[0002] An insulin pen is a medical device used to inject insulin into diabetic patients. Due to its accurate dosage, ease of use, and portability, it has become a commonly used injection tool for many diabetic patients. However, the assembly process of an insulin pen involves several precision components, including the upper pen shell assembly, the lower pen shell assembly, and the pre-filled cartridge (PFS). The assembly process is complex and requires high precision. Traditional assembly methods rely heavily on manual operation, which is not only inefficient but also prone to problems such as poor assembly and damage to components, resulting in a low product yield.

[0003] The upper and lower pen shell assemblies need to be precisely aligned and fit tightly to ensure the overall structure and sealing of the insulin pen. The PFS is the core component of the insulin pen, and its pressing process requires strict control of force and position to ensure that the pen cartridge can be accurately fixed inside the pen shell and will not loosen or leak during use.

DETAILED DESCRIPTION

[0030] The present invention will be further described in detail below with reference to specific embodiments:

[0031] like Figures 1-6 As shown, a four-station semi-automatic assembly machine includes a material support platform 1, a moving module 2, a PFS pressing module 3, and an upper pen shell assembly pressing module 4. A first support part 11, a second support part 12, and a third support part 13 are sequentially arranged along the forward direction of the material support platform 1. The first support part 11 includes a pair of grippers 111 and a linear guide rail 112. The pair of grippers 111 are located on both sides of the lower pen shell assembly 5 and mounted on the linear guide rail 112. The linear guide rail 112 drives the pair of grippers 111 to clamp or release the lower pen shell assembly 5, realizing pressing and material replacement. The first support part 11 and the third support part 13 are respectively provided with mounting holes 10. The PFS 6 and the upper pen shell assembly 7 are respectively placed in the corresponding mounting holes 10. During the pressing of the pen shell assembly 7, the material support platform 1 moves under the drive of the moving module 2. First, the PFS6 is moved to the PFS pressing module 3. The PFS pressing module 3 moves downward to remove the PFS6 from the second support part 12 and return it to the initial position. Then, the lower pen shell assembly 5 moves to the PFS pressing module 3. The PFS pressing module 3 presses the PFS6 onto the lower pen shell assembly 5. Then, the upper pen shell assembly 7 is moved to the upper pen shell assembly pressing module 4. The upper pen shell assembly pressing module 4 moves downward to clamp the upper pen shell assembly 7 and moves it back to the initial position. After the lower pen shell assembly 5 moves to the upper pen shell assembly pressing module 4, the upper pen shell assembly 7 is pressed onto the lower pen shell assembly 5, thus completing the pressing of the upper pen shell assembly 7, PFS6, and lower pen shell assembly 5.

[0032] In this embodiment, as Figures 2-6 As shown, multiple PFS pressing modules 3 and multiple upper pen shell assembly pressing modules 4 are arranged in an array along the length of the material support platform 1. When the material support platform 1 moves to the position below the corresponding PFS pressing module 3 and upper pen shell assembly pressing module 4, the positions of the PFS pressing module 3 and upper pen shell assembly pressing module 4 correspond one-to-one with the positions of the first support part 11, the second support part 12, and the third support part 13. By arranging multiple modules in an array, more products can be produced in the same amount of time, thereby improving production efficiency. At the same time, due to the independence between modules, even if one module fails, it will not affect the normal operation of other modules, thus ensuring the continuity and stability of production. Furthermore, since the modules are arranged in an array along the length of the material support platform 1, the number and position of the modules can be flexibly adjusted according to production needs, which can adapt to the production needs of products of different sizes and shapes.

[0033] When the PFS6 and the upper pen shell assembly 7 are pressed, the PFS pressing assembly 3 is pressed first, so as not to increase the pressing time of the material carrying table 1 moving back and forth on the moving module 2, the PFS pressing assembly 3 and the upper pen shell assembly pressing assembly 4 are arranged in sequence along the advancing direction of the material carrying table 1, and are located above the moving module 2, the upper pen shell assembly 7 and the PFS6 reach the lower side of the PFS pressing assembly 3 in sequence during the movement of the material carrying table 1, after the PFS6 is clamped, the material carrying table 1 continues to move in one direction, the lower pen shell assembly 5 moves to the lower side of the PFS pressing assembly 3, at this time, the pressing of the PFS6 is completed, and the clamping of the upper pen shell assembly 7 is also completed, or when the upper pen shell assembly 7 moves to the lower side of the upper pen shell pressing assembly 3 to complete the clamping of the upper pen shell assembly 7, finally, the lower pen shell assembly 5 moves to the lower side of the upper pen shell assembly pressing assembly 4 to complete the pressing, during the pressing process, the material carrying table 1 always moves in the advancing direction, greatly reducing the clamping and pressing time wasted by reciprocating movement.

[0034] Further, the PFS pressing assembly 3 comprises a first driving device 31 and a first electric clamp jaw 32, the top of the first electric clamp jaw 32 is connected to the driving end of the first driving device 31, the upper pen shell assembly pressing assembly 4 comprises a second driving device 41 and a second electric clamp jaw 42, the second electric clamp jaw 42 is connected to the driving end of the second driving device 41, wherein the clamping part of the first electric clamp jaw 32 matches the top side wall of the PFS6, and the clamping part of the second electric clamp jaw 42 matches the top side wall of the upper pen shell assembly 7, the first driving device 31 and the second driving device 41 are responsible for driving the first electric clamp jaw 32 and the second electric clamp jaw 42 to move respectively, the first driving device 31 and the second driving device 41 can provide stable and controllable power output, ensuring that the first electric clamp jaw 32 and the second electric clamp jaw 42 can accurately and quickly reach the specified position, reducing manual intervention through the automatic pressing assembly 3, improving production efficiency, and realizing rapid and continuous pressing operation through precise control of the movement of the driving device and the electric clamp jaw 111.

[0035] As Figures 5-6As shown, in order to prevent the position of the lower pen shell assembly 5 from being inaccurate during the pressing process or the pressure being too large during the pressing, causing the pen shell assembly to be damaged and broken, a pressure sensor 8 is arranged at the connecting position of the first driving device 31 and the first electric clamp jaw 32, a pressure sensor 8 is arranged at the connecting position of the second driving device 41 and the second electric clamp jaw 42, and a positioning block 9 is installed below the first support part 11 and corresponds to the preset position of the lower pen shell assembly 5. The arrangement of the pressure sensor 8 can monitor the pressure change of the electric clamp jaw 111 during the pressing process in real time, and when the pressure exceeds the preset value, the pressure sensor 8 will send a signal to stop the pressing operation in time, thereby preventing the pen shell assembly from being damaged due to excessive pressure. The installation of the positioning block 9 can ensure the position accuracy of the lower pen shell assembly 5 during the pressing process. The positioning block 9 corresponds to the preset position of the lower pen shell assembly 5, so that the pressing operation is more accurate, and the failure of the pressing or the damage of the pen shell assembly caused by inaccurate position is avoided.
