Description

Technical Field

[0001] This utility model relates to the field of semiconductor packaging and testing technology, and more specifically, to a reel anti-reverse mounting device for a reel placement shaft. Background Technology

[0002] In the semiconductor packaging and testing phase, reels are used to carry, protect, and transport semiconductor components. These components are typically placed on the reels in a certain arrangement, and the reels are mounted on the reel placement shaft of the machine. The reel placement shaft is used to drive the reel to retract the tape, so that the semiconductor components are packaged into the tape for subsequent sorting, transportation, and use.

[0003] It should be noted that in the semiconductor industry, reels have a disc-shaped structure, and the outer circumference of the reel is used to carry semiconductor components, such as... Figure 2 and Figure 3 As shown, the front of the reel is flat, and the back of the reel has multiple grooves evenly arranged around the central axis of the reel as a foolproof design to facilitate the workers to distinguish and thus standardize the installation of the reel. The specific installation specifications require that the front of the reel face outward (i.e., away from the machine) and the back of the reel face inward (i.e., facing the machine).

[0004] However, during the installation of the reel, on-site workers may easily install the reel backwards due to a lack of knowledge of the standard installation method, fatigue, or distraction. Even if the front of the reel is facing inwards and the back is facing outwards, this incorrect installation will cause the tape to wind 180 degrees in a way that is not normal. This will result in abnormalities in the direction of the tape, the index holes, the product, and the printing on the reel, which will seriously affect production efficiency, cause delays in production schedules, and increase production costs.

[0005] Therefore, how to prevent the reel from being installed backwards is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] In view of this, the purpose of this utility model is to provide a reel anti-reverse installation device for a reel placement shaft, which can prevent workers from installing the reel in reverse and reduce reliance on the workers' installation experience.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A reel anti-reverse mounting device for a reel placement shaft includes:

[0009] A reel placement shaft includes a base and a positioning shaft passing through the base, wherein an elastic positioning element is inserted into the side wall of the positioning shaft and is movable along an axis perpendicular to the positioning shaft.

[0010] A detection pin is used to fit into a groove on the back of the reel. The first end of the detection pin is located inside the base and is elastically connected to the base. The second end extends out of the base and along the axial direction of the positioning shaft. The second end of the detection pin extends beyond the portion of the elastic positioning member located outside the base.

[0011] A locking block is disposed on the inner sidewall opposite to the positioning shaft and the elastic positioning member and is movable along the axial direction of the positioning shaft;

[0012] A linkage component is disposed between the detection needle and the locking block. When the detection needle is under pressure, the linkage component drives the locking block to move below the elastic positioning component to hold the elastic positioning component in place.

[0013] Preferably, there are multiple detection needles, which are evenly arranged around the positioning axis.

[0014] Preferably, the first end of the detection needle is coaxially connected to a spring fixing rod, the spring fixing rod is disposed through the side wall of the base facing away from the elastic positioning member, and the spring fixing rod is sleeved with a first elastic member that abuts against the base and the first end of the detection needle.

[0015] Preferably, the elastic positioning element includes a positioning piece and a second elastic element. The bottom of the positioning piece passes through the wall slot of the positioning shaft and is inserted into the interior of the positioning shaft. The bottom of the positioning piece is connected to the inner sidewall of the positioning shaft opposite to the wall slot through the second elastic element. The positioning piece has an elongated hole that extends along the axial direction perpendicular to the positioning shaft and is slidably inserted into a limiting rod inside the positioning shaft.

[0016] Preferably, the end of the positioning piece facing away from the base has a ramp that slopes toward the base.

[0017] Preferably, the linkage includes a connecting rod, which is rotatably disposed inside the base. The first end of the connecting rod is rotatably connected to the detection needle, and the second end is inserted into the interior of the positioning shaft and rotatably connected to the locking block. When the detection needle is in a non-pressurized state, the connecting rod is tilted toward the elastic positioning member, and the locking block is located beside the elastic positioning member.

