[0066] Next, the present invention will be further described in conjunction with the accompanying drawings.

[0067] As Figures 1 to 8As shown in the figure, a preparation process of a solar module with high conversion efficiency provided by this embodiment includes the following steps:

[0068] Step 1: Laminate the backsheet 11, the lower encapsulant film 12, the solar cells 13, the lower encapsulant film 14, and the front glass 15 that make up the solar module in sequence. The solar cells are connected by interconnection bars to form a battery string group, and every two groups of battery string groups are connected by busbars;

[0069] Step 2: Transport the solar module to the framing unit, and complete the framing of the solar module through the framing unit and fix it with corner locks;

[0070] Step 3: Manually install the junction box and test.

[0071] The working principle and beneficial effects of the above technical solution are as follows:

[0072] The present invention discloses a preparation process of a solar module with high conversion efficiency. The backsheet 11, the lower encapsulant film 12, the solar cells 13, the lower encapsulant film 14, and the front glass 15 are laminated in sequence to form the solar module. The solar cells are connected by interconnection bars to form a battery string group, and every two groups of battery string groups are connected by busbars, thereby improving the conversion efficiency. The solar module is transported to the framing unit, and the framing unit is used to replace manual installation, improving the framing efficiency.

[0073] In one embodiment, the interconnection bar adopts a structure with round wires close to the front of the solar cell 13 and flat shape close to the back of the solar cell 13.

[0074] In one embodiment, the size of the solar cell 13 is 185.3mm * 182mm.

[0075] In one embodiment, the lower encapsulant film 12 is an EVA encapsulant film.

[0076] In one embodiment, the framing unit in Step 2 includes:

[0077] A frame conveying unit 21, the frame conveying unit 21 includes four frame conveying channels 22 arranged in parallel on a frame conveying base 20, wherein the two middle frame conveying channels 22 are used to convey long frames 23, and the two frame conveying channels 22 on both sides are used to convey short frames 24;

[0078] A frame correction unit 25, the frame correction unit 25 is installed on the frame conveying base 20, and the frame correction unit 25 is used to correct the conveying direction of the frame;

[0079] A frame installation unit 26, the frame installation unit 26 is used to grab the long frames 23 and short frames 24, and assemble the long frames 23 and short frames 24 into a square frame body.

[0080] The working principle and beneficial effects of the above technical solution are as follows:

[0081] The long side frames 23 are conveyed through the two middle side frame conveying channels 22, and the short side frames 24 are conveyed through the side frame conveying channels 22 on both sides. The side frame correction unit 25 corrects the side frames conveyed in the side frame conveying channels 22, so that the side frames in the conveying process are corrected. After the long side frames 23 and the short side frames 24 dock at the designated positions of the side frame conveying unit 21, the side frame installation unit 26 grabs the long side frames 23 and the short side frames 24 and assembles the long side frames 23 and the short side frames 24 into a square frame body.

[0082] In one embodiment, the side frame installation unit 26 includes:

[0083] An upper transverse beam, which is erected at a preset position. An upper transverse component is installed on the upper transverse beam, and a lower lifting component is installed at the bottom end of the upper transverse component;

[0084] An upper mounting seat 31, which is installed on the lower lifting component through a support frame;

[0085] A rotating seat 32, which is embedded at the bottom end of the upper mounting seat 31;

[0086] A short side frame grabbing component 33, which is installed on the rotating seat 32;

[0087] A driving motor 39, which is installed at the top end of the upper mounting seat 31 and is used to drive the rotating seat 32 and the short side frame grabbing component 33 to act synchronously;

[0088] Two action chambers two 27 are symmetrically arranged in the upper mounting seat 31 with the rotating seat 32 as the center. A chute two communicating with the action chambers two 27 is opened at the bottom end of the upper mounting seat 31;

[0089] A motor one 28, which is installed in the action chambers two 27. A screw two 29 is installed at the output end of the motor one 28. A screw block two 20 slidably connected in the chute two is sleeved on the screw two 29, and a suction cup two is installed at the bottom end of the screw block two 20.

