[0019] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0020] 1. The slider drives the horizontal bar to move upward, which in turn drives one end of the top rod connected to it to move upward. The other end of the top rod is hinged to the support plate, which causes the top rod to tilt upward and lift the PCB circuit board located inside the placement slot. The tilted top rod can lift multiple PCB circuit boards in an inclined position, which can separate multiple densely arranged PCB circuit boards vertically. By separating the PCB circuit boards vertically, the PCB circuit boards can be easily removed.

[0021] 2. By setting two sets of vertical placement slots, the two sets of placement slots work together to load a large number of PCB circuit boards, and can limit the PCB circuit boards to avoid damage caused by collision between adjacent PCB circuit boards during transportation. In addition, when the top rod pushes the PCB circuit board out, it can limit the PCB circuit board to prevent it from tilting or falling over during the rising process.

[0022] 3. By setting up a telescopic top rod, a movable block, and a connecting rope, the movable block can contact the telescopic top rod in the final stage when the PCB circuit board is about to be transported to the destination. Finally, as the lifting platform rises, the telescopic top rod presses down on the movable block, and the PCB circuit board is pushed out in the final stage, which can avoid unnecessary damage. Moreover, with the length adjustment feature of the telescopic top rod, different destination heights can be set to adapt to different working scenario requirements.

[0023] 4. By setting up a counterweight component, the connecting rope connects the counterweight component and the lifting platform. The counterweight component balances the load on the lifting platform, and then the motor drives the drive wheel to rotate, which in turn drives the connecting rope to lift the lifting platform. This reduces the power consumption of the motor, saves energy and is environmentally friendly, and contributes to achieving the goals of carbon peaking and carbon neutrality on schedule.

[0024] 5. By pulling out the connecting block placed inside the storage slot and then inserting the connecting block into the connecting slot between two adjacent counterweight blocks, different numbers of counterweight blocks can be connected so that the number of counterweight blocks connected to the drive rope is close to the load of the lifting platform. The number of counterweight blocks can be adjusted according to the load of the lifting platform. Attached Figure Description

[0050] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings. Example

[0051] This invention provides, for example Figure 1-6 The diagram shows a transfer lifting frame device for circuit board production, including a frame 01 and a lifting platform 02 disposed on one side of the frame 01 for transferring PCB circuit boards. A drive mechanism 03 for moving the lifting platform 02 up and down is provided between the lifting platform 02 and the frame 01. A storage mechanism 04 for placing PCB circuit boards is provided on the top of the lifting platform 02.

[0052] The lifting platform 02 is located on one side of the frame 01 and can slide up and down along the frame 01. The storage mechanism 04 located on the top of the lifting platform 02 is used to store PCB circuit boards. Finally, the driving mechanism 03 drives the lifting platform 02 to rise and fall, so that the PCB circuit boards placed inside the storage mechanism 04 slide up and down with the lifting platform 02, realizing the vertical transport of the PCB circuit boards.

[0053] The drive mechanism 03 is provided on one side of the frame 01 for balancing the lifting platform 02 and its load, and a drive rope 2 for connecting the counterweight assembly 1 and the lifting platform 02. The top of the frame 01 is equipped with a power assembly 3 for driving the lifting platform 02 by transmitting the drive rope 2.

[0054] The counterweight assembly 1 is connected to the lifting platform 02 via the drive rope 2. The counterweight assembly 1 and the lifting platform 02 are hung on both sides of the power assembly 3 via the drive rope 2. The weight of the counterweight assembly 1 is used to balance the load of the lifting platform 02. When the power assembly 3 drives the drive rope 2 to lift the lifting platform 02, it does not need to overcome the gravity of the lifting platform 02 and its load. It only needs to overcome the resistance during lifting, thereby reducing the energy consumption of the lifting frame in vertically transporting PCB circuit boards, so as to achieve the effect of energy saving and emission reduction.

[0055] The storage mechanism 04 includes a placement box 4 placed on top of the lifting platform 02 for storing PCB circuit boards. The bottom of the placement box 4 has a through groove 5. Inside the through groove 5, there is a push rod 6 for pushing the PCB circuit boards inside the placement box 4 upward. One end of the push rod 6 is provided with a lifting component 7 for driving the push rod 6 to move.

[0056] The placement box 4 is placed on top of the lifting platform 02 to store the PCB circuit boards that need to be transferred. The through slot 5 at the bottom of the placement box 4 cooperates with the push rod 6 inside it. The push rod 6 can be moved upward to push the PCB circuit boards inside the placement box 4 out of the placement box 4, making it easy to access the PCB circuit boards inside the placement box 4.