[0018] Preferably, there are multiple connecting rods, each corresponding to one of the multiple detection pins, and at least one locking block is provided, with one locking block connecting one, two, or more connecting rods.

[0019] Preferably, the linkage component includes:

[0020] A detection needle sensor is located inside the base and adjacent to the detection needle, and is used to monitor whether the detection needle is under pressure in real time and transmit the signal to the control system.

[0021] A driver, located inside the positioning shaft and with its output shaft connected to the locking block, is used to signal-connect the control system to control the movement of the locking block.

[0022] Preferably, the base is provided with a first proximity sensor, which is located near the detection needle and is used to monitor whether the detection needle is under pressure in real time and transmit the signal to the alarm.

[0023] Preferably, a second proximity sensor is provided inside the positioning shaft, and the second proximity sensor is located adjacent to the locking block for real-time monitoring of whether the locking block moves and transmitting a signal to the alarm.

[0024] The reel anti-reverse installation device for the reel placement shaft provided by this utility model has the following advantages: When the reel is installed facing forward (back side facing the base on the positioning shaft), the detection pin can be embedded in the groove on the back of the reel. In this case, the detection pin is not pressed and will not move the locking block below the elastic positioning element via the linkage. The elastic positioning element can then be pressed into the positioning shaft, allowing the reel to be installed on the positioning shaft. However, if the reel is installed backward (front side facing the base on the positioning shaft), the detection pin will be pressed against the base. The detection pin, via the linkage, will move the locking block below the elastic positioning element and press against it, preventing the elastic positioning element from being pressed into the positioning shaft, thus preventing the reel from being installed on the positioning shaft. Therefore, even if on-site personnel are unfamiliar with the standard installation method, are fatigued, or are distracted, this device can prevent the reel from being installed backward, reducing reliance on the installation experience of the personnel and thus avoiding delays in production schedules and increased production costs.

[0037] 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.

[0038] The core of this utility model is to provide a reel anti-reverse installation device for a reel placement shaft. This device can prevent workers from installing the reel 1 in reverse, reducing reliance on workers' installation experience.

[0039] Please refer to Figure 7 This utility model provides a specific embodiment of a reel anti-reverse installation device for a reel placement shaft, including a reel placement shaft 2, a detection pin 3, a locking block 4, and a linkage component.

[0040] In this embodiment, please refer to Figure 4 and Figure 5 The reel placement shaft 2 includes a base 21 and a positioning shaft 22 that passes through the base 21. An elastic positioning element 23 that is movable along the axial direction of the vertical positioning shaft 22 is inserted into the side wall of the positioning shaft 22.

[0041] It should be noted that the reel placement shaft 2 mainly includes a base 21 and a positioning shaft 22. The base 21 is mounted on the housing of the packaging equipment. The positioning shaft 22 extends through the base 21 into the interior of the housing and connects to a drive assembly. The drive assembly is used to rotate the positioning shaft 22, thereby rotating the reel 1 mounted on the positioning shaft 22. Figure 1 As shown.

[0042] Please refer to Figure 3 and Figure 5 The positioning shaft 22 is located on the side wall outside the housing, and an elastic positioning member 23 is inserted therein. Specifically, the side wall of the positioning shaft 22 is provided with a wall slit, the bottom of the elastic positioning member 23 passes through the wall slit and is inserted into the interior of the positioning shaft 22, and the top of the elastic positioning member 23 is located outside the positioning shaft 22, and is used to engage with the limiting hole 12 on the reel 1 to position the reel 1.

