Description

Technical Field

[0001] This utility model relates to the field of NTC resistor element processing technology, specifically to an NTC resistor element lead wire alignment assembly. Background Technology

[0002] NTC refers to the phenomenon and material of a thermistor whose resistance decreases exponentially with increasing temperature. This material is a semiconductor ceramic made by fully mixing, molding, and sintering two or more metal oxides such as manganese, copper, silicon, cobalt, iron, nickel, and zinc. It can be used to make thermistor elements with negative temperature coefficient (NTC).

[0003] However, NTC resistors require lead wire alignment during manufacturing. Existing lead wire alignment components require manual assistance, resulting in high labor intensity and low efficiency. Furthermore, existing lead wire alignment components are prone to damaging NTC resistors during the alignment process, thus reducing the yield rate. Utility Model Content

[0004] The purpose of this invention is to provide an NTC resistor lead straightening assembly to solve the problems of low working efficiency and low yield of existing lead straightening assemblies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an NTC resistor element lead straightening assembly, including a support frame, a straightening auxiliary mechanism provided on one side of the support frame, and a straightening mechanism connected to the surface of the support frame. The straightening mechanism works in conjunction with the straightening auxiliary mechanism to straighten the NTC resistor element leads. A clamping mechanism is connected to the surface of the support frame and above the straightening mechanism. The clamping mechanism is used to clamp the head of the NTC resistor element.

[0006] Preferably, the line-following auxiliary mechanism includes a vertical plate and a line-scraping baffle. The vertical plate is disposed on one side of the support frame, and the line-scraping baffle is fixed to the top of the vertical plate.

[0007] Preferably, the line-straightening mechanism includes a line-straightening cylinder, a connecting plate, a line-scraping cylinder, and a line-scraping rubber block. The line-straightening cylinder is fixedly connected to the surface of the support frame, and the output end of the line-straightening cylinder is equipped with a connecting plate.

[0008] Preferably, a scraping cylinder is installed at the bottom of the connecting plate via a fixing plate, and a scraping rubber block is fixed at the output end of the scraping cylinder. The scraping rubber block and the connecting plate slide against each other. The scraping rubber block, together with the scraping baffle, is used to scrape and straighten the lead wire.

[0009] Preferably, the clamping mechanism includes a bracket, a clamping cylinder, a slide, a pressure block, and a pressure spring, with the bracket fixedly connected to the surface of the support frame.

[0010] Preferably, a clamping cylinder is fixed to the surface of the bracket, a slide block is slidably connected to the surface of the bracket, and the surface of the slide block is fixedly connected to the output end of the clamping cylinder; a pressure block is slidably connected to the surface of the slide block, a pressure spring is fixedly connected to the end of the pressure block, and one end of the pressure spring is fixedly connected to the surface of the slide block.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This NTC resistor element lead straightening assembly, by setting a straightening mechanism, a clamping mechanism, and a straightening auxiliary mechanism, allows the head of the NTC resistor element to be clamped by the clamping mechanism during implementation. After clamping, the lead straightening mechanism, with the assistance of the straightening auxiliary mechanism, straightens the lead of the NTC resistor element. This utility model improves the automation level of NTC resistor element lead straightening, eliminating the need for manual operation during the lead straightening process, reducing labor intensity, and improving work efficiency. Moreover, when clamping the NTC resistor element, the elastic force of the spring drives the pressure block to slowly clamp, avoiding damage caused by excessive clamping, thereby increasing the yield rate.

