[0033] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0035] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features limited to "first" and "second" may explicitly or implicitly include at least one of the features. In addition, if "and / or" or "and / or" appears in the full text, its meaning includes three parallel solutions. Taking "A and / or B" as an example, it includes solution A, solution B, or solutions that satisfy both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the utility model.
[0036] The production process of optical modules includes welding, screwing and gluing, all of which involve clamping and positioning of the optical modules to be processed. To ensure accurate positioning, rigid clamping and positioning are often used. However, rigid clamping and positioning are prone to produce large reaction forces, which may cause over-pressure deformation of the outer shell structure of the optical module or over-pressure displacement of the clamping components. Of course, there are also flexible clamping and positioning methods, but flexible clamping and positioning will affect the accuracy of centering the optical module.
[0037] Analysis of the above reasons shows that both the simple rigid clamping positioning and the simple flexible clamping positioning have different problems. It is possible to consider combining the rigid clamping positioning with the flexible clamping positioning to position the optical module through a rigid and flexible positioning method, which will neither cause overpressure deformation of the optical module nor affect the position accuracy of the optical module.
[0038] In view of this, the utility model proposes a clamping assembly, a lifting clamping device and an optical module processing equipment, aiming to solve the problem that the shell structure of the optical module is easily subjected to overpressure and deformed during the existing clamping and positioning process. Figure 1 A structural schematic diagram of an embodiment of an optical module processing device provided by the utility model; Figure 2 for Figure 1 The formal structural diagram of the optical module processing equipment; Figure 3 for Figure 2 A schematic diagram of the structure of the middle clamping assembly; Figure 4 for Figure 2 Structural schematic diagram of the middle lifting structure and the mounting seat.
[0039] Please refer to the figure Figure 2 and 3 In one embodiment of the utility model, the clamping assembly 2 includes a rigid moving part 21 and a flexible moving part 22 which are relatively arranged in a first direction to form a clamping gap 2a therebetween. The clamping gap 2a is used to place the optical module. The rigid moving part 21 and the flexible moving part 22 can be relatively close to each other in the first direction to clamp the optical module. The rigid moving part 21 has a reference positioning position within its movable stroke.
[0040] It should be noted that the rigid moving part 21 refers to a part whose movement stroke is not limited by the position of the optical module. Within the set movement stroke, the rigid moving part 21 can always reach the reference positioning position, and the optical module can only move with its movement, while the flexible moving part 22 refers to a part whose movement stroke is limited by the position of the optical module. For example, after being pushed by the rigid moving part 21, the optical module blocks the movement of the flexible moving part 22. After being blocked, the flexible moving part 22 cannot continue to move to the set position, so as to maintain a position close to the optical module to apply a certain force to the optical module. It should be reminded that the driving The structure for the dynamic rigid moving part 21 to perform rigid movement can have various forms, as long as it has a sufficiently large driving force to drive the light module to move and prevent the light module from retreating, and this embodiment does not limit it. The structure for driving the flexible moving part 22 to perform flexible movement can also have various forms, as long as it has a relatively small driving force to limit the movement of the light module toward the flexible moving part 22, and this embodiment does not limit it. The rigid moving part 21 and the flexible moving part 22 can be set on the mounting component at the same time or on different mounting components respectively, as long as their relative positions are in the first direction.
[0041] The technical solution of the utility model can push the optical module in the clamping interval 2a to the reference point position through the rigid moving part 21, and the flexible moving part 22 can cooperate with the rigid moving part 21 to apply a reverse force along the first direction to the optical module, so as to limit the optical module to the reference positioning position to ensure the processing position accuracy of the optical module. At the same time, the movement of the flexible moving part 22 can be blocked by the optical module, so that the applied force is relatively small, so it is difficult to cause over-pressure damage to the outer shell structure of the optical module, and at the same time, the rigid moving part 21 and the flexible moving part 22 will not be offset due to over-pressure.
[0042] Specifically, in one embodiment, the clamping assembly 2 further includes a driving cylinder 23, the driving cylinder 23 has a piston rod that is telescopically movable along a first direction, and the flexible moving part 22 is installed on the piston rod. It should be noted that the driving cylinder 23 is a flexible driving member, and since it is driven by air pressure, and the driving force of the air pressure drive is relatively small, to a certain extent, the piston rod can be blocked by the outside world and stay at a certain position during the extension process. According to the above technical solution, by driving the flexible movable part to perform flexible movement through the driving cylinder 23, overpressure damage to the outer shell structure of the optical module can be avoided.
