Description

Technical Field:

[0001] The present invention relates to the technical field of coal mine safety, and in particular to an automatic aging line for mine-used power supplies, an aging system for the aging line, and an aging method. Background Art:

[0002] Since non-explosion-proof mine-used products need to be flameproof treated, their volume and weight are relatively large, and general aging cabinets cannot accommodate and carry multiple mine-used power supplies. Therefore, currently, relevant manufacturers basically adopt the ground flat aging method or the linear workbench aging method. The utilization rate of the product aging space is extremely low, and the input AC supply voltage cannot fluctuate within a certain range. Only fixed-value resistors can be used for constant-load loading aging at the DC output end of the mine-used power supply, and the load cannot change. Various parameters and protection functions during the aging process cannot be read in real time, and only the functions are verified through the overall inspection after the aging is completed. From the aspect of verifying the electrical performance, the current aging method is an incomplete aging method, with certain quality risks and unable to verify the working performance of the mine-used power supply under extreme environments.

[0003] The aging systems of mine-used power supply products in the prior art have the following disadvantages:

[0004] (1) During the aging process of the mine-used power supply, only the rated working voltage can be provided at the AC input end, and the input voltage of the mine-used power supply is not adjustable;

[0005] (2) Only fixed-value resistors can be used for constant-load aging at the DC output end of the mine-used power supply, and the load is not adjustable;

[0006] (3) Various parameter indicators of the currently aging mine-used power supply cannot be read in real time;

[0007] (4) It does not have the ability to monitor the aging equipment in real time. In case of an abnormal situation, protective measures cannot be implemented, and accidents cannot be avoided;

[0027] The present invention also provides a mine power supply automatic aging system, which includes several of the above-mentioned mine power supply automatic aging lines and a server connected to them through Ethernet. The mine power supply automatic aging line is controlled by an aging line control system. The aging line control system includes an integrated control machine and an automatic loading and unloading control device connected to the integrated control machine, and several power supply automatic aging rack control systems. The power supply automatic aging rack control system includes an aging power supply, an aging monitoring unit, a data acquisition board, an AC-DC process control power supply, an infrared temperature sensor, an environment sensor, a smoke sensor, an alarm lamp, a conversion board, and an automatic loading and unloading module. The conversion board is connected to the integrated control machine, and the aging monitoring unit, the data acquisition board, the AC-DC process control power supply, the infrared temperature sensor, and the environment sensor are respectively connected to the conversion board. The aging power supply is connected to the aging monitoring unit, the smoke sensor and the alarm lamp are connected to the data acquisition board, and the automatic loading and unloading module is connected to the automatic loading and unloading control device.

The data acquisition control board is connected to the DC process control power supply and the aging power supply through a contactor. The protocol conversion board is connected to the aging power supply through a CAN conversion board. The electronic load module is connected to the aging power supply.

[0029] The present invention also provides a mine power supply automatic aging method, which uses the above-mentioned mine power supply automatic aging line and includes the following steps:

[0030] (1) The piggyback AGV conveying mechanism transports the mine power supply from the production line to the aging line. First, the rail-mounted RGV conveying mechanism transports the mine power supply carrying tray carrying the mine power supply to the corresponding aging unit according to the pre-set placement order. The mine power supply carrying tray is accurately docked with the aging unit to achieve electrical connection.

[0031] (2) Transport the mine power supplies to be aged entering the aging line to the corresponding aging units one by one according to the above method.

[0032] (3) After the placement of the mine power supplies is completed, the system starts the pre-configured aging process, starts to provide alternating current to each mine power supply one by one, and tests its relevant parameters. If any abnormal situation is found during the test, the aging of the corresponding mine power supply will be stopped at any time. The system cuts off the power supply and gives the specific location of the faulty mine power supply and alarms.

[0033] (4) After there is no abnormal phenomenon in the power-on test, the system will run the regular aging process. The input AC voltage fluctuates regularly. The electronic load module is used to detect the DC output voltage value in real time, and different load sizes are given regularly at the same time. The output voltage value of the mine power supply is detected, and at the same time, the overcurrent protection and short-circuit protection functions of the DC output of the mine power supply are tested.

[0034] (5) During the aging cycle of the mine power supply, the system monitors all aging parameters of the mine power supply in real time during the aging process. In case of any abnormal situation, an alarm signal is given in real time and accident avoidance measures are initiated.

[0035] (6) After aging is completed, the system controls the rail-mounted RGV consignment mechanism to sequentially consign the mine power supply from the aging unit to the aging exit of the aging line according to the received instructions. Then, the piggyback AGV conveying mechanism transports the mine power supply to the factory inspection unit for factory inspection, completing the entire aging process.

[0036] Among them, after the mine power supply enters the aging line, the system will perform a two-dimensional code scanning operation on it, read its relevant information, bind its information to the aging unit, and store the data read during the aging process into the whole machine information corresponding to this station.

[0037] In the present invention, the mine power supply adopts a high-density three-dimensional shelf storage method, which greatly reduces the floor area occupied during the aging of the mine power supply. The load of the mine power supply is upgraded from a fixed-value resistor to an electronic load module. Not only can the load change according to a certain rule during the aging process, but also functions such as the no-load voltage, loaded voltage, overcurrent protection, and short-circuit protection of the mine power supply can be verified in real time. It can reflect the state of the mine power supply during the aging process in real time, and the location of unqualified products and unqualified items can be reflected through the display screen.

[0038] In the present invention, a universal transfer interface is made for different mine power supplies. The mine power supply is consigned to the corresponding aging workstations through the conveying mechanism and the consignment mechanism to realize automatic docking power supply and aging functions.

