Description

Technical Field

[0001] This invention relates to the field of automatic tape-and-reel technology, and specifically to an automatic tape-and-reel device and method for crystal resonators. Background Technology

[0002] Existing technology discloses a continuous tape and reel equipment for electronic components and a method for achieving fully automatic continuous tape and reel production. The equipment includes: a support plane for component mounting; a support frame for the support plane; a multi-reel automatic winding mechanism located at the end of a carrier tape guide device; and a pre-winding mechanism for the covering film, a sealing tape feeding device, and a cutting mechanism disposed between the carrier tape guide device and the multi-reel automatic winding mechanism. The method mainly includes the following steps: 1) loading electronic components onto a carrier tape; 2) feeding the carrier tape into the carrier tape via a carrier tape feeding device; 3) guiding the carrier tape via a carrier tape guide device; 4) synchronously performing the transmission, heat-sealing, and winding of the carrier tape; 5) after heat-sealing to a set number, leaving an empty carrier tape and separating the covering film; 6) the pre-winding mechanism for the covering film quickly lifting and winding the pre-winding covering film; 7) cutting the carrier tape and rapidly winding the covering film onto the reel; 8) attaching tape to the end of the covering film; 9) cutting the tape, replacing with an empty reel, the end of the carrier tape entering the empty reel's hole, and the empty reel starting a new winding process. However, this method requires reserving a section of empty carrier tape without components when switching reels or completing packaging batches to meet process connection requirements, which leads to a significant increase in the ineffective consumption of carrier tape material and waste of resources. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic tape-and-reel device and method for crystal resonators, which solves the problem that existing continuous tape-and-reel equipment for electronic components and its fully automatic continuous tape-and-reel method require reserving a section of empty carrier tape without components when switching reels or completing packaging batches to meet process connection requirements, resulting in a significant increase in the ineffective consumption of carrier tape material and causing resource waste.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] In a first aspect, an automatic tape-making device for crystal resonators is provided, comprising a carrier tape conveying mechanism, a cutting mechanism, a guiding mechanism, a feeding channel, a reel mechanism, a detection mechanism, and a control mechanism. The cutting mechanism is disposed on the carrier tape conveying mechanism and is used to cut the heat-sealed carrier tape to obtain a carrier tape segment. The guiding mechanism is disposed at the discharge end of the carrier tape conveying mechanism. A plurality of feeding channels are arranged on the side of the guiding mechanism away from the carrier tape conveying mechanism. The reel mechanism is disposed on the side of the feeding channel away from the guiding mechanism, and the plurality of reel mechanisms correspond one-to-one with the feeding channels. The detection mechanism is used to generate a switching signal when it detects that the front end of the current carrier tape segment has reached the guiding mechanism and the rear end of the previous carrier tape segment has left the guiding mechanism. The control mechanism is used to control the guiding mechanism to guide the front end of the current carrier tape segment into the feeding channel corresponding to the reel mechanism of the receiving carrier tape segment when the switching signal is received.

[0006] A further solution is that the control mechanism is also used to increase the winding speed of the reel mechanism when the cutting mechanism cuts the heat-sealed cover tape of the carrier tape.

[0007] A further embodiment is as follows: several material conveying channels are evenly arranged around the conveying axis of the carrier belt on the carrier conveyor mechanism; the guiding mechanism includes a driving component and a guide tube; the guide tube is rotatably disposed at the discharge end of the carrier belt conveyor mechanism; the driving component is disposed at the discharge end of the carrier belt conveyor mechanism, and the driving component is connected to the guide tube and the control mechanism; wherein, the driving component is used to drive the guide tube to rotate around the conveying axis of the carrier belt on the carrier belt conveyor mechanism under the control of the control mechanism, so that the guide tube is connected to any one of the material conveying channels.

[0008] A further proposed solution is that the guide tube gradually moves away from the conveying axis of the carrier belt along the conveying direction of the carrier belt conveyor mechanism.

[0009] A further improvement is that the feed tube is made of a transparent material.

[0010] In a second aspect, an automatic tape-and-reel method for crystal resonators is provided, the method being applicable to the apparatus described in the first aspect, the method comprising the following operations:

[0011] The crystal resonators are placed sequentially into the receiving slots on the carrier tape;

[0012] The cover tape is heat-sealed onto the upper surface of the carrier tape that has been placed into the crystal resonator;

[0013] Count the number of crystal resonators that passed through the cutting mechanism;

[0014] When the number of crystal resonators reaches the preset value, the carrier tape is cut to form a carrier tape segment, and the count of the number of crystal resonators passing through the cutting mechanism is restarted.

