Description

Technical Field

[0001] The present invention belongs to the technical field of laminators, and particularly relates to an automatic cleaning and avoidance device for a laminator. Background Art

[0002] The characteristics of solar photovoltaic power generation as a clean and renewable energy source have been widely understood and accepted by people, and it will surely play an increasingly important role in future development, and will surely have good prospects and development. At present, photovoltaic power generation mainly uses crystalline silicon battery components to utilize light energy. As an essential key equipment in the production of solar cell components, the automation, stability, and continuity of the laminator are becoming increasingly important and valued in the current large-scale production mode. Especially for the entire automated battery component production line, the continuous stability of the laminator and its connectivity and non-interference with the front and rear section production lines play a key role. At the same time, because the battery components use high-temperature curing adhesive materials such as EVA as the main raw materials for encapsulating the battery components. During the entire encapsulation and curing process of the laminator, the adhesive material is melted, extruded and flowed, and then firmly encapsulated with the battery silicon wafers or other battery raw materials and the upper and lower protective materials after high-temperature curing to achieve the usage purposes and requirements. However, during the entire process, the adhesive materials such as EVA may overflow or occasionally their tiny particles are brought into the interior of the laminator, resulting in the contamination of the conveying cloth or belt of the components or the conveying components by EVA, and being brought into the working cavity of the laminator again during the conveying process with the recycling of the conveying cloth, causing the components to be contaminated or having indentations, increasing the cleaning difficulty of the subsequent production line equipment or downgrading the components for use and other adverse consequences.

[0003] Currently, the adopted conveying cloth cleaning devices all use a motor to drive the cleaning brush to rotate, and are pushed and pressed against the conveying cloth by cylinders fixed at both ends of the frame for cleaning. Because the current device uses a separate motor to drive the cleaning brush to rotate and is driven by cylinders to push and press against the conveying cloth to achieve cleaning. However, due to the actual characteristics of using a steel profile crossbeam to fix the conveying cloth and dragging it to rotate in a cycle during the conveying and cleaning process, it is necessary to avoid the crossbeam during the conveying and cleaning process. Therefore, in order to meet this requirement, it is necessary to additionally install a detection sensor to detect the position of the crossbeam and feedback it to the central control unit for the cylinder avoidance action. On the one hand, this device uses an independent motor and cylinder push, increasing the production material cost and labor cost. On the other hand, due to reasons such as multiple device action functions and large external interference, the detection of the conveying crossbeam is not timely, resulting in the crossbeam being hit or the cylinder not operating, etc., affecting the reliability and continuity of the device use and the production efficiency of the components. Summary of the Invention

[0004] The object of the present invention is to solve the above-mentioned drawbacks existing in the prior art, and to propose an automatic cleaning and avoiding device for a laminator. This device does not require a dedicated motor for driving the cleaning brush to be installed separately, nor does it require related components such as bilateral cylinders for avoiding and dragging the conveying cloth crossbeam and electrical switches for detecting the crossbeam. Therefore, on the one hand, the production cost is effectively saved, and on the other hand, vicious problems such as untimely avoidance caused by detection are eliminated. At the same time, since there are no components such as motors and cylinders, electrical energy and gas sources are no longer required accordingly, directly saving energy and increasing efficiency.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] Now, in conjunction with the accompanying drawings of the specification, the structural features of the present invention will be described in detail.

[0028] See Figure 1, An automatic cleaning and avoiding device for a laminator, comprising a bearing and fixing frame body 13, which is fixedly arranged on both sides of the equipment frame body. Linear sliding mechanisms are fixedly installed on the bearing and fixing frame bodies 13 on both sides. An avoiding plate 8 is fixedly installed at the free end of the linear sliding mechanism. The linear sliding mechanism includes a slider 14 and a slide rail 15. The slider 14 is slidably connected to the slide rail 15. The slide rail 15 is fixedly arranged on the bearing and fixing frame body 13. The avoiding plate 8 is fixedly installed on the slider 14. Under the action of the linear sliding mechanism, the avoiding plate 8 can slide on the bearing and fixing frame body 13.

[0029] See Figure 3-4 , On the side facing the conveying cloth 5 between the avoiding plates 8 on both sides, a cleaning brush 7 is fixedly installed. The cleaning brush 7 is arranged corresponding to the brush carrying roller 4. Self-cleaning brushes 72 are arranged on both sides of the cleaning brush 7. The self-cleaning brushes 72 are installed on the outer cover of the cleaning brush 7 in a detachable manner, and the brush surfaces of the self-cleaning brushes 72 are arranged staggered with the cleaning brush 7. When the cleaning brush 7 rotates, the self-cleaning brushes 72 will remove the foreign objects adhered to the cleaning brush 7.

