Preferably, a plurality of interception plates 26 capable of restricting the mounting substrate 4 from moving relative to the conveyor 22 in the moving direction of the conveyor 22 are provided at intervals on the conveyor 22. The intercept plate 26 can be used to limit the relative movement of the mounted substrate 4 that may occur on the conveyor belt 22.

As shown in fig. 3, the limit clamping unit 24 includes a mounting plate 241, a positioning rod 242, a limit stop 243, a clamping plate 244, and an elastic member 245. Specifically, two mounting plates 241 are fixedly connected to the upper surface of the support frame 21, and the plane of the plate body where the mounting plates 241 are located is parallel to the translation plane constructed by the conveyor belt 22. It is further preferable that two mounting plates 241 disposed opposite to both sides of the conveyor belt 22 support the positioning rods 242 near the surface of the conveyor belt 22.

And a portion of the rod body of the positioning rod 242 remote from the mounting plate 241 is suspended above the conveyor belt 22. Preferably, a limit stop 243 is also connected to the end of the positioning rod 242 remote from the mounting plate 241. The limit stop 243 is suspended above the conveyor belt 22, and the limit stop 243 plate surface is parallel to the conveyor belt 22. Further preferably, the surface of the limit baffle 243 facing the conveyor belt 22 is also movably connected with a clamping plate 244, that is, the surface of the limit baffle 243 facing the conveyor belt 22 is also movably connected with a clamping plate 244 capable of clamping and limiting the mounting substrate 4 following the movement of the conveyor belt in a direction perpendicular to the movement direction of the conveyor belt 22 in the mounting plane defined by the conveyor belt 22. Further preferably, the clamping plate 244 can translate along the axial direction of the positioning rod 242 relative to the limit baffle 243, and the surface of the limit baffle 243 near the clamping plate 244 is provided with a first sliding groove 246 which can be matched with a sliding block 247 installed on the surface of the clamping plate 244, so that the sliding block 247 can drive the clamping plate 244 to reciprocate in the first sliding groove 246.

When the mounting substrate 4 following the movement of the conveyor belt 22 moves between the two holding plates 244, the holding plates 244 receive the elastic force transmitted by the slider 247 to define the distance between the mounting substrate 4 and the both side edges of the conveyor belt 22. Preferably, the clamping plates 244 may be fan-shaped plates, and the arc-shaped sides of the clamping plates 244 are in contact with the mounting substrate 4, so that during the directional movement of the mounting substrate 4, the mounting substrate 4 can push the clamping plates 244 to gradually translate out of the space right above the conveyor belt 22, but the clamping plates 244 are blocked by the elastic members 245 to resist the acting force exerted by the mounting substrate 4 on the clamping plates, so that a balancing device with mutually offset acting force is formed between the two oppositely arranged clamping plates 244 and the mounting substrate 4, and as the elastic members 245 outside the two clamping plates 244 are of the same model, the moving distance of the two clamping plates 244 is equal, that is, the plate bodies of the two clamping plates 244 in the space region right above the conveyor belt 22 are equal in size, so that the distance from the mounting substrate 44 between the two clamping plates 244 to the two side edges of the conveyor belt 22 is equal, and the clamping plates 244 are ensured to be in the central line region of the conveyor belt 22 in the length direction. The adjustable structure of the clamping plates 244 enables the width defined by the two opposite clamping plates 244 to be changed according to the actual width of the mounting substrate 44, so that the same limiting clamping unit 24 can be used for clamping limiting and relative position adjustment of the mounting substrates 44 with different sizes, and the device can be suitable for mounting processing of the mounting substrates 44 with various sizes, and the application range of the device is improved. The combined restriction of the holding plate 244 and the interception plate 26 can effectively and accurately restrict the position of the mounting substrate 4, so that the mounting substrate 4 can be parked at a fixed point on the mounting station corresponding to the mounting assembly 3.

Preferably, the connecting piece 343 is further connected with a telescopic adjusting piece 346, and the telescopic adjusting piece 346 can adjust the number of concentric rings in the working plane, so that the sucking operation of the components can be performed by the plurality of sucking discs 344 on at least one ring.

In particular, the connecting member 343 is controlled by the adjusting member 346 to change the maximum area defined by the concentric circles, so that the connecting member 343 can define different numbers of suction cups 344 for working, the suction surface defined by the suction cups 344 can be adjusted, and the mounting head 34 can perform suction operation on components with different sizes.
