Description

Technical Field

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

[0002] With the rapid development of the garment industry, the demand for surface pattern processing of buttons, as important decorative and functional components, is increasing. Laser engraving technology, due to its high precision, non-contact processing, and ability to engrave complex patterns and text, has become the mainstream technology for button surface decoration. Laser engraving devices use a laser beam to precisely etch the button surface, enabling high-quality personalized customization and are widely used in the clothing, bag, and other industries. Currently, button laser engraving devices typically consist of a positioning mechanism and a laser processing system, completing the processing by fixing the button and performing laser engraving. However, with increasing demands for production efficiency and automation, existing devices still have room for further optimization in terms of processing continuity and stability.

[0003] In existing technologies, button laser engraving devices typically use linear conveying mechanisms (such as conveyor belts or mechanical pushers) to transport buttons from their initial position to the processing position for laser engraving. However, linear conveying mechanisms lack flexible movement control. When a single button gets stuck or deviates in position during the conveying process, it can easily lead to confusion in the conveying sequence and positioning of a series of subsequent buttons. This not only reduces processing efficiency but may also affect the accuracy and consistency of the laser engraved pattern due to inaccurate positioning, increasing the scrap rate.

[0004] Therefore, there is a need to provide a button laser engraving device to solve the problem of the lack of flexible movement control in existing button laser engraving devices. Summary of the Invention

[0005] The main objective of this invention is to provide a button laser engraving device, which aims to solve the technical problems mentioned in the background section.

[0006] The present invention adopts the following technical solution: A button laser engraving device, comprising: A first positioning component and a second positioning component are arranged along a first direction. The second positioning component is disposed on one side of the first positioning component. The first positioning component includes a positioning block, and the upper end surface of the positioning block is formed with a positioning groove for accommodating a button. The second positioning component includes a positioning clamp, and the upper end surface of the positioning clamp is formed with a fixing groove of variable diameter. A laser engraving head is disposed above the positioning clamp and faces the fixing groove. The conveying mechanism includes a feeding nozzle disposed above the positioning block. The top of the feeding nozzle is connected to the drive end of a rotary motor. A drive assembly is disposed on one side of the rotary motor. The drive assembly is used to drive the rotary motor to move along a first direction and a second direction to deliver the button from the positioning slot to the fixing slot for laser engraving.

[0007] Furthermore, the conveying mechanism also includes a bracket, which is disposed on one side of the first positioning component, and a support plate is connected to the side of the bracket closest to the first positioning component; The driving assembly includes a driving arm extending along a first direction. A first end of the driving arm is fixedly connected to the rotary motor, and a transmission arm is rotatably connected to a second end of the driving arm. A servo motor is provided on the side of the support plate opposite to the first positioning assembly. The driving end of the servo motor rotates around a third direction, and the driving end of the servo motor is fixedly connected to the transmission arm to drive the driving arm to transport the button in the positioning slot to the fixing slot.

[0008] Furthermore, the driving component also includes a first slide rail distributed along a first direction and a second slide rail distributed along a second direction. The first slide rail is disposed on the side of the bracket near the first positioning component. A first slider is slidably connected to the first slide rail. A second slider is fixedly disposed on the side of the first slider near the first positioning component. The second slider is slidably connected to the second slide rail. The bottom end of the second slide rail is fixedly connected to the drive arm, and the top end of the second slide rail is rotatably connected to the transmission arm.

[0009] Furthermore, a guide block is provided on the side of the support plate near the second slide rail, and an inverted U-shaped guide groove is provided on one end face of the guide block near the second slide rail. The second slide rail is provided with a guide post that is slidably connected to the guide groove, and the transmission arm is provided with an oblong hole corresponding to the guide post. When the transmission arm rotates, the guide post is driven to slide along the guide groove, causing the feeding nozzle to convey the button along a preset trajectory.

[0010] Furthermore, it also includes a feeding assembly, which includes a vibratory feeder. The output end of the vibratory feeder is connected to a feeding channel distributed along a first direction. The end of the feeding channel away from the vibratory feeder abuts against the positioning block. The positioning block has an installation opening on one side along a third direction that extends through to the positioning groove. A pushing cylinder is provided on one side of the installation opening. The output shaft of the pushing cylinder faces the installation opening to push the button of the feeding channel into the positioning groove.

