Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically, to an automatic unloading device. Background Technology

[0002] like Figure 1 The injection molded part shown includes a main body with a groove. Two injection molded parts are formed at once. After injection molding, the two injection molded parts need to be removed from the mold inserts, and the residual adhesive between the two injection molded parts needs to be removed to form two independent products. Currently, after injection molding, the injection molded parts need to be manually removed from the mold inserts, and the adhesive connecting the two injection molded parts needs to be removed manually with scissors. Whether it is manually removing the injection molded parts from the mold inserts or manually cutting the material, the efficiency is very low and the labor cost is high, which leads to an increase in production costs. Therefore, there is an urgent need for a fixture to replace manual removal of injection molded parts and material removal. Utility Model Content

[0027] Example

[0028] Reference Figure 1-2, Figure 6 As shown, this utility model discloses an automatic unloading device, including a worktable 10 and a robot arm 40. The worktable 10 is provided with a material picking and positioning mechanism 20 and a material unloading mechanism 30. The robot arm 40 is located on one side of the worktable 10 and is equipped with a clamping cylinder for clamping the injection molded part 50. The material picking and positioning mechanism 20 is used to clamp the injection molded part 50 together with the mold insert. The robot arm 40 removes the mold insert and then moves the injection molded part 50 to the material unloading mechanism 30 to remove the rubber material 501 connecting the two injection molded parts 50, thereby realizing automatic unloading to form an independent product.

[0029] Reference Figure 3-4 As shown, the material handling and positioning mechanism 20 includes two first double-headed cylinders 201, and clamping blocks 202 are respectively set on the piston rods at both ends of the first double-headed cylinders 201. Specifically, the robot arm 40 moves the injection molded part 50 with the mold insert onto the first double-headed cylinder 201, controls the first double-headed cylinder 201 to tighten the two clamping blocks 202 to clamp the injection molded part 50, which plays a role in positioning and clamping. After clamping the injection molded part 50, the robot arm 40 is controlled to remove the mold insert from the injection molded part 50, thereby realizing the automated removal of the mold insert.

[0030] Furthermore, a slide rail 203 is installed on the worktable 10 below the first double-headed cylinder 201. A telescopic cylinder 204 is set on one end of the slide rail 203 on the worktable 10. A 7-shaped pressure plate 205 is installed on the slide rail 203. The piston rod of the telescopic cylinder 204 is connected to the pressure plate 205. The pressure plate 205 includes pressure blocks 2051 on both sides. Specifically, after the first double-headed cylinder 201 controls the clamping block 202 to clamp the injection molded part 50, it controls the telescopic cylinder 204 to drive the horizontal part of the pressure plate 205 to move onto the injection molded part 50. The two pressure blocks 2051 press against the injection molded part 50, further pressing and positioning the injection molded part 50, preventing the robot arm 40 from taking away the injection molded part 50 when removing the mold insert from the injection molded part 50.

[0031] Reference Figure 5 As shown, the material removal mechanism 30 includes two fixed second double-headed cylinders 301. A positioning post 302 is set on one side of the middle of the second double-headed cylinder 301, and scissors are installed on the piston rod of the second double-headed cylinder 301. Specifically, pneumatic scissors 303 are installed on the piston rod of the second double-headed cylinder 301. The second double-headed cylinder 301 drives the pneumatic scissors 303 to approach or move away from the positioning post 302. The robot arm 40 picks up the injection molded part 50 from the first double-headed cylinder 201 and moves it to the positioning post 302 for positioning. Then, it controls the second double-headed cylinder 301 to drive the pneumatic scissors 303 to approach the injection molded part 50, and controls the pneumatic scissors 303 to cut off the rubber material 501 connected to the injection molded part 50, thereby realizing automatic material removal.

[0032] Reference Figure 5As shown, the material removal mechanism 30 further includes a notch and a feeding channel provided on the workbench 10. A collection frame 101 is placed at the end of the feeding channel. The rubber material 501 cut off by the pneumatic shears 303 falls from the notch and goes to the collection frame 101 through the feeding channel, so as to avoid the rubber material 501 accumulating on the workbench 10 after falling off and affecting the operation.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
