[0036] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present utility model and be able to implement it, but the cited embodiments do not limit the present utility model.

[0037] Currently, mainly operators use auxiliary jigs to achieve the precise docking of the silicon rod and the hanging rod point positions, so as to realize the subsequent cutting of the silicon rod using multi-wire cutting technology. The existing method has a relatively high complexity in operation and low efficiency.

[0038] To solve the above problems, this embodiment provides a fork support mechanism and a silicon rod loading and unloading device for silicon rod loading and unloading.

[0039] Embodiment 1

[0040] Combined with Figure 1 and Figure 2 , this embodiment provides a fork support mechanism for silicon rod loading and unloading, including a support assembly 10, at least one swing assembly 20 provided on one side of the support assembly 10, and a fork 30 provided on the swing assembly 20. Among them, the swing assembly 20 is configured to rotate and adjust the rotation angle of the fork 30 at least in two directions to achieve precise adjustment of the position of the fork 30.

[0041] As Figure 2 shown, the support assembly 10 includes a horizontally arranged support plate 101 and support side plates 102 provided on both sides of the support plate 101. Specifically, there are the following several connection methods between the support plate 101 and the support side plates 102: First, pre-drill holes in the support plate 101 and the support side plates 102, and then use fastening components such as bolts, nuts, and washers to fasten them together; this method has a firm installation, is detachable, and is convenient for maintenance and replacement. Second, directly weld the support side plates 102 to both sides of the support plate 101 by welding; this connection method has a high connection strength but is not easily detachable, and it is difficult to make adjustments once the welding is completed. Third, provide mutually matching clamping parts and buckling parts on the support plate 101 and the support side plates 102, and insert the buckling parts of the support side plates 102 into the clamping parts of the support plate 101 to achieve clamping installation; this method is relatively simple to install, but the connection strength may be relatively weak. Fourth, use rivets to fix the support side plates 102 on the support plate 101. This connection method has a certain strength and sealing performance, but it is relatively difficult to disassemble. Those skilled in the art need to comprehensively consider various factors such as the specific use scenario, load-bearing requirements, disassembly requirements, and processing technology to select the connection method between the support plate 101 and the support side plates 102.

[0042] The swing assembly 20 is arranged at the end of the support plate 101 along the length direction of the support plate 101. The swing assembly 20 includes a first swing assembly 60 arranged at one end of the support plate 101 along the length direction of the support plate 101, and a second swing assembly 70 arranged on the first swing assembly 60. The pawl main body 301 is installed on the second swing assembly 70. The first swing assembly 60 is configured to swing and adjust the second swing assembly 70 around the first axis direction. The second swing assembly 70 is configured to swing and adjust the pawl 30 around the second axis direction. The first axis direction is parallel to the length direction of the support plate 101. The second axis direction is parallel to the width direction of the support plate 101. Therefore, the docking angle of the pawl 30 can be compound adjusted through the first swing assembly 60 and the second swing assembly 70, thereby improving the docking accuracy and docking efficiency. In this embodiment, swing assemblies 20 are arranged on both sides of the support assembly 10. Correspondingly, pawls 30 are also arranged on the swing assemblies 20 on both sides, so that bidirectional docking can be realized. That is, docking and supporting the silicon rod can be achieved in two directions. A possible embodiment is that the support assembly 10 can rotate, and thus, during the execution of one task, taking the silicon rod and placing the silicon wafer or taking the silicon wafer and placing the silicon rod can be realized. Obviously, Figure 1 In, the length direction of the support plate 101 refers to the direction where the longer side of the support plate 101 is located, and the width direction of the support plate 101 refers to the direction where the shorter side of the support plate 101 is located.

[0043] Specifically, in combination with Figures 3 to 5 , the first swing assembly 60 includes a first driving mechanism, a first eccentric wheel 603, a first swing main body 604 and a first rotating shaft 605. The first driving mechanism is arranged at the end of the support plate 101. The first eccentric wheel 603 is eccentrically arranged at the output end of the first driving mechanism. The first swing main body 604 is rotatably connected to the first rotating shaft 605. The first rotating shaft 605 is arranged at the end of the support plate 101 along the length direction of the support plate 101. Among them, the first driving mechanism includes a first motor 601 and a first speed reducer 602. The output end of the first motor 601 is connected to the input end of the first speed reducer 602. The output end of the first speed reducer 602 is fixedly connected to the first eccentric wheel 603. The first eccentric wheel 603 is configured to swing the first swing main body 604 around the axis direction of the first rotating shaft 605 under the drive of the first driving mechanism. Among them, the first eccentric wheel 603 can adopt a circular wheel structure eccentrically arranged at the output end of the first speed reducer 602, or a cam structure.

