Description

Technical Field

[0001] This invention belongs to the field of detection technology, specifically an HDMI line deformation detection device. Background Technology

[0002] HDMI stands for High Definition Multimedia Interface, a digital video / audio interface technology. An HDMI cable is simply a connection cable between multiple high-definition multimedia devices. It can transmit uncompressed high-definition video and multi-channel audio data in high quality. HDMI cables undergo deformation testing after manufacturing.

[0003] However, most existing HDMI cables undergo deformation testing manually through visual and tactile inspection. This involves visually inspecting the cable for obvious deformation or damage and touching it to assess its smoothness and temperature. This method is inefficient and can be further hampered by dirt or grime on the cable.

[0004] Therefore, the present invention provides an HDMI line deformation detection device. Summary of the Invention

[0010] Both the first and second fixing rings are equipped with several freely rotatable ball bearings. Both the first and second fixing rings are made of acrylic material. The HDMI cable is located inside the first and second fixing rings.

[0011] It also includes a wiping component mounted on the mounting bracket, which can wipe and clean the HDMI cable while the slide stretches and straightens it.

[0012] Furthermore, the wiping assembly includes a sleeve fixedly connected to the mounting bracket, a connecting rod fixedly installed on the output end of the electric push rod, and a piston plate fixedly installed inside the sleeve at the end of the connecting rod away from the electric push rod. The piston plate is slidably and sealingly connected to the inner wall of the sleeve.

[0013] Furthermore, it also includes an arc-shaped block fixedly installed on the first fixed ring and the second fixed ring, the arc-shaped block having a cavity inside, and a connecting cylinder communicating with it fixedly installed on the sleeve;

[0014] A pair of elastic tubes are fixedly installed on the connecting cylinder. The pair of elastic tubes are fixedly connected to the arc-shaped blocks on the first and second fixing rings, respectively. An elastic membrane is fixedly installed inside the cavity, and a sponge block is provided on the surface of the elastic membrane.

[0015] Furthermore, the mounting bracket is equipped with a cleaning component that can cooperate with the wiping component, which can prevent impurities from accumulating during the wiping process and affecting the detection of the detection probe.

[0016] Furthermore, the cleaning component includes a groove formed on the slide table, and an elastic block with a hollow interior is fixedly installed on the inner wall of the groove. A pair of air pipes are fixedly installed on the elastic block, and the end of the air pipe away from the elastic block is connected to a hollow ring fixed to the surface of the first and second fixed rings through a connecting plate. Several nozzles facing the sponge block are fixedly installed on the hollow rings, and several pairs of extrusion parts are fixedly installed on the surface of the guide rail.

[0017] Furthermore, the extrusion member is rotatably connected to the guide rail via a rotating shaft, and the extrusion member and the rotating shaft can only rotate in one direction.

[0018] Furthermore, the steering mechanism includes a first motor fixedly mounted on the surface of the mounting bracket, and a drive head fixedly mounted on the output shaft of the first motor. The drive head is convex, and a portion of the drive head can abut against an HDMI cable.

[0019] Furthermore, the rotating frame is provided with an auxiliary feeding mechanism, which includes an installation cavity opened on the bracket. A second motor is fixedly installed in the installation cavity. A fixing rod is fixedly installed on the output shaft of the second motor. A lever is fixedly installed at the end of the fixing rod away from the second motor. A placement slot opened on the base is provided below the rotating frame.

