Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module technology, and in particular to a material conveying box and a photovoltaic module production system. Background Technology

[0002] In the current photovoltaic (PV) industry production process, PV companies often engage in both PV cell and module production simultaneously to control costs and stabilize supply and demand, with cell and module workshops frequently located in the same factory area. After production, PV cells are typically stacked in groups of 100 and packaged into specially designed corrugated cardboard boxes. To protect and secure the cells, cushioning material is added around the boxes before they are sealed in plastic. After sealing, the boxes are packed and stacked before being transported to the raw material warehouse in the PV module workshop. In the module workshop, the cells undergo further unpacking before they can be used to produce PV modules.

[0003] In this process, most of the packaging materials used are single-use items, difficult to reuse. This not only brings high packaging costs to enterprises but also causes serious waste of resources. According to relevant statistics, the cost of materials such as cardboard boxes, labels, and wrapping materials alone accounts for a considerable proportion of the enterprise's production costs. At the same time, traditional packaging methods are cumbersome, involving multiple steps from packaging and transportation of battery cells to unpacking. This not only consumes a lot of manpower and resources but also easily leads to wear and tear, microcracks, and other problems with battery cells during transportation due to the limited protective effect of packaging materials, affecting product quality.

[0004] Furthermore, some reusable battery box designs in related technologies simply place the solar cells directly inside the box. Because there is a gap between the solar cells and the box, and the transport distance from the battery workshop to the module workshop is typically about 400 meters, the solar cells, being thin and fragile products, will constantly impact the inner wall of the box during transportation if they encounter shaking or bumps. Frequent impacts are highly likely to cause damage and microcracks in the solar cells, greatly increasing the risk of loss during transportation and seriously affecting product quality and yield.

[0005] Based on this, a novel material conveying box and photovoltaic module production system have been developed in this utility model to solve the above problems. Utility Model Content

[0006] The first objective of this invention is to provide a conveying box in which the clamping and holding mechanism continuously provides resistance, ensuring that the material will not loosen even during long-distance transportation or in bumpy environments, thus guaranteeing the stability of the material during transportation.

[0007] This utility model adopts the following technical solution: a material conveying box, comprising:

[0008] Material box base;

[0009] The material box cover is detachably mounted on the material box base, forming a cavity for containing materials;

[0010] The linkage component is set on the material box cover. The input end of the linkage component is equipped with a drive component, and the output end of the linkage component is equipped with a clamping component. The drive component drives the clamping component to move linearly through the linkage component to clamp or release the material.

[0011] The clamping and retaining mechanism is located on the material box cover and is used to maintain the clamped and fixed state of the clamped parts.

[0012] Furthermore, the clamping and holding mechanism includes a first damping structure, which is installed at the connection between the material box cover and the drive assembly and acts on the drive assembly to maintain the clamping and fixed state of the clamping member.

[0013] Furthermore, the clamping and holding mechanism includes a second damping structure, which is disposed on the material box cover and acts on the linkage component to maintain the clamping and fixed state of the clamping component.

[0014] Furthermore, the linkage component includes an L-shaped rack arm, which is slidably mounted on the material box cover. The L-shaped rack arm has a horizontal part and a vertical part, and the vertical part of the L-shaped rack arm is fixedly connected to the clamping member.

[0015] Furthermore, four L-shaped rack arms are provided, and the four L-shaped rack arms are divided into two groups, with two rack arms in each group symmetrically arranged on both sides of the drive assembly.

[0016] One set of L-shaped rack arms is arranged along the length of the material box cover, and the other set of L-shaped rack arms is arranged along the width of the material box cover; the two sets of L-shaped rack arms are staggered in the height direction of the material box cover.

[0017] Furthermore, the drive component includes gears;

[0018] A rack that meshes with a gear is provided on the horizontal part of the L-shaped rack arm. The rotating gear drives the L-shaped rack arm and the clamping member to move linearly.

[0019] Furthermore, each side wall of the material box cover is provided with a moving channel, the clamping component is set in the moving channel, and a limiting baffle is set on the side of the moving channel near the inside of the cavity. The limiting baffle is used to limit the moving range of the linkage component.

[0020] Furthermore, the material box base is provided with an air inlet and a gas channel connected to the air inlet. The outlet of the gas channel is set towards the material inside the cavity, and adjacent materials are separated by airflow to form a gap.

