Description

Technical Field

[0001] The utility model relates to the field of high-hard and brittle material processing, in particular to a row of rod assemblies, and a rod splicing and sticking system provided with the row of rod assemblies. Background Art

[0002] In the field of high-hard and brittle material processing, when slicing materials, it is usually necessary to bond the materials to a workpiece plate, and then place the workpiece plate with the bonded materials in an automatic slicing device for slicing processing.

[0003] In the processing of high-hard and brittle materials, for some small-sized and thin-thickness material blocks (such as material blocks cut from scraps such as side skins and head and tail materials), the efficiency of slicing processing alone is poor. To improve the slicing efficiency, it is usually necessary to perform rod splicing, that is, splicing multiple small material blocks together to form a whole rod, bonding and curing it with a workpiece plate, and then processing the spliced material rod through a slicing device.

[0004] In the process of using an automated device for rod splicing and sticking, the device will adjust the placement position of the material blocks, and then transfer and arrange the material blocks in a row to form a pre-bonded group of material blocks. When the sizes of the material blocks to be spliced are small and the quantity is large, the existing devices not only have low rod arranging efficiency, but also the structural design of the clamping components is unreasonable, making it difficult to automatically reduce the spacing between multiple material blocks to within the splicing requirements, and unable to achieve efficient and fully automated production and processing. In addition, when multiple material blocks are arranged in a row, problems such as shaking or tilting and collapsing are likely to occur. Summary of the Utility Model

[0069] In order to better understand the purpose, structure and function of the present utility model, the stick arranging component and the stick splicing and gluing system of the present utility model will be described in detail below with reference to the accompanying drawings.

[0070] As Figure 1 and Figure 2 shown, the stick splicing and gluing system in the present utility model is used for automatically arranging, gluing and curing silicon blocks with small volume and thin thickness, so that multiple small silicon blocks are automatically integrated into a larger and integral silicon block rod, preparing for the subsequent slicing process.

[0071] Such silicon blocks with small volume and thin thickness can be cut and processed from the edge scraps generated during the process of squaring silicon rods, or can be cut and processed from the head and tail scraps generated during the process of truncating silicon rods. Since the edge scraps and head and tail scraps like this are usually small in volume and irregular in shape, the silicon blocks cut from them have the characteristics of small volume and thin thickness. In order to improve the subsequent slicing efficiency, multiple small silicon blocks can be spliced and integrated through the stick splicing and gluing system of the present utility model to form a large and long silicon block rod, and then be processed by an automatic slicing device for automatic slicing. Of course, similar small silicon blocks generated by other means can also be spliced and integrated through the stick splicing and gluing system of the present utility model, not limited to the small silicon blocks processed from edge scraps and head and tail scraps. In addition to silicon rods, other high-hard and brittle materials, such as sapphire, ceramics, etc., can also be spliced and integrated by using the stick splicing and gluing system of the present utility model.

[0072] Specifically, as Figure 1 and Figure 2As shown in the figure, the stick - assembling and sticking system includes a stick - assembling unit 1, a glue - applying unit 2 and a curing unit 3 which are cooperatively arranged. Among them, the stick - assembling unit 1 is used to detect whether the size of the silicon blocks is qualified, and arrange the qualified silicon blocks to form a group of silicon blocks with a certain length in a row; the glue - applying unit 2 can transport the workpiece plate for bonding small silicon blocks and automatically apply glue to the workpiece plate; the curing unit 3 is used to pick up the arranged group of silicon blocks and the workpiece plate coated with glue respectively, and bond and cure the two to form a silicon - block rod. The stick - assembling unit 1, the glue - applying unit 2 and the curing unit 3 can work in parallel simultaneously, so as to quickly and automatically integrate multiple silicon blocks into a silicon - block rod convenient for slicing.

[0073] Preferably, the above - mentioned stick - assembling and sticking system is used for automatically arranging multiple small silicon blocks at equal intervals. For the spliced silicon - block rod, since there will be gaps between adjacent two silicon blocks, during slicing processing, the cutting wire mesh for slicing needs to be specially configured so that the cutting positions of the cutting wire mesh can match the multiple gaps on the silicon - block rod. The equal - interval automatic arrangement method can make it more convenient to configure a suitable cutting wire mesh for the silicon - block rod. Especially when performing batch slicing processing, the cutting wire mesh does not need to be readjusted repeatedly, which helps to further improve production efficiency and ensure slicing quality.

[0074] Furthermore, as Figure 3 and Figure 4 shown, the stick - assembling unit 1 includes a feeding mechanism, a centering platform and a rod - arranging component. Among them, the feeding mechanism is used to load the silicon blocks and automatically complete the detection of the thickness of the silicon blocks during the loading process. The silicon blocks with qualified thickness will be transported to the centering platform; multiple silicon blocks can be placed on the centering platform, and the centering platform can adjust the placement position of the silicon blocks for the first time and transfer multiple silicon blocks to the rod - arranging component at the same time; the rod - arranging component picks up multiple silicon blocks on the centering platform at the same time, adjusts the placement position of the silicon blocks for the second time, reduces the distance between multiple silicon blocks, and then places the multiple silicon blocks with adjusted distance on the stick - assembling platform. When the rod - arranging component adjusts the next group of silicon blocks, it sequentially places the next group of silicon blocks in front of or behind the previous group of silicon blocks, so that the front and rear groups of silicon blocks are continuously placed. By repeating the above operations, the feeding mechanism, the centering platform and the rod - arranging component can arrange multiple small silicon blocks into a group of silicon blocks in a row with a length sufficient to be spliced into a whole rod.

[0075] Furthermore, as Figures 4 to 7As shown, the material distribution mechanism includes a material distribution fixture 11, a detection component 12, a feeding conveyor line 13 and an NG conveyor line 14. The detection component 12 is arranged close to the feeding conveyor line 13, and the material distribution fixture 11 is movably arranged above the feeding conveyor line 13 and the NG conveyor line 14. The silicon block is placed on the feeding conveyor line 13, and the feeding conveyor line 13 can drive the silicon block to move. When the silicon block moves to the detection component 12, the detection component 12 can detect the thickness of the silicon block and determine whether the thickness of the silicon block is within a preset error range. After completing the thickness detection, the feeding conveyor line 13 continues to drive the silicon block to move to the material distribution fixture 11, and the material distribution fixture 11 clamps the silicon block to make the silicon block separate from the feeding conveyor belt. According to the detection results of the detection component 12, if the thickness of the silicon block exceeds the preset error range, it means that the silicon block does not meet the requirements of the rod assembly and sticking. At this time, the material dividing fixture 11 carries the silicon block to the top of the NG conveyor line 14 and places the silicon block on the NG conveyor line 14. The NG conveyor line 14 can move the silicon blocks whose sizes do not meet the requirements out of the material dividing mechanism; if the thickness of the silicon block is within the preset error range, the material dividing fixture 11 will carry the silicon block into the subsequent rod arrangement process.

[0076] Furthermore, the material dividing fixture 11 includes a material dividing truss 111, a material dividing slide 112 and a material dividing jaw 113. The material dividing truss 111 is extended in the horizontal direction, the material dividing slide 112 is extended in the vertical direction, the material dividing jaw 113 is slidably set on the material dividing slide 112, the material dividing slide 112 is slidably set on the material dividing truss 111, the material dividing jaw 113 can move up and down in the vertical direction along the material dividing slide 112, and the material dividing slide 112 can drive the material dividing jaw 113 to move horizontally along the material dividing truss 111. The material dividing truss 111 is located above the loading conveyor line 13 and the NG conveyor line 14, so that the material dividing jaw 113 can clamp the silicon blocks on the loading conveyor line 13 and transfer the silicon blocks to the NG conveyor line 14 or to the centering platform of the stick assembly unit 1.

