Description

Technical Field

[0001] The utility model relates to the technical field of battery liquid injection machines, in particular to a linear battery liquid injection machine for improving production efficiency. Background Art

[0002] Battery liquid injection machines are usually divided into two types: disk-type battery liquid injection machines and linear battery liquid injection machines.

[0003] A linear battery liquid injection machine disclosed in CN 109860504 A has a feeding area, an automatic liquid injection assembly, a static device, an automatic sealing assembly, and a discharging area arranged on the machine table in sequence according to the process sequence; in the feeding area, a feeding area and a manual feeding area are arranged from right to left in sequence according to the process sequence. The feeding area is provided with a feeding bin, and a belt conveying device is arranged in the feeding bin. Manual feeding is required, and workers have to place the battery cores one by one.

[0004] In addition, a fast linear liquid injection machine disclosed in CN 117352968 A includes a feeding device, a liquid injection device, a static device, and a discharging device arranged in sequence along a first direction. The feeding device is used to feed the batteries flowing in from the upstream process to the fixture, the liquid injection device is used to inject electrolyte into the batteries, the static device is used to static the batteries after liquid injection to ensure that the electrolyte completely penetrates into the batteries, and the discharging device is used to discharge the batteries and the fixtures. When working, the batteries are fed to the fixture through the feeding device, injected through the liquid injection device, and after being static through the static device, the fixture loaded with the batteries is transferred to the cup discharging station. Subsequently, the cup discharging assembly separates the cup from the pallet, the pallet continues to move to the battery discharging station, and the battery discharging assembly takes out the batteries on the pallet for discharging. At the same time, the cup discharging assembly vertically descends the taken-out cup to the cleaning assembly arranged at the cup discharging station, and the cup is cleaned with cleaning liquid. After the cleaning is completed and the battery discharging is completed, the cup discharging assembly places the cup on the pallet again, and the whole set of fixtures is returned to the feeding device through the fixture return mechanism. Its design concept is also to place and transfer the battery cores one by one, which is not conducive to improving the processing efficiency of the battery cores. Moreover, the designs of each device are complex, the sizes are large, and the equipment manufacturing cost is high. For battery core production and processing manufacturers, the equipment replacement and purchase costs and the storage and management costs in the workshop are all factors that need to be considered, resulting in difficult promotion and application of the equipment.

[0041] A linear battery filling machine for improving production efficiency, comprising a frame 10. Along the left-right direction, a stack lifting and feeding device 20, a filling device 30, a standing device 40, a sealing device 50 and a stack lifting and discharging device 60 are sequentially arranged side by side on the frame 10. Generally, a trolley pushing position 70 is also provided, that is: a trolley pushing position 70 is provided on the feeding side of the stack lifting and feeding device 20, and a trolley pushing position 70 is provided on the discharging side of the stack lifting and discharging device 60. The trolley entrance of the trolley pushing position 70 is arranged on the right side or the front side of the trolley pushing position. In this embodiment, a trolley pushing position 70 is provided on the left side of the stack lifting and feeding device 20. The trolley entrance of the trolley pushing position 70 is arranged on the left side or the front side of the trolley pushing position. The right side of the trolley pushing position 70 is communicable with the left side of the stack lifting and feeding device 20. A first conveyor belt assembly 71 is provided at the bottom of the trolley pushing position 70. After the trolley is pushed in, the pallet baskets of several stacks on the trolley are located above the first conveyor belt assembly 71. And a second conveyor belt assembly 21 is provided at the bottom of the stack lifting and feeding device 20. The first conveyor belt assembly 71 and the second conveyor belt assembly 21 are arranged side by side left and right, and can transfer the pallet baskets of several stacks on the trolley from the trolley to the stack lifting and feeding device 20. The stack lifting and feeding device 20 lifts the pallet baskets of several stacks upward so that the uppermost pallet basket is in a state convenient for feeding. The stack lifting and discharging device 60 has the same structure as the stack lifting and feeding device 2.

