[0029] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0030] The following is for reference. Figures 1-2 Description of appearance defect detection device 1 according to an embodiment of the present utility model.

[0031] According to the embodiment of the present utility model, the appearance defect detection device 1, such as Figure 1 and Figure 2 As shown, the appearance defect detection equipment 1 may include: a frame 10, a conveying mechanism 20, a driving mechanism 30, and a detection mechanism 40. The frame 10 has a detection station. The conveying mechanism 20 has a support member 21 for placing the part to be detected 2. The conveying mechanism 20 is used to convey the support member 21 along a first direction. The driving mechanism 30 is located on the frame 10 and is used to drive the support member 21 to rise and / or rotate. The detection mechanism 40 is located on the detection station and fixed to the frame 10. The detection mechanism 40 is used to detect whether the part to be detected 2 has appearance defects.

[0032] It should be noted that in the relevant technologies, the existing method of detecting appearance defects in air conditioning compressors is manual inspection. Manual inspection is prone to missed detections, which affects the production yield and is time-consuming and labor-intensive.

[0033] Based on this, this application provides an appearance defect detection device 1. The frame 10 has a detection station where the component 2 to be detected can be inspected. The conveying mechanism 20 can be configured as a belt conveyor, chain conveyor, or other conveying device capable of conveying the component 2 to be detected. The conveying mechanism 20 can pass through the frame 10 along a first direction. The conveying mechanism 20 has a support member 21 for placing the component 2 to be detected. The conveying mechanism 20 can convey the support member 21 along the first direction. The conveying mechanism 20 can convey the support member 21 to the detection station, or it can move the support member 21 away from the detection station to a subsequent station. When the appearance defect detection device 1... Figure 1 When placing the object in a specific direction, the first direction is... Figure 1The Y-axis is shown in the diagram. The drive mechanism 30 can be mounted on the frame 10 via snap-fit, bolt connection, or other means. The drive mechanism 30 can drive the support member 21 to rise or fall, or drive the support member 21 to rotate, or drive both rising and falling and rotating. This application uses the example of the drive mechanism 30 driving both rising and falling and rotating the support member 21 for illustration. The inspection mechanism 40 is located at the inspection station. The inspection mechanism 40 can be fixedly connected to the frame 10 via welding, bolt connection, or other means. The inspection mechanism 40 is used to inspect whether the part 2 to be inspected has any appearance defects.

[0034] In this embodiment, the conveying mechanism 20 conveys the support member 21 on which the component to be tested 2 is placed. When the support member 21 is at the testing station, the driving mechanism 30 drives the support member 21 to rise, and the support member 21 lifts the component to be tested 2 together. When the component to be tested 2 can be tested by the testing mechanism 40, the driving mechanism 30 drives the support member 21 to rotate with the component to be tested 2. The testing mechanism 40 detects whether the component to be tested 2 has appearance defects, thereby achieving the effect of automatically detecting whether the component to be tested 2 has appearance defects, which can improve testing efficiency, increase testing accuracy, and reduce labor costs.

[0035] In some embodiments of this utility model, such as Figure 1 As shown, the detection mechanism 40 may include a first detection part 41 and a second detection part 42. Both the first detection part 41 and the second detection part 42 are fixed on the frame 10, and the first detection part 41 and the second detection part 42 are respectively arranged on opposite sides of the conveying mechanism 20 along the second direction, which is perpendicular to the first direction.

[0036] The first inspection unit 41 can be fixed to the frame 10 by welding, bolting, or other methods, and the second inspection unit 42 can also be fixed to the frame 10 by welding, bolting, or other methods. The first inspection unit 41 and the second inspection unit 42 are arranged opposite to each other and spaced apart along a second direction. The first inspection unit 41 and the second inspection unit 42 are located on opposite sides of the conveying mechanism 20, respectively. When the appearance defect inspection equipment 1... Figure 1 When setting the direction, the second direction is Figure 1 In the X direction, the first direction and the second direction are perpendicular.

[0037] As an example, the first detection unit 41 may include a first detection bracket and a first detection instrument. The first detection instrument may be a camera. The first detection bracket supports the first detection instrument and can be bolted to the first detection instrument. The first detection bracket can be fixed to the frame 10 by bolting. The second detection unit 42 may include a second detection bracket and a second detection instrument. The second detection instrument may be a camera. The second detection bracket supports the second detection instrument and can be bolted to the second detection instrument. The second detection bracket can be fixed to the frame 10 by bolting.