[0077] Further, if Figures 8 to 11As shown, the material-dividing clamp 113 includes a clamp body 114, a rotating assembly 115 and a chuck assembly 116. The chuck assembly 116 is connected to the clamp body 114 through the rotating assembly 115. The chuck assembly 116 can clamp an object. The rotating assembly 115 can rotate the chuck assembly 116, thereby changing the placement direction of the clamped object on the chuck assembly 116. The clamp body 114 is slidably connected to the material-dividing slide rail 112, and can drive the clamp body 114 and the clamped object on the clamp body 114 to slide up and down along the material-dividing slide rail 112. Specifically, the chuck assembly 116 includes a first base 117, and a centering cylinder is provided on the first base 117. A first chuck is provided at each end of the centering cylinder. The centering cylinder can drive the two first chucks to move closer to or farther from each other to clamp objects such as silicon blocks. The rotating assembly 115 includes a rotating shaft, which is connected to the clamp body 114 through a shaft sleeve. The first base 117 of the chuck assembly 116 is fixedly connected to the rotating shaft. The clamp body 114 is also provided with a driving mechanism, such as a motor, etc. The driving mechanism and the rotating shaft are connected through a belt. The driving mechanism can drive the rotating shaft to rotate through the belt, thereby rotating the first base 117 and the first chuck on the first base 117, thereby changing the placement position of the clamped object on the first chuck. Preferably, the chuck assembly 116 is provided with Figure 8 The first clamping position shown and Figure 9 As shown in the second clamping position, a 90-degree angle is formed between the first clamping position and the second clamping position, the first clamping position is arranged in the horizontal direction, and the second clamping position is arranged in the vertical direction. The rotating assembly 115 can drive the clamping head assembly 116 to rotate to switch between the first clamping position and the second clamping position.

[0078] The reason why the clamping head assembly 116 in the material dividing clamping jaw 113 is set to be rotatable is that the stick assembly unit 1 and the stick assembly and stick bonding system in this scheme are particularly suitable for small silicon blocks processed from scraps such as edge skins, head and tail materials, such as Figure 46 As shown in the figure, this type of silicon block is usually thin and long, so during the loading process, Figure 12 It is more stable to transport the silicon block in the flat position shown in the figure. However, when assembling the silicon block, in order to meet the requirements of the slicing process, the silicon block needs to be placed as shown in the figure. Figure 47 In this solution, the silicon blocks are placed flat on the feeding conveyor line 13 for transportation and thickness detection, as shown in FIG. Figure 8 As shown, the material separation clamp 113 clamps the flat silicon block. If the thickness of the silicon block does not meet the preset error range, the material separation clamp 113 directly moves to the NG conveyor line 14 and puts the silicon block down. If the thickness of the silicon block meets the preset error range, Figure 9As shown in the figure, the rotating component 115 in the material separating jaw 113 drives the chuck component 116 to rotate 90 degrees, changing the silicon block from the horizontal position to the vertical position, and transporting the vertically placed silicon block to the centering platform of the rod splicing unit 1 for subsequent rod splicing and sticking operations.

[0079] Further, as Figures 12 to 17 shown, the detection component 12 is arranged close to the feeding conveyor line 13, including a first detection piece 121 and a second detection piece 122. The first detection piece 121 is located above the feeding conveyor line 13, and the second detection piece 122 is located below the feeding conveyor line 13. The positions of the first detection piece 121 and the second detection piece 122 correspond to each other in the vertical direction. A detection gap 123 is provided on the feeding conveyor line 13, and the positions of the first detection piece 121 and the second detection piece 122 correspond to the detection gap 123. When there is no silicon block placed on the conveyor belt, the first detection piece 121 and the second detection piece 122 are opposite to each other through the detection gap 123, and the distance between the two can be measured. When the silicon block is placed on the feeding conveyor line 13 for transportation, the silicon block moves to the position where the detection component 12 is located and blocks the detection gap 123. The second detection piece 122 identifies the distance between the lower surface of the silicon block and the second detection piece 122 through the detection gap 123 from below the feeding conveyor line 13. At the same time, the first detection piece 121 identifies the distance between the upper surface of the silicon block and the first detection piece 121 from above the feeding conveyor line 13. The distance between the first detection piece 121 and the second detection piece 122 is h, the distance between the first detection piece 121 and the upper surface of the silicon block is h1, and the distance between the second detection piece 122 and the lower surface of the silicon block is h2. Then, the actual thickness H of the silicon block can be calculated through the data measured by the detection component 12, H = h - h1 - h2. The first detection piece 121 and the second detection piece 122 are preferably laser sensors.

[0080] Specifically, as Figure 12 and Figure 15 shown, the feeding conveyor line 13 includes a feeding table 131. Two groups of conveyor belts arranged side by side and moving synchronously are provided on the feeding table 131, and a detection gap 123 is formed between the two groups of conveyor belts. Two groups of feeding rollers 132 are also provided on the feeding table 131. The two groups of feeding rollers 132 are respectively arranged on both sides of the feeding table 131, at the outer edges of the two groups of conveyor belts. The distance between the two groups of feeding rollers 132 is roughly matched with the width of the silicon block. The two groups of rollers extend towards the outside of the conveyor belt at the feeding end of the conveyor belt, forming a flared structure. When the silicon block starts to be transported from the feeding end of the conveyor belt, the two sides of the silicon block can be in sliding contact with the feeding rollers 132 on both sides of the conveyor belt during the movement of the conveyor belt. The two groups of rollers can adjust and limit the position of the silicon block on the conveyor belt, so that the silicon block is located in the middle position between the two groups of conveyor belts, avoiding the silicon block from being placed obliquely or offset in position. The flared structure at the ends of the two groups of rollers is more convenient for the silicon block to enter the feeding conveyor line 13.

[0081] During the transportation of the silicon blocks on the loading conveyor line 13, the thickness of the silicon blocks is detected by the detection component 12, and then they continue to move to the material distribution fixture 11 for material distribution and clamping. To prevent the silicon blocks from continuously moving out of the clamping position on the loading conveyor line 13, as Figure 15 shown, a limit stop 133 is also provided at the end of the conveyor belt. The limit stop 133 is erected above the two groups of conveyor belts and can block the continuous movement of the silicon blocks on the conveyor belt.

[0082] Furthermore, since the first detection piece 121 and the second detection piece 122 in the detection component 12 need to cooperate with each other to complete the detection of the thickness of the silicon blocks, the accuracy requirements for their relative positions are relatively high. For the convenience of adjustment, the first detection piece 121 and / or the second detection piece 122 are arranged in a movable manner to facilitate the adjustment of the relative positions between the first detection piece 121 and the second detection piece 122.