[0015] Real-time acquisition of the position of the front end of the current carrier tape segment and the position of the rear end of the previous carrier tape segment;

[0016] When the front end of the current carrier tape segment arrives at the guide mechanism and the rear end of the previous carrier tape segment leaves the guide mechanism, the guide mechanism is controlled to move to guide the front end of the current carrier tape segment into the material conveying channel corresponding to the reel mechanism of the carrier tape segment to be received.

[0017] A further proposed solution is that the process of controlling the guide mechanism includes:

[0018] Obtain the number of material conveying channels;

[0019] The target rotation angle of the guiding mechanism is determined based on the number of material conveying channels;

[0020] The control guide mechanism rotates the target rotation angle along the preset rotation direction.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] The heat-sealed carrier tape is cut into segments using a cutting mechanism. When the rear end of the previous segment has left the guiding mechanism and the front end of the current segment has entered the guiding mechanism, a control mechanism guides the guiding mechanism to direct the front end of the current segment into the corresponding feeding channel of the reel mechanism receiving the next segment. The aim is to achieve precise cutting and guiding control, ensuring each carrier tape segment is connected end-to-end without requiring pre-reserved gaps, thereby significantly reducing material consumption of carrier tape and cover tape and minimizing resource waste.

Detailed Implementation

[0027] The invention will now be further described with reference to the accompanying drawings.

[0028] Example 1: This example provides an automatic tape-and-reel device for crystal resonators, such as... Figure 1 As shown, the system includes a carrier belt conveying mechanism 1, a cutting mechanism 2, a guiding mechanism 4, a material conveying channel 5, a reel mechanism 6, a detection mechanism 7, and a control mechanism 8. The cutting mechanism 2 is located on the carrier belt conveying mechanism 1 and is used to cut the heat-sealed carrier belt 3 to obtain a carrier belt segment. The guiding mechanism 4 is located at the discharge end of the carrier belt conveying mechanism 1. Several material conveying channels 5 are arranged on the side of the guiding mechanism 4 away from the carrier belt conveying mechanism 1. The reel mechanism 6 is located on the side of the material conveying channel 5 away from the guiding mechanism 4, and several reel mechanisms 6 correspond one-to-one with the material conveying channels 5. The detection mechanism 7 is used to generate a switching signal when it detects that the front end of the current carrier belt segment has reached the guiding mechanism 4 and the rear end of the previous carrier belt segment has left the guiding mechanism 4. The control mechanism 8 is used to control the guiding mechanism 4 to guide the front end of the current carrier belt segment into the material conveying channel 5 corresponding to the reel mechanism 6 that is to receive the carrier belt segment when the switching signal is received.

[0029] For example, in implementation, the automatic crystal resonator tape feeding device further includes a crystal resonator feeding mechanism 9, a cover tape heat sealing mechanism 10, and a counting mechanism 11. The crystal resonator feeding mechanism 9, the cover tape heat sealing mechanism 10, and the cutting mechanism 2 are all located above the carrier tape conveying mechanism 1, and are arranged sequentially from the inlet end to the outlet end of the carrier tape conveying mechanism 1. A guiding mechanism 4 is located at the outlet end of the carrier tape conveying mechanism 1. Several conveying channels 5 are provided, and these channels 5 are evenly distributed on the side of the guiding mechanism 4 away from the carrier tape conveying mechanism 1. A winding mechanism is located on the side of the conveying channel 5 away from the guiding mechanism 4, and several winding reel mechanisms 6 are provided, each corresponding to one of the conveying channels 5. In other words, the number of reel mechanisms 6 is the same as the number of feeding channels 5, and one reel mechanism 6 corresponds to one feeding channel 5. The reel mechanism 6 is used to receive the carrier tape segment output from the corresponding feeding channel 5. The control mechanism 8 is connected to the counting mechanism 11, the guiding mechanism 4, the cutting mechanism 2, and the detection mechanism 7.

[0030] During use, the carrier belt conveyor 1 conveys the carrier belt 3 along the direction from the feed end of the carrier belt conveyor 1 to the discharge end of the carrier belt conveyor 1.

