Description

Technical Field

[0001] This utility model relates to the field of marking machine technology, and in particular to an IC customized version of ultraviolet marking machine. Background Technology

[0002] Laser marking machines, with their high precision and efficiency, are widely used in many fields such as automobiles, packaging, and jewelry. Ultraviolet (UV) laser marking machines, in particular, can not only leave clear patterns and text on material surfaces during the marking process, but also perform micro-processing and cutting operations. This is crucial for industries requiring fine processing and marking of products. For example, an IC UV marking machine is a marking device used to mark IC (integrated circuit) chips. It uses a high-energy-density UV laser beam to irradiate the surface of the IC chip, causing the surface material to vaporize or change color, thus leaving a permanent mark.

[0003] In related technologies, laser marking machines typically consist of a base, a lifting column, a laser, and a marking head. The lifting column is located on the top surface of the base, and the laser and marking head are mounted on the lifting column via sliding seats and slide along the column to adjust the height of the marking head. This type of laser marking machine has the disadvantages of being inconvenient to move and carry, and lacking protection for the marking head and laser. Utility Model Content

The sliding mating block is disposed on the support base, and a slide groove extending along the bottom wall of the receiving cavity to the top wall of the receiving cavity is formed on the sliding mating block. The slide rail is disposed on the mounting plate and is slidably connected to the inner wall of the slide groove. The laser and the marking head are both connected to the mounting plate.

[0012] In one embodiment, the lifting guide mechanism further includes a stiffening plate that connects the support base to the bottom wall of the receiving cavity.

[0013] In one embodiment, the support mechanism includes a guide post, a limiting ring, a sleeve, and a support plate. The guide post is connected to the bottom wall of the receiving cavity.

[0039] This utility model proposes an IC-customized version of the ultraviolet marking machine 100.

[0040] Please see Figures 1 to 3In one embodiment of this utility model, the IC customized ultraviolet marking machine 100 includes a housing 1, a support mechanism 2, a laser 3, a lifting and guiding mechanism 4, a marking head 5, and a light path turning mechanism 6. A receiving cavity 1a is formed inside the housing 1. The bottom wall of the receiving cavity 1a is provided with a marking port 11a. The support mechanism 2 is provided on the bottom wall of the receiving cavity 1a. The laser 3 is provided on the support mechanism 2. The lifting and guiding mechanism 4 is provided on the bottom wall of the receiving cavity 1a and connected to the laser 3 to guide the laser 3 to move up and down. The marking head 5 is located between the laser 3 and the bottom wall of the receiving cavity 1a and is correspondingly provided with the marking port 11a. The light path turning mechanism 6 connects the laser 3 and the marking head 5 and is used to guide the laser from the laser 3 to the marking head 5. The outgoing light path of the laser 3 and the incoming light path of the marking head 5 are arranged in parallel and opposite directions.

[0041] The IC-customized UV marking machine 100 proposed in this embodiment has a box-type movable structure, which can be placed directly on a workbench or packed in a carrying case for outdoor operation. It is suitable for marking the surface of materials such as metal, plastic, and leather. The whole machine includes a shell 1, a support mechanism 2, a laser 3, a lifting and guiding mechanism 4, a marking head 5, and a light path turning mechanism 6. The shell 1 is a rectangular box with an internal cavity 1a and a marking port 11a on the bottom wall. When the box is closed, it isolates the internal optical components from the external environment, providing dustproof and impact-proof protection. The support mechanism 2 is fixed to the bottom wall of the cavity 1a and is used to support the laser 3. Its structure is in the form of a bracket, with the top wall of the support mechanism 2 abutting against the bottom wall of the laser 3 to support the laser 3. The laser 3 is placed on the support mechanism 2 and provides the laser beam required for processing. Its output light path points horizontally from the laser emission port on the side wall of the laser 3 to the input end of the light path turning mechanism 6. The lifting guide mechanism 4 is fixed to the bottom wall of the receiving cavity 1a and connected to the laser 3. It guides the laser 3 to move vertically to adjust the distance between the laser focus and the workpiece surface. This mechanism can adopt a guide rail-slider structure or a lead screw-nut structure, and the driving method can be manual or motor-driven. The marking head 5 is located between the laser 3 and the bottom wall of the receiving cavity 1a, aligned with the marking port 11a. The marking head 5 receives the laser beam guided by the optical path turning mechanism 6 and scans and marks the workpiece. The optical path turning mechanism 6 connects the laser 3 and the marking head 5. It turns the horizontally emitted laser beam from the laser 3 into a vertically downward direction after one reflection, and then into a horizontal direction after another reflection before entering the marking head 5. A reflector can be installed on the optical path turning mechanism 6 to deflect the optical path.

