Description

Technical Field

[0001] The present invention relates to the technical field of battery processing, and more specifically, to an integrated machine for vacuuming steel balls and AB glue dispensing sealing suitable for square steel shell and square aluminum shell batteries and a control method thereof. Background Art

[0002] With the continuous development of square shell battery production technology, there are currently two common ways to seal square shell batteries on the market. One is: plugging sealing nails + welding sealing sheets, and the other is: hitting steel balls + dispensing glue.

[0003] There are different advantages and disadvantages for the two different sealing methods. Among them, the steel ball + glue sealing method is to accurately punch the steel ball into the injection hole of the battery shell after the secondary injection of the battery, and use the elasticity and size of the steel ball to match the injection hole to achieve a tight sealing effect. Then, on the basis of the steel ball sealing, glue is applied around the steel ball or other key parts of the battery shell to further improve the sealing and reliability of the battery.

[0004] The existing battery steel ball injection and glue dispensing equipment can only inject steel balls and dispense glue to one battery at a time, that is, the battery after being injected with steel balls is then dispensed glue through the glue dispensing equipment. Although this method can complete the battery packaging, it is too inefficient and costly. Summary of the invention

[0084] A liquid injection hole packaging device and a control method thereof of the present application are described in detail through the following embodiments.

[0085] Embodiment 1:

[0086] like Figure 1-Figure 2 As shown, in this embodiment, a liquid injection hole packaging device includes: a frame 1, on which a horizontally arranged workbench is provided; a battery positioning mechanism 2, installed on the workbench, for fixing the battery 100 to prevent movement during the steel ball punching and glue dispensing process; a vacuuming mechanism 3, for vacuuming the battery 100 on the battery positioning mechanism 2; a steel ball punching mechanism 4, located above the workbench, for punching steel balls into the liquid injection holes of the battery 100 on the battery positioning mechanism 2 below; a glue dispensing mechanism 5, arranged on the workbench and located on the side of the battery positioning mechanism 2, for quantitatively injecting glue into the liquid injection holes of the battery after the steel ball punching; and a control system, for controlling the operating states of the battery positioning mechanism 2, the steel ball punching mechanism 4 and the glue dispensing mechanism 5, so as to complete the steel ball punching and glue dispensing processes of the battery 100.

[0087] With regard to the existing glue dispensing process of battery packaging, manual operation is generally adopted, which is not only inefficient but also difficult to control the glue output and the glue dispensing position. For this reason, the present embodiment provides a glue dispensing mechanism 5 on the steel ball punching machine, thereby achieving seamless connection between the steel ball punching and glue dispensing processes, and effectively improving the packaging efficiency of the battery.

[0088] Specifically, the battery to be packaged is first placed on the battery positioning mechanism 2, and the battery positioning mechanism 2 fixes the battery. Next, the vacuuming mechanism 3 vacuums the fixed battery, and then the steel ball punching mechanism 4 drives steel balls into the liquid injection hole of the battery. Finally, the glue dispensing mechanism 5 dispenses glue on the liquid injection hole after the steel ball is punched, so as to achieve the sealing of the battery liquid injection hole.

[0089] Among them, it should be noted that by evacuating the battery, on the one hand, the air, moisture and other impurities that may exist inside the battery can be removed; on the other hand, a negative pressure state is formed inside the battery after evacuation. At this time, the steel ball is sealed. Under the action of the pressure difference, the steel ball can be more easily and tightly pressed into the injection hole, thereby achieving a better sealing effect.

[0090] Embodiment 2:

[0091] This embodiment is a further improvement made on the basis of the first embodiment.

[0092] like Figure 1-Figure 3 As shown, in this embodiment, the glue dispensing mechanism 5 includes: a glue dispenser 51, used to inject glue into the glue dispensing area of ​​the battery on the battery positioning mechanism 2; a glue dispenser transfer part 52, used to drive the glue dispenser 51 to move closer to or away from the glue dispensing area of ​​the battery on the battery positioning mechanism 2; and an angle adjustment frame 53, which is arranged on the lower workbench 12 and is used to adjust the angle of the glue dispenser 51.

[0093] Since different types of batteries have different volumes and injection hole positions, an angle adjustment frame 53 is provided to enable the glue dispenser 51 to accurately inject glue into the injection hole, so as to adjust the angle position of the glue dispenser 51 so that it can dock with the injection hole of the battery. In order to avoid interference between the glue dispenser 51 and other mechanisms, a glue dispenser transfer unit 52 is also provided. The glue dispenser transfer unit 52 is a device that can move the glue dispenser 51. When the battery is being glued, the glue dispenser 51 is transferred to the glue dispensing position of the battery by the glue dispenser 51. After the glue dispensing is completed, the glue dispenser 51 is moved to a position away from the battery.