[0020] Furthermore, the paddle block is provided with a chamfer.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. The HDMI cable deformation detection device of the present invention, when the motor switch is turned on, the output shaft of the motor and the drive gear cooperate to drive the rotating frame to rotate, so that the detection probe rotates synchronously and enters the detection state. Then, the electric push rod is activated, so that the output end of the electric push rod retracts and drives the first fixing ring away from the second fixing ring. Then, the HDMI cable is placed between the first fixing ring and the second fixing ring. The output end of the electric push rod is controlled to drive the first fixing ring and the second fixing ring to engage and bind the HDMI cable. Then, the cylinder in a pair of slides drives a pair of slides to move away from each other, stretching and unfolding the HDMI cable engaged by the first fixing ring and the second fixing ring. At this time, the detection probe can perform all-round detection of the HDMI cable. When the detection probe moves to both ends of the HDMI cable, the detection probe can also perform deformation detection on the plug part, thereby achieving a better detection effect, eliminating the need for manual visual inspection and touch inspection, and thus improving the detection efficiency.

[0023] It should be noted that the first and second fixing rings made of acrylic material allow the detection probe to pass through the first and second fixing rings to detect HDMI cables that are blocked by the first and second fixing rings, thus improving detection efficiency.

[0024] Furthermore, the ball bearings inside the first and second fixing rings facilitate the movement of the HDMI cable between the first and second fixing rings, preventing the HDMI cable from being scratched by the inner side of the first and second fixing rings.

[0025] 2. In the HDMI line deformation detection device of the present invention, when the output end of the electric push rod extends, it cooperates with the connecting rod to drive the piston plate to move in the sleeve, so that the air in the sleeve is compressed into the connecting cylinder and enters the cavity of the arc block along the elastic tube on the connecting cylinder, causing the elastic membrane in the cavity to expand and drive the sponge block to contact the HDMI line. When the slide moves, the sponge block can wipe and clean the HDMI line, avoiding impurities adhering to the HDMI line from affecting the detection effect of the detection probe.

[0041] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0042] like Figures 1 to 8 As shown, the HDMI line deformation detection device of the present invention includes a base 10. A rotating detection mechanism is provided on the surface of the base 10. The rotating detection mechanism includes a rotating frame 12 rotatably mounted on the base 10. A pair of brackets 16 are fixedly mounted on the rotating frame 12. A detection probe 17 is fixedly mounted on the brackets 16. A boss 11 with a pair of motors 13 inside is fixedly mounted on the base 10. The output shafts of the motors 13 are all fixedly mounted with drive teeth 14. The rotating frame 12 has a tooth groove 15 that meshes with the drive teeth 14.

[0043] The stretching mechanism 20, mounted on the boss 11, can cooperate with the rotation detection mechanism to stretch and straighten the HDMI cable, making it easier for the rotation detection mechanism to perform all-round detection on the HDMI cable.

[0044] The steering mechanism 30, which is mounted on the mounting bracket 23 included in the stretching mechanism 20, can further improve the detection efficiency of the rotary detection mechanism.

[0045] In one embodiment of the present invention, the stretching mechanism 20 includes a guide rail 21 attached to the surface of the boss 11 by screws. A pair of slides 22 driven by cylinders are provided on the guide rail 21. Each slide 22 is fixedly mounted with a mounting bracket 23. An electric push rod 26 is fixedly mounted on the mounting bracket 23. A first fixing ring 24 is fixedly mounted on the output end of the electric push rod 26. A second fixing ring 25 that cooperates with the first fixing ring 24 is fixedly mounted on each mounting bracket 23.

[0046] The first fixing ring 24 and the second fixing ring 25 are each provided with a number of freely rotating ball bearings 27. The first fixing ring 24 and the second fixing ring 25 are both made of acrylic material. The HDMI cable is located inside the first fixing ring 24 and the second fixing ring 25.

[0047] It also includes a wiping component 231 mounted on the mounting bracket 23, which can wipe and clean the HDMI cable while the slide 22 stretches and extends it.

