[0034] Example

[0035] In order to solve the existing technology of laser engraving, information code detection, appearance inspection and handling and packaging of the shaft, the company needs to invest a lot of labor costs, the overall work efficiency is relatively low, and it is impossible to ensure that the shaft placed in the crisp disk K is not short-loaded. Figure 1 and Figure 2As shown, the present application discloses an automated packaging equipment for preventing short-packaging, including a laser engraving detection line 20 for conveying a turntable 10 to move and performing laser engraving, code scanning detection and appearance inspection on the output in the turntable, a defective product recovery box 30 arranged below the laser engraving detection line 20 for recovering defective products, a longitudinal drive assembly 40 arranged next to the laser engraving detection line 20, a truss 50 connected to the longitudinal drive assembly 40, a transverse drive assembly 60 arranged on one side of the crossbeam of the truss 50, a crisp plate K placement platform 70 arranged in the middle of the longitudinal drive assembly 40 for placing the crisp plate K, a lifting weighing platform 80 arranged in the middle of the longitudinal drive assembly 40 for weighing the crisp plate K, a lifting manipulator 90 connected to the transverse drive assembly 60 for grabbing the qualified products in the turntable 10 into the crisp plate K, and a lifting push plate 100 arranged on the other side of the crossbeam of the truss 50 for pushing the crisp plate K.

[0036] During the specific implementation process, the operator first places an empty crisp disk K on the crisp disk K platform, and then places the middle turntable 10 equipped with the rotating shaft onto the laser engraving inspection line 20 for laser engraving, code scanning inspection and appearance inspection. In the process of the longitudinal drive component 40 driving the truss 50 to move longitudinally and the transverse drive component 60 driving the lifting manipulator 90 to move transversely, the lifting manipulator 90 transports the rotating shafts that have passed the inspection in the middle turntable 10 to the crisp disk K, and places the unqualified rotating shafts into the unqualified product recycling box 30. When the crisp disk K is full of rotating shafts, the longitudinal drive component 40 drives the truss 50 to move longitudinally, and the lifting push plate 100 pushes the crisp disk K to the lifting weighing platform 80 for weighing. According to the weighing result, it can be determined whether there is a short-installed rotating shaft in the crisp disk K.

[0037] refer to Figure 3 As shown, the surface of the central turntable 10 of the present application is provided with a plurality of slots 11 for placing the rotating shafts at equal intervals, and the side of the central turntable 10 is provided with a plurality of through holes 12 corresponding to the slots 11 at equal intervals.

[0038] refer to Figure 3 As shown, the laser engraving inspection line 20 of the present application includes a belt conveyor 21, a laser engraving machine head 22, a code scanner 23, a CCD visual inspection camera 24 and a turntable 10 recovery box. A first bracket 26 is provided on the outer side of the belt conveyor 21 near its conveying starting end, a second bracket 27 is provided on the outer side of the belt conveyor 21 behind the first bracket 26, and a third bracket 28 is provided on the outer side of the belt conveyor 21 near its conveying end. The laser engraving machine head 22 is fixed to the top of the belt conveyor 21 through the first bracket 26, the code scanner 23 is fixed to the top of the belt conveyor 21 through the second bracket 27, the CCD visual inspection camera 24 is fixed to the top of the belt conveyor 21 through the third bracket 28, and the turntable recovery basket 25 is obliquely arranged on the outside of the conveying end of the belt conveyor 21;

[0039] When the rotating shaft in the middle turntable 10 reaches below the laser engraving head 22, the laser engraving head 22 will laser engrave the information code on the rotating shaft;

[0040] When the rotating shaft in the middle turntable 10 reaches below the code scanner 23, the code scanner 23 will scan and detect the information code engraved on the rotating shaft;

[0041] When the rotating shaft in the middle turntable 10 reaches below the CCD visual inspection camera 24, the CCD visual inspection camera 24 performs an appearance inspection on the rotating shaft. It should be noted here that the CCD visual inspection camera 24 of the present application needs to take pictures continuously.

[0042] Also refer to Figure 4 As shown, the belt conveyor 21 of the present application is provided with two first positioning blocks 29 corresponding to the first bracket 26 on both sides of the conveying starting end, the belt conveyor 21 is provided with two second positioning blocks 211 corresponding to the second bracket 27 on the rear sides of the two first positioning blocks 29, and the belt conveyor 21 is provided with two third positioning blocks 212 on both sides of the conveying end. The present application can position and convey the turntable 10 through the two first positioning blocks 29, the two second positioning blocks 211 and the two third positioning blocks 212, thereby ensuring the accuracy of information code laser engraving, information code scanning detection and appearance detection.

[0043] Also refer to Figure 4 As shown, one of the first positioning blocks 29 of the present application is provided with a first clamping cylinder 213, a group of corresponding sensors a are provided on the two second positioning blocks 211, and a group of corresponding sensors b are provided on the two third positioning blocks 212. One of the third positioning blocks 212 is provided with a second clamping cylinder 216 on the front side of the group of corresponding sensors b, and a clamping plate 217 is connected to the piston rod of the second clamping cylinder 216.