[0031] As the carrier tape 3 passes below the crystal resonator feeding mechanism 9, the crystal resonator feeding mechanism 9 places the crystal resonator into the receiving slot on the carrier tape 3.

[0032] As the carrier tape conveyor 1 conveys the tape, the carrier tape 3 containing the crystal resonator is conveyed to the area below the cover tape heat sealing mechanism 10. At this time, the cover tape heat sealing mechanism 10 heat seals the cover tape onto the upper surface of the carrier tape 3 containing the crystal resonator.

[0033] As the carrier tape conveyor 1 conveys the tape, the heat-sealed cover tape 3 containing crystal resonators passes below the cutting mechanism 2, enters the guiding mechanism 4, and is guided into a feeding channel 5. The carrier tape 3 in the feeding channel 5 is gradually wound onto the corresponding reel mechanism 6. The winding speed of the reel mechanism 6 is the same as the conveying speed of the carrier tape conveyor 1. Simultaneously, as the front end of the heat-sealed cover tape 3 containing crystal resonators passes the cutting mechanism 2, the counting mechanism 11 begins to count the number of crystal resonators on the carrier tape 3 passing through the cutting mechanism 2. When the counted number of crystal resonators reaches a preset value (referring to the number of crystal resonators that need to be wound onto the reel mechanism 6), the control mechanism 8 controls the cutting mechanism 2 to cut the carrier tape 3, resulting in a carrier tape segment located on the side of the cutting mechanism 2 away from the heat-sealing cover tape mechanism 10. At this time, the carrier tape segment continues to be wound up under the action of the winding mechanism 6, and the counting mechanism 11 recounts the number of crystal resonators on the carrier tape 3 that has passed under the cutting mechanism 2 when the front end of the carrier tape 3 located on the side of the cutting mechanism 2 near the cover heat sealing mechanism 10 passes under the cutting mechanism 2. Among them, the carrier tape segment located on the side of the cutting mechanism 2 away from the cover heat sealing mechanism 10 is recorded as the previous carrier tape segment, and the carrier tape 3 located on the side of the cutting mechanism 2 near the cover heat sealing mechanism 10 is recorded as the current carrier tape segment.

[0034] Under the action of the reel mechanism 6, the rear end of the previous carrier belt segment (the end of the previous carrier belt segment closest to the current carrier belt segment) gradually passes through the guide mechanism 4 and leaves the guide mechanism 4, entering the material conveying channel 5. At the same time, under the conveying of the carrier belt conveyor mechanism 1, the front end of the current carrier belt segment (the end of the current carrier belt segment closest to the previous carrier belt segment) gradually enters the guide mechanism 4.

[0035] The detection mechanism 7 monitors the position of the rear end of the previous carrier tape segment and the position of the front end of the current carrier tape segment in real time. When the detection mechanism 7 detects that the rear end of the previous carrier tape segment has left the guide mechanism 4 and the front end of the current carrier tape segment has entered the guide mechanism 4, the detection mechanism 7 generates a switching signal.

[0036] When the control mechanism 8 receives the switching signal, it generates a control command.

[0037] The guiding mechanism 4 responds to the control command and performs corresponding actions to rotate one end of the guiding mechanism 4 away from the carrier belt conveyor 1 into another conveying channel 5 (the conveying channel 5 corresponding to the reel mechanism 6 that is to receive the carrier belt segment). At this time, as the carrier belt conveyor 1 conveys, the front end of the current carrier belt segment enters the other conveying channel 5, and the current carrier belt segment is gradually wound onto the reel mechanism 6 corresponding to the other conveying channel.

[0038] In this embodiment, the automatic tape-making device for crystal resonators, on the one hand, uses the cutting mechanism 2 to cut the heat-sealed carrier tape 3 into carrier tape segments. When the rear end of the previous carrier tape segment has left the guide mechanism 4 and the front end of the current carrier tape segment has entered the guide mechanism 4, the control mechanism 8 controls the guide mechanism 4 to guide the front end of the current carrier tape segment into the feeding channel 5 corresponding to the reel mechanism 6 to receive the carrier tape segment. This aims to achieve "end-to-end" connection of each carrier tape segment through precise cutting and guiding control, eliminating the need for pre-reserved gaps, thereby significantly reducing the consumption of materials such as carrier tape 3 and cover tape, and minimizing resource waste. On the other hand, multiple feeding channels 5 correspond one-to-one with multiple reel mechanisms 6, and the control mechanism 8 controls the guide mechanism 4 to guide the carrier tape segments into different feeding channels 5. This aims to achieve the goal of changing full reel mechanisms 6 without stopping the machine, thereby realizing fully automatic continuous production, reducing downtime for reel changes, and improving the overall efficiency of the equipment.

