Description

Technical Field

[0001] The utility model relates to the technical field of cable processing equipment, in particular to a clamping vision detection device. Background Art

[0002] In the production process of cables, the accurate arrangement of wire harness terminals is crucial. Usually, the wire harness terminals need to be detected and processed before subsequent operations. For example, in some specific processing links, there are strict requirements for the arrangement positions of the wire harness terminals. Therefore, it is necessary to adjust the original sorting of the wire harness terminals to ensure that the wire harness terminals can enter the next process with the correct arrangement positions.

[0003] In the related art, a vision detection device is usually used to identify the arrangement of wire harness terminals. When the detection system finds that the arrangement position needs to be adjusted, a special tool or fixture is usually used for manual adjustment to rearrange the wire harness terminals.

[0004] However, this manual adjustment method is mainly applicable to small-batch production or situations that require specific processing. In the process of large-batch production, manual adjustment not only requires a large amount of manpower, but also significantly increases the time cost and operation complexity. In addition, it is difficult to guarantee the accuracy and consistency of manual adjustment, which may lead to quality problems in subsequent processes. Therefore, when producing cables on a large scale, it is difficult to meet the requirements of efficiency and cost control by relying on the manual adjustment method, and it is urgent to introduce an automated solution to optimize the production process.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0031] It should be noted that when an element is referred to as "fixed to" another element, it can be directly on the other element or there may also be an intermediate element. When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration and do not represent the only implementation manner.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used in the description of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0033] As Figures 1 to 8 shown, the clamping vision detection device includes: a clamping mechanism 1, a camera system 2 and a rotating mechanism 3. The clamping mechanism 1 includes clamping jaws 11, and the clamping jaws 11 are used for clamping the wire harness terminals; the camera system 2 includes a vision detection device 21, and the normal direction of the shooting surface of the vision detection device 21 coincides with the axis direction of the wire harness terminals; the rotating mechanism 3 includes a rotating shaft 31; wherein, one end of the rotating shaft 31 is fixed to the clamping mechanism 1, and the other end of the rotating shaft 31 is connected to the camera system 2. As Figure 1 shown, the vision detection device 21 is installed at the other end of the rotating shaft 31, and the camera system 2 can shoot the wire harness terminals clamped by the clamping jaws 11 through the hollow rotating shaft 31 to realize the vision detection of the target object. During the working process of the embodiment of the present utility model, the wire harness terminals enter the device and are first clamped by the clamping jaws 11 in the clamping mechanism 1. When the vision detection device 21 in the camera system 2 recognizes that the wire harness terminals need to be modified in the arrangement position, the rotating mechanism 3 drives the rotation of the wire harness terminals in the clamping mechanism 1 through the rotation of the rotating shaft 31. During the whole working process, since the normal direction of the shooting surface of the vision detection device 21 coincides with the axis direction of the rotating shaft 31, it can directly aim at the wire harness terminals clamped by the clamping jaws 11, thereby improving the detection accuracy and efficiency; the rotating shaft 31 in the rotating mechanism 3 can rotate 360°, that is, it can directly rotate the wire harness terminals to the required position arrangement in one step, improving the working efficiency and the automation level of the production line.

[0034] When specifically adjusting the arrangement position of the wire core of the wire harness terminal, reference can be made toFigure 8 In the wire harness, the first wire core 7 and the second wire core 8 are wrapped by a filler 9. When the camera system 2 detects that the wire core arrangement position of the wire harness terminal does not conform to the setting, the rotation mechanism 3 drives the rotation of the clamping jaws 11, thereby realizing the adjustment of the wire core arrangement position of the wire harness terminal.

