[0002] In today's electronics manufacturing industry, metal circuit boards are a key component of electronic products. Their processing quality and efficiency directly affect product performance and market competitiveness. Metal cutting machines occupy a core position in the metal circuit board processing flow, and the ejector pin device, as an important sub-component of the metal cutting machine, has a profound impact on the processing effect of metal circuit boards.

[0003] However, existing metal cutting ejector pin devices often lack automatic ejector pin interlock control, making the process of placing the ejector pins cumbersome, especially when changing to process different product models or part numbers. This requires a significant amount of time to place the ejector pins, wasting considerable working time and reducing product processing efficiency. Therefore, to address these issues, an improved automatic ejector pin device for metal cutting machines is proposed. Summary of the Invention

[0004] The purpose of this utility model is to provide an automatic ejector pin device for a metal cutting machine. By setting a linkage structure between a drive component and an air supply component on the base, the piston end of the drive component drives the ejector pin to move up and down along the movable groove of the fixed seat via a connecting block. This eliminates the need for manual placement of the ejector pin, solving the problems of existing ejector pin devices that cannot be automatically controlled and lack interlocking association. It significantly reduces the complexity of manual operation and reduces human error, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an automatic ejector pin device for a metal cutting machine, comprising a base and a drive assembly, wherein a support base is fixedly connected around the base, and a fixing base is fixedly connected to the top of the support base; The drive assembly is mounted on the base. The lower end of the drive assembly is connected to an air supply assembly. A connecting block is fixedly connected to the piston end of the drive assembly. A pin is mounted on the upper surface of the connecting block. A movable groove is opened on the surface of the fixed base at the position corresponding to the pin. The upper end of the pin passes through the movable groove and extends upward.

[0006] Preferably, the drive assembly consists of 64 cylinders of the same specification. The 64 cylinders are arranged in a matrix on the upper surface of the base, specifically, 8 rows of cylinders are spaced apart along the length of the base and 8 columns of cylinders are spaced apart along the width of the base, and the center distance between any two adjacent rows of cylinders is equal and the center distance between any two adjacent columns of cylinders is equal.

[0007] Preferably, the air supply assembly consists of 8 air supply pipes with the same structure. Each air supply pipe is set to correspond to 8 cylinders in a row in the drive assembly, and the air outlet of each air supply pipe is connected to the air inlet of the corresponding 8 cylinders in the row, so as to realize that a single air supply pipe can provide air pressure to the corresponding 8 cylinders in the row simultaneously.

[0008] Preferably, a guide groove is provided at the center of the fixed base, the guide grooves are arranged in a crisscross pattern, and the intersection of the guide grooves corresponds to the position of the movable groove.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides an automatic ejector pin device for a metal cutting machine. Through the linkage of a drive component and an air supply component on the base, the piston end of the drive component drives the ejector pin to move along the movable groove of the fixed seat via a connecting block, achieving automated ejector pin control. This eliminates manual placement, solves the problem of existing devices lacking automatic control and interlocking, reduces operational complexity and human error, and avoids frequent manual adjustments to the ejector pin layout during product changeovers by a standardized drive component installation structure and synchronous control with the air supply component.

[0014] 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.

[0015] This utility model provides, for example Figures 1-4 The automatic ejector pin device for a metal cutting machine shown includes a base 1 and a drive assembly 2. Support seats 3 are fixedly connected around the base 1, and a fixing seat 4 is fixedly connected to the top of the support seats 3. The drive assembly 2 is mounted on the base 1. The lower end of the drive assembly 2 is connected to the air supply assembly 5. The piston end of the drive assembly 2 is fixedly connected to the connecting block 6. The upper surface of the connecting block 6 is equipped with a ejector pin 7. The surface of the fixed base 4 is provided with a movable groove 8 at the position corresponding to the ejector pin 7. The upper end of the ejector pin 7 passes through the movable groove 8 and extends upward. This device is based on the base 1, and the support seats 3 around the base 1 firmly support the fixed seat 4, forming a rigid frame structure of "base 1-support seats 3-fixed seat 4". The air supply component 5 provides power to the drive component 2 installed on the base 1. The piston end of the drive component 2 drives the ejector pin 7 to move through the fixed connecting block 6. The ejector pin 7 can extend and retract along the movable groove 8 opened on the surface of the fixed seat 4 (the upper end extends through the movable groove 8 to the top of the fixed seat 4), realizing the lifting and lowering action control of the ejector pin 7, thereby completing the support or detachment operation of workpieces such as metal circuit boards. Breaking the limitation of the existing ejector pin 7 device being "manually placed": Through the linkage structure of "air supply component 5 - drive component 2 - connecting block 6 - ejector pin 7", the ejector pin 7 is automatically raised and lowered, eliminating the need for manual adjustment of the ejector pin 7 position, thus solving the core problems of the existing device lacking automatic control and the ejector pin 7 lacking interlocking association; The movement of the ejector pin 7 along the movable groove 8 can avoid displacement, reduce the positional error of manual placement, simplify the operation process, reduce the complexity of manual operation, lay the foundation for the stability of subsequent processing, and improve the convenience and accuracy of operation.