[0021] Furthermore, one of the material box base and the material box cover is provided with a magnetic head, and the other is provided with a magnetic base that cooperates with the magnetic head. The magnetic head and magnetic base are used to lock the material box when it is closed. Compared with related technologies, the beneficial effects of this utility model are:

[0022] The general working principle of the conveying box in this utility model is as follows:

[0023] The drive component acts as the power source, transmitting power to the clamping component via the linkage component. This allows the clamping component to move linearly, moving towards the material and applying clamping force to secure it. During this process, the clamping and holding mechanism on the material box cover continuously locks the clamping component, effectively resisting external vibrations or other external forces, preventing it from loosening, ensuring stable clamping force, and keeping the material firmly clamped at all times.

[0024] Meanwhile, due to the continuous resistance provided by the clamping and holding mechanism, the material will not loosen even during long-distance transportation or bumpy environments (such as 400-meter inter-factory transfer), which greatly ensures the stability of the material during transportation.

[0025] Furthermore, the conveyor box in this invention is reusable, which not only reduces packaging costs but also avoids waste of packaging materials, demonstrating good economic and environmental benefits.

[0026] The second objective of this invention is to provide a photovoltaic module production system, which includes the aforementioned conveyor box. Attached Figure Description

Detailed Implementation

[0040] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0041] The following is in conjunction with the appendix Figure 1 To be continued Figure 11 The present invention will be described in detail with specific embodiments:

[0042] like Figures 1 to 11As shown, this utility model provides a material conveying box, which includes a box base 1, a box cover 2, a linkage assembly 3, a drive assembly 4, and a clamping and holding mechanism 5. The box cover 2 is detachably mounted on the box base 1, forming a cavity for containing materials. In this embodiment, the material is mainly battery cells 8. A damping clamping mechanism is provided on the box cover 2.

[0043] The linkage component 3 is installed on the material box cover 2, and the input end of the linkage component 3 is provided with a drive component 4, and the output end of the linkage component 3 is provided with a clamping component 6. The drive component 4 drives the clamping component 6 to move linearly through the linkage component 3 to clamp or release the material.

[0044] The clamping and holding mechanism 5 is disposed on the material box cover 2, and is used to maintain the clamped and fixed state of the clamping member 6. The general working principle of this conveying material box in this utility model is as follows:

[0045] The drive component 4 serves as the power source, transmitting power to the clamping component 6 via the linkage component 3. This allows the clamping component 6 to move linearly, moving towards the material and applying clamping force to secure it. During this process, the clamping and holding mechanism 5 on the material box cover 2 continuously locks the clamping component 6, effectively resisting external vibrations or other external forces, preventing the clamping component 6 from loosening, ensuring stable clamping force, and keeping the material firmly clamped at all times.

[0046] Meanwhile, due to the continuous resistance provided by the clamping and holding mechanism 5, the material will not loosen even during long-distance transportation or bumpy environments (such as 400-meter inter-factory transmission), which greatly ensures the stability of the material during transportation.

[0047] Furthermore, the conveyor box in this invention is reusable, which not only reduces packaging costs but also avoids waste of packaging materials, demonstrating good economic and environmental benefits.

[0048] Furthermore, the clamping and holding mechanism 5 in this invention can be implemented in various ways. For example, a plug-in seat can be provided on the top of the material box cover 2, and correspondingly, a plug-in hole matching the plug-in seat can be provided on the drive component 4. After the clamping member 6 clamps the material, the fixing pin is inserted into the plug-in seat and the plug-in hole in sequence, thereby preventing the drive component 4 from rotating and realizing manual limiting. Of course, the fixing pin can also be inserted into the linkage component 3 to realize the fixed limiting of the linkage component 3, thereby maintaining the clamping and fixed state of the clamping member 6.

[0049] The clamping and holding mechanism 5 can act on the drive assembly 4. Specifically, the clamping and holding mechanism 5 includes a first damping structure. The first damping structure is disposed at the connection between the material box cover 2 and the drive assembly 4. The first damping structure provides damping force and acts on the drive assembly 4 to maintain the clamping and fixed state of the clamping member 6.

