[0032] In the water electrolysis hydrogen production system, the bipolar plate plays a vital role, and the sealing performance of the bipolar plate will directly affect the efficiency and safety of the entire system. In the related technology, the sealing of the bipolar plate is usually achieved by using rubber strips, which need to have good chemical resistance, temperature resistance, elasticity and durability to adapt to the harsh environment during the electrolysis process. The more accurate the attachment between the rubber strip and the groove of the bipolar plate, the better the sealing effect of the rubber strip on the bipolar plate. In view of this, how to achieve the alignment of the rubber strip in the groove of the bipolar plate is a problem that needs to be solved urgently.

[0033] In view of this, the present application provides an electrolytic cell bipolar plate gluing auxiliary positioning device and a gluing device. On the basis of realizing the primary positioning between the bipolar plate jig and the rubber strip jig by a driving component, the secondary positioning between the bipolar plate jig and the rubber strip jig is realized by positioning pins, thereby improving the positioning accuracy and ensuring the accurate attachment of the rubber strip in the groove of the bipolar plate.

[0034] The present application will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0035] like Figure 1 and Figure 2 As shown, the embodiment of the present application provides an electrolytic cell bipolar plate gluing auxiliary positioning device, which includes a bipolar plate fixture 12, a rubber strip fixture 11 and a driving component 13:

[0036] The bipolar plate fixture 12 has a fixing device for fixing the bipolar plate 2;

[0037] The rubber strip fixture 11 has a rubber strip groove 113 for fixing the rubber strip;

[0038] The driving assembly 13 cooperates with the bipolar plate jig 12 to realize a primary positioning between the bipolar plate jig 12 and the rubber strip jig 11, and realizes the flipping of the bipolar plate jig 12 after the primary positioning;

[0039] The bipolar plate jig 12 has a first positioning hole 121 , and the rubber strip jig 11 is fixed with a positioning pin. The first positioning hole 121 is used to achieve secondary positioning between the bipolar plate jig 12 and the rubber strip jig 11 through the positioning pin after the driving assembly 13 flips the bipolar plate jig 12 .

[0040] Specifically, Figure 1 As shown, Figure 1 (a) in the figure shows the structure diagram of a rubber strip fixture. Figure 1 (b) in the figure shows a structural diagram of a bipolar plate jig, wherein the bipolar plate jig 12 has a fixing device for fixing the bipolar plate 2, that is, the bipolar plate 2 can be placed on the bipolar plate jig 12, and the rubber strip jig 11 has a rubber strip groove 113 for fixing the rubber strip, that is, the rubber strip can be placed in the rubber strip groove 113 of the rubber strip jig 11, and the relative position accuracy between the rubber strip and the rubber strip jig 11 can be achieved through the rubber strip groove 113.

[0041] like Figure 2As shown, the driving component 13 cooperates with the bipolar plate jig 12 to achieve a one-time positioning between the bipolar plate jig 12 and the rubber strip jig 11, that is, the driving component 13 can be used to ensure the initial positioning between the bipolar plate jig 12 and the rubber strip jig 11. After the one-time positioning, the driving component 13 can realize the flipping of the bipolar plate jig 12, so that the bipolar plate fixed on the bipolar plate jig can face the rubber strip jig 11. In actual applications, the driving component 13 can be a servo motor. By inputting the corresponding position coordinates into the servo motor, the bipolar plate jig 12 can be controlled to move to the target position to achieve a one-time positioning between the bipolar plate jig 12 and the rubber strip jig 11. At the same time, the servo motor can also control the flipping of the bipolar plate jig 12.

[0042] In the present application, in order to ensure the positioning accuracy between the bipolar plate jig 12 and the rubber strip jig 11, the bipolar plate jig 12 has a first positioning hole 121, and correspondingly, a positioning pin is fixed on the rubber strip jig 11. In actual applications, the positioning pin can be fixed to the rubber strip jig 11 by welding, bonding, etc., so that after the driving component 13 flips the bipolar plate jig 12, the positioning pin can be aligned with the first positioning hole 121 to achieve secondary positioning between the bipolar plate jig 12 and the rubber strip jig 11, thereby improving the positioning accuracy between the bipolar plate jig 12 and the rubber strip jig 11 through two positioning.

[0043] It should be noted that in the present application, since the positioning pin is fixed in the second positioning hole 111 of the rubber strip jig 11, in the secondary positioning, the positioning pin only needs to be positioned with the first positioning hole 121 of the bipolar plate jig 12, thereby ensuring the matching accuracy between the bipolar plate jig 12 and the rubber strip jig 11.

[0044] In addition, in the present application, the positioning pin mainly plays the role of secondary positioning, and the primary positioning is achieved by the driving component 13, that is, the positioning pin is mainly used for deviation correction during the gluing process. Only when the accuracy of the preceding action is up to standard, such as ensuring that the accuracy of the primary positioning of the driving component 13 is up to standard, can the positioning pin play the role of secondary positioning in the subsequent steps.

[0045] In a possible implementation, the rubber strip jig 11 has a second positioning hole 111 corresponding to the first positioning hole 121 , and a positioning pin is placed in the second positioning hole 111 .

[0046] Specifically, the rubber strip jig 11 has a second positioning hole 111 corresponding to the first positioning hole 121 , and a positioning pin is placed in the second positioning hole 111 , that is, the positioning pin can be fixed at the corresponding position of the rubber strip jig 11 through the second positioning hole 111 .

