Description

Technical Field

[0001] This application relates to the field of battery technology, specifically to an opening and transferring device and a packaging equipment. Background Technology

[0002] During the manufacturing process of cylindrical battery cells, before sealing the cells after winding, the air bag needs to be cut off. Before removing the air bag, the cell, including the wound core and the air bag connected to it, needs to be positioned using a transfer and positioning mechanism and transferred to a slicing device so that the slicing device can accurately remove the air bag.

[0003] Because of the different shapes of pouch cells and cylindrical cells, existing transfer and positioning mechanisms used for pouch cells cannot be directly used for the transfer and positioning of cylindrical cell cells. Manual transfer and positioning methods, on the other hand, pose risks of low efficiency and poor product process consistency.

[0046] Before explaining any implementation of this application in detail, it should be understood that this application is not limited to its application to the structural details and component arrangements set forth in the following description or shown in the above drawings.

[0047] In this application, the terms "comprising," "including," "having," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0048] In this application, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this application generally indicates that the preceding and following related objects have an "and / or" relationship.

[0049] In this application, the terms "connection," "combination," "coupling," and "installation" can refer to direct connection, combination, coupling, or installation, or indirect connection, combination, coupling, or installation. For example, a direct connection refers to two parts or components being connected together without the need for an intermediary, while an indirect connection refers to two parts or components each being connected to at least one intermediary, with the connection achieved through the intermediary. Furthermore, "connection" and "coupling" are not limited to physical or mechanical connections or couplings, but can also include electrical connections or couplings.

[0050] In this application, those skilled in the art will understand that relative terms (e.g., “about,” “approximately,” “basically,” etc.) used in conjunction with quantities or conditions are to include the values ​​and have the meaning indicated by the context. For example, such relative terms include at least the degree of error associated with the measurement of a particular value, tolerances associated with the particular value due to manufacturing, assembly, use, etc. Such terms should also be considered as disclosing a range defined by the absolute values ​​of the two endpoints. Relative terms may refer to a certain percentage (e.g., 1%, 5%, 10% or more) of the indicated value. Numerical values ​​not using relative terms should also be disclosed as specific values ​​with tolerances. Furthermore, “basically” when expressing relative angular relationships (e.g., substantially parallel, substantially perpendicular) may refer to a certain degree (e.g., 1 degree, 5 degrees, 10 degrees or more) added to or subtracted from the indicated angle.

[0051] In this application, those skilled in the art will understand that the function performed by a component can be performed by one component, multiple components, one part, or multiple parts. Similarly, the function performed by a part can also be performed by one part, one component, or a combination of multiple parts.

[0052] In this application, the directional terms "upper," "lower," "left," "right," "front," and "rear" are used to describe the orientation and positional relationships shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when an element is mentioned as being connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected through an intermediate element. It should also be understood that directional terms such as upper side, lower side, left side, right side, front side, and rear side not only represent positive orientation but can also be understood as lateral orientation. For example, "below" can include directly below, lower left, lower right, lower front, and lower rear.

[0053] like Figure 1 As shown, this application provides a packaging device for packaging a cylindrical battery cell 200. Before packaging the cell 200 after winding, the cell 200 includes a core portion 201 and an air bag 202 connected to the core portion 201. The core portion 201 of the cell 200 needs to be positioned to facilitate the removal of the air bag 202 from the cell 200.

[0054] The packaging equipment includes a cutting device and an opening and transferring device. The opening and transferring device is used to transfer the battery cell 200 and position the core portion 201 of the battery cell 200. The cutting device is used to cut off the air bag 202 of the battery cell 200 after it has been positioned by the opening and transferring device.

