Description

Technical Field

[0001] This application relates to the field of material feeding, and in particular to a feeding device for tin foil sealing sheets. Background Technology

[0002] In the use of loose powder, aluminum foil sealing sheets play a crucial role. These sheets effectively isolate the loose powder from external air and moisture, maintaining its quality and performance stability.

[0003] Reference Figure 1 The foil sealing sheet includes a circular piece 16 and a connecting piece 17 integrally formed on the circular piece 16, and both the circular piece 16 and the connecting piece 17 are made of foil. In addition, the end of the connecting piece 17 is designed to be arc-shaped, which can effectively prevent the foil connecting piece from scratching the user.

[0004] In traditional powder assembly devices, the feeding of tin foil sealing sheets is achieved by controlling the extension and retraction of a cylinder piston rod. Specifically, a suction nozzle is fixed to the piston rod, and the tin foil sealing sheet is picked up by extension and retraction. Then, a moving component transports it to the designated feeding position.

[0005] However, traditional feeding methods have significant drawbacks. During the tin foil sealing sheet suction process, the overall height of the unloaded sheet gradually decreases, requiring the cylinder piston rod to continuously extend its extension and retraction stroke. This increases the burden on the cylinder, shortens its service life, and reduces the accuracy of the suction action, thus affecting the working efficiency and quality of the feeding device. Utility Model Content

[0006] To address the issue that the cylinder piston rod needs to continuously extend its extension and retraction stroke during the tin foil sealing sheet feeding process, which increases the burden on the cylinder, shortens its lifespan, and affects feeding efficiency and quality, this application provides a feeding device for tin foil sealing sheets.

[0007] The technical solution of the feeding device for tin foil sealing sheets provided in this application is as follows: A feeding device for tin foil sealing sheets includes a controller and a worktable. A placement plate for holding the tin foil sealing sheets is provided on the worktable. A suction component for picking up the tin foil sealing sheets is provided above the placement plate. A moving component for moving the suction component is provided above the worktable. The controller is electrically connected to the suction component and the moving component. A bracket is fixed below the worktable, and a nut is rotatably mounted on the bracket. A lead screw for changing the height of the tin foil sealing sheets is provided in the middle of the placement plate. The lead screw is threadedly connected to the nut and passes through the worktable, abutting against the bottom of the tin foil sealing sheet. A drive component for rotating the nut is mounted on the worktable.

[0008] By adopting the above technical solution, it was observed that when the height of the tin foil sealing sheet decreased due to continuous feeding, the operating drive component caused the nut to rotate, and the lead screw to move vertically, changing the height of the tin foil sealing sheet. This avoids the cylinder piston rod continuously extending its extension and retraction stroke during suction, reducing the cylinder load, extending its life, improving suction accuracy, and thus improving the working efficiency and quality of the feeding device.

[0009] Optionally, a mounting block is provided above the placement plate, and a position sensor for sensing the tin foil sealing sheet is provided on the mounting block. The position sensor is electrically connected to the controller. A status indicator is also provided on the worktable, and the status indicator is electrically connected to the controller.

[0010] By adopting the above technical solution, the position sensor senses the position information of the foil sealing sheet on the placement plate in real time and promptly feeds this information back to the controller. After receiving the position information, the controller issues a command. Based on the command issued by the controller, the status indicator visually displays the current height of the foil sealing sheet.

[0011] Optionally, the drive assembly includes a drive member, a driving bevel gear, and a driven bevel gear. The driving bevel gear is coaxially fixed to the output end of the drive member, and the inner wall of the driven bevel gear is coaxially fixed to the outer wall of the nut. The driven bevel gear meshes with the driving bevel gear.

[0012] By adopting the above technical solution, the driving component drives the active bevel gear to rotate, which in turn drives the driven bevel gear meshing with it to rotate, and the driven bevel gear drives the nut to rotate. Since the nut and the lead screw are threaded together, the lead screw is driven to move upward, changing the height of the tin foil sealing sheet, thereby reducing the stroke of the cylinder piston rod.

[0013] Optionally, the driving component is a servo motor, which is electrically connected to the controller.

[0014] By adopting the above technical solution, the position sensor sends a signal to the controller. On the one hand, the controller controls the status indicator device, and on the other hand, the controller controls the servo motor to work, driving the lead screw to move upward to change the height of the tin foil sealing sheet and reduce the stroke of the cylinder piston rod.