[0011] Furthermore, the upper end cover of the feeding channel is provided with a limiting plate, and an adjusting pad is detachably connected between the limiting plate and the feeding channel, so that the distance between the limiting plate and the feeding channel is adjustable.

[0012] Furthermore, the second positioning component also includes a gripper cylinder, which is provided with a plurality of coaxial grippers. The positioning clamp is fixedly connected to the grippers. Each of the positioning clamps is provided with an arc-shaped bearing portion. The bearing portion is recessed and provided with a bearing groove. The plurality of bearing grooves form the fixing groove.

[0013] Furthermore, it also includes an unloading assembly, which includes a rotary clamping cylinder disposed on the side of the second positioning assembly away from the first positioning assembly. The drive end of the rotary clamping cylinder is connected to an unloading arm, and one end of the unloading arm is connected to an unloading suction nozzle. An auxiliary positioning fork is connected to one side of the rotary clamping cylinder. The auxiliary positioning fork forms an auxiliary groove. Along the first direction, the auxiliary groove is located on one side of the fixed groove. When the unloading arm falls into the auxiliary groove, the unloading suction nozzle is located directly above the fixed groove.

[0014] Furthermore, a discharge hopper is provided on one side of the rotary clamping cylinder. The discharge hopper is inclined and has an open end. A receiving bin is provided below the discharge hopper, and the receiving bin corresponds to the open end of the discharge hopper.

[0015] Beneficial effects: In this invention, precise and flexible button positioning is achieved through the first and second positioning components. The positioning block and positioning groove effectively fix the button's position, ensuring it does not shift during laser engraving. The variable-diameter fixing groove and positioning clamp of the second positioning component further enhance adaptability to buttons of different sizes, effectively improving compatibility with buttons of different specifications, while also ensuring the accuracy and consistency of the laser-engraved pattern. Furthermore, the conveying mechanism, through the cooperation of the feeding nozzle and the rotary motor, is driven by the drive component to move the rotary motor and its feeding nozzle along predetermined trajectories in the first and second directions. This enables flexible and independent button handling, ensuring the stability of individual buttons during transport and avoiding jamming or positional deviations caused by simple linear handling, which could lead to processing interruptions or errors. This improves the quality consistency and production efficiency of the laser-engraved button patterns. Attached Figure Description

[0022] Reference Figures 1 to 5 The present invention proposes a button laser engraving device, comprising: a first positioning component 1 and a second positioning component 2. Along a first direction, the second positioning component 2 is disposed on one side of the first positioning component 1. The first positioning component 1 includes a positioning block 110, the upper end surface of which forms a positioning groove 111 for accommodating a button. The second positioning component 2 includes a positioning clamp 210, the upper end surface of which forms a fixing groove 211 with a variable diameter. A laser engraving head 3 is disposed above the positioning clamp 210 and faces the fixing groove 211. The conveying mechanism 4 includes a feeding nozzle 41 disposed above the positioning block 110. The top end of the feeding nozzle 41 is connected to the drive end of the rotary motor 42. A drive assembly 45 is disposed on one side of the rotary motor 42. The drive assembly 45 is used to drive the rotary motor 42 to move along a first direction and a second direction to send the button from the positioning groove 111 to the fixing groove 211 for laser engraving.

[0023] In the above embodiments, the coordinated operation of the first positioning component 1, the second positioning component 2, and the conveying mechanism 4 achieves precise positioning and efficient conveying of the button, thereby ensuring the consistency of laser engraving pattern quality and production efficiency. The first positioning component 1 includes a support member and a rectangular positioning block 110 above it. The upper surface of the positioning block 110 is machined with multiple circular positioning grooves 111. The size of the grooves matches the shape of the button to be processed, and the groove depth is approximately the thickness of the button, ensuring that the button can be stably fitted without shifting when placed. The positioning block 110 is made of high-strength aluminum alloy, and the surface is precision polished to reduce friction, facilitating the insertion and removal of the button. The second positioning component 2 is located on the left side of the first positioning component 1 along the first direction (horizontal X-axis direction), and includes a set of positioning clamps 210. The upper surface of the positioning clamps 210 is provided with a fixing groove 211 with an adjustable diameter to accommodate buttons of different specifications. The inner wall of the fixing groove 211 can be made of soft silicone material to increase friction, further fix the button, and prevent position shift caused by laser vibration during laser engraving. A high-precision laser head 3 is installed above the positioning clamp 210. It can move up and down along the Z-axis by a motor and is equipped with a focusing lens to ensure that the laser beam is accurately applied to the button surface to engrave a clear and consistent pattern.

