[0043] The position of the material seat positioning mechanism 20 is set according to process requirements. In this embodiment, the center line of the material seat positioning mechanism 20 along the first direction is aligned with the center line of the bottom plate 10 along the first direction. In some other embodiments of the present application, the material seat positioning mechanism 20 needs to cooperate with a subsequent grabbing manipulator, and the position of the material seat positioning mechanism 20 can be set at other positions of the bottom plate 10.

[0044] In this embodiment, the crystal bar fixing mechanisms 30 are symmetrically arranged on both sides of the center line of the material seat positioning mechanism 20 along the first direction. When the device is in use, the material seat assembly is installed on the material seat positioning mechanism 20 to complete the positioning of the material seat assembly. Then the crystal bar 60 is placed on the resin plate 50, and the clamping assemblies 31 of the crystal bar fixing mechanisms 30 are selectively rotated to the corresponding fixing angles according to the specifications of the crystal bar 60 to clamp both sides of the crystal bar 60 in the width direction. Because the crystal bar fixing mechanisms 30 are symmetrically arranged, the clamping assemblies 31 move towards each other during clamping, and the crystal bar 60 is pushed to align with the resin plate 50, that is, the centering is completed at the same time as the positioning of the crystal bar 60, thereby saving the operation of re-centering the crystal bar 60 and reducing the workload of the operator.

[0045] The technical scheme provided in this embodiment installs the material seat positioning mechanism 20 on the bottom plate 10, installs and fixes the material seat assembly through the protruding block 221, and completes the centering of the material seat assembly. The clamping assemblies 31 of the crystal bar fixing mechanisms 30 are provided with different fixing angles based on the specifications of the crystal bar 60, so as to stably clamp crystal bars 60 of different specifications, so that the device can be applied to production lines of crystal bars of various specifications. The clamping assemblies 31 on both sides are symmetrically arranged, so that the crystal bar 60 automatically completes the centering during clamping, the operation is simple and fast, the centering is accurate, and the production efficiency is improved.

[0046] In a specific embodiment, the universal crystal bar positioning device for multiple specifications provided by the present application is used in a single crystal production line of a certain specification. The material seat positioning mechanism 20 is installed at a set position of the bottom plate 10, the clamping assemblies 31 are pre-set to fixing angles matched with the specifications of the crystal bar, and are symmetrically installed on both sides of the center line of the material seat positioning mechanism 20 along the first direction. The material seat assembly is installed on the material seat positioning mechanism 20, and the center line thereof along the first direction is aligned with that of the material seat positioning mechanism 20. When the crystal bar 60 is placed on the resin plate 50 by the manipulator, it is located in the space between the clamping assemblies 31 on both sides. The clamping assemblies automatically clamp the crystal bar 60, and at the same time, the center line of the crystal bar 60 is aligned with that of the material seat assembly, so that the automatic centering of the crystal bar 60 is realized. After the centering of the crystal bar 60 is completed, the crystal bar is subjected to the sticking process and is removed from the positioning device. Then the above operation is repeated to position the next crystal bar 60. In this process, no manual assistance is required, and the work efficiency is greatly improved. At the same time, the positioning is more accurate, and the quality of the crystal bar 60 is ensured.

[0047] Based on the above technical solutions, this embodiment provides a specific implementation of the crystal rod fixing mechanism 30: as follows Figures 3-5 As shown, the crystal rod fixing mechanism 30 includes a positioning bracket 32 ​​and a clamping assembly 31. The adjusting rod 311 of the clamping assembly 31 is connected to the positioning bracket 32 ​​via a pin 3111, allowing the clamping assembly 31 to rotate around the pin 3111. The adjusting rod 311 and the positioning bracket 32 ​​are provided with several sets of matching limiting holes 3112. When the clamping assembly 31 rotates around the pin 3111, the limiting holes 3112 of the adjusting rod 311 and the limiting holes 3112 of the positioning bracket 32 ​​move relative to each other. When the clamping assembly 31 rotates to a certain fixed angle, one limiting hole 3112 of the adjusting rod 311 coincides with one limiting hole 3112 of the positioning assembly, and the adjusting rod 311 and the positioning assembly form a through hole. A limiting bolt 3113 is provided in the through hole 3112 to fix the adjusting rod 311. Specifically, when the clamping assembly 31 rotates to different angles, the clamping assemblies 31 of the opposite crystal rod fixing mechanism 30 move closer to each other, forming different gaps. Therefore, the fixing angle of the clamping assembly 31 is set according to the specifications of the crystal rod 60. By selectively rotating the clamping assembly 31 to a certain fixed angle, the clamping assembly 31 can be controlled to accurately clamp a crystal rod 60 of a certain corresponding specification. The clamping assemblies 31 on both sides of the crystal rod 60 form a clamping force of the same magnitude on the crystal rod 60, so that the crystal rod 60 always remains in a centered state and is not easy to deviate. At the same time, the magnitude of the clamping force is precisely controlled so as not to damage the crystal rod 60 and to securely fix the crystal rod 60.

