Rotation, and then the automatic rotation of detection device 100 is realized, with the rotation of detection device 100, its center of gravity constantly changes, substitution
In the prior art by changing position of the counterweight on weighing pan so that weighing pan has the scheme of different stress point, into
One step saves manpower, improves the efficiency of weighing sensor detection, simultaneously as what turntable 12 drove via dynamic equipment, institute
It is continuous rotation with detection device 100, detection device 100 is consecutive variations to the impetus of weighing pan, to have more
Big detection sample improves the precision of weighing sensor detection.
Optionally, detection device 100 further includes bearing (not shown), 13 one end of shaft connect via bearing with pedestal 11,
The other end is fixedly connected with pallet 121.Since shaft 13 is connect via bearing with pedestal 11, bearing can reduce shaft 13 and bottom
Frictional force between seat 11, and then reduce energy loss when turntable 12 rotates, detection device 100 is improved in automatic rotation process
In capacity usage ratio and reduce component friction the bring service life lose.
Second embodiment of the present invention is related to a kind of detection device 200 of weighing sensor, as shown in Fig. 2, second is real
It is roughly the same with first embodiment to apply mode, detection device 200 equally includes pedestal 11, and rotatably around rotation axis
Fixed turntable 12 on the pedestal 11, the center of gravity of turntable 12 are: first not on the rotation axis in place of the main distinction
In embodiment, turntable 12 includes pallet 121, the gravity block 122 being arranged on pallet 121, the center of shaft 13 and pallet 121
Position is connected, and the marginal position of pallet 121 is arranged in gravity block 122.And in second embodiment of the invention, shaft 13 and support
The marginal position of disk 121 is connected.So set, the center of gravity of pallet 121 is on the axis of shaft 13, therefore, with shaft 13
Continuous rotation, the center of gravity of pallet 121 constantly changes, and causes the center of gravity of detection device 200 constantly to change, so that detection device
200 weighing pan has different stress points, compared with the prior art in by changing position of the counterweight on weighing pan so that
The scheme that weighing pan has different stress points is obtained, manpower consumption is saved, improves the efficiency of weighing sensor detection, together
When, it can use regular shape, pallet cooperation shaft uniform in material constitutes detection device of the center of gravity not in shaft, structure
Simply, at low cost.
Optionally, gravity block 122 is additionally provided on pallet 121, gravity block 122 is arranged on pallet 121 and gravity block
122 and shaft 13 be located at the center of gravity two sides of pallet 121.So set, axis of the center of gravity of detection device 200 apart from shaft 13
Line is farther, so that the barycentre offset of detection device 200 is more during turntable 12 rotates, claims so as to detect
Whether accurate, improve the reliability of weighing sensor detection if weighing at larger range of stress point on disk again.
Third embodiment of the present invention is related to a kind of detection method of weighing sensor, as shown in figure 3, including following step
It is rapid:
S11: the detection device of weighing sensor is provided.

The structure of detection device in two embodiments can apply in present embodiment, and details are not described herein again.
S12: it is weighed using a qualified weighing sensor to detection device, the registration for reading qualified weighing sensor is made
For practical weighing.
S13: it will test device and be placed on the weighing pan of weighing sensor.
Specifically, in this step, the detection device is placed on the weighing pan and is located at the pedestal
The center of the weighing pan, so set, the center of gravity of detection device is in weighing pan with the automatic rotation of turntable 12
Heart position surrounding constantly changes, avoid " stress point of weighing pan be constantly in close to weighing pan side position and cause
Cannot detect whether the stress point of weighing pan is weighed at the other side accurate " the problem of, and then can more comprehensively measure
Stress point weighing pan everywhere when weighing result it is whether accurate, improve weighing sensor detection reliability.
It is understood that detection device is not necessarily placed on the center of weighing pan, as long as can change detection
The detection of weighing sensor can be realized to change the stress point on weighing pan in the position of centre of gravity of device.
S14: the weighing registration of weighing sensor described in turntable rotation process is read.
Specifically, in this step, at least 360 degree of the turntable are rotated, so set, can more comprehensively detect
Whether the weighing of the weighing pan is accurate, to improve the reliability of the weighing sensor detection.
In present embodiment, the turntable continuous rotation is driven, during the turntable continuous rotation, obtains work as in real time
The weighing registration of preceding weighing sensor.So set, detection device is to weighing pan since the detection device is continuous rotation
Impetus be consecutive variations, compared to discrete impetus, continuous impetus be bigger detection sample, improve title
Retransmit the precision of sensor detection.
It is understood that being also possible to when the turntable often turns over a predetermined angle, obtains primary current weighing and pass
The weighing registration of sensor.
Optionally, drive the opposite pedestal 11 of turntable 12 from turn by dynamic equipment (such as synchronous motor, asynchronous machine etc.)

Effect, details are not described herein again.
S15: if weighing registration meets preset condition with the difference actually weighed, determine weighing sensor qualification.
Specifically, in this step, in 12 rotation process of turntable, if weighing registration is permanent equal or poor with practical weighing
Value be less than preset threshold, then when illustrating the stress point of weighing pan throughout, the measurement of weighing sensor be accurately, therefore,
It can be assumed that being qualified for weighing sensor.
It is understood that during turntable 12 rotates, when the weighing registration of weighing sensor claims not equal to practical
It, can be by taking regulating measures (for example, the metal part of sensor body is rasped away a part with file) until at this when weight
The weighing registration at place is equal to practical weighing, and by adjusting finally making in 12 rotation process of turntable, weighing registration claims with practical
The equal or difference of weight perseverance is less than preset threshold, i.e. weighing sensor is qualified products.
It should be noted that it is practical to determine that the condition of weighing sensor qualification is not limited strictly to weighing registration permanent " being equal to "
Weighing is also possible to weighing registration and is less than preset range with the difference actually weighed, as long as meeting the relevant regulations of State Metrological Bureau
?.
