Technical Field
[0001] This application relates to the field of electronic component manufacturing equipment technology, and more specifically, to a fixture transfer device for producing surface mount resistors. Background Technology
[0002] Chip resistors are one of the most commonly used passive electronic components in surface mount technology. They are formed by printing resistive paste or depositing metal thin films on a ceramic substrate, and the circuit connection is achieved by metal electrodes at both ends. They can be directly mounted on the surface of a PCB board.
[0003] The use of fixtures to transfer positions in the production of surface mount resistors is crucial for adapting to miniaturization characteristics, ensuring precise connection of automated processes, protecting products, and ensuring batch consistency. It is a key link in large-scale, high-quality production.
[0004] However, in the automated production process of surface mount resistors, the surface mount resistors need to be transferred between processes via a conveyor belt. However, due to the light weight of surface mount resistors, some surface mount resistors are easily affected by factors such as conveyor belt vibration and speed fluctuations during the conveyor belt process, resulting in positional deviations and difficulties in the subsequent clamping process.
[0005] In view of this, we propose a fixture transfer device for the production of surface mount resistors. Summary of the Invention

[0018] The present application will be further described in detail below with reference to the accompanying drawings.
[0019] Reference Figures 1-5This application discloses a fixture transfer device for producing surface mount resistors, comprising a workbench 1, a first support frame 2, a fixture mechanism 3, and a correction mechanism 4. A top plate 11 is fixedly connected to the top of the workbench 1, and a placement platform 12 is also fixedly connected to the top of the workbench 1, with the placement platform 12 positioned below the workbench 1. A conveyor belt 21 is fixedly connected to the top of the workbench 1 and mounted in the middle of the first support frame 2. The top plate 11 is positioned at the bottom, and the conveyor belt 21 is positioned on both sides for correcting misaligned surface mount resistors. The correction mechanism 4 includes two slidingly arranged first push plates 41 and second push plates 42, which are fixedly connected. The second push plate 42 is an inclined mechanism, positioned away from the placement platform 12. The first push plates 41 and 42 are driven by external force into the conveyor belt 21. The telescopic movement of the part; the correction mechanism 4 also includes two slide grooves 43 opened on the top of the workbench 1. The inner wall of the slide groove 43 is fixedly connected to a limit plate 44. The outer wall of the limit plate 44 is slidably connected to a second support frame 45. The top of the second support frame 45 is fixedly connected to two second push rods 46. The output end of the second push rod 46 is fixedly connected to a first connecting plate 47. The first connecting plate 47 is fixedly connected to the first push plate 41 and the second push plate 42. A fixing mechanism 5 is provided in the middle of the second support frame 45 for fixing the position of the second support frame 45 after sliding; the clamping mechanism 3 includes a mounting frame 31 fixed to the bottom of the top plate 11. The bottom of the mounting frame 31 is installed with a first push rod 32. The bottom of the top plate 11 is fixedly connected to a guide rail 33. The output shaft of the first push rod 32 is installed with a clamping body 34. The clamping body 34 and the guide rail 33 are slidably connected; First, the device is supported by a workbench 1. A top plate 11 fixed to the top of the workbench 1 is used to install the clamping mechanism 3. At the same time, a conveyor belt 21 is mounted on the first support frame 2 on the top of the workbench 1. The conveyor belt 21 can transport the chip resistors to the vicinity of the placement table 12. When the chip resistors deviate on the conveyor belt 21, multiple second push rods 46 are activated. The second push rods 46 of the correction mechanism 4 drive the first connecting plate 47, causing the first push plate 41 and the second push plate 42 to move telescopically towards the middle of the conveyor belt 21. Since the second push plate 42 is an inclined structure facing away from the placement table 12, with the help of the linear push of the first push plate 41 and the inclined guidance of the second push plate 42, the deviated chip resistors are corrected. The resistor is corrected to the center of the conveyor belt 21. Then, the first push rod 32 of the clamping mechanism 3 slides along the guide rail 33, driving the clamp body 34 to move above the conveyor belt 21, clamping the corrected chip resistor and transferring it to the placement table 12 for subsequent processing. This step solves the problem of chip resistors being easily deviated during transport, leading to inaccurate clamping and transfer, by the telescopic sliding of the first push plate 41 and the second push plate 42 on the correction mechanism 4. At the same time, the second push plate 42 in the correction mechanism 4 adopts an inclined structure and faces away from the placement table 12. It can not only push the deviated chip resistor back into place, but also achieve the orientation and straightening of the resistor through the inclined guide, avoiding structural damage to the chip resistor caused by hard pushing.
[0020] Reference Figures 1-5 The fixing mechanism 5 includes two counterweights 51 that slide within the second support frame 45. A plurality of fixing holes 52 are provided in the center of the limiting plate 44. Pins 53 are fixedly connected to the bottom of each counterweight 51, and the pins 53 are through-holes into the bottom of the second support frame 45. The pins 53 and fixing holes 52 are plugged into each other. A second connecting plate 54 is fixedly connected to the top of each counterweight 51. The bottom of the pins 53 has an arc-shaped structure. When the working position of the correction mechanism 4 needs to be adjusted, the second support frame 45 is pushed to slide along the limiting plate 44 in the top groove 43 of the worktable 1. Once the sliding position is reached... After the position is marked, the counterweight 51 of the fixing mechanism 5 will rely on its own weight to drive the pin 53 through the bottom of the second support frame 45 and insert it into the corresponding fixing hole 52 in the middle of the limiting plate 44. At the same time, the second connecting plate 54 on the top of the two counterweights 51 will drive the two pins 53 to move synchronously, ensuring the synchronization of the insertion of the pins 53. This step increases the flexibility of the correction mechanism 4 in use and can adapt to different usage scenarios. Through the gravity drive of the counterweight 51 and the insertion of the pins 53, the convenience of fixing the position of the second support frame 45 is improved.
