Abstract
Description
Technical Field
[0001] This application relates to the technical field of wire stripping equipment, and in particular, to a flat wire paint stripping device and method. Background Art
[0002] In the prior art, usually multiple lasers are used to emit laser light, and the laser light is output to one side or multiple sides of the copper flat wire simultaneously through galvanometric mirrors and field lenses, so as to remove the paint film on the surface of the copper flat wire and expose the bottom copper under the insulating paint film.
[0003] Currently, when stripping the paint from copper wires, the laser wavelengths used are usually in the range of invisible light. To ensure the visibility and safety of the laser beam, an indicating light is added to the laser to perform debugging, calibration, and safety monitoring of the laser.
[0004] However, due to the deviation between the indicating light and the actual laser beam, problems such as incomplete laser paint stripping or laser light leakage may occur during the actual processing. When multiple lasers perform simultaneous multi-sided processing, light leakage is likely to cause the problem of laser beam interception. The problem of laser beam interception will greatly increase the failure rate of the laser, resulting in the failure of the laser. Summary of the Invention

The four laser emission modules are arranged in pairs opposite to each other, and the flat wire is arranged on one side of the connection line between two opposite laser emission modules.
[0016] In one embodiment of the first aspect, a housing is arranged on the flat wire carrier seat. Two through holes are opened on the opposite sides of the housing to form a flat wire channel. The flat wire is arranged in the flat wire channel. Four processing channels are arranged on the circumference of the housing.

[0027] Determine that there is still a second light shielding sheet on the same side between the currently selected laser emission module and the flat wire. Among them, the second light shielding sheet on the same side is the second light shielding sheet of another laser emission module opposite to the currently selected laser emission module;
[0028] Adjust the position of the second light shielding sheet on the same side so that the second light shielding sheet on the same side is outside the actual light emission range of the currently selected laser emission module.
[0029] Compared with the prior art, the beneficial effects of the present application are as follows: The present application provides a flat wire paint stripping device, which includes a flat wire carrier seat, at least one laser emission module, and at least one first light shielding component. A flat wire is threaded through the flat wire carrier seat. There is an offset between the actual light-emitting range of the laser emission module and the central axis of the original light-emitting range of the laser emission module, preventing the actual light-emitting ranges of two relatively arranged laser emission modules from facing each other and reducing the risk of direct shooting.
[0030] And the flat wire is located within the actual light-emitting range of the laser emission module, so that the light emitted by the laser emission module irradiates the continuous first side and second side of the flat wire.

The first light shielding sheet is used to define the lower edge position of the actual light-emitting range and make the lower edge of the actual light-emitting range located within the first side, avoiding the laser irradiating the opposite laser emission module and causing a direct shooting problem. The second light shielding sheet is arranged on the side of the flat wire away from the current laser emission module. The second light shielding sheet blocks the light exceeding the edge of the second side away from the first side, avoiding light leakage and causing a direct shooting problem.

[0045] Flat wire paint stripping refers to the process of removing the insulation layer on the surface of a flat wire during wire processing.
[0046] As Figure 1 and Figure 2 As shown, the embodiments of this application provide a flat wire paint stripping device that uses a laser beam to irradiate the insulation layer to instantly vaporize or decompose it.
[0047] The flat wire paint stripping device of this application includes a flat wire carrier seat 110, at least one laser emission module 120, and at least one first light shielding component, and one first light shielding component corresponds to one laser emission module 120.
[0048] A housing 111 is provided on the flat wire carrier seat 110. Two through holes are opened on opposite sides of the housing 111, and a flat wire channel 114 is formed between the two through holes. The flat wire 200 is threaded through the flat wire channel 114. Four processing channels 112 are provided on the peripheral side of the housing 111. The laser emission module 120 is provided on the peripheral side of the housing 111, and the laser emission module 120 and the processing channels 112 are arranged opposite to each other. The first light shielding component is movably provided on the housing 111. The laser emitted by the laser emission module 120 irradiates the flat wire 200 inside the housing 111 through the processing channels 112, thereby cleaning the paint on the flat wire 200 to achieve the effect of laser paint stripping.
