Description

Technical Field

[0001] This utility model relates to the field of semiconductor cutting and processing technology, and more specifically, to an automatic film-tearable iron ring storage and transportation device. Background Technology

[0002] Semiconductor dicing refers to the process of cutting a pre-encapsulated frame containing multiple semiconductors into individual semiconductors during semiconductor manufacturing. This process determines the final size, shape, and quality of the semiconductor.

[0003] The existing semiconductor cutting and forming process is as follows: First, the frame is attached to a thin film (such as a UV film) and mounted on an iron ring. Then, the semiconductor is cut and formed. After cutting, the semiconductor is peeled off from the thin film. Then, the film needs to be manually peeled off, that is, the iron ring and the film are manually separated. The film is placed in the waste film recycling bin in the film peeling area, and the iron ring is placed in the temporary storage box in the film peeling area. When the iron ring is needed in the film application area, the temporary storage box is manually moved to the film application area so that the iron ring can be used in the next production.

[0004] It should be noted that manual film removal is suitable for small-scale production. Although it is low-cost and flexible, the semiconductor cutting and forming process described above has the following problems as production scales up: 1. Low efficiency: Manual film tearing is slow and has low production efficiency, making it unsuitable for large-scale production.

[0005] 2. High labor intensity: Operators need to manually tear the film frequently for a long time, which is time-consuming and laborious, and can easily lead to the risk of hand joint diseases.

[0006] 3. Safety hazards exist: There is a risk that the iron ring may slip and injure the feet during the manual tearing process.

[0007] In conclusion, how to improve production efficiency, reduce manual labor intensity, and lower safety hazards are problems that urgently need to be solved by those skilled in the art. Utility Model Content

[0008] In view of this, the purpose of this utility model is to provide an automatic film-tearing iron ring storage and transportation device, which can improve production efficiency, reduce manual labor intensity and reduce safety hazards.

The iron ring frame has a through-hole so that the film on the iron ring can communicate with the interior of the waste film storage bin. A film-tearing mechanism is located between the iron ring frame and the first end of the waste film storage bin along the length direction, and is used to cut the film on the iron ring so that it falls into the interior of the waste film storage bin. An iron ring storage bin is arranged along the length of the waste film storage bin and adjacent to the first end. The top end of the iron ring storage bin is an open end and is not higher than the top end of the waste film storage bin in the height direction.

[0016] Preferably, the film-tearing mechanism includes: Beam frame; Two cutting components are arranged along the width direction of the waste film storage bin with a gap between them. The gap is equal to the maximum width of the film on the iron ring. The cutting components are rotatable on the beam frame around the width direction of the waste film storage bin. When the cutting components are in a vertical state, their bottoms extend into the waste film storage bin to cut the iron ring and the film downwards.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] The core of this utility model is to provide an automatic film-tearable iron ring storage and transportation device, which can improve production efficiency, reduce manual labor intensity and reduce safety hazards.

[0026] Please refer to Figure 1 and Figure 5 This application provides an automatic film-tearing iron ring storage and transportation device, including a waste film storage bin 1, a film-tearing mechanism 5, an iron ring storage bin 6, and a drive mechanism 7.

[0027] The top of the waste film storage bin 1 is an open end and is provided with an iron ring frame 2 for placing the iron ring 3. The iron ring frame 2 has a through opening so that the film 4 on the iron ring 3 can communicate with the interior of the waste film storage bin 1.

[0028] The film-tearing mechanism 5 is located between the iron ring frame 2 and the first end 16 of the waste film storage bin 1 in the length direction, and is used to cut the film 4 on the iron ring 3 so that it falls into the interior of the waste film storage bin 1.

[0029] The iron ring storage bin 6 is arranged along the length of the waste film storage bin 1 and is adjacent to the first end 16. The top of the iron ring storage bin 6 is an open end and is not higher than the top of the waste film storage bin 1 in the height direction.

[0030] The drive end of the drive mechanism 7 is used to push the iron ring 3 through the film-tearing mechanism 5 into the iron ring storage bin 6.

