[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.

[0020] See also Figure 1-5 A new energy battery sealing test device in this embodiment includes an operating table 1 and a two-stage conveying table 2 installed on the operating table 1, the two-stage conveying table 2 is divided into a first section and a tail section, and a lower mold cavity 11 located between the first section and the tail section of the two-stage conveying table 2 and a forward push cylinder 10 connected to the lower mold cavity 11 are slidably connected on the surface of the operating table 1, and the ejection end of the forward push cylinder 10 is fixedly connected to the back of the lower mold cavity 11, and a four-station displacement device 25 located above the lower mold cavity 11 and the two-stage conveying table 2 is installed on the top of the operating table 1, and two support plates 14 and two guide rods 18 are fixed near the four-station displacement device 25. An upper plate 15 is fixed between the two support plates 14, and two push-down cylinders 16 are installed on the top of the upper plate 15. An upper mold cavity 17 is fixed between the ejection ends of the two push-down cylinders 16.

[0021] In the above structure, the battery transportation is completed by the first and tail sections of the two-stage conveyor platform, and then the battery is moved to the lower mold cavity in conjunction with the four-station displacement device. At the same time, the battery in the lower mold cavity can also be moved to the tail section of the two-stage conveyor platform and removed. Then the forward push cylinder is recovered to drive the lower mold cavity to be aligned below the upper mold cavity, and then the upper mold cavity and the lower mold cavity are driven to engage with each other through the downward push cylinder. After engaging, the sealing test of the battery is completed by guiding air to the inside, thereby realizing automated testing to improve efficiency and reduce errors.

[0022] like Figure 4-5 In the direction shown, a side thrust assembly is installed at the bottom of the upper plate 15, and two concave blocks 22 with inclined bottoms are fixed on both sides of the side thrust assembly. Four upper blocks 23 are fixed at the bottom of the upper plate 15, and a lower block 24 opposite to the upper block 23 and fitting with the bottom of the concave block 22 is fixed at the top of the upper mold cavity 17. When the upper mold cavity is engaged with the lower mold cavity, the side thrust assembly is operated at this time, driving the concave block to move between the upper block and the lower block, because the bottom of the concave block and the top of the lower block are both inclined, when the concave block moves, a downward thrust can be applied through the inclined part, thereby improving the firmness of the seal between the upper mold cavity and the lower mold cavity, and reducing the load of the push cylinder to increase the service life.

[0023] The top of the lower mold cavity 11 is provided with a plurality of adjustment holes 12 and two long plates 13 fixed by screws at the adjustment holes 12. The installation position of the long plates can be adjusted by the adjustment holes and screws, so the two long plates can be installed in a suitable position according to the size of the battery, and a suitable distance can be left to place the battery, so that the battery can be prevented from moving during the test to affect the test and cause errors.

[0024] The side thrust assembly includes two side thrust cylinders 19 installed at the bottom of the upper plate 15 and distributed front and back. An L-shaped block 20 is fixed to the ejection end of the side thrust cylinder 19. A movable plate 21 located below the upper plate 15 is fixed between the two L-shaped blocks 20. Two long holes are provided on the top of the movable plate 21. The ejection end of the push-down cylinder 16 passes through the long holes and is connected to the upper mold cavity 17. The side thrust cylinder provides power. Under the action of the side thrust cylinder, the movable plate can be driven to move back and forth through the L-shaped block. Under the action of the long holes, a moving space for the movable plate and the push-down cylinder is reserved. Therefore, the movable concave block can be moved to form a support between the upper block and the lower block in the space of the long holes.

[0025] like Figure 1-2 The back of the first section of the two-section conveyor 2 is equipped with two locking adjustment rods 8 and a limit block 7 fixed at the end of the first section. A guide plate 9 is fixed between the rod ends of the two locking adjustment rods 8. One end of the guide plate 9 is inclined. A positioning component is installed on the side of the first section of the two-section conveyor 2 opposite to the guide plate 9. The movement of the guide plate can be adjusted by the locking adjustment rod, so the positioning component can be used to guide and position the battery according to the size of the battery. At the same time, the limit block can prevent the battery from falling when it moves to the end, thereby playing the role of reservation waiting.

[0026] The positioning assembly includes a propulsion cylinder 3 installed at the first section of the two-section conveyor 2, and a clamping plate 4 opposite to the guide plate 9 is fixed to the ejection end of the propulsion cylinder 3. The clamping plate is driven to move by the propulsion cylinder, and in conjunction with the guide plate, the battery can be clamped and positioned.

[0027] In addition, the clamping plate 4 is provided with a plurality of positioning holes 5, and a stopper 6 is fixed inside the positioning hole 5 by screws. According to the size of the battery, the stopper is installed at a suitable position of the clamping plate through the positioning hole and the screw. When the above-mentioned propulsion cylinder drives the clamping plate to clamp and position the battery, the stopper can separate the two batteries by a distance to avoid collision during the transportation process.

[0028] The working principle of the above embodiment is:

[0029] The guide plate is adjusted to a suitable position through the locking adjustment rod, and the two long plates and the stopper are also adjusted. Then the first section of the two-stage conveyor table conveys the battery, and the guide plate guides the conveying until the battery is conveyed to the clamping block. The thrust cylinder drives the clamping block to be ejected. Under the thrust of the clamping block, the battery can be clamped and fixed through cooperation with the guide plate. At the same time, the two batteries can be kept at a certain distance through the stopper to avoid collision. Then the battery is transplanted into the lower mold cavity and limited between the two long plates through the four-station displacement device. After placement is completed, the forward push cylinder drives the lower mold cavity to pull back until the lower mold cavity is aligned with the upper mold cavity, and the downward push cylinder drives the upper mold cavity to buckle with the lower mold cavity. At the same time, the side push cylinder passes The L-shaped block drives the moving plate to move, and the moving plate can drive the concave block to move between the upper block and the lower block. Because the top of the lower block is inclined, and the bottom of the concave block is also inclined, when the concave block moves, it will exert a downward force, thereby improving the firmness of the sealing fit between the upper mold cavity and the lower mold cavity, and at the same time, it can also close the push-down cylinder, reduce the load of the push-down cylinder and increase its service life. When the test is completed, the above operation is reset until the lower mold cavity is located below the four-station displacement device, so that the tested battery can be transferred to the two-stage conveyor table through the four-station displacement device and removed, thereby realizing automated testing, improving test efficiency, and reducing test errors.
