[0002] In recent years, wire cutting has been used to cut hard and brittle rods. In order to improve processing efficiency, a multi-station cutting mechanism is generally used to cut silicon rods and cut the silicon rods into multiple sections. In the prior art, multiple cutting mechanisms are installed together on an integral lifting beam mechanism, and the integral lifting beam mechanism drives all cutting mechanisms to feed simultaneously; the existing cutting mechanism has a large structure, heavy weight, a large feed mechanism load, and high energy consumption; when the number of cutters is less than the number of cutting heads, a lot of useless work is consumed. The support components in the prior art are fixed, and the cutting line must be cut from the gap reserved between the support components. Since the support components are fixed, it is not conducive to cutting hard and brittle rods of any length, and the support position of the hard and brittle rods cannot be adjusted, which is not conducive to use in segmented cutting.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0091] In the description of this specification, it should be understood that the directional words such as "upper", "lower", "left", and "right" described in the embodiments of the present application are described at the angles shown in the accompanying drawings and should not be understood as limitations on the embodiments of the present application. In addition, in the context, it should also be understood that when it is mentioned that an element is connected to another element "upper" or "lower", it can not only be directly connected to another element "upper" or "lower", but also indirectly connected to another element "upper" or "lower" through an intermediate element.

[0092] See also Figures 1 to 16This embodiment discloses a multi-station cutting machine, which includes a feeding mechanism 1, a clamping mechanism 2, a cutting mechanism 3 and a material receiving mechanism 4. The feeding mechanism 1, the cutting mechanism 3 and the material receiving mechanism 4 are arranged in sequence along the processing direction. The clamping mechanism 2 is arranged below the cutting mechanism 3, and the clamping mechanism 2 is used to clamp hard and brittle rods 5.

[0093] Optional, such as Figures 1 to 3 As shown, the feeding mechanism 1 includes a feed rack body 11, more than two support wheel groups 12 and a second power assembly 13. The support wheel group 12 includes two support wheels 121 relatively arranged on the feed rack body 11. The two relatively arranged support wheels 121 are used to support hard and brittle bars 5. The more than two support wheel groups 12 are arranged in sequence on the feed rack body 11. The second power assembly 13 is connected to each support wheel 121 in a transmission manner. The second power assembly 13 is used to drive each support wheel 121 to rotate around the axis to transport the hard and brittle bars 5. The second power assembly 13 is a motor, which is used to drive all the support wheels 121 to rotate through the cooperation of the sprocket and the chain 15. In this way, each support wheel 121 has independent power, and hard and brittle bars 5 of any length can be guaranteed to have sufficient power to be transported forward at any position. The degree of automation is high, and the transportation of hard and brittle bars 5 is convenient.

[0094] Optionally, the feeding mechanism 1 further includes a lateral wheel frame group 14, which includes two relatively arranged lateral wheel frames, and the two relatively arranged lateral wheel frames are respectively arranged on both sides of the feed frame body 11, and the lateral wheel frame group 14 is used to prevent the hard and brittle bars 5 from tipping over.

[0095] The feeding mechanism 1 includes more than two lateral wheel frame groups 14, which are arranged in sequence on the feed frame body 11. The lateral wheel frames are fixed on the feed frame body 11, and rollers are provided on the lateral wheel frames. The lateral wheel frames are used to limit the rollover of the hard and brittle bars 5 through the rollers. In this way, the lateral wheel frames can be fixed on both sides of the feed frame body 11 by welding or bolts, which can effectively prevent the hard and brittle bars 5 from falling off the conveyor belt formed by the support wheels 121 during the transmission process.

[0096] Optional, such as Figure 4 , Figure 5 The multi-station cutting machine also includes a transmission wheel frame 6 and a wheel frame lifting mechanism 7. The transmission wheel frame 6 is arranged between the clamping mechanism 2 and the cutting mechanism 3. The transmission wheel frame 6 is provided with more than two supporting wheel groups 12. The more than two supporting wheel groups 12 are arranged in sequence on the transmission wheel frame 6. The supporting wheel group 12 includes two supporting wheels 121 arranged oppositely on the transmission wheel frame 6. The two supporting wheels 121 arranged oppositely are used to transport hard and brittle bars 5.

