Description

[Technical field]

[0001] The invention relates to the field of battery cell group pressing, in particular to a battery cell pressing and transfer integrated device. [Background technology]

[0002] Lithium-ion battery modules are assembled from several single lithium-ion cells. One product process is to stack two cells into a pair, and then stack pairs of cells into modules. Multiple modules that have been welded in series are transported to the battery box for assembly.

[0003] Module stacking is an important part of power battery assembly production, and is related to the product quality and safety of the entire power battery pack. In the past, battery cell gluing and stacking were mostly done manually, with poor dimensional accuracy and reliability that could not be fully guaranteed. Manual processing was subject to uncertainty, high risk, and poor reliability. The existing stacking process of the automatic production line is: unloading, positioning, clamping, pressing, rotating, and taking out materials. Each workstation is usually used to complete one process action, and horizontal transfer is used between workstations. The disadvantages are that there are many workstations, the production line is long, the equipment occupies a large space, the efficiency is low, and the cost is high. At present, there is no production line equipment on the market that combines multiple actions of the above stacking process in one assembly.

[0004] The defects of the existing technology are mainly manifested in: 1. The mechanism is large, the structure is complex, the debugging is difficult, the equipment is long, and the space occupied is large. 2. The multi-station step-by-step action mechanism adds a lot of sensors, which increases the cost of the electrical system. 3. The multi-station step-by-step action mechanism increases the risk of mechanism abnormality due to the large number of mechanisms. 4. The existing technology multi-station step-by-step action must have a lot of pneumatic components, etc., which leads to a bottleneck of slow production rhythm, and is not suitable for the increasingly high production line production rhythm requirements. [Summary of the invention]

[0064] In the description of the present invention, it is necessary to understand that the description indicating the orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention.

[0065] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "disposed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0066] The overall concept of the present invention is as follows:

[0067] (1) The turntable 1 is driven by the first rotary drive mechanism 2 to transport the battery cell to the next station, i.e., the station changes. The turntable 1 has two or more stations, corresponding to a number of pressing mechanisms 3, and adopts a rotary layout, which can shorten the length of the production line, and the station change and battery cell pressing action can be carried out simultaneously, thereby improving work efficiency.

[0068] (2) In the embodiment shown in the drawings, there are four pressing mechanisms 3 on the turntable 1, which can be grouped in pairs, that is, two pressing mechanisms 3 can discharge, press, and take materials at the same time, and perform synchronously, thereby further improving work efficiency. Of course, in other embodiments, the pressing mechanisms 3 can also be of other numbers, and the pressing mechanisms 3 that perform pressing each time can be one or more than one, and can be arranged according to actual needs.

[0069] (3) The pressing mechanism 3 works simultaneously during the rotation of the turntable 1. The cell pressing work includes: a. unloading; b. cell positioning; c. cell clamping; d. cell pressing; e. the cell pressing mechanism rotates 90 degrees and unclamps. The pressing mechanism 3 integrates various actions in the existing process into one, improves the production cycle, reduces the number of workstations and equipment, simplifies the structure of the production line, and reduces the hardware costs of electronic components, structural parts, etc.

[0070] See also Figures 1 to 12 shown.

[0071] A battery cell pressing and indexing integrated device 100 of the present invention comprises:

[0072] Turntable 1; used to arrange the pressing mechanism 3, realize the rotary workstation, and shorten the length of the production line;

[0073] A first rotary drive mechanism 2, the output end of which is connected to the turntable 1, drives the turntable 1 to rotate, realizes the station change, and conveys the battery cell to the next station after pressing;

[0074] There are several pressing mechanisms 3, which are fixedly connected to the turntable 1, and the several pressing mechanisms 3 are evenly arranged in a clockwise or counterclockwise circle with the rotation center of the turntable 1, that is, they are arranged symmetrically with the rotation center of the turntable, so that the turntable 1 rotates at a predetermined angle, and at least one pressing mechanism is at a discharge station to be pressed; at least one pressing mechanism 3 that has completed the pressing of the battery cell is at a station where the battery cell to be pressed is to be taken out, and the pressing mechanism 3 completes the pressing work during the rotation of the turntable 1, so that the station change, pressing, and transportation to the next station can be carried out simultaneously, thereby improving work efficiency.

