Description

Technical Field

[0001] This application relates to the field of conveying devices, and more particularly to a conveying device for a metal strip. Background Technology

[0002] Metal strips are frequently used in the production of photovoltaic products, and are widely applied in key processes such as cell stringing, conductive connections, and frame encapsulation. Transporting these metal strips requires specialized conveyor systems. Existing conveyor systems commonly use belt conveyors, where the rotation of rollers drives the movement of a transmission belt, thus transporting the metal strips placed on the belt surface. However, these systems are mostly suitable for transporting large-volume metal strips. Using them for transporting small metal strips can easily lead to stretching, deformation, or scratches, affecting their subsequent use.

[0003] In response to the aforementioned related technologies, the inventors provide a conveying device suitable for small metal strips. Utility Model Content

[0004] To ensure stable conveying of metal strips, this application provides a metal strip conveying device.

[0005] The metal strip conveying device provided in this application adopts the following technical solution:

[0006] A conveying device for metal strip includes a frame, a limiting mechanism mounted on the top surface of the frame for limiting the metal strip, and a transport mechanism mounted on the top surface of the frame for conveying the metal strip. The transport mechanism includes a sliding seat slidably mounted on the top surface of the frame, a sliding drive for driving the sliding seat to slide, and a clamping member mounted on the sliding seat and abutting against the metal strip. The sliding seat has a mounting slot for the metal strip to pass through. After being driven by the sliding drive, the sliding seat has a first station and a second station. When the sliding seat is in the first station, the clamping member abuts against the top surface of the metal strip. When the sliding seat is in the second station, there is a sliding gap between the clamping member and the metal strip.

[0007] By adopting the above technical solution, during the conveying process of the metal strip, the limiting mechanism limits the conveyed metal strip, reducing the probability of the metal strip deviating during the conveying process. Then, the clamping component presses the metal strip against the top surface of the frame. The sliding drive component drives the sliding seat to slide the clamping component, thereby realizing the transport of the metal strip on the top surface of the frame. When the sliding seat slides from the first station to the second station, the clamping component disengages from the top surface of the metal strip, and the sliding drive component drives the sliding seat to return to the first station. By switching the sliding seat between the first station and the second station, the metal strip is transported smoothly during the conveying process.

[0008] Optionally, the limiting mechanism includes two opposing limiting plates and a telescopic assembly for driving the limiting plates to move. The telescopic assembly includes a bidirectional lead screw rotatably mounted on the top surface of the frame, a drive motor for driving the bidirectional lead screw to rotate, a first nut mounted on one of the limiting plates and cooperating with one section of the bidirectional lead screw, and a second nut mounted on the other limiting plate and cooperating with the other section of the bidirectional lead screw.

[0009] By adopting the above technical solution, the specific structure of the limiting mechanism is disclosed. By driving the rotation of the bidirectional lead screw with a drive motor, the distance between the two limiting plates installed on the bidirectional lead screw is automatically adjusted. Compared with manual adjustment, the working efficiency is more ideal, and the metal strip conveying device can adapt to metal strips of various widths, thus improving the flexibility of the metal strip conveying device.

[0010] Optionally, the clamping component includes a clamping cylinder and a clamping block mounted on the top surface of the piston rod of the clamping cylinder, wherein the piston rod of the clamping cylinder extends toward the metal strip.

[0011] By adopting the above technical solution, the clamping block is driven by the clamping cylinder, which enables the clamping block to clamp the metal strip efficiently and quickly. This, in turn, drives the metal strip to be transported by the sliding seat, thus achieving stable transportation of the metal strip.

[0012] Optionally, one side of the sliding seat has a limiting portion protruding away from the sliding seat, and the top surface of the frame is provided with a limiting block and the limiting block has a sliding groove for the limiting portion to slide.

[0013] By adopting the above technical solution, the cooperation between the limiting part of the sliding seat and the sliding groove of the limiting block helps to guide the sliding process of the sliding seat, reduce the probability of the sliding seat deviating during the sliding process, and ensure the stable conveying of the metal strip.

[0014] Optionally, the top surface of the frame is provided with a guide rail, and the sliding seat is provided with a guide groove that cooperates with the guide rail.

[0015] By adopting the above technical solution, the cooperation between the guide rail and the guide groove on the sliding seat helps to guide the sliding of the sliding seat, further improves the stability of the sliding seat during the sliding process on the top surface of the frame, helps to reduce the probability of the sliding seat shaking during the sliding process, improves the accuracy of position control during the metal strip conveying process, and thus ensures the operational stability of the clamping parts on the metal strip.

[0016] Optionally, the piston rod of the clamping cylinder is arranged vertically on the center line of the bidirectional lead screw, and the guide rail is offset on the center line of the bidirectional lead screw.

