Description

Technical Field

[0001] This utility model relates to the field of ceramic wheel brush technology, and in particular to an auxiliary device for installing ceramic wheel brushes. Background Technology

[0002] Ceramic wheel brushes are key grinding tools in printed circuit board (PCB) manufacturing. Their cylindrical brush bodies are densely covered with high-hardness ceramic abrasive, and through high-speed rotation, they precisely grind the PCB surface, effectively removing copper burrs, oxide layers, and substrate unevenness, ensuring smooth circuitry and impedance stability. Due to the wear resistance and consistency of their material, ceramic wheel brushes are particularly suitable for surface treatment of high-end PCBs and have become an important grinding equipment in high-precision PCB processing. However, as grinding equipment, ceramic wheel brushes frequently require replacement. Because of their considerable weight, operators must manually lift the heavy cylinder to complete disassembly, alignment, and installation. This process is not only physically demanding and prolongs downtime, but also prone to brush falls due to operator fatigue or loss of grip, potentially injuring operators' feet or damaging equipment components. Therefore, improving the ease of disassembly and installation of ceramic wheel brushes while reducing safety risks has become a crucial technical challenge in the field of ceramic wheel brush technology. Utility Model Content

[0003] In view of the above-mentioned prior art, the present invention provides a ceramic wheel brush installation auxiliary device, which mainly solves the technical problem of how to improve the convenience of ceramic wheel brush disassembly and installation and reduce safety risks.

[0004] To achieve the above objectives, the technical solution of this utility model embodiment is implemented as follows:

[0005] A ceramic brush mounting auxiliary device includes a bracket and casters. The casters are located at the bottom of the bracket, which has a U-shaped placement groove. An extension frame is provided on one side of the U-shaped placement groove, and the bottom of the extension frame is hinged to the lower part of the U-shaped placement groove. A limiting mechanism is fixedly connected to the bottom of the extension frame, which can limit the rotation angle of the extension frame. Several blocking mechanisms are provided in the middle of the U-shaped placement groove. Each blocking mechanism includes a pull plate, a first stop, a second stop, and a gear. One side of the pull plate is fixedly connected to the first stop. Racks are fixedly connected to the pull plate and the side of the second stop near the gear. The pull plate is driven by the rack and the gear to the second stop. Slots are provided on both sides of the U-shaped placement groove.

[0006] Preferably, the upper end of the extension frame is configured as an arc structure.

[0007] Preferably, the upper end of the arc structure is provided with a hook, the hook is hinged to the arc structure, and the upper end of the U-shaped placement groove is provided with a round rod that cooperates with the hook.

[0008] Preferably, the bracket is provided with a plurality of vertically arranged through holes, and the U-shaped placement groove is detachably connected to the bracket by bolts and through holes.

[0009] Preferably, the limiting mechanism includes a plurality of limiting blocks, which are fixedly connected to the bottom of the extension frame.

[0010] Preferably, the surfaces of the U-shaped placement slot and the extension frame are covered with a buffer layer, and the outer surfaces of the first stop and the second stop are also covered with a buffer layer.

[0011] Preferably, a pull handle is provided on one side of the pull plate.

[0012] Preferably, a slide rail is provided at the lower end of the slot, and the bottom of both the first stop and the second stop are fixedly connected to sliders that cooperate with the slide rail.

[0013] The beneficial effects of this utility model are as follows: This application can place several ceramic brush wheels flat in a U-shaped placement groove and transport the brush wheels using the casters at the bottom of the bracket. The bottom of the extension frame can rotate and unfold relative to the U-shaped placement groove, allowing the cylindrical ceramic brush wheels to roll from above the U-shaped placement groove to above the extension frame. The extension frame can extend to the ceramic brush wheel installation position without manual support, making the installation of the ceramic brush wheels more convenient.

[0014] Meanwhile, this application also includes a blocking mechanism. The first block can move synchronously with the movement of the pull plate, and the second block can move in the opposite direction of the pull plate with the cooperation of the rack and gear. This allows the first and second blocks to approach each other and pass through the slot, blocking the wheel brushes that are laid flat on both sides, thus preventing damage to the wheel brushes or increased burden on the operators during transportation and operation due to rolling collisions.

[0015] In summary, this application, by setting up an extension bracket and a blocking mechanism, can improve the convenience of disassembling and installing ceramic wheel brushes and reduce safety risks. Attached Figure Description

