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.

[0030] Figure 1 , Figure 2 , Figure 3 and Figure 4A rotating continuous multi-environment testing mechanism for wire harness detection is shown, comprising a main frame 1 and a lower electrically controlled conveyor belt 2 installed on the main frame 1, an upper assembly frame 3 is fixedly installed on the upper end of the main frame 1 through a lateral frame, an upper electrically controlled conveyor belt 4 is movably installed inside the upper assembly frame 3, a plurality of elastic connection terminals 5 for externally connecting different signal receiving ends and output ends are fixedly installed on the outer walls of both sides of the upper assembly frame 3, lateral assembly terminals 6 matching the elastic connection terminals 5 are fixedly installed on both sides of the outer surface of the upper electrically controlled conveyor belt 4, an electrically controlled locking frame 7 is installed on the lateral assembly terminals 6, a plurality of bottom screening baskets 8 are installed on the main frame 1 at one side of the output port of the lower electrically controlled conveyor belt 2, and an electrically controlled separation mechanism 9 is installed on the inner side of the lateral assembly terminal 6.

[0031] In order to facilitate the lateral transition, the inner walls on both sides of the upper assembly frame 3 are provided with outwardly recessed lateral transition grooves 10 at positions corresponding to the elastic connecting terminals 5 .

[0032] In order to facilitate assembly, a position-adjustable wire harness assembly seat 11 is installed on the outer surface of the lower electrically-controlled conveyor belt 2 .

[0033] Working principle: People put the two sides of the wire harness on the two ends of the position-adjustable wire harness assembly seat 11, and then translate it with the lower electric-controlled conveyor belt 2. When it translates to the bottom of the upper electric-controlled conveyor belt 4, the electrically controlled locking frame 7 squeezes the terminals at both ends of the wire harness into the lateral assembly terminals 6, and then translates through the upper electric-controlled conveyor belt 4, and then connects with the elastic connection terminal 5 during the translation, so that the wire harness will be connected to the external different signal receiving ends and output ends, so as to detect the stability and rate of its signal transmission, judge its adaptability, and then separate it at different positions according to whether the set requirements are met, so as to perform screening operations according to the bottom screening basket 8 at different positions.

[0034] In order to cooperate with lateral adjustment, the position-adjustable wire harness assembly seat 11 includes a transverse adjustment seat 111 fixed on the outer surface of the lower electric-controlled conveyor belt 2, an externally threaded adjustment shaft 112 movably assembled inside the transverse adjustment seat 111, an internally threaded translation block 113 threadedly sleeved on the externally threaded adjustment shaft 112, and an external limit frame 114 fixed on the outer side of the internally threaded translation block 113.

[0035] An external adjustment block is axially sleeved on the middle part of the external thread adjustment shaft 112, and the external adjustment block can be rotated by a wrench to control the rotation of the external thread adjustment shaft 112, thereby controlling the outward translation of the internal thread translation block 113, thereby controlling the outward translation of the external limit frame 114, and then the terminals at both ends of the wiring harness are sleeved on the external limit frame 114, and then the wiring harness is controlled to translate and extend to both sides through the external limit frame 114.

[0036] In order to facilitate lateral data connection and transmission, the outer side of the lateral assembly terminal 6 has a plurality of offset terminals 12 protruding toward the inside of the lateral transition groove 10 .

[0037] In order to cooperate with the lateral connection and the inner contact, the elastic connection terminal 5 includes an external assembly frame 51 fixed on the outer walls of both sides of the upper assembly frame 3 and a plurality of elastic metal strips 52 fixed on the inner assembly surface of the external assembly frame 51 .

[0038] People connect the signal transmission line of the external device to the external assembly frame 51, and then the multiple staggered terminals 12 on the lateral assembly terminals 6 on the upper electric control conveyor belt 4 slide along the side transition groove 10 and contact the elastic metal strip 52 respectively, so as to transmit data and ensure that the wiring harness can still maintain its normal signal transmission during the movement, so as to judge its transmission performance.

[0039] In order to cooperate with the lateral assembly locking, the electric control locking frame 7 includes an electric control support rod 71 fixed on the side wall of the lateral assembly terminal 6 and a locking frame 72 axially fixed on the protruding end of the electric control support rod 71 .

[0040] When the position-adjustable wire harness assembly seat 11 on the lower electric control conveyor belt 2 is pre-installed with the wire harness, and then the lower electric control conveyor belt 2 drives it to move horizontally to the bottom of the upper electric control conveyor belt 4, the upper electric control conveyor belt 4 drives the lateral assembly terminals 6 to move to the outside of the terminals on both sides of the wire harness, and the electrically controlled locking frame 7 moves to the inner side of the upper ends of the terminals on both sides of the wire harness, and then the electrically controlled support rod 71 controls the locking block 72 to contract, thereby squeezing the terminals on both sides of the wire harness into the inside of the lateral assembly terminals 6.

[0041] In order to facilitate front-end loading and unloading and top unloading, a front loading and unloading port 13 for loading and unloading the bottom screening basket 8 is opened on the side wall of the main frame 1, and an upper unloading port 14 connected to the upper end opening of the bottom screening basket 8 is opened on the upper surface of the main frame 1.

[0042] When people need to load and unload, they operate the bottom screening basket 8 from the front loading and unloading port 13, and the wire harness falls into the bottom screening basket 8 through the upper unloading port 14.

[0043] In order to cooperate with the lateral assembly, the side walls of the lateral assembly terminal 6 are provided with arc-shaped assembly cylinders 15 protruding outwards.

[0044] The electrically controlled separation mechanism 9 is assembled through the arc-shaped assembly tube 15, so as to facilitate control.

[0045] In order to cooperate with electromagnetic control, the electrically controlled separation mechanism 9 includes a telescopic shaft 91 inserted into the inside of the arc-shaped assembly tube 15, an internal control block 92 fixed to the inner end of the telescopic shaft 91, an annular electromagnet 93 fixed on the inner wall of the arc-shaped assembly tube 15, an iron spring 94 installed between the internal control block 92 and the annular electromagnet 93, and an external extrusion frame 95 fixed to the protruding end of the telescopic shaft 91.

[0046] For the convenience of control, an infrared receiving switch is installed on the outer surface of the arc-shaped assembly cylinder 15. Then, when there is a problem with the data transmission or it is qualified, an infrared transmitting switch will be installed above the different bottom screening baskets 8. By starting the infrared transmitting switch at this position to transmit infrared rays to the infrared receiving switch, the annular electromagnet 93 is optically positioned and controlled.

[0047] When it is necessary to separate the terminals on both sides of the wiring harness, it is only necessary to start the annular electromagnet 93, which controls the iron spring 94 to contract, and then the iron spring 94 controls the internal control block 92 to drive the telescopic shaft 91 to telescope and adjust, and then the outer terminals of the wiring harness are squeezed outward through the external extrusion frame 95 to separate them from the inside of the lateral assembly terminal 6, and then the wiring harness will fall downward to the upper discharge port 14 at this position, and then fall into the bottom screening basket 8.

[0048] 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.
