[0002] Fully automatic chip mounters are used to place components automatically at high speed and high precision. They are the most critical and complex equipment in the entire SMT production. Chip mounters are the main equipment in the SMT production line. Chip mounters have developed from early low-speed mechanical chip mounters to high-speed optical centering chip mounters, and have developed towards multi-functional, flexible connection modularization.

[0003] However, the transmission mechanism of the existing placement machine equipment is an ultra-thin belt transmission system mounted on a guide rail.

Obviously, the described embodiments are only part of the embodiments 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 creative work are within the scope of protection of the utility model.

[0036] Depend on Figure 1 to Figure 2 A steel sheet mounting device is provided, comprising a machine body 1 and a conveying mechanism 2 installed on one side of the machine body 1 .

[0037] The conveying mechanism 2 includes a conveying guide rail assembly 21 , a positioning assembly 22 , a transmission assembly 23 , and an adjustment and lifting assembly 24 .

[0038] The conveying guide rail assembly 21 is installed on one side of the machine body 1, and the steel strip is transported on the top of the conveying guide rail assembly 21; the positioning assembly 22 is installed on one side of the machine body 1 to limit the steel strip; the transmission assembly 23 is installed on one side of the conveying guide rail assembly 21 to move the steel strip; the adjustment and lifting assembly 24 is installed on one side of the transmission assembly 23, pressed above the steel strip, and cooperated with the conveying guide rail assembly 21 to drive the steel strip to move.

[0039] The beneficial effects obtained by the conveying mechanism 2 including the conveying guide rail assembly 21, the positioning assembly 22, the transmission assembly 23, and the adjusting and lifting assembly 24 are as follows: the steel strip is laid flat on the top of the conveying mechanism 2 including the conveying guide rail assembly 21, and the positioning assembly 22 limits the steel strip to ensure that the steel strip does not tilt during transportation; the steel strip is placed between the transmission assembly 23 and the adjusting and lifting assembly 24, and the transmission assembly 23 can rotate. The transmission assembly 23 drives the steel strip to move and transport during rotation, thereby increasing the efficiency of the steel strip transportation, ensuring that the steel strip will not get stuck or broken during the transportation process, and greatly improving the output.

[0040] Depend on Figure 1 to Figure 2 It is shown that the conveying guide rail assembly 21 includes a support plate 211 , a front conveying plate 212 , two roller support plates 216 , a roller 214 , a rear conveying plate 215 and two sensors 213 .

[0041] The support plate 211 is installed on one side of the machine body 1, the front conveying plate 212 is installed on one side of the support plate 211, and the rear conveying plate 215 is installed on the side of the transmission component 23 away from the support plate 211. The side of the front conveying plate 212 away from the support plate 211 is inclined downward, the positioning component 22 and the transmission component 23 are located between the front conveying plate 212 and the rear conveying plate 215, and the side of the rear conveying plate 215 away from the transmission component 23 is inclined downward; the steel plate is laid flat on the surface of the front conveying plate 212, and the steel sheet belt on the side of the front conveying plate 212 away from the support plate 211 is in a relaxed state.

[0042] The two sensors 213 are respectively installed at the middle of the front conveying plate 212 and the rear conveying plate 215 . The sensors 213 are used to detect the steel strips on the front conveying plate 212 and the rear conveying plate 215 .

[0043] The two roller support plates 216 are installed at the front and rear ends of one side of the support plate 211 by screws, and the roller 214 is rotatably installed between the two roller support plates 216. The two roller support plates 216 can adjust the up and down heights on one side of the support plate 211. The steel sheet belt reaches the roller 214 from the front conveying plate 212, and is then conveyed to the rear conveying plate 215 after passing through the positioning component 22 and the transmission component 23.

[0044] The purpose of the steel strip entering the front section of the roller 214 is to ensure that the steel strip has a sufficient R angle so as not to break. The sensor 213 detects whether the steel strip enters the roller 214.

