[0002] In today's increasingly popular automation production, efficient and accurate processing of various workpieces and materials has become a key link in the production process. As an important container for storing workpieces, the production of trays is often mass-produced due to the large amount required. Currently, for the tray, most of them are only mechanically fed and discharged.

[0003] However, the existing tray automatic stock bin mostly first adsorbs the tray through the suction cup assembly, then transfers the tray to the discharge station, the discharge station has a loading plate and a liftable bracket below. After the tray is transferred to the loading plate and is limited, the loading plate cancels the limit when the suction cup assembly falls off the tray, and the tray falls on the bracket below, and then the bracket moves to the next station and waits for the next tray.

[0004] Since the tray is generally made of plastic material, it is light in weight. When the tray is transferred to the loading plate, the suction cup in the suction cup assembly may still adsorb the tray after the suction cup assembly stops adsorbing it, affecting the subsequent collection.

[0016] In order to make the patent purposes, technical solutions and advantages of the present application clearer, the following will be further described in detail with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application and do not limit the present application.

[0017] In order to illustrate the technical solutions of the present application, the following will be described by specific examples.

[0018] In order to facilitate the description, only parts related to the embodiments of the present application are shown.

[0019] In combination with Figures 1-3As shown, the automatic material tray hopper includes a housing 1. Inside the housing 1, from top to bottom, there are loading and unloading components, a horizontally movable carrier plate 2, and a pair of liftable brackets 3. The carrier plate 2 has a central opening 4. The carrier plate 2 is equipped with a pair of left and right clamping cylinders 5. The clamping cylinders 5 are equipped with clamping plates 6. The clamping plates 6 have stops 7 at both ends. The clamping plates 6 have a clearance opening 8 in the middle and on the bottom surface. The clamping plates 6 are equipped with support blocks 9 on both sides of the clearance opening 8 below the clamping plates 6. The back of the clamping plates 6 is equipped with a pair of air rods 10. The drive shaft of the air rods 10 is equipped with a Z-shaped pressure plate 11. The upper edge of the pressure plate is higher than the support block. The front end of the pressure plate 11 extends out of the clearance opening 8.

[0020] As an important container for storing workpieces, the production of material trays is often carried out in large batches due to the large quantities required. This device can automatically collect the finished material trays.

[0021] After the produced trays are delivered one by one to the loading station, the loading / unloading assembly first picks up the tray and moves it towards the chassis, at which point the carrier plate is located at the unloading station. After the loading / unloading assembly transfers the tray to the carrier plate, the carrier plate limits the tray, causing it to detach from the loading / unloading assembly. The loading / unloading assembly then resets and prepares to move the next tray. Next, the carrier plate releases the limit on the tray, and finally, the tray falls onto the corresponding tray below for stacking. Once the tray is stacked on the tray, the tray moves downwards one station, waiting for the next tray to be placed on top.

[0022] In this device, such as Figure 1 The loading and unloading assembly includes a suction cup moving module 12. The moving end of the suction cup moving module 12 is provided with a lifting cylinder 13 facing downward. The drive shaft of the lifting cylinder 13 is provided with a rotary cylinder 14. The drive shaft of the rotary cylinder 14 is provided with a suction cup frame 15. A set of suction cups 16 are provided on the suction cup frame 15.

[0023] In this structure, the carrier plate is provided with a pair of left and right clamps, with stop blocks at both ends of the clamps and a support block below. The clamps, stop blocks, and support blocks constitute a limiting range.

[0024] After the suction cup adheres to the material tray, it is transferred to the unloading station by the conveying action of the suction cup moving module, with the tray directly above the carrier plate. Then, the suction cup can be rotated slightly by a rotary cylinder to bring the tray directly opposite the carrier plate. A lifting cylinder drives the tray downwards a short distance until it is positioned within the central opening. Immediately afterwards, two clamping cylinders simultaneously drive two clamping plates towards the tray until both sides of the tray are positioned between the pressure plate and the support block. Then, the suction cup releases its grip on the tray, and it falls within the limit range.

[0025] Because the tray is generally made of plastic material, its weight is relatively light. When the suction plate cancels the suction on the tray, in order to ensure that the tray is completely separated from the suction plate, the two pairs of air rods simultaneously drive the two pressing plates to move downward by a small distance until the pressing plates and the supporting blocks on the same side clamp the tray. In this way, the suction plate can be smoothly separated from the tray. Finally, the carrier plate moves to the position directly above the corresponding bracket, the two clamping plates move backward by a small distance, and the tray is stacked on the bracket. The bracket moves downward by one station and waits for the next tray to be stacked.

[0026] As a preferred structure, as shown in Figure 3 , a pair of fixed plates 17 are arranged below the case 1, a pair of sliding sleeves 18 are arranged on the fixed plates 17, sliding rods 19 are inserted into the sliding sleeves 18, the bracket 3 is arranged above the sliding rods 19, and a bottom plate 20 is arranged below the sliding rods 19. A silk sleeve 181 is further arranged on the fixed plate 17. A lead screw 21 is rotatably arranged between the bracket 3 and the bottom plate 20, the lead screw 21 is located in the silk sleeve 181, the lead screw 21 penetrates through the bottom plate 20 and is provided with a driven wheel 22 below. A lifting motor 23 is arranged on the bottom plate 20. A driving wheel 24 is arranged on the driving shaft of the lifting motor 23. A belt 25 is sleeved between the driving wheel 24 and the driven wheel 22.

[0027] Before the tray is stacked on the bracket, the bracket is located at the highest position and is arranged opposite to the middle opening. The bracket is only a small distance away from the middle opening. When the clamping plate cancels the limiting of the tray, the tray falls on the bracket. Then the bracket moves downward by a small distance and waits for the next tray to be stacked on the current tray.

[0028] In the structure, the sliding rod, the bracket, and the bottom plate form a lifting frame. When the bracket needs to move downward by one station, the lifting motor drives the driving wheel to rotate. Under the linkage of the belt, the lead screw rotates. In the process of rotating, under the action of the silk sleeve, the lifting frame as a whole moves downward by one station. The lifting motor stops working. In the figure, the lifting frame is located at the lowest position.

[0029] As a specific structure, as shown in Figure 1 , a horizontal movement module 26 is arranged in the case 1. One side of the carrier plate 2 is slidably installed on the inner wall of the case 1, and the other side is connected with the moving end of the horizontal movement module 26. The carrier plate moves left and right through the horizontal movement module. During the process of collecting the trays, if the right bracket is full of trays, the carrier plate can move left through the horizontal movement module, so that the trays can be stacked on the left bracket. At the same time, a stack of trays on the right bracket is taken out. The whole collecting process does not need to be stopped, which effectively improves the work efficiency.

[0030] In addition, as shown in Figure 3The tray 3 is provided with a material collecting seat 27 on the sliding surface, a notch is formed on the rear side of the material collecting seat 27, and a resisting plate 29 is arranged downward in the notch, and a handle 30 is arranged on the resisting plate 29.

[0031] When the lifting frame is lowered to the lowest position, the tray on the lifting frame is full of material trays. The rear side of the machine box is provided with a box door, at this time, the box door is opened, the material collecting seat is pulled out of the machine box by a distance through the handle, and the material trays are walked to be stacked. Finally, the material collecting seat is reversely pushed by the handle until the resisting plate is abutted against the corresponding position of the tray, and the material collecting seat is reset.

[0032] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