[0043] Furthermore, the elastic positioning member 23 is axially movable along the vertical positioning shaft 22. Since the elastic positioning member 23 is elastic, when installing the reel 1, the reel 1 can press part of the elastic positioning member 23 into the interior of the positioning shaft 22, ensuring that the reel 1 can be sleeved on the positioning shaft 22 along the axial direction of the positioning shaft 22. After the reel 1 is installed in place, the part of the elastic positioning member 23 outside the base 21 (i.e., the top of the elastic positioning member 23) engages with the limiting hole 12 on the reel 1. Thus, if the elastic positioning member 23 is not pressed into the positioning shaft 22, it will prevent the reel 1 from being sleeved on the positioning shaft 22, making it impossible to install the reel 1.

[0044] In this embodiment, please refer to Figure 3 and Figure 5 The detection needle 3 is used to fit into the groove 11 on the back of the reel 1. The first end of the detection needle 3 is located inside the base 21 and is elastically connected to the base 21, and the second end extends out of the base 21.

[0045] It should be noted that the main function of the detection needle 3 is to detect the installation direction of the reel 1. The specific detection logic is based on the difference between the front and back of the reel 1. As described in the background technology above, the back of the reel 1 has a groove 11. The length of the detection needle 3 extending into the interior of the base 21 can be adjusted according to the depth of the groove 11 so that the detection needle 3 fits properly into the groove 11. If the reel 1 is installed in the forward direction, that is, the back of the reel 1 faces the base 21 and is installed on the positioning shaft 22, the detection needle 3 can be embedded in the groove 11 on the back of the reel 1, and the detection needle 3 is not under pressure. If the reel 1 is installed in the reverse direction, that is, the front of the reel 1 faces the base 21 and is installed on the positioning shaft 22, the front of the reel 1 will press the detection needle 3 against the base 21. Therefore, the installation direction of the reel 1 can be detected by whether the detection needle 3 is under pressure.

[0046] It should also be noted that, please refer to Figure 7Along the axial direction of the positioning shaft 22, the second end of the detection needle 3 extends beyond the portion of the elastic positioning member 23 located outside the base 21. In other words, the second end of the detection needle 3 needs to extend beyond the top of the elastic positioning member 23 along the axial direction of the positioning shaft 22 to ensure that the reel 1 contacts the detection needle 3 first when installing it. This way, if the reel 1 is installed backwards, the detection needle 3 can promptly detect that the reel 1 is installed incorrectly and prevent the elastic positioning member 23 from moving downwards. This also promptly reminds the operator to reel the reel 1, avoiding excessive mounting of the reel 1 on the positioning shaft 22 and increasing the difficulty of removing and adjusting the reel 1.

[0047] In one specific embodiment, please refer to Figure 7 The detection needle 3 extends axially along the positioning shaft 22. It is understood that the reel 1 is coaxially fitted with the positioning shaft 22, allowing the reel 1 to move axially along the positioning shaft 22 during installation, and the detection needle 3 extends axially along the positioning shaft 22. Therefore, if the reel 1 is installed backwards, the detection needle 3 can be guaranteed to bear the axial pressure, thus avoiding uneven force on the detection needle 3 and preventing eccentricity or bending effects, thereby preventing damage to the detection needle 3 and preventing deformation of the detection needle 3 that could damage the reel 1.

[0048] In this embodiment, please refer to Figure 7 The locking block 4 is located on the inner wall of the positioning shaft 22 opposite to the elastic positioning member 23 and is movable along the axial direction of the positioning shaft 22. That is, the locking block 4 is located inside the positioning shaft 22 and is movable along the axial direction of the positioning shaft 22, positioned below the elastic positioning member 23. As described above, if the elastic positioning member 23 is not pressed into the positioning shaft 22, it will prevent the reel 1 from being fitted onto the positioning shaft 22. Therefore, a linkage is provided between the detection needle 3 and the locking block 4 to link them. When the detection needle 3 is under pressure, it can determine that the reel 1 is installed backwards. The detection needle 3 can then link the locking block 4 through the linkage, controlling the locking block 4 to move axially along the positioning shaft 22, positioned below the elastic positioning member 23, thus preventing the reel 1 from being fitted onto the positioning shaft 22.

