Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of automobile instrument panel manufacturing, especially relates to a laser weakening equipment for automobile instrument panel. BACKGROUND

[0002] With the continuous development of automobile technology, the requirement of such a part as instrument panel which integrates safety, functionality, comfort and decoration is higher and higher, especially its safety. One of them is a seamless airbag instrument panel which processes a safety airbag line on the instrument panel body and is adopted in many new models. In the future, the application of such seamless safety airbag instrument panel will be more and more extensive, therefore, its processing technology will become the key technology which must be mastered by instrument panel professional manufacturers.

[0003] There are many kinds of processing technology of seamless safety airbag line, such as injection molding, hot knife, metal or ultrasonic cold knife, cold milling and laser, etc. Among them, laser weakening is just rising in recent years, and laser weakening is divided into two kinds, one is instrument panel skeleton weakening and the other is instrument panel skin weakening. Two different weakening methods need to use different lasers, so when manufacturing automobile instrument panel, weakening needs to be carried out through two stations, thereby increasing the number of stations of automobile instrument panel production line and increasing the space occupied by automobile instrument panel production line. SUMMARY

[0004] In view of the above problems, the embodiment of the present application provides a laser weakening equipment for automobile instrument panel, which can weaken the instrument panel skeleton and the instrument panel skin of the automobile instrument panel at the same station, thereby reducing the number of stations of the automobile instrument panel production line and reducing the space occupied by the automobile instrument panel production line.

[0005] The embodiment of the present application provides a laser weakening equipment for automobile instrument panel, which comprises a shell, a first laser emitter, a second laser emitter and a reflection mechanism. The shell has a first wall and a second wall oppositely arranged in a first direction, the first wall is provided with a first light inlet hole, and the second wall is provided with a first light outlet hole corresponding to the first light inlet hole; the first laser emitter is used to provide a first laser beam extending along the first direction into the shell through the first light inlet hole; the second laser emitter is arranged in the shell and is used to provide a second laser beam extending along a second direction into the shell, the power of the first laser emitter and the power of the second laser emitter are not equal, and the first direction is perpendicular to the second direction; the reflection mechanism is arranged in the shell and has a first position and a second position, the reflection mechanism is configured to: when the reflection mechanism is in the first position, the reflection mechanism does not block the first light inlet hole; when the reflection mechanism is in the second position, the reflection mechanism blocks the first light inlet hole and reflects the second laser beam so that the second laser beam exits the shell from the first light outlet hole.

[0006] Specifically, taking the first laser emitter as a high-power laser emitter as an example, when the instrument panel skeleton needs to be weakened, and thus the automobile instrument panel laser weakening device needs to provide a higher energy laser, by locating the reflecting mechanism at the first position, the reflecting mechanism does not block the first light inlet hole, and thus the first laser beam emitted by the first laser can enter the shell from the first light inlet hole and exit the shell through the first light outlet hole for weakening the instrument panel skeleton.

[0007] When the instrument panel skin needs to be weakened, and thus the automobile instrument panel laser weakening device needs to provide a lower energy laser, by locating the reflecting mechanism at the second position, the reflecting mechanism blocks the first light inlet hole, and thus the first laser beam emitted by the first laser cannot enter the shell from the first light inlet hole, and the second laser beam is reflected by the reflecting mechanism so as to exit the shell from the first light outlet hole.

[0008] In the above technical solution, the first light outlet hole can emit laser beams of different energies, respectively, and thus the instrument panel skeleton and the instrument panel skin of the automobile instrument panel can be weakened, respectively, and the instrument panel skeleton weakening and the instrument panel skin weakening of the automobile instrument panel can be performed at the same station, thereby reducing the number of stations of the automobile instrument panel production line and reducing the space occupied by the automobile instrument panel production line.

[0009] In some embodiments, the reflecting mechanism includes a mirror and a mirror seat assembly. The mirror is provided with a reflecting surface; the mirror seat assembly is movably arranged in the shell, and the mirror is arranged on the mirror seat assembly. When the mirror seat assembly drives the mirror to be located at the second position, the plane in which the reflecting surface is located forms an angle of 45° with the second direction, and the plane in which the reflecting surface is located forms an angle of 45° with the first direction.

[0010] In the above technical solution, when the mirror is located at the second position, the plane in which the reflecting surface is located forms an angle of 45° with the second direction, and the plane in which the reflecting surface is located forms an angle of 45° with the first direction, so that the second laser beam can be emitted from the first light outlet hole along the first direction after being reflected by the reflecting surface, and thus can be used for weakening the automobile instrument panel.

