[0036] Please refer to Figure 1 The present embodiment provides a tray feeding device 100, comprising a frame 110, and an operating platform 112 disposed on the frame 110, the operating platform 112 comprising a material taking area and a material discharging area disposed relatively, the material taking area comprising a first upper bin 120, a first working area 130, a first transfer area 140 and a first lower bin 150, the first upper bin 120 is provided with a first tray assembly 122 (such as Figure 2 As shown), the first tray assembly 122 is used to separate the stacked trays 105 of the first upper bin 120 (as shown in FIG. Fig. 9 A first loading assembly 124 (as shown) is provided between the first loading bin 120 and the first working area 130. Figure 3 The first loading assembly 124 is used to transport the separated material tray 105 from the first loading bin 120 to the first working area 130. A first dial assembly 136 (as shown in FIG. 1 ) is provided between the first working area 130 and the first transfer area 140. Figure 8As shown), the first dial assembly 136 is used to move the material tray 105 after taking the material to the first transfer area 140, and a first material discharge assembly 142 is provided between the first transfer area 140 and the first material discharge bin 150. The first material discharge assembly 142 is used to transport the material tray 105 after taking the material to the first material discharge bin 150. The first material discharge bin 150 is provided with a first material discharge lifting assembly 152 (as shown Figure 6 As shown), the first material unloading lifting assembly 152 is used to stack the material trays 105 transported to the first material unloading bin 150, and the material unloading area is used to unload the stacked material trays 105 after taking the materials.

[0037] It should be noted that, whenever the material on the tray 105 of the first working area 130 is taken, the first tray separation component 122 separates one of the stacked trays 105 in the first upper bin 120, and the first upper bin 124 moves the separated tray 105 to the first working area 130 for taking the material. The tray 105 after taking the material is moved to the first lower bin 150 by the first unloading component 142, and the trays 105 moved to the first lower bin 150 are stacked by the first unloading lifting component 152, and the stacked trays 105 after taking the material are placed in the discharge area for discharge, thereby completing the required working process in a cycle.

[0038] The tray feeding device 100 provided in the embodiment of the present invention can separate the trays 105 stacked in the first upper bin 120 through the first tray separation assembly 122 arranged in the first upper bin 120, so as to facilitate the transportation to the first working area 130. The separated trays 105 can be transported from the first upper bin 120 to the first working area 130 through the first loading assembly 124 arranged between the first upper bin 120 and the first working area 130, so as to facilitate the material picking operation. The trays 105 after picking can be moved to the first transfer area 140 through the first dial assembly 136 arranged between the first working area 130 and the first transfer area 140. The trays 105 after picking can be transported to the first lower bin 150 through the first unloading assembly 142 arranged between the first transfer area 140 and the first lower bin 150. The first material unloading lifting assembly 152 provided in the first material unloading bin 150 can stack the material trays 105 transported to the first material unloading bin 150. The stacked material trays 105 after the material unloading operation is completed in the material unloading area can be placed in the material unloading area for unloading operation. The unloading process does not require manual intervention, which can improve the degree of automation during loading and unloading, thereby improving work efficiency.

[0039] like Figure 1 As shown, the discharge area includes a second upper bin 160, a second transfer area 170, a second working area 180 and a second lower bin 190. The second upper bin 160 is provided with a second tray assembly 162 (such as Figure 2The second tray-dividing assembly 162 is used to divide the trays 105 stacked in the second upper bin 160 into trays, and a second loading assembly 164 (as shown in FIG. 1 ) is provided between the second upper bin 160 and the second transfer area 170. Figure 4 The second loading assembly 164 is used to transport the separated material tray 105 from the second loading bin 160 to the second transfer area 170. A second dial assembly 172 (as shown in FIG. 1 ) is provided between the second transfer area 170 and the second working area 180. Figure 8 The second dial assembly 172 is used to move the material tray 105 to be discharged to the second working area 180, and a second material discharge assembly 182 (as shown in FIG. 1 ) is provided between the second working area 180 and the second material discharge bin 190. Figure 5 As shown), the second unloading assembly 182 is used to transport the material tray 105 after discharge to the second unloading bin 190, and the second unloading assembly 182 also includes a second unloading lifting assembly 1825, and the second unloading lifting assembly 1825 is used to stack the material trays 105 transported to the second unloading bin 190.

