Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module manufacturing technology, and more specifically, to a material box. Background Technology

[0002] In the manufacturing of photovoltaic modules, dicing and stringing of solar cells are critical process steps. For production lines without integrated dicing and stringing machines, the half-cell loading box plays a vital role. It is used to safely transfer the solar cells to the stringing machine after the dicing machine has cut the half-cells, enabling continuous production. In existing technology, the half-cell loading box typically consists of three main parts: a box base for supporting and positioning the solar cells; 14 limiting posts to ensure the stability of the solar cells during transportation and prevent displacement or damage caused by vibration; and double-bent handles symmetrically arranged on both sides of the box base for easy handling and carrying by operators.

[0003] However, existing double-bend handle designs mostly use an inverted U-shaped structure, which, while meeting basic handling needs, suffers from a significant lack of operating space. Specifically, when operators wear dust gloves and use both hands, the distance between their hands and the edge of the battery cells is too close, making it easy for them to touch the edge of the battery cells during lifting, leading to an increased rate of damage to the battery cells. Utility Model Content

[0004] The main purpose of this utility model is to provide a material box that can solve the problem that in the prior art, the distance between the hand and the edge of the battery cell is too close during the handling process, which makes it easy to touch the edge of the battery cell during the lifting process, resulting in an increased rate of battery cell damage.

[0005] To achieve the above objectives, this utility model provides a material box, comprising: a base plate having a first end and a second end disposed opposite to each other along a first direction; and a handle having at least one handle at each of the first and second ends of the base plate, the handle comprising a connecting portion, an inclined portion, and a gripping portion, the first end of the connecting portion being connected to the base plate, the first end of the inclined portion being connected to the second end of the connecting portion, the second end of the inclined portion extending inclinedly away from the center of the base plate, and the gripping portion comprising a gripping section and an extension section, the first end of the extension section being connected to the inclined portion, the second end of the extension section being connected to the gripping section, and the extension section forming a first angle α with the vertical plane, the value of α being 0°≤α≤10°.

[0006] Furthermore, the extension segment extends vertically; and / or the length L of the extension segment is in the range of 30mm≤L≤40mm.

[0007] Furthermore, the connecting part extends vertically and is parallel to the extension section, and the length of the connecting part is less than the length of the extension section.

[0008] Furthermore, the material box also includes multiple first limiting structures. Along the second direction, the base plate has a third end and a fourth end. The first end, the second end, the third end, and the fourth end of the base plate are each provided with at least one first limiting structure, and the multiple first limiting structures together form an accommodating space.

[0009] Furthermore, a first guide slope is provided on the side of the first limiting structure facing the receiving space.

[0010] Furthermore, the first limiting structure has a first stop surface on the side facing the receiving space, and a buffer structure is provided on the first stop surface.

[0011] Furthermore, the material box also includes multiple second limiting structures. At least one second limiting structure is provided at the third end and the fourth end of the bottom plate. The second limiting structure at the third end of the bottom plate and the second limiting structure at the fourth end of the bottom plate are provided in a one-to-one correspondence to divide the accommodating space into at least two accommodating sub-spaces arranged sequentially along the first direction.

[0012] Furthermore, along the first direction, the top of the second limiting structure has a second guide slope and a third guide slope, with the second guide slope and the third guide slope set at a second included angle β, the value of which is 30°≤β≤60°.

[0013] Furthermore, along the first direction, the second limiting structure has a second stop surface and a third stop surface that are arranged opposite to each other, and a buffer structure is provided on both the second stop surface and the third stop surface.

[0014] Furthermore, both the first limiting structure and the second limiting structure are movably disposed relative to the base plate along the first direction.

[0015] The present invention utilizes a base plate and a handle. The handle comprises a connecting part, an inclined part, and a gripping part (including a gripping section and an extension section). The connecting part is connected to the base plate to maintain a stable connection between the handle and the material box. The second end of the inclined part extends inclinedly away from the center of the base plate, which not only increases the overall height of the handle but also increases the lateral distance between the hand and the battery cell. The extension section of the gripping part further increases the overall height of the handle, significantly expanding the operating space. The hand will not touch the edge of the battery cell when gripping the gripping section. At the same time, the extension section of the gripping part forms a first angle with the vertical plane, further optimizing the operator's hand posture and allowing the hand to avoid the edge of the battery cell during gripping, thus avoiding direct contact and greatly reducing the battery cell damage rate.

