Description

Technical Field

[0001] This utility model relates to the field of PCB manufacturing technology, and in particular to a PCB lamination steel plate loading device. Background Technology

[0002] In the manufacturing process of PCBs (Printed Circuit Boards), hot presses are key equipment for achieving interlayer bonding. They apply specific temperatures, pressures, and times to press multi-layer PCB substrates and bonding materials together. In the hot press bonding process, the laminating steel plate, as a core component, plays a decisive role in the bonding quality. The laminating steel plate must meet high flatness requirements to ensure uniform stress on the interlayer contact surfaces of the PCB, effectively reducing the generation of defects such as bubbles and voids during the bonding process. Therefore, the laminating steel plate must be strictly protected from bumps, scratches, and other damage during loading and transportation to maintain its high-precision performance indicators. Currently, the loading of laminating steel plates in the industry mainly relies on traditional manual methods, where workers transport the laminating steel plates to the loading station of the hot press. Manual handling and loading methods have significant drawbacks. The laminating steel plates usually have a certain weight, and long-term manual handling not only leads to extremely high labor intensity for workers and easily causes safety hazards due to fatigue, but also makes it difficult to accurately control the force and angle during manual handling. Long-term operation can easily cause damage such as bumps and scratches on the edges of the laminating steel plates, directly affecting their flatness and thermal conductivity, which in turn leads to a decrease in PCB lamination quality and increases the PCB defect rate. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a PCB lamination stencil loading device that can reduce the labor intensity of workers and minimize damage to the lamination stencil, thereby improving the loading efficiency of the lamination stencil and ensuring the lamination quality of the PCB.

[0004] A PCB lamination steel plate loading device according to an embodiment of the present invention includes a frame; a linear conveyor device disposed on the frame, the end of which is configured to correspond to the loading station of a hot press; a transfer cart for supporting multiple lamination steel plates, the transfer cart being movable to the beginning of the linear conveyor device; and a handling device disposed on the frame, the handling device being located at the beginning of the linear conveyor device, the handling device being used to handle the lamination steel plates on the transfer cart to the beginning of the linear conveyor device, so that the linear conveyor device can transport the lamination steel plates to the loading station of the hot press.

[0005] It has at least the following beneficial effects: Workers can neatly place multiple pressed steel plates onto a transfer cart using a forklift, allowing the cart to support multiple plates. The worker then moves the transfer cart to the beginning of the linear conveyor on the frame and positions it precisely. Next, a handling device located at the beginning of the linear conveyor on the frame is activated, smoothly transferring each pressed steel plate from the transfer cart to the conveying surface at the beginning of the linear conveyor. Once at the beginning of the linear conveyor, the pressed steel plate is conveyed along a straight line towards the end of the linear conveyor. Since the end of the linear conveyor corresponds to the loading station of the hot press, the pressed steel plate is accurately delivered to the loading station of the hot press, completing one pressing steel plate loading operation. Subsequent loading can be achieved by repeatedly retrieving materials from the transfer cart and conveying them by the linear conveyor using the handling device. The transfer cart in this PCB lamination stencil loading equipment enables batch transfer of lamination stencils and, in conjunction with the handling device, replaces the traditional manual handling and loading method, significantly reducing the labor intensity of workers. At the same time, the stable conveying of the linear conveyor effectively reduces damage such as bumps and scratches to the lamination stencils during the transfer and loading process, thereby improving the loading efficiency of the lamination stencils and ensuring the lamination quality of the PCB.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figure 1 This utility model discloses a PCB lamination steel plate loading equipment, including a frame 400, a linear conveyor 100, a transfer vehicle 300 and a handling device 200.

[0021] A linear conveyor 100 is mounted on the frame 400, and its end is positioned to correspond to the loading station of the hot press. A transfer cart 300 is used to support multiple pressed steel plates and can move to the beginning of the linear conveyor 100. A handling device 200 is mounted on the frame 400 and is positioned at the beginning of the linear conveyor 100. The handling device 200 is used to move the pressed steel plates from the transfer cart 300 to the beginning of the linear conveyor 100, so that the linear conveyor 100 can transport the pressed steel plates to the loading station of the hot press.

