Description

Technical Field

[0001] This utility model relates to the field of preform production technology, specifically to a robotic arm device with a cooling structure. Background Technology

[0002] In the production of bottle preform injection molding, after the bottle preform is injected into the mold, the robot arm needs to accurately reach into the space between the moving mold and the fixed mold to remove the bottle preform. After removal, the bottle preform needs to be cooled outside the mold in time. Otherwise, it will shrink, warp or deform the neck ring due to its own residual heat, resulting in it becoming a defective product. At present, the common cooling methods for bottle preform-specific robots are circulating water cooling or forced air cooling.

[0003] In existing forced air cooling processes, the cooling nozzles are horizontal and the airflow direction is unidirectional. For non-cylindrical preforms such as wide-mouth preforms, the bottle body often has a curved or irregular structure. Simple side blowing cannot make the airflow fit well with the surface of the preform. More cooling dead corners and uneven heat exchange are easily generated in concave or convex parts, which further aggravates the uneven cooling. Utility Model Content

[0004] The purpose of this invention is to provide a robotic arm device with a cooling structure to overcome the shortcomings of the prior art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A robotic arm device with a cooling structure includes a robotic gripper fixed to the robotic arm and a preform body. The right side of the robotic gripper is provided with a negative pressure pipe interface and a cooling air pipe interface. The front side of the robotic gripper is provided with a number of air-cooling components and a number of vacuum adsorption components. Every six air-cooling components are connected to one vacuum adsorption component. The number of preform bodies corresponds to the number of air-cooling components. The preform body is adsorbed by the vacuum adsorption components, and its rear end extends into the interior of the air-cooling components. The negative pressure pipe interface is connected to the interior of all vacuum adsorption components through a pipe. The front side of the robotic gripper is provided with a number of ventilation openings, and each ventilation opening is connected to the rear side of an air-cooling component. Each of the air-cooled components includes a cooling cylinder, the rear side of the preform body is located inside the cooling cylinder, the rear side of the cooling cylinder has several air inlets, the inner wall of the cooling cylinder has several air outlets, each air outlet is connected to several air inlets, the inner wall of the cooling cylinder has an air outlet groove located below the preform body, and all the air outlets are distributed at an angle.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the mechanical gripper has several partitions inside, and each of the ventilation openings is in the shape of two semi-circular arcs, which are symmetrically distributed vertically.

[0008] Furthermore, each of the vacuum adsorption components includes a connecting plate, with a T-shaped mounting block fixedly connected to the rear side of the connecting plate. The front side of the connecting plate has six mounting slots, and there are three T-shaped mounting blocks, which are grouped together with two mounting slots. The rear side of all the T-shaped mounting blocks is connected to a pipe connected to a negative pressure pipe interface. The interior of the connecting plate has six negative pressure slots, which are grouped in pairs. The interior of each T-shaped mounting block is connected to the interior of the upper and lower negative pressure slots. A high-temperature resistant silicone ring is embedded in the interior of all the mounting slots. An adsorption hole penetrating the high-temperature resistant silicone ring is opened in the interior of all the negative pressure slots.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Reference Figures 1-10 As shown, this utility model provides a robotic arm device with a cooling structure, including a robotic gripper 1 fixed to the robotic arm and a preform body 2. The right side of the robotic gripper 1 is provided with a negative pressure pipe interface 3 and a cooling air pipe interface 4. The front side of the robotic gripper 1 is provided with a number of air-cooling components 5 and a number of vacuum adsorption components 6. Every six air-cooling components 5 are connected to one vacuum adsorption component 6. The number of preform bodies 2 corresponds to the number of air-cooling components 5. The preform bodies 2 are adsorbed by the vacuum adsorption components 6 and the rear end extends into the interior of the air-cooling components 5. The negative pressure pipe interface 3 is connected to the interior of all vacuum adsorption components 6 through a pipe. The front side of the robotic gripper 1 is provided with a number of ventilation ports 7, and each ventilation port 7 is connected to the rear side of one air-cooling component 5. Each air-cooled component 5 includes a cooling cylinder 501. The rear side of the preform body 2 is located inside the cooling cylinder 501. Several air inlets 502 are provided on the rear side of the cooling cylinder 501. Several exhaust holes 503 are provided on the inner wall of the cooling cylinder 501. Each exhaust hole 503 is connected to multiple air inlets 502. An exhaust groove 504 is provided on the inner wall of the cooling cylinder 501 located below the preform body 2. All exhaust holes 503 are distributed at an angle. The air inlets 502 and exhaust holes 503 are arranged in a circumferential array.

