Abstract
Description
Technical Field
[0001] This utility model relates to the field of optical device technology, and specifically provides a crimping device for testing optical devices. Background Technology
[0002] After optical devices are manufactured, they undergo multiple tests. During testing, the optical devices need to be electrically connected to the circuitry used for detection. To improve efficiency, a common testing method involves placing the pins on the optical device against the pins on the circuit board. When the two pins are against each other, the optical device and the detection circuit board are electrically connected. At this point, the detection circuit board can input signals into the optical device and then receive signals output by the optical device to obtain the detection data.
[0003] However, when connecting the pins of the optical device to the pins of the testing circuit board, to ensure continuous signal transmission, the two pins need to be kept in a continuous connection state, meaning the optical device and the testing circuit board must always be connected. Current technology primarily uses hand clamps to hold the optical device and the circuit board together, maintaining a stable connection during testing. However, this manual clamping method is prone to loosening due to operator fatigue or posture adjustments, causing testing failures and requiring retesting, thus affecting testing efficiency. Utility Model Content
[0004] This invention provides a crimping device for testing optical devices, which solves the problem of manually fixing optical devices and testing plates during testing.
[0005] The technical solution of this utility model is as follows:
[0006] A crimping device for testing optical devices includes a first movable component, a second movable component, a fixed part, a fixed platform, and a pressure rod. The fixed part is connected to the first movable component, and the pressure rod is connected to the second movable component. The first movable component is fixedly installed, the fixed platform is fixedly installed, and the second movable component is connected to the fixed platform. The fixed part is used to fix the optical device, the fixed platform is used to fix the circuit board for testing, and the pressure rod is located on the upper side of the fixed platform.
[0007] In this solution, a fixing part is used to place optical devices, and a fixing platform is used to place the circuit board for testing. A first moving component moves the fixing part, locating the optical device on it to the corresponding position on the circuit board, ensuring the pins of the optical device align with the pins on the circuit board. A second moving component moves a pressure rod, pressing the optical device from above to maintain a stable connection between the pins of the optical device and the pins on the circuit board. Because the fixing platform is fixed, the position of the circuit board for testing is fixed. The pressure rod, pressed against the optical device by the second moving component, eliminates the need for manual clamping, preventing movement of the optical device during testing due to fatigue or other reasons caused by manual operation, ensuring uninterrupted testing, and improving testing efficiency.
[0008] Preferably, the fixing part is provided with a fixing groove, one side of the fixing groove is a positioning surface, and the other side of the fixing groove is provided with a pressing part. The fixing groove is used to place the optical device, and the pressing part is used to press the optical device from the side.
[0009] In this solution, the side of the fixing groove is used as a positioning surface to position the optical device. A clamping part is set on the other side of the fixing groove to press the optical device onto the positioning surface, thereby improving the positional accuracy of the optical device, enabling more accurate alignment between the pins of the optical device and the pins on the circuit board used for testing, reducing the difficulty of aligning the two pins, improving the alignment efficiency of the two pins, and thus improving the testing efficiency.
[0010] In a preferred embodiment, the side of the fixing groove is provided with a screw hole, the clamping part is a clamping screw, and the clamping screw is connected to the screw hole in a driving connection.
[0011] In this scheme, the advantage of using a clamping screw is that it has a simple and stable structure, is reliable, and is easy to implement.
[0012] To address the problem of excessive pressure exerted on the housing of the optical device by the clamping part, which leads to deformation and damage to the housing, a clamping groove is provided on the side wall of the fixing groove. The clamping part includes a clamping block and a driving part. The driving part is disposed in the clamping groove, and the clamping block is slidably connected to the clamping groove. The driving part is used to push the clamping block to clamp the optical device from the side.
[0013] In this solution, a clamping groove and a clamping block are provided. The clamping groove is used to constrain the sliding direction of the clamping block, while the clamping block can ensure the contact area with the optical device housing, so as to avoid excessive pressure on the optical device housing due to small contact area, and prevent the optical device housing from being deformed or damaged.