[0049] In summary, the reel anti-reverse installation device for the reel placement shaft provided in the above embodiments features a linkage design between the detection pin 3 and the locking block 4. The detection pin 3 can detect the orientation of the reel 1. When the detection pin 3 detects that the reel 1 is installed in reverse, the detection pin 3 controls the locking block 4 to press against the elastic positioning member 23 through the linkage, preventing the elastic positioning member 23 from being pressed into the positioning shaft 22, thus preventing the reel 1 from being installed on the positioning shaft 22. Therefore, even if on-site personnel are not familiar with the standard installation method, are fatigued, or are distracted, this device can prevent the reel 1 from being installed in reverse, reducing reliance on the installation experience of the personnel, thereby avoiding delays in production schedules and increased production costs.

[0050] Based on the above embodiments, please refer to Figure 5Multiple detection needles 3 are provided, and the multiple detection needles 3 are evenly arranged around the axial direction of the positioning shaft 22.

[0051] As can be understood from the above description, the detection pin 3 can detect the installation direction of the reel 1. Multiple detection pins 3 are evenly arranged around the axial direction of the positioning shaft 22, which can cover a larger area of ​​the reel 1. As long as the reel 1 touches any one of the detection pins 3, it can be said that the reel 1 is installed incorrectly, so that the detection pin 3 can promptly link with the locking block 4 to press against the elastic positioning element 23, thereby preventing the reel 1 from being fitted onto the positioning shaft 22 in time, and improving the reliability of the device in preventing the reel 1 from being installed backwards.

[0052] It should be noted that, please refer to Figure 3 The back of the existing reel 1 is generally provided with at least three grooves 11, and the number of detection pins 3 should be consistent with the number of grooves 11 to ensure that each detection pin 3 is embedded in the corresponding groove 11, so as to avoid obstructing the reel 1 from being installed in the forward direction on the positioning shaft 22.

[0053] Based on the above embodiments, please refer to Figure 7 The first end of the detection needle 3 is coaxially connected to the spring fixing rod 6. The spring fixing rod 6 passes through the side wall of the base 21 facing away from the elastic positioning member 23, and the spring fixing rod 6 is sleeved with a first elastic member 7 that abuts against the base 21 and the first end of the detection needle 3.

[0054] Specifically, the outer side wall of the base 21 faces outwards from the inside of the housing and is used to abut against the reel 1. The inner side wall of the base 21 faces inwards from the housing and is used to fix and connect to the housing. The base 21 is a hollow shell. The inner and outer side walls of the base 21 are respectively provided with a first through hole and a second through hole. The spring fixing rod 6 passes through the first through hole and is inserted into the interior of the base 21 and coaxially connected to the first end of the detection needle 3. The head of the spring fixing rod 6 located outside the base 21 is fastened to the base 21 by fasteners (e.g., nuts). The second end of the detection needle 3 passes through the second through hole and extends outwards from the interior of the base 21 to abut against the front of the reel 1 or be embedded in the back of the reel 1. The spring fixing rod 6 is fitted with a first elastic element 7 that abuts against the base 21 and the first end of the detection needle 3. In this way, when the detection needle 3 is pressed, the detection needle 3 can press against the base 21 through the elastic deformation of the first elastic element 7, which compensates for the displacement of the detection needle 3 toward the base 21, so as to buffer the pressure of the front of the reel 1 on the detection needle 3 and avoid damage to the reel 1. Moreover, when the reel 1 is removed, the detection needle 3 can be quickly reset under the reset action of the first elastic element 7, without the need for manual reset, which can improve the operation efficiency.

[0055] In addition, it should be noted that since the head of the spring fixing rod 6 extends through the inner wall of the base 21 and out of the interior of the base 21, the detection needle 3 can be moved by manually pulling the head of the spring fixing rod 6, thereby adjusting the length of the detection needle 3 extending out of the interior of the base 21, which is more suitable for reels 1 with different groove depths 11.

