[0028] Please refer to Figure 1 The embodiment of the present application provides a weighing mechanism 100. The weighing mechanism 100 is used for weighing a product 200 to determine whether the weight of the product 200 meets the production requirements. Wherein, the product 200 can be a battery plate.

[0029] Please refer to Figure 2 and Figure 3The weighing mechanism 100 comprises a base 10, a platform 20, a plurality of elastic assemblies 30 and a sensor 40. The platform 20, the plurality of elastic assemblies 30, the sensor 40 and the like are arranged on the base 10, so that the weighing mechanism 100 is modularly arranged.

[0030] The platform 20 is arranged opposite to the base 10 and above the base 10. The platform 20 is a plate-like object, and the platform 20 is provided with a position-avoiding hole 21. The platform 20 is used for carrying a product 200, and when the platform 20 carries the product 200, the position-avoiding hole 21 is covered by the product 200. In the embodiment, the position-avoiding hole 21 can be a rectangular hole. It can be understood that in other embodiments, the position-avoiding hole 21 can also be a circular hole, an elliptical hole or a hole with other shapes, and the embodiment of the present application does not make specific limitation thereon.

[0031] The plurality of elastic assemblies 30 are evenly arranged around the position-avoiding hole 21, and the plurality of elastic assemblies 30 are connected between the platform 20 and the base 10. The platform 20 can be elastically moved up and down relative to the base 10 through the elastic assemblies 30. In the embodiment, the number of the elastic assemblies 30 can be four, and the four elastic assemblies 30 are arranged at four corners of the platform 20. It can be understood that in other embodiments, the number of the elastic assemblies 30 can also be more or less, and the number can be set according to actual conditions.

[0032] The sensor 40 is arranged on the base 10 and opposite to the position-avoiding hole 21, and the sensor 40 is used for sensing the product 200. In the embodiment, the sensor 40 is arranged at the center of the base 10 and opposite to the center of the position-avoiding hole 21. The sensor 40 can be a distance sensor, and the sensor 40 senses the distance between the sensor 40 and the product 200 to determine whether the mass of the product 200 meets the production requirements. It can be understood that in other embodiments, the sensor 40 can also be a functional object with a sensing function, and the embodiment of the present application does not make specific limitation thereon.

[0033] In use, the weighing mechanism 100 of the embodiment places the product 200 to be weighed on the loading platform 20 so that the product 200 covers the avoidance hole 21 on the loading platform 20 and the product 200 is opposite to the inductor 40; after the product 200 is placed on the loading platform 20, the loading platform 20 is moved downward under the gravity of the product 200 and the elastic assembly 30 is compressed; if the weight of the product 200 meets the production requirement, i.e. the weight of the product 200 is within the preset weight range and the weight of the product 200 is not enough to overcome the elastic force of the elastic assembly 30 to press the loading platform 20 downward very deeply, the inductor 40 cannot sense the product 200, in which case it can be determined that the weight of the product 200 meets the production requirement; if the weight of the product 200 does not meet the production requirement, i.e. the weight of the product 200 is beyond the preset weight range and the weight of the product 200 is enough to overcome the elastic force of the elastic assembly 30 to press the loading platform 20 downward very deeply, the distance of the downward movement of the loading platform 20 will increase, so that the inductor 40 senses the product 200, in which case it can be determined that the weight of the product 200 is beyond the preset weight range, thereby realizing the detection of the weight of the product 200.

[0034] It can be understood that according to the actual production situation, the weight of the product 200 beyond the preset weight range can be determined as meeting the production requirement and the weight of the product 200 within the preset weight range can be determined as not meeting the production requirement, which can be set according to the actual situation, and the embodiment of the application does not make a specific limitation.

[0035] In order to improve the application range of the weighing mechanism 100, in the embodiment, the weighing mechanism 100 further comprises a plurality of counterweight assemblies 50, the plurality of counterweight assemblies 50 are evenly arranged around the avoidance hole 21, the plurality of counterweight assemblies 50 are connected to the side of the loading platform 20 facing the base 10, the plurality of counterweight assemblies 50 are correspondingly arranged and adjacent to the plurality of elastic assemblies 30, and each counterweight assembly 50 is arranged on the side of the corresponding elastic assembly 30 facing the avoidance hole 21. In the embodiment, the number of the counterweight assemblies 50 is four. In this way, by arranging the above-mentioned counterweight assemblies 50, the weight of the loading platform 20 can be increased or decreased by increasing or decreasing the weight of the counterweight assemblies 50, so that the products 200 of different weights can be sensed or not sensed by the inductor 40 by cooperating with the counterweight assemblies 50 to overcome the elastic force of the elastic assemblies 30, the weighing mechanism 100 can weigh the products 200 of different weights, thereby improving the application range of the weighing mechanism 100. At the same time, by arranging the counterweight assemblies 50 on the loading platform 20, the balance of the loading platform 20 is ensured and the stability of the upward and downward movement of the loading platform 20 is ensured.

