[0034] The present invention will be further described below in conjunction with the accompanying drawings and implementation modes.

[0035] Please refer to Figures 1 to 6 A lifting tray continuous feeding assembly for plastic back cover, with a frame 101 as a support base. On the top of the frame 101, a material discharging tray conveyor frame 102 and a material collecting tray conveyor frame 103 are arranged on both sides, respectively, and they are responsible for placing and collecting the material trays. The material discharging bin 104 and the material collecting bin 105 are respectively installed at one end of the top of the two conveyor frames for storing the material trays.

[0036] The top of the collecting tray conveyor frame 103 is symmetrically fixed with mounting seats 125, and the first right-angled trapezoidal blocks 126 are cleverly designed in these mounting seats to match the edge of the material tray 107. One end of these right-angled trapezoidal blocks is connected to the mounting seats through springs 127, so that they can move flexibly when under pressure and quickly reset after the pressure disappears. The collecting cylinder 143 is fixed on the collecting tray conveyor frame, and its output shaft is connected to the collecting tray 144, and the lifting and lowering of the collecting tray is driven by the expansion and contraction of the cylinder.

[0037] Feed tray 107 Figure 7 As shown, an outwardly protruding edge is provided at the top edge, and an array of accommodating grooves are provided on the top of the material tray 107 for accommodating plastic back covers, so as to facilitate large-scale automated assembly of plastic back covers.

[0038] In order to realize the smooth conveying of the material tray, the two side walls of the collecting tray conveying frame 103 are rotatably connected to the second driving pulley 137 and the second driven pulley 138, which are closely connected through the second belt 139. The two side walls of the unloading tray conveying frame 102 are fixed with the second conveying motor 140, and the output shaft of the motor is connected to one end of the second driving pulley to provide power for the rotation of the belt.

[0039] When the collecting cylinder 143 is started, it will drive the collecting tray 144 to rise, thereby lifting the trays on the second belt 139. As the trays rise, their edges will squeeze the first right-angled trapezoidal block 126, compressing the spring 127. Once the edge of the tray passes over the right-angled trapezoidal block, the collecting tray 144 will continue to rise, lifting all the trays in the collecting bin 105 by a certain distance. At this time, the right-angled trapezoidal block is reset under the action of the spring. When the collecting cylinder drives the collecting tray to descend, the edge of the tray at the bottom will be blocked by the right-angled trapezoidal block, thereby ensuring that the trays can be collected one by one.

[0040] On the top of the tray conveyor frame 102, the first connecting plates 128 are symmetrically fixed, and a horizontal cylinder 129 is installed on one side of these connecting plates. The output end of the horizontal cylinder is connected to the second connecting plate 130, and the top of the second connecting plate is fixed to the vertical cylinder 131. The output end of the vertical cylinder is connected to the second right-angle trapezoidal block 132 that matches the edge of the tray 107 for supporting and moving the tray.

[0041] The two side walls of the unloading tray conveyor frame 102 are also rotatably connected to the first driving pulley 133 and the first driven pulley 134, which are connected by the first belt 135. The first conveying motor 136 is fixed to the two side walls of the unloading tray conveyor frame to provide power for the first driving pulley. The unloading cylinder 141 is fixed to the unloading tray conveyor frame, and its output shaft is connected to the unloading tray 142 for lifting and lowering the tray.

[0042] During the discharge process, the second right-angled trapezoidal block 132 will support the edge of the bottom tray in the discharge bin 104. When it is necessary to discharge, the discharge cylinder 141 will drive the discharge tray 142 to rise, contact the bottom of the bottom tray and lift all the trays. Then, the horizontal cylinder 129 will drive the vertical cylinder 131 and the second right-angled trapezoidal block to move outward, so that the right-angled trapezoidal block is withdrawn from the edge of the tray. Next, the vertical cylinder 131 will drive the right-angled trapezoidal block to rise so that it is directly opposite the second-to-last tray at the bottom. Then, the horizontal cylinder drives the right-angled trapezoidal block to move again, so that it returns to the bottom of the tray edge. Finally, the discharge cylinder 141 drives the discharge tray to descend, so that the bottom tray moves to the first belt. Under the action of gravity, the remaining trays in the discharge bin will move downward and contact the second right-angled trapezoidal block. Then, the vertical cylinder drives the right-angled trapezoidal block to move downward to prepare for the next discharge.

[0043] In order to realize the automatic transfer of the material tray from the collecting bin to the discharging bin, a mounting plate 106 is installed on one side of the frame 101. The mounting plate is designed with a conveying assembly 108 and a U-shaped groove 109 for conveying the material tray. The conveying assembly includes a sleeve frame 110 slidably connected to the U-shaped groove and a driving device 111 for driving the sleeve frame to move.

[0044] The driving device is composed of a motor 119, a driving pinion 120, a driven large gear 122, a rotating shaft 121 and a swing rod 123. The motor is fixed to one side of the mounting plate, and its output shaft is connected to the driving pinion. The driving pinion meshes with the driven large gear, thereby driving the rotating shaft and the swing rod to rotate. A slideway 124 is designed on the swing rod, and one end of the strip portion 113 of the sleeve is arranged in the slideway, so that the sleeve can slide along the U-shaped groove.

[0045] The sleeve frame 110 is composed of an annular portion 112 and a strip portion 113. A slide groove 114 is symmetrically designed on the annular portion, and a right-angled trapezoidal magnet block 115 for supporting the edge of the material tray is slidably connected in the slide groove. A square magnet 116 and a strip magnet block 117 that match the right-angled trapezoidal magnet block are fixed to the collection tray conveyor frame and the discharge tray conveyor frame respectively.

[0046] When the material tray needs to be transferred from the material collection bin to the material discharge bin, the motor 119 will drive the driving pinion to rotate, and then drive the driven large gear, the rotating shaft and the rocker arm to rotate. This causes the sleeve to slide along the U-shaped groove. During the sliding process, the right-angled trapezoidal magnet block will contact the edge of the material tray and shrink along the chute. When the annular portion moves to the material tray facing the bottom layer, under the repulsive force of the square magnet, the right-angled trapezoidal magnet block will reset and face the bottom edge of the material tray facing the bottom layer. Then the annular portion will rise along the material collection bin and lift all the material trays together. Then it will move to the material discharge bin along the track of the U-shaped groove. When the annular portion moves to the position facing the bar magnet block, although there is an attractive force between the bar magnet block and the right-angled trapezoidal magnet block, because the right-angled trapezoidal magnet block contacts the bottom edge of the material tray at the bottom layer and the material tray has a large mass, the right-angled trapezoidal magnet block will move along the chute. When the bottom material tray in the annular portion contacts the top material tray in the material discharge bin, the friction between the right-angled trapezoidal magnet block and the edge of the material tray disappears instantly. At this time, there is an attraction between the bar magnet block and the right-angled trapezoidal magnet block, which makes the right-angled trapezoidal magnet block move along the slideway. When the annular part rises in the opposite direction, the edge of the material tray is freed from the restraint of the right-angled trapezoidal magnet block, and the material tray will remain in the discharge bin.

[0047] In addition, the inner wall of the annular portion cooperates with the outer wall of the discharge bin and the collection bin, so that the trays can be neatly stacked together. A limit plate 118 is also fixed on the annular portion to limit the position of the trays. The cross section of the strip portion in the U-shaped groove is square, and the cross section in the slideway is circular. This design ensures that the sleeve can move smoothly along the track of the U-shaped groove.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
