Description

Technical Field

[0001] This utility model relates to the field of feeding device technology, and in particular to an alternating loading and unloading device. Background Technology

[0002] In the process of modern manufacturing transforming towards intelligence and automation, loading and unloading devices, as nodes connecting various production links, determine the continuity, efficiency, and space utilization of the production line. With the continuous improvement of product capacity and quality requirements, the pace of production lines is accelerating, placing higher demands on the speed, precision, and structural compactness of loading and unloading devices, especially for conveying components such as displays and glass.

[0003] Currently, in order to improve the efficiency of loading and unloading, some equipment adopts a conveying mode with multiple conveying mechanisms. However, the existing layout design of multiple conveying mechanisms has obvious defects: in most devices, the driving components and fixtures of each conveying mechanism are arranged in a centralized manner, which makes it easy for the movement paths of each conveying mechanism to overlap or cross in space. On the other hand, the dispersed arrangement of each conveying mechanism will occupy too much space.

[0004] Specifically, when one set of conveying mechanisms is performing material handling actions, if another set of conveying mechanisms needs to work synchronously or alternately, its drive components and fixtures are prone to collisions or interference with the working conveying mechanism. To avoid interference, the spacing between each set of conveying mechanisms must be increased, resulting in a large overall structure and significantly increased space occupation, making it difficult to adapt to the limited space of a production workshop. At the same time, due to the unreasonable layout, the coordination of the movement of each set of conveying mechanisms is difficult, and a long avoidance time must be reserved when alternating work, resulting in a longer interval between loading and unloading, making it impossible to achieve continuous and efficient material transfer, and severely restricting the operating speed of the production line. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that in the prior art, the feeding device is not reasonably laid out, the movement coordination of each group of conveying mechanisms is difficult, and a long avoidance time needs to be reserved when alternating work, which leads to the extension of the loading and unloading interval, making it impossible to achieve continuous and efficient material transmission and seriously restricting the operating speed of the production line. Thus, an alternating loading and unloading device is provided.

[0006] To solve the above-mentioned technical problems, this utility model provides an alternating loading and unloading device, comprising:

[0007] frame;

[0008] The first conveying mechanism includes: a first driving member disposed on both sides of the frame, and a first fixture connected to the first driving member;

[0009] The second conveying mechanism includes: a second driving member disposed on both sides of the frame, an extension frame connected to the second driving member, and a second fixture on both sides respectively connected to the extension frame. The conveying directions of the first driving member and the second driving member are parallel. The first driving members on both sides are disposed between the second driving members on both sides. The extension frame extends from the second driving member along the height and width directions of the frame and crosses the first driving member.

[0010] In one embodiment of the present invention, the extension frame includes a first extension portion and a second extension portion. The first extension portion is connected to the output end of the second drive member and extends in the height direction of the frame. The length of the first extension portion is greater than the thickness of the first fixture.

[0011] In one embodiment of the present invention, one end of the second extension is connected to the first extension and the other end extends along the width direction of the frame, the second extensions on both sides extend in a direction that approaches each other, the two ends of the second fixture are respectively connected to the second extensions on both sides, and the width of the second extension is greater than the distance between the first drive member and the second drive member.

[0012] In one embodiment of the present invention, the first conveying mechanism and the second conveying mechanism are disposed on the first side of the frame.

[0013] In one embodiment of this utility model, the first fixture and the second fixture have the same structure. The first fixture is provided with a suction cup assembly, and the suction end of the suction cup assembly faces the second side of the frame.

[0014] In one embodiment of this utility model, the angle between the plane containing the second side of the frame and the ground is an acute angle.

[0015] In one embodiment of the present invention, the first fixture includes: a base plate, a third driving member, and a movable frame. The two sides of the base plate are connected to the first driving member, the third driving member is mounted on the base plate, the movable frame is connected to the output end of the third driving member and moves along the height direction of the frame, and the suction cup assembly is connected to the movable frame.

[0016] In one embodiment of this utility model, the movable frame is disposed on the side of the base plate facing the second side of the frame.

[0017] In one embodiment of the present invention, the third driving component includes: a driving motor disposed on the base plate, a driving screw rotatably connected to the base plate and connected to the output end of the driving motor, and a screw sleeve connected to the movable frame and adapted to the driving screw.

[0018] In one embodiment of this utility model, the movable frame is equipped with a guide sleeve, and the base plate is equipped with a guide rod that slides through the guide sleeve.

