Description

Technical Field

[0001] The utility model relates to the technical field of laser processing, in particular to a glue dispensing and drying structure on a machine tool. Background Art

[0002] Diamonds are typically made from natural diamonds and / or synthetic diamonds. Companies are now turning to laser processing machines for cutting diamonds, enabling more efficient and precise processing. To improve processing efficiency and ensure continuous production, a dual-station approach is necessary for cutting diamond blanks. Specifically, after securing the pavilion of the diamond blank on a bonding platform at the first station, the crown and girdle of the finished diamond are first machined. Glue is then applied to the bonding platform at the second station, and the crown of the finished diamond is bonded to the bonding platform at the second station. Laser cutting is then performed at the glued-on point on the pavilion of the diamond blank, freeing it from the bonding platform at the first station. The bonding platform at the first station can then secure and adjust the next diamond blank to be processed. Simultaneously, the second station and laser work together to process the pavilion of the diamond blank into the pavilion of the finished diamond. If manual glue is used to dispense glue on the bonding platform of the second workstation, the following problems will arise: 1. The process will be interrupted for a long time because the operator has to wait for the operator to operate. 2. The second workstation is close to the middle of the machine tool, making it inconvenient for the operator to reach inside the machine tool to dispense glue. 3. After manual glue dispensing, the operator can only wait for the glue to cure naturally, which is time-consuming and affects processing efficiency.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Utility Model Content

DETAILED DESCRIPTION

[0016] The present invention provides a glue dispensing and drying structure for a machine tool. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to explain the present invention and are not intended to limit the scope of protection of the present invention.

[0017] See also Figure 1 The utility model provides a glue dispensing and drying structure on a machine tool, including a gantry 11 arranged on a bed, an X-axis saddle 12 slidably arranged on the gantry 11, an X-axis driving mechanism 13 for driving the X-axis saddle 12 to move left and right, a Z-axis saddle 14 arranged on the X-axis saddle 12, and a Z-axis driving mechanism for driving the Z-axis saddle 14 to move up and down, a glue dispensing component 2 is provided on the Z-axis saddle 14, and the glue dispensing component 2 is used to perform glue dispensing and fixing on the workpiece, and a drying lamp 5 is provided at the bottom of the X-axis saddle 12.

[0018] In actual application, the machine tool is provided with a first station 41 and a second station 42. The bonding platform 43 on the second station 42 can move along the Y-axis direction and rotate in the A-axis and C-axis directions to change the position of the bonding platform 43. The dispensing component 2 can move in the X-axis and Z-axis directions under the drive of the X-axis drive mechanism 13 and the Z-axis drive mechanism. By cleverly utilizing the advantages of the machine tool, the dispensing component 2 also has multi-axis motion capabilities, and can achieve precise automatic dispensing of glue on the bonding platform 43. Not only can the dispensing component 2 pre-dispense glue on the bonding platform 43 in advance, but the workpiece can also be flexibly glued and reinforced after being glued to the bonding platform 43, thereby eliminating the interruption of work and the inconvenience of operation caused by manual dispensing, and improving production continuity and work efficiency. After the dispensing is completed, the bonding platform 43 moves to the bottom of the drying lamp 5, and the drying lamp 5 irradiates the bonding platform 43 after dispensing, which significantly accelerates the curing time of the glue. Fast-curing glue reduces the problem of unstable bonding caused by incomplete curing of the glue. It can maintain the stable positioning of the workpiece even in high-speed continuous processing, prevent the blank from falling off during processing, improve the reliability and continuity of processing, and help improve the dimensional accuracy and surface quality of the finished product.

[0019] It is understood that the machine tool is equipped with a visual camera that can take pictures of the workpiece, thereby accurately obtaining the position of the workpiece and ensuring the accuracy of the glue dispensing position. The Z-axis slide saddle 14 is equipped with a laser cutting head 15 located next to the glue dispensing component 2. The laser cutting head 15 emits a laser to process the workpiece and can also emit a laser to cut the workpiece bonding position, thereby disconnecting the workpiece from the bonding platform 43.

[0020] Specifically, the dispensing assembly 2 includes a bracket 21 fixed to the side of the Z-axis saddle 14 and a dispensing gun 22 disposed downward on the bracket 21. The dispensing gun 22 is mounted laterally on the Z-axis saddle 14, fully utilizing the vertical space of the machine tool and avoiding interference with other machine tool components, making the entire structure more compact and optimizing the internal layout of the machine tool; the dispensing gun 22 dispenses glue downward, ensuring that the glue can be accurately applied to the workpiece or the predetermined position on the bonding platform 43, reducing deviation or dripping during the dispensing process and improving the accuracy and consistency of the dispensing operation. The dispensing gun 22 can specifically be a pneumatic dispensing gun, an electric dispensing gun, or a jet dispensing gun, and the glue used for dispensing can be epoxy resin glue.

[0021] In this embodiment, the drying lamp 5 is a UV-LED curing lamp. UV-LED curing lamps are small and compact, making them easy to integrate into various machine tool structures without taking up too much space. Furthermore, the concentrated ultraviolet energy emitted by UV-LED curing lamps significantly shortens curing time and significantly improves production efficiency compared to traditional hot air or infrared drying methods.

[0022] The drying lamp 5 is irradiated downward, and a wing plate is provided on the lamp housing of the drying lamp 5, and an elongated hole is provided on the wing plate. The bottom surface of the X-axis saddle 12 is provided with a threaded hole corresponding to the elongated hole, and a fixing screw passes through the elongated hole and cooperates with the threaded hole. The elongated hole on the wing plate is used in conjunction with the threaded hole on the bottom surface of the X-axis saddle 12 to ensure that the drying lamp 5 is firmly installed on the machine tool. This structural design effectively prevents the drying lamp 5 from being displaced when the machine tool moves at high speed or vibrates, improves the stability of the processing process, avoids light deviation caused by equipment vibration, and ensures the consistency and reliability of the drying effect. The design of the elongated hole allows the drying lamp 5 to fine-tune its position along the X-axis direction within a certain range, which is convenient for adjusting the optimal irradiation position according to actual processing requirements or workpiece size, ensuring that the glue cures more evenly and thoroughly.

[0023] In order to prevent the glue outlet of the glue dispensing gun 22 from being clogged due to the glue drying up, which causes the glue outlet of the glue dispensing gun 22 to need to be manually cleaned every time the machine is started or when it is not in use for a long time, a clearing structure 3 for clearing the clogged glue outlet of the glue dispensing gun 22 is provided on the machine tool.

[0024] For details, see Figure 1 and Figure 2As shown, the blockage removal structure 3 includes a base 31 with an upper opening and an inner cavity, a heat melter 32 and an air blower 33 mounted on the base 31. The heat melter 32 is used to heat the glue outlet of the glue gun 22, and the air blower 33 uses compressed air to blow away blockages stuck to the glue outlet of the glue gun 22. This blockage removal structure 3 automatically heats and blows air into the glue outlet of the glue gun 22 before each startup or during processing intervals, effectively removing dried glue without manual intervention, significantly reducing the burden on operators and saving the time and cost of manual cleaning.
