Description

Technical Field

[0001] This application relates to the field of automotive assembly technology, and in particular to an assembly station and process for two air conditioning units. Background Technology

[0002] During the assembly of an automotive air conditioning unit, the evaporator and condenser need to be installed into their corresponding cavities. After installation, the pipe joints of the evaporator and condenser need to be covered with a soft material such as foam. Both the evaporator and condenser have relatively thin and long pipes, and the relative positions of these pipes often have significant errors during assembly. This can make it difficult for the foam material to adhere properly to the pipe joints, resulting in a decrease in the overall assembly quality of the two components. Summary of the Invention

[0003] In order to improve the assembly quality of the air conditioner's two components, this application provides an assembly station and process for the air conditioner's two components.

[0004] The technical solution provided in this application for an air conditioning unit two-phase assembly station adopts the following:

[0005] Firstly, this application provides an assembly station for two air conditioning units.

[0006] An air conditioning unit assembly station includes a work frame, a robotic arm mounted on the work frame, an assembly line, evaporator assembly parts, and a pipe connection assembly for the two evaporators.

[0007] The robotic arm includes a robotic arm mounted on the working frame, an evaporator gripper and a condenser assembly mounted on the robotic arm; the production line is used to transport air conditioning units.

[0008] The two-device pipe head connection assembly includes a two-device pipe clamping component, a hexagonal nut tightening component, and a sponge bonding component;

[0009] The pipe clamping device for the two evaporators includes a 39th cylinder, a 40th cylinder, a second upper clamping block, and a second lower clamping block. The 39th cylinder is mounted on the working frame and faces the production line. The 40th cylinder is vertically mounted on the telescopic end of the 39th cylinder. The second upper clamping block is mounted on the cylinder body of the 40th cylinder. The second lower clamping block is mounted on the telescopic end of the 40th cylinder. The second upper clamping block and the second lower clamping block can clamp the pipes of the evaporator and the condenser.

[0010] The hexagonal nut tightening device includes a forty-fourth cylinder mounted on the working frame and a second screw gun mounted on the telescopic end of the forty-fourth cylinder. The telescopic direction of the forty-fourth cylinder is the same as that of the thirty-ninth cylinder. The second screw gun can tighten the nut at the pipe joint connection between the evaporator and the condenser.

[0011] The sponge bonding component can attach the sponge to the pipe joint connection between the evaporator and the condenser.

[0012] By adopting the above technical solution, when assembling the evaporator and condenser, the assembly line first transports the air conditioning unit to the assembly position. Then, the robotic arm rotates, the evaporator clamping component picks up the evaporator, and the condenser assembly component picks up the condenser. Next, the evaporator assembly component assembles the evaporator held by the evaporator clamping component onto the air conditioning unit, and the condenser assembly component assembles the condenser onto the air conditioning unit. Then, the extension end of the 39th cylinder extends, and the extension end of the 40th cylinder retracts. The second upper clamping block and the second lower clamping block clamp the pipes of the evaporator and condenser. Then, the extension end of the 44th cylinder extends, and the second screw gun tightens the nut at the pipe joint connection between the evaporator and condenser. Finally, the sponge applicator attaches a sponge to the pipe joint connection between the evaporator and condenser, thus completing the installation of the two components.

[0013] During the process described above, when connecting the pipe joints of the evaporator and condenser, the second upper clamping block and the second lower clamping block can limit the pipe position, reducing the possibility of excessive relative positional offset between the two pipes, thereby ensuring the accuracy of assembly and improving the assembly quality of the two air conditioners.

[0014] Optionally, the air conditioning unit assembly station also includes upper and lower guide components, which include a fifth linear guide rail, a thirtieth cylinder, a positioning plate, a thirty-first cylinder, a thirty-second cylinder, an upper guide plate, and a lower guide plate.

