Description

Technical Field

[0001] The utility model relates to the technical field of material transfer, in particular to a material transfer device and a material assembly system. Background Art

[0002] Workbenches are essential tooling in manufacturing, especially assembly. Traditional workbenches are relatively simple, providing only a single surface for work. This lacks flexibility and makes it difficult to switch between different processes. Furthermore, due to the limited size of the workbenches, multiple workbenches are often required to complete a complete assembly line. Simultaneous operation of multiple workbenches not only takes up a significant amount of space, but also requires manual handling for material transfer between different processes, resulting in significant handling waste. The production process is entirely manual, without auxiliary tooling, which can easily lead to significant wasted motion.

[0003] The production of some products requires multiple steps, including applying sponges, labeling, and riveting. Due to limited workbench space, the sheer volume of materials is difficult to arrange. Retrieving materials is also difficult for employees, who frequently bend and turn. After completing one process, they must manually transfer the materials to another workbench for the next step.

[0004] Therefore, it is necessary to find a material handling device that can reduce the frequent bending and turning operations of employees and is suitable for use between workbenches. Utility Model Content

[0005] In order to overcome the problems existing in the related technology, one of the purposes of the present utility model is to provide a material transfer device, which realizes automatic adjustment of the position of the storage box through the difference in the mass of the pulling component, the storage box and the internal material, thereby avoiding manual material handling and improving the efficiency of material transmission.

[0006] A material transfer device comprises a transmission slide rail, wherein the angle between the transmission slide rail and the horizontal plane is greater than 0°; a slidable material storage box is provided in the transmission slide rail, and a tension component is provided on the side of the material storage box close to the top of the transmission slide rail; the tension component exerts a constant tension on the material storage box;

[0007] When the gravity of the storage box and the material inside is less than or equal to the pulling force of the pulling component on the storage box, the storage box slides to the top of the transmission slide rail; when the gravity of the storage box and the material inside is greater than the pulling force of the pulling component on the storage box, the storage box slides to the bottom of the transmission slide rail.

[0008] In a better technical solution of the present invention, the storage box is connected to a limit assembly; the limit assembly can make the storage box slide toward the top end of the transmission slide rail, and can prevent the storage box from sliding toward the bottom end of the transmission slide rail; the limit assembly is connected to a control component, and the control component can drive the limit assembly to move toward or away from the storage box.

[0009] The purpose of the present application to set the limit assembly is to control the timing of the material storage box sliding toward the bottom end of the transmission slide rail. Only when the limit assembly does not act on the material storage box can the material storage box slide toward the bottom end of the transmission slide rail. When the limit assembly acts on the material storage box, even if the gravity of the material storage box and the internal materials is greater than the force of the tension assembly, the material storage box will not move. The purpose of the present application to set the limit assembly is to ensure that the material storage box is filled with materials before the transmission and sliding begins. It is only necessary to set the tension of the tension assembly on the material storage box to be greater than the initial gravity of the material storage box, thereby avoiding energy consumption caused by setting the tension of the tension assembly too large. Moreover, the sliding timing of the material storage box can be manually controlled by the limit assembly, thereby improving the diversified design of material transportation.

[0010] In a preferred technical solution of the present invention, the tension component is a counterweight block, and the counterweight block is connected to the storage box via a first connecting line; when the gravity of the counterweight block is greater than or equal to the gravity of the storage box and the material inside, the counterweight block drives the storage box to slide to the top of the transmission slide rail;

[0011] When the gravity of the counterweight block is less than the gravity of the material storage box and the material inside, and the limiting component acts on the material storage box, the material storage box is limited at the top end of the transmission slide rail;

[0012] When the gravity of the counterweight block is less than the gravity of the material storage box and the material inside, and the limiting component does not act on the material storage box, the material storage box slides to the bottom end of the transmission slide rail.

[0013] The gravity of the counterweight block of the present application is constant, that is, the pulling force acting on the storage box is constant, and the pulling force on the storage box is greater than the gravity of the empty storage box. In this way, when there is no material in the storage box, the counterweight block drives the storage box to slide to the top of the transmission slide rail. At this time, no matter whether the limiting assembly acts on the storage box, the storage box can slide to the top of the transmission slide rail. As the material in the storage box increases, the limiting assembly acts on the storage box so that it cannot slide towards the bottom of the transmission slide rail. Only when the storage box is filled with material or meets the transportation adjustment, the control component drives the limiting assembly away from the storage box, that is, the limiting assembly does not act on the storage box. At this time, the storage box slides to the bottom of the transmission slide rail under the action of gravity, realizing the transmission of the storage box from the top to the bottom of the transmission slide rail. The counterweight block has a simple structure and is easy to operate, which simplifies the structure of the transport device.

