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 utility model.

[0041] The embodiment of the utility model provides a laser cleaning device. Figure 1 The laser cleaning device of the utility model is a schematic structural diagram of an embodiment of the laser cleaning device, which includes an unwinding module 111 , a winding module 112 , a first tape connection platform 121 , a second tape connection platform 122 , a third tape connection platform 123 , a plurality of functional modules and a tape threading system 140 .

[0042] The first tape connection platform 121 is located at the unwinding module 111, the second tape connection platform 122 is located at the rewinding module 112, and the third tape connection platform 123 is located between the first tape connection platform 121 and the second tape connection platform 122. A plurality of functional modules are arranged between the unwinding module 111 and the rewinding module 112. The material tape unwound by the unwinding module 111 passes through the plurality of functional modules in sequence and is rewound by the rewinding module 112. In this embodiment, the plurality of functional modules between the first tape connection platform 121 and the third tape connection platform 123 include a laser cleaning module 130, and the plurality of functional modules between the third tape connection platform 123 and the second tape connection platform 122 include a laser cleaning module 130.

[0043] The belt threading system 140 is used to drive the head end of the material belt to pass through multiple functional modules in sequence to achieve belt threading. In this embodiment, a belt threading system 140 is arranged between the first belt connection platform 121 and the third belt connection platform 123, and between the third belt connection platform 123 and the second belt connection platform 122.

[0044] Figure 2 This is a schematic diagram of the structure of one set of belt threading system in one embodiment of the laser cleaning equipment of the utility model. Figure 3It is a structural schematic diagram of another tape threading system in an embodiment of the laser cleaning equipment of the utility model. According to the laser cleaning equipment of the embodiment of the utility model, it includes a first tape connection platform 121, a second tape connection platform 122, and a third tape connection platform 123. The third tape connection platform 123 is located between the first tape connection platform 121 and the second tape connection platform 122, and is located between two laser cleaning modules 130. Therefore, if the material tape is disconnected between the two laser cleaning modules 130 of the laser cleaning equipment, it is convenient to connect the tape between the two laser cleaning modules 130 through the third tape connection platform 123. In the above-mentioned laser cleaning equipment, a tape threading system 140 is arranged between the first tape connection platform 121 and the third tape connection platform 123, and between the third tape connection platform 123 and the second tape connection platform 122, so that the tape threading operation can be performed in stages in the laser cleaning equipment. If the material tape is broken between the first tape connection platform 121 and the third tape connection platform 123, the head end of the material tape is passed through the tape threading system 140 between the first tape connection platform 121 and the third tape connection platform 123 to be connected at the third tape connection platform 123; if the material tape is broken between the third tape connection platform 123 and the second tape connection platform 122, the head end of the material tape is passed from the third tape connection platform 123 to the second tape connection platform 122 through the tape threading system 140 between the third tape connection platform 123 and the second tape connection platform 122. According to the above laser cleaning equipment, if the material tape is broken inside the laser cleaning equipment, it is no longer necessary to perform the threading operation from the unwinding module 111 of the laser cleaning equipment to the winding module 112 through the entire laser cleaning equipment, which simplifies the path required for threading, thereby making it easier to thread the broken material tape.

[0045] In some embodiments, each belt threading system 140 includes a chain 141, a plurality of sprockets 142, and a belt threading drive assembly 143. The head end of the material belt can be connected to the chain 141. The plurality of sprockets 142 are arranged along a preset path, wherein the preset path passes through a plurality of functional modules, and the chain 141 is meshed with the plurality of sprockets 142, so that the chain 141 extends along the preset path and can transmit motion along the sprockets 142. The belt threading drive assembly 143 is connected to the chain 141 in a transmission manner, and the belt threading drive assembly 143 is used to drive the chain 141 to transmit motion.

[0046] In some embodiments, the preset path is a closed path, and the chain 141 moves in a circular motion under the drive of the threading drive assembly 143. After the head end of the material belt is connected to the chain 141, the head end of the material belt moves along the preset path with the chain 141 to realize the threading operation.

[0047] In some embodiments, the chains 141 are arranged in pairs, and the two sides of the material belt can be connected to the corresponding pairs of chains 141. The sprockets 142 cooperate with the chains 141, so the sprockets 142 are also arranged in pairs.

