The technical solutions disclosed in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

Example 1;

referring to fig. 1 to 5, an embodiment of the present application discloses a paint removing jig for fixing a workpiece 500 to perform a paint removing process on the workpiece 500. Specifically, the workpiece 500 has a paint removal surface, the paint removal surface is coated with an outer paint, and the outer paint on the paint removal surface of the workpiece 500 can be subjected to paint removal treatment by the laser paint removal device.

The paint removal jig comprises a base 100, wherein the base 100 is a basic component of the paint removal jig, and the base 100 can provide a mounting base for at least part of other components of the paint removal jig and a workpiece 500. The base 100 is provided with a first positioning groove 210, and the first positioning groove 210 can accommodate the workpiece 500, so that the workpiece 500 can be fixed on the base 100. The first positioning groove 210 serves to limit and fix the workpiece 500, so that the workpiece 500 is stable.

Specifically, the base 100 may be a plate-shaped structure, and the base 100 has a first plate 140 and a second plate 150 opposite to each other, wherein the first plate 140 of the base 100 contacts with the supporting plane, so that the contact area between the base 100 and the supporting plane is relatively large, and the base 100 can be stably located on the supporting plane. Of course, the support plane and the first plate surface 140 may also be provided with corresponding fixing structures, so that the base 100 has better stability when located on the support plane, and the application is not limited thereto. The first positioning groove 210 may be disposed on the second plate 150, and the larger area of the second plate enables the groove-type configuration and the position configuration of the first positioning groove 210 to be more free.

The laser paint removing device can be arranged opposite to the second plate surface 150 of the base 100, when the base 100 is arranged on a horizontal plane, namely the laser paint removing device is arranged above the base 100, the laser paint removing device can emit laser, and the laser irradiates the paint removing surface of the workpiece 500 in the first positioning groove 210, so that the process of removing paint from the paint removing surface of the workpiece 500 is completed.

The paint-release surface of the workpiece 500 is a curved surface, a sloped surface, or a combination of a partial curved surface and a partial sloped surface, which results in a height difference between various portions of the paint-release surface. In the case where the workpiece 500 is disposed in the first positioning groove 210, the workpiece 500 is disposed obliquely with respect to the horizontal plane, which can reduce the height of the paint-removed surface of the workpiece 500. The laser emitted by the laser paint removing device has a focal length, and the energy at the focal point of the laser is the largest, so that the paint removing effect of the workpiece 500 is the best when the focal point of the laser is positioned on the paint removing surface of the workpiece 500, and the inclined arrangement of the paint removing surface of the workpiece 500 can reduce the height difference of each part on the paint removing surface.

Referring to fig. 6 to 8, in detail, when the paint removing surface of the workpiece 500 is a curved surface having a vertex 510 located at the center of the curved surface, and a first side region 520 and a second side region 530 located at both sides of the vertex 510, the height of the vertex 510 of the curved surface is higher than the height of the first side region 520 and the second side region 530 located at both sides of the curved surface in a case where the workpiece 500 is vertically placed on a horizontal plane. When the workpiece 500 is obliquely disposed in the first positioning groove 210, the oblique workpiece 500 is deflected with respect to the workpiece 500 vertically placed on a horizontal plane, and the workpiece 500 can be rotated with respect to the center of the arc surface. In the case where the workpiece 500 is rotated in the counterclockwise direction, the tilted workpiece 500 causes the height of the apex 510 of the arc surface to be lowered and the height of the first side region 520 to be raised, so that the difference in height between the first side region 520 and the apex 510 is lowered, thereby enabling the first side region 520 to be depainted without excessively changing the focus of the laser depainting apparatus.

In the case where the workpiece 500 is rotated in the clockwise direction, the tilted workpiece 500 causes the height of the apex 510 of the arc to be lowered and the height of the second side region 530 to be raised, so that the difference in height between the second side region 530 and the apex 510 is lowered, thereby allowing the second side region 530 to be depainted without changing the focal point of the laser depainting apparatus too much.

Referring to fig. 9 and 10, in the case that the paint removing surface of the workpiece 500 is a slope and the workpiece 500 is in a natural state, the workpiece 500 has a first point with the highest relative height and a second point with the lowest relative height, and the first point and the second point of the paint removing surface are in an inclined transition. In the case where the workpiece 500 is disposed in the first positioning groove 210 and inclined from the horizontal plane, the paint removing surface, which is an inclined surface, may be inclined accordingly such that the difference in height between the first point and the second point of the inclined surface is reduced.

Of course, the workpiece 500 may also be tilted until the bevel is parallel to the horizontal plane, such that the height difference between the first point 540 and the second point 550 of the bevel is zero, and correspondingly, the height difference between the portions of the bevel is zero. Under the condition of not changing the height of the laser paint removing device, the focus of the laser emitted by the laser paint removing device can be always positioned on the paint removing surface, so that the paint removing effect of each part of the paint removing surface is consistent. Thereby greatly simplifying the paint removing process.

