Description

Technical Field

[0001] This invention relates to the field of laser processing technology, and more specifically to a laser machine. Background Technology

[0002] The electronics industry has extremely high precision requirements for components. Laser technology can cut precision stencils or membrane structures made of various materials (such as metals and ceramics) with extremely high accuracy, ensuring that the size and shape of the product meet the design requirements, improving the overall manufacturing quality and reliability, while the cut surface is smooth and free from burrs and deformation that could affect subsequent processing or use.

[0003] In the existing manufacturing process of non-junction solar cell screens, in order to ensure that the printed grid lines engraved by the laser machine are accurately distributed along the weft or warp lines, a film with the engraved pattern needs to be placed on the screen before using the laser machine. The position between the film and the screen needs to be manually adjusted so that the printed grid line pattern is in the set position on the screen. Then, the laser machine's vision system uses the Mark points (optical positioning points) on the film as a reference for engraving. However, existing laser machines require manual handling of the film for alignment, and the degree of automation needs to be improved.

[0004] Therefore, it is necessary to provide a new type of laser machine. Summary of the Invention

[0005] In view of the above-mentioned problems existing in the prior art, the purpose of this invention is to provide a laser machine that can replace manual labor to align film sheets and improve the degree of automation.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A laser engraving machine is provided, comprising a platform, a camera module, and a transmission device. The camera module is movably disposed above the platform, and the transmission device is disposed on the side of the platform. The platform is used to place a screen printing plate. The transmission device includes a slide, a swing arm, and a movable frame. The slide slides vertically, the swing arm is hinged to the slide, and the movable frame is connected to the swing arm via a traction rope. The film is spread out on the movable frame. When the slide moves upward, causing the movable frame to move upward past the platform, the movable frame can swing with the swing arm under gravity and approach the screen printing plate on the platform, thereby causing the film to swing downward with the movable frame and parallel to the screen printing plate. The movable frame is also provided with a support module. The downward movement of the camera module can engage with the support module, and thus, by moving the camera module relative to the screen printing plate on the platform, the film can be moved to complete alignment with the screen printing plate.

[0007] Furthermore, the transmission device also includes a housing, which is mounted on the side of the base on the platform. The slide is housed in the housing. When the slide moves down to the first position, that is, when the swing arm swings up to the vertical position of the movable frame, the hinge axis between the slide and the swing arm is located on the side of the movable frame away from the platform.

[0008] Furthermore, the top of the box is provided with a cover, which flips up and closes the top opening of the box when the slide moves down and drives the movable frame into the box.

[0009] Furthermore, a winding reel is installed on the swing arm, and a traction rope is wound on the winding reel, with one end of the traction rope connected to the movable frame.

[0010] Furthermore, the spreading module includes a support claw and a sleeve. The support claw has a strip-shaped structure and is connected to the film. The sleeve is connected to the movable frame, and the support claw and the sleeve are slidably engaged. There are four support claws, which are distributed at the four corners of the film. Each of the four support claws is slidably connected to the movable frame through the sleeve. Thus, when the four support claws move away from the film and move to the end position, they spread the film open so that the film is flat and unfolded. That is, when the film is flat and unfolded, the end of the support claw near the sleeve abuts against the bottom end of the sleeve, thereby limiting the sliding of the support claw on the sleeve.

[0011] Furthermore, the camera module includes a camera and an illumination module disposed below the camera. The camera and the illumination module are detachably connected. The illumination module includes a base frame, a lamp assembly, and a power connection structure. The lamp assembly is mounted on the base frame, and the power connection structure is located on the upper surface of the base frame and is electrically connected to the lamp assembly. A charging arm is provided on the side of the camera, and an electromagnet is also provided on the side of the camera. When energized, the electromagnet can magnetically attract the base frame, thereby attracting the illumination module to the camera. At the same time, the charging arm is connected to the power connection structure to provide power to the lamp assembly. The lamp assembly is an energy storage structure.

[0012] Furthermore, the laser machine also includes a base, on which a first slide table that moves along the X-axis is provided, a second slide table that moves along the Y-axis perpendicular to the X-axis is provided on the first slide table, and a third slide table that moves along the Z-axis perpendicular to both the X-axis and the Y-axis is provided on the second slide table, and a camera module is mounted on the third slide table.

