[0002] As we all know, air-conditioned clothing has two small fans installed on the left and right waist of a person's top, which draw outdoor air into the clothes. The heat of vaporization that evaporates sweat absorbs the heat on the body surface, cooling the body. It is a product that makes people feel cool and comfortable, so air-conditioned clothing cannot be used without fans.

[0003] At present, the fan used in air-conditioning clothes is 200 Figure 1 As shown, it is mainly composed of a fan body 210 and an upper cover 220 that is tightly fitted with the fan body 210; and the fan body 210 is composed of a bottom cover 211 and fan blades 212 assembled and connected to the bottom cover 211.

[0031] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings.

[0032] See also Figure 2 and Figure 4 The fan twist cover assembly labeling machine 100 of the present invention comprises a frame 10, a rotary conveyor line 20, a pressing mechanism 30, a positioning die base 40, a feeding conveyor line 50, a feeding twist cover manipulator 60, a labeling mechanism 70a, a unloading conveyor line 70b and an unloading manipulator 80; optionally, Figures 2 to 4 In the embodiment, as an example, the frame 10 is a square. Obviously, according to actual needs, the frame 10 can also be other shapes known in the art. Figures 2 to 4 Limits shown.

[0033] Recombination Figures 5 to 8 , the rotary conveyor line 20 is mounted on the frame 10, and the frame 10 provides support for the rotary conveyor line 20. The rotary conveyor line 20 includes a rotary chain 21, a rotary driver 22 that drives the rotary chain 21 to perform horizontal rotary motion, a plurality of support seats 23 that are spaced apart and arranged along the rotary direction of the rotary chain 21 and are used to carry the fan body 210, and a positioning driver 24 that is located below the corresponding support seat 23 and is arranged up and down. The support seat 23 is provided with a matching structure 231 located next to the outer side of the rotary chain 21, and the output end 241 of the positioning driver 24 is equipped with a positioning structure 242 for positioning and cooperating with the matching structure 231; optionally, in combination with Figure 4 and Figure 5As an example, the matching structure 231 is a column arranged flat, and the positioning structure 242 is a positioning groove with a notch facing upward; this design makes the engagement or separation between the positioning structure 242 and the matching structure 231 smoother and more convenient; in addition, the output end 241 of the positioning driver 24 is arranged upward to simplify the assembly relationship between the output end 241 of the positioning driver 24 and the positioning structure 242; obviously, according to actual needs, the specific structures of the matching structure 231 and the positioning structure 242 and the orientation of the output end 241 of the positioning driver 24 can also be other, so it is not used here. Figure 5 Limits shown.

[0034] The pressing mechanism 30 includes a first pressing assembly 31 located beside the inner side of the rotary chain 21 and a second pressing assembly 32 located beside the outer side of the rotary chain 21 and arranged opposite to the first pressing assembly 31; when the positioning structure 242 and the matching structure 231 are positioned and matched, the second pressing assembly 32 and the first pressing assembly 31 together clamp the fan body 210 on the corresponding supporting seat 23 to prepare for the tightening fit of the fan body 210 and the upper cover 220; optionally, Figure 4 As an example, the first pressing assembly 31 and the second pressing assembly 32 have the same structure, both of which include a pressing cylinder and a pressing block mounted on the output end of the pressing cylinder, so as to simplify the structure of the first pressing assembly 31 and the second pressing assembly 32; obviously, according to actual needs, the specific structure of the first pressing assembly 31 and the second pressing assembly 32 can also be other structures well known in the art, so it is not repeated here; in addition, the first pressing assembly 31 and the second pressing assembly 32 are also assembled and connected with the frame 10. In addition, it should be noted that at this time, the "corresponding support seat 23" refers to the support seat 23 that follows the rotary chain 21 to come between the first pressing assembly 31 and the second pressing assembly 32.

