Description

Technical Field

[0001] The present invention relates to the technical field of air heater core assembly, and in particular to an automatic assembly device for an air heater core. Background Art

[0002] The heater core is one of the components of the automobile air-conditioning system, and is mainly used for air-conditioning and heating in the cab. The working principle of the heater core is to exchange heat with the engine coolant flowing through the interior through the aluminum core, and blow the hot air out through the air outlet under the action of the blower.

[0003] The existing air heater core is usually composed of heat pipes, heat dissipation strips, side panels and main boards. During assembly, multiple heat pipes are usually manually clamped in the clamping mold and arranged in an intermittent manner. The heat dissipation strips are then placed in the gaps between the heat pipes for filling. Next, the side panels are placed on both sides, and the cylinder is driven to give pressure to the side panels so that the side panels are crimped onto the side walls of the heat pipes. Finally, the main boards on both sides are crimped and clamped to the heat pipes and side panels to complete the assembly. However, the existing clamping mold structure is fixed. When the gap between the heat pipes needs to be adjusted according to the specifications of the heat dissipation strips, it is necessary to replace the clamping molds of different specifications, which is very troublesome and the production cost of purchasing multiple molds is higher. In addition, during assembly, the placement of the heat pipes, heat dissipation strips, side panels and main boards is all done manually, resulting in low assembly efficiency and high labor intensity for workers.

However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific implementation disclosed below.

[0021] Reference Figure 1 - Figure 8 , an automatic assembly device for a wind heating core, comprising a circular base 1, the lower end of which is symmetrically fixedly connected with two frames 2; The clearance adjustment mechanism includes two first mounting blocks 3 symmetrically fixedly connected to the side wall of the return-shaped base 1 through a bracket, the side walls of the two first mounting blocks 3 close to each other are each provided with a first slide groove 4, the inner wall of the first slide groove 4 is slidably connected with a plurality of C-shaped guide blocks 5, the inner wall of the first slide groove 4 is symmetrically fixedly connected with two first guide rods 6, the side walls of the two first guide rods 6 are both slidably connected with the plurality of C-shaped guide blocks 5, the inner wall of the first slide groove 4 is rotatably connected with a first rotating shaft 7, the side wall of the first rotating shaft 7 is provided with a plurality of first arc grooves 8, the side walls of the plurality of C-shaped guide blocks 5 are each fixedly connected with a first ball 9, the first ball 9 is slidably connected with the inner wall of the first arc groove 8, and a power assembly is provided on the return-shaped base 1; An automatic feeding mechanism is installed on the frame 2.

[0022] The automatic feeding mechanism includes a second mounting block 10 fixedly connected to the side wall of the frame 2 through a fixed shaft, a second slide groove 11 is opened at the upper end of the second mounting block 10, a plurality of sliders 12 are slidably connected to the inner wall of the second slide groove 11, and the plurality of sliders 12 are arranged one by one corresponding to the plurality of U-shaped guide blocks 5, two second guide rods 13 are symmetrically fixedly connected to the inner wall of the second slide groove 11, the side walls of the two second guide rods 13 are slidably connected to the plurality of sliders 12, the upper ends of the plurality of sliders 12 are fixedly connected to the first feeding box 14, and the inner wall of the return base 1 is symmetrically slidably connected to the two second feeding boxes 24, the two second The upper end of the loading box 24 is fixedly connected to the limiting guide plate 25, the inner wall of the second slide groove 11 is rotatably connected to the second rotating shaft 15, and the side wall of the second rotating shaft 15 is provided with a plurality of second arc grooves 16, the lower ends of the plurality of sliders 12 are fixedly connected to the second balls 17, and the second balls 17 are slidably connected to the inner wall of the second arc groove 16, the inner walls of the first loading box 14 and the second loading box 24 are sealed and slidably connected to the push plate 18, the inner bottoms of the first loading box 14 and the second loading box 24 are fixedly connected to a plurality of first springs 19, and the upper ends of the plurality of first springs 19 are fixedly connected to the lower end of the push plate 18.