[0049] During the processing, by way of example, as Figure 1 and Figure 2As shown, the flat wire 200 advances in the flat wire channel 114 at a preset speed. The laser beam emitted by the laser emission module 120 on the right passes through the processing channel 112 on the right and irradiates the flat wire 200 in the housing 111 to strip the paint off the flat wire 200.
[0050] The laser emission module 120 includes a laser, a galvanometer scanner, and a field lens. The laser provides the processing laser beam for paint stripping; the field lens focuses the processing laser beam so that the focal position of the laser beam falls on the flat wire 200; the field lens is a motion mechanism that moves the laser beam within a preset plane by controlling the lens angle, forming the original light-emitting range 121 of the laser emission module 120. The original light-emitting range 121 is the maximum range that the laser beam can irradiate under the control of the field lens.
[0051] As Figure 1 shown, the cross-section of the flat wire 200 is rectangular, having four sides extending in the length direction. During actual processing, one or more of these four sides are the processing surfaces that need to have the paint stripped. For example, when it is necessary to strip the paint from two opposite sides of the flat wire, two laser emission modules 120 are set up to strip the paint from the two opposite sides of the flat wire 200 simultaneously, and the two laser emission modules 120 are arranged opposite to each other. If it is necessary to strip the paint from several sides of the flat wire 200, the corresponding number of laser emission modules 120 and the corresponding number of first light-shielding components can be set on the corresponding circumferential side of the flat wire 200.
[0052] However, due to the low control accuracy of the field lens and the deviation problem between the indicating light beam and the laser beam, even if a structure similar to a baffle is set between the flat wire and the corresponding laser emission module to block the excess laser beam, there will still be a situation where the paint on the edge position of the flat wire cannot be cleaned; or there will be laser light leakage between the baffle and the edge position of the flat wire, which is extremely likely to cause problems such as laser beam shooting at each other and potential safety hazards in laser processing.
[0053] To address the above problems, the actual light-emitting range 1212 of the laser emission module 120 is controlled by controlling the field lens, so that there is an offset between the center axis of the actual light-emitting range 1212 and the center axis of the original light-emitting range 121. And the position of the flat wire carrier 110 is set so that the flat wire 200 in the flat wire carrier 110 is located within the actual light-emitting range 1212 of the laser emission module 120. When multiple laser emission modules 120 are used to clean multiple sides of the flat wire 200 simultaneously, the actual light-emitting ranges 1212 of two opposite laser emission modules 120 will not cross in the center axis direction, which can reduce the problem of laser beam shooting at each other.
[0054] As Figure 1As shown, the flat wire 200 is located within the actual light-emitting range 1212 of the laser emission module 120, and there is an offset between the actual light-emitting range 1212 of the laser emission module 120 and the central axis 1211 of the original light-emitting range 121 of the laser emission module 120.
[0055] In other words, the actual light-emitting range 1212 is located in the upper half or the lower half of the original light-emitting range 121. Moreover, when there are two or four laser emission modules 120, the two opposite laser emission modules 120 can be installed horizontally or vertically, that is, the central axes 1211 of the two opposite laser emission modules 120 can coincide. And for the actual light-emitting ranges 1212 of the two opposite laser emission modules 120, they are both offset to the same side of the central axis 1211. For example Figure 1 as shown in, they are both offset above the central axis 1211. In this way, it is possible to prevent the actual light-emitting ranges 1212 of the two relatively arranged laser emission modules 120 from facing each other, reducing the risk of direct shooting.
