Description

Technical Field

[0001] The utility model belongs to the technical field of welding, and in particular relates to a pressure plate gripping device and a welding station. Background Art

[0002] Currently, battery trays in the new energy vehicle field mostly use FSW welding technology. Some battery tray welding equipment includes a pressure plate for pressing on the battery tray to be welded and a gripper for picking up and placing the pressure plate. However, due to the lack of positioning function or low positioning accuracy between the gripper and the pressure plate, the pressure plate will be placed at an angle, which will cause interference between the pressure plate and the welding spindle, resulting in a collision, posing a safety hazard and adversely affecting the welding quality of the battery tray. Utility Model Content

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. To this end, one purpose of the present invention is to provide a pressure plate gripper device with high automation, high positioning accuracy, high safety, and the ability to improve welding quality.

[0004] The pressure plate gripping device according to an embodiment of the present invention includes:

[0005] A pressing plate, the pressing plate comprising a pressing plate body, a hanging block and a pressing plate positioning assembly; the hanging block and the pressing plate positioning assembly are arranged on the pressing plate body;

[0006] The gripping mechanism includes a mounting bracket, a hanging plate driving component, a hanging plate, a grabbing assembly and a hanging plate positioning assembly; the hanging plate driving component is arranged on the mounting bracket and is connected to the hanging plate to drive the hanging plate to move up and down; the grabbing assembly is arranged on the hanging plate for connecting to and separating from the hanging block; the hanging plate positioning assembly is arranged on the hanging plate for cooperating with the pressure plate positioning assembly to accurately position the hanging plate on the pressure plate.

[0007] During operation, the workpiece to be welded is located at a designated position below the pressure plate gripper device. The gripper mechanism cooperates with the pressure plate positioning assembly of the pressure plate through the hanging plate positioning assembly to ensure that the pressure plate is in the correct position relative to the gripper mechanism, such as keeping the pressure plate in a horizontal position and not tilting, so as to achieve precise positioning of the pressure plate relative to the gripper mechanism. At the same time, the gripper mechanism is reliably connected to the hanging block of the pressure plate through the gripping assembly. The hanging plate drive drives the hanging plate and the pressure plate down, so that the pressure plate can be accurately placed on the workpiece to be welded, avoiding the pressure plate from being tilted on the workpiece to be welded, thereby avoiding interference between the pressure plate and the welding spindle, avoiding collisions, and reducing safety hazards. At the same time, the gripper mechanism accurately places the pressure plate on the workpiece to be welded, which is also beneficial to improving the welding quality of the workpiece to be welded. After the pressure plate is placed on the workpiece to be welded, the gripping assembly separates from the hanging block, and the hanging plate drive drives the hanging plate to rise, so that the hanging plate positioning assembly separates from the pressure plate positioning assembly, that is, the gripper mechanism is separated from the pressure plate, so that the welding spindle can weld the workpiece to be welded. When the pressure plate needs to be removed after the workpiece to be welded is welded, the hanger plate driving component drives the hanger plate down. After the hanger plate positioning component cooperates with the pressure plate positioning component and is connected to the hanging block through the grabbing component, the hanger plate driving component drives the hanger plate and the pressure plate to rise, waiting for the next time to place the pressure plate on the next workpiece to be welded.

DETAILED DESCRIPTION

[0032] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0033] The following combination Figures 1 to 7 The platen gripper device 300 and the welding station 1000 according to an embodiment of the present invention will be described.

[0034] like Figure 1-7 As shown, the platen gripper device 300 of the present invention can be applied to a welding station 1000, for example, a gantry FSW fully automated intelligent welding station 1000 for welding workpieces such as battery trays. The platen gripper device 300 includes a platen 31 and a gripper mechanism 32. The platen 31 is used to press on the workpiece to be welded, such as a battery tray, and the gripper mechanism 32 is used to place the platen 31 on the workpiece to be welded and remove the platen 31 from the workpiece to be welded.

[0035] Specifically, the pressure plate 31 includes a pressure plate body 310, a hanging block 311 and a pressure plate positioning assembly 312; the hanging block 311 and the pressure plate positioning assembly 312 are arranged on the pressure plate body 310, for example, on the upper side of the pressure plate body 310, and the lower side of the pressure plate body 310 faces the workpiece to be welded.

[0036] The gripper mechanism 32 includes a mounting bracket 320, a hanger plate driving member 321, a hanger plate 322, a gripping assembly 323, and a hanger plate positioning assembly 324; the mounting bracket 320 is suitable for being mounted on a structural component of the welding station 1000, such as Figure 7 On the crossbeam of the welding station 1000 shown; the hanger plate driving member 321 can use a cylinder but is not limited to a cylinder. The hanger plate driving member 321 is arranged on the mounting bracket 320 and is connected to the hanger plate 322 to drive the hanger plate 322 to move up and down; the grabbing assembly 323 is arranged on the hanger plate 322, for example, on the lower side of the hanger plate 322, for connecting and separating with the hanger block 311; the hanger plate positioning assembly 324 is arranged on the hanger plate 322, for example, on the lower side of the hanger plate 322, for cooperating with the pressure plate positioning assembly 312 to accurately position the pressure plate 31, even if the position of the pressure plate 31 relative to the gripping mechanism 32 is correct.

