Description

Technical Field

[0001] The present invention relates to the technical field of material clamping and handling, and in particular to a material clamping and handling mechanism for intelligent warehousing. Background Art

[0002] The material gripping and handling mechanisms of intelligent warehousing mainly include various automated and intelligent gripping and handling equipment. In the intelligent warehousing system, these material gripping and handling mechanisms are usually combined with warehouse management systems, automatic navigation systems, intelligent information collection and processing systems, etc. to realize the automated management and operation of goods. Through precise positioning, navigation and gripping technology, they can efficiently complete tasks such as handling, storage and sorting of goods, and the mechanism can be selected and applied according to specific warehousing needs. The application of these devices will help improve warehousing efficiency, reduce labor costs, and ensure the accuracy and safety of operations, and promote the continuous development and improvement of intelligent warehousing systems. In some large-scale intelligent warehouses, material clamping and handling mechanisms usually do not require human control and can perform uninterrupted clamping and handling work according to the data provided by the intelligent management system. The shelves of large-scale intelligent warehouses are usually arranged as multi-layer frames. The clamping mechanism usually needs to perform corresponding lifting work during the handling process. The lifting equipment may be worn due to insufficient lubrication when used for a long time, and the wear of the equipment will be aggravated when carrying some heavier goods. When the wear reaches a certain extent, the clamping equipment may fall together with the material, causing damage to the material and even causing some safety accidents.

[0009] Preferably, a wedge-shaped plate is fixedly mounted on the limiting frame via a push rod, and a wedge-shaped column matching the wedge-shaped plate is fixedly mounted on each of the first cylinders via a pull rod.

[0010] Preferably, the magnetic attraction force between the first magnetic plate and the second magnetic plate is greater than the elastic force of the first spring and the elastic rod, and the friction force between the anti-slip pad and the inner wall of the sealing groove is greater than the gravity of the slider.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The present invention utilizes the magnetic attraction of the second magnetic plate to the first magnetic plate, so that the first magnetic plate drives the sliding rod and one end of the two connecting rods to move outside the first limiting groove, and the other ends of the two connecting rods will respectively drive the two clamping blocks to move relative to each other. If the material and the slide plate suddenly fall, the descending speed of the device block will continue to accelerate, and the gas exchange speed in the breathable groove cannot keep up with the descending speed of the slider, which will cause the slider to be subject to resistance and no longer move synchronously with the device block. The first magnetic plate is no longer attracted by the magnetic force of the second magnetic plate. The elastic force of the first spring will cause the two clamping blocks to extend out of the device block and drive the baffle to move downward along the guide strip, so that the telescopic rod is compressed. After the telescopic rod is compressed, the device block, the slide plate and the material will be prevented from continuing to descend, and the telescopic rod will buffer them at the same time, reducing the impact force on the material when it suddenly stops falling.

