[0028] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5A continuous detection mechanism for detecting lateral tension of a wiring harness is shown, comprising a horizontal main frame 1, an upper electrically controlled conveyor belt 2 and a lower electrically controlled conveyor belt 3 installed on the horizontal main frame 1, electrically controlled feeding boxes 4 are movably installed above the upper electrically controlled conveyor belt 2 and the lower electrically controlled conveyor belt 3 on the horizontal main frame 1, three electrically controlled translationally adjustable tension paddles 5 are installed on both sides of the upper electrically controlled conveyor belt 2 and the lower electrically controlled conveyor belt 3 inside the horizontal main frame 1, lateral assembly seats 6 matched with the electrically controlled translationally adjustable tension paddles 5 are elastically installed at both ends of the inner sides of the upper electrically controlled conveyor belt 2 and the lower electrically controlled conveyor belt 3, and optical recognition modules 7 are fixedly installed above the upper electrically controlled conveyor belt 2 and the lower electrically controlled conveyor belt 3 on the horizontal main frame 1.

[0031] Working principle: People pre-load the wire harnesses layer by layer into the electric control feeding box 4, and then guide the wire harnesses one by one to the upper electric control conveyor belt 2 through the electric control feeding box 4. As the upper electric control conveyor belt 2 is driven, the curved guide rails formed by the electric control translation adjustment tension paddles 5 on both sides control the lateral assembly seats 6 on both sides of the upper electric control conveyor belt 2 to squeeze to both sides during the translation process, so as to measure the tensile force of the terminals on both sides of the wire harness. At the discharge port, the optical recognition module 7 uses optical recognition technology to identify the tightness of the wire harness, and judges whether there is a fault by the curvature of the wire harness. Once a fault occurs, the electric control translation adjustment tension paddle 5 of the discharge port is controlled to extend to the inner side of the upper electric control conveyor belt 2, so as to be elastically reset through the lateral assembly seat 6 and fall by the gravity of the wire harness itself; when the upper electric control conveyor belt 2 is detected correctly, the wire harness is driven to move to the upper electric control conveyor belt 2 and the lower electric control conveyor belt 3. The electric control feeding box 4 between them, in the same way as above, uses the electric control translation adjustment tension paddle 5 to extend to the inner side of the upper electric control conveyor belt 2, so that it is elastically reset through the lateral assembly seat 6, and the wire harness itself falls onto the electric control feeding box 4, and then the electric control feeding box 4 is used to guide the wire harness one by one to the lower electric control conveyor belt 3. As the lower electric control conveyor belt 3 is driven, the curved guide rails formed by the electric control translation adjustment tension paddles 5 on both sides control the lateral assembly seats 6 on both sides of the upper electric control conveyor belt 2 to be squeezed to both sides during the translation process. At the discharge port position, the optical recognition module 7 uses optical recognition technology to identify the tightness of the wire harness, and determines whether there is a fault by the curvature of the wire harness. Once a fault occurs, the electric control translation adjustment tension paddle 5 of the discharge port is controlled to extend to the inner side of the lower electric control conveyor belt 3, so that it is elastically reset through the lateral assembly seat 6, and the wire harness itself falls.

[0032] In order to cooperate with the electric control material feeding, the upper electric control material feeding belt 2 and the lower electric control material feeding belt 3 both include a main driving roller 231 movably installed inside the transmission groove at the upper end of the horizontal main frame 1, an auxiliary support roller 232, a flexible conveyor belt 233 and an external conveyor plate 234 installed on the outside of the flexible conveyor belt 233.

[0033] The main driving roller 231 rotates to drive the flexible conveying belt 233 to adjust along the auxiliary supporting roller 232, and then synchronously drives the external book material plate 234 to adjust and convey.

[0034] In order to cooperate with height and angle adjustment, the electric control feeding box 4 includes an external flip frame 41 movably installed on the outside of the horizontal main frame 1, an outer adjustment strut 42 for controlling the flipping of the external flip frame 41, an internal electric control material guide box 43 movably installed inside the external flip frame 41 and an inner adjustment strut 44 for controlling the internal electric control material guide box 43.

[0035] The angle of the external flip frame 41 is changed by extending and retracting the external adjustment strut 42, thereby changing the height of the internal electric-controlled material guide box 43, and the angle of the internal electric-controlled material guide box 43 is changed by extending and retracting the internal adjustment strut 44.

[0036] By lowering the height and angle of the internal electrically-controlled material guide box 43, it is convenient for people to guide the wire harness into the interior at a low position, thereby facilitating material loading.

[0037] In order to cooperate with the external material guiding, the internal electrically controlled material guiding box 43 includes a material guiding box body 431 axially movably installed inside the external flip frame 41, an electrically controlled material guiding belt 432 movably installed on both sides of the material guiding box body 431, and an L-shaped outer limiting frame 433 installed outside the electrically controlled material guiding belt 432.