[0037] When working, the workpiece to be welded is located at the specified position below the pressure plate gripper device 300, and the gripper mechanism 32 cooperates with the pressure plate positioning component 312 of the pressure plate 31 through the hanging plate positioning component 324, so that the position of the pressure plate 31 relative to the gripper mechanism 32 is correct, such as keeping the pressure plate 31 in a horizontal position without tilting, so as to achieve accurate positioning of the pressure plate 31 relative to the gripper mechanism 32. At the same time, the gripper mechanism 32 is reliably connected to the hanging block 311 of the pressure plate 31 through the gripping component 323, and the hanging plate 322 and the pressure plate 31 are driven down by the hanging plate driving member 321, so that the pressure plate 31 can be accurately placed on the workpiece to be welded, thereby avoiding the pressure plate 31 from being tilted on the workpiece to be welded, thereby avoiding interference between the pressure plate 31 and the welding spindle, avoiding collision with the machine, and reducing safety hazards. At the same time, the gripper mechanism 32 accurately places the pressure plate 31 on the workpiece to be welded, which is also conducive to improving the welding quality of the workpiece to be welded. After the pressure plate 31 is placed on the workpiece to be welded, the grabbing assembly 323 separates from the hanging block 311, and the hanging plate driving member 321 drives the hanging plate 322 to rise, so that the hanging plate positioning assembly 324 separates from the pressure plate positioning assembly 312, that is, the gripping mechanism 32 is separated from the pressure plate 31, so that the welding spindle can weld the workpiece to be welded. When the workpiece to be welded needs to be welded and the pressure plate 31 needs to be removed, the hanging plate driving member 321 drives the hanging plate 322 to descend. After the hanging plate positioning assembly 324 cooperates with the pressure plate positioning assembly 312 and is connected to the hanging block 311 through the grabbing assembly 323, the hanging plate driving member 321 drives the hanging plate 322 and the pressure plate 31 to rise, waiting for the next time to place the pressure plate 31 on the next workpiece to be welded.

[0038] The pressure plate gripper device 300 of the embodiment of the present invention, on the one hand, realizes the automatic gripping and releasing of the pressure plate 31 by the gripper mechanism 32 by setting the hanging plate driving member 321, the gripping assembly 323 and the hanging block 311, thereby improving the degree of automation, reducing manpower and improving the production rhythm. On the other hand, through the hanging plate positioning assembly 324 and the pressure plate positioning assembly 312, high-precision positioning of the pressure plate 31 is achieved, ensuring that the pressure plate 31 is accurately placed on the workpiece to be welded, avoiding the pressure plate 31 from being tilted on the workpiece to be welded, and thus avoiding interference between the pressure plate 31 and the welding spindle, avoiding collision with the machine, reducing safety hazards, and also helping to improve the welding quality of the workpiece to be welded.

[0039] In some embodiments, the pressure plate positioning assembly 312 includes a first positioning bushing 3121, and the hanger plate positioning assembly 324 includes a vertically extending first positioning column 3241, which is used to cooperate with the first positioning bushing 3121 to achieve high-precision positioning of the pressure plate 31; the first positioning column 3241 and the first positioning bushing 3121 can be arranged in multiple groups to better achieve high-precision positioning of the pressure plate 31. Alternatively, the pressure plate positioning assembly 312 includes a vertically extending second positioning column (not shown in the figure), and the hanger plate positioning assembly 324 includes a second positioning bushing (not shown in the figure), which is used to cooperate with the second positioning bushing to achieve high-precision positioning of the pressure plate 31; the second positioning bushing and the second positioning column can be arranged in multiple groups to better achieve high-precision positioning of the pressure plate 31.

[0040] In some embodiments, the pressure plate positioning assembly 312 further includes a first limiting post 3122, and the hanger plate positioning assembly 324 further includes a second limiting post 3242, and the second limiting post 3242 is directly opposite to the first limiting post 3122. By providing the first limiting post 3122 and the second limiting post 3242, on the one hand, the positioning accuracy of the pressure plate 31 can be further improved, and on the other hand, the lowest position of the hanger plate 322 is limited, ensuring that there is a reasonable space between the hanger plate 322 and the pressure plate 31 when the hanger plate 322 is lowered to the lowest position, thereby preventing the components on the lower side of the hanger plate 322, such as the grabbing assembly 323 and the first positioning bushing 3121, and the components on the upper side of the pressure plate body 310, such as the hanging block 311 and the first positioning post 3241, from being crushed. On the other hand, when the gripping mechanism 32 needs to remove the pressure plate 31, it is convenient for the grabbing assembly 323 to be connected to the hanging block 311. Preferably, the first limiting posts 3122 and the second limiting posts 3242 may be provided in multiple groups.

