[0032] Example 1

[0033] This embodiment provides a crucible stand, such as Figure 1-Figure 5 As shown, it includes a support frame, a positioning frame is arranged on the upper part of the support frame, the positioning frame is used to place the crucible, the support frame supports the positioning frame and the crucible, the support frame includes an upper support frame, a lower support frame and a plurality of vertical connecting components located between the upper support frame and the lower support frame, the vertical connecting components connect the upper support frame and the lower support frame into a whole, a positioning frame is installed on the upper support frame, the positioning frame includes a crucible positioning grid frame located at the upper layer and support rods located at the lower layer, the crucible positioning grid frame is used to position the crucible, the crucible passes through the mesh holes of the crucible positioning grid frame, and is supported by the support rods of the lower layer. Preferably, in order to ensure the stability of the crucible support, two support rods are correspondingly arranged under each mesh hole.

[0034] The upper support frame is enclosed by an upper support tube, and the upper support tube is a square tube or a cylindrical tube. In order to facilitate the installation of the crucible positioning frame and the support rod, the upper support tube is a square tube.

[0035] Furthermore, the upper support frame is a square frame structure formed by four square tubes, and the two adjacent directional tubes are vertically welded and fixed at the ends. In this embodiment, the four square tubes are defined as a first square tube 1, a second square tube 2, a third square tube 3 and a fourth square tube 4, wherein the first square tube 1 and the second square tube 2 are arranged opposite to each other, and the third square tube 3 and the fourth square tube 4 are arranged opposite to each other.

[0036] The structure of the crucible positioning grid and the connection method with the upper support frame are the same as the technical solution disclosed in patent application CN110849145A. The crucible positioning grid includes a plurality of upper positioning rods 5 and a plurality of lower positioning rods 6. The upper positioning rods 5 and the lower positioning rods 6 are arranged perpendicularly and crosswise to form a plurality of mesh holes for accommodating the crucible.

[0037] Preferably, the upper positioning rod 5 and the lower positioning rod 6 are both cylindrical rods. It is understandable that the upper positioning rod 5 and the lower positioning rod 6 can also be cubic rods or rods of other structural forms.

[0038] The two ends of the upper positioning rod 5 are connected to the third square tube 3 and the fourth square tube 4 respectively, and the two ends of the lower positioning rod 6 are connected to the first square tube 1 and the second square tube 2 respectively.

[0039] Specifically, Figure 6As shown, fixing holes 7 matching the upper positioning rod 5 are provided on the inner tube walls of the third rectangular tube 3 and the fourth square tube 4. Since the upper positioning rod 5 is a cylindrical rod, the fixing holes 7 are circular holes. The two ends of the upper positioning rod 5 are respectively inserted into the circular holes on both sides, and the third rectangular tube 3 and the fourth square tube 4 are used for support.

[0040] like Figure 7-Figure 10 As shown, fixing holes 7 matching the lower positioning rod 6 are provided on the inner tube walls of the first square tube 1 and the second square tube 2. Since the lower positioning rod 6 is a cylindrical rod, the fixing holes 7 are circular holes, and the two ends of the lower positioning rod 6 are respectively inserted into the circular holes on both sides, and supported by the first square tube 1 and the second square tube 2.

[0041] In this embodiment, the ends of the upper positioning rod 5 and the lower positioning rod 6 pass through the fixing hole 7 and extend into the internal space of the square tube. They can rotate and move axially in the fixing hole 7 and both the upper positioning rod and the lower positioning rod can expand and contract due to heat.

[0042] The support rods 8 are arranged in a plurality of groups, and each group of support rods 8 is arranged below the mesh of the crucible positioning grid to support the crucible.

[0043] In this embodiment, each group is provided with two support bars 8, and the crucible is supported by the two support bars 8. It can be understood that each group can be provided with three or more support bars 8. The support bars 8 are cylindrical bars or rectangular parallelepiped bars, preferably cylindrical bars.

[0044] The two ends of the support rod 8 are respectively connected to the first square tube 1 and the second square tube 2. The inner tube walls of the first square tube 1 and the second square tube 2 are provided with long holes 9. The long axis of the long holes 9 is vertically arranged. The two ends of the support rod 8 are respectively inserted into the long holes 9 of the first square tube 1 and the second square tube 2 and fall into the bottom of the long holes 9, thereby realizing the support of the support rod 8 by using the first square tube 1 and the second square tube 2.

