Description

An exchange manipulator

Technical field

The invention relates to the technical field of unmanned shop equipment, in particular to an exchange manipulator.

Background technique

In the first store, there were people who sold goods. There was a counter. Tell the salesperson what you wanted to buy. The salesperson took what to buy. The sales were done on the counter. Customers could not enter the store. Later, it became a hypermarket. In supermarkets, people can go in to choose items, come out and pay again; then some people open unmanned stores, let customers go to choose the goods and then pay by themselves; in some stores, what induction labels are attached to the goods can be automatically sensed Customers pay for the goods and their prices. At present, a kind of vending machine has appeared on the market. This kind of vending machine can only sell a few commodities, that is, a few or a dozen kinds, which can not meet the needs of people's daily life. There is also an automatic vending machine in the hospital. The medicine machine can only take a few medicines, and it cannot be called an unmanned store at all.

In the first store, a salesperson took out the goods to trade on the counter. It would be nice to replace the salesperson with a robotic device, so that an unmanned store could be opened. Now that the technology is very advanced, it is very easy to be such a manipulator. This manipulator equipment is extracted from the SMT equipment (that is, the placement machine in the electronics factory). The following briefly introduces an SMT equipment:

SMT equipment is to take a variety of different materials, mainly some small electronic components, some are very small, and the component 201 is only one millimeter. Take these small materials and place them on various positions on the motherboard. I have been to a high-temperature tin furnace and wait until the surface is covered with tin. After the temperature drops, these electronic components are firmly fixed on it. Of course, the position of each material and the position to be attached to the motherboard must be set in the computer in advance. And the order of posting is also set in advance. Each motherboard has hundreds or even thousands of electronic components, SMT equipment can accurately pick up these and put them where they should be. The size of this equipment has a very high accuracy, which can reach one thousandth of a millimeter. Naturally, this equipment is very expensive. The expensive one is 2 million yuan per unit, and there are also low precision requirements, and the cheap one has 20,000 yuan per unit. . This device mainly relies on the servo motor to realize the conversion from a numerical parameter (only a numerical value is input in a computer and other equipment) to a distance (the manipulator moves such a distance), that is to say, when a numerical value to be moved is given, The servo motor will move as required until it reaches the destination. This method is also a many-to-many method, that is, multiple materials are picked up at the feeding place and sent to different positions on the main board. Because there are hundreds or thousands of parts on a motherboard, the total time to paste these parts can't be too long, so when the placement machine attaches components, the robot moves very fast, so fast that the robot is almost invisible The movement of this equipment is also very efficient. There is also a kind of mechanical equipment made of servo motors, injection molding machines. This injection molding machine does not have a cylinder, but is driven by a servo motor. This injection molding machine is more precise than that with a cylinder. The injection volume of an injection molding machine is one gram. One hundredth of the value can be accurately obtained. When adjusting various parameters, each time a value is set, the motor will move to a different position according to the value. The daily elevator is also driven by a servo motor. Each time you press a number button , The elevator will stop at the corresponding floor. This is also an example of converting the number to a different position, but the parameter of the elevator movement position is changed to the floor.

This servo system is an automatic control system that enables the output controlled quantity of the object's position, orientation, state, etc. to follow the arbitrary change of the input target (or given value). Servo mainly relies on pulses for positioning. Basically, it can be understood that when the servo motor receives 1 pulse, it will rotate the angle corresponding to 1 pulse to achieve displacement. Because the servo motor itself has the function of sending pulses, every time the servo motor rotates At an angle, a corresponding number of pulses will be sent out, which echoes the pulses received by the servo motor, or is called a closed loop. In this way, the system will know how many pulses have been sent to the servo motor, and how many pulses have been received at the same time. That is to say, it transmits the signal to the system at any time, and at the same time corrects its operation with the signal given by the system, so that it can control the rotation of the motor very accurately, thereby achieving precise positioning, which can reach 0.001mm. The rotor inside the servo motor is a permanent magnet. The U/V/W three-phase electricity controlled by the driver forms an electromagnetic field. The rotor rotates under the action of this magnetic field. At the same time, the encoder of the motor feeds back the signal to the driver, and the driver matches the target according to the feedback value. Compare the values and adjust the angle of rotation of the rotor, so the accuracy of the servo motor is determined by the accuracy of the encoder (number of lines), which can be determined according to the needs of the store.