[0030] See Figure 1 and 4 , An adjustable linear buffer mechanism is arranged between the avoiding plate 8 and the bearing and fixing frame body 13. The adjustable linear buffer mechanism includes a spring pressure rod 10 and a pressure spring 11 sleeved on the spring pressure rod 10. The two ends of the spring pressure rod 10 are respectively fixed on the avoiding plate 8 and the bearing and fixing frame body 13 through a front support ear 101 and a rear support ear 102. Position locking nuts 12 are arranged at both ends of the spring pressure rod 10. A pressure adjusting nut 9 for adjusting the pressure spring 11 is arranged on the side of the front support ear 101 away from the position locking nut 12. By adjusting the pre-tightening force of the pressure adjusting nut 9 and the pressure spring 11, the functions of brush position and pressure are realized. When the cross beam 6 on the conveying cloth 5 is transmitted to the position of the cleaning brush 7, the cross beam 6 will push the avoiding plate 8 to move for avoidance. When the cross beam 6 passes over the cleaning brush 7, the avoiding plate 8 will reset again under the action of the adjustable linear buffer mechanism, so that the cleaning brush 7 contacts the conveying cloth 5 and continues to clean the surface of the conveying cloth 5. The pressure spring 11 is used as the driving element for the expansion and contraction of the cleaning brush 7. Through the characteristics of the spring and the mutual relationship between the fixed avoiding plates 8 and the cross beam 6 fixed at both ends of the cleaning brush 7, the functions of automatically pressing and cleaning the conveying cloth 5, automatically avoiding the dragging cross beam 6, and automatically resetting the cleaning brush 7 are realized.

[0031] See Figure 1-2, the cleaning brush gear 71 at one end of the cleaning brush 7 is driven by a cleaning brush chain 3 connected to the driving roller 1. An intermediate idler 16 for supporting the cleaning brush chain 3 is provided on the bearing and fixing frame 13. The cleaning brush chain 3 forms a triangular structure under the support of the intermediate idler 16. The intermediate idler 16 is arranged on a tensioning mechanism. The tensioning mechanism includes a connecting seat 161, a sliding groove 162 and a tension spring 163. The intermediate idler 16 is fixedly arranged on the connecting seat 161. The sliding groove 162 is arranged on the bearing and fixing frame 13. The connecting seat 161 is slidably connected to the sliding groove 162. The two ends of the tension spring 163 are respectively fixed on the connecting seat 161 and the bearing and fixing frame 13. The function of changing the position of the cleaning brush chain 3 and adjusting the chain tension is realized through the intermediate idler 16. The main transmission mechanism system is directly used to drive the cleaning brush 7 to rotate and clean directly, and there is no need to separately equip a cleaning motor for driving.

[0032] See Figure 5 , specifically, during use, first, the driving roller 1 (or other driving sources) drives the driving conveyor chain 2 and the brush cleaning chain 3 to perform power transmission at the same time; the driving conveyor chain 2 drives the dragging cross beam 6 installed and fixed thereon, and then drives the conveyor cloth 5 on the fixed cross beam 6 to move in the direction of the cleaning brush 7 along with the driving conveyor chain 2; at the same time, the cleaning brush chain 3 drives the cleaning brush 7 to rotate synchronously for cleaning, and the intermediate idler 16 is used to make up for the change in the chain length caused by the change in the brush position; when the cross beam 6 drives the conveyor cloth 5 to move to the position of the cleaning brush 7, the cross beam 6 will directly contact the avoidance plate 8 first, and through physical action, it will force the slider 14 below the avoidance plate 8 to move backward on the slide rail 15, so as to realize the design of automatically avoiding the passage of the cross beam 6 without any other external devices; when the cross beam 6 runs away from the fixed avoidance plate 8 as a whole, the pressure spring 11 fixed on the spring pressing rod 10 will automatically return to the working position of the cleaning brush 7 by the spring force for automatic cleaning work; before work, by adjusting the locking position of the position locking nut 12, the close distance between the cleaning brush 7 and the brush bearing roller 4 is realized, so as to achieve the accuracy and adjustability of the contact position between the cleaning brush 7 and the conveyor cloth 6 during the rotation and cleaning process of the cleaning brush 7; in addition, after adjusting the position locking nut 12, by adjusting the pressure adjusting nut 9, the pressure of the brush on the conveyor cloth during cleaning is completed after the relative positions of the cleaning brush 7 and the brush bearing roller 4 are determined. Thus, the automatic cleaning of the brush on the conveyor cloth and the automatic and reliable avoidance function of the dragging cross beam can be well realized without adding additional power sources, detection elements and actuators.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
