Description

Technical Field

[0001] The present invention relates to the technical field of earphone appearance detection, and in particular to an earphone shell defect detection device. Background Art

[0002] Appearance inspection is mainly used to quickly identify the appearance defects of samples. The appearance inspection system is mainly used to quickly identify the appearance defects of samples, such as pits, cracks, warping, gaps, stains, sand, burrs, bubbles, uneven colors, etc. The inspected samples can be transparent or opaque.

[0003] In the earphone production process, one of the important links is the defect detection of the earphone shell. When the earphone shell is currently inspected for defects, it is difficult to rely on settings to detect the earphone shell due to the irregular shape of the earphone, so manual inspection is often used. The inspection method is to manually pick up the earphone and place it under the inspection light, and observe and inspect it by rotating the earphone with the human eye. This inspection method has a high error rate, and the earphone cannot be rotated at a uniform speed when it is manually picked up and rotated, so there is a certain probability of missing inspection in some parts of the earphone. In addition, long-term shell inspection under strong light can easily cause visual fatigue of the inspectors. The inspection efficiency and accuracy will decrease as the inspection time increases. Therefore, there is a lack of equipment for efficient detection of earphone shell defects.

[0004] Based on this, a device for detecting defects of earphone shell is proposed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-5 , the present invention provides a technical solution: A device for detecting defects in earphone shells comprises a fixed cylinder 1, a fixed plate 2 is connected to the outside of the fixed cylinder 1, a rotating seat 3 is connected to one end of the fixed plate 2, the fixed cylinder 1 and the rotating seat 3 are fixedly connected by the fixed plate 2, a motor 4 is connected inside the fixed cylinder 1, an active column 25 is connected to the output end of the motor 4, a turntable 5 is connected to the upper end of the active column 25, the active column 25 can be driven to rotate by the motor 4, a detection camera 6 is connected to the upper end of the turntable 5, the detection camera 6 detects the earphone shell with a high-precision camera, and when a defect occurs, an alarm signal is sent out by the detection camera 6 to provide an alarm signal. It is indicated that the headset has defects, and the inspector needs to take off the headset for manual endpoint screening. The detection camera 6 is a direct reference to the prior art and will not be described in detail here. The upper end of the fixing plate 2 is connected to a connecting column 19, and the upper end of the connecting column 19 is connected to a limiting plate 7. A deflection tube 10 is connected above the limiting plate 7. A deflection rod 11 is rotatably connected to the deflection tube 10. The deflection rod 11 is structurally limited by the deflection tube 10. A detection tube 12 is connected to one end of the deflection rod 11, and the detection tube 12 is made of transparent plastic material, which is convenient for the detection camera 6 to detect the outer shell of the headset fixed position; A driven column 23 is rotatably connected to the rotating seat 3, and a transmission belt 8 is connected between the driven column 23 and the active column 25. The driven column 23 and the active column 25 can be kept rotating synchronously through the transmission belt 8. A disk 13 is connected to the upper end of the driven column 23, and a rack 14 is connected to the disk 13. The rack 14 has an arc-shaped structure and can mesh with the flip gear 16, thereby driving the flip gear 16 to rotate. A flip mechanism is connected to one side of the detection tube 12 to cooperate with the rack 14 to rotate the earphone during the detection process.

[0020] Specifically, Figure 1 As shown, a limit clamp 9 is connected to the outer side of the limit plate 7, and the deflection tube 10 is connected to the upper end of the limit clamp 9 through a rod. By setting the limit clamp 9 structure, the limit clamp 9 can be used to limit and guide the turntable 5, so that the rotation of the turntable 5 structure is more stable, which will correspondingly improve the accuracy of the detection camera 6 in detecting the earphone shell.

[0021] Specifically, Figure 4 As shown, an anti-slip strip 26 is connected to the inner side of the detection tube 12. The anti-slip strip 26 is evenly connected to the inner wall of the detection tube 12. The anti-slip strip 26 is made of transparent rubber material, which can well protect the earphone shell and will not interfere with the detection of the earphone shell. There are multiple anti-slip strips 26, and multiple anti-slip strips 26 are evenly connected to the inner wall of the detection tube 12. The anti-slip strip 26 structure can prevent the earphone from popping out after the detection is completed, and play a certain limiting role on the earphone.

