[0002] The punch needle assembly machine is a highly automated device. Its main function is to accurately assemble the needle seat, needle tube, sheath, protective cover and other components into a finished safety injection needle. This equipment is designed to improve production efficiency and product quality while reducing the need for manual operation. The punch needle pressing mechanism is the core part of the punch needle assembly machine. Its main task is to press the ejector pin into place at one time.

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0033] like Figure 1-4 As shown, the present application provides a punch pin pressing mechanism of a punch pin assembly machine, including a punch pin assembly machine body 1; a support column 101, fixedly installed on the top of the punch pin assembly machine body 1; a fixed plate 102, fixedly installed on the surface of the support column 101; a connecting column 103, fixedly installed on the bottom end of the fixing plate 102; a connecting plate 104, fixedly installed on the surface of the connecting column 103; a pressing component 2, fixedly installed on the top of the connecting plate 104, for pressing down the needle, the pressing component 2 includes a support frame 201, and a plurality of pressing cylinders 202 are installed on the top of the support frame 201, and a telescopic column 203 is slidably installed in the inner cavity of the pressing cylinder 202.

[0034] In this embodiment: a connecting plate 104 is provided, and the connecting plate 104 is mainly used for installing the pressing assembly 2 .

[0035] Specifically, Figure 2 , 3As shown in Figure 4, the downward pressure component 2 includes a high-pressure module 204 and a lightweight module 205, which are respectively installed at one end of the telescopic column 203, one end of the downward pressure cylinder 202 is screwed with a connecting seat 206, the other end of the telescopic column 203 is fixedly installed with a spring 207, one end of the spring 207 is fixedly installed with a downward pressure pin 208, and the top of the support frame 201 on the surface of the downward pressure pin 208 is fixedly installed with a guide column 209.

[0036] In this embodiment: a high-pressure module 204 and a lightweight module 205 are provided, wherein the high-pressure module 204 is provided with an enhanced air pressure chamber and a piston with an enlarged area to provide greater downforce, and the lightweight module 205 is made of lightweight materials and has an optimized internal structure to reduce the overall weight and increase the stamping frequency;

[0037] When in use, according to the use requirements, the two sets of downward pressure cylinders 202 can use the same high pressure module 204 or lightweight module 205;

[0038] When a downward pressure operation is required, compressed air enters the downward pressure cylinder 202 through the air inlet, pushing the high pressure module 204 or the lightweight module 205 to move downward. The downward movement of the high pressure module 204 or the lightweight module 205 drives the telescopic column 203 to move downward to perform downward pressure. At the same time, different downward pressures and frequencies can be achieved according to the type of downward pressure module selected.

[0039] The modular design makes maintenance and upgrading simple. For example, when the lightweight module 205 needs to be replaced with the high-pressure module 204, the technician only needs to turn off the gas source, remove the connecting seat 206, and unscrew the bolt 3, and then remove the existing lightweight module 205 and replace it with the high-pressure module 204.

[0040] The guide column 209 is provided, and the guide column 209 is mainly used to play a guiding and limiting role when the push-down ejector pin 208 moves downward.

[0041] Specifically, Figure 4 As shown, the high pressure module 204 and the lightweight module 205 are connected to the telescopic column 203 by means of bolts 3 .

[0042] In this embodiment: the high pressure module 204 and the lightweight module 205 are connected to the telescopic column 203 by means of bolts 3. The high pressure module 204 and the lightweight module 205 can be disassembled by unscrewing the bolts 3.

[0043] Specifically, Figure 4 As shown, the surface of the connection seat 206 is provided with anti-slip textures.

[0044] In this embodiment, by providing anti-skid patterns on the surface of the connection seat 206 , an anti-skid effect can be achieved when the connection seat 206 is manually rotated and disassembled.

[0045] Specifically, Figure 1 As shown, a material dividing mechanism 4 is fixedly installed on the top of the punching needle assembly machine body 1.

[0046] In this embodiment, the needle vibrated out by the vibration plate 5 enters the material distribution mechanism 4 through the pipeline, and then is pushed to the installation hole position by the material distribution push rod, and then is pressed into place by the pressing component 2 at one time.

[0047] Specifically, Figure 1 As shown, a vibration plate 5 is fixedly mounted on the top of the fixed plate 102 .

[0048] In this embodiment, a vibration plate 5 is provided, and the vibration plate 5 is mainly used to place needles, and the needles enter into the material distribution mechanism 4 through the vibration plate 5 .

[0049] Specifically, Figure 1 As shown, a reserved groove 6 is provided on the top of the fixing plate 102 .

[0050] In this embodiment: a reserved groove 6 is provided, and the reserved groove 6 is mainly used for installing the pressing cylinder 202 .

[0051] Specifically, Figure 1 As shown, a switch 7 is installed on the surface of the punch needle assembly machine body 1.

[0052] In this embodiment: a switch 7 is provided, and the switch 7 is mainly used to start the punching needle assembly machine body 1 .

[0053] The specific solution is as follows: the needle vibrated out by the vibration disk 5 enters the distributing mechanism 4 through the pipeline, and then is pushed to the mounting hole position through the distributing push rod. At this time, the compressed air enters the downward pressure cylinder 202 through the air inlet, pushing the high-pressure module 204 or the lightweight module 205 to move downward. The downward movement of the high-pressure module 204 or the lightweight module 205 drives the telescopic column 203 to move downward. The movement of the telescopic column 203 drives the spring 207 and the downward pressure ejector pin 208 to move downward, so that the downward pressure ejector pin 208 enters the inner cavity of the mounting hole. At this time, the spring 207 compresses the downward pressure ejector pin 208, thereby pressing the needle into place at one time. When the lightweight module 205 needs to be replaced with the high-pressure module 204, the technician only needs to turn off the air source, disassemble the connecting seat 206, and unscrew the bolt 3, and then disassemble the existing lightweight module 205 and replace it with the high-pressure module 204.

[0054] A person skilled in the art should understand that the discussion of any of the above embodiments is only exemplary; under the concept of the present invention, the technical features in the above embodiments or different embodiments may be combined, the steps may be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in detail for the sake of simplicity.

[0055] The utility model is intended to cover all such substitutions, modifications and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
