Detailed Description

The following detailed description of the embodiments of the present utility model is provided with reference to the accompanying drawings, so that the technical scheme of the present utility model is easier to understand and grasp, and the protection scope of the present utility model is defined more clearly.

The utility model designs and provides an automatic overturning mechanism for quality inspection of products of a photovoltaic production line, and aims to solve the problem of orientation positioning in quality inspection of the products. The general structural features are as shown in connection with fig. 1 to 4: the device mainly comprises a base bracket frame 1, a product carrier 2 and a rotating wheel unit 3. The base support frame 1 bears the integral support and stability guarantee of the automatic turnover mechanism, and the main body is a box-shaped frame body with a large opening, and is provided with a main support surface consisting of four bottom feet, one side upright rod and a side plate which are firmly supported. The illustration shows that the base support frame 1 is connected with a pair of parallel opposite and suspended

horizontal support arms

11 and 12 distributed along the length direction of the product based on upright posts at two sides, and each horizontal support arm end is embedded with a bearing part 13, and the axial directions of the two bearing parts are overlapped. The product carrier 2 is integrally formed into a rectangular frame with four assembled sides, and a pair of short frames 21 are respectively movably connected into the bearing parts 13 on the corresponding sides in a penetrating manner through the external rotating shaft 5, so that the product carrier is driven to axially and freely rotate around the rotating shaft based on the supporting and lubricating effects of the bearing parts. The pair of long frames 22 are connected with the short frames 21 at a lower height, the power wheel 6 and the supporting plate component 7 for clamping products are distributed on the opposite side surfaces of each long frame 22, the rotating wheel unit 3 is connected with a servo motor 31 on the base bracket frame, and an output wheel 311 of the servo motor 31 is connected with a driving gear 32 fixedly connected with a rotating shaft at one side in a transmission way through a belt wheel 33; the product carrier 2 is driven to controllably overturn and position at an angle in the base bracket frame 1; and as can be seen in fig. 2, the wheel unit is also provided with a safe, dust-proof, noise-reducing housing 34.

From the structural solution outlined above, it can be understood without doubt that: the design of the automatic turnover mechanism is initially designed to meet the requirement that the photovoltaic module needs to be manually and visually inspected for product quality after a certain part of manufacturing processes are completed. Therefore, the device mainly comprises a product carrier for driving product feeding, clamping and positioning and blanking and two parts of components for respectively supporting the product carrier and rotating in a controllable angle range from the aspect of functional design. Here, this product carrier is driven by servo motor and the drive unit that the output is controllable, and the inefficiency operation of upset, location is carried out to the experience to traditional manpower instead, and the clamping effect of product in the carrier is reliable, and the frame specification of batch product generally possesses the uniformity. Therefore, the tangential distance between the supporting plate component and the power wheel can be adjusted by fixing the size of the outer frame of the product before detection, so that the product is kept from unexpected displacement in the overturning process. Regarding the realization of the functions of product loading, unloading and clamping of the product carrier, the dependent structure is as follows: the long frame is internally provided with a closed-loop transmission chain driven by a material loading motor, and the plurality of power wheels are connected and driven by the transmission chain to rotate; the supporting plate component 7 is a plurality of driven pinch rollers which are arranged at the top side of the power wheel at intervals and are positioned with adjustable height. After the interval between the power wheel and the driven pinch roller is once set according to the appearance of the batch products, the product feeding is supported by the power wheel after contacting the first power wheel, and the product feeding is horizontally fed at the bottom side of the supporting plate component in one period and is positioned in or separated from the rectangular frame body of the product carrier. During the period, the surface of the product frame is reliably attached by the driven pressing wheel, and the distance between the pair of long frames is matched with the width specification of the product, so that the product is reliably clamped when being turned over during quality inspection, and displacement relative to the product carrier is not easy to occur.

As can be seen in further detail in connection with the embodiment shown in fig. 1 and 3, the product carrier 2 is provided with a guide ring 8 attached to the short frame 21 on the side close to the pulley 33. One radial central axis of the guide ring 8 coincides with the short frame, and both ends of the short frame are attached and fixed to the guide ring by hinge clips, respectively, and integrally follow up as shown in the figure. Namely, when the manual operation guide ring axially rotates, the short frame can also rotate in a clockwise direction; when the short frame is driven by external force to rotate around the rotating shaft, the guide ring also rotates. Based on the relative fixation of the horizontal supporting arms 12 and the flexible rotation of the short frame 21, a positioning guide post (not shown) axially parallel to the rotating shaft can be optionally arranged on the adjacent horizontal supporting arms 12, and the guiding ring keeps contact with the positioning guide post and slides along with the turnover of the product carrier. The arrangement can improve the stability of the guide ring for correcting the rotation of the product carrier through the axial positioning of the bearing part to the rotating shaft and the distance between the rotating shaft and the positioning guide post, and avoid the noise generated by eccentric rotation.

As further optimization, because the overall weight of the product carrier is large after the product carrier of the photovoltaic module is loaded in the product carrier, the influence of inertia can not be ignored when the product carrier is rotated and positioned by means of the output power of the servo motor. Relatively perfect control measures need to be designed to ensure the stability of rotation and positioning of the product carrier. Firstly, a limiting arm rod 81 is optionally sleeved and fixed on the guide ring 8 (the limiting arm rod and the guide ring are combined into a whole, and no relative displacement occurs under the action of external force after the assembly is completed), so that the product carrier 2 can be abutted against the horizontal supporting arm 12 to stop the overturning action of the product carrier under the state that the overturning of the product carrier reaches the inclination angle required by quality inspection.

Secondly, a tensioning wheel 34 with adjustable positioning is arranged on the horizontal supporting arm 12 at one side close to the belt wheel 33, and the tensioning wheel is internally tangent to the belt wheel to keep driving force; therefore, the output power of the servo motor can be reliably transmitted, and the inertia effect of the product carrier is buffered and restrained.

In addition, as can be seen from fig. 2, after the photovoltaic module product flows into the product stage, the long frame 22 is combined with the short frame and the lower side of the plane where the rotating shaft is located. The driving force of the integral overturning is severely fluctuated, and the output control of the servo motor is not facilitated, and the service life of the servo motor is prolonged. Therefore, the gravity balance needs to be performed on the two sides of the plane where the short frames and the rotating shaft are located, so the top surfaces of the pair of short frames 21 are connected with the balancing weights 9, the quality of the balancing weights is matched with the total weight of the long frames and the carried products, and therefore the driving force output by the servo motor can enable the product carrier to turn over and keep stable.

In summary, the utility model has the following essential characteristics and improvements as the description of the automatic turnover mechanism and the functional details based on the embodiment: the automatic overturning device is suitable for continuous product output production lines to carry out high-efficiency product overturning operation with consistent angle height, and combines a servo motor and a limit arm lever electromechanical integrated control means, so that each time of product loading can be accurately and quickly overturned to a required angle, and quality inspection effects are improved.

In addition to the above embodiments, other embodiments of the present utility model are possible, and all technical solutions formed by equivalent substitution or equivalent transformation are within the scope of the present utility model as claimed.
