[0032] See also Figures 1 to 3 It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the utility model, and the drawings only show the components related to the utility model rather than the number, shape and size of the components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0033] The utility model provides a connector insulator direction detection device, specifically as follows Figure 1 As shown, the insulator 10 is cylindrical, and an annular groove 100 is provided on the circumference of the insulator 10. The annular groove 100 divides the insulator 10 into a first segment 101 and a second segment 102. Specifically, the length of the first segment 101 is less than the length of the second segment 102. Figure 2 As shown, the detection device includes a base 20, a fixed tool 30, a positioning tool 301, a visual inspection module 40 and a PLC control unit (not shown in the figure), wherein the fixed tool 30 is arranged on the base 20, the fixed tool 30 includes a cylinder 31 and a clamp 32 connected to the cylinder 31, the cylinder 31 is used to drive the clamp 32 to open and close, the clamp 32 is used to clamp and fix the positioning tool 301, and the positioning tool 301 is used to place the insulator 10; the visual inspection module 40 is arranged on the base 10, and the visual inspection module 40 is used to obtain the position of the insulator 10 placed on the positioning tool The image information of the insulator 10 on the tool 301 is obtained by analyzing and judging the image information to obtain detection information. Specifically, the detection information includes whether the insulator 10 is placed with the first segment 101 facing upward or the insulator 10 is placed with the second segment 102 facing upward. The PLC control unit is connected to the cylinder 31 and the visual inspection module 40, and the PLC control unit is used to receive the detection information. When the detection information received by the PLC control unit is that the insulator 10 is placed with the first segment 101 facing upward, the PLC control unit controls the cylinder 31 to drive the clamp 32 to open.

[0034] When the connector insulator direction detection device of the utility model is in use, the operator first fixes the insulator 10 on the positioning tool 301, and then clamps the positioning tool 301 by the clamp 32, and the visual detection module 40 obtains the image information of the insulator placed on the positioning tool 301, and the visual detection module 40 analyzes and determines the detection information based on the image information, that is, analyzes and determines whether the insulator is placed on the positioning tool 301 with the first segment 101 facing upward (correct direction) or placed on the positioning tool 301 with the second segment 102 facing upward (wrong direction), and then transmits the detection information to the PLC control unit. When the detection information received by the PLC control unit is that the insulator 10 is placed with the first segment 101 facing upward (that is, when the placement direction is correct), the PLC control unit controls the cylinder 31 to drive the clamp 32 to open, and the operator can remove the positioning tool 301 with the insulator as a whole, and then assemble the insulator into the connector in the correct direction. Compared with the prior art in which the assembly direction of the insulator is manually determined, the connector insulator direction detection device of the utility model can greatly improve the accuracy of insulator direction determination, avoid the risk of human determination errors, improve product assembly yield, and ensure product quality.

[0035] Specifically, in this embodiment, the visual inspection module 40 can perform a size inspection on the upper segment of the insulator placed on the positioning tool 301 to analyze and determine whether the direction of the insulator placement is correct, that is, because the length of the first segment 101 is smaller than the length of the second segment 102, the visual inspection module performs a size inspection on the upper segment in the image information of the obtained insulator, and compares the obtained size data with the preset value. If the detected size data is the same as the preset value or within a reasonable deviation, it is determined that the direction of the insulator placement is correct; if the detected size data is larger than the preset value, it is determined that the placement direction of the insulator is wrong. Specifically, in this embodiment, the length of the first segment 101 is 286-287mm, and the length of the second segment 102 is 345-346mm.

[0036] Furthermore, in this embodiment, the visual inspection module 40 is arranged on the base 20 in a height-adjustable manner in the vertical direction. Through this structural design, the inspection device can be applied to insulator products of different heights, thereby improving the applicability of the inspection device.

[0037] Specifically, Figure 2 As shown, in this embodiment, the visual inspection module 40 is arranged on the base 20 through a mounting plate 41, and the mounting plate 41 is provided with a long hole 411 extending in the vertical direction, and the visual inspection module 40 is connected to the long hole 411 on the mounting plate 41 through a bolt. Through this structural design, when it is necessary to adjust the height of the visual inspection module 40, the bolt is loosened, so that the visual inspection module 40 can move in the vertical direction along the long hole 411, and when it is adjusted to a suitable height, the bolt is tightened to fix the visual inspection module 40, which is simple to operate, convenient to adjust, simple in structure, and low in cost.

[0038] Specifically, in this embodiment, the visual detection module 40 includes a camera.

[0039] Furthermore, in order to make the image information of the insulator obtained by the visual inspection module 40 clearer, preferably, in this embodiment, an auxiliary light source is further provided on one side of the base 20, and the auxiliary light source is arranged opposite to the visual inspection module 40. Through this structural design, the background color of the obtained image information can be made white, while the image information of the insulator is black, so that the image information can be better analyzed and judged.

[0040] Furthermore, in the present embodiment, a protective cover 200 is provided on the base 20 , and the protective cover 200 is used to protect the visual inspection module 40 and the fixed tooling 20 , thereby avoiding the influence and interference of external factors on the inspection and improving the accuracy of the inspection.

[0041] Specifically, Figure 3 As shown, the connector insulator direction detection device can be placed on a working platform 300 for use according to specific needs.

[0042] In summary, the connector insulator direction detection device of the utility model greatly improves the accuracy of insulator direction identification, avoids the risk of human error in identification, effectively improves the product assembly yield, and the detection device can be used for error prevention of various aviation connector parts installation. Therefore, the utility model effectively overcomes various shortcomings in the prior art and has a high industrial utilization value.
