Description

Technical Field

[0001] This utility model relates to the technical field of turntable devices, and more particularly to a turntable mechanism. Background Technology

[0002] A turntable mechanism is a mechanical device that uses rotational motion to adjust the angle, position, and index a workpiece. It is commonly used in testing equipment and semiconductor processing equipment. With the continuous development of technology, turntable mechanisms have been widely adopted in various automated equipment.

[0003] Traditional turntable mechanisms typically employ worm gear transmission and rely on rigid bearings to ensure rotational accuracy. However, traditional standard turntable mechanisms still have several shortcomings. For instance, due to the significant weight of the bearings themselves, an additional bearing housing is often required during installation. By carefully controlling the fit between the bearing and the bearing housing during installation, stable rotation of the bearing is ensured. Therefore, traditional turntable mechanisms place certain requirements on the overall thickness, inner hole accuracy, and assembly process of the bearing housing. This results in excessive weight and high installation costs for the turntable mechanism.

[0004] In addition, if the traditional turntable mechanism is installed in automated equipment, it will further affect the overall cost performance of the equipment. Currently, there is still a lack of a turntable mechanism that can achieve portability and low cost in existing technology, so it needs to be improved.

[0005] The above information is provided as background information only to aid in understanding this disclosure and does not constitute an assertion or admission that any of the above content can be used as prior art relative to this disclosure. Utility Model Content

[0047] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0048] In the description of this utility model, it should be understood that when a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be a component that is centrally positioned therein. When a component is considered to be "set" on another component, it can be directly set on the other component or there may be a component that is centrally positioned therein.

[0049] Furthermore, terms such as "long," "short," "inner," and "outer" indicate orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings. They are used only for the convenience of describing this utility model and do not indicate or imply that the device or component referred to must have this specific orientation or operate in a specific orientational configuration. Therefore, they should not be construed as limitations of this utility model.

[0050] The following is in conjunction with the appendix Figure 1-5 The technical solution of this utility model will be further illustrated through specific implementation methods.

[0051] Please refer to Figure 1 and Figure 2This utility model embodiment provides a turntable mechanism, including an upper base plate 1, a limiting component 2, a turntable component 3, a guide component 4, and a drive component 5. In normal use, the turntable mechanism is horizontally set, and the following description is based on the turntable mechanism in normal use.

[0052] The upper base plate 1 has a flat plate structure and is set horizontally. The upper base plate 1 is used to provide installation positions for various components. By setting the upper base plate 1 on different types of equipment, the turntable mechanism can be installed, and the process is convenient and quick.

[0053] Meanwhile, the limiting component 2 is set on the upper base plate 1, and the turntable component 3 is set horizontally and used to place the product; based on this, the limiting component 2 and the turntable component 3 abut against each other, and the limiting component 2 applies a vertical movement limit to the turntable component 3, thereby restricting the turntable component 3 within a horizontal plane, so that the turntable component 3 and the upper base plate 1 are not easily separated from each other.

[0054] The guide component 4 is disposed on the upper base plate 1 and abuts against the periphery of the turntable component 3 to guide the turntable component 3 to rotate. With the combination of the guide component 4 and the limiting component 2, the turntable component 3 can rotate on the horizontal plane.

[0055] In addition, the drive assembly 5 is disposed on the upper base plate 1 and is connected to the turntable assembly 3. The drive assembly 5 is used to drive the turntable assembly 3 to rotate.

[0056] By adopting the above-mentioned configuration, the limiting component 2 provides limiting support for the turntable component 3, making it difficult for the turntable component 3 to loosen from the base plate 1. At the same time, under the guidance of the guide component 4, the turntable component 3 can rotate. The limiting component 2 and the guide component 4 replace the conventional bearing structure, which reduces the overall weight and cost of the turntable mechanism. Finally, driven by the drive component 5, the turntable mechanism can drive the product to rotate, and the product can realize functions such as angle adjustment, positioning, and indexing.

[0057] Reference Figure 3 In the embodiments of this application, the turntable assembly 3 includes a support column 31, an annular turntable 32, and a base 33. The annular turntable 32 is horizontally arranged and has a disc structure. The annular turntable 32 is used to abut against the limiting assembly 2 and to slide against the guide assembly 4.

[0058] The base 33 is also a disc structure. The base 33 is parallel to the annular turntable 32 and is connected to the drive assembly 5. The base 33 has a platform 331 for placing products. Specifically, the platform 331 is located in the middle of the base 33. Meanwhile, the support column 31 is located between the annular turntable 32 and the base 33 and is fixedly connected to the annular turntable 32 and the base 33 respectively.

[0059] Based on the above configuration, a turntable assembly 3 with a three-dimensional frame structure is obtained under the connection of the support column 31, which is lightweight. At the same time, the annular turntable 32, in cooperation with the limiting component 2 and the guide component 4, can play the role of bearing the rotational movement. Furthermore, by setting the platform part 331 on the base 33, the base 33 can bear the role of product placement. And by connecting the base 33 with the drive component 5, the base 33 can be driven to rotate, thereby driving the annular turntable 32 to rotate. Each component performs its own function, and interference and conflict are not likely to occur. The structural layout design is reasonable.

