Description

Technical Field

[0001] This utility model relates to the field of titanium chopsticks processing technology, specifically a laser painting machine for processing titanium chopsticks. Background Technology

[0002] Chopsticks are long, thin sticks held between the fingers to pick up food or other items. They can be made of materials such as bamboo, wood, bone, porcelain, metal, and plastic, and come in various shapes, including square and round. They are primarily used as tableware. In the manufacturing process of titanium chopsticks, in addition to basic shaping, laser marking is used to achieve personalized designs such as patterns and logos. Some products also require serration on the gripping end to improve slip resistance. In some cases, marking is done before electroplating or electroplating followed by secondary marking to ensure the durability of the markings.

[0003] The existing patent document with publication number CN209850118U discloses a chopstick laser marking device. It is equipped with a conveying mechanism. A motor drives the first rectangular lead screw and the second rectangular lead screw to rotate, so that the chopsticks move to the laser marking mechanism for marking. After marking, the chopsticks are transported out. The structure is simple, easy to operate, and has two lead screws, which makes it relatively stable. At the same time, a limiting mechanism is set to limit the chopsticks and prevent them from jumping or falling on the rectangular lead screws.

[0004] Although the aforementioned laser marking device for chopsticks can achieve basic marking functions, the chopsticks are prone to stacking and jamming when feeding them, making it difficult to achieve stable feeding one chopstick at a time, which affects processing efficiency; it cannot adapt to the marking requirements of different surface states of titanium chopsticks before and after electroplating.

[0005] Therefore, a laser painting machine for processing titanium chopsticks is proposed. Utility Model Content

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] Please see Figure 1-5 This utility model provides a technical solution: a laser painting machine for processing titanium chopsticks, including a processing table 100, on which are provided a feeding mechanism 200 for feeding titanium chopsticks one by one, a laser color marking machine 300 for laser marking, an electroplating device 400 for immersion electroplating, a marking device 500 for rotating and marking the eating ends of titanium chopsticks, a collection box 600 for collecting titanium chopsticks uniformly, and a robotic arm 700 for transferring titanium chopsticks and cooperating with the laser color marking machine 300 to perform rotational marking; the feeding mechanism 200 includes a storage box 210 located above the processing table 100, with guide positioning columns 220 installed at each of the four corners of the storage box 210, the bottom ends of the guide positioning columns 220 being fixedly connected to the processing table 100, storing... The top of the material box 210 is provided with a feeding port 211. One side of the bottom of the material box 210 is integrally formed with a material storage shell 212 that is adapted to the diameter of the titanium chopsticks. The bottom of the material box 210 is provided with a feeding component 230 for sorting and feeding. Between the feeding component 230 and the material box 210, there is a feeding component 240 for intermittent feeding. The inner wall of the material box 210 is slidably connected with a baffle 250. Two diagonally arranged adjusting guide rods 260 are fixedly connected to one side of the baffle 250. One end of the adjusting guide rod 260 slides through the outside of the material box 210. The surface of the adjusting guide rod 260 is fixedly connected to the material box 210 by locking bolts. The side of the baffle 250 away from the adjusting guide rod 260 forms a receiving cavity for placing titanium chopsticks between it and the material box 210.

