DETAILED DESCRIPTION

[0018] In order to more clearly understand the above-mentioned purpose, 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 the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[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 of the following disclosure.

[0020] Embodiment 1, as Figure 1 to Figure 4 As shown, the present embodiment aims to realize the automatic assembly of diamond synthetic column cores to improve work efficiency. Considering that the existing automated assembly lines are mainly divided into two modes: turntable drive and belt drive, and the diamond synthetic column core needs to be constantly turned over during the assembly process, the turntable drive space is relatively small and needs to be turned over. For this reason, the present embodiment provides an automatic loading device for diamond blanks, including a frame 1 and a workbench 11 arranged on the top of the frame 1. In the present embodiment, the frame 1 is a rectangular frame formed by a combination 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 arranged 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, and then the white cups are wrapped with heating tubes, and then the heating tubes are put into the talc half block. The talc half block is also inserted at both ends. Finally, graphite sheets and other materials are put into the hole on the top of the talc half block to complete the assembly of the entire diamond synthetic column core. The conveyor belt 12 completes the conveying of the graphite column, so it is necessary to complete the assembly of different components at different positions of the conveyor belt 12. For this purpose, 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 are arranged at intervals above the conveyor belt 12 along the moving direction of the conveyor belt 12. In this embodiment, the first steel cup installation mechanism 3 is used to install the upper steel cup, the second steel cup installation mechanism 4 is used to install the lower steel cup, the first white cup installation mechanism 5 is used to install the lower white cup, the second white cup installation mechanism 6 is used to install the upper white cup, the heating tube installation mechanism 7 is used to install the heating tube, and the pyrophyllite half-block installation mechanism 8 is used to install the lower pyrophyllite half block. In this embodiment, the assembly mechanism of the second pyrophyllite half block and materials such as graphite sheets is not set because it has been found through experiments that after arriving here, the mechanical installation is not as fast as manual, so the final assembly is completed by manpower. Of course, corresponding settings can also be made.

[0022] In order to facilitate the installation of the above-mentioned installation mechanism, in this embodiment, a door-type fixing frame 13 is also provided on the frame 1, and the door-type fixing frame 13 is arranged at intervals along the moving direction of the conveyor belt 12. Specifically, in this embodiment, rails are arranged on both sides of the frame 1, and a slider is arranged at the bottom of the door-type fixing frame 13. Of course, the door-type fixing frame 13 can be locked by bolts, so that it is convenient to adjust the position of the door-type fixing frame 13. In this way, 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 are all arranged above the conveyor belt 12 through the door-type fixing frame 13.

[0023] Taking into account that the steel cup, the white cup, the heating tube and the talc half-block are all sequentially mounted on the graphite column, which is similar to the situation of nesting dolls, therefore, the installation structures can be completely consistent. Therefore, in this embodiment, 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 talc half-block mounting 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 taking of the steel cup, the white cup, the heating tube or the talc half-block. It pushes the pushing frame 22 in one direction, thereby contacting the steel cup, the white cup, the heating tube or the talc half-block. After taking the material, it can be pressed down for installation. In this embodiment, the push rack 22 is set in an inverted T-shape, and a mounting cylinder 23 is set on the top of the push rack 22. The power end of the mounting cylinder 23 is set downward. Since the steel cup, white cup, heating tube and talc half block are of different sizes, considering that they are installed by downward pressure, the most labor-saving method is to adopt the method of negative pressure adsorption. Therefore, 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 cup, which can effectively grab the steel cup, white cup, heating tube or talc half block. It should be noted that since the heating tube is set in a tubular shape, for this reason, except for the side walls of the heating tube, the others are top adsorption, that is, the suction cup 24 of the heating tube is fixed on the finger cylinder.

[0024] In order to facilitate the grabbing of the steel cup, white cup, heating tube or half piece of pyrophyllite, 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 moves slightly downward first to completely grab the steel cup, white cup, heating tube or half piece of pyrophyllite. 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] Considering 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, and 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 talc 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 the present 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 provided. Two flip rods 95 at the same level move relative to or toward each other under the action of the finger cylinder.

[0027] The clamping by the flip rod 95 alone may be unstable. For this reason, in the present 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] Since the graphite column is prevented from being on the conveyor belt 12, if it is directly turned over, there will be an obstruction problem. Therefore, in this embodiment, the turning cylinder 91 is set 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. A lifting frame 15 is connected to the power end of the lifting cylinder 14. The lifting frame 15 is set in an L shape and is set on both sides of the workbench 11. In this way, under the action of the lifting frame 15, the graphite column turning mechanism 9 first completes the rise, then turns over, and then descends, thereby avoiding interference.

[0029] In order to improve the work efficiency, a plurality of conveyor belts 12 are arranged at intervals on the workbench 11. In this embodiment, according to the clamping strength of the finger cylinder, a total of 5 conveyor belts 12 are arranged.

[0030] In order to reduce the floor space as much as possible, in this embodiment, the first steel cup mounting mechanism 3 and the second steel cup mounting mechanism 4 are respectively on both sides of the same door-type fixing frame 13, the first white cup mounting mechanism 5 and the second white cup mounting mechanism 6 are respectively on both sides of the same door-type fixing frame 13, and the heating tube mounting mechanism 7 and the pyrophyllite half-block mounting mechanism 8 are respectively on both sides of the same door-type fixing frame 13. That is, two adjacent mounting mechanisms 2 are located on both sides of the same door-type fixing frame 13, so that not only the volume of the entire device is reduced, but also the number of material conveyor belts 12 is reduced, thereby reducing costs.

[0031] Considering the heavy weight of the pushing frame 22, in order to ensure the stability of pushing, a guide light shaft 131 is provided on the top of the door-shaped fixing frame 13, and the guide light shaft 131 passes through the pushing frame 22, and a linear bearing 221 matching the guide light shaft 131 is provided on the pushing frame 22. In this way, the stability of pushing is ensured by the support of the guide light shaft 131, thereby ensuring the accuracy of the position.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