[0042] A synchronous conveying device 90 is further provided on the rack 10; the synchronous conveying device 90 includes two synchronous beams 901 arranged at a front-back interval and extending left and right. Between the two synchronous beams 901, there are successively arranged a loading station 1, a liquid injection station 2, a standing station 3, a sealing station 4 and a discharging station 5 from left to right. Four manipulators 91 are successively arranged at intervals in the left-right direction on both of the two synchronous beams 901 and form four groups of manipulators one by one in a corresponding opposite manner. The four manipulators are defined as the first manipulator, the second manipulator, the third manipulator and the fourth manipulator. The first manipulators of the two synchronous beams 901 form a group of manipulators, the second manipulators of the two synchronous beams 901 form a group of manipulators, the third manipulators of the two synchronous beams 901 form a group of manipulators, and the fourth manipulators of the two synchronous beams 901 form a group of manipulators. Thus, four groups of manipulators are formed; the manipulator 91 is an L-shaped plate, which includes a horizontal support plate portion 911 and a vertical abutting plate portion 912. The horizontal support plate portion 911 is used to support the tray basket upward, and the vertical abutting plate portion 912 is used to abut and limit the tray basket inward. Each of the manipulators is connected to the synchronous beam 901 through a YZ-axis driving mechanism. The YZ-axis driving mechanism drives the corresponding manipulator so that the manipulator can displace along the Z-axis and the Y-axis relative to the synchronous beam 901. The left-right direction is defined as the X-axis direction, the front-back direction is defined as the Y-axis direction, and the up-down direction is defined as the Z-axis direction. The synchronous beam 901 is connected to an X-axis driving mechanism 902. The X-axis driving mechanism 902 drives the synchronous beam 901 to displace along the X-axis, so that the four groups of manipulators are correspondingly connected and reciprocate between the stack lifting loading device 20 and the liquid injection device 30, between the liquid injection device 30 and the standing device 40, between the standing device 40 and the sealing device 50, and between the sealing device 50 and the stack lifting discharging device 60 to convey and carry the tray basket carrying a number of battery cells. In this embodiment, the X-axis driving mechanism 902 includes a motor 9A, a rotating shaft 9B driven by the motor 9A to rotate, and synchronous belts 9C respectively arranged at both ends of the rotating shaft 9B. The motor 9A is arranged at the front side or the rear side. The rotating shaft 9B extends in the front-back direction. The synchronous belts 9C are respectively located at the front and rear sides of the rack 10. The two synchronous beams 901 are respectively connected to the corresponding synchronous belts 9C to translate left and right along with the synchronous belts 9C. The YZ-axis driving mechanism includes a Z-axis driving cylinder 903 and a Y-axis driving cylinder 904. The cylinder body of the Z-axis driving cylinder 903 is connected to the synchronous beam 901. The cylinder body of the Y-axis driving cylinder 904 is connected to the telescopic rod of the Z-axis driving cylinder 903 to displace up and down under the drive of the Z-axis driving cylinder 903. The telescopic rod of the Y-axis driving cylinder 904 drives the manipulator to displace along the Y-axis.

[0043] The liquid injection device 30 includes a liquid injection assembly and a liquid injection support base. The liquid injection assembly is located above the liquid injection support base. The liquid injection assembly includes a plurality of liquid injection heads 31, a liquid injection lifting drive mechanism 32 for driving the plurality of liquid injection heads 31 to move up and down, and a liquid injection translation drive mechanism 33 for driving the plurality of liquid injection heads 31 to move along the Y-axis. A first tray basket placement position is provided at the top of the liquid injection support base. The number of battery cells placed on the tray basket 100 is more than the number of liquid injection heads. By means of the plurality of liquid injection heads 31 moving translationally along the Y-axis, the battery cells can be injected one by one. A smaller-sized liquid injection device 30 and a smaller number of liquid injection heads can meet the liquid injection requirements for a larger number of battery cells. Since sufficient space needs to be reserved for the arrangement of the liquid injection heads, while the battery cells can be placed densely, breaking the inherent thinking in the industry that "the number of liquid injection heads is the same as the number of battery cells", it is possible to realize that a plurality of battery cells in one tray basket are sent in at a time, far exceeding the number of liquid injection heads, and still be quickly completed within one production cycle. The liquid injection support base 34 is connected to a liquid injection support base lifting mechanism 35 and a liquid injection support base translation mechanism 36. The liquid injection support base lifting mechanism 35 drives the liquid injection support base 34 to move up and down, and the liquid injection support base translation mechanism 36 drives the liquid injection support base 34 to move along the Y-axis.

[0044] The static device 40 includes a static base 41 and a static cavity 42 provided above the static base 41. A second tray basket placement position is provided at the top of the static base 41. The static cavity 42 is connected to a static cavity lifting drive mechanism 43. The static cavity lifting drive mechanism 43 drives the static cavity 42 to move up and down to cover the upper part of the second tray basket placement position or move upward away from the second tray basket placement position.

