Description

Technical Field

[0001] The invention belongs to the technical field of lead-carbon battery production, and in particular relates to lead-carbon battery processing welding equipment and a welding method. Background Art

[0002] Lead-carbon battery is a new type of super battery. It is a technology evolved from traditional lead-acid batteries. It adds activated carbon to the negative electrode of the lead-acid battery, which can significantly improve the life of the lead-acid battery.

[0003] In the production process of lead-carbon batteries, welding technology is needed. For example, when welding batteries, the positive and negative electrodes and connecting plates of the battery are welded, which requires the use of welding equipment.

[0004] Existing welding equipment, when welding, is based on heating and pressurizing to cause plastic deformation and melting of metal materials, and then achieves the connection of metal materials through cooling, solidification and bonding. For example, when a spot welder is welding, it uses the resistance heating generated by the current at the contact point to melt the surface of the workpiece. When a laser welder is welding, it is a high-energy density welding method that focuses the laser beam on the welding point to quickly heat and melt the metal surface, and then achieves the connection of the material.

[0005] Therefore, the following problems exist in the current welding process:

[0006] 1. The above welding processes will generate high heat. If the welding temperature is too high due to operating errors, too long welding time or other unexpected situations, it may cause the battery cell to short-circuit. Once the battery short-circuits, the battery will generate a large amount of current and even cause fire, explosion and other dangers, which is less safe.

[0007] 2. The loss of heat generated during the welding process.

[0008] 3. After welding, the welding part of the battery is still at a relatively high temperature and needs to be naturally cooled to room temperature before the next process can be carried out, which results in low work efficiency.

[0009] 4. During the welding process, if there is a problem with the welding and the operator needs to observe the welding situation closely, the existing welding equipment is not equipped with protective measures, and the operator does not wear protective equipment. Direct entry can easily cause harm to the operator.

[0010] 5. When the operator directly enters the equipment to view the welding situation, he can only view the welding situation with the naked eye. The weld quality, welding size, etc. involved in the welding cannot be directly obtained, which is not convenient for quickly analyzing and judging the current welding problems.

DETAILED DESCRIPTION

[0050] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0051] like Figure 1 to Figure 6 As shown, a lead-carbon battery processing welding equipment and welding method in one embodiment of the present invention is a lead-carbon battery processing welding equipment, a lead-carbon battery is placed on the welding equipment housing 1, and the welding equipment includes a welding equipment housing 1, a welding assembly 2, an explosion-proof device 9, a preheating device 3, a fire extinguishing system, a cooling device 6, an explosion-proof device and a heat absorption device 8. The welding equipment housing 1 is provided with a control screen 4, a keyboard storage drawer 401, a workbench 14, an entrance 12 and an exit 13. When welding, enter through the entrance 12 to perform welding. After welding, unload from the exit 13 or enter the next process.

[0052] The welding assembly 2 is located on the upper end surface of the welding equipment housing 1. The welding assembly 2 includes a welding head assembly 201, a welding head 202 and a screw module 203. The welding head assembly 201 moves on the screw module 203, thereby controlling the movement of the welding head 202 to weld the lead-carbon battery 10.

[0053] The heat absorbing device 8 is fixedly connected to one side end surface of the welding head assembly 201 . The heat absorbing device 8 includes a plurality of heat absorbing heads 802 . The heat absorbing heads 802 match the welding heads 202 . The heat absorbing heads 802 absorb the heat generated during the welding of the lead-carbon battery 10 .

[0054] The bottom end surface of the heat absorbing head 802 is fixedly connected with a protective sleeve, and the material of the protective sleeve is preferably silicone. While the heat absorbing head 802 absorbs heat from the welding part on the lead-carbon battery 10, under the effect of the protective sleeve, even if the heat absorbing head 802 is attached to the end surface of the lead-carbon battery 10, it will not cause damage to the lead-carbon battery 10.

[0055] The heat absorbing device 8 also includes a heat absorbing conveying plate 801, a heat absorbing pipe 803 and a negative pressure device. The heat absorbing conveying plate 801 is located at one side end face of the welding head assembly 201, that is, when the welding head 202 is welding the lead-carbon battery 10, the mobile base 901 drives the lead-carbon battery 10 to move forward, and the heat absorbing conveying plate 801 is fixed to the side end face of the welding head 202 close to the end of the welding of the lead-carbon battery 10, so that when the welding of the lead-carbon battery 10 is completed, the mobile base 901 drives the lead-carbon battery 10 to move forward to a position convenient for the next welding. At this time, the heat absorbing head 802 is located at the weld where the welding of the lead-carbon battery 10 is completed, and the heat absorbing head 802 absorbs heat from it, thereby collecting its heat. Of course, the heat absorbing device 8 will not affect the normal high-temperature welding work of the welding head 202 when absorbing heat.

