DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0024] Example

[0025] like Figures 1 to 4 As shown, an adaptive sheet clamp is used for clamping a sheet 100, comprising: a horizontal substrate 1 and a cylinder 2 arranged above the horizontal substrate 1. A push block 3 located below the horizontal substrate is installed at the lower end of the piston rod of the cylinder 2. Specifically, the piston rod of the cylinder 2 and the push block 3 are connected by a connecting rod 8. The lower end of the connecting rod 8, whose upper end is connected to the piston rod of the cylinder 2, passes through the horizontal substrate 1 and is connected to the push block 3. The push block 3 can move in the vertical direction with the piston rod of the cylinder 2. The lower surface of the horizontal substrate 1 is provided with a plurality of telescopic sliders 4 that are opposite to each other. The plurality of telescopic sliders 4 are arranged around the push block 3 and are arranged at equal intervals in the circumferential direction. A clamping bar 5 for clamping and contacting the sheet 100 is installed on the lower surface of each telescopic slider 4 at one end away from the push block 3.

[0026] Each of the telescopic sliders 4 is movably mounted on the horizontal base plate 1 through a movable block 9. A guide block 10 is fixedly mounted on the lower surface of the horizontal base plate and on the side of each movable block 9 opposite to the push block 3. At least one guide rod 111 is arranged between each guide block 10 and the corresponding movable block 9. One end of the guide rod 111 arranged along the moving direction of the telescopic slider 4 is connected to the guide block 10. The other end of the guide rod 111 is slidably matched with the movable block 9 through a guide sleeve 112. The movable block 9 spans across the telescopic slider 4, and the two are an integrated structure. Under the guidance of the guide rod 111, each of the telescopic sliders 4 can reciprocate along the radial direction in which it is located. In order to achieve more stable clamping, in addition to arranging the clamping strip 5 on the telescopic slider 4, the clamping strip 5 can also be arranged at both ends of the movable block 9 to stably clamp the sheet in the length and width directions.

[0027] Several main slope surfaces 31 corresponding to the telescopic slider 4 are formed on the outer side of the lower end of the push block 3, and a secondary slope surface 45 matching the corresponding main slope surface 31 is formed on the end of each telescopic slider 4 close to the push block 3, and the lower end of the secondary slope surface 45 corresponding to the main slope surface 31 located above it extends toward the direction close to the push block 3.

[0028] A connecting pin 6 is installed on the lower surface of each telescopic slider 4, and the distance between each connecting pin 6 and the push block 3 is equal. An elastic belt 7 is sleeved and connected between several connecting pins 6 and is in a tensioned state.

[0029] In this embodiment, two guide rods 111 are disposed between each guide block 10 and the corresponding movable block 9 , and the two guide rods 111 are respectively located on both sides of the corresponding telescopic sliding block 4 .

[0030] In this embodiment, a stop block 12 is provided on the lower surface of the horizontal substrate 1 and on the side of each movable block 9 opposite to the guide block 10. When the stop block 12 is in surface contact with the movable block 9, the clamping bar 5 is in clamping contact with the sheet 100.

[0031] In this embodiment, the horizontal portion 51 of the clamping bar 5 is mounted on the telescopic slider 4 , and the lower end of the vertical portion 52 of the clamping bar 5 has a bent portion 53 extending toward the push block 3 .

[0032] In this embodiment, four telescopic sliders 4 are provided, namely a left telescopic slider 41 , a right telescopic slider 42 , a front telescopic slider 43 , and a rear telescopic slider 44 , which are provided correspondingly.

[0033] In this embodiment, the outer side surface of the lower end of the push block 3 is a tapered surface.

[0034] In this embodiment, the elastic belt 7 is a circular rubber ring.

[0035] In this embodiment, the material piece 100 is a metal lead frame.

[0036] The working principle of the utility model is as follows:

[0037] When in use, the cylinder 2 drives the connecting rod 8 to drive the push block 3 to move downward, and the push block 3 synchronously drives the two opposite telescopic sliders 4 to move away from each other so that the distance between the two opposite clamping bars 5 is maximized and each clamping bar 5 moves to the outside of the sheet 100 to be transported accordingly;

[0038] Next, the cylinder 2 drives the connecting rod 8 to drive the push block 3 to move upward until the secondary slope surface 45 is no longer in contact with the main slope surface 45 on the telescopic slider 4. During this process, each telescopic slider 4 moves synchronously toward the sheet 100 under the action of the elastic belt 7 until the two opposing clamping bars 5 clamp the sheet 100.

[0039] In the above process, the up and down movement of the push block 3 and the tensioning and contraction of the elastic belt 7 synchronously drive the telescopic sliders 4 opposite to each other to move closer or farther away from each other, thereby realizing the synchronous centering, clamping and loosening of the material 100 by the clamping strips 5 installed on the telescopic sliders 4, which not only facilitates the taking and placing of the material 100, but also can calibrate the position of the material 100 in at least one direction while clamping, and can also realize elastic clamping of the material and avoid damage caused by excessive force on one side of the material.

[0040] When the telescopic sliders 4 are moving toward or away from each other, the guide rods 111 and guide sleeves 112 cooperate to ensure the consistency of the long-term reciprocating motion of the telescopic sliders 4 driven by the movable block 9, thereby avoiding the position deviation of the telescopic sliders 4.

[0041] When the above-mentioned adaptive material clamp is used, the upward and downward movement of the push block 3 and the tensioning and contraction of the elastic belt 7 are synchronously driven to drive the telescopic sliders 4 opposite to each other to approach or move away from each other. The setting of the guide rod 111 and the guide sleeve 112 ensures the consistency of the long-term reciprocating motion of the telescopic slider 4 driven by the movable block 9, thereby avoiding the position deviation of the telescopic slider 4, thereby realizing the synchronous centering clamping and loosening of the material by the clamping bar 5 installed on the telescopic slider 4 and ensuring the stability and consistency of the surface contact between the clamping bar and the material, which is convenient for taking and placing the material, and can calibrate the position of the material in at least one direction while clamping it, and can also realize the elastic clamping of the material and avoid damage caused by excessive force on one side of the material.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