[0023] It should be noted that the specifications of the first rotating shaft 7 and the second rotating shaft 15 and the first arc groove 8 and the second arc groove 16 are the same. The first arc groove 8 and the second arc groove 16 are respectively arranged linearly on the surfaces of the first rotating shaft 7 and the second rotating shaft 15, and are symmetrical in pairs. The closer to the two sides of the first rotating shaft 7 and the second rotating shaft 15, the larger the inclination angle, and the straight-line distance between the starting point and the end point of each first arc groove 8 and the second arc groove 16 is the same. Therefore, when the first rotating shaft 7 and the second rotating shaft 15 rotate, the first arc groove 8 and the second arc groove 16 can be rotated to slide and limit the first ball 9 and the second ball 17, thereby making the distance between the U-shaped guide block 5 and the slider 12 farther or closer.

[0024] The automatic feeding mechanism also includes a plurality of drive boxes 29 fixedly connected to the side wall of the frame 2 through a plurality of brackets, the inner walls of the plurality of drive boxes 29 are sealed and slidably connected with a sliding plug 30, the sliding plug 30 divides the interior of the drive box 29 into a pump air chamber 31 and a connecting chamber 32, and the lower ends of the plurality of drive boxes 29 are fixedly connected with a one-way air inlet pipe 33, and the pump air chamber 31 is connected to the first feeding box 14 and the second feeding box 24 respectively through a one-way air supply pipe 34.

[0025] The power assembly includes a servo motor 20 fixedly connected to the upper end of the circular base 1 through a bracket, one end of the two first rotating shafts 7 penetrates the side wall of the first mounting block 3 and is fixedly connected to a driving wheel 21, the output end of the servo motor 20 is coaxially fixedly connected to one of the first rotating shafts 7, one end of the second rotating shaft 15 penetrates the side wall of the second mounting block 10 and is fixedly connected to a driven wheel 22, the two driving wheels 21 and the driven wheel 22 are connected by a synchronous belt, and two rectangular grooves 23 are symmetrically opened at the upper end of the circular base 1, and the synchronous belt is arranged in the rectangular groove 23.

[0026] It should be noted that the first arc groove 8 and the second arc groove 16 on the first rotating shaft 7 and the second rotating shaft 15 have the same direction, and thus when the first rotating shaft 7 and the second rotating shaft 15 rotate synchronously, the U-shaped guide block 5 and the slider 12 can be driven to move synchronously.

[0027] Furthermore, by driving the servo motor 20 to rotate, the driving wheel 21 and the driven wheel 22 are driven to rotate, and then the two first rotating shafts 7 and the one second rotating shaft 15 are driven to rotate synchronously. Since the first rotating shaft 7 and the second rotating shaft 15 are provided with the first arc groove 8 and the second arc groove 16 on the surface, and the first rotating shaft 7 and the second rotating shaft 15 and the first arc groove 8 and the second arc groove 16 are of the same specifications, when the first rotating shaft 7 and the second rotating shaft 15 rotate, the positions of the first arc groove 8 and the second arc groove 16 will change. Due to the limitation of the first ball 9 and the second ball 17, the multiple U-shaped guide blocks 5 and the multiple sliders 12 will synchronously approach or move away from each other, so that the gap between the U-shaped guide blocks 5 will become larger or smaller, so that it can be used for heat dissipation strips of different specifications, avoid frequent replacement of the clamping mold, and be simpler to use and can also reduce production costs.

[0028] It is worth mentioning that since the slider 12 will move synchronously with the C-shaped guide block 5, and then multiple first loading boxes 14 will move synchronously, it is convenient to cooperate with the C-shaped guide block 5, so that the heat dissipation pipe in the first loading box 14 can be accurately engaged in the C-shaped guide block 5, making the automatic loading more accurate.

