Description

Technical field

The utility model relates to the field of electronics, to equipment for warehouse storage, automated accounting and issuance of coils with electronic components for automated lines for surface mounting of electronic boards and can be used to automate warehouse storage, automated accounting and issuance of electronic components (resistors, capacitors, diodes, inductances, integrated circuits, etc.) supplied in tapes on standard coils, which are currently widely used in modern production of electronic boards on automated lines for surface mounting of electronic boards.

State of the art

Surface mount technology for electronic boards, abbreviated as SMT (from the English. Surface Mount Technology, or Surface Mount Technology (in Russian, - TMP), originated in the 1960s and after 20 years became widely used in the electronics industry.

With the development of automation (since the 2000s), surface mounting of printed circuit boards has come to dominate the production of electronic equipment.

Currently, the surface mount technology of electronic boards is the undisputed leader and it is difficult to find a modern device that would not be made using this technology.

The abbreviation and term SMD (from English - Surface Mount Device) means a component or device mounted on a surface.

Thus, SMD is understood as electronic components (electronic parts), and not technology as a whole.

The essence of SMT electronic board surface mount technology is to accurately install miniature SMD electronic components on the surface of the printed circuit board in the corresponding automated machines of automated printed circuit board production lines.

Compared to through-hole technology (the so-called TNT-Through Hole Technology), SMT surface mount technology of printed circuit boards has a number of main advantages:

there is no need to drill holes in the board for component leads;

it is possible to install components on both sides of the printed circuit board;

provides a high density of mounting of electronic components and, as a result, savings in materials and reducing the dimensions of finished products;

deeper automation of mass relatively cheap production of various printed circuit boards is possible;

reduced costs and improved quality and mass production of electronic products.

It is known that a semi-automated area for surface mounting of electronic boards usually provides assembly capacity of up to 3,500 electronic components / hour, a fully automated assembly area with a capacity of up to 10,500 sets / hour for the production of small / medium series of products, and an automated line for large-scale production with a fully automated assembly The site provides assembly productivity up to 108.000 comp/hour for the production of large series of products.

Thus, the use of SMT technology for surface mounting of electronic boards requires a very large number of various electronic components, which leads to high requirements for the conditions of storage, selection and prompt issuance of electronic components.

Since SMD electronic components (resistors, capacitors, microcircuits, etc.) are very small (often smaller than the size of a match head), the vast majority of SMD components are not marked, so it is easy to confuse elements with different purposes, since they all look very similar to each other.

Electronic components are fed into machines of automated surface mount lines by means of plastic carrier tapes with a standard width of 8, 12, 16, 24 mm, in which electronic components are placed in the corresponding recesses, and the tapes themselves are wound into coils, usually with a standard diameter of 178 (7 ") mm, 381 (15") mm, etc., which are usually placed directly next to automated surface mount lines or warehouses located near surface mount lines.

Electronics manufacturers usually use thousands of different parts (components) that they need to store, account for and, if necessary, promptly accurately issue, usually through many different coils with the required electronic components

A typical set of electronic parts of one simple printed circuit board usually consists of many (more than 50) different electronic component SKUs, so storing, promptly and accurately retrieving various required components from stocks for a variety of printed circuit boards is a technically very complex and time-consuming task.

Therefore, the accuracy of inventory and accounting, as well as the speed of issuing electronic components from storage sites, is of decisive importance both for the quality of printed circuit boards and for the efficiency of their production on automated surface mount lines.

In this regard, the task of increasing the efficiency of warehouse storage, automated accounting and prompt issuance of a large number of coils with a variety of electronic components for automated lines for surface mounting of electronic boards is relevant.

Known complex racks for storage and automated accounting of products, including n racks placed in closed cabinets and combined into a single information network associated with a remote server, made, for example, in the form of a personal computer. The racks on the shelves contain containers for storing various products (for example, spare parts and materials). The containers are provided with electronic labels that identify the type of products contained in them. Each rack is equipped with an information input panel containing a mobile label reader and designed to collect data on the state and movement of products in containers. The transfer of information to a remote server is carried out using a data transfer device. In addition, each cabinet is equipped with a door, on the outer side of which there is an electromechanical lock and an electronic reader for access control to the rack. The complex also includes an operator's electronic key [RU No. 65030, G06F 17/60, 2007].

The disadvantages of this device are associated with the collection of data on identifiable types of products in containers. To collect the specified data and transfer them to the information input panel, the operator must either enter this data manually using the remote control keyboard or also manually read the code recorded in the electronic tags and identifying the contents of this container using a mobile electronic reader. In both cases, this operation takes quite a lot of time, which leads to an increase in the total time of information transfer to a remote server and a corresponding decrease in the efficiency of automated product accounting. In addition, the participation of the operator in the product identification procedure using a mobile electronic reader does not exclude the possibility of operator error, which reduces the objectivity of automated product accounting.