With the principles and methods of this manipulator, the size is not a problem. At the same time, according to the many-to-many method, each item in multiple positions can be picked up, and it can be placed in any of multiple different positions. Go up, you can be sure to apply this kind of manipulator to the unmanned store. This SMT equipment has been used in the electronic industry world for decades, and the technology is already very mature. There is no problem with electronic components that are so small, and there is no problem with this daily necessities with electronic components 100 times the size, so this kind of servo motor manipulator is no problem when used in unmanned shops.

You only need to optimize the patch part of the SMT equipment to design a manipulator for unmanned shops. The accuracy of this manipulator is much lower than that of the SMT placement machine injection molding machine. Take a product without error. Nothing more than a centimeter. Companies such as JD.com and SF Express use so many small robots to run back and forth when sorting packages. It is also known as a major innovation in China on the Internet. In fact, using this robot is more suitable, lower cost, and simpler. After the customer scans the QR code affixed to the product or enters the information of the purchased product through other devices, the controller in the store system will receive the product information and transmit the product information to the robot in the storage area, waiting for the customer After payment, the robot will take the product placed in the storage area according to the designated position of the system (the product in the storage area may not have a QR code) to the designated pick-up point of the system, and the customer can use the mobile phone tablet and other devices The door of the pick-up area is opened, and the purchased goods can be taken away.

The unmanned store that uses this manipulator is divided into an operation area and a storage area in space. The operation area is mainly for storing the goods to be sold for customers to choose to scan the code. The storage area is mainly for storing the sold goods, the storage area and The operation area is separated. Customers can only view the goods in the operation area, scan the code, and cannot enter the storage area. When the customer sees the product in the operation area and wants to buy it, he can use his mobile phone or other scanning device to scan the QR code of the store affixed to the product. The information of the product that wants to buy is through the network (3G, 4G, 5G, Wifi, BT, etc.) are transmitted to the controller of the store, and the controller uses the servo motor manipulator to pick up the goods and put them at the pick-up place. The customer can pick up the goods at the pick-up place. Because the precision requirements of this manipulator may not be high, the accumulated error may be a bit large after many runs, so it is necessary to specify a picking point as the basic origin. When the manipulator moves to this point, the manipulator system will automatically return the position information. Zero, everything is calculated from scratch, and the error is cleared. Some stores have two operation areas, because the goods in the storage area are arranged in rows, and both ends of a row of shelves can be set as an operation area. The outline of the store is shown in Figure 1. Note 1 indicates the pick-up location, 2 indicates the shelf, 3 indicates a pick-up robot with its own shopping box, 4 indicates the exchange manipulator, and 5 indicates the exchange shopping box hanging rod assembly. It can be seen that the unmanned store system consists of these parts, the operation area (the goods in the operation area must be affixed with the QR code and price of the store), and the storage area (the goods in the storage area are placed strictly according to the entered position), Manipulator, fetching place, controller, etc.