[0048] Figure 4 The diagram is a three-dimensional schematic diagram of one of the sprockets in one embodiment of the laser cleaning device of the utility model. In some embodiments, the belt threading system 140 further includes a protective cover 144, which is disposed on the outer periphery of the sprocket 142, and an opening K1 is disposed on the circumferential wall surface of the protective cover 144 for the chain 141 to pass through.

[0049] In some embodiments, the circumferential wall of each protective cover 144 is provided with two openings K1, and the positions of the two openings K1 are arranged according to the extension direction of the chain 141 at that location, wherein one opening K1 allows the chain 141 upstream of the sprocket 142 at that location to pass through the protective cover 144, and the other opening K1 allows the chain 141 downstream of the sprocket 142 at that location to pass through the protective cover 144. By providing the protective cover 144, the sprocket 142 in the protective cover 144 and the chain 141 at that location can be protected.

[0050] Figure 5 1 is a three-dimensional schematic diagram of a belt drive assembly in an embodiment of the laser cleaning device of the utility model. In some embodiments, the belt drive assembly 143 includes a drive motor 1431, a reducer 1432 and a driving wheel 1433, the drive motor 1431 is connected to the driving wheel 1433 through the reducer 1432, and the chain 141 is meshed with the driving wheel 1433.

[0051] In this embodiment, the chains 141 are arranged in pairs, so the driving wheels 1433 are also arranged in pairs. In some embodiments, the belt drive assembly 143 further includes a synchronization rod 1434, which connects the paired driving wheels 1433 synchronously.

[0052] In some embodiments, the protective cover 144 may also be disposed on the outer periphery of the driving wheel 1433 .

[0055] Multiple belt-threading sprockets 142b are arranged in sequence between the end node sprocket 142a and the belt-threading drive assembly 143 and pass through multiple functional modules, so that a portion of the chain 141 forms a belt-threading path P2 extending through multiple functional modules between the end node sprocket 142a and the belt-threading drive assembly 143.

[0056] A plurality of auxiliary rotating sprockets 142c are sequentially arranged between the belt threading drive assembly 143 and the end node sprocket 142a, so that a portion of the chain 141 forms a rotating path P3 between the belt threading drive assembly 143 and the end node sprocket 142a, and the rotating path P3 is connected to the belt threading path P2 to form a closed loop path.

[0057] By setting the threading sprocket 142b, a portion of the chain 141 forms a threading path P2 extending through multiple functional modules between the end node sprocket 142a and the threading drive assembly 143. Driven by the threading drive assembly 143, the chain 141 can drive the material belt to pass through the threading path P2 to complete the threading of the material belt. By setting the auxiliary rotating sprocket 142c, a rotating path P3 is formed. The rotating path P3 is connected to the threading path P2 as a closed loop path. Driven by the threading drive assembly 143, the chain 141 circulates to ensure the continuity of the threading operation.

[0058] In some embodiments, the plurality of functional modules further include a tension swing arm module 151, an iron removal module 152, a buffer module 160, a tension detection module 170, a deviation correction module 153, etc. In this embodiment, the belt threading path P2 formed by the chain 141 of the belt threading system 140 between the first belt connection platform 121 and the third belt connection platform 123 passes through the tension swing arm module 151, the iron removal module 152, a buffer module 160, a tension detection module 170, a deviation correction module 153, a laser cleaning module 130, and another buffer module 160 in sequence.

[0059] In some embodiments, the auxiliary return sprocket 142c includes a tensioning sprocket 142d, and the laser cleaning device further includes a tensioning adjustment component.

[0060] Figure 6It is a three-dimensional schematic diagram of the tensioning sprocket and the tensioning adjustment assembly in one embodiment of the laser cleaning equipment of the utility model. The tensioning adjustment assembly 180 is connected to the tensioning sprocket 142d and is used to adjust the position of the tensioning sprocket 142d. The tensioning adjustment assembly 180 includes a fixed frame 181, a movable block 182, a support rod 183 and an adjusting member 184. The fixed frame 181 is provided with a guide groove 1811 extending along a preset direction, and the movable block 182 is movably arranged in the guide groove 1811. The support rod 183 is arranged on the movable block 182. The tensioning sprocket 142d is rotatably connected to the support rod 183. The adjusting member 184 is connected to the fixed frame 181 and the movable block 182, and the adjusting member 184 can adjust the movable position of the movable block 182 along the guide groove 1811.

