Description

Technical Field

[0001] The present invention relates to the technical field of tempered glass processing, and more particularly to a tempered glass processing and feeding device. Background Art

[0002] In the field of modern tempered glass processing industry, the loading link is the starting process of the entire production line. Its operation convenience and stability are directly related to the efficiency of the subsequent processing flow and the quality of the finished product. The current tempered glass processing loading device generally uses a special loading car as a transportation tool. Its workflow usually includes placing the tempered glass sheet on the loading car, temporarily fixing it with a suction cup system, and then transporting the glass to the designated workstation. Finally, external equipment such as a robotic arm or a conveyor belt transfers the glass to the next processing link. However, a common problem in the existing technology is that the suction cup fixing system is not designed reasonably. Most of them use a single independent working suction cup. The glass is fixed by a suction cup. This single suction cup design has defects in actual operation. When the staff places the tempered glass sheet on the loading car, once the glass contacts the surface of the suction cup, the suction cup starts to generate adsorption force, firmly sucking the local area of the glass. This instant adsorption mechanism seems efficient, but the glass is partially fixed before the precise positioning is completed, making it impossible for the staff to make subtle adjustments or corrections to the position of the glass. Especially for large-sized or heavy tempered glass, this operation of adjusting the position after partial fixation is almost impossible to achieve, which not only increases the difficulty of operation, but may also reduce the subsequent processing accuracy due to improper positioning.

[0003] Further analysis shows that the design defects of this single suction cup instant adsorption are particularly prominent in daily production. When the operator tries to place the tempered glass on the loading cart, he needs to control the speed and angle of the glass's descent extremely carefully to avoid the glass from contacting the suction cup too early and being fixed in an undesirable position. This working method that is highly dependent on operating skills not only increases the workers' psychological burden and labor intensity, but also significantly prolongs the loading preparation time. This traditional single suction cup instant adsorption loading device design is increasingly unable to adapt to the needs of industry development. Technological innovation is urgently needed to improve operational convenience and production efficiency, reduce dependence on manual labor, and realize the modernization and intelligent upgrading of the tempered glass processing and loading links. Summary of the Invention

[0004] (1) Technical problems solved

[0005] In view of the problems existing in the prior art, the present invention provides a tempered glass processing and loading device to solve the technical problems mentioned in the background technology.

[0006] (2) Technical solution

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a tempered glass processing and feeding device, comprising a feeding trolley and a plurality of side panels installed on both sides of the feeding trolley; further comprising a mounting mechanism, wherein the mounting mechanism comprises a bottom tube installed on the plurality of side panels, a sealing sleeve is coaxially arranged on the bottom tube, a plurality of transverse tubes are installed on the side wall of the sealing sleeve, and a transverse hole is opened on the sealing sleeve, the transverse tubes are connected to the sealing sleeve through the transverse hole, a connecting tube is installed between two of the sealing sleeves, a vertical tube is vertically arranged on each of the transverse tubes, a cutting rod is slidably connected in each of the vertical tubes, a push spring is installed on each of the cutting rods, and a plurality of push springs are respectively connected to the bottom tube; further comprising an exhaust mechanism, the exhaust mechanism comprises an extension tube connected and installed on the sealing sleeve, and the extension tube is slidably connected to the bottom tube.

[0008] Preferably, the mounting mechanism also includes a piston disc sealingly and slidingly connected to the sealing sleeve, and a return spring is installed at the lower end of the piston disc, and the return spring is connected to the sealing sleeve. This design constitutes the core component of the entire negative pressure generation. The piston disc can slide in the sealing sleeve without leaking gas, ensuring that the system can reliably generate negative pressure.

[0009] Preferably, a suction cup is installed in communication with the sealing sleeve, a pressure rod is installed coaxially on the piston disc, and the upper end of the pressure rod passes through the upper end of the suction cup, a plurality of ventilation grooves are provided at equal intervals on the side wall of the pressure rod, and the pressure rod passes through the upper end of the suction cup and protrudes a certain distance, ensuring that the tempered glass initially contacts only the pressure rod and not the suction cup, thereby providing the operator with a time window for accurately adjusting the position of the glass.

