Description

Technical Field

[0001] The utility model relates to the field of high-hard and brittle material processing, in particular to an adhesive fixture and a stick splicing and sticking system provided with the centering platform. 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 bonded with the 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 them individually is relatively poor. To improve the slicing efficiency, it is usually necessary to perform stick splicing, that is, splicing multiple small material blocks together to form a whole stick, bonding and curing it with the workpiece plate, and then processing the spliced material stick through a slicing device.

[0004] In an automated stick splicing and sticking device, a manipulator is usually used to clamp and transport the items required during the processing. When there are many types of items, multiple manipulators with different structures need to be matched, which will occupy a large space of the device and increase the device cost.

[0005] In addition, when the manipulator needs to clamp multiple materials simultaneously, since there may be certain differences in the sizes of the multiple materials, if the clamping force of the clamping jaws is too large, some materials may be damaged, and if the clamping force is appropriately reduced, some materials may not be clamped firmly and may fall during the transfer process. Summary of the Utility Model

[0006] The purpose of the utility model is to provide an adhesive fixture and a stick splicing and sticking system, which have two types of clamping jaws, can be used to clamp a variety of different objects, and have a small fixture volume and are convenient to move. The specific technical solutions are as follows:

[0007] An adhesive fixture includes adhesive clamping jaws, and the adhesive clamping jaws include a first clamping mechanism and a second clamping mechanism. The first clamping mechanism opens or tightens along a first direction to form a first clamping space for clamping an object, and the second clamping mechanism opens or tightens along a second direction to form a second clamping space for clamping an object. The first direction and the second direction are different directions, 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.

[0008] Further, the first direction and the second direction are perpendicular to each other in the horizontal direction.

[0009] Further, the first clamping mechanism includes a first fixed clamping portion and a plurality of first elastic clamping portions. The first fixed clamping portion is disposed opposite to the plurality of first elastic clamping portions. A positioning reference surface is provided on the first fixed clamping portion, and the first elastic clamping portions are elastically clamped.

[0010] Further, the first fixed clamping portion includes a strip-shaped first cushion block. The clamping surface of the first cushion block is a plane, and the clamping surface constitutes the positioning reference surface.

[0011] Further, the first clamping mechanism includes a clamping substrate. The clamping substrate is disposed opposite to the first fixed clamping portion. The first elastic clamping portion includes a second cushion block and an elastic member. One end of the elastic member is connected to the clamping substrate, and the other end is connected to the second cushion block. The plurality of elastic members and the second cushion blocks are arranged side by side on the clamping substrate.

[0012] Further, each first elastic clamping portion includes two groups of springs. The two groups of springs are arranged vertically one above the other and are respectively connected to the upper end portion and the lower end portion of the second cushion block.

[0013] Further, the second clamping mechanism includes two fourth jaws disposed opposite to each other. The two fourth jaws can move relative to each other to achieve a clamping action, and the two fourth jaws are respectively disposed at two end positions of the first clamping mechanism.

[0014] Further, the extension length of the lower end of the fourth jaw exceeds the extension length of the lower end of the first clamping mechanism.

[0015] Further, a convex structure is further provided on the inner side surface of the lower end of the fourth jaw. The middle portion of the convex structure is concave, and both ends are convex to form a clamping card slot.

[0016] Further, it further includes an adhesive truss and an adhesive slide rail. The adhesive truss extends horizontally, the adhesive slide rail extends vertically, the adhesive jaw is slidably disposed on the adhesive slide rail, the adhesive slide rail is slidably disposed on the adhesive truss, the adhesive jaw can move vertically along the adhesive slide rail, and the adhesive slide rail can drive the adhesive jaw to move horizontally along the adhesive truss.

[0017] A stick splicing and sticking system includes a stick splicing unit, a glue applying unit, and a curing unit. The stick splicing unit includes the adhesive fixture described above. The stick splicing unit can detect the size of the material and arrange the detected materials into a material group. The glue applying unit can transport the workpiece plate for sticking the material group and automatically apply glue to the workpiece plate. The curing unit can pick up the arranged material group and the workpiece plate coated with glue, and bond and cure the material group and the workpiece plate.

