Description

Technical Field

[0001] This utility model relates to the field of molded product loading and unloading technology, and in particular to an automated molded product loading and unloading device. Background Technology

[0002] A molding machine is a mechanical device that uses a mold to apply pressure, causing materials such as metal, plastic, and rubber to deform or solidify, forming products of a specific shape. The loading and unloading of molded products are automated through robotic arms and suction cups. During loading, the robotic arm moves the material into the molding machine through the suction cups. After the material is processed, it is removed through the suction cups at the end of the robotic arm.

[0003] After prolonged use, the gears inside the base of the robotic arm generate heat due to friction. This heat causes the viscosity of the lubricating oil inside the base to decrease, making it impossible to form a sufficiently thick oil film on the gear contact surface, thus weakening the lubrication effect. Therefore, this application provides an automated molded product loading and unloading device to meet this need. Utility Model Content

[0004] This invention provides an automated loading and unloading device for molded products to solve the problem that lubricating oil viscosity decreases after heating, making it unable to form a sufficiently thick oil film on the gear contact surface, thus weakening the lubrication effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An automated molding product loading and unloading device includes a robotic arm, the output end of which is equipped with a suction cup, and further includes: A cooling mechanism for cooling the lubricating oil inside the base of the robotic arm.

[0006] Preferably, the cooling mechanism includes a housing fixed to the side of the robotic arm base. A circulation pump is fixed to the top of the housing, and the output end of the circulation pump is connected to the top of the housing. The input end of the circulation pump is connected to the oil outlet of the robotic arm through a pipe. An oil delivery pump is fixed to the bottom of the housing. The oil delivery pump inlet is connected to the bottom of the housing through a round pipe. The oil delivery pump outlet is connected to the oil inlet of the robotic arm through a pipe. An inverted V-shaped plate is fixed to the inner wall of the housing. Two symmetrically arranged heat dissipation plates are fixed to the inner wall of the housing and below the inverted V-shaped plate. A sealing plate is fixed to the bottom of the heat dissipation plate. The side of the sealing plate is fixedly connected to the inner wall of the housing. A fan is fixed at a round hole on the side of the housing. An air outlet is opened on the side of the housing.

[0007] Preferably, a bracket is fixed to the surface of the housing, and the bracket is fixed to the base of the robotic arm by bolts.

[0008] Preferably, the heat sink is wavy.

[0009] Preferably, a plurality of fins are fixed on opposite sides of the heat sink.

[0010] Preferably, a number of baffles are fixed vertically and horizontally on opposite sides of the heat sink. One end of the baffle is fixed to the inner wall of the housing, and a flow channel is formed between the other end of the baffle and the inner wall of the housing. The flow channels of adjacent baffle ends are staggered.

[0011] Preferably, the inner wall of the baffle is hollow, and a strip-shaped hole is provided at the end of the baffle. A strip-shaped hole is provided on the surface of the heat sink, and the strip-shaped hole is connected to the strip-shaped hole.

[0012] Preferably, the end of the baffle is provided with a square hole one, and the surface of the housing is provided with a square hole two, with the square hole one and the square hole two communicating with each other.

[0013] Compared with the prior art, this utility model has at least the following beneficial effects: In the above solution, by setting up a cooling mechanism, the lubricating oil in the base of the robotic arm can be cooled, avoiding the decrease in viscosity caused by excessively high lubricating oil temperature, and ensuring that the lubricating oil can form a sufficiently thick oil film on the gear contact surface, thereby ensuring the lubrication effect.

[0014] By incorporating a housing, a circulating pump, an inverted V-shaped plate, a heat sink, and a fan, the system works as follows: during heat dissipation, the circulating pump and pipe one draws lubricating oil from inside the robotic arm and discharges it from the top of the housing. Upon contact with the inverted V-shaped plate, the lubricating oil is split to both sides, flowing onto the surface of the heat sink. The heat from the lubricating oil is transferred to the heat sink. Simultaneously, the fan starts, and the airflow from the fan dissipates heat from the heat sink. The airflow then exits through the vent, thus cooling the lubricating oil. The cooled lubricating oil flows to the bottom of the housing and is then transported back to the base of the robotic arm via an oil pump and pipe two. This continuous circulation process continuously cools the lubricating oil in the robotic arm base, improving the cooling effect. Furthermore, the wavy shape of the heat sink slows the flow rate of the lubricating oil on its surface, increasing the contact time between the lubricating oil and the heat sink, thereby enhancing the cooling effect.

[0015] By setting baffles, the flow of lubricating oil is further restricted as it flows downward on the heat sink. The lubricating oil can flow on the baffles, making its flow direction S-shaped, thereby further increasing the contact time between the lubricating oil and the baffles and improving the cooling effect.

[0016] When the hollow baffle is used for heat dissipation, the airflow blown by the fan can enter the baffle through the first and second slots, thereby cooling the baffle and dissipating the lubricating oil on the baffle surface.

[0017] The airflow entering the baffle can be discharged through square holes one and two, thereby allowing the gas inside the baffle to flow and improving the heat dissipation capacity of the lubricating oil on the baffle surface.

[0018] By adding fins, the contact area between the heat sink and the lubricating oil is increased, thereby further improving the cooling effect of the lubricating oil. Attached Figure Description

For some known technologies, those skilled in the art can also use other alternative methods to implement the invention; moreover, the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0023] like Figures 1-4 As shown, an embodiment of this utility model provides an automated molded product loading and unloading device, including a robotic arm 1, a suction cup 2 installed at the output end of the robotic arm 1, and further including: Cooling mechanism 3 is used to cool the lubricating oil in the base of robotic arm 1. Robotic arm 1 realizes the loading and unloading of molded products, and suction cup 2 adsorbs and fixes the products. Cooling mechanism 3 cools the lubricating oil in the base of robotic arm 1 to prevent the lubricating oil temperature from being too high and the viscosity from decreasing, and to ensure that a sufficiently thick oil film is formed on the gear contact surface to maintain the lubrication effect.

