Description

Technical Field

[0001] This invention relates to the field of circuit board via plugging technology, and more specifically to an automatic loading and unloading vacuum via plugging device. Background Technology

[0002] PCB circuit boards are the core carriers for electrical connections of electronic components. As electronic products rapidly develop towards high density and high integration, the resin plugging process of PCB boards has become a key process to ensure their electrical performance and structural reliability. Among them, vacuum plugging technology has become the mainstream plugging process in the PCB processing industry because it can effectively avoid air bubbles in the plugging holes and improve the fullness of resin in the holes.

[0003] Currently, most conventional vacuum plugging equipment in the industry uses manual methods to complete the loading and unloading of PCB boards. This requires dedicated personnel at the loading and unloading station to perform operations such as picking up and placing boards, transferring them, and stacking them. However, the efficiency of manual operation is greatly affected by the operator's skill level, working hours, and working condition, making it difficult to consistently match the continuous processing rhythm of the vacuum plugging machine and significantly limiting the processing capacity of the entire production line. Furthermore, during the manual board picking and unloading process, problems such as PCB board scratches, fingerprint and oil stains, and bending damage are very likely to occur, directly leading to a decrease in product yield and increasing the company's production costs.

[0004] Therefore, the present invention provides an automatic loading and unloading vacuum plugging device to solve the above problems. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, the present invention provides an automatic loading and unloading vacuum plugging device to solve the problems of high cost, low efficiency and easy damage to the board by manual loading and unloading in the prior art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] An automatic loading and unloading vacuum plugging device includes a vacuum plugging machine and two storage mechanisms. Two robotic arms are fixedly installed on the vacuum plugging machine, and each robotic arm corresponds to one of the storage mechanisms.

[0008] The storage mechanism includes a storage frame, inside which a first support plate and a plurality of second support plates are slidably connected, with the second support plates located above the first support plate. First connecting columns are fixedly connected between the first and second support plates and between two adjacent second support plates. Clamping components are provided above the first and second support plates. Releasing limiting components are provided on both side walls of the storage frame near the top. A driving component is provided on one side of the storage frame.

[0009] Preferably, the clamping assembly includes two first support plates fixedly connected to the upper surface of the first support plate. Each of the two first support plates has a first spring fixedly connected to its opposite side. The other end of the first spring is fixedly connected to a first pull plate. A second connecting post is fixedly connected to the outer surface of the first pull plate. The end of the second connecting post away from the first pull plate slides through the first support plate and is fixedly connected to a clamping plate.

[0010] Preferably, an anti-slip pad is fixedly installed on the side of the clamp away from the first support plate.

[0011] Preferably, an L-shaped plate is fixedly connected to the side of the first pull plate away from the first support plate, and a first wedge plate is fixedly connected to the outer surface of the L-shaped plate.

[0012] Preferably, the release limiting component includes a second support plate fixedly connected to the inner wall of the storage frame. A second wedge plate corresponding to the first wedge plate is fixedly connected to the outer surface of the second support plate. A baffle is provided on the upper surface of the second wedge plate. An insert plate is fixedly connected to the outer surface of the baffle plate. A slot for the insert plate is opened inside the second support plate. The top end of the insert plate is inserted into the inside of the slot.

[0013] Preferably, the insert plate has an inclined groove and a limiting hole inside. The depth of the inclined groove gradually decreases from bottom to top. The limiting hole is located at the shallowest end of the inclined groove and is connected to the inclined groove.

[0014] Preferably, the second support plate has a groove inside, and a second pull plate is slidably connected inside the groove. A second spring and a limiting rod are fixedly connected to the outer surface of the second pull plate. The other end of the second spring is fixedly connected to the inner wall of the groove. A circular hole adapted to the limiting rod is opened inside the second support plate. The other end of the limiting rod slides through the circular hole and is inserted into the inside of the limiting hole.

[0015] Preferably, the drive assembly includes a housing fixedly connected to one side of the storage frame, a threaded rod rotatably mounted inside the housing, a motor fixedly mounted on the bottom surface of the housing, the output end of the motor being fixedly connected to the bottom end of the threaded rod, a threaded plate being threadedly connected to the outer surface of the threaded rod, the threaded plate being slidably connected to the inside of the housing, a slider being slidably connected to the outer surface of the threaded plate, the slider being slidably connected to the inside of the storage frame, and the side of the slider away from the threaded plate being fixedly connected to a first bearing plate.

