Description
Technical Field
[0001] This utility model relates to the field of laser cutting silicon wafer technology, and in particular to an integrated device for the safe transfer and stacking of large-sized, fragile thin wafers. Background Technology
[0002] In the machining process, various types of thin sheets are often required. Taking laser-cut silicon wafers as an example, after the silicon wafers become finished products, they need to be transferred to facilitate the smooth progress of subsequent testing and stacking processes.
[0003] In existing technologies, the transfer and handling of silicon wafers is mostly carried out by workers using multiple workpieces or devices. This involves a large number of devices, occupies a significant amount of workspace, and is inefficient, requiring positional calibration for each step. Generally, a stacker crane is needed for transfer, but existing stacker cranes can only perform forward / backward and up / down movements. Often, additional structures are needed to remove materials during use, which increases the integration difficulty of the entire machine system and results in efficiency far below expectations. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide an integrated device for the safe transfer and stacking of large-sized fragile thin sheets, which is used to solve the problems of high cost, complicated device, large space occupation and low efficiency of existing large-sized fragile thin sheet transfer and processing.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an integrated device for safe transfer and stacking of large-sized fragile thin sheets, including a steering wheel, a bevel gear steering box, a motor 1, a wheel frame, an axle coupling, a motor 2, a stacker, a lifting frame, an annular module, a double-rib base, a shaft end sleeve, a rotating shaft, a rolling bearing, a bearing cover, an open sleeve, a lifting base, a cylinder, a rocker arm 1, a pin, a rocker arm 2, a cylinder 2, a support seat, a retracting rod, a reducer, a motor 3, a vacuum suction cup, and a linear module. The steering wheel, bevel gear steering box, motor 1, and motor 2 are mounted and fixed on the wheel frame. One end of the axle coupling is connected to motor 2, and the other end of the axle coupling is connected to the two rear steering wheels. This device uses an annular module for rotation. The annular module is mounted on the lifting frame, and the double-rib base is mounted and fixed on the annular module.
[0006] Furthermore, a rotating shaft is mounted on the double-ribbed base and positioned via rolling bearings. A speed reducer is connected to the left end of the rotating shaft, and a three-phase motor is connected to the left end of the speed reducer. The rolling bearings are axially positioned by shaft end sleeves and bearing covers at both ends. A take-up / release rod is mounted on the rotating shaft and axially positioned via an open sleeve, with circumferential positioning achieved through a spline connection. A linear module is fixedly mounted on the take-up / release rod, and a vacuum suction cup is mounted on the linear module.
[0007] Furthermore, the support is mounted and fixed on the double-ribbed base.
[0008] Compared with the prior art, the beneficial effects of this utility model are:
[0009] 1. This utility model can improve the transfer efficiency of the stacking device, is suitable for the transfer of large-sized fragile thin sheets, saves production costs, and is more conducive to the integration of cutting equipment. The loading platform of the stacking device can be retracted and extended in two stages, further reducing the demand for workspace. It also allows the stacking device to move laterally and turn, realizing multi-station operation. The device has a simple structure, low component maintenance costs, and good market prospects.