[0056] A first threaded hole is provided on the heat absorbing and conveying plate 801 and the welding head 202 , and a bolt 804 is threadedly connected to the first threaded hole. The bolt 804 passes through the heat absorbing and conveying plate 801 and the welding head assembly 201 to fix the heat absorbing and conveying plate 801 on one side end surface of the welding head assembly 201 .

[0057] A heat absorbing pipe 803 is connected to one end face of the heat absorbing conveying plate 801, and a plurality of heat absorbing heads 802 are fixedly connected to the bottom end face of the welding head assembly 201, and the heat absorbing pipe 803 is in communication with the heat absorbing heads 802. The negative pressure device is connected to the heat absorbing pipe 803, and the negative pressure device is located at the bottom end face of the inner wall of the welding equipment housing 1, that is, the negative pressure device is installed at the bottom end face of the welding equipment housing 1 located at the workbench 14. When the negative pressure device is started, negative pressure can be delivered into the heat absorbing pipe 803 to absorb the heat on the lead-carbon battery 10, and the heat is delivered to the preheating device 3 through the delivery pipe to preheat the lead-carbon battery 10 at the bottom end face of the preheating device 3 to be welded.

[0058] Among them, the negative pressure device is preferably a negative pressure pump.

[0059] Ginseng Figures 4 to 8 As shown, the preheating device 3 is located between the inlet 12 of the welding equipment housing 1 and the welding assembly 2, that is, the preheating device 3 is located on one side end surface of the inlet 12, and the preheating device 3 absorbs the heat generated by the welding head 202 during welding and transmits it to the lead-carbon battery 10 located on the bottom end surface of the preheating device 3 for preheating;

[0060] The preheating device 3 includes a protective seat 301, a first lifting mechanism 302 and a working cover 304. The protective seat 301 is fixedly connected to a side end surface of the workbench 14 near the entrance 12. The first lifting mechanism 302 is fixedly connected to the upper side end surface of the protective seat 301, and a fixing seat 307 is fixedly connected to the top end surface of the first lifting mechanism 302. The working cover 304 is fixedly connected to the bottom end surface of the fixing seat 307. The first lifting mechanism 302 controls the lifting and lowering of the fixing seat 307, thereby driving the lifting and lowering of the working cover 304 to adapt to the height of the lead-carbon battery 10.

[0061] The working cover 304 matches the movable base 901 , that is, the inner wall end surface of the working cover 304 surrounds the outer end surface of the movable base 901 , thereby covering the welding position of the lead-carbon battery 10 on the movable base 901 .

[0062] A plurality of preheating nozzles 305 are arranged on the bottom end surface of the working hood 304 contacting the movable base 901, and the preheating nozzles 305 are connected to the preheating medium pipes 308, and the preheating medium pipes 308 are connected to the negative pressure pump of the heat absorption device 8, so that the heat adsorbed by the negative pressure pump is transferred to the working hood 304, and the heat absorbed by the preheating nozzles 305 is sprayed to preheat the welding parts of the lead-carbon battery 10. While reducing heat loss, it can also reduce the welding time required for the welding head 202 during welding, so that the welding time of the welding head 202 is shorter than that of the existing welding, and the efficiency is higher, which is energy-saving and environmentally friendly.

[0063] In addition, during the welding process, it is necessary to ensure that there is no dust or other dirt on the welding part of the lead-carbon battery 10. If there is dust, the battery will have poor contact, welding leakage, etc., which will affect the service life of the battery. Therefore, while the preheating nozzle 305 delivers the preheating wind, it will also blow hot air to the welding part under the action of the wind to ensure the cleanliness of the lead-carbon battery 10 welding part.

[0064] The dust removal system includes a dust suction hole 306, a dust suction pipe 303 and a dust suction device. Multiple side wall end faces of the working cover 304 are provided with multiple dust suction holes 306, that is, multiple dust suction holes 306 are located at the bottom end face of the preheating nozzle 305, and the distance between the dust suction hole 306 and the preheating nozzle 305 is 3 to 7 cm, so that the dust suction work of the dust suction hole 306 is not affected when the preheating nozzle 305 is preheating.

[0065] The dust suction hole 306 is connected to a dust suction pipe 303, which penetrates the protective seat 301, and is connected to a dust suction device, which is fixedly connected to the bottom end surface of the inner wall of the welding equipment housing 1. The dust suction device delivers negative pressure through the dust suction pipe 303 to absorb the dust swept by the preheating output wind of the preheating nozzle 305, thereby ensuring the cleanliness of the working environment.

