[0038] Example 1

[0039] See also Figures 1 to 4 As shown, the transfer device provided in the present application can be used in the battery production process. The transfer device can be set at the battery cell incoming station and the battery cell loading station to transfer the material frame 101 carrying the battery cells.

[0040] Specifically, the transfer device includes a carrier platform 102 and a transfer vehicle 103. The carrier platform 102 is used to carry the material frame 101, allowing the material frame 101 to travel back and forth between the two ends of the carrier platform 102 in the transport direction. The carrier platform 102 is provided with a parking area 104 to accommodate the transfer vehicle 103. The transfer vehicle 103 is used to transport the material frame 101. The transfer vehicle 103 includes a vehicle body 105 and a lifting platform 106. The lifting platform 106 is mounted on the vehicle body 105 and is used to transport the lifting platform 106. The lifting platform 106 is used to carry the material frame 101. When the vehicle body 105 is in the parking area 104, the lifting platform 106 can rise or fall relative to the carrier platform 102, allowing the material frame 101 to land on the higher lifting platform 106 or the higher carrier platform 102. Optionally, the vehicle body 105 is provided with a handle 107 to facilitate workers to push the transfer vehicle 103 to move.

[0041] Specifically, when a transfer device is provided at the cell incoming station, the transport platform 102 of the transfer device is connected to the sorting line of the previous process, so that the material frame 101 loaded with sorted cells can be transported from the sorting line to one end of the transport platform 102, and the transport platform 102 can transport the material frame 101 to the other end. When transferring the material frame 101 from the cell incoming station to the cell loading station, a worker can push the transfer vehicle 103 into the parking area 104. At this time, the height of the lifting platform 106 of the transfer vehicle 103 is lower than the height of the transport platform 102, and the weight of the material frame 101 falls on the transport platform 102. The lifting platform 106 then rises. When the lifting platform 106 rises to a height higher than the transport platform 102, the material frame 101 can fall on the lifting platform 106. The material frame 101 is then transferred from the transport platform 102 to the transfer vehicle 103, so that the transfer vehicle 103 can transport the material frame 101 to the cell loading station.

[0042] When the cell loading station is equipped with a transfer device, the direction of flow of the material frame 101 on the transfer device is exactly the opposite. A worker can push the transfer vehicle 103 carrying the material frame 101 into the parking area 104 of the transfer device. At this time, the height of the lift platform 106 of the transfer vehicle 103 is higher than the height of the carrier platform 102, and the weight of the material frame 101 falls on the lift platform 106. The lift platform 106 then descends. When the lift platform 106 descends to a height lower than the carrier platform 102, the material frame 101 can fall onto the carrier platform 102. The material frame 101 is then transferred from the transfer vehicle 103 to one end of the carrier platform 102, and the carrier platform 102 can transport the material frame 101 to the other end. A loading robot is installed at the other end of the carrier platform 102 to remove the battery cells from the material frame 101 and load them.

[0043] The transfer device provided in the present application can transfer the material frame 101 loaded with small batches of battery cells. Compared with forklifts with larger volume and energy consumption, this device has the advantages of simple structure, high efficiency and convenience, and flexible operation, which can reduce the cost of transporting small batches of battery cells.

[0044] In the optional solution of this embodiment, Figure 2 As shown, the loading platform 102 includes a support 108 and two conveying mechanisms 109; both conveying mechanisms 109 are mounted on the support 108. The two conveying mechanisms 109 are spaced apart to carry the material frame 101 from both ends. A parking area 104 is located between the two conveying mechanisms 109, and an entrance 110 is located at one end of the two conveying mechanisms 109 in the transport direction. The entrance 110 is connected to the parking area 104, allowing the transfer vehicle 103 to enter the parking area 104 through the entrance 110.

[0045] In this embodiment, when the carrier 102 transports the material frame 101, two conveying mechanisms 109 support the material frame 101 from both ends to ensure that the material frame 101 remains balanced, making the transport of the material frame 101 by the carrier 102 more stable. Furthermore, a parking area 104 and an entrance 110 are provided between the two conveying mechanisms 109. When the transfer vehicle 103 enters the parking area 104, the transfer vehicle 103 and the material frame 101 do not interfere with the conveying mechanisms 109. Furthermore, the two conveying mechanisms 109 are located on either side of the transfer vehicle 103, allowing the lift 106 of the transfer vehicle 103 to support the center of the material frame 101. This helps ensure that the material frame 101 remains balanced, making the transport of the material frame 101 by the transfer vehicle 103 more stable. Furthermore, when the material frame 101 is transferred between the lift 106 and the carrier 102, it is less likely to shift or fall.

