Description

Technical Field

[0001] This utility model relates to the field of electrochemical etching technology, and in particular to an electrochemical etching tank for processing microstructures on the surface of biodegradable medical materials. Background Technology

[0002] Etching is a technique that removes part of the material using chemical reactions or physical impacts. Etching technology can be divided into two categories: wet etching and dry etching. Etching is also known as photochemical etching, which refers to removing the protective film of the area to be etched after exposure and development. During etching, the area comes into contact with a chemical solution to achieve a dissolving and corroding effect, forming an effect of concave or convex or hollow shapes. Electrochemical etching tanks for microstructure processing of biodegradable medical materials are a type of tank structure for etching medical materials.

[0003] Chinese Patent Publication No. CN203960050U discloses a glass substrate etching tank. The glass substrate etching tank includes a housing with sidewalls and a bottom. The bottom and sidewalls cooperate to form a receiving cavity with an opening at the top for holding etching solution. An inlet pipe is also laid within the receiving cavity, adjacent to the bottom of the housing. A first nozzle is provided on the side of the inlet pipe facing the opening. The etching solution enters the receiving cavity through the first nozzle of the inlet pipe, and the glass substrate enters the receiving cavity through the opening and is confined to the side of the inlet pipe facing the opening for etching.

[0004] Traditional electrochemical etching tanks lack necessary limiting and protective structures at their joints, making effective limiting and fixing difficult. This leads to joint displacement, directly threatening the safety of the etching tank during operation. At the same time, the electrochemical etching tank cannot perform heat exchange during operation, resulting in the inability to properly recover and utilize the heat generated during operation. This wastes energy and fails to realize the potential value of the heat. Utility Model Content

[0005] The main objective of this invention is to provide an electrochemical etching tank for microstructure processing of biodegradable medical materials. This effectively solves the problems mentioned in the background art, where traditional electrochemical etching tanks lack necessary limiting and protective structures at the joints, making effective limiting and fixing difficult and causing the joints to easily shift, directly threatening the safety of the etching tank during operation. At the same time, the electrochemical etching tank cannot achieve heat exchange function in the working state, so the heat generated during operation cannot be reasonably recovered and utilized, resulting in energy waste and failure to realize the potential value of heat.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] An electrochemical etching tank for microstructure processing of biodegradable medical materials includes an etching tank body and an inner frame. The inner frame is disposed inside the etching tank body. Support feet are fixedly connected to the bottom of the etching tank body near both sides. A handle is fixedly connected to the top of the inner frame. A guide frame is fixedly connected to the inner surface of the etching tank body. A lifting block adapted to the guide frame is fixedly connected to the outer surface of the inner frame. A discharge pipe is connected to the bottom of the etching tank body. A control valve is connected to the outer surface of the discharge pipe. An anode plate connector is fixedly connected to one end of the etching tank body near one side, and a cathode plate connector is fixedly connected to the other end of the etching tank body near the other side. A limit protection structure is connected to the end of the etching tank body.

[0008] As a further embodiment of this utility model, the limiting and protective structure includes a fixed base, a connecting frame, and a limiting plate. The fixed base is fixed to the end of the etching tank body, the connecting frame is located at the top of the fixed base, and the limiting plate is fixed to the bottom of the connecting frame. The limiting plate is also engaged on the outer surface of the anode plate connector and the cathode plate connector.

[0009] As a further embodiment of this utility model, a locking pin is fixedly connected to the outer surface of the connecting frame. The locking pin passes through the interior of the fixed base, and a locking head is sleeved on the outer surface of the locking pin.

[0010] As a further embodiment of this utility model, the connecting frame is fixedly connected to the fixed base by a locking pin and a locking head, and the fixed base has a slot inside that matches the locking pin.

[0011] As a further embodiment of this utility model, a heat-conducting plate is fixedly connected to the center of the bottom of the etching tank body, with a water inlet pipe inserted into one end of the heat-conducting plate and a water outlet pipe inserted into the other end of the heat-conducting plate.

[0012] As a further embodiment of this utility model, heat exchange tubes are distributed inside the heat-conducting plate, and the heat exchange tubes are connected to both the inlet pipe and the outlet pipe.

[0013] The beneficial effects of this utility model are as follows: by setting a limiting and protective structure, the joint of the electrochemical etching tank can be limited and protected, which can prevent the joint of the electrochemical etching tank from shifting and improve the safety of using the electrochemical etching tank.

[0014] By setting up a heat-conducting plate, water inlet pipe, water outlet pipe, and heat exchange pipe, heat exchange can be carried out during the operation of the electrochemical etching tank, and the heat generated by the operation of the electrochemical etching tank can be rationally utilized.
