Description

Technical Field

[0001] The present application relates to the technical field of artificial diamonds, and in particular to an automatic pre-assembly device for artificial diamond synthesis blocks and a pre-assembly method thereof. Background Art

[0002] Artificial diamond (industrial grade diamond) is increasingly used due to its high hardness and wear resistance. It is currently mainly used to make turning tools, saw blades, wire drawing dies, reamers, glass cutters, and drills (set on drill bits), while diamond powder is used as a high-grade abrasive material.

[0003] There are two main methods for artificially synthesizing diamonds: high-temperature and high-pressure methods and chemical vapor deposition methods. The high-temperature and high-pressure method is very mature and has formed an industry. Its method uses instantaneous static ultra-high-pressure and high-temperature technology, dynamic ultra-high-pressure and high-temperature technology, or a hybrid of the two to directly convert carbonaceous raw materials such as graphite from a solid or molten state into diamond. In the process of using graphite as a raw material for artificial diamond synthesis, the graphite column and related auxiliary materials (steel cups, pyrophyllite, heating plates, stainless steel, plugs) need to be pre-assembled according to certain rules. This pre-assembled part is called a synthesis block in the industry. Currently, the pre-assembly of the synthesis block is mainly done manually. For example, the transportation of the graphite column, the pushing of the auxiliary materials, and the pressure adjustment of the installation position between the graphite column and the auxiliary materials are all done manually. The entire pre-assembly of the synthesis block requires at least ten workers to complete.

[0004] However, in the process of implementing the existing technical solution, the applicant found that the above technology has at least the following technical problems: since the synthetic block has a large number of auxiliary materials and needs to be pre-installed with the graphite column in a certain regular order, it is inevitable that there will be omissions or wrong installations in the existing excessive manual intervention and pre-installation process. Once the auxiliary materials are missed or wrongly installed, the product will be directly scrapped. Summary of the Invention

[0005] In view of this, the embodiment of the present application provides an automatic pre-assembly device for artificial diamond synthesis blocks and a pre-assembly method thereof, which solves the technical problems in the prior art of manual pre-assembly that occur during the missing or incorrect installation of auxiliary materials, thereby leading to product scrapping.

The connection ends of the manipulators are movably connected to the pre-loading trays via transmission shafts. Driven by a rotary driver, the plurality of manipulators rotate along the auxiliary material installation sequence with the transmission shaft as the center.

[0013] Furthermore, a push key is used in the steel cup mounting hole and the talc mounting hole to replace the push rod. The push key is set to a frame shape, and a clamp is movably arranged on the inner wall of the push key, so that when the push driver drives the push key to move in the steel cup mounting hole and the talc mounting hole, the auxiliary material is fixed by the clamp.

[0014] Furthermore, a pre-clamping portion is provided on the disk surface of the pre-loaded disk, and a gravity sensor for obtaining the gravity of the graphite column is provided on the pre-loaded conveyor belt and directly below the pre-clamping portion on the disk surface, and the gravity sensor is communicatively connected to the PC end;

[0015] The PC sends instructions to the transmission driver that controls the movement of the pre-installed conveyor belt, the lifting driver that controls the lifting of the robot, and the clamping controller that controls the clamping of the robot based on the gravity signal fed back by the gravity sensor.

[0016] Furthermore, a pre-delivery portion is provided on the pre-loading tray, and an infrared sensor is provided on the pre-delivery portion to obtain a position signal of the manipulator rotating to the pre-delivery portion through the infrared sensor, and the position signal is fed back to the PC end, and the PC end sends an instruction to the clamping controller to control the manipulator to deliver the synthetic block onto the pre-loading conveyor belt.

[0017] Furthermore, an infrared sensor is provided on the pressure head, and the infrared sensor is communicatively connected with the PC end, the pressure driver, and the transmission driver. The infrared sensor obtains the position signal of the synthetic block on the pre-installed conveyor belt and feeds back the position signal to the PC end. The PC end sends instructions to the transmission driver and the pressure driver according to the position signal to respectively control the start and stop action of the pre-installed conveyor belt and the pressure adjustment action of the pressure head.

[0018] Furthermore, the pre-loading conveyor belt is configured as a loading conveyor belt and a unloading conveyor belt, the loading conveyor belt is arranged on the loading side of the pre-loading tray, the unloading conveyor belt is arranged on the unloading side of the pre-loading tray, and the pressure mechanism is arranged above the unloading conveyor belt.

