Description

Technical Field

[0001] The present invention relates to the technical field of finished solar cell packaging, and in particular to a stacking box for solar cell packaging and a loading and unloading device for solar cell packaging. Background Art

[0002] With the gradual reduction of fossil energy and the improvement of public environmental awareness, the promotion and popularization of clean energy are becoming more and more widespread, such as hydrogen energy, wind energy, nuclear energy, solar energy, etc.

[0003] During the production process of solar cells, the solar cells need to be picked up, tested, and packaged. During this process, the solar cells need to be placed in a dedicated stacking box first. The stacking box is divided into a lower box and an upper box. Then, the robot takes out the cells from the lower box according to a preset program or manually and places them in the upper box.

[0004] The existing stacking box for solar cells can accommodate both loading and unloading functions. However, when unloading solar cells from the stacking box, there are problems such as the inability to stack them neatly and the friction causing fragments and scratches, which will have a significant impact on subsequent loading. Utility Model Content

[0005] Based on this, it is necessary to provide a stacking box for solar cells and a loading and unloading device for solar cells, which solves the problem that the cells cannot be stacked neatly when unloading from the stacking box and are broken and scratched due to friction.

[0006] The embodiment of the present disclosure provides a stacking material box for solar cell sheets, the stacking material box for solar cell sheets comprises a base, a plurality of limit members and a lifting assembly; the base is arranged horizontally and a support member is convexly arranged on the upper surface of the base; the plurality of limit members are connected to the upper surface of the base, the plurality of limit members extend vertically and enclose a receiving space with the base, the support member is located in the receiving space and is close to at least one limit member, at least one limit member close to the support member is provided with a blowing device, and the blowing device faces the receiving space; the lifting assembly comprises a lifting member and a lifting plate, the lifting member is movably mounted on the middle part of the base, the lifting member has a material unloading position lower than the support member and a material loading position higher than the support member, and the lifting plate is accommodated in the receiving space; wherein, when the lifting member is in the material unloading position, one end of the lifting plate is located above the support member, and the other end of the lifting plate abuts against the base, so that the lifting plate is inclined relative to the base and forms an inclination angle, and the blowing device is higher than the upper surface of the lifting plate; when the lifting member is in the material loading position, the lifting plate is connected to the lifting member and is parallel to the base.

[0007] The stacking box for solar cells provided in the embodiment of the present disclosure has a supporting member that plays a supporting role within the accommodating space, and when the lifting member is in the unloading position, the lifting plate is tilted relative to the base. When unloading, the solar cells will slide in the inclined direction due to the effect of gravity, and the limiting member has a certain limiting effect on the solar cells, so that the solar cells are stacked neatly under the effect of gravity; on the other hand, the blowing device on the limiting member reduces the friction of the solar cells during the sliding process, reduces the scratches and fragments caused by the friction between the solar cells, and finally assists all the solar cells to be neatly stacked to the same position, which is convenient for the subsequent loading of the solar cells.

[0008] In some of the embodiments, the stacking box for solar cells also includes a wind knife, and the wind knife is connected to the side of the upper end of the limiting member facing away from the accommodating space. The wind knife is provided with an air outlet, and the air outlet is located on both sides of the limiting member in the horizontal direction, and the wind direction of the air outlet is toward the accommodating space.

[0009] With such arrangement, when the lifting member is in the loading position, a plurality of parallel solar cells are stacked on the lifting plate. After the wind knife is turned on, the blowing part blows air toward the solar cells to separate the stacked solar cells, making it convenient for a robot or manual person to take the solar cells.

[0010] In some of the embodiments, when the lifting member is in the loading position, the position of the air outlet is higher than the upper surface of the lifting plate.

[0011] Such an arrangement enables the wind from the air outlet to be directed directly toward the solar cells on the lifting plate, thereby reducing scratches caused by friction between the solar cells and facilitating the use of the solar cells.

[0012] In some embodiments, the lifting member includes a lifting part and a positioning part protruding from the upper surface of the lifting part. The lifting plate and the positioning part corresponding to the part are provided with a positioning hole. The shape of the positioning hole matches the shape of the positioning part. The positioning part and the positioning hole can be docked and matched so that the lifting drive member drives the lifting plate to rise and fall relative to the base.

