[0039] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0040] The present invention provides a squaring machine with improved material replacement efficiency, which is used for processing hard and brittle materials, such as single crystal silicon rods, and cuts the rod material 5 into cubes, that is, performs squaring operations. In particular, the material replacement process is efficient and the whole machine is compact.

[0041] See also Figure 1 and Figure 2 In a specific embodiment, the square cutting machine includes a loading mechanism 1, a feeding mechanism 2, a cutting feeding mechanism 3 and a cutting running mechanism 4; the loading mechanism 1 is used to convey the bar material 5 to the receiving mechanism of the feeding mechanism 2 described below; the cutting running mechanism 4 is used to cut the bar material 5; the loading mechanism 1 is used to facilitate the user to deliver the bar material 5 to be processed to the feeding mechanism 2; the feeding mechanism is used to deliver the bar material 5 to be squared to the cutting feeding mechanism 3, and to transport the squared bar material 5 away from the cutting running mechanism 4; the cutting feeding mechanism 3 is used to drive the bar material 5 to be cut to move along the cutting path of the cutting running mechanism 4; the cutting running mechanism 4 is used to cut the bar material 5, specifically to cooperate with the cutting mechanism to realize the relative movement of the cutting running mechanism 4 and the bar material 5, thereby completing the cutting of the bar material 5.

[0042] The square cutting machine also includes a machine base 6 and a machine casing 7. The cutting operation mechanism 4 is arranged on the machine base 6. The cutting operation mechanism 4 and the cutting feeding mechanism 3 are both arranged in the machine casing 7, and a channel for the material receiving and feeding mechanism 2 to shuttle is opened.

[0043] The user manually places the bar material 5 to be processed on the loading mechanism 1. In particular, the loading mechanism 1 can be used to conveniently and safely place the bar material 5 on the loading mechanism 1 with relatively little effort. Figure 3 The feeding mechanism 1 includes a material rack 10, a lifting mechanism and a base 19; the material rack 10 is a component for supporting the rod material 5 to be processed, and its length should be greater than the conventional length of the rod material 5 to be processed at present; the lifting mechanism is used to realize the raising and lowering of the material rack 10. When it is necessary to manually feed the material to the feeding mechanism 1, the material rack 10 is driven to descend to a lower height. After the single crystal silicon rod is placed on the feeding mechanism 1, the material rack 10 is driven to rise to a height where the single crystal silicon rod can be smoothly pushed to the clamping claw of the receiving mechanism; the base 19 is the base of the feeding mechanism 1, and the lifting mechanism is arranged at the base 19.

[0044] The two sides of the material rack 10 are symmetrically bent upward, and at least two rollers 11 are respectively arranged on both sides of the material rack 10. The rollers 11 are arranged in sequence along the length direction of the material rack 10, and are rotatably connected to the material rack 10, and all protrude upward from the material rack 10 to rollingly support the single crystal silicon rod; after the single crystal silicon rod is placed on the material rack 10, the single crystal silicon rod is pushed, and under the interaction between the single crystal silicon rod and the rollers 11, the single crystal silicon rod can be conveniently continued to be pushed.

[0045] The lifting mechanism includes a lifting drive mechanism, a support plate 12 and two groups of supporting components; the support plate 12 is used to support the material rack 10 and provide a driving force point for the lifting drive mechanism. The material rack 10 is supported by the support plate 12 on the base 19; the lifting drive mechanism is arranged at the base 19 and is transmission-connected to the support plate 12, and is used to drive the support plate 12 to lift and lower the material rack 10.

[0046] Two groups of support components are respectively located on both sides of the material rack 10, and the support components include a plurality of slide bars 13, which are sequentially arranged along the length direction of the material rack 10, and the slide bars 13 can vertically move through the base 19, and the top of the slide bars 13 is connected to the support plate 12. When the lifting drive mechanism drives the material rack 10 to rise, the slide bars 13 rise relative to the base 19 along with the support plate 12 driven by the lifting drive mechanism, and when the lifting drive mechanism drives the material rack 10 to fall, the slide bars 13 fall relative to the base 19 along with the support plate 12 driven by the lifting drive mechanism. By cooperating with the lifting drive mechanism, the lifting direction of the material rack 10 can be limited, especially to avoid the problem of skewing caused by the gravity of the single crystal silicon rods themselves during the rising process, and at this time, it plays a role in protecting the lifting drive mechanism to avoid the output end of the lifting drive mechanism from being damaged.