[0083] Specifically, as Figure 13 and Figure 17 shown, the detection component 12 further includes a first bracket 125 and a second bracket 124. The first detection piece 121 is arranged on the first bracket 125, and the second detection piece 122 is arranged on the second bracket 124. The first bracket 125 and the second bracket 124 are in an L shape. One end of the first bracket 125 is connected to the loading table 131 of the loading conveyor line 13, and the other end extends from above the loading conveyor line 13 towards the detection gap 123 between the two groups of conveyor belts. One end of the second bracket 124 is connected to the loading table 131 of the loading conveyor line 13, and the other end extends from below the loading conveyor line 13 towards the detection gap 123 between the two groups of conveyor belts, so that the first detection piece 121 and the second detection piece 122 are respectively arranged above and below the loading conveyor line 13.

[0084] Preferably, the second support 124 is fixedly arranged on the loading table 131, and the second detecting member 122 is fixedly arranged on the second support 124 so that the second detecting member 122 is at a fixed reference position; the first support 125 includes a first connecting rod and a second connecting rod. The first connecting rod is movably connected to the loading table 131 and can move along the material transportation direction of the loading conveyor line 13 to adjust the connection position. The second connecting rod is arranged perpendicular to the material transportation direction. One end of the second connecting rod is connected to the first connecting rod, and the other end is connected to the first detecting member 121. The first detecting member 121 is movably arranged on the second connecting rod and can move along the second connecting rod to adjust the position. The first detecting member 121 can freely adjust its position through the first connecting rod and the second connecting rod, so that the first detecting member 121 and the second detecting member 122 have a relative position suitable for detection, realizing precise control of position and accuracy, and accurately detecting whether the thickness of the silicon block is qualified. Setting the first detecting member 121 located above in a form that can be movably adjusted is more convenient for the operation of position adjustment. Of course, the second detecting member 122 can also be set in a form that can be movably adjusted, and the first detecting member 121 can be set as the positioning reference position.

[0085] The detecting assembly 12 arranged on the loading conveyor line 13 will automatically detect the thickness of the silicon block moving on the loading conveyor line 13 to detect whether the thickness of the silicon block is within the error range. When the silicon block reaches the detection position of the detecting assembly 12, the laser sensor will automatically calculate the thickness dimension of the silicon block, compare the detected thickness dimension of the silicon block with the required dimension, and if it is within the required dimension range, it meets the requirements. The silicon block that meets the requirements will be clamped by the material sorting fixture 11 and transported to the centering platform, and the silicon block that does not meet the requirements will be clamped by the material sorting fixture 11 and transported to the NG conveyor line 14.

[0086] In the above-mentioned material sorting mechanism of the rod splicing and sticking system, by reasonably setting the structure and cooperation mode of the material sorting fixture, the detecting assembly and the loading conveyor line, the material sorting mechanism can automatically complete the feeding, detection and classified transfer of materials, with a high degree of automation, improving the working efficiency of the equipment and reducing the labor cost. By setting the detecting assembly in a form that can be adjusted in position, it is convenient to calibrate and debug the detecting assembly, improving the accuracy of material detection. The material sorting fixture is arranged in a rotatable manner, improving the flexibility of the material sorting mechanism, and can automatically adjust the position of the material, facilitating subsequent operations such as discharging and splicing and sticking of the material.

[0087] Further, as Figure 18 and Figure 19 shown, one end of the centering platform is arranged close to the material sorting mechanism, and the other end is arranged close to the rod arranging assembly. The centering platform can receive the silicon block with qualified detection transmitted from the material sorting mechanism, adjust the position of the silicon block, and transmit the silicon block with adjusted position to the rod arranging assembly, preparing for the subsequent rod splicing and sticking process.

[0088] Specifically, the centering platform includes a platform bracket 15, on which two groups of moving sliders 16 are arranged. The moving sliders 16 can reciprocally slide on the platform bracket 15 under the drive of a drive assembly. As Figure 20 and Figure 21 shown, the moving slider 16 includes a slider base 161, on which three groups of centering jaws 162 are arranged side by side. The distance between adjacent two groups of centering jaws 162 is equal. One detection device 163 is arranged on each group of centering jaws 162. The detection device 163 is preferably a sensor. The feeding fixture 11 in the material distribution mechanism places the silicon blocks that pass the inspection vertically at any one of the centering jaws 162 of the moving slider 16. When the detection device 163 on the centering jaws 162 detects a silicon block, the centering jaws 162 start to work. The two chucks on the centering jaws 162 respectively push and squeeze the silicon block from both sides of the silicon block to achieve the centering operation of the silicon block position; the feeding fixture 11 starts to place the silicon blocks at the first group of centering jaws 162 and ends until silicon blocks are placed on all three groups of centering jaws 162. As Figure 18 and Figure 19 shown, the two groups of moving sliders 16 on the platform bracket 15 are transported in parallel. When the positions of the silicon blocks on the three groups of centering jaws 162 of the first moving slider 16 are adjusted, the first moving slider 16 slides towards the rod arranging assembly and waits for the rod arranging assembly to clamp the silicon blocks. At this time, the second moving slider 16 can synchronously perform the centering adjustment of the silicon blocks. After all the silicon blocks on the second moving slider 16 complete the position adjustment, the second moving slider 16 slides towards the rod arranging assembly, and the first moving slider 16 returns. The two groups of moving sliders 16 can move independently of each other without interference. The setting method of alternately transporting the two groups of moving sliders 16 and multi-station centering adjustment of the positions of the three groups of centering jaws 162 greatly improves the working efficiency of the centering platform.

[0089] During the process of transferring the silicon rod from the material distribution mechanism to the centering platform, the feeding fixture 11 places the silicon block at the middle position of the centering jaws 162, and the two chucks of the centering jaws 162 clamp the silicon block from both sides. It can be understood that if the clamped surface of the silicon block is parallel to the clamping surface of the centering jaws 162, the centering jaws 162 can completely fit with the clamped surface of the silicon block and push the silicon block when moving. However, if there is an angular deviation between the feeding fixture 11 and the centering jaws 162, making the clamped surface of the silicon block non-parallel to the clamping surface of the centering jaws 162 and having a large angular deviation, the centering jaws 162 will push the silicon block crooked during the moving process and then clamp it, which will cause the silicon block to be misaligned during the transfer process.

[0090] To solve the above problems, as Figure 21As shown in the figure, the centering jaw 162 is arranged on the adjustment plate 164. The adjustment plate 164 is rotatably adjusted and arranged on the sliding table base 161. By adjusting the installation angle of the adjustment plate 164 on the sliding table base 161, the clamping position of the centering jaw 162 can be made to be parallel to the delivery position where the silicon block is transferred by the splicing bar fixture, thereby avoiding misalignment of the silicon block during centering adjustment. Specifically, an arc-shaped connection hole 165 is provided on the adjustment plate 164, and a pin is arranged in the connection hole 165. The adjustment plate 164 is connected to the sliding table base 161 through the cooperation of the pin and the connection hole 165, and the fixed connection position between the connection hole 165 and the pin can be adjusted. Since the connection hole 165 is arc-shaped, the adjustment plate 164 can rotate within a certain angle range to finely adjust the installation angle of the adjustment plate 164. Preferably, two connection holes 165 are provided on the adjustment plate 164, symmetrically arranged at both ends of the adjustment plate 164, and two pins are arranged in each connection hole 165. This setting method is not only convenient for angle adjustment but also can ensure the stability of the installation of the adjustment plate 164.