[0022] Understandably, workers can use a forklift to neatly place multiple pressed steel plates onto the transfer cart 300, allowing the cart 300 to support them. Then, the worker moves the transfer cart 300 to the starting position of the linear conveyor 100 on the frame 400 and positions it precisely. Next, the handling device 200, located on the frame 400 at the starting end of the linear conveyor 100, is activated, smoothly transferring a single pressed steel plate from the transfer cart 300 to the conveying surface at the starting end of the linear conveyor 100. After being transported to the starting end of the linear conveyor 100, the pressed steel plate is conveyed along a straight line towards the end of the linear conveyor 100 under the conveying action of the linear conveyor 100. Because the end of the linear conveyor 100 is positioned corresponding to the loading station of the hot press, the pressed steel plate can be accurately conveyed to the loading station of the hot press to complete one loading operation. Subsequently, the material can be repeatedly retrieved from the transfer cart 300 and conveyed by the linear conveyor 100 via the handling device 200, achieving continuous loading. The transfer cart 300 in this PCB pressed steel plate loading equipment enables batch transfer of pressed steel plates and, in conjunction with the handling device 200, replaces the traditional manual handling and loading method, significantly reducing the labor intensity of workers. Simultaneously, the stable conveying of the linear conveyor 100 effectively reduces damage such as bumps and scratches to the pressed steel plates during transfer and loading, thereby improving the loading efficiency of the pressed steel plates and ensuring the pressing quality of the PCB.

[0023] As one embodiment of this utility model, the transfer vehicle 300 can be a common AGV transfer vehicle 300, which is an automated guided vehicle equipped with electromagnetic or optical automatic guidance devices. The AGV transfer vehicle 300 does not require manual operation and can travel along a prescribed guidance path. Workers use forklifts to neatly place multiple pressed steel plates onto the AGV transfer vehicle 300. After loading, the control system sends a running command to the AGV transfer vehicle 300. The AGV transfer vehicle 300 automatically travels to the beginning position of the linear conveyor 100 on the frame 400 according to the preset path or navigation system, and achieves precise docking through the positioning device. Subsequently, the handling device 200 starts and smoothly transports a single pressed steel plate to the beginning of the linear conveyor 100. Then, the linear conveyor 100 transports the pressed steel plate along a straight line towards the end of the linear conveyor 100. Finally, the pressed steel plate is precisely transported to the loading station of the hot press, completing the loading process. After completing the transfer of the current batch of pressed steel plates, the AGV transfer vehicle 300 can automatically return to the loading area to wait for the next loading according to the instructions. Further details will not be provided here.

[0024] It should be explained that when the linear conveyor 100 transports the pressing steel plate to the end, the hot press's material handling mechanism (such as a robotic arm or pushing device) is activated, precisely grabbing or receiving the pressing steel plate at the end of the linear conveyor 100 and transferring it to a preset station between the heating plates. The hot press's drive system drives the heating plates to close, applying pressure according to set parameters and conducting heat through the heating plates to perform the pressing operation on the pressing steel plate and the PCB to be pressed. After pressing is completed, the drive system controls the heating plates to separate, and the material handling mechanism operates again, removing the pressed steel plate and PCB assembly from the station and transferring it to the conveyor device for the next process, thus completing the entire material handling, pressing, and unloading process. Hot presses are common equipment in the PCB manufacturing industry, and their structure and operation process will not be further elaborated here.

[0025] refer to Figure 2 and Figure 3The conveying device 200 includes an adsorption mechanism 210, a lifting drive mechanism 220, and a linear drive mechanism 230. The adsorption mechanism 210 is used to adsorb or release the pressed steel plate, the lifting drive mechanism 220 is used to drive the adsorption mechanism 210 to move up and down, and the linear drive mechanism 230 is used to drive the adsorption mechanism 210 to move along a conveying direction parallel to the linear conveying device 100. In this embodiment of the present invention, the linear conveying device 100 is used to convey the pressed steel plate from back to front, and the linear drive mechanism 230 is used to drive the adsorption mechanism 210 to move in a front-back direction. Understandably, once the transfer cart 300 moves to the beginning of the linear conveyor 100 and is positioned, the linear drive mechanism 230 is activated, driving the adsorption mechanism 210 to move to the position above the transfer cart 300 corresponding to the pressed steel plate. Subsequently, the lifting drive mechanism 220 operates, causing the adsorption mechanism 210 to descend to a height that is in contact with the surface of the pressed steel plate, and the adsorption mechanism 210 adsorbs the pressed steel plate. Then, the lifting drive mechanism 220 drives the adsorption mechanism 210 to rise, smoothly lifting the pressed steel plate from the transfer cart 300. Afterward, the linear drive mechanism 230 runs again, driving the adsorption mechanism 210, which is adsorbing the steel plate, to move above the beginning of the linear conveyor 100. The lifting drive mechanism 220 then drives the adsorption mechanism 210 to descend, gently placing the pressed steel plate on the beginning of the linear conveyor 100. Finally, the adsorption mechanism 210 releases the pressed steel plate, allowing the linear conveyor 100 to transport the pressed steel plate to the loading station of the hot press. After the adsorption mechanism 210 releases the pressed steel plate, the lifting drive mechanism 220 drives the adsorption mechanism 210 to rise and reset, and the linear drive mechanism 230 drives the adsorption mechanism 210 back to the top of the transfer vehicle 300 to wait for the next material picking, thus completing a single steel plate handling operation. The above process is repeated to achieve continuous handling.

