Technical Field

[0001] The utility model relates to the technical field of semiconductor production, in particular to an automatic bag breaking and material discharging device. Background Art

[0002] Silicon material is the raw material of the semiconductor industry and the photovoltaic industry. Usually, silicon material is transported and stored in material bags. Before preparing silicon crystals, the material bags need to be opened or a leaking hole needs to be opened on the material bags in order to pour out the silicon material in the material bags. Manually opening the material bags is not only inefficient and labor-intensive, but also harmful to the health of workers. There are some automated devices for breaking and dumping material bags. Such devices use cutting tools to pierce and cut the material bags to form a leaking hole. The breaking method of cutting the material bags with cutting tools has the following problems: it is difficult for the cutting tool to cut a double-layer material bag, the posture and shape of the material bag make it difficult for the cutting tool to concentrate pressure on the surface of the material bag, and the cutting tool is damaged and blunted when it contacts the silicon material. The existence of the above problems makes it inconvenient to cut the material bag with a cutting tool and it is difficult to form a leaking hole. Utility Model Content

[0003] In view of this, the utility model aims to solve the problem that it is inconvenient to cut the material bag with a cutting tool and it is difficult to form a leakage hole, and provides an automatic bag breaking and material pouring device that can efficiently and easily form a leakage hole for smoothly pouring silicon material.

[0004] The automatic bag breaking and material discharging device provided by the utility model comprises:

[0005] The placing mechanism includes a placing piece, and the position and posture of the placing piece includes a loading position for the placing piece to obtain a material bag and a dumping position for the placing piece to dump materials;

[0006] An irradiation unit, used for irradiating the material bag carried on the storage device to form a leakage hole;

[0007] The posture changing mechanism drives and connects the placement mechanism, and is used to drive the placement piece to change its posture at least between a loading posture and a dumping posture.

[0008] The automatic bag breaking and material unloading device of the utility model has the following beneficial effects: an irradiation unit is used to replace the cutting tool in the existing similar devices, and the irradiation unit irradiates the material bag so that the surface of the material bag absorbs the energy in the light emitted by the irradiation unit, thereby causing the surface of the material bag to melt or vaporize to form a breach for material leakage, thereby realizing the breach of the material bag in an irradiation manner without physical contact with the material bag, thereby improving the convenience of the material bag breaching process and reducing the difficulty of breaching, and there is no problem of the cutting tool being damaged and blunted, thereby reducing the cutting efficiency or difficulty in forming a breach for material leakage.

[0009] In one embodiment, the storage part is a storage bin, and a pouring port is provided on the side of the storage bin. The pouring port is located on the side of the storage bin close to the irradiation unit when the storage bin is in a loading position, and is located on the side of the storage bin close to the ground when the storage bin is in a dumping position. With such a configuration, when the storage bin is in a loading position, the light emitted by the irradiation unit can pass through the pouring port into the storage bin to irradiate the bag, and when the storage bin is in a dumping position, the material in the bag can be dumped out from the pouring port. The position of the storage part is set reasonably, which is convenient for the implementation of the bag breaking step and the pouring step, and the bag breaking step and the pouring step are connected in sequence, which helps to shorten the rhythm of bag breaking and pouring.

[0010] In one embodiment, the storage bin is further provided with an input port, which is located on a side of the storage bin away from the ground when the storage bin is in a loading position. With such a configuration, the input port facilitates the storage bin to obtain material bags.

[0011] In one embodiment, the storage bin includes a push portion disposed opposite to the side portion where the material discharge port is located, and the automatic bag breaking and material discharge device also includes a blocking portion. When the storage bin is in a load position, the blocking portion is located between the push portion and the irradiation unit, and a bag clamping interval for accommodating material bags is formed between the blocking portion and the push portion. With such an arrangement, the material bags accommodated in the bag clamping interval can be irradiated by the irradiation unit when the storage bin is in a load position, and the material bags are clamped by the blocking portion and the push portion to form a leakage opening that meets the expectations.

