Description

Technical Field

[0001] This invention relates to the field of mechanical equipment technology, specifically to a spray pipe air blowing fixture and its air blowing control method. Background Technology

[0002] The spray nozzle plays a crucial role in the thermal management system of new energy vehicle battery packs. It is not only a medium for heat exchange but also a key component ensuring the safe operation of the battery system. The primary function of the spray nozzle is heat exchange with the battery. During operation, the battery generates a significant amount of heat. If this heat cannot be dissipated promptly, the battery temperature will rise, affecting its performance and lifespan. By maintaining close contact with the battery, the spray nozzle effectively absorbs and conducts the heat generated by the battery, rapidly dissipating it to the external environment, thus maintaining the battery within a suitable operating temperature range. In addition to its heat exchange function, the spray nozzle also needs high insulation performance. Since the battery pack contains high-voltage circuits, insufficient insulation between the spray nozzle and the battery could lead to electrical faults or short circuits, causing serious safety issues. Therefore, the surface of the spray nozzle is treated with a high-insulation material. This material effectively isolates current, preventing electrical faults. Furthermore, this material also possesses good heat resistance and corrosion resistance, enabling long-term stable operation in the harsh working environment of the battery pack.

[0003] Powder coating is a crucial step in the manufacturing process of spray-coated tubes. However, during powder coating, a layer of powder often adheres to the end of the tube. If this powder is not cleaned promptly, it will adversely affect subsequent coating processes. Specifically, residual powder alters the surface condition of the tube, leading to uneven film thickness distribution and reduced processing accuracy. Furthermore, residual powder may also affect the heat exchange efficiency and insulation performance between the tube and the battery, further impacting the overall performance of the battery pack. Summary of the Invention

[0004] The purpose of this invention is to provide a spray pipe blowing fixture and its blowing control method, which solves the problem that the powder adhering to the end of the spray pipe during the processing is inconvenient to clean in time, thereby affecting the film thickness of the pipe and reducing the processing accuracy of the pipe.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A spray nozzle air blowing fixture includes an air blowing fixture base. A freely retractable upper part of the air blowing fixture is inserted into the top of the base. A left and right air blowing pipe are respectively installed on both sides of the upper part. Compressed air pipes are connected to the ends of both the left and right air blowing pipes. Inclined cover plates are symmetrically arranged above the upper part of the air blowing fixture. Strip plates are connected to the cover plates via brackets. The strip plates are close to... Symmetrical upper guide supports are installed at the bottom of both ends. A lower guide support corresponding to the upper guide support is installed on the upper part of the air blowing fixture, and the upper guide support and the lower guide support are slidably inserted. Multiple crossbeams are installed between the lower side wall of the cover plate and the side wall of the strip plate. A detachable air blowing nozzle is installed at the bottom of the crossbeam. The left pipe and the right pipe of the air blowing fixture are respectively connected to hoses corresponding to the air blowing nozzles. A sealing docking mechanism is installed between the hoses and the air blowing nozzles.

[0007] As a further aspect of the present invention: the air blowing fixture base includes four rectangularly distributed square tubes, four upper connecting columns and four lower connecting columns, with the four upper connecting columns and the four lower connecting columns respectively circumferentially connected between two adjacent square tubes.

[0008] As a further embodiment of the present invention: the upper part of the air blowing fixture includes four inner tubes, two support plates and a support plate. The four inner tubes are respectively movably inserted into four square tubes. The left and right pipes of the air blowing fixture are respectively installed on the top of the two support plates. The top ends of the two inner tubes on the left and the two inner tubes on the right are respectively connected to the bottom of the two support plates. The support plate is welded between the four inner tubes and is used to install the lower guide support.

[0009] As a further aspect of the present invention: a first screw is threadedly installed on the side wall near the top of the lower guide support, one end of the first screw extending into the lower guide support and used to abut against the outer side wall of the upper guide support.

[0010] As a further aspect of the present invention: a second screw is threadedly installed on the side wall near the top of the square tube, one end of the second screw extending into the square tube and used to abut against the outer side wall of the inner tube.

[0011] As a further aspect of the present invention: the sealing docking mechanism includes a connector tube connected to the back of the air nozzle, a cap is fitted on the connector tube, an insert tube extending into the connector tube is rotatably installed at the center of the cap, a sealing ring is fitted on the outer wall of the insert tube and fits against the inner wall of the connector tube, and the end of the connector tube away from the sealing ring is connected to a flexible hose.