[0013] With such arrangement, the lifting member moves upward until the positioning part enters the positioning hole, thereby driving the lifting plate to rise and leave the supporting member so that the lifting plate changes from an inclined state to a horizontal state. The positioning hole of the positioning part has a simple matching structure, which makes it convenient for the lifting member to drive the lifting plate to switch between the loading position and the unloading position.

[0014] In some embodiments, after the positioning portion is docked with the positioning hole, the upper surface of the positioning portion is lower than the upper surface of the lifting plate.

[0015] Such arrangement prevents the solar cell sheets from being lifted up by the upper surface of the positioning portion, thereby ensuring the neatness of the stacked solar cell sheets when the lifting plate is raised.

[0016] In some of the embodiments, the distance between the top surface of the support and the base is adjustable; the tilt angle ranges from 10° to 40°.

[0017] Such an arrangement makes it easy to adjust the inclination angle of the support plate by adjusting the height of the support member, and facilitates the adjustment of the uniformity of the unloading of different types of solar cells.

[0018] In some embodiments, the base is square in shape, has four sides, and at least one limiting member is disposed corresponding to one side.

[0019] With such an arrangement, the four limiting members corresponding to the four side edges limit the support plate and the solar cell in the horizontal direction, thereby preventing the solar cell from being offset in the horizontal direction and preventing the four corners of the solar cell from colliding with the limiting members, thereby reducing damage to the solar cell when unloading.

[0020] In some embodiments, a plurality of grooves are formed on the upper surface of the base, and the lower end of a limiting member is correspondingly engaged with a groove.

[0021] With such arrangement, the lower end of the limiting member is clamped in the groove to ensure the connection firmness and position accuracy between the limiting member and the base.

[0022] In some embodiments, a plurality of limiting grooves are formed on the edge of the lifting plate, and at least one limiting member is engaged in a limiting groove.

[0023] With such arrangement, the limiting member can be correspondingly engaged with the limiting groove, and the lifting plate can also partially extend out of the accommodating space formed by the plurality of limiting members, thereby preventing the lifting plate from being offset in the horizontal direction and facilitating the lifting member to drive the lifting plate to move upward and downward.

[0024] The disclosed embodiment provides a loading and unloading device for solar cells, comprising the above-mentioned stacking box for solar cells, a driving member and a manipulator, wherein the driving member is used to drive the lifting component to lift; when the lifting member is in the loading position, the manipulator is used to grab the solar cells and place them on the lifting plate; when the lifting member is in the unloading position, the manipulator is used to suck the solar cells on the lifting plate.

[0025] The stacking box of solar cells of the loading and unloading device of solar cells provided in the embodiment of the present disclosure can have both loading and unloading functions. When unloading, the solar cells are stacked neatly by relying on gravity while reducing scratches and fragments caused by friction between the solar cells. After being stacked neatly, the solar cells are lifted to the loading position by the lifting assembly for loading; the robot arm facilitates the loading and unloading of solar cells by the stacking box of solar cells, reduces the fragments and scratches of solar cells caused by human intervention, and improves the yield rate of products.

[0036] refer to Figure 1 , Figure 1 The front view of the structure of the stacking material box 10 of the solar cell sheets in the embodiment of the present disclosure when unloading is shown. The present disclosure relates to the technical field of finished solar cell sheet packaging.

[0037] Combination Figure 2 The embodiment of the present disclosure provides a stacking box 10 for solar cells. The stacking box 10 for solar cells includes a base 1, a plurality of stoppers 2, and a lifting assembly 3. The base 1 is arranged in a horizontal direction. A support member 4 is convexly provided on the upper surface of the base 1.

[0038] A plurality of stoppers 2 are vertically connected to the upper surface of the base 1, and the plurality of stoppers 2 extend upward and enclose a receiving space 21 with the base 1. Exemplarily, the stoppers 2 are located at the edge of the base 1. The support member 4 is located in the receiving space 21 and is close to at least one stopper 2. Exemplarily, the support member 4 is close to the stopper 2 on the left side. At least one stopper 2 close to the support member 4 is provided with a blowing device 5, and the blowing device 5 faces the receiving space 21.

[0039] The lifting assembly 3 includes a lifting member 31 and a lifting plate 32. The lifting member 31 is movably mounted on the middle portion of the base 1, and the lifting plate 32 is accommodated in the accommodating space 21 and is located above the lifting member 31. The lifting member 31 has a material unloading position lower than the support member 4 and a material loading position higher than the support member 4.

