Description

Technical Field

[0001] This utility model relates to the field of laser technology, and more specifically, to a dual-station button laser engraving device for precise delivery. Background Technology

[0002] Buttons, as an indispensable standard accessory in the light industry, are increasingly in demand for patterned and labeled designs. In industries such as clothing and bags, to enhance product aesthetics and brand recognition, more and more manufacturers are choosing laser engraving technology to mark button surfaces. Laser engraving offers advantages such as non-contact processing, high precision, and a high degree of automation, making it particularly effective in mass production. To improve processing efficiency and adapt to the continuous operation requirements of buttons of various specifications, dual-station laser engraving equipment is gradually replacing traditional single-station structures, becoming one of the mainstream development trends in the industry. Especially in production environments with fast material loading and high production line takt time, there is an urgent need for dual-station equipment with rapid material loading and precise handling mechanisms to meet the requirements of efficient and stable laser processing.

[0003] Currently common dual-station button laser engraving devices typically use vibratory feeding components (such as direct vibratory feeders) for rapid material feeding. However, the vibratory feeding module is usually installed on the same support structure as the conveying module. During actual operation, the mechanical residual vibration generated by the vibratory feeder will be transmitted to the conveying module. The conveying component is easily affected by vibration during the gripping and positioning process, especially when the material volume is large and the feeding frequency is high. This can lead to deviations in the conveying path and imbalances in posture. In severe cases, it can cause the buttons to fail to be accurately fed into the fixed station, thereby affecting the overall processing accuracy and the stability of the equipment cycle time.

[0004] Therefore, there is a need to provide a precise dual-station button laser engraving device to solve the problem that existing dual-station button laser engraving devices are susceptible to mechanical residual vibration, which can lead to deviations in the transport path and imbalances in posture. Utility Model Content

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

[0006] The present invention adopts the following technical solution: A precision conveying dual-station button laser engraving device, comprising: A first support component is provided, and a vibratory feeding component is installed on the upper surface of the first support component. A fixing component for fixing the button is provided on one side of the end of the vibratory feeding component. A laser engraving head facing the fixing component is provided above the fixing component. The second support assembly includes a support plate disposed above the first support assembly. The support plate has clearance holes corresponding to the vibrating feeding assembly and the fixing assembly, and the upper end surface of the support plate is provided with two conveying assemblies symmetrically distributed on both sides of the vibrating feeding assembly. The conveying assembly is used to move the button from the end of the vibrating feeding assembly to the fixing assembly, and the support plate is separate from the first support assembly.

[0007] Furthermore, the first support component includes a laser engraving control box, the upper surface of which is covered with a substrate, and the vibration feeding component and the fixing component are both disposed on the upper surface of the substrate.

[0008] Furthermore, the second support component also includes a bracket, which is fixedly disposed at the bottom end of the support plate and distributed on opposite sides of the laser engraving control box.

[0009] Furthermore, the vibratory feeding assembly includes a vibratory plate and a feeding track connected to the output end of the vibratory plate. The end of the feeding track is correspondingly arranged with the fixing assembly, and a linear vibratory feeder is provided at the bottom end of the feeding track. The linear vibratory feeder is installed on the upper surface of the substrate.

[0010] Furthermore, a circuit control box is provided below the vibratory feeder, and a number of fasteners are connected to the bottom end of the vibratory feeder. The fasteners include a circular sleeve portion and a connecting portion extending to one side of the sleeve portion. The sleeve portion is sleeved on the bottom end of the vibratory feeder, and the connecting portion is fixedly connected to the circuit control box. The number of fasteners is arranged around the central axis of the vibratory feeder.

[0011] Furthermore, the fixing component includes two symmetrically arranged gripper cylinders. Along the extending direction of the vibrating feeding component, the two gripper cylinders correspond to the two conveying components respectively. The upper end face of the gripper cylinder is fixedly connected with a plurality of coaxially arranged fixing claws, and the fixing claws form a clamping groove for clamping the button.

[0012] Furthermore, the bracket includes a square support column and a circular support tube, the support column and the support tube are respectively arranged on opposite sides of the laser engraving control box, and a reinforcing tube is connected between the support column and the support tube. The bottom ends of the support column and the support tube are provided with feet.

[0013] Furthermore, the conveying assembly includes a support base, which is fixedly disposed on the upper end surface of the support plate. The support base is equipped with a drive component and a vacuum generator. The drive end of the drive component is connected to a conveying suction cup. The vacuum generator is connected to the conveying suction cup. The drive component is used to drive the conveying suction cup to convey the button from the end of the vibrating feeding assembly to the fixed assembly.