[0010] 2. This utility model firstly involves the stacking columns of the stacker crane at the rear. The material's position is calibrated by the forward and upward movement of the stacking columns. After the material's position is calibrated, the servo motor on the loading platform starts driving the rotating shaft to rotate. The take-up / release rod and vacuum suction cup connected to the rotating shaft are lowered. Simultaneously, the linear module on the take-up / release rod starts working, and the vacuum suction cup fixed to the linear module performs a second lowering. When the take-up / release rod is lowered to parallel with the material surface, the servo motor stops working, and the vacuum suction cup's lowering is completed in one operation. When the linear module on the take-up / release rod slides to directly above the material, the linear module stops working. After the vacuum suction cup is lowered a second time, there is still a certain longitudinal distance between the vacuum suction cup and the material. The stacker crane's lifting frame is slightly adjusted to bring the vacuum suction cup close to the upper surface of the material. After adjustment, the vacuum suction cup begins to work, adsorbing the material. After adsorption, the stacker crane's lifting frame slides upward a distance. Once it reaches a relatively safe position, the ring module installed on the lifting frame begins to work, driving the entire loading platform and material to rotate horizontally. When the horizontal rotation reaches 180°, the ring module stops working, and the stacker crane moves backward. After reaching the material stacking area, the stacker crane's lifting frame begins to... Position calibration is performed to ensure the material is directly above and almost flush with the material storage bin. The vacuum suction cups release their grip, allowing the material to rest on the bin. However, some fragile, thin material storage bins may not be parallel to the horizontal plane but rather at an angle. In this case, the rotating shaft on the loading platform, driven by a servo motor, rotates at the corresponding angle to align the material with the bin. After the position calibration, the vacuum suction cups release their grip, completing the material transfer. This process is repeated. After the material transfer is complete, if other materials are at other workstations, the wheel assembly installed at the bottom of the stacker crane... It can operate, and with the coordinated work of the rear drive wheel and the front steering wheel, the stacker crane can reach the work station of other materials to continue working. After the work is completed, the ring module works and drives the loading platform to rotate back to the initial position. The servo motor starts to drive the rotating shaft to rotate. The retraction rod completes one retraction and extension of the vacuum suction cup under the rotation of the rotating shaft. After one retraction is completed, the linear module installed on the retraction rod starts to work and drives the vacuum suction cup back to complete the second retraction and extension. The support base supports the vacuum suction cup and protects it from the bending moment generated when the vacuum suction cup is placed on the side, thereby increasing the load on the rotating shaft, retraction rod and other related components.
[0011] 3. The wheel assembly of this utility model can be fixed to the stacker crane with bolts. The two rear wheels serve as the driving force and do not turn. The two front steering wheels achieve steering by connecting to the bevel gear steering box under the independent control of the servo motor. The positioning of the left rolling bearing on the double rib base of the loading platform is achieved by the shaft shoulder and the shaft end sleeve. The right bearing is positioned by the shaft end sleeve and the bearing cover. The take-up and release rod installed on the rotating shaft is axially positioned by the open sleeve. The open sleeve has a threaded hole, which can be fitted with bolts and tightened to adapt to various shaft diameters. The take-up and release rod is circumferentially positioned by the spline connection. The connection between the reducer and the rotating shaft is circumferentially positioned by the flat key. The reducer is fixed to the double rib base with bolts. The position of the reducer and the rotating shaft is fixed and does not change axially, so axial positioning is completed. Therefore, axial positioning is not required. The motor and the reducer are also circumferentially positioned by the flat key connection. The motor and the reducer are fixed to the double rib base with bolts, so axial positioning is also not required.
[0012] 4. This utility model can use a rotating shaft and a linear module to realize the secondary loading and unloading of the vacuum suction cup, reducing the space requirement when the stacking device is not working. Moreover, the loading and unloading device can also place materials at multiple angles. The previous stacking device can only achieve horizontal placement and requires the cooperation of other devices. Compared with the previous stacking device, it can improve the efficiency of transfer work, reduce the number of related parts to reduce costs, and realize multi-station operation, overcoming the disadvantage of the previous stacking device that can only work at one station. This utility model has strong adaptability and can complete the transfer of materials in various situations, especially the transfer of lightweight, large-sized thin sheets. In addition, the related parts of this utility model are relatively common and have low cost, and the maintenance cost is also low. Attached Figure Description

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0019] See attached document Figure 1-4 This embodiment includes a steering wheel 1-1 mounted on a bevel gear steering box 1-2, a bevel gear steering box 1-2 mounted and fixed on a wheel frame 1-4, a bevel gear steering box 1-2 connected to a motor (1) 1-3, a motor (1) 1-3 mounted and fixed on a wheel frame 1-4, a wheel at the rear end of the wheel assembly being a drive wheel connected to an axle coupling 1-5, an axle coupling 1-5 connected to a motor (2) 1-2, a motor (2) mounted and fixed on a wheel frame 1-4, a wheel frame 1-4 mounted and fixed on a stacker 2, a lifting frame 3 mounted and fixed with an annular module 4, a double rib base 5-1-1 fixedly mounted on a slider of the annular module 4, and a motor (3) 5-5 and a reducer 5-4 mounted and fixed on the double rib base 5-1-1 by bolts.
