Description

Technical Field

[0001] This invention relates to the field of current collector receiving technology, specifically a receiving device for a positive current collector. Background Technology

[0002] With the rapid development of the new energy lithium battery industry, the positive electrode current collector, as a core conductive connector of the battery, directly affects the battery assembly quality and performance due to its mass production processing precision and neatness of storage. After mass production, lithium battery positive electrode current collectors need to be collected and stored uniformly.

[0003] However, conventional receiving equipment can only receive materials at a single fixed point. After the receiving is full, the machine needs to be stopped to unload and change the frame, resulting in poor production continuity and severely restricting the overall cycle time of the production line. At the same time, the existing receiving structure cannot adapt to changes in the stacking height of materials. The drop height increases continuously with the increase in the stacking amount, which can easily cause deformation of the collecting plate and surface damage. Summary of the Invention

[0004] The purpose of this invention is to provide a receiving device for a positive current collector to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a receiving device for a positive electrode current collector, comprising a receiving frame and a laser displacement sensor. A mounting plate is provided on one side of the top of the receiving frame, and a connecting plate is mounted on the outer surface of the mounting plate. The laser displacement sensor is located at the end of the connecting plate, and an adjustment component for assisting height adjustment is installed below the laser displacement sensor. The adjustment component includes a fixing plate, a combination plate, an outer threaded sleeve, and an inner threaded rod. The combination plate is engaged and fixed at the top of the fixing plate. An outer threaded sleeve is installed at the bottom of the fixing plate, and an inner threaded rod is provided within the inner threaded sleeve. A drive component for providing driving force is installed at the bottom of the inner threaded rod. The drive component includes a servo motor, a drive roller, a synchronous belt, and a transmission roller. The output end of the servo motor is equipped with a drive roller, and a transmission roller is mounted on the outer surface of the drive roller via a synchronous belt drive.

[0006] Furthermore, the center of the transmission roller is perpendicular to the inner screw, and the inner screw and the transmission roller are distributed in a one-to-one correspondence.

[0007] Furthermore, a collection plate is provided on one side of the receiving frame one, and a receiving frame two is installed on one side of the collection plate.

[0008] Furthermore, the receiving frame one and receiving frame two have the same structure, and support plates are installed on both sides of the bottom of the collecting plate.

[0009] Furthermore, the support plate is provided in two sets, and a connecting plate is integrally installed between the two sets of support plates.

[0010] Furthermore, a drive motor is installed at the bottom of the connecting plate, and a motor frame is provided outside the drive motor.

[0011] Furthermore, the motor frame has a hollow structure, and a sliding base is provided at the bottom of the motor frame.

[0012] Furthermore, a movable frame is provided on the outside of the slide block, and a servo motor II is installed on one side of the movable frame. A lead screw is provided at the output end of the servo motor II, and the slide block is threadedly connected to the lead screw. Assembly plates are provided on the outer surfaces of both sides of the movable frame.

[0013] Furthermore, it also includes a controller, which is electrically connected to the laser displacement sensor, the first servo motor, and the second servo motor. Furthermore, the inner wall of the outer threaded sleeve and the outer wall of the inner threaded rod are both provided with mating threads, and the outer threaded sleeve and the fixing plate are connected in a non-rotatable manner; the outer threaded sleeve and the fixing plate are either integrally formed or have a keyway fixed connection structure.

[0014] This invention provides a receiving device for a positive current collector, which has the following advantages: 1. This invention achieves adaptive constant height compensation for receiving material through the coordinated linkage of a laser displacement sensor, adjustment component, and drive component. This effectively improves the stability of positive electrode collector stacking and reduces material damage. The laser displacement sensor detects the stacking height of the collectors in the receiving frame in real time. After feeding the height signal back to the controller, the servo motor of the drive component is activated. This drives the transmission roller through the active roller and synchronous belt, which in turn drives the inner screw and outer screw sleeve to engage in threaded transmission, thereby raising and lowering the entire adjustment component. This compensates for the height increase caused by material stacking in real time. At the same time, the assemblable design of the fixed plate and the combination plate in the adjustment component allows the initial receiving height to be pre-adjusted according to the production cycle, adapting to different working conditions. This linkage mechanism always maintains a constant receiving port height, avoiding material collisions caused by excessive drop height, ensuring orderly stacking of the collectors, reducing product loss, and guaranteeing receiving quality.

[0015] 2. This invention achieves uninterrupted automated material receiving by relying on the coordinated operation of dual receiving modules and horizontal movement and rotational positioning mechanisms, significantly improving production efficiency and equipment automation levels. Servo motor two drives the lead screw and slide screw transmission, causing the assembly plate and receiving frames one and two to move horizontally as a whole, ensuring precise alignment of the receiving module with the upstream discharge port and accurate positioning of the receiving position. When one set of receiving frames is fully loaded, servo motor two reverses the drive module to retract and avoid rotational interference. Subsequently, the drive motor drives the assembly plate to rotate as a whole through the connecting plate, achieving a switch between the fully loaded and empty modules. After the switch, the empty module again precisely aligns and receives material through horizontal movement, while the fully loaded module unloads and resets at the designated position. This linkage mechanism of dual module rotation, horizontal alignment, and rotational positioning eliminates the process interval between receiving and unloading, achieving uninterrupted cyclical material receiving and reducing manual intervention.

