Description
Technical Field
[0001] The present disclosure relates to the technical field of photovoltaic or semiconductor processing, and particularly to a buffer device and a sheet processing apparatus. Background Art
[0002] Currently, in the production process of solar cells, a laser scribing method is used to divide a silicon wafer into two halves. The cross-section is the cross-section of an unpassivated silicon wafer. The recombination at the edge of the silicon wafer cross-section increases, and the conversion efficiency will decrease by 0.2 - 0.3%. For heterojunction solar cells, due to their higher open-circuit voltage, the efficiency decreases even more after laser scribing. The reduction in the efficiency of solar cells caused by the above-mentioned cutting will directly lead to a reduction in the power of the modules made of the sliced silicon wafers. Therefore, it is necessary to passivate and coat the cut part. Passivation coating refers to forming a passivation film on the surface of the silicon wafer by deposition, so as to reduce minority carrier recombination, provide a field passivation effect, and reduce the reflectivity.
[0003] The above cross-section passivation process needs to transport the sliced silicon wafers to the passivation equipment through a drawer-type cassette. After placing the silicon wafers in the drawer-type cassette, it is necessary to place a cover plate on the silicon wafers.

Detailed implementation manners
[0028] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present disclosure without creative efforts shall fall within the protection scope of the present disclosure.
[0029] As Figures 1 to 5 shown, the buffer device 10 of this embodiment is used to store the cover plate 700, and includes a frame 11, a buffer guiding mechanism 100, a cover plate supporting plate 200, and a lifting driving mechanism 300. The frame 11 is fixed in position and used for support. The buffer guiding mechanism 100 is fixedly connected to the frame 11. The inner side of the buffer guiding mechanism 100 has a cover plate buffer channel 160, and the cover plate buffer channel 160 is configured to store a plurality of cover plates 700. A cover plate inlet and outlet is formed on the upper side of the cover plate buffer channel 160. The cover plate supporting plate 200 is slidably connected to the frame 11 and is located in the cover plate buffer channel 160, and is configured to support a plurality of cover plates 700. The lifting driving mechanism 300 is connected to the cover plate supporting plate 200, and the lifting driving mechanism 300 is configured to drive the cover plate supporting plate 200 to lift.
[0030] The cover plate buffer channel 160 of the buffer guiding mechanism 100 serves as a space for storing and lifting the cover plate 700. During use, a plurality of cover plates 700 can be stacked and stored in the cover plate buffer channel 160 or the cover plates 700 stored in the cover plate buffer channel 160 can be taken out by a handling device 20 such as a six-axis robot. When the cover plate 700 is located in the cover plate buffer channel 160, the edge position of the cover plate 700 is limited by the buffer guiding mechanism 100 to prevent the cover plate 700 from laterally shifting. Moreover, the cover plate 700 at the bottom of the plurality of cover plates 700 overlaps on the upper side of the cover plate 700 tray, so that the plurality of cover plates 700 are supported by the cover plate supporting plate 200.
[0031] The lifting driving mechanism 300 driving the cover plate 700 tray to lift can realize the storage or extraction of the cover plate 700. Specifically, when the lifting driving mechanism 300 drives the cover plate 700 tray to descend, the distance between the cover plate supporting plate 200 and the cover plate inlet and outlet gradually increases, and the cover plates 700 can be stored one by one from the cover plate inlet and outlet position. When the lifting driving mechanism 300 drives the cover plate 700 tray to ascend, the distance between the cover plate 700 tray and the cover plate inlet and outlet gradually decreases, and the stacked plurality of cover plates 700 are moved to the cover plate inlet and outlet position one by one, facilitating the handling device 20 to take out the cover plate 700.
[0032] The buffer device 10 of this embodiment can achieve the storage and continuous supply of the cover plate 700. Exemplarily, in the cross-section passivation process, the sheet group needs to be transported to the passivation equipment through a drawer-type cassette. When the sheet group is placed in the drawer-type cassette, it is necessary to place the cover plate 700 on the battery cell group through the handling device 20. Therefore, a device that can store and continuously supply the cover plate 700 is required, and the buffer device 10 of this embodiment can meet this demand, enabling the handling device to grasp the cover plate 700 and place it on the sheet group in the drawer-type cassette.
