Abstract
Description
Technical Field
[0001] The present application relates to the field of laser processing, and in particular to a plastic housing facilitating laser processing. Background Art
[0002] Laser processing is a processing technology that utilizes the characteristics of the interaction between a laser beam and a substance to cut, weld, surface-treat, punch, and micro-machine materials (including metals and non-metals). As an advanced manufacturing technology, laser processing has been widely applied in important sectors of the national economy such as automobiles, electronics, electrical appliances, aviation, metallurgy, and machinery manufacturing, and plays an increasingly important role in improving product quality, labor productivity, automation, pollution-free, and reducing material consumption.
[0003] In laser processing, laser welding is a relatively common processing method. Laser welding is a process of joining two or more materials together by using the high energy density of a laser beam. Laser welding has the advantages of fast welding speed, high weld quality, and small heat-affected zone.
[0004] During the laser welding process, pressure blocks need to be placed on the upper surface of the upper housing and the lower surface of the lower housing to be welded together respectively. Since the welding surface between the upper housing and the lower housing is parallel to the upper surface of the upper housing, when the laser needs to pass through the upper housing to reach the welding surface, the pressure blocks cannot obstruct the penetration of the laser, and the pressure blocks cannot completely press on the upper housing, which may cause displacement between the upper housing and the lower housing and may affect the welding. Utility Model Content
[0005] In order to avoid displacement between the upper housing and the lower housing during the welding process and reduce the impact on welding. The present application provides a plastic housing facilitating laser processing.
[0006] The plastic housing facilitating laser processing provided by the present application adopts the following technical solutions:
[0007] A plastic housing facilitating laser processing, comprising:
[0008] An upper housing and a lower housing, the lower housing is lapped below the upper housing;
[0009] A welding part, arranged between the upper housing and the lower housing, the welding part includes a first processing part and a second processing part to be welded together, wherein the second processing part is connected to the lower housing, the first processing part is connected to the upper housing, the first processing part has penetrability, and the laser can penetrate the first processing part and reach the joint surface of the first processing part and the second processing part;
[0010] The joint surface between the first processing part and the second processing part is inclined with respect to the upper surface of the upper housing or the lower surface of the lower housing.
[0011] By adopting the above technical solution, during processing, laser is irradiated onto the abutting surface, and the upper housing and the lower housing are welded together through the first processing part and the second processing part respectively provided on the upper housing and the lower housing. At this time, since the laser is irradiated obliquely, the pressing block can completely press on the upper housing and the lower housing, avoiding displacement of the upper housing and the lower housing during the welding process and reducing the impact on welding.
[0012] Optionally, the first processing part includes a first connecting block installed on the upper housing and a second connecting block connected to the first connecting block. The second processing part includes a first connecting plate connected to the end of the lower housing and a second connecting plate fixed to the first connecting plate. The first connecting plate and the second connecting plate are integrally provided. The first connecting block and the second connecting block are integrally provided. The angle between the surface where the second connecting plate and the second connecting block abut and the upper surface of the lower housing is set to be an acute angle.
[0013] By adopting the above technical solution, the first processing part includes a first connecting block and a second connecting block, and the second processing part includes a first connecting plate and a second connecting plate. The upper housing and the lower housing can be fixed together through the connection between the first connecting plate and the first connecting block and the welding between the second connecting plate and the second connecting block. The angle set to be an acute angle can match the irradiation angle of the laser and does not affect the pressing of the pressing block.
[0014] Optionally, the side of the upper housing close to the first connecting block is perpendicular to the upper surface of the upper housing.
[0015] By adopting the above technical solution, the side of the upper housing close to the first connecting block is perpendicular to the upper surface of the upper housing. When welding, the laser passes through the connection point between the first connecting block and the upper housing and penetrates to the surface of the second connecting block for laser welding, thereby achieving the effect of welding the upper housing and the lower housing.
[0016] Optionally, a sloping plate is provided between the side of the upper housing close to the first connecting block and the upper surface of the upper housing, and the sloping plate is parallel to the upper surface of the second connecting plate.
[0017] By adopting the above technical solution, the setting of the sloping plate enables the laser to directly reach between the second connecting block and the second connecting plate through the sloping plate, thereby making the welding speed faster. And the sloping plate is parallel to the upper surface of the second connecting plate, enabling the laser to reach the surface to be processed faster and improving the tooling efficiency.
[0018] Optionally, there is a blocking space for welding slag to enter between the first connecting plate and the second connecting block, and the first connecting plate abuts against the lower surface of the upper housing.
[0019] By adopting the above technical solution, there is a blocking space for welding slag to enter between the first connecting plate and the second connecting block. When welding, welding slag will be generated between the second connecting plate and the second connecting block. The welding slag at the position close to the top where the second connecting plate and the second connecting block are in contact will flow into the blocking space and finally solidify. The first connecting plate abuts against the lower surface of the upper housing, so that the welding slag will not flow between the upper housing and the lower housing.
[0020] Optionally, there is also a blocking space for welding slag to enter between the second connecting plate and the second connecting block.
[0021] By adopting the above technical solution, the blocking space between the second connecting plate and the second connecting block is for storing the welding slag generated when the second connecting plate and the second connecting block are welded near the bottom, thereby avoiding the exposure of the welding slag and affecting the appearance. Moreover, the amount of welding slag is small and will solidify, so it will not flow out of the blocking space.
[0022] Optionally, at least one of the upper housing and the lower housing is the upper housing or the lower housing made of an elastic material.
[0023] By adopting the above technical solution, the upper housing and the lower housing are made of an elastic material, so that after the upper housing and the lower housing are welded together, they can be more flexible, and thus the upper housing and the lower housing can be welded together better. And when the pressing block applies pressure to the upper housing and the lower housing, a recoverable elastic deformation is generated, which will not affect the performance of the upper housing and the lower housing.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] 1. By providing the upper housing, the lower housing, the welding part, the second processing part and the first processing part, during processing, laser is irradiated on the abutting surface, and the upper housing and the lower housing are welded together through the first processing part and the second processing part respectively provided on the upper housing and the lower housing. At this time, since the laser is irradiated obliquely, the pressing block can completely press on the upper housing and the lower housing, avoiding the displacement of the upper housing and the lower housing during the welding process and reducing the influence on the welding.

By providing a first connecting plate, a second connecting plate, a first connecting block and a second connecting block, the first connecting plate and the second connecting plate included in the second processing part, and the first connecting block and the second connecting block included in the first processing part, the upper shell and the lower shell can be fixed together through the connection between the first connecting plate and the first connecting block and the welding between the second connecting plate and the second connecting block.

[0027] 3. By providing an inclined plate, the inclined plate enables the laser to directly reach between the second connecting block and the second connecting plate, thus making the welding speed faster. And the angle between the inclined plate and the first connecting block is set to 120° - 135°, which can be adjusted corresponding to different angles between the second connecting block and the second connecting plate.

The upper housing 1 and the lower housing 2 are made of an elastic material, so that after the upper housing 1 and the lower housing 2 are welded together, it can be more flexible, and thus the upper housing 1 and the lower housing 2 can be welded together better. And when the pressing block applies pressure to the upper housing 1 and the lower housing 2, a recoverable elastic deformation is generated, which will not affect the performance of the upper housing 1 and the lower housing 2.
[0044] The implementation principle of a plastic housing facilitating laser processing in the embodiment of the present application is as follows: During processing, laser is irradiated onto the abutting surface, and the upper housing 1 and the lower housing 2 are welded together through the first processing part 31 and the second processing part 32 respectively provided on the upper housing 1 and the lower housing 2.
