Description

Technical Field

[0001] The utility model relates to the technical field of silicon rod machining, in particular to an auxiliary tooling for gluing and splicing single crystal short round rods. Background Art

[0002] In the process of single crystal rod drawing and machining and grinding, the rough rod will be drawn according to the residual material in the single crystal furnace. The length of the final drawn single crystal rough rod is not uniform. When cutting by machining, the drawn rough rod will be cut into segments of fixed length according to production requirements. Due to the non-uniform length of the single crystal rough rod, short round rods that do not meet the production length requirements will always be produced after cutting and segmenting. Such short round rods will be spliced ​​with other suitable short round rods according to their own lengths by gluing to achieve the fixed length required by production. When gluing, the worker will apply AB glue to the flat end face of the short round rod, and then stand the end face of another short round rod to be spliced ​​on the other short round rod that has been glued, and fix it for a period of time.

[0003] Currently, if Figure 1 As shown, the longer short round stick is usually placed at the bottom, the shorter short round stick is placed at the top, and weights are placed on top of the shorter short round stick ( Figure 1 The method of adding weight to the spliced ​​adhesive surface (not shown) is however disadvantageous in that:

[0004] 1. The upper end surface (area) of the shorter round rod is not large enough, and the weight of the weight placed is limited, which will cause the shorter round rod to have insufficient weight and the weight of the counterweight, resulting in the glue being not strong and the glue on the glue surface being squeezed unevenly.

[0005] 2. Splicing upper and lower short round bars of different lengths requires different pressures, but the same weight of weight is placed each time, that is, it is impossible to apply corresponding pressure according to the length of the upper and lower short round bars;

[0006] 3. When splicing with glue, the upper and lower short round bars are prone to skew, causing the two short round bars to be out of axial alignment after splicing with glue. Utility Model Content

[0055] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the components and settings of specific examples are described below. Of course, they are only examples and are not intended to limit the present invention.

[0056] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0057] See also Figures 1 to 9 As shown, the utility model provides an auxiliary tooling for gluing and splicing single crystal short round bars, comprising:

[0058] A working platform 100 is provided on the ground and is used to place and support the short round bars to be spliced ​​with glue;

[0059] A centering mechanism 200 is used to lock and fix the adhesive parts of the two short round bars to achieve vertical coaxiality; and

[0060] The pressure mechanism 300 has a pressure plate 360;

[0061] The pressure plate 360 ​​can be lifted and lowered to press on the end surface of the upper short round rod, so as to apply a predetermined pressure to make the adhesive surfaces of the two short round rods closely fit together to achieve a secure bonding.

[0062] See also Figure 2 and Figure 7 As shown, the pressure mechanism 300 includes a frame 310, a pressure seat sleeve 320, a cross handle 330 and a first screw rod 340. The pressure seat sleeve 320 is fixedly mounted on the upper side of the middle part of the top beam 311 of the frame 310, and a screw sleeve 321 is provided for rotation. The cross handle 330 is fixedly sleeved on the upper end of the screw sleeve 321. The first screw rod 340 is threadedly connected with the screw sleeve 321, and its lower end freely passes through the middle part of the top beam 311 and is connected with the pressure plate 360. In specific operation, after the upper and lower short round bars with adhesive are locked coaxially in the centering mechanism 200, the operator holds the pressure plate 360 ​​with one hand and rotates the cross handle 330 with the screw sleeve 321 to rotate in the pressure seat sleeve 320 with the other hand. Since the pressure plate 360 ​​is held, the first screw rod 340 will not rotate with the screw sleeve 321 but can only rise and fall, thereby driving the pressure plate 360 ​​to rise and fall and press the end surface of the upper short round bar with a predetermined pressure. That is to say, by locking the centering mechanism 200, the upper and lower short round rods with glue can be coaxial, thereby preventing the short round rods from being skewed after gluing; at the same time, the pressure plate 360 ​​provided by the pressure mechanism 300 presses the upper short round rod by lifting and lowering, so that the glue surfaces of the two short round rods can be closely fitted, thereby ensuring the gluing quality of the short round rods.

[0063] See also Figure 3 and Figure 4 As shown, the seat sleeve 320 includes a hollow seat body 322 and a pressure cover 323. The seat body 322 is fixedly connected to the upper side of the middle part of the top beam 311 by screws, and the pressure cover 323 is sleeved on the lower end of the screw sleeve 321 and fixedly connected to the seat body 322 by screws. In this embodiment, the screw sleeve 321 is a self-lubricating copper screw sleeve; thus, the friction force and wear thereof are small when it rotates.

