SUMMARY

[0004] The present application provides an automatic assembly and packaging machine for pens, which is suitable for products with huge market demand, multiple assembly processes and long-term assembly.

[0005] The technical scheme of the present application is as follows: an automatic assembly and packaging machine for pens, wherein the pen cap, the pen body and the pen sleeve are separately arranged by a tray. The finished pen after assembly is packaged by a packaging box. The machine further comprises a rack a, a feeding module, an assembly module, a packaging module and a carrying module,

[0006] The feeding module is used for conveying the separately arranged trays of the pen cap, the pen body and the pen sleeve. The feeding module has a feeding channel A for supporting the trays and realizing transportation. When feeding, the trays stop transportation. At this time, the carrying module can carry the pen cap, the pen body and the pen sleeve separately arranged by the trays to the assembly module to realize feeding.

[0007] The assembly module is used for assembling the pen cap, the pen body and the pen sleeve into a finished pen. The assembly module has an assembly rack, and pen cap clamps, pen body clamps and pen sleeve clamps distributed on the assembly rack in an upper-middle-lower manner. The pen cap clamps can drive the clamped pen cap downward. The U disk plug on the pen cap is also pre-inserted into the interface on the tail end of the pen body to form a pen cap and pen body pre-insertion. After the pen body clamps release the pen cap and pen body pre-insertion, the pen head of the pen body freely falls into the pen sleeve clamped by the pen sleeve clamp and is supported by the pen sleeve. Then, the pen cap is pressed downward by the upper pressing block so that the pen cap and the pen sleeve are tightly pressed on the two ends of the pen body. The finished pen after assembly is clamped by the pen sleeve clamp.

[0008] The packaging module supports the box body of the packaging box and realizes the conveying track B for transportation.

[0056] When the body clamp 23 is in the first position, the correction block 26 can be inserted into the interface on the tail end of the body clamped by the body clamp 23 below to correct the body.

[0057] When the body clamp 23 is in the second position, the cap clamp 22 drives the cap downward and the U disk plug on the cap can be pre-inserted into the interface on the tail end of the body clamped by the body clamp 23 to perform cap and body pre-insertion operation.

[0058] When the body clamp 23 is in the third position, the pressing block 25 presses the cap to make the cap and the sleeve tightly pressed on the two ends of the body, realizing the assembly of the cap, the body and the sleeve.

[0059] Specifically, the cap clamp 22 on the upper layer can be vertically lifted, the barrel clamp 23 on the middle layer can be horizontally reciprocated, and the sleeve clamp 24 on the lower layer can be horizontally slid and vertically lifted.

[0060] The packaging module 3 has a box body supporting the packaging box and a conveying track B31 (the conveying track B31 is a transmission chain or a transmission belt) for conveying, the box body of the packaging box stops conveying during the packaging operation, at this time, the finished pen clamped by the sleeve clamp 24 can be conveyed and loaded into the box body by the conveying module, and the cover of the packaging box can also be conveyed and covered on the box body, so as to realize the packaging of the finished pen; specifically, the packaging module 3 further comprises a box clamping tool 32 for clamping the box body of the packaging box and can lift the box body upward or place the box body on the conveying track B31; specifically, the packaging module 3 further comprises a code printing machine 33 for printing codes on the packaging box;

[0061] Specifically, the rack a further comprises a storage bin a1, the storage bin a1 has multiple storage layers 6, and multiple trays can be placed on one storage layer 6, and the storage layer 6 has multiple tray placing areas 61 in the horizontal direction, and the conveying track A11 upstream communicates with the storage bin a1, and the conveying module can convey the trays on the storage layer 6 to the conveying track A11 upstream. The rack a further comprises a discharge port a2 on the front side, which communicates with the conveying track B31 downstream and can discharge the packaged finished pen.

[0062] Specifically, the conveying module comprises a conveying manipulator one 41, a conveying manipulator two 42 and a gantry conveying structure 43,

[0063] The conveying manipulator one 41 clamps and sends the cap, the barrel and the sleeve on the conveying track A11 which stops conveying to the corresponding clamp to realize feeding, and further comprises multiple clamping heads for adapting to the structure of the cap, the barrel and the sleeve;

[0064] The conveying manipulator two 42 clamps and conveys the box body to the conveying track B31, clamps and loads the finished pen clamped by the sleeve clamp 24 into the box body which stops conveying, and conveys and covers the cover on the box body; of course, one conveying manipulator can be provided to complete the clamping operation required during feeding and packaging.

An automatic assembly and packaging machine for pens according to claim 1, 2, or 3, characterized in that: It also includes a correction block (26), which matches the interface on the end of the pen body. The correction surfaces (26a) on both sides of the bottom insertion position of the correction block (26) are inclined. Before the pen cap and pen body are pre-inserted, the correction block (26) can be inserted downward into the interface on the end of the pen body to correct the position of the pen body held on the pen body clamp.

8. An automatic assembly and packaging machine for pens according to claim 7, characterized in that: The pressing block (25) can be driven up and down by a lifting machine. The bottom end face of the pressing block (25) is the pressing surface (25a) that presses against the pen cap. The correction block (26) is telescopically mounted on the pressing block (25) and can extend downwards out of the pressing surface (25a) or retract upwards.

9. An automatic assembly and packaging machine for pens according to claim 7, characterized in that: The pen cap clamp (22) and the pen sleeve clamp (24) are also staggered vertically. The pen body clamp (23) can reciprocate and has the following positions: a first position corresponding to the position directly below the correction block (26), a second position corresponding to the position directly below the pen cap clamp (22), and a third position that is in the same vertical direction as the clamping block (25) and the pen sleeve clamp (24). When the pen body clamp (23) is in the first position, the correction block (26) can be inserted downward into the interface on the end of the pen body held by the lower pen body clamp (23) to perform pen body correction; When the pen body clamp (23) is in the second position, the pen cap clamp (22) drives the pen cap downward and allows the USB plug on it to be pre-inserted into the interface on the end of the pen body held by the pen body clamp (23), thus performing the pre-insertion operation of the pen cap and the pen body. When the pen body clamp (23) is in the third position, the pressing block (25) presses down on the pen cap so that the pen cap and pen sleeve are pressed tightly on both ends of the pen body, thereby realizing the assembly of the pen cap, pen body and pen sleeve.

10. An automatic assembly and packaging machine for pens according to claim 1, 2, or 3, characterized in that: The pen cap clamp (22) is also equipped with a pre-pressing rod (27). After the pen cap clamp (22) releases the pen cap, the pre-pressing rod (27) can fall freely due to its own weight, pressing the USB plug on the pen cap downward into the interface on the end of the pen body.