[0043] In other embodiments, the clamping assembly 2 can also achieve a flexible driving effect by applying an elastic structure to the driving end of the rigid driving component and arranging the flexible moving part 22 on the elastic structure.
[0044] Specifically, in another embodiment, the clamping assembly 2 further includes a push rod motor 24, the push rod motor 24 has a push rod that can be telescopically movable along a first direction, and the rigid motion part 21 is installed on the push rod. It should be noted that the push rod motor 24 is a rigid driving component, and through appropriate selection, it can ensure that the thrust output by it is sufficient to push the optical module to move, and the threaded transmission therein can form a self-locking to limit the push rod movement of the optical module to push the push rod motor 24 in the reverse direction. According to the above technical solution, the push rod motor 24 can rigidly push the optical module in the clamping interval 2a to the reference positioning position, so that the processing execution component 300 can process it.
[0045] In other embodiments, the clamping assembly 2 may also be driven by a hydraulic cylinder. Compared with cylinder drive, hydraulic drive is also a rigid drive.
[0046] In one embodiment, the rigid moving part 21 includes a rigid clamping block; and / or the flexible moving part 22 includes an elastic clamping block.
[0047] It should be noted that the above two parallel technical solutions "rigid moving part 21 includes a rigid clamping block" and "flexible moving part 22 includes an elastic clamping block" can be set either one or at the same time. Obviously, setting them at the same time will have a better effect.
[0048] According to the above scheme, by setting the rigid moving part 21 as a rigid clamping block, it can be further ensured that the rigid moving part 21 can push the optical module to reach the reference positioning position, and by setting the flexible moving part 22 as an elastic clamping block, the flexibility of the flexible moving part 22 can be enhanced, and the probability of the flexible moving part 22 crushing the optical module can be further reduced.
[0049] Since the optical module is generally hexahedral, its size in one direction is generally longer. In view of this, in one embodiment, a plurality of rigid moving parts 21 are arranged at intervals in the third direction, and / or a plurality of flexible moving parts 22 are arranged at intervals in the third direction; wherein the third direction is perpendicular to the first direction.
[0050] It should be noted that the above two parallel technical solutions "multiple rigid moving parts 21 are arranged at intervals in the third direction" and "multiple flexible moving parts 22 are arranged at intervals in the third direction" can be set one by one or at the same time. Obviously, the effect of setting them at the same time is better; in the process of clamping the optical module, the third direction can be understood as the direction consistent with the length direction of the optical module, and the first direction can be understood as the direction consistent with the width direction of the optical module.
[0051] According to the above solution, by providing a plurality of rigid moving parts 21 and flexible moving parts 22 , a force can be applied to the optical module at various positions along the length direction, thereby forming a more stable clamping effect on the optical module.
[0052] See also Figure 2 and Figure 4 The utility model also proposes a lifting clamping device 100, which includes a working platform 1, a clamping assembly 2 as any one of the above items, and a lifting support structure 3, wherein the working platform 1 is formed with a lifting station; the rigid moving part 21 and the flexible moving part 22 of the clamping assembly 2 are distributed on both sides of the lifting station along a first direction; the lifting support structure 3 is arranged on the working platform 1 corresponding to the lifting station, and the lifting support structure 3 is movably arranged on the working platform 1 in a second direction to lift the optical module at the lifting station to the clamping interval 2a of the clamping assembly 2, wherein the lifting support structure 3 has multiple movement strokes.
[0053] It should be noted that the lifting and supporting structure 3 is located at the bottom of the clamping assembly 2, so that the optical module can be lifted to the clamping interval 2a of the clamping assembly 2; the specific structure of the clamping assembly 2 refers to the above embodiment. Since the lifting and clamping device 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here one by one.
[0054] The technical solution of the utility model can lift the optical module transported to the lifting station to a preset reference height through the movement of the lifting and holding structure 3, and at the same time, it is in the clamping interval 2a of the clamping assembly 2, and then the optical module can be positioned and clamped in three-dimensional space through the activities of the rigid moving part 21 and the flexible movement, thereby ensuring the positioning accuracy of the optical module. Moreover, since the lifting and holding structure 3 has multiple movement strokes, this means that the lifting and holding structure 3 can select different lifting heights according to optical modules of different specifications, thereby ensuring that the to-be-processed surfaces of optical modules of different specifications can always be lifted to the set height, so as to facilitate processing by the processing execution assembly 300, thereby expanding the scope of application of the lifting and clamping device 100.
