Description

Technical Field

[0001] This utility model relates to the field of feeding machine technology, and in particular to a lifting and distributing mechanism for a feeding machine used for feeding aluminum foil for lithium batteries. Background Technology

[0002] Existing feeders are widely used in various industries for conveying products such as granules, powders, flakes, and strips. Many current working conditions require feeders for material feeding, and since many are at considerable heights, manual operation is inconvenient and unsafe. Therefore, many feeders with lifting functions have emerged. In addition, there are many patented technologies involved.

[0003] For example, Chinese Patent Application No. 202121568430.5 discloses a feeder with easy lifting control, including a sliding base block and a motor stabilizing block. A stabilizing lifting mechanism for controlling the lifting of the device is provided on the top of the sliding base block. A connecting mechanism is fixedly connected to the side of the stabilizing lifting mechanism. The stabilizing lifting mechanism includes a power motor, a control rod, and a threaded lifting block. This feeder with easy lifting control utilizes a motor stabilizing block fixedly connected to the top of the sliding base block. The motor stabilizing block consists of a motor housing at the bottom and a support plate at the top. A rod hole is provided on the top of the support plate, allowing control of the stability of the support stabilizing block and the stabilizing ring. The power motor is fixed within the motor housing of the motor stabilizing block. The rotation of the control rod is controlled by the power motor. The threaded connection between the control rod and the threaded lifting block allows control of the lifting of the threaded lifting block.

[0004] Chinese Patent Application No. 202122015776.9 discloses a hopper lifting assembly, including a hopper rack for placing hoppers and a lifting drive mechanism for driving the hopper rack to move up and down for feeding materials. The lifting drive mechanism includes a mounting bracket, a rotary motor, a lead screw, a first nut seat, and a second nut seat. The rotary motor enables the lead screw to rotate, and the axis of the lead screw is along the vertical direction. The first nut seat and the second nut seat are spaced apart on the lead screw along the vertical direction, and both the first nut seat and the second nut seat are connected to the hopper rack. This hopper lifting assembly ensures accurate displacement of the hopper rack and prevents the hopper rack from shaking during movement.

[0005] For example, Chinese Patent Application No. 202022366571.0 discloses a lifting and feeding mechanism for a feeder, including a bracket. A base is fixedly connected to the bottom of the bracket, and a lifting motor is fixedly connected to the top of the bracket. A lead screw is fixedly connected to the output shaft of the lifting motor. A bearing seat is fixedly connected to the bottom of the outer surface of the lead screw. A slider is threadedly connected to the outer surface of the lead screw. A limit block is fixedly connected to the right side of the slider. A connecting rod is fixedly connected to the left side of the slider. A fixing plate is fixedly connected to the left side of the connecting rod. Connecting rods are fixedly connected to both the upper and lower ends of the right side of the fixing plate.

[0006] The existing feeding equipment has a large lifting and feeding section that occupies a lot of space and is prone to encountering obstacles, which can cause danger. The structure itself is not optimized for protection. Utility Model Content

[0007] The purpose of this invention is to provide a lifting and distributing mechanism for a feeding machine that is more flexible and safer.

[0008] The above-mentioned objective of this utility model is achieved through the following technical solution: a lifting and distributing mechanism for a feeding machine, comprising an upright lifting support panel, a drive mechanical arm for picking up and placing materials is installed and connected to the front side of the lifting support panel, the drive mechanical arm can be unfolded and folded between the front and rear, and an elastic lifting component for lifting and lowering is connected to the rear side of the lifting support panel.

[0009] As a preferred embodiment of the present invention, the elastic lifting assembly includes a lifting slider that is fitted onto the lead screw and can move up and down with the rotation of the lead screw, and a floating mounting connecting block that is elastically supported on the lifting slider. The rear side of the lifting support panel is fixed to the front side of the floating mounting connecting block.

[0010] As a preferred embodiment of this utility model, the left and right sides of the lead screw hole of the lifting slider are supported and abutted against the floating mounting connecting block by upper and lower support springs.