[0018] The beneficial effects of this invention are as follows:

[0019] 1. This invention, by configuring a robotic arm on the vacuum plugging machine that corresponds one-to-one with the storage mechanism, and in conjunction with a multi-layer carrier plate structure that can be raised and lowered synchronously, realizes the fully automated loading and unloading operation of PCB board plugging processing. The entire process does not require manual intervention in board handling, which greatly reduces the labor cost of the production line. At the same time, it avoids problems such as PCB board contamination, scratches, and bending damage caused by manual operation from the root, and effectively improves the product processing yield.

[0020] 2. This invention, by setting an elastic clamping component on the carrier plate and cooperating with the release limiting component at the top of the storage frame, can automatically release the clamping of the PCB board when the carrier plate rises to the material handling station, and automatically complete the clamping and fixing of the PCB board when the carrier plate descends to the storage station. No additional independent drive and control components are required. The structure is simple and reliable, which not only ensures the stability of the PCB board during lifting and transportation, preventing the board from shifting and falling off, but also does not interfere with the automatic material handling operation of the robot, perfectly adapting to the rhythm of automated operation.

[0030] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0031] As attached Figure 1-8 As shown, an automatic loading and unloading vacuum plugging device includes a vacuum plugging machine 1 and two storage mechanisms. Two robotic arms 2 are fixedly installed on the vacuum plugging machine 1, and each robotic arm 2 corresponds to one of the storage mechanisms. The two robotic arms 2 correspond to the loading storage mechanism and the unloading storage mechanism, respectively, and can independently complete the automatic loading and unloading of PCB boards to be processed and the unloading and stacking of PCB boards after processing, realizing the automation of the entire plugging process without manual intervention.

[0032] The storage mechanism includes a storage frame 3, inside which a first support plate 10 and a plurality of second support plates 11 are slidably connected, and the second support plates 11 are located above the first support plate 10. The first support plate 10 and the second support plate 11, as well as two adjacent second support plates 11, are all fixedly connected by a first connecting column 12. Through the rigid connection of the first connecting column 12, the first support plate 10 and all the second support plates 11 form a synchronous lifting and lowering whole, ensuring that the relative position of each layer of support plate remains unchanged during the lifting and lowering process, which facilitates the robot arm 2 to accurately position and pick up and put down the plate parts.

[0033] Clamping assemblies are provided above the first support plate 10 and the second support plate 11 to clamp and fix the PCB board placed on the support plate, so as to avoid displacement, slippage, and collision of the board during lifting and transportation. The clamping assembly includes two first support plates 13 fixedly connected to the upper surface of the first support plate 10. The two first support plates 13 are symmetrically arranged along the center line of the support plate to ensure balanced clamping force on the PCB board. A first spring 14 is fixedly connected to the side of the two first support plates 13 that is far away from each other. A first pull plate 15 is fixedly connected to the other end of the first spring 14. A second connecting post 16 is fixedly connected to the outer surface of the first pull plate 15. The end of the second connecting post 16 that is far away from the first pull plate 15 slides through the first support plate 13 and is fixedly connected to a clamping plate 17. Under natural conditions without external force, the rebound force of the first spring 14 can drive the two clamping plates 17 to move closer to each other through the first pull plate 15 and the second connecting post 16, thereby stably clamping and fixing the PCB board.

[0034] An anti-slip pad is fixedly installed on the side of the clamping plate 17 away from the first support plate 13. The anti-slip pad can be made of elastic and frictional materials such as rubber and silicone. It can not only increase the friction between the clamping plate 17 and the PCB board and further enhance the stability of clamping, but also prevent the clamping plate 17 from directly contacting and scratching the surface of the PCB board through elastic buffering, thus protecting the integrity and appearance quality of the board.

[0035] An L-shaped plate 18 is fixedly connected to the side of the first pull plate 15 away from the first support plate 13. A first wedge plate 19 is fixedly connected to the outer surface of the L-shaped plate 18. The inclined surface of the first wedge plate 19 faces the inner side of the storage frame 3 and is used to cooperate with the release limit component. Through the pressing transmission of the inclined surface, the clamping state of the clamping component is automatically switched.

