Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component production equipment, in particular to an emergency locking mechanism and a welding strip processing line. Background Art

[0002] Photovoltaic panels are connected by cell strings, which are connected by cell cells. The current mainstream technology is to connect the cell cells and welding ribbons to each other, and the welding ribbons connect the front electrodes and back electrodes of adjacent cell cells.

[0003] When the soldering tape is prepared on the supply device, it needs to be pulled out from the soldering tape roll and then cut on the soldering tape processing line. After that, the soldering tape will be fed from the soldering tape roll to the tape making platform through a pressing mechanism. A heavy hammer is provided at the delivery end of the soldering tape roll to straighten the soldering tape.

[0004] If the welding strip processing line encounters unexpected situations such as power failure or gas failure during operation, the clamping mechanism will fail to fix the welding strip, and the welding strip will be pulled back to the side of the welding strip roll by the heavy hammer mechanism. If the welding strip is pulled back, it will be pulled out of the groove in the welding strip processing line. After the processing device is powered on again, the welding strips need to be manually re-inserted into the groove one by one. The insertion process is relatively cumbersome, which wastes processing time and reduces production efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0022] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0024] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0025] Under the existing technology, after the solder strip processing line is shut down, the holding mechanism will be directly closed, thereby losing its clamping ability. The heavy hammer will pull the solder strip inserted in the holding mechanism back onto the solder strip material roll. After restarting the machine, the solder strip needs to be reinserted into the holding mechanism, wasting production time and reducing efficiency.

[0026] In order to solve the above problems, Figures 1 to 3 As shown, the utility model provides an emergency locking mechanism, which includes a bottom plate 1, a driving block 2 and a mounting frame 3. A guide column 4 is installed on the lower side of the mounting frame 3. The guide column 4 is perpendicular to the surface of the welding strip. The driving block 2 is plugged into the lower side of the guide column 4. When the driving block 2 moves, the guide column 4 can control the moving direction of the driving block 2 to be perpendicular to the bottom plate 1. The mounting frame 3 and the driving block 2 are connected by a second spring 6. A pressing block 7 is installed on the lower side of the driving block 2. The pressing block 7 presses the welding strip onto the bottom plate 1, and an air chamber 11 is formed in the bottom plate 1. The air chamber 11 is connected to the air source through an electromagnetic valve. Raised portions are formed on both sides of the bottom plate 1. A sliding groove 12 is provided in the raised portions. The space inside the sliding groove 12 can be increased by setting the raised portions. It is also convenient for the machine tool to open the sliding groove 12 while ensuring that the bottom plate 1 has sufficient strength. Plug-in portions 23 are formed at both ends of the driving block 2. The plug-in portion 23 is plugged into the sliding groove 12. A rubber film 13 is laid at the bottom of the sliding groove 12. An inflation hole 14 is provided on the bottom plate 1 on the lower side of the rubber film 13. The inflation hole 14 is connected to the air chamber 11.

[0027] The welding strip processing line also includes a transition plate, a holding mechanism and a strip making platform. The welding strip passes through the transition plate, the emergency locking mechanism, the holding mechanism and the strip making platform in sequence. The transition plate pulls the welding strip into the holding mechanism, and the holding structure fixes the welding strip. Then the strip making platform cuts the welding strip. The welding strip processing line always remains in an open state during normal processing. At this time, the solenoid valve is in an open state, and the gas source and the air chamber 11 are in a connected state. The air chamber 11 is filled with high-pressure gas, which makes the adhesive film 13 bulge. The adhesive film 13 will push the driving block 2 and the guide column 4 upward to move relative to the mounting frame 3, which will cause the pressing block 7 to rise and separate the pressing block 7 from the welding strip. During the processing of the strip making platform, the welding strip will always be transported forward.

[0028] When an unexpected situation causes the welding tape processing line to be shut down, the solenoid valve will be closed, and the gas source will not be able to supply high-pressure gas to the air chamber 11. The adhesive film 13 will shrink and return to its initial state, and the driving block 2 will drive the guide column 4 to descend relative to the mounting frame 3. The driving block 2 drives the pressure block 7 to be pressed on the welding tape, so that the welding tape stops moving and the welding tape will not be drawn back to the side of the welding tape roll by the heavy hammer. After the welding tape processing line is restarted, there is no need to re-thread the welding tape, which saves traction time and improves processing efficiency.

