Description

Technical Field

[0001] This application relates to the technical field of copper-aluminum finned condenser production, and more particularly to a drying device for detecting air leakage in a copper-aluminum finned condenser for a vehicle refrigerator. Background Technology

[0002] Currently, after the copper-aluminum finned condenser is manufactured, it needs to be tested for leaks. In existing technology, quick-connect fittings are usually installed at both ends of the copper tube, and then high-pressure air is injected into the copper tube. The tube is then placed in a water tank to see if any bubbles are generated. After the test is completed, it needs to be dried.

[0003] In existing technologies, copper-aluminum finned condensers are typically placed flat on a chain conveyor belt and dried from the top. However, this method results in poor drying efficiency. The bottom of the copper-aluminum finned condenser has a large contact area with the chain conveyor belt, and the airflow is blocked by the chain conveyor belt, leading to poor convection and thus affecting the drying effect.

[0004] Therefore, in order to improve the drying effect of copper-aluminum finned condensers, it is urgent to develop a drying device with good drying effect. Utility Model Content

[0005] The purpose of this application is to provide a drying device for detecting air leakage in a copper-aluminum finned condenser of a vehicle refrigerator, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a drying device for detecting leaks in copper-aluminum finned condensers of vehicle refrigerators, employing the following technical solution: A drying device for detecting leaks in copper-aluminum finned condensers of vehicle refrigerators includes a frame and a drying mechanism and a feeding mechanism mounted on the frame. The feeding mechanism is located next to the drying mechanism. The drying mechanism includes a conveyor line and a drying assembly. The conveyor line is mounted on the frame, and the drying assembly is located on top of the conveyor line. The conveyor line includes a geared drive motor, a drive shaft, a driven shaft, a plate chain, and a placement platform. The drive shaft and the driven shaft are rotatably connected to the frame, and the plate chain is sleeved on the drive shaft and the driven shaft. The geared drive motor is fixed to the frame and is used to drive the drive shaft to rotate. Multiple placement platforms are evenly mounted on the plate chain. The drying assembly includes a drying chamber with openings on both sides. The drying chamber is located at the top of the conveyor line. Two air knives are respectively provided on both sides of the inner wall of the drying chamber. The orthographic projections of the two air knives are parallel and do not intersect. An exhaust pipe is connected to the drying chamber at the position corresponding to the air knives.

[0007] Preferably, the unloading mechanism includes a mounting frame, a servo linear guide slide, a lifting cylinder, and a clamping assembly. The mounting frame is fixed on the machine frame, the servo linear guide slide is fixed on the mounting frame, the lifting cylinder is fixed on the slide of the servo linear guide slide, and the clamping assembly is disposed at the bottom of the piston rod of the lifting cylinder.

[0008] The clamping assembly includes a base frame, a servo geared motor, a gear, a rack, and a clamping block. The base frame is fixed to the piston rod of the lifting cylinder, the servo geared motor is fixed to the base frame, the gear is fixed to the output shaft of the servo geared motor, and racks are symmetrically meshed on both sides of the gear. The racks are slidably connected to the base frame, and a clamping block is fixed to the end of the rack.

[0009] By adopting the above technical solution and setting up a feeding mechanism, after the copper-aluminum finned condenser comes out of the drying component, the servo linear guide slide drives the clamping component to move to the top of the copper-aluminum finned condenser. The lifting cylinder drives the clamping component to move downward. The servo reduction motor in the clamping component works to drive the racks on both sides to move towards the middle through the gears. The racks clamp and fix the copper-aluminum finned condenser through the clamping block. Then the lifting cylinder and the servo linear guide slide reset to remove the copper-aluminum finned condenser from the conveyor line, realizing automatic feeding.

[0010] The end face of the clamping block is fixed with a protective pad.

[0011] The display stand includes a base and limiting rods fixed to the four corners of the base. The base is provided with limiting grooves, and the surface of the base is provided with several through drainage holes.

[0012] Preferably, the air knife is externally connected to a blower, and a heater is also connected to the pipeline between the blower and the air knife.

[0013] By adopting the above technical solution, the heater can be turned on as needed to improve the drying effect.