[0047] The lifting drive mechanism may include a pneumatic cylinder, an oil cylinder or a linear motor, and the body of the lifting drive mechanism is arranged at the base 19; the output end of the lifting drive mechanism is arranged vertically and upward, and is connected to the support plate 12, specifically, the end face of the output end of the lifting drive mechanism is connected to the bottom surface of the support plate 12.

[0048] In order to drive the material rack 10 to rise or fall more smoothly, in a preferred embodiment, the lifting drive mechanism includes a vertical plate 14, a lifting cylinder 15, a sprocket mounting seat 16, two chains 17 and two sprockets 18; the vertical plate 14 is erected under the support plate 12; the lifting cylinder 15 is arranged at the base 19, and the output end of the lifting cylinder 15 is arranged upward and connected to the sprocket mounting seat 16. Such an arrangement makes it possible for the sprocket mounting seat 16 to rise when the output end of the lifting cylinder 15 is extended, and the sprocket mounting seat 16 to fall when the output end of the lifting cylinder 15 is shortened.

[0049] Two sprockets 18 are symmetrically arranged on both sides of the sprocket mounting seat 16, and both sprockets 18 are rotatable; the two sprockets 18 have a common rotation axis, and the rotation axis is parallel to the vertical plate 14 and orthogonal to the output end of the lifting cylinder 15. One end of two chains 17 are connected to the vertical plate 14; the other end of one chain 17 passes around a sprocket 18 and is connected to the base 19, and the sprocket 18 is meshed with the chain 17; the other end of the other chain 17 passes around another chain 17 and is connected to the base 19, and the sprocket 18 is meshed with the chain 17. During the extension of the output end of the lifting cylinder 15, the sprocket mounting seat 16 will rise with the output end of the lifting cylinder 15. At this time, the sprocket moves upward along the vertical plate 14, and the chain 17 is continuously pressed to the vertical plate 14 by the moving sprocket, that is, the sprocket continues to move upward at the chain 17, the entire vertical plate 14 is lifted upward, and the material rack 10 rises accordingly; during the shortening of the output end of the lifting cylinder 15, the sprocket mounting seat 16 will descend with the output end of the lifting cylinder 15. At this time, the sprocket moves downward along the vertical plate 14, the chain 17 is continuously sent away from the vertical plate 14, the entire vertical plate 14 descends, and the material rack 10 descends accordingly.

[0050] When it is necessary to place the single crystal silicon rod to be processed on the loading mechanism 1, the lifting drive mechanism drives the material rack 10 to descend to a height at which the user can conveniently place the single crystal silicon rod on the loading mechanism 1. The user can conveniently, labor-savingly and safely place the single crystal silicon rod to be processed on the loading mechanism 1, and then the lifting drive mechanism drives the material rack 10 to rise to a height at which the single crystal silicon rod can be smoothly pushed to the clamping claws of the receiving mechanism.

[0051] Since the base 19 has a certain height, in order to allow the material rack 10 to be lowered to a lower height, in a further embodiment, the base 19 is provided with a clearance opening 190, and the lifting drive mechanism is arranged below the base 19. The lifting drive mechanism and the vertical plate 14 can both pass through the clearance opening 190 from bottom to top to the base 19. This arrangement allows the material rack 10 to be lowered to a height that can touch the top surface of the base 19. When the material rack 10 is lowered to a height that can touch the top surface of the base 19, the lifting drive mechanism can be completely retracted under the base 19 to avoid collision with the lifting drive mechanism when the single crystal silicon rod is manually placed on the material rack 10, thereby damaging the lifting drive mechanism.

[0052] A mounting seat is provided below the clearance opening 190 , and the mounting seat is fixedly provided below the base 19 . The lifting drive mechanism passes through the clearance opening 190 and is provided at the mounting seat. The ends of the chains 17 that are not connected to the vertical plate 14 are connected to the mounting seat.

