Description

Technical Field

[0001] This application relates to the field of photovoltaic cell technology, and in particular to a correction and adjustment mechanism. Background Technology

[0002] In the production process of solar modules, EVA films need to be precisely cut using a cutting machine and then laid on glass.

[0003] Due to the prevalent issues of low cutting and laying accuracy, and the difficulty in correcting material deviations during installation, material correction is necessary. Currently, the common method is to directly detect and correct deviations in the material (EVA film) during cutting and installation. However, this method provides slow feedback and cannot promptly correct the material's position and orientation, leading to EVA film misalignment or offset during installation, which severely impacts product yield. Utility Model Content

[0004] To solve the above-mentioned technical problems, one technical solution adopted in this application is:

[0005] A web-correction adjustment mechanism is provided, installed on an unwinding device to drive the overall movement of the unwinding device for web correction. The unwinding device performs unwinding transmission along the X-axis direction, causing the EVA film to be unloaded along the X-axis direction. The mechanism includes:

[0006] The base has at least one set of slide rails fixedly installed on it in the Y-axis direction. That is, the installation direction of the at least one set of slide rails is perpendicular to the transmission direction of the unwinding device, and the unwinding device is connected to the base through the at least one set of slide rails.

[0007] The adjustment drive assembly includes an electric cylinder, a hinge seat, and a fixing block. The fixing block is mounted on the base. The hinge seat is movably connected to at least one end of the electric cylinder's front and rear ends. At least one of the fixing block and the uncoiling device is movably connected to the electric cylinder via the hinge seat. Using a hinged connection reduces machining precision requirements, facilitates installation, and prevents jamming during movement (the electric cylinder pushing the uncoiling device may generate vibration, causing the electric cylinder to be subjected to a force pointing towards the base, potentially leading to eccentric damage). In the Y-axis direction, the electric cylinder extends and retracts to move the uncoiling device on the slide rail, allowing the uncoiling device to translate left and right relative to the base.

[0008] The correction sensor is fixedly connected to the mounting frame, which is installed at the discharge end of the uncoiling equipment, or on the cutting equipment / ground downstream of the uncoiling equipment, to ensure that the mounting frame does not move with the uncoiling equipment.

[0009] The correction sensor is used to detect the relative position of the material edge and the correction sensor in real time for correction feedback. The adjustment drive component drives the unwinding equipment to move according to the correction feedback from the correction sensor. The material correction adjustment is achieved by moving the unwinding equipment as a whole, thereby effectively improving the efficiency and accuracy of correction feedback and adjustment, and ensuring the accuracy of subsequent processing steps.

[0010] In a preferred embodiment of this application, a slider is fixedly connected to the bottom of the unwinding device, and the slider is slidably connected to the slide rail.

[0011] In a preferred embodiment of this application, the hinge seat is rotatably connected to the front end of the electric cylinder or the rear end housing, and the electric cylinder is movably connected to the fixed block or the uncoiling device via the hinge seat. When the electric cylinder is hinged at one end and fixed at the other, vibration may occur, so it is necessary to improve the processing accuracy.

[0012] In a preferred embodiment of this application, a hinge seat is connected to the front end of the electric cylinder and the rear end of the housing. The front end of the electric cylinder is movably connected to the unwinding device through the hinge seat, and the rear end of the electric cylinder is movably connected to the fixed block through the hinge seat. The use of a hinged structure at both ends can effectively improve the smoothness of equipment operation.

[0013] In a preferred embodiment of this application, the correction sensor is a U-shaped sensor, and the EVA film from the unwinding device passes through the U-shaped opening to determine whether to initiate correction adjustment by detecting the edge position of the EVA film.

[0014] In a preferred embodiment of this application, the mounting frame includes a fixed frame and an adjusting frame, the adjusting frame being rotatably connected to the fixed frame, and the correction sensor being detachably connected to the adjusting frame.