[0013] Furthermore, the platform includes a base and a rotary table disposed above the base.

[0014] Furthermore, a guide block is provided on the swing arm and between the winding wheel and the movable frame. The guide block has a guide hole, through which the traction rope passes and connects to the movable frame.

[0015] Furthermore, the expansion module also includes a clamping block, which has a thin sheet structure. The clamping block is connected to the corner of the film and extends along the side length of the film. The support claw is fixedly connected to the clamping block.

[0016] The beneficial effects of this invention are as follows: The laser machine provided by this invention includes a platform, a camera module, and a transmission device. The camera module is movably mounted above the platform, and the transmission device is mounted on the side of the platform. The platform is used to place a screen printing plate. The transmission device includes a slide, a swing arm, and a movable frame. The slide slides vertically, the swing arm is hinged to the slide, and the movable frame is connected to the swing arm via a traction rope. The film is laid out on the movable frame. When the slide moves upward, causing the movable frame to move upward past the platform, the movable frame can swing with the swing arm under gravity and approach the screen printing plate on the platform. This causes the film to swing downward with the movable frame and lie parallel to the screen printing plate. The movable frame is also provided with a support module. The downward movement of the camera module can engage with the support module. Thus, by moving the camera module relative to the screen printing plate on the platform, the film can be moved to be aligned with the screen printing plate, thereby replacing manual alignment of the film and improving the degree of automation.

Therefore, the phrases "in one embodiment," "in some embodiments," or "in some of these embodiments" appear in various places throughout the specification, and not all refer to the same embodiment. Furthermore, in one or more embodiments, a particular feature, structure, or characteristic may be combined in any suitable manner.

[0033] Please refer to Figures 1 to 9 As shown, a laser machine provided by the present invention will now be described. The laser machine includes a platform 10, a camera module 20, and a transmission device 30. The camera module 20 is movably disposed above the platform 10, and the transmission device 30 is disposed on the side of the platform 10. The platform 10 is used to place the screen printing plate 100. The transmission device 30 includes a slide 31, a swing arm 32, and a movable frame 33. The slide 31 is slidably disposed in the vertical direction, the swing arm 32 is hinged to the slide 31, and the movable frame 33 is connected to the swing arm 32 by a traction rope 341. The film 200 is spread out on the movable frame 33 and on the slide 31. When the movable frame 33 moves upward past the platform 10, it can swing with the swing arm 32 under the action of gravity and approach the screen 100 on the platform 10. This causes the film 200 to swing down with the movable frame 33 and lie parallel to the screen 100. The movable frame 33 is also equipped with a support module 36. The camera module 20 can move down and engage with the support module 36. Then, by moving the camera module 20 relative to the screen 100 on the platform 10, the film 200 can be moved to be aligned with the screen 100, thereby replacing manual alignment of the film and improving the degree of automation.

[0034] In some embodiments, the film 200 has a square-shaped structure.

[0035] like Figure 1As shown, in some embodiments, the laser machine further includes a base 70, on which a first slide 40 that moves along the X-axis is provided, a second slide 50 that moves along the Y-axis perpendicular to the X-axis is provided on the first slide 40, and a third slide 60 that moves along the Z-axis perpendicular to both the X-axis and the Y-axis is provided on the second slide 50. The camera module 20 is mounted on the third slide 60, so that the camera module 20 can move along the X-axis, Y-axis or Z-axis with the third slide 60.

[0036] like Figure 2 As shown, in some embodiments, the stage 10 includes a base 11 and a turntable 12 disposed above the base 11. The turntable 12 is used to place the screen printing plate 100, so that the screen printing plate 100 can be driven to perform circumferential rotation to adjust the placement angle of the screen printing plate 100. In conjunction with the three-axis movement of the camera module 20, the film 200 can be accurately aligned to a specified position on the screen printing plate 100.