[0050] During operation, the drive assembly 4 acts as a power source, transmitting power to the clamping member 6 via the linkage assembly 3. This allows the clamping member 6 to move linearly, moving towards the material and applying clamping force to secure it. During this process, the first damping structure on the material box cover 2 activates, generating resistance through friction or elastic deformation to prevent the drive assembly 4 from moving. This prevents the clamping member 6 from loosening due to external vibrations or other forces, thus maintaining stable clamping force and ensuring the material is firmly clamped.

[0051] When material needs to be released, the drive component 4 reverses its movement, and the linkage component 3 drives the clamping component 6 to retract in a linear direction. At this time, the first damping structure still functions, providing a buffering effect during the release process to prevent the clamping component 6 from rebounding rapidly and to prevent the material from being displaced or damaged due to rapid retraction.

[0052] Similarly, the clamping and holding mechanism 5 can also act on the linkage component 3. Specifically, the clamping and holding mechanism 5 includes a second damping structure, which is disposed on the material box cover 2 and acts on the linkage component 3 to maintain the clamping and fixing state of the clamping member 6, so as to prevent the clamping member 6 from loosening due to external vibration or other external forces, thereby maintaining the stability of the clamping force and ensuring that the material is firmly clamped.

[0053] Furthermore, in some specific embodiments, there are various ways to implement the cooperation between the linkage component 3, the drive component 4, and the clamping and holding mechanism 5.

[0054] As in Option 1, Figure 10 As shown, the drive assembly 4 uses a first bevel gear 40, and the linkage assembly 3 consists of four sets of screw and nut structures arranged perpendicularly to each other. At the end of each set of screw and nut structures, a second bevel gear 30 is installed that meshes with the first bevel gear 40.

[0055] During operation, when the first bevel gear 40 is driven to rotate, it drives the second bevel gear 30 to rotate synchronously due to the meshing transmission characteristics between the first bevel gear 40 and the second bevel gear 30. Since the second bevel gear 30 is mounted on the end of the lead screw 31, it drives the lead screw 31 to rotate. During the rotation of the lead screw 31, the nut 32 that meshes with it will make linear sliding movements on the lead screw 31 according to the motion principle of the lead screw and nut structure. The linear sliding of the nut 32 ultimately drives the clamping member 6 connected to the nut 32 to make linear movements, thereby completing the clamping or releasing operation of the material.

[0056] The clamping and holding mechanism 5 may include a fixing pin, one end of which can be inserted into the first bevel gear 40 and the other end into the material box cover 2, thereby locking and fixing the first bevel gear 40. Of course, the clamping and holding mechanism 5 may also be a first damping structure, and a damping sleeve may be selected, which is set at the corresponding position of the material box cover 2 and sleeved on the bottom of the first bevel gear 40, aiming to provide a stable damping force when the first bevel gear 40 is running.

[0057] As in Option 2, Figure 11 As shown, the design of the drive assembly 4 and the linkage assembly 3 can be referenced from the design of the four-jaw clamping mechanism. For example, the drive assembly 4 is a rotating disk 41 with four arc-shaped grooves. The linkage assembly 3 includes four cross-shaped slide rails 33 arranged on the material box cover 2, slide rods 34 slidably mounted on the slide rails 33, and guide rods 35 vertically mounted on the slide rods 34. The guide rods 35 are placed in the corresponding arc-shaped grooves and move along the direction of the arc-shaped grooves. The clamping member 6 is fixedly mounted on the outer end of the slide rod 34.

[0058] During operation, when the rotating disk 41 is driven to rotate, the arc-shaped groove on the rotating disk 41 forces the guide rod 35 to drive the slide rod 34 to slide on the slide rail 33, thereby realizing the linear movement of the clamping member 6.

[0059] For example, Option 3, Figures 1 to 8 As shown, the drive component 4 includes a gear 42.

[0060] The linkage assembly 3 includes an L-shaped rack arm 36, which has a horizontal part and a vertical part. The horizontal part of the L-shaped rack arm 36 is provided with a rack that meshes with the gear 42. The end of the vertical part of the L-shaped rack arm 36 is fixedly connected to the clamping member 6. During operation, the rotating gear 42 drives the L-shaped rack arm 36 and the clamping member 6 to move linearly.

