Description

Technical Field

[0001] This utility model relates to the field of robotic arm technology, and in particular to a three-axis robotic arm for injection molding material handling. Background Technology

[0002] In food packaging production, a three-axis injection molding robot is an automated device specifically designed for injection molding production lines. It is used to remove molded plastic products from the injection molding machine and place them in a designated location. This type of robot typically has three motion axes (X, Y, and Z axes), enabling precise three-dimensional movement and improving production efficiency and product quality.

[0003] The existing patent number is CN220007836U, which describes a three-axis robotic arm for picking up injection molding rods. This invention relates to the field of robotic arm technology and includes a snare mechanism with a sliding mechanism fixedly installed on its top. In this invention, second rotating shafts are fixedly inserted into the inner walls of both through holes, and two third rotating shafts are fixedly passed through the outer wall of a fixing block. When the first electric telescopic rod moves up and down, the two robotic arms can move through two support rods sleeved on the outer walls of the two second and two third rotating shafts.

[0004] The above solution uses a retrieval tool to retrieve blood bags. The tool is triangular in shape, which helps stabilize the center of gravity of the blood bag, reducing the risk of damage during retrieval. Insufficient gripping can lead to the bag falling during food production, reducing production efficiency. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a three-axis injection molding manipulator, comprising: multiple support rods and a movable block, wherein a vertical rod is fixedly connected to the bottom of the outer surface of the movable block, a disc is fixedly connected to the bottom of the outer surface of the vertical rod, multiple rotating rods are movably embedded inside the disc, and clamping strips are movably sleeved on the outer surface of each of the multiple rotating rods, and two limiting springs are fixedly connected to the outer surface of the opposite side of the multiple clamping strips.

[0006] The technical effect of adopting the above-mentioned further solution is that: by starting the electric push rod two with an external power source, the ring slides downward on the outer surface of multiple clamping strips. At this time, the multiple clamping strips are brought together in the middle by the limit of the rotating rod, thus achieving clamping.

[0007] In a preferred embodiment, two electric push rods are fixedly connected to the bottom of the outer surface of the movable block, and a ring is fixedly connected to the bottom end of each of the two electric push rods. The ring is located on the outer surface of multiple clamping strips.

[0008] The technical effect of adopting the above-mentioned further solution is that multiple clamping bars rotate horizontally in a semi-circle around the disk with the rotating rod as the center. When the ring moves upward, the multiple clamping bars open under the limit of the limiting spring. When the multiple clamping bars move closer to the center, they can clamp the food. The clamping process is more secure and improves the gripping efficiency.

[0009] In a preferred embodiment, a square frame is fixedly connected to the top of the outer surface of the plurality of support rods, and two sliding grooves are formed at the bottom of the outer surface of the square frame. A slider is slidably connected inside each of the two sliding grooves, and a limit rod is fixedly connected to the outer surface of the opposite side of the two sliders.

[0010] The technical effect of adopting the above-mentioned further solution is that the electric push rod is activated by an external power source to push the slider to move inside the slide groove, at which time the slider achieves lateral movement.

[0011] In a preferred embodiment, a reciprocating lead screw is rotatably connected to the outer surfaces of the two sliders on opposite sides via bearings. A motor is fixedly connected to one end of the reciprocating lead screw, and the motor is fixedly connected to the outer surface of one of the sliders. Two electric push rods are fixedly connected to the outer surfaces of both sliders, and both electric push rods are fixedly connected to the outer surface of the frame.

[0012] The technical effect of adopting the above-mentioned further solution is that: the motor is started by an external power source, and the motor drives the reciprocating lead screw to rotate. At this time, under the limit of the limit rod, the moving block slides vertically on its outer surface, and the robot can realize the movement of the X-axis and Y-axis.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In use, this utility model is activated by an external power source, which pushes the electric push rod two to push the ring to slide downward on the outer surface of multiple clamping strips. At this time, the multiple clamping strips are limited by the rotating rod, causing them to move closer to the center. The multiple clamping strips rotate horizontally in a semi-circle around the disc as the center by the rotating rod. When the ring moves upward, the multiple clamping strips open under the limit of the limiting spring. When the multiple clamping strips move closer to the center, they can clamp the food. The clamping process is relatively firm, improving the gripping efficiency.