[0048] During operation, the switch of motor 13 is turned on, and the output shaft of motor 13 cooperates with the drive gear 14 to drive the rotating frame 12 to rotate, so that the detection probe 17 rotates synchronously and enters the detection state. Then, the electric push rod 26 is activated, and the output end of the electric push rod 26 retracts, causing the first fixing ring 24 to move away from the second fixing ring 25. Then, the HDMI cable is placed between the first fixing ring 24 and the second fixing ring 25. The output end of the electric push rod 26 is controlled to drive the first fixing ring 24 and the second fixing ring 25 to engage and bind the HDMI cable. Then, the cylinder in the pair of slides 22 drives the pair of slides 22 to move away from each other, stretching and unfolding the HDMI cable engaged by the first fixing ring 24 and the second fixing ring 25. At this time, the detection probe 17 can perform all-round detection of the HDMI cable. When the detection probe 17 moves to both ends of the HDMI cable, the detection probe 17 can also perform deformation detection on the plug part, thereby achieving a better detection effect without the need for manual visual inspection and touch inspection, thus improving the detection efficiency.

[0049] It should be noted that the first fixing ring 24 and the second fixing ring 25 made of acrylic material enable the detection probe 17 to pass through the first fixing ring 24 and the second fixing ring 25 to detect the HDMI cable that is blocked by the first fixing ring 24 and the second fixing ring 25, thereby improving the detection efficiency.

[0050] Furthermore, the ball bearings 27 inside the first fixing ring 24 and the second fixing ring 25 facilitate the movement of the HDMI cable within the first fixing ring 24 and the second fixing ring 25, preventing the HDMI cable from being scratched by the inner side of the first fixing ring 24 and the second fixing ring 25.

[0051] In one embodiment of the present invention, the wiping assembly 231 includes a sleeve 232 fixedly connected to the mounting bracket 23, a connecting rod 233 fixedly installed on the output end of the electric push rod 26, and a piston plate 234 fixedly installed at the end of the connecting rod 233 away from the electric push rod 26 inside the sleeve 232. The piston plate 234 is slidably and sealingly connected to the inner wall of the sleeve 232.

[0052] Specifically, it also includes an arc-shaped block 237 fixedly installed on the first fixing ring 24 and the second fixing ring 25. The arc-shaped block 237 has a cavity inside, and a connecting cylinder 235 communicating with it is fixedly installed on the sleeve 232.

[0053] A pair of elastic tubes 236 are fixedly installed on the connecting cylinder 235. The pair of elastic tubes 236 are fixedly connected to the arc-shaped blocks 237 on the first fixing ring 24 and the second fixing ring 25, respectively. An elastic membrane 238 is fixedly installed in the cavity. A sponge block 239 is provided on the surface of the elastic membrane 238.

[0054] During operation, when the output end of the electric push rod 26 extends, it cooperates with the connecting rod 233 to drive the piston plate 234 to move inside the sleeve 232. This compresses the air inside the sleeve 232 into the connecting cylinder 235, and then enters the cavity of the arc-shaped block 237 along the elastic tube 236 on the connecting cylinder 235. This causes the elastic membrane 238 inside the cavity to expand and drive the sponge block 239 to contact the HDMI cable. When the slide 22 moves, the sponge block 239 can wipe and clean the HDMI cable, preventing impurities from adhering to the HDMI cable and affecting the detection effect of the detection probe 17.

[0055] In one embodiment of the present invention, the mounting bracket 23 is equipped with a cleaning component 221 that can cooperate with the wiping component 231, which can prevent impurities from accumulating during the wiping process of the wiping component 231 and affecting the detection of the detection probe 17.

[0056] Specifically, the cleaning component 221 includes a groove 222 formed on the slide table 22. An elastic block 223 with a hollow interior is fixedly installed on the inner wall of the groove 222. A pair of air pipes 224 are fixedly installed on the elastic block 223. The end of the air pipe 224 away from the elastic block 223 is connected to a hollow ring 226 fixed to the surface of the first fixing ring 24 and the second fixing ring 25 through a connecting plate 225. Several nozzles 227 facing the sponge block 239 are fixedly installed on the hollow ring 226. Several pairs of extrusion parts 228 are fixedly installed on the surface of the guide rail 21.

