DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0048] The utility model provides a conveying stepping line. The conveying line provided by the utility model can be applied to various industries with product conveying needs. For the convenience of explanation, this application is described by taking battery cell conveying as an example.

[0049] See also Figure 1 and Figure 2 The conveying stepping line includes: a fixed bracket 100, a mobile bracket 200 and a driving component. The mobile bracket 200 is arranged between the fixed brackets 100. The fixed bracket 100 and the mobile bracket 200 are both used to support the battery cells. The mobile bracket 200 controlled by the driving component drives the battery cells to move forward between the fixed brackets 100, which can improve the stability of the material during transportation. The battery cells are first loaded onto the fixed bracket 100, and then the mobile bracket 200 is driven by the driving component to perform reciprocating movements of rising, moving forward, descending, and retreating in sequence, that is, the battery cells are repeatedly supported by changing hands between the fixed bracket 100 and the mobile bracket 200, driving the battery cells along a straight line direction (i.e. Figure 1 The battery is moved forward (in the X-axis direction) to realize the conveying operation of the battery cells.

[0050] Specifically, the fixing bracket 100 is along Figure 1There are N fixed brackets 100 in the X-axis direction, where N is an integer of 2, 3, etc. Each fixed bracket 100 includes two profiles that are spaced apart and arranged in parallel. The fixed bracket 100 is used to support the four corners of the battery cell to provide a stable supporting force for the battery cell when it is stationary.

[0051] Specifically, M mobile brackets 200 can be accommodated between the two profiles of each fixed bracket 100, where M is an integer of 2, 3, ..., and each mobile bracket 200 includes a profile arranged parallel to the fixed bracket 100, and adjacent mobile brackets 200 are fixedly connected, wherein the mobile bracket 200 is used to support the middle position of the bottom surface of the battery cell to provide stable supporting force for the battery cell during transportation.

[0052] Specifically, the driving component includes an active component and a driven component arranged in a straight line direction, and the sum of the number of active components and driven components is adapted to the number of mobile brackets 200; the active component drives several driven components to move synchronously to ensure the accurate transportation of the battery cells and avoid the problem of position deviation during transportation. During the transportation process, the single action stroke of the active component can synchronously drive the battery cells on the entire conveyor line to move forward synchronously as a whole, ensuring the position stability of the battery cells during transportation and reducing the problem of position deviation caused by long-distance transportation. It should be noted that the active component and driven component shown in the accompanying drawings of the utility model are only one embodiment. In actual application, one or more active components can be added to a certain transportation length according to the transportation load requirements of the battery cells, and several driven components can be synchronously dragged to avoid the problem of high-load operation of the equipment and damage caused by excessive load of a single active component.

[0053] In one embodiment, see Figure 2 and Figure 3The fixed bracket 100 is provided with a first positioning block 101, and the first positioning block 101 has a concave platform adapted to the four corners of the battery cell. Four first positioning blocks 101 are formed into a group to support the four corners of the battery cell. The four first positioning blocks 101 in a group are evenly arranged on two profiles. The fixed bracket 100 is provided with multiple groups of first positioning blocks 101, which can support multiple battery cells for simultaneous transportation; the mobile bracket 200 is provided with a supporting platform 201, and the supporting platform 201 is provided with a second positioning block 202, and the second positioning block 202 has a long strip concave platform adapted to the two ends of the bottom surface of the battery cell. The two second positioning blocks 202 are a group of supporting the middle part of the bottom surface of the battery cell. The movable bracket 200 is provided with multiple groups of second positioning blocks 202, wherein each group of first positioning blocks 101 and each group of second positioning blocks 202 are arranged in a one-to-one correspondence; when the battery cell is located on the fixed bracket 100, the four corners of the battery cell are limited by the four first positioning blocks 101, so that the battery cell can be kept in a stable state and not easy to move when it is stationary; when the movable bracket 200 supports the battery cell, the two second positioning blocks 202 limit the two sides of the battery cell, and also keep the battery cell in a stable state and not easy to move when it moves.

[0054] In one embodiment, see Figure 6 The position of the first positioning block 101 on the fixed bracket 100 is adjustable, that is, the first positioning block 101 can be slid along the extension direction of the profile to adjust the position; specifically, each first positioning block 101 is connected to the profile by a T-bolt, a slot is provided on the profile, and a strip connected to the T-bolt is provided inside the profile; when in use, the first positioning block 101 can be slid along the profile according to the width size of the battery cell to be delivered, until the spacing between a group of first positioning blocks 101 for supporting a single battery cell is adapted to the width size of the battery cell, and the position of the first positioning block 101 for limiting the battery cell can be adjusted to adapt to the adjustment, and the applicability is high.

