Description

Technical Field

[0001] This utility model relates to the technical field of aluminum belt conveying equipment, and in particular to an aluminum belt positioning component. Background Technology

[0002] Aluminum strip positioning assemblies are widely used in lithium battery electrode processing, flexible circuit board production, and packaging material slitting. Their core function is to ensure that the aluminum strip maintains a stable position during transmission, avoiding problems such as deviation and wrinkling. Due to the high ductility and easy deformation of aluminum strips, traditional conveying systems struggle to achieve high-precision positioning. Especially on high-speed production lines, even slight deviations in the aluminum strip can lead to a decrease in yield for subsequent processes. Utility Model Content

[0003] The purpose of this invention is to provide an aluminum strip positioning component, which aims to solve the technical problem that aluminum strips are prone to deviation during transmission.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] An aluminum strip positioning assembly includes a base frame, a drive roller, a first auxiliary roller, a mounting frame, a pressing structure, a linear drive device, and an electronic identification device.

[0006] The active roller is disposed on the base frame and can be actively driven; the first auxiliary roller is disposed on the mounting frame and rotates with the mounting frame; the pressing structure is fixed to the mounting frame and is used to cooperate with the first auxiliary roller; the mounting frame is slidably engaged with the base frame; the linear drive device is fixed to the base frame and is used to drive the mounting frame to move relative to the base frame; the electronic identification device is fixed to the base frame and is signal-connected to the linear drive device.

[0007] The aluminum strip passes sequentially through the electronic identification device, the first auxiliary roller, and the active roller.

[0008] In one embodiment, a rubber layer is formed on the surface of the first auxiliary roller.

[0009] In one embodiment, the pressing structure is driven by a cylinder and includes a pressure plate; the mounting bracket is provided with a limit adjustment member, which is used to adjust the pressing stroke of the pressure plate.

[0010] In one embodiment, a second auxiliary roller and a third auxiliary roller are also mounted on the base frame; the aluminum strip passes sequentially through the electronic identification device, the third auxiliary roller, the second auxiliary roller, and the first auxiliary roller;

[0011] The second auxiliary roller is positioned relative to the first auxiliary roller in a direction away from the pressure plate, and the third auxiliary roller is positioned close to the electronic identification device.

[0012] In one embodiment, the active roller is positioned relative to the first auxiliary roller in a direction away from the force applied to the pressure plate; the aluminum strip is alternately passed through the active roller, the first auxiliary roller, the second auxiliary roller, and the third auxiliary roller in sequence.

[0013] In one embodiment, the linear drive device includes a lead screw, a nut, and a motor; the motor is fixed to the base frame and is used to drive the lead screw to rotate; the other end of the lead screw is rotatably engaged with the base frame; the nut is threadedly engaged with the lead screw; the nut is fixedly connected to the mounting bracket through a connector, and the connector is slidably engaged with the base frame.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The aluminum strip positioning assembly described in this invention uses an electronic identification device to detect the aluminum strip position in real time and feeds the signal back to a linear drive device. This drive device moves the mounting frame to adjust the first auxiliary roller and the pressing structure, forming a closed-loop control.

It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component centrally located at the same time.

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] This utility model embodiment provides an aluminum strip positioning assembly 100.

[0025] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the aluminum strip positioning assembly 100 includes a base frame 110, an active roller 120, a first auxiliary roller 130, a mounting frame 140, a pressing structure 150, a linear drive device 160, and an electronic identification device 170.

[0026] The active roller 120 is disposed on the base frame 110 and is actively driven; the first auxiliary roller 130 is disposed on the mounting frame 140 and rotates with the mounting frame 140; the pressing structure 150 is fixed to the mounting frame 140 and is used to cooperate with the first auxiliary roller 130; the mounting frame 140 is slidably engaged with the base frame 110; the linear drive device 160 is fixed to the base frame 110 and is used to drive the mounting frame 140 to move relative to the base frame 110; the electronic identification device 170 is fixed to the base frame 110 and is signal-connected to the linear drive device 160.

[0027] The aluminum strip 200 passes sequentially through the electronic identification device 170, the first auxiliary roller 130, and the active roller 120.

[0028] It is understood that in this embodiment, the aluminum strip positioning component 100 detects the position of the aluminum strip 200 in real time through the electronic identification device 170 and feeds the signal back to the linear drive device 160, which drives the mounting frame 140 to move and adjust the first auxiliary roller 130 and the pressing structure 150, forming a closed-loop control. This effectively solves the technical problem of easy wrinkling of the aluminum strip 200 during the winding and correction process. Specifically, the active roller 120 and the first auxiliary roller 130 work together to pull the aluminum strip 200, and the flexible pressing of the pressing structure 150 avoids the rigid contact damage of the traditional fixed pressure roller. In addition, the sliding fit design between the mounting frame 140 and the base frame 110 allows the position of the aluminum strip 200 to be dynamically adjusted. Therefore, this utility model overcomes the wrinkling defects caused by the passive correction process of the aluminum strip 200 in the prior art; it achieves high-precision, adaptive positioning of the aluminum strip 200 and improves production quality.

