Description

Technical Field

[0001] This utility model relates to the field of static electricity conduction technology in industrial automation workshops, and in particular to an anti-static track structure for AGV vehicles. Background Technology

[0002] With continuous technological advancements, the traditional industrial plant model relying on manual handling tools such as forklifts and pallet jacks can no longer meet the high-efficiency and intelligent requirements of modern automated production workshops. The emergence of AGV intelligent material handling robots has successfully solved the problem of automated material and product flow, significantly reducing labor costs and greatly improving the overall efficiency of automated production lines. In automobile manufacturing, especially in the production workshops of new energy vehicle companies, large AGVs are used for the precision transfer of complete vehicles. In such working environments, the accumulation of static charge generated by the equipment is a problem that cannot be ignored. To ensure safety and protect the robot's precision electronic control system, the static charge on the AGV body must be promptly and reliably conducted to the ground. Therefore, it is necessary to lay dedicated static-dissipating tracks on the ground and reliably connect them to the workshop's grounding system.

[0003] Initially, copper foil was commonly used as a conductive track. While simple and inexpensive, this method suffered from extremely poor durability. Under the continuous crushing force of large AGVs, the copper foil would wear down rapidly, peel, or even break, leading to a sharp decline in conductivity or even complete failure. Once the copper foil wore down, the conductive copper brushes at the bottom of the AGV robot could no longer make proper contact, preventing the effective release of static charge and posing a potential threat of damage to the robot's sensitive electronic components. This safety hazard was particularly prominent in areas with stringent requirements, such as electronics, semiconductors, chemicals, and explosion-proof applications. To address the insufficient durability of copper foil, the industry began using copper busbars (copper strips) with superior conductivity and mechanical strength to replace it. Copper busbars, with their high current carrying capacity and low resistivity, became an ideal conductor material for conductive tracks. However, copper busbars are relatively soft and, after prolonged exposure to the repeated crushing and squeezing of heavy AGV wheels and vibrations from equipment operation, are prone to plastic deformation, localized warping, or even complete buckling.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The purpose of this invention is to overcome the limitations of existing technologies that commonly use copper foil as a conductive track. While this method is simple to implement and low in cost, its durability is extremely poor. Under the continuous crushing of large AGVs, the copper foil will wear down rapidly, peel, or even break, leading to a sharp decline in its conductivity or even complete failure. Once the copper foil is worn, the conductive copper brushes at the bottom of the AGV robot will be unable to make good contact with it, preventing the effective release of static charge and posing a potential threat of damage to the robot's sensitive electronic components. In areas with stringent requirements such as electronics, semiconductors, chemicals, and explosion-proof applications, the safety hazards posed by this problem are particularly prominent. To address the insufficient durability of copper foil, the industry has begun to use copper busbars (copper strips) with superior conductivity and higher mechanical strength to replace copper foil. Copper busbars, due to their high current carrying capacity and low resistivity, have become an ideal conductor material for anti-static tracks. However, copper busbars are relatively soft and are prone to plastic deformation, local warping, or even overall lifting after being subjected to repeated rolling, squeezing, and vibration from heavy AGV wheels and equipment operation. This paper proposes an anti-static track structure for AGVs that utilizes the lateral pressure generated when non-shrink grout is pumped into a strip groove. This pressure forces the elastic locking mechanism to deform, driving the locking block to firmly engage in a pre-set slot. This process creates a permanent, three-dimensional mechanical lock, securing the copper busbar. The bottom is anchored to the ground foundation as a whole. Compared with traditional pressure blocks, this structure can resist vertical lifting forces from the source. Compared with the traditional bolt fixing, it is more convenient. It can directly lock and fix by using the lateral pressure generated when pumping in non-shrink grout, which improves construction efficiency and reduces construction difficulty. The cross-section of the strip groove is designed as an inverted isosceles trapezoidal structure. That is, the groove wall, which is narrow at the top and wide at the bottom, can effectively prevent the cured non-shrink grout and the wrapped copper busbar components from moving upward. This further strengthens the ability of the entire track system to resist repeated rolling and impact loads from heavy AGVs.