[0045] At the same time, in order to limit the support rod 8, the width of the long hole 9 matches the diameter of the support rod 8 and the bottom surface of the long hole 9 is an arc surface that matches the support rod 8.

[0046] An insertion hole 10 corresponding to the upper part of the long hole 9 is provided on the outer tube wall of the square tube on at least one side of the support rod 8, that is, an insertion hole 10 is provided on the outer tube wall of the first square tube 1 and / or the second square tube 2. When in use, the support rod 8 can pass through the insertion hole 10 to enter between the first square tube 1 and the second square tube 2 or be taken out from between the first square tube 1 and the second square tube 2.

[0047] Since the support rod 8 is a cylindrical rod, the insertion hole 10 is a circular hole matching the support rod 8 .

[0048] Furthermore, in order to reduce the processing cost, an insertion hole 10 is provided on the outer tube wall of the first square tube 1 , while no insertion hole is provided on the outer tube wall of the second square tube 2 .

[0049] When the support rod 8 needs to be installed, the support rod 8 is inserted from the insertion hole 10 of the first square tube 1 until the two ends of the support rod 8 correspond to the long holes 9 of the first square tube 1 and the second square tube 2 respectively, and then the support rod 8 falls under the action of its own gravity, and the two ends of the support rod 8 fall to the bottom surfaces of the long holes 9 of the first square tube 1 and the second square tube 2 respectively, thereby completing the installation of the support rod 8.

[0050] When the support bar 8 needs to be replaced, the support bar 8 is lifted up until the support bar 8 corresponds to the insertion hole 10, and the support bar 8 is moved horizontally so that the support bar 8 extends out of the insertion hole 10 on one side until the support bar 8 is taken out.

[0051] Compared with the crucible stand disclosed in patent application CN110849145A, the crucible stand of this embodiment can realize the disassembly and replacement of the support bar 8 by setting the long strip hole 9 and the insertion hole 10 matched with the support bar 8, and the operation is convenient and quick, avoiding the use of support bars that produce bending deformation, and overcoming the problems caused by the bending deformation of the support bar 8.

[0052] The lower support frame 11 is also formed by enclosing four lower support tubes, and the ends of adjacent lower support tubes are vertically welded and fixed.

[0053] Preferably, the lower support tube is also a square tube.

[0054] A vertical connection component is provided between the corners of the upper support frame and the lower support frame 11 and the middle positions of the lower support tubes corresponding to the first square tube 1 and the second square tube 2 .

[0055] Preferably, the vertical connection component is a vertical connection plate 12 , the top end of the vertical connection plate 12 is welded and fixed to the upper support frame, and the bottom end of the vertical connection plate 12 is welded and fixed to the lower support frame 11 .

[0056] A positioning component is also provided between the vertical connecting plate 12 located at the corner of the upper support frame and the lower support frame and the upper support frame. The positioning component is used to cooperate with the fork frame of the robot, which can facilitate better guidance and positioning of the fork frame, ensure that the crucible frame can be in the middle of the fork frame when in use, and ensure smooth operation.

[0057] The positioning component adopts a positioning plate 13, the bottom end of the positioning plate 13 is welded and fixed to the vertical connecting plate 12, and the top end of the positioning plate 13 is welded and fixed to the upper support frame. In this embodiment, the positioning plate 13 located on one side of the third square tube 3 is welded and fixed to the bottom surface of the third square tube 3 and has the same width as the third square tube 3, and the positioning plate 13 located on one side of the fourth square tube 4 is welded and fixed to the bottom surface of the fourth square tube 4 and has the same width as the fourth square tube 4.

[0058] The angle between the positioning plate 13, the vertical connecting plate 12 and the upper support frame matches the tooling on the robot fork. Preferably, the angle between the positioning plate 13, the vertical connecting plate 12 and the upper support frame is 45°, which meets the positioning requirements.

[0059] In another embodiment, the positioning component can also be a positioning block fixed between the vertical connecting plate 12 and the upper positioning frame, the positioning block has a positioning surface matching the tooling on the robot fork, and the angle of the positioning surface matches the tooling on the fork, preferably 45°.

[0060] Compared with the crucible stand disclosed in patent application CN110849145A, the crucible stand of this embodiment improves the connection form between the support rod and the upper support stand and adds a positioning component. The arrangement of the long hole 9 and the insertion hole 10 facilitates the disassembly and replacement of the support rod. The added positioning component ensures that the crucible stand can be in the middle of the fork stand during use. The remaining structures not described in detail are the same as those of the crucible stand disclosed in patent application CN110849145A and are not described in detail here.