[0017] By adopting the above technical solution, the piston rod of the clamping cylinder is vertically arranged on the center line of the double-acting screw, enabling the clamping cylinder to drive the clamping block to engage with the center of the metal strip, ensuring the stability of the clamping cylinder's operation on the metal strip. The guide rail is offset on the center line of the double-acting screw, which helps reduce the probability of the guide rail interfering with the clamping action of the clamping cylinder, ensuring the smooth sliding of the sliding seat while guaranteeing the normal transport of the metal strip.

[0018] Optionally, the frame is provided with a straightening assembly on the side of the limiting mechanism facing away from the transport mechanism. The straightening assembly includes two opposing support plates and two rotating shafts rotatably connected to the support plates. The two rotating shafts are arranged vertically at intervals along an axis perpendicular to the top surface of the frame, and there is a feeding gap between the two rotating shafts for the metal strip to pass through.

[0019] By adopting the above technical solution, the specific structure of the straightening component is disclosed. The metal sheet being transported to the transport mechanism is made possible by the arrangement of two rotating shafts.

[0020] The metal strip can be stably guided into the conveying device. Specifically, the straightening assembly effectively ensures the accurate positioning of the metal strip before entering the conveying mechanism, and can flatten and straighten the metal strip, making its surface smoother and providing better conditions for subsequent transportation. Two opposing support plates provide a stable support structure for the rotating shafts, and the two rotating shafts arranged vertically and horizontally form a reasonable feeding gap, further ensuring the smooth passage of the metal strip, thereby improving the working efficiency and reliability of the entire conveying device.

[0021] Optionally, the top surface of the frame is provided with a trapezoidal groove, and a mounting pad can be detachably installed in the trapezoidal groove, with the top surface of the mounting pad being flush with the top surface of the frame.

[0022] By adopting the above technical solution, the trapezoidal groove on the frame provides a stable installation platform for the mounting pads. The detachable installation of the mounting pads facilitates maintenance and replacement, reduces the probability that the clamping parts cannot stably cooperate with the metal strip due to wear on the top surface of the mounting pads, and ensures the stable transportation of the metal strip.

[0023] Optionally, the bottom of the mounting pad is provided with a mounting slider, the trapezoidal groove is provided with a mounting groove for arranging the mounting slider, and the trapezoidal groove is provided with a positioning groove at the mounting groove. The mounting slider is provided with a plunger hole, and a ball-head spring plunger is provided in the plunger hole. When the plunger ball of the ball-head spring plunger is engaged with the positioning groove, the mounting pad is installed in the trapezoidal groove.

[0024] By adopting the above technical solution, the mounting pad can be quickly positioned and stably installed in the trapezoidal groove through the cooperation between the mounting slider on the mounting pad and the mounting groove in the trapezoidal groove, as well as the cooperation between the positioning groove and the plunger ball of the ball spring plunger, thereby reducing the probability of the mounting pad becoming loose during use.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. A conveying device for metal strip, wherein the metal strip is limited by a limiting mechanism, and the pressing member abuts against the top surface of the metal strip, and the sliding drive member drives the sliding seat to slide, thereby realizing the movement of the metal strip driven by the pressing member, and the sliding drive member drives the sliding seat to switch repeatedly between the first station and the second station to realize the smooth transportation of the metal strip.

[0027] 2. The straightening components can be used to flatten and straighten the metal strip, making its surface smoother and providing better conditions for subsequent transportation.

[0028] 3. The trapezoidal groove and the detachable mounting pad installed in the trapezoidal groove help reduce the probability that the clamping part cannot stably cooperate with the metal strip due to wear on the top surface of the mounting pad, thus ensuring the stable transportation of the metal strip.

Detailed Implementation

[0037] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0038] This application discloses a conveying device for metal strips. (Refer to...) Figure 1 A conveying device for metal strip includes a frame 1, a straightening assembly 2 mounted on the top surface of the frame 1, a limiting mechanism 3 mounted on the top surface of the frame 1, and a transport mechanism 4 mounted on the top surface of the frame 1 and located on the side of the limiting mechanism 3 facing away from the straightening assembly 2. The top surface of the frame 1 is a plane.

[0039] Reference Figure 1 and Figure 2To limit the movement of the metal strip conveyed to the transport mechanism 4 and ensure stable cooperation between the transport mechanism 4 and the metal strip, a limiting mechanism 3 is provided on the top surface of the frame 1 between the straightening assembly 2 and the transport mechanism 4. The limiting mechanism 3 includes two limiting plates 31 slidably mounted on the top surface of the frame 1 and arranged opposite each other, and a telescopic assembly 32 that drives the limiting plates 31 to move. The telescopic assembly 32 includes a bidirectional lead screw 321 rotatably mounted on the top surface of the frame 1, a drive motor 322 that drives the bidirectional lead screw 321 to rotate, a first nut 323 mounted on one limiting plate 31 and engaging with one section of the bidirectional lead screw 321, and a second nut 324 mounted on the other limiting plate 31 and engaging with the other section of the bidirectional lead screw 321. By driving the bidirectional lead screw 321 to rotate via the drive motor 322, the distance between the two limiting plates 31 is adjusted, allowing the metal strip conveying device to adapt to metal strips of various widths, thus improving the flexibility of the metal strip conveying device.