[0024] The feeding nozzle 41 of the conveying mechanism 4 adopts a vacuum adsorption structure with a flexible rubber suction cup at the bottom, which can adapt to the surface of buttons of different shapes and ensure the stability of adsorption. The feeding nozzle 41 is fixedly connected to the drive end of the rotary motor 42 via a connecting rod. The rotary motor 42 is a stepper motor, which can achieve precise angle control of 0.1° to adjust the posture of the nozzle during the conveying process, so as to ensure that the button maintains the correct orientation during the transfer from the positioning groove 111 to the fixing groove 211. The rotary motor 42 moves along the first direction (horizontal X-axis direction) and the second direction (vertical Z-axis direction) through a drive component 45. The drive component 45 can be configured to include a linear guide rail and a servo motor 453, and the guide rail adopts a ball screw structure. During the conveying process, the drive component 45 controls the rotary motor 42 and the nozzle according to a preset trajectory, first rising along the Z-axis to disengage from the positioning groove 111, then moving horizontally along the X-axis to above the fixing groove 211, and finally descending along the Z-axis to accurately place the button into the fixing groove 211. The entire handling process avoids jamming or collisions that may be caused by simple linear movement, ensuring smooth and continuous handling. This device, through precise positioning of the positioning groove 111 and the fixing groove 211, combined with the compatibility of the variable diameter fixing groove 211 with buttons of different sizes, and the efficient and stable operation of the handling mechanism 4, effectively improves the accuracy and efficiency of laser engraving. It is suitable for mass production of buttons of various specifications, significantly reducing the occurrence of processing interruptions and pattern deviations.

[0025] refer to Figure 1 and Figure 2In one embodiment, the conveying mechanism 4 further includes a bracket 43, which is disposed on one side of the first positioning component 1, and a support plate 44 is connected to the side of the bracket 43 near the first positioning component 1. The drive assembly 45 includes a drive arm 451 extending along a first direction. The first end of the drive arm 451 is fixedly connected to the rotary motor 42, and the second end of the drive arm 451 is rotatably connected to a transmission arm 452. A servo motor 453 is provided on the side of the support plate 44 opposite to the first positioning assembly 1. The drive end of the servo motor 453 rotates around a third direction, and the drive end of the servo motor 453 is fixedly connected to the transmission arm 452 to drive the drive arm 451 to transport the button in the positioning groove 111 to the fixing groove 211.

[0026] In the above embodiment, the bracket 43 is installed on the side of the first positioning component 1, and the support plate 44 is connected to the side of the bracket 43 closest to the first positioning component 1. The support plate 44 provides stable support for the entire drive assembly 45, ensuring that no unnecessary vibration or displacement occurs during operation, further improving the stability of the device. The drive assembly 45 adopts a linkage structure of drive arm 451 and transmission arm 452. The first end of the drive arm 451 is fixedly connected to the rotary motor 42. The function of the rotary motor 42 is to drive the entire feeding nozzle 41 to move along the first direction and the second direction through the drive arm 451. The fixed part of the rotary motor 42 is connected to the drive arm 451, and the other end of the drive arm 451 is rotatably connected to the transmission arm 452, realizing the process of the feeding nozzle 41 moving from the positioning groove 111 to the fixed groove 211.

[0027] Furthermore, a servo motor 453 is installed on the side of the support plate 44 opposite to the first positioning component 1. The drive end of the servo motor 453 is connected to the transmission arm 452 via a reducer. The servo motor 453 is responsible for advancing the drive arm 451 by adjusting the angle of the transmission arm 452, further realizing the feeding of the feeding nozzle 41 along the first and second directions. This allows the feeding nozzle 41 to smoothly convey buttons along the set trajectory, thereby avoiding the risk of deviating from the path and improving the accuracy and efficiency of the device.

