Description

Technical Field

[0001] This utility model belongs to the technical field of edge banding machines, and specifically relates to a laser for an edge banding machine. Background Technology

[0002] With the development of laser application technology, laser applications are becoming increasingly diverse. Laser processing equipment offers advantages such as more stable product quality and higher production efficiency, leading to its gradual adoption in various manufacturing industries. When an edge banding machine is working, it irradiates the product surface with a laser beam emitted from a laser source, causing the adhesive on the product surface to reach its melting point. As the relative position of the laser beam and the product moves, the edge banding effect is achieved, with the edge strip adhered to the product surface.

[0003] Currently, such as Figure 7 The existing edge banding machine shown consists of a laser head 8 (or beam shaping head) and a housing 9. The laser head 8 is located outside the housing and connected to the housing 9 via a horizontal adjustment beam. The laser beam generated by the laser pump source located inside the housing 9 is transmitted to the laser head 8 via an armored optical cable arranged on the horizontal adjustment beam. The optical path system inside the laser head 8 then shapes the beam spot. Since the laser pump source and the laser head are installed separately, the armored optical cable arranged on the horizontal adjustment beam needs to be of sufficient length, increasing production costs. Furthermore, after-sales maintenance requires disassembling and assembling the output connector (i.e., fiber optic QBH connector) in a cleanroom environment, while the laser edge banding industry, primarily in furniture factories, is a dusty environment, which can easily damage components. Utility Model Content

[0004] In order to overcome the above-mentioned technical defects, this utility model provides a laser for an edge banding machine, which can solve the technical problems caused by the separate setting of the laser pump source and the laser head in the prior art.

[0040] Combination Figures 1 to 6 As shown, this utility model provides a laser for an edge banding machine, comprising: a housing 10 having a first mounting cavity 110 and a second mounting cavity 120, with a light-emitting hole 130 provided between the first mounting cavity 110 and the second mounting cavity 120; the second mounting cavity 120 communicating with a light-emitting port 140 on the housing 10; a light source system disposed within the first mounting cavity 110, the light source system including a laser pump source 210, an optical cable 220, and an output connector 230, the laser pump source 210 being connected to the output connector 230 via the optical cable 220, the output connector 230 being disposed in the light-emitting hole 130; and an optical path system disposed within the second mounting cavity 120, the optical path system being used to receive a laser beam from the output connector 230 and process it to obtain a processing beam; the optical path system including a spot size adjustment mechanism 310 and a spot height adjustment mechanism 320.

[0041] Specifically, the laser of this application is used in an edge-sealing machine. The laser generates a processing beam to irradiate the product surface, causing the adhesive on the product surface to reach its melting point. As the processing beam moves relative to the product, the edge strip is ultimately adhered to the product surface, achieving an edge-sealing effect. During laser installation, a laser pump source 210 is installed in the first mounting cavity 110, and the optical cable 220 is routed. The output connector 230 is installed on the light output hole 130. A spot size adjustment mechanism 310 and a spot height adjustment mechanism 320 are installed in the second mounting cavity 120. Both the spot size adjustment mechanism 310 and the spot height adjustment mechanism 320 are on the same optical path as the output connector 230. When the laser is working, the laser pump source 210 generates a laser beam, which is transmitted to the output connector 230 via the optical cable 220 and emitted from the output connector 230. The optical path system processes the laser beam from the output connector 230 to obtain a processing beam, and then emits the processing beam from the output port onto the product. Regarding the specific processing process, the spot size adjustment mechanism 310 processes the laser beam to change the size of the processing beam spot so that the spot can meet the processing requirements. The spot height adjustment mechanism 320 can change the height position of the spot, thereby better moving the spot to the processing position of the product.

[0042] Compared to existing technologies, this application innovatively integrates the laser pump source, optical cable, and optical path system onto a housing. The optical cable no longer needs to move with changes in the laser head position, which is beneficial for stable laser output. Furthermore, there is no need to reserve cable length, effectively reducing production costs. In addition, the housing itself can protect the laser pump source, enhancing protection. During after-sales maintenance, only the entire laser needs to be removed from the edge banding machine and moved to a cleanroom environment for easy disassembly and assembly of the output connector (i.e., the fiber optic QBH connector), preventing damage to the device. In existing technologies, because the laser pump source and laser head are not integrated, disassembly and assembly of the output connector can only be performed in the dusty environment of the edge banding machine.

