[0001] This application relates to the field of packaging technology, and in particular to a packaging auxiliary device. Background Technology
[0002] In the complex processes of component production, such as string welding and layout, the packaging of laminated frames into warehouses and final packaging require the use of packing straps. When operating manually, the packing straps need to be inserted from under the wooden pallet to the other side. However, because the packing straps are soft, they are easy to bend during insertion and passing through the wooden pallet, making it difficult to reach the other side smoothly. This results in cumbersome and time-consuming operations and low work efficiency.
[0003] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content
[0004] Therefore, it is necessary to provide a packing auxiliary device to address the problem that packing straps are soft and easily bend during insertion and passage through wooden pallets, making it difficult to reach the other side smoothly, resulting in cumbersome and time-consuming operations and low work efficiency.
[0005] A packaging aid device, comprising:
[0006] A support member, the support member comprising a first end and a second end along its own length direction;
[0007] A clamp, which is connected to the support and disposed near the first end;
[0008] A camera assembly, comprising an electrically connected camera and a display screen, wherein the camera is disposed at the first end and the display screen is connected to the support member and disposed near the second end.
[0009] In one embodiment, the clamp includes a telescopic component and a clamping component. The fixed end of the telescopic component is connected to the support member and disposed near the first end. The clamping component is connected to the movable end of the telescopic component. The telescopic component is used to move the clamping component away from the support member.
[0010] In one embodiment, the telescopic component includes a first outer tube and a first inner tube, the first inner tube being movably inserted inside the first outer tube, the first outer tube being fixed to the support member and disposed near the first end, and the clamping component being connected to the first inner tube.
[0011] In one embodiment, the movable end of the telescopic component extends along a first direction and toward a direction away from the support member, the first direction intersecting the length direction of the support member itself.
[0012] In one embodiment, the packaging aid further includes a bracket connected to the support member and disposed near the second end, the bracket being used to support the support member.
[0013] In one embodiment, the support member has a tray protruding from its outer periphery, the bracket is disposed at the bottom of the tray, and the display screen is connected to the tray.
[0014] In one embodiment, the support includes a second outer tube and a second inner tube, the second inner tube being movably inserted inside the second outer tube, the second inner tube having a first end, the second outer tube having a second end, the clamp and the camera being connected to the second inner tube, and the display screen being connected to the second outer tube.
[0015] In one embodiment, the second inner tube includes a first sub-inner tube, a second sub-inner tube, and a third sub-inner tube that are coaxially and nested together. The first sub-inner tube is slidably connected to the interior of the second outer tube, the second sub-inner tube is slidably connected to the interior of the first sub-inner tube, and the third sub-inner tube is slidably connected to the interior of the second sub-inner tube. The third sub-inner tube has the first end, and the clamp and the camera are connected to the third sub-inner tube.
[0016] In one embodiment, the packing aid further includes a control panel connected to the support and located on the side of the display screen near the second end, the control panel being electrically connected to the camera and the display screen.
[0017] In one embodiment, the packaging aid further includes a clamp switch electrically connected to the clamp, the clamp switch being turned on to drive the clamp to open, or being turned off to drive the clamp to close.
[0018] The aforementioned packing auxiliary device secures the packing strap to a support member using clamps, allowing the support member to guide the strapping through the wooden pallet. Due to the guiding and fixing effect of the support member, the packing strap can smoothly move from one side of the pallet to the other, solving the problem of the packing strap easily bending and failing to reach the other side when inserted alone. The camera assembly includes a camera at the first end and a display screen near the second end. During operation, the camera can capture real-time footage of the support member inserting under the wooden pallet and the packing strap passing through the pallet. The operator can clearly see the situation at the first end through the display screen, enabling more accurate control of the insertion direction and position of the support member, as well as the fixing and pulling process of the packing strap. This further improves the accuracy and efficiency of the operation, reduces time wasted due to improper operation, and thus solves the problems of cumbersome and time-consuming operation and low work efficiency.

Detailed Implementation
[0023] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.
[0024] The manufacturing process of photovoltaic modules mainly includes multiple complex steps such as string welding, layout, stacking, lamination, glass bonding, visual inspection, edge sealing, lamination, edge trimming, flipping inspection, frame assembly, and photovoltaic junction box welding. Several processes require the use of packing straps for packaging. For example, in the packing and warehousing of laminated frames and the final packaging, manual operation is required to insert the packing straps from one side of the wooden pallet and extend them from the other side to complete the packing. However, because the packing straps are soft, they often bend and twist during insertion and passage through the wooden pallet, making it difficult to reach the other side smoothly. This results in cumbersome, time-consuming, and inefficient packing operations.