[0028] In one example, the drive assembly 45 further includes a first slide rail 454 distributed along a first direction and a second slide rail 455 distributed along a second direction. The first slide rail 454 is disposed on the side of the bracket 43 near the first positioning assembly 1. A first slider 456 is slidably connected to the first slide rail 454. A second slider 457 is fixedly disposed on the side of the first slider 456 near the first positioning assembly 1. The second slider 457 is slidably connected to the second slide rail 455. The bottom end of the second slide rail 455 is fixedly connected to the drive arm 451, and the top end of the second slide rail 455 is rotatably connected to the transmission arm 452.

[0029] In the above embodiment, the drive assembly 45 includes a first slide rail 454 arranged along a first direction and a second slide rail 455 arranged along a second direction. The first slide rail 454 is disposed on the side of the bracket 43 near the first positioning assembly 1 and is slidably connected to the first slider 456. The first slider 456 is fixedly connected to the second slider 457, and the second slider 457 is slidably engaged with the second slide rail 455. That is, the sliding of the first slider 456 along the first direction combined with the sliding of the second slide rail 455 along the second direction enables the feeding nozzle 41 to move smoothly in both directions along a predetermined trajectory. The bottom end of the second slide rail 455 is fixedly connected to the drive arm 451, and the top end is rotatably connected to the transmission arm 452, allowing the drive arm 451 to be precisely controlled in both horizontal and vertical directions.

[0030] Specifically, the feeding nozzle 41 moves in the X-axis direction via the first slide rail 454, and then the Z-axis direction is precisely controlled via the second slide rail 455. This allows the feeding nozzle 41 to not only move horizontally in the X-axis direction, but also to perform fine lifting control in the Z-axis direction, ensuring that the button is accurately transferred from the positioning slot 111 to the fixing slot 211. This avoids vibration or instability that may occur in traditional systems, further improving the stability of the system. Moreover, it can maintain good accuracy and efficiency under high-speed or frequent operation conditions, significantly improving the stability of the production process.

[0031] refer to Figure 2 In one example, the support plate 44 is provided with a guide block 458 on the side near the second slide rail 455. The guide block 458 is provided with an inverted U-shaped guide groove 458a on one end face near the second slide rail 455. The second slide rail 455 is provided with a guide post 459 that is slidably connected to the guide groove 458a. The transmission arm 452 is provided with an oblong hole 452a corresponding to the guide post 459. When the transmission arm 452 rotates, the guide post 459 is driven to slide along the guide groove 458a, so that the feeding nozzle 41 conveys the button along a preset trajectory.

[0032] In the above embodiment, the guide block 458 and guide post 459 enable the feeding nozzle 41 to move precisely along a predetermined path. Specifically, a guide block 458 is provided on the side of the support plate 44 near the second slide rail 455. The guide block 458 may consist of two symmetrical discontinuous blocks, with an inverted U-shaped guide groove 458a formed on its end face. A guide post 459 is slidably fitted within the guide groove 458a, and the guide post 459 is fixedly connected to the second slide rail 455. At the position of the transmission arm 452 corresponding to the guide post 459, an oblong hole 452a is provided. The guide post 459 passes through the oblong hole 452a and can slide within the guide groove 458a.

[0033] When the transmission arm 452 rotates due to the drive of the servo motor 453, the transmission arm 452 drives the guide post 459 to slide along the guide groove 458a. The guide groove 458a restricts the movement trajectory to a preset path, ensuring that the feeding nozzle 41 can move precisely along the set trajectory. This allows the button to maintain the correct orientation and position during the transfer from the positioning groove 111 to the fixing groove 211. The combination of the guide post 459 and the oblong hole 452a avoids transmission interference of the transmission arm 452. Matching the non-circular inverted U-shaped guide groove 458a not only optimizes the path of the feeding nozzle 41 but also effectively avoids any errors or jamming caused by path deviation.

