[0024] See also Figures 1 to 5The utility model provides a technical solution: a portable membrane electrode frame bonding device, comprising: a base assembly, a pressure assembly 200, and a limit assembly 300. The base assembly comprises a base 100, a cover plate 110, a vertical plate 120, a limit rod 130, an electric push rod 111, and a pressure sensor 101. The vertical plates 120 are symmetrically installed on the left and right edges of the upper surface of the base 100. The cover plate 110 is installed on the side of the vertical plate 120 away from the base 100. The electric push rod 111 is installed on the upper surface of the cover plate 110. The upper surface of the base 100 is installed A limit rod 130 is installed, and the upper surface of the base 100 is recessed downward to form a limit groove, and a pressure sensor 101 is installed inside the limit groove. The limit assembly 300 is symmetrically installed on the left and right surfaces of the vertical plate 120, and a pressure assembly 200 is installed at the lower end of the electric push rod 111. The limit assembly 300 includes a threaded rod 310, a limit plate 330, an electromagnetic heating coil 340 and a rocker 320. The left and right ends of the threaded rod 310 are respectively installed with a rocker 320 and a limit plate 330, and the surface of the limit plate 330 is installed with an electromagnetic heating coil 340.
[0025] See also Figure 1 , Figure 2 , Figure 3 As the first embodiment of the utility model: the center position of the upper surface of the base 100 is depressed downward to form a limiting groove, and a pressure sensor 101 is installed at the bottom of the limiting groove. The pressure sensor 101 is a patch pressure sensor 101, and the pressure sensor 101 is electrically connected to the power supply and the computer device through a wire;
[0026] A strip-shaped through slot 260 is formed through the center of the surface of the left edge vertical plate 120, a threaded hole 122 is formed below the strip-shaped through slot 260, and threaded holes 122 are formed symmetrically on the surface of the right edge vertical plate 120 and the left vertical plate 120, and a limit assembly 300 is connected to the inner thread of the threaded hole 122;
[0027] The diameter of the threaded rod 310 is the same as the diameter of the threaded hole 122. A rubber pad is glued to the outer surface of the rocker 320 at the left end of the threaded rod 310. An electromagnetic heating coil 340 is installed on the side of the limit plate 330 at the right end of the threaded rod 310 away from the threaded rod 310. The electromagnetic heating coil 340 is electrically connected to the power supply through an electric wire. A 0.5 cm gap is set between the lower end of the limit plate 330 and the upper surface of the pressure sensor 101.
[0028] When in use, the user first prepares the membrane electrode frame body 400, and then clamps the membrane electrode body 430 with the upper frame 410 and the lower frame 420 inside the membrane electrode frame body 400, and then applies ion exchange adhesive to the abutment between the upper frame 410 and the lower frame 420, and then places the prepared membrane electrode frame body 400 at the center position inside the limiting groove so that it is on the upper side surface of the pressure sensor 101 (the model of the pressure sensor 101 is LPS25HBTR, and its working principle is the existing technology, which will not be repeated here), and then the user holds The rocker 320 is then rotated at the same time, so that a bearing is set at the connection between the threaded rod 310 and the limit plate 330. When the rocker 320 is rotated, the threaded rod 310 moves forward along the threaded hole 122, and then the two limit plates 330 are driven to move toward each other, and then the membrane electrode frame body 400 is abutted and clamped. When the limit plate 330 clamps the membrane electrode frame body 400, the electromagnetic heating coil 340 is also abutted against the membrane electrode frame body 400. When the two limit assemblies 300 are abutted and clamped, the user can start the electromagnetic heating coil The electromagnetic heating coil 340 is heated to about 100 degrees Celsius (because the bonding heating temperature of the ion exchange adhesive is usually between 70°C and 120°C), and then the user can start the electric push rod 111 to drive the pressure assembly 200 to descend and pressurize the membrane electrode frame body 400 inside the limit groove. Then the user can perform the above steps in reverse order to remove the laminated membrane electrode frame body 400. The electromagnetic heating coil 340 can control the temperature during the lamination process by heating the limit plate 330. By adjusting the electromagnetic heating coil The power and working time of the coil 340 (the temperature of the electromagnetic heating coil 340 is controlled at about 100 degrees Celsius) are controlled to achieve precise bonding temperature control, which helps to ensure proper flow and curing of the adhesive (ion exchange adhesive) to obtain a good bonding effect. The rocker 320, as part of the limit assembly 300, can manually adjust the position of the limit plate 330 by the user. This design allows the operator to make fine adjustments as needed to adapt to membrane electrodes and frames of different sizes and shapes, thereby improving the applicability and flexibility of the equipment and improving the ease of use of the device.
