Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of semiconductor devices, and particularly relates to a chip clamping device with a planar linkage structure. BACKGROUND

[0002] In the process of semiconductor chip manufacturing and packaging, clamping and transferring of various components are always involved. The commonly used clamping and transferring methods include tweezers clamping and vacuum adsorption. Among them, tweezers clamping is the most common form adopted by technicians due to its simplicity and convenience. However, when clamping components, especially fragile chips, the tweezers often make line contact with the side of the components, rather than parallel contact, as shown in FIG. 1, and since the clamping force is controlled by humans, it is greatly affected by the proficiency of the personnel, so the components are often damaged. Figure 1 SUMMARY

[0003] (I) Technical problem to be solved

[0004] The present application proposes a chip clamping device with a planar linkage structure to solve the technical problem of changing the line contact mode of the existing tweezers clamping and avoiding damage to components.

[0005] (II) Technical solution

[0006] In order to solve the above technical problems, the present application proposes a chip clamping device with a planar linkage structure, which comprises a device housing, a clamping head, a planar linkage structure, a button, a spring and an adjusting screw. The clamping head with parallel clamping parts is arranged at the front end of the device housing, a plurality of planar linkage structures are fixed on the inner wall of the front end of the device housing, the rear end of the clamping head is connected with the front end vertex of the planar linkage structure, and the planar linkage structure keeps the two clamping parts of the clamping head in a parallel state. The adjusting screw is fixed at the rear end of the device housing, the spring is arranged inside the device housing, the front and rear ends of the spring are connected with the planar linkage structure and the adjusting screw through a pull rod, so that the spring is always in a tension state and provides clamping force for the clamping head through the planar linkage structure. The button is installed on the side wall of the device housing, the front end of the button extends into the interior of the device housing, and the button can press and tension the pull rod connected between the spring and the planar linkage structure. When the button is pressed, the pull rod pushes the planar linkage structure forward, so that the planar linkage structure deforms and compresses, driving the two clamping parts of the clamping head to open, and the reset force of the button upward is increased by the tension force of the spring. When the button is released, the button is automatically lifted upward and reset under the action of the spring, the tensioned spring pulls the planar linkage structure backward, driving the two clamping parts of the clamping head to close, and clamping the components.

[0007] ​Further, the planar linkage structure is a parallelogram, the planar linkage structure is fixed on the inner wall of the front end of the device shell through the side, and the front end of the spring is connected with the bottom side of the planar linkage structure through the pull rod.

[0008] (III) Beneficial Effects

[0009] The planar linkage structure chip clamping device provided by the application comprises a device shell, a replaceable clamping head, a planar linkage structure, a button, a spring and an adjusting screw. The device adopts the planar linkage structure of a parallelogram, so that the clamping part of the clamping head is always in a parallel posture, the contact area when contacting the component is surface contact, and the contact pressure can be reduced. The clamping force of the component is only affected by the tension degree of the spring, the clamping force is stable, and the chip will not be damaged due to poor proficiency of the user. The tension degree of the spring can be changed through the adjusting screw, so that the clamping force of the clamping head can be changed. Different clamping heads with different structures can be replaced according to the sizes of different components, and the device has the characteristics of compact structure, reliability, strong component specification adaptability and the like.

[0015] In order to make the purpose, content and advantages of the application more clear, the specific implementation of the application will be further described in combination with the drawings and embodiments.

[0016] The embodiment of the application provides a planar linkage structure chip clamping device, and the structure is shown in the figure. Figure 2 The whole device appearance and size are similar to those of an ordinary ball pen, and mainly comprise a device shell 5, a replaceable clamping head 2, a planar linkage structure 3, a button 4, a spring 6 and an adjusting screw 7.

[0017] The clamping head 2 with parallel clamping parts is arranged at the front end of the device housing 5, a plurality of parallelogram plane link structures 3 are fixed on the inner wall of the front end of the device housing 5 through the side, the rear end of the clamping head 2 is connected with the front end vertex of the plane link structure 3, and the parallelogram plane link structure 3 can keep the two clamping parts of the clamping head 2 in parallel state at all times, as shown in Figure 3 .

[0018] The adjusting screw 7 is fixed at the rear end of the device housing 5, the spring 6 is arranged in the interior of the device housing 5, the front and rear ends of the spring 6 are connected with the bottom edge of the plane link structure 3 and the adjusting screw 7 through the pull rod respectively, so that the spring 6 is always in tension state, and the plane link structure 3 provides clamping force for the clamping head 2. By changing the length of the adjusting screw 7 in the interior of the device housing 5, the tension degree of the spring 6 can be changed, and then the clamping force of the clamping head 2 is changed.

[0019] The button 4 is installed on the side wall of the device housing 5, the front end of the button 4 extends into the interior of the device housing 5, and the button 4 can press and tension the pull rod connected between the spring 6 and the plane link structure 3. As shown in Figure 4 , when the button 4 is pressed, the pull rod pushes the plane link structure 3 forward, so that the plane link structure 3 is deformed and compressed, and then drives the two clamping parts of the clamping head 2 to open, at this time, the reset force of the button 4 upward is increased by the tension force of the spring 6. When the button 4 is released, the button 4 is automatically lifted upward and reset under the action of the spring 6, the spring 6 in tension pulls the plane link structure 3 backward, and then drives the two clamping parts of the clamping head 2 to close tightly, so that the clamping of the component 1 is realized.

[0020] Since the opening and closing range of the plane link structure 3 is limited, according to the size of the clamped component, the chip clamping device of the application can replace the corresponding specification of the clamping head 2, as shown in Figure 5 .

[0021] The above only describes the preferred embodiments of the application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the application, a number of improvements and modifications can be made, and these improvements and modifications should be considered as the protection scope of the application.
