Description

Technical Field

[0001] This application relates to the field of SMT capping technology, and more specifically, to an automatic SMT capping pickup machine. Background Technology

[0002] In the SMT production process of flexible printed circuit boards, in order to prevent the mounted components from moving during production, pressure caps are usually installed before reflow oven. The pressure caps are designed with corresponding pressure pins to hold the components in place.

[0003] Currently, the operation of removing the caps after the reflow oven is done manually. However, the temperature of the reflow oven is as high as 250-270 degrees Celsius, and the SMT caps are still more than 200 degrees Celsius after passing through the oven. Even if the personnel removing the caps wear gloves and other protective equipment, there is still a risk of being burned during the manual removal of the caps, which threatens the safety of the personnel.

[0004] Furthermore, manual cap removal is inefficient, affecting production efficiency and increasing production costs. In addition, manual operation may damage the cap or other equipment due to improper operation, affecting product quality and the normal operation of the equipment.

[0005] Therefore, there is a need for a device that can automatically pick up SMT caps to solve the safety hazards and inefficiency of manual cap picking, improve production safety and efficiency, and reduce production costs.

[0006] Therefore, this application proposes an automatic SMT capping machine to solve the aforementioned problems. Utility Model Content

[0007] To address the aforementioned issues, this application provides an automatic SMT capping machine.

[0008] The SMT capping automatic pickup machine provided in this application adopts the following technical solution:

[0009] SMT capping automatic pick-up machine, including:

[0010] The facility includes a feeding device, a material handling device, and a tilting device, with the feeding device and the tilting device placed on the left and right sides of the material handling device, respectively.

[0011] The feeding equipment includes a feeding platform, on the top of which are provided several aluminum profiles, and on the opposite sides of adjacent aluminum profiles are provided a conveyor belt. A carrier plate is placed on the conveyor belt, and a pressure cap body is engaged on the carrier plate. The pressure cap body is provided with a buckle that engages with the carrier plate.

[0012] The material handling equipment includes a workbench. A first linear motor module is mounted on the top of the workbench. A connecting plate is fixedly connected to the slider of the first linear motor module. A vertically downward sliding cylinder is fixedly connected to the connecting plate. A fixed plate is horizontally connected to the slide of the sliding cylinder. A clamping cylinder and a release cylinder are symmetrically arranged at the top and bottom of the fixed plate, respectively. The release cylinder is used to unlock the buckle. A pressure plate is provided on the piston rod of the release cylinder. In the initial state, the release cylinder is in the extended state.

[0013] The flipping device includes a second linear cylinder module disposed on the upper surface of the feeding platform. A slide plate is fixedly connected to the slider of the second linear cylinder module. A rotary cylinder and a bearing seat are disposed on the upper surface of the slide plate. The end of the rotating shaft of the rotary cylinder cooperates with the bearing seat. The rotation angle of the rotary cylinder is 180°. A rotary bearing is fixedly disposed on the rotating shaft. Limiting cylinders electrically connected to the rotary cylinder are symmetrically disposed on the upper surface of the rotary bearing. Limiting blocks are disposed on the piston rod of the limiting cylinder.

[0014] The flipping device is connected to a conveyor platform.

[0015] Furthermore, the piston rod of the clamping cylinder is provided with grippers, each gripper being a symmetrically arranged inverted F-shaped structure, with adjacent grippers having opposite clamping directions.

[0016] Through the above technical solution, the inverted F-shaped gripper can make better contact with the cap, increasing the contact area between the gripper and the cap, thereby improving the stability and reliability of clamping, preventing the cap from shaking or falling during clamping, and ensuring the accuracy and efficiency of material handling; the symmetrically arranged gripper structure is simple, easy to manufacture and install, reduces the manufacturing cost of the equipment, and also facilitates the maintenance and replacement of the gripper, improving the overall performance and service life of the equipment.

[0017] Furthermore, the feeding device also includes a horizontally arranged positioning cylinder and a vertically arranged lifting cylinder. The lifting cylinders are symmetrically arranged in the feeding device. The piston rod of the lifting cylinder is fixedly connected to the positioning cylinder. A stop block is provided on the piston rod of the positioning cylinder. The distance between adjacent positioning cylinders is greater than the length of the carrier plate.

[0018] The above technical solution can effectively control the transmission of the carrier plate. The positioning cylinder can block the movement of the carrier plate or center the carrier plate through the stop block so that the material picking equipment can accurately position it. In actual production, this design can avoid the carrier plate from getting confused during the transmission process and ensure the accuracy and stability of the material supply.

[0019] Furthermore, the block is provided with a concave corner structure, and when the block blocks the carrier plate, the concave corner fits against the side and top of the carrier plate.

[0020] Through the above technical solution, this design makes the contact between the stop and the carrier plate closer, which can more effectively block the movement of the carrier plate and ensure the stability of the carrier plate during the transmission process; the inside corner structure can better match the shape of the carrier plate, increase the friction between the stop and the carrier plate, prevent the carrier plate from sliding or deviating when blocked, and improve the reliability of the feeding equipment.