The merchandise displayed in the operation area also has a certain degree of attention. The daily necessities that consume more should be placed in a conspicuous place, and the less common merchandise can be placed in the corner and placed clearly according to types, such as paper products. To put them together, the beverages are also classified into a large category, put together separately, and the food category is also separately placed in another place. Individually expensive ones can be placed in a few more identical ones, so that multiple customers can scan the code, etc. To classify and place, as shown in Figure 2, in the comment, 11 represents the line identification (row number), 12 represents the column identification (column number), 13 represents the QR code, and 14 represents the product label. There are multiple pick-up locations in the operation area, which can be used by multiple people to shop at the same time. Basically, the bottom layer below the operation area is the pick-up location. After each customer scans the code on the mobile phone and pays, the system will notify via the mobile phone Where the customer picks up the goods, when the customer arrives at the pick-up place, he can turn on the pick-up place in the switch setting of the mobile phone, and then the purchased goods can be gone. The reason why you want to set the switch of the pick-up place in your mobile phone is because you are afraid that the customer's goods will be taken away by other customers. The switch at the pick-up location is controlled by a solenoid valve powered by the system. When the door at the pick-up location is closed, the solenoid valve will block the pick-up location and cannot be pulled out. You can only open the pick-up location by clicking on the customer’s mobile phone. The solenoid valve Withdraw it, the customer can pull out the pick-up place to take away the goods. In addition to shopping with a mobile phone scan code, customers can also shop through other shopping devices in the operating area. This device is connected to the main controller in the store, and the goods purchased through this device will also be transmitted to the main controller. Finish shopping. This device is called a shopping device, and customers use it to purchase goods.

The merchandise in the storage area should be placed strictly in accordance with the position entered in the system. You can set each merchandise position in the system first, and then place the merchandise. Each merchandise has one or more storage locations. The system entry location is The robot hand takes the position of the product. Every time it gets information, the robot hand takes the product. The robot hand only takes the product according to the location. The robot itself does not distinguish the type of the product. The product placed here is the product; you can also put the product first. Place the product, and then input the position of the product accurately into the system. When inputting the product location, you can first calculate and measure the value according to the coordinate system, and then enter it in the computer, or you can directly move the robot to the product. Location, press the button to record the location, scan the code of the product at this location and enter the type of the product, so that the relationship between the product and the location can be established, which is easier than inputting from a computer. The reason why you have to enter the location of the product into the system first is to preprocess these values (product location coordinates) in the controller. Later, when you buy a product, you only need to enter the product information (this information can be considered It is a code, number, and no longer the coordinate information of the location, just like making a bottom software), no need to enter the coordinate location information of the product. This makes a conversion, and shopping is much easier for customers. For products with a shelf life, the storage of the products should be in order, distinguishing the products that are placed first and the products that are placed later, especially when replenishing goods, it must be done to separate the first-in and later-in products. First in first out. The slot for placing the goods in the storage area can be made into a sloped slot, allowing the goods to automatically slide and supplement to the position of the manipulator. Mineral water and the like can automatically slide, but light products such as paper towels cannot automatically slide. Add a heavy press block to the paper towel to make it slide automatically, as shown in Figure 3, where 15 in the note is the press block, 16 is the ramp groove, 17 is the horizontal part in front of the tank, and 18 is the front of the cargo tank Part of the baffle. In this way, the store can spend an hour or so every day to replenish the goods, or it can take an hour or so to replenish the goods in a few days. If the customer has any questions, they can come to the store to find the staff according to the replenishment time stated in the notice. For issues such as returns, large stores can also arrange for a person to be on duty during a certain period of time (such as 8:00-18:00 during working hours) to deal with exceptions and return issues. Manipulators should also be overhauled regularly, such as adding lubricating oil, etc., especially pay attention to regularly replacing those components that are easy to wear.

The key equipment in this unmanned store is the picking manipulator 3 with its own shopping box, a three-dimensional manipulator, as shown in Figure 4. The fixed horizontal rail 19 is sometimes two or one, and L1 represents the moving horizontal rail 21 of the manipulator. The maximum distance that can be moved on the fixed horizontal rail 19, L2 represents the maximum distance that the moving vertical rail 24 of the manipulator can move on the moving horizontal rail 21, and L3 represents the manipulator terminal grasping mechanism 31 on the moving vertical rail 24 The maximum distance that can be moved.

The shopping box rotating motor 63 is equipped with a shopping box hanging rod 65, and the shopping box hanging rod 65 is equipped with a shopping box solenoid valve. 61. A shopping box 60 is installed on the shopping box solenoid valve 61.

