Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Combine the following Figures 1 to 3 A microelectrode automatic coating device provided in an embodiment of the utility model is described.

[0029] The present embodiment provides a microelectrode automatic coating device, comprising: a container cup 1, an electrode holder 2 and a position adjustment mechanism.

[0030] Among them, the container cup 1 is used to hold the membrane solution; the electrode clamp 2 is movably arranged above the container cup 1, and the electrode clamp 2 is used to fix the microelectrode; the position adjustment mechanism includes a first movable module 3 and a connecting arm 4, the first movable module 3 acts on the connecting arm 4, and is used to drive the connecting arm 4 to reciprocate along a first direction, and the end of the connecting arm 4 away from the first movable module 3 is connected to the electrode clamp 2, and the first direction is the height direction.

[0031] It can be seen from the above scheme that when the utility model is working, the microelectrode to be coated is fixed in the electrode holder 2, and then the connecting arm 4 is driven by the first movable module 3 to drive the electrode holder 2 to perform a lifting movement along the first direction above the container cup 1, so that the tip of the microelectrode is repeatedly immersed in the membrane solution along the first direction, thereby improving the repeatability of the microelectrode coating, and can improve the coating efficiency, realize the automated coating operation of the microelectrode, and ensure the coating quality of the microelectrode.

[0032] Furthermore, the electrode holder 2 is provided with a plurality of electrode mounting holes 21, so that the electrode holder 2 can fix a plurality of microelectrodes at one time, and can be selected according to the structure of the electrode holder 2. Compared with manual coating, the production efficiency is improved, and the coating quality of a plurality of microelectrodes is ensured, the coating thickness is consistent, and standardized production is realized.

[0033] In this embodiment, a controller 5 is included, and the controller 5 is electrically connected to the first movable module 3, and is used to control the movement of the electrode clamp 2; for example, the start and stop, operating speed, pause time, action frequency and other parameters of the first movable module 3 can be set by the controller 5 to achieve the control and adjustment of the microelectrode pulling rate, pause time, vibration distance and vibration number during the microelectrode coating process, and the film thickness of the microelectrode can be improved by adjusting the above-mentioned condition parameters.

[0034] It should be noted that the pulling rate is the movement rate of the microelectrode along the first direction in the membrane solution, the pause time is the immersion time of the microelectrode in the membrane solution, the vibration distance is the movement distance of the microelectrode in the membrane solution along the first direction, and the number of vibrations is the number of times the microelectrode is immersed in the membrane solution per unit time.

[0035] In this embodiment, the position adjustment mechanism also includes a second movable module 6 and a third movable module 7. The first movable module 3 is arranged on the second movable module 6, and the second movable module 6 can drive the first movable module 3 to move along the second direction; the third movable module 7 is arranged on the first movable module 3, and can move along the first direction under the drive of the first movable module 3; the connecting arm 4 is arranged on the third movable module 7, and the third movable module 7 can drive the connecting arm 4 to move along the third direction; the second movable module 6 and the third movable module 7 are both electrically connected to the controller 5.

[0036] In this arrangement, by adding a second movable module 6 and a third movable module 7 on the basis of the first movable module 3, the position adjustment of the connecting arm 4 and the electrode clamp 2 along the three directions of X, Y, and Z is realized, so that the microelectrode can move freely in three-dimensional space and be moved to a desired position to realize high-precision positioning of the microelectrode. For example, by fine-tuning the electrode clamp 2 in the X, Y, and Z directions, the microelectrode is placed directly above the membrane solution and is about 0.2 cm away from the surface of the membrane solution. By adopting the controller 5, the automatic adjustment of the movement direction, distance, and speed of the microelectrode can be realized, which reduces the requirements for the operator, reduces human errors, and makes the operation simpler and more reliable.

[0037] like Figure 3 As shown, in some specific embodiments, the first movable module 3 includes a first guide rail, a first driving assembly and a first movable seat, the first guide rail is arranged parallel to the height direction, the first movable seat is slidably connected to the first guide rail, and the first driving assembly acts on the first movable seat to drive the first movable seat to move along the height direction; the second movable module 6 includes a second guide rail, a second driving assembly and a second movable seat, the second guide rail is arranged along the second direction, the second movable seat is slidably connected to the second guide rail, the second driving assembly acts on the second movable seat to drive the second movable seat to reciprocate along the second direction, the second direction is perpendicular to the first direction, and the first guide rail is arranged on the second movable seat; the third movable module 7 includes a third guide rail, a third driving assembly and a third movable seat, the third guide rail is arranged on the first movable seat along the third direction, the third movable seat is slidably connected to the third guide rail, the third driving assembly acts on the third movable seat to drive the third movable seat to reciprocate along the third direction, and the connecting arm 4 is arranged on the third movable seat, and the third direction is respectively perpendicular to the second direction and the first direction. That is to say, the first driving module and the third driving module are driven to move together by the second moving seat moving along the second direction, the third driving module and the connecting arm 4 are driven to move together by the first moving seat moving along the first direction, and the connecting arm 4 is driven to move along the third direction by the third moving seat, thereby realizing the movement of the connecting arm 4 in three-dimensional space along the X, Y, and Z directions.

