Description

Technical Field

[0001] The present application relates to a water-cooled plate inspection device, in particular to a water-cooled plate helium inspection tool and an automatic helium inspection machine. Background Art

[0002] The water-cooling plate is a heavy component of the battery pack's liquid cooling system. After assembly, the plate requires a leak-tightness test. Conventional helium testing machines for water-cooling plates typically position the plate horizontally on a positioning mechanism and clamp it with a pressure plate. This horizontal positioning of the helium testing machine can easily cause particulate matter to pass through the pressure plate and damage the plate. Summary of the Invention

[0003] In view of this, the present application provides a water-cooled plate helium inspection tool and an automatic helium inspection machine, which adopt a vertical positioning structure to improve the situation where particulate matter damages the water-cooled plate.

[0004] In order to achieve the above objectives, this application is implemented through the following technical solutions:

[0005] The cam assembly is fixedly mounted on the bottom plate and is used to press the bottom plate to the left and right of the water-cooled plate, and the cam assembly is fixedly mounted on the bottom plate and is located on the left and right sides of the cam assembly.

[0006] The aforementioned helium inspection tool for a water-cooled plate employs a positioning plate to position the plate vertically. A fixed pressure plate assembly and a movable pressure plate assembly clamp the plate from both sides, preventing particles from falling onto the plate and crushing the product. Furthermore, a locking mechanism mechanically locks the movable pressure plate assembly to prevent the plate from expanding and pushing open during helium filling, causing deformation.

[0007] In some embodiments, two or more latches are fixedly mounted on a connecting plate, and the piston rod of the second cylinder is fixedly connected to the connecting plate. The base plate is provided with a first guide groove for guiding the insert block left and right, and limit plates are fixedly provided on the front and rear sides of the insert block to prevent the insert block from moving upward. A seat block is fixedly provided in the first guide groove, and a first screw is rotatably connected to the seat block. The first screw is threadedly connected to the insert block, and rotation of the first screw can drive the insert block to move left and right within the first guide groove. A circular top block is also provided in the first guide groove, located between the seat block and the insert block. The mounting hole of the circular top block is eccentrically arranged and fixed to the first guide groove by a screw. Rotating the first screw can adjust the position of the insert block in the left and right directions, and the rotation angle of the circular top block can be adjusted to support the insert block. This mounting structure facilitates adjustment of the insert block.

[0008] In some embodiments, the movable pressure plate assembly is slidably connected relative to the base plate via a slide rail and slider mechanism.

[0009] In some embodiments, the sealing mechanism includes two sealing assemblies arranged opposite to each other in the left-right direction, the sealing assembly including a bottom block fixedly mounted on the bottom plate, a first guide rod fixedly mounted on the bottom block and extending vertically, a mounting block slidably mounted on the first guide rod, a second screw rod threadedly connected to the mounting block and rotatably connected relative to the bottom block, a second guide rod fixedly mounted on the mounting block and extending in the left-right direction, a movable block slidably mounted on the second guide rod, a third cylinder fixedly mounted on the mounting block for pushing the movable block to move left and right, and a sealing cup fixedly mounted on the movable plate for sealing the tube head of the water-cooled plate collector, the sealing cup being provided with a helium filling port connected to a helium filling machine. The sealing cup can seal the tube head when the tube head is inserted. The height position of the mounting block can be adjusted by rotating the second screw rod, so that the sealing cup is easily aligned with the tube head during the debugging process.

[0010] In some embodiments, the movable pressure plate assembly and the fixed pressure plate assembly both include a base plate, a bracket fixedly mounted on the base plate, an inner plate fixedly mounted on the bracket, and an outer plate fixedly mounted on the inner plate, the inner plate including a middle plate and replaceable side plates located at the front and rear ends of the middle plate, the bracket including a side frame for fixedly mounting the replaceable side plates, the base plate is provided with a plurality of first adjustment holes spaced apart front to back, and a second guide groove extending along the front and rear directions for guiding the side frame front to back, the side frame is fixedly connected to the corresponding first adjustment holes by screws; the bottom plate is also provided with a plurality of second adjustment holes spaced apart front to back, and the bottom block of the sealing assembly is fixedly connected to the corresponding second adjustment holes by screws.

[0011] When the water-cooled plate helium inspection tooling needs to adapt to water-cooled plates of different lengths, it is necessary to remove the outer plate and the current replaceable side plate, adjust the front and rear positions of the side frames, and then replace the replaceable side plates of the corresponding length and install the new outer plate. In addition, by adjusting the front and rear positions of the sealing assembly and then replacing the new sealing cup and the height position of the sealing cup, the water-cooled plate helium inspection tooling has wider applicability and greater flexibility.

[0012] The present application also provides an automatic helium inspection machine, which has the above-mentioned water-cooled plate helium inspection tooling, and is characterized in that it also includes a sealed box that can be automatically opened and closed, a vacuuming device for vacuuming the sealed box, and a helium detector for detecting whether there is helium leaking from the water-cooled plate into the sealed box, and the bottom plate is fixedly installed in the sealed box.

[0013] It can be seen from the above technical solution that this application has at least the following advantages and positive effects:

[0014] This application discloses a helium inspection tool for a water-cooled plate. This tool utilizes a positioning plate to position the water-cooled plate vertically. A fixed pressure plate assembly and a movable pressure plate assembly clamp the water-cooled plate from both sides. This prevents particles from falling onto the vertically positioned water-cooled plate, thereby minimizing the risk of crushing the product. Furthermore, a locking mechanism mechanically locks the movable pressure plate assembly to prevent the water-cooled plate from expanding and pushing open the movable pressure plate assembly during helium filling, potentially causing deformation of the water-cooled plate.

