Description

Technical Field

[0001] This application relates to the technical field of conveying equipment, and in particular to a positioning mechanism and conveying system. Background Technology

[0002] With the continuous advancement of technology, the use of automated conveying equipment to transport materials to various processing stations has become a common production method in many industries, thereby improving production efficiency and saving labor costs. During operation, the conveying equipment moves at high speed along the production line. Positioning mechanisms are installed on the line; when the conveying equipment carrying materials arrives at the designated station, the controller sends a command to the positioning mechanism, which then positions the conveying equipment.

[0003] However, the current positioning mechanism for positioning conveying equipment in the X direction mainly uses the blocking and stopping method. That is, the block is driven by a cylinder or electric actuator to extend and block the conveying equipment to stop it. However, because the conveying equipment moves at a high speed, the impact force of the conveying equipment on the block is large. After the block is hit by the conveying equipment frequently and repeatedly, it is easy to bend and deform, which leads to a decrease in positioning accuracy. This causes the conveying equipment to be unable to accurately deliver the material to the designated work station, affecting normal processing. Utility Model Content

[0004] Therefore, it is necessary to provide a positioning mechanism and conveying system to address the problem that deformation leads to reduced positioning accuracy and affects normal processing.

[0005] A first aspect of this application provides a positioning mechanism, comprising:

[0006] The mounting base has guide sliding holes that extend through both ends;

[0007] A positioning driver, wherein the positioning driver is disposed on the mounting base;

[0008] A positioning stop shaft, wherein the two ends of the positioning stop shaft along its length are respectively designated as a connecting end and a positioning end, the connecting end being connected to the telescopic shaft of the positioning driver, and the positioning stop shaft being movably inserted into the guide sliding hole; and

[0009] A mating block is used to be installed on a conveyor trolley. The mating block has a mating hole. When the positioning driver drives the positioning stop shaft to extend, the positioning end can be inserted into the mating hole.

[0010] The positioning mechanism in this solution is applied to the conveying system, specifically for X-axis positioning of the material conveying trolley to ensure it accurately stops at the designated workstation. In practice, the mounting base is fixed to the conveyor bed, and the mating block is fixed to the conveying trolley. Initially, the telescopic shaft of the positioning driver keeps the positioning stop shaft in the retracted position. When the conveying trolley carrying material arrives at the designated workstation, under control, the positioning driver immediately drives the telescopic shaft to extend, and the positioning stop shaft extends synchronously under the drive of the telescopic shaft, allowing the positioning end to accurately insert into the mating block. The positioning stop shaft physically blocks the conveyor trolley within the designated workstation by fitting the hole. Since the middle part of the positioning stop shaft passes through the guide slide hole and the positioning end is simultaneously inserted into the fitting hole, it is supported and reinforced by both the fitting block and the mounting base, thus enhancing the strength of the positioning stop shaft. This ensures that the positioning stop shaft is not easily bent or deformed even when frequently subjected to the impact force of the conveyor trolley, guaranteeing the positioning accuracy of the positioning mechanism for the conveyor trolley and solving the problem of the conveyor trolley failing to accurately deliver materials to the designated workstation, thus affecting normal processing.

[0011] The technical solution of this application will be further described below:

[0012] In one embodiment, the end wall of the mating hole facing the positioning stop shaft is provided with an inlet slope, which is used to make it easier for the positioning end to be inserted into the mating hole.

[0014] In one embodiment, the diameter of the mating hole is less than or equal to the diameter of the positioning stop wheel.

[0015] In one embodiment, the positioning mechanism further includes a bushing fitted into the guide slide hole, and the positioning stop shaft is movably inserted through the bushing.

[0016] In one embodiment, the positioning mechanism further includes an anti-rotation component, which is disposed on the mounting base and engages with the positioning stop shaft to prevent rotation.

[0017] In one embodiment, the anti-rotation assembly includes a mounting member and an anti-rotation pressure plate. The positioning stop shaft has an anti-rotation plane facing the anti-rotation pressure plate. The anti-rotation pressure plate is disposed on the mounting base through the mounting member, and the anti-rotation pressure plate is press-fitted with the anti-rotation plane.

[0018] In one embodiment, the anti-rotation assembly includes a fastener and an anti-rotation pin, the positioning stop shaft has an anti-rotation hole facing the anti-rotation pin, the anti-rotation pin is fixed to the mounting base by the fastener, and the end of the anti-rotation pin is inserted into the anti-rotation hole.

