[0093] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0094] like Figures 1-25 As shown, this utility model provides an automatic assembly device for the evaporator corner bracket of an air conditioner indoor unit, realizing the automatic assembly of the evaporator corner bracket. Specifically, the automatic assembly device includes a body 300, a first positioning component 1, a sorting component 2, a second positioning component 3, and a feeding component 4; wherein:

[0095] The first positioning component 1 is installed on the body 300 and is used to support and position the first assembly component; in this embodiment, the first assembly component is the evaporator 100.

[0096] The second positioning component 3 is disposed beside the first positioning component 1 and is used to support and position the second assembly component; in this embodiment, the second assembly component is an angle bracket 200, which is used to be installed at one end of the evaporator 100.

[0097] The sorting component 2 is set next to the second positioning component 3 to adjust the orientation of the second assembly component; the sorting component 2 enables the vibration screening of the angle frame 200, completes the positioning of the front and back sides, and facilitates the clamping of the angle frame 200.

[0098] The feeding components 4 are respectively arranged on the side of the sorting component 2 and the second positioning component 3, so as to respectively complete the removal of the second assembly component from the sorting component 2 and the placement into the second positioning component 3, and the removal of the positioned second assembly component from the second positioning component 3 and the assembly with the first assembly component located in the first positioning component 1.

[0099] It should be noted that the feeding component 4 is not fully shown in the accompanying drawings of the instruction manual. Some drawings only show one feeding component 4, while the other is omitted to make it easier to see the other structures of the assembly device.

[0100] In this embodiment, as Figures 1-24 As shown, the sorting component 2 includes a vibratory feeder 21, a track chain 22, a conveyor line 23, and a vision camera 24; wherein:

[0101] The track 22 is set at an angle upward, with one end set inside the vibratory feeder 21 and the other end suspended in the air;

[0102] The conveyor line 23 is located below the track 22 to receive the second assembly component that falls from the top of the track 22;

[0105] Based on the structural characteristics of the angled frame's front and back sides, this invention allows the angled frame facing the chain track 22 to be transported upwards by gravity, driven by the chain drive. The angled frame facing backwards cannot adhere to the chain track 22 and falls back to the bottom of the vibrating plate 21. This achieves the function of identifying and transporting the angled frame's front and back sides. After reaching the top, it slides down onto the conveyor line 23, which then moves forward to the identification position of the vision camera 24. The vision camera 24, based on the characteristics of the angled frame, can then identify, locate, and filter the angled frame based on its front and back sides.

[0106] In this embodiment, the second positioning component 3 includes a positioning base 31, a second positioning electric cylinder 32, a positioning enclosure plate 33, a second lifting cylinder 34, a positioning push rod 35, and a roller 36; wherein:

One of the second positioning electric cylinders 32 is connected to a positioning push rod 35, while the other second positioning electric cylinder 32 is connected to two positioning push rods 35. The reason for this arrangement is that the corresponding position of the angle frame 200 is an arc-shaped structure. The two second positioning push rods 35 can push and guide the angle frame 200 to rotate into place, thereby achieving a precise positioning function.

[0114] As a further improvement of this utility model, the first positioning component 1 includes a placement base 11, a large plate angle positioning mechanism 12, a Z-axis positioning mechanism 13, a small plate angle positioning mechanism 14, an X-axis positioning mechanism 15, and a Y-axis positioning mechanism 16; wherein: the placement base 11 is used to support the first assembly component; the large plate angle positioning mechanism 12 and the small plate angle positioning mechanism 14 are arranged opposite each other on both sides of one end of the placement base 11 to clamp the small plate and large plate of the first assembly component for angle positioning; the Z-axis positioning mechanism 13 is arranged on the top of the placement base 11 for Z-axis positioning of the first assembly component; the X-axis positioning mechanism 15 is arranged on the other end of the placement base 11 for X-axis positioning of the first assembly component; and the Y-axis positioning mechanism 16 is arranged beside the Z-axis positioning mechanism 13 for Y-axis positioning of the first assembly component.

The positioning top plate 152 prevents the evaporator from dislodging from its positioning point due to line vibration when it reaches the workstation, thus correcting its position. These five mechanisms provide comprehensive evaporator positioning, preventing workpiece displacement.

[0145] This invention uses a multi-cylinder positioning mechanism to position the evaporator, which is placed flat on the tooling plate, according to its splicing angle and spatial position.

[0157] The automatic assembly device of this utility model can realize the automatic assembly production of evaporators and corner brackets. It can be applied to the assembly needs of more than twenty types of evaporator corner brackets, and can complete the all-round fixation of evaporators and corner brackets. It can achieve precise assembly of different types of evaporators, with stable assembly quality and greatly reduce labor intensity.

[0158] The process flow is as follows:

[0159] Based on the evaporator 100 and angle bracket 200 parameters entered into the information system, the evaporator 100, after being processed in the previous process, is conveyed to the first positioning component 1. Positioning grippers 145, pressure plates 133, pressure plates 165, positioning top plates 152, and positioning pressure plates 161, controlled by multiple external cylinders, achieve spatial angle and dimensional parameter positioning of the evaporator, as well as angle limitation on the main plate, side plates, and bending angles of the evaporator, completing the positioning of the evaporator's flared end. The angle bracket 200, after being processed in the previous process, falls into the vibratory feeder 21 through the feed inlet at the top of the vibratory feeder 21. The vibratory feeder 21 screens and adjusts the direction of the angle bracket 200, distinguishing between the front and back sides, and then it is conveyed by the conveyor line 23 to the position of the vision camera 24 for orientation. After the angled frame 200 is separated from the other side, the robot 41 picks it up and places it into the second positioning component 3. The positioning base 31 supports it, and the positioning plate 33 and rollers 36 complete the precise contour positioning. After positioning, the robot 41 senses that it has reached the gripping position, releases the rollers 36, and the robot 41 begins to work. It uses the suction cup 423 in the suction cup fixture 42 to pick up the plane in the groove of the angled frame, and uses the pressing plate 426 to press the angled frame 200. Then the robot 41 moves to the assembly position. According to the data entered by the system, the robot 41 extends forward and aligns the groove of the angled frame 200 with the bottom of the evaporator 100U for assembly. During the docking process, the angled frame buckle and the U tube are locked together, completing the automatic assembly process.

[0160] Specifically, such as Figure 25 As shown, after the angle bracket and evaporator have completed the previous processing steps, the second lifting cylinder in the second positioning component 3 rises, raising the positioning base. The angle bracket enters the vibratory feeder for material placement and completes the forward and reverse adjustment. Then, the robot picks it up and sends it into the second positioning component 3 to complete the positioning of the angle bracket. While the angle bracket is being positioned, the evaporator is sent into the first positioning component for full constraint positioning. Afterward, the robot picks up the positioned angle bracket and moves it to the assembly position to complete the assembly of the angle bracket and evaporator. After all processing is completed, the second lifting cylinder in the second positioning component 3 descends, thereby lowering the positioning base back to its original position.

[0161] It should be noted that in this utility model, guide structures can be set on both sides of all electric cylinders and pneumatic cylinders, and guide rail sliders are used to achieve stability during extension and retraction; both robots 41 are equipped with suction cup fixtures 42; in addition, in this utility model, in order to realize the connection, installation, relative movement between related components, the necessary fixing parts and support parts are set according to the actual situation, which will not be described in detail here; all grippers, pressure plates, top plates and other parts that come into contact with the workpiece can be equipped with buffer parts and silicone layers to reduce the damage to the workpiece caused by excessive pushing force during pushing, clamping or moving.
