Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and in particular to an intelligent metering and material-taking device based on PLC control. Background Art

[0002] Our team discovered that manufacturers of switch panels, switch boxes, socket panels, and socket boxes, which are used in everyday life, still rely heavily on manual labor for the metering, transportation, and production of raw materials (amino molding compound powder), often in harsh production environments. This not only poses safety risks and pollutes the environment, but also results in significant raw material losses, low returns, and inconsistent product quality.

[0003] Since the raw materials are in powder form, workers have to make large movements when measuring. In addition, the process involves heat treatment, which results in high ambient temperatures. Many workers use electric fans to cool themselves down, which causes dust to be raised during the measuring process, thus creating a harsh environment.

[0004] Manual operation requires measuring the raw materials, placing them into the mold and pressing them, and then taking them out after pressing is completed. This is labor-intensive, and the equipment operated by the workers is hydraulic machinery. The pressure of the press is generally as high as 100-160 / ton. Due to product process problems, heating is required, and the temperature of the mold heating is generally as high as 120-170 / degrees, which is quite dangerous for the operators.

[0005] In addition, the raw materials are manually weighed using a balance scale. Due to the fast processing speed and many manual operation processes, the manual measurement is basically carried out at a very fast speed. As a result, the measurement of the raw materials is determined when the balance scale fails to balance, and the raw materials are basically weighed more heavily, resulting in waste of raw materials.

[0030] In this embodiment, the feeding assembly includes a feeding pipe 4, a feeding screw 5 and a stepper motor 26. The feeding pipe 4 is horizontally installed on the discharge port of the hopper 3, the feeding screw 5 is arranged inside the feeding pipe, and the stepper motor 26 is installed at one end of the feeding pipe 4.

[0031] In this embodiment, the metering assembly includes a metering hopper 6, a flip motor 34, a flip cover 27, a pressure sensor 28, a panel 31, a shaft 33 and a plurality of bearings 32. The upper end of the metering hopper 6 is expanded outward to form a feeding end of a trumpet-shaped structure. The lower end of the metering hopper 6 is opened.

A plurality of connecting rods 35 are installed between the flip cover 27 and the shaft 33.

[0032] In this embodiment, the adsorption assembly includes a telescopic cylinder 17, a fixed plate 18 and a plurality of material picking suction cups 19. The telescopic cylinder 17 is installed on the bottom surface of the horizontal plate, and the fixed plate 18 is arranged below the horizontal plate 13. The piston rod of the telescopic cylinder 17 passes through the horizontal plate 13 and is installed on the top surface of the fixed plate 18. An air cavity 37 is formed inside the fixed plate 18. A plurality of connecting pipes 41 are installed on the bottom surface of the fixed plate 18. The material picking suction cups 19 are all threadedly connected to the bottom of the connecting pipe 41. An air suction pipe 38 connected to the air cavity is installed at one end of the fixed plate 18, and a hose 39 is installed at one end of the suction pipe 38. A vacuum pump is installed at the other end of the hose 39. The suction force generated by the vacuum pump acts on the air cavity through the hose and the connecting pipe, so that suction is generated on the material picking suction cup connected to the air cavity.

[0033] In this embodiment, a fixing frame 23 is installed between the feeding assembly, the metering assembly and the positioning hopper 8; a rack 24 is installed on one side of the electrical cabinet 9, and the other end of the rack 24 is installed on a side surface of the hopper 3. The hopper, the feeding assembly, the metering assembly and the positioning hopper can be fixed to the electrical cabinet through the rack and the fixing frame.

[0034] In this embodiment, a stirring motor 1 is installed at the center of the top surface of the hopper 3. The rotating shaft of the stirring motor 1 passes through the top surface of the hopper and extends to the inside, and a stirring rod 2 is installed through a coupling. A feeding pipe 25 is installed on the top surface of the hopper 3 on one side of the stirring motor, and the material can be poured into the hopper along the feeding pipe.

[0035] In this embodiment, universal wheels 22 with brakes are installed on the four corners of the bottom surface of the electrical cabinet 9. The universal wheels facilitate the movement of the device and can be locked after movement.

[0036] Among them, the conveying component and the metering component are both controlled by a PLC controller with a touch screen. The metering parameters are set on the touch screen through a combination of weighing and volumetric methods.

[0037] After the material is poured into the hopper, the stirring motor is started first. The start of the stirring motor drives the stirring rod. The rotating stirring rod can mix the internal materials evenly. After the material enters the conveying pipe, the stepper motor is started to drive the conveying screw to rotate, and accurate metering is achieved through 3 decelerations. For example: when I need 100g of material, the conveying screw will first start the initial speed, and then execute the medium speed when the metering reaches 90g, and execute the low speed when the metering reaches 97g, until it stops conveying when it reaches 100g. The discharged material can fall into the metering hopper and exert its weight on the panel and pressure sensor. The pressure sensor can accurately know whether the material meets the standard. After meeting the standard, the flip motor is started. The start of the flip motor drives the shaft, connecting rod and flip cover, so that the flip cover is opened from the bottom of the metering hopper. At this time, the internal material can fall into the mold material box along the positioning hopper;

[0038] After the above is completed, the X-axis electric slide is started to move the mobile platform on the X-axis electric slide to the right. The movement of the mobile platform drives the cross plate and the adsorption assembly until the adsorption assembly is moved between the opened molds. At this time, the telescopic cylinder and the vacuum pump are started. The activation of the telescopic cylinder can make the piston rod extend downward and drive the fixed plate and the material removal suction cup until the material removal suction cup is adsorbed on the sheet metal of the mold. After adsorption and fixation, the piston rod of the telescopic cylinder is retracted to lift the sheet metal from the lower mold. After completion, continue to move the cross plate to the right until the mold material box is relative to the lower mold up and down. After starting the extraction cylinder, the cover plate will be removed from the bottom of the mold material box, so that the lower end of the mold material box is opened, and the material inside can fall directly into the lower mold. After the cross plate retreats, the vacuum pump can be turned off. After the material removal suction cup loses suction, the adsorbed sheet metal can fall, which is convenient for taking the material.

[0039] Among them, the process of taking the product is through the material taking suction cup. Since the surface of the product is smooth, the material taking suction cup can be used to take the product, and the damage to the product surface is reduced. The suction cup is made of silicone and can withstand high temperatures of about 220 degrees. This process perfectly solves the problems of inaccurate and uneven manual measurement, spillage of raw material dust and all kinds of harm to people. It not only effectively controls risks, improves product quality, but also enhances corporate benefits.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection defined in the claims.
