Description

Technical Field

[0001] The utility model relates to the technical field of electronic scales, in particular to an electronic scale that automatically produces an intelligent pallet. Background Art

[0002] When assembling an electronic scale through an electronic scale production line, you first need to place the electronic scale base on the corresponding pallet, then move the base to different assembly areas by moving the pallet, install the corresponding mechanisms on the outer surface of the base one by one, and perform multiple tests on it until the electronic scale is assembled. The pallet used in this process can be called an electronic scale production pallet.

[0003] However, most existing production lines require manual labor to perform different operations on the production items at each workstation, such as downloading software at the first workstation, testing various interfaces, display screens and buttons at the second workstation, calibrating electronic scales at the third workstation, verifying electronic scales at the fourth workstation, and downloading shipping software and writing sequences at the fifth workstation. Manual production brings many problems that are difficult to control, such as missing problematic electronic scales, downloading the wrong software version, improper operation of weight machines during calibration and verification, etc., and this pallet cannot fix the electronic scale. During the later movement of the pallet, the electronic scale located on its upper end may move and fall to the ground. Therefore, it does not meet the existing needs. We have proposed an intelligent pallet for automated production of electronic scales. Utility Model Content

[0024] An indicator light 3 fixedly mounted on the outer surface of the smart pallet 1 is provided on one side of the QR code scanner 2, and a buzzer 4 also fixedly mounted on the outer surface of the smart pallet 1 is provided on one side of the indicator light 3;

[0025] The other side of the electronic scale 6 is provided with an NFC tag 5 attached to the upper end surface of the smart pallet 1, and one side of the NFC tag 5 is provided with a plurality of control buttons 20, and both sides of the lower end surface of the smart pallet 1 are fixedly mounted on a guide rail 8, and an automatic positioning fixing mechanism of the electronic scale installed inside the smart pallet 1 is provided below the electronic scale 6;

[0026] A barcode 7 is attached to the side surface of each electronic scale 6. This barcode 7 can provide relevant information of the electronic scale 6, such as the electronic scale model, internal unique identification code, etc. Each smart pallet 1 has an NFC tag 5. After the operator places the electronic scale 6 to be made on the smart pallet 1 and connects the control connector, the QR code scanner 2 on the smart pallet 1 starts to scan the barcode 7 on the electronic scale 6 to obtain relevant information. At this time, the NFC card reader also reads the ID of the pallet at the same time. The central control system binds the smart pallet 1 and the electronic scale 6, and installs the NFC card reader at a specific position on the assembly line. In this way, the position of the smart pallet 1 on the assembly line can be known in real time. Through real-time positioning, it can ensure that the central control can correctly perform the production task, so as to ensure that no errors occur in each production link, and record it throughout the process, so as to control the production status in real time. Through the above technical solution, the task can be completed more accurately, the product quality is improved, and the real-time analysis after the long-term production accumulation of big data can issue abnormal warnings in advance, so that people can intervene and deal with it as soon as possible, reducing the losses caused by abnormalities;

[0027] When a problem occurs during the test of the electronic scale 6 or its assembly process, the remote central control can light up the indicator light 3 indicating the test failure and use the buzzer 4 to prompt the production line personnel to remove the problematic electronic scale 6. In addition, the smart pallet 1 also provides multiple control buttons 20 for the production line personnel to operate. For example, when removing the abnormal electronic scale 6, it is necessary to press a control button 20 to remove the electronic scale 6 to notify the central control background that the electronic scale 6 has been removed from the smart pallet 1. The central control background communicates with the electronic scale 6 through the system of the smart pallet 1 in real time to complete related tasks that need to be performed, such as starting the electronic scale self-test program and then obtaining the self-test results, and performing calibration and verification in combination with the weight machine.

[0028] The automatic positioning and fixing mechanism of the electronic scale includes a stepper motor 9, the output shaft of the stepper motor 9 is connected to the transmission shaft 10 through a coupling, the upper side fixed sleeve of the outer surface of the transmission shaft 10 is provided with a bevel gear A11, and the four end corners of the outer surface of the bevel gear A11 are meshed with a bevel gear B12; after the electronic scale 6 is placed inside the electronic scale placement slot, the stepper motor 9 is started, and the transmission shaft 10 connected thereto and the bevel gear A11 fixedly sleeved on the outer surface of the transmission shaft 10 are driven by the stepper motor 9 to rotate, and when the bevel gear A11 rotates, the four bevel gears B12 meshed therewith will rotate synchronously.

[0029] A threaded rod 13 is connected to the axis of the bevel gear B12, and an internal threaded sleeve 14 matching its internal thread is sleeved on one side of the outer surface of the threaded rod 13, and a metal sleeve 15 is provided above the internal threaded sleeve 14, and the surface of the internal threaded sleeve 14 facing the metal sleeve 15 is fixed to the metal sleeve 15; when the bevel gear B12 rotates, the threaded rod 13 connected to the axis of the bevel gear B12 will rotate synchronously therewith, and since the internal threaded sleeve 14 sleeved on the outer surface of the threaded rod 13 is fixed to the metal sleeve 15, the internal threaded sleeve 14 itself cannot rotate. When the threaded rod 13 rotates, the internal threaded sleeve 14, which cannot rotate by itself, will move on the outer surface of the threaded rod 13 through the transmission of the threaded structure, and during the movement of the internal threaded sleeve 14, the metal sleeve 15 fixed thereto will also move accordingly.

[0030] A positioning rod 16 is slidably connected to one side of the metal sleeve 15, and the outer surface of the positioning rod 16 fits with the inner wall of the metal sleeve 15; a connecting rod 17 is fixedly provided on one side of the inner wall of the metal sleeve 15, and the top end of the connecting rod 17 is inserted into the interior of the positioning rod 16, and a metal ring 18 is fixedly provided on the outer surface of the connecting rod 17 located inside the positioning rod 16, and a spring 19 is connected to the surface of the metal ring 18 facing the electronic scale 6; when the metal sleeve 15 moves in the direction toward the electronic scale 6, the positioning rod 16 located inside and connected thereto will also move accordingly until the positioning rod 16 contacts the electronic scale 6, and when the positioning rods 16 located at the front and rear of the electronic scale 6 contact the When the positioning rods 16 located on the left and right sides of the electronic scale 6 have not yet touched the electronic scale 6, do not turn off the stepper motor 9, and continue to push the positioning rods 16 inward. At this time, the positioning rods 16 that have already touched the electronic scale 6 will stay in place, and as the metal sleeve 15 moves, it will squeeze the spring 19 located inside the positioning rods 16. When the positioning rods 16 located on the left and right sides of the electronic scale 6 also touch the electronic scale 6, turn off the stepper motor 9. Through the four positioning rods 16 that move inward synchronously, electronic scales 6 of various sizes can be automatically positioned and fixed. The above technical solution can prevent the electronic scale 6 from falling.

[0031] A circular cover plate is provided below the stepper motor 9 and is located on the lower end surface of the smart pallet 1 , and the smart pallet 1 and the circular cover plate are fixed by screws.