The picking manipulator 3 with its own shopping box is equipped with a moving vertical rail rotating motor 22, which mainly makes the terminal grasping mechanism 31 of the manipulator rotate when picking up the goods and putting the goods into the shopping box 60, or directly into the picking place 1, or used to switch the gripping mode of the robot terminal gripping mechanism 31. The shopping box solenoid valve 61 is mainly used to turn the shopping box 60 and pour the goods in the shopping box 60 into the picking place 1. The shopping box rotation motor 63 mainly adjusts the direction of the shopping box to make it convenient to pour the goods into and take.物处1.

Generally speaking, the fixed horizontal guide rail 19 is fixed on the ground or on the wall, usually at the top or bottom, to determine the starting position of the manipulator movement, as well as the X-axis and Y-axis directions of the manipulator's horizontal movement. The vertical direction is The Z axis is now established. Create a coordinate system, and then input the coordinates of each product in this coordinate system (3D coordinates) into the system. These coordinates must be within the range of the robot's movement and cannot be reached by the robot. Sometimes in order to save space, the shelf height reaches the roof. The terminal gripping mechanism 31 of the manipulator is divided into a clamping type and a suction type. The clamping type is to use the grips of the manipulator to grip the goods. The suction type is to suck the goods by negative pressure. These two types should be used according to different goods. Water, beer, etc. should be clamped, and instant noodles, biscuits, etc. should be sucked. When the main controller receives the shopping information, the manipulator controller 30 will issue instructions to the servo drives of each motor, and each motor will immediately rotate. In Figure 4, the X-axis movement of the gripping mechanism 31 of the manipulator terminal is determined by The motor pulls the moving vertical rail to move on the moving horizontal rail 24. The Y-axis movement of the robot terminal grasping mechanism 31 is achieved by the motor pulling the moving horizontal rail to move on the fixed horizontal rail 19. The robot terminal grabs The movement of the mechanism 31 in the Z-axis direction is achieved by the motor pulling the robot terminal grasping mechanism 31 to move on the moving vertical guide rail 24. By moving in these three directions, the robot terminal grasping mechanism 31 can place the goods. Move with full coverage in space, you can reach the placement position of the goods, take the required goods and send them to the shopping box, and then to the pick-up place; the moving vertical guide rail 24 of the manipulator moves vertically. The guide rail rotation motor 22 is used to switch between the gripping type and the suction type; there is a gripping solenoid valve 51 in the gripping type clip assembly 26, which realizes the gripping and loosening actions, the clip solenoid valve 51 and When the clamp is connected, the clamp solenoid valve 51 will expand or close, and the clamp will be opened or closed; there is a suction nozzle solenoid valve 44 in the multi-chamber negative pressure suction head assembly 23, which is used to generate negative pressure suction and release the negative pressure loosening action. When the suction nozzle solenoid valve 44 expands and contracts, the product and the multi-chamber negative pressure suction nozzle assembly 23 form a closed space. As the suction nozzle solenoid valve 44 stretches, the closed space becomes larger and the pressure in the closed space decreases. Adsorbed on the multi-chamber negative pressure suction head assembly 23, the functions of these solenoid valves can also be replaced by pneumatic cylinders to realize the suction and clamping actions.

After the customer scans the code, a connection or interface is opened on their mobile phone, and information such as the type, quantity and price of the goods to be purchased in the shop appears. After the customer chooses, the next step is to continue to buy or pay, and wait for the customer to buy it. When you need the goods, you will pay the bill, and you will be prompted whether to pay by WeChat or Alipay or other methods. After the selection is made, the payment will be deducted from it, and then the customer will be prompted to the number of pick-up locations for the goods you bought. After you get to the pick-up place, the system prompts the customer that you can open the door of the pick-up place, and the customer clicks on the phone to open the door of the pick-up place to take away the goods they bought. After the customer takes the product, the pick-up point automatically returns to its original state. Each order is only brought to one pick-up point. If a customer purchases too much or of different sizes, they can be divided into several orders for processing.

