Description

Technical Field

[0001] This utility model belongs to the field of optical device processing equipment, specifically an optical device bonding and baking device. Background Technology

[0002] In optical device manufacturing, surface mount technology (SMT) and photopolymerization are core processes in the packaging process, directly impacting device performance, reliability, and yield. SMT involves precisely mounting optical devices such as laser chips (LDs), photodetectors (PDs), and silicon photonic chips onto substrates such as heat sinks, PCBs, and housings. The core objective is to achieve mechanical fixation, electrical connection, and optical alignment. Photopolymerization involves heating and curing adhesives such as black glue, UV glue, and silver glue to ensure stable bonding and release stress. It is commonly used in the later stages of optical device packaging.

[0003] The holder is a key component in the surface mount and adhesive bonding processes, primarily used to fix and position optical devices, ensuring precise alignment and stability during production. Lenses are mainly used for optical path control, focusing, divergence, and aberration correction, while glass slides refer to planar transparent optical substrates or glass slides with phase modulation capabilities, used for protection, filtering, or polarization control. The holder, as the load-bearing structure, secures the lenses and glass slides using methods such as slots, clamps, or bonding.

[0004] Current adhesive bonding processes require multiple steps. First, the support is placed in a fixture, the lens is installed into the support, adhesive is applied, and then the adhesive is baked. Next, the support is removed from the fixture, reversed, installed back into the fixture, the slide is inserted, adhesive is applied, and the adhesive is baked again. After baking, the assembly of the support, lens, and slide is removed from the fixture and placed in the designated location.

[0005] This process requires the bracket to be unloaded from the tooling twice before being transferred to the designated location, which makes the adhesive baking process cumbersome. Furthermore, the longer the turnover time, the higher the probability of the bracket colliding with the lens and glass slide. Utility Model Content

[0006] The purpose of this invention is to provide a bonding and baking device for optical devices, so as to solve the problems of cumbersome bonding and baking processes and long turnaround times that increase the probability of collision between the support, lens and glass slide.

[0007] To solve the above-mentioned technical problems, this utility model provides a bonding and baking device for optical devices, including an optical device fixing bracket and an assembly fixture body. The optical device fixing bracket is used to fix and position the lens part and the glass slide part. The assembly fixture body is provided with a plurality of bracket receiving cavities. The assembly fixture body is block-shaped, and the bracket receiving cavities are used to accommodate the optical device fixing bracket. The assembly fixture body is detachably connected to the assembly turnover base.

[0008] Furthermore, the assembly fixture body includes a top surface and a bottom surface, and the bracket receiving cavity penetrates through the assembly fixture body. The optical device fixing bracket enters and exits the bracket receiving cavity from the top surface of the body.

[0009] Furthermore, a bracket limiting part is provided in the bracket receiving cavity, which is used to limit the optical device fixing bracket entering the bracket receiving cavity.

[0010] Furthermore, the assembly turnover base is provided with a main body receiving cavity, which is used to accommodate the main body of the assembly tooling.

[0011] Furthermore, the main body of the assembly tooling is provided with several main body removal cavities, which are used to remove the main body of the assembly tooling from the main body receiving cavity.

[0012] Furthermore, the assembly turnover base includes an inner side wall and an inner bottom, which are vertically connected. The inner side wall is connected to the side of the main body of the assembly tooling, and the inner bottom is connected to the top or bottom surface of the main body.

[0013] Furthermore, a first limiting groove and two second limiting grooves are provided around the inner sidewall of the base, with the second limiting grooves positioned on top of the first limiting groove. This is located between the bottom of the base.

[0014] Furthermore, a first limiting rod and a second limiting rod are slidably connected to the inner side wall of the base; one end of the first limiting rod is slidably connected to a first limiting groove, and the other end is slidably connected to another first limiting groove; one end of the second limiting rod is slidably connected to a second limiting groove, and the other end is slidably connected to another second limiting groove; the first limiting rod and the second limiting rod are used to limit the optical device fixing bracket on the bottom of the base.

[0015] Furthermore, a limit rod notch is provided on the inner wall of the base, which is used by the user to move the first limit rod or the second limit rod.

[0016] Furthermore, the optical device fixing bracket has an internal cavity, and a lens limiting part is provided in the internal cavity. The lens part enters the internal cavity from one side of the optical device fixing bracket and abuts against the lens limiting part, while the glass slide part enters the internal cavity from the other side of the optical device fixing bracket.