[0016] The drive assembly 2 consists of 64 cylinders 21 of the same specifications. The 64 cylinders 21 are arranged in a matrix on the upper surface of the base 1. Specifically, 8 rows of cylinders 21 are spaced apart along the length of the base 1 and 8 columns of cylinders 21 are spaced apart along the width of the base 1. The center distance between any two adjacent rows of cylinders 21 is equal and the center distance between any two adjacent columns of cylinders 21 is equal. The 64 cylinders are evenly distributed in a matrix, which makes the support force of the ejector pins on the workpiece more balanced, avoiding workpiece deformation caused by uneven local force, and is especially suitable for the processing needs of thin and fragile workpieces such as metal circuit boards. Meanwhile, the standardized matrix layout can cover metal circuit boards of different sizes and shapes, eliminating the need to redesign the pin distribution for specific workpieces and providing a structural basis for subsequent rapid model changeovers.

[0017] The air supply assembly 5 consists of 8 air supply pipes 51 with the same structure. Each air supply pipe 51 is set to correspond to 8 cylinders 21 in a row in the drive assembly 2, and the air outlet of each air supply pipe 51 is connected to the air inlet of the corresponding 8 cylinders 21 in the row, so as to realize that a single air supply pipe 51 provides air pressure to the corresponding 8 cylinders 21 in the row simultaneously. The air supply assembly 5 includes eight identical air supply pipes 51, each of which precisely corresponds to one of the eight cylinders 21 in a row in the drive assembly 2. The outlet of the air supply pipe 51 is connected to the air inlet of each of the eight cylinders 21 in the corresponding row. A control valve is installed at the connection of the air inlet of each cylinder 21 to control the air pressure supplied to the cylinder 21. When air is supplied to a cylinder 21, the piston end of the cylinder 21 drives the ejector pin 7 to rise and fall. When changing to different models, it is not necessary to manually adjust each of the 64 ejector pins 7 one by one. The layout of the ejector pins 7 can be adjusted simply by controlling the corresponding row of air supply pipes 51, which greatly reduces the changeover time and improves processing efficiency.

[0018] A guide groove 9 is provided at the center of the fixed base 4. The guide grooves 9 are arranged in a crisscross pattern, and the intersection of the guide grooves 9 corresponds to the position of the movable groove 8. A loop groove 10 is provided around the guide groove 9 on the fixed base 4. A conveying groove 11 is provided at equal intervals on one side wall of the fixed base 4, which intersects with the loop groove 10. A connector 12 is provided at the outer port of the conveying groove 11. Lubricating fluid (such as special lubricating oil or grease) is pre-injected into the loop groove 10 of the fixed seat 4, or connected to an external lubricating fluid supply device (such as a micro oil pump) through the connector 12, so that the lubricating fluid continuously or as needed enters the loop groove 10; since the guide grooves 9 are arranged in a crisscross pattern and their confluence positions correspond to the movable groove 8, the lubricating fluid in the loop groove 10 can flow naturally along the guide grooves 9, and finally seep into the interior of the movable groove 8 through the corresponding positions of the guide grooves 9 and the movable groove 8; when the ejector pin 7 moves up and down in the movable groove 8, it will come into full contact with the seeped lubricating fluid, so that a uniform lubricating film is formed between the outer wall of the ejector pin 7 and the inner wall of the movable groove 8; The formation of the lubricating film can effectively reduce the direct friction between the ejector pin 7 and the movable groove 8, avoid serious wear caused by dry friction, extend the service life of the ejector pin 7 and the fixed seat 4, reduce the frequency of equipment maintenance or replacement due to component wear, and reduce the cost of use. At the same time, reducing friction can prevent the ejector pin 7 from getting stuck or jammed in the movable groove 8, ensuring that the ejector pin 7 can accurately and smoothly achieve lifting and lowering actions, further improving the stability of supporting or detaching workpieces such as metal circuit boards, and indirectly ensuring processing accuracy.

[0019] Each row of cylinders 21 is provided with a partition plate 13 on both sides, and the upper end of the partition plate 13 is fixedly connected to the bottom of the fixed seat 4. The partition 13 provides lateral restraint for each row of cylinders 21, which can prevent the cylinders 21 from shifting laterally when the piston is driven by air pressure. At the same time, it assists in the support between the fixed seat 4 and the base 1, and enhances the rigidity of the overall structure. The lateral limiting function of the partition 13 can reduce the shaking of the cylinder 21 during the lifting and lowering process, ensuring that the piston end drives the ejector pin 7 to move in the preset direction, avoiding positional deviation of the ejector pin 7 due to the offset of the cylinder 21, and ensuring machining accuracy. The partition 13 connects the fixed seat 4 and the base 1, further reinforcing the frame structure of "base 1-fixed seat 4", reducing component loosening caused by vibration during long-term use, and extending the overall service life of the device.

[0020] 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.