[0044] The first swing main body 604 includes a first rotating part 6041 and a first supporting part 6042 which are fixedly connected. The first rotating part 6041 is rotatably connected to the first rotating shaft 605. One side edge of the first rotating part 6041 horizontally extends along the length direction of the support plate 101 to form the first supporting part 6042. The second swing assembly 70 is installed on the first supporting part 6042.

[0045] The first rotating part 6041 is provided with a first rolling groove 606 from bottom to top. The first eccentric wheel 603 is located in the first rolling groove 606.

[0046] Furthermore, the first swing assembly 60 further includes a first bearing 610 coaxially connected to the first rotating shaft 605. The first bearing 610 provides stable support for the first rotating shaft 605, ensuring the position accuracy and concentricity of the first rotating shaft 605 during operation, preventing the first rotating shaft 605 from shifting, bending or vibrating, and ensuring that the first rotating shaft 605 can move accurately. The first rotating part 6041 is provided with a mounting hole (not marked in the figure) for cooperating with the first bearing 610.

[0047] Furthermore, a first shaft sleeve 609 is sleeved on the output end of the first speed reducer 602. The first shaft sleeve 609 prevents the output end of the first speed reducer 602 from directly contacting external components, reducing damages such as wear, scratches and corrosion, and extending the service life of the output end of the first speed reducer 602. At the same time, it helps with installation and accurately determines the position of the first eccentric wheel 603 that cooperates with it, ensuring the accuracy and stability of the installation.

[0048] The second swing assembly 70 includes a second driving mechanism, a second eccentric wheel 703, a second swing main body 704 and a second rotating shaft 705. The second driving mechanism is arranged on one side of the first swing main body 604. Specifically, the second driving mechanism is installed on one side of the first support portion 6042 of the first swing main body 604. The second eccentric wheel 703 is eccentrically arranged at the output end of the second driving mechanism. The second swing main body 704 is rotatably connected to the second rotating shaft 705. The second rotating shaft 705 is arranged along the width direction of the support plate 101 on the other side of the first swing main body 604. The second rotating shaft 705 is installed on the other side of the first support portion 6042. Among them, the second driving mechanism includes a second motor 701 and a second speed reducer 702. The output end of the second motor 701 is connected to the input end of the second speed reducer 702. The output end of the second speed reducer 702 is fixedly connected to the second eccentric wheel 703. The second eccentric wheel 703 is configured to swing the second swing main body 704 around the axis direction of the second rotating shaft 705 under the drive of the second driving mechanism. The second eccentric wheel 703 can adopt a circular wheel structure eccentrically arranged at the output end of the second speed reducer 702, or a cam structure.

[0049] Among them, the first support portion 6042 is provided with a first through hole 607 and a second through hole 608. The first through hole 607 is used for installing the second rotating shaft 705. The second through hole 608 is used for installing a part of the second speed reducer 702 and for the output end of the second speed reducer 702 to pass through.

[0050] The second swing body 704 includes a second rotating part 7041 and a second supporting part 7042 which are fixedly connected. The front end of the second rotating part 7041 extends along the width direction of the support plate 101 to form the second supporting part 7042. The surface of the second rotating part 7041 is in contact with the surface of the first supporting part 6042 (with a certain distance therebetween). The second rotating part 7041 is rotatably connected to the second rotating shaft 705. The second rotating part 7041 is provided with a second rolling groove 707 in the horizontal direction. The second eccentric wheel 703 is located in the second rolling groove 707. The supporting claw 30 is installed on the second supporting part 7042.

[0051] Further, the second swing assembly 70 further includes a second bearing 706 coaxially connected to the second rotating shaft 705. The second bearing 706 provides stable support for the second rotating shaft 705, ensures the position accuracy and concentricity of the second rotating shaft 705 during operation, prevents the second rotating shaft 705 from shifting, bending or vibrating, and ensures that the second rotating shaft 705 can move accurately. The second rotating part 7041 is provided with a mounting hole (not marked in the figure) for cooperating with the second bearing 706.

[0052] The supporting claw 30 includes a supporting claw body 301 and two supporting claw arms 302. The supporting claw body 301 is installed on the swing assembly 20. The supporting claw arms 302 are arranged on the side of the supporting claw body 301 away from the swing assembly 20 and are used to support the silicon rod 50.

