Description

Technical Field

[0001] This utility model relates to the field of laser processing equipment technology, specifically to a positioning device for a laser marking machine. Background Technology

[0002] Laser marking machines use a laser beam to create permanent marks on the surface of workpieces and are widely used in industries such as electronics, hardware, and plastics. The positioning device, as a core component of the laser marking machine, directly affects the marking accuracy and efficiency.

[0003] The positioning devices of existing laser marking machines have relatively limited functionality, typically only capable of basic positioning. More importantly, most existing devices employ a single-station design, which necessitates machine downtime every time the marking component is changed. Workpiece loading and unloading cannot be synchronized with the marking process, resulting in significant equipment downtime and severely hindering overall production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning device for a laser marking machine, so as to solve the problem that in the existing technology, the machine must be stopped and waited every time the marking element is changed, which seriously restricts the improvement of overall production efficiency.

[0005] According to an embodiment of this utility model, the positioning device of the laser marking machine includes a housing, a working surface formed on the top of the housing, a column and a settling trough on the working surface; a laser marking unit, which includes a display screen mounted on the column and a marking machine body mounted on the column via a lifting device, the marking machine body being located on the upper side of the settling trough; and an intermittent transport unit, which includes a drive source mounted inside the housing and a transport component connected to the drive source via a connecting rod assembly, the transport component being located inside the settling trough and used to drive the material to move intermittently along the length direction of the settling trough.

[0006] Compared with existing technologies, this utility model has the following advantages: The intermittent movement of the transport component within the settling tank is driven by the drive source and linkage assembly of the intermittent transport unit, allowing materials to be conveyed along the length of the settling tank at a set rhythm. Once a material is marked on the underside of the marking machine, the transport component automatically delivers the next material to the marking position while simultaneously removing the marked material. The entire process requires no machine downtime, significantly reducing downtime caused by material changes. The intermittent movement of the transport component and the marking action of the laser marking unit work in synergy. After the marking machine finishes marking the current material, the transport component immediately starts conveying, achieving a seamless connection between marking and conveying. This makes the overall production process smoother, avoiding the cumbersome steps of stopping, loading, positioning, and starting up in the traditional single-station mode, effectively improving marking efficiency.

[0008] Preferably, the linkage assembly includes an active arm that is connected to the drive source for transmission, and a driven arm that is rotatably disposed on the side wall of the settling tank; the free ends of the active arm and the driven arm are respectively hinged to the corresponding connecting arm; and the hinged ends of the active arm and the connecting arm, and the hinged ends of the driven arm and the connecting arm are also hinged together to a linkage arm to realize the synchronous movement of the active arm and the driven arm.

[0009] Preferably, the lifting device includes a screw rotatably disposed inside the column and a movable plate slidably disposed on the column. One end of the movable plate is located inside the column and is threadedly connected to the screw. A turntable for driving the screw to rotate is provided at the top of the screw. The marking machine body is disposed on the movable plate.

[0027] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0028] like Figures 1 to 3 As shown, this utility model embodiment proposes a positioning device for a laser marking machine, which includes a housing 10, a working surface formed on the top of the housing 10, a column 20 and a settling trough 11 on the working surface; a laser marking unit, which includes a display screen 31 mounted on the column 20 and a marking machine body 30 mounted on the column 20 via a lifting device, the marking machine body 30 being located on the upper side of the settling trough 11; and an intermittent transport unit, which includes a drive source 52 mounted inside the housing 10 and a transport component that is connected to the drive source 52 via a connecting rod assembly, the transport component being located inside the settling trough 11, and the transport component being used to drive the material to move intermittently along the length direction of the settling trough 11.

[0029] The detailed working process of this embodiment is as follows: the drive source 52 of the intermittent transport unit and the connecting rod assembly drive the transport component to move intermittently within the settling tank 11, so that the material can be transported along the length of the settling tank 11 at a set rhythm. When a material is marked on the underside of the marking machine body 30, the transport component can automatically send the next material to be processed to the marking position, while removing the marked material. The whole process does not require machine downtime, which greatly reduces the equipment downtime caused by changing materials. The intermittent movement of the transport component and the marking action of the laser marking unit can work together. After the marking machine body 30 marks the current material, the transport component immediately starts conveying, realizing a seamless connection between marking and conveying, making the overall production process smoother.