[0043] It should be noted that the output connector can be installed into the light output hole by means of snap-fit, bolt, clamp, etc., and this application does not limit this.

[0044] In this embodiment, the first mounting cavity 110 and the second mounting cavity 120 are arranged in an upper and lower configuration, with the first mounting cavity 110 located above the second mounting cavity 120. In other embodiments, the first mounting cavity 110 and the second mounting cavity 120 can also be arranged in a front and rear configuration or a left and right configuration, requiring only the addition of components to process the optical path.

[0045] In this embodiment, the first mounting cavity 110 is provided with a support portion 111 and a plurality of first mounting holes. When the support portion 111 contacts the laser pump source 210, the second mounting holes 211 on the laser pump source 210 are correspondingly arranged with the first mounting holes. During the installation of the laser pump source 210, the laser pump source 210 can be supported by the support portion 111. At the same time, the support portion 111 also plays an auxiliary positioning role, making it convenient for the second mounting holes on the laser pump source 210 to correspond with the first mounting holes, so that the operator can pass the locking parts (such as bolts) through the second mounting holes in sequence and fix them on the first mounting holes, thereby installing and fixing the laser pump source 210.

[0046] Regarding the fixing of the optical cable 220, in this embodiment, the first mounting cavity 110 is provided with a receiving groove 113, which is used to receive a part of the optical cable 220; the receiving groove 113 is provided with a slot 1131 facing the laser pump source 210; when the laser pump source 210 is installed in the first mounting cavity 110, the laser pump source 210 covers a part of the slot 1131, and the remaining part of the slot 1131 is exposed in the first mounting cavity 110.

[0047] After installation, the laser pump source 210 is located in front of the receiving groove 113, and the rear side of the laser pump source 210 and the groove surface of the receiving groove 113 are used to restrict the position of the optical cable 220. Specifically, before the laser pump source 210 is installed into the first mounting cavity 110, the output connector 230 can be installed onto the light output port 130. Then, part of the optical cable 220 is placed in the receiving groove 113. Next, the laser pump source 210 is placed and installed into the designated mounting position in the first mounting cavity 110. At this time, the laser pump source 210 is located in front of the receiving groove 113, and the laser pump source 210 covers a portion of the slot opening 1131, while the remaining portion of the slot opening 1131 protrudes from the first mounting cavity 110, allowing the optical cable 220 to extend from the first mounting cavity 110 into the receiving groove 113 and to extend from the receiving groove 113 into the first mounting cavity 110. Finally, the position of the optical cable 220 within the first mounting cavity 110 is adjusted. Furthermore, the optical cable 220 can be fixed using curing adhesive or tape.

[0048] Furthermore, the receiving groove 113 and the light output hole 130 are on the same straight line, ensuring that the optical cable 220 above the output connector 230 is straight, avoiding light loss caused by a large bending angle. Furthermore, the first mounting cavity 110 is provided with multiple guide portions 114, each with an arc-shaped guide edge, which guides the bending of the optical cable 220, preventing excessively large bending angles.

[0049] In this embodiment, since the optical cable 220 is located within the first mounting cavity 110 and protected by the housing 10, in order to reduce costs, the optical cable 220 can be an unarmored optical cable 220. In other embodiments, the optical cable 220 can also be an armored optical cable 220 or an optical fiber.

[0050] In this embodiment, the optical path system includes a collimating lens 330, which is disposed corresponding to the light output aperture 130 and located on the light output side of the output connector 230. The collimating lens 330 is used to convert the laser beam from the output connector 230 into a parallel beam (collimated light), thereby suppressing light spot diffusion and maintaining a stable light spot size.

