[0049] Please refer to Figures 1 to 7 , Figure 2 which is a schematic structural diagram of a mechanical arm fastening device for a fat dissolving robot in an embodiment of the present utility model. The mechanical arm fastening device for a fat dissolving robot is arranged in the annular gap 3 between the collaborative robotic arm 1 and the fat dissolving instrument body 2, and includes: a shielding plate 4 and a plurality of connecting components 5. The shielding plate 4 includes a first half body 41 and a second half body 42 that are spliced with each other and detachably connected. Opposite sides of the first half body 41 and the second half body 42 are respectively provided with a first half hole 411 and a second half hole 421. The first half hole 411 and the second half hole 421 enclose an installation hole allowing the collaborative robotic arm 1 to pass through.

The plurality of connecting components 5 are used to connect the fat dissolving instrument body 2 and can be detachably connected to the first half body 41 and the second half body 42 respectively.

[0050] In this device, the first half body 41 and the second half body 42 are spliced with each other and detachably connected to form the shielding plate 4. The shielding plate 4 is covered on the collaborative robotic arm 1 through the installation hole formed by the enclosure of the first half hole 411 and the second half hole 421, and can shield the annular gap 3. The plurality of connecting components 5 are used to connect the fat dissolving instrument body 2 and can be detachably connected to the first half body 41 and the second half body 42 respectively, for detachably connecting the first half body 41 and the second half body 42 to the fat dissolving instrument body 2.

[0051] Compared with the prior art, by arranging the spliceable first half body 41 and second half body 42 to cover the annular gap 3, the annular gap 3 between the collaborative robotic arm 1 and the lipolysis instrument body 2 is blocked. At the same time, a detachable structure is provided between the first half body 41 and the second half body 42 and the lipolysis instrument body 2, which is convenient for users to install and disassemble, facilitating later maintenance and repair, and can solve the problem in the prior art that dust or impurities easily fall into the annular gap formed between the collaborative robot and the body shell during daily use, resulting in abnormal use of the lipolysis robot.

[0052] Further, as Figure 1 shown, in the prior art, one end of the collaborative robotic arm 1 is externally disposed on the lipolysis instrument body 2, and the other end of the collaborative robotic arm 1 extends and is connected to the inside of the lipolysis instrument body 2 and forms an electrical connection with the internal equipment of the lipolysis instrument body 2.

[0055] By providing the card slot 22 communicating with the through hole 21, and the shape of the card slot 22 is set to match the spliced first half body 41 and second half body 42, so that the circumferential inner wall of the card slot 22 can respectively abut against the first half body 41 or the second half body 42, achieving the purpose of restricting the relative sliding of the first half body 41 or the second half body 42 relative to the lipolysis instrument body 2 and improving the stability of the device.

[0056] In one embodiment, the depth of the card slot 22 is greater than the thickness of the first half body 41 or the second half body 42.

[0057] By setting the depth of the card slot 22 to be greater than the thickness of the first half body 41 or the second half body 42, the circumferential inner wall of the card slot 22 can increase the restriction on the first half body 41 and the second half body 42, improving the stability of the device operation.

[0058] In this embodiment, as Figure 7 shown, the connecting component 5 includes a first connecting piece 51 and a second connecting piece 52.

[0059] Through the detachable connection structure formed by the cooperation of the first connecting piece 51 and the second connecting piece 52, the connection between the first half body 41 and the second half body 42 and the body 2 of the lipolysis instrument can be realized.

[0060] In one embodiment, please refer to Figure 7 , both the first connecting piece 51 and the second connecting piece 52 have magnetism, and the first connecting piece 51 and the second connecting piece 52 can be attracted to each other by magnetic force.

[0063] As one implementation manner, as Figure 7 shown, a plurality of first fixing grooves 23 are formed in the card slot 22. The plurality of first fixing grooves 23 are symmetrically distributed around the axis of the through hole 21 in a central point manner. The first connecting piece 51 is arranged corresponding to the first fixing grooves 23 one by one, and one end of the first connecting piece 51 is connected to the first fixing groove 23 and the other end is arranged opposite to the second connecting piece 52.