[0090] The working principle and beneficial effects of the above technical solution are as follows:

[0091] When the upper transverse movement component works and drives the upper mounting seat 31 to move along the upper transverse beam to a preset position, the lower lifting component works, driving the upper mounting seat 31 to descend. Then, the short frame gripping component 33 and the second suction cup complete the gripping of the long frame 23 and the short frame 24. After the gripping is completed, while the lower lifting component drives the upper mounting seat 31 to rise, the drive motor 39 works, driving the rotating seat 32 to rotate at the bottom end of the upper mounting seat 31. When the rotating seat 32 completes a 90° rotation, it drives the two long frames 23 to rotate 90°. The motor one 28 in the operation chamber two 27 rotates, driving the screw two 29 installed at the output end of the motor one 28 to rotate. The screw two 29 drives the screw block two 20 sleeved on it to slide along the chute two, thereby driving the two short frames 24 to move away from each other. In this way, when the two long frames 23 rotate 90°, the two long frames 23 move away from each other synchronously. And because the two short frames 24 move away from each other briefly, the avoidance of the long frame 23 is completed. After the two long frames 23 complete a 90° rotation, the two long frames 23 expand. At this time, the two short frames 24 reset, so that the two long frames 23 and the two short frames 24 are assembled into a square frame body.

[0092] In one embodiment, the short frame gripping component 33 includes:

[0093] The operation chamber one 34, which is arranged in the rotating seat 32;

[0094] The first helical gear 35, which is connected to the inner top of the operation chamber one 34 through a mounting shaft. Two second helical gears 36 are meshed with the first helical gear 35 and symmetrically installed in the operation chamber one 34. The output end of the drive motor 39 is installed with a central rotating shaft 30, and the central rotating shaft 30 extends into and is connected to the inner bottom of the operation chamber one 34. The central rotating shaft 30 penetrates the mounting shaft;

[0095] The screw one 37, two screw ones 37 are symmetrically installed in the operation chamber one 34 and are respectively connected to the second helical gears 36;

[0096] The screw block one 38, the bottom end of the rotating seat 32 is symmetrically installed with a chute one. The bottom end of the chute one communicates with the inside of the operation chamber one 34. The screw block one 38 is sleeved on the screw one 37 and is slidably connected in the chute one. The bottom end of the screw block one 38 is installed with a first suction cup.

[0097] The working principle and beneficial effects of the above technical solution are:

[0098] The driving motor 39 drives the rotating seat 32 to rotate 90° at the bottom end of the mounting seat 31 through the central rotating shaft 30. At this time, due to the cooperation of the first bevel gear 35 and the second bevel gear 36, the screw rod 37 connected to the second bevel gear 36 is driven to rotate in the first action chamber 34. The screw rod 37 drives the screw block 38 sleeved thereon to slide along the first chute, thereby driving the suction cup 38 connected to the screw block 38 to rotate. The suction cup 38 grabs the long side frame 23. In this way, while the two long side frames 23 are opened, they rotate 90°.

[0099] In one embodiment, the frame correction unit 25 includes:

[0100] A vertical rod 41, at the bottom end of the vertical rod 41, a nut fixing seat is installed, and the nut fixing seat is connected to the frame conveying base 20;

[0101] A supporting cross plate 42, the supporting cross plate 42 is installed at the top end of the vertical rod 41. A transverse movement chute is provided on the supporting cross plate 42, and a housing 44 is installed on the supporting cross plate 42;

[0102] A transverse movement slider 43, the transverse movement slider 43 is slidably connected to the transverse movement chute;

[0103] A turntable 45, the turntable 45 is installed at the inner top of the housing 44 through a reset rotating shaft, and a reset torsion spring is sleeved on the reset rotating shaft;

[0104] An eccentric rotating shaft 46, the eccentric rotating shaft 46 is eccentrically installed on the turntable 45;

[0105] A transverse movement frame body 47, the eccentric rotating shaft 46 is slidably connected to the transverse movement frame body 47, and the transverse movement frame body 47 is connected to the transverse movement slider 43 through a transverse movement slide rod 48;

[0106] A detection rod 49, the detection rod 49 is vertically bent, the detection rod 49 is located below the supporting cross plate 42 and is connected to the transverse movement slider 43, and the detection rod 49 is used to abut against the side end of the frame;

[0109] The working principle and beneficial effects of the above technical solution are:

