Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of split pin devices, for the two pins of single-end glass-sealed thermistor are separated by predetermined distance. BACKGROUND

[0002] Single-end glass-sealed thermistor is a common electronic component, which is widely used in electrical automation equipment. Single-end glass-sealed thermistor is welded with other electronic components. Before welding, the two parallel pins of single-end glass-sealed thermistor need to be separated by predetermined distance.

[0003] Chinese patent application 202422609142X discloses a resistance split pin device, which includes a split pin needle inserted between the two pin wires of the resistance to separate the pin wires by a predetermined distance. Since the split pin needle is inserted close to the head of the thermistor, and the head of the thermistor is packaged with glass sintering. The closer the split pin needle is inserted between the two pins, the more likely it is to cause the packaging glass of the head to break; the farther away from the head, the split pin needle cannot deform the pins to separate the pins by a predetermined distance. SUMMARY

[0004] The utility model aims to provide a kind of split pin device for single-end glass-sealed thermistor, which can separate the two pins by a predetermined distance without damaging the packaging glass of the head of the thermistor.

[0005] To achieve the above-mentioned purpose, the split pin device of the utility model includes a lower support portion, a clamping portion and a wire splitter. The lower support portion is used to support the pins of the single-end glass-sealed thermistor. The clamping portion is used to clamp the single-end glass-sealed thermistor and convey it to the lower support portion. The wire splitter can extend between the two pins in a direction perpendicular to the length of the pins to separate the two pins by a predetermined distance. The split pin device also includes a limiting sheath, which is used to limit the separation distance of the part of the pin close to the head. The limiting sheath is arranged side by side with the wire splitter. The single-end glass-sealed thermistor includes a head and two parallel pins.

[0006] The limiting sheath is provided in the split pin device of the utility model, which can prevent the part of the pin close to the head of the single-end glass-sealed thermistor from being separated by the wire splitter. The part close to the head remains almost unchanged, thereby avoiding the packaging glass of the head from being broken.

[0007] In one embodiment, the limiting sheath has a limiting slot for accommodating the pin. The limiting slot restricts the two pins therein, and the pin portion in the limiting slot cannot move excessively.

[0008] In one embodiment, the pin separating device comprises a first driving part and a second driving part, the first driving part is used to drive the limiting sheath to move back and forth, and the second driving part is used to drive the wire separating knife to move back and forth.

[0009] In one embodiment, before the wire separating knife extends into the gap between the two pins, the part of the pin of the single-end glass-sealed thermistor close to the head is located in the limiting sheath. The limiting sheath contacts or approaches the pin before the wire separating knife, which can avoid the glass of the head being broken when the wire separating knife extends into the gap between the two pins.

[0010] In one embodiment, the lower supporting part is provided with a positioning groove, and the clamping part places the pin of the single-end glass-sealed thermistor in the positioning groove. The positioning groove can accurately position the position of the thermistor, and the wire separating knife can accurately extend into the gap between the two pins. BRIEF DESCRIPTION OF DRAWINGS

[0017] The structure of the pin separating device of the utility model and other aspects will be further described in detail in the following specific embodiments and with reference to the drawings.

[0018] As Figures 1 to 4 ​​​As shown, the utility model is used for single -end glass seal thermistor's branch pin device includes lower support 1, clamping part 2 and line cutter 3. Lower support 1 is used to support single -end glass seal thermistor 10, clamping part 2 is used to clamp single -end glass seal thermistor 10, and single -end glass seal thermistor 10 is delivered to lower support 1. Single -end glass seal thermistor 10 includes head 101 and two metal pins 102 arranged side by side, and head 101 is packaged with glass hot melting. Line cutter 3 extends between two pins along the direction perpendicular to the length of pin 102, so that two pins 102 are deformed to separate two pins 102 by a predetermined distance.

[0019] In specific embodiments, clamping part 2 includes upper clamp 21 and lower clamp 22, and upper clamp 21 and lower clamp 22 can approach or separate each other to open or close. Clamping part 2 clamps single -end glass seal thermistor 10 from other stations and delivers single -end glass seal thermistor 10 from other stations to lower support 1.

[0020] The utility model branch pin device still includes limit sheath 4, and limit sheath 4 is used to limit the separation distance of the part close to the head of pin 102, to avoid the part close to the head to break the packaging glass when separating. Limit sheath 4 is arranged side by side with line cutter 3, along the length direction of the pin 102 of single -end glass seal thermistor 10, and limit sheath 4 is located between line cutter 3 and clamping part 2. When the utility model branch pin device works, limit sheath 4 contacts or approaches pin 102 of single -end glass seal thermistor 10 earlier than line cutter 3.

[0021] In specific embodiments, as shown, Figure 5 Limit sheath 4 includes limit slot 41 for accommodating pin 102. When the utility model branch pin device works, limit sheath 4 moves towards pin 102 until pin 102 is located in limit slot 41. Correspondingly, first empty space 11 is provided on lower support 1, and first empty space 11 is used to accommodate the end of limit sheath 4 to enable pin 102 to be located in limit slot 41. The width of limit slot 41 is the same as or slightly larger than the width of two pins 102 of single -end glass seal thermistor 10. Lower support 1 is also provided with second empty space 12, and second empty space 12 is used to accommodate the end of line cutter 3 to facilitate line cutter 3 to extend between two pins 102.

[0022] In preferred embodiments, the upper surface of lower support 1 is provided with positioning groove 13, and clamping part 2 places pin 102 of single -end glass seal thermistor 10 in positioning groove 13, to facilitate line cutter 3 to accurately extend between two pins 102.

[0023] The utility model discloses a split pin device further includes first drive part 5 and second drive part 6, first drive part 5 is used for driving the reciprocating movement of limit sheath 4, and second drive part 6 is used for driving the reciprocating movement of split blade 3.