[0015] Optionally, the placement plate is fixed with a plurality of limiting posts for limiting the position of the circular piece edge, the plurality of limiting posts are arranged in a circle, and the mounting block is disposed on the plurality of limiting posts.

[0016] By adopting the above technical solution, multiple circumferentially arranged limiting posts can effectively restrict the edge position of the circular piece, prevent the circular piece from shifting or sliding on the placement plate, and ensure the positional accuracy of the circular piece in the subsequent feeding process.

[0017] Optionally, the placement plate is further fixed with a limiting component for restricting the placement position of the connecting piece. The limiting component includes a first vertical plate and a second vertical plate. The first vertical plate and the second vertical plate are arranged in parallel and are both fixed on the placement plate. The first vertical plate and the second vertical plate form a limiting space for limiting the connecting piece.

[0018] By adopting the above technical solution, the limiting component forms a limiting space through the first vertical plate and the second vertical plate, which is used to limit the placement position of the tin foil sealing sheet connecting piece, ensure the stability and accuracy of the tin foil sealing sheet placement, and further improve the working quality of the feeding device.

[0019] Optionally, an arc-shaped plate is fixed between the first vertical plate and the second vertical plate, the arc-shaped plate being used to limit the arc-shaped edge of the connecting piece.

[0020] By adopting the above technical solution, the arc plate can closely fit the arc edge of the connecting piece, which can play a more precise limiting role for the connecting piece and effectively prevent the connecting piece from rotating or shifting during placement. This further improves the stability of the connecting piece placement and ensures that the feeding device can operate more reliably.

[0021] Optionally, the suction assembly includes a vacuum pump, a connecting plate, and a suction nozzle. The vacuum pump is mounted on the worktable, the connecting plate is fixed to the moving assembly, the suction nozzle is fixed to the connecting plate, the suction nozzle is connected to the vacuum pump via a pipe, and the vacuum pump is electrically connected to the controller.

[0022] By adopting the above technical solution, the suction component generates negative pressure through a vacuum pump and uses a suction nozzle to suck up the tin foil sealing sheet. The connecting plate serves to fix the suction nozzle, enabling the suction component to move accurately to the designated position for suction operation under the drive of the moving component.

[0023] Optionally, the moving component includes a mounting bracket, a first cylinder, and a second cylinder. The mounting bracket is fixed on the worktable, the first cylinder slides on the mounting bracket, the second cylinder is fixed on the mounting bracket, and the piston rod of the second cylinder is fixed on the cylinder body of the first cylinder. The piston rod of the first cylinder is fixed to the connecting plate.

[0024] By adopting the above technical solution, the first cylinder moves the suction component up and down, and the second cylinder moves the suction component left and right. After suctioning the tin foil sealing sheet, the suction component can accurately move the tin foil sealing sheet to the designated position according to the feeding requirements.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. The position sensor detects the position of the tin foil sealing sheet and sends the signal to the controller. After receiving the signal, the controller controls the status indicator device to help the operator understand the feeding situation. On the other hand, it controls the servo motor to drive the lead screw to move upward to change the height of the tin foil sealing sheet and reduce the stroke of the cylinder piston rod.

[0026] 2. By setting limiting posts and limiting components on the placement plate, the position of the circular piece of tin foil sealing sheet and the connecting piece can be restricted, making it easier for the suction component to accurately pick up the foil. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses a feeding device for tin foil sealing sheets.

[0032] A transport platform is provided on one side of this device, which continuously transports the workpieces combined with the foil sealing sheets. This device is used to pick up the neatly stacked foil sealing sheets one by one and accurately place them into the corresponding positions on the workpieces on the transport platform, facilitating the next process of combining the workpieces and foil sealing sheets.

[0033] Reference Figure 2 A feeding device for tin foil sealing sheets includes a controller 1 and a worktable 2. A hollow placement plate 3 is provided on the worktable 2 for holding neatly stacked tin foil sealing sheets. A suction assembly 4 is positioned directly above the placement plate 3, and the suction assembly 4 is used to pick up the tin foil sealing sheets located on the placement plate 3 one by one. A moving assembly 5 is also installed on the worktable 2, and the suction assembly 4 is fixed to the moving assembly 5. The moving assembly 5 drives the suction assembly 4 to move, thereby transporting the tin foil sealing sheets picked up by the suction assembly 4 to a designated position and accurately placing them on a workpiece located on a transport platform.