[0031] Specifically, the waste film storage bin 1 is used to support the iron ring 3 of the film to be torn and collect the film 4. The top of the waste film storage bin 1 is an open end and is equipped with an iron ring frame 2. The iron ring frame 2 can support the iron ring 3 of the film to be torn on the top of the waste film storage bin 1, and the iron ring frame 2 has a through-hole that allows the film 4 on the iron ring 3 of the film to be torn to connect with the interior of the waste film storage bin 1, so as to ensure that the film 4 cut by the film tearing mechanism 5 falls into the interior of the waste film storage bin 1 through the through-hole, thereby realizing the collection of the film 4. Preferably, the maximum width of the through-hole is not less than the maximum width of the film 4, so as to avoid the frame of the iron frame from obstructing the film 4 from falling.

[0032] The film-tearing mechanism 5 can be a cutter or have a cutter assembly. There is a notch 15 between the iron ring frame 2 and the first end 16 of the waste film storage bin 1 in the length direction. The film-tearing mechanism 5 is located in the notch 15. Thus, when the iron ring 3 to be peeled moves through the notch 15, as the iron ring 3 continues to move toward the iron ring storage bin 6, the film-tearing mechanism 5 can gradually cut the film 4 on the iron ring 3 to be peeled until it falls into the waste film storage bin 1.

[0033] The iron ring storage bin 6 is placed adjacent to the first end 16 of the waste film storage bin 1 along its length. The top of the iron ring storage bin 6 is an open end and cannot be higher than the top of the waste film storage bin 1, so that the iron rings 3 that have been torn off can fall naturally into the iron ring storage bin 6 to achieve the collection of the iron rings 3.

[0034] The drive mechanism 7 can be a motor, which is located on the side of the second end in the length direction. The output shaft of the motor is set along the length direction of the waste film storage bin 1. When the iron ring 3 to be peeled is placed on the iron ring frame 2, the output shaft of the motor can abut against the iron ring 3 to push the iron ring 3 through the film peeling mechanism 5 into the iron ring storage bin 6.

[0035] Therefore, the automatic film-tearing iron ring storage and transportation device provided in the above embodiment integrates film tearing, waste film collection, and iron ring 3 storage into one unit. When used in the film-tearing area, there is no need for manual film tearing, waste film collection, or iron ring 3 storage, which can improve production efficiency, reduce labor intensity, and reduce safety hazards. It should be noted that after a batch of iron rings 3 has been peeled, the iron ring storage bin 6 is then transported to the film-applying area, and the iron rings 3 can be used for the next production cycle.

[0036] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 and Figure 3 The automatic film-tearing iron ring storage and transportation device also includes a workbench 17, with an open top and a hollow interior. A partition 8 is provided between the two side walls of the workbench 17 in the width direction, dividing the workbench 17 along its length to form a waste film storage bin 1 and an iron ring storage bin 6. The second end of the iron ring frame 2 and the waste film storage bin 1 in the length direction has no gaps. The drive mechanism 7 is located near the second end of the waste film storage bin 1 in the length direction of the iron ring frame 2. In this way, the drive mechanism 7, waste film storage bin 1, film-tearing mechanism 5, and iron ring storage bin 6 are all centrally located on the workbench 17, which not only saves space and facilitates unified management of the components but also makes it easier to move the device and adjust its position.

[0037] Preferably, the waste film storage chamber 1 has a removable collection box nested inside, which facilitates the subsequent cleaning of waste film.

[0038] To avoid manually moving the iron ring 3 to the film-applying area for the next production run, the first embodiment is preferred based on the above embodiments. Please refer to the following: Figure 1 Casters 10 are provided at the four corners of the bottom of the workbench 17, and a handle 11 is provided on one outer side wall of the workbench 17.

[0039] In this way, when the film application area needs to use the iron ring 3, the device can be pushed directly to the film application area and then the iron ring 3 can be picked up. That is, the movable workbench 17 is used to replace manual labor to transport the iron ring 3 to the film application area. This not only avoids the risk of falling and injuring feet during the manual handling of a large number of iron rings 3, further reducing safety hazards, but also the movable workbench 17 is more time-saving and labor-saving, further reducing the intensity of manual labor and improving production efficiency, making it better suited for large-scale production.