[0019] The automatic pre-assembly device for artificial diamond synthesis blocks provided in the embodiments of the present application has at least the following technical effects or advantages:

[0020] 1. Compared with the previous implementation method of pre-assembling artificial diamond synthetic blocks by manual operation, the artificial diamond synthetic block automatic pre-assembly equipment of the embodiment of the present application is equipped with two pre-assembly trays, on which auxiliary material installation holes are respectively provided for workers to pre-store auxiliary materials, thereby replacing the tedious operation of manually holding auxiliary materials; a conveyor belt is provided to transport the graphite column to the bottom of the pre-assembly tray, thereby replacing the high-intensity work of manually carrying the graphite column; a mechanical arm controlled by a rotary drive is provided between the two pre-assembly trays to clamp the graphite column, thereby replacing the manual work of clamping the graphite column on the pre-assembly conveyor belt and delivering the graphite column to the corresponding auxiliary material installation hole;

[0021] Then, a pushing mechanism and a pushing driver are set in the auxiliary material installation hole, and the pushing mechanism is controlled by the pushing driver to push and install the auxiliary material on the graphite column to form a synthetic block, and the pressure head of the pressurizing mechanism is controlled by the pressurizing driver to further pressurize and adjust the synthetic block to adjust the assembly deviation between the two ends of the graphite column and the auxiliary material; in this way, the automatic pre-installation of the artificial diamond synthetic block is realized, and there is no need for excessive human intervention throughout the process. The number of personnel on the pre-installation assembly line of the synthetic block is reduced from 10 to 2, and only 2 people are needed to supplement the auxiliary material installation holes with auxiliary materials, which greatly reduces human interference and eliminates the troubles of missing or wrong installation of auxiliary materials in the previous manual pre-installation. Compared with manual pre-installation of synthetic blocks, it saves two-thirds of the time, thereby improving the pre-installation efficiency and quality.

[0022] 2. By arranging the steel cup mounting holes, pyrophyllite mounting holes, heating plate mounting holes, stainless steel plate mounting holes, and plug mounting holes in a clockwise order on the circumference of the pre-installed disk, the robot can clamp the graphite column and rotate it to the corresponding mounting hole. The corresponding auxiliary materials are installed at both ends of the graphite column in the set order, further avoiding the missing or wrong installation of auxiliary materials and ensuring the pre-installation quality of the composite block.

[0023] 3. By setting the number of auxiliary material mounting holes on the manipulator and the pre-installed disk to be the same, and setting the angle between two adjacent manipulators to be equal, it is ensured that each manipulator can accurately stop at the corresponding auxiliary material mounting hole position after rotation, thereby improving the coordination between the manipulator and the auxiliary material mounting hole and improving the pre-installation efficiency of the composite block.

[0024] 4. A gravity sensor is set on the conveyor belt and just below the pre-clamping part on the pre-loading disk surface. The gravity sensor is used to determine whether the graphite column has been transported to just below the pre-clamping part. The gravity sensor obtains the position signal of the graphite column and feeds it back to the PC. Then, the PC sends instructions to the transmission driver to control the pre-loading conveyor belt to stop, the lifting driver to control the robot to descend, and the clamping controller to control the robot to clamp the graphite column, thereby realizing automatic loading of the graphite column, reducing labor costs, and improving the pre-loading efficiency of the synthetic block.

[0025] A method for automatically pre-assembling an artificial diamond synthesis block, using the pre-assembling device to pre-assembly an artificial diamond synthesis block, at least comprising the following pre-assembly steps:

[0026] S1. Graphite columns are automatically loaded. The pre-loading conveyor belt transports the graphite columns to the bottom of the pre-clamping portion of the pre-loading tray. The gravity sensor feeds back the acquired gravity signal of the graphite columns to the PC end. The PC end sends instructions to the transmission driver, the lifting driver, and the clamping controller, so that the transmission driver controls the stopping of the pre-loading conveyor belt, the lifting driver controls the lowering of the manipulator, and the clamping controller controls the clamping end of the manipulator to clamp the graphite columns.

[0027] S2. Pushing and installing auxiliary materials: the rotary driver controls the manipulator to rotate in sequence along the steel cup mounting holes, pyrophyllite mounting holes, heating plate mounting holes, stainless steel plate mounting holes, and plug mounting holes arranged in the circumference of the pre-loaded disk. The pushing mechanisms installed in the steel cup mounting holes, pyrophyllite mounting holes, heating plate mounting holes, stainless steel plate mounting holes, and plug mounting holes push and install the auxiliary materials on the graphite column held by the manipulator under the control of the pushing driver to form a composite block.