[0012] As a further aspect of the present invention: a threaded pin is installed at the bottom end of the air blowing nozzle, and a threaded groove is provided on the crossbeam for the threaded pin to be screwed into.

[0013] As a further embodiment of the present invention: the inner wall of the cap is provided with an internal thread, the outer wall of the connector tube is provided with an external thread, and the cap and the connector tube are threadedly connected.

[0014] A method for controlling the air blowing of a spray nozzle blowing fixture includes the following steps:

[0015] S1: Place the air blowing fixture base under the spraying process transmission device of the spraying pipe, and extend and adjust the upper part of the air blowing fixture above the air blowing fixture base to a suitable height so that the moving spraying pipe passes through the area between the two cover plates.

[0016] S2: Install multiple air nozzles at the bottom of multiple crossbeams respectively, and use a sealing docking mechanism to connect all hoses on the left and right pipes of the air blowing fixture to the multiple air nozzles respectively.

[0017] S3: Adjust the upper guide support so that it slides and extends along the lower guide support until the air nozzle corresponds to the end of the spray pipe;

[0018] S4: Connect the compressed air pipes at the ends of the left and right pipes of the air blowing fixture to the external air compressor in a sealed manner. Turn on the air compressor and blow air into the end of the spray pipe between the two cover plates to clean the powder that adheres to the end of the spray pipe during the processing.

[0019] The beneficial effects of this invention are:

[0020] 1. In this invention, the air-blowing fixture base is placed below the spraying process transmission device of the spraying pipe. Then, the upper part of the air-blowing fixture is telescopically adjusted above the air-blowing fixture base. After adjusting to a suitable height, the spraying pipe, which is easy to move, passes through the space between two cover plates. The two cover plates serve as a limit to minimize the shaking of the moving spraying pipe. The crossbeam facilitates the installation of the air-blowing nozzles. All air-blowing nozzles are connected to the left and right pipes of the air-blowing fixture, respectively. They are sealed and connected to an external air compressor through a compressed air pipe. When the air compressor is turned on, the air-blowing nozzles are directed at the spraying pipe passing between the two cover plates to blow air, cleaning the powder adhering to the end of the spraying pipe during processing. This air-blowing fixture can promptly clean the powder adhering to the spraying pipe during processing, avoiding affecting the film thickness of the pipe and improving the processing accuracy of the pipe.

[0021] 2. In this invention, the sealing and docking mechanism facilitates quick sealing and docking between the hose and the air blowing nozzle. The upper and lower guide supports facilitate fine-tuning of the height of the air blowing nozzle, making it easier for the air blowing nozzle to align with the end of the spray tube and improving the powder removal effect.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-6As shown, the present invention is a spray pipe blowing fixture, which includes a blowing fixture base 1. The blowing fixture base 1 includes four rectangular square tubes 101, four upper connecting columns 102, and four lower connecting columns 103. The four upper connecting columns 102 and four lower connecting columns 103 are circumferentially connected between two adjacent square tubes 101. A blowing fixture upper part 2 that can freely extend and retract vertically is inserted into the top of the blowing fixture base 1. An inclined cover plate 6 is symmetrically arranged above the blowing fixture upper part 2. The cover plate 6 is connected to a strip plate 7 through a bracket. Upper guide supports 8 are symmetrically installed near the bottom of the strip plate 7 at both ends. A lower guide support 9 corresponding to the upper guide support 8 is installed on the blowing fixture upper part 2, and the upper guide support 8 and the lower guide support 9 are slidably inserted. A first screw 13 is threadedly installed on the side wall near the top of the lower guide support 9. One end of the first screw 13 extends into the lower guide support 9 and is used to abut against the outer side wall of the upper guide support 8.

[0032] The upper part 2 of the air blowing fixture is equipped with a left air blowing fixture pipe 3 and a right air blowing fixture pipe 4 on both sides. The upper part 2 of the air blowing fixture includes four inner tubes 201, two support plates 202 and a support plate 203. The four inner tubes 201 are movably inserted into four square tubes 101. A second screw 14 is threaded on the side wall of the square tube 101 near the top. One end of the second screw 14 extends into the square tube 101 and is used to abut against the outer side wall of the inner tube 201. The left air blowing fixture pipe 3 and the right air blowing fixture pipe 4 are respectively installed on the top of the two support plates 202. The top ends of the two inner tubes 201 on the left and the two inner tubes 201 on the right are respectively connected to the bottom of the two support plates 202. The support plate 203 is welded between the four inner tubes 201 and is used to install the lower guide support 9.

