Description

Technical Field

[0001] The utility model relates to the technical field of weight classification of disc products, in particular to a graphite disc separation device. Background Art

[0002] Graphite discs are key components in the synthetic diamond synthesis technology industry. They are made of graphite sheets through stamping equipment. They have a relatively smooth surface and are ultra-thin, making it difficult to achieve automated weight separation. In the production and use process, they are generally manually weighted or not weighted. The main problems are as follows: 1. When weight separation is not performed, the synthesis current will be unstable during diamond synthesis, and diamonds may easily aggregate or not grow, and the quality of diamond crystals is poor. In addition, the weight change of graphite sheets causes current fluctuations to produce blasting, resulting in the consumption of carbide top hammers; 2. When manual weight separation is used, the efficiency is low and the cost is high. In addition, the error rate of manual weight separation is high, and it is difficult to ensure the weight separation quality. In addition, manual weight separation will cause the human body to inhale excessive graphite dust, affecting the health of the staff. For this reason, our company has proposed an automated weight separation system for graphite discs. The separation device of graphite discs is a pre-process of the automated weight separation system. The graphite discs are first transported to the assembly line piece by piece, which can greatly facilitate the subsequent weight separation work. Summary of the invention

[0017] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent.

For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted. DETAILED DESCRIPTION

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Embodiment 1

[0020] like Figure 1 and Figure 2As shown, a graphite wafer separation device of the present embodiment includes a fixed plate 312, on which a second material barrel 313 for loading graphite wafers and a material guide trough 310 for successively guiding the graphite wafers out are provided, above the second material barrel 313 is provided a suction cup 301 for taking out the graphite wafers inside one by one, the suction cup 301 is arranged at the end of a buffer hardware 302, the buffer hardware 302 is connected to a first cylinder 304 for controlling its forward and backward movement, the first cylinder 304 is connected to a second cylinder 303 for controlling its upward and downward movement, and the second cylinder 303 is arranged on the fixed plate 312. The second cylinder 303 drives the first cylinder 304, the buffer hardware 302 and the suction cup 301 to move up and down, and the first cylinder 304 drives the buffer hardware 302 and the suction cup 301 to move forward and backward. When moving downward, the suction cup 301 penetrates into the second barrel 313 to absorb a graphite disc. After moving forward to the top of the guide groove 310, the first suction cup 301 is released, and the graphite disc absorbed by it enters the next process along the guide groove 310.

[0021] The suction cup 301 of this embodiment is fixed on the buffer hardware 302, which has a piston and a spring inside, and the suction cup 301 is connected to one side of the piston. As the material in the second barrel 313 increases or decreases, the downward and upward distances of the suction cup are dynamically adjusted by the compression amount of the spring. When the cylinder does not apply pressure, the piston will be pushed toward the suction cup by the spring, so that the suction cup remains tightly attached to the surface of the object. When the cylinder applies pressure, a difference in air pressure will occur. The other side of the cylinder usually establishes an air pressure higher than the ambient air pressure through an air pressure source. This forms a negative pressure area (also called a vacuum area) on one side of the cylinder, while a positive pressure area is formed on the side where the suction cup is tightly attached to the surface of the object. The suction force in the negative pressure area will cause the suction cup to generate an adsorption force with the surface of the object, so that it adheres tightly. This adsorption force enables the suction cup to fix and maintain the position of the object. When the object needs to be released, the adsorption force between the suction cup and the object can be reduced by changing the state of the air pressure. Usually, the cylinder connects the side where the suction cup is connected to the ambient air pressure, thereby eliminating the negative pressure area. In this way, the adsorption force between the suction cup and the object is reduced, so that the suction cup can be easily separated from the object. In general, the suction cup fixing cylinder fixes and releases the object by utilizing the air pressure difference and the negative pressure effect. This structure is an existing conventional technology and will not be described in detail in this embodiment.

[0022] In some embodiments, the first cylinder 304 may be configured to move up and down, and the second cylinder 303 may be configured to move left and right, so as to achieve the up and down, front and back movements of the suction cup 301 and the buffer fitting 302 .

[0023] In order to enable the device to work continuously and not be interrupted due to lack of material in the second material barrel 313 (when the suction cup 301 takes material from the second material barrel 313, it is impossible to refill the second material barrel 313), a first material barrel 309 with the same specifications as the second material barrel 313 is also provided, a turntable 308 and a motor 307 for driving the turntable 308 to rotate are provided on the fixed plate 312, and the first material barrel 309 and the second material barrel 313 are symmetrically arranged relative to the central axis of the turntable 308. In this way, when the suction cup 301 takes material from the second material barrel 313, the first material barrel 309 can be refilled, and when the second material barrel 313 lacks material, the turntable 308 is rotated to interchange the positions of the two material barrels, so that the separation work can be carried out continuously.

[0024] Of course, in some embodiments, the motor 307 may not be provided, and the turntable 308 may be rotated manually.

[0025] The fixed plate 312 is provided with a first proximity switch 305 for detecting the number of graphite discs in the first barrel 309 and / or the second barrel 313. When there is too much material in the first barrel 309 and too little or exhausted material in the second barrel 313, the first proximity switch 305 will promptly send out an alarm signal to indicate the risk. In the actual weight division process, the speed of the graphite sheets added to the first barrel 309 is much faster than the speed of the graphite sheets taken from the second barrel 313. Therefore, it is also possible to monitor only the material situation in the first barrel 309. When the material is full, the turntable 308 is rotated, and the material in the second barrel 313 is not exhausted at this time; after the turntable 308 is rotated, the material situation in the second barrel 313 is monitored, and when the second barrel 313 is full, the material in the first barrel 309 is not exhausted.

[0026] In order to ensure that the turntable 308 is in place each time it rotates and the positions of the two barrels are interchanged, a second proximity switch 306 for detecting the position of the first barrel 309 and / or the second barrel 313 is provided on the fixed plate 312 to ensure that the rotation angle of the motor 307 is reliable.

[0027] In order to make the slope of the guide trough 310 adjustable, a support frame 311 is provided on the fixed plate 312, and the guide trough 310 and the support frame 311 are respectively provided with a first long hole 321 and a second long hole 322 that cooperate with each other. Different slopes are adjusted according to different sizes and smoothness of graphite discs to avoid the situation where the slope is too small and the graphite discs cannot flow out stably, and at the same time to avoid the situation where the slope is too large, resulting in excessive speed of the graphite discs, which damages the disc products or the next process equipment.
