Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and in particular to a transfer connection structure, conveying device, equipment and method for battery cell transfer. Background Technology

[0002] In automated battery production lines, material flow typically employs methods such as pipeline conveying, conveyor belt conveying, and clamp conveying, depending on the material characteristics. In the mixing section, powder and liquid materials are primarily fed via pipeline conveying. Other sections of the production line utilize conveyor belts and clamp conveying depending on the cell flow and space requirements. Currently, clamp conveying is mainly used to handle the loading and unloading of materials by switching the angles of the front and rear conveyor belts. This method places certain requirements on the transfer equipment and technology, considering the characteristics of the transferred materials and the operating space, such as the rigidity of the clamps and their longitudinal movement. Furthermore, the clamps are prone to deformation, which can damage the bare cells being wound off the production line. This results in high costs, lack of continuity, and low efficiency.

[0003] By setting up a transfer station between conveyor belts and adjusting the rotation longitudinally to achieve stable transfer and transport of goods, a considerable gap is usually required between the transfer station and the front and rear logistics lines to avoid interference between the rollers of the transport components and the rollers of the preceding and following logistics lines when the rotating components of the transfer station drive the transport components to rotate. This can cause the materials to come loose during the transfer and transport process. At the same time, there are certain requirements and limitations on the longitudinal lifting space when the length, weight and angle of the conveying mechanism are adjusted.

[0004] Due to the limitations of production line site and space, in order to save on production line construction and production costs, automated battery production lines need to further address the issue of conveyor belt angle conversion and connection during cell transfer. Summary of the Invention

[0005] One of the technical problems that this invention aims to solve is that existing battery cell conveying methods are prone to deformation and damage to the bare battery cells after winding due to the use of clamping conveyor grippers, and the lifting mechanism requires spatial arrangement in the longitudinal direction. Furthermore, the conveyor belt conveyor requires a considerable gap between the conveyor and the preceding and following material lines, which leads to the possibility of material slippage during material connection and conveying. This results in high battery cell conveying costs and low production continuity and efficiency.

[0006] To address the aforementioned technical problems, a first aspect of this invention provides a relay connection structure for battery cell transmission.

[0007] The transit connection structure includes:

[0008] A guiding component, comprising a guide rail and a guiding drive, wherein the guide rail is disposed on the worktable and is used to drive the conveyor belt loaded with battery cells to reciprocate along the guide rail, so that the conveyor belt approaches the upstream / downstream conveyor belt, and the guide rail and the conveyor belt are arranged at an angle in the horizontal direction.

[0009] A rotating assembly, which supports the conveyor belt and is mounted on the guide rail, and is connected to the guide drive, to adjust the horizontal relative position of the conveyor belt and the guide rail to overlap with the upstream / downstream conveyor belt.

[0010] The transfer and connection structure provided by this invention, through the setting of a guiding component and a rotating component supporting the conveyor belt, allows the conveyor belt to reciprocate along the guide rail of the guiding component under the action of guiding drive, thereby approaching the upstream / downstream conveyor belt. Because the guide rail and the conveyor belt are set at an angle along the horizontal direction, the space required for the transfer and connection structure to support the movement of the conveyor belt is reduced. At the same time, the rotating component is used to adjust the relative position of the conveyor belt and the guide rail along the horizontal direction so that the upstream / downstream conveyor belt overlaps, avoiding the situation where the material transfer and conveying is detached due to excessive spacing between the conveyor belts. This solves the technical problems of high cost of battery cell transfer, low production continuity and low efficiency caused by the easy deformation and damage of the clamping conveyor grippers, the longitudinal space requirements of the lifting mechanism, and the need for a large gap between the conveyor belt transfer mechanism and the upstream and downstream material flow lines.

[0011] Preferably, the guide assembly includes a limiting member, which is disposed at least at one end of the guide rail opposite to the guide drive.

[0012] Preferably, the guide rail and the conveyor belt are set at an angle of 45° along the horizontal, and the rotating component adjusts the rotation angle of the conveyor belt to 90°.

[0013] Preferably, the rotating assembly includes a support bracket, a rotary motor, and a bearing. The support bracket is disposed below the conveyor belt and is connected to the rotary motor via the bearing.

[0014] Preferably, the guide drive includes a telescopic cylinder, which is connected to the rotating assembly.

[0015] A second aspect of the present invention provides a conveying device for transferring battery cells, the conveying device comprising a conveyor belt for loading battery cells and a transfer connection structure according to any of the above embodiments.

[0016] A third aspect of the present invention provides a conveying device for battery cell transport, the conveying device comprising an upstream conveyor belt, a downstream conveyor belt, and the aforementioned conveying apparatus.

