual needs to correspond to the mounting plates 331. The above is only one implementation of the present embodiment and should not be limited to this.

[0053] Refer to Figure 8 , Figure 8 The schematic diagram of the structure of the dust removal component, the angle adjustment component and the lifting component in the embodiment of the present invention. The dust removal mechanism 33 also includes an angle adjustment component 334, and the mounting plate 331 is arranged on the angle adjustment component 334. The angle adjustment component 334 includes a fixed block 3341 and an angle adjustment member 3342. The mounting plate 331 is arranged on the fixed block 3341 through the angle adjustment member 3342, and the angle adjustment member 3342 is a screw. The inclination angle of the mounting plate 331 can be adjusted by the angle adjustment member 3342. After adjustment, the mounting plate 331 and the fixed block 3341 are locked and fixed so that the relative position of the two will not change, so that the dust suction ports of the two dust removal components 332 are not directly opposite, and the suction forces generated by the two dust removal components 332 will be prevented from offsetting each other, so that the dust removal effect is deteriorated. Preferably, the dust removal mechanism 33 also includes a lifting component 335. The lifting component 335 includes a lifting mounting block 3351 and a lifting driving member 3352. The lifting mounting block 3351 is set at a predetermined position. The lifting drive member 3352 is arranged on the lifting mounting block 3351. The lifting drive member 3352 is a cylinder. The output end of the lifting drive member 3352 is connected to the lifting plate 3353. The lifting plate 3353 is connected to the fixing block 3341 through the connecting rod 3354. The lifting assembly 335 also includes a linear bearing 3355, which is sleeved on the connecting rod 3354. In specific application, the lifting drive member 3352 generates a driving force to drive the lifting plate 3353 to move in a direction away from the strip 100, and the lifting plate 3353 drives the connecting rod 3354 and the fixing block 3341 to move in a direction away from the strip 100. During the movement, the linear bearing 3355 guides the connecting rod 3354, and the fixing block 3341 drives the mounting plate 331 to move in a direction away from the strip 100, so that there is enough space between the mounting plate 331 and the strip 100 to facilitate the strip 100 to be threaded.

[0054] Re-reference Figures 1 to 3Furthermore, the second buffer device 6 is located on the side of the first cleaning device 3 away from the first deflection correction device 4. The structure and operating principle of the second buffer device 6 in this embodiment are consistent with those of the first buffer device 2, and will not be repeated here.

[0055] Re-reference Figures 1 to 3 Furthermore, the first cleaning device 3 further includes a first length measuring mechanism 35. The first length measuring mechanism 35 is located between the second buffer device 6 and the cleaning main drive mechanism 34, and is used to detect the real-time length of the strip 100. It is understandable that, in actual application, the servo motor of the cleaning main drive mechanism 34 will have an error when pulling the strip 100 of length "L". For example, the set fixed-segment strip length "L" is 100 length units. The servo motor of the cleaning main drive mechanism 34 drives the moving roller to move 100 length units according to the control command. However, due to the relative sliding between the strip 100 and the moving roller, the moving roller moves 100 length units, but the strip 100 actually pulled by the moving roller only moves 99 length units, of which 1 length unit is the strip moving error, that is, the actual strip moving distance deviation. This distance deviation will affect the laser cleaning accuracy of the cleaning mechanism 32, and then affect the quality of the cleaning tank 130. Therefore, it is necessary to compensate for the distance deviation to ensure and improve the laser cleaning accuracy. If compensation is to be performed, it is necessary to first obtain the distance deviation and monitor the actual real-time length of the strip 100. The first length measuring mechanism 35 in this embodiment detects the real-time running length of the strip 100 through the cooperation of the length measuring roller and the pressure roller. The strip 100 is wound around the length measuring roller, and the pressure roller is pressed on the strip 100, so that the strip 100 fits the length measuring roller, so that the length measuring roller can rotate with the movement of the strip 100. The real-time rotation angle of the length measuring roller is obtained by setting an encoder on the length measuring roller. When the diameter of the length measuring roller is known, the circumference generated by the rotation of the length measuring roller can be calculated, thereby obtaining the real-time length of the fixed-segment running of the strip 100. Then, the real-time length is compared with the fixed-segment running length "L" to calculate the distance deviation. Then, the laser cleaning head 321 of the cleaning mechanism 32 moves and compensates according to the distance deviation, and then performs the cleaning action to improve the accuracy of cleaning.