[0047] In a possible implementation, in order to ensure positioning accuracy and avoid over-positioning, the number of the first positioning holes 121 and the second positioning holes 111 should not be too large. Figure 1 As shown, the bipolar plate jig 12 may have two first positioning holes 121 , the rubber strip jig 11 may have two second positioning holes 111 , and two positioning pins may be fixed in the two second positioning holes 111 , respectively.

[0048] In a possible implementation, in order to ensure positioning accuracy, Figure 1 As shown, the line between the two first positioning holes 121 can be parallel to the long side of the bipolar plate fixture 12 , and the line between the two second positioning holes 111 can be parallel to the long side of the rubber strip fixture 11 .

[0049] In one possible implementation, when two positioning pins are included, the two positioning pins may include a cylindrical pin 1121 and a pin side pin 1122. When the pin side pin 1122 is fixed to the second positioning hole 111, the long side of the pin side pin 1122 may be perpendicular to the line between the two second positioning holes 111, thereby ensuring the positioning effect.

[0050] In a possible implementation, on the basis of the first positioning hole 121 on the bipolar plate jig 12, the bipolar plate 2 may have a third positioning hole corresponding to the first positioning hole 121, and the first positioning hole 121 and the third positioning hole may be used to achieve positioning between the bipolar plate 2 and the bipolar plate jig 12 through a movable pin. In other words, the relative position accuracy between the bipolar plate and the bipolar plate jig may be ensured through the first positioning hole 121 and the third positioning hole, and the implementation method may be to ensure that the third positioning hole on the bipolar plate 2 is aligned with the first positioning hole 121 on the bipolar plate jig 12 when the bipolar plate is being fed, and then the positioning accuracy between the bipolar plate 2 and the bipolar plate jig 12 may be ensured through a movable pin.

[0051] It should be noted that in order to facilitate the positioning pin to pass through the first positioning hole 121 and the second positioning hole 111 to achieve secondary positioning between the bipolar plate fixture 12 and the rubber strip fixture 11, the movable pin will be removed after completing the positioning between the bipolar plate 2 and the bipolar plate fixture 12. At this time, in order to facilitate the removal of the movable pin, the movable pin will be longer than the positioning pin.

[0052] In one possible implementation, the fixing device may include a suction cup arranged on the bipolar plate jig 12, and the suction cup is used to fix the bipolar plate 2 on the bipolar plate jig 12 after the bipolar plate 2 and the bipolar plate jig 12 are positioned, that is, after the positioning between the bipolar plate 2 and the bipolar plate jig 12 is achieved through the first positioning hole 121 and the third positioning hole, the suction cup on the bipolar plate jig 12 can be opened to ensure that the relative position between the bipolar plate 2 and the bipolar plate jig 12 is fixed.

[0053] In a possible implementation, the fixing device may further include four pressing plates respectively arranged at the four corners of the bipolar plate fixture 12 , and the four pressing plates are used to auxiliary fix the bipolar plate 2 on the bipolar plate fixture 12 , that is, the four pressing plates can play an auxiliary fixing role.

[0054] In one possible implementation, Figure 2 As shown, the driving component 13 can be used to fix the bipolar plate jig 12 above the rubber strip jig 11, that is, the driving component 13 can keep the bipolar plate jig 12 above the rubber strip jig 11. As long as the driving component 13 does not move, the relative stillness of the bipolar plate jig 12 and the rubber strip jig 11 can be ensured.

[0055] In a possible implementation, the rubber strip jig 11 may include a floating plate arranged below and a plurality of assembly sub-plates arranged above the floating plate. The sub-grooves corresponding to the plurality of assembly sub-plates are combined to form a rubber strip groove 113. The rubber strip may be fixedly placed in the rubber strip groove 113. The floating plate is used to drive the rubber strip fixedly placed in the rubber strip groove 113 after secondary positioning to achieve the bonding between the rubber strip and the bipolar plate 2. Figure 3 As shown, the floating plate drives the rubber strip to move upward to achieve the bonding between the rubber strip and the bipolar plate 2 .

[0056] The embodiment of the present application also provides a gluing device, which includes the electrolytic cell bipolar plate gluing auxiliary positioning device of the aforementioned embodiment.

[0057] It can be seen that the present application provides an auxiliary positioning device and glue sticking equipment for the bipolar plate of an electrolytic cell, and the auxiliary positioning device for the bipolar plate of an electrolytic cell includes a bipolar plate jig, a rubber strip jig and a driving assembly: the bipolar plate jig has a fixing device for fixing the bipolar plate; the rubber strip jig has a rubber strip groove for fixing the rubber strip; the driving assembly cooperates with the bipolar plate jig to realize the primary positioning between the bipolar plate jig and the rubber strip jig, and realize the flipping of the bipolar plate jig after the primary positioning; the bipolar plate jig has a first positioning hole, the rubber strip jig has a second positioning hole corresponding to the first positioning hole, and a positioning pin is fixed in the second positioning hole, and the first positioning hole is used to realize the secondary positioning between the bipolar plate jig and the rubber strip jig through the positioning pin after the driving assembly flips the bipolar plate jig. On the basis of realizing the primary positioning between the bipolar plate jig and the rubber strip jig by the driving assembly, the secondary positioning between the bipolar plate jig and the rubber strip jig is realized by the positioning pin, which improves the positioning accuracy and ensures the accurate attachment of the rubber strip in the groove of the bipolar plate.
