Description

Technical Field

[0001] This application relates to the field of welding apparatus, and more particularly to an online welding system using a wheel speed sensor. Background Technology

[0002] Wheel speed sensors are commonly used electronic sensors, acting like a "pulse monitor" for equipment. They can detect changes in the rotational speed of equipment in real time and with high accuracy. Widely used in various mechanical and electronic devices, they are used to detect and monitor the rotational speed of rotating bodies. They provide crucial data support for the normal operation and performance optimization of equipment, playing a vital role in equipment control, performance optimization, and fault diagnosis.

[0003] As per the instruction manual Figure 5 The wheel speed sensor shown is welded by melting the plastic part to fix the two chip pins. The existing welding method usually involves manually holding the wheel speed sensor and then using a hot melt device for welding, which can easily lead to hand burns. At the same time, uneven pressure during hot melt can also cause the plastic part to not be properly fixed to the chip pins after melting. Utility Model Content

[0004] To address the issue of hand burns caused by manually welding wheel speed sensors using a hot melt device, this application provides an online welding system for wheel speed sensors.

[0005] The online welding system for wheel speed sensors provided in this application adopts the following technical solution: It includes a base, a connecting box fixed to one side of the base via a second connecting rod, a support column fixed to the top of the base, a top plate fixed to the top of the support column, a turntable rotatably connected to the outer wall of the support column, a limit mechanism provided on the top of the turntable, a support seat fixed to the top of the top plate, a first telescopic cylinder fixed to one side of the support seat, a first connecting rod fixed to the power output end of the first telescopic cylinder, a pressing block fixed to the bottom of one end of the first connecting rod, a connecting block fixed to one side of the connecting box, a second telescopic cylinder fixed through the top of the connecting block, and a hot melt block fixed to the power output end of the second telescopic cylinder.

[0006] By adopting the above technical solution, the hot melt block is energized, generating heat that can melt the plastic parts.

[0007] Preferably, the inner wall of the support column is provided with a driving mechanism, which is a stepper motor, and the rotation of the turntable is controlled by the stepper motor.

[0008] By adopting the above technical solution, the turntable can be driven to rotate by a stepper motor, so that the turntable can stop immediately and the limiting mechanism can be located directly below the extrusion block.

[0009] Preferably, multiple limiting mechanisms are provided, and the multiple limiting mechanisms are arranged equidistantly in a circle. Each limiting mechanism includes a placement block, and the placement block is arranged in an L-shape.

[0010] By adopting the above technical solution, a sensor body can be placed on the top of each limiting mechanism. When the sensor body on the top of one limiting mechanism is welded, a sensor body can be placed on the top of another limiting mechanism.

[0011] Preferably, the top of the placement block has grooves on both sides of the center, and a threaded rod is threaded through the center of one end of the placement block. A knob is fixed to one end of the threaded rod, and a limit block is rotatably connected to the other end of the threaded rod.

[0012] By adopting the above technical solution, the position of the limiting block is adjusted by rotating the knob to drive the threaded rod to rotate, thereby adjusting the position of the plastic part after the sensor body is placed on top of the placement block, so that it is exactly below the hot melt block. The groove is used in conjunction with the slider at the bottom of the sensor body, so that the sensor body can be better connected to the placement block.

[0013] Preferably, the hot melt block and the first telescopic cylinder are located in the same vertical plane, and the bottom of the hot melt block and the top of the turntable are located in the same horizontal plane.

[0014] By adopting the above technical solution, by controlling the extension of the second hydraulic telescopic rod, the hot melt block is moved to the bottom to hot melt the plastic part of the sensor body on the top of the placement block above the turntable.

[0015] Preferably, the extrusion block is located directly above the end of the placement block near the connecting box, and the bottom end of the extrusion block is horizontally positioned.

[0016] By adopting the above technical solution, the first hydraulic telescopic rod drives the first connecting rod to move downward, thereby causing the extrusion block to extrude the sensor body on top of the placement block, preventing the sensor body from falling off during heat melting.

[0017] Preferably, an exhaust pipe is fixed to one side of the connecting box by a strap, and the bottom end of the exhaust pipe is located on one side of the bottom end of the hot melt block.

[0018] By adopting the above technical solution, the toxic and harmful gases generated by the hot-melt plastic parts are extracted to the outside through the exhaust pipe connected to an external exhaust fan.

[0019] In summary, this application includes at least the following beneficial technical effects: 1. This application places the sensor body on top of the placement block, and the groove is used in conjunction with the slider at the bottom of the sensor body, so that the sensor body can be better connected to the placement block. The stepper motor drives the turntable to rotate, and the placement block with the sensor body is rotated to the bottom of the extrusion block. The extension of the second hydraulic telescopic rod is controlled to move the hot melt block to the bottom, so as to heat melt the plastic part of the sensor body on the top of the placement block above the turntable. This achieves the effect of avoiding hand contact with the hot melt part and preventing burns. 2. This application achieves a higher welding yield by moving the first connecting rod downwards via the first hydraulic telescopic rod during welding, thereby causing the extrusion block to press against the sensor body on top of the placement block, preventing the sensor body from falling during hot melting. This keeps the sensor body horizontal and prevents it from moving arbitrarily during welding, allowing hot melting welding to be performed directly above, thus achieving a higher welding yield.