[0036] It can be understood that in other embodiments, the number of groups of the counterweight assemblies 50 can be more or less, which can be set according to the actual situation, and the embodiment of the application does not make a specific limitation.

[0037] In the embodiment, each counterweight assembly 50 comprises a connecting piece 51, a blocking piece 52 and at least one counterweight 53.

The number of counterweights 53 can be set according to actual needs. In this way, by setting the specific structure of the counterweight assembly 50, the weight of the counterweight assembly 50 can be increased or decreased by increasing or decreasing the counterweights 53. In addition, the installation method of the counterweight assembly 50 is simple, which is conducive to quickly increasing or decreasing the counterweights 53.

[0038] In order to avoid the counterweight assembly 50, in the embodiment, a plurality of avoidance holes 121 are formed on the base 10, and the plurality of avoidance holes 121 correspond one-to-one to the plurality of counterweight assemblies 50. Each avoidance hole 121 is adapted to accommodate the corresponding counterweight assembly 50, so that the base 10 avoids the counterweight assembly 50. In this way, by providing avoidance holes 121 on the base 10, when the platform 20 moves the counterweight assembly 50 close to the base 10 under the action of the gravity of the product 200, the base 10 avoids the counterweight assembly 50 through the avoidance holes 121, thereby ensuring the smooth downward movement of the platform 20.

The support piece 12 is arranged on the support 11, the platform 20 is arranged on the side of the support piece 12 away from the support 11, the assembly piece 13 is arranged on the support piece 12 and faces the avoidance hole 21, the plurality of elastic assemblies 30 are connected between the platform 20 and the support piece 12, and the inductor 40 is arranged on the assembly piece 13. In this way, by setting the specific structure of the above-mentioned base 10, the installation of the platform 20, the elastic assembly 30 and the inductor is realized; at the same time, the height of the platform 20, the elastic assembly 30 and the inductor is raised. The avoidance hole 121 is formed on the support piece 12.

[0040] In the embodiment, the base 10 further comprises four adjusting legs 14. The four adjusting legs 14 are respectively threadedly connected to the end of the support 11 away from the support piece 12. In this way, by setting the above-mentioned adjusting legs 14, on the one hand, the balance of the support 11 is ensured through the adjusting legs 14, and on the other hand, the height of the support 11 can be correspondingly raised or lowered through the adjusting legs 14, so as to adjust the height of the platform 20 and improve the applicability of the weighing mechanism 100.

[0041] In order to improve the degree of automation of the weighing mechanism 100, in the embodiment, the base 10 further comprises a controller 15 and a plurality of buttons 16. The controller 15 is arranged in the support 12, and the controller 15 can be a central processing unit or other functional objects capable of receiving, processing, transmitting and storing signals. The plurality of buttons 16 are arranged at intervals on the side of the support 12, and the controller 15 is electrically connected with the inductor 40 and the plurality of buttons 16 respectively. The controller 15 can receive the signal of the inductor 40, and the controller 15 can also receive the instruction of the button 16. Among them, the functions of the plurality of buttons 16 are different, and the functions of the plurality of buttons 16 include but are not limited to emergency stop switch, start switch, stop switch and the like. In this way, by arranging the above-mentioned controller 15 and button 16, the degree of automation of the weighing mechanism 100 is improved.

[0042] For example, the controller 15 receives the value detected by the inductor 40, and the controller 15 determines whether the weight of the product 200 meets the preset requirement according to the value. The controller 15 can also send the determination result to a display for display, or to a voice player for voice playing.

[0043] In the embodiment, the side of the support 12 facing the platform 20 is provided with four protrusions 122, and the four protrusions 122 correspond to the four elastic components 30 one by one.

Specifically, the other end of the guide piece 31 slides through the guide hole 123, and the elastic piece 32 abuts between the protrusion 122 and the platform 20. In this way, by arranging the specific structure of the above-mentioned elastic component 30, the platform 20 is elastically moved up and down relative to the support 12 by the elastic piece 32, and the stability of the platform 20 during movement is ensured by the guide piece 31.
