Description

Technical Field

[0001] This utility model relates to the field of laser engraving technology, and more specifically, to a portable laser engraving device. Background Technology

[0002] In automobile production, powertrain engine and transmission production lines widely utilize laser marking equipment to engrave serial numbers, product information, and quality groupings on various parts. There is also significant demand for laser marking equipment in other areas such as workpiece rework, tool information marking on machine tools, and nameplates for various tools in daily work. However, because these precision electronic systems frequently malfunction or exceed the structural limits for marking, they impact actual production. For some highly integrated large laser systems, damage necessitates contacting the manufacturer for repair and temporarily using spare equipment or having workers manually mark the markings. However, equipment repair is costly and time-consuming, while manual marking carries quality risks. Therefore, it is necessary to develop portable laser equipment to meet temporary usage needs.

[0003] Existing technologies have incorporated related designs. For example, Chinese Patent Publication No. CN112475617A discloses a portable laser marking machine, in which a field lens, galvanometer, and touchscreen are fixedly connected to the chassis, improving portability. However, because the field lens and galvanometer of the aforementioned portable laser marking machine are directly exposed and fixedly mounted on the side wall of the chassis, these precision components lack protection and are easily damaged by collisions during transport and storage, affecting the equipment's accuracy and lifespan. Utility Model Content

[0004] This invention addresses the problem of insufficient protection for precision components in portable laser devices, which leads to easy damage, by providing a portable laser engraving device.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a portable laser engraving device, comprising: a chassis, an industrial control component disposed inside the chassis, a slide table slidably connected to the top of the chassis, an engraving head assembly fixedly connected to the slide table, the engraving head assembly being electrically connected to the industrial control component, wherein when the slide table moves to a first position, the vertical projection of the output end of the engraving head assembly is located within the vertical projection of the chassis, and when the slide table moves to a second position, the vertical projection of the output end of the engraving head assembly is located outside the vertical projection of the chassis.

[0006] In the technical solution of this utility model, the various components are integrated into the chassis, which can improve the portability of the laser marking device and meet the needs of temporary use in various scenarios. In this solution, the marking head assembly is slidably connected to the top of the chassis via a slide table, so that the marking head can extend out of the chassis or be stored on top of the chassis as needed. When the marking head is in the first position, it is in a non-working state and stored on top of the chassis, which can reduce the collision of the marking head during carrying and storage and improve the service life of the device. When the marking head is in the second position, it is in a working state, at which time the output end of the marking head extends from the top of the chassis without affecting the normal use of the device.

[0007] Furthermore, the engraving head assembly includes a laser head, a connecting block, a galvanometer, and a field lens. The laser head is connected to the galvanometer via the connecting block, and the field lens is connected to the bottom of the galvanometer. The field lens is the output end of the engraving head. The slide has a positioning through hole in the vertical direction corresponding to the position of the field lens, and the field lens is matched and placed in the positioning through hole.

[0008] In this solution, by opening positioning through holes at the corresponding positions of the field lens on the slide, the field lens can be positioned and installed without affecting the normal etching operation of the field lens. At the same time, the positioning through holes can protect the field lens in the circumferential direction, thereby improving the service life of the device.

[0009] Furthermore, the slide is provided with an arc-shaped groove, and the outer peripheral surface of the laser head is matched and placed on the arc-shaped groove.

[0010] In this solution, the laser head is positioned and installed using an arc-shaped groove, and the marking head can be fully positioned using a positioning through hole, which facilitates assembly and use.

[0011] Furthermore, a slide rail is fixedly connected to the top of the chassis along the horizontal direction, and a slider is fixedly connected to the bottom of the slide table, with the slider slidably connected to the slide rail.

[0012] In this solution, by setting slide rails and sliders, the slide table can slide on the top of the chassis, which facilitates the movement of the engraving head.

[0013] Furthermore, a base plate is provided between the slide table and the chassis, the base plate is fixedly connected to the top of the chassis, the base plate is provided with a sliding groove along the moving direction of the slide table, and a limit post is connected to the bottom of the slide table, the limit post being placed in the sliding groove.

[0014] In this solution, a base plate is set up, and a sliding groove is opened in the base plate. The limiting post at the bottom of the slide table cooperates with the sliding groove to limit the position, so that the slide table can be stably slid laterally to adjust its position.

[0015] Furthermore, the top two sides of the chassis are respectively connected to handles that can rotate in the vertical direction. The handles can rotate upward to restrict the engraving head assembly to the first position.

[0016] In this design, a handle is provided to facilitate carrying the device and to limit the marking head assembly, preventing the marking head from protruding outside the casing when the device is lifted, thus providing protection.