[0033] The sheet can be a silicon wafer, a glass substrate, a wafer, a battery cell, etc.
[0034] The core function of the buffer device 10 of this embodiment is to achieve the storage and continuous supply of the cover plate 700 to meet the requirements of a specific production process. Exemplarily, during the cross-section passivation process, the sheet group needs to be transported into the passivation equipment by means of a drawer-type cassette. To protect the sheet group, when placed in the drawer-type cassette, the cover plate 700 needs to be covered above the sheet group. This process requires a device that can store and continuously supply the cover plate 700 for the handling device 20 to pick up and accurately place on the sheet group. The buffer device 10 in this embodiment can stably store multiple cover plates 700 and ensure that the cover plates 700 can be continuously and smoothly grasped by the handling device and then placed on the top of the sheet group in the drawer-type cassette, which not only improves the production efficiency but also ensures the continuity of the process operation and is a key link in improving the automation and intelligence level of the overall production process.
[0035] In some embodiments of the present disclosure, the buffer guiding mechanism 100 includes a fixed seat 110 and a plurality of guiding members 120. The fixed seat 110 is fixedly connected to the frame 11, and the plurality of guiding members 120 extend in the vertical direction and are respectively arranged on the upper side of the fixed seat 110. The plurality of guiding members 120 and the fixed seat 110 enclose a cover plate buffer channel 160.
[0036] In an alternative form, the number of fixed seats 110 is two, and the two fixed seats 110 are respectively fixedly connected to the frame 11, and the two fixed seats 110 are spaced apart. The plurality of guiding members 120 are respectively arranged on the upper sides of the two fixed seats 110 and are respectively fixedly connected to the corresponding fixed seats 110. The plurality of guiding rods are supported and fixed by the fixed seats 110. Among them, the area between the plurality of guiding members 120 and the area between a pair of fixed seats 110 constitute the cover plate buffer channel 160.
[0037] In an alternative form, there is one fixed seat 110, and the fixed seat 110 is provided with a vertical through hole. The through hole of the fixed seat 110 and the area between the plurality of guiding members 120 constitute the cover plate buffer channel 160.
[0038] When the cover plate 700 is located within the cover plate buffer channel 160, the edge of the cover plate 700 is in sliding contact with multiple guide members 120. Under the limiting action of the multiple guide members 120, it can only move up and down along the cover plate buffer channel 160, and cannot perform horizontal movement or rotation, thus ensuring the stability of the lifting and the accuracy of the position and angle.
[0039] The guide member 120 is a strip-shaped structure extending linearly in the vertical direction, and its cross-sectional shape can be circular, rectangular, triangular, elliptical, L-shaped, irregular shape, etc.
[0040] Preferably, the guide member 120 is a rod-shaped structure arranged vertically, and the cross-sectional shape of the guide member 120 includes a circle. Thus, the outer wall of the guide member 120 can be made smooth, making it easier for the cover plate 700 to slide relative to the guide rod. Moreover, the arc surfaces on different sides in the radial direction of the guide rod are the same. Therefore, when installing the guide member 120, any side in the radial direction of the guide rod can face the cover plate buffer channel 160, making the installation more convenient.
[0041] During the lifting process of the cover plate 700, the guide member 120 is in sliding contact with the cover plate 700. To extend the service life of the guide member 120, the material of the guide member 120 can be a wear-resistant metal material. For example, the material of the guide member 120 is stainless steel. In addition, the guide member 120 has a smooth outer wall to reduce the friction between the guide member 120 and the cover plate 700 and prevent the cover plate 700 from being worn.
[0042] The number of the guide members 120 can be 4, 6, 8, etc., and can be flexibly selected according to the shape of the cover plate 700 and the limiting requirements. For example, if the number of the guide members 120 is 6 and the number of the fixed seats 110 is 2, then 3 guide members 120 are arranged on one fixed seat 110, and the other 3 guide members 120 are arranged on the other fixed seat 110. The two fixed seats 110 and the guide members 120 distributed on the two fixed seats 110 are symmetric about a vertical plane. When the cover plate 700 is placed in the cover plate buffer channel 160, the length direction of the cover plate 700 is along the arrangement direction of the two fixed seats 110, and the width direction of the cover plate 700 is perpendicular to the arrangement direction of the two fixed seats 110. Two of the 3 guide members 120 on the same fixed seat 110 are in slidable contact with both sides in the width direction of the cover plate 700, and the other one is in slidable contact with one end in the length direction of the cover plate 700.