[0055] Preferably, see Figure 6 A scale 102 is provided on the profile side wall of the fixed bracket 100, and each group of first positioning blocks 101 corresponds to two scales 102, that is, the two first positioning blocks 101 located on the same profile share one scale 102, and each scale 102 is provided with two scale lines. The first positioning block 101 is provided with a marking piece that is movably fitted with the surface of the scale 102. When the position of the first positioning block 101 needs to be adjusted, the adjusted distance of the first positioning block 101 can be fed back in real time through the scale 102, which is convenient for the staff to clearly observe the adjusted position and realize precise adjustment.

[0056] In one embodiment, the mobile bracket 200 is configured to support 60% of the area of ​​the bottom of the material. In this embodiment, by supporting the large area of ​​the bottom of the battery cell by the mobile bracket 200, a stable support force can be provided for the transportation of heavy objects such as the battery cell, ensuring the stability during the transportation process; it should be noted that the area supported by the mobile bracket 200 can float up and down, and what needs to be ensured is that it can support the large area of ​​the battery cell to meet the requirement of maintaining stability.

[0057] In one embodiment, see Figure 1 The active component includes a first driving component 300 and a second driving component 400. The first driving component 300 and the second driving component 400 act in the following five states to drive the moving bracket 200 to move and drive the battery cell to be transported;

[0058] Specifically, in the first state, the movable bracket 200 is located at a first height below the support surface defined by the fixed bracket 100; in this state, the movable bracket 200 is not in contact with the bottom surface of the battery cell, and the movable bracket 200 is at the first height position waiting for the battery cell to be placed on the fixed bracket 100;

[0059] In the second state, the first driving component 300 is used to raise the mobile bracket 200 to a second height above the supporting surface; in this state, after the battery cell is placed on the fixed bracket 100, the first driving component 300 drives the mobile bracket 200 to rise along the Z-axis direction, and continues to rise after the mobile bracket 200 contacts the battery cell, so that the battery cell is supported by the fixed bracket 100 and then switched to the mobile bracket 200 until it rises to the second height and stops, thereby realizing the battery cell switching between the fixed bracket 100 and the mobile bracket 200.

[0060] In the third state, the second driving component 400 is used to move the movable bracket 200 forward P workstations in a straight direction; in this state, the second driving component 400 drives the movable bracket 200 located at the second height position to move P workstations along the X-axis direction, where P is an integer of 1, 2, etc., thereby driving the battery cells located on the movable bracket 200 to move forward along the X-axis direction to realize the forward movement.

[0061] In the fourth state, the first driving component 300 is used to lower the movable bracket 200 to the first height; in this state, the first driving component 300 lowers the movable bracket 200 after moving forward P stations at the second height, and when the supporting surface to which the movable bracket 200 is lowered is coplanar with the supporting surface of the fixed bracket 100, the four corners of the battery cells on the movable bracket 200 contact the first positioning blocks 101 on the fixed bracket 100, and then the movable bracket 200 continues to descend and detaches from the battery cells, so that the fixed bracket 100 supports the battery cells alone. At this time, the battery cells move P stations along the X-axis direction from the station in the first state, and the movable bracket 200 stops until it descends to the first height, thereby realizing the switching of supporting of the battery cells between the movable bracket 200 and the fixed bracket 100.

[0062] In the fifth state, the second driving component 400 is used to reset the movable bracket 200 to the position in the first state along a straight line. In this state, the second driving component 400 continues to drive the unloaded movable bracket 200 to move in the opposite direction of the X-axis until it stops at the position in the first state, completing the reset action.

[0063] In summary, the first driving component 300 and the second driving component 400 cooperate with each other to drive the movable bracket 200 to perform reciprocating movements of ascending, advancing, descending, and retreating in sequence, thereby realizing the step-by-step conveying operation of the battery cells.

