Description

[0002] The manufacturing of heterojunction solar cells (HJT cells) includes processes such as texturing and cleaning, silicon-based thin film deposition, transparent conductive film deposition, and screen printing. In the texturing and cleaning process, silicon wafers are loaded using a loading basket and transferred to a reagent tank for reaction and a cleaning tank for cleaning by a robotic arm.

[0003] Traditional robotic arms only have one lifting column as support. The robotic arm is in an unbalanced force state for a long time, which is prone to offset. The height of the suspended side of the robotic arm is lower than the connected side, which affects the service life of the robotic arm. Long-term use of an unevenly stressed robotic arm to transfer loading baskets can easily cause the mechanical arm to deform, resulting in different degrees of difference in the force applied by different basket positions of the robotic arm to the loading baskets in different positions, causing deformation and damage of the loading basket, which affects its service life.

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0034] The utility model provides a transport device which can be used for transporting a battery sheet loading basket.

[0035] As shown in FIG. 1 , a handling device 10 according to an embodiment includes a guiding device 100 , a grabbing device 200 , and a grabbing driving device 300 .

[0036] The grabbing device 200 is suspended in pairs on the guide device 100 and can move along the guide device 100. The grabbing device 200 includes a mobile installation mechanism 210, a basket lifting mechanism 220 and a lifting mechanism 230. The mobile installation mechanism 210 is slidably matched with the guide device 100 to realize the overall movement of the grabbing device 200. The lifting mechanism 230 is arranged on the mobile installation mechanism 210 and connected to the basket lifting mechanism 220, and the lifting mechanism 230 is used to drive the basket lifting mechanism 220 to rise and fall. The grabbing driving device 300 is connected to the mobile installation mechanism 210 to drive the mobile installation mechanism 210 to move, thereby driving the basket lifting mechanism 220 to grab the loading basket.

[0037] The above-mentioned handling equipment 10 uses the guiding device 100 to bear the entire weight of the grasping device 200, which improves the problem of uneven force on the conventional robotic arm when the lifting column is used for unilateral support, improves the offset of the grasping device 200, extends the service life of the grasping device 200, and improves the basket lifting effect of the grasping device 200.

[0038] The guide device 100 can be installed above a texturing machine, a cleaning tank, etc., so that the gripping device 200 can pick up and place the loading basket on the corresponding equipment to perform texturing, cleaning, etc. In one example, the guide device 100 is a slide rail. Further, the slide rail extends horizontally.

[0039] The lifting mechanism 230 is used to drive the basket lifting mechanism 220 to rise or fall, so as to realize the transfer of the loading basket in the vertical direction. In one example, the grabbing drive device 300 is a motor screw transmission assembly. The motor screw transmission assembly can flexibly adjust the height of the basket lifting mechanism 220 as needed. More specifically, as shown in Figure 2, the grabbing drive device 300 includes a driving motor 231, a screw 232 and a ball nut seat (not shown in the figure). The driving motor 231 is, for example, a servo motor, and the driving motor 231 is connected to the screw 232 to drive the screw 232 to rotate, and the screw 232 cooperates with the ball nut seat. Among them, the ball nut seat is connected to the basket lifting mechanism 220. In this way, the driving motor 231 drives the screw 232 to rotate, which can drive the basket lifting mechanism 220 to rise or fall.

[0040] It is understandable that in other examples, the grabbing drive device 300 is not limited to being a motor screw transmission assembly, for example, it can also be a telescopic cylinder that can drive the basket lifting mechanism 220 to rise and fall.

[0041] The grabbing driving device 300 drives the mobile installation mechanism 210 to move along the guiding device 100, so that the mobile installation mechanisms 210 on both sides are brought closer or farther away from each other, so that the basket lifting mechanisms 220 on both sides are closed to grab the loading basket or release the loading basket.

[0042] In one example, the grabbing drive device 300 is a telescopic cylinder. Further, when the telescopic cylinder is retracted, the movable mounting mechanisms 210 on both sides are brought closer together, and the basket lifting mechanisms 220 on both sides are closed to grab the loading basket. On the contrary, when the telescopic cylinder is extended, the movable mounting mechanisms 210 on both sides are moved away from each other, and the basket lifting mechanisms 220 on both sides release the loading basket.

[0043] It is understandable that in other examples, the grabbing driving device 300 is not limited to being a telescopic cylinder, as long as it can drive the two side mobile installation mechanisms 210 to move closer or farther away. For example, the grabbing driving device 300 can also be a motor screw transmission assembly.

[0044] In one example, the grabbing driving devices 300 are respectively connected to both ends of the mobile installation mechanism 210 to make the force on the mobile installation mechanism 210 more balanced.

[0045] Optionally, the number of basket lifting mechanisms 220 connected to each mobile installation mechanism 210 is not limited to only one, and multiple basket lifting mechanisms 220 may also be connected, such as 2 to 10 basket lifting mechanisms 220 connected to each mobile installation mechanism 210. More specifically, the mobile installation mechanism 210 is a strip structure, and the multiple basket lifting mechanisms 220 are arranged along the extension direction of the mobile installation mechanism 210. In the specific example shown in the figure, four basket lifting mechanisms 220 are respectively connected to the mobile installation mechanisms 210 on both sides, and four loading baskets can be carried at the same time.

[0046] In one example, the gripping device 200 further includes a connecting member (not shown in the figure), and multiple basket lifting mechanisms 220 on the same mobile installation mechanism 210 are connected to the lifting mechanism 230 through the same connecting member. In this way, multiple basket lifting mechanisms 220 on the same mobile installation mechanism 210 can be lifted and lowered synchronously. More specifically, the connecting member is a strip-shaped structure, and the multiple basket lifting mechanisms 220 are arranged along the extension direction of the connecting member.

