Description

Technical Field

[0001] The utility model belongs to the technical field of assembly equipment, in particular to a clamping mechanism and workpiece assembly equipment. Background Art

[0002] Workpiece assembly equipment is a common automated or semi-automated equipment used to assemble individual workpieces into products. The workpiece assembly equipment includes a feeding device installed on a frame. The feeding device generally includes a hopper and a feeding mechanism. The driving component in the feeding mechanism is often a cylinder structure. The cylinder structure must be connected to the air source through a detachable ventilation pipe, so that the cylinder structure can provide kinetic energy for the feeding mechanism to achieve automated or semi-automated feeding. When the feeding device includes multiple groups of hoppers and feeding mechanisms, the cylinder structures in each feeding mechanism must be connected to the air source through a ventilation pipe respectively. Once the feeding device needs to be disassembled, replaced, or repaired, each cylinder structure must be connected or disassembled to the corresponding ventilation pipe, and then the feeding mechanism must be removed from the frame. When there are a large number of feeding mechanisms on the feeding device, the disassembly steps will be particularly cumbersome (the same is true for the installation steps) and the efficiency is low.

[0030] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0031] like Figures 1 to 3 As shown, the workpiece assembly equipment in one embodiment of the present invention includes a frame 1, a feeding device 2 and a clamping mechanism 3; the frame 1 includes an air supply unit 11, the air supply unit 11 includes an air supply cavity 111, and the air supply cavity 111 is connected to the air source; the feeding device 2 includes a plurality of cylinders 21 and a connecting member 22 connected to the plurality of cylinders 21, and the connecting member 22 is provided with a plurality of connecting cavities (not shown in the figure) that correspond one-to-one to and are connected to the plurality of cylinders 21; the clamping mechanism 3 includes a clamping member 31 and a driver 32, the clamping member 31 includes a clamping portion 311 for clamping the connecting member 22; the driver 32 includes a connected fixed end 321 and an output end 322, one of the fixed end 321 and the output end 322 is connected to the clamping member 31, and the other is connected to the air supply unit 11, and the clamping mechanism 3 can drive the connecting cavity of the connecting member 22 to be connected or separated with the air supply cavity 111 of the air supply unit 11.

[0032] It can be understood that the connection between the air source and the air supply unit 11 on the frame 1 can be a conventional pipeline connection, that is, the air source is connected to the air supply unit 11 through a pipeline. The present invention adopts a connection method in which the air source is connected to the air supply unit 11 on the frame 1, and the air supply unit 11 is further connected to the connecting piece 22 of the cylinder 21, thereby avoiding the direct connection method between the pipeline and the connecting piece 22 of the cylinder 21. This avoids the steps of connecting and disconnecting multiple pipelines with the connecting pieces 22 of multiple cylinders 21 one by one during the installation and removal steps of the feeding device 2. The clamping mechanism 3 can control the unified connection and disconnection of the multiple connecting pieces 22 with the air supply unit 11, thereby realizing the rapid connection and disconnection of the feeding device 2 and the air supply unit 11. The cylinder 21 is the power source of the feeding device 2.

[0033] Specifically, in this embodiment, the actuator 32 is a cylinder 21, the fixed end 321 is a cylinder body, and the output end 322 is a piston rod. That is, the cylinder 21 can drive the clamping member 31 to move toward or away from the air supply unit 11. The clamping member 31 is connected to the connector, thereby driving the connecting cavity of the connector 22 to connect or disconnect with the air supply cavity 111 of the air supply unit 11. In other embodiments, the actuator 32 can be a common drive structure such as an electric cylinder or servo motor, as well as a corresponding connecting structure.

[0034] In the embodiment shown in the figure, the output end 322 is fixedly connected or detachably connected to the air supply unit 11 , and the fixed end 321 is fixedly connected or detachably connected to the clamping member 31 .

[0035] Preferably, the clamping member 31 includes two spaced apart clamping portions 311. The spaced apart clamping portions 311 can improve the stability of the connection between the clamping member 31 and the connecting member 22.

[0036] like Figure 2 and 3 As shown, the clamping member 31 includes a connecting portion 312. The clamping portions 311 are disposed on opposite sides of the connecting portion 312, and one of the fixed end 321 and the output end 322 is connected to the connecting portion 312. The relative arrangement can clamp the connecting member 22 from opposite sides of the connecting member 22, thereby improving the stability of the connection between the clamping member 31 and the connecting member 22.