[0006] To achieve the above objectives, this utility model provides an anti-static track structure for AGV vehicles, comprising:

[0007] Two parallel strip-shaped grooves are formed along the length of the AGV vehicle's moving track, and slots are respectively provided on the inner walls of the two sides of the strip-shaped grooves;

[0008] The copper busbar is fixed in the strip groove by casting with non-shrink grout. The copper busbar has an inverted concave structure, and the bottom of its two vertical ends is respectively engaged with a detachable elastic locking mechanism.

[0009] The elastic locking mechanism includes a deformation plate and a locking block integrally formed with the outer wall of the deformation plate;

[0010] When non-shrink grout is pumped into the strip groove between the two elastic locking mechanisms, the non-shrink grout squeezes the elastic locking mechanism to deform, causing the locking block to be engaged in the groove, thereby achieving the positioning of the copper busbar.

[0011] In one embodiment of this utility model, the ends of the copper busbars on both sides are electrically connected to the grounding point of the workshop steel column through hot-dip galvanized flat iron to form a continuous grounding protection circuit, which is used to safely discharge the static electricity on the copper busbars to the ground.

[0012] In one embodiment of this utility model, the cross-section of the strip groove is an inverted isosceles trapezoidal structure.

[0013] In one embodiment of this utility model, a wedge-shaped groove is provided at the bottom of the two vertical ends of the copper busbar, and a wedge-shaped block is integrally formed on the upper part of the deformation plate to cooperate with the wedge-shaped groove. During installation, the wedge-shaped block is inserted into the wedge-shaped groove along the length direction to complete the assembly of the copper busbar and the deformation plate.

[0014] In one embodiment of this utility model, the connection between two adjacent copper busbars is connected by a long copper busbar pad, and the long copper busbar pad is set below the two adjacent copper busbars. The gap between the copper busbar and the long copper busbar pad is welded by soldering, and the solder joint is ground flat to ensure the electrical continuity between adjacent copper busbars.

[0015] In one embodiment of this utility model, the dimensions of the copper busbar are 80mm*5mm*2000mm.

[0016] Compared with the prior art, the anti-static track structure of the AGV vehicle according to this utility model utilizes the lateral pressure generated when non-shrink grout is pumped into the strip groove to force the elastic locking mechanism to deform, driving the locking block to firmly engage in the preset slot. This process forms a permanent, three-dimensional mechanical lock, anchoring the bottom of the copper busbar to the ground foundation as a whole. Compared with the traditional pressure block, this structure can resist vertical lifting force from the root. Compared with the traditional bolt fixing, it is more convenient and realizes the locking and fixing directly by utilizing the lateral pressure generated when pumping non-shrink grout, improving construction efficiency and reducing construction difficulty.

[0017] Furthermore, the cross-section of the strip groove is designed as an inverted isosceles trapezoidal structure, that is, the groove wall, which is narrow at the top and wide at the bottom, can effectively prevent the cured non-shrink grout and the encased copper busbar components from moving upward. This further enhances the ability of the entire track system to resist repeated crushing and impact loads from heavy AGVs. Attached Figure Description

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The specific embodiments of this utility model are described in detail below, but it should be understood that the scope of protection of this utility model is not limited to the specific embodiments.

[0025] Unless otherwise expressly stated, throughout the specification and claims, the term "comprising" or its variations such as "including" or "comprises" shall be understood to include the stated elements or components without excluding other elements or other components.

[0026] An anti-static track structure for an AGV vehicle according to a preferred embodiment of the present invention includes:

[0027] Two parallel strip grooves 1 are opened along the length of the AGV vehicle's moving track, and slots 11 are respectively provided on the inner walls of both sides of the strip grooves 1;

[0028] The copper busbar 2 is fixed in the strip groove 1 by pouring non-shrink grout. The copper busbar 2 has an inverted concave structure, and the bottom of its two vertical ends is respectively connected to a detachable elastic locking mechanism 3.