[0037] like Figure 2 As shown, in some embodiments, the transmission device 30 further includes a housing 39, which is mounted on the side of the base 11 on the platform 10. The slide 31 is housed within the housing 39. When the slide 31 moves down to the first position, i.e., the swing arm 32 swings up to the vertical position of the movable frame 33, the hinge axis between the slide 31 and the swing arm 32 is located on the side of the movable frame 33 away from the platform 10. Thus, the center of gravity of the movable frame 33 will apply a driving swing to the swing arm 32. The force of the arm 32 twisting downward toward the platform 10 drives the movable frame 33 to abut against the side wall of the box 39 near the platform 10. When the slide 31 moves upward and drives the movable frame 33 to pass over the platform 10, the movable frame 33 loses the support of the side wall of the box 39. As a result, the movable frame 33 will swing with the arm 32 toward the screen 100 on the platform 10 under the action of gravity, so that the film 200 swings down with the movable frame 33 and abuts against the screen 100 in parallel.

[0038] like Figure 5 As shown, in some embodiments, the slide 31 and the swing arm 32 are hinged together by a hinge structure 37. The rotation of the swing arm 32 about the hinge structure 37 relative to the slide 31 downward and close to the platform 10 is restricted by the lower swing limit 38. Specifically, the lower swing limit 38 is disposed between the slide 31 and the swing arm 32. When the swing arm 32 rotates downward relative to the slide 31 to drive the movable frame 33 to be parallel and close to the screen 100 on the platform 10, the lower swing limit 38 blocks between the slide 31 and the swing arm 32, thereby preventing the swing arm 32 from rotating relative to the slide 31, so that the swing arm 32 is kept in a state in which the movable frame 33 is parallel to the screen 100. More precisely, in this embodiment, the lower swing limit 38 is fixedly installed on the slide 31.

[0039] like Figure 5As shown, in some embodiments, the top of the box 39 is provided with a top cover 391. When the slide 31 moves down and drives the movable frame 33 into the box 39, the top cover 391 flips to close the top opening of the box 39, thereby storing the film 200 into the box 39 and preventing dirt generated by laser engraving from contaminating the pattern on the film 200. Specifically, the top cover 391 can be connected to the box 39 by a torsion spring, so that the top cover 391 always has the tendency to flip and close the top opening of the box 39, so that the top cover 391 realizes the function of automatic flipping.

[0040] like Figure 4 As shown, in some embodiments, a take-up reel 34 is mounted on the swing arm 32, and a traction rope 341 is wound on the take-up reel 34. One end of the traction rope 341 is connected to the movable frame 33. When the take-up reel 34 rotates to wind up the traction rope 341, it can pull the movable frame 33 toward the swing arm 32 until the movable frame 33 abuts against the swing arm 32, locking the movable frame 33 with the swing arm 32. This allows the movable frame 33 to swing with the swing arm 32, preventing the movable frame 33 from swinging randomly and causing accidental impacts. In addition, when the movable frame 33 swings down and is parallel to the screen 100, by controlling the take-up reel 34 to loosen, the movable frame 33 can move independently away from the swing arm 32, thereby facilitating the adjustment of the relative position between the film 200 and the screen 100.

[0041] like Figure 4 As shown, in some embodiments, a guide block 35 is provided on the swing arm 32 and between the take-up reel 34 and the movable frame 33. The guide block 35 has a guide hole 351, through which the traction rope 341 passes and connects to the movable frame 33. This facilitates guiding the movable frame 33 to a predetermined position on the swing arm 32 when the take-up reel 34 winds up the traction rope 341, pulling the movable frame 33 closer to the swing arm 32. More specifically, the take-up reel 34 is driven by a take-up driver 342, which is mounted on the swing arm 32.

