Description

Technical Field

[0001] This utility model belongs to the field of mechanical manufacturing technology, and in particular relates to a sheet-like object flipping and multi-angle handling device. Background Technology

[0002] Sheet-like materials, such as PCBs, paper, and boards, generally have a flat physical characteristic. When double-sided processing is required for these products, a flipping operation is usually necessary to complete the reverse side processing. Currently, traditional production methods mainly rely on manual flipping, which is not only inefficient and labor-intensive, but also carries the risk of scratching the surface of the sheet-like materials and damaging the edges due to improper operation. This is especially true for high-precision components such as PCBs, where manual intervention can easily affect their positioning accuracy and product quality.

[0003] To address the drawbacks of manual flipping, some automated flipping devices have emerged in the prior art. For example, Chinese patent CN218217847U discloses a PCB board flipping device, which can automatically receive and flip PCB boards by setting a flipping component with a receiving groove. Specifically, the PCB board enters the receiving groove through an opening at one end of the flipping component, and its position is restricted by clamps on both sides of the groove. However, this solution still has significant drawbacks in practical applications: First, after entering the receiving groove, the PCB board needs to slide along the clamps for a certain distance to achieve positioning. During this process, the surface of the board continuously rubs against the clamps, which can easily lead to wear on the surface circuitry or coating of the PCB board, affecting its quality and accuracy. Second, since the flipping component is only open at one end, it can only rotate a maximum of 180° in the upward direction of the opening during the flipping operation. If reverse rotation occurs due to operational errors or system errors, the PCB board in the receiving groove is very likely to fall out, causing product damage or production interruption. The safety and reliability of the equipment still need to be improved.

[0004] Therefore, there is an urgent need for a new type of sheet-like flipping device that can achieve automated flipping while effectively avoiding wear on the workpiece surface and preventing accidental detachment, thereby improving the stability of the flipping operation and the processing quality.

[0005] Furthermore, existing sheet material handling systems are mostly only suitable for switching between two workstations. When processing sheet materials requires switching between more than two workstations, they can only be used when multiple workstations are set up in parallel or perpendicular positions. When multiple workstations are set at arbitrary angles, sheet materials cannot be directly transferred from one workstation to the next. Therefore, existing automated handling devices have certain limitations and require further improvement. Utility Model Content

[0021] This utility model discloses a sheet-like material flipping device, installed on a worktable 9. The sheet-like material flipping device includes as follows: Figures 1 to 3 The rotating mechanism 1 and clamping mechanism 2 shown herein drive the clamping mechanism 2 and the sheet-like object it clamps to rotate via the rotating mechanism 1. Preferably, the rotation is 180°, that is, the rotating mechanism 1 realizes the automated flipping operation of the sheet-like object.

[0022] Specifically, such as Figure 1The workbench 9 is vertically equipped with a rotating mechanism mounting plate 90 and symmetrically arranged support seats 91. The rotating mechanism 1 includes a rotating cylinder 11 and a rotating shaft 12. Further, the output end of the rotating cylinder 11 is connected to the rotating shaft 12 via a coupling. Furthermore, the rotating cylinder 11 is fixed to the rotating mechanism mounting plate 90. The rotating shaft 12 passes through the rotating mechanism mounting plate 90 and the support seats 91, and is fixedly connected to the clamping mechanism 2; activating the rotating cylinder 11 drives the clamping mechanism 2 to rotate synchronously.

[0023] To reduce the friction between the support base 91 and the rotating shaft 12 during rotation, this invention preferably includes a rotary bearing 911 within the support base 91, with the rotating shaft 12 passing through the rotary bearing 911. Further, as... Figure 1 and Figure 2 As shown, a hollow base 210 is provided on the inner side of the support 91, and the base 210 is fixedly connected to the output end of the rotating shaft 12. A base mounting plate 120 is fixed to the end of the rotating shaft 12, and the inner wall of the base mounting plate 120 is connected to the base 210. Furthermore, in this invention, it is preferable to design the height of the support 91 to be greater than half the width of the base 210, so that the platform 9 will not interfere with it during rotation, ensuring smooth rotation. like Figures 1 to 2 As shown, the clamping mechanism 2 includes at least a drive source 21, a set of parallel sliding members 22, and a set of opposing clamping bars 23. The drive source 21 and the sliding members 22 are both mounted on the base 210, and the two output ends of the drive source 21 are respectively connected to a slider group 222, driving the two slider groups 222 to move towards or away from each other. The outer end face of the slider group 222 is fixedly connected to the clamping bars 23, and both are used to define the placement position of the sheet-like object.

[0024] Specifically, such as Figure 1 or Figure 3 As shown, the drive source 21 is centrally located along the width direction of the base 210. The output end of the drive source 21 has two... Figure 1 The guide grooves shown are equipped with movable blocks, and each movable block has a connecting plate 211 fixed to its outer end. The connecting plate 211 is connected to the slider assembly 222. Activating the drive source 21 causes the movable blocks and connecting plates 211 to move towards or relative to each other, thereby moving the slider assembly 222.

