[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] First embodiment

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 ,in, Figure 1 A schematic structural diagram of a first embodiment of a PCB feeding mechanism of a drop-type PCB feeding machine provided by the present invention; Figure 2 for Figure 1 A schematic structural diagram of a side section of the base shown; Figure 3 for Figure 1 A schematic diagram of the structure of the top of the base shown; Figure 4 for Figure 2The enlarged schematic diagram of part A is shown. A PCB feeding mechanism of a drop-type PCB feeding machine comprises: a base 1;

[0034] A communication port 2 is provided inside the base 1. A threaded rod 3 is provided inside the communication port 2. A threaded block 4 is sleeved on the surface of the threaded rod 3. A rotating shaft 6 is rotatably connected to the top of the threaded block 4. A gear 7 is fixedly mounted on the surface of the rotating shaft 6. A fixed disk 8 is fixedly mounted on the top of the rotating shaft 6. A motor 5 is fixedly mounted on the right side of the base 1 and on the right side of the threaded rod 3.

[0035] The overall structure performs a falling-type board delivery operation during the board delivery operation, and the overall device is located in one part.

[0036] A fixing groove 13 is provided on the left side of the base 1. A locking bolt 14 is provided inside the fixing groove 13. A nut 15 is sleeved on the surface of the locking bolt 14. One end of the inner side of the locking bolt 14 is located inside the communication port 2 and is rotatably connected to a toothed plate 16.

[0037] The mutual cooperation between the locking bolt 14, the nut 15 and the fixing groove 13 can facilitate the adjustment of the use position of the tooth plate 16, thereby controlling the rotation position of the gear 7, so that it can be adjusted to the required position before rotating to the required position.

[0038] A locking structure is fixedly installed on the outer side of the threaded block 4.

[0039] The locking structure includes a mounting frame 17, a slip ring 18 is slidably connected to the surface of the mounting frame 17, a spring 19 is provided at the bottom of the slip ring 18 and located on the surface of the mounting frame 17, and a friction ring 20 is fixedly installed on the outside of the slip ring 18 via a folding rod.

[0040] The elastic deformation of the spring 19 causes the slip ring 18 to be always forced upward, so that the friction ring 20 is always forced upward, so that the friction ring 20 is in close contact with the bottom of the gear 7, so that the gear 7 will not rotate randomly when it is not engaged with the tooth plate 16, thereby improving its working stability.

[0041] A docking groove 9 is provided inside the fixing plate 8 , and a docking post 10 is provided inside the docking groove 9 .

[0042] A fixing plate 12 is fixedly installed on the top of the docking column 10 , and a first telescopic rod 11 is fixedly installed on the right side inside the fixing plate 8 and on the right side of the docking column 10 .

[0043] The fixed plate can be pushed outwards to move by the mutual cooperation between the docking groove, the docking column and the first telescopic rod, so that the plate is sent when it is not on the top of the fixed plate.

[0044] The working principle of the PCB feeding mechanism of the drop-down PCB feeding machine provided by the present invention is as follows:

[0045] Its PCB board is placed on the fixed plate 12, and then the motor 5 can be started, and the rotation of the motor 5 drives the threaded rod 3 to rotate, and the rotation of the threaded rod 3 causes the threaded block 4 sleeved on its surface to move laterally, and the movement of the threaded block 4 drives all structures installed on the threaded block 4 to move to the right, and at the same time its gear 7 moves. When its gear 7 moves to a state of engagement with the tooth plate 16, and because the tooth plate 16 is stationary and the gear moves to the right, there will be a situation where the gear 7 rotates, and the rotation of the gear 7 drives the rotating shaft 6 to rotate, and the rotation of the rotating shaft 6 drives the fixed plate 8 to rotate, and the rotation of the fixed plate 8 drives the docking groove 9, the docking column 10 and the first telescopic rod 11 and the fixed plate 12 to rotate, until the tooth plate 16 and the gear 7 are disengaged. At this time, the outer opening position of the docking groove 9 is rotated to a suitable and required direction, or when it rotates to a suitable angle during rotation, the rotation of the motor 5 can be stopped.

[0046] Then, the first telescopic rod 11 can be activated to extend and push the docking column 10 outward, so that the docking column 10 moves outward in the docking groove 9, and at the same time, the fixed plate 12 is driven to move until it is sent to a suitable position. The rightward movement of the threaded block 4 drives the fixed plate 12 to move to the right to send the plate, and the fixed plate 12 is also extended in other directions and is at the top of the fixed disk 8 when it is sent.

[0047] Compared with the related art, the feeding mechanism of the PCB drop-type feeding machine provided by the present invention has the following beneficial effects:

[0048] Through the mutual cooperation among the structures such as the base 1, the connecting port 2, the threaded rod 3, the threaded block 4, the motor 5, the rotating shaft 6, the gear 7, the fixed plate 8, the fixing groove 13, the locking bolt 14, the nut 15, and the tooth plate 16, the convenience of sending the plate can be changed according to the actual situation during the sending process, thereby improving the performance of the overall structure.

