In some embodiments, one side of the first groove 103 forms a slope structure, and the first groove 103 is used for clamping the positive electrode module 200 and guiding the positive electrode module 200 during clamping.
[0034] As shown in the drawings, Figure 4 The multifunctional film transfer box has a first direction X, and the third shell 130 is provided with a first guide boss 131 away from the side of the third shell 130 away from the negative electrode plate 120, and the first guide boss 131 extends along the first direction X. The multifunctional film transfer box is inserted into the film transfer instrument, and the first guide boss 131 completes the insertion of the multifunctional film transfer box.
[0035] In some embodiments, the first shell 110, the negative electrode plate 120 and the third shell 130 of the present application are sealed by the following method. The first shell 110 and the third shell 130 of the negative electrode module 100 are connected by screws, and the first shell 110 is provided with buckle mounting holes around, and the buckle is fixed on the first shell 110 by a pin. Further, the buckle installed on the negative electrode module 100 is clamped with the positive electrode module 200. Two circles of grooves are designed on the first shell 110 of the negative electrode module 100, and a sealing strip is embedded, and then the negative electrode plate 120 is fixed on the first shell 110 by screws, so as to press the sealing strip.
[0036] In some embodiments, the first mesh plate 104 is provided with a plurality of first protrusions 105, and the first protrusions 105 are used for supporting the negative electrode plate 120, and a layer of liquid storage cavity is formed between the first mesh plate 104 and the negative electrode plate 120.
[0037] In some embodiments, the first shell 110 is provided with a negative electrode circuit interface female head 106, which realizes the circuit connection of the negative electrode module 100.
[0038] As shown in the drawings, Figure 5 and Figure 6As shown, the positive electrode module 200 includes a second housing 210, positive electrode plates 220, and a fourth housing 240, and the positive electrode plates 220 are located between the second housing 210 and the fourth housing 240. The second housing 210 and the fourth housing 240 of the positive electrode module 200 are connected by screws, and two grooves are designed on the second housing 210 of the positive electrode module 200, and a sealing strip is embedded in the grooves. Then, the positive electrode plates 220 are fixed on the second housing 210 by screws, so that the sealing strip is compressed.
[0039] In some embodiments, a second mesh plate 205 is arranged in the second accommodating groove 202, and a plurality of second protrusions 206 are designed on the second mesh plate 205. The second protrusions 206 are used to abut against the positive electrode plates 220, so that a liquid storage cavity is formed between the second mesh plate 205 and the positive electrode plates 220.
[0040] As shown in Figure 5 The second housing 210 has a second side surface 201 facing the negative electrode module 100, and the second side surface 201 is provided with a second accommodating groove 202. The outer periphery of the second accommodating groove 202 is provided with a second groove 203, and the inner side of the second groove 203 is provided with a first protrusion 204. When the negative electrode module 100 is clamped with the positive electrode module 200, the first protrusion 204 is embedded in the first groove 103. In some specific embodiments, the second groove 203 is used to install a first sealing strip 207, and the first protrusion 204 arranged on the inner side of the second groove 203 corresponds to the first groove 103 arranged on the first housing 110. When the negative electrode module 100 is clamped, the negative electrode module 100 can compress the first sealing strip 207, and the first protrusion 204 can play a guiding role. After the positive electrode module and the negative electrode module are clamped, the sealing strips are embedded between the electrode plates on both sides and the corresponding lower housings, and the sealing rings are also embedded between the housings of each module. Further, the liquid inlet joint arranged on the positive electrode module 200 is also installed with a sealing ring, and during the liquid inlet and outlet process, the entire cavity becomes a sealed cavity. Through the improvement of the multifunctional membrane transfer box, the sealing performance of the inside of the membrane transfer box is improved, and the uniformity of the liquid in the accommodating cavity of the membrane transfer box is improved, and the membrane transfer performance of the membrane transfer box is improved.