[0015] The present invention utilizes the weight of the material to make the roller drive the limit frame to overcome the elastic force of the third spring and move downward, and the limit frame will drive the push rod and the wedge plate to move downward synchronously, and through the cooperation of the inclined surface of the wedge plate and the inclined surfaces of the wedge columns on both sides thereof, the wedge columns on both sides will drive the corresponding pull rods and the first cylinder to move relative to each other. The heavier the material, the longer the distance the limit frame drives the wedge plate to descend, and the longer the distance the wedge column drives the first cylinder to move, so that the elastic column is subjected to secondary extrusion, which further increases the clamping force of the material, and the secondary pressure is flexibly adjusted according to the weight of the material itself to prevent the material from being clamped and damaged. At the same time, it can reduce the vibration of the material during the clamping and transportation process to prevent the material from being damaged or falling. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] See also Figure 1-9The present invention provides a technical solution: a material clamping and handling mechanism for intelligent warehousing, comprising a transport vehicle 1, which can automatically and accurately locate and navigate according to the warehouse management system to complete the transportation of materials. A slide rail 2 is fixedly installed on the transport vehicle 1, and a slide plate 3 is slidably installed on the slide rail 2. A plurality of pulleys 46 are rotatably installed on one side of the slide plate 3. Guide rails 5 for limiting the pulleys 46 are arranged on both sides of the slide rail 2. A lifting mechanism 4 for controlling the lifting of the slide plate 3 is fixedly installed on the top of the slide rail 2 (the lifting mechanism 4 is an existing known structure, so the present invention will not be described in detail). By limiting the pulley 46 by the guide rail 5, the lifting mechanism 4 drives the slide plate 3 to slide up and down smoothly on the slide rail 2. The slide plate 3 is symmetrically arranged There are two first cylinders 32, and a second cylinder 33 is fixedly installed at the output end of each first cylinder 32, and a clamping plate 36 for clamping materials is arranged at one end of each second cylinder 33. Two compression grooves 31 are arranged on the slide plate 3, and each first cylinder 32 is slidably installed in the corresponding compression groove 31, and a second spring 37 is fixedly connected to the inner wall of the compression groove 31, and a pressure sensing plate 34 is fixedly installed at the output end of each second cylinder 33, and a plurality of elastic columns 35 are fixedly installed on each pressure sensing plate 34, and each clamping plate 36 is fixedly installed on the corresponding elastic column 35. In the initial state, the first cylinder 32 is pushed by the elastic force of the second spring 37 and is located at the initial end of the compression groove 31. After the transport vehicle 1 moves to the specified position, the first cylinder 32 The second cylinder 33 will extend first, driving the two pressure sensing plates 34 and the clamping plates 36 to move to both sides of the material, and then the first cylinder 32 will extend, causing the clamping plates 36 on both sides to move toward the material, clamp the material, and compress the elastic column 35 to a certain extent. After the pressure sensing plate 34 senses a certain degree of pressure, the first cylinder 32 will stop moving, and then the second cylinder 33 will drive the clamping plates 36 to retract. The clamping force of the clamping plates 36 on the material will cause the material and the clamping plates 36 to retract together. Two support bars 38 for supporting the material are fixedly installed at the bottom of the slide plate 3, and a limit frame 40 is slidably installed in the slide plate 3. A plurality of third springs 41 are fixedly connected between the limit frame 40 and the inner wall of the slide plate 3, and a plurality of rollers 39 are rotatably installed on the limit frame 40. Each roller 39 is located on the corresponding support bar 38, a wedge plate 44 is fixedly installed on the limit frame 40 through a push rod 42, and a wedge column 45 matching the wedge plate 44 is fixedly installed on each first cylinder 32 through a pull rod 43. After the clamping plate 36 drives the material to retract, the material will fall onto the support bar 38 to provide further support for the material. The roller 39 can reduce the friction between the material and the support bar 38. At the same time, the weight of the material will cause the roller 39 to drive the limit frame 40 to overcome the elastic force of the third spring 41 and move downward. The different weights of the materials themselves will cause the limit frame 40 to drop by different distances. When the limit frame 40 drops, it will drive the push rod 42 and the wedge plate 44 to move downward synchronously. Through the cooperation between the inclined surface of the wedge plate 44 and the inclined surfaces of the wedge columns 45 on both sides thereof,The wedge-shaped columns 45 on both sides will drive the corresponding pull rods 43 and the first cylinder 32 to move relative to each other, and the second spring 37 will be compressed. The heavier the material, the longer the distance the limit frame 40 drives the wedge-shaped plate 44 to drop, and the farther the wedge-shaped column 45 drives the first cylinder 32 to move, so that the elastic column 35 is squeezed twice, which further increases the clamping force of the material. The secondary pressure is flexibly adjusted according to the weight of the material itself to prevent the material from being clamped and damaged. At the same time, it can reduce the vibration of the material during the clamping and transportation process to prevent the material from being damaged or falling.

[0020] A guide groove 6 is provided on one side of the slide rail 2, a device block 7 is fixedly installed on one side of the slide plate 3, the device block 7 is slidably installed in the guide groove 6, a first limiting groove 12 and a first slide groove 16 are provided in the device block 7, a first magnetic plate 13 is slidably installed in the first limiting groove 12, two card blocks 17 are slidably installed in the first slide groove 16, a slide rod 14 is fixedly installed at the lower end of the first magnetic plate 13, two connecting rods 15 are rotatably installed at the lower end of the slide rod 14, one end of the two connecting rods 15 is rotatably installed on the two card blocks 17, and the two card blocks 17 are fixedly connected to each other. A first spring 18 is connected, a sealing groove 19 is provided in the slide rail 2, the sealing groove 19 is always in a sealed state in the slide rail 2, a slider 20 is slidably installed in the sealing groove 19, and air-permeable grooves 21 are formed between the two sides of the slider 20 and the inner wall of the sealing groove 19, a plurality of balls 23 are provided on both sides of the slider 20, and a plurality of straight grooves 22 for limiting the balls 23 are provided on the inner walls of both sides of the sealing groove 19, and a second magnetic plate 25 magnetically attracted to the first magnetic plate 13 is provided in each slider 20, and the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the first spring 18. When the lifting mechanism 4 drives the slide plate 3 and the material to move up and down, the device block 7 will also move up and down in the guide groove 6 synchronously. Since the magnetic attraction between the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the first spring 18, under normal conditions, the first magnetic plate 13 will be attracted by the magnetic force of the second magnetic plate 25, and will drive the slide bar 14 and one end of the two connecting rods 15 to move out of the first limiting groove 12. The first slide groove 16 limits the block 17, which will make the two connecting rods 1 The other end of the device block 7 drives the two clamping blocks 17 to move relative to each other and compresses the first spring 18. During the up and down movement of the device block 7, the second magnetic plate 25 drives the slider 20 to move up and down synchronously in the sealing groove 19. The straight groove 22 limits the position of the ball 23, thereby reducing the friction force of the slider 20 when sliding, and ensuring that the air-permeable grooves 21 on both sides of the slider 20 will not change when the slider 20 slides. When the device block 7 drives the slider 20 to slide up and down normally, the air at the upper and lower ends of the slider 20 in the sealing groove 19 is exchanged through the air-permeable grooves 21.