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0022] This application discloses an online welding system for wheel speed sensors, including a base 1. A connecting box 10 is fixed to one side of the base 1 via a second connecting rod 9. A support column 2 is fixed to the top of the base 1, and a top plate 3 is fixed to the top of the support column 2. A turntable 4 is rotatably connected to the outer wall of the support column 2. A limit mechanism is provided on the top of the turntable 4. A support seat 5 is fixed to the top of the top plate 3. A first telescopic cylinder 6 is fixed to one side of the support seat 5. The first telescopic cylinder 6 controls the extrusion of the extrusion block 8. A first connecting rod 7 is fixed to the power output end of the first telescopic cylinder 6. The extrusion block 8 is fixed to the bottom of one end of the first connecting rod 7. A connecting block 13 is fixed to one side of the connecting box 10. A second telescopic cylinder 14 is fixed through the top of the connecting block 13. The second telescopic cylinder 14 controls the movement of the hot melt block 15. The hot melt block 15 is fixed to the power output end of the second telescopic cylinder 14. By energizing the hot melt block 15, the hot melt block 15 generates heat that can melt the plastic part 24.

[0023] Reference Appendix Figure 1 The inner wall of the support column 2 is equipped with a drive mechanism, which is a stepper motor. The stepper motor controls the rotation of the turntable 4, and the turntable 4 can be stopped immediately by the stepper motor, so that the limiting mechanism can be located directly below the extrusion block 8.

[0024] Reference Appendix Figure 1 The device includes multiple limiting mechanisms arranged equidistantly in a circle. Each limiting mechanism includes a placement block 16, which is L-shaped. A sensor body 21 can be placed on the top of each limiting mechanism. When welding the sensor body 21 on the top of one limiting mechanism, a sensor body 21 can be placed on the top of another limiting mechanism.

[0025] Reference Appendix Figure 4 The top of the placement block 16 has grooves 17 on both sides. A threaded rod 19 is threaded through the middle of one end of the placement block 16. A knob 20 is fixed to one end of the threaded rod 19, and a limit block 18 is rotatably connected to the other end of the threaded rod 19. By rotating the knob 20, the threaded rod 19 is rotated to adjust the position of the limit block 18, thereby adjusting the position of the plastic part 24 after the sensor body 21 is placed on top of the placement block 16, so that it is exactly below the hot melt block 15. The grooves 17 are used in conjunction with the slider 22 at the bottom of the sensor body 21, so that the sensor body 21 can be better connected to the placement block 16.

[0026] Reference Appendix Figure 1 The hot melt block 15 and the first telescopic cylinder 6 are located on the same vertical plane, and the bottom of the hot melt block 15 and the top of the turntable 4 are located on the same horizontal plane. By controlling the extension of the second hydraulic telescopic rod 14, the hot melt block 15 is moved to the bottom to heat melt the plastic part 24 of the sensor body 21 on the top of the placement block 16 above the turntable 4.

[0027] Reference Appendix Figure 1 and 3 The extrusion block 8 is located directly above the end of the placement block 16 near the connecting box 10. The bottom of the extrusion block 8 is horizontally positioned. The first connecting rod 7 is moved downward by the first hydraulic telescopic rod 6, which causes the extrusion block 8 to extrude the sensor body 21 on the top of the placement block 16 to prevent the sensor body 21 from falling off during heat melting.

[0028] Reference Appendix Figure 2 The connecting box 10 has an exhaust pipe 11 fixed to one side by a strap 12. The bottom end of the exhaust pipe 11 is located on one side of the bottom end of the hot melt block 15. The exhaust pipe 11 is connected to an external exhaust fan to extract the toxic and harmful gases generated by the hot melt plastic part 24 to the outside.

[0029] The implementation principle of the wheel speed sensor online welding system in this application embodiment is as follows: First, the position of the limiting block 18 is adjusted according to the length of the sensor body 21 and the position to be heat-melted. By rotating the knob 20, the threaded rod 19 is rotated, thereby adjusting the position of the sensor body 21 after the plastic part 24 is placed on the top of the placement block 16, so that it is exactly below the heat-melting block 15. Then, the sensor body 21 is placed on the top of the placement block 16. The groove 17 is used in conjunction with the slider 22 at the bottom of the sensor body 21, so that the sensor body 21 can be better connected to the placement block 16. The motor drives the turntable 4 to rotate, so that the turntable 4 can stop immediately, keeping the limiting mechanism directly below the extrusion block 8. The placement block 16, on which the sensor body 21 is placed, is rotated to the bottom of the extrusion block 8. Then, the first connecting rod 7 is moved downward by the first hydraulic telescopic rod 6, causing the extrusion block 8 to extrude the sensor body 21 on the top of the placement block 16 to prevent the sensor body 21 from falling off during heat melting. Finally, the extension of the second hydraulic telescopic rod 14 is controlled to move the heat melting block 15 to the bottom, so that the plastic part 24 of the sensor body 21 on the top of the placement block 16 above the turntable 4 can be heat melted.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
