Problems solved by technology

The biggest disadvantage of manual testing and screening is that the syringe is easy to attach germs, which will inevitably pollute the needle seat during the testing process, resulting in unqualified product hygiene requirements
On the other hand, the speed of manual operation is also low, and it is difficult to adapt to the fierce market competition.
There are also attempts to design a detection device for safe self-destructing syringes, but the stability of the work is not high, and there is also a lack of follow-up operations such as eliminating defective products after the detection is completed.

Embodiment 1

[0037] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0038]As shown in Figures 1 and 2, the detection system of the safety self-destructing syringe assembly machine includes a rotating shaft 1, a turntable 2, a detection device 5, an exclusion device 7, a control system 8, a pressure control device 54, and a sensor 9. .

[0039] As shown in Figure 2, the detection system is set on a safety self-destruct syringe assembly machine. It includes a rotating shaft 1 on which a turntable 2 that can rotate together with the rotating shaft 1 is fixed, and several notches 2a for fixing the cylinder 3 are evenly distributed on the edge of the turntable 2 . Below the notch 2a is provided a defective product detection device 5 for applying an upward force to the needle holder 4 installed...

Embodiment 2

[0047] As shown in Figures 5 and 6, in this embodiment, the pressure control device 54 is a spring 54a, one end of the spring 54a acts on the top block 52, and the other end acts on the elevating frame 53b. The rest are the same as in Example 1, and will not be described in detail herein.

Embodiment 3

[0049] As shown in Figures 7 and 8, in this embodiment, the lifting mechanism 53 includes a servo motor 53c fixed on the bracket 51, and the motor shaft of the servo motor 53c is fixedly connected with a screw rod 53d through a coupling 53f , on the screw rod 53d, a vertical moving block 53e is threadedly connected, the above-mentioned top block 52 is fixedly connected on the vertical moving block 53e, and the top block 52 is provided with a mechanism for controlling the force of the top block 52 on the needle hub 4 Pressure control device 54. The pressure control device 54 is a pressure sensor 54b, and its working principle is that when the silicon piezoresistive element is bent and deformed by an external force, the resistance will change accordingly, thereby adjusting the rotation speed of the servo motor 53c. The moving speed of the lifting mechanism 53 is controlled by adjusting the servo motor 53c through the force touched by the pressure sensor 54b. The servo motor 53c...

Abstract

The invention provides a detection system of safe selfdestruction injector assembling machine and belongs to technology field of medical appliance production machine. It solves the problem of inefficiency and insalubrity in present detection system of safe selfdestruction type injector assembling machine caused by manual operation. The detection system of safe selfdestruction type injector assembling machine comprises a rotor shaft, a rotor plate fixed on the rotor shaft and capable rotating with the rotor shaft, notches uniformly distributed at the edge of the rotor plate and used for fixing cylinder, detection device arranged under the notches and used for detecting quality, a stopper arranged above the the notches and used for blocking cylinder and preventing jacking, and a remover arranged beside the detection device and used for expelling bad products from notches, wherein the detection device and remover are connected with the control system of the assembling machine. The device has the advantages of high detecting efficiency, high safety, good sanitation, stable and reliable working performance, and good compatibility.

Description

technical field [0001] The invention relates to the field of medical device production devices, in particular to a detection system for a safe self-destruction syringe assembly machine. Background technique [0002] In the medical sector, disposable syringes have been widely used due to their convenience, safety and hygiene. When using a disposable syringe, the syringe does not need to be sterilized, and the user only needs to tear off the outer package directly. In order to prevent criminals from recycling used syringes, people have designed self-destructing syringes. After the syringe is used once, the two disengage when the injection lever pulls the rubber stopper back, making it unusable. At the same time, in order to prevent the needle of the disposable syringe from hurting the recycling personnel when handling medical waste, people have further designed a safe self-destructing syringe. This syringe can not only make the injection rod and the rubber stopper disengage...