[0021] Furthermore, the slide plate is symmetrically provided with several buffer rubber heads around the pivot axis, and the buffer rubber heads are located within the rotation range of the rotating load.

[0022] Through the above technical solutions, the buffer rubber head can effectively reduce the impact and collision of the rotating load on other components during rotation, protect the various parts of the equipment, and extend the service life of the equipment. When the rotating load is rotating, the buffer rubber head can play a role in buffering and shock absorption, making the rotation of the rotating load more stable and reducing vibration and noise during equipment operation.

[0023] Furthermore, the rotating bearing is a contoured structure that matches the pressure cap body.

[0024] Through the above technical solutions, the contouring structure can better fit the cap body, ensuring the stability of the cap under rotational load. During the flipping process, the rotational load of the contouring structure can more accurately fix the cap, preventing displacement or falling off during the flipping process, and ensuring the smooth progress of the flipping operation. Moreover, the contouring structure can be designed according to the shape of the cap body, improving the equipment's adaptability to caps of different shapes, increasing the equipment's versatility, reducing the cost of changing different equipment due to different cap shapes, improving the efficiency of equipment use, and also facilitating the placement and removal of caps, thus improving production efficiency.

[0025] Furthermore, the conveying platform is uniformly equipped with several downward-facing cooling fans.

[0026] The above technical solution addresses the issue of high temperatures in SMT caps after reflow oven reflow. The cooling fans quickly lower the cap's temperature, preventing adverse effects on subsequent operations and equipment. The downward-facing airflow design allows for more direct cooling of the caps, improving cooling efficiency. The evenly positioned cooling fans ensure that all parts of the cap receive adequate cooling.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] (1) Through the coordinated work of various devices, the feeding equipment conveys the carrier plate and the pressure cap in an orderly manner, the picking equipment picks up, unfastens and clamps the material accurately, and the flipping equipment flips the surface effectively, thus avoiding manual operation in a high-temperature environment, reducing the risk of burns and ensuring personnel safety.

[0029] (2) Automated operation replaces manual picking, improves the speed and accuracy of capping, avoids the instability of manual operation, thereby greatly improving production efficiency, making the production process smoother, and ensuring the continuity of production.

[0038] Example:

[0039] The following is in conjunction with the appendix Figure 1 -4 provides further detailed description of this application.

[0040] This application discloses an automatic SMT capping machine, including:

[0041] The feeding device, the material handling device, and the tilting device are placed on the left and right sides of the material handling device, respectively.

[0042] The feeding equipment includes a feeding platform 1, a number of aluminum profiles 2 are provided on the top of the feeding platform 1, a conveyor belt is provided on the opposite side of the adjacent aluminum profiles 2, a carrier plate 3 is placed on the conveyor belt, a pressure cover body 4 is engaged on the carrier plate 3, and the pressure cover body 4 is provided with a buckle 5 that engages with the carrier plate 3.

[0043] The material handling equipment includes a workbench 6, with a first linear motor module 7 mounted on top of the workbench 6. A connecting plate is fixedly connected to the slider of the first linear motor module 7, and a vertically downward sliding cylinder 8 is fixedly connected to the connecting plate. A fixing plate 9 is horizontally connected to the slide of the sliding cylinder 8. A clamping cylinder 10 and a release cylinder 11 are symmetrically arranged at the top and bottom of the fixing plate 9, respectively. The release cylinder 11 is used to unlock the buckle 5. A pressure plate is provided on the piston rod of the release cylinder 11. In the initial state, the release cylinder 11 is in the extended state. The buckle is a common forward and reverse pry buckle. The pressure plate moves to press the top of the buckle, which can disengage the pressure cover from the plate.

[0044] The flipping device includes a second linear cylinder module 12 disposed on the upper surface of the feeding platform 1. A slide plate 13 is fixedly connected to the slider of the second linear cylinder module 12. A rotary cylinder 14 and a bearing seat 15 are disposed on the upper surface of the slide plate 13. The end of the rotating shaft 16 of the rotary cylinder 14 is engaged with the bearing seat 15. The rotation angle of the rotary cylinder 14 is 180°. A rotary bearing 17 is fixedly disposed on the rotating shaft 16. A limit cylinder 18 electrically connected to the rotary cylinder 14 is symmetrically disposed on the upper surface of the rotary bearing 17. A limit block 19 is disposed on the piston rod of the limit cylinder 18.

[0045] The flipping device is connected to a conveyor platform 20.

[0046] See Figure 1 , Figure 3 and Figure 4 The piston rod of the clamping cylinder 10 is equipped with grippers 21, each gripper 21 being a symmetrically arranged inverted F-shape, with adjacent grippers 21 having opposite clamping directions. The inverted F-shaped grippers 21 can better contact the pressure cap, increasing the contact area between the grippers 21 and the pressure cap, thereby improving the stability and reliability of clamping, preventing the pressure cap from shaking or falling off during clamping, and ensuring the accuracy and efficiency of material handling. The symmetrically arranged grippers 21 have a simple structure, are easy to manufacture and install, reduce the manufacturing cost of the equipment, and also facilitate the maintenance and replacement of the grippers 21, improving the overall performance and service life of the equipment.

