[0049] In actual use, the materials are manually placed in the feed bin 21, and then the first loading robot 23 picks up the materials in the feed bin 21 and transfers the materials to the positioning mechanism 31 for laser engraving by the laser engraving device 3. At this time, the materials are located on the first side or can be understood as the front side. The material flipping mechanism 32 clamps the materials and flips them over and moves them back to the positioning mechanism 31 for fixation.

After the laser 33 performs laser engraving on the first side and the second side, the first unloading robot 43 picks up the materials after double-sided engraving and transfers them to the receiving bin 41. After the materials in the receiving bin 41 reach a certain level, the materials are taken away manually and sent to the next process, or a robot is set to stack the materials in the receiving bin 41 and transfer them to the next process.

[0050] Specifically, the loading device 2 also includes a fixed frame (not shown) arranged on the machine 1, and a plurality of silo enclosures 24 arranged on the fixed frame.

Afterwards, the laser 33 gradually performs laser engraving on a single material piece, or a plurality of lasers 33 may be provided to improve the engraving efficiency.

[0051] Specifically, the batch laser engraving machine integrating loading and unloading and double-sided laser engraving also includes a material temporary storage mechanism 5, which includes a carrier 51 for storing blister trays, and the carrier 51 is arranged on one side of the laser engraving device 3, and is used in conjunction with the loading device 2, the laser engraving device 3, and the unloading device 4; in this embodiment, the first loading robot 23 has two moving directions, namely the X-axis direction and the Z-axis direction, and the carrier 51 is arranged in the X-axis direction, for receiving the materials transferred by the first loading robot 23 and temporarily storing them, waiting for the second loading robot 26 to pick them up, and the second loading robot 26 also has two moving directions, namely the Y-axis direction and the Z-axis direction; compared with the design in which the first loading robot 23 is directly set to move along the three directions of X, Y, and Z axes, although this design increases the production cost, it improves the rationality of the layout, reduces the failure rate, and thus reduces the maintenance cost and improves the working efficiency.

[0052] Specifically, the machine 1 is provided with a support frame 11, and the first loading robot 23 is arranged on the support frame 11 for reciprocating movement along the X-axis via a group of gear rack modules 25. The first driving member 22 includes a stepper motor 221, and the stepper motor 221 is used to drive the first loading robot 23 to reciprocate along the X-axis. The first driving member 22 also includes a lifting cylinder 222 for driving the first loading robot 23 to reciprocate along the Z-axis direction. Under the action of the stepper motor 221 and the lifting cylinder 222, the first loading robot 23 picks up the materials in the supply bin 21 and transfers them to the material temporary storage mechanism 5.

[0053] Specifically, the first unloading robot 43 and the first loading robot 23 have the same structure, the third driving member 42 and the first driving member 22 have the same structure, the first unloading robot 43 is arranged in parallel with the first loading robot 23, and the first unloading robot 43 is used to pick up the materials processed by the laser 33 in the material temporary storage mechanism 5 and transfer them to the material receiving bin 41.

[0054] In this embodiment, the first loading robot 23 and the first unloading robot 43 are a double lifting mechanism. After all the materials in the material temporary storage mechanism 5 are processed by the laser 33, the first loading robot 23 descends to absorb a tray of materials and rises, and the first unloading robot 43 absorbs the tray in the material temporary storage mechanism 5 and rises. Then the two move horizontally synchronously, and the first loading robot 23 puts the blister tray into the carrier 51 in the material temporary storage mechanism 5, and the first unloading robot 43 transfers the blister tray full of laser-engraved materials to the material receiving bin 41 and then resets it.

[0055] Specifically, the loading device 2 also includes a second loading robot 26 used in conjunction with the first loading robot 23. The second loading robot 26 includes a material picking suction cup 262, a linear module 261 that drives the material picking suction cup 262 to reciprocate along the Y axis, and a fourth driving member 260 that drives the material picking suction cup 262 to reciprocate along the Z axis. Under the action of the linear module 261 and the fourth driving member 260, the material picking suction cup 262 absorbs the material in the blister tray in the material temporary storage mechanism 5 and transfers it to the positioning mechanism 31.

[0056] The second loading robot 26 is provided to cooperate with the first loading robot 23 mentioned above, to make up for its shortcoming of not being able to move along the Y-axis, and to make the overall layout more compact and reasonable, thereby ensuring efficient operation of the equipment while saving ground space.

[0057] Specifically, the unloading device 4 also includes a second unloading robot 44 used in conjunction with the first unloading robot 43. The second unloading robot 44 is arranged on one side of the second loading robot 26. The second unloading robot 44 has the same structure as the second loading robot 26. The second unloading robot 44 is used to pick up the material processed by the laser 33 and transfer it to the blister tray in the material temporary storage mechanism 5. The first unloading robot 43 is used to pick up the material in the blister tray and transfer it to the receiving bin 41. Similarly, the second unloading robot 44 is designed to cooperate with the first unloading robot 43. The second unloading robot 44 can reciprocate along the Y axis and the Z axis, transfer the material processed by the laser engraving device 3 to the material temporary storage mechanism 5, and then pick it up and transfer it to the receiving bin 41 through the first unloading robot 43. On the one hand, it solves the storage of the material after the laser 33 performs batch laser engraving on the material, and on the other hand, it can improve the positional relationship between the devices so that the overall layout is compact and reasonable, saving floor space.