[0015] The fifth linear guide rail is mounted on the working frame, the thirtieth cylinder is mounted on the slider of the fifth linear guide rail, the positioning plate is vertically mounted on the telescopic end of the thirtieth cylinder, the thirty-first cylinder and the thirty-second cylinder are symmetrically mounted on the telescopic end of the thirtieth cylinder, the upper guide plate and the lower guide plate are respectively mounted on the telescopic ends of the thirty-first cylinder and the thirty-second cylinder, and the upper guide plate and the lower guide plate can move closer to or further away from each other and can respectively contact the upper and lower sides of the evaporator.

[0016] By adopting the above technical solution, when assembling the evaporator, the slider of the fifth linear guide slides, and the telescopic end of the thirtieth cylinder extends, which can drive the positioning plate closer to the evaporator. Then, the telescopic ends of the thirty-first and thirty-second cylinders extend, which allows the upper guide plate and the lower guide plate to move closer to each other, so that the upper guide plate abuts against the upper side of the evaporator and the lower guide plate abuts against the lower side of the evaporator, thereby achieving the positioning of the evaporator assembly and effectively ensuring the accuracy of the evaporator assembly.

[0017] Optionally, the air conditioning unit assembly station also includes a side guide component, which includes a 33rd cylinder, a 34th cylinder, a 6th linear guide rail, and a side guide plate.

[0018] The thirty-third cylinder is vertically mounted on the working frame, the thirty-fourth cylinder is horizontally mounted on the telescopic end of the thirty-third cylinder, the sixth linear guide rail is vertically mounted on the telescopic end of the thirty-fourth cylinder, the side guide plate is mounted on the slider of the sixth linear guide rail, and the side guide plate can contact one side wall of the evaporator.

[0019] By adopting the above technical solution, when assembling the evaporator, the telescopic end of the 33rd cylinder retracts, the telescopic end of the 34th cylinder extends, and the slider of the 6th linear guide rail drives the side guide plate to slide, so that the side guide plate can abut and guide one side wall of the evaporator, thereby further improving the accuracy of evaporator assembly.

[0020] Optionally, the air conditioning unit assembly station also includes a condenser guide assembly, which includes a guide plate disposed on the working frame and a thirty-sixth cylinder, a thirty-seventh cylinder and a thirty-eighth cylinder disposed on the guide plate.

[0021] The guide plate has an open guide opening. The thirty-sixth cylinder and the thirty-seventh cylinder are located on both sides of the guide opening, and the thirty-eighth cylinder is located at one end of the guide opening. A condenser guide plate is provided on the telescopic ends of the thirty-sixth cylinder, the thirty-seventh cylinder and the thirty-eighth cylinder.

[0022] By adopting the above technical solution, when the condenser is assembled, the telescopic ends of the 36th, 37th and 38th cylinders extend, allowing the condenser guide plate to abut against the side walls of the condenser, thereby limiting the assembly position of the condenser and ensuring the accuracy of the condenser assembly.

[0023] Optionally, the air conditioning unit assembly station also includes a secondary evaporator positioning component. The secondary evaporator positioning component includes a first positioning support plate disposed on the working frame, a first positioning frame disposed on the first positioning support plate, a fourth cylinder, and a fifth cylinder. The evaporator can be placed in the first positioning frame, and the fourth cylinder and the fifth cylinder can respectively abut against one side and one end of the evaporator.

[0024] By adopting the above technical solution, when the telescopic ends of the fourth and fifth cylinders extend, they can abut against the evaporator in the first positioning frame, thereby performing secondary positioning of the evaporator to ensure more accurate clamping during assembly, and thus improve the accuracy of evaporator assembly.

[0025] Optionally, the air conditioning unit assembly station also includes a secondary condenser positioning component. The secondary condenser positioning component includes a second positioning support plate disposed on the working frame, a second positioning frame disposed on the second positioning support plate, a sixth cylinder, and a seventh cylinder. The condenser can be placed in the second positioning frame, and the sixth cylinder and the seventh cylinder can respectively abut against one side and one end of the evaporator.

[0026] By adopting the above technical solution, when the telescopic ends of the sixth and seventh cylinders extend, they can abut against the condenser in the second positioning frame, thereby performing secondary positioning of the condenser to ensure more accurate clamping during assembly, and thus improve the accuracy of condenser assembly.

