Description

Technical Field

[0001] This utility model relates to the field of PCB board manufacturing equipment technology, and in particular to a feeding machine. Background Technology

[0002] In the traditional PCB cutting process, a cutting machine is usually used to cut PCB boards. When loading the cutting machine, the boards are usually lifted manually. However, because the double auxiliary materials are large, two people are needed to lift the boards, which results in a large workload. Moreover, the boards are large, and manual lifting can easily damage them due to uneven force. Therefore, there is an urgent need for a device that can replace manual handling and loading of the boards. Utility Model Content

[0003] The purpose of this utility model is to provide a feeding machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

A transfer device having a suction and transfer end that is movable between the lifting platform and the stacking space.

[0005] As can be seen from the above, when using the loading machine to transport workpieces to the cutting machine, firstly, the forklift transfers all the stacked workpieces to the lifting platform. Then, the forklift can leave directly to the warehouse to retrieve the next batch of workpieces. The transfer device lifts the workpieces from the lifting platform by the suction transfer end and places them in the stacking table. They are then transported to the next process for cutting by the conveying assembly. After the forklift transports the next batch of workpieces to the lifting platform, it can directly store the next batch of workpieces on the lifting platform and leave again to transport the next batch of workpieces.

[0006] The technical solution has at least the following beneficial effects: First, by transporting the workpiece through the suction and transfer end of the transfer device, the workload of manual handling by workers is reduced, the production speed is greatly accelerated, and the equipment downtime is reduced. Second, the lifting platform can be used as a temporary storage device for workpieces, instead of directly transporting the workpieces from the forklift to the stacking platform through the transfer device, so that the forklift can continue to transport after putting down the workpiece, further reducing the waiting time.

[0007] As a further improvement to the above technical solution, the conveying assembly includes a pusher plate, which is capable of moving in and out of the stacking space along the stacking table.

[0008] As a further improvement to the above technical solution, the stacking table is provided with a first alignment component. The first alignment component includes a first baffle and a first alignment drive member. With the moving direction of the pusher plate as the first direction, the first baffle and the first alignment drive member are located on opposite sides of the stacking space along the first direction. The first alignment drive member has a first pushing end, which can move in the stacking space parallel to the first direction. The first baffle can move in the vertical direction of the stacking table.

[0009] As a further improvement to the above technical solution, the stacking platform is provided with a second alignment component. The second alignment component includes a second baffle and a second alignment drive member. The second baffle and the second alignment drive member are located on opposite sides of the stacking space along a horizontal direction perpendicular to the first direction. The second alignment drive member has a second pushing end, which is capable of moving along a horizontal direction perpendicular to the first direction.

[0010] As a further improvement to the above technical solution, the stacking platform is provided with multiple omnidirectional balls at the bottom of the stacking space.

[0011] As a further improvement to the above technical solution, the transfer device includes a transfer drive assembly, a transfer frame, and a first suction cup. The first suction cup is provided at the bottom of the transfer frame, and the suction transfer end is the suction end of the first suction cup. The transfer drive assembly is used to drive the transfer frame to move between the lifting frame and the stacking platform.

[0012] As a further improvement to the above technical solution, the transfer frame is provided with a second suction cup on one side of the first suction cup, which can reciprocate in the vertical direction of the transfer frame, and the second suction cup has a shaking suction end.

[0013] As a further improvement to the above technical solution, the lifting frame also includes a base plate, a first fork arm, a second fork arm, and a lifting drive component. The first fork arm and the second fork arm are intersected and rotatably connected. One end of the first fork arm is rotatably connected to the base plate, and the other end is rotatably connected to the lifting platform. One end of the second fork arm can slide on the base plate, and the other end is slidably connected to the lifting platform. The lifting drive component is used to drive the end of the second fork arm connected to the base plate to slide horizontally.

[0014] As a further improvement to the above technical solution, a limiting block is provided on the base plate, and the second fork arm is installed at one end of the base plate and the side away from the first fork arm can move to abut against the limiting block.

[0015] As a further improvement to the above technical solution, the first fork arm and the second fork arm form a fork arm assembly, and the fork arm assemblies are provided on both sides of the bottom plate, forming a clearance space between the two fork arm assemblies for the forklift to enter.

