Description

Technical Field

[0001] This utility model relates to the field of optical communication manufacturing, and in particular to a wire bonding workbench. Background Technology

[0002] TO (Transistor Outline) is a transistor package designed to allow leads to be shaped and used for surface mounting. With the increasing application of transistors, TO wire bonding technology has also accelerated its development. A TO product consists of a TO socket and a TO cap. The TO socket acts as the base of the packaged component, providing it with power, while the cap enables smooth optical signal transmission.

[0003] In addition, the TO series products are diverse and have different applications, with varying cap diameters and lead lengths. During the wire bonding process, based on the characteristics of the TO products, the TO products are fixed in high-temperature resistant fixtures to prevent displacement of the TO products during the wire bonding process.

[0004] Currently, for TO products with very small diameters, disassembly is inconvenient, it is impossible to use clamps for press-type fixing, and batch fixing is not possible. Utility Model Content

[0012] Furthermore, each of the first limiting holes has a dome protrusion at its bottom; the dome protrusion fits into the second inner groove.

[0013] Furthermore, the diameter of the first inner groove is smaller than the diameter of the tube seat.

[0014] Preferably, a second adsorption area is provided on the outer edge of the second limiting area. The second adsorption area includes a plurality of mounting holes, and a magnet is installed in the mounting holes. The magnet attracts the cover plate.

Detailed Implementation

[0028] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Similar component reference numerals in the drawings represent similar components. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] It should be understood that, when used in this specification and the appended claims, the terms "comprising" and "including" indicate the presence of the described features, integrals, steps, operations, elements and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components and / or collections thereof.

[0030] It should also be understood that the terminology used in this specification of embodiments of the present invention is for the purpose of describing particular embodiments only and is not intended to limit the embodiments of the present invention. As used in this specification of embodiments of the present invention and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0031] Please refer to the following: Figure 1 The present invention provides a wire bonding workbench for fixing TO products 14 for wire bonding, including a mounting part 1 for fixing and mounting TO products 14 and a heating part 2 for heating TO products 14.

[0032] Please refer to the following: Figure 2 In this embodiment, the heating part 2 is provided with a groove 221 for inserting the mounting part 1. The length and width of the groove 221 are slightly larger than the length and width of the base plate 13. The bottom of part of the mounting part 1 is inserted into the groove 221. The heating part 2 includes a first heating block 21, and a second heating block 22 is provided above the first heating block 21. The first heating block 21 is provided with a first adsorption area 211. Preferably, in this embodiment, the first adsorption area 211 is located on the bottom surface of the groove 221. The first adsorption area 211 includes a plurality of adsorption holes 212, and the adsorption holes 212 are connected to the external air. After the mounting part 1 is embedded in the groove 221, the bottom of the mounting part 1 and the groove 221 form a relatively closed chamber (relatively closed means that although the chamber may leak due to the gap between the side wall of the mounting part 1 and the side wall of the groove 221, the mounting part 1 can still be adsorbed at the bottom of the groove 221 when the vacuum is turned on). When the vacuum is turned on, the heating part 2 will tightly adsorb the mounting part 1. There is no need to use drilling to fix it. The disassembly step can be completed by directly putting the mounting part 1 into the groove 221 and turning on the vacuum or turning off the vacuum.

[0033] Please refer to the following: Figure 3 In this embodiment, the mounting part 1 includes a support plate 12, a cover plate 11, and a base plate 13. The TO product 14 is first placed in the support plate 12 and then fixed by the cover plate 11. The support plate 12 and the cover plate 11 are fixed by magnetic adsorption. Specifically, in this embodiment, a second adsorption area 123 is provided on the outer edge of the second limiting area 121. Multiple mounting holes 1231 can be opened in the second adsorption area 123 according to the weight or size of the cover plate 11. Figure 6The diagram shows that a mounting hole 1231 is drilled upwards on the side of the support plate 12 facing away from the second limiting area 121. A magnet 1232 is installed in the mounting hole 1231. The magnet 1232 magnetically attracts the cover plate 11, thus assembling and positioning the cover plate 11 on the support plate 12. During the production process, because the support plate 12 is heated, to ensure the reliable use of the magnet 1232, it is preferable to fix the magnet 1232 and the mounting hole 1231 using a slight interference fit or by bonding with high-temperature resistant adhesive. The cover plate 11 is made of metal, such as steel, while the base plate 13 and the support plate 12 are made of a material with good thermal conductivity, such as aluminum alloy.

[0034] Please refer to the following: Figure 4 , Figure 5 In this embodiment, the cover plate 11 is provided with a first limiting area 111, the first limiting area 111 includes a plurality of first limiting holes 1111, and the bottom of each first limiting hole 1111 is provided with a dome protrusion 1112; the carrier plate 12 includes a second limiting area 121, the second limiting groove includes a slot hole 1213, a first inner groove 1211 is provided around the slot hole 1213, and a second inner groove 1212 is provided on the outer edge of the first inner groove 1211; the TO product 14 passes through the first limiting hole 1111 and the dome protrusion 1112 and is installed in the second inner groove 1212, and the lower surface of the cover plate 11 is adjusted to be in complete contact with the upper surface of the carrier plate 12. TO product 14 includes multiple pins 141 and tube sockets 142. The pins 141 are placed in the first inner groove 1211, the second inner groove 1212, the first limiting hole 1111, and the dome protrusion 1112, which correspond one-to-one and are coaxially arranged. When the cover plate 11 is assembled onto the carrier plate 12, each TO product 14 is pressed down and positioned on the carrier plate 12 by the cover plate 11, so as to achieve complete positioning.

[0035] Please refer to the following: Figure 6 In this embodiment, a first positioning area 112 is further provided on the outer edge of the first limiting area 111, and the first positioning area 112 includes a positioning hole 1121; a second positioning area 122 is further provided on the outer edge of the second limiting area 121, and the second positioning area 122 includes a positioning pin 1221. When the cover plate 11 and the carrier plate 12 are assembled, the positioning pin 1221 passes through the positioning hole 1121 to position the cover plate 11 and the carrier plate 12, thereby further ensuring that the first inner groove 1211, the second inner groove 1212, the first limiting hole 1111, and the dome protrusion 1112 correspond one-to-one and are coaxially arranged, preventing displacement of the two, improving positioning accuracy, and thus helping to improve the production quality of TO products. In the actual production process, it is preferable that the TO products 14 are arranged in a matrix pattern and fixed in the carrier plate 12 by the cover plate 11. It should be noted that a safe distance is spaced between each row in the carrier plate 12 to prevent interference between the welding head and the TO products 14 during the wire bonding process.
