Description

Technical Field

[0001] This utility model belongs to the field of battery production and relates to cell shaping technology, specifically a cell module shaping device. Background Technology

[0002] The main purpose of cell module shaping is to improve the flatness of the cell module in the height direction, eliminate the deformation and stress that may occur during the production process, improve the internal space utilization of the cell, and thus improve the structural and safety performance of the cell module. Through shaping, it is ensured that the cell module can be stably installed in the battery pack or module shell, thereby improving the reliability and service life of the battery.

[0003] The reference patent is titled: Battery Cell Module Shaping Device (Patent Publication No.: CN219246743U). By pre-placing the battery cell module on a fixture, and then transporting the fixture carrying the battery cell module to the shaping station through the conveying unit, the shaping unit shapes the battery cell module, saving the time of manual handling, improving the shaping efficiency, and realizing automated production.

[0004] However, the following problems exist when implementing the above technical solutions: Both the above solutions and the existing battery cell module shaping devices require manual arrangement of the battery cells on a certain structural surface before the shaping work. This process requires manual handling of multiple battery cells to the platform or structural surface, which involves repeated work and high labor intensity. Prolonged physical labor can lead to fatigue, muscle injury and other problems for the operators. Furthermore, after shaping, the cells need to be moved to the next process, which relatively prolongs the overall operation time.

[0005] Therefore, this utility model proposes a battery cell module shaping device. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a battery cell module shaping device, which solves the problem that existing battery cell module shaping devices require repeated handling of the battery cell modules before and after shaping multiple cells, resulting in high labor intensity and long processing times.

[0007] To achieve the above objectives, a battery cell module shaping device is provided according to an embodiment of the first aspect of this utility model, comprising two horizontal shaping plates and a vertical shaping plate, both of which are slidably connected to the interior of a frame, and a conveyor belt is slidably connected to the interior of the frame; a shaping mechanism is provided between the horizontal and vertical shaping plates and the frame, the shaping mechanism comprising:

[0008] A contact block is slidably connected to the inside of the frame. The contact block and the longitudinal straightening plate are symmetrically arranged relative to the center line of the transverse straightening plate. An electric telescopic rod is fixedly connected to one end of the contact block. A contact block is fixedly connected to the end of the electric telescopic rod away from the contact block. A contact spring is fixedly connected between the contact block and the frame. A brush is fixedly connected to the end of the contact block away from the contact block.

[0009] The machine includes a drive column and two drive columns, both of which are rotatably connected to the inside of the frame. One end of the drive column is fixedly connected to a commutator, and the end of the commutator away from the drive column is fixedly connected to a rotor. One end of both the drive column and the drive columns is fixedly connected to a commutator cone, which mesh with each other. The drive column and the transverse plate are threaded together.

[0010] A passive column is rotatably connected to a drive column. A connecting belt is fixedly connected between the passive column and the longitudinal straightening plate. A spiral groove is opened inside the drive column. A passive shaft is rotatably connected to the surface of the passive column, and the passive shaft is adapted to the spiral groove.

[0011] Optionally, the cross-section of the longitudinal plate is a right trapezoid with an arc-shaped hypotenuse, and one side of the arc-shaped hypotenuse faces the contact block.

[0012] Optionally, the drive column and the driving column are slidably connected to an adjusting rod, the reversing cone wheel is fixedly connected to one end of the adjusting rod, and the driven column slides inside the adjusting rod.

[0013] Optionally, the surface of the adjusting rod is provided with a sliding groove, and the surfaces of the driving column and the drive column are rotatably connected with a locking shaft, and the sliding groove is adapted to the locking shaft.

[0014] Optionally, the locking shaft is V-shaped, opening to the left or right half, and a through groove is provided at the turning point. A through rod is fixedly connected inside both the driving column and the drive column, and the through groove is adapted to the through rod.

[0015] Optionally, a torsion spring is sleeved on the surface of the through rod, and the two ends of the torsion spring are respectively fixed to the drive column or the driving column and the locking shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: the battery cells are directly conveyed from the previous process to the machine frame via a conveyor belt, and the position changes of the longitudinal and transverse aligning plates are achieved by the position change of the sliding contact blocks. When the battery cell module pushes the contact block to the commutator position, the drive column will rotate under the action of electromagnetic reaction, thereby causing both the drive column and the moving column to rotate. The transverse aligning plate moves closer to the battery cell module, making it easier to align the two sides. At the same time, the passive column slides, causing the longitudinal aligning plate to slide down and contact the battery cell module, ensuring that there are no gaps inside the battery cell module. After the battery cell module is shaped, the electric telescopic rod and the conveyor belt can be driven to move the battery cell module to the next process. At the same time, reverse current can be applied to the brushes, and the aligning plate will reset. After the battery cell module is separated from the contact block, the contact block resets under the action of the spring, waiting for the arrival of the next battery cell module. Thus, during the battery cell module shaping process, the operator only needs to operate the electric telescopic rod and the current direction, which reduces the workload. Moreover, the movement of the battery cell module is directly transported by the conveyor belt, which is more convenient. Attached Figure Description

