Description

Technical Field

[0001] The invention relates to the technical field of condenser manufacturing, in particular to a manufacturing and assembling device for an automobile condenser. Background Art

[0002] The automobile condenser is a type of heat exchanger. It is mainly responsible for converting the high-temperature, high-pressure gaseous refrigerant discharged from the compressor into liquid high-pressure refrigerant through heat dissipation and cooling. It is generally located at the front end of the vehicle. During the production of the automobile condenser, parts need to be assembled, including the assembly of U-shaped tubes and copper straight tubes on the condenser. After the assembly is completed, welding is required to complete the final U-shaped tube assembly.

[0003] At present, most of the existing U-tube assembly is performed manually, and then the assembly is completed by manual welding. However, due to manual operation, there are certain deviations in the welding positions of different U-tubes during the assembly and welding of the U-tubes, which can easily lead to errors in the assembly of the U-tubes and prevent them from being accurately installed on the vehicle, affecting the vehicle's structural layout. In addition, the uneven arrangement of the U-tubes will cause the refrigerant flow path to be disordered. Some pipes may form local resistance due to abnormal bending angles or uneven spacing, affecting the refrigerant flow rate and flow distribution. During manual assembly, long-term work can easily lead to numbness in the hands, affecting the assembly accuracy and quality of the U-tubes, and the workload is heavy. Summary of the Invention

The condenser 12 is placed on the feed rack 11 and the conveyor belt 16. The top surface of the main frame 1 is fixedly connected to a hollow frame 13, and a transmission mechanism is provided on the top of the hollow frame 13;

[0047] The storage mechanism 2 is arranged on the top side of the main frame 1 and automatically loads and temporarily stores the U-shaped tubes;

[0048] The welding assembly mechanism 4 is arranged on both sides of the connecting plate 3. The welding assembly mechanism 4 includes a power component 41 for material collection and assembly and a monomer stretching welding component 42 that moves synchronously with the power component 41. The monomer stretching welding component 42 includes a limiting rail 421 and a high-frequency welding machine housing 422. The high-frequency welding machine housing 422 is slidably connected to the limiting rail 421. The high-frequency welding machine housing 422 is provided with a plurality of high-frequency welding machine extensions for controlling the welding head 429, and each high-frequency welding machine housing 422 is provided with a first connecting rod 423 and a second connecting rod 424 that are movably connected to the top of each high-frequency welding machine housing 422, and the bottom end is fixedly connected to the welding head 429. The first connecting rod 423 and the second connecting rod 424 between adjacent high-frequency welding machine housings 422 are hinged to each other, and the first connecting rod 423 and the second connecting rod 424 are fixedly connected to the top of the high-frequency welding machine housing 422 near the high-frequency welding machine housing 422. A locking module for controlling the movement relationship between adjacent high-frequency welding machine housings 422 is provided in the external sleeve 425;

[0049] The hydraulic rod 5 is rotatably connected to the top of the transmission mechanism, and its bottom end is coaxially fixedly connected to the connecting plate 3.

[0050] Specifically, when in use, the U-shaped tube is first transported to the storage mechanism 2 for storage, the transmission mechanism controls the power assembly 41 to clamp the U-shaped tube, and the U-shaped tube is lowered and plugged one by one through the power assembly 41. While the U-shaped tube is being inserted, the high-frequency welding machine housing 422 slides and moves downward synchronously on the limiting track 421, and then the U-shaped tube connection is high-frequency welded by the welding head 429. In the process of moving the high-frequency welding machine housing 422, the locking module releases the locking relationship between adjacent high-frequency welding machine housings 422, so that a single high-frequency welding machine housing 422 can move downward synchronously with the power assembly 41, and complete the plug-in and welding steps in sequence, and replace manual operation, thereby avoiding defects in the welding part caused by shaking during welding, and improving the assembly quality of the automobile condenser.

