Description

Technical Field

[0001] This utility model relates to the field of glass polishing, and in particular to a multi-station rotary polishing device for strengthening the edge of glass cover plates. Background Technology

[0002] As a crucial protective component for electronic device screens, the edge reinforcement of glass covers directly impacts the product's impact resistance and aesthetics. Traditional glass edge treatment processes often employ single-station grinding equipment, manually or semi-automatically grinding and reinforcing each glass cover individually. For example, the commonly used single-axis rotary grinder, while simple in structure, suffers from the following significant drawbacks:

[0003] The single-station design means that only one glass cover can be processed at a time, requiring frequent shutdowns to change workpieces, which makes it difficult to meet the needs of large-scale production; the equipment relies on manual adjustment of the grinding disc position, which is prone to uneven edge grinding due to operational errors, and may even result in defects such as chipping and scratches.

[0004] Based on this, we propose a multi-station rotary grinding device for strengthening the edge of glass cover plates. Utility Model Content

[0005] To address the technical problem of low processing efficiency, this utility model provides a multi-station rotary grinding device for strengthening the edges of glass covers.

[0006] This utility model is achieved by the following technical solution: a multi-station rotary grinding equipment for edge strengthening treatment of glass cover plates, including an equipment support, a support base fixedly installed at the top of the equipment support, a grinding mechanism installed on the support base, and an adjustment mechanism installed on the grinding mechanism;

[0007] The grinding mechanism includes a working motor, a first rotating disk, a chain belt, a second rotating disk, a rotating rod, a drive disk, a drive belt, a driven disk, and a grinding disk. The working motor is fixed to the bottom of the support base, and the output shaft of the working motor is connected to the first rotating disk. The first rotating disk is connected to the second rotating disk via a chain belt. The second rotating disk is coaxially connected to a rotating rod, and a mounting plate is sleeved on the surface of the rotating rod. An edge fixing rod and a center fixing rod pass through the mounting plate surfaces. The drive disk is sleeved on the surface of the rotating rod and connected to the driven disk via a drive belt. The driven disk is coaxially connected to the grinding disk.

[0008] The working motor is started, and its output shaft drives the first rotating disk to rotate. The power is transmitted to the second rotating disk through a chain belt, causing the rotating rod to rotate at a constant speed around the axis; this achieves synchronous rotation of multiple stations. The active drive disk on the side wall of the rotating rod drives the driven drive disk to rotate through a drive belt, which in turn drives the grinding disk to rotate at high speed. The grinding surface of the grinding disk contacts the edge of the glass cover plate, and the rotation of the grinding disk creates relative motion, completing the uniform grinding and strengthening of the edge of the glass cover plate.

[0009] The adjustment mechanism includes a fixed base, an adjusting screw, an adjusting seat, a moving block, a moving groove, and a limiting roller. The fixed base is fixed to the surface of the mounting plate. The adjusting screw passes horizontally through the fixed base and is threadedly connected to the adjusting seat. The adjusting seat slides with the moving block through the moving groove, which is located on the surface of the moving block. The limiting roller is installed at the end of the moving block to limit the radial displacement of the grinding disc.

[0010] As a further optimization of this utility model, the adjustment mechanism, by rotating the adjustment screw, pushes the adjustment seat to slide horizontally along the moving groove, thereby driving the moving block and the limiting roller to move synchronously, thus adjusting the radial position of the grinding disc. The rubber layer on the surface of the limiting roller contacts the side wall of the grinding disc, limiting its radial displacement and buffering vibration, ensuring stable grinding pressure.

[0011] As a further optimization of this utility model, the surface of the limiting roller is covered with a rubber layer to buffer the contact pressure.

[0012] As a further optimization of this utility model, the bottom of the equipment support is provided with shock-absorbing feet, and the inside of the shock-absorbing feet is filled with damping material.

[0013] As a further optimization of this utility model, the shock-absorbing feet at the bottom of the equipment support absorb the vibration generated by high-speed rotation through internal damping material, preventing the vibration from being transmitted to the machining interface. This further ensures transmission stability and prevents a decrease in machining accuracy due to vibration.

[0014] As a further optimization of this utility model, the rotating rod and the second rotating disk are coaxially fixedly connected by a keyway.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. This utility model uses a chain to link the first and second rotating disks, driving the rotating rod to rotate multiple mounting disks synchronously, thereby realizing the parallel processing of multiple glass cover plates, significantly improving production efficiency and reducing downtime for material replacement.

[0017] 2. This utility model uses an adjustment mechanism to precisely control the radial position of the grinding disc through the cooperation of the adjusting screw and the moving block. Combined with the rubber buffer layer of the limiting roller, it effectively avoids human operation errors, ensures the uniformity of edge grinding, and reduces defects such as chipping and scratches.

[0018] 3. This utility model absorbs vibration through damping material on the shock-absorbing feet at the bottom of the equipment support, combined with the bearing connection structure between the rotating rod and the support seat, effectively suppressing vibration transmission during high-speed rotation, ensuring the stability of the processing interface, and improving the consistency of edge strengthening effect.

