In order to further understand the contents, features and effects of the present invention, the following embodiments are illustrated and described in detail with reference to the accompanying drawings:
example one
Referring to fig. 1, fig. 1 is a flowchart of a laser cleaning method according to a first embodiment. The laser cleaning method in the embodiment includes the following steps:
s1, obtaining the coating reference level of the strip coating film.
And S2, performing fixed-section tape running of a preset length on the strip according to the coating reference position.
And S3, carrying out laser cleaning on the coating film of the strip after the fixed-length tape transport.
Before the coating film of the strip material is subjected to laser cleaning, the coating reference position is detected, and the strip material is subjected to positioning tape transport with a preset length according to the coating reference position, so that the movement of the coating film is determined, the position to be cleaned of the coating film of the strip material can be accurately determined, and the consistency of the position where the cleaning groove is formed is ensured.
Preferably, in step S3, the coating film of the strip material after the constant-length running is laser-cleaned, and a cleaning bath is formed. The shape and size of the cleaning tank can be set according to actual requirements.
With continuing reference to fig. 2 and 3, fig. 2 is a flow chart of obtaining a coating reference level of a coating film of a strip material in the first embodiment, and fig. 3 is a schematic view of a structure of the strip material in the first embodiment. Further, in step S1 of the present embodiment, the obtaining of the coating reference level of the strip coating film includes the following sub-steps:
and S11, detecting the passing strip. The strip material comprises a base band and a plurality of coating films, and the plurality of coating films are sequentially coated on the base band at intervals.
S12, the boundary position between the coating film and the base tape is identified to obtain the coating reference level.
As shown in fig. 3, the strip material 100 includes a base tape 110, a coating film 120, and a cleaning bath 130. The number of the coating films 120 is plural, and plural coating films 120 are sequentially coated on the surface of the base tape 110 at intervals, and preferably, the intervals between two adjacent coating films 120 are the same. The initial end 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 a laser cleaning method, so that the base tape 110 is exposed out of the coating film 120 for facilitating the subsequent welding requirement. The structure of performing the segment coating on the base tape 110 and forming the coating films 120 arranged at intervals can be realized by the existing coating process, and will not be described herein. It should be noted that the distance between two adjacent coating films 120 in the plurality of coating films 120 is determined by the coating process, and preferably, the distance between two adjacent coating films 120 is the same, but the difference between the two adjacent coating films 120 may also occur due to the coating process error, which is also the reason for the poor position consistency of the cleaning grooves formed by the conventional laser cleaning method.
The strip material 100 coated with the coating film 120 is transported in a roll form, and the strip material 100 is also fed in a roll form. In a specific application, the unwinding mechanism may be used to unwind the coiled strip material 100, and then the buffering mechanism may buffer the unwound strip material 100. The unwinding mechanism and the caching mechanism can adopt the existing devices, and are not described herein again. In step S11, the buffered tape material 100 is extended and passed through the detection mechanism, and the detection mechanism detects the passed tape material 100. In step S12, the boundary position between the coating film and the base tape is recognized by the detection means, and the coating reference level is obtained. In this embodiment, the detection mechanism is a photosensor. It can be understood that the coating film 120 is coated on the base tape 110, the base tape 110 is separated from the coating film 120, the base tape 110 and the coating film 120 have different colors, and at the initial position of the coating film 120 coated on the base tape 110, the base tape 110 and the coating film 120 form a boundary, i.e. the coating reference position 140 in the present embodiment, the colors of the base tape 110 and the coating film 120 are different, and different photoelectric reactions are generated when the photoelectric sensors detect, so that the coating reference position 140 of the passing strip material 100 can be detected, and the coating reference position 140 is obtained, i.e. the initial position of each coating film 120 on the base tape 110 is obtained. Before any one of the coating films 120 is subjected to laser cleaning, the coating reference level 140 of the coating film 120 needs to be detected, so that the cleaning position of the current coating film 120 is determined by the coating reference level 140 of the coating film 120 again, and thus the influence of different distances between two adjacent coating films 120 can be avoided.
With continuing reference to fig. 3 and 4, fig. 4 is a flowchart of a mid-span tape deck according to an embodiment. Further, in step S2, the step of winding the strip material in fixed sections with preset lengths according to the coating reference positions includes the following sub-steps:
and S21, presetting a cleaning position.
S22, calculating the fixed segment tape length according to the coating reference position and the preset cleaning position.
And S23, performing fixed-section tape running according to the fixed-section tape running length.