[0014] Beneficial effects: This invention achieves rapid feeding and precise processing by arranging a vibratory feeding component on a first support component and setting a fixing component and a corresponding laser engraving head at its end. An independent second support component is positioned above the first support component. The support plate has clearance holes, and two sets of transport components are symmetrically arranged on its upper surface to accurately transport the buttons from the feeding end to the fixing component. By placing the transport components and the vibratory feeding component on different structural support units, they are effectively isolated structurally, thus avoiding interference from residual vibrations generated during vibratory feeding on the transport components. This ensures the stability of the transport path and the consistency of the positioning posture, effectively guaranteeing the precise alignment of the buttons during transport to the laser engraving station, improving overall processing accuracy, especially in dual-station high-frequency operations, effectively avoiding transport errors and processing cycle fluctuations caused by vibration interference.

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, a direct connection, or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0020] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them.

[0021] Reference Figures 1 to 3 This utility model proposes a dual-station button laser engraving device for precise delivery, comprising: a first support component 1, a vibrating feeding component 3 installed on the upper end surface of the first support component 1, a fixing component 4 for fixing buttons provided on one side of the end of the vibrating feeding component 3, and a laser engraving head facing the fixing component 4 provided above the fixing component 4. The second support component 2 includes a support plate 21 disposed above the first support component 1. The support plate 21 has clearance holes 211 corresponding to the vibrating feeding component 3 and the fixing component 4. The upper end surface of the support plate 21 is provided with two conveying components 5 symmetrically distributed on both sides of the vibrating feeding component 3. The conveying component 5 is used to convey the button from the end of the vibrating feeding component 3 to the fixing component 4, and the support plate 21 is separated from the first support component 1.

[0022] In the above embodiment, a vibratory feeding component 3 is installed on the upper surface of the first support component 1. This feeding component preferably uses a linear vibratory feeder 33 as an auxiliary feeding device to meet the rapid feeding needs of large batches of buttons, featuring fast feeding rhythm, neat arrangement, and controllable feeding direction. A fixing component 4 is provided on the side of the end of the vibratory feeding component 3 to accurately position the buttons and prevent them from shifting during receiving and handling. A laser engraving head is provided directly above the fixing component 4 for high-precision laser engraving of the buttons in a fixed state, achieving efficient engraving of patterns, logos, or codes. To ensure the stability and accuracy of the handling process, the entire handling process does not rely on the first support component 1 for structural support.

[0023] The second support component 2 is set independently of the first support component 1. Its structure is a support plate 21, located above the first support component 1, and is constructed through a height-isolation method, not rigidly connected to the first support component 1. The support plate 21 has multiple clearance holes 211, corresponding to the positions of the vibrating feeding component 3 and the fixing component 4 on the first support component 1, allowing the transport mechanism to pass through the support plate 21 without interfering with the structure below. Two transport components 5 are set on the upper surface of the support plate 21, symmetrically arranged on the left and right sides of the vibrating feeding component 3. Each transport component 5 is responsible for transporting a button from the end of a feeding channel to the fixing component 4 below. The transport components 5 are fixed to the support plate 21, which is separate from the vibration source, and are not affected by the mechanical residual vibration generated during the operation of the direct vibration feeder 33 below. This ensures the stability of the gripping path and the consistency of the end effector's posture during transport, significantly reducing the transport error rate and improving the consistency of the button's spatial posture during transport, providing a precise alignment basis for laser processing.

[0024] In summary, the feeding and processing functions are concentrated in the lower support structure, while the handling function is implemented independently in the upper structure. Through physical separation, the vibration propagation path is effectively avoided, improving the operational stability and cycle control capability of the equipment during high-frequency dual-station operation.

[0025] refer to Figure 3In one embodiment, the first support component 1 includes a laser engraving control box 11, the upper surface of which is covered with a substrate 12, and the vibration feeding component 3 and the fixing component 4 are both disposed on the upper surface of the substrate 12.

[0026] In the above embodiment, in the first support component 1, the laser engraving control box 11 serves as the bottom support box and further integrates a control and operation module for driving and controlling the laser head. To ensure good structural support and functional coordination of the entire feeding and processing unit, a base plate 12 is laid on the upper surface of the laser engraving control box 11, serving as a direct support platform for the feeding module and the fixing component 4. The vibration feeding component 3 is mounted on the upper surface of the base plate 12, which, on the one hand, utilizes the rigid foundation of the base plate 12 to ensure stable operation of the feeding system, and on the other hand, facilitates subsequent structural integration and debugging.

