[0048] See also Figures 1 to 3 , Figure 1 and Figure 2 This is a structural diagram of the vehicle air conditioning controller. Figure 2Figure 1 is a schematic diagram of the structure of FPC 100. The vehicle air conditioning controller is a component of a car, used to control the vehicle's air conditioning system, achieving cooling, heating, ventilation, and air purification within the vehicle cabin. Existing vehicle air conditioning controllers typically include FPC 100, a panel 200, a middle box 300, a PCB 400, and a rear cover 500. With rising living standards and increasing demand for automobiles, mass production of vehicle air conditioning controllers has become essential. However, in the production process of vehicle air conditioning controllers, component assembly and handling of semi-finished products are mostly performed manually, resulting in low assembly efficiency and difficulty meeting the needs of mass production.

[0049] To this end, an embodiment of the present invention proposes an assembly production line for a vehicle-mounted air-conditioning controller, aiming to improve the assembly production efficiency of the vehicle-mounted air-conditioning controller to meet the needs of mass production.

[0050] See also Figures 4 to 8 , the vehicle air conditioning controller assembly line includes:

[0051] The FPC assembly section 1 includes a chip feeding device 11 and a chip fixing device 12, which are arranged in sequence. The chip feeding device 11 is used to assemble the chip 100a to the FPC substrate 100b, and the chip fixing device 12 is used to fix the assembled chip 100a to the FPC substrate 100b.

[0052] The middle box assembly section 2 is provided on one side of the FPC assembly section 1. The middle box assembly section 2 includes an oiling device 21 and a first pressing device 22, which are arranged in sequence. The oiling device 21 is used to apply oil to the slider 300c. The first pressing device 22 is used to press the light guide 300b and the oiled slider 300c into the middle box body 300a.

[0053] The panel assembly section 3 is connected to the middle box assembly section 2. The panel assembly section 3 includes a welding device 31, a first manipulator 32, and a second pressing device 33, which are arranged in sequence. The welding device 31 is used to weld the chip sensor 200b to the panel body 200a. The first manipulator 32 is used to transport the assembled FPC 100 from the FPC assembly section 1 to the second pressing device 33. The second pressing device 33 is used to press the panel 200 and the FPC 100 into the middle box 300.

[0054] The back cover assembly section 4 is connected to the panel assembly section 3. The back cover assembly section 4 includes a loading device 41 and a locking device 42 arranged in sequence. The loading device 41 is used to separate the PCB400 into panels and convey it to the locking device 42. The locking device 42 is used to lock the back cover 500 on the middle box 300 with the panel 200 and FPC100 pressed in after the PCB400 is assembled into the middle box 300.

[0055] The FPC assembly section 1 of this embodiment is used to assemble FPC100. Specifically, the chip feeding device 11 is used to assemble the chip 100a to the FPC substrate 100b, wherein the feeding method of the chip 100a can adopt a vibration plate to transport the chip 100a for loading, a robot to grab the chip 100a for loading, or a combination of a vibration plate and a robot to load. Among them, when the combination of a vibration plate and a robot is adopted, the vibration plate transports the chip 100a to a preset position, and the robot grabs the chip 100a from the preset position to the FPC substrate 100b to complete the assembly. Preferably, a visual positioning camera can be set on one side of the robot to improve the accuracy of the robot's grabbing action. After the chip 100a is assembled to the FPC substrate 100b, the chip fixing device 12 fixes the chip 100a on the FPC substrate 100b. The fixing method can be snap-fitting, riveting or other connection methods. Specifically, a fixing frame can be used to cover the chip 100a on the FPC substrate 100b, and the fixing frame and the substrate are riveted or snap-fitted to fix the chip 100a on the FPC substrate 100b.

