Description

Technical Field

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

[0002] Laser marking machines for chopsticks are widely used in the catering industry and personal customization sector as essential equipment for personalized tableware customization and marking. However, existing laser marking equipment typically requires manual transfer of the chopsticks to a chemical solution container for post-processing after laser marking, a cumbersome and inefficient process. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a desktop chopsticks laser marking machine that achieves automatic avoidance and positioning of the cartridge through a linkage mechanism, which significantly improves production efficiency and ease of operation, while reducing the intensity of manual operation.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A desktop chopstick laser marking machine includes: a frame for supporting the entire marking machine; a laser marking device mounted on the frame for laser marking chopsticks; a clamping device mounted on the frame for clamping the chopsticks and controlling their rotation; a sliding frame mounted on one side of the laser marking device; a cartridge slidably connected to the sliding frame, containing a liquid for post-processing the chopsticks; a connecting rod hinged at one end to the cartridge and at the other end to the sliding frame, with a fixed length; a sliding frame controlling the vertical movement of the clamping device; a cartridge cover mounted on the cartridge, having multiple surrounding holes; and a stepper motor driving the cartridge cover to rotate. When the clamping device lowers the chopsticks, the connecting rod moves the cartridge away from the chopsticks. When the chopsticks are laser-marked and then moved upwards, the cartridge reaches below the chopsticks, and the chopsticks enter the holes for liquid immersion treatment.

[0006] This utility model is further configured as follows:

[0007] The connecting rod is hinged to the cartridge case and hinged to the sliding seat via a hinge pin;

[0008] The placement holes are evenly distributed on the top cover of the medicine cartridge. The diameter of each placement hole is larger than the diameter of the chopsticks, and the depth is sufficient to allow the marking position of the chopsticks to be completely immersed in the medicine.

[0009] The sliding frame includes a guide groove, and the cartridge slides within the guide groove via a sliding block to ensure the accuracy of the cartridge's movement trajectory;

[0010] The clamping device includes clamping claws and a rotary drive mechanism. The clamping claws are used to clamp chopsticks, and the rotary drive mechanism is used to drive the chopsticks to rotate to achieve multi-angle marking.

[0011] The sliding seat includes a lifting guide rod, and the clamping device achieves precise vertical movement through the lifting guide rod;

[0012] The length of the connecting rod is designed so that when the clamping device is in its lowest position, the horizontal distance between the medicine cartridge and the chopsticks is the greatest, and when the clamping device is in its highest position, the medicine cartridge is located directly below the chopsticks.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The level of automation has been significantly improved: the linkage mechanism enables the automatic avoidance and positioning of the cartridge without human intervention, which improves production efficiency compared to the traditional manual post-processing method. Operators only need to load and unload the chopsticks.

[0015] The processing quality is stable and reliable: the fixed connecting rod length ensures the repeatability of the positioning of the medicine cartridge, the soaking position of each chopstick is consistent, and the precise rotation controlled by the stepper motor ensures the consistency of the processing time. The consistency of processing quality is improved compared with manual operation.

[0016] Simple structure and low cost: The linkage transmission mechanism has a simple structure and lower manufacturing cost than complex electric control systems. Mechanical linkage avoids additional sensors and control devices, and the equipment manufacturing cost is lower than that of electrical automation solutions.

[0017] Convenient operation and maintenance: The desktop design adapts to various working environments, the equipment is compact and easy to move, the mechanical transmission system has a low failure rate and is easy to maintain, the equipment has a long service life, and the operation and learning costs are low.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] like Figure 1 As shown, this utility model provides a desktop chopsticks laser marking machine, which mainly includes a frame 1, a laser marking device 2, a clamping device 3, a sliding frame 4, a cartridge 5, a linkage mechanism, and a control system.

[0024] The frame 1 adopts a desktop structure. The laser marking device 2 is installed on the frame 1 and is used to laser mark chopsticks. It adopts a standard laser marking system and can form clear and durable marks on the surface of the chopsticks.

[0025] like Figure 2 As shown, the linkage mechanism is the core part of this utility model. One end of the connecting rod 6 is hinged to the cartridge 5, and the other end is hinged to a sliding seat 7, with a fixed length of the connecting rod. The sliding seat 7 controls the up and down movement of the clamping device 3, including a lifting guide rod 18, through which the clamping device 3 achieves precise vertical movement.