[0110] The frame straightening unit 25 is installed on the frame conveying base 20 through a nut fixing seat, so as to facilitate the adjustment of the position of the frame straightening unit 25. The frame conveying channel 22 conveys the frame (including the long frame 23 and the short frame 24). At this time, the horizontal section of the detection rod 49 is attached to the side end of the frame. When the rear end of the frame tilts towards the horizontal section of the detection rod 49, the side end of the frame abuts against the horizontal section of the detection rod 49. The detection rod 49 drives the transverse sliding block 43 to slide in the transverse sliding groove, thereby driving the transverse sliding rod 48 connected to the transverse sliding block 43 and the transverse frame body 47 connected to the transverse sliding rod 48 to move horizontally towards the vertical rod 41. While the transverse frame body 47 drives the turntable 45 to rotate around the reset rotating shaft through the eccentric rotating shaft 46, the vertical section of the detection rod 49 drives the lifting assembly to work. The suction cup 40 adsorbs the top of the frame, and the lifting assembly drives the correction block assembly to work. The correction block assembly presses the frame away from the end of the detection rod 49, so that the frame rotates around the suction cup 40 to complete the straightening of the frame. When the frame straightening is completed, the frame disengages from the abutment against the horizontal section of the detection rod 49. At this time, under the action of the reset torsion spring, the reset rotating shaft connected to the reset torsion spring and the turntable 45 connected to the reset rotating shaft are reset in the housing 44. The eccentric rotating shaft 46 on the turntable 45 drives the transverse sliding rod 48, the transverse sliding block 43 connected to the transverse sliding rod 48, and the detection rod 49 connected to the transverse sliding block 43 to continue to move towards the frame direction.

[0111] In one embodiment, the lifting assembly includes:

[0112] The guiding vertical rods 51, two of the guiding vertical rods 51 are vertically installed at the bottom end of the supporting transverse plate 42;

[0116] The lifting sleeve 55, the lifting sleeve 55 is installed on the sliding plate 52 through a supporting vertical plate, and the correction block assembly is connected to the lifting sleeve 55;

[0117] The central lifting rod 56, the central lifting rod 56 is installed at the bottom end of the lifting sleeve 55, the third suction cup 40 is installed at the bottom end of the central lifting rod 56, both ends of the second spring are connected with spring mounting ears, one of the spring mounting ears is connected to the central lifting rod 56, and the other spring mounting ear is connected to the supporting vertical plate;

[0118] Gear 57 and rope reel one, the gear 57 and the rope reel one are coaxially installed at the bottom end of the support cross plate 42, the gear 57 meshes with the transverse movement rack 58, and the transverse movement rack 58 is installed on the detection rod 49;

[0119] Connecting rope one 59, the connecting rope one 59 passes through the rope wheel one 50 and is then connected between the rope reel one and the sliding plate 52, and the rope wheel one 50 is installed at the bottom end of the support cross plate 42.

[0120] The working principle and beneficial effects of the above technical solution are as follows:

[0121] The vertical section of the detection rod 49 drives the gear 57 to rotate through the transverse movement rack 58, thereby driving the rope reel one coaxially installed with the gear 57 to rotate. The rope reel one releases the connecting rope 59, so that the sliding plate 52 moves along the guiding vertical rod 51 in the stretching direction of the spring one 54. While the sliding plate 52 descends, it drives the lifting sleeve 55 installed on the sliding plate 52 through the support vertical plate to descend. The lifting sleeve 55 drives the suction cup 40 to descend through the central lifting rod 56. After the suction cup 40 descends and adheres to the top end of the frame, the suction of the frame is completed.

[0122] In one embodiment, the correction block assembly includes:

[0123] Installation vertical cylinder 61, the installation vertical cylinder 61 is installed at the bottom end of the support cross plate 42;

[0124] Sliding vertical grooves, two of the sliding vertical grooves are oppositely penetrated on the installation vertical cylinder 61;

[0125] Rotating shaft mounting seat 62, the rotating shaft mounting seat 62 is slidably connected to the inside of the installation vertical cylinder 61 through a connecting spring;

[0126] Driving rotating shaft 63, the driving rotating shaft 63 is rotatably installed on the rotating shaft mounting seat 62, and both ends of the driving rotating shaft 63 penetrate through the sliding vertical grooves;

[0130] The working principle and beneficial effects of the above technical solution are as follows:

[0131] After the suction cup 40 sucks the top of the frame, the central lifting rod 56 is retracted into the lifting sleeve 55. As the lifting sleeve 55 continues to descend, the lifting sleeve 55 drives the rope reel two 64 to rotate through the connecting rope two 66. While the rope reel two drives the transmission rotating shaft 63 connected thereto to rotate on the rotating shaft mounting seat 62, the eccentric block 65 coaxially mounted on the transmission rotating shaft 63 with the rope reel two 64 rotates. The eccentric block 65 abuts against the bottom end of the support cross plate 42, thereby driving the rotating shaft mounting seat 62 to move in the installation vertical cylinder 61 in the direction of stretching the connecting spring. The rotating shaft mounting seat 62 drives the wedge-shaped correction block 69 to descend through the support vertical rod 68. The inclined end of the wedge-shaped correction block 69 presses against the end of the frame away from the detection rod 49, so that the frame rotates around the suction cup 40. In this way, when the frame deviates too much, the correction of the frame is completed.