[0051] Reference Figure 1 、 Figure 5 and Figure 7 Specifically, in the embodiment of the present invention, the storage mechanism 2 includes a turntable 21, an arc-shaped limit plate 22, a movable limit plate 23 and a movable clamp 26, and a mounting frame 7 is provided on the top of the main frame 1. Figure 1 As shown, the mounting frame 7 is detachably connected to a servo motor for controlling the rotation of the turntable 21. The turntable 21 is rotatably connected to the mounting frame 7. A plurality of arc-shaped limiting plates 22 are arranged in a circular array on the top of the turntable 21 to prevent the U-shaped tube from tipping over during the rotation of the turntable 21, so as to facilitate the power assembly 41 to accurately take the U-shaped tube. A cavity is provided inside the movable limiting plate 23. The outer wall of the movable limiting plate 23 is slidably connected to the turntable 21. A T-shaped connecting block 24 is fixedly connected between the inner bottom wall of the turntable 21 and the inner top wall of the movable limiting plate 23. A first spring 25 is connected between the T-shaped connecting blocks 24, and a plurality of movable clamps 26 are slidably connected to the turntable 21. The top material of the movable limit plate 23 is magnetic metal. A strong magnet 6 is provided inside the mounting frame 7 close to the side of the U-shaped tube feeding platform 14. The strong magnet 6 is used to control the movement of the movable limit plate 23, thereby facilitating the feeding of the U-shaped tube. It should be noted that the U-shaped tube jacket 414 is matched with the U-shaped tube model. Different U-shaped tubes can be installed and used by replacing different U-shaped tube jackets 414.

[0052] In an embodiment of the present invention, when the U-shaped tube is fed, the servo motor drives the turntable 21 to rotate. When the movable limit plate 23 on the turntable 21 rotates to the top side of the strong magnet 6, the movable limit plate 23 is adsorbed and moved closer to the strong magnet 6 under the action of the strong magnet 6. At this time, the first spring 25 is compressed, and the U-shaped tube enters the movable clamp 26. The movable clamp 26 supports and limits the U-shaped tube. After a U-shaped tube enters the turntable 21, the turntable 21 continues to rotate, and the effect of the strong magnet 6 is lost. The first spring 25 is reset. Under the action of the first spring 25, the movable limit plate 23 rises and blocks the side of the U-shaped tube on the movable clamp 26 to prevent it from tipping over during the rotation of the turntable 21.

[0053] Reference Figure 1 - Figure 3 Specifically, in the embodiment of the present invention, the transmission mechanism includes a motor 131 and a turntable 133. The motor 131 is fixedly installed on the top of the hollow frame 13, and its output shaft is fixedly connected to the turntable 132. The turntable 133 is rotatably connected to the turntable 132.

[0054] In the embodiment of the present invention, the motor 131 controls the rotation of the rotating plate 132 , thereby controlling the rotation of the turntable 133 to complete the determination of the position for taking and placing the U-shaped tube.

[0055] Reference Figure 1 and Figure 4 Specifically, in the embodiment of the present invention, the power assembly 41 includes a rotating rod 411, a second cylinder 412, a synchronous connecting plate 413 and a U-shaped pipe jacket 414. The rotating rod 411 is rotatably connected to the turntable 133. The second cylinder 412 is provided with multiple and is fixedly connected to the connecting disk 3. Its output shaft extends to the inside of the limiting track 421 and is fixedly connected to the synchronous connecting plate 413. The U-shaped pipe jacket 414 is detachably connected to the bottom end of the synchronous connecting plate 413. A socket is provided on the synchronous connecting plate 413, and a plurality of plug blocks of different heights and adapted to the socket are provided on the high-frequency welding machine housing 422, so as to facilitate the adjustment of the distance between the welding head 429 and the U-shaped pipe jacket 414 according to needs, thereby adjusting the welding position of the U-shaped pipe.