[0017] A fourth aspect of the present invention provides a method for transporting battery cells, the method employing a transfer connection structure according to any of the above embodiments, the method comprising:

[0018] The rotating assembly supports the conveyor belt carrying the battery cells, and under the guidance and drive of the guiding assembly, it moves along the guide rail towards the upstream / downstream conveyor belt to the first position.

[0019] The rotating component adjusts the horizontal relative position of the conveyor belt and the guide rail at the first position so that the conveyor belt overlaps with the upstream / downstream conveyor belt.

[0020] Preferably, the operation of the rotating component is performed at intervals with the operation of the guide drive.

[0021] Preferably, the conveying method is used for a first operation to be conveyed to a downstream conveyor belt and a second operation to be conveyed to an upstream conveyor belt, wherein the first operation and the second operation have the same operation steps and opposite operation directions.

[0040] like Figures 1 to 8 As shown, this invention provides a transfer and connection structure for battery cell transfer. The transfer and connection structure includes a guiding component 1 and a rotating component 2. The guiding component 1 includes a guide rail 101 and a guiding drive 102. The guide rail 101 is mounted on a worktable 0 and drives a conveyor belt 3 carrying battery cells to reciprocate along the guide rail 101, so that the conveyor belt 3 approaches its upstream / downstream conveyor belt. The guide rail 101 and the conveyor belt 3 are arranged at an angle in the horizontal direction. The rotating component 2 supports the conveyor belt 3 and is mounted on the guide rail 101 and connected to the guiding drive 102, so that under the action of the guiding drive 102, the rotating component 2 and the conveyor belt 3 it supports move together. The rotating component 2 is used to adjust the relative position of the conveyor belt 3 and the guide rail 101 in the horizontal direction until they overlap with the upstream / downstream conveyor belt.

[0041] The transfer and connection structure provided by this invention, by setting a guiding component 1 and a rotating component 2 supporting the conveyor belt 3, allows the conveyor belt 3 to reciprocate along the guide rail 101 of the guiding component 1 under the action of the guiding drive 102, thereby approaching the upstream / downstream conveyor belt 3. Because the guide rail 101 and the conveyor belt 3 are set at an angle in the horizontal direction, the space required for the transfer and connection structure to support the movement of the conveyor belt 3 is reduced. Simultaneously, the rotating component 2 adjusts the relative position of the conveyor belt 3 and the guide rail 101 in the horizontal direction so that the upstream / downstream conveyor belt overlaps, avoiding excessive spacing between the conveyor belt 3 and the upstream / downstream conveyor belt, which could lead to material detachment during transfer and conveying. This solves the technical problems of high cost, low production continuity, and low efficiency in battery cell transfer caused by the easy deformation and damage to the wound bare battery cells by the clamping conveyor grippers, the longitudinal space requirements for lifting, and the need for considerable clearance between the conveyor belt transfer mechanism and the upstream and downstream logistics lines.

[0042] In an optional embodiment of the present invention, the guide assembly 1 includes a limiting member 103, which is at least disposed at one end of the guide rail 101 opposite to the guide drive 102, to limit the sliding distance of the conveyor belt 3 pushed by the guide drive 102 along the guide rail 101. In a further optional embodiment, the limiting member 103 can be disposed at different positions along the guide rail 101 according to actual needs, to adapt to the needs of different production sites. Optionally, multiple limiting members 103 can be disposed along the guide rail 101 for adjustment as needed. It should be noted that the limiting member 103 can be a physical limiter that sets a synapse to obstruct movement, or an electronic limiter that uses a sensor to sense and conduct to control the closing of the guide drive.

[0043] In an optional embodiment of the present invention, the guide rail 101 and the conveyor belt 3 are set at an angle of 45° along the horizontal, and the rotating component 2 adjusts the rotation angle of the conveyor belt 3 to 90°. This angle setting facilitates the site layout of the conveyor belt 3 and its upstream and downstream conveyor belts, avoiding mutual interference between the conveyor belt 3 and its upstream or downstream conveyor belts during operation. It also reduces the working space required for the conveyor belt 3 to be pushed and rotated for position adjustment, making the overall operation more flexible, thereby reducing production costs and improving production line efficiency. It should be noted that the length, width, and other related parameters of the conveyor belt 3 are set according to actual production needs and can be adjusted according to different production requirements. They are not fixed values, and since they are not part of the innovation of this invention, they will not be elaborated upon here.

[0044] In other optional embodiments of the present invention, the angle between the guide rail 101 and the conveyor belt 3 along the horizontal can be 30° or other values. The specific angle can be adjusted according to the actual production site. Similarly, the rotation angle of the rotating component 2 to adjust the rotation angle of the conveyor belt 3 can also be set according to the actual production line, and is not limited to the preferred embodiments of the present invention described above.