[0056] Since the flat wire 200 is located within the actual light-emitting range 1212 and there is an offset between the actual light-emitting range 1212 and the central axis 1211 of the original light-emitting range 121 of the laser emission module 120, the light emitted by the laser emission module 120 can irradiate the continuous first side 210 and second side 220 of the flat wire 200. Among them, the first side 210 is the side of the flat wire 200 facing the central axis 1211 of the original light-emitting range 121 of the current laser emission module 120, and the second side 220 is the side of the flat wire 200 facing the current laser emission module 120.
[0057] For example, in Figure 1 the laser emission module 120 on the left is used to strip the paint from the second side 220 of the flat wire 200, and the actual light-emitting range 1212 is a range slightly larger than the second side 220. The laser beam in the actual light-emitting range 1212 will not only irradiate the first side 210 and the second side 220, but also leak light from the upper edge of the second side 220 and the right edge of the first side 210.
[0058] In order to ensure that the sides of the flat wire can be fully cleaned and reduce the light leakage of the laser beam from the edges of the flat wire, in this application, a first light-shielding component is used to block part of the laser beam in the actual light-emitting range 1212. By setting the first light-shielding component 131, the light-leaking part in the actual light-emitting range 1212 of the laser emission module 120 is blocked, forming an effective processing range 1213. Moving the laser beam of the laser emission module 120 on the processing surface of the flat wire 200 can ensure that the sides of the flat wire can be fully cleaned while also solving the safety hazard problem caused by the light leakage of the laser beam.
[0059] Specifically, the first light-shielding component includes a first light-shielding sheet 1311 and a second light-shielding sheet 1312, and the first light-shielding sheet 1311 and the second light-shielding sheet 1312 in the same component are respectively located on opposite sides of the flat wire 200. The first light-shielding sheet 1311 and the second light-shielding sheet 1312 are movably arranged on the flat wire carrier 110, and both the first light-shielding sheet 1311 and the second light-shielding sheet 1312 can move along the direction close to or away from the central axis 1211 of the original light-emitting range 121.
[0060] Among them, the first light-shielding sheet 1311 is arranged between the flat wire 200 and the current laser emission module 120. The first light-shielding sheet 1311 blocks part of the laser, so that the laser irradiates part of the area of the first side surface 210. As Figure 1 shown, relative to the left laser emission module 120, the flat wire 200 is located within the actual light-emitting range 1212, and the laser beam will leak out between the right edge of the first side surface 210 of the flat wire 200 and the lower edge of the actual light-emitting range 1212. At this time, adjust the position of the first light-shielding sheet 1311 along the direction away from the central axis 1211 of the current laser emission module 120, and use the first light-shielding sheet 1311 to block the laser beam from irradiating the right edge of the first side surface 210 of the flat wire 200.
[0061] During the adjustment process, use the indicating light in the laser to observe the position of the laser path. The indicating light forms a visible irradiation point on the surface of the flat wire 200 or the second light-shielding sheet 1312. Considering the deviation between the indicating light and the actual light during the laser processing, in order to better ensure that the laser beam does not leak from the right edge of the first side surface 210, when the irradiation point moves from the second side surface 220 to the first side surface 210, by adjusting the position of the first light-shielding sheet 1311, the position of the irradiation point does not exceed the midline position of the first side surface 210. The optimal adjustment position of the first light-shielding sheet 1311 makes the indicating light irradiate the middle position of the first side surface 210.
[0062] By making the irradiation point not exceed the midline position of the first side surface 210, the lower edge of the second side surface 220 can be fully stripped of paint, and the laser can also be prevented from irradiating the opposite laser emission module 120, thus avoiding the problem of cross shooting. Whether the actual light during the laser processing deviates to the left or right relative to the indicating light, the left half or the right half of the first side surface 210 can be used to block the laser beam, thereby reducing the light leakage problem of the laser at the lower edge of the flat wire 200.