[0026] refer to Figure 2The linear drive mechanism 230 includes a cylinder 231, a mounting plate 232, two first slide rails 233, and two first sliders. The two first slide rails 233 are parallel to the conveying direction of the linear conveying device 100. The two first sliders are mounted on the mounting plate 232 and are slidably connected to the two first slide rails 233 respectively. The cylinder body of the cylinder 231 is connected to the frame 400, and the piston rod of the cylinder 231 is connected to the mounting plate 232. The lifting drive mechanism 220 is mounted on the mounting plate 232, and the adsorption mechanism 210 is vertically connected to the mounting plate 232. The output end of the lifting drive mechanism 220 is connected to the adsorption mechanism 210. Understandably, the piston rod of cylinder 231 extends and pushes the mounting plate 232 to move, causing the adsorption mechanism 210 and the lifting drive mechanism 220 on the mounting plate 232 to move to the position above the transfer car 300 corresponding to the pressed steel plate; then the lifting drive mechanism 220 actuates, and its output end drives the adsorption mechanism 210 to descend, causing the adsorption mechanism 210 to move to a height that is in contact with the surface of the pressed steel plate, thereby enabling the adsorption mechanism 210 to adsorb the pressed steel plate; then the lifting drive mechanism 220 drives the adsorption mechanism 210 to rise, and the piston rod of cylinder 231 of the linear drive mechanism 230 retracts, pulling the mounting plate 232, the adsorption mechanism 210 and the lifting drive mechanism 220 to move above the beginning of the linear conveyor 100; the lifting drive mechanism 220 then drives the adsorption mechanism 210 to descend, and the adsorption mechanism 210 releases the pressed steel plate, so that the linear conveyor 100 can transport the pressed steel plate to the loading station of the hot press.

[0027] refer to Figure 2 and Figure 3The lifting drive mechanism 220 includes a first motor 221, a lead screw 222, a nut 223, two second slide rails 224, and two second sliders 225. The two second slide rails 224 are parallel to the vertical direction, and the two second sliders 225 are connected to the adsorption mechanism 210. The two second sliders 225 are slidably connected to the two second slide rails 224 respectively. The first motor 221 is mounted on the mounting plate 232. The lead screw 222 is parallel to the vertical direction. The nut 223 is connected to the adsorption mechanism 210. The output end of the first motor 221 is connected to the upper end of the lead screw 222. The lead screw 222 is threadedly connected to the nut 223. Understandably, when the linear drive mechanism 230 is activated, it drives the lifting drive mechanism 220 and the adsorption mechanism 210, both mounted on the mounting plate 232, to move along the conveying direction parallel to the linear conveyor 100 to the position above the transfer car 300 corresponding to the pressed steel plate. Subsequently, the first motor 221 is activated, its output driving the lead screw 222 to rotate. Because the lead screw 222 is threadedly connected to the nut 223, and the nut 223 is connected to the adsorption mechanism 210, the rotation of the lead screw 222 drives the nut 223 to smoothly descend along the second slide rail 224, moving the adsorption mechanism 210 to a height that contacts the surface of the pressed steel plate, whereupon the adsorption mechanism 210 adheres to the pressed steel plate. Then, the first motor 221 rotates in the opposite direction. The screw 222 is driven to rotate in the opposite direction, and the nut 223 drives the adsorption mechanism 210 to rise along the second slide rail 224, smoothly lifting the pressed steel plate from the transfer car 300. Then, the linear drive mechanism 230 drives the mounting plate 232 to move in the opposite direction along the first slide rail 233, moving the adsorption mechanism 210 holding the steel plate to above the beginning of the linear conveyor 100. The first motor 221 rotates in the forward direction, driving the screw 222 to rotate, and the nut 223 drives the adsorption mechanism 210 to descend along the second slide rail 224, so that the pressed steel plate is gently placed on the conveying surface of the linear conveyor 100. Finally, the adsorption mechanism 210 releases the pressed steel plate, so that the linear conveyor 100 conveys the pressed steel plate to the loading station of the hot press.