[0051] In this embodiment, the spot size adjustment mechanism 310 further includes a first drive motor 311, a connecting seat 312, a first movable block 313, and a lens holder 314. The first movable block 313 is connected to the lens holder 314, and the lens holder 314 is provided with an adjustment lens. The first drive motor 311 is disposed on the connecting seat 312, and the first drive motor 311 is drivenly connected to the first movable block 313 to change the distance between the adjustment lens and the output connector 230.

[0052] Specifically, in this embodiment, the first drive motor 311 is installed and fixed using the connecting seat 312. The first drive motor 311 drives the first movable block 313 to move, causing the lens holder 314 connected to the first movable block 313 to move up and down, changing the distance between the adjusting lens and the output connector 230, thereby changing the size of the light spot. Preferably, the first drive motor 311 is rotatably connected to the lead screw, and the first movable block 313 is sleeved on the lead screw.

[0053] In this embodiment, the beam height adjustment mechanism 320 includes a second drive motor 321, a fixed base 322, a second movable block 323, a connecting bracket 324, and a lens holder 325. The second movable block 323 is connected to the connecting bracket 324, and the lens holder 325 is provided on the connecting bracket 324. The lens holder 325 is provided with a reflector 326 for changing the laser beam emission direction. The second drive motor 321 is disposed on the fixed base 322 and is drivenly connected to the second movable block 323 to change the height of the reflector 326.

[0054] Specifically, in this embodiment, the second drive motor 321 is installed and fixed using the fixed base 322. The second drive motor 321 drives the second movable block 323 to move, causing the connecting bracket 324 and the lens holder 325 connected to the second movable block 323 to move up and down, changing the distance between the reflector 326 and the output connector 230 (i.e., changing the height of the reflector 326). Based on the principle of reflection, the height of the light spot is thus changed.

[0055] Preferably, the second drive motor 321 is rotatably connected to the lead screw, and the second movable block 323 is sleeved on the lead screw.

[0056] Preferably, the connecting seat 312 is connected to the connecting bracket 324, so that the connecting seat 312 and the first drive motor 311 can move with the connecting bracket 324.

[0057] In this embodiment, the second mounting cavity 120 is provided with a mounting port, and the mounting port is provided with a detachable mounting cover plate 121; the beam height adjustment mechanism 320 is detachably connected to the mounting cover plate 121. In the laser design of this embodiment, the positions of each component are predetermined to ensure that after installation, the output connector 230, the beam size adjustment mechanism 310, and the beam height adjustment mechanism 320 are on the same optical path. This embodiment can facilitate installation by pre-connecting the mounting cover plate 121 to the beam height adjustment mechanism 320, and then installing the mounting cover plate 121 to the mounting port, so that the beam height adjustment mechanism 320 is located within the second mounting cavity 120 and on the optical path. Preferably, the fixing base 322 is detachably connected to the mounting cover plate 121.

[0058] In this embodiment, the housing 10 is composed of a first housing 10 and a second housing 10 connected together, with the first housing 10 positioned above the second housing 10. The front side of the first housing 10 has a front opening with a removable front cover plate. By removing the front cover plate to open the front opening, the optical cable 220 within the first mounting cavity 110 can be routed, and the laser pump source 210 can be installed. The right side of the second housing 10 has the mounting port with a removable mounting cover plate 121. The mounting cover plate 121 is pre-connected to the spot height adjustment mechanism 320, the second drive motor 321, the fixed base 322, the second movable block 323, the connecting bracket 324, and the lens holder 325 for rapid installation.

[0059] In this embodiment, the laser of the edge banding machine further includes a protective door system. The protective door system includes a drive device 410 and a protective door 420 driven and connected to the drive device 410. The protective door 420 opens or closes the light outlet under the drive of the drive device 410. Specifically, when a processing beam needs to be output, the drive device 410 drives the protective door 420 to rise, opening the light outlet; when a processing beam does not need to be output, the drive device 410 drives the protective door 420 to fall, closing the light outlet and preventing dust from entering the second mounting cavity 120 through the light outlet.

[0060] Furthermore, the driving device 410 is a driving cylinder, and the driving device 410 is installed above the second housing 10.

[0061] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