[0053] In order to ensure that the material rack 10 descends more smoothly, in a further embodiment, the base 19 is provided with a buffer 110 , and the buffer 110 is located under the support plate 12 . A spring is provided in the buffer 110 , and the buffer 110 is used to buffer the descending material rack 10 .

[0054] In a further embodiment, a limit block 111 is provided on the base 19, and the support plate 12 is driven by the lifting drive mechanism to descend to abut against the limit block 111. The limit block 111 is used to limit the lowest height of the material rack 10 after it descends. By setting the height of the limit block 111, the lowest height of the material rack 10 can be adjusted. The limit block 111 can be set at the base 19 by bolts, and the limit blocks 111 of different heights can be replaced according to the required height. In a preferred embodiment, two limit blocks 111 are provided, and the two limit blocks 111 are located under the two ends of the material rack 10.

[0055] The feeding mechanism 2 is arranged at the feeding port of the cutting mechanism 4, see Figure 4 The material receiving and feeding mechanism 2 includes a material receiving mechanism, a material receiving drive mechanism 24, a material feeding mechanism, a material feeding drive mechanism 29 and a material receiving and feeding base 210; the material receiving mechanism is used to receive the rod material 5 to be cut, and the material receiving drive mechanism 24 is used to drive the material receiving mechanism to move laterally, that is, to move in a direction perpendicular to the cutting path of the cutting operation mechanism 4, and to and from one side of the cutting operation mechanism 4 and directly opposite to the feed port of the cutting operation mechanism 4; the feeding mechanism is used to receive the cut rod material 5, and the material feeding drive mechanism 29 is used to drive the feeding mechanism to move laterally, also to move in a direction perpendicular to the cutting path of the cutting operation mechanism 4, and to and from one side of the cutting operation mechanism 4 and directly opposite to the feed port of the cutting operation mechanism 4.

[0056] The material receiving mechanism and the material feeding mechanism can both be arranged at the material receiving and feeding base 210 so as to be laterally movable. The material receiving and feeding base 210 may be provided with a first track 211, and preferably two first tracks 211 are provided, and the two first tracks 211 are arranged laterally and side by side. The material receiving mechanism may be arranged at one of the first tracks 211, and the material feeding mechanism may be arranged at the other first track 211; or the material receiving mechanism may be connected to the two first tracks 211, and the material feeding mechanism may also be connected to the two first tracks 211, the material receiving mechanism may be arranged at one end of the first track 211, and the material feeding mechanism may be arranged at the other end of the first track 211, and the material receiving mechanism and the material feeding mechanism may move alternately in the middle of the first track 211.

[0057] The material receiving drive mechanism 24 is connected to the material receiving mechanism in a transmission manner to drive the material receiving mechanism to move laterally; the material feeding drive mechanism 29 is connected to the material feeding mechanism in a transmission manner to drive the material feeding mechanism to move laterally. The material receiving drive mechanism 24 and the material feeding drive mechanism 29 can both include a screw motor, the screw of the screw motor is screwed with a transmission nut, the screw motor is arranged at the material receiving and feeding base 210, and the axial direction of the screw of the screw motor is arranged parallel to the first track 211, the transmission nut of the material receiving drive mechanism 24 is connected to the material receiving mechanism, and the transmission nut of the material feeding drive mechanism 29 is connected to the material feeding mechanism. Under the threaded transmission action of the screw of the screw motor and the transmission nut, the material receiving mechanism and the material feeding mechanism can be driven to move laterally.

[0058] The material receiving mechanism includes a clamping jaw, which is used to clamp the rod 5 to be cut. The clamping jaw includes a clamping jaw driving mechanism 20, a clamping jaw seat, and two clamping jaws 21; the two clamping jaws 21 are sequentially arranged at the clamping jaw seat along the horizontal direction; the clamping jaw driving mechanism 20 is transmission-connected to the clamping jaws 21 to drive the two clamping jaws 21 to laterally approach and clamp the rod 5 or move away from and release the rod 5.