[0017] The beneficial effects of the mounting and baking device for optical devices provided by this utility model are as follows: The optical device fixing bracket is used to fix and position the lens part and the glass slide part. The main body of the assembly fixture is provided with several bracket receiving cavities. The bracket receiving cavities are used to accommodate the optical device fixing bracket. The main body of the assembly fixture is detachably connected to the assembly turnover base. After the optical device fixing bracket is installed into the main body of the assembly fixture, glue is applied, the lens part is installed, and then the glue is baked. After the glue dries, the assembly turnover base is placed on the main body of the assembly fixture, and the assembly turnover base is rotated 180°. Then the glass slide part is installed, glue is applied, and then it is baked. After the glue dries, the main body of the assembly fixture is removed, and the optical device fixing bracket remains on the assembly turnover base. In this process, it is not necessary to remove the optical device fixing brackets from the main body of the assembly fixture one by one and then reinstall them, nor is it necessary to remove them one by one and place them in a designated position after baking. This reduces the number of removal steps and the complexity of the adhesive baking process. At the same time, the turnover process reduces the turnover time and the probability of collisions between the optical device fixing bracket and the lens and glass plate because it eliminates the need to remove, reinstall, and remove each optical device fixing bracket.

[0024] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 6 The present invention provides a more detailed description of a bonding and baking device for optical devices.

[0025] like Figures 1 to 6As shown, an embodiment of the present invention provides a bonding and adhesive application device for optical devices, comprising an optical device holder 100 and an assembly fixture body 400. The optical device holder 100 is used to fix and position the lens portion 200 and the glass slide portion 300. The assembly fixture body 400 is provided with a plurality of bracket receiving cavities 410. The assembly fixture body 400 is block-shaped, and the bracket receiving cavities 410 are used to accommodate the optical device holder 100. The assembly fixture body 400 is detachably connected to an assembly turnover base 500. The assembly fixture body 400 includes a top surface 420 and a bottom surface 430. The bracket receiving cavities 410 penetrate the assembly fixture body 400, and the optical device holder 100 enters and exits the bracket receiving cavity 410 from the top surface 420. The optical device fixing bracket 100 has an inner cavity 110 inside, and a lens limiting part 111 is provided in the inner cavity 110. The lens part 200 enters the inner cavity 110 from one side of the optical device fixing bracket 100 and abuts against the lens limiting part 111. The glass slide part 300 enters the inner cavity 110 from the other side of the optical device fixing bracket 100.

[0026] In use, several optical device fixing brackets 100 are placed into several bracket receiving cavities 410 of the assembly fixture body 400 through the top surface 420 of the main body. Each bracket receiving cavity 410 can hold one optical device fixing bracket 100.

[0027] After the optical device mounting bracket 100 is placed into the bracket receiving cavity 410, adhesive is applied to the lens limiting part 111 in the bracket inner cavity 110 using an adhesive dispensing device. This adhesive dispensing process is for the subsequent fixing of the lens part 200. After the adhesive dispensing on the lens limiting part 111 is completed, the main body is inserted into the bracket inner cavity 110 through the top surface 420 and comes into contact with the adhesive on the lens limiting part 111.

[0028] After the lens part 200 is placed, the first gluing process is required. The assembly fixture body 400, together with the optical device fixing bracket 100 on it, is placed into the gluing equipment for the first gluing process.

[0029] After the first coat of adhesive is applied, the assembly turnover base 500 is placed on top of the assembly fixture body 400, with the assembly turnover base 500 contacting the top surface 420 of the body but not the bottom surface 430. At this point, the assembly turnover base 500 is above the assembly fixture body 400. Then, the assembly fixture body 400 and assembly turnover base 500 assembly assembly combination is rotated 180°, resulting in an assembly configuration where the bottom surface 430 of the assembly fixture body 400 faces upwards, and the assembly turnover base 500 is below the assembly fixture body 400.

