Description

Technical Field

[0001] This utility model relates to the field of blister tray forming, unloading and conveying technology, specifically an automatic unloading and conveying device for blister trays after forming. Background Technology

[0002] An automatic unloading and conveying device for blister trays after forming is a specialized piece of equipment on blister production lines used to automatically remove the blister trays from the mold and transport them to the next process after forming. It primarily addresses the problems of low efficiency and easy scratching of blister trays during manual unloading. It typically consists of a demolding mechanism, a conveyor belt, positioning and guiding components, and a sensing and control module. Some models feature anti-scratch pads. During operation, the sensing module detects the blister tray after forming, and the demolding mechanism ejects or absorbs it from the mold. Subsequently, the conveyor belt starts, and with the assistance of the guiding components, smoothly transports the blister tray to the designated position. This device is suitable for mass production of blister trays, automating unloading and conveying, avoiding damage caused by manual contact, and improving production efficiency and product qualification rate. In existing technical solutions, manual unloading of blister trays after molding is often the primary method. This is not only inefficient and difficult to meet the needs of mass production, but also prone to scratching the surface of the blister tray due to improper force control during manual operation, affecting the product qualification rate. Although some automated unloading devices can achieve demolding, they lack a continuous conveying mechanism after unloading, requiring the blister tray to be transferred to the next process, which increases the complexity of the production process. Some devices have insufficient positioning accuracy of the demolding mechanism, which is prone to deviation when adsorbing or ejecting the blister tray, causing the blister tray to fall off or get stuck with the mold, further reducing the stability and reliability of unloading. In order to solve this technical problem, this utility model proposes an automatic unloading and conveying device for blister trays after molding. Utility Model Content

Although some automated unloading devices can achieve demolding, they lack a continuous conveying mechanism after unloading, requiring the blister tray to be transferred to the next process, which increases the complexity of the production process. Some devices have insufficient positioning accuracy of the demolding mechanism, which is prone to deviation when adsorbing or ejecting the blister tray, causing the blister tray to fall off or get stuck with the mold, further reducing the stability and reliability of unloading. In order to solve this technical problem, this utility model proposes an automatic unloading and conveying device for blister trays after molding.

[0013] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0014] Please see Figure 1-4 This utility model provides a technical solution: Example 1: An automatic unloading and conveying device for blister trays after molding, comprising a workbench 1, a support frame 2 fixedly connected to the top of the workbench 1, slide rods 3 fixedly connected to both sides of the top of the support frame 2, electric push rods 4 fixedly connected to both sides of the top of the support frame 2, a connecting plate 6 fixedly connected to the output end of the electric push rods 4, an electric push rod 7 fixedly connected to the bottom of the connecting plate 6, a U-shaped frame 8 fixedly connected to the output end of the electric push rod 7, an electric push rod 9 fixedly connected inside the U-shaped frame 8, a top plate 11 fixedly connected to the output end of the electric push rod 9, a pair of suction cups 14 fixedly connected to the bottom of the top plate 11, a vacuum pump 12 fixedly connected to the top of the top plate 11, and an exhaust pipe 13 fixedly connected to the output end of the vacuum pump 12. Limiting grooves 10 are provided on both sides of the connecting plate 6. The U-shaped frame 8 is slidably connected in the limiting grooves 10. A pair of positioning rods 18 are fixedly connected to the top of the top plate 11. The positioning rods 18 are slidably connected to the two side walls of the U-shaped frame 8. A conveyor belt 19 is fixedly installed on one side of the top of the workbench 1. A conveyor belt 20 is fixedly connected to the top of the other side of the top of the workbench 1. A motor 21 is provided outside the conveyor belt 19 and the conveyor belt 20. A mold 22 is provided on the conveyor belt 20. A blister tray body 23 is provided inside the mold 22. A pair of telescopic rods 15 are fixedly connected to the bottom of the top plate 11. A pressure block 17 is fixedly connected to the other end of the telescopic rod 15. A spring 16 is fixedly connected between the pressure block 17 and the bottom end of the telescopic rod 15.

[0015] When using the automatic unloading and conveying device after the blister tray is formed, the blister tray body 23 is formed in the mold 22 and then conveyed to the designated unloading position by the conveyor belt 20. The electric push rod 4 is activated, and its output end pushes the connecting plate 6 to slide along the slide rod 3, moving the lower U-shaped frame 8, the top plate 11, and the suction cup 14 above the blister tray body. Then, the electric push rod 7 is activated, pushing the U-shaped frame down along the limiting groove 10 of the connecting plate, bringing the suction cup close to the blister tray body. The vacuum pump 12 creates a negative pressure inside the suction cup through the exhaust pipe 13, adsorbing the blister tray body. Subsequently... Electric push rod 2 moves upward, causing the blister tray body to detach from the mold. Electric push rod 1 then moves it above conveyor belt 19. At this time, electric push rod 3 9 is activated to push the top plate downward. The telescopic rod 15 and pressure block 17 at the bottom of the top plate first contact the surface of conveyor belt 1 and compress the spring 16. After the suction cup releases the negative pressure, the blister tray body falls onto conveyor belt 1 and is transported to the next process by conveyor belt 1. Positioning rod 18 ensures the stability of the top plate movement. The actions of each electric push rod and the conveyor belt are controlled in coordination by motor 21 to realize automatic unloading and conveying of the blister tray after it is formed, thereby improving production efficiency.

[0016] Working principle: When using the automatic unloading and conveying device after the blister tray is formed, the blister tray body 23 is first formed in the mold 22. The mold is then conveyed to the designated unloading position by the conveyor belt 20. The electric push rod 4 is activated, and its output end pushes the connecting plate 6 to slide along the slide rod 3, which moves the U-shaped frame 8, the top plate 11, and the suction cup 14 above the blister tray body. Then, the electric push rod 7 is activated, pushing the U-shaped frame down along the limiting groove 10 of the connecting plate, so that the suction cup approaches the blister tray body. The vacuum pump 12 is activated, and a negative pressure is formed inside the suction cup through the exhaust pipe 13, thereby adsorbing the blister tray body. Then, electric push rod 2 moves upward, causing the blister tray body to detach from the mold. Then, electric push rod 1 is activated to move the blister tray body above conveyor belt 19. At this time, electric push rod 3 is activated to push the top plate downward. The telescopic rod 15 and pressure block 17 at the bottom of the top plate first contact the surface of conveyor belt 1, compressing the spring 16. Then, the suction cup releases the negative pressure, and the blister tray body falls onto conveyor belt 1 and is transported to the next process by conveyor belt 1. Positioning rod 18 ensures that the top plate moves stably. The actions of each electric push rod and the conveyor belt are controlled in coordination by motor 21 to realize automatic unloading and transportation of the blister tray after it is formed, thereby improving production efficiency.