[0029] The elastic locking mechanism 3 includes a deformable piece 31 and a locking block 32 integrally formed with the outer wall of the deformable piece 31;

[0030] When non-shrink grout is pumped into the strip groove 1 between the two elastic locking mechanisms 3, the non-shrink grout squeezes the elastic locking mechanism 3 to deform, causing the locking block 32 to be engaged in the slot 11, thereby achieving the positioning of the copper busbar 2.

[0031] Specifically, the lateral pressure generated when non-shrink grout is pumped into the strip groove 1 forces the elastic locking mechanism 3 to deform, driving the locking block 32 to firmly engage in the preset slot 11. This process forms a permanent, three-dimensional mechanical lock, anchoring the elastic locking mechanism 3 connected to the bottom of the copper busbar 2 to the ground foundation as a whole. Compared with traditional pressure blocks, this structure can resist vertical lifting forces from the source. Compared with traditional bolt fixing, it is more convenient and realizes direct locking and fixing using the lateral pressure generated when pumping non-shrink grout, improving construction efficiency and reducing construction difficulty.

[0032] The ends of the copper busbars 2 on both sides are electrically connected to the grounding point of the workshop steel column through hot-dip galvanized flat iron 23, forming a continuous grounding protection circuit to safely discharge the static electricity on the copper busbars 2 to the ground.

[0033] Specifically, because copper busbar 2 is firmly fixed and there is no risk of it tilting, the conductive copper brush at the bottom of the AGV robot can always maintain stable and good contact with the surface of copper busbar 2. This allows static charge to be continuously and with low impedance conducted away. At the same time, the ends of copper busbar 2 on both sides are reliably connected to the grounding point of the workshop steel column by hot-dip galvanized flat iron 23, forming a complete and low-resistance grounding protection circuit. This can safely and quickly discharge accumulated static charge to the ground, greatly reducing the risk of static electricity damaging the AGV precision control system. It is particularly suitable for static-sensitive areas such as electronics, semiconductors, chemicals, and explosion-proof areas.

[0034] The cross-section of the strip groove 1 has an inverted isosceles trapezoidal structure.

[0035] Specifically, the cross-section of the strip groove 1 is designed as an inverted isosceles trapezoidal structure. This structure has a "self-locking" effect in the mechanics of non-shrink grout, that is, the groove wall, which is narrow at the top and wide at the bottom, can effectively prevent the cured non-shrink grout and the encased copper busbar 2 component from moving upward. This further strengthens the ability of the entire track system to resist repeated crushing and impact loads from heavy AGVs, ensuring long-term structural stability.

[0036] The bottom of the two vertical ends of the copper busbar 2 is provided with a wedge-shaped groove 21. The upper part of the deformation plate 31 is integrally formed with a wedge-shaped block 33 that matches the wedge-shaped groove 21. During installation, the wedge-shaped block 33 is inserted into the wedge-shaped groove 21 along the length direction to complete the assembly of the copper busbar 2 and the deformation plate 31. The connection between two adjacent copper busbars 2 is connected by a long copper busbar pad 22, and the long copper busbar pad 22 is set below the two adjacent copper busbars 2. The gap between the copper busbar 2 and the long copper busbar pad 22 is welded by soldering, and the solder joint is ground flat to ensure the electrical continuity between adjacent copper busbars 2. The dimensions of the copper busbar 2 are 80mm*5mm*2000mm.

[0037] Specifically, the copper busbar 2 and the elastic locking mechanism 3 are assembled through the insertion of wedge blocks 33 and wedge grooves 21, achieving rapid pre-assembly and disassembly. This greatly facilitates positioning and adjustment before construction and also makes it easier to replace damaged parts in extreme situations. Secondly, long copper busbar pads 22 are used and soldered at the connection points of adjacent copper busbars 2. This not only ensures the continuity of electrical connections and avoids a decrease in conductivity due to loose joints or oxidation, but also ensures the flatness of the track top surface by grinding the solder joints, providing a smooth road surface for AGV operation.

These descriptions are not intended to limit the present invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.
