Description

Technical Field

[0001] The utility model relates to the field of silicon wafer processing, in particular to a scraping device and a scraping system provided with the device. Background Art

[0002] Before slicing the silicon rod, the silicon rod 100 needs to be glued to the material plate 200, and the material plate 200 is then glued to the material holder 300 (such as Figure 1 As shown), and then cut with diamond wire. Grooves 301 are generally provided on both sides of the material holder 300, and the grooves 301 are used for positioning when slicing. During the gluing process, the glue will be squeezed and overflow, and the overflowed glue will hang on the side of the material holder and the bottom wall of the slot; and in the slicing process, the glue hanging on the material holder will be washed by the cutting fluid and fall on the wire mesh, causing the diamond wire to break. In this way, not only will the cost of the diamond wire in the slicing process be greatly increased, but the product yield of the battery cell cutting will also be reduced due to the breakage of the diamond wire; furthermore, after the diamond wire is broken, it is necessary to stop the machine for rewiring the diamond wire, which also greatly affects the production efficiency.

[0046] like Figures 1 to 10 As shown, the utility model discloses a scraping device, which can scrape off the overflowed glue at a specified position on the material holder 300, and the scraping device includes:

[0047] The positioning device 1 is configured to position the material holder 300 at a preset position;

[0048] Two spaced apart scraper assemblies 2 are configured to reciprocate in a first direction;

[0049] A first driving device 3 connected to the two scraper assemblies 2;

[0050] After the positioning device 1 positions the material holder 300 at the preset position, the two scraping components 2 are driven by the first driving device 3 to move in the first direction to scrape off the overflowed glue at the designated positions on both sides of the material holder 300 .

[0051] In this embodiment, the two scraper assemblies 2 are further configured to be movable relatively closer to or farther from each other in a second direction, and the first direction is perpendicular to the second direction.

[0052] Preferably, the two scraping assemblies 2 are arranged relative to each other, so that the two scraping assemblies 2 can move in the scraping direction at the same position to perform scraping.

[0053] The material holder 300 is transported in the first direction by a transport device 4, and the transport device 4 includes two brackets 41 and a plurality of transport members 42 connected to the two brackets 41. The plurality of transport members 42 are spaced apart in the first direction, or / and, the plurality of transport members 42 are spaced apart in the second direction, so that there are gaps between adjacent transport members 42; the material holder 300 is placed on the transport member 42 and is transported as the transport member 42 moves.

[0054] In this embodiment, the conveying device 4 is configured as a roller-type conveying device, namely, it includes a plurality of rollers 42 (i.e., conveying members) spaced apart along a first direction. Each roller 42 is rotatably connected to two brackets 41 on either side, with a gap between adjacent rollers. In other embodiments, the conveying device 4 may include two sets of conveying members 42 spaced apart along a second direction, with each set of conveying members 42 connected to a bracket 41 on a corresponding side, thereby creating a gap between the two sets of conveying members 42 in the first direction. The conveying device 4 may also have any other known and feasible structure, as long as the aforementioned gap exists between adjacent conveying members 42.

[0055] Preferably, the positioning device is further configured to position the material holder in a horizontal state when it positions the material holder in a preset position.

[0056] The positioning device 1 includes at least two sets of positioning assemblies 11 spaced apart along a first direction. Each set of positioning assemblies 11 includes a positioning member 12 supported at the bottom of the material holder 300 and a second drive device 13 connected to the positioning member 12 and capable of driving the positioning member 12 to move up and down. The positioning member 12 includes a main body 121 and a positioning portion 122 extending upward from the middle of the upper end of the main body 121. Correspondingly, a positioning slot 304 is recessed in the middle of the lower end of the material holder 300 for the positioning portion 122 to extend into. The upper end surfaces of the positioning member main body 121 located on either side of the positioning portion 122 match the shape of the lower end surface of the material holder 300. Therefore, when the upper end surfaces of the front and rear positioning member main bodies 121 located on either side of the positioning portion 122 are supported on the upper end surfaces located on either side of the positioning portion 122, the entire material holder can be horizontal in the front-to-back direction. In this embodiment, because the lower end surface of the material holder 300 is flat, the upper end surfaces of the positioning member main body 121 located on either side of the positioning portion 122 are correspondingly configured as flat.

