Description

Technical Field

[0001] The utility model relates to the technical field of semiconductor production, in particular to a crystal rod transport carrier. Background Art

[0002] In the production process of monocrystalline silicon, after the single crystal is cut, it is often necessary to manually transfer the crystal rod. The commonly used methods are: manual handling, transportation by small transfer vehicles, etc. Manual handling is labor-intensive and inefficient. Small transfer vehicles are usually single-rod or double-rod trolleys. The number of crystal rods that can be transported at a time is small, and the limiting measures for the crystal rods are relatively simple. Due to their large mass and inertia, the crystal rods are easy to slip off the bracket and fall off during transportation, which may cause material loss at the least and injure workers at the worst, posing a great safety hazard to production.

[0036] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", etc. are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, features defined as "first", "second", etc. may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "multiple" means two or more.

[0038] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0039] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0040] Reference Figure 1-4 The embodiment of the utility model provides a crystal rod transport carrier, which includes a frame 1, a supporting member 2, a side stopper 3 and a fork positioning member 4. The frame 1 includes a plurality of storage layers of different heights, each storage layer is provided with a plurality of independent storage areas, the supporting member 2 is arranged in the storage area, and is used to support the crystal rod 16, and a plurality of side stops 3 are arranged on the outer periphery of the supporting member 2 to limit the lateral direction of the crystal rod 16 to prevent it from sliding or rolling. The storage areas are independent of each other and the side stops 3 are arranged, so that the plurality of crystal rods 16 on the carrier can be isolated from each other to prevent the crystal rods 16 from colliding with each other and causing damage during transportation; the plurality of fork positioning members 4 are arranged on different sides of the frame 1, so that when a plurality of the carriers are stacked side by side in the factory, the fork positioning member 4 on one side can always be unblocked, so as to facilitate the installation of the forks of the external transport equipment.

[0041] Since the crystal rod 16 has a large mass and a large inertia, the frame 1, the supporting member 2, and the side block 3 should all be made of a metal material with strong rigidity and strong bearing capacity. In order to prevent the crystal rod 16 from contacting the metal and causing quality defects, non-metallic insulators should be set on the supporting member 2 and the side block 3.

[0042] Reference Figure 1-2 and 4. In the present embodiment, the frame 1 is formed by welding metal plates and metal rods, and has two storage layers and ten storage areas. The supporting member 2 is located in the storage area, and includes a metal bottom plate 2-1 and two side plates 2-2 on both sides of the bottom plate 2-1. To facilitate loading and unloading of materials by the robot, the side plates 2-2 are configured along the length direction of the supporting member 2 as a first mounting portion 2-21 and a second mounting portion 2-22 of different heights. The first mounting portion 2-21 is located on both sides of the second mounting portion 2-22 and is higher than the second mounting portion 2-22. The first isolation pad 5 and the second isolation pad 6 are respectively installed on the first mounting portion 2-21 and the second mounting portion 2-22, and a blank separation area 7 is provided between the first isolation pad 5 and the second isolation pad 6. When working, the manipulator loads and unloads materials by clamping the silicon rods. The higher first mounting portion 2-21 can increase the degree of surrounding the side of the silicon rod and has better supporting stability. The shorter second mounting portion 2-22 and the blank separation area 7 between the first isolation pad 5 and the second isolation pad 6 provide operating space for the manipulator to extend under the silicon rod.

[0043] The above-mentioned first isolation pad 5 and second isolation pad 6 are both made of synthetic resin isolation pads. The first isolation pad 5 and the second isolation pad 6 are provided with a V-shaped supporting groove 8 with a continuous or separated bottom, which is used to support crystal rods 16 of different diameters. The crystal rods 16 of different diameters are surrounded to different degrees by the V-shaped supporting groove 8. Therefore, the placement stability of silicon rods of different diameters on the V-shaped supporting groove 8 is different. However, no matter whether the placement stability on the V-shaped supporting groove 8 is strong or weak, there are side blocks 3 to assist in limiting the lateral direction of the silicon rod to ensure the stability of the silicon rod on the transport carrier.

[0044] Taking into account the shape and placement direction of the silicon rod, the convenience of loading and unloading of the robot, etc., the side baffle 3 in this embodiment is configured to include a side baffle plate 3-1 and a side baffle rod 3-2. The side baffle plate 3-1 is located on both sides of the long end of the supporting member 2, and a third isolation pad 9 is provided on the plate surface close to the supporting member 2 to limit the long end of the silicon rod; the side baffle rod 3-2 is located on both sides of the wide end of the supporting member 2, and a fourth isolation pad 10 is sleeved thereon to limit the radial sides of the silicon rod. One side baffle plate 3-1 is provided along the long end of the supporting member 2 to meet most work requirements. A plurality of side baffle rods 3-2 can be evenly arranged on one side of the supporting member 2, and an appropriate gap is set between adjacent side baffle rods 3-2 so as not to block the operation of the robot to clamp the silicon rod.

