Description

Technical Field

[0001] The present invention relates to the technical field of conveying structures, and in particular to a high-speed automatic feeding device for optical module detection. Background Art

[0002] Optical modules are key components in fiber-optic communication systems. They are responsible for the conversion between electrical signals and optical signals and are widely used in data centers, enterprise networks, metropolitan area networks, and telecommunication networks. With the rapid development of fiber-optic communication technology, strict testing of optical modules is the key to ensuring stable and reliable operation of optical modules in various complex working environments.

[0003] At present, the mainstream scheme for detecting optical modules mainly relies on loading equipment, transfer robots and detection equipment. The loading equipment transports the carrier loaded with multiple optical modules to the bottom of the transfer robot. The transfer robot sends the optical modules one by one to the detection equipment for detection, and returns the carrier after detection. In order to improve the detection efficiency, technical personnel in this field have proposed many improvements to the above scheme, such as: 1. Improve the structure of the robot to increase the transfer speed of the optical module from the carrier to the detection equipment; 2. Increase the carrier conveying speed of the loading equipment to increase the speed of the carrier from the loading equipment to the transfer robot. But in fact, simply increasing the moving speed of a certain structure is prone to jitter, vibration and other phenomena when the speed is too fast, which leads to inaccurate positioning of the optical module.

[0045] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0046] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation of the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally arranged component at the same time.

[0047] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0048] The high-speed automatic loading device for optical module detection provided in this embodiment is suitable for the scenario of loading the optical module 540. Specifically, the production process of the optical module 540 involves multiple processes such as processing, assembly, detection, and cleaning of the optical module 540. Different processes correspond to processing equipment, assembly equipment, detection equipment and other equipment. For this, a loading device (transfer device) is required to realize the flow function of the optical module 540 between different equipment; however, with the improvement of the detection efficiency of the detection equipment, the existing loading device has been difficult to keep up with the detection efficiency. Therefore, in this embodiment, the structure of the high-speed automatic loading device for optical module detection is improved, so that the conveying efficiency is improved and the conveying accuracy is guaranteed.

[0049] like Figure 1As shown, the high-speed automatic loading device for optical module detection in this embodiment includes a tray loading component 100, a conveying component 200 and a tray unloading component 300 arranged in sequence along a first direction, and the conveying component 200 is provided with a first material changing station 201 and a second material changing station 202 arranged in sequence along the first direction; a transport component 400 is provided on one side of the conveying component 200; wherein, a plurality of tray units 500 are stored in the tray loading component 100, and each tray unit 500 is loaded with an optical module 540, and the tray loading component 100 can realize the function of placing the tray units 500 one by one on the conveying component 200 through a lifting cylinder and a horizontal shift cylinder, and it is obvious that the tray The loading component 100 can also realize the transfer of the carrier unit 500 from the carrier loading component 100 to the conveying component 400 through other forms such as a push rod cylinder. Its specific structure is well known to those skilled in the art and will not be specifically expanded in this embodiment; the carrier unloading component 300 has a cabin for recovering the carrier unit 500, and is also equipped with structures such as a lifting cylinder and a horizontal shift cylinder, which can lift the carrier unit 500 from the conveying component 200 to the cabin one by one. Obviously, the carrier unloading component 300 can also realize the function of unloading from the conveying component 200 through other structures such as a robotic arm and a robotic hand. Its specific structure is well known to those skilled in the art and will not be specifically expanded in this embodiment.

[0050] like Figures 1 to 4 As shown, the conveying assembly 200 is used to deliver the tray unit 500 in the tray loading assembly 100 to the first material change station 201, and to deliver the tray unit 500 that has completed the preset number of inspections from the first material change station 201 to the second material change station 202; the handling assembly 400 is used to deliver the optical module 540 on the tray unit 500 to the inspection assembly. Figures 4 to 9 As shown, a plurality of mounting positions 501 are provided on the carrier unit 500, a clamping gap 502 is left between two adjacent mounting positions 501, a transition component 600 is movably provided in the clamping gap 502, and the optical module 540 on the mounting position 501 is abutted by the transition component 600; when the clamping end of the conveying component 400 extends into the clamping gap 502, the transition component 600 is abutted by the clamping end in a direction close to the inside of the clamping gap 502 to partially absorb the kinetic energy of the clamping end.

