The dropping area 7 can be a channel, and the female conductive terminal slides through the channel to a female conductive terminal collecting container.

[0035] The rack 1, the sleeve feeding mechanism 2, the terminal body feeding mechanism 3, the sleeve clamping mechanism 8, the terminal body clamping mechanism 6, the assembly table 4, the blanking area 7, the synchronous transmission mechanism 5 and the like are arranged in the embodiment, so that the automatic assembly equipment can realize the automatic assembly of the female conductive terminal. Specifically, the sleeve 10 is conveyed to the sleeve waiting area 22 by the sleeve feeding mechanism 2, the terminal body 9 is conveyed to the terminal body waiting area 62 by the terminal body feeding mechanism 3, the terminal body clamping mechanism 6 moves between the terminal body waiting area 62 and the assembly table 4, so as to realize the clamping and transfer of the terminal body 9 from the terminal body waiting area 62 to the assembly table 4, the terminal body 9 is positioned on the assembly table 4 in the vertical direction by the terminal body clamping mechanism 6 to wait for the sleeve 10 to be sleeved, the sleeve clamping mechanism 8 moves between the sleeve waiting area 22 and the assembly table 4, so as to realize the clamping and transfer of the sleeve 10 from the sleeve waiting area 22 to the assembly table 4 and the sleeving on the terminal body 9, and the terminal body clamping mechanism 6 and the sleeve clamping mechanism 8 are connected by the synchronous transmission mechanism 5, so that the sleeve clamping mechanism 8 and the terminal body clamping mechanism 6 can move synchronously, and the terminal body 9 and the sleeve 10 are assembled on the assembly table 4; the female conductive terminal after assembly is moved to the terminal body waiting area 62 by the terminal body clamping mechanism 6, so as to drive it to fall out of the blanking area 7, and the automatic assembly equipment can realize the automatic assembly of the female conductive terminal, so as to effectively improve the production efficiency of the female conductive terminal and reduce the production cost.

[0036] In combination Figure 4 and Figure 5As shown, the synchronous transmission mechanism 5 comprises a linear drive mechanism 50 fixed on the rack 1, a deflector 52 arranged away from the linear drive mechanism 50, a transmission belt 51 and a tension spring 53, the driving end of the linear drive mechanism 50 is connected with the sleeve clamping mechanism 8, one end of the transmission belt 51 is connected with the sleeve clamping mechanism 8, the other end of the transmission belt 51 extends to one side of the deflector 52, passes around the deflector 52 and is connected with the terminal body clamping mechanism 6, one end of the tension spring 53 is connected with the terminal body clamping mechanism 6 and the other end is connected with the rack 1, when the linear drive mechanism 50 pulls the sleeve clamping mechanism 8 to move, the terminal body clamping mechanism 6 is driven to move by the transmission belt 51 and the tension spring 53 is stretched to store energy, in this process, the sleeve clamping mechanism 8 moves to the sleeve taking area 22, and the terminal body clamping mechanism 6 moves to the terminal body taking area 62; when the linear drive mechanism 50 drives the sleeve clamping mechanism 8 to move reversely, the tension spring 53 contracts and drives the transmission belt 51 and the terminal body clamping mechanism 6 to move, in this process, the sleeve clamping mechanism 8 moves to the assembly table 4, and the terminal body clamping mechanism 6 moves to the assembly table 4; in this embodiment, the linear drive mechanism 50, the transmission belt 51 and the tension spring 53 can realize high-efficiency linkage between the terminal body clamping mechanism 6 and the sleeve clamping mechanism 8; the linear drive mechanism 50 is preferably a cylinder.

[0037] In the specific working process, when the linear drive mechanism 50 pulls the sleeve clamping mechanism 8 to move to the sleeve taking area 22, the terminal body clamping mechanism 6 is driven to move to the terminal body taking area 62 by the transmission belt 51, and in this movement, the tension spring 53 is stretched to store energy and provide power support for the subsequent action; when the linear drive mechanism 50 acts reversely, the contraction of the tension spring 53 drives the transmission belt 51 and the terminal body clamping mechanism 6 to move, at this time, the sleeve clamping mechanism 8 and the terminal body clamping mechanism 6 move to the assembly table 4, and this reverse movement ensures that the two are highly consistent in the feeding process, this design not only simplifies the structure, but also improves the stability of the working performance and ensures the consistency and reliability in the repeated operation process. In addition, the existence of the deflector 52 changes the direction of the transmission belt 51, so that the overall mechanism is more flexible to better adapt to the action requirements. Overall, through the reasonable configuration of the linear drive mechanism 50, the transmission belt 51 and the tension spring 53, the synchronous transmission mechanism 8 successfully realizes the synchronous feeding and feeding functions, significantly simplifies the mechanical structure, improves the stability and repeatability of the working performance, and provides strong support for improving the production efficiency.