[0061] Specifically, four L-shaped rack arms 36 are provided. The four L-shaped rack arms 36 are divided into two groups. The two arms in each group are centrally symmetrically arranged on both sides of the gear 42. The movement directions of the two arms are parallel and opposite to each other, and they are slidably installed on the material box cover 2.

[0062] One set of L-shaped rack arms 36 is arranged along the length of the material box cover 2, and the other set of L-shaped rack arms 36 is arranged along the width of the material box cover 2; the two sets of L-shaped rack arms 36 are staggered in the axial direction of the gear 42.

[0063] It should be noted that the present invention does not limit the implementation method of sliding the L-shaped rack arm 36 on the material box cover 2. It can be designed and selected by those skilled in the art according to the actual situation. For example, a corresponding sliding groove can be set on the material box cover 2, and a slider can be provided on the horizontal part of the L-shaped rack arm 36. The slider is slidably installed in the sliding groove, thereby realizing the sliding installation of the L-shaped rack arm 36 on the material box cover 2.

[0064] During operation, the gear 42 of the drive component rotates and meshes with the rack on the horizontal part of the L-shaped rack arm 36, converting rotational motion into linear motion. Two sets of L-shaped rack arms 36 are staggered, with the racks extending perpendicularly, and are symmetrically distributed around the gear 42. Rotating the gear 42 drives the clamping member 6 to move linearly, achieving material clamping and release through forward and reverse rotation. When the clamping member 6 clamps the battery cell 8, it effectively limits the shaking of the battery cell 8. Even if it encounters vibration and bumps during transportation, the battery cell 8 will be firmly restrained by the clamping member 6, preventing it from impacting the inner wall of the material box, thus avoiding damage and microcracks caused by impact and ensuring the integrity of the battery cell 8 during transportation.

[0065] Of course, only two L-shaped rack arms 36 can be installed, i.e., only one set of L-shaped rack arms 36. With this single set of L-shaped rack arms 36 configuration, unidirectional clamping of materials can be achieved. However, compared to equipping two sets of L-shaped rack arms 36 simultaneously to achieve bidirectional clamping of materials, unidirectional clamping is less stable and comprehensive, resulting in a relatively weaker clamping effect.

[0066] In this embodiment, the clamping and holding mechanism can refer to the design of the previous fixing pin and can adopt the design of a damping sleeve. Preferably, the design of a damping sleeve is adopted to increase the damping friction.

[0067] It should be noted that, preferably, the gear and rack structure design in Scheme 3 is adopted, which has low manufacturing cost and high transmission efficiency. However, this utility model does not limit the specific driving power source of the drive component 4; it can be driven by a motor or manually. In this embodiment, it is manually driven, and correspondingly, a rotating handle 43 is provided on the top of the gear 42 for easy manual operation.

[0068] Furthermore, in some specific embodiments, such as Figure 5 As shown, the first damping structure includes a damping sleeve made of damping material, which is installed at the connection between the material box cover 2 and the drive assembly 4. It should be noted that in this embodiment, the damping material is a material with a high damping coefficient, such as rubber, polyurethane, or viscoelastic polymer materials.

[0069] During the operation of the drive assembly 4, the gear 42 rotates to drive the L-shaped rack arm 36, which in turn drives the clamping member 6 to move. The first bevel gear 40 rotates, and the linkage screw nut structure causes the clamping member 6 to move. For example, since the damping sleeve is installed at the connection between the material box cover 2 and the drive assembly 4, the moving parts of the drive assembly 4 will come into contact with the damping sleeve and form relative motion.

[0070] Damping materials inherently possess the property of hindering relative motion of objects. When the drive assembly 4 drives the clamping member 6 to move via the linkage assembly 3, the resistance generated by the damping sleeve can effectively suppress the movement speed, making the movement of the clamping member 6 smoother and avoiding excessive clamping force caused by rapid movement, as well as impact on the material.

[0071] After the material clamping action is completed, the damping sleeve continues to play its role. The resistance it generates can effectively counteract external vibration or inertial force, prevent the drive component 4 from accidentally retracting, thereby ensuring that the clamping component 6 always remains in a fixed state and ensuring the stability of material clamping.

[0072] When the reverse operation drive component 4 releases the material, the resistance provided by the damping sleeve can slow down the release speed, prevent the clamping part 6 from popping open instantly, and thus prevent the material from being displaced or damaged due to the rapid rebound of the clamping part.

