[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 8 As shown, a pencil sharpener assembly device comprises an assembly table 2, on which a conveying device 21 and a material discharging channel 22 are installed, and a material placing trough 211 capable of placing materials in a limited position is arranged around the conveying device 21; a material placing mechanism, a glue dispensing mechanism, a core pressing mechanism, a material discharge detection mechanism, a material cover pressing mechanism and a material discharging mechanism are sequentially installed on the table top of the assembly table 2 and on one side of the conveying device 21;

[0032] The material placement mechanism includes two symmetrical first sorters 31, two symmetrical first conveying channels 32 matched with the first sorters 31, a first lifting frame 33, a first guide rail 34, and a first material clamping frame 35. The first sorter 31 is connected to the first conveying channel 32. A first material placement table 321 is also installed at one end of the first conveying channel 32 that abuts against the conveying device 21. The first lifting frame 33 is installed with a first guide rail 34. The first guide rail 34 is slidably provided with a first material clamping frame 35. Two first material clamping claws 36 are symmetrically installed at the bottom of the first material clamping frame 35 for clamping the material on the first conveying channel 32 into the material placement slot 211 of the conveying device 21.

[0033] By adopting the above structure, the material is first moved to the conveying channel of the first sorting machine 31 by the centrifugal force of the device in the first sorting machine 31, and then the material is conveyed to the first conveying channel 32 by its conveying channel. After the material is conveyed to the first loading platform 321 of the first loading channel 32, the first lifting frame 33 located on the assembly table 2 can move the vertical position of the first clamping frame 35 by lifting, and then the first clamping frame 35 is moved to the top of the first loading platform 321 through the first guide rail 34, and then the first clamping frame 35 is lowered, so that the two first clamping claws 36 of the first clamping frame 35 can be adjusted down to be able to grasp and clamp the material conveyed to the first loading platform 321, and then the two clamped materials are placed together in the loading slot 211 of the conveying device 21, and the reciprocating operation is performed, so that the loading slot 211 of the conveying device 21 is automatically filled with materials, which is conducive to automatic filling of materials and has high automation efficiency.

[0034] The glue dispensing mechanism includes a second lifting frame 41, a glue storage cylinder 42, a glue dispensing platform 43, a glue dispenser 44 symmetrically arranged on the glue dispensing platform 43, and a retractable material collection basin 45. The second lifting frame 41 is installed on the assembly platform 2, and a glue storage cylinder 42 and a glue dispensing platform 43 are installed on one side of the second lifting frame 41. The glue dispensing platform 43 is installed with a glue dispenser 44. The material collection basin 45 is installed at the bottom of the glue dispensing platform 43 and is located directly below the glue dispenser 44.

[0035] The dispensing platform 43 is provided with a dispensing device 44 that can be lifted upward or downward. Each dispensing device 44 is provided with a lifting member. After the material is filled into the material trough 211, the material connection is automatically dispensed. At the same time, a collecting basin 45 that can move forward or backward according to the dispensing operation is provided. During the dispensing process of the two dispensing devices 44 on the dispensing platform 43, the collecting basin 45 shrinks backward. When the dispensing device 44 finishes dispensing and moves upward, the collecting basin 45 is automatically pushed out to the bottom of the dispensing device 44 in time. The glue remaining and dripping on the glue dispenser 44 can be conveniently collected in the collecting basin 45, which helps to prevent the glue dripping from the glue dispenser 44 from dripping into the material trough 211 of the conveying device 21, and prevents the subsequent materials from being unable to be completely placed in the material trough 211 due to the glue solidifying in the material trough 211. At the same time, it greatly reduces the work of operators who need to clean up the glue due to glue dripping into the material trough 211. The structure is simple, which greatly improves the quality of material assembly, reduces failures and cleaning, and has high automated assembly efficiency.

[0036] The inner core pressing mechanism includes two symmetrical second sorting machines 51, a second conveying channel 52, a third lifting frame 53, a second guide rail 54, a second material clamping frame 55 and a second positioning assembly located on the other side of the conveying device 21. The second sorting machine 51 is connected to the second conveying channel 52. A second material loading table 56 is also installed at one end of the second conveying channel 52 that abuts against the conveying device 21. The second lifting frame 41 is equipped with a second guide rail 54. A second material clamping frame 55 is slidably arranged on the two guide rails. Two second material clamping claws 551 are symmetrically installed at the bottom of the second material clamping frame 55 for clamping the inner core on the second conveying channel 52 into the material loading slot 211 of the conveying device 21.

[0037] After dispensing, the material is transported to the bottom of the second clamping rack 55, and the second sorting machine 51 transports the pencil sharpener inner core to the second material loading platform 56 of the second conveying channel 52 in the same way as the first sorting machine 31. The second lifting frame 41 can also move the vertical position of the second clamping rack 55 by lifting, and then move the second clamping rack 55 to the top of the second material loading platform 56 through the second guide rail 54, and then lower the second clamping rack 55 downward, so that the two second clamping claws 551 of the second clamping rack 55 can be adjusted downward to be able to grasp and clamp the inner core transported to the second material loading platform 56, and then the two clamped inner cores are placed together in the material shell in the material loading slot 211 of the conveying device 21, and the inner core is clamped into the shell of the material. Before clamping and fixing, the first positioning component can align it with the predetermined clamping position to realize accurate automatic placement and clamping operation, which is conducive to accurately placing the inner core into the shell of the material, greatly improving the assembly accuracy, and at the same time, the degree of automation and mechanization is high, which greatly improves the assembly efficiency.

