Please refer to Figure 1. An embodiment of the present disclosure provides a weighing equipment, including a transfer device and a weighing device 200. The transfer device is used to transfer the workpiece b to the weighing station a1, and the weighing device 200 is used in the weighing station a1. Weighing station a1 weighs workpiece b. Optionally, the weighing device 200 may use an electronic scale.

In some optional embodiments, the workpiece b may be a holder, and the holder is loaded with a battery. In other embodiments, the workpiece b can also be other products, which is not limited here.

The transfer device includes a transfer turntable 10 and a positioning component 20 . The transfer turntable 10 is controllably rotatable around its own axis, and has a positioning groove 11 for accommodating the workpiece b. When the transfer turntable 10 rotates around its own axis, it can drive the workpiece b accommodated in the positioning slot 11 to the weighing station a1, so that the weighing device 200 weighs the workpiece b. The positioning slot 11 has an opening 110 for the workpiece b to enter or exit, that is to say, the workpiece b can enter or exit the positioning slot 11 through the opening 110 . The positioning assembly 20 includes a stop 21 movably connected to the transfer turntable 10 . The stopper 21 can enter or exit the opening 110 of the positioning groove 11 during its movement relative to the transfer turntable 10 . When the workpiece b is accommodated in the positioning slot 11, the stopper 21 enters the opening 110 of the positioning slot 11 and abuts the workpiece b accommodated in the positioning slot 11; when the workpiece b enters and exits the positioning slot 11 through the opening 110, the stopper 21 The block 21 exits the opening 110 of the positioning groove 11 under the pressure of the workpiece b, so as to allow the workpiece b to enter and exit the positioning groove 11 through the opening 110 .

When the above-mentioned transfer device is actually used, the workpiece b to be weighed is placed in the positioning groove 11 through the opening 110, and the stopper 21 that enters the opening 110 is used to abut the workpiece b, so that the workpiece b is It is limited in the positioning groove 11 to prevent the workpiece b from escaping from the positioning groove 11 . Then, the transfer turntable 10 rotates around its own axis until the workpiece b is brought to the weighing station a1. Then, the weighing device 200 weighs the workpiece b arriving at the loading station.

Compared with the prior art method of using magnets to adsorb and fix the workpiece b, in this disclosure, the stopper 21 that enters the opening 110 of the positioning groove 11 is used to limit the workpiece b in the positioning groove 11, thus avoiding the possibility of damage caused by the magnet. The magnetic field causes interference to the weighing device 200, thus ensuring the accuracy of the weighing data.

In some specific embodiments, the transfer device further includes a first driving component 60 (see FIG. 3 ), which is drivingly connected to the transfer turntable 10 to drive the transfer turntable 10 to rotate around its own axis. It should be noted that the first driving component 60 can adopt relatively mature existing technology, as long as it can drive the transfer turntable 10 to rotate around its own axis, and is not limited here.

In an optional embodiment of the present disclosure, the number of positioning grooves 11 is multiple, and the plurality of positioning grooves 11 are arranged at intervals along the circumferential direction of the transfer turntable 10 . There are multiple positioning components 20 , and each positioning component 20 is disposed between two adjacent positioning grooves 11 to position the workpiece b in the two adjacent positioning grooves 11 . Each positioning component 20 includes an elastic member 22 and two stops 21 . The two stoppers 21 correspond to the two adjacent positioning grooves 11 one-to-one. The elastic member 22 abuts on the two stoppers 21 in order to exert a pre-tightening force on the two stoppers 21 , so that the two stoppers 21 have a tendency to move into the openings 110 of the corresponding positioning grooves 11 respectively.

In this way, when the workpiece b enters the positioning groove 11 from the opening 110 under the action of external force, the workpiece b squeezes the stopper 21 that enters the opening 110, so that the stopper 21 overcomes the pre-tightening force provided by the elastic member 22. After exiting the opening 110 (at this time, the compression amount of the elastic member 22 increases), the workpiece b smoothly enters the positioning groove 11 from the opening 110 . After the workpiece b enters the positioning groove 11, the stopper 21 enters the opening 110 of the positioning groove 11 again under the action of the pre-tightening force provided by the elastic member 22, and abuts with the workpiece b in the positioning groove 11. Thus, the workpiece b is limited in the positioning groove 11 . Alternatively, the elastic member 22 may be a spring.

It should be noted that, in order to limit the workpiece b in each positioning slot 11, each positioning slot 11 is provided with at least one stopper 21, that is, the workpiece b in each positioning slot 11 has a corresponding stopper. Block 21 defines it. Specifically, in one embodiment, each positioning slot 11 is arranged in groups of two, the two positioning slots 11 in each group are adjacent to each other, and the above-mentioned positioning assembly is disposed between the two positioning slots 11 in each group. 20, so that the two stops 21 of each positioning assembly 20 respectively limit the workpiece b in the two positioning slots 11 in the same group.

In other embodiments, a positioning assembly 20 may also be provided between every two adjacent positioning grooves 11 , so that the workpiece B in each positioning groove 11 can be limited by two stops 21 .

