Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, specifically to an injection pen assembly method and system. Background Technology

[0002] An injection pen consists of a pen body and a pen cap. The pen body includes the main body and a measuring device located at the top of the main body. The measuring device can be opened and closed by rotating and raising / lowering relative to the main body. Currently, the assembly method for injection pens is to first place the main body of the pen body on the pen cap, and then assemble the main body and pen cap by pressing down on the measuring device. This assembly method has the following drawbacks: on the one hand, it is easy to damage the measuring device; on the other hand, injection pens are expensive and require high precision in assembly pressure. Because the measuring device has a free amount of rotation and raising / lowering relative to the main body, it cannot accurately measure the assembly pressure during the pressing process, resulting in incomplete assembly or overpressure damage to the injection pen. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an injection pen assembly method and system that avoids pressure damage to the measuring instrument and prevents improper assembly and overpressure damage to the injection pen.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A method for assembling an injection pen includes 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 it;

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

[0009] Rotate the meter relative to the pen body and lower it to the off position.

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

[0011] Before placing the pen body on the pen cap, fill the pen cap with the filling material.

[0012] An injection pen assembly system for implementing the above-described injection pen assembly method includes a conveying device and, sequentially arranged along the conveying device, a pen cap feeding device, an inner filler feeding device, a pen body feeding device, a first metering device screwing device, an assembly device, and a second metering device screwing device. The pen cap feeding device is used to feed the pen cap onto the conveying device, the inner filler feeding device is used to fill the inner filler into the pen cap, the pen body feeding device is used to feed the pen body onto the conveying device, the first metering device screwing device is used to screw open the metering device on the pen body, the assembly device is used to place the pen body on the pen cap and press down the pen body to assemble the pen body and pen cap, and the second metering device screwing device is used to screw close the metering device on the pen body.

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

[0014] The first measuring device includes a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is used to clamp the pen body, and the second clamping mechanism is configured to rotate and lift, and is used to tighten the measuring device.

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

[0016] The lifting and rotating mechanism includes a lifting component and a rotating component, wherein the rotating component is disposed on the lifting component and the second clamping mechanism is disposed on the rotating component.

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

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

[0019] The conveying device is equipped with a carrier, which has a pen body placement slot and a pen cap placement slot.

[0020] The assembly device includes a pre-assembly mechanism and a pressing mechanism. The pre-assembly mechanism is used to place the pen body on the pen cap, and the pressing mechanism is used to press down the pen body to assemble the pen body and pen cap.

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

[0022] The injection pen assembly method of the present invention involves rotating and raising the measuring device relative to the pen body to open it, and then pressing down on the pen body to assemble the pen body and pen cap. In this way, on the one hand, the measuring device is not pressed down on the pen body without being subjected to downward pressure, thus avoiding damage to the measuring device; on the other hand, by opening the measuring device before assembling, the assembly pressure during the assembly process can be recorded more accurately, that is, the assembly pressure during the pressing process can be accurately measured, thereby preventing incomplete assembly and damage to the injection pen due to overpressure.

[0023] The injection pen assembly system of the present invention, on the one hand, does not press down on the pen body through the measuring device, so the measuring device is not subjected to downward pressure and thus avoids damage to the measuring device; on the other hand, the measuring device is opened before assembly during the assembly process, which can record the assembly pressure of the measuring device assembly process. That is, during the pressing process, the assembly pressure during the assembly process can be accurately measured, thereby preventing incomplete assembly and damage to the injection pen due to overpressure.

[0036] Example 1:

[0037] Figure 1 An embodiment of the injection pen assembly method of the present invention is shown. The injection pen assembly method of this embodiment includes the following steps:

[0038] Place the pen body 11 on the pen cap 12, as follows Figure 1 As shown in a4;

[0039] Rotate and raise the measuring device 13 relative to the pen body 11 until it opens, as shown. Figure 1 As shown in a5;

[0040] Press down on the pen body 11 to assemble the pen body 11 and the pen cap 12, as follows: Figure 1 As shown in a6;

[0041] Rotate and lower the meter 13 relative to the pen body 11 to close it, as shown. Figure 1 As shown in a7.

