[0025] Example 1

[0026] The first embodiment of the present application provides a solar cell sintering furnace, which includes:

[0027] A furnace body, which is provided with a feed inlet and a discharge outlet;

[0028] A furnace belt 10 extends from the feed port into the furnace body and extends from the discharge port. The furnace belt 10 is slidably arranged to feed the solar cell 9 into the furnace body for sintering and to feed the sintered solar cell 9 out of the furnace body.

[0029] The handling device includes a frame 1, a battery cell suction cup 8 and a suction cup translation mechanism. The frame 1 is arranged at the top of the discharge port, the suction cup translation mechanism is arranged on the frame 1, and the battery cell suction cup 8 is connected to the suction cup translation mechanism. The suction cup translation mechanism drives the battery cell suction cup 8 to move horizontally to the top of the furnace belt 10 to adsorb the sintered solar cell 9; or drives the battery cell suction cup 8 adsorbed with the sintered solar cell 9 to move horizontally to the side of the furnace belt 10.

[0030] like Figure 1 As shown, in this embodiment, the furnace body is exemplarily described as the main functional unit of the solar cell sintering furnace, which is used to sinter the solar cell 9. The feed port provided on the furnace body is used for the solar cell 9 to enter the furnace body, and the discharge port provided on the furnace body is used for the solar cell 9 to be discharged after sintering. During the sintering operation, the solar cell 9 can be arranged on the furnace belt 10, which extends into the interior of the furnace body from the feed port and extends from the discharge port. The furnace belt 10 can be rotated to continuously convey the solar cell 9. After the solar cell 9 is sintered, it can also be further conveyed to the next preparation process through the furnace belt 10.

[0031] When the solar cell 9 is being transported to the next preparation process, if the solar cell 9 is blocked during the transport process, the furnace belt 10 will stop moving, and the solar cell 9 that has been sintered will be retained in the furnace body, and further sintering will affect its quality. At the same time, because the furnace belt 10 stops moving, the solar cell 9 that has not yet been sintered cannot enter the furnace body, which affects the sintering efficiency of the solar cell 9. In this embodiment, the transport device can move the solar cell 9 that has been sintered and blocked to the side of the furnace belt 10 to avoid the solar cell 9 from getting blocked.

[0032] like Figure 1 As shown, the frame 1 can be connected to the furnace body and positioned at the top of the discharge port, and can be configured as a gantry. A suction cup translation mechanism is disposed on the frame 1 and connected to the cell suction cup 8. It is used to drive the cell suction cup 8 to move horizontally. The path along which the suction cup translation mechanism drives the cell suction cup 8 to move at least intersects with the furnace belt 10. In this embodiment, the path along which the suction cup translation mechanism drives the cell suction cup 8 to move is perpendicular to the furnace belt 10. When the suction cup translation mechanism drives the cell suction cup 8 to move above the furnace belt 10, a relatively small gap is created between the cell suction cup 8 and the solar cell 9 on the furnace belt 10, allowing the cell suction cup 8 to absorb the solar cell 9 through suction. Once the solar cell 9 is absorbed, a gap is created between the solar cell 9 and the furnace belt 10, allowing the suction cup translation mechanism to continue to drive the cell suction cup 8 to move the solar cell 9 to the side of the furnace belt 10.

[0033] It can be understood that the present application sets up a conveying device through the discharge port of the furnace body, and when the solar cell 9 is blocked, the suction cup translation mechanism of the conveying device can drive the cell suction cup 8 of the conveying device to move horizontally to the top of the furnace belt 10 to adsorb the sintered solar cell 9, and after adsorption, the solar cell 9 is moved horizontally to the side of the furnace belt 10, so that the furnace belt 10 can continue to operate to avoid the blockage of the solar cell 9; therefore, the present application can avoid the sintered solar cell 9 from being retained in the furnace body and affecting its quality, and at the same time can avoid the solar cell 9 that has not yet been sintered from being unable to enter the furnace body and affecting the sintering efficiency of the solar cell 9.

[0034] Specifically, the handling device also includes a storage box 11, which is arranged next to the furnace belt 10 and on one side of the discharge port. The suction cup translation mechanism drives the battery cell suction cup 8 to move horizontally between the storage box 11 and the furnace belt 10.