[0020] Working principle: Before processing, titanium chopsticks are added into the receiving cavity through the feeding port 211 at the top of the storage box 210. The position of the baffle 250 can be adjusted according to actual needs. By loosening the locking bolt and pulling or pushing the adjusting guide rod 260, the adjusting guide rod 260 drives the baffle 250 to slide in the storage box 210 until the length in the receiving cavity matches the length of the titanium chopsticks. Then the locking bolt can be tightened. Under the guidance of the inclined surface, the titanium chopsticks slide naturally towards the storage shell 212 to avoid accumulation. After processing starts, the servo motor 241 of the feeding component 240 drives the equilateral triangle dial wheel 242 to rotate. The dial wheel 242 intermittently moves the titanium chopsticks at the storage shell 212 through the clearance slot 214 to achieve batch feeding. This ensures that the titanium chopsticks are arranged in sequence in the storage shell 212 and fall into the feeding component 230 below. The drive component 233 of the feeding component 230 drives the double feeding screw 232 to rotate synchronously, smoothly conveying the titanium chopsticks to the gripping range of the robotic arm 700. After the robotic arm 700 picks up the titanium chopsticks, it first moves them to the first laser marking machine 310. The robotic arm 700, in coordination with the marking requirements of the first laser marking machine 310, slowly rotates the chopsticks to complete the marking operation on the unplated area of ​​the titanium chopsticks. After the marking of the unplated area is completed, the robotic arm 700 moves the titanium chopsticks into the electroplating equipment 400 for immersion electroplating. After the electroplating is completed, the robotic arm 700 picks up the titanium chopsticks again and moves them to the second laser marking machine 320 to complete the marking operation on the electroplated area, ensuring a natural connection between the markings in the two areas. After the marking in the electroplating area is completed, the robotic arm 700 transfers the titanium chopsticks to the marking device 500. The marking device 500 performs a rotating marking process on the chopsticks' gripping end to improve their anti-slip performance when gripping food. After the marking process is completed, the titanium chopsticks enter the guide trough 110 from the discharge port of the marking device 500. Guided by the inclined guide trough 110, they automatically slide into the collection box 600 for collection. The entire processing is fully automated, without the need for manual intervention in the material transfer between processes.

[0021] Beneficial effects: The feeding, double marking, electroplating, scoring, collection and transfer components are integrated into the processing table 100 to form an integrated processing system, breaking the limitations of the traditional equipment's dispersed processes, realizing continuous production of titanium chopsticks and improving overall processing efficiency; the adjustable accommodating cavity formed by the baffle 250 and the storage box 210 in the feeding mechanism 200 can adjust the storage space according to actual production needs, adapting to titanium chopsticks of different specifications or batches, improving the equipment's applicability, and eliminating the need to replace the feeding components due to changes in product specifications.

[0022] Specifically, the storage bin 210 has a chopstick disassembly observation port 213 on the side near the baffle 250, and the baffle 250 is a transparent acrylic plate. This design allows for real-time monitoring of the remaining amount of titanium chopsticks in the storage bin 210, facilitating timely replenishment by operators through the replenishment port 211, reducing equipment downtime due to material shortages, and ensuring production continuity. The transparent material also allows for observation of the chopsticks' stacking status within the storage bin 210, enabling timely detection and handling of abnormal stacking, further reducing the risk of feeding jams.

[0023] Specifically, the feeding component 230 includes a bracket 231 installed on the top of the processing table 100 and located below the storage box 210. Two symmetrically arranged feeding screws 232 are rotatably connected to the top of the bracket 231 via bearings. A drive component 233 is installed on the bracket 231 to drive the two feeding screws 232 to rotate synchronously. The drive component 233 is a combination of a motor and a transmission device and is located below the inclined surface. The storage shell 212 is located above the two feeding screws 232. This design provides a stable clamping and conveying force for the titanium chopsticks, preventing them from shifting or jumping during conveying, ensuring the consistency of the gripping position of the subsequent robotic arm 700, and improving the precision of process connections. The position of the drive component 233 avoids occupying space in the feeding area and is located away from the unloading path, preventing the operation of the drive component 233 from interfering with the unloading of the titanium chopsticks.

[0024] Both the storage bin 210 and the baffle 250 have inclined surfaces at their bottoms, with the side of the inclined surface closer to the storage tube 212 being lower than the horizontal line of the other side. This design utilizes gravity to guide the titanium chopsticks to slide automatically towards the storage tube 212 without the need for additional power, reducing feeding resistance, preventing the chopsticks from getting stuck in the storage bin 210, improving feeding smoothness, and reducing the probability of failure of the feeding mechanism 200.

