Description

Technical Field

[0001] This utility model relates to the field of battery production equipment, and in particular to a battery terminal cleaning device. Background Technology

[0002] In the manufacturing process of lead-acid batteries, the battery terminals need to be welded first, and then red and blue adhesives are injected into the positive and negative terminals respectively for sealing. However, residues from the welding process, as well as lead shavings and oxides on the terminals, may affect the sealing performance of the adhesive. Currently, the terminals are generally cleaned manually using cloths and blow guns, which is time-consuming and labor-intensive.

[0003] CN202322868331 discloses an automatic battery terminal cleaning device, including a bed, a conveyor belt, and a blowing assembly. "C"-shaped baffles are fixed on both sides along the length of the bed, and the conveyor belt is installed between the two "C"-shaped baffles. A blowing assembly is fixed on the upper part of the two "C"-shaped baffles. The blowing assembly includes a fixed frame A, a fixed frame B, an air pipe, and brush bristles. Fixed frames A and B have the same structure, both being "n"-shaped, and each has two through holes on its top surface. An air pipe is inserted into the two through holes of fixed frame A. One end of the air pipe has a nozzle corresponding to the position of the battery terminal on the conveyor belt, and the other end is connected to an air source. A solenoid valve is installed on the air pipe and fixed to the outer end face of either "C"-shaped baffle. A support plate is fixed on the upper part of fixed frame B, and motors are fixed at intervals on the upper part of the support plate. The output ends of two motors are connected to brush bristles through connectors, and the brush bristles are arranged corresponding to the positions of the battery terminals on the conveyor belt. Although the cleaning device uses brushes and air nozzles to clean the poles, the brushes cannot move up and down, so they cannot clean the grooves where the poles are located very well. Secondly, the air nozzles blow vertically downwards, so some waste may be blown to the bottom or side wall and remain at the pole position.

[0004] The technical problem that this invention aims to solve is: how to improve the cleaning effect of battery terminals. Utility Model Content

[0005] The main purpose of this utility model is to provide a battery terminal cleaning device. By setting a cleaning unit to clean the waste on the terminal first, most of the waste on the terminal is removed from the terminal. Then, a driving unit and an air blowing unit are set. The driving unit drives the air blowing unit to swing left and right and blow air onto the terminal, so that the terminal and the waste in the groove where the terminal is located are removed from the battery, thereby improving the cleaning effect.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A battery terminal cleaning device includes a frame and a conveying unit, a cleaning unit, an air blowing unit, and a driving unit mounted on the frame; the cleaning unit and the air blowing unit are sequentially connected to the frame along the battery conveying direction and are located above the conveying unit; the driving unit is connected to the frame.

[0008] The drive unit is used to drive the air blowing unit to swing left and right above the battery terminal; the air blowing unit is used to remove residual waste from the battery terminal.

[0009] Preferably, the air blowing unit includes a rotating plate and an air jet head; the rotating plate is rotatably connected to the frame; the air jet head is connected to the rotating plate; the position of the air jet head corresponds to the position of the pole post.

[0010] Preferably, the drive unit is a stepper motor or a servo motor; the power output end of the drive unit is connected to the rotating plate.

[0011] Preferably, the driving unit comprises a first motor, a cam, and a spring; a connecting plate is provided on the side of the rotating plate near the driving unit; the motor is connected to the frame; the cam is connected to the power output end of the first motor; the two ends of the spring are respectively connected to the connecting plate and the frame; the spring is used to keep the connecting plate in contact with the contour of the cam; the first motor is used to drive the cam to rotate so that the cam drives the connecting plate to swing left and right.

[0012] Preferably, the cleaning unit includes a lifting plate, a brush, a first drive module for moving the lifting plate up and down, and a second drive module for rotating the brush; the first drive module is connected to the frame; the lifting plate is slidably connected to the frame; the second drive module is connected to the lifting plate; and the brush is rotatably connected to the lifting plate.

[0013] Preferably, the first drive module includes a second motor and a lead screw; both ends of the lead screw are rotatably connected to the frame; one end of the lifting plate is slidably connected to the lead screw; the second motor is connected to the frame; the second motor is used to drive the lead screw to rotate.

[0014] Preferably, the frame is provided with a guide shaft; the other end of the lifting plate is slidably connected to the guide shaft.