[0014] Preferably, the driving part is an elastomer.
[0015] In this solution, the elasticity of an elastomer can be used to drive the clamping block to press the optical device. The elastomer can ensure that the pressure on each optical device is stable, avoiding the optical device from becoming loose or the housing from being crushed due to unstable pressure.
[0016] As an optional implementation, the driving part is a driving screw, the clamping groove is provided with a positioning plate, the positioning plate is provided with an internal threaded hole, and the driving screw is connected to the internal threaded hole in a transmission manner.
[0017] In this solution, a drive screw is used to push the clamping block. The advantage of the drive screw is that it is easy to control and will not always apply pressure to the clamping block, allowing the clamping block to retract into the clamping groove. This avoids the clamping block applying force to the optical device during the picking and placing of the optical device, which would affect the picking and placing of the optical device.
[0018] To address the issue that the clamping screw pressing the clamping block against the housing of the optical device would exert a rigid clamping force on the housing, which could lead to deformation and damage, a buffer spring is provided at the end of the drive screw. One end of the buffer spring abuts against the drive screw, and the other end abuts against the clamping block.
[0019] In this design, the buffer spring can act as a buffer to prevent the clamping block from being subjected to rigid force, thereby preventing the clamping block from exerting rigid force on the housing of the optical device and preventing the housing of the optical device from being deformed and damaged due to rigid force.
[0020] To address the issue that the pins of optical devices cannot align with the pins on the circuit board when the circuit board for testing moves on the fixed platform, the fixed platform is provided with fixing screw holes for fixing the circuit board for testing.
[0021] In this solution, the mounting screw holes secure the circuit board used for testing, ensuring that the pins on the circuit board are aligned with the pins on the optical device. They also position the circuit board to prevent it from moving during testing.
[0022] The circuit board used for testing will have electronic components such as capacitors. To prevent these electronic components from affecting the flatness of the circuit board, a support rod is provided on the top of the fixed platform, and the fixing screw hole is provided in the support rod.
[0023] In this design, the fixing screw holes are located on the support rod, so the support rod supports the circuit board from below, allowing the circuit board to be suspended in the air. This avoids interference between the electronic components on the circuit board and the top surface of the fixing platform, which would prevent the circuit board from being placed flat.
[0024] The pressure bar needs to press the optical device, which actually needs to press the part of the circuit board that extends from the housing of the optical device. The pins of the optical device are set on this part of the circuit board. The circuit board is usually uneven. In order to avoid the pressure bar acting on a single point on the circuit board of the optical device, resulting in excessive pressure concentration, the bottom end of the pressure bar is provided with a swing head, which is hinged to the pressure bar.
[0025] In this design, the swing head is hinged to the pressure rod, allowing the swing head to swing relative to the pressure rod. After the swing head contacts the circuit board of the optical device, it will press the circuit board down under the force of the pressure rod. Then, it will swing under the reaction force of the circuit board, so that the swing head can have enough contact points with the circuit board, avoiding the pressure exerted by the swing head on the circuit board of the optical device being concentrated at one point.
[0026] The beneficial effects of this utility model are:
[0027] This invention uses a fixed platform and a fixed part to fix the circuit board for testing and the optical device to be tested respectively. Then, a pressure rod is used to press the optical device to keep it connected to the circuit board for testing. The mechanical structure prevents the circuit board for testing from detaching from the optical device during testing, which improves the stability of testing, reduces the number of repeated tests, and thus improves the testing efficiency.

[0036] The technical solution of this utility model will be clearly and completely described in conjunction with the accompanying drawings and through specific embodiments.