[0043] In some embodiments of the present disclosure, the cache guiding mechanism 100 further includes at least one first auxiliary support member 130 and / or at least one second auxiliary support member 140. The first auxiliary support member 130 is located outside the cover cache channel 160, and the first auxiliary support member 130 is fixedly connected to at least two guiding members 120 provided on both sides of the cover cache channel 160. For example, when there are two fixing seats 110, the second auxiliary support member 140 is fixedly connected to at least two guiding members 120 disposed on the upper sides of the two fixing seats 110 respectively. The second auxiliary support member 140 is located outside the cover cache channel 160, and the second auxiliary support member 140 is fixedly connected to at least two guiding members 120 located on the same side of the cover cache channel 106. For example, when there are two fixing seats 110, the second auxiliary support member 140 is fixedly connected to at least two guiding members 120 located on the upper side of the same fixing seat 110.
[0044] In this embodiment, the cache guiding mechanism 100 may be provided with only one of the first auxiliary support member 130 and the second auxiliary support member 140, or may be provided with both the first auxiliary support member 130 and the second auxiliary support member 140. Preferably, the cache guiding mechanism 100 is provided with both the first auxiliary support member 130 and the second auxiliary support member 140.
[0045] The first auxiliary support member 130 can connect the guiding members 120 on the same side to each other, and the second auxiliary support member 140 can connect the guiding members 120 on different sides to each other. By both the first auxiliary support member 130 and the second auxiliary support member 140, the stability can be increased, and the guiding members 120 can be prevented from shaking or bending.
[0046] Optionally, when the cache guiding mechanism 100 includes the first auxiliary support member 130, a plurality of first auxiliary support members 130 are provided, and the plurality of first auxiliary support members 130 are arranged at intervals in the vertical direction. Thus, the connection between the guiding rods on different sides can be realized at different height positions respectively.
[0047] Optionally, when the cache guiding mechanism 100 includes the second auxiliary support member 140, a plurality of second auxiliary support members 140 are provided, and some of the second auxiliary support members 140 are fixedly connected to at least two guiding members 120 located on one side of the cache channel 160, and the other part of the second auxiliary support members 140 are fixedly connected to at least two guiding members 120 located on the other side of the cache channel 160. Preferably, there are two fixing seats 110, and some of the second auxiliary support members 140 are fixedly connected to all the guiding members 120 on the upper side of one fixing seat 110, and the other part of the second auxiliary support members 140 are fixedly connected to all the guiding members 120 on the upper side of the other fixing seat 110.
[0048] In some embodiments of the present disclosure, the first auxiliary support member 130 is fixedly connected to the guide member 120, and the second auxiliary support member 140 is fixedly connected to the guide member 120. Exemplarily, the first auxiliary support member 130 and the second auxiliary support member 140 are respectively provided with a plurality of slots 150, the slots 150 penetrate the first auxiliary support member 130 or the second auxiliary support member 140 in the vertical direction, and the slots 150 have an opening on one side facing the cover plate cache channel 160, and the guide member 120 is connected to the first auxiliary support member 130 or the second auxiliary support member 140 through the slots 150.
[0049] The connection between the first auxiliary support member 130 and the second auxiliary support member 140 and the guide member 120 is achieved through the slot 150 structure, which has the advantages of easy installation and convenient adjustment of the installation position of the first auxiliary support member 130 and the second auxiliary support member 140 in the vertical direction, and is more flexible and convenient to use.
[0050] Combination Figure 1 and Figure 7 Optionally, the first auxiliary support member 130 includes a first component 131, a second component 132 and a third component 133, wherein the second component 132 and the third component 133 are respectively disposed at two ends of the first component 131 and are respectively vertically connected to the first component 131, and the second component 132 and the third component 133 extend in the same direction. A card slot 150 is respectively disposed at one end of the second component 132 away from the first component 131 and at one end of the third component away from the first component 131, and the card slot 150 located in the second component 132 is card-engaged with one of the guide members 120 on one of the fixing seats 110, and the card slot 150 located in the third component 133 is card-engaged with one of the guide members 120 on the other fixing seat 110.
