[0052] The present application provides a sheet material receiving device, which can automatically transfer a material box full of sheets on a material box carrying mechanism to a material box conveying device, and automatically replenish an empty material box output by the material box conveying device to an emptied material box carrying mechanism, thereby improving the sheet material receiving efficiency and reducing the material receiving cost.

[0053] The sheets collected by the sheet collecting device of the present application may be silicon sheets or battery sheets in the production process of photovoltaic modules, or may be other sheet products.

[0054] The structure and working process of the sheet receiving device of the present application will be described exemplarily through two embodiments below.

[0055] First embodiment

[0056] like Figure 1 to Figure 2 As shown, the sheet receiving device in this embodiment includes a sheet conveying line 1, a material box transfer mechanism 2, a plurality of sheet taking mechanisms 3, a plurality of material box carrying mechanisms 4 and a material box conveying device, wherein:

[0057] The sheet conveyor line 1 is configured to convey sheets, and the conveying path of the sheet conveyor line 1 (such as Figure 1 A plurality of film taking stations are arranged in the X-axis direction in the image processing apparatus, each of which is provided with a film taking mechanism 3, and a material box carrying mechanism 4 for carrying a material box is arranged on the side of each film taking station.

[0058] Figure 1 In the sheet receiving device shown in the figure, a total of 9 sheet picking stations are arranged on the conveying path of the sheet conveying line 1, and correspondingly, 9 sheet picking mechanisms 3 are arranged above the sheet conveying line 1, and 9 material box carrying mechanisms 4 are arranged on the side of the sheet conveying line 1. Of course, the number of sheet picking stations, sheet picking mechanisms 3 and material box carrying mechanisms 4 can be adjusted according to actual needs.

[0059] The film taking mechanism 3 includes a film taking conveying part 31 and a film placing conveying part 32, wherein the film taking conveying part 31 is located above the corresponding film taking station, and the output end of the film placing conveying part 32 is opposite to the material box, wherein: the film taking conveying part 31 is configured to absorb the film body located at the film taking station and convey the film body to the film placing conveying part 32. The film placing conveying part 32 is used to receive the film body output by the film taking conveying part 31, and convey the film body to the material box 100 located on the material box bearing mechanism 4. Optionally, the film taking conveying part 31 and the film placing conveying part 32 both include a mounting bracket and a conveying belt and an adsorption component arranged at the bottom of the mounting bracket, wherein the adsorption component is used to adsorb the film body on the conveying belt, and the conveying belt is used to convey the film body.

[0060] The material box transfer mechanism 2 includes a first translation driving module 21, a first material box transfer part 22 and a second material box transfer part 23, wherein: the first translation driving module 21 is arranged parallel to the conveying path of the sheet conveying line 1. The first material box transfer part 22 and the second material box transfer part 23 are connected side by side on the driving end of the first translation driving module 21, and the first translation driving module 21 is configured to drive the first material box transfer part 22 and the second material box transfer part 23 to reciprocate and translate in parallel to the conveying path of the sheet conveying line, so as to drive the first material box transfer part 22 and the second material box transfer part 23 to pick up the material box full of sheets from the material box carrying mechanism 4, and transfer the material box full of sheets to the material box conveying device, and receive the empty material box from the material box conveying device, and put the empty material box back to the empty material box carrying mechanism 4.

[0061] The first translation driving module 21 can adopt various existing linear driving modules that can drive the first material box transfer part 22 and the second material box transfer part 23 to reciprocate and translate.

[0062] By providing the material box transfer mechanism 2, the sheet receiving device in this embodiment can automatically transfer the material box full of sheets on the material box carrying mechanism 4 to the material box conveying device, and automatically replenish the empty material box output by the material box conveying device to the empty material box carrying mechanism 4, thereby improving the sheet receiving efficiency and reducing the receiving cost. In particular, the material box transfer mechanism 2 is provided with two material box transfer parts, and the two material box transfer parts can implement material box transfer in parallel, thereby further improving the sheet receiving efficiency.