[0048] Furthermore, the clamping assembly 31 also includes a positioning wheel 312, which is rotatably mounted on the adjusting rod 311. In this embodiment, the positioning wheel 312 is mounted to one end of the adjusting rod 311 via a wheel axle. The middle part of the adjusting rod 311 is provided with an insertion hole for mounting the pin 3111, and the other end is provided with a plurality of limiting holes 3112. The number and position of the limiting holes 3112 are set according to the specifications of the crystal rod 60 to be bonded. The insertion hole and the limiting holes 3112 are both provided on two opposite side end faces of the adjusting rod 311, and the two ends of the wheel axle of the positioning wheel 312 are connected to the side end faces. In contrast, the positioning bracket 32 ​​has an installation space for accommodating the adjusting rod 311, which can accommodate the adjusting rod 311 to rotate within it. The two opposite end faces of the positioning bracket 32 ​​are provided with insertion holes and limiting holes 3112 corresponding to the adjusting rod 311. The adjusting rod 311 is installed in the positioning bracket 32 ​​via a pin 3111. When it rotates around the pin 3111 to a fixed angle, the adjusting rod 311 and a set of limiting holes 3112 of the positioning bracket 32 ​​are connected. Then, a limiting bolt 3113 is set in the limiting hole 3112 to fix the adjusting rod 311 to the positioning bracket 32. During the process of placing the crystal rod 60 from top to bottom on the resin plate 50, the opposite positioning wheels 312 start to contact the crystal rod 60 and continue to roll downward until they abut against the two sides of the crystal rod 60, thereby achieving precise positioning of the crystal rod 60 in the width direction.

[0049] In this embodiment, the adjusting rod 311 and the positioning bracket 32 ​​are provided with two sets of corresponding limiting holes 3112, which are used for positioning the G12 and M10 specification crystal rods 60 respectively; in some other embodiments of this application, the adjusting rod 311 and the positioning bracket 32 ​​are provided with multiple sets of corresponding limiting holes 3112, which are used for centering and positioning crystal rods 60 of more specifications.

[0050] In this embodiment, there are two sets of crystal rod fixing mechanisms 30, which are distributed along the first direction; in other embodiments of this application, the number of crystal rod fixing mechanisms 30 is set according to the length of the crystal rod 60, and can be set to one or more sets.

[0051] Furthermore, in some specific embodiments of this application, this device is used when the crystal ingot 60 has shifted after initial positioning. For example... Figures 3-5 As shown, the crystal rod fixing mechanism 30 also includes a support block 33, which is fixed to the base plate 10; the positioning bracket 32 ​​is slidably connected to the support block 33 so that the positioning bracket 32 ​​can slide along the second direction; after the clamping assembly 31 clamps the crystal rod 60, it adjusts one or both fixed brackets to make them slide relative to the support block 33 along the second direction, thereby driving the crystal rod 60 to slide along the second direction, completing the precise adjustment of the position of the crystal rod 60, so that the crystal rod 60 is precisely centered.

[0052] Furthermore, in some specific embodiments of this application, this device is used to center and position crystal rods 60 that are not within the design specifications. If the fixed angle of the clamping assembly 31 cannot be adjusted to clamp the crystal rod 60 of that specification, then adjusting one or both fixed brackets to make them slide relative to the support block 33 in the second direction allows the positioning wheel 312 to abut against both sides of the crystal rod 60 to further clamp the crystal rod 60. Subsequently, the one or both fixed brackets are adjusted to complete the precise adjustment of the position of the crystal rod 60, so that the crystal rod 60 is precisely centered. When this device is used in a production line for crystal rods 60 of that specification, only one adjustment is needed to achieve continuous positioning and centering operations. The sliding connection between the positioning bracket 32 ​​and the support block 33 further expands the application range of this device, while ensuring accurate centering. No manual operation is required during continuous operation, which greatly improves production efficiency.

[0053] In a specific embodiment, the positioning bracket 32 ​​and the support block 33 are slidably connected as follows: the support block 33 is provided with a sliding groove 331, and the lower part of the positioning bracket 32 ​​is provided with a slider 321 that cooperates with the sliding groove 331; one end face of the support block 33 is provided with an adjustment hole 332, and the adjustment bolt passes through the adjustment hole 332 and is threadedly connected to the slider 321. The length direction of the slide groove 331 is consistent with the second direction, allowing the positioning bracket 32 ​​to slide along the second direction to adjust the distance between the two relative positioning blocks. The slider 321 is shaped to fit tightly against the side wall of the slide groove 331. The adjusting bolt is set along the second direction, with one end connected to the thread of the slider 321 and the other end passing through the adjusting hole 332 on the side wall of the slide groove 331 and fixed to the outer wall of the support block 33. When the positioning bracket 32 ​​is in the initial position, the slider 321 is fully engaged with the slide groove 331, and the side wall of the positioning bracket 32 ​​is flush with the side wall of the support block 33. When the adjusting bolt is rotated to move the slider 321 outward along the slide groove 331, one end of the slider 321 protrudes from the side wall of the support block 33.

