[0030] 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.
[0031] Please see Figure 1-4 This utility model provides a technical solution:
[0032] An assembly device for sealing rubber plugs and needle tubes for indwelling needles includes:
[0033] The base plate 1 has a first cylinder 2 fixedly connected to its upper end. A first movable frame 3 is fixedly connected to the output end of the first cylinder 2. The first movable frame 3 is provided with a clamping component 4 for clamping the sealing plug inside.
[0034] The upper end of the base plate 1 is provided with a punching assembly for punching holes in the sealing plug;
[0035] A second electric actuator 10 is fixedly connected to the upper end of the base plate 1, and a collection component 11 for collecting the waste material after drilling is provided on the output end of the second electric actuator 10.
[0036] The upper end of the base plate 1 is provided with an indwelling needle body 15, and the upper end of the base plate 1 is provided with a moving mechanism for controlling the movement of the indwelling needle body 15.
[0037] For example, the base plate 1 serves as the supporting foundation for the entire device, providing a stable installation platform for other components. The first cylinder 2, as one of the power sources, can generate linear reciprocating motion at its output end. The first moving frame 3 is an important structure that supports the clamping assembly 4. It moves with the movement of the output end of the first cylinder 2. The clamping assembly 4 can accurately clamp the sealing plug, ensuring that the position of the sealing plug is accurate during subsequent assembly. The drilling assembly is a key part of the device that realizes the function of drilling the sealing plug. The second electric push rod 10 is also a power device that can provide linear motion. The design of the collection assembly 11 can effectively collect waste materials, keep the working environment clean, and also facilitate the recycling and treatment of waste materials, meeting environmental protection requirements. The function of the moving mechanism is to enable the indwelling needle body 15 to move within the working area of the device according to a predetermined trajectory and position, so as to accurately assemble with other components such as the sealing plug. By accurately controlling the movement of the indwelling needle body 15, the accuracy and efficiency of assembly can be improved, and the error of manual operation can be reduced.
[0038] The clamping assembly 4 includes a first electric push rod 41, a lifting plate 42, an upper clamping block 43, and a lower clamping block 44;
[0039] The first movable frame 3 is internally fixedly connected to a first electric push rod 41, and a lifting plate 42 is fixedly connected to the output end of the first electric push rod 41. An upper clamping block 43 is bolted to the side wall of the lifting plate 42, and a lower clamping block 44 is bolted to the side wall of the first movable frame 3. The lower clamping block 44 is in contact with the upper clamping block 43.
[0040] For example, a lifting plate 42 is fixedly connected to the output end of the first electric actuator 41. The lifting plate 42 is made of high-strength metal sheet and its surface is precision machined to ensure a firm connection with the upper clamping block 43. The shape and size of the upper clamping block 43 are designed according to the shape of the sealing plug to ensure that it can fit tightly against the upper surface of the sealing plug. The lower clamping block 44 is arranged opposite to the upper clamping block 43. When the first electric actuator 41 drives the lifting plate 42 to descend, the upper clamping block 43 and the lower clamping block 44 come into contact with each other, thereby firmly clamping the sealing plug between them.
[0041] The upper end of the base plate 1 is fixedly connected to the first guide rail 5, and the first guide rail 5 is slidably connected to the first movable frame 3.
[0042] For example, a first guide rail 5 is fixedly connected to the upper end of the base plate 1. The first guide rail 5 is a high-precision linear guide rail with good guiding performance and wear resistance. The first guide rail 5 is slidably connected to the first movable frame 3. The first movable frame 3 cooperates with the first guide rail 5 through components such as sliders, so that the first movable frame 3 can only move in a straight line along the direction of the first guide rail 5, avoiding deviation and shaking during the movement, thereby improving the accuracy of the clamping assembly 4 in clamping the sealing plug.
[0043] The punching assembly includes a second cylinder 6, a second moving frame 7, a second guide rail 8, and a punch 9;
[0044] The base plate 1 is fixedly connected to the upper end of the second cylinder 6, the output end of the second cylinder 6 is fixedly connected to the second moving frame 7, the second moving frame 7 is slidably connected to the second guide rail 8, the second guide rail 8 is fixedly connected to the base plate 1, and the upper end of the second moving frame 7 is bolted with a punch 9.
[0045] For example, the second cylinder 6 is fixedly connected to the upper end of the base plate 1, providing power for the drilling operation. A second movable frame 7 is fixedly connected to the output end of the second cylinder 6. The second movable frame 7 is a structure that carries the punching knife 9. A second guide rail 8 is slidably connected inside the second movable frame 7. The second guide rail 8 is also fixedly connected to the base plate 1. The function of the second guide rail 8 is to guide the movement direction of the second movable frame 7 and ensure the straightness and stability of the second movable frame 7 during movement. The punching knife 9 is bolted to the upper end of the second movable frame 7. The punching knife 9 is a component that directly punches holes in the sealing plug. Its material is usually selected from high-hardness and high-wear-resistant alloy materials to ensure the quality and efficiency of punching. When the second cylinder 6 works, its output end pushes the second movable frame 7 to move along the second guide rail 8, thereby driving the punching knife 9 to punch holes in the sealing plug.
[0046] The collection component 11 includes a mounting frame 111, a slider 112, a collection frame 113, a filter plate 114, a filter disc 115, a fan 116, and a sealing plate 117.