[0040] Among them, when the lifting member 31 is in the unloading position, one end of the lifting plate 32 is located above the support member 4, and the other end of the lifting plate 32 abuts against the base 1, so that the lifting plate 32 is tilted relative to the base 1 and forms an inclination angle, and the blowing device 5 is higher than the upper surface of the lifting plate 32. Exemplarily, the lower surface of the left end of the lifting plate 32 abuts against the upper surface of the support member 4, and the lower surface of the right end of the lifting plate 32 abuts against the upper surface of the base 1. Exemplarily, the blowing device 5 is located on the left stopper 2 and is higher than the upper surface of the left end of the lifting plate 32. The angle formed by the lower surface of the lifting plate 32 and the upper surface of the base 1 is the inclination angle. When the lifting member 31 is in the loading position, the lifting plate 32 is connected to the lifting member 31 and is parallel to the base 1. Exemplarily, the loading position is close to the upper end of the stopper 2.

[0041] In the stacking material box 10 of solar cells provided in the embodiment of the present disclosure, the support member 4 plays a supporting role in the accommodating space 21, and when the lifting member 31 is in the unloading position, the lifting plate 32 is tilted relative to the base 1. When unloading, the solar cells will slide in the inclined direction due to the effect of gravity, so that the solar cells are close to the limit member 2 where the inclination angle is located. On the other hand, the blowing device 5 on the limit member 2 reduces the friction of the solar cells during the sliding process.

[0042] The stacking material box 10 of solar cells provided in the embodiment of the present disclosure has a limiting member 2 that limits the solar cells to a certain extent and cooperates with the inclined support plate to enable the solar cells to be stacked neatly under the action of gravity; the blowing device 5 reduces scratches and fragments caused by friction between the solar cells, and finally assists in stacking all the solar cells neatly to the same position, which is convenient for the subsequent loading of the solar cells.

[0043] refer to Figure 1For example, the blowing device 5 is provided with a plurality of air holes, which are arranged horizontally and connected to the accommodating space 21, and the blowing device 5 blows air to the solar cell through the air holes. For example, each stopper 2 is provided with a blowing device 5.

[0044] Exemplarily, the shape of the limiting member 2 is a strip. The size of the accommodating space 21 surrounded by the multiple limiting members 2 matches the size of the solar cell, and the multiple limiting members 2 perform a limiting operation on the solar cell. In other embodiments, the shape of the limiting member 2 can also be a cylinder, a triangular prism or other shapes.

[0045] refer to Figure 1 and Figure 2 In some embodiments, the base 1 is square in shape, has four sides, and at least one limiting member 2 is disposed corresponding to one side.

[0046] With such arrangement, the four limiting members 2 corresponding to the four sides limit the support plate and the solar cell in the horizontal direction, thereby preventing the solar cell from being offset in the horizontal direction and preventing the four corners of the solar cell from colliding with the limiting members 2, thereby reducing damage to the solar cell when unloading.

[0047] Exemplarily, eight stoppers 2 are symmetrically fixedly arranged on four sides of the base 1, two stoppers 2 are arranged at intervals on each side, and the stoppers 2 on opposite sides are symmetrically arranged. In other embodiments, the number of stoppers 2 can be four, twelve or more.

[0048] In other embodiments, the limiting members 2 may also be located at the corners of the four sides, and the limiting members 2 may be in a right angle shape, or some limiting members 2 may be connected to the corners of the four sides in a right angle shape, and the remaining limiting members 2 may be installed at corresponding positions on the sides.

[0049] In other embodiments, the base 1 may also be in other shapes.

[0050] refer to Figure 1 and Figure 2 In some embodiments, the stacking box 10 for solar cells further includes a wind knife 6, and the wind knife 6 is connected to the side of the upper end of the limiting member 2 facing away from the accommodating space 21, and the wind knife 6 is provided with an air outlet 61, and the air outlet 61 is located on both sides of the limiting member 2 in the horizontal direction, and the wind direction of the air outlet 61 is toward the accommodating space 21.

[0051] With such arrangement, when the lifting member 31 is in the loading position, a plurality of parallel solar cells are stacked on the lifting plate 32. After the wind knife 6 is turned on, the blowing part blows air toward the solar cells to separate the stacked solar cells, making it convenient for the robot 20 or manual labor to take the solar cells.