Detailed Implementation

[0018] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0019] like Figures 1-6 As shown, a receiving device for a positive electrode current collector includes a receiving frame 1, a receiving frame 2, a collecting plate 3, a mounting plate 4, a connecting plate 5, a laser displacement sensor 6, an adjusting assembly 7, a fixing plate 701, a combination plate 702, an external threaded sleeve 703, an internal screw 704, a drive assembly 8, a servo motor 1 801, a drive roller 802, a synchronous belt 803, a transmission roller 804, a support plate 9, a connecting plate 10, an assembly plate 11, a drive motor 12, a motor frame 13, a slide block 14, a moving frame 15, a servo motor 2 16, and a lead screw 17. A mounting plate 4 is provided on one side of the top of the receiving frame 1, and a connecting plate 5 is mounted on the outer surface of the mounting plate 4. A collecting plate is provided on one side of the receiving frame 1. 3. A receiving frame 2 is installed on one side of the collecting plate 3. The receiving frame 1 and receiving frame 2 have the same structure. Support plates 9 are installed on both sides of the bottom of the collecting plate 3. A laser displacement sensor 6 is located at the end of the connecting plate 5. An adjustment component 7 for assisting height adjustment is installed below the laser displacement sensor 6. The adjustment component 7 includes a fixing plate 701, a combination plate 702, an outer threaded sleeve 703, and an inner threaded rod 704. The combination plate 702 is fixedly engaged at the top of the fixing plate 701. The outer threaded sleeve 703 is installed at the bottom of the fixing plate 701. The inner threaded rod 704 is provided inside the outer threaded sleeve 703. A drive component 8 for providing driving force is installed at the bottom of the inner threaded rod 704. Drive assembly 8 includes a servo motor 801, a drive roller 802, a synchronous belt 803, and a transmission roller 804. The drive roller 802 is mounted on the output end of the servo motor 801, and the transmission roller 804 is mounted on the outer surface of the drive roller 802 via the synchronous belt 803. The middle part of the transmission roller 804 is perpendicular to the inner screw 704, and the inner screw 704 and the transmission roller 804 are distributed in a one-to-one correspondence. A mounting plate 4 is fixed on the outer side of the receiving frame 1. The mounting plate 4 is equipped with a laser displacement sensor 6 via a connecting plate 5. The adjustment assembly 7 consists of a fixed plate 701, a combination plate 702, an outer screw sleeve 703, and an inner screw 704. Drive assembly 8 includes a servo motor 801, a drive roller 802, a synchronous belt 803, and a transmission roller 804. The stepping belt 803, transmission roller 804, and laser displacement sensor 6 detect the height of the upper surface of the positive collector stacked in the receiving frame in real time. The servo motor 801 drives the active roller 802 to rotate, which drives the transmission roller 804 through the synchronous belt 803 to rotate the inner screw 704. The inner screw 704 and the outer screw sleeve 703 are threaded together to drive the transmission, which drives the fixed plate 701 in the receiving frame to adjust the height of the receiving frame in real time. The surface of the fixed plate 701 can be assembled with the combination plate 702, which makes it easy to pre-adjust the initial height of the fixed plate 701 when receiving materials according to the required frequency. This achieves adaptive lifting compensation, continuously maintains a constant receiving height, ensures stable stacking of materials, and reduces damage to objects caused by gravity.

[0020] like Figure 1 and Figure 6As shown, there are two sets of support plates 9, and a connecting plate 10 is integrally installed between the two sets of support plates 9. A drive motor 12 is installed at the bottom of the connecting plate 10, and a motor frame 13 is provided outside the drive motor 12. The motor frame 13 has a hollow structure, and a slide block 14 is provided at the bottom of the motor frame 13. A moving frame 15 is provided outside the slide block 14, and a servo motor 16 is installed on one side of the moving frame 15. A lead screw 17 is provided at the output end of the servo motor 16, and the slide block 14 is threadedly connected to the lead screw 17. Assembly plates 11 are provided on the outer surfaces of both sides of the moving frame 15. The servo motor 16 drives the lead screw 17 to rotate, and the lead screw 17 is threadedly driven to the slide block 14. The slide block 14 and the moving frame 15 form a horizontal guide structure, which drives the collecting plate 3 and the receiving frame 1 and receiving frame 2 to move horizontally as a whole, so that the receiving module receiving frame 1 and receiving frame 2 to be received is accurately moved to the receiving position below the upstream outlet. The device completes precise alignment of two receiving positions. When one set of receiving frames is full, servo motor 16 drives screw 17 in the reverse direction, causing the entire module to move backward to avoid interference. The bottom of the connecting plate 10 is fixedly mounted with drive motor 12 through motor frame 13. Drive motor 12 outputs power to drive the collection plate 3 to rotate as a whole, rotating and switching the full receiving frame 1 or receiving frame 2 to the unloading position. At the same time, the other empty receiving module is rotated and switched to the receiving area. After the rotation is in place, the empty receiving module is again aligned horizontally forward by servo motor 16 and screw 17 to continue receiving materials. The full receiving frame at the unloading position is unloaded and emptied, waiting for the next station rotation. The device completes the automated receiving operation of the positive collector plate through the reciprocating switching of receiving frame 1 and receiving frame 2, combined with the coordinated actions of horizontal movement alignment, constant height receiving adjustment, and rotational unloading.