[0030] like Figure 3 As shown, the transport component includes a transport frame 50 located in the settling tank 11, and multiple sets of top plates 51 evenly distributed on the transport frame 50. Two connecting arms 56 are provided on the side of the transport frame 50 away from the top plates 51.

[0031] The detailed working process of this embodiment is as follows: The top plates 51 can be evenly distributed on the transport frame 50 along the length of the settling tank 11. The top plates 51 are in direct contact with the material, and their number and spacing can be flexibly designed according to the material size. During the transportation stage, the top plates 51 move with the transport frame 50, which can smoothly support the material to complete the position change.

[0032] like Figure 3 As shown, the linkage assembly includes an active arm 53 that is connected to the drive source 52, and a driven arm 55 that is rotatably disposed on the side wall of the sink 11. The free ends of the active arm 53 and the driven arm 55 are respectively hinged to the corresponding connecting arm 56. Furthermore, the hinged ends of the active arm 53 and the connecting arm 56, and the hinged ends of the driven arm 55 and the connecting arm 56 are also hinged together to a linkage arm 54, so as to realize the synchronous movement of the active arm 53 and the driven arm 55.

[0033] The detailed working process of this embodiment is as follows: the active arm 53 and the driven arm 55 are respectively connected to the transport frame 50 through the connecting arm 56. After receiving the power from the drive source 52, the active arm 53 drives the driven arm 55 to move synchronously through the rigid constraint of the linkage arm 54, ensuring that the connecting arms 56 on both sides are subjected to balanced forces. This can effectively counteract the eccentric torque generated by the transport frame 50 during the movement, avoid the transport frame 50 from jamming or tilting due to unilateral force, and ensure the straightness accuracy of the transport trajectory.

[0034] The drive source 52 drives the active arm 53 and the driven arm 55 to rotate, thereby driving the transport frame 50 to move. During the movement, the transport frame 50 intermittently contacts and transports the material. At the same time, the rotation speed of the drive source 52 can be controlled according to the marking speed, so that it rotates slowly or outputs intermittent power. With the rigid transmission of the linkage arm 54 and the driven arm 55, the transport frame 50 obtains stable intermittent motion characteristics. When a material is marked on the underside of the marking machine body 30, the top plate 51 can automatically send the next material to be processed to the marking position, while removing the marked material to form a continuous marking process.

[0035] In this embodiment, the drive source 52 is a motor. In other embodiments, a suitable drive device can be selected according to the actual situation to meet the requirement of driving the active arm 53 to rotate.

[0036] like Figure 2 As shown, the lifting device includes a screw 22 rotatably disposed inside the column 20 and a movable plate 21 slidably disposed on the column 20. One end of the movable plate 21 is located inside the column 20 and is threadedly connected to the screw 22. The top end of the screw 22 is provided with a turntable 23 for driving the screw 22 to rotate. The marking machine body 30 is disposed on the movable plate 21.

[0037] The detailed working process of this embodiment is as follows: With the lifting device set, the height of the marking machine body 30 can be adjusted. Through the threaded connection between the screw 22 and the movable plate 21, the rotational motion of the turntable 23 is converted into the linear lifting motion of the movable plate 21. This screw transmission method has a self-locking function, and can stably maintain the position after the marking machine body 30 is adjusted to the target height, avoiding height deviation caused by vibration during the marking process.

[0038] like Figure 2 As shown, an operating platform 40 and a transition plate 70 are respectively provided at both ends of the sink 11, and the surfaces of the operating platform 40 and the transition plate 70 are smoothly connected to the edge of the sink 11. The operating platform 40 and the transition plate 70 are each provided with a through groove 71, and the cavity of each through groove 71 is directly connected to the cavity of the sink 11 to form a channel for the movement of transported items.

