Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Reference Figures 1 to 8 The first embodiment of this utility model proposes a shelf robot welding workstation, which includes: a welding robot 10, a rotation and positioning mechanism 20, a rotating table 30, and at least two positioning mechanisms 40. The welding robot 10 is located next to the rotating table 30, which is located at the output end of the rotary displacement mechanism 20. The at least two positioning mechanisms 40 are disposed on the rotating table 30 and distributed around the rotating displacement mechanism 20. The rotating displacement mechanism 20 drives the rotating table 30 to rotate so as to drive one of the positioning mechanisms 40 into the welding work area of ​​the welding robot 10, while the remaining positioning mechanisms 40 are located in the material loading area. The positioning mechanism 40 includes at least one clamp 41; the clamp 41 includes a first positioning component 411, a second positioning component 412, a third positioning component 413, and an opening and closing drive component 414; The first positioning component 411, the second positioning component 412 and the opening and closing drive component 414 are all disposed on the rotating table 30, and the third positioning component 413 is disposed at the output end of the opening and closing drive component 414; The opening and closing drive component 414 drives the third positioning component 413 to close and cooperate with the first positioning component 411 to clamp the frame 110 of the shelf 100; the opening and closing drive component 414 drives the third positioning component 413 to close and cooperate with the second positioning component 412 to clamp the legs 120 of the shelf 100.

[0022] In the initial state: the rotating table 30 is stationary, one of the positioning mechanisms 40 is within the working range of the welding robot 10, and the other positioning mechanisms 40 are within the loading area, so that loading and welding operations can be carried out simultaneously; Loading and clamping in the loading area: The worker or robot places the frame 110 of the shelf 100 on the first positioning component 411 in the area, and places the frame legs 120 of the shelf 100 on the second positioning component 412 in the area. Then, the control system is operated so that the opening and closing drive component 414 drives the third positioning component 413 to synchronously close and cooperate with the first positioning component 411 and the second positioning component 412, thereby completing the loading and clamping of the shelf 100 in this station.

[0023] Once the welding operation at the welding station and the clamping operation at the loading station are completed, the control system activates the rotary positioning mechanism 20. This mechanism drives the rotary table 30 to rotate by a specified angle, allowing the station that completed the welding operation to enter the loading area, and the station that completed the loading and clamping operation to enter the working range of the welding robot 10. This cycle repeats continuously, achieving continuous and automated batch production. This reduces the idle time of the welding robot 10, thereby improving the equipment's production efficiency. Furthermore, it quickly adapts to the positional limitations of shelves 100 of different sizes and specifications, increasing the variety of weldable shelves 100 and improving equipment utilization.

[0024] The shelf robot welding workstation of this utility model switches between the positioning mechanism 40 and the rotation and displacement mechanism 20 of the dual-station welding fixture. During the welding process of the welding robot 10, the operator can unload and load materials at the loading station, which avoids the waste of time when the welding robot 10 is idle and effectively improves the production efficiency of the welding robot 10.

[0025] In some specific embodiments, based on some relatively simple and small-sized shelving 100, the frame 110 and the legs 120 of the shelving 100 are clamped by a clamp 41.

[0026] In some other embodiments, the shelves 100 are clamped by two or more clamps 41 arranged side by side, according to some elongated shelf 100.

[0027] In some other embodiments, the square shelf 100 is clamped by two or four clamps 41 arranged at the four opposite corners.

[0028] The number and distribution of clamps 41 are adjusted appropriately according to the style of shelf 100.

[0029] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 2 to 5 , Figure 7 and Figure 8 The third positioning component 413 includes an arm body rotating support 4131, a rotating arm 4132, a first pressing member 4133, and a second pressing member 4134; The opening and closing drive component 414 and the arm body rotating support 4131 are both located on the rotating platform 30. The middle part of the rotating arm 4132 is rotatably connected to the arm body rotating support 4131, and one end of the rotating arm 4132 is located at the output end of the opening and closing drive component 414; The first pressing member 4133 and the second pressing member 4134 are spaced apart at the other end of the rotating arm 4132; The opening and closing drive component 414 drives the first pressing member 4133 to close and cooperate with the first positioning component 411 to clamp the frame 110, and the opening and closing drive component 414 drives the second pressing member 4134 to close and cooperate with the second positioning component 412 to clamp the frame leg 120.

[0030] In this embodiment, after the frame 110 and the frame leg 120 are both placed in the designated position, the drive rod of the corresponding opening and closing drive component 414 performs a telescopic movement, causing the rotating arm 4132 to rotate around the arm body rotating support 4131 as the rotation center: the drive rod of the opening and closing drive component 414 pulls one end of the rotating arm 4132 to move and rotate in the first direction, and the other end of the corresponding rotating arm 4132 moves and rotates in the opposite direction of the first direction; so that the first pressing member 4133 on the other end of the rotating arm 4132 closes and cooperates with the first positioning component 411, and the second pressing member 4134 closes and cooperates with the second positioning component 412.