[0010] Preferably, a plurality of guide rods are installed at equal intervals on the bottom tube, and a plurality of guide sleeves are installed at equal intervals on the side wall of the sealing sleeve. The guide rods are slidably connected to the guide sleeves. This set of guide mechanisms provides precise guidance and smooth support for the vertical movement of the sealing sleeve. The plurality of guide rods are distributed at equal intervals on the bottom tube, and form a sliding fit with the corresponding guide sleeves on the side wall of the sealing sleeve, thereby ensuring that the sealing sleeve can move strictly in the vertical direction when it is pressed down by the weight of the glass.

[0011] Preferably, a reinforcing plate is installed on each of the vertical tubes, and a limiting ring coaxially arranged with the sealing sleeve is installed on the upper ends of the plurality of vertical tubes.

[0012] Preferably, the exhaust mechanism also includes a one-way groove provided at the upper end of the extending tube, a one-way disc being fitted on the one-way groove, a bottom spring being fitted on the lower end of the sealing sleeve, and the bottom spring being in contact with the bottom tube. This exhaust mechanism solves the problem of gas circulation control in the system. The cooperation between the one-way groove and the one-way disc forms a one-way valve, which allows the air below to be discharged while preventing external air from entering during the downward movement of the piston disc, thereby ensuring the effective formation and maintenance of negative pressure.

[0013] Preferably, an exhaust pipe is installed at the lower end of the piston disc, the one-way disc is slidably connected to the one-way disc, a top spring is sleeved on the exhaust pipe, and the upper end of the top spring abuts against the one-way disc. This design constitutes a precise air pressure regulation system, and the exhaust pipe installed at the lower end of the piston disc is directly connected to the exhaust path, ensuring the smoothness of gas flow; the sliding connection design between the one-way disc and the exhaust pipe enables the one-way disc to move flexibly under the action of pressure difference, thereby realizing precise airflow control.

[0014] Preferably, a micro-hole is provided in the exhaust pipe, and the micro-hole is connected between the lower end of the piston disc and the lower end of the exhaust pipe.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the present invention provides a tempered glass processing and feeding device with the following features:

[0017] Beneficial effects:

[0018] The device uses a combination of pressure rods and suction cups with staggered heights to ensure that when the tempered glass first contacts the loading device, it only contacts the protruding pressure rods and is not immediately fixed by the suction cups. This design provides operators with a valuable time window for position adjustment, allowing workers to precisely adjust the position and angle of the glass before it is completely fixed, thereby improving the flexibility and accuracy of the loading process. Especially for large or specially shaped tempered glass, this adjustable performance significantly reduces processing defects and material waste caused by position deviation, thereby improving overall production efficiency and product qualification rate.

[0019] The negative pressure generating system of the device adopts the volume change principle of the piston disc and the sealing sleeve, rather than the traditional external vacuum equipment, to achieve self-driven adsorption without external energy. When the tempered glass is gradually pressed down, the pressure rod is pushed to drive the piston disc downward, and a negative pressure area is naturally formed under the sealed state, so that the suction cup is firmly adsorbed on the glass surface. This design of converting mechanical energy into adsorption force not only simplifies the system structure and reduces energy consumption, but also improves system reliability and reduces failure points. At the same time, the setting of the reset spring ensures that the piston disc can return to its position smoothly during the release process, preparing for the next operation, thereby improving the recycling efficiency of the equipment.

[0020] Through the layout of horizontal tubes and connecting tubes, combined with the control of the cutting rod, the system can start the sealing process only after the tempered glass is pressed down to the appropriate position, avoiding premature adsorption. Multiple suction cups form a communication network through connecting tubes, ensuring that the system will not start negative pressure adsorption until all suction cups are completely in contact with the glass surface. This design solves the positioning difficulty problem caused by premature adsorption of a single suction cup in traditional equipment. Especially for glass with an imperfect surface, this full-system linkage mechanism can ensure uniform adsorption, prevent local stress concentration, and significantly improve fixation stability and safety.

