Description

Technical Field

[0001] The present invention relates to the technical field of trolleys, in particular to an optical lens transport trolley. Background Art

[0002] The transfer trolley is a core tool for connecting various processes in the production of optical lenses. As a dedicated transportation equipment for optical lens placement racks, it ensures that the lenses remain level and stable during transportation through customized placement slots. It connects the injection molding station with the heating and curing process, realizing the integrated operation of "injection molding completed → loading the placement rack → pushing the trolley → sending it to the heating chamber", shortening the connection time between processes and improving overall production efficiency.

[0003] When existing staff push the transfer cart, they will accelerate too quickly over a short distance due to a short and rapid push. At this time, the inertia is relatively large. The inertia generated by the short and rapid acceleration causes the optical lenses in the placement rack to fall out of the fixed slot due to excessive shaking, causing the lenses to fall, bump or scratch. If the entire row of lenses falls off at the same time due to inertia, the entire batch of products will be scrapped directly, and re-injection production will be required, which greatly increases the cost. When the lenses fall, they will stick and break due to the uncured resin. The flying fragments or resin residues can easily scratch the operator's hands or face. After the lenses fall off, the machine needs to be stopped to clean the site and reload the lenses. In addition, the shaking causes uneven distribution of the resin, which causes stress deformation or degradation of optical performance after curing, resulting in hidden defective products. Summary of the Invention

[0006] Furthermore, an oil pump is installed on the bottom surface of the transfer trolley, and hydraulic oil pipes are evenly distributed on the outer surface of the oil pump, wherein one end surface of eight of the hydraulic oil pipes extends to the interior of the hydraulic cavity.

[0007] Furthermore, the limiting and deflecting assembly includes a limiting plate and two deflecting cavities. The limiting plate is installed on the outer surface of the main bracket, and two deflecting cavities are provided inside the limiting plate.

[0008] Furthermore, a front deflection frame is installed on the outer surface of the cylindrical frame, and a rear deflection frame is installed on the outer surface of the cylindrical frame.

[0009] Furthermore, two return springs 1 are installed on the inner walls of the two deflection chambers, and limit blocks are installed on the outer surfaces of the four return springs 1.

[0010] Furthermore, sponge blocks are installed on the outer surfaces of the two limit blocks, and the outer surfaces of the four sponge blocks are in movable contact with the outer surfaces of the front deflection frame and the outer surfaces of the rear deflection frame respectively, and the outer surfaces of the limit blocks are in movable contact with the inner wall of the deflection cavity.

[0011] Furthermore, the fixing assembly includes two placement slots and a placement rack. The interior of the transfer trolley is provided with a placement slot, and the placement rack is movably installed on the inner walls of the two placement slots.

[0012] Furthermore, two fixing grooves are provided inside the transfer trolley, a fixing rod is installed inside the transfer trolley, one end surface of the hydraulic oil pipe extends to the inside of the fixing rod, and a plurality of piston push rods 2 are movably installed inside the fixing rod.

[0013] Furthermore, the inner walls of the two fixing grooves are evenly distributed with reset springs 2, and the outer surfaces of several reset springs 2 are installed with rubber fixing blocks, and the outer surfaces of the rubber fixing blocks are in movable contact with the inner walls of the fixing grooves, and the outer surfaces of the rubber fixing blocks are in movable contact with the outer surface of the placement rack.

[0014] The present invention has the following beneficial effects: 1. The optical lens transfer trolley squeezes the wheel hub through the ball shaft, and the wheel hub causes the ball shaft to rotate in the ball groove, thereby slowing down the acceleration of the wheel hub and preventing the placement rack from shaking due to sudden braking of the wheel hub, thereby preventing the optical lenses on the placement rack from shaking. During braking, the ball shaft and the wheel hub form point contact, and the rotation of the wheel hub drives the ball shaft to rotate, converting sliding friction into rolling friction, reducing the friction coefficient, and establishing rolling contact between the ball shaft and the wheel hub, slowing down the acceleration. The displacement amplitude of the optical lens due to inertia is reduced, avoiding collision with the inner wall of the placement rack or fixed structure, and fundamentally reducing the risk of falling off. The smooth acceleration control makes personnel operation more relaxed, reduces the risk of accidental collision caused by sudden stopping and starting, and reduces the maintenance cost of recalibration or cleaning after the optical lens falls off.

