[0019] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, 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.

[0021] See also Figure 1-Figure 3 As shown, the utility model is a wire blocking mechanism, comprising a fixed bracket 1, a positioning bracket 2 is fixedly installed on the top of the fixed bracket 1, and a card slot for clamping and positioning the terminal 3 is arranged on the top of the positioning bracket 2; a lifting and translation assembly, a positioning baffle 9 and a sensor 12 are also installed on the top of the fixed bracket 1, which are located on one side of the positioning bracket 2, and the lifting and translation assembly can drive the positioning baffle 9 to lift and translate in the direction of the positioning bracket 2, so that the positioning baffle 9 moves to the wire blocking position above the terminal 3, and the sensor 12 can obtain a signal when the front end of the wire hits the positioning baffle 9;
[0022] Among them, the wire blocking mechanism is installed on the ultrasonic welding equipment through a fixed bracket 1, and the sensor 12 is connected to the controller signal of the ultrasonic welding equipment. When the terminal 3 and the wire need to be welded and connected, the terminal 3 is first clamped and positioned by the positioning support block 2, and then the positioning baffle 9 is driven to move to one side of the welding position of the terminal 3 by the lifting and translation assembly, and then the end of the wire is pressed against the welding position of the terminal 3, and at the same time, the end of the wire abuts against one side of the positioning baffle 9, so that the wire is limited by the positioning baffle 9, so that the wire can be accurately aligned and connected with the terminal 3, thereby improving the welding accuracy between the terminal 3 and the wire, which is beneficial to improving the welding yield and the performance of the terminal 3 after welding; and when the end of the wire abuts against one side of the positioning baffle 9 so that the wire reaches the welding position, the sensor 12 can obtain the corresponding signal and transmit the signal to the controller, so that it is convenient for the ultrasonic welding equipment to obtain the positioning information of the terminal 3 and the wire, which is beneficial to the ultrasonic equipment to perform automatic welding.
[0023] Specifically, the lifting and translation assembly includes a lifting cylinder 4, which is fixedly installed on one side of the fixed bracket 1, a lifting bracket 5 is fixedly installed on the telescopic end of the top of the lifting cylinder 4, a translation cylinder 6 is installed on the top of the lifting bracket 5, and a positioning baffle 9 is connected and installed on one side of the top of the translation cylinder 6; the translation cylinder 6 includes a telescopic guide rod and a cylinder body connected in a telescopic manner, one end of the telescopic guide rod is fixedly connected to the side wall of the lifting bracket 5, a connecting seat 7 is fixedly installed on the top surface of the cylinder body, a connecting column 8 is slidably inserted at one end of the connecting seat 7, and a positioning baffle 9 is fixedly installed at one end of the connecting column 8;
[0024] After the terminal 3 is clamped and fixed on the top surface of the positioning bracket 2, the connecting seat 7, the connecting column 8 and the positioning baffle 9 are first driven to move to the left by the translation cylinder 6, so that the positioning baffle 9 is moved to the upper right side of the welding position of the terminal 3, and then the lifting bracket 5, the translation cylinder 6, the connecting seat 7, the connecting column 8 and the positioning baffle 9 are driven to move downward as a whole by the lifting cylinder 4, so that the lower end of the positioning baffle 9 is close to the top surface of the terminal 3 until the positioning baffle 9 is on the right side of the welding position of the top surface of the terminal 3, and then the end of the wire to be welded is tightly attached to the welding position of the top surface of the terminal 3, and the end of the wire abuts against the left side of the positioning baffle 9, so that the wire is positioned by the positioning baffle 9.
[0025] Specifically, a slide groove 11 is provided on the top surface of the connecting seat 7, a slider 10 is fixedly installed at one end of the connecting column 8, the lower end of the slider 10 is slidably engaged in the slide groove 11, a spring 13 is abutted against one end of the slider 10, a sensor 12 is fixedly installed inside the slide groove 11, and the detection end of the sensor 12 is located on one side of the slider 10, a linear bearing is fixedly installed at one end of the connecting seat 7, and the connecting column 8 is slidably inserted into the linear bearing;
[0026] Among them, the sensor 12 adopts a pressure sensor. When the end of the wire abuts against the left side of the positioning baffle 9, the wire pushes the positioning baffle 9 to the right. At this time, the positioning baffle 9 pushes the slider 10 to the right through the connecting column 8, so that the right side of the slider 10 abuts and squeezes the sensor 12. When the sensor 12 detects the pressure information, it means that the wire has been accurately positioned, so that the ultrasonic welding equipment can perform subsequent welding operations; and when the welding is completed, the lifting cylinder 4 and the translation cylinder 6 cooperate to drive the positioning baffle 9 to move and reset, and the positioning baffle 9 is separated from the wire and is no longer pushed by the wire. At this time, the slider 10 slides and resets along the slide groove 11 under the reset elastic force of the spring 13, so that the slider 10 is separated from the sensor 12 to facilitate the subsequent detection and use of the sensor 12.