[0036] The storage frame 3 has release components installed on both side walls near the top. These components automatically release the clamping restraints on the PCB board when the support plate rises to the material handling / unloading station, allowing space for the robotic arm 2 to handle the board. The release components include a second support plate 20 fixedly connected to the inner wall of the storage frame 3. A second wedge plate 21 corresponding to the first wedge plate 19 is fixedly connected to the outer surface of the second support plate 20. The inclined surface of the second wedge plate 21 matches the inclined surface of the first wedge plate 19. During the rising of the support plate, the inclined surface of the first wedge plate 19 and the inclined surface of the second wedge plate 21... The inclined surfaces contact and press against each other, which can drive the first pull plate 15 to move away from the first support plate 13, thereby driving the clamping plate 17 to move outward and release the clamping of the PCB board. The upper surface of the second wedge plate 21 is provided with a baffle 22, and the outer surface of the baffle 22 is fixedly connected with an insert plate 23. The interior of the second support plate 20 is provided with a slot for the insert plate 23, and the top of the insert plate 23 is inserted into the interior of the slot. The baffle 22 can limit and block the first wedge plate 19 on the upper second carrier plate 11, ensuring that the carrier plates of different layers can complete the switching of clamping states in sequence according to the operation order, avoiding operation chaos.

[0037] The insert plate 23 has an inclined groove 24 and a limiting hole 25 inside. The depth of the inclined groove 24 gradually decreases from bottom to top. The limiting hole 25 is located at the shallowest end of the inclined groove 24 and communicates with it. The second support plate 20 has a sliding groove inside. A second pull plate 27 is slidably connected inside the sliding groove. A second spring 26 and a limiting rod 28 are fixedly connected to the outer surface of the second pull plate 27. The other end of the second spring 26 is fixedly connected to the inner wall of the sliding groove. The second support plate 20 has a circular hole inside that matches the limiting rod 28. The other end of the limiting rod 28 slides through the circular hole and is inserted into the groove. Inside the limiting hole 25, when installing the baffle 22, simply insert the insert plate 23 into the slot. During the insertion of the insert plate 23, the inclined groove 24 will gradually squeeze the limiting rod 28, causing the limiting rod 28 to move outward and stretch the second spring 26. When the insert plate 23 is fully inserted into the slot, the limiting rod 28 is concentric with the limiting hole 25. At this time, under the action of the second spring 26, the limiting rod 28 will be inserted into the limiting hole 25, completing the limiting and fixing of the insert plate 23 and the baffle 22. When the baffle 22 needs to be removed, simply pull the second pull plate 27 outward to drive the limiting rod 28 out of the limiting hole 25, completing the unlocking. The operation is simple and convenient.

[0038] A drive assembly is provided on one side of the storage frame 3 to drive the first support plate 10 and all the second support plates 11 to rise and fall synchronously, accurately adjust the height position of the support plate, and adapt to the working position of the robot arm 2.

[0039] The drive assembly includes a housing 6 fixedly connected to one side of the storage frame 3. A threaded rod 7 is rotatably mounted inside the housing 6. A motor 8 is fixedly mounted on the bottom surface of the housing 6. The output end of the motor 8 is fixedly connected to the bottom end of the threaded rod 7. A threaded plate 9 is threadedly connected to the outer surface of the threaded rod 7. The threaded plate 9 is slidably connected to the inside of the housing 6. A slider is slidably connected to the outer surface of the threaded plate 9. The slider is slidably connected to the inside of the storage frame 3, and the side of the slider away from the threaded plate 9 is fixedly connected to the first bearing plate 10. When the motor 8 rotates, it can drive the threaded rod 7 to rotate synchronously. Then, through the threaded engagement, it drives the threaded plate 9 to rise and fall stably along the axial direction of the threaded rod 7. Finally, through the slider, it drives the first bearing plate 10 and all the second bearing plates 11 to rise and fall synchronously, realizing the precise adjustment of the bearing plate height. This drive structure has stable transmission and high control precision, and can accurately match the working position of the robot arm 2 to ensure the accuracy of the plate picking and placing operation.

[0040] The bottom surface of the storage frame 3 is fixedly equipped with multiple self-locking casters 4. The self-locking casters 4 make it easy for the staff to push the storage frame 3 to complete the transfer. After the storage frame 3 is moved to the designated work position, the casters can be locked by the self-locking structure to ensure the stability of the position of the storage frame 3 and avoid the storage frame shifting during the operation, which would affect the accuracy of the robot's picking and placing of the plate.