[0018] The adhesive fixture and the stick splicing and sticking system of the present utility model have the following advantages:

[0019] 1. The two types of jaws are combined, enabling the adhesive fixture to pick up more than two different objects. Since the two types of jaws share a clamping space, the volume and occupied space of the adhesive fixture are significantly reduced, making it more convenient to move in the rod splicing and gluing system.

[0020] 2. By adopting the cooperation of a fixed clamping part and an elastic clamping part, it is ensured that when picking up multiple material blocks simultaneously, the clamping position can be accurately located, and the dimensional deviation between the material blocks can be accommodated, providing pressing force compensation to ensure the stability of clamping without damaging the material blocks.

[0068] For a better understanding of the purpose, structure and function of the present utility model, the adhesive fixture structure and the stick - splicing system of the present utility model will be described in detail below with reference to the accompanying drawings.

[0069] As Figure 1 and Figure 2 shown, the stick - splicing system in the present utility model is used for automatically arranging, gluing and curing silicon blocks with small volume and thin thickness, so as to automatically integrate multiple small silicon blocks into a larger and integral silicon block rod, preparing for the subsequent slicing process.

[0070] Such silicon blocks with small volume and thin thickness can be cut and processed from the edge scraps generated during the process of slicing silicon rods, or can be cut and processed from the head and tail scraps generated during the process of truncating silicon rods. Since the corner scraps such as edge scraps and head - tail scraps usually have small volume and irregular shapes, 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 system of the present utility model to form a large and long silicon block rod, and then automatically sliced by an automatic slicing device. Of course, similar small silicon blocks generated by other means can also be spliced and integrated through the stick - splicing system of the present utility model, not limited to the small silicon blocks processed from edge scraps and head - tail scraps. In addition to silicon rods, other high - hardness and brittle materials, such as sapphire, ceramics, etc., can also be spliced and integrated by using the stick - splicing system of the present utility model.

[0071] Specifically, as Figure 1 and Figure 2 shown, the stick - splicing system includes a stick - splicing unit 1, a glue - applying unit 2 and a curing unit 3 which are arranged in cooperation. Among them, the stick - splicing unit 1 is used to detect whether the size of the silicon block 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 - splicing 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.

[0072] Preferably, the above-mentioned stick splicing and stick gluing system is used to automatically arrange multiple small silicon blocks at equal intervals. For the spliced ​​silicon block rods, since gaps will be formed between two adjacent silicon blocks, the cutting wire mesh used for slicing needs to be specially configured during the slicing process so that the cutting position of the cutting wire mesh can be adapted to the multiple gaps on the silicon block rods. The automatic arrangement of equal intervals can make it easier to configure the silicon block rods with suitable cutting wire meshes, especially when batch slicing is performed, the cutting wire mesh does not need to be repeatedly readjusted, which helps to further improve production efficiency and ensure slicing quality.

[0073] Further, if Figure 3 and Figure 4 As shown, the rod assembly unit 1 includes a material distribution mechanism, a centering platform and a rod arrangement assembly, wherein the material distribution mechanism is used to load silicon blocks, and automatically complete the detection of the thickness of the silicon blocks during the loading process, and the silicon blocks that meet the thickness standards 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 arrangement assembly at the same time; the rod arrangement assembly picks up multiple silicon blocks on the centering platform at the same time, and adjusts the placement position of the silicon blocks for the second time, reduces the spacing between the multiple silicon blocks, and then places the multiple silicon blocks with adjusted spacing on the rod assembly platform. When the rod arrangement assembly adjusts the next group of silicon blocks, the next group of silicon blocks is sequentially placed on the front side or the rear side of the previous group of silicon blocks, so that the front and rear groups of silicon blocks are placed continuously. The material distribution mechanism, the centering platform and the rod arrangement assembly can arrange multiple small silicon blocks into a row of silicon blocks with a length sufficient to be spliced ​​into a whole rod by repeating the above operations.

[0074] Further, if Figures 4 to 7 As 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.

[0075] Further, the blanking fixture 11 includes a blanking truss 111, a blanking slide rail 112, and a blanking jaw 113. The blanking truss 111 extends horizontally, the blanking slide rail 112 extends vertically, the blanking jaw 113 is slidably arranged on the blanking slide rail 112, and the blanking slide rail 112 is slidably arranged on the blanking truss 111. The blanking jaw 113 can move up and down vertically along the blanking slide rail 112, and the blanking slide rail 112 can drive the blanking jaw 113 to move horizontally along the blanking truss 111. The blanking truss 111 is located above the feeding conveyor line 13 and the NG conveyor line 14, so as to facilitate the blanking jaw 113 to pick up the silicon blocks on the feeding conveyor line 13 and transfer the silicon blocks to the NG conveyor line 14 or to the centering platform of the rod assembling unit 1.