[0027] Optionally, the air conditioning unit assembly station may also include an evaporator material rack and a condenser material rack disposed on the working frame.

[0028] By adopting the above technical solution, the evaporator can be temporarily stored on the evaporator material rack, and the condenser can be stored on the condenser material rack, so that the evaporator and condenser can be accessed at any time, thereby improving the convenience of assembling the two devices.

[0029] Optionally, the evaporator assembly includes a 24th cylinder vertically mounted on the working frame, a 25th cylinder horizontally mounted on the telescopic end of the 24th cylinder, a 26th cylinder horizontally mounted on the telescopic end of the 25th cylinder, and a third gripper mounted on the telescopic end of the 26th cylinder, the third gripper being capable of gripping the evaporator.

[0030] By adopting the above technical solution, when assembling the evaporator, the telescopic ends of the 24th and 25th cylinders extend and retract accordingly to adjust the position of the 26th cylinder. Then, the telescopic end of the 26th cylinder extends, allowing the evaporator held by the third gripper to be assembled onto the air conditioning unit. The evaporator on the third gripper is then picked up by the evaporator clamping component.

[0031] Optionally, the condenser assembly includes a third cylinder mounted on the robotic arm and a second gripper mounted on the telescopic end of the third cylinder, the second gripper being capable of assembling the condenser.

[0032] By adopting the above technical solution, when the telescopic end of the third cylinder extends, it drives the second gripper to extend, and then the second gripper can grasp the condenser. After the robotic arm moves to the air conditioning unit, the condenser can be installed in the corresponding position on the air conditioning unit.

[0033] Secondly, this application provides a two-component assembly process for an air conditioning unit.

[0034] An assembly process for two components of an air conditioning unit includes the following steps:

[0035] After the production line transports the air conditioning unit to the assembly position, the square nut vibrating loading component loads the square nut, and the fifth gripper installs the square nut onto the air conditioning unit; then the first gripper clamps the evaporator to the evaporator secondary positioning component for secondary positioning, and then the first gripper clamps the evaporator to the evaporator assembly component, and then the evaporator assembly component pushes the evaporator laterally into the air conditioning unit. During the pushing process, the evaporator is guided by multiple evaporator auxiliary assembly components;

[0036] Then the pipe clamp vibrating feeding component feeds the pipe clamp, the first screw gun drives the bolt into the air conditioning unit, so that the pipe clamp positions the evaporator pipe. Then the second jaw clamps the condenser to the condenser secondary positioning component for secondary positioning. Then the second jaw clamps the condenser and pushes it into the air conditioning unit. During the pushing process, the condenser is guided by the condenser guide component.

[0037] Then, the pipe clamping device clamps the pipes of the condenser and evaporator. The second screw gun installs the hexagonal nut at the pipe joint of the evaporator and condenser. Then, the sponge is attached to the pipe joint of the evaporator and condenser using the sponge attaching device.

[0038] In summary, the beneficial technical effects of this application are as follows: during the assembly process of the evaporator and condenser, the clamping components for the pipes of the two units can clamp and limit the pipes of the evaporator and condenser, thereby reducing the error between the pipes of the evaporator and condenser, and thus helping to improve the quality of the assembly of the two air conditioning units.

The telescopic ends of the thirty-sixth cylinder 95, the thirty-seventh cylinder 96, and the thirty-eighth cylinder 97 are all fixedly connected to the condenser guide plate.

[0085] When the second gripper 26 is vertically assembling the condenser, the telescopic end of the thirty-fifth cylinder 92 moves downward, and the sliding guides 93 of the two seventh linear guides move downward, thereby driving the sliding guide plate 94 to move closer to the air conditioning unit. Then, the thirty-sixth cylinder 95, the thirty-seventh cylinder 96, and the thirty-eighth cylinder 97 drive multiple condenser guide plates to extend, and the condenser guide plates abut against the condenser, thereby guiding the condenser to ensure the accuracy of condenser assembly.