[0055] Generally speaking, the optical module is transported to the lifting station by the conveying mechanism through the tooling plate. Therefore, the tooling plate and the conveying mechanism will block the movement of the lifting structure 3. In view of this, please refer to Figure 4 In one embodiment, the lifting and supporting structure 3 has two extensions 31 opposite to each other in a first direction to form a clearance gap 3a therebetween. The two extensions 31 extend in a second direction, and a supporting portion 32 is formed at the end of the extension 31. The supporting portion 32 extends in the first direction to support the optical module at the lifting position.
[0056] It should be noted that, in the process of clamping the optical module, the second direction can be understood as a direction consistent with the height direction of the optical module. According to the above technical solution, through the relative arrangement of the two extension parts 31, the supporting part 32 that directly contacts the optical module can be extended upward, and the clearance gap 3a formed therebetween can play a role in avoiding the conveying mechanism. Therefore, the conveying mechanism can be selected as a conveyor belt or a roller conveyor line.
[0057] There are many ways to realize the multi-stroke of the lifting and holding structure 3. For example, the servo motor can drive the screw rod to drive the wire sleeve to move, and the conveying interval of the servo motor can be controlled to achieve different strokes. However, due to the heavy weight of the optical module, this driving method requires the selection of a larger servo motor and a screw rod wire sleeve structure, which may lead to an increase in cost. At the same time, its stroke control accuracy is poor. In view of this, please refer to Figure 4 In one embodiment, the working platform 1 has a mounting seat 11 arranged at the bottom corresponding to the jacking station; the jacking support structure 3 is arranged on the mounting seat 11, and a double-stroke jacking cylinder 4 is also arranged between the mounting seat 11, and the double-stroke jacking cylinder 4 has two cylinder rods 41 located on both sides of the second direction, and the two cylinder rods 41 are respectively arranged on the jacking support structure 3 and the mounting seat 11, and can be telescopically moved along the second direction respectively.
[0058] It should be noted that the two cylinder rods 41 of the double-stroke lifting cylinder 4 can form three different movement strokes, that is, individually controlling the two cylinder rods 41 to extend can form two different and shorter movement strokes, and simultaneously controlling the two cylinder rods 41 to extend can form a maximum movement stroke.
[0059] According to the above technical solution, a double-stroke lifting cylinder 4 is set as the driving source of the lifting and supporting structure 3. The two cylinder rods 41 of the double-stroke lifting cylinder 4 can form three different movement strokes, so that the lifting and supporting structure 3 can lift the optical module to three different heights. In order to adapt to the double-stroke lifting cylinder 4, the mounting seat 11 is set to set the overall position of the lifting and supporting structure 3 at the bottom of the lifting station.
[0060] It is not difficult to understand that the cylinder seat of the double-stroke lifting cylinder 4 lacks installation due to the need for follow-up, resulting in the lack of limit in the first direction and the third direction of the lifting structure 3. Figure 4 In one embodiment, a linear guide structure 5 is further provided between the lifting and supporting structure 3 and the mounting seat 11, and the linear guide structure 5 is extended along the second direction to provide guidance for the lifting and supporting structure 3 in the second direction. The linear guide structure 5 includes a linear guide rail slider structure or a guide rod sliding sleeve structure, and the specific structure is not limited in this embodiment. The linear guide structure 5 can provide guidance for the lifting and supporting structure 3 in the second direction to prevent the lifting and supporting structure 3 from abnormal displacement.
[0061] See also Figure 1 and Figure 2The utility model also proposes an optical module processing device 1000, which includes a lifting and clamping device 100, a three-axis motion module 200 and a processing execution component 300 as described above. The three-axis motion module 200 is arranged on the working platform 1 of the lifting and clamping device 100, and the three-axis motion module 200 has a movable seat at the end. The processing execution component 300 is arranged on the movable seat, and the processing execution component 300 includes at least one of a gluing component, a soldering component and a screw driving component. The specific structure of the lifting and clamping device 100 refers to the above embodiment. Since the optical module processing device 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here. Among them, the type of the optical module processing equipment 1000 is determined according to the specific processing type of the processing execution component 300. For example, when the processing execution component 300 includes a gluing component, the optical module processing equipment 1000 is an optical module gluing equipment; when the processing execution component 300 includes a soldering component, the optical module processing equipment 1000 is an optical module welding equipment; when the processing execution component 300 includes a screw driving component, the optical module processing equipment 1000 is an optical module screw driving equipment. Of course, the processing execution component 300 can even be two or all of the above three to achieve multiple uses of one machine.