A smart storage system for over 1,100 7-inch (178 mm) SMT spools is known, which is equipped with sensors and LED indicators, as well as Locator software, which includes a trolley; at least one splitter assembly installed inside the cart and providing a plurality of storage slots, each of said storage slots is sized, structured and configured to accommodate at least one SMT coil; a plurality of light guides each supported in a respective one of the plurality of slots, and each of the light guides includes a support structure that is designed and positioned to hold at least one of the SMT coils within the support structure, and each of said plurality of light guides is configured to movement between the nested position and the release position, which allows you to load the SMT coil into the slot and remove the SMT coil from the storage slot when it is in the released position; each of said plurality of light guides includes a first light entry point for allowing light entry from the two-color LED indicator when the light guide is in the retracted position, and a second light entry point for allowing light entry from the two-color LED indicator when the light guide is moved to the released position, and each of said plurality of light guides further includes an opposite outer end configured to light up when light is directed through either the first light entry point or the second light entry point, thereby visually indicating the location and state of the SMT coil. The operator simply scans the bar code on the spool and inserts the spool into an empty slot inside the cart, which uses a light guide in each slot to indicate the status of each slot using dual color LEDs. The system automatically reports the position of the part to its controller and then to the server via a Wi-Fi connection. To obtain parts, the user quickly enters a part number or a list of several parts into the computer and an LED lights up to indicate the location of each part in the cart. When the user selects parts, the system determines the part numbers that have been removed on the tablet or screen. The cart is mobile, ESD-compatible, 5 1/2 feet tall and has a footprint of less than 5% square meters, a fraction of the size of robotic towers commonly used in the industry, while still having five times the throughput [WO 2016138523 (A1), B65G 1/137; G06Q 10/08; H05K 7/00, 2016.09.01, priority according to US 201562121896 P 2015.02.27].

In this device, the light guide has two light entry points, one when the coil is in the installed position, and another light entry point when the light guide is moved to the release position, indicating that the SMT coil is removed from the slot in the spacer;

the cart includes a plurality of doors that can move to lock the SMT coils and prevent the removal of the SMT coils from the cart while allowing the light guide to function to indicate the status of the SMT coils, the doors having electronic/mechanical locks to lock the doors in the closed position;

trolley includes 14 rows (7 on each side) for storing surface-mounted reels (spools) in one package;

the cart is connected to the controller of the computer and/or tablet, which allows the computer or tablet to interact with the cart for the purposes of selecting, parts/components to be removed from the cart, and for keeping track of stock of parts/components in the cart;

the system calculates the approximate number of parts/components remaining on the SMT drum based on the diameter of the tape remaining on the drum, the pitch of the component on the tape, the thickness of the tape, and the intended usage at the time of release.

The closest in technical essence and the achieved result (prototype) is a complex of racks for storage and automated accounting of products, containing racks with shelves placed in closed cabinets and united in an information network connected to a remote server, each cabinet is equipped with a door with installed on it means access control to the racks, and on the racks there are containers with products and an information input panel containing a microcontroller connected via a data transmission device to a remote server, a keyboard and a display; and an operator’s electronic key, in order to increase the efficiency and objectivity of automated accounting of products on the racks, the rack is equipped with vertical partitions with the formation of a matrix structure of cells, in which each container is in one cell, and optical means for controlling the operator’s access to containers connected to the microcontroller, to to which the means of access control to the racks are connected [RU 95318 B65G 1/02 Published / 06/27/2010 Bull. No. 18 (prototype)].

At the same time, the optical means for controlling the operator's access to the containers are made in the form of the first and second light barriers located orthogonally relative to each other and containing emitters and radiation receivers located on opposite sides of the cabinet;

emitters of the first and second light barriers are placed with the ability to generate, respectively, the first and second sets of beams located in a common plane, which is in front of the containers;

the emitters of each light barrier are configured to generate parallel beams;

the rays in the first and second sets of rays are oriented orthogonally to each other;

light barriers include emitters and receivers of infrared radiation;

the data transmission device is located in the information input panel.

The disadvantages of RU 95318 (prototype), WO 2016138523 and most of the known analogues is the presence on the racks of longitudinal shelves with cells for coils with LED indication and the ability of the operator to determine the storage cell by scanning the barcode of the cell. At the same time, in most similar devices there is no automated control and accounting for the presence of a coil in a cell, since sensors for the presence of a coil in cells of known racks and storage facilities are usually not associated with accounting systems.