[0026] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figure 1-6 As shown, a battery cell module shaping device includes two horizontal shaping plates 1 and a vertical shaping plate 2. The horizontal shaping plates 1 and the vertical shaping plates 2 are slidably connected to the inside of a frame 3. The adjacent horizontal shaping plates 1 and the vertical shaping plates 2 are in contact with the adjacent surfaces of the battery cell module. A conveyor belt 4 is slidably connected inside the frame 3.

[0028] It should be noted that the length of the conveyor belt 4 is greater than the distance between the longitudinal straightening plates 2. The conveyor belt 4 transports the battery cells to the position of the transverse straightening plate 1 and transfers them to the next process. The transverse straightening plate 1 is parallel to the edge of the conveyor belt 4, and the longitudinal straightening plate 2 is perpendicular to the edge of the conveyor belt 4.

[0029] A shaping mechanism is provided between the horizontal shaping plate 1, the vertical shaping plate 2, and the frame 3. The shaping mechanism includes:

[0030] Contact block 51 is slidably connected to the inside of frame 3. Contact block 51 and longitudinal straightening plate 2 are symmetrically arranged relative to the center line of transverse straightening plate 1. An electric telescopic rod is fixedly connected to one end of contact block 51 away from conveyor belt 4. A power receiving block is fixedly connected to one end of electric telescopic rod away from contact block 51. A contact spring 52 is fixedly connected between power receiving block and frame 3.

[0031] There is a gap between the contact block 51 and the conveyor belt 4, and a support plate (not shown in the figure) is provided between the contact block 51 and the frame 3 to achieve sliding and position limitation;

[0032] It should be noted that the power receiving block has a built-in mobile power supply (not shown in the figure), and the electric telescopic rod is electrically connected to the mobile power supply (not shown in the figure);

[0033] A brush is fixedly connected to one end of the power receiving block away from the contact block 51, and the brush is electrically connected to the mobile power supply (not shown in the figure).

[0034] The drive column 53 and two drive columns 54 are rotatably connected to the inside of the frame 3. One end of the drive column 53 is fixedly connected to a commutator, which is in contact with the brush. The end of the commutator away from the drive column 53 is fixedly connected to a rotor.

[0035] It should be noted that two arc-shaped magnets (not shown in the figure) with different polarities are fixedly connected at a certain distance on the frame 3, and the distance between the two arc-shaped magnets (not shown in the figure) and the rotor is fixed; then when the brush moves to contact the commutator, the electromagnetic reaction will cause the drive column 53 to rotate; the thread length on the surface of the drive column 53 and the drive column 54 is limited.

[0036] One end of each of the drive column 53 and the driving column 54 is fixedly connected to a reversing cone wheel 55, the reversing cone wheels 55 mesh with each other, the driving column 54 is threadedly connected to the horizontal plate 1, and the thread directions on the surfaces of the two driving columns 54 are opposite.

[0037] Passive column 56 is rotatably connected to drive column 53, and a connecting strip 57 is fixedly connected between passive column 56 and longitudinal plate 2.

[0038] It should be noted that a guide post is fixedly connected inside the frame 3, and the connecting strip 57 is slidably connected to the surface of the guide post.

[0039] The drive column 53 has a spiral groove 58 inside, and the passive column 56 has a passive shaft 59 rotatably connected to its surface. The passive shaft 59 is adapted to the spiral groove 58.

[0040] In practical application, this battery cell module shaping device directly transports the battery cells from the previous process to the machine frame 3 via conveyor belt 4. The position of the longitudinal shaping plate 2 and the transverse shaping plate 1 changes through the positional change of the sliding contact block 51. When the battery cell module pushes the contact block 51 to the commutator position, the drive column 53 rotates under the action of electromagnetic reaction, causing both the drive column 53 and the driving column 54 to rotate. The transverse shaping plate 1 moves closer to the battery cell module, facilitating alignment on both sides. Simultaneously, the passive column 56 slides, causing the longitudinal shaping plate 2 to slide down, aligning the longitudinal shaping plate 2 with the battery cell. The module contacts ensure that there are no gaps inside the battery cell module. After the battery cell module is shaped, the electric telescopic rod and conveyor belt 4 can be driven to move the battery cell module to the next process. At the same time, reverse current can be applied to the brushes, and the whole board will be reset. After the battery cell module is separated from the contact block 51, the contact block 51 is reset under the action of the spring, waiting for the arrival of the next battery cell module. Thus, during the battery cell module shaping process, the operator only needs to operate the electric telescopic rod and the current direction, which is relatively less labor-intensive. Moreover, the movement of the battery cell module is directly transported by the conveyor belt 4, which is more convenient.