[0076] Further, as Figures 8 to 11 shown, the blanking jaw 113 includes a jaw body 114, a rotating assembly 115, and a chuck assembly 116. The chuck assembly 116 is connected to the jaw body 114 through the rotating assembly 115. The chuck assembly 116 can clamp an object, and the rotating assembly 115 can make the chuck assembly 116 rotate, thereby changing the placement direction of the object clamped on the chuck assembly 116. The jaw body 114 is slidably connected to the blanking slide rail 112 and can drive the jaw body 114 and the object clamped on the jaw body 114 to slide up and down along the blanking slide rail 112. Specifically, the chuck assembly 116 includes a first base 117. A centering cylinder is arranged on the first base 117, and a first chuck is arranged at each end of the centering cylinder. The centering cylinder can drive the two first chucks to approach or separate from each other to clamp objects such as silicon blocks. The rotating assembly 115 includes a rotating shaft. The rotating shaft is connected to the jaw body 114 through a bushing. The first base 117 of the chuck assembly 116 is fixedly connected to the rotating shaft. A driving mechanism, such as a motor, is also arranged on the jaw body 114. The driving mechanism is connected to the rotating shaft through a belt. The driving mechanism can drive the rotating shaft to rotate through the belt, thereby making the first base 117 and the first chucks on the first base 117 rotate and changing the placement position of the object clamped on the first chucks. Preferably, the chuck assembly 116 is provided with Figure 8 the first clamping position shown in Figure 9 and the second clamping position shown in

[0077] The reason why the chuck assembly 116 in the above blanking jaw 113 is set to be rotatable is that the rod assembling unit 1 and the rod assembling and sticking system in this solution are especially suitable for small silicon blocks processed from corner materials such as side skins and head and tail materials, such as Figure 46As shown, such silicon blocks are usually thin and long. Therefore, during the loading process, it is more stable to transport them in the flat position shown in Figure 12 . However, when splicing the rods, in order to meet the requirements of slicing processing, the silicon blocks need to be vertically arranged along the long side as shown in Figure 47 and then spliced. In this solution, the silicon blocks are placed flat on the loading conveyor line 13 for transportation and thickness detection. As shown in Figure 8 , the material separating gripper 113 grabs the flat silicon block. If the thickness of the silicon block does not meet the preset error range, the material separating gripper 113 directly moves to the NG conveyor line 14 and drops the silicon block. If the thickness of the silicon block meets the preset error range, as shown in Figure 9 , the rotating component 115 in the material separating gripper 113 drives the chuck component 116 to rotate 90 degrees, changing the silicon block from the flat 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.

[0078] Furthermore, as shown in Figures 12 to 17 , the detection component 12 is arranged close to the loading conveyor line 13, including a first detection piece 121 and a second detection piece 122. The first detection piece 121 is located above the loading conveyor line 13, and the second detection piece 122 is located below the loading 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 loading 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 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 them can be measured. When the silicon block is placed on the loading 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 loading 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 loading 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 as H = h - h1 - h2. The first detection piece 121 and the second detection piece 122 are preferably laser sensors.

[0079] Specifically, as shown in Figure 12 and Figure 15As shown in the figure, the loading conveyor line 13 includes a loading table 131. Two groups of conveyor belts arranged side by side and moving synchronously are provided on the loading table 131. A detection gap 123 is formed between the two groups of conveyor belts. Two groups of loading rollers 132 are also provided on the loading table 131. The two groups of loading rollers 132 are respectively arranged on both sides of the loading table 131, at the outer edges of the two groups of conveyor belts. The distance between the two groups of loading rollers 132 is roughly matched with the width of the silicon block. The two groups of rollers extend outward toward the outside of the conveyor belts at the loading end of the conveyor belts, forming a flared structure. When the silicon block starts to be transported from the loading end of the conveyor belt, the two sides of the silicon block can be in sliding contact with the loading 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, making the silicon block located in the middle position between the two groups of conveyor belts, avoiding the silicon block being placed obliquely or the position shifting. The flared structure at the ends of the two groups of rollers is more convenient for the silicon block to enter the loading conveyor line 13.