[0038] Both the first and second inspection instruments are used to detect whether the component 2 under inspection has any appearance defects. Both instruments are located at the inspection station. When the component 2 is at the inspection station, the drive mechanism 30 drives the support member 21 to rise, and the support member 21 lifts the component 2 along with it. When the component 2 is between the first and second inspection instruments, the drive mechanism 30 drives the support member 21 to rotate, and the support member 21 rotates one full turn with the component 2. Simultaneously, both the first and second inspection instruments take pictures of the component 2 under inspection. The first and second inspection instruments detect whether the component 2 has any appearance defects. By setting up the first inspection unit 41 and the second inspection unit 42, the inspection efficiency and accuracy of the component 2 under inspection can be improved.

[0039] In some embodiments of this utility model, the first and second detection instruments can be staggered along the height direction of the appearance defect detection device 1, that is, the setting height of the first and second detection instruments is different. When the appearance defect detection device 1 is as follows... Figure 1 When setting the orientation, the height orientation of the appearance defect detection device 1 is as follows: Figure 1 In the Z-direction, the height direction of the appearance defect detection device 1 is perpendicular to both the first and second directions. The first detection instrument can be used to detect the upper half of the component 2 to be inspected, and the second detection instrument can be used to detect the lower half of the component 2 to be inspected, which allows the detection mechanism 40 to perform more comprehensive inspections and also improves detection efficiency.

[0040] In some embodiments of this utility model, the drive mechanism 30 may include: a fixed part 31, a lifting drive part 32, and a rotating drive part 33. The fixed part 31 is fixed to the frame 10 and located below the conveying mechanism 20. The lifting drive part 32 is fixed to the fixed part 31 and connected to the rotating drive part 33. The lifting drive part 32 is used to drive the rotating drive part 33 to lift and lower. The rotating drive part 33 is located above the fixed part 31 and is suitable for cooperating with the support member 21 to drive the support member 21 to rotate.

[0041] The fixing part 31 can be constructed as a plate-like structure. The fixing part 31 can be fixedly connected to the frame 10 by welding, bolting, or other methods. The fixing part 31 is located below the conveying mechanism 20. The lifting drive part 32 can be fixed to the fixing part 31 by snap-fitting, bolting, or other methods. The fixing part 31 can be used to fix the lifting drive part 32. The lifting drive part 32 can be connected to the rotary drive part 33 by snap-fitting, bolting, or other methods. The lifting drive part 32 can drive the rotary drive part 33 to move up and down. As an example, the lifting drive part 32 can include a controller and a push cylinder. The push shaft of the push cylinder is connected to the rotary drive part 33. When the controller controls the push shaft of the push cylinder to extend, the push shaft can drive the rotary drive part 33 to rise. When the controller controls the push shaft of the push cylinder to retract, the push shaft can drive the rotary drive part 33 to descend.

[0042] The rotary drive unit 33 is located above the fixed part 31. The rotary drive unit 33 can move up and down above the fixed part 31, thus avoiding collisions with the fixed part 31 during its ascent and improving operational safety. The rotary drive unit 33 can be assembled with the support member 21. The rotary drive unit 33 can be connected to the support member 21 via snap-fit, magnetic connection, or other methods, and can drive the support member 21 to rotate.

[0043] As an example, the lifting drive unit 32 can be located below the fixed part 31, and the rotating drive unit 33 can be located above the fixed part 31. The fixed part 31 is located between the lifting drive unit 32 and the rotating drive unit 33. The rotating drive unit 33 can fall to the fixed part 31 and abut against it. A first clearance hole 311 can be formed on the fixed part 31. The push shaft in the lifting drive unit 32 can pass through the first clearance hole 311. The push shaft can move relative to the fixed part 31 along the height direction of the appearance defect detection device 1 to drive the rotating drive unit 33 to rise and fall. This makes the structure of the drive mechanism 30 more compact and reduces the space occupied by the drive mechanism 30.

[0044] In some embodiments of this utility model, the rotary drive unit 33 may include: a mounting plate 331, a rotating plate 332, and a rotary drive member 333. The mounting plate 331 is connected to the lifting drive unit 32, the rotary drive member 333 is fixedly mounted on the mounting plate 331, the rotating plate 332 is located above the mounting plate 331 and is connected to the rotary drive member 333, the rotary drive member 333 is used to drive the rotating plate 332 to rotate, and the rotating plate 332 is adapted to cooperate with the support member 21 to drive the support member 21 to rotate.

