Description

Technical Field

[0001] This invention relates to a lead-separating device for separating the two leads of a single-ended glass-sealed thermistor by a predetermined distance. This invention also relates to an automated device incorporating the aforementioned lead-separating device. Background Technology

[0002] Single-ended glass-sealed thermistors are common electronic components widely used in electrical automation equipment. They are soldered together with other electronic components. Before soldering, the two parallel leads of the single-ended glass-sealed thermistor need to be separated by a predetermined distance.

[0003] The two leads of a single-ended glass-sealed thermistor are made of metal and have a slender structure, making them prone to deformation. When processing a single-ended glass-sealed thermistor, the two slender leads arranged side by side tend to overlap vertically, preventing the wire splitter from being inserted between the two side-by-side leads during subsequent branching. Therefore, a technical solution is needed to ensure that the two leads can be arranged side-by-side so that the wire splitter can be easily inserted between them. Utility Model Content

[0004] The purpose of this invention is to provide a lead splitting device for a single-ended glass-sealed thermistor. This lead splitting device ensures that the two leads of the single-ended glass-sealed thermistor are in the same horizontal plane, thus facilitating the smooth insertion of a wire splitter between them.

[0005] To achieve the above objectives, the lead-separating device of this invention includes a lower support and a wire separator. The lower support supports the leads of the single-ended glass-sealed thermistor. The wire separator extends between the two leads in a direction perpendicular to the length of the leads to separate them by a predetermined distance. The lead-separating device also includes a first magnetic plate, which attracts the leads of the single-ended glass-sealed thermistor so that the two leads are in the same plane. The first magnetic plate is disposed at the lower support.

[0006] This utility model's lead splitting device uses a magnetic plate on the lower support to attract the two leads of a single-ended glass-sealed thermistor to the upper surface of the magnetic plate, thus placing them on the same horizontal plane. This avoids the two leads overlapping in the vertical direction, which facilitates the splitting blade extending between the two leads in a direction perpendicular to the length of the leads.

[0007] This utility model also provides an automated device for single-ended glass-sealed thermistors. The automated device includes a feeding device, a lead-separating device as described above, and a transfer device. The feeding device is used to automatically supply the single-ended glass-sealed thermistors one by one in an orderly manner. The transfer device is used to transport the single-ended glass-sealed thermistors from the feeding device to the lead-separating device.

[0008] This utility model's automated equipment uses a feeding device to systematically pick up individual single-ended glass-sealed thermistors from scattered pieces, and then uses a transfer device to transport the single-ended glass-sealed thermistors from the feeding device to a lead-separating device. The lead-separating device further separates the two leads of the single-ended glass-sealed thermistors by a fixed distance. The entire operation is automated and has a high success rate.

[0009] In a preferred embodiment, the automated equipment further includes a second magnetic plate, which is disposed at the feeding device and is used to attract the pins of the single-ended glass-sealed thermistor located on the feeding device so that the two pins are in the same plane.

[0010] In a preferred embodiment, the second magnetic plate is disposed on a support, which is capable of moving laterally in the horizontal direction along the length direction perpendicular to the pin to below the pin, and the support is capable of moving up and down to bring the second magnetic plate closer to or away from the pin.

[0011] In a preferred embodiment, the transfer device includes a turntable and a clamping part disposed on the turntable, the clamping part being used to clamp the pins of the single-ended glass-sealed thermistor.

[0012] In a preferred embodiment, a plurality of clamping portions are evenly arranged along the circumference of the turntable. Attached Figure Description

[0020] The following detailed description, with reference to the accompanying drawings, further illustrates the structure and other aspects of the automated equipment and lead-separating device of this utility model.