[0017] Furthermore, the handle includes a hand-held portion and a connecting portion. One end of the connecting portion is hinged to the chassis, and the other end of the connecting portion is fixedly connected to the hand-held portion. When the hand-held portion is located on the top of the chassis, the connecting portion can prevent the engraving head assembly from moving from the first position to the second position.

[0018] In this design, the hand-held part is used for gripping, the connecting part serves as a connection, and the connecting part can be flipped to block the movement of the engraving head, thus blocking the end of the engraving head when the device is lifted.

[0019] Furthermore, the industrial control components include an industrial control host, a laser, a circuit board, a touch screen, a power supply, and an air switch. The industrial control host, laser, circuit board, touch screen, and power supply are connected by a line, and the air switch is connected in the line. The industrial control host, laser, circuit board, touch screen, power supply, and air switch are all fixedly connected to the chassis.

[0020] In this solution, the industrial control host controls the overall operation of the equipment, the laser is used to generate laser light to supply the engraving head, the circuit board is used to drive the touch screen, the touch screen is used for user operation, the power supply is used to supply power to each component, and the air switch serves to connect and protect the circuit.

[0021] Furthermore, the industrial control host is located at the bottom of the chassis, and the laser is located on one side above the industrial control host.

[0022] In this solution, placing the industrial control host at the bottom reduces the impact of heat accumulation on the host's heat dissipation, while placing the laser on one side at the top creates a horizontal heat dissipation channel within the chassis, utilizing the laser's own heat dissipation system for cooling.

[0023] Furthermore, the chassis has air inlets and air outlets on its two side walls along the length of the laser.

[0024] In this design, by setting air inlets and outlets on both sides of the chassis, corresponding to the two sides along the length of the laser, it is beneficial for heat dissipation inside the chassis.

[0025] Compared with the prior art, the beneficial effects of this utility model are: This portable laser engraving device slidably connects the engraving head assembly to the top of the chassis via a slide table, allowing the engraving head to extend outside the chassis or be stored on top of the chassis as needed. When the engraving head is in the first position, it is in a non-working state and stored on top of the chassis, which reduces collisions to the engraving head during carrying and storage, and improves the service life of the device. When the engraving head is in the second position, it is in a working state, at which time the output end of the engraving head extends from the top of the chassis without affecting the normal use of the device.

[0030] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings: Example 1 refer to Figures 1 to 6 This embodiment discloses a portable laser engraving device, including a chassis 1, an industrial control component 2 disposed inside the chassis 1, a slide table 3 slidably connected to the top of the chassis 1, an engraving head assembly 4 fixedly connected to the slide table 3, the engraving head assembly 4 being electrically connected to the industrial control component 2, when the slide table 3 moves to a first position, the vertical projection of the output end of the engraving head assembly 4 is located within the vertical projection of the chassis 1, when the slide table 3 moves to a second position, the vertical projection of the output end of the engraving head assembly 4 is located outside the vertical projection of the chassis 1.

[0031] In this embodiment, the various components are integrated into the chassis 1, which improves the portability of the laser marking device and is suitable for temporary use in various scenarios. The marking head assembly 4 is slidably connected to the top of the chassis 1 via a slide table 3, allowing the marking head to extend out of the chassis 1 or be stored on top of the chassis 1 as needed. When the marking head is in the first position, it is in a non-working state and stored on top of the chassis 1, reducing collisions during carrying and storage and improving the device's lifespan. When the marking head is in the second position, it is in a working state, with its output end extending from the top of the chassis 1, without affecting normal device operation. The chassis 1 can adopt a side-flip structure for easy assembly and maintenance.

[0032] refer to Figure 1 and Figure 5The engraving head assembly 4 includes a laser head 41, a connecting block 42, a galvanometer 43, and a field lens 44. The laser head 41 is connected to the galvanometer 43 via the connecting block 42. The field lens 44 is connected to the bottom of the galvanometer 43 and serves as the output end of the engraving head. A positioning through-hole 31 is provided on the slide 3 at a position corresponding to the field lens 44 in the vertical direction, and the field lens 44 is fitted into the positioning through-hole 31. In this embodiment, by providing the positioning through-hole 31 on the slide 3 at a position corresponding to the field lens 44, the field lens 44 can be positioned and installed without affecting its normal engraving operation. Simultaneously, the positioning through-hole 31 provides circumferential protection for the field lens 44, improving the device's lifespan. The depth of the positioning through-hole 31 matches the downward extension length of the field lens 44, or the depth of the positioning through-hole 31 is slightly greater than the downward extension length of the field lens 44, thus completely enclosing the field lens 44 circumferentially to prevent impacts. The positioning through hole 31 is provided through the slide 3, so a positioning through hole 31 with a suitable depth can be obtained by using a slide 3 of a specific thickness.

