Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-4 As shown, an external pressure jig with the function of pre-pressing products includes an upper jig 1, a pre-pressing mechanism 21 is arranged at the bottom of the upper jig 1, the pre-pressing mechanism 21 includes a lower jig 211, a product fixing buckle 212 is arranged on the lower jig 211, a shoulder screw 213 is installed on the product fixing buckle 212, a spring 214 is sleeved on the shoulder screw 213, a product placement cavity 215 is opened on the lower jig 211, a product upper cover 4 is arranged inside the product placement cavity 215, and a product lower shell 5 is also arranged inside the product placement cavity 215.

[0023] Specifically, by placing the product lower shell 5 inside the product placement cavity 215, the product upper cover 4 is then connected to the product lower shell 5, and then the product fixing buckle 212 can be used to lock the product upper cover 4 through the shoulder screw 213 and the spring 214, and then the product lower shell 5 and the product upper cover 4 can be pre-pressed and fixed to facilitate subsequent processing.

[0024] like Figure 2As shown, a material picking mechanism 31 is also provided on the lower fixture 211, and the material picking mechanism 31 includes a screw 311, and a screw slider 312 is threadedly sleeved on the outer wall of the screw 311. The material picking mechanism 31 also includes a circular plate 313, and the circular plate 313 is fixedly connected to the screw slider 312. A rubber block 314 is fixedly installed on the top of the circular plate 313, and a sponge block 315 is fixedly installed on the top of the rubber block 314. The inner wall of the lower fixture 211 is rotatably connected to a worm 6 through a bearing, and a worm wheel 7 is meshedly connected to the outer wall of the worm 6. The worm wheel 7 is fixedly sleeved on the outer wall of the bottom end of the screw 311, and a motor 8 is fixedly installed on one side of the lower fixture 211 through a support plate, and the output end of the motor 8 is fixedly connected to one end of the worm 6.

[0025] Specifically, when it is necessary to take materials, the lock of the product fixing buckle 212 is canceled, and the motor 8 is started so that the output end of the motor 8 drives the fixedly connected worm 6 to rotate, thereby driving the worm wheel 7 meshing with the outer wall of the worm 6 to rotate, and then driving the screw 311 fixedly mounted on the inner wall of the worm wheel 7 to rotate, so that the screw slider 312 threadedly mounted on the outer wall of the screw 311 can be driven to move upward. Under the connection and limiting action of the circular plate 313, the rubber block 314 and the sponge block 315 move upward, so that the lower shell 5 of the product can be pushed out.