In the actual paint removing process, the energy of the laser emitted by the laser paint removing device at the focus is strongest, and correspondingly, the energy of the laser close to the focus is also stronger, so that when the height difference of each part of the paint removing surface of the workpiece 500 is smaller, the paint removing can be performed on each part of the paint removing surface under the condition of not changing the focus of the laser, and thus the focus of the laser does not need to be adjusted in the paint removing process, and the paint removing efficiency of a paint removing part is greatly improved.

In the paint removing jig disclosed in the embodiment of the application, the workpiece 500 can be arranged in the first positioning groove 210, so that the workpiece 500 can be fixed, and when the workpiece 500 is arranged in the first positioning groove 210, the workpiece 500 is inclined relative to the horizontal plane, so that the paint removing surface of the workpiece 500 is inclined accordingly. After the paint removing surface of the cambered surface or the inclined surface is inclined, the height difference of each part on the paint removing surface can be reduced, so that the adjustment range of the laser focus of the laser paint removing device is reduced, and the paint removing efficiency of the workpiece 500 is improved.

In some embodiments, in order to make it easier to strip the work piece 500 disposed in the first positioning groove 210, in the case where the work piece 500 is disposed in the first positioning groove 210, the strip surface of the work piece 500 is located outside the first positioning groove 210. Specifically, the groove depth that can set up first constant head tank 210 is less than the size of work piece 500, make partial work piece 500 be in first constant head tank 210 like this, reach the purpose of fixed work piece 500, partial work piece 500 is outside first constant head tank 210, make and take off the lacquer painting and be located outside first constant head tank 210, can reduce the interval of work piece 500 and laser paint removal device like this, and simultaneously, also can prevent that the laser that laser paint removal device launched from shining the inner wall of first constant head tank 210 and damaging first constant head tank 210, play the purpose of protection first constant head tank 210.

It should also be noted that when the paint removing surface of the workpiece 500 is located outside the first positioning groove 210, the paint removing condition of the workpiece 500 can be conveniently observed during the paint removing process of the workpiece 500, so that an operator can conveniently adjust the laser paint removing device according to the paint removing condition of the workpiece 500, and the laser paint removing precision is improved.

Of course, the first positioning slot 210 may also be configured to completely receive the workpiece 500 therein, and the paint removing surface faces the notch of the first positioning slot 210, so that the first positioning slot 210 has a better fixing effect on the workpiece 500.

In some embodiments, in order to stabilize the workpiece 500 when disposed in the first positioning groove 210, the groove shape of the first positioning groove 210 may be configured to match the outer shape of the workpiece 500. Specifically, when at least a part of the workpiece 500 is disposed in the first positioning groove 210, a gap between an outer wall of the part of the workpiece 500 located in the first positioning groove 210 and an inner wall of the first positioning groove 210 is reduced, so that the workpiece 500 is prevented from shaking in the first positioning groove 210. Therefore, when the laser paint removing device removes paint and paint from the workpiece 500, the workpiece 500 is kept stable, and the laser paint removing precision is improved and higher.

In some embodiments, in order to make the paint removal efficiency of the workpieces 500 higher, the base 100 may further include a second positioning groove 310, both the first positioning groove 210 and the second positioning groove 310 may receive the workpieces 500, and a plurality of workpieces 500 may be respectively fixed in the first positioning groove 210 and the second positioning groove 310, such that the plurality of workpieces 500 may be subjected to the paint removal process simultaneously.

The second positioning groove 310 and the first positioning groove 210 are symmetrically arranged relative to the preset plane 160, wherein the preset plane 160 is vertically arranged on the base 100, the first positioning groove 210 and the second positioning groove 310 are both arranged on the plate surface on one side of the base 100, and the preset plane 160 is vertically arranged on the plate surface. Thus, the first and second positioning grooves 210 and 310 have similar groove types, except that the openings thereof are oriented in different directions, and accordingly, the workpiece 500 placed in the first positioning groove 210 and the workpiece 500 placed in the second positioning groove 310 are inclined in different directions.

Specifically, when the paint removing surface of the workpiece 500 is the arc surface, in a case where the workpiece 500 is placed in the first positioning groove 210, the apex 510 of the arc surface is disposed obliquely such that the first side region 520 is disposed opposite to the laser paint removing device, so that the laser paint removing device can perform the paint removing process on the first side region 520 of the workpiece 500. With the workpiece 500 placed in the second positioning groove 310, the apex 510 of the arc is obliquely disposed such that the second side region 530 is disposed opposite to the laser paint remover, so that the laser paint remover can perform a paint removing process on the second side region 530 of the workpiece 500.