[0059] Through the material receiving drive mechanism 24, the material receiving mechanism can move laterally alone, and through the feeding drive mechanism 29, the feeding mechanism can also move laterally alone. When the operation starts, the rod 5 is pushed to the material receiving mechanism through the loading mechanism 1, and the two claws 21 of the material receiving mechanism are in a distant state, that is, the rod 5 can be pushed between the two claws 21, and then the claw driving mechanism 20 drives the two claws 21 to approach to clamp the rod 5, and drives the material receiving mechanism to move laterally to the moving path of the cutting feed mechanism 3, and the clamping mechanism clamps the rod 5 at the material receiving mechanism and sends the rod 5 to the cutting operation mechanism 4 for cutting. After the cutting is completed, the clamping mechanism puts the rod to the feeding mechanism, and the rod is sent out through the feeding mechanism. During the cutting process, the material receiving mechanism can continue to clamp the next rod to be cut. Therefore, the feeding mechanism alone completes the work of transporting the squared bars away from the cutting operation mechanism 4, and the receiving mechanism alone completes the work of transporting the bars to be squared to the cutting feed mechanism 3. The cooperation between the feeding mechanism and the receiving mechanism makes the entire material changing process efficient.

[0060] In a further embodiment, a transverse track is provided on the top surface of the clamping jaw seat, and the two claw bodies 21 can be disposed on the transverse track so as to be movably disposed transversely. The claw body driving mechanism 20 may include two linear motors, and the output shafts of the two linear motors are respectively connected to the two claw bodies 21 to drive the two claw bodies 21 to move closer or farther away. Before the bar needs to be clamped, the two linear motors drive the two claw bodies 21 to move in opposite directions until the distance between the two claw bodies 21 is sufficient to accommodate the bar. When the bar is pushed between the two claw bodies 21, the two linear motors drive the two claw bodies 21 to move in opposite directions until the two claw bodies 21 clamp the bar. At this time, the feeding driving mechanism 29 is started to drive the feeding mechanism to move transversely until the bar is directly opposite to the feeding port of the cutting operation mechanism 4.

[0061] In a further embodiment, at least two claw bodies 21 may be provided, and the claw bodies 21 are arranged in sequence along the longitudinal direction to clamp the bar together. The claw bodies 21 may share a claw body seat, and the claw bodies are all arranged at a claw body seat.

[0062] In order to more stably support the bar material to be cut, in a further embodiment, the material receiving mechanism further includes a material receiving support frame, which is arranged between the two claws of the claw body, and includes a material receiving frame 22 and at least two sets of material receiving support wheel groups, each of which is arranged in sequence along the longitudinal direction; the material receiving support wheel group includes two oppositely arranged material receiving support wheels 23, and the two oppositely arranged material receiving support wheels 23 jointly roll and support the bar material. When the material receiving mechanism needs to receive the bar material to be cut, the material frame of the feeding mechanism 1 and the material receiving support frame of the material receiving mechanism are aligned so that the bar material on the material frame can be pushed onto the material receiving support frame along the axial direction of the bar material and clamped by the clamping claws.

[0063] The material receiving support frame and the clamping jaws are both arranged on the material receiving base, and the material receiving support frame is located on the clamping jaw seat of the clamping jaw, and the two jaw bodies of the clamping jaw are located on both sides of the material receiving support frame. The material receiving drive mechanism 24 is transmission-connected with the material receiving base to drive the entire material receiving mechanism to move horizontally.

[0064] In a further embodiment, the material receiving mechanism also includes a material receiving longitudinal moving mechanism, the material receiving longitudinal moving mechanism is arranged on the material receiving seat, the clamping claw is arranged on the material receiving longitudinal moving mechanism, and the material receiving longitudinal moving mechanism is used to drive the clamping claw to move longitudinally. If a material receiving support frame is provided, the clamping claw moves longitudinally along the material receiving support frame.

[0065] After the bar material is cut, it is necessary to place the feeding mechanism to send the bar material away from the cutting operation mechanism 4, that is, the feeding mechanism has a position for placing the bar material. In addition, in order to collect the edge skin for the convenience of cleaning the edge skin, in a certain embodiment, the feeding mechanism includes a square bar receiving mechanism, an edge skin receiving mechanism 27 and a feeding seat 28; the square bar receiving mechanism is used to receive square bars; the edge skin receiving mechanism 27 is used to receive edge skin; the square bar receiving mechanism and the edge skin receiving mechanism 27 are arranged in sequence on the feeding seat 28 along the horizontal direction; the feeding drive mechanism 29 is connected to the feeding seat 28 in transmission.