[0019] In one embodiment, the mounting base includes a mounting plate and a support base, the mounting plate being mounted on a conveyor bed, the support base being mounted on the mounting plate, and the support base being provided with the guide sliding hole;

[0020] The support base is also provided with a notch, the main body of the positioning driver is located on the top of the support base, and the telescopic shaft of the positioning driver passes through the notch.

[0035] Please see Figures 1 to 3 The present application shows a positioning mechanism 100, which includes a mounting base 10, a positioning driver 20, a positioning stop shaft 30, and a mating block 40.

[0036] The mounting base 10 has guide sliding holes 121 extending through both ends. During actual installation, the positioning mechanism 100 is mounted on the side of the conveyor bed 200, while the conveyor trolley moves on the upper surface of the conveyor bed 200; therefore, the positioning mechanism 100 is located below the conveyor trolley. Thus, to ensure that the positioning mechanism 100 can position the conveyor trolley in the X-axis, the guide sliding holes 121 must be arranged in a vertically extending manner.

[0037] The positioning actuator 20 is mounted on the mounting base 10. Optionally, the positioning actuator 20 may be any one of, but not limited to, a cylinder, an electric actuator, or a hydraulic cylinder.

[0038] Please continue reading. Figure 1 and Figure 2 The two ends of the positioning stop shaft 30 along its length are respectively designated as a connecting end 31 and a positioning end 32. The connecting end 31 is connected to the telescopic shaft of the positioning driver 20, and the positioning stop shaft 30 is movably inserted into the guide sliding hole 121. That is, under the power drive of the positioning driver 20, the positioning stop shaft 30 moves up and down in the vertical direction, or in other words, the positioning stop shaft 30 moves telescopically relative to the mounting base 10.

[0039] The mating block 40 is used for installation on the conveyor trolley. The installation method can be at least one of the following: screw connection, snap connection, adhesive connection, riveting, etc., whichever is required.

[0040] The mating block 40 has a mating hole 41. When the positioning driver 20 drives the positioning stop shaft 30 to extend, the positioning end 32 can be inserted into the mating hole 41.

[0041] In summary, implementing the technical solution of this embodiment will achieve the following technical effects: The positioning mechanism 100 of this solution is applied to the conveying system, specifically for X-axis positioning of the conveying trolley carrying materials, to ensure that the conveying trolley can accurately stop at the designated workstation; specifically, in use, the mounting base 10 is fixed to the conveying bed 200, and the mating block 40 is fixed to the conveying trolley. In the initial state, the telescopic shaft of the positioning driver 20 drives the positioning stop shaft 30 to remain in the retracted position; when the conveying trolley carrying materials arrives at the designated workstation, under the control of the command, the positioning driver 20 immediately drives the telescopic shaft to extend, and the positioning stop shaft 30 extends synchronously under the drive of the telescopic shaft, so that the positioning end 32 The positioning block 30 is accurately inserted into the mating hole 41 of the mating block 40, thereby stopping the conveyor trolley in the designated work position by the physical blocking of the positioning stop shaft 30. Since the middle part of the positioning stop shaft 30 passes through the guide sliding hole 121 and the positioning end 32 is simultaneously inserted into the mating hole 41, it can be supported and reinforced by both the mating block 40 and the mounting base 10, which enhances the strength of the positioning stop shaft 30. This ensures that the positioning stop shaft 30 is not easily bent or deformed even if it is frequently subjected to the impact force of the conveyor trolley, thus ensuring that the positioning accuracy of the positioning mechanism 100 for the conveyor trolley is reduced and solving the problem that the conveyor trolley cannot accurately deliver the material to the designated work position, affecting normal processing.

[0042] Based on the above embodiment, the end wall of the mating hole 41 facing the positioning stop shaft 30 is provided with an inlet slope, which is used to make it easier for the positioning end 32 to be inserted into the mating hole 41.

[0043] Depending on the actual needs, the guide slope can be set only in a part of the end wall of the orifice of the annular structure, or it can be arranged around the entire end wall of the orifice of the annular structure. By setting the guide slope, the orifice of the mating hole 41 facing the positioning stop shaft 30 can be formed into a flared structure, so that even if there is a misalignment, the positioning end 32 can be quickly and effectively inserted into the mating hole 41.