In this embodiment, the coating film 120 of the strip material 100 is laser cleaned by a laser cleaning mechanism to form the cleaning tank 130, and the existing laser cleaning mechanism can be used for specific applications, which is not described herein again. While it is artificially set which specific position on the coating film 120 the cleaning tank 130 is formed, in practical applications, the position of the cleaning tank 130 on the coating film 120 is determined according to actual needs or customer needs, that is, the forming position of the cleaning tank 130 is preset and known, that is, the cleaning position is preset in step S21. In step S22, as shown in fig. 3, when the position of the cleaning tank 130 is known, the position of the coating reference point 140 is measured in real time in step S1, and the fixed segment running length "L" is calculated. In step S23, the tape pulling mechanism pulls the tape 100 according to the fixed length "L", that is, the tape 100 is pulled to move by the fixed length "L" distance from the coating reference position 140, so that the position to be cleaned on the coating film 120 is just opposite to the cleaning position of the laser cleaning mechanism, and the laser cleaning mechanism performs laser cleaning on the position to form the cleaning tank 130, the position formed by the cleaning tank 130 is accurate, and each tape-moving takes the coating reference position 140 determined again as the calculation starting point, and reaches the preset cleaning position after the fixed length "L" is moved, thereby ensuring that the position where the cleaning tank 130 is formed each time has high consistency. The drawstring mechanism can adopt the existing drawstring mechanism.
With continued reference to fig. 5, fig. 5 is a schematic structural view of a belt material from another perspective in the first embodiment. It is understood that the base band 110 has two sides, which are defined as a-side and B-side in this embodiment. Both sides of the base tape 110 have the coating film 120, that is, both the a-side and the B-side of the strip material 100 have the coating film 120. According to different welding requirements, the a side of the strip material 100 needs to be cleaned to form the cleaning tank 130, or both the AB sides of the strip material 100 need to be cleaned to form the cleaning tanks 130 corresponding to each other on the AB sides of the base band 110. Therefore, in step S3, the coating film of the strip after the constant-length running is laser-cleaned, and two kinds of cleaning S3a and S3b can be performed, respectively:
s3a is executed, and the coating film on the A side of the strip material is cleaned by laser.
S3b is executed, and the coating film of the strip after the fixed-length tape winding is subjected to laser cleaning, and the method comprises the following substeps:
and S3b1, performing laser cleaning on the coating film on the surface A of the strip material.
And S3b2, turning over the belt material.
And S3B3, performing laser cleaning on the coating film on the B side of the strip.
Thus, according to the actual requirement, the single-sided cleaning of the strip material 100 or the double-sided cleaning of the strip material 100 can be realized.
Preferably, in step S3a, the laser cleaning of the coating film on the a-side of the strip material includes:
and S3a1, performing laser cleaning on the odd-numbered coating film on the surface A of the strip material or performing laser cleaning on the even-numbered coating film on the surface A of the strip material.
And S3a2, performing laser cleaning on the even-numbered coating film on the surface A of the strip material, or performing laser cleaning on the odd-numbered coating film on the surface A of the strip material.
When the cleaning device is specifically applied, two groups of detection mechanisms, laser cleaning mechanisms and belt pulling mechanisms are respectively arranged at the front and the back, and the detection mechanisms, the laser cleaning mechanisms and the belt pulling mechanisms in the former group are matched to clean the coating film 120 with odd digits to form a cleaning tank 130; the latter group of the detection mechanism, the laser cleaning mechanism, and the draw belt mechanism cooperate to clean the even-numbered coating film 120 to form the cleaning tank 130. Or the detection mechanism, the laser cleaning mechanism and the belt pulling mechanism in the previous group are matched to clean the coating film 120 at the even number position to form a cleaning tank 130; the latter set of detection mechanism, laser cleaning mechanism, and draw tape mechanism cooperate to clean the odd-numbered coating film 120 to form the cleaning tank 130. That is to say, the detection mechanism, the laser cleaning mechanism and the drawstring mechanism in the former group are only matched to clean the coating film 120 on the surface a of the strip material 100 at intervals, and the part of the surface a which is not cleaned is cleaned by the detection mechanism, the laser cleaning mechanism and the drawstring mechanism in the latter group, so that two coating films 120 on the base band 100 can be cleaned synchronously at the same time, and the cleaning efficiency is improved.
Preferably, in step S3b, two sets of the detection mechanism, the laser cleaning mechanism and the tape pulling mechanism are also provided. In step S3b1, the coating film on the a side of the strip material is laser cleaned by the previous group of detecting mechanism, the laser cleaning mechanism and the belt pulling mechanism. Then, in step S3B2, the strip material is turned over, specifically, the detection mechanism in the next group detects that the strip material 100 is turned by 180 degrees by matching of a plurality of turning rollers, and then the detection mechanism extends to the laser cleaning mechanism in the next group, and then in step S3B3, the laser cleaning mechanism in the next group cleans the B surface of the turned strip material 100, so as to complete the AB surface and the AB surface of the strip material 100.