[0021] like Figure 1 As shown, the automated equipment for single-ended glass-sealed thermistors of this invention includes a feeding device 1, a transfer device 2, and a lead-separating device 3. The feeding device 1 is used to orderly pick up scattered single-ended glass-sealed thermistors 10 one by one. The transfer device 2 is used to transport the single-ended glass-sealed thermistors 10 from the feeding device 1 to the lead-separating device 3 one by one. The lead-separating device 3 is used to separate the two side-by-side leads of the single-ended glass-sealed thermistor 10 by a predetermined distance. Figure 2 As shown, the single-ended glass-sealed thermistor 10 includes a head 101 and two pins 102 arranged side by side.

[0022] like Figure 3 As shown, the feeding device 1 includes a feeding device 11, a picking clamp 12, a transfer wheel 13, and a posture conversion device 14. The feeding device 11 is used to gather scattered single-ended glass-sealed thermistors 10 at a specific location. The picking clamp 12 is used to remove individual single-ended glass-sealed thermistors 10 from the gathered single-ended glass-sealed thermistors 10. The picking clamp 12 can move left and right horizontally and up and down vertically. The transfer wheel 13 is used to remove the single-ended glass-sealed thermistors 10 from the picking clamp 12. The posture conversion device 14 is used to switch the single-ended glass-sealed thermistors 10 from a horizontal posture to a vertical posture.

[0023] The feeding device 11 includes a pair of parallel plates 111 and magnetic blocks 112, forming a feeding channel 113 between the plates 111. The magnetic blocks 112 are located on the side of the plates 111 opposite to the feeding channel 113. Two magnetic blocks 112 are provided on one side of each plate 111, arranged in a V-shape. The top of the V-shape is close to the plate 111. The magnetic field of the V-shaped magnetic blocks 112 on the sides of the plates 111 attracts single-ended glass-sealed thermistors 10 to the center of the feeding channel 113, corresponding to the top of the V-shape. When a large number of scattered single-ended glass-sealed thermistors 10 are placed in the feeding channel 113, they are concentrated in the center of the feeding channel 113 under the influence of the magnetic field.

[0024] The material handling fixture 12 includes a suction nozzle 121, which can move horizontally left and right and vertically up and down. When the material handling fixture 12 is working, the suction nozzle 121 extends into the feeding channel 113, and the position of the suction nozzle 121 corresponds to the head 101 of the single-ended glass-sealed thermistor 10. When the suction nozzle 121 contacts or approaches the head 101, it picks up the single-ended glass-sealed thermistor 10.

[0025] A posture conversion element 14 is provided above the feeding channel 113. The posture conversion element 14 is used to switch the single-ended glass-sealed thermistor 10 from a horizontal posture to a vertical posture. In a specific embodiment, the posture conversion element 14 has a U-shaped structure, with one side fixed to one of the flat plates 111 and the other side suspended above the feeding channel 113. When the suction nozzle 121 moves upward in the vertical direction, the single-ended glass-sealed thermistor 10 is in a horizontal posture. When the single-ended glass-sealed thermistor 10 moves to the position of the posture conversion element 14, the pin 102 of the single-ended glass-sealed thermistor 10 is blocked by the posture conversion element 14. The suction nozzle 121 continues to move upward, and the single-ended glass-sealed thermistor 10 changes from a horizontal posture to a vertical posture under the magnetic field of the posture conversion element 14 and the magnetic block 112 below.

[0026] For a more detailed description of the structure and working principle of the feeding device, please refer to the applicant's Chinese Patent Application No. CN2024232599557, the contents of which are incorporated herein by reference. Further details are omitted here.

[0027] The transfer wheel 13 includes multiple magnetic arms 131 for attracting single-ended glass-sealed thermistors 10. Magnetic blocks are embedded in the magnetic arms 131 for attracting the head and / or leads of the single-ended glass-sealed thermistors. Clearance positions 132 are provided on the magnetic arms 131. The pick-up clamp 12 moves horizontally toward the magnetic arms 131. When the leads 102 of the single-ended glass-sealed thermistor 10 approach the magnetic arms 131, they are attracted by the magnetic blocks on the arms 131. After the nozzle 121 separates from the head 101 of the single-ended glass-sealed thermistor 10, the nozzle 121 picks up the next single-ended glass-sealed thermistor 10. The transfer wheel 13 rotates 90 degrees, waiting to receive the next single-ended glass-sealed thermistor 10.