[0086] Reference Figure 16 The dual-unit pipe connection assembly 10 includes a support frame, a dual-unit pipe clamping component, a hexagonal nut tightening component, and a sponge bonding component. The support frame and hexagonal nut tightening component are both mounted on the working frame, while the dual-unit pipe clamping component and sponge bonding component are located on the support frame. The dual-unit pipe clamping component clamps the pipes of the evaporator and condenser, the hexagonal nut tightening component tightens the hexagonal nuts used to connect the pipe joints of the evaporator and condenser, and the sponge bonding component applies sponge to the pipe joint positions of the evaporator and condenser.

[0087] The evaporator and condenser pipe clamping assembly includes a 39th cylinder 101, a 40th cylinder 102, a second upper clamping block 103, and a second lower clamping block 104.

When the telescopic end of the 39th cylinder 101 extends, it allows the 40th cylinder 102 to extend. When the telescopic end of the 40th cylinder 102 retracts, it allows the second upper clamping block 103 and the second lower clamping block 104 to come closer together, thereby clamping the evaporator and condenser pipes to facilitate tightening the hexagonal nuts and attaching the sponge.

[0088] The hexagonal nut tightening device includes cylinder 105 (41st), cylinder 106 (42nd), cylinder 107 (43rd), cylinder 108 (44th), and a second screw gun 109.

The second screw gun 109 is fixedly connected to the telescopic end of cylinder 108 via a bracket. When the telescopic ends of cylinders 105 (forty-first), 106 (forty-second), 107 (forty-third), and 108 (forty-fourth) extend or retract, the position of the second screw gun 109 can be adjusted accordingly, thereby tightening the hexagonal nut.

[0089] The sponge bonding component includes a 45th cylinder 1010, a triangular plate 1011, and three 46th cylinders 1012. The 45th cylinder 1010 is fixedly connected to the support frame.

The three 46th cylinders 1012 are respectively fixedly connected to the three corners of the triangular plate 1011, with the telescopic ends of the 46th cylinders 1012 facing the center of the triangular plate 1011. After the evaporator and condenser pipes are clamped, the telescopic end of the 45th cylinder 1010 extends, followed by the telescopic ends of the three 46th cylinders 1012, thus bonding the sponge to the pipe joints of the evaporator and condenser. Because the installation accuracy of the evaporator and condenser is improved, and the pipes of the evaporator and condenser are limited, the bonding effect of the sponge is improved, thereby effectively improving the assembly quality of the two air conditioning units.

[0090] Based on the same inventive concept, this application also provides an assembly process for two components of an air conditioning unit.

[0091] The assembly process of the air conditioning unit includes the following steps:

[0092] First, after the air conditioning unit is conveyed to the workstation by the assembly line 5, the square nut vibrating feeder feeds the square nut, and the fifth gripper 718 installs the square nut onto the air conditioning unit. Then, the first gripper 24 on the robotic arm clamps the evaporator to the evaporator secondary positioning component for secondary positioning. After that, the first gripper 24 on the robotic arm clamps the evaporator to the evaporator assembly. Then, the evaporator assembly pushes the evaporator laterally into the air conditioning unit. During the pushing process, the evaporator is guided by multiple evaporator auxiliary assemblies.

[0093] Next, the pipe clamp vibrating feeder loads the pipe clamp, and then the first screw gun 714 drives the bolt into the air conditioning unit, positioning the evaporator pipes with the pipe clamp. Then, the second gripper 26 on the robotic arm clamps the condenser to the condenser secondary positioning component for secondary positioning. After that, the second gripper 26 on the robotic arm clamps the condenser again and pushes it into the air conditioning unit. During the pushing process, the condenser is guided by the condenser guide assembly 9.

[0094] Next, the pipe clamping device clamps the pipes of the condenser and evaporator, and the second screw gun 109 installs the hexagonal nut at the pipe joint of the evaporator and condenser. Then, the sponge is attached to the pipe joint of the evaporator and condenser by the sponge attaching device.

[0095] 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.