[0046] It should be noted that the positional relationship between the parking area 104 and the loading platform 102 is not limited to the structure shown in the figure. Figure 2 The positional relationship between the parking area 104 and the loading platform 102 shown in the figure is as follows: the parking area 104 is located in the middle of the loading platform 102, so that the two conveying mechanisms 109 of the loading platform 102 can stably support the two ends of the material frame 101, and the lifting platform 106 of the transfer vehicle 103 can stably support the middle of the material frame 101. Optionally, the parking area 104 can also be located on one side of the loading platform 102, that is, when the transfer vehicle 103 carries the material frame 101, the lifting platform 106 supports half of the material frame 101, and when the transfer vehicle 103 transfers the material frame 101 to the loading platform 102, the loading platform 102 can support the other half of the material frame 101, but the stability of this method is lower than the stability of the structure shown in the figure.

[0047] In the optional solution of this embodiment, Figure 3 As shown, the conveying mechanism 109 includes multiple conveying rollers 111; the multiple conveying rollers 111 are arranged at intervals and are rotatably mounted on the bracket 108. The multiple conveying rollers 111 can transport the material frame 101 by rolling relative to the bracket 108. The rolling direction of the conveying rollers 111 is determined by the transportation direction of the material frame 101. At the battery cell incoming station, the material frame 101 is transported from the end of the conveying mechanism 109 away from the entrance 110 to the end closer to the entrance 110; at the battery cell loading station, the material frame 101 is transported from the end of the conveying mechanism 109 closer to the entrance 110 to the end farther from the entrance 110.

[0048] In an optional solution of this embodiment, the carrier platform 102 also includes a driving assembly; the driving assembly includes a conveying chain 112 and a carrying driving device 113; a conveying chain 112 is provided at at least one conveying mechanism 109, and the conveying chain 112 is engaged and connected with multiple conveying rollers 111; the carrying driving device 113 is installed on the bracket 108, and the carrying driving device 113 is connected to the conveying chain 112 to drive the conveying chain 112 to drive multiple conveying rollers 111 to roll synchronously.

[0049] In this embodiment, if Figure 3 As shown in the figure, of the two conveying mechanisms 109, the conveying mechanism 109 located at the top of the figure is an active conveying mechanism, which is provided with a conveying chain 112 that is engaged with a plurality of conveying rollers 111, and a carrying drive device 113 that is specifically an electric roller, and the electric roller is engaged with the conveying chain 112. When the electric roller rotates, the plurality of conveying rollers 111 can be driven to rotate synchronously through the conveying chain 112 to realize the transportation of the material frame 101. The other is a passive conveying mechanism, and the material frame 101 falls on the plurality of conveying rollers 111 of the passive conveying mechanism. When the material frame 101 moves under the drive of the active conveying mechanism, the plurality of conveying rollers 111 of the passive conveying mechanism are driven to roll. The plurality of conveying rollers 111 of the passive conveying mechanism can reduce the friction of transportation, ensure the synchronization of transportation on both sides of the material frame 101, and reduce one carrying drive device 113 and conveying chain 112, thereby saving more costs.

[0050] In the optional solution of this embodiment, Figures 2 to 4 As shown, the carrier 102 also includes a positioning mechanism 114; the positioning mechanism 114 includes a positioning pin 115 and a positioning drive device 116, the positioning drive device 116 is installed on the bracket 108, and the positioning drive device 116 is connected to the positioning pin 115 to drive the positioning pin 115 to extend into or exit the positioning hole of the material frame 101.

[0051] In this embodiment, for the transfer device provided at the battery cell loading station, a loading robot is provided at the end of the carrier 102 away from the inlet 110, and the loading robot is used to take out the battery cells in the material frame 101 for loading. In order to ensure the stability of the material frame 101 when the loading robot takes the material, a positioning mechanism 114 is provided on the carrier 102 to position the material frame 101. Specifically, the positioning drive device 116 is a cylinder and is provided at the end of the carrier 102 away from the inlet 110. When the material frame 101 moves to the loading robot, the positioning drive device 116 drives the positioning pin 115 to extend so that the positioning pin 115 is inserted into the positioning hole of the material frame 101 during the material taking process. Except for this process, the positioning drive device 116 drives the positioning pin 115 to retract so that the positioning pin 115 does not affect the transportation of the material frame 101.

[0052] In an optional solution of this embodiment, the carrier platform 102 also includes a position sensor; the position sensor is installed on the bracket 108 to detect the position of the material frame 101; according to the detected position of the material frame 101, the position sensor communicates with the carrier drive device 113 to control the operating status of the carrier drive device 113.