[0011] In some embodiments, the mirror seat assembly is adjustably arranged in the shell along the second direction.

[0012] In the technical solution, the mirror seat assembly is adjustably arranged in the shell along the second direction. On one hand, the angle between the plane of the reflecting surface and the first direction and the second direction is not changed during the movement of the mirror seat assembly. On the other hand, the movement of the reflecting mirror along the second direction enables the second laser beam to be reflected by the reflecting surface at all times, thereby reducing the risk of damage to the reflecting mirror caused by the irradiation of the second laser beam on the non-reflecting surface relative to the case where the mirror seat assembly is configured to drive the reflecting mirror to rotate.

[0013] In some embodiments, the reflecting mechanism further comprises a light shield, the light shield being sleeved outside the reflecting mirror; when the reflecting mechanism is located at the first position, the light shield blocks the first light inlet hole; the light shield has a second light inlet hole and a second light outlet hole, when the reflecting mechanism is located at the second position, the second light inlet hole is configured to allow the second laser beam to enter the light shield, the second light outlet hole is configured to allow the second laser beam to exit the light shield, and the second light outlet hole is configured to be arranged correspondingly to the first light outlet hole.

[0014] In the technical solution, by arranging the light shield, the risk of damage to the reflecting mirror caused by the irradiation of the first laser beam on the non-reflecting surface is reduced relative to the case where the non-reflecting surface of the reflecting mirror blocks the first laser beam.

[0015] In some embodiments, the power of the first laser emitter is greater than the power of the second laser emitter.

[0016] In the technical solution, since a high-power laser emitter usually requires a larger power supply, a more powerful cooling system and a more robust structure to support high-energy output, the volume of the high-power laser emitter is usually larger than that of the low-power laser emitter. By setting the power of the first laser emitter to be greater than the power of the second laser emitter and arranging the first laser emitter outside the shell, the assembly of the first laser emitter is facilitated.

[0017] In some embodiments, the laser weakening device for the automobile instrument panel further comprises a driving member arranged in the shell, the driving member being configured to drive the reflecting mechanism to switch between the first position and the second position.

[0018] In the technical solution, the reflecting mechanism is driven by the driving member to switch between the first position and the second position, so that the first light outlet hole emits the first laser beam and the second laser beam, respectively. This is simpler in structure and easier to implement relative to the case where the adjustment is performed by hand.

[0019] In some embodiments, the housing comprises a shell and an end cover. The shell has the first wall and the second wall oppositely arranged in the first direction, and has a first opening arranged on one side in a third direction, the first direction, the second direction and the third direction being perpendicular to each other; the end cover is rotatably arranged on the shell and is used to open and close the first opening.

[0020] In the above technical solution, by arranging the housing as a split structure of a shell having a first opening on one side and an end cover used to open and close the shell, the installation of the second laser emitter and the reflecting mechanism through the first opening is facilitated.

[0021] In some embodiments, the shell has a third wall away from the first opening in the third direction, the third wall supporting the reflecting mechanism along the third direction; the laser weakening device for the automobile instrument panel further comprises an adjusting support, the second laser emitter being connected with the third wall through the adjusting support, the adjusting support being used to adjust the distance between the second laser emitter and the inner surface of the third wall in the third direction.

[0022] In some embodiments, the first wall is provided with a hollowed-out area; the end cover comprises a body part used to open and close the first opening and an extension part connected with the body part, the extension part closing the hollowed-out area when the body part closes the first opening, and the adjusting support being exposed to the outside through the hollowed-out area when the body part opens the first opening.

[0023] In the above technical solution, by exposing the adjusting support to the outside through the hollowed-out area when the body part opens the first opening, the operator can adjust the adjusting support through the hollowed-out area to adjust the second laser emitter.

[0024] In some embodiments, the laser weakening device for the automobile instrument panel further comprises a light pipe, the light pipe extending along the first direction, one end of the light pipe being arranged on the first wall and being in communication with the first light inlet hole, and the other end of the light pipe being in communication with the first laser emitter.

[0025] In the above technical solution, by connecting the first laser emitter and the first light inlet hole through the light pipe, the risk of dust entering the housing through the first light inlet hole and falling on the reflecting mechanism to cause the reflecting mechanism to fail to reflect is reduced.

[0034] With the continuous development of automobile technology, the requirements for the instrument panel, which integrates safety, functionality, comfort and decoration, are getting higher and higher, especially its safety. One of them is a seamless airbag instrument panel with a safety airbag line processed on the instrument panel body, which has been adopted in many new models. In the future, the application of such seamless safety airbag instrument panel will be more and more extensive, and therefore its processing technology will become a key technology that instrument panel professional manufacturers must master.