[0014] In a preferred technical solution of the present utility model, the limiting assembly includes a first connecting tube located below the storage box, a second connecting tube located below the first connecting tube, and a one-way rotating member provided between the second connecting tube and the second connecting tube;

[0015] The first connecting tube is fixedly connected to the material storage box, the second connecting tube is connected to the control member, and the control member can drive the second connecting tube to move toward or away from the first connecting tube.

[0016] In the present application, the first connecting tube is fixedly connected to the material storage box, the second connecting tube can be raised and lowered relative to the first connecting tube, and a one-way rotating member is provided between the first connecting tube and the second connecting tube. The one-way rotating member enables the first connecting tube to slide toward the top end of the transmission slide rail, but cannot slide toward the bottom end of the transmission slide rail, that is, the one-way rotating member limits the first connecting tube, ensuring that the material storage box can only slide toward the top end of the transmission slide rail, but cannot slide toward the bottom end of the transmission slide rail. The present application achieves unidirectional limitation of the material storage box through the cooperation of the first connecting tube, the second connecting tube and the one-way rotating member, and has a simple structure, precise limiting, and improves the convenience of the material transfer device.

[0017] In a better technical solution of the present invention, the one-way rotating part includes a third connecting tube and a rotating plate. The third connecting tube is fixed to the top end of the second connecting tube and is arranged perpendicular to the extension direction of the transmission slide rail. The rotating plate is hinged to the third connecting tube, and the rotating plate is located on the side of the third connecting tube close to the bottom end of the transmission slide rail.

[0018] The present application further splits the one-way rotating member into a rotating plate and a third connecting tube. The third connecting tube serves to limit the rotating plate in one direction. That is, the one-way rotating member is located on the side of the third connecting tube that is close to the bottom end of the transmission slide rail, and the top of the one-way rotating member is located between the first connecting tube and the second connecting tube. When the limiting assembly acts on the storage box, the top of the rotating plate is located at the hollow position between the first connecting tube and the second connecting tube, and because the bottom end of the rotating plate is limited by the third connecting tube, the rotating plate can only rotate toward the side close to the top end of the transmission slide rail, and cannot rotate toward the side close to the bottom end of the transmission slide rail. Through the cooperation of the rotating member and the third connecting tube, the limiting assembly can limit the storage box in one direction, and the structure is simple and the limiting is precise, thereby improving the limiting accuracy of the limiting assembly.

[0019] In a preferred technical solution of the present invention, the rotating plate includes a fixed portion and a rotating portion, the fixed portion is located at the center of the rotating plate, the rotating portion is located on the outer periphery of the fixed portion, and the fixed portion is hinged to the third connecting tube.

[0020] The rotating plate of the present application is a planar structure, in which the fixed portion at the center is hinged to the rotating plate, and the top of the rotating portion on the outer peripheral side of the fixed portion is located between the first connecting tube and the second connecting tube, and can be rotated relative to the fixed portion toward the top of the transmission slide rail, so that the first connecting tube passes over the second connecting tube and slides together with the storage box toward the top of the transmission slide rail. After the first connecting tube passes over the second connecting tube, the rotating portion is reset. When the gravity of the storage box and the material inside is greater than the gravity of the counterweight block, the top of the rotating plate cannot move toward the bottom of the transmission slide rail because the bottom of the rotating plate is limited by the second connecting tube, so that the first connecting tube cannot pass over the second connecting tube and move toward the bottom of the transmission slide rail, thereby achieving unidirectional limitation of the storage box. Splitting the rotating plate into the fixed portion and the rotating portion has a simple structure and precise control, thereby improving the limiting accuracy of the limiting component.

[0021] In a preferred technical solution of the present invention, a transfer frame is further included, and a transmission slide rail is provided on the top of the transfer frame;

[0022] A fourth connecting pipe is provided on the side of the second connecting pipe, the fourth connecting pipe is provided parallel to the second connecting pipe, and the fourth connecting pipe is fixedly connected to the transfer frame;

[0023] The second connecting tube is slidably connected to the fourth connecting tube. The control member is connected to the second connecting tube and can drive the second connecting tube to rise and fall relative to the fourth connecting tube, so that the rotating plate moves away from or close to the first connecting tube.

