[0018] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0019] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0020] Example 1, as Figures 1 to 4 As shown, this embodiment aims to realize the automatic assembly of diamond synthetic column cores to achieve the purpose of improving work efficiency. Considering that the existing automated assembly line methods are mainly divided into two methods: turntable drive and belt drive, and the diamond synthetic column core needs to be continuously turned over during the assembly process, the turntable drive space is relatively small and needs to be turned over. For this reason, the diamond blank automatic loading device provided in this embodiment includes a frame 1 and a workbench 11 arranged on the top of the frame 1. In this embodiment, the frame 1 is a rectangular frame composed of profiles or steel materials, and the workbench 11 is a layer of steel plate covering the top of the frame 1. A conveyor belt 12 for conveying graphite columns is provided on the workbench 11, and the conveyor belt 12 is an existing common belt conveyor.

[0021] Considering that when synthesizing the diamond synthetic column core, steel cups are first put on both ends of the graphite column, and then white cups are put on both ends. The white cups are wrapped with heating tubes, and the heating tubes are placed in the pyrophyllite half block. The pyrophyllite half block is also inserted at both ends. Finally, graphite sheets and other materials are placed in the hole at the top of the pyrophyllite half block to complete the assembly of the entire diamond synthetic column core. After the conveyor belt 12 has completed the transport of the graphite column, it is necessary to complete the assembly of different components at different positions on the conveyor belt 12. To this end, a first steel cup mounting mechanism 3, a second steel cup mounting mechanism 4, a first white cup mounting mechanism 5, a second white cup mounting mechanism 6, a heating pipe mounting mechanism 7, and a pyrophyllite half-block mounting mechanism 8 are arranged at intervals above the conveyor belt 12 along the direction of movement of the conveyor belt 12. In this embodiment, the first steel cup mounting mechanism 3 is used to install the upper steel cup, the second steel cup mounting mechanism 4 is used to install the lower steel cup, the first white cup mounting mechanism 5 is used to install the lower white cup, the second white cup mounting mechanism 6 is used to install the upper white cup, the heating pipe mounting mechanism 7 is used to install the heating pipe, and the pyrophyllite half-block mounting mechanism 8 is used to install the lower pyrophyllite half-block. In this embodiment, the assembly mechanism for the second pyrophyllite half-block and the graphite sheet is not provided because, after experiments, it was found that mechanical installation was not as fast as manual installation after reaching this point. Therefore, manual labor is used to complete the final assembly. Of course, corresponding arrangements can also be made.

[0022] To facilitate installation of the aforementioned mounting mechanisms, in this embodiment, the frame 1 is further provided with gate-type mounting brackets 13, which are spaced apart along the direction of movement of the conveyor belt 12. Specifically, in this embodiment, rails are provided on both sides of the frame 1, and sliders are provided at the bottom of the gate-type mounting brackets 13. Of course, the gate-type mounting brackets 13 can be locked with bolts, thus facilitating adjustment of the position of the gate-type mounting brackets 13. Thus, the first steel cup mounting mechanism 3, the second steel cup mounting mechanism 4, the first white cup mounting mechanism 5, the second white cup mounting mechanism 6, the heating tube mounting mechanism 7, and the pyrophyllite half-block mounting mechanism 8 are all positioned above the conveyor belt 12 via the gate-type mounting brackets 13.

[0023] Taking into account that the steel cup, white cup, heating tube and pyrophyllite half block are all sequentially placed on the graphite column, which is similar to the situation of nesting dolls, the installation structure can be completely consistent. Therefore, in this embodiment, the first steel cup installation mechanism 3, the second steel cup installation mechanism 4, the first white cup installation mechanism 5, the second white cup installation mechanism 6, the heating tube installation mechanism 7, and the pyrophyllite half block installation mechanism 8 all include a pushing cylinder 21 arranged on the door-type fixing frame 13 and a pushing frame 22 arranged at the power end of the pushing cylinder 21. The purpose of the pushing cylinder 21 is to facilitate the removal of the steel cup, white cup, heating tube or pyrophyllite half block. It pushes the pushing frame 22 in one direction, thereby contacting the steel cup, white cup, heating tube or pyrophyllite half block. After taking the material, press down and install it. In this embodiment, the push rack 22 is arranged in an inverted T-shape. A mounting cylinder 23 is provided at the top of the push rack 22, with the power end of the mounting cylinder 23 facing downward. Since the steel cup, white cup, heating tube, and pyrophyllite half block are of different sizes, and considering that they are installed by downward pressure, the most labor-saving method is to use a negative pressure suction method. To this end, in this embodiment, a suction cup 24 is connected to the power end of the mounting cylinder 23. The suction cup 24 is a negative pressure suction cup, which can effectively grasp the steel cup, white cup, heating tube, or pyrophyllite half block. It should be noted that since the heating tube is tubular, except for the side walls of the heating tube, the other parts are top-sucked, that is, the suction cup 24 of the heating tube is fixed to the finger cylinder.