[0091] Specifically, as Figure 19 shown in the figure, two groups of linear guide rails are arranged side by side on the platform bracket 15. Sliders are arranged below the sliding table base 161 of the moving sliding table 16, and the sliders are slidably connected to the linear guide rails so that the sliding table base 161 is slidably arranged on the platform bracket 15. A conveyor belt is also arranged on the linear guide rails. As Figure 20 shown in the figure, conveyor belt clamping members 166 are correspondingly arranged on the sliding table base 161. There are two groups of clamping members 166, respectively located at both ends of the sliding table base 161. The clamping members 166 can clamp the conveyor belt on the linear guide rails. The conveyor belt can move along the extension direction of the linear guide rails under the drive of the drive assembly, thereby driving the moving sliding table 16 to reciprocate along the linear guide rails. The clamping member 166 includes a fixing plate fixedly connected to the sliding table base 161 and an adjusting plate movably connected to the fixing plate. A clamping space for clamping the conveyor belt is formed between the adjusting plate and the fixing plate. By adjusting the distance between the adjusting plate and the fixing plate, the clamping strength of the clamping member 166 for the conveyor belt can be adjusted.

[0092] Preferably, each group of linear guide rails includes two parallel tracks. Two groups of sliders are correspondingly arranged on the sliding table base 161. The conveyor belt on the linear guide rails is located above the two tracks and is arranged at the middle position corresponding to the two tracks. The clamping member 166 is arranged at the middle position of the end of the sliding table base 161. Adopting this setting method is beneficial to improving the stability of the moving sliding table 16 during the sliding process.

[0093] Preferably, the widths of the adjusting plate and the fixing plate are greater than the width of the conveyor belt on the linear guide rails. Anti-slip patterns are provided on the clamping surfaces of the adjusting plate and / or the fixing plate, thereby improving the clamping strength of the clamping member 166.

[0094] Preferably, the centering jaws 162 on the two groups of moving slides 16 are arranged opposite to each other, that is, the centering jaws 162 on the first moving slide 16 are arranged towards the direction where the second moving slide 16 is located, and the centering jaws 162 on the second moving slide 16 are arranged towards the direction where the first moving slide 16 is located. By adopting this setting method, the centering workstations on the two groups of moving slides 16 can be closer to each other at the material distribution mechanism or the rod arranging assembly, thereby reducing the distance that the material distribution mechanism and the rod arranging assembly need to move when transferring the silicon rods on the centering platform, and further improving the work efficiency.

[0095] In the specific implementation manner of the above-mentioned centering platform, setting the centering platform as two groups of moving slides 16, with each group of moving slides 16 configured with three groups of centering jaws 162 is a preferred implementation manner. Adopting this setting method can ensure that the equipment has a smaller volume and occupied space while improving the work efficiency of the equipment, and at the same time form an efficiency cooperation with the upstream material distribution mechanism and the downstream rod arranging assembly. Of course, according to actual production requirements, three or more moving slides 16 can also be arranged on the platform support 15, and two groups or more than three groups of centering jaws 162 can also be arranged on each moving slide 16 to improve production efficiency.

[0096] The centering platform in the above-mentioned rod splicing and sticking system improves the transfer efficiency by alternately reciprocating sliding of the double moving slides, better quickly connecting the upstream and downstream processes. The setting of multiple centering workstations can also adjust the positions of multiple clamped objects at the same time, further improving the work efficiency of the centering platform. The centering jaws can be rotatably adjusted through the adjustment plate, which is convenient for adjusting the clamping angle of the centering jaws and is beneficial to improving the accuracy of the position adjustment of the clamped object. The moving connection structure of the slide base on the platform support can make the operation of the moving slide more stable and smooth on the basis of ensuring the work efficiency.

[0097] Further, as Figure 22 shown, the rod arranging assembly includes a rod splicing fixture 17 and a rod splicing table 18. As Figure 26 shown, multiple silicon blocks are placed side by side on the rod splicing table 18. The spacing between these silicon blocks is certain and very small. The function of the rod splicing fixture 17 is to clamp a group of silicon blocks whose positions are initially adjusted on the centering platform, further reduce the spacing between adjacent silicon blocks, and then arrange this group of silicon blocks on the rod splicing table 18 until a whole rod is arranged (the whole rod can be approximately composed of 20 to 30 silicon blocks).

[0098] Specifically, the stick splicing fixture 17 includes a stick splicing truss 171, a stick splicing slide rail 172, and a stick splicing jaw 173. The stick splicing truss 171 extends horizontally, the stick splicing slide rail 172 extends vertically, the stick splicing jaw 173 is slidably arranged on the stick splicing slide rail 172, and the stick splicing slide rail 172 is slidably arranged on the stick splicing truss 171. The stick splicing jaw 173 can move up and down in the vertical direction along the stick splicing slide rail 172, and the stick splicing slide rail 172 can drive the stick splicing jaw 173 to move horizontally along the stick splicing truss 171. The stick splicing truss 171 is located above the stick splicing table 18 and the centering platform, so that the stick splicing jaw 173 on the stick splicing fixture 17 can pick up the silicon blocks on the centering platform, adjust the positions between the silicon blocks to keep a certain distance between adjacent silicon blocks, and then transfer and place them on the stick splicing table 18. The stick splicing fixture 17 repeats the placing action until a complete stick is formed.

[0099] The stick splicing jaw 173 in the stick splicing fixture 17 includes a second base 174. A fixed chuck and a movable chuck for clamping the object to be clamped are arranged on the second base 174. The fixed chuck is fixedly connected to the second base, and there are two groups of movable chucks. The two groups of movable chucks are respectively arranged on both sides of the fixed chuck, and the two groups of movable chucks can slide on the second base 174 and move towards the fixed chuck from both sides of the fixed chuck to reduce the distance between the objects to be clamped.

[0100] Specifically, as Figures 23 to 25 shown, a second chuck 175 and two third chucks 176 are arranged on the second base 174. The second chuck 175 is fixedly connected to the second base 174 and is located in the middle of the second base 174. The two third chucks 176 are respectively arranged on both sides of the second chuck 175. A stick splicing guide rail is also arranged on the second base 174. The two third chucks 176 are movably connected to the stick splicing guide rail, and the third chucks 176 can slide along the stick splicing guide rail to approach or move away from the second chuck 175. Of course, the third chuck 176 can also be slidably connected to the second base 174 by other common sliding structures.

[0101] Preferably, the two third chucks 176 form a set of centering jaws 162 and are driven by a servo centering drive mechanism. The two third chucks 176 synchronously approach or move away from the second chuck 175 in a centering manner with the second chuck 175 as the center. The servo centering drive mechanism can accurately control and position the center positions of the two third chucks 176 relative to the second chuck 175, so as to accurately control the relative positions of the silicon block on the second chuck 175 and the two silicon blocks on the third chucks 176.

[0102] Preferably, as Figure 23 and Figure 24As shown, the second chuck 175 includes a first driving part and two first clamping parts which are connected to each other. The first driving part can drive the two first clamping parts to approach or move away from each other, so as to clamp or place the silicon block. The third chuck 176 includes a second driving part and two second clamping parts which are connected to each other. The second driving part can drive the two second clamping parts to approach or move away from each other, so as to clamp or place the silicon block. An extension part 177 is arranged on the second clamping part of the third chuck 176. The extension part 177 extends towards the position where the first clamping part of the second chuck 175 is located, so that the second clamping part can be closer to the first clamping part in the sliding direction of the third chuck 176. The second clamping parts on the two third chucks 176 located on both sides of the second chuck 175 are preferably arranged in this way, that is, the extension parts 177 on the two second clamping parts extend towards the first clamping part relatively from both sides of the second chuck 175. By adopting the above arrangement, it is beneficial to adjust the small distance between adjacent silicon blocks on the stick assembling jaw 173. At the same time, the driving parts between the adjacent second chuck 175 and third chuck 176 will not interfere with each other during the movement process, which is more beneficial to the position arrangement of the silicon blocks.