[0029] The first loading box 14 and the second loading box 24 are both provided with exhaust holes 28 on their inner walls, and solenoid valves are installed on their inner walls. When the heat dissipation pipes and side panels in the first loading box 14 and the second loading box 24 have been used up, the solenoid valves in the exhaust holes 28 can be energized, and then the solenoid valves can be opened, and the air in the first loading box 14 and the second loading box 24 can be discharged, and the push plate 18 can be reset under the action of the first spring 19, and then the heat dissipation pipes and side panels can be added to the first loading box 14 and the second loading box 24 again.

[0030] The inner walls of the two rectangular grooves 23 are both slidably connected with a first T-shaped rod 26, one end of the first T-shaped rod 26 passes through the inner wall of the circular base 1 and is fixedly connected to the side wall of the second loading box 24, and the side wall of the first T-shaped rod 26 is sleeved with a second spring 27, and the two ends of the second spring 27 are respectively fixedly connected to the side wall of the first T-shaped rod 26 and the inner wall of the rectangular groove 23.

[0031] Two cylinders 35 are symmetrically fixedly connected to the side wall of the circular base 1 through a bracket, and the movable ends of the two cylinders 35 are fixedly connected to an assembly plate 36. A delay switch 37 is fixedly connected to the bottom of one of the drive boxes 29. An indicator light is installed on the circular base 1. The delay switch 37, the indicator light and the external power supply are electrically connected through wires.

[0032] A driving mechanism is installed on the driving box 29, and the driving mechanism includes a second T-bar 47 slidably connected to the upper end of the driving box 29, the lower end of the second T-bar 47 passes through the upper end of the driving box 29 and is fixedly connected to the upper end of the sliding plug 30, the side wall of the second T-bar 47 is sleeved with a fourth spring 48, the two ends of the fourth spring 48 are respectively fixedly connected to the top of the driving box 29 and the upper end of the sliding plug 30, and the multiple second T-bars 47 are fixedly connected by multiple fixing rods 49. Two vertical plates 50 are symmetrically fixedly connected to the lower end of the circular base 1, and the side walls of the two vertical plates 50 close to each other are connected to a third rotating shaft 51 for common rotation. The side wall of the third rotating shaft 51 is fixedly connected to a cam 52, and the upper end of the circular base 1 is fixedly connected to a motor 53 through a bracket, and the output end of the motor 53 passes through the side wall of the vertical plate 50 and is fixedly connected to the third rotating shaft 51.

[0033] Furthermore, the driving motor 53 rotates, driving the third rotating shaft 51 to rotate, and then driving the cam 52 to rotate, squeezing the second T-shaped rod 47. Since the second T-shaped rods 47 are connected by the fixing rod 49, all the second T-shaped rods 47 will move synchronously. In conjunction with the plurality of fourth springs 48, the second T-shaped rod 47 will drive the sliding plug 30 to first slide downward in the driving box 29 in a sealed manner, and then the air in the pump air cavity 31 will be squeezed into the first loading box 14 and the second loading box 24 through the one-way air supply pipe 34, thereby pushing the push plate 18 to slide upward for a distance, so that the uppermost heat dissipation pipe in the first loading box 14 and the uppermost side plate in the second loading box 24 are pushed out, and the heat dissipation pipe will be engaged in the U-shaped guide block 5, and the side plate The plate will enter the limit guide plate 25 and fit with the heat pipes on both sides. When the slide plug 30 slides to abut against the delay switch 37, the loading is completed and the delay switch 37 will be turned on for five seconds, so that the indicator light is on. When the staff observes that the indicator light is on, they can manually operate the motor 53 to stop running, and then put a plurality of heat dissipation strips between the heat dissipation pipes. After placement, start the motor 53 and start the cylinder 35 synchronously. The cylinder 35 extends, which will drive the two assembly plates 36 to move close to the side plate, and then press the side plate against the side wall of the heat dissipation pipe. The loading can be completed automatically without manual placement of the heat dissipation pipe and the side plate. Some processes can be automated, reducing the labor intensity of workers and improving assembly efficiency.