[0055] like Figures 1 to 2 As shown, the clamping and transferring device includes a frame 1, a support platform 2, a positioning clamp 3, a transfer mechanism 5, and a clamping drive mechanism 4. The frame 1 includes a horizontal plate 11, a first vertical plate 12, and a second vertical plate 13, which are erected parallel to each other on the horizontal plate 11. The support platform 2 and the positioning clamp 3 are both set independently of the frame 1. The support platform 2 is used to support the air bag 202 of the battery cell 200, and the positioning clamp 3 is used to clamp the core portion 201 of the same battery cell 200. The clamping drive mechanism 4 is installed on the horizontal plate 11 and the second vertical plate 13 and is used to keep the positioning clamp 3 in the open state. The transfer mechanism 5 is installed on the first vertical plate 12 and the second vertical plate 13 and is used to transfer the battery cell 200 to be positioned to the positioning clamp 3 so that the positioning clamp 3 can clamp the core portion 201 of the battery cell 200 to cooperate with the support platform 2 to position the battery cell 200.

[0056] In actual production, the battery cell 200 to be positioned is placed on the battery cell fixture 100, and then the first conveyor line transports the battery cell fixture 100 to the station of the transfer mechanism 5, so that the transfer mechanism 5 can transfer the battery cell 200 in the battery cell fixture 100 to the positioning fixture 3. In addition, after the positioning fixture 3 completes the positioning of the battery cell 200, the second conveyor line transports the positioning fixture 3 and the battery cell 200 on it to the next station for operation.

[0057] It should be noted that, Figures 1 to 2 The first and second conveyor lines are not shown in the diagram. The conveying directions of the first and second conveyor lines are the same as the extending direction of the core portion 201 of the battery cell 200, so that the transfer mechanism 5 can grasp the battery cell 200 on the first conveyor line and transfer it to the positioning clamp 3 on the second conveyor line. For better understanding of the technical solution of this application, the conveying directions of the first and second conveyor lines are defined as the first direction, i.e., the extending direction of the core portion 201; the direction in which the transfer mechanism 5 grasps the battery cell 200 and transfers it is defined as the second direction, i.e., the direction of the second conveyor line. Figure 2 The direction from the core jig 100 to the positioning fixture 3 is the second direction; Figure 2 The vertical direction is defined as the height direction, where the first direction and the second direction are perpendicular to each other.

[0058] It is worth noting that the first conveyor line has multiple cell fixtures 100, each holding a cell 200 to be positioned; the second conveyor line has multiple positioning fixtures 3. After the transfer mechanism 5 transfers the cells 200 from the cell fixtures 100 on the first conveyor line to the positioning fixtures 3 for positioning, the second conveyor line transports the positioned cells 200 to the next workstation for further processing. In other words, there are multiple positioning fixtures 3. After the positioning fixtures 3, in conjunction with the support platform 2, position the cells 200, the second conveyor line transports the positioning fixtures 3 and the cells 200 on them to the next workstation to meet the needs of automated production.

[0059] exist Figures 1 to 2 In the process, the transfer mechanism 5 includes a horizontal drive assembly 51, a vertical drive assembly 52, and a gripping assembly 53. The horizontal drive assembly 51 is mounted on the frame 1, the vertical drive assembly 52 is mounted on the output end of the horizontal drive assembly 51, and the gripping assembly 53 is mounted on the output end of the vertical drive assembly 52 and is used to grip the battery cell 200.

[0060] like Figure 3 Combination Figure 2As shown, in the transfer mechanism 5, the horizontal drive assembly 51 includes a horizontal driver 511 and a first mounting plate 512. The horizontal driver 511 is mounted on the frame 1, and its output end is connected to the first mounting plate 512 for driving the first mounting plate 512 to move along a second direction. The vertical drive assembly 52 includes a vertical driver 521 and a second mounting plate 522. The vertical driver 521 is mounted on the first mounting plate 512, and its output end is connected to the second mounting plate 522 for driving the second mounting plate 522 to move along a height direction. The gripping assembly 53 is mounted on the second mounting plate 522 and is used to grip the battery cell 200 to be positioned. In this embodiment, the horizontal driver 511 can be a cylinder, and the vertical driver 521 can also be a cylinder. In other embodiments, the horizontal driver 511 and the vertical driver 521 can be linear actuators such as linear motors and linear hydraulic cylinders, which will not be described in detail here.