[0037] Example 1:
[0038] like Figure 1 As shown, this embodiment provides a crimping device for testing an optical device 9, including a first moving component 1, a second moving component, a fixing part 2, a fixing platform 4, and a pressure rod 3. The first moving component 1 is fixedly installed, for example, on a workbench, and the fixing platform 4 is also fixedly installed, for example, on the same workbench as the first moving component 1. After installation, the relative installation positions of the first moving component 1 and the fixing platform 4 remain unchanged. The fixing part 2 is connected to the first moving component 1, and the first moving component 1 is used to move the position of the fixing part 2. The fixing part 2 is used to fix the optical device 9, and the first moving component 1 is used to move the optical device 9 on the fixing part 2 to the circuit board for testing, and to align and contact the pins on the optical device 9 with the pins on the circuit board for testing. The fixing platform 4 is used to fix the circuit board for testing. The first moving component 1 is located on one side of the fixing platform 4, and is used to move the pins of the optical device 9 to the upper side of the corresponding pins on the circuit board for testing, and to contact the two pins. The pressure rod 3 is connected to the second moving component, which is used to move the pressure rod 3 so that the pressure rod 3 presses the optical device 9 from top to bottom, so that the pins of the optical device 9 are connected to the pins of the detection circuit board, thereby preventing the optical device 9 from being displaced during the detection process.
[0039] The first moving component 1 can adopt a three-dimensional micro-adjustment sliding platform. The three-dimensional micro-adjustment sliding platform is a high-precision adjustment platform that is currently available on the market. The fixed part 2 is connected to the three-dimensional micro-adjustment sliding platform. The three-dimensional micro-adjustment sliding platform is used to enable the fixed part 2 to move in the up-down, front-back, and left-rear directions, and to make the movement accuracy as high as 0.01mm.
[0040] Since the optical device 9 itself includes a circuit board and a housing, and the circuit board is a flexible circuit board, fixedly connected to the housing, and the pins on the circuit board are very small with a pin pitch of 0.5mm and a typical pin count of 15, manual alignment is extremely difficult. If the optical device 9 is misaligned with the test pins, even minor misalignments can affect test results, and in severe cases, can cause short circuits and burn out the optical device 9 or the test circuit board. Therefore, a three-dimensional micro-adjustment sliding platform with an accuracy of 0.01mm is used to move the fixing part 2, thereby achieving precise adjustment of the position of the optical device 9.
[0041] The fixing part 2 is a cuboid block structure with a fixing groove 21. The opening of the fixing groove 21 faces upward, and both ends of the fixing groove 21 extend through both sides of the fixing part 2. When the optical device 9 is placed in the fixing groove 21, the housing of the optical device 9 is located in the fixing groove 21, and the circuit board with pins extending from the optical device 9 protrudes from one end of the fixing part 2, so that the pins can contact the pins on the detection circuit board from top to bottom.
[0042] One side of the fixing groove 21 serves as a positioning surface for positioning the housing of the optical device 9, while the other side of the fixing groove 21 is provided with a clamping part for pressing the housing of the optical device 9. The clamping part presses the housing of the optical device 9 against the positioning surface from the side, thereby achieving the function of positioning the optical device 9. Once the housing of the optical device 9 is positioned, the pin positions on the optical device 9 are also fixed.
[0043] The clamping part can be a spring sheet disposed on the side of the fixing groove 21. The spring sheet is an elastic body that can clamp the housing of the optical device 9 with its own elastic force after deformation. When the optical device 9 is installed into the fixing groove 21, the spring sheet is in a compressed state, ensuring that the spring sheet can clamp the optical device 9.
[0044] The second moving component includes a column 5, a crossbeam 6, and a drive mechanism 7. The column 5 has a slotted hole located at its bottom end, with its length parallel to the horizontal direction and perpendicular to the length of the column 5. The fixed platform 4 has a threaded hole with a screw inserted through it, securing the column 5 to the platform 4. To adjust the position of the column 5, the slotted hole can be moved relative to the screw, thus moving the column 5 relative to the platform 4. A column 5 is located at each end of the fixed platform 4, and the crossbeam 6 is connected to both ends of the column 5, with the crossbeam 6 positioned on top of the platform 4. Slotted holes are located on both sides of the crossbeam 6, with their lengths aligned vertically. The crossbeam 6 is fixed to the column 5 with screws, and the height of the crossbeam 6 can be adjusted by the interaction of the slotted holes and screws. A slotted hole is provided in the middle of the crossbeam 6, and the slotted hole is arranged along the length of the crossbeam 6. The drive mechanism 7 is connected to the crossbeam 6 by screws, which pass through the slotted hole in the middle of the crossbeam 6 and are connected to the drive mechanism 7, so that the drive mechanism 7 can move along the length of the crossbeam 6. The drive mechanism 7 is connected to the pressure rod 3, and the drive mechanism 7 is used to drive the pressure rod 3 to move up and down.