[0023] Reference Figure 1 The feeding machine provided in this application includes a lifting frame 1, a stacking table 2 and a transfer device 3. The lifting frame 1 is used to temporarily store the sheet material transported by the forklift. The stacking table 2 is used to align the sheet material and transport it to the cutting machine in the next process to cut the sheet material. The transfer device 3 is used to transfer the sheet material from the lifting frame 1 to the stacking table 2.

[0024] Specifically, refer to Figure 1 The lifting frame 1 includes a lifting platform 11, which can be connected to a transfer forklift used in conjunction with a loading machine. A stacking platform 2 is installed on the side of the lifting platform 11 in the horizontal direction away from the connection between the forklift and the lifting platform 11. A stacking space 201 is formed on the stacking platform 2. The stacking platform 2 is provided with a conveying assembly 21. The conveying end of the conveying assembly 21 is connected to a cutting machine used in conjunction with the loading machine. A transfer device 3 has a suction transfer end that can move between the lifting platform 11 and the stacking space 201.

[0025] As can be seen from the above, when using the loading machine to transport workpieces to the cutting machine, firstly, the forklift transfers all the stacked workpieces to the lifting platform 11. Then, the forklift can leave directly to the warehouse to retrieve the next batch of workpieces. The transfer device 3 lifts the sheet metal from the lifting platform 11 through the suction transfer end and places it into the stacking table 2. The stacking table 2 can hold multiple sheets of sheet metal. After the multiple sheets of sheet metal are stacked, they are transported to the next process for cutting with the conveying component 21. After the forklift transports the next batch of workpieces to the lifting platform 11, it can directly store the next batch of workpieces on the lifting platform 11 and leave again to transport the next batch of workpieces.

[0026] The technical solution has at least the following beneficial effects: First, by transporting the workpiece through the suction and transfer end of the transfer device 3, the workload of manual handling by workers is reduced, the production speed is greatly accelerated, and the equipment standby time is reduced. Second, the lifting platform 11 can be used as a temporary storage device for workpieces, instead of directly transporting the workpieces from the forklift to the stacking platform 2 through the transfer device 3, so that the forklift can continue to transport after putting down the workpiece, further reducing the waiting time.

[0027] In this embodiment, refer to Figure 2 In order to stably push the boards, the conveying assembly 21 includes a pusher plate 211 and a pusher drive. The pusher plate 211 can move along the stacking table 2 in the direction of horizontal entry and exit from the stacking space 201. By adopting the above technical solution, the pusher plate 211 with sufficient length can push multiple stacked boards as a whole, improving the stability of the push. Specifically, the pusher drive is used to drive the pusher plate 211 to move on the stacking table 2.

[0028] After stacking multiple sheets, the projections of these sheets onto the plane of the stacking table 2 may partially overlap, affecting the feeding action of the pusher plate 211. Therefore, referring to... Figure 1 and Figure 2 This application provides a first alignment component 22 and a second alignment component 23 to align multiple stacked plates on two sets of opposite sides, thereby improving the pushing stability of the pusher plate 211.

[0029] Specifically, refer to Figure 2 and Figure 3The first alignment component 22 includes a first baffle 221 and a first alignment drive 222. With the moving direction of the pusher plate 211 as the first direction, the first baffle 221 and the first alignment drive 222 are located on opposite sides of the stacking space 201 along the first direction. The first alignment drive 222 has a first pushing end, which can move in the stacking space 201 parallel to the first direction. The first baffle 221 can move in the vertical direction of the stacking table 2. Specifically, the first baffle 221 can be driven by a lifting cylinder 2211 or other drive components to be raised above the upper surface of the stacking table 2 or lowered below the upper surface of the stacking table 2.

[0030] As can be seen from the above, through the cooperation of the first alignment drive 222 and the first baffle 221, multiple plates are arranged so that the two sides of plates of the same specification are aligned in the first direction, which makes it easy for the pusher plate 211 to transport the stacked plates to the cutting machine in one go. Furthermore, the first baffle 221, which can move up and down, can be raised to provide a reference for the alignment operation when the plates need to be aligned, and can be completely lowered to provide a path for the movement of the plates when the plates need to be transported.

[0031] Furthermore, refer to Figure 2 and Figure 3 The first baffle 221 can slide along the first direction on the stacking table 2, thereby cooperating with the pusher plate 211 to change the length of the stacking space 201 in the first direction, so as to adapt to different specifications of plates.