[0019] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0020] The alternating loading and unloading device of this utility model effectively avoids spatial interference and achieves continuous alternating operation: By placing the first driving components on both sides between the second driving components on both sides, an inner and outer nested layout is formed. Combined with the design of the extension frame extending along the height and width of the frame and crossing the first driving components, the movement paths of the second fixture and the first fixture are spatially misaligned. This avoids direct contact and collision between the two sets of conveying mechanisms during movement, ensuring that the first and second conveying mechanisms can smoothly and alternately perform material picking and unloading tasks without requiring extra time for avoidance, significantly improving the continuity of loading and unloading.

[0021] 2. Reduced device size and improved space utilization: The nested layout significantly shortens the distance between the two conveyor mechanisms. The extended frame's spanning design utilizes the three-dimensional space in the height and width directions of the frame, avoiding the problem of excessively large lateral or longitudinal dimensions caused by traditional parallel layouts. The overall structure is more compact, significantly reducing the need for installation space and making it more suitable for production workshops with limited space.

[0022] 3. Improved transmission efficiency and docking accuracy: Because the two sets of conveying mechanisms maintain parallel conveying directions and coordinate their movements without interference, they can achieve precise docking with upstream and downstream production and testing equipment, reducing positioning deviations during material transmission. Simultaneously, the alternating working mode eliminates the waiting time loss of a single mechanism, making the loading and unloading rhythm more aligned with the production line speed, effectively improving overall production efficiency.

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0033] Example

[0034] In this embodiment, with Figure 1 Based on this, the height direction of the frame is the front-to-back direction, and the width direction is the left-to-right direction.

[0035] Reference Figures 1-7 As shown, the present invention provides an alternating loading and unloading device, comprising:

[0036] Rack 1;

[0037] The first conveying mechanism includes: a first driving member 2 disposed on both sides of the frame 1, and a first fixture 4 connected to the first driving member 2;

[0038] The second conveying mechanism includes: a second driving member 3 disposed on both sides of the frame 1, an extension frame 6 connected to the second driving member 3, and a second fixture 5 respectively connected to the extension frame 6 on both sides. The conveying directions of the first driving member 2 and the second driving member 3 are parallel. The first driving member 2 on both sides is disposed between the second driving member 3 on both sides. The extension frame 6 extends from the second driving member 3 along the height and width directions of the frame 1 and crosses the first driving member 2.

[0039] The present invention discloses an alternating loading and unloading device, comprising a frame 1, which serves as the mounting foundation and support structure for the entire device, providing a stable mounting platform for each component. A first driving member 2 drives a first fixture 4 to move along a preset direction, thereby moving the material carried on the first fixture 4. A second driving member 3 drives an extension frame 6 and a second fixture 5. The conveying directions of the first driving member 2 and the second driving member 3 are kept parallel, ensuring that the material transmission directions of the two sets of conveying mechanisms are consistent, facilitating docking with subsequent or preceding production and testing equipment. The first driving members 2 on both sides are positioned between the second driving members 3 on both sides, forming an inner-outer nested layout structure. The extension frame 6 extends from the second driving member 3 along the height and width directions of the frame 1 and crosses the first driving member 2, allowing the second fixture 5 to cross above or to the side of the first fixture 4, avoiding spatial interference with the first driving member 2 and the first fixture 4. The first driving component 2 and the second driving component 3 have the same structure and can be a linear motor or a cylinder. In some embodiments, the first driving component 2 and the second driving component 3 are driven by a servo motor to rotate a rotating shaft located on one side of the shaft. The two ends of the rotating shaft are respectively fixedly connected to a driving wheel. On the other side of the first driving component 2, two driven wheels corresponding to the driving wheels are respectively arranged. A belt is sleeved between the driving wheel and the driven wheel. A moving platform is fixed on one side of the belt. The first driving component 2 is provided with a sliding pair. The moving platform is movably connected to the main body of the first driving component 2 through the sliding pair and is driven by the belt to achieve movement.

[0040] The first conveying mechanism and the second conveying mechanism alternately perform loading and unloading tasks. When the first driving member 2 drives the first fixture 4 to move to the picking or unloading position, the second driving member 3 can drive the extension frame 6 and the second fixture 5 to move to another picking or unloading position, or to a standby state. When the first fixture 4 completes its current task and resets or moves to the next position, the second fixture 5 enters the working position to perform its task under the drive of the second driving member 3. Because the extension frame 6 crosses the first driving member 2, the movement path of the second fixture 5 and the movement path of the first fixture 4 are spatially misaligned, and they do not obstruct each other, thereby realizing continuous alternating loading and unloading operations.

