Description

Technical Field

[0001] The invention relates to the technical field of terminal protection, in particular to an automatic point-adding device for terminal protection oil. Background Art

[0002] In the existing battery production process, after the terminal welding is completed, in order to prevent the positive and negative terminals of the battery from being exposed to the air for a long time and coming into contact with water molecules in the air, causing corrosion and oxidation on the surface of the terminals, it is often necessary to apply protective oil to the surfaces of the positive and negative terminals. Terminal protective oil is a special oily antioxidant that can prevent terminal oxidation.

[0003] In the prior art, the Chinese invention with publication number CN219580924U discloses a terminal coating device for multiple types of lead-acid batteries, including a support, a bracket, a brush head mechanism and an oil tank; the support stands on one side of the battery conveyor belt; the bracket is located directly above the battery conveyor belt and can be vertically raised and lowered with the cylinder, and the cylinder is installed on the support through a support block; the brush head mechanism consists of two, and the relative positions are adjustable and mounted side by side on the bracket, each brush head mechanism includes a connecting block, a through step hole is opened in the middle of the connecting block, the step hole includes a small hole at the upper end and a large hole connected to the lower end of the small hole, and the inner wall of the large hole is provided with a cylindrical foam with an open lower end and a closed upper end for coating the battery terminals; a circular tube extends vertically upward from the upper end of the connecting block, and the inner hole of the circular tube is connected to the small hole; the two oil outlets at the lower end of the oil tank are respectively connected to the circular tubes on the upper part of the corresponding connecting block through hoses. It can be used to apply protective oil to the terminals of various types of lead-acid batteries. One set of equipment can match different types of batteries, has a wide range of adaptability, and can reduce production costs.

[0004] In the above technical solution, the position of the battery is detected by a sensor, and the protective oil applied to the battery electronics by the cylindrical foam is used to position the battery. However, the sensor can only detect the presence of a battery and cannot detect the neatness of the battery placement. When the battery is transported at an angle, the sensor also detects the battery, but the cylindrical foam moves downward and cannot be accurately put on the electronics, resulting in the failure of the protective oil application to the terminal, requiring rework, which reduces production efficiency.

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0030] The present invention provides Figures 1 to 5 The terminal protective oil automatic dosing device shown includes:

[0031] A conveying assembly 2 for continuously conveying batteries, the conveying assembly 2 being installed in the mounting base frame 1;

[0032] A protective oil container tank 3 is provided above the conveying component 2, and an oil guide rod 4 is provided in the inner cavity of the protective oil container tank 3. The lower section of the oil guide rod 4 is a hollow tubular structure connected to the inner cavity of the protective oil container tank 3. The bottom of the oil guide rod 4 passes through the bottom of the protective oil container tank 3 and is fixed with an oil brush head 5. A protective tube is fixed to the bottom of the protective oil container tank 3 and is sleeved on the outside of the oil guide rod 4. A sealing ring is provided between the protective tube and the oil guide tube to prevent the protective oil from flowing out along the gap between the protective tube and the oil guide rod 4. The upper section of the oil guide rod 4 passes through the top of the protective oil container tank 3. A support plate 6 is provided on the top of the protective oil container tank 3. The oil guide rod 4 is rotatably connected to the support plate 6 through a bearing. A rotating component 7 for rotating the oil guide rod 4 is provided on the top of the support plate 6.

[0033] A support frame is fixed to the outside of the protective oil container tank 3, and support rods 8 are fixed around the bottom of the support frame. A light-point component 9 for moving the support rods 8 up and down is provided at the bottom of the mounting base frame 1;

[0034] A lifting assembly 10 is further provided on the outside of the mounting base frame 1. A connecting rod 11 is installed on the top of the lifting assembly 10. A plurality of limiting plates 12 for limiting the position of the battery are fixed in sequence on the opposite side of the connecting rod 11. A clamping assembly 13 for calibrating the position of the battery is also provided on the limiting plate 12.