[0032] Furthermore, refer to Figure 2 The first alignment drive 222 is mounted on the pusher plate 211. The first push end can extend into or out of the stacking space 201 along the first direction on the pusher plate 211, thereby pushing the stacked multiple plates with a short stroke, so that the side of the plate away from the first push end abuts against the first baffle 221, thereby realizing the alignment of multiple plates.

[0033] This design integrates the first alignment drive 222 onto the pusher plate 211, reducing the installation space required for the first alignment drive 222 on the stacking table 2. This allows the pusher plate 211 to be extended to the maximum extent, thus having sufficient length to push various specifications of plates on the stacking table 2, improving the applicability of the stacking table 2 to different specifications of plates. Furthermore, after the pusher plate 211 moves, the first alignment drive 222 can move with the pusher plate 211, reducing the travel of the first pusher end itself, thereby reducing the cost of the first alignment drive 222.

[0034] In some embodiments, refer to Figure 2The second alignment component 23 includes a second baffle 231 and a second alignment drive member 232. The second baffle 231 and the second alignment drive member 232 are located on opposite sides of the stacking space 201 along a horizontal direction perpendicular to the first direction. The second alignment drive member 232 has a second pushing end, which is capable of moving along a horizontal direction perpendicular to the first direction.

[0035] Specifically, a side baffle 24 is provided on one side of the stacking table 2 along the first direction. A second alignment drive member 232 is installed on the side baffle 24, and a second baffle 231 is located on the opposite side of the side baffle 24. The second alignment drive member 232 and the second baffle 231 can restrict the movement of the sheet material along the horizontal direction perpendicular to the first direction.

[0036] As can be seen from the above, the second alignment drive 232 can level the sides of the material plate located at the two ends perpendicular to the first direction, and make the material plate on the pushing path of the pusher plate 211, so as to prevent the pusher plate 211 from only contacting part of the side of the material plate when pushing, which would cause uneven pushing force and deviation of the material plate movement path.

[0037] In this embodiment, the horizontal projection shape of the stacking table 2 is rectangular. The first baffle 221, the second baffle 231, the pusher plate 211, and the side baffle 24 are on the four sides of the stacking table 2. The first baffle 221, the second baffle 231, the pusher plate 211, and the side baffle 24 form a stacking space 201, thereby limiting the material plate during the alignment operation and preventing the material plate from falling off the stacking space 201.

[0038] In this embodiment, the first alignment drive 222, the second alignment drive 232, and the pusher drive are all linear drive mechanisms, and this application embodiment does not specifically limit them.

[0039] As a further implementation method, refer to Figure 2 The stacking table 2 has multiple omnidirectional balls at the bottom of the stacking space 201 (only the mounting holes of the omnidirectional balls on the stacking table 2 are shown in the attached drawings of this embodiment, and the bodies of the omnidirectional balls are not shown). Specifically, the omnidirectional balls are set in the plane of the stacking space 201 on the upper surface of the stacking table 2, away from other parts such as the first pushing end, the second pushing end and other structures. When the transfer device 3 transfers the board material to the stacking table 2, the board material directly contacts the spherical surface of the omnidirectional balls on the stacking table 2, thereby greatly reducing the friction between the board material and the table surface of the stacking table 2, so that it can move smoothly during the alignment operation and the process of conveying to the cutting machine.

[0040] In some embodiments, refer to Figure 1 and Figure 4The transfer device 3 includes a movable frame 31, a transfer drive assembly, a transfer frame 32, and a first suction cup 33. The transfer frame 32 and the transfer drive assembly are mounted on the movable frame 31. The first suction cup 33 is provided at the bottom of the transfer frame 32, and the suction transfer end is the suction end of the first suction cup 33. The transfer drive assembly is used to drive the transfer frame 32 to move between the lifting frame 1 and the stacking platform 2.

