Description

Technical Field

[0001] This utility model relates to the field of sheet material conveying and positioning technology, and specifically to a positioning and calibration structure for sheet material conveying equipment. Background Technology

[0002] After photovoltaic cells are manufactured, their photoelectric conversion efficiency needs to be tested, and they are then graded based on their efficiency to ensure the uniformity of conversion efficiency among cells of the same grade. During the efficiency testing process, conveying equipment is used to transport the cells to various testing devices for testing. In addition, in existing technologies, to ensure the accuracy of the testing, visual inspection and dynamic calibration components are installed at the entry point of the testing devices. These components can calibrate the position of the cells based on the deviation detected by visual inspection, ensuring the accuracy of subsequent testing.

[0003] Currently, the utility model patent with announcement number CN218841009U discloses a dual-half-cell battery efficiency detection device. This patent, by setting an adjustment mechanism, can adjust the position of the battery cells in multiple directions from the X-axis, Y-axis, and Z-axis. It mainly uses a visual inspection camera to take pictures of the battery cells for inspection, and then calculates the coordinates that need to be adjusted based on the position of the pictures. Finally, the position of the battery cells is corrected by the response of the angle adjustment mechanism, the Z-axis adjustment mechanism, the Y-axis adjustment mechanism, and the X-axis adjustment mechanism, which facilitates subsequent inspection work.

[0004] In the above technical solution, after visual inspection to determine the deviation, the system performs calculations, and finally the adjustment mechanism corrects the battery cell. Although the accuracy of the correction can be guaranteed, it requires the cooperation of many components. Moreover, relying entirely on visual imaging detection is prone to deviations due to contamination on the recording surface or the battery cell, affecting the accuracy of positioning calibration. Based on this, this application provides a positioning calibration structure for a sheet conveying device to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides a positioning calibration structure for a sheet conveying device to solve the problem in the prior art that the positioning accuracy of battery cells is easily affected by external factors such as dirt when positioning and calibrating them.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a positioning and calibration structure for a sheet conveying device, including a bearing plate and two belt conveyors, the two belt conveyors being respectively located on the front and back of the bearing plate and being coaxially driven;

[0007] The outer side of the support plate is provided with a positioning component and a reference block for positioning and calibrating the sheet. The reference block is located at the tail end of the outer side of the support plate along the sheet conveying direction.

[0008] The positioning component includes a mounting plate located at the bottom of the support plate, a meshing transmission module rotatably connected to the mounting plate, and a servo motor with the meshing transmission module moving at the bottom of the mounting plate.

[0009] The meshing transmission module is provided with two sliding members that can move in opposite directions. The top of the sliding members is provided with a positioning member for positioning and pushing the sheet material. The positioning member is located on the outside of the belt conveyor.

[0010] The above technical solution enables the servo motor to drive the meshing transmission module to work, thereby causing the two sliding parts to drive the corresponding positioning parts to move in opposite directions, allowing the positioning parts to push and position the sheet material located between the tops of the two conveyor belts in opposite directions.

[0011] Based on the above technical solution, the present invention can be further improved as follows.

[0012] Furthermore, the meshing transmission module includes two central shafts rotatably connected to the top of the mounting plate via bearings, with synchronous pulleys sleeved on the outer side of the central shafts, and a synchronous belt meshing between the outer sides of the two synchronous pulleys;

[0013] The output shaft of the servo motor passes through the bottom of the mounting plate and is fixed to the bottom end of one of the central shafts.

[0014] The above technical solution enables the servo motor to drive the corresponding central shaft to rotate, and then completes the meshing transmission work through the cooperation of the synchronous pulley and the synchronous belt.

[0015] Furthermore, the sliding member includes a locking block disposed on the outside of the timing belt, with two locking blocks located on both sides of the timing belt, and a slider fixed on the locking block;

[0016] The top of the mounting plate is provided with two linear slide rails for guiding the two sliders to slide.

[0017] The above technical solution uses a synchronous belt to drive two locking blocks to move in opposite directions, thereby causing the slider to move linearly on the corresponding linear slide rail.

[0018] Furthermore, the positioning element includes a vertical block disposed on the slider and a mounting block fixed to the top of the vertical block.

[0019] The above technical solution allows the mounting block to extend to the outside of the conveyor belt.

[0020] Furthermore, the top of the mounting block is rotatably connected to several rollers via a pivot, and the rollers on the top of the same mounting block are arranged at equal intervals along a direction parallel to the bearing plate.

[0021] The above technical solution enables the rollers to position the sheet material in a direction parallel to the support plate.

[0022] Furthermore, the positions of the top rollers of the two mounting blocks correspond one-to-one, and the top of the timing belt and the middle of the rollers are located in the same horizontal plane.

[0023] The above technical solution allows the rollers on the top of the two mounting blocks to position and calibrate the sheet in a symmetrical manner.

[0024] Furthermore, two connecting posts are provided between the top of the mounting plate and the bottom of the bearing plate, and the two linear slide rails are respectively located on opposite sides of the two connecting posts.

[0025] The above technical solution enables the mounting plate to be installed normally on the bottom of the support plate.