[0051] Combination Figure 1 and Figure 8 Optionally, the second auxiliary support member 140 includes a fourth component 141, a fifth component 142 and a sixth component 143, wherein the fifth component 142 and the sixth component 143 are respectively disposed at two ends of the fourth component 141 and are respectively connected to the fourth component 141 vertically, and the fifth component 142 and the sixth component 143 extend in the same direction. A slot 150 is provided on one side of the fifth component 142 close to the sixth component 143, on one side of the sixth component 143 close to the fifth component 142, and on one side of the fourth component 141 facing the extending direction of the fifth component 142 and the sixth component 143. The slot 150 of the fourth component 141, the slot 150 of the fifth component 142, and the slot 150 of the sixth component 143 are respectively engaged with a plurality of guide members 120 on the same fixed seat 110 in a one-to-one correspondence.
[0052] The first auxiliary support member 130 and the second auxiliary support member 140 of the above structure are easy to connect and fix with the guide member 120, and after the first auxiliary support member 130 and the second auxiliary support member 140 are connected with the guide member 120, the first auxiliary support member 130 and the second auxiliary support member 140 are located on the outside of the cover plate cache channel 160, which can effectively avoid the first auxiliary support member 130 and the second auxiliary support member 140 from contacting with the cover plate 700 in the cover plate cache channel 160, and prevent the first auxiliary support member 130 and the second auxiliary support member 140 from affecting the lifting and lowering of the cover plate 700.
[0053] Combination Figure 1 and Figure 5 In some embodiments of the present disclosure, the fixed seat 110 includes a fixed plate 111 and a plurality of seat bodies 112. The fixed plate 111 is horizontally arranged and fixedly connected to the frame 11. The plurality of seat bodies 112 are fixedly arranged on the upper side of the fixed plate 111, and the seat body 112 is provided with a socket 113, and the socket 113 extends vertically to the upper end and the lower end of the seat body 112, and the seat body 112 is plugged and matched with the lower end of the guide member 120 through the socket 113. The plug-in fit between the seat body 112 and the guide member 120 can limit the guide member 120 and prevent the guide member 120 from moving or swinging. The plug-in connection method can make the installation of the guide member 120 more convenient, and it is also convenient to replace the guide member 120 when the guide member 120 is worn or deformed due to long-term work.
[0054] In some embodiments of the present disclosure, the seat body 112 has a movable groove 114 and a threaded hole 115 and a through hole 116 disposed on both sides of the movable groove 114 .
[0055] The movable groove 114 penetrates the seat body 112 in the vertical direction, one end of the movable groove 114 in the horizontal direction is connected to the insertion hole 113, and the other end in the horizontal direction extends to the side wall of the seat body 112. By providing the movable groove 114, the seat body 112 has the deformation ability of the parts located on both sides of the movable groove 114 approaching or moving away from each other. When the parts of the seat body 112 located on both sides of the movable groove 114 approach each other, the aperture of the insertion hole 113 is correspondingly reduced, and when the parts of the seat body 112 located on both sides of the movable groove 114 are moving away from each other, the aperture of the insertion hole 113 is correspondingly increased.
[0056] The threaded hole 115 extends in a horizontal direction, one end of the threaded hole 115 is connected to the movable groove 114, and the other end extends to the side wall of the seat body 112. The through hole 116 is axially aligned with the threaded hole 115, and one end of the through hole 116 facing the threaded hole 115 is connected to the movable groove 114, and one end of the through hole 116 away from the threaded hole 115 extends to the side wall of the seat body 112.
[0057] The fixing seat 110 further includes a plurality of locking bolts 117 , which correspond one to one with the plurality of seat bodies 112 . The locking bolts 117 are passed through the through holes 116 and the movable grooves 114 , and are threadedly connected to the seat bodies 112 through the threaded holes 115 .
