Technical Field
[0001] This utility model relates to the field of circuit board feeding, specifically an anti-detachment component for a circuit board feeding structure. Background Technology
[0002] Circuit board feeding structure refers to a specialized automated equipment used in the process of circuit board manufacturing or component assembly to achieve precise, efficient, and stable transmission and positioning of circuit boards between different processes such as cutting, welding, testing, and assembly.
[0003] During the transport of irregularly shaped circuit boards by the transmission device, if traditional side-guided limiting devices such as parallel guide rails are used, the parallel guide rails rely on the circuit board having a standard straight edge or symmetrical contour to achieve effective lateral constraint and centering positioning. However, the edges of irregularly shaped circuit boards often have irregular contours, which makes it impossible for traditional guide devices to effectively fit with the edges of the circuit board. Since they only make contact at local points, they cannot form stable limiting support. During the transport process, the circuit board is very prone to lateral displacement or shaking and loses its center positioning. Utility Model Content
[0004] To overcome the shortcomings of existing technologies, when conveying irregularly shaped circuit boards, if traditional side-guided limiting devices such as parallel guide rails are used, the parallel guide rails rely on the standard straight edges or symmetrical contours of the circuit board to achieve effective lateral constraint and centering positioning. However, the edges of irregularly shaped circuit boards often have irregular contours, which makes it impossible for traditional guiding devices to effectively fit with the edges of the circuit board. Since there is only local point contact, it is impossible to form stable limiting support. The circuit board is prone to lateral displacement or shaking during the conveying process, and loses the problem of center positioning. This utility model proposes an anti-detachment component for the circuit board feeding structure.

[0016] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail. This application discloses an anti-detachment component for a circuit board feeding structure. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 An anti-detachment component for a circuit board feeding structure includes a workbench 1, a ring track conveying device 3 fixedly connected to the top of the workbench 1, a slider 4 slidably connected to the surface of the ring track conveying device 3, the number of sliders 4 being several, and an anti-detachment mechanism 2 being provided on the top of the slider 4. The anti-detachment mechanism 2 includes a tray 201, which is fixedly connected to the top of the slider 4. Two half-gears 202 are provided on one side of the tray 201. A rack 203 is provided on one side of each half-gear 202, with the surfaces of the racks meshing with the surfaces of the half-gears 202 respectively. Rotating columns 204 are rotatably connected to the tops of the two racks 203. Extension rods 205 are fixedly connected to the tops of both rotating columns 204. One end of each extension rod 205 penetrates the inner wall of the tray 201 and extends to the outside. A pressure plate 206 is fixedly connected to one end of each extension rod 205. A rubber pad 208 is fixedly connected to the bottom of each pressure plate 206. Arc-shaped grooves 2 are formed on the surfaces of both rotating columns 204. 07. The inner walls of the two arc-shaped chute 207 are equipped with positioning rods 209. By setting an anti-detachment mechanism 2, the rack 203 is driven to rise and fall by the half gear 202, which drives the rotating column 204, the extension rod 205 and the pressure plate 206 to move synchronously. When moving upward, the rotating column 204 is rotated by the positioning rod 209, so that the pressure plate 206 is turned away from the top of the tray 201, making it easier to put in the irregularly shaped circuit board. When moving downward, the rotating column 204 rotates in the opposite direction, driving the pressure plate 206 to rotate back to the top of the tray 201 and press down. The flexible rotation of the pressure plate 206 facilitates the picking and putting in of irregularly shaped circuit boards. During the pressing process, it automatically resets and locks, effectively preventing irregularly shaped circuit boards from falling off during transportation due to vibration, acceleration and deceleration or deviation, improving the stability and safety of the transmission process, and is suitable for various irregularly shaped board types to improve versatility.