[0035] There are many kinds of processing technology for seamless safety airbag line, such as injection molding, hot knife, metal or ultrasonic cold knife, cold milling and laser, etc. Among them, laser weakening has just emerged in recent years, and laser weakening is divided into two kinds, one is instrument panel skeleton weakening and the other is instrument panel skin weakening. Two different weakening methods need to use different lasers, so when manufacturing automobile instrument panel, it needs to go through two stations for weakening, thereby increasing the number of stations of automobile instrument panel production line and the space occupied by automobile instrument panel production line.

[0036] In order to solve the above technical problems, with reference to Figs. 1-3 The embodiment of the present application provides a kind of laser weakening equipment 100 for automobile instrument panel, including shell 10, first laser emitter, second laser emitter 20 and reflection mechanism 30. Shell 10 has oppositely arranged first wall 111 and second wall 112 in first direction X, first wall 111 is provided with first light inlet hole 1111, and second wall 112 is provided with first light outlet hole 1121 corresponding to first light inlet hole 1111;First laser emitter is used to provide first laser beam 401 extending along first direction X into shell 10 by first light inlet hole 1111;Second laser emitter 20 is arranged in shell 10, and is used to provide second laser beam 201 extending along second direction Y into shell 10, the power of first laser emitter and the power of second laser emitter 20 are not equal, and first direction X is perpendicular to second direction Y;Reflection mechanism 30 is arranged in shell 10 and has first position and second position, and reflection mechanism 30 is configured to: when being in first position, reflection mechanism 30 does not shield first light inlet hole 1111;When being in second position, reflection mechanism 30 shields first light inlet hole 1111, and reflects second laser beam 201 so that second laser beam 201 exits from first light outlet hole 1121 out of shell 10.

[0037] It can be understood that shell 10 can be made of metal material such as copper, aluminum or stainless steel, and shell 10 can also be made of ceramic material such as alumina or silicon oxide, so that the shell 11 can absorb or shield first laser beam 401 and second laser beam 201.

[0038] It can be understood that the laser beam provided by the one of the first laser emitter and the second laser emitter 20 with greater power can be used for instrument panel skeleton weakening, and the laser beam provided by the one with smaller power can be used for instrument panel skin weakening.

[0039] Exemplarily, the first laser emitter and the second laser emitter 20 can be a laser emitter providing a laser power output of 100 watts and a laser emitter providing a laser power output of up to 2000 watts, respectively.

[0040] The first direction X can be parallel to the width direction of the shell 10, the second direction Y can be parallel to the length direction of the shell 10, and the third direction Z can be parallel to the height direction of the shell 10.

[0041] The "shielding the first light inlet hole 1111" can be understood as that part of the reflection mechanism 30 is located between the first light inlet hole 1111 and the first light outlet hole 1121 so that the first laser beam 401 cannot pass out of the first light outlet hole 1121 along the first direction X.

[0042] Specifically, taking the first laser emitter as a high-power laser emitter as an example, when it is necessary to weaken the instrument panel skeleton and thus it is necessary for the laser weakening device 100 for the automotive instrument panel to provide a laser with higher energy, by locating the reflection mechanism 30 at the first position, the reflection mechanism 30 does not block the first light inlet hole 1111, and thus the first laser beam 401 emitted by the first laser emitter can enter the shell 10 from the first light inlet hole 1111 and exit the shell 10 through the first light outlet hole 1121, for weakening the instrument panel skeleton.

[0043] When it is necessary to weaken the instrument panel skin and thus it is necessary for the laser weakening device 100 for the automotive instrument panel to provide a laser with lower energy, by locating the reflection mechanism 30 at the second position, the reflection mechanism 30 blocks the first light inlet hole 1111, and thus the first laser beam 401 emitted by the first laser emitter cannot enter the shell 10 from the first light inlet hole 1111, and the second laser beam 201 is reflected by the reflection mechanism 30 so as to exit the shell 10 from the first light outlet hole 1121.

[0044] In the technical solution, the first light outlet hole 1121 can emit laser beams with different energies respectively by the above design, and thus it is convenient to weaken the instrument panel skeleton and the instrument panel skin of the automotive instrument panel respectively, and the instrument panel skeleton weakening and the instrument panel skin weakening of the automotive instrument panel can be performed at the same station, thereby reducing the number of stations of the automotive instrument panel production line and reducing the space occupied by the automotive instrument panel production line.

