[0047] It should be noted that, without conflict, the embodiments and features in the embodiments of the present application may be combined with each other. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0049] Please refer to Figure 1-6 , the embodiment provided by the present utility model:

[0050] As Figure 1 shown, an automobile wire harness sheath terminal plugging guiding mechanism includes a support frame 1 for installing a sheath loading component 8 and a plugging component 9, and driving components 3 installed on the side wall and inside of the support frame 1 respectively provide moving power for the sheath loading component 8 and the plugging component 9;

[0051] Specifically, as Figure 2As shown in the figure, there are two sets of driving components 3. The installation directions of the two sets of driving components 3 are opposite. The movable end of the driving component 3 installed on the side wall of the support frame 1 is fixedly installed with the plug-in component 9, and the movable end of the driving component 3 installed inside the support frame 1 is fixedly installed with the sleeve loading component 8. The top surface of the support frame 1 is installed with a first linear guide rail 2. The first slide table 5 and the second slide table 7 are respectively slidably connected to the first linear guide rail 2. The top surface of the first slide table 5 is fixedly installed with the plug-in component 9, and the top surface of the second slide table 7 is fixedly installed with the sleeve loading component 8

[0052] The support frame 1 includes a top plate 11 and two side plates 12. The two sides of the bottom surface of the top plate 11 are respectively fixedly installed with the side plates 12 by screws. The driving component 3 installed on the side wall of the support frame 1 includes a fixed seat 31, a servo motor 32, a coupling 33, a fixing plate 34, a ball screw 35, a nut 36 and a support plate 37. The side wall of the side plate 12 is fixedly installed with the fixed seat 31 by screws. The side wall of the fixed seat 31 is fixedly installed with the servo motor 32 by screws. The output shaft of the servo motor 32 is fixedly installed with one end of the ball screw 35 through the coupling 33. The side wall of one end of the ball screw 35 is fixedly installed with the inner ring of the bearing inside the fixing plate 34. The fixing plate 34 is installed on the side wall of the side plate 12 by screws. The other end of the ball screw 35 is fixedly installed with the inner ring of the bearing installed inside the support plate 37. The support plate 37 is fixedly installed on the side wall of the side plate 12 by screws. The nut 36 is threadedly connected to the side wall of the ball screw 35, and the nut 36 is located on the side wall of the ball screw 35 between the fixing plate 34 and the support plate 37. The nut 36 of the driving component 3 installed on the side wall of the support frame 1 is fixedly installed with the bottom of the first connecting plate 4. The top of the first connecting plate 4 is fixedly installed with one side of the top surface of the first slide table 5;

[0053] The servo motor 32 drives the ball screw 35 to rotate forward and backward between the fixing plate 34 and the support plate 37, so that the nut 36 can change its position on the side wall of the ball screw 35 according to the rotation direction of the ball screw 35, thereby driving the first connecting plate 4 and the first slide table 5 to move, so that the plug-in component 9 installed on the first slide table 5 can be guided to move along the path of the first linear guide rail 2.

[0054] Similarly, as Figure 3As shown in the figure, the fixed seat 31, the fixed plate 34 and the support plate 37 in the driving component 3 installed inside the support frame 1 are fixedly installed on the bottom surface of the top plate 11 according to the corresponding distances installed on the side plate 12. The nut 36 of the driving component 3 installed inside the support frame 1 is fixedly installed with the bottom of the second connecting plate 6. The top of the second connecting plate 6 is fixedly installed with the side wall of the second sliding table 7. According to the movement principle of the driving component 3 installed on the side wall of the support frame 1 as described above, the second connecting plate 6 can drive the second sliding table 7 to slide on the first linear guide rail 2, so as to adjust the position of the sheath loading component 8 on the first linear guide rail 2.

[0055] It should be noted that the sheath loading component 8 and the plugging component 9 move towards or away from each other along the direction of the first linear guide rail 2 on the first linear guide rail 2 under the drive of the driving component 3, so as to enable the sheath fixed on the sheath loading component 8 to be subjected to terminal plugging treatment through the plugging component 9.

