Description

Technical Field

[0001] This invention belongs to the field of communications, and specifically relates to a miniature PD chip mounting and wire bonding anti-rotation device that is small in size, simple in structure, convenient to use, low in cost, and simple and efficient in production and assembly. Background Technology

[0002] The mini PD25 chip is increasingly used in communication products. Due to its high-performance photodiode packaging, and its special optical design, the product has the advantages of high responsivity, low dark current, and high reliability. Because of its compact structure and small size (maximum socket diameter 2.36mm), it is easy to integrate into high-density fiber optic communication systems. However, because of its compact structure and small size, the current industry base design does not have a limiting structure. This will cause the socket to rotate and shift after the PD chip is mounted, making it impossible to automatically generate the subsequent wire bonding process. This is because automated wire bonding relies on image recognition of the position of the socket and the chip, and the position must remain unchanged (cannot be rotated).

[0003] If a device could be developed that structurally clamps the tube seat, all the above problems would be solved, thus effectively meeting the usage requirements. The technical problem to be solved by the present invention is to provide a miniature PD chip mounting and wire bonding anti-rotation device that can realize tube socket non-rotation and displacement, automated generation of all processes, small size and simple and compact structure, convenient use and low cost, simple production and assembly and high efficiency, and effectively meet the needs of use. Summary of the Invention

[0004] To address the problems of existing technologies, such as the lack of a limiting structure for the base, the susceptibility of the tube seat to rotational displacement, and the inability to automatically generate subsequent wire bonding processes, this invention adopts the following technical solution: This invention provides an anti-rotation device for miniature PD chip mounting and wire bonding, comprising a main module, a knob, a push rod, a slider, an elastic pressure block, and a bottom cover. The main module has several countersunk grooves on one side of its upper top plate, with product insertion through holes formed concentrically at each countersunk groove. The knob is located inside the main module on one side. The push rod is located at the front end of the knob and the two are fixedly connected by screws. A stud is located at the center of the push rod. An internal thread is formed at the center of the slider. The slider is located at the front end of the push rod, and the push rod is threadedly fastened to the internal thread of the slider via the stud. The elastic pressure block is located above the front end of the slider and the two are fixedly connected by screws. The bottom cover is fastened and fixed to the bottom of the main module, with its top tightly against the bottom surface of the slider.

[0005] Furthermore, the number of countersunk grooves is more than ten.

[0006] The beneficial effects of this invention are as follows: by rotating the knob, the push rod, slider and pressure block move and press the product, which has strong positioning ability, good use effect, small overall size and simple and compact structure, convenient use and low cost, simple production and assembly and high efficiency, effectively meeting the use needs.

[0010] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0011] Please see Figure 1 An anti-rotation device for miniature PD chip mounting and wire bonding includes a main module 1, a knob 2, a push rod 3, a slider 4, an elastic pressure block 5, and a bottom cover 6. The upper top plate 11 of the main module 1 has several countersunk grooves 12 on one side, wherein the number of countersunk grooves is more than ten. Figure 2 The diagram shows 10, but this is not the only option; the specific number can be configured according to actual needs. Product insertion through holes 13 are provided concentrically at each of the countersunk grooves 12. The product enters from the countersunk groove and passes through the product insertion through holes until it reaches the main module. The part of the product to be operated is exposed inside the countersunk groove. The knob 2 is located on one side inside the main module 1. The push rod 3 is located at the front end of the knob 2, and the two are fixedly connected by screws. A stud is provided at the center of the push rod 3. An internal thread is provided at the center of the slider 4. The slider 4 is located at the front end of the push rod 3, and the push rod 3 is connected to the push rod 3. The stud and slider 4 are fastened together by internal threads. The elastic pressure block 5 is located above the front end of slider 4 and the two are fixedly connected by screws. The bottom cover 6 is fastened to the bottom of the main body mold 1 and its top is close to the bottom surface of slider 4. During operation, multiple products are first inserted into the device. At this time, the products cannot be moved, but they can rotate. To prevent rotation, the knob needs to be turned first to drive the push rod to rotate. As the push rod rotates, it drives the slider forward. The forward movement of the slider drives the elastic pressure block to push forward and press down on the product's tube feet, forming a four-sided compression shape. Figure 3 As shown, the product is now in a completely fixed state, unable to move or rotate.

[0012] The beneficial effects of this invention are as follows: by rotating the knob, the push rod, slider and pressure block move and press the product, which has strong positioning ability, good use effect, small overall size and simple and compact structure, convenient use and low cost, simple production and assembly and high efficiency, effectively meeting the use needs.

[0013] The above embodiments are not intended to limit the product form and style of the present invention. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of the present invention.