[0035] like Figure 1As shown, in this embodiment, for example, the storage box 11 can be configured as a box body with an opening at the top, and the shape of its cross section can be the same as the shape of the solar cell 9. Since the solar cell 9 is generally rectangular, the storage box 11 can be a rectangular box body. The length and width of the cross section of the storage box 11 can be slightly larger than the length and width of the solar cell 9 to facilitate the placement of the solar cell 9 into the storage box 11. The storage box 11 can be arranged side by side with the furnace belt 10, and when the cell suction cup 8 moves horizontally under the drive of the suction cup translation mechanism, it moves between the furnace belt 10 and the storage box 11; in other words, the storage box 11 is arranged on the path of horizontal movement of the cell suction cup 8.

[0036] like Figure 1 As shown, in this embodiment, after the cell suction cup 8 moves to the top of the furnace belt 10 to absorb the solar cell 9, it can continue to move to the top of the storage box 11, then cancel the absorption of the solar cell 9 and place the solar cell 9 into the storage box 11. Thereafter, the cell suction cup 8 can be moved back to the top of the furnace belt 10 to continue to absorb the blocked solar cell 9.

[0037] Of course, depending on actual needs, the cell suction cup 8 can also absorb the solar cell 9 in the storage box 11 when it moves above the storage box 11, and cancel the absorption of the solar cell 9 when it continues to move above the furnace belt 10, so as to put the solar cell 9 back onto the furnace belt 10, so that the solar cell 9 can enter the next preparation process. In some embodiments, the solar cell 9 can also be loaded into the next preparation process by other methods.

[0038] It can be understood that, by providing a storage box 11 and by reasonably setting the installation position of the storage box 11, the solar cell 9 that is blocked can be placed in the storage box 11 for temporary storage through the cell suction cup 8, so that the cell suction cup 8 can continue to adsorb the blocked solar cell 9, thereby improving the ability of the handling device to prevent the solar cell 9 from being blocked.

[0039] More specifically, the transport device further includes an adjusting mechanism, which is connected to the storage box 11 and is used to adjust the height of the solar cell 9 in the storage box 11 relative to the furnace belt 10 .

[0040] like Figure 1As shown, in this embodiment, by way of example, when the solar cell 9 is temporarily stored in the storage box 11 to a certain height, the cell suction cup 8 may interfere with the solar cell 9 in the storage box 11 and be unable to continue to move horizontally. At this time, the height of the solar cell 9 temporarily stored in the storage box 11 relative to the grate belt 10 can be adjusted by an adjustment mechanism, so that the height of the solar cell in the storage box 11 relative to the grate belt 10 is lowered, thereby allowing the cell suction cup 8 to continue to place the solar cell 9 into the storage box 11. The adjustment mechanism can be a linear module, and the storage box 11 can be integrally arranged on a slider of the linear module to move synchronously with the slider of the linear module; when the storage box 11 moves vertically downward, the height of the solar cell 9 relative to the grate belt 10 is lowered.

[0041] Of course, in some embodiments, the adjustment mechanism can also be an electric cylinder, and the bottom of the storage box 11 can be set as a movable plate and connected to the piston end of the electric cylinder to move under the drive of the electric cylinder; when the bottom of the storage box 11 moves vertically downward, the height of the solar cell 9 relative to the furnace belt 10 is reduced.

[0042] It can be understood that this embodiment provides an adjustment mechanism to adjust the height of the solar cell 9 in the storage box 11, which can increase the number of solar cell 9 that can be temporarily stored in the storage box 11, thereby further improving the ability of the transport device to prevent the solar cell 9 from being blocked.

[0043] Specifically, the suction cup translation mechanism includes a driving motor 6, a driving wheel, a driven wheel 2 and a belt 3. The driving wheel and the driven wheel 2 are rotatable, the belt 3 is arranged between the driving wheel and the driven wheel 2, the driving motor 6 is transmitted to the driving wheel, and the battery cell suction cup 8 is arranged on one side of the belt 3 through the support frame 5.