[0044] When the belt conveyor 21 drives the turntable 10 to move, the first clamping cylinder 213 will drive its piston rod to reciprocate and extend (as for how to ensure that the piston rod can be inserted into the through hole 12 every time, it is necessary for those skilled in the art to control the running speed of the belt conveyor 21 and the extension and retraction interval of the piston rod of the first clamping cylinder 213 during specific implementation). When the piston rod of the first clamping cylinder 213 is inserted into each through hole 12 of the turntable 10, the turntable 10 will stay under the laser engraving head 22. In this way, the laser engraving head 22 can laser engrave the information code on the rotating shaft in the corresponding slot 11;

[0045] When the light emitted by the light emitter of a set of photoelectric sensors a214 (known technology) passes through each through hole 12 of the turntable 10 and is received by the light receiver, it means that a slot 11 has reached the corresponding position. At this time, the code scanning and detection mechanism will scan and detect the information code on the rotating shaft of the slot 11;

[0046] When the light emitted by the light emitter of a group of reflected photoelectric sensors b215 (known technology) passes through the first through hole 12 of the turntable 10 and is received by the light receiver, the second clamping cylinder 216 will drive the clamping plate 217 to extend and clamp the turntable 10 until the rotating shafts in all the slots 11 are removed and then reset.

[0047] When all the rotating shafts in the intermediate turntable 10 are placed in the crisp disk K by the lifting robot 90 , the intermediate turntable 10 will be moved to the intermediate turntable recovery basket 25 for recovery.

[0048] refer to Figure 1 and Figure 2 As shown, the longitudinal drive assembly 40 of the present application includes a first servo linear module 41 and a linear guide 42 arranged side by side. The two legs of the truss 50 are respectively connected to the first servo linear module 41 and the linear guide 42. Under the drive of the first servo linear module 41, the truss 50 can move longitudinally on the first servo linear module 41 and the linear guide 42.

[0049] As a preferred embodiment, the transverse drive assembly 60 of the present application is a second servo linear module, and under the drive of the second servo linear module, the lifting robot 90 can move laterally.

[0050] refer to Figure 1 and Figure 2 As shown, the crisp plate K placement platform 70 of the present application includes two longitudinal support plates 71 arranged side by side and a step plate 711 relatively arranged above the inner side of the longitudinal support plate 71. During the specific implementation, the operator places the crisp plate K on the two step plates 711 and under the push of the lifting push plate 100, the crisp plate K can move longitudinally on the two step plates 711.

[0051] refer to Figure 5 As shown, the lifting and weighing platform 80 of the present application includes a first lifting drive cylinder 81 arranged between two longitudinal support plates 71, a lifting platform 82 connected to the piston rod of the first lifting drive cylinder 81, and a weighing sensor 83 arranged on the lifting platform 82. When the crisp disk K is full of rotating shafts, the first lifting drive cylinder 81 will drive the lifting platform 82 to rise so that the crisp disk K is located above it. In this way, the weighing sensor 83 will detect the overall weight of the crisp disk K. If the weight weighed by the weighing sensor 83 is within the set value, it means that the rotating shaft in the crisp disk K is not short-loaded. On the contrary, if the weight weighed by the weighing sensor 83 is less than the set value, it means that the rotating shaft in the crisp disk K is short-loaded.

[0052] refer to Figure 6As shown, the lifting manipulator 90 of the present application includes a movable slide connected to the transverse drive assembly 60, a first pneumatic slide 91 provided on the movable slide, an L-shaped plate 92 provided on the first pneumatic slide 91, and an electromagnet 93 provided at the bottom of the L-shaped plate 92. In the process of transporting the qualified rotating shaft in the turntable 10 to the crisp plate K, the longitudinal drive assembly 40 moves the truss 50 longitudinally, and the transverse drive assembly 60 moves the first pneumatic slide 91 longitudinally. When the electromagnet 93 is located above a slot 11 of the turntable 10, the first pneumatic slide 91 will drive the L-shaped plate 92 downward. The electromagnet 93 is lowered and energized, and the shaft can be adsorbed when the electromagnet 93 contacts the shaft. After that, the first pneumatic slide 91 drives the L-shaped plate 92 to reset. The longitudinal drive component 40 again moves the truss 50 longitudinally, and the transverse drive component 60 again moves the first pneumatic slide 91 longitudinally. When the electromagnet 93 is located above the empty slot of the crisp disk K, the first pneumatic slide 91 will again drive the L-shaped plate 92 to lower and deenergize the electromagnet 93. In this way, the shaft will be placed in the empty slot of the crisp disk K. After that, the first pneumatic slide 91 again drives the L-shaped plate 92 to reset.

[0053] According to the above operation process, the lifting robot 90 can continuously transport the qualified rotating shafts in the intermediate turntable 10 and place them in the crisp tray K.

[0054] refer to Figure 7 As shown, the lifting push plate 100 of the present application includes a second pneumatic slide 101 provided on the crossbeam of the truss 50 and a T-shaped push plate 102 provided on the second pneumatic slide 101. When the longitudinal drive component 40 drives the truss 50 to move and makes the second pneumatic slide 101 and the T-shaped push plate 102 located at the front side of the crisp disk K, the second pneumatic slide 101 drives the T-shaped push plate 102 to descend and contact the crisp disk K. When the longitudinal drive component 40 drives the truss 50 to move longitudinally, the crisp disk K can move longitudinally on the two step plates 711 to directly above the lifting weighing platform 80.

[0055] refer to Figure 8 As shown, the present application provides a blocking mechanism 110 in the middle of the two longitudinal support plates 71, and the blocking mechanism 110 includes a second lifting drive cylinder 111, and the second lifting drive cylinder 111 is connected to a lifting baffle 112 for positioning the crisp disk K. When the crisp disk K is initially positioned, the second lifting drive cylinder 111 first drives the lifting baffle 112 to rise, and the longitudinal drive component 40 then drives the truss 50 to move and make the second pneumatic slide 101 and the T-shaped push plate 102 located at the front side of the crisp disk K. When the second pneumatic slide 101 drives the T-shaped push plate 102 to descend and contact the crisp disk K, the longitudinal drive component 40 drives the truss 50 to move longitudinally so that the crisp disk K is blocked by the lifting baffle 112.
