[0034] Example 1

[0035] This embodiment provides a detection device, such as Figure 1-7 As shown, the detection device includes a conveying component 1, a visual component 2 and a judgment component 3. The workpiece 4 to be inspected is located on the conveying component 1 and moves with the conveying component 1. The visual component 2 is located above the conveying component 1, and it can move and take an image of the workpiece 4 to be inspected. The judgment component 3 is communicatively connected with the visual component 2, and it can receive the image taken by the visual component 2, and compare the image with a preset standard image, and output whether the workpiece 4 to be inspected is qualified according to the comparison result.

[0036] Specifically, if Figure 1 As shown, the conveying assembly 1 includes a third bracket 11, a conveyor belt 12 and a driving member. The conveyor belt 12 is arranged on the third bracket 11, and the driving member is connected to the conveyor belt 12 to drive the conveyor belt 12 to rotate; after the workpiece 4 to be inspected is placed on the conveyor belt 12, the pneumatic driving member and the conveyor belt 12 can move with the workpiece 4 to be inspected.

[0037] In addition, the heights of the two ends of the third bracket 11 are different, so that the conveyor belt 12 has a slope. As for the transmission direction of the workpiece 4 to be inspected, whether it is from high to low or from low to high, this is related to the workpiece 4 to be inspected and is not specifically limited here.

[0038] The visual component 2 is located above the conveying component 1, and it can move and take images of the workpiece to be inspected 4. Since the visual component 2 can move, it can take images of the workpiece to be inspected 4 at multiple angles and multiple positions; for example, assuming that in a certain embodiment, the workpiece to be inspected 4 is a pre-installed component of the bottom shell of the air-conditioning indoor unit, then the visual component 2 needs to take pictures of the motor, the wind sweeping blades and the screw assembly position of the motor on the bottom shell to provide a basis for the subsequent work of the judgment component 3.

[0039] The judgment component 3 is used to compare the image captured by the visual component 2 with a preset standard image, and output whether the workpiece 4 to be inspected is qualified based on the comparison result. For example, the judgment component 3 is preset with standard images of various angles of the key parts of the workpiece 4 to be inspected. For example, when the workpiece to be inspected is a pre-assembled component of the bottom shell, the judgment component 3 has standard images of the motor, the wind sweeping blades, and the screw assembly positions of the motor. When making a judgment, the judgment component 3 compares the image captured by the visual component 2 with multiple pre-stored images one by one, selects the closest standard image, and then compares the key parts in the image. If there is a lot of overlap in the key parts, it is judged to be qualified, otherwise it is unqualified.

[0040] The detection device provided in this embodiment addresses the technical problems of visual fatigue caused by manual inspection, products with missing parts flowing into the next process, employees' monotonous and repetitive actions, high labor intensity and low production efficiency. It uses judgment components to ultimately achieve automatic detection, ensure the qualified rate of outgoing products, and at the same time improve production efficiency, production continuity and quality stability.

[0041] In a specific embodiment, Figures 1-4 As shown, the detection device further includes a defective product recovery component 5 , which is located downstream of the visual component 2 and is used to recover the defective workpiece 4 to be inspected.

[0042] When the judgment component 3 outputs that the workpiece to be inspected 4 is a qualified product, the workpiece to be inspected 4 continues to flow into the next process, and when the judgment component 3 outputs that the workpiece to be inspected 4 is an unqualified product, the workpiece to be inspected 4 is recycled by the unqualified product recycling component 5, realizing automatic sorting of unqualified products.

[0043] In a specific embodiment, Figure 1 As shown, the detection device also includes a first photoelectric sensing component 6, which is fixed on one side of the conveying component 1 and is used to sense whether the workpiece 4 to be inspected moves to the visual component 2 to determine whether the visual component 2 starts working.

[0044] The first photoelectric sensing component 6 includes a first photoelectric sensor, a device that converts light signals into electrical signals. Its operating principle is based on the photoelectric effect, which occurs when light strikes a substance and its electrons absorb the energy of photons, generating a corresponding electrical effect. In this embodiment, when the workpiece 4 to be inspected moves toward the visual component 2, the photoelectric sensor senses the workpiece 4 and transmits the sensing result to the judgment component 3, which then activates the visual component 2 to begin operation.

[0045] In a specific embodiment, Figure 1As shown, the detection device also includes a second photoelectric sensing component 7 for determining whether the defective product recovery component 5 starts working. The second photoelectric sensing component 7 is fixed on one side of the conveying component 1 and is located downstream of the first photoelectric sensing component 6.

[0046] The second photoelectric sensing assembly 7 also includes a second photoelectric sensor. When the judgment assembly 3 determines that the current workpiece 4 to be inspected is a defective product and the second photoelectric sensing assembly 7 senses the workpiece 4 to be inspected, it proves that the workpiece 4 to be inspected has been moved to the defective product recovery assembly 5. At this time, the defective product recovery assembly 5 is activated to sort the defective products.

[0047] In a specific embodiment, Figure 1 As shown, the visual component 2 includes a six-axis robot 21, a detection lens 22 and a first bracket 23. The six-axis robot 21 is fixed on the first bracket 23. The detection lens 22 is arranged at the end of the six-axis robot 21 and can move with the six-axis robot 21.