[0045] Mounting plate 331 can be connected to lifting drive unit 32 by means of snap-fit, bolt connection or other means. Rotation drive unit 33 can be connected to lifting drive unit 32 by mounting plate 331. Mounting plate 331 is located above fixed part 31. Mounting plate 331 can move relative to fixed part 31 along the height direction of appearance defect detection equipment 1.

[0046] As an example, the mounting plate 331 can be fixedly connected to the push cylinder in the lifting drive unit 32, and the push cylinder drives the mounting plate 331 to move along the height direction of the appearance defect detection device 1. Along the circumference of the mounting plate 331, a plurality of guide posts 3311 can be formed on the side of the mounting plate 331 near the fixing part 31, and a plurality of second clearance holes can be formed on the fixing part 31. Each second clearance hole penetrates the fixing part 31 along the height direction of the appearance defect detection device 1, and the plurality of guide posts 3311 can pass through the plurality of second clearance holes. Each guide post 3311 has a corresponding second clearance hole. Each guide post 3311 has a limiting block 3312 formed at the end opposite to the mounting plate 331. The limiting block 3312 can abut against the side of the fixing part 31 opposite to the mounting plate 331, thereby limiting the movement distance of the mounting plate 331 along the height direction of the appearance defect detection device 1. When the mounting plate 331 moves relative to the fixing part 31, it prevents the mounting plate 331 and the fixing part 31 from separating, which helps to improve the safety of the mounting plate 331 when it is raised or lowered, thereby improving the safety of the rotary drive part 33 during operation. Each guide post 3311 can also be fitted with a linear bearing 3313. The linear bearing 3313 can make the guide post 3311 move linearly along the height direction of the appearance defect detection device 1, which helps to improve the stability of the movement of the mounting plate 331.

[0047] The rotary drive component 333 can be fixed to the mounting plate 331 by means of snap-fit, bolt connection, etc. The rotating plate 332 is located above the mounting plate 331 along the height direction of the appearance defect detection equipment 1. The rotary drive component 333 can be located between the rotating plate 332 and the mounting plate 331. The rotating plate 332 can be connected to the rotary drive component 333 for transmission. The rotating plate 332 can be connected to the mounting plate 331 through the rotary drive component 333. The rotary drive component 333 can drive the rotating plate 332 to rotate, thereby achieving the effect that after the mounting plate 331 drives the rotating plate 332 to rise together, the rotary drive component 333 drives the rotating plate 332 to rotate.

[0048] The rotary drive component 333 can be configured as a rotary drive motor, and the housing of the rotary drive motor can be fixedly connected to the mounting plate 331. As an example, the motor shaft of the rotary drive motor can extend along the height direction of the appearance defect detection device 1. A drive shaft is formed on the side of the rotating plate 332 near the mounting plate 331, extending along the height direction of the appearance defect detection device 1. The drive shaft can be connected to the motor shaft of the rotary drive motor via a coupling, thereby enabling the motor shaft to rotate, driving the drive shaft to rotate, and the rotation of the drive shaft to drive the rotating plate 332 to rotate together. As another example, the motor shaft of the rotary drive motor can extend along a second direction. A drive gear is formed on the side of the rotating plate 332 near the mounting plate 331, with the axis of the drive gear parallel to the height direction of the appearance defect detection device 1. The motor shaft of the rotary drive motor can mesh with the drive gear. The rotation of the motor shaft of the rotary drive motor drives the drive gear to rotate, and the drive gear and drive shaft rotate together, thereby driving the rotating plate 332 to rotate together.

[0049] When the rotating plate 332 rises to abut against the support member 21, the rotating plate 332 can be assembled with the support member 21. The rotating plate 332 can continue to rise, thereby driving the support member 21 to rise together. When the rotating plate 332 rotates, the rotating plate 332 can drive the support member 21 to rotate together, thereby achieving the effect of the component to be tested 2 rotating between the first detection part 41 and the second detection part 42.

[0050] In some embodiments of this utility model, the rotating plate 332 is provided with a first positioning part 3321, and the support member 21 is provided with a second positioning part. The first positioning part 3321 is adapted to be positioned and cooperated with the second positioning part.

