Description

Technical Field

[0001] The present invention belongs to the field of mechanical automation, and particularly relates to a fully automatic and efficient red envelope wrapping robot. Background Art

[0002] Red envelopes are also called lucky money. During the Spring Festival, elders usually give red envelopes to children, meaning peace and smoothness. Due to their auspicious meaning, sometimes shopping malls, communities, large companies will distribute red envelopes in batches when starting work during the Spring Festival, or schools will do so when starting school at the beginning of the Spring Festival.

[0003] Traditionally, the steps for people to wrap red envelopes are as follows: First, take out a red envelope, then open the red envelope, count a certain number of coins, put the coins into the red envelope by hand, then lift the ear of the red envelope, and then fold the cover of the red envelope and insert it into the ear to complete the whole process of wrapping the red envelope.

[0004] Since coins circulate widely in the market and are touched by many people, they often carry a lot of bacteria. If you directly touch the coins with your hands to wrap red envelopes, the hygiene situation is difficult to guarantee; in addition, because some newly issued coins are strongly adhered to each other, and people's fingers are relatively thick, it is sometimes difficult to count them, and there may be errors in the number of coins when wrapping red envelopes; multiple red envelope wrapping processes cannot be carried out simultaneously, and the speed of wrapping red envelopes is slow and the efficiency is not high.

[0005] Therefore, people are eager to develop a fully automatic and efficient red envelope wrapping robot. Summary of the Invention

[0047] The present invention will be further described in detail below.

[0048] As Figure 1 shown, a fully automatic and efficient red - envelope wrapping robot includes a frame 1, and a red - envelope taking device, a money - loading device, a sealing device, a transfer device and a control device are arranged on the frame 1;

[0049] The red - envelope taking device is used to take out red envelopes and convey them to the transfer device;

[0050] The transfer device is used to sequentially transfer the red envelopes taken out by the red - envelope taking device to the money - loading device and the sealing device;

[0051] The money - loading device is used to load coins into the red envelopes transferred by the transfer device;

[0052] The sealing device is used to seal the red envelopes loaded with coins transferred by the transfer device;

[0053] The control device is used to control the actions of the transfer device, the red - envelope taking device, the money - loading device and the sealing device.

[0054] As Figure 4 shown, specifically, the transfer device includes a stepper motor 21 and a turntable 3. The stepper motor 21 is fixedly arranged on the frame 1, a large disc gear 31 is arranged at the center of the turntable 3, and the stepper motor gear 22 meshes with the large disc gear 31 for driving transmission to drive the turntable 3 to rotate on the frame 1.

[0055] As Figure 1 - Figure 2As shown in the figure, the turntable 3 is provided with 4 clamping parts 32 respectively located around the turntable 3, and the distance between each clamping part 32 and the center of the turntable 3 is equal. The clamping part 32 is matched with the shape of the red envelope, and the width of the clamping part 32 is equal to or slightly larger than the width of the red envelope for loading the red envelope. The clamping part 32 is provided with 3 side walls and has an opening facing the outside of the turntable 3.

[0056] The red envelope taking device and the sealing device are symmetrically arranged on the left and right sides of the turntable 3, the money loading device is arranged above the turntable 3, and a finished product collecting box 8 is arranged below the turntable 3.

[0057] The stepping motor 21 precisely controls the rotation angle of the turntable 3. When any one of the clamping parts 32 corresponds to the red envelope taking device, the remaining 3 clamping parts 32 respectively correspond to the money loading device, the sealing device and the finished product collecting box 8 one by one.

[0058] On both sides of each clamping part 32, there are respectively arranged opening servo motors 33, and the opening servo motors 33 are connected with opening lever rods 34. When the red envelope is loaded into the clamping part 32, the opening servo motors 33 on both sides of the clamping part 32 drive the opening lever rods 34 to rotate inwards simultaneously, clamping both sides of the red envelope to ensure that the red envelope will not fall off from the clamping part 32 during the rotation of the turntable 3. At the same time, after both sides of the red envelope are clamped, the red envelope is deformed and the red envelope opening is opened, facilitating the loading of coins into the red envelope.

[0059] The red envelope taking device includes a pushing servo motor 41, a pushing gear 42, a pushing rack 43 and an inclined push plate 44 which are in meshing transmission. The pushing servo motor 41 is fixedly connected to the frame 1 and connected to the pushing gear 42 for driving the pushing gear 42 to rotate and driving the pushing rack 43 to move linearly.

[0060] An empty red envelope to be filled with money is placed on one side of the inclined push plate 44. The inclination angle of the inclined push plate 44 is 80°. When the red envelope is placed horizontally and leans against the inclined push plate 44, it can stand upright without slipping. The inclined push plate 44 is arranged on one side of the turntable 3 and fixedly connected to one end of the pushing rack 43.