[0012] In one embodiment, the push portion is movably arranged relative to the side where the material discharge port is located, and can be close to the blocking portion to reduce the width of the bag clamping interval when the storage bin is in a loaded position. In this way, the push portion and the blocking portion can cooperate to fully clamp the material bag, ensuring that the material bag is irradiated by the irradiation unit in a static state.

[0013] In one embodiment, when the storage bin is in the loading position, the push portion and the blocking portion are arranged in parallel. In this way, the pressure exerted on the bag by the push portion and the blocking portion is balanced, which is conducive to maintaining the stability and balance of the bag in the bag clamping interval, thereby facilitating the formation of a leaking hole that meets the expectations under the irradiation of the irradiation unit.

[0014] In one embodiment, the blocking portion is provided with a light-through opening, which is connected to the bag-clamping interval when the storage bin is in a loading position to allow the irradiation unit to emit light to the bag-clamping interval. In this way, when the storage bin is in a loading position and the blocking portion and the push portion clamp the bag in the bag-clamping interval, the light emitted by the irradiation unit can pass through the light-through opening and the pouring opening to irradiate the bag, thereby taking into account both the clamping of the bag and the irradiation of the bag.

[0015] In one embodiment, the blocking portion is provided with a light-through opening, which is connected to the bag-clamping interval when the storage bin is in a loading position, and the light-through opening is any one or more of a U-shaped opening, a V-shaped opening, an L-shaped opening, a T-shaped opening, and an X-shaped opening. In this way, the cross-sectional shape of the light beam passing through the light-through opening is any one or more of a U-shaped, a V-shaped, an L-shaped, a T-shaped, and an X-shaped. When the material bag is irradiated by the light beam, a strip-shaped hot-melt area in any one or more of a U-shaped, a V-shaped, an L-shaped, a T-shaped, and an X-shaped strip can be formed. Under the pressure of the material, the material bag expands to form a leaking opening, and when the material is dumped, no residual fragments of the material bag will be mixed into the material.

[0016] In one embodiment, the automatic bag breaking and unloading device further includes a shifting mechanism, the shifting mechanism includes a shifting part that can move along a preset shifting trajectory, and the number of the placing mechanisms is multiple, wherein: the multiple placing mechanisms are arranged in sequence along the preset shifting trajectory, the irradiation unit is arranged in the shifting part, and the irradiation unit is located at the side of the queue formed by the multiple placing mechanisms; or, the multiple placing mechanisms are arranged in the shifting part, and the multiple placing mechanisms are arranged in sequence along the preset shifting trajectory, and the irradiation unit is arranged at the side of the queue formed by the multiple placing mechanisms. With such an arrangement, the irradiation unit can move and shift relative to the queue formed by the multiple placing mechanisms along the extension direction of the preset shifting trajectory, thereby irradiating the openings of the multiple bags one by one and in an orderly manner, which is suitable for efficient opening and unloading operations of batch bags, and also reduces the number of irradiation units.

[0017] In one embodiment, the displacement mechanism further includes a bearing part and a sliding guide part provided on the bearing part, the displacement part and the sliding guide part are slidably connected, and the displacement part slides along the sliding guide part to form a preset displacement track. With such a configuration, the displacement of the irradiation unit along the preset displacement track relative to the queue formed by the plurality of placement mechanisms is easier to achieve, and the movement track and movement direction are more accurate, so that the irradiation unit can more accurately irradiate the bags in each placement mechanism one by one.

[0018] In one embodiment, the irradiation unit is arranged in the displacement part, and the automatic bag breaking and material discharging device further comprises a blocking part arranged in the displacement part, and the blocking part is used to limit and fix the material bags respectively carried on the multiple storage parts one by one by the blocking part. In this way, the blocking part can move and change position along the preset displacement track together with the irradiation unit, so that the blocking part cooperates with the irradiation unit to ensure that the material bags in each storage part can be irradiated in the state of being limited and fixed, so as to form the expected leakage opening by hot melting, and the number of blocking parts is correspondingly reduced.

[0019] In one embodiment, the blocking portion is movably disposed on the displacement portion, and the blocking portion can move at an angle relative to the extension direction of the sliding guide portion so that the blocking portion stops the material bag. In this way, the blocking portion can prevent the material bag from falling out of the storage bin, which can better meet actual use requirements.