[0064] A flange 341 is provided at the lower end of the first screw rod 340. A pressure sensor 350 with a measuring range of 0 to 500 kg is connected between the flange 341 and the pressure plate 360. The pressure sensor 350 is electrically connected to a pressure display 370. The pressure display 370 is fixedly installed on the top beam 311 through an electric control box with a reset button. The predetermined pressure applied by the pressure plate 360 ​​to the upper short round bar can be measured by the pressure sensor 350 and displayed on the pressure display 370. The predetermined pressure is determined according to the length of the two short round bars. For short round bars of different lengths, after pressing the reset button of the electric control box and clearing the displayed value of the pressure display 370, the cross handle 330 can be turned to apply a predetermined pressure corresponding to the length of the upper short round bar through the pressure plate 360. That is, through the measurement of the pressure sensor 350 and the real-time monitoring of the pressure display 370, the corresponding pressure can be applied according to the length of the upper and lower short round bars, thereby avoiding problems such as weak glue and uneven extrusion of glue on the glue surface during splicing.

[0065] The pressure mechanism 300 further includes an anti-rotation sleeve 380 fixedly mounted on the lower side of the middle portion of the top beam 311. A flat square hole 381 is provided in the middle portion of the anti-rotation sleeve 380 (see Figure 6 As shown, the cross section of the first screw 340 is a flat square structure (see Figure 5 As shown), it is slidably connected with the flat square hole 381. When the cross handle 330 is rotated, the first screw rod 340 can only be lifted up and down driven by the rotating screw sleeve 321 due to the limitation of the flat square hole 381, thereby driving the pressure plate 360 ​​to lift up and down; in this way, the operator no longer needs to pinch the pressure plate 360 ​​by hand, freeing one hand of the operator and reducing the labor intensity.

[0066] See also Figure 7 As shown, the two ends of the top beam 311 are respectively connected to pillars 312 extending vertically downward, and the lower end of each pillar 312 is connected to a bottom beam 313 parallel to the length direction of the working platform 100, and each bottom beam 313 is connected to a counterweight block 314. The counterweight block 314 can increase the weight of the frame 310, improve the stability of the pressure mechanism 300, and effectively ensure that the bottom beam 313 will not leave the ground when the pressure plate 360 ​​presses the short round rod.

[0067] The bottom beam 313 is made of a square tube, and a counterweight rod 315 is inserted inside the bottom beam 313. In this way, the stability of the pressure mechanism 300 can be further improved.

[0068] Each bottom beam 313 has two ends connected to a universal caster 316 at the bottom side, wherein one universal caster 316 has a brake function. The pressure mechanism 300 can be moved to the working platform 100 (the workstation to be glued) through the universal caster 316.

[0069] See also Figure 8 and Fig. 9As shown, the centering mechanism 200 includes a first clamp 210 and a second clamp 220. The two ends of the first clamp 210 and the two ends of the second clamp 220 are respectively connected by a connecting kit consisting of a second screw 230, a column sleeve 240 and a plum handle nut 250, and a spring 260 is mounted on the second screw 230 between the two ends of the first clamp 210 and the two ends of the second clamp 220. When in use, first pass the second screw 230 through the two ends of the first hoop 210, put on the spring 260, and then put the first hoop 210 and the second hoop 220 on both sides of the glued parts of the two short round bars respectively and align them so that the second screw 230 passes through the two ends of the second hoop 220, and then put the column sleeve 240 on the second screw 230, screw on the plum handle nut 250 to tighten the first hoop 210 and the second hoop 220 to lock and fix the two short round bars, so that the two short round bars can be coaxial up and down under the pushing and guiding of the inner arc surface of the first hoop 210 and the second hoop 220. That is to say, through the pushing and guiding of the inner arc surface of the first hoop 210 and the second hoop 220, the two short round bars can be coaxial up and down, thereby avoiding skew.

[0070] In this embodiment, the first clamp 210 and the second clamp 220 are both made of acetal copolymer, so that when they are in direct contact with the short round rod, they will not cause pollution to the short round rod.

[0071] The specific working principle of the utility model is as follows:

[0072] 1. Preparation

[0073] First, stand the longer short round stick on the working platform 100, apply a certain amount of AB glue on the upper end surface thereof, and then stand the shorter short round stick and place its end surface on the end surface of the longer short round stick coated with glue.

[0074] 2. Pressurization

[0075] The centering mechanism 200 is used to lock and fix the glued parts of the two short round bars to ensure coaxiality; then the auxiliary tooling is moved to the working platform 100 so that the pressure plate 360 ​​is located directly above the short round bars. At this time, the cross handle 330 is turned, and the pressure plate 360 ​​will slowly contact the end face of the upper short round bar, the pressure sensor 350 begins to be subjected to force, and the pressure display 370 will display the current pressure.

[0076] 3. Maintain

[0077] At this time, according to the length of the short round rod, continue to rotate the cross handle 330 until the pressure display 370 displays the required pressure; according to the process requirements, keep it for a certain time.

[0078] The above embodiments are only preferred embodiments of the present utility model and are not limitations on the technical solutions of the present utility model. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present utility model.