Implementation of the utility model

Proposed according to the claimed utility model, a hardware-software complex, a basket and a rack for storing and automated accounting of coils with electronic components of a surface-mounted line of electronic boards are intended for use in hardware-software systems for storing accounting and issuing electronic components (resistors, capacitors, diodes, inductances, integrated circuits, etc.) supplied in tapes on standard reels (tape and reel) for lines of surface mounting of electronic boards.

The software and hardware complex consists of two main functional parts (blocks):

a control module in the form of a software product deployed in a local control information network on an enterprise server, which provides integration of the complex with electronic components warehouse accounting programs, as well as enterprise ERP systems (for example, 1C) and controls the executive module,

and executive modules for storing coils of electronic components (storage objects), directly in which coils with electronic components are located in the corresponding cells of the corresponding sections of the baskets located on stationary or mobile racks.

The executive modules contain the proposed design of the basket - means of storing coils in the corresponding cells with means for monitoring the presence / absence and identification of coils in the cells, information indicators, control electronics and information communication lines with the control information network of the control module.

By means of the appropriate software, information about each accounted storage object (name, production date, type and number of components on each coil, etc.) is collected, processed and stored in the databases of the software and hardware complex on the enterprise server with data exchange with enterprise accounting systems (ERP systems).

The use of the software and hardware complex as a whole, using the proposed design solutions for executive modules, ensures the optimization of the enterprise warehouse in terms of automated accounting and issuance of electronic components in the process of manufacturing electronic boards on the lines of surface mounting of electronic boards using a large range of electronic components used, facilitating the search for the necessary units storage, minimizing the risk of errors due to human error.

The entire logic of the operation of the hardware-software complex as a whole is provided by the control module, the executive modules perform the basic functions of automated accounting, storage and issuance of coils with electronic components of the line for surface mounting of printed circuit boards in baskets and on racks of the proposed design.

The software and hardware complex as a whole can be flexibly adjusted to the needs of a particular enterprise without the need to reprogram executive modules, but only by modifying the control system software.

The software and hardware complex is easily scalable due to the use of the standard CAN interface (from the English Controlier Area Network - a network of controllers), which is a standard for industrial networks focused primarily on combining various actuators and sensors into a single network through serial, broadcast, packet data transfer mode.

The main structural units of the executive modules are the inventive racks with an original design, baskets for storing coils with electronic components for surface-mounted lines of electronic boards, in which storage places for coils with electronic components are formed in the corresponding cells of sections of the original design, as well as stationary and / or mobile racks of the original design. , on which the specified baskets are located.

Each basket for storing coils with electronic components via a bus with a CAN interface located at the base of the basket

connects to a single control information network and enterprise server;

periodically automatically polled by the server and reports its current state, which allows you to quickly receive information about the occupied / free compartments for storing coils with components

if necessary, receives commands from the server to turn on LEDs of the corresponding color in certain places and to generate sound messages

Baskets for storing coils with electronic components can be placed on stationary racks or on mobile racks in the form of movable carts.

Mobile trolleys can be powered by rechargeable batteries, the capacities of which are selected sufficient for at least two work shifts, and are equipped with a wireless WiFi interface with the ability to connect to a server via a local network.

During operation, each basket is periodically interrogated by the server through the corresponding communication lines and informs the server of its current state, which allows you to quickly receive information about the occupied / free compartments for storing coils with components and, if necessary, issue certain required coils, send commands to the corresponding baskets from the server to turn on LEDs of the corresponding color and / or to generate sound messages about the location of the basket with the required electronic components.

A characteristic feature of the proposed design of baskets for storing coils with electronic components of a surface-mounted line of electronic boards is the placement of coils in cells of sections with an inclined surface of the base and the possibility of pressing with their weight on movable, hinged levers fixed at the base of the cells, mainly vertically oriented in free cells with the possibility mechanical interface with elastic metal plates on the printed circuit boards of the bases of the sections in the presence of coils in the corresponding cells.

When placing coils with electronic components in the cells of the basket section, the corresponding levers deviate from a predominantly vertical position and act on the metal plates on the printed circuit boards of the sections' bases with the formation of gaps between the metal plates and the capacitive electrodes located on the printed circuit boards of the sections connected to measurement systems connected to their own turn to microcontrollers.

Basket section microcontrollers cyclically measure the capacitance of all electrodes over which metal plates are located

In the absence of coils with electronic components in the cells of the sections, the levers of the cells in the sections do not change their initial predominantly vertical position and, accordingly, do not deflect the metal plates, which leads to an increase in the capacitance of the electrodes.