[0035] In some embodiments of the present invention, the rotation mechanism 3 further includes a first driving motor 32 and a rotation driving member 33, and the rotation driving member 33 connects the first driving motor 32 and the rotation shaft 31. As Figure 2 、 Figure 3 shown, when the vision detection device 21 in the camera system 2 recognizes that the wire core arrangement of the wire harness terminal needs to be modified in terms of the arrangement position, the first driving motor 32 transmits power through the rotation driving member 33 to drive the rotation of the rotation shaft 31, and the rotation of the rotation shaft 31 causes the clamping jaws 11 to rotate synchronously. When the wire cores are adjusted to the required arrangement position, the rotation mechanism 3 stops working. It should be noted here that the rotation driving member 33 can be a belt drive. The rotational motion output by the first driving motor 32 is transmitted to the driving wheel. The driving wheel is part of the belt drive system and is fixed on the shaft of the first driving motor 32. When the driving wheel rotates, it drives the transmission belt to move. The transmission belt transmits the power of the driving wheel to the driven wheel through friction. The driven wheel is connected to the rotation shaft 31. Therefore, the rotation of the driven wheel directly drives the rotation of the rotation shaft 31. In this way, the transmission belt transmits the power of the first driving motor 32 to the rotation shaft 31 to realize the adjustment of the arrangement position of the wire harness terminal; the belt drive structure is relatively simple, the manufacturing and maintenance costs are low, and the transmission belt has elasticity, which can absorb certain impacts and vibrations, making the transmission system operate more smoothly and reducing equipment wear or detection errors caused by vibrations. Of course, in addition to the above belt drive method, the rotation driving member 33 can also adopt methods such as gear drive, chain drive, and hydraulic drive, etc., and should be selected according to the application scenario and requirements.

[0036] Furthermore, in some embodiments of the present invention, there is also a bracket 4. The bracket 4 is provided with a slide rail 41, and the clamping mechanism 1 is provided with a slider 12 that cooperates with the slide rail 41. As Figures 1-3 shown, the cooperation between the slide rail 41 and the slider 12 enables the clamping mechanism 1 to smoothly move along the direction of the slide rail 41 on the bracket 4, enabling the clamping mechanism 1 to flexibly adjust its position according to the detection needs, adapt to workpieces of different sizes or different positions, and improve the versatility and applicability of the device.

[0037] In some embodiments of the present invention, the bracket 4 also has a second driving motor 42, and the second driving motor 42 is used to drive the relative linear motion of the slider 12. Please continue to refer to Figures 1-3, driven by the second drive motor 42, the slider 12 can achieve automated linear motion on the slide rail 41. Compared with manual adjustment, the automated linear motion improves the operation efficiency and accuracy and reduces the need for manual intervention; the second drive motor 42 can precisely control the moving distance and speed of the slider 12 through the control system to achieve precise positioning of the clamping mechanism 1 on the slide rail 41. This is very important for tasks that require high-precision detection and helps to improve the accuracy and consistency of detection.

[0038] Furthermore, the clamping mechanism 1 further includes a connecting arm 13. A connecting sleeve 43 sleeved on the rotating shaft 31 is also provided on the bracket 4. One end of the connecting arm 13 is fixed to the rotating shaft 31, and the other end is fixed to the clamping jaw 11. Please continue to refer to Figures 1-3 , the connecting sleeve 43 is an annular or cylindrical component, sleeved outside the rotating shaft 31 and fixed to the bracket 4. The function of the connecting sleeve 43 is to provide additional support and stability for the rotating shaft 31 to ensure that the rotating shaft 31 remains stable during rotation without wobbling or offset; one end of the rotating shaft 31 is fixed to the connecting arm 13, so that the connecting arm 13 rotates synchronously with the rotating shaft 31. Through the connection of the connecting arm 13, the rotational motion is transmitted to the clamping jaw 11, thereby realizing the adjustment of the arrangement position of the wire harness terminals. Among them, the connecting arm 13 is of a two-section structure, and the two sections are connected by a rotating shaft. A limiting groove is also provided on the connecting arm 13, and there is a limiting block in the clamping mechanism 1 that matches the limiting groove to cooperate with it. When the relative position between the slider 12 in the clamping mechanism 1 and the slide rail 41 on the bracket 4 is zero, the length of the connecting arm 13 is compressed. At this time, due to the setting of the limiting groove and the limiting block, the clamping jaw 11 is in an open state; when the slider 12 has a relative displacement relative to the slide rail 41, the length of the connecting arm 13 is stretched. At this time, the clamping jaw 11 is naturally in a clamped state due to the sliding of the limiting block in the limiting groove. During this process, the connecting arm 13 directly connects the rotating shaft 31 and the clamping jaw 11, with a short transmission path and high efficiency, reducing the loss during power transmission, enabling the rotational motion to be efficiently transmitted to the clamping jaw 11, and realizing fast response and adjustment.