[0021] Several baffles 8 for limiting the block 17 are arranged on the inner walls on both sides of the guide groove 6, several fixed plates 11 are fixedly installed on the inner walls on both sides of the guide groove 6, and a telescopic rod 10 is fixedly installed on each fixed plate 11. Each baffle 8 is fixedly installed at the end of the corresponding telescopic rod 10, and guide strips 9 for limiting the baffle 8 are fixedly installed on the inner walls on both sides of the guide groove 6. If the material, the slide plate 3 and the device block 7 suddenly fall, the descending speed of the device block 7 will continue to accelerate, and the gas exchange speed in the air permeable groove 21 cannot keep up with the descending speed of the slider 20, which will cause the slider 20 to be subjected to resistance , no longer moves synchronously with the device block 7, the first magnetic plate 13 is no longer attracted by the magnetic force of the second magnetic plate 25, and the elastic force of the first spring 18 will cause the two blocks 17 to move in the opposite direction along the first slide groove 16, and the first magnetic plate 13 drives the slide bar 14 to move into the first limit groove 12, and the two blocks 17 will extend out of the device block 7, and drive the baffle 8 to move downward along the guide bar 9, so that the telescopic rod 10 is compressed. After the telescopic rod 10 is compressed, it will prevent the device block 7, the slide plate 3 and the material from continuing to descend, and at the same time, the telescopic rod 10 buffers it, reducing the impact force on the material when it suddenly stops falling.

[0022] A second limiting groove 24 and a second slide groove 27 are provided in the slider 20, the second magnetic plate 25 is slidably installed in the second limiting groove 24, and an elastic rod 26 is fixedly installed between the second limiting groove 24 and the inner wall of the second limiting groove 24, the magnetic attraction between the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the elastic rod 26, and two anti-skid pads 28 for preventing the slider 20 from sliding are slidably installed in the second slide groove 27, the friction force between the anti-skid pads 28 and the inner wall of the sealing groove 19 is greater than the gravity of the slider 20, a wedge block 30 is fixedly installed on one side of the two anti-skid pads 28, a wedge strip 29 matching the wedge block 30 is fixedly installed on one side of the second magnetic plate 25, and a fourth spring 47 is fixedly connected between the two wedge blocks 30, when the first magnetic plate 13 and the second magnetic plate 25 are attracted to each other, because the magnetic attraction between the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the elastic rod 26, the second magnetic plate 25 will overcome the elastic force of the elastic rod 26 and move toward the second limiting groove The second magnetic plate 25 is also located inside the second sliding groove 27, which will not affect the upward and downward movement of the slider 20. When the first magnetic plate 13 is no longer magnetically attracted to the second magnetic plate 25, the second magnetic plate 25 will be driven by the elastic force of the elastic rod 26 to move the wedge strip 29 into the second limiting groove 24. Through the cooperation of the inclined surface of the wedge strip 29 and the inclined surfaces of the wedge blocks 30 on both sides, the wedge blocks 30 on both sides will drive the corresponding anti-skid pads 28 to move outside the second sliding groove 27, and the fourth spring 47 will be stretched, and the two anti-skid pads 28 will contact the inner wall of the sealing groove 19. Since the friction force between the anti-skid pads 28 and the inner wall of the sealing groove 19 is greater than the gravity of the slider 20, the slider 20 will not continue to move downward, preventing the first magnetic plate 13 from being magnetically attracted to the second magnetic plate 25 again during the falling process of the slider 20, resulting in a secondary fall of the slider 3 and the material.