[0051] The first positioning part 3321 can be one of a positioning post and a positioning notch, and the second positioning part can be the other of a positioning post and a positioning notch. The positioning post is assembled into the positioning notch, and the positioning post and the inner wall of the positioning notch are mutually restrained and abutted, thereby realizing the positioning cooperation between the first positioning part 3321 and the second positioning part, and preventing relative rotation between the rotating plate 332 and the support member 21. However, the present invention is not limited to this. The first positioning part 3321 and the second positioning part can both be magnetic components, and the first positioning part 3321 and the second positioning part can be magnetically attracted to each other, thereby preventing mutual rotation between the rotating plate 332 and the support member 21, which is beneficial to improving the safety of the appearance defect detection equipment 1 during operation.

[0052] In some embodiments of this utility model, the appearance defect detection device 1 may further include: a limiting mechanism 50, which is disposed on the driving mechanism 30 and is liftable. When the support member 21 moves to the detection station along the first direction, the limiting mechanism 50 is adapted to cooperate with the support member 21 to limit the movement of the support member 21 along the first direction.

[0053] The limiting mechanism 50 can be fixed to the fixed part 31 by welding, bolt connection, or other means, thereby placing the limiting mechanism 50 on the drive mechanism 30. The limiting mechanism 50 can move up and down along the height direction of the appearance defect inspection equipment 1. When the limiting mechanism 50 is not working, it is located below the conveying mechanism 20. When the support member 21 moves to the inspection station along the first direction, the limiting mechanism 50 can rise and cooperate with the support member 21 to limit its movement. The limiting mechanism 50 can restrict the support member 21 from continuing to move along the first direction, thus limiting the support member 21 to the inspection station. The support member 21 can then complete the subsequent inspection of the component 2 to be inspected at the inspection station. When the support member 21 is about to leave the inspection station, the limiting mechanism 50 descends and separates from the support member 21, allowing the support member 21 to continue moving along the first direction.

[0054] In some embodiments of this utility model, such as Figure 2 As shown, the limiting mechanism 50 may include: a first limiting part 51 and a second limiting part 52. The first limiting part 51 and the second limiting part 52 are opposite to each other and spaced apart along a first direction. Both the first limiting part 51 and the second limiting part 52 can be raised and lowered. When the support member 21 moves to the detection station, both the first limiting part 51 and the second limiting part 52 are adapted to cooperate with the support member 21 for limiting.

[0055] The first limiting part 51 and the second limiting part 52 are arranged opposite to each other and spaced apart along the first direction. The first limiting part 51 and the second limiting part 52 can be provided at both ends of the fixing part 31 along the first direction. Both the first limiting part 51 and the second limiting part 52 can be raised and lowered. When the support member 21 moves to the inspection station, the first limiting part 51 rises and the second limiting part 52 rises. Both the first limiting part 51 and the second limiting part 52 abut against the support member 21, thereby achieving a limiting engagement with the support member 21. As an example, both the first limiting part 51 and the second limiting part 52 can be constructed as electric telescopic rods. When the support member 21 moves to the inspection station, the electric telescopic rods can extend and abut against the support member 21 for limiting. When the support member 21 is about to leave the inspection station, the electric telescopic rods retract. As another example, both the first limiting part 51 and the second limiting part 52 can be configured as a push cylinder. When the support member 21 moves to the detection station, the piston rod of the push cylinder can extend and abut against the support member 21 for limitation. When the support member 21 is about to leave the detection station, the piston rod of the push cylinder retracts.

[0056] In some embodiments of the present invention, the limiting mechanism 50 may further include: a first driving member 53 and a second driving member 54, the first driving member 53 and the second driving member 54 being connected to the first limiting part 51 and the second limiting part 52 respectively, the first driving member 53 being used to drive the first limiting part 51 to rise and fall, and the second driving member 54 being used to drive the second limiting part 52 to rise and fall.

[0057] The first driving member 53 can be connected to the first limiting part 51, and the first driving member 53 can drive the first limiting part 51 to rise and fall. As an example, when the first limiting part 51 is configured as an electric telescopic rod, the first driving member 53 can be configured as a first drive motor, and the first driving member 53 can be electrically connected to the first limiting part 51, and the first drive motor can drive the corresponding electric telescopic rod to rise and fall. As another example, when the first limiting part 51 is configured as a push cylinder, the first driving member 53 can be configured as a first controller, and the first driving member 53 can be communicatively connected to the first limiting part 51, and the first controller can control the piston rod of the corresponding push cylinder to extend or retract.

