[0026] The following will be combined with the accompanying 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 8 As shown, a safety protection device for a loading and unloading robot comprises a robot arm 1; a power control box 11 is connected to the bottom of the robot arm 1; a first support column 12 is fixedly connected to the bottom of the power control box 11; a base 13 is fixedly connected to the bottom of the first support column 12; a plurality of groups of inclined columns 14 are fixedly connected to the middle of the base 13; the ends of the inclined columns 14 are fixedly connected to a connecting plate 15; a rotating shaft 16 is rotatably connected to the middle of the connecting plate 15; a gear 17 is fixedly connected to the end of the rotating shaft 16; a hollow disc 18 is fixedly connected to the middle of the connecting plate 15; the hollow disc A circular rack 19 is connected to the middle of the disk 18; a plurality of rack plates 111 are slidably connected to the middle of the circular rack 19; a plurality of connecting columns 112 are fixed to the middle of the rack plate 111; an arc plate 113 is fixed to the end of the connecting column 112; a plurality of intercepting columns 114 are fixed to one side of the arc plate 113; a servo motor 115 is connected to the end of the rotating shaft 16; when the robot arm 1 is working, the servo motor 115 can be started first and thereby drive the rotating shaft 16 to rotate in the middle of the connecting plate 15, and the rotation of the rotating shaft 16 will drive The gear 17 rotates, and when the gear 17 rotates, it drives the circular rack 19 to rotate in the middle of the hollow disc 18. At the same time, when the gear 17 rotates, it also drives the rack plate 111 to slide in the middle of the hollow disc 18. At this time, the connecting column 112 moves with the sliding of the rack plate 111, and the connecting column 112 drives the arc plate 113 and the intercepting column 114 to extend to the surrounding areas. This step can isolate the area where the robot arm 1 is working by opening the arc plate 113 and the intercepting column 114, thereby warning people. Personnel should pay attention to avoid it to prevent them from accidentally entering the working area of the robot arm 1 and causing accidental collision with the robot arm 1 and causing injury. The servo motor 115 drives the rack plate 111 to extend the arc plate 113, so as to prevent the robot arm 1 from moving in different ranges due to different operations. When the moving range of the robot arm 1 is too large, it will be difficult for the arc plate 113 to isolate the working area of the robot arm 1 well, so that people may accidentally enter the working range of the robot arm 1 and be injured.

[0028] like Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 、 Figure 8As shown, the middle part of the power control box 11 is slidably connected with a groove column 2; a plurality of support plates 21 are fixedly connected to the middle part of the power control box 11; a sliding column 22 is slidably connected to the middle part of each support plate 21; the end of the sliding column 22 is fixedly connected to a triangular clamping plate 24; a tension spring 23 is connected to the middle part of the triangular clamping plate 24; a power-off button 25 is connected to the middle part of the power control box 11; when working, the tension spring 23 can push the triangular clamping plate 24 to clamp the groove column 2. When the robot arm 1 fails, it can press the end of the groove column 2 and make the groove column 2 slide toward the inside of the power control box 11. When the groove column 2 slides, the triangular clamping plate 24 is subjected to pressure, which will drive the sliding column 22 to slide in the middle of the support plate 21, and when the triangular clamping plate 24 slides, the tension spring 23 will also Under the action of pressure, it retracts, so that the groove column 2 can slide smoothly into the power control box 11 until its end squeezes the power-off button 25 to cut off the power to the robot arm 1. This step presses the groove column 2 and presses the power-off button 25 to cut off the power to the robot arm 1, so that the robot arm 1 can stop working when a failure occurs, thereby preventing the failure from easily causing further damage to the robot arm 1 or performance degradation, and can also reduce further expansion of losses. The triangular clamping plate 24 can form a certain clamping effect on the groove column 2, thereby preventing the staff from causing the groove column 2 to slide down due to a slight touch, so that the power-off button 25 is squeezed to cause the robot arm 1 to cut off the power.