[0063] Optionally, the first translation driving module 21 has two independent driving ends, the first material box transporting part 22 is connected to the first driving end, and the second material box transporting part 23 is connected to the second driving end. The first translation driving module 21 independently drives the first material box transporting part 22 to translate through the first driving end, and independently drives the second material box transporting part 23 to translate through the second driving end. In this way, the first material box transporting part 22 and the second material box transporting part 23 each independently implement material box transport, thereby improving the flexibility of the material box transporting mechanism 2.

[0064] Of course, the first material box transfer part 22 and the second material box transfer part 23 can also be connected to the same driving end of the first translation driving module 21, and the first translation driving module 21 drives the first material box transfer part 22 and the second material box transfer part 23 to translate synchronously to implement material box transfer. Such a configuration can reduce the cost of the material box transfer mechanism and avoid the first material box transfer part 22 and the second material box transfer part 23 from touching each other.

[0065] like Figure 3 As shown, optionally, the material box carrying mechanism 4 in this embodiment includes a lifting and adjusting part 41 and a carrying plate 42, wherein the carrying plate 42 is connected to the driving end of the lifting and adjusting part 41, the carrying plate 42 is used to carry the material box, and the lifting and adjusting part 41 is used to drive the carrying plate to rise and fall. The lifting and adjusting part 41 is used to adjust the height of the carrying plate 42 to ensure that the carrying plate 42 can be docked with the first material box transport part 22 and the second material box transport part 23, so that the first material box transport part 22 and the second material box transport part 23 can smoothly pick up the material box full of sheets from the carrying plate 42, and put the empty material box back on the carrying plate 42.

[0066] Optionally, at least one first sensor and at least one second sensor are installed on the carrier plate 42, wherein the first sensor is arranged corresponding to the first side edge (such as the left side edge) of the silicon wafers in the material box on the carrier plate 42, and the first sensor is configured to detect whether the first side edges of the silicon wafers stacked in the material box are aligned. The second sensor is arranged corresponding to the second side edge (such as the right side edge) of the silicon wafers in the material box on the carrier plate 42, and the second sensor is configured to detect whether the second side edges of the silicon wafers stacked in the material box are aligned, and the first side edge and the second side edge are adjacent side edges of the silicon wafers. When the sheet-taking mechanism 3 collects the sheet body into the material box, the first sensor and the second sensor detect in real time whether the silicon wafers stacked in the material box are aligned. If it is found that the silicon wafers in the material box are not aligned, the material box with the unaligned silicon wafers on the carrier plate 42 can be removed manually or by other manipulators, or the material box with the unaligned silicon wafers can be removed first, and the corresponding processing can be performed after the subsequent material box conveying device is removed.

[0067] The second material box transfer part 23 in this embodiment has the same structure as the first material box transfer part 22. Figure 4 As shown, taking the first material box transport unit 22 as an example, it includes a second translation drive module 221, a lifting drive module 222 and a pick-up assembly 223, wherein: the second translation drive module 221 is connected to the driving end of the first translation drive module 21, the lifting drive module 222 is connected to the driving end of the second translation drive module 221, and the pick-up assembly 223 is connected to the driving end of the lifting drive module 222. The second translation drive module 222 is configured to drive the pick-up assembly 223 to move perpendicularly to the conveying path of the sheet conveying line 1 (such as Figure 4 The lifting drive module 222 is configured to drive the picking component 223 to lift and lower, so that the picking component 223 is docked with the material box carrying mechanism 4, or docked with the material box conveying device.

[0068] When the picking component 223 is docked with the magazine carrier 4, the picking component 223 picks up a magazine full of sheets from the magazine carrier 4, or puts an empty magazine back onto the magazine carrier 4. When the picking component 223 is docked with the magazine conveying device, the picking component 223 places a magazine full of sheets onto the magazine conveying device, or receives an empty magazine outputted by the magazine conveying device.

[0069] It can be seen that through the coordinated driving of the second translation drive module 221 and the lifting drive module 222, the docking of the picking component 223 and the material box supporting mechanism 4 or the material box conveying device can be realized, ensuring that the picking component 223 can smoothly pick up the material box full of sheets from the material box supporting mechanism 4 or put the empty material box back onto the material box supporting mechanism 4, and place the material box full of sheets on the material box conveying device or receive the empty material box output by the material box conveying device.