[0035] The positioning die holder 40 is arranged beside the second pressing assembly 32 on the side facing away from the rotary chain 21. Figure 4 As shown; the positioning mold base 40 is provided with a positioning structure 41 for positioning the upper cover 220, the state is shown Fig.10 as shown; optionally, Fig.10 As an example, the positioning structures 41 are two spaced apart from each other, so that the positioning mold base 40 can position two upper covers 220 at a time; obviously, according to actual needs, the number of the positioning structures 41 can also be one or three, so it is not limited to Fig.10 In addition, the positioning mold base 40 is also assembled and connected with the frame 10.

[0036] The feeding conveyor line 50 is arranged beside the side of the positioning die holder 40 facing away from the second pressing assembly 32. Figure 3As shown; the feeding conveyor line 50 is used to convey the upper cover 220 toward the direction close to the positioning mold base 40 to meet the need for automatic feeding of the upper cover 220 to the positioning mold base 40; optionally, Figure 2 and Figure 3 In the embodiment, as an example, the feeding conveyor line 50 is a belt conveyor line. Obviously, according to actual needs, the feeding conveyor line 50 can also be other conveyor lines. Figure 2 and Figure 3 Limits shown.

[0037] The loading and capping robot 60 spans over the loading conveyor line 50, the positioning mold base 40 and the rotating chain 21. The loading and capping robot 60 is used to transfer the upper cover 220 conveyed by the loading conveyor line 50 to the positioning structure 41. At the same time, the loading and capping robot 60 also transfers the upper cover 220 at the positioning structure 41 to the fan body 2110 clamped by the first pressing assembly 31 and the second pressing assembly 32, and tightens the upper cover 220 with the fan body 210 to obtain the fan 200; optionally, as an example, the loading and capping robot 60 is also assembled and connected to the frame 10.

[0038] The labeling mechanism 70a is arranged beside the outer side of the rotary chain 21 and is adjacent to the loading and capping robot 60 along the rotating direction of the rotary chain 21. The labeling mechanism 70a is used to attach labels to the upper cover 220 of the fan 200 conveyed by the rotary chain 21, so as to achieve the purpose of automatically labeling the upper cover 220 of the fan 200 that follows the rotary chain 21 to the labeling mechanism 70a; optionally, as an example, the labeling mechanism 70a is also assembled and connected to the frame 10.

[0039] The unloading conveyor line 70b is arranged on the other side of the rotary chain 21, so that the unloading conveyor line 70b is arranged opposite to the loading conveyor line 50, thereby meeting the operation needs of loading from one side of the rotary chain 21 and unloading from the other side. Figure 2 and Figure 3 as shown; optionally, Figure 2 and Figure 3 In the embodiment, as an example, the unloading conveyor line 70b is a belt conveyor line. Obviously, according to actual needs, the unloading conveyor line 70b can also be other conveyor lines. Figure 2 and Figure 3 in addition, the unloading conveyor line 70b and the loading conveyor line 50 are arranged in horizontal straight lines so that they are parallel to each other.

[0040] The unloading robot 80 spans the unloading conveyor line 70b and the rotary chain 21, and is used to transfer the labeled fan 200 conveyed by the rotary chain 21 to the unloading conveyor line 80, and the unloading conveyor line 80 delivers the fan 200 to meet the needs of the fan twist cover assembly labeling machine 100 of the present invention. More specifically, as follows:

[0041] like Figures 5 to 8 As shown, as an example, the fan twist cover assembly labeling machine 100 of the present invention also includes a circular guide rail 90 mounted on the frame 10 and arranged around the rotating chain 21, and a circular groove 91 arranged around the rotating chain 21 is provided on the outer wall of the circular guide rail 90; the supporting seat 23 is correspondingly equipped with a guide roller 232 embedded in the circular groove 91 and rolling along the circular groove 91; with the help of the cooperation between the guide roller 232 and the circular groove 91, on the one hand, the supporting strength of the supporting seat 23 is increased, and on the other hand, the smoothness and stability of the supporting seat 23 following the rotating chain 21 to make a rotating motion are improved, thereby avoiding defects such as jamming and jumping during the rotation process. Specifically, Fig. 9 As an example, the guide rollers 232 on the support seat 23 are two and are arranged spaced apart from each other along the rotation direction of the rotary chain 21; obviously, according to actual needs, the guide rollers 232 on the support seat 23 can also be three or four. Fig. 9 The figure is limited to that shown; in addition, the matching structure 231 on the supporting seat 23 is located between the guide rollers 232 on the supporting seat 23 along the rotation direction of the rotating chain 21, so as to effectively improve the accuracy of the positioning of the supporting seat 23 by the positioning driver 24. In addition, each supporting seat 23 corresponds to a positioning driver 24, and each positioning driver 24 is equipped with a positioning structure 242 on the output end 241; such a design can be positioned from various positions in the rotation direction of the rotating chain 21, so as to better meet the positioning of the corresponding supporting seat 23 before the loading and twisting of the cap mechanism hand 60, the labeling mechanism 70a before labeling, and the unloading robot 80 before unloading, thereby improving the working reliability of the fan twisting cap assembly labeling machine 100 of the present invention. More specifically, in Figure 5 As an example, the frame 10 is further provided with a covering plate 11 for covering the rotating chain 21 from above, so that the covering plate 11 can be used to prevent materials from falling into the rotating chain 21 from above, and prevent the rotating chain 21 from getting stuck or even damaged during the rotation process due to falling into the rotating chain 21.

[0042] like Figure 3 , Figure 4 , Fig.10 and Fig.11As shown, as an example, the loading and capping robot 60 includes a horizontal transfer module 61, a horizontal slide 62, a first lifting assembly 63 mounted on one side of the horizontal slide 62, a grabbing assembly 64 mounted on the first lifting assembly 63, a second lifting assembly 65 mounted on the other side of the horizontal slide 62, and a capping assembly 66 mounted on the second lifting assembly 64. The horizontal transfer module 61 spans over the loading conveyor line 50, the positioning mold base 40, and the rotary chain 21; such a design allows the grabbing assembly 64 to be driven by the horizontal transfer module 61 through the horizontal slide 62 to come directly above the upper cover 220 conveyed by the loading conveyor line 50, and the capping assembly 66 at this time comes to be directly above the positioning structure 41 of the positioning mold base 40, thereby satisfying the grabbing assembly 64 to grab the upper cover 200 conveyed by the loading conveyor line 50 and the capping assembly 66. 6 is synchronous with the grabbing of the fan body 210 positioned by the positioning structure 41; similarly, when the grabbing assembly 64 is driven by the horizontal transfer module 61 through the horizontal slide 62 to come to the top of the positioning structure 41, the cover twisting assembly 66 comes to the top of the corresponding support seat 23, so that the grabbing assembly 64 places the upper cover 220 on the positioning structure 41 and the cover twisting assembly 66 tightens the grabbed upper cover 220 to the fan body 210 synchronously; thus improving the work efficiency. Specifically, at Fig.10 and Fig.11 As an example, the frame 10 is provided with a first support frame 12 located beside one side of the positioning mold base 40 and a second support frame 13 located beside the other side opposite to the positioning mold base 40, and the first support frame 12 and the second support frame 13 are both higher than the positioning mold base 40; the horizontal transfer module 61 is assembled on the top of the first support frame 12, and the top of the second support frame 13 is provided with a horizontal guide rail 14, and the horizontal slide 62 is located above the positioning mold base 40 and is slidably connected to the horizontal guide rail 14. This design allows the horizontal slide 62 to move in the relative direction between the first support frame 12 and the second support frame 13 (see Fig.10The two sides of the upper cover 220 (indicated by the double arrow E) are supported, thereby improving the supporting capacity of the horizontal slide 62 to the first lifting assembly 63, the grabbing assembly 64, the second lifting assembly 65 and the twisting cover assembly 66, thereby ensuring the reliability of the operation of the first lifting assembly 63, the grabbing assembly 64, the second lifting assembly 65 and the twisting cover assembly 66; in addition, the grabbing assembly 64 and the twisting cover assembly 66 are two separated and arranged in the relative directions of the first supporting frame 12 and the second supporting frame 13, so as to improve the transfer efficiency of the upper cover 220 and the twisting cover effect of the upper cover 220; the grabbing assembly 64 and the twisting cover assembly 66 are both located in the gap 15 surrounded by the first supporting frame 12 and the second supporting frame 13, and the first supporting frame 12 and the second supporting frame 13 provide protection for the operation of the grabbing assembly 64 and the twisting cover assembly 66. For example, the horizontal transfer module 61 and the second lifting assembly 65 are each a structure composed of a motor, a screw rod and a nut, the first lifting assembly 63 is a structure composed of a cylinder or a hydraulic cylinder; the grabbing assembly 64 is a pneumatic clamping finger, and the twisting cover assembly 66 is a structure composed of a motor, a screw rod, a nut and a pneumatic clamping finger, but is not limited to this.