[0029] like Figure 6 、 Figure 8 As shown, multiple sets of guide rails 3 are connected to the middle of the power control box 11; the bottom of the triangular clamping plate 24 is fixedly connected to a horizontal axis 31; the middle of the horizontal axis 31 is rotatably connected to a groove roller 32; during operation, when the triangular clamping plate 24 slides under the action of pressure, because the groove roller 32 is in contact with the surface of the power control box 11, it will generate friction with the surface of the power control box 11 under the movement of the triangular clamping plate 24, and then roll in the middle of the horizontal axis 31, and the groove roller 32 will always move horizontally and linearly under the action of the guide rail 3 when rolling. This step can limit the moving trajectory of the groove roller 32 through the cooperation of the groove roller 32 and the guide rail 3, thereby preventing the groove roller 32 from easily deviating during movement, which may affect the clamping effect of the triangular clamping plate 24 on the groove column 2.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown, the rack plate 111 is provided with a slide groove 4 in the middle part; the hollow disc 18 is fixed with multiple groups of slide grooves 4 in the middle part; the end of the slide groove 4 is connected to the middle part of the slide groove 4; during operation, under the action of the connection relationship between the limit plate 41 and the slide groove 4, when the rack plate 111 slides in the middle part of the hollow disc 18, the rack plate 111 will be restricted by the slide groove 4 and the limit plate 41 to slide. This step can prevent the rack plate 111 from easily deviating to the left and right when sliding, or even sliding out of the middle part of the hollow disc 18, thereby causing the arc plate 113 to fall off, resulting in the arc plate 113 affecting the isolation of the working area of the robot arm 1.

[0031] like Figure 1 、 Figure 2 、 Figure 4 As shown, a fastening ring 5 is fixed to the middle of the servo motor 115; a plurality of second support columns 51 are fixed to the middle of the fastening ring 5; the ends of the second support columns 51 are fixed to the bottom of the connecting plate 15; when working, the servo motor 115 will produce a certain degree of vibration. At this time, the frequency of the vibration of the servo motor 115 can be reduced under the action of the fastening ring 5 and the second support column 51. This step can prevent the situation where the vibration frequency of the servo motor 115 is too large, thereby affecting the normal rotation of the rotating shaft 16, through the action of the fastening ring 5 and the second support column 51, and the fastening ring 5 and the second support column 51 can also fix the servo motor 115, thereby enhancing the connection stability between the servo motor 115 and the connecting plate 15.

[0032] like Figure 8 As shown, the power-off button 25 is connected with a beeswax layer 6 on all sides; during operation, when the end of the groove column 2 squeezes the power-off button 25, it will first squeeze the beeswax layer 6. At this time, the beeswax layer 6 will be broken by the pressure, thereby exposing the power-off button 25 to the outside world, so that the end of the groove column 2 can smoothly squeeze the power-off button 25 and cut off the power to the robot arm 1. This step can protect the power-off button 25 through the opening of the beeswax layer 6, thereby increasing a certain resistance to squeezing the power-off button 25, thereby preventing the power-off button 25 from being squeezed when a person accidentally touches the groove column 2, thereby causing the robot arm 1 to be powered off.

[0033] like Figure 1 、 Figure 2 、 Figure 7 、 Figure 8As shown, the end of the groove column 2 is fixedly connected to the limiting pad 7; during operation, when the groove column 2 is pressed, the limiting pad 7 will slide as the groove column 2 slides. When the end of the groove column 2 slides to the power control box 11, the limiting pad 7 can limit the groove column 2 from continuing to slide. This step, through the action of the limiting pad 7, can prevent the groove column 2 from being completely immersed in the power control box 11 due to excessive pressing force when sliding, thereby making it difficult to remove the groove column 2.