[0038] Optionally, the first drive component may include a servo motor, which is electrically connected to the controller 5 and is used to provide power to drive the first movable seat to move on the first guide rail. The transmission methods include but are not limited to gear rack transmission, screw transmission, belt pulley, sprocket chain and other linear drive methods. As long as it is used to convert the rotational motion of the servo motor into linear motion along the track, it can meet the requirements; of course, the first drive component may also be a linear power element such as a cylinder, a hydraulic cylinder or an electric cylinder, which is electrically connected to the controller 5.

[0039] Optionally, the first drive assembly, the second drive assembly and the third drive assembly have the same structure.

[0040] In some embodiments, a protective cover 8 is further included, which is sleeved on the container cup 1, and the protective cover 8 is provided with an adjustment hole 9 for the connecting arm 4 to pass through in the height direction. Figure 2 As shown, a protective cover 8 with a closed upper end and an open lower end is arranged outside the container cup 1 to protect the membrane solution in the container cup 1 and prevent the evaporation of the membrane solution; an adjustment hole 9 extending in the height direction is arranged on one side of the protective cover 8 to facilitate the connecting arm 4 to enter the protective cover 8 without causing interference to the electrode holder 2 when it moves in the height direction.

[0041] In this embodiment, a lifting platform 10 is further included. A positioning seat 11 is disposed on the lifting platform 10. The positioning seat 11 is provided with a fixing groove, and the container cup 1 is embedded in the fixing groove.

[0042] In this way, by setting up a lifting platform 10, the height of the container cup 1 can be adjusted to better cooperate with the position adjustment mechanism, which is beneficial to improving the coating quality of the microelectrode; by setting a positioning seat 11, the container cup 1 can be prevented from tilting or tipping over, which will not affect the microelectrode coating process. By embedding the container cup 1 in the fixing groove, the requirements of fixed installation are met, and it is convenient to take the container cup 1 out of the positioning seat 11 or put it into the positioning seat 11.

[0043] Preferably, the positioning seat 11 is provided with an observation port 12, which is connected to the fixing groove, and the internal situation of the fixing groove can be observed through the observation port 12; for example, the observation port 12 is opened on the positioning seat 11 along the height direction, and the observation port 12 is square. After fixing the container cup 1, it can be used to observe the movement of the microelectrode in the membrane solution.

[0044] In some embodiments, a lifting drive mechanism 13 is provided at the bottom of the lifting platform 10. The lifting drive mechanism 13 is electrically connected to the controller 5.

The driving part of the lifting drive mechanism 13 acts on the lifting platform 10 to drive the lifting platform 10 to perform lifting movements. The lifting drive mechanism 13 can be a common driving structure such as an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, a gear rack, etc., or it can be a scissors-type lift.

[0045] Furthermore, it also includes a shockproof platform 14. The bottom of the lifting drive mechanism 13 is connected to the shockproof platform 14. The shockproof platform 14 can use materials with vibration reduction function, such as rubber, springs or polymer materials, which can effectively absorb and disperse vibration energy and reduce the impact of vibration on the lifting platform 10 and the container cup 1; or, air springs, hydraulic shock absorbers, etc. can be set in the shockproof platform 14, which can use the compressibility of gas or the fluidity of liquid to absorb and disperse vibration energy.

[0046] With such arrangement, the vibration of the lifting drive mechanism 13 during operation can be absorbed by the anti-vibration platform 14 at the bottom, thereby ensuring the stability of the container cup 1 during the lifting process of the lifting platform 10 and preventing the membrane solution from spilling.

[0047] In some embodiments, a fixed seat 15 is also included. The fixed seat 15 is arranged on the shockproof platform 14, and the top of the fixed seat 15 is connected to the second movable module 6. The fixed seat 15 is arranged to provide stable support for the position adjustment mechanism, and the position adjustment mechanism is kept at a certain distance from the ground, thereby ensuring that the electrode holder 2 can move freely in three-dimensional space, and preventing objects, accumulated water, and debris on the ground from causing damage to the position adjustment mechanism. By arranging the fixed seat 15 on the shockproof platform 14, the vibration energy can be effectively absorbed during the process of the position adjustment mechanism driving the connecting arm 4 to move, thereby ensuring that the connecting arm 4 is more stable during operation.