[0042] like Figure 6As shown, in some embodiments, the spreading module 36 includes a support claw 361 and a sleeve 364. The support claw 361 has a strip-shaped structure and is connected to the film 200. The sleeve 364 is connected to the movable frame 33, and the support claw 361 and the sleeve 364 are slidably engaged. There are four support claws 361, which are distributed at the four corners of the film 200. Each of the four support claws 361 is slidably connected to the movable frame 33 through the sleeve 364. Thus, when the four support claws 361 move away from the film 200, the film can be spread outwards. When the film 200 moves to the end position, it is spread out to make the film 200 flat and unfolded. That is, when the film 200 is flat and unfolded, the end of the support claw 361 near the sleeve 364 abuts against the bottom end of the sleeve 364, so that the sliding limit of the support claw 361 on the sleeve 364 is achieved. Through the above technical solution, the film 200 can maintain the original state of the material when it is not subjected to external force, avoiding the film 200 from being subjected to long-term force and thus reaching the fatigue limit prematurely, thereby improving the service life of the film 200.

[0043] like Figure 1 As shown, in some embodiments, the spreading module 36 further includes a clamping block 363, which has a thin sheet structure. The clamping block 363 is connected to the corner of the film 200 and extends along the side length of the film 200. The support claw 361 is fixedly connected to the clamping block 363, so that the support claw 361 is connected to the film 200 through the clamping block 363. In this way, the clamping block 363 can increase the contact surface between the support claw 361 and the film 200, and avoid stress concentration that could damage the film 200.

[0044] like Figure 8 As shown, in some embodiments, the camera module 20 includes a camera 21 and an illumination module 22 disposed below the camera 21. When the camera module 20 moves down, causing the illumination module 22 to enter the center position of the four support claws 361, the four support claws 361 are forced to move away from the film 200 and to the end position under the pushing of the illumination module 22, thereby unfolding the film 200. At the same time, the camera module 20 translates along the surface of the screen 100, thereby driving the movable frame 33 and the film 200 to translate along the surface of the screen 100. With the rotation of the screen 100, the film 200 can be moved to complete the alignment with the screen 100.

[0045] like Figure 6 As shown, in some embodiments, a clamping arm 362 is provided at one end of the support claw 361 near the center of the film 200. When the lighting module 22 enters the center position of the four support claws 361, the lighting module 22 abuts against the clamping arm 362, increasing the contact surface between the support claw 361 and the lighting module 22, so that the lighting module 22 and the support claw 361 are stably abutted.

[0046] In some embodiments, the camera module 20 uses visual guidance to position and align the moving film 200 with the screen 100. The principle of visual guidance positioning is to use the camera to transmit the target to be detected as an image to a dedicated image processing system, then convert the feature information of the image into a processable digital signal, extract the features of the target through different algorithms, such as area, position, length, quantity, etc., and finally output the calculation results according to the preset allowable degree or other conditions, so as to realize functions such as automatic recognition, detection measurement, and guided positioning. The specific visual guidance positioning is a mature existing technology and will not be described in detail here.

[0047] like Figure 7 As shown, in some embodiments, the camera 21 and the illumination module 22 are detachably connected. This allows the illumination module 22 to separate from the camera 21 when the camera module 20 moves downwards, causing the illumination module 22 to push the four support claws 361 to move and unfold the film 200. This maintains the unfolded state of the film 200. Simultaneously, the camera 21 can move detached from the illumination module 22 to identify the Mark points on the film 200. During this process, the illumination module 22 can maintain the unfolded state of the film 200 by pushing the four support claws 361. Specifically, refer to... Figure 7 As shown, the lighting module 22 includes a base frame 221, a lamp assembly 222, and a power connection structure 223. The lamp assembly 222 is mounted on the base frame 221, and the power connection structure 223 is located on the upper surface of the base frame 221 and is electrically connected to the lamp assembly 222. A charging arm 23 is provided on the side of the camera 21, and an electromagnet 24 is also provided on the side of the camera 21. When energized, the electromagnet 24 can magnetically attract the base frame 221, thereby attracting the lighting module 22 to the camera 21. At the same time, the charging arm... The charging arm 23 is connected to the power connection structure 223 to supply power to the lamp assembly 222. The lamp assembly 222 is a power storage structure so that the lighting module 22 can work even when it is detached from the camera 21. When the charging arm 23 is in contact with the power connection structure 223, the lamp assembly 222 can store power. In this embodiment, the charging arm 23 and the power connection structure 223 are contact charging structures. It is understood that in some other embodiments not shown in the figure, the charging arm 23 and the power connection structure 223 can also be wireless charging structures.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