[0030] Next, the slide portion 300 is placed into the inner cavity 110 of the bracket through the bottom surface 430 of the main body, followed by adhesive application. A second adhesive baking process is then performed. After the second adhesive baking, the assembly fixture main body 400 is removed separately. At this point, all the optical component fixing brackets 100 of the assembly fixture main body 400 remain on the assembly turnover base 500. Subsequently, it is only necessary to send the assembly turnover base 500, along with the optical component fixing brackets 100 on it, to the next process. In this process, it is not necessary to remove each optical component fixing bracket 100 individually; instead, they are flipped together with the assembly fixture main body 400 and sent to the next process together with the assembly turnover base 500. This simplifies the process flow.

[0031] In this utility model, in order to prevent the optical device fixing bracket 100 from falling out of the assembly fixture body 400 after being placed into the bracket receiving cavity 410, a bracket limiting part 411 is provided in the bracket receiving cavity 410. When the optical device fixing bracket 100 is placed into the bracket receiving cavity 410 through the top surface 420 of the main body, the optical device fixing bracket 100 will not fall out of the assembly fixture body 400 from the bottom surface 430 of the main body due to the limiting part 411.

[0032] In some embodiments, the assembly turnover base 500 is provided with a main body receiving cavity 510 for accommodating the assembly fixture main body 400. The assembly turnover base 500 is a box-shaped structure with an open top, and the assembly fixture main body 400 is mounted inside the assembly turnover base 500. The side walls of the assembly turnover base 500 also provide a certain degree of restraint on the assembly fixture main body 400, preventing movement of the assembly fixture main body 400 relative to the assembly turnover base 500 during operation, thereby preventing such movement from causing damage to the optical device fixing bracket 100 and its internal lens portion 200 and / or slide portion 300.

[0033] To facilitate the removal of the assembly fixture body 400 from the assembly turnover base 500, several body removal cavities 440 are provided on the assembly fixture body 400. These cavities are used to remove the assembly fixture body 400 from the body receiving cavity 510. When it is necessary to remove the assembly fixture body 400, the operator can insert their fingers or gripping tools into the body removal cavities 440, thus easily removing the assembly fixture body 400 from the assembly turnover base 500.

[0034] Understandably, the assembly turnover base 500 includes an inner sidewall 520 and an inner bottom 530. The inner sidewall 520 and the inner bottom 530 are vertically related. The inner sidewall 520 is connected to the side of the assembly tooling body 400, and the inner bottom 530 is connected to the top surface 420 or the bottom surface 430 of the body.

[0035] After flipping the assembly fixture body 400 and the assembly turnover base 500, the side of the assembly fixture body 400 mates with the inner sidewall 520 of the base. The assembly fixture body 400 is then placed on the inner bottom 530 of the base. Of course, before flipping, the assembly fixture body 400 can also be placed in the assembly turnover base 500, in which case the bottom surface 430 of the body is in contact with the inner bottom 530 of the base.

[0036] In some embodiments, the inner sidewall 520 of the base is provided with a first limiting groove 521 and two second limiting grooves 522 around its perimeter. The second limiting grooves 522 are located between the first limiting groove 521 and the bottom of the base 530. A first limiting rod 523 and a second limiting rod 524 are slidably connected to the inner sidewall 520 of the base. One end of the first limiting rod 523 is slidably connected to one first limiting groove 521, and the other end is slidably connected to the other first limiting groove 521. One end of the second limiting rod 524 is slidably connected to one second limiting groove 522, and the other end is slidably connected to the other second limiting groove 522. The first limiting rod 523 and the second limiting rod 524 are used to limit the optical device fixing bracket 100 on the bottom of the base 530. A limiting rod notch is provided on the inner sidewall 520 of the base, which is used by the user to move the first limiting rod 523 or the second limiting rod 524.

[0037] The first limiting rod 523 slides in the two first limiting grooves 521 perpendicular to it, or it can be stored in the first limiting groove 521 parallel to it. The same applies to the second limiting rod 524. When the assembly fixture body 400 is installed in the assembly turnover base 500, the first limiting rod 523 is stored in the first limiting groove 521, and the second limiting rod 524 is stored in the second limiting groove 522. After the assembly fixture body 400 is removed from the assembly turnover base 500, leaving the assembly turnover base 500, the assembly turnover base 500 can be restricted to a square area by moving the first limiting rod 523 and the second limiting rod 524. This reduces the damage to the optical device fixing bracket 100 caused by mutual movement or even collision between the optical device fixing bracket 100 and the assembly turnover base 500 during turnover.

[0038] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
