[0036] An alcohol-dipping mechanism 4 is provided between the joint assembly device 3 and the joint loading device 2. The joint assembly device 3 includes a second rotating indexing plate 31 and a positioning mechanism 32. The second rotating indexing plate 31 is positioned adjacent to the first rotating indexing plate 11. The positioning mechanism 32 is used to position the semi-finished face mask. The joint transport mechanism 23 is used to transport the reversing joint to the alcohol-dipping mechanism 4 for dipping in alcohol before assembling the joint with the semi-finished face mask on the second indexing plate. The finished product unloading device 5 includes a finished product transport mechanism 51 and a finished product conveyor line 52. The finished product transport mechanism 51 is used to transport the face mask with the joint installed to the finished product conveyor line 52.

[0037] Specifically, the semi-finished mask is loaded onto the first rotating indexing plate 11, and the first rotating indexing plate 11 can drive the semi-finished mask to rotate to a preset position, so as to facilitate the mask conveying mechanism 12 to convey the semi-finished mask to the second rotating indexing plate 31 of the joint assembly device 3, and the second rotating indexing plate 31 can drive the semi-finished mask to rotate to be opposite to the joint feeding device 2, and the mask loaded on the second rotating indexing plate 31 is positioned by the positioning mechanism 32, and the vibration disk mechanism 21 realizes the vibration feeding of the elbow joint. During the process, the elbow joints can be arranged neatly, and then transferred to the position of the reversing mechanism 22. The reversing mechanism 22 rotates the elbow joints by a certain angle so that the joint conveying mechanism 23 can convey the elbow joints to the alcohol dipping mechanism 4. After dipping in alcohol, the joints are assembled with the semi-finished masks on the second dividing plate. The finished masks with assembled joints are conveyed to the finished product conveyor line 52 through the finished product conveying mechanism 51, thus realizing automated conveying, assembly and unloading, which can ensure the accuracy and consistency of assembly, and at the same time ensure the cleanliness of assembly without manual labor.

[0038] In the above embodiment, an in-position sensor is installed on the first rotating indexing plate 11. After the in-position sensor detects that the semi-finished mask is in position, the mask conveying mechanism 12 conveys the semi-finished mask to the second rotating indexing plate 31 of the joint assembly device 3.

[0039] like Figures 1 to 3 As shown, in some embodiments, the first rotating indexing plate 11 includes a first turntable 111 and a plurality of first positioning molds 112. The plurality of first positioning molds 112 are evenly spaced and arranged on the first turntable 111 along the circumferential direction, and the semi-finished face mask is placed on the first positioning molds 112. The first turntable 111 and the first positioning molds 112 evenly spaced and arranged on the first turntable 111 can ensure the stability and accuracy of the semi-finished face mask during the rotation process, so that the semi-finished face mask can be accurately positioned, which facilitates the face mask handling mechanism 12 to handle it. The first positioning molds 112 match the shape of the semi-finished face mask to effectively support the semi-finished face mask.

[0040] like Figure 4As shown, in some embodiments, the mask transport mechanism 12 includes a first transverse servo drive assembly 121, a sliding assembly 122, and a gripping assembly 123. The sliding assembly 122 is vertically connected to the first transverse servo drive assembly 121, and the gripping assembly 123 is connected to the sliding assembly 122. Driven by the first transverse servo drive assembly 121, the sliding assembly 122 can smoothly move laterally, and the sliding assembly 122 can drive the gripping assembly 123 to rise and fall in the vertical direction, thereby transporting the semi-finished masks on the first rotating indexing plate 11 to the second rotating indexing plate 31.

[0041] like Figure 4 As shown, in some embodiments, the clamping assembly 123 includes a first clamping driver 1231, a first clamping block 1232, and a clamping block 1233. The first clamping block 1232 is connected to the two driving ends of the first clamping driver 1231. The two clamping blocks 1233 are respectively installed on the inner sides of the two first clamping blocks 1232. The clamping blocks 1233 are provided with arcuate grooves. The first clamping driver 1231 can be a finger cylinder. The two driving ends of the first clamping driver 1231 can drive the two first clamping blocks 1232 to move in opposite directions, thereby driving the clamping blocks 1233 to clamp or release the semi-finished mask. Since the clamped portion of the semi-finished mask is a cylindrical protrusion, the arcuate groove provided on the clamping block 1233 can more accurately and stably clamp and place the semi-finished mask.

