[0038] The following refers to Figures 1 to 4Describe a crystal bar inspection table according to some embodiments of the present application.

[0039] The present application provides a crystal bar inspection table. As Figure 1 and Figure 2 shown, the crystal bar inspection table includes a frame 1, a support assembly 2 and a flipping assembly 3 provided on the frame 1. The crystal bar inspection table is provided with an inspection position. The crystal bar 10 to be measured can be transported to the inspection position. The flipping assembly 3 can pick up the crystal bar 10 from the inspection position and drive the crystal bar 10 to rotate a predetermined angle to achieve the flipping of the crystal bar 10.

[0040] The support assembly 2 can extend to the inspection position so that when the crystal bar 10 is transported to the inspection position, it can be first placed on the support assembly 2 to provide support for the crystal bar 10 through the support assembly 2, facilitating the flipping assembly 3 to pick up the crystal bar 10 from the inspection position; the support assembly 2 can also retreat from the inspection position to withdraw the support for the crystal bar 10 after the flipping assembly 3 picks up the crystal bar 10, providing an avoidance space for the subsequent flipping of the crystal bar 10.

[0041] In the actual inspection process, first extend the support assembly 2 to the inspection position, and use the automated truss in the crystal bar processing workshop to transport the crystal bar 10 to be measured from the blanking port of the crystal bar processing machine to the inspection position and place it on the support assembly 2; then use the flipping assembly 3 to pick up the crystal bar 10 and withdraw the support of the support assembly 2 for the crystal bar 10; finally, use the flipping assembly 3 to drive the crystal bar 10 to rotate a predetermined angle to complete the flipping of the crystal bar 10.

[0042] Therefore, through the crystal bar inspection table of the present application, the automatic flipping of the crystal bar can be realized, thus avoiding the influence on the crystal bar quality caused by the crystal bar falling during manual flipping; at the same time, the operator only needs to perform measurement work at the crystal bar inspection table, and the operator does not have to enter the blanking port of the crystal bar processing machine, thus avoiding the operator being pressed by the truss; at the same time, for multiple crystal bar processing machines in the machining workshop, the crystal bars at the blanking ports of each machine can be successively transported to the inspection position by the truss for measurement. The operator does not have to enter the blanking ports of each machine in turn to flip the crystal bars for measurement, thus effectively improving the automation degree of the crystal bar inspection process, reducing the work intensity of the operator, improving the work efficiency, and effectively avoiding the occurrence of batch quality accidents caused by operator missed inspections.

[0043] It should be noted that when the crystal bar 10 is placed on the support assembly 2 at the inspection position, the crystal bar 10 is placed horizontally, that is, the length direction of the crystal bar 10 extends along the horizontal direction. The flipping of the crystal bar 10 means rotating the crystal bar 10 by a predetermined inclination angle so that one end of the length direction of the crystal bar 10 is higher than the other end. For example, rotating the crystal bar 10 by 45° is convenient for the operator to measure the surface data of the crystal bar.

[0044] Regarding the support component 2, in an embodiment of the present application, preferably, in combination with Figure 2 and Figure 3 As shown, the support component 2 includes a stage 21 and a stage driving device 22. The stage 21 is disposed on one side of the first direction a of the detection position. The stage driving device 22 is used to drive the stage 21 to reciprocate along the first direction a so as to extend into or retreat from the detection position. Specifically, the opposite sides of the stage 21 in the second direction are respectively slidably connected to the frame 1 through guide rails. The guide rails are arranged along the first direction a, and the first direction a is perpendicular to the second direction. The stage driving device 22 is fixed to the frame 1, and the driving end of the stage driving device 22 is connected to the stage 21, so that the stage 21 can smoothly reciprocate along the first direction a under the drive of the stage driving device 22.

[0045] In this embodiment, there are two sets of support components 2. The stages 21 of the two sets of support components 2 are relatively disposed on both sides of the first direction a of the detection position. The two stages 21 can simultaneously extend toward the middle detection position or simultaneously retreat from the middle detection position under the drive of their respective stage driving devices 22. When the two stages 21 simultaneously extend into the detection position, the ingot 10 can be placed on the two stages 21 to provide support for the ingot 10 by the two stages 21 simultaneously. When the two stages 21 simultaneously retreat from the detection position, the two stages 21 withdraw the support for the ingot 10 and provide an avoidance space for the subsequent flipping of the ingot 10.

[0046] In this embodiment, preferably, first buffer pads 23 are provided on the stages 21 of the two sets of support components 2. The first buffer pads 23 are laid on the upper surface of one end of the stage 21 facing the detection position. When the ingot 10 is placed on the stage 21, the stage 21 contacts the ingot 10 through the first buffer pads 23, thereby avoiding damage to the surface of the ingot 10.

[0047] Preferably, the stage 21 is a stainless steel stage 21, and the material of the first buffer pads 23 is polyurethane, so as to avoid rusting of the stage 21 and contaminating the product.

[0048] Regarding the flipping component 3, in an embodiment of the present application, preferably, in combination with Figure 2 and Figure 4As shown, there are two sets of flipping components 3. Each set of flipping components 3 includes clamping plates 31. The two clamping plates 31 are relatively arranged on both sides of the first direction a of the detection position, and the two clamping plates 31 are respectively slidably mounted on the frame 1 along the first direction a through clamping plate seats 32, so that the two clamping plates 31 can move towards each other to clamp the ingot 10 at the detection position. At the same time, the two clamping plates 31 can rotate on the corresponding clamping plate seats 32, and the rotation axes of the two clamping plates 31 are both along the first direction a and coaxial. Thus, when the two clamping plates 31 clamp the ingot 10, rotating the two clamping plates 31 can drive the ingot 10 to rotate through the two clamping plates 31, so as to realize the automatic flipping of the ingot 10.