[0056] Refer to Fig. 9 , Fig. 9It is a schematic diagram of the structure of the first detection device in this embodiment. It can be understood that the first deviation correction device 4 will still have a certain error in the deviation correction of the strip 100 in the running direction. This error will cause the coating reference position to form an angle deviation with the running direction and the width direction of the strip 100 respectively. This angle deviation will affect the accuracy of the cleaning mechanism 32 during cleaning. Therefore, the cleaning mechanism 32 also needs to compensate for the angle deviation by swinging the laser cleaning head 321, which further improves the cleaning accuracy and ensures the cleaning quality. The first detection device 5 in this embodiment also includes two first detectors 51 and two second detectors 52. The two first detectors 51 are located on one side of the strip 100 and are arranged side by side along the width direction of the strip 100. There is a gap between the two first detectors 51. The two first detectors 51 cooperate to detect the deviation angle α of the strip 100 in the running direction. Specifically, according to the formula cosα=ΔL1 / L1, L1 is the preset width of the cleaning tank 130. Since the cleaning tank 130 is preset according to actual needs, its width is known. When the coating reference position 140 deviates in the running direction, the numerical deviation of the coating reference position 140 can be obtained by respectively detecting the numerical deviation of the coating reference position 140 by two first detectors 51 arranged in the width direction of the strip 100. The first detector 51 in this embodiment can adopt a photoelectric sensor with a regional detection function. Therefore, the deviation angle α of the strip 100 in the running direction is calculated according to the above formula cosα=ΔL1 / L1. The two second detectors 52 are located on one side of the strip 100 and are arranged side by side along the running direction of the strip 100. There is a gap between the two second detectors 52. The two second detectors 52 cooperate to detect the deviation angle θ in the width direction of the strip 100. Specifically, according to the formula tanθ=ΔL2 / L2, L2 is the preset detection distance, that is, the interval between the two second detectors 52, which is known, and ΔL2 is the position deviation of the coating reference position in the width direction of the strip. When the coating reference position 140 is offset in the width direction of the strip 100, the numerical deviation of the coating reference position 140 can be obtained by respectively detecting the numerical deviation of the coating reference position 140 by the two second detectors 52 set in the running direction of the strip 100. The second detector 52 in the embodiment can be a photoelectric sensor with an optical fiber reflection function. Therefore, the deviation angle θ of the strip 100 in the width direction of the strip 100 is calculated according to the above formula tanθ=ΔL2 / L2. If the distance deviation of the strip 100 during its running is defined as ΔY, the compensation process of the laser cleaning head 321 of the cleaning mechanism 32 is as follows: the laser cleaning head 321 is first offset by ΔY in the running direction of the strip 100, then rotates by e in the width direction of the strip 100, and finally rotates by α in the running direction of the strip 100. After compensating for the distance deviation and the angle deviation in turn, precise laser cleaning is performed to form a cleaning groove 130.

Preferably, the laser cleaning device also includes a second detection device 9.

Preferably, the laser cleaning device also includes a third cache device 10. The third cache device 10 receives the cleaned strip and caches the strip.

It can be understood that the base tape 110 has two sides, which are defined as side A and side B in this embodiment. Both sides of the base tape 110 have a coating film 120, that is, both sides A and B of the strip material 100 have a coating film 120. According to different welding requirements, it is necessary to clean the side A of the strip material 100 on one side to form a cleaning tank 130, or it is necessary to clean both sides AB of the strip material 100, and form a one-to-one corresponding cleaning tank 130 on both sides AB of the base tape 110.

Preferably, the plurality of third face-changing rollers 713 are connected by chains to achieve synchronous rotation.

[0060] When it is necessary to clean the A surface of the strip 100, the strip 100 passing through the second buffer device 6 first passes through the first deflection correction roller 42 and the second deflection correction roller 43 of the second deflection correction device 8, then extends to the top of the cleaning platform 31, then extends and is wound around the cleaning main drive mechanism 34 of the second cleaning device 7, and then extends to the second buffer device 10 for buffering. In specific applications, the first cleaning device 3 performs laser cleaning on the odd-numbered coating film 120 of the A surface of the strip 100, or performs laser cleaning on the even-numbered coating film 120 of the A surface of the strip 100, and the second cleaning device 7 performs laser cleaning on the even-numbered coating film 120 of the A surface of the strip 100, or performs laser cleaning on the odd-numbered coating film 120 of the A surface of the strip 100. In this way, the coating film 120 of the A surface of the strip 100 can be cleaned at two stations at the same time in the laser cleaning device in this embodiment, thereby improving the cleaning efficiency.

[0061] When it is necessary to clean the AB surfaces of the strip 100, the strip 100 passing through the second buffer device 6 first passes under the first deflection correction roller 42 of the second deflection correction device 8, passes over the second deflection correction roller 43 of the second deflection correction device 8, and then passes through a plurality of first face-changing rollers 711 arranged counterclockwise and is changed 180 degrees, and then passes through two horizontally arranged second face-changing rollers 712, so as to be adsorbed by the cleaning platform 31 of the second cleaning device 7, and then continues to pass through a plurality of third face-changing rollers 713 arranged clockwise and makes the strip 100 extend and transfer toward the cleaning main drive mechanism 34 of the second cleaning device 7, and then is buffered by the third buffer device 10. In specific applications, the first cleaning device 3 continuously cleans the coating film 120 on the A surface of the strip 100, and the second cleaning device 7 continuously cleans the coating film 120 on the B surface of the strip 100. In this way, the laser cleaning equipment in this embodiment can realize single-sided or double-sided cleaning of the strip 100 according to actual needs, thereby increasing its applicability.

[0062] Re-reference Figure 1 Furthermore, the laser cleaning device in this embodiment also includes a dust removal device 20. The dust removal device 20 receives the strip material cached by the third buffer device 10 and removes dust from the strip material. Specifically, the dust removal device 20 is arranged on the frame 200 and is located on the side of the third buffer device 10 away from the second cleaning device 7.
