Description

Technical Field

[0001] The invention relates to the technical field of food and medicine packaging machinery and equipment, and in particular to an injection pen assembly method and an injection pen assembly system. Background Art

[0002] The injection pen includes a pen body and a pen cap. The pen body includes a pen body main body and a meter arranged at the top of the pen body main body. The meter can be rotated and raised relative to the pen body main body to be opened and closed. At present, the assembly method of the injection pen is to first place the pen body of the pen on the pen cap, and then assemble the pen body main body and the pen cap by pressing down the meter. This assembly method has the following disadvantages: on the one hand, it is easy to damage the meter; on the other hand, the injection pen is expensive and requires high precision of assembly pressure. Since the meter has the freedom to rotate and rise relative to the pen body main body, the assembly pressure in the assembly process cannot be accurately measured during the pressing process, resulting in improper assembly and over-pressure damage to the injection pen. Summary of the invention

[0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide an injection pen assembly method and an injection pen assembly system which can avoid pressure damage to the meter, prevent improper assembly and damage to the injection pen due to overpressure.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] An injection pen assembly method comprises the following steps:

[0006] Place the pen body on the pen cap;

[0007] Rotate and raise the meter relative to the pen body to open;

[0008] Press down the pen body to assemble the pen body and pen cap;

[0009] Rotate and lower the gauge relative to the pen body to close.

[0010] As a further improvement of the above technical solution:

[0011] Before placing the pen body on the cap, put the liner into the cap.

[0012] An injection pen assembly system is used to implement the above-mentioned injection pen assembly method, comprising a conveying device, and a pen cap loading device, an inner filling loading device, a pen body loading device, a first metering device screwing device, an assembling device and a second metering device screwing device arranged in sequence along the conveying device, the pen cap loading device is used to load the pen cap onto the conveying device, the inner filling loading device is used to load the inner filling into the pen cap, the pen body loading device is used to load the pen body onto the conveying device, the first metering device screwing device is used to screw open the meter on the pen body, the assembling device is used to place the pen body on the pen cap and press down the pen body to assemble the pen body and the pen cap, and the second metering device screwing device is used to screw close the meter on the pen body.

[0013] As a further improvement of the above technical solution:

[0014] The first meter screwing device includes a first clamping mechanism and a second clamping mechanism, wherein the first clamping mechanism is used to clamp the pen body, and the second clamping mechanism is arranged to rotate and rise and fall and is used to screw the meter.

[0015] The first meter screwing device also includes a lifting and rotating mechanism, and the second clamping mechanism is arranged on the lifting and rotating mechanism.

[0016] The lifting and rotating mechanism comprises a lifting component and a rotating component. The rotating component is arranged on the lifting component, and the second clamping mechanism is arranged on the rotating component.

[0017] The first clamping mechanism is arranged to move horizontally.

[0018] The second meter screwing device has the same structure as the first meter screwing device.

[0019] The conveying device is provided with a carrier, and the carrier is provided with a pen body placement groove and a pen cap placement groove.

[0020] The assembling device comprises a pre-assembling mechanism and a pressing mechanism, wherein the pre-assembling mechanism is used to place the pen body on the pen cap, and the pressing mechanism is used to press the pen body downward to assemble the pen body and the pen cap.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] The injection pen assembling method of the present invention rotates and raises the meter relative to the pen body to open it, and then presses down on the pen body to assemble the pen body and the pen cap. In this way, on the one hand, the pen body is not pressed down by the meter, and the meter is not subjected to the downward pressure, thereby avoiding damage to the meter. On the other hand, during the assembly process, the meter is first opened and then assembled, which can better record the assembly pressure of the meter during the assembly process, that is, during the pressing process, the assembly pressure during the assembly process can be accurately measured, thereby preventing improper assembly and over-pressure damage to the injection pen.
