[0011] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0012] Please refer to Figure 1-2 , the present utility model provides a technical solution: an automatic nut feeding device, including a machine platform 1 and a material taking jig 5. A vibrating bowl feeder 2 is installed on the machine platform 1, and a horizontal feeding guide rail 4 is installed at the output end of the vibrating bowl feeder 2. Nuts are arranged in an orderly manner in the feeding guide rail 4 and move forward. A support 3 is fixedly installed on the upper surface of the machine platform 1, and a pushing cylinder 7 is fixedly installed on the upper side of the support 3. The pushing cylinder 7 is located at the output port of the feeding guide rail 4 and is perpendicular to the feeding guide rail 4. A discharge port 8 is provided outside the end of the feeding guide rail 4, and the piston rod of the pushing cylinder 7 extends to push the nut out from the discharge port 8.
[0013] The material taking jig 5 includes a square bottom plate 51 and a mounting plate 52. Four cylinders 53 are respectively fixedly installed at the four corners on the front side of the mounting plate 52, and four ejector rods 54 are respectively fixedly installed at the four corners on the front side of the bottom plate 51. The ejector rods 54 are inserted into the cylinders 53 one by one. The front end of the cylinder 53 is docked with the discharge port 8 to accommodate the nut. The material taking jig 5 is driven by a three-axis transfer mechanism. The material taking jig 5 can grab four nuts at a time. The pushing cylinder 7 respectively pushes the nuts into the cylinders 53. The bottom plate 51 is pushed by a telescopic cylinder. When the material taking jig 5 moves to a specific position in the mold, the ejector rod 54 further inserts into the cylinder 53 to push the nut out into the mold. A metal inductor 6 is installed on the machine platform 1. The metal inductor 6 is provided with four horizontally extending detection probes. During detection, the detection probes are inserted into the cylinders 53 one by one. The metal inductor 6 is used to detect whether there is a shortage of nuts in the material taking jig 5. An alarm 9 is installed on the upper side of the machine platform 1, and a control button is installed on the side of the machine platform 1. After the material taking jig 5 grabs the material, the metal inductor 6 detects whether there is a shortage of material. Four nuts are grabbed at a time. If the number of nuts is less than four, a shortage of material is detected, and the alarm 9 gives an audible and visual alarm.
[0014] Working principle: When in use, place this device on one side of the injection molding machine. The material taking fixture 5 is installed on the three-axis transfer mechanism (a mature existing product), so that the material taking fixture 5 can move in space. When the nut is conveyed to the front end of the feeding guide rail 4, the pushing cylinder 7 pushes the nut into the cylinder 53 to achieve grasping. The bottom plate 51 moves forward to eject the nut. After grasping the material, the material taking fixture 5 first goes to the metal inductor 6 for detection to ensure that there is a nut in each cylinder 53.
[0015] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