[0066] In a further embodiment, the edge skin receiving mechanism 27 includes an edge skin groove for accommodating the edge skin. When the edge skin needs to be placed, it is only necessary to move the feeding mechanism horizontally so that the edge skin groove is located under the edge skin, and the edge skin naturally falls into the edge skin groove. The square rod receiving mechanism includes a feeding support frame, and the feeding support frame includes a feeding frame 25 and at least two groups of feeding support wheel groups. Each feeding support wheel group is sequentially arranged along the longitudinal direction. The feeding support wheel group includes two feeding support wheels 26 arranged opposite to each other. The two feeding support wheels 26 arranged opposite to each other jointly support the square rod.

[0067] In a further embodiment, the square rod receiving mechanism also includes a feeding lifting mechanism, the feeding lifting mechanism is arranged on the feeding seat 28, the feeding support frame is arranged on the feeding lifting mechanism, and the feeding lifting mechanism is used to drive the feeding support frame to rise and fall.

[0068] When the receiving mechanism delivers the bar material to be cut to the position opposite to the feed port of the cutting operation mechanism 4, the cutting feed mechanism 3 is required to take the bar material to be cut and drive the bar material to be cut into the cutting operation mechanism 4. Please refer to Figure 5 and Figure 6 In a further embodiment, the cutting feed mechanism 3 includes a bracket 30, a feed drive mechanism 31, and a clamping mechanism; the bracket 30 is used to place the clamping mechanism, and the feed drive mechanism 31 is used to drive the clamping mechanism to move longitudinally to travel back and forth between the cutting operation mechanism 4 and the feeding mechanism 2; the clamping mechanism is used to clamp the bar material.

[0069] The support 30 is mounted on the cutting and transporting mechanism and the material receiving and feeding mechanism 2 so that the clamping mechanism is overhead, so that the overall structure of the square opening machine is compact, stable, and small in size, and can travel back and forth between the cutting operation mechanism 4 and the material receiving and feeding mechanism 2. Specifically, the support 30 can be a gantry, which includes a top beam and two columns, and the two ends of the top beam are respectively connected to the two columns. The top beam is longitudinally arranged, that is, arranged along the cutting path of the cutting operation mechanism 4. The top beam is provided with a longitudinal second track 300, and the clamping mechanism is movably arranged at the second track 300. The feed drive mechanism 31 is connected to the clamping mechanism in a transmission manner to drive the clamping mechanism to move along the second track 300. Similarly, the feed drive mechanism 31 can also be a screw motor, and the screw of the screw motor is screwed with a transmission nut, and the transmission nut is connected to the clamping mechanism. When the screw motor is started, the clamping mechanism is driven to move along the second track 300 by means of threaded transmission.

[0070] In a further embodiment, the clamping mechanism includes a front clamping mechanism, a rear clamping mechanism, a clamping drive mechanism 32 and a clamping frame 33. The clamping frame 33 is arranged at the bracket 30, specifically, the clamping frame 33 is arranged at the second track 300 of the bracket 30, and the feed drive mechanism 31 is connected to the clamping frame 33 in a transmission manner, and is used to drive the clamping frame 33 to move longitudinally. The front clamping mechanism and the rear clamping mechanism are arranged opposite to each other, and are arranged at the clamping frame 33 in sequence along the longitudinal direction. Specifically, the clamping frame 33 is provided with a longitudinal third track 330, and the front clamping mechanism and the rear clamping mechanism can be movably arranged at the third track 330 along the third track 330, and the front clamping mechanism and the rear clamping mechanism are respectively in contact with the two end surfaces of the bar material to clamp the bar material together; the clamping drive mechanism 32 is used to drive the front clamping mechanism and the rear clamping mechanism to move closer or farther.