[0027] Meanwhile, the vibration feeding component 3 and the fixing component 4 are both set on the upper surface of the substrate 12, and the laser head is set on one side of the substrate 12 and installed on the top surface of the laser control box 11.

[0028] refer to Figure 1 In one example, the second support component 2 further includes a bracket 22, which is fixedly disposed at the bottom end of the support plate 21 and distributed on opposite sides of the laser engraving control box 11.

[0029] In the above embodiment, the second support component 2 includes not only the support plate 21 but also several brackets 22, achieving structural stability and independent operation of the second support component 2. The brackets 22 are column-shaped structures, fixedly installed at the bottom of the support plate 21, and distributed on opposite sides of the laser engraving control box 11. This allows the second support component 2 to be self-supported and installed without relying on the first support component 1, thus forming a handling operation platform completely independent of the lower structure. The brackets 22 support ensure that the clearance holes 211 on the support plate 21 accurately correspond to the positions of the vibrating feeding component 3 and the fixing component 4 in the first support component 1, ensuring that the handling component 5 does not interfere with each other during vertical movement. This avoids the transmission of any direct structural loading or vibration from the lower vibration source during operation, fundamentally blocking the vibration influence path.

[0030] In one embodiment, the vibratory feeding assembly 3 includes a vibratory plate 31 and a feeding track 32 connected to the output end of the vibratory plate 31. The end of the feeding track 32 is correspondingly disposed with the fixing assembly 4, and a linear vibratory feeder 33 is disposed at the bottom end of the feeding track 32. The linear vibratory feeder 33 is mounted on the upper surface of the substrate 12.

[0031] In the above embodiment, the vibratory feeding assembly 3 includes a circular vibratory plate 31 for storing a large number of raw bulk buttons. Through its own vibration, the buttons are arranged in an orderly manner to the discharge port and then enter the feeding track 32 connected to its output end. The feeding track 32 extends forward along a linear path, and its end is set to correspond to the installation position of the fixing assembly 4, realizing a fully automated transmission process of buttons from vibration arrangement to fixed positioning.

[0032] Furthermore, to meet the demands of high-volume, high-cycle production, a vertical vibration feeder 33 is installed at the bottom of the feeding track 32, mounted on the upper surface of the substrate 12, serving as one of the core power sources for the entire feeding system. The vertical vibration feeder 33 utilizes electromagnetic vibration to propel the buttons along the track, exhibiting high feeding stability and strong controllability, making it particularly suitable for dual-station systems with high cycle time requirements. The feeding structure is attached to the first support component 1, and all its vibrations and pushing behavior are confined within this structure, preventing transmission to the conveying mechanism of the second support component 2, thus ensuring the accuracy and repeatability of the conveying path.

[0033] refer to Figure 1 and Figure 2 In one embodiment, a circuit control box 6 is provided below the vibratory feeder 31, and a plurality of fasteners 7 are connected to the bottom end of the vibratory feeder 31. The fasteners 7 include a circular sleeve portion 71 and a connecting portion 72 extending to one side of the sleeve portion 71. The sleeve portion 71 is sleeved on the bottom end of the vibratory feeder 31, and the connecting portion 72 is fixedly connected to the circuit control box 6. The plurality of fasteners 7 are arranged around the central axis of the vibratory feeder 31.

[0034] In the above embodiment, a circuit control box 6 is provided below the vibratory feeder 31 to enhance the structural stability and controllability of vibration transmission of the vibratory feeder 31, and also to provide support for the vibratory feeder 31. This box is mainly used to provide drive control circuits and power management for the vibratory feeder 31 and its downstream structures (such as the direct vibration feeder 33). To achieve a secure connection between the vibratory feeder 31 and the box, the bottom of the vibratory feeder 31 is mounted on the circuit control box 6 using several fasteners 7. Each fastener 7 includes a circular sleeve portion 71 and an integrally extended connecting portion 72. The sleeve portion 71 directly covers the corresponding flange or connecting post at the bottom of the vibratory feeder 31, achieving a stable fit through a sleeve-type contact method; while the connecting portion 72 is fixedly connected to the outer shell of the circuit control box 6 using screws or bolts. Multiple fasteners 7 are evenly distributed around the central axis of the vibratory feeder 31, ensuring that the entire vibratory feeder 31 is subjected to balanced forces during operation, the vibration transmission path is controllable, eccentric operation is avoided, and the efficiency and stability of vibratory feeding are improved.

