This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0026] Furthermore, in the description of this application, unless otherwise expressly specified and limited, the term "connected" should be interpreted broadly. For example, it can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0027] like Figure 1-2 As shown in the illustration, an embodiment of this application provides a device for shaping NTC resistor leads into an S-shape. The device includes a base 1, a clamping mechanism 2, a forming and clearance mechanism 3, and a positioning and pushing mechanism 4. The clamping mechanism 2 is disposed on the upper part of the base 1 and is used to clamp the NTC resistor leads 5. The forming and clearance mechanism 3 is disposed on the base 1 and is used to shape and clearance the clamped NTC resistor leads 5 into an S-shape. The positioning and pushing mechanism 4 is disposed on the base 1 and is used to position and move the NTC resistor leads 5 during shaping to ensure consistent dimensions.

[0028] Specifically, the base 1 serves as the main supporting structure of the entire equipment. The clamping mechanism 2, installed on the upper part of the base 1, firmly clamps the NTC resistor leads 5 to be processed during the forming process, preventing component displacement. The forming and clearance mechanism 3, also installed on the base 1, enables two operations: firstly, it performs a standard S-shaped bend on the clamped NTC resistor leads 5; secondly, it facilitates station clearance through its movement, allowing for easy component clamping and finished product removal. The positioning and pushing mechanism 4, also installed on the base 1, clamps and limits the NTC resistor leads 5 during the forming process, while simultaneously performing overall moving and feeding, effectively ensuring uniform forming dimensions for each product and supporting continuous mass production.

[0029] like Figure 1-2 As shown, in a preferred embodiment of this application, the clamping mechanism 2 includes a pressing plate mounting block 21, a component pressing plate 22, and a clamping slide cylinder 23. The pressing plate mounting block 21 is located on the upper part of the base 1; the component pressing plate 22 is located on the lower side of the pressing plate mounting block 21; the clamping slide cylinder 23 is located on the base 1, above the pressing plate mounting block 21, and connected to the pressing plate mounting block 21 to drive the pressing plate mounting block 21 and move the component pressing plate 22, thereby clamping and releasing the NTC resistor pin 5.

[0030] Specifically, the base 1 can be a cuboid structure, including four sides: a first side, a second side, a third side, and a fourth side. The pressure plate mounting block 21 is fixed to the first side of the base 1. The component pressure plate 22 is fixed to the underside of the pressure plate mounting block 21 and is a pressing component that directly contacts the workpiece. Preferably, the component pressure plate 22 can be a long strip structure. The pressing slide cylinder 23 can be an MXQ6-20A model slide cylinder, which is fixed to the base 1 and positioned above the pressure plate mounting block 21, with its output end connected to the pressure plate mounting block 21. During operation, the pressing slide cylinder 23 drives the pressure plate mounting block 21 to reciprocate along with the component pressure plate 22, thereby completing the pressing and releasing operation of the NTC resistor pin 5, ensuring that the component does not shift during the shaping process, and providing stable operating conditions for subsequent pin S-shaped shaping.

[0031] like Figure 1-2As shown, in a preferred embodiment of this application, the forming and avoiding mechanism 3 includes a sliding component 31, an angle swing component 32, and an avoiding component 33. The sliding component 31 is disposed on the base 1; the angle swing component 32 has a swing base point and can cooperate with the sliding component 31 to drive the NTC resistor pin 5 to swing around the swing base point to achieve S-shaped shaping of the NTC resistor pin 5; the avoiding component 33 can cooperate with the sliding component 31 to drive the NTC resistor pin 5 to move up and down to achieve avoiding of the NTC resistor pin 5; wherein, the angle swing component 32 and the avoiding component 33 act on the NTC resistor pin 5 simultaneously, and each resets and does not interfere with the other, so as to complete the S-shaped shaping and avoiding of the NTC resistor pin 5.