[0028] S3: When the composite block is automatically unloaded, the manipulator grips the composite block and rotates to the pre-delivery portion of the pre-loading tray. The infrared sensor on the pre-delivery portion obtains the position signal of the manipulator and feeds the position signal back to the PC. The PC sends an instruction to the gripping and delivery controller to control the manipulator to deliver the composite block to the conveyor belt.

[0029] S4. Pressurize and adjust the synthetic block. The pressurizing mechanism is provided with a pressure head. The infrared sensor on the pressure head feeds back the acquired position signal of the synthetic block to the PC. The PC sends an instruction to the pressure driver to drive the pressure head to pressurize and adjust the synthetic block on the pre-installed conveyor belt to adjust the assembly deviation between the two ends of the graphite column and the auxiliary material.

[0030] The method for automatically pre-assembling an artificial diamond synthesis block provided in the embodiments of the present application has at least the following technical effects or advantages:

[0031] 1. Compared with the previous implementation method of pre-assembling artificial diamond synthetic blocks by purely manual operation, the embodiment of the present application adopts a pre-assembly device mainly composed of a pre-assembly tray, a pre-assembly conveyor belt, and a pressurizing mechanism to automatically pre-assembly artificial diamond synthetic blocks;

[0032] For example, the graphite column is transported to the bottom of the pre-loading disk through the pre-loading conveyor belt, so that the robot can descend and clamp the graphite column to complete the automatic loading of the graphite column; the rotary drive controls the robot to rotate to the corresponding mounting hole on the disk surface of the pre-loading disk, and then the push drive controls the pushing mechanism in the mounting hole to push and install the auxiliary material on the graphite column to form a composite block, completing the auxiliary material pushing and installation; through the coordination between the robot and the pushing mechanism in the mounting hole, the robot puts the composite block onto the conveyor belt to complete the automatic unloading of the composite block; finally, the pre-loading conveyor belt is used to control ... finally, the pre-loading conveyor belt is used to control the robot to rotate to the corresponding mounting hole on the disk surface of the pre-loading disk, and then the push drive controls the pushing mechanism in the mounting hole to push and install the auxiliary material on the graphite column to form a composite block, completing the auxiliary material pushing and installation; finally, the pre-loading conveyor belt is used to control the robot to rotate to the corresponding mounting hole on the disk surface of the pre-loading disk, and then the push drive controls the pushing mechanism in the mounting hole to push and install the auxiliary material on the graphite column to form a composite block, completing the auxiliary material pushing and installation; finally, the pre-loading conveyor belt is used to control the robot to rotate to the corresponding mounting hole on the disk surface of the pre-loading disk, The pressure head of the pressure mechanism above further adjusts the pressure on the synthetic block to adjust the assembly deviation between the two ends of the graphite column and the auxiliary materials; this realizes the automatic pre-installation of the artificial diamond synthetic block, and there is no need for excessive human intervention throughout the process. The number of personnel on the pre-installation assembly line of the synthetic block has been reduced from the original 10 to 2 people. Only 2 people are needed to replenish the auxiliary material installation holes, which greatly reduces human interference and avoids the trouble of missing or wrong installation of auxiliary materials in the previous manual pre-installation. Compared with the manual pre-installation of synthetic blocks, it saves two-thirds of the time, thereby improving the pre-installation efficiency and quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] In order to better understand the present technical solution, the present technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0052] First embodiment

[0053] like Figure 1-8 As shown, an automatic preloading device for synthetic diamond blocks is provided, comprising a preloading tray 10, a preloading conveyor belt 50, and a pressurizing mechanism 60. The preloading tray 10 is in the shape of a circular pan, with one preloading tray 10 positioned above each side of the preloading conveyor belt 50. The two preloading trays 10 are symmetrically arranged on either side of the preloading conveyor belt 50. The side of the preloading tray 10 feeding toward the conveyor belt is the loading side, and the side feeding away from the conveyor belt is the unloading side. The pressurizing mechanism 60 is positioned above the preloading conveyor belt 50 and on the unloading side of the preloading tray 10, thereby completing the assembly relationship between the preloading tray 10, the preloading conveyor belt 50, and the pressurizing mechanism 60.

