Description

Technical Field

[0001] The present invention relates to the technical field of cable detection, and in particular to a charging pile cable appearance detection device. Background Art

[0002] In the production process of charging pile cables, appearance inspection is very necessary. It can promptly detect problems such as damage, scratches, and cracks on the cable surface to avoid the risk of leakage and short circuit due to damage to the insulation layer. Check whether the thickness of the cable is uniform to prevent the current transmission from being affected by uneven conductors. Observe whether the cable is deformed or twisted to avoid damage to the internal structure that affects performance. Ensuring that the cable appearance is qualified can not only improve product quality and ensure the safe and stable operation of the charging pile, but also reduce after-sales maintenance costs.

[0003] There are many deficiencies in the existing appearance inspection of charging pile cables. Traditional inspection methods often rely on manual inspection section by section, which is not only inefficient, but also prone to missed inspections or misjudgments due to the subjectivity and fatigue of manual inspections. For example, some minor damage, scratches or cracks may be difficult to accurately identify with the naked eye, resulting in cables with potential safety hazards entering the market. For automated inspection equipment, the cable is moved continuously and the surface of the cable is captured by a camera. In this case, the cable structure moves, which interferes with the inspection accuracy. The movement of the cable is independent of the appearance inspection structure. When one of the structures is damaged, the other inspection structure does not stop running, resulting in missed inspections. Subsequent maintenance cannot quickly find the missed inspection location, resulting in greater inspection losses.

[0004] Based on this, a charging pile cable appearance detection device is proposed. Summary of the invention

[0005] The purpose of the present invention is to propose a charging pile cable appearance detection device in order to solve the above-mentioned problem.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present 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.

[0029] See also Figure 1-Figure 6 , the present invention provides a technical solution:

[0030] A charging pile cable appearance detection device comprises a shell 1, a display 2 is connected to the upper end of the shell 1, the display 2 can receive the appearance detection data of the cable by the camera component 12, so that the appearance of the cable can be presented in real time on the display 2, a connecting block 3 is connected to the outer side of the shell 1, and a conveying wheel 4 is rotatably connected to the connecting block 3. Since the charging pile cable has a large cross-sectional area and a large mass, it is not easy for a short cable to bend, so no structural bending that interferes with the detection process will occur during the cable transportation process, a fixing plate 5 is fixedly connected inside the shell 1, and a camera component 12 is rotatably connected to one side of the fixing plate 5, and the number of camera components 12 needs to match each other according to the rotation angle of the internal cam 13 to ensure that after the cam 13 completes one rotation, the camera component 12 can perform 360° appearance detection on the outer side of the cable;

[0031] The housing 1 is connected with a motor 8 for driving the camera assembly 12 to rotate. When the cable is inspected for appearance, the motor 8 will move back and forth horizontally. The motor 8 is slidably connected to one side of the fixed plate 5. The output end of the motor 8 is connected to a gear 1 21. When the gear 1 21 and the gear 2 22 are engaged but separated from each other, when the gear 2 22 returns to the initial deflection angle, its structure can also drive the gear 1 21 to reset, ensuring that the subsequent gear 1 21 can be accurately docked with the gear 2 22;

[0032] A cylinder 9 is fixedly connected inside the housing 1. The cylinder 9 is fixedly connected to the inner wall of the housing 1 through a fixed structure. A pushing mechanism for pushing the cable to move is connected to the telescopic end of the cylinder 9.

[0033] Specifically, Figure 4 As shown, a sleeve 14 is rotatably connected to the fixed plate 5, one end of the sleeve 14 is connected to a blade 10, and the blade 10 is connected to a connecting rod 11. The blades 10 are provided in multiple groups, and the multiple groups of 10 blades are evenly connected to the sleeve 14. The camera assembly 12 is connected to the connecting rod 11. When the sleeve 14 is rotatably connected to the fixed plate 5, structural wear will occur between the sleeve 14 and the fixed plate 5. Therefore, the corresponding structure of the equipment is increased with bearings and other structures during installation, thereby improving the stability of the structural rotation connection.