[0066] Specifically, the first lifting mechanism 302 is started to control the working cover 304 to descend to the top end face of the working cover 304. The preheating nozzle 305 is located 1 to 3 cm from the position where the lead-carbon battery 10 needs to be welded for preheating. When the mobile base 901 carries the lead-carbon battery 10 into the bottom end face of the working cover 304, the preheating nozzle 305 outputs heat for preheating. During the preheating, the wind force output by the preheating nozzle 305 blows away the dust at the position where the lead-carbon battery 10 needs to be welded. At this time, the working cover 304 wraps part of the end face of the lead-carbon battery 10. During the preheating, the dust removal system is started, and the dust swept by the preheating nozzle 305 is adsorbed through multiple dust suction holes 306 for recovery. After the preheating is completed, the working cover 304 is reset.

[0067] A transmission mechanism is provided on the welding equipment housing 1, and the transmission mechanism includes a plurality of movable bases 901. The lead-carbon battery 10 is carried on the plurality of movable bases 901, so as to control the lead-carbon battery 10 to perform welding work.

The projection of the explosion-proof device on the horizontal plane is larger than the projection of the lead-carbon battery on the horizontal plane. The explosion-proof device can be used to wrap the lead-carbon battery 10 when the battery explodes during welding, thereby reducing the damage to surrounding operators or objects caused by the explosion of the lead-carbon battery 10 and improving safety performance.

[0069] The size of the mobile base 901 is adapted according to the size of the battery to be processed, and the size of the mobile base 901 is fixed when it leaves the factory. The size of the mobile base 901 can be customized according to the needs.

[0070] The explosion-proof device includes an explosion-proof airbag 903, which surrounds the outer end surface of the mobile base 901. Further, the middle end surface of the mobile base 901 is connected to a storage component 902, and the inner end surface of the storage component 902 is provided with a storage groove, and the explosion-proof airbag 903 is fixedly connected in the storage groove, and the explosion-proof airbag 903 protrudes from the top end surface of the storage component 902.

[0071] An inflation system is provided on the inner end face of the storage component 902, and the inflation system is connected to the explosion-proof airbag 903, wherein the inflation system includes a gas generator. When the inflation system receives an inflation command, the gas generator will generate a large amount of gas, and the gas will expand rapidly and fill the explosion-proof airbag 903, so that the explosion-proof airbag 903 will pop out quickly to wrap the lead-carbon battery 10.

[0072] The top end surface of the mobile base 901 is provided with a first smoke sensor and a first temperature sensor, and the inflation system, the first smoke sensor and the first temperature sensor are all connected to a control system. Before the lead-carbon battery 10 explodes, the heat inside the lead-carbon battery 10 will rise rapidly or produce white smoke. At this time, the first temperature sensor located at the bottom end surface of the mobile base 901 detects and the first smoke sensor sends a signal back to the control system, and the control system controls the inflation system to start and control the explosion-proof airbag 903 to expand rapidly to wrap the lead-carbon battery 10.

[0073] Preferably, the explosion-proof airbag 903 is made of TPEE or TPU.

[0074] The fire extinguishing system is located on multiple end faces of the inner wall of the welding equipment housing 1. The fire extinguishing system includes a fire extinguishing storage tank. Inert gas is stored in the fire extinguishing storage tank. When the lead-carbon battery 10 catches fire, the fire extinguishing system can quickly extinguish the fire, thereby reducing the damage caused by the fire.

[0075] The inert gas is preferably nitrogen.

[0076] The fire extinguishing system also includes a plurality of fire extinguishing delivery pipelines 7, a plurality of first fire extinguishing nozzles 701 and a sensor control system. The fire extinguishing storage tank is located at the bottom end surface of the inner wall of the welding equipment housing 1, and the fire extinguishing storage tank is connected to a plurality of inert gas delivery pipes, some of which are connected to the fire extinguishing delivery pipelines 7, and the plurality of fire extinguishing delivery pipelines 7 are all located at a plurality of end surfaces inside the welding equipment housing 1;

[0077] A plurality of first fire extinguishing nozzles 701 are fixedly connected to the top end surface of the welding equipment housing 1, and the first fire extinguishing nozzles 701 are connected to the fire extinguishing delivery pipeline 7. The inert gas in the fire extinguishing delivery pipeline 7 is sprayed out through the plurality of first fire extinguishing nozzles 701 to quickly extinguish the fire.

[0078] The sensor control system includes a second temperature sensor and a second smoke sensor. The second smoke sensor and the second temperature sensor are both distributed on the top end surface of the inner wall of the welding equipment housing 1. The second temperature sensor and the second smoke sensor are connected to a control system.

[0079] The installation position of the sensor control system is different from the installation positions of the first temperature sensor and the first smoke sensor of the explosion-proof device 9. The sensor control system is installed on the top end surface of the inner wall of the welding equipment housing 1, so that when a fire source appears at other positions in the welding equipment housing 1, it can be detected in time and the fire can be extinguished quickly and efficiently.