[0045] According to some embodiments of the present application, the reflecting mechanism 30 comprises a mirror 31 and a mirror seat assembly 32. The mirror 31 is provided with a reflecting surface; the mirror seat assembly 32 is movably arranged in the housing 10, and the mirror 31 is arranged on the mirror seat assembly 32. When the mirror seat assembly 32 drives the mirror 31 to the second position, the plane in which the reflecting surface is located forms an angle of 45° with the second direction Y, and the plane in which the reflecting surface is located forms an angle of 45° with the first direction X.

[0046] In some embodiments, the mirror seat assembly 32 can be a rotary table which can be used to drive the mirror 31 to rotate along a first axis which can be parallel to the third direction Z. In the first position, the reflecting surface of the mirror 31 is parallel to the first direction X, and the mirror 31 is located on one side of the first light inlet hole 1111 in the second direction Y. In the second position, the plane in which the reflecting surface is located forms an angle of 45° with the second direction Y, and the plane in which the reflecting surface is located forms an angle of 45° with the first direction X, and the non-reflecting surface of the mirror 31 blocks the first light inlet hole 1111.

[0047] In the technical solution, when the mirror 31 is in the second position, the plane in which the reflecting surface is located forms an angle of 45° with the second direction Y, and the plane in which the reflecting surface is located forms an angle of 45° with the first direction X, so that the second laser beam 201 can be reflected by the reflecting surface and then emitted along the first direction X from the first light outlet hole 1121, thereby facilitating weakening of the automobile instrument panel.

[0048] According to some embodiments of the present application, the mirror seat assembly 32 is adjustably arranged in the housing 10 along the second direction Y.

[0049] In some embodiments, the mirror seat assembly 32 can comprise a sliding table and a guide rail. The guide rail is arranged in the housing 10 and extends along the second direction Y. The sliding table is slidingly arranged on the guide rail, and the mirror 31 is arranged on the sliding table.

[0050] In the technical solution, the mirror seat assembly 32 is adjustably arranged in the housing 10 along the second direction Y. On the one hand, the angle between the plane in which the reflecting surface is located and the first direction X and the second direction Y will not change during the movement of the mirror seat assembly 32. On the other hand, the mirror 31 moves along the second direction Y, and the second laser beam 201 can be reflected by the reflecting surface at all times, thereby reducing the risk of damage to the mirror 31 caused by the second laser beam 201 being irradiated on the non-reflecting surface relative to the case where the mirror seat assembly 32 is configured to drive the mirror 31 to rotate.

[0051] According to some embodiments of the present application, the reflecting mechanism 30 further comprises a light shield 33, the light shield 33 is sleeved outside the reflecting mirror 31; when the reflecting mechanism 30 is located at the first position, the light shield 33 shields the first light inlet hole 1111; the light shield 33 has a second light inlet hole 331 and a second light outlet hole 332, when the reflecting mechanism 30 is located at the second position, the second light inlet hole 331 is configured to allow the second laser beam 201 to enter the light shield 33, the second light outlet hole 332 is configured to allow the second laser beam 201 to exit the light shield 33, and the second light outlet hole 332 is configured to be arranged corresponding to the first light outlet hole 1121.

[0052] It can be understood that the light shield 33 can be made of a metal material such as copper, aluminum or stainless steel, and the shell 10 can also be made of a ceramic material such as aluminum oxide or silicon oxide, so that the shell 11 can absorb or shield the first laser beam 401 and the second laser beam 201.

[0053] In the technical solution, by arranging the light shield 33, compared with the scheme of shielding the first laser beam 401 on the non-reflective surface of the reflecting mirror, the risk of damage to the reflecting mirror 31 caused by the first laser beam 401 irradiating on the non-reflective surface is reduced.

[0054] According to some embodiments of the present application, the power of the first laser emitter is greater than the power of the second laser emitter 20.

[0055] Exemplarily, the first laser emitter can be a DC020 model laser emitter of ROFIN, and the second laser emitter 20 can be a Cx-10L model laser emitter of Diamond.

[0056] In the technical solution, since a high-power laser emitter usually needs a larger power supply, a more powerful cooling system and a more solid structure to support high energy output, the volume of the high-power laser emitter is usually larger than that of the low-power laser emitter. Therefore, by setting the power of the first laser emitter to be greater than the power of the second laser emitter 20 and arranging the first laser emitter outside the shell 10, the assembly of the first laser emitter is facilitated.

[0059] In the technical solution, the driving member drives the reflecting mechanism 30 to switch between the first position and the second position, so that the first light outlet respectively emits the first laser beam 401 and the second laser beam 201, which is simpler in structure and easier to realize compared with adjustment by hand.

[0060] According to some embodiments of the present application, the shell 10 includes a housing 11 and an end cover 12.