[0049] In this embodiment, preferably, as Figure 2 and Figure 3 shown, the two sets of flipping components 3 are arranged between the two carriers 21. An avoidance notch 24 is provided on one side of each carrier 21 facing the flipping component 3 for accommodating the flipping component 3 on the same side, so that the movement of the carrier 21 and the movement of the flipping component 3 will not interfere with each other.

[0050] In this embodiment, preferably, a clamping driving component is provided on the frame 1 for driving the two clamping plate seats 32 and the two clamping plates 31 to move towards each other or away from each other along the first direction a to clamp or release the ingot 10.

[0051] Specifically, as Figure 4 shown, the clamping driving component includes a clamping driving device 33, a first screw rod 34 and a second screw rod 35. The first screw rod 34 and the second screw rod 35 are both arranged along the first direction a, and the first screw rod 34 and the second screw rod 35 are both supported on the frame 1 through bearing seats, so that the first screw rod 34 and the second screw rod 35 can rotate around their own axes. The clamping driving device 33 is fixed on the frame 1. One end of the first screw rod 34 is connected to the driving end of the clamping driving device 33, so that the first screw rod 34 can rotate around its own axis under the drive of the clamping driving device 33. At the same time, the other end of the first screw rod 34 is connected to one end of the second screw rod 35 through a transmission component 36, so that the second screw rod 35 can rotate around its own axis under the drive of the first screw rod 34, and the second screw rod 35 has a rotation direction opposite to that of the first screw rod 34. Specifically, the transmission component 36 is a gear commutator.

[0052] Nut seats are provided on both of the two clamping plate seats 32. One nut seat is screwed to the first screw rod 34, and the other nut seat is screwed to the second screw rod 35. Thus, when the first screw rod 34 and the second screw rod 35 rotate in opposite directions under the drive of the clamping driving device 33, the two clamping plate seats 32 can move towards each other or away from each other, and further the two clamping plates 31 approach each other to clamp the ingot 10, or the two clamping plates 31 move away from each other to release the ingot 10.

[0053] In this embodiment, preferably, one of the two sets of the flipping assemblies 3 is an active flipping assembly, and its clamping plate 31 and clamping plate seat 32 are the active clamping plate and the active clamping plate seat, and the other set is a driven flipping assembly, and its clamping plate 31 and clamping plate seat 32 are the driven clamping plate and the driven clamping plate seat; for example, in Figure 4 the flipping assembly 3 on the right side is the active flipping assembly, and the flipping assembly 3 on the left side is the driven flipping assembly.

[0054] As Figure 4 shown, a flipping driving device 37 is provided on the active clamping plate seat, and the driving end of the flipping driving device 37 is connected to the active clamping plate. Thus, when the active clamping plate and the driven clamping plate clamp the ingot 10 and the active clamping plate rotates under the drive of the flipping driving device 37, the driven clamping plate and the ingot 10 can rotate synchronously therewith to realize the flipping of the ingot.

[0055] In this embodiment, preferably, an induction switch assembly 310 is provided on the active clamping plate seat, and an induction sheet is provided at the edge of the active clamping plate. When the active clamping plate rotates a predetermined angle to drive the ingot 10 to flip a predetermined angle, that is, when the ingot 10 flips in place, the induction sheet can just rotate with the active clamping plate to a position opposite to the induction switch assembly 310 to trigger the induction switch assembly 310, and the induction switch assembly 310 is communicatively connected to the flipping driving device 37 to control the flipping driving device 37 to stop working when the ingot 10 flips in place, so that the ingot 10 stays at the flipped position.

[0056] In this embodiment, preferably, as Figure 4 shown, second buffer pads 38 are laid on the clamping plates 31 of the two sets of flipping assemblies 3. When the two clamping plates 31 clamp the ingot 10, the two clamping plates 31 respectively contact the ingot 10 through their respective second buffer pads 38 to avoid damaging the surface of the ingot 10.

[0057] In this embodiment, preferably, as Figure 4 shown, a photoelectric assembly 39 is provided on the clamping plate seat 32 of at least one set of flipping assemblies 3. When the ingot 10 is placed at the detection position, the ingot 10 can be sensed by the photoelectric assembly 39, so as to determine whether an ingot 10 is placed at the detection position. The photoelectric assembly 39 is communicatively connected to the flipping assembly 3. When the photoelectric assembly 39 detects that an ingot 10 is placed at the detection position, it can send an instruction to the flipping assembly 3 to make the flipping assembly 3 clamp the ingot 10 and flip the ingot 10.

[0058] In an embodiment of the present application, preferably, as Figure 1 and Figure 2As shown in the figure, a water receiving tray 4 is provided below the detection position. The water receiving tray 4 is installed on the frame 1 through a water receiving support frame. Since the ingot 10 has liquid on it, when the ingot 10 is placed at the detection position, the water receiving tray 4 can receive the liquid dropped from the ingot 10 to prevent the liquid from dropping onto other components of the ingot detection table and causing the components to rust or be corroded. At the same time, when the ingot 10 accidentally drops, the water receiving tray 4 can also receive the ingot 10.

[0059] In this embodiment, preferably, as Figure 1 and Figure 2 shown, the above-mentioned first screw 34 and second screw 35 are located below the water receiving tray 4. A bellows cover 5 is sleeved on the first screw 34 and second screw 35. Both ends of the bellows cover 5 are respectively connected to two clamping plate seats 32. The bellows cover 5 is telescopic in the first direction a, so as not to affect the movement of the two clamping plate seats 32. At the same time, the first screw 34 and second screw 35 are covered by the bellows cover 5 to prevent the liquid carried on the ingot 10 from dropping onto the first screw 34 and second screw 35 and causing damage to the first screw 34 and second screw 35.

[0060] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
