Description

Technical Field

[0001] This utility model relates to the field of weight detection technology, and in particular to a multifunctional weight detection device. Background Technology

[0002] Weight detection equipment converts gravity into an electrical signal through sensors, which is then processed and displayed as a weight value. Its core component is a load cell (such as a strain gauge sensor). When an object is placed on the load cell, the sensor deforms, causing a change in resistance. A bridge circuit converts this change into a voltage signal, which is then calculated and displayed by a processor. Existing weight detection equipment has relatively limited functionality, only capable of measuring the weight of objects, thus presenting certain limitations. Therefore, a multifunctional weight detection device needs to be designed to address this issue. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a multifunctional weight detection device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A multifunctional weight detection device includes a base with a detection groove on the top and a detection frame fixedly mounted on the top of the base. A pressure sensor is installed in the detection groove, and a support base is connected to the top of the pressure sensor. A positioning component is installed on the top of the support base. The detection frame includes a main fixing plate and a secondary fixing plate. Several infrared sensors are installed in the main fixing plate, and a lifting component is installed in each infrared sensor. The lifting component is connected to a top plate, and a laser sensor head is fixedly mounted in the top plate. A display screen and a control switch are connected to one side of the top plate.

[0006] Preferably, the positioning component includes a compression spring, and a positioning post is connected and installed on the top of the compression spring. There are several positioning posts, which are distributed in a circular array to assist in positioning the item and prevent it from shifting. The top of the positioning post adopts an arc-shaped structure design to avoid damage to the surface of the item when in contact, thus playing a protective role.

[0007] Preferably, a connecting rod is fixedly installed at the bottom of the positioning column, and a lifting groove adapted to the connecting rod is opened in the support base. A compression spring is provided between the lifting groove and the positioning column. A trigger sensor is provided in the lifting groove, and the bottom of the connecting rod can be connected to the trigger sensor. The area, length, width and other data of the bottom of the item can be determined by the number and position of the connecting rods in contact with the trigger sensor.

[0008] Preferably, there are two auxiliary fixing plates, which are located on both sides of the main fixing plate. The auxiliary fixing plates are designed with an inclination, which not only facilitates the placement of items, but also provides some light blocking, making the detection of the infrared sensor and the laser sensor head more accurate. The bottom of the main fixing plate is flush with the detection groove.

[0009] Preferably, the lifting assembly includes a drive motor and a lead screw, and the lead screw is connected to the top plate by a thread, thereby controlling the lifting of the top plate.

[0010] Preferably, the laser sensor head adopts a built-in design, and a transparent partition is provided at the bottom of the laser sensor head to prevent the laser sensor head from contacting the object and causing damage when it descends, thus playing a protective role.

[0011] The beneficial effects of this utility model are:

[0012] This invention, in addition to detecting the weight of an item through a pressure sensor, can also position the item through a positioning component. It can also be used with a trigger sensor to determine the area, length, and width of the item's bottom. It is equipped with a laser sensor head to confirm the area, length, and width of the top from the top. At the same time, the height of the item can be confirmed by controlling the lifting of the top plate through a lifting component, and the width of the item at different heights can be detected by an infrared sensor. It can detect multiple data at the same time and has strong functionality. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example: Refer to Figure 1-4 A multifunctional weight detection device includes a base 1 with a detection groove on its top and a detection frame 2 fixedly mounted on the top of the base 1. A pressure sensor 3 is installed within the detection groove, and a support base 4 is connected to the top of the pressure sensor 3. A positioning component 5 is installed on the top of the support base 4. The positioning component 5 includes a compression spring, and a positioning post is connected to the top of the compression spring. Several positioning posts are arranged in a circular array to assist in positioning the object and prevent displacement. The top of each positioning post has an arc-shaped design to avoid damage to the surface of the object upon contact, providing protection. A connecting rod is fixedly mounted at the bottom of each positioning post, and a lifting groove adapted to the connecting rod is provided within the support base 4. A compression spring is installed between the lifting groove and the positioning post. A trigger sensor is installed within the lifting groove, and the bottom of the connecting rod can connect to the trigger sensor. The area, length, and width of the object's bottom can be determined by the number and position of the connecting rods in contact with the trigger sensor. The detection frame 2 includes a main fixing plate 6 and a secondary fixing plate 7. The main fixing plate 6 houses several infrared sensors 8, each containing a lifting assembly 9 connected to a top plate 10. The lifting assembly 9 includes a drive motor and a lead screw, which is threaded to the top plate 10 to control its lifting. A laser sensor head 11 is fixedly installed within the top plate 10. There are two secondary fixing plates 7, located on either side of the main fixing plate 6. The secondary fixing plates 7 are angled, facilitating the placement of items and providing some light blocking, thus improving the accuracy of the infrared sensors 8 and the laser sensor head 11. The bottom of the main fixing plate 6 is flush with the detection slot. The laser sensor head 11 is internally mounted, with a transparent partition at its bottom to prevent damage from contact with items during descent. A display screen 12 and a control switch 13 are connected to one side of the top plate 10.

[0020] Working principle: When in use, the item needs to be placed on the positioning component 5. The positioning component 5 retracts under force, and the connecting rod contacts the trigger sensor to detect the area and length and width of the bottom of the item. At the same time, the pressure sensor 3 detects the weight of the item when it is placed. Then, the lifting component 9 is opened to control the top plate 10 to descend and connect with the top of the item to determine the height of the item. The laser sensor head 11 detects the area and length and width of the top of the item. Then, the infrared sensor 8 detects the width of the item at different heights and transmits the data to the display screen 12 for display.