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. Example 1:

[0025] Please combine Figures 1-3 This embodiment proposes a multi-station rotary grinding equipment for strengthening the edge of a glass cover plate, including an equipment support 1, a support base 2 fixedly installed at the top of the equipment support 1, a grinding mechanism 3 installed on the support base 2, and an adjustment mechanism 4 installed on the grinding mechanism 3.

[0026] The shock-absorbing feet at the bottom of the equipment support 1 absorb the vibrations generated by high-speed rotation through internal damping material, preventing the vibrations from being transmitted to the machining interface. This further ensures transmission stability and prevents a decrease in machining accuracy due to vibration.

[0027] It should be noted that the bottom of the equipment bracket 1 is equipped with shock-absorbing feet, and the inside of the shock-absorbing feet is filled with damping material.

[0028] The grinding mechanism 3 includes a working motor 31, a first rotating disk 32, a chain belt 33, a second rotating disk 34, a rotating rod 35, an active drive disk 36, a drive belt 37, a driven drive disk 38, and a grinding disk 39; the rotating rod 35 and the second rotating disk 34 are coaxially fixedly connected by a keyway.

[0029] The working motor 31 is fixed to the bottom of the support base 2. The output shaft of the working motor 31 is connected to the first rotating disk 32. The first rotating disk 32 is connected to the second rotating disk 34 through the chain belt 33. The second rotating disk 34 is coaxially connected to a rotating rod 35. The surface of the rotating rod 35 is fitted with a mounting plate surface 351. An edge fixing rod 352 and a center fixing rod 353 pass through the mounting plate surfaces 351. The active drive disk 36 is fitted onto the surface of the rotating rod 35 and is connected to the driven drive disk 38 through the drive belt 37. The driven drive disk 38 is coaxially connected to a grinding disk 39.

[0030] The specific technical solution involves starting the working motor 31, whose output shaft drives the first rotating disk 32 to rotate. Power is transmitted to the second rotating disk 34 via a chain belt 33, causing the rotating rod 35 to rotate uniformly around its axis, achieving synchronous rotation across multiple stations. The active drive disk 36 on the side wall of the rotating rod 35 drives the driven drive disk 38 to rotate via a drive belt 37, which in turn drives the grinding disk 39 to rotate at high speed. The grinding surface of the grinding disk 39 contacts the edge of the glass cover plate, and the rotation of the grinding disk 39 creates relative motion, completing the uniform grinding and strengthening of the glass cover plate edge.

[0031] The adjustment mechanism 4 includes a fixed base 41, an adjusting screw 42, an adjusting base 43, a moving block 44, a moving groove 45, and a limiting roller 46. The fixed base 41 is fixed to the surface of the mounting plate 351. The adjusting screw 42 passes horizontally through the fixed base 41 and is threadedly connected to the adjusting base 43. The adjusting base 43 slides with the moving groove 45 through the moving block 44. The moving groove 45 is opened on the surface of the moving block 44. The limiting roller 46 is installed at the end of the moving block 44 to limit the radial displacement of the grinding disc 39.

[0032] Furthermore, the surface of the limiting roller 46 is covered with a rubber layer to buffer contact pressure.

[0033] Specifically, the adjusting mechanism 4 rotates the adjusting screw 42 to push the adjusting seat 43 to slide horizontally along the moving groove 45, thereby driving the moving block 44 and the limiting roller 46 to move synchronously, thus adjusting the radial position of the grinding disc 39. The rubber layer on the surface of the limiting roller 46 contacts the side wall of the grinding disc 39, limiting its radial displacement and buffering vibration to ensure stable grinding pressure.

[0034] The multi-station rotary grinding equipment of this utility model achieves efficient strengthening treatment of the glass cover edge through the following steps:

[0035] Multi-station synchronous drive:

[0036] The working motor 31 is started, and its output shaft drives the first rotating disk 32 to rotate. The power is transmitted to the second rotating disk 34 through the chain belt 33, which drives the rotating rod 35 to rotate at a constant speed around the axis, realizing synchronous rotation of multiple stations. The active drive disk 36 on the side wall of the rotating rod 35 drives the driven drive disk 38 to rotate through the drive belt 37, which in turn drives the grinding disk 39 to rotate at high speed. The grinding surface of the grinding disk 39 contacts the edge of the glass cover plate. The rotation of the grinding disk 39 creates relative motion, completing the uniform grinding and strengthening of the edge of the glass cover plate.

[0037] Precise adjustment and limit:

[0038] The adjustment mechanism 4, by rotating the adjustment screw 42, pushes the adjustment seat 43 to slide horizontally along the moving groove 45, thereby driving the moving block 44 and the limiting roller 46 to move synchronously, thus adjusting the radial position of the grinding disc 39. The rubber layer on the surface of the limiting roller 46 contacts the side wall of the grinding disc 39, limiting its radial displacement and buffering vibration to ensure stable grinding pressure.

[0039] Vibration reduction and dynamic balance:

[0040] The shock-absorbing feet at the bottom of the equipment support 1 absorb the vibrations generated by high-speed rotation through internal damping material, preventing the vibrations from being transmitted to the machining interface. This further ensures transmission stability and prevents a decrease in machining accuracy due to vibration.

[0041] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