[0031] When the shelf 100 needs to be removed, the drive rod of the opening and closing drive component 414 pulls one end of the rotating arm 4132 to move and rotate in the opposite direction of the first direction, and the other end of the corresponding rotating arm 4132 moves and rotates in the first direction; so that the first pressing member 4133 on the other end of the rotating arm 4132 moves away from the first positioning component 411, and the second pressing member 4134 moves away from the second positioning component 412.

[0032] The robotic welding workstation of this invention improves the overall compactness of the equipment and has a simple structure.

[0033] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 2 to 5 , Figure 7 The rotating arm 4132 includes a first arm body 41321, an arm body rotating seat 41322, a second arm body 41323, and a third arm body 41324; The output end of the opening and closing drive component 414, the first arm body 41321, the arm body rotating seat 41322, the second arm body 41323, and the third arm body 41324 are connected in sequence; the arm body rotating seat 41322 is rotatably connected to the arm body rotating support 4131, and the rotation axis of the arm body rotating seat 41322 is parallel to the surface of the rotating platform 30; The first arm body 41321 and the output end of the opening and closing drive component 414 are arranged to intersect each other and both intersect the surface of the rotating platform 30; The first pressing member 4133 is disposed on the third arm body 41324, and the first pressing member 4133 is used to press down the frame body 110; The second pressing member 4134 is provided on the second arm body 41323, and the second pressing member 4134 is used to press down the frame leg 120.

[0034] In this embodiment, the arm rotating seat 41322 serves as a rotation fulcrum. When the opening and closing drive component 414 drives the first arm 41321 to move and rotate in the first direction, the second pressing member 4134 on the second arm 41323 closes and engages with the second positioning component 412, and the first pressing member 4133 on the third arm 41324 closes and engages with the first positioning component 411. The first positioning component 411 and the first pressing member 4133 respectively abut against the lower and upper parts of the frame 110 to ensure the stable placement of the frame 110. The second positioning component 412 and the second pressing member 4134 respectively abut against the lower and upper parts of the frame leg 120 to ensure the stable placement of the frame leg 120.

[0035] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figure 7 and Figure 8The opening and closing drive component 414 includes an opening and closing drive member 4141, a drive rotary support 4142, and a drive rotary rod 4143. The drive rotary support 4142 is disposed on the rotating platform 30 and has a rotating hole. The drive rotary rod 4143 is rotatably disposed in the rotating hole and is also connected to the opening and closing drive member 4141. The opening and closing drive member 4141 rotates through the drive rotary support 4142 and the drive rotary rod 4143. Adjusting the angle between the opening and closing drive member 4141 and the rotating platform 30 allows the opening and closing drive member 4141 to shorten the stroke required to extend and retract the rotating arm 4132, thereby improving the efficiency of clamping and positioning.

[0036] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 2 to 8 Two first positioning components 411 are provided, and the second positioning component 412 is located between the two first positioning components 411; the two first positioning components 411 and the second positioning component 412 are arranged in a triangular distribution.

[0037] In this embodiment, the current type of clamp 41 is adapted to hold the bracket leg 120 positioned diagonally opposite the shelf 100 of the frame 110. The second arm 41323 of the rotating arm 4132 is connected to the middle of the third arm 41324. The second arm 41323 and the connecting body of the third arm 41324 form two L-shaped relief grooves 41325. The connection between the bracket leg 120 and the transverse side of the frame 110 and the connection between the bracket leg 120 and the longitudinal side of the frame 110 are respectively located within the area of ​​the L-shaped relief groove 41325, so as to facilitate the welding robot 10 to perform welding operations at these two connections.

[0038] In some embodiments of the robotic welding workstation of this invention, the two first positioning components 411 and the second positioning component 412 are aligned on the same straight line. The clamp 41 is suitable for clamping a type of shelf 100 in which the frame legs 120 are located in the middle of the frame body 110.

[0039] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 2 to 6 The first positioning component 411 includes a first receiving component 4111, a first limiting component 4112, a limiting translation driving component 4113, and a second limiting component 4114. The first receiving member 4111, the first limiting member 4112 and the limiting translation drive member 4113 are all provided on the rotating table 30, and the second limiting member 4114 is provided at the output end of the limiting translation drive member 4113; The first limiting member 4112 and the second limiting member 4114 enclose and form a limiting area; The first support member 4111 is located at the bottom opening of the limiting area to support the frame body 110, and the second positioning member 412 is located at the side opening of the limiting area.

[0040] In this embodiment, the first support member 4111 combined with the first pressure member 4133 is used to limit the position of the frame 110 in the vertical direction; the first limiting member 4112 combined with the second limiting member 4114 is used to limit the position of the frame 110 in the horizontal direction; and the other clamps 41 can limit the position in both the horizontal and vertical directions; thereby improving the stability of the position limitation of the frame 110, thereby improving the accuracy and consistency of welding.