[0045] The sealing device 50 includes a sealing base 51 and a plurality of sealing clamping components 52 arranged above the sealing base 51. A third tray basket placement position is provided at the top of the sealing base 51. The plurality of sealing clamping components 52 are connected to a sealing clamping drive mechanism 53 and a sealing lifting drive mechanism 54. Each sealing clamping component includes clamping pieces arranged on the left and right opposite sides. The opposite surfaces of a group of clamping pieces are both provided with corrugated surfaces. Usually, a heating element is embedded in the clamping pieces. The sealing clamping drive mechanism drives the plurality of sealing clamping components to clamp towards each other and open away from each other, and the sealing lifting drive mechanism drives the plurality of sealing clamping components to move up and down. In this embodiment, the sealing clamping drive mechanism 53 is a lateral clamping cylinder, which drives two clamping connection ends, dividing all the clamping pieces into two parts. That is, the left clamping pieces of all the sealing clamping components are one part 521, and the right clamping pieces of all the sealing clamping components are the other part 522. The two parts are each separate components, and the two parts are respectively connected by the two clamping connection ends. In this way, one drive realizes the sealing operation of all the battery cells. The sealing base 51 is connected to a sealing base lifting mechanism, and the sealing base lifting mechanism drives the sealing base to move up and down.

[0046] The stack lifting loading device 20 and the stack lifting unloading device 60 both include a support plate 22 and a stack lifting mechanism 23. The stack lifting mechanism 23 is connected to the support plate 22 to drive the support plate 22 to move up and down. The top surface of the support plate 22 is used to store the tray basket stacks.

[0047] The tray basket 100 has a surrounding frame and a plurality of battery cell placement positions arranged within the surrounding frame. Here, the plurality of battery cell placement positions are designed as three columns with a left-right spacing, and each column includes 12 battery cell placement positions arranged side by side with a front-back spacing. Considering production and manufacturing, generally, the tray basket 100 is made of insulating plastic material and is separately injection-molded into two parts, namely a main frame 100A and an inner frame 100B. Then, the inner frame 100B is stacked on the main frame 100A from top to bottom. Specifically, the surrounding frame is arranged on the main frame 100A. The main frame 100A includes a front side wall, a rear side wall, a left side wall, a right side wall, and two intermediate ribs connected between the front side wall and the rear side wall. The two intermediate ribs are arranged with a left-right spacing. The front side wall, the rear side wall, the left side wall, and the right side wall form the surrounding frame. A U-shaped claw A1 is arranged on the left side of the left side wall. Grooves A2 are arranged on the front side of the front side wall and the rear side of the rear side wall. The grooves A2 penetrate downward to the bottoms of the corresponding front side wall and the rear side wall, so that the inner side surfaces and the inner top surfaces of the grooves are retained on the front side wall and the rear side wall. When the manipulator 91 extends into the groove A2, the horizontal support plate portion 911 forms an upward support for the inner top surface of the groove, and the vertical backing plate portion 912 forms an inward abutting limit for the inner side surface of the groove. At the four corners of the top of the surrounding frame, there are raised feet A3 extending upward. At the bottom corresponding to the positions of the raised feet at the four corners of the surrounding frame, there are positioning notches A4. For adjacent tray baskets 100 stacked up and down, the top of the raised foot A3 of the lower tray basket 100 extends into the positioning notch of the upper tray basket 100 to obtain assembly positioning.On the left side of the two middle ribs and the left side of the right wall, a number of first battery cell placement positions A5 arranged side by side at intervals in the front and rear directions are integrally formed. These first battery cell placement positions A5 are all open on the left side and open on the top. The inner frame 100B includes a front connecting rod B1, a rear connecting rod B2, and three connecting rods B3 connected between the front connecting rod B1 and the rear connecting rod B2. The three connecting rods B3 are arranged at intervals in sequence from left to right, and a number of second battery cell placement positions B4 arranged side by side at intervals in the front and rear directions are integrally formed on the right side of the three connecting rods B3. These second battery cell placement positions B4 are open on the right side and open on the top, and insertion posts B5 are arranged at the lower part near the right side of the three connecting rods B3. Correspondingly, a slot A6 is arranged at the lower part near the left side of the first battery cell placement position A5. When the inner frame 100B is assembled downward from the top of the main frame 100A, the front connecting rod B1 and the rear connecting rod B2 are respectively located at the tops of the front side wall and the rear side wall. The second battery cell placement positions B4 are spliced to the left side of the corresponding first battery cell placement positions A5 to form corresponding battery cell placement positions. The insertion posts B5 are then embedded into the corresponding slots A6. Further, retaining buckles A7 are also arranged at the tops of the front side wall and the rear side wall. After the inner frame 100B is installed on the main frame 100A, the front connecting rod B1 and the rear connecting rod B2 are stuck in the gap between the retaining buckles A7 and the step surface, that is, the retaining buckles A7 are used to prevent the inner frame 100B from slipping out upward. After the battery cells are placed on the battery cell placement positions, their liquid injection ports are arranged upward. When the battery cells enter and leave the equipment, they are in the form of a whole tray. Structures (such as profiling positioning) that match and position the outer shape of the tray basket 100 are arranged at the first tray basket 100 placement position, the second tray basket 100 placement position, and the third tray basket 100 placement position.