[0040] Specifically, the stacked trays 105 in the second upper bin 160 are separated into one under the action of the second tray separation assembly 162, and the separated tray 105 is transported to the second transfer area 170 by the second upper bin assembly 164. The second dial assembly 172 then moves the trays 105 in the second transfer area 170 to the second working area 180 for unloading, and the trays 105 after unloading are transported to the second lower bin 190 by the second unloading assembly 182, and then the trays 105 transported to the second lower bin 190 are stacked by the second unloading lifting assembly 1825, and the stacked trays 105 after unloading are placed in the material picking area for material picking, thereby completing the required work process in a cycle. The process of picking and unloading does not require manual intervention, which can improve the degree of automation during loading and unloading, thereby improving work efficiency. Through the tray feeding device 100 of this embodiment, machines can replace manual labor, reducing the labor intensity and production costs of workers, which is beneficial to improving the efficiency of the enterprise.

[0041] like Figure 2 As shown, the first sub-disk assembly 122 and the second sub-disk assembly 162 both include a slide rail 1221 and an extrusion block 1222 fixed on the operating platform 112, and a slide cylinder 1224 slidably connected to the slide rail 1221 through a fixed seat 1223, the slide cylinder 1224 includes a cylinder body 1225 and a slide 1226 that are connected to each other, and sub-disk buckles 1227 are respectively provided on opposite sides of the slide 1226, a guide slope 12222 is provided on the extrusion block 1222, and a cam follower 1228 that abuts against the guide slope 12222 is correspondingly provided on the slide 1226, a spring seat 1229 is provided on the slide rail 1221, and an elastic member is provided between the spring seat 1229 and the fixed seat 1223.

[0042] Specifically, through the guide slope 12222 provided on the extrusion block 1222 and the cam follower 1228 provided on the slide 1226 and correspondingly abutting against the guide slope 12222, when the cylinder body 1225 drives the slide 1226 to slide out, the fixing seat 1223 slides along the slide rail 1221 under the action of the guide slope 12222. At this time, the tray-separating buckle 1227 has a tendency to lift up and approach the tray 105, so that the tray-separating buckle 1227 lifts up all the trays 105 above the second one, and retains the tray 105 at the bottom to be transported to the first working area 130.

[0043] When the slide 1226 is retracted, in order to ensure that the fixed seat 1223 returns to the initial position, an elastic member is set between the spring seat 1229 and the fixed seat 1223. For example, when a compression spring is set between the spring seat 1229 and the fixed seat 1223, the compression spring is located in the direction in which the fixed seat 1223 slides when the slide 1226 is lifted. At this time, when the slide 1226 is lifted, the compression spring is compressed by force and accumulates elastic potential energy. When the slide 1226 is retracted, the compression spring releases the elastic potential energy, so that the fixed seat 1223 returns to its original position. Similarly, a tension spring can also be set between the spring seat 1229 and the fixed seat 1223. The tension spring is located in the direction away from the sliding direction of the fixed seat 1223 when the slide 1226 is lifted. The specific force analysis is the same as that of the compression spring, which will not be repeated here. Through the above form, the first sub-disk assembly 122 and the second sub-disk assembly 162 can continue to work without manual intervention, which is conducive to improving work efficiency.

[0044] like Figure 3 As shown, the first loading assembly 124 includes a first slide rail module 1242, the first slide rail module 1242 includes a first lead screw 1243 and a first sliding block 1244 connected to the first lead screw 1243, and the first sliding block 1244 is provided with a first transport pallet 1247 connected to the first sliding block 1244 through a first lifting cylinder 1245.

[0045] Specifically, the first sliding block 1244 reciprocates on the first lead screw 1243, driving the first transport tray 1247 to move between the first upper bin 120 and the first working area 130. After the first tray separation assembly 122 separates a tray 105, the first transport tray 1247 is lifted by the first lifting cylinder 1245, so as to avoid interference between the tray 105 and the operating platform 112 during the movement, which is conducive to improving the stability of the transport process.

[0046] like Figure 4As shown, the first unloading assembly 142 and the second loading assembly 164 both include a first rodless cylinder 1422 and a first shifting block 1424 disposed on the first rodless cylinder 1422 , and the first shifting block 1424 can reciprocate along the first rodless cylinder 1422 .

[0047] Specifically, in this embodiment, the first rodless cylinder 1422 can adopt a magnetically coupled rodless cylinder. By installing a set of high-strength permanent magnetic rings on the piston, the magnetic lines of force pass through the thin-walled cylinder and act on another set of magnetic rings in the first shift block 1424. Since the two sets of magnetic rings have opposite magnetic properties, they have a strong mutual attraction. When the piston is pushed by the air pressure in the cylinder, the piston moves. At the same time as the piston moves, the magnetic rings in the external first shift block 1424 are affected by the magnetic lines of force of the magnetic rings on the piston and move synchronously. In the process of transporting the tray 105 from the first transfer area 140 to the first lower bin 150 or from the second upper bin 160 to the second transfer area 170, no material is placed on the tray 105. The use of the first rodless cylinder 1422 can save costs while realizing the transfer of the tray 105, which is conducive to improving economic benefits.

