Description

Technical Field

[0001] This invention belongs to the field of flexible photovoltaic panel assembly and conveying technology, specifically relating to the moving mechanism of optoelectronic components, and particularly to an SMT placement machine, a flexible photovoltaic panel conveying mechanism and its working method. Background Technology

[0002] In the production and assembly process of flexible photovoltaic panels, optoelectronic components (such as thin-film resistors, chip inductors, etc.) need to be precisely installed onto the flexible substrate.

[0003] In related technologies, components are held in rigid cassettes during conveyor belt transport. As the belt passes through the conveyor trough, frictional resistance can easily arise between the components and the side walls of the cassette, causing the components to become stuck and unable to move smoothly to the designated pick-up position. When the pick-up grippers forcibly grasp the stuck components, uneven force or excessive clamping force can easily cause the components to break, thus affecting placement accuracy and production efficiency.

[0004] Therefore, how to prevent components from getting stuck in the material tray of the material strip is a technical problem that urgently needs to be solved.

[0008] In one optional embodiment, the extrusion surface of the inclined extrusion block is inclined downward along the conveying direction of the conveying groove; Furthermore, the distance between the two inclined extrusion blocks is greater than the width of the material box.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] In this document, when it is mentioned that a first component is located on a second component, this can mean that the first component can be directly formed on the second component, or that a third component can be inserted between the first and second components. Furthermore, in the accompanying drawings, the thickness of components may be exaggerated or reduced for the purpose of effectively describing the technical content.

[0025] Research has revealed that when components are held in rigid cassettes during conveyor belt transport, frictional resistance can easily arise between the components and the side walls of the cassettes as the belt passes through the conveyor trough. This can cause the components to become stuck within the cassettes, preventing them from moving smoothly to the designated pick-up position. When the pick-up grippers forcefully grasp the stuck components, uneven force or excessive clamping force can easily cause the components to break, thus affecting placement accuracy and production efficiency.

[0026] Based on the above research, this disclosure provides an SMT placement machine, a flexible photovoltaic panel conveying mechanism and its working method. By setting a pressure plate 300 with inclined extrusion blocks 310 on the conveying groove 210 of the picking table 200, and setting deformable material 420 on the side wall of the material box 410 of the material belt 400, when the material belt 400 travels in the conveying groove 210, the inclined extrusion blocks 310 can gradually extrude the top surfaces of both sides of the material box 410 from both sides. The deformation of the deformable material 420 is used to smoothly and orderly expose the components 440 in the material box 410 to the picking position, eliminating the jamming phenomenon of components 440 in the material box 410. There is no need for picking claws to forcibly grab, reducing the breakage of components 440 caused by excessive or uneven clamping force.

[0027] The shortcomings of the above solutions are the result of the inventors' practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed by the present disclosure embodiments in this article should be considered as contributions made by the inventors during the development of the present disclosure embodiments.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0029] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please see Figure 1 and Figure 2This disclosure provides a flexible photovoltaic panel conveying mechanism, including: a winding assembly 100 for conveying a strip 400; a receiving platform 200 for receiving the strip 400; a conveying groove 210 is provided on the receiving platform 200; a pressure plate 300 is provided on the conveying groove 210; inclined extrusion blocks 310 are provided on both sides of the bottom surface of the pressure plate 300 along the conveying direction of the strip 400; the side wall of the material box 410 of the strip 400 is a deformable material 420; when the strip 400 is delivered from the conveying groove 210, the inclined extrusion blocks 310 extrude pressure on both sides of the strip 400, causing the material box 410 to deform under compression below the upper surface of the element 440 to expose the element 440.

[0031] By setting a pressure plate 300 with inclined extrusion blocks 310 on the conveying trough 210 of the material picking platform 200, and setting deformable material 420 on the side wall of the material box 410 of the material belt 400, the inclined extrusion blocks 310 can gradually extrude the top surfaces of both sides of the material box 410 when the material belt 400 moves in the conveying trough 210. The deformation of the deformable material 420 is used to smoothly and orderly expose the component 440 in the material box 410 to the picking position, eliminating the jamming phenomenon of the component 440 in the material box 410. There is no need for the picking claw to forcibly grab it, reducing the breakage of the component 440 caused by excessive or uneven clamping force.

[0032] Please see Figure 1 and Figure 2 The pressing surface of the inclined pressing block 310 is inclined downward along the conveying direction of the conveying groove 210; and the distance between the two inclined pressing blocks 310 is greater than the width of the material box 410.

[0033] By setting the extrusion surface of the inclined extrusion block 310 to be inclined downward along the conveying direction of the conveying trough 210, and making the distance between the two inclined extrusion blocks 310 greater than the width of the material box 410, the material box 410 is guided by the gradually converging extrusion surface when entering the conveying trough 210, thereby achieving progressive extrusion of the side wall of the material box 410 (e.g., ...). Figure 5 As shown), the height of the deformable material 420 is changed from... Figure 4 H1 is extruded into H2, where H1 > H2, and the height of the deformed material 420 is reduced, causing the element 440 to be exposed from the material box 410.

[0034] Please see Figure 2 and Figure 3 The two opposite side walls of the material box 410 extend inward to form horizontal blocking strips 430; the abutting surface 431 of the horizontal blocking strips 430 and the element 440 is inclined.