[0044] like Figure 1As shown, in this embodiment, for illustrative purposes, the driving pulley and driven pulley 2 can be mounted on the frame 1 and rotatably arranged. The belt 3 wraps around the driving pulley and driven pulley 2 and is disposed between them. The tension of the belt 3 can be adjusted appropriately based on actual needs, specifically by adjusting the length of the belt 3. The drive motor 6 can be a stepper motor and mounted on the frame 1. The output of the drive motor 6 can be connected to the driving pulley via a coupling or other components. When the output of the drive motor 6 drives the driving pulley to rotate, the driving pulley can drive the driven pulley 2 to rotate via the belt 3, and the belt 3 can also rotate. The cell suction cup 8 can be mounted on the support frame 5, which can be mounted on one side of the belt 3. When the belt 3 rotates, it can drive the support frame 5 to translate, thereby achieving horizontal movement of the cell suction cup 8. By setting the forward and reverse rotation directions of the drive motor 6, horizontal movement of the cell suction cup 8 between the storage box 11 and the furnace belt 10 can be achieved.

[0045] It can be understood that this embodiment can achieve horizontal movement of the battery cell suction cup 8 by reasonably setting the component structure and connection relationship of the suction cup translation mechanism, and at the same time ensure the stability of the battery cell suction cup 8 during the movement.

[0046] More specifically, the frame 1 is further provided with a slide rail 4 , and the support frame 5 is slidably provided on the slide rail 4 .

[0047] like Figure 1 As shown, in this embodiment, for example, the slide rail 4 can be disposed below the belt 3 and on the frame 1; the length direction of the slide rail 4 is the same as the direction of movement of the support frame 5. When the support frame 5 is disposed on the furnace belt 10, the support frame 5 is also slidably connected to the slide rail 4. When the furnace belt 10 drives the support frame 5 to move synchronously, the support frame 5 can be guided by the slide rail 4 to further improve its smoothness during movement. When the support frame 5 moves more smoothly, the vibration to the cell suction cup 8 and the solar cell 9 adsorbed thereon can be reduced during movement.

[0048] More specifically, a fixing plate is provided on the support frame 5 , and the battery cell suction cup 8 is provided on the fixing plate. The fixing plate is provided with a waist-shaped hole, and the battery cell suction cup 8 is adjustably provided in the waist-shaped hole.

[0049] like Figure 1As shown, in this embodiment, for example, the support frame 5 can be set vertically to be close to the furnace belt 10; the fixing plate can be set horizontally and set at the bottom of the support frame 5. The fixing plate can be set to a rectangle, the waist-shaped hole can be set in the middle position of the fixing plate, and the length direction of the waist-shaped hole can be set according to actual needs, for example, it can be the length direction of the furnace belt 10. The battery cell suction cup 8 can be adjustably set in the waist-shaped hole by components such as bolts and nuts. For example, a bolt is provided on the battery cell suction cup 8, and the bolt passes through the waist-shaped hole and is locked and fixed to the fixing plate by a nut. When the position of the battery cell suction cup 8 needs to be adjusted, the lock nut is loosened, and the bolt is driven to slide to the specified position in the waist-shaped hole, and then the nut is re-tightened.

[0050] It can be understood that this embodiment can adjust the position of the battery cell suction cup 8 in the waist-shaped hole by adjustably setting the battery cell suction cup 8 in the waist-shaped hole, so that the battery cell suction cup 8 can better adsorb the solar cell 9, avoiding the solar cell 9 from falling due to uneven force.

[0051] Specifically, the solar cell sintering furnace further includes a sensor 7 , which is arranged beside the furnace belt 10 through a fixed bracket and is arranged on one side of the discharge port.