[0015] In a preferred embodiment of this application, the fixing frame and the adjusting frame are provided with connecting holes, and the locking screw passes through the connecting holes on the fixing frame and the adjusting frame and connects with the locking nut to lock the adjusting frame and the fixing frame.

[0016] In a preferred embodiment of this application, the adjustment frame is provided with a waist-shaped mounting hole, a fixing screw is movably connected to the mounting hole, one end of the fixing screw is fixedly connected to the correction sensor, and a fixing nut is movably connected to the other end. The correction sensor is connected to the adjustment frame through the fixing screw and the fixing nut.

[0017] A laying device includes an unwinding device, a cutting device, a laying device, and a correction and adjustment mechanism, wherein the correction and adjustment mechanism is any one of the correction and adjustment mechanisms described above.

[0018] The beneficial effects of this application are as follows: By detecting the position of the material through a correction sensor, the start and stop of the correction adjustment are controlled. The adjustment drive component drives the unwinding mechanism to move, and the correction is achieved by adjusting the overall position of the unwinding mechanism. This improves the accuracy and efficiency of the correction feedback and adjustment, thereby effectively improving the accuracy of subsequent cutting and laying, ensuring product yield, reducing material waste, and lowering costs. At the same time, the hinged installation method at both ends of the electric cylinder reduces processing precision, facilitates installation, prevents vibration from damaging the electric cylinder, and extends its service life.

[0024] The technical solutions in the embodiments of this application will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-4 The embodiments of this application include:

[0026] In solar module production, the components from bottom to top include glass, EVA film, electromagnetic sheet, and backsheet. The EVA film is used to cure the electromagnetic sheet and backsheet, eliminating pore gases. A laying device includes an unwinding device 10, a cutting device 20, and a laying device 30 arranged sequentially along the EVA film's transmission direction for production. The EVA film is unwound by the unwinding device, turning the EVA film roll into a thin film. Powered by a film power mechanism via a guide roller, the EVA film moves forward, passes through a pendulum tension mechanism, and then through a correction and adjustment mechanism before entering the cutting device.

[0027] An unwinding machine is a device that converts EVA film from roll material into flat film. It includes a frame and, mounted on the frame, an air shaft, a roll-turning mechanism, and a film power mechanism. The roll-turning mechanism is used to mount the EVA film roll and drive it to rotate. The air shaft is movably connected to the frame to support and tension the EVA film. The film power mechanism drives the drive shaft to rotate, thereby moving the EVA film forward. The unwinding machine performs unwinding transmission along the X-axis, causing the EVA film to be unloaded along the X-axis.

[0028] A correction adjustment mechanism drives the unwinding equipment 10 to move as a whole to perform correction. The structure includes: a base 1, an adjustment drive component 2, and a correction sensor 3.

[0029] In the Y-axis direction, two sets of slide rails 11 are fixedly installed on the base 1, and two sets of sliders 12 are correspondingly provided on the bottom of the unwinding device 10. The sliders 12 are slidably connected to the slide rails 11, so that the unwinding device 10 can move back and forth along the slide rails 11.

[0030] The adjustment drive assembly 2 includes an electric cylinder 21, a hinge seat 22, and a fixing block 23. The fixing block 23 is mounted on the base 1. A hinge seat 22 is connected to the front end of the electric cylinder 21 and the rear end of the housing. The front end of the electric cylinder 21 is movably connected to the uncoiling device 10 through the hinge seat 22. The rear end of the electric cylinder 21 is movably connected to the fixing block 23 through the hinge seat 22. The extension and retraction of the electric cylinder 21 drives the uncoiling device 10 to move on the slide rail 11, thereby causing the uncoiling device 10 to move horizontally relative to the base 1.

[0031] Since the vibration that may be generated when the electric cylinder 21 pushes the uncoiling device 10 to move can cause the electric cylinder 21 to be subjected to a force pointing in the direction of the base 1, which may cause the electric cylinder 21 to be damaged due to eccentricity, the electric cylinder 21 in this application adopts a hinged structure at both ends, which can not only reduce the processing precision and facilitate installation, but also prevent the generation of jamming during the movement, thus effectively improving the smoothness of equipment operation.

