Description

Technical Field

[0001] The present invention relates to the technical field of clamps, and in particular to a clamp for coupling an optical module and a use method thereof. Background Art

[0002] In the manufacturing industry, using work-holding fixtures to accurately position and clamp key components is a common method for realizing various processes such as production, processing, and assembly. At present, the clamping methods mainly include movable slider clamps, top or bottom pressure clamps, and vacuum adsorption clamps. However, all three clamping methods have limitations. Among them, the movable slider clamp has more structural parts, which limits its potential for miniaturization and requires high precision of the workpiece; secondly, when clamping key components by top or bottom pressure, the base surface of the key component needs to be pushed up or down, which not only affects the convenience of clamping, but also increases the risk of damage to the components due to collision if there are components on the base surface of the key component; finally, the vacuum adsorption method has strict requirements on the adsorption area, flatness, roughness and other conditions, so it cannot be widely used in all types of key components.

[0003] Therefore, the above three clamping methods all have limitations in application and cannot be universally applied to key components of different specifications or types.

[0052] In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] Embodiment 1:

[0054] Embodiment 1 of the present invention provides a clamp for coupling an optical module, such as Figure 1 and Figure 2 As shown, it includes: a coupling clamp 1, an elastic clamp 2 and a driving assembly 3; the upper surface of the coupling clamp 1 is used to carry a clamped part 5; the driving assembly 3 is arranged on the coupling clamp 1, and is used to push or loosen the elastic clamp 2; one end of the elastic clamp 2 is fixed to one side of the coupling clamp 1, and the other end of the elastic clamp 2 is driven by the driving assembly 3 to clamp the clamped part 5 or loosen the clamped part 5.

[0055] remove Figure 2 In addition to the structural form of the elastic clamp 2 and the drive assembly 3 shown in Figure 2a As shown, the lower end of the elastic clamp 2 can also be first plugged and fixed to the coupling clamp 1 and then fixedly connected by bolt connection or adhesive connection, and the driving component 3 is arranged on the opposite side of the elastic clamp 2.

[0056] The clamped component 5 may be a printed circuit board (PCB) or other components that need to be clamped laterally, which is not specifically limited herein.

[0057] In practical application scenarios, especially in the field of optoelectronic integrated circuits, it is necessary to accurately position and clamp the printed circuit board (PCB) used for optical module coupling, which is particularly important for integrated optoelectronic circuits in the processes of patch, bonding, coupling, and assembly. The PCB is provided with circuit traces, electronic components (such as capacitors, resistors, triodes, field effect transistors) and chips (such as microprocessors, laser driver chips, limiting amplifiers, clock data recovery, power management chips, data processing chips), etc. The PCB connects the electrical components in the optical module together according to the circuit design through the circuit traces to achieve electrical functions such as power supply, electrical signal transmission and grounding. The PCB is generally a rigid circuit board. Due to its relatively hard material, the rigid circuit board can also achieve a bearing function, such as the rigid circuit board can stably carry the chip. The method of this embodiment can clamp the PCB in a lateral clamping manner, which can avoid the problem of component damage caused by the top or bottom pressing method, has no requirements for the roughness of the PCB, can be applied to PCBs of different plates and different specifications, and has a simple structure and high precision.

[0058] In addition to the above structures, see Figure 3 As shown, the optical module coupling fixture also includes a working platform 6, a mounting seat 7 and a cross fine-tuning frame 8, the cross fine-tuning frame 8 is arranged on the working platform 6, the mounting seat 7 is arranged on the cross fine-tuning frame 8, the coupling fixture 1 is arranged on the upper surface of the mounting seat 7, and the cross fine-tuning frame 8 is used to fine-tune the position of the coupling fixture 1 on the working platform 6.

[0059] In other embodiments, Figure 3 As shown, a pressing plate 4 may be further provided on the outer side of the elastic clamping plate 2. The pressing plate 4 will be described in detail in Embodiment 2, and only the structure other than the pressing plate 4 is shown more clearly here.