[0028] refer to Figure 3The adsorption mechanism 210 includes a support 211 and multiple suction cups 212. The support 211 is connected to a nut 223 and two second sliders 225, and the multiple suction cups 212 are all connected to the support 211. In this embodiment of the invention, the adsorption mechanism 210 also includes a negative pressure generator and a solenoid valve. The negative pressure generator generates negative pressure, and the solenoid valve controls the on / off state of the negative pressure. When it is necessary to adsorb the pressed steel plate, the solenoid valve opens, and the negative pressure generated by the negative pressure generator is transmitted to the multiple suction cups 212 through the pipeline. Under the action of negative pressure, the suction cups 212 tightly adhere to the surface of the pressed steel plate, thereby adsorbing the pressed steel plate. When it is necessary to release the pressed steel plate, the solenoid valve closes, the negative pressure disappears, outside air enters the suction cups 212, and the suction cups 212 separate from the surface of the pressed steel plate, completing the release action. The support 211 serves to fix the multiple suction cups 212, ensuring that the suction cups 212 are subjected to uniform force and stably adsorb the pressed steel plate. The adsorption mechanism 210 is a common adsorption gripping mechanism, which will not be described in detail here.

[0029] refer to Figure 1 The linear conveyor 100 includes a belt 110, which is rotatably connected to the frame 400. The belt 110 is used to convey the pressed steel plate, and its width is greater than the width of the pressed steel plate. In this embodiment, the belt 110 is parallel to the front-to-back direction. It is understood that after the transfer cart 300 moves to the beginning of the linear conveyor 100 and is positioned, the handling device 200 transports the pressed steel plate from the transfer cart 300 onto the belt 110 of the linear conveyor 100. The belt 110 rotates and drives the pressed steel plate placed on it to the end, ultimately conveying the pressed steel plate to the loading station of the hot press to complete the loading process. The belt 110 can transport the pressed steel plate, and its width is greater than that of the pressed steel plate, providing a stable support surface for the plate and preventing it from shifting or falling during transport, thus ensuring smooth transport. The wider belt 110 can also accommodate pressed steel plates of different sizes, improving the versatility of the linear conveyor 100. In this embodiment, the linear conveyor 100 further includes a drive wheel, a driven wheel, a third motor, and a tensioning mechanism. The drive wheel and driven wheel are rotatably connected to the frame 400 and are spaced apart. The belt 110 is wound around the drive wheel and driven wheel. The output end of the third motor is connected to the drive wheel, and the tensioning mechanism is used to adjust the tension of the belt 110. During operation, the third motor starts and drives the drive wheel to rotate. Under the action of friction, the drive wheel drives the belt 110 and the driven wheel to rotate synchronously. The tensioning mechanism adjusts the tension of the belt 110 to ensure that the belt 110 is in close contact with the drive wheel and the driven wheel. When the pressed steel plate is placed on the beginning of the belt 110, the pressed steel plate is smoothly transported to the end with the cyclical movement of the belt 110, realizing the continuous transport of the pressed steel plate.

