Fig. 1 shows a schematic structural diagram of a clamp provided by an embodiment of the present invention. As shown in fig. 1, the jig includes a support 1 and at least one moving jig assembly 2 provided on the support 1. Each moving gripper assembly 2 comprises a drive mechanism 20 and a moving gripper mechanism 21. The driving mechanism 20 is used for driving the movable clamping mechanism 21 to do reciprocating linear motion.
Referring to fig. 1, the support member 1 is a platform for supporting at least one movable clamp assembly 2, and therefore, the support member 1 is required to have certain strength and rigidity to meet the requirement of supporting at least one movable clamp assembly 2. The specific material of the supporting member 1 is not limited, and for example, the supporting member may be a metal supporting member or a non-metal supporting member having certain strength and rigidity.
The form of the above-mentioned supporting member 1 is various in structural terms, and is not particularly limited herein.
As an example, referring to fig. 1, the support 1 may be a support plate having opposite first and second ends. The drive mechanism 20 included in the moving clamp assembly 2 may be fixed to the support plate and the moving clamp mechanism 21 may be disposed in the region of the support plate between the first and second ends. The movable clamping mechanism 21 can move from the first end to the second end or from the second end to the first end with a straight line as a motion track under the driving of the driving mechanism 20. In order to reduce the weight of the whole clamp, a plurality of lightening holes can be formed through the supporting plate. The opening positions and the number of the lightening holes and the size of each lightening hole are not particularly limited under the condition of ensuring that the support plate has enough support force for the movable clamp assembly 2. It should be understood that the shape of the support plate is various, for example, the support plate may be a square support plate, a triangular support plate, a trapezoidal support plate, or a shaped support plate. The irregular support plate refers to the irregular support plate which has an irregular outer contour, or the irregular support plate can comprise a curved surface section and/or a plane section, and the like, and the curved surface section and/or the plane section form the irregular outer contour.
As another example, referring to fig. 1, the supporting member 1 may be a supporting frame, and the supporting frame may be an annular supporting frame formed by surrounding a plurality of supporting rods. It should be understood that the annular support frame is an annular support frame in a broad sense, and may specifically be a square support frame, a triangular support frame, a trapezoidal support frame, or a special-shaped support frame (the special-shaped support frame refers to a support frame with an irregular outer contour). The arrangement of the movable clamp assembly 2 on the support frame may refer to the arrangement of the movable clamp assembly 2 on the support plate, which is not described herein again.
In practical application, referring to fig. 1, the supporting member 1 carrying the movable clamp assembly 2 can be detachably or firmly connected to a robot arm, and the whole clamp is driven by the robot arm to move. For example, the clamp can move in the directions of an X axis, a Y axis or a Z axis under the driving of the manipulator. In the case that the manipulator drives the whole clamp to move, the driving mechanism 20 included in the movable clamp assembly 2 can also drive the movable clamping mechanism 21 to make a reciprocating linear motion. That is, the clamp can be moved to a predetermined area (the predetermined area may be above an area where the workpiece is to be clamped, or above an area where the workpiece is to be mounted, etc.) by the manipulator. After the clamp reaches the preset area, the driving mechanism 20 can be used to drive the movable clamping mechanism 21 to make a reciprocating linear motion, so that the movable clamping mechanism 21 can accurately move to a preset position (the preset position can be directly above the workpiece to be clamped, or directly above the workpiece mounting position). At this moment, the manipulator can be continuously controlled to drive the clamp to integrally move downwards so as to realize accurate grabbing or accurate releasing of the workpiece.
The following takes the assembly of the lamp strip of the lcd tv as an example to illustrate the application process of the clamp, and it should be understood that the following examples are only for explanation and not for limitation.

When a set of lamp strip includes the lamp strip of many interval placements, can set up the removal anchor clamps subassembly 2 that equals with lamp strip quantity on the anchor clamps. The gripper can be moved and temporarily stopped above the tray, for example by a robot. At this time, the driving mechanism 20 drives the plurality of movable clamping mechanisms 21 to move, so that one movable clamping mechanism 21 corresponds to a position right above each light bar. Under the drive of manipulator, anchor clamps move to the direction that is close to the lamp strip until each removes fixture 21 and all corresponds a lamp strip of centre gripping. So far, the clamp finishes the clamping operation of the lamp strip.
Referring to fig. 1, after the clamp finishes clamping the light bar, and when the transmission line has a back plate (generally, the mounting position of the light bar is marked on the back plate), the clamp is driven by the manipulator to move to the upper side of the back plate. At this time, the driving mechanism 20 drives the plurality of movable clamping mechanisms 21 to move, so that one movable clamping mechanism 21 corresponds to a position right above the installation position of each light bar on the back plate (the light bar is clamped on the movable clamping mechanism 21).