[0042] In this injection pen assembly method, the measuring device 13 is rotated and raised relative to the pen body 11 until it is open, and then the pen body 11 is pressed down to assemble the pen body 11 and the pen cap 12. In this way, on the one hand, the measuring device 13 is not subjected to downward pressure when pressing down on the pen body 11 without passing through the measuring device 13, thus avoiding damage to the measuring device 13; on the other hand, by opening the measuring device 13 before assembling, the assembly pressure of the measuring device 13 during the assembly process can be recorded more accurately. That is, during the pressing process, the assembly pressure during the assembly process can be accurately measured, thereby preventing incomplete assembly and damage to the injection pen due to overpressure.

[0043] The injection pen 1 includes a pen body 11 and a pen cap 12. A measuring device 13 is provided at the top of the pen body 11. The measuring device 13 can be opened and closed by rotating and lifting relative to the pen body 11.

[0044] The order of steps in the injection pen assembly method of this embodiment is as follows:

[0045] S1. Place the pen body 11 on the pen cap 12, with the measuring device 13 facing upwards, as shown. Figure 1 As shown in a4; before placing the pen body 11 on the pen cap 12, align the pen body 11 directly above the pen cap 12, as shown in a4. Figure 1 As shown in a3; before aligning the pen body 11 directly above the pen cap 12, first fill the pen cap 12 with the filling material 14, as shown in Figure a3. Figure 1 As shown in a2; before filling the pen cap 12 with the filling material 14, prepare the pen body 11 and pen cap 12, as follows. Figure 1 As shown in a1.

[0046] S2. Rotate and raise the measuring device 13 relative to the pen body 11 until it is open, as shown. Figure 1 As shown in a5;

[0047] S3, Press down on the pen body 11 to assemble the pen body 11 and the pen cap 12, as follows Figure 1 As shown in a6;

[0048] S4. Rotate and lower the measuring device 13 relative to the pen body 11 until it is closed, as shown. Figure 1 As shown in a7.

[0049] S1 and S2 are interchangeable, meaning that the meter 13 can be rotated and raised relative to the pen body 11 to open first, and then the pen body 11 can be placed on the pen cap 12.

[0050] Furthermore, in this embodiment, before placing the pen body 11 on the pen cap 12, the filler 14 is inserted into the pen cap 12.

[0051] Furthermore, the top periphery of the pen body 11 has a pressure-receiving stepped surface 111 for bearing force when pressed down.

[0052] Example 2:

[0053] Figures 2 to 6 This invention illustrates an embodiment of the injection pen assembly system. This embodiment of the injection pen assembly system is used to implement the injection pen assembly method of Embodiment 1. It includes a conveying device 2, and a pen cap feeding device 3, an inner filler feeding device 4, a pen body feeding device 5, a first metering device 6, an assembly device 7, and a second metering device 8 arranged sequentially along the conveying device 2. The pen cap feeding device 3 feeds the pen cap 12 onto the conveying device 2. The inner filler feeding device 4 fills the inner filler 14 into the pen cap 12. The pen body feeding device 5 feeds the pen body 11 onto the conveying device 2. The first metering device 6 screws open the metering device 13 on the pen body 11. The assembly device 7 places the pen body 11 on the pen cap 12 and presses it down to assemble the pen body 11 and pen cap 12. The second metering device 8 screws close the metering device 13 on the pen body 11.

[0054] The production process of this injection pen assembly system is as follows: First, the pen cap feeding device 3 feeds the pen cap 12 onto the conveying device 2; the conveying device 2 conveys the pen cap 12 to the filling material feeding device 4, which fills the pen cap 14 into the pen cap 12; the conveying device 2 conveys the pen cap 12 to the pen body feeding device 5, which feeds the pen body 11 onto the conveying device 2; the conveying device 2 conveys the pen cap 12 and pen body 11 to the first metering device 6, which screws open the metering device 13 on the pen body 11; the conveying device 2 conveys the pen cap 12 and pen body 11 to the assembly device 7, which places the pen body 11 on the pen cap 12 and presses it down to assemble the pen body 11 and pen cap 12; the conveying device 2 conveys the assembled pen cap 12 and pen body 11 to the second metering device 8, which screws close the metering device 13 on the pen body 11.