[0094] It should be noted that the glue dispensing quality can be guaranteed by controlling the glue dispensing amount and glue dispensing time of the glue dispenser 51 .

[0095] It should be noted that the dispensing device transfer part 52 is a linear drive device, for example, a linear motor, a cylinder, a hydraulic cylinder, an electric cylinder and the like.

[0096] It should be noted that the angle adjustment frame 53 can rotate 360°, specifically, it includes: a vertically arranged support column 531, a fixed block 532 that can be adjusted up and down is provided on the support column 531, a first glue dispenser 51 rotation axis is provided on the fixed block 532, a transfer block 534 is provided on the first glue dispenser 51 rotation axis, a second glue dispenser 51 rotation axis is provided on the transfer block 534, and a connecting block 536 is provided on the second glue dispenser 51 rotation axis;

[0097] The glue dispenser 51 is mounted on the glue dispenser transfer part 52, and the glue dispenser transfer part 52 is mounted on the connecting block 536;

[0098] The position of the glue dispenser 51 in the vertical direction is adjusted by adjusting the fixing block 532 , and then the tilt angle of the glue dispenser 51 is adjusted by adjusting the transfer block 534 and the connecting block 536 .

[0099] Embodiment three:

[0100] This embodiment is a further improvement made on the basis of the second embodiment.

[0101] In this embodiment, the dispensing mechanism 5 also includes: a visual detection module for real-time monitoring of the dispensing area of ​​the battery on the battery positioning mechanism 2, so that the dispensing device transfer part 52 and the angle adjustment frame 53 can adjust the dispensing position of the dispensing device 51 in real time.

[0102] Visual inspection technology is a technology based on industrial cameras. It captures images or video data of the target object, and then according to the analysis results of the image processing software, the control system will issue corresponding instructions to achieve real-time monitoring and correction of the dispensing area on the battery to ensure the accuracy of the dispensing position.

[0103] Embodiment 4:

[0104] This embodiment is a further improvement made on the basis of any of the above embodiments.

[0105] like Figure 1 , Figure 2 , Figure 4-Figure 6 As shown, in this embodiment, in order to improve the integration of the entire injection hole packaging device, the workbench is divided into an upper workbench 11 and a lower workbench 12 which are arranged up and down, and the upper workbench 11 and the lower workbench 12 are connected by pillars 13 arranged around them.

[0106] The battery positioning mechanism 2 is arranged on the lower workbench 12, and includes: a battery placement box 21 with an upper opening, and a positioning assembly 22 for fixing the battery placed in the battery placement box 21. The battery to be punched with steel balls is placed in the battery placement box 21, and then the battery is fixed in a suitable position by the positioning assembly 22.

[0107] The vacuum mechanism 3 includes: a lifting platform 31, which is arranged at the bottom of the upper workbench 11 and can move up and down along the vertical Z-axis direction. The steel ball hitting mechanism 4 is arranged on the lifting platform 31; and a vacuum box 32, whose lower end is an open structure and is arranged at the bottom of the lifting platform 31. After the vacuum box 32 is docked with the battery placement box 21, the batteries placed in the battery placement box 21 are vacuumed.

[0108] The lifting platform 31 is a platform structure that can rise and fall, and is used to carry the vacuum box 32 and the steel ball hitting mechanism 4, so that the vacuum box 32 and the steel ball hitting mechanism 4 can rise or fall at the same time, thereby realizing the vacuuming and steel ball hitting of the battery.

[0109] Specifically, by driving the lifting platform 31 to move downward, the vacuum box 32 is docked with the battery placement box 21 below. At this time, the vacuum box 32 and the battery placement box 21 are in a closed state. Subsequently, the vacuum box 32 is evacuated through the air holes 321 on the side of the vacuum box 32, and the internal air pressure reaches -0.085~-0.095MPa and then stops. Then, the steel ball hitting mechanism 4 hits the steel ball into the liquid injection hole of the battery below. After the steel ball hitting mechanism 4 completes the action, the vacuum box 32 is de-vacuated so that the lifting platform 31 can be reset, and the vacuum box 32 is separated from the battery placement box 21.