[0052] Exemplarily, the wind knife 6 is installed on the outside of the limit member 2, and the size of the wind knife 6 along the horizontal direction is larger than the size of the limit member 2 along the horizontal direction. The part of the wind knife 6 that is larger than the limit member 2 is the air outlet 61, and the air outlet 61 is located on both sides of the limit member 2 and blows air toward the solar cell.

[0053] Exemplarily, the upper end of each stopper 2 is equipped with a wind knife 6. In other embodiments, the stoppers 2 that are symmetrically arranged are equipped with wind knives 6. For example, the stoppers 2 that are relatively arranged in the left and right directions are equipped with wind knives 6.

[0054] refer to Figure 2 In some embodiments, when the lifting member 31 is at the loading position, the position of the air outlet portion 61 is higher than the upper surface of the lifting plate 32 .

[0055] Such an arrangement enables the wind from the air outlet 61 to face the solar cells on the lifting plate 32, thereby reducing scratches caused by friction between the solar cells and facilitating the use of the solar cells.

[0056] Exemplarily, the lifting member 31 drives the lifting plate 32 to rise to the loading position, and the upper surface of the lifting plate 32 at the loading position is below the air outlet 61, so that the multiple solar cells stacked on the lifting plate 32 are separated by the wind blown by the air outlet 61, thereby reducing the friction between the solar cells and facilitating the picking up of the solar cells one by one.

[0057] refer to Figure 1 In some embodiments, the lifting member 31 includes a lifting portion 311 and a positioning portion 312 protruding from the upper surface of the lifting portion 311. A positioning hole 321 is provided at a portion of the lifting plate 32 corresponding to the positioning portion 312. The shape of the positioning hole 321 matches the shape of the positioning portion 312. The positioning portion 312 and the positioning hole 321 can be docked and matched so that the lifting drive member 30 drives the lifting plate 32 to rise and fall relative to the base 1.

[0058] With such arrangement, the lifting member 31 moves upward until the positioning portion 312 enters the positioning hole 321, and then drives the lifting plate 32 to rise and leave the support member 4, so that the lifting plate 32 changes from an inclined state to a horizontal state. The positioning hole 321 of the positioning portion 312 has a simple matching structure, which makes it convenient for the lifting member 31 to drive the lifting plate 32 to switch between the loading position and the unloading position.

[0059] Exemplarily, the lifting portion 311 is square, the positioning portion 312 is also cylindrical and fixed on the lifting portion 311, and the projection of the positioning portion 312 along the vertical direction is smaller than the projection of the lifting portion 311 along the vertical direction. The shape and size of the positioning hole 321 match the shape and size of the positioning portion 312.

[0060] In other embodiments, the lifting portion 311 may be cylindrical or in other shapes, and the positioning portion 312 may be square or in other shapes.

[0061] In some embodiments, after the positioning portion 312 is mated with the positioning hole 321 , the upper surface of the positioning portion 312 is lower than the upper surface of the lifting plate 32 .

[0062] This arrangement prevents the solar cells from being lifted up by the upper surface of the positioning portion 312 , thereby ensuring the neatness of the stacked solar cells when the lifting plate 32 is raised.

[0063] Exemplarily, the thickness of the positioning portion 312 is equal to or lower than the thickness of the lifting plate 32 .

[0064] In some of the embodiments, the distance between the top surface of the support member 4 and the base 1 is adjustable; the tilt angle ranges from 10° to 40°. Exemplarily, the length of the support member 4 extending in the front-to-back direction is not greater than the size of the solar cell. Exemplarily, the support member 4 is detachably mounted on the base 1. Different support members 4 have different heights, and replacing different support members 4 can adjust the tilt angle. Exemplarily, the tilt angle can be 10°, 15°, 20°, 25°, 30°, 35° or 40°.

[0065] Such an arrangement makes it easy to adjust the inclination angle of the support plate by adjusting the height of the support member 4, and facilitates the adjustment of the uniformity of the blanking of different types of solar cells.

[0066] refer to Figure 1 and Figure 2 In some embodiments, a plurality of grooves 11 are formed on the upper surface of the base 1 , and the lower end of a stopper 2 is correspondingly engaged with a groove 11 .

[0067] With such arrangement, the lower end of the limiting member 2 is clamped in the groove 11 to ensure the connection firmness and position accuracy between the limiting member 2 and the base 1 .

[0068] Exemplarily, the limiting member 2 is connected to the base 1 by bolts.