[0029] Furthermore, a rubber layer is formed on the surface of the first auxiliary roller 130.

[0030] Specifically, the base frame 110 refers to the main frame supporting the entire assembly, which can be made of welded metal profiles or cast aluminum alloy; the active roller 120 refers to a rotating roller driven by a motor, whose surface can be chrome-plated or coated with polyurethane to enhance friction; the first auxiliary roller 130 is a driven roller, which is rotatably connected to the mounting frame 140 through bearings; the mounting frame 140 is a sliding component, made of steel plate, used to support the auxiliary roller and the pressing structure 150; the pressing structure 150 includes a pressure plate 152 and a drive mechanism, used to apply slight pressure to the aluminum strip 200; the linear drive device 160 can be a screw and nut mechanism, a linear motor or a hydraulic cylinder, used to precisely adjust the position of the mounting frame 140; the electronic identification device 170 includes a photoelectric sensor or an ultrasonic sensor, used to detect the edge position of the aluminum strip 200.

[0031] Understandably, the active roller 120 is fixed to the base frame 110 and connected to the servo motor via a coupling to achieve rotational drive; the first auxiliary roller 130 is rotatably connected to the mounting frame 140 via a bearing, allowing the aluminum strip 200 to pass smoothly; the pressing structure 150 is fixed to the mounting frame 140 by bolts, and its pressure plate 152 is aligned vertically with the first auxiliary roller 130 to form a clamping adjustment area; the mounting frame 140 slides with the base frame 110 via a linear guide rail to ensure smooth movement; optionally, one end of the lead screw 161 of the linear drive device 160 is connected to the motor 163, and the other end is rotatably connected to the base frame 110 via a bearing seat, and the nut 162 is fixed to the mounting frame 140 via a connector 141, thereby converting rotational motion into linear motion; the electronic identification device 170 is fixed to the inlet side of the base frame 110 via a bracket, and its signal output end is electrically connected to the controller of the linear drive device 160 to form a closed-loop feedback.

[0032] It should also be explained that, in this embodiment, the coordinated drive of the active roller 120 and the auxiliary roller prevents the aluminum strip 200 from slipping, and the cooperation between the pressing structure 150 and the sliding mounting bracket 140 achieves non-rigid contact pressing, reducing surface damage to the aluminum strip 200. The overall solution achieves high-precision, adaptive positioning of the aluminum strip 200.

[0033] Furthermore, the pressing structure 150 is driven by a cylinder 151, and the pressing structure 150 includes a pressure plate 152; the mounting bracket 140 is provided with a limit adjustment member 153, which is used to adjust the pressing stroke of the pressure plate 152.

[0034] Specifically, cylinder 151 can be an adjustable-stroke cylinder; pressure plate 152 is a rectangular or arc-shaped metal plate; limit adjustment element 153 can be an electronic limit switch, used to precisely control the pressing end position of pressure plate 152. Optionally, cylinder 151 can also be replaced by an electric push rod or a hydraulic cylinder.

[0035] Understandably, the cylinder body of cylinder 151 is vertically fixed to the top of mounting bracket 140 via a flange, and the end of its piston rod can be hinged to pressure plate 152 via a fisheye connector (not shown), or flexibly fitted to pressure plate 152 via a rubber strip; pressure plate 152 is arranged parallel to the first auxiliary roller 130 directly above it, and the gap between the two is adjusted by the pressure of cylinder 151; limit adjustment component 153 is an electronic limit switch installed on mounting bracket 140 to ensure the adjustable pressing force and prevent damage to aluminum strip 200.

[0036] Please continue reading. Figure 1 and Figure 2In another embodiment of the present invention, the aluminum strip 200 positioning mechanism further includes a second auxiliary roller 180 and a third auxiliary roller 190 installed on the base frame 110; the aluminum strip 200 passes sequentially through the electronic identification device 170, the third auxiliary roller 190, the second auxiliary roller 180 and the first auxiliary roller 130.

[0037] The second auxiliary roller 180 is positioned relative to the first auxiliary roller 130 in a direction away from the pressure plate 152, and the third auxiliary roller 190 is positioned close to the electronic identification device 170.