[0021] Reference Figures 1-5 The second push rod 46 has a mounting piece 6 fixed to its side wall. The two mounting pieces 6 are set close to each other on one side. A torsion spring 61 is installed inside the mounting piece 6. A pressure plate 62 is installed on the outer wall of the torsion spring 61. The bottom of the pressure plate 62 is flush with the second connecting plate 54 after insertion and closure. During the process of the second push rod 46 driving the first connecting plate 47 to move, the torsion spring 61 inside the mounting part 6 fixed to the side wall of the second push rod 46 will drive the pressure plate 62 to maintain a rotational tendency, so that the bottom of the pressure plate 62 keeps in contact with and presses the top of the second connecting plate 54. Since the bottom of the pressure plate 62 is flush with the closed second connecting plate 54, it can form a vertical limit on the second connecting plate 54, preventing the counterweight 51 from moving upward. This step solves the problem that the vibration of the equipment operation can easily cause the pin 53 to fall out of the fixing hole 52, thereby causing the position of the correction mechanism 4 to shift, and further strengthens the fixing stability of the fixing mechanism 5.
[0022] Reference Figures 1-5 Two pressure plates 62 are fixed to the outer walls with pull ropes 63, and the second support frame 45 is fixed to the outer wall with a protrusion 48. When the position of the second support frame 45 needs to be adjusted again, the pull ropes 63 fixed to the outer walls of the two pressure plates 62 are pulled. The pull ropes 63 will drive the pressure plates 62 to rotate against the elastic force of the torsion spring 61, so that the pressure plates 62 are disengaged from the second connecting plate 54. Then, the pull ropes 63 are hung on the protrusion 48 on the outer wall of the second support frame 45, so that the two pressure plates 62 can be kept in the unfolded state, which makes it easy for the operator to push the second support frame 45 to adjust its position. This step, through the cooperation of the pull ropes 63 and the protrusion 48, realizes the maintenance of the unfolded state of the pressure plates 62, solves the problem that the pressure plates 62 continuously press against the second connecting plate 54 when adjusting the position of the second support frame 45, which causes inconvenience in operation, and improves the ease of operation of the position adjustment of the correction mechanism 4.
[0023] In summary, when the fixture transfer device for chip resistor production disclosed in this application is used, firstly, the device is supported by a workbench 1. The top plate 11 fixed to the top of the workbench 1 is used to install the fixture mechanism 3. At the same time, a conveyor belt 21 is assembled on the first support frame 2 on the top of the workbench 1. The conveyor belt 21 can transport the chip resistor to the vicinity of the placement table 12. When the chip resistor deviates on the conveyor belt 21, multiple second push rods 46 are activated. The second push rods 46 of the correction mechanism 4 drive the first connecting plate 47, which in turn drives the first push plate 41 and the second push plate 42 to move into the conveyor belt 21. The second push plate 42, being inclined and facing away from the placement table 12, is moved by the linear push of the first push plate 41 and the inclined guidance of the second push plate 42. This corrects the offset surface-mount resistor to the center of the conveyor belt 21. Subsequently, the first push rod 32 of the clamping mechanism 3 slides along the guide rail 33, moving the clamping body 34 above the conveyor belt 21. It clamps the corrected surface-mount resistor and transfers it to the placement table 12 for subsequent processing. When the working position of the correction mechanism 4 needs adjustment, the second support frame 45 is pushed along the limiting plate 4 in the top groove 43 of the worktable 1. 4. Sliding: After sliding to the target position, the counterweight 51 of the fixing mechanism 5 will rely on its own weight to drive the pin 53 through the bottom of the second support frame 45 and insert it into the corresponding fixing hole 52 in the middle of the limiting plate 44. At the same time, the second connecting plate 54 on the top of the two counterweights 51 will synchronously drive the two pins 53 to move, ensuring the synchronous insertion of the pins 53. During the process of the second push rod 46 driving the first connecting plate 47 to move, the torsion spring 61 inside the mounting part 6 fixed to the side wall of the second push rod 46 will drive the pressure plate 62 to maintain a rotational trend, so that the bottom of the pressure plate 62 and the top of the second connecting plate 54 are kept in contact. When the pressure plate 62 is in contact and pressed, since the bottom of the pressure plate 62 is flush with the closed second connecting plate 54, it can form a vertical limit on the second connecting plate 54, preventing the counterweight 51 from moving upward. When it is necessary to readjust the position of the second support frame 45, pull the pull rope 63 fixed to the outer wall of the two pressure plates 62. The pull rope 63 will drive the pressure plate 62 to rotate against the elastic force of the torsion spring 61, so that the pressure plate 62 is disengaged from the second connecting plate 54. Then, hang the pull rope 63 on the protrusion 48 on the outer wall of the second support frame 45, so that the two pressure plates 62 can remain in the unfolded state, making it convenient for the operator to push the second support frame 45 to adjust its position.