[0024] In the present application, the control member is used to control whether the limiting assembly acts on the material storage box. Specifically, the control member can drive the distance between the second connecting tube and the first connecting tube to achieve control of the storage box limit. When the distance between the first connecting tube and the second connecting tube is greater than the height of the rotating plate, the first connecting tube is not affected by the limiting effect of the second connecting tube, that is, the limiting assembly will not act on the material storage box; when the distance between the first connecting tube and the second connecting tube is less than the height of the rotating plate, the first connecting tube is affected by the limiting effect of the second connecting tube, that is, the limiting assembly acts on the material storage box, achieving limitation of the unidirectional movement of the material storage box. The first connecting tube and the fourth connecting tube of the present application are fixed. By controlling the position of the second connecting tube relative to the fourth connecting tube, the distance between the first connecting tube and the second connecting tube can be controlled. The structure is simple, the control is precise, and the limiting accuracy of the limiting assembly is improved.

[0025] In a preferred technical solution of the present invention, a sheath is provided on the outer side of the second connecting pipe, one end of the sheath is slidably connected to the second connecting pipe, and the other end of the sheath is fixedly connected to the fourth connecting pipe.

[0026] The present application ensures that the second connecting tube is accurately raised and lowered relative to the fourth connecting tube by nesting the sheath outside the second connecting tube, and can ensure the sliding stability of the second connecting tube, thereby improving the limiting accuracy of the limiting assembly.

[0027] In a preferred technical solution of the present invention, the control component is a foot pedal, and the foot pedal is connected to the second connecting pipe via a second connecting line.

[0028] When the operator steps on the foot pedal, the second connecting tube moves away from the first connecting tube, meaning the limit assembly does not act on the storage box. When the foot pedal is released, the second connecting tube moves closer to the first connecting tube, meaning the limit assembly acts on the storage box. This application configures the control assembly as a foot pedal, making it easier for the operator to control the timing of the storage box's sliding. As long as the material level in the storage box meets the transmission requirements, the operator can step on the foot pedal, causing the storage box to drive the material toward the bottom of the transmission rail. The provision of the foot pedal in this application diversifies the timing of material transmission, making it suitable for material transmission in different scenarios and increasing the diversity of material transfer.

[0029] A second object of the present application is to provide a material assembly system, comprising at least two workbenches, and a material transfer device as described above, wherein the material transfer device is arranged between two adjacent workbenches.

[0030] The beneficial effects of the utility model are:

[0031] The utility model provides a material transfer device, including a transmission slide rail, wherein the angle between the transmission slide rail and the horizontal plane is greater than 0°; a slidable material storage box is provided in the transmission slide rail, and a tension component is provided on the side of the material storage box close to the top of the transmission slide rail; the tension of the tension component on the material storage box is constant; the top of the transmission slide rail refers to the end of the transmission slide rail that is higher than the horizontal plane. The storage box of the present application is used to hold materials. When no materials are held or when materials are just being held, the gravity of the storage box and the materials inside is less than or equal to the pulling force of the tension component on the storage box. At this time, the tension component drives the storage box to slide to the top of the transmission slide rail; as the materials are continuously loaded into the storage box, the gravity of the storage box and the materials inside is greater than the pulling force of the tension component on the storage box. At this time, under the action of gravity, the storage box slides to the bottom of the transmission slide rail; the present application utilizes the weight relationship between the tension component, the storage box and the materials inside to realize automatic sliding of the storage box, and then realizes the transfer of materials in the storage box, avoids frequent manual handling of materials, and improves the efficiency of material transmission.

[0032] The present application also provides a material assembly system, comprising at least two workbenches and a material transfer device as described above, wherein the material transfer device is arranged between two adjacent workbenches. The material transfer device can realize automatic transfer of materials between the two workbenches, thereby improving the efficiency of material transfer. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following describes preferred embodiments of the present invention in more detail with reference to the accompanying drawings. Although preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, the first information may also be referred to as the second information, and similarly, the second information may also be referred to as the first information.

In the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0044] Example 1

[0045] like Figures 1-4 As shown, the present embodiment provides a material transfer device, including a transmission slide 11, wherein the angle between the transmission slide 11 and the horizontal plane is greater than 0°; a slidable material storage box 12 is provided in the transmission slide 11, and a tension component is provided on the side of the material storage box 12 close to the top of the transmission slide 11; the tension of the tension component on the material storage box 12 is constant; when the gravity of the material storage box 12 and the material inside is less than or equal to the tension of the tension component on the material storage box 12, the material storage box 12 slides to the top of the transmission slide 11; when the gravity of the material storage box 12 and the material inside is greater than the tension of the tension component on the material storage box 12, the material storage box 12 slides to the bottom of the transmission slide 11.

