Description

Technical Field

[0001] This utility model belongs to the field of loading and unloading equipment, and particularly relates to an automatic feeding component for a precision engraving machine. Background Technology

[0002] A CNC engraving machine is a type of CNC machine tool used for grinding, cutting, and other processing of products. Currently, CNC engraving machines do not come with an automatic feeding mechanism; they are primarily fed manually or by an external feeding machine. The external feeding machine is usually a robotic arm. Robotic arm feeding can replace manual feeding, but it requires a specially designed material feeder that works in conjunction with the robotic arm to complete the feeding process. Its control system is complex, requires multiple alignments, and necessitates professional debugging personnel. Utility Model Content

[0003] The purpose of this invention is to provide an automatic feeding component for a precision engraving machine to solve the problem of inconvenient feeding in existing precision engraving machines.

[0004] To address the above problems, this utility model discloses an automatic feeding component for a precision engraving machine, comprising:

[0005] The machine has a fixed frame on one side of its upper part, and a fixture is placed on the top of the fixed frame.

[0006] The placement frame is located on one side of the machine.

[0007] The transport component is located on one side of the placement frame;

[0008] The placement frame includes a connecting base plate, an outer support column, a limiting plate, an inner support column, a top plate, and a platform. The connecting base plate is disposed on the machine platform, the outer support column is installed on the connecting base plate, the outer support column passes through the limiting plate and connects upward to the top plate, the inner support column is installed on the limiting plate, the platform is disposed above the limiting plate, and the platform is provided with several grooves, the grooves slidingly engaging with the inner support column. The limiting plate is provided with a through slot. The handling assembly includes a lifting mechanism and a handling mechanism. The lifting mechanism includes a lifting plate, the size of which is smaller than the size of the through slot.

[0009] As a further improvement to the above technical solution:

[0010] The conveying mechanism includes a column and a truss, the truss and the column are connected, the column is installed on the machine platform, a lateral moving module is provided on the truss, a lifting cylinder is provided at the output end of the lateral moving module, and a suction cup assembly is provided at the lower end of the lifting cylinder.

[0011] The machine base is provided with a base, and the connecting base plate is installed on the base through a first pressure plate.

[0012] There are at least two sets of placement frames.

[0013] The placement fixture includes a sinking trough, with an extension groove on one side of the sinking trough and anti-collision rounded corners at the four corners of the sinking trough.

[0014] The upper part of the sinking trough is provided with protrusions.

[0015] The lifting mechanism includes a carriage, the lifting plate is slidably engaged with the carriage, and a lifting drive assembly is provided inside the carriage, which is connected to the lifting plate.

[0016] The lifting drive assembly includes a servo motor, a synchronous pulley, and a synchronous belt. The servo motor is mounted on one side of the carriage, one synchronous pulley is mounted on the output end of the servo motor, and the other synchronous pulley is mounted on the upper part of the carriage. The synchronous belt is sleeved on the two synchronous pulleys and is fixedly connected to the lifting plate.

[0017] The lateral movement module is a lead screw drive structure or a synchronous belt drive structure.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Increase automation and reduce labor costs: By working together with the handling components and the placement frame, the workpiece is transferred from storage to the processing station in a fully automated manner. There is no need for manual loading, which greatly reduces the input of manpower, reduces the labor intensity of manual operation, and avoids possible errors when loading manually.

[0020] Improve material feeding efficiency and ensure continuous production: The design of at least two sets of placement frames allows for simultaneous replenishment of workpieces to the other set while one set is being fed, achieving uninterrupted material feeding. This effectively reduces downtime caused by waiting for material loading and significantly improves the overall processing efficiency of the engraving machine.

[0021] Ensuring positioning accuracy and improving processing quality: The placement of the fixture for precise workpiece positioning facilitates loading by the robotic arm or other feeding mechanisms, reducing the robotic arm's alignment time and improving loading efficiency. The fixture's recessed groove, protrusions, and rounded corners ensure accurate workpiece positioning and protection; the lateral movement module of the conveying mechanism, in conjunction with the lifting cylinder, guarantees the stability of the workpiece transfer process. This multi-layered structural design collectively ensures the accuracy of the workpiece feeding position, providing a reliable benchmark for precision engraving and ultimately improving the processing quality of the final product.

[0022] Enhanced equipment adaptability and expanded application range: The sliding fit between the frame and the inner support column, and the sliding design between the limiting plate and the outer support column, allow the placement frame to adapt to the storage needs of workpieces of different heights and specifications; the structure of the suction cup assembly can also be flexibly adjusted according to the shape of the workpiece, improving the adaptability of the components to various workpiece types and expanding the application range of the engraving machine.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0032] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" 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. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] 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.

[0035] like Figure 1 and Figure 2 As shown, the automatic feeding component of the engraving machine in this embodiment includes:

[0036] Machine base 1 serves as the mounting foundation for the entire feeding assembly. It houses both electrical and pneumatic control systems, and includes a heat dissipation system for cooling the electrical control system. A set of casters is installed at the bottom of machine base 1 for easy movement. A fixed frame 11 is mounted on one side of the upper part of machine base 1, with a placement fixture 12 mounted on top of the frame 11. The placement fixture 12 is mounted on the fixed frame 11 via a second pressure plate. The placement fixture 12 receives and positions the workpieces conveyed by the feeding assembly, providing a stable reference and positioning for subsequent precision engraving. The robotic arm can directly pick up the product from the placement fixture 12 without further positioning, using the center of the placement fixture 12 as the reference point, thus improving feeding efficiency.