[0057] Each positioning member 12 is positioned between two adjacent conveying members 42 in a relatively vertically movable manner, and the width and length of the positioning member 12 are respectively smaller than the corresponding dimensions of the gap between the two adjacent conveying members 42. This arrangement ensures that the positioning member 12 does not interfere with the conveying members 42 during its vertical movement. With this arrangement, if the conveying members 42 of an existing conveying device 4 are spaced apart with gaps that do not interfere with the vertical movement of the positioning member 12, the positioning device 1 can be installed without modifying the existing conveying device 4.

[0058] In this embodiment, the positioning slot 304 is elongated and extends along the first direction. Thus, after the two positioning portions 122 are engaged with the positioning slot 304, the material holder cannot move in the second direction, but can still move in the first direction. Therefore, the positioning assembly further includes a blocking device (not shown). The blocking assembly includes a blocking member and a driving device (which can be a cylinder) for driving the blocking member to move. When the material holder is transferred to a preset position, the cylinder drives the blocking member to move and block the front end of the material holder in the scraping direction (not shown). Because the scraping assembly 2 generates a thrust toward the front of the material holder in the scraping direction when scraping glue, the blocking member blocks the front end of the material holder in the scraping direction, preventing the material holder from moving forward in the scraping direction, thereby being positioned.

[0059] In other embodiments, the positioning slots 304 may be provided at the lower end of the material holder at positions corresponding to the positioning portions 122 of the two positioning members, so that after the two positioning portions 122 are inserted into the corresponding positioning slots 304, the material holder is positioned so as to be unable to move or rotate in the first direction and the second direction.

[0060] The second drive device 13 is configured as a cylinder, the piston rod of which is connected to the underside of the positioning member 12. The second drive device 13 is connected to a connecting seat 14. Preferably, two hollow guide members 15 are connected to the connecting seat 14 and are located on either side of the second drive device 13. Correspondingly, two connecting rods 16 can move up and down along the hollow guide members 15, and the upper ends of the two connecting rods 16 are respectively connected to the two sides of the positioning member 12 main body 121 in the second direction. The piston rod of the cylinder 13 is connected to the middle of the positioning member main body 121. Furthermore, the two connecting rods 16 are symmetrical with respect to the piston rod of the cylinder 13. With such an arrangement, when the cylinder is working and the piston rod pulls the positioning member 12 to move up and down, the cooperation between the guide member 15 and the connecting rod 16 can prevent the positioning member 12 from rotating, so that when the positioning member 12 is pulled to move downward, it can avoid the situation where it cannot move up and down between adjacent conveying members 42 due to rotational deviation; and when the upper end surface of the main body 121 of the positioning member 12 is supported on the lower end of the material holder 300, the supporting force of the two sides of the main body 121 on the lower end of the material holder 300 is more uniform.

[0061] The scraper device further includes two mounting frames 5 and two mounting seats 6 spaced apart in the second direction. Each mounting seat 6 is connected to the mounting frame 5 on the corresponding side so as to be reciprocatable along the first direction. Each scraper assembly 2 is connected to the mounting seat 6 on the corresponding side so as to be movably along the second direction. In other words, the scraper assembly 2 is able to reciprocate along the first direction via the mounting frames 5.

[0062] The two mounting frames 5 are respectively arranged on the outsides of the two brackets of the transmission device 4 , that is, the transmission device 4 is arranged between the two mounting frames 5 .

[0063] Preferably, each of the mounting frames 5 is provided with a first guide rail 50 extending in the same direction as the first direction. Correspondingly, the lower side of the mounting seat 6 is connected with a first slider 60 that can cooperate with the guide rail. Through the cooperation of the first guide rail 50 and the first slider 60, the movement of the mounting seat 6 can be smoother and not deviated, thereby ensuring that the scraper assembly 2 does not shift during the scraping process.

