Description

Technical Field

[0001] This utility model relates to the field of engineering surveying and drilling technology, specifically a lifting platform with adjustable angle. Background Technology

[0002] Germanium wafers are produced by cutting a whole germanium rod into wafers of various thicknesses using a single-wire cutting method. However, during the blanking process, it is necessary to ensure that the end face of the germanium rod is parallel to the cutting line. In actual wire cutting operations, the parallelism is first measured using a dial indicator, and the runout deviation must be guaranteed to be no more than 0.01mm. However, the germanium rod is usually bonded to a graphite plate with sealing wax, and the graphite plate supports the germanium rod and is placed together on the wire cutting platform. At this time, the end face of the germanium rod cannot be guaranteed to be absolutely parallel to the cutting line. The existing process is to use a thin silicon steel sheet as a pad and then use a dial indicator for calibration. This is not only time-consuming and labor-intensive, but it is also difficult to guarantee an accuracy of 0.01mm. Considering that the slicing machine requires a large amount of cutting fluid, it is not convenient to use an electric adjustment method. Therefore, an auxiliary tool that can easily fine-tune the angle is needed.

[0003] Therefore, the technical problem to be solved in this case is: how to adjust the angle so that the cutting line is horizontal with the end face of the germanium rod. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a lifting platform with a finely adjustable angle. The lifting platform drives the driving block to approach the lifting block through a horizontal driving module. When the contact surface between the driving block and the lifting block is inclined, the driving block can push the lifting block to rise as it approaches the lifting block, thereby lifting the material to be cut and keeping the material to be cut in a horizontal state. During online cutting, this results in a flat cutting surface and improves the quality of the cut product.

[0005] The technical solution of this utility model is:

[0006] A lifting platform with adjustable angle includes a base and a lifting unit disposed on the base. The base is provided with a placement platform. The material to be cut is located on a substrate. The placement platform is used to place the substrate, and the outer edge of the substrate protrudes beyond the outer edge of the placement platform.

[0007] The lifting unit includes a support base connected to the base and a horizontal drive module set on the support base. The support base is provided with a lifting block that can move up and down. The lifting block is located below the substrate. The output end of the horizontal drive module is provided with a drive block. The top of the drive block is inclined. The bottom of the lifting block and the top of the drive block are in contact. The drive block is used to drive the lifting block to lift the substrate so that the material to be cut is kept horizontal.

[0008] Preferably, the support base is provided with vertically arranged guide columns, which are symmetrically arranged. The lifting block is slidably connected to the guide columns and can slide along the length of the guide columns.

[0009] Preferably, a first support member is provided on both sides of the support base, and a second support member is provided on both sides of the lifting block. The first support member and the second support member correspond one-to-one, and a first spring is provided between the first support member and the second support member.

[0010] Preferably, the horizontal drive module is a screw, and a fixed block is provided on the support base. The fixed block has a thread, and the horizontal drive module is screwed into the fixed block. One end of the drive block has a fixed groove, and the horizontal drive module passes through the fixed block. One end of the horizontal drive module is rotatably connected to the fixed groove. The rotation of the horizontal drive module can drive the drive block to move closer to or away from the lifting block.

[0011] Preferably, the support base is provided with a placement groove, and a first connecting block is provided at one end of the placement groove near the lifting block. A second connecting block is provided at the bottom of the drive block. The second connecting block is located in the placement groove. The first connecting block and the second connecting block are arranged horizontally. A second spring is provided between the first connecting block and the second connecting block. When the drive block moves close to the lifting block, the second connecting block compresses the second spring.

[0012] Preferably, the support base is provided with symmetrically arranged guide blocks, and the drive block is slidably connected between the symmetrically arranged guide blocks, and the drive block can slide along the length direction of the guide blocks.

[0013] Preferably, the guide block has a groove on the side near the drive block, the vertical cross-section of the drive block is an inverted T-shape, and the horizontal part of the drive block is located in the groove.

[0017] One of the above-described technical solutions of this utility model has at least one of the following advantages or beneficial effects:

[0018] This invention uses a horizontal drive module to drive a drive block closer to a lifting block. With the contact surface between the drive block and the lifting block being inclined, the drive block can push the lifting block upward as it approaches the lifting block, thereby lifting the material to be cut.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1

[0027] It should be noted that this embodiment takes the cutting of germanium rods as an example. Specifically, the germanium rods are bonded to a graphite plate with sealing wax, and then cut using wire cutting. Specifically, the thickness of the graphite plate is generally set to 20mm. When cutting the germanium rods, the cutting will reach the graphite plate, but the graphite plate will not be cut off at the same time. After cutting, the germanium rods are separated from the graphite plate by means of high temperature. The angle between the wire cutting line and the placement platform 11 is fixed. When the graphite plate with the germanium rods bonded to it is placed on the placement platform 11, there will be an angle shift. Therefore, the angle can be adjusted by this lifting platform to ensure that the cut surface of the germanium rod is flat when it is wire cut, thereby improving the product quality of the cut germanium rods.