[0032] Specifically, the sliding assembly 31 is mounted on the base 1, providing sliding guide support for the entire molding structure. The angle swing assembly 32, around the swing base point, slides in cooperation with the sliding assembly 31, driving the NTC resistor pin 5 to swing around the base point at an angle, thereby completing the S-shaped bending and shaping operation of the NTC resistor pin 5. The avoidance assembly 33 also relies on the sliding assembly 31 for transmission cooperation, driving the corresponding component and the NTC resistor pin 5 to move up and down in a linear motion, thereby achieving station avoidance and facilitating component clamping and finished product removal. The angle swing assembly 32 and the avoidance assembly 33 are driven by independent cylinders. They act on the NTC resistor pin 5 simultaneously, with independent actions and non-interfering return paths. Under orderly cooperation, they efficiently complete the S-shaped shaping of the pin and station avoidance, ensuring continuous and stable operation of the equipment.

[0033] like Figure 1-2 As shown, in a preferred embodiment of this application, the sliding assembly 31 includes a slide rail 311, a slider, and a limiting block 312. The slide rail 311 is disposed on the base 1; the slider slides along the slide rail 311; the limiting block 312 is slidably disposed on the base 1 and is connected to the slider to move with the slider.

[0034] Specifically, the slide rail 311 is fixedly installed on the base 1, providing precise sliding guidance for the entire forming and avoidance mechanism; the slider is matched and assembled on the slide rail 311, and can slide smoothly back and forth along the slide rail 311; the limit block 312 is movably set on the surface of the base 1 and connected to the slider, and can move synchronously with the slider, which not only plays the role of limiting the stroke, but also serves as an intermediate connecting structure, respectively connecting the angle swing component 32 and the avoidance component 33, ensuring that the sliding stroke of each moving part is controllable and the transmission connection is stable.

[0035] like Figure 1-2As shown, in a preferred embodiment of this application, the angle swing assembly 32 includes a component shaping mold 321, a foot clamping block 322, a cylindrical pin 323, a floating connector 324, and a first cylinder 325. The component shaping mold 321 is located below the clamping mechanism 2 and is mounted on the slider; the foot clamping block 322 is located above the component shaping mold 321 and can move in opposite directions or towards each other; the cylindrical pin 323 is located below the component shaping mold 321 and serves as the swing base point of the component shaping mold 321; one end of the floating connector 324 is connected to the limiting block 312, and the other end is connected to the first cylinder to realize the S-formation of the NTC resistor pin.

[0036] Specifically, the component shaping mold 321 is arranged below the clamping mechanism 2 and fixedly installed on the slider, allowing it to slide synchronously with the slider. Two clamping blocks 322 are symmetrically assembled above the component shaping mold 321, forming a sliding fit that allows for relative swinging operation. A cylindrical pin 323 is located at the bottom of the component shaping mold 321, serving as a fixed base point for the swinging of the clamping blocks 322 and limiting their movement trajectory. One end of the floating connector 324 is connected to the limiting block 312, and the other end is connected to the first cylinder 325. Power is output from the first cylinder and transmitted sequentially through the floating connector 324, the limiting block 312, and the slider, causing the clamping blocks 322 to swing around the cylindrical pin 323 at an angle, thus cooperating with the mold to complete the S-shaped bending and shaping operation of the NTC resistor pin 5.

[0037] like Figure 1-2 As shown, in a preferred embodiment of this application, the avoidance component 33 includes a component shaping slider 331, a cylinder floating block 332, and a second cylinder 333. The component shaping slider 331 is located below the component shaping mold 321 and is disposed on the slider; one end of the cylinder floating block 332 is connected to a limiting block 312, and the other end is connected to the second cylinder 333, so as to realize the station avoidance after the NTC resistor pin 5 is formed.

[0038] Specifically, the component shaping slider 331 is arranged below the component shaping mold 321 and is also mounted on the slider. It can slide synchronously along the slide rail and cooperate with the shaping structure above. The cylinder floating block 332 serves as a transmission transition component, with one end connected to the limit block 312 and the other end connected to the second cylinder 333. After the operation is completed, the second cylinder 333 outputs power, which drives the component shaping slider 331 to move up and down linearly through the cylinder floating block 332, so that the entire mechanism is removed from the processing station, thus avoiding the NTC resistor pin 5 after forming. This structure and the angle swing component are independent of each other and their actions do not interfere with each other. It can not only leave sufficient space for clamping the components to be processed and picking up and placing the finished products, but also avoid collisions and interference between moving parts, ensuring the smooth operation of continuous automated equipment.