[0015] 2. The optical lens transfer trolley drives the front deflection frame and the rear deflection frame to perform angular deflection in the deflection cavity through the cylindrical frame. The front deflection frame and the rear deflection frame squeeze different sponge blocks, so that the sponge blocks drive the limit blocks to squeeze the reset spring 1, thereby slowing down the large-angle deflection, thereby reducing the impact of excessive turning on the optical lenses in the placement rack. The compression deformation of the sponge block and the elastic deformation of the reset spring 1 form a double buffer layer, which gradually absorbs the kinetic energy generated by the deflection and avoids the rigid impact from being directly transmitted to the optical lens placement rack. The larger the deflection angle, the exponential increase in the sponge density change and the spring compression force, which suppresses the operator's unconscious sharp turning action and prevents the optical lenses on the placement rack from shaking.

[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

The inner walls of the two ball grooves 3016 are both installed with ball shafts 3017. The outer surfaces of the limiting blocks 3015 are in active contact with the inner walls of the movable grooves 3013. The ball shaft 3017 on the outside of the brake disc 309 squeezes the wheel hub 303, and when the wheel hub 303 moves, the wheel hub 303 causes the ball shaft 3017 to rotate in the ball groove 3016, thereby slowing down the acceleration of the wheel hub 303, and does not cause the wheel hub 303 to brake suddenly and cause the placement rack 7 to shake, thereby preventing the optical lens on the placement rack 7 from shaking, and the ball shaft 3017 is made of high-hardness alloy steel with chrome-plated surface, and the ball groove 3016 is filled with high-temperature grease.

The outer surface of the main bracket 301 is equipped with a limit plate 4, and the inner surface of the limit plate 4 is provided with two deflection cavities 401. The outer surface of the cylindrical frame 302 is equipped with a front deflection frame 402. The outer surface of the cylindrical frame 302 is installed with a rear deflection frame 403. Two return springs 406 are installed on the inner walls of the two deflection chambers 401. The outer surfaces of the four return springs 406 are installed with limit blocks 404. The outer surfaces of the two limit blocks 404 are installed with sponge blocks 405.

The inner wall of the cavity 401 is in movable contact, and the outer surface of the limit block 404 is in movable contact with the inner wall of the deflection cavity 401. When the staff pushes the transfer trolley 1 for angle deflection, the cylindrical frame 302 drives the front deflection frame 402 and the rear deflection frame 403 to perform corresponding angle deflection in the deflection cavity 401, and the front deflection frame 402 and the rear deflection frame 403 squeeze different sponge blocks 405 accordingly, so that the sponge block 405 drives the limit block 404 to squeeze the return spring 406, thereby slowing down the large-scale angle deflection, thereby reducing the impact of excessive turning on the optical lens in the placement rack 7, the compression deformation of the sponge block 405 and the elastic deformation of the return spring 406 form a double buffer layer, which gradually absorbs the kinetic energy generated by the deflection, and avoids the rigid impact directly transmitted to the optical lens placement rack 7, and the larger the deflection angle, the exponential increase of the sponge density change and the spring compression force, which suppresses the operator's unconscious sharp turning action, thereby preventing the optical lens on the placement rack 7 from shaking.

[0023] The fixed component includes two placement slots 5 and a placement rack 7. The interior of the transfer trolley 1 is provided with a placement slot 5. The inner walls of the two placement slots 5 are movably installed with a placement rack 7. The interior of the transfer trolley 1 is provided with two fixed slots 802. The interior of the transfer trolley 1 is provided with a fixed rod 8. One end surface of the hydraulic oil pipe 3011 extends to the interior of the fixed rod 8. The interior of the fixed rod 8 is movably installed with a plurality of piston push rods 801. The inner walls of the two fixed slots 802 are evenly distributed with reset springs 803. The plurality of reset springs 803 are arranged on the inner walls of the two fixed slots 802. A rubber fixing block 804 is installed on the outer surface. The outer surface of the rubber fixing block 804 is in movable contact with the inner wall of the fixing groove 802.

