Description

Technical Field

[0001] This utility model relates to the field of wire harness inspection technology, and in particular to a visual inspection device for red and black tape. Background Technology

[0002] In existing high-current, high-voltage wire harness production processes, red and black tape are typically used to mark the wire harnesses. Red tape indicates the positive terminal of the connector, and black tape indicates the negative terminal. However, current inspection of the red and black tape relies primarily on manual visual inspection to distinguish the tape colors. This manual visual inspection method has the following problems: 1. High risk of human error: Prolonged work can easily lead to fatigue, resulting in incorrect tape application and affecting product quality. 2. Low efficiency: Manual inspection is slow and cannot meet the needs of large-scale production. Therefore, it is necessary to develop a visual inspection device for red and black tape in wire harnesses to achieve accurate and efficient inspection. Utility Model Content

[0003] To address the shortcomings in the aforementioned background technology, this utility model proposes a visual inspection device for red and black tape used in high-current high-voltage wiring harnesses, which solves the problems of easy errors and low efficiency in manual visual inspection in the prior art.

[0004] The technical solution of this utility model is implemented as follows: A visual inspection device for red and black tape used in high-current, high-voltage wire harnesses includes a base, on which are a left support and a right support with adjustable relative positions. A positioning seat is provided between the left and right supports, and the positioning seat is detachably mounted on the base. A black tape detection sensor is installed in the left support, and a red tape detection sensor is installed in the right support. By automatically identifying colors through sensors, errors caused by human factors are avoided, significantly improving the accuracy and stability of color recognition.

[0005] Further preferably, the high-current, high-voltage wire harness visual inspection device with red and black tape also includes a connector holder and a wire harness positioning clip. The connector holder is located on one side of the base, and the wire harness positioning clip is located on the other side of the base. The connector holder and the wire harness positioning clip respectively position the connector and the wire harness, ensuring that the red and black tape portion on the wire harness is accurately positioned in the inspection area.

[0006] Further preferably, the base is a stepped base, with a slot in the middle that matches the positioning seat. The upper part of the stepped base has an X-shaped elongated through hole and a Z-shaped power supply hole. The X-shaped elongated through hole is used for adjusting and fixing the positions of the left and right supports. The Z-shaped power supply hole is used for connecting an external charging cable.

[0007] Further preferably, both the left and right supports are box-shaped seats with openings on one side. The bottom of the box-shaped seat has a limiting groove that mates with the higher-level boss of the stepped seat. An X-axis threaded hole is provided on the side wall of the limiting groove. A bolt threaded to the X-axis threaded hole mates with an X-axis elongated through hole, fixing the box-shaped seat to the base. The bolt passes through the X-axis elongated through hole and is threaded to the X-axis threaded hole, which can both adjust the position of the box-shaped seat in the X-axis direction and fix it in a suitable position. This testing fixture can adapt to various production environments and tapes of different specifications of wire harnesses.

[0008] Further preferably, the box-shaped base is internally divided into an alarm chamber and a detection chamber by a partition. The alarm chamber houses an audible and visual alarm and a controller. A black adhesive detection sensor is located in the detection chamber of the left support, and a red adhesive detection sensor is located in the detection chamber of the right support. Both the black adhesive detection sensor and its corresponding audible and visual alarm are connected to their respective controllers. The two color recognition sensors detect the color of the adhesive tape, and the audible and visual alarms alert the operator whether the tape color has been incorrectly applied.

[0009] In a further preferred embodiment, both the black glue detection sensor and the red glue detection sensor are color sensors. The left support has a left detection hole on the side corresponding to the positioning seat, and the right support has a right detection hole on the side corresponding to the positioning seat. The detection port of the black glue detection sensor corresponds to the left detection hole, and the red glue detection sensor corresponds to the right detection hole, ensuring the accuracy of the detection position.

[0010] In a further preferred embodiment, the positioning seat includes an upper pad and a lower pad. The upper pad, the lower pad, and the base are all provided with corresponding threaded holes. The upper pad is located on the upper part of the base, and the lower pad is located on the lower part of the base. The upper pad and the lower pad are fixed to the base by long bolts that match the threaded holes.

