Description

Technical Field

[0001] This utility model relates to the field of engraving machine technology, specifically a desktop jewelry engraving machine. Background Technology

[0002] Jewelry is a common type of ornament, and it is becoming increasingly popular as people's living standards improve. As a result, jewelry carving has become an essential means of jewelry processing. With the improvement of people's living standards, the need for jewelry is no longer limited to a small group of people, but has gradually become the need of the general public. People's needs and industrial development have made the industrialization of jewelry processing possible. Therefore, people have gradually developed mechanized carving, such as carving with rotary carving tools.

[0003] In existing technologies, traditional jewelry carving equipment typically relies on manual cleaning of metal shavings generated during processing, or simply on open receiving trays for collection.

[0004] However, manual cleaning must be done during processing intervals, which not only interrupts the processing flow and reduces overall processing efficiency, but also, if the manual cleaning is not done properly, may touch parts that have not completely stopped or scratch the surface of the processed jewelry. On the other hand, simple receiving trays are not enough to collect all the flying debris. A large amount of debris will accumulate on the worktable, in the gaps between the fixtures, and in the corners inside the equipment. As the processing time increases, the accumulated debris will affect the relative positional accuracy of the engraving tool and the workpiece, causing deviations in the engraved pattern. At the same time, the friction between the debris and the surface of the workpiece will increase the risk of scratches on the surface of the jewelry and reduce the product qualification rate.

[0005] In light of this, we are launching a desktop jewelry engraving machine. Utility Model Content

Detailed Implementation

[0033] 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.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped with", "sleeved with", "connected", etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0035] Please see Figure 1-8 This utility model provides a technical solution: a desktop jewelry engraving machine, comprising: a shell 1 that not only provides stable protection for the internal components, but also has a cabinet door 7 on its surface that can effectively isolate debris and noise during the processing. The transparent panel 6 (made of acrylic material) on the cabinet door 7 allows the operator to observe the jewelry processing status in real time. With the handle 18, the cabinet door can be easily opened and closed for taking and putting in workpieces or maintenance operations. The base 2 at the bottom of the shell increases the contact area with the desktop, improves the stability of the equipment placement, and avoids the impact of vibration on accuracy during processing.

[0036] The positioning frame 8 serves as the core support structure, providing a solid mounting foundation for key components such as the Y-axis servo lead screw linear module 19 and the concave support frame 12, ensuring the rigidity and stability of each module during operation. The Y-axis servo lead screw linear module 19, driven by a high-precision servo, drives the top worktable 10 to move smoothly back and forth. The clamp 20 on the top of the worktable 10 is specifically used for fixing jewelry workpieces. Its internal threaded rod 24 with bidirectional threads can drive two sets of clamping blocks 25 to move synchronously in opposite directions or in the opposite direction under the drive of the knob 23, which can quickly adapt to jewelry workpieces of different sizes. The rubber pads 26 on the surface of the clamping blocks 25 can enhance the clamping force and avoid damaging the surface of the jewelry, ensuring the integrity of the workpiece.

[0037] The concave support frame 12 spans the top of the positioning frame 8, providing a stable mounting platform for the X-axis servo lead screw linear module 13. The X-axis servo lead screw linear module 13 can drive the Z-axis servo lead screw linear module 14 to achieve precise left and right movement, while the Z-axis servo lead screw linear module 14 drives the engraving machine 15 to complete the up and down feed action. The three work together to form an X, Y, Z three-axis linkage system. Combined with the high-precision characteristics of servo drive, it ensures that the engraving machine 15 can complete the engraving of fine textures and patterns on the surface of jewelry according to the preset program, meeting the high precision requirements of jewelry processing.

[0038] Folded protective curtains connected to both ends of the Y-axis servo screw linear module 19 are added to both sides of the moving seat of the Y-axis servo screw linear module 19. In this way, the waste material during the engraving process will not affect the operation and accuracy of the Y-axis servo screw linear module 19.

[0039] Meanwhile, folding protective curtains connected to both ends of the Z-axis servo lead screw linear module 14 are added to both sides of the moving seat of the Z-axis servo lead screw linear module 14. In this way, the waste material during the engraving process will not affect the operation and accuracy of the Z-axis servo lead screw linear module 14 lead screw.

[0040] Folded protective curtains connected to both ends of the X-axis servo lead screw linear module 13 are added to both sides of the moving seat of the X-axis servo lead screw linear module 13. In this way, the waste material during the engraving process will not affect the operation and accuracy of the lead screw of the X-axis servo lead screw linear module 13.

[0041] To address the debris generated during processing, the equipment is equipped with a highly efficient blowing mechanism. The through hole 27 on the side of the outer shell 1 provides a stable air source for the air pump 16. The air pump 16 is mounted on both sides of the Z-axis servo lead screw linear module 14 via the positioning plate 17. When moving with the Z-axis, the air outlet 22 connected to its bottom pipe 21 can accurately align with the surfaces of the worktable 10 and the fixture 20. The blown air can promptly blow the debris away from the processing area, preventing debris accumulation from affecting processing accuracy or scratching the workpiece. The blown debris falls into the storage cavity 11 at the bottom through the gap between the worktable 10 and the positioning frame 8, and is finally collected in the collection box 5 inside the storage cavity 11. The collection box 5 can be easily removed for cleaning, realizing centralized collection and processing of debris, and keeping the inside of the equipment and the worktable clean.