[0070] Still taking the first material box transfer unit 22 as an example, when the first material box transfer unit 22 needs to pick up a material box full of sheets from the material box supporting mechanism 4 or needs to transfer an empty material box to the material box supporting mechanism 4, the position of the picking component 223 can be adjusted by the second translation drive module 221 and the lifting drive module 222, so that the picking component 223 is aligned with the material box supporting mechanism 4, and then the first translation drive module 21 drives the first material box transfer unit 22 to translate toward the material box supporting mechanism 4 into place, so that the picking component 223 can be accurately connected with the material box supporting mechanism 4.

[0071] When the first material box transfer unit 22 needs to transfer a material box full of sheets to a material box conveying device or needs to pick up an empty material box from the material box conveying device, the position of the picking component 223 can be adjusted by the second translation drive module 221 and the lifting drive module 222, so that the picking component 223 is aligned with the material box conveying device, and then the first translation drive module 21 drives the first material box transfer unit 22 to translate toward the material box conveying device into place, so that the picking component 223 can be accurately connected with the material box conveying device.

[0072] Continue to refer Figure 4 As shown, optionally, the picking assembly 223 includes two hook plates 2231 arranged opposite to each other, and a hook claw 2232 for hooking the material box is arranged at the bottom of the hook plate 2231.

[0073] Still taking the first material box transporting part 22 as an example, when it is necessary to pick up a material box full of sheets from the material box carrying mechanism 4, the first translation driving module 21 drives the first material box transporting part 22 to move toward the material box carrying mechanism 4, so that the two hook plates 2231 of the first material box transporting part 22 move to the two sides of the material box. Then the lifting driving module 222 drives the picking assembly 223 to rise, and the two hook plates 2231 hook the clamping columns on both sides of the material box through the hook claws 2232 at the bottom to lift the material box out of the carrying plate 42.

[0074] When it is necessary to transfer the material box full of sheets to the material box conveying device, the first translation drive module 21 first drives the first material box transfer part 22 carrying the material box full of sheets to move above the material box conveying device, and then the lifting drive module 222 drives the picking component 223 to descend, and the picking component 223 releases the material box to the material box conveying device.

[0075] Optionally, the material box conveying device includes a full material box conveying line and an empty material box conveying line arranged side by side, wherein the full material box conveying line is used to receive the material boxes full of sheets transferred by the first material box transfer part 22 and the second material box transfer part 23, and convey the material boxes full of sheets to the subsequent processing station. The empty material box conveying line is used to convey the empty material boxes toward the first material box transfer part 22 and the second material box transfer part 23. The first material box transfer part 22 and the second material box transfer part 23 can be alternately connected with the full material box conveying line and the empty material box conveying line to convey the material boxes full of sheets to the full material box conveying line, and receive the empty material boxes from the empty material box conveying line.

[0076] In order to improve the efficiency of material box transfer, optionally, the picking component 223 of one of the first material box transfer part 22 and the second material box transfer part 23 is docked with the full material box conveyor line. When the material box full of sheets is placed on the full material box conveyor line, the picking component 223 of the other one of the first material box transfer part 22 and the second material box transfer part 23 is docked with the empty material box conveyor line to receive the empty material box output by the empty material box conveyor line.

[0077] Optionally, the material box conveying device can also be an AGV trolley, on which a full material box conveying channel and an empty material box conveying channel are arranged side by side. The full material box conveying channel is used to receive the material box full of sheets transferred by the first material box transfer unit 22 or the second material box transfer unit 23, and the empty material box conveying channel is used to transfer the empty material box toward the first material box transfer unit 22 or the second material box transfer unit 23.

[0078] When the AGV moves to the box changing station near the material box transfer mechanism 2, the first material box transfer part 22 and the second material box transfer part 23 can alternately connect with the full material box conveying channel and the empty material box conveying channel to convey the material box full of sheets to the full material box conveying channel, and receive the empty material box from the empty material box conveying channel.

