Description

Technical Field

[0001] This utility model specifically relates to a robotic arm picking device for a blister packaging machine. Background Technology

[0002] Currently, different packaging methods are required for different toys in the toy production and packaging process. The simplest and most direct method is to use a set of packaging film, while for toys that emphasize display, paper and plastic are used for vacuum forming, which not only displays the toy but also provides effective packaging and protection.

[0003] Traditional vacuum forming machines often rely on manual operation or simple mechanical devices for loading and unloading workpieces after thermoforming. This leads to problems such as low efficiency, poor product consistency, and easy damage to workpieces. In addition, traditional vacuum forming machines have pauses between processes such as forming, cooling, unloading, and conveying, requiring manual intervention or equipment waiting, which limits the efficiency of the entire line. Moreover, manual unloading also poses safety issues, as improper operation by workers can easily result in burns. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a robotic arm picking device for blister packaging machines.

[0005] The technical solution adopted by this utility model to solve its technical problem is: A robotic arm for a thermoforming machine includes a machine tool, a pneumatic thermopressing mechanism mounted above the machine tool, a rotary disk located below the pneumatic thermopressing mechanism and supported by a rotary motor, a workpiece placement mold fixedly mounted on the rotary disk, a robotic arm mounted above the machine tool capable of lateral telescopic movement, and a conveyor belt located on the side of the machine tool to cooperate with the robotic arm for delivery. The robotic arm includes a steel pipe with one end bolted to the machine tool, a telescopic cylinder fixedly mounted above the steel pipe via a mounting base, an L-shaped bracket welded to the side of the steel pipe with a through hole at the upper end, a guide post passing through the through hole at the upper end of the L-shaped bracket, a robotic arm fixedly mounted on the side with the output end of the telescopic cylinder and the guide post, a frame fixedly mounted with the output end of the robotic arm, a copper tube movably mounted below the frame with nuts screwed onto both ends for limiting, a soft rubber nozzle mounted at the lower end of the copper tube, and a first pressure-relieving spring fitted on the copper tube. The copper tube is connected to an air tank with a solenoid valve via a flexible hose.

[0006] Preferably, a positioning block is fixedly installed on the output end of the picking cylinder by screws.

[0007] Preferably, the frame includes an upper horizontal block, vertically downward connecting columns located at both ends of the upper horizontal block, and a lower horizontal block fixed to the connecting columns and parallel to the upper horizontal block.

[0008] Preferably, the pneumatic hot pressing mechanism includes a pressing cylinder, a pressing plate fixedly installed to the output end of the pressing cylinder, a pressing stud passing through the edge of the pressing plate, a second pressure relief spring fitted on the pressing stud, a movable pressure plate fixedly installed to the pressing stud, and a hot pressing plate laid on the lower surface of the movable pressure plate.

[0009] Preferably, the rotary disk includes a rotary disk body supported by a rotary motor, a rubber pad laid on the upper surface of the rotary disk body, and a terminal block fixedly installed in the center of the rotary disk body and connected to the workpiece placement mold base by a wire.

[0010] Preferably, the workpiece placement mold base includes a mold base body, a workpiece receiving cavity opened inside the mold base body, an insert groove opened above the mold base body and located at the edge of the workpiece receiving cavity, an electric heating frame tightly fitted with the insert groove, and workpiece limiting studs distributed at the edge of the insert groove and screwed into the mold base body.

[0011] The beneficial effects of this utility model are as follows: 1. Through the coordinated work of the rotary table and the picking robot, the continuous automation of the hot pressing and workpiece picking process is realized. After the workpiece is hot pressed at one station, the rotary table can rotate it to the picking station, and the robot will pick it up and place it on the conveyor belt at the same time, forming an uninterrupted production cycle, which greatly reduces manual intervention and waiting time between processes. 2. The picking robot uses guide columns to ensure the straightness of vertical movement, and the first pressure relief spring provides cushioning for the suction cup assembly composed of copper tube and soft rubber nozzle. This design makes the nozzle flexible when contacting the workpiece, which can effectively prevent indentation or scratches on the surface of the finished workpiece. It is especially suitable for fragile blister products. The telescopic cylinder provides precise lateral movement, ensuring the accuracy of picking and placing positions. Attached Figure Description

Detailed Implementation

[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0014] Example like Figure 1-4 As shown, a robotic arm picking device for a vacuum forming machine includes a machine tool 1, a pneumatic hot pressing mechanism 2 mounted above the machine tool 1, a rotary disk 3 located below the pneumatic hot pressing mechanism 2 and supported by a rotary motor, a workpiece placement mold base 4 fixedly mounted on the rotary disk 3, a picking robotic arm 5 mounted above the machine tool 1 and capable of lateral telescopic movement, and a conveyor belt 6 located on the side of the machine tool 1 and used in conjunction with the picking robotic arm 5 to deliver goods.

[0015] The pneumatic hot pressing mechanism 2 includes a pressing cylinder 21, a pressing plate 22 fixedly installed with the output end of the pressing cylinder 21, a pressing stud 23 passing through the edge of the pressing plate 22, a second pressure relief spring 24 fitted on the pressing stud 23, a movable pressure plate 25 fixedly installed with the pressing stud 23, and a hot pressing plate 26 laid on the lower surface of the movable pressure plate 25.