[0038] The material discharging detection mechanism includes a seventh lifting frame 61, on which a first hydraulic cylinder 62 is mounted, and two symmetrical material-checking inserts 63 are fixed below the first hydraulic cylinder 62, and the material-checking inserts 63 are located just above the material-placing slot 211 of the conveying device 21. By providing the material-checking inserts 63, it is convenient to perform real-time detection after the inner core is assembled into the shell of the material, and it is convenient to detect whether the position of the inner core assembly is accurate, further improve the detection accuracy of the material assembly, and also greatly improve the product yield of the material assembly, which is more practical.

[0039] The material cover pressing mechanism includes two symmetrical third sorting machines 71, two symmetrical third conveying channels 72 cooperating with the third sorting machines 71, a fourth lifting frame 73, a third guide rail 74, a first suction frame 75 and a pressing frame 76. The third sorting machine 71 is connected to the third conveying channel 72. A third material placing table 77 is installed at one end of the third conveying channel 72 that abuts against the conveying device 21. The fourth lifting frame 73 is installed with a third guide rail 74. The first suction frame is slidably arranged on the third guide rail 74. 75, two first suction plates 751 are symmetrically installed at the bottom of the first suction rack 75, which are used to suck the material cover on the third conveying channel 72 into the material storage trough 211 of the conveying device 21, and the pressing rack 76 is located on the right side of the third conveying channel 72. The pressing rack 76 has two symmetrical second hydraulic cylinders 761, and each of the second hydraulic cylinders 761 is installed with a first pressing block 762 at the bottom. The shape of the first pressing block 762 is consistent with the shape of the material storage trough 211, which is used to further press down the material cover;

[0040] The discharging mechanism includes a fifth lifting frame 81 of the discharging funnel, a fourth guide rail 82, and a second suction frame 83. The fifth lifting frame 81 is located on the right side of the fourth lifting frame 73. The fifth lifting frame 81 has a fourth guide rail 82. The fourth guide rail 82 has a second suction frame 83. The bottom of the second suction frame 83 has a plurality of second suction plates 831 for sucking the processed materials to the discharge port 221 of the discharging channel 22.

[0041] By arranging a mechanism for pressing the material cover of the material after the dispensing mechanism and the material discharge detection mechanism, the third sorting machine 71 conveys the material cover to the third loading platform 77 of the third conveying channel 72, and then the material cover on the third loading platform 77 is sucked by the first suction plate 751 which can be upgraded and can be moved forward and backward, and then accurately conveyed to the loading trough 211 of the conveying device 21. The material cover can also fit into the loading trough 211 because of its consistent shape and size with the material. Then, the first pressing block 762 on the pressing frame 76 drives the two first pressing blocks 762 through the second hydraulic cylinder 761 to press down and assemble and fix the material and the material cover, which is conducive to automatic assembly and pressing, and greatly improves the assembly efficiency. When discharging, the second suction plate 831 on the second suction frame 83 sucks the assembled and processed material out of the loading trough 211, and then conveys it to the discharge port 221 of the discharge channel 22 for collection and discharge.

[0042] The structure of the present invention is integrated, and the material placement mechanism, the glue dispensing mechanism, the inner core pressing mechanism, the material discharge detection mechanism, the material cover pressing mechanism and the material discharge mechanism are designed in sequence. At the same time, a plurality of detection parts for detecting the material are arranged in each mechanism. The assembly efficiency and the assembly accuracy of the whole device are greatly improved during assembly. The first detector 103 and other detection parts can detect in real time whether the material is operating normally, and an alarm can be issued when a fault occurs. The degree of automation is high and the practicability is stronger. Integrating a plurality of devices into one device greatly reduces the cost of the device and production.

[0043] In the present invention, the first sorting machine 31, the second sorting machine 51 and the third sorting machine 71 are all prior art, and are common equipment for sorting and conveying materials by centrifugal force. The conveying device 21 is a conveyor belt with a plurality of material troughs 211 arranged on the surface.

[0044] In the present invention, the first lifting frame 33, the second lifting frame 41, the third lifting frame 53, the fourth lifting frame 73, the fifth lifting frame 81, and the seventh lifting frame 61 are all frames with lifting components, which can be lifted or lowered.

[0045] Specifically, if Figures 1 to 8 As shown, the first conveying channel 32 is connected to the first loading platform 321, and a first abutment groove 101 is provided on the side of the first loading platform 321 close to the conveying device 21, and two pairs of first clamping grooves 102 are symmetrically arranged on both sides of the first abutment groove 101 according to the matching of the two first clamping claws, and a first detector 103 for detecting whether the material is completely conveyed and abutted is also installed at the bottom of the first abutment groove 101 on the side close to the conveying device 21, and the first detector 103 is connected to the alarm device.

