[0002] The placement machine, also known as the placement machine, is placed after the dispensing machine or screen printer in the production line. It is a device that accurately places surface mount components on the PCB pads by moving the placement head.

[0003] The existing patent (publication number: CN219437493U) discloses a material unloading mechanism for a placement machine, including a mounting frame, a material rack is provided on the top of the inner wall of the mounting frame, a conveying mechanism is provided on the top of the mounting frame, the conveying mechanism includes two movable blocks, a groove is provided on the top of the mounting frame, a screw is rotatably connected between the inner walls of the groove, two nut seats are threadedly connected on the screw, the upper surface of the nut seat is fixedly connected to the lower surface of one end of the movable block, and a transmission mechanism is provided on the movable block.

[0004] The above-mentioned comparative document points out that the device moves the top of the mounting bracket to the discharge end of the circuit board conveyor belt, and then rotates the adjusting screw to cause the nut seats at both ends to move in opposite directions along the screw, driving the two nut seats to slide in the inner cavity of the groove.

However, the device is only equipped with one material rack, which limits its ability to operate continuously. On an automated production line, stopping for material replacement will significantly affect the overall production efficiency and increase production costs. When this only material rack is full or exhausted, the machine must be stopped to replace or reload materials, which will cause production interruptions and thus affect efficiency. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the present application provides a material unloading device for a placement machine, which has advantages such as continuous production, and solves the problem that the device is only equipped with one material rack, which limits its ability to operate continuously. On an automated production line, stopping to change materials will significantly affect the overall production efficiency and increase production costs. When this single material rack is full or exhausted, the machine must be stopped to replace or reload the material, which will cause production interruptions and thus affect efficiency.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a unloading device of a placement machine comprises a base plate, four discharge boxes and four lifting plates, the upper end of the base plate is fixedly connected to a swivel and an electric turntable, the upper end of the swivel and the electric turntable is fixedly connected to a turn plate, both sides of the outer surface of the turn plate are fixedly connected to a plurality of frames arranged in a ring array, the interior of the plurality of frames are rotatably connected to two mirror-distributed threaded rods, the upper ends of the plurality of frames are fixedly connected to two mirror-distributed first motors, both sides of the inner walls of the four discharge boxes are fixedly connected to a plurality of discharge plates arranged in a linear array, the bottom ends of the four discharge boxes are fixedly connected to a base, two fixed plates are fixedly connected to both sides of the four lifting plates, threaded holes are provided inside the four fixed plates, four positioning columns arranged in a rectangular array are fixedly connected to the upper ends of the four lifting plates, and magnets are fixedly connected to the upper ends of the four lifting plates.

[0007] Through the above scheme, the device realizes the automatic rotation and lifting of the discharge box and the lifting plate through the drive of the electric turntable and the first motor. This automated design significantly improves production efficiency, reduces manual intervention, and reduces labor intensity. The discharge box adopts a modular design, which is convenient for replacement and unloading. By adjusting the rotation direction and speed of the threaded rod, the lifting height of the lifting plate can be accurately controlled to drive the lifting and lowering of the discharge box. Through the design of the swivel and the electric turntable, multiple discharge boxes can be unloaded in turn in a limited space, thereby improving space utilization. The addition of magnets may be used to provide additional stability or fixing when the lifting plate is docked with the base or other docking components, thereby enhancing the overall stability and reliability of the device.

[0008] Furthermore, four positioning holes arranged in a rectangular array are provided at the bottom ends of the four bases, four mounting holes are provided at the bottom ends of the four bases, multiple positioning columns are slidably set inside the positioning holes, and four magnets are slidably set inside the mounting holes.

[0009] Through the above scheme, the sliding cooperation between the positioning column and the positioning hole provides more precise positioning for the connection between the lifting plate and the base. This design reduces the shaking and deviation during the lifting process, improves the accuracy and stability of the blanking, and the sliding setting of the magnet in the mounting hole is used to provide additional fixing force. The sliding positioning column and magnet make the installation and disassembly between the lifting plate and the base easier. This design facilitates the maintenance of the device and the process of replacing parts.

[0010] Furthermore, the outer wall of the bottom plate is fixedly connected to an extension plate, one side of the upper end of the extension plate is fixedly connected to a support plate, both sides of the upper end of the support plate are fixedly connected to a rotating seat, two bidirectional screws are rotatably connected inside the two rotating seats, both sides of the bidirectional screws pass through the rotating seats and are fixedly connected to driven gears, the upper end of one side of the support plate is fixedly connected to two second motors distributed in a mirror image, the output ends of the two second motors are fixedly connected to the driving gear, both sides of the outer wall of the bidirectional screw are threadedly connected to moving blocks, and the upper ends of the two moving blocks are fixedly connected to the fixed plate.

[0011] Through the above scheme, through the design of the bidirectional screw and the moving block, the relative movement between the two fixed plates can be achieved, so that the device can flexibly handle materials of different sizes or positions, increasing the flexibility and adaptability of the unloading process. The second motor drives the bidirectional screw to rotate through the engagement of the driving gear and the driven gear, thereby realizing the automatic movement of the moving block, reducing manual intervention, and improving the degree of automation of the production line.

[0013] Through the above solution, the introduction of the conveyor belt enables materials to be transferred efficiently and stably between the two slides. This design improves the efficiency of the unloading process and reduces stagnation and delays in the material transfer process. The sliding connection between the slide and the fixed plate, as well as the precise control of the connecting block by the electric slide, ensure that the slide and conveyor belt can be moved accurately to the required position.