[0051] Specifically, in the optical module detection high-speed automatic loading device of the present embodiment, when detecting the optical module 540, the tray unit 500 in the tray loading assembly 100 is first sent to the first material changing station 201 through the conveying assembly 200, and the handling assembly 400 sequentially sends the optical module 540 on the tray unit 500 to the detection assembly and puts it back to the tray unit 500 after the detection. After completing the preset number of detections (exemplary: the loading capacity of the tray unit 500-N, N is 1 or 2), the tray unit 500 is moved to the second material changing station 202, and the first material changing station 201 is re-sent into another tray unit 500, so after completing the first material changing station 201, the optical module 540 on the tray unit 500 is sent to the detection assembly and put back into the tray unit 500. After all the optical modules 540 of the carrier unit 500 on the second material changing station 202 are detected, the transport component 400 can directly transport the optical modules 540 on another carrier unit 500, thereby saving the time for the transport component 400 to wait for the carrier unit 500 to be replaced; at the same time, when the clamping end of the transport component 400 extends into the clamping gap 502, it pushes the transition component 600 on one side to move toward the inside of the clamping gap 502, which means that the transition component 600 partially absorbs the kinetic energy of the clamping end at this time, so that even if the speed of the clamping end is increased, there will be no excessive impact, etc., thereby ensuring positioning accuracy and improving transportation efficiency. It can be seen that the improved high-speed automatic loading device for optical module detection improves transportation efficiency while ensuring accuracy.

[0052] Furthermore, the conveying assembly 200 includes a conveyor belt assembly 210, and the conveyor belt assembly 210 includes two conveyor belt units 211 arranged at intervals, and the conveyor belt unit 211 can be driven to transport the carrier unit 500 along a first direction; a positioning assembly 700 is respectively provided at the first material changing station 201 and the second material changing station 202, and the positioning assembly 700 includes a lifting part 710, and a lifting block 720 is installed at the lifting end of the lifting part 710, and the lifting block 720 is used to support the carrier unit 500, so as to lift the bottom support carrier unit 500 from the conveyor belt unit 211, or, the bottom support carrier unit 500 is lowered to the conveyor belt unit 211.

[0053] It is understandable that the conveyor belt assembly 210 further includes a conveyor motor 212 and a conveyor bracket 213, the conveyor motor 212 is mounted on the conveyor bracket 213, and the conveyor belt unit 211 is mounted on the conveyor bracket 213 via a synchronous wheel; therefore, after the tray loading assembly 100 is placed on the conveyor belt unit 211, the conveyor belt unit 211 can be driven to rotate by the conveyor motor 212, thereby transporting the tray unit 500 along the first direction. Until the tray unit 500 moves to above the first material changing station 201, the lifting part 710 lifts the lifting block 720, and lifts the tray unit 500 from the conveyor belt unit 211, thereby reducing the start and stop time of the conveyor motor 212, so as to improve the transportation efficiency.

[0054] Furthermore, in order to improve the positioning accuracy, along the first direction, a blocking portion 730 is also provided on one side of the lifting portion 710, and the blocking portion 730 includes a lifting end that can be lifted and lowered relative to the conveyor unit 211, and the lifting end is equipped with an blocking block 740; along the first direction, a first horizontal positioning portion 750 is also provided on the other side of the lifting portion 710, and the first horizontal positioning portion 750 includes a horizontal cylinder installed on the lifting block 720, and the horizontal cylinder includes a horizontal movable end that can move along the first direction, and the horizontal movable end is equipped with a first positioning block 760, and a space for clamping the carrier unit 500 is formed between the first positioning block 760 and the blocking block 740.

[0055] It should be supplemented that the positioning assembly 700 also includes a second horizontal positioning portion 770 and a second positioning block 780 respectively arranged on both sides of the conveyor belt assembly 210 along the second direction; the second horizontal positioning portion 770 includes a horizontal movable end that can move in a direction close to or away from the second positioning block 780.

[0056] It can be understood that when the tray unit 500 moves to above the first material changing station 201 and is detected by sensors such as laser sensors and infrared sensors, the blocking block 740 is first lifted by the blocking portion 730 to prevent the movement of the tray unit 500; then the tray unit 500 is lifted from the conveyor belt assembly 210 by the lifting portion 710; then, the first positioning block 760 is pushed by the first horizontal positioning portion 750, and its horizontal movable end is pushed by the second horizontal positioning portion 770, so as to clamp and position the tray unit 500 from the first direction and the second direction respectively, thereby ensuring the positioning accuracy of the tray unit 500.

[0057] In this embodiment, the lifting part 710, the blocking part 730, the first horizontal positioning part 750 and the second horizontal positioning part 770 are all cylinders. As other optional implementations, structures with telescopic functions such as oil cylinders and telescopic rod motors can be selected, which is not limited in this embodiment.