[0103] The stick assembling jaw 173 is preferably as described above, including a second chuck 175 fixedly arranged at the middle position and two third chucks 176 moving in a centered manner on both sides, which can clamp three silicon blocks on the centering platform at the same time. This arrangement can not only improve the working efficiency of the silicon block stick assembling, but also be beneficial to accurately control the distance between adjacent silicon blocks, and is more convenient to adjust the distance between adjacent silicon blocks. Of course, in addition to the above preferred arrangement, the second jaws and third jaws on the stick assembling jaw 173 can also be arranged in a movable form, and the number of jaws for clamping the silicon blocks can also be set to two or more than three.

[0104] Furthermore, detection devices are arranged on both the second chuck 175 and the third chuck 176. The detection devices are preferably sensors. When the stick assembling jaw 173 in the stick assembling fixture 17 moves to the centering platform, if the detection devices on the second chuck 175 and the third chuck 176 detect the silicon block, the jaws start to work, and the first clamping part and the second clamping part clamp the silicon block from the two narrow sides of the silicon block, realizing the clamping operation of the silicon block.

[0105] Specifically, such as Figures 26 to 28As shown in the figure, the stick-assembling table 18 includes a support frame 181. A stick-assembling substrate 182 for placing silicon blocks is provided on the support frame 181. A buffer pad 183 is provided on the stick-assembling substrate 182. The buffer pad 183 is preferably a nylon buffer pad. The buffer pad 183 can avoid bumping the silicon blocks and damaging them while ensuring the surface accuracy. A fixing device is also provided on the stick-assembling substrate 182. The fixing device can position and fix each silicon block placed on the stick-assembling substrate 182, keep the position of the silicon block unchanged, and prevent the silicon block from shaking or tilting and collapsing.

[0106] The fixing device is preferably an adsorption device 184, which includes a plurality of vacuum suction cups and a suction cup fixing plate for fixing the vacuum suction cups. When the stick-assembling jaws 173 transport the silicon blocks from the centering platform to the stick-assembling table 18, the plurality of vacuum suction cups in the adsorption device 184 can respectively adsorb the bottoms of the plurality of silicon blocks, so as to position and fix the silicon blocks. After the vacuum suction cups complete the adsorption, the stick-assembling jaws 173 release the silicon blocks and perform the next round of clamping. After the stick-assembling of the silicon block group on the stick-assembling table 18 is completed, it waits for the glue clamping fixture in the curing unit 3 to clamp it to the curing unit 3 for bonding and curing.

[0107] Specifically, the buffer pad 183 is arranged in the middle of the stick-assembling substrate 182. A long strip-shaped hollow structure is arranged in the middle part of the buffer pad 183. The plurality of vacuum suction cups are arranged side by side in the hollow structure of the buffer pad 183. The adsorption surface of the vacuum suction cup is substantially flush with the upper surface of the buffer pad 183. When the silicon block is moved to the stick-assembling table 18, the two ends of the lower surface of the silicon block can contact the buffer pad 183 to ensure that the silicon block is placed stably. The middle part of the lower surface of the silicon block can be adsorbed and fixed by the vacuum suction cup to prevent the silicon block from shifting or toppling.

[0108] The above-mentioned fixing device can also be a plurality of fixed partitions arranged side by side and at intervals. The silicon blocks are placed in the intervals between adjacent fixed partitions, and the positioning and discharging are realized through the fixed partitions to prevent toppling.

[0109] Furthermore, a quantity detection device 185 is also provided on the stick-assembling table 18. The quantity detection device 185 is used to detect the quantity of the silicon blocks discharged on the stick-assembling table 18. When the quantity of the silicon blocks reaches the quantity requirement of a whole stick, the glue clamping fixture in the curing unit 3 can clamp and transfer the silicon block group. Preferably, the quantity detection component 12 includes a mounting frame 186. One end of the mounting frame 186 is connected to the support frame 181, and the other end extends in a direction away from the support frame 181. The sensor for detecting the quantity is arranged at the end of the mounting frame 186 away from the support frame 181, so as to form a spaced space between the sensor and the support frame 181. The spaced space can prevent the stick-assembling jaws 173 or the stick-gluing fixture from interfering with the sensor when placing or clamping the silicon blocks.

[0110] In the rod arranging component of the above-mentioned rod splicing and sticking system, two groups of moving chucks are based on the fixed chuck in the middle and adjust their positions in a centered manner, which is beneficial to improving the adjustment accuracy of the distance between the clamped objects and enabling precise control of the relative positions of the clamped objects. The specific structural design of the chuck is beneficial to the adjustment of the tiny distance between adjacent clamped objects, and at the same time, there will be no mutual interference between adjacent chucks during the movement process, which is more conducive to the position arrangement of the clamped objects. The fixing device on the rod splicing table can position and fix the material blocks placed on the rod splicing substrate, making the positions of the material blocks fixed and unchanged, and at the same time preventing the material blocks from shaking or tilting and collapsing. There is a spaced space formed between the quantity detection device on the rod splicing table and the rod splicing table, which can avoid position interference between the material block fixture when placing or picking up the material block and the detection device.

[0111] Further, as Figure 1 and Figure 2 shown, the glue coating unit 2 includes a workpiece plate conveying line and a glue coating device. The workpiece plate conveying line is used to transport the workpiece plate, and the glue coating device can automatically perform glue coating operations on the workpiece plates placed on the workpiece plate conveying line. The glue sticking fixture in the curing unit 3 can clamp the glue-coated workpiece plates to the curing table in the curing unit 3, and then clamp the arranged silicon block groups and place them on the workpiece plates, so as to bond and cure the workpiece plates and the silicon block groups to form silicon block rods convenient for subsequent slicing processing.

[0112] Further, as Figure 29 and Figure 30 shown, the curing unit 3 is arranged on one side of the glue coating unit 2 and includes a curing table 31, a glue sticking fixture 32 and a curing fixture 33. The glue sticking fixture 32 can move to the glue coating unit 2 to clamp the glue-coated workpiece plates, place the workpiece plates on the curing table 31, and then move to the rod splicing table 18 in the rod splicing unit 1 to grab an arranged group of silicon block groups, and place the silicon block groups on the glue-coated workpiece plates on the curing table 31, so as to bond the silicon block groups and the workpiece plates. The glue sticking fixture 32 clamps the upper part of the silicon block group. When the glue sticking fixture 32 places the silicon block group, the curing fixture 33 arranged on the curing table 31 first clamps the lower side of the silicon block group. After the curing fixture 33 clamps the silicon block group, the glue sticking fixture 32 then releases the silicon block group. This operation is to avoid the problem that when the rod sticking fixture releases the silicon block group, each silicon block shifts or topples on the workpiece plate. The curing fixture 33 can continuously clamp the silicon block during the bonding and curing process of the silicon block group and the workpiece plate, ensuring that each silicon block combines with the workpiece plate at the preset position, and finally obtaining silicon block rods that meet the requirements.

