Description

Technical Field

[0001] The present invention belongs to the field of electromechanical application technology, and specifically relates to an integrated intelligent welding material warehouse for realizing welding rod baking, heat preservation, transportation and distribution. Background Art

[0002] In the field of welding technology, when welders use welding rods for welding, they often need to preheat the welding rods to a specified temperature in order to ensure that the welding quality meets the requirements. The existing technology usually preheats a batch of welding rods to a certain temperature, and then temporarily stores the heated welding rods in an insulated box. When welding, the welding rods are taken out of the insulated box, and the use requires manual application, review, and registration. At present, most welding rod issuance processes require complicated manual review procedures and manual review before issuance, which requires the participation of multiple people and wastes a lot of manpower; some companies use mechanical issuance, but the issuance equipment only has the function of heat preservation issuance. The management personnel need to manually transfer the baked qualified welding rods to the equipment issuance warehouse for heat preservation. After the welder applies, he can use his face to receive the welding rods, and cannot return the materials; and the existing equipment is single-channel, and only one welder can receive the welding rods at a time, and multiple people cannot operate at the same time. The problems it has are: (1) The manual transfer process of high-temperature welding rods not only affects work efficiency, but also poses a risk to the safety of operators; (2) Each time it needs to be manually added, there is a possibility of placement errors, which will cause welding quality problems in the later stage.

[0053] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] like Figures 1 to 3 An integrated intelligent welding material warehouse includes a storage area 3.8 and an equipment area 3.1. The equipment area 3.1 is composed of an oven 3.7, a material taking mechanism 3.6, a transfer mechanism 3.2, a distribution warehouse mechanism 3.3, a material unloading mechanism 3.4, and a recycling mechanism. Figure 2 and 3 The whole equipment is located in a 12×2.4×2.5 (length×width×height) compartment, and the storage area is separated from other parts of the equipment area by an oven.

[0055] Storage area: A set of four-layer standard shelves 3.10 with dimensions of 2 meters wide × 2 meters high × 0.6 meters deep are installed in the storage area 3.8. The shelves are 0.3 meters away from the wall and the ground to prevent moisture from getting into the welding materials during storage. An LCD screen 3.11 is hung on the wall to display the status of welding rods entering and leaving the warehouse and the progress of project use in real time. A set of electronic temperature and humidity recorders are installed in the storage area to communicate with the equipment control system to monitor the temperature and humidity status of the equipment. A semi-automatic stacker is equipped in the storage area to assist the administrator to take out the welding rod trays on the trolley in the oven and manually replenish the welding rods before putting the trays on the trolley of the oven.

[0056] like Figures 4 to 6 , Oven: Oven 3.7 is a double-chamber double-side door opening mechanism, the equipment side is an automatic door, and the storage side is a manual door; a fixed pallet trolley 4.5 is installed in each cavity, and each pallet trolley 4.5 is equipped with seven layers of removable welding rod trays 4.4, and a certain amount of welding rods can be stored in the welding rod trays 4.4; the heated air is forced to circulate in the oven through the fan on the top, so that the hot air is fully in contact with the material to be dried, thereby achieving rapid and uniform heating and drying. When refilling, the administrator manually opens the oven door on the storage side, uses an electric stacker to take out the welding rod tray 4.4 in the oven, and places a certain amount of welding rods into the welding rod tray 4.4. After placing them, the welding rod tray 4.4 loaded with welding rods is placed on the pallet trolley 4.5 in the oven. After completing the welding rod refilling, press the start button on the equipment control box, and the oven will automatically heat up according to the program set by the software. After the baking program is completed, it will enter the insulation state and standby. When the oven receives the material taking signal, the door on the oven equipment side will automatically open. The automatic opening method is that the door locking electric cylinder 4.8 on the oven door extends back to drive the horn lock door shaft to rotate and disengage the locking seat, and then the door flat opening electric cylinder 4.7 retracts to drive the door to open through the hinge, and then waits for the material taking mechanism to take away the specified welding rod tray before automatically closing the oven door.