When the picking manipulator 3 with its own shopping box receives the information from the main controller, that is, the order, first analyze the order of picking, so that you can save some wasted distance and use the most economical distance to complete The task of fetching, because the fetching manipulator 3 with its own shopping box has a shopping box 60, after you get a product, you put it in the shopping box 60, you can go directly to take the next product, instead of taking the one you have already got After putting the goods in pick-up place 1, come back and take another product. First, analyze the picking sequence, that is, the picking manipulator 3 with its own shopping box, and the controller 30, find the one with the smallest distance to be taken by the picking manipulator 3 with its own shopping box. The program is generated as the retrieval manipulator 3 with its own shopping box as the retrieval execution program this time. The generation of this manipulator motion program is that the manipulator controller 30 first optimizes the order of taking products to find the order of the smallest path, and then this sequence plus the instructions of each moving component becomes a motion program. It can be seen that the execution program of the fetching manipulator 3 with the shopping box in the store is automatically generated by the customer's shopping order and is executed only once.

In the storage area, the storage shelves 2 are arranged in rows. The manipulator is placed above the store storage shelves 2. The moving horizontal guide rail 21 of the manipulator is set above the storage shelves 2, and multiple storage shelves 2 can be taken. The manipulator moves back and forth between the shelves, so both ends of the fixed horizontal rail 19 of the picking manipulator 3 with a shopping box can be provided with an operating area, and picking point 1 can be set for customers to use. The effects of both sides are the same, so there will be twice as many fetching points. In the operation area, you can also make some showcases to recommend newly arrived products, newly developed products, and promotion of discounts to customers. In the system, how many commodities are taken at each location and how many such commodities are kept are updated in real time. This system can be mixed with other systems. If the moving horizontal guide rail 21 of the manipulator is arranged under the storage shelf 2, the manipulator can only pick up the goods of two storage shelves 2, and cannot pick up goods from more than three storage shelves 2.

The manipulator used in this shop is different from the manipulator used in industry. The manipulator used in industry generally has a fixed position for taking objects, and the positions of placing objects are in a certain order, or the positions of taking objects are placed in a certain order. The location is fixed, but the store's robot fetching position and placing position are not fixed, but change according to the customer's requirements, and the placement of items is in a certain order. The action of the industrial manipulator is repeated after each setting, and has repetitiveness. One action mode can be done for several days, months or years, but this manipulator is different. Each action may be different from the last time, or the same , Its action is determined by the type of goods purchased by the customer. As long as an order is different, its action will be different. Each order is a motion program, and each order only performs one operation. It can also be said that the robot operates every time the order is paid. once. The generation of this manipulator motion program is that the robot controller first optimizes the order of taking the goods to find the order of the smallest path, and then this sequence plus the instructions of each moving part becomes a motion program. The key is that customer orders must be digitized, which can be transferred to the robot controller 30 in a timely manner to form a program. At the same time, the merchandise placement in the warehouse must also be digitized, and the type and location of the merchandise must be matched and input to the robot control. In this way, with digital input, the robot can accurately get the goods according to the digital order. The fixed horizontal guide rail 19 of the picking manipulator 3 with its own shopping box, the storage shelf 2, the goods on the shelf, the picking point 1 and the second guide rail 66 of the exchange manipulator 4 should be fixed to each other. The relative position of is fixed, and the picking parameters of the picking manipulator 3 with the shopping box will not change, so that each manipulator can accurately perform the task. Generally, the relative positions between the pick-up manipulators 3, storage shelves 2, pick-up place 1, etc. with their own shopping boxes are locked and fixed with iron bars to achieve standardization. The data in multiple stores should be the same for easy management and operating.

Such a store has many advantages: 1. It can save manpower and hire fewer employees. 2; Can sell goods seven days a week, and sell goods 24 hours a day. 3; Management costs can be reduced, because employees are lazy, etc., which greatly reduces management costs in this area. 4; You can decorate some stores less, which greatly saves the cost of decoration. 5; You can turn on the air conditioner only in the operating area, saving costs. 6; Can greatly save space, the storage area can be more densely stacked. 7; Can save customers shopping time. 8; You can set up a lot of pick-up locations, so you don't have to wait in line to pay for shopping, and this bottleneck disappears. In addition, unmanned stores can easily be standardized and managed.
