The utility model is characterized in that pressure-resistant, insulating and sealing layers are covered on electrical components in the electronic circuit, a digital display system and a sensing system of the weighting apparatus, a stabilizing power supply (including an accumulator) is arranged outside a weighting body, a supply voltage is direct current which is under 36V, the weighting body and the stabilizing power supply are connected by a waterproof conductor or a waterproof conductor with a plug and a socket, and an anti-corrosion layer is adsorbed on the surface of a sensor. The utility model is suitable for weight counting weighers, price counting weighers, count weighers, bar code weighers and special weighers.
Description
The utility model relates to a kind of electronic weighing device, particularly a kind of waterproof and dampproof electronic weighing device.
Existing electronic weighing device generally partly is made up of pressure transducer, electronic circuit, digital demonstration, stabilized voltage supply, bearing plate, title body etc.Wherein pressure transducer, electronic circuit, digital demonstration, stabilized voltage supply partly are mounted on bearing plate, claim organically to be linked together by printed circuit board (PCB) in the casing of body formation, realize function of weighing, and supply voltage is a 220V standard civil power.Such electronic scale especially at processing of aquatic products sales industry cisco unity malfunction, claims the easy corrosion of pressure transducer in the body, and Danger Electric shock risk is often arranged when civil power cuts off the power supply and under the wet environment condition.
The purpose of this utility model provides the electronic weighing device of a kind of waterproof, protection against the tide, corrosion protection, safety.
Outward appearance of the present utility model, structure, electronic circuit are similar substantially to the ordinary electronic weighing device, comprise parts such as pressure transducer, electronic circuit, digital demonstration, stabilized voltage supply, bearing plate, title body, be characterized in: cover one withstand voltage, insulation, sealant on the electric elements in described electronic circuit, digital display system and the sensor-based system; Stabilized voltage supply (comprising accumulator) is located at and claims that supply voltage is below the direct current 36V beyond the body, claims between body and the stabilized voltage supply to link with the water proof wire of water proof wire or band plug, socket; Sensor surface absorption one deck lumarith; Thereby realize waterproof, protection against the tide, corrosion protection, purpose of safety.Be applied to encapsulant of the present utility model and be dielectric voltage withstand more than 36V, temperature is not melting more than 60 ℃ at crackle not below 0 ℃, and the time is anti-aging more than half a year, do not come off, as silicon rubber, resin glue etc.; The thickness of seal coating is more than 0.50mm.
The utility model has the advantages that: (1) power supply is claiming external body and is being the safe voltage below the direct current 36V not have the danger of electric shock.(2) but the dual-purpose and holding storage battery of power supply AC and DC, the operate as normal but the short time has a power failure.(3) claim the body internal circuit to seal processing, can be under any wet environment operate as normal, also can be immersed in the water and work.(4) sensor surface carries out the corrosion protection processing, is not easy corrosion.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described:
Accompanying drawing 1 is the structural representation of the utility model embodiment
Accompanying drawing 2 is the circuit board encapsulation process synoptic diagram of the utility model embodiment
Accompanying drawing 3 is the sensor encapsulation process synoptic diagram of the utility model embodiment
In embodiment of the present utility model, encapsulant has been selected silicon rubber for use, and this insulated with material is withstand voltage more than 36V, and temperature is not melting more than 60 ℃ at crackle not below 0 ℃, and is anti-aging, do not come off the time more than half a year.When each circuit board of the present utility model being carried out encapsulation process with silicon rubber, can and connect all the electric elements on the circuit board and cover, also can the local part that only covers the short circuit of making moist easily, present embodiment has adopted the scheme of whole coverings, and (referring to Fig. 2, among the figure: 1 is water proof wire; 2 is the insulated enclosure material; 3 is wiring board; 4 is electric elements).When pressure transducer being carried out encapsulation process with silicon rubber, the only local part that covers the electric elements place, (referring to Fig. 3, among the figure: 1 is sensor to all the other sensor surfaces with chemical process method absorption one deck lumarith; 2 for being electric elements; 3 is the insulated enclosure material; 4 is water proof wire).Each electric component directly connects with water proof wire each other, but for unloading conveniently by mounting or dismounting, the on line between two parts can disconnect, after its joint connects with the method for plant propagation with cutting or welding process, the encapsulating method of butt junction is analogous to the sealing to circuit board, and the thickness of seal coating is all more than 0.50mm.Each parts with claim to adopt the universal machine method to connect between the body.The power lead of waterproof connects the external dedicated stabilized voltage supply through a waterproof plug, this stabilized voltage supply can connect accumulator, when the civil power short time has a power failure can operate as normal, thus realized that (referring to Fig. 1, among the figure: 1 is stabilized voltage supply for the function of weighing of waterproof, protection against the tide, corrosion protection, safety; 2 is waterproof plug; 3 is water proof wire; 4 is bearing plate; 5 for claiming body; 6 is preceding display board; 7 for claiming the angle).Profile of the present utility model can be square, circle and polygon; The scope of weighing is 0.01g～1000Kg; The scope of application is meter weight, valuation, counting, bar code and extraordinary special-purpose weighing apparatus.
Claims (3)
1. waterproof and dampproof electronic weighing device, comprise pressure transducer, electronic circuit, digital demonstration, stabilized voltage supply, bearing plate and claim body, it is characterized in that: cover one withstand voltage, insulation, sealant on the electric elements in described electronic circuit, digital display system and the sensor-based system.
2. a kind of waterproof and dampproof electronic weighing device according to claim 1 is characterized in that: stabilized voltage supply comprises accumulator and is located at and claims beyond the body, claims between body and the stabilized voltage supply to link with the water proof wire of water proof wire or band plug, socket.