[0041] The frame 110 in this embodiment includes a main frame plate 111 and multiple side frame plates 112. The multiple side frame plates 112 are vertically connected to the sides of the main frame plate 111 respectively, and the two sides of the frame legs 120 are respectively connected to two adjacent side frame plates 112.

[0042] According to the different thicknesses of the side shelf plates 112, the extension position of the output end of the limiting translation drive 4113 is adjusted to increase or decrease the distance between the first limiting member 4112 and the second limiting member 4114, thereby increasing the position limitation of the shelves 100 of different sizes.

[0043] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 2 to 6 The first positioning component 411 further includes a first lifting drive component 4115, which is disposed on the rotating platform 30, and the first supporting component 4111 is disposed at the output end of the first lifting drive component 4115. The second positioning component 412 includes a second lifting drive component 4121, a second receiving component 4122, and a third limiting component 4123; The second supporting member 4122 is disposed at the output end of the second lifting drive member 4121, and the third limiting member 4123 is disposed at the second supporting member 4122; The second support member 4122 is used to support the frame leg 120, and the third limiting member 4123 is used to pass through the cylindrical hole of the frame leg 120.

[0044] In this embodiment, based on the height dimensions of the side frame plates 112 of the frame 110, the height of the first supporting member 4111 is adjusted by the first lifting drive member 4115, so that the first supporting member 4111 supports the frame 110 with side frame plates 112 of different height dimensions; based on the height dimensions of the frame legs 120, the height of the second supporting member 4122 is adjusted by the second lifting drive member 4121, so that the second supporting member 4122 supports the frame legs 120 of different height dimensions.

[0045] In this embodiment, the support leg 120 is a cylindrical body with an internal bore. The outer peripheral wall of the support leg 120 is welded to the side frame 110 by a welding robot 10. In summary, by using the second support member 4122 to support the column end face of the bottom side of the support leg 120, and by using the third limiting member 4123 to pass through the bore of the support leg 120, the position of the support leg 120 is limited in the horizontal direction. Combined with the third positioning member 413, the position of the support leg 120 is limited in the vertical direction.

[0046] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figure 4 and Figure 6 The second limiting member 4114 includes a connecting plate 41141 and a limiting plate 41142; The connecting plate 41141 is located at the output end of the limiting translation drive 4113, and the limiting plate 41142 is located on the connecting plate 41141. The limiting plate 41142 is provided with a first limiting groove, which is used to limit the mesh strip of the frame 110.

[0047] In this embodiment, the mesh strips of the frame 110 are limited by the first limiting groove on the limiting plate 41142. Specifically, the side frame plate 112 includes two side mesh strips 1121 and a connecting mesh strip 1122, with the connecting mesh strip 1122 disposed between the two side mesh strips 1121. The top side mesh strip 1121 is connected to the main frame plate 111. The first limiting groove is used to limit the position of the side mesh strips 1121, thereby limiting the position of the frame 110 in the vertical direction.

[0048] In other embodiments of the robotic welding workstation for shelves based on this utility model, two first limiting grooves are provided; the limiting plate 41142 includes a first limiting plate 41142 body and a second limiting plate 41142 body, the second limiting plate 41142 body is slidably connected to the first limiting plate 41142 body, and the two first limiting grooves are respectively provided on the first limiting plate 41142 body and the second limiting plate 41142 body. According to the distance between the two side mesh strips 1121, the second limiting plate 41142 is adjusted to slide on the first limiting plate 41142 body to increase or decrease the distance between the two side mesh strips 1121, further enriching the size types of the weldable and positionable shelf 100.

[0049] In some embodiments of the robotic welding workstation of this utility model, reference is made to... Figures 1 to 3 The positioning mechanism 40 includes at least two clamps 41, a longitudinal translation component 42, and a lateral translation component 43; The longitudinal translation component 42 is disposed on the rotating platform 30, and the lateral translation component 43 is disposed at the output end of the lateral translation component 43; One of the clamps 41 is located at the output end of one of the lateral translation components 43.

[0050] In this embodiment, the clamps 41 are arranged in pairs to clamp and position the shelf 100. The position is adjusted in two horizontal directions by the longitudinal translation component 42 and the lateral translation component 43 to meet the clamping and positioning of shelves 100 with different width and length dimensions.

[0051] In some embodiments of the robotic welding workstation of this utility model, reference is made to...

[0052] In this embodiment, the longitudinal translation component 42 and the lateral translation component 43 achieve stable movement of the clamp 41 in two horizontal directions through the linear drive component 401, the linear guide component 402, and the translation slide plate 403.

[0053] In some embodiments of the robotic welding workstation of this utility model, the linear drive 401 is an adjustable lead screw type drive, which includes a lead screw fixing seat, a lead screw support seat, a lead screw, a lead screw nut, and a handwheel.