[0035] The batteries are continuously conveyed by the conveying component 2 and pass under the protective oil container tank 3 in turn. Then the lifting component 10 drives the limit plate 12 to move down through the connecting rod 11 to stop the battery. Then the clamping component 13 calibrates the position of the battery to keep the battery neat and located under the two sets of oil guide rods 4. This can ensure that the oil brush head 5 is aligned with the terminals on the battery. Then, driven by the light tapping component 9, the oil brush head 5 moves down to contact the terminals, and at the same time, the protective oil in the protective oil container tank 3 is drained. The rotating component 7 is used to rotate the oil guide rod 4, and the protective oil is evenly applied using the oil brush head 5. This not only allows the terminals to be brushed accurately, but also ensures the processing quality.

[0036] It is worth noting that: a plurality of sensors are installed on the inner side of the mounting base frame 1 for detecting the position of the battery.

[0037] Among them, Figure 3 As shown:

[0038] The conveying assembly 2 includes support rollers 21 rotatably mounted at both ends of the inner cavity of the mounting base frame 1. A conveying belt 22 is sleeved on the outer side of the support rollers 21. A motor 23 is fixed to the outer side of the mounting base frame 1. The output shaft of the motor 23 is fixedly connected to one end of a group of support rollers 21. The motor 23 drives a group of support rollers 21 to rotate, and then cooperates with another group of support rollers 21 to tension and drive the conveying belt 22, so that the conveying belt 22 rotates and continuously conveys the batteries, thereby realizing automatic loading of the batteries.

[0039] Further, such as Figure 4 As shown:

[0040] The rotating assembly 7 includes a fixed frame 71 fixed to one side of the top of the support plate 6, and a rack plate 72 is slidably provided on the inner side of the fixed frame 71. A first electric push rod 73 is fixed to one end of the fixed frame 71. The piston rod of the first electric push rod 73 passes through the inner side of the fixed frame 71 and is fixedly connected to one end of the rack plate 72. A rotating gear 74 is fixed to the top of the oil guide rod 4, and the rotating gear 74 is engaged with the side of the rack plate 72 with teeth. The rack plate 72 is driven to move by the first electric push rod 73, and the rotating gear 74 is used to rotate the oil guide rod 4 synchronously, so that the oil guide rod 4 drives the oil brush head 5 to rotate, and the oil brush head 5 is used to evenly apply the protective oil to prevent the brush from not being able to apply it evenly.

[0041] Preferably, Figure 2 As shown:

[0042] The light-tap component 9 includes a support frame 91 fixed on both sides of the bottom of the mounting base frame 1, and a second electric push rod 92 is fixed to the bottom of the support frame 91. The piston rod of the second electric push rod 92 passes through the interior of the support frame 91 and is fixed with a connecting plate 93. The support rod 8 is fixed on the outside of the connecting plate 93. The connecting plate 93 is driven up and down by the second electric push rod 92, and then the connecting plate 93 adjusts the up and down movement of the four groups of support rods 8 to realize the light tapping of the terminal by the oil-dotting brush head 5, which can not only release the protective oil, but also let the protective oil drip along the oil guide rod 4 onto the oil-dotting brush head 5, transferring the protective oil to the terminal.

[0043] It is worth noting that if Figure 3 As shown:

[0044] The lifting assembly 10 includes a support seat 101 fixed to the outside of the mounting base frame 1, and a third electric push rod 102 is fixed to the bottom of the support seat 101. The piston rod of the third electric push rod 102 passes through the support seat 101 and is fixedly connected to the bottom of the connecting rod 11. Through the setting of the third electric push rod 102, it is convenient to drive the connecting rod 11 to move up and down to adjust the height of the limit plate 12. When the limit plate 12 moves up, it can ensure the normal loading and unloading of the battery. When the limit plate 12 moves down, the battery can be stopped.

[0045] In a further preferred embodiment, Figure 3 As shown:

[0046] The clamping assembly 13 includes two groups of fixed plates 131 fixed on the same side of the limit plate 12. A fourth electric push rod 132 is fixed to the outer side of the fixed plate 131. The piston rod of the fourth electric push rod 132 passes through the fixed plate 131 and is fixed to a movable plate 133. The movable plate 133 can be moved by the fourth electric push rod 132. The two groups of movable plates 133 moving toward each other are used to clamp the battery and calibrate the position to ensure that the battery is located directly below the oil-pointing brush head 5.

