Description

Technical Field

[0001] This utility model belongs to the field of electromechanical application technology, specifically relating to an integrated intelligent welding material warehouse for realizing the baking, heat preservation, transfer and distribution of welding rods. Background Technology

[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 achieve the required welding quality. The existing technology usually involves preheating a batch of welding rods to a certain temperature and then temporarily storing the preheated welding rods in an insulated box. When welding, the welding rods are taken out of the insulated box, and the use of them requires a manual application, review, and registration process. At present, most welding rod distribution processes require a complicated manual review process before distribution, which requires the participation of many people and wastes a lot of manpower; some companies use mechanical distribution, but the distribution equipment only has the function of insulated distribution. Managers need to manually transfer the preheated welding rods to the equipment distribution chamber for insulation. After the welder applies, they can use their face to collect the welding rods, and it is impossible to return the materials; moreover, the existing equipment is a single channel, and only one welder can collect the welding rods at a time, which cannot be operated by multiple people at the same time. The problems are: (1) The manual transfer of high temperature welding rods not only affects the work efficiency, but the high temperature welding rods also pose a safety risk to the operators; (2) Each time, manual addition is required, which may result in incorrect placement and welding quality problems later.

[0053] The present invention will now be described in detail 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 consists of a drying oven 3.7, a material handling mechanism 3.6, a transfer mechanism 3.2, a dispensing mechanism 3.3, a feeding mechanism 3.4, and a recycling mechanism. The overall layout of the welding material warehouse is shown in the reference diagram. Figure 2 and 3 The entire equipment is housed in a 12×2.4×2.5 (length×width×height) box, with the storage area separated from other equipment areas by an oven.

[0055] Storage Area: Storage area 3.8 is equipped with a set of four-tier standard shelving units measuring 2 meters wide × 2 meters high × 0.6 meters deep 3.10. The shelving is 0.3 meters away from the walls and the floor to prevent welding materials from getting damp during storage. A wall-mounted LCD screen 3.11 displays the real-time status of welding rods entering and leaving the warehouse, as well as the project's usage progress. An electronic temperature and humidity recorder is installed in the storage area, communicating with the equipment control system to monitor the temperature and humidity status of the equipment. A semi-automatic stacker truck is also provided in the storage area to assist the administrator in removing welding rod pallets from the trolley inside the drying oven, manually replenishing the welding rods, and then placing the pallets back onto the trolley inside the drying oven.

[0056] like Figures 4 to 6 The drying oven (3.7) is a double-chamber, double-sided door system. The equipment side has an automatic door opening and closing mechanism, while the storage side has a manual door opening and closing mechanism. Each chamber is equipped with a fixed pallet cart (4.5), and each pallet cart (4.5) has seven layers of removable welding rod trays (4.4). Each welding rod tray (4.4) can hold a fixed quantity of welding rods. A top-mounted fan forces heated air to circulate within the oven, ensuring thorough contact between the hot air and the material to be dried, thus achieving rapid and uniform heating and drying. When replenishing materials, the administrator manually opens the oven door on the storage side, uses an electric stacker to remove the welding rod trays (4.4) from the oven, places the required quantity of welding rods into the trays (4.4), and then places the trays (4.4) back onto the pallet carts (4.5) inside the oven. After replenishing the welding rods, the start button is pressed on the equipment control box. The oven will automatically heat up according to the software-set program. After the baking program is complete, it will enter a heat preservation state and wait for further operation. When the oven receives the material picking signal, the door on the side of the oven equipment will open automatically. The automatic opening method is that the door locking electric cylinder 4.8 on the oven door extends back, thereby driving the horn lock door shaft to rotate and disengage from the locking seat. Then, the door opening electric cylinder 4.7 retracts and drives the door to open through the hinge. Then, the oven door will automatically close after the material picking mechanism takes away the designated welding rod tray.