[0057] During operation, when a pair of slides 22 move away from each other on the guide rail 21, several pressing parts 228 on the guide rail 21 continuously press the elastic block 223. After the elastic block 223 is pressed, the air inside enters the hollow ring 226 along the air pipe 224 and is sprayed along the nozzle 227 onto the sponge block 239, cleaning away the impurities that have accumulated on one side due to the wiping of the sponge block 239, thereby further improving the detection efficiency of the detection probe 17.

[0058] Specifically, the extrusion member 228 is rotatably connected to the guide rail 21 via a rotating shaft, and the extrusion member 228 and the rotating shaft can only rotate in one direction.

[0059] When a pair of slides 22 move away from each other on the guide rail 21, the extruder 228 can only rotate in one direction. When it comes into contact with the elastic block 223, it will compress the elastic block 223. When a pair of slides 22 move closer to each other on the guide rail 21, when the slide 22 comes into contact with the extruder 228, it will drive the extruder 228 to rotate on the rotating shaft. After the slide 22 passes the extruder 228, the extruder 228 will rotate one revolution, which facilitates the use of the equipment.

[0060] In one embodiment of the present invention, the steering mechanism 30 includes a first motor 31 fixedly mounted on the surface of the mounting bracket 23, and a drive head 32 fixedly mounted on the output shaft of the first motor 31. The drive head 32 is convex and a portion of the drive head 32 can abut against an HDMI cable.

[0061] When the HDMI cable is stretched, the first motor 31 is activated. The first motor 31 drives the drive head 32 to rotate. When the outer protrusion of the drive head 32 contacts the HDMI cable, it will drive the HDMI cable to rotate within the first fixing ring 24 and the second fixing ring 25, thereby facilitating the detection probe 17 to perform a more comprehensive detection of the HDMI cable.

[0062] When the stretching mechanism 20 stretches the HDMI cable, the outer protrusion of the drive head 32 does not contact the HDMI cable, thus facilitating the stretching mechanism 20 to stretch the HDMI cable.

[0063] In one embodiment of the present invention, the rotating frame 12 is provided with an auxiliary feeding mechanism 40. The auxiliary feeding mechanism 40 includes a mounting cavity 41 opened on the bracket 16. A second motor 42 is fixedly installed in the mounting cavity 41. A fixing rod 43 is fixedly installed on the output shaft of the second motor 42. A lever 44 is fixedly installed at the end of the fixing rod 43 away from the second motor 42. A placement groove 18 opened on the base 10 is provided below the rotating frame 12.

[0064] Specifically, the dial 44 is provided with a chamfer.

[0065] During operation, after the detection probe 17 completes the detection of the HDMI cable, if the HDMI cable shows no deformation, the electric push rod 26 will retract, causing the first fixing ring 24 to move away from the second fixing ring 25, thus releasing the HDMI cable from its restraint. Subsequently, the second motor 42 will start, causing the fixing rod 43 to be parallel to the detection probe 17. As the rotating frame 12 rotates, the chamfered edge of the lever 44 will pull the HDMI cable out from the first fixing ring 24 and the second fixing ring 25, and it will fall into the placement slot 18 and be collected. If the HDMI cable shows deformation, the device will stop operating, and the operator will remove the HDMI cable with deformation before re-detecting it.

[0066] Working principle: When the switch of motor 13 is turned on, the output shaft of motor 13 and drive gear 14 cooperate to drive the rotating frame 12 to rotate, so that the detection probe 17 rotates synchronously and enters the detection state. Then, the electric push rod 26 is activated, so that the output end of the electric push rod 26 retracts and drives the first fixing ring 24 away from the second fixing ring 25. Then, the HDMI cable is placed between the first fixing ring 24 and the second fixing ring 25. The output end of the electric push rod 26 is controlled to drive the first fixing ring 24 and the second fixing ring 25 to engage and bind the HDMI cable. Then, the cylinder in the pair of slides 22 drives the pair of slides 22 to move away from each other, stretching and unfolding the HDMI cable engaged by the first fixing ring 24 and the second fixing ring 25. At this time, the detection probe 17 can perform all-round detection of the HDMI cable. When the detection probe 17 moves to both ends of the HDMI cable, the detection probe 17 can also perform deformation detection on the plug part, thereby achieving a better detection effect without the need for manual visual inspection and touch inspection, thus improving the detection efficiency.

