Description

Technical Field

[0001] The utility model relates to the technical field of positioning mechanisms, in particular to a logistics warehouse positioning mechanism. Background Art

[0002] Magnetic steel is generally manufactured by powder metallurgy, and in order to improve production efficiency, it is usually first processed into long magnetic strips during the manufacturing process, and then the magnetic strips are cut and segmented according to the actual required length. The segmented magnets also need to undergo multiple processing steps, such as rough grinding, semi-fine grinding, and fine grinding, and each step needs to be processed by dedicated equipment.

[0003] At present, after one process is completed, the workpiece is usually placed on a transfer tray. When the transfer tray is full, it is manually moved to the next process. That is, the workpiece needs to be transported manually or manually by a transport cart during the entire assembly line processing. Either method requires a lot of human resources, which is not only time-consuming and labor-intensive, but also affects the efficiency of the entire product assembly line processing.

[0004] The applicant has developed a mobile transit warehouse, also known as a logistics warehouse. The structure of the logistics warehouse has been patented. The logistics warehouse can automatically transfer workpieces between different workstations, reduce labor costs, and improve work efficiency. However, after the introduction of the logistics warehouse, how to fix it with the rack of each workstation has become a new problem. At present, it is generally connected and positioned manually using a buckle structure. This positioning method is inconvenient to operate and occupies too much labor resources, resulting in increased labor costs. In addition, the degree of automation is low, which is not conducive to the development of intelligent workshops. Utility Model Content

[0007] Compared with the prior art, the utility model has the following advantages:

[0008] The logistics warehouse positioning mechanism of the utility model is through two scissor-type clamping arms, and positioning arms are respectively arranged at the outer ends of the two clamping arms, so that a positioning channel for the positioning end of the logistics warehouse to enter is formed between the two positioning arms, so as to ensure the positioning direction; and guide plates are arranged on the two positioning arms, when the positioning end of the logistics warehouse enters the positioning channel, the driving mechanism drives the two clamping arms to move together, and under the action of the two guide plates, the rollers on both sides of the positioning end slowly move toward one side of the frame, because the bottom of the logistics warehouse has its own wheels, so when the two rollers move, they can move the entire logistics warehouse toward one end of the frame until they reach the preset position for limiting, and the entire moving limiting process does not require manual participation, has a high degree of automation, and can save labor costs.

[0009] Furthermore, the driving mechanism includes a slide plate, two linkage arms and a driving assembly. A vertically extending mounting pin is provided at one end of the mounting base plate near the logistics warehouse. The two clamping arms are cross-hinged on the mounting pin. The slide plate is slidably connected to the other end of the mounting base plate. The driving assembly is used to drive the slide plate to slide along the positioning movement direction of the logistics warehouse. One end of the two linkage arms is hinged to the slide plate, and the other end is respectively hinged to one end of the two clamping arms away from the positioning arm. The above structure is operated by forming a connecting rod mechanism through two linkage arms, the slide plate and the two clamping arms. The linear movement of the slide plate is converted into the rotation of the two clamping arms, which simplifies the structure of the driving assembly and reduces the cost.

[0010] Furthermore, the driving assembly includes a motor, a screw and a screw slider, the screw is rotatably connected to the mounting base along its own axis, the screw slider is fitted outside the screw, the motor is used to drive the screw to rotate, and the slide is connected to the screw slider.

[0022] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0023] In the description of the present invention, it should be noted that the directions or positional relationships indicated by the terms "front and back", "left and right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the term "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] like Figure 1 , 2 As shown, the utility model provides a logistics warehouse positioning mechanism, which is installed on a rack 1 and is used to clamp and position the logistics warehouse. The logistics warehouse here is mainly used for temporary storage of transfer workpieces, and it is a mobile storage warehouse to realize the flow of workpieces between different workstations. That is, when the logistics warehouse and the rack 1 of the corresponding process are positioned stably, it is used to realize the transfer of the workpieces that have completed the corresponding process on the rack 1 to the logistics warehouse, or to transfer the workpieces in the logistics warehouse to the rack 1 for the corresponding operation process.

[0026] The logistics warehouse positioning mechanism includes a mounting base plate 2, which is used to be connected and fixed to a frame 1 of a corresponding operating process. The mounting base plate 2 is provided with two clamping arms 3 in a scissor-type structure at one end away from the frame 1, and a driving mechanism for driving the two clamping arms 3 to move closer to and separate from each other in the left and right directions, and the two clamping arms 3 are provided with a positioning arm 4 at one end away from the driving mechanism, and a positioning channel 5 is formed between the two positioning arms 4. In this embodiment, each positioning arm 4 is respectively arranged at an obtuse angle to the corresponding clamping arm 3, and the two positioning arms 4 are parallel in the initial stage, so that the logistics warehouse can better enter the positioning channel 5. Figure 2 In addition, the ends of the two positioning arms 4 away from the clamping arms 3 are both provided with guide plates 6. When the positioning end 19 of the logistics warehouse enters the positioning channel 5, the driving mechanism is used to drive the two clamping arms 3 to move together, and the two guide plates 6 are used to drive the rollers on both sides of the positioning end 19 to move the entire logistics warehouse toward one end of the rack 1 to a set position and position it.