[0073] Of course, this utility model can also utilize a second damping structure to dampen and constrain the linkage component 3, i.e., the L-shaped rack arm 36. It should be noted that the specific structure of the second damping structure is not limited in this utility model, as long as it can achieve damping and constraining of the linkage component 3. For example, a damping strip made of damping material can be used, which is installed on the inner wall of the moving channel 22 to increase the damping force between the L-shaped rack arm 36 and the material box cover 2.

[0074] Furthermore, in some specific embodiments, such as Figure 7 , 8 As shown, the material box base 1 can be provided with an inflation port 10 and a gas channel 11 communicating with the inflation port 10. The outlet of the gas channel 11 is oriented towards the material inside the cavity, and the airflow separates adjacent materials to form gaps. Specifically, the inflation port 10 is used to connect to an external gas source, which is preferably an inert gas such as high-pressure nitrogen. When the external gas source is turned on, the high-pressure airflow is sprayed from the gas channel 11 into the cavity, directly acting on the contact surface of adjacent materials. With the help of gas pressure and the thrust generated by the airflow, a slight separation effect can be achieved between the materials. For example, the gap between the solar cells 8 can be increased to about 0.1mm to 0.5mm. In this way, direct contact between materials can be effectively avoided, thereby preventing damage caused by mutual friction. Especially for the transportation of ultra-thin photovoltaic solar cells 8 and other fragile materials, the probability of defects such as microcracks and scratches can be significantly reduced, greatly improving the protection performance of the materials.

[0075] It should be noted that in this utility model, there are no specific limitations on the number of air inlets 10 or the form of the gas channel 11. For example, the gas channel 11 can be a slit channel or a multi-hole channel. The specific form can be designed and selected by those skilled in the art based on the actual situation.

[0076] In this embodiment, eight air inlets 10 are located at the bottom of the material box base 1. These eight air inlets 10 are divided into four groups, located at the four corners of the material box base 1, allowing high-pressure airflow to act evenly on the material stacking area from multiple directions. Taking the transportation of battery cells 8 as an example, the airflow blown from the four corners converges in the gaps between the materials, avoiding uneven airflow coverage and ensuring that the gaps between each battery cell 8 can be effectively opened, achieving all-round, dead-angle-free material separation and significantly reducing the rate of defects such as microcracks or scratches caused by local friction. Correspondingly, the gas channel 11 adopts a slit-type channel form and extends along the height direction of the material box base 1, ensuring that the airflow ejected from the slit-type channel can evenly cover the gap area formed by the material stacking, maximizing the effect of airflow separating materials and improving the protection effect on the materials.

[0077] Furthermore, in some specific embodiments, such as Figure 4 As shown, each side wall of the material box cover 2 can be provided with a moving channel 22, and the clamping member 6 is placed in the moving channel 22, which provides a moving path for the clamping member 6. At the same time, a limiting baffle 20 is provided on the side of the moving channel 22 near the inside of the cavity. The limiting baffle 20 is used to limit the moving range of the linkage component 3. Specifically, moving channels 22 and corresponding limiting baffles 20 are provided on the four side walls of the material box cover 2 to limit the moving range of the L-shaped rack arm 36, nut 32 and slide bar 34, etc., to prevent the linkage component 3 from moving excessively and to avoid excessive pressure on materials such as battery cells 8 due to excessive movement. In this utility model, the specific shape, size and installation position of the limiting baffle 20 are not limited, and can be designed and selected by those skilled in the art according to the actual situation.

[0078] Furthermore, in some specific embodiments, such as Figure 1 , 6 As shown in Figure 7, a magnetic head 12 can be provided on one of the material box base 1 and the material box cover 2, and a magnetic seat 21 that cooperates with the magnetic head 12 can be provided on the other. The magnetic head 12 and the magnetic seat 21 are used to lock the material box when it is closed. In this embodiment, magnetic heads 12 are provided at the four corners of the material box base 1, and magnetic seats 21 corresponding to the magnetic heads 12 are provided at the four corners of the lower surface of the material box cover 2. By attracting the magnetic heads 12 and the magnetic seats 21, the locking and fixing between the material box base 1 and the material box cover 2 is realized, ensuring that the material box base 1 and the material box cover 2 are tightly fitted during the transportation of the material box and will not have relative displacement, thus protecting the battery cells 8 inside the material box.