[0055] This injection pen assembly system, on the one hand, does not press down on the pen body 11 through the metering device 13, so the metering device 13 is not subjected to downward pressure, thus avoiding damage to the metering device 13; on the other hand, by opening the metering device 13 before assembly, it can record the assembly pressure of the metering device 13 during the assembly process, that is, during the pressing process, it can accurately measure the assembly pressure during the assembly process, thereby preventing incomplete assembly and damage to the injection pen due to overpressure.

[0056] Furthermore, such as Figure 3As shown, in this embodiment, the first measuring device screwing device 6 includes a first clamping mechanism 61 and a second clamping mechanism 62. The first clamping mechanism 61 is used to clamp the pen body 11, and the second clamping mechanism 62 is rotatable and adjustable in height for screwing the measuring device 13. When the first clamping mechanism 61 clamps the pen body 11, the second clamping mechanism 62 can clamp the measuring device 13 on the top of the pen body 11 and rotate upward to open the measuring device 13. Conversely, when the second clamping mechanism 62 clamps the measuring device 13 on the top of the pen body 11, it rotates downward to close the measuring device 13. The structure is reasonably designed and easy to operate.

[0057] Furthermore, in this embodiment, the first measuring instrument turning device 6 also includes a lifting and rotating mechanism 63, and a second clamping mechanism 62 is disposed on the lifting and rotating mechanism 63. The lifting and rotating mechanism 63 drives the second clamping mechanism 62 to rotate and move up and down.

[0058] Furthermore, such as Figure 4 and Figure 5 As shown, in this embodiment, the lifting and rotating mechanism 63 includes a lifting component 631 and a rotating component 632. The rotating component 632 is disposed on the lifting component 631, and the second clamping mechanism 62 is disposed on the rotating component 632. The rotating component 632 can drive the second clamping mechanism 62 to rotate and move up and down with the lifting component 631.

[0059] Furthermore, such as Figure 5 As shown, in this embodiment, the first clamping mechanism 61 is horizontally movable to facilitate the clamping and placement of the vertically transported pen body 11.

[0060] Furthermore, in this embodiment, the second measuring instrument tightening device 8 has the same structure as the first measuring instrument tightening device 6. This facilitates standardized production and saves design and production costs.

[0061] Furthermore, such as Figure 6 As shown, in this embodiment, the conveying device 2 is provided with a carrier 21, and the carrier 21 is provided with a pen body placement slot 211 and a pen cap placement slot 212. The pen body placement slot 211 is used to place the pen body 11, and the pen cap placement slot 212 is used to place the pen cap 12.

[0062] Furthermore, such as Figure 2 As shown, in this embodiment, the assembly device 7 includes a pre-assembly mechanism 71 and a pressing mechanism 72. The pre-assembly mechanism 71 is used to place the pen body 11 on the pen cap 12, and the pressing mechanism 72 is used to press down the pen body 11 to assemble the pen body 11 and the pen cap 12. The pre-assembly mechanism 71 first places the pen body 11 on the pen cap 12, and then the pressing mechanism 72 presses down the pen body 11 to assemble the pen body 11 and the pen cap 12, which improves the success rate of assembly and avoids incomplete assembly due to misalignment, thereby preventing product damage.

[0063] Furthermore, the top periphery of the pen body 11 has a pressure-receiving step surface 111, and when the pressing mechanism 72 presses down on the pen body 11, it presses on the pressure-receiving step surface 111.

[0064] While the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the invention. Any person skilled in the art can make many possible variations and modifications to the technical solutions of the present invention, or modify them into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the scope of the present invention, should fall within the protection scope of the present invention.