[0057] like Figure 7, Material picking mechanism: The main functions of this mechanism are: (1) The material picking arm 7.4 (the existing three-stage telescopic fork can be used) extends and rises to a certain height and then retracts to take out the welding rod tray 4.4 on the trolley in the oven, and then transfers it to the transfer mechanism. After the gripper 10.7 of the transfer mechanism takes out the welding rod in the welding rod tray 4.4, the material picking arm 7.4 of the material picking mechanism puts the empty tray back on the tray trolley 4.5 of the oven. (2) Adjust the stacking of welding rod trays in the two chambers of the oven to ensure that the start time of welding material baking is in the optimal state. The material picking mechanism consists of three parts: X-axis horizontal transmission, Z-axis vertical transmission and Y-axis material picking arm front and rear transmission. The X-axis transmission consists of two horizontally symmetrical linear X-axis guide rails 7.12 and gear rack 7.11. The material picking mechanism can move left and right between the two chambers of the oven through the X-axis servo drive 7.5. The X-axis horizontal transmission is controlled by a servo motor for precise positioning. The Z-axis vertical transmission is that the entire lifting mechanism is assembled into a gantry frame 7.10 by four square tube profiles. At the top of the frame, the Z-axis servo drive 7.1 drives the sprocket 7.7 and the chain 7.6 so that the platform in the gantry frame can be lifted and lowered. The material-retrieving arm in the platform can move in the vertical direction of the Z-axis and retract to retrieve and place the welding rod tray 4.4 at any height in the oven cavity. The platform is welded by square tube profiles. The retraction of the material-retrieving arm in the platform is through multi-stage synchronous retraction, which can extend the arm into the oven, take out the tray loaded with materials from the high-temperature oven and accurately place it on the transfer mechanism platform, then retrieve the empty tray from the transfer mechanism platform, and finally place the empty tray in the oven.

[0058] like Figure 8 and 9 ,Transfer mechanism: The main function of this mechanism is to grab the welding rods in the fully loaded tray on the transfer mechanism into the designated distribution bin according to the specified procedure according to the control signal. The mechanism consists of an X-axis transmission mechanism, a tray horizontal steering mechanism, a welding rod lifting mechanism, a welding rod grabbing mechanism, and a Y-axis transmission mechanism. The transfer mechanism and the material-retrieving mechanism are perpendicular to each other, and the transfer mechanism can move back and forth between the material-retrieving mechanism and the six distribution bins. After the material-retrieving arm places the tray on the transfer platform, the transfer platform drives the rotating gear plate 10.11 to rotate 90 degrees through the gear on the W-axis servo rotary drive 10.12. After the rotation of the welding rod tray is completed, the welding rod lifting arm 10.8 is driven to rise through the Z-axis servo electric cylinder 10.10 and lifts the welding rods in the tray. The two groups of lifting arms are lifted separately. After one group of welding rods is lifted, the gripper grabs the welding rods and moves them to the designated distribution bin through the Y-axis servo module 10.5 for feeding. Only after the feeding is completed can the other group of welding rods be lifted. The horizontal movement, tray turning, welding rod lifting, welding rod grabbing and gripper moving mechanism of the structure are all completed by the cooperation of different motors.

[0059] like Figures 10 to 17, Automatic dispensing bin mechanism: This mechanism consists of six independent dispensing bins, and its main functions are: (1) automatic heating and heat preservation, so that the welding rods being dispensed are always at a temperature that meets the requirements; (2) the dispensing bin has a heat preservation layer and hot air circulation function; (3) automatic counting function during dispensing. This mechanism mainly consists of a heat preservation heating rod 12.3, a hot air circulation motor 12.4, a dispensing bin cavity 12.1 with a heat preservation layer, an automatically opening and closing bin cover 12.5, a welding material reciprocating lifting mechanism, and a material unloading mechanism. The heat preservation heating rod 12.3 is located at the bottom of the dispensing bin cavity 12.1. The temperature sensor in the bin feeds back the analog quantity to the PLC to control the output voltage of the heating rod to ensure the temperature in the bin, so that the temperature in the bin is always within the specified temperature range. The upper part of the dispensing bin is a bin cover 12.5 that can be opened and closed automatically. The bottom of the cavity 12.1 in the dispensing bin has a certain inclination angle and is hollowed out. There are also slots on the side to facilitate heat circulation and transfer. The five surfaces of the dispensing bin and the cavity are filled with insulation materials to ensure the temperature in the bin. A welding rod lifting mechanism is arranged at the outlet of the cavity in the dispensing bin. The welding rod lifting mechanism adopts a multi-layer stepping lifting structure. When the motor rotates to drive the cam bearing on the eccentric shaft to rotate eccentrically, the cam bearing is in the cam bearing slide groove, and the movable push plate base is fixed on the linear bearing, so that the movable push plate base reciprocates up and down. Five movable push plates are fixed on the base of the movable push plate and clamped in the middle of the fixed plate, so that the movable push plate reciprocates up and down to lift the welding rod to move up in a step-by-step manner, and finally push the welding rod out of the upper edge. The welding rod rolls out of the discharge port from the slope through free fall, and the counting sensor under the slope counts while rolling out. The up and down reciprocating stroke is determined by the spacing of the eccentric shafts of the cam bearings. The number of single rods to be pushed is determined by the thickness of the movable push plate, which is 6mm thick and the spacing of the fixed plates is also 6mm. Each time the movable push plate descends, it is 1mm higher than the fixed plate, thereby ensuring the discharge of one rod and being compatible with products between 3.5-8mm. The ejected welding rod slides from the ejection outlet into the hopper 14.2 of the unloading mechanism. When the discharge is completed, the material picker holds the handle 14.7 and rotates the translation hopper 14.2 and then presses the hopper down at a certain angle, and the welding rod can slide into the welding rod insulation barrel.

