[0020] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.
[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0022] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 As shown, the circuit board fuse device of the inspection and winding machine of the present invention mainly includes a circuit board body 1, the upper surface of the circuit board body 1 is fixedly connected to the lower horizontal plate 2, the upper surface of the lower horizontal plate 2 is fixedly connected to the U-shaped plate 3, the left and right sides of the U-shaped plate 3 are respectively provided with a first circular hole 4, the inner wall of the first circular hole 4 is fixedly connected to an arc-shaped conductive plate 5, the upper surface of the arc-shaped conductive plate 5 and the inner wall of the first circular hole 4 are both fitted with a fuse body 6, the left and right sides of the fuse body 6 and the surface of the U-shaped plate 3 are both fitted with a limiting ring 7, the left and right sides of the inner wall of the limiting ring 7 are fixedly connected to an upper horizontal plate 8, the bottom of the upper horizontal plate 8 and the upper surface of the lower horizontal plate 2 are both fixedly connected with a spring 9, and the upper surface of the circuit board body 1 is fixedly connected to the first terminal Sub-10, the upper surface of the circuit board body 1 is fixedly connected with the second terminal 11, and the left and right sides of the U-shaped plate 3 are provided with a second circular hole 12. The inner wall of the first terminal 10, the inner wall of the second terminal 11, the inner wall of the second circular hole 12 and the bottom of the arc-shaped conductive plate 5 are fixedly connected with a conductive column 13. The upper surface of the U-shaped plate 3 is provided with an observation hole 18, and the observation hole 18 is located directly above the fuse body 6. The upper surface of the limiting ring 7 is provided with an arc groove 19, and the arc groove 19 is located on the right side of the fuse body 6. The diameter of the arc groove 19 is equal to the diameter of the fuse body 6. The top of the inner wall of the U-shaped plate 3 is fixedly connected with a pressing spring 20, and the bottom of the pressing spring 20 is in contact with the upper surface of the fuse body 6.
[0023] When the fuse body 6 is inserted into the first circular hole 4, the elastic force of the spring 9 makes both ends of the fuse body 6 fit with the inner wall of the limiting ring 7, and the limiting ring 7 fixes the fuse body 6 on the arc-shaped conductive plate 5. At this time, through the cooperation of the arc-shaped conductive plate 5 and the conductive column 13, the first terminal 10 and the second terminal 11 are electrically connected to the fuse body 6. Then, the first terminal 10 is connected to the terminal on the circuit board body 1, and the second terminal 11 is connected to the terminal on the solenoid valve coil. At this time, the solenoid valve coil is connected to the circuit board body 1 through the fuse body 6, and is connected to the circuit board body 1 through the fuse body 6. When the solenoid valve coil fails through the fuse body 6, the circuit board body 1 will not burn out. When the limit ring 7 is offset from the fuse body 6, the fuse body 6 can be directly moved out of the first circular hole 4. When the fuse body 6 is in contact with the arc groove 19, the arc groove 19 can be used to position the fuse body 6, and the axis of the fuse body 6 is located directly above the center of the first circular hole 4. When the fuse body 6 is inserted into the first circular hole 4, the elastic force of the pressing spring 20 is used to make the fuse body 6 and the arc-shaped conductive plate 5 in close contact. At the same time, the user can observe whether the fuse body 6 is damaged through the observation hole 18.
[0024] The right side of the retaining ring 7 is fixedly connected to a support plate 14. A rubber sleeve 15 is fitted onto the surface of the support plate 14. Positioning plates 16 are bonded to the upper and lower sides of the rubber sleeve 15. A groove 17 is formed on the side of the U-shaped plate 3 near the upper horizontal plate 8. The inner wall of the groove 17 is fitted into the surface of the positioning plate 16. The friction between the rubber sleeve 15 and the support plate 14 is greater than the combined weight of the positioning plate 16 and the rubber sleeve 15. Due to the friction between the rubber sleeve 15 and the support plate 14, the positioning plate 16 is fixed within the groove 17 after the rubber sleeve 15 is fitted onto the support plate 14. The cooperation between the positioning plate 16 and the groove 17 also locks the retaining ring 7. This prevents maintenance personnel from accidentally touching the support plate 14 when repairing the circuit board body 1, which could cause the retaining ring 7 to separate from the fuse body 6 and the fuse body 6 to detach from the U-shaped plate 3.
[0025] The working principle of the present invention is as follows: first, the fuse tube body 6 is fitted with the arc groove 19, then, the limit ring 7 is moved downward by pressing the fuse tube body 6, and when the fuse tube body 6 is aligned with the first circular hole 4, the fuse tube body 6 is inserted into the first circular hole 4 by moving the fuse tube body 6 horizontally, and the elastic force of the pressing spring 20 is used to make the fuse tube body 6 and the arc-shaped conductive plate 5 in close contact.
[0026] When the left and right ends of the fuse body 6 are aligned with the left and right sides of the U-shaped plate 3, the limit ring 7 is moved up by the elastic force of the spring 9, and the fuse body 6 is fixed on the arc-shaped conductive plate 5 by the limit ring 7. At this time, through the cooperation of the arc-shaped conductive plate 5 and the conductive column 13, the first terminal 10 and the second terminal 11 are electrically connected to the fuse body 6. Then, the first terminal 10 is connected to the terminal on the circuit board body 1, and the second terminal 11 is connected to the terminal on the solenoid valve coil. At this time, the solenoid valve coil is connected to the circuit board body 1 through the fuse body 6, and through the fuse body 6, when the solenoid valve coil fails, the circuit board body 1 will not burn out.
[0027] When the fuse body 6 is damaged, first fit a new fuse body 6 into the arc groove 19, then press the fuse body 6 to move the limit ring 7 downward. When the new fuse body 6 is aligned with the old fuse body 6, push the new fuse body 6 to the left to remove the old fuse body 6 from the U-shaped plate 3, and push the new fuse body 6 into the first circular hole 4.
[0028] When the left and right ends of the new fuse body 6 are aligned with the left and right sides of the U-shaped plate 3, the elastic force of the spring 9 causes the limit ring 7 to move upward and fix the new fuse body 6 on the arc-shaped conductive plate 5 through the limit ring 7.
[0029] After the fuse body 6 is fixed on the arc-shaped conductive plate 5, the rubber sleeve 15 is put on the support plate 14, so that the positioning plate 16 is fixed in the groove 17 under the action of the friction between the rubber sleeve 15 and the support plate 14. The positioning plate 16 and the groove 17 cooperate to lock the limit ring 7. When the fuse body 6 needs to be replaced, the positioning plate 16 is removed from the groove 17 to release the lock of the limit ring 7.
[0030] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
