In the above embodiment, as shown in fig. 2, the wire harness clamping mechanism 2 includes a pair of claw arms 21 that can be folded or unfolded by the respective driving members 22, the lower ends of the two claw arms 21 are respectively and correspondingly provided with the left clamping jaw 23 and the right clamping jaw 24, and when the two claw arms 21 are folded, the wire harness is just clamped between the left clamping jaw 23 and the right clamping jaw 24.
Furthermore, a sliding rail 11 is arranged on the middle plate 1, two displacement blocks 12 are slidably mounted on the sliding rail 11, and the two displacement blocks 12 are respectively and fixedly connected with a claw arm 21.
It should be noted that, in this embodiment, the driving member is a standard member of a clamping jaw cylinder. Because the back surfaces of the two claw arms are respectively fixed on a displacement block, the two claw arms slide along the length direction of the sliding track in opposite directions under the action of the driving piece at the side part of the claw arms, so that the two claw arms are mutually folded or unfolded.
Specifically, the terminal clamping mechanism 3 is a pneumatic clamping jaw type structure, and in order to further accurately position the relative position between the clamped terminal and the rubber shell on the terminal clamping mechanism, the terminal clamping mechanism can be selectively installed on the middle plate in a sliding manner through a Z-axis robot, so that the direction of the terminal clamping mechanism in height can be finely adjusted.
In the above embodiment, as shown in fig. 3, the pressure sensor module 5 includes a pressure sensor 53 disposed inside the claw arm 21, a deformation body 51 is fixed on the claw arm 21 through a pin 52, one end of the deformation body 51 is in contact with the left/right clamping jaws, and the other end is in contact with the pressure sensor 53.
In the process of testing the drawing force, the force along the drawing direction of the wire harness directly acts on the left clamping jaw and the right clamping jaw, and the lower end of the deformation body is tightly abutted to the left clamping jaw/the right clamping jaw, so that the deformation body can also receive the acting force, and the acting force sensed by the deformation body is transmitted to the pressure sensor in contact with the other end of the deformation body by taking the fixing position of the pin as a fulcrum.
Further, at least one of the claw arms 21 is provided with an auxiliary guide 25. The wire harness guiding and correcting device has the advantages that the wire harness is guided and corrected, and the wire harness is smoothly clamped between the left clamping jaw and the right clamping jaw.

The groove-type photoelectric switches are two in total, wherein the upper limit is one, the lower limit is one, and the initial position of an upper induction sheet of the pulling plate is positioned below the lower limit. The groove type photoelectric switch is formed by combining an infrared transmitting tube and an infrared receiving tube, and has the functions that when an induction sheet on the first pulling plate moves to a position between grooves on the groove type photoelectric switch, the groove type photoelectric switch generates a level trigger signal, the level trigger signal is opposite to a signal between the original states of the groove type photoelectric switch, and when the Z-axis displacement assembly receives the signal, the current position or the running state is judged, so that a corresponding control command is made.
In view of realizing full automation and reducing the movement error rate, the Z-axis displacement assembly 42 and the X-axis displacement assembly 45 in the embodiment both adopt a lead screw and nut mechanism driven by a servo motor. Other displacement mechanisms such as single axis robots are of course possible.
