[0029] A glueing tooling with crystal orientation positioning, the structure of which is as Figures 1 - 4 shown, including a pallet 100, a crystal pallet 200, a resin plate 300 and a positioning assembly 400. The crystal pallet 200 is placed on the pallet 100, and the resin plate 300 is placed on the crystal pallet 200. A silicon rod 500 is placed on the top of the resin plate 300, and the resin plate 300 is used for supporting the silicon rod 500; the positioning assembly 400 includes a first positioning mechanism 410 and a second positioning mechanism 420. The first positioning mechanism 410 is installed on both left and right sides of the pallet 100 for glueing and positioning and fixing the crystal pallet 200, while the second positioning mechanism 420 is installed on both left and right sides of the crystal pallet 200 for glueing and positioning and fixing the resin plate 300. The first positioning mechanism 410 includes a worm 411, a plurality of worm wheels 412, a plurality of lead screws 413, a plurality of ball nuts 414 and two first positioning plates 415. The plurality of ball nuts 414 are arranged in parallel and correspondingly installed at the bottom of the two first positioning plates 415, and two ball nuts 414 corresponding to each other are screwed onto each lead screw 413. A corresponding worm wheel 412 is fixedly installed at the middle position of each lead screw 413, and each worm wheel 412 is meshed and connected with the worm 411. An adjusting bolt is arranged at the front end of the worm 411, so that when the adjusting bolt rotates to drive the worm 411 to screw, a plurality of worm wheels 412 meshed therewith rotate, so that a plurality of lead screws 413 fixedly installed with the worm wheels 412 rotate synchronously, so that two ball nuts 414 correspondingly arranged and screwed onto each lead screw 413 move relative to each other along the length direction of the lead screw 413, so that the first positioning plate 415 fixedly connected to the top of the ball nut 414 moves along the chute 101 on the pallet 100, thereby performing pasting and positioning on different-sized crystal pallets 200 placed on the pallet 100, preventing the crystal pallet 200 from being placed not at the center position and affecting the pasting of the crystal pallet 200; the second positioning mechanism 420 includes two second positioning plates 421, two fixing plates 422, four linkage rods 423 and two screw rods 424. Two corresponding linkage rods 423 are installed at the rear ends of the two second positioning plates 421, and the two linkage rods 423 pass through through holes provided on the fixing plates 422. A screw rod 424 is also screwed between the two fixing plates 422. Each screw rod 424 abuts against the rear end of the corresponding second positioning plate 421, so that when the two screw rods 424 are rotated, the two second positioning plates 421 are pushed to move relative to each other, and pasting and positioning are performed on the resin plate 300 placed on the crystal pallet 200.

[0030] During the process of positioning and pasting the silicon rod 500 with the pasting tooling, the operator places the crystal carrier plate 200 on the carrier plate 100, and a first positioning mechanism 410 is provided on the carrier plate 100. By rotating the adjusting bolt on the first positioning mechanism 410, the worm 411 fixedly connected to the adjusting bolt is driven to rotate, so that several worm wheels 412 engaged with the worm 411 rotate, so that several lead screws 413 fixedly installed with the worm wheels 412 rotate synchronously. The two corresponding ball nuts 414 screwed on each lead screw 413 move relative to each other along the length direction of the lead screw 413, so that the two first positioning plates 415 fixedly connected to the tops of several ball nuts 414 move along the sliding groove 101 on the carrier plate 100, and perform pasting positioning on different sizes of crystal carrier plates 200 placed on the carrier plate 100, preventing the crystal carrier plate 200 from being placed not at the center position, which affects the pasting of the crystal carrier plate 200. At the same time, the lifting rod provided at the top of the fixed rod moves downward, driving the nozzle installed on the support rod fixedly installed on the lifting rod to move downward, so that the nozzle sprays glue on the center position of the crystal carrier plate 200. After the spraying is completed, the operator places the resin plate 300 supporting the silicon rod 500 on the crystal carrier plate 200. Due to the influence of the size and width of the resin plate 300, it is necessary to align it with the center position of the crystal carrier plate 200. The operator fixes the second positioning plates 421 on both sides of the crystal carrier plate 200, so as to adjust the screw 424 on the second positioning plate 421, thereby pushing the second positioning plate 421 to move, so that the two relatively moving second positioning plates 421 position the resin plate 300 during pasting, and the nozzle sprays glue on the supporting groove on the surface of the resin plate 300, so that the silicon rod 500 is adhered to the resin plate 300, completing the gluing process of the silicon rod 500, and improving the gluing efficiency and gluing quality of the gluing tooling for the single crystal silicon rod 500.

[0031] As a preferred embodiment, please refer to Figure 2 and Figure 3 , several sliding grooves 101 are provided on the carrier plate 100, and each ball nut 414 is movably installed in each sliding groove 101, so that each ball nut 414 can move along the length direction of the corresponding sliding groove 101.

[0032] As a preferred embodiment, please refer to Figure 2 and Figure 4 , the second positioning plate 421 has an L-shaped structure, so that the side surface of the L-shaped second positioning plate 421 positions and fixes the resin plate 300, improving the positioning efficiency.