[0113] Specifically, as Figure 33As shown in the figure, the curing table 31 includes a support base 311. A curing position and a pressure-holding block placement table are provided on the support base 311. The curing fixture 33 is arranged at the curing position, and a pressure-holding block 312 is placed on the pressure-holding block placement table. After the curing fixture 33 clamps the silicon block group, the glue-bonding fixture 32 releases the silicon block, then clamps the pressure-holding block 312 from the pressure-holding block placement table, places it on the upper part of the silicon block group to press the silicon block, and under the cooperation of the gravity of the pressure-holding block 312, enables the silicon block to be in full contact with the glue on the workpiece plate, completing the bonding and curing operation. Positioning pins that cooperate with the workpiece plate are also provided on the curing table 31 for positioning the workpiece plate when the workpiece plate is placed. Two or more curing positions are provided on the support base 311 to facilitate the bonding and curing of multiple groups of silicon block rods simultaneously, improving work efficiency.

[0114] As Figure 29 and Figure 30 shown in the figure, the glue-bonding fixture 32 includes a glue-bonding truss 321, a glue-bonding slide rail 322, and glue-bonding jaws 323. The glue-bonding truss 321 extends horizontally, the glue-bonding slide rail 322 extends vertically, the glue-bonding jaws 323 are slidably arranged on the glue-bonding slide rail 322, the glue-bonding slide rail 322 is slidably arranged on the glue-bonding truss 321, the glue-bonding jaws 323 can move up and down in the vertical direction along the glue-bonding slide rail 322, and the glue-bonding slide rail 322 can drive the glue-bonding jaws 323 to move horizontally along the glue-bonding truss 321 together. The glue-bonding truss 321 is located above the curing table 31 and the rod-assembling table 18 to facilitate the glue-bonding jaws 323 on the glue-bonding fixture 32 to pick up the silicon block group on the rod-assembling table 18 and place it on the curing table 31, or pick up the pressure-holding block 312 on the curing table 31 for pressure-holding operation, or remove the silicon block rod that has completed bonding and curing on the curing table 31.

[0115] Specifically, as Figure 31 , Figures 34 to 40 shown in the figure, the glue-bonding fixture can be used to pick up more than two different objects. The glue-bonding jaws 323 in the glue-bonding fixture 32 include a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is driven by a first driving member and can be opened or tightened along a first direction to clamp an object, forming a first clamping space for clamping the object; the second clamping mechanism is driven by a second driving member and can be opened or tightened along a second direction to clamp an object, forming a second clamping space for clamping the object. The first direction and the second direction are different directions. Preferably, the first direction and the second direction are perpendicular to each other in the horizontal direction. The first clamping space and the second clamping space are overlapped, and the first clamping mechanism and the second clamping mechanism can clamp different objects to be clamped.

[0116] Due to different clamping directions and specific clamping structures, the first clamping mechanism and the second clamping mechanism can be used to clamp two or more different objects. In this embodiment, the first clamping mechanism is used to clamp a plurality of silicon blocks arranged side by side, and the second clamping mechanism is used to clamp a workpiece plate, a pressure-holding block 312, and a silicon block rod formed by bonding and curing the workpiece plate and a plurality of silicon blocks. The first clamping space and the second clamping space are overlapped, so that while the glue clamping jaw 323 can clamp a variety of objects, the clamping space on the glue clamping jaw 323 is fully utilized, reducing the volume and occupied space of the glue clamping jaw 323 on the basis of increasing the grasping function of the glue clamping jaw 323.

[0117] Furthermore, the first clamping mechanism is used to clamp a plurality of silicon blocks simultaneously, and there are certain differences in the sizes of the plurality of silicon blocks. In order to ensure that all the silicon blocks can be stably clamped without being damaged, the first clamping mechanism includes a first fixed clamping part 324 and a plurality of first elastic clamping parts 325. The first fixed clamping part 324 and the plurality of first elastic clamping parts 325 are arranged opposite to each other in position, and each silicon block corresponds to a first elastic clamping part 325. A positioning reference surface is provided on the first fixed clamping part 324. The first elastic clamping part 325 is elastically clamped. Under the drive of the first driving member, the first fixed clamping part 324 and the first elastic clamping part 325 can move relative to each other. One side surface of the silicon block abuts against the positioning reference surface of the first fixed clamping part 324 to realize the positioning of the relative positions of the plurality of silicon blocks, and the other side surface of the silicon block abuts against the first elastic clamping part 325. Since the first elastic clamping part 325 is elastically clamped, each first elastic clamping part 325 will appropriately apply a clamping force according to the actual size of its corresponding silicon block to ensure that the plurality of silicon blocks are stably clamped simultaneously without being damaged.

[0118] Specifically, as Figure 31 and Figure 35 shown, the first fixed clamping part 324 includes a strip-shaped first cushion block, and the clamping surface of the first cushion block is a plane, and this plane can form a positioning reference surface. The first clamping mechanism further includes a clamping substrate 326. The clamping substrate 326 and the first fixed clamping part 324 are arranged opposite to each other in position. The first elastic clamping part 325 includes a second cushion block 327 and a spring. One end of the spring is connected to the clamping substrate 326, and the other end is connected to the second cushion block 327. The springs and the second cushion blocks 327 of the plurality of first elastic clamping parts 325 are arranged side by side on the clamping substrate 326. When the first clamping mechanism clamps the silicon block group, the spring in the first elastic clamping part 325 can provide elastic buffering when the second cushion block 327 presses the side wall of the silicon block, and provide corresponding pressing force compensation for different size situations of different silicon blocks.

[0119] Preferably, as Figure 31As shown, each first elastic clamping portion 325 includes two sets of springs, which are arranged vertically one above the other to be respectively connected to the upper end portion and the lower end portion of the second cushion block 327. This setting method is conducive to improving the pressing force compensation effect and has better clamping stability.

[0120] Preferably, the first cushion block and the second cushion block 327 are nylon cushion blocks.

[0121] In addition to the above preferred setting method, the springs in the first elastic clamping portion 325 can also be replaced with elastic metal shrapnel, or the springs and the second cushion block 327 can be replaced with silica gel cushion blocks that can provide elastic clamping, etc.

[0122] Specifically, as Figure 34 shown, the second clamping mechanism in the adhesive gripper 323 includes two fourth jaws 328 arranged oppositely, and the second driving member can drive the two fourth jaws 328 to move relatively to achieve the clamping action. The two fourth jaws 328 are respectively arranged at two end positions of the first clamping mechanism, that is, the two fourth jaws 328 are respectively arranged facing the silicon blocks at both ends in the silicon block group on the first clamping mechanism. As Figure 39 shown, the extension length of the lower end of the fourth jaw 328 exceeds the extension length of the lower end of the first clamping mechanism. Adopting this setting method can increase the clamping range of the second clamping mechanism, facilitate clamping of various objects such as a workpiece plate and a pressure-holding block 312, and avoid movement interference with the first clamping mechanism.

[0123] Preferably, a convex structure 329 is further arranged on the inner side surface of the lower end of the fourth jaw 328. The middle part of the convex structure 329 is concave and the two ends are convex to form a clamping card slot. When the fourth jaw 328 clamps the workpiece plate and the pressure-holding plate, the object to be clamped can be clamped in the clamping card slot, thereby improving the clamping stability and avoiding loosening of the object to be clamped and causing processing accidents.

[0124] In the above adhesive gripper 323, the first driving member and the second driving member can adopt a cylinder guide rod mechanism, that is, a driving system composed of a gear linkage assembly, a connecting rod and a cylinder; or, a servo centering driving mechanism, that is, a driving system composed of a servo motor, a reducer and a ball screw.

