Description

Technical Field

[0001] The present application relates to the field of photovoltaic cell production equipment, and specifically to a strip splicing mechanism. Background Art

[0002] After battery strings are laid out and busbars are welded, they are formed into a battery string group and placed on the glass sheet. To prevent the string spacing from shifting during glass sheet transport, strips of tape are typically applied between adjacent battery strings within the group. Furthermore, to prevent adhesive shortages at the backsheet lead holes during subsequent lamination of the battery string group, adhesive film sheets are installed at the busbar lead locations of the battery string group. The adhesive film sheets have through-holes for the busbar leads to extend through.

[0003] Before applying the strip segments or film sheets, the strips or films must be unwound from a roll, and then cut into strip segments or film sheets by a subsequent cutting device.

[0004] When the roll has finished unwinding, meaning it can no longer hold any more strips or films, a new roll must be replaced. The existing roll replacement method involves stopping the machine, manually removing the raw roll, installing a new roll in its place, and manually pulling the strips or films from the new roll over the guide wheels and into the cutting device for cutting. This existing roll replacement method requires the machine to be shut down before the rolls can be replaced, and the machine can only be restarted after all rolls have been replaced. This results in significant downtime and reduces production efficiency. Utility Model Content

[0019] In some embodiments, the first strip and the second strip are non-sticky at room temperature; the first connecting portion or the second connecting portion also includes a welding component, and when the first adsorption plate and the second adsorption plate move relative to each other, the welding component passes through the first adsorption plate or the second adsorption plate and heats the tail end of the first strip and the head end of the second strip so that the tail end of the first strip and the head end of the second strip are bonded together, or heats the tail end of the second strip and the head end of the first strip so that the tail end of the second strip and the head end of the first strip are bonded together.

[0020] For strips that are non-sticky at room temperature, a welding component is set up. When the first adsorption plate and the second adsorption plate press the tail end of the working film and the head end of the spare film, the welding component passes through the first adsorption plate or the second adsorption plate to heat the tail end of the working film and the head end of the spare film, so that the tail end of the working film and the head end of the spare film are bonded together after being heated.

[0043] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0044] As described in the background technology section, the existing roll changing method requires stopping the machine before changing the material roll, and the machine can only be started after all the rolls are replaced. The downtime is long, which reduces production efficiency.

[0045] To this end, the present application provides a strip splicing mechanism that can achieve rapid online replacement of material rolls, thereby improving production efficiency.

[0046] Figure 1 FIG. 1 shows a schematic structural diagram of a strip splicing mechanism in an embodiment of the present application. Figure 2 A structural schematic diagram of a strip splicing mechanism in another embodiment of the present application is shown.

[0047] like Figure 1 and Figure 2 As shown, the strip splicing mechanism in the embodiment of the present application includes a first installation roller 1, a second installation roller 2, a first splicing portion 3 and a second splicing portion 4, wherein:

[0048] The first mounting roller 1 is configured to mount a first material roll 100, which, when rotating, releases a first tape 101. The second mounting roller 2 is configured to mount a second material roll 200, which, when rotating, releases a second tape 201.

[0049] The first connecting portion 1 and the second connecting portion 2 are arranged opposite to each other. A connecting gap is provided between the first connecting portion 1 and the second connecting portion 2 for a working strip to pass through. The working strip is the first strip 101 or the second strip 202 .

[0050] When the working strip is the first strip 101, the second connecting portion 2 is configured to fix the head end of the second strip 201. The first connecting portion 1 is configured to fix the tail end of the first strip 101 when the first strip 101 is unwound. The first connecting portion 1 and the second connecting portion 2 are further configured to move relatively close to each other so as to connect the tail end of the first strip 101 to the head end of the second strip 102. Similarly, when the working strip is the second strip 201, the first connecting portion 1 is configured to fix the head end of the first strip 101. The second connecting portion 2 is configured to fix the tail end of the second strip 201 when the second strip 201 is unwound. The first connecting portion 1 and the second connecting portion 2 are further configured to move relatively close to each other so as to connect the tail end of the second strip 201 to the head end of the first strip 101.

[0051] The strip splicing mechanism in the embodiment of the present application is provided with two mounting rollers configured to install material rolls. When the material roll on one mounting roller provides the working strip, the material roll on the other mounting roller serves as a spare material roll. During the feeding process, one of the first splicing part 1 and the second splicing part 2 fixes the tail end of the spare strip, and the working strip passes through the splicing gap between the first splicing part 1 and the second splicing part 2. When the working strip is used up, the tail end of the working strip enters the splicing gap, and the other of the first splicing part 1 and the second splicing part 2 fixes the tail end of the working strip. Finally, the first splicing part 1 and the second splicing part 2 move relative to each other, so that the tail end of the working strip and the head end of the spare strip can be pressed and spliced ​​together, thereby completing the online rapid replacement of the material roll.

