[0026] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 3 The bonding tool 100 for silicon rods according to the embodiment of the present utility model is described, comprising: a mounting bracket 10 and a clamping assembly 20.

[0027] Specifically, if Figure 1-Figure 3 As shown, the mounting bracket 10 includes a partition plate 11 , and the clamping assembly 20 is suitable for stopping the silicon rod 30 against the partition plate 11 .

[0028] Combination Figure 1-Figure 3 , multiple silicon rods 30 are placed in the mounting bracket 10, and the partition 11 can divide the mounting bracket 10 into multiple areas for accommodating the silicon rods 30. One side surface of the silicon rod 30 along the first direction A or the second direction B of the mounting bracket 10 abuts against one side surface of the partition 11 along the thickness direction, and the other side surface of the silicon rod 30 along the first direction A or the second direction B of the mounting bracket 10 abuts against the clamping assembly 20, and the clamping assembly 20 applies pressure to the silicon rod 30 to press the silicon rod 30 against the partition 11, so that the clamping assembly 20 can complete the integrated clamping of the silicon rod 30 and the mounting bracket 10.

[0029] According to the bonding tool 100 for silicon rods in the embodiment of the utility model, the mounting bracket 10 is used to accommodate the silicon rod 30, and the setting of the partition 11 is convenient for limiting the silicon rod 30 in the first direction A and the second direction B. The clamping assembly 20 applies pressure to the silicon rod 30 so that the silicon rod 30 is in close contact with the partition 11 to complete the positioning of the silicon rod 30 in the mounting bracket 10. At the same time, the clamping assembly 20 further applies pressure to the silicon rod 30 to complete the integrated clamping of the silicon rod 30 and the mounting bracket 10, so as to move the silicon rod 30 and the mounting bracket 10 to the glue layer at the same time, so as to facilitate the positioning of the silicon rod 30 during the bonding process, avoid the bonding and slicing abnormalities caused by inaccurate positioning during the bonding process of the silicon rod 30, and improve the finished product yield of the silicon rod 30 slices.

[0030] According to some embodiments of the present invention, Figure 2 As shown, the partition 11 includes: a first partition 12 and a second partition 13, the first partition 12 intersects with the second partition 13, the first partition 12 and the second partition 13 define at least one receiving groove 14, the silicon rod 30 is located in the receiving groove 14, and the silicon rod 30 abuts against the first partition 12 and the second partition 13 respectively. One side surface of each silicon rod 30 along the first direction A of the mounting bracket 10 abuts against one side surface of the second partition 13 along the thickness direction, and one side surface of each silicon rod 30 along the second direction B of the mounting bracket 10 abuts against one side surface of the first partition 12 along the thickness direction, that is, each silicon rod 30 has at least two side surfaces abutting against the partition 11. Therefore, the first partition 12 and the second partition 13 define a plurality of receiving grooves 14 to facilitate accommodating a plurality of silicon rods 30, and can simultaneously complete the positioning of a plurality of silicon rods 30, thereby improving the working efficiency of the sticking process. The setting of the first partition 12 and the second partition 13 can limit the silicon rod 30 and realize the positioning of the silicon rod 30.

[0031] According to some embodiments of the present invention, Figure 2 As shown, the first partition 12 extends along the first direction A, and the second partition 13 extends along the second direction B, and the first direction A is perpendicular to the second direction B. The first partition 12 and the second partition 13 are in a cross-shaped structure, and the first partition 12 and the second partition 13 divide the mounting bracket 10 into four receiving grooves 14, and each receiving groove 14 is provided with a silicon rod 30. Therefore, the first partition 12 can limit the silicon rod 30 in the second direction B, and the second partition 13 can limit the silicon rod 30 in the first direction A. The first partition 12 and the second partition 13 jointly complete the positioning of the silicon rod 30 in the first direction A and the second direction B.

[0032] According to some embodiments of the present invention, Figure 2As shown, there are multiple accommodating grooves 14, and the multiple accommodating grooves 14 are arranged at intervals along the circumference of the mounting bracket 10; the clamping assembly 20 includes: at least one first clamping member 21 and at least one second clamping member 22, the first clamping member 21 is located on one side of the first direction A of the mounting bracket 10, and the second clamping member 22 is located on one side of the second direction B of the mounting bracket 10, and the first clamping member 21 and the second clamping member 22 are respectively abutted against the two sides of the same silicon rod 30 away from the partition 11.