[0040] The caster 10 is preferably a swivel caster, which can rotate freely 360 degrees, allowing the workbench 17 to move flexibly during travel for easy handling.

[0041] The iron rings 3 that have had their film removed are collected in the iron ring storage bin 6. For easy retrieval of the iron rings 3, please refer to the following in the first embodiment: Figure 1 The iron ring storage compartment 6 has vertical through holes 9 on both sides of its width direction, with the two through holes 9 facing each other. In this way, the operator can see the number of iron rings 3 through the through holes 9, and can also manually clamp the iron rings 3 upwards through the two facing through holes, thereby improving the convenience of picking up the iron rings 3.

[0042] It should be noted that existing semiconductor processing equipment has a film-applying area, a cutting area, and a film-peeling area on its production line. The film-applying area is equipped with a semiconductor film-applying device for bonding the thin film 4 and the semiconductor frame together and mounting them onto the iron ring 3. The cutting area is equipped with a semiconductor cutting device, whose inlet is connected to the outlet of the semiconductor film-applying device, for cutting and peeling the semiconductor mounted on the iron ring 3. The automatic film-peeling iron ring storage and transportation device of this invention has the functions of film peeling, waste film collection, iron ring 3 storage, and transportation, and can be applied to the film-peeling area.

[0043] To further optimize and reduce manual labor intensity and improve production efficiency, in the first embodiment, as a further preferred option, the automatic film-tearing iron ring storage and transportation device also includes two six-degree-of-freedom robotic arms. One robotic arm is used to pick up the iron ring 3 at the outlet of the semiconductor cutting device and place it onto the iron ring frame 2, and the other robotic arm is used to pick up the iron ring 3 in the iron ring storage bin 6 and place it at the inlet of the semiconductor film-applying device.

[0044] Understandably, a six-degree-of-freedom robotic arm can move flexibly in space and can replace manual labor on semiconductor production lines to place iron rings 3 to be peeled off and pick up iron rings 3 that have been peeled off, greatly improving production efficiency and reducing the intensity of manual labor.

[0045] Furthermore, in the first embodiment, as a further preferred embodiment, the automatic film-tearable iron ring storage and transportation device also includes a controller, a positioning sensor, and a counting sensor. The positioning sensor is located on the iron ring frame 2 and is used to detect whether there is an iron ring 3 on the iron ring frame 2. The counting sensor is located in the iron ring storage bin 6 and is used to detect the number of iron rings 3 in the iron ring storage bin 6. The controller signal is connected to the positioning sensor, the counting sensor, the drive mechanism 7, and the two robotic arms.

[0046] In this way, the first robotic arm places the iron ring 3, which is to be peeled off, from the outlet of the semiconductor cutting device onto the iron ring frame 2. The positioning sensor detects the iron ring 3 and sends a positioning signal to the controller. After receiving the positioning signal, the controller sends an open command to the drive mechanism 7. The drive mechanism 7 pushes the iron ring 3 through the film peeling mechanism 5 into the iron ring storage bin 6, thus completing the film peeling. Then, the positioning sensor can no longer detect the iron ring 3 and sends a vacancy signal to the controller. After receiving the vacancy signal, the controller sends a pick-up command to the first robotic arm. The first robotic arm will then place the next iron ring 3, which is to be peeled off, from the outlet of the semiconductor cutting device onto the iron ring frame 2, and repeat the above film peeling process. At the same time, the counting sensor will detect the number of iron rings 3 in the iron ring storage bin 6 in real time and transmit it to the controller. When the number of iron rings 3 reaches a preset number, the controller sends a pick-up command to the second robotic arm. The second robotic arm will then place a batch of iron rings 3 from the iron ring storage bin 6 to the inlet of the semiconductor film application device, and then reset to prepare for picking up the next batch of iron rings 3. Therefore, by adopting the above settings, manual intervention can be reduced, automated iron ring 3 film-tearing and transportation operations can be realized, production efficiency can be significantly improved, and it is suitable for automated production lines.