[0061] A detection device, preferably an infrared pair of light switches 45, is arranged between the inclined push plate 44 and the turntable 3.

[0062] When the pushing rack 43 drives the inclined push plate 44 to push out the first red envelope, the infrared pair of light switches 45 is blocked and sends a signal to the control device. After receiving the signal, the control device stops the action of the pushing servo motor 41 and the inclined push plate 44 stops moving forward.

[0063] As Figure 3 、 Figure 4 As shown in the figure, the negative pressure suction device includes an air pump and a suction cup 51. The air pump is connected to the suction cup 51 for providing negative pressure attraction for the suction cup 51.

[0064] On the frame 1, there is a negative pressure servo 52, a negatively pressured gear 53 and a negatively pressured rack 54 that are meshed and driven. The negative pressure servo 52 is fixedly connected to the frame 1 and connected to the negative pressure gear 53, and is used to drive the negative pressure gear 53 to rotate and drive the negative pressure rack 54 to move linearly.

[0065] The suction cup 51 is fixedly connected to the negative pressure rack 54 and is driven by the negative pressure rack 54 to move in the direction of the inclined push plate 44.

[0066] The turntable 3 has a through hole in the clamping portion 32. The suction cup 51 passes through the through hole of the clamping portion 32 to attract the red envelopes pushed out by the inclined push plate 44, and then retracts backward through the through hole of the clamping portion 32 to load the red envelopes into the clamping portion 32. After the opening servo 33 on both sides of the clamping portion 32 clamps the red envelopes, the suction cup 51 stops attracting the red envelopes. At this time, the turntable 3 can rotate to transfer the red envelopes to the money-loading device at the next station for the money-loading operation. At the same time, after the first red envelope is sucked away, the infrared pair-switch 45 is no longer blocked and sends a signal to the control device. After receiving the signal, the control device starts the pushing servo 41, and the inclined push plate 44 continues to move forward to push out the second red envelope, and so on, forming a continuous red envelope wrapping action.

[0067] As Figure 5 shown, the money-loading device includes a money-sorting device. The money-sorting device includes a money-sorting ramp 61, a money-sorting motor 62, and a first friction wheel 63 and a second friction wheel 64 that are driven to rotate by the money-sorting motor 62. The money-sorting ramp 61 is used to place multiple coins to be distributed and make the coins slide downward.

[0068] The first friction wheel 63 and the second friction wheel 64 are arranged oppositely and rotate in the same direction.

[0069] Specifically, both the first friction wheel 63 and the second friction wheel 64 are arranged at the end of the money-sorting ramp 61. The first friction wheel 63 is arranged below the money-sorting ramp 61, and the second friction wheel 64 is arranged above the money-sorting ramp 61. There is a first gap for the coins to pass between the first friction wheel 63 and the second friction wheel 64. The upper end of the first gap corresponds to the money-sorting ramp 61, and the lower end corresponds to the red envelopes transported by the transfer device.

[0070] The first friction wheel 63 rotates clockwise and uses friction to convey the bottom coins forward. The second friction wheel 64 rotates clockwise and is mainly responsible for hitting the upper layer of money backward to ensure that only one coin passes through the first gap each time.

[0071] The coins passing through the first gap fall downward into the red envelopes that have been opened and transported by the transfer device.

[0072] To ensure the accuracy of the money-sorting quantity, the money-loading device further includes a money-sending device. The money-sending device is arranged between the money-sorting device and the transfer device and includes a money-sending motor 65 and a third friction wheel 66 and a fourth friction wheel 67 that are driven to rotate by the money-sending motor 65.

[0073] The third friction wheel 66 and the fourth friction wheel 67 are arranged opposite to each other and rotate in opposite directions.

[0074] Specifically, both the third friction wheel 66 and the fourth friction wheel 67 are located below the coin-sorting device. A second gap for the coins to pass through is left between the third friction wheel 66 and the fourth friction wheel 67, and the second gap is arranged corresponding to the first gap.

[0075] A bent baffle is correspondingly provided at the end of the coin-sorting ramp 61 for adjusting the movement direction of the coins passing through the first gap to the second gap.

[0076] The third friction wheel 66 rotates clockwise and the fourth friction wheel 67 rotates counterclockwise. Through the combined friction of the third friction wheel 66 and the fourth friction wheel 67, the coins can quickly pass through the second gap and enter the red envelopes that have been transported by the transfer device and whose mouths are open.

[0077] An infrared detection device is provided beside the second gap for detecting the number of coins passing through the second gap. When the number of coins passing through the second gap reaches a preset value, the infrared detection device sends a signal to the control device, and the control device stops the counting of the infrared detection device and the rotation of each friction wheel to stop the continued distribution and loading of coins into the red envelopes. Then the turntable 3 can rotate to transfer the red envelopes to one side of the sealing device at the next station to seal the red envelopes. When the second red envelope arrives, each friction wheel and the infrared detection device start working again to load money and count for the second red envelope.