[0075] The pressing mechanism 3 comprises:

[0076] A support frame 31, fixedly connected to the turntable 1;

[0077] The battery cell support 32 has an open right-angle receiving cavity 321 for accommodating the battery cell 200 and is rotatably connected to the support frame 31;

[0078] The second rotary drive device 33 is fixedly connected to the support frame 31, and the output end is connected to the battery cell holder 32, driving the battery cell holder 32 to rotate. This can be set according to actual use requirements. For example, the structure of the robot arm in the next process requires the battery cell holder 32 to be selected 90° before the battery cell 200 can be taken out. Therefore, the rotation function of the second rotary drive device 33 and the battery cell holder 32 is set. If in other embodiments, the robot arm in the next process does not need to rotate the battery cell holder 32, and the battery cell can be taken out after the unclamping is completed, then the second rotary drive device 33 is not needed. In a specific implementation, the second rotary drive device 33 can use actuators such as motors and rotary cylinders.

[0079] The clamping and positioning mechanism 34 includes a first clamping drive device 341 and a first clamping plate 342; the first clamping drive device 341 is fixedly connected to the turntable 1 or the support frame 31, and the output end is fixedly connected to the first clamping plate 342, and drives the first clamping plate 342 to move along a direction perpendicular to an inner side surface of the right-angle accommodating chamber 321; wherein the first clamping plate 342 is also arranged parallel to and facing an inner side surface of the right-angle accommodating chamber 321; after the first clamping plate 342 presses the battery cell, the battery cell can slide along a direction parallel to the rotation axis of the battery cell holder 32; that is, the battery cell should not be pressed to death, which can be achieved by debugging the stroke of the first clamping drive device 341 in actual production. Similarly, the second clamping plate 352 is the same, pressing the battery cell on the other side, but not to death, so that the battery cell can slide, so that the clamping mechanism 36 can press the two battery cells 200 together.

[0080] The clamping mechanism 35 comprises a second clamping driving device 351, a second clamping plate 352, a fixing seat 353 and an avoidance driving device 354; the avoidance driving device 354 is fixedly connected to the battery holder 32, and the output end is fixedly connected to the fixing seat 353, and drives the fixing seat 353 to move along a direction perpendicular to an inner side surface of the right-angle accommodating cavity 321; the second clamping driving device 351 is fixedly connected to the fixing seat 353, and the output end is fixedly connected to the second clamping plate 352, and drives the second clamping plate 352 to move along a direction perpendicular to the other inner side surface of the right-angle accommodating cavity 321; wherein the second clamping plate 352 and the other inner side surface of the right-angle accommodating cavity 321 are arranged parallel to each other;

[0081] The clamping mechanism 36 includes a pressing drive device 361 and a third pressing plate 362; the pressing drive device 361 is fixedly connected to the battery holder 32, and the output end is fixedly connected to the third pressing plate 362, and drives the third pressing plate 362 to move in a direction parallel to the rotation axis of the battery holder 32; wherein the third pressing plate 362 and the two inner side surfaces of the right-angle accommodating cavity 321 are perpendicular to each other.

[0082] The pressing mechanism 3 also includes:

[0083] A locking drive device 37, fixedly connected to the support frame 31;

[0084] A latch pin 38, fixedly connected to the output shaft of the locking drive device 37;

[0085] The battery support 32 also has a plurality of pin holes 322;

[0086] The locking drive device 37 drives the pin 38 to insert into or withdraw from one of the pin holes 322, so as to limit the battery holder 32 to prevent rotation due to accidental failures such as gas or power failure during the pressing, taking or releasing process.

