Description

Technical Field

[0001] The invention relates to the technical field of loading and unloading manipulators, and in particular to an automatic loading and unloading manipulator device for a laser marking machine. Background Art

[0002] Laser marking machines use laser beams to mark permanent marks on the surfaces of various materials. The effect of marking is to expose the deeper materials through the evaporation of the surface materials, thereby engraving exquisite patterns, trademarks and texts. Most laser marking machines are equipped with a transmission mechanism and two sets of loading and unloading manipulators. One set of manipulators places the product to be processed on the transmission mechanism for transfer, and then the main part of the laser marking machine completes the product marking and then removes it through another set of manipulators.

[0003] Most of the existing manipulators for laser marking machines are composed of a translation truss, a support frame, a telescopic cylinder, a base and a suction cup assembly. The vertical and horizontal positions of the suction cup assembly are adjusted to make it located above the product. The suction cup assembly moves downward to contact the top of the product and adsorbs the product. After the suction cup drives the product to move upward and horizontally in turn, the product position is transferred.

[0004] During the operation of the above-mentioned laser marking machine robot, its main working part is the adsorption of the suction cup assembly on the top of the product, and the premise of adsorption is that there must be sufficient contact surface between the bottom of the suction cup assembly and the top of the product, that is, the bottom of the suction cup assembly must completely contact the product, but the tops of some existing products are not regular planes. For the sake of aesthetics or usage requirements, a slope is set on the top of the product. In this case, when the suction cup assembly contacts the top of the product, part of the bottom of the suction cup assembly is prone to be suspended, resulting in the suction cup assembly being unable to successfully complete the adsorption of the product, thereby reducing the scope of application of the automatic loading and unloading robot equipment of the laser marking machine. Summary of the invention

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0017] 1. In the present application, when the outer frame remains in a straight state, the telescopic cylinder pushes the base to move downward, and the base drives the suction cup assembly to move downward through the bottom rod, and the suction cup assembly can be directly adsorbed on the top of the product. When there is an inclined surface on the top of the product, the swing frame is manually moved first to make its open end separate from the outer wall of the driving rod, and then the turntable is driven to rotate by the driving rod. During the rotation of the turntable, the outer sleeve movably installed on the outer wall will change its position, and the outer sleeve slides along the outer wall of the light rod to provide an axial driving force for the light rod, and the light rod drives the rotating sleeve and the bent rod to deflect axially.

At this time, the multiple groups of connecting rods and the suction cup assemblies at their bottom are tilted as a whole, but because the connecting rods and the suction cup assemblies are rotationally matched, the multiple groups of suction cup assemblies at this time remain straight. Then the telescopic cylinder drives the base downward, and one end of each suction cup assembly contacts different positions of the inclined surface of the product at the same time. Then, as the bottom rod continues to descend, the suction cup assembly is gradually attracted to the inclined surface, so that the overall suction cup assembly can be tilted according to the use requirements, so as to adapt to the transfer requirements of different products, thereby improving the application range of the automatic loading and unloading robot equipment of the laser marking machine.

[0018] The cam is in a state of tension, and the reaction force of the spring is used to stabilize the position of the multiple bottom rods. The servo motor can be controlled to drive the screw to rotate, and the outer wall of the screw is screwed with the inner wall of the moving frame. At the same time, the moving frame is axially limited by the slot, so that the moving frame will drive the pushing sleeve to move, and the inner wall of the pushing sleeve slides with the outer wall of the sliding sleeve, while driving the pulling rope part of the outer wall of the multiple bottom rods to tighten. The multiple bottom rods are pushed toward the middle and compress the spring at the same time. At this time, the self-locking of the moving frame and the screw ensures the stability of the moving frame, thereby ensuring the stability of the pulling rope. The bottom rod after position adjustment still has the restraining force of the pulling rope and the spring. The interaction of the two sets of restraining forces ensures the stable position of the bottom rod, so that the spacing between the multiple bottom rods and the suction cup assembly at the bottom can be adjusted according to the use requirements, thereby improving the use effect of the automatic loading and unloading manipulator equipment of the laser marking machine.

[0028] 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.