[0125] The glue clamping fixture 32 in the above-mentioned stick splicing and gluing system is a composite manipulator. By simultaneously setting the first clamping mechanism and the second clamping mechanism, the technical effect of separately picking and placing multiple silicon blocks, workpiece plates, pressure-holding blocks 312, and the silicon block rods after bonding and curing is achieved. The two types of jaws are combined, enabling the glue clamping fixture to be used for picking up more than two different objects. Moreover, the two types of jaws share a clamping space, greatly reducing the volume and occupied space of the glue clamping fixture, and making it more convenient to move in the stick splicing and gluing system. The fixed clamping part and the elastic clamping part are cooperatively arranged to ensure that when picking up multiple material blocks simultaneously, the clamping position can be accurately positioned, and the size deviation between the material blocks can be adapted, providing a pressing force compensation to ensure the stability of clamping without damaging the material blocks.

[0126] Furthermore, the curing fixture 33 in the curing unit 3 is arranged on the curing table 31, and a curing fixture 33 is correspondingly arranged at each curing position on the curing table 31. The curing fixture 33 is used to dock with the stick gluing fixture, receive multiple silicon blocks to be spliced and bonded from the glue clamping fixture 32, and ensure that the multiple silicon blocks do not shift or topple during the transfer process. The curing fixture 33 continuously clamps the silicon blocks during the bonding and curing process of the multiple silicon blocks and the workpiece plate until the curing is completed.

[0127] Similar to the glue clamping fixture 32, the curing fixture 33 also needs to clamp multiple silicon blocks simultaneously. Since there are certain differences in the sizes of the multiple silicon blocks, in order to ensure that all the multiple silicon blocks can be stably clamped without being damaged, as Figures 41 to 44 shown, the curing fixture 33 includes a second fixed clamping part 331 and multiple second elastic clamping parts 332. The second fixed clamping part 331 and the multiple second elastic clamping parts 332 are arranged opposite to each other in position, and each silicon block corresponds to a second elastic clamping part 332. A positioning reference surface is provided on the second fixed clamping part 331, the second elastic clamping part 332 is elastically clamped, and the second fixed clamping part 331 and the second elastic clamping part 332 can move relatively to clamp the silicon block. One side of the silicon block abuts against the positioning reference surface of the second fixed clamping part 331 to achieve the positioning of the relative positions of the multiple silicon blocks, and the other side of the silicon block abuts against the second elastic clamping part 332. Since the second elastic clamping part 332 is elastically clamped, each second elastic clamping part 332 will appropriately apply a clamping force according to the actual size of the corresponding silicon block to ensure that the multiple silicon blocks are stably clamped simultaneously without being damaged.

[0128] Furthermore, as Figure 41As shown, a curing platform is provided between the second fixed clamping portion 331 and the plurality of second elastic clamping portions 332. The workpiece plate coated with the adhesive is placed on the curing platform, and the silicon block group is placed on the workpiece plate. Since the adhesive usually has a certain fluidity, the thickness of the adhesive on the workpiece plate may be uneven. In order to enable each silicon block in the silicon block group to fully and closely contact and bond with the workpiece plate and the adhesive, it is necessary to push and extrude the silicon block downward from the top of the silicon block, for example, using a pressure plate to press the silicon block. Based on this, the second fixed clamping portion 331 and the second elastic clamping portion 332 move relative to each other in the horizontal direction to clamp the silicon block. The second fixed clamping portion 331 and the second elastic clamping portion 332 are arranged to roll and clamp in the vertical direction. When the self-gravity of the silicon block, the pressure of the pressure block 312 or other forces act on the silicon block, the silicon block can move slightly downward in the vertical direction while ensuring that its position remains relatively stationary in the horizontal direction, so as to enhance the close contact with the workpiece plate and the adhesive.

[0129] Specifically, as Figure 42 shown, the second clamping mechanism includes a first substrate 333 and a second substrate 334 arranged opposite to each other. The second fixed clamping portion 331 is provided on the first substrate 333, and the second elastic clamping portion 332 is provided on the second substrate 334. The second fixed clamping portion 331 includes an elongated roller 335. The roller 335 is provided on the first substrate 333, and the axis of the roller 335 extends in the transverse direction, so that the roller 335 can roll in the vertical direction. Since the position between the first substrate 333 and the roller 335 is relatively fixed, the surface of the roller 335 tangent to the silicon block can form a positioning reference surface. The second elastic clamping portion 332 includes a roller 336 and a spring. One end of the spring is connected to the second substrate 334, and the other end is connected to the roller 336. The springs and rollers 336 of the plurality of second elastic clamping portions 332 are arranged side by side on the second substrate 334. When the second clamping mechanism clamps the silicon block group, the spring in the second elastic clamping portion 332 can provide elastic buffering when the roller 336 presses the side wall of the silicon block, and provide corresponding pressing force compensation for different sizes of different silicon blocks. At the same time, the silicon block can be slightly adjusted in position in the vertical direction under the clamping of the roller 335 and the roller 336.

[0130] Preferably, as Figure 43 shown, each second elastic clamping portion 332 includes two sets of springs, and the two sets of springs are arranged vertically one above the other to be respectively connected to the upper end and the lower end of the roller 336. This setting method is beneficial to improving the pressing force compensation effect and has better clamping stability.

[0131] In addition to the above preferred setting method, the spring in the second elastic clamping portion 332 can also be replaced with an elastic metal shrapnel, or the spring and the roller 336 can be integrally replaced with a silicone roller 336 capable of providing elastic clamping, etc.

[0132] Preferably, as Figure 42 and Figure 44 shown, two or more rollers 335 are provided on the second fixed clamping portion 331, and rollers are provided at the joint portions between adjacent rollers 335. Since the length of the second fixed clamping portion 331 is relatively long, when the roller 335 is provided as a whole, the middle portion of the roller 335 is prone to deformation in the state of clamping the silicon block, resulting in insufficient clamping of the silicon block. Therefore, the roller 335 is provided as two or more, and the ends of the two or more rollers 335 are joined to form a strip-shaped roller assembly. This setting method can make the length of each individual roller 335 shorter, reduce the deformation amount, and further ensure sufficient clamping of the silicon block; in order to ensure that the joint portion between two adjacent rollers 335 does not affect the clamping effect, rollers are provided at the joint to avoid the problem of insufficient clamping force at the joint portion.

[0133] Preferably, in order to adapt to the arrangement and clamping of silicon blocks of different specifications, the second elastic clamping portion 332 is provided as a detachable and replaceable structure, and the number of rollers and the interval distance between the rollers on different second elastic clamping portions 332 are different to match silicon blocks of different specifications.

[0134] The curing fixture in the above-mentioned stick splicing and sticking system adopts the cooperation of a fixed clamping portion and an elastic clamping portion. When simultaneously clamping multiple material blocks, it can not only accurately position the clamping position, but also adapt to the dimensional deviation between the material blocks, provide pressing force compensation, ensure the stability of clamping and not damage the material blocks. The fixed clamping portion and the elastic clamping portion adopt a rolling clamping method in the vertical direction, which can ensure that the material block moves slightly downward in the vertical direction while remaining relatively stationary in the horizontal direction, so as to enhance the close contact between the material block, the workpiece plate and the adhesive.

