Description

Technical Field

[0001] The utility model relates to the technical field of AGV trolleys, in particular to an electrostatic treatment tool for an AGV trolley on a ground film. Background Art

[0002] With the rapid development of factory automation and computer integrated manufacturing technology, AGV is a necessary automated handling and loading and unloading method to connect and adjust discrete logistics management systems to make their operations continuous. Due to its high degree of automation, AGV carts are widely used for automatic logistics handling and transfer in photovoltaic silicon wafer manufacturing.

[0003] Over time, the wheels of AGVs can scratch the epoxy floor, so an anti-scratch film was installed. However, static electricity is generated when the AGVs connect to the machine, and this static electricity cannot be effectively dissipated when the AGVs operate on the film. This often causes operators to experience a tingling sensation when they touch the AGVs. Utility Model Content

[0025] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] See also Figure 1-8The utility model provides an electrostatic treatment tool for an AGV trolley on a ground film, comprising a T-shaped metal sheet 2 bonded to the ground film 1 and a mounting disc 4 mounted on the lower surface of the AGV trolley 3 by bolts. The square side of the T-shaped metal sheet 2 is bonded to the upper surface of the ground film 1 close to the machine platform by conductive glue. The long side of the T-shaped metal sheet 2 extends to the outside of the ground film 1 and is bonded to the ground on the lower surface of the machine platform by conductive glue. The lower surface of the mounting disc 4 is connected with a telescopic rod 5, and the lower end of the telescopic rod 5 is connected with an elastic contraction rod 6. The lower end of the elastic contraction rod 6 is connected with a fixed disc 7. The fixed disc 7 and the mounting disc 4 are connected by a conductive wire 8. The lower surface of the fixed disc 7 is fixedly connected to a metal universal ball wheel 9. When the AGV trolley 3 is docked with the machine platform, the lower surface of the metal universal ball wheel 9 contacts the upper surface of the square side of the T-shaped metal sheet 2.

[0027] By providing a T-shaped metal plate 2, this utility model effectively transfers static electricity generated when the AGV trolley 3 docks with the machine to the ground. Specifically, when the AGV trolley 3 docks with the machine, the static electricity generated is transferred to the fixed disc 7 and the metal universal ball wheel 9 via the mounting disc 4 and the conductive wire 8. At this point, the metal universal ball wheel 9 contacts the square upper surface of the T-shaped metal plate 2, transferring the static electricity through the T-shaped metal plate 2 to the ground, effectively eliminating static electricity.

[0028] Specifically, the overall length of the telescopic rod 5 can be adjusted according to actual usage to adapt to AGV carts 3 with different chassis heights; the function of the elastic retractable rod 6 is to give the fixed disc 7 a downward elastic force, so that the metal universal ball wheel 9 can fully and effectively contact the T-shaped metal sheet 2, ensuring that static electricity can be transferred to the ground through the T-shaped metal sheet 2 and be eliminated.

[0029] Specifically, the square side of the T-shaped metal sheet 2 contacts the metal universal ball wheel 9. The larger square side of the T-shaped metal sheet 2 increases the contact area between the two, thereby improving the reliability of static elimination. The long side of the T-shaped metal sheet 2 extends to the outside of the ground film 1 and connects to the ground. The long side primarily serves to transfer static electricity to the ground. The T-shaped structure provides a larger contact surface, which not only helps to stably adhere to the ground film 1, but also minimizes the manufacturing cost of the T-shaped metal sheet 2.

[0030] Specifically, conductive wire 8 connects mounting disc 4 and fixed disc 7, ensuring stable static electricity transmission. Since the lengths of telescopic rod 5 and elastic retractable rod 6 between mounting disc 4 and fixed disc 7 are adjustable, this could affect static electricity transmission. By connecting mounting disc 4 and fixed disc 7 via conductive wire 8, the stable static electricity transmission remains unchanged regardless of how the lengths of telescopic rod 5 and elastic retractable rod 6 are adjusted.

[0031] Specifically, the ball wheel of the metal universal ball wheel 9 can rotate 360 ​​degrees, which allows it to automatically adjust its direction according to the operation of the AGV trolley 3. The metal universal ball wheel 9 is a prior art and will not be described in detail herein.