[0110] It should be noted that the positioning component 22 can fix the battery by clamping. Since the battery has a square structure, the two adjacent outer walls of the battery can be pressed against the two adjacent inner walls of the battery placement box 21. The other two adjacent outer walls on the battery can be achieved by two cylinders. A pressure block is set at the end of the piston rod of the two cylinders, and then the battery can be fixed in the battery placement box 21 by driving the cylinder to extend. After the cylinder contracts, the battery can be taken out of the battery placement box 21.

[0111] It should be noted that the lifting platform 31 is connected to the upper workbench 11 through sliding bars vertically arranged on all sides. The lifting platform 31 is located between the upper workbench 11 and the lower workbench 12, and can move up and down through the sliding bars. The lifting platform 31 also has a driving part that drives it to move up and down. The driving part can adopt a linear motor, a cylinder, a hydraulic cylinder or an electric cylinder.

[0112] It should be noted that the air holes 321 on the side of the vacuum box 32 are connected to an external vacuum system through a pipeline, which can evacuate and release the vacuum box 32.

[0113] Embodiment five:

[0114] This embodiment is a further improvement made on the basis of the fourth embodiment.

[0115] like Figure 1 , Figure 2 , Figure 5-Figure 8 As shown, in the present embodiment, the steel ball pressing mechanism 4 includes: a first steel ball pressing needle 41, movably arranged along the vertical Z-axis direction; a first steel ball pressing needle driving assembly 42, arranged on the lifting platform 31, for driving the first steel ball pressing needle 41 to move up and down, so that the first steel ball pressing needle 41 and the steel ball pass through the lifting platform 31 and the vacuum box 32 and are embedded in the liquid injection hole of the battery; and a steel ball feeding assembly 43, for delivering the steel ball to the area where the first steel ball pressing needle 41 moves up and down.

[0116] Since the inner diameter of the battery injection hole is very narrow, a first steel ball pressing needle 41 is provided to drive the steel ball into the battery injection hole. First, the steel ball feeding assembly 43 is used to feed, and then the first steel ball pressing needle driving assembly 42 is started to drive the first steel ball pressing needle 41 to move downward. During the downward movement of the first steel ball pressing needle 41, the steel ball is driven into the battery injection hole.

[0117] Since the sealing of the vacuum box 32 needs to be ensured during the operation of the steel ball hitting mechanism 4, the steel ball feeding assembly 43 is optimized for this purpose. Specifically, the steel ball feeding assembly 43 includes: a mounting frame 431, which is arranged on the lifting platform 31, and the first steel ball pressing needle driving assembly 42 is arranged on the mounting frame 431; a feeding tank 432, which is arranged on the mounting frame 431, and is used to store steel balls and discharge steel balls from its discharge port; a steel ball feeding plate 433, which is slidably arranged on the mounting frame 431 in the horizontal direction, and is provided with a steel ball hole 4331; and a steel ball feeding plate translation part 434, which is used to drive the steel ball feeding plate 433 to move, so that the steel balls discharged from the feeding tank 432 fall into the steel ball hole 4331, or the steel balls in the steel ball hole 4331 are transferred to the bottom of the first steel ball pressing needle 41.

[0118] It should be noted that, in order to allow the steel ball to be smoothly driven into the battery filling hole through the first steel ball pressing needle 41, a feeding hole is provided on the top of the vacuum box 32, and the lifting platform 31 has a through hole coaxial with the feeding hole. The lifting platform 31 is also provided with a guide needle sleeve 44 whose lower end passes through the through hole and the feeding hole, and the upper end of the guide needle sleeve 44 abuts against the bottom of the steel ball feeding plate 433, and the lower end thereof passes downward through the lifting platform 31 and extends into the vacuum box 32, wherein the guide needle sleeve 44 is sealedly connected to the lifting platform 31 and the vacuum box 32.

[0119] When the vacuum box 32 is evacuated, the steel ball feeding plate 433 seals the upper port of the guide needle sleeve 44. When the steel ball is struck, the steel ball feeding plate translation part 434 drives the steel ball feeding plate 433 to move so that the steel ball hole 4331 thereon is located at the discharge port of the loading tank 432. After the steel ball falls into the steel ball hole 4331, the steel ball feeding plate 433 moves again until the steel ball hole 4331 thereon is opposite to the upper port of the guide needle sleeve 44. At this time, the first steel ball pressing needle 41 is also located directly above the steel ball hole 4331 of the steel ball feeding plate 433. Then the first steel ball pressing needle driving assembly 42 is started, causing the first steel ball pressing needle 41 to move downward, and the steel ball is struck into the guide needle sleeve 44, and then discharged from the lower port of the guide needle sleeve 44 and enters the injection hole of the battery. After that, the first steel ball pressing needle 41 continues to move downward to strike the steel ball into a certain depth in the injection hole of the battery.

