Description

Technical Field

[0001] The utility model relates to the technical field of silicon wafer transportation, in particular to a full material box taking device. Background Art

[0002] In the process of manufacturing crystalline silicon solar cells, silicon wafers are needed, and the silicon wafers need to be plastic-sealed. When performing the plastic sealing operation on silicon wafers, the silicon wafers need to be taken out of the material box for adjustment, and then placed in the plastic sealing machine.

DETAILED DESCRIPTION

[0027] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0028] In the description of the present invention, it should be understood that the descriptions involving orientation, such as the orientation or positional relationship indicated as up, down, etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0029] In the description of the present utility model, "a plurality" means more than two. If there is a description of "first" or "second", it is only for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] In the present invention, the material in the material box generally refers to the silicon wafers used to manufacture crystalline silicon solar cells, and of course it can also refer to similar sheet materials and easily damaged materials; a full material box generally refers to a material box full of materials, that is, a material box full of silicon wafers. In the related art, the material in the material box is transported by picking up the material with a robot and then taking it out directly. This way of transporting the material will cause the material to contact and scratch the material box, causing damage to the material.

[0032] Reference Figure 1As shown, a full material box picking device of an embodiment of the utility model includes a driving mechanism 100 and a clamping mechanism 200. The driving mechanism 100 has a first moving axis arranged along the X direction, a second moving axis arranged along the Z direction, and a third moving axis, the angle between the third moving axis and the X direction is an acute angle, and the third moving axis is perpendicular to the Z direction, wherein the X and Z directions are perpendicular to each other; the clamping mechanism 200 is arranged on the driving mechanism 100, and the clamping mechanism 200 is used to pick up the material in the material box. By picking up the material through the full material box picking device of the embodiment of the utility model, the material (silicon wafer) can be transported without scratching the material box, thereby avoiding material damage, and the transportation efficiency is high.

[0033] Let the direction perpendicular to both the X direction and the Z direction be the Y direction, that is, the X, Y, Z coordinate system. The angle between the third movable axis and the X direction is an acute angle rather than a right angle. When the clamping mechanism 200 moves along the third movable axis set in this way, the position of the clamping mechanism 200 in the X direction and the Y direction can be changed at the same time. For example, the adjacent two sides of the silicon wafer in the material box are in contact with the side walls of the material box. When the clamping mechanism 200 picks up the silicon wafer and moves along the third movable axis, it can control the silicon wafer to change the position in the X direction and the Y direction at the same time, that is, the two sides of the silicon wafer are away from the side walls of the material box at the same time. The subsequent movement of the clamping mechanism 200 along the second movable axis can remove the silicon wafer from the material box without scratching, thereby avoiding damage to the silicon wafer.

[0034] If the third moving axis is directly arranged along the Y direction, in this case, no matter whether the clamping mechanism 200 moves along the first moving axis (X direction) or the third moving axis (Y direction) first, one side of the silicon wafer will definitely contact and move with the material box. It is understandable that the clamping mechanism 200 can be programmed to move along the X direction and the Y direction at the same time, but to achieve simultaneous movement, the control system has higher requirements, the control program is more complicated, and there is a certain delay in the movement of the X direction and the Y direction that cannot be eliminated.

[0035] Compared with the above situation, in the embodiment of the present utility model, referring to Figure 2 As shown, the third moving axis is set to form an acute angle with the X direction, which does not require a complex control system and can move in the X direction and the Y direction simultaneously without delay, thereby avoiding scratches between the silicon wafer and the material box.

[0036] In the embodiment of the utility model, the clamping mechanism 200 can be a claw-type silicon wafer clamping device, which can clamp a single silicon wafer or multiple silicon wafers at the same time; of course, it can also be a suction cup-type structure to absorb silicon wafers, so there is no further restriction on the clamping mechanism 200.

[0037] The driving mechanism 100 can be arranged in a variety of ways.