[0063] Considering the deviation between the indicating light and the actual light during the laser processing, in order to enable the upper edge of the second side surface 220 to be laser cleaned, the indicating light cannot be adjusted only to the edge position of the upper edge of the second side surface 220, but to the space above the upper edge of the second side surface 220, so as to provide sufficient laser scanning space for the upper edge of the second side surface 220, so that there is an actual laser beam to clean the upper edge of the second side surface 220. Therefore, light leakage will occur at the position of the upper edge of the second side surface 220, and there is a safety hazard of the laser emission module shooting at each other.
[0064] To eliminate the above safety hazard, the second light shielding sheet 1312 is arranged on the side of the flat wire 200 away from the current laser emission module 120, and the second light shielding sheet 1312 blocks the light beyond the edge of the second side surface 220 away from the first side surface 210. As Figure 1 shown, the second light shielding sheet 1312 is used to block the laser light leaking out from the position of the upper edge of the second side surface 220. At this time, the position of the second light shielding sheet 1312 is adjusted along the direction of the central axis 1211 of the current laser emission module 120, so that when the laser beam just leaks out from the upper edge of the second side surface 220, the laser beam irradiates on the second light shielding sheet 1312.
[0065] Specifically, when the indicating light leaks out from the upper edge of the second side surface 220, the indicating light irradiates on the second light shielding sheet 1312 and forms an irradiation point. There is still a distance between the irradiation point on the second light shielding sheet 1312 and one end of the second light shielding sheet 1312 close to the central axis 1211 of the current laser emission module 120, so as to ensure sufficient shielding margin. It is worth mentioning that even if multiple side surfaces of the flat wire 200 are cleaned, resulting in the reduction of the size of the flat wire 200 and the increase of the laser beam leaking out from the upper edge of the second side surface 220, the sufficient shielding margin in the second light shielding sheet 1312 can also be used for shielding at this time, reducing the safety hazard caused by laser light leakage.
[0066] It should be noted that, as Figure 1 shown, when the second light shielding sheet 1312 on the right side is used to block the laser beam of the laser emission module 120 on the left side, the second light shielding sheet 1312 still has room to continue to move downward. However, in the case of multi-surface cleaning, for example, the right side of the flat wire 200 also needs laser cleaning, the lower end of the second light shielding sheet 1312 on the right side cannot enter the actual light emitting range 1212 of the laser emission module 120 on the right side. If it exceeds, it may cause the problem that the laser cleaning of the right side surface of the flat wire 200 by the laser emission module 120 on the right side is incomplete, affecting the paint stripping effect on the right side of the flat wire 200.
[0067] In some embodiments, as Figure 1As shown, there are four laser emission modules 120 and four first light-shielding components. The four laser emission modules 120 are arranged around the circumference of the flat wire carrier 110, so that each laser emission module 120 is used to process one side of the flat wire 200, improving the paint stripping efficiency and the paint stripping effect.
[0068] As Figure 1 and Figure 3 shown, the four laser emission modules 120 are arranged in pairs opposite to each other. The two sets of laser emission modules 120 arranged opposite to each other are installed horizontally and vertically. That is, the central axes 1211 of the original light-emitting ranges 121 of the two laser emission modules 120 arranged opposite to each other on the left and right coincide, and the central axes 1211 of the original light-emitting ranges 121 of the two laser emission modules 120 arranged opposite to each other on the top and bottom coincide.
[0069] The flat wire 200 is located on the same side of the central axes of the two laser emission modules 120 in the same group and in the intersecting area of the actual light-emitting ranges 1212 of the two laser emission modules 120, avoiding the two actual light-emitting ranges 1212 facing each other and reducing the risk of direct shooting. For example: the flat wire 200 is arranged above the central axes of the two horizontally installed laser emission modules 120 and to the left of the central axes 1211 of the two vertically installed laser emission modules 120.
