Description

Technical Field

[0001] This utility model relates to the field of component clamping and positioning technology, and in particular to a clamping and positioning component for transporting photovoltaic components. Background Technology

[0002] In the adhesive coating process for photovoltaic module frames, the clamping stability of the material conveying system directly affects the quality of the adhesive seam formation and the production cycle. Taking the technical solution described in patent document CN118577454A as an example, it uses a positioning baffle combined with pneumatic clamping rollers to limit the photovoltaic panel. However, in practical applications, the following technical defects have been found: the longitudinal positioning baffle of this device can only provide unidirectional constraint, and the clamping force formed by the pneumatic roller assembly is prone to torque imbalance when the adhesive coating roller is pressed down, causing the photovoltaic panel to undergo micro-displacement in the XY plane. This dynamic instability not only causes the adhesive layer thickness to fluctuate beyond the process requirement of ±0.2mm, but may also cause adhesive splashing due to vibration, resulting in surface defects. Therefore, it is necessary to clamp the photovoltaic components on a conveyor mechanism such as a belt to maintain the stability of the photovoltaic components. Utility Model Content

[0003] Purpose of the invention: In order to overcome the shortcomings of the existing technology, this utility model provides a clamping and positioning component for transporting photovoltaic components, which can reliably position and fix moving parts.

[0004] Technical solution: To achieve the above objectives, the present invention provides a clamping and positioning assembly for conveying photovoltaic components, comprising:

[0005] The longitudinally extending support rod has a second groove extending along its length on its front surface and a first groove parallel to the second groove on its back surface.

[0006] A pair of clamping units disposed on the support rod, each clamping unit comprising:

[0007] A base installed within the second slide groove, the base being adjustable in position and fixed relative to the second slide groove.

[0008] The main swing arm has a first pivot end and a second pivot end, the first pivot end being hinged to the base.

[0009] The auxiliary swing arm, one end of which is hinged to the second pivot end,

[0010] A sliding block is slidably disposed in the first sliding groove and hinged to the other end of the auxiliary swing arm. The sliding block is provided with a displacement control component.

[0011] Furthermore, the main swing arm is L-shaped and includes a first arm segment and a second arm segment that are perpendicular to each other. The end of the first arm segment forms the first pivot end, and the end of the second arm segment forms the second pivot end. The main swing arm has two states: a working unfolded position and a retracted folded position. When it is in the working unfolded position, the first arm segment extends perpendicular to the surface of the support rod. When it is in the retracted folded position, the extension direction of the first arm segment is parallel to the extension direction of the support rod.

[0012] Furthermore, a flexible protective layer is provided on the working surface of the second boom segment.

[0013] Furthermore, the base of at least one clamping unit is connected to a support rod via an elastic compensation mechanism, which includes:

[0014] Mounting bracket fixed to the support rod.

[0015] A guide shaft passes through the mounting base, and its front end is connected to the base.

[0016] A limiting baffle is provided at the tail end of the guide shaft.

[0017] A pressure spring is sleeved on the guide shaft, and the pressure spring is pre-compressed between the mounting base and the limiting baffle.

[0018] Furthermore, the cross-sectional shape of both the second and first slide grooves is "convex".

[0019] Beneficial Effects: This utility model's clamping and positioning assembly for transporting photovoltaic components, through the synergistic effect of a spatial folding mechanism and an elastic compensation system, ensures that the main swing arm does not extend beyond the front surface of the support rod at certain stages. During operation, the rigid support structure of the L-shaped main swing arm, combined with the elastic compensation mechanism, allows for a certain degree of deformation compensation while ensuring positioning accuracy, making it particularly suitable for clamping photovoltaic components with thermal expansion characteristics. The convex-shaped groove ensures stability during the adjustment process. Attached Figure Description

Detailed Implementation

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] like Figure 1 The photovoltaic component clamping and positioning assembly shown includes a longitudinally extending support rod 1. Its front surface has a second sliding groove 12 extending along its length, and its back surface has parallel first sliding grooves 11. A pair of clamping units 2 are symmetrically mounted on the support rod 1. The base 21 of each clamping unit 2 is slidably embedded in the second sliding groove 12 and fixed in position by locking bolts. An L-shaped main swing arm 22 is hinged to the base 21. This main swing arm consists of a first arm segment 221 and a second arm segment 222 that are perpendicular to each other. The end of the first arm segment 221 is rotatably connected to the base 21, and the end of the second arm segment 222 is hinged to one end of a secondary swing arm 23. The other end of the secondary swing arm 23 is connected to a sliding block 24, which is embedded in the first sliding groove 11 for guided sliding. The sliding block 24 is provided with a displacement control component 25, which can drive the sliding block 24 to translate.

[0028] In the working state, when the sliding block 24 moves along the first slide groove 11 under the action of external force, the main swing arm 22 can switch between the folded position and the unfolded position through the transmission of the auxiliary swing arm 23. Figure 1 As shown, when in the folded position, the first arm segment 221 of the main swing arm 22 extends parallel to the surface of the support rod 1. At this time, the entire main swing arm 22 does not extend beyond the front surface of the support rod 1. In actual use, many support rods 1 with clamping units 2 are mounted on a flat belt. When the flat belt circulates, it effectively reduces the longitudinal space requirement of the equipment during the return phase. When clamping operations are required, such as... Figure 2 and Figure 5As shown, the second arm segment 222 of the main swing arm 22 rises vertically to form a vertical clamping surface. The distance between the working surfaces of the second arm segments 222 of the two clamping units 2 can be adjusted according to the size of the photovoltaic component. The 4mm thick silicone protective layer with a Shore A hardness of 70A covers the surface of the second arm segment 222, preventing scratches on the surface of the photovoltaic component a. In this embodiment, the displacement control component 25 is a roller. By setting a guide rail to guide the roller, the position of the sliding block 24 can be changed, thereby changing the state of the main swing arm 22.

[0029] One of the clamping units 2 has a base 21 connected to a support rod 1 via an elastic compensation mechanism 3, such as... Figure 3 and Figure 4 As shown, the elastic compensation mechanism 3 includes a mounting base 31 fixed on the support rod 1. A guide shaft 32, whose front end is connected to the base 21, passes through the mounting base 31. A limiting baffle 33 is provided at the tail end of the guide shaft 32. A pressure spring 34 is sleeved on the guide shaft 32 and pre-pressed between the mounting base 31 and the limiting baffle 33. This design allows the clamping unit 2 to generate elastic displacement during clamping operations. When encountering dimensional tolerances or assembly deviations of photovoltaic components, the elastic deformation can automatically compensate for the gap and maintain the clamping force, preventing damage to the photovoltaic components.

[0030] The second slide groove 12 and the first slide groove 11 on the support rod 1 both adopt a convex cross-section design. This structure can ensure the smooth movement of the sliding block 24 and the base 21, and also prevent the parts from falling out.

[0031] This clamping and positioning assembly, through the synergy of a spatial folding mechanism and an elastic compensation system, ensures that the main swing arm 22 never extends beyond the front surface of the support rod 1 during transport. During operation, the rigid support structure of the L-shaped main swing arm 22, combined with the elastic compensation mechanism, allows for some deformation compensation while maintaining positioning accuracy, making it particularly suitable for clamping photovoltaic modules with thermal expansion characteristics. The convex-shaped groove ensures stability during the adjustment process.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
