Description

Technical Field

[0001] The present invention relates to the field of coating technology for dynamic blood glucose sensor probes, and more particularly to an automatic coating device for sensors and a coating method using the device. Background Art

[0002] The dynamic blood glucose monitoring system (RGMS) is a new type of continuous dynamic blood glucose monitoring system that has been put into clinical use in recent years. It is connected to a probe similar to a needle, which is used to be inserted into the subcutaneous tissue. The diameter of the probe is very small, and the patient does not feel obvious pain or discomfort when inserted. The instrument receives an electrical signal reflecting blood sugar changes from the probe once at a certain interval, and converts the average value of the electrical signals collected multiple times into a blood sugar value and stores it. Hundreds of blood sugar values can be recorded every day. The dynamic blood glucose monitor can also store the time of meals, exercise, medication, etc. at the same time. This means that patients no longer have to endure the pain of needle pricks every day, and it can provide daily blood sugar graphs, multi-day blood sugar graph fluctuation trend analysis and a summary of daily blood sugar data. It is a new breakthrough in blood sugar testing.

[0003] The sensor probe needs to undergo a coating process on the needle tip, and the coating process includes overcoating and dipping. A balancing process is required before and after the overcoating process, so that the sensor needs to flow between different workstations and also needs to be loaded and unloaded. In order to ensure the quality of the sensor, the overcoating and balancing processes need to be carried out in a sealed environment. Therefore, it is urgent to design an automatic sensor overcoating equipment to realize the automatic and orderly coating of the sensor in a closed environment to ensure that the sensor coating process is smooth and stable. Summary of the Invention

[0004] In response to the shortcomings of the prior art, the present invention provides an automatic sensor coating equipment and a coating method using the equipment. The automatic sensor coating equipment of the present invention adopts a coating balance flow platform to realize the flow between the first balance bin, the coating bin and the second balance bin inside the coating process closed bin, adopts a loading platform and a unloading platform to realize loading and unloading, adopts a carrier clamping and lifting mechanism to realize switching between the platforms in the coating process closed bin, adopts a carrier coating moving mechanism to ensure the realization of the coating process, adopts a membrane ring dipping and lifting mechanism to realize the replenishment of membrane ring membrane liquid, and through the joint cooperation between various mechanisms, it can ensure that the sensor probe coating process is carried out in an orderly manner; in addition, the various mechanisms work in a certain method and step sequence, which can ensure that the coating and balancing processes are carried out steadily, ensure the quality of the coating film and improve work efficiency.

[0005] The specific technical solution of the present invention is as follows: a sensor automatic coating device, comprising:

[0006] A closed chamber for the overcoating process, comprising a central overcoating position and a first balancing position and a second balancing position located on either side of the overcoating position, wherein the overcoating position is provided with an overcoating film ring and a film liquid tank;

[0007] The conveying platform includes a horizontally arranged flat-plate coating balance flow platform, a loading platform and a unloading platform;

[0008] A driving slide, comprising a coating balance driving slide, a loading slide and a unloading slide, wherein the coating balance driving slide, the loading slide and the unloading slide are respectively connected to the bottom of the coating balance flow platform, the loading platform and the unloading platform to drive their translational transportation;

[0012] Therefore, during the coating process, the sensor needs to be loaded and unloaded at the front and rear sides of the coating process closed warehouse, and needs to be transferred between the first balance warehouse, the coating warehouse and the second balance warehouse.

[0061] Therefore, during the coating process, the sensor needs to be loaded and unloaded at the front and rear sides of the coating process closed warehouse 1, and needs to be transferred between the first balance warehouse 12, the coating warehouse 11 and the second balance warehouse 13. The coating balance transfer platform 21 can be used to realize the circulation inside the coating process closed warehouse 1, the loading platform 22 and the unloading platform 23 can be used to realize loading and unloading, the carrier clamping and lifting mechanism 4 can be used to realize switching between the platforms in the coating process closed warehouse 1, the carrier coating moving mechanism 5 can ensure the realization of the coating process, and the membrane circle dipping and lifting mechanism 6 can realize the replenishment of the membrane circle membrane liquid; through the joint cooperation between the various mechanisms, the sensor probe coating process can be carried out in an orderly manner.

[0062] like Figure 1 、 Figure 2 The closed chamber 1 for overcoating process also includes a partition 14 located between the overcoating position 11, the first balancing position 12 and the second balancing position 13, and separating the three positions; the closed chamber 1 for overcoating process also includes a side panel 15 located on the side of the first balancing position 12 and the second balancing position 13, and a cavity switch door 151 is provided on the side panel 15.
