Abstract

The present invention discloses a laser lens device with adjustable width of a rectangular laser spot, comprising: a laser lens device body, the laser lens device body comprising a lens box, a collimating lens, an adjusting lens, and a focusing lens, wherein the collimating lens, the adjusting lens, and the focusing lens are all located in the lens box. A laser beam emitted by a laser transmitter enters the laser lens device body, passes through the collimating lens, and reaches the adjusting lens, so that the collimated circular spot is transformed into a strip-shaped spot. The shaped spot is then homogenized by the focusing lens to obtain a rectangular spot. Furthermore, by adjusting the distance between the collimating lens and the adjusting lens, the size of the rectangular spot can be changed to better adapt to the width of different edge sealing strips. During heating, the entire spot range has the same energy, so that the entire edge sealing strip obtains the same effect, thereby avoiding the situation where the center of the circular spot has strong energy and the edge has weak energy when the original laser spot is heated, resulting in inconsistent energy received by the edge sealing strip during edge sealing irradiation and different edge sealing effects.

Description

Technical Field

[0001] The present invention relates to the technical field of laser lenses, and more particularly to a laser lens device with adjustable laser rectangular spot width. Background Art

[0002] Wood board production requires edge banding. As the name suggests, edge banding involves sealing the edges of the board with strips. Edge banding not only enhances the board's appearance but also protects and prolongs its lifespan. Traditional edge banding involves manually attaching the strips to the edges of the board, resulting in low efficiency and prolonged worker exposure to glue, which can be detrimental to workers' physical and mental health.

[0003] To address the shortcomings of manual processing, technological advancements have led to the emergence of laser edge banding machines. These machines utilize a laser hot melt adhesive process, replacing solid glue, to avoid energy waste, reduce worker hours, and lower operating costs. However, laser edge banding machines often use fiber lasers or semiconductor lasers. Due to optical properties, when heated by a laser spot, the circular spot has high energy at the center and low energy at the edges. This results in inconsistent energy received by the edge banding strip during irradiation, resulting in varying edge banding effects. Furthermore, the laser spot size is difficult to adjust, making it unsuitable for edge banding strips of varying widths. Therefore, it is necessary to propose a laser lens device with an adjustable rectangular laser spot width to at least partially address the problems existing in the prior art.

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments so that those skilled in the art can implement the invention with reference to the description.

[0034] It should be understood that terms such as “having”, “including” and “comprising” used herein do not preclude the existence or addition of one or more other elements or combinations thereof.

[0035] like Figure 1-Figure 4As shown, the present invention provides a laser lens device with adjustable laser rectangular spot width, comprising: a laser lens device body 10, which is installed on the output end of a laser emitter 15. The above-mentioned laser lens device body 10 includes a lens box 11, a collimating lens 12, an adjusting lens 13 and a focusing lens 14. Here, the collimating lens 12, the adjusting lens 13 and the focusing lens 14 are all located in the lens box 11, and the adjusting lens 13 is located between the collimating lens 12 and the focusing lens 14. The distance between the collimating lens 12 and the adjusting lens 13 is adjustable. Furthermore, the adjusting lens 13 is set as a microlens.

[0036] The above-mentioned laser lens device body 10 and laser emitter 15 are both equipped on the laser edge banding machine, which performs laser edge banding on furniture panels. When the laser edge banding machine is in use, the laser beam emitted by the above-mentioned laser emitter 15 passes through the laser lens device body 10 and obtains a uniform rectangular light spot. Specifically, the laser beam enters the laser lens device body 10, passes through the collimating lens 12 and reaches the adjusting lens 13, so that the collimated circular light spot is converted into a strip light spot, and then passes through the focusing lens 14 to homogenize the shaped light spot to obtain a rectangular light spot, and by adjusting the distance between the collimating lens 12 and the adjusting lens 13, the size of the rectangular light spot can be changed to better adapt to the width of different edge banding strips, so that the entire light spot range has the same energy during heating, so that the entire edge banding strip obtains the same effect, avoiding the original laser spot heating when the center energy of the entire circular light spot is strong and the edge energy is weak, resulting in inconsistent energy received by the edge banding strip during edge banding irradiation and different edge banding effects.