[0024] It should be noted that, where there is no conflict, the embodiments and features in the embodiments of this utility model can be combined with each other. The present utility model will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] See also Figures 1 to 5As shown, this utility model provides a material box, which includes: a base plate 10, which has a first end and a second end disposed opposite to each other along a first direction; and a handle 20, which is provided at least one handle 20 at both the first end and the second end of the base plate 10. The handle 20 includes a connecting part 21, an inclined part 22, and a gripping part 23. The first end of the connecting part 21 is connected to the base plate 10, the first end of the inclined part 22 is connected to the second end of the connecting part 21, and the second end of the inclined part 22 extends inclinedly away from the center of the base plate 10. The gripping part 23 includes a gripping section 231 and an extension section 232. The first end of the extension section 232 is connected to the inclined part 22, and the second end of the extension section 232 is connected to the gripping section 231. The extension section 232 forms a first angle α with the vertical plane, and the value of α is in the range of 0°≤α≤10°.

[0026] In this embodiment, the handle 20 consists of a connecting part 21, an inclined part 22, and a gripping part 23 (including a gripping section 231 and an extension section 232). This multi-segment structure increases the space for hand operation compared to the traditional "inverted U-shaped" handle. The connecting part 21 is connected to the base plate 10 to maintain a stable connection between the handle 20 and the material box. The second end of the inclined part 22 extends inclined away from the center of the base plate 10, which not only increases the overall height of the handle 20 but also increases the lateral distance between the hand and the battery cell. The extension section 232 of the gripping part 23 further increases the overall height of the handle 20, significantly expanding the operating space (up to 70%). The hand will not touch the edge of the battery cell when gripping the gripping section 231. At the same time, the extension section 232 of the gripping part 23 forms a first angle α (0°≤α≤10°) with the vertical plane, further optimizing the operator's hand posture and allowing the hand to avoid the edge of the battery cell during gripping, avoiding direct contact and greatly reducing the battery cell damage rate. The handle in this application not only improves the comfort of employees' handling operations, but also reduces the risk of hand contact with battery cells through optimized structure, thereby effectively reducing the damage rate and improving operational safety.

[0027] It should be noted that the cell breakage rate refers to the breakage rate of cells during normal production after unpacking. The calculation formula is: Breakage rate = Number of broken cells / Number of cells put into production * 100%. Using existing material boxes for cell storage, the cell breakage rate is 0.21%, while using the material box of this application, the cell breakage rate is 0.15%, a reduction of 0.06%.

[0028] The primary function of the handle in this application is spatial avoidance and adaptation. For the battery cell material box system (including the material tray base, limit blocks and other surrounding structures), structural improvements enable the operating end (the equivalent functional segment of the hand) to reach the target grasping / operating position without interference within the working space. At the same time, based on ergonomic principles, it adapts to the mechanical requirements of grasping force during manual operation, achieving synergistic optimization of spatial layout compatibility and human-computer interaction efficiency.

[0029] Preferably, the first included angle α is in the range of 0°≤α≤5°.

[0030] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the extension segment 232 extends in the vertical direction.

[0031] In this embodiment, the extension 232 extends vertically, which significantly increases the overall height of the handle 20, placing the hand at a higher position when gripping. This helps to further increase the vertical distance between the hand and the edge of the battery cell, thereby reducing the probability of the hand accidentally touching the edge of the battery cell during handling and reducing the loss rate. Furthermore, designing the extension 232 to extend vertically effectively utilizes the vertical space above the material box, providing more vertical clearance for the operator's hands. This not only reduces the chance of contact between the hand and the battery cell but also makes the operator's movements more fluid when gripping the handle 20, without requiring significant adjustments to hand position, thus improving the smoothness and safety of handling.

[0032] In one embodiment of this utility model, the length L of the extension segment 232 is in the range of 30mm≤L≤40mm.

[0033] In this embodiment, the extension 232 is between 30mm and 40mm in length. Compared to traditional designs, this significantly increases the distance between the operator's hand and the edge of the battery cell. This allows the operator's fingers to bend naturally when gripping the handle 20, avoiding direct contact with the edge of the battery cell and reducing the risk of damage during handling. Simultaneously, it optimizes the hand's gripping posture, reduces the bending angle of the hand during handling, making operation more comfortable, reducing hand fatigue, and improving work efficiency.

[0034] In one embodiment of this utility model, the length of the extension section 232 is 35mm, the length of the connecting part 21 is 15mm, and the overall height of the handle is 60mm.

[0035] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the connecting part 21 extends in the vertical direction and is parallel to the extension section 232, and the length of the connecting part 21 is less than the length of the extension section 232.

[0036] In this embodiment, the length of the connecting part 21 is less than that of the extension section 232. The longer extension section 232 can distribute the load and avoid excessive stress on the connecting part 21, thereby enhancing the structural stability of the entire handle 20.

[0037] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the material box further includes a plurality of first limiting structures 40. Along the second direction, the bottom plate 10 has a third end and a fourth end. The first end, the second end, the third end and the fourth end of the bottom plate 10 are each provided with at least one first limiting structure 40, and the plurality of first limiting structures 40 together form an accommodating space.