[0016] It should be further explained that the movable pressure plate 25 is connected to the lower pressure plate 22 through the lower pressure stud 23 and the second pressure relief spring 24. This design allows the hot pressure plate 26 to compress the second pressure relief spring 24 first when it contacts the workpiece and the workpiece placement mold 4. The pressure increases gradually, which plays an effective role in buffering and equalizing pressure, protecting the workpiece placement mold 4 and the workpiece, and improving the pressing quality.

[0017] The rotating disk 3 includes a rotating disk body 31 supported by a rotating motor, a rubber pad 32 laid on the upper surface of the rotating disk body 31, and a terminal block 33 fixedly installed in the center of the rotating disk body 31 and connected to the workpiece placement mold base 4 by a wire.

[0018] It should be further explained that when the workpiece placement mold 4 is installed on the rotary table 3, while the workpiece placement mold at one station is undergoing hot pressing, the workpiece already formed at the workpiece placement mold at another station can be simultaneously picked up by the picking robot 5. This separation and parallel operation of the "hot pressing" and "picking" stations realizes the continuity of production, eliminates the waiting time between processes, greatly improves production efficiency, and also reduces the safety problems of manual picking, avoiding burn accidents that are easy to occur due to workers' non-standard operation.

[0019] The workpiece placement mold base 4 includes a mold base body 41, a workpiece receiving cavity 42 opened inside the mold base body 41, an insert groove 43 opened above the mold base body 41 and located at the edge of the workpiece receiving cavity 42, an electric heating frame 44 tightly fitted and mounted with the insert groove 43, and workpiece limiting studs 45 distributed at the edge of the insert groove 43 and screwed into the mold base body 41.

[0020] It should be further explained that the mold base body 41 is designed with a standard workpiece receiving cavity 42 and an insert groove 43, which can quickly clamp the electric heating frame 44. The workpiece limiting stud 45 can prevent the workpiece from shifting, which helps to enhance the reliability of the workpiece hot pressing composite.

[0021] The picking robot 5 includes a steel pipe 51 fixed to the machine tool 1 at one end by bolts, a telescopic cylinder 52 fixedly mounted on the steel pipe 51 by a mounting base, an L-shaped bracket 53 welded to the side of the steel pipe 51 with a through hole at the upper end, a guide post 54 passing through the through hole at the upper end of the L-shaped bracket 53, a picking cylinder 55 fixedly mounted on the side with the output end of the telescopic cylinder 52 and the guide post 54, a frame 56 fixedly mounted with the output end of the picking cylinder 55, a copper pipe 57 movably mounted below the frame 56 with nuts screwed on both ends for limiting, a soft rubber suction nozzle 58 mounted on the lower end of the copper pipe 57, and a first pressure relief spring 59 fitted on the copper pipe 57. The copper pipe 57 is connected to an air tank with a solenoid valve through a hose.

[0022] It should be further explained that the use of a soft rubber suction nozzle 58 for suction avoids damage to the workpiece surface caused by mechanical clamping. The first pressure relief spring 59 is a spring component mounted on the copper tube 57, which enables the soft rubber suction nozzle 58 to further buffer when contacting the workpiece surface, adapting to different working plane heights, providing a gentle contact force, and preventing hard impacts from crushing the workpiece. The picking cylinder 55 is guided by the guide column 54 to ensure that its up and down movement is smooth and vertical, and will not scratch the workpiece due to shaking or tilting.

[0023] A positioning block 551 is fixedly installed on the output end of the picking cylinder 55 by screws. Specifically, it is used to position the mounting frame 56.

[0024] The frame 56 includes an upper horizontal block 561, vertically downward connecting posts 562 located at both ends of the upper horizontal block 561, and a lower horizontal block 563 fixed to the connecting posts 562 and parallel to the upper horizontal block 561. Specifically, the upper horizontal block 561 is positioned by a positioning block 551, which allows for more stable fixing to the output end of the picking cylinder 55. In addition, a copper tube 57 vertically passes through the lower horizontal block 563, and is limited at both ends by nuts screwed on.

[0025] like Figure 5As shown, the workpiece is manually placed on the workpiece placement mold 4. With the clockwise rotation of the rotating disc 31, it moves to below the pneumatic hot pressing mechanism 2, where it is pressed and heat-sealed. Then, the rotating disc 31 continues to rotate, moving the workpiece placement mold 4 with the workpiece underneath to below the picking robot 5. Simultaneously, the picking cylinder 55 extends, contacting and picking up the workpiece through the soft rubber suction nozzle 58. Then, the telescopic cylinder 52 is activated, extending in the direction of arrow a to transfer the workpiece onto the conveyor belt 6 and lower it. At this point, one end of the workpiece is on the conveyor belt 6, and the other end is on the rubber pad 32 of the rotating disc 31. However, due to the forward movement of the conveyor belt 6 and the continuous rotation of the rotating disc 31 adjusting the position of the workpiece placement mold 4, the end of the workpiece on the conveyor belt 6 moves in the direction of arrow b, while the end of the workpiece on the rotating disc 31 rotates in the direction of arrow C under the friction of the rubber pad 32, until it completely falls onto the conveyor belt 6 and is then conveyed out by the conveyor belt 6.

[0026] In summary, this device improves efficiency by enabling parallel processing through a rotary table, protects workpieces and increases yield through a buffered flexible robotic arm and a hot pressing mechanism, and enhances equipment versatility through a modular mold base design.

All other modifications, substitutions or alterations made to the above structure of this utility model based on the above content of this utility model and in accordance with the common technical knowledge and conventional means in the field, without departing from the basic technical idea of ​​this utility model, shall fall within the scope of protection of this utility model.