[0034] Working principle, when the robot arm 1 is working, the servo motor 115 can be operated first and thereby drive the rotating shaft 16 to rotate in the middle of the connecting plate 15. The rotation of the rotating shaft 16 will drive the gear 17 to rotate. When the gear 17 rotates, it will drive the circular rack 19 to rotate in the middle of the hollow disc 18. At the same time, when the gear 17 rotates, it will also drive the rack plate 111 to slide in the middle of the hollow disc 18. At this time, the connecting column 112 will move with the sliding of the rack plate 111, and the connecting column 112 will drive the arc plate 113 and the intercepting column 114 to extend to the surrounding areas when it moves. This step can adjust the working area of the robot arm 1 by opening the arc plate 113 and the intercepting column 114. Isolation is performed, thereby warning personnel to avoid it and preventing personnel from mistakenly entering the working area of the robot arm 1 and causing accidental collision with the robot arm 1 and causing injury. The servo motor 115 drives the rack plate 111 to extend the arc plate 113, so as to prevent the robot arm 1 from moving in different ranges due to different operations. When the robot arm 1 moves in a large range, the arc plate 113 will not be able to isolate the working area of the robot arm 1 well, so that personnel may mistakenly enter the working range of the robot arm 1 and be injured. When working, the tension spring 23 can push the triangular clamping plate 24 to clamp the groove column 2, and when the robot arm 1 fails, the end of the groove column 2 can be pressed. The groove column 2 is made to slide toward the inside of the power control box 11. When the groove column 2 slides, the triangular clamping plate 24 is under pressure to drive the sliding column 22 to slide in the middle of the support plate 21, and when the triangular clamping plate 24 slides, the tension spring 23 is also retracted under pressure, so that the groove column 2 can slide smoothly toward the inside of the power control box 11 until its end squeezes the power-off button 25 to cut off the power to the robot arm 1. This step cuts off the power to the robot arm 1 by pressing the groove column 2 and pressing the power-off button 25, so that the robot arm 1 can stop working when a fault occurs, thereby preventing the fault from easily causing further damage or performance degradation of the robot arm 1, and can also reduce In order to reduce the further expansion of the loss, the triangular clamping plate 24 can form a certain clamping effect on the groove column 2, thereby preventing the staff from sliding down due to a slight touch, so as to prevent the power-off button 25 from being squeezed and causing the robot arm 1 to be powered off. During operation, when the triangular clamping plate 24 slides under the action of pressure, the groove roller 32 is in contact with the surface of the power control box 11. At this time, it will generate friction with the surface of the power control box 11 under the movement of the triangular clamping plate 24, and then roll in the middle of the horizontal axis 31. When the groove roller 32 rolls, it will be affected by the guide rail 3 and will always move horizontally and linearly. This step can limit the moving trajectory of the groove roller 32 through the cooperation of the groove roller 32 and the guide rail 3.The groove roller 32 is prevented from being easily deflected when it moves, which may affect the clamping effect of the triangular clamping plate 24 on the groove column 2. When working, under the action of the connection between the limit plate 41 and the slide 4, when the rack plate 111 slides in the middle of the hollow disc 18, the rack plate 111 will be restricted by the slide 4 and the limit plate 41 to slide. This step is to prevent the rack plate 111 from easily deflecting left and right when sliding, or even sliding out of the middle of the hollow disc 18, by providing the slide 4 and the limit plate 41. The arc plate 113 falls off, causing the arc plate 113 to affect the isolation of the working area of the robot arm 1. When working, the servo motor 115 will produce a certain vibration. At this time, the frequency of the servo motor 115 vibration can be reduced under the action of the fastening ring 5 and the second support column 51. This step can prevent the servo motor 115 from vibrating too much, thereby affecting the normal rotation of the shaft 16, and the fastening ring 5 and the second support column 51 can also prevent the servo motor 115 from vibrating too much. 15 plays a fixing role, strengthening the connection stability between the servo motor 115 and the connecting plate 15. During operation, when the end of the groove column 2 squeezes the power-off button 25, it will first squeeze the wax layer 6. At this time, the wax layer 6 will be broken by the pressure, thereby exposing the power-off button 25 to the outside world, so that the end of the groove column 2 can smoothly squeeze the power-off button 25 and cut off the power to the robot arm 1. This step can protect the power-off button 25 through the opening of the wax layer 6, thereby increasing a certain resistance to squeezing the power-off button 25, thereby preventing If a person accidentally touches the groove column 2, it is easy to squeeze the power-off button 25, causing the robot arm 1 to lose power. During operation, when the groove column 2 is pressed, the limit pad 7 will slide with the sliding of the groove column 2. When the end of the groove column 2 slides to the power control box 11, the limit pad 7 can limit the groove column 2 from continuing to slide. This step, through the function of the limit pad 7, can prevent the groove column 2 from being completely immersed in the power control box 11 due to excessive pressing force when sliding, making it difficult to remove the groove column 2.
