Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a testing device for automotive air conditioning distribution boxes. Background Technology

[0002] The air distribution box of an automotive air conditioning system is a core component, primarily responsible for precisely distributing the cold and hot air generated by the air conditioner to different air vents within the vehicle, thereby controlling the airflow volume and direction. By adjusting the opening angle of the internal dampers, the distribution ratio of airflow to areas such as the driver's seat, front passenger seat, rear seats, or footwell is determined, thus meeting the personalized needs of passengers for airflow direction and volume.

[0003] like Figure 1 The image shows a car air distribution box structure. During the manufacturing process, it is necessary to monitor its appearance and whether any parts are missing. However, existing testing equipment has the following drawbacks: 1. The structural design of the testing section is not reasonable enough, and the design of the lighting structure for photographic testing is not reasonable enough, which affects the photographic testing. Furthermore, the testing is relatively simple, resulting in poor testing reliability. 2. During the testing process, the clamping and unloading are not continuous, and there is downtime in the testing section, resulting in low testing efficiency.

[0004] Therefore, how to design an automotive air conditioning distribution box testing device with a simpler and more reasonable structural design that can improve testing reliability and efficiency has become a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by this utility model is how to design an automotive air conditioning distribution box testing device with a simpler and more reasonable structural design that can improve testing efficiency and testing reliability.

[0006] To achieve the above objectives, this utility model provides an automotive air conditioning distribution box testing device, comprising a frame with two testing platforms arranged in pairs on the frame. Clamping fixtures are provided on the testing platforms for clamping the distribution box to be tested. A robotic arm is arranged between the two testing platforms on the frame at intervals. A camera and a 3D scanner are mounted on the operating end of the robotic arm via a mounting structure. The device is characterized in that: the mounting structure includes a vertically arranged mounting plate mounted on the operating end of the robotic arm; the camera is mounted on the lower outer side of the mounting plate; a ring-shaped lighting fixture is also mounted on the mounting plate, such that the lighting fixture is fitted under the camera; a horizontally outward-oriented support plate is also mounted on the upper outer side of the mounting plate; the 3D scanner is mounted below the far end of the support plate, and the 3D scanner has two 3D scanning heads inclined downwards and inwards.

[0007] Thus, the aforementioned automotive air conditioning distribution box testing equipment is equipped with two testing platforms. Each platform has clamps for holding the distribution boxes to be tested. During operation, while testing a distribution box on one platform, a previously tested distribution box can be removed from the other platform, and the next distribution box to be tested can be placed on it. This allows for more continuous testing and improves efficiency. Furthermore, it facilitates the installation of cameras and 3D scanners at the robotic arm's operating end, and the 3D scanner features two downward-facing, inward-angled scanning heads, enabling both photographic and scanning inspections, resulting in more reliable testing.

[0008] As an optimization, a support plate is installed on the upper outer side of the mounting plate, and two vertically downward connecting rods are installed on the support plate, with the lower ends of the connecting rods each connected to the upper surface of the lighting fixture.

[0009] By setting up connecting supports, it becomes easier to install lighting fixtures.

[0010] Furthermore, a connector is provided on the inner side of the mounting plate, and the far end of the connector is fixed to the operating end of the robotic arm.

[0011] Furthermore, triangular stabilizing blocks are arranged in pairs between the mounting plate and the support plate.

[0012] Furthermore, the support plate has two vertically arranged elongated holes in pairs, each containing a connecting screw, and the corresponding connection of the connecting screw is located in a threaded hole on the mounting plate.

[0013] As an optimization, two vertically arranged columns are arranged in pairs on the frame, a horizontally arranged platform plate is arranged above the columns, and a rotation drive motor is arranged below the platform plate. The working end of the rotation drive motor is connected to the turntable above the platform plate. The testing platform includes a horizontally arranged support plate installed above the turntable. A clamping fixture is provided on the support plate for clamping the air distribution box to be tested.

[0014] In this way, by setting up columns, platform plates, rotation drive motors and turntables, the air distribution box on the testing platform can be rotated more effectively, and the testing of various angles can be performed more effectively.

[0015] As an optimization, a first stabilizing link and a second stabilizing link are respectively installed between the lower ends and between the middle of the two columns.

[0016] In this way, by setting up a first stabilizing link and a second stabilizing link, the structural design becomes more stable.

[0017] As an optimization, the frame includes a support base on one side, on which the robotic arm is mounted.

[0018] In this way, by setting up a support base, it becomes easier to install the robotic arm.

[0019] As an optimization, the frame includes a conveyor frame on one side, on which a conveyor structure is provided for conveying pallets. The pallets are provided with a support structure for placing air distribution boxes. The conveyor structure can drive the pallets to move horizontally, placing the pallets at the loading and unloading stations at both ends and at the paired lifting stations in the middle. The frame includes a lifting bracket set on one side of the lifting station, on which a lifting mechanism is provided. The lifting mechanism has a clamping end and can clamp both ends of the pallet to drive the pallet to move vertically upward to the waiting station. The frame is also provided with a three-dimensional movement control structure, and the gripping mechanism at the operation execution end of the three-dimensional movement control structure can grip the air distribution boxes on the waiting station and place them on the clamping fixture.