[0046] The storage box 12 of the present application is used to hold materials. When no materials are held or when materials are just being held, the gravity of the storage box 12 and the materials inside is less than or equal to the pulling force of the pulling component on the storage box 12. At this time, the pulling component drives the storage box 12 to slide to the top of the transmission slide 11; as the materials are continuously loaded into the storage box 12, the gravity of the storage box 12 and the materials inside is greater than the pulling force of the pulling component on the storage box 12. At this time, under the action of gravity, the storage box 12 slides to the bottom of the transmission slide 11; the present application utilizes the weight relationship between the pulling component and the storage box 12 and the materials inside to realize the automatic sliding of the storage box 12, and then realizes the transportation of materials in the storage box 12, avoiding frequent manual handling of materials and improving the efficiency of material transmission.

[0047] The present application can control the sliding timing of the material storage box 12 by controlling the pulling force of the pulling component on the material storage box 12. When the pulling force of the pulling component on the material storage box 12 is large, the material storage box 12 needs to contain more materials to achieve sliding from the top to the bottom of the transmission slide 11. When the pulling force of the pulling component on the material storage box 12 is small, the material storage box 12 contains less materials, and the material storage box 12 can achieve sliding from the top to the bottom of the transmission slide 11.

[0048] The present application can set up multiple pulling components, or set the pulling force of the pulling component on the storage box 12 to an adjustable state, so that it can adapt to the handling of materials of different weights.

[0049] Example 2

[0050] like Figures 1-4 As shown, the present embodiment provides a material transfer device, including a transmission slide 11, wherein the angle between the transmission slide 11 and the horizontal plane is greater than 0°; a slidable material storage box 12 is provided in the transmission slide 11, and a tension component is provided on the side of the material storage box 12 close to the top of the transmission slide 11; the tension of the tension component on the material storage box 12 is constant; when the gravity of the material storage box 12 and the material inside is less than or equal to the tension of the tension component on the material storage box 12, the material storage box 12 slides to the top of the transmission slide 11; when the gravity of the material storage box 12 and the material inside is greater than the tension of the tension component on the material storage box 12, the material storage box 12 slides to the bottom of the transmission slide 11.

[0051] Furthermore, the storage box 12 is connected to a limit assembly; the limit assembly can make the storage box 12 slide toward the top end of the transmission slide rail 11, and can prevent the storage box 12 from sliding toward the bottom end of the transmission slide rail 11; the limit assembly is connected to a control component, and the control component can drive the limit assembly to move toward or away from the storage box 12.

[0052] The present application sets the limit assembly to control the timing of the storage box 12 sliding toward the bottom of the transmission slide 11. Only when the limit assembly does not act on the storage box 12 can the storage box 12 slide toward the bottom of the transmission slide 11. When the limit assembly acts on the storage box 12, even if the gravity of the storage box 12 and the internal materials is greater than the force of the pulling assembly, the storage box 12 will not move. The present application sets the limit assembly to ensure that the storage box 12 is filled with materials before the transmission and sliding are started, and it is only necessary to set the pulling force of the pulling assembly on the storage box 12 to be greater than the initial gravity of the storage box 12, thereby avoiding the energy consumption caused by the excessive pulling force of the pulling assembly. The limit assembly can also be used to manually control the sliding timing of the storage box 12, thereby improving the diversified design of material transportation.

[0053] Furthermore, the pulling component is a counterweight block 13, and the counterweight block 13 is connected to the storage box 12 through a first connecting line 15; when the gravity of the counterweight block 13 is greater than or equal to the gravity of the storage box 12 and the internal material, the counterweight block 13 drives the storage box 12 to slide to the top of the transmission slide rail 11; when the gravity of the counterweight block 13 is less than the gravity of the storage box 12 and the internal material, and the limiting component acts on the storage box 12, the storage box 12 is limited to the top of the transmission slide rail 11; when the gravity of the counterweight block 13 is less than the gravity of the storage box 12 and the internal material, and the limiting component does not act on the storage box 12, the storage box 12 slides to the bottom end of the transmission slide rail 11.

[0054] The gravity of the counterweight 13 of the present application is constant, that is, the pulling force acting on the storage box 12 is constant, and the pulling force on the storage box 12 is greater than the gravity of the empty storage box 12. In this way, when there is no material in the storage box 12, the counterweight 13 drives the storage box 12 to slide to the top of the transmission slide 11. At this time, no matter whether the limiting component acts on the storage box 12, the storage box 12 can slide to the top of the transmission slide 11. As the material in the storage box 12 increases, the limiting component acts on the storage box 12, making it unable to slide toward the bottom of the transmission slide 11. Only when the storage box 12 is full of material or meets the transport adjustment, the control component drives the limiting component away from the storage box 12, that is, the limiting component does not act on the storage box 12. At this time, the storage box 12 slides to the bottom of the transmission slide 11 under the action of gravity, realizing the transmission of the storage box 12 from the top to the bottom of the transmission slide 11. The counterweight block 13 has a simple structure and is easy to operate, thus simplifying the structure of the transfer device.

