Description

Technical Field

[0001] This utility model relates to the technical field of battery cell baking and feeding, and specifically to a battery cell feeding device. Background Technology

[0002] With the rapid development of the new energy vehicle industry, lithium batteries, as the core power source, have placed higher demands on the stability and safety of equipment during the cell baking process. Before baking, the cells need to be accurately conveyed and limited by the feeding equipment to avoid material deformation or performance damage. Currently, the industry generally uses mechanical push rods or belt conveyors.

[0003] However, existing push rod or belt transmission methods have the following drawbacks: 1. They usually use a single limiting structure for limiting. During the battery cell transportation process, the single limiting structure cannot provide bidirectional constraint due to equipment vibration or tilt, which may lead to displacement or even drop of the battery cell; 2. The rigid contact of the mechanical push rod or the friction of the belt can easily scratch the battery cell coating, and uneven extrusion force can easily cause deformation of the internal structure of the battery cell; 3. The equipment height adjustment depends on manual operation and cannot quickly match the inlet position of different baking equipment. Utility Model Content

[0004] This utility model addresses the aforementioned problems and aims to provide a battery cell feeding device that offers good stability during battery cell transport, reduces wear on the battery cells, and has a high degree of automation.

[0005] To achieve the above objectives, this utility model provides a battery cell feeding device, comprising:

[0006] The positioning mechanism includes a placement frame and a first limiting plate. The placement frame is provided with a receiving groove for accommodating the battery cell. One end of the receiving groove is provided with a first opening. The first limiting plate is detachably installed at the first opening of the receiving groove and can cooperate with the side wall of the receiving groove to clamp the battery cell.

[0007] A lifting mechanism configured to drive the placement rack to perform lifting movements;

[0008] A pushing mechanism configured to drive the battery cell located in the receiving slot out of the placement rack from the first opening of the receiving slot.

[0009] According to the above-described battery cell feeding device, the bottom of the first limiting plate is rotatably mounted on one end of the placement frame via an adapter plate. When the first limiting plate rotates to block the first opening, one side of the first limiting plate is connected to the placement frame via a first bolt.

[0010] According to the above-described battery cell feeding device, the positioning mechanism further includes a slide, which is arranged in the receiving groove and close to the first opening. The slide includes a frame and a plurality of pulleys, which are rotatably installed in the frame along the arrangement direction of the first opening. The battery cell can abut against the pulleys.

[0011] According to the above-described battery cell feeding device, the pushing mechanism includes a first power unit and an inclined plate. The inclined plate is located in the receiving groove, and one side of the inclined plate is rotatably hinged to the end of the frame away from the first opening via a rotating shaft. The output shaft of the first power unit is connected to the inclined plate.

[0012] According to the above-described battery cell feeding equipment, the pushing mechanism further includes a mounting plate and a connecting plate. The first power unit is an air pump. The mounting plate is detachably mounted to the placement frame by a second bolt. The connecting plate is connected to the bottom of the inclined plate. The air pump is fixed on the mounting plate, and the output shaft of the air pump passes through the mounting plate and the placement frame in sequence, and is connected to the connecting plate.

[0013] According to the above-described battery cell feeding device, the bottom of the inclined plate is provided with a guide groove, and the connecting plate is slidably arranged in the guide groove.

[0014] According to the above-described battery cell feeding device, the placement rack is further provided with a second limiting plate, and the other end of the receiving groove is provided with a second opening. The second limiting plate is installed at the second opening, and the first limiting plate can cooperate with the second limiting plate to clamp both ends of the battery cell.

[0015] According to the above-described battery cell loading equipment, the lifting mechanism includes a second power unit and a scissor lift frame, the placement frame is installed on the top of the scissor lift frame, and the second power unit is used to provide power to the scissor lift frame.

[0016] According to the above-described battery cell feeding equipment, the lifting mechanism further includes a support frame, the bottom of which is provided with multiple casters, and the scissor lift is mounted on the support frame.

