Description

Technical Field

[0001] This utility model relates to the field of trolley guidance and positioning, and in particular to a guidance and positioning mechanism. Background Technology

[0002] Previous AGV battery pack trolley guiding and positioning devices had low accuracy and reliability, failing to meet docking requirements. This device achieves precise positioning of the trolley and alignment with the AGV pallet positioning pins, enabling precise docking of the AGV with the laser welding room, improving battery pack welding quality and production efficiency. However, most existing devices are unidirectional guiding and positioning, resulting in low operational convenience and an inability to adapt to simultaneous guidance from both sides. Furthermore, the extensions of some bidirectional guiding mechanisms can take up considerable space, placing certain demands on the working environment.

[0003] Conventional positioning mechanisms may experience difficulties entering the positioning area or unstable positioning, and the wheels of the trolley may shift due to uneven force. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is that conventional positioning mechanisms have difficulty entering the positioning area or are unstable in positioning. The wheels of the trolley may be displaced due to uneven force. Furthermore, bidirectional guidance will occupy more space and have a certain impact on the surrounding environment.

[0005] The above-mentioned technical problems are solved by the following technical solution: This utility model proposes a guiding and positioning mechanism, which includes a guiding component, which includes two sets of guiding parts arranged symmetrically. The guiding component includes a guide rod, a limiting plate disposed on one side of the guide rod, and an extension rod disposed through the limiting plate. A positioning component is disposed on the side of the guide rod away from the extension rod, which includes a positioning disk. The positioning disk includes an entry section disposed at both ends and a positioning section between the two sets of entry sections along the direction of the extension rod. Both the entry section and the positioning section are inclined, and the slope of the positioning section is greater than the slope of the entry section.

[0006] In a preferred embodiment of the guiding and positioning mechanism of this utility model: two sets of guide rods are symmetrically arranged, and the two sets of guide rods are arranged on both sides of the positioning disk perpendicular to the direction of the extension rod, and the two ends of the two sets of guide rods extend away from the positioning disk.

[0007] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the guiding component further includes a base plate fixedly connected to the bottom of the guide rod, and a connecting hole is provided through the surface of the base plate. The base plate is fixed to the ground by bolts engaging with the connecting hole.

[0008] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the two sides of the positioning section of the positioning disk are fixedly connected to the base plate, the middle of the guide rod is horizontally set, and the two sets of positioning sections of the positioning disk are aligned with the endpoints of the horizontal part of the guide rod.

[0009] In a preferred embodiment of the guiding and positioning mechanism of this utility model: a connecting section is provided at the connection between the entry section and the positioning section of the positioning disk, and the connecting section is horizontally arranged.

[0010] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the limiting plate is provided with several sets, the limiting plate is provided with a sliding groove through it, the several sets of sliding grooves are horizontally aligned, and the extension rod slides in the several sets of sliding grooves.

[0011] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the circumferential sidewalls of the positioning segment are all arc-shaped.

[0012] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the bottom end of the positioning section is horizontally aligned with the entry section.

[0013] In a preferred embodiment of the guiding and positioning mechanism of this utility model: the positioning component further includes a gasket, which is fixedly connected to the horizontal section of the guide rod near the positioning disk.

[0014] In a preferred embodiment of the guiding and positioning mechanism of this utility model: threaded grooves are provided at both ends of the extension rod, and the threaded grooves on the extension rod are locked in conjunction with the nut.

[0015] The beneficial effects of this utility model are as follows: by allowing the extension rod to slide between the limiting plates, the adjustable single-sided extension rod can achieve bidirectional switching, which saves space while ensuring bidirectional guidance. By changing the slope between the entry section and the positioning section, the trolley wheels can enter the center of the positioning section more smoothly and achieve positioning more smoothly, avoiding the possibility of instability of the trolley after positioning.

[0022] To enable those skilled in the art to better understand this utility model, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0023] The terminology used in this invention refers to those general terms currently widely used in the art in consideration of the functionality of this invention; however, these terms may vary according to the intent, precedent, or new technology of those skilled in the art. Furthermore, specific terms may be chosen by the applicant, and in such cases, their detailed meanings will be described in the detailed description of this invention. Therefore, the terminology used in this specification should not be construed as simple names, but rather based on the meaning of the terms and the overall description of this invention.

[0024] Reference Figures 1-5 This embodiment provides a guiding and positioning mechanism, including a guiding assembly 1, which includes two symmetrically arranged guiding components 11. Each guiding component 11 includes a guide rod 111. The contact surface between the guide rod 111 and the wheel is arc-shaped, and the height of the guide rod 111 is designed to prevent the trolley from directly running over it. The specific height is determined based on the wheel height and is not specifically limited here. A limiting plate 112 is provided on one side of the guide rod 111. Both the limiting plate 112 and the guide rod 111 are fixedly connected to a base plate 12. The base plate 12 is fixed to the ground by expansion bolts passing through connecting holes 121. During the installation of plate 12, quality inspection is required to avoid loosening. The extension rod 113 is set through the limiting plate 112 and slides in the sliding groove 1121 of the limiting plate 112. During use, the position of the extension rod 113 can be adjusted according to the trolley's entry route. Specifically, it can be adjusted to extend to both sides of the limiting plate 112. It should be noted that the travel route of the conventional AGV trolley is defined before positioning. Therefore, the operator can adjust the extension direction of the extension rod 113 before the trolley travels through the defined route.