[0045] The drive mechanism 7 can be a motor, a cylinder, a pressure rod 3 with a self-locking function, or other mechanisms.
[0046] The pressure bar 3 is used to press the optical device 9 and the circuit board used for testing, preventing the optical device 9 from moving relative to the testing circuit board during the testing process, and ensuring that the pins on the optical device 9 are aligned with the pins on the testing circuit board.
[0047] like Figure 5 As shown, a swing head 10 is provided at the end of the pressure rod 3. The swing head 10 is hinged to the pressure rod 3, allowing the swing head 10 to swing relative to the pressure rod 3. The pressure rod 3 includes a rod body 32 and a rotating sleeve 31. The rotating sleeve 31 is rotatably connected to the rod body 32 and is connected to the swing head 10. That is, a mounting groove is formed in the rotating sleeve 31. Because the rotating sleeve 31 can rotate relative to the rod body 32, the swing of the swing head 10 and the rotation of the rotating sleeve 31 cooperate, allowing the swing head 10 to swing in any direction when it is subjected to a reaction force from the circuit board of the optical device 9.
[0048] The fixed platform 4 is provided with fixing screw holes for fixing the circuit board for testing. The circuit board for testing has through holes, and screws are passed through the through holes and connected to the fixing screw holes to fix the circuit board for testing to the fixed platform 4. A support rod 8 is provided at the top of the fixed platform 4. The axis of the support rod 8 is vertically set, and the fixing screw hole is set in the support rod 8, with the axis of the fixing screw hole parallel to the axis of the support rod 8. The support rod 8 can support the circuit board for testing from below, so that the circuit board for testing is suspended from the top of the fixed platform 4, preventing components such as capacitors on the circuit board for testing from protruding and causing the circuit board for testing to be uneven.
[0049] Example 2:
[0050] This embodiment 2 provides a crimping device for testing optical devices 9. Unlike embodiment 1, the top of the fixed platform 4 in this embodiment 2 is also provided with a groove.
[0051] The groove runs through both sides of the fixed platform 4, with the opening of the groove facing upward. The groove can reduce the weight of the fixed platform 4 and make it easier to insert fingers into the underside of the test circuit board, thus making it easier to remove or place the test circuit board with fingers.
[0052] Example 3:
[0053] This embodiment three provides a crimping device for testing optical devices 9. The difference between this embodiment three and the first embodiment is that the fixing part 2 is different.
[0054] like Figure 2 As shown, a sliding groove 22 is provided on the side of the fixing part 2 opposite to the positioning surface. The length direction of the sliding groove 22 is perpendicular to the positioning surface. A positioning plate is provided in the sliding groove 22 or at one end of the sliding groove 22. An internal threaded hole is provided on the positioning plate. A drive screw 23 adapted to the internal threaded hole is provided. One end of the drive screw 23 abuts against the housing of the optical device 9, which serves to press the housing of the optical device 9 from the side.
[0055] The drive screw 23 can directly abut against the housing of the optical device 9, or indirectly abut against the housing of the optical device 9.
[0056] like Figure 3 As shown, during indirect contact, a clamping block 24 is provided in the sliding groove 22, the drive screw 23 abuts against the clamping block 24, and the clamping block 24 abuts against the housing of the optical device 9.
[0057] like Figure 4 As shown, a buffer spring 25 can also be provided between the drive screw 23 and the clamping block 24. The buffer spring 25 is used to buffer and prevent damage to the housing of the optical device 9 caused by rigid clamping.