[0057] like Figure 7The material handling mechanism has the following main functions: (1) The material handling arm 7.4 (which can be an existing three-section telescopic fork) extends and rises to a certain height before retracting to take out the welding rod tray 4.4 on the trolley inside the oven, and then transfers it to the transfer mechanism. After the gripper 10.7 of the transfer mechanism takes away the welding rod in the welding rod tray 4.4, the material handling arm 7.4 of the material handling 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 cavities inside the oven to ensure that the start time of welding material baking is in the optimal state. The material handling mechanism consists of three parts: X-axis horizontal transmission, Z-axis vertical transmission and Y-axis material handling 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 handling mechanism can move left and right between the two cavities 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 drive system comprises a gantry frame 7.10 assembled from four square tubular profiles. At the top of the frame, a Z-axis servo drive 7.1 drives a sprocket 7.7 and a chain 7.6, enabling the platform within the gantry frame to rise and fall. The material-retrieving arm within the platform can move vertically along the Z-axis and extend / retract to retrieve welding rod trays 4.4 at any height within the oven cavity. The platform, welded from square tubular profiles, utilizes a multi-stage synchronous extension / retraction mechanism. This allows the arm to reach into the oven, retrieve trays containing materials from the high-temperature oven, and accurately place them onto the transfer mechanism platform. Empty trays are then retrieved from the transfer mechanism platform and finally placed back into the oven.

[0058] like Figure 8 and 9 The transfer mechanism's main function is to grab welding rods from a fully loaded pallet on the transfer mechanism according to a specified program and transfer them to designated dispensing bins, based on control signals. This mechanism consists of an X-axis drive mechanism, a pallet horizontal steering mechanism, a welding rod lifting mechanism, a welding rod grabbing mechanism, and a Y-axis drive mechanism. The transfer mechanism is perpendicular to the material handling mechanism and can move back and forth between the material handling mechanism and the six dispensing bins. After the material handling arm places the pallet on the transfer platform, the transfer platform drives the rotary gear disk 10.11 to rotate 90 degrees via the gear on the W-axis servo rotary drive 10.12. After the welding rod pallet has rotated, the welding rod lifting arm 10.8 is driven upwards via the Z-axis servo electric cylinder 10.10, lifting the welding rods from the pallet. The two lifting arms lift separately. After one set of welding rods is lifted, the gripper grabs the welding rods and moves them to the designated dispensing bins via the Y-axis servo module 10.5 for feeding. Only after feeding can the other set of welding rods be lifted. The horizontal movement, tray turning, electrode lifting, electrode gripping, and gripper moving mechanism of this structure are all accomplished by different motors working together.