[0058] After the lower end of the guide member 120 is inserted into the insertion hole 113, the locking bolt 117 can be tightened to elastically deform the seat body 112, thereby reducing the aperture of the insertion hole 113, so that the inner wall of the insertion hole 113 clamps the guide member 120, making the connection between the guide member 120 and the seat body 112 more secure. By loosening the locking bolt 117, the seat body 112 can be elastically reset, increasing the aperture of the insertion hole 113, and reducing the force of the inner wall of the insertion hole 113 on the guide member 120, thereby facilitating the removal of the guide member 120.
[0059] In some embodiments of the present disclosure, the lifting drive mechanism 300 includes a motor 310, a screw, a nut, a slide rail 320 and a slider 330. The motor 310 includes an output shaft. The screw is vertically arranged, connected to the output shaft, and rotatably connected to the frame 11. The nut is threadedly connected to the screw. The slide rail 320 is vertically arranged and fixedly connected to the frame 11. The slider 330 is slidably connected to the slide rail 320, and is fixedly connected to the nut and the cover plate support plate 200 respectively.
[0060] Optionally, the motor 310 in the lifting drive mechanism 300 is a servo motor, and the motor 310 is arranged at one side of the bottom of the cache guide mechanism 100. The output shaft of the motor 310 is arranged vertically upward, and is connected to the screw through a transmission structure such as a connecting shaft, a gear set or a synchronous belt. The screw is arranged vertically and is rotatably connected to the frame 11 through a bearing. When the motor 310 is running, it can drive the screw to rotate axially, and then drive the slider 330 to move vertically along the slide rail 320 through a nut. When the slider 330 moves vertically, the cover plate support plate 200 can be moved vertically in the cover plate cache channel 160.
[0061] Alternatively, if Figure 6 As shown, the cover plate support plate 200 includes a first plate body 210, a second plate body 220 and a third plate body 230. The first plate body 210 is vertically arranged and detachably connected to the slider 330 by structures such as bolts and buckles. The second plate body 220 is horizontally arranged and located in the cover plate buffer channel 160. The side of the second plate body 220 facing the slider 330 is fixedly connected to the upper end of the first plate body 210. The third plate body 230 is vertically arranged and vertically fixed to the first plate body 210 and the second plate body 220 respectively. The cover plate support plate 200 of this structure has the advantages of stable support, good load-bearing capacity, light weight and low production cost.
[0062] Optionally, the third plate body 230 is provided with a hollow hole that penetrates the third plate body 230. By means of the hollow hole, the material used for the third plate body 230 can be reduced, thereby reducing the weight and production cost of the third plate body 230.
[0063] Combined with Figures 1 to 3 , in some embodiments of the present disclosure, the buffer device 10 further includes a first sensor 400. The first sensor 400 is communicatively connected to the lifting drive mechanism 300. The first sensor 400 is configured to detect whether the lifting drive mechanism 300 is at the origin position. The lifting drive mechanism 300 is configured to perform operation control according to the detection signal of the first sensor 400. Specifically, the signal acquisition position of the first sensor 400 is at the lower end of the stroke of the output end of the lifting drive mechanism 300, for example, at the lower end of the sliding stroke of the slider 330. The first sensor 400 can be a photoelectric sensor or a proximity switch, etc. Taking the first sensor 400 as a groove-type photoelectric sensor as an example, the detection groove of the groove-type photoelectric sensor is located on one side of the lower end of the sliding stroke of the slider 330, and the sensing piece of the groove-type photoelectric sensor is fixedly connected to the slider 330. When the sensing piece moves with the slider 330 into the detection groove, the groove-type photoelectric sensor generates a detection signal, and at this time, the lifting drive mechanism 300 reaches the origin position. The detection of the origin position can provide a position reference for the operation of the lifting drive mechanism 300 and ensure the accuracy of the moving position of the cover plate 700.
