DETAILED DESCRIPTION

[0050] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is used as a reference. Figure 1 The positions of the first cutting head d, the second cutting head e, the first supporting device f and the second supporting device g relative to the processing platform a are defined as "upper"; the first cutting head d and the second cutting head e are arranged on the "left and right" sides relative to the processing platform a; the side perpendicular to the paper surface facing inward is defined as "back".

[0051] Reference Figure 1 As shown, a cutting production line proposed in an embodiment of the present invention includes a feeding device for cutting off the special-shaped tail of a silicon rod, a processing platform a, a supporting and positioning device, a first cutting blade head d and a second cutting blade head e.

[0052] The top of the processing platform a is provided with a movable guide rail of the same length as itself along its longitudinal direction (left-right length direction). The unloading device, the supporting and positioning device, the first cutting blade d and the second cutting blade e for cutting off the special-shaped tail of the silicon rod can all slide left and right along the movable guide rail on the processing platform a.

[0053] The supporting and positioning device is arranged between the first cutting blade d and the second cutting blade e. The bottom of the first supporting device f and the second supporting device g of the centering and positioning system, the bottom of the first cutting blade d and the bottom of the second cutting blade e can all move along the movable guide rail. Specifically, after the silicon rod is placed horizontally on the supporting and positioning device and adjusted and fixed, the first cutting blade d and the second cutting blade e at both ends of the silicon rod are used to cut the silicon rod from both ends to form a plurality of silicon rod units of the length required for subsequent processing.

[0054] It should be noted that before the two cutting heads start cutting, the centering positioning system needs to be determined so that the first cutting head d and the second cutting head e can make way for each other to cooperate with the cutting work.

[0055] In addition, before cutting, since the entire silicon rod is drawn, a wavy special-shaped tail b is formed during the drawing process, especially at the starting end of the silicon rod, i.e., the tail. Therefore, a material discharge device at the tail of the silicon rod is required to cooperate with the cutting head c on the second cutting blade e to cut the special-shaped tail b and discharge the special-shaped tail b to the discharge position.

[0056] Among them, see Figure 1-Figure 5 As shown, an automatic feeding device for cutting off the special-shaped tail of a silicon rod comprises a feeding body 1 and a supporting body 2 for cutting off the special-shaped tail of a silicon rod.

[0057] See also Figure 1 As shown, the blanking body 1 is arranged on the processing platform a, and the blanking body 1 can slide relatively along the length direction of the processing platform a to approach or move away from the special-shaped tail b.

[0058] Furthermore, the blanking body 1 includes a movable support 11 , a blanking support structure and a driving structure 12 .

[0059] It should be noted that the movable support 11 is slidably mounted on the processing platform a. Figure 4 The movable support 11 drives the entire material removal body 1 to slide left and right relative to the movable guide rail on the processing platform a through the travel motor, and drives the entire material removal device to slide left and right relative to the processing platform a along its length direction to cooperate with the removal of the special-shaped tail b.

[0060] See also Figure 4As shown, the material unloading support structure includes two brackets 13 symmetrically arranged relative to the front and rear ends of the silicon rod. The two brackets 13 are respectively connected to the front and rear ends of the movable support 11, and each bracket 13 includes a supporting inclined surface, and the two brackets 13 form a "V"-shaped support groove. This is to facilitate the support and unloading of the silicon rod as a whole. Even if there is a supporting positioning device to support the entire silicon rod, when the silicon rod needs to be cut, a part of the silicon rod needs to be placed on the bracket 13 on the unloading support structure, and then the silicon rod is cut by the cutting head c.

[0061] In this embodiment, the driving structure 12 is disposed between the two brackets 13 , and the driving structure 12 is fixedly connected to the movable support 11 , and the driving structure 12 can drive the supporting body 2 to slide along the length direction thereof.