[0058] The second drive member 54 can be connected to the second limiting part 52, and the second drive member 54 can drive the second limiting part 52 to rise and fall. As an example, when the second limiting part 52 is configured as an electric telescopic rod, the second drive member 54 can be configured as a second drive motor, and the second drive member 54 can be electrically connected to the second limiting part 52, and the second drive motor can drive the corresponding electric telescopic rod to rise and fall. As another example, when the second limiting part 52 is configured as a push cylinder, the second drive member 54 can be configured as a second controller, and the second drive member 54 can be communicatively connected to the second limiting part 52, and the second controller can control the piston rod of the corresponding push cylinder to extend or retract.

[0059] In some embodiments of the present invention, the appearance defect detection device 1 may further include: a first sensor 60, the first sensor 60 being used to detect the position information of the support member 21, and the appearance defect detection device 1 being configured to control the limit mechanism 50 to rise according to the detection information of the first sensor 60.

[0060] The first sensor 60 can detect the position information of the support member 21. The first sensor 60 can be mounted on the drive mechanism 30 and can be fixedly connected to the fixing part 31 by means of snap-fit, bolt connection, etc. The first sensor 60 can be located at one end of the fixing part 31 along the first direction. When the support member 21 is transported to the inspection station by the conveying mechanism 20, the support member 21 first passes the first sensor 60 and then moves to the inspection station. The appearance defect detection device 1 can control the limit mechanism 50 to rise according to the detection information of the first sensor 60. As an example, the first sensor 60 can be constructed as a fiber optic sensor. When the support member 21 passes the first sensor 60, the detection signal of the first sensor 60 changes from zero to positive and then back to zero. The appearance defect detection device 1 can determine that the support member 21 has moved to the inspection station according to the change in the detection signal of the first sensor 60, and the appearance defect detection device 1 controls the limit mechanism 50 to rise.

[0061] In some embodiments of the present invention, the appearance defect detection device 1 further includes a second sensor 70, which is used to detect the position information of the support member 21. The appearance defect detection device 1 is configured to control the drive mechanism 30 to drive the support member 21 to rise according to the detection information of the second sensor 70.

[0062] The second sensor 70 can detect the position information of the support member 21. The second sensor 70 can be mounted on the drive mechanism 30 and can be fixedly connected to the fixing part 31 by means of snap-fit, bolt connection, etc. The second sensor 70 can be located at the other end of the fixing part 31 along the first direction. When the support member 21 moves to the detection station, the support member 21 can be located above the second sensor 70. The appearance defect detection device 1 can control the drive mechanism 30 to drive the support member 21 to rise based on the detection information of the second sensor 70. As an example, the second sensor 70 can be constructed as a fiber optic sensor. When the support member 21 moves to the detection station, the detection signal of the second sensor 70 changes from zero to one. The appearance defect detection device 1 can determine that the support member 21 has moved to the detection station and is fixed at the detection station based on the change in the detection signal of the second sensor 70. The appearance defect detection device 1 controls the drive mechanism 30 to drive the support member 21 to rise.

[0063] In some embodiments of this utility model, when the detection mechanism 40 detects that the component 2 to be detected does not have any appearance defects, the appearance defect detection device 1 is configured to lower the limiting mechanism 50 and drive the support member 21 to lower the driving mechanism 30.

[0064] When the inspection mechanism 40 detects that the part to be inspected 2 does not have any appearance defects, the appearance defect inspection equipment 1 controls the limiting mechanism 50 to descend, the lifting drive unit 32 drives the rotating drive unit 33 to descend, the rotating plate 332 and the support member 21 descend together. When the support member 21 lands on the conveying mechanism 20, the support member 21 and the rotating plate 332 separate, and the rotating drive unit 33 continues to fall to the initial position (the initial position is the position when the rotating drive unit 33 has not risen). At the same time, since the limiting mechanism 50 has descended, the limiting mechanism 50 no longer limits the support member 21. The conveying mechanism 20 conveys the support member 21 and moves the inspected part along the first direction to the subsequent station, realizing the automated inspection of whether the appearance defect inspection equipment 1 has appearance defects in the part to be inspected 2.

[0065] In some embodiments of this utility model, the top of the frame 10 may also be provided with an indicator light 80. When the testing mechanism detects that the part 2 to be tested has an appearance defect, the indicator light 80 can turn red and emit a beeping sound to prompt the staff to remove the tested part with the appearance defect.
