Description

A split-type sheet feeder Technical Field

[0001] This invention relates to the field of sheet feeder technology, and more particularly to a split-type sheet feeder. Background Technology

[0002] A feeder, also known as a material feeder or feeder, is primarily used to supply materials to a pick-and-place machine for placement. The materials supplied by the feeder are typically adhered to a soft, smooth backing paper and wound up to form a tape for transport and storage.

[0003] Traditional sheet feeders integrate the hopper, stripping, picking, and positioning mechanisms along a single axis, resulting in a long, narrow layout. In new energy vehicle manufacturing, key sheet materials such as positive electrode sheets, negative electrode sheets, and separators for power batteries require high-speed continuous feeding without damage to the electrode edges. The spacing between workstations on power battery module assembly lines is small, and the lateral dimensions of traditional feeders exceed this spacing, preventing multiple machines from being arranged in parallel and forcing them to be arranged serially. This extends the production line length, leading to a large space occupation and low space utilization. Therefore, a split sheet feeder is proposed to solve these problems. Summary of the Invention

[0004] To overcome the above shortcomings, the present invention provides a split sheet feeder, which aims to improve the problems of the existing sheet feeder, which has a "long strip" layout with the material bin, stripping, picking and positioning mechanism integrated along a single axis. The horizontal dimension exceeds the spacing between workstations in the power battery module assembly line, which means that multiple devices cannot be arranged in parallel and can only be arranged in series, thus extending the production line length, occupying a large space and having low space utilization.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a split-type sheet feeder, comprising a frame, a hopper feeding mechanism for feeding material is provided on the outer wall of the frame, a feeding mechanism is provided above the hopper feeding mechanism, a transmission mechanism, a pressing mechanism and a support mechanism are provided on the frame, and a stripping plate is installed on the frame. The hopper feeding mechanism includes: a hopper frame, which is detachably connected to the side wall of the frame, and a limit plate is fixedly connected to the hopper frame; a lifting platform, which is slidably connected to the limit plate and driven by a lifting assembly; and a mounting plate, which is fixedly installed on the hopper frame by bolts, and a guide rail is fixedly connected to the mounting plate. The guide rail is slidably connected to the lifting platform, and a gear is driven to rotate by the output shaft of a stepper motor. Under the action of the rack, the limit plate and the guide rail, the lifting platform can be stably lifted and lowered to achieve feeding.

[0006] As a further description of the above technical solution: the lifting assembly includes a stepper motor, a gear, and a rack. The stepper motor is fixedly installed at the bottom of the lifting platform. The output shaft of the stepper motor is fixedly connected to the gear, and the gear meshes with the rack.

[0007] As a further description of the above technical solution: the feeding mechanism includes a connecting frame, a transverse drive assembly, a cylinder, a connecting plate, a mounting component, and a suction cup clamp. The connecting frame is detachably connected to the hopper frame. The transverse drive assembly is mounted on the connecting frame and is used to drive the cylinder to move transversely. The connecting plate is fixedly connected to the output end of the cylinder and is fixedly connected to the mounting component. The suction cup clamp is mounted on the mounting component. By driving the connecting plate to rise and fall through the output end of the cylinder, the mounting component can drive the suction cup clamp to clamp the material. Furthermore, by using the transverse drive assembly, the material can be placed on the breathable membrane.

[0008] As a further description of the above technical solution: the suction cup clamp is provided in multiple sets, and the multiple sets of suction cup clamps can be detachably installed on the mounting part by bolts, and the position of the suction cup clamp is adjustable, so as to facilitate the adjustment of the position of the suction cup clamp according to different sized materials.

[0009] As a further description of the above technical solution: the transmission mechanism includes an output roller, a transmission roller and a pressure roller. The output roller is driven by a motor. The transmission roller is rotatably connected to the inner surface of the frame. The pressure roller is rotatably connected to the frame. The output roller, transmission roller and pressure roller are all driven by breathable membranes. The output roller is driven by a motor, so that the breathable membranes are driven on it.

[0010] As a further description of the above technical solution: the pressing mechanism includes a support frame 1, a placement plate 1, a cylinder 2, a crossbeam and a pressing block. The placement plate 1 is fixedly connected to the support frame 1, the cylinder 2 is fixedly installed on the support frame 1, the crossbeam is fixedly connected to the output end of the cylinder 2, and the pressing block is installed on the crossbeam. The output end of the cylinder 2 drives the crossbeam and the pressing block to descend, which can press the material, making it easier to peel off the material later.