[0079] Similarly, in order to improve the efficiency of material box transfer, optionally, the picking component 223 of one of the first material box transfer part 22 and the second material box transfer part 23 is docked with the full material box conveying channel of the AGV cart. When the material box full of sheets is placed in the full material box conveying channel, the picking component 223 of the other one of the first material box transfer part 22 and the second material box transfer part 23 is docked with the empty material box conveying channel of the AGV cart to receive the empty material box output by the empty material box conveying channel.

[0080] Second embodiment

[0081] The structure and working process of the sheet collecting device in this embodiment are basically the same as those of the sheet collecting device in the first embodiment. For the sake of brevity, the following only specifically describes the differences between the sheet collecting device in this embodiment and the sheet collecting device in the first embodiment. For the rest of the same parts, please refer to the relevant description in the first embodiment.

[0082] The main difference between the sheet receiving device in this embodiment and the sheet receiving device in the first embodiment is reflected in the material box transfer mechanism 2.

[0083] like Figures 5 to 7 As shown, in this embodiment, the first material box transport unit 22 has the same structure as the second material box transport unit 23. Taking the first material box transport unit 22 as an example, it includes a third translation drive module 224 and a telescopic conveyor line 225, wherein: the third translation drive module 224 is connected to the driving end of the first translation drive module 21, and the telescopic conveyor line 225 is arranged on the third translation drive module 224. The conveying direction of the telescopic conveyor line 225 (such as Figure 6 to Figure 7 The Y-axis direction in the figure is perpendicular to the conveying path of the sheet conveying line.

[0084] The third translation driving module 224 is configured to drive the telescopic conveying line 225 to extend and retract perpendicular to the conveying path of the sheet conveying line, so that the telescopic conveying line 225 docks with the material box carrying mechanism 4 or docks with the material box conveying device.

[0085] When the telescopic conveyor line 225 is docked with the magazine carrier 4, it receives the magazine full of sheets on the magazine carrier 4, or conveys the empty magazine to the magazine carrier 4. When the telescopic conveyor line 225 is docked with the magazine conveying device, it conveys the magazine full of sheets to the magazine conveying device, and receives the empty magazine output by the magazine conveying device.

[0086] It can be seen that by driving the telescopic conveyor line 225 to extend and retract perpendicular to the conveying path of the sheet conveyor line through the third translation drive module 224, the telescopic conveyor line 225 is connected to the material box supporting mechanism 4 or the material box conveying device, so that the telescopic conveyor line 225 can pick up a material box full of sheets from the material box supporting mechanism 4 or convey an empty material box to the material box supporting mechanism 4, and convey a material box full of sheets to the material box conveying device or receive an empty material box output by the material box conveying device.

[0087] Taking the first material box transfer unit 22 as an example, when the first material box transfer unit 22 needs to pick up a material box full of sheets from the material box supporting mechanism 4 or needs to transport an empty material box to the material box supporting mechanism 4, the first translation drive module 21 first drives the first material box transfer unit 22 to move toward the material box supporting mechanism 4 to position it, so that the telescopic conveyor line 225 is aligned with the material box supporting mechanism 4, and then the third translation drive module 24 drives the telescopic conveyor line to extend toward the material box supporting mechanism 4, so that the telescopic conveyor line 225 can be connected to the material box supporting mechanism 4.

[0088] When the first material box transfer part 22 needs to transport the material box full of sheets to the material box conveying device or needs to receive the empty material box output by the material box conveying device, the first translation drive module first drives the first material box transfer part 22 to move toward the material box conveying device to position the telescopic conveyor line 225 so that the telescopic conveyor line 225 is aligned with the material box conveying device, and then the third translation drive module 224 drives the telescopic conveyor line 225 to extend toward the material box conveying device, so that the telescopic conveyor line 225 can be docked with the material box conveying device.