[0022] Specifically, Figure 4 and Figure 5As shown, the flip mechanism includes a fixed frame 28, one side of the fixed frame 28 is connected to a check block 32, one side of the check block 32 is provided with an inclined surface, which is convenient for cooperation with the block 18, one side of the check block 32 is connected to a limiting sleeve 38, the outer side of the limiting sleeve 38 is connected to a connecting rod 33, the connecting rod 33 is vertically connected to the outer side of the limiting sleeve 38, and the connecting rod 33, the sliding rod 35 and the detection tube 12 are on the same axis, the other end of the connecting rod 33 is connected to a flip gear 16, the fixed frame 28 is rotatably connected to one side of the detection tube 12, the limiting plate 7 is connected to the limiting strip 15, and the limiting strip 16 is connected to the limiting plate 7. A limiting groove 24 is provided on 15, and a connecting rod 33 is slidably connected to the limiting groove 24. Before and after the flip gear 16, the connecting rod 33 will rise and fall on the limiting groove 24, wherein when the rack 14 is rotated to cooperate with the flip gear 16, it can support the flip gear 16 to rise in height, that is, the earphone is in a tilted state during detection, and is in a horizontal state when the earphone is flipped. The detection state of the earphone can be easily judged through this structural feature, and the tilted earphone can be better inspected for appearance defects. A clamping member for fixing the earphone is connected to the fixing frame 28.

[0023] Specifically, Figure 4 and Figure 5 As shown, an arc block 30 is connected to the outside of the fixing frame 28, a collar 21 is rotatably connected to the arc block 30, a collar 1 20 is rotatably connected to the outside of the detection tube 12, a connecting frame 17 is connected between the collar 1 20 and the collar 2 21, the fixing frame 28 and the detection tube 12 can cooperate with each other through the connecting frame 17, and relative rotation can occur between the structures, and the setting of the connecting frame 17 will not interfere with the rotation of the clamping frame 22.

[0024] Specifically, Figure 4 and Figure 5 As shown, the clamping member includes a clip 27, the clip 27 structure is also made of transparent material, and the inner side of the clip 27 is soft, which can provide good protection for the earphones. The outer side of the clip 27 is connected to the clamping frame 22, and the clamping frame 22 is slidably connected to the outer side of the fixed frame 28. One end of the clamping frame 22 is rotatably connected to a T-frame 31, and a slide bar 35 and a spring 1 37 are connected to the outer side of the T-frame 31. A block 18 is rotatably connected to the T-frame 31. A slide groove 2 41 is provided on the fixed frame 28. The T-frame 31 is slidably connected to the slide groove 2 41, and one end of the spring 1 37 is connected to one end of the slide groove 2 41. By setting the spring 1 37 structure, the T-frame 31 can be pushed to abut against the other end of the slide groove 2 41.

[0025] Specifically, Figure 4As shown, a slide groove 34 is provided on the clamping frame 22, and a positioning button 29 is connected to the fixed frame 28. The positioning button 29 is slidably connected to the slide groove 34. When the T-shaped frame 31 moves, it can drive the clamping frame 22 connected to the T-shaped frame 31 to move. At this time, the clamping frame 22 rotates around the T-shaped frame 31, and the positioning button 29 and the slide groove 34 slide against each other.

[0026] Specifically, Figure 5 As shown, one end of the slide rod 35 is connected to an abutment plate 36, and the setting of the abutment plate 36 plays a good protective role on one end of the earphone. A push block 39 is slidably connected to the limit sleeve 38, and the lower end of the push block 39 is connected to a spring 2 40, and the other end of the spring 2 40 is connected to the check block 32. By setting the push block 39, the structure can push the card block 18 and the check block 32 to separate. At this time, the card block 18 structure deflects around the T-frame 31. The setting of the push block 39 structure avoids a close fit between the card block 18 and the check block 32. Gravity alone cannot separate the card block 18 and the check block 32 from each other. The card block 18 structure can be easily pushed by the gravity of the push block 39 and the elastic force of the spring 2 40 structure.

