Description

Technical Field

[0001] This utility model relates to the field of equipment technology in the 3C industry, and more specifically, it relates to a small protective iron sheet flipping device. Background Technology

[0002] Coiling iron sheets are used in the assembly process of communication and consumer electronics products in the 3C industry. Coiling iron sheets are small protective iron sheets that are often used to protect flexible circuits.

[0003] Currently, the Cowling sheet is placed on the extraction tray during assembly. The mechanical equipment can only assemble the Cowling sheet according to its fixed placement surface during the bonding and assembly process. When it is necessary to assemble the sheet from the reverse side, the Cowling sheet needs to be manually flipped. This leads to chaos in the entire bonding process, reduces production efficiency, and increases labor costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a small protective iron sheet flipping device that uses a machine to replace manual labor, thereby automatically flipping small protective iron sheets, reducing labor costs, and improving production efficiency.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0006] A small protective iron sheet flipping device includes a support frame, a receiving platform for receiving small protective iron sheets on the support frame, a lifting cylinder on the side wall of the support frame, a connecting seat on the telescopic rod of the lifting cylinder, a negative pressure adsorption platform for absorbing small protective iron sheets located on the receiving platform and a flipping component for driving the negative pressure adsorption platform to flip 180 degrees on the connecting seat; the flipping component is drivenly connected to the negative pressure adsorption platform.

[0007] Optionally, the negative pressure adsorption platform includes a rotating shaft with a gear in the middle and an adsorption block at the end for connecting to a negative pressure device. The adsorption block is covered with urethane rubber blocks, and the urethane rubber blocks have several suction holes for adsorbing small protective iron sheets. The rotating shaft is rotatably connected to the connecting seat.

[0008] Optionally, the tilting assembly includes a side-push cylinder, a rack for mating with the gear, and a connecting plate; one end of the connecting plate is fixedly connected to the rack, and the other end is fixedly connected to the telescopic rod of the side-push cylinder; the cylinder seat of the side-push cylinder is fixedly connected to the connecting seat, and the rack meshes with the gear.

[0009] Optionally, a limiting block is provided on the end of the rotating shaft opposite to the adsorption block, and two limiting columns are provided on the connecting seat to be adapted to the limiting block, one of the limiting columns being located on one side of the rotating shaft and the other limiting column being located on the other side of the rotating shaft.

[0010] Optionally, the top of the limiting column is equipped with a soft rubber pad to reduce noise.

[0011] Optionally, the rack is slidably connected to the connecting seat via a linear guide assembly.

[0012] In summary, the above embodiments of this utility model have the following beneficial effects: Firstly, the utility model receives small protective iron sheets from the robotic arm via a receiving platform. After the robotic arm moves away, a lifting cylinder lifts the connecting seat, negative pressure adsorption platform, and flipping assembly. After lifting, the flipping assembly drives the negative pressure adsorption platform to flip 180°. Then, under the action of a vacuum device, the negative pressure adsorption platform sucks up the small protective iron sheet located on the receiving platform. The flipping assembly then reverses its action, driving the negative pressure adsorption platform to flip 180° back to its original position. The lifting cylinder then descends back to its original position. Subsequently, the robotic arm moves from its waiting position to above the negative pressure adsorption platform to pick up the small protective iron sheet and moves it to the assembly station, thus completing one round of flipping of the small protective iron sheet. This design effectively reduces labor costs, mechanizes tedious manual operations, and greatly improves production efficiency. Attached Figure Description

[0019] To make the objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Several embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] This utility model provides a small protective iron sheet flipping device, such as Figure 1-6 As shown, it includes a support frame 1, a receiving platform 2 for receiving small protective iron pieces 7 on the support frame 1, a lifting cylinder 3 on the side wall of the support frame 1, a connecting seat 4 on the telescopic rod of the lifting cylinder 3, a negative pressure adsorption platform 5 for picking up the small protective iron pieces 7 located on the receiving platform 2 and a flipping component 6 for driving the negative pressure adsorption platform 5 to flip 180 degrees on the connecting seat 4; the flipping component 6 is connected to the negative pressure adsorption platform 5 in a transmission connection.

[0023] Specifically, the receiving platform 2 is fixedly mounted on the top of the support frame 1 with screws. The receiving platform 2 has several suction holes for firmly adsorbing small protective iron pieces 7. The suction holes are connected to negative pressure devices such as vacuum pumps through conduits. The cylinder seat of the lifting cylinder 3 is mounted on the side of the support frame 1 with screws, opposite to the receiving platform 2. A connecting seat 4 is fixedly mounted on the telescopic rod of the lifting cylinder 3 with screws. The connecting seat 4 provides an installation position for the negative pressure adsorption platform 5 and the flipping assembly 6. The negative pressure adsorption platform 5 is rotatably mounted on the connecting seat 4 through bearings, and the flipping assembly 6 is fixedly mounted on the connecting seat 4 with screws. The drive end of the flipping assembly 6 is driven by gear meshing with the negative pressure adsorption platform 5, which is used to drive the negative pressure adsorption platform 5 to rotate 180 degrees as needed.