[0020] In one embodiment, the storage mechanism further includes a bag-beating execution unit and a bag-beating driving unit. The bag-beating execution unit is movably arranged on the storage unit, and the bag-beating driving unit is connected to the bag-beating execution unit to drive the bag-beating execution unit to reciprocate. With such a configuration, the bag-beating driving unit can drive the bag-beating execution unit to simulate a manual bag-beating action to repeatedly beat the material bag, thereby discharging the residual material in the material bag, thereby reducing material waste.

[0021] In one embodiment, the automatic bag breaking and material discharging device further includes a material receiving bin, which is arranged on the side of the storage unit close to the ground and has a material receiving opening open to the storage unit, and the irradiation unit includes a laser generator. In this arrangement, the laser emitted by the laser generator has high energy, and after the laser is irradiated to the material bag, a hot melting area can be formed in a very short time, so that the material bag has a leakage opening, thereby significantly improving the efficiency of the bag opening.

[0022] In one embodiment, the storage mechanism further includes a sensor, the sensor is used to sense whether the storage part carries a bag, and the posture changing mechanism is connected to the sensor in communication with the irradiation unit.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0030] At present, many types of industrial raw materials are transported and stored in bags. For example, silicon materials used in the semiconductor industry and the photovoltaic industry, granular or powdered silicon materials are usually packed in bags with double-layer membranes. Before preparing silicon crystals, the bags need to be opened or a leaking hole needs to be opened on the bags to pour out the silicon materials from the bags. The utility model provides an automatic bag breaking and pouring device 100 that can automatically break and pour the material in the bag. The leaking hole is formed on the bag by the automatic bag breaking and pouring device 100.

[0031] In some embodiments, the automatic bag breaking and material discharging device 100 of the present invention is used to automatically break and discharge a bag containing silicon material. In other embodiments, the automatic bag breaking and material discharging device 100 of the present invention can also automatically break and discharge a bag containing other raw materials. The automatic bag breaking and material discharging device 100 of the present invention is described below by taking the breaking and material discharging operation of a bag containing silicon material as an example.

[0032] See also Figure 1 The automatic bag breaking and material unloading device 100 of the utility model at least includes a placing mechanism 10, an irradiation unit 20 and a posture changing mechanism 30. The placing mechanism 10 includes a placing part 11, and the placing part 11 has a plurality of posture states, including a loading posture for the placing part 11 to obtain a material bag and a dumping posture for the placing part 11 to dump materials. The irradiation unit 20 can generate light and irradiate the material bag with the light to form a material leakage opening in the material bag. The posture changing mechanism 30 is driven and connected to the placing mechanism 10, and is used to drive the posture of the placing part 11 to change at least between a loading posture and a dumping posture.

[0033] Specifically, the material bag obtained when the object placement part 11 is in the loading position is a material bag filled with silicon material and intact, the irradiation unit 20 can irradiate the material bag when the object placement part 11 is in the loading position, and can also irradiate the material bag when the object placement part 11 is in the dumping position, and the posture changing mechanism 30 can drive the object placement part 11 to switch back and forth between the loading position and the dumping position, so that the automatic bag breaking and material dumping device 100 can break and dump the batches of material bags one by one.

[0034] In some embodiments, the irradiation unit 20 irradiates the material bag when the placement piece 11 is in the loading position, and the posture changing mechanism 30 drives the placement mechanism 10 to operate after the irradiation unit 20 completes irradiation of the material bag, so that the posture of the placement piece 11 is switched from the loading position to the dumping position, and after the silicon material in the material bag is dumped, the posture changing mechanism 30 drives the placement mechanism 10 again, so that the posture of the placement piece 11 is switched from the dumping position to the loading position again to prepare for receiving the next material bag.

[0035] In some embodiments, the automatic bag breaking and material pouring device 100 further includes a material receiving bin 50 for collecting the material poured out from the material bag. Figure 1 The receiving bin 50 is a hollow container with a receiving opening 51, and the receiving bin 50 is arranged on a side of the placement member 11 relatively close to the ground, and the receiving opening 51 is open to the placement member 11. When the irradiation unit 20 completes irradiation of the material bag and the placement member 11 is in a dumping position, the silicon material in the material bag passes through the receiving opening 51 under the action of gravity and falls into the receiving bin 50.