[0020] In this way, during operation, the pallet containing the air distribution box is placed on the loading station at one end of the conveying structure. The conveying structure can move the pallet horizontally and then to the lifting station. The lifting mechanism on the lifting bracket has clamping ends that can clamp the two ends of the pallet, moving the pallet vertically upward to the waiting station. The gripping mechanism on the operating execution end of the three-dimensional movement control structure can grab the air distribution box on the waiting station and place it on the clamping fixture. After the inspection is completed, the gripping mechanism on the operating execution end of the three-dimensional movement control structure grabs the inspected air distribution box and places it on the pallet on the waiting station. The lifting mechanism then moves the pallet vertically downward and places it on the lifting station, and then it is conveyed to the unloading station at the other end. The entire structural design is simpler and more reasonable, which can better reduce waiting time and improve inspection efficiency.

[0021] As an optimization, the lifting mechanism includes a lifting mounting plate disposed inside the lifting bracket, and a vertical movement control mechanism disposed between the lifting mounting plate and the lifting bracket; two horizontally inwardly disposed lifting clamping plates are disposed at intervals on the lower inner side of the lifting mounting plate, and two lifting clamping cylinders are disposed at intervals on the lower surface of the lifting clamping plates, such that the piston rod end of the lifting clamping cylinder can extend inward and be inserted into the mounting holes of the lifting blocks on both sides of the tray.

[0022] This design makes the lifting mechanism simpler and more reasonable, and it can better clamp the pallet, making it more stable and reliable.

[0023] Furthermore, the vertical movement control mechanism uses a guide rail structure for vertical guidance and a cylinder for vertical drive.

[0024] As an optimization, the gripping mechanism includes a horizontally arranged mounting plate. A first clamping cylinder, vertically downwards, is mounted at one end of the mounting plate. The first clamping cylinder has two clamping rods, each with a clamping block mounted on it. A second clamping cylinder, horizontally arranged, is mounted at the other end of the mounting plate. Each of the second clamping cylinders has a cylinder rod at both ends and a vertically downwards clamping side plate mounted on it. A clamping block is mounted on the lower end of each clamping side plate. The two clamping blocks and the two clamping blocks can each form a clamping opening and clamp onto the air distribution box.

[0025] This design makes the gripping mechanism simpler and more reasonable, enabling it to grip the air distribution box more effectively and reliably.

[0026] Furthermore, the three-dimensional motion control structure includes a lateral motion control mechanism, a longitudinal motion control mechanism, and a vertical drive control mechanism; it uses an existing guide rail structure for guidance and a cylinder for drive.

[0027] Furthermore, the conveying structure can be a conveyor belt structure or a chain structure; both can be implemented using existing technologies.

[0028] In summary, the above-mentioned equipment features a simpler and more reasonable structural design, which improves detection reliability and efficiency. Attached Figure Description

The 3D scanner has two 3D scanning heads 10 tilted downwards and inwards.

[0040] Thus, the aforementioned automotive air conditioning distribution box testing equipment is equipped with two testing platforms. Each platform has clamps for holding the distribution boxes to be tested. During operation, while testing a distribution box on one platform, a previously tested distribution box can be removed from the other platform, and the next distribution box to be tested can be placed on it. This allows for more continuous testing and improves efficiency. Furthermore, it facilitates the installation of cameras and 3D scanners at the robotic arm's operating end, and the 3D scanner features two downward-facing, inward-angled scanning heads, enabling both photographic and scanning inspections, resulting in more reliable testing.

[0041] In this specific embodiment, a support plate 11 is installed on the upper outer side of the mounting plate, and two vertically downward connecting rods 12 are installed on the support plate, such that the lower ends of the connecting rods are each connected to the upper surface of the lighting fixture.

[0042] By setting up connecting supports, it becomes easier to install lighting fixtures.

[0043] Furthermore, a connector 13 is provided on the inner side of the mounting plate, and the far end of the connector is fixed to the operating end of the robotic arm.

[0044] Furthermore, triangular stabilizing blocks 14 are provided in pairs between the mounting plate and the support plate.

[0045] Furthermore, the support plate has two vertically arranged elongated holes in pairs, each containing a connecting screw, and the corresponding connection of the connecting screw is located in a threaded hole on the mounting plate.

The working end of the rotation drive motor is connected to the turntable 18 above the platform plate. The testing platform includes a horizontally arranged support plate 19 installed above the turntable.

The conveying structure can move the pallet horizontally and then to the lifting station. The lifting mechanism on the lifting bracket has clamping ends that can clamp the two ends of the pallet, moving the pallet vertically upward to the waiting station. The gripping mechanism on the operating execution end of the three-dimensional movement control structure can grab the air distribution box on the waiting station and place it on the clamping fixture. After the inspection is completed, the gripping mechanism on the operating execution end of the three-dimensional movement control structure grabs the inspected air distribution box and places it on the pallet on the waiting station.