[0056] The middle box assembly section 2 of this embodiment is provided on the side where the FPC 100 is assembled, and is used to assemble the middle box 300. Specifically, the oiling device 21 is used to oil the slider 300c. During the use of the vehicle air conditioning controller, the slider 300c and the middle box body 300a slide relative to each other. Therefore, it is necessary to apply lubricating oil to the slider 300c before the slider 300c is installed in the middle box body 300a. The oiling device 21 can be provided with a manipulator and an oil spray nozzle to oil the slider 300c. After the manipulator drives the oil spray nozzle to a preset position, the oil spray nozzle sprays lubricating oil onto the slider 300c. Preferably, a visual inspection camera is provided on one side of the oil spray nozzle to detect whether the oiling position of the slider 300c has been oiled to avoid missing oil. After the slider 300c is oiled, the first pressing device 22 presses the light guide 300b and the slider 300c into the middle box body 300a. The first pressing device 22 may be provided with a robot and a pressing block. After the robot installs the light guide column 300b and the slider 300c into the middle box body 300a, the pressing block presses the light guide column 300b and the slider 300c under the action of a driving force.

[0057] The panel assembly section 3 of this embodiment is connected to the middle box assembly section 2 and is used to assemble the panel 200. Specifically, the welding device 31 is used to weld the chip sensor 200b and the panel body 200a. The panel body 200a is made of plastic, so ultrasonic welding can be used as the welding method. The chip sensor 200b and the panel body 200a are first attached manually or by a robot. The surface of the panel body 200a in contact with the chip sensor 200b is melted by the action of ultrasound, and the welding is completed after cooling. The first robot 32 transports the assembled FPC100 from the FPC assembly section 1 to the second pressing device 33. After the manual or robot assembles the FPC100 and the panel 200, the second pressing device 33 presses the FPC100 and the panel 200 into the middle box 300. The second pressing device 33 may be provided with a robot and a pressing block. After the robot installs the panel 200 and the FPC 100 into the middle box 300 , the pressing block presses the panel 200 and the middle box 300 under the action of a driving force.

[0058] In this embodiment, the rear cover assembly section 4 is connected to the panel assembly section 3 and is used to assemble the PCB 400 and the rear cover 500. Specifically, the loading device 41 can be equipped with a PCB 400 separation device and a conveyor belt. The conveyor belt 412 is connected to the separation device. After the separation device separates the PCB 400, the conveyor belt transports the individual PCBs 400 to the locking device 42. The locking device 42 can be equipped with a robot and an electric screwdriver 423. After the robot assembles the PCB 400 and the rear cover 500 into the middle box 300, the electric screwdriver 423 drives the screws between the rear cover 500 and the middle box 300, thereby locking the rear cover 500 to the middle box 300.

[0059] In summary, the present invention achieves automated assembly and production of vehicle air conditioning controllers through the FPC assembly section 1, the middle box assembly section 2, the panel assembly section 3, and the rear cover assembly section 4. Compared to existing technologies, the present invention uses automated equipment to assemble product components and a robot to transport semi-finished products, reducing manual operations and improving assembly efficiency of vehicle air conditioning controllers, thus meeting the needs of mass production of vehicle air conditioning controllers.

[0060] See also Figure 9 In some embodiments, the FPC assembly section 1, the middle box assembly section 2, the panel assembly section 3 and the back cover assembly section 4 are all provided with a conveying device 5, and the conveying device 5 includes a return-forming assembly line 51 and a product carrier board 52 provided on the return-forming assembly line 51, and the return-forming assembly line 51 is used to drive the product carrier board 52 to reflow on the return-forming assembly line 51.

[0061] In this embodiment, the conveyor device 5 is used to transport products between assembly devices. Specifically, the circular assembly line 51 is equipped with a drive motor and rollers or belts connected to the drive motor. The rollers or belts are coupled to a product carrier 52 to drive the product carrier 52 back on the circular assembly line 51. The product carrier 52 is used to hold the vehicle air conditioning controller and its components. The product carrier 52 is provided with several assembly positions, each with a structure that matches the structure of the product.

Optionally, the conveyor device 5 also includes a blocking mechanism and a lifting mechanism provided on the circular assembly line 51. The blocking mechanism is used to prevent the product carrier 52 from continuing to flow, and the lifting mechanism is used to lift the product carrier 52, separating the product carrier 52 from the circular assembly line 51 and restraining the product carrier 52 in a specific assembly position. The lifting mechanism can be installed at each assembly device and located directly below the product carrier 52. When the product carrier 52 transports the product to an assembly device, the blocking mechanism blocks the product carrier 52 and the lifting mechanism lifts the product carrier 52, thereby confining the product carrier 52 to a preset assembly position, facilitating the assembly of the product by the assembly device.

