Description

Technical Field

[0001] The utility model relates to the technical field of wire harness detection, in particular to a wire harness terminal pull-off force and color detection device. Background Art

[0002] Wiring harnesses play a vital role as key electrical equipment for automobile signal transmission and vehicle power supply. Therefore, they need to be tested before leaving the factory to ensure product quality. When testing the wiring harnesses, it is necessary to check the pull-off force of the crimped terminals and the colors of the wiring harnesses, including red and blue, to avoid incorrect installation and ensure factory quality.

[0003] However, the testing instruments currently used have complex structures and high costs, and cannot meet production needs. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a wiring harness terminal pull-off force and color detection device that can improve detection efficiency, is low-cost, and is easy to use.

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] A wire harness terminal pull-off force and color detection device, comprising a workbench, wherein a terminal feeding structure and a detection structure are arranged on the workbench;

[0007] The detection structure includes a base fixedly mounted on a workbench through a bracket, a floating base fixedly mounted on the base, a pull-off force detection component connected to the floating base, a slide groove provided on the floating base, a terminal slide slidably fitted in the slide groove, a terminal slide provided with a terminal slot, a makeshift slot for allowing the terminal to pass through provided on the floating base, a sliding component for driving the terminal slide to slide along the slide groove provided on the base; a cover plate fixedly mounted on the floating base, a detection port provided on one side of the floating base, a lower end height of the detection port being higher than a lower end height of the terminal slot and lower than a height of a plug in the terminal slot; a wire harness color detection component is installed on the base.

[0008] In this way, the terminal is loaded through the wire harness loading structure, and the terminal reaches the terminal slot of the terminal slide through the clearance slot. The sliding component pushes the terminal slide to slide along the slide slot to the detection port position, and the operator inserts the wire harness into the terminal socket. The wire harness is provided with two wires of different colors. After the wire harness is inserted, the wire harness is clamped with the terminal. Then the operator pulls the wire harness, thereby driving the floating base to float. The pull-off force detection component detects the pull-off force of the floating base during the floating process. After the pull-off force is qualified, the operator releases the wire harness and then performs a pull-off force test on another wire harness. After the two wire harnesses are connected to the terminal, the pull-off force is qualified. The wire harness color detection component automatically detects the colors of the two wire harnesses. After the color detection is completed, the sliding component continues to drive the terminal slide to move along the slide slot until the terminal slot moves to the outside of the floating base. The operator removes the wire harness and the terminal to complete the detection. Due to the setting of the cover plate, during the detection process, the terminal is prevented from being separated from the terminal slide, thereby improving the stability and reliability of the detection process.

[0023] The present invention will be further described in detail below with reference to the drawings. In the description of the present invention, it should be understood that the orientation or positional relationship indicated by orientation words such as "upper, lower" and "top, bottom" is usually based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present invention and simplifying the description. Without contrary description, these orientation words do not indicate and imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as a limitation on the protection scope of the present invention; the orientation words "inner, outer" refer to the inside and outside relative to the contour of each component itself.

[0024] As Figures 1-4 shown, a wire harness terminal pull-off force and color detection device includes a workbench 1, and a terminal feeding structure 2 and a detection structure are arranged on the workbench;

[0025] The detection structure includes a base 4 fixedly installed on the workbench through a bracket 3. A floating base 5 is fixedly installed on the base. The floating base is connected with a pull-off force detection component. A chute is formed on the floating base, and a terminal slide 6 is slidably fitted in the chute. A terminal groove is formed in the terminal slide. A relief groove allowing a terminal 7 to pass through is formed in the floating base. A sliding component for driving the terminal slide to slide along the chute is installed on the base. A cover plate 8 is fixedly installed on the floating base. A detection port is formed on one side of the floating base. The height of the lower end of the detection port is higher than the height of the lower end of the terminal groove and less than the height of the insertion port 9 of the terminal groove. A wire harness color detection component is installed on the base.