[0015] Preferably, the frame is equipped with a sensor; the sensor is used to detect whether the battery terminals have reached below the cleaning unit.

[0016] Compared with existing technologies, this solution has the following advantages:

[0017] The cleaning device in this case first cleans the waste on the electrode post by setting up a cleaning unit, so that most of the waste on the electrode post is removed from the electrode post; then a drive unit and an air blowing unit are set up. The drive unit drives the air blowing unit to swing left and right and blow air towards the electrode post instead of blowing air vertically downward. This allows the waste remaining on the electrode post and the waste in the groove where the electrode post is located to be completely blown away, avoiding the waste from being attached to the bottom and side walls of the groove where the electrode post is located due to blowing air vertically downward. This improves the cleaning effect and ensures the sealing of subsequent glue injection.

[0018] Secondly, the cleaning unit is equipped with a lifting module, which drives the brush to move up and down, thereby cleaning the waste on the pole and the waste inside the groove where the pole is located, improving the cleaning effect. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Example 1

[0026] refer to Figure 1-3A battery terminal cleaning device includes a frame 1 and a conveying unit 2, a cleaning unit 3, an air blowing unit 4, and a driving unit 5 disposed on the frame 1; the cleaning unit 3 and the air blowing unit 4 are sequentially connected to the frame 1 along the battery conveying direction and are located above the conveying unit 2; the driving unit 5 is connected to the frame 1.

[0027] The drive unit 5 is used to drive the air blowing unit 4 to swing left and right above the battery terminal; the air blowing unit 4 is used to remove residual waste from the battery terminal.

[0028] In this embodiment, the lead-acid battery casing has two grooves, and two terminals are placed in the grooves respectively. The terminals are then welded into the grooves. This cleaning device is used to clean the welded terminals and grooves to meet the requirements of the subsequent glue injection process.

[0029] The conveying unit 2 is existing technology, specifically a conveyor belt.

[0030] The specific process of this cleaning device is as follows: the conveying unit 2 conveys the battery with the welded terminals to the bottom of the cleaning unit 3, and the cleaning unit 3 cleans the terminals and the grooves where the terminals are located; after cleaning, the conveying unit 2 conveys the battery to the bottom of the blowing unit 4, and starts the blowing unit 4 and the drive unit 5. The drive unit 5 drives the blowing unit 4 to swing left and right to blow air onto the terminals, blowing away the residual waste in the terminals and the grooves where the terminals are located; after blowing is completed, the conveying unit 2 conveys the battery to the next process.

[0031] Preferably, the air blowing unit 4 includes a rotating plate 41 and an air jet head 42; the rotating plate 41 is rotatably connected to the frame 1; the air jet head 42 is connected to the rotating plate 41; the position of the air jet head 42 corresponds to the position of the pole post.

[0032] In this embodiment, an air pipe is connected to the jet head 42, and an air pump is connected to the end of the air pipe. The air pump supplies gas to the jet head 42 through the air pipe. The drive unit 5 drives the rotating plate 41 to rotate left and right on the frame 1 by a certain angle, thereby causing the jet head 42 to swing left and right. The rotation angle can be set according to actual needs.

[0033] Preferably, the drive unit 5 comprises a first motor 51, a cam 52, and a spring 53; the rotating plate 41 has a connecting plate 411 on the side near the drive unit 5; the motor is connected to the frame 1; the cam 52 is connected to the power output end of the first motor 51; the two ends of the spring 53 are respectively connected to the connecting plate 411 and the frame 1; the spring 53 is used to keep the connecting plate 411 in contact with the contour of the cam 52; the first motor 51 is used to drive the cam 52 to rotate so that the cam 52 drives the connecting plate 411 to swing left and right.

[0034] In this embodiment, the drive unit 5 can also be selected to use a cam 52 to drive the rotating plate 41 to rotate left and right, thereby causing the jet head 42 to swing left and right.

[0035] One end of the spring 53 is connected to the connecting plate 411, and the other end is connected to the frame 1. Through the elastic force of the spring 53, the side of the connecting plate 411 is kept in contact with the side profile of the cam 52. When the first motor 51 drives the cam 52 to rotate, since the side profile of the cam 52 has a highest point and a lowest point, when the first motor 51 drives the cam 52 to rotate, the highest point and the lowest point of the side profile of the cam 52 cycle through the connecting plate 411, so that the connecting plate 411 swings left and right according to the profile of the cam 52. The spring 53 can ensure that the connecting plate 411 is always in contact with the side of the cam 52 when the cam 52 is rotating.