[0042] In this embodiment, the laser 3, marking head 5, lifting and guiding mechanism 4, and optical path steering mechanism 6 are all located inside the outer casing 1, forming a closed structure for overall protection. Simultaneously, the laser 3 and marking head 5 are connected via the optical path steering mechanism 6, ensuring that the laser 3's output optical path and the marking head 5's incident optical path are horizontally aligned and in opposite directions. This effectively reduces the overall lateral dimension of the machine, making the IC-customized UV marking machine 100 easier to carry. It is understandable that reducing the overall lateral dimension means decreasing the projected area of ​​the IC-customized UV marking machine 100's outer contour on the horizontal plane, allowing it to be used in narrower spaces and facilitating portability.

[0043] In summary, this embodiment protects the laser head 5 and the laser 3 by housing the laser 3, the marking head 5, and the lifting guide device within the housing 1, and by providing a support mechanism 2 within the housing 1 to support the laser 3. Furthermore, by using an optical path steering mechanism 6 to connect the marking head 5 and the laser 3, the marking head 5 is positioned between the laser 3 and the bottom wall of the receiving cavity 1a, optimizing the spatial distribution of the marking head 5 and the laser 3. Compared to traditional laser marking machines, the marking head 5 and the laser 3 are vertically distributed, reducing the lateral dimensions of the IC-customized UV marking machine 100, making it easier to move and carry. Therefore, it improves the portability, protection, and adaptability of the IC-customized UV marking machine 100 to confined spaces.

[0044] Further, please refer to Figure 8 In one embodiment of the present invention, the outer shell 1 includes a base plate 11 and a cover 12. The base plate 11 is provided with a marking port 11a. The base plate 11 and the cover 12 enclose each other to form a receiving cavity 1a.

[0045] In this embodiment, the outer shell 1 consists of a base plate 11 and a cover 12, which are detachably connected to allow for easy access to the internal space for adjustment and maintenance of the laser 3, lifting and guiding mechanism 4, optical path steering mechanism 6, and marking head 5. The base plate 11 is a rigid flat plate with a marking port 11a corresponding to the marking head 5; the base plate 11 also serves as the mounting reference for all internal mechanisms. The cover 12 is a downward-opening box-shaped component that matches the shape of the base plate 11. The base plate 11 and the cover 12 are detachably connected by screws or clips to form a receiving cavity 1a. When it is necessary to calibrate the internal optical path or replace the laser 3, the cover 12 can be separated from the base plate 11 simply by loosening the connector, exposing all functional modules within the receiving cavity 1a; after maintenance, it can be closed and tightened again to restore its original state, thus significantly improving maintenance convenience while maintaining protective performance.

[0046] Furthermore, please refer to Figure 8In one embodiment of the present invention, the cover 12 includes a front panel 121, a rear panel 122, a left side panel 123, a right side panel 124, and a top panel 125. The front panel 121, the right side panel 124, the rear panel 122, and the left side panel 123 are detachably connected in sequence, and the left side panel 123 is connected to the front panel 121. The top ends of the front panel 121, the right side panel 124, the rear panel 122, and the left side panel 123 are all detachably connected to the top panel 125.