[0052] like Figure 1 As shown, in this embodiment, it is exemplified that the sensor 7 can be used to detect whether the solar cell 9 is blocked on the furnace belt 10. For example, the sensor 7 is a laser sensor 7, which can indirectly determine whether the solar cell 9 is blocked on the furnace belt 10 by detecting whether there is a solar cell 9 at its current detection position. The sensor 7 can be set on a fixed bracket and on one side of the discharge port. The fixed bracket can be set as a rod-shaped structure and can be set as an inverted "L" shape. The top of the fixed bracket can extend in a direction close to the furnace belt 10, and the sensor 7 can be set on the top of the fixed bracket and close to the furnace belt 10. The sensor 7 can be electrically connected to the controller, and the drive motor 6 can be controlled by the controller. When the sensor 7 detects that the solar cell 9 is blocked on the furnace belt 10,

[0053] It can be understood that in this embodiment, the sensor 7 is set next to the furnace belt 10 through a fixed bracket, and the sensor 7 can be used to detect whether the solar cell 9 is blocked on the furnace belt 10, so that when it is blocked, the conveying device is automatically activated to adsorb the solar cell 9 into the storage box 11 for temporary storage.

[0054] Specifically, there are two groups of feed ports and discharge ports, two furnace belts 10 are provided, and they correspond one-to-one to the two groups of feed ports and discharge ports, there are two groups of battery cell suction cups 8 and suction cup translation mechanisms, and they correspond one-to-one to the two furnace belts 10, and both groups of suction cup translation mechanisms are provided on the frame 1.

[0055] like Figure 1 As shown, in this embodiment, the furnace body can sinter two groups of solar cells 9 at the same time. Each group of solar cells 9 can be fed into the furnace body through a corresponding furnace belt 10. The two furnace belts 10 can be arranged side by side and in parallel. Correspondingly, two groups of inlets and outlets are also provided on the furnace body to facilitate the passage of the two furnace belts 10 through the furnace body. Similarly, two groups of cell suction cups 8 and suction cup translation mechanisms can be provided to correspond to the two furnace belts 10. The two groups of cell suction cups 8 and suction cup translation mechanisms are independently controlled to respectively absorb the solar cells 9 that are blocked on the two furnace belts 10. Only one frame 1 can be provided, and the two groups of suction cup translation mechanisms can be provided on the same frame 1.

[0056] It is understandable that this embodiment, by providing two furnace belts 10, two sets of cell suction cups 8 and a suction cup translation mechanism, can improve the sintering efficiency of the furnace body while preventing the solar cell 9 from being blocked in any of the two furnace belts 10.

[0057] The implementation principle of a solar cell sintering furnace provided in Example 1 of the present application is as follows:

[0058] During sintering, the furnace belt 10 translates to feed solar cells 9 into the furnace from the feed port for sintering. The cells are then discharged from the furnace through the discharge port, allowing the cells 9 to flow to the next production process. If a blockage occurs during the transfer of the cells 9 to the next production process, the sensor 7 detects the blockage. The output of the drive motor 6 then drives the driving pulley to rotate, which in turn drives the driven pulley 2 via the belt 3. The belt 3 then rotates, driving the support frame 5 to translate. This translation of the support frame 5 drives the cell suction cup 8 to move horizontally. When the cell suction cup 8 moves above the furnace belt 10, it absorbs the solar cell 9 on the furnace belt 10, separating the solar cell 9 from the furnace belt 10. The output of the drive motor 6 then reverses, driving the cell suction cup 8 to move above the storage box 11. The suction cup 8 then releases its grip on the solar cell 9, allowing the solar cell 9 to be placed into the storage box 11. When the support frame 5 moves horizontally, the slide rail 4 guides it, so that the movement of the cell suction cup 8 is more stable. When the solar cells 9 in the storage box 11 are stacked to a certain height, the adjustment mechanism adjusts the height of the solar cells 9 temporarily stored in the storage box 11 relative to the grate belt 10, so that the height of the solar cells in the storage box 11 relative to the grate belt 10 is lowered, thereby allowing the cell suction cup 8 to continue to drop the solar cells 9 into the storage box 11.

[0059] The present application sets a conveying device at the discharge port of the furnace body. When the solar cell 9 is blocked, the suction cup translation mechanism of the conveying device drives the cell suction cup 8 of the conveying device to move horizontally to the top of the furnace belt 10 to adsorb the sintered solar cell 9, and after adsorption, the solar cell 9 is moved horizontally to the side of the furnace belt 10, so that the furnace belt 10 can continue to operate to avoid the blockage of the solar cell 9; therefore, the present application can avoid the sintered solar cell 9 from being retained in the furnace body and affecting its quality, and at the same time can avoid the solar cell 9 that has not yet been sintered from being unable to enter the furnace body and affecting the sintering efficiency of the solar cell 9.