[0027] In summary, the present embodiment provides a device for detecting defects in earphone shells. When it is necessary to detect defects in the earphone shell, the operator needs to insert the long handle of the earphone into the detection tube 12. The detection tube 12 is mostly in a regular cylindrical shape, and it is relatively simple to perform appearance inspection on it. The detection tube 12 is made of transparent plastic material, and the anti-slip strip 26 is made of transparent rubber material. The inspection can be completed in the process of protecting the earphone shell. One end of the earphone inserted into the detection tube 12 will contact the abutment plate 36 structure, and the abutment plate 36 is also provided for inspecting the end of the earphone. To protect the earphone, the earphone is used to push the abutment plate 36 to move. At this time, the T-frame 31 slides on the second slide groove 41, and the spring 1 37 structure is compressed. The T-frame 31 is used to drive the block 18 to move. When one end of the block 18 structure is engaged with one end of the check block 32, the check block 32 can limit the block 18. When the T-frame 31 moves, it can drive the clamping frame 22 to move. When the clamping frame 22 moves, the clamping piece 27 connected to one end of the clamping frame 22 is used to clamp and fix the earphone handle structure. Since the check block 32 limits the block 18, the earphone remains in a fixed state.

[0028] At this time, the motor 4 structure is started, and the turntable 5 is driven to rotate by the motor 4. The detection camera 6 above the turntable 5 is used to perform surround detection on the earphone shell. This detection method can avoid detection blind spots, and the uniform rotation also improves the detection accuracy of the earphone shell. The earphone shell mainly includes a special-shaped part and a long handle part. Since the special-shaped part has an irregular structure, more attention should be paid to the detection of this part during detection. Therefore, the detection of the earphone shell is completed by fixing the long handle part. The structure of the fixed long handle part has the problem of interfering with the detection to a certain extent. However, since the long handle part has a lower requirement on the detection accuracy, the detection method of fixing the long handle part and increasing the detection of the special-shaped part is adopted.

[0029] When the turntable 5 rotates, the transmission belt 8 connected under the turntable 5 can synchronously drive the disc 13 to rotate. When the disc 13 rotates, it can drive the arc-shaped rack 14 to rotate. When the rack 14 rotates to cooperate with the flip gear 16, it can drive the flip gear 16 to rotate with each other. After the two structures cooperate with each other once, they can drive the flip gear 16 to rotate 180°. At this time, the earphone structure also completes a 180° rotation, and cooperates with the detection camera 6 to realize the shell defect detection on the other side of the earphone.

[0030] After the earphone is flipped over, the push block 39 structure can push the card block 18 to separate from one end of the check block 32. At this time, the T-frame 31 is not limited by the check block 32 structure. At this time, the spring 1 37 structure pushes the T-frame 31 to slide on the slide groove 2 41, and the abutment plate 36 is cooperated to complete the pushing of the earphone. Since the structure of the earphone is also limited by the anti-slip strip 26 in the detection tube 12, the earphone will be displaced in the detection tube 12 at this time, instead of pushing the earphone out of the detection tube 12. This means that the earphone has been flipped over, and the inspector needs to wait for the detection camera 6 below to complete a circle of rotation detection. The earphone can be removed only when the earphone is ejected, that is, the shell detection process of a single earphone is completed. The operator only needs to place the earphone on the detection position and wait for the earphone to complete the detection before removing it. There is no restriction on the insertion angle of the earphone, and the earphone placement position can be completed by observing the structure of the card block 18, and the detection completion signal can be learned by whether the earphone pops up. After the earphone pops up, it is necessary to ensure that the detection camera 6 set below completes one circle. The detection method is simple, and one detection personnel can operate multiple devices. Under the premise of ensuring the detection accuracy, the device simplifies the operation steps and improves the detection efficiency.
