Description

Technical Field

[0001] This utility model relates to the field of circuit board transfer technology, specifically a rapid loading device for circuit boards. Background Technology

[0002] Circuit boards are a technology that miniaturizes and visualizes circuits. They are typically used in products to optimize the layout of internal electrical components. They are characterized by high reliability, high wiring density, light weight, and thinness, and have wide applications in various fields. The production and processing of circuit boards requires multiple steps. During the processing, when transporting circuit boards to the next processing workshop, the tightly arranged circuits on the circuit boards are easily damaged, so circuit board transfer devices are needed for transportation.

[0003] Publication No. CN222591533U discloses a circuit board transfer device. This device, consisting of a movable base, frame, and support components made of aluminum alloy, allows the frame to be movably mounted on the movable base. The frame can be quickly fixed and released via the extension and retraction of locking components, meeting the needs of different operating scenarios. The first and second locking positions have multiple locking slots, enabling quick adjustment of various circuit boards. However, this patent still has the following problems in practical use: The device, consisting of a movable base, frame, and support components made of aluminum alloy, allows for the frame to be movably mounted on the movable base. The frame can be quickly fixed and released via the extension and retraction of locking components, meeting the needs of different work scenarios. The first and second locking positions have multiple locking slots, enabling quick adjustment to accommodate various circuit boards. While circuit board production lines typically use conveyor equipment for transporting and processing circuit boards, this device lacks a rapid board loading function. This forces workers to frequently bend over to transfer circuit boards from the conveyor belt to the transport vehicle, significantly reducing production efficiency and causing inconvenience for operators.

[0004] A rapid loading device for circuit boards is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this utility model is to provide a rapid loading device for circuit boards, in order to solve the problems mentioned in the background art. Currently, the device uses a movable seat, frame, and support components made of aluminum alloy. The frame can be movably installed on the movable seat. The frame can be quickly fixed and released by the extension and retraction control of the locking parts, meeting the needs of different working scenarios. The first and second locking positions are equipped with multiple locking positions, which can adapt to various different circuit boards for rapid adjustment. Since circuit boards are generally transported and processed by conveyor equipment on the circuit board production line, but this device does not have the function of rapid loading of circuit boards, workers need to frequently bend over to transfer circuit boards from the conveyor belt to the transfer vehicle, which greatly reduces the efficiency of circuit board production.

The inside of each collecting frame is fixedly installed with a partition, and rubber pads are fixedly installed on both sides of the partition and the inside of the collecting frame. A handle is fixedly connected to one side of the front of the collecting frame, and a knob rod is symmetrically threaded between the back of the transfer frame and the collecting frame.

[0010] Preferably, an inclined plate is fixedly connected to one side of the bottom of the transfer frame, and the top of the inclined plate is fixedly connected to the bottom of the support plate, and a reinforcing plate is fixedly installed between the inclined plate and the support plate.

[0011] Preferably, the external symmetrical locking and rotating connection of the rotating rod is a limiting block, and the top of the limiting block is fixedly connected to the inside of the mounting frame.

[0012] Preferably, the first conical tooth and the second conical tooth are meshed together, and the third conical tooth and the fourth conical tooth are meshed together.

[0013] Preferably, the outer side of the support frame is slidably connected to the inner side of the slot, and the top of the lifting plate is fixedly connected to the bottom of the support frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: A rapid loading device for circuit boards, specifically, is described below: The operation of a second servo motor drives the rotation of a rotating rod, the rotation of a third conical tooth drives the rotation of a fourth conical tooth, thereby driving the rotation of two sets of rotating rods. The rotation of the rotating rods drives the rotation of two sets of first conical teeth, the rotation of the first conical teeth drives the rotation of the second conical teeth, and the rotation of the second conical teeth drives the rotation of screws. At this time, the four screws rotate synchronously, achieving the effect of adjusting the height of the conveyor belt. The operation of the first servo motor drives the rotation of rotating rollers. Through the cooperation between the two sets of rotating rollers and the conveyor belt, the conveyor belt picks up the circuit boards processed on the conveyor belt. Subsequently, the conveyor belt transports the circuit boards to the carrier frame. The height-adjustable conveyor belt structure allows the transfer frame to flexibly adjust its own conveyor belt height according to the height of the circuit board production line conveyor equipment, quickly and accurately completing the docking, greatly reducing the adjustment time during the docking process. The reduced operational complexity significantly improves the efficiency of transferring circuit boards from the production line to the transfer frame, enabling rapid board loading. Furthermore, the adjustable conveyor belt height allows the transfer frame to adapt to varying heights on different production lines, enhancing its versatility and applicability. It can serve various production scenarios, improving equipment utilization. Workers manually place circuit boards of different specifications between corresponding partitions, ensuring a tight fit between the circuit board's exterior and the rubber pad. The worker then uses the handle to push the collection frame back into the transfer frame and finally secures it with a knob. This quick-extending and retractable collection frame design allows for convenient manual sorting and classification of circuit boards during loading, ensuring orderly storage of different specifications. This avoids the time-consuming process of sorting mismatched circuit board sizes during subsequent unloading, greatly improving unloading efficiency and accelerating the overall production process.