[0060] Example 2

[0061] A second embodiment of the present application provides a solar cell sintering furnace. The difference between this embodiment and the first embodiment lies at least in the composition structure of the transport device.

[0062] Specifically, the handling device also includes a suction cup lifting mechanism 12, which is connected to the battery cell suction cup 8. The suction cup lifting mechanism 12 drives the battery cell suction cup 8 to move vertically. The suction cup translation mechanism is connected to the suction cup lifting mechanism 12. The suction cup translation mechanism drives the suction cup lifting mechanism 12 and the battery cell suction cup 8 to move horizontally.

[0063] like Figure 2 As shown, in this embodiment, for example, the handling device further includes a suction cup lifting mechanism 12. The suction cup lifting mechanism 12 can be a linear module. The cell suction cup 8 can be connected to the slider of the suction cup lifting mechanism 12 so that it can move vertically under the drive of the slider of the suction cup lifting mechanism 12 to achieve the lifting and lowering of the cell suction cup 8. At the same time, the guide rail of the suction cup lifting mechanism 12 can be connected to the belt 3 of the suction cup translation mechanism so that it can move horizontally under the drive of the belt 3 of the suction cup translation mechanism to indirectly achieve the translation of the cell suction cup 8. When it is necessary to adsorb the solar cell 9, the cell suction cup 8 can first be raised by the suction cup lifting mechanism 12, then translated to directly above the furnace belt 10, and then driven by the suction cup lifting mechanism 12 to descend until it contacts the solar cell 9 and then adsorbs it.

[0064] In this embodiment, similarly, when the solar cell 9 needs to be placed into the storage box 11, the solar cell 9 can be first raised by the suction cup lifting mechanism 12 so that the translation of the solar cell 9 is not easily obstructed. Then, when it moves to the top of the storage box 11, the solar cell 9 is lowered by the suction cup lifting mechanism 12 to smoothly place the solar cell 9 into the storage box 11.

[0065] It can be understood that, in this embodiment, by providing a suction cup lifting device, the degree of freedom of movement of the cell suction cup 8 is further improved, so that the cell suction cup 8 can smoothly adsorb the solar cell 9.

[0066] Example 3

[0067] The third embodiment of the present application provides a transport device that also includes a suction cup lifting mechanism 12. The difference between this embodiment and the second embodiment lies at least in the connection relationship between the various components of the transport device.

[0068] Specifically, the suction cup lifting mechanism 12 is connected to the suction cup translation mechanism, and the suction cup lifting mechanism 12 drives the suction cup translation mechanism and the battery cell suction cup 8 provided on the suction cup translation mechanism to move vertically.

[0069] In this embodiment, for example, the suction cup lifting mechanism 12 can also be a linear module, but the slider of the suction cup lifting mechanism 12 is connected to the suction cup translation mechanism. For example, the guide rail of the suction cup lifting mechanism 12 is mounted on the frame, and the suction cup translation mechanism is mounted on a fixed plate, which is connected to the slider of the suction cup lifting mechanism 12. The cell suction cup 8 is still connected to the belt 3 of the suction cup translation mechanism via the support frame 5. When the solar cell 9 needs to be sucked, the suction cup lifting mechanism 12 can drive the suction cup translation mechanism and the cell suction cup 8 mounted on the suction cup translation mechanism to rise synchronously. The suction cup translation mechanism then drives the cell suction cup 8 to translate directly above the furnace belt 10. The suction cup lifting mechanism 12 then drives the suction cup translation mechanism and the cell suction cup 8 mounted on the suction cup translation mechanism to descend synchronously until the cell suction cup 8 contacts the solar cell 9 and then sucks it. When the solar cell 9 needs to be placed into the storage box 11, the same principle can be applied.

[0070] It is understandable that this embodiment can also further improve the freedom of movement of the cell suction cup 8 so that the cell suction cup 8 can smoothly adsorb the solar cell 9 .

[0071] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above 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.

[0072] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art could make various modifications and improvements without departing from the spirit of the present application, all of which fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