[0014] In summary, this application includes at least one of the following beneficial technical effects: When the drying device for detecting leakage of copper-aluminum finned condensers in vehicle refrigerators is in operation, the copper-aluminum finned condensers pass through the drying chamber in a vertical position. The air knives in the drying chamber can blow air onto the copper-aluminum finned condensers from both sides. The airflow can pass through the copper-aluminum finned condensers, resulting in a better drying effect. Furthermore, the feeding mechanism enables automatic feeding, which greatly improves production efficiency. Attached Figure Description

Figure 1-4 The system includes a frame 1 and a drying mechanism and a feeding mechanism 4 mounted on the frame 1. The feeding mechanism 4 is located next to the drying mechanism. The drying mechanism includes a conveyor line 2 and a drying assembly 3. The conveyor line 2 is mounted on the frame 1, and the drying assembly 3 is located on top of the conveyor line 2. The conveyor line 2 includes a geared drive motor 21, a drive shaft 22, a driven shaft 23, a plate chain 24, and a placement table 25. The drive shaft 22 and the driven shaft 23 are rotatably connected to the frame 1, and the plate chain 24 is sleeved on the drive shaft 22 and the driven shaft 23. The geared drive motor 21 is fixed on the frame 1 and is used to drive the drive shaft 22 to rotate. Multiple placement tables 25 are evenly installed on the plate chain 24. The geared drive motor 21 is precisely controlled by a servo motor, which can make the conveyor line 2 stop for loading and unloading. The drying assembly 3 includes a drying chamber 31 with openings on both sides. The drying chamber 31 is located at the top of the conveyor line 2. Two air knives 32 are respectively provided on both sides of the inner wall of the drying chamber 31. The orthographic projections of the two air knives 32 are parallel and do not intersect. The drying chamber 31 is connected to an exhaust pipe 33 at the position corresponding to the air knives 32. A blower is connected to the air knives 32, and a heater (not shown in the figure) is also connected to the pipeline between the blower and the air knives 32.

[0022] Reference Figure 1 and Figure 4The unloading mechanism 4 includes a mounting frame 41, a servo linear guide slide 42, a lifting cylinder 43, and a clamping assembly. The mounting frame 41 is fixed on the frame 1, the servo linear guide slide 42 is fixed on the mounting frame 41, and the lifting cylinder 43 is installed on the slide of the servo linear guide slide 42. The clamping assembly includes a base frame 44, a servo geared motor 45, a gear 46, a rack 47, and a clamping block 48. The base frame 44 is fixed to the bottom end of the piston rod of the lifting cylinder 43. The servo geared motor 45 is fixed on the base frame 44. The gear 46 is fixed on the output shaft of the servo geared motor 45. The rack 47 is symmetrically meshed on both sides of the gear 46. The rack 47 is slidably connected to the base frame 44. The end of the rack 47 is fixed with a clamping block 48. The end face of the clamping block 48 is fixed with a protective pad.

[0023] By setting up the unloading mechanism 4, after the copper-aluminum finned condenser comes out of the drying assembly 3, the servo linear guide slide 42 drives the clamping assembly to move to the top of the copper-aluminum finned condenser, and the lifting cylinder 43 drives the clamping assembly to move downward. The servo reduction motor 45 in the clamping assembly works, driving the racks 47 on both sides to move towards the middle through the gear 46.

[0025] The implementation principle of the drying device for detecting air leakage in a copper-aluminum finned condenser of a vehicle refrigerator according to an embodiment of this application is as follows: During operation, the operator places the copper-aluminum finned condenser vertically on the placement platform 25. The conveyor line 2 slowly moves the copper-aluminum finned condenser through the drying chamber 31. During this process, an air knife 32 on one side blows air from the rear of the copper-aluminum finned condenser. The airflow blown out by the air knife 32 can pass through the fins, thereby blowing away the moisture on the fins and copper tubes for initial drying. When the copper-aluminum finned condenser continues to move to the position of another air knife 32, the air knife 32 on that side blows air from the front of the copper-aluminum finned condenser, which can completely dry the moisture remaining on the copper-aluminum finned condenser, greatly improving the drying effect of the copper-aluminum finned condenser.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
