[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0019] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0020] Figure 1-Figure 3This is a specific embodiment of the utility model, which is an automatic epoxy resin loading device for a TO-220 packaged transistor injection molding machine. The workbench 1 is a rectangular platform, and a loading circular vibration plate 2 is installed on the left rear thereof. A loading tray 4 is arranged on the right side of the loading circular vibration plate 2, and a loading circular vibration plate guide rail 3 is arranged between the loading tray 4 and the loading circular vibration plate 2. An injection molding machine epoxy resin cake ball rack 5 is placed in the loading tray 4. The loading tray 4 is connected to the rotating motor 9 through the loading tray rotating bracket 8. A residual material recovery circular vibration plate 11 is connected to the front side of the loading circular vibration plate 2 through the residual material recovery circular vibration plate guide rail 12. A residual material recovery material guide box 10 is arranged on the right side of the residual material recovery circular vibration plate 11. The rotation of the rotating motor 9 can drive the loading tray 4 to move above the residual material recovery material guide box 10.
[0021] The loading tray 4 includes a support platform 401, a support bucket 402 is hinged on one side of the support platform 401, and a lifting rod 403 is connected between the bottom of the other side of the support platform 401 and the support platform 401. An epoxy resin cake ball rack 5 for injection molding machine is placed in the support bucket 402, and a filling round hole 501 is opened on the epoxy resin cake ball rack 5 for injection molding machine. A fine hole is opened at the position corresponding to the filling round hole 501 on the support bucket 402, and an air pipe 6 is connected to the bottom of the fine hole, and an air pump 7 is connected to the end of the air pipe 6. A micro-vibration motor is installed on the support bucket 402. When the rotating motor 9 drives the loading tray 4 to move above the residual material recovery guide box 10, the lifting rod 403 contracts to make the support bucket 402 flat, so that the residual material in the support bucket 402 can enter the residual material recovery guide box 10.
[0022] The specific usage of this embodiment is as follows:
[0023] Turn on the machine and adjust the speed of the vibrating disc to pour the plastic sealing material (epoxy resin) into the vibrating disc, which enters the loading tray through the track. The machine will automatically stop when the amount is sufficient, and then it will leak into the filling circular hole of the epoxy resin cake ball rack of the injection molding machine. There is a slight vibration at the bottom, which can make the plastic sealing material enter the hole more smoothly. The tray at the bottom has suction through the air pump to temporarily fix the plastic sealing material in the rack. After it is full, take out the frame filled with plastic sealing material and enter the next step. The residual material is driven by the rotation of the motor to rotate the tray to the residual material recovery guide box. The tray is laid flat and falls out under vibration, and finally enters the residual material recovery circular vibration disc, and then is introduced into the feeding circular vibration disc to form a residual material circulation.
[0024] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