[0023] Specifically, first, the transport vehicle 1 automatically and accurately locates and navigates according to the warehouse management system and drives to the designated position. In the initial state, the first cylinder 32 is pushed by the elastic force of the second spring 37 and is located at the initial end of the compression groove 31. After the transport vehicle 1 moves to the designated position, the second cylinder 33 first extends, driving the two pressure sensing plates 34 and the clamping plate 36 to move to both sides of the material, and then the first cylinder 32 will extend, so that the clamping plates 36 on both sides move toward the material to clamp the material and compress the elastic column 35 to a certain extent. After the pressure sensing plate 34 senses a certain degree of pressure, the first cylinder 32 will stop moving, and then the second cylinder 33 will drive the clamping plate 36 to retract, and the clamping force of the clamping plate 36 on the material will make the material The material retracts together with the clamping plate 36, and the material will fall onto the supporting bar 38 to provide further support for the material. The roller 39 can reduce the friction between the material and the supporting bar 38. At the same time, the weight of the material will cause the roller 39 to drive the limit frame 40 to overcome the elastic force of the third spring 41 and move downward. The different weights of the materials themselves will cause the limit frame 40 to drop by different distances. When the limit frame 40 drops, it will drive the push rod 42 and the wedge plate 44 to move downward synchronously. Through the cooperation of the inclined surface of the wedge plate 44 and the inclined surfaces of the wedge columns 45 on both sides thereof, the wedge columns 45 on both sides will drive the corresponding pull rods 43 and the first cylinder 32 to move relative to each other, and the second spring 37 will be compressed. The heavier the material, the longer the distance that the limit frame 40 drives the wedge plate 44 to drop, and the wedge column 45 drives the third spring 41 to move downward. The farther the cylinder 32 moves, the more the elastic column 35 is squeezed for the second time, which further increases the clamping force on the material, and the secondary pressure is flexibly adjusted according to the weight of the material itself. When the lifting mechanism 4 drives the slide plate 3 and the material to move up and down, the device block 7 will also move up and down in the guide groove 6 synchronously. Since the magnetic attraction between the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the first spring 18, under normal conditions, the first magnetic plate 13 will be attracted by the magnetic force of the second magnetic plate 25, and will drive the slide bar 14 and one end of the two connecting rods 15 to move out of the first limiting groove 12. Through the limitation of the block 17 by the first slide groove 16, the other ends of the two connecting rods 15 will respectively drive the two blocks 17 to move relative to each other, and the first spring 18 will be compressed. During the up and down movement of the device block 7, the second magnetic plate 25 will drive the slider 20 to move up and down synchronously in the sealing groove 19. The straight groove 22 limits the ball 23, which reduces the friction of the slider 20 when it slides, and ensures that the air permeable grooves 21 on both sides of the slider 20 will not change when the slider 20 slides. When the device block 7 drives the slider 20 to slide up and down normally, the air at the upper and lower ends of the slider 20 in the sealing groove 19 is exchanged through the air permeable groove 21. If the material, the slide plate 3 and the device block 7 suddenly fall, the descending speed of the device block 7 will continue to accelerate, and the gas exchange speed in the air permeable groove 21 cannot keep up with the descending speed of the slider 20, which will cause the slider 20 to be subject to resistance and no longer move synchronously with the device block 7. The first magnetic plate 13 is no longer attracted by the magnetic force of the second magnetic plate 25.The elastic force of the first spring 18 will cause the two blocks 17 to move in opposite directions along the first slide groove 16, and cause the first magnetic plate 13 to drive the slide bar 14 to move into the first limiting groove 12. The two blocks 17 will extend out of the device block 7 and drive the baffle plate 8 to move downward along the guide strip 9 to compress the telescopic rod 10. After the telescopic rod 10 is compressed, the device block 7, the slide plate 3 and the material will be prevented from continuing to descend. When the first magnetic plate 13 and the second magnetic plate 25 are attracted to each other, since the magnetic attraction between the first magnetic plate 13 and the second magnetic plate 25 is greater than the elastic force of the elastic rod 26, the second magnetic plate 25 will overcome the elastic force of the elastic rod 26 and move out of the second limiting groove 24. The elastic force of the fourth spring 47 causes the two wedge blocks 30 to move into the second slide groove 27. The two anti-slip pads 28 are also located on the second slide groove. The inside of the groove 27 will not affect the up and down movement of the slider 20. When the first magnetic plate 13 is no longer magnetically attracted to the second magnetic plate 25, the second magnetic plate 25 will be driven by the elastic force of the elastic rod 26 to move the wedge strip 29 into the second limiting groove 24. Through the cooperation of the inclined surface of the wedge strip 29 and the inclined surfaces of the wedge blocks 30 on both sides, the wedge blocks 30 on both sides will drive the corresponding anti-skid pads 28 to move outside the second slide groove 27, and the fourth spring 47 will be stretched. The two anti-skid pads 28 will contact the inner wall of the sealing groove 19. Since the friction between the anti-skid pads 28 and the inner wall of the sealing groove 19 is greater than the gravity of the slider 20, the slider 20 will not continue to move downward, preventing the first magnetic plate 13 from being magnetically attracted to the second magnetic plate 25 again during the falling process of the slider 20, causing the slide plate 3 and the material to fall again.