[0058] Furthermore, if Figure 6 and Figure 7As shown, there are at least a plurality of mounting positions 501 arranged at intervals along a second direction on the carrier unit 500, the second direction is perpendicular to the first direction and is arranged parallel to the ground; the carrier unit 500 is provided with mounting grooves 510 corresponding to the positions of the mounting positions 501, and the carrier unit 500 is provided with clamping grooves 520 along the second direction, the clamping grooves 520 penetrate through the plurality of mounting grooves 510, and the clamping gaps 502 are located in the areas where the clamping grooves 520 and the mounting grooves 510 do not overlap. It can be understood that, in this embodiment, a plurality of strip-shaped mounting grooves 510 are provided on the carrier unit 500, and the extension direction of the strips is parallel to the first direction, and the clamping grooves 520 are also strip-shaped, and the extension direction of the strips is parallel to the second direction, so there are overlapping areas and non-overlapping areas between the clamping grooves 520 and the mounting grooves 510, and the non-overlapping areas are the clamping gaps 502. As shown Figure 5 As shown, the transition component 600 is installed on the lifting block 720, and the bottom wall of the clamping groove 520 is provided with an avoidance groove 530 corresponding to each transition component 600. It can be understood that the clamping gap 502 is actually located on the clamping groove 520. Therefore, the avoidance groove 530 is provided on the bottom wall of the clamping groove 520 to ensure that the transition component 600 is limited from both sides of the optical module 540. At the same time, since the transition component 600 is installed on the lifting block 720, it can be adapted to each carrier unit 500 at the same time, which can effectively reduce the material cost.

[0059] Based on the above implementation, Figures 5 to 9 As shown, the transition assembly 600 includes a transition plate 610, and the transition plate 610 is installed with a plurality of transition parts 620 at intervals along the second direction, and the transition parts 620 are arranged one by one corresponding to the avoidance grooves 530; the transition part 620 includes two transition blocks 621 arranged opposite to each other along the second direction, and the transition block 621 is slidably connected with the transition plate 610 along the second direction, and a spring (not shown) is arranged between the two transition blocks 621, and the spring is respectively abutted against the two transition blocks 621; and a guiding inclined surface 6211 is formed on the end of the transition block 621 facing the adjacent installation groove 510. Among them, the transition block 621 can be provided with a guide column or a guide groove corresponding to the end of the spring to limit the spring.

[0060] Exemplarily, when the lifting block 720 is lifted, the transition portion 620 passes through the avoidance groove 530 and extends into the clamping gap 502. At this time, a transition portion 620 is provided between each pair of optical modules 540. Then, when the clamping end extends into the clamping gap 502, the clamping end squeezes into between the optical module 540 and the adjacent transition block 621, and is inserted into between the optical module 540 and the adjacent transition block 621 through the guiding slope 6211. At this time, the spring is compressed and transmitted through force, so that each spring in the same clamping groove 520 is compressed, so that Figure 6For example, when the clamping end is inserted between the top optical module 540 and the adjacent transition block 621, the spring in the top transition portion 620 is compressed, which means that the second optical module 540 will be squeezed by the upper transition block 621, so that the spring in the second transition portion 620 will also be compressed, thereby strengthening the clamping force on other optical modules 540 and preventing the optical modules 540 from accidentally falling out. At the same time, the compression of the spring also absorbs kinetic energy, thereby reducing impact.

[0061] Furthermore, if Figure 8 and Fig. 9 As shown, the transition portion 620 also includes a damping member 622 disposed between two transition blocks 621, and a damping block 623 is installed at the end of the damping member 622; the damping block 623 includes a first damping slope 6231 facing the transition block 621, and the transition block 621 is formed with a second damping slope 6212 at a position corresponding to the first damping slope 6231; the first damping slope 6231 and the second damping slope 6212. It can be understood that when the transition blocks 621 move toward each other, the damping block 623 moves downward by the arrangement of the first damping slope 6231 and the second damping slope 6212 to trigger the damping member 622 to absorb kinetic energy, and the structure has the advantage of being compact. As a preferred embodiment, the damping member 622 can be a cavity storing damping oil, and the damping block 623 can partially extend into the cavity to compress the damping oil when the damping block 623 moves downward, thereby converting kinetic energy.

[0062] Furthermore, if Figure 6 and Figure 7 As shown, the avoidance groove 530 includes a central groove 531, and the two ends of the central groove 531 along the first direction are respectively connected to the edge grooves 532; along the second direction, the width of the edge groove 532 is smaller than the central groove 531; wherein, when the transition block 621 contacts the groove wall of the edge groove 532, the spacing between the two transition blocks 621 is smaller than the spacing of the clamping gap 502; when the transition block 621 contacts the groove wall of the central groove 531, the transition block 621 abuts against the adjacent optical module 540.