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] The structure of the NTC resistor element lead-aligning assembly provided by this utility model is as follows: Figure 1 , Figure 2 as well as Figure 4 As shown, the system includes a support frame 1. A wire-straightening auxiliary mechanism 4 is provided on one side of the support frame 1. The wire-straightening auxiliary mechanism 4 includes a vertical plate 41 and a wire-scraping baffle 42. The vertical plate 41 is located on one side of the support frame 1. Both the vertical plate 41 and the support frame 1 are fixed to the frame, and the wire-scraping baffle 42 is fixed to the top of the vertical plate 41. A wire-straightening mechanism 2 is connected to the surface of the support frame 1. This wire-straightening mechanism 2, in conjunction with the wire-straightening auxiliary mechanism 4, is used for the wire-straightening operation of the NTC resistor element leads. The wire-straightening mechanism 2 includes a wire-straightening... The system includes a wire-straightening cylinder 21, a connecting plate 22, a wire-scraping cylinder 23, and a wire-scraping rubber block 24. The wire-straightening cylinder 21 is fixedly connected to the surface of the support frame 1, and the output end of the wire-straightening cylinder 21 is equipped with a connecting plate 22. The bottom end of the connecting plate 22 is equipped with a wire-scraping cylinder 23 through a fixing plate, and the output end of the wire-scraping cylinder 23 is fixed with a wire-scraping rubber block 24. The wire-scraping rubber block 24 and the connecting plate 22 slide against each other. The wire-scraping rubber block 24, together with the wire-scraping baffle 42, is used for the wire-scraping and straightening work of the lead wire.

[0020] During implementation, the wire-straightening cylinder 21 drives the scraper block 24 on the surface of the connecting plate 22 to push forward, so that the scraper block 24 is in contact with the lead wire of the NTC resistor element. After being in contact, it is pressed by the scraper baffle 42 on the surface of the vertical plate 41. Then, the scraper block 24 is moved down by the scraper cylinder 23 to complete the wire-straightening of the NTC resistor element lead wire.

[0021] Furthermore, such as Figure 3 as well as Figure 5As shown, a clamping mechanism 3 is connected to the surface of the support frame 1 and above the aligning mechanism 2. The clamping mechanism 3 is used to clamp the head of the NTC resistor element. The clamping mechanism 3 includes a bracket 31, a clamping cylinder 32, a slide block 33, a pressure block 34, and a pressure spring 35. The bracket 31 is fixedly connected to the surface of the support frame 1. The clamping cylinder 32 is fixedly connected to the surface of the bracket 31. The slide block 33 is slidably connected to the surface of the bracket 31, and the surface of the slide block 33 is fixedly connected to the output end of the clamping cylinder 32. The pressure block 34 is slidably connected to the surface of the slide block 33. The end of the pressure block 34 is fixedly connected to the pressure spring 35, and one end of the pressure spring 35 is fixedly connected to the surface of the slide block 33.

[0022] During implementation, the moving slide 33 is moved by the pressing cylinder 32 on the surface of the bracket 31. When it moves, the pressing block 34 presses the head of the NTC resistor element. When pressing, the pressing block 34 slowly presses the NTC resistor element by the elastic force of the compression spring 35.

[0023] Working principle: When in use, the head of the NTC resistor element is first pressed by the clamping mechanism 3. After pressing, the wire straightening mechanism 2, with the assistance of the wire straightening auxiliary mechanism 4, straightens the wires of the NTC resistor element, thereby completing the wire straightening work of the NTC resistor element.

[0024] In practice, the moving slide 33 is moved by the pressing cylinder 32 on the surface of the bracket 31. When it moves, the pressing block 34 presses the head of the NTC resistor element. When pressing, the spring force of the compression spring 35 makes the pressing block 34 press the NTC resistor element slowly, so as to avoid the NTC resistor element being damaged due to excessive pressing.

[0025] After the head of the NTC resistor element is pressed, the wire-scraping rubber block 24 on the surface of the connecting plate 22 is pushed forward by the wire-scraping cylinder 21, so that the wire-scraping rubber block 24 is attached to the lead of the NTC resistor element. After being attached, it is pressed by the support of the wire-scraping baffle 42 on the surface of the vertical plate 41. Then, the wire-scraping cylinder 23 drives the wire-scraping rubber block 24 to move down, thereby completing the wire-scraping work of the NTC resistor element.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