[0079] Meanwhile, the material box cover 2 and the material box base 1 are magnetically locked, which can be quickly opened and closed whether operated manually or by automated equipment, improving the efficiency and convenience of operation.

[0080] Of course, a snap-locking structure or a plug-in locking structure can also be provided between the material box base 1 and the material box cover 2 to achieve locking and fixing between the material box base 1 and the material box cover 2.

[0081] Furthermore, in some specific embodiments, such as Figure 8 As shown, an electronic identification module 13 can be installed at the bottom of the material box base 1. The electronic identification module 13 is used to store and transmit material information. Specifically, the electronic identification module 13 can be an RFID chip, which can efficiently transmit key information such as batch number, incoming material information, process information, efficiency information, and classification information. Compared with traditional packaging methods, the electronic identification module 13 significantly improves efficiency and traceability performance, while avoiding the use of materials such as cardboard boxes, labels, and wrapping materials, effectively reducing costs and realizing paperless and intelligent management of material information.

[0082] Furthermore, in some specific embodiments, such as Figure 6 As shown, a buffer layer 60 can be provided on the side of the clamping member 6 near the cavity. Providing a buffer material, such as a flexible material like a rubber pad, on the contact surface between the clamping member 6 and the material can reduce direct mechanical impact on brittle materials (such as photovoltaic cells), lowering the possibility of material damage. Simultaneously, the first damping structure provides buffering during clamping and release, preventing instantaneous impact forces and significantly reducing the risk of microcracks or breakage in the material, thus providing excellent protection.

[0083] This utility model uses the gear and rack structure design in Scheme 3 as an example to illustrate the working process of the conveying box.

[0084] 1) Installation and Connection: Install the material box base 1 on the workbench 7. The workbench 7 is equipped with several inflation ports 70 that correspond one-to-one with the inflation ports 10 of the material box base 1, such as... Figure 9 As shown. The top of the inflation interface 70 has a sloping structure, which facilitates the docking operation. Insert the inflation port 10 of the material box base 1 into the corresponding inflation interface 70 to complete the docking.

[0085] 2) Material Loading and Box Closure: Place the battery cells 8 and other materials into the box base 1, then place the box cover 2 on top of the box base 1. Utilize the magnetic locking structure to ensure the box cover 2 is tightly locked to the box base 1, preventing accidental detachment during transportation. At this time, the damping clamping mechanism on the box cover 2 is in a relaxed state and has not yet clamped the battery cells 8. Figure 2 As shown.

[0086] 3) Separation and clamping of battery cells 8: The control table 7 releases nitrogen gas at a pressure of 5 MPa through the inflation port 70. The nitrogen gas is ejected sequentially through the inflation port 70, the inflation port 10 of the material box base 1, and the gas channel 11, causing slight separation of the battery cells 8 inside the material box. Simultaneously, the operator rotates the handle 43 to turn the gear 42, driving the damping clamping mechanism to operate. This causes the material box cover 2 to gradually change the clamping member 6 from a relaxed state to a tightened state, achieving the clamping operation of the battery cells 8. Figure 3 As shown. During this process, the battery cells 8 will not be damaged by mutual friction, thus providing good protection.

[0087] 4) Transportation and Retrieval: After completing the above operations, the preparation work for the transfer box at the battery end is finished. Control workbench 7 stops inflating the inflation port 70 and moves the transfer box to the module end. Upon arrival at the module end, first loosen the box cover 2 to return it to its relaxed state, then separate the box cover 2 from the box base 1. Move the box base 1 containing the battery cells 8 to the material loading position on the stringer for retrieval.

[0088] 5) Material box reset and circulation: After material retrieval is completed, the material box cover 2 is placed back on the material box base 1 to ensure a tight fit. Then, the material box is moved back to the battery end to prepare for the next transfer of battery cells 8.

[0089] Based on the aforementioned conveyor box, this invention also provides a photovoltaic module production system, which includes the aforementioned conveyor box. The photovoltaic module production system provided by this invention encompasses all the technical solutions of all embodiments of the aforementioned conveyor box, and therefore possesses at least all the beneficial effects brought about by the technical solutions of the aforementioned conveyor box embodiments, which will not be elaborated upon here.

[0090] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