[0135] Furthermore, as Figure 1 and Figure 2As shown in the figure, the stick assembling and gluing system further includes a truss assembly 5. The truss assembly 5 is erected above the stick assembling unit 1, the glue applying unit 2 and the curing unit 3. The truss assembly 5 extends along the extension direction of the X-axis in the horizontal direction. The stick assembling truss 171 in the stick assembling jig 17 and the glue applying truss 321 in the glue applying jig 32 are arranged on the truss assembly 5 and can reciprocate along the truss assembly 5 in the X-axis direction; the stick assembling truss 171 and the glue applying truss 321 extend along the extension direction of the Y-axis in the horizontal direction. The stick assembling slide rail 172 is arranged on the stick assembling truss 171 and can reciprocate along the stick assembling truss 171 in the Y-axis direction. The glue applying slide rail 322 is arranged on the glue applying truss 321 and can reciprocate along the glue applying truss 321 in the Y-axis direction; the stick assembling slide rail 172 and the glue applying slide rail 322 extend along the extension direction of the Z-axis in the vertical direction. The stick assembling jaw 173 is arranged on the stick assembling slide rail 172 and can reciprocate along the stick assembling slide rail 172 in the Z-axis direction. The glue applying jaw 323 is arranged on the glue applying slide rail 322 and can reciprocate along the glue applying slide rail 322 in the Z-axis direction. The X-axis, Y-axis and Z-axis directions are perpendicular to each other, so that the stick assembling jaw 173 and the glue applying jaw 323 can move independently or in parallel in three-dimensional space to flexibly grasp objects.

[0136] In the stick assembling and gluing system of this solution, by reasonably configuring the material distribution mechanism, the centering platform, the stick arranging assembly, the curing table, the glue applying jig and the curing jig, it can automatically and quickly and efficiently realize the positioning and arrangement of the silicon blocks, and avoid the position deviation or toppling of each silicon block on the workpiece plate when the glue applying jig releases the silicon block. The curing jig can continuously clamp the silicon block during the bonding and curing process of the silicon block and the workpiece plate, ensuring that each silicon block is combined with the workpiece plate at the preset position, and finally obtaining a silicon block rod that meets the requirements. In addition, the stick assembling and gluing system can automatically arrange the silicon block rods at equal intervals, making it more convenient to configure a suitable cutting wire mesh during subsequent slicing processing. The cutting wire mesh does not need to be repeatedly readjusted, which helps to further improve production efficiency and ensure slicing quality.

[0137] This solution also discloses a stick assembling and gluing method, as Figure 45 shown, which specifically includes:

[0138] 1. Load the material blocks, detect whether the material blocks are qualified, and distribute the material blocks according to the detection results.

[0139] The material blocks are loaded through the loading conveyor line. The thickness of the material blocks is detected during the loading process. The material blocks with unqualified thickness are removed and clamped by the material distribution jig and transported out of the production line through the NG conveyor line.

[0140] 2. Adjust the positions of the qualified material blocks, and transfer the material blocks with adjusted positions to the stick assembling table for discharging the material blocks for discharging.

[0141] The material blocks with qualified thickness are adjusted in position. The material blocks are clamped by the blanking fixture and rotated 90 degrees along the length direction, being adjusted from the horizontal placement position to the vertical placement position.

[0142] The material blocks adjusted to the vertical placement position are transferred by the blanking fixture to the centering platform for centering adjustment. The centering platform includes multiple centering stations, and multiple material blocks are centered and adjusted simultaneously.

[0143] The splicing bar fixture clamps multiple material blocks with good centering adjustment and adjusts the spacing between the material blocks, reducing the spacing between adjacent material blocks.

[0144] Preferably, there are at least two groups of moving sliders on the centering platform, preferably two groups. The two groups of moving sliders reciprocate alternately between the loading end where the blanking fixture is located and the bar arranging end where the splicing bar fixture is located. When the position adjustment of the material blocks on any one group of moving sliders is completed, they move from the loading end to the bar arranging end and wait to be clamped. After the material blocks are clamped, the moving sliders return to the loading end to repeat the centering adjustment operation. The two groups of moving sliders operate independently of each other and do not interfere with each other.

[0145] Preferably, each group of moving sliders includes three centering stations, and the spacing between the stations is equal; the blanking fixture places the material blocks on any one of the centering stations, and the centering station centers and clamps the material blocks. The blanking fixture releases the material blocks and repeats the next loading, blanking, and placing operations. The blanking fixture places materials on the three centering stations in sequence until materials are placed on all three centering stations and then it ends.

[0146] Preferably, the splicing bar fixture simultaneously clamps three material blocks on the moving slider, making the material blocks on both sides move synchronously towards the material block in the middle to reduce the spacing between the three material blocks.

[0147] 3. Discharge the material blocks with adjusted positions, and repeat the discharging action until the number of arranged material blocks reaches the preset requirement, forming a group of material groups to wait to be clamped for bonding and curing.

[0148] Preferably, the splicing bar fixture transports the material blocks from the moving slider to the splicing bar table for discharging materials. The adsorption device on the splicing bar table can adsorb the material blocks to prevent the material blocks from slightly shaking or tilting and collapsing.

[0149] 4. Load the workpiece plate and apply glue on the workpiece plate.

[0150] The workpiece plate is loaded through the workpiece plate conveyor line, and the automatic glue application device on one side of the workpiece plate conveyor line applies glue on the bonding surface of the material blocks on the workpiece plate.

[0151] 5. Move the work-piece board after glue application to the curing position, move and place the arranged material group on the work-piece board with glue, and bond and cure the material group and the work-piece board into one body to form a material rod, preparing for the slicing process.

[0152] Preferably, after the material block is placed on the work-piece board with glue, the glue clamping fixture clamps and holds the pressure block and places it on the material block to press the material block, promoting the close contact between the material block, the work-piece board and the glue, and improving the bonding and curing effect.

[0153] Preferably, during the curing process of the material block, the curing fixture continuously clamps the material block to prevent the material block from shifting or toppling in the horizontal direction.

[0154] Preferably, the glue clamping fixture clamps the upper part of the material block, transports and places the material block on the curing position, and the glue clamping fixture maintains the clamping state; then, the curing fixture clamps the lower part of the material block. After the curing fixture clamps the material block tightly, the glue clamping fixture releases the material block. Thus, the position deviation of the material block during the transfer process can be reduced or avoided.

[0155] Preferably, when the glue clamping fixture and the curing fixture clamp multiple material blocks, they respectively use elastic clamping for the multiple material blocks; the curing fixture uses rolling clamping for the material blocks in the vertical direction.

[0156] 6. Remove the cured material rod from the curing position. Specifically, the work-piece board in the material rod is clamped by the glue clamping fixture, and the whole material rod is transferred to the work-piece board conveying line and removed from the production line through the work-piece board conveying line.

[0157] The above-described method for stick and bond of silicon blocks is particularly applicable to stick and bond of small-sized silicon blocks, and this method for stick and bond of silicon blocks can realize the equal-spacing automatic arrangement of multiple silicon blocks.

[0158] The stick and bond system and the method for stick and bond in the present utility model can fully automatically realize the parallel arrangement of small silicon blocks or other small-sized, high-hardness and brittle materials, glue application on the work-piece board, and the bonding and curing process. The component structures in the system are connected continuously, saving processing time and greatly improving the beat efficiency.

However, it should be understood that the specific description here should not be construed as a limitation on the essence and scope of the present utility model.

Among the various specific technical features described in the above specific embodiments, they can be combined in any appropriate manner without conflict.