[0054] According to the structural design of the pre-loaded disk 10, a plurality of auxiliary material mounting holes 101 are provided on the circumference of the disk surface of the pre-loaded disk 10, and different auxiliary materials are stored in the plurality of auxiliary material mounting holes 101. In the embodiment of the present application, it is preferred to open seven auxiliary material mounting holes 101 on the circumference of the disk surface of the pre-loaded disk 10, and the seven auxiliary material mounting holes 101 are equidistantly arranged around the center of the circle of the pre-loaded disk 10 (the equidistant arrangement of the seven auxiliary material mounting holes 101 means that the seven auxiliary material mounting holes 101 are equidistant from the center of the circle of the pre-loaded disk 10, the margins between each adjacent two auxiliary material mounting holes 101 are equal, and the angles between each adjacent two auxiliary material mounting holes 101 are equal). The seven auxiliary material mounting holes 101 are used to store steel cups, talc, heating plates, stainless steel plates, and plugs respectively. When the auxiliary materials on the auxiliary material mounting holes 101 are almost consumed, only two people are required to replenish the auxiliary materials.

[0055] A transmission shaft 30 is provided between the two pre-loading disks 10, and both ends of the transmission shaft 30 are movably connected to the pre-loading disks 10, and a plurality of manipulators 20 are provided on the transmission shaft 30. Specifically, in the embodiment of the present application, seven manipulators 20 are preferably provided, and the connection ends of the seven manipulators 20 are arranged equidistantly around the transmission shaft 30 (the equidistant arrangement of the seven manipulators 20 means that the seven manipulators 20 are arranged around the transmission shaft 30 as the center, and the angles between each two adjacent manipulators 20 are equal), so that the connection ends of the seven manipulators 20 are movably connected to the pre-loading disks 10 through the transmission shaft 30. The end of the manipulator 20 away from the transmission shaft 30 is a clamping end, and the clamping end of the manipulator 20 is used to clamp the graphite column on the pre-loading conveyor belt 50.

[0056] The seven manipulators 20 are controlled by a rotary drive, which can be motorized. Driven by the rotary drive, the seven manipulators 20 rotate about the drive shaft 30 in the direction of the auxiliary material installation sequence (rotation in the direction of the auxiliary material installation sequence refers to the manipulators 20 rotating along the surface of the pre-loaded tray 10 and the installation sequence of the steel cup, pyrophyllite, heating plate, stainless steel plate, and plug). Because the distance between the auxiliary material installation holes 101 and the drive shaft 30 is equal to the length of the manipulators 20, the gripping ends of the manipulators 20 can extend to the auxiliary material installation holes 101 during rotation, allowing the gripping ends of the seven manipulators 20 to sequentially clamp and deliver the graphite columns to the corresponding auxiliary material installation holes 101.

[0057] The auxiliary material mounting hole 101 can be configured as either a cylindrical or rectangular hole. A pushing mechanism and a pushing drive are located within the auxiliary material mounting hole 101. The pushing drive can be a motor or a pneumatic cylinder. In practice, the auxiliary material mounting hole 101 is provided with a groove and a slide rail for the pushing mechanism to move axially within the auxiliary material mounting hole 101. Under the control of the pushing drive, the pushing mechanism reciprocates along the axial direction of the auxiliary material mounting hole 101, controlling the conveying direction of the auxiliary material. Thus, the pushing mechanism pushes the auxiliary material stored in the auxiliary material mounting hole 101 toward the graphite column, where it is mounted to form a composite block.

[0058] The pressurizing mechanism 60 is mounted above the pre-installed conveyor belt 50 via a mounting frame. The pressurizing mechanism 60 is provided with two oppositely arranged pressure heads 601. A pressure driver, preferably a pneumatic cylinder, is provided on the mounting frame to control the pressing action of the pressure heads 601. The preliminarily installed composite block is placed on the conveyor belt at the unloading side of the pre-installed tray 10 by the robot 20. When the composite block is transported by the conveyor belt to the bottom of the pressurizing mechanism 60 and located between the two pressure heads 601, the auxiliary materials installed at both ends of the graphite column are respectively facing the two pressure heads 601 of the pressurizing mechanism 60. Under the control of the pressure driver, the two pressure heads 601 are pressed relative to each other to adjust the pressure of the composite block (the preliminarily pre-installed auxiliary materials at both ends of the graphite column).