[0021] In terms of safety, the device achieves a smooth release of adsorption force through the design of micropores and one-way valves. When the fixed state is released, the micropores limit the air inflow speed, so that the adsorption force of the suction cup gradually weakens instead of disappearing instantly, effectively preventing safety accidents and material losses caused by the sudden loss of adsorption force and the falling of tempered glass. At the same time, the setting of the one-way valve ensures the one-way flow of gas during the adsorption process, maintaining a stable negative pressure, and can control the airflow rate during the release process. This two-way control mechanism greatly improves operational safety and process controllability. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] See also Figures 1 to 8, a tempered glass processing and feeding device includes a feeding car 11 and multiple side plates 12 installed on both sides of the feeding car 11; it also includes a mounting mechanism, the mounting mechanism includes a bottom tube 21 installed on the multiple side plates 12, a sealing sleeve 22 is coaxially provided on the bottom tube 21, a plurality of transverse tubes 23 are installed on the side wall of the sealing sleeve 22, and a transverse hole 24 is opened on the sealing sleeve 22, the transverse tube 23 is connected to the sealing sleeve 22 through the transverse hole 24, a connecting tube 25 is installed between the two sealing sleeves 22, each transverse tube 23 is vertically provided with a vertical tube 26, each vertical tube 26 is slidably connected to a cutting rod 27, each cutting rod 27 is respectively installed with a push spring 28, and multiple push springs 28 are respectively connected to the bottom tube 21, the mounting mechanism also includes A piston disc 29 is sealed and slidably connected to the sealing sleeve 22. A return spring 210 is installed at the lower end of the piston disc 29. The return spring 210 is connected to the sealing sleeve 22. A suction cup 211 is installed on the sealing sleeve 22. A pressure rod 212 is coaxially installed on the piston disc 29, and the upper end of the pressure rod 212 passes through the upper end of the suction cup 211. A plurality of ventilation grooves 213 are evenly spaced on the side wall of the pressure rod 212. A plurality of guide rods 214 are evenly spaced on the bottom tube 21. A plurality of guide sleeves 215 are evenly spaced on the side wall of the sealing sleeve 22. The guide rods 214 are slidably connected to the guide sleeves 215. A reinforcing plate 216 is respectively installed on each vertical tube 26, and a limit ring 217 coaxially arranged with the sealing sleeve 22 is installed on the upper end of the plurality of vertical tubes 26.

[0035] When the tempered glass needs to be placed on the loading car 11, the tempered glass is first extended into the upper ends of the multiple suction cups 211 by the mechanical arm and then lowered. Since the length of the pressure rod 212 is greater than the length of the suction cup 211, the tempered glass will first be pressed on the multiple pressure rods 212. At this time, all the weight of the tempered glass has not been pressed on the pressure rod 212 and the suction cup 211, so the pressure rod 212 will be slowly pressed downward until the multiple suction cups 211 fit on the side wall of the tempered glass. As it continues to move downward, the bottom spring 34 presses on the bottom tube 21 and the sealing sleeve 22, so it will be compressed downward. At this time, the cutting rod 27 will move upward relative to the sealing sleeve 22, and then the cutting rod 27 will seal the transverse tube 23 without the connecting tube 25. At this time, the sealing sleeve 22 is in a sealed state, and then As the rear tempered glass continues to move downward, it presses on the pressure rod 212, causing the piston disc 29 to slide downward. Therefore, the space at the upper end of the piston disc 29 becomes larger, and the gas between the suction cup 211 and the tempered glass is sucked into the upper end of the piston disc 29 through the vent groove 213. Since the gas between the suction cup 211 and the piston disc 29 is constant at this time, but the volume of the upper end of the piston disc 29 increases when the piston disc 29 moves downward, negative pressure is generated, causing the suction cup 211 to be adsorbed on the side wall of the tempered glass, ensuring the stability of adsorption. As the tempered glass puts all its weight on the pressure rod 212 and the suction cup 211, the tempered glass will be pressed on the limit ring 217, and the negative pressure in the suction cup 211 will reach the maximum, thus ensuring stable adsorption.