[0049] Second embodiment

[0050] Please refer to Figure 5 and Figure 6Based on the first embodiment of this application, which provides a PCB board feeding mechanism for a drop-down PCB feeder, the second embodiment of this application provides another PCB board feeding mechanism for a drop-down PCB feeder. The second embodiment is merely a preferred embodiment of the first embodiment, and implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0051] Specifically, the second embodiment of the present application provides a PCB board drop-type board feeder with a board feeding mechanism that is different in that, in a PCB board drop-type board feeder, both sides of the front of the fixed plate 12 are provided with a slide groove 21, and both sides of the slide groove 21 are slidably connected with a slider 22.

[0052] A communication groove 23 is defined inside the fixing plate 12 and located inside the sliding groove 21 .

[0053] A biaxial telescopic rod 24 is fixedly mounted on the inner side of the communicating groove 23 , and a mounting post 25 is fixedly mounted on the output end of the biaxial telescopic rod.

[0054] The cooperation between the slider 22 and the slide groove 21 can improve the stability of the lateral movement of the mounting column 25 and the connecting rod 26.

[0055] The outer side of the mounting post 25 is fixedly mounted to the inner side of the slider 22 , and the top of the slider 22 is rotatably connected to a connecting rod 26 .

[0056] The top of the connecting rod 26 is rotatably connected to a lifting plate 29 , and limiting holes 27 are provided on both sides of the inner side of the lifting plate 29 .

[0057] A limiting rod 28 is provided inside the limiting hole 27 , and the bottom of the limiting rod 28 is fixedly mounted to the top of the fixing plate 12 .

[0058] The cooperation between the limiting rod 28 and the limiting hole 27 can improve the stability of the longitudinal movement of the lifting plate 29, thereby preventing it from shaking left and right during movement or operation.

[0059] The working principle of the PCB feeding mechanism of the drop-down PCB feeding machine provided by the present invention is as follows:

[0060] When the height of the feeding plate needs to be changed, the biaxial telescopic rod 24 can be activated, and the retraction of the biaxial telescopic rod 24 drives the mounting post 25 to move, and the movement of the mounting post 25 drives the slider 22, causing the slider 22 to slide inside the slide groove 21, and the sliders 22 slidably connected to both sides of the slide groove 21 slide from the outside to the inside in opposite directions.

[0061] The movement of the slider 22 drives the connecting rod 26 to move, and then the lifting plate 29 can be pushed upward by the angle change caused by the movement of the connecting rod 26. Then, the position height of the PCB board placed on the lifting plate 29 can be changed by the upward movement of the lifting plate 29.

[0062] When the lifting plate 29 moves upward, the limiting hole 27 is driven to move upward, and the limiting hole 27 moves on the surface of the limiting rod 28 .

[0063] Compared with the related art, the feeding mechanism of the PCB drop-type feeding machine provided by the present invention has the following beneficial effects:

[0064] Through the mutual cooperation among the structures such as the slide groove 21, the slider 22, the connecting groove 23, the biaxial telescopic rod 24, the mounting column 25, the connecting rod 26, the limiting hole 27, the limiting rod 28, and the lifting plate 29, the height of the plate when being sent can be changed, thereby facilitating the subsequent processing work.

[0065] Third embodiment

[0066] Please refer to Figure 7 Based on the first embodiment of this application, which provides a PCB board feeding mechanism for a drop-down PCB feeder, the third embodiment of this application provides another PCB board feeding mechanism for a drop-down PCB feeder. The third embodiment is merely a preferred embodiment of the first embodiment, and implementation of the third embodiment will not affect the independent implementation of the first embodiment.

[0067] Specifically, the difference of the feeding mechanism of a PCB board drop-type board feeder provided in the third embodiment of the present application is that, in a feeding mechanism of a PCB board drop-type board feeder, both sides of the bottom of the fixed plate 12 are fixedly installed with plug-in columns 31, and the bottom of the plug-in columns 31 is fixedly installed with a first magnetic ring 32.

[0068] A connecting frame 33 is provided at the bottom of the fixing plate 12 . Insertion holes 34 are provided on both sides of the inner side of the connecting frame 33 . A second magnetic ring 35 is fixedly installed at the bottom of the inner side of the insertion hole 34 .

[0069] When the first magnetic ring 32 and the second magnetic ring 35 are in contact, they can restrict the position of the plug-in pin 31 , so that the plug-in pin 31 can be stably inserted into the connecting frame 33 .

[0070] The working principle of the PCB feeding mechanism of the drop-down PCB feeding machine provided by the present invention is as follows:

[0071] When the fixing plate 12 needs to be removed, the fixing plate 12 can be manually pulled upward, and the upward movement of the fixing plate 12 drives the pin 31 to be forced upward, and then the upward force of the pin 31 drives the first magnetic ring 32 to be forced until the first magnetic ring 32 and the second magnetic ring 35 are separated. Therefore, the pin 31 loses its fixed position state, and the pin 31 can be detached and inserted into its socket 34, thereby completing the disassembly of the fixing plate 12.

[0072] Compared with the related art, the feeding mechanism of the PCB drop-type feeding machine provided by the present invention has the following beneficial effects:

[0073] Through the mutual cooperation between the structures such as the plug post 31, the first magnetic ring 32, the connecting frame 33, the jack 34, and the second magnetic ring 35, it is convenient to disassemble and install the fixed plate 12, and replace the fixed plate 12 corresponding to the shape and size of the PCB board in turn to deliver the board, thereby improving the stability of its board delivery.