When the paint removing process is performed, the workpiece 500 may be first placed in the first positioning groove 210, the first side region 520 may be subjected to paint removing treatment, after the paint removing of the first side region 520 is completed, the workpiece 500 may be placed in the second positioning groove 310, and the second side region 530 may be subjected to paint removing treatment, so that the paint removing surface of the workpiece 500 may be completely subjected to paint removing treatment.

In order to improve the paint removing efficiency, when a plurality of workpieces 500 need to be removed from the paint, two of the workpieces 500 can be respectively placed in the first positioning groove 210 and the second positioning groove 310, after the first side region 520 of one of the workpieces 500 is subjected to the paint removing treatment, the second side region 530 of the other workpiece 500 is also subjected to the paint removing treatment, and then the two workpieces 500 are exchanged in position, so that the two workpieces 500 can be simultaneously subjected to the paint removing treatment. This can multiply the paint removal efficiency of the workpiece 500.

Of course, a plurality of first positioning grooves 210 and a plurality of second positioning grooves 310 can be provided, so that a greater number of workpieces 500 can be processed at the same time, and the paint removing efficiency of the workpieces 500 can be further improved.

In some embodiments, the base 100 further defines a third positioning groove 410, and in a case that the workpiece 500 is disposed in the third positioning groove 410, the workpiece 500 is perpendicular to the base 100. Specifically, when the workpiece 500 is perpendicular to the horizontal plane, a portion of the paint-removed surface of the workpiece 500 is also parallel to the horizontal plane. Therefore, the paint removing surface and the laser paint removing device are arranged oppositely, and laser emitted by the laser paint removing device can be directly irradiated on the paint removing surface so as to remove outer paint on the paint removing surface. And the distance between the laser paint removing device and the paint removing surface can be kept unchanged all the time in the moving process of the laser paint removing device, so that the focal position of the laser emitted by the laser paint removing device is always positioned on the paint removing surface.

Particularly, when carrying out the paint removing process to the paint removing surface, can adjust the focus of the laser that the laser paint removing device launched to just being in on the paint removing surface, the laser that the laser paint removing device launched can remove along the paint removing surface, and at this in-process, the focus of laser is in on the paint removing surface all the time to make the paint removing effect of each part of paint removing surface unanimous, and then make the whole paint removing effect of work piece 500 better.

It should be noted that the third positioning groove 410 can also be used for storing the workpiece 500 to be stripped or the workpiece 500 after being stripped. When the paint removal jig of this application was applied to automatic production, equipment such as arm can shift waiting to paint removal work piece 500 that is located third constant head tank 410 to first constant head tank 210 and second constant head tank 310 in, can shift work piece 500 to third constant head tank 410 after the completion of the work piece 500 paint removal in, can improve the efficiency that work piece 500 took off the paint like this.

In some embodiments, the workpiece 500 may be configured to move on the base 100 in order to facilitate the work-piece 500 stripping process more efficiently. Therefore, each part of the paint removing surface of the workpiece 500 is opposite to the laser emitted by the laser paint removing device in a mode of moving the workpiece 500, so that the laser paint removing device does not need to be moved, and the paint removing process of the workpiece 500 is convenient and efficient.

Specifically, the paint removal jig of this application still includes first moving part 200, second moving part 300 and third moving part 400, and first positioning groove 210 sets up in first moving part 200, and first moving part 200 swing joint is in base 100, and first locating piece can move on the face of base 100 to the work piece 500 that makes to set up in first positioning groove 210 also can move on the face of base 100, can be relative with each part of the paint removal surface of work piece 500 and the laser that the laser paint removal device launched like this. Accordingly, the second positioning groove 310 can be opened in the second movable member 300, and the third positioning groove 410 can be opened in the third movable member 400, such that the workpiece 500 disposed in the second positioning groove 310 and the workpiece 500 disposed in the third positioning groove 410 can both move.

Specifically, when the work pieces 500 are subjected to the paint removing process, the work pieces 500 may be respectively placed in the first positioning groove 210 of the first movable member 200, the second positioning groove 310 of the second movable member 300, and the third positioning groove 410 of the third movable member 400, so that the paint removing process may be simultaneously performed on the work pieces 500, and the first movable member 200, the second movable member 300, and the third movable member 400 may be respectively moved such that each portion of the paint removing surfaces of the work pieces 500 may be subjected to paint removal.

In order to allow the first movable member 200, the second movable member 300, and the third movable member 400 to move on the base 100, the base 100 is provided with a first sliding groove 110, a second sliding groove 120, and a third sliding groove 130. The shape of the first movable member 200 is matched with the groove shape of the first sliding groove 110, so that at least a portion of the first movable member 200 is located in the first sliding groove 110, and the first sliding groove 110 can limit the first movable member 200, so that the first movable member 200 is stable in the moving process. Accordingly, the second movable member 300 has a profile that mates with the slot profile of the second runner 120 and the third movable member 400 has a profile that mates with the slot profile of the third runner 130.