[0025] Based on the above issues, please refer to Figure 1This application provides a packaging assistance device 100, which includes a support member 1, a clamp 2, and a camera assembly 3. In this embodiment, the length direction of the support member 1 is... Figure 1 As shown in direction A, the first direction is Figure 1 The direction shown is B.
[0026] The support member 1 includes a first end 11 and a second end 12 along its length; the clamp 2 is connected to the support member 1 and disposed near the first end 11; the camera assembly 3 includes an electrically connected camera 31 and a display screen 32, with the camera 31 disposed at the first end 11 and the display screen 32 connected to the support member 1 and disposed near the second end 12. When using the packing auxiliary device 100 provided in this application embodiment, the operator holds the second end 12 of the support member 1, causing the clamp 2 to clamp the packing strap, and turns on the camera 31 and the display screen 32. Then, the support member 1 is inserted into the bottom of the wooden pallet 5, and the display screen 32 can display the status of the bottom of the wooden pallet 5 in real time, so that the operator can adjust the position of the packing strap in time, so that the support member 1 carrying the packing strap gradually extends to the other side of the wooden pallet 5.
[0027] Furthermore, the support member 1 has a first end 11 and a second end 12 along its length. Since the strapping material is soft and easily bent and coiled, the support member 1 provides a relatively rigid and stable support structure. During the packing operation, the strapping is fixed to the support member 1. Through the support of the support member 1, the strapping remains relatively straight as it passes through the wooden pallet 5, preventing bending and coiling due to its softness. This allows it to smoothly extend from one side of the wooden pallet 5 to the other, effectively solving the problem of the strapping not being able to reach the other side smoothly. The clamp 2 is connected to the support member 1 and positioned near the first end 11. The clamp 2 can firmly fix the strapping to the support member 1. On the one hand, it ensures the stability of the strapping's position on the support member 1, preventing it from sliding arbitrarily, allowing the strapping to move along the expected path when passing through the wooden pallet 5. On the other hand, when the strapping is extended under the wooden pallet 5, the clamp 2 fixes the strapping, allowing the operator to more easily control the movement of the strapping, improving the accuracy and stability of the operation and reducing the cumbersome operation caused by strapping slippage or inaccurate positioning. The camera assembly 3 includes an electrically connected camera 31 and a display screen 32. The camera 31 is located at the first end 11, and the display screen 32 is connected to the support member 1 and positioned near the second end 12. During the process of the packing strap passing through the wooden pallet 5, the camera 31 can capture the position and status information of the packing strap in real time, and the display screen 32 can display the images captured by the camera 31 in real time. By observing the images on the display screen 32, the operator can clearly understand the specific situation of the packing strap under the wooden pallet 5, such as whether there is any deviation or obstruction. This allows the operator to adjust the position of the support member 1 and the packing strap in a timely manner based on the feedback from the display screen 32, ensuring that the packing strap can pass smoothly through the wooden pallet 5. This avoids multiple attempts and cumbersome operations caused by inaccurate judgment of the packing strap's position, greatly improving the efficiency of the packing operation.
[0028] It should be noted that in this embodiment of the packaging auxiliary device 100, the camera 31 is positioned at the first end 11 of the support member 1, while the clamp 2 is positioned close to the first end 11. In other words, the camera 31 is located at the front end of the clamp 2 along the length of the support member 1. This arrangement allows the camera 31 to provide a more comprehensive and clear view. Positioned at the front end of the clamp 2, the camera 31 can fully capture the portion of the packing strap extending from the clamp 2 and the space within the wooden pallet 5 in front of it when the packing strap enters the wooden pallet 5. The operator can observe in advance through the display screen 32 whether there are any obstacles inside the wooden pallet 5 or whether the packing strap is aligned with the appropriate insertion path, allowing for timely adjustments and improving the success rate of the packing strap passing through the wooden pallet 5 in one pass. Positioning the camera 31 at the front end of the clamp 2 effectively avoids obstruction of the captured image by the clamp 2, ensuring that the operator obtains unobstructed and clear image information, thereby enabling more accurate judgment and operation.
[0029] In an optional embodiment, the support member 1 may be made of metal or plastic, etc.
[0030] In an optional embodiment, the support member 1 may be in the form of a column or a plate, etc.
