Description

Technical Field

[0001] This utility model relates to the field of weighing equipment technology, and in particular to a weighing sensor with detection function. Background Technology

[0002] A load cell is a widely used measuring device, and its main structure includes a housing, a pressure resistor, and related conversion circuits.

[0003] In existing technologies, to ensure the normal use of load cells, after a period of time, it is necessary for inspectors to test the performance of the load cells. During the test, inspectors need to place fixed weights on the force-bearing surface of the load cell's force-measuring mechanism, and then compare the data displayed on the display device. If the data displayed on the display device matches the weight of the weights, it means that the load cell is in good working order. If the weight is too heavy or too light, it means that the load cell is not performing well. This requires manual handling of the weights, which is time-consuming and labor-intensive, thus reducing the efficiency of the test. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a weighing sensor with detection function. It is convenient to detect, avoids the trouble of manually picking up and putting down weights, saves time and effort, and thus improves the detection efficiency. It can effectively solve the problems in the background technology.

[0007] Furthermore, the lifting mechanism includes an electric push rod and a lifting seat. The electric push rod is installed on the top of the base, and the lifting seat is fixed to the telescopic end of the electric push rod. The weight is placed on the lifting seat, and the electric push rod is electrically connected to a PLC controller.

[0008] Furthermore, the clamping mechanism includes a guide rod and a clamping plate, the end of the guide rod being fixedly connected to a bracket on the bearing plate, and the clamping plate being slidably connected to the guide rod.

[0009] Furthermore, the clamping mechanism also includes a servo motor and a bidirectional lead screw.

[0010] Furthermore, the connecting mechanism includes a plug and a socket, with the plug fixed to the side of the clamp and the socket fixed to the top of the weight, and the plug and socket being inserted into each other.

[0011] Furthermore, the clamp and the plug are arranged in an "L" shape.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This weighing sensor with detection function has the following advantages: the weight is raised and lowered by the lifting mechanism, and the connecting mechanism is connected or separated from the weight by the clamping mechanism. Then, the lifting mechanism returns to its original position, at which point the weight is suspended at the bottom of the support plate.

Detailed Implementation

[0018] The present invention will be explained in detail through the following embodiments. The purpose of disclosing the present invention is to protect all technical improvements within the scope of the present invention.

[0019] Please see Figure 1-4This embodiment provides a technical solution: a weighing sensor with detection function, including a base 1, lifting mechanisms 3 installed on the top left and right sides of the base 1, weights 6 placed on the lifting parts of the lifting mechanisms 3, a weighing sensor body 8 installed in the middle of the base 1, a bearing plate 7 fixed on the top of the weighing sensor body 8, a clamping mechanism 4 installed at the bottom of the bearing plate 7, the clamping part of the clamping mechanism 4 being detachably connected to the weights 6 through a connecting mechanism 5, and a PLC controller 2 installed on the side of the base 1, the PLC controller 2 being electrically connected to an external power supply.

[0020] The lifting mechanism 3 includes an electric push rod 31 and a lifting seat 32. The electric push rod 31 is installed on the top of the base 1, and the lifting seat 32 is fixed to the telescopic end of the electric push rod 31. The weight 6 is placed on the lifting seat 32. The electric push rod 31 is electrically connected to the PLC controller 2. When the weighing sensor body 8 is not weighing, the telescopic end of the electric push rod 31 drives the lifting seat 32 to move up and down. The lifting seat 32 moves the weight 6 up and down, so that the weight 6 can be moved to a position that is easy for the clamping mechanism 4 to clamp.

[0021] The clamping mechanism 4 includes a guide rod 42 and a clamping plate 43. The end of the guide rod 42 is fixedly connected to the bracket on the bearing plate 7, and the clamping plate 43 is slidably connected to the guide rod 42. The clamping mechanism 4 also includes a servo motor 41 and a bidirectional lead screw 44. The bidirectional lead screw 44 is rotatably mounted on the inner side of the bracket of the bearing plate 7 and is threadedly connected to the clamping plate 43. The servo motor 41 is mounted on the side of the bracket of the bearing plate 7, and the output shaft of the servo motor 41 is fixedly connected to one end of the bidirectional lead screw 44. The servo motor 41 is electrically connected to the PLC controller 2. The output shaft of the servo motor 41 drives the bidirectional lead screw 44 to rotate. The bidirectional lead screw 44 is threadedly driven to the clamping plate 43, and the clamping plate 43 moves linearly along the guide rod 42. It is easy to operate and facilitates the connection or separation of the connecting mechanism 5 and the weight 6.

[0022] The connecting mechanism 5 includes a plug 51 and a socket 52. The plug 51 is fixed to the side of the clamping plate 43, and the socket 52 is fixed to the top of the weight 6. The plug 51 and the socket 52 are inserted into each other. The clamping plate 43 and the plug 51 are arranged in an "L" shape. The clamping plate 43 moves linearly along the guide rod 42 until the plug 51 on the clamping plate 43 is inserted into the inside of the socket 52. Then, the lifting mechanism 3 returns to its original position. At this time, the weight 6 is suspended at the bottom of the bearing plate 7. Then, the detection work of the weighing sensor body 8 can be completed according to the detection method in the prior art. The detection is convenient and avoids the trouble of manually picking up and putting down the weight 6, saving time and effort, thereby improving the detection efficiency.

[0023] The working principle of the weighing sensor with detection function provided by this utility model is as follows: When the weighing sensor body 8 is not weighing, the telescopic end of the electric push rod 31 drives the lifting seat 32 to move up and down. The lifting seat 32 lifts and lowers the weight 6, thereby moving the socket 52 on the weight 6 to the position corresponding to the plug 51. Then, the output shaft of the servo motor 41 drives the bidirectional lead screw 44 to rotate. The bidirectional lead screw 44 is threadedly driven with the clamping plate 43. The clamping plate 43 moves linearly along the guide rod 42 until the plug 51 on the clamping plate 43 is inserted into the inside of the socket 52. Then, the lifting mechanism 3 returns to its original position. At this time, the weight 6 is suspended at the bottom of the support plate 7. Then, the detection work of the weighing sensor body 8 can be completed by following the detection method in the prior art.