[0044] In another embodiment, the positioning mechanism 100 further includes a positioning stop wheel 50, which is rotatably disposed on the positioning end 32. By providing a freely rolling positioning stop wheel 50, the positioning stop wheel 50 will rotate on its own due to friction during the insertion of the positioning end 32 into the mating hole 41, thereby making it easier and faster for the positioning end 32 to be inserted into the mating hole 41.

[0045] Optionally, the positioning wheel 50 is made of rubber. The rubber wheel has a certain elasticity, which can reduce the instantaneous impact force when it comes into contact with the mating block 40, and prevent collision noise and damage to the mating block 40.

[0046] Furthermore, the diameter of the mating hole 41 is less than or equal to the diameter of the positioning wheel 50. Preferably, the diameter of the mating hole 41 is slightly smaller than the diameter of the positioning wheel 50. For example, if the diameter of the positioning wheel 50 is 8cm, the corresponding diameter of the mating hole 41 is 7.5cm-7.8cm. This ensures that the positioning wheel 50 can be smoothly inserted into the mating hole 41, and that after insertion, the positioning wheel 50 and the wall of the mating hole 41 are in a tight fit relationship with no gap, thus preventing the conveyor trolley from easily shifting.

[0047] Please continue reading. Figure 1 In another embodiment, the positioning mechanism 100 further includes a bushing 60, which is fitted into the guide slide hole 121, and the positioning stop shaft 30 is movably inserted into the bushing 60. On the one hand, the bushing 60, as an intermediate stop, can prevent the positioning stop shaft 30 from rubbing and wearing against the guide slide hole 121 during telescopic sliding, and can improve the smoothness of movement of the positioning stop shaft 30, preventing problems such as jamming; on the other hand, under the guiding action of the bushing 60, the extension direction of the positioning stop shaft 30 is more stable, which helps to ensure that the positioning end 32 is accurately inserted into the mating hole 41.

[0048] Furthermore, based on any of the above embodiments, the positioning mechanism 100 also includes an anti-rotation component 70, which is disposed on the mounting base 10 and engages with the positioning stop shaft 30 to prevent rotation. The anti-rotation component 70 is used to limit the positioning stop shaft 30 from rotating about its own axis, so as to ensure that the positioning stop wheel 50 can be inserted into the mating hole 41 in the correct direction.

[0049] Please continue reading. Figure 1 Specifically, in an optional embodiment, the anti-rotation assembly 70 includes a mounting member 71 and an anti-rotation pressure plate 72. The positioning stop shaft 30 is provided with an anti-rotation plane 33 facing the anti-rotation pressure plate 72. The anti-rotation pressure plate 72 is mounted on the mounting base 10 through the mounting member 71, and the anti-rotation pressure plate 72 is pressed into contact with the anti-rotation plane 33.

[0050] Alternatively, as an alternative to the above embodiments, in another optional embodiment, the anti-rotation component 70 includes a fastener and an anti-rotation pin. The positioning stop shaft 30 is provided with an anti-rotation insertion hole facing the anti-rotation pin. The anti-rotation pin is fixed to the mounting base 10 by the fastener, and the end of the anti-rotation pin is inserted into the anti-rotation insertion hole.

[0051] Both of the above embodiments can restrict the rotational freedom of the positioning stop shaft 30 by pressing it, thereby preventing the positioning stop shaft 30 from rotating out of place.

[0052] In one embodiment, the mounting base 10 includes a mounting plate 11 and a support base 12. The mounting plate 11 is used to mount on the conveyor bed 200. For example, the mounting plate 11 is rectangular, with through holes at each of the four corners. The conveyor bed 200 has four corresponding threaded holes. Bolts are passed through the through holes and screwed into the threaded holes to complete the connection and fixation between the mounting plate 11 and the conveyor bed 200, thus achieving the assembly of the mounting base 10 and the conveyor bed 200.

[0053] Please continue reading. Figure 1 The support base 12 is mounted on the mounting plate 11 and has a guide sliding hole 121. The support base 12 also has a notch 122. The main body of the positioning driver 20 is located on the top of the support base 12, and the telescopic shaft of the positioning driver 20 passes through the notch 122. This arrangement allows the positioning driver 20 and the mounting base 10 to be longitudinally arranged, making full use of the vertical space, reducing the lateral space occupation, facilitating the installation and arrangement of the positioning mechanism 100, and making it suitable for installation in confined spaces.

[0054] In addition to the above, this application also provides a conveying system, which includes the positioning mechanism 100 as described in any of the above embodiments.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
