[0002] At present, the material turnover used in conjunction with a robotic arm is usually a "one-to-one" model, that is, one robotic arm is equipped with one silo. In order to improve the work efficiency of the production line, multiple robots are usually introduced to operate simultaneously. At this time, if the "one-to-one" model is adopted, the floor space of the production line will be greatly increased. Therefore, it is necessary to provide a silo that can fully utilize the storage performance of the silo and improve the utilization rate.

[0003] To this end, the utility model with the authorization announcement number CN208453529U discloses a double-layer material tray type silo, including a support frame, a relatively parallel slide rail bracket is arranged on both sides of the upper end surface of the support frame, a first slide rail is arranged on the upper end surface of the slide rail bracket, a second slide rail is arranged on the outer side of the slide rail bracket, and the second slide rail is slidably connected to the second material tray support frame through a second slider matched therewith, and two relatively parallel second material tray support frames support the second material tray, and the upper end surface of the support frame is located between the two slide rail brackets and provided with a first conveyor belt, one end of the first conveyor belt is fixed to the first roller, and the other end is fixed to the output end of the first motor, one side of the first conveyor belt is fixedly connected to the bottom of the first material tray through a first fixing plate, one end of the second conveyor belt is fixed to the output end of the second motor, and the other end is connected to the second roller, and one side of the second conveyor belt is fixedly connected to the upper second material tray support frame through a second fixing plate. The silo of the utility model can simultaneously transport double-layer materials. Obviously, the technical solution of the utility model requires a first motor and a second motor, which greatly increases the manufacturing cost. Utility Model Content

[0004] The present application is aimed at the problem of high manufacturing cost of the above-mentioned double-layer material tray, and particularly proposes a double-layer material tray used for a robot arm to grab materials. The double-layer material tray includes a workbench, a slide rail fixing plate, a loading tray, a loading tray slide rail, a loading tray slider, a lowering tray, a lowering tray slide rail and a lowering tray slider. The workbench is fixed with a slide rail fixing plate, and relatively parallel loading tray slide rails and lowering tray slide rails are arranged on both sides of the plane of the slide rail fixing plate. A loading tray matching the loading tray slide rails is arranged on the loading tray slide rails. The slider is provided on the slide rail of the lower material tray, and the slider of the lower material tray matches the slide rail of the lower material tray. The upper material tray is higher than the lower material tray, and the lower material tray can pass through the lower part of the upper material tray. It is characterized in that it also has a driving cylinder and a conveyor belt. The driving cylinder drives the lower material tray to move and displace. The conveyor belt is adjacent to the lower material tray and the upper material tray. The conveyor belt is connected and fixed to the lower material tray, and the conveyor belt is connected and fixed to the upper material tray. When the driving cylinder drives the lower material tray to move, the position rotation of the turnover boxes on the lower material tray and the upper material tray is realized without interfering with each other. This solution only uses a single driving cylinder to realize the movement of the upper material tray and the lower material tray, and has the advantage of low manufacturing cost.

[0005] Preferably, the driving cylinder and the unloading tray are connected and fixed by a connecting piece.

[0006] Preferably, pulleys are provided at the front and rear positions of the slide rail fixing plate, and the conveyor belt is provided on the front and rear pulleys.

[0007] Preferably, the driving cylinder and the conveyor belt are arranged on the slide rail fixing plate, and the arrangement direction of the driving cylinder and the conveyor belt is parallel to the moving direction of the unloading tray slider.

[0008] Preferably, the loading tray has a loading tray frame, and the lower loading tray has a lower loading tray frame, and both the loading tray frame and the lower loading tray frame are used to hold turnover boxes, and materials are placed in the turnover boxes.

[0009] Preferably, the upper material tray slider is fixedly arranged at the bottom of the vertical plates on both sides of the upper material tray; a lower material tray slide rail is provided on the lower material tray slide rail, and the lower material tray slider is fixedly arranged at the bottom of the vertical plates on both sides of the lower material tray; the lower material tray slide rail is arranged on the outer side of the slide rail fixing plate, and the lower material tray slide rail is arranged on the inner side of the slide rail fixing plate.

[0010] Preferably, the driving cylinder uses a magnetically coupled rodless cylinder.

[0011] The advantage of the present application is that the movement of the upper material tray slide rail and the lower material tray slide rail does not interfere with each other, and the movement of the upper material tray together with the turnover box and the movement of the lower material tray together with the turnover box are relatively independent, so that the turnover box containing the material to be processed can be simultaneously switched and transported in double layers. Only a single driving cylinder is used to realize the movement of the upper material tray and the lower material tray, which has the advantage of low manufacturing cost, so that one turnover box can match at least two or more robotic arms to grasp and convey different materials at the same time. The double-layer material tray used for the robotic arm to grasp objects in the present application improves the efficiency of the robotic arm in transporting and processing materials, and the double-layer material tray can be widely used in the machining needs of various robotic arms, and has a high value of promotion and use.

DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described below in conjunction with the accompanying drawings. It should be noted that the description of the following implementation is used to help understand the utility model, but does not constitute a limitation of the utility model. In addition, the technical features involved in each implementation of the utility model described below can be combined with each other as long as they do not conflict with each other.

[0016] Combination Figure 1 and Figure 2 The present application specifically proposes a double-layer material tray used for a robot arm to grab materials. The double-layer material tray is used to improve the work efficiency of the robot arm in grabbing materials. The double-layer material tray includes a workbench 1, a slide rail fixing plate 2, an upper material tray 3, an upper material tray slide rail 32, an upper material tray slider 33, a lower material tray 4, a lower material tray slide rail 42, a lower material tray slider 43, a driving cylinder 5 and a conveyor belt 6 and other components. The above-mentioned upper material tray 3 has an upper material tray frame 31, and the above-mentioned lower material tray 4 has a lower material tray frame 41. The upper material tray frame 31 and the lower material tray frame 41 are both used to hold turnover boxes, and materials are placed in the turnover boxes.

[0017] A slide rail fixing plate 2 is fixed on the above-mentioned workbench 1, and relatively parallel loading tray slide rails 32 and unloading tray slide rails 42 are provided on both sides of the plane of the slide rail fixing plate 2; a loading tray slider 33 matching the loading tray slide rail 32 is provided on the loading tray slide rail 32, and the loading tray slider 33 is fixedly arranged at the bottom of the vertical plates on both sides of the loading tray 3, and the loading tray slider 33 bears the weight of the entire loading tray 3; a lowering tray slider 43 matching the lowering tray slide rail 42 is provided on the lowering tray slide rail 42, and the lowering tray slider 43 is fixedly arranged at the bottom of the vertical plates on both sides of the lowering tray 4, and the lowering tray slider 43 bears the weight of the entire lowering tray 4; the lowering tray slide rail 42 is arranged on the outer side of the slide rail fixing plate 2, and the lowering tray slide rail 42 is arranged on the inner side of the slide rail fixing plate 2.

[0018] The above-mentioned slide rail fixing plate 2 is also provided with a driving cylinder 5 and a conveyor belt 6 which are parallel to the moving direction of the lower material tray slider 43 (or the upper material tray slider 33). The driving cylinder 5 can drive the lower material tray 4 to move and displace. The driving cylinder 5 and the lower material tray 4 are connected and fixed by a connecting member 51; the conveyor belt 6 is used to drive the movement of the upper material tray 3 and the lower material tray 4. Pulleys are provided at the front and rear positions of the slide rail fixing plate 2. The conveyor belt 6 is provided on the front and rear two pulleys. The conveyor belt 6 is adjacent to the lower material tray 4 and the upper material tray 3. The conveyor belt 6 is connected to the lower material tray 4. The conveyor belt 6 is connected and fixed with the loading tray 3. When the driving cylinder 5 drives the lower feeding tray 4 to move, the loading tray 3 is able to move in the opposite direction through the conveyor belt 6. Since the loading tray 3 is higher than the lower feeding tray 4, the lower feeding tray 4 can pass under the loading tray 3. Only a single driving cylinder 5 is used to realize the movement of the loading tray 3 and the lower feeding tray 4, which has the advantage of low manufacturing cost; the position rotation of the turnover boxes on the lower feeding tray 4 and the loading tray 3 without interfering with each other is realized, thereby satisfying the requirement of the robot arm grabbing the materials to be processed in the turnover box to realize uninterrupted machining.

[0019] In addition, the above-mentioned driving cylinder 5 is preferably a magnetic coupling type rodless cylinder in this embodiment.

[0020] When in use, select the material to be processed and place it in the turnover box, and then place the turnover box on the upper material tray 3 or the lower material tray 4, and the mechanical arm grabs the material in the turnover box. Driven by the driving cylinder 5, the upper material tray 3 and the lower material tray 4 are controlled to move back and forth on the upper material tray slide rail 32 and the lower material tray slide rail 42 through the conveyor belt 6. Since the movement of the upper material tray slide rail 32 and the lower material tray slide rail 42 does not interfere with each other, and the height of the upper material tray 3 is higher than the position height of the lower material tray 4, the movement of the upper material tray 3 together with the turnover box and the movement of the lower material tray 4 together with the turnover box are relatively independent, so that the turnover box containing the material to be processed can be double-layer switched and transported at the same time, so that one turnover box can match at least two or more mechanical arms to grab and transport different materials at the same time. The double-layer material tray used for the mechanical arm to grab objects in this application improves the efficiency of the mechanical arm in transporting materials. The double-layer material tray can be widely used in various processing needs of mechanical arm processing and has a high value of promotion and use.

For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