[0062] Specifically, the driving structure 12 includes a moving slide, a servo motor, a lead screw and a lead screw nut. The moving slide is fixedly arranged on the moving support 11, and the output shaft of the moving motor is axially and horizontally arranged at one end of the moving slide. The output end of the moving motor is fixedly connected to the lead screw, and the outer wall of the lead screw is screwed with the lead screw nut. The lead screw nut can slide horizontally along the length direction of the lead screw. The lead screw nut is connected to the support body 2, and the support body 2 can move along the slide rail on the moving slide. The driving structure 12 has a simple structure and low cost.

[0063] Furthermore, the support 13 includes a support 131 and a plurality of receiving cylinders 132. The support 131 has an inclined end surface inclined inwardly, and the plurality of receiving cylinders 132 are arranged at intervals on the inclined end surface.

[0064] Furthermore, the outer peripheral side wall of the extended end of the receiving cylinder 132 is sleeved with an elastic protective sleeve 133. It can protect the cylinder body and prevent cutting fluid from entering the cylinder during cutting, which affects the life of the cylinder.

[0065] In this embodiment, the support body 2 is arranged on the blanking body 1, and the support body 2 slides relative to the blanking body 1 along the length direction of the blanking body 1 to approach the special-shaped tail b. The support body 2 supports the special-shaped tail b, and the special-shaped tail b of the special-shaped tail b is cut by the cutting head c. After cutting, the support body 2 slides along the length direction (left and right direction) of the blanking body 1 to move away from the special-shaped tail b, and the special-shaped tail b falls on the blanking body 1.

[0066] Next, the blanking body 1 can drive the special-shaped tail b to be transported to the blanking position.

[0067] It should be noted that the unloading position is located on the left side of the processing platform a. A manipulator is arranged just above the unloading position, and then the unloading clamp manipulator takes the unloading material to the conveyor roller, completing the unloading fully automatically without manual labor.

[0068] Furthermore, the supporting body 2 includes a supporting structure 21 and a rotating structure 22 .

[0069] See also Figure 3 As shown, the supporting structure 21 is connected to the rotating structure 22, and the rotating structure 22 is connected to the blanking body 1. And it can move with the left and right lateral movement of the supporting structure 21. The blanking body 1 can drive the rotating structure 22 to drive the supporting structure 21 to support from the end face of one end of the special-shaped tail b.

[0070] Furthermore, the supporting structure 21 includes a supporting shell 211 and a plurality of adsorption units 212 .

[0071] It should be noted that see Figure 5 The support shell 211 has a hollow chamber, and a partition plate 2111 is arranged in the middle position of the hollow chamber to divide the hollow chamber into two chambers, and one end of the adsorption unit 212 is arranged in the chamber close to the left side of the hollow chamber, and a plurality of connecting pipes are arranged in the chamber on the right side for connecting with the external air pump and the adsorption unit 212, that is, providing an accommodation space for the connecting pipes.

[0072] Further, the right side wall end surface of the support shell 211 is connected to the rotating structure 22. One end (right end) of each adsorption unit 212 is disposed in the support shell 211, and the other end (left end) of each adsorption unit 212 extends horizontally and protrudes from the support shell 211.

[0073] It should be noted that before processing, the axis of the height of the support housing 211 and the axis of the silicon rod need to be ensured to be on the same horizontal line, which can be achieved by adjusting the horizontal position of the support positioning device where the silicon rod is located to ensure a better support effect.

[0074] In this example, each adsorption unit 212 has elastic force and can abut against the end surface of the special-shaped tail b one by one (see Figure 4 As shown in FIG. 1 , each adsorption unit 212 can be adsorbed and fixed on the end surface of the special-shaped tail b. It can adapt to special-shaped tails b of different shapes, thereby achieving a larger area of ​​contact with the special-shaped tail b to form a good support.