[0070] In some embodiments, the processing channel 112 is formed by the spaced arrangement of the first light-shielding sheet 1311 corresponding to a certain laser emission module 120 and the second light-shielding sheet 1312 corresponding to another laser emission module 120 opposite to a certain laser emission module 120. By reasonably arranging the positions of the two relatively arranged first light-shielding components, the structure of the flat wire carrier 110 is simplified, and the structure of the flat wire carrier 110 is made more compact.
[0071] In some embodiments, a dust suction joint 113 is further provided on the housing 111, and the dust suction joint 113 is communicated with the housing 111. By providing the dust suction joint 113 on the housing 111, it is convenient to quickly remove the dust generated during the paint stripping process, avoid the adverse effects of the dust on the laser beam, and improve the paint stripping effect.
[0072] As Figure 1 and Figure 2 shown, in this embodiment, the housing 111 is a regular octagon, and the side wall where the dust suction joint 113 is located can also be used to block the leaking laser beam, further realizing the light-blocking function.
[0073] In some embodiments, on the focal plane of the laser emission module 120, there is a spacing L1 between the laser beam within the actual light-emitting range 1212 of the laser emission module 120 and the central axis 1211 of the original light-emitting range 121 of the laser emission module 120, satisfying: 20 mm ≤ L1 ≤ 35 mm, or 40 mm ≤ L1 ≤ 60 mm.
[0074] Wherein, the focal plane refers to the plane perpendicular to the central axis 1211 of the original light-emitting range 121 of the laser emission module 120 at the focal length value position of the field lens. When cleaning the side surface of the flat wire 200, by adjusting the spatial position of each laser emission module 120, the side surface of the flat wire 200 facing the laser emission module 120 is located within the focal plane of the laser emission module 120.
[0075] Specifically, as Figure 1 shown, taking the left laser emission module 120 as an example, the focal length of the field lens used in the laser emission module 120 is 160 mm, and the left side surface of the flat wire 200 is located within the focal plane of the left laser emission module 120. In this focal plane, the spacing L1 between the lower edge of the actual light-emitting range 1212 of the left laser emission module 120 and the central axis 1211 of the original light-emitting range 121 is 20 mm, and the spacing L1 between the upper edge of the actual light-emitting range 1212 of the left laser emission module 120 and the central axis 1211 of the original light-emitting range 121 is 35 mm. That is, within the focal plane, relative to the central axis of the original light-emitting range 121, the overall offset of the actual light-emitting range 1212 is 20 mm to 35 mm. When the focal length of the field lens used in the laser emission module 120 is 254 mm, the overall offset of the actual light-emitting range 1212 is 40 mm to 60 mm. Of course, when using field lenses with other focal lengths, the overall offset of the actual light-emitting range 1212 will also change accordingly.
[0076] As Figure 3 shown, in some embodiments, the flat wire paint stripping device further includes at least one second light-shielding component 140. The second light-shielding component 140 is disposed between the flat wire carrier 110 and the laser emission module 120. One second light-shielding component 140 is connected to one laser emission module 120, and the second light-shielding component 140 is used to block more than half of the original light-emitting range 121 of the laser emission module 120.
[0077] The actual light-emitting range 1212 of the laser emission module 120 can be achieved by controlling the galvanometer in the laser emission module 120 to offset the laser beam, or by using the second light-shielding component 140 to partially block the original light-emitting range 121 to directly form the actual light-emitting range 1212.
[0078] The second light-shielding component 140 includes a third light-shielding sheet 141 and a fourth light-shielding sheet 142. The third light-shielding sheet 141 and the fourth light-shielding sheet 142 are arranged at intervals, and the third light-shielding sheet 141 and the fourth light-shielding sheet 142 can approach or separate from each other, so as to adjust the distance between the third light-shielding sheet 141 and the fourth light-shielding sheet 142. By adjusting the positions and spacing of the third light-shielding sheet 141 and the fourth light-shielding sheet 142, the laser beam passing through between the third light-shielding sheet 141 and the fourth light-shielding sheet is just located within the actual light-emitting range 1212, and the galvanometer can be controlled without separate control, realizing physical light shielding and laser beam offset.
