Description

Technical Field

[0001] This utility model relates to the field of positioning device technology, and more specifically, it relates to a PTC thermistor welding positioning device. Background Technology

[0002] In existing technologies, the device cannot flexibly adjust the angle of the thermistor during use. This means that when operators or automated systems are positioning and soldering PTC thermistors, they may encounter difficulties if they need to adjust the angle of the component to adapt to a specific layout or soldering point on the circuit board. Due to the lack of a flexible angle adjustment mechanism, operators may need to manually reposition the thermistor or adjust the position of the entire device, which not only increases the complexity of operation but may also affect the soldering quality and production efficiency.

[0003] Secondly, the existing equipment suffers from a slow process in releasing the stabilizing pads. The stabilizing pads are used during welding to maintain the stability of the PTC thermistor and prevent vibration or external forces from affecting welding accuracy. However, if the operator cannot quickly release the stabilizing pads after the welding process is complete, this will prolong the time of each welding cycle and reduce the overall efficiency of the production line.

[0004] Finally, existing equipment also shows inefficiency in the process of fixing the stabilizing pad and the stabilizing plate. The stabilizing plate is usually used as a support structure with the stabilizing pad to ensure high stability during the welding process. If the fixing process is slow or the mechanism is complicated, it will not only increase the time of a single welding, but may also cause welding quality problems due to improper fixing.

[0032] Please see Figures 1-6 A PTC thermistor welding positioning device includes a fixed frame 1, on which a clamping assembly is provided. The clamping assembly includes a mounting frame 2, a rotating seat 3, an operating plate 4, a fixed seat 5, and a stabilizing seat 6. The mounting frame 2 is located at one end of the fixed frame 1. The rotating seat 3 is rotatably connected to the mounting frame 2 and the fixed frame 1. The operating plate 4 is mounted on the rotating seat 3. The fixed seat 5 is fixedly mounted on the operating plate 4. The stabilizing seat 6 is slidably connected to the fixed seat 5. The stabilizing seat 6 is provided with a disassembly and assembly assembly, which includes a stabilizing pad 7, a fixing sleeve 8, and an insertion rod 9. The stabilizing pad 7 is detachably mounted on the stabilizing seat 6. The fixing sleeve 8 is fixedly mounted on the stabilizing seat 6. The insertion rod 9 is slidably connected to the stabilizing pad 7 and the stabilizing seat 6.

[0033] A mounting base 10 is installed on the fixed base 5. A threaded rod 11 is threadedly connected to the mounting base 10. One end of the threaded rod 11 is rotatably connected to the stable base 6. A motor 12 and a coupling 13 are installed on the fixed frame 1. The output end of the motor 12 is connected to the coupling 13.

[0034] A drive wheel 14 is connected to the coupling 13, and a driven wheel 15 is connected to one end of the rotating seat 3. The driven wheel 15 is meshed with the drive wheel 14. A welding assembly 16 is installed on the mounting bracket 2.

[0035] One end of the insertion rod 9 is connected to a stop plate 17, which is in close contact with the stabilizing pad 7. A rotating ring 18 is rotatably connected to the fixing sleeve 8, and a guide rod 19 is connected to the rotating ring 18. A sliding plate 20 is slidably connected to the guide rod 19.

[0036] A first spring 21 is sleeved on the guide rod 19. The two ends of the first spring 21 are connected to the sliding plate 20 and the rotating ring 18. A movable sleeve 22 is slidably connected on the fixed sleeve 8. A tension spring 23 is connected between the movable sleeve 22 and the fixed sleeve 8. A through hole 24 is opened on the movable sleeve 22, and the through hole 24 is adapted to the guide rod 19.

[0037] In this embodiment, during use, the thermistor is placed on the operating panel 4, and the threaded rod 11 is rotated to move the stabilizing seat 6 along the fixed seat 5, thereby fixing the thermistor in place. Then, the motor 12 is started, which drives the driving wheel 14 to rotate via the coupling 13, causing the driven wheel 15 to rotate. This causes the rotating seat 3 to rotate along the mounting bracket 2 and the fixed bracket 1. After adjusting it to a suitable angle, the welding assembly on the mounting bracket 2 is used... 16. During the welding process, when the stabilizing pad 7 needs to be replaced after a period of use, the rotating ring 18 is rotated along the fixed sleeve 8. When the rotating ring 18 rotates the guide rod 19 to be aligned with the through hole 24 on the movable sleeve 22, the movable sleeve 22 is driven to slide along the fixed sleeve 8 under the elastic potential energy of the tension spring 23. During the sliding movement, the sliding plate 20 is driven to slide along the guide rod 19. During the sliding movement, the first spring 21 is compressed, so that the guide rod 19 passes through the through hole 24.

[0038] Please see Figure 5-6As an embodiment of a PTC thermistor welding positioning device for a locking component: a locking component is provided on the fixed sleeve 8. The locking component includes a second spring 25, an abutment plate 26 and a sliding rod 27. The second spring 25 is connected to the inside of the fixed sleeve 8, the abutment plate 26 is connected to the second spring 25, the abutment plate 26 is in close contact with one end of the insertion rod 9, and the sliding rod 27 is slidably connected to the fixed sleeve 8.

[0040] The insertion rod 9 has an insertion slot 30, which is adapted to the insertion block 28.

[0041] More specifically, during the movement of the movable sleeve 22, the inner side of the sleeve releases its contact with the sliding rod 27, causing the insertion block 28 to move out of the insertion slot 30 under the elastic potential energy of the third spring 29, thereby releasing the fixing process of the insertion rod 9. At this time, the insertion rod 9 is slid out along the stabilizing pad 7 and the stabilizing seat 6, thereby removing the stabilizing pad 7 and completing the replacement process. The above operation is then performed in reverse to complete the replacement process of the stabilizing pad 7.

[0042] In summary, during the use or operation of the overall equipment: During use, the thermistor is placed on the operating panel 4, and the threaded rod 11 is rotated to move the stabilizing seat 6 along the fixed seat 5, thus securing the thermistor. Next, the motor 12 is started, driving the drive wheel 14 via the coupling 13 to rotate, which in turn rotates the driven wheel 15, causing the rotating seat 3 to rotate along the mounting frame 2 and the fixed frame 1. After adjusting it to a suitable angle, the mounting frame 2... The welding assembly 16 is welded. When the stabilizing pad 7 needs to be replaced after a period of use, the rotating ring 18 is rotated along the fixed sleeve 8. When the guide rod 19 is rotated to align with the through hole 24 on the moving sleeve 22, the moving sleeve 22 is driven to slide along the fixed sleeve 8 under the elastic potential energy of the tension spring 23. During the sliding movement, the sliding plate 20 is driven to slide along the guide rod 19. During the sliding movement, the first spring 21 is compressed, so that the guide rod 19 passes through the through hole 24.

[0043] During the movement of the movable sleeve 22, the inner side of it releases the contact with the sliding rod 27, causing the insertion block 28 to move out of the insertion slot 30 under the elastic potential energy of the third spring 29, thereby releasing the fixing process of the insertion rod 9. At this time, the insertion rod 9 is slid out along the stabilizing pad 7 and the stabilizing seat 6, thereby removing the stabilizing pad 7 and completing the replacement process. The above operation is then performed in reverse to complete the replacement process of the stabilizing pad 7.

[0044] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred.