[0038] The two ends of the wiring harness are respectively sleeved on the outer limit frames 433 at the two ends, and are transported downward through the electrically controlled material guide belt 432, thereby driving the wiring harness to be introduced into the lateral assembly seat 6 on the upper electrically controlled material conveyor belt 2 or the lower electrically controlled material conveyor belt 3.

[0039] In order to cooperate with the inner sliding adjustment, the lateral assembly seat 6 includes an outer guide rail 61 fixedly installed on both sides of the inner wall of the outer feed plate 234, an L-shaped outer assembly frame 62 slidably assembled inside the outer guide rail 61, and a side spring 63 installed inside the outer guide rail 61. The outer assembly frame 62 is inserted into the side spring 63 through the inner extrusion rod 64 and elastically extruded by the side spring 63.

[0040] In order to guide and extrude the two ends of the wire harness, the electrically controlled translational tension adjustment paddle 5 includes a transverse electrically controlled support rod 51 fixed inside the horizontal main frame 1 and a curved material guide frame 52 axially fixed to the protruding end of the transverse electrically controlled support rod 51 .

[0041] The horizontally placed electrically controlled support rod 51 controls the translation of the curved material guide frame 52 inside the upper electrically controlled material conveyor belt 2 or the lower electrically controlled material conveyor belt 3 by telescoping, thereby controlling the application of gradually increasing pulling force to both ends of the wire harness at different positions, so as to gradually test the pulling force of the wire harness, and set the maximum pulling force by setting the telescopic distance.

[0042] When the curved material guide frame 52 moves outward, the bottom side end of the outer assembly frame 62 is guided and extruded.

[0043] In order to monitor the pressure of the pulling surface, a pressure sensor 65 is fixedly mounted on the side wall of the outer assembly frame 62 .

[0044] By monitoring the pressure at different positions, the tensile strength of the wiring harness at different positions can be measured in real time.

[0045] In order to cooperate with installation monitoring, the optical recognition module 7 includes an upper assembly frame 71 of a Y-shaped structure fixedly installed on the upper end of the horizontal main frame 1 and a first optical recognition module 72 and a second optical recognition module 73 fixedly installed on the top surface of the upper assembly frame 71.

[0046] The first optical recognition module 72 and the second optical recognition module 73 detect the straightness of the wire harness through optical detection. Once the wire harness is bent, it indicates that the wire harness is faulty.

[0047] When the first optical recognition module 72 or the second optical recognition module 73 detects that the wiring harness is faulty, the first optical recognition module 72 or the second optical recognition module 73 activates the electrically controlled translation adjustment tension paddle 5 at the unloading end of the upper electrically controlled conveyor belt 2 to extend and reset, so that the faulty wiring harness will fall due to gravity to the separation box at the unloading end of the upper electrically controlled conveyor belt 2 or the separation box at the unloading port of the optical recognition module 7 on the lower electrically controlled conveyor belt 3.

[0048] In order to cooperate with the electric control positioning and ensure that the material guide box body 431 is unloaded and introduced into the lower lateral assembly seat 6, an infrared positioning module 8 is fixedly installed on the side wall of the material guide box body 431, and a side-mounted positioning lens 9 that cooperates with the infrared positioning module 8 is fixedly installed on the side wall of the lateral assembly seat 6.

[0049] In order to cooperate with installation and bottom unloading, an upper installation frame 10 for installing the upper electric-controlled conveyor belt 2 is fixedly installed on the horizontal main frame 1, and separation boxes 11 are installed at the unloading positions of the upper electric-controlled conveyor belt 2 and the lower electric-controlled conveyor belt 3 inside the horizontal main frame 1.

[0050] The separation box 11 of the lower electric-controlled conveyor belt 3 is respectively arranged at the optical recognition module 7 and the lower electric-controlled conveyor belt 3 .

[0051] The operator guides the wire harness into the electric-controlled feeding box 4, and then guides it to the upper electric-controlled conveyor belt 2 by using the electric-controlled feeding box 4, and then drives the wire harness to translate by the upper electric-controlled conveyor belt 2. During the translation process, the side assembly seat 6 is squeezed outward by the electric-controlled translation adjustment tension paddle 5, and then the side assembly seat 6 is used to squeeze the wire harness outward. When squeezing the side terminal of the wire harness, the force in the pulling process is detected by the pressure sensor 65. Once the pressure drops rapidly or is significantly lower than the pressure at the adjacent end, it means that the terminal of the wire harness is not firmly connected. Then the electric-controlled translation adjustment tension paddle 5 at the unloading end of the upper electric-controlled conveyor belt 2 is started to stretch and reset, so that the faulty wire harness will fall into the separation box 11 located at the unloading end of the upper electric-controlled conveyor belt 2 due to gravity.

[0052] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
