Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0057] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0058] like Figure 1 and Figure 2 As shown in the embodiment of this application, a barbell plate unloading device is proposed, comprising: a first moving component 11, a lifting component 12, a second moving component 13, and a clamping component 14; the first moving component 11 includes a first moving seat 111, which is movable along the length direction of the first moving component 11; the lifting component 12 is disposed on the first moving seat 111, and the first moving seat 111 drives the lifting component 12 to move along the length direction of the first moving component 11; the second moving component 13 is disposed perpendicular to the first moving component 11; the second moving component 13 includes a second moving seat 131, which is movable along the length direction of the second moving component 13; the clamping component 14 is disposed on the second moving seat 131, and the second moving seat 131 drives the clamping component 14 to move along the length direction perpendicular to the first moving component 11.

[0059] The barbell plate removal device provided in this embodiment includes a first moving component 11, a lifting component 12, a second moving component 13, and a clamping component 14. The first moving component 11 moves the lifting component 12 via a first moving base 111, and the second moving component 13 moves the clamping component 14 via a second moving base 131. When it is necessary to remove the barbell plates 17 from the barbell, the barbell is first placed on the ground. The first moving component moves the lifting component 12 to below the barbell bar 16, and the lifting component 12 lifts the barbell. The first moving base 111 then lifts the lifting component 14. The barbell 12 and barbell bar 16 are moved to the vicinity of the clamping assembly 14, and the height of the barbell is adjusted by the lifting assembly 12 to the height at which the clamping assembly 14 can clamp the barbell plate 17. Then, the clamping assembly 14 is moved along a direction perpendicular to the axis of the barbell bar 16 by the second moving seat 131. The clamping assembly 14 clamps the barbell plate 17 and removes the barbell plate 17 from the barbell bar 16, realizing automatic plate removal of the barbell. This reduces the manpower required for barbell plate removal. The plate removal process is highly automated and can effectively reduce the physical strength consumed by barbell plate removal.

[0060] Furthermore, the barbell plate unloading device includes two second moving components 13 and two clamping components 14. The clamping components 14 correspond one-to-one with the second moving components 13. Each side of the first moving component 11 is provided with a second moving component 13 and a clamping component 14. The two clamping components 14 can work simultaneously to unload one barbell plate 17 on each side of the barbell bar 16 at the same time, so as to ensure the balance of the barbell and the stability of the support of the lifting component 12 during the plate unloading process, and prevent the barbell from tipping over.

[0061] Furthermore, the barbell unloading device includes two first moving components 11 and two lifting components 12. Each lifting component 12 corresponds one-to-one with a first moving component 11. The two lifting components 12 move and lift synchronously, providing two fulcrums for the barbell bar 16. This further improves the stability and reliability of the lifting components 12's support for the barbell bar 16 during unloading, preventing the barbell from tipping over. In some examples, the lifting components 12 are positioned near the end of the barbell bar 16 to ensure sufficient spacing between the two lifting components 12, providing stable support for the barbell bar 16. Preferably, the two lifting components 12 are located symmetrically along the axial direction of the barbell bar 16.

[0062] Understandably, after the barbell plates 17 are installed on the barbell bar 16, the outermost barbell plates 17 are limited by the barbell plate 17 retainer, thereby limiting all the barbell plates 17 on one end of the barbell to prevent them from sliding on the barbell bar 16. When removing the plates, the user removes the barbell plate 17 retainer from the barbell bar 16, and then removes the barbell plates 17 from the barbell using the clamping assembly 14, thus achieving automatic plate removal from the barbell.

[0063] like Figure 1 and Figure 2 As shown, in one feasible embodiment, the first moving assembly 11 further includes: a first base plate 112, a first guide rail 113, a first lead screw 114, and a first driving device 115; the first guide rail 113 is disposed on the first base plate 112 along the length direction of the first base plate 112, and the first moving seat 111 is slidably connected to the first guide rail 113; the first lead screw 114 is disposed parallel to the first guide rail 113, and the first lead screw 114 is rotatably connected to the first base plate 112; a first adjusting block is threadedly connected to the first lead screw 114, and the first adjusting block is connected to the first moving seat 111; the first driving device 115 is disposed on the first base plate 112, and the output shaft of the first driving device 115 is connected to the first lead screw 114, and the first driving device 115 drives the first lead screw 114 to rotate.