[0025] Example

[0026] See attached document Figure 1-5This application provides a ceramic wheel brush installation auxiliary device, including a bracket 1 and a universal wheel 2. The universal wheel 2 is disposed at the bottom of the bracket 1. The bracket 1 is provided with a U-shaped placement groove 3. An extension frame 4 is provided on one side of the U-shaped placement groove 3. The bottom of the extension frame 4 is hinged to the lower part of the U-shaped placement groove 3. A limiting mechanism (not shown) is fixedly connected to the bottom of the extension frame 4. The limiting mechanism (not shown) can limit the rotation angle of the extension frame 4. A plurality of blocking mechanisms 7 are provided in the middle of the U-shaped placement groove 3. The blocking mechanism 7 includes a pull plate 8, a first stop block 9, a second stop block 10 and a gear 11. One side of the pull plate 8 is fixedly connected to the first stop block 9. A rack 12 is fixedly connected to both the pull plate 8 and the second stop block 10 on the side near the gear 11. The pull plate 8 is connected to the second stop block 10 through the rack 12 and the gear 11. Slots 13 are provided on both sides of the U-shaped placement groove 3. This device can place several ceramic brush wheels flat in a U-shaped placement slot 3 and transport them using the casters 2 at the bottom of the bracket 1. The bottom of the extension frame 4 can rotate and unfold relative to the U-shaped placement slot 3, allowing the cylindrical ceramic brush wheels to roll from above the U-shaped placement slot 3 to above the extension frame 4. The extension frame 4 can extend to the ceramic brush wheel installation position without manual support. It can also roll disassembled ceramic brush wheels along the extension frame 4, making the installation and removal of the ceramic brush wheels more convenient. Simultaneously, this device is equipped with a blocking mechanism 7. The first stop block 9 can move synchronously with the movement of the pull plate 8, and the second stop block 10 can move in the opposite direction of the pull plate 8 under the cooperation of the rack 12 and gear 11. This causes the first stop block 9 and the second stop block 10 to approach each other and pass through the slot 13, blocking the brush wheels placed flat on both sides, preventing damage to the brush wheels or increasing the burden on the operator during transportation and operation due to rolling collisions. In this embodiment, the end of the U-shaped placement groove 3 furthest from the extension frame 4 is configured with a detachable baffle 14. Operators can easily load the brush wheel by removing and installing the baffle 14. In this embodiment, the baffle 14 is hinged to the U-shaped placement groove 3 at its bottom and detachably connected to the top by bolts. Alternatively, the baffle 14 and the U-shaped placement groove 3 can also employ other detachable connection methods commonly used in the art. In summary, this device, by incorporating the extension frame 4 and the blocking mechanism 7, improves the ease of disassembling and installing the ceramic brush wheel and reduces safety risks.

[0027] Specifically, the upper end of the extension frame 4 is configured as an arc structure 15, which can fit the bottom of the wheel brush, so that the wheel brush can stay at one end of the extension frame 4, making it convenient for operators to install.

[0028] Specifically, a hook 16 is provided at the upper end of the arc structure 15, and the hook 16 is hinged to the arc structure 15. A round rod 17 that cooperates with the hook 16 is provided at the upper end of the U-shaped placement groove 3. The hook 16 and the round rod 17 can control the opening and closing of the extension frame 4. When the ceramic brush needs to be transported, the hook 16 is connected to the round rod 17, so that one end of the U-shaped placement groove 3 is blocked by the closed extension frame 4, preventing the ceramic brush wheel from rolling out.

[0029] Specifically, the bracket 1 is provided with several vertically arranged through holes 18, and the U-shaped placement groove 3 is detachably connected to the bracket 1 via bolts and through holes 18. The bolts and through holes 18 can control the height of the U-shaped placement groove 3, thereby controlling the height of the extension frame 4 when it is unfolded, so as to match the height of related devices, making it easier for operators to install and remove the wheel brush.

[0030] Specifically, the limiting mechanism (not shown) includes several limiting blocks 6, which are fixedly connected to the bottom of the extension frame 4. By setting the limiting blocks 6, this device ensures that when the extension frame 4 is unfolded into a horizontal state, the limiting blocks 6 can contact the bottom of the U-shaped placement groove 3 and limit the extension frame 4.

[0031] Specifically, the surfaces of the U-shaped placement groove 3 and the extension frame 4 are covered with a buffer layer, and the outer surfaces of the first stop 9 and the second stop 10 are also covered with a buffer layer. In this embodiment, the buffer layer is made of sponge, which can be covered by common methods such as bundling and adhesion. It should be understood that the buffer layer can also be made of common materials with cushioning effects such as cotton cloth and rubber layers. The buffer layer can reduce damage caused by bumps to the device.

[0032] Specifically, a pull handle 19 is provided on one side of the pull plate 8. By providing the pull handle 19, this device makes it more convenient for operators to pull the pull plate 8.

[0033] Specifically, a slide rail 20 is provided at the lower end of the slot 13. The bottoms of both the first stop 9 and the second stop 10 are fixedly connected to sliders 21 that cooperate with the slide rail 20. Both ends of the gear 11 are rotatably connected to the slot 13. By providing the slide rail 20, this device can more reliably control the sliding of the first stop 9 and the second stop 10. A limiting U-shaped frame 22 is provided at the lower end of the pull plate 8. The limiting U-shaped frame 22 is fixedly connected to the bottom of the U-shaped placement groove 3 near the second stop 10, allowing the pull plate 8 to maintain horizontal movement.

[0034] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. The protection scope of this utility model should be determined by the protection scope of the stated claims.