[0056] In an embodiment of the present invention, when taking materials, the power assembly 41 moves to the top of the turntable 21, the hydraulic rod 5 moves, pushing the connecting disk 3 to move downward, all U-shaped tube clamps 414 and welding heads 429 are pressed down synchronously, and the welding head 429 presses down the movable limit plate 23 to prevent the welding head 429 from affecting the U-shaped tube clamp 414 from clamping the U-shaped tube, thereby completing the taking of multiple U-shaped tubes at one time.

[0057] Reference Figure 6 Specifically, in the embodiment of the present invention, the locking module includes an insert rod 426, a second spring 428, an elastic rod 43 and a wedge block 44. Two insert rods 426 are provided, one end of which is rotatably connected to the outer wall of the high-frequency welding machine housing 422, and the other end respectively passes through the first connecting rod 423 and the second connecting rod 424 and extends to the inside of the outer sleeve 425. The outer wall of the insert rod 426 is fixedly connected to a positioning block 427 used in conjunction with the wedge block 44, and the inner top wall of the outer sleeve 425 is fixedly connected to the motor 45 The output shaft of the motor 45 is fixedly connected to the connecting baffle 46, and the second spring 428 is fixedly connected to the connecting baffle 46 between the insert rod 426. There are multiple wedge blocks 44, and two wedge blocks 44 of equal height are a group. There are multiple groups along the inner wall of the outer sleeve 425. An elastic rod 43 is connected between the wedge block 44 and the outer sleeve 425. The diameter of the connecting baffle 46 is greater than the distance between the two wedge blocks 44, and the diameter of the insert rod 426 is smaller than the distance between the two wedge blocks 44.

[0058] In the embodiment of the present invention, the connection of adjacent high-frequency welding machine housings 422 is controlled by a locking module. Specifically, when the overall high-frequency welding machine housing 422 needs to be adjusted to the same height, there is no need to unlock the lock. The overall high-frequency welding machine housing 422 is removed as a module and then installed synchronously. When the U-shaped tube is inserted and welded, the motor 45 works to drive the connecting baffle 46 to rotate, so that the positioning block 427 and the wedge block 44 are out of restriction. When the high-frequency welding machine housing 422 moves, the insertion rod 426 passes synchronously between the two wedge blocks 44. At this time, the second spring 428 is in a tensile deformation state. When it needs to be reset, the motor 45 drives the connecting baffle 46 to reset. During the upward movement, the positioning block 427 contacts the wedge block 44, so that the wedge block 44 slides horizontally along the axial direction of the elastic rod 43. When the positioning block 427 is separated from the wedge block 44, under the action of the elastic rod 43, the wedge block 44 is driven to reset to block and support the positioning block 427, thereby enhancing the connection stability of the outer sleeve 425.

[0059] Reference Figure 1 - Figure 3 Specifically, in the embodiment of the present invention, a plurality of equidistantly arranged vertical rods 111 are fixedly connected to the top of the feeding rack 11, and a movable positioning block 112 is detachably connected to each vertical rod 111, and a horizontal limiting rod 113 is detachably connected to the movable positioning block 112.

[0060] In the embodiment of the present invention, a limiting structure arranged parallel to the condenser 12 is formed on both sides of the condenser 12 by the vertical rod 111 and the horizontal limiting rod 113 to ensure that the condenser will not fall from both sides.

[0061] Reference Figure 2 Specifically, in the embodiment of the present invention, a U-shaped tube feeding platform 14 is fixedly connected to the top of the main frame 1, and a first cylinder 15 for fixing the condenser 12 is provided on the top side of the conveyor belt 16.

[0062] In the embodiment of the present invention, during operation, the condenser 12 is clamped by the first cylinder 15 to ensure the stability of the condenser 12 during assembly and ensure the assembly quality. The U-tube feeding platform 14 is responsible for the transportation of the U-tube. The existing technology will not be elaborated on.

[0063] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention.