[0036] Preferably, the cleaning unit 3 includes a lifting plate 31, a brush 32, a first drive module 33 for moving the lifting plate 31 up and down, and a second drive module 34 for rotating the brush 32; the first drive module 33 is connected to the frame 1; the lifting plate 31 is slidably connected to the frame 1; the second drive module 34 is connected to the lifting plate 31; and the brush 32 is rotatably connected to the lifting plate 31.

[0037] In this embodiment, the specific working process of the cleaning unit 3 is as follows: when the battery terminal reaches below the brush 32, the first drive module 33 drives the lifting plate 31 to descend, thereby driving the brush 32 to descend to the terminal. At this time, the bristles of the brush 32 contact the terminal and the groove where the terminal is located. The second drive module 34 drives the brush 32 to rotate, thereby cleaning the waste in the terminal and the groove where the terminal is located. After cleaning, the first drive module 33 drives the brush 32 to rise to the initial position to avoid the brush 32 blocking the battery and changing the position of the battery on the conveying unit 2, thereby ensuring that the blowing unit 4 can blow air on the terminal.

[0038] Preferably, the first drive module 33 includes a second motor 331 and a lead screw 332; both ends of the lead screw 332 are rotatably connected to the frame 1; one end of the lifting plate 31 is slidably connected to the lead screw 332; the second motor 331 is connected to the frame 1; the second motor 331 is used to drive the lead screw 332 to rotate.

[0039] In this embodiment, the second motor 331 drives the lead screw 332 to rotate, and the lead screw 332 drives the lifting plate 31 to move up and down on the frame 1 through the ball nut.

[0040] The second drive module 34 is a motor.

[0041] Preferably, the frame 1 is provided with a guide shaft 11; the other end of the lifting plate 31 is slidably connected to the guide shaft 11.

[0042] In this embodiment, a guide shaft 11 is provided on the frame 1. The guide shaft 11 and the lead screw 332 are symmetrically arranged on both sides of the frame 1, and the guide shaft 11 is slidably connected to the other end of the lifting plate 31. By setting the guide shaft 11, the smoothness of the lifting plate 31 during the up and down movement is improved.

[0043] Preferably, the frame 1 is provided with a sensor 12; the sensor 12 is used to detect whether the battery terminals have reached below the cleaning unit 3.

[0044] In this embodiment, the sensor 12 is an infrared sensor 12. By setting the sensor 12 in a suitable position, when the battery is detected by the sensor 12, the position of the battery terminal is just below the cleaning unit 3.

[0045] This cleaning device is also equipped with a control unit, which is a PLC or a microcontroller. The control unit is communicatively connected to the conveying unit 2, the cleaning unit 3, the air blowing unit 4, and the sensor 12.

[0046] When sensor 12 detects the battery, the conveying unit 2 stops conveying the battery forward, the cleaning unit 3 cleans the terminal post, and after cleaning, the conveying unit 2 continues to convey the battery forward until it is directly below the blowing unit 4. The blowing unit 4 blows air onto the terminal post, and after blowing, the conveying unit 2 conveys the battery to the next process.

[0047] Since the distance between the cleaning unit 3 and the blowing unit 4 is constant, only one sensor 12 needs to be set up to detect whether a battery has reached the bottom of the cleaning unit 3. Then, the control unit records the distance between the cleaning unit 3 and the blowing unit 4 and drives the conveying unit 2 to convey the battery from the bottom of the cleaning unit 3 to the bottom of the blowing unit 4.

[0049] refer to Figure 4 This embodiment is basically the same as embodiment 1, except that: the driving unit 5 is a stepper motor or a servo motor; the power output end of the driving unit 5 is connected to the rotating plate 41.

[0050] In this embodiment, the drive unit 5 is a stepper motor. The stepper motor needs to be used with a driver, and the power output end of the stepper motor is connected to the end of the rotating plate 41. By controlling the driver, the stepper motor can be controlled to rotate left and right by a certain angle, thereby realizing the left and right swing of the jet head 42.
