[0057] See also Figures 1 to 4The material supply device 1 provided in the present application includes a storage mechanism 10, a feeding mechanism 20 and a screening mechanism 30, wherein the storage mechanism 10 includes a storage piece 11 and a storage drive assembly 12, a storage area 110 for storing workpieces 2 is formed in the middle of the storage piece 11, and the storage drive assembly 12 is driven and connected to the storage piece 11 to drive the volume of the storage area 110 to increase or decrease; the feeding mechanism 20 includes a first conveying platform 21, a second conveying platform 22 and a feeding assembly 23, wherein the first conveying platform 21 surrounds the periphery of the storage piece 11, the second conveying platform 22 surrounds the periphery of the first conveying platform 21, and the first conveying platform 21 and the second conveying platform 22 are coaxially and coplanarly arranged, that is, the first conveying platform 21 and the second conveying platform 22 are coaxially and coplanarly arranged. There is no gap between the platforms 22. At the same time, a feed position 210 is set on the first conveying platform 21, and a discharge position 220 is set on the second conveying platform 22. The conveying speed of the second conveying platform 22 is greater than the conveying speed of the first conveying platform 21, so that the workpieces 2 can be arranged at intervals and output at high speed. The feeding assembly 23 is arranged on the top side of the storage member 11, and is used to send the workpieces 2 in the storage area 110 to the feed position 210; the screening mechanism 30 is arranged between the feed position 210 and the discharge position 220, and is located on the top side of the first conveying platform 21 and the second conveying platform 22, and is used to smoothly transition the workpiece 2 from the first conveying platform 21 to the second conveying platform 22, and make the workpiece 2 output one by one from the discharge position 220 in an ideal posture.

[0058] Specifically, the material storage member 11 can be mounted on the first conveying platform 21 through the fixing member 13, and the feed port 200 of the feeding mechanism 20 can be sealed. Figure 5 As shown, the fixing member 13 is an annular structure, which can be a metal ring, etc. The fixing member 13 surrounds the edge of the material storage member 11 and can press the edge of the material storage member 11 against the side wall or bottom wall of the first conveying platform 21. At the same time, the fixing member 13 is installed on the first conveying platform 21 through the mounting hole opened on the fixing member 13 or the first lug 130 with the mounting hole provided on the fixing member 13; Fig.10As shown, it can be understood that the conveying mechanism 10 also includes a platform driving component 24 and a transmission component 25, wherein the platform driving component 24 can be an electric motor or a hydraulic motor, etc., and the transmission component 25 includes at least two gear sets or two synchronous wheel sets and two synchronous belts, etc., one of the gears of the gear set or one of the synchronous wheels of the synchronous wheel set is connected to the output shaft of the platform driving component 24, the first conveying platform 21 is coaxial with another gear of one of the gear sets or another synchronous wheel of one of the synchronous wheel sets and is fixedly connected, and the second conveying platform 22 is coaxial with another gear of another gear set or another synchronous wheel of another synchronous wheel set and is fixedly connected, so that the first conveying platform 21 and the second conveying platform 22 are driven in coordination with each other by the platform driving component 24 and the transmission component 25 to achieve differential operation of the first conveying platform 21 and the second conveying platform 22.

[0059] Before conveying the workpiece 2 to the automatic assembly equipment or the automatic processing equipment, the workpiece 2 is stored in the storage area 110 of the overall barrel-shaped storage piece 11. When it is necessary to feed the automatic assembly equipment or the automatic processing equipment, the storage drive component 12 is first started to drive the storage piece 11 to deform, so that the volume of the storage area 110 is reduced, and then the workpiece 2 stored in the storage area 110 is lifted up as a whole and gradually exposed outside the storage piece 11. Then the feeding component 23 blows air into the storage area 110 to blow away the workpiece 2 on the top layer. The blown workpiece 2 will fall onto the feeding position 210 of the first conveying platform 21, and then the workpiece 2 is conveyed on the first conveying platform 21. In this process, The screening mechanism 30 arranges the workpieces 2 stacked on the first conveying platform 21 so that the workpieces 2 enter the second conveying platform 22 one by one from the first conveying platform 21. When the workpieces 2 enter the second conveying platform 22 from the first conveying platform 21, since the conveying speed of the second conveying platform 22 is greater than the conveying speed of the first conveying platform 21, the workpieces 2 are arranged on the second conveying platform 22 at a certain interval, and then continue to pass through the screening mechanism 30 in turn. The screening mechanism 30 kicks the workpieces 2 with unqualified posture out of the second conveying platform 22, and then the second conveying platform 22 quickly delivers the workpieces 2 with qualified posture out of the material supply device 1 from the discharge position 220, and finally enters the automatic assembly equipment or automatic processing equipment.

[0060] The material supply device 1 provided in the present application adopts a storage mechanism 10, a feeding mechanism 20 and a screening mechanism 30 to store the workpiece 2 through the deformed storage member 11, and outputs the workpiece 2 to the feeding mechanism 20 when the storage member 11 is driven by the storage drive component 12 to transform from a barrel shape to a disc shape. Since the workpiece 2 is lifted up as a whole during the output process, collision and friction between the workpieces 2 are avoided, and since there is no gap between the first conveying platform 21 and the second conveying platform 22, it is suitable for workpieces 2 of any volume. Since the conveying process is smooth and low-vibration, violent collision or friction between the workpieces 2 will not occur during the conveying process, which effectively reduces the damage of the workpiece 2. At the same time, the second conveying platform 22 can make the workpiece 2 be output at a high speed at a certain spacing, thereby solving the technical problem of how to balance versatility and less damage to achieve storage, screening and high-speed output of workpieces, which is beneficial to ensuring the accuracy of workpiece assembly and improving the production efficiency of workpiece assembly.