[0063] It is understandable that when the carrier unit 500 is lifted from the conveyor assembly 210 by the lifting portion 710, the transition portion 620 passes through the avoidance groove 530. At this time, since the carrier unit 500 is not aligned, the groove wall of the edge groove 532 plays a role in squeezing the two transition blocks 621, so that the transition blocks 621 do not contact the optical module 540. When the first positioning block 760 is pushed by the first horizontal positioning portion 750 and its horizontal movable end is pushed by the second horizontal positioning portion 770, it means that the carrier unit 500 is clamped and positioned from the first direction and the second direction. At this time, the edge groove 532 does not contact the two transition blocks 621, and the transition blocks 621 are completely located in the central groove 531. At this time, under the action of the spring, the two transition blocks 621 are respectively in contact with the adjacent optical modules 540. Through the above-mentioned arrangement, it is avoided that the transition blocks 621 interfere with the optical module 540 during the rising process, and at the same time, the positioning effect of the transition portion 620 on the optical module 540 is improved.

[0064] Based on the above implementation, Figure 6 As shown, a plurality of columns of mounting positions 501 are arranged on the carrier unit 500 , and the same number of transition assemblies 600 as the number of columns of the mounting positions 501 are installed on the lifting block 720 .

[0065] like Fig.10 As shown, the transport assembly 400 includes a horizontal moving platform 410, a rotating platform 420, a clamping claw lifting unit 430 and a clamping claw cylinder 440; the rotating platform 420 is arranged on the moving end of the horizontal moving platform 410, the clamping claw lifting unit 430 is arranged on the rotating end of the rotating platform 420, and the clamping claw cylinder 440 is installed on the lifting end of the clamping claw lifting unit 430. The clamping claw cylinder 440 includes at least two clamping claws (clamping ends), and the two clamping claws can clamp the optical module 540 from both sides.

[0066] To facilitate the understanding of those skilled in the art, the operation process of the high-speed automatic loading device for optical module detection is explained as follows:

[0067] 1. The tray loading assembly 100 delivers a tray unit 500 to the conveying assembly 200, and the conveying assembly 200 delivers the tray unit 500 to the first material changing station 201. At this time, the blocking block 740 and the lifting block 720 are lifted successively, and the tray unit 500 is first stopped by the blocking block 740, and then lifted from the conveyor belt assembly 210 by the lifting block 720; at the same time, the transition portion 620 passes through the avoidance groove 530 and extends into the clamping gap 502. At this time, the groove wall of the edge groove 532 squeezes the two transition blocks 621, and the transition blocks 621 do not contact the optical module 540;

[0068] 2. The first horizontal positioning portion 750 pushes the first positioning block 760, and when the second horizontal positioning portion 770 pushes its horizontal movable end, the carrier unit 500 is clamped and positioned from the first direction and the second direction; at the same time, the transition block 621 enters the central groove 531, and under the action of the spring, the two transition blocks 621 are respectively in contact with the adjacent optical modules 540;

[0069] 3. The transport assembly 400 takes out the optical modules 540 one by one, sends them to the detection equipment for detection, and puts them back into the carrier unit 500 after detection; when the clamping end extends into the clamping gap 502, it is inserted between the optical module 540 and the adjacent transition block 621 through the guiding slope 6211, so that the spring is compressed and the damping block 623 descends to absorb kinetic energy, and at the same time, the transition block 621 releases the corresponding optical module 540, so that other optical modules 540 can be further clamped by other transition parts 620;

[0070] 4. The horizontal movable ends of the lifting block 720, the blocking block 740, the first positioning block 760, and the second horizontal positioning portion 770 are reset to send the remaining two optical modules 540 that have not been detected to the second material changing station 202; at this time, the carrier unit 500 is lifted and positioned in a similar manner to the second step, the handling assembly 400 is put back to the third optical module 540 from the bottom, and the remaining two optical modules 540 that have not been detected are sent to the detection device in turn;

[0071] 5. The horizontal movable ends of the lifting block 720 , the blocking block 740 , the first positioning block 760 , and the second horizontal positioning portion 770 are reset, and the tray unit 500 is sent into the tray unloading assembly 300 .

[0072] In summary, the high-speed automatic feeding device for optical module detection provided in this embodiment has the advantages of high positioning accuracy, high conveying efficiency, high stability, compact structure, and low cost.