[0097] The wheel frame lifting mechanism 7 is arranged on one side of the transmission wheel frame 6, and the transmission wheel frame 6 is arranged on the lifting part 71 of the wheel frame lifting mechanism 7. The wheel frame lifting mechanism 7 is used to lift or lower the transmission wheel frame 6 so that the hard and brittle bar 5 on the transmission wheel frame 6 is placed on or lifted off the clamping mechanism 2. The transmission wheel frame 6 transports the hard and brittle bar 5 to the top of the clamping mechanism 2 through the supporting wheel 121. The supporting wheel 121 of the transmission wheel frame 6 has the same structure as the supporting wheel 121 of the feeding mechanism 1; the wheel frame lifting mechanism 7 is lowered, and the hard and brittle bar 5 is placed on the clamping mechanism 2 for cutting; after the cutting is completed, the wheel frame lifting mechanism 7 is raised, and the hard and brittle bar 5 is lifted off the clamping mechanism 2, so that the hard and brittle bar 5 is transported away. In this way, the processing of the hard and brittle bar 5 is facilitated and the processing efficiency is improved.

[0098] Optional, such as Figure 6 as well as Figure 7 As shown, the cutting mechanism 3 includes a cutting frame 31 and more than two cutting components 32. The more than two cutting components 32 are arranged in sequence on the cutting frame 31. The cutting component 32 includes a power unit 321, a lifting component and a cutting component. The cutting component is arranged on one side of the cutting frame 31 through the lifting component. The power unit 321 is used to drive the lifting component to drive the cutting component to rise and fall.

[0099] Each cutting assembly 32 is provided with a power unit 321 and a lifting component, and each power unit 321 controls a lifting component independently. In this way, the cutting assembly 32 is provided with a separate lifting component, and can perform cutting independently; if the length of the rod to be cut is short, only a few cutting operation mechanisms can be started, and no useless energy consumption will be generated.

[0100] Optionally, the cutting assembly 32 is arranged on the frame 31 through two parallel cutting slide rails 311, and each cutting assembly 32 can slide relatively along the extension direction of the cutting slide rail 311, so as to change the cutting position.

[0101] Optionally, the cutting assembly 32 further includes a cover plate 324, which is fixed to the cutting assembly 32 through a hook structure, a fixing block 325 is provided on the cutting assembly 32, a groove is provided on the fixing block 325, a hook 326 is provided on the cover plate 324, and the cover plate 324 is fixed to the cutting assembly 32 through the cooperation between the hook 326 and the groove. The cover plate 324 is fixed to the upper end of the cutting assembly 32 through the hook structure, which is simple and reliable, and the hook structure and the fixing structure are both provided on the top or side of the cutting assembly 32, saving the longitudinal space between adjacent cutting assemblies 32.

[0102] like Figures 8 to 12As shown, the clamping mechanism 2 includes a base 21, more than two support assemblies 22 and a first power assembly 23. A sliding track 211 is arranged on the base 21. The support assembly 22 includes a slider 221, a bracket 222 and a support component 223. The bracket 222 is arranged on the base 21 through the cooperation of the slider 221 and the sliding track 211. The support component 223 is arranged on the bracket 222. The support component 223 is used to support the hard and brittle rod 5.

[0103] More than two support assemblies 22 are arranged in sequence along the processing direction on the base 21, and a gap is set between two adjacent support assemblies 22 to allow the cutting mechanism 3 to pass through. The first power assembly 23 is used to drive the support assembly 22 to move relatively along the sliding track 211 and change the distance between adjacent support assemblies 22; in this way, the distance between the support assemblies 22 can be changed by the first power assembly 23, and the position of the support assembly 22 alone can cut hard and brittle rods 5 of any length, and the support component 223 can be adjusted together with the support assembly 22, thereby adjusting the cutting position of the hard and brittle rod 5.