[0058] Specifically, the positioning mechanism 31 includes a loading positioning fixture 311, a laser engraving fixture 312 and a blanking positioning fixture 313. The loading positioning fixture 311 is used to receive the material transferred by the second loading robot 26. The laser engraving device 3 also includes a parallel material taking mechanism 34. The parallel material taking mechanism 34 is used to transfer the material between the loading positioning fixture 311, the laser engraving fixture 312 and the blanking positioning fixture 313. During the operation of the equipment, first, the second loading robot 26 picks up the material to be processed and transfers it to the loading positioning fixture 311, and the loading positioning fixture 311 is used to receive the material transferred by the second loading robot 26. The jig 311 positions the workpiece before laser engraving, and then the parallel material picking mechanism 34 transfers the workpiece in the loading positioning jig 311 to the laser engraving jig 312. After the laser 33 processes the workpiece, the parallel material picking mechanism 34 moves the processed workpiece in the laser engraving jig 312 to the unloading positioning jig 313 for picking up by the second unloading robot 44. Compared with only setting up one positioning jig or manual positioning, this method ensures the accuracy of material processing after multiple positioning processes and reduces the defective rate during material processing.

[0059] Specifically, the parallel material picking mechanism 34 includes a front material picking robot 341 and a back material picking robot 342 arranged in parallel, and a fifth driving member 343 for driving the front material picking robot 341 and the back material picking robot 342 to move back and forth. The front material picking robot 341 and the back material picking robot 342 both have multiple suction nozzles 344 for sucking materials. The front material picking robot 341 is used to suck the materials in the loading positioning fixture 311 and transfer them to the laser engraving fixture 312. The laser 33 is used to laser engrave the materials on the laser engraving fixture 312. The back material picking robot 342 and the front material picking robot 341 are synchronously displaced to suck the materials processed by the laser 33 and transfer them to the unloading positioning fixture 313. The second unloading robot 44 is used to pick up the materials on the unloading positioning fixture 313 and transfer them to the blister tray in the carrier 51.

[0060] In actual use, the front material picking robot 341 absorbs the material in the loading and positioning fixture 311 and transfers it to the front fixture 312a. After the material in the front fixture 312a is processed by the laser 33, the material flipping mechanism 32 picks up the material and flips it over and transfers it to the back fixture 312b; after the laser 33 performs laser engraving on the material in the back fixture 312b, the back material picking robot 342 picks up the material and transfers it to the unloading positioning fixture 313. At this time, the front material picking robot 341 picks up the material in the loading and positioning fixture 311 and transfers it to the front fixture 312a; the synchronous movement of the front material picking robot 341 and the back material picking robot 342 makes the layout of the laser engraving device 3 more compact, and the parallel synchronous displacement of the two makes the movement route shorter, reducing energy loss and error transmission during the movement; in addition, the components of the parallel material picking mechanism 34 are relatively simple and easy to maintain, which reduces the maintenance and replacement costs to a certain extent.

[0061] Specifically, the laser engraving jig 312 includes a front jig 312a and a back jig 312b, the material flipping robot 321 has a "U"-shaped clamp 321a, the second driving member 320 includes a clamping claw cylinder 320a for driving the "U"-shaped clamp 321a to expand and tighten, and a motor 320b for driving the "U"-shaped clamp 321a to rotate, the material flipping robot 321 is used to pick up the material in the front jig 312a and flip it and transfer it to the back jig 312b, and the laser 33 is used to perform laser engraving processing on the material in the front jig 312a and the material in the back jig 312b respectively.

[0062] In this embodiment, two laser engraving jigs 312 are set to realize separate functions respectively, and are used in conjunction with the front material picking manipulator 341 and the back material picking manipulator 342 to realize the function of parallel material picking. The distance between the front material picking manipulator 341 and the back material picking manipulator 342 is equal to the sum of the distances between any three of the above four jigs; when the back material picking manipulator 342 absorbs the material processed by the laser 33 in the back jig 312b and rises, the front material picking manipulator 341 absorbs the material in the loading and positioning jig 311 and rises synchronously, and then the back material picking manipulator 342 transfers the material it absorbs to the unloading and positioning jig 313, and the front material picking manipulator 341 moves synchronously to transfer the material it absorbs to the front jig 312a

[0063] Similarly, when the second unloading manipulator 44 sucks the processed parts in the unloading positioning fixture 313 and transfers them to the temporary storage mechanism 5, the second loading manipulator 26 will pick up the unprocessed parts in the temporary storage mechanism 5 and transfer them to the loading positioning fixture 311 to wait for the next cycle. In this process, the unprocessed parts in the temporary storage mechanism 5 are the front side, and the processed parts are the back side, so there will be no confusion. Compared with manual inspection, this design ensures the yield of laser engraving, avoids repeated laser engraving, and can save floor space and improve the accuracy of laser engraving while ensuring the reasonable overall structural layout, so as to achieve multi-faceted, high-precision, and high-efficiency batch laser engraving.

[0064] The above contents are only preferred embodiments of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there will be changes in the specific implementation methods and application scopes. The contents of this specification should not be understood as limiting the present invention.