[0037] The connecting portion 312 may be provided with a guide hole 3121 , and the air supply unit 11 may be provided with a guide post 112 . The guide post 112 is slidably connected to the guide hole 3121 , thereby limiting the movement direction of the clamping member 31 .

[0038] Specifically, the clamping portion 311 has a clamping slot 3111 extending therethrough. The connector 22 can be inserted into or removed from the clamping slot 3111 in the direction of the clamping slot 3111. In this embodiment, the movement direction of the clamping member 31 is perpendicular to the direction of the clamping slot 3111. In other embodiments, the movement direction of the clamping member 31 is in the same direction as the direction of the clamping slot 3111, or at an angle thereto.

[0039] In one embodiment, the clamping groove 3111 has a first surface 3112 and a second surface 3113 opposite to each other, and the connector 22 is clamped between the first surface 3112 and the second surface 3113. That is, when the clamping groove 3111 clamps the connector 22, the first surface 3112 and the second surface 3113 are tightly against the connector 22.

[0040] In a specific embodiment, the clamping groove 3111 has a first surface 3112 and a second surface 3113 that are arranged opposite to each other. The clamping groove 3111 and the connecting member 22 are clearance-fitted. In the first state, the connecting member 22 is clamped between the first surface 3112 and the air supply unit 11, and the communicating cavity is connected to the air supply cavity 111. The clearance-fitting between the clamping groove 3111 and the connecting member 22 can be understood as meaning that in the first state, the first surface 3112 abuts against the connecting member 22 and cooperates with the air supply unit 11 to clamp the connecting member 22, while the second surface 3113 is separated from the connecting member 22. In addition, after the connecting member 22 is separated from the air supply unit 11, the clearance fit facilitates the separation of the connecting member 22 from the clamping groove 3111.

[0041] Furthermore, in the second state, the second surface 3113 abuts against the connecting member 22, and the communicating cavity is separated from the air supply cavity 111. It is understandable that the driver 32 drives the clamping member 31 to move, thereby achieving the switching of the clamping member 31 between the first state and the second state. That is, when the feeding device 2 needs to be separated from the frame 1, the driver 32 drives the clamping member 31 to move, the second surface 3113 abuts against the connecting member 22, and drives the connecting member 22 away from the air supply unit 11, thereby achieving the separation of the feeding device 2 from the frame 1.

[0042] like Figures 3-5 As shown, the connecting member 22 is provided with a plurality of connecting protrusions 23, each of which is provided with a communicating hole corresponding to a communicating cavity. The air supply unit 11 is provided with a communicating hole corresponding to an air supply cavity 111, and the air supply cavity 111 is provided through the air supply unit 11. The clamping mechanism 3 can drive the connecting protrusions 23 to be connected or separated with the air supply cavity 111, so that the communicating cavity is connected or separated with the air supply cavity 111. That is, the air supply cavity 111 can be considered as an air supply hole.

[0043] It is understood that the air supply cavity 111 and the connecting protrusion 23 can be sealed to ensure airtightness after the connecting cavity and the air supply cavity 111 are connected. The insertion direction of the connecting protrusion 23 and the air supply cavity 111 can be considered as the movement direction of the clamping member 31. One end of the air supply cavity 111 along its through-line direction can be connected to the connecting protrusion 23, and the other end is provided with a connector 113 connected to the air source pipeline.

[0044] The steps for installing the feeding device 2 on the frame 1 in the workpiece assembly equipment of the present invention are: inserting the connecting piece 22 of the feeding device 2 into the clamping groove 3111 along the penetration direction of the clamping groove 3111, and then starting the driver 32, and the first surface 3112 of the clamping groove 3111 drives the connecting piece 22 close to the air supply unit 11 until the connecting protrusion 23 on the connecting piece 22 is plugged into the air supply hole of the air supply unit 11, and the connecting piece 22 is clamped between the first surface 3112 and the second surface 3113 or the connecting piece 22 is clamped between the first surface 3112 and the air supply unit 11, and the steps for installing the feeding device 2 on the frame 1 are completed.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0046] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