[0056] As Figure 4 shown, the top of the sheath loading component 8 clamps the sheath tightly through parallel jaws. Specifically, the sheath loading component 8 includes a pressing block 81, a second linear guide rail 82, a first carrier 83, a pressure sensor 84 and parallel jaws. The top surface of the second sliding table 7 is fixedly installed with the second linear guide rail 82. The first carrier 83 is installed on the second linear guide rail 82 and is slidably connected thereto. One side of the first carrier 83 is fixedly installed with a pressing block 81 through screws. A connector 88 is fixedly installed inside the pressing block 81. The end of the connector 88 is fixedly installed with the pressure sensor 84. The pressure sensor 84 is fixedly installed on the side wall of the stepped part of the second sliding table 7. The parallel jaws include a double-acting cylinder 85, a left clamping seat 86 and a right clamping seat 87. The double-acting cylinder 85 is installed on the top surface of the first carrier 83. The two movable ends of the double-acting cylinder 85 are respectively fixedly installed with the left clamping seat 86 and the right clamping seat 87. The opposite sides of the left clamping seat 86 and the right clamping seat 87 are provided with profiled cavities for placing the sheath.

[0057] Through the opening and closing movements of the two movable ends of the double-acting cylinder 85 to drive the left clamping seat 86 and the right clamping seat 87, the sheath placed in its profiled cavity is clamped and fixed to ensure that the position will not change during the plugging of the terminal and the accuracy of the plugging position is guaranteed. At the same time, through the cooperation of the second linear guide rail 82 with the connector 88 and the pressure sensor 84, when plugging the terminal, the parallel jaws are stressed, causing the first carrier 83 to move in position on the second linear guide rail 82. Due to the fixation of the connector 88 and the pressure sensor 84, the magnitude of the acting force can be obtained through the pressure sensor 84. At the same time, after the terminal is installed, the sheath can be driven by the driving component 3 to drive the second sliding table 7 away from the first sliding table 5, resulting in pulling the pressure sensor 84 to drive the sheath to move a set distance for the pull-out force test.

[0058] As shown Figure 5 in the figure, the top side wall of the plugging component 9 installs the guiding pin 910 through the plug barrel 99. Specifically, the plugging component 9 includes a second carrier 91, a vertical plate 92, a limit seat 93, a set screw 94, a spring 95, a slider 96, a third sliding table 97, a third linear guide rail 98, a plug barrel 99 and a guiding pin 910. The second carrier 91 is installed on the top surface of the first sliding table 5, the vertical plate 92 is installed on the top surface of the second carrier 91, the limit seat 93 at the tail of the vertical plate 92 is installed on the top surface of the second carrier 91, the third linear guide rail 98 is installed on the top surface of the vertical plate 92, the third sliding table 97 is on the top surface of the third linear guide rail 98, the top surface of the third sliding table 97 is fixedly installed with the bottom surface of the slider 96. The set screw 94 is slidably installed inside the top of the limit seat 93, the threaded end of the set screw 94 is threadedly connected to the side wall of the slider 96, the spring 95 is sleeved on the side wall of the set screw 94 between the slider 96 and the limit seat 93, the side wall of the slider 96 is fixedly installed with the plug barrel 99, the guiding pin 910 is plugged and installed inside the plug barrel 99. By driving the component 3 to drive the slider 96 to approach the fixed sheath, the two guiding pins 910 are inserted into the sheath until they contact the two wire harness terminals. Continuing to insert, the guiding pin 910 is inserted into the wire harness terminal until the tip of the guiding pin 910 abuts against the terminal, and there is no relative movement between the guiding pin 910 and the terminal. At this time, the slider 96 fixing the guiding pin 910 and the third linear guide rail 98 generate relative displacement through the spring 95. On the top surface of the second carrier 91 and on one side of the vertical plate 92, a U-shaped photoelectric sensor 911 is fixedly installed, and a baffle 912 is fixedly installed on the side wall of the slider 96. The moving path of the baffle 912 is located in the U-shaped groove of the U-shaped photoelectric sensor 911.

[0059] Thus, the slider 96 drives the baffle 912 to move into the U-shaped groove of the U-shaped photoelectric sensor 911, so that it can be known whether the guiding pin 910 is plugged into the terminal by the triggering of the U-shaped photoelectric sensor 911.

[0060] As a preferred technical solution of the present application, as Figure 2 shown in the figure, one end of the drag chain 10 is fixedly installed on the top surface of the support frame 1 and on one side of the first linear guide rail 2 and the plugging component 9, and the other end of the drag chain 10 is fixedly installed on the side wall of the first sliding table 5 through screws. By adding the drag chain 10, it is ensured that the slider 96 is not prone to shaking when moving on the first linear guide rail 2.

[0061] The above are only the preferred embodiments of the present application and are not used to limit the present application. For those skilled in the art, the present application can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
