Description

Technical Field

[0001] This utility model belongs to the technical field of storage battery production equipment, specifically relating to a device for automatically applying anti-rust oil to storage battery terminals. Background Technology

[0002] The terminals of storage batteries are mostly made of lead alloys. When exposed to air for a long time, they are prone to oxidation, producing corrosive substances such as lead sulfate. This leads to an increase in the contact resistance between the terminals and the connectors, affecting the battery's conductivity and service life.

[0003] Traditional rust-preventive oil application processes rely on manual operation, which has the following problems:

[0004] 1. Inefficient: Manual oiling is slow and cannot meet the high-speed requirements of modern production lines (such as processing more than 10 batteries per minute).

[0005] 2. Poor uniformity: Manual operation can easily lead to uneven oil film thickness (thickness fluctuation range can reach ±50%), which affects the rust prevention effect.

[0006] 3. Safety hazards: Rust-preventive oil contains organic solvents (such as mineral oil and corrosion inhibitors), and long-term exposure can easily cause health problems for operators.

[0007] 4. Cost waste: Manual oiling is prone to problems such as oil dripping and overuse, resulting in material waste (the waste rate can reach 20% to 30%).

[0008] Existing automated equipment mostly uses a fixed oiling structure, which is difficult to adapt to the size and shape changes of battery terminals of different specifications, and lacks precise oil volume control and coating feedback mechanisms, while achieving efficient oil utilization and harmless production process. For example, the utility model with announcement number CN214554977U discloses a terminal anti-rust oil filling device, including an oil bottle, with a bottle mouth at the top of the bottle body, and a brush head installed on the bottle mouth. The brush head has an oil outlet hole and brush bristles on its front side. The oil bottle has an air bladder hole that penetrates the bottle wall, and an air bladder is sealed at the air bladder hole. The air bladder protrudes from the bottle body, and the anti-rust oil in the oil bottle can be squeezed out by compressing the air bladder. The filling device also includes a pressure plate, which is located above the air bladder and is hinged at its tail end. Pressing down on the front end of the pressure plate can compress the air bladder. Utility Model Content

[0009] To address the aforementioned technical problems in the existing technology, this utility model provides an automatic device for applying anti-rust oil to battery terminals.

[0010] This utility model provides an automatic device for applying anti-rust oil to battery terminals. The top surface of the battery has two terminals, one of which is a positive terminal and the other is a negative terminal. The device includes:

[0011] frame;

[0012] A conveyor belt, mounted on the frame, is used to transport batteries. The frame has a mounting plate at the upstream end of the conveyor belt.

[0013] An application mechanism, mounted on the mounting plate, is used to apply anti-rust oil to the two terminals of the battery. The application mechanism includes two liftable application heads, the distance between which is adapted to the distance between the two terminals on the top surface of the battery. The application mechanism also includes an oil supply unit for supplying anti-rust oil to the application heads.

[0014] The first positioning mechanism includes a first sensor for detecting the position of the battery and a guide unit for guiding the battery to the underside of the coating mechanism. Simultaneously, the conveyor belt stops conveying after the first sensor detects the battery.

[0016] The second positioning mechanism includes a second sensor for detecting the position of the battery. When the battery is transported below the brush mechanism, the second sensor detects the battery, and the conveyor belt stops transporting.

[0017] Furthermore, the coating mechanism includes a first mounting base for mounting the coating head, and the mounting plate is provided with a first drive unit for driving the first mounting base to rise and fall, enabling the coating head to rise and fall automatically.

The metering oil extrusion nozzle can linearly extrude a metered amount of rust-preventive oil, and then the brush mechanism can be used to evenly apply the rust-preventive oil.

[0020] Furthermore, the brush mechanism includes a second mounting base, on which the brush is mounted. The mounting plate is equipped with a second drive unit that drives the second mounting base to rise and fall automatically, allowing the brush to rise and fall automatically. The second mounting base also includes a motor for driving the brush to rotate. The second drive unit can be a cylinder or a motor.