[0034] A flattening mechanism is installed on the first mounting block 3, and the flattening mechanism includes a vertical cylinder 38 fixedly connected to the upper end of the first mounting block 3, a slide plate 39 is slidably connected to the inner wall of the vertical cylinder 38, a connecting rod 40 is fixedly connected to the upper end of the slide plate 39, and a slide cylinder 41 is fixedly connected to the other end of the connecting rod 40, a third spring 42 is fixedly connected between the bottom of the vertical cylinder 38 and the slide plate 39, a circular plate 43 is sealingly slidably connected to the inner wall of the slide cylinder 41, a push rod 44 is fixedly connected to the lower end of the circular plate 43, the lower end of the push rod 44 passes through the lower end of the slide cylinder 41 and is fixedly connected to the pressure plate 45, and the connecting chamber 32 is connected to the slide cylinder 41 through a connecting pipe 46.

[0035] Furthermore, during the crimping assembly, the rotation of the motor 53 will continue to drive the cam 52 to rotate, and the slide plug 30 will slide upward, and the air in the connecting chamber 32 will be squeezed into the slide cylinder 41 through the connecting tube 46, pushing the circular plate 43 to move downward, driving the push rod 44 to move downward, and then driving the pressure plate 45 to move downward, and then the pressure plate 45 will press the upper surface of the air heater core to keep its upper surface flat, to avoid the heat sink being squeezed out of the gap when the side plate is crimped, thereby reducing the quality of the air heater core.

[0036] It is worth mentioning that after the crimping is completed, the driving cylinder 35 contracts, driving the assembly plate 36 to reset. At this time, the motor 53 will continue to rotate, driving the cam 52 to operate, thereby causing the slide plug 30 to slide downward for the next loading. When the slide plug 30 slides downward, the air in the slide cylinder 41 will be drawn back into the connecting chamber 32 through the connecting pipe 46, thereby causing the pressing plate 45 to move upward and reset. In addition, when the heat dissipation pipe and the side plate move upward again for loading, the previously crimped air heater core will be pushed upward by the heat dissipation pipe and the side plate, and then the crimped air heater core will move upward. When it is in contact with the pressing plate 45, When the material is in place, the height of the lower surface of the air-heating core is higher than the upper end of the limit guide plate 25, and the operating motor 53 stops running. At this time, the staff can take out the assembled air-heating core. Since the motor 53 stops running at this time, it will be safer for the workers to take out the materials. After the air-heating core is taken out, the slide plate 39 will be quickly reset under the action of the third spring 42, thereby driving the slide cylinder 41 and the pressure plate 45 to quickly reset, and then the next air-heating core can be assembled.

[0037] A plurality of rubber plates 54 are fixedly connected between the plurality of first loading boxes 14 . The rubber plates 54 can be stretched and deformed to cover the gaps between the first loading boxes 14 , thereby preventing the filled heat dissipating strips from falling from the gaps between the first loading boxes 14 .

[0038] In the present invention, firstly, the placement gap between the heat dissipation pipes is adjusted according to actual needs so as to be able to adapt to the specifications of the heat dissipation strips. By driving the servo motor 20 to rotate, the driving wheel 21 and the driven wheel 22 are driven to rotate, and then the two first rotating shafts 7 and the one second rotating shaft 15 are driven to rotate synchronously. Since the first rotating shaft 7 and the second rotating shaft 15 are provided with the first arc groove 8 and the second arc groove 16 on the surface, and the first rotating shaft 7 and the second rotating shaft 15 and the first arc groove 8 and the second arc groove 16 are of the same specifications, when the first rotating shaft 7 and the second rotating shaft 15 rotate, the position of the first arc groove 8 and the second arc groove 16 will change. Due to the limitation of the first ball 9 and the second ball 17, the multiple U-shaped guide blocks 5 and the multiple sliders 12 will synchronously approach or move away from each other, so that the gap between the U-shaped guide blocks 5 will become larger or smaller, and the slider 12 will drive the multiple first loading boxes 14 to move synchronously, so as to facilitate the cooperation with the U-shaped guide block 5, so that the heat dissipation pipes in the first loading box 14 can be accurately engaged in the U-shaped guide block 5.