[0038] It can be understood that the driving mechanism 100 of the first embodiment includes a first driving rail 110, a second driving rail 120 and a third driving rail 130, the first driving rail 110 is arranged along the X direction, the second driving rail 120 is arranged along the Z direction and is slidably connected to the first driving rail 110, the third driving rail 130 is arranged perpendicular to the second driving rail 120, the angle between the third driving rail 130 and the first driving rail 110 is an acute angle, and the third driving rail 130 is slidably connected to the second driving rail 120, and the clamping mechanism 200 is slidably connected to the third driving rail 130.

[0039] First, a driving rail in the X direction, i.e., the first driving rail 110, is set, and then a second driving rail 120 in the Z direction is set, and the third driving rail 130 can be driven to move in the X direction and the Y direction, so that the clamping mechanism 200 can move in the space to pick up the silicon wafers in the material box. The first driving rail 110, the second driving rail 120, and the third driving rail 130 all include a structure for providing power and a structure for guiding. For specific structures, reference can be made to other embodiments of the present invention.

[0040] It can be understood that the driving mechanism 100 of the second embodiment includes a fourth driving rail, a fifth driving rail and a sixth driving rail, the fourth driving rail is arranged along the Z direction, the fifth driving rail is arranged along the X direction and is slidably connected to the fourth driving rail, the sixth driving rail is arranged perpendicular to the fourth driving rail, the angle between the sixth driving rail and the fifth driving rail is an acute angle, and the sixth driving rail is slidably connected to the fifth driving rail, and the clamping mechanism 200 is slidably connected to the sixth driving rail.

[0041] Compared with the first embodiment, the second embodiment first sets the fourth driving rail in the Z direction, and then sets the fifth driving rail in the X direction, that is, the order of setting the driving rails in the X direction and the Z direction is different, which can be adjusted according to the space limitations of the device.

[0042] Reference Figure 3 As shown, it can be understood that the first drive rail 110 includes a first mounting member 111, and the first mounting member 111 is provided with two transmission shafts 112 spaced apart along the X direction, and a synchronous belt 113 is installed between the two transmission shafts 112, one of the transmission shafts 112 is connected to the first motor 114, and the second drive rail 120 is slidably connected to the first mounting member 111, and the synchronous belt 113 is connected to the second drive rail 120.

[0043] The first mounting member 111 serves as the installation base of the first driving rail 110, and is used to set the transmission shaft 112, the synchronous belt 113 and the first motor 114. The synchronous belt 113 is mounted on the two transmission shafts 112, and the first motor 114 only needs to be connected to one of the transmission shafts 112 and driven to rotate, so as to drive the synchronous belt 113 to move. The second driving rail 120 is connected to the synchronous belt 113, and the movement in the X direction is transmitted to the second driving rail 120, so that the clamping mechanism 200 can finally move in the X direction. The synchronous belt 113 has teeth, which mesh with the teeth on the transmission shaft 112 to avoid slipping, so that the movement control of the first driving rail 110 is more precise, and the driving ability is also stronger.

[0044] Reference Figure 4 As shown, it can be understood that the first mounting member 111 is further provided with an adjustment plate 115 , and the adjustment plate 115 is detachably connected to the first mounting member 111 , wherein one transmission shaft 112 is disposed on the adjustment plate 115 .

[0045] The transmission shaft 112 is arranged on the adjustment plate 115. By changing the position of the adjustment plate 115 on the first mounting member 111, the distance between the transmission shaft 112 and another transmission shaft 112 can be adjusted, thereby adjusting the tension of the synchronous belt 113. This can facilitate the installation of the synchronous belt 113 on the transmission shaft 112 and adjust the synchronous belt 113 to work within a suitable tension range.

[0046] The adjustment plate 115 can be detachably connected to the first mounting member 111 by bolt connection, but is not limited to this connection method.

[0047] It can be understood that the first mounting member 111 is provided with a first fixing block 116, the adjustment plate 115 is provided with a second fixing block 117, the first fixing block 116 is inserted with an adjusting bolt 118, and the adjusting bolt 118 is screwed into the second fixing block 117, and the adjusting bolt 118 can control the distance between the first fixing block 116 and the second fixing block 117.