[0064] In this technical solution, the first drive device 115 drives the first lead screw 114 to rotate, changing the position of the first adjusting block, and then drives the first moving seat 111 to move through the first adjusting block; the first moving seat 111 is slidably connected to the first guide rail 113, and the first guide rail 113 guides the movement of the first moving seat 111, and then drives the lifting assembly 12 to move along the trajectory of the first guide rail 113 through the first moving seat 111, and transports the barbell in or out of the barbell bar 16 along the predetermined trajectory.

[0065] Understandably, before unloading the weights, the lifting assembly 12 moves the barbell toward the clamping assembly 14; after unloading the weights, the lifting assembly 12 transports the unloaded barbell bar 16 out so that the next user can install the weight plates 17 on the barbell bar 16, ensuring the continuity of use of the barbell bar 16.

[0066] like Figure 1 As shown, in one feasible implementation, the width of the first base plate 112 is equal to the distance between the two innermost barbell plates 17 on the barbell bar 16.

[0067] In this technical solution, by making the width of the first base plate 112 the same as the distance between the two innermost barbell plates 17 on the barbell bar 16, the first base plate 112 is used to limit the barbell on the ground, so that the lifting assembly 12 can be located in the middle of the barbell, thereby improving the balance and stability of the barbell transport process.

[0068] It should be noted that a fixing block 18 is provided on the barbell bar 16. The fixing block 18 and the corresponding barbell plate 17 retainer cooperate to limit all the barbell plates 17 installed on one end of the barbell. The retainer is used to limit the outermost barbell plate 17, and the fixing block 18 is used to limit the innermost barbell plate 17. Therefore, the distance between the two innermost barbell plates 17 at both ends of the barbell bar 16 is a fixed value. By setting the width of the first base plate 112 to the distance between the two innermost barbell plates 17, the barbell can be placed centered on the first base plate 112. This allows the two lifting components 12 to support the barbell in symmetrical positions along the axial direction of the barbell bar 16, ensuring support stability.

[0069] like Figures 1 to 3 As shown, in one feasible embodiment, the lifting assembly 12 includes: a linear telescopic device 121, a lifting frame 122, and a support base 123; the linear telescopic device 121 is vertically arranged, and the fixed end of the linear telescopic device 121 is connected to the first movable seat 111; the lifting frame 122 is horizontally arranged, and the lifting frame 122 is connected to the telescopic end of the linear telescopic device 121; the support base 123 is arranged on the top surface of the lifting frame 122 to support the barbell rod 16.

[0070] In this technical solution, the linear telescopic device 121 is fixed on the first movable seat 111, the lifting frame 122 is horizontally arranged at the telescopic end of the linear telescopic device 121, and the support seat 123 is arranged on the lifting frame 122. The support seat 123 is used to support and limit the barbell bar 16. The linear telescopic device 121 is vertically arranged. The linear telescopic device 121 drives the lifting frame 122 and the support seat 123 to move, thereby adjusting the height of the barbell bar 16 so that the height of the barbell bar 16 and the barbell plate 17 can be adapted to the height of the clamping assembly 14.

[0071] Specifically, the linear telescopic device 121 can be any one of a cylinder, a hydraulic cylinder, or an electric push rod.

[0072] In one feasible implementation, a positioning groove is provided on the top surface of the support base 123, and the positioning groove extends through the support base 123 along the width direction of the first moving component 11, so that at least a portion of the barbell bar 16 can be embedded in the positioning groove; wherein, the shape of the positioning groove is adapted to the shape of the side wall of the barbell bar 16.

[0073] In this technical solution, when the barbell bar 16 is placed on the support base 123, the bottom of the barbell bar 16 is embedded in the positioning groove to limit the barbell bar 16, prevent the barbell bar 16 from sliding and rolling relative to the linear telescopic device 121, ensure the stability of the barbell bar 16 during movement and lifting, prevent the barbell bar 16 from moving randomly, and thus help ensure the accuracy of the position and height adjustment control of the barbell bar 16.

