[0023] The technical features of the present invention are further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As shown in the figure, the utility model is a robot automatic hot plug device, which is installed on a robot workbench. The robot workbench includes a workbench base 901, on which a cover clamping seat 902, a collaborative robot 903, a vibration plate 904, and a heating chamber 905 are installed.

[0025] The collaborative robot 903 is installed on one side of the cover clamping seat 902. The cover clamping seat 902 is provided with a clamping cylinder 906. The piston movement direction of the clamping cylinder 906 is perpendicular to the upper end of the workbench base 901. A lower pressure plate is fixed to the piston end of the clamping cylinder 906. The cover workpiece is pressed onto the cover clamping seat 902 by the lower pressure plate to fix the cover workpiece. A plurality of positioning blocks are provided on the cover clamping seat 902. The positioning blocks can be close to the side of the cover workpiece to position the cover workpiece.

[0026] The robot automatic hot-plug device of the present application is installed at the end of the manipulator of the collaborative robot 903.

[0027] Among them, the vibration plate 904 is an auxiliary feeding device for automatic assembly or automatic processing machinery. It can arrange various products in an orderly manner. There is a pulse electromagnet under the hopper of the vibration plate 904, which can make the hopper vibrate in the vertical direction, and the inclined spring sheet drives the hopper to do torsional vibration around its vertical axis. The parts in the hopper rise along the spiral track due to this vibration. During the rising process, after a series of track screening or posture changes, the parts can automatically enter the assembly or processing position in a unified state according to the requirements of assembly or processing. Its working purpose is to automatically and orderly arrange the disordered workpieces in a directional and accurate manner through vibration and transport them to the next process.

[0028] Heating chamber 905 is used to heat the nuts, and the heating is done by two heating rods, specifically MISUMI brand, model C-MCH12-250-W1300. After the nuts are heated, the push cylinder drives the slider and the push rod to the material removal position, and the robot drives the material removal head to the material removal position to remove the nuts.

[0029] A control system is installed on one side of the workbench base 901 for controlling the opening of the air valve to blow air to cool the installed nuts.

[0030] The heating chamber 905 and the vibration plate 904 are both common structures in the prior art and will not be described in detail here.

[0031] The robot automatic hot-plug device of the present application comprises a tail end connecting portion and a nut clamping portion, wherein the nut clamping portion is installed at the end of the tail end connecting portion.

[0032] The nut clamping part includes a plug-in end 1, a hot plug rod 2, a displacement sleeve 3, a pressure sensor 4, a displacement sensor 5, a connecting column 6 and an adapter plate 7.

[0033] The hot plug rod 2 is installed on the tail end connection part. The plug end 1 is connected to the hot plug rod 2 and has a reduced diameter gap at the end; the plug end 1 is inserted into the nut and clamps the nut. The displacement sleeve 3 is sleeved on the hot plug rod 2, and when the plug end 1 is inserted into the nut, the displacement sleeve 3 is pushed to move along the axial direction of the hot plug rod 2.

[0034] The plug-in end 1 is an elastic metal column, and the reduced diameter gap at the end of the plug-in end 1 is arranged along the axial direction of the plug-in end 1, forming a straight or cross-shaped slit at the end of the plug-in end 1. When the plug-in end 1 is inserted into the nut, the reduced diameter gap shrinks so that the outer diameter of the end of the plug-in end 1 changes, and the nut is fixed at the end of the plug-in end 1 by the elastic restoring force of the plug-in end 1. In order to facilitate insertion, the end of the plug-in end 1 away from the tail end connection is constructed as a cone.

[0035] A pressure sensor 4 is provided between the hot plug rod 2 and the tail end connection portion, and the end of the hot plug rod 2 is connected to the pressure detection end of the pressure sensor 4 .

[0036] The side of the displacement sleeve 3 has an extension end, which is arranged in cooperation with the displacement detection end of the displacement sensor 5. In this embodiment, the displacement sensor 5 is a laser displacement sensor. The tail end connection part includes a robot connection column 6 and an adapter plate 7, and the nut clamping part is connected to the robot connection column 6 through the adapter plate 7; one side of the adapter plate 7 has a mounting block 701, and the displacement sensor 5 is connected to the adapter plate 7 through the mounting block 701.

[0037] One end of the hot plug rod 2 connected to the pressure sensor 4 is an expanded end; a spring 8 is provided between the expanded end of the hot plug rod 2 and the displacement sleeve 3, and both ends of the spring 8 are in contact with the expanded end of the hot plug rod 2 and the displacement sleeve 3 respectively.

[0038] Working steps of the robot workbench:

[0039] The cover is manually placed in place on the cover clamping seat 902, and the clamping cylinder 906 on the cover clamping seat 902 clamps the cover workpiece. The collaborative robot 903 drives the robot automatic hot-plugging device of the present application to take nuts from the nut heating bin feeding port, one at a time, and then drives the nuts on the robot automatic hot-plugging device of the present application to the top of the nut holes to be installed on the cover workpiece, and then drives the nuts on the robot automatic hot-plugging device of the present application to be pressed down into place. The control system controls the air valve to open and blows air to cool the nuts. The collaborative robot 903 drives the robot automatic hot-plugging device of the present application to repeat the action to take nuts from the feeding port of the heating bin 905 until the hot plugging of multiple nuts is completed, and the clamping cylinder 906 on the cover clamping seat 902 opens, and the worker takes out the cover.

[0040] The working steps of the robot automatic hot plug device of this application are as follows

[0041] The parts of the robot automatic hot-plugging device of the present application are connected by bolts. When working, the collaborative robot 903 drives the robot automatic hot-plugging device of the present application to the discharge port of the heating chamber 905. The outer diameter of the plug-in end 1 is larger than the inner diameter of the hot-plug nut. When the plug-in end 1 goes down to take the material, the outer diameter of the plug-in end 1 is compressed and deformed and maintains elasticity, so that the hot-plug nut is taken onto the plug-in end 1.

[0042] The displacement sleeve 3 is slidable relative to the hot plug rod 2. When the robot automatic hot plug device of the present application presses down on the cover product to perform hot plugging, the displacement sleeve 3 slides on the surface of the cover product, and the displacement sensor 5 detects the sliding distance of the displacement sleeve 3 in real time, which can control the insertion depth of the hot plug nut. The pressure sensor 4 can detect the downward pressure of the hot plug rod 2, thereby controlling the downward pressure to prevent the hot plug nut from being inserted too deep.

[0043] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by ordinary technicians in this technical field within the essential scope of the present invention should fall within the protection scope of the present invention.