[0024] In order to facilitate the grabbing of steel cups, white cups, heating tubes or pyrophyllite halves, a material conveyor belt 12 is provided on the side of the suction cup 24 away from the pushing frame 22. In this way, under the action of the pushing cylinder 21, the suction cup 24 moves to the top of the material conveyor belt 12, and the installation cylinder 23 first moves slightly downward to completely grab the steel cup, white cup, heating tube or pyrophyllite halves. Then, the installation cylinder 23 is reset and the pushing cylinder 21 is reset. Then, the suction cup 24 is just above the graphite column. Then, the installation cylinder 23 moves downward to complete the installation.

[0025] Taking into account that the installation process of the entire equipment is progressive, that is, after the upper steel cup is installed, the lower steel cup needs to be installed. At this time, the graphite column is equipped with the upper steel cup, and the upper steel cup is above the graphite column. For this reason, the graphite column needs to be flipped so that the upper steel cup is at the bottom. For this reason, a graphite column flipping mechanism 9 is also provided on the frame 1. The graphite column flipping mechanism 9 includes a flipping cylinder 91 arranged on both sides of the workbench 11 and a flipping frame 92 arranged at the power end of the flipping cylinder 91. In this embodiment, the flipping frame 92 is also arranged in an inverted T-shape. Its main part is to facilitate the installation of the upper finger cylinder 93 and the lower finger cylinder 94 arranged up and down. The purpose of using the finger cylinder is that the finger cylinder can complete the clamping and releasing actions, and the upper finger cylinder 93 and the lower finger cylinder 94 arranged up and down are to avoid the loosening of the installed steel cup, white cup, heating tube or pyrophyllite half block due to flipping, which affects the subsequent actions. The upper and lower clamping method is used to maintain the stability of the relative position.

[0026] In order to better complete the clamping action, in this embodiment, a flip rod 95 is connected between the power ends of the upper finger cylinder 93 and the power ends of the lower finger cylinder 94. In order to ensure the strength of the flip rod 95, the flip rod 95 is a metal rod. Since the finger cylinder has two power ends, a total of four flip rods 95 are set. The two flip rods 95 at the same level move relative to or towards each other under the action of the finger cylinder.

[0027] Relying solely on the clamping of the flip rod 95 may be unstable. For this reason, in this embodiment, a flip suction cup 96 is provided on the flip rod 95, and the flip suction cups 96 on the upper finger cylinder 93 and the lower finger cylinder 94 are relatively arranged. In this way, the size of the finger cylinders can be kept consistent, and only the spacing between the flip suction cups 96 needs to be adjusted.

[0028] To prevent the graphite column from being on the conveyor belt 12, if it is directly turned over, there will be interference problems. Therefore, in this embodiment, the turning cylinder 91 is set up on both sides of the workbench 11. Specifically, a lifting cylinder 14 is set on both sides of the frame 1, and the power end of the lifting cylinder 14 is set upward. The power end of the lifting cylinder 14 is connected to a lifting frame 15. The lifting frame 15 is set in an L shape and is arranged on both sides of the workbench 11. In this way, under the action of the lifting frame 15, the graphite column turning mechanism 9 is first raised, then turned, and then lowered, thereby avoiding interference.

[0029] In order to speed up the work efficiency, a plurality of conveyor belts 12 are arranged at intervals on the workbench 11. In this embodiment, a total of five conveyor belts 12 are arranged according to the clamping strength of the finger cylinder.

[0030] To minimize floor space, in this embodiment, the first steel cup mounting mechanism 3 and the second steel cup mounting mechanism 4 are located on either side of a single door-shaped mounting frame 13. The first white cup mounting mechanism 5 and the second white cup mounting mechanism 6 are located on either side of the same door-shaped mounting frame 13. The heating tube mounting mechanism 7 and the pyrophyllite half-block mounting mechanism 8 are located on either side of the same door-shaped mounting frame 13. In other words, two adjacent mounting mechanisms 2 are located on either side of the same door-shaped mounting frame 13. This not only reduces the overall size of the device but also helps reduce the number of material conveyor belts 12, thereby lowering costs.

[0031] Considering the heavy weight of the pusher frame 22, a guide light shaft 131 is provided on the top of the door-shaped fixing frame 13 to ensure the stability of the pusher frame. The guide light shaft 131 passes through the pusher frame 22, and a linear bearing 221 is provided on the pusher frame 22 to cooperate with the guide light shaft 131. In this way, the support of the guide light shaft 131 ensures the stability of the pusher frame, thereby ensuring the accuracy of the position.

[0032] The above description is merely a preferred embodiment of the present invention and does not constitute any other form of limitation to the present invention. Any person skilled in the art may utilize the technical contents disclosed above to change or modify them into equivalent embodiments with equivalent changes for application in other fields. However, any simple modification, equivalent change, and modification of the above embodiments made in accordance with the technical essence of the present invention without departing from the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