In this embodiment, the chip 100a is in the form of a strip, one end of which is wound within the unwinding reel 1111 and the other end passes through two guide posts and extends to the loading platform 1112. A second manipulator 112 is located on one side of the unwinding assembly 111 and is used to grab the chip 100a from the loading platform 1112 and place it on the first assembly position 521 of the product carrier 52. Optionally, a placement head is provided at the end of the second manipulator 112, which is equipped with a suction nozzle for picking up the chip 100a. When chip 100a is fed, the motor drives the guide column to rotate, causing the strip of chip 100a to be unwound from the unwinding disk 1111 and extended to the loading platform 1112. The second robot 112 drives the nozzle of the placement head to pick up chip 100a and place chip 100a on the FPC substrate 100b located at the first assembly position 521. Optionally, a first vision positioning camera 1121 is provided on one side of the placement head, and a second vision positioning camera 1113 is provided on one side of the loading platform 1112. During the process of second robot 112 picking up chip 100a, when the first vision positioning camera 1121 and the second vision positioning camera 1113 are facing each other, the nozzle of the placement head is aligned with chip 100a, thereby completing the precise picking and positioning action. Optionally, the second robot 112 is a six-axis robot.

[0065] See also Figure 3 and Figure 11 In some embodiments, the FPC 100 further includes a housing bracket 100c, and the chip fixing device 12 includes a rivet head 121 that can move up and down. A fixture 122 for placing the housing bracket 100c, the chip 100a, and the FPC substrate 100b is provided below the rivet head 121. The rivet head 121 is used to rivet the housing bracket 100c and the FPC substrate 100b.

[0066] The chip fixing device 12 of this embodiment is used to fix the chip 100a to the FPC substrate 100b. Specifically, the chip fixing device 12 also includes a fixing frame 123 disposed on the circular assembly line 51. A rivet head 121 is slidably mounted on the fixing frame 123 and connected to a driver, which drives the rivet head 121 up and down. A jig 122 is disposed below the rivet head 121 and is used to position the FPC substrate 100b and the housing bracket 100c. The FPC substrate 100b is provided with a plurality of rivet studs. The housing bracket 100c is made of metal and has a plurality of grooves corresponding to the rivet studs, through which the rivet studs pass. During riveting, the housing bracket 100c and the FPC 100 are assembled manually or by a robot and placed on the jig 122. The rivet head 121, driven by the driver, presses the rivet studs together. The rivet studs are deformed and pressed against the housing bracket 100c, thereby fixing the chip 100a to the FPC substrate 100b.

The oiling assembly 212 includes an oiling nozzle 2121. The oiling nozzle 2121 is used to move to the second assembly position under the drive of the third manipulator 211 and oil the slider 300c.

[0069] The oiling device 21 of this embodiment is used to apply oil to the slider 300c. During use of the vehicle air conditioning controller, the slider 300c and the middle box body 300a will experience relative motion. Therefore, lubricating oil is required to be applied to the contact surface between the slider 300c and the middle box body 300a to reduce wear on the slider 300c and the middle box body 300a. In this embodiment, the third manipulator 211 is a three-axis manipulator capable of movement in the X, Y, and Z axes. In the diagram, the X axis represents forward and backward movement, the Y axis represents left and right movement, and the Z axis represents up and down movement. The oiling assembly 212 is located on the Z axis, and the oiling nozzle 2121 is connected to an oil storage tank for storing lubricating oil. When the oiling device 21 is in operation, the oiling nozzle 2121, driven by the third manipulator 211, moves above the slider 300c and applies oil to the area of the slider 300c to be oiled. Optionally, the oiling nozzle 2121 is tilted at a certain angle to accommodate oiling of most positions of the slider 300c. Optionally, the oiling assembly 212 further includes a visual sensor disposed on one side of the oiling nozzle 2121 for detecting whether the lubricating oil is applied properly.
