Description

Technical Field

[0001] The utility model relates to the technical field of label precision detection, and particularly to a device for inspecting the attachment precision of charger wire harness labels. Background Technique

[0002] Automobiles provide people with convenient and fast means of transportation. With the rapid development of new energy and its application in the automotive field, and with the popularization of new energy vehicles, charging of new energy vehicles has become a widespread and frequent phenomenon. During the production process of new energy vehicle chargers, labels are attached to the charging wires and some important information is marked on them. However, it is difficult to ensure that all labels are in the same position during the production process. The offset of the label position will not only damage the overall aesthetic coordination of the charger wire harness, but also cause some important information to be blocked or difficult to see clearly, increasing the risk of equipment damage or safety accidents. In view of this, we have proposed a device for inspecting the attachment precision of charger wire harness labels. Content of the Utility Model

[0003] The purpose of the utility model is to provide a device for inspecting the attachment precision of charger wire harness labels to solve the problems raised in the above background technique.

The housing includes a mounting frame. A fixing device is arranged on the upper side of the mounting frame, and the fixing device is used to fix both ends of the charger wire. An adjusting device is arranged under the fixing device, and the adjusting device is used to adjust the position of the fixing device. The adjusting device includes a bidirectional threaded screw rod. A screw rod sleeve is threadedly connected to the outer side of the bidirectional threaded screw rod, and one end of the bidirectional threaded screw rod is fixedly connected to a driving motor.

[0022] Embodiment 1

[0023] Please refer to Figures 1 - 3As shown in the figure, this embodiment provides a charger wire harness label attachment accuracy inspection device, including a housing 1. The housing 1 includes a mounting frame 11. A lead screw groove 12 is formed on the upper surface of the mounting frame 11. A scale line 13 is provided on the upper surface of the mounting frame 11 on one side of the lead screw groove 12. When the wire is tightened, the position of the label can be seen by observing the scale value where the label is located, so as to determine whether the position of the label has shifted. A fixing device 3 is arranged above the mounting frame 11. The fixing device 3 is used to fix both ends of the charger wire. An adjusting device 2 is arranged below the fixing device 3. The adjusting device 2 is used to adjust the position of the fixing device 3. The adjusting device 2 includes a bidirectional lead screw 21. The bidirectional lead screw 21 is rotatably arranged inside the lead screw groove 12. A lead screw sleeve 22 is threadedly connected to the outside of the bidirectional lead screw 21. A driving motor 23 is fixedly installed on one side of the mounting frame 11. The output shaft of the driving motor 23 penetrates the mounting frame 11 and is fixedly connected to the bidirectional lead screw 21. By driving the bidirectional lead screw 21 to rotate by the driving motor 23, the two lead screw sleeves 22 threadedly connected to the bidirectional lead screw 21 move, thereby tightening the wire to make the detection of the label position more accurate.

[0024] Please refer to Figure Figure 4 As shown in the figure, a T-shaped sliding groove 4 is formed on the upper surface of the lead screw sleeve 22. A T-shaped slider 5 is slidably arranged inside the T-shaped sliding groove 4. A buffer spring 6 is fixedly installed inside the T-shaped sliding groove 4. The other end of the buffer spring 6 is fixedly installed on the side of the T-shaped slider 5 close to the center of the bidirectional lead screw 21. When the wire is tightened, through the setting of the buffer spring 6, the pulling force of the fixing device 3 on the wire is buffered, avoiding damage to the wire caused by the influence of the pulling force after the wire is tightened, and playing a protective role for the wire.

[0025] Please refer to Figure 5 As shown in the figure, the fixing device 3 includes a fixing sleeve 31 and a fixing clip 32 arranged inside the fixing sleeve 31. The fixing clip 32 is provided with a through hole 33. A connecting rod 34 is fixedly arranged inside the fixing sleeve 31. The connecting rod 34 penetrates the through hole 33. Two fixing springs 35 are sleeved outside the connecting rod 34. The fixing springs 35 are located between the fixing clip 32 and the inner wall of the fixing sleeve 31. The elastic thrust applied by the fixing springs 35 to the fixing clip 32 makes the fixing clip 32 clamp, thereby forming a closed annular space, avoiding falling off when the wire is tightened, and at the same time preventing the wire from popping out and injuring the staff in the tight state. A triangular block 36 is fixedly connected to the upper side of the T-shaped slider 5. The top edge of the triangular block 36 is located between the two branches of the fixing clip 32. When the fixing sleeve 31 is pressed down, the fixing clip 32 is opened by the support of the inclined surface of the triangular block 36 on the fixing clip 32, facilitating the wire to be put into the fixing clip 32 and clamped, and the operation is convenient.

[0026] Please refer to Figure 6As shown, a limit sleeve 37 is fixedly connected to the upper side of the T-shaped slider 5. A limit groove 38 is formed inside the limit sleeve 37. A limit block 39 is slidably arranged inside the limit groove 38. The limit block 39 is fixedly arranged on the fixed sleeve 31. When the fixed sleeve 31 slides inside the limit sleeve 37, the position of the fixed sleeve 31 is limited and guided by the sliding of the limit block 39 inside the limit groove 38, preventing the fixed sleeve 31 from slipping off.

[0027] When the charger wire harness label attachment accuracy inspection device of this embodiment is specifically used, the user first presses down the fixed sleeve 31 to open the fixed clip 32 inside the fixed sleeve 31, puts the two ends of the wire into the fixed clip 32 and then releases it. The elastic thrust applied by the fixed spring 35 to the fixed clip 32 makes the fixed clip 32 clamp and form an annular sealed space, preventing the charging wire from falling off during the process of pulling and tightening the wire. Then, the driving motor 23 is turned on to drive the two screw sleeves 22 to move by the bidirectional threaded lead screw 21, thereby tightening the wire. When the wire is straightened, it can be determined whether the label has shifted by comparing the scale numbers where the label is located.

[0028] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and are not used to limit the present invention.