[0017] Reference Figure 2 and Figure 3 The surface of the workbench 1 is provided with an annular groove 5. A mounting plate 6 is fixedly connected to one side of the tray 201. A pulley 11 is rotatably connected to one side of the mounting plate 6. The surface of the pulley 11 contacts the inner wall of the annular groove 5. One end of each of the two positioning rods 209 is fixedly connected to one side of the mounting plate 6. The two positioning rods 209 contact the inner walls of the two arc-shaped slides 207 through the mounting plate 6. Through the arrangement of the mounting plate 6, the annular groove 5 and the pulley 11, the mounting plate 6 can be supported and guided, so that the mounting plate 6 can move along the preset path and prevent the mounting plate 6 from deviating. Reference Figure 2A mounting plate 6 is fixedly connected to a mounting bracket 7 on one side. A dual-axis motor 8 is fixedly connected to the inner wall of the mounting bracket 7. The output ends of both sides of the dual-axis motor 8 pass through the inner wall of the mounting bracket 7. Through the mounting bracket 7 and the dual-axis motor 8, the mounting bracket 7 can fix the dual-axis motor 8 to ensure the stability of the dual-axis motor 8 during operation. The dual-axis motor 8 can provide driving force to the two half gears 202, so that the two half gears 202 can run synchronously and ensure that the two pressure plates 206 can move synchronously. Reference Figure 3 The output ends of the dual-axis motor 8 are fixedly connected to transmission rods 9. The two half gears 202 are rotatably connected to one end of the two transmission rods 9 respectively. Through the setting of the transmission rods 9, the power of the output ends of the dual-axis motor 8 can be transmitted to ensure that the actions of the two half gears 202 are completely consistent, and avoid the anti-detachment mechanism 2 from deviating due to asynchronous power transmission. Reference Figure 3 and Figure 4 Each of the two racks 203 has a dovetail block 12 fixedly connected to one side. The mounting plate 6 has a dovetail groove 10 on one side. There are two dovetail grooves 10. The surfaces of the two dovetail blocks 12 contact the inner walls of the two dovetail grooves 10 respectively. The racks 203 are slidably connected to one side of the mounting plate 6 through the dovetail blocks 12 and the dovetail grooves 10. The dovetail blocks 12 and the dovetail grooves 10 can guide the racks 203, prevent the racks 203 from shaking or getting stuck, and ensure that the racks 203 move in a straight line along a predetermined trajectory. Reference Figure 4 A spring 13 is provided between the top of the two rotating columns 204 and the bottom of the tray 201. One end of the spring 13 is fixedly connected to the top of the rotating column 204, and the other end of the spring 13 is fixedly connected to the bottom of the tray 201. With the setting of the spring 13, the spring 13 will store elastic potential energy after being compressed, and can automatically release energy after the external force is removed, providing driving force for the extension rod 205, the rotating column 204 and the rack 203. At the same time, the buffering effect of the spring 13 can reduce the impact force when the rotating column 204 rises.
[0018] Working principle: The circular track conveyor 3 drives the synchronous belt to rotate via a servo motor-driven synchronous pulley. The synchronous belt is connected to the slider 4 via a positioning device. The slider 4 is mounted on the circular guide rail. When the synchronous belt moves, it drives the slider 4 to circulate along the guide rail, realizing continuous material conveying between various workstations. This is existing technology and will not be elaborated further. When it is necessary to place irregularly shaped circuit boards in the tray 201, the user can start the dual-axis motor 8 through an external control switch. The dual-axis motor 8 is powered by an external power supply. The two output ends of the dual-axis motor 8 drive the transmission rod 9 to rotate. When the two transmission rods 9 are activated, they drive the connected half gear 202 to rotate. The surface of the half gear 202 meshes with the surface of the rack 203, thereby driving the rack 203 to move upward. The rack 203 moves within the dovetail groove 10 of the mounting plate 6 via the dovetail block 12. When the rack 203 moves upward, it drives the top rotating column 204 to move upward synchronously. During the upward movement of the rotating column 204, the positioning rod 209 is fixedly connected to the mounting plate 6. The arc-shaped sliding groove 207 on the rotating column 204 cooperates with the positioning rod 209. As the rotating column 204 moves upward, the arc-shaped sliding groove 207... 07 moves around the surface of the positioning rod 209, forcing the rotating column 204 to rotate around its own axis, thereby driving the extension rod 205 and the pressure plate 206 to rotate synchronously, so that the pressure plate 206 can rotate away from the tray 201, making it easier to put in the irregularly shaped circuit board. As the rotating column 204 moves upward, it will compress the spring 13 at the top. After the spring 13 is compressed, it will store elastic potential energy. After the irregularly shaped circuit board is put into the tray 201, the two output ends of the dual-axis motor 8 are controlled to rotate in opposite directions, driving the half gear 202 to rotate, driving the meshing rack 203 to move downward, under the rebound force of the spring 13 Under the combined action of gravity, the rotating column 204 moves down synchronously, and the arc-shaped groove 207 on the surface slides along the positioning rod 209 again, forcing the rotating column 204 to rotate in the opposite direction, driving the extension rod 205 and the pressure plate 206 to rotate and reset. The pressure plate 206 rotates back to above the tray 201 and presses down. By installing a rubber pad 208 at the bottom of the pressure plate 206, it can play a buffering and protective role during the pressing process of the pressure plate 206, avoiding scratches, indentations or damage to the surface of the circuit board caused by the pressure plate 206, thereby pressing and limiting the irregular circuit board and ensuring the safety and reliability of the conveying process.
