Description

Technical Field

[0001] The present invention belongs to the field of safety protection doors, and specifically relates to a safety protection door for robot operation. Background Art

[0002] Generally, the use of safety doors in an automated workshop can help enterprises improve work efficiency. Robot safety doors have functions such as sound insulation, protection, and dust prevention. In addition, the safety door can also communicate with the robot, open and close in a fully automatic mode, protect the staff and the machine, and isolate harmful substances emitted during welding.

[0003] During the operation of the internal equipment of traditional protection doors, a large amount of heat and vibration will be generated. It is difficult to meet the normal heat dissipation solely by external gas. Moreover, when the equipment uses external air flow for heat dissipation, not only a large amount of heat needs to be consumed, but also external dust will be brought into the equipment interior, causing equipment pollution and blockage. High-frequency vibration will also cause gaps in the equipment, resulting in the separation of internal parts and external workpieces, generating danger. Summary of the Invention

[0006] Reinforcing ribs are fixedly connected to the inner surface of the protection door, an observation window is arranged outside the reinforcing ribs, a protection mechanism is arranged inside the observation window, and the lower surface of the protection mechanism is fixedly connected to the upper surface of the reinforcing ribs.

[0007] The protection mechanism includes a pressure tank. A connecting pipe is fixedly connected to the bottom end of the pressure tank. A fixed box is fixedly connected to the left end of the connecting pipe. An inclined plate is rotatably connected to the inner surface of the fixed box. A pressing plate is slidably connected to the inner surface of the top of the inclined plate. The outer surface of the pressing plate is slidably connected to the inner surfaces of the inclined plate and the fixed box. A compression spring is fixedly connected to the upper surface of the pressing plate. The top end of the compression spring is fixedly connected to a fixed rod. The outer surface of the fixed rod is slidably connected to the inner surface of the pressing plate. The bottom end of the fixed rod is fixedly connected to the inner surface of the fixed box.

[0008] The heat dissipation mechanism includes an outer cover. A speed reduction plate is fixedly connected to the inner surface of the outer cover. A water outlet pipe is arranged at the top of the speed reduction plate. The bottom end of the water outlet pipe is fixedly connected to the upper surface of the outer cover. The top end of the water outlet pipe is fixedly connected to a water tank. Heat dissipation fins are fixedly connected to the outer surface of the water tank. A water injection pipe is arranged at the top of the heat dissipation fins. The bottom end of the water injection pipe is fixedly connected to the upper surface of the water tank. A water inlet pipe is fixedly connected to the lower surface of the water tank. A return pipe is fixedly connected to the back of the water inlet pipe. The left end of the return pipe is fixedly connected to the outer surface of the water tank. The right end of the return pipe is fixedly connected to the outer surface of the cabinet body.

[0009] The air intake mechanism includes an air inlet pipe. A filter element is fixedly connected to the bottom end of the air inlet pipe. A fixed block is fixedly connected to the inner surface on the right side of the filter element. A conical block is arranged on the left side of the fixed block. A return spring is fixedly connected to the outer surface on the left side of the conical block. The left end of the return spring is fixedly connected to the inner surface of the filter element.

[0010] The beneficial effects of the present invention are as follows: 1. By providing a protection door in the present invention, when the equipment is in use, the rollers on the upper surface of the protection door rotate, and the inner surface of the protection door slides outwards along the outer surface of the sliding rod, and the cabinet body opens. In an artificial or manual manner, an object is placed on the upper surface of the operating table. The rollers rotate in the reverse direction, and the protection door closes. During the movement of the rollers and the sliding rod, the speed is stable and the vibration is small. The protection door and the cabinet body will not generate large friction gaps due to vibration. The working conditions on the upper surface of the operating table are observed through the observation window, solving the problem that the protection door of the traditional robot during work uses hinges to open and close, and the equipment is prone to generate friction gaps.

[0011] 2. The present invention provides a protective mechanism. Since double-layer sealed glass is fixedly installed on both sides of the protective door, and the inner interlayer of the glass is evacuated to a vacuum state, when the protective door is in a normal working state, the outer surfaces of the two sides of the inclined plate are in contact and extrusion with the inner surface of the glass, and the outer surface of the inclined plate is in contact with the inner surface of the fixed box. Under the restriction of the compression spring, the lower surface of the pressure plate is in contact with the upper surface of the inclined plate. The protective mechanism is in a two-force balance state under the action of the clamping force of the glass and the downward pressure of the compression spring. The fixed box is sealed. When the workpiece inside the cabinet suddenly flies out, the glass is shattered, the force balance of the protective mechanism is broken, the external pressure of the inclined plate is suddenly reduced, the compression spring presses the pressure plate downward, the inclined plate rotates, the fixed box opens, the pressure at the bottom end of the connecting pipe drops, and the pressure tank presses the non-Newtonian fluid inside it from the connecting pipe to the inside of the fixed box, and the fluid is ejected. The ejected fluid is entangled with the broken glass and the workpiece. Under the wrapping of the fluid, the scattering range of the fragments is reduced, the damage range of the fragments splashing is reduced, the safety is improved, and the problem that the traditional protective door has poor protection effect and the fragments are easy to splash is solved.

