Description

Technical Field

[0001] This utility model relates to the technical field of injection molding equipment, and in particular to a novel loading and unloading device for punching injection molded parts. Background Technology

[0002] In the field of injection molding production and processing, the punching process is crucial, and the loading and unloading equipment, as a key connecting link, affects the efficiency of the production line. The current market demand is characterized by a variety of products, which puts forward higher requirements for the versatility of equipment. The mainstream robotic arm gripping loading and unloading equipment has problems with adaptability, stability and cost, making it difficult to meet the needs of flexible production.

[0003] Currently, although robotic arm gripping loading and unloading equipment is widely used in standardized production, its gripping stability and safety are insufficient. For injection molded parts with large size differences, especially thin-walled, irregularly shaped or unevenly weighted products, the fixed end effector is difficult to achieve uniform and reliable gripping, which can easily lead to excessive gripping force, causing damage to the injection molded parts and affecting the production quality of the products. Utility Model Content

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: insufficient gripping stability and safety. For injection molded parts with large size differences, especially thin-walled, irregularly shaped, or unevenly weighted products, the fixed end effector is difficult to achieve uniform and reliable gripping, and excessive gripping force can easily damage the injection molded parts, affecting the production quality of the products. Therefore, a new type of loading and unloading equipment for punching injection molded parts is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A novel loading and unloading device for punching injection molded parts includes a multi-axis robotic arm. The end of the multi-axis robotic arm is fixedly mounted with a mounting plate. The mounting plate has horizontally opened moving holes, and moving seats are symmetrically and horizontally slidably mounted in the moving holes. Both movable seats have vertically protruding mounting holes, and each mounting hole contains a straw. A suction cup is fixedly mounted at the lower end of each straw, and the suction cup communicates with the inside of the straw. A rectangular cylinder is fixedly mounted on the mounting plate via a support arm. A connecting pipe is connected to the upper end of each straw, and one end of each connecting pipe is connected to and communicates with the inside of the rectangular cylinder. A piston plate is vertically and slidably mounted inside the rectangular cylinder. An electrically controlled cylinder is fixedly mounted on the support arm via a support rod, and the output end of the electrically controlled cylinder is fixedly connected to the piston plate. The connection point between the connecting pipe and the rectangular cylinder is located below the piston plate.

[0006] Preferably, a lead screw is vertically fixedly installed at the lower end of the rectangular tube, and the lead screw is provided with an adjustment component for driving the two movable seats to move relative to each other.

[0007] Preferably, the adjusting assembly includes a lifting block threaded onto a lead screw, a rotating sleeve block rotatably fitted onto the lifting block, and two support rods rotatably mounted on two movable seats, with the ends of the two support rods furthest from the movable seats rotatably connected to the rotating sleeve block.

[0008] Preferably, a stop block is fixedly installed at the lower end of the lead screw, and the diameter of the stop block is larger than the diameter of the lead screw.

[0009] Preferably, a diversion pipe is fixedly installed on the lower surface of the mounting plate, both ends of the diversion pipe are sealed, and multiple air outlet nozzles are installed obliquely on the side of the diversion pipe.

[0010] Preferably, the upper end of the rectangular cylinder is sealed, and the rectangular cylinder is connected to the diverter pipe via an air pipe, with the connection point between the rectangular cylinder and the air pipe located above the piston plate.