[0059] like Figures 10 to 17Automatic dispensing mechanism: This mechanism consists of six independent dispensing chambers. Its main functions are: (1) automatic heating and heat preservation to keep the dispensing welding rods at a specified temperature; (2) the dispensing chambers have insulation and hot air circulation functions; and (3) automatic counting function during dispensing. The mechanism is mainly composed of a heat-insulating heating rod 12.3, a hot air circulation motor 12.4, a dispensing chamber cavity 12.1 with insulation, an automatically opening and closing chamber cover 12.5, a welding material reciprocating lifting mechanism, and a feeding mechanism. The heat-insulating heating rod 12.3 is located at the bottom of the dispensing chamber cavity 12.1. The temperature sensor inside the chamber feeds back an analog signal to the PLC to control the output voltage of the heating rod, thereby ensuring the temperature inside the chamber and keeping it within the specified temperature range. The upper part of the dispensing chamber is an automatically opening and closing cover 12.5. The bottom of the dispensing chamber cavity 12.1 has a certain angle and is hollowed out. The sides also have slots to facilitate heat circulation and transfer. All five sides of the dispensing chamber cavity are filled with insulation material to ensure the temperature inside the chamber. A welding rod lifting mechanism is set at the outlet of the dispensing chamber cavity. This welding rod lifting mechanism adopts a multi-layer stepping lifting structure. When the motor rotates, it drives the cam bearing on the eccentric shaft to rotate eccentrically. Since the cam bearing is in the cam bearing groove and the movable push plate base is fixed on the linear bearing, the movable push plate base moves up and down reciprocatingly. The five movable push plates are fixed on the movable push plate base and sandwiched in the middle of the fixed plate. This causes the movable push plates to move up and down reciprocatingly to lift the welding rod and move it upward in a step-like manner. Finally, the welding rod is pushed out of the upper edge. The welding rod rolls out of the discharge port from the ramp through free fall. At the same time as it rolls out, the counting sensor below the ramp counts. The reciprocating stroke during this process is determined by the eccentric shaft spacing of the cam bearing. The number of individual welding rods pushed is determined by the thickness of the movable push plate, which is 6mm thick. The spacing between the fixed plates is also 6mm. Each time the movable push plate descends, it is 1mm higher than the fixed plates, thus ensuring that only one rod is ejected and accommodating products between 3.5-8mm in thickness. The ejected welding rod slides from the ejection outlet into the hopper 14.2 of the unloading mechanism. After unloading is complete, the operator holds the handle 14.7 and rotates the hopper 14.2 to move it horizontally, then presses the hopper down at a certain angle, allowing the welding rod to slide into the welding rod insulation container.

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

[0061] How this integrated intelligent welding material warehouse 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 baking oven, the parameter information of the 14 trays in the oven, and the parameter information and temperature of the 6 automatic dispensing compartments.

[0063] (2) Material warehousing: The administrator registers the welding materials for warehousing through the supporting software and places the relevant materials in the warehouse area in the order required.

[0064] (3) Feeding: The administrator uses an electric-assisted stacker to remove the trays from the oven one by one, places the corresponding welding rods according to the set parameters and specifications, and arranges them as a whole. Usually, 100kg of welding rods are placed at a time. After each oven cavity is full, the manual door at the front of the oven is closed, and the start button is pressed. The heater and circulating fan inside the oven start, and the oven will run automatically according to the parameters set in the system. When the oven finishes baking and enters the heat preservation state, if a material retrieval signal is received, the automatic door at the rear will open automatically, waiting for the material retrieval mechanism to retrieve the material. After the material retrieval is completed, the door will close automatically, and when the empty tray returns, the door will open automatically.

[0065] (4) Transfer: The material handling mechanism and the transfer mechanism wait at the equipment origin. When the system signals that welding rods need to be added to the automatic dispensing bin, the material handling mechanism will move to the corresponding baking oven according to the information in the system, lift the material handling tray to the corresponding tray position, extend 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 is automatically rotated and the welding rod retracting arm is raised to lift the welding rod. When it reaches the designated position, the welding rod grasping arm descends to grasp the welding rod. After moving to the top of the automatic dispensing bin through the grasping arm moving mechanism, the welding rod grasping arm descends to place the welding rod inside the automatic dispensing bin. This operation is performed twice for each tray. After the welding rods are placed in the tray, the transfer mechanism returns to the original position, the material handling mechanism retrieves the empty tray, and puts the empty tray back to the designated position in the baking oven.

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

[0067] (6) Automatic Dispensing from the Dispensing Bin: Welders apply for and receive welding rods through the corresponding procedures. After the application is approved, they undergo facial recognition verification at the machine. Once verified, the automatic dispensing mechanism starts dispensing according to the requested quantity. The welding rods slide into the receiving hopper via a contact sensor after passing through the dispensing port. When dispensing is complete, the LED screen at the front of the equipment displays the dispensing status. The welder rotates the dispensing hopper 90°, aligns the welding rod container with the dispensing port, and presses down on the dispensing hopper. The welding rods automatically slide into the welding rod container. The welder returns the dispensing hopper to its original position, and the reset sensor receives a signal and returns data, completing the entire material dispensing process.

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