[0041] The positive electrode module 200 includes a fourth housing 240, and the fourth housing 240 is provided with a second guide boss 241 away from the positive electrode plates 220, and the second guide boss 241 extends along the first direction X. The second guide boss 241 is used for guiding during the insertion of the multifunctional membrane transfer box into the membrane transfer instrument.
[0042] As shown in Figure 7As shown, the side surface of the second shell 210 is provided with a hole boss respectively from top to bottom, the liquid path male connector 107 of the application is screwed into the sealing ring, and the nut is locked through the hole. The positive electrode circuit interface female head 208 of the positive electrode module 200 is installed on the hole boss of the second shell 210. The circuit structure of the application can also be sleeved with a fluorine rubber tube to increase the sealing performance and safety performance.
[0043] The film transfer cassette and the multifunctional film transfer instrument module of the application have multiple purposes, such as realizing film transfer and dyeing. When the multifunctional film transfer instrument module in the embodiment of the application integrates multiple modules to realize multiple experiments at the same time, film transfer and dyeing can be realized at the same time in one instrument. In order to avoid the situation that the film transfer cassette is misassembled, the multifunctional film transfer cassette of the application is provided with an identification mechanism.
[0044] As shown in Figure 14 and Figure 15 In some embodiments, the multifunctional film transfer cassette of the application is also provided with an identification mechanism 300, a first identification site 301 is arranged on the negative electrode module 100, and a second identification site 302 is arranged on the positive electrode module 200. The first identification site 301 and the second identification site 302 of the film transfer cassette for film transfer are both protruding point structures. When the two protruding points resist the identification sites of the identification element 301 of the identification mechanism 300, the identification sites of the identification element 301 are displaced, and the identification mechanism 300 judges whether the positive electrode module and the negative electrode module for film transfer are correct. In some embodiments, the identification mechanism 300 includes two optical couplings as identification elements 301, and two elastic bolt mechanisms 303 corresponding to the two optical couplings are used to identify the insertion of the multifunctional film transfer cassette. In some embodiments, the identification element 301 is installed on the film transfer instrument, and the installation position corresponds to the position of the identification site after the multifunctional film transfer cassette is inserted into the film transfer instrument.
[0045] At the same time, the identification site of the film transfer cassette for dyeing is arranged as a concave point. When the multifunctional film transfer cassette is misassembled, one of the two optical couplings does not displace the bolt mechanism 303, and the identification mechanism 300 can complete the misjudgment.
[0046] As shown in Figures 8-13 The second screen plate 205 is provided with a glue isolation ring 230, and at least a notch 231 is arranged on the outer circle of the glue isolation ring 230. The glue isolation ring 230 of the application can solve the size difference of the glue used in the experiment, mid glue or mini glue. Different glue isolation rings 230 can be embedded on the second screen plate 205 to limit the placement position of the glue, reduce the ionization of the excess liquid space, and make the current of the same size of glue have no large difference during each film transfer.
[0047] In some embodiments, the gaps 231 distributed on the glue barrier ring 230 are located on the upper and lower side edges of the glue barrier ring 230, and are used for the communication of the liquid between the internal cavities of the multifunctional membrane transfer box, so as to avoid the uneven internal pressure of the liquid or the local accumulation of the liquid, and affect the membrane transfer or dyeing effect.
[0048] In some embodiments, the upper and lower side edges of the glue barrier ring 230 are provided with first edges 232, the thickness of the first edges is smaller than the thickness of the main body of the glue barrier ring 230, and the thinner first edges 232 distributed on the upper and lower sides of the glue barrier ring 230 facilitate the flow of the liquid, and avoid the accumulation of the liquid at the edges of the glue barrier ring 230, which affects the membrane transfer or dyeing effect.
[0049] As shown in Figure 6 The multifunctional membrane transfer box in the embodiments of the present application includes a temperature sensor 209, which can solve the problem that the temperature in the membrane transfer process of the membrane transfer box is not monitored in the prior art. If the temperature is too high, the glue may be burned. The temperature sensor of the present application monitors the temperature in the membrane transfer process of the membrane transfer box. If the temperature is too high, the glue may be burned, and the experimental parameters can be adjusted in time.