[0080] During the transportation of the silicon block on the loading conveyor line 13, the thickness is detected by the detection component 12, and then it continues to move to the material separation fixture 11 for material separation and clamping. In order to prevent the silicon block from continuously moving out of the clamping position on the loading conveyor line 13, as Figure 15 shown, a limit stop block 133 is also provided at the end of the conveyor belt. The limit stop block 133 is erected above the two groups of conveyor belts and can block the silicon block on the conveyor belt from continuing to move.

[0081] 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 block, 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, so as to facilitate the adjustment of the relative positions between the first detection piece 121 and the second detection piece 122.

[0082] 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 toward 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 toward 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.

[0083] Preferably, the second support 124 is fixedly arranged on the loading table 131, and the second detection piece 122 is fixedly arranged on the second support 124 so that the second detection piece 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 detection piece 121. The first detection piece 121 is movably arranged on the second connecting rod and can move along the second connecting rod to adjust the position. The first detection piece 121 can freely adjust its position through the first connecting rod and the second connecting rod so that the first detection piece 121 and the second detection piece 122 have a suitable relative position for detection, realizing precise control of position and accuracy and accurately detecting whether the thickness of the silicon block is qualified. Setting the first detection piece 121 located above in a form that can be movably adjusted is more convenient for the operation of position adjustment. Of course, the second detection piece 122 can also be set in a form that can be movably adjusted, and the first detection piece 121 can be set as a positioning reference position.

[0084] The detection component 12 arranged on the loading conveyor line 13 will automatically detect the thickness of the silicon blocks moving on the loading conveyor line 13 to check whether the thickness of the silicon blocks is within the error range. When the silicon block reaches the detection position of the detection component 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 blocks that meet the requirements will be clamped by the sorting fixture 11 and transported to the centering platform, while the silicon blocks that do not meet the requirements will be clamped by the sorting fixture 11 and transported to the NG conveyor line 14.

[0085] In the above-mentioned sorting mechanism of the rod splicing and sticking system, by reasonably setting the structure and cooperation mode of the sorting fixture, the detection component and the loading conveyor line, the sorting mechanism can automatically complete the feeding, detection and classification and transfer of materials, with a high degree of automation, improving the working efficiency of the equipment and reducing labor costs. By setting the detection component in a form with adjustable position, it is convenient to calibrate and debug the detection component, improving the accuracy of material detection. The sorting fixture is arranged in a rotatable manner, improving the flexibility of the sorting mechanism, being able to automatically adjust the position of the material, and facilitating subsequent operations such as discharging and splicing and sticking of the material.

[0086] Further, as Figure 18 and Figure 19 shown, one end of the centering platform is arranged close to the sorting mechanism, and the other end is arranged close to the rod arranging component. The centering platform can receive the silicon blocks that pass the detection transmitted by the sorting mechanism, adjust the positions of the silicon blocks, and transfer the silicon blocks with adjusted positions to the rod arranging component, preparing for the subsequent rod splicing and sticking process.

[0087] Specifically, the centering platform includes a platform bracket 15, on which two sets 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 sets of centering jaws 162 are arranged side by side. The spacing between adjacent two sets of centering jaws 162 is equal. One detection device 163 is arranged on each set of centering jaws 162, and the detection device 163 is preferably a sensor. The blanking fixture 11 in the blanking mechanism places the qualified silicon blocks in a vertical direction 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 push and squeeze the silicon block from both sides of the silicon block respectively to realize the centering operation of the silicon block position; the blanking fixture 11 starts to place the silicon blocks at the first set of centering jaws 162 and ends until silicon blocks are placed on all three sets of centering jaws 162. As Figure 18 and Figure 19 shown, the two sets of moving sliders 16 on the platform bracket 15 are transported in parallel. After the positions of the silicon blocks on the three sets 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 sets of moving sliders 16 can move independently of each other without interference. The setting method of alternately transporting the two sets of moving sliders 16 and multi-station centering adjustment of the positions of the three sets of centering jaws 162 greatly improves the working efficiency of the centering platform.