[0055] Furthermore, the limiting assembly includes a first connecting tube 21 located below the storage box 12, a second connecting tube 22 located below the first connecting tube 21, and a one-way rotating member arranged between the second connecting tube 22 and the second connecting tube 22; the first connecting tube 21 is fixedly connected to the storage box 12, the second connecting tube 22 is connected to the control member, and the control member can drive the second connecting tube 22 to move toward or away from the first connecting tube 21.

[0056] In the present application, the first connecting tube 21 is fixedly connected to the storage box 12, the second connecting tube 22 can be raised and lowered relative to the first connecting tube 21, and a one-way rotating member is provided between the first connecting tube 21 and the second connecting tube 22. The one-way rotating member enables the first connecting tube 21 to slide toward the top end of the transmission slide 11, but cannot slide toward the bottom end of the transmission slide 11, that is, the one-way rotating member limits the first connecting tube 21, ensuring that the storage box 12 can only slide toward the top end of the transmission slide 11, but cannot slide toward the bottom end of the transmission slide 11. The present application achieves unidirectional limitation of the storage box 12 through the cooperation of the first connecting tube 21, the second connecting tube 22 and the one-way rotating member, and has a simple structure and precise limiting, thereby improving the convenience of the material transfer device.

[0057] Furthermore, the one-way rotating member includes a third connecting tube 23 and a rotating plate. The third connecting tube 23 is fixed at the top end of the second connecting tube 22 and is arranged perpendicular to the extension direction of the transmission slide rail 11. The rotating plate is hinged to the third connecting tube 23, and the rotating plate is located on the side of the third connecting tube 23 close to the bottom end of the transmission slide rail 11.

[0058] The present application further separates the one-way rotating member into a rotating plate and a third connecting tube 23. The third connecting tube 23 serves to limit the rotating plate in one direction. That is, the one-way rotating member is located on the side of the third connecting tube 23 that is close to the bottom end of the transmission slide 11, and the top of the one-way rotating member is located between the first connecting tube 21 and the second connecting tube 22. When the limiting assembly acts on the storage box 12, the top of the rotating plate is located in the hollow position between the first connecting tube 21 and the second connecting tube 22. Since the bottom end of the rotating plate is limited by the third connecting tube 23, the rotating plate can only rotate toward the side closer to the top end of the transmission slide 11, and cannot rotate toward the side closer to the bottom end of the transmission slide 11. Through the cooperation of the rotating member and the third connecting tube 23, the limiting assembly can limit the storage box 12 in one direction. The structure is simple and the limiting is precise, thereby improving the limiting accuracy of the limiting assembly.

[0059] The rotating plate includes a fixed portion 25 and a rotating portion 26 . The fixed portion 25 is located at the center of the rotating plate, and the rotating portion 26 is located on the outer periphery of the fixed portion 25 . The fixed portion 25 is hinged to the third connecting pipe 23 .

[0060] The rotating plate of the present application is a planar structure, with a fixed portion 25 at its center hingedly connected to the rotating plate. The top of the rotating portion 26 on the outer periphery of the fixed portion 25 is located between the first connecting tube 21 and the second connecting tube 22. The rotating portion 26 can rotate relative to the fixed portion 25 toward the top of the transmission slide 11, causing the first connecting tube 21 to pass over the second connecting tube 22 and slide together with the storage box 12 toward the top of the transmission slide 11. After the first connecting tube 21 passes over the second connecting tube 22, the rotating portion 26 returns to its original position. When the gravity of the storage box 12 and the material inside exceeds the gravity of the counterweight 13, the bottom of the rotating plate is limited by the second connecting tube 22, and the top of the rotating plate cannot move toward the bottom of the transmission slide 11, so that the first connecting tube 21 cannot pass over the second connecting tube 22 toward the bottom of the transmission slide 11, thereby achieving unidirectional positioning of the storage box 12. Splitting the rotating plate into the fixed portion 25 and the rotating portion 26 provides a simple structure, precise control, and improved positioning accuracy of the limiting assembly.