[0057] The frame 01 includes a base plate 011, a top plate 012 is arranged parallel to the top of the base plate 011, and two parallel support columns 013 are arranged between the top plate 012 and the bottom. The two ends of the support columns 013 are connected to the top plate 012 and the bottom respectively. A guide rod 014 is arranged on one side of each of the two support columns 013. The guide rod 014 is arranged parallel to the support column 013, and the two ends of the guide rod 014 are connected to the top plate 012 and the base plate 011 respectively.

[0058] The top plate 012 and the bottom plate 011 are fixed to the top and bottom of the two support columns 013, respectively. The guide rod 014 is set parallel to the support column 013 and its two ends are fixed to the top plate 012 and the bottom plate 011, respectively. It can cooperate with the support column 013 to form the lifting track of the lifting platform 02, which can limit the lifting platform 02. Furthermore, the bottom plate 011 and the top plate 012 are connected by the two support columns 013 and the two guide rods 014, which can improve the connection effect between the bottom plate 011 and the top plate 012, thereby improving the structural strength of the frame 01.

[0059] The lifting platform 02 includes a movable frame 021 located on one side of the guide rod 014. The top of the movable frame 021 is connected to one end of the drive rope 2. A support plate 022 is installed on one side of the movable frame 021. Two sets of guide wheels 023 adapted to the guide rod 014 are installed on the other side of the movable frame 021. A support wheel 024 adapted to the support column 013 is provided on one side of the guide wheel 023. The support wheel 024 and the guide wheel 023 are arranged between the guide rod 014 and the support column 013. The support wheel 024 is connected to the movable frame 021 through a fixed frame 025 installed on both sides of the movable frame 021.

[0060] The support plate 022 is connected to the movable frame 021. The movable frame 021 is used to connect the frame 01 and guide the lifting platform 02. The support plate 022 is used to support the placement box 4. Through two sets of guide wheels 023 installed on one side of the movable frame 01, they can be adapted to the guide rod 014. In addition, in conjunction with the support wheel 024, the guide wheel 023 and the support wheel 024 are restricted on the lifting track of the support column 013 and the guide rod 014, thus limiting the overall position of the lifting platform 02.

[0061] The specific implementation method is as follows: In use, the PCB circuit board is first vertically inserted into the placement box 4, and then the placement box 4 is placed on the support plate 022 on the lifting platform 02, so that the top rod 6 of the lifting platform 02 is placed into the through groove 5. The power component 3 drives the drive rope 2, which drives the lifting platform 02 connected to it to lift the PCB circuit board on top of it upward. The guide wheel 023 and the support wheel 024 are restricted by the support column 013 and the guide rod 014 to prevent the lifting platform 02 from tilting during the lifting process. By setting the counterweight component 1 at the other end of the drive rope 2, the load of the lifting platform 02 is balanced and the power consumption of the power component 3 is reduced. After reaching the designated position, the top rod 6 is lifted by the lifting component 7, so that the top rod 6 pushes out the PCB circuit board inside the placement box 4. Example

[0062] Based on the counterweight component 1 and power component 3 proposed in Embodiment 1, the present invention provides, as follows: Figure 7-10 Further technical solutions.

[0063] The counterweight assembly 1 includes multiple long, stacked counterweight blocks 11. The end of the drive rope 2 away from the movable frame 021 is connected to the topmost counterweight block 11. The counterweight block 11 is positioned between two support columns 013 and is slidably connected to the support columns 013. A guide rail 12 adapted to the counterweight block 11 is installed on the side of the support column 013 near the counterweight block 11. A connecting block 13 with an hourglass-shaped cross-section is provided between adjacent counterweight blocks 11. A connecting groove 14 adapted to the connecting block 13 is provided on the side of the counterweight block 11 near the connecting block 13. The connecting block 13 is slidably connected to the connecting groove 14. A storage groove 15 for placing the connecting block 13 is provided on one side of the counterweight block 11 and is adapted to the connecting block 13.

