[0026]

[0027] ​The orthopedic wheel 40 comprises a roller sleeve IV 41, a roller shaft IV 42, a positioning groove II 43, and an orthopedic protrusion 44. The roller sleeve IV 41 is sleeved on the roller shaft IV 42 in a manner that the outer peripheral surface is parallel to the roller shaft IV 42; the positioning groove II 43 is opened on the outer peripheral surface of the roller sleeve IV 41 in a manner, for example, perpendicular to the outer peripheral surface of the roller sleeve IV 41 and terminates at the middle part extending towards the roller shaft IV 42, so that the positioning groove II 43 is formed as an inner groove on the roller sleeve IV 41; and the orthopedic protrusion 44 is perpendicular to the outer peripheral surface of the roller sleeve IV 41, and preferably the orthopedic protrusion 44 is integrated with the roller sleeve IV 41. The bracket II 45 is vertically connected to the roller shaft IV 42.

[0028] The photovoltaic frame comprises a C wall 51, a notch 52, an A surface 53, a B surface 54, and a D surface 55. The C wall 51 can be placed in the positioning groove I 23 of the positioning wheel I 20 and the positioning groove II 43 of the orthopedic wheel 40. The outer wall surfaces of the A surface 53, the B surface 54, and the C wall 51 are sequentially and adjacently connected, the D surface 55 is adjacently connected with the inner wall surface of the C wall 51, and the other end of the wall where the D surface 55 is located is separated from the groove wall where the A surface 53 is located to form the notch 52.

[0029] In combination Figure 5 As shown, the pressing and positioning wheel group comprising the pressing wheel I 10 and the positioning wheel I 20 is a conveying mechanism for the photovoltaic frame before sandblasting. The roller sleeve I 11 has two positioning protrusions I 13, and the distance between the two positioning protrusions I 13 is the same as the width of the B surface 54, which can play a positioning role. The roller sleeve II 21 has a positioning groove I 23, which can accommodate the C wall 51 of the photovoltaic frame, and can further play a positioning role.

[0030] In the pressing and positioning wheel group, the pressing wheel I 10 is arranged above the positioning wheel I 20 in a relative manner. Through the above-mentioned gap adjusting mechanism, the distance between the two wheels can be adjusted, and the pressing wheel I 10 mainly plays a role in pressing the B surface 54 of the profile and providing friction force for the profile to move forward. The roller shaft I 12 and the roller shaft II 22 rotate at the same speed and in opposite directions. Here, preferably, the outer peripheral surfaces of the roller sleeve II 21 and the roller sleeve IV 41 can appropriately form similar frictional contact with the top end of the groove wall where the D surface 55 or the A surface 53 is located.

[0031] The pressing and orthopedic wheel group comprising the pressing wheel II 30 and the orthopedic wheel 40 is a notch orthopedic and output conveying mechanism for the photovoltaic frame after sandblasting. As described above, the pressing and orthopedic wheel group is formed on the roller sleeve IV 41 corresponding to the roller sleeve II 21 and further has the orthopedic protrusion 44 for correcting the notch 52 on the basis of the same structure as the pressing and positioning wheel group.

[0032] More specifically, the roller sleeve III 31 has two positioning protrusions II 33, the distance between which is the same as the width of the B surface 54, and functions to position and correct. The roller sleeve IV 41 has a positioning groove II 43 and a correction protrusion 44, which respectively function to position the profile and correct the size of the notch 52. In the cross section of the correction protrusion 44, the upper part facing the notch 52 is a circular arc chamfer, and the lower part adjacent to the sleeve IV 41 is a rectangle. The circular arc chamfer can guide the profile to enter the notch 52 of the photovoltaic frame more easily at the beginning.

[0033] The pressure wheel II 30 is arranged opposite to the correction wheel 40, and can be raised and lowered through the above-mentioned gap adjustment mechanism. The distance between the two wheels can be adjusted, and mainly functions to press the B surface 54 of the profile and provide friction to make the profile advance. The roller shaft III 32 and the roller shaft IV 42 rotate at the same speed and in opposite directions.

[0034] Along the axial direction of the roller sleeve I 11 and the roller sleeve II 21, a plurality of pairs of positioning protrusions I 13 and corresponding positioning grooves I 23 can be arranged, thereby achieving the positioning and output functions for multiple profiles in parallel.

[0035] Along the axial direction of the roller shaft III 32 and the roller shaft IV 42, a plurality of pairs of positioning protrusions II 33 and corresponding positioning grooves II 43 and correction protrusions 44 can be arranged, thereby achieving the correction and output functions for multiple profiles in parallel.

[0036] In this way, for the width size of the notch 52 of the photovoltaic frame, the correction function can be exerted in time in the scene of sandblasting, and unnecessary losses can be recovered.

[0037] <Embodiment>

[0038] The material of the photovoltaic frame is taken as an example of 6061 aluminum alloy, the composition of which meets the national standard.

[0039] The first 1-2 groups of pressure correction wheels are arranged immediately after the position of the photovoltaic frame out of the sandblasting machine, and a plurality of pressure positioning wheel groups are arranged at other positions, i.e., before the photovoltaic frame enters the sandblasting machine and in the sandblasting machine. A plurality of pressure positioning wheel groups are also arranged after the pressure correction wheel groups. See the specific examples in the following table. Figure 5 .

[0040] The roller shaft I 12, the roller shaft II 22, the roller shaft III 32, and the roller shaft IV 42 are made of 304 stainless steel, and the outer diameter is 55 (+0.03) mm. The telescopic rod I 14 and the telescopic rod II 34 are pneumatic, and the descending speed is 10-12 mm / s. The contact force with the profile is 15-20 N.

The material of the positioning protrusions Ⅰ 13 and the positioning protrusions Ⅱ 33 is soft rubber, the width is 18(±0.03)mm, and the height is 13(±0.03)mm.

[0043] The orthopedic protrusion 44 is made of hard rubber. According to the required correction width, the size can be selected as needed. One of the selection requirements is: it is necessary to ensure that the correction is qualified, but it is not necessary to exceed too much, and the width of the orthopedic protrusion 44 can be: 6.5(-0,+0.02)mm, and the height is 5.2(±0.02)mm. The top is a circular arc chamfer with a radius of 6(±0.1)mm, which can play a guiding role, making it easier to initially enter the notch 52 of the photovoltaic frame.

[0044] The positioning groove Ⅰ 23 and the positioning groove Ⅱ 43 are 2.5(±0.01)mm wide and 36(±0.02)mm high.

[0045] The compression positioning wheel group composed of the compression wheel Ⅰ 10 and the positioning wheel Ⅰ 20 is mainly used as a feeding transmission mechanism. Among them, the roller sleeve Ⅰ 11 and the roller sleeve Ⅱ 21 have the same rotation speed of 20-22r / min, but the rotation directions are opposite.

[0046] As shown in Figure 1 , the compression orthopedic wheel group including the roller shaft Ⅲ 32 and the roller shaft Ⅳ 42 is a sandblasting output conveying mechanism; at the same time, it is also a key mechanism for correcting the notch 52. The orthopedic protrusion 44 passes through the notch 52, so that the notch 52 that exceeds the lower limit after sandblasting is expanded and corrected. The roller sleeve Ⅲ 31 and the roller sleeve Ⅳ 41 have the same rotation speed of 20-22r / min, but the rotation directions are opposite.