[0048] like Figure 6 and Figure 7 As shown, the first material unloading lifting assembly 152 includes a telescopic cylinder 1522 and a bracket 1524 connected to the telescopic cylinder 1522. The first material unloading bin 150 and the second material unloading bin 190 are both provided with a plurality of swing clips 154. The swing clips 154 include a fixed seat 1542 and a first pin shaft 1543 and a second pin shaft 1545 arranged on the fixed seat 1542. The first pin shaft 1543 is provided with a clip 1547, and the clip 1547 has a first state of expansion and a second state of supporting the material tray 105.

[0049] Specifically, after the material tray 105 is transferred to the first material storage bin 150, the first material loading and unloading lifting assembly 152 lifts the material tray 105 through the bracket 1524. During the lifting process of the material tray 105, the buckle 1547 rotates along the first pin shaft 1543 until the buckle 1547 is fully unfolded, so that the material tray 105 is located above the buckle 1547. After the material tray 105 is located above the buckle 1547, the buckle 1547 is no longer affected by the force of the material tray 105. The buckle 1547 restores its original state under its own action, that is, it abuts against the second pin shaft 1545. At this time, the telescopic cylinder 1522 retracts, the material tray 105 falls back, and abuts against the buckle 1547, realizing the second state of supporting the material tray 105. Through multiple lifting and retraction, the purpose of stacking the material trays 105 is achieved.

[0050] It should be noted that the present embodiment does not impose any specific restrictions on the distribution position and number of the swing buckles 154, as long as they can provide stable support. For example, the swing buckles 154 can be arranged on opposite sides of the first transfer area 140 and the transmission channel of the first lower bin 150, and two swing buckles 154 are arranged, which can provide support to ensure the stacking of the material trays 105 without affecting the transmission of the material trays 105.

[0051] like Figure 5 As shown, the second material unloading component 182 includes a second slide rail module 1822, the second slide rail module 1822 includes a second lead screw 1823 and a second sliding block 1824 connected to the second lead screw 1823, the second sliding block 1824 is provided with a second transport pallet 1828 connected to the second sliding block 1824 via a second material unloading lifting component 1825, the second material unloading lifting component 1825 includes a second lifting cylinder 1826 and a third lifting cylinder 1827 which are transmission-connected, wherein the second lifting cylinder 1826 is connected to the second sliding block 1824, and the third lifting cylinder 1827 is connected to the second transport pallet 1828.

[0052] Specifically, in order to ensure the stable transmission of the material tray 105 after the material is discharged, the second lifting cylinder 1826 (or the third lifting cylinder 1827) can be lifted to separate the material tray 105 from the operating platform 112 during the process of transferring the material tray 105 from the second working area 180 to the second lower material bin 190, so as to avoid interference during the transfer process. After the material tray 105 is transferred to the second lower material bin 190, the third lifting cylinder 1827 (or the second lifting cylinder 1826) is lifted to position the material tray 105 above the buckle 1547, and the material tray 105 is abutted against the buckle 1547 when it falls back, so as to realize the stacking support of the material tray 105.

[0053] like Figure 8 As shown, the first dial assembly 136 and the second dial assembly 172 both include a second rodless cylinder 1362 and a second dial block 1364 arranged on the second rodless cylinder 1362. The second dial block 1364 can reciprocate along the second rodless cylinder 1362. The second dial block 1364 is provided with a dial rod 1366 for moving the material tray 105.

[0054] Specifically, during the process of transferring the material tray 105 from the first working area 130 to the first transfer area 140 or from the second transfer area 170 to the second working area 180, no material is placed on the material tray 105. The use of the second rodless cylinder 1362 can save costs while realizing the transfer of the material tray 105, which is conducive to improving economic benefits.

[0055] like Fig. 9 and Fig.10As shown, the material tray feeding device 100 also includes a pressure plate assembly 132 and a side guard assembly 134 arranged in the first working area 130 and the second working area 180. The pressure plate assembly 132 is used to support the opposite sides of the material tray 105. The pressure plate assembly 132 includes a pressure plate cylinder 1324 and a pressure plate 1326 connected to the pressure plate cylinder 1324.