[0024] like Figures 2-3 As shown, in this embodiment, the cooling mechanism 3 includes a housing 4 fixed to the side of the base of the robotic arm 1. A circulation pump 5 is fixed to the top of the housing 4, and the output end of the circulation pump 5 is connected to the top of the housing 4. The input end of the circulation pump 5 is connected to the oil outlet of the robotic arm 1 through a pipe 6. An oil delivery pump is fixed to the bottom of the housing 4, and the oil inlet of the oil delivery pump is connected to the bottom of the housing 4 through a round pipe. The oil outlet of the oil delivery pump is connected to the oil inlet of the robotic arm 1 through a pipe 7. An inverted V-shaped plate 9 is fixed to the inner wall of the housing 4. Two symmetrically arranged heat dissipation plates 10 are fixed to the inner wall of the housing 4 and below the inverted V-shaped plate 9. A sealing plate 11 is fixed to the bottom of the 10. The side of the sealing plate 11 is fixedly connected to the inner wall of the housing 4. A fan 12 is fixed at the round hole on the side of the housing 4. An air outlet 13 is opened on the side of the housing 4. The housing 4 provides a cooling space. The circulation pump 5 draws out the lubricating oil from the robotic arm 1 through the first pipe 6. The inverted V-shaped plate 9 diverts the lubricating oil to the heat sink 10. The heat sink 10 transfers the heat of the lubricating oil. The sealing plate 11 fixes the heat sink 10. The fan 12 blows out air to cool the heat sink 10. The air outlet 13 discharges the air. The oil pump sends the cooled lubricating oil back to the robotic arm 1 through the second pipe 7 to form a circulating cooling system and improve the cooling effect.

[0025] like Figure 3 As shown in this embodiment, a bracket 8 is fixed to the surface of the housing 4. The bracket 8 is fixed to the base of the robotic arm 1 by bolts. The bracket 8 fixes the housing 4 to the base of the robotic arm 1 by bolts, ensuring that the cooling mechanism 3 is installed stably and avoiding shaking during operation.

[0026] like Figure 4 As shown in this embodiment, the heat sink 10 is wavy. The wavy heat sink 10 slows down the flow rate of the lubricating oil, increases the contact time between the lubricating oil and the heat sink 10, and improves the cooling effect.

[0027] like Figure 4 As shown in this embodiment, a number of fins 15 are fixed on opposite sides of the heat sink 10. The fins 15 increase the contact area between the heat sink 10 and the lubricating oil, thereby improving the cooling effect of the lubricating oil.

[0028] like Figure 4As shown in this embodiment, several baffles 14 are fixed vertically and horizontally on opposite sides of the heat sink 10. One end of the baffle 14 is fixed to the inner wall of the housing 4, and a flow channel is formed between the other end of the baffle 14 and the inner wall of the housing 4. The flow channels at the ends of adjacent baffles 14 are staggered. The baffles 14 restrict the flow of lubricating oil, so that the lubricating oil flows in an S-shaped path, prolonging the contact time with the baffles 14 and the heat sink 10, improving the cooling effect. The staggered flow channels ensure smooth flow of lubricating oil.

[0029] like Figure 4 As shown in this embodiment, the inner wall of the baffle 14 is hollow, and a strip-shaped hole 1 is opened at the end of the baffle 14. A strip-shaped hole 2 is opened on the surface of the heat sink 10. The strip-shaped hole 1 and the strip-shaped hole 2 are connected. The hollow baffle 14, together with the strip-shaped hole 1 and the strip-shaped hole 2, allows the airflow blown out by the fan 12 to enter the interior of the baffle 14, cool the baffle 14, and then cool the lubricating oil on its surface, thereby improving the heat dissipation effect.

[0030] like Figure 4 As shown in this embodiment, a square hole 1 is provided at the end of the baffle 14, and a square hole 2 is provided on the surface of the housing 4. The square hole 1 and the square hole 2 are connected, so that the airflow inside the baffle 14 can be discharged, forming an airflow circulation, improving the heat dissipation capacity of the baffle 14, and further improving the cooling effect of the lubricating oil.

[0031] Working principle: When the circulation pump 5 is started, the lubricating oil in the base of the robotic arm 1 is drawn out through the pipe 6, and the lubricating oil is discharged from the top of the housing 4. After the lubricating oil comes into contact with the inverted V-shaped plate 9, it splits to both sides and flows onto the wavy surface of the heat sink 10. The fins 15 on the opposite side of the heat sink 10 increase the contact area between the lubricating oil and the heat sink 10. When the lubricating oil flows downward along the heat sink 10, the baffle 14 restricts its flow, causing the lubricating oil to flow in an S-shaped path and prolonging the contact time. When the fan 12 starts, the airflow blown out cools the heat sink 10 and the baffle 14, thereby cooling the lubricating oil. At the same time, the airflow enters the hollow baffle 14 through the first strip hole at the end of the baffle 14 and the second strip hole on the surface of the heat sink 10. After cooling the baffle 14, the airflow is discharged through the first square hole at the end of the baffle 14 and the second square hole on the surface of the housing 4. Finally, the airflow is discharged from the air outlet 13 on the side of the housing 4. After cooling, the lubricating oil flows to the bottom of the housing 4. The oil pump is started and the lubricating oil is transported back to the base of the robotic arm 1 through the second pipe 7, forming a circulating cooling system.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