[0088] During the process of transferring the silicon rod from the blanking mechanism to the centering platform, the blanking 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 blanking 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.

[0089] 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 slide base 161. By adjusting the installation angle of the adjustment plate 164 on the slide base 161, the clamping position of the centering jaw 162 can be made to tend to be parallel to the delivery position where the silicon block is delivered by the splicing bar fixture, thereby avoiding dislocation of the silicon block during centering adjustment. Specifically, an arc-shaped connection hole 165 is provided on the adjustment plate 164. A pin is arranged in the connection hole 165. The adjustment plate 164 is connected to the slide base 161 through the cooperation of the pin and the connection hole 165, and the fixed connection position of 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.

[0090] Specifically, as Figure 19 shown in the figure, two sets of linear guides are arranged side by side on the platform bracket 15. Sliders are arranged below the slide base 161 of the moving slide 16, and the sliders are slidably connected to the linear guides so that the slide base 161 is slidably arranged on the platform bracket 15. A conveyor belt is also arranged on the linear guide. As Figure 20 shown in the figure, conveyor belt clamping members 166 are correspondingly arranged on the slide base 161. There are two sets of clamping members 166, respectively located at both ends of the slide base 161. The clamping members 166 can clamp the conveyor belt on the linear guide. The conveyor belt can move along the extension direction of the linear guide under the drive of the drive assembly, thereby driving the moving slide 16 to reciprocate along the linear guide. The clamping member 166 includes a fixing plate fixedly connected to the slide 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.

[0091] Preferably, each set of linear guides includes two parallel tracks. Two sets of sliders are correspondingly arranged on the slide base 161. The conveyor belt on the linear guide 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 slide base 161. Adopting this setting method is beneficial to improving the stability of the moving slide 16 during the sliding process.

[0092] Preferably, the widths of the adjusting plate and the fixing plate are greater than the width of the conveyor belt on the linear guide. 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.

[0093] Preferably, the centering jaws 162 on the two sets of moving sliders 16 are arranged opposite to each other. That is, the centering jaws 162 on the first moving slider 16 are arranged towards the direction where the second moving slider 16 is located, and the centering jaws 162 on the second moving slider 16 are arranged towards the direction where the first moving slider 16 is located. By adopting this setting method, the centering stations on the two sets of moving sliders 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 working efficiency.

[0094] In the specific implementation manner of the above-mentioned centering platform, setting the centering platform as two sets of moving sliders 16, with each set of moving sliders 16 configured with three sets 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 working 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 sliders 16 can also be arranged on the platform bracket 15, and two or more than three sets of centering jaws 162 can also be arranged on each moving slider 16 to improve production efficiency.

[0095] The centering platform in the above-mentioned rod splicing and sticking system improves the transfer efficiency by alternately reciprocating sliding of the double moving sliders, better quickly connecting the upstream and downstream processes. The setting of multiple centering stations can also adjust the positions of multiple clamped objects at the same time, further improving the working 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 slider base on the platform bracket can make the operation of the moving slider more stable and smooth on the basis of ensuring the working efficiency.

[0096] 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 set of silicon blocks with their positions preliminarily adjusted on the centering platform, further reduce the spacing between adjacent silicon blocks, and then arrange this set 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).

[0097] 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 vertically 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 placement action until a complete stick is formed.

[0098] 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.

[0099] 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.

[0100] 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 center positions of the silicon blocks on the second chuck 175 and the two silicon blocks on the third chucks 176.

[0101] Preferably, as Figure 23 and Figure 24As shown, the second chuck 175 includes a first driving part and two first clamping parts 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 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. Adopting the above setting method is beneficial to adjusting the tiny distance between adjacent silicon blocks on the rod-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.

[0102] The rod-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 centeringly on both sides, which can clamp three silicon blocks on the centering platform at the same time. This setting method can not only improve the working efficiency of rod arranging of the silicon blocks, but also be beneficial to accurately controlling the distance between adjacent silicon blocks, and is more convenient for adjusting the distance between adjacent silicon blocks. Of course, in addition to the above preferred setting method, the second jaws and third jaws on the rod-assembling jaw 173 can also be both set in a movable form, and the number of jaws for clamping the silicon blocks can also be set to two or more than three.