[0061] The transfer mechanism 5 has two gripping components 53, which grip two battery cells 200 from two battery cell fixtures 100 each time and place the two battery cells 200 in two positioning jigs 3 respectively. Of course, in other embodiments, the transfer mechanism 5 may also have one gripping component 53, or three, four, five, six or more gripping components 53. Accordingly, the number of positioning jigs 3 is consistent with the number of battery cells 200 that the transfer mechanism 5 can grip at one time, so as to ensure that each battery cell 200 is equipped with one positioning jig 3.

[0062] Each gripping component 53 includes two suction cups 531, which simultaneously grip the winding core 201 of a battery cell 200 to ensure that the gripping component 53 can stably grip the battery cell 200 and prevent the battery cell 200 from falling off during transfer. In other embodiments, the gripping component 53 can also grip the battery cell 200 in other ways, such as by clamping or by clamping in conjunction with the suction cups 531.

[0063] In addition, the gripping component 53 also includes a limiting member 532, which extends along the height direction and is fixed to the second mounting plate 522, and the lower end of the limiting member 532 can abut against the air bag 202 of the battery cell 200. For example, a fixing block is fixed on the second mounting plate 522, extending along the second direction, and the limiting member 532 is fixed to the free end of the fixing block. In this embodiment, the two suction cups 531, in conjunction with one limiting member 532, ensure that the gripping component 53 can accurately grip the battery cell 200 and prevent the suction cups 531 from squeezing the core portion 201.

[0064] The transfer mechanism 5 also includes a horizontal guide assembly 54, which includes a guide sleeve 541 and a guide rod 542. The guide sleeve 541 is fixed to the frame 1, and the guide rod 542 is slidably engaged with the guide sleeve 541. One end of the guide rod 542 is fixedly connected to the first mounting plate 512. Figure 3 In the example shown, there are two horizontal guide components 54, which are arranged in parallel and spaced apart to ensure that the first mounting plate 512 moves stably in the second direction under the action of the horizontal driver 511.

[0065] In a horizontal guide assembly 54, there are two guide sleeves 541. One guide sleeve 541 is fixed to the first vertical plate 12, and the other guide sleeve 541 is fixed to the second vertical plate 13. A guide rod 542 cooperates with the two guide sleeves 541 to ensure the stability of the guide rod 542 moving in the second direction, thereby ensuring the stability of the first mounting plate 512.

[0066] The transfer mechanism 5 also includes a vertical guide assembly 55, which includes a slide rail 551 and a slider 552. The slide rail 551 is fixed to a first mounting plate 512, and the slider 552 is fixed to a second mounting plate 522. The slider 552 slides in cooperation with the slide rail 551. Figure 3 In the example shown, there are two vertical guide components 55, which are arranged in parallel and spaced apart to ensure that the second mounting plate 522 moves stably along the height direction under the action of the vertical driver 521.

[0067] like Figure 3 As shown, the output end of the vertical actuator 521 is movably connected to the first mounting plate 512. Specifically, the output end of the vertical actuator 521 has a second T-shaped block 5211, and the second mounting plate 522 has a second T-shaped groove 5221. The second T-shaped block 5211 of the vertical actuator 521 is inserted and engaged with the second T-shaped groove 5221, so that the output end of the vertical actuator 521 can move relative to the second mounting plate 522, avoiding the problem of stress concentration and fracture at the connection due to rigid connection.

[0068] Accordingly, such as Figure 4 As shown, the output end of the horizontal driver 511 is movably connected to the first mounting plate 512. Specifically, the output end of the horizontal driver 511 has a first T-shaped block 5111, and the first mounting plate 512 has a first T-shaped groove 5121. The first T-shaped block 5111 of the horizontal driver 511 is inserted and engaged with the first T-shaped groove 5121, so that the output end of the horizontal driver 511 can move relative to the first mounting plate 512, avoiding the problem of stress concentration and fracture at the connection due to rigid connection.

[0069] like Figures 5 to 6As shown, the positioning clamp 3 includes a support clamp 31 and a movable clamp 32. The movable clamp 32 is rotatably mounted on the support clamp 31 about a first pivot 10. The support clamp 31 has a first receiving groove 310 with the slot opening facing upward. The movable clamp 32 has a second receiving groove 320. The second receiving groove 320 can cooperate with the first receiving groove 310 to form a clamping cavity. The clamping cavity extends along a first direction and is used to accommodate the winding core portion 201 of the battery cell 200.