In the presence of coils with electronic components in the cells, the levers deflect the metal plates, which leads to a decrease in the capacitance of the corresponding electrodes.

The excess of the measured capacitance of the electrodes above the specified thresholds means the absence of coils with electronic components in the cells of the sections.

A decrease in the capacitance of the electrodes below the specified thresholds means the presence of coils with electronic components in the corresponding cells of the sections of the basket.

The use of capacitive sensors for the presence / absence of coils in the cells of the sections provides reduced power consumption, as well as increased resistance to environmental factors.

Due to the fact that all control is provided by the software of the control module located in the local network of the enterprise, the software and hardware complex has the flexibility to adapt to specific tasks of the enterprise.

The use of - (from the English. Red - red, Green - green, Blue - blue) light guides allows you to indicate the state of specific cells in the basket in different colors, the need to act with specific cells, emergency and service conditions.

RGB LEDs are connected to microcontrollers and controlled by commands from the server, which allows you to flexibly change the scenarios for displaying information both for each cell for storing components, and in the corresponding section and for the entire basket.

In addition to the RGB LEDs in the cells, each basket can be equipped with audible alarms to draw attention to a specific basket in case of need for actions to install / remove coils of components, or in emergency situations.

In addition to separate RGB LEDs and sounders, a group of baskets can be equipped with beacons located above the baskets and designed to draw attention to individual storage areas to speed up the process of finding the required baskets and corresponding cells, and, if necessary, actions to install / remove specific coils with electronic components, or, respectively, the required actions in emergency situations

Usually, some of the cells in the baskets of the executive modules are free, some of the cells are filled with storing information about the available electronic components in the external database of the control module.

If it is necessary to remove a coil with a specific electronic component (or a set of coils with the required components) from the storage location(s), the control module issues a command to a specific executive module, while the storage location of the required coil is highlighted by an LED indicator, and the storage area is also highlighted, which is advisable when a large number of storage spaces.

The decision as to which particular component to retrieve may be made by inventory control systems, ERP systems, and/or the operator.

If it is necessary to place any electronic component for storage, the operator scans the barcode of its coil, after which it places the coil in any free cell with automatic storage storage.

The main structural unit of the executive modules is a basket for storage and automated accounting of coils with electronic components.

The basket is made with a predominant width of 1 m and is mainly recruited from 4 sections with a predominant width of 250 mm.

Sections can be either of the same or different types, but - each for coils of the same diameter.

Under the sections of each type (designed for coils of a specific size), separate electronic section boards (section board, SB) are used.

Section boards are connected by detachable connections and fixed on the base of the basket with fasteners.

One of the section boards in the basket (left Fig. 2) contains a power supply circuit, a CAN bus transceiver and connectors for connecting to it. This board is called the master board in the basket and is responsible for communicating through the basket bus and controlling both the sensors and indicators of this section and the sensors / indicators of other slave sections. The same board is responsible for the low-voltage power supply of the remaining section boards in the basket.

The rest of the section boards in the basket are slave boards and do not have a mounted interface to the CAN bus. The sensors and indicators of these boards are controlled by their electronics according to the commands of the electronics of the master board. Commands are received through the internal bus of the basket, which is built on a standard SPI interface.

The block diagram of the section board is shown in the drawings. A separate PCB topology is created for each type of section according to different sizes of coils. The circuitry of the circuit boards of the sections of all coil ratings is the same.

A characteristic feature of the proposed solutions is the use of distributed capacitive sensors as sensors for the presence/absence of coils in cells of sections.

Unlike commonly used Hall sensors or optical sensors, the use of distributed capacitive sensors to detect the presence / absence of coils in the cells of the sections provides lower power consumption and is not susceptible to the negative effects of electromagnetic fields, ambient light and dust.

The software of the control and executive modules is designed to be used to ensure the implementation of the commonly required functions of automated storage, accounting and issuance of electronic components on the lines of surface mounting of electronic boards, including, in particular:

tracking the location of all coils with SMD components;

address storage location of each coil;

automatic highlighting of the sector in which the desired coil is located;

highlighting sectors in the correct sequence, according to the sequence of installation in the SMD machine;

keeping track of the number of electronic components in each coil;

analysis of each production order and the appropriate selection of coils (one or more) with a sufficient number of components to complete the current task;

planning resources in accordance with production plans (for a week, for a month, for a year), control of the residual number of coils and components, as well as notification of the need to replenish stocks;

analysis of the availability of component coils (for several production lines). If, for example, a reel with components, and the system received several orders for it at the same time, the program issues a notification about this, prompting you to select the order in which the tasks are to be performed.
