Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, and more specifically to an automatic flipping device. Background Technology

[0002] In industries such as electronics manufacturing, automotive assembly, and food packaging, it is often necessary to perform operations on both sides of a product (such as welding, inspection, and printing). In traditional processes, the flipping operation is mostly done manually, which presents the following problems:

[0003] Inefficient: Manual flipping is slow and difficult to match the pace of automated production lines;

[0004] High cost: Specialized operators are required, increasing labor costs;

[0005] Safety hazards: Manual operation may cause the product to fall or cause personal injury;

[0006] Poor consistency: It is difficult to guarantee the accuracy of the flipping angle and position, which affects product quality.

[0007] While existing automated flipping equipment can partially solve the above problems, it still has the following shortcomings:

[0008] Complex structure and high maintenance costs;

[0009] It has poor adaptability and is difficult to adapt to products of different sizes or weights;

[0010] It relies on high-precision sensors or servo systems, resulting in higher costs.

[0011] Therefore, there is an urgent need for an automatic flipping device that is simple in structure, highly versatile, and cost-controllable. Utility Model Content

[0020] In some embodiments, the control unit controls the negative pressure of the suction cup by adjusting the air pressure of the solenoid valve.

[0021] In some embodiments, the operating speed of the conveyor line is adjustable to achieve uniform speed transmission.

[0022] In some embodiments, the rotational action of the rotary cylinder includes:

[0023] Rotate 180 degrees clockwise to flip the product;

[0024] Rotate in the opposite direction to reset to the initial position.

[0026] In some embodiments, the relative position between the fixing plate and the conveyor line is adjustable to accommodate products of different sizes.

[0027] The advantages of this utility model compared with the prior art are:

[0028] Highly efficient automation: single flip cycle ≤ 3 seconds, significantly improving production efficiency;

[0040] The following will combine Figures 1-2 This application provides a detailed description of an automatic flipping device according to its embodiments. It is worth noting that the following embodiments are merely illustrative of this application and do not constitute a limitation thereof.

[0041] Example 1:

[0042] See Figures 1-2 As shown, an automatic flipping device includes:

[0043] Conveyor line 4 is used to transport product 1;

[0044] Fixed plate 2 is disposed on one side of the conveyor line;

[0045] Suction cup 5 is mounted on the fixing plate and is used to adsorb the product; for thin and light products (such as PCB boards), 8 suction cups are arranged in a rectangular pattern.

[0046] Rotary cylinder 3, connected to the fixed plate, is used to drive the fixed plate and the adsorbed product to rotate 180 degrees.

[0047] The control unit, including a PLC and solenoid valves, is configured to control the adsorption and release of the suction cup, and the rotation direction of the rotary cylinder. Specifically:

[0048] Conveyor line 4: Utilizes a belt conveyor mechanism driven by a variable frequency motor, with an adjustable speed range of 0.1-1.0 m / s;

[0049] Fixed plate 2: Connected to the side of conveyor line 4 via slide rail, with a lateral adjustment range of ±50mm;

[0050] Suction cup 5: Uses a silicone vacuum suction cup with a negative pressure setting of -50kPa to -80kPa;

[0051] Rotary cylinder 3: MSQ series 180° double-acting cylinder, with a rotational torque ≥10N·m;

[0052] Control unit: PLC (Mitsubishi FX series) and solenoid valve assembly (SMC VQZ series), which receives photoelectric sensor signals through I / O modules.

[0053] To put it more precisely:

[0054] Conveyor line 4: Employs a belt conveyor mechanism for the continuous transport of product 1 to be processed. The operating speed of conveyor line 4 can be adjusted via a frequency converter to achieve uniform or variable speed transport.

[0055] Fixed plate 2: Made of aluminum alloy, it is fixed on one side of the conveyor line 4. Its position can be adjusted laterally by the slide rail mechanism to accommodate products 1 of different sizes.

[0056] Suction cup 5: Multiple vacuum suction cups are evenly distributed on the fixed plate 2 and connected to the vacuum generator via air pipes for adsorbing product 1. The adsorption force of the suction cup 5 is regulated by a solenoid valve to ensure stable gripping.

[0057] Rotary cylinder 3: A 180° double-acting rotary cylinder is selected and connected to the fixed plate 2 via a flange. The air inlet of the rotary cylinder 3 is connected to a solenoid valve, and its forward and reverse rotation is controlled by a PLC.

[0058] Control unit: includes a PLC (Programmable Logic Controller) and a solenoid valve assembly. The PLC receives sensor signals (such as product arrival signals) and controls the opening and closing of the solenoid valves to synchronize the suction / release of the suction cup 5 with the movement of the rotary cylinder 3.

[0059] The specific operating steps of the device are as follows:

[0060] Step S1: Initialization Preparation

[0061] Introduce compressed air and check the air circuit for leaks;

[0062] The negative pressure of suction cup 5 is set to -60kPa via PLC (which can be adjusted according to the weight of the product);

[0063] Start conveyor line 4 and adjust the frequency converter to make conveyor line 4 run at a constant speed of 0.5m / s.

[0064] Step S2: Product Positioning and Adsorption

[0065] The robotic arm picks up product 1 from the upstream station and precisely places it on the suction cup 5 of the fixed plate 2;

[0066] After the PLC detects the product arrival signal, it triggers the solenoid valve, and the suction cup 5 immediately picks up product 1.

[0067] Step S3: Product flipping

[0068] The PLC controls the rotary cylinder 3 to rotate 180° in the forward direction, which drives the fixed plate 2 and the adsorbed product 1 to flip synchronously.

[0069] After the flipping is completed, the PLC sends a signal to release the vacuum of the suction cup 5, and product 1 falls back to the conveyor line 4 and continues to be conveyed to the next station.

[0070] Step S4: Reset and Loop

[0071] Rotary cylinder 3 rotates 180° in the opposite direction to return to its initial position;

[0072] Suction cup 5 re-enters the adsorption state, waiting for the next product 1 to enter.

[0073] This invention can be widely applied in production lines of industries such as electronics, automobiles, and food, and is especially suitable for scenarios requiring double-sided processing (such as PCB board welding and double-sided label printing), and has significant industrialization value.

[0074] Tests have shown that production lines using this device achieve a 40% increase in efficiency, a 60% reduction in labor costs, and a failure rate of ≤0.5 times / thousand hours, demonstrating significant value for industrialization and promotion.

[0075] The above description is only a preferred embodiment of the present utility model and is used to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