[0064] In one embodiment, see Figure 2-Figure 4The first driving component 300 includes a first linear slide 301, which is arranged on one side of the moving bracket 200 along the X-axis direction to provide a driving force for the moving bracket 200 to move up and down along the Z-axis direction. The first linear slide 301 can also be replaced by a device that can provide a linear drive function, such as a guide rail pair or a linear motor; a first slide connecting plate 302 is provided on the first linear slide 301, and the first slide connecting plate 302 is a rectangular plate structure with a hollow middle portion. The first slide connecting plate 302 is connected to the movable portion at the bottom of the first linear slide 301; the first slide connecting plate 302 is oriented toward the moving bracket 200. A push block 304 is connected to one side of the push block 304. The top of the push block 304 is an inclined surface and the bottom is a horizontal surface. The bottom of the push block 304 slides with the linear guide 305 through a slider, and the top slides with the bottom of the inclined bracket 303. By driving the push block 304 to slide along the linear guide 305, the inclined bracket 303 slidably connected to it can be pushed and moved, so that the inclined bracket 303 moves along the Z axis. The linear guide 305 is set below the movable bracket 200 along the X axis. The length of the linear guide 305 satisfies that at least the battery cell can move one station along the X axis. The linear guide 305 The inclined plane bracket 303 is arranged on a workbench for support; the top of the inclined plane bracket 303 is a horizontal plane, and the bottom is an inclined plane. The push block 304 slides along the linear guide rail 305, and the push block 304 slides along the inclined plane of the inclined plane bracket 303, and the inclined plane bracket 303 is pushed and moved along the Z-axis direction; the top of the inclined plane bracket 303 is connected to the slide rail 307, and the slide rail 307 is arranged in a direction parallel to the linear guide rail 305, and the slide rail 307 can be vertically slidably limited between a pair of vertical slide rails 306, and the vertical slide rail 306 is fixed on the support column, and the slide rail 307 is used to provide an X-axis direction for the mobile bracket 200 The movable bracket 308 has a movable bearing function in the direction of the X-axis, and a pair of vertical slide rails 306 limit the slide rail 307, so that the slide rail 307 maintains stability when it is lifted or lowered along the Z-axis direction; a slidable movable bracket 308 is provided on the slide rail 307, which has a rectangular structure. The top of the movable bracket 308 is fixedly connected to the movable bracket 200, and the bottom is slidably matched with the slide rail 307. The movable bracket 308 can be slidably arranged on the slide rail 307, providing the movable bracket 308 with a movable bearing function along the X-axis direction, so that the movable bracket 308 can drive the movable bracket 200 to move forward along the X-axis direction under the drive of the second driving component 400.

[0065] Specifically, when the first driving component 300 is in motion, the first linear slide 301 drives the first slide connecting plate 302 to move linearly along the battery cell conveying direction, and synchronously drives the pushing block 304 to move along the linear guide rail 305. Since the pushing block 304 slides with the inclined surface of the inclined surface bracket 303, the pushing block 304 pushes the inclined surface bracket 303 upward during the movement, and then synchronously drives the movable bracket 308 located on the slide rail 307 to move upward, and finally pushes the movable bracket 200 connected to the movable bracket 308 to move upward, thereby realizing the lifting function of the movable bracket 200. When driving the movable bracket 200 to descend, it can be realized by driving the pushing block 304 to move in the opposite direction.

[0066] In one embodiment, see Figure 3 and Figure 5 The second driving component 400 includes a second linear slide 401, which is arranged on the other side of the moving bracket 200 along the X-axis direction to provide driving force for the moving bracket 200 to move linearly along the X-axis direction. The first linear slide 301 can also be replaced by a guide rail pair or a linear motor or other equipment that can provide a linear drive function; a second slide connecting plate 402 is provided on the second linear slide 401. The second slide connecting plate 402 is a rectangular plate structure with a hollow middle portion, and is connected to the movable portion of the second linear slide 401; the second slide connecting plate 402 is connected to the front of the vertical guide rail 403 toward the side wall of the moving bracket 200, and the vertical guide rail 403 is connected to the second slide connecting plate The connecting plate 402 is slidably matched, and the back of the vertical guide rail 403 is connected to the movable bracket 308. When the first driving component 300 drives the movable bracket 200 to rise and fall, the movable bracket 308 moves accordingly with the second slide connecting plate 402 through the vertical guide rail 403. At this time, the second slide connecting plate 402 is in a stationary state. When it is necessary to drive the movable bracket 200 forward, the second slide connecting plate 402 is driven to move along the X-axis direction through the second linear slide 401, ensuring that the first driving component 300 and the second driving component 400 do not interfere with each other, and each can independently complete the function of driving the movable bracket 200 to rise and fall and move forward and backward.

[0067] Specifically, when the second driving component 400 is in motion, the second linear slide 401 drives the second slide connecting plate 402 to make a linear motion along the battery cell conveying direction, and the second slide connecting plate 402 synchronously drives the movable bracket 200 to move along the slide rail 307 along the X-axis direction through the vertical guide rail 403, thereby realizing the function of driving the movable bracket 200 to move forward and backward.