[0079] As Figure 4 shown, an embodiment of the present application further provides a method for stripping paint from flat wires, including:
[0080] S10, threading the flat wire 200 through the flat wire carrier 110. The flat wire carrier 110 is provided with a first light-shielding component corresponding to the laser emission module 120. The first light-shielding component includes a first light-shielding sheet 1311 and a second light-shielding sheet 1312, and controlling the laser emission module 120 to emit an indicating light beam.
[0081] S20, selecting any one of the laser emission modules 120, and adjusting the position of the first light-shielding sheet 1311 corresponding to the currently selected laser emission module 120, so that when the indicating light beam moves from the second side 220 of the flat wire 200 to the first side 210, part of the area where the indicating light beam irradiates the first side 210 is blocked.
[0082] Among them, blocking part of the area where the indicating light beam irradiates the first side 210 means that: during the movement of the irradiation point from the second side 220 to the first side 210, the position of the irradiation point does not exceed the central position of the first side 210.
[0083] S30, adjusting the position of the second light-shielding member corresponding to the currently selected laser emission module 120 to block the light beam leaking out when the indicating light beam exceeds the edge of the second side 220 far from the first side 210.
[0084] S40, selecting the next laser emission module 120, and repeating the above process until the first light-shielding components corresponding to all the laser emission modules 120 are adjusted.
[0085] S50, controlling the laser emission module 120 to emit a laser processing beam according to the set laser parameters.
[0086] It should be noted that the order of steps S10 to S50 can be adjusted as needed and there is no special limitation.
[0087] Exemplarily, please refer to Figure 1, the adjustment process of the first light-shielding sheet 1311 and the second light-shielding sheet 1312 of the left laser emission module 120 is as follows:
[0088] First, move the first light-shielding sheet 1311 until the extension line of the connection line between the center point of the laser emission module 120 and the upper left corner of the first light-shielding sheet 1311 intersects the first side surface 210 of the flat wire 200, and the intersection position is between the left edge and the midline of the first side surface 210, then the adjustment of the first light-shielding sheet 1311 is completed.
[0089] Then, move the second light-shielding sheet 1312 on the right side of the flat wire 200 until the extension line of the connection line between the center point of the laser emission module 120 and the upper left corner of the flat wire 200 intersects the left surface of the first light-shielding sheet 1311, and there is a spacing between the intersection position and the lower edge of the first light-shielding sheet 1311, then the adjustment of the second light-shielding sheet 1312 is completed.
[0090] In some embodiments, in the step of selecting any one of the laser emission modules 120 and adjusting the position of the first light-shielding sheet 1311 corresponding to the currently selected laser emission module 120, it further includes:
[0091] Step S31, determine that there is still a second light-shielding sheet 1312 on the same side between the currently selected laser emission module 120 and the flat wire 200, where the second light-shielding sheet 1312 on the same side is the second light-shielding sheet 1312 of another laser emission module 120 opposite to the currently selected laser emission module 120.
[0092] In some embodiments, if only three surfaces of the flat wire 200 need to be stripped of paint, for example, Figure 1 stripping the paint from the left, right, and lower three surfaces of the flat wire 200 in the middle, then the laser emission module 120 may not be provided at the upper side position of the flat wire 200. Correspondingly, the second light-shielding sheet 1312 at the lower side of the flat wire 200 may not exist, while the second light-shielding sheets 1312 at the left, right, and upper sides must exist.
[0093] Step S32, adjust the position of the second light-shielding sheet 1312 on the same side so that the second light-shielding sheet 1312 on the same side is outside the actual light-emitting range 1212 of the currently selected laser emission module 120.
[0094] In this way, it can be avoided that the second light-shielding sheet 1312 on the same side blocks the actual light-emitting range 1212 of the laser emission module 120, ensuring that the side surfaces of the flat wire 200 can be fully cleaned and processed.
