Description

Technical Field

[0001] The present invention relates to the technical field of image acquisition equipment, and in particular to a monitoring system based on an image acquisition device. Background Art

[0002] Data transmission harnesses are used for data signal transmission in automobiles. During the processing, the outer conductor needs to be pressed after stripping the wire. The internal center terminal and the crimped outer conductor must have good concentricity to ensure the stability of signal transmission. The existing technology usually uses industrial cameras for automatic imaging, so as to directly perform rapid quality inspection on batch data transmission harnesses.

[0003] However, during the long-term use of the prior art, it was found that there are still certain drawbacks, such as: 1. The outer conductor of the data transmission harness is crimped on the outside and often deforms in an elliptical trend during the multiple clamping and transportation collision processes during positioning, which makes it impossible for the imaging focus of the industrial camera to accurately match the center of the crimped outer conductor. The internal center terminal is judged to have a large concentricity deviation, which causes the quality monitoring system to often misjudge it as a quality problem and automatically alarm, requiring material removal and reshaping and re-image inspection; 2. During the image acquisition process, the data transmission harness is imaged and transported horizontally as a whole, and the harness end is slightly warped, causing the internal center terminal to be warped as well, which will also cause unnecessary misjudgment and affect quality inspection and subsequent processing efficiency. Summary of the invention

[0004] The object of the present invention is to provide a monitoring system based on an image acquisition device to solve the above-mentioned defects caused by the prior art.

The intermittent feeding assembly is rotatably mounted on the straightening and shaping mechanism and is used to position a data transmission harness and transport it at a fixed frequency. The straightening and shaping mechanism is mounted on the frame and is used to straighten and shape the central terminal and outer conductor of the data transmission harness respectively.

[0006] Preferably, the straightening and shaping mechanism includes a driving motor, a lever and a notched turntable, the driving motor is mounted on the frame through a mounting frame, the lever and the notched turntable are both mounted on the output shaft of the driving motor, an extension shaft is also coaxially mounted on the output end of the driving motor, the upper end of the lever is detachably mounted with a shaping outer convex head, the upper end of the extension shaft passes through an avoidance circular hole and is detachably mounted with a straightening inner concave head, a rotating shaft is also rotatably mounted on the mounting frame, a rotating part cooperating with the lever and the notched turntable is mounted on the rotating shaft, and the intermittent feeding assembly is mounted on the upper end of the rotating shaft.

[0007] Preferably, the intermittent feeding assembly includes a positioning upper turntable, an open lower turntable and a negative pressure pump.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0020] like Figures 1 to 5 As shown, a monitoring system based on an image acquisition device includes a frame, a monitoring camera, an intermittent feeding component 4 and a straightening and shaping mechanism 3. The frame 1 is provided with a loading frame 5 and an unloading frame 6. The frame 1 is also provided with an avoidance circular hole 7. The monitoring camera 2 is installed on the frame 1. The intermittent feeding component 4 is rotatably installed on the straightening and shaping mechanism 3, and is used to position the data transmission harness 8 and transport it at a fixed frequency. The straightening and shaping mechanism 3 is installed on the frame 1, and is used to straighten and shape the central terminal 81 and the outer conductor 82 of the data transmission harness 8 respectively.

[0021] In this embodiment, the straightening and shaping mechanism 3 includes a driving motor 31, a lever 32 and a notched turntable 33. The driving motor 31 is installed on the frame 1 through a mounting frame 34. The lever 32 and the notched turntable 33 are both installed on the output shaft of the driving motor 31. The output end of the driving motor 31 is also coaxially installed with an extension shaft 35. The upper end of the lever 32 is detachably installed with a shaping outer convex head 36. The upper end of the extension shaft 35 passes through the avoidance circular hole 7 and is detachably installed with a straightening inner concave head 37. A rotating shaft 38 is also rotatably installed on the mounting frame 34. A rotating part 39 that cooperates with the lever 32 and the notched turntable 33 is installed on the rotating shaft 38. The intermittent feeding assembly 4 is installed on the upper end of the rotating shaft 38. The shaping end of the shaping outer convex head 36 has a horizontal motion trajectory that is concentric with the straightening inner concave head 37.

[0022] Here, the model selected for the driving motor 31 is Y80M1-4.

