[0020] Figure 1 It is a schematic diagram of the overall structure of the T-shaped thimble group of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The T-shaped thimble group of the utility model will be described in more detail below with reference to the schematic diagrams, in which the preferred embodiments of the utility model are shown. It should be understood that those skilled in the art can modify the utility model described herein while still achieving the advantageous effects of the utility model. Therefore, the following description should be understood as a broad guidance for those skilled in the art and not as a limitation to the utility model.

[0022] In the following paragraphs, the utility model will be described more specifically by way of example with reference to the drawings. The advantages and features of the utility model will be clearer according to the following description. It should be noted that the drawings are all in a very simplified form and use non-precise scales, only for the purpose of conveniently and clearly assisting in explaining the purpose of the embodiments of the utility model.

[0023] As Figure 1 shown, an embodiment of the utility model provides a T-shaped thimble group, including a fixed base 1, a T-shaped thimble 2 and a thimble base 3.

[0024] Specifically, a plurality of hollow grooves 4 are provided through the fixed base 1, and the hollow grooves 4 are matched with the T-shaped thimble 2.

[0025] The T-shaped thimble 2 passes through the hollow groove 4, and the T-shaped thimble 2 is in close contact and sliding contact with the inner wall of the hollow groove 4.

[0026] The thimble base 3 is detachably arranged on the fixed base 1, and the thimble base 3 is used to support and fix the end of the T-shaped thimble 2.

[0027] In this embodiment, the number and distribution of the T-shaped thimbles 2 are determined according to the needs of chip soldering. The T-shaped thimbles 2 are inserted into the corresponding hollow grooves 4, and then the thimble base 3 is installed on the fixed base 1 to support and fix the ends of the T-shaped thimbles 2, completing the installation of the T-shaped thimbles 2.

[0028] Since the end of the T-shaped thimble 2 is fixed between the fixed base 1 and the thimble base 3, the T-shaped thimble 2 can be well fixed, effectively solving the problem of the T-shaped thimble 2 falling off. In addition, the T-shaped thimble 2 penetrates through the hollow groove 4, and the inner wall of the hollow groove 4 can support and fix the T-shaped thimble 2, effectively reducing the risk of the T-shaped thimble 2 skewing, and there is no need to correct the T-shaped thimble 2 during the installation process, saving the equipment modification time.

[0029] In a specific embodiment, the thimble base 3 and the fixed base 1 are detachably connected by bolts 5. When installing and fixing the thimble base 3, the bolts 5 are passed through the thimble base 3 and threadedly installed on the fixed base 1, and the installation of the T-shaped thimble 2 can be realized.

[0030] It should be noted that the installation between the thimble base 3 and the fixed base 1 is not limited to the installation of bolts 5, and can also be installed through other connecting parts, such as screw knobs.

[0031] Furthermore, the T-shaped thimble 2 includes a support base 21 and a thimble 22.

[0032] Specifically, the support base 21 is in close contact with the thimble base 3. A cavity 5 for accommodating the support base 21 is provided on the fixed base 1, and the cavity 5 is communicated with the hollow groove 4.

[0033] The thimble 22 is fixedly connected to the support base 21, and the thimble 22 penetrates through the hollow groove 4.

[0034] In this embodiment, the support base 21 and the thimble 22 are integrally formed. The support base 21 at the end of the thimble 22 increases the contact surface between the thimble 22 and the thimble base 3. Under the same pressure condition, the pressure of the thimble 22 on the thimble base 3 is reduced, and further the deformation of the thimble base 3 caused by the thimble 22 is reduced, so that there is no need to correct the thimble 22 during the installation process of the thimble 22.

[0035] In order to prevent the ejector pin 22 from shaking during operation, the side wall of the ejector pin 22 is in close and sliding contact with the inner wall of the hollow groove 4. The inner wall of the hollow groove 4 can position the ejector pin 22. On the one hand, it prevents the ejector pin 22 from shaking during operation, and on the other hand, it can reduce the skew of the ejector pin 22, thus effectively ensuring the smooth progress of the chip bonding operation.

[0036] Further, a fixing spring 7 is provided between the support base 21 and the inner wall of the cavity 6. The fixing spring 7 is used to push the support base 21 towards the ejector pin base 3.

[0037] Specifically, the fixing spring 7 is in a compressed state. The elastic force of the fixing spring 7 pushes the support base 21 towards the ejector pin base 3, thereby realizing the fixation of the ejector pin 22 in the hollow groove 4 and the cavity 6, and thus realizing the stable lifting of the chip by the ejector pin 22.

[0038] In a specific embodiment, the fixing spring 7 is sleeved outside the ejector pin 22. The ejector pin 22 can position the fixing spring 7. During the compression process of the fixing spring 7, the fixing spring 7 will not be overly twisted, thus prolonging the service life of the fixing spring 7.

[0040] The present utility model can flexibly adjust the number and distribution of the ejector pins according to actual needs, and has a wide application range. In addition, the ejector pins are positioned by the hollow grooves and supported and fixed by the ejector pin base, realizing the reliable positioning of the ejector pins and solving the problem of ejector pin skew. It has the characteristics of simple structure and convenient operation.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these changes and modifications.