[0056] Based on the above embodiments, please refer to Figure 7 The elastic positioning element 23 includes a positioning piece 231 and a second elastic element 232. The bottom of the positioning piece 231 passes through the wall gap of the positioning shaft 22 and is inserted into the interior of the positioning shaft 22. The bottom of the positioning piece 231 is connected to the inner side wall of the positioning shaft 22 opposite to the wall gap through the second elastic element 232.

[0057] Specifically, the side wall of the positioning shaft 22 has a wall slot extending axially along the positioning shaft 22. The positioning piece 231 passes through the wall slot and is inserted into the interior of the positioning shaft 22. A second elastic element 232 is provided between the inner side wall of the positioning shaft 22 opposite to the wall slot and the positioning piece 231. In its natural state, the end of the positioning piece 231 facing away from the elastic element (i.e., the top of the positioning piece 231) protrudes from the interior of the positioning shaft 22. Thus, during the installation of the reel 1, the reel 1 will press down on the positioning piece 231, and the second elastic piece will compress and deform, compensating for the downward displacement of the positioning piece 231. After the reel 1 is installed in place, the top of the positioning piece 231 can lock into the limiting hole 12 on the reel 1, realizing the installation of the reel 1. In addition, during the disassembly and assembly of the reel 1, it can be quickly reset by the reset action of the second elastic element 232, eliminating the need for manual reset, which facilitates subsequent installation of the reel 1 and improves operational efficiency.

[0058] Further, please refer to Figure 7 The positioning piece 231 has an elongated hole 8, which extends axially along the vertical positioning shaft 22 and slides into the limiting rod 9 inside the positioning shaft 22. Thus, the sliding engagement of the elongated hole 8 and the limiting rod 9 not only restricts the axial displacement of the positioning piece 231 along the positioning shaft 22, preventing the positioning piece 231 from shifting, but also allows the positioning piece 231 to be partially pressed into the positioning shaft 22 when under pressure, preventing the positioning piece 231 from jamming with the reel 1.

[0059] In one specific embodiment, both the first elastic element 7 and the second elastic element 232 are springs with strong elastic restoring force and simple structure. Of course, the two elastic elements can also be other types, such as air cushion elastic elements or torsion bar springs, depending on the specific configuration, and are not the only options.

[0060] Based on the above embodiments, please refer to Figure 7The positioning piece 231 has a ramp at the end facing away from the base 21 that is inclined toward the base 21. In this way, the ramp can not only guide the reel 1 to be inserted along the axial direction of the positioning shaft 22 to ensure accurate alignment when installing the reel 1, but also prevent the detection needle 3 from contacting the reel 1 before it is installed when calibrating the direction of the reel 1, thus preventing the detection needle 3 from failing to detect the positive and negative directions of the reel 1.

[0061] For details regarding the specific configuration of the linkage components, please refer to the first specific embodiment. Figure 6 and Figure 7 The linkage includes a connecting rod 5, which is rotatably located inside the base 21. The first end of the connecting rod 5 is rotatably connected to the detection needle 3, and the second end is inserted into the interior of the positioning shaft 22 and rotatably connected to the locking block 4. When the detection needle 3 is in a non-pressurized state, the connecting rod 5 is tilted toward the elastic positioning member 23, and the locking block 4 is located on the side of the elastic positioning member 23.

[0062] Specifically, the first end of the connecting rod 5 is hinged to the part of the detection needle 3 inserted into the base 21 via a pin, and the second end of the connecting rod 5 passes through the wall gap of the positioning shaft 22 and is inserted into the interior of the positioning shaft 22. The second end of the connecting rod 5 is also hinged to the locking block 4 via a pin. When the detection needle 3 is in a non-pressurized state, that is, in a natural state, the first end of the connecting rod 5 is positioned closer to the elastic positioning member 23 relative to its second end. Even if the connecting rod 5 is tilted towards the elastic positioning member 23, the locking block 4 is located on the side of the elastic positioning member, ensuring that the elastic positioning member 23 can perform a downward action when the detection needle 3 is not pressed.

