Description

Technical Field

[0001] This utility model specifically relates to the field of lead bending and cutting technology, and more specifically to a thermistor lead bending and cutting mechanism. Background Technology

[0002] Thermistors, as semiconductor sensors whose resistance changes with temperature, are widely used in temperature measurement, control, and overheat protection in electronic devices. Their structure typically includes a resistor body and two leads. In actual assembly, to adapt to circuit board layout or equipment installation space requirements, the leads need to undergo precise bending and trimming to ensure consistent lead lengths and bending angles that meet assembly standards. Otherwise, it will directly affect the connection stability between the thermistor and other electronic components, leading to abnormal equipment performance. Bending and trimming the leads of thermistors largely rely on manual operation, which is not only slow and difficult to meet the needs of mass production, but also prone to poor product consistency due to human error, affecting the quality of subsequent assembly. In some processes, the straightening, bending, and trimming of leads need to be completed on multiple independent machines, each requiring a separate operator. This not only increases labor costs but also reduces production efficiency due to material transfer between processes. For example, some bending machines can only perform single-angle bending and can only process one workpiece at a time, while trimming requires a separate lead-cutting device, making the overall process cumbersome. A search revealed Chinese patent application CN202322946869.2, which describes a thermistor lead bending and cutting mechanism. The mechanism includes a base, a support platform, a bending section, and a cutting section. The base supports the bending and cutting mechanism, the support platform is mounted on the base for placing the thermistor, the bending section is slidably mounted vertically above the support platform for bending the thermistor leads, and the cutting section is slidably mounted horizontally on one side of the support platform for cutting the bent thermistor leads. The device in the aforementioned patent requires manual placement of the pins during the cutting process. This limits the cutting to a single pin and also necessitates manual loading, resulting in low efficiency during the cutting process. Utility Model Content

[0003] The purpose of this invention is to provide a thermistor lead bending and cutting mechanism. In this device, automatic feeding is achieved through a vibrating feeding screen and a rotating transmission frame. During the feeding process, automatic sorting is achieved. During the transmission of the thermistors, the clamping components allow the thermistors to pass through multiple placement frames in sequence. When the placement frames clamp the thermistors, the lead bending effect is also effectively achieved. Finally, the thermistors reach the two cutting structures at the end to cut off the excess leads, thereby solving the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: A thermistor lead bending and cutting mechanism includes a worktable; a vibrating feeding screen and a rotary transmission frame are installed on the worktable; wherein the rotary transmission frame has an opening slot for placing edge thermistors. A vibrating feeding frame is installed on the bottom side of the rotating transmission frame away from the vibrating feeding screen; an adjusting frame is fixedly installed on one side of the vibrating feeding frame; a pressure plate is detachably installed on the top of the adjusting frame; the end of the vibrating feeding frame away from the rotating transmission frame is fixedly installed with a U-shaped frame; the bottom of the U-shaped frame is fixedly installed with a second workbench; a rotating shaft is movably installed on the top of the U-shaped frame; a torsion spring is installed between one end of the rotating shaft and the U-shaped frame.

[0005] As a further technical solution of this utility model, a clamping frame is also installed on the rotating shaft; there are two clamping frames, and the center lines of the two clamping frames are on the same cross-section as the material rack of the rotating transmission frame.

[0006] As a further technical solution of this utility model, two symmetrical slide rails are fixedly installed on the second workbench; a first movable frame and a second movable frame are movably installed on the slide rails; the first movable frame and the second movable frame are respectively fixedly installed with the push rod of the third cylinder and the first cylinder.

[0007] As a further technical solution of this utility model, the first movable frame and the second movable frame are respectively equipped with a plurality of corresponding placement frames and a corresponding shearing structure; the shearing structure is located at the end of the plurality of placement frames.

[0008] As a further technical solution of this utility model, a linear module is also fixedly installed on the second workbench; a clamping assembly is movably installed on the top of the linear module; one side of the clamping assembly is provided with the same number of grippers as the placement frame and the shearing structure; the gripper includes a movable clamping plate and a fixed clamping plate, wherein; the movable clamping plate is fixedly installed to the push rod of the second cylinder through a connecting rod.

[0009] Compared with the prior art, the beneficial effects of this utility model are: In use, the thermistors are first transferred to the rotary conveyor frame via a vibrating feeding screen. The rotation of the rotary conveyor frame automatically transfers the thermistors to the vibrating feeding frame, which in turn automatically arranges and transfers the thermistors forward. This reduces manual intervention and improves feeding efficiency. In this invention, when the thermistor is transmitted to the end of the vibrating feeder away from the rotating conveyor, two clamping frames effectively block the thermistor to prevent it from falling. The linear module drives the clamping components to move laterally, so that multiple jaws can clamp and transmit the thermistor in sequence. In this invention, during transmission, multiple grippers sequentially place the thermistor onto a placement rack. These racks are respectively mounted on a first moving rack and a second moving rack. A third cylinder and a first cylinder move the racks along a slide rail, effectively achieving simultaneous bending of the thermistor leads while the racks grip them. When the thermistor leads are transmitted to the shearing structures at the ends of the first and second moving racks, the cooperation between the two shearing structures effectively trims any excess leads after bending.

When the thermistor is transferred to the end of the vibrating feeder 10 away from the rotating conveyor 3, the two clamping frames 19 effectively block the thermistor to prevent it from falling. The linear module 13 drives the clamping component 5 to move laterally, so that multiple jaws 15 clamp and transfer the thermistor in sequence. During transmission, the thermistors are placed on the placement racks 7 sequentially by multiple grippers 15.