[0012] 3. The present invention sets an air intake mechanism. When the equipment is in use, the mechanical and electrical units inside the equipment will release heat outward. Since the interior of the cabinet is in a sealed state, the heat cannot be dissipated in time. At this time, the air intake pipe injects cold air into the interior of the equipment. Driven by the airflow, the conical block moves to the left, the return spring is compressed, the gap between the fixed block and the conical block increases, and air flows in. The filter element filters and purifies the inhaled air to prevent dust from polluting the interior of the equipment. The hot air eventually pushes open the cover plate with a part of the heat and is discharged from the air outlet slot. The air intake mechanism can prevent the interior of the equipment from being blocked while assisting in cooling, thereby solving the problem that the interior of the traditional protective door is easily contaminated and blocked by external dust when assisting in heat dissipation.

[0013] 4. The present invention sets a heat dissipation mechanism. When the air intake mechanism cannot meet the heat dissipation of the equipment, the water injection pipe injects cooling water into the water tank, and the cold water moves from the water inlet pipe to the inside of the outer cover. Because the water flow needs to climb over the speed reducer one by one to reach the water outlet pipe, the water flow rate is reduced under the action of the speed reducer, and the residence time of the water flow inside the outer cover is prolonged. The heat exchange efficiency is increased by increasing the heat exchange time. The hot water that completes the heat conversion flows out from the water outlet pipe to the inside of the water tank, and the return pipe transfers the heat from other areas of the equipment to the water tank. The temperature of the water tank rises, and the heat is diffused to the outside under the action of the heat sink. In this cycle, the equipment uses the internal water circulation to keep the temperature constant, which solves the problem that the internal heat dissipation of traditional industrial equipment requires a large amount of external energy.

Specific embodiments

[0016] Use Figures 1 - 6 A safety protection door for robot operation according to an embodiment of the present invention will be described as follows.

[0017] As Figures 1 - 6 shown, a safety protection door for robot operation according to the present invention includes a cabinet body 1; the front surface of the cabinet body 1 is slidably connected with a protective door 3 through a slide bar 2, the left end of the slide bar 2 is fixedly connected with the outer surface of the cabinet body 1, the back surface of the protective door 3 is slidably connected with the front surface of the cabinet body 1, the inner surface of the cabinet body 1 is fixedly connected with an operating table 4, the bottom of the operating table 4 is provided with an air intake mechanism 5, the outer surface of the air intake mechanism 5 is fixedly connected with the inner surface of the cabinet body 1, an air outlet groove 6 is opened on the outer surface of the left side of the cabinet body 1, a cover plate 7 is arranged on the outer surface of the air outlet groove 6, and a heat dissipation mechanism 8 is arranged on the top of the cover plate 7.

[0018] The inner surface of the protective door 3 is fixedly connected with a reinforcing rib 10, an observation window 11 is arranged outside the reinforcing rib 10, a protection mechanism 12 is arranged inside the observation window 11, and the lower surface of the protection mechanism 12 is fixedly connected with the upper surface of the reinforcing rib 10. By providing the protective door 3, when the equipment is in use, the rollers on the upper surface of the protective door 3 rotate, and the inner surface of the protective door 3 slides outwards along the outer surface of the slide bar 2, and the cabinet body 1 is opened. By means of manual or manual method, the object is placed on the upper surface of the operating table 4, the rollers rotate in the reverse direction, the protective door 3 closes, and the rollers and the slide bar 2 are stable in speed and have less vibration during the movement process. The protective door 3 and the cabinet body 1 will not generate large friction gaps due to vibration. The working condition on the upper surface of the operating table 4 is observed through the observation window 11, which solves the problem that the protective door of the traditional robot work uses hinges to open and close, and the equipment is prone to generate friction gaps.