[0036] In some embodiments, the storage element 11 is a storage compartment 110, see Figure 2 and Figure 3The storage bin 110 includes a plate-shaped bin bottom 113, and also includes a first side plate 116 and a second side plate 117 respectively connected to two opposite edges of the bin bottom 113, and a push portion 114 connected to the other edge of the bin bottom 113. The first side plate 116, the second side plate 117 and the push portion 114 all protrude relative to one side of the bin bottom 113. The first side plate 116 and the second side plate 117 are arranged to face each other and spaced apart so that a storage area for accommodating material bags is formed therebetween. The push portion 114 connects the first side plate 116 and the second side plate 117. The storage bin 110 as a whole is similar to a dustpan-shaped structure.

[0037] Furthermore, a pouring port 111 is opened on the side of the storage bin 110, and an input port 112 is opened on the top of the storage bin 110. The pouring port 111 is used for pouring materials in the material bag located in the storage bin 110 to leave the storage bin 110, and the input port 112 allows the material bag containing the material to be put into the storage bin 110. Figure 1 The storage bin 110 shown in the upper middle part is in a loaded position, and the storage bin 110 shown in the lower middle part is in a dumped position. Figure 2 and Figure 3 When the storage bin 110 is in a loading position, the pouring port 111 is located on a side of the storage bin 110 close to the irradiation unit 20, and the input port 112 is located on a side of the storage bin 110 away from the ground. At this time, the material bags in the storage bin 110 can be irradiated by the irradiation unit 20. When the storage bin 110 is in a dumping position, the pouring port 111 is located on a side of the storage bin 110 close to the ground.

[0038] Specifically, see Figure 1 , see also Figure 2 and Figure 3 In some embodiments, the posture changing mechanism 30 includes a posture changing driver 31 and a posture changing rocker arm 32. The posture changing driver 31 may be a motor capable of outputting torque. One end of the posture changing rocker arm 32 is connected to the output shaft of the posture changing driver 31, and the other end is connected to the storage bin 110. After the posture changing driver 31 is started, the posture changing rocker arm 32 is driven to rotate through the output shaft, and the posture changing rocker arm 32 drives the storage bin 110 to rotate, so that the storage bin 110 changes its posture. Optionally, the bin bottom 113 is horizontally arranged when the storage bin 110 is in a loading posture, and is vertically arranged when the storage bin 110 is in a dumping posture.

[0039] It can be understood that in other embodiments, the posture changing mechanism 30 can also adopt other forms of power source and transmission component combinations. For example, the posture changing driver 31 can be a push rod motor or a cylinder that can output linear displacement, and the posture changing mechanism 30 also includes a rack and pinion mechanism. The push rod motor or the cylinder is connected to the rack, and the conversion of linear power into torque power is realized through the rack and pinion mechanism. The storage bin 110 is connected to the gear, and as the gear is driven by the rack, it rotates to change the posture.

[0040] Figure 1 to Figure 3 In the illustrated embodiment, when the storage bin 110 is in the loading position, the input port 112 is vertically opened upward, and when the storage bin 110 is in the dumping position, the pouring port 111 is vertically opened downward, and the pouring port 111 is now opened opposite to the receiving port 51. If the side where the pouring port 111 is located is defined as the pouring side of the storage bin 110, the push portion 114 is disposed opposite to the pouring side, the pouring port 111 is formed by the first side plate 116, the second side plate 117 and the bin bottom 113, and the input port 112 is formed by the first side plate 116, the second side plate 117 and the push portion 114.

[0041] In some embodiments, the irradiation unit 20 includes a laser generator 21, which can emit a laser for irradiating the material bag. The irradiated position of the material bag absorbs the energy of the laser and heats up and melts to form a hot-melt area. The pressure of the silicon material on the inner wall of the material bag forces the hot-melt area to break, thereby forming a leakage rupture.