[0039] When the U-shaped guide block 5 moves, the two second loading boxes 24 will always fit with the first loading boxes 14 on both sides under the action of the second spring 27. When the side plate enters the limiting guide plate 25 during loading, the side plate will fit with the side walls of the heat dissipation pipes on both sides, thereby facilitating crimping.

[0040] When the gap between the U-shaped guide blocks 5 is adjusted, the driving motor 53 rotates, driving the third rotating shaft 51 to rotate, and then driving the cam 52 to rotate, squeezing the second T-shaped rod 47. Since the second T-shaped rods 47 are connected by the fixing rod 49, all the second T-shaped rods 47 will move synchronously. In conjunction with the plurality of fourth springs 48, the second T-shaped rod 47 will drive the sliding plug 30 to first slide downward in the driving box 29 in a sealed manner, and then the air in the pump air cavity 31 will be squeezed into the first loading box 14 and the second loading box 24 through the one-way air supply pipe 34, thereby pushing the push plate 18 to slide upward for a distance, so that the uppermost heat dissipation pipe in the first loading box 14 is The top side panel in the second loading box 24 is pushed out, the heat dissipation tube will be engaged into the U-shaped guide block 5, and the side panel will enter the limit guide plate 25 and fit with the heat dissipation tubes on both sides. When the slide plug 30 slides to abut against the delay switch 37, the loading is completed, and the delay switch 37 will be turned on for five seconds, so that the indicator light will be on. When the staff observes that the indicator light is on, they can manually operate the motor 53 to stop running, and then put a plurality of heat dissipation strips between the heat dissipation tubes. After placing them, start the motor 53 and start the cylinder 35 synchronously. The cylinder 35 will extend, which will drive the two assembly plates 36 to move close to the side panels, and then press the side panels against the side walls of the heat dissipation tubes.

[0041] In addition, during the crimping assembly, the rotation of the motor 53 will continue to drive the cam 52 to rotate. At this time, the slide plug 30 will slide upward, and the air in the connecting chamber 32 will be squeezed into the slide cylinder 41 through the connecting tube 46, pushing the circular plate 43 to move downward, driving the push rod 44 to move downward, and then driving the pressure plate 45 to move downward, and then the pressure plate 45 will press the upper surface of the air heater core to keep its upper surface flat, to avoid the heat sink being squeezed out of the gap when the side plate is crimped, thereby reducing the quality of the air heater core.

[0042] After the crimping is completed, the driving cylinder 35 contracts, driving the assembly plate 36 to reset. At this time, the motor 53 will continue to rotate, driving the cam 52 to operate, thereby causing the slide plug 30 to slide downward for the next loading. When the slide plug 30 slides downward, the air in the slide cylinder 41 will be drawn back into the connecting chamber 32 through the connecting pipe 46, thereby causing the pressing plate 45 to move upward and reset. In addition, when the heat dissipation pipe and the side plate move upward again for loading, the previously crimped air heater core will be pushed upward by the heat dissipation pipe and the side plate, and then the crimped air heater core will move upward, and when it abuts against the pressing plate 45, An upward force is given to the pressure plate 45, which in turn pushes the slide 41 to move upward, driving the slide plate 39 to slide upward. When the material is in place, the height of the lower surface of the air heating core is already higher than the upper end of the limit guide plate 25, and the operating motor 53 stops running. At this time, the staff can take out the assembled air heating core. Since the motor 53 stops running at this time, it will be safer for the workers to take materials. After the air heating core is taken out, the slide plate 39 will quickly reset under the action of the third spring 42, thereby driving the slide 41 and the pressure plate 45 to quickly reset, and then the next air heating core can be assembled.

[0043] When the heat dissipation tubes and side panels in the first loading box 14 and the second loading box 24 have been used up, the solenoid valve in the exhaust hole 28 can be energized, and then the solenoid valve opens, the air in the first loading box 14 and the second loading box 24 is discharged, and the push plate 18 is reset under the action of the first spring 19, and then the heat dissipation tubes and side panels can be added to the first loading box 14 and the second loading box 24 again.

[0044] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