[0024] This invention first receives a small protective iron sheet 7 from a robotic arm via a receiving platform 2. After the robotic arm moves away, a lifting cylinder 3 lifts the connecting seat 4, the negative pressure adsorption platform 5, and the flipping assembly 6. After lifting, the flipping assembly 6 drives the negative pressure adsorption platform 5 to flip 180°. Then, under the action of a vacuum device, the negative pressure adsorption platform 5 sucks up the small protective iron sheet 7 located on the receiving platform 2. The flipping assembly 6 then reverses its action, driving the negative pressure adsorption platform 5 to flip 180° back to its original position. The lifting cylinder 3 then descends back to its original position. Subsequently, the robotic arm moves from its waiting position to above the negative pressure adsorption platform 5 to pick up the small protective iron sheet 7 and moves it to the assembly station, thus completing one round of flipping of the small protective iron sheet 7. This design effectively reduces labor costs, mechanizes tedious manual operations, and greatly improves production efficiency.

[0025] Furthermore, the negative pressure adsorption platform 5 includes a rotating shaft 51, a gear 52 is provided in the middle of the rotating shaft 51, and an adsorption block 53 for communicating with the negative pressure device is provided at the end of the rotating shaft 51. An urethane block 54 is provided on the adsorption block 53, and several suction holes 541 for adsorbing small protective iron sheets 7 are opened on the urethane block 54; the rotating shaft 51 is rotatably connected to the connecting seat 4.

[0026] like Figure 1 and Figure 3 As shown, the rotating shaft 51 and gear 52 are integrally formed. The gear 52 is located in the middle of the rotating shaft 51. The inner rings of the bearings are tightly nested at both ends of the rotating shaft 51, and the outer rings of the bearings are tightly nested on the connecting seat 4. The adsorption block 53 is L-shaped and is fixed to the end of the rotating shaft 51 near the receiving platform 2 by screws. The adsorption block 53 has a negative pressure passage inside, which is connected to an external negative pressure device (such as a vacuum pump) through an air pipe. The urethane block 54 is fixed to the adsorption block 53 by double-sided tape or screws. Its position is adjusted according to the layout of the small protective iron sheet 7. The air suction hole 541 inside the urethane block 54 is connected to the negative pressure passage on the adsorption block 53. The urethane block 54 is relatively soft, which can increase the contact area with the small protective iron sheet 7, improve the sealing performance, and ensure that the small protective iron sheet 7 will not be flung away during the flipping process.

[0027] Furthermore, the flipping assembly 6 includes a side-push cylinder 61, a rack 62 adapted to the gear 52, and a connecting piece 63; one end of the connecting piece 63 is fixedly connected to the rack 62, and the other end is fixedly connected to the telescopic rod of the side-push cylinder 61; the cylinder seat of the side-push cylinder 61 is fixedly connected to the connecting seat 4, and the rack 62 is meshed with the gear 52.

[0028] like Figure 1-4As shown, the side-push cylinder 61 is fixedly mounted on the connecting seat 4 with screws. Its extension rod is fixedly connected to the lower end of the connecting plate 63 with screws. The upper end of the connecting plate 63 is fixedly connected to the end of the rack 62 with screws. The rack 62 is located below the gear 52 and passes through the connecting seat 4. The top of the rack 62 meshes with the gear 52, and its bottom may or may not be in contact with the connecting seat 4. Figure 1 As shown, when the telescopic rod of the side-push cylinder 61 retracts, the rack 62 drives the gear 52 to rotate 180 degrees, which in turn drives the adsorption block 53 to rotate 180 degrees above the receiving platform 2 to adsorb the small protective iron sheet 7. After adsorption is completed, the telescopic rod of the side-push cylinder 61 extends outward, driving the adsorption block 53 to rotate 180 degrees in the opposite direction to return to its original position. Compared with directly using a servo motor as the flipping component 6, the flipping component 6 composed of the side-push cylinder 61 and the connecting piece 63 has the advantages of low cost and high flipping stability.

[0029] Furthermore, a limiting block 55 is provided on the end of the rotating shaft 51 opposite to the adsorption block 53, and two limiting columns 41 are provided on the connecting seat 4 for matching the limiting block 55. One limiting column 41 is located on one side of the rotating shaft 51, and the other limiting column 41 is located on the other side of the rotating shaft 51.

[0030] like Figure 2-5 As shown, the limiting block 55 is fixedly installed on the end of the rotating shaft 51 away from the adsorption block 53 by screws, and the limiting column 41 is screwed onto the connecting seat 4 by threaded connection. The two limiting columns 41 are located on one side and the other side of the rotating shaft 51 respectively, which can ensure that the rotating shaft 51 rotates at an angle of 180 degrees and is not limited by the excessive extension and retraction stroke of the side push cylinder 61.

[0031] Furthermore, in order to reduce the noise or vibration generated when the limiting block 55 quickly presses against the limiting post 41, a soft rubber pad is attached to the top of the limiting block 55 (not shown in the attached diagram).

[0032] Furthermore, to make the entire flipping process smoother and more stable, a conventional linear slide rail assembly (not shown in the attached figure) is added between the rack 62 and the connecting seat 4. Specifically, the bottom of the rack 62 is fixedly connected to the slider in the linear slide rail assembly by screws, and the connecting seat 4 is fixedly connected to the slide rail in the linear slide rail assembly by screws.

[0033] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