[0042] In some embodiments, the storage mechanism 10 also includes a sensor, which is used to sense whether there is a material bag in the storage part 11, and can generate a material bag in place signal when the storage part 11 carries a material bag. The irradiation unit 20 and the posture change mechanism 30 are both connected to the sensor through an industrial control network or a control unit. The irradiation unit 20 can be started and illuminated according to the in-place signal, and the posture change mechanism 30 can be started according to the in-place signal and drive the storage bin 110 to switch to a dumping position.

[0043] Furthermore, the sensor can also sense whether the material bag carried by the storage unit 11 contains silicon material, and can generate a clear signal after the material bag carried by the storage unit 11 has dumped the silicon material therein. The clear signal indicates that the material bag in the current storage unit 11 has completed the breaking and dumping operations, and the storage unit 11 can prepare for the next material bag to be broken and dumped. The posture change mechanism 30 operates again according to the clear signal and drives the storage bin 110 to switch from the dumping position to the loading position again.

[0044] Optionally, the sensor can be / include a through-light sensor disposed in the storage bin 110, or can be / include a pressure sensor disposed in the storage bin 110. The through-light sensor can form a through-light between the first side plate 116 and the second side plate 117 for sensing whether a material bag exists, and the pressure sensor can be disposed at the bin bottom 113 to sense whether a material bag is placed in the storage bin 110.

[0045] In some embodiments, the storage mechanism 10 also includes a bag-slapping assembly 12, which includes a bag-slapping actuator 121 that is movably arranged relative to the object 11, and a bag-slapping driving unit 122 that is driven and connected to the bag-slapping actuator 121. The bag-slapping driving unit 122 can drive the bag-slapping actuator 121 to reciprocate relative to the object 11, thereby simulating the action of manually slapping the material bag, thereby replacing the manual slapping of the material bag to slap and discharge the residual material in the material bag, thereby improving the material collection rate and reducing material waste.

[0046] Figure 2-3 In the illustrated embodiment, the bag-beating driving unit 122 is a bag-beating cylinder fixedly mounted on the storage bin 110, and the bag-beating executing unit 121 includes a slapping plate and a top column connected to the bag-beating driving unit 122. The slapping plate is located in the storage area of ​​the storage bin 110 and can be driven by the bag-beating driving unit 122 to move. The top column passes through at least one or more of the first side plate 116, the second side plate 117 and the bin bottom 113. The top column can reciprocate under the drive of the bag-beating driving unit 122 to change the size of the top column extending into the storage area. With such a configuration, the storage bin 110 itself does not need to generate reciprocating motion, and only the bag-beating executing unit 121 needs to reciprocate and hit the bag.

[0047] In some embodiments, the automatic bag breaking and unloading device 100 further includes a shifting mechanism 40, which includes a bearing portion 41 and a shifting portion 43 that can be movably arranged on the bearing portion 41 along a preset shifting trajectory; the number of the placement mechanisms 10 is multiple, and the multiple placement mechanisms 10 are arranged in sequence along the extension direction of the preset shifting trajectory to form a queue; the irradiation unit 20 is arranged on the shifting portion 43 and is located at the side of the queue formed by the arrangement of the placement mechanisms 10. The irradiation unit 20 can move along the preset shifting trajectory following the shifting portion 43, so that the irradiation unit 20 can move through the sides of the multiple placement mechanisms 10 in sequence and in an orderly manner, so that only one irradiation unit 20 is required to irradiate and break the bags carried on the multiple placement mechanisms 10 one by one.

[0048] In some embodiments, the automatic bag breaking and unloading device 100 further includes a shifting mechanism 40, which includes a bearing portion 41 and a shifting portion 43 that can be movably disposed on the bearing portion 41 along a preset shifting trajectory; there are multiple placement mechanisms 10, and the multiple placement mechanisms 10 are all disposed on the shifting portion 43 and are sequentially arranged along the extension direction of the preset shifting trajectory to form a queue, and the irradiation unit 20 is located at the side of the queue formed by the arrangement of the multiple placement mechanisms 10. The multiple placement mechanisms 10 can follow the shifting portion 43 to move along the preset shifting trajectory, so that the irradiation unit 20 can pass through the sides of the multiple placement mechanisms 10 sequentially and orderly.