[0031] In an optional embodiment, to adjust the length of the support member 1, the support member 1 may include a slidingly connected slide rail slider, with the slider sliding relative to the slide rail to extend the length of the support member 1. Alternatively, the support member 1 may include a slidingly connected sleeve, with the sleeve sliding relative to the sleeve to extend the length of the support member 1.
[0032] Please see Figure 2 In some embodiments, the support member 1 includes a second outer tube 13 and a second inner tube 14. The second inner tube 14 is movably inserted inside the second outer tube 13. The second inner tube 14 has a first end 11, and the second outer tube 13 has a second end 12. The clamp 2 and the camera 31 are connected to the second inner tube 14, and the display screen 32 is connected to the second outer tube 13. The size of the wooden pallets 5 used in photovoltaic module production may vary. By setting an extendable support member 1, the length can be flexibly adjusted according to the size of different wooden pallets 5, ensuring that when the packing strap passes through the wooden pallet 5, the support member 1 can smoothly extend from one side under the wooden pallet 5 to the other side, improving the versatility and applicability of the packing auxiliary device 100. The nested structure of the second outer tube 13 and the second inner tube 14 allows the entire support member 1 to maintain good coaxiality and straightness after extension, resulting in more uniform force distribution and reducing the likelihood of shaking or bending deformation.
[0033] Please see Figure 2In some embodiments, the second inner tube 14 includes a first sub-inner tube 141, a second sub-inner tube 142, and a third sub-inner tube 143 arranged coaxially and nested. The first sub-inner tube 141 is internally slidably connected to the second outer tube 13, the second sub-inner tube 142 is internally slidably connected to the first sub-inner tube 141, and the third sub-inner tube 143 is internally slidably connected to the second sub-inner tube 142. The third sub-inner tube 143 has a first end 11, and the clamp 2 and camera 31 are connected to the third sub-inner tube 143. Through the nested sliding of the three layers of the first sub-inner tube 141, the second sub-inner tube 142, and the third sub-inner tube 143, the elongation of the support member 1 can be significantly increased. In photovoltaic module production, facing wooden pallets 5 of different sizes and structures, this design allows the support member 1 to adapt to a wider range of wooden pallet 5 size variations, from smaller wooden pallets 5 to larger or even special-specification wooden pallets 5. The need for packing straps to pass through can be met by adjusting the extension and retraction of the second inner tube 14, further improving the versatility of the packing auxiliary device 100. Each layer of the second inner tube 14 can be independently adjusted to a certain extent, allowing for more precise adjustment of the support member 1's length. This enables accurate control of the support member 1's total length, better adapting to the precise requirements of the packing strap's position and angle in different packing scenarios, thus improving packing accuracy and efficiency. The coaxially nested three layers of second inner tubes 14 ensure that the support member 1 maintains good structural strength and stability even when extended. Each layer works together to share the tensile and compressive forces generated during packing, distributing the stress, reducing the load on individual components, and lowering the risk of deformation or damage due to uneven stress, ensuring the reliability of the device during frequent use. When not in use, each layer can be sequentially retracted and nested within the second outer tube 13, minimizing the overall volume of the support member 1, facilitating storage and saving space in the production workshop. It also helps protect the components, reducing damage caused by collisions or dust erosion.
[0034] Please see Figure 2 In some embodiments, the packaging aid 100 further includes a bracket 4, which is connected to the support member 1 and positioned near the second end 12. The bracket 4 supports the support member 1. The bracket 4 provides additional support points for the support member 1, especially when the support member 1 extends, effectively distributing the force on the support member 1, reducing deformation and swaying, making the entire packaging aid 100 more stable, and ensuring the smooth progress of the packaging process. At the same time, the support member 1 can also share the load borne by the operator holding the support member 1.
[0035] Please see Figure 2 In an optional embodiment, the bracket 4 is connected to the second outer tube 13 of the support member 1.
[0036] In optional embodiments, the bracket 4 can be in the shape of a triangular bracket, a rectangular bracket, an L-shaped bracket, a T-shaped bracket, etc.
[0037] Please see Figure 2 In some embodiments, a tray 5 protrudes from the outer periphery of the support member 1, a bracket 4 is disposed at the bottom of the tray 5, and the display screen 32 is connected to the tray 5. The tray 5 provides a larger planar mounting area for the display screen 32 and the bracket 4, ensuring a more stable installation of the display screen 32 and the bracket 4. Compared to directly mounting the display screen 32 and the bracket 4 on the support member 1, the tray 5 increases the stability and reliability of the installation, reducing the possibility of the display screen 32 shaking or the bracket 4 loosening due to equipment vibration or external impact.