[0047] It should be noted that the weight of the iron ring 3 is generally around 245g. When the iron rings 3 fall into the iron ring storage chamber 6 one by one, they will collide and deform. In addition, if the depth of the iron ring storage chamber 6 is too deep, the iron rings 3 will be more severely damaged when they fall in. Therefore, the depth of the existing iron ring storage chamber 6 is generally 100mm, and it can hold a maximum of 40 iron rings 3 with a thickness of 2.5mm.

[0048] To optimize the storage method of the iron ring storage bin 6, in the first embodiment, as a further preferred option, please refer to... Figure 3 The iron ring storage chamber 6 is equipped with a platform 12 that is elastically connected to its bottom end. The platform 12 can move up and down to adjust the space for the iron ring 3 formed between the platform 12 and the top of the iron ring storage chamber 6.

[0049] It is understandable that the platform 12 and the bottom of the storage compartment for the iron ring 3 are elastically connected. That is, the two are dynamically connected through an elastic element. When the platform 12 is loaded, the elastic element will be pressed down and deformed, and the platform 12 will move downward. When the load on the platform 12 decreases or disappears, the elastic element will rebound upward, and the platform 12 will move upward. In this way, the iron ring 3 that has completed the film removal is pushed onto the platform 12 by the drive mechanism 7. Each time the platform 12 receives an iron ring 3, it descends one height, gradually moving away from the opening end of the iron ring storage compartment 6. This allows the platform 12 to automatically adjust the size of the iron ring 3 accommodating space according to the number of iron rings 3 it carries. That is, as the number of iron rings 3 increases, the accommodating space for the iron ring 3 also gradually increases.

[0050] The aforementioned platform 12 has the following advantages: First, when the iron ring 3 falls onto the platform 12, the platform 12 will descend, leaving space for subsequent iron rings 3 to fall into, thus avoiding collisions between the front and rear iron rings 3; Second, it reduces the falling height of the iron ring 3, preventing the iron ring 3 from falling directly into the bottom of the iron ring storage chamber 6 and deforming; Third, the iron ring 3 is supported by the platform 12, which can move up and down elastically, allowing for the use of a deep iron ring storage chamber 6, which can expand the capacity while reducing the deformation of the iron ring 3.

[0051] Regarding the specific elastic connection method between platform 12 and the bottom end of the iron ring storage bin 6, in the first embodiment, as a further preferred option, please refer to... Figure 3 The bottom of the iron ring storage chamber 6 is provided with four rectangular columns 13, which pass through the four corners of the platform 12. Each column 13 located between the platform 12 and the bottom of the iron ring storage chamber 6 is fitted with a spring 14. With this arrangement, the columns 13 can guide and position the platform 12 during its up and down movement, improving the stability of the platform 12's movement. Moreover, the fixed installation of the columns 13 provides strong rigidity, which can reduce the platform 12's offset or vibration, and improve the platform 12's load-bearing stability.

[0052] To avoid manually transporting the iron rings 3 to the film-applying area for the next production run, a second embodiment can be preferred based on the above embodiment. The automatic film-tearable iron ring storage and transportation device further includes a first conveyor belt mechanism and a second conveyor belt mechanism. The bottom end of the iron ring storage bin 6 is an open end. The first conveyor belt mechanism is used to be positioned between the discharge port of the semiconductor cutting device and the iron ring frame 2. The second conveyor belt mechanism is used to be positioned between the bottom end of the iron ring storage bin 6 and the inlet of the semiconductor film-applying device.

[0053] This setup allows the automatic film-peeling iron ring storage and transport device to be directly installed between the outlet of the semiconductor cutting device and the inlet of the semiconductor film-applying device (located in the film-applying area). The first conveyor belt mechanism can transport the iron ring 3 to be peeled at the outlet of the semiconductor cutting device to the iron ring frame 2. The iron ring 3 is peeled by the film-peeling mechanism 5 and falls into the iron ring 3 storage box. Since the bottom of the iron ring 3 storage box is an open end, the iron ring 3 that has been peeled can fall directly onto the second conveyor belt mechanism. The second conveyor belt mechanism can transport the iron ring 3 to the inlet of the semiconductor film-applying device.