[0042] like Figure 2 and Figure 5 As shown, in some embodiments, the vibration plate mechanism 21 includes a vibration plate assembly 211 and a straight vibration conveying assembly 212. The vibration plate assembly 211 is connected to the straight vibration conveying assembly 212, which is connected to the reversing mechanism 22. The straight vibration conveying assembly 212 includes a straight vibration plate 2121 and a pressure plate 2122, and the pressure plate 2122 is covered on the straight vibration plate 2121. The vibration plate assembly 211 realizes the flow of materials through vibration, thereby quickly feeding the elbow joints into the straight vibration conveying assembly 212. During the vibration process, the elbow joints can be arranged to ensure their uniform distribution. The elbow joints vibrate and move on the straight vibration plate 2121. The pressure plate 2122 is covered on the straight vibration plate 2121 to ensure that the elbow joints do not shift during the vibration process. In this way, a single elbow joint can be accurately reversed at the position of the reversing mechanism 22. The reversing mechanism 22 can rotate the flat elbow joint 90° for subsequent operation.

[0043] like Figure 5 and Figure 6As shown, in some embodiments, the reversing mechanism 22 includes a first rotary driving member 221, a connecting block 222, a material receiving member 223 and a material receiving block 224. The first rotary driving member 221 is connected to the connecting block 222, and the connecting block 222 is connected to the material receiving member 223. A material receiving groove 2231 is provided on the material receiving member 223, and the opening of the material receiving groove 2231 is connected to the direct vibration conveying assembly 212. A protruding structure 2232 is provided on both sides of the material receiving groove 2231. The material receiving block 224 is adjacent to the material receiving member 223 and cooperates with the material receiving member 223 to receive the joint. The first rotating driving member 221 can drive the connecting block 222 to rotate, and the connecting block 222 drives the material receiving member 223 to rotate. When the elbow joint is transported to the position of the reversing mechanism 22, the elbow joint will enter the material receiving member 223 through the opening on the material receiving groove 2231, and the other end will overlap on the material receiving block 224. After the elbow joint is in place, the material receiving member 223 rotates to rotate the elbow joint 90°. The raised structures 2232 on both sides of the material receiving groove 2231 are used to ensure the stability and accuracy of the rotation of the elbow joint.

[0044] like Figure 2 and Figure 5 As shown, in some embodiments, the joint handling mechanism 23 includes a second transverse servo drive assembly 231, a second rotary drive member 232, a sliding drive assembly 233, a second clamping drive member 234 and a second clamping block 235. The second rotary drive member 232 is installed on the second transverse servo drive assembly 231, the sliding drive assembly 233 is connected to the second rotary drive member 232, the second clamping drive member 234 is connected to the sliding drive assembly 233, the second clamping block 235 is connected to the two driving ends of the second clamping drive member 234, and the second clamping block 235 is provided with an arc-shaped groove 2351, and the groove 2351 is provided with an oblong first limiting groove 2352 and a second limiting groove 2353.

[0045] Specifically, the second clamping drive member 234 can be a finger cylinder, which can drive the two second clamping blocks 235 to move in opposite directions. The arc-shaped groove 2351 on the second clamping block 235 can match the shape of the clamping position of the elbow joint. In addition, the oblong first limit groove 2352 and the second limit groove 2353 are provided on the groove 2351 to ensure greater stability when clamping the elbow joint, and also to ensure stability when the elbow joint is installed. The second transverse servo drive assembly 231 can drive the second rotary drive member 232 to move smoothly laterally, thereby driving the sliding drive assembly 233 to move laterally. The second rotary drive member 232 can adjust the direction of the sliding drive assembly 233, thereby adjusting the direction of the elbow joint for more precise assembly. The sliding drive assembly 233 is used to drive the second clamping drive member 234 to rise and fall.

[0046] like Figure 2 and Figure 5As shown, in some embodiments, the alcohol-soaking mechanism 4 includes a mounting base 41, a lifting drive 42, and an alcohol cup 43. The lifting drive 42 is mounted on the mounting base 41, and the alcohol cup 43 is connected to the output end of the lifting drive 42. The lifting drive 42 can be a telescopic cylinder that can drive the alcohol cup 43 to a suitable height so that the elbow connector can contact the sponge soaked in oily alcohol in the alcohol cup 43. After the elbow connector is soaked in alcohol, the first transverse servo drive assembly 121 moves the sliding drive assembly 233, thereby transporting the alcohol-soaked elbow connector to the joint assembly device 3 for assembly of the elbow connector with the mask.