[0087] The pressing mechanism 3 also includes:

[0088] The detection device 39 is fixedly connected to the battery holder 32 and is used to detect whether the battery 200 is properly placed in the right-angled receiving cavity 321 to meet the use requirements of automated production. If the detection device 39 is not provided, it is suitable for semi-automated production. For example, a start button can be provided. After the battery is placed in the right-angled receiving cavity 321, the start button is manually pressed, and each driving device works according to a predetermined program. The detection device 39 detects whether the battery is properly placed, which includes two functions: first, whether the battery is properly placed; second, whether there is a battery in the right-angled receiving cavity 321.

[0089] In a specific embodiment, the detection device 39 adopts a proximity sensor, that is, a proximity switch, and there are two of them, which serve as a double insurance. They are fixed in one side of the right-angle accommodating cavity 321 and arranged according to the sensing distance of the proximity sensor. For example, if the sensing distance is 2mm, only the battery cell within the range of 2mm can be sensed, which means that it is placed in place. At this time, it is sensed that there is a battery cell and that the battery cell is placed in place, and then feedback is given to the control device, which then controls each drive device to work and press it.

[0090] The support frame 31 includes:

[0091] The left bracket 311 is fixedly connected to the turntable 1;

[0092] The right bracket 312 is fixedly connected to the turntable 1 and spaced apart from the left bracket 311;

[0099] There are two guide shafts 355, which are arranged perpendicular to an inner side surface of the right-angle accommodating cavity 321;

[0100] There are two linear bearings 356 , which are sleeved on the guide shaft 355 in a one-to-one correspondence and are respectively embedded in the fixing seat 353 .

[0106] In a specific embodiment, the two inner sides of the right-angle accommodating cavity 321, the inner side of the first pressing plate, and the inner side of the second pressing plate are also provided with pads, and the material of the pads is non-metallic materials such as nylon; the pads, the first pressing pads 4, and the second pressing pads 5 are all made of nylon, rubber, or other non-metallic materials, so that during the pressing process, soft contact is achieved with each surface of the battery cell 200 to avoid scratching the surface of the battery cell.

[0108] Motor 21;

[0109] The cam divider 22 has an input shaft connected to the output shaft of the motor, and an output shaft fixedly connected to the rotary disk. The motor 21 drives the cam divider 22 to drive the rotary disk 1 to rotate.

[0110] Specific usage:

[0111] There are four pressing mechanisms 3. When grabbing materials and pressing, two pressing mechanisms 3 work synchronously, that is, two stations work synchronously. The number of pressing mechanisms 3 working synchronously can be determined according to the number that the material discharging manipulator can grab. In other embodiments, other numbers can also be used.

[0112] The second rotary drive device 33 adopts a rotary cylinder;

[0113] The first pressing drive device 341, the second pressing drive device 351, the avoiding drive device 354, the pressing drive device 361 and the locking drive device 37 are respectively cylinders;

[0114] The detection device 39 adopts a proximity sensor.

[0115] The motor 21, the second rotation drive device 33, the first clamping drive device 341, the second clamping drive device 351, the avoidance drive device 354, the pressing drive device 361, the locking drive device 37, and the detection device 39 are respectively communicatively connected to the control device of the production line, such as PLC, to achieve unified control.

[0116] Preset working procedures:

[0117] In the initial state, the battery holder 32 is rotated to 0°. Figure 4 , Figure 5, Fig. 9 The locking drive device 37 drives the pin to be inserted into the pin hole 322 at the bottom of the battery holder 32, and restricts the battery holder 32 in the circumferential direction to prevent rotation. Fig.10 shown.