[0035] By extending horizontal blocking strips 430 inward from the two opposite side walls of the material box 410, and setting the abutment surface 431 of the horizontal blocking strips 430 and the element 440 to be inclined, the element 440 can be stably supported in the material box 410 by the horizontal blocking strips 430 when it is not squeezed.

[0036] The horizontal blocking strip 430 is disposed in the middle of the side wall of the material box 410; and the distance between the horizontal blocking strip 430 and the top of the material box 410, and the distance between the horizontal blocking strip 430 and the bottom of the material box 410, are both greater than the thickness of the component 440.

[0037] Specifically, before conveying component 440 from the material strip 400 to the conveyor trough 210, an external vision sensor 731 captures an image to obtain image information; the external control module detects the appearance integrity of component 440 based on the received image information from the vision sensor; if the appearance inspection result of component 440 is unqualified, the external pressing assembly 732 presses component 440 into the bottom wall of the material box 410, so that component 440 is pressed under the horizontal blocking strip 430 (e.g., Figure 6 ).

[0038] By setting the horizontal blocking strip 430 in the middle of the side wall of the material box 410, and ensuring that the distance between the horizontal blocking strip 430 and the top and bottom of the material box 410 is greater than the thickness of the component 440, and by pressing the component 440 under the horizontal blocking strip 430 when the appearance inspection result of the component 440 is unqualified (e.g. Figure 6 This enables online screening and rejection of defective components 440, preventing them from entering subsequent material handling and placement processes. Components 440 that pass the inspection do not trigger the pressing assembly 732, and the status at this time is as follows: Figure 4 As shown.

[0039] It should be noted that there are multiple conveying troughs 210; the multiple conveying troughs 210 are arranged side by side. By setting multiple side by side conveying troughs 210, the flexible photovoltaic panel conveying mechanism can simultaneously convey multiple material strips 400 and expose the components 440, which significantly improves the material supply efficiency per unit time.

[0040] Please see Figure 7This disclosure also provides an SMT placement machine for assembling flexible photovoltaic panels, comprising: a work platform 500; a moving mechanism 600 embedded in the work platform 500 and used for conveying a mounting substrate 610; a picking mechanism 700 disposed on the work platform 500 via a reciprocating moving component 710 and located above the mounting substrate 610; a flexible photovoltaic panel conveying mechanism as described above, disposed on the work platform 500 and located to the side of the mounting substrate 610; and a control module for controlling the picking mechanism 700 to pick up components 440 from the flexible photovoltaic panel conveying mechanism and mount them on a flexible base plate on the mounting substrate 610.

[0041] The material handling mechanism 700 includes: a sliding plate 720 disposed on the reciprocating moving assembly 710; and a material handling part 730 disposed on the sliding plate 720. The material handling part 730 includes: a vision sensor 731, a material handling gripper, and a pressing assembly 732. The control module is configured to control the pressing assembly 732 to complete the screening of the components 440 in the material strip 400 based on the detection result of the components 440 by the vision sensor 731, and to install the qualified components 440 on the flexible base plate of the mounting substrate 610 through the material handling gripper.

[0042] By integrating a vision sensor 731, a gripper, and a pressing assembly 732 into the material handling mechanism 700, and with the control module controlling the pressing assembly 732 to screen the components 440 within the material strip 400 based on the detection results of the vision sensor 731, online judgment and classification of the component 440 quality are achieved. Qualified components 440 are precisely gripped and mounted by the gripper, while unqualified components 440 are pressed into the bottom of the material box 410 by the pressing assembly 732, preventing unqualified components 440 from being mistakenly mounted onto the flexible base plate.

[0043] The control module is equipped with an image recognition algorithm to perform image recognition on images captured by the vision sensor 731.

[0044] Please see Figure 8 This disclosure also provides a working method for using the flexible photovoltaic panel conveying mechanism described above, the working method including: S110: The material strip 400 is conveyed by the winding assembly 100; S120: After the material belt 400 passes through the conveyor trough 210, the material belt 400 is squeezed by the inclined extrusion block 310; S130: Expose component 440 in material box 410.

[0045] Before the material belt 400 enters the conveying trough 210, the operation method of the flexible photovoltaic panel conveying mechanism further includes: Detection is performed using an external vision sensor 731; When the appearance inspection result of component 440 is unqualified, the component 440 is pressed into the bottom wall of the material box 410 by the external pressing assembly 732, so that the component 440 is pressed under the horizontal blocking strip 430.

[0046] The beneficial effects of this invention are that the SMT placement machine, flexible photovoltaic panel conveying mechanism and its working method are achieved by setting a pressure plate 300 with inclined extrusion blocks 310 on the conveying groove 210 of the picking table 200, and setting deformable material 420 on the side wall of the material box 410 of the material belt 400. When the material belt 400 travels in the conveying groove 210, the inclined extrusion blocks 310 can gradually extrude the top surfaces of both sides of the material box 410 from both sides. The deformation of the deformable material 420 is used to smoothly and orderly expose the components 440 in the material box 410 to the picking position, eliminating the jamming phenomenon of components 440 in the material box 410. There is no need for picking claws to forcibly grab, reducing the probability of component 440 breaking due to excessive or uneven clamping force.

[0047] In the description of the embodiments of the present invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0048] In the description of this invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as a second element, component, region, layer, or segment.

[0049] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.

[0050] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