[0026] In this way, the terminal is loaded by the wire harness loading structure. The terminal reaches the terminal groove of the terminal slide through the relief groove. The sliding component pushes the terminal slide to slide along the chute to the position of the detection port. The operator inserts the wire harness into the insertion port of the terminal. There are two wire harnesses with different colors. After the wire harness is inserted, the wire harness is clamped with the terminal. Then the operator pulls the wire harness. Since the height of the lower end of the detection port is higher than the height of the lower end of the terminal groove, it can prevent the terminal from detaching from the terminal slide, thereby driving the floating base to float. The pull-off force detection component detects the pull-off force during the floating process of the floating base. After the pull-off force is qualified, the operator releases the wire harness, and then performs the pull-off force detection on the other wire harness. After the two wire harnesses are connected to the terminal and the pull-off force is qualified, the wire harness color detection component automatically detects the colors of the two wire harnesses. After the color detection is completed, the sliding component continues to drive the terminal slide to move along the chute until the terminal groove moves to the outside of the floating base. The operator removes the wire harness and the terminal to complete the detection. Due to the setting of the cover plate, during the detection process, the terminal is prevented from detaching from the terminal slide, improving the stability and reliability of the detection process.

[0027] During implementation, the terminal loading structure includes a vibrating bowl fixedly installed on the workbench. A linear vibrator is arranged at the discharge port of the vibrating bowl. A linear guide rail is installed at the upper end of the linear vibrator. A terminal guide groove is formed in the linear guide rail. One end of the linear guide rail extends to the relief groove of the floating base. Through the vibrating bowl and the linear vibrator, the terminal is automatically loaded, improving the detection efficiency. The size of the relief groove is larger than the size of the linear guide rail, facilitating the floating of the floating base. The terminal loading structure is an existing structure.

[0028] During implementation, the floating base is provided with an oval hole 11. A screw (not shown) is threadedly connected to the base, and the screw is located in the oval hole. This facilitates the floating of the floating base.

[0029] During implementation, the pulling force detection component includes a pulling force sensor 12 and a tension spring 13. The detection end of the pulling force sensor is fixedly connected to the floating base. The pulling force sensor is fixedly installed on the base through a pulling force seat. A connecting pin 14 is fixed on the floating base. One end of the tension spring is connected to the connecting pin, and the other end of the tension spring is fixedly connected to the base through a mounting seat. An operator pulls the wire harness, and the pulling force is transmitted to the floating base. The floating base floats, and the pulling force during the floating process of the floating base is detected by the pulling force sensor. When the pulling force reaches the detection value and the wire harness does not disengage from the terminal, the pulling force is qualified. When the wire harness is released, under the action of the tension spring, the floating slide is driven to reset.

[0030] Specifically, it further includes a controller and a display screen. The pulling force sensor is connected to the controller and an alarm. When the pulling force sensor detects a predetermined pulling force, the alarm emits a beeping sound. When the operator releases the wire harness and the wire harness does not disengage from the terminal, the pulling force between the wire harness and the terminal is qualified. The magnitude of the pulling force can be displayed through the display screen.

[0031] During implementation, sliding rails 15 protrude inwardly on both sides of the chute, and the terminal slide is provided with sliding openings 16 that are slidably engaged with the sliding rails. This facilitates guiding the sliding of the terminal slide.

[0032] During implementation, the sliding component includes a driving cylinder 17 fixedly installed on the base. The cylinder rod of the driving cylinder is connected to the terminal slide through a cylinder swing floating joint 18. The driving cylinder is connected to the terminal slide through the cylinder swing floating joint, which can drive the terminal slide to move and can cooperate with the swing of the floating base.

[0033] During implementation, the cover plate is bent downward to form a guide plate 19, and the upper end of the terminal slide is provided with a guide groove 20 that is slidably engaged with the guide plate. This facilitates guiding the terminal slide. The guide plate is arranged opposite to the notch of the terminal, which is convenient for blocking the terminal.

[0034] During implementation, the wire harness color detection component includes two chromatographic sensors 21. The chromatographic sensors are fixedly installed on the base and the detection ends are arranged upward. It has low cost and can detect the color of the wire harness more quickly. The chromatographic sensors are connected to the controller.

[0035] During implementation, a positioning cylinder 22 is fixedly installed on the base through a cylinder seat. A positioning block 23 is fixedly installed on the cylinder rod of the positioning cylinder. The positioning block is arranged opposite to the terminal slide. Through the setting of the positioning cylinder, after the detection is completed, the positioning cylinder drives the positioning block to move, pushing the terminal slide to reset, so that the terminal groove is aligned with the linear guide rail, which is convenient for terminal feeding.

[0036] During implementation, a casing 24 is fixedly installed on the workbench. The casing is arranged outside the detection structure, and a detection position is provided on the casing. This improves the integrity.

[0037] Finally, it should be noted that those skilled in the art can make various modifications and variations to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalents, the present utility model is also intended to cover these modifications and variations.