[0053] Further, the supporting claw body 301 is detachably installed on the second swing body 704. The two supporting claw arms 302 are fixed on the same side of the supporting claw body 301. Herein, "detachably installed" is understood as that the supporting claw body 301 and the second swing body 704 can be fixedly connected by fastening elements such as bolts. When it is necessary to replace the supporting claw 30 according to the model of the pallet 40, when separating the supporting claw body 301 from the second swing body 704, the fastening elements can be loosened, and the supporting claw body 301 can be detached from the second swing body 704, so as to replace the supporting claw 30 of different models. Of course, the supporting claw 30 can also include only one supporting claw arm 302, which can be designed according to the pallet 40 to be carried.

[0054] In addition, the distance between the two supporting claw arms 302 can be designed according to the structure of the pallet 40 to be carried.

[0055] Further, the supporting claw arm 302 is provided with an anti - detachment groove 303 to prevent the pallet 40 from detaching from the anti - detachment groove 303 during the transportation of the silicon rod 50, resulting in damage to the silicon rod 50.

[0056] Furthermore, a chamfered portion 304 is provided at the end of the support pawl arm 302 away from the support pawl body 301. The chamfered portion 304 eliminates the sharp part of the edge of the support pawl arm 302, making it easier for the support pawl arm 302 to be inserted into the pallet 40, reducing the resistance and jamming during assembly, and improving the assembly efficiency and accuracy. At the same time, the chamfered portion 304 can reduce the possibility of the edge of the support pawl arm 302 being damaged by hitting the points of the hanging rod device.

[0057] The pallet 40 includes a panel 401 and a connecting plate 402. The connecting plate 402 is fixed to the top surface of the panel 401. The connecting plate 402 is transversely provided with a fork opening 4021 that cooperates with the support pawl arm 302. An adhesive with a certain viscosity is coated on the bottom surface of the panel 401 for bonding the silicon rod 50. When hanging the rod is required, after adjusting the docking position of the support pawl 30 and the pallet 40, the first swing assembly 60 and the second swing assembly 70 are adjusted to make the positive docking of the support pawl arm 302 and the fork opening 4021 of the pallet 40, so that when the support pawl arm 302 is inserted into the fork opening 4021, the pallet 40 and the silicon rod 50 can be supported.

[0058] The working principle of this embodiment is as follows:

[0059] The support and fork mechanism for silicon rod loading and unloading relies on a handling mechanism such as a robotic arm to move near the pallet 40 adhered with the silicon rod 50.

[0060] According to the specific position of the pallet 40, the first swing assembly 60 and / or the second swing assembly 70 are started to achieve the rotational angle adjustment of the support pawl 30 in at least two directions, so that the support pawl arm 302 of the support pawl 30 can just be inserted into the fork opening 4021 of the pallet 40.

[0061] Specifically, the first motor 601 and the first reducer 602 drive the first eccentric wheel 603 to rotate. The first eccentric wheel 603 causes the first swing body 604 to swing around the axis of the first rotating shaft 605, and at the same time drives the second swing body 704 to swing around the axis of the first rotating shaft 605, so that the support pawl 30 rotates and adjusts around the axis of the first rotating shaft 605.

[0062] The second motor 701 and the first reducer 602 drive the second eccentric wheel 703 to rotate. The second eccentric wheel 703 causes the second swing body 704 to swing around the axis of the second rotating shaft 705. At the same time, it drives the support pawl 30 to rotate and adjust around the axis of the second rotating shaft 705.

[0063] Embodiment 2

[0064] This embodiment provides a silicon rod loading and unloading device, which includes a handling mechanism and a fork mechanism for silicon rod loading and unloading as provided in Embodiment 1. The handling mechanism is connected to the fork mechanism for silicon rod loading and unloading. Among them, the handling mechanism can be a robotic arm composed of multiple joints and linkages that can perform precise movements and operations within a certain spatial range; it can also be multiple linear motion modules.

[0065] The working principle of this embodiment is basically the same as that of Embodiment 1, and will not be elaborated here.

[0066] It should be noted that the main design key point of the present utility model lies in the structural improvement of the fork mechanism for silicon rod loading and unloading. For other structures of the silicon rod loading and unloading device, such as the electrical connection part between the robotic arm and the fork mechanism for silicon rod loading and unloading, and the mechanical structure part of the robotic arm, they will not be elaborated one by one.

[0067] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