[0045] In a further optional embodiment of the present invention, the rotating component 2 includes a first rotation limiting member 204 and a second rotation limiting member 205 arranged at 90° intervals along the rotation direction. The arrangement of the first limiting member 204 and the second limiting member 205 helps to improve the accuracy of the rotation angle control of the rotating component 2 driving the conveyor belt 3. In other optional embodiments of the present invention, the angle, setting position, and number of the first limiting member 204 and the second rotation limiting member 205 can be adapted to meet the actual rotation angle control requirements. It should be noted that the first limiting member 204 and the second rotation limiting member 205 can be physical limits that set synapses to hinder movement, or electronic limits that use sensors to sense and conduct to control the closing of the guide drive. The specific adjustments can be made according to actual production needs.

[0046] In an optional embodiment of the present invention, the rotating assembly 2 includes a support bracket 201, a rotary motor 202, and a bearing 203. The support bracket 201 is disposed below the conveyor belt 3 and is connected to the rotary motor via the bearing 203. It should be noted that, in order to facilitate the rotating assembly 2 driving the conveyor belt 3 to rotate, the rotating assembly 2 can include any existing components that can be used to improve rotational accuracy, rotational force, or rotational precision, and is not limited to... Figure 1 The structure is simplified as shown in the figure. Similarly, in addition to the guide rail 101 and guide drive 102 shown in the figure, the guide rail assembly 1 may also include pulleys, rollers, balls, and rollers that are conventionally used to improve the smoothness of sliding, as well as various assembly frames and support components to ensure the structural integrity. The specific selection, replacement and modification of the guide rail assembly 1 can be made according to the actual production needs, which will not be described in detail here.

[0047] In an optional embodiment of the present invention, the guide drive 102 includes a telescopic cylinder 1021, which is connected to the rotating component 2. The telescopic cylinder 1021 can ensure that the conveyor belt 3 slides horizontally on the guide rail 101. The structure of the telescopic cylinder 1021 itself can effectively ensure the uniformity of the force applied to the conveyor belt 3 in the horizontal direction, thereby improving the accuracy of the conveying operation and improving production efficiency.

[0048] This invention provides a conveying device for transferring battery cells, comprising a conveyor belt 3 for loading battery cells and a transfer connection structure according to any of the above-described embodiments. The length of the conveyor belt 3 can be selected according to actual production needs.

[0049] The conveying device provided by this invention, by setting a guide component 1 and a rotating component 2 supporting the conveyor belt 3 in its transfer structure, allows the conveyor belt 3 to reciprocate along the guide rail 101 of the guide component 1 under the action of the guide drive 102, thereby approaching the upstream / downstream conveyor belt 3. Because the guide rail 101 and the conveyor belt 3 are set at an angle in the horizontal direction, the space required for the transfer structure to support the movement of the conveyor belt 3 is reduced. At the same time, the rotating component 2 is used to adjust the relative position of the conveyor belt 3 and the guide rail 101 in the horizontal direction so that the upstream / downstream conveyor belt overlaps, avoiding the situation where the material transfer and conveying is detached due to excessive spacing between the conveyor belt 3 and the upstream / downstream conveyor belt. This solves the technical problems of high cost of battery cell transfer, low production continuity and low efficiency caused by the easy deformation and damage of the clamping conveyor grippers, the longitudinal space requirements of the lifting mechanism, and the need for a large gap between the conveyor belt transfer mechanism and the upstream and downstream material flow lines.

[0050] The present invention provides a conveying device for battery cell transport, the conveying device comprising an upstream conveyor belt, a downstream conveyor belt and the aforementioned conveying apparatus.

[0051] The conveying device provided by the present invention, by setting a guide component 1 and a rotating component 2 supporting the conveyor belt 3 in the transfer and connection structure of its conveying device, enables the conveyor belt 3 to reciprocate along the guide rail 101 of the guide component 1 under the action of the guide drive 102, thereby approaching the upstream / downstream conveyor belt of the conveyor belt 3. Since the guide rail 101 and the conveyor belt 3 are set at an angle in the horizontal direction, the space required for the transfer and connection structure to support the movement of the conveyor belt 3 is reduced. At the same time, the rotating component 2 is used to adjust the relative position of the conveyor belt 3 and the guide rail 101 in the horizontal direction so that the upstream / downstream conveyor belt overlaps, avoiding the situation where the material transfer and conveying is detached due to the excessive gap between the conveyor belt 3 and the upstream / downstream conveyor belt. This solves the technical problems of high cost of battery cell transportation, low production continuity and low efficiency caused by the high deformation and damage of the clamps used in the conveyor transport, the long-distance spatial arrangement requirements of the lifting mechanism, and the large gap between the conveyor belt and the front and rear logistics lines.