[0029] See also Figure 1-7 , the present invention provides a technical solution:

[0030] A laser marking machine automatic loading and unloading manipulator device, comprising a mounting frame 1, a translation truss 2, a support frame 3 and a suction cup assembly, a telescopic cylinder 4 is fixedly mounted on the top of the support frame 3, a base 7 is hinged at the output end of the telescopic cylinder 4, when the outer frame 5 is kept in a straight state, the telescopic cylinder 4 pushes the base 7 to move downward, and the base 7 drives the suction cup assembly to move downward through the bottom rod 8 at the bottom, and the suction cup assembly can be directly adsorbed on the top of the product;

[0031] The outer wall of the telescopic cylinder 4 is slidably connected with a sliding sleeve 14, and the sliding sleeve 14 is rotatably connected with the outer frame 5 through a pin rod 15. The bottom of the outer frame 5 is hinged with a connecting rod 16 and a connecting rod 2 13. The outer walls of the connecting rod 16 and the connecting rod 2 13 are slidably connected to the inner wall of the support frame 3, and the bottom is hinged with the top of the base 7. A connecting seat 17 is fixedly installed at the bottom of the sliding sleeve 14, and a driving rod 18 is engaged and connected with the inner wall of the connecting seat 17. A positioning component for limiting the driving rod 18 is arranged on the outer side of the driving rod 18, and a turntable 19 is fixedly installed on the open end of the driving rod 18. A jacket 22 is hinged on the outer wall of the turntable 19, and a rotating sleeve 20 is rotatably connected to the inner wall of the connecting seat 17 through a pin shaft. A light rod 21 and a bent rod 23 are fixedly installed on the outer wall of the rotating sleeve 20. The bent rod 23 swings axially, and a pushing component for adjusting the vertical position of the connecting rod 16 is arranged between the bent rod 23 and the connecting rod 16;

[0032] When there is an inclined surface on the top of the product, the swing frame 29 is manually moved to make its open end separate from the outer wall of the driving rod 18, and the driving rod 18 drives the turntable 19 to rotate. The rotation process of the turntable 19 will cause the outer sleeve 22 installed on the outer wall to change its position. The outer sleeve 22 slides along the outer wall of the light rod 21 and provides an axial driving force for the light rod 21. The light rod 21 drives the rotating sleeve 20 and the bent rod 23 to deflect axially. During the axial deflection of the bent rod 23, the slide groove 26 of the inner wall and the protrusion 25 slide and cooperate. The protrusion 25 drives the connecting rod 1 6 to adjust the vertical position through the ring sleeve 24. At this time, the connecting rod 1 6, the connecting rod 2 13, the outer frame 5 and the base 7 form a parallelogram structure until the angle between the outer frame 5 and the connecting rod 1 6 reaches the specified requirement. At this time, the multiple groups of bottom rods 8 and the suction cup components at their bottom are overall inclined.

[0033] It also includes: a contraction mechanism for annular contraction of the suction cup assembly, the contraction mechanism is composed of a spring 34, a bottom rod 8 and an extrusion assembly for annularly pushing multiple groups of bottom rods 8, the top of the bottom rod 8 is slidably matched with the inner surface wall of the bottom of the base 7, and the bottom is hinged with the suction cup assembly, and the spring 34 is fixedly connected between the bottom rod 8 and the inner surface wall of the base 7;

[0034] Since the bottom rod 8 and the suction cup assembly are rotationally matched, the multiple groups of suction cup assemblies at this time remain in a straight position, and then the telescopic cylinder 4 drives the base 7 downward, and one end of each suction cup assembly simultaneously contacts different positions of the inclined surface of the product, and then as the bottom rod 8 continues to descend, the suction cup assembly is gradually sucked onto the inclined surface, so that the overall suction cup assembly can be tilted according to usage requirements, so as to adapt to the transfer requirements of different products, thereby improving the application range of the automatic loading and unloading robot equipment of the laser marking machine.