[0046] By adopting the above structure, by setting the first clamping groove 102, the first clamping claw can be moved into the first clamping groove 102, and then the material in the first abutting groove 101 can be clamped. A first detector 103 is also provided at the bottom of the first abutting groove 101, which can detect whether the material is clamped out. If it is not clamped out, an alarm can be issued, which is conducive to real-time detection and prompting operators, and is more practical. At the same time, the material is automatically clamped into the material placing groove 211 of the conveying device 21, which is conducive to automatic assembly.

[0047] like Figures 1 to 8 As shown, the second conveying channel 52 is connected to the second material placement platform 56, and a second abutting groove 104 is provided on the side of the second material placement platform 56 close to the conveying device 21. Two pairs of second clamping grooves 105 are symmetrically provided on both sides of the second abutting groove 104 according to the matching of the two first clamping claws. By providing the second clamping groove 105, the second clamping claw can be moved into the second clamping groove 105, and then the inner core in the second abutting groove 104 can be clamped, which is conducive to automatic assembly and has a better clamping effect.

[0048] like Figures 1 to 8 As shown, the third conveying channel 72 is connected to the third material placement platform 77, and the third material placement platform 77 is provided with a third abutment groove 106 on one side close to the conveying device 21. By providing the third abutment groove 106, the material cover can be conveyed and abutted to the third abutment groove 106 for waiting, and then the first suction plate 751 can accurately suck it and convey it out, so that the automation efficiency is higher.

[0049] like Figures 1 to 8 As shown, there is also a first positioning mechanism between the material placement mechanism and the dispensing mechanism, and the first positioning mechanism is installed on the assembly table 2. The first positioning mechanism includes a second lifting motor 91, a sixth lifting frame 92, a first positioning block 93, and two second pressing blocks 94 symmetrically arranged at the bottom of the first positioning block 93. The shape of the second pressing block 94 is consistent with the shape of the material placement trough 211, and is used to position the pressed material. By setting the second pressing block 94, the previously placed material can be pressed into the material placement trough 211, and the material that is slightly tilted or slightly falls out of the material placement trough 211 can be completely pressed back into the material placement trough 211, which is conducive to playing a good positioning role, and more accurately pressing the material into the material placement trough 211 and pressing it to a precise position, which is conducive to greatly improving the assembly accuracy.

[0050] like Figures 1 to 8 As shown, second detectors 95 are installed on both sides of the first positioning block 93 to detect whether materials are conveyed in the material trough 211. By setting the second detector 95, it is convenient to detect whether materials are placed in the material trough 211 again, and the double detection guarantee greatly improves the assembly quality and detection strength.

[0051] like Figures 1 to 8 As shown, the second positioning assembly includes a mounting plate 1001, a third hydraulic cylinder 1002, and a first pressing plate 1003. The mounting plate 1001 is mounted on the side of the conveying device 21 away from the second conveying channel 52. The bottom of the mounting plate 1001 has a third hydraulic cylinder 1002, and the first pressing plate 1003 is mounted on the third hydraulic cylinder 1002. The first pressing plate 1003 is symmetrically provided with fourth through holes 1004. The fourth through holes 1004 are matched with the shape of the inner core and are provided with placement holes 1005 that are consistent with the shape and size of the inner core. By providing the fourth through hole 1004 and the placement hole 1005 on the first pressing plate 1003, the size of the placement hole 1005 can just fit the inner core of the same size, which is conducive to playing a good limiting positioning role. At the same time, the first pressing plate 1003 is pressed downward, which is conducive to better aligning the second clamping claw 551 to the precise placement and clamping position, greatly improving the assembly accuracy.

[0052] like Figures 1 to 8 As shown, a telescopic rod 46 is installed on the dispensing platform 43, one end of the telescopic rod 46 fixes the dispensing platform 43, and the other end of the telescopic rod 46 is connected to the collecting basin 45 for driving the collecting basin 45 to move forward and backward. By setting a telescopic rod 46, the collecting basin 45 can be moved forward or backward according to the dispensing operation. During the dispensing process of the two glue dispensers 44 on the glue dispensing table 43, the collecting basin 45 shrinks backward. When the glue dispenser 44 finishes dispensing and moves upward, the collecting basin 45 is automatically pushed out to the bottom of the glue dispenser 44 in time. The glue remaining and dripping on the glue dispenser 44 can be conveniently collected in the collecting basin 45, which is beneficial to prevent the glue dripping from the glue dispenser 44 from dripping into the material trough 211 of the conveying device 21, and prevent the subsequent material from being unable to be completely placed in the material trough 211 because the glue solidifies in the material trough 211. At the same time, it greatly reduces the work of operators who need to clean up the glue due to glue dripping into the material trough 211. The structure is simple, the quality of material assembly is greatly improved, and the phenomenon of failure and cleaning is reduced, and the automatic assembly efficiency is high.

[0053] like Figures 1 to 8 As shown, it also includes a control panel 23, which is fixed on the assembly platform 2. By setting the control panel 23, the operator can flexibly adjust parameters according to needs and flexibly set the operation of each driving device, which is more practical.

[0054] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0055] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features.