[0034] Specifically, Figure 3 As shown, an adjustment hole 16 is opened on the connecting rod 11, and the camera assembly 12 is slidably connected to the connecting rod 11 through a connecting hoop 15, and the connecting hoop 15 is connected to the adjustment hole 16 by bolts. By connecting the connecting hoop 15 to different adjustment holes 16, the connection position of the camera assembly 12 can be changed, thereby assembling a device structure suitable for appearance inspection of charging pile cables.

[0035] Specifically, Figure 2 and Figure 5 As shown, the sleeve 14 is connected to the gear 22, the limit plate 25 and the cam 13, and the fixed plate 5 is arranged between the limit plate 25 and the cam 13. The fixed plate 5 is used to limit the limit plate 25 and the cam 13 structure, thereby limiting the sleeve 14 structure to avoid structural deviation.

[0036] Specifically, Figure 2 As shown, a slide rail 6 is connected to one side of the fixed plate 5, and a slide frame 7 is slidably connected to the slide rail 6. Two slide rails 6 are provided, and the two slide rails 6 are vertically symmetrically connected to one side of the fixed plate 5. The motor 8 is fixedly connected to the slide frame 7, and a button frame 26 is connected to the slide frame 7. The button frame 26 is connected to the bottom of the slide frame 7, and a control button 27 is connected to the button frame 26. When the gear 2 22 rotates, the gear 22 will also cause wear to the control button 27 structure. The protection of the control button 27 structure is also achieved by setting a gasket structure. A separation piece for promoting the separation between the gear 1 21 and the gear 2 22 is connected to the fixed plate 5.

[0037] Specifically, Figure 4 and Figure 5 As shown, the separation member includes a push rod 18, a deflection shaft 19 is connected to the fixed plate 5, a deflection rod 17 is rotatably connected to the deflection shaft 19, the push rod 18 is rotatably connected to one end of the deflection rod 17, a return spring 20 is connected to the outer side of the deflection rod 17, the return spring 20 can drive the deflection rod 17 to deflect, so that one end of the push rod 18 abuts against the push block 24, wherein the reset of the sliding frame 7 structure is completed by driving the deflection rod 17 to deflect by the return spring 20, the lower end of the deflection rod 17 abuts against the outer side of the cam 13, and one end of the push rod 18 is arranged on one side of the sliding frame 7.

[0038] Specifically, Figure 5 As shown, a slot block 23 is connected to one side of the sliding frame 7, and a push block 24 is connected to one end of the slot block 23. One end of the push rod 18 is slidably connected to the slot block 23, wherein the slot block 23 can limit the push rod 18 structure. When the deflection rod 17 is deflected, the depth of the push rod 18 inserted into the slot block 23 will change.

[0039] Specifically, Figure 6As shown, the pushing mechanism includes an abutment block 31, a push plate 28 is connected to the telescopic end of the cylinder 9, a conveying frame 29 is connected to the push plate 28, a vertical rod 30 is connected to the conveying frame 29, the abutment block 31 is rotatably connected to the vertical rod 30, an abutment spring 32 is connected to the abutment block 31, one end of the abutment block 31 abuts against the outside of the cable, and the abutment spring 32 has the effect of tending to deflect the abutment block 31 to one side of the cable. In order to increase the stability of the transmission, a toothed structure can be added to one end of the abutment block 31 to improve the stability of the clamping and avoid the problem of the abutment block 31 and the outside of the cable slipping against each other when the cable needs to be moved.

[0040] To sum up, the charging pile cable appearance inspection device provided in this embodiment, when the appearance inspection of the charging pile cable is required, sends the cable into the shell 1 to ensure that the cable is clamped between the conveying wheels 4, so that the cable can move stably after the appearance inspection, move the part of the cable that has been inspected out of the shell 1, and move the part of the cable to be inspected into the shell 1.