[0061] Furthermore, the material transfer device of the present application also includes a transfer frame 10, and a transfer slide rail 11 is provided at the top of the transfer frame 10; a fourth connecting tube 24 is provided on the side of the second connecting tube 22, and the fourth connecting tube 24 is arranged parallel to the second connecting tube 22, and the fourth connecting tube 24 is fixedly connected to the transfer frame 10; the second connecting tube 22 is slidingly connected to the fourth connecting tube 24, and the control part is connected to the second connecting tube 22, and can drive the second connecting tube 22 to rise and fall relative to the fourth connecting tube 24, so that the rotating plate moves away from or close to the first connecting tube 21.

[0062] In the present application, the control member is used to control whether the limit assembly acts on the storage box 12. Specifically, the control member can drive the distance between the second connecting tube 22 and the first connecting tube 21 to achieve the control of the storage box 12 limit. When the distance between the first connecting tube 21 and the second connecting tube 22 is greater than the height of the rotating plate, the first connecting tube 21 is not limited by the second connecting tube 22, that is, the limit assembly does not act on the storage box 12; when the distance between the first connecting tube 21 and the second connecting tube 22 is less than the height of the rotating plate, the first connecting tube 21 is limited by the second connecting tube 22, that is, the limit assembly acts on the storage box 12, achieving the limit of the unidirectional movement of the storage box 12. The first connecting tube 21 and the fourth connecting tube 24 of the present application are fixed. By controlling the position of the second connecting tube 22 relative to the fourth connecting tube 24, the distance between the first connecting tube 21 and the second connecting tube 22 can be controlled. The structure is simple, the control is precise, and the limit accuracy of the limit assembly is improved.

[0063] Furthermore, a sheath 20 is provided on the outer side of the second connecting tube 22 , one end of the sheath 20 is slidably connected to the second connecting tube 22 , and the other end of the sheath 20 is fixedly connected to the fourth connecting tube 24 .

[0064] The present application ensures that the second connecting tube 22 is accurately raised and lowered relative to the fourth connecting tube 24 by nesting the sheath 20 outside the second connecting tube 22, and ensures the sliding stability of the second connecting tube 22, thereby improving the limiting accuracy of the limiting assembly.

[0065] Furthermore, the control component is a foot pedal 28 , and the foot pedal 28 is connected to the second connecting pipe 22 via a second connecting line 29 .

[0066] When the operator steps on the foot pedal 28, the second connecting tube 22 moves away from the first connecting tube 21, that is, the limit assembly does not act on the storage box 12. When the foot pedal 28 is released, the second connecting tube 22 moves closer to the first connecting tube 21, that is, the limit assembly acts on the storage box 12. The present application sets the control component as the foot pedal 28, which facilitates the operator to control the sliding timing of the storage box 12. As long as the material content in the storage box 12 meets the transmission requirements, the foot pedal 28 can be stepped on, causing the storage box 12 to drive the material to slide toward the bottom of the transmission slide 11. The provision of the foot pedal 28 in the present application diversifies the timing of material transmission, is suitable for material transmission in different scenarios, and increases the diversity of material transportation.

[0067] Example 3

[0068] like Figures 1-4 As shown, a material transfer device provided by this embodiment includes a transfer slide 11, and the angle between the transfer slide 11 and the horizontal plane is greater than 0°; the transfer slide 11 is located at the top of the transfer frame 10, and the transfer frame 10 is constructed of multiple lean tubes in the horizontal and vertical directions. The top of the transfer frame 10 is a horizontal plane, and the transfer slide 11 is tilted and arranged at the top of the transfer frame 10. The transfer slide 11 can be set as two parallel ones, and the two transfer slides 11 are used to carry the storage box 12 from both sides. A stop block is provided at the top of the transfer slide 11 for limiting the storage box 12 to prevent the storage box 12 from sliding out of the transfer slide 11.

[0069] The transmission slide 11 is provided with a slidable material storage box 12 for containing materials. The material storage box 12 is provided with a tension component on one side close to the top of the transmission slide 11. Figure 1A tensioning assembly is provided on the left side of the central storage box 12; this assembly is a counterweight 13, which is connected to the storage box 12 via a first connecting cable 15. Specifically, to facilitate routing of the first connecting cable 15, a roller 17 and a ball hook 14 are provided in the transfer frame 10 or the transport rail 11. The first connecting cable 15 can pass over these rollers and ball hooks, connecting to the counterweight 13 and the storage box 12, respectively. The counterweight 13 is suspended in the hollow of the transfer frame 10. The roller 17 can be a fixed pulley.

[0070] The storage box 12 of the present application is connected to a limiting assembly; the limiting assembly is connected to a control member, and the control member can drive the limiting assembly to move toward or away from the storage box 12.