[0017] According to the above-described battery cell feeding equipment, the lifting mechanism further includes a control cabinet, which is mounted on the support frame. The second power unit includes a hydraulic cylinder, and the control cabinet is used to control the hydraulic cylinder.

[0018] This utility model has the following beneficial effects:

[0019] 1. A detachable first limiting plate is provided on the placement rack. When the battery cell is placed into the receiving slot, the first limiting plate can be fixedly connected to the placement rack by the first bolt. The cooperation between the first limiting plate and the receiving slot can clamp the battery cell and ensure the stability of the battery cell during the lifting process. After the movement is in place, the first limiting plate can be unlocked, thereby opening the first opening of the receiving slot, so that the battery cell can move from the first outlet into the baking equipment. This can effectively prevent the battery cell from shifting during the lifting process and reduce the risk of battery cell damage caused by shaking.

[0020] 2. An air pump can drive an inclined plate to provide tilting force to the battery cell, and a pulley can provide sliding support for the battery cell. When the battery cell is subjected to tilting force, it can roll out of the receiving groove through the pulley, which can avoid squeezing the battery cell. At the same time, rolling friction is used instead of the traditional push rod squeezing method, which significantly reduces mechanical friction damage to the surface of the battery cell.

[0021] 3. The lifting and lowering action of the hydraulic cylinder can be controlled through the control cabinet. It can be automatically controlled according to the height of the baking equipment without manual intervention. Attached Figure Description

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figure 1-4 As shown, a battery cell loading device includes a positioning mechanism 100, a lifting mechanism 200, and a pushing mechanism 300. The positioning mechanism 100 is used to position the battery cell, the lifting mechanism 200 is used to drive the positioning mechanism 100 to a position at the same height as the opening of the baking device, and the pushing mechanism 300 is used to push the battery cell out of the positioning mechanism 100 and move it into the opening of the baking device.

[0032] Specifically, the positioning mechanism 100 includes a placement rack 110 and a first limiting plate 120. The placement rack 110 has a receiving groove 111 for accommodating the battery cell. One end of the receiving groove 111 has a first opening 111a. The first limiting plate 120 is detachably installed at the first opening 111a of the receiving groove 111 and can cooperate with the side wall of the receiving groove 111 to clamp the battery cell. The first opening 111a of the receiving groove 111 faces the opening of the baking equipment. The battery cell needs to be moved out of the placement rack 110 from the first opening 111a. In this embodiment, when the battery cell is placed into the receiving groove 111, the first limiting plate 120 can be moved out of the receiving rack 110. The battery cell is installed at the first opening 111a of the receiving groove 111. The first limiting plate 120 is used to clamp and position the battery cell by cooperating with the receiving groove 111. Then, the positioning mechanism 100 is driven to rise by the lifting mechanism 200. During this process, since the battery cell has been completely positioned, it will not shake during the lifting and lowering process with the positioning mechanism 100, thus avoiding damage to the battery cell caused by shaking. After the lifting and lowering is in place, the first limiting plate 120 can be disassembled to contact its locked state. Thus, under the action of the pushing mechanism 300, the battery cell can be separated from the receiving groove 111 and the placement rack 110 from the first opening 111a.

[0033] Furthermore, in this embodiment, to avoid the first limiting plate 120 being lost due to frequent disassembly, the bottom of the first limiting plate 120 is rotatably mounted on one end of the placement rack 110 via an adapter plate 121. When the first limiting plate 120 rotates to block the first opening 111a, one side of the first limiting plate 120 is connected to the placement rack 110 via a first bolt 122. When the first limiting plate 120 is connected to the placement rack 110 via the first bolt 122, the first limiting plate 120 cannot rotate, and it plays the role of positioning the battery cell in conjunction with the receiving groove 111. When the first bolt 122 is removed, the first limiting plate 120 can rotate via the adapter plate 121, thereby opening the first opening 111a to allow the battery cell to exit from the first opening 111a.