[0054] Therefore, the first conveyor belt mechanism replaces manual picking of the iron ring 3 to be peeled, and the second conveyor belt mechanism replaces manual handling of the iron ring 3 after the film has been peeled. This not only saves labor and improves production efficiency, but is also more suitable for automated production lines.

[0055] In the second embodiment, both the first and second transport belt mechanisms adopt synchronous belt transport mechanisms, that is, synchronous belts are used to transport the iron ring 3. The specific structure of the synchronous belt transport mechanism can be referred to the prior art. Its structure is not the focus of this application and will not be described in detail here. It is only necessary to ensure that the synchronous belt in the first transport belt mechanism is located between the discharge port of the semiconductor cutting device and the iron ring frame 2, and the synchronous belt in the second transport belt mechanism is located between the bottom end of the iron ring 3 storage box and the inlet of the semiconductor film attaching device.

[0056] Furthermore, in the second embodiment, as a further preferred embodiment, the automatic film-tearing iron ring storage and transportation device also includes a controller and a positioning sensor. The positioning sensor is located on the iron ring frame 2 and is used to detect whether there is an iron ring 3 on the iron ring frame 2. The controller is signal-connected to the positioning sensor, the drive mechanism 7, the first conveyor belt mechanism, and the second conveyor belt mechanism. It should be noted that the controller is signal-connected to the host computer (equivalent to a computer control system) in the semiconductor processing equipment, and the host computer can control the start and stop of the automatic film-tearing iron ring storage and transportation device through signal transmission with the controller.

[0057] In this way, during semiconductor production line operation, the controller activates the first and second conveyor belt mechanisms, with their synchronous belts continuously operating. A batch of iron rings 3, awaiting film removal from the semiconductor dicing device, are transported one by one to the iron ring frame 2 via the synchronous belt in the first conveyor belt mechanism. A positioning sensor detects the iron ring 3 and sends a positioning signal to the controller. Upon receiving the positioning signal, the controller sends an activation command to the drive mechanism 7. The drive mechanism 7 pushes the iron ring 3 through the film-removing mechanism 5 into the iron ring storage bin 6, thus completing the film removal. The removed iron ring 3 then falls directly from the iron ring storage bin 6 onto the synchronous belt in the second conveyor belt mechanism, and is transported to the inlet of the semiconductor film-applying device. It should be noted that after the removed iron ring 3 leaves the iron ring frame 2, the next iron ring 3 awaiting film removal is transported to the iron ring frame 2 along with the synchronous belt, repeating the above steps. Therefore, this setup reduces manual intervention, automates the film removal and transportation of the iron rings 3, significantly improves production efficiency, and is suitable for automated production lines.

[0058] It should be noted that in both of the above embodiments, the positioning sensor can be an inductive sensor. The inductive sensor senses the presence of the iron ring 3 through a current coil in the probe. Its principle is to use a high-frequency electromagnetic field to sense the eddy current generated inside the iron ring 3, thereby detecting the presence of the iron ring 3. Moreover, in the first embodiment, the counting sensor can also be an inductive sensor. One method is to install the counting sensor at a preset depth inside the iron ring storage bin 6. This preset depth can be set according to the specified storage capacity of the iron ring 3. When the counting sensor senses the iron ring 3, it indicates that the number of iron rings 3 carried on the platform 12 has reached the requirement for one handling. Alternatively, the counting sensor can be installed at the top of the iron ring storage bin 6. When the iron ring 3 passes by the counting sensor, the counting sensor will sense the electromagnetic interference of the iron ring 3 and generate eddy currents, accurately identifying and counting the iron ring 3.

[0059] Regarding the specific configuration of the film-tearing mechanism 5, as a preferred embodiment based on the two embodiments described above, please refer to... Figures 2 to 6 The film-tearing mechanism 5 includes a beam frame 51, two cutting components 52, and at least one film-pulling hook 53.

[0060] Two cutting pieces 52 are arranged along the width direction of the waste film storage bin 1 with a gap between them. The gap is equal to the maximum width of the film 4 on the iron ring 3. The cutting pieces 52 can be rotated around the width direction of the waste film storage bin 1 and are mounted on the beam frame 51. When the cutting pieces 52 are in a vertical state, their bottoms extend into the waste film storage bin 1 to cut the iron ring 3 and the film 4 downwards.