[0059] The automatic pre-assembly device for artificial diamond synthesis blocks provided in the embodiments of the present application has at least the following technical effects or advantages:

[0060] Compared with the previous implementation method of pre-assembling artificial diamond synthetic blocks by manual operation, the artificial diamond synthetic block automatic pre-assembly equipment of the embodiment of the present application is provided with two pre-assembly trays 10. The two pre-assembly trays 10 are provided with auxiliary material installation holes 101 for workers to pre-storage auxiliary materials, thereby replacing the tedious operation of manually holding auxiliary materials; a pre-assembly conveyor belt 50 is provided to transport the graphite columns to the bottom of the pre-assembly tray 10, thereby replacing the high-intensity work of manually carrying the graphite columns; a manipulator 20 controlled by a rotary driver is provided between the two pre-assembly trays 10 to clamp the graphite columns, thereby replacing the manual operation of clamping the graphite columns on the pre-assembly conveyor belt 50 and delivering the graphite columns to the corresponding auxiliary material installation holes 101;

[0061] Then, a pushing mechanism and a pushing driver are set in the auxiliary material installation hole 101, and the pushing driver controls the pushing mechanism to push and install the auxiliary material on the graphite column to form a synthetic block, and the pressure driver controls the pressure head 601 of the pressurizing mechanism 60 to further pressurize and adjust the synthetic block to adjust the assembly deviation between the two ends of the graphite column and the auxiliary material; thereby, automatic pre-installation of artificial diamond synthetic blocks is realized, and no excessive human intervention is required throughout the process. The number of personnel on the pre-installation assembly line of the synthetic block is reduced from 10 to 2, and only 2 people are required to supplement the auxiliary material installation hole 101 with auxiliary materials, which greatly reduces human interference and avoids the trouble of missing or wrong installation of auxiliary materials in the previous manual pre-installation. Compared with manual pre-installation of synthetic blocks, it saves two-thirds of the time, thereby improving the pre-installation efficiency and quality.

[0062] like Figure 1 As shown, a pre-clamping portion 102 is provided on the disk surface of the pre-loaded disk 10 and near the bottom edge of the pre-loaded disk 10. The pre-clamping portion 102 is the position where the clamping end of the manipulator 20 stops when it rotates to the lowest point, and is also the position where the manipulator 20 starts to descend to clamp the graphite column.

[0063] A gravity sensor for sensing the gravity of the graphite column is provided on the pre-loaded conveyor belt 50 and directly below the pre-clamping portion 102 of the disk. When the graphite column on the pre-loaded conveyor belt 50 is transported to the position where the gravity sensor is installed, the gravity sensor obtains the gravity signal of the graphite column. The gravity sensor is communicated with the user's PC.

[0064] In actual application, the start and stop of the pre-loaded conveyor belt 50 is controlled by the transmission driver, the lifting and lowering action of the manipulator 20 is controlled by the lifting driver, and the clamping and delivery action of the manipulator 20 is controlled by the clamping and delivery controller. The transmission driver can select a motor, and the lifting driver and the clamping and delivery controller can select a cylinder. The user's PC sends instructions to the transmission driver, the lifting driver, and the clamping and delivery controller based on the gravity signal fed back by the gravity sensor. When the graphite column is transported by the pre-loaded conveyor belt 50 to the bottom of the pre-clamping part 102 and the gravity sensor obtains the gravity of the graphite column, the PC receives the gravity signal of the gravity sensor and sends an instruction to control the transmission driver to control the pre-loaded conveyor belt 50 to stop the conveying action, the lifting driver controls the manipulator 20 to descend to the set position, and the clamping and delivery controller controls the clamping end of the manipulator 20 to clamp the graphite column on the pre-loaded conveyor belt 50 below the pre-loaded clamping part, thereby realizing the automatic loading of the graphite column, reducing labor costs, and improving pre-loading efficiency.

[0065] like Figure 1 、 3 As shown in Figures 6 and 7, based on the type of auxiliary materials to be stored in the mounting holes on the pre-loaded tray 10, the auxiliary material mounting holes 101 include at least a steel cup mounting hole 1011, a pyrophyllite mounting hole 1012, a heater plate mounting hole 1013, a stainless steel plate mounting hole 1014, and a plug mounting hole 1015, which are arranged in a clockwise order along the circumference of the pre-loaded tray 10. Based on the shape of the auxiliary materials and the installation requirements, the pyrophyllite mounting hole 1012 is formed as a rectangular hole on the surface of the pre-loaded tray 10, while the steel cup mounting hole 1011, the heater plate mounting hole 1013, the stainless steel plate mounting hole 1014, and the plug mounting hole 1015 are formed as cylindrical holes on the surface of the pre-loaded tray 10. The steel cup mounting hole 1011, the pyrophyllite mounting hole 1012, the heater plate mounting hole 1013, the stainless steel plate mounting hole 1014, and the plug mounting hole 1015 are holes formed by penetrating both sides of the pre-loaded tray 10.