[0064] In this embodiment, each of the mounting frames 5 is provided with two first guide rails 50 spaced apart in the second direction, and correspondingly, two spaced apart first sliding blocks 60 are connected to the lower side of each of the mounting seats 6 .

[0065] Preferably, the first drive device 3 includes a power supply device 31 and a synchronous transmission device connected to the power supply device 31. The synchronous transmission device is also connected to the two mounting bases 6. When the power supply device 31 is in operation, the synchronous transmission device can drive the mounting bases 6 to move synchronously, thereby driving the two scraper assemblies 2 to move synchronously. This synchronous drive method can better control the movement of the two scraper assemblies 2. Moreover, when the material base 300 is positioned, the two synchronously moving scraper assemblies 2 are equivalent to being in symmetrical positions on both sides of the material base 300. Therefore, during the process of scraping glue, the two scraper assemblies 2 apply the same force to the symmetrical positions on both sides of the material base 300. This further prevents the material base 300 from tilting due to uneven force during the scraping process, thereby better scraping away excess glue at designated locations on both sides of the material base 300.

[0066] In this embodiment, the power supply device 31 is configured as a motor, and the synchronous transmission device includes a driving wheel connected to the motor output shaft, a first rotating shaft 51 rotatably connected to the mounting brackets 5 on both sides, a first driven wheel connected to the first rotating shaft 51, a first synchronous belt 52 connecting the driving wheel and the first driven wheel, two second driven wheels connected to the first rotating shaft 51 on both sides, and two sets of transmission structures respectively provided on the two mounting brackets 5. The transmission structure on each mounting bracket 5 includes a second rotating shaft 52 and a third rotating shaft 53 rotatably connected to the mounting bracket 5 on both sides in the first direction, a third driven wheel and a fourth driven wheel 54 connected to the second rotating shaft 52, a fifth driven wheel 55 connected to the third rotating shaft 53, and a second synchronous belt (not shown) connecting the fourth driven wheel 54 and the fifth driven wheel 55. The third synchronous belt 56 is also fixedly connected to the mounting bracket 6. The third driven wheel on each side is connected to the second driven wheel on the corresponding side via the third synchronous belt 56.

[0067] When the motor 31 is working, the first rotating shaft 51 is driven to rotate through the cooperation of the driving wheel, the first synchronous belt 52 and the first driven wheel; and when the first rotating shaft 51 rotates, the two second driven wheels rotate together, and with the cooperation of the third synchronous belt 56 on each side and the second driven wheel and the third driven wheel on the corresponding side, the second rotating shaft 52 on the corresponding side mounting frame 5 is driven to rotate, so that the fourth driven wheel 54 on the second rotating shaft 52 rotates; with the cooperation of the fourth driven wheel 54, the second synchronous belt and the fifth driven wheel 55, the left and right mounting seats 6 are pulled by the second synchronous belt and move synchronously.

[0068] Combine Figure 1 、 6As shown in Figures 8 and 9, the mounting seat 6 is provided with a cavity 61 extending through the first direction, and a synchronous belt connecting device 62 for being fixedly connected to the second synchronous belt is provided in the cavity 61. In this embodiment, the synchronous belt connecting device 62 includes a lower abutment 621 and an upper abutment 622, and a friction member 623 is provided on the upper side of the lower abutment 621 or the lower side of the upper abutment 622. The lower side of the second synchronous belt passes through the gap between the two first sliders 60, and the upper side passes between the lower abutment 621 and the upper abutment 622 in the cavity 61. The lower abutment 621 and the upper abutment 622 are then fixed to the bottom wall of the cavity 61 by screws 624 or other feasible methods. Due to the arrangement of the friction member 623 , after the lower abutment member 621 and the upper abutment member 622 are relatively fixed, the portion of the second synchronous belt passing therebetween is relatively fixedly connected to the synchronous belt connecting device 62 , that is, relatively fixedly connected to the mounting seat 6 .