[0021] Furthermore, the first mounting base is provided with a first horizontal guide rail arranged along the conveyor belt conveying direction, and the second mounting base is provided with a second horizontal guide rail arranged along the conveyor belt conveying direction; two first mounting bases that can slide along the first horizontal guide rail are fitted on the first horizontal guide rail, and each first mounting base is provided with a coating head; two second mounting bases that can slide along the second horizontal guide rail are fitted on the second horizontal guide rail, and each second mounting base is provided with a brush. The two first mounting bases and the two second mounting bases can slide along the first horizontal guide rail and the second horizontal guide rail respectively, and the distance between the two first mounting bases and the distance between the two second mounting bases can be adjusted respectively, thereby adapting to batteries with different terminal spacings.

[0022] Furthermore, the first mounting base is provided with two first horizontal guide rails arranged side by side, and each first horizontal guide rail is provided with two first mounting bases; the second mounting base is provided with two second horizontal guide rails arranged side by side, and each second horizontal guide rail is provided with two second mounting bases; correspondingly, the first positioning mechanism includes two guide units, which are applied to two side by side batteries each time.

Detailed Implementation

[0035] like Figures 1-5 As shown, this embodiment provides an automatic device for applying anti-rust oil to battery terminals. The device includes a frame 1, a conveyor belt 2, an application mechanism 4, a first positioning mechanism 5, a brush mechanism 6, and a second positioning mechanism 7.

[0036] Conveyor belt 2 is mounted on frame 1 and is used to transport batteries. Conveyor belt 2 can be a variable frequency speed-regulating double sprocket synchronous belt conveyor line, with a conveying speed adjustable from 0.1 to 2 m / s. It is suitable for battery sizes ranging from 150 to 500 mm in length, 80 to 300 mm in width, and 100 to 400 mm in height.

[0037] A mounting plate 3 is provided on the upstream end of the conveyor belt 2 of the frame 1, and an application mechanism 4 is mounted on the mounting plate 3. The top surface of the battery has two terminals, one positive and the other negative. The application mechanism 4 is used to apply anti-rust oil to the two terminals of the battery. The application mechanism 4 includes two liftable application heads 41, the spacing of which is adapted to the spacing between the two terminals on the top surface of the battery.

[0038] The coating head 41 is either an atomizing nozzle or a metering oil dispensing nozzle. The atomizing nozzle atomizes the oil and sprays it evenly onto the terminal surface, reducing oil buildup and eliminating the need for the brush mechanism 6 to evenly spread the rust-preventive oil on the terminals. An ultrasonic atomizer can be used for the atomizing nozzle. The metering oil dispensing nozzle linearly dispenses a metered amount of rust-preventive oil, which is then evenly spread using the brush mechanism 6. Either the atomizing nozzle or the metering oil dispensing nozzle can be selected for installation and use according to actual needs. Both can also be installed simultaneously; in this case, only one can be selected, or the two coating heads 41 can be switched by rotation as needed.

[0039] The coating mechanism 4 also includes a first mounting base 42, on which the coating head 41 is mounted. A first drive unit 45 is provided on the mounting plate 3 to drive the first mounting base 42 to rise and fall automatically, enabling the coating head 41 to rise and fall automatically. The first drive unit 45 can be a motor or a cylinder. To make the rising and falling process of the first mounting base 42 more stable, two vertical guide rods 46 are provided on the mounting plate 3, and the lower ends of the two vertical guide rods 46 are respectively fixed to the first mounting base 42.

[0040] The coating mechanism 4 also includes an oil supply unit for supplying rust-preventive oil to the coating head 41. The oil supply unit includes an oil tank 43 mounted on the frame 1 and an oil pipe 44 connecting the oil tank 43 and the coating head 41. A metering pump is mounted on the oil pipe 44 and fixed to the first mounting base 42. The metering pump is preferably a gear metering pump, equipped with a piezoelectric flow sensor, and the pump speed and valve opening can be adjusted by a control system. A liquid level sensor may be built into the oil tank 43 to automatically monitor the liquid level of the rust-preventive oil within the tank.