[0032] The correction sensor 3 is fixedly connected to the mounting bracket 4. The mounting bracket 4 does not move with the unwinding equipment 10. The mounting bracket 4 can be installed at the discharge end of the unwinding equipment 10, the cutting equipment 20 downstream of the unwinding equipment 10, or on the ground. The correction sensor 3 is a U-shaped sensor. The EVA film coming out of the unwinding equipment 10 passes through the U-shaped opening so that the sensor can detect the edge position of the film. While detecting, the sensor will transmit a feedback signal to the adjustment drive component 2 to determine whether to start correction based on the specific detection information. If correction needs to be started, the electric cylinder 21 will start and drive the unwinding equipment 10 to move, thereby ensuring that the edge of the EVA film is always in the center position of the correction sensor 3, which helps to improve the accuracy of subsequent cutting and laying.

[0033] Mounting bracket 4 includes a fixed bracket 41 and an adjusting bracket 42. The adjusting bracket 42 is detachably connected to the fixed bracket 41. The fixed bracket 41 and the adjusting bracket 42 are provided with connecting holes 45. According to the installation requirements, the connecting holes 45 on the fixed bracket 41 and the adjusting bracket 42 can be aligned. Then, the locking screw 43 passes through the connecting holes 45 on the fixed bracket 41 and the adjusting bracket 42 and is connected to the locking nut to lock the fixed bracket 41 and the adjusting bracket 42.

[0034] Furthermore, the fixed frame 41 may have only one connection hole 45, while the adjusting frame 42 may have two or more connection holes 45; or the fixed frame 41 may have two or more connection holes 45, while the adjusting frame 42 may have only one connection hole 45; or both the fixed frame 41 and the adjusting frame 42 may have two or more connection holes 45. This allows for adjustment not only of the connection angle between the fixed frame 41 and the adjusting frame 42, but also of the front-to-back position between the fixed frame 41 and the adjusting frame 42, meeting different usage requirements and facilitating precise adjustment of the position and angle of the correction sensor 3.

[0035] When adjusting the angle, first loosen the locking screw 43 and the locking nut so that the adjusting bracket 42 can rotate axially around the locking screw 43 to change the angle between the adjusting bracket 42 and the fixed bracket 41. After the angle is determined, tighten the locking nut 43 to lock the adjusting bracket 43 and the fixed bracket 41.

[0036] The adjustment frame 42 is provided with an oblong mounting hole 44. The fixing screw is movably connected to the mounting hole 44, and one end of the fixing screw is fixedly connected to the correction sensor 3, while the other end is threaded with a fixing nut. This allows the correction sensor 3 to be connected to the adjustment frame 42 through the fixing screw and the fixing nut, so as to fix the correction sensor 3 in a suitable position on the adjustment frame 42. In this way, the installation position of the correction sensor 3 can be adjusted according to the actual installation and use requirements to improve the accuracy of detection.

[0037] When adjusting the position of the correction sensor 3, first loosen the fixing nut so that the fixing screw can move back and forth along the waist-shaped mounting hole 44. When the correction sensor 3 moves to the target position, tighten the fixing nut to lock the position of the correction sensor 3.

[0038] The beneficial effects of the correction and adjustment mechanism proposed in this application are as follows: By detecting the relative position of the material edge and the sensor through a correction sensor, the start and stop of the correction and adjustment are controlled. The adjustment drive component drives the unwinding mechanism to move, and the correction is achieved by adjusting the overall position of the unwinding mechanism. This improves the accuracy and efficiency of the correction feedback and adjustment, thereby effectively improving the accuracy of subsequent cutting and laying, ensuring product yield, reducing material waste, and lowering costs. At the same time, the hinged installation method at both ends of the electric cylinder reduces processing precision, facilitates installation, prevents vibration from damaging the electric cylinder, and extends its service life.

[0039] The above description is merely an embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