[0037] Furthermore, in order to adjust the distance between the collimating lens 12 and the adjusting lens 13, a driving motor 111, a driving frame 112, and multiple guide rods 113 are installed in the lens box 11, wherein the collimating lens 12 is installed in the driving frame 112, and the guide rods 113 are passed through the corners of the driving frame 112, and a screw rod 114 is installed on the outer wall of the driving frame 112. Therefore, the driving motor 111 is started by the control device of the above-mentioned laser edge sealing machine, and the driving motor 111 drives the screw rod 114 to rotate, so that the driving frame 112 can move along the screw rod 114 and the guide rod 113, thereby adjusting the distance between the collimating lens 12 and the adjusting lens 13, thereby facilitating the adjustment of the size of the rectangular light spot.

[0038] Furthermore, the above-mentioned laser emitter 15 includes a housing 16, a control module 17 and a laser body 18. Here, the control module 17 and the laser body 18 are both installed in the housing 16, and the laser body 18 is electrically connected to the control module 17, so the control module 17 starts the laser body 18 and outputs the laser beam outward through the connected laser output mechanism, and the laser output mechanism includes an output fiber body 19, an export fiber body 20 and an anti-slip module, wherein the output fiber body 19 is connected to the export fiber body 20 through a shielding tube 31, so the laser body 18 is transmitted to the export fiber body 20 through the output fiber body 19, and then transmitted to the laser lens device body 10 at the output end of the export fiber body 20, and the circular light spot is homogenized into a rectangular light spot through the laser lens device body 10, thereby realizing the above-mentioned function.

[0039] Exemplary optical power homogenization module

[0040] like Figure 5-Figure 8 As shown, further, some embodiments of the present invention provide an output optical fiber body 20 including an inner optical fiber body 201 and an inner cladding 202, and the inner cladding 202 is sleeved on the inner optical fiber body 201, so that the circular inner optical fiber body 201 in the output optical fiber body 20 is homogenized into a rectangular light spot after passing through the above-mentioned laser lens device main body 10, so that the entire light spot range has the same energy during heating, so that the entire edge sealing strip can achieve the same effect.

[0041] Furthermore, the above-mentioned output optical fiber body 20 is also equipped with an external straightening mechanism 21, which is installed on the inner cladding 202. The external straightening mechanism 21 keeps the output optical fiber body in a straight state to prevent the output optical fiber body 20 from bending during use and affecting the homogenization effect.

[0042] Specifically, the above-mentioned external straightening mechanism 21 includes two locking rings 22, two flange rings 23, multiple skeleton retaining rings 24, and an internal skeleton mechanism 25, wherein a circumferential locking groove 203 is opened on the rear side of the end of the inner cladding 202, and multiple skeleton retaining rings 24 are evenly distributed on the inner cladding 202. Here, the flange ring 23 is installed in the circumferential locking groove 203, and the internal skeleton mechanism 25 is installed between the flange ring 23 and the adjacent skeleton retaining ring 24, as well as between two adjacent skeleton retaining rings 24. Then, the output optical fiber body is kept in a straight state through the skeleton retaining ring 24, the internal skeleton mechanism 25 and other components, thereby preventing the output optical fiber body from bending during use and affecting the homogenization effect.

[0043] Furthermore, the above-mentioned internal skeleton mechanism 25 includes an outer support sleeve 251, multiple inner pillars 252, an elastic rod 253, and an inner spring 254. The multiple inner pillars 252 are evenly distributed on the circumferential outer wall of the inner cladding 202, and the outer support sleeve 251 is sleeved on the multiple inner pillars 252. A C-shaped pull tab 255 is installed in the side wall of the inner pillar 252, and a docking column 256 is installed on the outer wall. The elastic rod 253 is connected to the two docking columns 256, and the inner spring 254 is installed in the inner cavity of the elastic rod 253. Here, the C-shaped pull tab 255 is connected to the inner spring 254 through a pull rope 257, wherein the pull rope 257 is passed through the docking column 256, so the internal skeleton mechanism 25 on the output optical fiber body can package the output optical fiber body from the outside. Of course, it should be noted that the operator needs to pay attention to avoid external force acting on the output optical fiber body 20 to cause the output optical fiber body 20 to bend. When the optical fiber body 20 is bent by external force, the inner skeleton mechanism 25 can reset the bending trend. Specifically, the elastic rod 253 and the inner spring 254 have good elastic force. Here, the elastic rod 253 and the inner spring 254 push the inner support 252 outward, so that the elastic rod 253 and the inner spring 254 can withstand the external force.