[0067] It should be noted that the first fixing ring 24 and the second fixing ring 25 made of acrylic material enable the detection probe 17 to pass through the first fixing ring 24 and the second fixing ring 25 to detect the HDMI cable that is blocked by the first fixing ring 24 and the second fixing ring 25, thereby improving the detection efficiency.

[0068] Furthermore, the ball bearings 27 inside the first fixing ring 24 and the second fixing ring 25 facilitate the movement of the HDMI cable within the first fixing ring 24 and the second fixing ring 25, preventing the HDMI cable from being scratched by the inner side of the first fixing ring 24 and the second fixing ring 25.

[0069] When the output end of the electric push rod 26 extends, it cooperates with the connecting rod 233 to drive the piston plate 234 to move inside the sleeve 232. This compresses the air inside the sleeve 232 into the connecting cylinder 235, and then along the elastic tube 236 on the connecting cylinder 235 into the cavity of the arc block 237. This causes the elastic membrane 238 inside the cavity to expand and drive the sponge block 239 to contact the HDMI cable. When the slide 22 moves, the sponge block 239 can wipe and clean the HDMI cable, preventing impurities from adhering to the HDMI cable and affecting the detection effect of the detection probe 17.

[0070] When a pair of slides 22 move away from each other on the guide rail 21, several pressing parts 228 on the guide rail 21 will continuously press the elastic block 223. After the elastic block 223 is pressed, the air inside will enter the hollow ring 226 along the air pipe 224 and spray it along the nozzle 227 onto the sponge block 239, cleaning away the impurities that have accumulated on one side due to the wiping of the sponge block 239, thereby further improving the detection efficiency of the detection probe 17.

[0071] When a pair of slides 22 move away from each other on the guide rail 21, the extruder 228 can only rotate in one direction. When it comes into contact with the elastic block 223, it will compress the elastic block 223. When a pair of slides 22 move closer to each other on the guide rail 21, when the slide 22 comes into contact with the extruder 228, it will drive the extruder 228 to rotate on the rotating shaft. After the slide 22 passes the extruder 228, the extruder 228 will rotate one revolution, which facilitates the use of the equipment.

[0072] When the HDMI cable is stretched, the first motor 31 is activated, which drives the drive head 32 to rotate. When the outer protrusion of the drive head 32 contacts the HDMI cable, it will drive the HDMI cable to rotate within the first fixing ring 24 and the second fixing ring 25, thereby facilitating the detection probe 17 to perform a more comprehensive detection of the HDMI cable.

[0073] When the stretching mechanism 20 stretches the HDMI cable, the outer protrusion of the drive head 32 does not contact the HDMI cable, thus facilitating the stretching mechanism 20 to stretch the HDMI cable.

[0074] After the detection probe 17 completes the test on the HDMI cable, if the HDMI cable shows no deformation, the electric push rod 26 will retract, causing the first fixing ring 24 to move away from the second fixing ring 25, thus releasing the HDMI cable from its restraint. Then, the second motor 42 will start, causing the fixing rod 43 to be parallel to the detection probe 17. As the rotating frame 12 rotates, the chamfer of the lever 44 will pull the HDMI cable out from the first fixing ring 24 and the second fixing ring 25, and it will fall into the placement slot 18 and be collected. If the HDMI cable shows deformation, the device will stop operating. After the staff removes the HDMI cable with deformation, the test will be performed again.

Figure 1 Based on the perspective of the observer, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