[0068] In one embodiment, see Figure 2 and Figure 3The conveying stepping line of the utility model also includes an adjusting slide rail 500, which is arranged below the profile of the fixed bracket 100, and is arranged along the arrangement direction perpendicular to the fixed bracket 100 and along the Y-axis direction. At least one profile in the fixed bracket 100 is arranged on the adjusting slide rail 500, and the profile slides with the adjusting slide rail 500 through a slider. Two adjusting slide rails 500 are arranged below each profile, which are respectively connected to the two ends of each profile through sliders. The adjusting slide rail 500 is fixed on the bracket, and the bracket is fixed on the supporting column; specifically, when it is necessary to adjust the spacing between two profiles, one of the profiles is moved along the Y-axis direction, and the other remains stationary, or the two profiles are moved on the adjusting slide rail 500 along the Y-axis direction at the same time to realize the spacing adjustment function; that is, when in use, the spacing between the two profiles can be adjusted according to the length of the battery cell to meet the conveying operation of battery cells of different lengths. Among them, the movement of the profile can be manually operated or automatically operated by equipment such as a cylinder.

[0069] Preferably, the adjustment rail 500 is provided with a scale; by setting the scale, the staff can observe the adjustment position more clearly, thereby ensuring the accuracy of the spacing position adjustment between the two profiles.

[0070] Please note that Figure 7 The structure of the driven component is the same as part of the structure of the active component. Specifically, the first linear slide 301 and the first slide connecting plate 302 are removed from the first driving component 300 in the active component, and the entire second driving component 400 is removed, and the remaining structure is the structure of the driven component; specifically, the active component and the driven component and the adjacent driven components are connected through a connecting rod 600, and the two ends of the connecting rod 600 are respectively connected to the bottom slider of the push block 304 in their respective components. When the driving component provides lifting power, the power of the active component can be transmitted to the driven component through the connecting rod 600, so that the moving bracket 200 connected to the driven component moves synchronously. When the driving component provides forward power, the linear power can be transmitted because the adjacent moving brackets 200 are fixedly connected to each other.

[0071] During the operation of the stepping conveyor line of the present application, the incoming battery cells are placed on the fixed bracket 100 in sequence. At this time, the fixed bracket 100 supports the battery cells alone, and the movable bracket 200 is located at a first height position below the supporting surface defined by the fixed bracket 100. Subsequently, the first driving component 300 performs the first driving, and the first linear slide 301 drives the first slide connecting plate 302 to move along the X-axis direction, driving the push block 304 to move in the same direction along the linear guide rail 305, and gradually pushing the inclined bracket 303 to rise along the Z-axis direction. The movable bracket 308 synchronously drives the movable bracket 200 to rise. When the movable bracket 200 rises and contacts the bottom of the battery cell, it continues to rise until the battery cell is lifted to the second height above the support surface defined by the fixed bracket 100 and stops, completing the first step; the second driving component 400 performs a second drive, and the second linear slide 401 drives the second slide connecting plate 402 to move along the X-axis direction, driving the movable bracket 308 to move in the same direction along the slide rail 307, thereby driving the movable bracket 200 to maintain the second height and move forward along the X-axis direction. The first driving component 300 performs the third driving, and the first linear slide 301 drives the first slide connecting plate 302 to move in the opposite direction along the X-axis direction, and synchronously drives the push block 304 to move in the same direction, so that the inclined plane bracket 303 gradually descends in the opposite direction along the Z-axis direction, so that the movable bracket 308 synchronously drives the movable bracket 200 to descend, and when the movable bracket 200 drives the battery cell to descend to the supporting surface where the fixed bracket 100 is located, it continues to descend until the movable bracket 200 is separated from the battery cell and is supported by the fixed bracket 100. The bracket 100 supports the battery cell again by itself, and the movable bracket 200 stops at the first height below the supporting surface of the fixed bracket 100, completing the third step; the second driving component 400 drives for the fourth time, and the second linear slide 401 drives the second slide connecting plate 402 to move in the opposite direction along the X-axis direction, so that the movable bracket 308 moves in the same direction along the slide rail 307, driving the movable bracket 200 to reset to the initial position at the first height, completing the fourth step; the above actions are repeated in a cycle to realize the step-by-step loading of the battery cell.

[0072] Since the driving component includes an active component and a driven component, the active component moves as described above, and the driven component follows the active component to perform synchronous movements, thereby enabling the battery cells on the entire conveyor line to perform synchronous conveying movements. Through cyclic reciprocating movements, the battery cells on the entire conveyor line can perform continuous stepping movements, thereby ensuring the precise transmission of the battery cells.

[0073] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.

[0074] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated.