[0066] In this way, by arranging the steel cup mounting hole 1011, talc mounting hole 1012, heating plate mounting hole 1013, stainless steel plate mounting hole 1014, and plug mounting hole 1015 in a clockwise direction on the circumference of the disk surface of the pre-installed disk 10, the robot 20 can clamp the graphite column and rotate it to the corresponding mounting hole, and install the corresponding steel cup, talc, heating plate, stainless steel plate, plug and other auxiliary materials at both ends of the graphite column in a set order. In actual application, the auxiliary materials such as heating plate, stainless steel plate, and plug are in the hole for installing talc, which further avoids missing or wrong installation of the auxiliary materials and ensures the pre-installation quality of the synthetic block.

[0067] According to the above description, the number of the manipulators 20 is set to seven, and the number of the auxiliary material mounting holes 101 is also set to seven, so that the number of manipulators 20 is the same as the number of auxiliary material mounting holes 101. According to the design features that the angle between each two adjacent auxiliary material mounting holes 101 is equal, the angle between each two adjacent manipulators 20 is equal, and the distance between the auxiliary material mounting holes 101 and the transmission shaft 30 is equal to the length of the manipulator 20; when one of the manipulators 20 rotates to a corresponding auxiliary material mounting hole 101, the remaining manipulators 20 will also rotate to the corresponding auxiliary material mounting hole 101, thereby ensuring that each manipulator 20 has a corresponding auxiliary material mounting hole 101 for pre-installing auxiliary materials. After each manipulator pushes the auxiliary material to the set position and completes the installation, it will then rotate synchronously to the next set point.

[0068] In this way, by setting the number of auxiliary material mounting holes 101 on the manipulator 20 and the pre-installed disk 10 to be the same, and setting the angle between two adjacent manipulators 20 to be equal, it is ensured that each manipulator 20 can accurately stop at the corresponding auxiliary material mounting hole 101 position after rotation, thereby improving the coordination between the manipulator 20 and the auxiliary material mounting hole 101 and improving the pre-installation efficiency of the synthetic block.

[0069] like Figure 4 、 5 As shown, in the embodiment of the present application, the pushing mechanism provided uses an L-shaped push rod 40. Therefore, an L-shaped push rod 40 and a pushing driver are respectively provided in the steel cup mounting hole 1011, the pyrophyllite mounting hole 1012, the heating plate mounting hole 1013, the stainless steel plate mounting hole 1014, and the plug mounting hole 1015. The straight section of the L-shaped push rod 40 (the straight section refers to the upper end of the L-shaped push rod 40, or the end connected to the slide rail in the auxiliary material mounting hole 101) is connected to the pushing driver, and the curved section of the L-shaped push rod 40 (the curved section refers to the lower end of the L-shaped push rod 40, or the end that directly pushes the auxiliary material to move) extends toward the middle of the mounting hole, and the end of the curved section of the L-shaped push rod 40 faces the auxiliary material pushing direction.

[0070] Therefore, when the push driver drives the straight section of the L-shaped push rod 40 to move along the slide rail direction in the auxiliary material installation hole 101, the curved section of the L-shaped push rod 40 pushes the auxiliary material in the auxiliary material installation hole 101 toward the hole mouth, and finally installs the auxiliary material on the graphite column.

[0071] like Figure 1As shown, a pre-dropping portion 103 is provided on the pre-loading tray 10 and near the unloading side of the pre-loading tray 10. The pre-dropping portion 103 is the position where the manipulator 20 drops the pre-preloaded composite blocks onto the pre-loading conveyor belt 50. In order to accurately control the timely delivery action of the manipulator 20, an infrared sensor is provided on the pre-dropping portion 103 to obtain a position signal of whether the manipulator 20 has rotated to the pre-dropping portion 103, and the infrared sensor feeds back the obtained position signal to the user's PC. The user's PC sends an instruction to the clamping controller to control the manipulator 20 to drop the composite blocks onto the set position of the pre-loading conveyor belt 50. Then, the pre-loading conveyor belt 50 transports the composite blocks to the next pressurizing station. In this way, the automated unloading of composite blocks is achieved, which further reduces labor costs and improves pre-loading efficiency.