[0103] Furthermore, detection devices are arranged on both the second chuck 175 and the third chuck 176. The detection devices are preferably sensors. When the rod-assembling jaw 173 in the rod-assembling fixture 17 moves to the centering platform, the detection devices on the second chuck 175 and the third chuck 176 detect the silicon block, then 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 to realize the clamping operation of the silicon block.

[0104] Specifically, 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 arranged on the support frame 181. A buffer pad 183 is arranged 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 arranged 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 blocks fixed, and prevent the silicon blocks from shaking or tilting and collapsing.

[0105] 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.

[0106] 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 cups is roughly flush with the upper surface of the buffer pad 183. When the silicon blocks are moved to the stick-assembling table 18, the two ends of the lower surface of the silicon blocks can abut against the buffer pad 183 to ensure the stable placement of the silicon blocks. The middle part of the lower surface of the silicon blocks can be adsorbed and fixed by the vacuum suction cups to prevent the silicon blocks from shifting or toppling.

[0107] 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.

[0108] Furthermore, a quantity detection device 185 is also arranged 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.

[0109] In the stick arrangement assembly of the stick splicing and stick gluing system, two groups of movable chucks are based on the fixed chuck in the middle, and the positions are adjusted in a centered manner, which is conducive to improving the adjustment accuracy of the spacing between the clamped objects and enabling the relative positions of the clamped objects to be accurately controlled. The specific structural design of the chuck is conducive to the adjustment of the small spacing between adjacent clamped objects. At the same time, adjacent chucks will not interfere with each other during the movement, which is more conducive to the position arrangement of the clamped objects. The fixing device on the stick splicing table can position and fix the material blocks placed on the stick splicing base plate, so that the positions of the material blocks are fixed and unchanged, and at the same time prevent the material blocks from shaking or tilting and collapsing. A spacing space is formed between the quantity detection device on the stick splicing table and the stick splicing table, which can avoid position interference between the detection device and the material block clamp when placing or clamping the material block.

[0110] Further, if Figure 1 and Figure 2 As shown, the gluing unit 2 includes a workpiece plate conveying line and a gluing device. The workpiece plate conveying line is used to transport the workpiece plates. The gluing device can automatically perform gluing operations on the workpiece plates placed on the workpiece plate conveying line. The gluing fixture in the curing unit 3 can clamp the workpiece plate coated with glue onto the curing table in the curing unit 3, and then clamp the arranged silicon block group and place it on the workpiece plate, thereby bonding and curing the workpiece plate and the silicon block group to form a silicon block rod that is convenient for subsequent slicing processing.

[0111] Further, if Figure 29 and Figure 30 As shown, the curing unit 3 is arranged on one side of the glue coating unit 2, including a curing table 31, a glue clamp 32 and a curing clamp 33. The glue clamp 32 can be moved to the glue coating unit 2 to clamp the workpiece plate after glue coating, and the workpiece plate is placed on the curing table 31, and then moved to the stick assembly table 18 in the stick assembly unit 1 to grab a group of arranged silicon blocks, and the silicon block group is placed on the workpiece plate after glue coating on the curing table 31, so as to bond the silicon block group to the workpiece plate. The adhesive clamp 32 clamps the upper part of the silicon block group. When the adhesive clamp 32 places the silicon block group, the curing clamp 33 arranged on the curing table 31 first clamps the lower side of the silicon block group. After the curing clamp 33 clamps the silicon block group, the adhesive clamp 32 releases the silicon block group. This operation is to avoid the problem of position displacement or tipping of each silicon block on the workpiece plate when the adhesive rod clamp releases the silicon block group. The curing clamp 33 can continuously clamp the silicon block during the process of bonding and curing the silicon block group and the workpiece plate, ensuring that each silicon block is combined with the workpiece plate at a preset position, and finally obtaining a silicon block rod that meets the requirements.

[0112] Specifically, Figure 33As shown, 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 blocks, 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 blocks, and with the cooperation of the gravity of the pressure-holding block 312, enables the silicon blocks to be in full contact with the glue on the workpiece plate, completing the bonding and curing operation. Positioning pins matching the workpiece plate are also provided on the curing table 31 for positioning the workpiece plate when placing it. 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.

[0113] As Figure 29 and Figure 30 shown, 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 along the glue-bonding slide rail 322 in the vertical direction, 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 rods that have completed bonding and curing on the curing table 31.