[0034] refer to Figures 1 to 5 In one example, a feeding assembly is also included, which includes a vibratory feeder 5. The output end of the vibratory feeder 5 is connected to a feeding channel 6 distributed along a first direction. The end of the feeding channel 6 away from the vibratory feeder 5 abuts against the positioning block 110. The positioning block 110 has an installation opening 112 extending through to the positioning groove 111 on one side along a third direction. A pushing cylinder 7 is provided on one side of the installation opening 112. The output shaft of the pushing cylinder 7 faces the installation opening 112 to push the button of the feeding channel 6 into the positioning groove 111.

[0035] In the above embodiment, the feeding assembly automatically transports the buttons from a loose state to a positioned state. The feeding assembly includes a vibratory feeder 5, a feeding channel 6, and a pushing cylinder 7. The vibratory feeder 5 carries and vibrates multiple loose buttons, causing them to automatically arrange and be oriented for output. The output end of the vibratory feeder 5 is connected to a feeding channel 6 extending along a first direction (X-axis direction). One end of the feeding channel 6 is connected to the outlet of the vibratory feeder 5 to receive the arranged buttons in the vibratory feeder 5 and push them one by one to the positioning area. The other end of the feeding channel 6, i.e., the end away from the vibratory feeder 5, is fixedly abutted against the positioning block 110 in the first positioning assembly 1. To achieve precise pushing of the buttons from the feeding channel 6 into the positioning groove 111, the positioning block 110 is provided with an installation opening 112 extending through to the positioning groove 111 on one side along a third direction (horizontal Y-axis direction) for the insertion of the pushing mechanism. A pusher cylinder 7 is provided on one side of the mounting opening 112. The pusher cylinder 7 is fixedly installed by a flange or bracket 43. The output shaft of the cylinder faces the mounting opening 112 and is aligned with the button at the outlet of the feeding channel 6. During operation, the pusher cylinder 7 operates periodically according to the control program, pushing the button in the feeding channel 6 along the end of the channel into the positioning groove 111 of the positioning block 110, thereby realizing the quantitative feeding of a single button.

[0036] refer to Figure 3 In one example, the upper end face of the feeding channel 6 is covered with a limiting plate 8, and an adjusting pad 9 is detachably connected between the limiting plate 8 and the feeding channel 6, so that the distance between the limiting plate 8 and the feeding channel 6 is adjustable.

[0037] In the above embodiment, a limiting plate 8 structure is provided on the upper end face of the feeding channel 6, and the height space within the channel is controlled by an adjustable component. Specifically, a limiting plate 8 is provided on the upper cover of the feeding channel 6, and the limiting plate 8 and the feeding channel 6 are detachably connected by screws or quick-release buckles, which facilitates cleaning and replacement. In order to adjust the vertical distance between the limiting plate 8 and the feeding channel 6, an adjusting pad 9 is provided at their connection. The adjusting pad 9 can be a modular structural component of different thicknesses. The user can control the distance between the limiting plate 8 and the feeding channel 6 by changing the pad of different thicknesses according to the required button thickness. During the feeding process, the limiting plate 8 restricts the vertical direction of the button, preventing the button from becoming unstable such as standing sideways or tilting during vibration or pushing, thereby ensuring that each button enters the positioning groove 111 in the correct posture.

[0038] refer to Figure 3In one embodiment, the second positioning component 2 further includes a gripper cylinder 220, the gripper cylinder 220 is provided with a plurality of coaxial grippers, the positioning clamp 210 is fixedly connected to the grippers, the plurality of positioning clamps 210 are each provided with an arc-shaped bearing portion 212, the bearing portion 212 is recessed and provided with a bearing groove 213, the plurality of bearing grooves 213 form the fixing groove 211.