[0037] Placement frame 2 is located on one side of machine base 1; multiple layers of products are placed inside placement frame 2. To achieve uninterrupted material supply, placement frame 2 is configured in two sets. When one set is in the feeding state, the other set can simultaneously replenish workpieces, significantly reducing downtime. Figures 3 to 5As shown, the placement frame 2 includes a connecting base plate 21, an outer support column 22, a limiting plate 23, an inner support column 24, a top plate 25, and a platform 26. The connecting base plate 21 is mounted on the machine base 1, and a base 20 is mounted on the machine base 1. The connecting base plate 21 is mounted on the base 20 via a first pressure plate, facilitating later maintenance and adjustment. The outer support column 22 is mounted on the connecting base plate 21 and passes through the limiting plate 23 to connect upwards to the top plate 25. The inner support column 24 is mounted on the limiting plate 23. The platform 26 is positioned above the limiting plate 23 and has several grooves that slide in conjunction with the inner support column 24. The limiting plate 23 has a through groove 27.

[0038] A transport assembly 3 is disposed on one side of the placement frame 2; the transport assembly 3 is used to transport the products in the placement frame 2 to the placement fixture 12. The transport assembly 3 includes a lifting mechanism 31 and a transport mechanism 32. The lifting mechanism 31 includes a lifting plate 311, the size of which is smaller than the size of the through slot 27, which provides operating space for the lifting mechanism. The lifting mechanism 31 drives the lifting plate 311 upward, thereby moving the platform 26 and the products on the platform 26 upward, so that the transport mechanism 32 can transport them.

[0039] The conveying mechanism 32 is used to grab the lifted workpiece and transfer it to the placement fixture 12. The conveying mechanism 32 includes a column 321 and a truss 322. The truss 322 is fixedly connected to the top of the column 321. The column 321 is vertically installed on the machine base 1. A transverse moving module 323 is provided on the truss 322. A lifting cylinder 324 is provided at the output end of the transverse moving module 323. A suction cup assembly 325 is provided at the lower end of the lifting cylinder 324. The transverse moving module 323 adopts a synchronous belt drive structure here. The transverse moving module 323 drives the suction cup assembly 325 to move laterally, and the lifting cylinder 324 drives the suction cup assembly 325 to rise and fall. With the vacuum adsorption function of the suction cup assembly, the stable grabbing and transfer of the workpiece is achieved.

[0040] like Figure 5 and 6 As shown, the lifting mechanism 31 includes a carriage 312, a lifting plate 311 that is slidably engaged with the carriage 312, and a lifting drive assembly 313 that is disposed inside the carriage 312 and connected to the lifting plate 311.

[0041] The lifting drive assembly 313 includes a servo motor 3131, a synchronous pulley 3132, and a synchronous belt 3133. The servo motor 3131 is mounted on one side of the carriage 312. One synchronous pulley 3132 is mounted on the output end of the servo motor 3131, and the other synchronous pulley 3132 is mounted on the upper part of the carriage 312. The synchronous belt 3133 is sleeved on the two synchronous pulleys 3132 and fixedly connected to the lifting plate 311. The servo motor 3131 drives the synchronous belt 3133 to achieve high-precision lifting of the lifting plate 311. It should be noted that a synchronous belt is used as the lifting drive structure here. A lead screw drive structure can also be used for the lifting drive assembly; the choice depends on the actual requirements.

[0042] like Figure 7 As shown, the placement fixture 12 includes a recessed groove 121, with an insertion groove 122 on one side and anti-collision rounded corners 123 at the four corners. The recessed groove 121 has chamfered edges to facilitate product entry. The internal dimensions of the recessed groove 121 are slightly larger than the product dimensions (not exceeding 1mm). The anti-collision rounded corners 123 prevent damage to the workpiece due to collision during placement, avoiding edge breakage. The insertion groove 122 allows the part to be inserted into the recessed groove 121 for product removal. A protrusion 124 is provided on the upper part of the recessed groove 121 to support the product. This design prevents negative pressure adhesion between the product and the recessed groove 121, facilitating product removal. The size of the protrusion 124 is smaller than the size of the recessed groove 121 (this size refers to the area of ​​the upper contact surface). The height of the protrusion 124 should be such that the upper surface of the product protrudes beyond the recessed groove 121, ensuring an airflow gap between the product and the bottom of the recessed groove for easy product removal.

[0043] The workflow of this automatic feeding assembly is as follows: Products to be processed are placed in batches on the frame 26 of the placement frame 2. The lifting plate 311 of the lifting mechanism 31 passes through the through slot 27 of the limiting plate 23, driving the frame 26 to rise along the inner support column 24, sending the uppermost workpiece to the gripping height. The lateral movement module 323 of the conveying mechanism 32 drives the suction cup assembly 325 to move above the workpiece. The lifting cylinder 324 extends, causing the suction cup assembly to contact and adhere to the workpiece. Subsequently, the lifting cylinder retracts, and the lateral movement module moves the workpiece above the placement fixture 12. The lifting cylinder extends again, placing the workpiece into the sink trough 121. The suction cup assembly releases the workpiece, completing one feeding cycle. Compared to existing technologies, this invention uses a placement fixture 12. Products are placed on the placement fixture 12 by the conveying assembly 3, and the robotic arm can directly remove the products from the placement fixture 12, reducing the robotic arm's operating time. The placement fixture 12 positions the products, reducing the robotic arm's alignment time and helping to improve feeding efficiency.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description.