[0041] The brush mechanism 6 is mounted on the mounting plate 3 and located downstream of the coating mechanism 4. It is used to evenly coat the anti-rust oil applied to the terminals. The brush mechanism 6 includes two liftable brushes 61, and the distance between the two brushes 61 is adapted to the distance between the two terminals on the top surface of the battery.

[0042] The brush mechanism 6 includes a second mounting base 62, on which a brush 61 is mounted. A second drive unit 63 is provided on the mounting plate 3 to drive the second mounting base 62 to rise and fall automatically, enabling the brush 61 to rise and fall automatically. The second mounting base 62 also includes a motor for driving the brush 61 to rotate. The second drive unit 63 can be a motor or a cylinder. To make the rising and falling process of the second mounting base 62 more stable, two vertical guide rods are provided on the mounting plate 3, and the lower ends of the two vertical guide rods are respectively fixed to the second mounting base 62.

[0043] The first positioning mechanism 5 includes a first sensor 51 for detecting the position of the battery and a guide unit 52 for guiding the battery to the bottom of the coating mechanism 4. At the same time, after the first sensor 51 detects the battery, the conveyor belt 2 stops conveying.

[0044] The second positioning mechanism 7 includes a second sensor 71 for detecting the position of the battery. When the battery is transported below the brush mechanism 6, the second sensor 71 detects the battery, and the conveyor belt 2 stops transporting.

[0045] The first sensor 51 and the second sensor 71 can be infrared photoelectric sensors to perform positioning detection of the battery.

[0046] The first mounting base 42 is provided with a first horizontal guide rail 47 arranged along the conveying direction of the conveyor belt 2, and the second mounting base 62 is provided with a second horizontal guide rail 64 arranged along the conveying direction of the conveyor belt 2. Two first mounting bases 48 that can slide along the first horizontal guide rail 47 are provided, and each first mounting base 48 is provided with a coating head 41. Two second mounting bases 65 that can slide along the second horizontal guide rail 64 are provided, and each second mounting base 65 is provided with a brush 61.

[0047] The two first mounting bases 48 and the two second mounting bases 65 can slide along the first horizontal guide rail 47 and the second horizontal guide rail 64 respectively, so as to adjust the distance between the two first mounting bases 48 and the distance between the two second mounting bases 65 respectively, thereby adapting to batteries with different terminal spacing.

[0048] To improve the coating efficiency of battery anti-rust oil, such as Figure 5 As shown, two first horizontal guide rails 47 arranged side by side can be provided on the first mounting base 42, and two first mounting bases 48 are provided on each first horizontal guide rail 47; two second horizontal guide rails 64 arranged side by side are provided on the second mounting base 62, and two second mounting bases 65 are provided on each second horizontal guide rail 64; correspondingly, the first positioning mechanism 5 includes two guide units 52, which are applied to two side by side batteries each time.

[0049] In practice, there are two working modes depending on the coating head.

[0050] Atomization mode (coating head is an atomizing nozzle): The battery is conveyed to the guiding unit via a conveyor belt. The guiding unit guides the battery to the bottom of the coating mechanism. At this point, the first sensor detects the battery, and the conveyor belt stops conveying. The first drive unit drives the first mounting base to descend. The atomizing nozzle mounted on the first mounting base atomizes the oil and sprays it evenly onto the terminal surface of the battery. After spraying is completed, the conveyor belt transports the battery to the next process, and the system resets to wait for the next cycle.

[0051] Brush Mode (Coating Head is a Metered Oil Dispensing Nozzle): The battery is conveyed to the guiding unit via a conveyor belt. The guiding unit guides the battery to the area below the coating mechanism. At this point, the first sensor detects the battery, and the conveyor belt stops. The first drive unit drives the first mounting base to descend, and the metered oil dispensing nozzle mounted on the first mounting base dispenses a metered amount of rust-preventive oil onto the battery terminals. The battery is then conveyed to the area below the brush mechanism. The second sensor detects the battery, and the conveyor belt stops. The second drive unit drives the second mounting base to descend, and the motor drives the brush to rotate, evenly applying the rust-preventive oil to the battery terminals. After completion, the conveyor belt transports the battery to the next process, and the system resets to await the next cycle.