[0071] Specifically, the limiting assembly includes a first connecting tube 21 located below the storage box 12, a second connecting tube 22 located below the first connecting tube 21, and a one-way rotating member arranged between the second connecting tube 22 and the second connecting tube 22; the first connecting tube 21 is fixedly connected to the storage box 12, the second connecting tube 22 is connected to the control member, and the control member can drive the second connecting tube 22 to move toward or away from the first connecting tube 21.

[0072] The one-way rotating member includes a third connecting tube 23 and a rotating plate. The third connecting tube 23 is fixed to the top end of the second connecting tube 22 and is arranged perpendicular to the extension direction of the transmission slide rail 11. The rotating plate is hinged to the third connecting tube 23, and the rotating plate is located on the side of the third connecting tube 23 close to the bottom end of the transmission slide rail 11.

[0073] The rotating plate includes a fixed portion 25 and a rotating portion 26. The fixed portion 25 is located at the center of the rotating plate, and the rotating portion 26 is located on the outer periphery of the fixed portion 25. The fixed portion 25 is hingedly connected to the third connecting tube 23. Specifically, the fixed portion 25 can be fixed in the third connecting tube, and the rotating portion 26 and the fixed portion 25 are rotatably connected via a bearing 27 to ensure that the rotating portion 26 can rotate relative to the fixed portion 25.

[0074] A fourth connecting tube 24 is provided on the side of the second connecting tube 22, and the fourth connecting tube 24 is provided parallel to the second connecting tube 22, and the fourth connecting tube 24 is fixedly connected to the transfer frame 10; the second connecting tube 22 and the fourth connecting tube 24 are slidably connected, and the control member is connected to the second connecting tube 22, and can drive the second connecting tube 22 to rise and fall relative to the fourth connecting tube 24, so that the rotating plate moves away from or close to the first connecting tube 21.

[0075] In the present application, the first connecting tube 21, the second connecting tube 22, and the fourth connecting tube 24 are vertical lean tubes, and the third connecting tube 23 is a horizontal lean tube. A sheath 20 is provided on the outside of the second connecting tube 22, one end of the sheath 20 being slidably connected to the second connecting tube 22, and the other end of the sheath 20 being fixedly connected to the fourth connecting tube 24.

[0076] The control element is a foot pedal 28, which is connected to the second connecting tube 22 via a second connecting cable 29. To facilitate the routing of the second connecting cable 29, a roller 17 and a ball hook 14 are provided in the transfer frame 10 or the transport rail 11. The second connecting cable 29 can pass around the roller 17 and the ball hook 14 and connect to the counterweight 13 and the storage box 12, respectively. The counterweight 13 is suspended in the hollow of the transfer frame 10. The roller 17 can specifically be a fixed pulley.

[0077] When building the transfer device of the present application, the length, width, height and other dimensions of the workbench are first determined according to the usage requirements, and lean tubes of appropriate lengths are selected. Then, connectors of various types are assembled at the connection parts of the lean tubes and fixed with screws to form a transfer frame 10.

[0078] The transfer rail 11 is mounted on top of the transfer frame 10 using a lean tube, connector, and ball hook, forming the transfer rail 11. The angle of the transfer rail 11 can be adjusted to the desired angle. A storage box 12 is placed within the transfer rail 11. A first connecting tube 21 is secured to the bottom of the storage box 12. The second, third, and fourth connecting tubes 22, 23, and 24, along with a one-way rotating member, are then installed in sequence. A first connecting line 15 connects the storage box 12 to the counterweight 13, while a second connecting line 29 connects the second connecting tube 22 to the foot pedal 28.

[0079] The working principle of the transfer device of this embodiment is as follows: In the initial state, there is no material in the storage box 12. At this time, the gravity of the counterweight block 13 is greater than the gravity of the storage box 12. The counterweight block 13 pulls the storage box 12 toward the top of the transmission slide 11 until it hits the stop block 16. In this process, Figures 1-4 As shown, the foot pedal 28 is not pressed, the height of the rotating part 26 located between the first connecting tube 21 and the second connecting tube 22 is greater than the minimum distance between the first connecting tube 21 and the second connecting tube 22, and due to the limiting effect of the third connecting tube 23 on the bottom of the rotating part 26, the rotating plate can only rotate in the clockwise direction and cannot rotate counterclockwise. Therefore, the storage box 12 and the first connecting tube 21 can smoothly pass through the rotating member and the second connecting tube 22 and move to the top of the transmission slide rail 11. It should be noted that when the first connecting tube 21 passes over the second connecting tube 22, the rotating plate is reset.