[0026] Working principle: When the clamping device 3 clamps the chopsticks and moves them downwards for laser marking, the sliding seat 7 moves downwards simultaneously. Due to the fixed length of the connecting rod 6, the geometric constraint forces the cartridge 5 to automatically move away from the chopsticks, avoiding interference with the marking process. After the laser marking of the chopsticks is completed, the clamping device 3 moves upwards, and the sliding seat 7 moves upwards simultaneously. The connecting rod 6 drives the cartridge 5 to automatically move to directly below the chopsticks, achieving automatic positioning.

[0027] like Figure 3 As shown, the cartridge 5 is slidably connected to the sliding frame 4, and the cartridge contains a liquid medicine for post-processing the chopsticks. The sliding frame 4 includes a guide groove 13, and the cartridge 5 slides within the guide groove 13 via a sliding block 14 to ensure the accuracy of the cartridge's movement trajectory.

[0028] A medicine cartridge cover 8 is mounted on the medicine cartridge 5, and the cover has multiple placement holes 9 arranged around the center. The placement holes 9 are evenly distributed on the medicine cartridge cover, and the diameter of each placement hole is larger than the diameter of a chopstick, and the depth is sufficient to allow the marking position of the chopstick to be completely immersed in the medicine liquid. A stepper motor 10 can be connected to the medicine cartridge cover 8 through a gear transmission mechanism to achieve precise step-by-step rotation control of the cover.

[0029] Workflow: After the chopsticks are marked and moved into position, the clamping device 3 releases the chopsticks, and the chopsticks enter the storage hole 9 under gravity for immersion in the solution. After treatment, the staff removes the chopsticks and places new chopsticks for clamping. The stepper motor 10 operates, driving the upper cover to rotate one step, aligning the next empty storage hole with the clamping device, and the above process is repeated.

[0030] like Figure 1 , Figure 2As shown, the clamping device 3 is mounted on the frame 1 and includes a clamping jaw 15 and a rotary drive mechanism 16. The clamping jaw 15 is used to clamp the chopsticks and adopts an adjustable clamping structure to accommodate chopsticks of different diameters. The rotary drive mechanism 16 is used to drive the chopsticks to rotate to achieve multi-angle marking, ensuring all-around marking on the surface of the chopsticks.

[0031] The clamping device achieves precise vertical movement via the lifting guide rod 18 of the sliding base 7. The movement range and speed can be adjusted according to process requirements. The clamping force is adjustable, ensuring stable clamping of the chopsticks while preventing damage.

[0032] The length of the connecting rod 6 is designed to maximize the horizontal distance between the cartridge 5 and the chopsticks when the clamping device 3 is in its lowest position, ensuring uninterrupted laser marking. When the clamping device 3 is in its highest position, the cartridge 5 is positioned directly below the chopsticks, achieving precise alignment.

[0033] To meet the processing needs of different types of chopsticks, the equipment parameters can be set as follows:

[0034] Bamboo chopsticks treatment: The soaking time in the solution is set to 30 seconds, the depth of the placement hole is 15mm, and the stepper motor rotation interval is 45 seconds. This method is suitable for the anti-corrosion and anti-mildew treatment of bamboo chopsticks.

[0035] Wooden chopsticks treatment: The soaking time in the solution is set to 45 seconds, the depth of the placement hole is 20mm, and the stepper motor rotation interval is 60 seconds. This method is suitable for surface strengthening treatment of wooden chopsticks.

[0036] Personalized customization: The marking content and processing technology can be adjusted according to customer requirements, and the type of chemical solution can be changed to a different functional processing solution to achieve personalized post-processing effects.

[0037] The process parameters are set to ensure the processing quality of different chopsticks, resulting in uniform processing effects, improved production efficiency compared to traditional manual processing, and good stability of continuous operation of the equipment.

[0038] Based on the technical effects stated in the instruction manual, the focus is on verifying the performance improvements of the desktop chopsticks laser marking machine in terms of automation level, processing quality, cost-effectiveness, batch processing capacity, and ease of operation.

[0039] Verification Method: A comparative experiment was conducted using standard bamboo chopsticks laser marking. The test conditions were: chopsticks with dimensions of Φ7×240mm, and laser marking content of a uniform identifier. The comparison samples consisted of three sets each of traditional manual post-processing equipment and the new linkage-linked automated equipment.

[0040] Main test items:

[0041] Production efficiency test: Statistics on the complete production cycle time and the number of chopsticks processed per unit time;

[0042] Quality testing: Measurement of consistency of drug immersion location and accuracy of treatment time;