[0023] In this embodiment, the intermittent feeding assembly 4 includes a positioning upper turntable 41, an open lower turntable 42 and a negative pressure pump 43. The positioning upper turntable 41 is coaxially installed on the upper end of the rotating shaft 38. A plurality of evenly distributed elastic negative pressure bands 44 are annularly arranged in the positioning upper turntable 41. There are a plurality of negative pressure pumps 43 and they are respectively installed on the upper end of the positioning upper turntable 41. The negative pressure pump 43 is connected to the adjacent elastic negative pressure bands 44. The open lower turntable 42 is connected to the positioning upper turntable 41 through a material placing barrel 45. The side end of the material placing barrel 45 that cooperates with the elastic negative pressure band 44 is opened, and the data transmission harness 8 is placed in the material placing barrel 45.

[0024] It should be noted that a material sensor is provided at the lower part of the material placing barrel 45 , which can identify the feeding depth of the data transmission harness 8 to control the start and stop of the negative pressure pump 43 .

[0025] In this embodiment, the imaging end of the monitoring camera 2 cooperates with the open lower turntable 42 in the vertical direction, the central terminal 81 cooperates with the straightening inner concave head 37 in the vertical direction, and the outer wall of the outer conductor 82 cooperates with the shaping outer convex head 36 in the vertical direction.

[0026] Working process and principle: During use of the present invention, the data transmission harness 8 to be inspected is first placed in the material placement barrel 45 close to the positioning upper turntable 41 through the loading rack 5, and the central terminal 81 and the outer conductor 82 at its end are placed downward. When the lower end of the outer conductor 82 drops to be flush with the port of the material placement barrel 45, the negative pressure pump 43 is started to pull the elastic negative pressure band 44 to tighten to position the data transmission harness 8 in the material placement barrel 45, and then the driving motor 31 is started so that its output end drives the lever 32, the notched turntable 33 and the extension shaft 35 to rotate synchronously. When the lever 32 rotates to a state of matching with the rotating member 39, the rotating member 39 is driven to rotate at a uniform speed of one-quarter of a circle, and the positioning upper turntable 41 is driven to follow the rotation shaft 38. When the lever 32 is out of match with the rotating member 39, the rotation of the notched turntable 33 will not drive the rotating member 39 to follow, that is, the data transmission harness 8 in the material placement barrel 45 rotates synchronously and stops in one-quarter of a circle.

[0027] At this time, the negative pressure pump 43 in the open state is turned off, so that the data transmission harness 8 in the placing barrel 45 falls onto the straightening inner concave head 37, and the uninterrupted uniform rotation of the extension shaft 35 drives the straightening inner concave head 37 at the upper end to rotate synchronously. Under the action of the concave structure at the upper end of the straightening inner concave head 37, the lower end of the central terminal 81 in the data transmission harness 8 is in a vertical state, and the synchronous rotation of the lever 32 can drive the shaping outer convex head 36 to correct the outer wall of the outer conductor 82 for a whole circumference, so that it reaches a qualified roundness without tearing or damaging its thinner side wall structure;

[0028] As the lever 32 continues to rotate one circle, when the rotating part 39 is moved again to the starting state of the next regular rotation, the negative pressure pump 43 is turned on again to position, clamp and straighten the center terminal 81 and shape the data transmission harness 8 after the outer conductor 82 is shaped, and then rotated to just above the imaging focus of the monitoring camera 2, so that the imaging focus of the monitoring camera 2 is precisely aligned with the center of the crimped outer conductor 82. At this time, the image of the vertical center terminal 81 without warping and the outer conductor 82 without deformation is captured, and the actual concentricity can be accurately monitored and judged. If there is no quality problem, the material is directly discharged from the unloading rack 6, and the presence of quality problems can be detected and identified as an alarm.

[0029] Based on the above, the present invention sets a straightening and shaping mechanism 3 and an intermittent feeding assembly 4 on the frame 1, and the output end of the driving motor 301 drives the lever 32, the notched turntable 33 and the extension shaft 35 to rotate synchronously, so that the shaping outer convex head 36 and the straightening inner concave head 37 continue to rotate, and the rotating member 39 drives the data transmission harness 8 in the placing barrel 45 to rotate intermittently, so that for the data transmission harness 8 in the vertical state, the straightening inner concave head 37 straightens the center terminal 81, and the shaping outer convex head 36 corrects the outer wall of the outer conductor 82 throughout the whole circle, ensuring that the imaging focus of the subsequent imaging is accurately aligned with the center of the crimped outer conductor 82, thereby avoiding misjudgment of the quality monitoring system.

[0030] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