[0047] The second electric actuator 10 is fixedly connected to an installation frame 111. A slider 112 is snapped into the inside of the installation frame 111. A collection frame 113 is fixedly connected to the side wall of the slider 112. The collection frame 113 contacts the upper clamping block 43 and the lower clamping block 44 respectively. The collection frame 113 is slidably connected to the installation frame 111. A filter plate 114 and a filter disc 115 are fixedly connected inside the collection frame 113 respectively. A fan 116 is fixedly connected to the side wall of the collection frame 113. A sealing plate 117 is bolted to the lower end of the collection frame 113.
[0048] For example, the mounting frame 111 serves as the basic support structure for the collection assembly 11, providing installation positions for other components. A slider 112 is snapped into the interior of the mounting frame 111. The design of the slider 112 allows for easy installation and removal of the collection frame 113. The collection frame 113 is fixedly connected to the side wall of the slider 112. The collection frame 113 contacts the upper clamping block 43 and the lower clamping block 44 respectively, allowing waste generated during the drilling process to fall directly into the collection frame 113. The collection frame 113 is slidably connected to the mounting frame 111, facilitating its removal and cleaning. The filter plate 114 filters the waste entering the collection frame 113. The air is filtered, which also facilitates air entry into the collection frame 113, preventing the blower 116 from lacking an air inlet and failing to work properly. The filter disc 115 prevents fine particles in the waste from entering the blower 116, protecting the normal operation of the blower 116. The blower 116 is fixedly connected to the side wall of the collection frame 113. When the blower 116 is working, it will generate negative pressure in the collection frame 113, thereby sucking the waste generated during the drilling process into the collection frame 113. A sealing plate 117 is bolted to the lower end of the collection frame 113. The sealing plate 117 can prevent the waste in the collection frame 113 from leaking out, and can also easily clean out the collected waste.
[0049] The moving mechanism includes a third cylinder 12, a third moving frame 13, a third guide rail 14, and a pressing assembly 16;
[0050] The upper end of the base plate 1 is fixedly connected to a third cylinder 12, and the output end of the third cylinder 12 is fixedly connected to a third moving frame 13. The third moving frame 13 is in contact with the indwelling needle body 15. The interior of the third moving frame 13 is slidably connected to a third guide rail 14, which is fixedly connected to the base plate 1. The upper end of the third moving frame 13 is provided with a pressing component 16 for fixing the indwelling needle body 15.
[0051] For example, the third cylinder 12 is fixedly connected to the upper end of the base plate 1. It is the power source for driving the indwelling needle body 15 to move. The third moving frame 13 is a structure that carries the indwelling needle body 15 and the pressing component 16. The movement of the third moving frame 13 drives the indwelling needle body 15 to move. The function of the third guide rail 14 is to guide the movement direction of the third moving frame 13 and ensure the stability and accuracy of the third moving frame 13 during the movement. The pressing component 16 can fix the indwelling needle body 15 on the third moving frame 13 during the movement to prevent the indwelling needle body 15 from shaking or displacing.
[0052] The pressing assembly 16 includes a fixing frame 161, a third electric push rod 162, and a pressing plate 163;
[0053] Among them, the upper end of the third moving frame 13 is fixedly connected to the fixed frame 161, the inside of the fixed frame 161 is fixedly connected to the third electric push rod 162, the output end of the third electric push rod 162 is fixedly connected to the lower pressure plate 163, and the lower pressure plate 163 is in contact with the indwelling needle body 15.
[0054] For example, the mounting bracket 161 provides an installation position for the third electric push rod 162, which is the power source for the pressing assembly 16. When the third electric push rod 162 is working, its output end pushes the pressing plate 163 downward, thereby pressing the indwelling needle body 15 tightly onto the third moving bracket 13 to fix the indwelling needle body 15. After the indwelling needle body 15 moves to the designated position, the third electric push rod 162 drives the pressing plate 163 upward to release the indwelling needle body 15 so as to carry out subsequent assembly operations.
[0055] Working principle: When the equipment is started, the first cylinder 2 pushes the first moving frame 3 to the designated position, and the first electric push rod 41 works. Its output end drives the lifting plate 42 to descend, thereby causing the upper clamping block 43 and the lower clamping block 44 to come into contact with each other and firmly clamp the sealing plug between the two.
[0056] After the sealing plug is clamped, the second cylinder 6 works, and its output end pushes the second moving frame 7 to move along the second guide rail 8, which drives the punch 9 to move towards the sealing plug, thereby realizing the punching operation of the sealing plug to meet the usage requirements of the indwelling needle.
[0057] Waste is generated during the drilling process. The collection component 11 is used to effectively collect this waste. The blower 116 operates, generating negative pressure inside the collection frame 113, which draws the waste generated during the drilling process into the collection frame 113. The sealing plate 117 bolted to the lower end of the collection frame 113 prevents waste leakage and facilitates the cleaning of the collected waste.
[0058] After drilling is completed, the first cylinder 2 continues to drive the first moving frame 3 to move. The third electric push rod 162 works, and its output end pushes the lower pressure plate 163 downward to press the indwelling needle body 15 tightly onto the third moving frame 13. Then, the third cylinder 12 works, and its output end pushes the third moving frame 13 to move along the third guide rail 14. The indwelling needle body 15 is inserted into the holed sealing plug. After assembly, the first electric push rod 41 retracts to release the limit on the sealing plug. The third electric push rod 162 also retracts to release the limit on the indwelling needle body 15, making it easier to remove the assembled workpiece.
[0059] The control method of the first cylinder 2, the first electric actuator 41, the second cylinder 6, the second electric actuator 10, the third cylinder 12, and the third electric actuator 162 in this application is automatic control by a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Furthermore, this application is mainly used to protect the structure, shape, and their combination, so this application will not explain the control method and circuit connection in detail. The device is powered by a built-in power supply or an external power supply.
[0060] 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.