[0064] The first connecting piece 51 is connected to the bottom inner wall of the card slot 22 through the first fixing groove 23.

[0065] As one implementation manner, as Figures 5 to 7 shown, the first half body 41 or the second half body 42 is provided with second fixing grooves 24 corresponding to the first fixing grooves 23. The second connecting piece 52 is arranged corresponding to the second fixing grooves 24 one by one, and one end of the second connecting piece 52 is connected to the first fixing groove 23 and the other end can be magnetically attracted to the first connecting piece 51.

[0068] The first connecting member 51 and the second connecting member 52 are respectively connected to the first fixing groove 23 and the second fixing groove 24 by means of adhesion.

[0069] Furthermore, here the first connecting member 51 and the second connecting member 52 can also be clamped in the first fixing groove 23 and the second fixing groove 24. Specifically, the cross-sectional area of the first fixing groove 23 is larger than the diameter of the first connecting member 51. The elastic clamping block is clamped between the inner wall of the first fixing groove 23 and the outer wall of the first connecting member 51, and the first fixing groove 23 and the first connecting member 51 are clamped tightly. Details will not be elaborated here.

[0070] In this embodiment, as Figure 7 shown, the collaborative robotic arm 1 is frustum-shaped. The diameter of the mounting hole is larger than the minimum diameter of the collaborative robotic arm 1 and smaller than the maximum diameter of the collaborative robotic arm 1. The robotic arm fastening device for the melt index robot further includes a seal 6. The seal 6 is elastic and is disposed between the circumferential outer wall of the collaborative robotic arm 1 and the circumferential inner wall of the mounting hole, and is in contact with the circumferential outer wall of the collaborative robotic arm 1 and the circumferential inner wall of the mounting hole respectively.

And the cross-sectional areas of the first half-ring 61 and the second half-ring 62 gradually increase in the direction away from the mounting hole.

[0073] By providing a structure with a gradually changing cross-sectional area, the first half-ring 61 and the second half-ring 62 can always be in contact with the circumferential outer wall of the collaborative robotic arm 1 respectively, improving the stability of the device.

[0074] For a better understanding of the present invention, the technical solutions of the present invention will be described in detail below in conjunction with Figures 2 to 7 :

[0075] The specific working process of the present utility model is as follows: The first half body 41 and the second half body 42 are spliced with each other and detachably connected to form a shielding plate 4. The installation hole formed by enclosing the first half hole 411 and the second half hole 421 of the shielding plate 4 covers the collaborative robotic arm 1 and can shield the annular gap 3. A plurality of connecting components 5 are used to connect the lipolysis instrument body 2 and can be detachably connected to the first half body 41 and the second half body 42 respectively, for detachably connecting the first half body 41 and the second half body 42 to the lipolysis instrument body 2. Compared with the prior art, by arranging the spliceable first half body 41 and second half body 42 to cover the annular gap 3, the annular gap 3 between the collaborative robotic arm 1 and the lipolysis instrument body 2 is shielded. At the same time, a detachable structure is provided between the first half body 41 and the second half body 42 and the lipolysis instrument body 2, which is convenient for the user to install and disassemble, and is convenient for later maintenance and repair.

[0076] During use, the user respectively places the first half body 41 and the second half body 42 on both sides of the collaborative robotic arm 1, then makes the first half ring 61 and the second half ring 62 respectively abut against the outer wall of the collaborative robotic arm 1, then adjusts the first half body 41 and the second half body 42 to form an integral body, and can be cooperatively clamped in the card slot 22. Finally, the first connecting piece 51 and the second connecting piece 52 are magnetically attracted to detachably connect the first half body 41 and the second half body 42 to the lipolysis instrument body 2 and shield the annular gap formed between the collaborative robot and the body shell.

[0077] Furthermore, during maintenance or repair, the user only needs to pick out the first half body 41 or the second half body 42 from the card slot 22 to separate the first connecting piece 51 and the second connecting piece 52, and then can conveniently complete the disassembly of the shielding plate 4, and the operation is simple.

[0078] Through the above structure, the present device can solve the problem in the prior art that dust or impurities easily fall into the annular gap formed between the collaborative robot and the body shell during daily use, resulting in abnormal use of the lipolysis robot.