[0064] In some embodiments of the present disclosure, the buffer device 10 further includes a second sensor 500. The second sensor 500 is located on one side of the cover plate inlet and outlet. The second sensor 500 is communicatively connected to the lifting drive mechanism 300. The second sensor 500 is configured to detect whether there is a cover plate 700 at the cover plate inlet and outlet position. The lifting drive mechanism 300 is configured to perform operation control according to the detection signal of the second sensor 500. The second sensor 500 can be a laser sensor, for example, a transmissive laser sensor. The laser sensor is arranged at the cover plate inlet and outlet position. When there is a cover plate 700 at the cover plate inlet and outlet position, the second sensor 500 generates a detection signal, and the lifting drive mechanism 300 performs operation control based on the detection signal of the second sensor 500. For example, during the process of storing the cover plate 700 in the buffer device 10, when the second sensor 500 detects that there is a cover plate 700 at the cover plate inlet and outlet position, the lifting drive mechanism 300 operates to drive the cover plate support plate 200 to descend by a distance equal to the thickness of one cover plate 700, so as to facilitate the handling device 20 to continue to place the cover plate 700 at the cover plate inlet and outlet, and so on until the lifting drive mechanism 300 reaches the origin position; during the process of supplying the cover plate 700 through the buffer device 10, when the second sensor 500 detects that there is a cover plate 700 at the cover plate inlet and outlet position, the lifting drive mechanism 300 stops driving the cover plate support plate 200 to rise, so as to facilitate the handling device 20 to take out the cover plate 700 at the cover plate inlet and outlet position, and so on, to realize the continuous supply of the cover plate 700.
[0065] In some embodiments of the present disclosure, the buffer device 10 further includes a third sensor 600. The third sensor 600 is located below the cover buffer channel 160 and is used to detect whether there is a cover 700 in the cover buffer channel 160. The lifting drive mechanism 300 is configured to perform operation control according to the detection signal of the third sensor 600. The third sensor 600 can be, for example, a diffuse reflection photoelectric sensor, etc. When there is no cover 700 in the cover buffer channel 160, the third sensor 600 generates a detection signal, and the lifting drive mechanism 300 performs operation control according to this detection signal. Specifically, when the third sensor 600 detects that there is a cover 700 in the cover buffer channel 160, the lifting drive mechanism 300 stops driving the cover tray 200 to rise. At this time, the cover 700 can be stored in the cover buffer channel 160 through the handling device 20.
[0066] Combined with Figure 9 , an embodiment of the present disclosure further provides a sheet processing device 1. The sheet processing device 1 includes the above-mentioned buffer device 10 and a handling device 20. The handling device 20 is used to transport the cover 700 to the cover inlet and outlet position, or to remove the cover 700 located at the cover inlet and outlet position. The handling device 20 can be a six-axis robot, etc., and no specific limitation is made here.
[0067] Optionally, when the buffer device 10 includes a first sensor 400, the handling device 20 is communicatively connected to the first sensor 400, and the handling device 20 is configured to perform operation control based on the detection signal of the first sensor 400. For example, during the process of storing the cover 700 in the buffer device 10, when the first sensor 400 detects that the lifting drive mechanism 300 reaches the origin position, the handling device 20 stops putting the cover 700 into the buffer device 10.
[0068] Optionally, when the buffer device 10 includes a second sensor 500, the handling device 20 is communicatively connected to the second sensor 500, and the handling device 20 is configured to perform operation control based on the detection signal of the second sensor 500. For example, during the process of storing the cover 700 in the buffer device 10, when the second sensor 500 detects that there is a cover 700 at the cover inlet and outlet position, the handling device 20 interrupts the operation of putting the next cover 700 into the cover inlet and outlet. When the second sensor 500 detects that there is no cover 700 at the cover inlet and outlet position, the handling device 20 continues to put the next cover 700 into the cover inlet and outlet; during the process of supplying the cover 700 through the buffer device 10, when the second sensor 500 detects that there is a cover 700 at the cover inlet and outlet position, the handling device 20 takes out the cover 700 at the cover inlet and outlet position.
[0069] Optionally, when the cache device 10 includes a third sensor 600, the handling device 20 is communicatively connected to the third sensor 600, and the handling device 20 is configured to perform operation control based on the detection signal of the third sensor 600. For example, during the process of supplying the cover plate 700 by the cache device 10, when the third sensor 600 detects that there is a cover plate 700 in the cover plate cache channel 160, the handling device 20 performs an action of taking out the cover plate 700 at the cover plate inlet and outlet position, and when the third sensor 600 detects that there is no cover plate 700 in the cover plate cache channel 160, the handling device 20 starts to perform an action of storing the cover plate 700 into the cache device 10.