[0044] Furthermore, a plurality of first straightening holes 231 are provided on the above-mentioned flange ring 23, a plurality of second straightening holes 241 are also provided on the skeleton retaining ring 24, a third straightening hole 258 is provided on the inner pillar 252, and a locking notch groove 221 is provided on the locking ring 22, wherein the straightening wire 26 is passed through the first straightening hole 231, the second straightening hole 241, and the third straightening hole 258, and a locking block (not shown) is installed on the end of the straightening wire 26, and the locking block is clamped in the locking notch groove 221, and then the flange ring 23, the skeleton retaining ring 24, the inner pillar 252 and other components are passed together through the above-mentioned straightening wire 26, thereby further increasing the overall force-bearing capacity of the external straightening mechanism 21, and better maintaining the derived optical fiber body 20 in a straight state, avoiding the derived optical fiber body 20 from bending during use and affecting the homogenization effect.

[0045] Exemplary second anti-slip module

[0046] like Figures 9-13As shown, generally speaking, the service life of the laser fiber is 100,000 hours, so the operator does not need to replace the laser fiber frequently. Furthermore, since the above-mentioned output fiber body 19 and the lead-out fiber body 20 are connected by the shielding tube 31, they will inevitably become loose and detached after long-term use, which will make the output light beam effect between the output fiber body 19 and the lead-out fiber body 20 poor. Therefore, in some embodiments of the present invention, a specific structure of the anti-detachment module 30 is provided. The anti-detachment module 30 further connects the output fiber body 19 and the lead-out fiber body 20 to prevent the connection part of the two from being exposed to the outside world, and also provides protection for the two to prevent the two from skewing when outputting the laser beam after long-term use, thereby affecting the output effect.

[0047] Among them, the above-mentioned anti-dropping module 30 includes a left anti-dropping cap 40 and a right anti-dropping cap 50. Here, a left anti-dropping cavity 401 is opened in the left anti-dropping cap 40. Here, the left anti-dropping cap 40 is installed on the rear end of the box body 16, and a right anti-dropping cavity 501 is opened in the right anti-dropping cap 50. The right anti-dropping cavity 501 corresponds to the left anti-dropping cavity 401. The output optical fiber body 19 is arranged in the left anti-dropping cavity 401, and the output optical fiber body 20 is arranged in the right anti-dropping cavity 501. Through the left anti-dropping cavity 401 and the right anti-dropping cavity 501, the optical fiber body 20 is arranged in the right anti-dropping cavity 501. The output optical fiber body 19 and the lead-out optical fiber body 20 can be fixed together; two C-shaped positioning grooves 402 are provided on the inner wall of the left anti-dropping cap 40, and a C-shaped positioning protrusion 502 corresponding to the C-shaped positioning groove 402 is provided on the inner wall of the right anti-dropping cap 50. Therefore, when the left anti-dropping cap 40 and the right anti-dropping cap 50 are close to each other and docked to prevent them from dropping out, the C-shaped positioning protrusion 502 is inserted into the C-shaped positioning groove 402, further preventing the left anti-dropping cap 40 and the right anti-dropping cap 50 from being separated and affecting the connection of the lead-out optical fiber body 20 and the output optical fiber body.