[0011] Further preferably, the base has a positioning groove at the bottom, the lower pad is located in the positioning groove and is flush with the bottom surface of the base, and the base also has an anti-slip pad at the bottom.

[0012] Furthermore, the base is also equipped with supplementary lights. These supplementary lights are located on both sides of the positioning base; in low-light conditions, they can provide supplementary illumination to ensure accurate and reliable detection.

[0013] The beneficial effects of this invention are as follows: This invention uses two detection sensors on the left and right sides to simultaneously detect the red and black tape portions of two wire harnesses, avoiding errors caused by human factors and significantly improving the accuracy and stability of color recognition. Furthermore, the detection sensors, used in conjunction with an audible and visual alarm, greatly improve production efficiency and reduce rework time caused by color errors.

[0014] This invention features adjustable left and right supports relative to the base, allowing for adjustment of the distance between the detection sensor and the wire harness tape. Furthermore, the wire harness height can be adjusted using different positioning seats. These two adjustable distance functions enable the fixture to adapt to various production environments and different specifications of wire harness tape for detection, improving the device's applicability. In addition, this invention has a compact design and high integration, making it suitable for placement in confined spaces; its wiring is also simple and rational, facilitating 5S management.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1As shown in Embodiment 1, a visual inspection device for red and black tape used in high-current, high-voltage wire harnesses includes a base 1. The base 1 has a left support 2 and a right support 3 with adjustable relative positions; that is, the left and right supports can move relative to the base to adjust the distance between them to accommodate the inspection of red and black tape of different specifications. A positioning seat 4 is provided between the left support 2 and the right support 3 to support and position the wire harness, ensuring the red and black tape on the harness is at the detection point. The positioning seat 4 is detachably mounted on the base 1, and a suitable positioning seat can be selected according to the different specifications of the red and black tape. A black tape detection sensor 5 is installed in the left support 2, and a red tape detection sensor 6 is installed in the right support 3. The black tape detection sensor 5 is used to detect whether the black tape is correctly wound, and the red tape detection sensor 6 is used to detect whether the red tape is correctly wound. Automatic color recognition by sensors avoids errors caused by human factors and significantly improves the accuracy and stability of color recognition.

[0023] like Figure 2 As shown in Embodiment 2, a visual inspection device for red and black tape used in high-current, high-voltage wire harnesses includes a base 1. The base 1 has a left support 2 and a right support 3 with adjustable relative positions; that is, the left and right supports can move relative to the base to adjust the distance between them to accommodate the inspection of red and black tape of different specifications. A positioning seat 4 is provided between the left support 2 and the right support 3 to support and position the wire harness, ensuring the red and black tape on the harness is at the detection point. The positioning seat 4 is detachably mounted on the base 1, and a suitable positioning seat can be selected according to the different specifications of the red and black tape. A black tape detection sensor 5 is installed in the left support 2, and a red tape detection sensor 6 is installed in the right support 3. The black tape detection sensor 5 is used to detect whether the black tape is correctly wound, and the red tape detection sensor 6 is used to detect whether the red tape is correctly wound. Automatic color recognition by sensors avoids errors caused by human factors and significantly improves the accuracy and stability of color recognition. The aforementioned high-current, high-voltage wire harness visual inspection device with red and black tape further includes a connector mounting base 7 and a wire harness positioning clip 8. The connector mounting base 7 is located on one side of the base 1, and the wire harness positioning clip 8 is located on the other side of the base 1. The connector mounting base and the wire harness positioning clip respectively position the connector and the wire harness, placing the red and black tape portion of the wire harness on the positioning base 4, while positioning the front and rear ends of the red and black tape portion to ensure that the red and black tape portion is accurately positioned in the detection area between the black tape detection sensor 5 and the red tape detection sensor 6, thereby improving detection accuracy and efficiency.

[0024] like Figure 3As shown, in this embodiment, the base 1 is a stepped base with a two-tiered structure. The middle of the stepped base has a slot 11 that matches the positioning seat 4, used to limit the positioning seat. The higher-level protrusion of the stepped base has an X-axis elongated through-hole 12 and a Z-axis power supply hole 13. The X-axis elongated through-hole 12 is used for adjusting and fixing the positions of the left and right supports. The Z-axis power supply hole 13 is used to connect an external charging cable to power the corresponding electrical components of the visual inspection device, such as the controller, supplementary light, and sensors.