[0078] In this embodiment, the rotation speeds of the third friction wheel 66 and the fourth friction wheel 67 are greater than those of the first friction wheel 63 and the second friction wheel 64, so as to widen the time gap and space gap for adjacent two coins to enter the red envelopes successively, making the counting of the infrared detection device more accurate and ensuring that a preset number of coins are loaded into the red envelopes.

[0079] The sealing device imitates the action of manually sealing the red envelopes by hand, and is provided with an ear-lifting mechanism and a sealing mechanism. The ear-lifting mechanism and the sealing mechanism are respectively located on both sides of the red envelopes transported by the transfer device.

[0080] The ear-lifting mechanism includes an ear-lifting servo 71 and an ear-lifting lever 72. The ear-lifting lever 72 is connected to the ear-lifting servo 71 and corresponds to the sealing ear of the red envelopes transported by the transfer device; the ear-lifting servo 71 is fixedly connected to the frame 1 for rotating the ear-lifting lever 72 so that the ear-lifting lever 72 slides over the side of the red envelope and lifts the sealing ear of the red envelope.

[0081] The sealing mechanism includes a sealing servo 73 and a hook-shaped lever 74. The hook-shaped lever 74 is fixedly connected to the sealing servo 73 and corresponds to the red envelope cover of the red envelopes transported by the transfer device.

[0082] The hook-shaped lever 74 corresponds to the rear side of the red envelope cover of the transferred red envelope and has a large rotation angle. During the rotation process of the hook-shaped lever 74, it can continuously press against the rear side of the red envelope cover, so that the red envelope cover is folded and rotated to be embedded in the red envelope ear.

[0083] Then, the hook-shaped lever 74 rotates in the opposite direction, and the ear-lifting servo 71 and the ear-lifting lever 72 are also reset to the initial state, ready for the sealing of the next red envelope.

[0084] In this embodiment, the hook-shaped lever 74 is a connecting rod and a pressure rod fixedly connected as one body, and two ends of the connecting rod are respectively connected to the sealing steering gear 73 and the pressure rod.

[0085] Then the turntable 3 can continue to rotate, and the sealed red envelope is transferred to the bottom of the turntable 3, ready for output of the finished product.

[0086] At this time, the opening steering gear 33 rotates in the opposite direction, the opening lever 34 releases the clamping of the red envelope, and the red envelope slides downward along the opening direction of the clamping part 32 to the finished product collection box 8 below.

[0087] like Figure 6 As shown, in this embodiment, an Arduino Mega2560 mainboard is used as the main control board. The red envelope taking device, the money loading device and the sealing device are each controlled by a UNO board. Under the coordination of the Mega2560 main control board, each UNO board can be deployed to synchronously realize the control of each device.

[0088] Working process:

[0089] Place a plurality of empty red envelopes horizontally on the inclined push plate 44, with the sealing ears of the red envelopes facing the inclined push plate 44 and the opening of the red envelopes facing the outside of the turntable 3. The inclined push plate 44 pushes a red envelope toward the turntable 3, and the suction cup 51 moves forward to suck the pushed red envelope, and then moves backward to make the red envelope stuck in the clamping part 32 of the turntable 3. The opening steering gear 33 of the clamping part 32 moves to clamp the two sides of the red envelope, so that the red envelope opens.

[0090] The suction cup 51 releases the red envelope, and the rotating disk 3 rotates 90° to transfer the red envelope to the bottom of the money loading device. The money loading device outputs a preset number of coins downwards and loads them into the red envelope.

[0091] The turntable 3 continues to rotate 90 degrees to transfer the red envelope to the side of the sealing device. The ear-lifting mechanism of the sealing device lifts the red envelope sealing ear, and the sealing mechanism folds the red envelope cover and presses it into the red envelope sealing ear.

[0092] The rotating disk 3 continues to rotate 90 °, and the red envelope is transported to a vertical downward position. The opening steering gear 33 releases the red envelope, and the red envelope just slides down into the finished product collection box 8 below.

[0093] Since the turntable 3 is provided with a total of 4 clamping parts 32, and each clamping part 32 is provided with a jaw servo 33. Every time the turntable 3 rotates 90°, the red packet wrapping robot can start a new red packet wrapping process. Therefore, 4 red packet wrapping processes can be carried out simultaneously, with high red packet wrapping efficiency, featuring full automation and high efficiency, and being at least 4 times faster than wrapping red packets by hand.

[0094] The above embodiments are the preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications made without departing from the spirit and principle of the present invention shall be equivalent replacement methods and are all included in the protection scope of the present invention.
