Description

Technical Field

[0001] This utility model relates to a board loading machine, and more particularly to a board loading machine for an STM production line. Background Technology

[0002] In surface mount technology (SMT) production lines, the board loading machine is a key piece of equipment used to automatically or semi-automatically feed printed circuit boards (PCBs) into the production line. The main function of the board loading machine is to remove the PCB from its storage location or tray before production begins and accurately transport it to the starting position of the production line for subsequent processes such as solder paste printing and component placement.

[0003] Traditional board loading machines are typically manual or semi-automatic. Manual machines require operators to load and correct the position, resulting in low production efficiency and a high risk of errors. Semi-automatic machines, which combine manual and automatic operation, are more efficient than manual machines, but still require human intervention. Operators place the PCBs into the designated positions on the machine, and the machine automatically completes the alignment and conveying process. This limits its application in fully automated production lines. Furthermore, to achieve the alignment and loading functions, semi-automatic board loading machines usually require the addition of complex sensing structures, which not only increases production costs but also makes daily maintenance and troubleshooting inconvenient. Utility Model Content

[0004] To overcome the aforementioned shortcomings, the technical problem is to provide a board loading machine for an STM production line.

[0005] The technical solution is as follows: A loading machine for an STM production line includes a bracket, a storage frame, a support plate, a receiving plate, a first connecting rod, a clamping plate, a second connecting rod, a conveying assembly, and auxiliary components. The storage frame is connected to the upper right side of the bracket, and the support plate is symmetrically connected to the lower part of the storage frame. The first connecting rod is slidably connected to the lower side of the support plate, and the receiving plate is connected to the inner side of the first connecting rod. The second connecting rod is slidably connected to the upper side of the support plate, and the clamping plate is connected to the inner side of the second connecting rod. The conveying assembly is provided on the bracket, and the auxiliary components are provided on the support plate.

[0006] Furthermore, the circuit boards are stacked in the storage frame and supported by the receiving plate.

[0007] Furthermore, the thickness of the receiving plate and the clamping plate is the same as the thickness of the circuit board. The receiving plate is located below the clamping plate, and the clamping plate is aligned with the second circuit board from the bottom up. The receiving plate supports all the circuit boards.

[0008] Furthermore, the conveying assembly includes a stepper motor, a drive roller, a conveyor belt, push plates, and top blocks. A stepper motor is installed on the right side of the front of the support. Drive rollers are symmetrically and rotatably connected to the upper side of the support. A conveyor belt is wound between the drive rollers. The output shaft of the stepper motor is connected to the drive roller on the right side. Four push plates are connected at intervals on the conveyor belt. Top blocks are connected to both sides of the conveyor belt near the sides of each push plate.

[0009] Furthermore, the auxiliary components include a first triangular block, a first spring, a second triangular block, and a second spring. The first triangular block is connected to the outer side of the first connecting rod. The first spring is connected between the receiving plate and the support plate on the same side. The first spring is sleeved on the first connecting rod. The second triangular block is connected to the outer side of the second connecting rod. The second spring is connected between the clamping plate and the support plate on the same side. The second spring is sleeved on the second connecting rod.

[0010] Furthermore, the inclined surfaces of the first triangular block and the second triangular block are arranged opposite each other, and the top block moves with the conveyor belt and contacts and engages with the inclined surfaces of the first triangular block and the second triangular block.

[0011] The beneficial effects of this utility model are as follows: through the cooperation of the top block, the first triangular block and the second triangular block, the movement of the receiving plate and the clamping plate can be flexibly controlled, ensuring that only one circuit board is fed at a time, so that the circuit boards stacked in the storage box can be automatically fed, reducing the dependence on operators, reducing the time and labor costs of manual operation, and improving production efficiency.

Detailed Implementation

[0017] The present invention will be further described below with reference to specific embodiments. It should also be noted that, unless otherwise explicitly specified and limited, terms such as "setting," "installing," "connecting," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention based on the specific circumstances.