[0074] like Figure 2 and Figure 3 As shown, in one feasible embodiment, the lifting assembly 12 further includes: a limiting frame 124 and a guide column 125; the limiting frame 124 is horizontally arranged at the fixed end of the linear telescopic device 121; the guide column 125 is vertically arranged, one end of the guide column 125 is connected to the lifting frame 122, the guide column 125 passes through the limiting frame 124, and the limiting frame 124 and the guide column 125 are slidably connected.

[0075] In this technical solution, the limiting frame 124 is fixed on the fixed end of the linear telescopic device 121, and the guide column 125 is fixed on the lifting frame 122. The guide column 125 passes through the limiting frame 124 and is slidably connected to the limiting frame 124. When the lifting frame 122 is raised and lowered, the guide column 125 guides the movement of the lifting frame 122, thereby ensuring that the lifting frame 122 remains horizontal during the raising and lowering process and preventing the lifting frame 122 from tilting or deforming due to excessive pressure from the barbell. This ensures that the lifting frame 122 remains horizontal at all times and provides stable and reliable support for the barbell bar 16.

[0076] Specifically, at least two guide posts 125 are provided to ensure that the guide posts 125 limit the movement of the lifting frame 122 during the lifting process.

[0077] like Figure 1 , Figure 2 and Figure 4 As shown, in one feasible embodiment, the second moving component 13 further includes: a second base plate 132, a second guide rail 133, a second lead screw 134, and a second driving device 135; the second base plate 132 is arranged perpendicular to the first moving component 11; the second guide rail 133 is arranged on the second base plate 132 along the length direction of the second base plate 132, and the second moving seat 131 is slidably connected to the second guide rail 133; the second lead screw 134 is arranged parallel to the second guide rail 133, and the second lead screw 134 is rotatably connected to the second base plate 132; a second adjusting block is threaded onto the second lead screw 134, and the second adjusting block is connected to the second moving seat 131; the second driving device 135 is arranged on the second base plate 132, and the output shaft of the second driving device 135 is connected to the second lead screw 134, and the second driving device 135 drives the second lead screw 134 to rotate.

[0078] In this technical solution, the second drive device 135 drives the second lead screw 134 to rotate, changing the position of the second adjusting block, and then drives the second moving seat 131 to move through the second adjusting block; the second moving seat 131 is slidably connected to the second guide rail 133, and the second guide rail 133 guides the movement of the second moving seat 131, and then drives the clamping assembly 14 to move in a direction perpendicular to the barbell bar 16 through the second moving seat 131, so that the barbell plate 17 can be smoothly removed from the barbell bar 16.

[0079] Furthermore, a clamping component 14 clamps one barbell plate 17 at a time. The clamping component 14 first clamps the outermost barbell plate 17. After the barbell plate 17 on the clamping component 14 is placed on the barbell plate 17 rack, the clamping component 14 then clamps the next adjacent barbell plate 17.

[0080] It should be noted that the action of placing the barbell plates 17 on the barbell plate rack can be performed by the user or by the clamping component 14. When the user places the barbell plates 17 on the barbell plate rack, the plate unloading device transports the barbell plates 17 to the vicinity of the barbell plate rack, shortening the distance the user has to move the barbell plates 17 and reducing the work done by the user when transporting the barbell plates 17, thus achieving the effect of effortless plate unloading. When the action of placing the barbell plates 17 on the barbell plate rack is performed by the clamping component 14, the barbell plate rack needs to have a channel for the clamping component 14 to move. The clamping component 14 can move to the deepest part of the barbell plate rack, and then place the barbell plates 17 on the barbell rack in sequence through the clamping component 14, realizing the automatic unloading and storage of the barbell plates.

[0081] Furthermore, when the action of placing the barbell plates 17 on the barbell plate 17 rack is completed by the clamping assembly 14, the barbell plate 17 rack is arranged along the length direction of the second moving assembly 13, and the second guide rail 133 extends into the channel of the barbell plate 17 rack, so that the picking assembly can clamp the barbell plates 17 and move them to any position on the barbell plate 17 rack. Specifically, the barbell plate 17 rack and the clamping assembly 14 correspond one-to-one. The barbell plate 17 rack includes a first support part, a second support part, and a support plate. The first support part and the second support part are arranged opposite to each other, and a moving channel is formed between the first support part and the second support part for the clamping assembly 14 and the second guide rail 133 to pass through. The support plate is located at the end of the first support part away from the first moving assembly 11 to support the upright barbell plates 17. The clamping assembly 14 sequentially places the barbell plates 17 from the support plate toward the direction of the first moving assembly 11.