[0027] Specifically, in this embodiment, the driving mechanism includes a slide plate 7, two linkage arms 8 and a driving assembly. A vertically extending mounting pin 9 is provided at one end of the mounting base plate 2 close to the logistics warehouse. The two clamping arms 3 are cross-hinged on the mounting pin 9 to form a scissor-like structure. By operating the two ends of the two clamping arms 3 away from the logistics warehouse to move together or apart, the two clamping arms 3 can clamp the logistics warehouse or release the clamping and positioning of the logistics warehouse. The structure is simple and easy to operate. In addition, in this structure, the slide plate 7 is slidably connected to the other end of the mounting base plate 2, and the driving assembly is used to drive the slide plate 7 to slide along the positioning movement direction of the logistics warehouse. One end of the two linkage arms 8 is hinged to the slide plate 7, and the other end is respectively hinged to one end of the two clamping arms 3 away from the positioning arm 4. Specifically, the hinged position of the two linkage arms 8 and the two clamping arms 3 is movable, and they are only rotatably connected through the corresponding hinge shafts. There are no other constraints, that is, the mounting pin 9 in this structure is fixed and the two hinge shafts are movable.

[0028] In addition, one end of the installation base plate 2 close to the logistics warehouse is defined as the front end, and the other end is defined as the rear end. It should be noted that the front and rear here are only for the convenience of understanding this scheme, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present utility model.

[0029] Therefore, in the above structure, when the movable plate moves toward the rear end of the mounting base plate 2, the two linkage plates move closer to each other, thereby driving the rear ends of the two clamping arms 3 to move closer to each other, and finally making the front ends of the two clamping arms 3 retract inward, and under the action of the two corresponding guide plates 6, the logistics warehouse is driven to move toward one end of the frame 1 until the rear end of the logistics warehouse is against the front end of the frame 1; and at this time, the two guide plates 6 are still limited on the outside of the two rollers to realize the positioning of the logistics warehouse and the frame 1; similarly, when the logistics warehouse needs to be separated from the frame 1, it is only necessary to drive the movable plate toward the front end of the mounting base plate 2. The driving principle is similar to the above and will not be described in detail.

[0030] More specifically, in this embodiment, Figure 1 As shown, the drive assembly includes a motor 10, a screw rod 11 and a screw rod slider 12. The screw rod 11 is rotatably connected to the mounting base plate 2 along its own axis, and the screw rod slider 12 is matched with the outside of the screw rod 11. The motor 10 is used to drive the screw rod 11 to rotate. The slide plate 7 is connected to the screw rod slider 12. The forward and reverse rotation of the motor 10 drives the screw rod 11 to rotate in the forward and reverse directions, thereby driving the screw rod slider 12 to move forward or backward along the axial direction of the screw rod 11, and finally realizes the approach and expansion of the two clamping arms 3; the screw rod 11 structure is driven smoothly and reliably, and the moving distance is accurately controllable; in this structure, the power output end of the motor 10 is connected to a deceleration component to ensure that the driving force is stably output to the screw rod 11. In other embodiments, the drive assembly can also directly use one of the cylinders, oil cylinders or electric push cylinders.

[0031] In addition, in order to further ensure the stability of the movement of the slide plate 7, as Figure 2 As shown, two linear guide rails 13 are provided on the mounting base plate 2 and are located on both sides of the screw rod 11. The two ends of the slide plate 7 are respectively connected to the sliders 14 of the two linear guide rails 13. After the linear guide rails 13 are provided, the stability and linearity of the movement process of the slide plate 7 are effectively guaranteed, thereby improving the stability of the clamping action of the two clamping arms 3.

[0032] In the above structure, the two guide plates 6 are used to realize the mobile positioning of the logistics warehouse. Specifically, the two guide plates 6 are arranged to be tilted from outside to inside along the opening direction of the positioning channel 5 (from back to front), and the tilt angle of the two guide plates 6 is adjustable. Figure 3 , 4As shown, when the logistics warehouse moves toward the frame 1 until the rollers on both sides of its positioning end 19 enter the positioning channel 5, the two guide plates 6 are located on the outside of the two rollers. As the driving component moves, the front ends of the two clamping arms 3 are driven to move closer to each other. Under the action of the guide slopes of the two guide plates 6, the rollers rotate and continue to move toward one side of the frame 1 during the rolling process until the end face of the positioning end 19 abuts against the front end setting position of the frame 1 and no longer moves. At this time, the two guide plates 6 are always tightly clamped and limited on the outside of the two rollers to achieve the positioning of the logistics warehouse.

[0033] In the above structure, if Figure 5 , 6 As shown, the two guide plates 6 have the same structure, and both include a vertical baffle 6.1 and a horizontal mounting plate 6.2 which are perpendicular to each other, wherein the horizontal mounting plate 6.2 is horizontally fitted on the upper surface of the positioning arm 4; specifically, waist-shaped holes are provided at both ends of the horizontal mounting plate 6.2, and the length direction of the waist-shaped holes is perpendicular to the vertical baffle 6.1, and each waist-shaped hole is penetrated with a connecting screw for connecting to the positioning arm 4. In this embodiment, more specifically, two waist-shaped holes are defined as a first waist-shaped hole 15 and a second waist-shaped hole 16 along the front-back direction, a first connecting hole 17 is provided on the positioning arm 4 corresponding to the first waist-shaped hole 15, and a plurality of second connecting holes 18 are provided at positions corresponding to the second waist-shaped holes 16, and the plurality of second connecting holes 18 are distributed along an arc, and the center of the arc coincides with the center of the first connecting hole 17. The inclination angle of the guide plate 6 can be adjusted by adjusting the connecting screws to connect to different second connecting holes 18, so as to better ensure the limit cooperation between the object guide plate 6 and the corresponding rollers in the logistics warehouse, and the accurate connection position of the logistics warehouse and the rack 1 after positioning, which is conducive to the workpieces in the logistics warehouse to be accurately clamped and moved to the corresponding operating stations on the rack 1 by the manipulator.

[0034] Although the utility model is disclosed as above, the protection scope of the utility model is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the utility model, and these changes and modifications will fall within the protection scope of the utility model.