[0035] In one embodiment, the fixing component 4 includes two symmetrically arranged gripper cylinders 41. Along the extending direction of the vibrating feeding component 3, the two gripper cylinders 41 correspond to the two conveying components 5 respectively. The upper end face of the gripper cylinder 41 is fixedly connected with a plurality of coaxially arranged fixing claws 42. The fixing claws 42 form a clamping groove for clamping buttons.

[0036] In the above embodiment, the fixing component 4 specifically consists of two gripper cylinders 41, arranged symmetrically on both sides of the end of the vibrating feeding component 3, and arranged along the extension direction of the feeding track 32 to ensure a one-to-one correspondence with the conveying paths of the two conveying components 5 above. Each gripper cylinder 41 has several coaxially arranged fixing claws 42 mounted on its upper end. Each fixing claw 42 has a clamping groove for holding the button, the size of which matches the outer diameter of the button, enabling precise clamping and positioning. During operation, after the conveying component 5 places the button in the area of ​​the fixing component 4, the gripper cylinder 41 drives the fixing claws 42 to retract and clamp the button, achieving a fast and stable positioning process. Subsequently, the laser head can accurately perform the processing task.

[0037] refer to Figure 3 In one embodiment, the bracket 22 includes a square support column 221 and a circular support tube 222. The support column 221 and the support tube 222 are respectively disposed on opposite sides of the laser engraving control box 11, and a reinforcing tube 223 is connected between the support column 221 and the support tube 222. The bottom ends of the support column 221 and the support tube 222 are provided with feet 23.

[0038] In the above embodiment, the bracket 22 adopts a multi-form combination structure, including a square support column 221 and a circular support tube 222, which are respectively installed on the left and right sides of the laser engraving control box 11. Furthermore, the cross-sectional area of ​​the support tube 222 is smaller than that of the square support column 221. It is installed between the circuit control box 6 and the laser engraving control box 11, which allows for a more compact fit between the two boxes. The support column 221 adopts a square tube structure, which has stronger bending rigidity and is used to bear the main mass load on the support plate 21. The support tube 222 provides auxiliary support and is connected to the support column 221 through a reinforcing tube 223 to form a lateral stability structure, effectively preventing structural torsion caused by vibration or device operation. The reinforcing tube 223 can be connected to the support members at both ends by bolts or welding to form a triangular stable layout, improving the overall impact resistance of the bracket 22. In addition, all support components are equipped with feet 23 at their bottom ends, which can be fixed to the ground to ensure the positional stability of the entire upper structure during operation and prevent the handling mechanism from deviating from its path or failing to adsorb due to slight shaking of the device.

[0039] In one embodiment, the conveying assembly 5 includes a support base 51, which is fixedly disposed on the upper end surface of the support plate 21. The support base 51 is equipped with a drive component 52 and a vacuum generator 53. The drive end of the drive component 52 is connected to a conveying suction cup 54. The vacuum generator 53 is connected to the conveying suction cup 54. The drive component 52 is used to drive the conveying suction cup 54 to convey the button from the end of the vibrating feeding assembly 3 to the fixing assembly 4.

[0040] In the above embodiments, the conveying component 5 specifically includes a support base 51, a drive component 52, a vacuum generator 53, and a conveying suction cup 54. The support base 51 is directly fixed to the upper surface of the support plate 21 of the second support component 2 to support the entire conveying mechanism and ensure installation accuracy. The drive component 52 provided on the support base 51 is preferably an electric slide, a cylinder, or a servo lifting module, and its drive end is connected to the conveying suction cup 54. The conveying suction cup 54 is connected to the vacuum generator 53 through a vacuum pipeline. When the suction cup contacts the button surface, the vacuum generator 53 starts to generate negative pressure, and the suction cup can achieve non-destructive adsorption of the button. The drive component 52 controls the suction cup to move in the vertical and horizontal directions to realize the picking and placing of buttons. The entire conveying action has fast response and high repeatability. In dual-station applications, the two conveying components 5 correspond to the ends of the two feeding channels and the two fixed components 4, respectively, and work together to alternately convey buttons, greatly improving the overall conveying efficiency of the device. By using vacuum adsorption instead of mechanical clamping, mechanical contact with the button surface is reduced. This method is suitable for buttons with special coatings or easily scratched materials. At the same time, the adsorption process is stable and reliable, effectively reducing the failure rate of handling.