[0039] The detailed working process of this embodiment is as follows: The operating platform 40 and the transition plate 70 are respectively connected to both ends of the settling tank 11. With the connection design between the through channel 71 and the cavity of the settling tank 11, a complete flow channel is constructed from the material loading and marking on the operating platform 40 to the material unloading on the transition plate 70. The transport component can run through the entire working area along this channel, realizing the continuous flow of material from the operating platform 40 into the marking area of ​​the settling tank 11, and then being sent out through the transition plate 70. This avoids the interruption or stagnation of material during the transfer process and ensures the smoothness of continuous operation.

[0040] like Figure 2 As shown, a positioning plate 41 is provided on the operating table 40.

[0041] The detailed working process of this embodiment is as follows: The positioning plate 41 can preset a fixed positioning benchmark according to the specifications of the material to be processed. When loading the material, the operator does not need to repeatedly calibrate the material position. The operator only needs to attach the material to the positioning plate 41 to complete the initial positioning. The clear positioning benchmark makes the loading position more accurate and faster, avoiding the impact on the overall production rhythm due to slow loading or inaccurate positioning.

[0042] like Figure 2 As shown, one end of the transition plate 70 is smoothly connected to the edge of the trough 11, and the end of the transition plate 70 away from the trough 11 is inclined downward to form a slide for the material to slide down.

[0043] The detailed working process of this embodiment is as follows: the end of the transition plate 70 away from the settling tank 11 is inclined downward to form a slide. When the transport component conveys the marked material to the through groove 71 of the transition plate 70, the material can automatically slide down along the inclined slide by its own gravity, without the need for operators to manually remove the material. The entire process does not require machine downtime, further enhancing the equipment's ability to operate continuously. Especially in batch marking scenarios, it can significantly reduce production rhythm interruptions caused by manual intervention.

[0044] like Figure 2 As shown, each top plate 51 is provided with a rubber pad 511.

[0045] The detailed working process of this embodiment is as follows: With the setting of rubber pad 511, rubber pad 511 can effectively prevent the material from sliding or shifting due to inertia, ensuring that the material maintains its initial positioning posture throughout the entire process from the positioning of the operating table 40 to the marking position, reducing the marking position deviation caused by material shift, thereby reducing the rework rate and avoiding interruption of continuous operation process due to rework.

[0046] The elastic properties of the rubber pad 511 can act as a buffer, on the one hand preventing vibration from being transmitted to the material and causing slight displacement, thus ensuring marking accuracy; on the other hand, it can also reduce rigid collisions between the material and the top plate 51.

[0047] like Figure 1 As shown, casters 61 are installed at the four corners of the bottom of the box 10.

[0048] The detailed working process of this embodiment is as follows: With the universal wheels 61, the equipment can be moved flexibly. The operator can push the equipment to adjust its position by a single person without complicated disassembly or heavy auxiliary tools, and quickly adapt to the operation requirements of different production scenarios.

[0049] like Figure 1 As shown, adjustable feet 60 are provided at the four corners of the bottom of the housing 10, and each adjustable foot 60 is located next to the corresponding caster wheel 61.

[0050] The detailed working process of this embodiment is as follows: Although the caster wheel 61 is easy to move, when supported alone, the equipment is prone to slight shaking due to the rolling characteristics of the wheel or small bumps on the ground.

[0051] The height of the adjustable support leg 60 can be adjusted via the thread. After the equipment is moved to the target position, the operator can unscrew the adjustable support leg 60 to make it firmly supported on the ground, replacing the caster wheel 61 as the main support point. This transforms the "rolling contact" between the equipment and the ground into "rigid support," effectively suppressing the vibration generated by the movement of transport parts and the operation of the marking machine body 30 during the marking process. This prevents vibration from being transmitted to the positioning components or materials, ensuring marking accuracy, reducing rework and downtime caused by accuracy deviations, and maintaining the stability of continuous operation.

[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