[0069] In other embodiments, the limiting member 2 may also be connected to the base 1 by welding, buckling or other methods.

[0070] refer to Figure 1 In some embodiments, a plurality of limiting grooves 322 are formed on the edge of the lifting plate 32 , and at least one limiting member 2 is engaged in a limiting groove 322 .

[0071] With such arrangement, the limiting member 2 can be correspondingly engaged with the limiting groove 322 , and the lifting plate 32 can also partially extend out of the accommodating space 21 formed by multiple limiting members 2 to avoid horizontal deviation of the lifting plate 32 and facilitate the lifting member 31 to drive the lifting plate 32 to rise and fall.

[0072] refer to Figure 1 , exemplarily, the lifting plate 32 is of irregular shape, and two limiting members 2 arranged on the same side of the base 1 are clamped in a limiting groove 322 .

[0073] Exemplarily, the number of the limiting grooves 322 formed on the lifting plate 32 is the same as the number of the limiting members 2 , and the positions of the limiting grooves 322 correspond to the positions of the limiting members 2 .

[0074] In other embodiments, the lifting plate 32 may not have the limiting groove 322 . The lifting plate 32 is square and located inside the accommodating space 21 . The four sides of the lifting plate 32 abut against the inner side surface of the limiting member 2 .

[0075] refer to Figure 1 and Figure 2 In some embodiments, the stacking box 10 of solar cells further includes at least one handle 7, which is fixedly disposed on the base 1 and disposed outside the accommodating space 21 surrounded by the plurality of limit members 2. With such a configuration, the handle 7 facilitates the carrying of the stacking box 10 of solar cells.

[0076] Exemplarily, the stacking box 10 for solar cells includes two symmetrically arranged handles 7, which are arranged on the base 1 outside the accommodating space 21 along the left-right direction. The symmetrical arrangement of the handles 7 prevents the solar cells from being damaged by tilting during transportation.

[0077] refer to Figure 3 The embodiment of the present disclosure provides a loading and unloading device 100 for solar cells, comprising the above-mentioned stacking box 10 for solar cells, a driving member 30 and a manipulator 20, wherein the driving member 30 is used to drive the lifting component 3 to lift; when the lifting member 31 is in the loading position, the manipulator 20 is used to grab the solar cells and put them on the lifting plate 32; when the lifting member 31 is in the unloading position, the manipulator 20 is used to suck the solar cells on the lifting plate 32.

[0078] The stacking box 10 of the solar cell loading and unloading device 100 provided in the embodiment of the present disclosure can accommodate both loading and unloading functions. When unloading, the solar cells are neatly stacked by gravity while reducing scratches and fragments caused by friction between the solar cells. After being neatly stacked, the solar cells are lifted to the loading position by the lifting component 3 for loading; the manipulator 20 facilitates the loading and unloading of solar cells by the stacking box 10 of the solar cells, reduces the fragments and scratches of the solar cells caused by human intervention, and improves the yield rate of the product.

[0079] Exemplarily, the driving member 30 is located under the stacking material box 10 of the solar cell, and the driving member 30 is connected to the lifting member 31 and can drive the lifting member 31 to rise and fall. When the lifting member 31 is lowered to the lowest position, it is the unloading position, the lifting plate 32 is in an inclined state, and the end of the lifting plate 32 abutting against the support member 4 is higher. The manipulator 20 places the grabbed solar cell in the stacking material box. In the process of the solar cell leaving the manipulator 20 and descending, it is affected by the blowing of the blowing device 5 installed at the lower end of the limit member 2, which reduces the friction during the sliding process. When it reaches the lifting plate 32, it slides tiltedly due to gravity and approaches the tilt angle. After the manipulator 20 puts the grabbed solar cells in one by one, multiple solar cells are tilted and stacked neatly. When loading is required, the driving member 30 drives the lifting member 31 to rise so that the positioning part 312 enters the positioning hole 321 and gradually drives the lifting plate 32 and the solar cell to be level. At this time, the solar cells are still neatly stacked until the lifting member 31 rises to the loading position. The wind from the air outlet 61 of the wind knife 6 at the upper end of the limit member 2 separates the stacked solar cells. At this time, the robot 20 sucks the solar cells from the upper side and takes them away, and takes away all the solar cells in turn to complete the loading.

[0080] The technical features of the embodiments disclosed above can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the embodiments described above are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0081] The above disclosed embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
