DETAILED DESCRIPTION

[0025] In order to make the technical problems, technical solutions and beneficial effects to be solved by the utility model clearer, the utility model is now described in detail in conjunction with the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the composition related to the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] refer to Figure 1 As shown, the robot arm 100 includes a suction cup arm 11, a suction cup seat 12 connected to the suction cup arm 11, and suction cups 13 distributed at intervals on the suction cup seat 12, and the suction cups 13 are funnel-shaped.

[0027] refer to Figure 2-4As shown, the utility model provides a cleaning assembly 200 for cleaning the loading and unloading mechanical arm of a laser cutting machine, comprising an assembly base 22 and a cleaning unit 21 installed at intervals on the assembly base 22, the cleaning unit 21 consisting of a motor 211, a motor output shaft 2111 vertically connected to the motor 211, a cleaning brush mounting shaft 215 coaxially mounted with the motor output shaft 2111, and a cleaning brush 216 mounted on the cleaning brush mounting shaft 215, the motor 211 being fixed to the assembly base 22 by a motor mounting plate 212 and a bolt 213. When in use, the suction cup 13 is moved to the top of the cleaning brush 216, so that the inner surface of the suction cup 13 is sleeved on the cleaning brush 216, and the motor 211 drives the cleaning brush 216 to rotate through the motor output shaft 2111 and the cleaning brush mounting shaft 215, so that the dust attached to the suction cup 13 is cleaned off.

[0028] The size and shape of the component base 22 match those of the suction cup seat 12 , and the distribution of the cleaning unit 21 on the plane of the component base 22 matches that of the suction cup 13 on the plane of the suction cup seat 12 , that is, the cleaning unit 21 can correspond one-to-one to the suction cup 13 .

[0029] In some embodiments, if the cleaning speed is not considered and the cost of the cleaning component 200 is considered, the cleaning component 200 can only be installed with one cleaning unit 21, and the different suction cups 13 can be cleaned by moving the robot arm 100.

[0030] In some embodiments, taking into account the cleaning speed and the manufacturing cost of the cleaning assembly 200, the cleaning assembly 200 can be installed with a row or a column of cleaning units 21, so that one row or a column of the suction cups 13 can be cleaned each time.

[0031] refer to Figure 5-7 As shown, the cleaning brush mounting shaft 215 is cylindrical, and is provided with a plurality of protrusions 2151 at one end close to the brush head. The protrusions 2151 are symmetrically arranged along the axis of the cleaning brush mounting shaft 215. A through hole (not shown in the figure) is provided in the protrusion 2151. The through hole passes through the protrusion 2151 and the mounting shaft 215. A spring pin 2152 is installed in the through hole. Preferably, there are two protrusions.

[0032] The spring pin 2152 is composed of two balls 21521 connected by a spring 21522. The natural length of the spring pin 2152 (i.e., the spring is not in a squeezed or stretched state) minus the length D of the through hole on the mounting shaft 215 is slightly smaller than the diameter of the ball 21521, preferably D = 0.8-0.9 times the diameter of the ball, which is convenient for installation and disassembly.

[0033] refer to Figure 8-9As shown, the cleaning brush 216 is composed of a brush disc 2161, a brush head 2162 installed on one side of the brush disc 2161 and a brush disc seat 2163 installed on the other side of the brush disc 2161. The brush disc seat 2163 is a hollow cylindrical boss. The brush disc seat 2163 matches the cleaning brush mounting shaft 215. The inner surface of the brush disc seat 2163 is the inner wall of the brush disc seat (not shown in the figure). A plurality of brush disc seat assembly grooves 21632 are provided along the inner wall of the brush disc seat. A spring pin groove 21633 is provided in the brush disc seat assembly groove 21632. The spring pin groove 21633 is hemispherical with a depth of 0.4-0.45 times the diameter of the ball 21521, so that the ball 21521 on the spring pin 2152 can be accommodated, and the installation and disassembly of the spring pin 2152 is also convenient. The number of the brush disc seat assembly grooves 21632 is the same as the number of the protrusions 2151 and their positions are corresponding. When the cleaning brush 216 is installed on the cleaning brush installation shaft 215, the protrusions 2151 can correspond one-to-one with the brush disc seat assembly grooves 21632.

[0034] refer to Figure 8 As shown, the brush head 2162 is composed of a plurality of cylindrical rubber blocks, forming a circle of concentric circles from the inside to the outside, and the height of the brush head gradually decreases from the inside to the outside, forming an inverted funnel shape, which is conducive to fitting with the funnel-shaped inner wall of the suction cup 13. There is a certain installation spacing between the brush heads 2162, and the spacing size is 2-3 times the diameter of the brush head 2162, so that the cleaned dust and debris can fall naturally on the brush plate 2161 under gravity.

[0035] refer to Figure 8 As shown, the brush plate 2161 is provided with a plurality of brush head mounting holes, and the brush head 2162 can be installed in the brush head mounting hole by interference fit, and the ratio of the depth of the brush head mounting hole to the height of the brush head 2162 is 1:4-10, which can ensure the stable operation of the brush head 2162 while saving the thickness of the brush plate 2161. During use, if individual brush heads 2162 are worn, they can be replaced separately.

[0036] After the robot arm has been used for a long time, or after grabbing a dirty plate, the cleaning component 200 is placed at the position of the plate to be grabbed, the robot arm 100 is controlled to make the inner surface of the suction cup 13 fit with the brush head 2162, and the motor 11 is started to drive the brush head 2162 to rotate, so that the debris on the inner wall of the suction cup 13 can be cleaned.

[0037] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection, it can be a mechanical connection, it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