[0034] Furthermore, the positioning mechanism 100 also includes a carriage 130, which is arranged in the receiving groove 111 and close to the first opening 111a. The carriage 130 includes a frame 131 and a plurality of pulleys 132. The plurality of pulleys 132 are rotatably mounted in the frame 131 along the arrangement direction of the first opening 111a. The battery cell can abut against the pulleys 132. That is, the plurality of pulleys 132 can provide rolling support for the battery cell, reduce the friction of the battery cell during the driving process of the pushing mechanism 300, and reduce the friction of the battery cell, thereby reducing the surface damage of the battery cell caused by mechanical friction.

[0035] Of course, in this embodiment, the multiple pulleys 132 are arranged in the direction of the first opening 111a, so as to guide the battery cell to the first opening 111a and facilitate the movement of the battery cell.

[0036] Specifically, the pushing mechanism 300 is configured to drive the battery cell located in the receiving groove 111 to detach from the placement frame 110 from the first opening 111a of the receiving groove 111. The pushing mechanism 300 includes a first power unit and an inclined plate 320. The inclined plate 320 is located in the receiving groove 111, and one side of the inclined plate 320 is rotatably hinged to the end of the frame 131 away from the first opening 111a via a rotating shaft. The output shaft of the first power unit is connected to the inclined plate 320. When the output shaft of the first power unit rises, it can drive the inclined plate 320 to rotate around its hinge point. During the rotation of the inclined plate 320, it can drive the end of the battery cell away from the first opening 111a to rise, thereby giving the battery cell an inclined force, so that it can move towards the side closer to the first opening 111a. With the help of the pulley 132, the battery cell can be guided to make directional displacement, and there is no need to drive the battery cell by squeezing, thus avoiding damage to the battery cell structure caused by squeezing the battery cell.

[0037] Furthermore, in order to realize the installation of the first power unit and the driving of the tilting plate 320, the pushing mechanism 300 also includes a mounting plate 330 and a connecting plate 340. The first power unit is an air pump 310. In this embodiment, the mounting plate 330 is detachably installed below the placement frame 110 by the second bolt 331. The connecting plate 340 is connected to the bottom of the tilting plate 320. The air pump 310 is fixed on the mounting plate 330, and the output shaft of the air pump 310 passes through the mounting plate 330 and the placement frame 110 in sequence and is connected to the connecting plate 340. Since the rotational accuracy requirement of the tilting plate 320 is not high, the driving requirement can be met by using the air pump 310, which has lower accuracy, which can effectively reduce costs. The mounting plate 330 can realize the installation and positioning of the air pump 310, and the connecting plate 340 can realize the connection between the output shaft of the air pump 310 and the tilting plate 320.

[0038] Furthermore, in order to enable the lifting and lowering motion of the output shaft of the air pump 310 to drive the tilting plate 320 to rotate, a guide groove 321 is provided at the bottom of the tilting plate 320. The connecting plate 340 is slidably arranged in the guide groove 321. During the rotation of the tilting plate 320, the connecting plate 340 can slide in the guide groove 321, thereby adjusting the relative position of the connecting plate 340 and the tilting plate 320, ensuring that the connecting plate 340 can always move in the up and down direction. Of course, the connecting plate 340 should be locked in the guide groove 321 to prevent the connecting plate 340 from detaching from the tilting plate 320.

[0039] In another preferred embodiment, the pushing mechanism can also be a translation cylinder, which can directly drive the battery cell to roll on multiple pulleys, thus achieving the same driving mechanism for the battery cell.

[0040] Furthermore, the placement rack 110 is also provided with a second limiting plate 112, and the other end of the receiving groove 111 is provided with a second opening 111b. The second limiting plate 112 is installed at the second opening 111b. The first limiting plate 120 can cooperate with the second limiting plate 112 to clamp the two ends of the battery cell, clamping the front and rear ends of the battery cell to prevent the battery cell from shaking due to vibration. The second limiting plate 112 can be fixed to the second opening 111b of the receiving groove 111 in a detachable manner, or it can be fixed to the second opening 111b of the receiving groove 111 in a non-detachable manner, such as by welding or other means. The second opening 111b does not need to pass through the battery cell.