[0011] As a further description of the above technical solution: the bottom of the pressure roller is flush with the upper side of the placement plate, so that the breathable membrane is attached to the placement plate and moves in this way.

[0012] As a further description of the above technical solution: the cross frame is provided with mounting holes, and the pressure block is adjusted in position on the cross frame through the mounting holes. In this way, materials of different sizes can be pressed.

[0013] As a further description of the above technical solution: the placement plate has a through hole, and the through hole is connected to the connection port. In this way, a negative pressure can be formed at the through hole to suck up the material on the breathable membrane.

[0014] As a further description of the above technical solution: the support mechanism includes a second support frame, a second placement plate, a second stepper motor, a second gear, a second rack, a mounting base, and a second guide rail. The second support frame is slidably connected to the second guide rail, and the second guide rail is fixedly connected to the frame. The second placement plate is fixedly connected to the second support frame. The second stepper motor is fixedly mounted on the second support frame. The second gear is fixedly connected to the output shaft of the second stepper motor. The second gear meshes with the second rack. The second rack is fixedly mounted on the mounting base, and the mounting base is fixedly connected to the frame. By starting the second stepper motor, the second gear is driven to rotate. Under the action of the second rack and the second guide rail, the second support frame and the second placement plate move, thereby maintaining support for the material during material stripping. The second placement plate is flush with the first placement plate.

[0015] The present invention has the following beneficial effects: 1. In the present invention, by adopting a split structure design, the material feeding mechanism of the hopper can be detachably installed on the side wall of the frame, and the feeding, transmission, and pressing mechanisms are modularly distributed, which greatly reduces the horizontal size of the equipment, adapts to the narrow workstation spacing of the power battery module assembly line, and allows multiple machines to be arranged in parallel without the need for a serial arrangement, effectively shortening the overall length of the production line, reducing the factory space occupancy rate, improving space utilization, simplifying the structure, and reducing the cost per machine.

[0016] 2. In this invention, the coordinated operation of multiple modules, including the hopper feeding mechanism, the conveying mechanism, and the transmission mechanism, ensures continuous feeding of sheet materials without edge damage. The stepper motor of the hopper feeding mechanism drives the lifting platform to rise and fall stably, achieving precise feeding of the material belt. The multiple adjustable suction cup clamps of the conveying mechanism can be flexibly adjusted according to the material size, avoiding damage to the electrode edges during clamping. The position of the pressing block of the pressing mechanism can be adjusted through the mounting holes, and in conjunction with the negative pressure adsorption function of the placement plate, it ensures that the material fits flatly against the breathable membrane, without deviation or wrinkles during transmission. The placement plate of the support mechanism moves synchronously, providing stable support for the material during the peeling process, preventing deformation of the material due to uneven force, and ensuring stable feeding.

[0017] 3. In this invention, components such as the hopper frame and connecting frame are connected to the machine frame with bolts, eliminating the need for complex tools during disassembly and assembly. Key components such as the lifting platform of the hopper feeding mechanism and the suction cup clamps of the feeding mechanism can be disassembled, repaired, or replaced individually. When a module malfunctions, there is no need to stop the machine and disassemble the entire machine, effectively shortening maintenance time and reducing production line downtime losses. Simultaneously, the positions of vulnerable parts such as suction cup clamps and pressure blocks can be flexibly adjusted to accommodate different specifications of positive electrode sheets, negative electrode sheets, separator membranes, and other materials, eliminating the need for dedicated equipment for different materials and reducing equipment procurement and replacement costs.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Referring to Figures 1-3, one embodiment of the present invention provides a split-type sheet feeder, including a frame 1. A hopper feeding mechanism 2 for feeding materials is provided on the outer wall of the frame 1. A feeding mechanism 3 is provided above the hopper feeding mechanism 2. A transmission mechanism 4, a pressing mechanism 5, and a support mechanism 6 are provided on the frame 1. A stripping plate 7 is installed on the frame 1. A height adjustment component (not shown in the figure) is provided at the bottom of the stripping plate 7. The height adjustment component is an existing adjustment component, used to adjust the height of the stripping plate 7 during subsequent stripping to achieve stripping of different materials.