[0089] Optionally, the telescopic conveyor line 225 includes a first telescopic conveyor belt 2251 and a second telescopic conveyor belt 2252 arranged in parallel. When the telescopic conveyor line 225 is docked with the material box carrying mechanism 4, the telescopic conveyor line 225 is controlled to extend so that the ends of the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252 extend to both sides of the carrying plate 42 of the material box carrying mechanism 4. Subsequently, the lifting and adjusting part 41 of the material box carrying mechanism 4 drives the carrying plate 42 to descend, so that the material box filled with sheets on the carrying plate 42 can fall onto the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252, or the lifting and adjusting part 41 of the material box carrying mechanism 4 drives the carrying plate 42 to rise, so that the carrying plate 42 lifts the empty material box carried on the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252 out of the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252.

[0090] like Figure 7 and Figure 8As shown, optionally, the material box supporting mechanism 4 in this embodiment, its supporting plate 42 is a T-shaped flat plate structure, which includes a penetration portion 421 and a limiting portion 422, wherein: the width of the penetration portion 421 is smaller than the spacing between the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252, and the width of the limiting portion 422 is larger than the width of the penetration portion 421. When the telescopic conveyor line 225 is docked with the material box carrying mechanism 4, the insertion portion 421 horizontally penetrates between the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252, and the limiting portion 422 is located at the end of the first telescopic conveyor belt 2251 and the second telescopic conveyor belt 2252. At least two limiting columns 423 are vertically installed on the upper plate surface of the limiting portion 422. All limiting columns 423 are arranged at intervals in a direction parallel to the width direction of the telescopic conveyor line 225. When the telescopic conveyor line 225 transfers the empty material box to the material box carrying mechanism 4, the limiting column 423 stops the empty material box to prevent the empty material box from rushing out of the telescopic conveyor line 225, thereby ensuring that the empty material box can be accurately transferred to the material box carrying mechanism 4.

[0091] Similar to the first embodiment, the material box conveying device in this embodiment may include a full material box conveying line and an empty material box conveying line arranged side by side, wherein the full material box conveying line is used to receive the material box full of sheets transferred by the first material box transfer part 22 and the second material box transfer part 23, and convey the material box full of sheets to the subsequent processing station. The empty material box conveying line is used to convey the empty material box toward the first material box transfer part 22 and the second material box transfer part 23. The first material box transfer part 22 and the second material box transfer part 23 can alternately implement docking with the full material box conveying line and the empty material box conveying line to convey the material box full of sheets to the full material box conveying line, and receive the empty material box from the empty material box conveying line.

[0092] In order to improve the efficiency of material box transfer, optionally, the telescopic conveyor line 225 of one of the first material box transfer part 22 and the second material box transfer part 23 is connected to the full material box conveyor line. When the material box full of sheets is conveyed to the full material box conveyor line, the telescopic conveyor line 225 of the other one of the first material box transfer part 22 and the second material box transfer part 23 is connected to the empty material box conveyor line to receive the empty material box output by the empty material box conveyor line.

[0093] The material box conveying device in this embodiment can also be an AGV trolley, and a full material box conveying channel and an empty material box conveying channel are arranged side by side on the AGV trolley. Among them, the full material box conveying channel is used to receive the material box full of sheets transferred by the first material box transfer part 22 and the second material box transfer part 23, and the empty material box conveying channel is used to convey the empty material box toward the first material box transfer part 22 and the second material box transfer part 23. When the AGV trolley walks to the box changing station close to the material box transfer mechanism 2, the first material box transfer part 22 and the second material box transfer part 23 can alternately implement docking with the full material box conveying channel and the empty material box conveying channel to convey the material box full of sheets to the full material box conveying channel, and receive the empty material box from the empty material box conveying channel.

[0094] Similarly, in order to improve the efficiency of material box transfer, optionally, the telescopic conveyor line 225 of one of the first material box transfer part 22 and the second material box transfer part 23 is connected to the full material box conveying channel of the AGV cart. When the material box full of sheets is conveyed to the full material box conveying line, the telescopic conveyor line 225 of the other one of the first material box transfer part 22 and the second material box transfer part 23 is connected to the empty material box conveying channel of the AGV cart to receive the empty material box output by the empty material box conveying channel.