[0072] like Figure 7 、 8 As shown, an infrared sensor is installed on the pressure head 601 of the pressurizing mechanism 60. This infrared sensor is in communication with the PC, the pressure driver, and the transmission driver. The infrared sensor receives a position signal to determine whether the composite block on the pre-installed conveyor belt 50 has been transferred to the position directly below the pressure head 601 of the pressurizing mechanism 60. When the composite block is transferred directly below the pressure head 601, the infrared sensor feeds back the composite block's position signal to the PC. Based on the received position signal, the PC sends a command to the transmission driver and the pressure driver, causing the transmission driver to control the pre-installed conveyor belt 50 to stop conveying. This allows the pressure driver to control the pressure head 601 to further pressurize and adjust the auxiliary materials pre-installed on the ends of the graphite column to adjust the assembly deviation between the ends of the graphite column and the auxiliary materials.

[0073] Taking the automatic pre-installation of artificial diamond blocks by pre-installation equipment as an example, Figure 1-8 As shown, an automatic pre-assembly method for artificial diamond synthesis blocks provided in an embodiment of the present application includes the following pre-assembly steps:

[0074] S1. Automatic loading of graphite columns. The pre-loading conveyor belt 50 transports the graphite columns to the bottom of the pre-clamping portion 102 of the pre-loading tray 10. The gravity sensor on the pre-loading conveyor belt 50 obtains the gravity signal of the graphite columns and feeds the gravity signal back to the PC end. The PC end sends instructions to the transmission driver, the lifting driver, and the clamping controller, so that the transmission driver controls the stopping of the pre-loading conveyor belt 50, the lifting driver controls the descending of the manipulator 20, and the clamping controller controls the clamping end of the manipulator 20 to clamp the graphite columns.

[0075] S2, auxiliary material pushing and installation, the rotary driver controls the manipulator 20 to rotate in sequence along the steel cup mounting holes 1011, pyrophyllite mounting holes 1012, heating plate mounting holes 1013, stainless steel sheet mounting holes 1014, and plug mounting holes 1015 arranged in the circumferential direction of the disk surface of the pre-loaded disk 10, and auxiliary materials have been prepared manually in advance in each of the auxiliary material mounting holes 101. The pushing mechanisms installed in the steel cup mounting holes 1011, pyrophyllite mounting holes 1012, heating plate mounting holes 1013, stainless steel sheet mounting holes 1014, and plug mounting holes 1015 push and install the auxiliary materials on the graphite column clamped by the manipulator 20 under the control of the pushing driver to form a synthetic block;

[0076] S3: When the composite block is automatically unloaded, the manipulator 20 grips the composite block and rotates to the pre-dropping portion 103 of the pre-loading tray 10. The infrared sensor on the pre-dropping portion 103 obtains a position signal of the manipulator 20 and feeds the position signal back to the PC. The PC sends an instruction to the gripping controller to control the manipulator 20 to drop the composite block onto the pre-loading conveyor belt 50.

[0077] S4. Pressurization and adjustment of the synthetic block. An infrared sensor is provided on the pressure head 601 of the pressurization mechanism 60. When the infrared sensor detects that the synthetic block is transported to the bottom of the pressure head 601 by the pre-installed conveyor belt 50, the infrared sensor feeds back a position signal to the PC. The PC sends an instruction to the pressurization driver to drive the pressure head 601 to pressurize and adjust the synthetic block on the pre-installed conveyor belt 50, so as to adjust the assembly deviation between the two ends of the graphite column and the auxiliary material.

[0078] The method for automatically pre-assembling an artificial diamond synthesis block provided in the embodiments of the present application has at least the following technical effects or advantages:

[0079] Compared with the previous implementation method of pre-assembling artificial diamond synthetic blocks in a purely manual manner, the embodiment of the present application adopts a pre-assembly device mainly composed of a pre-assembly tray 10, a pre-assembly conveyor belt 50, and a pressurizing mechanism 60 to automatically pre-assembly artificial diamond synthetic blocks;