[0082] like Figure 1 , Figure 2 and Figure 5As shown, in one feasible embodiment, the clamping assembly 14 includes: a mounting frame 141, a gripper 142, two reduction motors 143, and two gears 144; the mounting frame 141 is mounted on the second movable seat 131; the gripper 142 is mounted on the mounting frame 141; the gripper 142 includes a fixing part 1421 and two gripping arms 1422, the fixing part 1421 is fixed on the mounting frame 141, and the two gripping arms 1422 are rotatably connected to the fixing part 1421; the reduction motors 143 are mounted on the mounting frame 141; the gears 144 are mounted on the output shaft of the reduction motors 143, and the gears 144 correspond one-to-one with the reduction motors 143, and the two gears 144 are meshed; the gears 144 are connected to the gripping arms 1422, and the gripping arms 1422 correspond one-to-one with the gears 144, and the gripping arms 1422 and the gears 144 rotate coaxially, and the meshing of the two gears 144 drives the two gripping arms 1422 to move in opposite directions.

[0083] In this technical solution, the gripper 142 is mounted on the mounting bracket 141 to improve the load-bearing capacity of the gripper 142; the gripper arm 1422 rotates synchronously and coaxially with the corresponding gear 144 and the output shaft of the reduction motor 143. Through the meshing of the two gears 144, the two gripper arms 1422 are driven to move in the same or opposite directions, thereby completing the action of clamping or releasing the gripper 142. By using the precise transmission of the gear 144, the clamping force of the gripper 142 is precisely controlled to ensure that the clamping force on the barbell plate 17 is moderate and to ensure the stability of the gripper 142 in clamping the barbell plate 17.

[0084] Understandably, by optimizing the transmission ratio and transmission accuracy of the geared motor 143 and gear 144, and by adjusting the rotation angle of gear 144, the clamping force is automatically adjusted according to the different sizes and weights of the barbell plates 17, thereby improving the reliability and adaptability of clamping the barbell plates 17.

[0085] like Figure 5 As shown, in one feasible embodiment, the barbell plate unloading device further includes: a clamping groove 15, which is disposed on the clamping surface of the clamping arm 1422, and at least a portion of the barbell plate 17 is embedded in the clamping groove 15; wherein, the clamping surface is the opposite side of the two clamping arms 1422.

[0086] In this technical solution, the barbell plate 17 is clamped by two clamping arms 1422 with the clamping surfaces of the two clamping arms 1422 facing each other. The clamping surfaces are provided with clamping grooves 15, and the two clamping grooves 15 form a clamping cavity for the barbell plate 17. By clamping, the barbell plate 17 is confined in the clamping cavity, thereby improving the stability of clamping the barbell plate 17 and preventing the barbell plate 17 from slipping off.

[0087] Furthermore, an anti-slip pad is provided on the wall of the clamping groove 15. The anti-slip pad is fixedly connected to the clamping arm 1422. The anti-slip pad is elastic. When the barbell plate 17 squeezes the anti-slip pad, the anti-slip pad undergoes elastic deformation to increase the friction between the anti-slip pad and the barbell plate 17, thereby preventing the barbell plate 17 from slipping and further improving the stability of clamping the barbell plate 17.

[0088] like Figure 5 As shown, in one feasible embodiment, the clamping groove 15 is V-shaped.

[0089] In this technical solution, by setting the clamping groove 15 into a V-shape, a diamond-shaped clamping cavity is formed between the two clamping arms 1422. The two clamping arms 1422 clamp the barbell plate 17 at four points, which not only ensures the stability of clamping the barbell plate 17, but also adapts to barbell plates 17 of different diameters, improving the adaptability and practicality of the clamping arms 1422. Furthermore, after the barbell plate 17 is embedded in the clamping cavity, the clamping arms 1422 provide support for the barbell plate 17, which can further reduce the possibility of the barbell plate 17 sliding down due to gravity.

[0090] It will be readily understood by those skilled in the art that the above embodiments can be freely combined and superimposed without conflict.

Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application. The above are merely preferred embodiments of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this application, and these improvements and modifications should also be considered within the protection scope of this application.