Please refer to FIG. 2 . In this embodiment, each stopper 21 includes a block body 210 and a protrusion 212 connected to the block body 210 . The two block bodies 210 of the positioning assembly 20 are both movably connected to the transfer turntable 10 , and the elastic member 22 is in contact between the two block bodies 210 . During the movement of the block body 210 relative to the transfer turntable 10 , the protrusion 212 can be driven into or out of the opening 110 corresponding to the positioning groove 11 . In this way, when the workpiece b enters the positioning groove 11 from the opening 110 under the action of external force, the protrusion 212 overcomes the pre-tightening force provided by the elastic member 22 under the extrusion of the workpiece b and exits the opening 110, so that the workpiece b can smoothly move out of the opening 110. into the positioning groove 11. After the workpiece b enters the positioning groove 11, under the action of the pre-tightening force provided by the elastic member 22, the protrusion 212 enters the opening 110 of the positioning groove 11 again and contacts the workpiece b in the positioning groove 11, thereby The workpiece b is limited in the positioning groove 11 .

Specifically in the embodiment, the protruding portion 212 has a first inclined surface 2121 and a second inclined surface 2123 for contacting the workpiece b entering and exiting the positioning groove 11 . The first inclined surface 2121 is located on the protruding portion 212 Facing the side inside the positioning groove 11 , the second inclined surface 2123 is located on the side of the protrusion 212 away from the positioning groove 11 . The protruding portion 212 has a connection end close to the block body 210 and a free end away from the block body 210 . In the direction from the connecting end to the free end, the distance between the first inclined surface 2121 and the second inclined surface 2123 gradually decreases. In this way, when the workpiece b enters the positioning groove 11 from the opening 110 under the action of external force, first, the workpiece b contacts the second inclined surface 2123, and the protruding portion 212 is squeezed by the workpiece b and gradually exits the opening 110, so that the workpiece b moves along the second inclined surface 2123 and gradually enters the positioning groove 11 . After the workpiece b slides through the second inclined surface 2123, it contacts the first inclined surface 2121, and continues to move toward the positioning groove 11, so that the protruding portion 212 gradually enters the opening 110 under the action of the preload force provided by the elastic member 22. , until the workpiece b completely enters the positioning groove 11. At this time, the first inclined surface 2121 of the protrusion 212 remains in contact with the workpiece b, thereby limiting the workpiece b in the positioning groove 11 .

It should be noted that when the workpiece b moves in and out of the positioning slot 11 from the opening 110 under the action of external force, the first inclined surface 2121 and the second inclined surface 2123 are used to contact the workpiece b respectively. Since the first inclined surface 2121 and the second inclined surface 2123 The distance between the two inclined surfaces 2123 gradually decreases in the direction from the connecting end to the free end, so that the protrusion 212 can smoothly enter or Exit the opening 110 of the positioning groove 11 to ensure that the workpiece b can smoothly enter and leave the positioning groove 11 through the opening 110 by squeezing the protrusion 212 .

Preferably, the first inclined surface 2121 and the second inclined surface 2123 transition smoothly at the free end of the protruding portion 212, thereby further ensuring that the workpiece b can smoothly enter and exit the opening 110 by squeezing the protruding portion 212 under the action of external force. slot 11.

Specifically in this embodiment, the transfer turntable 10 has a plurality of assembly cavities 12 for receiving the positioning components 20 . A communication port 13 is provided between each assembly cavity 12 and two adjacent positioning grooves 11 . The protruding portion 212 of each stopper 21 enters or exits the opening 110 of the positioning groove 11 through the corresponding communication port 13 . In this way, the two stoppers 21 and the elastic member 22 of the positioning assembly 20 are assembled in the corresponding assembly cavity 12, and communication ports 13 are opened between the assembly cavity 12 and the two adjacent positioning grooves 11, so that the stoppers The protruding portion 212 of 21 enters or exits the opening 110 of the corresponding positioning groove 11 through the communication port 13, thereby positioning the workpiece b in the positioning groove 11.

Further, the stopper 21 also includes a limiting portion 214 connected to the block body 210 . The assembly cavity 12 includes a cavity body 121 and two sub-cavities 123 connected with the cavity body 121 . The cavity body 121 and The above-mentioned communication opening 13 is provided between two adjacent positioning grooves 11 . The block bodies 210 of the two stoppers 21 of the positioning assembly 20 are located in the cavity body 121 , and the limiting portions 214 of the two stoppers 21 are located in the two sub-cavities 123 respectively. There is a gap between each limiting part 214 and the side wall of the sub-cavity 123 in the circumferential direction of the transfer turntable 10, so that each limit part 214 has a certain movable space in the sub-cavity 123 along the circumferential direction of the transfer turntable 10. Therefore, the protrusion 212 on the block body 210 can be driven to enter or exit the opening 110 of the positioning groove 11 . In this way, the sub-cavity 123 is used to accommodate the limiting portion 214 of the stopper 21, so that the limiting portion 214 can move in the sub-cavity 123 along the circumferential direction of the transfer turntable 10, thereby driving the protruding portion 212 of the stopper 21 to enter or exit the corresponding position. At the opening 110 of the positioning groove 11, the workpiece b is limited in the corresponding positioning groove 11.

Further, the surface of the end of the limiting portion 214 away from the block body 210 is a first arc surface 2141, and the wall surface of the end of the sub-cavity 123 away from the cavity body 121 is a second arc surface 1231. The first arcuate surface 2141 and the second arcuate surface 1231 are slidingly matched, thereby making the movement of the limiting portion 214 in the sub-cavity 123 smoother and more flexible, thereby driving the protruding portion 212 to enter or exit the opening 110 of the positioning groove 11 Movement is smoother and more flexible.