[0069] In other embodiments, the synchronous transmission device may also adopt any other known and feasible structure, as long as it can achieve the above-mentioned function of driving the left and right mounting seats 6 to move synchronously.

[0070] The scraper assembly 2 includes a tool holder 22, a tool base 23 connected to the tool holder 22, and a scraper 21 connected to the tool base 23. The tool holder 22 can be movably connected to the mounting seat 6 along the second direction; the scrapers 21 of the two scraper assemblies 2 are respectively connected to the opposite sides of the two scraper assembly tool bases 23.

[0071] Preferably, the scraper 21 is connected to the end of the blade holder 23 that faces the direction of the scraping process. That is, if the blade holder 23 moves forward to scrape the glue, the scraper 21 is connected to the front end of the blade holder 23; if the blade holder 23 moves backward to scrape the glue, the scraper 21 is connected to the rear end of the blade holder 23. This arrangement allows the blade holder 23 to share the force exerted on the scraper 21 during scraping, thereby extending the service life of the scraper 21.

[0072] Combine Figure 6 、 7 As shown, further, the blade holder 23 is provided with a mounting groove 231 at one end facing the scraping direction, and at least one side of the scraper 21 facing away from the scraping direction is located in the mounting groove 231, so that the scraper 21 and the blade holder 23 are better positioned and assembled more conveniently. Moreover, because the side wall of the mounting groove 231 in the second direction contacts the side wall of the scraper 21 on the corresponding side, the scraper 21 is not easy to rotate relative to the blade holder 23 during the scraping process. Preferably, as Figure 10As shown in Figure B, the side wall of the mounting groove 231 in the second direction and the side wall on the corresponding side of the scraper 21 are set to a matching broken line shape, so that the connection between the scraper 21 and the blade holder 23 is more stable, and the scraper 21 is less likely to rotate relative to the blade holder 23, thereby further ensuring the stability of the scraper 21 in the process of scraping glue, and thus ensuring the scraping effect.

[0073] Both the blade holder 23 and the blade carrier 22 are provided with connecting holes. Preferably, the connecting holes in the blade holder 23 and / or the blade carrier 22 are configured as elongated connecting holes 232 extending in the second direction. To connect the blade holder 23 and the blade carrier 22, the blade holder 23 can first be moved in the second direction, and then connected to the blade carrier 22 via the connecting holes using screws or rivets. This arrangement allows the position of the scraper 21 in the second direction to be adjusted while the entire scraper assembly moves in the second direction. This allows the present invention to accommodate material holders 300 and conveyor devices 4 of varying widths, broadening its adaptability.

[0074] Furthermore, the tool holder 22 is configured to be L-shaped, the tool seat 23 is connected to the transverse portion 221 of the L-shaped tool holder 22, and the third drive device 7 is connected to the vertical portion 222 of the L-shaped tool holder 22; the transverse portion of the L-shaped tool holder 22 is connected to the second slider 24.

[0075] Preferably, each scraper assembly 2 is equipped with a corresponding number of blade holders 23 to the number of designated locations on each side of the material holder 300 for scraping excess glue. Each blade holder 23 is connected to a scraper at a corresponding location. In other words, one blade holder 23 plus one scraper 21 scrapes excess glue at one designated location. This arrangement makes it easier to replace the blade holders 23 and scrapers 21.

[0076] In this embodiment, there are two designated locations for scraping off the overflow glue on each side of the material holder 300, one is the bottom wall 303 of the groove, and the other is the outer wall 302 above the groove 301 (such as Figure 1 corresponding to the two designated positions, the utility model scraper assembly 2 includes two knife holders 23, each knife holder 23 is connected to a scraper 21, and the blade of one scraper 21 faces downward and faces the bottom wall 303 of the groove, and the blade of the other scraper 21 faces the outer wall 302 of the upper portion of the groove 301.

