Description

Technical Field

[0001] The invention relates to the technical field of depalletizing clamps, and in particular to an integrated dual-purpose clamp tooling. Background Art

[0002] With the popularization of intelligent automation, robotic arms are widely used in the field of product depalletizing. For example, for the depalletizing of empty barrels of water, the robotic arms are hoisted with clamps to repeatedly clamp the empty barrels of water for depalletizing. In order to improve efficiency, the clamps are usually required to clamp a whole layer of empty barrels of water. However, the existing clamps for depalletizing a whole layer are complex in structure, for example, they require many driving parts. Moreover, usually a whole layer of empty barrels of water is set on a pallet. After the depalletizing of a whole layer of empty barrels of water is completed, the clamps need to be replaced to clamp the pallet before another layer of empty barrels of water can be unloaded. The work efficiency is low, and the use of two specifications of clamps is costly.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0034] The present embodiment provides an integrated dual-purpose clamp tooling, which has a simple and compact structure, low cost and high working efficiency.

[0035] Specific as Figures 1 to 5 As shown, the integrated dual-purpose clamp tooling includes a hanger assembly 100, a clamping assembly 200 and a hook stacking assembly 300. The hanger assembly 100 can be installed on a robotic arm. The clamping assembly 200 includes multiple groups of clamping members 210, a first driving member 220, a second driving member 230, a first connecting member and a second connecting member. Multiple groups of clamping members 210 are arranged at intervals along the first direction and are all slidably suspended on the hanger assembly 100 along the first direction. Each group of clamping members 210 includes two clamping strips 211 extending along the second direction, and the unloaded products (such as large barrels of water and empty barrels 10) can be clamped between the two clamping strips 211. The first connecting member is sequentially connected to the clamping strips 211 located at odd positions along the first direction, and the second connecting member is sequentially connected to the clamping strips 211 located at even positions along the first direction. The first driving member 220 and the second driving member 230 are both fixed to the hanger assembly 100; the driving ends of the first driving member 220 and the second driving member 230 are respectively connected to the two outermost clamping strips 211, and the driving directions are opposite. The hook stack assembly 300 includes a first hook frame 310, a second hook frame 320, a third driving member 330 and a fourth driving member 340. The first hook frame 310 and the second hook frame 320 are respectively located outside the two outermost clamping strips 211, and are both slidably arranged on the hanger assembly 100 along the first direction. The third driving member 330 and the fourth driving member 340 are both fixed to the hanger assembly 100; the driving ends of the third driving member 330 and the fourth driving member 340 are respectively connected to the first hook frame 310 and the second hook frame 320, and the driving directions are opposite.

[0036] Based on the above design, each group of clamping members 210 includes two clamping strips 211, which are used to clamp a whole row of products to be unloaded, and the clamping is simple; multiple groups of clamping members 210 can clamp multiple rows (whole layers) of products to be unloaded, and the work efficiency is high. The driving ends of the first driving member 220 and the second driving member 230 are respectively connected to the two outermost clamping strips 211, and the driving directions are opposite, so as to drive the two outermost clamping strips 211 to move closer to or away from each other along the first direction. The first connecting member sequentially connects the clamping strips 211 located at odd positions, and binds the clamping strips 211 located at odd positions to each other; the second connecting member sequentially connects the clamping strips 211 located at even positions, and binds the clamping strips 211 located at even positions to each other, so as to realize the synchronous linkage of multiple groups of clamping members 210, thereby eliminating the need for each clamping strip 211 to be equipped with a driving member. Therefore, only the first driving member 220 and the second driving member 230 can simultaneously drive the two clamping strips 211 in each group of clamping members 210 to move closer to or farther from each other, thereby achieving a clamping or loosening action to clamp a whole layer of products to be unloaded, and the structure is simple and compact. The hook stacking assembly 300 includes a first hook frame 310, a second hook frame 320, a third driving member 330 and a fourth driving member 340. The first hook frame 310 and the second hook frame 320 are respectively located outside the two outermost clamping strips 211 to avoid interference with the products to be unloaded; the driving ends of the third driving member 330 and the fourth driving member 340 are respectively connected to the first hook frame 310 and the second hook frame 320, and the driving directions are opposite, so that the first hook frame 310 and the second hook frame 320 move closer to or farther from each other along the first direction, thereby achieving a clamping or loosening action to clamp the pallet 20 of the products to be unloaded. Therefore, the integrated dual-purpose clamp tooling can not only realize the task of clamping a whole layer of products to be unloaded, but also realize the task of clamping the tray 20. It is a dual-purpose tooling with high work efficiency and cost saving.

[0037] It should be noted that the first direction is the width direction of the clamp 211 (direction A in the figure), and the second direction is the length direction of the clamp 211 (direction B in the figure), that is, the first direction and the second direction are perpendicular to each other; the first driving member 220 and the second driving member 230 are coaxially arranged along the first direction; and the third driving member 330 and the fourth driving member 340 are coaxially arranged along the first direction.

[0038] Exemplarily, the plurality of groups of clamping members 210 may be two groups, three groups, four groups or six groups, etc. In this embodiment, there are four groups of clamping members 210 , namely eight clamping strips 211 .

[0039] In this embodiment, the first driving member 220 , the second driving member 230 , the third driving member 330 , and the fourth driving member 340 are all cylinders, which have low cost.