When the transfer trolley 1 is accelerated, the placement rack 7 is immediately fixed, thereby protecting the optical lens of the placement rack 7 from multiple directions.

[0024] The working process of the present invention is as follows: when optical lenses are produced, the optical lenses after resin injection need to be placed in the placement rack 7, and when the placement rack 7 is pushed into the placement slot 5 in the transfer trolley 1, the staff pushes the transfer trolley 1 to push the placement rack 7 into the heating chamber. When the placement rack 7 is pushed into the placement slot 5, the staff pushes the transfer trolley 1 through the handle 2. When the staff pushes the transfer trolley 1 to increase the speed, when the signal detected by the acceleration sensor 9 at this time exceeds the set safety value, the acceleration sensor 9 transmits the signal to the controller 6, and the controller 6 controls the oil pump 3012 to work, and the oil pump 3012 is pressurized, and hydraulic energy is provided to the hydraulic cavity 307 and the fixed rod 8 of the hydraulic brake disc 306 through the hydraulic oil pipe 3011. The hydraulic energy drives a plurality of piston push rods 3010 and a plurality of piston push rods 801 to move.

[0025] Several piston push rods 3010 push eight brake discs 309, and the brake discs 309 move on the limiting guide pillars 308, so that the brake discs 309 squeeze the wheel hub 303. First, the ball shaft 3017 outside the brake disc 309 squeezes the wheel hub 303, and in the process of the wheel hub 303 moving, the wheel hub 303 causes the ball shaft 3017 to rotate in the ball groove 3016, so that the wheel hub 303 slows down the acceleration, and does not cause the wheel hub 303 to brake suddenly and cause the placement rack 7 to shake, thereby preventing the optical lens on the placement rack 7 from shaking. The ball shaft 3017 is made of high-hardness alloy steel, and the surface Chrome-plated, the ball groove 3016 is filled with high-temperature grease. During braking, the ball shaft 3017 forms point contact with the wheel hub 303. The rotation of the wheel hub 303 drives the ball shaft 3017 to rotate, converting sliding friction into rolling friction. The friction coefficient is reduced, and the ball shaft 3017 establishes rolling contact with the wheel hub 303, which slows down the acceleration. The displacement amplitude of the optical lens due to inertia is reduced, avoiding collision with the inner wall of the placement rack 7 or the fixed structure, fundamentally reducing the risk of falling off. The smooth acceleration control makes the operator more relaxed, reduces the risk of accidental collision due to sudden stop and start, and reduces the maintenance cost of recalibration or cleaning after the optical lens falls off.

[0026] When the staff pushes the transfer trolley 1 for angle deflection, the cylindrical frame 302 drives the front deflection frame 402 and the rear deflection frame 403 to perform corresponding angle deflection in the deflection cavity 401, and the front deflection frame 402 and the rear deflection frame 403 squeeze the different sponge blocks 405, so that the sponge block 405 drives the limit block 404 to squeeze the return spring 406, thereby slowing down the large angle deflection, thereby reducing the impact of excessive turning on the optical lens in the placement rack 7, the compression deformation of the sponge block 405 and the elastic deformation of the return spring 406 form a double buffer layer, which gradually absorbs the kinetic energy generated by the deflection, and avoids the rigid impact directly transmitted to the optical lens placement rack 7, and the larger the deflection angle, the exponential increase of the sponge density change and the spring compression force, which suppresses the operator's unconscious sharp turning action, thereby preventing the optical lens on the placement rack 7 from shaking.

[0027] And several piston push rods 801 push the rubber fixing block 804 synchronously, so that the rubber fixing block 804 squeezes and fixes the placement rack 7, so that the placement rack 7 is fixed in the placement groove 5. When the transfer trolley 1 is accelerated, the placement rack 7 is immediately fixed, thereby protecting the optical lens of the placement rack 7 in multiple directions. There is active contact between the piston push rod 801 and the rubber fixing block 804, so that it is reset by the reset spring 803, so that the rubber fixing block 804 is reset after the end.