[0060] In one embodiment, if the operation required for the clamped part 5 is optical coupling curing, the optical module coupling clamp further includes a first ultraviolet lamp assembly 90, a second ultraviolet lamp assembly 91 and a clamping arm 92, wherein the first ultraviolet lamp assembly 90 and the second ultraviolet lamp assembly 91 are respectively located on both sides of the mounting seat 7, and are fixed to the working platform 6 by a support member (not shown in the figure), and the first ultraviolet lamp assembly 90 and the second ultraviolet lamp assembly 91 are used to perform optical curing on components from the side of the clamped part 5 plate; a gantry 93 is provided on the working platform 6, and a sliding mechanism 930 is provided on the gantry 93, and the clamping arm 92 is provided on the sliding mechanism 930, and the clamping arm 92 is located above the clamped part 5, and the clamping arm 92 is used to clamp the coupling part and couple it with the clamped part 5, and glue is dispensed after the coupling is completed, and the glue is photocured by the first ultraviolet lamp assembly 90 and the second ultraviolet lamp assembly 91, so as to fix the coupling part and the clamped part 5.

[0061] By arranging a driving component 3 on one side of the coupling clamp 1 and an elastic clamp 2 on the other side, the elastic clamp 2 is driven to move by the driving component 3, so that the elastic clamp 2 can clamp or release the clamped part 5. The present invention adopts a side clamping method. Compared with the existing movable slider type clamping, top or bottom pressure type clamping and vacuum adsorption type clamping methods, there is no need to consider the layout of components on the surface of the clamped part 5, as well as the adsorption area, flatness and roughness of the surface of the clamped part 5. The types of clamped parts 5 used are more extensive, which reduces the possibility of damaging the clamped part 5 during operation. In addition, the structural design is simplified, and the overall volume of the clamp is smaller, which is conducive to improving the production efficiency of the product.

[0062] In order to make the elastic splint 2 realize the elastic function and maintain the accuracy of the fixed position and the stability of the fixed position of the elastic splint 2, in one embodiment, as Figure 4 As shown, the elastic clamp 2 includes a fixing portion 20, an elastic portion 21 and a clamping portion 22, wherein the fixing portion 20 is located at the lower end of the elastic clamp 2, and the clamping portion 22 is located at the upper end of the elastic clamp 2, and the fixing portion 20 is fixedly connected to the elastic clamp 2. Figure 4 and Figure 5 As shown, the coupling clamp 1 is provided with a fixing protrusion 10, and the fixing portion 20 is provided with a fixing groove 200, and the fixing protrusion 10 and the fixing groove 200 are coupled and fixed. The fixing protrusion 10 is used to realize the positioning of the elastic clamp 2, so that the elastic clamp 2 can accurately clamp the clamped member 5 when installed, and the fixing protrusion 10 and the fixing groove 200 can be fixedly connected by bolts.

[0063] Continue reading Figure 4As shown, the connection between the elastic part 21 and the fixing part 20 is a square wave groove grating structure 210, and the square wave groove grating structure 210 is used to realize the elastic function of the elastic clamp 2. Figure 4a As shown, a preset distance d1 is set between the end surface of the clamping portion 22 abutting against the clamped part 5 and the end surface of the fixing portion 20 and the coupling clamp 1, and the preset distance d1 can be 2mm-3mm, so as to achieve the clamping and releasing function of the elastic clamp 2 on the clamped part 5. The connection between the elastic portion 21 and the fixing portion 20 is designed as a square wave groove grid structure 210, which can not only realize the elastic function of the elastic clamp 2, but also help to reduce metal fatigue damage and increase the service life of the elastic clamp 2. The square wave groove grid structure 210 can be designed and adjusted according to the size of the clamping force required by the clamped part 5 to meet the requirements of the same type of clamping. When the elastic clamp 2 needs to be replaced, the elastic clamp 2 can be removed from the fixing protrusion 10 and replaced.

