[0002] In the medical field, biocompatibility is a crucial characteristic because it is directly related to the compatibility of medical devices with human tissues, as well as the health and safety of patients. Therefore, when manufacturing medical devices and instruments, the plastic materials used must meet strict biocompatibility standards. Plastics, especially thermoplastic materials such as polyethylene (PE), polyvinyl chloride (PVC), polypropylene (PP) and polycarbonate (PC), are often selected for the manufacture of various components in medical devices, such as infusion sets, surgical instruments and medical packaging, due to their high transparency, good chemical resistance and good processing performance.

[0003] However, these thermoplastic materials behave differently during welding. For example, the welding temperature of PE and PVC is lower than that of PP and PC. If the same welding parameters are used for welding, the heat deformation temperature of PE and PVC materials may exceed their heat resistance, causing a decrease in material performance. Conversely, if the welding parameters are set for PP and PC, PE and PVC may not achieve good welding results. Therefore, in order to ensure welding quality, specific welding parameters need to be set for each material, which requires a large amount of test data to improve the accuracy of welding parameters.

Compared with conventional test equipment at this stage, the present application has the advantages of high flexibility of use, wide range of applications, small size, low assembly cost and strong compatibility.

[0026] See also Figure 1 and Figure 2As shown, this embodiment is used to perform welding test on a square thermoplastic transparent PE test plate 130. The mounting mechanism 100 is used to provide an installation base and a working space for the lifting mechanism 200. It specifically includes four guide pillars 120. The four guide pillars 120 respectively support the four corners of the test plate 130. In other embodiments, the number and setting position of the guide pillars 120 can be adjusted according to actual use requirements, and the utility model does not impose specific restrictions on this. Furthermore, the installation mechanism 100 in this embodiment further includes a base plate 110, the test plate 130 and the base plate 110 are respectively arranged at the two ends of the guide column 120, and the base plate 110 is used to provide a fixing surface for the guide column 120, so that the installation structure of the guide column 120 is stable and firm. In this embodiment, a plug-in hole is provided on the base plate 110, one end of the guide column 120 is inserted on the base plate 110, and the other end is inserted on the test plate 130. Specifically, the guide column 120 includes a guide portion 121 and a positioning portion 122, and the positioning portion 122 is arranged at the end of the guide portion 121. A positioning hole is provided on the test plate 130, and the positioning portion 122 is inserted in the positioning hole. The lifting plate 230 is slidably sleeved on the guide portion 121. Based on this structural setting, the guide column 120 can be stably connected to the base plate 110 and the test plate 130, and the stability and efficiency of the welding test process can be ensured.

[0027] See also Figure 1 and Figure 2 As shown, the test board 130 includes a body 131 and a welding body 132, wherein the welding body 132 is located in the middle of the body 131, and the component to be tested is welded to the welding body 132. During the test, since the components to be tested may have different models or sizes, for small components to be tested, a through hole can be set in the center of the body 131 of the test board 130 to connect the welding body 132. Based on this structure, during the test, the body 131 can be welded and tested, or the body 131 can be used as a connecting element to weld the welding bodies 132 with different centers, thereby improving the flexibility of the use of the device.

[0028] See also Figure 1 and Figure 2As shown, the lifting mechanism 200 in this embodiment is used to realize the lifting and moving of the components to be welded. When the components are placed and installed, the lifting assembly is located at the bottom of the device to provide space for the components to be placed and installed; when the components to be welded need to contact the test board 130, the welded components can be moved toward the test board 130 to make the two contact. Specifically, the lifting mechanism 200 in this embodiment also includes a driving member 210, and the driving member 210 is connected to one side of the follower block 220 in the horizontal direction to drive the follower block 220 to move horizontally. Specifically, the driving member 210 in this embodiment includes a driver 211 and a mounting frame 212, and the mounting frame 212 is arranged on one side of the mounting mechanism 100. The driver 211 is preferably a driving motor extending in the horizontal direction, which transmits the driving force to the follower block 220. The driving member 210 in this embodiment achieves the effect of converting the horizontal drive into the lifting drive through a reasonable layout, thereby reducing the overall space of the device. In this embodiment, the follower block 220 is preferably a right-angled triangular pyramid element placed sideways, with its inclined surface facing the test board 130, see Figure 2 As shown, in this embodiment, when the driving motor is in a stationary state, the lifting wheel 240 is located at the bottom of the follower block 220. When the driving member 210 is started, the follower block 220 gradually moves under its driving action, and the lifting wheel 240 gradually moves toward the test plate 130 along the upper surface of the follower block 220, thereby driving the lifting plate 230 and the carrier 260 connected thereto to move synchronously to complete the lifting operation process. Among them, the lifting mechanism 200 also includes a connecting frame 250, and the lifting wheel 240 is connected to the lifting plate 230 through the connecting frame 250, thereby improving the connection strength between the lifting wheel 240 and the lifting plate 230 on the one hand, and providing an escape space for the rolling process of the lifting wheel 240 on the other hand, so as to avoid the occurrence of the lifting wheel 240 jamming and the like.