[0020] Rolling bearing 5-1-4 is mounted on double-ribbed base 5-1-1 and positioned by shaft end sleeve 5-1-2 and bearing end cover 5-1-5. Rotating shaft 5-1-3 is mounted on double-ribbed base 5-1-1 and has rolling bearing 5-1-4 on it. Two take-up and release rods 5-3 are mounted on rotating shaft 5-1-3. The take-up and release rods 5-3 are axially positioned by open sleeve 5-1-6 and circumferentially positioned by spline connection. A linear module 5-7 is mounted and fixed on the take-up and release rods 5-3. A vacuum suction cup 5-6 is mounted and fixed on the slider of linear module 5-7. A support seat 5-2 is fixedly mounted on double-ribbed base 5-1-1, and a rubber pad is installed on the support seat 5-2 to prevent damage to the vacuum suction cup.
[0021] Working principle: The stacking column of the stacker is at the rear end. First, the stacking column 2 moves forward and upward to calibrate the position of the material. After the position calibration of the material is completed, the motor (3) 5-5 on the loading platform starts to drive the rotating shaft 5-1-3 to rotate. The take-up and release rod 5-3 and vacuum suction cup 5-6 connected to the rotating shaft 5-1-3 will be lowered. At the same time, the linear module 5-7 on the take-up and release rod 5-3 starts to work. The vacuum suction cup 5-6 fixed on the linear module 5-7 is lowered for the second time. When the take-up and release rod 5-3 is lowered to be parallel to the material surface, the servo motor (3) 5-5 stops working. The vacuum suction cup 5-6 is lowered once. When the linear module on the take-up and release rod 5-3 slides to be directly above the material, the linear module 5-7 stops working. -6 After the second lowering is completed, there is still a certain longitudinal distance between the vacuum suction cup 5-6 and the material. The stacker crane lifting frame 3 makes slight adjustments to bring the vacuum suction cup 5-6 close to the upper surface of the material. After the adjustment, the vacuum suction cup 5-6 starts to work and adsorbs the material. After adsorption, the stacker crane lifting frame 3 slides upward a distance. After reaching a relatively safe position, the annular module 4 installed on the lifting frame 3 starts to work, driving the entire loading platform and the material to rotate horizontally. When the horizontal rotation reaches 180°, the annular module 4 stops working, and the stacker crane 2 moves backward. After reaching the material stacking area, the stacker crane lifting frame 3 begins to perform position calibration, so that the material position is directly above the material storage and almost in contact with it. The vacuum suction cup 5-6 cancels adsorption, and... The material is placed on the material storage to complete the material transfer and storage. However, some fragile and thin material storages are often not parallel to the horizontal plane, but maintain a certain angle with the horizontal plane. At this time, the rotating shaft 5-1-3 on the loading platform completes the corresponding angle rotation under the drive of the servo motor (3) 5-5, so that the material and the material storage are parallel. After the corresponding position calibration, the vacuum suction cup 5-6 cancels the adsorption, thereby completing the material transfer and storage. Repeat the above actions. After the material is stored, if other materials are on other workstations, the wheel assembly 1 installed at the lower end of the stacker can work. The mutual coordination between the drive wheel driven by the motor (2) 1-6 and the drive bevel gear steering box 1-2 driven by the motor (1) 1-3 to indirectly make the steering wheel 1-1 turn. The stacker crane 2 moves to the work station of other materials to continue working. After the work is completed, the ring module 4 works and drives the loading platform 5 to rotate back to the initial position. The servo motor (3) starts to drive the rotating shaft 5-1-3 to rotate. The retracting rod 5-3 completes the retracting of the vacuum suction cup 5-6 once under the rotation of the rotating shaft 5-1-3. After the first retracting is completed, the linear module 5-7 installed on the retracting rod 5-3 starts to work and drives the vacuum suction cup 5-6 back to complete the second retracting, so that it fits just with the support seat 5-2. The support seat 5-2 supports the vacuum suction cup 5-6 and protects the bending moment generated when the vacuum suction cup 5-6 is placed on the side, thereby increasing the load of the rotating shaft 5-1-3, the retracting rod 5-3 and other related components, thereby achieving the function of protecting the related components.