[0041] In some specific implementations, the cross-section of the longitudinal straightening plate 2 is a right trapezoid with an arc-shaped hypotenuse, one side of which faces the contact block 51. The longitudinal straightening plate 2 is elastic, so that when the longitudinal straightening plate 2 contacts the battery cell, the battery cell can slide along the arc-shaped hypotenuse to change its position, and the longitudinal straightening plate 2 can make the left and right battery cells fit together tightly.

[0042] In some specific implementations, the drive column 53 and the driving column 54 are internally slidably connected to an adjusting rod 61, and the reversing cone wheel 55 is fixedly connected to one end of the adjusting rod 61. The passive column 56 slides internally with the adjusting rod 61. Thus, the distance between the longitudinal straightening plate 2 and the contact block 51 and the distance between the transverse straightening plates 1 can be adjusted, which facilitates the shaping of battery cell modules with different numbers of internal battery cells.

[0043] In a further embodiment, the adjusting rod 61 has a sliding groove 62 on its surface, and the driving column 53 and the driving column 54 are rotatably connected to a locking shaft 63. The sliding groove 62 is adapted to the locking shaft 63. The locking shaft 63 is V-shaped, opening to the left or right half, and has a through groove at the turning point. The driving column 53 and the driving column 54 are both fixedly connected to a through rod 65. The through groove is adapted to the through rod 65. A torsion spring 64 is sleeved on the surface of the through rod 65. The two ends of the torsion spring 64 are fixed to the inside of the driving column 53 or the driving column 54 and the locking shaft 63, respectively. After rotating the locking shaft 63, the locking shaft 63 and the sliding groove 62 can be disengaged. At this time, the position between the adjusting rod 61 and the driving column 54 and the driving column 53 can be changed. After the locking shaft 63 is released, it will reset under the action of the torsion spring 64, thereby restricting the position of the driving column 53 and the driving column 54.

[0044] In a further embodiment, several spacer blocks are fixedly connected to the surfaces of the drive column 53 and the driving column 54, and several support blocks are slidably connected inside the frame 3. The opposite sides of adjacent spacer blocks and support blocks are fitted together. Cylindrical grooves are formed on the surfaces of the support blocks, and the cylindrical grooves are adapted to the drive column 53 and the driving column 54. A return spring is fixedly provided between the support block and the driving column 54, and an operating rod is threadedly connected inside the support block. The operating rod can then drive the support block to move. When the locking shaft 63 is disengaged from the sliding groove 62, the movement of the support block can cause the positions of the driving column 54 and the driving column 53 and the adjusting rod 61 to change, which facilitates more precise adjustment of the position of the horizontal plate 1.

[0045] The working principle of this utility model:

[0046] When the conveyor belt 4 is running, the conveyed battery cell contacts the contact block 51, and under the action of the subsequent battery cell and the conveyor belt 4, the contact block 51 moves. The movement of the contact block 51 causes the brush to move. After the brush moves to contact the commutator, the commutator drives the drive column 53 to rotate. The rotation of the drive column 53 causes the drive column 54 to rotate through the commutation cone wheel 55. At the same time, the passive column 56 slides inside the drive column 53 to change its position. The movement of the passive column 56 causes the connecting belt 57 to move, and then the longitudinal straightening plate 2 and the transverse straightening plate 1 contact the battery cell module. After the three are completely in contact with the battery cell, the contact block 51 can be moved upward and separated from the battery cell module by the electric telescopic rod. Then the battery cell module moves to the next process under the action of the conveyor belt 4. At the same time, the transverse straightening plate 1 is reset under the action of the reset spring, and the contact block 51 is reset under the action of the contact spring 52.

[0047] When adjusting the positions of the drive column 53 and the driving column 54, first rotate the locking shaft 63 to disengage the locking shaft 63 from the sliding groove 62. Then rotate the operating rod to make the support block slide. The sliding of the support block drives the drive column 53 and the driving column 54 to slide through the spacer block, changing the position between the two and the adjusting rod 61. After the adjustment is completed, release the locking shaft 63. Under the action of the torsion spring 64, the locking shaft 63 contacts the sliding groove 62, restricting the position of the drive column 53 and the driving column 54.

[0048] The above embodiments are only used to illustrate the technical methods of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of this utility model without departing from the spirit and scope of the technical methods of this utility model.
