DETAILED DESCRIPTION

[0023] The following describes the embodiments of the present invention through specific examples. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. The details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other unless they conflict.

[0024] Example:

[0025] Please refer to Figure 1-5 , an automatic feeding and unloading machine manipulator for an injection molding machine includes a connecting column 102 and a mechanical gripper 201;

[0026] Connecting column 102, the bottom end of the connecting column 102 is connected to the base 1, and a motor 101 is provided in the base 1. The motor 101 is rotatably connected to the connecting column 102 through the output end. A support rod 103 is fixed to the top of the connecting column 102, and a telescopic cylinder 104 is fixed to one end of the support rod 103. The bottom end of the telescopic cylinder 104 is connected to the connecting block 2 through the output end. Mechanical grippers 201 are provided on the four outer walls of the connecting block 2. By starting the motor 101 and driving the connecting column 102 to rotate above the base 1 through the output end, the connecting column 102 can be easily adjusted in position by driving the mechanical gripper 201 through the support rod 103 and the telescopic cylinder 104. Then, the telescopic cylinder 104 is started to allow the output end to drive the mechanical gripper 201 to move up and down through the connecting block 2, so that the mechanical gripper 201 can easily clamp the finished product.

[0027] A driving mechanism is provided in the connecting block 2, which drives the mechanical gripper 201 to rotate. A first connecting groove 202 is provided on the inner wall of the mechanical gripper 201. Slide bars 203 are provided on both sides of the inner wall of the first connecting groove 202. Each slide bar 203 is sleeved with a first spring 204 and a connecting frame 205. One end of the first spring 204 is fixed to the inner wall of the first connecting groove 202, and the other end of the first spring 204 is fixed to the connecting frame 205. A touch block 206 is fixed to one end of the connecting frame 205. A plurality of resistance bars 207 are provided on one side of the touch block 206. Each resistance bar 207 is inclined. The resistance bar 207 is set to be a rubber resistance bar 207. When encountering a solid finished product, the driving mechanism drives the mechanical gripper 201 to clamp the finished product. When the mechanical gripper 201 clamps the outer wall of the finished product, the resistance bar 207 will drive the connecting frame 205 to slide outside the slide rod 203 through the touch block 206, and then drive the connecting frame 205 to move through the elastic force of the first spring 204, so that the touch block 206 drives the resistance bar 207 to be close to the outer wall of the finished product. The rubber material and inclined setting of the resistance bar 207 increase the resistance of the outer wall of the finished product, so that the finished product will not be separated from the mechanical gripper 201.

[0028] The outer wall of the mechanical gripper 201 is provided with a second connecting groove 208, and the inner wall of the second connecting groove 208 is rotatably connected to a rotating rod 209, and a support plate 210 is fixed to the outside of the rotating rod 209. Both ends of one side of the support plate 210 are connected to a second spring 211, and one end of the second spring 211 is fixed to the inner wall of the second connecting groove 208. The other side of the support plate 210 is connected to a connecting rod 212, and one end of the connecting rod 212 is movably connected to a roller 213, and one end of the roller 213 is connected to a baffle 214. One end of the baffle 214 is movably connected to a connecting shaft 216, and the connecting shaft 216 is fixedly connected to the outer wall of the mechanical claw, and the other end of the baffle 214 is fixedly connected to a connecting rod for limiting the roller 21 3, when encountering a solid finished product, the mechanical gripper 201 is started through the connecting block 2 to grab the finished product, so that one end of the baffle 214 is connected to the inner wall of the finished product, so that the baffle 214 is rotated through the connecting shaft 216, and one side of the baffle 214 is moved against the roller 213, and the connecting rod 212 drives one end of the support plate 210 to rotate, and then the elastic force of the second spring 211 drives the support plate 210 to rotate, so that the connecting rod 212 and the pulley are against the baffle 214, so that the baffle 214 can be tightly attached to the inner wall of the finished product, so that the finished product will not fall off when clamped, and the roller 213 is prevented from completely separating from one side of the baffle 214 by the connecting plate 214.

[0029] A screen is provided on the bottom surface of the inner wall of the connecting block 2, and a fan is provided on the top surface of the screen. When the mechanical gripper 201 clamps the finished product, the fan is started to allow wind to pass through the screen to cool the finished product, preventing the staff from getting burned when touching the finished product, and the screen is used to prevent external dust from clogging the fan.

[0030] Working principle: The device first starts the motor 101 and drives the connecting column 102 to rotate above the base 1 through the output end, so that the connecting column 102 can easily drive the mechanical gripper 201 to adjust its position through the support rod 103 and the telescopic cylinder 104, and then starts the telescopic cylinder 104 to allow the output end to drive the mechanical gripper 201 to move up and down through the connecting block 2, so that the mechanical gripper 201 can easily clamp the finished product. When encountering a solid finished product, the mechanical gripper 201 is driven by the driving mechanism to clamp the finished product. When the mechanical gripper 201 is clamping the outer wall of the finished product, the resistance bar 207 will drive the connecting frame 205 to slide outside the slide bar 203 through the touch block 206, and then the elastic force of the first spring 204 drives the connecting frame 205 to move, so that the touch block 206 drives the resistance bar 207 to stick to the outer wall of the finished product, and the rubber material and inclined setting of the resistance bar 207 are used to increase the resistance of the outer wall of the finished product, so that the finished product will not separate from the mechanical gripper 201. When a solid finished product is encountered, the mechanical gripper 201 is started by the connecting block 2 to grab the finished product, so that one end of the baffle 214 is connected to the inner wall of the finished product, so that the baffle 214 is rotated through the connecting shaft 216, so that one side of the baffle 214 pushes against the roller 213 to move, and the connecting rod 212 drives one end of the support plate 210 to rotate, and then the elastic force of the second spring 211 drives the support plate 210 to rotate, so that the connecting rod 212 and the pulley push against the baffle 214, so that the baffle 214 can be tightly attached to the inner wall of the finished product, so that the finished product will not fall off when clamped, and the connecting plate 215 prevents the roller 213 from completely separating from one side of the baffle 214. Finally, when the mechanical gripper 201 clamps the finished product, the fan 218 is started to let the wind pass through the screen 217 to cool the finished product, so as to prevent the staff from being scalded when touching the finished product, and the screen 217 is used to prevent external dust from clogging the fan 218.

[0032] The above embodiments merely represent specific implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention.