[0036] As the piston disc 29 moves downward, the air at the lower end of the piston disc 29 will be discharged. Since the pressure at the lower end of the piston disc 29 increases when moving downward, the seal between the one-way disc 33 and the one-way groove 32 will be released, and then the gas will be discharged into the extension tube 31 and then discharged, thus avoiding the air pressure at the lower end of the piston disc 29 affecting the adsorption effect of the suction cup 211.

[0037] Since the multiple sealing sleeves 22 are connected through the connecting tube 25, if the tempered glass is not installed correctly and some suction cups 211 are not effectively sealed with the tempered glass, as the piston plate 29 moves downward, air will be sucked in through the suction cup 211 that is not sealed, so no negative pressure will be generated, avoiding the adsorption of a single suction cup 211 affecting secondary adjustment, thereby improving convenience of use.

[0038] When the tempered glass is just attached to the pressure rod 212, the sealing sleeve 22 has not yet moved downward. Since there are four transverse tubes 23, not all transverse tubes 23 are installed with connecting tubes 25. The other transverse tubes 23 without connecting tubes 25 are connected to the outside and are not sealed. At this time, as the tempered glass continues to move downward, the sealing sleeve 22 moves downward. The sealing sleeve 22 is not sealed and no negative pressure adsorption is generated. Because the cutting rod 27 moves upward relative to the sealing sleeve 22 as the sealing sleeve 22 moves downward under the action of the push spring 28, when the cutting rod 27 is in the state without connecting tubes 25, In the transverse tube 23, as the cutting rod 27 continues to move, the vertical tube 26 and the transverse tube 23 will be sealed, and then a sealed state will be reached. At this time, it will continue to move downward to perform a negative pressure adsorption state. When the cutting rod 27 is in the transverse tube 23 with the connecting tube 25, the cutting rod 27 will press against the connecting tube 25 as it continues to move, and the push spring 28 will continue to be compressed, which will not have any effect and will only cause the push spring 28 to be compressed. Therefore, the transverse tube 23 without the connecting tube 25 will be sealed by multiple cutting rods 27. Therefore, the sealing of the sealing sleeve 22 is guaranteed under the action of the cutting rod 27 to ensure the effect of negative pressure adsorption.

[0039] The exhaust mechanism includes an extension tube 31 connected and installed on the sealing sleeve 22, and the extension tube 31 is slidably connected to the bottom tube 21. The exhaust mechanism also includes a one-way groove 32 opened at the upper end of the extension tube 31, and a one-way disc 33 is fitted on the one-way groove 32. A bottom spring 34 is installed at the lower end of the sealing sleeve 22, and the bottom spring 34 abuts on the bottom tube 21. An exhaust pipe 35 is installed at the lower end of the piston disc 29, and the one-way disc 33 is slidably connected to the one-way disc 33. A top spring 36 is sleeved and installed on the exhaust pipe 35, and the upper end of the top spring 36 abuts on the one-way disc 33. A microflow hole 37 is opened in the exhaust pipe 35, and the microflow hole 37 is connected to the lower end of the piston disc 29 and the lower end of the exhaust pipe 35.

[0040] When the connection needs to be released, the tempered glass is pulled upward. Due to the one-way setting between the one-way disc 33 and the one-way groove 32, when the piston disc 29 moves upward, the air inhaled into the space at the lower end of the piston disc 29 needs to flow inward through the micro-holes 37. Since the micro-holes 37 are very small, the air flows in very slowly, thereby avoiding the sudden disappearance of the suction force of the suction cup 211. The safety of the operation is improved through a slow process, and when moving upward, the cutting rod 27 will be pulled downward under the action of the push spring 28, and then the transverse tube 23 without the connecting tube 25 will be unsealed, and then the air will flow into the piston disc 29. At this time, the negative pressure will be released, thereby completing the unfastening process of the tempered glass.

[0041] In all the schemes mentioned above, the connection between the two parts can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be described here one by one. In the above, all fixed connections are preferably considered to be welding.