[0040] In order to save space, the first driving member 220 and the second driving member 230 are arranged back to back, that is, the driving ends of the first driving member 220 and the second driving member 230 are extended to drive the two clamping strips 211 in each group of clamping members 210 to move away from each other and open (release the items to be unloaded), and the driving ends of the first driving member 220 and the second driving member 230 are retracted to drive the two clamping strips 211 in each group of clamping members 210 to move closer to each other and clamp the items to be unloaded.

[0041] By the same token, the third driving member 330 and the fourth driving member 340 are arranged opposite to each other, that is, the driving ends of the third driving member 330 and the fourth driving member 340 are extended to drive the first hook rack 310 and the second hook rack 320 to move away from each other and open (release the tray 20), and the driving ends of the third driving member 330 and the fourth driving member 340 are retracted to drive the first hook rack 310 and the second hook rack 320 to move closer to each other and clamp the tray 20.

[0042] Further, the hanger assembly 100 includes a hanger plate 110 and a frame 120. The hanger plate 110 can be hung on the robot arm. The frame 120 is hung on the bottom of the hanger plate 110. The clamping member 210, the first driving member 220 and the second driving member 230 are all hung on the frame 120. The first hook frame 310 and the second hook frame 320 are hung on both ends of the hanger plate 110 along the first direction. The third driving member 330 and the fourth driving member 340 are both located on the hanger plate 110. The frame 120 is used to hang the clamping assembly 200. The third driving member 330 and the fourth driving member 340 are supported and placed on the hanger plate 110. The first hook frame 310 and the second hook frame 320 are located at both ends of the hanger plate 110 and are respectively drooped on both sides of the entire layer of unloaded products, which does not affect the clamping assembly 200 to clamp the unloaded products.

[0043] It should be noted that the hanging plate 110 and the frame 120 are stacked at intervals, and the two ends along the first direction are connected by a fixing plate.

[0044] Optionally, the hanger assembly 100 further includes a base 130 , which is located on the hanger plate 110 , and the base 130 can be hung on a robotic arm.

[0045] In this embodiment, the hanging plate 110 includes three flat plates, which are arranged in sequence along the first direction. The base 130 is located on the middle flat plate, and the third driving member 330 and the fourth driving member 340 are respectively located on the two flat plates at both ends.

[0046] Optionally, continue as Figure 2 As shown, the clamping assembly 200 further includes a first guide shaft 260 , both ends of which are respectively fixed to the frame 120 , and the clamping strips 211 are slidably connected to the guide shafts to guide the sliding of the clamping strips 211 .

[0047] In this embodiment, both ends of the first guide shaft 260 along the first direction are sequentially penetrated by the frame 120 and the fixing plate and connected to the first fixing block at the corresponding end.

[0048] Furthermore, the clamping assembly 200 also includes a plurality of first linear bearing seats 270, each of which is fixed on a corresponding clamping strip 211, and the first guide shaft 260 slides through all the first linear bearing seats 270, and a sliding connection between the clamping strip 211 and the first guide shaft 260 is achieved through the first linear bearing seat 270, with a simple structure and simple installation and operation.

[0049] In this embodiment, the clamping assembly 200 includes two first guide shafts 260, and the two first guide shafts 260 are arranged at intervals along the second direction. The first driving member 220 and the second driving member 230 are located between the two first guide shafts 260, thereby improving the sliding guiding effect on the excessively long clamping strip 211.

[0050] Optionally, the first connector includes a plurality of first connector plates 240, which are sequentially arranged along the first direction, and each first connector plate 240 connects two adjacent odd-numbered clamping strips 211; the second connector includes a plurality of second connector plates 250, which are sequentially arranged along the first direction, and each second connector plate 250 connects two adjacent even-numbered clamping strips 211. The first connector and the second connector are respectively composed of a plurality of first connector plates 240 and a plurality of second connector plates 250, so that the number of the first connector plates 240 and the second connector plates 250 can be increased or decreased according to the number of the clamping strips 211.

[0051] Furthermore, multiple first connecting plates 240 are staggered above and below the clamping member 210; multiple second connecting plates 250 are staggered above and below the clamping member 210 to avoid the width of the clamping strip 211 being too narrow, so that two first connecting plates 240 or two second connecting plates 250 cannot be connected to the same clamping strip 211.

[0052] Optionally, continue as Figure 1 , Figure 3 and Figure 5 As shown, the hook stacking assembly 300 also includes a second guide shaft 350, which is fixed to the hanging plate 110 along the first direction. The first hook rack 310 and the second hook rack 320 are both slidably disposed on the second guide shaft 350, which guides the sliding of the first hook rack 310 and the second hook rack 320.

[0053] Furthermore, the hook stack assembly 300 also includes a second linear bearing seat 360, which is fixed to the hanging plate 110, and the second guide shaft 350 slides through the second linear bearing seat 360. The first hook frame 310 and the second hook frame 320 are slidably connected to the second guide shaft 350 through the second linear bearing seat 360, and the structure is simple and the installation operation is simple.

[0054] In this embodiment, two groups of second guide shafts 350 are provided. The two groups of second guide shafts 350 are spaced apart along the second direction. The third driving member 330 and the fourth driving member 340 are located between the two groups of second guide shafts 350 .

[0055] Optionally, hooks are provided on the inner sides of the first hook rack 310 and the second hook rack 320 , and the hooks can be hooked on the grooves on both sides of the tray 20 .

[0056] It should be noted that the number of hooks on the first hook rack 310 and the second hook rack 320 corresponds to the number of grooves on the corresponding side of the tray 20 .