[0060] Furthermore, referring to Figure 2 and Figure 3 In the embodiments of this application, the annular turntable 32 is located below the upper base plate 1, and the base 33 is located below the annular turntable 32. At this time, the upper base plate 1 can hide the base 33 and the annular turntable 32 below, making the overall structure neater. On this basis, in order to enable the product to be smoothly placed on the platform part 331, the annular turntable 32 is provided with a first window 321 for exposing the platform part 331. Correspondingly, the upper base plate 1 has a second window 11 connected to the first window 321. Based on the above arrangement, the interconnected first window 321 and second window 11 can play a role in avoiding obstacles, thereby facilitating the picking and placing of products.

[0061] Furthermore, continue to refer to Figure 2 A protective cover 7 is provided at the inner edge of the second window 11. In this embodiment, a clearance hole is provided through the center of the protective cover 7. The protective cover 7 is fixed to the inner edge of the second window 11, and the clearance hole can expose the platform part 331. Based on the above configuration, the protective cover 7 can cover the gap between the turntable assembly 3 and the upper base plate 1, protect the rotating part, and prevent injury from the mechanism.

[0062] Furthermore, the turntable assembly 3 has hollow holes 6. Specifically, in this embodiment, the hollow holes 6 are respectively set on the base 33 and the annular turntable 32, thus obtaining a hollow three-dimensional frame structure. It can be understood that the hollow three-dimensional frame structure also has good structural strength. On this basis, the hollow design can save materials and reduce manufacturing costs on the one hand, and further reduce the structural weight on the other hand, making the structure lighter.

[0063] Reference Figure 4 In order to ensure that the turntable assembly 3 can be stably restricted on the horizontal plane, the limiting component 2 includes an upper roller 21 and a lower roller 22 disposed on the upper base plate 1, and the upper roller 21 and the lower roller 22 respectively abut against the opposite sides of the turntable assembly 3.

[0064] Specifically, in this embodiment, the limiting component 2 is located at the periphery of the turntable component 3. The bottom surface of the upper base plate 1 is provided with a mounting groove, and the upper roller 21 is installed in the mounting groove, with the ball bearing portion of the upper roller 21 protruding from the bottom surface of the upper base plate 1. In addition, an L-shaped bracket is fixedly provided on the bottom surface of the upper base plate 1, and the lower roller 22 is installed on the L-shaped bracket. The L-shaped bracket extends the lower roller 22 to below the upper roller 21, and the lower roller 22 and the upper roller 21 are arranged opposite to each other. At this time, the annular turntable 32 in the turntable component 3 is embedded between the upper roller 21 and the lower roller 22, and the opposite sides of the annular turntable 32 in the turntable component 3 roll and abut against the upper roller 21 and the lower roller 22 respectively.

[0065] Based on the above configuration, the upper roller 21 and the lower roller 22 provide upper and lower clamping forces to the annular turntable 32 to achieve a limiting effect. On the other hand, the upper roller 21 and the lower roller 22 can provide rolling friction, making the turntable assembly 3 rotate more smoothly and less prone to jamming.

[0066] Optionally, multiple sets of limiting components 2 can be set, such as two, three, or four sets. Multiple sets of limiting components 2 are evenly arranged along the circumferential direction of the turntable component 3, thereby providing multi-point limiting for the turntable component 3 and optimizing and improving the limiting effect. It is understood that the specific number of limiting components 2 can be adjusted according to actual needs, and no specific restrictions are made here. In this embodiment, four sets of limiting components 2 are set as an example.

[0067] Reference Figure 3 To ensure that the turntable assembly 3 can rotate smoothly, the guide assembly 4 includes several limiting cams 41. The turntable assembly 3 has a circumferential edge, and the limiting cams 41 are rotatably mounted on the upper base plate 1 and roll against the circumferential edge.

[0068] Specifically, in the embodiments of this application, the circumferential edge of the turntable assembly 3 corresponds to the periphery of the annular turntable 32, and the limiting cam 41 abuts against the annular turntable 32. Optionally, the specific number of limiting cams 41 can be two, four, or six, etc., with several limiting cams 41 evenly distributed around the turntable assembly 3. The specific number of limiting cams 41 can be adjusted according to actual needs, and no specific limitation is made here. In this embodiment, there are four limiting cams 41, which are distributed around the annular turntable 32. Thus, under the rolling guidance of several limiting cams 41, the turntable assembly 3 can rotate smoothly.

[0069] Furthermore, there may be assembly errors during the installation of the limiting cam 41. If the error is too large, it may lead to insufficient guiding effect and wobbling of the turntable assembly 3 during rotation. Based on this, the upper base plate 1 is adjustablely provided with a fine-tuning connecting seat 42. The limiting cam 41 is set on the fine-tuning connecting seat 42. The fine-tuning connecting seat 42 can be moved by adjustment, thereby controlling the distance between the limiting cam 41 and the turntable assembly 3, so that the limiting cam 41 can be tightly matched with the turntable assembly 3.