[0026] Compared with the prior art, the technical solution of this application has the following beneficial technical effects:

[0027] 1. It can perform direct opposing positioning calibration after the sheet is moved to the designated position through a preset program; because the opposing positioning structure pushes the battery cell at the same time, the sheet can be quickly and stably positioned to the corresponding position, which is not easily affected by external factors such as dirt, and the error is about 3 microns, which facilitates accurate and stable subsequent testing.

[0028] 2. The overall structure is simple and uncomplicated, and it can meet the direct installation and use requirements of most conveying equipment, making it extremely versatile; it can be put into use simply by adjusting its preset parameters, making it highly practical.

[0038] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0040] Example: A positioning calibration structure for a sheet conveying device includes a support plate 1 and two belt conveyors 2, which are respectively located on the front and back of the support plate 1 and are coaxially driven. A positioning component 3 and a reference block 4 for positioning and calibrating the sheet are provided on the outside of the support plate 1. The reference block 4 is located at the tail end of the outside of the support plate 1 along the sheet conveying direction. The positioning component 3 includes a mounting plate 31 located at the bottom of the support plate 1. A meshing transmission module is rotatably connected to the mounting plate 31. A servo motor 35 with the meshing transmission module is located at the bottom of the mounting plate 31. The meshing transmission module is provided with two sliding members that can move in opposite directions. A positioning member for positioning and pushing the sheet is provided on the top of the sliding members. The positioning member is located on the outside of the belt conveyor 2.

[0041] It should be noted that the belt conveyor 2 is a conveying device driven by a motor, which is one of the most common conveying devices in the existing technology, so it will not be described in detail. The two belt conveyors 2 can run synchronously through coaxial transmission, thereby driving the sheet to move along the conveying direction, and the reference block 4 set on the bearing plate 1 abuts and limits the sheet.

[0042] It should also be noted that the servo motor 35 and the belt conveyor 2 are both electrically connected to the power supply and the main controller. The main controller can be a PLC controller, which can be implemented by simple programming by those skilled in the art. Moreover, the electrical connection technology is a publicly available technology, so it will not be described in detail.

[0043] refer to Figure 2 and Figure 3 The meshing transmission module includes two central shafts 32 rotatably connected to the top of the mounting plate 31 via bearings. Synchronous pulleys 33 are sleeved on the outer side of the central shafts 32, and a synchronous belt 34 meshes between the outer sides of the two synchronous pulleys 33. The output shaft of the servo motor 35 passes through the bottom of the mounting plate 31 and is fixed to the bottom end of one of the central shafts 32, so that the servo motor 35 can drive the corresponding central shaft 32 to rotate, thereby completing the meshing transmission work through the cooperation of the synchronous pulleys 33 and the synchronous belt 34.

[0044] It should be noted that the servo motor 35 has a high transmission accuracy, reaching about 1 micrometer. Synchronous pulleys 33 and synchronous belts 34 with different meshing accuracy are purchased according to actual needs; so that the overall error can be controlled to about 3 micrometers, with a maximum of no more than 6 micrometers, so that the positioning calibration work can be carried out accurately.

[0045] refer to Figure 3 and Figure 4 The sliding component includes a locking block 36 located on the outside of the timing belt 34. The two locking blocks 36 are located on both sides of the timing belt 34, and a slider 37 is fixed on the locking block 36. The top of the mounting plate 31 is provided with two linear slide rails 38 for guiding the two sliders 37 to slide. The timing belt 34 drives the two locking blocks 36 to move in opposite directions, thereby driving the sliders 37 to move linearly on the corresponding linear slide rails 38.

[0046] In use, the servo motor 35 drives the corresponding central shaft 32 to rotate. Under the meshing transmission of the synchronous belt 34 and the synchronous pulley 33, the two locking blocks 36 move in opposite directions, thereby driving the slider 37 to slide under the guidance of the linear slide rail 38.

[0047] refer to Figure 2 The positioning element includes a vertical block 51 disposed on the slider 37 and a mounting block 52 fixed to the top of the vertical block 51, which allows the mounting block 52 to extend to the outside of the belt conveyor 2.

[0048] refer to Figure 1 and Figure 2 The top of the mounting block 52 is rotatably connected to several rollers 53 via a pivot. The rollers 53 on the top of the same mounting block 52 are arranged at equal distances along a direction parallel to the support plate 1. Specifically, the top of the same mounting block 52 has three rollers 53, so that the rollers 53 can position the sheet material in a direction parallel to the support plate 1.

[0049] In use, the slider 37 drives the vertical block 51 and the mounting block 52 to move, thereby causing the rollers 53 on the top of the two mounting blocks 52 to move in opposite directions to position the sheet placed on the conveyor belt 2.

[0050] refer to Figure 1 and Figure 4 The positions of the top rollers 53 of the two mounting blocks 52 correspond one-to-one. The top of the timing belt 34 and the middle of the rollers 53 are located in the same horizontal plane, which allows the rollers 53 at the top of the two mounting blocks 52 to position and calibrate the sheet in a symmetrical position, thereby improving the stability of positioning.

[0051] refer to Figure 1 and Figure 2 Two connecting posts 6 are provided between the top of the mounting plate 31 and the bottom of the support plate 1. Two linear slide rails 38 are located on opposite sides of the two connecting posts 6, so that the mounting plate 31 can be installed normally on the bottom of the support plate 1, thereby allowing the positioning component 3 to operate normally.
