Description
Technical field
The invention belongs to industrial sewing machine control system technical field.
Background technology
At present, the Sewing machines Integral type controller type that market occurs mainly contains: control system and motor integrated, directly and the head of sewing machine integrated design of installing, single sided board is independently installed; Control system and motor are independently assembled, the integrated design of installing with head of sewing machine respectively, panel and control system integration one.
There is shortcoming in the above-mentioned type, although its controller architecture realizes integrated design, but it is too much to expose connector, and between plate, connecting line is many, and heat concentrates on internal system, affect product stability, and this construction profile is excessive, very unsightly, Material Cost is too high simultaneously, be unfavorable for transport and install, greatly reducing production work efficiency.
Commercially available controller is many to be made up of more than two pieces circuit boards, has following reason:
One is that on controller circuit board, components and parts are too much, needs larger space to lay, and outer cover finite volume, limit the area of single circuit board;
Two is that controller includes multiple power device, each power device must with separate heat sinks, existing heat radiating fin structure as shown in Figure 3, fin is by being connected to the base plate of power device and forming perpendicular to some fins of base plate, because the base areas of fin is limited, therefore this kind of fin mainly relies on fin total surface area to dispel the heat, so fin must have very large height, and this kind of fin is all directly fix on circuit boards, therefore, the space requirement of fin limits the area of circuit board, be difficult to multiple power device close-packed arrays simultaneously,
Three is that commercially available controller connector is mostly exposed is connected with circuit board by connecting line on die casting aluminium base plate or outer cover, and connector also exists larger space requirement, limits simplifying of board area.
Summary of the invention
For above-mentioned the deficiencies in the prior art, the invention provides a kind of industrial sewing machine integrated controller, this controller adopts single circuit board structural design, abandon traditional integrated controller outer cover and die casting aluminium base plate fastens, circuit board is fixed on die casting aluminium base plate and using it as the frame mode of fin, adopting is installed on outer cover by circuit board, adopt independently fin to be welded on circuit board or use outer cover heat radiation, finally fastening with protective plate and outer cover the effect playing sealing and dustproof; This structural design, reduces Material Cost greatly, without connecting line between plate, unique Duct design, thermal diffusivity is better, and stability is higher, and product appearance is more exquisite, and thickness is thinner, give produce, that transport brings is more how convenient.
Concrete technology path of the present invention is:
Industrial sewing machine integrated controller, comprise outer cover, control system and motor, control system is primarily of the circuit board and the connector composition that comprise some power devices, it is characterized in that described integrated controller comprises one piece and fastens protective plate for sealing and dustproof with outer cover, described control system only comprises one piece of circuit board be vertically fixed between outer cover and protective plate, circuit board comprises one group of compact arranged power device, the affixed integrated radiating sheet of this group power device, this integrated radiating sheet is one piece of metal base plate with the short groove of heat radiation, this metal base plate comprises at least one sidewall turned down inside circuit board.
Described protective plate surface has at least one air vent, and the handwheel through hole on this air vent and outer cover and the louvre on outer cover sidewall form an air channel.
Described power device leaves the installing hole for affixed fin.
Described connector is built on circuit board, and protective plate arranges socket.
Described connector is installed on protective plate.
Controller of the present invention adopts single circuit board structural design, and structure optimization, volume is little, and thickness is thin, and cost is low, greatly meets the demand of client.
Single plate structure advantage:
1. reduce rat tail between plate.Between plate, rat tail is one of reason of system instability, and between wire harness, signal intersects mutually, mutually disturbs, and adopts single plate structure effectively to reduce connecting line between plate, and by the less signal cross of placement-and-routing, strengthening system stability, reduces wire harness cost;
2. reduce connector.Between plate, the connection of signal must use mother daughter board connector.Connector is one of major reason causing control system instability.Easily loose contact is there is thus influential system stability by system vibration influence in connector when system cloud gray model.Use single plate structure instead, the stability that minimizing connector effectively can increase system reduces costs simultaneously;
3. adopt single plate structure to simplify mounting process.Many board mounting structures have sequencing when mounted, and mounting process is complicated, and in installation process, lime light is many, test test point is many, and single plate structure solves this kind of technological problems, installs simple, easy to detect, is convenient to large-scale production.
Controller circuit board of the present invention is independently installed on outer cover, and production technology is improved greatly, enhances productivity.
1. directly utilize electrical motor of sewing machine cover as the outer cover of controller, circuit board is arranged on outer cover simultaneously, avoids the installation blind spot occurred in production and assembly process, cause product bad, greatly simplify assembling process, this outer cover can make plastics or aluminium material according to demand simultaneously;
2. adopt this structure, connector not only can be arranged on outer cover, connector can also be simplified, connector is built in system, protective plate reserves socket or directly connector is arranged on protective plate, broken away from the limitation that old Controller gain variations is subject to connector position restriction, system more rationally, stable, hommization, attractive in appearance;
Controller of the present invention adopts the heat radiation of integrated radiating sheet.
1. traditional heat of system motor for motor and base plate one and the heat of power device concentrate on base plate, be unfavorable for heat radiation, adopt separate heat sinks, the heat of power device and motor heat are separated, buying of motor is hotly obviously better than electronic device, be conducive to protecting electronic device, improve the stability of system;
2. motor is separated, system uses the system of die casting aluminium base plate heat radiation, for ensureing that the device pin production that do not stress is taked first to assemble rear welding procedure, manual welding efficiency is in process of production low, easily cause bad, this, with separate heat sinks, is welded by machine, faster production, improves yield rate;
Controller of the present invention adopts protective plate to protect controller inside, has unique Duct design simultaneously;
1. this structure is existing to automatically controlled protective action, avoids dust, greasy dirt to the infringement of controller; Simultaneously at the Position Design air vent that protective plate is special, by forming a unimpeded air channel with the air vent of outer cover, between the air holes of two ends, forming air pressure during hand wheel rotating, finally forming air-flow, realize the gas exchanges that controller is inner and extraneous, reach the object of heat radiation.
Control system height of the present invention is integrated, cost-saving, and volume is little, convenient transportation, and product wire harness is few, improves performance and the stability of product, simple installation, good looking appearance.