[0049] It can be understood that the preset displacement trajectory can be a straight line segment trajectory, a broken line trajectory formed by multiple straight line segments, or a curved trajectory.

[0050] Specifically, see Figure 1 and Figure 4 In some embodiments, the shift mechanism 40 further includes a bearing portion 41 and a sliding guide portion 42 disposed on the bearing portion 41. The sliding guide portion 42 may be a section of a guide rail or a section of a continuously extending strip groove. A sliding connection is formed between the shift portion 43 and the sliding guide portion 42. The sliding trajectory of the shift portion 43 along the sliding guide portion 42 is a preset shift trajectory. The irradiation unit 20 is disposed on the shift portion 43. A plurality of placement mechanisms 10 are sequentially arranged along the extension direction of the sliding guide portion 42 to form a queue, and the plurality of placement mechanisms 10 are fixed relative to the bearing portion 41. Figure 1 The middle arrow S indicates the extension direction of the preset shift trajectory.

[0051] It can be understood that in other embodiments, the shifting portion 43 can also be replaced by a conveyor belt, and accordingly the supporting portion 41 can be a frame of the conveyor line body, the sliding guide portion 42 can be a guide support table for supporting and guiding the conveyor belt, and the irradiation unit 20 is fixedly arranged on the conveyor belt and follows the conveyor belt to slide along the sliding guide portion 42 and pass through the placement mechanism 10 one by one.

[0052] Further, Figure 1 In the illustrated embodiment, there are multiple material receiving bins 50 , and the multiple material receiving bins 50 correspond one-to-one to the multiple storage mechanisms 10 , respectively. A corresponding material receiving bin 50 is disposed below the storage bin 110 of each storage mechanism 10 .

[0053] Optionally, in some embodiments, the queue formed by the plurality of placement mechanisms 10 and the irradiation unit 20 intermittently slide relative to each other along a preset displacement track. When the irradiation unit 20 and the placement mechanism 10 are relatively stationary, the irradiation unit 20 starts and emits light to the bag in one of the placement mechanisms 10, that is, at this time, the bag and the irradiation unit 20 are relatively stationary. After the irradiation of the bag in the previous placement mechanism 10 is completed, the irradiation unit 20 slides relative to the placement mechanism 10 until the irradiation unit 20 reaches the next rest position, and then the irradiation unit 20 starts again and emits light to the bag in the next placement mechanism 10.

[0054] With such arrangement, a certain area on the bag can receive the light from the irradiation unit 20 in a concentrated manner, thereby gathering heat, which is conducive to forming a hot-melt area in a shorter time, thereby accelerating the formation of a leaking hole in the bag.

[0055] In some embodiments, the automatic bag breaking and material discharging device 100 further includes a blocking portion 44. When the storage unit 11 is in a loading position, the blocking portion 44 can stop the material bag carried on the storage unit 11, so that the material bag is irradiated by the irradiation unit 20 in a static and fixed state relative to the storage unit 11 and the irradiation unit 20. Figure 1 , Figure 1 The storage bin 110 shown in the upper middle portion is in a loading position, and the irradiation unit 20 is in a resting state relatively still with respect to the storage bin 110. The light emitting end of the irradiation unit 20 is aligned with the pouring port 111 of the storage bin 110. At this time, there is at least one blocking portion 44 between the push portion 114 and the irradiation unit 20, and a bag clamping interval 115 is formed between the blocking portion 44 and the push portion 114, and the bag clamping interval 115 is used to accommodate a bag containing silicon material.

[0056] Optionally, the bag compartment 115 includes a storage area of ​​the storage compartment 110. Preferably, Figure 1 In the illustrated embodiment, the blocking portion 44 covers the pouring port 111 of the storage bin 110 shown above in the figure, and the bag clamping interval 115 is the storage area of ​​the storage bin 110. At this time, the push portion 114 and the blocking portion 44 are parallel to each other, and the two can clamp the bag stably and evenly.