[0048] Specifically, if Figure 6 As shown, the six-axis robot 21 has multiple motors and axes internally, enabling it to move and rotate in various directions. The six axes of the six-axis robot 21 are: Axis 1: Base Axis; This is the robot's first axis, connecting the base and the second axis. Rotation of the Base Axis enables the robot to rotate in the horizontal plane. Axis 2: Shoulder Axis; This is the robot's second axis, connecting the first and third axes. Rotation of the Shoulder Axis enables the robot to rotate in the vertical plane. Axis 3: Elbow Axis; This is the robot's third axis, connecting the second and fourth axes. Rotation of the Elbow Axis enables the robot to bend in the vertical plane. Axis 4: Wrist Axis 1; This is the robot's fourth axis, connecting the third and fifth axes. Rotation of the Wrist Axis 1 enables the robot to rotate in the horizontal plane. Axis 5: Wrist Axis 2; This is the robot's fifth axis, connecting the fourth and sixth axes. Rotational movement along the wrist's two axes enables the robot to rotate in the vertical plane. Sixth Axis: Wrist Three-Axis; Wrist Three-Axis is the robot's sixth axis, connecting the fifth axis to the robot's end effector. Rotational movement along the wrist's three axes enables the robot to rotate in the horizontal plane.

[0049] Therefore, the six-axis robot 21 can drive the detection lens 22 to rotate in various directions, and then photograph the workpiece 4 to be inspected at various positions and angles; wherein the detection lens 22 is a camera.

[0050] In a specific embodiment, Figure 1As shown, the defective product recovery component 5 includes a grabbing unit 51, a slide 52, a placement platform 53 and a second bracket 54. The grabbing unit 51 and the slide 52 are both fixed on the second bracket 54, and the placement platform 53 is connected to the end of the slide 52; wherein, the grabbing unit 51 can work or not work according to the output structure of the judgment component 3.

[0051] Specifically, the slide 52 is arranged in parallel with the conveyor belt 12, and the slide 52 is arranged on one side of the conveyor belt 12, and the grabbing unit 51 is located above the conveyor belt 12. The second bracket 54 includes a slide bracket for fixing the slide 52 and a grabbing bracket for fixing the grabbing unit 51. The movable end of the grabbing unit 51 faces downward. When the current workpiece 4 to be inspected is a defective product, the grabbing unit 51 can move to the position of the workpiece 4 to be inspected, grab it, and place it on the slide 52. Then, it enters the placement platform 53 to sort the defective products.

[0052] In a specific embodiment, Figure 4 and Figure 5 As shown, the grasping unit 51 includes a frame 511, a first cylinder 512, a slide 513, a second cylinder 514 and a clamping module 515. The first cylinder 512 is arranged on the frame 511, the slide 513 is arranged on the first cylinder 512 and can move under the action of the first cylinder 512, the second cylinder 514 is connected to the slide 513, and the clamping module 515 is arranged at the end of the second cylinder 514 for clamping the unqualified workpiece 4 to be inspected.

[0053] Specifically, the first cylinder 512 can move horizontally, thereby driving the slide 513 to move horizontally; the second cylinder 514 can move up and down, thereby driving the clamping module 515 to move up and down; that is, under the action of the first cylinder 512, the slide 513 and the second cylinder 514, the clamping module 515 can move in four directions of up, down, left and right, and thus can adjust its distance from the workpiece 4 to be inspected, so that it can firmly grasp the tool to be inspected.

[0054] In a specific embodiment, Figure 4 As shown, the clamping module 515 includes a first clamping plate 5151, a first driving member 5152, a second clamping plate 5153 and a second driving member 5154. The first driving member 5152 is connected to the first clamping plate 5151, and the second driving member 5154 is connected to the second clamping plate 5153. The first driving member 5152 and the second driving member 5154 can respectively drive the first clamping plate 5151 and the second clamping plate 5153 to move towards or away from each other.

[0055] When it is necessary to grab the workpiece 4 to be inspected, the first driving member 5152 drives the first clamping plate 5151, and the second driving member 5154 drives the second clamping plate 5153 to move towards each other to achieve clamping; when it is necessary to place the workpiece 4 to be inspected on the slide 52, the first driving member 5152 drives the first clamping plate 5151, and the second driving member 5154 drives the second clamping plate 5153 to move away from each other to achieve the placement of the workpiece 4 to be inspected.

[0056] In a specific embodiment, the judgment component 3 includes a controller and a display for displaying the comparison results. The controller is respectively connected to the display, the first photoelectric sensing component 6, the second photoelectric sensing component 7, the unqualified product recovery component 5, and the visual component 2. The controller is pre-installed with a standard image corresponding to the workpiece 4 to be inspected. The display can show whether the current workpiece 4 to be inspected is qualified, making it convenient for personnel to understand the workpiece 4 to be inspected at any time.

[0057] In one embodiment, Figure 8 As shown, the workpiece 4 to be inspected is a pre-assembled bottom shell component of an air conditioner inner unit.

[0058] like Figure 9 As shown, the specific working process of the detection device provided in this embodiment is as follows:

[0059] The pre-assembled bottom shell components of the air conditioner are placed on the conveyor belt 12, the driving part is started, and the conveyor belt 12 begins to drive the bottom shell components of the air conditioner to flow; when the bottom shell components of the air conditioner flow to the first photoelectric sensor, the first photoelectric sensor transmits a signal to the controller, the controller controls the visual component 2 to work, and the six-axis robot 21 drives the detection lens 22 to capture at various positions and angles, and transmits the shooting results to the controller; after receiving the shooting results, the controller compares, analyzes and judges them with the preset standard diagram, and displays the judgment results on the display; at the same time, when the judgment result is unqualified, and the second photoelectric sensor senses the workpiece 4 to be inspected, the controller controls the unqualified product recovery component 5 to work, and under the action of the first cylinder 512, the slide 513 and the second cylinder 514, the clamping module 515 grabs the workpiece 4 to be inspected, and recovers it on the placement platform 53 through the slide 513; when it is a qualified product, it continues to be transported on the conveyor belt 12 until it enters the next process.