[0025] Positioning component 2, located on the side of guide rod 111 away from extension rod 113, includes positioning plate 21. Positioning plate 21 includes entry sections 211 at both ends and positioning section 212 between the two sets of entry sections 211 along the direction of extension rod 113. Both entry sections 211 and positioning section 212 are inclined. Note that the slope of entry section 211 should be gentle so that the trolley does not require more power to drive it during displacement. When the slope of entry section 211 is greater, the wheels of the trolley will move on the entry section 211. Sometimes, due to insufficient power and lack of sufficient fulcrum, the process of passing through the entry section 211 becomes more difficult, and deviations in the wheel travel path are more likely to occur. When the wheels are subjected to uneven forces, a certain force will be applied to the guide rod 111, which is more likely to cause deformation of the installation position of the guide rod 111. When this situation occurs repeatedly and the guide rod 111 is subjected to force, the service life of the guide rod 111 will be greatly shortened. In addition, the slope of the positioning section 212 is greater than that of the entry section 211, and the positioning section 212 forms a wheel positioning area around the center in a circumferential manner.

[0026] Furthermore, since the wheels of the trolley need to fall into the positioning area formed in the middle of the positioning section 212 after passing through the entry section 212, the wheels tend to slide down the positioning section 212. This can be achieved by increasing the slope of the positioning section 212 to make it greater than the slope of the entry section 212. Figure 5 As shown in the figure, the inclination angle between the entry section 212 and the ground is set as 'a', and the inclination angle between the positioning section 212 and the ground is set as 'b'. This ensures that the wheel will not wobble within the positioning section 212 due to inertia when it falls into the positioning section 212. During the wobble, the guide component 11 and the positioning plate 21 are prone to multiple impacts. Therefore, the inclination angle and the height of the highest point of the positioning section 212 can be determined first. When the inclination angle reaches a level that can limit the wheel to the positioning area in the middle of the entry section 212, it is directly limited within the positioning area and will not rise due to inertia impacting the other end of the positioning section 212. After determining the positioning section 212 and the highest point of the positioning section 212, the length of the entry section 212 is extended to make the extension section 212 more gentle, which is more stable during the rise and reduces the pressure on the guide component 11 and the positioning plate 21.

[0027] Furthermore, two sets of guide rods 111 are symmetrically arranged. These two sets of guide rods 111 are positioned on both sides of the positioning plate 21, perpendicular to the direction of the extension rod 113. The restriction provided by the two sets of guide rods 111 allows the wheels to move more horizontally, and both sides of the wheels are limited. When pushing the trolley, the operator only needs to focus on pushing forward. The ends of both sets of guide rods 111 extend away from the positioning plate 21, forming an open structure, thus allowing the wheels to be pushed without deliberately conforming to the extension rod 113. The extension rod 113 pushes the wheel. If the wheel is pushed by the extension rod 113, there may be some wear on the wheel and the extension rod 113 during the pushing process. Therefore, the extension rod 113 can be used to determine the general direction of the trolley's entry. When the trolley finally reaches the position of the guide rod 111, the guide rod 111 can guide the trolley into the horizontal section of the guide rod 111. Finally, under the guidance of the two sets of horizontal sections of the guide rod 111, the trolley reaches the center of the positioning section 212 through the entry section 211 of the positioning plate 21 to form a positioning.

[0028] Furthermore, the guide component 11 also includes a base plate 12 fixedly connected to the bottom of the guide rod 111. A connecting hole 121 is provided through the surface of the base plate 12. The base plate 12 is fixed to the ground by expansion bolts cooperating with the connecting hole 121 to prevent loosening.

[0029] Furthermore, the positioning segments 212 of the positioning disk 21 are fixedly connected to the base plate 12 on both sides. The integrated design can enhance the stability between the base plate 12 and the positioning disk 21. The guide rod 111 is horizontally set in the middle, and the two sets of positioning segments 212 of the positioning disk 21 are aligned with the end points of the horizontal part of the guide rod 111.

[0030] Furthermore, a connecting section 213 is provided at the connection between the entry section 211 and the positioning section 212 of the positioning disk 21. The connecting section 213 is horizontally set. The horizontal setting of the connecting section 213 can ensure that the wheel retains a certain impact force after passing through the slope of the entry section 211. It can slow down in the connecting section 213 and then fall into the positioning area in the center of the positioning section 212 through the slope of the positioning section 212.

[0031] Furthermore, the limiting plate 112 is provided with several sets, and the limiting plate 112 is provided with sliding grooves 1121. The several sets of sliding grooves 1121 are horizontally aligned. The extension rod 113 slides in the several sets of sliding grooves 1121, so that the extension rod 113 can only slide in the sliding grooves 1121. The inner ring of the sliding groove 1121 acts as a limiter for the extension rod 113 to prevent the extension rod 113 from shaking. The provision of multiple sets of limiting plates 112, and the provision of sliding grooves 1121 on each limiting plate 112, with the several sets of sliding grooves 1121 being horizontally aligned, together restrict the extension rod 113, which can enhance the stability of the extension rod 113. The circumferential sidewalls of the positioning section 212 are all arc-shaped, which can reduce the contact area with the wheel and prevent multiple points of contact with the wheel, thus preventing excessive wheel friction.

[0032] Furthermore, the bottom end of the positioning section 212 is horizontally aligned with the entry section 211. The positioning component 2 also includes a gasket 22, which is positioned at the bottom of the wheel to ensure more accurate contact with the wheel and greatly reduce wheel friction. The gasket 22 is fixedly connected to the horizontal section of the guide rod 111 near the positioning plate 21. Threaded grooves are provided on both ends of the extension rod 113. The threaded grooves on the extension rod 113 are locked with nuts. The cooperation between the nuts and the threaded grooves allows the extension rod 113 to be more stably fixed with the limiting plate 112.

[0033] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