During helium inspection, pipe heads 93 at both ends of the current collector 92 need to be sealed.

[0025] See Figures 1 to 7 The automatic helium detection machine for the water-cooled plate 9 includes a water-cooled plate 9 helium detection tool, a sealing box that can be automatically opened and closed, a vacuuming device for vacuuming the sealing box, and a helium detector for detecting whether there is helium leaking from the water-cooled plate 9 into the sealing box.

[0026] The helium inspection tooling for the water-cooled plate 9 includes a base plate 1 fixedly mounted in a sealed box, a positioning plate 2 fixedly mounted on the base plate 1 for vertically placing the water-cooled plate 9, a fixed pressure plate assembly 3 fixedly mounted on the base plate 1 and located on the left and right sides of the positioning plate 2, a movable pressure plate assembly 4 slidably connected to the base plate 1 along the left and right directions for pressing the plate body 91 of the water-cooled plate 9, a first cylinder 5 for driving the movable pressure plate assembly 4 to move left and right, a locking mechanism 6 for locking the movable pressure plate assembly 4 in a pressed position, and fixedly mounted on the front and rear sides of the positioning plate 2 for sealing both ends of the water-cooled plate 9. The sealing mechanism of the current collector 92 and the helium inflator for filling helium into the water-cooled plate 9 through the sealing mechanism; when the movable pressure plate assembly 4 moves closer to the fixed pressure plate assembly 3, the movable pressure plate assembly 4 clamps the plate body 91 of the water-cooled plate 9 on the fixed pressure plate assembly 3, and the locking mechanism 6 includes a latch 61, a second cylinder 62 installed on the movable pressure plate assembly 4 for driving the latch 61 to move vertically up and down, and an insert block 63 fixedly installed on the base plate 1 and with a pin hole 631.

[0027] This helium inspection machine uses a positioning plate 2 to position the water-cooled plate 9 vertically. A fixed pressure plate assembly 3 and a movable pressure plate assembly 4 clamp the water-cooled plate 9 from both sides. This prevents particles from falling onto the vertically positioned water-cooled plate 9, thereby minimizing the risk of crushing the product. Furthermore, a locking mechanism 6 mechanically locks the movable pressure plate assembly 4, preventing the water-cooled plate 9 from expanding and pushing against the movable pressure plate assembly 4 during helium filling, potentially causing deformation.

The first screw 67 is threadedly connected to the insert block 63, and rotation of the first screw 67 drives the insert block 63 to move left and right within the first guide slot 11. A circular top block 68 is also positioned between the seat block 66 and the insert block 63 within the first guide slot 11. The mounting hole of the circular top block 68 is eccentrically positioned and is fixed to the first guide slot 11 by screws. Rotating the first screw 67 adjusts the position of the insert block 63 left and right, and the rotation angle of the circular top block 68 is adjusted to support the insert block 63. This mounting structure facilitates adjustment of the insert block 63.

[0029] The movable pressing plate assembly 4 is slidably connected relative to the base plate 1 via a slide rail and slider mechanism 8 .

The sealing assemblies 7 include a bottom block 71 fixedly mounted on the base plate 1, a first guide rod 72 fixedly mounted on the bottom block 71 and extending vertically, a mounting block 73 slidably mounted on the first guide rod 72, a second screw rod 74 threadedly connected to the mounting block 73 and rotatably connected relative to the bottom block 71, a second guide rod 75 fixedly mounted on the mounting block 73 and extending in the left-right direction, a movable block 76 slidably mounted on the second guide rod 75, a third cylinder 77 fixedly mounted on the mounting block 73 for pushing the movable block 76 left and right, and a sealing cup 78 fixedly mounted on the movable plate for sealing the tube head 93 of the fluid collector 92 of the water-cooling plate 9. The sealing cup 78 is provided with a helium filling port connected to the helium filling machine. The sealing cup 78 can seal the tube head 93 when inserted into the tube head 93. The height position of the mounting block 73 can be adjusted by rotating the second screw rod 74, facilitating alignment of the sealing cup 78 with the tube head 93 during commissioning.

The bracket 42 includes a side frame 421 for fixing the replaceable side plate 432. The base plate 41 is provided with a plurality of first adjustment holes 411 spaced apart in front and back, and a second guide groove 412 extending along the front and rear directions for guiding the side frame 421 in the front and rear directions.

[0034] The sealed box is opened, and the water-cooled plate 9 is positioned on the positioning plate 2. The sealed box is then sealed. Driven by the first cylinder 5, the movable pressure plate assembly 4 compresses the plate body 91 of the water-cooled plate 9. The second cylinder 62 drives the latch 61 downward and inserts it into the pin hole 631 of the insert block 63, forming a locking structure. The sealing assemblies 7 at both ends operate independently, with the sealing cup 78 driven by the third cylinder 77 to insert into the pipe head 93 of the water-cooled plate 9, sealing the water-cooled plate 9. The vacuum equipment evacuates the sealed box, and the helium filling machine fills the water-cooled plate 9 with helium through the sealing cup 78. The helium detector detects any helium leaks to confirm the sealing of the water-cooled plate 9.