[0064] After the clamped part 5 is placed on the coupling fixture 1, in order to better realize the clamping effect of the coupling fixture 1 and the elastic clamping plate 2 on the clamped part 5, as shown in FIG. Figure 4a , Figure 5 and Figure 6 As shown, the side of the clamping portion 22 is extended with a first abutting protrusion 220, and the upper surface of the coupling clamp 1 is provided with a supporting protrusion 11 and a second abutting protrusion 12. The supporting protrusions 11 are respectively located on both sides of the coupling clamp 1. The supporting protrusions 11 are used to support the clamped part 5. The second abutting protrusion 12 is located on the opposite side of the first abutting protrusion 220. The second abutting protrusion 12 is located on the upper surface of one of the supporting protrusions 11. The first abutting protrusion 220 and the second abutting protrusion 12 are used to clamp and fix the clamped part 5. In order to further ensure the supporting effect of the supporting protrusion 11 on the clamped part 5, the supporting protrusion 11 is provided as follows Figure 5 If the abutting surfaces of the first abutting protrusion 220 and the second abutting protrusion 12 with the clamped member 5 are both vertical surfaces, the clamped member 5 may not abut tightly with the surface of the supporting protrusion 11 during abutment, thereby affecting the accuracy of the clamped member 5 when coupling with the optical device. Figure 7 As shown, the first abutting protrusion 220 is provided with a first inclined surface 2200, and the second abutting protrusion 12 is provided with a second inclined surface 120, and the first inclined surface 2200 and the second inclined surface 120 are used to press the clamped part 5 against the surface of the supporting protrusion 11. The heights of the first inclined surface 2200 and the second inclined surface 120 are slightly higher than the clamped part 5, so as to achieve the effect of pressing the clamped part 5 against the surface of the supporting protrusion 11.

[0065] The first abutting protrusion 220 and the second abutting protrusion 12 are used to position the two sides of the clamped member 5. If only the two sides of the clamped member 5 are restricted, it is not enough to achieve the complete positioning of the clamped member 5. Therefore, Figure 8 As shown, a limit stopper 13 is provided on the side surface of the coupling fixture 1, and the limit stopper 13 is arranged vertically relative to the supporting protrusion 11. First abutting surfaces 50 are respectively provided on both sides of one end of the clamped member 5, and the first abutting surface 50 abuts against the limit stopper 13. The limit stopper 13 is used to cooperate with the second abutting protrusion 12 to limit the position of the clamped member 5 on the coupling fixture 1. Specifically, the limit stopper 13 and the coupling fixture 1 can be fixedly connected by bolts, and the limit stopper 13 protrudes from the coupling fixture 1 by a preset distance, so that the clamped member 5 can abut against the limit stopper 13.

[0066] In the above solution, the driving assembly 3 is arranged on the other side of the coupling fixture 1, and the driving assembly 3 is used to drive the elastic clamp 2 to move, specifically including: Fig. 9 As shown, the driving assembly 3 includes a cylinder 30 and a connecting rod 31. The cylinder 30 is arranged on one side of the coupling clamp 1, and the cylinder 30 is located on the opposite side of the elastic clamp 2. The cylinder 30 is used to control the movement of the connecting rod 31; a butt joint 310 is arranged at one end of the connecting rod 31, and the inner side surface of the butt joint 310 abuts against the elastic clamp 2, so that the butt joint 310 applies pressure to the elastic clamp 2 or releases the elastic clamp 2.

[0067] In order to allow the connecting rod 31 to pass through the coupling clamp 1 and the elastic clamp 2, the coupling clamp 1 is provided with a first through hole 14, and the elastic clamp 2 is provided with a second through hole 23, and the first through hole 14 and the second through hole 23 are used for the connecting rod 31 to pass through.

[0068] When the driving assembly 3 pulls the elastic clamp 2, since the piston of the cylinder 30 moves at a high speed, in order to prevent the clamped part 5 from being damaged by the pressure applied by the elastic clamp 2, a fourth through hole 15 is provided on the coupling clamp 1, one end of which is closed by a flat nut 150, and a buffer spring 151 is provided in the fourth through hole 15, one end of which abuts against the flat nut 150, and the other end abuts against the elastic clamp 2. In addition, in addition to playing a buffering role, the buffer spring 151 also applies a certain thrust to the elastic clamp 2 when the elastic clamp 2 is reset, further assisting the reset of the elastic clamp 2. Specifically, the position abutted by the buffer spring 151 is the clamping portion 22 of the elastic clamp 2, which is arranged close to the first abutting protrusion 220, and can also abut against the elastic portion 21 to achieve a buffering effect.

[0069] According to the technical solution provided by the above content, an embodiment of the present invention also provides a method for using a clamp for coupling an optical module, which is applicable to the clamp for coupling an optical module described in the above solution, such as Fig.10 As shown, including:

[0070] In step S1 , the clamped member 5 is placed at a preset position of the coupling fixture 1 .