[0019] The protection mechanism 12 includes a pressure tank 13. A connecting pipe 14 is fixedly connected to the bottom end of the pressure tank 13. A fixed box 15 is fixedly connected to the left end of the connecting pipe 14. An inclined plate 16 is rotatably connected to the inner surface of the fixed box 15. A pressing plate 17 is slidably connected to the inner surface at the top of the inclined plate 16. The outer surface of the pressing plate 17 is slidably connected to the inner surfaces of the inclined plate 16 and the fixed box 15. A compression spring 18 is fixedly connected to the upper surface of the pressing plate 17. The top end of the compression spring 18 is fixedly connected to a fixed rod 19. The outer surface of the fixed rod 19 is slidably connected to the inner surface of the pressing plate 17. The bottom end of the fixed rod 19 is fixedly connected to the inner surface of the fixed box 15. By providing the protection mechanism 12, since double-layer sealed glass is fixedly installed on both sides of the protection door 3 and the inner layer of the glass is pumped to a vacuum state, when the protection door 3 is in a normal working state, the outer surfaces on both sides of the inclined plate 16 contact and press against the inner surface of the glass, and the outer surface of the inclined plate 16 fits against the inner surface of the fixed box 15. Under the restriction of the compression spring 18, the lower surface of the pressing plate 17 fits against the upper surface of the inclined plate 16. The protection mechanism 12 is in a state of two-force balance under the clamping force of the glass and the downward pressure of the compression spring 18, and the fixed box 15 is sealed. When the workpiece inside the cabinet 1 suddenly flies out, the glass is broken, the force balance of the protection mechanism 12 is broken, the external pressure of the inclined plate 16 suddenly decreases, the compression spring 18 presses the pressing plate 17 downward, the inclined plate 16 rotates, the fixed box 15 opens, the pressure at the bottom end of the connecting pipe 14 drops, and the pressure tank 13 presses the non-Newtonian fluid inside it out through the connecting pipe 14 into the inside of the fixed box 15. The fluid sprays out, and the sprayed fluid tangles and contacts the broken glass and the workpiece. Under the wrapping of the fluid, the scattering range of the fragments is reduced, the damage range of the flying fragments is reduced, and the safety is improved, solving the problems of poor protection effect of the traditional protection door and easy flying of fragments.

[0020] The heat dissipation mechanism 8 includes an outer cover 20. A speed reduction plate 21 is fixedly connected to the inner surface of the outer cover 20. A water outlet pipe 22 is arranged at the top of the speed reduction plate 21. The bottom end of the water outlet pipe 22 is fixedly connected to the upper surface of the outer cover 20. The top end of the water outlet pipe 22 is fixedly connected to a water tank 23. Heat dissipation fins 24 are fixedly connected to the outer surface of the water tank 23. A water injection pipe 25 is arranged at the top of the heat dissipation fins 24. The bottom end of the water injection pipe 25 is fixedly connected to the upper surface of the water tank 23. The lower surface of the water tank 23 is fixedly connected to a water inlet pipe 26. A return pipe 27 is fixedly connected to the back of the water inlet pipe 26. The left end of the return pipe 27 is fixedly connected to the outer surface of the water tank 23. The right end of the return pipe 27 is fixedly connected to the outer surface of the cabinet body 1. By setting the heat dissipation mechanism 8, when the air intake mechanism 5 cannot meet the heat dissipation requirements of the equipment, the water injection pipe 25 injects cooling water into the water tank 23. The cold water moves from the water inlet pipe 26 to the inside of the outer cover 20. Since the water flow needs to climb over the speed reduction plate 21 one by one to reach the water outlet pipe 22, under the action of the speed reduction plate 21, the water flow velocity decreases, and the residence time of the water flow inside the outer cover 20 is extended. By increasing the heat exchange time, the heat exchange efficiency is increased. The hot water that has completed the heat conversion flows out from the water outlet pipe 22 into the inside of the water tank 23. The return pipe 27 transfers the heat from other areas of the equipment to the water tank 23. The temperature of the water tank 23 rises, and the heat diffuses to the outside through the heat dissipation fins 24. In this way, the equipment uses the internal water circulation of the body to keep the temperature constant, solving the problem that a large amount of external energy is consumed for internal heat dissipation of traditional industrial equipment.