[0015] 1. The second servo motor drives the rotation of the rotating rod, which in turn drives the rotation of the third conical tooth, which in turn drives the rotation of the fourth conical tooth, which in turn drives the rotation of the transmission rod. The engagement between the third and fourth conical teeth drives the rotation of two sets of rotating rods. This rotation of the rotating rods drives the rotation of two sets of first conical teeth, which in turn drives the rotation of the second conical teeth, which in turn drives the rotation of the screws. At this point, all four screws rotate synchronously, achieving the effect of adjusting the conveyor belt height. The first servo motor drives the rotation of the rotating rollers. Through the engagement between the two sets of rotating rollers and the conveyor belt, the conveyor belt picks up the circuit boards, which are then transported to the support frame. The height-adjustable conveyor belt structure allows the transfer frame to flexibly adjust its conveyor belt height according to the height of the circuit board production line conveyor equipment, quickly and accurately completing the docking. This greatly reduces the adjustment time and operational complexity during the docking process, significantly improving the transfer efficiency of circuit boards from the production line to the transfer frame and achieving the effect of rapid circuit board loading. Moreover, the adjustable conveyor belt height allows the transfer frame to adapt to the height differences of different production lines, enhancing the versatility and applicability of the transfer frame. It can serve a variety of production scenarios and improve equipment utilization. When the support frame moves up and down, driving the carrier frame to move, the carrier frame slides inside the slot. At this time, the two sets of retractable rods and retractable springs retract or extend, thereby achieving the support effect when the carrier frame moves, improving the stability of subsequent sorting and loading of circuit boards at the top of the carrier frame. 2. Workers manually place circuit boards of different specifications between corresponding sized partitions, ensuring the circuit boards are tightly fitted to the rubber pads. Workers then use the handle to push the collection box back into the transfer box. Finally, workers use a knob to secure the collection box. This quick-expansion and retraction design allows workers to easily sort and classify circuit boards during loading, storing different specifications in an orderly manner. This avoids the time-consuming process of sorting mismatched circuit board sizes during unloading, significantly improving unloading efficiency and accelerating the entire production process. The quick-expansion and retraction function optimizes the use of internal space in the transfer box, expanding to increase storage space when sorting is needed and retracting to save space when not needed. This allows the transfer box to carry more circuit boards within a limited space, improving transportation efficiency and reducing transportation costs. Attached Figure Description

The first conical tooth 212 meshes with the second conical tooth 213, and the third conical tooth 217 meshes with the fourth conical tooth 218. The connection, through the height-adjustable conveyor belt 204 structure, allows the transfer frame 1 to flexibly adjust the height of its own conveyor belt 204 according to the height of the circuit board production line conveying equipment, and quickly and accurately complete the docking. This greatly reduces the adjustment time and operational complexity during the docking process, significantly improves the transfer efficiency of circuit boards from the production line to the transfer frame 1, and achieves the effect of rapid circuit board loading. Moreover, the height-adjustable conveyor belt 204 allows the transfer frame 1 to adapt to the height differences of different production lines, enhancing the versatility and applicability of the transfer frame 1, serving a variety of production scenarios, and improving equipment utilization. A retractable rod 219 is symmetrically fixedly connected between the bottom of the support frame 206 and the interior of the transfer frame 1, and a retractable spring 220 is sleeved on the outside of the retractable rod 219, thereby achieving the support effect when the support frame 206 moves, and improving the stability of the subsequent sorting and loading of the circuit board on the top of the support frame 206.

[0020] The collection component 3 includes a collection frame 301, which is slidably connected to the inside of one side of the transfer frame 1.