[0038] As Figures 8 to 10As shown, the sleeve clamping mechanism 8 is a high-efficiency mechanical device aiming to realize accurate taking and placing of the sleeve 10. Specifically, the sleeve clamping mechanism 8 comprises a sliding seat 81 capable of moving laterally on the rack 1, an outer sleeve 83 capable of moving up and down and arranged on the sliding seat 81, a first spring 85 providing upward elastic force for the outer sleeve 83, an inner sleeve rod 84 arranged in the outer sleeve 83 and capable of moving up and down relative to the outer sleeve 83, and a second spring 86 providing upward elastic force for the inner sleeve rod 84. The sliding seat 81 is connected with the linear driving mechanism 50. The lower end of the inner sleeve rod 84 is provided with a punch 840 which is adapted to form interference fit with the sleeve 10 so as to ensure that the sleeve 10 can be fixed firmly on the punch 840 during the taking and placing operation. The lower end of the outer sleeve 83 is adapted to form a resisting portion 820 resisting the sleeve 10. The rack 1 is provided with a first pressing mechanism 20 above the sleeve taking area 22. The first pressing mechanism 20 is adapted to exert downward pressure on the inner sleeve rod 84 so that the punch 840 at the lower end of the inner sleeve rod 84 extends out of the lower end of the outer sleeve 83 and is inserted into the sleeve 10. In order to complete the disengagement operation of the sleeve 10 from the punch 840, the rack 1 is provided with a second pressing mechanism 30 above the assembling table 4. The second pressing mechanism 30 is adapted to exert downward pressure on the outer sleeve 83 and push the sleeve 10 away from the punch 840 through the resisting portion 820 so that the sleeve 10 is sleeved on the terminal body 9 on the assembling table 4 below (the terminal body 9 is positioned on the assembling table 4 by the terminal body clamping mechanism 8). The first pressing mechanism 20 and the second pressing mechanism 30 preferably adopt air cylinders. The power output end of the first pressing mechanism 20 has a smaller diameter, and the power output end of the second pressing mechanism 30 has a larger diameter so that the power output end of the first pressing mechanism 20 can extend into the outer sleeve 83 to exert downward pressure on the upper end of the inner sleeve rod 84, and the power output end of the second pressing mechanism 30 can abut against the upper end of the outer sleeve 83 to exert downward pressure on the outer sleeve 83.

[0039] For example, in order to realize the sliding operation of the sliding seat 81, a slide rail can be fixed laterally on the rack 1, and a sliding block capable of slidingly cooperating with the slide rail is fixed on the sliding seat 81. The cooperation between the sliding block and the slide rail realizes the sliding installation of the sliding seat 81 on the rack 1.

[0040] Specifically, when the sleeve is gripped, the inner sleeve rod 84 is moved downward by the first pressing mechanism 20 when the sleeve gripping mechanism 8 moves above the sleeve taking area 22, and then the punch 840 at the lower end of the inner sleeve rod 84 extends into a sleeve 10 in the sleeve taking area 22, so that the sleeve 10 can be firmly sleeved and fixed on the punch 840, realizing the gripping of the sleeve 10 to prevent loosening and falling off during movement; after the sleeve 10 is gripped, the first pressing mechanism 20 removes the downward pressure on the inner sleeve rod 84, and the inner sleeve rod 84 can move upward under the elastic force of the second spring 86, at which time the upper end of the sleeve 10 on the punch 840 is resisted on the resisting portion 820 of the outer sleeve 83 (the sleeving force of the sleeve 10 on the punch 840 is greater than the elastic force of the second spring 86, so as to prevent the sleeve 10 from easily falling off the inner sleeve rod 84); when the sleeve gripping mechanism 8 moves above the assembly table 4, the sleeve 10 on the punch 840 is above the terminal body 9 on the assembly table 4, and then the second pressing mechanism 30 applies downward pressure to the outer sleeve 83, forcing the resisting portion 820 on the outer sleeve 83 to push the sleeve 10 downward, so that it smoothly separates from the punch 840 and is accurately sleeved on the terminal body 9, the whole process is rationally designed, ensuring effective gripping and installation of the sleeve 10, and embodying good structural stability.

[0041] As shown in Figure 5 and Figure 7 , the terminal body gripping mechanism 6 includes a clamping jaw mounting frame 610 that can move laterally on the rack 1 and opening and closing clamping jaws 61 mounted on the clamping jaw mounting frame 610, the clamping jaw mounting frame 610 is connected with the transmission belt 51 and the tension spring 53, the opening and closing clamping jaws 61 clasp the terminal body 9 when closed, ensuring its stability during the entire operation process, and when the terminal body 9 needs to be released, the opening and closing clamping jaws 61 are opened, thereby releasing the clamping of the terminal body 9; when the terminal body gripping mechanism 6 is in the terminal body taking area 62, the opening and closing clamping jaws 61 are first kept in an open state, so that the terminal body 9 can smoothly fall into the terminal body taking area 62, and then the terminal body 9 falls into the terminal body taking area 62 and is in the opening and closing clamping jaws 61, the terminal body is clamped by closing the opening and closing clamping jaws 61, and then driven by the synchronous transmission mechanism 5 to move to the assembly table 4 to realize the conveying of the terminal body to the assembly table 4.

[0042] For example, in order to enhance the stability of the clamping jaw mounting frame 610 installed on the rack 1, a sliding rail can be fixed on the rack 1, a slidable sliding table is arranged on the sliding rail, the clamping jaw mounting frame 610 is fixedly connected with the sliding table, and effective slidable installation of the clamping jaw mounting frame 610 on the rack 1 is realized.