[0025] Specifically, limit plates 234 are installed on both sides of the top of the bracket 231, and the two feeding screws 232 are located between the two limit plates 234. The side of the bracket 231 near the storage shell 212 is extended outward. In this design, the limit plates 234 form a guiding and limiting structure, which can restrict the lateral displacement of the titanium chopsticks on the feeding screws 232, prevent the chopsticks from leaving the range of the feeding screws 232 during the conveying process, and ensure the stability of the feeding path. The outward extension of the bracket 231 near the storage shell 212 can expand the receiving range and ensure that the titanium chopsticks falling from the storage shell 212 can accurately land on the two feeding screws 232, avoiding missed connections or offsets, and improving the connection efficiency of loading and feeding.

[0026] Specifically, the material feeding component 240 includes a servo motor 241 mounted on the bracket 231 and located on the side of the drive component 233. The output shaft of the servo motor 241 is fixedly connected to two dial wheels 242. The cross-section of the dial wheel 242 is an equilateral triangle. The joint between the inclined surface and the material storage shell 212, and one side of the material storage shell 212 are provided with clearance slots 214 for the dial wheel 242 to pass through. The above design utilizes the triangular corners to intermittently push the titanium chopsticks into the feeding component 230, which can precisely control the feeding speed and avoid excessive feeding at one time, which would cause the feeding screw 232 to accumulate and block. It forms a feeding and feeding coordination with the feeding component 230 in rhythm. The avoidance groove 214 is designed to provide rotation space for the dial wheel 242, ensuring that the dial wheel 242 can smoothly pass through the joint between the storage box 210 and the storage shell 212. This ensures that the feeding action is effective and does not affect the structural sealing of the storage box 210 and the storage shell 212, preventing chopstick residue from falling.

[0027] Specifically, the laser color marking machine 300 includes a first laser color painting machine 310 and a second laser color painting machine 320 with identical structures. The first laser color painting machine 310 and the second laser color painting machine 320 are respectively mounted on the top of the processing table 100. The first laser color painting machine 310 is used to mark the unplated area of ​​the titanium chopsticks until the boundary between the plating and unplated areas. The second laser color painting machine 320 is used to mark the plating area of ​​the titanium chopsticks. In this design, the first laser color painting machine 310 marks the unplated area, and the second laser color painting machine 320 marks the plating area, respectively adapting to the surface characteristics of the titanium chopsticks before and after plating. This avoids wear on the markings in the unplated area during the plating process, while ensuring the adhesion and durability of the markings in the plating area. Furthermore, it allows for a natural transition between the markings in the two areas at the boundary, without obvious breaks, improving the integrity and aesthetics of the product's appearance.

[0028] Specifically, the electroplating equipment 400 is installed on the top of the processing table 100 and located between the first laser painting machine 310 and the second laser painting machine 320; the scratching equipment 500 is installed on the top of the processing table 100 and located close to the second laser painting machine 320; the collection box 600 is installed on one side of the processing table 100 and located diagonally below the scratching equipment 500; and the robotic arm 700 is installed on the top of the processing table 100 and located between the first laser painting machine 310, the second laser painting machine 320, the electroplating equipment 400, and the scratching equipment 500. In the above design, all equipment is rationally arranged around the robotic arm 700, shortening the material transfer path of the robotic arm 700, reducing material transfer time, and improving the connection speed of each process. The electroplating equipment 400 is located between the first laser color painting machine 310 and the second laser color painting machine 320, making the process of marking before electroplating, electroplating, and marking after electroplating seamless, avoiding unnecessary material transfer steps. The robotic arm 700 is located in the core position and can quickly grab the chopsticks on the feeding part 230 and transfer them to the laser color marking machine 300, the electroplating equipment 400, and the marking equipment 500, realizing the automated connection of each process, reducing manual intervention, and reducing human operation error.

[0029] Specifically, a guide trough 110 is installed at an angle through the processing table 100. One end of the guide trough 110 connects to the outlet of the scoring device 500, and the other end extends above the collection box 600. This design allows the inclined guide trough 110 to automatically transport the titanium chopsticks after scoring. Gravity allows the chopsticks to slide along the guide trough 110 into the collection box 600 without additional power. The precise connection between the guide trough 110 and the outlet of the scoring device 500 prevents the chopsticks from falling or colliding during transfer, ensuring the integrity of the workpiece's appearance. It also simplifies the collection process and reduces the workload of manual collection.
