[0036] A: Long workpiece. DETAILED DESCRIPTION

[0037] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Figure 2 The orientation is referenced.

[0038] See also Figure 1-5 A feeding device proposed in an embodiment of the present invention includes a platform, a material moving mechanism and a supporting mechanism.

[0039] The material transfer mechanism is mounted on the platform and is capable of horizontal movement relative to the platform. The support mechanism is fixed to the platform and is capable of supporting the elongated workpiece A. The material transfer mechanism includes a base 61 and a support frame 62. The support frame 62 is mounted on the base 61 and is capable of being raised and lowered relative to the base 61. The support frame 62 can be raised and lowered to a material transfer height and a release height. The material transfer height is higher than the release height.

[0040] When the support frame 62 is at the material transfer height, it can propel the elongated workpiece A away from the support mechanism. When the material transfer mechanism as a whole moves horizontally relative to the platform a set distance, the support frame 62 can drive the elongated workpiece A to move horizontally relative to the support frame 62 a set distance. When the support frame 62 is at the release height, the support frame 62 can be detached from the elongated workpiece A, and the support mechanism can support the elongated workpiece A.

[0041] During use of the present feeding device, the elongated workpiece A can be supported on the support mechanism and segmented in cooperation with the cutting mechanism. When one segmentation is completed, it is necessary to move the elongated workpiece A horizontally relative to the support mechanism by a set distance so that the next portion to be cut is moved below the cutting mechanism. The specific operation is as follows: first, the support frame 62 drives the elongated workpiece A to move upward relative to the base 61 to the material shifting height to separate the elongated workpiece A from the support mechanism, and then the material shifting mechanism as a whole moves horizontally relative to the platform to a set distance to drive the elongated workpiece A to move horizontally relative to the support mechanism by a set distance, and so that the portion to be cut of the elongated workpiece A is located below the cutting mechanism. Subsequently, the support frame 62 drives the elongated workpiece A downward relative to the base 61 to a release height so that the top of the support frame 62 can be separated from the elongated workpiece A, and the elongated workpiece A is supported on the support mechanism again, waiting for cutting and segmentation. Therefore, this material moving mechanism can drive the elongated workpiece A to move horizontally a set distance relative to the supporting mechanism when the elongated workpiece A is detached from the supporting mechanism, thereby avoiding wear between the peripheral wall of the elongated workpiece A and the supporting mechanism, and ensuring the peripheral wall accuracy of the elongated workpiece A.

[0042] Preferably, the top of the support frame 62 is a V-shaped surface, and the long workpiece A is a silicon rod. The top of the support frame 62 can support the peripheral wall of the silicon rod. Therefore, the feeding device is particularly suitable for continuous feeding of silicon rods A to achieve continuous segmentation.

[0043] Furthermore, the material moving mechanism further includes a transverse moving assembly 63 , which includes a transverse plate 631 , a wedge block 632 , a lifting platform 633 and a rolling body 634 .

[0044] A horizontal plate 631 is mounted on the base 61 so that it can move horizontally relative to the base 61. A plurality of wedge-shaped blocks 632 are spaced apart along the top of the horizontal plate 631, each with an inclined top surface. A lifting platform 633 is mounted on the base 61 so that it can be raised and lowered relative to the base 61. A plurality of rolling elements 634 are spaced apart along the length of the lifting platform 633, each corresponding to and rolling in engagement with the plurality of wedge-shaped blocks 632. The lifting platform 633 is fixedly connected to the support frame 62.

[0045] When the horizontal plate 631 drives the multiple wedge blocks 632 to move horizontally relative to the base 61 synchronously, the multiple rolling bodies 634 roll along the tops of the corresponding wedge blocks 632 and drive the lifting platform 633 and the support frame 62 to rise and fall synchronously relative to the base 61.

[0046] The combined action of multiple wedge blocks 632 and corresponding rolling elements 634 multiplies the lateral force exerted on the cross plate 631 by several times, transforming it into a vertical force that propels the lifting platform 633 upwards and downwards, thereby lifting the heavy, elongated workpiece A, the lifting platform 633, and the support frame 62 as a whole. Therefore, a relatively small driving force can be used to propel the cross plate 631 horizontally, resulting in lower costs and, correspondingly, a smaller driving force, which can meet the needs of installations with limited space and can be significantly reduced. Furthermore, the horizontally extending arrangement of the transverse movement assembly 63 also reduces the overall volume, further meeting the needs of installations with limited space.