[0075] See also Figure 5 As shown, the adsorption unit 212 includes a horizontal adjustment guide rod 2121, a locking mechanism and a suction cup 2122. The horizontal adjustment guide rod 2121 includes a fixed end and an extended end, the fixed end is arranged in the inner cavity of the support shell 211, the extended end extends horizontally, and the extended end is fixedly connected to the suction cup 2122, and the extended end can drive the suction cup 2122 to reciprocate relative to the fixed end along its axial direction, so that the suction cup 2122 is against the special-shaped tail b.

[0076] It should be noted that an auxiliary elastic protective sleeve 2123 is provided on the outer side of the supporting cylinder 221 at the extended end of the horizontal adjustment guide rod 2121 , which can play a role in shock absorption and buffering, as well as protection of the horizontal adjustment guide rod 2121 .

[0077] In this embodiment, the locking mechanism is connected to the protruding end of the horizontal adjustment guide rod 2121 to lock the protruding end of the horizontal adjustment guide rod 2121.

[0078] Specifically, the locking mechanism (not shown in the figure) includes a locking driver, a transmission member and a plurality of locking wedges. The locking driver is fixedly installed in the support cylinder, the locking driver is connected to the transmission member, and the transmission member is fixedly connected to the locking wedges. The locking driver drives the transmission member to drive the plurality of locking wedges to move toward the corresponding buffer guide rods to lock the buffer guide rods.

[0079] Further, the transmission member includes two parallel locking movable guide rails and two locking arms arranged between the two locking movable guide rails, and the two locking arms are arranged centrally symmetrically with respect to the support tube. The transmission member can realize the transmission function, and no further elaboration is made here.

[0080] Each locking arm includes a connecting rod and a locking head. The connecting rod is arranged between two locking movable guide rails, and the two ends of the connecting rod are respectively formed integrally with the locking wedges to form a first locking portion and a second locking portion, and the bottom or top of the locking head is provided with a locking wedge to form a third locking portion.

[0081] Furthermore, the suction cup 2122 can be connected to an external air extraction component through a pipeline, so that a negative pressure state is formed between the suction cup 2122 and the special-shaped tail b. The special-shaped tail b can be better adsorbed, and when the two need to be separated, the external air pump is stopped, and the suction cup 2122 releases the negative pressure state with the special-shaped tail b, so that the support body 2 and the special-shaped tail b are separated.

[0082] In addition, the rotating structure 22 can drive the supporting structure 21 to rotate, so that the supporting structure 21 is in a vertical state or a horizontal state. In order to cooperate with the work of the unloading device, the supporting body 2 is made to give way.

[0083] In this embodiment, the rotating structure 22 includes a rotating cylinder 221 and a swing bracket 222. The output end of the rotating cylinder 221 is horizontally arranged, and the output end is connected to the bottom of one side wall of the swing bracket 222, and the top of the other side wall of the swing bracket 222 is fixedly connected to the support shell 211. The purpose of adding the rotating cylinder 221 is to rotate the first support unit 21 as a whole along its axis and lay it down (i.e. Figure 3 Rotate 90° counterclockwise) to make way for the robot at the unloading position.

[0084] Furthermore, the support body 2 also includes an auxiliary support structure 23. The auxiliary support structure 23 is arranged on one side of the support structure 21 close to the adsorption unit 212, and the auxiliary support structure 23 can support the bottom of the special-shaped tail b. Specifically, the auxiliary support structure 23 includes a support cylinder 231 and a support adsorption unit 232. The support adsorption unit 232 is driven by the support cylinder 231 to rise and fall to match the bottom support rod of the special-shaped tail b, and can adapt to special-shaped tails b of different heights. In addition, the structure of the support adsorption unit 232 is the same as the specific structure of the adsorption unit 212, except that the direction and position of adsorption are different. That is, the special-shaped tail b is further supported by the auxiliary support structure 23 to reduce the occurrence of edge collapse during cutting.

