Description

Technical Field

[0001] This utility model belongs to the field of chemical vapor deposition technology, specifically relating to a BP regeneration protective frame. Background Technology

[0002] Backplates (BPs) are core components in equipment used in processes such as chemical vapor deposition (CVD). After prolonged use, backplates require professional cleaning, repair, and performance restoration—a process known as regeneration. Regenerated backplates must undergo rigorous inspection to ensure their surface quality, dimensions, and performance indicators meet standards before being repackaged and used on the production line. Traditionally, this post-regeneration inspection process involves using flexible slings to suspend the regenerated backplate in the air, allowing operators to inspect it thoroughly and perform subsequent packaging operations without any blind spots.

[0003] However, this reliance on sling suspension carries risks. Slings are prone to wear and aging with repeated use, and their strength reduction is difficult to assess visually. During inspection, if a sling breaks due to insufficient strength, the recycled backsheet will fall from a height, rendering it unusable and resulting in significant economic losses. Furthermore, in the sling-suspended inspection environment, any slight disturbance or minor touch during operation can cause the suspended backsheet to shake or rotate, interfering with the inspector's accurate identification and assessment of minute scratches, contaminants, or repair defects on the backsheet surface, directly impacting the quality assessment of the finished product. Additionally, suspended backsheets pose safety risks such as collisions and impact damage.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: In order to overcome the above shortcomings, this utility model provides a BP regenerative protective frame, which forms a stable support for the back plate through a telescopic bracket, thus solving the safety hazards and inconvenience of operation in the traditional sling suspension mode.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a BP recycling protective frame, including a first support and a second support. The first support has a first protective position for supporting one side of the back plate, and the second support has a second protective position for supporting the other side of the back plate. A telescopic tube is provided between the first support and the second support. Both ends of the telescopic tube extend into the interior of the first and second supports, respectively, and slide in cooperation with the first and second supports, allowing the first and second supports to move towards or away from each other. The first and second supports are each provided with a locking mechanism for locking the relative positions of the first and second supports and the telescopic tube. A set of rollers is connected to the bottom of each of the first and second supports.

[0007] In this invention, the telescopic tube's two ends slide in engagement with the first and second supports, respectively. Adjustment allows the first and second supports to move towards or away from each other, accommodating back panels of different sizes. During installation, the operator smoothly places the back panel's two edges into the first and second protective positions, ensuring the back panel is supported by rigid supports and in a stable state. This facilitates inspection of the back panel and eliminates the risk of product damage and personal injury due to broken or swaying slings. A locking mechanism locks the relative positions of the first and second supports and the telescopic tube after adjustment, preventing accidental retraction during inspection or movement. A set of rollers is connected to the bottom of each of the first and second supports, allowing easy adjustment of the distance between them and the position of the protective frame, greatly improving operational flexibility and efficiency.

[0008] Furthermore, in the aforementioned BP regenerative protective frame, the first support includes a first base frame, which is a square frame formed by welding square tubes. The second support includes a second base frame, which is a square frame formed by welding square tubes. The first and second base frames have openings on opposite sides for telescopic tubes to pass through. Both ends of the telescopic tubes extend into the openings in the first and second base frames, respectively, and are slidably connected to the square tubes on both sides of the first and second base frames. The first and second base frames are formed by welding square tubes, resulting in high structural strength and stability, capable of bearing the weight of the backplate without deformation. Simultaneously, the slidable connection of the telescopic tubes inside the first and second base frames ensures that the two base frames are always aligned, preventing misalignment or jamming.

[0009] Furthermore, in the aforementioned BP regenerative protective frame, a first limiting plate is connected to the top surface of the first base frame. The top surface of the first limiting plate has a first limiting groove arranged along the extension direction of the telescopic tube, which supports and limits one side of the back plate. A second limiting plate is connected to the top surface of the second base frame. The top surface of the second limiting plate has a second limiting groove arranged along the extension direction of the telescopic tube, which supports and limits the other side of the back plate. The first and second limiting grooves extend along the direction of the telescopic tube, providing continuous support for the bottom of the back plate and restricting the back plate from moving back and forth on the horizontal plane, thus achieving precise positioning.