[0118] During production, the control device is installed with a predetermined program to control the unloading robot to grab the battery cells that have been glued and are waiting to be pressed and put them into the right-angle accommodating cavity 321, and simultaneously put them into the two pressing mechanisms 3;

[0119] After placement, the control device controls the material taking robot to exit and take the next group of battery cells; synchronously, the battery cell 200 in the right-angle accommodating cavity 321 is sensed by the detection device 39, and a feedback signal is given to the control device, indicating that the battery cell has been placed in place and the next operation can be carried out;

[0120] After receiving the feedback signal from the detection device 39, the control device performs a pressing action: synchronously controlling the first pressing drive device 341 and the second pressing drive device 351 to drive the first pressing plate 342 and the second pressing plate 352 to press the two sides of the battery cell, but not to death. At this time, the battery cell 200 can move along the rotation axis direction of the battery cell holder 32; then controlling the pressing drive device 361 to push the battery cell 200 to move to one end of the battery cell holder 32 to a predetermined position, pressing and bonding the two battery cells 200 together, and maintaining the pressure for a certain time, such as 5s.

[0121] Working synchronously with the above-mentioned pressing action, the control device controls the motor 21 to drive the turntable to rotate 180°, and rotates the other two pressing mechanisms 3 to the current position to be discharged; then the control device controls the discharge manipulator to grab the next group of battery cells into the two pressing mechanisms 3 for pressing the next group of battery cells;

[0122] On the other hand, the cells in the two pressing mechanisms 3 that have completed or are in the process of pressing rotate to the material taking station; after reaching the predetermined holding time:

[0123] The control device first controls the first clamping drive device 341 to drive the first clamping plate 342 to unclamp, and simultaneously controls the locking drive device 37 to drive the latch 38 to exit the latch hole 322;

[0124] Then the second rotation driving device 33 is controlled to work, driving the battery holder 32 to rotate 90°. Figure 6 , Figure 7 , Fig.11 and Fig.12 At this time, the bottom end of the battery holder 32 also has a latch hole 322, and the latch 38 cooperates with the battery holder 32 to limit the position. The latch hole is not shown in the figure, and can be seen in Fig.10 As shown, the pin-hole fit is similar to that at 0°.

[0125] After the rotation is in place, the locking drive device 37 is controlled to drive the latch 38 to be inserted into another latch hole 322 at the bottom, so as to limit the battery holder 32 and prevent accidental rotation.

[0126] Then the second clamping driving device 351, the pressing driving device 361 and the avoiding driving device 354 are controlled to drive the second clamping plate 352 and the third clamping plate 362 to unclamp, and the second clamping plate 352 also retreats to avoid the side of the battery cell to avoid interference when taking out the material;

[0127] Then control the material taking robot to take away the pressed cells in the two pressing mechanisms 3;

[0128] Finally, the locking drive device 37 is controlled to drive the latch 38 to exit the latch hole 322, and then the second rotation drive device 33 is controlled to drive the battery holder 32 to rotate and reset to the 0° state, and then the locking device 37 is controlled to drive the latch 38 to insert into the latch hole 322;

[0129] The previous step can synchronously control the motor 21 to work, drive the turntable 1 to rotate, and so on, to perform the reciprocating cycle of discharging and pressing the battery cells, and rotate to the next station to take out the materials.

[0130] The locking drive device 37 drives the latch 38 to exit the latch hole 322 only when the battery holder 32 rotates from 0° to 90°, or resets from 90° to 0°. The locking drive device 37 drives the latch 38 to insert into the latch hole 322 and is in a locked state during the rest of the working time.

[0131] Among them, Figure 1 In the embodiment shown, there are four laminating mechanisms 3, indicating four laminating workstations. In other embodiments, the laminating mechanisms 3 may also adopt other numbers, that is, the number of workstations of the laminating mechanisms 3 may be selected according to the needs.

[0132] On the other hand, the turntable 1 can rotate 1 / 2 circle, 1 / 3 circle, 1 / 4 circle... etc. each time. At the same time, during each rotation, one pressing mechanism 3 can perform pressing, or two or more pressing mechanisms can perform pressing at the same time, that is, the number of workstations of the turntable 1 rotation and the number of pressing mechanisms 3 that perform pressing synchronously can be pre-set according to actual needs.

[0133] Although the specific implementation modes of the present invention are described above, those skilled in the art should understand that the specific implementation modes described are only illustrative and are not intended to limit the scope of the present invention. Equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the present invention should be included in the scope of protection of the claims of the present invention.
