Description

Technical Field

[0001] This utility model relates to the field of plastic product manufacturing technology, specifically to a robotic arm for removing molded products. Background Technology

[0002] Plastic products are a general term for everyday and industrial goods made primarily from plastics. This includes products manufactured using processes such as injection molding and thermoforming. Plastics are a class of malleable synthetic polymers. Together with synthetic rubber and synthetic fibers, they form the three essential synthetic materials for daily life. Currently, plastic products reach a certain temperature after production, making it impossible for workers to directly remove the packaging and counting from the production line; therefore, robotic arms are needed to remove the molded products.

[0003] The existing patent, CN205802457U, entitled "An Automatic Removal Robot for Vacuum-Formed Products," discloses an automatic removal robot for vacuum-formed products. It includes a frame, an X-axis servo mechanism, a Y-axis servo mechanism, an arm, and an arm fixture. The X-axis servo mechanism includes a first mounting frame, a first synchronous belt, a first servo motor, and a first mounting block. The Y-axis servo mechanism includes a second mounting frame, a second synchronous belt, a second servo motor, and a second mounting block. The second mounting frame is mounted on the side of the frame. One side of the first mounting block is fixedly mounted on the first synchronous belt, and one side of the second mounting block is fixedly mounted on the second synchronous belt. The other side of the second mounting block is fixedly connected to the side of the first mounting frame. One end of the arm is fixedly connected to the other side of the first mounting block, and the other end of the arm is fixedly connected to the arm fixture. This invention, through the cooperative structure of the X-axis servo mechanism, the Y-axis servo mechanism, and the arm fixture, delivers the formed products from the processing equipment to the conveyor line for stacking, improving efficiency and ensuring accurate counting.

[0004] The aforementioned device, through the cooperative structure of the X-axis servo mechanism, Y-axis servo mechanism and arm fixture, delivers the formed products from the processing equipment to the conveyor line for stacking, improving efficiency and counting accuracy. However, when gripping products, successful gripping cannot be guaranteed, and errors are prone to occur, leading to errors in subsequent productivity statistics. It cannot adequately meet people's usage needs. In response to the above situation, technological innovation is carried out on the basis of the existing robotic arm. Utility Model Content

[0005] The purpose of this invention is to provide a robotic arm for removing molded products, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a robotic arm for removing molded products, comprising a cantilever and a transfer rail. A lead screw is threadedly connected to the middle of the left side of the cantilever. The transfer rail is slidably connected to the right side of the cantilever, and a sliding rod is installed below the transfer rail. A slider is slidably connected to the periphery of the sliding rod, and a clamping rail is installed below the slider. A moving block is slidably connected inside the clamping rail, and a lead screw is threadedly connected inside the moving block. A clamping assembly is installed below the moving block, and a production line is set below the clamping assembly.

[0007] Furthermore, the clamping assembly includes a clamping plate and a pressure sensor, and a pressure sensor is installed on the outside of the clamping plate. The pressure sensor senses the pressure on the clamping plate and distinguishes whether each set of clamping assemblies has successfully clamped the product.

[0008] Furthermore, a motor is installed on the right side of the lead screw two, and the left and right parts of each section of the lead screw two in the clamping rail have opposite thread directions.

[0009] Furthermore, a rack is installed on the upper right side of the interior of the sliding rail, and a gear meshes on the left side of the rack.

[0010] Furthermore, a motor is installed above the gear. The motor drives the gear to rotate, causing the rack to move back and forth, thereby driving the track to move back and forth.

[0011] Furthermore, guide rods are installed at both ends of the left side of the sliding rail, and the guide rods are slidably connected to the sliding rail.

[0012] Furthermore, a base is installed below the lead screw, and the base is rotatably connected to the lead screw. The motor in the base drives the rotation of the lead screw, thereby driving the cantilever to move up and down on the guide rod.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The motor in the base drives the rotation of the lead screw, thereby driving the cantilever to move up and down on the guide rod. The motor drives the gear to rotate, causing the rack to move back and forth, thereby driving the transfer rail to move back and forth. At the same time, the slider can move back and forth on the slide rod, which facilitates the adjustment of the height and position of the clamping components. The left and right parts of each lead screw in the clamping rail have opposite thread directions. When the motor drives the lead screw to rotate, the two transfer blocks move relative to each other in the clamping rail. The clamping plate clamps the products on the production line. The pressure sensor senses the pressure on the clamping plate and distinguishes whether each set of clamping components has successfully clamped the product, which facilitates the statistics of production volume.