[0011] The beneficial effects of this utility model are as follows: 1. When the piston plate driven by the electric cylinder slides upward inside the rectangular tube, a negative pressure is formed in the space below the piston plate inside the rectangular tube. This negative pressure is transmitted to the suction cup through the connecting pipe and suction pipe, so that the suction cup tightly adheres to the surface of the injection molded part. The atmospheric pressure is used to achieve flexible gripping. The negative pressure adsorption force is evenly applied to the contact surface of the injection molded part. No mechanical clamping force is required, which can avoid damage to thin-walled, irregularly shaped or unevenly weighted injection molded parts due to excessive local force, thus ensuring the production quality of the product. 2. The screw at the lower end of the rectangular tube, in conjunction with the adjusting component, can quickly adjust the distance between the two suction cups, greatly improving the equipment's adaptability to flexible production of multiple varieties and small batches, reducing equipment replacement frequency, and lowering production costs; 3. When the electric cylinder drives the piston plate to reset upward, the gas in the space above the piston plate inside the rectangular cylinder is compressed and transported to the distribution pipe through the air pipe. Then, it is sprayed out by multiple inclined air nozzles. The airflow can directly blow on the surface of the injection molded part to remove residual plastic debris, dust and other impurities.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Reference Figure 1 A novel loading and unloading device for injection molding part punching processing includes a multi-axis robotic arm 1. The end of the multi-axis robotic arm 1 is fixedly mounted with a mounting plate 2. The mounting plate 2 has horizontally opened movable holes, and movable seats 3 are symmetrically and horizontally slidably installed in the movable holes. The multi-axis robotic arm 1 serves as the core of the device's movement and can achieve flexible rotation and movement in multiple directions and angles. This drives the mounting plate 2 and gripping components at the end to precisely connect with the injection molding part storage station and the punching processing station, meeting the loading and unloading position requirements of different production scenarios.

[0016] Reference Figure 2 and Figure 5 Two movable seats 3 are vertically provided with mounting holes, and straws 4 are fixedly installed in both mounting holes. Suction cups 5 are fixedly installed at the lower ends of the two straws 4. The inside of the suction cups 5 is connected to the inside of the straws 4. A rectangular cylinder 6 is fixedly installed on the mounting plate 2 through a support arm. The upper ends of the two straws 4 are connected to connecting pipes 7. One end of the two connecting pipes 7 is connected to the rectangular cylinder 6 and is connected to the inside of the rectangular cylinder 6. A piston plate 8 is vertically and slidably installed inside the rectangular cylinder 6. An electric cylinder 9 is fixedly installed on the support arm through a support rod. The output end of the electric cylinder 9 is fixedly connected to the piston plate 8. The connection between the connecting pipes 7 and the rectangular cylinder 6 is located below the piston plate 8.

[0017] Mounting plate 2 provides a mounting carrier for components such as movable seat 3 and suction tube 4. The movable holes on it provide a horizontal sliding track for movable seat 3, allowing movable seat 3 to adjust the spacing according to the size of the injection molded part. The mounting holes on movable seat 3 are used to fix suction tube 4, ensuring that suction tube 4 is vertical and stable. Suction tube 4 serves as an airflow channel, which can transmit negative pressure to suction cup 5. Suction cup 5 is made of flexible material, which can form a sealed space when in contact with the surface of injection molded part. It firmly fixes injection molded part through negative pressure adsorption force, avoiding damage to injection molded part caused by the rigid clamping force of traditional mechanical gripping. It is especially suitable for thin-walled and irregularly shaped injection molded parts.

[0018] The support arm fixes the rectangular cylinder 6 above the mounting plate 2, ensuring the stability of the rectangular cylinder 6 and not affecting the gripping action below. The rectangular cylinder 6 provides a sealed sliding space for the piston plate 8 and is the core component of the negative pressure of the product. The connecting pipe 7 connects the suction pipe 4 and the rectangular cylinder 6 to form a complete airflow channel, so that the negative pressure in the rectangular cylinder 6 can be transmitted to the two suction cups 5 simultaneously, ensuring uniform adsorption force. The electrically controlled cylinder 9 serves as a power source, and its output shaft extension and retraction can drive the piston plate 8 to slide vertically inside the rectangular cylinder 6. When the output shaft retracts, the piston plate 8 moves upward, the volume of the space below the piston plate 8 in the rectangular cylinder 6 increases, and the air pressure decreases, forming a negative pressure. This negative pressure is transmitted to the suction cups 5 through the connecting pipe 7 and the suction pipe 4 to achieve the adsorption of the injection molded parts. When the output shaft extends, the piston plate 8 returns to its original position downward, the negative pressure disappears, and the suction cups 5 release the injection molded parts, completing the loading and unloading action.