[0038] Specifically, the second auxiliary roller 180 and the third auxiliary roller 190 are both driven rollers with smooth surfaces, used to guide the aluminum strip 200 during horizontal movement and prevent wrinkles from forming. The second auxiliary roller 180 is used to form a reverse tension with the first auxiliary roller 130, and the third auxiliary roller 190 is located near the electronic identification device 170, mainly used for initial guidance when the aluminum strip 200 enters the system; the two ends of the second auxiliary roller 180 and the third auxiliary roller 190 are rotatably connected to the base frame 110 through bearings.

[0039] It should also be explained that the second auxiliary roller 180 is installed diagonally below the first auxiliary roller 130, forming an "S"-shaped belt-threading path with the first auxiliary roller 130 to enhance tension control of the aluminum strip 200 during horizontal displacement. The third auxiliary roller 190 is positioned close to the electronic identification device 170 and mounted on the base frame 110, its position ensuring smooth entry and exit of the aluminum strip 200 from the detection area. The aluminum strip 200 sequentially passes around the third auxiliary roller 190, the second auxiliary roller 180, and the first auxiliary roller 130, and is finally pulled by the drive roller 120. This arrangement forces the aluminum strip 200 to maintain a predetermined path through geometric constraints, avoiding deviation and reducing the probability of the aluminum strip 200 deviating from its intended path at the source.

[0040] Furthermore, the active roller 120 is positioned relative to the first auxiliary roller 130 in a direction away from the force applied to the pressure plate 152; the aluminum strip 200 is alternately threaded through the active roller 120, the first auxiliary roller 130, the second auxiliary roller 180, and the third auxiliary roller 190 in sequence.

[0041] Understandably, the drive roller 120 is located on the opposite side of the force applied by the pressure plate 152. For example, if the pressure plate 152 presses the aluminum strip 200 downwards, the drive roller 120 is positioned above the first auxiliary roller 130; conversely, if the pressure plate 152 presses upwards, the drive roller 120 is positioned below. This arrangement ensures a natural transition between the pressing and traction zones of the aluminum strip 200, avoiding stress concentration in the material caused by sharp bends.

[0042] Optionally, the lowest point of the active roller 120 is slightly lower than the highest point of the first auxiliary roller 130.

[0043] Preferably, the lowest point of the active roller 120 is aligned with the highest point of the first auxiliary roller 130 to achieve natural traction of the aluminum strip 200.

[0044] It is also understandable that the aluminum strip 200 follows a continuous "S"-shaped wave pattern between adjacent rollers, rather than being simply layered vertically. For example, if the third auxiliary roller 190 is a high-position roller, the aluminum strip 200 will extend upwards to the second auxiliary roller 180 after passing under it, then fold back downwards to the first auxiliary roller 130, and finally wind upwards to the drive roller 120. This alternating threading method forces the aluminum strip 200 to remain taut through geometric constraints, preventing the aluminum strip 200 from becoming slack or clumped.

[0045] Please see Figure 1 In one specific embodiment, the linear drive device 160 includes a lead screw 161, a nut 162, and a motor 163; the motor 163 is fixed to the base frame 110, and the motor 163 is used to drive the lead screw 161 to rotate; the other end of the lead screw 161 is rotatably engaged with the base frame 110; the nut 162 is threadedly engaged with the lead screw 161; the nut 162 is fixedly connected to the mounting bracket 140 through a connector 141, and the connector 141 is slidably engaged with the base frame 110.

[0046] Specifically, the lead screw 161 is a transmission element, typically a ground ball screw 161 or a trapezoidal lead screw 161; the nut 162 is a matching component that matches the lead screw 161, and may contain a ball recirculation structure to reduce friction; the motor 163 is preferably a servo motor or a stepper motor, and has an encoder feedback function to achieve closed-loop control; the connector 141 is generally a metal part, used to rigidly connect the nut 162 and the mounting bracket 140; the sliding fit between the connector 141 and the base frame 110 can be achieved through linear guides, slide rails or guide grooves to ensure stable and reliable movement.

[0047] It is also understood that the motor 163 is fixed to the base frame 110 via a flange, and its output shaft is directly connected to one end of the lead screw 161 via a coupling; the other end of the lead screw 161 forms a rotating pair with the base frame 110 via an angular contact bearing or a sliding bearing; the internal thread of the nut 162 precisely engages with the external thread of the lead screw 161, and its outer wall is fixed to the connecting piece 141 via bolts; the other end of the connecting piece 141 is rigidly connected to the mounting frame 140, which can be welded or bolted. Simultaneously, a slider can be provided at the bottom of the connecting piece 141 to engage with the guide rail on the base frame 110. When the motor 163 drives the lead screw 161 to rotate, the nut 162 moves axially along the lead screw 161, thereby driving the entire mounting frame 140 and the first auxiliary roller 130 to move synchronously through the connecting piece 141, achieving precise adjustment of the pressing position.

[0048] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