[0025] Furthermore, such as Figure 2As shown, the sliding member 22 includes a set of guide rails 221 fixed to the base 210, and the guide rails 221 are located at both ends of the hollow portion of the base 210. Preferably, this invention features two parallel guide rails, and each guide rail 221 has two sliders, with a first slider fixed to each slider. The end of the first slider is connected to the clamping strip 23. The sliders and the first sliders form the slider group 222.

[0026] like Figure 1 and Figure 2 As shown, a clamping groove 230 is centrally located on the inner side of the clamping strip 23 along its height direction. The clamping strip 23 is preferably made of a plastic material with certain strength, or a similar material such as silicone; no specific limitation is made here. When the sheet-like object is placed in the clamping groove 230, the two mutually restrain each other, ensuring the stability of the sheet-like object and effectively avoiding the risk of it falling off during flipping, thus improving processing quality. Furthermore, since the clamping strip 23 is fixedly connected to the first slider, activating the drive source 21 causes the two clamping strips 23 to move towards or relative to each other, adjusting the distance between the two clamping strips 23 to meet the clamping requirements of sheet-like objects of different widths. Further, the clamping strip 23 is also provided with a set of clearance grooves 231 to allow the suction nozzle to adsorb or place the sheet-like object.

[0027] This utility model also discloses, as follows: Figures 4 to 8 The illustrated multi-angle conveying device for sheet-like materials includes any of the sheet-like material flipping devices described above, and further includes a robotic arm 3, a sheet-like material loading mechanism 4, and a sheet-like material unloading mechanism 5. The robotic arm 3 is positioned as follows: Figure 4 and Figure 5 On the mechanical platform 30 shown, the robotic arm 3 switches between the sheet material feeding mechanism 4, the worktable 9 and the sheet material unloading mechanism 5, and sequentially transports the sheet material placed on the sheet material feeding mechanism 4 to the worktable 9 for flipping, and then transports the flipped sheet material to the sheet material unloading mechanism 5 for unloading.

[0028] The rotating arm of the robotic arm 3 can be driven to rotate relative to the mechanical platform 30, and the end of the rotating arm of the robotic arm 3 is provided with a lifting mechanism 31 and a fine-tuning mechanism 32. The lifting mechanism 31 switches the adsorbed sheet material to different workstations for processing; the fine-tuning mechanism 32 adjusts the placement angle of the sheet material according to the requirements of the processing workstation.

[0029] Specifically, the lifting mechanism 31 is a known structure with linear movement function, such as a cylinder or electric cylinder. Its output end is provided with a connector for adsorbing, clamping, or connecting a sheet-like carrier plate to drive the sheet-like object to move in the height direction. The fine-tuning mechanism 32 is a rotating shaft, which is driven to rotate by a rotary cylinder or motor. The lifting mechanism 31 is fixed on the rotating shaft and driven to rotate by the rotating shaft. Furthermore, the rotating shaft is a stepless rotating shaft, that is, its rotation angle is between 0° and 360°, which can meet the rotation requirements of any angle. Therefore, the robot arm 3 can transport the sheet-like object between different workstations and adjust the angle of the sheet-like object at the start and end positions of the transport to meet the placement requirements of different workstations and improve the flexibility of use.

[0030] A multi-angle conveying device for sheet materials also includes a sheet material feeding mechanism 4. Specifically, as shown... Figure 6 As shown, the sheet material feeding mechanism 4 includes a lifting component 41, a transfer component 42, and a positioning component 43. The positioning component 43 is disposed on the lifting component 41 and the transfer component 42, and both the positioning component 43 and the transfer component 42 are driven by the lifting component 41 to move along the height direction to match the feeding and conveying requirements of the previous process.

[0031] Furthermore, such as Figure 7 The lifting assembly 41 shown in the figure includes a motor 411, a guide column 412, a lead screw 413, and a support frame 414 connected to the lead screw 413. The transfer assembly 42 is a conveyor belt mounted on the support frame 414. Since the structure of the conveyor belt is a known structure, it will not be described in detail here. The positioning assembly 43 includes a first sensor 431, a second sensor 432 mounted on the support frame 414, and a third sensor 433 mounted on the transfer assembly 42. The first sensor 431 and the second sensor 432 are both fiber optic sensors. The first sensor 431 is used to detect whether there is a sheet-like carrier plate on the conveyor line; the second sensor 432 is used to detect whether there is a sheet-like object to be processed on the sheet-like carrier plate. The third sensor 433 is a proximity sensor, which is matched with the sensing device on the sheet-like carrier plate to detect whether the sheet-like carrier plate has been transferred to the correct position, thereby controlling the start and stop of the transfer assembly 42. In addition, the support frame 414 is also equipped with a buffer to reduce the force on the end face of the sheet-like material after it is in place, while reducing the vibration of the sheet-like material, improving the stability of the movement process, and ensuring the integrity of the sheet-like material.

[0032] A multi-angle conveying device for sheet materials also includes a sheet material unloading mechanism 5. The sheet material unloading mechanism 5 includes an unloading conveyor line that outputs the processed sheet material.

[0033] This utility model has many other embodiments. All technical solutions formed by equivalent transformation or equivalent transformation fall within the protection scope of this utility model.
