The first side plate 221 is parallel to the first support plate 20, and a gap for accommodating a tray is formed between the opposite side surfaces of the first side plate 221 and the first support plate 20. The two groups of first guide wheel assemblies 222 are distributed at intervals in front and back, and a first tray accommodating space is formed between the two groups of first guide wheel assemblies 222, the first side plate 221 and the first support plate 20. The top surfaces of the first side plate 221 and the first support plate 20 are flush and parallel to the top surface of the top plate 113, which facilitates the taking and placing of the tray. The first guide wheel assembly 222 is composed of a connecting shaft 2220 and a first guide wheel 2221, and its specific structural layout is shown in Figure 4

[0033] ​In this embodiment, the double-layer magazine assembly 3 further comprises a second support plate 30, the bottom of the second support plate 30 is provided with a second fixing plate 31, the bottom of the second fixing plate 31 is also provided with a plurality of locking pins 51 and positioning pins 52 distributed at intervals, and the second fixing plate 31 is stably installed on the top plate 113 through the locking pins 51 and the positioning pins 52 thereon. The top of the second support plate 30 is provided with a continuous first step 301 and a second step 302, and the first step 301 is higher than the second step 302. The second tray support is arranged at the first step 301, and the third tray support is arranged at the second step 302, so that the position height of the second tray support is higher than that of the third tray support, and the second tray support and the third tray support are distributed in a staggered manner, which is helpful to adapt to different flyers for taking material work and avoid taking material restrictions caused by the height difference inside the fly base. When taking material, the material belt of the tray stored in the second tray support serves as an upper layer material belt, and the material belt of the tray stored in the third tray support serves as a lower layer material belt, so as to facilitate the upward and downward conveying of the material belts in different trays.

[0034] Specifically, the second tray support comprises a second side plate 321, a third side plate 322 and two groups of second guide roller assemblies 323, the second side plate 321 is arranged at the first step 301, and the third side plate 322 is connected to one side of the second side plate 321 through the two groups of second guide roller assemblies 323; the third side plate 322 is parallel to the second side plate 321, and a gap for accommodating the tray is also formed between the opposite sides of the third side plate 322 and the second side plate 321. The two groups of second guide roller assemblies 323 are distributed at intervals in front and back, and a second tray accommodating space is formed between the two groups of second guide roller assemblies 323 and the second side plate 321 and the third side plate 322. Among them, the tread surfaces of the first step 301 and the second step 302 are parallel to the top surface of the top plate 113, and the top surfaces of the third side plate 322 and the second side plate 321 are flush and parallel to the top surface of the top plate 113, which facilitates the taking and placing of the tray. The structure and layout of the second guide roller assembly 323 are the same as those of the first guide roller assembly 222, which are specifically shown in Figure 5

[0035] In this embodiment, the first tray accommodating space is larger than the second tray accommodating space, and the size of the tray that can be stored in the first tray accommodating space is larger than the size of the tray that can be stored in the second tray accommodating space. For example, the size of the tray that can be stored in the first tray accommodating space is 13 inches, and the size of the tray that can be stored in the second tray accommodating space is 7 inches.

[0036] ​It should be noted that in the embodiment, the structure layout of the third tray support and the size of the tray accommodating space thereof are the same as those of the second tray support, i.e., the size of the tray that can be stored by the third tray support is also 7 inches. In other embodiments, the third tray support can also adopt other suitable structure layouts, and the size of the tray accommodating space thereof can be the same as or different from that of the second tray accommodating space, so as to meet the storage and feeding belt conveying of the corresponding tray.

[0037] In the embodiment, the second support plate 30 is provided with two groups of third guide roller assemblies 33 on one side thereof, and the two groups of third guide roller assemblies 33 are distributed obliquely upward in the direction away from the third tray support. One group of third guide roller assemblies 33 is located on the side of the second tray support away from the third tray support and close to the top of the second support plate 30. When the feeder is located on the side of the second tray support away from the third tray support, the third tray support is far away from the feeder, and the two groups of third guide roller assemblies 33 can be used to convey the feeding belt of the tray stored in the third tray support, so as to ensure the stability of the conveying. The third guide roller assembly 33 is composed of a feeding belt guide plate 330 and two second guide rollers 331, and the two second guide rollers 331 are located on the two sides of the feeding belt guide plate 330. A gap for the feeding belt to pass through is formed between the feeding belt guide plate 330 and the two second guide rollers 331, and the specific structure layout is shown in the figure.

[0038] It should be noted that the guidance of the guide rollers in the two groups of third guide roller assemblies 33 can be designed according to the actual application of the feeding belt, and the drawings are only examples.

[0039] In the embodiment, the top surface of the top plate 113 is an inclined surface, and the inclination angle of the inclined surface is not less than 30°. Specifically, the inclination angle of the inclined surface is 35°, so as to facilitate the taking and placing of the tray by the tray taking and placing robot. For example, the upper end of the connecting plate 112 is designed to be an inclined surface, and when the top plate 113 is installed on the connecting plate 112, the top plate 113 also corresponds to be inclined, and the top surface of the top plate 113 is also inclined. At the same time, the first support plate 20 and the second support plate 30 on the top plate 113 are also inclined synchronously. When selecting the inclination direction, the side provided with the third tray support can be inclined downward.

[0040] In specific implementation and application, the trolley compatible with multiple sizes of trays is usually fixed below an SMT chip mounter (not shown in the figure), and the conveying direction of the feeding belt of each multiple size of tray is as shown in the figure. Figure 6The tape of the tray in the first tray support (13 inch tray) is directly connected to the feeder (not shown in the figure), the tape of the tray in the second tray support (7 inch tray) is directly connected to the feeder (not shown in the figure), and the tape of the tray in the third tray support (7 inch tray) is connected to the feeder (not shown in the figure) after passing through the middle of the two groups of tape guide plates and guide wheels, which is suitable for different SMT chip mounters. Through cooperation with a suitable SMT tray automatic taking and placing mechanism, high-efficiency automatic taking and placing of the material can also be realized. The SMT tray automatic taking and placing mechanism is, for example, a taking and placing mechanical arm commonly used in the prior art.