[0014] 1. In this utility model, the left and right parts of each screw rod in the clamping rail have opposite thread directions. When the motor drives the screw rod to rotate, the two moving blocks move relative to each other in the clamping rail. The clamping plate clamps the products on the production line. The pressure sensor senses the pressure on the clamping plate and distinguishes whether each set of clamping components has successfully clamped the product, which is convenient for counting production volume.

[0015] 2. The motor in the base of this utility model drives the rotation of the lead screw, thereby causing the cantilever to move up and down on the guide rod. The motor drives the gear to rotate, causing the rack to move back and forth, thereby driving the transfer rail to move back and forth. At the same time, the slider can move back and forth on the slide rod, which makes it convenient to adjust the height and back and forth position of the gripping component. Moreover, the range of back and forth movement is large, increasing the gripping range. Attached Figure Description

[0020] like Figure 1 and Figure 3As shown, a robotic arm for removing molded products includes a cantilever 1 and a transfer rail 7. A lead screw 2 is threadedly connected to the middle of the left side of the cantilever 1. The transfer rail 7 is slidably connected to the right side of the cantilever 1, and a slide rod 9 is installed below the transfer rail 7. A slider 10 is slidably connected to the periphery of the slide rod 9, and a gripping rail 11 is installed below the slider 10. A moving block 12 is slidably connected inside the gripping rail 11, and a lead screw 13 is threadedly connected inside the moving block 12. A gripping assembly 15 is installed below the moving block 12, and a production line is located below the gripping assembly 15. Line 16, the clamping assembly 15 includes a clamping plate 1501 and a pressure sensor 1502, and the pressure sensor 1502 is installed on the outside of the clamping plate 1501. The left and right parts of each lead screw 13 in the clamping rail 11 have opposite thread directions. When the motor 14 drives the lead screw 13 to rotate, the two moving blocks 12 move relative to each other in the clamping rail 11. The clamping plate 1501 clamps the product on the production line 16. The pressure sensor 1502 senses the pressure on the clamping plate 1501 and distinguishes whether each set of clamping assemblies 15 has successfully clamped the product, which is convenient for counting production volume.

[0021] like Figure 1 and Figure 2 As shown, a motor 14 is installed on the right side of the lead screw 13. A rack 8 is installed on the upper right side of the inside of the sliding rail 7, and a gear 6 meshes with the left side of the rack 8. A motor 5 is installed above the gear 6. Guide rods 3 are installed at the front and rear ends of the left side of the inside of the sliding rail 7, and the guide rods 3 are slidably connected to the sliding rail 7. A base 4 is installed below the lead screw 2, and the base 4 is rotatably connected to the lead screw 2. The motor in the base 4 drives the rotation of the lead screw 2, thereby driving the cantilever 1 to move up and down on the guide rod 3. The motor 5 drives the rotation of the gear 6 to move the rack 8 back and forth, thereby driving the sliding rail 7 to move back and forth. At the same time, the slider 10 can move back and forth on the slider 9, which facilitates the adjustment of the height and back and forth position of the gripping component 15, and the range of back and forth movement is large, increasing the gripping range.

[0022] Working principle: When using this type of manipulator to remove molded products, firstly, the motor in the base 4 drives the rotation of the lead screw 2, thereby causing the cantilever 1 to move up and down on the guide rod 3. The motor 5 drives the gear 6 to rotate, causing the rack 8 to move back and forth, thereby driving the transfer rail 7 to move back and forth. At the same time, the slider 10 can move back and forth on the slide rod 9, which facilitates the adjustment of the height and back and forth position of the gripping assembly 15. The range of back and forth movement is large, increasing the gripping range. The left and right parts of each lead screw 13 in the gripping rail 11 have opposite thread directions. When the motor 14 drives the lead screw 13 to rotate, the two transfer blocks 12 move relative to each other in the gripping rail 11. The clamping plate 1501 clamps the product on the production line 16. The pressure sensor 1502 senses the pressure on the clamping plate 1501 and distinguishes whether each set of gripping assemblies 15 has successfully gripped the product, which is convenient for counting production volume.