[0042] In addition, the control panel 3 located on the side of the cabinet door 7 on the surface of the outer shell 1 integrates the operation and control functions of the equipment. Operators can set processing parameters and control the operation of each module through the buttons on it. The emergency stop button 9 on the control panel 3 serves as a safety device. In case of emergency, pressing it will instantly cut off the power of the Y-axis, X-axis, and Z-axis servo lead screw linear modules and the engraving machine 15, ensuring that the equipment stops working immediately and avoiding accidents. The display panel 4 above the control panel 3 is used to display the equipment operating parameters, processing progress, fault information, etc. in real time, so that operators can monitor the equipment status and adjust the processing strategy in a timely manner.

[0043] Specifically, when the device (i.e., the outer casing 1) is placed on the table, the base 2 at the bottom provides stable support for the whole machine, ensuring that the engraving accuracy will not be affected by vibration during processing. The operator starts the device through the control panel 3 on the surface of the outer casing 1. At this time, the display panel 4 will light up and display various initial parameters of the device, such as the current position of each axis, engraving speed, and operating mode, so that the operator can intuitively understand the status of the device. After the device is started, the Y-axis servo lead screw linear module 19, the X-axis servo lead screw linear module 13 and the Z-axis servo lead screw linear module 14 will automatically perform a reset operation and return to the preset origin position to prepare for subsequent precise engraving and ensure the accuracy of the initial position between the engraving machine 15 and the worktable 10.

[0044] The operator grasps the handle 18 on the surface of cabinet door 7 to open it, then places the jewelry to be processed onto the clamp 20 on top of workbench 10. Next, the operator turns knob 23, which causes the threaded rod 24 of the bidirectional threaded part inside clamp 20 to rotate. Because the threaded rod 24 adopts a bidirectional threaded design, the two sets of clamping blocks 25 on its surface will move relative to each other along the threaded rod 24 under the action of the thread, that is, they will move towards the center at the same time until the jewelry is firmly clamped. (The two sets of clamping blocks 25 are provided with guide blocks on their sides, and the guide blocks slide inside the clamp 20. The clamp 20 has openings for sliding...) The guide groove of the guide block allows the two sets of clamping blocks 25 to move linearly closer or further away within the clamp 20. During the clamping process, the rubber pad 26 on the surface of the clamping block 25 directly contacts the jewelry. The rubber material is soft and can effectively avoid hard contact between the clamping block 25 and the jewelry, preventing scratches or damage to the surface of the jewelry. This ensures the integrity of the jewelry and prevents it from shifting during processing. After the jewelry is fixed, the operator closes the cabinet door 7. The processing status of the jewelry inside the outer shell 1 can be clearly observed through the transparent plate 6 on the surface of the cabinet door 7, facilitating real-time monitoring of the processing progress and status.

[0045] Once the jewelry is secured and the engraving parameters are set, the equipment begins the engraving operation. The X-axis servo lead screw linear module 13, mounted on the surface of the concave support frame 12, moves left and right along the concave support frame 12 according to a preset program. This, in turn, moves the Z-axis servo lead screw linear module 14 mounted on its surface and the engraving machine 15 together, adjusting the position of the engraving machine 15 in the X-axis direction. This ensures that the engraving head of the engraving machine 15 can accurately align with the horizontal area of ​​the jewelry to be engraved. The Z-axis servo lead screw linear module 14 is responsible for driving the engraving machine 15 up and down, adjusting the engraving depth of the engraving machine 15 by precisely controlling the movement distance. To meet different carving requirements, such as bas-relief and deep carving, the Y-axis servo lead screw linear module 19 drives the worktable 10 to move back and forth, thereby moving the jewelry placed on the worktable 10 in the Y direction. In coordination with the X-axis and Z-axis movements, the carving machine 15 can perform all-round, high-precision carving operations on the surface of the jewelry according to the preset pattern and path. During the entire carving process, the X-axis servo lead screw linear module 13, Z-axis servo lead screw linear module 14 and Y-axis servo lead screw linear module 19 achieve extremely high motion precision through precise motor drive and lead screw transmission, ensuring the delicacy and accuracy of the carved pattern.

[0046] During the engraving process, a large amount of metal shavings are generated. If these shavings remain on the surfaces of the worktable 10 and the fixture 20, they will not only affect the subsequent engraving accuracy but may also cause wear to the equipment. To solve this problem, the equipment is equipped with a special blowing mechanism. Positioning plates 17 are installed on both sides of the Z-axis servo lead screw linear module 14, and the air pump 16 is fixed to the side of the positioning plate 17. When the equipment starts engraving, the air pump 16 starts simultaneously. Outside air enters the air pump 16 through the through hole 27 on the side of the outer casing 1. After being compressed by the air pump 16, it is circulated through the connection to the bottom of the air pump 16. The compressed air is delivered to the air outlet 22 through the pipe 21. The air outlet 22 is located above the worktable 10 and the fixture 20. It can blow out compressed air at a certain pressure, which directly acts on the surface of the worktable 10 and the fixture 20, blowing away the chips generated during carving. Under the action of gravity, the blown chips will fall into the storage cavity 11 located at the bottom of the positioning frame 8, and finally fall into the collection box 5 inside the storage cavity 11. This realizes the automatic cleaning and centralized collection of chips, which is convenient for subsequent unified processing. The operator can pull out the collected chips through the collection box 5 for cleaning, which facilitates operation.

[0047] In the event of an emergency during equipment operation, such as loose jewelry, deviation of the engraving path, or abnormal noise from the equipment, the operator can quickly press the emergency stop button 9 on the control panel 3 on the surface of the outer casing 1. Once the emergency stop button 9 is pressed, it will immediately cut off the power supply to the Y-axis servo lead screw linear module 19, the X-axis servo lead screw linear module 13, the Z-axis servo lead screw linear module 14, and the engraving machine 15, causing these components to stop working immediately. This prevents the equipment from continuing to operate and causing more serious consequences such as damage to the jewelry, equipment failure, or even personal injury, thus ensuring the safety of the equipment and the operator.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
