Detailed Description

The present application is described in further detail below with reference to the accompanying drawings.

Referring to fig. 1, an embodiment of the present application discloses a suction cup device for sucking a special-shaped member. Referring to fig. 1, a suction cup device for sucking a profile includes a support assembly 100 fixedly provided to a free end of a transfer device, a plurality of suction cup assemblies 200 for sucking a profile surface, and a pneumatic element 300 for controlling the plurality of suction cup assemblies 200 to perform vacuum suction.

Referring to fig. 1, the chuck assembly 200 includes a guide shaft sleeve 210 fixedly disposed at the bottom of the support assembly 100, a hollow slide rod 220 coaxially slidably disposed in the guide shaft sleeve 210, a vacuum chuck 230 fixedly disposed at the bottom end of the hollow slide rod 220, and an abutment spring 240 coaxially sleeved on the outer peripheral wall of the hollow slide rod 220, wherein the abutment spring 240 is disposed between the guide shaft sleeve 210 and the vacuum chuck 230 in an abutting manner. When the pneumatic element 300 controls the sucker assembly 200 to perform vacuum adsorption, the bottom end of the hollow sliding rod 220 is stressed and slides upwards into the guide shaft sleeve 210, so that the abutting springs 240 abutting between the guide shaft sleeve 210 and the vacuum sucker 230 generate compression deformation, and the different elastic variables of the abutting springs 240 form the profiling of the adsorbed special-shaped surface of the workpiece, thereby realizing the adsorption of the special-shaped workpiece.

Referring to fig. 1 and 2, the abutment spring 240 is disposed around the outer peripheral wall of the hollow slide bar 220, and the guide sleeve 210 provides a guide supporting force for sliding of the hollow slide bar 220, so that the hollow slide bar 220 is not deviated, and the vacuum chuck 230 is positioned, buffered and adsorbed on the profiled surface, and has a higher lateral adsorption force. Meanwhile, the height of the hollow sliding rod 220 and the length of the abutting spring 240 can be overlapped according to the maximum height difference of the adsorbed surface of the workpiece, so that the adsorption positioning accuracy is guaranteed, the overall universality is improved, and the problem that the overall universality is affected due to the fact that the elastic buffer height of the sucker cannot be overlapped due to the fact that the elastic change height of the sucker is inversely proportional to the adsorption accuracy in the related technical means is solved.

Referring to fig. 2, the plurality of chuck assemblies 200 are distributed in an array and the plurality of vacuum chucks 230 are at the same horizontal plane, so that the chuck device in the present application can not only adsorb a special-shaped workpiece, but also adsorb a workpiece with a horizontal surface on the adsorbed surface. The center distance between two adjacent rows of sucking disc assemblies 200 is equal to the disc diameter of the vacuum sucking disc 230, the structure is compact, and the workpiece can be contacted with the sucked surface to the greatest extent through the buffer of the abutting spring 240 to form profiling, so that the vacuum sucking disc assembly has good sucking stability. It should be noted that, the vacuum chuck 230 in the present application is preferably a flat chuck, and compared with chucks of other structures and shapes, the flat chuck is smaller in design and simple in process molding; the elastic variable is smaller due to smaller internal volume, so that the positioning accuracy and the grabbing efficiency are higher; meanwhile, the tray opening adopts a wide sealing opening, so that the adsorption stability is good.

Referring to fig. 1, the pneumatic component 300 includes a pneumatic control head 310 fixed on the top wall of the support assembly 100 and a control component (not shown) for controlling the pneumatic control head 310 to vacuumize, and the plurality of chuck assemblies 200 are synchronously communicated with the pneumatic control head 310 through a vacuum air passage for vacuum adsorption, so that the control component (not shown) can control the plurality of chuck assemblies 200 to simultaneously perform vacuum adsorption, thereby increasing the stability of the chuck device in the application during adsorption and being compatible with workpieces with large dead weights. It should be noted that the number of the air control heads 310 in the present application is two to increase the efficiency of vacuum pumping.

Referring to fig. 3, it is further explained that the inner wall of the support assembly 100 in the present application has a closed space 110, and the closed space 110 can form the vacuum air channel, so that the pneumatic element 300 can perform negative pressure vacuuming on the closed space 110 to achieve the effect of vacuum adsorbing the workpiece by the plurality of chuck assemblies 200, and an air pipe is not required to be connected between the chuck assemblies 200 and the pneumatic control head 310, thereby saving energy and improving the installation efficiency.

Referring to fig. 1 and 3, each guide sleeve 210 is coaxially and fixedly provided with a check valve 250 positioned in the closed space 110, and each check valve 250 is configured to allow air to enter the vacuum chuck 230 along the guide sleeve 210, thereby blocking the outside atmosphere from entering the support assembly 100 through the non-working chuck assembly 200 and breaking the vacuum negative pressure state of the closed space 110. The check valve 250 communicates with the guide sleeve 210 to form a sliding passage through which the hollow sliding rod 220 slides reciprocally, thereby further supporting the hollow sliding rod 220 to improve stability when the hollow sliding rod 220 slides, thereby improving overall adsorption accuracy. It should be noted that, in the working state, the hollow sliding rod 220 penetrates the opening and closing valve of the check valve 250 in the sliding channel.

When the vacuum chuck 230 contacts the workpiece to vacuum the workpiece, the hollow slide rod 220 slides upwards into the sliding channel, so that the vacuum chuck 230 is communicated with negative pressure gas in the closed space 110 through the opening and closing valve of the one-way valve 250 to adsorb the workpiece. When the surface area of the workpiece to be sucked is smaller than the suction area formed by the plurality of sucking disc assemblies 200, there are cases that a small part of the vacuum sucking discs 230 cannot contact the workpiece and do not work, but when the workpiece is sucked up by other normally working sucking disc assemblies 200, the non-working vacuum sucking discs 230 are elastically reset under the acting force of the abutting springs 240, so that the opening and closing valve of the one-way valve 250 connected with the non-working vacuum sucking discs 230 is normally closed, and the outside atmosphere is blocked from entering the closed space 110 at the position of the non-working vacuum sucking discs 230 to break the vacuum negative pressure state in the closed space 110. Therefore, when the workpiece is adsorbed to an area smaller than the vacuum adsorption area of the chuck device in the application, the workpiece can be adsorbed without dismantling the redundant chuck assembly 200, so that the overall universality is further improved.