[0057] Further, see again Figure 1 and Figure 4 The blocking portion 44 is provided with a light opening 441. When the blocking portion 44 is stationary relative to one of the storage bins 110 and the blocking portion 44 is located between the push portion 114 of the storage bin 110 and the irradiation unit 20, the light opening 441 is connected to the bag clamping interval 115, that is, the light opening 441 is connected to the storage area of ​​the storage bin 110 at this time, and the light emitted by the irradiation unit 20 can pass through the light opening 441 and directly irradiate the bag located between the blocking portion 44 and the push portion 114.

[0058] Optionally, the light opening 441 is a strip-shaped opening, and the shape of the light opening 441 can be any one or more of a U-shape, a V-shape, an L-shape, a T-shape, and an X-shape. In this configuration, the light from the irradiation unit 20 will form a U-shape, a V-shape, an L-shape, a T-shape, or an X-shape hot-melt area on the surface of the material bag. When the material bag is subjected to the pressure of the silicon material, the material bag will form a larger area of ​​leakage rupture, and the material bag will not disintegrate, which can prevent the material bag fragments from being mixed in the silicon material.

[0059] Furthermore, in some embodiments, the blocking portion 44 is disposed on the displacement portion 43, and as the displacement portion 43 slides relative to the bearing portion 41 along the sliding guide portion 42, the blocking portion 44 and the irradiation unit 20 can slide along a preset displacement trajectory. Therefore, only one blocking portion 44 may be provided, and the blocking portion 44 can sequentially limit and stop the bags in the plurality of storage bins 110. Figure 1 and Figure 4 In the illustrated embodiment, the blocking portion 44 is movably disposed on the displacement portion 43 . On the one hand, the blocking portion 44 can slide along a preset displacement trajectory following the displacement portion 43 , and on the other hand, it can move along a trajectory set at an angle relative to the extension direction of the sliding guide portion 42 .

[0060] Specifically, see Figure 1 The shifting mechanism 40 also includes a blocking guide portion 45 arranged on the shifting portion 43, and a sliding connection is formed between the blocking portion 44 and the blocking guide portion 45. The extension direction of the blocking guide portion 45 intersects with the extension direction of the sliding guide portion 42, so that the blocking portion 44 can approach or move away from the queue formed by the multiple placement mechanisms 10 along the blocking guide portion 45. When the blocking portion 44 approaches the queue formed by the placement mechanisms 10, the blocking portion 44 can approach the push portion 114 of the placement bin 110 to increase the stopping force exerted on the bag. Conversely, when the blocking portion 44 moves away from the queue formed by the placement mechanisms 10, the stopping force exerted on the bag is reduced.

[0061] Preferably, the extending direction of the blocking guide portion 45 is perpendicular to the extending direction of the sliding guide portion 42, and the light beam emitted by the irradiation unit 20 is a straight light beam perpendicular to the sliding guide portion 42. In this way, whether the blocking guide portion 45 is close to or far away from the queue formed by the placement mechanism 10, it does not affect the light emitted by the irradiation unit 20 passing through the light opening 441.

[0062] In some embodiments, the push portion 114 is movably arranged relative to the side where the pouring port 111 is located. The push portion 114 can be close to the blocking portion 44 when the storage bin 110 is in a loading position, and the width of the bag clamping interval 115 is reduced. The push portion 114 and the blocking portion 44 are arranged in this way to cooperate with each other to clamp the bag, so as to ensure that the bag is irradiated by the irradiation unit 20 in a static state, thereby forming a leakage breach as quickly as possible.

[0063] In some embodiments, the automatic bag breaking and material pouring device 100 further includes an adsorption unit, which includes a suction cup 118 and a vacuum generator connected to the suction cup 118. The suction cup 118 is located in the storage bin 110 and is used to adsorb the material bag containing silicon material. When the material bag is put into the storage bin 110, the vacuum generator is activated to form a negative pressure. At this time, the suction cup 118 adsorbs the material bag to limit the material bag from sliding relative to the storage bin. When the storage bin 110 is in the dumping position, the suction cup 118 continues to maintain the adsorption force on the material bag to ensure that the material bag will not fall out of the storage bin 110 while the silicon material is poured out.

[0064] Preferably, the suction cup 118 is relatively fixed to the storage bin 110 .