[0080] For example, the graphite column is transported to the bottom of the pre-loading disk 10 by the pre-loading conveyor belt 50, so that the manipulator 20 can descend to clamp the graphite column and complete the automatic loading of the graphite column; the manipulator 20 is controlled by the rotary driver to rotate to the corresponding mounting hole on the disk surface of the pre-loading disk 10, and then the pushing driver controls the pushing mechanism in the mounting hole to push and install the auxiliary material on the graphite column to form a composite block, thereby completing the pushing and installation of the auxiliary material; through the coordination between the manipulator 20 and the pushing mechanism in the mounting hole, the manipulator 20 puts the composite block onto the pre-loading conveyor belt 50, completing the automatic unloading of the composite block; finally, The synthetic block is further pressurized and adjusted by the pressure head 601 of the pressure mechanism 60 above the pre-installation conveyor belt 50 to adjust the assembly deviation between the two ends of the graphite column and the auxiliary material; thereby, the automatic pre-installation of the artificial diamond synthetic block is realized, and there is no need for excessive human intervention throughout the process. The number of personnel on the pre-installation assembly line of the synthetic block has been reduced from the original 10 to 2 people, and only 2 people are needed to replenish the auxiliary material installation holes. This greatly reduces human interference and eliminates the trouble of missing or wrong installation of auxiliary materials in the previous manual pre-installation. Compared with the manual pre-installation of synthetic blocks, it saves two-thirds of the time, thereby improving the pre-installation efficiency and quality.

[0081] Second embodiment

[0082] like Figure 9 As shown, the difference between the embodiment of the present application and the first embodiment is that a push key 41 is used in the steel cup mounting hole 1011 and the talc mounting hole 1012 as a pushing mechanism for pushing the auxiliary material, and the rest of the parts remain unchanged.

[0083] Therefore, a push button 41 is used to replace the L-shaped push rod 40 in the steel cup mounting hole 1011 and the pyrophyllite mounting hole 1012. The push button 41 is designed to be frame-shaped. Driven by a push driver, the push button 41 moves back and forth along the steel cup mounting hole 1011 and the pyrophyllite mounting hole 1012. A clamping claw 411 is movably arranged around the inner wall of the push button 41. The clamping claw 411 can move to extend and retract on the inner wall of the push button 41 to clamp the auxiliary material.

[0084] Therefore, by providing a push button 41 in the steel cup mounting hole 1011 and the pyrophyllite mounting hole 1012 instead of the L-shaped push rod 40, the push driver drives the push button 41 to move within the steel cup mounting hole 1011 and the pyrophyllite mounting hole 1012, thereby fixing the auxiliary material through the gripping 411, thereby driving the auxiliary material and pushing the auxiliary material toward and installing it on the two ends of the graphite column. Because the dimensions of the steel cup, pyrophyllite, and the graphite column are mutually nested and matched, the gripping 411 of the push button 41 can more stably grasp the steel cup and pyrophyllite, accurately installing the steel cup and pyrophyllite on the graphite column. Compared with using the L-shaped push rod 40, the push button 41 has a higher stability in controlling the pushing of the steel cup and pyrophyllite, making it easier to embed the steel cup and pyrophyllite on the graphite column.

[0085] Third embodiment

[0086] like Figure 10 、 11 As shown, the difference between the embodiment of the present application and the first embodiment is that the setting of the pre-installed conveyor belt 50 is different. The pre-installed conveyor belt 50 is replaced by a loading conveyor belt 51 and a unloading conveyor belt 52, and the rest of the parts remain unchanged.

[0087] Specifically, the loading conveyor belt 51 is arranged on the loading side of the pre-loading tray 10 for conveying the graphite columns, and the unloading conveyor belt 52 is arranged on the unloading side of the pre-loading tray 10 for conveying the synthetic blocks formed after the graphite columns and various auxiliary materials are assembled. It can be understood that the pressurizing mechanism 60 is arranged above the unloading conveyor belt 52.

[0088] The advantage of the embodiment of the present application is that the loading conveyor belt 51 and the unloading conveyor belt 52 can control the conveying action independently or synchronously; the height of the unloading conveyor belt 52 on the horizontal plane is greater than the height of the loading conveyor belt 51 on the horizontal plane, so that the unloading conveyor belt 52 can be closer to the pre-delivery part 103 of the pre-loaded tray 10. When the robot 20 puts the synthetic block onto the unloading conveyor belt 52, it can avoid the synthetic block rolling or large deviation in the falling position when it falls onto the unloading conveyor belt 52 due to height problems, thereby affecting the normal processing of the subsequent pressurizing process, thereby ensuring the pre-installation quality of the synthetic block.

[0089] Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if such changes and modifications fall within the scope of the claims and their equivalents, the present invention is intended to include such changes and modifications.
