Description

Technical Field

[0001] This utility model relates to the field of quality inspection technology, and in particular to a photovoltaic frame inspection rotating mechanism and a photovoltaic frame inspection device using the mechanism. Background Technology

[0002] After the photovoltaic frame is processed, it still needs to undergo quality inspection. The traditional inspection method is manual inspection. However, the accuracy of manual inspection is insufficient and it is easily affected by subjective errors. It is difficult to accurately identify minor defects such as hole spacing, length and hole diameter of the photovoltaic frame, which can easily lead to quality problems. At the same time, the traditional manual inspection mode is inefficient and costly. In the current context of the photovoltaic industry facing a "winter period" of supply and demand mismatch, overcapacity and price crash, it is no longer able to meet the urgent needs of enterprises to reduce costs and increase efficiency.

[0003] Currently, although automated inspection equipment capable of 24-hour unmanned inspection has emerged, the four sides of the photovoltaic frame, the 45° angles on both sides, and the groove in the middle all need to be inspected. This makes it difficult for the camera on the automated inspection equipment to take pictures, hindering accurate inspection. Therefore, some equipment manufacturers have added a flipping mechanism to their automated inspection equipment for photovoltaic frames. This flipping mechanism can use gravity to flip the photovoltaic frame. Specifically, a lifting cylinder pushes one side of the photovoltaic frame to achieve a 90° flip, and then another set of cylinders with contouring fixtures rises and supports the photovoltaic frame before the camera starts taking pictures. This solves the problem of the camera on the automated inspection equipment being unable to take pictures of the photovoltaic frame from multiple sides and angles.

[0004] However, the angle of this flipping mechanism varies slightly each time, and there are also cases where the flipping is not complete, causing the contouring fixture to fail to hold the photovoltaic frame. In addition, if a photovoltaic frame of a different size is used for testing, the contouring fixture needs to be replaced accordingly and the equipment needs to be readjusted, resulting in poor testing compatibility. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a photovoltaic frame detection rotation mechanism and detection device that can solve the problem of difficulty in taking photos from multiple angles and from multiple perspectives, and facilitate the detection of photovoltaic frames of different sizes.

[0006] The present invention adopts the following technical solution:

[0007] This utility model provides a photovoltaic frame detection rotation mechanism, including a control module. Two control modules are arranged symmetrically and spaced apart in the horizontal direction on a horizontal plane. Each control module includes a correction mechanism, a rotation drive mechanism, a buffer limit mechanism, and a controller. The correction mechanism is fixedly arranged, and the rotation drive mechanism is arranged above the correction mechanism and can move linearly in the horizontal direction on the horizontal plane under the drive of the correction mechanism. The buffer limit mechanism is connected to the rotation drive mechanism and can rotate under the drive of the rotation drive mechanism. Both the correction mechanism and the rotation drive mechanism are signal connected to the controller. The buffer limit mechanisms on the two control modules can respectively abut against both ends of the photovoltaic frame in the length direction.

[0008] Preferably, the correction mechanism includes a servo motor, a ball screw assembly, and a protective housing. The servo motor is axially connected to the screw on the ball screw assembly, and both the servo motor and the screw are located inside the protective housing. The nut seat on the ball screw assembly extends out of the protective housing and is connected to the rotary drive mechanism above. The servo motor is connected to the controller signal.

[0009] Preferably, the rotary drive mechanism includes a gear and rack assembly and a linear drive sub-mechanism. The rack on the gear and rack assembly is positioned above the linear drive sub-mechanism, and the linear drive sub-mechanism can drive the rack to move linearly in the longitudinal direction of the horizontal plane. Multiple rotatable gears are arranged parallel to each other on the mounting bracket of the gear and rack assembly. Each gear is axially connected to a buffer limiting mechanism and meshes with the rack. The mounting bracket is fixedly set. The linear drive sub-mechanism is positioned above the alignment mechanism, and the linear drive sub-mechanism can move linearly in the transverse direction of the horizontal plane under the drive of the alignment mechanism. The linear drive sub-mechanism is signal-connected to the controller.

[0010] Preferably, the linear drive submechanism includes a linear drive motor, a ball screw assembly, and a housing. The linear drive motor is axially connected to the screw on the ball screw assembly, and both the linear drive motor and the screw are located inside the housing. The nut seat on the ball screw assembly extends out of the housing and is connected to the rack above it. The linear drive motor is connected to the controller signal.