[0022] The material feeding mechanism 2 includes a hopper frame 21, a lifting platform 22, and a mounting plate 28. The hopper frame 21 is detachably connected to the side wall of the frame 1. A limit plate 26 is fixedly connected to the hopper frame 21. The lifting platform 22 is slidably connected to the limit plate 26 and is driven by a lifting assembly. The mounting plate 28 is fixedly installed on the hopper frame 21 with bolts. A guide rail 27 is fixedly connected to the mounting plate 28 and is slidably connected to the lifting platform 22. The lifting assembly includes a stepper motor 23, a gear 24, and a rack 25. The stepper motor 23 is fixedly installed at the bottom of the lifting platform 22. The output shaft of motor 23 is fixedly connected to gear 24, and gear 24 meshes with rack 25. The output shaft of stepper motor 23 drives gear 24 to rotate. Under the action of rack 25, limit plate 26 and guide rail 27, the lifting platform 22 is lifted stably to achieve material feeding. At the same time, the detachable modular design of hopper frame 21 can facilitate the assembly and disassembly of hopper feeding mechanism 2, reduce the horizontal size of the equipment, adapt to the narrow workstation spacing of power battery module assembly line, shorten the overall length of production line, reduce the factory space occupancy rate, improve space utilization, simplify the structure and reduce the cost per unit.

[0023] Referring to Figure 1, the transmission mechanism 4 includes an output roller 41, a transmission roller 42, and a pressure roller 43. The output roller 41 is driven by a motor. The transmission roller 42 is rotatably connected to the inner surface of the frame 1. The pressure roller 43 is rotatably connected to the frame 1. The output roller 41, the transmission roller 42, and the pressure roller 43 all have breathable membranes on them. The output roller 41 is driven by a motor, so that the breathable membrane is driven on it. At the same time, the transmission roller 42 and the pressure roller 43 can limit the transmission of the breathable membrane, so that the material placed on the breathable membrane can be conveyed and moved, which facilitates the subsequent stripping of the material.

[0024] Referring to Figure 2, the feeding mechanism 3 includes a connecting frame 31, a transverse drive assembly 32, a cylinder 33, a connecting plate 34, a mounting component 35, and a suction cup clamp 36. The connecting frame 31 is detachably connected to the hopper frame 21. The transverse drive assembly 32 is mounted on the connecting frame 31 and is used to drive the cylinder 33 to move transversely. The connecting plate 34 is fixedly connected to the output end of the cylinder 33 and is fixedly connected to the mounting component 35. The suction cup clamp 36 is mounted on the mounting component 35. By driving the connecting plate 34 to rise and fall through the output end of the cylinder 33, the mounting component 35 can drive the suction cup clamp 36 to move up and down, thereby clamping the material. Furthermore, by using the transverse drive assembly 32, the material can be placed on the breathable membrane.

[0025] Multiple sets of suction cup clamps 36 are provided. These multiple sets of suction cup clamps 36 can be detachably installed on the mounting part 35 by bolts. The position of the suction cup clamps 36 is adjustable. In this way, it is convenient to adjust the position of the suction cup clamps 36 according to different sized materials.

[0026] Referring to Figures 4, 6, and 7, the pressing mechanism 5 includes a support frame 51, a placement plate 52, a cylinder 53, a crossbeam 54, and a pressing block 55. The placement plate 52 is fixedly connected to the support frame 51, the cylinder 53 is fixedly installed on the support frame 51, the crossbeam 54 is fixedly connected to the output end of the cylinder 53, and the pressing block 55 is installed on the crossbeam 54. The output end of the cylinder 53 drives the crossbeam 54 and the pressing block 55 to descend, which can press the material, so that the material can remain stable during the movement on the breathable membrane, prevent displacement and wrinkles, and facilitate subsequent peeling.

[0027] The bottom of the pressure roller 43 is flush with the upper side of the placement plate 52. In this way, the breathable membrane is attached to the placement plate 52 and moved. The cross frame 54 is provided with mounting holes 541. The pressure block 55 is adjusted in the mounting position on the cross frame 54 through the mounting holes 541, which can press materials of different sizes. The placement plate 52 is provided with through holes, and the through holes are connected to the connection port 521. The connection port 521 can be connected to the negative pressure component to form a negative pressure at the through holes, thereby sucking the material on the breathable membrane.