[0034] Reference Figure 2 Above the placement plate 3, a mounting block 10 is also provided. The mounting block 10 has a position sensor 11 for sensing the position of the tin foil sealing sheet. The position sensor 11 is electrically connected to the controller 1. In this embodiment, the position sensor 11 is a proximity switch.

[0035] Reference Figure 2 A status indicator 12 is also provided on the workbench 2, and the status indicator 12 is electrically connected to the controller 1. The proximity switch senses the position information of the tin foil sealing sheet on the placement plate 3 in real time and promptly feeds it back to the controller 1. After receiving the position information, the controller 1 issues a command, and the status indicator 12 displays the current height of the tin foil sealing sheet intuitively according to the command.

[0036] Reference Figure 2 During the feeding process, as the suction component 4 continuously picks up the tin foil sealing sheet located on the placement plate 3, the overall height of the tin foil sealing sheet continuously decreases. In this embodiment, when the proximity switch senses the tin foil sealing sheet at the top, the proximity switch sends a signal to the controller 1. Upon receiving the signal, the controller 1 emits a green light from the control status indicator 12. When the proximity switch does not sense the tin foil sealing sheet at the top, the proximity switch sends a signal to the controller 1. Upon receiving the signal, the controller 1 emits a red light from the control status indicator 12.

[0037] Reference Figure 2 and Figure 3A lead screw 8 is installed in the middle of the placement plate 3, and the top end of the lead screw 8 passes through the middle of the worktable 2 and the placement plate 3 and abuts against the tin foil sealing sheet. A bracket 6 is fixed to the bottom of the worktable 2, and a nut 7 is rotatably mounted on the bracket 6, with the nut 7 threadedly connected to the lead screw 8. A drive assembly 9 for driving the nut 7 to rotate is also installed at the bottom of the worktable 2. When the drive assembly 9 drives the nut 7 to rotate, the lead screw 8 will move linearly along the axial direction.

[0038] Reference Figure 2 and Figure 3 When the proximity switch fails to detect the top foil sealing piece, it sends a signal to controller 1. Upon receiving this signal, controller 1 controls drive assembly 9 to rotate nut 7 to raise screw 8, adjusting the height of the foil sealing piece. The proximity switch continues to operate until it detects the top foil sealing piece again, at which point it sends a signal to controller 1, which then stops drive assembly 9.

[0039] This device maintains the height of the tin foil sealing sheet at a suitable position for the suction component 4, ensuring the stability and accuracy of the suction process and improving feeding efficiency. Furthermore, it avoids the problem of the cylinder piston rod continuously extending its extension and retraction stroke in traditional methods, further improving feeding efficiency and quality.

[0040] Reference Figure 3 The drive assembly 9 includes a drive member, a drive bevel gear 92 and a driven bevel gear 93. The drive bevel gear 92 is coaxially fixed to the output end of the drive member. The inner wall of the driven bevel gear 93 is coaxially fixed to the outer wall of the nut 7. The driven bevel gear 93 meshes with the drive bevel gear 92.

[0041] The driving component is a servo motor 91, which has precise control performance. When the driving component rotates, it drives the driving bevel gear 92 to rotate, and the driving bevel gear 92 drives the driven bevel gear 93 to rotate through meshing, thereby causing the nut 7 to rotate.

[0042] Reference Figure 2 and Figure 4 The suction assembly 4 includes a vacuum pump 41, a connecting plate 42, and a suction nozzle 43. The vacuum pump 41 is mounted on the worktable 2, the connecting plate 42 is fixed to the moving assembly 5, and the suction nozzle 43 is fixed to the connecting plate 42. The suction nozzle 43 is connected to the vacuum pump 41 via a pipe. In this embodiment, the suction nozzle 43 is made of rubber, which has good adsorption performance. The vacuum pump 41 is electrically connected to the controller 1, which can control the opening and closing of the vacuum pump 41.