[0061] By providing the tensioning adjustment component 180 and the tensioning sprocket 142d, the sprocket 142 of the closed-loop structure can be tensioned, thereby ensuring the stability of the driving of the chain 141 by the belt driving component 143.

[0062] In some embodiments, each functional module includes at least one roller, and when the laser cleaning device is in normal working state, the material belt is wound around the rollers of multiple functional modules along a preset material belt working path P1.

[0063] In some embodiments, the belt threading sprocket 142b includes a coaxial sprocket 142e. The coaxial sprocket 142e is coaxially connected to a specific roller and is rotatably arranged with respect to each other.

[0064] In some embodiments, the belt threading sprocket 142b includes a position-avoiding sprocket 142f. The position-avoiding sprocket 142f is arranged away from the belt working path P1, so that the chain 141 at the position engaged with the position-avoiding sprocket 142f avoids a part of the structure of the functional module.

[0065] In the above embodiment, the belt threading sprocket 142b includes an avoidance sprocket 142f. When the chain 141 passes through the avoidance sprocket 142f, it can avoid the partial structure of the functional module to avoid interference between the belt threading system 140 and the partial structure of the functional module, thereby ensuring that the functions of each functional module of the laser cleaning equipment are not affected by the belt threading system 140 under normal working conditions.

[0066] In some embodiments, the avoidance sprocket 142f includes a steering sprocket 142g, and the steering sprocket 142g is used to redirect the extension direction of the chain 141 at the steering sprocket 142g relative to the material belt working path P1.

[0067] In some embodiments, the avoidance sprocket 142f includes a distance-avoiding sprocket 142h, and the distance-avoiding sprocket 142h is used to keep the chain 141 at the distance-avoiding sprocket 142h away from a specific structure of the functional module.

[0068] The positions of the steering sprocket 142g and the avoidance sprocket 142h can be set according to the avoidance requirements of certain structures of the functional module. When the chain 141 is required to avoid the position of the movable structure of the functional module, the steering sprocket 142g can be set there, or the steering sprocket 142g and the avoidance sprocket 142h can be set at the same time. When the specific structure of the functional module needs to maintain a large distance from the chain 141 or the sprocket 142 to avoid the position, the avoidance sprocket 142h can be set there.

[0069] In some embodiments, the functional module includes a cache module 160 .

The cache driving member 163 is transmission-connected to the movable frame 162 to drive the movable frame 162 to slide relative to the cache module bracket 161. Each fixed roller 164 is rotatably mounted on the cache module bracket 161, and multiple fixed rollers 164 are parallel to each other and spaced apart in the lateral direction. Each cache roller 165 is rotatably mounted on the movable frame 162, and at least two cache rollers 165 are parallel to each other and spaced apart in the lateral direction. Each cache roller 165 is located between two adjacent fixed rollers 164 in the lateral direction. At least two cache rollers 165 can approach or move away from multiple fixed rollers 164 along the movable frame 162, and the material belt is alternately wound around the fixed rollers 164 and the cache rollers 165.

[0071] In this embodiment, each fixed roller 164 is connected to a coaxial sprocket 142e, a steering sprocket 142g is arranged between the fixed roller 164 and the buffer roller 165, and a avoidance sprocket 142h is provided on the side of each buffer roller 165 away from the fixed roller 164.

[0072] In the above embodiment, the cache roller 165 can move closer to or away from the fixed roller 164 along with the movable frame 162, and the avoidance sprocket 142h is located on the side of the cache roller 165 away from the fixed roller 164, and when the cache roller 165 moves to the maximum stroke away from the fixed roller 164, there is still a gap between the avoidance sprocket 142h and the cache roller 165, thereby avoiding the interference of the belt threading system 140 with the cache roller 165 of the cache module 160, thereby ensuring that the cache module 160 can run smoothly under the normal working state of the laser cleaning equipment.