[0010] Furthermore, in the aforementioned BP regenerative protective frame, a first locking plate is connected to the end of the first limiting plate away from the second limiting plate. The first locking plate has a first locking groove on the side near the first limiting plate, and the first locking groove and the first limiting groove constitute a first protective position. A second locking plate is connected to the end of the second limiting plate away from the first limiting plate. The second locking plate has a second locking groove on the side near the second limiting plate, and the second locking groove and the second limiting groove constitute a second protective position. The first locking groove and the second locking groove cooperate with the limiting groove to block the back panel from the side, effectively preventing the back panel from tilting forward or backward due to accidental collision or instability of its own center of gravity, thus achieving reliable fall protection.

[0011] Furthermore, in the aforementioned BP regeneration protective frame, the widths of the first locking groove, the first limiting groove, the second locking groove, and the second limiting groove are appropriately matched to the thickness of the back plate. This arrangement prevents excessive swaying of the back plate within the grooves, ensuring positioning accuracy and preventing damage to the back plate caused by impacts during movement and inspection due to excessive gaps.

[0012] Furthermore, in the aforementioned BP regenerative protective frame, the first locking groove, the first limiting groove, the second locking groove, and the second limiting groove are all coated with adhesive. This adhesive coating provides cushioning and scratch protection to the backplate, while also minimizing the gap between the backplate and the locking and limiting grooves, thus improving positioning accuracy and protection.

[0013] Furthermore, in the aforementioned BP regenerative protective frame, the first and second locking plates are vertically arranged. The vertically arranged locking plates provide a vertical reference plane, enabling stable support for common rectangular backplates and also allowing for adaptation to other backplate shapes, thus exhibiting good versatility.

[0014] Furthermore, in the aforementioned BP regenerative protective frame, a first support rod connects the first locking plate and the first base frame. A second support rod connects the second locking plate and the second base frame. The first and second support rods, together with the locking plate and the base frame, form a triangular support structure, improving the structural stability of the protective frame. The first and second support rods help the locking plate resist the overturning force generated by the back plate.

[0015] Furthermore, in the aforementioned BP regenerative protective frame, the first support rod includes a pair of first support rods and a pair of second support rods. One end of the pair of first support rods is connected to the vicinity of the top of the first locking plate, and the other end of the pair of first support rods is connected to two diagonal positions on the side of the first base frame away from the second base frame, respectively. One end of the pair of second support rods is connected to the vicinity of the middle of the first locking plate, and the other end of the pair of second support rods is connected to the middle of the square tubes on both sides of the first base frame, respectively. The structure of the second support rod is symmetrically arranged with the first support rods relative to the longitudinal centerline of the telescopic tube. The first support rod connects the top of the locking plate and the far corner of the base frame, forming a large triangle to resist the overturning force of the back plate towards both ends of the protective frame. The second support rod connects the middle of the locking plate and the sides of the base frame, forming an auxiliary stabilizing structure to resist the overturning force of the back plate in front and behind, enhancing the rigidity and anti-swaying and anti-overturning capabilities of the entire protective frame, ensuring the stability and safety required for back plate inspection.

[0016] Furthermore, in the aforementioned BP regeneration protective frame, the first and second base frames have threaded holes near the openings into which the telescopic tube extends. The locking mechanism is a hand-tightening bolt, threaded into the threaded hole. Operators can lock the device by hand-tightening the locking mechanism, using the bolt end to press against the telescopic tube, simplifying the operation and improving the efficiency of adjustment and locking.

[0017] As can be seen from the above technical solution, this utility model has the following beneficial effects: The BP recyclable protective frame of this utility model, through the first and second supports forming a stable support for the back panel, solves the safety hazards and operational inconvenience problems existing in the traditional sling suspension mode. The first and second supports achieve spacing adjustment through telescopic tubes, which can flexibly adapt to back panels of different specifications. Combined with the hand-tightening bolt locking mechanism, the size of the protective frame can be quickly fixed, ensuring structural stability during operation. The L-shaped design and rubber coating of the protective position ensure accurate positioning of the back panel and avoid contact damage. Attached Figure Description

The top surface of the second limiting plate 221 is provided with a second limiting groove 2211 arranged along the extension direction of the telescopic tube 3. The second limiting groove 2211 is used to support and limit the other side of the back plate.