[0060] like Fig.18 Automatic recycling machine: The main function of this mechanism is to recycle the remaining welding rods and count them. After receiving the command, the electromagnetic lock 15.2 will automatically pop out the recycling bin door 15.1. The welder puts the remaining welding rods into the recycling port. The welding rods will fall freely into the recycling bin due to gravity. The sliding process will be sensed by the counting sensor and counted.

[0061] How this integrated intelligent welding material library works:

[0062] (1) Preparation for use: Before use, the administrator completes the equipment settings through the supporting software. The settings include the baking temperature and time requirements of the oven, the parameter information of the 14 trays in the oven, the parameter information and temperature of the 6 automatic distribution bins, etc.

[0063] (2) Material entry: The administrator registers the welding materials through the supporting software and places the relevant materials on the shelves in the storage area in order as required.

[0064] (3) Loading: The administrator uses the electric auxiliary stacker to take out the trays in the oven one by one, place the corresponding welding rods according to the set parameters and specifications, and arrange them as a whole. Usually 100kg of welding rods are placed at a time. After each oven cavity is filled, close the manual door at the front of the oven, press the start button, and the heater and circulating fan in the baking oven will start. The oven will automatically run according to the parameters set in the system. When the oven is baked and enters the insulation state, if a material retrieving signal is received, the rear automatic door will automatically open and wait for the material retrieving mechanical structure to retrieve the material. After the material retrieving is completed, the door will automatically close, and when the empty tray is returned, the door will automatically open.

[0065] (4) Transfer: The material picking mechanism and the transfer mechanism wait at the origin of the equipment. When the system gives a signal to add welding rods to the automatic dispensing bin, the material picking mechanism will move to the corresponding baking oven according to the information in the system, lift the material picking tray to the corresponding tray position, extend it into the baking oven, take out the corresponding tray, and place it on the transfer mechanism. After receiving the tray, the transfer mechanism starts to move to the corresponding automatic dispensing bin. During the movement, the tray automatically rotates, and the welding rod folding arm is lifted to lift the welding rod. When it reaches the designated position, the welding rod grabbing arm descends to grab the welding rod. After moving to the top of the automatic dispensing bin through the grabbing arm moving mechanism, the welding rod grabbing arm descends to place the welding rod in the automatic dispensing bin. This work is performed twice for each tray. After the welding rods are placed in the tray, the transfer mechanism returns to its original position, the material picking mechanism retrieves the empty tray, and puts the empty tray back to the designated position of the baking oven.

[0066] (5) Automatic refilling of the distribution bin: In the initial stage, the equipment will automatically send a refilling signal to the system according to the set parameters. During the continuous operation stage, the distribution bin will collect statistics based on the refilling and dispensing data. When the remaining material in the bin reaches the threshold, the system will automatically refill. The top cover of the distribution bin will automatically open when refilling and automatically close when refilling is completed.

[0067] (6) Automatic dispensing from the dispensing bin: The welder applies for dispensing through the supporting procedures. After the review is completed, he goes to the machine for face verification. After the verification is passed, the automatic dispensing mechanism automatically starts dispensing according to the applied quantity. The welding rod passes through the dispensing port and slides into the receiving hopper through the contact sensor. When the dispensing is completed, the LED screen at the front of the equipment shows the dispensing. The welder rotates the dispensing hopper 90°, aligns the welding rod barrel with the dispensing port, and presses down the dispensing hopper. The welding rod automatically slides into the welding rod barrel. The welder returns the dispensing hopper to its original position, and the reset sensor returns the data after receiving the signal. The entire dispensing process is completed.

[0068] (7) Automatic recycling: The welder applies for the return of unused welding rods through the supporting software. After the application is completed, he goes to the designated bin to scan his face. After the verification is passed, the recycling bin door automatically opens. After the welder places the welding rod into the recycling bin door, the welding rod automatically slides down the ramp into the recycling bin. The sliding process is counted by the contact sensor and uploaded to the system.

[0069] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the protection scope of the present invention in any form, and all technical solutions obtained by equivalent replacement and the like fall within the protection scope of the present invention.