[0048] Furthermore, a left anti-slip mechanism 41 is installed in the left anti-slip cap 40, and a right anti-slip mechanism 51 is installed in the right anti-slip cap 50. In this way, after the output optical fiber body 19 and the lead-out optical fiber body 20 are respectively inserted into the left anti-slip cap 40 and the right anti-slip cap 50, the operator can connect the left anti-slip cap 40 and the right anti-slip cap 50 to prevent each other from slipping off. Then, the left anti-slip mechanism 41 can firmly fix the lead-out optical fiber body 20 to prevent it from slipping off, and the right anti-slip cap 50 can firmly fix the output optical fiber body 19 to prevent it from slipping off. Even if the output optical fiber body 19 is subjected to external force, the two will not separate. Furthermore, the output optical fiber body 19 and the lead-out optical fiber body 20 have a better effect in transmitting laser.

[0049] Among them, in order to achieve the above-mentioned technical effects, the left anti-slip mechanism 41 here includes a left retaining ring 411, multiple left bellows 412, and a left inner tire ring 413. Correspondingly, in order to install the above-mentioned components, a first left circumferential inner groove 403 and a second left circumferential inner groove 404 are opened in the left anti-slip cap 40, and the first left circumferential inner groove 403 is connected to the second left circumferential inner groove 404 through multiple left inflation channels 405, and the left retaining ring 411 and multiple left bellows 412 are installed in the first left circumferential inner groove 403, and the left inner tire ring 413 is installed in the second left circumferential inner groove 404, and the left bellows 412 is sealed with the left inflation channel 405, so the left retaining ring 411 can push against the left bellows 412 and communicate with the left inner tire ring 413 through the above-mentioned left inflation channel 405. They are interconnected and further filled with inert gas in the left bellows 412, the left inflation channel 405, and the left inner tire ring 413. In order to enable the right anti-slip mechanism 51 to act on the left anti-slip mechanism 41, a plurality of left insertion holes 406 are provided on the inner wall of the left anti-slip cap 40. In this way, when the left anti-slip cap 40 and the right anti-slip cap 50 mutually prevent the output optical fiber body 19 and the derived optical fiber body 20 from slipping off, the right anti-slip mechanism 51 can act on the left retaining ring 411, so that the left retaining ring 411 moves inward, and then the plurality of left bellows 412 are compressed inward by the left retaining ring 411, so that the inert gas in the left bellows 412 is further filled into the left inner tire ring 413, so that the left inner tire ring 413 swells up to fix the derived optical fiber body 20 to prevent it from slipping off.

[0050] Furthermore, the above-mentioned right anti-slip mechanism 51 includes a right retaining ring 511, multiple right bellows 512, and a right clamp inner tire ring 513. Correspondingly, in order to install the above-mentioned components, a first right circumferential inner groove 503 and a second right circumferential inner groove 504 are opened in the right anti-slip cap 50, and the first right circumferential inner groove 503 is connected with the second right circumferential inner groove 504 through multiple right inflation channels 505, and the right retaining ring 511 and multiple right bellows 512 are installed in the first right circumferential inner groove 503, and the right clamp inner tire ring 513 is installed in the second right circumferential inner groove 504, and the right bellows 512 is sealed with the right inflation channel 505, so the right retaining ring 511 can push against the left and right bellows 512 and be connected with the right clamp inner tire ring 513 through the above-mentioned right inflation channel 505, further The corrugated tube 412, the right inflation channel 505, and the right inner tire ring 513 are filled with inert gas. In order to enable the right anti-slip mechanism 51 to act on the left anti-slip mechanism 41, a plurality of right insertion rods 514 are provided on the right retaining ring 511, and a plurality of right insertion rods 514 are installed on the right retaining ring 511. In this way, when the left anti-slip cap 40 and the right anti-slip cap 50 prevent each other from slipping off and fix the output optical fiber body 19 and the output optical fiber body 20, the right insertion rod 514 passes through the right insertion rod 514 and then corresponds to the left insertion hole 406. The left retaining ring 411 is compressed inwardly by the right insertion rod 514, thereby realizing the anti-slip effect of the left anti-slip mechanism 41 on the output optical fiber body 19. Similarly, the right inner tire ring 513 in the right anti-slip mechanism 51 is supported by the inert gas filled therein to fix the output optical fiber body 20 to play an anti-slip effect.

