DETAILED DESCRIPTION

[0024] In order to more clearly illustrate the technical solutions of the embodiments of the present invention, the following briefly introduces the drawings required for use in the embodiments. Obviously, the drawings described below are some embodiments of the present invention. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work.

[0025] See also Figure 1-6 The embodiment of the present invention provides an integrated device for the final inspection and packaging of the back and front of solar modules, including a back inspection platform, a front inspection platform, and a weighing and counting unit. The front inspection platform is arranged at the output end of the back inspection platform. The back inspection platform includes a support frame 11 and a conveying mechanism 12. The support frame 11 is a rigid frame standing on the ground. The conveying mechanism 12 is transmission-arranged on the support frame 11, and the upper part thereof is used to place the solar modules to be inspected. The front inspection platform includes a first ladder frame 21, a second ladder frame 22, and a tray 23 arranged between the first ladder frame 21 and the second ladder frame 22. The first ladder frame 21 has an inclined left side wall, and the second ladder frame 22 has an inclined right side wall for the solar module 100 to lean against. The weighing and counting unit is used to detect the total weight of the modules on the tray 23 in real time and send a prompt message to the personnel.

[0026] In this solution, each component is transferred to the back inspection platform, and the personnel inspect the back side. Then the component is lifted and placed on the tray 23 between the two ladder frames, close to the right inclined side wall of the second ladder frame 22. When lifting and placing, the component can be rotated 90 degrees, keeping the front of the component facing the back inspection platform, that is, facing the inspector. At this time, the personnel can directly inspect the front side.

[0027] During this process, the back side 101 is inspected on the back inspection platform, and the front side 102 is inspected on the second ladder frame 22. In addition, this process only requires lifting and lowering the components once. After 30 components are placed, packaging begins. At this time, it is only necessary to move the upper edge of each component to the right at a small angle to keep it upright, and then tighten the transverse packing tape 32 and the longitudinal packing tape 31 for packaging. After packaging, the tray 23 on which the components are placed can be removed.

[0028] During the above inspection and packaging process, the components were moved only once, and the rotation angle of the components was 90 degrees. The inspection process and packaging process were integrated and only two people were needed to complete them.

[0029] In the prior art, after the back inspection is completed, the component is flipped 180 degrees so that the front side 102 is facing upward and placed on a pallet 23. This is the first time the component is moved. After the personnel have checked the front side 102 and stacked 30 pieces, another pallet 23 is prepared. Each component is flipped 90 degrees in turn, kept upright, and moved to another pallet 23. After all 30 pieces are upright, the packing tape is inserted to complete the packaging. In this process, two pallets 23 are required and the component needs to be moved twice. The first flip is 180 degrees and the second flip is 90 degrees. Both are large-scale flips, which greatly increase the probability of mechanical damage to the component, increase the difficulty of operation, and reduce labor efficiency. Moreover, the packaging process is separate from the inspection process, and requires two separate packaging personnel and two inspection personnel, which also increases labor costs. See Figure 7-9 , Fig.10 , 11 、12.

[0030] Furthermore, a flexible layer is wrapped on the inclined side walls of the first ladder frame 21 and the second ladder frame 22 to avoid mechanical collision damage to the components.

[0031] Furthermore, the first ladder frame 21 and the second ladder frame 22 are fixedly arranged on the ground, and the tray 23 is movably arranged between the first ladder frame 21 and the second ladder frame 22, so as to be pulled out vertically from the space between the first ladder frame 21 and the second ladder frame 22. In one embodiment, a ground wheel is arranged under the tray 23, and the first ladder frame 21 and the second ladder frame 22 are fixed on the ground by screws.

[0032] Furthermore, the integrated equipment also includes a packaging component, which includes a longitudinal packaging belt 31 and a transverse packaging belt 32. The longitudinal packaging belt 31 is at least two, and the two ends of the longitudinal packaging belt 31 are overlapped on the first ladder frame 21 and the second ladder frame 22, and are clamped on both sides of the first ladder frame 21 and the second ladder frame 22. The middle part is laid flat on the inclined side walls of the first ladder frame 21 and the second ladder frame 22 and the plane of the tray 23, so that the inspected components are placed above the longitudinal packaging belt 31. The transverse packaging belt 32 is provided with a reel 33 for storing a certain length of the transverse packaging belt 32 in advance, and the reel 33 is rotatably set on the second ladder frame 22.