[0019] Reference Figure 4 A screw 10 is vertically fixed at the lower end of a rectangular tube 6. The screw 10 is equipped with an adjustment assembly for driving the two movable seats 3 to move relative to each other. The adjustment assembly includes a lifting block 11 threaded onto the screw 10, a rotating sleeve block 12 rotatably sleeved onto the lifting block 11, and two support rods 13 rotatably mounted on the two movable seats 3 respectively. The ends of the two support rods 13 away from the movable seats 3 are rotatably connected to the rotating sleeve block 12. A stop block 14 is fixedly installed at the lower end of the screw 10. The diameter of the stop block 14 is larger than the diameter of the screw 10.

[0020] The lead screw 10 is vertically fixed to the lower end of the rectangular tube 6, providing a threaded transmission base for the lifting block 11. The adjustment component is used to adjust the distance between the two moving seats 3 to adapt to injection molded parts of different sizes. When the operator rotates the lifting block 11, it will move vertically along the lead screw 10 because the lifting block 11 is threadedly connected to the lead screw 10. When the lifting block 11 rises, it pushes the rotating sleeve block 12 to rise synchronously. The moving seats 3 move closer to each other under the tension of the support rod 13, reducing the distance between the suction cups 5. When the lifting block 11 falls, the rotating sleeve block 12 opens the moving seats 3 to both sides through the support rod 13, increasing the distance between the two suction cups 5 to adapt to large-sized injection molded parts and small-sized injection molded parts. The stop block 14 can prevent the lifting block 11 from falling off the lower end of the lead screw 10, ensuring the stability of the adjustment component structure.

[0021] Reference Figure 3 A diversion pipe 15 is fixedly installed on the lower surface of the mounting plate 2. Both ends of the diversion pipe 15 are sealed. Multiple air nozzles 16 are installed obliquely on the side of the diversion pipe 15. The upper end of the rectangular cylinder 6 is sealed. The rectangular cylinder 6 and the diversion pipe 15 are connected by an air pipe 17. The connection between the rectangular cylinder 6 and the air pipe 17 is located above the piston plate 8.

[0022] The diverter pipe 15 is fixed to the lower surface of the mounting plate 2. Its two ends are sealed to ensure that the airflow is only sprayed from the outlet nozzle 16. Multiple outlet nozzles 16 are set at an angle to accurately guide the airflow to the target area. The air pipe 17 connects the rectangular cylinder 6 and the diverter pipe 15 to form a clean airflow channel. When the electric cylinder 9 drives the piston plate 8 to reset upward, the volume of the space above the piston plate 8 in the rectangular cylinder 6 decreases and the air pressure increases. Compressed air is delivered to the diverter pipe 15 through the air pipe 17 and sprayed out as a directional airflow through the outlet nozzle 16. The airflow can blow away plastic debris, dust and other impurities on the surface of the injection molded part without the need for additional cleaning equipment, thus improving processing efficiency.

[0023] In this invention, when loading and unloading injection molded parts, the multi-axis robotic arm 1 drives two suction cups 5 to move above the injection molded parts and contact the upper surface of the injection molded parts. Then, the electric control cylinder 9 is activated, and its output shaft retracts to drive the piston plate 8 to move upward. The negative pressure of the product in the rectangular cylinder 6 is transmitted to the suction cups 5 through the connecting pipe 7 and the suction pipe 4, adsorbing and fixing the injection molded parts. Then, the multi-axis robotic arm 1 drives the injection molded parts to move, realizing the loading and unloading of injection molded parts. During this process, the suction cups 5 use atmospheric pressure to achieve flexible gripping, and the negative pressure adsorption force is evenly applied to the contact surface of the injection molded parts. No mechanical clamping force is required, which can avoid damage to thin-walled, irregularly shaped, or unevenly weighted injection molded parts due to excessive local force, thus ensuring the production quality of the products.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