[0011] Preferably, the buffer limiting mechanism includes an abutment plate and a stop plate. Multiple connecting shafts are fixedly threaded through the abutment plate, and the stop plate is installed on the multiple connecting shafts for limiting. A spring is threaded through each connecting shaft, and the two ends of the spring abut against the abutment plate and the stop plate axially, respectively. The stop plate is connected to a rotary drive mechanism, and the stop plate can rotate under the drive of the rotary drive mechanism.

[0012] Preferably, the outer surface of the abutment plate is provided with a contour groove, which can match one end of the photovoltaic frame along its length.

[0013] This utility model also provides a photovoltaic frame detection device, including a scanning camera and a photovoltaic frame detection rotating mechanism as described above. The scanning camera is fixed directly above the photovoltaic frame detection rotating mechanism and is signal-connected to the controller.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] This utility model's photovoltaic frame detection rotating mechanism, in use, first moves the alignment mechanisms on the two control modules laterally in the horizontal plane. Then, the buffer limiting mechanisms on the two control modules move closer together to clamp the photovoltaic frame delivered to the middle position of the mechanism. Finally, the control rotation drive mechanism drives the buffer limiting mechanisms on the two control modules to rotate synchronously and stop at any position, thus solving the problem of difficulty in taking photos from multiple angles and from multiple perspectives. Furthermore, since the distance between the buffer limiting mechanisms on the two control modules is adjustable, it can accommodate photovoltaic frames of different sizes and lengths, facilitating the detection of photovoltaic frames of different dimensions.

[0016] The photovoltaic frame detection device of this utility model, by adopting the aforementioned photovoltaic frame detection rotation mechanism, can naturally allow the photovoltaic frame to rotate arbitrarily within 360° and stop at any position when the scanning camera position is fixed, so that the scanning camera can take pictures; in addition, it can also make the detection device compatible with photovoltaic frames of different sizes and lengths.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0034] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0035] See Figure 1 and Figure 2This embodiment provides a photovoltaic frame detection rotation mechanism, including a control module A. Two control modules A are spaced apart and symmetrically arranged in the horizontal direction of the horizontal plane. The control module A includes a correction mechanism 1, a rotation drive mechanism 2, a buffer limit mechanism 3, and a controller. The correction mechanism 1 is fixedly arranged, and the rotation drive mechanism 2 is arranged above the correction mechanism 1. The rotation drive mechanism 2 can move linearly in the horizontal direction of the horizontal plane under the drive of the correction mechanism 1. The buffer limit mechanism 3 is connected to the rotation drive mechanism 2 and can rotate under the drive of the rotation drive mechanism 2. Both the correction mechanism 1 and the rotation drive mechanism 2 are signal connected to the controller. The buffer limit mechanisms 3 on the two control modules A can respectively abut against the two ends of the photovoltaic frame B in the length direction.

[0036] In this embodiment, the photovoltaic frame detection rotation mechanism first moves the alignment mechanism 1 on the two control modules A laterally in the horizontal plane. Then, the buffer limiting mechanisms 3 on the two control modules A move closer together to clamp the photovoltaic frame B, which is transported to the middle position of the mechanism. Finally, the control rotation drive mechanism 2 drives the buffer limiting mechanisms 3 on the two control modules A to rotate synchronously and stop at any position, thus solving the problem of difficulty in taking photos from multiple angles and perspectives. Furthermore, since the distance between the buffer limiting mechanisms 3 on the two control modules A is adjustable, it can accommodate photovoltaic frames B of different sizes and lengths, facilitating the detection of photovoltaic frames B of different dimensions.

[0037] Better yet, see Figure 1 In this embodiment, the control module A also includes a receiving box 4 with a bottom opening. The rotary drive mechanism 2 and the buffer limiting mechanism 3 are both disposed in the receiving box 4, and the rotary drive mechanism 2 is connected to the correction mechanism 1 through the bottom opening of the receiving box 4.

[0038] Preferably, in this embodiment, the controller is a PLC controller.

[0039] Preferably, the correction mechanism 1 includes a servo motor, a ball screw assembly, and a protective housing. The servo motor is axially connected to the screw on the ball screw assembly, and both the servo motor and the screw are located inside the protective housing. The nut seat on the ball screw assembly extends out of the protective housing and is connected to the rotary drive mechanism 2 above. The servo motor is connected to the controller signal.