[0047] In this embodiment, the housing 12 is composed of five independent plates: a front panel 121, a right side panel 124, a rear panel 122, a left side panel 123, and a top panel 125. Each side panel is connected end-to-end with screws or pins to form a rectangular frame, and the end of the left side panel 123 is then joined to the beginning of the front panel 121 for closure. Threaded holes or slots can be machined at the top of the four side panels, allowing for detachable connection with corresponding through holes or tongues on the top panel 125. The plates can be further designed with uniform thickness and positioning steps to prevent misalignment during assembly. Before assembly and transportation, the five plates can be stacked and bundled, significantly reducing the overall volume compared to the housing 12, facilitating transport. On-site assembly can be quickly completed by tightening screws or inserting pins in sequence. If any side panel is damaged, it can be replaced individually, reducing maintenance costs.

[0048] Further, please refer to Figure 8 and Figure 9 In one embodiment of the present invention, the front panel 121 is provided with a first window 121a, which is disposed toward the light path turning mechanism 6. The cover 12 also includes a first cover plate 126, which is detachably covered on the side of the first window 121a that is away from the receiving cavity 1a.

[0049] In this embodiment, considering that while the housing 12 improves the protection of the laser 3 and the marking head 5, it also increases the difficulty of maintenance, a first window 121a and a first cover plate 126 are provided on the front panel 121. The first window 121a faces the reflector, reflector mounting bracket, and sleeve in the optical path turning mechanism 6. The window shape can be rectangular or circular, with the opening area limited to the minimum size to allow the insertion of a general optical adjustment tool and the removal of the lens, and limited to the maximum size to avoid excessively weakening the rigidity of the front panel 121. The first cover plate 126 is a thin plate with the same shape as the outer contour of the first window 121a. The material can be the same as the front panel 121 (such as aluminum alloy), or lightweight plastic can be used to reduce weight. A sealing gasket or sealing ring can be provided on the side facing the first window 121a to achieve a dustproof seal when closed. The first cover plate 126 is detachably connected to the front panel 121 by screws, magnetic attraction, or rotating buckles. Therefore, the first window 121a and the first cover plate 126 together form a partially openable and closable channel, which significantly reduces the complexity of optical path maintenance without sacrificing the overall protection of the machine, and achieves the technical effect of improving the convenience of maintenance.

[0050] Further, please refer to Figure 2 and Figure 10 In one embodiment of the present invention, the rear panel 122 is provided with a second window 122a, which is disposed facing the laser 3. The cover 12 also includes a wiring board 127, which is detachably covered on the side of the second window 122a facing the receiving cavity 1a.

[0051] In this embodiment, to facilitate the fixing and maintenance of the connection cable between the laser 3 and the control host, a second window 122a is provided on the rear panel 122, and a detachable wiring board 127 is provided in the second window 122a. This allows the IC customized UV marking machine 100 to fix and organize the cable while maintaining overall enclosure. The second window 122a is positioned directly opposite the electrical interface area at the tail of the laser 3. The shape of the second window 122a can be rectangular or oblong, etc., and its area is slightly larger than the area required for the laser 3 connector wire harness to be inserted into the housing. The wiring board 127 is located inside the housing, and the wiring board 127 has a crimping thin edge around its perimeter. A crimping block is provided on the rear panel 122 extending along the crimping thin edge. The crimping block and the rear panel 122 clamp the crimping thin edge and are fixed with screws, which not only improves the strength of the local connection but also provides a positioning reference for the wiring board 127. Furthermore, when the plug on the connection cable of the external control host is connected to the junction box 127, the plug is hidden inside the second window 122a to prevent the plug from being bumped or damaged, thus avoiding damage to the plug or the junction box 127.

[0052] The junction box 127 matches the shape of the second window 122a, and the material can be insulating engineering plastic or anodized aluminum sheet, etc. Various fixing holes are provided on the board surface. The diameter, spacing, and arrangement of the fixing holes can be selected according to the space required for wiring, which will not be elaborated here. It should be noted that the laser 3 and the marking head 5 can be raised and lowered within the housing 1. Therefore, the data cable interface of the laser 3 is connected to the junction box 127 via an adapter cable. The adapter cable has sufficient length to accommodate the raising and lowering of the laser 3. The end of the adapter cable that connects to the junction box 127 has an adapter interface. When connecting the laser 3 inside the housing 1 to an external control host, simply insert the plug at the end of the control host's connection cable into the adapter interface on the adapter cable. The end of the adapter cable with the adapter interface is fixed by the inner wall of the hole on the junction box 127. Furthermore, the connection between the end of the adapter cable with the adapter interface and the junction box 127 can be further reinforced with screws or other fasteners. When the terminal block 127 is damaged due to repeated plugging and unplugging, only the terminal block 127 needs to be replaced, without having to replace the entire rear panel 122, thus reducing maintenance costs.