[0061] At least one film-pulling hook 53 is provided on the inner sidewall of the first end 16 of the waste film storage bin 1 and near its top end, for pulling the film 4 into the waste film storage bin 1.

[0062] It should be pointed out that, as Figure 4 As shown, there is a gap 15 between the iron ring frame 2 and the first end 16 of the waste film storage bin 1 along its length. The beam frame 51 is erected directly above the gap 15, serving to fix and support the two cutting pieces 52. As mentioned above, the iron ring storage bin 6 is arranged along the length of the waste film storage bin 1. It is conceivable that the iron ring 3 falls into the iron ring storage bin 6 along the length of the waste film storage bin 1. Therefore, the two cutting pieces 52 are arranged along the width direction of the waste film storage bin 1 (perpendicular to the moving direction of the iron ring 3), and the distance between the two cutting pieces 52 is equal to the maximum width of the film 4, in order to ensure that the film 4 is completely detached from the iron ring 3.

[0063] Furthermore, when the cutting element 52 is in a vertical position, its bottom extends through the notch 15 into the waste film storage bin 1. This ensures that when the iron ring 3 passes by, the cutting element 52 will contact the film 4 on it and exert a downward cutting force on the film 4, thus ensuring that the cutting element 52 penetrates the film 4 for cutting. Further, the cutting element 52 can be rotated around the width direction of the waste film storage bin 1 (perpendicular to the direction of movement of the iron ring 3), which can prevent the cutting element 52 from obstructing the movement of the iron ring 3 and ensure the smooth movement of the iron ring 3.

[0064] Since the first end 16 of the waste film storage bin 1 is close to the iron ring storage bin 6, the first end 16 is equivalent to the outlet end of the iron ring 3. If a film-pulling hook 53 is installed on the inner side wall of the first end 16 of the waste film storage bin 1 and near its top, as the iron ring 3 moves toward the iron ring storage bin 6, the film-pulling hook 53 will hook the film 4 that has not completely fallen off. When the iron ring 3 is completely separated from the iron ring frame 2, the film-pulling hook 53 will completely pull the film 4 into the waste film storage bin 1, ensuring that the iron ring 3 and the film 4 are completely separated.

[0065] Therefore, the above-mentioned structure of the film-tearing mechanism 5 has the following advantages: First, it saves the internal space of the waste film storage bin 1; second, it can ensure that the iron ring 3 is completely separated from the film 4 while ensuring the smooth movement of the iron ring 3; third, it relies on the structural layout of the cutting component 52 and the film-pulling hook 53 to achieve cutting, without the need for a driver, which can reduce energy consumption.

[0066] Preferably, there are two or more film-pulling hooks 53. The multiple film-pulling hooks 53 are arranged at intervals and located between the two cutting pieces 52, which can effectively ensure that the iron ring 3 and the film 4 are completely separated.

[0067] Based on the above embodiments, as a further preferred option, please refer to... Figure 2 and Figure 4 The film-tearing mechanism 5 also includes two tension springs 54 that correspond one-to-one with the two cutting pieces 52. One end of the tension spring 54 is connected to the top of the cutting piece 52, and the other end is connected to the top side of the beam frame 51 away from the top of the iron ring frame 2.

[0068] To better explain the rotation direction of the cutting element 52, the arrangement of the waste film storage bin 1 and the iron ring storage bin 6 is illustrated from front to back. That is, the iron ring 3 moves towards the iron ring storage bin 6 along the length of the waste film storage bin 1, which means the iron ring 3 moves from front to back. During the process of the iron ring 3 passing through the film-tearing mechanism 5, the iron ring 3 abuts against the bottom of the cutting element 52 extending into the waste film storage bin 1 and rotates backward and upward. At the same time, the top of the cutting element 52 rotates forward and downward. The cutting element 52 will pull the tension spring 54, causing the tension spring 54 to deform. After the iron ring 3 has passed through the film-tearing mechanism 5, the cutting element 52 can automatically reset using the restoring force of the tension spring 54, ready to cut the next iron ring 3 to be peeled.