[0048] The adjusting bolt 118 can assist in adjusting the position of the adjusting plate 115, thereby reducing the difficulty of adjusting the adjusting plate 115. Since the first fixing block 116 is fixed on the first mounting member 111, when the adjusting bolt 118 rotates, the adjusting bolt 118 and the second fixing block 117 are driven to drive the second fixing block 117 to move the adjusting plate 115. The transmission shaft 112 on the adjusting plate 115 is sleeved with a synchronous belt 113, and the tension of the synchronous belt 113 makes it difficult to move the adjusting plate 115. By assisting in moving the adjusting plate 115 with the adjusting bolt 118, the difficulty of adjusting the adjusting plate 115 can be reduced.

[0049] Reference Figure 5As shown, it can be understood that the second drive rail 120 includes a second mounting member 121, and the second mounting member 121 is provided with a screw rod 122 along the Z direction, the screw rod 122 is connected to a second motor 123 and a sleeve 124, the second motor 123 is used to drive the screw rod 122 to rotate, the sleeve 124 is mounted on the screw rod 122 to move, and the third drive rail 130 is connected to the sleeve 124.

[0050] The Z direction is generally the moving direction of the silicon wafer when it is taken out of the material box, and the placing moving direction of the silicon wafer when it is placed. Compared with the large-scale movement and rapid positioning in the horizontal plane, the movement amount in the Z direction is not large, and requires higher precision control, so the transmission of the screw rod 122 and the sleeve 124 is used to drive the third driving rail 130 to move, that is, to drive the clamping mechanism 200 to move in the Z direction. The second motor 123 is used to provide power for the rotation of the screw rod 122. Of course, the specific structure of the second driving rail 120 is not limited to the screw rod and sleeve transmission.

[0051] Reference Figure 6 As shown, it can be understood that the clamping mechanism 200 includes a connecting plate 210, and a plurality of clamping jaw assemblies 220 are arranged around the connecting plate 210. The clamping jaw assemblies 220 can be retracted inwardly to clamp the material.

[0052] The plurality of clamping claw assemblies 220 can be retracted inwards to surround and clamp the silicon wafer. Compared with the suction cup structure to suck the silicon wafer, the clamping claw assemblies 220 can clamp multiple stacked silicon wafers at a time, and the efficiency of carrying the silicon wafers is higher.

[0053] It can be understood that one of the structures of the clamping jaw assembly 220 includes a clamping jaw plate 221 and a driving member 222, wherein the clamping jaw plate 221 is arranged around the connecting plate 210, and the driving member 222 is connected to the clamping jaw plate 221, and the driving member 222 can drive the clamping jaw plate 221 to contract inwardly and expand outwardly.

[0054] Each clamping plate 221 can be driven by a separate driving member 222. Of course, two opposing clamping plates 221 can also be driven by one driving member 222, that is, the driving member 222 drives the two opposing clamping plates 221 to move closer to each other so as to shrink inwards and clamp the silicon wafer.

[0055] Reference Figure 7 As shown, it can be understood that a specific driving member 222 structure includes a cylinder 223 and a push-pull rod 224, the push-pull rod 224 is arranged in the cylinder 223, the push-pull rod 224 is connected to the clamping claw plate 221, and the cylinder 223 can drive the push-pull rod 224 to move to drive the clamping claw plate 221 to move.

[0056] The cylinder 223 is a commonly used driving member. The cylinder 223 has a piston inside. The pressure difference on both sides of the piston can control the moving direction of the piston. The push-pull rod 224 only needs to be connected to the piston set in the cylinder 223, which can drive the push-pull rod 224 to move and drive the clamping plate 221 connected to the push-pull rod 224 to move. It should be understood that the end of the clamping plate 221 can also be provided with a supporting member made of soft material, and the supporting member is perpendicular to the clamping plate 221. The clamping plate 221 contacts the side of the silicon wafer to clamp the silicon wafer, and the supporting member can support the surface of the silicon wafer to assist in clamping the silicon wafer.

[0057] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