[0040] Reference Figure 3 and Figure 4 The transport mechanism 4 includes a sliding seat 41 slidably mounted on the top surface of the frame 1, a sliding drive member 42 for driving the sliding seat 41 to slide, and a clamping member 43 mounted on the sliding seat 41 and engaging with the metal strip. The sliding seat 41 has a mounting slot 411 for the metal strip to pass through. The clamping member 43 includes a clamping cylinder 431 and a clamping block 432 mounted on the top surface of the piston rod of the clamping cylinder 431. The piston rod of the clamping block 432 extends towards the metal strip. The sliding seat 41, driven by the sliding drive 42, has a first working position and a second working position. When the sliding seat 41 is in the first working position, the clamping cylinder 431 drives the clamping block 432 to press down, thereby pressing the clamping block 432 against the top surface of the metal strip. When the sliding seat 41 is in the second working position, the clamping cylinder 431 drives the clamping block 432 to reset, so that there is a sliding gap between the clamping block 432 and the metal strip. During the transportation of the metal strip, through the abutting cooperation between the clamping block 432 and the metal strip, and the sliding drive 42 driving the sliding seat 41 to slide, the clamping member 43 drives the metal strip to move. In this embodiment, the sliding drive 42 is a sliding cylinder.

[0041] Reference Figure 2 and Figure 3To guide the sliding process of the sliding seat 41 and reduce the probability of the sliding seat 41 deviating during the sliding process, one side of the sliding seat 41 has a limiting part 412 protruding away from the sliding seat 41. The top surface of the frame 1 is provided with a limiting block 11, and the limiting block 11 has a sliding groove 111 for the limiting part 412 to slide. To further improve the sliding accuracy of the sliding seat 41, the top surface of the frame 1 is provided with a guide rail 12, and the sliding seat 41 has a guide groove 413 at the mounting through groove 411 that cooperates with the guide rail 12. Among them, in order to reduce the probability of the guide rail 12 interfering with the clamping fit between the clamping member 43 and the metal strip, the piston rod of the clamping cylinder 431 is arranged vertically on the center line of the double-acting screw 321 of the limiting mechanism 3, and the center line of the double-acting screw 321 coincides with the center line of the metal strip. The guide rail 12 is offset from the center line of the double-acting screw 321. In this embodiment, the cross-section of the guide groove 413 is I-shaped, and both sides of the sliding seat 41 have limiting parts 412.

[0042] Reference Figure 5 The straightening assembly 2 includes two opposing support plates 21 and two rotating shafts 22 rotatably connected to the support plates 21. The two rotating shafts 22 are arranged vertically at intervals along an axis perpendicular to the top surface of the frame 1, and a feeding gap 23 is provided between the two rotating shafts 22 for the metal strip to pass through. When the metal strip passes through the feeding gap 23, it can be straightened and leveled, making the surface of the metal strip smoother and providing better conditions for subsequent transportation.

[0043] Reference Figure 6 and Figure 7 To reduce the probability of unstable contact between the clamping part 43 and the metal strip due to wear on the top surface of the frame 1 corresponding to the bottom of the transport mechanism 4, a trapezoidal groove 13 is provided on the top surface of the frame 1. A mounting pad 14 is detachably installed in the trapezoidal groove 13, and the top surface of the mounting pad 14 is flush with the top surface of the frame 1. To ensure a stable fit between the mounting pad 14 and the trapezoidal groove 13, a mounting slider 141 is provided at the bottom of the mounting pad 14. A mounting groove 131 for arranging the mounting slider 141 is provided on the bottom surface of the trapezoidal groove 13, and a positioning groove 132 is provided at the mounting groove 131. The mounting slider 141 has a plunger hole 1411, and a ball-head spring plunger 1412 is provided in the plunger hole 1411. When the plunger ball 14121 of the ball-head spring plunger 1412 is engaged with the positioning groove 132, the mounting pad 14 is installed in the trapezoidal groove 13.

[0044] The implementation principle of a metal strip conveying device according to an embodiment of this application is as follows: During the transportation of the metal strip, the metal strip is first placed from the feeding gap 23 of the straightening component 2 onto the metal strip conveying device, and the metal strip is arranged at the bottom of the transportation mechanism 4. The pressing cylinder 431 drives the pressing block 432 to press down onto the top surface of the metal strip, and the sliding drive component 42 drives the sliding seat 41 to slide, thereby realizing the movement of the pressing block 432 and the metal strip. When the sliding seat 41 slides to the second station, the pressing cylinder 431 resets, and the sliding seat 41 resets to the first station. Through the continuous switching between the first station and the second station of the sliding seat 41, and the driving of the pressing cylinder 431, the transportation of the metal strip is realized. The setting of the limiting mechanism 3 ensures that the metal strip conveyed to the bottom of the transportation mechanism 4 can stably cooperate with the pressing component 43, ensuring the smooth transportation of the metal strip.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