[0070] exist Figure 5 and Figure 6 In the example shown, both the first receiving groove 310 and the second receiving groove 320 are arc-shaped grooves, so that the clamping cavity formed by the first receiving groove 310 and the second receiving groove 320 can better accommodate and position the winding core 201 of the battery cell 200.

[0071] The movable clamp 32 includes a connecting part 321, a driving part 322, and a clamping part 323. The connecting part 321 is rotatably connected to the carrier clamp 31 via a first pivot 10. The first pivot 10 extends along a first direction. The driving part 322 and the clamping part 323 are located on both sides of the first pivot 10, and the driving part 322 is used to cooperate with the driving end of the clamping drive mechanism 4. The clamping part 323 is provided with a second receiving groove 320.

[0072] The support clamp 31 includes a fixing part 311 and a support part 312. At least two support parts 312 are spaced apart along a first direction and connected to the fixing part 311. One end of each support part 312 is provided with a groove 3120. All grooves 3120 cooperate to form a first receiving groove 310. At least one support part 312 has a pivot hole 3121. The adapter part 321 is rotatably engaged with the pivot hole 3121 through a first pivot 10. Figure 5 In the example shown, there are two carrier parts 312. In other embodiments, the number of carrier parts 312 can be one, three, four, or any other number, which is not limited here.

[0073] The positioning clamp 3 also includes an elastic element 33, which is located between the driving part 322 and the fixing part 311. The elastic element 33 is used to rotate the movable clamp 32 to a position where it cooperates with the bearing part 312 to clamp the core part 201. Under the elastic force of the elastic element 33, the movable clamp 32 can rotate to a position where it cooperates with the bearing part 312 to clamp the core part 201 of the battery cell 200. The clamping force provided by the elastic element 33 ensures that the movable clamp 32 and the bearing part 312 cooperate to elastically clamp the core part 201 of the battery cell 200, avoiding deformation of the core part 201 due to excessive clamping force.

[0074] In order to better install the elastic member 33, the surface of the driving part 322 facing the fixing part 311 has a first receiving hole 3221, and a portion of the elastic member 33 is accommodated in the first receiving hole 3221; the surface of the fixing part 311 facing the driving part 322 has a second receiving hole 3111, and a portion of the elastic member 33 is accommodated in the second receiving hole 3111.

[0075] In addition, when the movable clamp 32 rotates relative to the carrier clamp 31, in order to avoid interference between the clamping part 323 of the movable clamp 32 and the upper surface of the carrier clamp 31, the carrier part 312 of the carrier clamp 31 also has a relief groove 3122. The relief groove 3122 is used to avoid the clamping part 323 of the movable clamp 32, so as to ensure that the movable clamp 32 can rotate and open smoothly.

[0076] like Figures 7 to 8 As shown, the clamping drive mechanism 4 includes a clamping driver 41 and a lever 42. The clamping driver 41 is mounted on the frame 1 (specifically, the horizontal plate 11). The lever 42 is rotatably connected to the frame 1 (specifically, the second vertical plate 13) via a second pivot 20. The second pivot 20 extends along a first direction. The first end 42a and the second end 42b of the lever 42 are located on both sides of the second pivot 20, and the first end 42a is connected to the output end of the clamping driver 41. The second end 42b is located above the drive part 322 and can cause the drive part 322 to rotate downward and the clamping part 323 to rotate upward, so as to open the movable clamp 32 and put the carrying clamp 31 in an open state.

[0077] The number of positioning clamps 3 is at least two, and the at least two positioning clamps 3 are spaced apart along the first direction. The clamping drive mechanism 4 can simultaneously drive the movable clamps 32 of at least two positioning clamps 3 to rotate. The number of levers 42 is the same as the number of positioning clamps 3, and the levers 42 are arranged in a one-to-one correspondence with the movable clamps 32 of the positioning clamps 3.
