Description

Technical Field

[0001] The utility model relates to the technical field of press-assembly equipment, in particular to a fuel cell stack press-assembly equipment. Background Art

[0002] A fuel cell is a chemical device that converts the chemical energy of a fuel directly into electrical energy. For a fuel cell, the output voltage of a single cell consisting of a set of electrodes and an electrolyte plate is relatively low during operation. In order to obtain high voltage and power, multiple cells are usually connected in series to form a battery stack. Adjacent cells are separated by bipolar plates, which serve to connect the upper and lower cells in series and provide a gas flow path.

[0003] Existing pressing equipment can adjust the height of the load-bearing base plate to adapt to the pressing operations of battery stacks of different specifications. For example, Chinese patent application number CN202120754046.8 discloses a fuel cell stack pressing equipment, including a mounting base plate, and the four ends of the bottom of the mounting base plate are provided with an adjustable support base, and the upper right end of the mounting base plate is provided with a transmission roller mechanism, and the two ends of the left side of the mounting base plate are provided with fixed side plates, and the two ends of the opposite side of the fixed side plate are provided with vertical shafts, and an upper pressing plate is movably installed on the vertical shaft, and the middle upper end of the upper pressing plate is connected to the fixed plate through a lifting shaft.

[0004] After the height of the load-bearing base plate of this equipment is adjusted, the limit seat of the corresponding height needs to be inserted into the installation groove of the fixed side plate to lift the load-bearing base plate. Then the load-bearing mechanism of the corresponding specifications needs to be replaced, which makes the operation of adjusting the height of the load-bearing base plate more cumbersome and affects the pressing efficiency. Utility Model Content

[0007] Technical Solution

[0008] To achieve the above objectives, the utility model is implemented through the following technical solutions: a fuel cell stack pressing device, including a base, shells are connected on both sides of the upper surface of the base, openings are penetrated through the two shells on the sides facing each other, a partition is longitudinally connected to the inside of the shell, teeth are provided on both sides of the inside of the shell, limit teeth are provided on both sides of the outer surface of the partition, gears are provided on both sides of the inside of the shell, the gears are meshed with the teeth, the length of the limit teeth is shorter than the length of the teeth, the limit teeth are located on the side of the partition surface away from the gear, and the gear is connected to a connecting rod on the side away from the limit teeth. The upper surface of the bottom plate is provided with a push rod, and the lower end of the push rod passes through the mounting plate and is connected to the pressing plate.

[0009] Preferably, a hollow shell is connected to the upper surface of the mounting plate.

[0010] Preferably, a controller body is installed on the outer surface of the shell on one side.

[0011] Preferably, both sides of the pressure plate are symmetrically connected with fixing blocks, and the two fixing blocks on the same side are fitted with the corresponding two sides of the partition.

[0014] Beneficial Effects

[0015] The utility model provides a fuel cell stack press-assembly device, which has the following beneficial effects:

[0016] Through the provided gears, connecting plates and other structures, the rotation of the threaded rod can drive the height of the base plate to rise or fall. After adjusting to the appropriate height, the dual-axis motor drives the screw to rotate, so that the connecting plate can push the gear, so that the gear engages with the teeth and the limit teeth at the same time, thereby supporting the base plate. Compared with the existing technology, only the dual-axis motor needs to drive the screw to rotate to fix the position of the gear, connecting rod and limit block, thereby supporting the base plate. The operation is relatively simple, and the height of the base plate can be adjusted conveniently. The base plate can be adjusted to a variety of heights, so that the equipment can be suitable for battery stacks of various specifications. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only 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.

[0024] See also Figure 1-5The utility model provides a technical solution: a fuel cell stack press-assembly device, including a base 1, shells 2 are connected to the upper surface of the base 1 on both sides, and openings are opened on the two shells 2 facing each other. The shells 2 are longitudinally connected with a partition 3, and teeth 4 are arranged on both sides of the shell 2. Limiting teeth 5 are arranged on both sides of the outer surface of the partition 3. Gears 6 are arranged on both sides of the shell 2. The gear 6 is meshed with the teeth 4. The length of the limiting teeth 5 is shorter than the length of the teeth 4. The limiting teeth 5 is located on the side of the surface of the partition 3 away from the gear 6. The gear 6 is connected to the side away from the limiting teeth 5 with a connecting rod 7. The end of the connecting rod 7 away from the gear 6 is rotatably connected to a connecting plate 8. The outer surface of the connecting rod 7 A limit block 9 is sleeved on the surface, and a base plate 10 is connected to the upper surface of the limit block 9. A dual-axis motor 11 is installed on the lower surface of the base plate 10. The output shafts on both sides of the dual-axis motor 11 are connected with screws, and the screws on both sides respectively penetrate the corresponding connecting plates 8 and are threadedly connected thereto. The upper surfaces of the two shells 2 are connected to the same mounting plate 12, and threaded rods 13 are longitudinally penetrated and rotatably connected on both sides of the upper surface of the mounting plate 12. The lower end of the threaded rod 13 penetrates the base plate 10, and the outer surface of the threaded rod 13 is threadedly connected to the base plate 10. A push rod 14 is longitudinally installed on the upper surface of the mounting plate 12, and the lower end of the push rod 14 penetrates the mounting plate 12 and is connected to a pressure plate 15, and the threaded rod 13 is driven by a motor.