[0077] The present invention's scraper device also includes two third drive devices 7, each connected to the two scraper assemblies 2, to drive the two scraper assemblies 2 to move relatively closer or farther in the second direction. Each of the third drive devices 7 is connected to the mounting base 6 on the corresponding side. The third drive device 7 is connected to the tool holder 22. In this embodiment, the third drive device 7 is also configured as a cylinder, the piston rod of which is connected to the tool holder 22. Preferably, the mounting base 6 is provided with a second guide rail 65 extending in the second direction, and correspondingly, the tool holder 22 is connected to a corresponding second slider 24.

[0078] The mounting seat 6 includes a movable portion 63 and an actuating portion 64 extending from one upper end of the movable portion 63 toward the other mounting seat 6. The movable portion 63 is connected to the mounting frame 5, and the actuating portion 64 is located above the bracket 41 on the same side. Therefore, when the mounting seat 6 and the squeegee assembly reciprocate in the first direction, they will not interfere with the transmission device 4.

[0079] In this embodiment, each of the scraping components 2 is provided with a dust cover 8, and the dust cover 8 is opened in the direction of the material holder 300. In this way, the dust generated by the scraper 21 and the scraped glue debris can fall into the dust cover 8 during the scraping process, thereby maintaining a hygienic environment during the scraping process.

[0080] A gap is formed between the lower end of the operating portion 64 and the upper end of the bracket 41. The dust cover 8 extends through the second direction, with the bottom wall of the dust cover 8 located at the lower end of the operating portion 64 and the top wall located above the upper end of the blade holder 22 (i.e., the upper end of the vertical portion 222 of the L-shaped blade holder 22), i.e., the top wall located above the scraper assembly. This arrangement makes the dust cover 8 easier to install and remove.

[0081] Combine Figure 11 、 12 As shown, further, the scraper device also includes a frame 400, the two mounting frames 5 are relatively fixedly connected to the frame 400, the two connecting seats 14 can be fixedly connected to the frame 400, and can also be relatively fixedly connected to the two brackets 41 of the transmission device respectively; the two brackets 41 of the transmission device can also be fixedly connected to the frame 400 by any known and feasible method.

[0082] The utility model also discloses a scraping system, which includes the scraping device or the scraping device and the transmission device 4 .

[0083] The scraping system also includes a detection device for detecting whether the overflow glue at the designated positions on both sides of the material holder has been scraped off. The detection device is configured as a visual detection device, which includes a plurality of cameras 500 and a controller 600 connected to each other; the plurality of cameras 500 can take pictures of both sides of the silicon rod and transmit the pictures to the controller 600; the controller 600 stores pictures of the material holder scraping glue that meets the requirements, and can compare the pictures transmitted by the camera 500 with the pictures stored therein to analyze whether the overflow glue at the designated position of the material holder has been scraped off. The specific working principle of the visual detection device is a conventional operation in this field and will not be described in detail here. The plurality of cameras 500 and the controller 600 are both connected to the frame 400.

[0084] Preferably, the scraping system further includes an industrial computer 700 and a display 800, and the controller 600 is also connected to the industrial computer 700. The comparison and analysis results of the controller 600 are displayed on the display 800 via the industrial computer 700, thereby facilitating viewing by operators.

[0085] The scraping system further includes a keyboard 900 connected to the display screen 800 and the industrial computer 700, or the display screen 800 is configured as a touch screen display.

[0086] Preferably, the controller 600 is disposed in a control cabinet 400 , and the control cabinet 400 , the industrial computer 700 and the display 800 are also connected to the rack 400 .

[0087] The industrial computer 700 is also connected to the first drive device 3, the second drive device 13, and the third drive device 7, so as to control the operation of each drive device, and further control the above-mentioned scraping operation and detection operation.

[0088] Preferably, the scraping system further comprises an alarm 601 connected to the controller, which sounds an alarm when there is a problem with the scraping operation or the detection result does not meet the requirements. The alarm 601 can be an audible alarm and / or a light alarm.

