[0022] A large circular knitting machine precision needle cylinder manufacturing process, the process uses the large circular knitting machine precision needle cylinder manufacturing system assembly line.

[0023] The limiting ring 108 refers to a ring-shaped component that plays a limiting role. The limiting rings 108 of different diameters are suitable for syringes of different diameters. The purpose of setting it is to facilitate the placement of the syringe so that the syringe can be placed in the center of the circular box seat 101.

[0024] The magnetic core 303 refers to a core-shaped component composed of a magnet, and its purpose is to attract metal powder that can be attracted by the magnet, thereby further improving the dust collection effect.

[0025] The milling cutter 4 refers to a component in the prior art that performs a milling function. Technicians can select and replace milling cutters with different cutter head shapes according to actual needs.

[0026] The polishing rod 5 refers to a rod-shaped component with a polishing layer on the surface for polishing. This description is clear enough and will not cause misunderstanding among technicians. There is no problem of ambiguity in the description. The polishing layer here can be made of different materials such as corundum, emery cloth, wool, etc. according to the polishing accuracy requirements. It is not the content to be protected by the applicant and therefore will not be further disclosed.

[0027] The electric-controlled robotic arm 202 refers to a high-precision, multi-input, multi-output, and strongly coupled device in the prior art. It belongs to the prior art content, so the specific structure and working principle will not be further described.

[0028] The control method of the present invention is to achieve automatic control through an external controller. Each electrical component is connected to and controlled by the controller. The control circuit of the controller can be implemented by simple programming by a person skilled in the art. The provision of power is also common knowledge in the art. The present invention is mainly used to protect mechanical devices, so the control method and circuit connection are not explained in detail in the present invention.

[0029] The working principle of the present invention is: the syringe is placed on the top surface of the circular box seat 101, and the linear motor 103 is started so that the mover of the linear motor 103 drives the slider 102 to move along the slide groove 106. Each slider 102 will clamp the side of the syringe to prevent the syringe from being displaced or rotated during the processing. The limit ring 108 cooperates with the slider 102 moving toward the center of the circular box seat 101 to help quickly fix the syringe in the center of the circular box seat 101.

[0030] The annular mounting plate 105 can rotate on the circular box seat 101 and the servo motor 201 is installed on the annular mounting plate 105. Therefore, the rotation of the servo motor 201 drives the transmission gear 204 to engage with the ring gear 104, which can drive the annular mounting plate 105 to rotate on the circular box seat 101. Cooperating with the electric-controlled robotic arm 202, the milling cutter 4 and the grinding rod 5 can perform milling and grinding operations on different parts of the syringe. Holes and grooves can be milled and polished on the syringe. While the milling cutter 4 on one mobile device 2 is milling, the grinding rod 5 on another mobile device 2 can grind the holes and grooves, which helps to improve processing efficiency.

[0031] The column 301 is set at the center of the circular box base 101. After the connecting pipe 302 is connected to the suction equipment, a negative pressure will be formed at the through hole 304 on the column 301, which will help to suck the powder formed during the grinding process into the column 301, so as to prevent the powder from affecting the grinding accuracy of the syringe. At the same time, the air and powder are sucked into the column 301 to drive the air flow, which can cool the syringe.

[0032] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