[0033] refer to Figure 1 The slide 3 is provided with an arc-shaped groove 32, and the outer peripheral surface of the laser head 41 is matched and placed on the arc-shaped groove 32. In this embodiment, the laser head 41 is limited and installed by the arc-shaped groove 32, and the marking head can be completely positioned by the positioning through hole 31, which facilitates assembly and use.

[0034] refer to Figure 5 A slide rail 11 is fixedly connected to the top of the chassis 1 along a horizontal direction, and a slider 12 is fixedly connected to the bottom of the slide table 3. The slider 12 is slidably connected to the slide rail 11. In this embodiment, by setting the slide rail 11 and the slider 12, the slide table 3 can slide on the top of the chassis 1, thereby facilitating the movement of the engraving head. The slide rail 11 can be set along the length direction of the top of the chassis 1, matching the length direction of the engraving head, which can maximize the use of the top space of the chassis 1 for storage.

[0035] refer to Figure 5 and Figure 6 A base plate 5 is provided between the slide table 3 and the chassis 1. The base plate 5 is fixedly connected to the top of the chassis 1. The base plate 5 has a sliding groove 51 along the moving direction of the slide table 3. A limiting post 33 is connected to the bottom of the slide table 3 and is placed in the sliding groove 51. In this embodiment, by setting the base plate 5 and opening the sliding groove 51 in the base plate 5, the limiting post 33 at the bottom of the slide table 3 cooperates with the sliding groove 51 to limit the position, so that the slide table 3 can be stably slid laterally to adjust its position. The slide rail 11 can be fixedly connected to the base plate 5 by bolts, and the base plate 5 is connected to the top of the chassis 1 by bolts.

[0036] Example 2 refer to Figures 1 to 3This embodiment is similar to Embodiment 1, except that in this embodiment, the top two sides of the housing 1 are respectively connected to handles 6 that can rotate in the vertical direction. The handles 6 can rotate upward to restrict the engraving head assembly 4 to a first position. In this embodiment, by providing handles 6, it is convenient to carry the device, and the handles 6 can limit the engraving head assembly 4, preventing the engraving head from extending outside the housing 1 when the device is lifted, thus providing protection.

[0037] refer to Figure 1 The handle 6 includes a grip portion 61 and a connecting portion 62. One end of the connecting portion 62 is hinged to the housing 1, and the other end of the connecting portion 62 is fixedly connected to the grip portion 61. When the grip portion 61 is located at the top of the housing 1, the connecting portion 62 can prevent the engraving head assembly 4 from moving from the first position to the second position. In this embodiment, the grip portion 61 is used for holding, and the connecting portion 62 serves as a connection. Simultaneously, the connecting portion 62 can be flipped to block the movement of the engraving head, thus blocking the end of the engraving head when the device is lifted. The connecting portion 62 blocks the side of the galvanometer 43. When the device is carried by hand, the middle of the connecting portion 62 interferes with the movement of the galvanometer 43, preventing the engraving head from slipping out during carrying. When the equipment needs to be moved, the slide 3 is pushed back to the top limit of the housing 1, and the handle 6 is closed for transport. The handle 6 provides ample gripping space. When the handle 6 is closed, it prevents the slide 3 of the engraving head from sliding out. When the handle 6 is lowered, it does not interfere with the movement of the galvanometer 43 and does not affect the use of the device.

[0038] refer to Figure 6 The handle 6 on one side can be folded up from above to fit flush with the top of the chassis, so as not to block the display area on the side of the chassis.

The industrial control host 21, laser 22, circuit board 23, touch screen 24, and power supply 25 are connected via wiring, and the air switch 26 is connected within the wiring. All components are fixedly connected to the chassis 1. In this embodiment, the industrial control host 21 controls the overall operation of the equipment. The laser 22 generates laser light to supply the etching head. The circuit board 23 drives the touch screen 24, which is used for user operation. The power supply 25 supplies power to each component, and the air switch 26 connects and protects the wiring. The laser 22 can be an IPG fiber laser, allowing for different output powers within the same size, facilitating selection and installation. The air switch 26 is a standard 1P type, located at the bottom rear of the equipment.

[0040] refer to Figure 4 The industrial control host 21 is located at the bottom of the chassis 1, and the laser 22 is located on one side above the industrial control host 21. In this embodiment, placing the industrial control host 21 at the bottom reduces the impact of heat accumulation on its heat dissipation, while placing the laser 22 on one side creates a horizontal heat dissipation channel within the chassis 1, utilizing the laser 22's own heat dissipation system. The air switch 26 is located at the bottom rear of the equipment, without obstructing the heat dissipation channel or the equipment's exhaust vents. The power supplies 25 are distributed inside the chassis 1, primarily at the top, and combined with other available spaces to fully utilize the chassis 1's space. In this embodiment, each electrical device is equipped with a separate power supply 25 and an independent air switch 26 to ensure electrical safety.