[0021] In summary, the receiving device of this positive current collector firstly... Figures 1-6The structure shown is as follows: In use, the receiving frame 1 and receiving frame 2 are identical in structure and are uniformly assembled on the collecting plate 3. Support plates 9 are fixed to both sides of the bottom of the collecting plate 3. A connecting plate 10 is integrally connected between the two sets of support plates 9, forming an overall load-bearing frame with the assembly plate 11, ensuring the overall structural strength and operational stability of the equipment. The moving frame 15 is fixed in place by the assembly plates 11 installed on both sides. A servo motor 2 16 is installed on the outside of the moving frame 15, and the output end of the servo motor 2 16 is connected to a lead screw 17. The slide 14 and the lead screw 17 form a threaded transmission pair. The slide 14 is externally confined within the moving frame 15, relying on the moving frame 15 for support. In linear guidance, during operation, servo motor 16 drives screw 17 to rotate, causing slide 14, upper collecting plate 3, receiving frame 1, and receiving frame 2 to move horizontally as a whole. This allows the two receiving modules to precisely approach or move away from the upstream discharge end, achieving precise alignment of the two receiving positions and meeting the requirement for accurate material receiving and dropping. A mounting plate 4 is fixed to one side of the top of receiving frame 1, and a connecting plate 5 is fixed to the outer surface of mounting plate 4. A laser displacement sensor 6 is installed at the end of connecting plate 5. The laser displacement sensor 6 can vertically and downwardly detect the height of the upper surface of the stacked positive current collector inside the receiving frame in real time. The monitored height can be used to control servo motor 1 through the controller. The operation of 801 involves an adjustment component 7 located below the laser displacement sensor 6. The adjustment component 7 consists of a fixed plate 701, a combined plate 702, an outer threaded sleeve 703, and an inner screw 704. The top of the fixed plate 701 engages with and fixes the combined plate 702, facilitating pre-adjustment of the initial installation height of the fixed plate 701 according to the production cycle, adapting to different material receiving conditions. The bottom of the fixed plate 701 is fitted with the outer threaded sleeve 703, whose internal thread engages with the inner screw 704. The bottom end of the inner screw 704 is connected to the drive component 8, which includes a servo motor 801, a drive roller 802, a synchronous belt 803, and a transmission roller 804. Servo motor 801 drives the active roller 802 to rotate, which in turn drives the transmission roller 804 to rotate synchronously via synchronous belt 803. The transmission roller 804 corresponds to the inner screw 704 and is arranged vertically, thereby driving the outer screw sleeve 703 to rotate and rise outside the inner screw 704. As the material is continuously stacked, the laser displacement sensor 6 provides real-time feedback of height change signals, which in turn controls the start, stop and turn of the servo motor 801. Through the threaded transmission, the adjustment component 7 is driven to finely adjust the overall height, compensate for the material stacking increment in real time, and always keep the height of the receiving port constant, avoid excessive drop difference, reduce material collision damage, and ensure that the collecting plate is stacked smoothly and orderly. The bottom of the connecting plate 10 is fixedly mounted with a drive motor 12 via a hollowed-out motor frame 13. The drive motor 12 provides rotational power for station switching. When the positive collector plate inside the receiving frame 1 or receiving frame 2 is full, the servo motor 2 16 drives the lead screw 17 in the reverse direction, causing the upper module to retract backward, effectively avoiding rotational interference. Then, the drive motor 12 starts, driving the collecting plate 3 to rotate as a whole, rotating the fully loaded receiving frame to the unloading station, while simultaneously rotating the other empty receiving frame to the receiving area, thus completing the station switching. After completion, the empty receiving module is driven forward again by servo motor 16 and lead screw 17 to accurately align with the upstream discharge port for continuous material receiving. After the full receiving frame at the unloading station is unloaded and emptied, it is reset to wait for the next rotation. The device relies on the alternating cooperation of receiving frame 1 and receiving frame 2, combined with the horizontal movement and alignment of the module driven by servo motor 16, the constant height receiving adjustment in cooperation with laser displacement sensor 6 and adjustment component 7, and the rotational unloading driven by drive motor 12 to achieve uninterrupted cyclic material receiving, which greatly improves the automation level and production efficiency of the equipment.