[0039] In the specific implementation process, the winding speed of the reel mechanism 6 is the same as the conveying speed of the carrier tape conveying mechanism 1, resulting in a small distance between the rear end of the previous carrier tape segment and the front end of the current carrier tape segment after the cutting mechanism 2 cuts the carrier tape 3. This leads to a short duration in which the rear end of the previous carrier tape segment has already left the guide mechanism 4, and the front end of the current carrier tape segment has already entered the guide mechanism 4, thereby increasing the detection difficulty and the risk of misjudgment for the detection mechanism 7. Therefore, in order to prolong the duration of the state where the rear end of the previous carrier tape segment has already left the guide mechanism 4, and the front end of the current carrier tape segment has already entered the guide mechanism 4, thereby reducing the detection difficulty and the risk of misjudgment for the detection mechanism 7, in this embodiment, as... Figure 1 As shown, the control mechanism 8 is also used to control the winding speed of the reel mechanism 6 to increase when the cutting mechanism 2 cuts the heat-sealed cover tape 3.

[0040] For example, during implementation, the control mechanism 8 is connected to the reel mechanism 6. When the control mechanism 8 controls the cutting mechanism 2 to cut the heat-sealed cover tape and insert the carrier tape 3 with the crystal resonator, the control mechanism 8 also generates an acceleration command, which acts on the reel mechanism 6 to increase the winding speed of the reel mechanism 6.

[0041] During operation, when the cutting mechanism 2 cuts the heat-sealed tape and the carrier tape 3 containing the crystal resonator is inserted, the winding speed of the reel mechanism 6 increases. At this time, the conveying speed of the carrier tape conveying mechanism 1 is less than the winding speed of the reel mechanism 6, which gradually increases the distance between the front end of the current carrier tape segment and the rear end of the previous carrier tape segment, extending the duration of the state where the rear end of the previous carrier tape segment has left the guide mechanism 4 and the front end of the current carrier tape segment has entered the guide mechanism 4. This is intended to reduce the detection difficulty of the detection mechanism 7 and the risk of misjudgment.

[0042] In this embodiment, as Figure 1 As shown, several conveying channels 5 are evenly arranged around the conveying axis of the carrier belt 3 on the carrier belt conveying mechanism 1; the guiding mechanism 4 includes a driving member 41 and a guide tube 42; the guide tube 42 is rotatably disposed at the discharge end of the carrier belt conveying mechanism 1; the driving member 41 is disposed at the discharge end of the carrier belt conveying mechanism 1, and the driving member 41 is connected to the guide tube 42 and the control mechanism 8; wherein, the driving member 41 is used to drive the guide tube 42 to rotate around the conveying axis of the carrier belt 3 on the carrier belt conveying mechanism 1 under the control of the control mechanism 8, so that the guide tube 42 is connected to any one of the conveying channels 5.

[0043] For example, in implementation, the aforementioned several conveying channels 5 are evenly distributed around the conveying axis of the carrier belt 3 on the carrier belt conveyor mechanism 1, and each conveying channel 5 is connected to a reel mechanism 6 on the side away from the carrier belt conveyor mechanism 1. The conveying axis of the carrier belt 3 is the axis of the carrier belt 3 in the conveying direction of the carrier belt conveyor mechanism 1 when the carrier belt conveyor mechanism 1 conveys the carrier belt 3 in a straight line. For example, when there are 3 conveying channels 5, the 3 conveying channels 5 are distributed around the conveying axis of the carrier belt 3 on the carrier belt conveyor mechanism 1, and the included angle between any two adjacent conveying channels 5 is 120°. When there are 4 conveying channels 5, the 4 conveying channels 5 are distributed around the conveying axis of the carrier belt 3 on the carrier belt conveyor mechanism 1, and the included angle between any two adjacent conveying channels 5 is 90°.