[0063] When the above structure is used to install reel 1, if reel 1 is installed in reverse, the detection pin 3 will push the first end of the connecting rod 5 away from the elastic positioning member 23, and the second end of the connecting rod 5 will move towards the elastic positioning member 23. This will cause the locking block 4 to move below the elastic positioning member 23, thus locking the elastic positioning member 23 and preventing it from being pressed down. Consequently, reel 1 cannot be installed on the positioning shaft 22, and the on-site personnel can realize that reel 1 is installed incorrectly and reinstall it. After the pressure of the detection pin 3 disappears, the detection pin 3 will move back to its original position, causing the first end of the connecting rod 5 to move towards the elastic positioning member 23. At the same time, the second end of the connecting rod 5 will move the locking block 4 away from the elastic positioning member 23, and the locking block 4 will reset, releasing the locking of the elastic positioning member 23 and ensuring the normal installation of reel 1 in the future. Therefore, the connecting rod 5 with the above-described structure can link the detection pin 3 and the locking block 4, thereby preventing reel 1 from being installed in reverse.

[0064] It is understandable that the link 5 has the advantages of high load-bearing capacity, good stability and simple structure. Moreover, in this embodiment, the detection element and the locking block 4 are located inside the base 21 and the positioning shaft 22, respectively. The use of the link 5 can ensure smooth power transmission while being compactly arranged and saving space. Furthermore, it can link the detection needle 3 and the locking block 4 without relying on external control signals or power input, so that the movement of the detection needle 3 and the locking block 4 is fully driven by the link 5.

[0065] It should also be noted that this device has two extreme operating conditions: First, when installing reel 1, reel 1 first contacts the elastic positioning element 23; second, the locking block 4 fails to move and cannot move below the elastic positioning element 23. However, in the face of these two extreme operating conditions, the detection needle 3 will be locked and cannot move, and reel 1 still cannot be installed on the positioning shaft 22. The specific reasons are as follows:

[0066] When the elastic positioning element 23 is pressed down, the locking block 4 is blocked from moving below the elastic positioning element 23, and consequently the connecting rod 5 cannot move. The detection needle 3 is locked and cannot press against the base 21. The detection needle 3 will abut against the front of the reel 1 to prevent the reel 1 from being installed on the positioning shaft 22. Similarly, if the locking block 4 fails to move, the detection needle 3 is also locked and cannot press against the base 21. The detection needle 3 can still prevent the reel 1 from being installed on the positioning shaft 22. Therefore, this device can prevent the reel 1 from being installed backwards even under extreme working conditions, greatly improving the stability and reliability of the device.

[0067] Regarding the number of connecting rods 5, detection pins 3, and locking blocks 4, the number of connecting rods 5 must be consistent with the number of detection pins 3, and the number of both can be selectively set according to actual needs. In addition, at least one locking block 4 must be set, and one, two, or more connecting rods 5 can be linked to one locking block 4.

[0068] In this specific embodiment, a first proximity sensor is provided inside the base 21. The first proximity sensor is located near the detection needle 3 and is used to monitor in real time whether the detection needle 3 is under pressure and transmit the signal to the alarm.

[0069] Specifically, the first proximity sensor is located inside the base 21 and near the detection needle 3. If the detection needle 3 is pressed and moves, the first proximity sensor can detect the movement of the detection needle 3, that is, the detection needle 3 is pressed at this time, and send a pressure signal to the alarm. It should be noted that the alarm is located near the packaging equipment or directly installed on the packaging equipment. After receiving the movement signal of the detection needle 3, the alarm will sound an alarm, thereby timely and effectively alerting the on-site staff that the reel 1 is installed incorrectly. This can prevent the staff from continuously pushing the reel 1 in reverse and damaging the locked elastic positioning member 23.