[0035] Specifically, Figure 1 and Figure 7 As shown, the extrusion assembly includes a slide bar fixedly mounted on the inner surface wall of the bottom of the base 7, the outer surface wall of the slide bar is slidably matched with the outer surface wall of the bottom rod 8, a servo motor 9 is fixedly mounted on the top of the base 7, a splicing seat 32 is integrally formed on one side of the base 7, a screw rod 11 is fixedly mounted on the driving end of the servo motor 9, the outer surface wall of the screw 11 is screwed and connected with a moving frame 10, the vertical end of the moving frame 10 is slidably matched with the inner surface wall of the splicing seat 32 through a card slot 12, and a pushing sleeve 31 is fixedly mounted on the bottom of the moving frame 10, multiple groups of pull ropes 33 are wound around the outer surface wall of the bottom rod 8, and both ends of the pull rope 33 are fixedly mounted on the inner surface wall of the vertical end of the splicing seat 32 at the same time, and the inner surface wall of the pushing sleeve 31 is slidably matched with the outer surface wall of the pull rope 33;

[0036] The pull rope 33 is in a taut state, and cooperates with the reaction force of the upper spring 34 to achieve the stability of the position of the multiple groups of bottom rods 8. The servo motor 9 can be controlled to drive the screw 11 to rotate, and the outer wall of the screw 11 is screwed with the inner wall of the moving frame 10. At the same time, the moving frame 10 is axially limited by the card slot 12, so that the moving frame 10 will drive the pushing sleeve 31 to move. The inner wall of the pushing sleeve 31 slides with the outer wall of the pull rope 33, and at the same time, the pull rope part of the outer wall of the multiple groups of bottom rods 8 is tightened. The spring 34 is compressed while the moving frame 10 moves toward the middle due to the power. At this time, the self-locking of the moving frame 10 and the screw rod 11 ensures the stability of the moving frame 10, thereby ensuring the stability of the state of the pull rope 33. The bottom rod 8 after position adjustment is still subject to the constraints of the pull rope 33 and the spring 34 at the same time. The interaction of the two groups of constraints ensures the stability of the position of the bottom rod 8, so that the spacing between the multiple groups of bottom rods 8 and the suction cup assemblies at the bottom thereof can be adjusted according to usage requirements, thereby improving the use effect of the automatic loading and unloading robot equipment of the laser marking machine.

[0037] Specifically, Figure 5 and Figure 6 As shown, the positioning assembly includes a straight rod 28 connected to the outer wall of the seat 17 and an inner groove 27 arranged on the outer wall of the driving rod 18, and multiple groups of inner grooves 27 are distributed in a ring shape. The outer wall of the straight rod 28 is connected to a swing frame 29 in a clamping manner. A torsion spring 30 is fixedly installed between the outer wall of the swing frame 29 and the outer wall of the connecting seat 17. The outer wall of the swing frame 29 is fixedly installed with a lever and an insertion rod matching the inner groove 27;

[0038] It should be noted that the annular inner grooves 27 are distributed in a partial area of ​​the driving rod 18, and do not completely penetrate the driving rod 18;

[0039] After the driving rod 18 is rotated, the swing frame 29 is released, and the swing frame 29 is reset under the action of the torsion spring 30 , and the insertion rod is engaged in the inner groove 27 at the specified position, thereby locking the driving rod 18 .

[0040] Specifically, Figure 2 and Figure 7 As shown, the pushing assembly includes a ring sleeve 24 fixedly installed on the outer wall of the connecting rod 6, and a protrusion 25 is fixedly installed on the outer wall of the ring sleeve 24. The protrusion 25 is slidably connected to the inner wall of the bent rod 23 through a horizontally arranged slide groove 26. The moving frame 10 will drive the pushing sleeve 31 to move. The inner wall of the pushing sleeve 31 slides with the outer wall of the pull rope 33 and drives the pull rope part of the outer wall of the multiple groups of bottom rods 8 to tighten.

[0041] Specifically, Figure 1 and Figure 3As shown, a fixing strip 16 is integrally formed at the bottom of the sliding sleeve 14, and the bottom of the fixing strip 16 is fixedly connected to a connecting seat 17 by screws. The connecting seat 17 is located below the outer frame 5 and is spaced apart from the outer wall of the telescopic cylinder 4 to ensure that the connecting seat 17 works stably and does not produce movement conflicts with the telescopic cylinder 4 in the horizontal direction. The outer wall of the rotating sleeve 20 is integrally formed with the bent rod 23, and a connecting frame is fixedly installed on the outer wall of the rotating sleeve 20, and the inner wall of the connecting frame is fixedly connected to a light rod 21, and the length of the light rod 21 is greater than the diameter of the turntable 19, so that when the turntable 19 drives the outer sleeve 22 to move to the extreme positions on both sides, there is still margin on both sides of the light rod 21, thereby ensuring the stable movement of the outer sleeve 22.