[0033] The first partition 12 and the second partition 13 define four accommodating grooves 14, and the four accommodating grooves 14 are arranged at intervals along the first direction A and the second direction B. The four silicon rods 30 are respectively arranged in the four accommodating grooves 14. The first clamping member 21 is suitable for abutting against the other side surface of the silicon rod 30 along the first direction A, and the second clamping member 22 is suitable for abutting against the other side surface of the silicon rod 30 along the second direction B. That is, one side surface of each silicon rod 30 along the first direction A abuts against one side surface of the second partition 13 along the thickness direction, and the other side surface of the silicon rod 30 along the first direction A abuts against the first clamping member 21. One side surface of each silicon rod 30 along the second direction B abuts against one side surface of the first partition 12 along the thickness direction, and the other side surface of the silicon rod 30 along the second direction B abuts against the second clamping member 22. The first clamping member 21 and the second clamping member 22 apply pressure to the silicon rod 30 so that the silicon rod 30 is close to the partition 11.

[0034] Thus, the first clamping member 21 cooperates with the second partition 13 to limit the silicon rod 30 in the first direction A, and the second clamping member 22 cooperates with the first partition 12 to limit the silicon rod 30 in the second direction B. The first clamping member 21 and the second clamping member 22 apply pressure to the silicon rod 30 to fix the silicon rod 30 on the mounting bracket 10, so as to complete the integrated clamping of the silicon rod 30 and the mounting bracket 10, and facilitate the clamping assembly 20 to move the silicon rod 30 and the mounting bracket 10 at the same time.

[0035] According to some embodiments of the present invention, Figure 3 As shown, the mounting bracket 10 includes: a bracket body 15 and a plurality of support members 16, the partition 11 is arranged in the bracket body 15, the plurality of support members 16 are arranged at the bottom of the bracket body 15, one end of the plurality of support members 16 is connected to the bracket body 15, and the plurality of support members 16 are arranged at intervals along the circumference of the mounting bracket 10.

[0036] The bracket body 15 is a frame structure, and the bracket body 15 includes a first frame 151, a second frame 152 and four connecting rods 153. The first frame 151 and the second frame 152 are both rectangular frame structures, and the first frame 151 and the second frame 152 are arranged at intervals along the third direction C of the mounting bracket 10, and the first frame 151 and the second frame 152 are opposite to each other along the third direction C of the mounting bracket 10. The connecting rod 153 is used to connect the first frame 151 and the second frame 152, and the connecting rod 153 extends along the third direction C of the mounting bracket 10, one end of the connecting rod 153 along the third direction C is connected to the top corner of the first frame 151, and the other end of the connecting rod 153 along the third direction C is connected to the top corner of the second frame 152, and the four connecting rods 153 are arranged in parallel and at intervals, and one end of the four connecting rods 153 along the third direction C is respectively connected to the four top corners of the first frame 151, and the other end of the four connecting rods 153 along the third direction C is respectively connected to the four top corners of the second frame 152.

[0037] The partition 11 is arranged in the bracket body 15 and connected to the first frame 151 and the second frame 152. The support member 16 extends along the third direction C of the mounting bracket 10. There are four support members 16, and the four support members 16 are respectively connected to the four top corners of the second frame 152. One end of the support member 16 along the third direction C is connected to the top corner of the second frame 152, and the other end of the support member 16 along the third direction C extends in a direction away from the second frame 152.

[0038] Thus, the support body 15 is connected with the partition 11 to define four receiving grooves 14, and the frame structure of the support body 15 facilitates the first clamping member 21 and the second clamping member 22 to pass through the mounting bracket 10 and directly stop against the silicon block. A plurality of support members 16 are arranged at the bottom of the support body 15 along the third direction C. The arrangement of the support members 16 facilitates the support of the mounting bracket 10, so that when the clamping assembly 20 moves the silicon rod 30 and the mounting bracket 10 onto the glue layer, the arrangement of the support members 16 can prevent the mounting bracket 10 from contacting the glue layer, thereby facilitating the bonding of the glue rod.

[0039] According to some embodiments of the present invention, Figure 3 As shown, the distance between the bottom surface of the partition 11 and the end surface of the other end of the support member 16 is greater than or equal to the distance between the bottom surface of the silicon rod 30 and the end surface of the other end of the support member 16 .

[0040] The distance between the bottom surface of the partition 11 and the end surface of the other end of the support member 16 is the length of the support member 16 along the third direction C. Along the third direction C of the mounting bracket 10, the length of the support member 16 is greater than or equal to the distance between the bottom surface of the silicon rod 30 and the end surface of the other end of the support member 16.

[0041] Thus, when the clamping assembly 20 moves the silicon rod 30 and the mounting bracket 10 onto the adhesive layer to complete the bonding of the rod, the distance between the silicon rod 30 and the adhesive layer is closer than the distance between the partition 11 and the second frame 152 and the adhesive layer, which facilitates the silicon rod 30 to contact the adhesive layer before the mounting bracket 10, so as to smoothly complete the bonding of the adhesive rod.