[0033] Furthermore, the packaging assembly also includes a straightening frame 34, which includes a horizontal bottom plate 341 and a vertical upright plate 342. The horizontal floor is used to be inserted under the pallet 23, and the vertical upright plate 342 is vertically connected to the horizontal bottom plate 341. The height of the vertical upright plate 342 is greater than 1 / 2 of the assembly height.

[0034] In this scheme, before the inspected components are placed on the pallet 23, the transverse packing tape 32 and the longitudinal packing tape 31 are set in advance, and according to the packaging requirements, every 30 blocks are packaged. When the number of inspected component boards reaches 30 blocks, the transmission of the conveying mechanism 12 is suspended, and the straightening frame 34 is pushed in the direction close to the components so that the rightmost component is close to the straightening frame 34 and maintained in a vertical position. Then, each adjacent component is close to the component on the right and maintained in a vertical position, and then the transverse packing tape 32 is pulled out to surround the components and tighten the packaging. Then, the two longitudinal packing tapes 31 are pulled out to surround the components and tighten the packaging, thereby completing the packaging. At this time, the straightening frame 34 is withdrawn into the first trapezoidal frame 21, and the pallet 23 is pulled out along the space between the two trapezoidal frames to complete the inspection and packaging of a batch.

[0035] During this process, the packaging tape is pre-placed under the component to avoid the need to move the component a second time in order to insert the packaging tape during packaging, thereby reducing the number of times the component is handled and transferred and reducing the probability of mechanical damage.

[0036] In this step, in order to keep the components in the vertical center during packaging, a straightening frame 34 is provided to assist the components to stand upright. The straightening frame 34 is movably provided under the ladder frame. When needed during packaging, it is pushed toward the components and withdrawn after completion to avoid obstructing the pulling out of the tray 23. If the straightening frame 34 is not provided, the thickness of a single component is relatively thin, and it is necessary to observe it manually with the naked eye to keep it in the vertical upright state, resulting in large errors, and even making it impossible for individual or multiple components to maintain the vertical state. There are gaps between them after packaging, resulting in loose packaging and damage between components due to friction.

[0037] Furthermore, the conveying mechanism 12 includes a transmission motor 121 , a transmission shaft 122 , and a synchronous belt 123 . The transmission motor 121 is connected to the transmission shaft 122 , and the transmission shaft 122 is connected to the synchronous belt 123 .

[0038] Furthermore, the weighing and counting unit includes a weighing sensor 41 and a prompting device. The weighing sensor 41 is connected to the prompting device. The prompting device receives the signal of the weighing sensor 41 and displays it to prompt the personnel that the number of components on the tray 23 has reached a preset number. The tray 23 includes an upper plate 231, a lower plate 232 and a weighing sensor 41 disposed therebetween. A ground wheel is disposed below the lower plate 232 to vertically move the tray 23. The upper plate 231 is used to place components. The upper end of the weighing sensor 41 is fixed to support the upper plate 231, and the lower end is fixed to the lower plate 232. In implementation, a reference weight m0 is preset inside the weighing sensor 41, which is the total weight of 30 component boards. The weighing sensor 41 detects the total weight of the components on the tray 23 in real time, and compares the detected real-time data with m0. When the comparison result is less than the preset deviation range, a signal is sent to the prompting device, and the prompting device reminds the personnel that the number has reached 30 by sounding or emitting light. In this solution, the number of components can be measured, avoiding manual counting and recording by personnel, and the measurement is accurate, convenient and fast.

[0039] Furthermore, the prompting device is a display light or an alarm.

[0040] The modules or units in the device of the embodiment of the present invention may be combined, divided or deleted according to actual needs.