[0052] like Figure 1 and Figure 2As shown, optionally, the first connecting portion 3 includes a first driving member 31 and a first adsorption plate 32, the first adsorption plate 32 is connected to the driving end of the first driving member 31, the first adsorption plate 32 is configured to adsorb the head end or tail end of the first strip 101, and the first driving member 31 is configured to drive the first adsorption plate 32 to move toward or away from the second connecting portion 4. The second connecting portion 4 includes a second driving member 41 and a second adsorption plate 42, the second adsorption plate 42 is connected to the driving end of the second driving member 41, the second adsorption plate 42 is configured to adsorb the head end or tail end of the second strip 201, and the second driving member 41 is configured to drive the second adsorption plate 42 to move toward or away from the first connecting portion 3. When the first adsorption plate 32 and the second adsorption plate 42 are away from each other, a connecting gap is formed between the first adsorption plate 32 and the second adsorption plate 42. When the first adsorption plate 32 and the second adsorption plate 42 move relatively and approach each other, the tail end of the first strip 101 is connected to the head end of the second strip 201 , or the tail end of the second strip 201 is connected to the head end of the first strip 101 .

[0053] Optionally, the first strip 101 and the second strip 201 are adhesive at room temperature. Still taking the first strip 101 as the working strip and the second strip 201 as the standby strip as an example, the optional working process of the first connecting portion 1 and the second connecting portion 2 is as follows;

[0054] The first driving member 31 and the second driving member 41 cooperate to drive the first adsorption plate 32 and the second adsorption plate 42 to move away from each other, so that a continuous gap is formed between the first adsorption plate 32 and the second adsorption plate 42 .

[0055] The leading end of the second tape 201 is fixed to the second suction plate 42 by suction. When the first roll 100 has exhausted the first tape 101, the trailing end of the first tape 101 enters the splicing gap between the second suction plate 42 and the first suction plate 32. Simultaneously, the subsequent drive mechanism stops pulling the first tape 101, keeping the trailing end of the first tape 101 within the splicing gap.

[0056] Subsequently, the first driving member 31 drives the first adsorption plate 32 to move toward the second adsorption plate 42 , and the first adsorption plate 32 adsorbs the tail end of the first strip 101 . At the same time, the second driving member 41 drives the second adsorption plate 42 to move toward the first adsorption plate 32 .

[0057] Finally, the first adsorption plate 32 and the second adsorption plate 42 press the tail end of the first strip 101 and the head end of the second strip 201 tightly, so that the tail end of the first strip 101 and the head end of the second strip 201 are bonded together.

[0058] After the tail end of the first strip 101 is connected to the leading end of the second strip 201, the first and second drive members 31 and 41 cooperate to drive the first and second adsorption plates 32 and 42 away from each other, re-forming a splicing gap between the first and second adsorption plates 32 and 42. The subsequent drive mechanism continues pulling, and the second roll 200 is driven by the drive mechanism to release the working strip. At this time, the second strip 201 switches to the working strip.

[0059] At this time, the new first material roll 100 can be installed on the first installation roller 1, and the head end of the first strip 101 on the first material roll 100 can be pulled and adsorbed and fixed on the first adsorption plate 32, that is, the first strip 101 is switched to a spare strip.

[0060] By configuring the first connecting portion 3 and the second connecting portion 4 as suction plates driven by a driver, both the first connecting portion 3 and the second connecting portion 4 can suction and secure the tail end of the working strip or the head end of the backup strip. When the suction plates of the first connecting portion 3 and the second connecting portion 4 move toward each other, they fully compress the tail end of the working strip and the head end of the backup strip, ensuring a secure connection.

[0061] Optionally, the first tape 101 and the second tape 201 are non-sticky at room temperature. In order to connect the tail end of the working film pressed by the first adsorption plate 32 and the second adsorption plate 42 to the head end of the spare film.

[0062] In an optional embodiment, a heating element is provided on the first adsorption plate 32 or the second adsorption plate 42, and the heating element is, for example, a heating rod inserted into the first adsorption plate 32 or the second adsorption plate 42. When the first adsorption plate 32 and the second adsorption plate 42 move relative to each other and approach each other, the heating element heats the tail end of the first strip 101 and the head end of the second strip 201, so that the tail end of the first strip 101 and the head end of the second strip 201 are bonded together, or the heating element heats the tail end of the second strip 201 and the head end of the first strip 101, so that the tail end of the second strip 201 and the head end of the first strip 101 are bonded together.