[0053] Further, please refer to Figures 3 to 5In one embodiment of this utility model, the optical path steering mechanism 6 includes a first reflector mounting bracket 61, a first sleeve 62, a second sleeve 63, and a second reflector mounting bracket 64. The first reflector mounting bracket 61 connects the laser 3 to the first sleeve 62, and the second reflector mounting bracket 64 connects the second sleeve 63 to the marking head 5. The first sleeve 62 and the second sleeve 63 are slidably sleeved together. The first reflector mounting bracket 61 has a first mounting surface 611, and the second reflector mounting bracket 64 has a second mounting surface 641. The first mounting surface 611 is set at a 45° angle to the outgoing optical path of the laser 3, and the second mounting surface 641 is set at a 45° angle to the incident light of the marking head 5.

[0054] In this embodiment, to guide the light path from the laser 3 to the marking head 5, the light path steering mechanism 6 consists of four functional components: a first reflector mounting bracket 61, a first sleeve 62, a second sleeve 63, and a second reflector mounting bracket 64. The first reflector mounting bracket 61, after mounting the reflector, can be used to deflect the horizontal beam output from the laser 3 downwards by 90°. Its structure is a right-angled triangular prism mounting block. The interior of the first reflector mounting bracket 61 forms an L-shaped hollow channel. The two ends of the L-shaped hollow channel are respectively located on the two right-angled end faces of the right-angled triangular prism. The inclined surface of the right-angled triangular prism also has an opening communicating with the L-shaped hollow channel, and the periphery of the opening forms a first mounting surface 611. One right-angled end face is fixed to the laser 3 output end with screws, and the other right-angled end face is fixed to the first sleeve 62 through a mounting groove. The first mounting surface 611 forms a 45° angle with the laser 3 output light path. A centering adjustment frame is provided on the first mounting surface 611. The centering adjustment frame can fix and finely adjust the position of the reflector to adjust the light path. The centering adjustment frame can be an optical centering adjustment frame of Soleber KM05CP, KM100CP, or KM200CP. One end of the first sleeve 62 is connected to the first reflector mounting bracket 61 through a mounting groove and the thread on the inner wall of the groove, and the other end is a sliding guide section. The outer wall is provided with a guide key or anti-rotation edge, and the wall thickness ensures that no visible deformation occurs within the adjustment stroke. One end of the second sleeve 63 is connected to the second reflector mounting bracket 64 through a mounting groove and the thread on the inner wall of the groove, and the inner hole of the other end is slidably sleeved with the outer wall of the first sleeve 62. The structure of the second reflector mounting bracket 64 is set with reference to the first reflector mounting bracket 61. After the reflector is installed, the second reflector mounting bracket 64 can be used to deflect the vertical beam output from the first sleeve 62 and the second sleeve 63 by 90° and then project it horizontally into the marking head 5. The marking head 5 includes a galvanometer 51 and a field lens 52. The galvanometer 51 is used to deflect the laser beam to achieve vector marking and dot matrix marking, etc. The field lens 52 is used to focus the laser beam to maintain focal stability and correct aberrations, etc. The setting of the marking head 5 is relatively mature, so it will not be described in detail.

[0055] This embodiment achieves a telescopic adjustment function through the sliding sleeve relationship between the first sleeve 62 and the second sleeve 63, making it easy to adapt to different installation spaces and positions. For example, in this embodiment, both the laser 3 and the marking head 5 are mounted on the mounting plate 44. Different models of the mounting plate 44 may cause changes in the installation positions of the laser 3 and the marking head 5, and consequently, the distance between them. Therefore, the telescopic adjustment of the first sleeve 62 and the second sleeve 63 in this embodiment can well adapt to different mounting plates 44.