[0047] Specifically, the transverse movement assembly 63 further includes a transverse movement cylinder 637. The main body of the transverse movement cylinder 637 is fixed on the base 61, and the driving end of the transverse movement cylinder 637 is fixedly connected to the transverse plate 631. The transverse movement cylinder 637 is used to drive the transverse plate 631 to move horizontally.

[0048] Since the driving force required of the driving member that pushes the horizontal plate 631 to move horizontally is relatively small, the driving member can use a transverse cylinder 637 instead of a hydraulic cylinder, which can correspondingly reduce the overall weight of the transverse assembly 63.

[0049] Preferably, a pneumatic one-way speed regulating valve is provided on the cylinder joint of the transverse cylinder 637 so that the support frame 62 can be raised and lowered smoothly relative to the base 61 to prevent the long workpiece A from falling and causing losses and safety hazards.

[0050] Specifically, the rolling element 634 is a roller bearing.

[0051] Specifically, a first horizontal guide rail 611 is provided on the top of the base 61 , a first slider 6311 is fixedly connected to the horizontal plate 631 , and the first slider 6311 is slidably connected to the first horizontal guide rail 611 .

[0052] When in use, the transverse plate 631 can move horizontally relative to the base 61 along the first horizontal guide rail 611 through the first slider 6311 to improve the movement accuracy of the transverse plate 631 .

[0053] Preferably, there are two first horizontal guide rails 61 , and the two first horizontal guide rails 61 are spaced apart along the width direction of the base 61 to improve the support stability of the transverse plate 631 .

[0054] Specifically, the traverse assembly 63 further includes a plurality of guide columns 635 and a plurality of linear bearings 636 .

[0055] The guide posts 635 are oriented vertically and are spaced apart along the length of the base 61. A plurality of linear bearings 636 correspond to the guide posts 635 one by one. The linear bearings 636 are mounted on corresponding guide posts 635 and can be raised and lowered relative to the guide posts 635. The linear bearings 636 are fixedly connected to the lifting platform 633.

[0056] Through the above arrangement, when multiple rolling bodies 634 roll along the top of the corresponding wedge blocks 632 and drive the lifting platform 633 and the support frame 62 to rise and fall synchronously relative to the base 61, the linear bearings 636 on the lifting platform 633 can rise and fall relative to the corresponding guide columns 635 to limit the lifting platform 633 to rise and fall in the vertical direction, thereby improving the movement accuracy.

[0057] Preferably, the base 61 is a box with an open upper end, and the inner cavity of the base 61 accommodates the transverse movement assembly 63 to protect the transverse movement assembly 63.

[0058] Furthermore, a second horizontal guide rail 5 is provided on the top of the platform, a second slider 612 is provided on the base 61 , and the second slider 612 is slidably provided on the second horizontal guide rail 5 .

[0059] The base 61 can move horizontally relative to the platform along the second horizontal guide rail 5 via the second slider 612 , so as to improve the accuracy of the horizontal movement of the base 61 .

[0060] Preferably, there are two second horizontal guide rails 5 , and the two second horizontal guide rails 5 are spaced apart along the width direction of the platform to improve the support stability of the entire material moving mechanism.

[0061] Specifically, the second horizontal guide rail 5 is a rack and pinion slide rail, and is driven by a transverse driving assembly 638. The transverse driving assembly 638 is a reduction motor.

[0062] It should be noted that the material moving mechanism is arranged in a horizontally extending manner as a whole, so that its width is only about 380 mm, so that the overall layout is compact and meets the installation conditions with limited space.

[0063] Furthermore, the following settings of the material shifting mechanism are adopted: the horizontal plate 631 can be horizontally moved relative to the base 61 along the first horizontal guide rail 611 through the first slider 6311, the base 61 can be horizontally moved relative to the platform along the second horizontal guide rail 5 through the second slider 612, the linear bearing 636 on the lifting platform 633 can be raised and lowered relative to the corresponding guide column 635, and the cylinder joint of the transverse cylinder 637 is provided with a pneumatic one-way speed regulating valve, so that the support frame 62 can drive the elongated workpiece A to move horizontally and the movement during the lifting process is smooth, thereby avoiding creeping and jamming. At the same time, the material shifting mechanism as a whole moves horizontally relative to the platform to a set distance to drive the elongated workpiece A to move horizontally relative to the support mechanism by the set distance, and the horizontal movement of the horizontal plate 631 drives the support frame 62 to synchronously rise and fall relative to the base 61 to the state of being at the material shifting height and the release height to push the elongated workpiece A forward, thereby ensuring the consistency of the set distance of the horizontal movement of the elongated workpiece A relative to the support frame 62, thereby ensuring the consistency of the length of each cutting section.