[0033] Both the left pipe 3 and the right pipe 4 of the air blowing fixture are connected to compressed air pipes 5. In this embodiment, the compressed air pipes 5 are sealed and connected to an external air compressor. Multiple crossbeams 10 are installed between the lower side wall of the cover plate 6 and the side wall of the strip plate 7. A detachable air blowing nozzle 11 is installed at the bottom of the crossbeam 10. A threaded pin 19 is installed at the bottom of the air blowing nozzle 11. A threaded groove for the threaded pin 19 to be screwed into is opened on the crossbeam 10. The pipe walls of the left pipe 3 and the right pipe 4 of the air blowing fixture are respectively connected to hoses 12 corresponding to the air blowing nozzles 11. A sealing docking mechanism is installed between the hoses 12 and the air blowing nozzles 11.

[0034] The sealing and docking mechanism includes a connector tube 15 connected to the back of the air nozzle 11. A cap 16 is fitted on the connector tube 15. The inner wall of the cap 16 has an internal thread, and the outer wall of the connector tube 15 has an external thread. The cap 16 and the connector tube 15 are threaded together to facilitate docking. An insert tube 17 extending into the connector tube 15 is rotatably installed at the center of the cap 16. A sealing ring 18 that fits against the inner wall of the connector tube 15 is fitted on the outer wall of the insert tube 17 to ensure the sealing between the insert tube 17 and the connector tube 15. The end of the connector tube 15 away from the sealing ring 18 is connected to the hose 12.

[0035] A method for controlling the air blowing of a spray nozzle blowing fixture includes the following steps:

[0036] S1: Place the air blowing fixture base 1 below the spraying process transmission device of the spraying pipe, and extend and adjust the upper part 2 of the air blowing fixture above the air blowing fixture base 1 to a suitable height so that the moving spraying pipe passes through the area between the two cover plates 6.

[0037] S2: Install multiple air nozzles 11 at the bottom of multiple crossbeams 10 respectively, and use a sealing docking mechanism to connect the flexible hoses 12 on the left pipe 3 and right pipe 4 of the air blowing fixture to the multiple air nozzles 11 respectively.

[0038] S3: Adjust the upper guide support 8 so that it slides and extends along the lower guide support 9 until the air nozzle 11 corresponds to the end of the spray pipe;

[0039] S4: Connect the compressed air pipes 5 at the ends of the left pipe 3 and the right pipe 4 of the air blowing fixture to the external air compressor in a sealed manner. Turn on the air compressor and blow air into the end of the spray pipe between the two cover plates 6. This will clean the powder that adheres to the end of the spray pipe during the processing.

[0040] The working principle of this invention is as follows: First, the air blowing fixture base 1 is placed below the spraying process transmission device of the spraying pipe. Loosening the second screw 14 will push the inner tube 201 of the upper part 2 of the air blowing fixture to extend and retract along the square tube 101 of the air blowing fixture base 1. After adjusting to a suitable height, the second screw 14 is tightened, allowing the moving spraying pipe to pass through the area between the two cover plates 6. The two cover plates 6 are used to limit the movement of the spraying pipe and prevent it from shaking during movement. Then, the air blowing nozzle 11 connected with the threaded pin 19 is installed on the crossbeam 10. The insertion tube 17 at the end of the hose 12 is inserted into the connector tube 15 on the side of the air blowing nozzle 11. The sealing ring 18 ensures the seal between the insertion tube 17 and the connector tube 15. Rotate the cap 16 to thread it onto the connector tube 15 to complete the connection between the hose 12 and the air nozzle 11. Then, loosen the first screw 13 to push the upper guide support 8 to slide and extend along the lower guide support 9 so that the air nozzle 11 corresponds to the end of the spray tube. Tighten the first screw 13 to complete the adjustment. Finally, connect the compressed air pipes 5 at the ends of the left pipe 3 and the right pipe 4 of the air blowing fixture to the external air compressor in a sealed connection. Turn on the air compressor to blow air from the air nozzle 11 to the end of the coating tube to remove powder from the end of the spray tube.
