[0002] The photovoltaic industry is experiencing rapid growth. The production of photovoltaic components faces harsh working environments, including acidic, alkaline, high-temperature steam tanks, and humidity. The loading baskets for photovoltaic panels require handling equipment to move the panels. This has several drawbacks: First, the linear motion pairs of current handling equipment utilize metal rails, which are susceptible to rust and corrosion in corrosive environments, generating contamination from metal ions. Second, to reduce friction, a metallic oil film is applied to the rail surface, which also generates contamination. Consequently, current handling equipment is difficult to use in applications requiring high cleanliness and free of metal ion contamination. Utility Model Content

[0030] The present invention will be described in further detail below with reference to the accompanying drawings. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0031] Figures 1 to 4 A schematic diagram shows a transporter with a corrosion-resistant, high-cleanliness sliding pair according to an embodiment of the present invention. As shown in the figure, the transporter with a corrosion-resistant, high-cleanliness sliding pair includes: a sliding pair 1, a longitudinal moving frame 2, a lifting unit 3, a lifting frame 4, and a loading basket 5;

[0032] The sliding pair 1 comprises a plastic rail 11 and a slider 12 that slide in concert with each other. The rail 11 is made of a low-friction, self-lubricating polymer material, preferably PP, PVDF, PE, POM, PEEK, or ECTEF. The outer contact surface of the rail 11 has a strip-shaped groove that aligns with the slider 12, enabling efficient guided transmission. The slider 12 is preferably a metal or polymer plastic slider.

[0033] The longitudinal moving frame 2 is vertically arranged and has at least one slider 12 fixedly connected to its side. A longitudinal plastic slide rail 11 is installed on the slider 12. The plastic slide rail 11 is fixed to the side surface of the inner frame 02. The longitudinal moving frame 2 can move horizontally along the plastic slide rail 11.

[0034] The driving part 30 of the lifting part 3 is connected to the longitudinal moving frame 2 and its output end 31 is fixedly connected to the vertical lifting frame 4. The lifting part 3 drives the lifting frame 4 to move vertically.

[0035] The upper end of the lifting frame 4 is vertically connected to the horizontal frame 6, and the lower end of the horizontal frame 6 is equipped with a clamping claw 7. At least one trough 01 is set in the frame 02. The clamping claw 7 can take and place the loading basket 5 into the trough 01. The loading basket 5 contains the sheet, and the trough 01 is any processing trough in the photovoltaic product processing production line, preferably a drying trough or a cleaning trough.

[0036] The beneficial effects of the transport machine with a corrosion-resistant and high-cleanliness sliding pair are as follows: first, the new sliding pair 1 has a plastic slide rail 11, which is corrosion-resistant and rust-proof in harsh working environments such as acid, alkali, and around high-temperature steam tanks and in humidity, and is free of metal ion pollution; second, the plastic slide rail 11 has high smoothness and does not require a metal oil film to reduce the friction coefficient, thus solving the problem of metal oil film pollution; third, the plastic slide rail 11 is made of polymer material and has self-lubricating properties. It not only has a good low friction coefficient, but also has no metal oil film pollution; fourth, the device is suitable for a variety of harsh applications and meets the production of photovoltaic products.

[0037] Preferably, the blank of the plastic slide rail 11 is machined with a universal milling cutter on a gantry milling machine to form a groove, thereby forming an intermediate product. A thickness margin is reserved at the bottom of the intermediate product to ensure vacuum pressure. The final outer dimensions are then machined with a forming milling cutter, which is adapted to the outer dimensions of the plastic slide rail 11. This advantageously results in improved machining accuracy and consistent dimensions during the secondary machining process, and in improved linear guidance of the sliding pair 1.

[0038] Preferably, the plastic slide rail 11 is made of a composite of a polymer material and a solid lubricant with a low friction coefficient, and the solid lubricant is preferably polytetrafluoroethylene or graphite. The outer wall contact surface of the plastic slide rail 11 has tiny grooves, and the solid lubricant is automatically pressed into the grooves, thereby achieving self-lubrication and friction reduction of the plastic slide rail 11; the slider 12 is a metal slider or a plastic slider made of a polymer material, and the balls in the metal slider press against the plastic slide rail 11 to allow the solid lubricant to enter the strip-shaped grooves. The beneficial effect is that the plastic slide rail 11 is made of a composite of a polymer material and a solid lubricant. During movement, the solid lubricant will enter the strip-shaped grooves, thereby forming a self-lubricating structure, which not only has a good low friction coefficient, but also is free of metal oil film pollution.

[0039] Furthermore, two support seats 21 are respectively provided at the upper and lower ends of a vertical side surface of the longitudinal moving frame 2. The upper plate of each support seat 21 is threadedly connected to a slider 12. The two sliders 12 at the upper end slide in conjunction with the upper plastic slide rail 11 and the two sliders 12 at the lower end slide in conjunction with the lower plastic slide rail 11.

[0040] Two plastic slide rails 11 are connected below the two mounting beams 020 on the side surface of the frame 02. Its beneficial effect is that the upper and lower slide rails and two sliders are provided on each slide rail, so that the transporter has more accurate horizontal movement accuracy.

[0041] Preferably, the mounting beam 020 is made of angle steel or aluminum profile; the support seat 21 is a right-angle seat with a reinforcing rib plate. The beneficial effect is that the mounting structure is simple, easy to assemble, and has good mechanical properties.

[0042] Furthermore, the output end 31 includes a screw 311 and a nut 312. The lower end of the screw 311 is vertically connected to the longitudinal frame 2 through a seated bearing 313, and the extended end sleeve driving unit 30. The upper end sleeve of the screw 311 engages the nut 312, which is fixed to the lower end of the lifting frame 4. The beneficial effect is that the lifting unit 3 of this configuration can achieve high-precision lifting motion.

[0043] Preferably, the driving part 30 is any one of a direct-connected servo motor 301, a synchronous belt transmission system 302 and a gear transmission system; the beneficial effect is that the driving part 30 of this arrangement has stable power and precise movement position.

[0044] Preferably, the lifting part 3 further includes a vertical guide part 32, which includes a vertical slide rail and a vertical slider made of a self-lubricating polymer plastic material. The beneficial effect is that this arrangement ensures the accuracy of lifting and while avoiding metal ion and metal oil film contamination.

[0045] Furthermore, the transporter is used for material transfer operations in the wet process of photovoltaic product processing, and the transporter transports the loading frame 5 into the tank body 01.

[0046] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
