[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 3 In an embodiment of the utility model, a material sheet picking device comprises an X-axis track 1 and a Y-axis track 2, wherein the X-axis track 1 and the Y-axis track 2 are vertically arranged, a frame 3 is fixedly connected to the end of the slide of the Y-axis track 2, a sleeve 6 is detachably installed at the bottom of the frame 3, a bracket 7 is fixedly connected to the top of the sleeve 6, and the bracket 7 is a hollow structure, a suction cup 8 is installed on the top of the bracket 7, a filter mechanism 9 is installed inside and outside the sleeve 6 and at the bottom of the frame 3, and the filter mechanism 9 is used to filter and remove dust entering the inside of the sleeve 6;

[0027] The filter mechanism 9 includes a disassembly assembly, a filter assembly, and a collection box assembly;

[0028] The frame 3 and the sleeve 6 are disassembled and connected via a disassembly assembly;

[0029] The filter assembly is used to filter the dust entering the interior of the sleeve 6;

[0030] The collection box assembly is used to remove and collect dust filtered out by the filter assembly.

[0031] In this embodiment: when the material taking device takes the diode material, the vacuum pump 4 is powered on and operated. The operating vacuum pump 4 makes the connecting pipe 5, the sleeve 6 and the bracket 7 have negative air pressure. Under the action of the internal negative air pressure and the external positive air pressure, the suction cup 8 can suck the diode material, so that the suction cup 8 takes the diode material to the next processing step through the X-axis track 1 and the Y-axis track 2;

[0032] However, when the suction cup 8 sucks the diode sheet, the dust on the surface of the diode sheet will also be sucked into the connecting tube 5, the sleeve 6, and the bracket 7, causing dust to accumulate at the joint between the sleeve 6 and the connecting tube 5. At this time, the filter 905 installed inside the sleeve 6 first filters the vacuum gas mixed with dust, and the filtered dust will adhere to the surface of the filter 905. At this time, the vacuum pump 4 is stopped, and the air pump 904 is powered on to operate, so that the running air pump 904 provides suction to the rubber hose 9011. Because the open end of the rubber hose 9011 is located below the filter 905, the gas output from the rubber hose 9011 sucks the dust attached to the surface of the filter 905 into the collection box 903. The collecting box 903 collects the dust filtered out by the filter screen 905 (it should be noted that: a valve is provided at the open end of the jack 9010, and when the vacuum pump 4 is in operation, the controller controls the valve to be in a closed state, and the air pump 904 is in a stopped state, then the inside of the sleeve 6 is in a sealed state, and when the vacuum pump 4 is in a stopped state, the controller controls the valve to be in an open state, and the air pump 904 is in operation, then the inside of the sleeve 6 is connected to the collecting box 903), and the bent portion of the second connecting rod 907 and the first connecting rod 906 are completely accommodated in the "L"-shaped accommodating groove 9012, and the bent portion of the second connecting rod 907 is flush with the top of the sleeve 6;

[0033] After the collection box 903 has collected dust for a period of time, the dust inside it needs to be cleaned. At this time, the threaded head 901 is unscrewed from the sleeve 6, and the separated threaded head 901 and the internal thread 902 disassemble the sleeve 6 and the frame 3, and then the first connecting rod 906 is pulled out from the inside of the "L"-shaped receiving groove 9012, and the "T"-shaped slider 909 is pulled out from the inside of the "T"-shaped slide groove 908, so that the filter screen 905 and the collection box 903 can be removed from the sleeve 6 at the same time, thereby facilitating the cleaning of the filter screen 905 and the collection box 903.

[0034] Please refer to Figure 1 A vacuum pump 4 for providing suction to the suction cup 8 is installed on the top of the frame 3, and a connecting pipe 5 is fixedly connected to the butt end of the vacuum pump 4.

[0035] In this embodiment, the vacuum pump 4 is powered on and operated, so that the connecting tube 5, the sleeve 6 and the bracket 7 are in negative pressure. The suction cup 8 can hold the diode sheet under the action of the internal negative pressure and the external positive pressure.

[0036] Please refer to Figure 2 , the disassembly assembly includes a thread head 901 and an internal thread 902;

[0037] The thread head 901 is installed at the bottom end of the frame 3 , and a through hole is provided inside the thread head 901 for the connecting pipe 5 to pass through. The internal thread 902 is arranged on the inner wall of the sleeve 6 , and the internal thread 902 is threadedly connected to the thread head 901 .

[0039] Please refer to Figure 3 The filter assembly includes a filter 905, a first connecting rod 906, a second connecting rod 907, a "T"-shaped slide groove 908, a "T"-shaped slider 909 and an "L"-shaped receiving groove 9012;

[0040] The filter screen 905 is fixedly connected to the bottom end of the first connecting rod 906, and the filter screen 905 is disassembled and installed inside the sleeve 6. One end of the second connecting rod 907 is fixedly connected to the top of the first connecting rod 906. The "L"-shaped receiving groove 9012 is opened on the inner wall of the sleeve 6, and the "L"-shaped receiving groove 9012 is used for the first connecting rod 906 to be inserted into it. The "T"-shaped slide groove 908 is opened on the outer wall of the sleeve 6. The "T"-shaped slider 909 is slidably connected to the inside of the "T"-shaped slide groove 908, and the "T"-shaped slider 909 is fixedly connected to the second connecting rod 907.

[0044] In this embodiment: the vacuum pump 4 is stopped, and the air pump 904 is powered on to provide suction to the rubber hose 9011. Since the open end of the rubber hose 9011 is located below the filter 905, the gas output from the rubber hose 9011 sucks the dust attached to the surface of the filter 905 into the collection box 903, and the collection box 903 collects the dust filtered out by the filter 905.

[0045] Please refer to Figure 3 The other end surface of the collecting box 903 is in contact with the outer wall of the sleeve 6 , and the open end of the rubber hose 9011 is located below the filter screen 905 .

[0046] In this embodiment, because the open end of the rubber hose 9011 is located below the filter 905 , the gas output from the rubber hose 9011 can suck the dust attached to the surface of the filter 905 into the collection box 903 .

[0047] Please refer to Figure 3 A sealing member 10 is disposed on the end surface of the first connecting rod 906 , and the sealing member 10 is used to improve the sealing performance of the threaded connection between the threaded head 901 and the internal thread 902 .