[0052] This invention provides a method for transporting battery cells, the method employing the aforementioned relay connection structure, comprising:

[0053] The rotating assembly 2 supports the conveyor belt 3 carrying the battery cells. Under the guidance and drive 102 of the guiding assembly 1, it moves along the guide rail 101 towards the upstream / downstream conveyor belt of the conveyor belt 3 to a first position. It should be noted that this first position is preset according to production needs, and can be achieved by setting a limiting member 103 on the guide rail 101. The limiting member 103 can be a physical limit or an electronic limit that controls the closing of the guiding drive through sensor sensing and transmission. At this first position, the rotating assembly 2 adjusts the horizontal relative position of the conveyor belt 3 and the guide rail 101 so that the conveyor belt 3 overlaps with the upstream / downstream conveyor belt.

[0054] In an optional embodiment of the present invention, the operation of the rotating component 2 and the operation of the guide drive 102 are set at intervals, which can improve the adjustment efficiency during the operation, avoid the production process chaos caused by simultaneous operation, have a higher fault tolerance rate, make it easier to adjust the production line, have greater flexibility, and help improve production efficiency.

[0055] In an optional embodiment of the present invention, the conveying method is used for a first operation to be conveyed to a downstream conveyor belt and a second operation to be conveyed to an upstream conveyor belt. The first operation and the bottoming operation have the same operation steps and are in opposite directions.

[0056] Specifically, in actual use, when performing the first task, such as Figures 2 to 5 As shown, the rotating assembly 2 supports the conveyor belt 3 after the material receiving operation is completed. At this time, the drive motor of the conveyor belt 3 stops working, and the telescopic cylinder 1021 of the guide drive 102 pushes the rotating assembly 2 and the conveyor belt 3 to move along the guide rail 101 in the first direction A, so as to complete the horizontal translation movement of the conveyor belt 3 at 45°, and stop moving under the action of the limiting member 103. Figure 3 As shown. The rotary motor 202 drives the conveyor belt 3 to rotate 90° clockwise. The first limiting member 204 and the second limiting member 205 of the rotating assembly 2 are set at 90° along the rotation direction. At this time, the first limiting member 204 is disengaged, and the second limiting member 205 is engaged to ensure the accuracy of the clockwise rotation angle of the conveyor belt 3 driven by the rotating assembly 2, i.e., as shown. Figure 3 and Figure 4 As shown. The telescopic cylinder 1021 is activated, which drives the rotating assembly 2 and the conveyor belt 3 to move along the guide rail 101 in the second direction B, so as to complete the horizontal translation movement of the conveyor belt 3 at 45°, so that the conveyor belt 3 overlaps with the downstream conveyor belt, the drive motor of the conveyor belt 3 works, and the material is fed along the conveying direction of the conveyor belt 3.

[0057] During the second operation, the drive motor of conveyor belt 3 stops working, and the telescopic cylinder 1021 pushes the rotating assembly 2 and conveyor belt 3 to move along the guide rail 101 in a third direction C, completing a 45° horizontal translational movement of conveyor belt 3, where the third direction C is opposite to the second direction B. At this time, the limiting member 3 restricts the movement position of the rotating assembly 2 and conveyor belt 3 on the guide rail 101, keeping them in a preset first position. The rotating motor 202 drives the conveyor belt 3 to rotate counterclockwise by 90°. At this time, the second limiting member 205 disengages, and the first limiting member 204 engages to ensure the accuracy of the counterclockwise rotation angle of the rotating assembly 2 driving the conveyor belt 3, i.e., as... Figure 6 and Figure 7 As shown. The telescopic cylinder 1021 is activated, which drives the rotating assembly 2 and the conveyor belt 3 to move along the guide rail 101 in the fourth direction D. The fourth direction D is opposite to the first direction A, so as to complete the horizontal translation of the conveyor belt 3 at 45°, so that the conveyor belt 3 overlaps with the upstream conveyor belt, and then the material receiving operation is completed.

[0058] By repeating the above method, the transfer and connection structure, conveying device, equipment, and method for battery cell transfer provided by this invention achieve continuous conveying function of conveyor belt angle switching during battery cell flow in the lateral space. The device is flexible, reliable, and efficient. It effectively solves the technical problems of existing battery cell transfer methods, such as the easy deformation and damage of the clamping jaws to the wound bare battery cells, the spatial requirements for vertical arrangement of lifting mechanisms, and the need for a considerable gap between the conveyor belt transfer mechanism and the preceding and following material lines, which leads to material detachment during transfer and transfer, resulting in high battery cell transfer costs, low production continuity, and low efficiency.