[0028] Please see Figure 1-5 A lifting platform with adjustable angle is disclosed. The lifting platform includes a base 1 and a lifting unit 2 disposed on the base 1. The base 1 is provided with a placement platform 11. The external material to be cut 4 is located on a substrate 3. The placement platform 11 is used to place the substrate 3, and the outer edge of the substrate 3 protrudes beyond the outer edge of the placement platform 11. The lifting unit 2 includes a support base 21 connected to the base 1 and a horizontal drive module 22 disposed on the support base 21. The support base 21 is provided with a lifting block 23 that can move up and down. The lifting block 23 is located below the substrate 3. The output end of the horizontal drive module 22 is provided with a drive block 221. The top of the drive block 221 is a slope 2211. The bottom of the lifting block 23 contacts the top of the drive block 221. The drive block 221 is used to drive the lifting block 23 to lift the substrate 3 so that the material to be cut 4 is kept in a horizontal state.

[0029] In actual operation, substrate 3 is a graphite plate, and the material to be cut 4 is a germanium rod. The operator attaches the material to be cut 4 to substrate 3 with sealing wax, places substrate 3 with the attached material to be cut 4 on the placement table 11, and then measures the vertical offset distance of the material to be cut 4 using a dial indicator. Then, by placing support base 21 below the edge of substrate 3, the horizontal drive module 22 drives drive block 221 to approach lifting block 23. The contact surface between drive block 221 and lifting block 23 is an inclined slope 2211. Specifically, drive block 221 moves towards lifting block 23, and the contact surface between drive block 221 and lifting block 23 is an inclined slope 2211. Under the action of 11, the lifting block 23 will rise, thereby lifting the substrate 3, causing the material to be cut 4 to rise on the downward tilted side, and finally making the material to be cut 4 horizontal before cutting. Since the substrate 3 is not completely cut off during the cutting process, but only cut to a certain depth, that is, the substrate 3 is still a whole, so in subsequent cutting, multiple cutting operations can be completed by simply moving the cutting line of the wire cutting. By ensuring that the material to be cut 4 is horizontal during cutting, the flatness of the cut surface is ensured, and the quality of the cut material is improved.

[0030] Preferably, the support base 21 is provided with vertically arranged guide columns 211, the guide columns 211 are symmetrically arranged, and the lifting block 23 is slidably connected to the guide columns 211, and the lifting block 23 can slide along the length direction of the guide columns 211.

[0031] With the above design, the lifting block 23 is slidably connected to the guide post 211. When the driving block 221 pushes the lifting block 23 upward, the lifting block 23 will slide along the height direction of the guide post 211, thereby ensuring that the lifting direction is vertically upward. Furthermore, the symmetrically arranged guide posts 211 can further restrict the sliding direction of the lifting block 23.

[0032] Preferably, the support base 21 is provided with a first support member 217 on both sides, and the lifting block 23 is provided with a second support member 2111 on both sides. The first support member 217 and the second support member 2111 correspond one-to-one, and a first spring 24 is provided between the first support member 217 and the second support member 2111.

[0033] In the above design, during the process of the drive block 221 pushing the lifting block 23 upward, the first spring 24 will be in a stretched state. When it is necessary to reset, the first spring 24 will drive the lifting block 23 downward, which is beneficial to the easy reset of the lifting block 23 after cutting and is beneficial to subsequent use. It should be noted that in this embodiment, the first support member 217 is a bolt, the second support member 2111 is a bolt, and the first spring 24 is connected to the large end of the first support rod and the second support rod respectively, so as to prevent the first spring 24 from detaching from the first support rod and the second support rod. Specifically, the first support rod and the second support rod in this embodiment can be set as cylinders with two diameters respectively, and the first spring 24 can be connected to the large diameter end, which can prevent the first spring 24 from detaching.

[0034] Preferably, the horizontal drive module 22 is a screw, and the support base 21 is provided with a fixing block 212. The fixing block 212 is provided with a thread, and the horizontal drive module 22 is screwed into the fixing block 212. One end of the drive block 221 is provided with a fixing groove 2212. The horizontal drive module 22 passes through the fixing block 212, and one end of the horizontal drive module 22 is rotatably connected in the fixing groove 2212. The rotation of the horizontal drive module 22 can drive the drive block 221 to move closer to or away from the lifting block 23.

[0035] In this embodiment, the operator rotates the horizontal drive module 22 to drive the drive block 221 closer to or away from the lifting block 23. Specifically, rotating the horizontal drive module 22 clockwise moves the drive block 221 closer to the lifting block 23, while rotating it counterclockwise moves the drive block 221 away from the lifting block 23. During the rotation, the fixing block 212 enables a screw connection, thereby improving the stability of the horizontal drive module 22. Specifically, when rotating the horizontal drive module 22 clockwise, the fixing block 212, rotatably connected within the fixing groove 2212, pushes the drive block 221 towards the lifting block 23. When rotating the horizontal drive module 22 counterclockwise, the lifting block 23 descends under the action of the first spring 24, causing the drive block 221 to move away from the lifting block 23, thus ensuring that the fixing block 212 and the fixing groove 2212 remain in contact.