[0028] Referring to Figures 4-5, the support mechanism 6 includes a second support frame 61, a second placement plate 62, a second stepper motor 63, a second gear 64, a second rack 65, a mounting base 66, and a second guide rail 67. The second support frame 61 is slidably connected to the second guide rail 67, and the second guide rail 67 is fixedly connected to the frame 1. The second placement plate 62 is fixedly connected to the second support frame 61 and is flush with the first placement plate 52. The second stepper motor 63 is fixedly mounted on the second support frame 61, and the second gear 64 is fixedly connected to the output shaft of the second stepper motor 63. The gear 64 meshes with the rack 65, which is fixedly mounted on the mounting base 66. The mounting base 66 is fixedly connected to the frame 1. By starting the stepper motor 63, the gear 64 is driven to rotate. Under the action of the rack 65 and the guide rail 67, the support frame 61 and the placement plate 62 move, thereby maintaining support for the material during the stripping process. The placement plate 62 of the support mechanism 6 moves synchronously, providing stable support for the material during the stripping process, preventing the material from deforming due to uneven force, and ensuring stable material supply.

[0029] It should be noted that components such as the hopper frame 21 and connecting frame 31 are connected to the machine frame 1 by bolts, and disassembly and assembly do not require complicated tools. Key components such as the lifting platform 22 of the hopper feeding mechanism 2 and the suction cup clamp 36 of the feeding mechanism 3 can be disassembled, repaired, or replaced individually. When a certain module malfunctions, it is not necessary to stop the machine and disassemble the entire machine, effectively shortening maintenance time and reducing production line downtime losses. All the above electrical components are existing technology products. Those skilled in the art can select, install, and complete the circuit debugging work according to the needs of use to ensure that all electrical appliances can work normally. All components are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. No specific restrictions are made here. The standard parts used in this application can all be purchased from the market. The specific connection methods of each part are all connected by conventional means such as riveting and welding that are mature in the prior art. The standard parts are all conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art.

[0030] Working principle: When in use, the strip containing electrode sheets, separators and other sheet materials is first placed on the lifting platform 22 of the material feeding mechanism 2. The stepper motor 23 is started according to the height of the strip, which drives the gear 24 to rotate. Under the guiding and limiting action of the rack 25, the limit plate 26 and the guide rail 27, the lifting platform 22 is stably raised and lowered to the appropriate feeding position to complete the feeding preparation.

[0031] Then, the feeding mechanism 3 is activated. The output end of cylinder 33 drives the connecting plate 34 and the mounting part 35 to descend. Multiple sets of position-adjustable suction cups 36 adsorb the material on the material belt. The lateral movement drive assembly 32 drives cylinder 33 to move laterally, transferring the material to the breathable membrane above the transmission mechanism 4. The suction cups 36 release the material, allowing it to fall smoothly onto the breathable membrane. At the same time, the motor of the transmission mechanism 4 is activated, driving the output roller 41 to rotate, which in turn drives the breathable membrane along the transmission roller 42 and the pressure roller 43. The bottom of the pressure roller 43 is flush with the upper side of the placement plate 52, ensuring that the breathable membrane moves smoothly and adheres to the placement plate 52.

[0032] When the material is conveyed along the breathable membrane to the area below the pressing mechanism 5, cylinder 53 drives the crossbeam 54 and the pressure block 55 to descend. The pressure block 55, adjusted according to the material size, presses the material firmly onto the breathable membrane. Simultaneously, the connection port 521 connects to the negative pressure component, creating negative pressure at the through hole of the placement plate 52, further tightening the material and preventing it from shifting or wrinkling. Next, the stepper motor 63 of the support mechanism 6 is activated, driving gear 64 to rotate. Under the action of rack 65 and guide rail 67, the support frame 61 moves synchronously with the placement plate 62, making the placement plate 62 flush with the placement plate 52, providing stable support for the material.

[0033] Finally, adjust the height adjustment component at the bottom of the peeling plate 7 to make the peeling plate 7 adapt to the material thickness; when the material moves to the peeling plate 7 with the breathable membrane, the bottom paper separates from the material, completing the peeling operation.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
