Abstract
Description
Technical Field
[0001] The utility model relates to a battery string adhesive tape connecting mechanism, in particular to a battery string without a main grid back contact in the photovoltaic industry, which is used for connecting adhesive tapes between battery cells. Background Art
[0002] In the photovoltaic industry, the structure of a busbar-less back-contact cell string generally includes cell sheets, solder ribbons, and adhesive tape. The adhesive tape is bonded to the gap between the two cell sheets to cover the solder ribbons connecting the cell sheets, thereby keeping the overall color of the cell string consistent and improving the aesthetics of the cell string.
[0003] In existing production operations, due to the large demand for tape, the intervals between roll changes are short and the frequency is high, which often requires dedicated personnel to operate, resulting in high workload and high production costs. Utility Model Content
[0004] The utility model provides a photovoltaic cell string tape splicing mechanism, which aims to overcome the above-mentioned deficiencies in the prior art and achieve rapid splicing after the tape roll is used up.

When the first roll of tape is almost finished, the sticky side of the tape is attracted to the tape suction plate, while the non-sticky side of the second roll is attracted to the heated suction plate. Powered by a pneumatic cylinder, the cutter on the first roll extends forward, severing the nearly finished end of the first roll. When the second roll of tape is almost finished, the non-sticky side of the tape is attracted to the heated suction plate, while the sticky side of the third roll is attracted to the tape suction plate. The motion mechanism pushes the suction plates, causing the tapes to dock, and simultaneously the cutter on the other side is driven, severing the nearly finished end of the second roll.
[0006] Preferably, the cutter mechanism includes a cutter, a tape presser, and a presser stopper. A pair of tape pressers are positioned opposite each other on either side of the presser stopper, each with a cutter positioned on its outer side. The cutter and tape presser on the same side are mounted on the same slider, which is slidably connected to the same guide rail. A clearance slot corresponding to the cutter position is defined in the center of the presser stopper. During operation, the tape presser and the presser stopper hold the tape in place, and the cutter cuts off the end of the tape that is nearly exhausted.
[0007] Preferably, the splicing mechanism includes a tape adsorption plate, a heating adsorption plate, a heat shield, and a cylinder. A pair of cylinders are positioned opposite each other, with the output end of one cylinder connected to the tape adsorption plate. A connecting plate securely connects the tape adsorption plate to a cutter and a tape pressing head on one side. The output end of the other cylinder is sequentially connected to the heat shield and heating adsorption plate. A connecting plate securely connects the heat shield to a cutter and a tape pressing head on the other side. The tape adsorption plate is provided with adsorption holes and has a non-stick surface. During operation, the tape adsorption plate absorbs the tail of the first roll of tape, the heating adsorption plate presses the tape to activate its adhesiveness, causing the two sections of tape to adhere. Simultaneously, the heating adsorption plate absorbs the head of the second roll of welding tape. The heat shield prevents heat from being transferred to the drive mechanism.
[0008] The advantages of this utility model are: reasonable structural design, rapid replacement and automatic splicing of tape rolls are achieved, which can improve overall efficiency and save labor costs. During operation, there is ample time to set the next roll of tape while the previous roll of tape is being used. The roll setting is convenient and will not interfere with the tape roll in use during operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0013] The present invention will be further described in detail below with reference to the embodiments and specific implementation methods.
[0014] like Figure 1 As shown, a photovoltaic cell string tape splicing mechanism comprises a first tape roll 10, a second tape roll 20 and a tape splicing mechanism 30. The tape splicing mechanism 30 is located between the first tape roll 10 and the second tape roll 20. The first tape roll 10, the second tape roll 20 and the tape splicing mechanism 30 are respectively mounted on a first tape roll mounting plate 11, a splicing mechanism mounting plate 31 and a second tape roll mounting plate 21 which are connected in sequence. A loading and unloading pressure plate 12 is provided in the center of the first tape roll 10 and the second tape roll 20.