[0080] The staff begins to place materials into the storage box 12. As the amount of materials increases, the gravity of the storage box 12 and the materials inside becomes greater than the gravity of the counterweight 13. However, since the rotating plate cannot rotate counterclockwise, the top of the rotating plate can only rotate toward the top of the transmission track, and cannot rotate toward the bottom of the transmission track. Therefore, the first connecting tube 21 cannot pass over the second connecting tube 22, that is, the storage box 12 cannot slide toward the bottom of the transmission track. Specifically, the present application can set the second connecting tube 22 on the side of the stop block 16 near the bottom of the transmission track, and in the horizontal direction, the distance between the two is exactly equal to the size of the storage box 12, so that the storage box 12 can be confined between the stop block 16 and the second connecting tube 22.

[0081] When the material storage box 12 is full of material, the foot pedal 28 is stepped on. The foot pedal 28 drives the second connecting tube 22 to descend relative to the fourth connecting tube 24 via the second connecting line 29. Specifically, the sheath 20 nested outside the second connecting tube 22 ensures that the second connecting tube 22 is accurately raised and lowered relative to the fourth connecting tube 24. After the second connecting tube 22 descends, the rotating plate separates from the first connecting tube 21 and no longer limits the first connecting tube 21. At this time, the gravity of the material storage box 12 and the material inside is greater than the gravity of the counterweight 13. Under the action of gravity, the material storage box 12 and the first connecting tube 21 are unobstructed and slide toward the bottom of the transfer track until they slide to the top of the transfer track, completing the transfer of material from the top of the transfer track to the bottom of the transfer track.

[0082] After releasing the foot pedal 28, the second connecting tube 22 and the rotating plate are reset. After the material in the storage box 12 is transferred out, the gravity of the storage box 12 is less than the gravity of the counterweight 13. Under the action of the counterweight 13, the storage box 12 and the first connecting tube 21 pass over the rotating plate and slide to the top of the transmission track, thereby realizing the transfer of materials from the top of the transmission slide rail 11 to the bottom of the transmission slide rail 11.

[0083] Example 4

[0084] This embodiment provides a material assembly system, such as Figure 5 and Figure 6 As shown, from right to left, the first workstation 1, second workstation 2, third workstation 3, and fourth workstation 4 are included. The top of the first workstation 1 is the first workbench, the top of the second workstation 2 is the second workbench, the top of the third workstation 3 is the third workbench, and the bottom of the fourth workstation 4 is the fourth workbench. The material transfer device of Example 3 is located between the third and fourth workbench. Conveyor belts are installed on the sides of the first, second, and third workbench.

[0085] Products are processed in an assembly line, starting at workstation 1 and moving leftward. Products and auxiliary materials, such as sponge screws, are placed on a shelf opposite the workbench. Workstation 1 begins taking materials and assembling them on the first workbench. After assembly, the materials are placed on a conveyor belt and transported to the second workbench. Further processing occurs at the second workbench, and the finished products are placed on a conveyor belt and transported to the third workbench. Workers at workstation 3 place the finished products in a material storage box 12.

[0086] There is no material in the storage box 12. At this time, the gravity of the counterweight 13 is greater than the gravity of the storage box 12. The counterweight 13 pulls the storage box 12 toward the top of the transmission slide 11 until it touches the stop block 16. Figures 1-4 As shown, the foot pedal 28 is not stepped on, the height of the rotating portion 26 located between the first connecting tube 21 and the second connecting tube 22 is greater than the minimum distance between the first connecting tube 21 and the second connecting tube 22, and due to the limiting effect of the third connecting tube 23 on the bottom of the rotating portion 26, the rotating plate can only rotate in the clockwise direction and cannot rotate counterclockwise. Therefore, the storage box 12 and the first connecting tube 21 can smoothly pass through the rotating member and the second connecting tube 22 and move to the top of the transmission slide rail 11.

[0087] When the product in the storage box 12 accumulates to a certain amount, the weight of the storage box 12 + the product is greater than the counterweight 13, and the storage box 12 has the potential energy to slide downhill to the left of the transmission track, but due to the obstruction of the rotating plate, the first connecting tube 21 is supported by the rotating plate and remains stationary.

[0088] When the storage box 12 is full of product, the pedal 28 is stepped on, the rotating plate slides downward along with the second connecting pipe 22, the first connecting pipe 21 is no longer blocked, and the entire storage box 12 slides downhill to the left of the sliding track to the leftmost side. At this time, the pedal 28 is released, and the second connecting pipe 22 and the rotating plate slide upward to return to their original positions.

[0089] After the storage box 12 slides to the far left, the employee at the fourth station 4 takes out the stacked products for assembly, and the storage box 12, which has lost the weight of the products, is pulled to the far right by the counterweight block 13 to return to its original position.
