Description

Technical Field

[0001] The utility model relates to a handling mechanical arm, in particular to a material barrel handling mechanical arm for coating material processing, belonging to the technical field of coating material processing. Background Art

[0002] In the prior art, a utility model with application number 202222551101.0 discloses a transport robot arm. In order to solve the problem that the transport robot arm is a spring clamping type with a hairpin and can clamp limited size objects, a motor, a lead screw, a fixed clamp and a movable clamp are provided. When in use, the lead screw is started to rotate to drive the movable plate to move left and right, and the left connecting plate is driven to move left and right, thereby making the left connecting plate move away from or close to the right connecting plate, or releasing the object being transported, so that the left connecting plate and the right connecting plate clamp the object being transported to the left and right. Since the length of the lead screw is larger than the size of the two clamping plates in the circumferential direction, the size of the clamped object is increased.

[0003] Similar to the above application, there are still some shortcomings:

[0004] Since the shape of the material barrel is mostly cylindrical, the current robot arm can only clamp the side during the clamping process. Since the side is a cylindrical surface, the contact area between the material barrel and the material barrel is small. If the material barrels are stacked, they need to be erected, and the clamping stability is low at this time;

[0005] For this purpose, a material barrel handling robot arm for coating material processing is designed to optimize the above-mentioned problems. Utility Model Content

[0006] The main purpose of the utility model is to provide a material barrel handling robot arm for coating material processing, which is composed of a clamping mechanism consisting of a fixed plate, a clamping claw, a cross bar and a cylinder, and the shape of the clamping claw is arc-shaped, which can increase the contact area with the outer wall of the material barrel and improve the stability of clamping. In addition, the limiting mechanism composed of a mounting plate, a slide groove, a spring and a protrusion can limit the end of the material barrel during the clamping process, ensuring the clamping stability of the material barrel under rotation adjustment at any angle, and has higher practicality. By arranging a telescopic mechanism composed of a motor, a gear, a through groove and a rack inside the fixed plate, the distance between the two sets of fixed plates can be adjusted according to the length of the material barrel during use, so as to limit material barrels of different lengths, which is more convenient to use.

[0023] In order to make the technical solution of the utility model more clear and specific to those skilled in the art, the utility model is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the utility model are not limited thereto.

[0024] like Figure 1-Figure 4 As shown, this embodiment provides a material barrel handling robot arm for coating material processing, including a base 1 and a robot arm 2 installed on the top of the base 1, a fixed plate 3 is installed on the movable end of the top of the robot arm 2, both sides of the fixed plate 3 are hingedly installed with clamping jaws 4, cross bars 5 are fixed on the clamping jaws 4, a cylinder 6 is hingedly installed on one side of the fixed plate 3 close to the clamping jaws 4, and the output end of the cylinder 6 is hinged to the cross bar 5, and both ends of the fixed plate 3 are slidably provided with a limiting mechanism 7 for positioning the end of the material barrel.

[0025] The overall working principle is as follows: before use, first fix the position of the base 1. When in use, control the angle of the robot arm 2, fit the clamp 4 on the outer wall of the material barrel, and then start the cylinder 6 to control the clamp 4 to clamp the outer wall of the material barrel. After clamping the material barrel, fit it on the end of the material barrel through the limiting mechanism 7, and clamp and limit the side and end of the material barrel at the same time to ensure the stability of the clamping.

[0026] In this embodiment, a flat plate is fixed to the bottom end of the base 1, and mounting holes are formed at four corners of the flat plate.

[0027] Local working principle: When the device is fixed, bolts are passed through the mounting holes and fixed to the base.

[0028] In this embodiment, the shape of the clamping jaw 4 is arc-shaped, and a rubber cushion layer is provided on the inner side of the clamping jaw 4 , and the bottom end of the clamping jaw 4 is provided with an upwardly inclined inclined surface.

[0029] Partial working principle: The arc-shaped clamping jaw 4 can increase the contact area with the material barrel, thereby improving the clamping stability, and the provision of the rubber pad layer increases the friction between the clamping jaw 4 and the material barrel.

[0030] In this embodiment, the limiting mechanism 7 includes a mounting plate 8, a slide groove 9, a protrusion 10 and a spring 11. The bottom of the mounting plate 8 is evenly provided with slide grooves 9, the inner top of the slide groove 9 is installed with a spring 11, the inside of the slide groove 9 is slidably installed with a protrusion 10, and the bottom end of the spring 11 is connected to the top end of the protrusion 10.

[0031] Local working principle: After the clamping jaws 4 clamp the material cylinder, the side of the material cylinder will fit against the outside of the fixed plate 3, the distance between the two sets of mounting plates 8 is greater than the length of the material cylinder, the material cylinder will also fit against the mounting plate 8, and squeeze the protrusion 10, compressing the protrusion 10 that fits the material cylinder into the inside of the slide groove 9, and the protrusion 10 on the outside of the end of the material cylinder is in an extended state, limiting the end of the material cylinder.

[0032] In this embodiment, the bottom end of the protrusion 10 is arc-shaped, and the length of the protrusion 10 protruding to the outside of the slide groove 9 is 2-5 cm.

[0033] Partial working principle: The arc-shaped design of the end of the protrusion 10 effectively avoids scratches on the surface of the material tube, and the limitation of the protruding length of the protrusion 10 can ensure the positioning of the end of the material tube.

[0034] In this embodiment, a motor 12 is installed at the middle position inside the fixed plate 3, a gear 13 is installed at the output end of the motor 12, through grooves 14 are symmetrically opened on both sides inside the fixed plate 3, and racks 15 are slidably arranged inside the through grooves 14. Two groups of racks 15 extend from both ends of the cylinder 6 respectively, the racks 15 are meshed with the gears 13, and the ends of the racks 15 away from the gears 13 are fixedly connected to the mounting plates 8 respectively.

[0035] Local working principle: During use, in order to limit the ends of material barrels of different lengths, the gear 13 is rotated by starting the motor 12. The gear 13 controls the two sets of racks 15 to slide toward or against each other, thereby changing the spacing of the mounting plates 8 to accommodate material barrels of different lengths.

[0036] In this embodiment, a limit block is fixed to one end of the rack 15 away from the mounting plate 8 .

[0037] Partial working principle: The use of the limit block can limit the sliding length of the rack 15 to prevent the rack 15 from excessively sliding out of the through slot 14.

[0038] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