[0041] Then, the cylinder 9 is started, wherein the cylinder 9 structure is fixedly connected to the inside of the shell 1. After the cylinder 9 is started, its telescopic end drives the push plate 28 to move, thereby driving the motor 8 to move toward the fixed plate 5. At this time, the sliding frame 7 fixedly connected to the motor 8 slides on the slide rail 6, and the gear 1 21 and the gear 2 22 approach each other until the gear 1 21 and the gear 2 22 are completely connected. At this time, the control button 27 structure is abutted by the outer side of the gear 22 and then pressed. The control button 27 has the function of controlling the operation of the motor 8. When the control button 27 is pressed, the motor 8 drives the gear 1 21 to rotate, and the gear 1 21 drives the gear 2 22 to rotate, thereby driving the camera assembly 12 connected to the connecting rod 11 to rotate around the cable, and the camera assembly 12 is used to capture the surface condition of the cable, and the real-time picture is transmitted to the display 2, so that the appearance of the cable can be understood.

[0042] When the gear 22 is rotated, the cam 13 fixedly connected to one side of the gear 22 by the sleeve 14 will also rotate. When the cam 13 rotates, the position where the cam 13 contacts the deflection rod 17 changes. Since there is a position where the diameter changes in the cam 13, this part of the position can push the deflection rod 17 to deflect as the cam 13 rotates. The deflected deflection rod 17 can make one end of the push rod 18 move toward the push block 24, thereby pushing the sliding frame 7 to move away from the fixed plate 5, forcing the gear 1 21 and the gear 2 22 to separate from each other. At this time, the control button 27 structure is not pressed, the motor 8 structure stops running, and the reset spring 20 can drive the deflection rod 17 to deflect, thereby pushing the sliding frame 7 structure to reset, so that the sliding frame 7 moves in the direction away from the fixed plate 5 until the gear Gear 1 21 and gear 2 22 are separated from each other, and the cam 13 has a tapered portion that tends to point vertically downward due to its different mass, so that the cam 13 deflects to the initial state. At this time, the cam 13 completes a complete deflection operation during one detection. The number of camera assemblies 12 can be increased for the deflection angle later, that is, when the rotation angle of the cam 13 for a single operation is 120°, only three groups of camera assemblies 12 are needed to achieve a complete rotation appearance test of the cable. The coverage angle range of the raised structure in the cam 13 also needs to be debugged, so as to select an appropriate cam 13 structure. Since both gear 1 21 and gear 2 22 will enter the initial state before docking, during docking, gear 1 21 can stably dock with gear 2 22 to avoid the problem of collision between tooth structures.

[0043] When the cylinder 9 is started, it can drive the conveyor frame 29 to move toward the fixed plate 5. During the movement, due to the abutment of the abutment block 31, the abutment block 31 can clamp the outside of the cable in the direction of movement, thereby pushing the cable to move, thereby changing the cable position used by the camera assembly 12, and replacing the cable inspection position for the next cable appearance inspection. When the cylinder 9 is extended to the maximum state, the subsequent cylinder 9 will automatically contract, so that the push plate 28 and other structures are reset, and then wait for some cables to complete the appearance inspection. At this time, the cylinder 9 continues to reciprocate and extend.

[0044] The equipment can be used to perform automated appearance inspection on charging pile cables. During the cable appearance inspection, the movement of the cable and the inspection of the cable are performed alternately. The cable is in a stationary state during the inspection, which improves the stability of the cable structure during the inspection and ensures that the transmission structure can be accurately docked. The initialization and reset steps of the transmission structure can avoid subsequent structural damage due to partial structural operation errors to the greatest extent, effectively ensuring the stability of the cable appearance inspection operation, and quickly locating the missed inspection position during subsequent maintenance.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