Four first limit plates 223 are provided, and the four first limit plates 223 are symmetrically installed on the front and rear sides of the top of the middle conveying plate 221 by bolts. The first limit plate 223 can be adjusted in position at the top of the middle conveying plate 221 by bolts, thereby adjusting the distance between the two symmetrical first limit plates 223, and is used for limiting and clamping steel strips of different widths.

[0047] Two second limit plates 224 are provided, and the two second limit plates 224 are symmetrically installed on the top of the four first limit plates 223 by bolts.

The limit groove 222 is opened on one side of the first limit plate 223 and the second limit plate 224. The two sides of the steel strip are inserted into the limit groove 222. The two sides of the steel strip do not contact the inner wall of the limit groove 222, and ensure that the steel sheet does not generate friction with the positioning plate 225 to protect the surface finish. Chamfers are opened at both ends of the limit groove 222 to facilitate the entry of the steel strip.

[0048] The second cylinder 226 is installed at the bottom of the middle conveying plate 221, and the output end of the second cylinder 226 is connected to the positioning plate 225. When the steel strip is mounted, the second cylinder 226 drives the positioning plate 225 to rise and fall, and the positioning plate 225 rises to support the bottom of the steel strip to avoid the bottom of the steel strip being suspended when the steel strip is mounted.

[0049] Depend on Figures 4 to 5 It is shown that the conveying assembly 23 includes a supporting frame 231 , a first driving rod 232 , two first conveying rollers 233 , a driving member 236 , a second driving rod 234 and two second conveying rollers 235 .

The driving member 236 is installed on one side of the support frame 231. The driving member 236 is a motor, and the output end of the motor is connected with the first driving rod 232. The motor drives the first driving rod 232 to drive the first conveying roller 233 to rotate.

[0051] The second driving rod 234 is installed on one side of the adjusting lifting component 24, and the two second conveying rollers 235 are installed on both sides of the second driving rod 234. The two second conveying rollers 235 and the two first conveying rollers 233 are symmetrically arranged up and down. The steel strip is laid between the first conveying roller 233 and the second conveying roller 235. The first conveying roller 233 and the second conveying roller 235 are clamped, and the second conveying roller 235 is pressed on the upper surface of the steel strip. The first conveying roller 233 rotates to drive the steel strip to be conveyed.

[0052] The pressing of the second conveying roller 235 increases the friction between the first conveying roller 233 and the steel strip, which is used to ensure sufficient friction during conveying and to ensure that the steel strip does not get stuck during conveying.

[0053] Fixed plates 239 are installed on both sides of the support frame 231, and the two sides of the fixed plate 239 are respectively abutted against one side of the middle conveying plate 221 and the rear conveying plate 215.

[0056] The two springs 246 are respectively installed on the top of the two connecting arm plates 242 close to the connecting rod 243, and the other ends of the two springs 246 are installed on the inner top wall of the supporting frame 231. The first cylinder 247 is installed on the top of the supporting frame 231. The output end of the first cylinder 247 is connected with the connecting rod 243. The first cylinder 247 drives the connecting rod 243 to rise and fall, and the connecting rod 243 drives the connecting arm plate 242 to rise and fall. When the connecting arm plate 242 is limited by the rotating rod 241, one end of the connecting arm plate 242 follows the connecting rod 243 to rise, and the other end rotates around the axis of the rotating rod 241. During the movement of the connecting arm plate 242, the second driving rod 234 is driven to rise, and the second driving rod 234 drives the second conveying roller 235 away from the first conveying roller 233.

[0057] The positioning rod 244 is installed inside the supporting frame 231, and the two positioning blocks 245 are installed on both sides of the positioning rod 244.

The bottom of the connecting arm plate 242 abuts against the top of the positioning block 245. The handle 248 is turned to rotate the positioning rod 244 and the positioning block 245. The two positioning blocks 245 push the connecting arm plate 242 up during the process, and the second driving rod 234 installed on the connecting arm plate 242 rises together, thereby driving the second conveying roller 235 to rise away from the first conveying roller 233.