[0047] In addition, if Figure 4-5 As shown:

[0048] Two sets of limit frames 14 are fixed on the top of the protective oil container tank 3. The limit frames 14 are located on the outside of the support plate 6. A support spring 15 is fixed to the top of the inner cavity of the limit frame 14. The bottom of the support spring 15 is fixed to the top of the support plate 6. Through the cooperation of the limit frame 14 and the support spring 15, it is convenient to use the support spring 15 to limit the support plate 6, ensuring that the support plate 6 always has a tendency to move downward, avoiding the oil guide rod 4 from continuously transporting the protective oil downward.

[0049] In this embodiment, if Figure 5 As shown:

[0050] The support plate 6 is provided with a plurality of through holes, and a limiting rod 16 is slidingly provided in the inner cavity of the through hole. The bottom of the limiting rod 16 is fixed to the top of the protective oil container tank 3, and the top of the limiting rod 16 is fixed to the top of the inner cavity of the limiting frame 14. The setting of the limiting rod 16 facilitates the limiting of the support plate 6 to prevent the support plate 6 from shaking and causing the oil guide rod 4 to bend.

[0051] In addition, if Figure 5 As shown:

[0052] A limiting groove 17 is provided on the inner side wall of the fixed frame 71, and the rack plate 72 is located in the limiting groove 17. The limiting groove 17 is provided to accommodate and limit the rack plate 72 to ensure that the rack plate 72 does not shake, resulting in the separation of the rotating gear 74 and the rack plate 72.

[0053] In this embodiment, if Figure 3 As shown:

[0054] The inner cavity of the mounting base frame 1 is fixed with multiple groups of supporting base plates 18, which are located directly below the two groups of oil-point brush heads 5, and the supporting base plates 18 are located on the inner side of the conveyor belt 22. The setting of the supporting base plates 18 facilitates the support of the battery, and prevents the conveyor belt 22 from being squeezed, deformed and sunken by the battery, causing the oil-point brush head 5 to move downward and be unable to contact the terminals on the battery.

[0055] During specific use, the motor 23 is started, and the motor 23 drives the support roller 21 to rotate, driving the conveyor belt 22, and the conveyor belt 22 is used to transfer and convey the batteries. When all sensors detect the incoming battery, the third electric push rod 102 drives the connecting rod 11 to move downward, and the connecting rod 11 drives the limit plate 12 to stop the battery. At this time, the conveyor belt 22 continues to rotate, so that multiple groups of batteries are fitted with the limit plate 12, and then the fourth electric push rod 132 drives the movable plate 133 to contact the battery again, and adjust the battery to the center of the conveyor belt 22 and below the oil guide rod 4, align the oil brush head 5 with the terminal on the battery, and then the second electric push rod 92 drives the connecting plate 93 to move downward, and the connecting plate 93 drives the support rod 8 and the support frame move downward, and at the same time, the protective oil container tank 3 moves downward. At this time, the oil guide rod 4 connected to the protective oil container tank 3 moves downward and contacts the terminal through the oil brush head 5. After the oil brush head 5 contacts the terminal, the protective oil container tank 3 continues to move downward. At this time, the oil guide rod 4 moves upward in the protective oil container tank 3 and is connected with the protective oil container tank 3. The internal protective oil flows out along the oil guide rod 4 to the oil brush head 5 and is smeared on the terminal. Then the first electric push rod 73 drives the rack plate 72 to rotate, and the rack plate 72 uses the rotating gear 74 to drive the oil guide rod 4 and the oil brush head 5 to rotate, and evenly smear the protective oil on the battery terminal. After the oil is completed, the limit plate 12 moves upward, and the battery is transported away by the conveyor belt 22. Then the next batch of batteries are transported for recycling processing.

[0056] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