[0070] Specifically, in one embodiment, in order to realize the fine adjustment function of the fine adjustment connector 42, an oblong hole can be opened on the fine adjustment connector 42, and then a bolt is inserted into the oblong hole and threaded onto the upper base plate 1. The oblong hole provides adjustment space. By controlling the tightness of the bolt, the stopping position of the fine adjustment connector 42 can be changed, thereby controlling the distance between the limit cam 41 and the turntable assembly 3.

[0071] Furthermore, referring to Figure 5 To drive the turntable assembly 3 to rotate smoothly, the drive assembly 5 includes a motor 51, a drive synchronous pulley 52, a synchronous belt 53, and a tension pulley 54. The upper base plate 1 has mounting holes, and the motor 51 is fixedly mounted on the upper base plate 1, with its output shaft extending through the mounting holes to the side where the turntable assembly 3 is located.

[0072] The active synchronizing pulley 52 is connected to the output shaft of the motor 51. Typically, the active synchronizing pulley 52 is fixedly mounted on the output shaft of the motor 51. In this case, the motor 51 can drive the active synchronizing pulley 52 to rotate. In addition, the synchronous belt 53 is wrapped around the active synchronizing pulley 52 and the turntable assembly 3. Specifically, since the base 33 in this embodiment is a disc structure, the periphery of the base 33 can be wrapped around the synchronous belt 53. By wrapping the synchronous belt 53 around the periphery of the base 33 and the active synchronizing pulley 52, the synchronous belt 53 can be driven to rotate during the rotation of the active synchronizing pulley 52, thereby enabling the base 33 to rotate.

[0073] It should be explained that in a standard turntable mechanism, a large-diameter synchronous pulley is usually required to drive the base 33 to rotate. This solution connects the base 33 directly to the synchronous belt 53, which is equivalent to eliminating the need for the large-diameter synchronous pulley, thus saving weight and reducing costs.

[0074] In addition, the tensioning pulley 54 is rotatably mounted on the upper base plate 1, and abuts against the synchronous belt 53 to tension the synchronous belt 53. Through the above arrangement, the tensioning pulley 54 tensions the synchronous belt 53, so that the synchronous belt 53 can tightly wrap around the base 33 and the drive synchronous pulley 52, making the synchronous belt 53 less prone to slippage and the transmission more stable.

[0075] Specifically, the tensioning wheel 54 is adjustablely mounted on the upper base plate 1. It also includes an adjusting seat 55, on which the tensioning wheel 54 is rotatably mounted, and the adjusting seat 55 has a slotted hole. Simultaneously, the upper base plate 1 has a threaded hole, through which a bolt can be threaded. The slotted hole allows the adjusting seat 55 to have displacement adjustment space. By controlling the tightness of the bolt, the adjusting seat 55 can move and adjust along the length of the slotted hole. During the adjustment of the adjusting seat 55, the distance between the tensioning wheel 54 and the timing belt 53 can be adjusted, thereby controlling the tension of the timing belt 53, facilitating installation and debugging.

[0076] Furthermore, the turntable assembly 3 is provided with synchronous gear teeth 34, which mesh with the synchronous belt 53. Specifically, an insert groove 341 is provided at the periphery of the base 33, and the synchronous gear teeth 34 are fitted into the insert groove 341. The meshing teeth on the synchronous gear teeth 34 extend out of the periphery of the base 33. The synchronous gear teeth 34 mesh with the synchronous belt 53 through the meshing teeth. The synchronous gear teeth 34 can increase the friction between the synchronous belt 53 and the synchronous belt 53, making the structure less prone to slippage.

[0077] Optionally, the number of synchronous gear teeth 34 can be set to multiple, and the number of insert slots 341 should also be adapted accordingly. Specifically, two, three, or four slots can be set. In this embodiment, four slots are set as an example. The specific number of synchronous gear teeth 34 can be adjusted according to actual needs, and no specific limitation is made here. On this basis, multiple synchronous gear teeth 34 are arranged at intervals around the base 33, which can play a multi-point anti-slip effect, further reducing the probability of the synchronous belt 53 slipping and further optimizing and improving the transmission stability.

[0078] The turntable mechanism provided in this application has the following beneficial effects:

[0079] 1. Under the action of the limiting component 2 and the guiding component 4, the annular turntable 32 replaces the large-size bearing structure on the standard turntable mechanism, which reduces the weight of the turntable mechanism and effectively reduces the setting cost of the structure.

[0080] 2. By directly wrapping the synchronous belt 53 around the base 33, the large-diameter synchronous pulley on the standard turntable mechanism can be replaced, thereby reducing the overall weight of the mechanism and the installation cost.

[0081] 3. The protective cover 7 can effectively isolate the rotating parts, making the structure safe and reliable.

[0082] Therefore, the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