[0023] In this embodiment, a first locking plate 122 is connected to the end of the first limiting plate 121 away from the second limiting plate 221. The first locking plate 122 has a first locking groove 1221 near the first limiting plate 121. The first locking groove 1221 and the first limiting groove 1211 constitute a first protective position 11. A second locking plate 222 is connected to the end of the second limiting plate 221 away from the first limiting plate 121. The second locking plate 222 has a second locking groove 2221 near the second limiting plate 221. The second locking groove 2221 and the second limiting groove 2211 constitute a second protective position 21. The first locking groove 1221 and the second locking groove 2221 cooperate with the limiting groove to block the back plate from the side and prevent tipping.

[0024] In this embodiment, the width of the first locking groove 1221, the first limiting groove 1211, the second locking groove 2221, and the second limiting groove 2211 are adapted to the thickness of the back plate.

[0025] In this embodiment, the first locking groove 1221, the first limiting groove 1211, the second locking groove 2221, and the second limiting groove 2211 are respectively coated with adhesive. The adhesive coating provides cushioning and scratch protection for the back panel.

[0026] In this embodiment, the first locking plate 122 and the second locking plate 222 are arranged vertically.

[0027] In this embodiment, a first support rod 13 is connected between the first locking plate 122 and the first base frame 12. A second support rod 14 is connected between the second locking plate 222 and the second base frame 22.

[0028] In this embodiment, the first support rod 13 includes a pair of first support rods 131 and a pair of second support rods 132. One end of the pair of first support rods 131 is connected to the vicinity of the top of the first locking plate 122, and the other end of the pair of first support rods 131 is respectively connected to two diagonal positions on the side of the first base frame 12 away from the second base frame 22. One end of the pair of second support rods 132 is connected to the vicinity of the middle of the first locking plate 122, and the other end of the pair of second support rods 132 is respectively connected to the middle of the square tubes on both sides of the first base frame 12. The structure of the second support rod 14 is symmetrically arranged with respect to the longitudinal centerline of the telescopic tube 3 as the first support rod 13 is.

[0029] In this embodiment, the first base frame 12 and the second base frame 22 are provided with threaded holes 15 near the openings into which the telescopic tube 3 extends. The locking mechanism is a hand-tightening bolt, and the locking mechanism is threaded into the threaded hole 15.

[0030] This utility model is used for back panel inspection. During inspection, the protective frame is pushed to the inspection area by the rollers 4 at the bottom of the first base frame 12 and the second base frame 22. The hand-tightening bolts on both sides are loosened counterclockwise. According to the known width of the back panel to be inspected, the first bracket 1 and the second bracket 2 are pushed so that the distance between the first protective position 11 and the second protective position 21 is slightly larger than the width of the back panel, and then the hand-tightening bolts are pre-tightened clockwise. The back panel is horizontally hoisted to directly above the protective frame by operating a crane or other lifting equipment. Then the back panel is smoothly lowered so that its two sides fall into the first limiting groove 1211 and the second limiting groove 2211 simultaneously and in one go, and the sides of the back panel are engaged with the rubber coating of the first locking groove 1221 and the second locking groove 2221. Observe whether the back panel is fully engaged. If necessary, loosen the hand-tightening bolts and fine-tune the first bracket 1 and the second bracket 2 to ensure that the bottom and sides of the back panel are engaged in the limiting grooves and locking grooves respectively. After adjustment, tighten the hand-tightening bolts clockwise to lock the relative position of the telescopic tube 3 with the first base frame 12 and the second base frame 22 to prevent gap changes. The operator gently pushes the sides of the back panel to check for any shaking and confirms that the hand-tightening bolts are locked and the connection between the first support rod 13 and the second support rod 14 is secure. The operator stands on both sides of the protective frame to inspect the back panel. After the inspection is completed, loosen the hand-tightening bolts counterclockwise and use a crane to lift the back panel vertically upwards to disengage it from all limiting grooves and locking grooves.