[0011] As a preferred embodiment of this utility model, a first travel limit switch is installed and connected on the lifting slider, and a first trigger rod that cooperates with the first travel limit switch is installed and connected on the floating mounting connecting block. Under normal conditions, there is a gap between the first trigger rod and the first travel limit switch. When the feeding load is overloaded or an obstacle is encountered during the upward movement, the first trigger rod approaches the first travel limit switch, thereby triggering the switch to stop the upward movement.

[0012] As a preferred embodiment of this utility model, a second travel limit switch is installed and connected on the lifting slider, and a second trigger rod that cooperates with the second travel limit switch is installed and connected on the floating mounting connecting block. The second trigger rod and the second travel limit switch are in contact with each other in the normal state. When the material encounters an obstacle during the downward feeding process, the second trigger rod disengages from the second travel limit switch, thereby triggering the switch to stop the downward movement.

[0013] As a preferred embodiment of this utility model, an upper and lower guide rod is further provided between the floating mounting connecting block and the lifting slider for the upper and lower support springs to be sleeved and for the upper and lower guide functions.

[0014] As a preferred embodiment of the present invention, the driving robotic arm includes an upper first fixing plate and a lower first fixing plate that are fixed to the lifting support panel and are spaced apart vertically; a first movable arm that is hinged between the upper and lower first fixing plates; and a plurality of unfolding folding arms that are sequentially hinged to the other end of the first movable arm and can be folded and unfolded inside and outside the first movable arm. The unfolded folding arm that is forward after unfolding serves as the direct feeding arm.

[0015] As a preferred embodiment of this utility model, a first hinge shaft is connected between the upper first fixed plate and the lower first fixed plate. The first movable arm includes two first arm plates that are spaced apart vertically. One end of each first arm plate passes through the first hinge shaft, and the other ends of the two first arm plates are connected to a movable hinge shaft for unfolding and folding. Except for the unfolding and folding arm that serves as a direct feeding arm, all unfolding and folding arms include two unfolding and folding plates that are spaced apart vertically. The two ends of each of the two unfolding and folding plates are connected through a movable hinge shaft. The unfolding and folding arm that serves as a direct feeding arm includes only one unfolding and folding plate, and only one end of it passes through the movable hinge shaft.

[0016] As a preferred embodiment of this utility model, the upper first fixing plate, the lower first fixing plate, the first arm plate, and the unfolding folding plate are provided with locking holes that pass through the upper and lower parts on the outer periphery near the corresponding hinge axis and are used to lock the first arm plate and the unfolding folding plate.

[0017] As a preferred embodiment of this utility model, guide rail blocks for guiding and sliding on the guide rail are also fixed on the left and right sides of the rear side of the lifting support panel.

[0018] The beneficial effects of this utility model are: the folding mechanism allows the drive robotic arm to extend and retract, thus adapting to different working conditions; it can be folded after use to reduce space occupation and make it more flexible to use; it adds more protective structures, allowing for timely response in case of accidents, reducing damage to the equipment, and making it safer and more reliable to use.

[0019] It is ideal for handling and conveying materials such as aluminum foil used in lithium batteries. Of course, it is not limited to materials in roll form such as aluminum foil; as long as there are appropriate tooling and carrying equipment, most materials can be lifted and delivered.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings.

[0026] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of the present utility model.

[0027] Examples, such as Figure 1-5 As shown, a lifting and distributing mechanism for a feeder includes an upright lifting support panel 1. A drive robotic arm for picking up and placing materials is installed and connected to the front side of the lifting support panel 1. The drive robotic arm can be unfolded and folded between the front and rear. An elastic lifting component for lifting and lowering is connected to the rear side of the lifting support panel 1. Two key features of this application are: the unfoldable and foldable drive robotic arm design allows for adjustments to the length and direction of the drive robotic arm based on actual working conditions, resulting in better applicability, greater flexibility, and easier storage; and the elastic lifting component, which provides elastic support during the lifting process, effectively cushions collisions and provides better protection for the equipment.