[0043] Reference Figure 2 and Figure 4When it is necessary to pick up the tin foil sealing sheet, the controller 1 controls the vacuum pump 41 to start. The vacuum pump 41 generates negative pressure, which is transmitted to the suction nozzle 43 through the pipeline. The suction nozzle 43 uses the negative pressure to firmly adhere the tin foil sealing sheet. After the picking is completed, the moving component 5 moves the connecting plate 42 and the suction nozzle 43 to the designated position. At this time, the controller 1 controls the vacuum pump 41 to turn off, the negative pressure disappears, and the tin foil sealing sheet is placed in the corresponding position, completing the picking and placement actions in the feeding process.

[0044] In addition, the rubber nozzle 43 will not damage the surface of the foil sealing sheet when it comes into contact with it, and will not cause the foil sealing sheet to bend, thus ensuring the quality of the foil sealing sheet.

[0045] Reference Figure 2 and Figure 4 The moving component 5 includes a mounting frame 51, a first cylinder 52, and a second cylinder 53. The mounting frame 51 is mounted on the workbench 2 and serves as the supporting foundation for the entire moving component 5. A protective cover 18 is installed on the mounting frame 51. Both the first cylinder 52 and the second cylinder 53 are located inside the protective cover 18, which protects them from external environmental interference and damage.

[0046] Reference Figure 2 and Figure 4 The first cylinder 52 slides on the mounting bracket 51, and the second cylinder 53 is fixed on the mounting bracket 51, with the cylinder body of the first cylinder 52 fixed to the piston rod of the second cylinder 53. The first cylinder 52 and the second cylinder 53 are connected to an external air source through pipes, and the first cylinder 52 and the second cylinder 53 are also electrically connected to the controller 1.

[0047] Controller 1 controls the piston rod of the first cylinder 52 to extend or retract, thereby moving the suction nozzle 43 up and down to a suitable position to facilitate the suction of a single tin foil sealing sheet. Controller 1 controls the piston rod of the second cylinder 53 to extend or retract, thereby moving the first cylinder 52 accordingly to transport the suctioned tin foil sealing sheet to a designated position.

[0048] Reference Figure 1 , Figure 2 and Figure 5 Multiple limiting posts 13 are fixed on the placement plate 3 to limit the position of the edge of the circular piece 16, and the multiple limiting posts 13 are arranged in a circle. The function of the limiting posts 13 is to prevent the circular piece 16 of the tin foil sealing sheet from shifting during placement, and to ensure that the suction assembly 4 can accurately pick it up.

[0049] Reference Figure 1 and Figure 5A limiting component 14 for limiting the placement position of the connecting piece 17 is also fixed on the placement plate 3. The limiting component 14 includes a first vertical plate 141 and a second vertical plate 142. The first vertical plate 141 and the second vertical plate 142 are arranged in parallel and are both fixed on the placement plate 3. The first vertical plate 141 and the second vertical plate 142 form a limiting space for limiting the connecting piece 17.

[0050] Reference Figure 1 and Figure 5 An arc-shaped plate 15 is fixed between the first vertical plate 141 and the second vertical plate 142. The arc-shaped plate 15 is used to limit the arc-shaped edge of the connecting piece 17, and the arc-shaped plate 15 further improves the limiting effect on the connecting piece 17.

[0051] Reference Figures 4 to 6 A circular groove 19, matching the cross-sectional dimensions of the limiting post 13, is formed at the bottom of the mounting block 10, allowing the mounting block 10 to be stably placed on multiple limiting posts 13 without easily falling off. A cavity 20 is formed in the middle of the mounting block 10, and the cavity 20 matches the size of the tin foil sealing sheet. The suction nozzle 43 passes through the cavity 20 of the mounting block 10 and then picks up the tin foil sealing sheet on the placement plate 3.

[0052] The implementation principle of the feeding device for tin foil sealing sheets according to this application embodiment is as follows: the position sensor 11 senses the position of the tin foil sealing sheet in real time and transmits the signal to the controller 1. The controller 1 controls the operation of the drive component 9 according to the received signal, causing the lead screw 8 to rise or stop, thereby adjusting the height of the tin foil sealing sheet. This device keeps the height of the tin foil sealing sheet at a suitable height for the suction component 4 to pick up, ensuring the stability and accuracy of the suction process and improving the feeding efficiency. In addition, this also avoids the problem of the cylinder piston rod continuously lengthening its extension and retraction stroke in the traditional method, improving the feeding efficiency and quality.