[0039] In some embodiments of the present invention, the imaging system 2 further includes an annular light source 22 and a housing 23. The annular light source 22 is installed in the housing 23. The rotating shaft 31 is hollowly arranged. The housing 23 is fixed to one end of the rotating shaft 31, and the other end of the housing 23 is fixed to the clamping jaw 11. As Figures 1-4As shown, the hollow rotating shaft 31 facilitates the installation position of the annular light source 22. The annular light source 22 can evenly irradiate the surface of the wire harness terminal to be detected, eliminating the shadows and uneven illumination caused by the position of the light source. This uniform illumination enables the imaging system 2 to capture the details of the workpiece more clearly, improving the quality of the image and the accuracy of detection. The housing 23 provides protection for the annular light source 22, enabling the close integration of the light source and the imaging system 2, saving additional installation space and simplifying the overall structural design.

[0040] More preferably, the clamping jaw 11 is further provided with a positioning mechanism 5. The positioning mechanism 5 includes a positioning jaw 51. The positioning mechanism 5 is fixed on the bracket 4, and the positioning jaw 51 is arranged in front of the clamping jaw 11. As Figure 5 、 Figure 6 shown, the positioning jaw 51 is specifically used to accurately position the wire harness terminal, ensuring that the wire harness terminal is in the correct position within the clamping jaw 11. The positioning jaw 51 provides additional support and fixing force during the clamping process, preventing the wire harness terminal from shifting or rotating during the detection process. By adding the positioning jaw 51, the clamping mechanism 1 can clamp the wire harness terminal more firmly. This structure reduces the risk of the wire harness terminal falling off or sliding, improving the safety and reliability of the operation. The clamping and releasing states of the positioning jaw 51 can be achieved by using an electric drive device or a pneumatic clamping device, etc.

[0041] Furthermore, the positioning mechanism 5 further includes a first lifting assembly 52, a first moving assembly 53, and a positioning driving member 54. The first lifting assembly 52 is installed on the bracket 4. One end of the positioning driving member 54 is connected to the first lifting assembly 52, and the other end is connected to the first moving assembly 53. Please continue to refer to Figure 5 and Figure 6 , the first lifting assembly 52 can use an electric linear push rod to achieve lifting. Driven by the positioning driving member 54, the positioning driving member 54 can be driven by an electric motor, etc., and can provide a stable lifting motion. Based on the push rod, the first moving assembly 53 is installed with a linear bearing system. The above method can also be achieved by a screw-driven lifting system, a sliding track, a linear guide rail, an electric elevator, etc. The clamping and releasing states of the positioning jaw 51 can be controlled by a clamping member arranged on the first moving platform to control the opening and closing size of the positioning jaw 51. The first lifting assembly 52 can accurately adjust the vertical position of the positioning jaw 51, so that the wire harness terminal can accurately enter the set position. The first moving assembly 53 can be adjusted in the horizontal direction, enabling the wire harness terminal to be accurately aligned within the clamping area. The first lifting assembly 52 and the first moving assembly 53 reduce the risk of unstable clamping or inaccurate detection caused by improper positions of the wire harness terminals by providing stable adjustment functions.

[0042] Specifically, a mobile vehicle 6 is further provided on the support 4. The mobile vehicle 6 includes a guiding jaw 61, and the guiding jaw 61 is arranged before the positioning jaw 51. As Figure 5 and Figure 7 shown, the mobile vehicle 6 is used to ensure that the guiding jaw 61 moves smoothly along a specified track or path, guiding the guiding jaw 61 to move in the correct direction, reducing the errors caused by unstable movement, thereby improving the accuracy of the overall system.

[0043] Based on the above embodiments, the mobile vehicle 6 further includes a second lifting assembly 62, a second moving assembly 63 and a guiding driving member 64. The positioning jaw 51 is arranged at one end of the second lifting assembly 62, the other end of the second lifting assembly 62 is connected to the guiding driving member 64, and the other end of the guiding driving member 64 is connected to the second moving assembly 63. Please continue to refer to Figure 5 and Figure 7 , the clamping and releasing states of the guiding jaw 61 can be directly controlled by the guiding driving motor 64 to control the opening and closing size. The principles and advantages of the second lifting assembly 62 and the second moving assembly 63 are the same as above, and will not be elaborated here.