[0042] Specifically, Figure 1 and Figure 4 As shown, the outer wall of the slide rod is fitted with the inner wall of the spring 34, the multiple groups of slide rods and the spring 34 respectively correspond to the multiple groups of bottom rods 8, and the multiple groups of slide rods and the spring 34 are distributed in a rectangular shape. The cross-section of the multiple groups of slide rods is a rectangular structure. The slide rods with a rectangular structure can limit the axial deflection of the bottom rod 8, and the outer walls of the multiple groups of bottom rods 8 are fixedly installed with clamping sleeves, and the inner walls of the multiple groups of clamping sleeves are slidably connected to the outer walls of the pull rope 33. The corners where the multiple groups of clamping sleeves and the push sleeves 31 contact the pull rope 33 are all arranged in an arc structure. The clamping sleeve is not shown in the figure. It is specifically used to vertically limit the pull rope 33 to prevent the pull rope 33 from vertical position deviation during the pulling process or after the base 7 is tilted.

[0043] Working principle: when the outer frame 5 remains straight, the telescopic cylinder 4 pushes the base 7 to move downward, and the base 7 drives the suction cup assembly to move downward through the bottom rod 8 at the bottom, and the suction cup assembly can be directly adsorbed on the top of the product. When there is an inclined surface on the top of the product, the swing frame 29 is manually moved to make its open end separate from the outer wall of the driving rod 18, and then the turntable 19 is driven to rotate by the driving rod 18. During the rotation of the turntable 19, the outer sleeve 22 movably installed on the outer wall of the outer sleeve 22 will change its position. The outer sleeve 22 slides along the outer wall of the light rod 21 and provides an axial driving force for the light rod 21. The light rod 21 drives the rotating sleeve 20 and the bent rod 23 to deflect axially, and the bent rod 23 During the axial deflection, the slide groove 26 of the inner wall slides with the protrusion 25, and the protrusion 25 drives the connecting rod 1 6 to adjust the vertical position through the ring sleeve 24. At this time, the connecting rod 1 6, the connecting rod 2 13, the outer frame 5 and the base 7 form a parallelogram structure until the angle between the outer frame 5 and the connecting rod 1 6 reaches the specified requirement. At this time, the multiple groups of bottom rods 8 and the suction cup assemblies at their bottom are tilted as a whole, but because the bottom rod 8 and the suction cup assemblies are rotationally matched, the multiple groups of suction cup assemblies at this time still maintain a straight device, and then the telescopic cylinder 4 drives the base 7 downward, and one end of each suction cup assembly contacts different positions of the inclined surface of the product at the same time, and then as the bottom rod 8 continues to descend, the suction cup assembly is gradually attracted to the inclined surface, so that the overall suction cup assembly can be tilted according to the use requirements, so as to adapt to the transfer requirements of different products, thereby improving the application range of the automatic loading and unloading manipulator equipment of the laser marking machine. The pull rope 33 is in a taut state, and the reaction force of the upper spring 34 is cooperated to achieve the position stability of the multiple groups of bottom rods 8. The servo motor 9 can be controlled to drive the screw rod 11 to rotate, and the outer wall of the screw rod 11 is screwed with the inner wall of the moving frame 10. At the same time, the moving frame 10 is axially limited by the card slot 12, so that the moving frame 10 will drive the pushing sleeve 31 to move, and the inner wall of the pushing sleeve 31 and the pulling rope 33 are in a taut state. The outer wall of the rope 33 slides together and tightens the rope portion of the outer wall of the multiple groups of bottom rods 8. The multiple groups of bottom rods 8 are pushed and move toward the middle while compressing the spring 34. At this time, the self-locking of the mobile frame 10 and the screw 11 ensures the stability of the mobile frame 10, thereby ensuring the stability of the rope 33. The bottom rod 8 after position adjustment is still subject to the restraint of the rope 33 and the spring 34 at the same time. The interaction of the two groups of restraints ensures the stability of the position of the bottom rod 8, so that the spacing between the multiple groups of bottom rods 8 and the suction cup assembly at the bottom can be adjusted according to the use requirements, thereby improving the use effect of the automatic loading and unloading manipulator equipment of the laser marking machine. The above description of the embodiments enables professionals and technicians in this field to implement or use the present invention. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention.Thus, the present invention will not be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