[0045] The third isolation pad 9 and the fourth isolation pad 10 are both made of polyurethane isolation pads, and their shapes are respectively set to a plate shape and a cylinder shape according to the side baffle plate 3-1 and the side baffle rod 3-2 for easy installation.

[0046] The side baffles 3-1 and the side baffle rods 3-2 can be fixedly arranged on the outer side of the supporting member 2, or can be movably arranged. The side baffles 3-1 and the side baffle rods 3-2 of the former will have different degrees of change in the limiting effect on silicon rods of different lengths and diameters, while the side baffles 3-1 and the side baffle rods 3-2 of the latter can be adjusted in position according to the sizes of different silicon rods, so that the limiting effect is maintained at a uniform level.

[0047] In the latter scenario, refer to the attached Figure 3A sliding seat 11 slidably connected to the frame body 1 is provided at the bottom of the side baffle 3-1, and a screw 12 is passed through the sliding seat 11. The screw 12 extends along the length direction of the supporting member 2 and is rotatably connected to the frame body 1; a sliding seat 2 13 slidably connected to the frame body 1 is provided at the bottom of the side baffle rod 3-2, and a screw 2 14 is passed through the sliding seat 13. The screw 2 14 extends along the width direction of the supporting member 2 and is rotatably connected to the frame body 1. For ease of adjustment, a rotating handle 15 can be provided at the end of the screw 12 and the screw 2 14 extending out of the frame body 1. When the screw 12 is rotated, the slide 11 moves along the length direction of the screw 12 under the limiting effect of the frame 1 to get closer to or away from the supporting member 2. When the screw 2 14 is rotated, the slide 2 13 moves along the length direction of the screw 2 14 to get closer to or away from the supporting member 2 under the limiting effect of the frame 1 (for example, a slide groove is opened on the frame 1, and the inner wall of the slide groove is used to limit the side wall of the slide 11 so that it cannot rotate).

[0048] Since there are more loading areas on the carrier, the number of side baffles 3-1 and side baffle rods 3-2 is also large. In order to simplify the position adjustment operation, at least one set of positive and negative threads can be set on the screw 12, which are respectively connected to the slides 11 located on both sides of the supporting member 2. When the screw 12 is rotated, the slides 11 on both sides of the supporting member 2 in the length direction can be adjusted simultaneously; of course, for multiple supporting members 2 whose axes are on a straight line, the slides 11 on both sides can also be adjusted in position through a screw 12 with multiple sets of positive and negative threads.

[0049] Similarly, at least one set of positive-spinning threads and negative-spinning threads can be provided on the lead screw 14, which are respectively connected to the slide seats 13 located on both sides of the supporting member 2. When the lead screw 14 is rotated, the slide seats 13 on both sides of the supporting member 2 in the width direction can be adjusted simultaneously; of course, for multiple supporting members 2 arranged in parallel along the width direction, the slide seats 13 on both sides can also be adjusted in position by a lead screw 14 having multiple sets of positive-spinning threads and negative-spinning threads.

[0050] Reference Figure 1-2 The fork positioning member 4 includes two vertical plates 4-1 arranged opposite to each other. The two vertical plates 4-1 are symmetrical about the horizontal center line of the frame 1. The top of the vertical plates 4-1 is fixedly connected to the frame 1, and there is a spacing between the vertical plates 4-1 that adapts to the width of the fork, so that the fork can be quickly positioned and inserted to avoid deviation, which causes the frame 1 to be unstable due to uneven mass distribution after lifting. There can be one group of fork positioning members 4 on each side of the frame 1, or there can be multiple groups and they are located at different heights of the frame 1. When a group of fork positioning members 4 needs to be placed between different storage layers, in order to prevent the fork from accidentally touching the silicon rod when it is lowered and withdrawn, causing damage to the silicon rod, a horizontal plate 4-2 can also be set at the bottom of the vertical plate 4-1 to limit the bottom surface of the fork.

[0051] Compared with the prior art, the beneficial effects of the utility model are as follows: the transfer vehicle has multiple isolated loading areas, and the silicon rods are separated and limited by the side blocks 3, thereby improving the stability of the silicon rods during the transfer process, and multiple silicon rods can be transferred at a time by using ground bulls, forklifts, etc., thereby improving the transfer efficiency and reducing the labor intensity of workers.

[0052] The above are preferred implementations of the present utility model. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present utility model. These improvements and modifications should also be regarded as the protection scope of the present utility model.
