Description

Technical Field

[0001] This utility model relates to the technical field of telescopic fork equipment, specifically to a static-dissipating device for telescopic forks. Background Technology

[0002] With the rapid development of the intelligent logistics and warehousing industry, telescopic forks are increasingly being used in automated handling scenarios. In the production and transportation of high-end goods such as precision electronic components and semiconductor assemblies, electrostatic discharge (ESD) protection has become a critical requirement—these goods are sensitive to static electricity, and even minor ESD can damage component performance or render them unusable, resulting in significant economic losses.

[0003] Current mainstream telescopic forks generally suffer from unreliable electrical connections between the goods and the forks when handling such high-precision goods.

[0004] 1. Insufficient positioning accuracy: The randomness of the goods' position on the forks causes the conductive components to fail to make stable contact with the goods' surface;

[0005] 2. Poor contact reliability: Traditional conductive structures are mostly rigid connections, which are difficult to adapt to cargo height deviations or vibration scenarios, and are prone to contact failure;

[0006] 3. Risk of electrostatic discharge path breakage: The lack of elastic buffer and adaptive adjustment mechanism may lead to interruption of electrostatic conduction due to mechanical collision or positional displacement.

[0007] The aforementioned defects make existing forks unable to meet the stringent requirements of "reliable grounding and no static electricity accumulation" for high-precision goods. There is an urgent need for a new type of static electricity conductive device that can achieve precise positioning and stable conductivity to ensure the safety and reliability of intelligent warehousing systems in highly static-sensitive scenarios.

[0008] In view of this, the purpose of this utility model is to provide a device for dissipating static electricity for telescopic forks.

[0011] The conductive component includes a contact head, a base, a spring, and a guide pin. The base is fixed to the surface of the telescopic fork and arranged adjacent to the pad, with a vertical guide hole inside. The contact head is installed on the top of the base, and the guide pin is vertically arranged in the guide hole. One end of the guide pin abuts against the bottom surface of the contact head, and the other end abuts against the surface of the telescopic fork. The spring is sleeved on the guide pin.

[0012] Furthermore, the number of positioning components and conductive components is at least two sets, symmetrically arranged on both sides of the bearing surface of the telescopic fork.

[0013] Furthermore, the contact head is made of copper or aluminum alloy, and the top surface of the contact head is plated with a conductive coating.

[0014] Furthermore, a strip-shaped mounting hole is provided on the pad, which is connected to the surface of the telescopic fork by bolts. The length direction of the strip-shaped mounting hole is consistent with the telescopic fork extension direction.

[0015] Furthermore, the buffer plate is a polyurethane board.

[0017] Furthermore, a conductive pad is provided between the base and the telescopic fork.

[0026] The technical solution of this utility model will now be clearly and completely described through specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0027] See appendix Figures 1-3 As shown, this application discloses a static-dissipating device for telescopic forks. Through the collaborative design of a positioning component 1 and a conductive component 2, it achieves precise positioning and reliable electrostatic conduction of goods on the telescopic forks. The positioning component 1 ensures that the position of the goods is fixed each time they are placed on the telescopic forks, providing a stable contact reference for the conductive component 2. The positioning component 1 includes a pad 11, a buffer plate 12, and a positioning pin 13. The pad 11 serves as a mounting base, is made of metal, and its bottom surface is fixed to the surface of the telescopic forks by bolts or quick-release clips. A strip-shaped mounting hole is provided on the top surface, allowing adjustment of 5-15cm along the telescopic fork's extension direction to accommodate goods of different sizes. The bottom surface of the buffer plate 12 is fixed to the pad 11 by an adhesive layer, and the positioning pin 13 is vertically fixed at the center of its top surface. Preferably, the buffer plate 12 is a polyurethane board. Polyurethane material combines cushioning elasticity and positioning rigidity, absorbing the impact force when goods are placed and preventing rigid collision damage. The top of the positioning pin 13 is a columnar boss that precisely matches the positioning hole on the bottom of the goods or pallet to achieve mechanical positioning in the horizontal direction.

[0028] The conductive component 2 forms an electrostatic conduction circuit with the fork body through an elastic contact head, quickly conducting static electricity from the surface of the goods to the ground. The conductive component 2 includes a base 21, a contact head 22, a spring 23, and a guide pin 24. The base 21 is fixed to the surface of the telescopic fork and arranged adjacent to the pad 11 of the positioning component 1. It has a vertical guide hole inside, and a stainless steel or conductive rubber gasket is placed between its bottom surface and the telescopic fork. The contact head 22 is made of copper or aluminum alloy, with a hemispherical or conical protrusion at the top, and a thick silver plating to ensure low-resistance contact with the surface of the goods. The guide pin 24 passes through the guide hole, with one end abutting the bottom surface of the contact head 22 and the other end abutting the surface of the telescopic fork. The spring 23 is a cylindrical helical compression spring, made of stainless steel or coated with PTFE, and is fitted over the guide pin 24 to provide continuous elastic pressure.

[0029] When goods or pallets are placed on the telescopic forks, the locating pin 13 is inserted into its bottom locating hole, and the buffer plate 12 cushions the impact through elastic deformation, ensuring that the goods are fixed in a horizontal position. Since the top of the contact head 22 is higher than the locating pin 24, when the goods fall, the contact head 22 is first compressed to compress the spring 23. The distance between the bottom surface of the contact head 22 and the bottom of the spring mounting cavity of the base 21 is shortened, and the spring 23 generates an elastic reaction force, making the contact head 22 fit tightly against the surface of the goods.

[0030] Preferred options are listed in the appendix. Figure 1 As shown, in this embodiment, the number of positioning components 1 and conductive components 2 are both at least two sets, symmetrically arranged on both sides of the bearing surface of the telescopic fork.

[0031] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