[0071] Before the bar needs to be clamped, the clamping drive mechanism 32 drives the front end clamping mechanism and the tail end clamping mechanism to move away until the distance between the front end clamping mechanism and the tail end clamping mechanism is greater than the length of the bar, and then drives the front end clamping mechanism and the tail end clamping mechanism to move closer until the bar is clamped. At this time, the feeding drive mechanism 31 drives the clamping mechanism to move into the cutting operation mechanism 4, and cooperates with the cutting operation mechanism 4 to cut the bar. After the cutting is completed, the feeding drive mechanism 31 drives the clamping mechanism to move to the outside of the feed port of the cutting operation mechanism 4, waits for the feeding mechanism to move to the feed port of the cutting operation mechanism 4, and then places the cut bar at the feeding mechanism.

[0072] In order to be able to deliver the edge skin to the edge skin receiving mechanism 27 of the feeding mechanism, in a further embodiment, the front end clamping mechanism and the rear end clamping mechanism both include a central clamping unit 34 and two edge skin clamping units 35; the central clamping unit 34 is arranged between the two edge skin clamping units 35, and the central clamping unit 34 of the front end clamping mechanism and the central clamping unit 34 of the rear end clamping mechanism face each other, and the two central clamping units 34 clamp the cut bar material together. The two edge skin clamping units 35 of the front end clamping mechanism and the two edge skin clamping units 35 of the rear end clamping mechanism face each other one by one, and the two facing edge skin clamping units 35 clamp the cut edge skin together.

[0073] The center clamping unit 34 includes a clamping seat 340, a center shaft and a rotating motor 341. The clamping seat 340 is arranged at the clamping frame 33. The center shaft is rotatably arranged at the clamping seat 340. The rotating motor 341 is connected to the center shaft to drive the center shaft to rotate axially, thereby driving the bar to rotate axially. The edge clamping unit 35 includes an ejector block 350 and a cylinder 351. The output end of the cylinder 351 is connected to the ejector block 350 to drive the ejector block 350 to move longitudinally. Specifically, the cylinder 351 is arranged on the side of the clamping seat 340.

[0074] The clamping drive mechanism 32 drives the two center clamping units 34 to approach to clamp the bar material, and then the feed drive mechanism 31 drives the clamping mechanism to move to the cutting operation mechanism 4 for cutting, and then drives the clamping mechanism to move to the outside of the feeding port of the cutting operation mechanism 4, and the feeding mechanism moves until the edge skin receiving mechanism 27 is located under the edge skin, and the output end of the cylinder 351 of the edge skin clamping unit 35 is shortened to loosen the edge skin, and the edge skin falls to the edge skin receiving mechanism 27, and the rotating motor 341 drives the central shaft to rotate 9 0 degrees, the output end of the cylinder 351 of the edge skin clamping unit 35 extends to clamp the bar material, and the feed drive mechanism 31 continues to drive the clamping mechanism to enter the cutting operation mechanism 4. After cutting is completed, the clamping mechanism is driven to move to the outside of the feed port of the cutting operation mechanism 4, and then the edge skin is sent to the edge skin receiving mechanism 27, and then the feeding mechanism is moved until the square rod receiving mechanism is located under the clamping mechanism. The clamping mechanism places the cut bar material, that is, the square bar, on the square rod receiving mechanism, and then the next bar to be cut can be processed.

[0075] See also Figure 7 The cutting mechanism 4 includes a translation mechanism 41 and two cutting units 40, see Figure 8The cutting unit 40 includes a panel 400, a wheel set and a wire saw 402. The wheel set includes a plurality of guide wheels 401. The plurality of guide wheels 401 are all arranged on the same surface of the panel 400. The wire saw 402 is arranged in a ring shape at the wire groove of the guide wheel 401. The two cutting units 40 are provided with a guide wheel 401 on one side facing each other. The two cutting units 40 cut one side of the bar material respectively. The translation mechanism 41 includes a running seat 410 and a cutting unit driving mechanism 412. The two cutting units 40 are sequentially arranged on the running seat 410 in the horizontal direction, and the two cutting units 40 can move horizontally close to or away from each other. For details, please refer to Fig. 9 A fourth track 411 may be provided on the running seat 410, and the cutting unit driving mechanism 412 is used for the lateral movement of the cutting unit 40 so that the two cutting units 40 are moved closer or farther away.