[0070] In one specific embodiment, the first proximity sensor is an inductive sensor, and the first elastic element 7 is a spring. The inductive sensor is disposed adjacent to the spring and determines the position of the spring by sensing changes in current, thereby monitoring whether the detection needle 3 has moved.

[0071] In this specific embodiment, a second proximity sensor is provided inside the positioning shaft 22. The second proximity sensor is located near the locking block 4 and is used to monitor whether the locking block 4 moves in real time and transmit the signal to the alarm.

[0072] Specifically, the second proximity sensor is set inside the positioning shaft 22 and adjacent to the initial position of the locking block 4. It should be noted that the initial position of the locking block 4 refers to the position of the locking block 4 next to the elastic positioning member 23 when the detection needle 3 is in a non-pressurized state. The second proximity sensor can monitor whether the locking block 4 moves in real time. If the locking block 4 fails and cannot move (i.e., the second extreme working condition described above), the second proximity sensor will send a locking block 4 fault signal to the alarm, and the alarm will sound an alarm, thereby timely and effectively reminding the on-site personnel to check and maintain the locking block 4 to ensure the normal operation of the device in the future.

[0073] In one specific embodiment, the second proximity sensor is a capacitive sensor, in which case the locking block 4 is selected as a non-metallic locking block 4; or, the second proximity sensor is an inductive sensor, in which case the locking block 4 is selected as a metallic locking block 4. The designer can choose to set these options.

[0074] In this specific embodiment, a photoelectric sensor is provided on the side wall of the base 21 facing the elastic positioning member 23, which is used to monitor in real time whether the reel 1 is installed in place and transmit the signal to the alarm.

[0075] It is understandable that the reel 1 is mounted on the positioning shaft 22 and abuts against the base 21. If the reel 1 is not installed in place, the photoelectric sensor will not receive the light signal and will send a signal to the alarm. After receiving the signal, the alarm will sound an alarm, which can remind the on-site staff that the reel 1 is not installed in place, so as to avoid the risk of the packaging equipment operating due to the reel 1 not being installed in place.

[0076] It should be noted that the packaging equipment has a control system, which can use complex logic to control the various components of the packaging equipment in a coordinated manner, thereby achieving intelligent automatic control. Therefore, the aforementioned first proximity sensor, second proximity sensor, and photoelectric sensor can all be connected to the alarm via control system signals.

[0077] Regarding the specific configuration of the linkage, in the second specific embodiment, the detection needle sensor is located inside the base 21 and adjacent to the detection needle 3, and is used to monitor in real time whether the detection needle 3 is under pressure and transmit the signal to the control system; the driver is located inside the positioning shaft 22 and its output shaft is connected to the locking block 4. The driver is used to signal connect to the control system to control the movement of the locking block 4.

[0078] Specifically, the detection needle sensor is located inside the base 21 and adjacent to the detection needle 3. If the detection needle 3 is pressed and moves, the detection needle sensor can detect the movement, indicating that the detection needle 3 is under pressure, and sends a pressure signal to the control system. The control system then controls the driver to move below the elastic positioning member 23 to hold it in place. The elastic positioning member 23 is locked and cannot be pressed down, thus preventing the reel 1 from being installed on the positioning shaft 22. Therefore, the detection needle sensor and driver with the above-described linkage can link the detection needle 3 and the locking block 4, thereby preventing the reel 1 from being installed backwards.

[0079] Furthermore, it should be noted that link 5 is limited by the cumulative error of hinge clearance, resulting in a lag in dynamic response and lower accuracy. The detection needle sensor and the actuator work together to link detection needle 3 and locking block 4, directly transmitting power and precisely controlling the displacement and speed of locking block 4 with a small error range.

[0080] In this specific embodiment, the first proximity sensor, the second proximity sensor, and the photoelectric sensor with the above-described structure can still be provided.