[0061] Optionally, see Figure 3 and Figure 4 As a specific embodiment of the material supply device provided in the present application, the material storage member 11 is a sheet elastic member, and the material storage driving assembly 12 includes a traction member 121 and a material storage driving member 122, wherein one end of the traction member 121 is connected to the bottom of the material storage member 11, and the material storage driving member 122 is drivingly connected to the traction member 121. Specifically, the material storage piece 11 is preferably an elastic silicone disc, that is, the material storage piece 11 is made of elastic silicone material, has good elasticity and ductility, and is disc-shaped in the original state, and the material storage area 110 can be a plane or an arc surface that is high in the middle and low on all sides, thereby exposing the workpiece 2 placed on the material storage area 110, making it convenient for the feeding assembly 23 to blow away the workpiece 2; the traction piece 121 can be a wire rope or a screw, etc., and the material storage drive piece 122 can be an electric motor or a pneumatic motor, etc. When the material storage drive piece 122 is started, the material storage piece 11 is stretched downward under the traction of the traction piece 121 to form an inverted frustum or inverted cone-shaped storage barrel, which can store more workpieces 2. When the workpiece 2 needs to be output, the material storage drive piece 122 runs in the opposite direction and gradually releases the traction piece 121. At this time, the volume of the material storage area 110 of the material storage piece 11 will gradually shrink under the action of its own elastic force until it returns to its original shape, so that the material storage piece 11 can realize the storage and feeding functions.

[0062] In the present embodiment, when the traction member 121 is a steel wire rope, the material storage mechanism 10 further includes a pulley 15, which is arranged between the material storage member 11 and the material storage driving member 122 and abuts against the traction member 121. Specifically, the traction member 121 abuts in the slide groove of the pulley 15, and the pulley 15 can guide the movement of the traction member 121, so that the movement process of the traction member 121 is smoother; at the same time, the material storage driving assembly 12 further includes a winding wheel 123, which is sleeved on the driving shaft of the material storage driving member 122, rotates synchronously with the driving shaft, and is connected to the traction member 121. Specifically, the winding wheel 123 includes a main body and two tapered parts, the two tapered parts are symmetrically arranged on the two ends of the main body, and the radius of the tapered part gradually increases from the side close to the main body to the side away from the main body, and the end of the traction member 121 connected to the material storage member 11 is connected to the main body of the winding wheel 123. When the winding wheel 123 rotates synchronously with the driving shaft, the two tapered parts make the traction member 121 always approach the main body and be wound on the main body, that is, the winding wheel 123 can ensure that the traction member 121 will not separate from the driving shaft of the material storage driving member 122 during the winding process.

[0063] Optionally, see Figure 6 and Figure 7 As a specific embodiment of the material supply device provided in the present application, a bottom plate 111 and a spiral spring 112 are embedded in the interior of the material storage member 11, wherein the bottom plate 111 is arranged corresponding to the middle part of the material storage area 110, and the inner end of the spiral spring 112 is fixedly connected to the bottom plate 111. Specifically, the bottom 111 and the spiral spring 112 are molded together with the elastic silicone material, and in the molded storage piece 11, the elastic silicone completely wraps the bottom plate 111 and the spiral spring 112 inside it; the bottom plate 111 here is a circular structure, which is arranged in the middle of the storage piece 11 and is parallel to the bottom surface of the storage piece 11, which can ensure that the storage piece 11 forms a barrel with a certain area of ​​the bottom surface after stretching, thereby preventing the workpieces 2 from being squeezed together due to their accumulation in the middle of the storage area 110, and avoiding damage to the workpieces 2 due to mutual squeezing during the output process; and the spiral spring 112 can increase the elasticity of the storage piece 11, so that the storage piece 11 has a stronger recovery ability and better fatigue resistance, which is beneficial to increase the number of repeated deformations of the storage piece 11, thereby effectively extending the service life of the storage piece 11.

[0064] When the storage member 11 is deformed into a barrel shape, the angle a between the barrel wall of the storage member 11 and the bottom wall of the storage member 11 is greater than or equal to 95 degrees. That is, the barrel wall of the storage member 11 always maintains an inclination angle of not less than 5 degrees with the vertical plane during the transformation between the disc shape and the barrel shape, so that the workpiece 2 slides slowly on the barrel wall of the storage member 11, preventing the workpiece 2 from being damaged due to violent collision and extrusion caused by rapid falling.

The bearing 145 is embedded in the first receiving groove 1432. One end of the positioning member 142 abuts against the bottom surface of the storage member 11, and the other end of the positioning member 142 passes through the first mounting hole 1431 and abuts against the inner ring of the bearing 145.

When two or more stacked workpieces 2 are conveyed on the first horizontal plane 211, the second roller 321 is fixedly sleeved on the output shaft of the second roller driving member 322. When passing the bottom side of the second roller 321, under the limit of the second roller 321, the workpiece 2 that is higher than the lowest posture and close to the second roller 321 will be blocked by the second roller 321 and separated from the workpiece 2 on its bottom side, and then driven by the rotational force of the second roller 321, it leaves the first conveying platform 21 and falls into the feed port 200, thereby ensuring that only one workpiece 2 is retained in the height direction of the first conveying platform 21, and preventing the workpiece 2 from being unable to smoothly leave the first conveying platform 21 and fall into the feed port 200 due to friction.