[0028] Specifically, the elastic lifting assembly includes a lifting slider 21 that is fitted onto a lead screw and can move up and down with the rotation of the lead screw, and a floating mounting connecting block 22 elastically supported on the lifting slider 21. The rear side of the lifting support panel 1 is fixed to the front side of the floating mounting connecting block 22. The lifting slider 21 has a lead screw hole. After the lead screw passes through, the forward or reverse rotation of the lead screw realizes the lifting of the lifting slider 21. This is a conventional technology. The difference is that the floating mounting connecting block 22 is elastically supported and connected to the lifting slider 21, rather than being a fixed connection. The floating mounting connecting block 22 is fixed to the lifting support panel 1. The fixing method can be achieved by existing methods such as bolts or welding. In this way, the lifting of the lifting slider 21 also moves the floating mounting connecting block 22 up and down, and of course, it also moves the lifting support panel 1 and the driving robotic arm on the lifting support panel 1 up and down. During the lifting process, if the driving robotic arm encounters obstacles, causing the floating mounting connecting block 22 to move out of sync or even in the opposite direction to the lifting slider 21, the elastic force can effectively buffer the movement and protect the equipment.

[0029] Preferably, the left and right sides of the lead screw hole 210 of the lifting slider 21 are supported and abutted against the floating mounting connecting block 22 by upper and lower support springs 3. The upper and lower support springs 3 extend vertically to provide elastic support for the floating mounting connecting block 22. The floating mounting connecting block 22 can be a U-shaped structural block with the opening facing backward. The hollow part of the U-shape in the middle of the floating mounting connecting block 22 is aligned vertically with the lead screw hole 210, so that the lead screw can avoid obstruction. Two upper and lower support springs 3 can be set vertically between the left half of the floating mounting connecting block 22 and the left side of the lead screw hole 210 of the lifting slider 21, and between the right half of the floating mounting connecting block 22 and the right side of the lead screw hole 210 of the lifting slider 21, and spaced apart, so that the force is more evenly distributed and stable.

[0030] Furthermore, an upper and lower guide rod 30 is provided between the floating mounting connecting block 22 and the lifting slider 21 for the upper and lower support springs 3 to be fitted and for the upper and lower guide functions. Each upper and lower support spring 3 is equipped with an upper and lower guide rod 30. The upper and lower guide rod 30 can be fixed on the floating mounting connecting block 22 or the lifting slider 21. The floating mounting connecting block 22 and the lifting slider 21 need to have holes for the upper and lower guide rods 30 to pass through, because there will be vertical displacement between the floating mounting connecting block 22 and the lifting slider 21. Especially when the upper and lower guide rods 30 are relatively long, these holes need to not affect the elastic floating displacement of the floating mounting connecting block 22 relative to the lifting slider 21. These holes can also be understood as guide holes of the upper and lower guide rods 30 themselves.

[0031] Next, we will introduce the further safety protection structure. A first travel limit switch 41 is fixedly connected to the lifting slider 21. A first trigger rod 411, which cooperates with the first travel limit switch 41, is fixedly connected to the floating mounting connecting block 22. Under normal conditions, there is a gap between the first trigger rod 411 and the first travel limit switch 41. When the feeding load is overloaded or an obstacle is encountered during the upward movement, the first trigger rod 411 approaches the first travel limit switch 41, thereby triggering the switch to stop the upward movement. The principle is that, under normal conditions, the first trigger rod 411 and the first travel limit switch 41 are close together. The distance between the upper and lower gaps of the position switch 41 can be set to an initial gap value T1 according to requirements. The compression of the upper and lower support springs 3 is the compression amount in the working feeding state, such as 5 mm. When the feeding material is overloaded, or when the driving robot arm encounters an obstacle above during the upward movement and cannot move, the floating mounting connecting block 22 is also blocked and cannot move, but the lifting slider 21 is still rising. In both of these situations, the upper and lower support springs 3 will be further compressed, so that the first trigger rod 411 will approach the first travel limit switch 41, thereby triggering the first travel limit switch 41 to shut down the equipment for emergency avoidance. The triggering condition can be that the first travel limit switch 41 is activated when it approaches a set threshold, or it can be activated after approaching the contact state. It can be selected according to actual needs. In this way, on the one hand, there is the buffering effect of the spring for protection, and on the other hand, the equipment can be shut down in time.