[0038] In this embodiment, the first limiting structure 40 ensures the precise position of the battery cells in the material box, effectively preventing the battery cells from shifting or sliding during handling or transportation. The housing space enclosed by the first limiting structure 40 allows for more orderly stacking of the battery cells, and the handle 20 located on the outer periphery of the housing space makes loading and unloading the material box more convenient.

[0039] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the first limiting structure 40 is provided with a first guide slope 41 on the side facing the accommodating space.

[0040] In this embodiment, the first guide ramp 41 guides the solar cells smoothly into the receiving space, helping the operator to quickly and correctly align and place the solar cells into the receiving space. Especially on high-speed production lines, this design can reduce assembly time and avoid delays caused by frequent adjustments to the position of the solar cells, thereby improving overall production efficiency.

[0041] In one embodiment of the present invention, the first limiting structure 40 has a first stop surface 42 on the side facing the accommodating space, and a buffer structure is provided on the first stop surface 42.

[0042] In this embodiment, after the battery cell is installed in the receiving space, multiple first stop surfaces 42 cooperate to provide circumferential stopping and limiting of the battery cell. A buffer structure is provided on the first stop surface 42, which can absorb the impact force of the battery cell during placement, preventing the battery cell from directly impacting the hard first stop surface 42. This greatly reduces the risk of damage to the battery cell caused by hard contact and improves the yield rate of the finished product. The edges of the battery cell are often relatively fragile and easily damaged during contact and handling. By providing a buffer structure on the first stop surface 42, a soft contact can be formed when the edge of the battery cell contacts the first stop surface 42, reducing edge wear of the battery cell.

[0043] See also Figures 1 to 5As shown, in one embodiment of the present invention, the material box further includes a plurality of second limiting structures 30. At least one second limiting structure 30 is provided at the third end and the fourth end of the bottom plate 10. The second limiting structure 30 located at the third end of the bottom plate 10 and the second limiting structure 30 located at the fourth end of the bottom plate 10 are provided in a one-to-one correspondence to divide the accommodating space into at least two accommodating sub-spaces arranged sequentially along the first direction.

[0044] In this embodiment, the second limiting structure 30 can divide the accommodating space into multiple independent accommodating subspaces. Each accommodating subspace can be used to load a certain number of battery cells, improving loading efficiency. At the same time, the divided accommodating subspaces can be used to classify and store battery cells from different batches or production lines, facilitating batch tracking and quality control. Once a quality problem is detected, the specific accommodating subspace can be quickly located, reducing the cost of recall and rework.

[0045] See also Figures 1 to 5 As shown, in one embodiment of the present invention, along the first direction, the top of the second limiting structure 30 has a second guide slope 31 and a third guide slope 32, the second guide slope 31 and the third guide slope 32 are set at a second included angle β, and the value range of the second included angle β is 30°≤β≤60°.

[0046] In this embodiment, the second guide ramp 31 and the third guide ramp 32 are provided to guide the battery cells during the process of inserting them into the receiving space.

[0047] See also Figures 1 to 5 As shown, in one embodiment of the present invention, along the first direction, the second limiting structure 30 has a second stop surface 33 and a third stop surface 34 disposed opposite to each other, and a buffer structure is provided on both the second stop surface 33 and the third stop surface 34.

[0048] In this embodiment, the second stop surface 33 and the third stop surface 34 of the second limiting structure 30 can respectively stop and limit the battery cell inserted into the corresponding receiving sub-space. Both the second stop surface 33 and the third stop surface 34 are provided with a buffer structure, which can form a soft contact when the edge of the battery cell comes into contact with the second stop surface 33 and the third stop surface 34, reducing edge wear of the battery cell and avoiding direct contact between the edge of the battery cell and the hard stop surface, thereby reducing the risk of damage to the battery cell.

[0049] In one embodiment, the cushioning structure is a sponge or a rubber pad.

[0050] In one embodiment, buffer structures are provided on the first stop surface 42, the second stop surface 33, and the third stop surface 34, and the outer periphery of the buffer structure is covered with a plastic film. The plastic film is made of nylon material and has a relatively smooth surface, which can reduce the friction between the edge of the battery cell and the buffer structure, and ensure that the battery cell can be smoothly installed into the receiving space.

[0051] In one embodiment of the present invention, the first limiting structure 40 and the second limiting structure 30 are both movably disposed relative to the base plate 10 along a first direction.

[0052] In this embodiment, by allowing the first limiting structure 40 and the second limiting structure 30 to move along the first direction, it is possible to adapt to battery cells of different sizes, thereby improving the applicability of the material box.

[0053] In one embodiment of the present invention, the connecting part 21 is slidably connected to the base plate 10 and can slide relative to the base plate 10 in a first direction.

