Description

Technical Field

[0001] The present invention relates to an optical module, and in particular to a multi-channel parallel optical module flatness detection device. Background Art

[0002] A metal cage is provided inside the optical module, which contacts the optical module to achieve heat dissipation. The higher the surface flatness of the optical module and the metal cage, the larger the contact area between the two, which is more conducive to the metal cage to dissipate heat. The existing optical module flatness detection device is not stable enough when moving, which easily increases the error during detection. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a multi-channel parallel optical module flatness detection device to overcome the deficiencies in the above-mentioned prior art.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A multi-channel parallel optical module flatness detection device includes a workbench, a driving component, an elastic pushing component and an electric push rod. A stepped hole is opened in the middle of the workbench, and a slide is provided for sliding inside the stepped hole. Two blocks are provided on the top of the slide. The driving component is arranged at the bottom of the workbench and is transmission-connected to the bottom of the slide. The driving component drives the slide to slide inside the stepped hole. Auxiliary plates parallel to the workbench are provided on both sides of the top of the slide. There are two elastic pushing components and they are arranged on the top of the workbench. The two elastic pushing components elastically squeeze the auxiliary plates in the direction of fitting the workbench. The electric push rod is located at the top of one of the elastic pushing components. The output end of the electric push rod is provided with a flatness detector through a tube bundle.

[0005] The beneficial effects of the present invention are as follows: the optical module is placed on the top of the slide, and the optical module is located between two blocks. The driving component pushes the slide inside the stepped hole to slide on the stepped hole, and the block drives the optical module to move. When the optical module moves, the flatness detector detects the flatness of the optical module, and auxiliary plates are provided on both sides of the slide that elastically contact the elastic pushing component to ensure that the slide slides smoothly inside the stepped hole, improve the stability of the slide when sliding, and thus improve the accuracy of the optical module during plane detection.

DETAILED DESCRIPTION

[0009] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0010] like Figure 1-2 As shown, embodiment 1 of the present invention provides a multi-channel parallel optical module flatness detection device, including a workbench 1, a driving component 2, an elastic pushing component 7 and an electric push rod 8. A stepped hole 3 is opened in the middle of the workbench 1, and a slide plate 4 is provided for sliding inside the stepped hole 3. Two blocks 5 are provided on the top of the slide plate 4. The driving component 2 is arranged at the bottom of the workbench 1 and is transmission-connected to the bottom of the slide plate 4. The driving component 2 drives the slide plate 4 to slide inside the stepped hole 3. Auxiliary plates 6 parallel to the workbench 1 are provided on both sides of the top of the slide plate 4. There are two elastic pushing components 7 and they are arranged on the top of the workbench 1. The two elastic pushing components 7 elastically squeeze the auxiliary plates 6 toward the direction of fitting the workbench 1. The electric push rod 8 is located at the top of one elastic pushing component 7. The output end of the electric push rod 8 is provided with a flatness detector 10 through a tube bundle 9. The model of the electric push rod 8 may be ANT-26.

[0011] The optical module is placed on the top of the slide 4, and the optical module is located between the two blocks 5. The driving component 2 pushes the slide 4 inside the stepped hole 3 to slide on the stepped hole 3, and the block 5 drives the optical module to move. When the optical module moves, the flatness detector 10 detects the flatness of the optical module, and auxiliary plates 6 are provided on both sides of the slide 4, which elastically contact the elastic pushing component 7 to ensure that the slide 4 slides smoothly inside the stepped hole 3, improve the stability of the slide 4 when sliding, and thus improve the accuracy of the optical module during plane detection.

[0012] Embodiment 2 of the present invention provides a multi-channel parallel optical module flatness detection device. Based on embodiment 1, the elastic pushing component 7 includes a support rod 71, which is arranged on the top of the workbench 1. The support rod 71 is L-shaped, and the vertical end of the support rod 71 is arranged on the top of the workbench 1. A spring 72 is provided at the bottom of the horizontal end of the support rod 71, and an arc plate 73 is provided at the bottom of the spring 72. A positioning rod 74 in contact with the auxiliary plate 6 is provided at the bottom of the arc plate 73. The arc plate 73 elastically resists the auxiliary plate 6 through the spring 72, so that the slide plate 4 fits against the inner wall of the stepped hole 3 when moving, thereby improving the stability of the stepped hole 3 when moving.

[0013] Embodiment 3 of the present invention provides a multi-channel parallel optical module flatness detection device. Based on Embodiment 2, a through hole 75 is provided on the horizontal end of the support rod 71, and a positioning rod 74 is provided on the arc plate 73, which passes through the spring 72 and extends to the inside of the through hole 75. The arc plate 73 is guided by the positioning rod 74 to move in the vertical direction, so that the arc plate 73 is vertically attached to the auxiliary plate 6 to avoid the elastic force on the spring 72 from being offset.

[0014] Embodiment 4 of the present invention provides a multi-channel parallel optical module flatness detection device. Based on embodiment 3, the driving component 2 includes a motor 22 and a vertical plate 24. The motor 22 is arranged at the bottom of the workbench 1 through the mounting plate 21. The output end of the motor 22 is provided with a gear 23. The vertical plate 24 is arranged at the bottom of the skateboard 4. The bottom of the vertical plate 24 is provided with a tooth plate 25 engaged with the gear 23. The gear 23 is driven to rotate by the motor 22, and the gear 23 is engaged with the tooth plate 25. The skateboard 4 is driven to move on the stepped hole 3 by the vertical plate 24. The engagement of the gear 23 with the tooth plate 25 makes the skateboard 4 more stable when moving. The model of the motor 22 can be 40M-R3210A5-E.

[0015] Example 5 of the present invention provides a multi-channel parallel optical module flatness detection device. Based on Example 4, the drive component 2 also includes an L-shaped plate 26 arranged on the top of the tooth plate 25, and the bottom of the vertical plate 24 is provided with a horizontal plate 27 that is engaged with the L-shaped plate 26. The horizontal end of the L-shaped plate 26 is engaged with the top of the horizontal plate 27. The tooth plate 25 is movably connected to the vertical plate 24 in the vertical direction through the L-shaped plate 26 and the horizontal plate 27. When the gear 23 engages with the tooth plate 25 to push the slide 4 to move, the engagement of the tooth plate 25 with the gear 23 is avoided to cause the slide 4 to move upward, further improving the smooth movement of the slide 4 on the stepped hole 3.

[0016] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