[0032] Preferably, a second travel limit switch 42 is fixedly connected to the lifting slider 21, and a second trigger rod 422 cooperating with the second travel limit switch 42 is fixedly connected to the floating mounting block 22. Under normal conditions, the second trigger rod 422 and the second travel limit switch 42 are in contact. When an obstacle is encountered during the downward feeding process, the second trigger rod 422 disengages from the second travel limit switch 42, thereby triggering the switch to stop the downward movement. The principle of this design is exactly the opposite of the previous protective measure; it works during the downward movement. That is, under normal conditions, the second trigger rod 422 and the second travel limit switch 42 are in contact. When an obstacle is encountered during the downward movement, the floating mounting block 22 cannot move downward, while the lifting slider 21 moves downward, causing the two to gradually separate. This results in the second trigger rod 422 disengaging from the second travel limit switch 42. When the disengagement reaches a set threshold, the second travel limit switch 42 is triggered to shut down the equipment.

[0033] The structures of the two sets of protective measures mentioned above can be set on the left and right sides of the lifting slider 21 and the floating mounting connecting block 22, respectively.

[0034] The driven robotic arm adopts a folding structure, which is achieved through hinged rotation. Specifically, the driven robotic arm includes an upper first fixed plate 511 and a lower first fixed plate 512, which are fixed to the lifting support panel 1 and spaced vertically. A first movable arm 61 is hinged between the upper and lower first fixed plates 511 and 512. Several unfolding folding arms 62 are hinged to the other end of the first movable arm 61, and can be folded and unfolded inside and outside the first movable arm 61. The foremost unfolding folding arm 62, when unfolded, serves as the direct feeding arm. The first movable arm 61 can rotate horizontally, but only in front of the lifting support panel 1, while the unfolding folding arms 62 can rotate 360 ​​degrees. Multiple unfolding folding arms 62 are hinged together at both ends. The first movable arm 61 and the unfolding folding arms 62 have an open, three-dimensional structure to facilitate unfolding and folding, as described later. The direct feeding arm is directly connected to the material or the structure that loads the material.

[0035] Furthermore, a first hinge shaft 71 connects the upper first fixed plate 511 and the lower first fixed plate 512. The first movable arm 61 includes two first arm plates 611 spaced vertically apart. One end of each first arm plate 611 passes through the first hinge shaft 71, and the other ends of the two first arm plates 611 are connected to a movable hinge shaft 72 for unfolding and folding. Except for the unfolding and folding arm that serves as a direct feeding arm, all unfolding and folding arms 62 include two unfolding and folding plates 622 spaced vertically apart. The two ends of each unfolding and folding plate 622 are connected by a movable hinge shaft 72. The unfolding and folding arm 62 that serves as a direct feeding arm includes only one unfolding and folding plate 622, and only one end of it passes through the movable hinge shaft 72. The vertical spacing between the two first arm plates 611 forms the internal space for folding and storing the unfolding and folding arm 62, while the vertical spacing between the two unfolding and folding plates 622 forms the internal space for folding and storing other unfolding and folding arms 62. The unfolding folding arm 62, which serves as the direct feeding arm, has some assembly holes on the unfolding folding plate 622 for assembling materials or structures that load materials.

[0036] Furthermore, the upper first fixing plate 511, the lower first fixing plate 512, the first arm plate 611, and the unfolding and folding plate 622 are provided with locking holes 60 on the outer periphery near the corresponding hinge axis. These holes are vertically connected and used to lock the first arm plate 611 and the unfolding and folding plate 622. Multiple locking holes 60 can be provided on each plate near the outer periphery of the corresponding hinge axis and spaced apart in the circumferential direction. This allows for more adjustable angles. When the first arm plate 611 and the unfolding and folding plate 622 are unfolded or folded to a certain angle, the locking holes 60 on the corresponding upper and lower mating plates are simultaneously inserted through the pins, and the locking is achieved in the circumferential direction. As a result, the entire driven robotic arm cannot move, and both the unfolding operation and the folding operation are relatively safe and stable.

[0037] In addition, guide rail blocks 8 are fixed on the left and right sides of the rear side of the lifting support panel 1 for guiding and sliding on the guide rail. This is to ensure the straightness of the lifting, and the feeder can be equipped with corresponding guide rails. This is also a fairly conventional design.

[0038] With the above design, the overall lifting operation is safer and more reliable, and it is applicable to a wider variety of working conditions, making it very suitable for modern production.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