[0025] During operation, the motor drives the threaded rod 13 to rotate, so that the height of the base plate 10 rises or falls. At the same time, the base plate 10 drives the gear 6 to move. Since the gear 6 is meshed with the teeth 4, the gear 6 will rotate. After the base plate 10 is adjusted to a suitable height, the dual-axis motor 11 drives the screws on both sides to rotate, so that the screws drive the connecting plate 8 to move, and the connecting plate 8 pushes the connecting rod 7 and the gear 6 to move, so that the gear 6 moves toward the limit tooth 5, and the connecting rod 7 will slide inside the limit block 9, and the gear 6 will mesh with the limit tooth 5 and the teeth 4 at the same time, so that the gear 6 cannot rotate. At this time, the position of the connecting rod 7 is fixed, so that the connecting rod 7 can support the base plate 10, and the push rod 14 pushes the pressing plate 15 downward to press the pressing plate 15 against the battery stack, thereby performing a press-fit operation.

[0026] See also Figure 1-5 The utility model provides a technical solution: a hollow shell 16 is connected to the upper surface of the mounting plate 12 , and a motor for driving the threaded rod 13 is located inside the shell 16 .

[0027] During operation, the outer shell 16 can make the device more neat as a whole, and the outer shell 16 can protect the motor inside.

[0028] See also Figure 1-5 The utility model provides a technical solution: a controller body 17 is installed on the outer surface of the housing 2 at one side, and the controller body 17 is electrically connected to the motor, the dual-axis motor 11, and the push rod 14.

[0029] During operation, the motor, the dual-axis motor 11 and other structures can be controlled through the setting of the controller body 17.

[0030] See also Figure 1-5 The utility model provides a technical solution: both sides of the pressing plate 15 are symmetrically connected with fixing blocks 18 , and the two fixing blocks 18 on the same side are fitted with the corresponding two sides of the partition 3 .

[0031] During operation, the fixing block 18 can limit the pressing plate 15, so that the moving process of the pressing plate 15 is more stable.

[0032] See also Figure 1-5 The utility model provides a technical solution: the gear 6 is made of stainless steel.

[0033] During operation, the gear 6 made of stainless steel has better hardness, which is conducive to the long-term use of the gear 6.

[0034] See also Figure 1-5 The utility model provides a technical solution: the height of the lower side of the connecting plate 8 is lower than the height of the lower side of the dual-axis motor 11.

[0035] During operation, when the bottom plate 10 moves downward, the connecting plate 8 will first contact the base 1 , thereby preventing the dual-axis motor 11 from colliding with the base 1 and causing damage to the dual-axis motor 11 .

[0036] In summary, the controller body 17 is used to control the motor so that the motor drives the threaded rod 13 to rotate, so that the height of the base plate 10 rises or falls, and at the same time, the base plate 10 drives the gear 6 to move. Since the gear 6 is meshed with the teeth 4, the gear 6 will rotate. After the base plate 10 is adjusted to a suitable height, the dual-axis motor 11 drives the screws on both sides to rotate, so that the screws drive the connecting plate 8 to move, and the connecting plate 8 pushes the connecting rod 7 and the gear 6 to move, so that the gear 6 moves toward the limit tooth 5, and the connecting rod 7 will slide inside the limit block 9, and the gear 6 will mesh with the limit tooth 5 and the teeth 4 at the same time, so that the gear 6 cannot rotate. At this time, the position of the connecting rod 7 is fixed, so that the connecting rod 7 can support the base plate 10, and the push rod 14 pushes the pressing plate 15 downward, so that the pressing plate 15 presses the battery stack, thereby performing a pressing operation. During the movement of the pressing plate 15, the fixed block 18 can limit the pressing plate 15, so that the movement process of the pressing plate 15 is more stable.