[0029] See also Figure 1 , Figure 2 , Figure 3 As the first embodiment of the utility model: two limiting rods 130 are symmetrically installed on the inner surfaces of the two vertical plates 120, the upper ends of the limiting rods 130 penetrate the pressure assembly 200 and are connected to the lower surface of the cover plate 110, and the outer surfaces of the limiting rods 130 are installed with buffer springs 131, the upper ends of the buffer springs 131 are connected to the lower surface of the pressure assembly 200, and the lower ends of the buffer springs 131 are connected to the upper surface of the base 100;
[0030] The pressure assembly 200 includes a pressure plate 210, a bearing block, a forward screw 230, a reverse screw 240, a pressure block 220 and a motor 260. The interior of the pressure plate 210 is designed as a receiving cavity. A bearing block is installed at the center of the interior of the pressure plate 210. The forward screw 230 and the reverse screw 240 are installed inside the pressure plate 210 through the bearing block. The forward screw 230 and the reverse screw 240 are connected to each other. The motor 260 is installed on the left surface of the pressure plate 210.
[0031] The motor 260 is arranged inside the strip-shaped through slot 260, and the output shaft of the motor 260 is connected to the left end of the forward screw 230 through a coupling. The outer surfaces of the forward screw 230 and the direction screw are symmetrically threadedly connected with a pressure block 220, and the height of the pressure block 220 is greater than the height of the limit plate 330. A rubber pad is glued to the lower surface of the pressure block 220, and the upper surface of the pressure plate 210 is connected to the telescopic rod of the electric push rod 111;
[0032] A membrane electrode frame body 400 is placed on the upper surface of the pressure sensor 101. The membrane electrode frame body 400 includes a membrane electrode body 430, an upper frame 410 and a lower frame 420. The membrane electrode body 430 is arranged between the upper frame 410 and the lower frame 420. An ion exchange adhesive is arranged at the abutment between the upper frame 410 and the lower frame 420.
[0033] When starting the pressure assembly 200, the user first starts the motor 260 to rotate the output shaft of the motor 260. When the output shaft of the motor 260 rotates forward, the forward screw 230 and the reverse screw 240 will rotate forward, thereby increasing the distance between the two pressure blocks 220 installed on the outer surface thereof. When the output shaft of the motor 260 is reversed, the forward screw 230 and the reverse screw 240 will rotate reversely, thereby decreasing the distance between the two pressure blocks 220 installed on the outer surface thereof. The user can adjust the distance between the pressure blocks 220 according to the width of the membrane electrode frame body 400 being clamped. When the adjustment is completed, the user can start the electric push rod 111. At this time, the telescopic rod of the electric push rod 111 is extended to drive the pressure plate 210 and the pressure block 220 to descend, so that one end of the rubber pad glued to the lower end of the pressure block 220 abuts against the upper frame 410 of the membrane electrode frame body 400 and then passes through. The pressure is applied by the pressure component 200, and the user can adjust the data transmitted to the computer device through the patch pressure sensor 101 on the lower surface of the membrane electrode frame body 400 (the specific pressure value should be adjusted according to the actual situation of the membrane electrode frame body 400, which is not listed here) to avoid damage to the membrane electrode frame body 400 due to excessive pressure, or poor bonding effect due to insufficient pressure. Therefore, the pressure component 200 can provide uniform pressure distribution to ensure that the membrane electrode frame body 400 is subjected to uniform pressure during the bonding process. This is very important for obtaining consistent bonding quality and helps to avoid uneven bonding strength or gaps. At the same time, by rotating the forward screw 230 and the reverse screw 240 through the motor 260, the spacing between the pressure blocks 220 can be achieved, which can be changed according to the size of the membrane electrode frame body 400 to meet the requirements of membrane electrodes and frames of different materials and sizes.