[0080] The fire extinguishing system also includes a plurality of second fire extinguishing nozzles 702. The workbench 14 is provided with a plurality of limiting holes on the peripheral end surface of the welding assembly 2.

The cooling device 6 also includes a second lifting mechanism 601, and a top plate 602 is fixedly connected to the top end surface of the second lifting mechanism 601, and a cooling plate 604 is fixedly connected to the bottom end surface of the top plate 602, and a plurality of cooling nozzles 605 are arranged on the bottom end surface of the cooling plate 604, and the cooling plate 604 is connected to a gas delivery pipeline 603, and the gas delivery pipeline 603 is connected to an inert gas delivery pipe.

[0083] Specifically, the cooling device 6 first adjusts the distance between the cooling plate 604 and the top end face of the battery to 3 to 8 cm according to the height of the battery. After the welding of the lead-carbon battery 10 is completed, the mobile base 901 drives the lead-carbon battery 10 to enter the bottom end face of the cooling plate 604. At this time, the fire extinguishing storage tank starts to transport inert gas through the gas delivery pipe 603 into the cooling plate 604 and sprays it through multiple cooling nozzles 605 to quickly and effectively cool the welding part of the lead-carbon battery 10.

[0084] It should be noted that the first lifting mechanism 302 and the second lifting mechanism 601 have the same structure, and are both structures that can control the lifting of the fixed seat 307 or the top plate 602. Preferably, the first lifting mechanism 302 and the second lifting mechanism 601 include a driving motor, a reduction gear and a screw. The lifting of the screw is controlled by the driving motor to achieve the purpose of controlling the lifting of the object. Of course, the first lifting mechanism 302 and the second lifting mechanism 601 can also be structures well known in the art such as elevators and cylinders to achieve the purpose of controlling the lifting.

[0085] A storage drawer 5 is provided on one side end surface of the welding equipment housing 1. A protective mask 11 is stored in the storage drawer 5. When the protective mask 11 is needed, the protective mask 11 can be taken out of the storage drawer 5 and worn.

[0086] One side end face of the protective mask 11 is provided with a protective screen 1101 which is rotatably connected, and a transparent information display screen is attached to the inner wall end face of the protective screen 1101. One side end face of the transparent information display screen is connected to an information processor, and the information processor is located on one side end face of the protective mask 11, and the information processor is connected to the control system.

[0087] At present, welding equipment includes weld self-awareness recognition systems, mechanical sensors and visual sensors, which can automatically detect and identify welding conditions such as appearance, size, temperature, etc. during the welding process, and monitor welding quality problems. When problems occur, the equipment will send a warning signal through the alarm, and the operator will take corrective measures to improve welding quality, efficiency and safety.

[0088] Specifically, when the operator needs to enter the welding equipment housing 1 to view the current welding situation, the protective mask 11 can be worn on the head, and then enter the welding equipment housing 1 to view the current welding situation, so as to protect the operator from being injured by welding. At the same time, unlike the prior art, the welder can only watch with the naked eye and cannot quickly judge the current welding problem.

[0095] like Figure 7 As shown, the first lifting mechanism 302 is started to control the working cover 304 to descend to an adaptive height that matches the current lead-carbon battery 10. When the mobile base 901 drives the lead-carbon battery 10 to enter the bottom end surface of the working cover 304, the preheating nozzle 305 is started to output hot air recovered from the heat absorption device 8 to preheat and clean the dust at the welding part of the lead-carbon battery 10.

[0098] After the lead-carbon battery 10 enters the bottom of the welding head 202 for welding, the mobile base 901 drives the lead-carbon battery 10 to move forward after each welding is completed. At this time, the heat absorption head 802 is facing the welding point of the lead-carbon battery 10 where welding is completed. The negative pressure device starts to transmit negative pressure through the heat absorption pipe 803, and absorbs the heat of the welding point where the current welding is completed through the heat absorption head 802, and transmits it to the preheating device 3 to preheat the next battery.

[0099] S6, cooling; after the welding of the lead-carbon battery currently being processed is completed, the mobile base 901 drives the lead-carbon battery 10 into the bottom end face of the cooling device 6 to quickly cool down the welding part on the lead-carbon battery. After the cooling is completed, the mobile base 901 drives the lead-carbon battery 10 into the outlet 13 for the next process.

[0100] like Figure 8 As shown, after the welding of the lead-carbon battery 10 is completed, the mobile base 901 drives the lead-carbon battery 10 to enter the bottom end surface of the cooling plate 604. At this time, the fire extinguishing storage tank starts to transport inert gas through the gas delivery pipe 603 into the cooling plate 604 and is sprayed through multiple cooling nozzles 605 to quickly and effectively cool the welding point of the lead-carbon battery 10.