[0039] In the above embodiment, the second positioning component 2 is equipped with a gripper cylinder 220 and its corresponding structure to achieve precise gripping and stable fixation of the button. The gripper cylinder 220 has several coaxial grippers, which can open and close synchronously through the drive of the cylinder. The positioning clamp 210 and the grippers work together through a fixed connection, so that the grippers can accurately grip and release the button when needed. Each positioning clamp 210 cooperates with the inner bearing groove 213 through a curved support part 212. The support part 212 is arc-shaped, so that the button can be placed stably in it, avoiding its position displacement due to vibration or external force during laser engraving. Multiple bearing grooves 213 are combined into a fixing groove 211, forming support and fixation for the button, so that it is not affected by external interference during processing. The concave structure of the bearing groove 213 and the annular structure of the support part 212 can make buttons of different sizes evenly stressed, ensuring the accuracy and consistency of the pattern during laser engraving.

[0040] In one embodiment, the system further includes an unloading assembly 10, which includes a rotary clamping cylinder 101. The rotary clamping cylinder 101 is disposed on the side of the second positioning assembly 2 away from the first positioning assembly 1. The driving end of the rotary clamping cylinder 101 is connected to an unloading arm 102, and one end of the unloading arm 102 is connected to an unloading suction nozzle 103. An auxiliary positioning fork 104 is connected to one side of the rotary clamping cylinder 101. The auxiliary positioning fork 104 forms an auxiliary groove 104a. Along the first direction, the auxiliary groove 104a is located on one side of the fixed groove 211. When the unloading arm 102 falls into the auxiliary groove 104a, the unloading suction nozzle 103 is located directly above the fixed groove 211.

[0041] In the above embodiment, the combination structure of the rotary clamping cylinder 101 and the unloading arm 102 in the unloading assembly 10 enables the transfer of buttons from the fixing groove 211 of the laser engraving device to the unloading area. The rotary clamping cylinder 101 is installed on the side of the second positioning assembly 2 away from the first positioning assembly 1. The drive end of the rotary clamping cylinder 101 can extend, retract, and rotate, and is mechanically connected to the unloading arm 102. The end of the unloading arm 102 is equipped with an unloading suction nozzle 103, which is used to pick up and transport the laser-engraved buttons. The main function of the rotary clamping cylinder 101 is to control the movement of the unloading arm 102 in three directions, ensuring that the unloading suction nozzle 103 can be accurately aligned with the fixing groove 211, avoiding the buttons from falling off or being misaligned. The unloading arm 102, in conjunction with the action of the rotary clamping cylinder 101, can accurately position the suction nozzle directly above the fixing groove 211, and then descend from this position to pick up and transfer the buttons. To ensure the accuracy of material suction during the unloading process, an auxiliary positioning fork 104 is also provided on one side of the rotary clamping cylinder 101. The auxiliary positioning fork 104 is provided with an auxiliary groove 104a, which is set next to the fixed groove 211 along the first direction, that is, set on the left side of the fixed groove 211. This ensures that the suction nozzle can always be aligned with the fixed groove 211 during the movement of the unloading arm 102, accurately controlling the unloading process and ensuring that each button is stably and efficiently transferred to the unloading area after processing, thereby improving the efficiency of the overall production line.

[0042] In one embodiment, a discharge hopper 11 is provided on one side of the rotary clamping cylinder 101. The discharge hopper 11 is inclined and one end of the discharge hopper 11 is open. A receiving bin 12 is provided below the discharge hopper 11, and the receiving bin 12 corresponds to the open end of the discharge hopper 11.

[0043] In the above embodiment, the unloading hopper 11 and the receiving bin 12 enable the processed buttons to enter the automatic receiving process. The unloading hopper 11 is installed on one side of the rotary clamping cylinder 101. The unloading hopper 11 is inclined, with its lower end being an open end for discharging buttons taken from the unloading suction nozzle 103. The inclined design of the unloading hopper 11 allows the buttons to slide smoothly into it under gravity, reducing potential jamming or material accumulation during operation. The receiving bin 12 is located below the unloading hopper 11 to receive and store the buttons discharged from it. The receiving bin 12 is positioned to align with the open end of the unloading hopper 11, effectively accommodating the unloaded buttons and ensuring smooth stacking, preventing confusion or scattering. The entire unloading process is automated, reducing manual intervention and improving production efficiency. It effectively ensures that the processed buttons can flow into the receiving bin 12 in an orderly manner, making the entire processing and unloading process more stable and efficient. It is suitable for continuously and stably handling high-volume button laser engraving processing tasks in large-scale production environments.