[0053] In this embodiment, the position sensor specifically includes a plurality of position switches 117 disposed on the bracket 108. According to the position of the material frame 101 detected by the position sensor, the transport drive device 113 can correspondingly execute the actions of starting, stopping, forward rotation and reverse rotation. For example, for a transfer device arranged at a battery cell loading station, an in-position switch 117 is provided at both the end of the carrier platform 102 close to the opening (the loading end of the carrier platform 102) and the end away from the opening (the unloading end of the carrier platform 102). When the material frame 101 is not placed on the loading end of the carrier platform 102, the in-position switch 117 at the loading end does not detect the material frame 101, and the transport drive device 113 is in a stopped state. When the material frame 101 is placed on the loading end of the carrier platform 102, the in-position switch 117 at the loading end detects the material frame 101, and the transport drive device 113 rotates forward to move the material frame 101 from the loading end to the unloading end. When the material frame 101 moves to the unloading end, the in-position switch 117 at the unloading end detects the material frame 101, the transport drive device 113 stops, and the positioning mechanism 114 operates to position the material frame 101. A loading robot is provided at the unloading end to take out the battery cells from the material frame 101 . When the battery cells are taken out, the transport drive device 113 is reversed to allow the empty material frame 101 to flow back, so that the transfer vehicle 103 can take away the empty material frame 101 .

[0054] In an optional solution of this embodiment, the carrier platform 102 further includes a material stopper, and at least one end of the carrier platform 102 in the transport direction is provided with a material stopper, which is installed on the bracket 108 to block and limit the material frame 101.

[0055] In this embodiment, if Figure 4 As shown, the carrier 102 further includes a first stopper 118 and a second stopper 119. First stopper 118 is a soft rubber plate located at the end of the carrier 102 away from the inlet 110. First stopper 118 is mounted on bracket 108 to block the material frame 101 as it moves toward the end, preventing it from sliding off the carrier 102 due to inertia. Once blocked by first stopper 118, positioning mechanism 114 is more easily inserted into the positioning hole of material frame 101.

[0056] A second stopper 119 is located at one end of the platform 102 near the entrance 110 and is movably mounted on the bracket 108. This stopper 119 is specifically a baffle rotatably mounted on the bracket 108 and provided with a soft rubber seal to block the material frame 101 as it moves toward this end, preventing the material frame 101 from sliding off the platform 102 due to inertia. When the transfer vehicle 103 delivers the material frame 101 to the platform 102, the first stopper 118 must rotate upward to open the entrance 110, preventing interference between the first stopper 118 and the transfer vehicle 103.

[0057] Example 2

[0058] The transfer device in this second embodiment is an improvement based on the above embodiment. The technical contents disclosed in the above embodiment will not be described repeatedly, and the contents disclosed in the above embodiment also belong to the contents disclosed in this second embodiment.

[0059] In an optional solution of this embodiment, the transfer device further includes a guide mechanism; the guide mechanism includes a vehicle stop 120 and two opposing guide members 121. The two guide members 121 are located on either side of the vehicle body 105 and extend from the parking area 104 to the outside of the entrance 110 to guide the movement of the vehicle body 105 in and out of the parking area 104. The vehicle stop 120 is located on the side of the guide member 121 away from the entrance 110, and the two ends of the vehicle stop 120 are respectively connected to the two guide members 121.

[0060] In this embodiment, if Figure 4 As shown, the guide member 121 includes a guide plate and multiple support columns connected to the guide plate to support and secure the guide plate. The guide plate includes a transition portion and a main portion. The transition portion is located at the entrance 110, and the main portion is connected to the transition portion. The main portion is located within the parking area 104. The distance between the transition portions on both sides gradually decreases as the transfer vehicle 103 enters the parking area 104, making it easier for the transfer vehicle 103 to enter the guide space formed by the two guide plates from the outside, thereby preventing the transfer vehicle 103 and the material frame 101 from colliding with the loading platform 102. The vehicle stop 120 is located on the side of the guide member 121 away from the entrance 110. When the transfer vehicle 103 is pushed into the guide space, when the transfer vehicle 103 contacts the vehicle stop 120, it indicates that the transfer vehicle 103 is in place, thereby allowing the material frame 101 to be aligned with the loading end of the loading platform 102, so that the material frame 101 can be transferred to the loading platform 102. The vehicle stopper 120 includes a vehicle stopper plate and a plurality of support columns, wherein the plurality of support columns are connected to the vehicle stopper plate to support and fix the vehicle stopper plate.