[0047] In the above embodiment, the position of the alcohol cup 43 can also be kept stationary, and the elbow joint can be driven down by the sliding drive component 233, so that the elbow joint can be inserted into the alcohol cup 43 to pick up alcohol, and then rise to the original height, and move to the joint assembly device 3 through the second transverse servo drive component 231.

[0048] like Figure 3 and Figure 7 As shown, in some embodiments, the second rotating indexing plate 31 includes a second turntable 311 and several second positioning molds 312, and the positioning mechanism 32 includes a fixed frame 321, two sets of tightening components 322 and a clamping component 323, the tightening component 322 and the clamping component 323 are installed on the fixed frame 321, the two sets of tightening components 322 are used to tighten the mask on the second positioning mold 312 close to the first rotating indexing plate 11 and the mask on the second positioning mold 312 close to the joint loading device 2, and the clamping component is used to clamp the mask rotated to the second positioning mold 312 close to the joint loading device 2.

[0049] After the mask transport mechanism 12 transports the semi-finished mask to the second positioning mold 312, one set of tightening components 322 performs the first positioning of the semi-finished mask, and the turntable rotates to rotate the second positioning mold 312 to a position close to the joint loading device 2. Another set of tightening components 322 performs the second positioning of the semi-finished mask, and at the same time, the clamping component 323 clamps the raised part of the mask to ensure the stability of the installation of the elbow joint.

[0050] like Figure 3 and Figure 7 As shown, in some embodiments, the tightening assembly 322 includes a pushing drive member 3221 and a clamping block 3222, and the clamping block 3222 is connected to the pushing drive member 3221; the clamping assembly 323 includes a third clamping drive member 3231 vertically installed on the fixed frame 321, and the two driving ends of the third clamping drive member 3231 are connected to the clamping plate 3232, and the clamping plate 3232 is provided with an arc-shaped clamping groove.

[0051] The clamping assembly 322 has two groups, one of which is inclined toward the second positioning mold 312 on the first rotating indexing plate 11, and the other is installed below the clamping assembly 323 and toward the direction of the mask on the second positioning mold 312 near the joint feeding device 2. The pushing drive 3221 drives the pressing block 3222 to move toward the second positioning mold 312 to tighten the mask on the second positioning mold 312 to ensure the stability of the mask position. The third clamping drive 3231 can be a finger cylinder, and its two driving ends can drive the clamping plate 3232 to move so that the clamping plate 3232 can clamp the mask. Since the mask is clamped and the part where the elbow joint is installed is a cylindrical protrusion, the arc-shaped clamping groove on the clamping plate 3232 can clamp the mask more safely and reliably.

[0052] The utility model relates to an automatic assembly machine for a spray mask joint. The working principle and process are as follows: the semi-finished mask is loaded onto the first rotating indexing plate 11, the first rotating plate 111 drives the first positioning mold 112 to rotate to a preset position, and then the mask conveying mechanism 12 conveys the semi-finished mask to the second positioning mold 312 of the second rotating indexing plate 31, wherein a group of tightening components 322 press the mask to perform the first positioning of the mask, and the second rotating plate 311 rotates so that the semi-finished mask is opposite to the joint feeding device 2. At this time, the other group of tightening components 322 presses the mask and the clamping component 323 above the mask holds the mask tightly, thereby realizing the secondary positioning of the mask to wait for the assembly of the elbow joint.

[0053] The elbow joint is loaded through the vibration disk assembly 211, so that the elbow joint is quickly sent to the straight vibration conveying assembly 212. The elbow joint can be arranged during the vibration process to ensure its uniform distribution. The elbow joint vibrates and moves on the straight vibration plate 2121. When the elbow joint is conveyed to the position of the reversing mechanism 22, the reversing mechanism 22 rotates the elbow joint 90°, and then the joint conveying mechanism 23 conveys the elbow joint to the alcohol dipping mechanism 4. After dipping in alcohol, the elbow joint is assembled with the semi-finished mask on the second dividing plate. The finished mask with the assembled joint is conveyed to the finished product conveying line 52 by the finished product conveying mechanism 51, and a single assembly is completed.