[0028] like Figure 4 As shown, after the transfer wheel 13 rotates 90 degrees, the single-ended glass-sealed thermistor 10 switches from a vertical state to a horizontal state. This utility model's automated equipment also includes a magnetic plate 4 (a second magnetic plate), which is mounted on a support 41. The support 41 can move laterally in the horizontal direction along the length perpendicular to the pin 102 to below the pin 102, and it can also move up and down to approach or move away from the pin 102. Specifically, when the support 41 moves laterally, the end of the support 41 and the magnetic plate 4 can extend into the clearance position 132. When the magnetic plate 4 moves upward towards the pin 102, the two pins 102 are attracted to the upper surface of the magnetic plate 4 under its magnetic attraction, thus placing them on the same horizontal plane.

[0029] like Figure 1As shown, the transfer device 2 includes a turntable 21 and a clamping part 22 mounted on the turntable 21. The clamping part 22 can move circumferentially under the drive of the turntable 21. The clamping part 22 is used to clamp the leads 102 of the single-ended glass-sealed thermistor 10. The clamping part 22 includes an upper clamp 221 and a lower clamp 222, which can move vertically to achieve closure or opening. The transfer device 2 is used to transfer the single-ended glass-sealed thermistor 10 from the loading device 1 to the lead-separating device 3. After the magnetic plate 4 attracts the two leads 102 to its upper surface, so that the leads 102 are in the same horizontal plane, the clamping part 22 clamps the two leads 102 and ensures that the clamped part is in the horizontal plane. The end of the bracket 41 and the magnetic plate 4 retract from the clearance position 132. The turntable 21 rotates, rotating the clamping part 22 from the loading device 1 to the lead-separating device 3.

[0030] like Figure 5 and Figure 6 As shown, the lead splitting device 3 includes a lower support 31, a splitter 32, and a frame 30. The lower support 31 and the splitter 32 are movably mounted on the frame 33. Further, the splitter 32 is mounted on a bracket 35, which can move the splitter 32 up and down under the drive of a drive unit (not shown). The lower support 31 supports the single-ended glass-sealed thermistor 10. The splitter 32 can extend between the two leads in a direction perpendicular to the length of the lead 102, causing the two leads 102 to deform and separate them by a predetermined distance. The lead splitting device 3 also includes a magnetic plate 33 (first magnetic plate), which attracts the leads 102 of the single-ended glass-sealed thermistor 10 so that the two leads 102 are in the same plane. The magnetic plate 33 is disposed at the lower support 31. The lower support 31 can move the magnetic plate 33 up and down under the drive of the drive unit.

[0031] The clamping part 22 transports the single-ended glass-sealed thermistor 10 from the feeding device 1 to the splitting device 3. Specifically, the single-ended glass-sealed thermistor 10 is moved above the lower support part 31 and the magnetic plate 33. The lower support part 31 moves the magnetic plate 33 upward until the magnetic plate 33 contacts the pins 102. The pins 102 are attracted to the upper surface of the magnetic plate 33, so that the two pins 102 are in the same plane. The splitting blade 32 moves downward under the drive of the bracket 35 and extends between the two pins 102, thereby separating the two pins 102. Since the pins 102 are made of metal, the splitting blade 32 causes the pins 102 to deform after extending between the two pins 102, thus forming a fixed gap between the two pins. The lower support part 31 and the splitting blade 32 return to their initial positions, and the transfer device 2 continues to rotate. This cycle can automatically separate the pins of the single-ended glass-sealed thermistor 10 one by one.

[0032] The above embodiments are only used to illustrate the concept and scope of this utility model and are not intended to limit the protection scope of this utility model. Modifications, equivalent substitutions, and other improvements to the above embodiments that are obvious to those skilled in the art are also within the concept of this utility model. The protection scope and concept of this utility model are specifically defined by the claims.