[0041] Reference Figure 3As shown, the extension frame 6 includes a first extension 61 and a second extension 62. The first extension 61 is connected to the output end of the second drive member 3 and extends in the height direction of the frame 1. The length of the first extension 61 is greater than the thickness of the first fixture 4. The first extension 61 is connected to the output end of the second drive member 3, and its extension direction is along the front-back direction of the frame 1, that is, parallel to the vertical height dimension of the frame 1. The length of the first extension 61 is set to be greater than the thickness of the first fixture 4, where the thickness refers to the dimension of the first fixture 4 in the front-back direction of the frame 1. One end of the second extension 62 is fixedly connected to the first extension 61, and the other end extends in the left-right direction of the frame 1. It can extend from the first extension 61 in a direction away from or close to the center of the frame 1, providing a stable mounting position for the second fixture 5. When the second drive member 3 drives the extension frame 6 to move, the extension of the first extension 61 along the front-back direction of the frame 1 provides sufficient front-back space for the second fixture 5. Since the length of the first extension 61 is greater than the thickness of the first fixture 4, even if the first fixture 4 overlaps with the first extension 61 in the left-right direction along its movement path, the length of the first extension 61 in the front-back direction ensures that it will not collide with the first fixture 4. The extension of the second extension 62 in the left-right direction allows the second fixture 5 to cross the area where the first drive member 2 is located, ensuring that the installation position of the second fixture 5 meets the overall layout requirements, while providing stable support for the movement of the second fixture 5 and avoiding structural shaking caused by improper extension direction.

[0042] One end of the second extension 62 is connected to the first extension 61, and the other end extends along the width direction of the frame 1. The second extensions 62 on both sides extend towards each other. The two ends of the second fixture 5 are respectively connected to the second extensions 62 on both sides. The width of the second extension 62 is greater than the distance between the first drive member 2 and the second drive member 3. One end of the second extension 62 is fixedly connected to the first extension 61, and the other end extends along the left-right width direction of the frame 1. The second extensions 62 on both sides extend towards each other, that is, from both sides of the frame 1 towards the center, so that the second extensions 62 on both sides can converge in the middle area of ​​the frame 1, providing symmetrical connection points for the two ends of the second fixture 5. The two ends of the second fixture 5 are respectively fixedly connected to the second extensions 62 on both sides, realizing the stable installation of the second fixture 5. The width of the second extension 62 is set to be greater than the distance between the first drive member 2 and the second drive member 3. Here, the distance refers to the distance between the first drive member 2 and the second drive member 3 on the same side in the left-right direction of the frame 1.

[0043] The first and second conveying mechanisms are located on the first side of the frame 1. The installation positions of the first and second conveying mechanisms directly affect the overall layout of the device, space occupation, and efficiency of coordination with surrounding equipment. Considering the vertical placement of the frame 1, placing both mechanisms on the first side of the frame 1 achieves structural centralization, optimizes the operation process, reduces space waste, and facilitates integration with other production equipment, such as upstream feeding equipment.

[0044] like Figure 3 As shown, the component to be delivered 7 is glass or a display screen. The component to be delivered 7 is adsorbed by the suction cup assembly 44. The height of the first extension 61 is greater than the sum of the thickness of the component to be delivered 7 and the thickness of the second fixture 5, so that when the second fixture 5 adsorbs the component to be delivered 7, the first fixture 4 can pass through the space between the adsorption component of the second fixture 5 and the frame 1.

[0045] The first fixture 4 and the second fixture 5 have identical structures. The first fixture 4 is equipped with a suction cup assembly 44, with the suction end of the suction cup assembly 44 facing the second side of the frame 1. Combining the vertical placement of the frame 1 and the defined position of the second side, the stability and accuracy of material transfer are ensured by unifying the fixture structure and optimizing the suction cup orientation. Detailed description: The first fixture 4 and the second fixture 5 adopt completely identical structural designs, including the same frame structure, connection interfaces, load-bearing components, and auxiliary components. This structural consistency allows for the use of the same accessories and the execution of the same gripping actions, facilitating mass production, reducing design and manufacturing costs, and simplifying subsequent maintenance and replacement processes. The first fixture 4 is equipped with a suction cup assembly 44, which uses negative pressure adsorption to fix the material. Its suction end faces the second side of the frame 1, i.e., the side opposite to the first side. For example, if the first side of the frame 1 is the front, the second side is the back, ensuring that the suction end can accurately align with the area where the material is stored or to be placed.

[0046] Reference Figures 1-2 As shown, the plane containing the second side of the frame 1 forms an acute angle with the ground. The plane containing the second side of the frame 1 is not perpendicular to the ground, but rather forms an acute angle with it, meaning this side is inclined. Combined with the overall structure of the frame 1 being placed vertically, this inclined angle facilitates gripping by the suction cup assembly 44 and also facilitates subsequent inspection. The material placement area and docking equipment interface located on the second side are all situated on this inclined surface, creating a difference from a horizontal or vertical configuration.