[0025] like Figure 4 As shown, in this embodiment, both the left support 2 and the right support 3 are box-shaped seats with openings on one side. The bottom of the box-shaped seat is provided with a limiting groove 21 that mates with the high-level boss of the stepped seat. An X-direction threaded hole 22 is provided on the side wall of the limiting groove 21. A bolt 23, which is threaded to the X-direction threaded hole 22, mates with the X-direction elongated through hole 12 and fixes the box-shaped seat on the base 1. The bolt passes through the X-direction elongated through hole and is threaded to the X-direction threaded hole, which can both adjust the position of the box-shaped seat in the X direction and fix it in a suitable position. In this way, the testing fixture can adapt to various production environments and tapes of different specifications of wire harnesses.

[0026] In this embodiment, the box-shaped base is divided into an alarm chamber and a detection chamber by a partition 24. The alarm chamber contains an audible and visual alarm 9 and a controller. A black adhesive detection sensor 5 is located in the detection chamber of the left support 2, and a red adhesive detection sensor 6 is located in the detection chamber of the right support 3. The black adhesive detection sensor 5 and the audible and visual alarm 9 in the left support 2 are both connected to their respective controllers. The color signals collected by the black and red adhesive detection sensors are transmitted to their respective controllers. When a detection sensor detects an error in the tape color, the controller activates the corresponding audible and visual alarm 9 to alert the staff for timely handling. The automatic detection and alarm functions greatly improve production efficiency and reduce rework time caused by color errors.

[0027] In this embodiment, both the black adhesive detection sensor 5 and the red adhesive detection sensor 6 are color sensors. The color sensors can be monochrome color sensors, whose preset color thresholds have been verified through extensive experimentation to ensure accurate differentiation between red and black under different lighting conditions; alternatively, RGB color sensors, such as the Panasonic LX101PZ color sensor, can be used. The left support 2 has a left detection hole 25 on the side corresponding to the positioning seat 4, and the right support 3 has a right detection hole 26 on the side corresponding to the positioning seat 4. The detection port of the black adhesive detection sensor 5 corresponds to the left detection hole 25, and the red adhesive detection sensor 6 corresponds to the right detection hole 26. The placement of the detection holes ensures both the correct sensor mounting position and accurate detection of the wire harness tape portion on the positioning seat.

[0028] like Figure 5 As shown in Embodiment 3, a visual inspection device for red and black tape used in high-current high-voltage wire harnesses, based on Embodiments 1 or 2, includes an upper pad 41 and a lower pad 42 on the positioning base 4. The upper pad 41, lower pad 42, and base 1 are all provided with corresponding threaded holes 43. The upper pad 41 is positioned on the upper part of the base 1, and the lower pad 42 is positioned on the lower part of the base 1. The upper pad 41 and lower pad 42 are fixed to the base 1 by long bolts 44 that match the threaded holes 43. The bottom of the base 1 is provided with a positioning groove 14. In practical use, the upper pad is placed in the slot 11, the lower pad 42 is placed in the positioning groove 14, and then a long bolt is used to sequentially pass through the upper pad, base, and lower pad to achieve connection and fixation between the three. The threaded holes can also be open holes, and the long bolts are fixed with nuts. The function of the upper pad is to adjust the support for the wire harness tape, ensuring that when placed on the upper pad, the wire harness tape is flush with the detection head of the detection sensor, thus ensuring detection accuracy. The lower pad 42 is located within the positioning groove 14 and is basically flush with the bottom surface of the base 1. The lower pad is used to fix the upper pad and is also made of insulating anti-slip pad, which, together with the anti-slip pad 15 provided at the bottom of the base 1, ensures the stability of the base when it is placed on the operating platform. The upper pad of different thicknesses can be replaced according to different wire harnesses to quickly adapt to different wire harnesses.

[0029] As an alternative, a supplementary light 16 can also be embedded in the base 1. The supplementary light 16 is located on both sides of the positioning seat 4 and corresponds to the tape portion of the two wire harnesses. When the light is dim, the supplementary light can provide supplementary lighting to ensure accurate and reliable detection.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
