Photovoltaic modules typically include a cell sheet, a glass plate, and an encapsulant layer arranged in a stack in that order. For example, some current photovoltaic modules include a first glass plate and a second glass plate which are oppositely arranged, and a battery piece and a bus bar which are arranged between the first glass plate and the second glass plate, wherein one end of the bus bar is connected with the battery piece, and the other end of the bus bar is connected with a junction box through a lead-out hole on the first glass plate to extend out and connect with an external load through the junction box to lead out electric energy generated by the photovoltaic module. After the battery pieces, the bus bars and other components are arranged according to the set positions, the battery pieces are packaged between the first glass plate and the second glass plate through packaging materials, and the bus bars are fixed in the center of the leading-out holes.

However, in the preparation process of the photovoltaic module, after the bus bar extends out of the lead-out hole, the bus bar is easy to shift in the lead-out hole, so that the bus bar deviates from the center of the lead-out hole or inclines, the bus bar is inaccurate in positioning, and the operation of subsequent processes is influenced.

Specifically, when the bus bar is deviated from the center of the lead-out hole, the gap between the bus bar and the hole wall of the lead-out hole is not uniform in each region in the circumferential direction of the lead-out hole, and the viscosity of the paste used in filling the lead-out hole with the UV paste at present is 1200mPa · s to 5500mPa · s, and there may be a case where a small gap cannot be filled, so that bubbles are generated, making it difficult for the UV paste to uniformly wrap the bus bar. Moreover, when the bus bar is inclined, the bus bar can shield the UV glue in the lead-out hole, so that the light curing process is affected, and the curing effect is poor.

In addition, since the connection holes of the junction box and the lead-out holes of the glass plate are correspondingly positioned, when the bus bar is deviated from the center of the lead-out hole, the bus bar is also deviated from the center of the connection hole of the junction box accordingly, which causes inconvenience in connection of the bus bar with the junction box.

In the prior art, in order to improve the positioning accuracy between the bus bar and the lead-out hole, the bus bar is positioned in a manual mode, but the probability of errors generated by manual positioning is higher, the manual positioning efficiency is lower, and the industrial production is not facilitated.

Based on the above consideration, in order to solve the problem that the bus bar is prone to deviate from the center of the lead-out hole or incline in the step of extending the bus bar out of the lead-out hole, so that the bus bar is inaccurate in positioning, through intensive research, the inventor designs a bus bar positioning mechanism, wherein an inclined or fallen bus bar is centered by a centering piece, and then the bus bar is fixed at the centered position by a positioning piece, so that the bus bar is accurately positioned, and the subsequent process is convenient to perform.

The avoidance driving cylinder 600 drives the second shaping driving cylinder 520 to move along the direction perpendicular to the surface of the base 100, so that when the shaping driving assembly is required to drive the shaping piece 300 to move, the avoidance driving cylinder 600 drives the second shaping driving cylinder 520 to move, the distance between the second clamping foot 320 and the base 100 is equal to the distance between the first clamping foot 310 and the base 100, the first clamping foot 310 and the second clamping foot 320 can be matched to clamp the bus bar 20, and the bus bar 20 is fixed at the position coinciding with the axis of the lead-out hole 11. After the bus bar 20 is positioned, the avoidance driving cylinder 600 drives the second shaping driving cylinder 520 to move, so that the second shaping driving cylinder 520 is partially or completely hidden in the avoidance port 110, and the second shaping driving cylinder 520 prevents the second driving cylinder 420 from moving in the vertical direction in the next positioning process of the bus bar 20.

Further, the design driving assembly further comprises a third design driving cylinder 530 and a fourth design driving cylinder 540, the third design driving cylinder 530 and the fourth design driving cylinder 540 are both arranged on the base 100, the first design driving cylinder 510 is connected to the driving end of the third design driving cylinder 530, the avoidance driving cylinder 600 is connected to the driving end of the fourth design driving cylinder 540, and the second design driving cylinder 520 is connected to the driving end of the avoidance driving cylinder 600. After the first clamping pin 310 is spaced by 0.5mm from the axis of the lead-out hole 11 and the second clamping pin 320 is spaced by 0.5mm from the axis of the lead-out hole 11, the third sizing driving cylinder 530 drives the first sizing driving cylinder 510 to move downward along the vertical direction so that the first clamping pin 310 is inserted into the lead-out hole 11, the fourth sizing driving cylinder 540 drives the second sizing driving cylinder 520 to move downward along the vertical direction so that the second clamping pin 320 is inserted into the lead-out hole 11, the insertion depth of the first clamping pin 310 and the second clamping pin 320 can be 3.3mm, the first sizing driving cylinder 510 and the second sizing driving cylinder 520 further drive the sizing element 300 to clamp the bus bar 20, the clamping force is greater than 0N and less than or equal to 10N, the clamping process is kept for 1s to 2s, and the positioning work of the bus bar 20 is completed. After the bus bar 20 is positioned, the first clamping leg 310 and the second clamping leg 320 move away from each other and then move upward to return to the initial position.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present application. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