[0089] The following uses the example of the material holder 300 being transported from back to front and the scraper 21 moving from front to back to scrape the glue as an example (i.e., the first direction is the front-to-back direction, and the second direction is the left-to-right direction) to illustrate the working principle of the scraping system of the present invention:

[0090] When the material holder 300 bonded to the crystal ingot 100 and the material plate 200 has not yet been transferred to the preset position, the left and right scraper assemblies move relatively away from each other as the mounting base 6 is driven by the third driving device 7 on the corresponding side, thereby reserving space for the material holder 300 to pass through. Under the drive of the power supply device 31, the left and right scraper assemblies are located behind the preset position; the positioning member 12 is driven by the second driving device 13 to move downward to a position not higher than the conveying member 42, so as not to affect the normal conveyance of the material holder 300;

[0091] When the material holder 300 is conveyed to the preset position, the two second driving devices 13 work, respectively driving the two positioning members 12 to move upward, so that the positioning parts 122 on the upper sides of the two positioning members 12 extend into the positioning slots 304 at the lower end of the material holder 300, and the upper end surfaces of the positioning member body 121 on both sides of the positioning parts 122 will be supported on the lower end surface of the material holder 300. As the second cylinder continues to work, the material holder 300 will be lifted up and separated from the conveying member 42 until the heights of the parts to be scraped on both sides of the material holder 300 correspond to the height positions of the scrapers 21 on both sides, that is, the bottom walls of the slots on both sides of the material holder 300 correspond to the height positions of the blades of the second scraper 21. , the outer wall of the portion of the material holder 300 located above the slot corresponds to the height position of the blade of the first scraper 21; and because the material holder 300 is supported at the bottom by the front and rear positioning members 12, the material holder 300 as a whole is in a horizontal state in the first direction. Therefore, through the positioning device, not only the material holder 300 is positioned at the preset position but also the material holder 300 as a whole is in a horizontal state; at this time, the second driving device 13 stops working, and the two third driving devices 7 start working, driving the two knife holders 23 to move relative to each other until the blade of the first scraper 21 is located on the rear side of the outer wall of the portion above the slot, and the blade of the second scraper 21 is located on the rear side of the bottom wall of the material holder groove 301;

[0092] At this time, the power supply device 31 works, driving the left and right mounting seats 6 to move forward through the synchronous transmission device, thereby driving the scraper 21 on the mounting seat 6 to move forward. In the process of the scraper 21 moving forward, the blade of the first scraper 21 scrapes off the glue on the outer wall 302 of the material seat 300 above the groove 301, and the blade of the second scraper 21 scrapes off the glue on the bottom wall 302 of the groove; until the scraper 21 passes over the material seat 300, the overflow glue at two designated positions on the material seat 300 is scraped off.

[0093] When the scraper 21 moves over the material holder 300, the power supply device 31 stops working, and the third drive device 7 works to drive the two knife holders 23 to move in the opposite direction and away from the material holder 300. At the same time, the second drive device 13 works to pull the positioning member 12 down to a position not higher than the conveying member 42, so that the material holder 300 returns to the transmission device 4 and is driven forward by the transmission device 4; and the power supply device 31 also works again, and drives the left and right mounting seats 6 to move backward to the rear of the preset position through the synchronous transmission device, waiting for the arrival of the next material holder 300.

[0094] If after the material holder is positioned, if the scraping assembly moves from front to back to scrape the glue, the principle is the same as above.

[0095] After the scraping operation is completed, as the material holder continues to be transported, the cameras 500 take pictures of both sides of the silicon rod and upload the pictures to the controller 600. The controller 600 stores pictures of the material holder scraping that meet the requirements. After receiving the pictures from the cameras 500, the controller 600 compares them with the pictures stored therein to analyze whether the overflowed glue at the specified position of the material holder has been scraped off. The comparison and analysis results are displayed on the display 800 through the industrial computer 700, so that the operator can view them easily.

[0096] If the overflow glue at the designated position of the material holder is not completely removed, the scraping operation is repeated according to the scraping operation until the overflow glue at the designated position of the material holder is not completely removed.