[0054] Furthermore, in order to stably fix the positioning bracket 32 ​​to a certain relative position of the support block 33, the support block 33 is also provided with a fixing hole 333, and the fixing bolt passes through the fixing hole 333 to fix the slider 321.

[0055] In this embodiment, the fixing holes 333 are located on both sides of the adjusting holes 332 and are located on the side wall of the same support block 33. One end of the fixing bolt is connected to the slider 321, and the other end passes through the fixing holes 333 and is fixed to the side wall by a nut. After tightening the nut, the slider 321 can be fixed.

[0056] In some other embodiments of this application, the fixing hole 333 is provided on a different side wall than the adjustment hole 332, and the slider 321 is restricted from moving by pressing against it.

[0057] Furthermore, such as Figure 5 As shown, in order to enable the positioning bracket 32 ​​to slide stably relative to the support block 33, the opening width at the upper end of the groove 331 is smaller than the width at its lower end. That is, the cross-sectional shape of the groove 331 is set as a trapezoid that is narrower at the top and wider at the bottom. Correspondingly, the shape of the slider 321 is also constructed as a corresponding trapezoid, so that when the positioning bracket 32 ​​is in the initial state, it can wedge with the support block 33 and prevent the positioning bracket 32 ​​from detaching from the support block 33 from the upper end.

[0058] In this embodiment, as Figure 6 As shown, the material seat positioning mechanism 20 includes a material seat positioning block 21; the material seat positioning block 21 has support portions 211 at both ends for supporting the material seat assembly; the top of the support portion 211 is higher than the other parts of the material seat positioning block 21, so as to better adapt to material seats 40 of different shapes.

[0059] Furthermore, the material seat positioning mechanism 20 also includes a centering positioning block 22; the centering positioning block 22 is installed on the material seat positioning block 21 and is provided with the protrusion 221. When used for different material seats 40, different centering positioning blocks 22 can be disassembled and replaced to achieve positioning and fixing of the material seat 40 through the protrusion 221; furthermore, the top of the protrusion 221 is higher than the support part 211. Through the cooperation between the protrusion 221 and the support part 211, the installation position of the material seat 40 can be controlled more conveniently.

[0060] In this embodiment, the centering positioning block 22 is installed between the support portions 211 of the material seat positioning block 21. The centering positioning block 22 and the material seat positioning block 21 are aligned along the center line of the first direction. The protrusion 221 is disposed at the center line. A slot that cooperates with the protrusion 221 is provided at the bottom center of the material seat 40, so that when the material seat 40 is placed on the material seat positioning block 21, the part of the protrusion 221 enters the slot, thereby completing the positioning and limiting of the material seat 40. This ensures that the material seat 40 is centered and firmly fixed to the material seat positioning mechanism 20. The overall installation operation is simple and convenient.

[0061] In this embodiment, both the material seat positioning block 21 and the support block 33 are detachably mounted on the base plate 10.

[0062] In some embodiments of this application, after the material holder assembly is installed, the crystal ingot 60 is placed on the resin plate 50. The crystal ingot 60 can be aligned with the resin plate 50 first, and then the crystal ingot 60 can be clamped by the crystal ingot fixing mechanism 30 to complete the positioning of the crystal ingot 60. Alternatively, the crystal ingot 60 can be clamped by the crystal ingot fixing mechanism 30 first, and then the alignment of the crystal ingot 60 can be checked. If the crystal ingot is not aligned, the position of the positioning bracket 32 ​​can be adjusted to align the crystal ingot 60. The positioning and alignment operations of the crystal ingot 60 can be performed sequentially, or interspersed and repeated, to ultimately achieve accurate alignment and stable positioning of the crystal ingot 60.

[0063] This invention discloses a universal rod-sticking and positioning device for multiple specifications of crystal rods. Through the cooperation of the rod holder positioning block and the centering positioning block, precise centering of the rod holder and easy installation can be achieved. When applied to a production line with a fixed specification, the rod-sticking mechanism allows for precise and rapid centering and positioning operations without manual assistance, making it simpler and faster, and significantly improving production efficiency. The cooperation of the positioning bracket and the support block allows the device to be applied to more specifications of crystal rods, and the operation can be repeated multiple times. The overall structure of the device is simple and easy to control, with precise adjustment, reducing the workload of operators and improving work efficiency.