[0056] Understandably, in this embodiment, the first mounting surface 611 is set at a 45° angle to the outgoing light path of the laser 3, and the second mounting surface 641 is set at a 45° angle to the incident light of the marking head 5. This 45° reflection follows the geometric optical law that the angle of incidence equals the angle of reflection, making the first reflector mounting bracket 61, the first sleeve 62, the second sleeve 63, and the second reflector mounting bracket 64 vertically distributed, reducing the lateral space occupied. The sliding sleeves are mechanically equivalent to variable-length light guide tubes, which not only maintain the optical path closure to prevent dust intrusion, but also ensure that the reflected beam always propagates along the center line of the sleeve through sliding cooperation, avoiding light spot drift. Therefore, after the reflector is installed, the first reflector mounting bracket 61 and the second reflector mounting bracket 64 provide two 90° turns respectively. The first and second sleeves 63 achieve adaptive optical path length through sliding sleeve connection. This combination maintains stable beam pointing during the lifting and lowering of the whole machine, thereby achieving high-precision and easy-to-maintain optical path turning function within the small-volume housing 1.

[0057] Further, please refer to Figure 5 and Figure 6 In one embodiment of the present invention, the lifting guide mechanism 4 includes a support base 41, a sliding mating block 42, a slide rail 43, and a mounting plate 44. The support base 41 is connected to the bottom wall of the receiving cavity 1a. The sliding mating block 42 is disposed on the support base 41, and a sliding groove extending from the bottom wall of the receiving cavity 1a to the top wall of the receiving cavity 1a is formed on the sliding mating block 42. The slide rail 43 is disposed on the mounting plate 44 and is slidably connected to the inner wall of the sliding groove. The laser 3 and the marking head 5 are both connected to the mounting plate 44.

[0058] In this embodiment, the support base 41 is fixed to the bottom wall of the receiving cavity 1a by screws or pins, providing a vertical bearing reference. A sliding mating block 42 is located on one side of the support base 41, and a groove is formed on the side of the sliding mating block 42 facing away from the support base 41. The groove extends vertically along the bottom wall of the receiving cavity 1a towards the top wall. The groove cross-section can be rectangular or arc-shaped to facilitate cutting and processing. It can also be set as a dovetail shape, T-shape, etc., to improve the constraint on the slide rail 43. For example, the dovetail shape can self-lock and prevent detachment. The number of slide rails 43 and grooves is the same and there is at least one set. When the load is large or the span is long, a symmetrical arrangement of double slide rails 43 and double grooves can be used to resist the eccentric load moment. The slide rail 43 is locked to the mounting plate 44 by screws, and its outer contour forms a high-precision sliding fit with the inner wall of the groove. The mounting plate 44 also provides a common mounting plane for the laser 3, the optical path steering mechanism 6, and the marking head 5, ensuring that the relative positions of the three remain unchanged throughout the entire lifting and lowering process, thus maintaining the optical path.

[0059] Further, please refer to Figure 6 In one embodiment of the present invention, the lifting guide mechanism 4 further includes a stiffening plate 45, which connects the support base 41 and the bottom wall of the receiving cavity 1a.

[0060] In this embodiment, a stiffening plate 45 is added to the side of the support base 41 facing away from the sliding block. The stiffening plate 45 is perpendicular to the wall of the support base 41 and the bottom wall of the receiving cavity 1a. The stiffening plate 45 can be a metal plate with a thickness similar to that of the side wall of the support base 41. It is connected to both the side wall of the support base 41 and the bottom wall of the receiving cavity 1a by screws or welding to form a triangular support structure. This structure diverts the vertical load and lateral inertial force on the support base 41 to the base plate 11, reduces local stress concentration, prevents the mating surface of the slide groove and the slide rail 43 from jamming due to slight deformation of the base, and improves the stability of the support base 41 and the connection strength between the support base 41 and the bottom wall of the receiving cavity 1a.