[0114] Specifically, as Figure 31 , Figures 34 to 40 shown, 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.

[0115] 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, and on the basis of increasing the grasping function of the glue clamping jaw 323, the volume and occupied space of the glue clamping jaw 323 are reduced.

[0116] 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 part, the first fixed clamping part 324 and the first elastic clamping part 325 can move relatively. 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 the corresponding silicon block to ensure that the plurality of silicon blocks are stably clamped simultaneously without being damaged.

[0117] 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 constitute the 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 a silicon block group, the spring in the first elastic clamping part 325 can provide elastic buffering when the second cushion block 327 squeezes the side wall of the silicon block, and provide corresponding pressing force compensation for different size situations of different silicon blocks.

[0118] 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 beneficial to improving the pressing force compensation effect and has better clamping stability.

[0119] Preferably, the first cushion block and the second cushion block 327 are nylon cushion blocks.

[0120] 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 silicone cushion blocks that can provide elastic clamping, etc.

[0121] 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 various objects such as a workpiece plate and a pressure-holding block 312, and avoid movement interference with the first clamping mechanism.

[0122] 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 both ends are convex to form a clamping groove. When the fourth jaw 328 clamps a workpiece plate and a pressure-holding plate, the object to be clamped can be clamped in the clamping groove, thereby improving the clamping stability and avoiding loosening of the object to be clamped and causing processing accidents.

[0123] 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.

[0124] The glue fixture 32 in the above-mentioned stick-splicing 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 rod after bonding and curing is achieved. The two types of jaws are combined, enabling the glue fixture to pick 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 fixture and making it more convenient to move in the stick-splicing 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 dimensional deviation between the material blocks can be adapted, providing a pressing force compensation to ensure the stability of clamping without damaging the material blocks.

[0125] 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-splicing fixture, pick up multiple silicon blocks to be spliced and bonded from the glue 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.

[0126] Similar to the glue 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 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 relative to each other 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 realize 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 its corresponding silicon block to ensure that the multiple silicon blocks are stably clamped simultaneously without being damaged.

[0127] 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 be in full and close contact with the workpiece plate and the adhesive and bond, 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 downward slightly 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.

[0128] 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.

[0129] Preferably, as Figure 43 shown, each second elastic clamping portion 332 includes two groups of springs, and the two groups 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.

[0130] 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 replaced as a whole with a silicone roller 336 that can provide elastic clamping, etc.

[0131] 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 part 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 thus 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.

[0132] 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 distance between rollers on different second elastic clamping portions 332 are different to match silicon blocks of different specifications.

[0133] The curing fixture in the above-mentioned stick splicing and sticking system adopts a setting method in which the fixed clamping portion and the elastic clamping portion are combined. 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 blocks move slightly downward in the vertical direction while remaining relatively stationary in the horizontal direction, so as to enhance the close contact between the material blocks, the workpiece plate and the adhesive.

[0134] Furthermore, as Figure 1 and Figure 2As shown in the figure, the stick assembling and gluing system further includes a truss assembly 5, which is erected above the stick assembling unit 1, the glue coating unit 2 and the curing unit 3. The truss assembly 5 extends in the extending direction of the X-axis in the horizontal direction. The stick assembling truss 171 in the stick assembling jig 17 and the gluing 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 gluing truss 321 extend in the extending 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 gluing truss 321 and can reciprocate along the gluing truss 321 in the Y-axis direction. The stick assembling slide rail 172 and the glue applying slide rail 322 extend in the extending 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 the three-dimensional space to flexibly clamp objects.

[0135] In the stick assembling and gluing system of this solution, by reasonably configuring the material distribution mechanism, the centering platform, the stick arranging component, the curing table, the glue applying jig and the curing jig, the positioning and arranging of the silicon blocks can be realized automatically, quickly and efficiently, avoiding the position deviation or dumping 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 readjusted repeatedly, which helps to further improve the production efficiency and ensure the slicing quality.

[0136] This solution also discloses a stick assembling and gluing method, as Figure 45 shown, which specifically includes:

[0137] 1. Feed the material blocks, detect whether the material blocks are qualified, and distribute the material blocks according to the detection results.