[0044] The aforementioned guiding mechanism 4 includes a guide tube 42 and a driving component 41. The guide tube 42 is a hollow tubular structure with an inner diameter larger than the width of the carrier belt 3, facilitating the smooth passage of the carrier belt segment. The guide tube 42 is rotatably mounted on the discharge end of the carrier belt conveyor 1, and the axis of the guide tube 42 near the carrier belt conveyor 1 is collinear with the conveying axis of the carrier belt 3 on the carrier belt conveyor 1. This ensures that after the carrier belt 3 enters the guide tube 42, the guide tube 42 can still rotate around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1. Furthermore, the inlet of the guide tube 42 (the end of the guide tube 42 near the carrier belt conveyor 1) corresponds to the outlet of the carrier belt conveyor 1, and the outlet of the guide tube 42 (the end of the guide tube 42 away from the carrier belt conveyor 1) is located on the circumference of the entrance to the annularly distributed conveying channels 5, and can be connected to any of the conveying channels 5.

[0045] The drive component 41 can be a servo motor, stepper motor, or rotary cylinder. The drive component 41 is mounted on the discharge end of the carrier belt conveyor 1 via screwing, snap-fit, or other methods. The output shaft of the drive component 41 is connected to the guide tube 42 via coupling, gear transmission, or belt transmission, allowing the drive component 41 to drive the guide tube 42 to rotate around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1. The drive component 41 is also electrically connected to the control mechanism 8.

[0046] During operation, when the control mechanism 8 receives a switching signal, it controls the drive component 41 to rotate the guide tube 42 around the conveying axis of the carrier belt 3 on the carrier conveyor mechanism 1, rotating it by a target rotation angle in a preset rotation direction. This allows the outlet of the guide tube 42 to connect with any one of the conveying channels 5. The preset rotation direction can be counterclockwise or clockwise. The target rotation angle is calculated based on the number of conveying channels 5. In other words, the target rotation angle is equal to the angle between two adjacent conveying channels 5.

[0047] For example, there are three material conveying channels 5, which are evenly distributed around the conveying axis of the carrier belt 3 on the carrier belt conveyor mechanism 1, that is, the included angle between any two adjacent material conveying channels 5 is 120°. In other words, the target rotation angle is 120°. The three material conveying channels 5 are labeled as material conveying channel 5A, material conveying channel 5B, and material conveying channel 5C in a clockwise direction.

[0048] Assume the first carrier belt segment is located within conveying channel 5A. When the control mechanism 8 receives a switching signal, it controls the drive component 41 to rotate the guide tube 42 120° counterclockwise (the preset rotation direction) around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 (target rotation angle). At this time, the outlet of the guide tube 42 is connected to the conveying channel 5C. The second carrier belt segment enters the conveying channel 5C. When the control mechanism 8 receives another switching signal, it controls the drive component 41 to rotate the guide tube 42 120° counterclockwise (the preset rotation direction) around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 (target rotation angle). At this time, the outlet of the guide tube 42 is connected to the conveying channel 5B. The third carrier belt segment enters the conveying channel 5B.

[0049] Assume the first carrier belt segment is located within conveying channel 5A. When the control mechanism 8 receives a switching signal, it controls the drive component 41 to rotate the guide tube 42 120° clockwise (the preset rotation direction) around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 (target rotation angle). At this time, the outlet of the guide tube 42 is connected to the conveying channel 5B. The second carrier belt segment enters the conveying channel 5B. When the control mechanism 8 receives another switching signal, it controls the drive component 41 to rotate the guide tube 42 120° clockwise (the preset rotation direction) around the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 (target rotation angle). At this time, the outlet of the guide tube 42 is connected to the conveying channel 5C. The third carrier belt segment enters the conveying channel 5C. On one hand, the control mechanism 8 controls the drive component 41 to rotate the guide tube 42 around the conveying axis of the carrier belt 3 on the carrier belt conveyor mechanism 1 by a target rotation angle in a preset rotation direction, thereby connecting the outlet of the guide tube 42 to any one of the conveying channels 5. This aims to effectively ensure that each carrier belt segment is sequentially introduced into each of the conveying channels 5. On the other hand, the number of conveying channels 5 can be increased according to the time required to replace a single reel mechanism 6. This aims to ensure that when replacing the reel mechanism 6 that first completes the winding of the carrier belt 3, the remaining reel mechanisms 6 can meet the winding needs of the carrier belt 3, thereby improving the winding efficiency of the carrier belt 3.