[0043] like Fig.12 As shown in FIG. 1 , as an example, the unloading robot 80 includes a horizontal transfer mechanism 81 across the unloading conveyor line 70b and the rotary chain 21, a lifting mechanism 82 mounted on the horizontal transfer mechanism 81, and a gripping mechanism 83 mounted on the lifting mechanism 82. The gripping mechanism 83 is suspended on the horizontal transfer mechanism 81 by means of the lifting mechanism 82. Fig.12 As shown; this design makes the unloading robot 80 a structure with three degrees of freedom of X, Y and Z; for example, the horizontal transfer mechanism 81 is a structure composed of a motor, a screw rod and a nut, the lifting mechanism 82 is a structure composed of a cylinder or a hydraulic cylinder, and the grasping mechanism 83 is a structure composed of pneumatic clamping fingers, but it is not limited to this.

[0044] Compared with the prior art, since the feeding cover twisting manipulator 60 transfers the upper cover 220 delivered by the feeding conveyor line 50 to the positioning structure 41, it also transfers the upper cover 220 at the positioning structure 41 to the fan body 210 clamped by the first pressing assembly 31 and the second pressing assembly 32, so the synchronization is good and the efficiency is high; more importantly, the feeding cover twisting manipulator 60 first positions the support seat 23 on the rotary chain 21 and the fan body 210 on the support seat 23 is pressed by the pressing machine before the fan body 210 and the upper cover 220 are tightened together. The upper cover 220 and the fan body 210 are clamped by the structure 30, which effectively ensures the accuracy and reliability of the positions of the two before they are tightened, thereby improving the twisting cover assembly quality of the upper cover 220 and the fan body 210; similarly, before the labeling mechanism 70a labels the upper cover 220 of the fan 200 on the supporting seat 23 transported by the rotating chain 21 and before the labeled fan 200 is transferred to the unloading conveyor line 70b, the positioning driver 24 fixes the supporting seat 23 through the cooperation of the positioning structure 242 and the matching structure 231, thereby improving the accuracy and reliability of automatic labeling and automatic unloading.

[0045] It is additionally noted that the positioning driver 24 may be a cylinder or a hydraulic cylinder; in addition, the fan body 210 supported by the support seat 23 may be placed on the support seat 23 by an external manipulator, which is located at a position 16 (see FIG. 16 ) between the top pressing mechanism 30 and the unloading manipulator 80 from the rotary chain 21. Figure 4 ) to carry out loading operation.

[0046] The above disclosure is only a preferred embodiment of the present invention, which is to facilitate the understanding and implementation of the present invention by those skilled in the art. It certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
