Description

Technical Field

[0001] The utility model relates to the technical field of tooling fixtures, in particular to a ceramic substrate clamping mechanism. Background Art

[0002] Ceramic substrates are widely used in various circuits and microwave devices due to their high precision, stability, good thermal conductivity, low thermal resistance, and compact size. During processing, chips need to be bonded to designated locations on the ceramic substrate. After processing, the chips on the ceramic substrate need to be inspected. During both the processing and inspection processes, the ceramic substrate needs to be clamped with a fixture to ensure stability during processing.

[0003] The existing clamp includes two clamping blocks and a driving device. The ceramic substrate is placed between the two clamping blocks. The driving device drives the two clamping blocks to move closer to each other to clamp the ceramic substrate.

[0004] However, the thickness of the ceramic substrate is generally relatively thin. During the clamping process, the clamping force exerted by the two clamping blocks on both sides of the ceramic substrate is difficult to control. If the clamping force exerted by the two clamping blocks on both sides of the ceramic substrate is too large, the ceramic substrate may be bent or damaged. If the clamping force exerted by the two clamping blocks on both sides of the ceramic substrate is too small, the ceramic substrate may not be clamped tightly. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0025] Reference Figure 1 and Figure 2An example of the present invention provides a ceramic substrate clamping mechanism, including a base 100, a first clamping block 200, a second clamping block 300, a first driving member 400 and a second driving member 500, the first clamping block 200 and the second clamping block 300 being arranged opposite to each other, a clamping station being formed between the first clamping block 200 and the second clamping block 300, the first driving member 400 being used to drive the first clamping block 200 to approach or move away from the second clamping block 300, the second driving member 500 being used to drive the second clamping block 300 to approach or move away from the first clamping block 200, an elastic component 600 being arranged between the first driving member 400 and the first clamping block 200, the elastic component 600 being used to buffer the clamping force of the first clamping block 200 acting on the side of the ceramic substrate.

[0026] During operation, the ceramic substrate is placed on the clamping station, and the first driving member 400 and the second driving member 500 respectively drive the first clamping block 200 and the second clamping block 300 to approach each other to clamp the ceramic substrate. The elastic component 600 arranged between the first driving member 400 and the first clamping block 200 can buffer the clamping force of the first clamping block 200 on the side of the ceramic substrate. On the one hand, it can prevent the clamping force of the first clamping block 200 and the second clamping block 300 on both sides of the ceramic substrate from being too large. On the other hand, the elastic component 600 can also provide elastic force, which acts on the first clamping block 200 to ensure that the clamping force of the first clamping block 200 and the second clamping block 300 on both sides of the ceramic substrate is appropriate, thereby ensuring that the ceramic substrate is clamped without being damaged.

[0027] Reference Figure 3 In some preferred embodiments, the elastic component 600 includes a connecting block 610 and a spring 620, the two ends of the spring 620 are respectively connected to the connecting block 610 and one side of the first clamping block 200, and the output end of the first driving member 400 is connected to the connecting block 610.

[0028] It can be understood that, during the process of the first driving member 400 and the second driving member 500 respectively driving the first clamping block 200 and the second clamping block 300 to approach each other, after the first clamping block 200 and the second clamping block 300 respectively abut against the two sides of the ceramic substrate, at this time, the first driving member 400 continues to drive the connecting block 610 to move, the first clamping block 200 stops moving, and the spring 620 is compressed. At the same time, the elastic force of the spring 620 acts on the first clamping block 200, so that the first clamping block 200 and the second clamping block 300 clamp the ceramic substrate.

[0029] Furthermore, a guide column 630 is provided on the connecting block 610, and a guide hole 210 is provided on the first clamping block 200. The guide column 630 slides with the guide hole 210, and the spring 620 is sleeved on the guide column 630. The length direction of the guide column 630 extends along the moving direction of the first clamping block 200. During the compression of the spring 620, the connecting block 610 drives the guide column 630 to slide along the guide hole 210, thereby preventing the first clamping block 200 from shaking and ensuring stability during clamping.

[0030] Furthermore, a first countersunk hole 611 is provided on one side of the connecting block 610, and a second countersunk hole 220 is provided on one side of the first clamping block 200. The first countersunk hole 611 is coaxial with the guide column 630, and the second countersunk hole 220 is coaxial with the guide hole 210. The second countersunk hole 220 and the guide hole 210 form a stepped hole. The first countersunk hole 611 and the second countersunk hole 220 respectively limit the two ends of the spring 620, thereby preventing the spring 620 from radial displacement. Moreover, there is no need to fix the two ends of the spring 620 to the sides of the connecting block 610 and the first clamping block 200 respectively, which facilitates installation and disassembly.

[0031] Reference Figure 1 and Figure 4 In some preferred embodiments, two guide blocks 700 are provided on the base 100. The two guide blocks 700 are respectively located on both sides of the first clamping block 200. The two guide blocks 700 respectively guide the two sides of the first clamping block 200, thereby improving the stability of the first clamping block 200 during movement and ensuring that the clamping surface of the first clamping block 200 is parallel to the side of the ceramic substrate.

[0032] Specifically, the guide block 700 is provided with a guide groove 710, and flanges 230 are provided on both sides of the first clamping block 200. The flanges 230 slide in conjunction with the guide grooves 710. The guide grooves 710 can limit the top of the flanges 230, further improving the stability of the first clamping block 200 during movement.

[0033] In some preferred embodiments, a clamping slope 240 is provided on the opposite side of the first clamping block 200 and the second clamping block 300. The two clamping slopes 240 and the base 100 form a dovetail-shaped clamping space. When the first clamping block 200 and the second clamping block 300 are clamping the ceramic substrate, the two clamping slopes 240 can limit the top of the ceramic substrate, thereby preventing the ceramic substrate from warping and ensuring the stability of the ceramic substrate when clamping.

[0034] In some preferred embodiments, a positioning column 800 is provided on the base 100, and a positioning groove 310 is provided on the side of the second clamping block 300 close to the first clamping block 200, and the positioning groove 310 corresponds to the positioning column 800. When the second driving member 500 drives the second clamping block 300 close to the first clamping block 200, the positioning groove 310 abuts against the positioning column 800, which can limit the second clamping block 300 and ensure the consistency of the position of the ceramic substrate. Moreover, the positioning column 800 is located in the positioning groove 310 and will not affect the contact between the second clamping block 300 and the side of the ceramic substrate.

[0035] Furthermore, a linear guide rail 900 is provided between the base 100 and the second clamping block 300 . The linear guide rail 900 can guide the second clamping block 300 , thereby improving the stability of the second clamping block 300 during movement.

[0036] In some preferred embodiments, the first driving member 400 and the second driving member 500 are both cylinders, which have a simple structure, are easy to install, and have low cost.

[0037] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