[0038] Please see Figure 2 In an optional embodiment, the tray 5 is disposed around the outer periphery of the support member 1. The tray 5 is a ring disposed around the outer periphery of the support member 1. In other optional embodiments, the tray 5 may be square, rectangular, or other shapes.
[0039] Please see Figure 2 In an optional embodiment, the tray 5 surrounds the second outer tube 13 protruding from the support member 1.
[0040] Please see Figure 2 In some embodiments, the packaging aid 100 further includes a control panel 6, which is connected to the support member 1 and located on the side of the display screen 32 near the second end 12. The control panel 6 is electrically connected to the camera 31 and the display screen 32. The control panel 6 integrates the control functions of the camera 31 and the display screen 32 into one unit. For example, the camera 31 can be turned on or off, the display screen 32 can be turned on or off, and the resolution and brightness of the display screen 32 can be adjusted via the control panel 6, thus eliminating the need to operate the camera 31 and the display screen 32 separately.
[0041] Please see Figure 2 In an optional embodiment, the display screen 32 is mounted on the tray 5, and the control panel 6 is located on the side of the tray 5 near the second end 12 of the support member 1. Positioning the control panel 6 near the second end 12 facilitates operation by the operator when holding the support member 1, allowing them to adjust the camera 31 and the display screen 32.
[0042] Please see Figure 2 In an optional embodiment, the control panel 6 is disposed on the second outer tube 13 of the support member 1.
[0043] The specific structure of fixture 2 will be described below:
[0044] Please see Figure 1In some embodiments, the clamp 2 includes a telescopic component 21 and a clamping component 22. The fixed end of the telescopic component 21 is connected to the support member 1 and is disposed near the first end 11. The clamping component 22 is connected to the movable end of the telescopic component 21. The telescopic component 21 is used to move the clamping component 22 away from the support member 1. The clamp 2 is provided with a telescopic component 21, which can flexibly change the distance between the clamping component 22 and the support member 1, making it easy to operate.
[0045] In an optional embodiment, the clamping component 22 may be a pneumatic clamp or an electric clamp.
[0046] In optional embodiments, the telescopic component 21 may be a sleeve-type telescopic rod, a multi-section telescopic tube, a hinged folding arm, a slide rail telescopic assembly, or a flexible structure such as a corrugated pipe.
[0047] In an optional embodiment, the movable end of the telescopic member 21 can telescopically extend or retract along the length of the support member. See also... Figure 1 Alternatively, in other optional embodiments, in some embodiments, the movable end of the telescopic member 21 extends along a first direction and toward the direction away from the support member 1, and the first direction intersects with the length direction of the support member 1 itself. By extending and retracting the telescopic member 21 along the first direction, the position of the packing strap can be adjusted not only in the length direction of the support member 1, but also in the first direction, thereby expanding the adjustment range of the packing strap position and improving the applicability of the packing auxiliary device 100.
[0048] In some embodiments, the telescopic component 21 includes a first outer tube (not shown) and a first inner tube (not shown). The first inner tube is movably inserted inside the first outer tube, and the first outer tube is fixed to the support member 1 and disposed near the first end 11. The clamping component 22 is connected to the first inner tube. When the first inner tube slides inside the first outer tube, the cooperation between the two provides linear motion guidance, preventing deviation or swaying during telescopic movement. When the first inner tube retracts, it is completely housed inside the first outer tube, saving space.
[0049] In an optional embodiment, both the first outer tube and the first inner tube extend along a first direction.
[0050] In an optional embodiment, the first outer tube is fixed to the third sub-inner tube 143 of the second inner tube 14 of the support member 1.
[0051] Please see Figure 1 In some embodiments, the packaging aid 100 further includes a clamp switch 7 electrically connected to the clamp 2. The clamp switch 7 is used to be turned on to drive the clamp 2 to open, or to be turned off to drive the clamp 2 to close. The clamp switch 7 facilitates control over the opening and closing of the clamp 2.
[0052] Please see Figure 1In an optional embodiment, the clamp switch 7 is electrically connected to the clamping component 22 of the clamp 2.
[0053] Please see Figure 1 In an optional embodiment, the clamp switch 7 may be disposed on the telescopic component 21 of the clamp 2.