[0047] See Figure 1 and Figure 2 The feeding device also includes a horizontally positioned positioning cylinder 22 and a vertically positioned lifting cylinder 23. The lifting cylinders 23 are symmetrically arranged inside the feeding device. The piston rod of the lifting cylinder 23 is fixedly connected to the positioning cylinder 22. The piston rod of the positioning cylinder 22 is equipped with a stop block 24. The distance between adjacent positioning cylinders 22 is greater than the length of the carrier plate 3. This can effectively control the transmission of the carrier plate 3. The positioning cylinder 22 can block the movement of the carrier plate 3 or center the carrier plate 3 through the stop block 24 so that the material picking device can accurately position it. In actual production, this design can avoid the carrier plate 3 from becoming disordered during transmission, ensuring the accuracy and stability of the feeding.

[0048] See Figure 2 The stop block 24 is provided with an inside corner structure. When the stop block 24 blocks the carrier plate 3, the inside corner fits against the side and top of the carrier plate 3. This design makes the contact between the stop block 24 and the carrier plate 3 more compact, which can more effectively block the movement of the carrier plate 3 and ensure the stability of the carrier plate 3 during the transmission process. The inside corner structure can better match the shape of the carrier plate 3, increase the friction between the stop block 24 and the carrier plate 3, prevent the carrier plate 3 from sliding or shifting when blocked, and improve the reliability of the feeding equipment.

[0049] See Figure 3 and Figure 4 Several buffer rubber heads 25 are symmetrically arranged on the slide plate 13 with the rotating shaft 16 as the center. The buffer rubber heads 25 are located within the rotation range of the rotating bearing 17. The setting of the buffer rubber heads 25 can effectively reduce the impact and collision of the rotating bearing 17 on other components during rotation, protect the various components of the equipment, and extend the service life of the equipment. When the rotating bearing 17 rotates, the buffer rubber heads 25 can play a role in buffering and shock absorption, making the rotation of the rotating bearing 17 more stable and reducing the vibration and noise during the operation of the equipment.

[0050] See Figure 3 and Figure 4 The rotating bearing 17 is a contoured structure that matches the cap body 4. The contoured structure can better fit the cap body 4, ensuring the stability of the cap on the rotating bearing 17. During the flipping process, the contoured rotating bearing 17 can more accurately fix the cap, preventing the cap from shifting or falling off during the flipping process, ensuring the smooth progress of the flipping operation. Moreover, the contoured structure can be designed according to the shape of the cap body 4, improving the equipment's adaptability to caps of different shapes, increasing the equipment's versatility, reducing the cost of changing different equipment due to different cap shapes, improving the equipment's efficiency, and also facilitating the placement and removal of the cap, thus improving production efficiency.

[0051] Furthermore, several downward-facing cooling fans 26 are evenly mounted on the conveyor platform 20. Because the SMT caps are at a high temperature after reflow oven reflow, the cooling fans 26 can quickly reduce the temperature of the caps, preventing high temperatures from affecting subsequent operations and equipment. The downward-facing airflow design allows the cooling air to act more directly on the caps, improving the cooling effect. The evenly mounted cooling fans 26 ensure that all parts of the caps receive sufficient cooling.

[0052] The implementation principle of the SMT capping automatic pickup machine in this application embodiment is as follows: First, the conveyor belt of the feeding equipment transports the carrier plate 3 containing the capping body 4. The positioning cylinder 22 and the lifting cylinder 23 work together to position and block the carrier plate 3, so that the carrier plate 3 accurately stops at the designated position of the feeding table 1.

[0053] The first linear motor module 7 of the material handling equipment drives the slide cylinder 8 to move above the cap body 4. The slide cylinder 8 descends, the release cylinder 11 unlocks the buckle 5 between the cap body 4 and the carrier plate 3, the gripper 21 of the clamping cylinder 10 clamps the cap body 4, and then the slide cylinder 8 rises. The first linear motor module 7 transports the cap body 4 to the flipping equipment.

[0054] The second linear cylinder module 12 of the flipping device moves the slide plate 13 to the bottom of the material receiving device to receive the cap body 4. The limiting cylinder 18 extends the limiting block 19 to restrict the cap. Then, the rotary cylinder 14 drives the rotary bearing 17 to rotate 180° to flip the cap body 4. The limiting cylinder 18 and the limiting block 19 play the role of positioning and preventing the cap body 4 from falling during the flipping process. The buffer rubber head 25 ensures the stability of the flipping process. After the rotary cylinder 14 rotates 180°, it sends a command to the limiting cylinder 18 to release the limiting block 19, and then the cap falls into the conveyor platform 20 under gravity.

[0055] Finally, the flipped cap body 4 is placed on the docking conveyor platform 20. The cooling fan 26 on the conveyor platform 20 cools the cap body 4. Then the cap body 4 is conveyed to the cap loading station to complete the automatic picking and flipping operation of the entire SMT cap.

[0056] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