[0015] The tape splicing mechanism 30 includes a first pressure wheel 32, a second pressure wheel 33, a first rotating wheel 34, a second rotating wheel 35, a cutter mechanism 36 and a splicing mechanism 37. The first pressure wheel 32, the cutter mechanism 36, the splicing mechanism 37, the second pressure wheel 33, the second rotating wheel 35 and the first rotating wheel 34 are sequentially installed on the splicing mechanism mounting plate 31 from top to bottom. The tape unwound from the first tape roll 10 or the second tape roll 20 passes through the first pressure wheel 32, the second pressure wheel 33, the first rotating wheel 34 and the second rotating wheel 35 in sequence and then enters the external tape applying mechanism. The first rotating wheel 34 is connected to the mounting plate 31 by sliding up and down.
[0016] The cutter mechanism 36 includes a cutter 41, a tape pressure head 42, and a pressure head limiter 43. A pair of tape pressure heads 42 are positioned opposite each other on either side of the pressure head limiter 43, with a cutter 41 positioned on the outer side of each tape pressure head 42. The cutter 41 and tape pressure head 42 on the same side are mounted on the same slider, which is slidably connected to the same guide rail. A recess is defined in the center of the pressure head limiter 43, corresponding to the position of the cutter 41. During operation, the tape pressure heads 42 and pressure head limiter 43 press the tape, which is then cut by the cutter 41. This is used to cut off the end of the tape that is almost exhausted. A sensor can preferably be configured to detect the remaining amount of tape.
[0017] The splicing mechanism 37 includes a tape suction plate 44, a heating suction plate 45, a heat shield 46, and a cylinder 47. A pair of cylinders 47 are positioned opposite each other. The output end of one cylinder 47 is connected to the tape suction plate 44. A connecting plate securely connects the tape suction plate 44 to one side's cutter 41 and the tape pressing head 42. The output end of the other cylinder 47 is connected, in sequence, to the heat shield 46 and the heating suction plate 45. A connecting plate securely connects the other side's cutter 41 and the tape pressing head 42. The tape suction plate 44 is provided with suction holes and has a non-stick surface. During operation, the suction holes of the tape suction plate 44 attract the tail of the first roll of tape through a clamping mechanism. Since the tape requires a certain temperature to activate its adhesiveness, the heating suction plate 45 is required to press the tape to ensure the two sections adhere. The heating suction plate also has a suction function, attracting the head of the second roll of welding tape. The heat shield 46 prevents heat from being transferred to the drive mechanism.
[0018] During specific operation, when the first roll of tape is almost used up, the sticky side of the tape (the tape is sticky on one side) is adsorbed by the tape adsorption plate 44, and the non-sticky side of the head of the second roll of tape is adsorbed by the heated adsorption plate 45. The power here is provided by the cylinder 47 (not limited to the cylinder), and at the same time, the cutter 41 on the side of the first roll of tape is driven forward to cut off the end of the first roll of tape that is about to be used up.
[0019] When the second roll of tape is almost used up, the non-sticky side of the tape is adsorbed by the heated adsorption plate 45, and the sticky side of the head of the third roll of tape is adsorbed by the tape adsorption plate 44. The motion mechanism pushes the tape adsorption plate 44 to make the tapes dock, and at the same time, the cutter 41 on the other side is driven to cut off the end of the second roll of tape that is almost used up.
[0020] Repeat the above steps.
[0021] The specific process of coil replacement is: when the previous roll of tape is in use, the next roll of tape can be set (with sufficient time). Only the loading and unloading pressure plate 12 needs to be operated. The operation will not interfere with the tape roll in use, and the coil setting is convenient.
[0022] During the coil stretching process, the first rotating wheel 34 moves upward or downward, which can trigger the upper and lower limit switches that are preferably set, and control the on and off of the circuit to achieve linkage.
[0023] The components described above are all prior art, and those skilled in the art can use any model and existing design that can achieve their corresponding functions.
[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the creative concept of the present invention, which all fall within the scope of protection of the present invention.