[0138] The material blocks are fed through the feeding conveyor line. The thickness of the material blocks is detected during the feeding 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.

[0139] 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.

[0140] The material blocks with qualified thickness are adjusted in position. The material blocks are picked up by the material separating fixture and rotated 90 degrees along the length direction, from the horizontal placement position to the vertical placement position.

[0141] The material blocks adjusted to the vertical placement position are transferred by the material separating fixture to the centering platform for centering adjustment. The centering platform includes multiple centering stations, and multiple material blocks are centered and adjusted simultaneously.

[0142] The assembling rod fixture picks up multiple material blocks that have been adjusted in centering, and adjusts the spacing between the material blocks to reduce the spacing between adjacent material blocks.

[0143] Preferably, there are at least two groups of moving sliding tables on the centering platform, preferably two groups. The two groups of moving sliding tables reciprocate alternately between the loading end where the material separating fixture is located and the rod arranging end where the assembling rod fixture is located. When the position adjustment of the material blocks on any one group of moving sliding tables is completed, they move from the loading end to the rod arranging end and wait to be picked up. After the material blocks are picked up, the moving sliding table returns to the loading end to repeat the centering adjustment operation. The two groups of moving sliding tables operate independently of each other and do not interfere with each other.

[0144] Preferably, each group of moving sliding tables includes three centering stations, and the spacing between the stations is equal; the material separating fixture places the material blocks on any one of the centering stations, and the centering station centers and clamps the material blocks. The material separating fixture releases the material blocks and repeats the next loading, material separating, and placing operations. The material separating fixture places materials on the three centering stations in sequence until materials are placed on all three centering stations and then it ends.

[0145] Preferably, the assembling rod fixture simultaneously picks up three material blocks on the moving sliding table, and makes the material blocks on both sides move synchronously towards the material block in the middle to reduce the spacing between the three material blocks.

[0146] 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 picked up for bonding and curing.

[0147] Preferably, the assembling rod fixture transports the material blocks from the moving sliding table to the rod assembling table for discharging materials. The adsorption device on the rod assembling table can adsorb the material blocks to prevent the material blocks from slightly shaking or tilting and collapsing.

[0148] 4. Load the workpiece plate and apply glue on the workpiece plate.

[0149] The workpiece plate is loaded through the workpiece plate conveying line, and the automatic glue applying device on one side of the workpiece plate conveying line applies glue on the material block bonding surface of the workpiece plate.

[0150] 5. Move the workpiece plate after gluing to the curing position, move and place the arranged material group on the glued workpiece plate, and bond and cure the material group and the workpiece plate into one body to form a material rod, preparing for the slicing process.

[0151] Preferably, after the material block is placed on the glued workpiece plate, the adhesive fixture then 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 workpiece plate and the adhesive, and improving the bonding and curing effect.

[0152] Preferably, during the curing process of the material block, the material block is continuously clamped by the curing fixture to prevent the material block from shifting or tipping in the horizontal direction.

[0153] Preferably, the adhesive fixture clamps the upper part of the material block, transports and places the material block on the curing position, and the adhesive fixture remains in the clamping state; then, the curing fixture clamps the lower part of the material block. After the curing fixture clamps the material block, the adhesive fixture releases the material block. Thus, the position offset of the material block during the transfer process can be reduced or avoided.

[0154] Preferably, when the adhesive fixture and the curing fixture clamp multiple material blocks, elastic clamping is respectively adopted for the multiple material blocks; the curing fixture adopts rolling clamping for the material blocks in the vertical direction.

[0155] 6. Remove the cured material rod from the curing position. Specifically, the workpiece plate in the material rod is clamped by the adhesive fixture, and the whole material rod is transferred to the workpiece plate conveyor line and removed from the production line through the workpiece plate conveyor line.

[0156] The above-described method for splicing and bonding rods is particularly suitable for splicing and bonding rods of small-sized silicon blocks, and this method for splicing and bonding rods can realize the equal-spacing automatic arrangement of multiple silicon blocks.

[0157] The splicing and bonding rod system and the splicing and bonding rod method in the present invention can fully automatically realize the parallel arrangement, workpiece plate gluing, and bonding and curing processes of small silicon blocks or other small-sized, high-hardness and brittle materials. The component structures in the system are connected continuously, saving processing time and greatly improving the beat efficiency.