[0032] Furthermore, the T-shaped metal sheet 2 adopts an aluminum foil metal sheet 21, and a copper wire 22 is bonded to the lower surface of the aluminum foil metal sheet 21. The copper wire 22 is distributed in a serpentine shape on the lower surface of the square side of the aluminum foil metal sheet 21, and one end of the copper wire 22 extends along the long strip side of the aluminum foil metal sheet 21 to the outside of the ground film 1.

[0033] Specifically, both the aluminum foil sheet 21 and the copper wire 22 have strong electrical conductivity, and their combination further enhances the conductive effect. The aluminum foil sheet 21, through its large contact surface, can quickly collect and transfer static electricity, while the copper wire 22 provides a stronger conductive path at the contact point, effectively directing static electricity to the ground, thereby effectively eliminating static electricity. The copper wire 22 is arranged in a serpentine pattern on the lower surface of the square side of the aluminum foil sheet 21 to increase contact points and facilitate the rapid discharge of static electricity.

[0034] Furthermore, the telescopic rod 5 includes an outer tube 51 with an opening at the lower end and an inner tube 52. The outer tube 51 is fixedly connected to the lower surface of the mounting disc 4, and the inner tube 52 is slidably connected to the inner lower end of the outer tube 51. The outer tube 51 and the inner tube 52 are fixed by a locking bolt 53. Threaded holes 511 are formed on both sides of the tube wall of the outer tube 51, and side grooves 521 are formed on both sides of the outer wall of the inner tube 52. The locking bolts 53 are threaded through the interior of the threaded holes 511 and abut against the side grooves 521.

[0035] Specifically, the overall length of the telescopic rod 5 can be adjusted based on the actual distance between the bottom of the AGV trolley 3 and the ground film 1 to ensure reliable contact between the metal universal ball wheel 9 and the ground film 1. Adjustment process: Loosen the locking bolt 53 to allow the inner cylinder 52 and the outer cylinder 51 to slide relative to each other. By adjusting the position of the inner cylinder 52 and the outer cylinder 51, ensure that the metal universal ball wheel 9 is in contact with the ground film 1. After adjusting to the appropriate position, re-tighten the locking bolt 53 to ensure close contact with the side groove 521 of the inner cylinder 52, thereby fixing the relative position of the inner cylinder 52 and the outer cylinder 51 and ensuring the stable length of the telescopic rod 5.

[0036] Furthermore, the elastic retractable rod 6 includes a sleeve 61 with an open lower end and a movable rod 62. The sleeve 61 is fixedly connected to the lower end of the inner tube 52, and the movable rod 62 is slidably connected to the inner lower end of the sleeve 61. The upper surface of the movable rod 62 is fixedly connected to a spring 63, and the upper end of the spring 63 is fixedly connected to the inner top side of the sleeve 61.

[0037] Specifically, when the AGV 3 reaches the machine platform, the metal universal ball wheel 9 contacts the T-shaped metal sheet 2. Because the T-shaped metal sheet 2 has a certain thickness, the metal universal ball wheel 9 applies additional compressive force to the spring 63 to maintain contact with the T-shaped metal sheet 2. The elasticity of the spring 63 allows the movable rod 62 to slide up and down within the sleeve 61, thereby adapting to the thickness variations of the T-shaped metal sheet 2 and ensuring that the metal universal ball wheel 9 maintains close contact with the T-shaped metal sheet 2, thereby maintaining effective static electricity conduction.

[0038] Furthermore, upper bolt columns 41 are fixedly connected on both sides of the lower surface of the mounting disc 4, and upper nuts 42 are provided on the outer threaded sleeves of the upper bolt columns 41. Lower bolt columns 71 are fixedly connected on both sides of the upper surface of the fixing disc 7, and lower nuts 72 are provided on the outer threaded sleeves of the lower bolt columns 71. The lower end of the conductive wire 8 is fixedly connected to a lower wire nose 81, and the upper end of the conductive wire 8 is fixedly connected to an upper wire nose 82. The lower wire nose 81 is movably sleeved on the outer side of the lower bolt column 71 and fixed by the lower nut 72. The upper wire nose 82 is movably sleeved on the outer side of the upper bolt column 41 and fixed by the upper nut 42.

[0039] Specifically, the conductive wire 8 is detachably connected to the mounting disc 4 and the fixed disc 7 to facilitate subsequent maintenance and replacement. Preferably, the conductive wire 8 can be made of copper stranded wire or aluminum stranded wire, which has excellent conductivity and flexibility, helping to ensure the stable performance of the conductive wire 8.

[0040] The above is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