[0039] When serious abnormal situations occur during the aging process of the mine power supply, the system can actively detect faults and implement protection measures to ensure the safety and reliability of the system and avoid safety accidents. This function is mainly used for the automatic handling of abnormal situations during the aging process of the mine power supply under unattended conditions.

[0040] The aging system uploads the measured aging data of the mine power supply to the server for storage through relevant equipment, supporting a series of operations such as remote traceability query and printing by relevant personnel such as R & D and quality management, facilitating the analysis of product working characteristics and quality traceability.

[0041] The present invention has the following advantages:

[0042] (1) Adopting a platform-based design, it realizes the full automation of the mine power supply and can operate automatically under unattended conditions; it realizes the automatic preservation of data, ensuring the authenticity of the data. The data is presented in the form of an electronic spreadsheet, fully realizing paperless office and improving production efficiency.

[0043] (2) It meets the comprehensive understanding of various parameters of the mine power supply products by scientific research personnel, facilitating the analysis and summary of test data;

[0044] (3) It effectively avoids production and debugging personnel from operating high-voltage alternating current, ensuring the physical safety of operators;

[0045] (4) The whole set of systems adopts a wireless local area network communication method, and the mine power supplies are stored in a shelf-type layered manner, ensuring the cleanliness of the entire production site.

[0046] (5) The system automatically operates the equipment and automatically reads various parameters of the aging power supply, eliminating manual operation of the equipment and data recording, greatly reducing production costs and improving the economic benefits of the enterprise.

The bottom is the main tray frame assembly, and the top is the battery pack mold groove plate, which is installed by bolts. The bottom of the main tray frame is provided with double positioning holes to facilitate the fixation and positioning of the tray frame and the tray, preventing position deviation. There is a junction box on the reverse side of the tray bottom, and there are copper contact pieces on the junction box.

[0100] Aging unit

[0101] The aging unit is used to fix the test unit, and the overall structure form is guided by a pin shaft. A proximity switch is used on the bottom surface of the tray plate to detect whether there is material (mine-used power) on the tray and whether it is in place. The external dimension of the tray plate is 600x430mm (length * width). During the falling process of the test unit, it is positioned by the positioning pins on the surface of the tray plate, and then the copper contact pieces of the junction box are in contact with the probes of the power supply board of the aging unit to complete the docking of electrical signals.

[0102] Combined Figures 1 - 11 As shown, the automatic aging method for mine-used power of the present invention is as follows:

[0103] Step 1: The piggyback AGV conveying mechanism 3 transports the mine-used power 7 carried by the mine-used power carrier tray 2 from the production line to the automatic aging line for mine-used power. When the mine-used power 7 is conveyed to the end of the feeding conveyor belt 31, the correction rotating disk 33 drives the mine-used power carrier tray 2 to make a 90-degree turn. After the aging line induction device senses that there is mine-used power, the rail-mounted RGV conveying mechanism 4 is first started to transfer the mine-used power 7 from the piggyback AGV conveying mechanism 3 to the double-directional fork assembly 40. The rail-mounted RGV conveying mechanism 4 drives the mine-used power 7 to translate along the track. The motor drives the two gear sets 408 to drive through the pulley group 402. The gear set 408 drives the rack 409 to move, so that the middle fork body 404 extends forward along the lower fork body 403. The middle fork body 404 drives the upper fork body 405 to extend forward along the middle fork body through the first sprocket group 4010. The upper fork body 405 makes the plug board 406 extend forward through the second sprocket group 4012. Then, the lifting motor 45 drives the fork bracket 44 to descend along the lifting track 49 through the lead screw assembly 46, so that the copper contact pieces of the junction box 23 at the bottom end of the mine-used power carrier tray 2 are in contact with the probes of the power supply board 522 of the aging unit to complete the docking of electrical signals, thereby realizing the grasping and transfer of the mine-used power carrier tray, and towing the mine-used power 7 to the corresponding aging unit 52 according to the pre-set placement sequence.

[0104] Step 2: Towing each mine-used power to be aged entering the aging line area to the corresponding aging unit according to the above method.

[0105] Step 3: After the mining power supply is placed, the system starts the pre-configured aging process, starts to supply alternating current to the mining power supply one by one, and tests parameters such as its working current and output voltage. If any abnormal situation is found during the test, the aging of the corresponding mining power supply will be stopped immediately. The system cuts off the power supply and gives the specific location of the faulty mining power supply and alarms. Manually control the rail-type RGV handling mechanism to remove the faulty mining power supply from the aging unit.

[0106] Step 4: After there is no abnormal phenomenon in the power-on test, the system will run the regular aging process. The input AC voltage fluctuates regularly, the electronic load module detects the DC output voltage value in real time, and gives different load sizes regularly at the same time, and detects the output voltage value of the mining power supply. At the same time, the over-current protection and short-circuit protection functions of the DC output of the mining power supply are tested.

[0107] Step 5: During the aging cycle of the mining power supply, the system monitors all aging parameters of the mining power supply in real time during the aging process. When an abnormal situation occurs, an alarm signal is given in real time and accident avoidance measures are started to prevent accidents from happening.

[0108] Step 6: After aging is completed, the system controls the rail-type RGV handling mechanism to sequentially transport the mining power supply from the aging unit to the aging exit of the aging line. At this time, the back-mounted AGV conveying mechanism transports the mining power supply to the factory inspection unit for factory inspection. The entire aging process is completed.

[0109] Among them, after the mining power supply enters the aging line, the system will perform a two-dimensional code scanning operation on it, read its relevant information, bind its information to the aging unit, and store the data read during the aging process into the whole machine information corresponding to this station.