[0018] Example: A board loading machine for an STM production line, such as Figures 1-4 As shown, the assembly includes a bracket 1, a storage frame 6, a support plate 8, a receiving plate 9, a first connecting rod 10, a clamping plate 13, a second connecting rod 14, a conveying assembly, and auxiliary components. The storage frame 6 is connected to the upper right side of the bracket 1. Circuit boards 7 are stacked inside the storage frame 6 and supported by the receiving plate 9. The support plate 8 is symmetrically welded to the lower part of the storage frame 6. The first connecting rod 10 is slidably connected to the lower side of the support plate 8. The receiving plate 9 is welded to the inner side of the first connecting rod 10. The second connecting rod 14 is slidably connected to the upper side of the support plate 8. The clamping plate 13 for clamping the circuit boards 7 is welded to the inner side of the second connecting rod 14. The thickness of the receiving plate 9 and the clamping plate 13 is the same as the thickness of the circuit boards 7. The receiving plate 9 is located below the clamping plate 13. The clamping plate 13 is aligned with the second circuit board 7 from the bottom up. The receiving plate 9 supports all the circuit boards 7. The bracket 1 is equipped with a conveying assembly, and the support plate 8 is equipped with auxiliary components.

[0019] like Figures 1-2 As shown, the conveying assembly includes a stepper motor 2, a drive roller 3, a conveyor belt 4, a pusher plate 5, and a top block 17. The stepper motor 2 is bolted to the front right side of the bracket 1. The drive roller 3 is symmetrically rotated on the upper side of the bracket 1. The conveyor belt 4 for conveying the circuit board 7 is wound between the drive rollers 3. The output shaft of the stepper motor 2 is connected to the drive roller 3 on the right side. Four pusher plates 5 are connected at intervals on the conveyor belt 4. The top block 17 is connected to the front and rear sides of the conveyor belt 4 near the front and rear sides of each pusher plate 5.

[0020] like Figures 3-4As shown, the auxiliary components include a first triangular block 11, a first spring 12, a second triangular block 15, and a second spring 16. The first triangular block 11 is welded to the outer side of the first connecting rod 10. The first spring 12 is connected between the receiving plate 9 and the support plate 8 on the same side. The first spring 12 is sleeved on the first connecting rod 10. The second triangular block 15 is welded to the outer side of the second connecting rod 14. The second spring 16 is connected between the clamping plate 13 and the support plate 8 on the same side. The second spring 16 is sleeved on the second connecting rod 14. The inclined surfaces of the first triangular block 11 and the second triangular block 15 are arranged opposite each other, and the inclined surfaces of the two form a V-shaped structure. The top block 17 moves with the conveyor belt 4 and contacts and engages with the inclined surfaces of the first triangular block 11 and the second triangular block 15. The length of the right end inclined surface of the second triangular block 15 is longer than the length of the inclined surface of the first triangular block 11. The top block 17 will contact the second triangular block 15 first.

[0021] When processing circuit board 7, this device can accurately feed circuit board 7 into the SMT production line. The device is installed next to the production line, and circuit board 7 is stacked in storage frame 6, supported by receiving plate 9. Stepper motor 2 is started, and the output shaft of stepper motor 2 rotates, driving conveyor belt 4 through two transmission rollers 3. Conveyor belt 4 drives push plate 5 and top block 17 to move. When top block 17 moves to contact the second triangular block 15, it pushes the second triangular block 15 inward, stretching the second spring 16. The second triangular block 15 drives the second connecting rod 14 and clamping plate 13 inward, clamping the second circuit board 7 from bottom to top in storage frame 6. Immediately afterwards, top block 17 contacts the inclined surface of the first triangular block 11, pushing the first triangular block 11 outward. The first spring 12 is compressed, and the first connecting rod 10 and receiving plate 9 move outward as well. The conveyor belt 4, pusher plate 5, and top block 17 move, causing the receiving plate 9 to stop supporting the circuit board 7. The bottom circuit board 7 then falls onto the conveyor belt 4. The conveyor belt 4, pusher plate 5, and top block 17 continue to move. Pusher plate 5 pushes the circuit board 7 on the conveyor belt 4 to the left, while top block 17 continues to move and disengages from the first triangular block 11 and the second triangular block 15. The first spring 12 and the second spring 16 rebound and reset, causing the first connecting rod 10 and the receiving plate 9 to move inward and reset. The clamping plate 13 and the second connecting rod 14 move outward and reset, thereby loosening the clamp on the circuit board 7. The remaining circuit boards 7 in the storage box 6 then fall onto the receiving plate 9. In this way, the automatic feeding of one circuit board 7 is completed. The conveyor belt 4 continues to rotate, driving pusher plate 5 and top block 17 to move continuously. The above operation will be used to continuously feed the circuit boards 7 without manual intervention. Only adding circuit boards 7 to the storage box 6 is required.

However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