[0029] A first through hole 21 is provided in the driving block 2, and a first spring 5 is inserted into the first through hole 21. A pressure block 7 is connected to the lower end of the first spring 5. The fitting angle between the pressure block 7 and the welding strip can be adjusted by the first spring 5. The adjustment is performed by the expansion and contraction of the first spring 5, so that the pressure block 7 and the welding strip can be fitted more closely, so that the welding strip can be crimped by the pressure block 7 to prevent the welding strip from being drawn back by a heavy hammer.

[0030] The same pressing block 7 is connected to two groups of first springs 5, and the two groups of first springs 5 ​​are distributed along the length direction of the welding strip. The crimping angle of the pressing block 7 can be adjusted more flexibly through the extension and contraction of the two groups of first springs 5, so that the pressing block 7 and the welding strip on the bottom plate 1 can fit tightly, so that the welding strip can be pressed by the pressing block 7 and cannot move.

[0031] A first nut 22 is screwed onto the top of the first through hole 21, and the top of the first spring 5 abuts against the bottom of the first nut 22. By unscrewing the first nut 22, the first spring 5 can be taken out from the upper side of the mounting frame 3, which is convenient for staff to replace and improves the convenience of maintenance.

[0032] The mounting frame 3 is provided with a second through hole 31 , and the second spring 6 is sleeved in the second through hole 31 . A second nut 32 is screwed on the top of the second through hole 31 , and the top of the second spring 6 abuts against the second nut 32 .

[0033] When the adhesive film 13 bulges, the second spring 6 is in a compressed state, the adhesive film 13 becomes flat, the second spring 6 recovers its original length, and the pressure block 7 is crimped onto the welding strip, so that the driving block 2 and the guide column 4 move upward. A second nut 32 is provided on the mounting frame 3. Unscrewing the second nut 32 also facilitates the extraction of the second spring 6 for replacement, thereby reducing the difficulty of maintenance and replacement, and facilitating the staff to repair and replace the emergency locking mechanism.

[0034] A thread is formed at the end of the guide column 4, and the guide column 4 is screwed into the drive block 2. The guide column 4 is inserted into the mounting hole on the mounting frame 3 and slides freely in the mounting hole, so that the drive block 2 can slide back and forth along the axis of the guide column 4, and finally the drive block 2 can move perpendicular to the base plate 1. The guide column 4 is connected to the drive block 2 by a thread, which is convenient for disassembly and replacement.

[0035] The mounting frame 3 is mounted on the base 8, and the base 8 is fixed to the mounting surface of the welding strip processing line. The emergency locking mechanism is erected to a certain height through the mounting frame 3 so that the welding strip can remain horizontal when passing through the emergency locking mechanism to avoid interference wear.

[0036] A limiting plate 9 is fixed on one side of the driving block 2, and an opening 91 is provided on the limiting plate 9, and the opening 91 is in the shape of a trumpet, and a limiting area 92 is formed at the bottom of the opening 91, and a welding strip is placed in the limiting area 92. The end of the welding strip can be placed in the limiting area 92 through the trumpet-shaped opening 91, and each limiting area 92 is docked with the pressing block 7 corresponding to the rear side. When the welding strip is inserted into the emergency locking mechanism, the limiting area 92 can limit the position of the welding strip, so that the pressing block 7 can be accurately pressed on the welding strip to avoid shaking left and right. At the same time, the trumpet-shaped opening 91 is also convenient for placing the welding strip into the limiting area 92, which is convenient for guiding.

[0037] A first limiting surface 121 is formed on the upper side of the internal cavity of the sliding groove 12. The first limiting surface 121 is arranged on both sides of the plug-in part 23. The two groups of first limiting surfaces 121 are trumpet-shaped. The cross-section of the plug-in part 23 is trapezoidal. The inclined surfaces on both sides of the plug-in part 23 are second limiting surfaces 231. The first limiting surface 121 can abut against the second limiting surface 231.

[0038] When the adhesive film 13 swells to a certain extent, the first limiting surface 121 and the second limiting surface 231 abut against each other, thereby preventing the inserting portion 23 from further moving upward, limiting further expansion of the adhesive film 13, and preventing the adhesive film 13 from bursting.

[0039] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the scope of protection of the claims of the present invention.