[0040] The alignment mechanism 1 can drive the lead screw on the ball screw assembly to rotate via a servo motor, thereby driving the nut seat screwed on the lead screw to move linearly. In addition, the rotary drive mechanism 2 is connected to the nut seat, so the distance between the buffer limit mechanisms 3 on the two control modules A can be controlled, so as to achieve the purpose of clamping and aligning the photovoltaic frame B by the alignment mechanism 1 and being compatible with photovoltaic frames B of different lengths and sizes.

[0041] Preferably, see Figures 2 to 4 The rotary drive mechanism 2 includes a gear and rack assembly and a linear drive sub-mechanism 201. The rack 202 on the gear and rack assembly is positioned above the linear drive sub-mechanism 201, and the linear drive sub-mechanism 201 can drive the rack 202 to move linearly in the longitudinal direction of the horizontal plane. Multiple rotatable gears 204 are arranged parallel to each other on the mounting bracket 203 of the gear and rack assembly. Each gear 204 is axially connected to a buffer limiting mechanism 3 and meshes with the rack 202. The mounting bracket 203 is fixedly set. The linear drive sub-mechanism 201 is positioned above the alignment mechanism 1, and the linear drive sub-mechanism 201 can move linearly in the transverse direction of the horizontal plane under the drive of the alignment mechanism 1. The linear drive sub-mechanism 201 is connected to the controller signal.

[0042] The linear drive submechanism 201 can push the rack 202 to move linearly in the longitudinal direction of the horizontal plane, thereby driving multiple gears 204 on the mounting bracket 203 to rotate synchronously. As a result, the buffer limiting mechanism 3, which is axially connected to the gears 204, can rotate synchronously, thereby allowing the photovoltaic frame B in the clamped and aligned state to rotate at any angle, which is convenient for camera to take pictures and detect.

[0043] Better yet, see Figure 4 In this embodiment, eight rotatable gears 204 are arranged parallel to each other on the mounting bracket 203.

[0044] Preferably, the linear drive submechanism 201 includes a linear drive motor, a ball screw assembly, and a housing. The linear drive motor is axially connected to the screw on the ball screw assembly, and both the linear drive motor and the screw are located inside the housing. The nut seat on the ball screw assembly extends out of the housing and is connected to the rack 202 above it. The linear drive motor is signal-connected to the controller.

[0045] Similar to the aforementioned correction mechanism 1, the linear drive submechanism 201 can drive the lead screw on the ball screw assembly to rotate via a linear drive motor, and the nut seat is screwed onto the lead screw, thereby enabling linear movement under the drive of the lead screw, and thus achieving the purpose of linear movement of the rack 202 in the longitudinal direction of the horizontal plane.

[0046] Preferably, see Figure 5The buffer limiting mechanism 3 includes an abutment plate 301 and a baffle plate 302. Multiple connecting shafts 303 are fixedly threaded through the abutment plate 301. The baffle plate 302 is mounted on the multiple connecting shafts 303 for limiting their movement. Each connecting shaft 303 is equipped with a spring 304, the two ends of which abut against the abutment plate 301 and the baffle plate 302 axially. The baffle plate 302 is connected to the rotary drive mechanism 2 and can rotate under the drive of the rotary drive mechanism 2. The presence of the springs 304 on the connecting shafts 303 allows the buffer limiting mechanism 3 to clamp and straighten the photovoltaic frame B while simultaneously providing buffering, preventing damage to both ends of the photovoltaic frame B along its length.

[0047] Preferably, see Figure 5 The outer surface of the abutment plate 301 is provided with a contour groove 305, which can cooperate with one end of the photovoltaic frame B along its length. The contour groove 305 on the abutment plate 301 enables the buffer limiting mechanism 3 to clamp and align the photovoltaic frame B more stably.

[0048] This embodiment also provides a photovoltaic frame detection device, including a scanning camera and the aforementioned photovoltaic frame detection rotating mechanism. The scanning camera is fixed directly above the photovoltaic frame detection rotating mechanism and is signal-connected to the controller.

[0049] The photovoltaic frame detection device of this embodiment, by employing the aforementioned photovoltaic frame detection rotation mechanism, can naturally allow the photovoltaic frame to rotate arbitrarily within 360° and stop at any position when the scanning camera position is fixed, so that the scanning camera can take pictures. In addition, the detection device can also be compatible with photovoltaic frames of different sizes and lengths.

[0050] 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 substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