[0041] The vacuum plugging machine 1 is fixedly connected to a positioning plate 5, and the positioning plate 5 is integrally formed with a positioning groove that matches the housing 6. When the storage frame 3 moves to the working position of the vacuum plugging machine 1, the housing 6 can be inserted into the positioning groove of the positioning plate 5 to quickly complete the positioning of the storage mechanism, ensuring the relative position of the storage mechanism and the robot 2 is accurate, and avoiding the problem of the robot failing to pick up or put down the plate due to the position deviation of the storage mechanism.

[0042] Working principle

[0043] Before operating the equipment, the PCB board to be processed is first prepared for loading: the PCB board to be processed is placed in sequence on the first support plate 10 and each of the second support plates 11 inside one of the storage frames 3 (loading storage frames). Under the action of the rebound force of the first spring 14, the two clamping plates 17 move closer to each other and clamp the PCB board stably and fix it on the support plate. At this time, the first support plate 10 and all the second support plates 11 are in the low position inside the storage frame 3, and the loading preparation is completed.

[0044] Then, the loading storage frame is pushed to the corresponding positioning plate 5 on the vacuum plugging machine 1, so that the housing 6 of the storage frame 3 is inserted into the positioning groove of the positioning plate 5, completing the positioning and fixing of the loading storage mechanism. At the same time, the self-locking caster 4 is locked to ensure the stability of the position of the storage frame 3 during operation. Meanwhile, another empty storage frame 3 (unloading storage frame) is pushed to another positioning plate 5 on the vacuum plugging machine 1 to complete the positioning and locking, which is used to store the processed PCB board. The motor 8 of the unloading storage frame is controlled to rotate forward, driving the threaded rod 7 to rotate, so that the threaded plate 9 drives the first bearing plate 10 to rise to the maximum stroke. At this time, all the second bearing plates 11 are in the high position above the storage frame 3, waiting for the unloading operation.

[0045] When the equipment starts operating, the motor 8 of the loading and storage frame is first reversed, which drives the threaded rod 7 to rotate in the opposite direction. Then, the threaded plate 9 drives the first bearing plate 10 and all the second bearing plates 11 to rise synchronously. When the uppermost second bearing plate 11 rises to the top material picking station of the storage frame 3, the first wedge plate 19 on the second bearing plate 11 contacts the baffle 22. As the bearing plate continues to rise, the baffle 22 squeezes the first wedge plate 19, which drives the first pull plate 15 to move outward and stretches the first spring 14. At the same time, the second connecting column 16 drives the two clamping plates 17 to move away from each other, automatically releasing the clamping limit of the PCB board on this layer. At this time, the corresponding loading robot 2 is controlled to take off the PCB board to be processed on the bearing plate and place it in the processing station of the vacuum plugging machine 1 for plugging processing.

[0046] After the PCB board of the current layer is picked up, the motor 8 of the loading and storage frame continues to reverse, driving the second carrier plate 11 of the next layer to rise to the picking station. The clamping, releasing and picking operations are repeated, and so on, to complete the continuous loading of all PCB boards to be processed, and stably match the processing rhythm of the vacuum plugging machine 1.

[0047] Meanwhile, after the vacuum plugging machine 1 completes the plugging of the PCB board, it controls the corresponding unloading robot 2 to take the processed PCB board out of the vacuum plugging machine 1 and place it on the first support plate 10 of the unloading storage frame. Then, it controls the motor 8 of the unloading storage frame to rotate forward, driving the first support plate 10 to move downward. When the first wedge plate 19 on the support plate of this layer descends to the point of disengagement from the second wedge plate 21, the two clamping plates 17 move closer to each other under the rebound action of the first spring 14, automatically clamping and fixing the processed PCB board to prevent the board from shifting or falling off during storage. Then, the motor 8 continues to rotate forward, driving the next layer of second support plate 11 to descend to the unloading station. The above unloading and clamping and fixing operations are repeated, and so on, to complete the continuous unloading and stacking operation of all processed PCB boards.

[0048] Once all the PCBs in a loading storage box have been processed, or the PCBs in a unloading storage box are stacked, simply unlock the self-locking caster wheel 4, push the full / empty storage box away from the workstation, and replace it with a new storage box with ready materials. There is no need to stop the machine and wait, which can realize continuous processing operations on the production line.