[0063] like Figure 2 As shown, another optional embodiment is that the second connecting portion 4 further includes a welding component 43, and an escape channel is provided on the second adsorption plate 42. When the first adsorption plate 32 and the second adsorption plate 42 move relative to each other and approach each other, the welding component 43 passes through the escape channel on the second adsorption plate 42, heats the tail end of the first strip 101 and the head end of the second strip 201, so that the tail end of the first strip 101 and the head end of the second strip 201 are bonded together, or heats the tail end of the second strip 201 and the head end of the first strip 101, so that the tail end of the second strip 201 and the head end of the first strip 101 are bonded together.

[0064] Of course, the welding assembly can also be set in the first connecting portion 3. In this case, an avoidance channel is provided on the first adsorption plate 32. When the first adsorption plate 32 and the second adsorption plate 42 move relatively and approach each other, the welding assembly 43 passes through the avoidance channel on the first adsorption plate 32 and heats the tail end of the first strip 101 and the head end of the second strip 201 so that the tail end of the first strip 101 and the head end of the second strip 201 are bonded together, or heats the tail end of the second strip 201 and the head end of the first strip 101 so that the tail end of the second strip 201 and the head end of the first strip 101 are bonded together.

[0065] Optionally, the first material roll 100 is fixedly mounted on the first mounting roller 1. A first sensor is provided on the first mounting roller 1. When the first material roll 100 is unwound, the first mounting roller 1 stops rotating, triggering the first sensor to generate a first splicing signal. The first sensor transmits the first splicing signal to the subsequent drive mechanism, which stops driving the first strip 101, ensuring that the tail end of the first strip 101 remains within the splicing gap. The first splicing section 3 and the second splicing section 4 then splice the tail end of the first strip 101 to the leading end of the second strip 201.

[0066] Similarly, the second material roll 200 is fixedly mounted on the second mounting roller 2, which is equipped with a second sensor. When the second material roll 200 is unwound, the second mounting roller 2 stops rotating, triggering the second sensor to generate a second splicing signal. The second sensor transmits the second splicing signal to the subsequent drive mechanism, which stops driving the second belt 201, ensuring that the tail end of the second belt 201 remains within the splicing gap. The first splicing section 3 and the second splicing section 4 then splice the tail end of the second belt 201 to the leading end of the first belt 101.

[0067] like Figure 1 As shown, optionally, the first connecting portion 3 and the second connecting portion 4 are arranged opposite to each other in the horizontal direction, and the first installation roller 1 and the second installation roller 2 are arranged below the first connecting portion 3 and the second connecting portion 4. The strip connecting mechanism in the embodiment of the present application also includes a first turning roller 5 arranged above the first connecting portion 1 and the second connecting portion 2. The working strip is transported horizontally to the rear track after passing over the first turning roller 5 upward.

[0068] Optional, Figure 1 The strip splicing mechanism in this embodiment also includes a tensioning pulley and a second deflection roller (not shown). The tensioning pulley is located below the first and second deflection rollers 5. After the working strip passes over the first deflection roller 5, it passes downward over the tensioning pulley and upward over the second deflection roller before being conveyed horizontally to the rear track. The tensioning pulley is configured to move up and down under the pull of the working strip to tension the working strip.

[0069] For example, the tensioning wheel is installed in a vertically extending waist hole. When the working belt is released too quickly and becomes slack, the tensioning wheel slides downward along the waist hole under its own weight, tightening the working belt and ensuring smooth rearward conveyance. When the working belt is released too slowly, the working belt pulls upward on the tensioning wheel, which then slides upward along the waist hole, maintaining proper tension on the working belt and preventing it from stretching or breaking.

[0070] like Figure 2 As shown, optionally, the first connecting portion 3 and the second connecting portion 4 are arranged relative to each other in the vertical direction. The strip connecting mechanism in the embodiment of the present application also includes a first steering wheel 6, a tensioning wheel 7 and a second steering wheel 8 arranged at the rear of the first connecting portion 1 and the second connecting portion 4, wherein the tensioning wheel 7 is located below the first steering wheel 7 and the second steering wheel 8. After the working strip passes around the first steering wheel 6, it passes around the tensioning wheel 7 downward, and passes around the second steering wheel 8 upward and is transported to the rear track in the horizontal direction. The tensioning wheel 7 is configured to move up and down under the pulling of the working strip to tension the working strip. Similarly, the tensioning wheel 7 realizes the tensioning of the working strip, so that the working strip is transported to the rear track with an appropriate tension.

[0071] Optionally, a third sensor is provided on the tensioning wheel. When the first or second material roll 100, 200, has been unwound, the tensioning wheel descends to its lowest position under its own gravity, triggering the third sensor to generate a third splicing signal. The third sensor transmits the third splicing signal to the subsequent drive mechanism, which stops driving the tail end of the working strip, ensuring that the tail end of the working strip remains within the splicing gap. This allows the first splicing section 3 and the second splicing section 4 to smoothly splice the tail end of the working strip to the leading end of the backup strip.

[0072] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application. The scope of protection claimed in the present application is defined by the claims, not by the above description in the embodiments. Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