[0069] It should be noted that when the tension spring 54 is in its natural state (without any external force), the cutting piece 52 is in a vertical state, thus ensuring that the initial position of the cutting piece 52 is that its bottom extends into the waste film storage bin 1, thereby ensuring that the cutting piece 52 can abut against the film 4 on the iron ring 3 and cut downwards when the iron ring 3 passes by.

[0070] In one specific embodiment, please refer to Figure 4 Since the film 4 is relatively thin, the cutting part 52 can be a connecting rod. When the connecting rod abuts against the film 4, the film 4 cannot bear the weight of the connecting rod and falls downward.

[0071] In another specific embodiment, the cutting element 52 consists of a connecting rod and a blade located at its bottom, so that the film 4 can be cut using the blade, which is applicable to the cutting of most films 4 and better ensures that the iron ring 3 and the film 4 are completely separated.

[0072] Considering the specific connection method between the cutting component 52 and the beam frame 51, based on the above embodiment, the first implementation method is as follows, please refer to... Figure 2 The beam frame 51 includes an inverted U-shaped frame 511 and a rotating shaft 512. The two side plates of the inverted U-shaped frame 511 are respectively located on the two side walls of the waste film storage bin 1 in the width direction. The rotating shaft 512 is located between the two side plates of the inverted U-shaped frame 511 along the width direction of the waste film storage bin 1. Two cutting parts 52 are spaced apart on the rotating shaft 512, thereby realizing the rotational connection between the cutting parts 52 and the beam frame 51.

[0073] In the second embodiment, the beam frame 51 includes an inverted U-shaped frame 511 and two upright plates. The two side plates of the inverted U-shaped frame 511 are respectively located on the two side walls in the width direction of the waste film storage bin 1. The two upright plates are movably located on the top plate of the inverted U-shaped frame 511 along the width direction of the waste film storage bin 1, and two cutting pieces 52 are respectively installed on them. In this way, the upright plates can drive the cutting pieces 52 on them to move along the width direction of the waste film storage bin 1, thereby adjusting the distance between the two cutting pieces 52 to accommodate the cutting of films 4 of different sizes, improving the applicability of the film tearing mechanism 5.

[0074] The specific connection method between the upright plate and the top plate of the inverted U-shaped frame 511 is as follows: the bottom end of the top plate of the inverted U-shaped frame 511 is provided with a sliding groove and two actuators. The two actuators are located on both sides of the length direction of the top plate. The sliding groove extends along the width of the waste film storage bin 1. The top of each of the two upright plates is provided with a slider that is slidably embedded in the sliding groove. The two sliders are respectively connected to the output shafts of the two actuators. In this way, when it is necessary to adjust the distance between the two cutting pieces 52, the two actuators are turned on, and the two sliders are moved along the sliding groove. After the adjustment is completed, the two actuators are turned off. In this way, the film tearing mechanism 5 does not consume energy during the film tearing operation.

[0075] Furthermore, in the second embodiment, the specific connection between the upright plate and the cutting component 52 is as follows: the cutting component 52 is provided with a first mounting hole, the upright plate is provided with a second mounting hole, and the rotating shaft passes through the first mounting hole and the second mounting hole to fasten the cutting component 52 to the upright plate. The rotating shaft is arranged along the width direction of the waste film storage bin 1.

[0076] In summary, the automatic film-tearing iron ring storage and transportation device provided by this utility model has the following advantages: 1. The film-tearing mechanism 5 can automatically and completely separate the iron ring 3 and the film 4, replacing manual film tearing, reducing labor intensity and improving production efficiency.

[0077] 2. The film 4 can automatically fall into the waste film storage bin 1, and only periodic collection of waste film is required, which is convenient for management.

[0078] 3. It increases the storage capacity of the iron ring storage chamber 6, while preventing the iron ring 3 from falling into the iron ring storage chamber 6 and deforming.

[0079] 4. This avoids the need for manual handling of the iron ring 3 to the film application area.

[0080] In summary, the automatic film-tearing iron ring storage and transportation device provided by this utility model integrates film tearing, waste film collection, iron ring storage, and transportation into one unit, thereby improving production efficiency, reducing manual labor intensity, and reducing safety hazards.
