Description

Technical Field

[0001] This utility model relates to the field of welding strip handling equipment, and in particular to a welding strip positioning mechanism. Background Technology

[0002] Currently, the welding strips used in BC module string welding machines are all rectangular welding strips. The welding strips are mostly positioned by mechanical grippers that pull the welding strips and use the grooves of the grippers for mechanical positioning. The entire welding strip is then placed on a cutter for cutting. The cutter cuts the entire welding strip into several small segments, which are then picked up by mechanical grippers and placed directly onto the welding platform for welding.

[0003] Currently, in the above process, there is no welding strip positioning mechanism to assist after the cutter finishes cutting. This may cause the welding strip to shift during the handling process, thus affecting the welding effect of the welding strip.

[0004] Based on this, the present invention proposes a welding strip positioning mechanism to solve the problems mentioned above. Utility Model Content

[0026] The welding strip positioning mechanism of this utility model will now be described in more detail with reference to the schematic diagrams, which illustrate preferred embodiments of this utility model. It should be understood that those skilled in the art can modify the utility model described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being of general knowledge to those skilled in the art and is not intended to limit the utility model.

[0027] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer from the following description. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0028] like Figure 1 As shown in the figure, this utility model embodiment proposes a welding strip positioning mechanism, including a welding strip handling gripper 1, a visual positioning device (not shown in the figure), and an adjustment component 2.

[0029] Specifically, the welding strip handling gripper 1 is used to clamp and transport the welding strip; the visual positioning device is used to capture the position of the welding strip held by the welding strip handling gripper 1; the adjustment component 2 is connected to the welding strip handling gripper 1 and is used to adjust the position of the welding strip held by the welding strip handling gripper 1 in the horizontal XY axis direction according to the information collected by the visual positioning device.

[0030] In the above embodiment, the adjustment component 2 includes a first horizontal rail assembly and a second horizontal rail assembly; the first horizontal rail assembly and the second horizontal rail assembly are connected, and the first horizontal rail assembly and the second horizontal rail assembly are arranged along the horizontal X-axis direction and the horizontal Y-axis direction, respectively.

[0031] The first horizontal linear guide assembly includes a first linear screw guide 21 arranged in the horizontal X-axis direction and a first drive motor 22; the first drive motor 22 is mounted on the first linear screw guide 21 and is used to provide a power source for the operation of the first linear screw guide 21.

[0032] The second horizontal linear guide assembly includes a second linear screw guide 23 arranged in the horizontal Y-axis direction and a second drive motor 24; the second drive motor 24 is mounted on the second linear screw guide 23 and is used to provide a power source for the operation of the second linear screw guide 23.

[0033] Specifically, such as Figure 2As shown, the first linear screw guide rail 21 includes a first track component 212 on which a first drive screw 211 is rotatably mounted. The first track component 212 is arranged in the horizontal X-axis direction. A first threaded adapter 213 is threadedly mounted on the first drive screw 211. The first drive screw 211 is connected to the first drive motor 22. The first threaded adapter 213 is slidably connected to the first track component 212. The first threaded adapter 213 is connected to the welding strip handling gripper 1.

[0034] The second linear lead screw guide 23 includes a second track component 232 on which a second drive lead screw 231 is rotatably mounted. The second track component 232 is arranged in the horizontal Y-axis direction. A second threaded adapter 233 is threadedly mounted on the second drive lead screw 231. The second drive lead screw 231 is connected to the second drive motor 24. The second threaded adapter 233 is slidably connected to the second track component 232. The second threaded adapter 233 is connected to the first track component 212.

[0035] After gripping the welding strip, the welding strip handling gripper 1, with the help of external power, moves the welding strip above the vision positioning device for photographing and positioning. Then, the vision positioning device compares the parameters of the photograph with the template calibrated by the software to determine the positional difference between the welding strip and the template after the photograph, and then feeds it back to the adjustment component 2. Based on the feedback parameter values, the adjustment component 2 controls the operation of the first drive motor 22 and the second drive motor 24 to drive the first drive screw 211 and the second drive screw 231 to rotate. The rotation of the first drive screw 211 and the second drive screw 231 respectively drives the first threaded adapter seat 213 to slide along the first track member 212 and the second threaded adapter seat 233 to slide along the second track member 232, so that the welding strip can move in the corresponding X-axis and Y-axis directions, so that the welding strip can reach the point calibrated by the template. This achieves effective correction of the welding strip position and effectively avoids the impact of welding strip deviation on the welding effect.

[0036] In the above implementation process, the visual positioning device can adopt a CCD camera. A CCD camera is a digital camera that uses CCD (charge-coupled device) as the photosensitive element. With the CCD chip as the core, it can convert physical images existing in nature into electronic video image signals through photoelectric conversion. It has the characteristics of high sensitivity, low noise, high resolution, good color reproduction, and good signal output consistency.

[0037] Regarding how the power source (first drive motor 22 and second drive motor 24) is controlled based on the data collected by the visual positioning device, please refer to the application of CCD cameras in related fields. This is existing technology and will not be elaborated further here.

[0038] Optionally, both the first drive motor 22 and the second drive motor 24 are servo motors to achieve precise programmed control of the solder strip position correction process.

[0039] In one specific embodiment, there are multiple welding strip transport grippers 1, which are arranged at intervals and are all connected to the adjustment components 2. The multiple adjustment components 2 are connected to a main support beam 4 via a lifting rail assembly 3. The lifting rail assembly 3 is used to control the position adjustment of the welding strip transport grippers 1 in the vertical Z-axis direction. The lifting rail assembly 3 includes a third linear screw guide rail 31 arranged in the vertical Z-axis direction and a third drive motor 32. The third drive motor 32 is mounted on the third linear screw guide rail 31 and is used to provide a power source for the operation of the third linear screw guide rail 31.

[0040] Specifically, the third linear screw guide rail 31 includes a third track component 312 on which a third drive screw 311 is rotatably mounted. The third track component 312 is arranged in the vertical Z-axis direction. The third drive screw 311 is connected to the third drive motor 32. A third threaded adapter 313 is threadedly mounted on the third drive screw 311. The third threaded adapter 313 is slidably disposed with the third track component 312. The third threaded adapter 313 is connected to the second track component 232 of the second linear screw guide rail 23 in the adjustment assembly 2.

[0041] When the third drive motor 32 starts, it will drive the third drive screw 311 to rotate, thereby causing the third threaded adapter 313 to slide along the third track 312, realizing the position adjustment of the welding strip handling gripper 1 in the vertical Z-axis direction.

[0042] Optionally, the third drive motor 32 is a servo motor to achieve precise programmed control during the lifting and lowering process of the welding strip handling gripper 1.

[0043] In the above specific embodiments, the setting of multiple welding strip handling grippers 1 effectively ensures the efficiency of welding strip handling and ensures that multiple welding strips can be in place at the same time. At the same time, each welding strip handling gripper 1 is equipped with an adjustment component 2, which enables positioning and correction of individual welding strips.

[0044] In summary, this utility model has at least the following advantages over the prior art:

[0045] The welding strip positioning mechanism provided by this utility model uses a vision positioning device to capture the position of the welding strip held by the welding strip transporting claws, and uses an adjustment component to adjust the horizontal XY axis direction of the welding strip held by the welding strip transporting claws based on the information collected by the vision positioning device. This can effectively correct the position of the transported welding strip, thereby effectively avoiding the impact of welding strip offset on the welding effect.

[0046] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