[0016] The robotic arm drives the robotic gripper 1 to pick up the molded preform body 2. Under the action of the vacuum adsorption component 6, the preform body 2 is removed and initially cooled outside the mold by the built-in air cooling component 5. The operation of the vacuum adsorption component 6 is connected to an external negative pressure machine through the negative pressure pipe interface 3, so that the vacuum adsorption component 6 can work normally. The cooling air pipe interface 4 is connected to an external cold air fan to deliver cold air. After picking up the preform body 2, the preform body 2 located in the cooling cylinder 501 is cooled by the air inlet holes 502 and the air outlet holes 503 arranged in a circumferential array. The inclined setting of the air outlet holes 503 causes the ejected cold air to form a spiral wind belt that rotates at high speed around the preform body 2, which greatly increases the effective flow path of the cold air on the surface of the preform, prolongs the heat exchange time, and improves the cooling efficiency.

[0017] The mechanical gripper 1 has several partition plates 8 inside, and each ventilation opening 7 is in the shape of two semi-circular arcs, which are symmetrically distributed vertically.

[0018] This configuration divides the interior of the mechanical gripper 1 into multiple areas using multiple partitions 8, which facilitates the delivery of cold air to the areas corresponding to the multiple vents, improving the efficiency of cold air delivery. Furthermore, the vents 7 are conveniently positioned to correspond to the air inlets 502 of the cooling cylinder 501, making it easier to deliver cold air.

[0019] Each vacuum adsorption component 6 includes a connecting plate 601, with a T-shaped mounting block 602 fixedly connected to the rear side of the connecting plate 601. The front side of the connecting plate 601 has six mounting slots 603, and there are three T-shaped mounting blocks 602, which are grouped with two mounting slots 603. The rear side of all T-shaped mounting blocks 602 is connected to the pipe connected to the negative pressure pipe interface 3. The interior of the connecting plate 601 has six negative pressure slots 604, which are grouped in pairs. The interior of each T-shaped mounting block 602 is connected to the interior of the upper and lower negative pressure slots 604. A high-temperature resistant silicone ring 605 is embedded in the interior of all mounting slots 603. An adsorption hole 606 penetrating the high-temperature resistant silicone ring 605 is opened in the interior of all negative pressure slots 604. The outer wall of the bottle mouth of the preform body 2 is in contact with the high-temperature resistant silicone ring 605.

[0020] With this configuration, the negative pressure pipe interface 3 is connected to the pipe inside the mechanical gripper 1, so that each T-shaped mounting block 602 has the function of negative pressure extraction pipe, and the interior of the T-shaped mounting block 602 is connected to the negative pressure groove 604 to form a new negative pressure channel. Under the action of the adsorption hole 606, the negative pressure suction work is carried out normally, and under the action of the high temperature resistant silicone ring 605, the preform body 2 can be adsorbed, and then it can be transferred to the next process.

[0021] Each T-shaped mounting block 602 has two mounting grooves 603, a negative pressure groove 604, and a high-temperature resistant silicone ring 605 on its upper and lower sides.

[0022] This design allows each T-shaped mounting block 602 to have a mounting groove 603, a negative pressure groove 604, and a high-temperature resistant silicone ring 605 on both its upper and lower sides, forming a set that can adsorb the two preform bodies 2, reduce the path of the negative pressure channel, and improve the absorption effect.

[0023] The adsorption pores 606 are numerous, with some distributed horizontally and others distributed at an angle.

[0024] This design allows for adsorption not only at the threaded opening of the preform body 2, but also on its outer side. Furthermore, the inner wall of the high-temperature resistant silicone ring 605 adheres to the outer wall of the preform body 2, ensuring that the adsorption force is concentrated there and achieving a vacuum adsorption seal.