The collection frame 301 can be quickly extended and retracted. The 01 design allows staff to easily sort and classify circuit boards manually during the loading process, storing different specifications of circuit boards in an orderly manner. This avoids the time wasted on sorting due to the chaotic specifications of the circuit boards during subsequent unloading, greatly improving the efficiency of subsequent unloading and accelerating the turnover speed of the entire production process.

It can be expanded to increase storage space when sorting is needed and retracted to save space when not needed, allowing the transfer frame 1 to carry more circuit boards in a limited space, improving transportation efficiency and reducing transportation costs.

[0021] Working principle: Before using this rapid loading device for circuit boards, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 6As shown, firstly, the operator moves the transfer frame 1 to the conveyor attachment using the casters 104, so that the conveyor belt 204 aligns with the circuit board processing conveyor belt. Then, the operator operates the controller to drive the first servo motor 205 and the second servo motor 214. The operation of the second servo motor 214 drives the rotation of the rotating rod 211, which in turn drives the rotation of the third conical tooth 217. The rotation of the third conical tooth 217 drives the rotation of the fourth conical tooth 218, which in turn drives the rotation of the transmission rod 216. The interaction between the third conical tooth 217 and the fourth conical tooth 218 drives the rotation of both sets of rotating rods 211. The rotation of the rotating rod 211 drives the rotation of two sets of first conical teeth 212, which in turn drives the rotation of second conical teeth 213, which in turn drives the rotation of screws 209. At this time, all four screws 209 rotate synchronously. The threaded teeth on the surface of the screws 209 are designed according to the direction of rotation to ensure proper fit between the screws 209 and the threaded grooves 210, achieving the effect of adjusting the height of the lifting plate 208 and the conveyor belt 204. The operation of the first servo motor 205 drives the rotation of the rotating rollers 203. Through the cooperation between the two sets of rotating rollers 203 and the conveyor belt 204, the conveyor belt 204 lifts the circuit board... Circuit boards are received on the conveyor belt, and then the conveyor belt 204 transports the circuit boards to the carrier frame 206. The height-adjustable conveyor belt 204 structure allows the transfer frame 1 to flexibly adjust its own conveyor belt 204 height according to the height of the circuit board production line's conveyor equipment, quickly and accurately completing the docking. This greatly reduces adjustment time and operational complexity during the docking process, significantly improving the transfer efficiency of circuit boards from the production line to the transfer frame 1, achieving rapid circuit board loading. Furthermore, the adjustable height of the conveyor belt 204 allows the transfer frame 1 to adapt to the height differences of different production lines, enhancing its versatility and applicability. It can serve various production scenarios, improving equipment utilization. When the support frame 202 moves up and down, driving the carrier frame 206 to move, the carrier frame 206 slides inside the slot 101. At this time, the two sets of retractable rods 219 and retractable springs 220 retract or extend, thereby achieving the support effect when the carrier frame 206 moves, improving the stability of subsequent sorting and loading of the circuit board on top of the carrier frame 206. Through the cooperation between the inclined plate 221, the reinforcing plate 222 and the support plate 201, the mounting frame 207 can be made more stable during use. Through the design of the limit block 223, the rotation of the rotating rod 211 can be made more stable, reducing the probability of tooth disengagement between the first conical tooth 212 and the second conical tooth 213. When the circuit boards are transferred to the top of the support frame 206 via the conveyor belt 204, the operator manually places circuit boards of different specifications between the corresponding partitions 302. At this point, the circuit boards are tightly fitted against the rubber pads 303. After sorting the circuit boards, the operator operates the handle 304 to push the collection frame 301 back into the transfer frame 1. The L-plate 102 and the protrusions inside the transfer frame 1 support the upper and lower edges of the collection frame 301, ensuring that the collection frame 301 moves in one direction. Finally, the operator uses the knob 305 to fix the collection frame 301 in place. The quick-expansion and retraction collection box 301 design allows workers to easily sort and classify circuit boards during the board loading process, storing different specifications of circuit boards in an orderly manner. This avoids the time-consuming task of sorting out the circuit boards due to their chaotic specifications during subsequent unloading, greatly improving the efficiency of subsequent unloading and accelerating the turnover speed of the entire production process. The quick-expansion and retraction function of the collection box 301 optimizes the internal space utilization of the transfer box 1. It expands to increase storage space when sorting is needed and retracts to save space when not needed, allowing the transfer box 1 to carry more circuit boards in a limited space, improving transportation efficiency and reducing transportation costs.