[0042] According to some embodiments of the utility model, it also includes: a connecting plate, the connecting plate is suitable for placing the silicon rod 30, and the projection of the silicon rod 30 on the mounting bracket 10 is located within the projection of the connecting plate on the mounting bracket 10. The connecting plate is placed on the workbench, the clamping assembly 20 clamps the silicon rod 30 and the mounting bracket 10 on the workbench as a whole and places the mounting bracket 10 and the silicon rod 30 above the connecting plate, and the other end of the support member 16 of the mounting bracket 10 is in contact with the workbench surface, and the plurality of support members 16 are located on the outer peripheral side of the connecting plate and do not contact the connecting plate. Along the third direction C of the mounting bracket 10, the projection of the connecting plate is located within the projection of the mounting bracket 10. Thus, when the silicon rod 30 is prevented from being placed on the connecting plate, the mounting bracket 10 does not contact the connecting plate, and the projection of the silicon rod 30 on the mounting bracket 10 is located within the projection of the connecting plate on the mounting bracket 10, so that the silicon rod 30 is completely in contact with the connecting plate along the third direction C of the mounting bracket 10, so that the bonding of the silicon rod 30 to the connecting plate is more firm and reliable.

[0043] According to some embodiments of the utility model, a glue layer is provided on the connecting plate, and the glue layer is provided on a side surface of the connecting plate facing the silicon rod 30. A side surface of the third direction C of the mounting bracket 10 of the silicon rod 30 facing the connecting plate is suitable for bonding with the glue layer to fix the silicon rod 30 on the connecting plate. Therefore, the connecting plate is provided with a glue layer for bonding the silicon rod 30, so that the silicon rod 30 can be sliced ​​in the next step.

[0044] According to some embodiments of the utility model, it also includes: a workpiece plate, which is arranged on the side of the connecting plate away from the silicon rod 30, and the workpiece plate is connected to the connecting plate. A glue layer is arranged on the workpiece plate, and the glue layer is arranged on the side surface of the workpiece plate facing the connecting plate. The side surface of the connecting plate away from the silicon rod 30 along the thickness direction is bonded to the glue layer so that the connecting plate and the workpiece plate are fixedly connected. Therefore, the workpiece plate is convenient for moving the silicon rod 30 before slicing the silicon rod 30 after gluing the rod, and is convenient for carrying the silicon rod 30.

[0045] According to some embodiments of the present invention, Figure 2As shown, there are multiple clamping assemblies 20, and the multiple clamping assemblies 20 are arranged at intervals along the circumference of the mounting assembly. In this embodiment, the clamping assembly 20 includes: four first clamping members 21 and four second clamping members 22, the four first clamping members 21 are respectively abutted against the side surfaces of the four silicon rods 30 along the first direction A, and the four second clamping members 22 are respectively abutted against the side surfaces of the four silicon rods 30 along the second direction B, so as to press the silicon rods 30 against the partition 11. Thus, the multiple clamping assemblies 20 are arranged at intervals along the circumference of the mounting assembly to make the cooperation between the clamping assemblies 20 and the silicon rods 30 more stable, to prevent the silicon rods 30 from falling off when the clamping assemblies 20 move the silicon rods 30, and also to make the mounting bracket 10 position the silicon rods 30 more accurately.

[0046] Specifically, the process of bonding the silicon rod 30 is as follows:

[0047] An adhesive layer is provided on one side surface of the workpiece plate in the thickness direction, the connecting plate is placed flat on the adhesive layer, a weight is placed on the connecting plate to make the connecting plate and the workpiece plate fit completely, and the weight is removed after the adhesive layer is cured, and the connecting plate and the workpiece plate are fixedly connected. An adhesive layer is applied on one side surface of the connecting plate away from the workpiece plate in the thickness direction, and at the same time, a plurality of silicon rods 30 are placed in the receiving groove 14 of the mounting bracket 10 using an automated device, and the side stop of the clamping assembly 20 and the silicon rod 30 makes the silicon rod 30 and the partition 11 of the mounting bracket 10 fit tightly. The clamping assembly 20 further applies pressure to the silicon rod 30 to complete the integrated clamping of the silicon rod 30 and the mounting bracket 10, and the clamping assembly 20 clamps the silicon rod 30 and the mounting bracket 10 and moves them to the adhesive layer of the connecting plate, and the silicon rod 30 is bonded to the adhesive layer along the bottom surface of the third direction C. A weight is placed on the upper surface of the silicon rod 30 along the third direction C to make the silicon rod 30 completely fit with the connecting plate, and after the adhesive layer is pre-cured, the weight is removed, and the mounting bracket 10 is removed to obtain the bonded silicon rod 30. The bonded silicon rod 30 is left to stand for a period of time to allow the adhesive layer to completely cure, and a qualified silicon rod 30 that can be sliced ​​is obtained.

[0048] Therefore, during the bonding process of the silicon rods 30, the mounting bracket 10 plays a positioning role, and can simultaneously complete the positioning and bonding requirements of multiple silicon rods 30, avoiding bonding and slicing abnormalities caused by inaccurate positioning of the bonding rods, and improving the finished product yield of the silicon rod 30 slices.
