[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0020] Reference Figure 1-5A loading and unloading mechanism of a four-axis dispensing robot includes a dispensing robot body 1, a dispensing component 11 is movably provided on the dispensing robot body 1, and a movable base 2 is provided on the dispensing robot body 1 below the dispensing component 11; splints 3 are movably provided on both sides of the top of the movable base 2, and a movable plate 5 is connected to the rear of the splint 3 through a first spring 4, and side plates 6 are fixedly provided on both sides of the splint 3 and the movable plate 5.
[0021] Among them, the dispensing robot body 1 is provided with an X-axis, a Y-axis, a Z-axis and a fourth-axis drive assembly, and the X-axis, Y-axis and Z-axis drive assemblies are all moved by slide rails. The robot is controlled to move left and right in the horizontal direction by the X-axis. The robot is controlled to move forward and backward in the horizontal direction perpendicular to the X-axis by the Y-axis. The robot is controlled to move up and down in the vertical direction by the Z-axis. The rotation function is realized by the fourth axis, driving the dispensing assembly 11 to rotate 360 degrees, so that the needle forms an angle with the vertical direction, thereby conveniently applying glue to the inner and outer walls of the object, including surfaces with complex shapes such as circular inner walls, side walls, and corners. It is worth noting that the specific dispensing structure and moving structure of the dispensing robot body 1 and the dispensing assembly 11 are both existing technologies, so they will not be elaborated on.
[0022] In addition, a slide rail is provided at the bottom of the movable base 2, and the movable base 2 moves through the slide rail at its bottom. This is the existing technology, so it will not be described in detail.
[0023] Three first springs 4 are installed behind each side clamping plate 3 , and the other ends of the first springs 4 are connected to the movable plate 5 .
[0024] The bottoms of the side panels 6 are each provided with a guide groove 62, and a guide post 63 is fixedly mounted within each guide groove 62. Guide members 7 are fixedly mounted on both sides of the clamping plate 3 and the movable plate 5, and are guided by the guide posts 63. The provision of the guide posts 63 and the guide members 7 ensures the stability of the clamping plate 3 and the movable plate 5 during movement.
[0025] Therein, adjustment cavities 51 are downwardly opened on both sides of the top of the movable plate 5 , and second springs 52 are upwardly provided at the bottom of the adjustment cavity 51 , and the other ends of the second springs 52 are connected to one end of the limiter 53 .
[0026] Among them, the other end of the limiting member 53 extends out from the adjustment cavity 51, and the top of the side plate 6 is adapted to open a plurality of limiting grooves 61 corresponding to the limiting member 53. Through the adaptation and clamping between the limiting member 53 and the limiting groove 61, the movable plate 5 can be fixed.
[0027] In this embodiment, when dispensing glue on a workpiece, it is only necessary to use one hand to push the two side clamps 3 outwards, and then place the workpiece between the two side clamps 3. At this time, the clamps 3 can be automatically reset and clamped by the elastic force of the first spring 4 behind them, so that the workpiece can be clamped by the two side clamps 3, thereby achieving the clamping of the workpiece. Then, the dispensing of glue on the workpiece can be achieved through the dispensing component 11 on the dispensing robot body 1. After the dispensing of the workpiece is completed, it is only necessary to open the two side clamps 3 again to take out the workpiece. This method of loading and unloading workpieces is very quick and convenient, and is easy for users to use.
[0028] Furthermore, the staff can adjust the position of the movable plates 5 on both sides to adjust the elastic force of the first spring 4, so as to adjust the clamping force of the clamping plates 3 on both sides, thereby ensuring that the clamping mechanism can adapt to workpieces of different sizes.
[0029] When the user needs to adjust the position of the movable panel 5, they only need to pull the limit members 53 on both sides of the movable panel 5 upwards. At this time, the limit members 53 are released from the limit slots 61, and the second springs 52 are stretched. When the user adjusts the movable panel 53 to the appropriate position, they only need to release the limit members 53 on both sides. At this time, the second springs 52 automatically return to their original position due to elastic force, and the limit members 53 can move downward and engage with the other limit slots 61, thereby re-fixing the movable panel 5 and completing the adjustment of the position of the movable panel 5.
[0030] In the utility model, the dispensing of the workpiece can be achieved through the dispensing component 11 on the dispensing robot body 1, and the workpiece can be clamped by setting the clamping plates 3 and the first spring 4 on both sides. This clamping method is quick and convenient to ensure the normal loading and unloading efficiency of the workpiece.
[0031] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