[0036] Specifically, this embodiment allows for fine-tuning of the angle. The horizontal drive module 22 is a screw, specifically implemented as follows: the horizontal drive module 22 has a specification of M12×0.5, and its outer peripheral wall has evenly distributed scale lines from 0 to 9. Specifically, each scale mark corresponds to 0.1 revolutions in the horizontal drive module 22. When the horizontal drive module 22 rotates one revolution, it moves forward or backward by 0.5mm. The drive block 221 and the lifting block 23 are connected... The inclined surface 2211 of the contact surface has a slope ratio of 1:10 for the driving block 221. That is, when the driving block 221 moves 1mm in the horizontal direction, it can push the lifting block 23 to rise by 0.1mm. Therefore, whenever the horizontal driving module 22 rotates by one scale, the horizontal driving module 22 moves forward by 0.05mm, which means that the driving block 221 moves horizontally by 0.05mm. When the driving block 221 moves 0.05mm closer to the lifting block 23, the lifting block 23 rises by 0.005mm, thereby achieving fine adjustment of vertical offset.

[0037] Preferably, the support base 21 is provided with a placement groove 213, and a first connecting block 214 is provided at one end of the placement groove 213 near the lifting block 23. A second connecting block 215 is provided at the bottom of the drive block 221. The second connecting block 215 is located in the placement groove 213. The first connecting block 214 and the second connecting block 215 are arranged horizontally. A second spring 25 is provided between the first connecting block 214 and the second connecting block 215. When the drive block 221 moves close to the lifting block 23, the second connecting block 215 compresses the second spring 25.

[0038] Through the above design, the second spring 25 is always in a compressed state. When the horizontal drive module 22 is rotated counterclockwise, the lifting block 23 will drive the drive block 221 to move away from the lifting block 23 under the action of the first spring 24. During this process, the second spring 25 is in a compressed and rebounding state. Finally, when the second connecting block 215 abuts against one end of the placement slot 213, the drive block 221 will return to the initial state, thus ensuring that it can be maintained in the initial state before and after each use, thereby improving accuracy. Specifically, the top of the lifting block 23 in the initial state is flush with the top of the placement platform 11.

[0039] Preferably, the support base 21 is provided with symmetrically arranged guide blocks 216, and the driving block 221 is slidably connected between the symmetrically arranged guide blocks 216, and the driving block 221 can slide along the length direction of the guide blocks 216.

[0040] In the above design, when the drive block 221 moves horizontally, it slides along the length direction of the guide block 216. The guide block 216 restricts the movement direction of the drive block 221, thereby ensuring that the drive block 221 can slide horizontally to lift the lifting block 23, and thus ensuring that the lifting block 23 can rise vertically to lift the substrate 3.

[0041] Preferably, the guide block 216 has a groove 2161 on the side near the drive block 221, the vertical cross section of the drive block 221 is an inverted T-shape, and the horizontal part of the drive block 221 is located in the groove 2161.

[0042] In this embodiment, the horizontal portion of the drive block 221 is located within the groove 2161, which can further restrict the movement direction of the drive block 221, so that the drive block 221 always slides in the horizontal direction.

[0043] Preferably, the base 1 is provided with a rotation drive unit, the output end of which is connected to the placement platform 11. The rotation drive unit is used to drive the placement platform 11 to rotate on the horizontal plane.

[0044] With the above design, the rotary drive unit can drive the placement table 11 to rotate on the horizontal plane, thereby driving the substrate 3 and the material to be cut 4 on the placement table 11 to rotate together, which makes it easier for the staff to operate.

[0045] Preferably, the rotary drive unit is a drive motor.

[0046] In the above design, the output end of the drive motor is connected to the placement platform 11, thereby driving the placement platform 11 to rotate. The drive motor is located below the placement platform 11 and is not shown in the figure.

[0047] Preferably, there are two lifting units 2, which are arranged on the adjacent side of the base 1.

[0048] In this embodiment, two lifting units 2 can be set. Specifically, since the maximum offset when the material to be cut 4 is placed on the placement platform 11 can only be any two pairs of opposite sides offset vertically, and the specific offset amount can be measured by a dial indicator, at this time, it is only necessary to place the lifting unit 2 directly below the material to be cut 4 that is offset downwards on the base, and adjust the vertical offset amount of the opposite side by lifting the side of the material to be cut 4 that is offset downwards until it is in a horizontal state. Therefore, at most two lifting units 2 are needed to adjust the material to be cut 4 to a horizontal state.

[0049] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