[0039] like Figure 1-2As shown, in a preferred embodiment of this application, the positioning and pushing mechanism 4 includes a first connecting block 41, a second connecting block 42, a positioning and pushing component 43, a motor module 44, and a positioning cylinder 45. The first connecting block 41 and the second connecting block 42 are connected to each other; the positioning and pushing component 43 is disposed on the base 1 and connected to the NTC resistor pin 5; the motor module 44 is disposed on the base 1 and connected to the first connecting block 41 and the positioning and pushing component 43 to push the moving parts of the positioning and pushing mechanism back and forth to realize the pushing action; the positioning cylinder 45 is connected to the first connecting block 41, the second connecting block 42, and the positioning and pushing component 43 to push the moving parts of the positioning and pushing mechanism left and right to realize the positioning operation.

[0040] Specifically, the second connecting block 42 is fixedly mounted above the first connecting block 41, and the two are rigidly connected. The entire positioning and pushing assembly 43 is arranged above the base 1, and during operation, it directly abuts against and clamps the NTC resistor pin 5 to achieve workpiece positioning. The moving parts of the positioning and pushing mechanism refer to the movable parts that are not fixed to the base. A linear motor module 44 is mounted on the base 1, and its output end is connected to the first connecting block 41 and the positioning and pushing assembly 43. During operation, it can drive all supporting components, including the first connecting block 41, the second connecting block 42, the positioning cylinder 45, and the positioning and pushing assembly 43, to move synchronously forward and backward in a linear fashion, completing the pushing action for workpiece conveying and station switching. The positioning cylinder 45 is mounted on the second connecting block 42 and connects the first connecting block 41 and the positioning and pushing assembly 43. It drives the positioning and pushing assembly to open and close left and right using its own power, clamping the NTC resistor pin 5 from both sides to achieve precise positioning. The two power structures have a clear division of labor, with the front and rear pushing and left and right positioning actions working together to effectively prevent the workpiece from shifting during the forming process, ensuring that the forming dimensions of each NTC resistor pin 5 are highly uniform, and meeting the requirements of automated continuous production.

[0041] like Figure 1-2 As shown, in a preferred embodiment of this application, the positioning and pushing assembly 43 includes a pushing main rod 431, a pushing guide rod 432, a connecting block 433, and a pushing connecting block 434.

The pushing guide rod 432 is inserted into the pin hole to cooperate with the pushing main rod 431. The connecting block 433 has a groove and opens and closes left and right under the action of the pushing guide rod 432. One end of the pushing connecting block 434 is connected to the connecting block 433, and the other end is connected to the positioning cylinder 45.

[0042] Specifically, the side wall of the pusher main rod 431 is machined with dedicated pin holes. One end of the pusher main rod is assembled onto the first connecting block 41 via a floating joint. The entire assembly is powered by the motor module 44, enabling overall displacement in the front-to-back direction. The pusher guide rod 432 is inserted into the pin holes of the pusher main rod 431, forming a sliding fit. It can move synchronously with the pusher main rod and transmit lateral force. The assembly block 433 has a groove inside for fitting and limiting the NTC resistor. Under the traction drive of the pusher guide rod 432, it completes a stable left-right opening and closing action, thereby clamping or releasing the workpiece. The pusher connecting block 434 serves as a power transfer component. One end is fixedly connected to the assembly block 433, and the other end is connected to the positioning cylinder 45. The positioning cylinder outputs power and transmits it to the assembly block 433 via the pusher connecting block 434. The entire assembly is driven by a motor module to complete front and rear feeding, while relying on a cylinder to achieve left and right clamping and positioning. The two actions work together to effectively fix the position of the NTC resistor, prevent deviation during the shaping process, ensure the consistency of product processing dimensions, and adapt to automated continuous production conditions.

The clamping mechanism 2, the forming and avoiding mechanism 3, and the positioning and pushing mechanism 4 are all orderly assembled on the side main plate 12, relying on this support structure to complete their respective actions. The mechanisms are compactly arranged and cooperate with each other to realize the automated shaping operation of the NTC resistor pins 5.

One end of the movable plate 112 is connected to the bottom cylinder 13, and the upper part of the movable plate 112 is connected to the lateral main plate 12, so that the lateral main plate 12 moves together with the movable plate 112.

[0046] Specifically, the equipment is also equipped with a bottom cylinder 13. The base plate 11 consists of a fixed plate 111 and a movable plate 112.