[0071] The preset position is a placement area of ​​the clamped part 5 which is limited by the support protrusion 11 , the second abutment protrusion 12 and the limit stopper 13 on the upper surface of the coupling fixture 1 .

[0072] In step S2, the driving assembly 3 is started, and the driving assembly 3 drives the elastic clamp 2 to move toward the clamped part 5. The elastic clamp 2 cooperates with the coupling clamp 1 to apply a clamping force to the clamped part 5 from the side.

[0073] When the clamped member 5 is fixed by the coupling clamp 1 and the elastic clamp plate 2 , the first abutting protrusion 220 and the second abutting protrusion 12 abut against two side edges of the clamped member 5 .

[0074] In step S3, after the operation of the clamped part 5 is completed, the driving component 3 is started, and the driving component 3 releases the pressure applied to the elastic clamp 2, so that the elastic clamp 2 moves away from the clamped part 5, the elastic clamp 2 is reset, and the clamped part 5 is taken out.

[0075] Embodiment 2:

[0076] The embodiment of the present invention adds a pressure plate 4 to the clamp on the basis of the embodiment 1, so that the clamp can be applied to more working environments. Different from the aforementioned embodiment 1, the connection relationship between the driving component 3 and the elastic clamp 2 is adjusted, and the driving component 3 changes from directly driving the elastic clamp 2 to driving the pressure plate 4 to move.

[0077] Combination Figure 4 and Fig.11 The clamp also includes a pressing plate 4, which is in contact with the outer side of the elastic clamp 2. Specifically, the pressing plate 4 is in contact with the elastic portion 21 and the clamping portion 22. In the process of the pressing plate 4 pressing the elastic clamp 2, if the operating plane is not flat enough or the operating environment is unstable, in order to ensure that the position of the pressing plate 4 relative to the position of the elastic clamp 2 remains unchanged, limit baffles 41 are provided on both sides of the pressing plate 4. The inner side walls of the limit baffles 41 are in contact with both sides of the elastic clamp 2 to limit the moving trajectory of the elastic clamp 2. The driving assembly 3 is connected to the pressing plate 4, and is used to drive the pressing plate 4 to move, and then drive the elastic clamp 2 to move through the pressing plate 4 to achieve the clamping function.

[0078] In one embodiment, in combination Fig. 9 , it is necessary to adaptively adjust the connection relationship between the driving assembly 3 and the elastic clamping plate 2. Specifically, the driving assembly 3 includes a cylinder 30 and a connecting rod 31, the cylinder 30 is arranged on one side of the coupling clamp 1, and the cylinder 30 is located on the opposite side of the elastic clamping plate 2, and the cylinder 30 is used to control the movement of the connecting rod 31; the connecting rod 31 of the driving assembly 3 passes through the elastic clamping plate 2, and the abutment 310 on the connecting rod 31 abuts against the pressing plate 4 to apply external force to the pressing plate 4.

[0079] In actual use, when the clamped part 5 is clamped, the driving assembly 3 drives the pressure plate 4 to push the elastic clamp 2 to move; when the clamped part 5 is removed, the driving assembly 3 releases the pressure on the pressure plate 4, so that the pressure plate 4 releases the pressure on the elastic clamp 2, and the buffer spring 151 (see Fig. 9 As shown) pushes the elastic splint 2 to reset, so that Fig.12 As shown, the pressing plate 4 is provided with a third through hole 40 , and the third through hole 40 is used for the connecting rod 31 of the driving assembly 3 to pass through, and the inner side surface of the abutment head 310 abuts against the pressing plate 4 .

[0080] In an optional solution, the pressing plate 4 can be in the form of a flat straight plate, or can be in the form of Fig.12 In the form shown, third abutment protrusions 42 are provided at the upper and lower ends of the pressure plate 4. The third abutment protrusion 42 located below the pressure plate 4 is located above the square wave groove grid structure 210 of the elastic clamp 2, and the third abutment protrusion 42 located above the pressure plate 4 is arranged close to the first abutment protrusion 220, so that when the pressure plate 4 moves toward the direction of the elastic clamp 2, it can press the elastic pressure plate 4, and after the pressure plate 4 is reset, the elastic clamp 2 can also rebound and reset.