[0047] In one example, both ends of the connecting member are respectively connected to the lifting mechanism 230 to make the force on the connecting member more balanced.

[0048] In one example, the grabbing drive device 300 and the lifting mechanism 230 located at both ends of the mobile installation mechanism 210 are both disposed in the protective cover 500 .

[0049] As shown in FIGS. 2 to 5 , in one example, the basket lifting mechanism 220 includes a supporting component 221 and a grab hook 222 . The supporting component 221 is connected to the lifting mechanism 230 , and the grab hook 222 is connected to the supporting component 221 .

[0050] In one example, the support member 221 is a plate-shaped structure.

[0051] Optionally, the number of the grab hooks 222 on the support member 221 is not limited to only one, and multiple grab hooks 222 may be connected, such as 2 to 10. Providing multiple grab hooks 222 can improve the stability of picking up and placing the loading basket.

[0052] The grab hook 222 is connected to the support member 221 through a fastener 223, and the fastener 223 plays a role in fixing the grab hook 222. Further, an anti-slip groove 2212 is provided on the support member 221, and the fastener 223 is clamped in the anti-slip groove 2212. The shape and size of the anti-slip groove 2212 are adapted to the fastener 223 to prevent the fastener 223 from sliding.

[0053] The grab hook on the traditional robot arm is fixed by bolts. Friction between the grab hook and the basket lifting device is easy to cause the bolts to slip, causing the grab hook to loosen, resulting in abnormalities when the robot arm grabs the loading basket, and easy unhooking when placing the basket, damaging the silicon wafer. In the above example, by providing an anti-slip groove 2212 on the support component 221, the fastener 223 adopts an embedded design and is fixed in the anti-slip groove 2212 of the support component 221, which can prevent the fastener 223 from rotating, thereby preventing the grab hook 222 from loosening, and ensuring that the grab hook 222 can normally grab the loading basket.

[0054] In one example, the fastener 223 may be, but is not limited to, a nut, which is threadedly connected to the catch 222. In one example, the fastener 223 is a hexagonal nut, and accordingly, the anti-slip slot 2212 is a hexagonal slot.

[0055] The fastener 223 is preferably completely located in the anti-slip groove 2212, that is, it does not protrude from the anti-slip groove 2212. In one example, the outer side of the fastener 223 is flush with the support component 221, and does not occupy the space of the outwardly extending portion of the grab hook 222, that is, it does not occupy the effective space for the grab hook 222 to grab the flower basket, so as to avoid affecting its normal grabbing of the loading basket, and even when grabbing the loading basket, the loading basket falls into the groove body and damages the silicon wafer.

[0056] Since the nut needs to be embedded in the support member 221, the thickness of the nut is preferably not greater than the thickness of the support member 221, but it should not be too thin, otherwise the nut will easily loosen and the fixing effect will be poor. For example, if the thickness of the support member 221 is 1.5 cm, a nut with a thickness of 1 cm is selected. Compared with round nuts, the angular parts of the hexagonal nut can more effectively prevent rotation, so that the hexagonal nut can be more stable when installed on the support member 221, effectively reducing the probability of the hook 222 loosening.

[0057] As shown in FIG5 , in one example, the handling device 10 further includes a detection device 400, which is used to detect the relative position between the basket lifting mechanism 220 and the loading basket. The detection device 400 includes a guide seat 410, a lifting detection member 420, and a sensor 430. The guide seat 410 is disposed on the basket lifting mechanism 220, and the lifting detection member 420 is movably disposed on the guide seat 410. The sensor 430 is used to sense the height of the lifting detection member 420.

[0058] When the basket lifting mechanism 220 descends to grab the loading basket, the lifting detection member 420 abuts against the support rod of the loading basket, and as the height of the basket lifting mechanism 220 decreases, the lifting detection member 420 is lifted up. In a natural state, the guide seat 410 supports the lifting detection member 420 so that the lifting detection member 420 will not fall. When the lifting detection member 420 is lifted up, the guide seat 410 guides the lifting detection member 420 so that the lifting detection member 420 moves in the vertical direction. When the lifting detection member 420 rises to a certain height, it means that the basket lifting mechanism 220 has been lowered into place and can accurately grab the loading basket. At this time, the sensor 430 senses the lifting detection member 420. Under this sensing information, the lifting mechanism 230 stops driving the basket lifting mechanism 220 to descend.

[0059] In one example, the lifting detection member 420 is a rod-shaped structure.

[0060] Optionally, the sensor 430 may be, but is not limited to, a photoelectric sensor, a proximity switch, or the like.

[0061] The above-mentioned transport equipment 10 is provided with a guide device 100, and a gripping device 200 is arranged in pairs on the guide device 100. The mobile installation mechanism 210 of the gripping device 200 is slidably matched with the guide device 100. The gripping drive device 300 is used to drive the mobile installation mechanism 210 to move, so that the mobile installation mechanisms 210 on both sides are close to or away from each other, so that the basket lifting mechanisms 220 on both sides are closed to grab the loading basket or release the loading basket. The lifting mechanism 230 is used to drive the basket lifting mechanism 220 to rise or fall, so as to realize the transfer of the loading basket in the vertical direction. The above-mentioned transport equipment 10 is supported by the guide device 100 of the gripping device 200 and the basket lifting mechanism 220 as a whole, so as to improve the problem of uneven force on the gripping device when the traditional gripping device uses a lifting column for single-side support, improve the deviation of the gripping device 200, extend the service life of the gripping device 200, and improve the basket lifting effect of the gripping device 200.

[0062] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments 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.

[0063] The above-mentioned 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 scope of the utility model patent. 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. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