[0120] It should be noted that the lower end of the guide needle sleeve 44 needs to be docked with the injection hole on the battery to prevent the steel ball from failing to smoothly enter the injection hole of the battery. In other words, if the guide needle sleeve 44 needs to be docked with the injection hole of the battery for batteries of different heights, the lower end of the guide needle sleeve 44 needs to be moved downward, so the guide needle sleeve 44 can be set as a telescopic sleeve structure to adapt to batteries of different models.

[0121] Embodiment six:

[0122] This embodiment is a further improvement made on the basis of the fifth embodiment.

[0123] like Figure 1 , Figure 2 As shown, in this embodiment, a window 111 is opened on the upper workbench 11, and a mounting frame 431 is movably arranged on the lifting platform 31 up and down; the steel ball feeding assembly 43 also includes: a feeding lifting part 435, which is used to drive the mounting frame 431 to move up and down so that the feeding tank 432 extends upward from the window 111.

[0124] In order to facilitate the staff to add steel balls into the upper material tank 432, a window 111 is opened on the upper workbench 11, and then the mounting frame 431 is driven upward by the loading drive unit so that the loading tank 432 extends out from the window 111. At this time, the staff can stand on the side of the frame 1 and add steel balls into the upper material tank 432.

[0125] Embodiment seven:

[0126] This embodiment is a further improvement made on the basis of the fourth, fifth and sixth embodiments.

[0127] like Figure 1 , Figure 2 , Figure 4 As shown, in this embodiment, the battery placement box 21 is movably arranged on the lower workbench 12, and the steel ball mechanism 4 is used to pre-punch the steel ball into the battery injection hole;

[0128] The liquid injection hole packaging device further includes: a secondary steel ball punching mechanism 6, which is used to punch the steel ball in the battery liquid injection hole into the final preset position, and a battery placement box translation part 7, which is used to drive the battery placement box 21 to move, so as to adjust the position of the battery placement box 21 on the lower workbench 12;

[0129] The secondary steel ball pressing mechanism 6 includes: a second steel ball pressing needle 61, which is movably arranged along the vertical Z-axis direction; a sensor 62, which is used to detect the height of the downward position of the second steel ball pressing needle 61; and a second steel ball pressing needle driving assembly 62, which is arranged on the upper workbench 11 and is used to drive the second steel ball pressing needle 61 to move up and down, so as to press the steel ball in the battery filling hole on the battery positioning mechanism 2 below into a preset position;

[0130] The second pressing steel ball needle driving assembly 62 is controlled to drive the second pressing steel ball needle 61 to move downward according to the signal detected by the sensor 62 .

[0131] When the steel ball hitting mechanism 4 is hitting the battery with steel balls, the battery is sealed by the battery placement box 21 and the vacuum phase, which makes it impossible for the steel ball hitting mechanism 4 to adjust the depth of the steel ball hitting in real time, and it is easy for the steel balls to be hit too deeply or too shallowly. For this reason, in this embodiment, the steel ball hitting mechanism 4 is configured to pre-hit the steel balls, and then a secondary steel ball hitting mechanism 6 is provided for hitting the steel balls on the battery for the second time. Under the action of the secondary steel ball hitting mechanism 6, the depth of the steel balls on the battery can be accurately controlled.

[0132] Specifically, after the steel ball pressing mechanism 4 pre-punches the battery with steel balls, the battery is moved to the bottom of the second steel ball pressing needle 61, and then the second steel ball pressing needle 61 is driven downward by the second steel ball pressing needle driving assembly 62. Then, under the action of the side sensor 62, the downward movement of the second steel ball pressing needle 61 is controlled, thereby realizing the precise steel ball pressing process for the battery.

[0133] It should be noted that pre-driving steel balls refers to driving the steel balls into the battery to a certain depth for the first time, and secondary driving steel balls refers to driving the steel balls into the battery a second time so that the steel balls reach the set depth.

[0134] It should be noted that the sensor 62 is a multi-point laser sensor 62, which is used to accurately detect the downward movement of the second steel ball needle 61. After the downward movement of the second steel ball needle reaches a preset value, the second steel ball needle driving assembly 62 is controlled to stop moving or move in the opposite direction.