[0054] In this embodiment, the position of the handle 20 relative to the base plate 10 is adjustable, which can accommodate battery cells of different lengths. This eliminates the need to customize material boxes of different sizes, reduces equipment investment costs, and improves the flexibility and efficiency of the production line.

[0055] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the base plate 10 is provided with a through hole 11, which can reduce the weight of the base plate 10 and save costs.

[0056] See also Figures 1 to 5 As shown, in one embodiment of the present invention, the base plate 10 is provided with a plurality of first sliding grooves 12 extending along a first direction, a plurality of second sliding grooves 13 extending along a first direction, and a plurality of third sliding grooves 14 extending along a first direction. A first limiting structure 40 is slidably disposed in each first sliding groove 12 and each second sliding groove 13. The plurality of third sliding grooves 14 are correspondingly disposed with the plurality of second limiting structures 30, and the second limiting structures 30 are slidably disposed in the corresponding third sliding groove 14.

[0057] For the first limiting structure 40 slidably disposed within the first slide groove 12, along the second direction, the top of the first slide groove 12 has a first limiting edge and a second limiting edge extending from one end of the first slide groove 12 to the other end along the first direction on opposite sides. The distance between the first limiting edge and the second limiting edge is less than the width of the first slide groove 12. The bottom of the first limiting structure 40 includes a protrusion 43 and two stop limiting surfaces 44. Along the second direction, the two stop limiting surfaces 44 are respectively located on opposite sides of the protrusion 43. The protrusion 43 passes through the gap between the first limiting edge and the second limiting edge into the first slide groove 12. One of the two stop limiting surfaces 44 is connected to the first limiting edge. The top surface of one limiting edge is abutted, and the other of the two stop limiting surfaces 44 is abutted with the top surface of the second limiting edge. A first pressure plate is provided at the bottom of the protrusion 43. The first pressure plate is located in the first slide groove 12 and below the first and second limiting edges. The first pressure plate is connected to the protrusion 43 by bolts. When the first limiting structure 40 slides to a preset position and needs to be locked, the bolts are tightened. At this time, one end of the first pressure plate cooperates with one of the stop limiting surfaces 44 to clamp the first limiting edge, and the other end of the first pressure plate cooperates with the other stop limiting surface 44 to clamp the second limiting edge, thereby achieving the positioning of the first limiting structure 40 in the first slide groove 12. When it is necessary to adjust the position of the first limiting structure 40, the bolts are loosened. At this time, the first limiting structure can slide in the first slide groove 12 along the first direction. Similarly, the positioning of the first limiting structure 40 that slides in the second slide groove 13 is also achieved through the above principle, which will not be elaborated here.

[0058] For the second limiting structure 30 slidably disposed within the third slide groove 14, along the second direction, a third limiting edge and a fourth limiting edge are provided on opposite sides of the top of the third slide groove 14, extending from one end of the third slide groove 14 to the other end along the first direction. The distance between the third limiting edge and the fourth limiting edge is less than the width of the third slide groove 14. The bottom of the second limiting structure 30 includes a protrusion 35, which penetrates into the third slide groove 14 through the gap between the third limiting edge and the fourth limiting edge. A second pressure plate is provided at the bottom of the protrusion 35. The second pressure plate is positioned within the third slide groove and below the third and fourth limiting edges. The second pressure plate is bolted to the protrusion 35. When the second limiting structure 30 slides to a preset position and needs to be locked, the bolts are tightened. At this time, one end of the top surface of the second pressure plate abuts against the third limiting edge, and the other end abuts against the fourth limiting edge, thus pressing the second pressure plate firmly against the third and fourth limiting edges. This prevents the second limiting structure 30 from sliding along the first direction, thereby achieving positioning of the second limiting structure 30 within the third slide groove 14. When the position of the second limiting structure 30 needs to be adjusted, the bolts are loosened. At this time, the second limiting structure 30 can slide along the first direction within the third slide groove 14.

[0059] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: A base plate and a handle are provided. The handle consists of a connecting part, an inclined part, and a gripping part (including a gripping section and an extension section). The connecting part is connected to the base plate, maintaining a stable connection between the handle and the material box. The second end of the inclined part extends inclinedly away from the center of the base plate, which not only increases the overall height of the handle but also increases the lateral distance between the hand and the battery cell. The extension section of the gripping part further increases the overall height of the handle, significantly expanding the operating space. The hand will not touch the edge of the battery cell when gripping the gripping section. At the same time, the extension section of the gripping part forms a first angle with the vertical plane, further optimizing the operator's hand posture, allowing the hand to avoid the edge of the battery cell during gripping, preventing direct contact and greatly reducing the battery cell damage rate.