[0047] The first fixture 4 includes: a base plate 41, a third driving member 42, and a movable frame 43. The two sides of the base plate 41 are connected to the first driving member 2. The third driving member 42 is mounted on the base plate 41. The movable frame 43 is connected to the output end of the third driving member 42 and moves along the height direction of the frame 1. The suction cup assembly 44 is connected to the movable frame 43.

[0048] By setting up a base plate 41, a third drive component 42, and a movable frame 43, the position of the suction cup assembly 44 in the front-to-back direction can be adjusted to adapt to different sizes, such as differences in thickness in the front-to-back direction or material gripping requirements at different front-to-back positions, thus improving the versatility of the device. Detailed description: The first fixture 4 includes a base plate 41, a third drive component 42, and a movable frame 43. The two sides of the base plate 41 are fixedly connected to the extension frame 6, serving as the mounting base for the entire first fixture 4 and providing stable support for the third drive component 42 and the movable frame 43, ensuring accurate installation of each component. The third drive component 42 is mounted on the base plate 41, and its output end is rigidly connected to the movable frame 43, driving the movable frame 43 to move in the front-to-back direction of the frame 1, that is, moving up and down parallel to the front-to-back dimension of the vertically placed frame 1. The suction cup assembly 44 is fixedly connected to the movable frame 43, and its front-to-back position changes synchronously with the movement of the movable frame 43, realizing the adjustment of the gripping height.

[0049] The movable frame 43 is positioned on the side of the base plate 41 facing the second side of the frame 1. The installation position of the movable frame 43 determines the relative distance between the suction cup assembly 44 and the material, as well as the space occupied by the movable frame 43 during movement. By combining the position of the second side of the frame 1 and the orientation of the suction cup assembly 44, positioning the movable frame 43 on the side of the base plate 41 facing the second side of the frame 1 optimizes the gripping path, shortens the distance between the suction cup assembly 44 and the material, improves operating efficiency, and simultaneously avoids interference between the movable frame 43 and components on the other side of the base plate 41 during movement.

[0050] Reference Figure 6 As shown, the third driving component 42 includes: a drive motor 421 mounted on the base plate 41; a drive screw 422 rotatably connected to the base plate 41 and connected to the output end of the drive motor 421; and a screw sleeve 423 connected to the movable frame 43 and adapted to the drive screw 422. The drive motor 421 provides power to the entire drive system by being fixedly mounted on the base plate 41. The rotation direction of its output shaft can be forward and reversed to realize the bidirectional forward and backward movement of the movable frame 43. The drive screw 422 is rotatably connected to the base plate 41 by bearings, and the bearing seat is fixed on the base plate 41 to ensure that the axis of the drive screw 422 is arranged along the forward and backward direction of the frame 1. One end of the drive screw 422 is connected to the output end of the drive motor 421. Specifically, a transmission belt can be fitted onto the first synchronous pulley fixed to the output shaft of the drive motor 421, and the transmission belt drives the second synchronous pulley to rotate. The second synchronous pulley and the drive screw 422 are coaxially fixedly connected, so that the drive screw 422 can rotate synchronously around its own axis under the drive of the drive motor 421. The screw sleeve 423 is fixedly connected to the movable frame 43 by bolts. Its interior is machined with an internal thread that matches the external thread of the drive screw 422. When the drive screw 422 rotates, the screw sleeve 423 can move linearly along the axial direction of the drive screw 422, that is, in the front-back direction of the frame 1, thereby driving the movable frame 43 to move synchronously in the front-back direction.

[0051] Reference Figure 7 As shown, the movable frame 43 is equipped with a guide sleeve 45, and the base plate 41 is equipped with a guide rod 46 that slides through the guide sleeve 45. The guide sleeve 45 is fixedly installed on the movable frame 43 by bolts. The guide sleeve 45 is a hollow tubular structure, and its axial direction is strictly arranged along the front-rear direction of the frame 1. The inner wall is precision machined to ensure smoothness and coaxiality. The guide rod 46 is fixedly installed on the base plate 41 at the position corresponding to the guide sleeve 45 by a bracket. The guide rod 46 is a cylindrical rigid rod made of high-strength metal, and its surface is quenched and ground to ensure hardness and smoothness. The axial direction of the guide rod 46 is consistent with the axial direction of the guide sleeve 45, and the outer diameter of the guide rod 46 is matched with the inner diameter of the guide sleeve 45 to form a clearance fit, ensuring that the guide sleeve 45 can slide smoothly along the axial direction of the guide rod 46. At the same time, the guide rod 46 strictly constrains the radial movement of the guide sleeve 45. Guide sleeves 45 and guide rods 46 are typically provided in two or more sets, symmetrically distributed on both sides of the movable frame 43 to ensure force balance. This is to accommodate first fixtures 4 and materials of different thicknesses, such as displays.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