[0041] Specifically, the transfer frame 32 is plate-shaped, and multiple sets of first suction cups 33 are arranged along its length. The multiple first suction cups 33 in each set are arranged along the width of the transfer frame 32. The transfer drive assembly includes a horizontal transfer drive 35 and a vertical transfer drive 36. The horizontal transfer drive 35 is mounted on the moving frame 31, and the vertical transfer drive 36 is mounted on the moving end of the horizontal transfer drive 35. The transfer frame 32 is mounted on the moving end of the vertical transfer drive 36. When the transfer frame 32 needs to be moved to pick up the plate, the horizontal transfer drive... The vertical transfer drive 36 drives the transfer frame 32 to move horizontally until it reaches the stacking table 2 or the lifting table 11. Then, the vertical transfer drive 36 drives the moving frame to descend until the first suction cup 33 abuts against the board. Then, the vertical transfer drive 36 drives the transfer frame 32 and the board to move upward. The horizontal transfer drive 35 drives the board to move horizontally to the stacking table 2 or the lifting table 11 through the vertical transfer drive 36 and the transfer frame 32. In this embodiment, the structure of the horizontal transfer drive 35 and the vertical transfer drive 36 is not specifically limited.

[0042] Because the sheets are flat, adjacent sheets stacked on the lifting platform 11 may be pressed tightly together due to the vacuum. Therefore, refer to... Figure 4 In this application, the transfer frame 32 is provided with a second suction cup 34 on one side of the first suction cup 33, which can reciprocate in the vertical direction. The second suction cup 34 has a shaking suction end. Specifically, the transfer frame 32 has a shaking drive 341, which can be any linear drive. The shaking drive 341 has a shaking drive end that can move in the vertical direction. The second suction cup 34 is mounted on the shaking drive end. When the shaking drive 341 is activated, the second suction cup 34 can move in the vertical direction. When the first suction cup 33 and the second suction cup 34 are not in operation, the shaking suction end and the suction transfer end are flush with the downward end.

[0043] As can be seen from the above, when the first suction cup 33 and the second suction cup 34 simultaneously pick up the board material, the shaking drive 341 is activated to drive the second suction cup 34 to move up and down, ensuring that air enters between the picked-up board material and the adjacent board material below, so that the two boards material that are close to each other are separated, reducing the risk of the unpicked board material falling off during the transfer process.

[0044] In some embodiments, refer to Figure 1and Figure 5 The lifting frame 1 includes a base plate 14, a first fork arm 12, a second fork arm 13, and a lifting drive component. The first fork arm 12 and the second fork arm 13 are intersected and rotatably connected. One end of the first fork arm 12 is rotatably connected to the base plate 14, and the other end is rotatably connected to the lifting platform 11. One end of the second fork arm 13 can slide on the base plate 14, and the other end is slidably connected to the lifting platform 11. The lifting drive component is used to drive the end of the second fork arm 13 connected to the base plate 14 to slide horizontally. Specifically, the lifting drive component is a linear drive component. The lifting drive component includes a hydraulic cylinder, which is rotatably connected to the base plate 14, and the output end of the hydraulic cylinder is rotatably connected to the second fork arm 13.

[0045] As described above, the lifting drive pushes one end of the second fork arm 13 to slide on the base plate 14, so that the other end of the second fork arm 13 pushes the lifting platform 11 to rise and fall relative to the base plate 14. When the forklift places the board material transported from the warehouse, the lifting platform 11 is lowered relative to the base plate 14, so that the height of the highest point of the multiple boards stacked on the lifting platform 11 is reduced, leaving space between the highest board material and the transfer frame 32, so that the transfer frame 32 can move smoothly. At the same time, when the number of boards on the lifting platform 11 gradually decreases, the lifting drive drives the second fork arm 13 to slide on the base plate 14, so that the other end of the second fork arm 13 rotates upward, lifting the lifting platform 11 so that it rises relative to the base plate 14, thereby raising the multiple boards stacked on the lifting platform 11, so that the uppermost board material reaches the lowest height that the transfer frame 32 can reach after being driven by the vertical transfer drive 36, so that the first suction cup 33 and the second suction cup 34 can pick up and transfer it.

[0046] Furthermore, a limit block 15 is provided on the base plate 14. The second fork arm 13 is installed at one end of the base plate 14 and on the side away from the first fork arm 12, and can move to abut against the limit block 15. The limit block 15 limits the second fork arm 13 to prevent the second fork arm 13 from moving excessively and causing lifting failure.

[0047] Furthermore, the first fork arm 12 and the second fork arm 13 form a fork arm assembly. Fork arm assemblies are provided on both sides of the base plate 14. A clearance space is formed between the two fork arm assemblies for the forklift to enter. Since existing forklifts have extended forks, the clearance space is used to avoid the forks and prevent the forklift from hitting the fork arm assembly. At the same time, the fork arm assemblies on both sides can also improve the lifting stability of the lifting platform 11.

[0048] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