[0085] It should be noted that the left and right movement of the material unloading device on the processing platform a is achieved by driving the walking motor to approach or move away from the special-shaped tail b in the general direction. After the entire material unloading device approaches the special-shaped tail b, the driving structure 12 drives the supporting structure 21, the adsorption unit 22 and the auxiliary supporting structure 23 of the supporting body 2 to move toward the special-shaped tail b. Further move along the slide rail of the driving structure 12 to approach the shaped tail b, so that the shaped tail b just contacts the suction cup 2122 of the adsorption unit 22. At this time, the suction cup 2122 completely contacts the shaped tail b through its own elasticity and self-adaptation. The horizontal adjustment guide rod 2121 is locked and fixed by the locking mechanism, and the external air pump is started. The air pump draws air between the suction cup 2122 and the contact surface of the shaped tail b through the connecting pipe to be in a negative pressure state, thereby fixing the tail to cooperate with the cutting head c to cut the shaped tail b, and the bottom support block 221 of the second support unit 22 contacts the shaped tail b to form a good support. In addition, the auxiliary support structure can also move up and down under the support of the support cylinder 231 to support shaped tails b of different shapes, and can better support the shaped tail b.

[0086] This embodiment provides a feeding device for cutting off the shaped tail of a silicon rod, wherein the feeding body 1 drives the supporting body 2 to slide relative to the processing platform a to move toward the shaped tail b, until the supporting body 2 and the shaped tail b are against each other to support from one end and the bottom of the silicon rod respectively, so as to cooperate with the cutting head to cut the tail of the silicon rod, and transport the cut shaped tail b to the feeding position for full-automatic feeding, without manual feeding, thus improving the feeding efficiency, and compared with manual feeding, the support is convenient and the supporting effect is good. It solves the existing problem that the removal of the shaped tail b of the silicon rod generally adopts the method of manually inserting a wedge block under the shaped tail b, and then cutting the shaped tail b after padding the shaped conical surface. In addition, the feeding of the shaped tail b after cutting is also carried out manually, which not only reduces the work efficiency, but also increases the labor intensity, involves many people, and leads to the technical problem of increased cost of cutting the silicon rod.

[0087] An automatic unloading method for a silicon rod with a special-shaped tail, the automatic unloading method comprising the following steps:

[0088] S1. Start the material discharging body 1: The control body starts the material discharging body 1, so that the movable support 11 of the material discharging body 1 can move toward the tail end of the silicon rod along the length direction of the processing platform a under the drive of the travel motor, so as to drive the support body 2 to approach the tail end of the silicon rod.

[0089] S2. Stop the unloading body 1: When the supporting body 2 abuts against the end face of the silicon rod's tail end, the suction cup 2122 can adaptively control the distance between the suction cup 2122 and the special-shaped tail b under the adjustment of the horizontal adjustment guide rod 2121, so that the suction cup 2122 can abut against the special-shaped tail b, with a larger contact area, thereby improving the supporting effect, and then the unloading body 1 is controlled to stop moving through the control body.

[0090] S3. Support body adsorption: The suction cup 2122 of the adsorption unit 212 of the support body 2 adsorbs and fixes the special-shaped tail portion b at the tail end of the silicon rod.

[0091] S4, cutting the special-shaped tail: the control body controls the cutting head c to cut the special-shaped tail b fixed in step S3.

[0092] S5, the support body 2 gives way: the control body controls the external air pump to stop working, so that the suction cup 2122 of the support body 2 is separated from the special-shaped tail b, so that the special-shaped tail b falls on the blanking body 1, and the support body 2 stops. After the support body 2 stops, it forms a synchronous movement with the blanking body 1.

[0093] S6. Transportation of special-shaped tail: The control body controls the moving support 11 of the unloading body 1 to move along the length direction of the processing platform a toward the tail end away from the silicon rod, so as to drive the special-shaped tail b on the receiving cylinder 132 on the unloading body 1 in step S5 to move to the unloading position and grab it into the waste collection box through the robot.