[0041] In some embodiments, the gripping mechanism 32 further includes a vertically extending linear guide assembly 325 for slidingly guiding the hanging plate 322. The linear guide assembly 325 includes a guide rail 3251 and a slider 3252. The guide rail 3251 is fixed to the mounting bracket 320, and the slider 3252 is fixed to the hanging plate 322. The slider 3252 slides with the guide rail 3251. By providing the linear guide assembly 325, on the one hand, the guiding accuracy is high, which is conducive to the hanging plate 322 and the components on the hanging plate 322 to be able to rise and fall smoothly without shaking. At the same time, the positioning accuracy of the pressure plate 31 can be further improved. On the other hand, the linear guide assembly 325 has a good load-bearing capacity, which allows the gripping mechanism 32 to lift a larger pressure plate 31 and has good applicability. Preferably, multiple groups of linear guide assemblies 325 can be provided.

[0042] In some embodiments, the gripping mechanism 32 also includes a buffer 326, which is distributed on the hanging plate 322 and the mounting bracket 320. When the gripping mechanism 32 grabs the pressure plate 31 and moves upward, the buffer 326 can effectively avoid noise, reduce the movement speed, and extend the service life of the gripping mechanism 32.

[0043] In some embodiments, a horizontally extending pin hole is provided on the hanging block 311; the grabbing assembly 323 includes a pin driving member 3231 and a horizontally extending pin 3232 connected to each other, the pin driving member 3231 can be a cylinder but is not limited to a cylinder, the pin driving member 3231 is fixed on the hanging plate 322 and connected to the pin 3232 to drive the pin 3232 to move horizontally, so that the pin 3232 is inserted into and exits the pin hole.

[0044] In detail, the grabbing assembly 323 also includes a driver mounting block 3233 , which is fixed to the lower side of the hanging plate 322 , and the latch driver 3231 is fixed on the driver mounting block 3233 , which also serves as a guide for the latch 3232 .

[0045] Preferably, multiple groups of the hanging blocks 311 and the grabbing assemblies 323 can be provided so that the grabbing mechanism 32 can reliably grab the pressing plate 31 .

[0046] In some embodiments, the pressure plate 31 also includes a floating pressing mechanism 313, which is distributed around the pressure plate body 310; the floating pressing mechanism 313 includes a floating mounting block 3131, a guide sleeve 3132, a guide column 3133, a pressure head 3134 and an elastic member 3135; the floating mounting block 3131 is fixed on the upper side of the pressure plate body 310, the guide sleeve 3132 is fixed in the floating mounting block 3131, and the guide column 3133 can slide up and down through the guide sleeve 3132, the floating mounting block 3131, and the pressure plate body 310, and the upper end of the guide column 3133 has a blocking portion, which can prevent the guide column 3133 from falling off, and the lower end of the guide column 3133 is fixed to the pressure head 3134 located on the lower side of the pressure plate 31, and the pressure head 3134 is used to directly press on the workpiece to be welded, and the elastic member 3135 is arranged between the floating mounting block 3131 and the pressure head 3134. By providing a floating clamping mechanism 313 around the periphery of the clamping plate body 310 and directly pressing the pressure head 3134 of the floating clamping mechanism 313 against the workpiece to be welded, the clamping plate 31 is adapted to the flatness tolerance of the workpiece to be welded. This facilitates the clamping plate 31 to better clamp the workpiece to be welded, thereby improving welding quality. The floating clamping mechanism 313 has a simple structure and is easy to install.

[0047] In some embodiments, the floating pressing mechanism 313 further includes a floating adjustment member 3136 , which is used to adjust the floating height of the pressing head 3134 .

[0048] In some embodiments, the floating adjustment member 3136 is a limiting bolt, which is threadedly connected to the floating mounting block 3131 and the lower end of the limiting bolt abuts against the pressure head 3134. The limiting stud can easily adjust the floating height of the pressure head 3134.

[0049] In some embodiments, the floating clamping mechanism 313 also includes a pressing plate 3137, which is fixed to the upper side of the floating mounting block 3131, for example, fixed to the floating mounting block 3131 by a screw. The pressing plate 3137 presses the upper end surface of the guide sleeve 3132 to prevent the guide sleeve 3132 from moving up and down.

[0050] In some embodiments, the lower surface of the pressing head 3134 is provided with an avoidance recess (not shown in the figure), which can effectively avoid interference between the pressing head 3134 and the workpiece to be welded.

[0051] In some embodiments, the pressing plate 31 further includes locking blocks 314 located at the four corners of the lower side of the pressing plate body 310. The locking blocks 314 can rigidly clamp the four corners of the workpiece to be welded and simultaneously limit the floating clamping mechanism 313.

[0052] In some embodiments, a reinforcement portion 315 is provided on the upper side of the pressure plate body 310 . The reinforcement portion 315 may be a reinforcing rib to prevent the pressure plate body 310 from deforming.