[0015] Through the above solution, the sliding rod serves as a rigid structure connecting the two fixed seats, providing a stable guide for the movement of the fixed plate and the sliding plate, helping to reduce the shaking and deviation that may occur during the movement. The fixed connection between the fixed seat and the support plate, and the design of the sliding rod passing through the two fixed seats enhance the structural rigidity of the entire material transfer mechanism. This rigid structure can better resist external interference and vibration, ensuring the stability and reliability of the device during long-term operation.

[0016] Furthermore, the plurality of threaded rods are all threadedly arranged inside the threaded hole.

[0017] Through the above solution, the threaded connection between the threaded rod and the threaded hole is a firm and stable connection method, which can effectively resist loosening or displacement caused by vibration, impact or external force, thereby ensuring the stability of the device during operation.

[0018] Furthermore, the output ends of the plurality of first motors are fixedly connected to the threaded rod via couplings.

[0019] Through the above scheme, the coupling, as a device connecting two rotating parts, can directly and smoothly transmit the output power of the first motor to the threaded rod. This direct transmission method reduces energy loss and vibration during power transmission and improves the efficiency of power transmission.

[0020] Furthermore, the two driving gears are meshed with the driven gears.

[0021] According to the above solution, the motor drives the driving gear to rotate, and the driving gear and the driven gear are engaged, thereby driving the driven gear to rotate, thereby causing the bidirectional screw to rotate.

[0022] Compared with the existing technology, the technical solution of this application has the following beneficial effects:

The addition of magnets may be used to provide additional stability or fixing when the lifting plate is docked with the base or other docking components, thereby enhancing the overall stability and reliability of the device.

[0035] See also Figure 5 and Figure 6 The upper ends of the two second fixed plates 26 are slidably connected with a slide plate 27, and the upper ends of the two slide plates 27 are fixedly connected to a conveyor belt 28.

The sliding connection between the slide plate 27 and the second fixed plate 26, and the precise control of the connecting block 31 by the electric slide rail 29 ensure that the slide plate 27 and the conveyor belt 28 can be accurately moved to the required position.

[0036] See also Figure 1 、 Figure 5 and Figure 6 The upper end of one side of the support plate 19 is fixedly connected to two fixed seats 32 distributed in a mirror image. A sliding rod 33 is fixedly connected between the two fixed seats 32. A sliding sleeve 34 is slidably connected to the outside of the sliding rod 33.

[0037] In this embodiment, the unloading device of the placement machine realizes the automatic rotation and lifting of the discharge box 8 and the lifting plate 11 through the drive of the electric turntable 3 and the first motor 7. This automated design significantly improves production efficiency, reduces manual intervention, and reduces labor intensity. The discharge box 8 adopts a modular design, which is convenient for replacement and unloading. By adjusting the rotation direction and speed of the threaded rod 6, the lifting height of the lifting plate 11 can be accurately controlled to drive the lifting of the discharge box 8. Through the design of the swivel 2 and the electric turntable 3, multiple discharge boxes 8 can be unloaded in a limited space in turn, thereby improving space utilization. The addition of the magnet 15 may be used to provide additional stability or fixing when the lifting plate 11 is docked with the base 10 or other docking components, thereby enhancing the overall stability and reliability of the device.

[0038] It should be noted that when a discharge box 8 is being used, that is, the unloading operation is being carried out, another empty discharge box 8 is ready to be replaced inside the device. Once the current discharge box 8 is full or needs to be replaced, the full discharge box 8 can be quickly and smoothly moved to one side of the turntable through the rotation of the electric turntable 3. At the same time, the other empty or to-be-filled discharge box 8 is automatically moved to the unloading position.

[0039] The working principle of the above embodiment is:

[0040] Four discharge boxes 8 are placed on the turntable 4, and the bottom of each discharge box 8 is connected to the corresponding lifting plate 11. One discharge box 8 is in the discharge position so that the discharge box 8 can contact the material to be placed, and the other discharge boxes 8 are in a waiting state. When the discharge box 8 in the discharge position begins to receive materials and is gradually filled, the automation equipment continues to run, and the materials are accurately placed in the discharge box 8 through structures such as the conveyor belt 28. At the same time, another empty discharge box 8 has been rotated by the electric turntable 3, waiting to replace the current discharge box. Once the current discharge box 8 is full or reaches the replacement condition, the electric turntable 3 starts to rotate, and the full discharge box 8 is smoothly moved to one side of the turntable, away from the discharge position. At the same time, another empty discharge box 8 is automatically moved to the discharge position under the drive of the electric turntable 3. During the replacement process of box 8, the first motor 7 controls the lifting and lowering of the corresponding lifting plate 11 through the threaded connection of the threaded rod 6 and the threaded hole 13. The magnet 15 provides additional stability when the lifting plate 11 is docked with the base 10, thereby enhancing the overall stability of the device. The sliding connection between the slide 27 and the second fixed plate 26, and the precise control of the connecting block 31 by the electric slide rail 29 ensure that the conveyor belt 28 can be accurately moved to the required position to accommodate materials of different sizes or positions. When materials of different sizes or positions need to be processed, the second motor 23 drives the bidirectional screw 21 to rotate through the engagement of the driving gear 24 and the driven gear 22, thereby driving the moving block 25 and the second fixed plate 26 to move relative to each other. This design enables the device to flexibly adjust the position and spacing of the conveyor belt 28 to adapt to changes in production needs.