[0048] Next, the working process of the linear battery liquid injection machine will be introduced:

[0049] 1. A number of battery cells have been placed and positioned in the tray basket 100. For example, they are arranged in a 12*3 vertical and horizontal layout. Of course, other quantities are also possible. A number of tray baskets 100 are stacked on the trolley 80. The trolley 80 is pushed into the trolley push-in position 70, and then the whole stack is transferred to the stack lifting and feeding device 20.

[0050] 2. The synchronous conveying device 90 takes a tray of battery cells from the top of the stack lifting and feeding device 20 and transfers them to the liquid injection station. The tray basket 100 is sent to the first tray basket 100 placement position, and the battery cells on the tray basket 100 are injected with liquid by the liquid injection device 30.

[0051] 3. After the liquid injection is completed, the tray basket 100 is transferred by the synchronous conveying device 90 to the static placement station. The tray basket 100 is sent to the second tray basket 100 placement position, and the battery cells on the tray basket 100 are evacuated and statically placed by the static placement device 40.

[0052] 4. After the static placement is completed, the tray basket 100 is transferred to the sealing station by the synchronous conveying device 90. The tray basket 100 is sent to the placement position of the third tray basket 100, and the air extraction and sealing device is carried out on the battery cells on the tray basket 100 by the sealing device 50;

[0053] 5. After the encapsulation is completed, the tray basket 100 is transferred to the blanking station by the synchronous conveying device 90, that is, the processed whole tray basket 100 is stacked on the stacking lifting and blanking device 60;

[0054] 6. The whole stack is unloaded from the stacking lifting and blanking device 60 to the trolley by the trolley; with the cooperation of the second conveyor belt assembly 21 and the first conveyor belt assembly 71, the whole stack of tray baskets 100 is translated from the stacking lifting and blanking device 60 to the trolley.

[0055] After the operation is stable, the synchronous conveying device 90 simultaneously transfers the tray basket 100 between the stacking lifting and loading device 20 and the injection device 30, between the injection device 30 and the static placement device 40, between the static placement device 40 and the sealing device 50, and between the sealing device 50 and the stacking lifting and blanking device 60. That is to say, there are three trays of battery cells on the tray basket 100 in the in-line injection machine undergoing processing operations at the same time. It is equivalent to completing the processing and output of the battery cells on one tray basket 100 within the unit time T. After actual measurement, at least 100 battery cells can be processed per minute. This conveying method is simple and has good controllability. For fully automated equipment, its electronic control algorithm is simplified and the operation reliability is better.

[0056] As Figure 18 shown, if a dedicated trolley pushing-in position 70 is not set, the second conveyor belt assembly 21 of the stacking lifting and loading device 20 and the stacking lifting and blanking device 60 can be cancelled. It is equivalent to directly setting a trolley pushing-in position on the stacking lifting and loading device 20 and the stacking lifting and blanking device 60. For example, after the trolley 80 enters the stacking lifting and loading device 20, the support plate 22 is located below the bottommost tray basket of the trolley 80 to form a support, and the stacking lifting mechanism 23 drives the support plate 22 to move upward, then the whole stack of tray baskets is lifted upward. Similarly, on the blanking side, after the trolley enters the stacking lifting and blanking device 60, the support plate hangs above. After receiving the first tray basket, it gradually descends until the whole stack is full. At this time, the bottommost tray basket is supported on the trolley.

[0057] The design focus of the present utility model lies in that there are successively arranged a stack lifting and loading device 20, a liquid injection device 30, a standing device 40, a sealing device 50 and a stack lifting and unloading device 60 on a frame 10 in the left-right direction. Moreover, a synchronous conveying device 90 is connected between each device. The synchronous conveying device 90 includes two synchronous beams 901 arranged at a front-rear interval and extending in the left-right direction. Four manipulators are successively arranged at intervals in the left-right direction on each of the two synchronous beams 901, and the four manipulators are arranged in pairs facing each other one by one to form four groups of manipulators. Each manipulator is connected to the synchronous beam 901 through a YZ-axis driving mechanism. The YZ-axis driving mechanism drives the corresponding manipulator, so that the manipulator can displace along the Z-axis and the Y-axis relative to the synchronous beam 901. The synchronous beam 901 is connected with an X-axis driving mechanism 902. The X-axis driving mechanism 902 drives the synchronous beam 901 to displace along the X-axis.