[0021] The air intake mechanism 5 includes an air inlet pipe 30. A filter element 31 is fixedly connected to the bottom end of the air inlet pipe 30. A fixing block 32 is fixedly connected to the inner surface on the right side of the filter element 31. A conical block 33 is arranged on the left side of the fixing block 32. A return spring 34 is fixedly connected to the outer surface on the left side of the conical block 33. The left end of the return spring 34 is fixedly connected to the inner surface of the filter element 31. By setting the air intake mechanism 5, when the equipment is in use, the mechanical and electrical units inside the equipment will release heat outward. Since the inside of the cabinet body 1 is in a sealed state, the heat cannot be dissipated in time. At this time, the air inlet pipe 30 injects cold air into the equipment. Under the push of the air flow, the conical block 33 moves to the left, and the return spring 34 is compressed. The gap between the fixing block 32 and the conical block 33 increases, and air flows in. The filter element 31 filters and purifies the inhaled air to prevent dust from polluting the inside of the equipment. The hot air finally pushes open the cover plate 7 with a part of the heat and discharges from the air outlet groove 6. The air intake mechanism 5 can assist in cooling and also prevent the inside of the equipment from being blocked, solving the problem that the inside of the traditional protective door is easily polluted and blocked by external dust during auxiliary heat dissipation.

[0022] The specific working process is as follows: During operation, the rollers on the upper surface of the protective door 3 rotate, and the inner surface of the protective door 3 slides outward along the outer surface of the sliding rod 2, opening the cabinet body 1. In an artificial or manual manner, an object is placed on the upper surface of the operating table 4. The rollers rotate in the reverse direction, closing the protective door 3. During the movement of the rollers and the sliding rod 2, the speed is stable and the vibration is small. The protective door 3 and the cabinet body 1 will not generate a large friction gap due to vibration. The working condition on the upper surface of the operating table 4 is observed through the observation window 11.

[0023] Since double-layer sealed glass is fixedly installed on both sides of the protective door 3 and the inner layer of the glass is evacuated to a vacuum state, when the protective door 3 is in a normal working state, the outer surfaces on both sides of the inclined plate 16 are in contact with and pressed against the inner surface of the glass, and the outer surface of the inclined plate 16 fits against the inner surface of the fixed box 15. Under the restriction of the compression spring 18, the lower surface of the pressing plate 17 fits against the upper surface of the inclined plate 16. The protection mechanism 12 is in a state of two-force balance under the clamping force of the glass and the downward pressure of the compression spring 18. The fixed box 15 is sealed. When a workpiece inside the cabinet body 1 suddenly flies out, the glass is shattered, and the force balance of the protection mechanism 12 is broken. The external pressure of the inclined plate 16 suddenly decreases, and the compression spring 18 presses the pressing plate 17 downward. The inclined plate 16 rotates, and the fixed box 15 opens. The pressure at the bottom of the connecting pipe 14 drops, and the pressure tank 13 presses the non-Newtonian fluid inside it out through the connecting pipe 14 into the inside of the fixed box 15. The fluid sprays out, and the sprayed fluid tangles and contacts the broken glass and the workpiece. Under the wrapping of the fluid, the scattering range of the fragments is reduced, the damage range of the flying fragments is reduced, and the safety is improved.

[0024] When the equipment is in use, the mechanical and electrical units inside the equipment will release heat outward. Since the inside of the cabinet body 1 is in a sealed state, the heat cannot be dissipated in time. At this time, the intake pipe 30 injects cold air into the equipment. Under the push of the air flow, the conical block 33 moves to the left, and the return spring 34 is compressed. The gap between the fixed block 32 and the conical block 33 increases, and air flows in. The filter element 31 filters and purifies the inhaled air to prevent dust from polluting the inside of the equipment. The hot air finally pushes open the cover plate 7 with a part of the heat and discharges from the air outlet groove 6. The intake mechanism 5 can prevent the inside of the equipment from being blocked while assisting in cooling, solving the problem that the inside of the traditional protective door is easily polluted and blocked by external dust during auxiliary heat dissipation.

[0025] When the air intake mechanism 5 cannot meet the heat dissipation of the equipment, the water injection pipe 25 injects cooling water into the water tank 23, and the cold water moves from the water inlet pipe 26 to the inside of the outer cover 20. Because the water flow needs to cross the deceleration plate 21 one by one to reach the water outlet pipe 22, under the action of the deceleration plate 21, the water flow rate is reduced, and the residence time of the water flow inside the outer cover 20 is prolonged. The heat exchange efficiency is increased by increasing the heat exchange time. The hot water that completes the heat conversion flows out from the water outlet pipe 22 to the inside of the water tank 23. The return pipe 27 transfers the heat from other areas of the equipment to the water tank 23. The temperature of the water tank 23 increases, and the heat is diffused to the outside under the action of the heat sink 24. In this cycle, the equipment uses the water circulation inside the body to maintain a constant temperature.