[0064] The number of counterweights 11 is set to multiple, and the number of counterweights 11 can be adjusted according to the weight of the load so that the weight of the counterweight assembly 1 is close to the load of the lifting platform 02. This allows the lifting platform 02 to move vertically with less power output. The guide rail 12 is installed on the side of the support column 013 near the counterweights 11, which can limit the counterweights 11 located between the two support columns 013 and prevent the counterweights 11 from falling out of the space between the two support columns 013. When using the counterweight assembly 1, the connecting grooves 14 between adjacent counterweights 11 cooperate. The connecting block 13 with an hourglass-shaped cross section is inserted into the connecting groove 14 to connect two adjacent counterweights 11 together. Through the cooperation of the connecting block 13 and the connecting groove 14, different numbers of counterweights 11 can be connected as needed. Moreover, for counterweights 11 that do not need to be connected, the connecting block 13 can be placed in the storage groove 15.

[0065] The power assembly 3 includes a drive wheel 31 mounted on the top of the top plate 012. The top of the top plate 012 has a groove 32 corresponding to the drive wheel 31. The drive rope 2 passes through the groove 32 and is sleeved on the outside of the drive wheel 31. The drive rope 2 is adapted to the drive wheel 31. Limiting wheels 33 are provided on both sides of the drive wheel 31. The limiting wheels 33 are mounted on the top of the top plate 012 and are adapted to the drive rope 2. The drive rope 2 is arranged between the limiting wheels 33 and the drive wheel 31. A motor 34 is mounted on the top of the top plate 012. The output shaft of the motor 34 is connected to the rotating shaft of the drive wheel 31.

[0066] The two ends of the drive rope 2 are connected to the counterweight block 11 at the top of the counterweight assembly 1 and the movable frame 021 on the movable platform 02, respectively. The middle part of the drive rope 2 is hung on the drive wheel 31 and is adapted to the drive wheel 31. The rotation of the drive wheel 31 can drive the drive rope 2 to pull the movable platform 02 up and down. Two limit wheels 33 are set on both sides of the drive wheel 31. By setting the limit wheels 33, the drive rope 2 is directed towards the drive wheel 31, which increases the contact area between the drive rope 2 and the drive wheel 31 and prevents slippage between the drive rope 2 and the drive wheel 31. The counterweight block 11 can balance the load of the movable platform 02 and reduce the resistance to drive the movable platform 02, further preventing slippage between the drive rope 2 and the drive wheel 31. The output shaft of the motor 34 is connected to the rotating shaft of the drive wheel 31. The output shaft of the motor 34 can drive the drive wheel 31 to raise and lower the movable platform 02.

[0067] The specific implementation method is as follows: After the placement box 4 is placed on the lifting platform 02, the weight of the counterweight component 1 is adjusted. The connecting block 13 placed inside the storage slot 15 is pulled out, and then the connecting block 13 is inserted into the connecting slot 14 between two adjacent counterweight blocks 11. Different numbers of counterweight blocks 11 can be connected so that the number of counterweight blocks 11 connected to the drive rope 2 is close to the load of the lifting platform 02. Then the motor 34 is started. The output shaft of the motor 34 drives the shaft of the drive wheel 31 to rotate, so that the drive wheel 31 drives the drive rope 2 that is adapted to it, thereby driving the movable platform 2 connected to the drive rope 2 to rise and fall. Example

[0068] Based on the placement box 4 and lifting assembly 7 proposed in Embodiment 1, the present invention provides as follows: Figure 11-15 Further technical solutions.

[0069] The placement box 4 is placed on top of the support plate 022. Two sets of placement slots 8 for PCB circuit boards are opened on both sides of the inner wall of the placement box 4. The placement slots 8 are perpendicular to the through slots 5. The through slots 5 have a U-shaped cross-section and extend to both sides of the placement box 4. The end of the top rod 6 away from the lifting component 7 is hinged to the support plate 022. A baffle 9 for positioning the placement box 4 is arranged parallel to one side of the top rod 6.

[0070] Two sets of placement slots 8 are respectively opened on both sides of the inner wall of the placement box 4. Through the two sets of corresponding placement slots 8, PCB circuit boards can be inserted into them and the PCB circuit boards placed therein are limited to prevent adjacent PCB circuit boards from bumping into each other. The through slot 5 passes through the placement box 4 and is set perpendicular to the placement slot 5. The top rod 6 is set inside the through slot 5, and one end of the top rod 6 is hinged to the support plate 022. The height of one end of the top rod 6 can be raised by the lifting component 7 located at the other end of the top rod 6, so that the top rod 6 tilts upward and lifts the PCB circuit board located inside the placement slot 8. The tilted top rod 6 can lift multiple PCB circuit boards in an inclined position, so that multiple densely arranged PCB circuit boards can be separated vertically, thereby facilitating the removal of the PCB circuit boards.

