DETAILED DESCRIPTION

[0031] The following will be described in detail below with reference to the accompanying drawings Figures 1-3 The application is further described in detail.

[0032] The embodiment of the application discloses a milligram weight calibration device with a protection function. Figure 1 and Figure 2 A milligram weight calibration device with a protection function comprises a base 1, a moving assembly 2, a weighing table 3 and a supporting table 4, wherein the moving assembly 2, the weighing table 3 and the supporting table 4 are all arranged on the base 1. The weighing table 3 is provided with an electronic scale 31, the supporting table 4 is provided with a supporting seat 41 for placing weights, and the moving assembly 2 is provided with a suction cup assembly 5 for sucking the weights on the supporting table 4. The moving assembly 2 controls the movement of the suction cup assembly 5 to move the weights sucked by the suction cup assembly 5 to the electronic scale 31 for detection.

[0033] Referring to Figure 2 and Figure 3 The suction cup assembly 5 comprises a connecting pipe 51 and a suction ring 52, the connecting pipe 51 is connected with the moving assembly 2, the connecting pipe 51 is connected with a gas pump, the suction ring 52 is connected with the connecting pipe 51 through a connecting assembly 6, and the suction ring 52 is provided with a flow equalizing disc 53 at an end away from the connecting pipe 51, and the flow equalizing disc 53 is provided with a plurality of flow equalizing holes 531.

[0034] The moving assembly 2 comprises a first linear module 21 and a second linear module 22, a support is fixed on the base 1, the first linear module 21 is arranged on the support, and the first linear module 21 is arranged in a horizontal direction. The second linear module 22 is arranged on the output end of the first linear module 21, and the first linear module 21 and the second linear module 22 are both driven by a motor 23. The output end of the second linear module 22 is fixed with a support plate 221, and the connecting pipe 51 is arranged on the support pipe.

[0035] When the weight on the supporting table 4 needs to be moved, the first linear module 21 and the second linear module 22 cooperate to control the movement of the supporting plate 221, so as to move the suction ring 52 to be opposite to the weight. The external air pump works to provide suction force to the weight through the connecting pipe 51 and the suction ring 52, so as to realize the function of the suction ring 52 sucking the weight. At this time, under the flow equalization of the flow equalization disc 53 and the flow equalization hole 531, the uniformity of the suction force of the suction ring 52 is improved, so that the suction ring 52 can more stably suck the weight, and the possibility of deformation of the weight due to uneven suction force is reduced.

[0036] With reference to Figure 3 The connecting assembly 6 comprises a first connecting ring 61 and a supporting ring 62. The first connecting ring 61 is fixed on the connecting pipe 51, and the supporting ring 62 is arranged on the first connecting ring 61 along the circumferential direction of the first connecting ring 61. The suction ring 52 is provided with a first ring groove 521, the first connecting ring 61 is arranged in the first ring groove 521, and the inner wall of the first ring groove 521 is provided with a supporting groove 522, and the supporting ring 62 is arranged in the supporting groove 522.

[0037] The side of the suction ring 52 close to the connecting pipe 51 is fixed with a sealing ring 523, and the connecting pipe 51 is provided with a sealing groove 511, and the sealing ring 523 is arranged in the sealing groove 511.

[0038] When the suction ring 52 needs to be installed, the worker arranges the supporting ring 62 opposite to the first ring groove 521, and arranges the supporting ring 62 into the first ring groove 521. At this time, the suction ring 52 is slightly elastically deformed, and when the supporting ring 62 is opposite to the supporting groove 522, the supporting ring 62 can be arranged into the supporting groove 522, and the first connecting ring 61 is arranged into the first ring groove 521. At the same time, the sealing ring 523 is arranged into the sealing groove 511, and the connection between the suction ring 52 and the connecting pipe 51 is completed. And under the cooperation of the sealing ring 523 and the sealing groove 511, the sealing performance between the suction ring 52 and the connecting pipe 51 is improved, and the possibility of air leakage at the connection between the connecting pipe 51 and the suction ring 52 is reduced.

[0039] With reference to Figure 3 In order to improve the protection ability of the suction ring 52 to the weight, the side of the suction ring 52 away from the connecting pipe 51 is provided with a protective pad 7. The protective pad 7 is fixed with a second connecting ring 71, and the side of the suction ring 52 close to the protective pad 7 is provided with a second ring groove 524, and the second connecting ring 71 is arranged in the second ring groove 524.

[0040] The current equalizing disc 53 is fixed with a plurality of connecting blocks 532, and the protective pad 7 is provided with a plurality of connecting grooves 72, each connecting block 532 corresponds to one connecting groove 72, and the connecting block 532 is arranged in the corresponding connecting groove 72. The suction ring 52, the protective pad 7 and the current equalizing disc 53 are all made of rubber, and the hardness of the suction ring 52, the current equalizing disc 53 and the protective pad 7 gradually decreases, so that the protective pad 7 can more stably protect the weight.

[0041] The worker clamps the second connecting ring 71 into the second ring groove 524, so that the second connecting ring 71 abuts against the groove bottom of the second ring groove 524, and the installation of the protective pad 7 is completed, which on the one hand provides convenience for the connection between the protective pad 7 and the suction ring 52, and on the other hand improves the connection stability between the protective pad 7 and the suction ring 52. Then the worker makes the connecting block 532 opposite to the connecting groove 72 at the corresponding position, so that the connecting block 532 is clamped into the connecting groove 72 at the corresponding position, and the connection between the current equalizing disc 53 and the protective pad 7 is completed.

[0042] Referring to Figure 1 The supporting seat 41 is provided with a plurality of storage grooves 411 for placing the weights, and the supporting seat 41 is slidingly connected to the supporting table 4. The supporting table 4 is provided with a linear driving mechanism 42, and the output end of the linear driving mechanism 42 is connected to the supporting seat 41. The linear driving mechanism 42 can be a gas cylinder, an electric push rod, an electric cylinder, a telescopic motor 23 or other devices with linear reciprocating driving capability. In the embodiment, the linear driving mechanism 42 is a gas cylinder.

[0043] The supporting table 4 is provided with a blocking frame 43, and the side of the blocking frame 43 close to the supporting seat 41 is fixed with a sealing strip 431, and the sealing strip 431 abuts against the supporting seat 41.

[0044] When it is necessary to move the weights, the linear driving mechanism 42 controls the movement of the supporting seat 41 to move the supporting seat 41 to a set position. Due to the arrangement of the storage grooves 411, the weights in the same row are not easily affected by the suction force of the suction ring 52 at the same time, which reduces the possibility of multiple weights being sucked at the same time. At the same time, the blocking frame 43 and the sealing strip 431 isolate the adjacent two rows of weights, further reducing the possibility of multiple weights being sucked at the same time, thereby improving the stability of the weight transfer.

[0045] The implementation principle of the milligram weight calibration device with a protection function in the embodiment is that: in the process of transferring the weights, the external gas pump provides power, the connecting pipe 51 and the suction ring 52 cooperate and provide suction force for the weights to suck the weights. In the process of sucking the weights, the current equalizing disc 53 and the current equalizing hole 531 cooperate to improve the uniformity of the suction force provided by the suction ring 52, so that the suction ring 52 can more stably suck the weights, and the possibility of deformation of the weights in some positions due to uneven suction force is reduced.

[0046] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application, and thus: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