[0051] Furthermore, the left anti-slip mechanism 41 further includes a plurality of left auxiliary mechanisms 42, the left auxiliary mechanism 42 includes a left angle rod 421, a left inner anti-slip splint 422, and a plurality of left auxiliary holes 407 are provided in the left anti-slip cap 40, the left auxiliary holes 407 are connected to the first left circumferential inner groove 403, and the left angle rod 421 is passed through the left auxiliary hole 407 and corresponds to the left retaining ring 411, and the left inner anti-slip splint 422 is connected to the left angle rod 421. Therefore, when the left retaining ring 411 moves inward, the left angle rod 421 is pushed by the left retaining ring 411, and then the left angle rod 421 moves in the left auxiliary hole 407 toward the output optical fiber body 20, so that the multiple left inner anti-slip clamps 422 clamp the output optical fiber body 19, so that the output optical fiber body 19 is further fixed, and the left inner anti-slip clamp 422 has multiple left anti-slip lines 423, so that the anti-slip function is further enhanced;

[0052] Similarly, the right anti-slip mechanism 51 also includes multiple right auxiliary mechanisms 52, which include a right angle rod 521 and a right inner anti-slip splint 522. Multiple right auxiliary holes 507 are opened in the right anti-slip cap 50, and the right auxiliary hole 507 is connected to the first right circumferential inner groove 503. The right angle rod 521 is passed through the right auxiliary hole 507 and corresponds to the right retaining ring 511. The right inner anti-slip splint 522 is connected to the right angle rod 521, so when the right retaining ring 511 moves inward, the right angle rod 521 is pushed by the right retaining ring 511, and then the right angle rod 521 moves toward the output optical fiber body in the right auxiliary hole 507, so that the multiple right inner anti-slip splints 522 clamp the output optical fiber body 20, so that the output optical fiber body 20 is further fixed, and there are multiple right anti-slip lines 523 on the right inner anti-slip splint 522, so that the anti-slip function is further enhanced.

[0053] Furthermore, an auxiliary anti-slipping mechanism 60 is respectively installed in the left anti-slipping cap 40 and the right anti-slipping cap 50. A semicircular circumferential half groove 601 is respectively opened on the inner wall of the left anti-slipping cap 40 and the right anti-slipping cap 50, and an anti-slipping cavity 602 is arranged inside. The anti-slipping cavity 602 is communicated with the first left circumferential inner groove 403 (first right circumferential inner groove 503) through a first anti-slipping hole 603, and the first anti-slipping hole 603 is communicated with the circumferential half groove 601 through a second anti-slipping hole 604. The auxiliary anti-slipping mechanism 60 includes an inner spring body 61, an anti-slipping baffle 62, and an anti-slipping guide rod 63. The inner spring body 61 and the anti-slipping baffle 62 are arranged in the anti-slipping cavity 602, and the inner spring body 61 pushes against the anti-slipping baffle 62 to push the sealing adhesive into the anti-slipping guide rod 63, and the anti-slipping guide rod 63 is installed in the first anti-slipping hole 603. There is a guide hole 631 inside, so when the left retaining ring 411 (right retaining ring 511) moves inward, the outer end of the right insertion rod 514 enters the first left circumferential inner groove 403, and the inner end enters the first right circumferential inner groove 503. Here, anti-slip grooves 515 are respectively opened at the outer end and the inner end of the right insertion rod 514, and the anti-slip guide rod 63 is inserted into the anti-slip groove 515, so that the left anti-slip cap 40 and the right anti-slip cap 50 are connected to each other in an anti-slip manner; and the sealing adhesive enters the second anti-slip hole 604 through the guide hole 631 until it reaches the circumferential half groove 601, and then the two sealing adhesives in the two circumferential half grooves 601 contact each other and are fixed, thereby preventing external moisture from entering the left anti-slip cap 40 and the right anti-slip cap 50, and avoiding excessive humidity from affecting laser transmission.