[0015] 2. In use, the electric push rod is started by an external power source to push the slider to move inside the slide groove. At this time, the slider moves laterally. The motor is started by an external power source, and the motor drives the reciprocating lead screw to rotate. At this time, under the limit of the limit rod, the moving block slides vertically on its outer surface. At this time, the robot can realize the movement of the X-axis and Y-axis.

Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Please see Figures 1 to 4 This utility model provides a three-axis manipulator for injection molding material handling, including: multiple support rods 101 and a moving block 109. A vertical rod 110 is fixedly connected to the bottom of the outer surface of the moving block 109. A disc 112 is fixedly connected to the bottom of the outer surface of the vertical rod 110. Multiple rotating rods 113 are movably embedded inside the disc 112. Clamping strips 114 are movably sleeved on the outer surface of each of the multiple rotating rods 113. Two limiting springs 116 are fixedly connected to the outer surface of the multiple clamping strips 114 on opposite sides. When an electric push rod 111 is activated by an external power source, it pushes a ring 115 to slide downward on the outer surface of the multiple clamping strips 114. At this time, the multiple clamping strips 114 move closer to the center under the limitation of the rotating rods 113, thus achieving clamping.

[0024] like Figures 1 to 4As shown, two electric push rods 111 are fixedly connected to the bottom of the outer surface of the movable block 109. A ring 115 is fixedly connected to the bottom end of each of the two electric push rods 111. The ring 115 is located on the outer surface of multiple clamping strips 114. The multiple clamping strips 114 rotate horizontally in a semi-circle around the disk 112 with the rotating rod 113 as the center. When the ring 115 moves upward, the multiple clamping strips 114 open under the limit of the limiting spring 116. When the multiple clamping strips 114 move closer to the middle, they can clamp the food. The clamping process is more secure and improves the gripping efficiency.

[0025] like Figures 1 to 4 As shown, a square frame 102 is fixedly connected to the top of the outer surface of multiple support rods 101. Two sliding grooves 103 are opened at the bottom of the outer surface of the square frame 102. A slider 105 is slidably connected inside the two sliding grooves 103. A limit rod 106 is fixedly connected to the outer surface of the opposite side of the two sliders 105. When the electric push rod 104 is started by an external power source, the slider 105 is pushed to move inside the sliding groove 103. At this time, the slider 105 moves laterally.

[0026] like Figures 1 to 4 As shown, a reciprocating screw 108 is rotatably connected to the outer surface of the opposite side of the two sliders 105 via bearings. A motor 107 is fixedly connected to one end of the reciprocating screw 108. The motor 107 is fixedly connected to the outer surface of one of the sliders 105. Two electric push rods 104 are fixedly connected to the outer surface of both sliders 105. The two electric push rods 104 are fixedly connected to the outer surface of the frame 102. The motor 107 is started by an external power source, and the motor 107 drives the reciprocating screw 108 to rotate. At this time, under the limit of the limit rod 106, the moving block 109 slides vertically on its outer surface. At this time, the robot can realize the movement of the X-axis and Y-axis.

[0027] Working principle: An external power source activates electric push rod 104, pushing slider 105 to move inside groove 103. Slider 105 moves laterally. An external power source activates motor 107, which drives reciprocating screw 108 to rotate. Limiting by limit rod 106, moving block 109 slides vertically on its outer surface. The robot can then move along the X and Y axes. An external power source activates electric push rod 111, pushing ring 115 through multiple clamping bars 11. The outer surface of 4 slides downward. At this time, the multiple clamping strips 114 are limited by the rotating rod 113, causing the multiple clamping strips 114 to move towards the center. The multiple clamping strips 114 rotate horizontally in a semi-circle around the disk 112 with the rotating rod 113 as the center. At this time, when the ring 115 moves upward, the multiple clamping strips 114 are opened under the limit of the limiting spring 116. When the multiple clamping strips 114 move towards the center, they can clamp the food. The clamping process is more secure and improves the gripping efficiency.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