[0135] In this embodiment, the battery positioning mechanism 2 is optimized to be provided with a pressure sensing unit for detecting the pressure exerted on the battery when the steel ball striking mechanism 4 performs pre-steel ball striking on the battery;

[0136] When the pressure detected by the pressure sensing unit is less than a preset value, after the battery is pre-punched with steel balls, the control system controls the secondary steel ball punching mechanism 6 to perform secondary steel ball punching on the battery;

[0137] After the pressure detected by the pressure sensing unit reaches a preset value, after the battery is pre-punched with steel balls, the control system controls the secondary steel ball punching mechanism 6 to stop the secondary steel ball punching of the battery.

[0138] The pressure sensor is used to detect the pressure exerted on the battery when the steel ball is driven into the battery. The detection of this pressure value is mainly used to control the depth of the steel ball when the battery is pre-driven. The pressure exerted on the battery when the steel ball is driven into the battery is different. Therefore, the pressure exerted on the battery when the steel ball is driven into the battery needs to be accurately controlled. Since the equipment has certain fluctuations during operation, the pressure acting on the battery may occasionally be too small. Therefore, a pressure sensing unit is set to perform real-time detection. When the pressure exerted on the battery reaches the preset value, it means that the steel ball driving mechanism has accurately driven the steel ball into the battery filling hole. At this time, there is no need to drive the steel ball into the battery for the second time. If the detected pressure is too small, it means that the steel ball driving depth in the battery filling hole is too small. At this time, the secondary steel ball driving mechanism is used to drive the steel ball into the battery for the second time, thereby achieving accurate battery packaging with high efficiency.

[0139] Embodiment eight:

[0140] This embodiment is a further improvement made on the basis of the seventh embodiment.

[0142] Since the battery steel ball punching and glue dispensing process has many steps, in order to improve the efficiency of the entire integrated machine, two groups of battery positioning mechanisms 2 are set, and then two groups of secondary steel ball punching mechanisms 6 are also set, so as to achieve seamless connection of battery steel ball punching, glue dispensing and loading and unloading.

[0143] Embodiment nine:

[0144] This embodiment provides a control method for a liquid injection hole packaging device, and the specific steps of the control method are as follows:

[0146] S2, control the lifting platform 31 to move downward, so that the vacuum box 32 docks with the battery placement box 21 below it, and then vacuumizes the vacuum box 32;

[0148] If the pressure sensing unit detects that the pressure on the battery reaches a preset value, step S3 is executed; if the pressure sensing unit detects that the pressure on the battery is less than the preset value, step S4 is executed;

[0149] During step S2, the batteries to be packaged need to be placed in the battery placement box 21 located below another secondary steel ball punching mechanism 6;

[0151] S4, control the sliding plate 121 to move, so that the battery after pre-punching with steel balls is reset to the loading position, and the battery without steel balls is transferred to the bottom of the vacuum box 32; then the secondary steel ball punching mechanism 6 performs secondary steel ball punching on the battery after pre-punching with steel balls, so that the steel balls reach the preset position;

[0152] S5, in the process of performing secondary steel ball beating on the battery in step S4,

[0153] Control the lifting platform 31 to move downward, so that the vacuum box 32 docks with the battery placement box 21 below it, and then vacuumize the vacuum box 32;

[0154] The steel ball striking mechanism 4 is controlled to pre-strike the steel ball into the injection hole of the battery in the battery placement box 21, and then the vacuum box 32 is evacuated, and the lifting platform 31 is controlled to move upward and reset; wherein, if the pressure sensing unit detects that the pressure on the battery reaches a preset value, step S6 is executed; if the pressure sensing unit detects that the pressure on the battery is less than the preset value, step S7 is executed;

[0155] S6, the glue dispensing mechanism 5 dispenses glue to the battery after the second steel ball punching under the vacuum box 32; then the sliding plate 121 is controlled to move, so that the battery after the glue dispensing is reset to the loading position, and another battery after the second steel ball punching is moved to the bottom of the vacuum box 32; then the battery after the glue dispensing is removed, and the battery to be packaged is placed or the placement is stopped, and at the same time, the glue dispensing mechanism 5 dispenses glue to another battery after the second steel ball punching;

[0156] S7, control the sliding plate 121 to move, so that the newly loaded battery is transferred to the bottom of the vacuum box 32, the battery after glue application is reset to the loading position, and the battery is removed, and then return to step S2 or end.

[0157] By adopting the above control method to realize the steel ball punching and glue dispensing of the battery, not only is the efficiency high, but the depth of the steel ball punching and the amount of glue dispensing can be accurately controlled, which effectively improves the sealing effect of the battery.