[0071] The baffle 9 is installed on the top of the support plate 022, and the cross-sectional shape of the baffle 9 is set to L-shape;

[0072] The baffle 9 is installed on the top of the support plate 022. Its L-shaped shape can position one corner of the placement box 4, thereby positioning the placement box 4.

[0073] Furthermore, the placement box 4 can be set to various specifications to adapt to different models of PCB circuit boards. Simply open the through slot 5 in the corresponding position to adapt to different specifications of PCB circuit boards.

[0074] The lifting assembly 7 includes a slide 71 fixed to the top of the support plate 022. A slider 72 is provided inside the slide 71. The slider 72 is slidably connected to the slide 71. A crossbar 73 passes through the slider 72. The crossbar 73 is slidably connected to the slider 72. One end of the crossbar 73 is hinged to one end of the top rod 6.

[0075] The slide 71 is installed on the top of the support plate 022 on one side of the placement box 4. The crossbar 73 passes through the slider 72 inside the slide 71, so that the crossbar 73 can slide left and right as the slider 72 rises and falls. One end of the crossbar 73 is hinged to one end of the top rod 6. When the slider 72 rises, it drives the crossbar 73 to rise, which can drive the top rod 6 hinged to it to rise. Furthermore, the crossbar 73 can slide as the top rod 6 rises, so as not to obstruct the rise of the top rod 6.

[0076] The slider 72 has a cross-shaped cross section and is adapted to the inner wall of the slide 71. The top of the slide 71 is provided with a drive assembly 74 for driving the slider 72.

[0077] The cross-shaped slider 72 can be effectively limited inside the carriage 71 to prevent it from extending outside the carriage 71. The movement of the slider 72 can be limited, while the drive assembly 74 at the top of the carriage 71 can drive the slider 72 to slide upward along the carriage.

[0078] The drive assembly 74 includes a slide groove 741 formed on one side of the slide 71. A movable block 742 adapted to the slide groove 741 is provided inside the slide groove 741. A guide wheel 743 is installed on the top of the slide 71. A connecting rope 744 adapted to the guide wheel 743 is provided on the top of the guide wheel 743. The two ends of the connecting rope 744 are respectively connected to the movable block 742 and the slider 72.

[0079] The movable block 742 cooperates with the slide groove 741 to move up and down along the slide groove 741 on one side of the slide 71. With the cooperation of the guide wheel 743 and the connecting rope 744, when the movable block 742 descends, the connecting rope 744 can drive the slider 72 to move upward, which can drive the top rod 6 to rise, thereby realizing the separation of the PCB circuit board.

[0080] The top plate 012 is provided with a connecting plate 745 corresponding to the slide 71. The connecting plate 745 is connected to the top plate 012. A telescopic top rod 746 is vertically inserted through the bottom of the connecting plate 745. The telescopic top rod 746 is fixedly connected to the connecting plate 745. The bottom end of the telescopic top rod 746 corresponds to the movable block 742.

[0081] One end of the telescopic top rod 746 is fixed to the top plate 012 via the connecting plate 745, and the other end corresponds to the movable block 742. As the lifting platform 02 rises, it can drive the slide 71 to move upward, causing it to drive the movable block 742 to rise and contact one end of the telescopic top rod 746. Then, the telescopic top rod 746 abuts against the top of the movable block 742. As the lifting platform 02 rises, the telescopic top rod 746 pushes the movable block 742 downward, thereby driving the slider 72 to move upward via the connecting rope 744. Furthermore, by setting the telescopic top rod 746, the contact position between the telescopic top rod 746 and the movable block 742 can be set.

[0082] The specific implementation method is as follows: In use, the length of the telescopic top rod 746 can be set according to the required lifting height of the PCB circuit board. Then, the drive mechanism 03 drives the lifting platform 02 to rise, which in turn drives the movable block 742 on one side of the slide 71 to rise, so that it contacts one end of the telescopic top rod 746. Then, the telescopic top rod 746 abuts against the top of the movable block 742, causing the telescopic top rod 746 to push the movable block 742 downward. Then, the connecting rope 744 drives the slider 72 to move upward, which in turn drives one end of the top rod 6 through the crossbar 73, causing the top rod 6 to tilt, raising multiple PCB circuit boards inside the placement box 4 in sequence, so that adjacent PCB circuit boards can be staggered, thereby making it convenient for operators to remove the PCB circuit boards.

[0083] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
