DETAILED DESCRIPTION

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1, such as Figures 1-4 The present invention provides the following technical solution to address the problem of inconvenient replacement of parts in assembly machines, which affects user experience: A locking mechanism is disclosed, comprising a main body 1, a telescopic cylinder 2 installed inside the main body 1, a suction plate 3 connected to the bottom of the telescopic cylinder 2, and a conveying assembly 4 connected through the inner side of the main body 1. Three external blocks 201 are fixed to the bottom surface of the telescopic cylinder 2. Telescopic grooves 202 are formed on the sides of the external blocks 201 away from the center. A rotating wheel 204 is rotatably connected inside the central external block 201. A telescopic block 203 slides through the telescopic groove 202. A locking mechanism is provided inside the external blocks 201 to improve the replacement efficiency of the conveying assembly 4. The engaging mechanism includes a telescopic block 203, which slides through the telescopic groove 202. A spring connects the telescopic block 203 and the telescopic groove 202. A pull rope 205 is connected to the side of the telescopic block 203. The pull rope 205 moves through the telescopic groove 202 and the central outer block 201. The end of the pull rope 205 away from the telescopic block 203 is wrapped around the surface of the rotating wheel 204. A rotating rod 206 is fixed on the upper surface of the rotating wheel 204. The rotating rod 206 rotates through the central outer block 201. A fixing block 207 is fixed on the upper surface of the suction plate 3. An engaging groove 208 is opened on the inner side of the fixing block 207. The engaging groove 208 and the telescopic block 203 are engaged.

[0031] When the assembly machine is in use, the telescopic cylinder 2 can move inside the machine body 1. When the telescopic cylinder 2 moves, it can drive the suction plate 3 to move. When the suction plate 3 moves, it can move the processed parts placed inside the machine body 1 to the upper surface of the fixture of the conveying component 4. The conveying component 4 then conveys the placed fixture and products to the next process. The suction plate 3 may be damaged after long-term use. Rotating the rotating rod 206 can drive the rotating wheel 204 to rotate. When the rotating wheel 204 rotates, it can rotate inside the central outer block 201. When the rotating wheel 204 rotates, it can wind the pull rope 205 on the surface. When the pull rope 205 is generated, it can pull the telescopic cylinder 205 to move the machine body 1. When the telescopic block 203 moves, it can slide through the telescopic groove 202 and the engaging groove 208. When the telescopic block 203 slides, it can compress the spring. After the telescopic block 203 is squeezed out of the engaging groove 208, it pulls down the suction plate 3. When the suction plate 3 is pulled down, it can drive the fixed block 207 to move. When the fixed block 207 moves, it can slide through the outer connecting block 201 and the telescopic cylinder 2. When the fixed block 207 slides out of the side of the outer connecting block 201, it can be separated from the telescopic cylinder 2. At this time, the telescopic cylinder 2 and the suction plate 3 are separated and disassembled. After the suction plate 3 is disassembled, it can be quickly replaced with a new one, which improves the efficiency of the assembly machine.

[0032] Example 2, as follows Figure 5 and 6 The present invention provides the following technical solution: In order to solve the problem that it is inconvenient for the assembly machine to clean the dust on the surface of the processed parts, a dust blowing mechanism is disclosed: a fixed plate 301 is symmetrically fixed on both sides of the suction plate 3, and a dust blowing mechanism to improve the assembly accuracy of the assembly machine is provided at the bottom of the fixed plate 301. The dust blowing mechanism includes an air bag 302, which is connected to the bottom of the fixed plate 301. A jet block 303 is symmetrically installed at the bottom of the suction plate 3. A connecting pipe 304 is connected between the nozzle of the jet block 303 and the air bag 302. A one-way valve 305 is connected to the side of the air bag 302 away from the connecting pipe 304. A squeezing block 306 is symmetrically fixed inside the machine body 1, and the squeezing block 306 is located directly below the fixed plate 301.

[0033] When the assembly machine operates on the workpiece, the telescopic cylinder 2 will drive the suction plate 3 to move directly above the workpiece. Then, the output end of the telescopic cylinder 2 will drive the suction plate 3 to move downward. When the suction plate 3 moves downward, it can drive the airbag 302 to the inclined surface of the extrusion block 306 for extrusion. When the airbag 302 is extruded, it can deform and expel the internal gas. When the gas is extruded from the airbag 302, it can be transported to the inside of the jet block 303 through the connecting pipe 304. After the jet block 303 increases the pressure of the gas and extrudes it, it can achieve the blowing effect. When blowing, it can clean the dust that may be present on the surface of the workpiece. When the dust is cleaned, the suction plate 3 will not slip on the workpiece due to the dust, preventing the workpiece from tilting when placed on the surface of the conveying component 4. This indirectly improves the accuracy of the assembly machine during processing. In addition, the one-way valve 305 on the side of the airbag 302 can quickly absorb the external gas when the extrusion block 306 separates from the airbag 302, so that the airbag 302 can be replenished with gas in a short time.

[0034] Example 3, as follows Figure 5 and Figure 6 The present invention provides the following technical solution: In order to solve the problem that the jet block 303 of the assembly machine is inconvenient to adjust the angle and affects the dust blowing effect, a rotating mechanism is disclosed: The bottom of the suction plate 3 is provided with a rotating mechanism to improve the dust blowing effect of the jet block 303. The rotating mechanism includes a rotating block 308, which is symmetrically fixed on both sides of the jet block 303. The jet block 303 rotates inside the rotating groove 307 through the rotating block 308. A friction plate is connected to the surface of the rotating block 308. The rotating groove 307 is symmetrically opened at the bottom of the suction plate 3.

[0035] Before use, the jet block 303 of the assembly machine can be rotated. When the jet block 303 rotates, it can drive the rotating block 308 to rotate. When the rotating block 308 rotates, it can rotate through the rotating groove 307. When the rotating block 308 rotates, the friction plate on its surface can squeeze the side wall of the rotating groove 307. The friction plate can generate a large friction force. The friction force can position the jet block 303 at the swing angle, so that the jet block 303 can be adjusted at will, thereby improving the dust removal effect of the jet block 303 and improving the ease of use of the assembly machine.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