[0033] As a preferred embodiment, please refer to Figure 2 and Figure 4, A number of screw holes are provided on the crystal support plate 200, and a corresponding number of connection holes are provided on the fixing plate 422, so that the fixing plate 422 can be fixed to both sides of the top of the crystal support plate 200 through fixing bolts 425, making the fixing plate 422 on the second positioning mechanism 420 detachable. After the adhesive positioning and fixing are completed, it can be removed without affecting the use of the crystal support plate 200.

[0034] As a preferred embodiment, please refer to Figure 1 and Figure 2 , Both the first positioning plate 415 and the second positioning plate 421 are made of rigid plastic material to reduce the cost of the glued workpiece.

[0035] As a preferred embodiment, please refer to Figure 1 and Figure 2 , A butt plate 110 is also vertically provided at the rear end of the support plate 100 for aligning and positioning the tails of the crystal support plate 200, the resin plate 300, and the silicon rod 500, improving the gluing efficiency and gluing quality of the gluing tooling.

[0036] As a preferred embodiment, please refer to Figure 1 and Figure 2 , A lifting rod is movably installed inside the fixed rod fixedly installed at the rear end of the support plate 100. A horizontal support rod is installed at the top of the lifting rod. A nozzle is slidably installed on the support rod. The nozzle is used for spraying glue, and a glue delivery pipe is provided on the side of the nozzle for delivering glue, so that the glue is evenly sprayed on the crystal support plate 200 and the resin plate 300, improving the gluing quality of the silicon rod 500.

[0037] As a preferred embodiment, please refer to Figure 4 , The lead screw 413 is provided with threads with opposite rotation directions, so that the two ball nuts 414 screwed on the lead screw 413 can move relative to each other along the length direction of the lead screw 413.

[0038] The working principle of the utility model of a gluing tooling with crystal orientation positioning is as follows:

[0039] During the process of positioning and pasting the silicon rod 500 with the pasting tooling, the operator places the crystal carrier plate 200 on the carrier plate 100. The carrier plate 100 is provided with a first positioning mechanism 410. By rotating the adjusting bolt on the first positioning mechanism 410, the worm 411 fixedly connected to the adjusting bolt is driven to rotate, so that several worm wheels 412 engaged with the worm 411 rotate, so that several lead screws 413 fixedly installed with the worm wheels 412 rotate synchronously. The two ball nuts 414 correspondingly arranged and screwed on each lead screw 413 move relatively along the length direction of the lead screw 413, so that the two first positioning plates 415 fixedly connected to the tops of the several ball nuts 414 move along the sliding groove 101 on the carrier plate 100, and perform pasting positioning on the crystal carrier plates 200 of different sizes placed on the carrier plate 100, preventing the crystal carrier plate 200 from being placed not at the center position, which affects the pasting of the crystal carrier plate 200. At the same time, the lifting rod arranged at the top of the fixed rod moves downward, driving the nozzle installed on the support rod fixedly installed on the lifting rod to move downward, so that the nozzle sprays glue on the center position of the crystal carrier plate 200. After the spraying is completed, the operator places the resin plate 300 supporting the silicon rod 500 on the crystal carrier plate 200. Due to the influence of the size and width of the resin plate 300, it is necessary to align it with the center position of the crystal carrier plate 200. The operator fixes the second positioning plates 421 on both sides of the crystal carrier plate 200, so as to adjust the screw rod 424 on the second positioning plate 421, thereby pushing the second positioning plate 421 to move, so that the two relatively moving second positioning plates 421 position the resin plate 300 during pasting, and the nozzle sprays glue on the supporting groove on the surface of the resin plate 300, so that the silicon rod 500 is adhered to the resin plate 300, completing the gluing process of the silicon rod 500, and improving the gluing efficiency and gluing quality of the gluing tooling for the single crystal silicon rod 500.

[0040] The beneficial effects of a gluing tooling with crystal orientation positioning of the present utility model are as follows:

[0041] First, by arranging the first positioning mechanism 410 on the carrier plate 100, the worm 411 on the first positioning mechanism 410 rotates under the rotation of the adjusting bolt, thereby driving several worm wheels 412 screwed with the worm 411 to rotate, so that several lead screws 413 fixedly installed with the worm wheels 412 rotate synchronously, so that the two ball nuts 414 correspondingly arranged and screwed on each lead screw 413 move relatively along the length direction of the lead screw 413, so that the first positioning plate 415 fixedly connected to the top of the ball nut 414 moves along the sliding groove 101 on the carrier plate 100, thereby performing pasting positioning on the crystal carrier plates 200 of different sizes placed on the carrier plate 100, preventing the crystal carrier plate 200 from being placed not at the center position, which affects the pasting of the crystal carrier plate 200;

[0042] Second, by installing a detachable second positioning mechanism 420 on the crystal carrier plate 200, the two second positioning plates 421 on the second positioning mechanism 420 are used to paste and position resin plates 300 with different sizes and widths, preventing the resin plate 300 on which the silicon rod 500 is placed from not being in the middle position on the crystal carrier plate 200, thereby improving the pasting effect of the pasting tooling on the silicon rod 500.

At the same time, the scope of the utility model involved in the present application is not limited to the technical solutions formed by the specific combination of the above technical features, and should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept of the utility model.