[0030] refer to Figure 4 and Figure 5The transfer cart 300 includes a plate body 310, a handle 320, two front wheels 330, and two rear wheels 340. The two front wheels 330 and two rear wheels 340 are rotatably connected to the plate body 310, allowing the plate body 310 to move on the ground via the two front wheels 330 and two rear wheels 340. The plate body 310 supports multiple pressed steel plates. The lower end of the handle 320 is hinged to the plate body 310, and the handle 320 is positioned near the two front wheels 330. Understandably, workers can flip the handle 320 upwards to rotate it around its hinge point with the plate body 310 to a comfortable gripping angle, and then manually or with a forklift, neatly place the multiple pressed steel plates onto the plate body 310. Next, the worker can grasp the handle 320 and pull the plate 310. The plate 310, with the help of the two front wheels 330 and two rear wheels 340, moves the entire transfer cart 300 on the ground, allowing the plate 310 to deliver multiple pressed steel plates to the beginning of the linear conveyor 100. After positioning, it can cooperate with the handling device 200 to perform the material removal operation of the pressed steel plates. After material removal, the handle 320 can be pulled again to move the transfer cart 300 to the designated position. If storage is required, the handle 320 can be flipped downwards to be close to the plate 310, reducing the space occupied by the transfer cart 300. (Reference) Figure 5 Both front wheels 330 are swivel casters. Understandably, the use of swivel casters on the two front wheels 330 allows the transfer cart 300 to flexibly adjust its direction during movement. Workers can easily change the travel path of the transfer cart 300 without making significant turns, significantly improving the flexibility and ease of operation of the transfer cart 300. Swivel casters are common types of wheels and will not be discussed further here.

[0031] refer to Figure 4 The transfer cart 300 also includes a tension spring 350. One end of the tension spring 350 is connected to the plate 310, and the other end is connected to the handle 320. The tension spring 350 can pull the handle 320 to swing upward. Understandably, when the worker releases the handle 320, the elastic restoring force of the tension spring 350 will pull the handle 320 to automatically swing upward and return to its original position, preventing the handle 320 from drooping due to its own weight and affecting the movement or operation of the transfer cart 300. On the other hand, when the handle 320 is not in use, the tension spring 350 can keep the handle 320 in an raised state, reducing the impact of the handle 320 with the ground or other objects, thus improving the convenience and safety of using the transfer cart 300.

[0032] refer to Figure 5The transfer cart 300 also includes a second motor 360 and a connecting shaft 370. The second motor 360 is mounted on the plate 310, and both ends of the connecting shaft 370 are connected to two rear wheels 340 respectively. The second motor 360 can drive the connecting shaft 370 to rotate, thereby causing the two rear wheels 340 to rotate. It can be understood that the second motor 360 can drive the two rear wheels 340 to rotate synchronously by driving the connecting shaft 370, providing power to the transfer cart 300. This eliminates the need for workers to pull the cart continuously, significantly reducing the labor intensity of workers during the transfer of the pressed steel plates and improving the transfer efficiency. Furthermore, the drive of the second motor 360 enables the transfer cart 300 to maintain a stable speed, avoiding speed fluctuations caused by uneven force when workers pull the cart, reducing the swaying of the steel plates during transfer, and lowering the risk of collisions between the pressed steel plates. In this embodiment of the invention, a drive sprocket is mounted on the output shaft of the second motor 360, and a driven sprocket is mounted in the middle of the connecting shaft 370. A chain is wound around the drive sprocket and the driven sprocket and kept taut. When the second motor 360 starts, it drives the drive sprocket to rotate. The drive sprocket drives the driven sprocket and the connecting shaft 370 to rotate together via the chain, thereby causing the two rear wheels 340 at both ends of the connecting shaft 370 to rotate under the driving force, thus realizing the movement of the transfer vehicle 300.

[0033] In this embodiment of the invention, the frame 400 is provided with two first magnetic attractors, which are positioned near the beginning of the linear conveyor 100. Two second magnetic attractors are provided on the side of the plate 310. The two first magnetic attractors can magnetically attract each other with the two second magnetic attractors, so that the plate 310 and the frame 400 remain in contact. It is understood that the magnetic attraction between the two first magnetic attractors on the frame 400 and the two second magnetic attractors on the side of the plate 310 allows the plate 310 to be quickly and precisely aligned with the frame 400 when the transfer cart 300 moves to the beginning of the linear conveyor 100, achieving rapid positioning of the transfer cart 300. This magnetic positioning method eliminates the need for repeated alignment adjustments by workers, reducing the time spent on positioning the transfer cart 300. On the other hand, the magnetic attraction allows the transfer cart 300 to remain relatively fixed to the frame 400 during material handling, preventing the transfer cart 300 from shifting due to external forces or vibrations. This ensures that the handling device 200 can accurately pick up materials from the transfer cart 300, improving the stability and accuracy of the material handling operation and effectively guaranteeing the smooth progress of subsequent material loading processes. The first and second magnetic components can be common magnets.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