[0104] Optionally, a rack 212 is provided on the base 21, and the rack 212 is arranged parallel to the sliding track 211. The support assembly 22 includes a gear 224, and the gear 224 is meshed with the rack 212. The first power assembly 23 includes a second power source 232, and the second power source 232 is transmission-connected with the gear 224. The second power source 232 is used to drive the gear 224 to rotate, and the gear 224 is meshed with the rack 212. The rack 212 and the sliding track 211 are parallel to each other, thereby driving the support assembly 22 to move relative to each other along the extension direction of the sliding track 211.

[0105] Optionally, a limit assembly 24 is provided between two adjacent support assemblies 22, and the limit assembly 24 includes a limit sensor 241 and a limit rod 242. The limit sensor 241 is provided on one of the adjacent support assemblies 22, and the limit rod 242 is provided on the other adjacent support assembly 22. The limit rod 242 cooperates with the limit sensor 241 to maintain the distance between the two adjacent support assemblies 22. At this time, the sensor and the limit rod 242 are used to limit the distance between the adjacent support assemblies 22. If the limit rod 242 is close to the sensor, the second power source 232 is stopped from continuing to drive the gear 224 to rotate, so as to prevent the two adjacent assemblies from colliding or interfering with each other, thereby affecting the cutting efficiency.

[0106] Optional, such as Fig.11 as well as Fig.12The support assembly 22 includes a first bracket 2221 and a second bracket 2222 . The first bracket 2221 and the second bracket 2222 are arranged in sequence along the extending direction of the sliding track 211 . The first bracket 2221 and the second bracket 2222 are respectively arranged on the sliding track 211 through the slider 221 .

[0107] The first power assembly 23 includes a first power source 231, a fixed end of the first power source 231 is disposed on the first bracket 2221, a movable end of the first power source 231 is connected to the second bracket 2222, and the first power source 231 is used to drive the second bracket 2222 to approach or move away from the first bracket 2221. In this way, the distance between the first bracket 2221 and the second bracket 2222 can be driven in a small range, so that the support assembly 22 is suitable for hard and brittle bars 5 of different lengths.

[0108] Optional, such as Figure 8 , Fig. 9 , Fig.13 as well as Fig.14 The multi-station cutting machine also includes a protection mechanism, which includes a rolling support assembly 81 and a protective cover body 82.

The rolling support assembly 81 also includes a rolling shaft 812 and an adjustment seat 813. The adjustment seat 813 is arranged on the bracket 222, the rolling shaft 812 is arranged on the adjustment seat 813, the rolling wheel 811 is arranged on the rolling shaft 812, and the rolling wheel 811 rotates around the axial direction of the rolling shaft 812. In this way, the protective cover body 82 can move relatively along the extension direction of the bracket 222, and the rolling support assembly 81 supports the protective cover body 82, thereby avoiding the problem of sagging and deformation of the protective cover body 82 with a long span.

The third power assembly 43 is used to drive the wheel frames 42 to move relatively along the extension direction of the track 411. In this way, more than two wheel frames 42 can be arranged on one frame. After one wheel frame 42 is fully loaded with hard and brittle bars 5, the third power assembly 43 drives the second wheel frame 42 to continue to receive materials, so that alternate receiving of materials can be achieved and space can be saved.

[0110] Different from the prior art, the above technical solution is to load the material through the loading mechanism 1, the clamping mechanism 2 clamps the hard and brittle rod 5, the cutting mechanism 3 cuts the hard and brittle rod 5, and the receiving mechanism 4 receives the processed hard and brittle rod 5. Each support wheel 121 has power, and the first power component 23 is used to drive the support component 22 to move relatively along the sliding track 211 and change the distance between adjacent support components 22; each cutting component 32 is correspondingly provided with a power unit 321 and a lifting component, and each power unit 321 controls a lifting component separately.