[0061] Further, please refer to Figure 3 , Figure 4 and Figure 7 In one embodiment of this utility model, the support mechanism 2 includes a guide post 21, a limiting ring 22, a sleeve 23, and a support plate 24. The guide post 21 is connected to the bottom wall of the receiving cavity 1a. The limiting ring 22 is sleeved on the guide post 21, and a stop screw is rotatably passed through the limiting ring 22. The stop screw abuts against the guide post 21. The sleeve 23 is slidably sleeved on the guide post 21 and located on the side of the limiting ring 22 facing away from the bottom wall of the receiving cavity 1a. The support plate 24 is located at the end of the sleeve 23 away from the limiting ring 22 and is arranged parallel to the bottom wall of the receiving cavity 1a. The support plate 24 abuts against the laser 3.

[0062] In this embodiment, the guide post 21, the limiting ring 22, the sleeve 23, and the support plate 24 together constitute a vertically sliding and adjustable limiting mechanism. The guide post 21 is a metal rod, the lower end of which is vertically fixed to the bottom wall of the receiving cavity 1a through a snap-fit ​​hole and screws, serving as the reference axis of the entire support mechanism 2. The limiting ring 22 is an annular metal part, sleeved on the outside of the guide post 21 and able to slide up and down along the post; a radial threaded through hole is opened on the side wall of the ring, and the stop screw is screwed into the hole and abuts against the cylindrical surface of the guide post 21, achieving positioning at any height through friction. Loosening the stop screw allows for readjustment of the height, while tightening it immediately locks it in place. The sleeve 23 is a hollow cylindrical structure, with its inner diameter clearance-fitted with the guide post 21 to ensure low-friction sliding. The lower end face of the sleeve 23 abuts against the upper end face of the limiting ring 22, and the upper end face of the sleeve 23 is rigidly connected to the support plate 24 through a snap-fit ​​hole and screws, or it can be directly welded. The length of sleeve 23 is determined according to the required lifting stroke of laser 3. When the limiting ring 22 is locked, sleeve 23 obtains a defined support position. Support plate 24 is a rectangular or circular flat plate. The upper surface of support plate 24 directly contacts the base of laser 3, serving to support laser 3, etc. Furthermore, a soft pad can be attached to the top surface of support plate 24 to reduce frictional damage between support plate 24 and the outer shell 1 of laser 3. In this embodiment, support mechanism 2 provides support for laser 3 and can adapt to changes in the height of laser 3.

[0063] Further, please refer to Figure 8 and Figure 9 In one embodiment of the present invention, a third window 124a is provided on the side wall of the receiving cavity 1a, the third window 124a is disposed facing the support mechanism 2, and the third window 124a is covered by a second cover plate 128.

[0064] In this embodiment, a third window 124a and a second cover plate 128 are added to the side wall of the receiving cavity 1a. The second cover plate 128 is detachably attached to the third window 124a by screws, forming an openable maintenance channel. When the support mechanism 2 is completely closed by the housing 12, the second cover plate 128 can be removed without disassembling the housing 12, thereby adjusting the support mechanism 2 through the third window 124a to adjust the height of the laser 3.

[0065] Specifically, the third window 124a is located on the right side plate 124, directly opposite the area of ​​the guide post 21, the limiting ring 22, and the sleeve 23 of the support mechanism 2. The outer contour of the window is rectangular or circular, and the opening size is limited to allow a person to reach in and operate the stop screw and pull out the sleeve 23, while the upper limit is to avoid excessively weakening the overall rigidity of the side wall. The second cover plate 128 is a thin plate with the same shape as the outer contour of the third window 124a and slightly larger than the third window 124a. The material can be the same as the side wall (such as aluminum alloy or steel plate). Furthermore, a sealing gasket is attached to the inner surface of the second cover plate 128. The cover plate is detachably connected to the side wall by screws, magnets, or buckles. When closed, it blocks external dust and moisture, and when open, it exposes the support mechanism 2 for adjustment operations.

[0066] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