[0041] Specifically, the lifting mechanism 200 is configured to drive the placement frame 110 to perform lifting movements. The lifting mechanism 200 includes a second power unit and a scissor lift frame 220. The placement frame 110 is installed on the top of the scissor lift frame 220, and the second power unit is used to provide power to the scissor lift frame 220 so that it can move up and down. The scissor lift frame 220 is a commonly used lifting structure. Because its structure is similar to scissors, it is called a scissor lift frame 220. It has the characteristic of good lifting stability. Therefore, when driving the placement frame 110 and the battery cell to rise, it can effectively improve the stability of the battery cell's rise.

[0042] Furthermore, the lifting mechanism 200 also includes a support frame 230. The bottom of the support frame 230 is provided with multiple casters 231. The scissor lift frame 220 is mounted on the support frame 230. The support frame 230 is used to provide rolling support for the lifting frame and the placement rack 110, so as to drive the lifting frame and the placement rack 110 to a suitable position, that is, close to the baking equipment. In this embodiment, the upper bracket and the lower bracket on the same side of the scissor lift frame 220 are slidably connected to the placement rack 110 and the support frame 230, respectively. That is, the sides of the placement rack 110 and the support frame 230 are provided with sliding grooves. One end of the upper bracket and the lower bracket are slidably set in the two sliding grooves to meet the lifting conditions of the scissor lift frame 220.

[0043] Furthermore, the lifting mechanism 200 also includes a control cabinet 240 and a handle 250. The control cabinet 240 is mounted on the support frame 230. The second power unit includes a hydraulic cylinder 210, and the control cabinet 240 is used to control the hydraulic cylinder 210 to perform its actions. Since the lifting height of the placement rack 110 needs to be consistent with the opening height of the baking equipment, its lifting requires high precision. Therefore, the second power unit uses a hydraulic cylinder 210, which has high precision and moderate cost. Of course, in addition to the hydraulic cylinder 210, high-precision drive components such as motors can also be used. By controlling the hydraulic cylinder 210 to perform lifting actions through the control cabinet 240, the lifting height can be automatically controlled without manual operation, and can quickly match the entrance of the baking equipment. The handle 250 is located on the outside of the control cabinet 240, and both ends of the handle 250 are connected to the support frame 230. The operator can use the handle 250 to control the support frame 230 to move in the corresponding direction.

[0044] In this embodiment, a battery cell loading device is disclosed, including a positioning mechanism 100, a lifting mechanism 200, and a pushing mechanism 300. The positioning mechanism 100 includes a placement frame 110 and a first limiting plate 120. The placement frame 110 is provided with a receiving groove 111 for receiving battery cells. One end of the receiving groove 111 is provided with a first opening 111a. The first limiting plate 120 is detachably installed at the first opening 111a of the receiving groove 111 and can cooperate with the side wall of the receiving groove 111 to clamp the battery cells. The lifting mechanism 200 is configured to drive the placement frame 110 to perform lifting and lowering movements. The pushing mechanism 300 is configured to drive the placement frame 110 to perform lifting and lowering movements. The battery cell in the slot 111 detaches from the placement rack 110 from the first opening 111a of the slot 111. When the battery cell is placed into the slot 111, the first limiting plate 120 can be fixedly connected to the placement rack 110 by the first bolt 122. The battery cell can be clamped by the cooperation between the first limiting plate 120 and the slot 111. After the movement is in place, the first limiting plate 120 can be unlocked, thereby opening the first opening 111a of the slot 111, which makes it easier for the battery cell to move from the first outlet into the baking equipment. This can effectively prevent the battery cell from shifting during the lifting process and reduce the risk of battery cell damage caused by shaking.