[0050] In a preferred embodiment, the winding speed of the reel mechanism 6 increases uniformly, and the process of obtaining the acceleration of the reel mechanism 6 includes: obtaining the first required time for the drive member 41 to drive the guide tube 42 to rotate from the current conveying channel 5 to the next conveying channel 5; calculating the maximum distance that the front section of the current carrier belt segment is allowed to enter the guide tube 42 based on the first required time and the conveying speed of the carrier belt conveying mechanism 1; calculating the second required time for the front section of the current carrier belt segment to enter the guide tube at the position corresponding to the maximum distance based on the maximum distance, the conveying speed of the carrier belt conveying mechanism 1, and the distance between the cutting position and the inlet of the guide tube 42; and calculating the acceleration of the reel mechanism 6 based on the second required time and the distance between the cutting position and the outlet of the guide tube 42.

[0051] In this embodiment, as Figure 1 As shown, the guide tube 42 gradually moves away from the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 along the conveying direction of the carrier belt conveyor 1.

[0052] For example, during implementation, the axis of the guide pipe 42 near the end of the carrier belt conveyor 1 (feed inlet) is collinear with the conveying axis of the carrier belt 3 on the carrier belt conveyor 1. This ensures that when the guide pipe 42 rotates, the feed inlet of the guide pipe 42 can be aligned with the carrier belt 3 on the carrier belt conveyor 1, thereby ensuring that the carrier belt 3 can smoothly enter the guide pipe 42. Furthermore, the guide pipe 42 gradually moves away from the conveying axis of the carrier belt 3 on the carrier belt conveyor 1 along the conveying direction of the carrier belt conveyor 1. This aims to increase the distance between the discharge outlet of the guide pipe 42 and the conveying axis of the carrier belt 3 on the carrier belt conveyor 1, thereby increasing the radius of the circumference of the annularly distributed conveying channel 5, so as to facilitate the installation of the reel mechanism 6 at the discharge end of the conveying channel 5.

[0053] To facilitate real-time detection by the testing agency 7 of the position of the rear end of the previous carrier tape segment and the front end of the current carrier tape segment, in this embodiment, the guide tube 42 is made of a transparent material.

[0054] For example, in implementation, the feed tube 42 is made of engineering plastics or composite materials with high transparency, high wear resistance, and high rigidity, such as polycarbonate (PC), acrylic resin (PMMA / acrylic), transparent modified POM, or PEEK (for high wear resistance applications). This is intended to facilitate the detection of the rear end position of the previous carrier tape segment and the front end position of the current carrier tape segment by the detection mechanism 7 located outside the feed tube 42.

[0055] In a preferred embodiment, the above-mentioned automatic crystal resonator tape-making device further includes a marking mechanism 12. The marking mechanism 12 is disposed above the carrier tape conveying mechanism 1 and is located between the crystal resonator feeding mechanism 9 and the cover tape heat sealing mechanism 10. The aim is to achieve the purpose of using the marking mechanism 12 to laser-print markings on the upper surface of the crystal resonator within the carrier tape 3 as needed, facilitating subsequent crystal resonator identification.

[0056] Example 2: This example provides an automatic tape-and-reel method for crystal resonators. This method is applicable to the apparatus described in Example 1, such as... Figure 2 As shown, the method includes the following operations:

[0057] S10. Place the crystal resonators sequentially into the receiving slots on the carrier tape;

[0058] For example, during implementation, as the carrier belt conveyor transports the carrier belt from the feed end to the discharge end of the carrier belt conveyor, when the carrier belt passes below the crystal resonator feeding mechanism, the crystal resonator feeding mechanism places the crystal resonator into the receiving groove on the carrier belt.

[0059] S20. Heat-seal the cover tape onto the upper surface of the carrier tape already inserted into the crystal resonator;

[0060] For example, during implementation, when the carrier tape containing the crystal resonator is transported by the carrier tape conveyor to the area below the cover tape heat sealing mechanism, the cover tape heat sealing mechanism heat seals the cover tape onto the upper surface of the carrier tape containing the crystal resonator.

[0061] S30. Count the number of crystal resonators that have passed through the cutting mechanism;

[0062] For example, during implementation, when the front end of the carrier tape containing the crystal resonator passes below the cutting mechanism after the heat-sealed tape has been covered, the counting mechanism begins to count the number of crystal resonators on the carrier tape that has passed the cutting mechanism.

[0063] S40. When the number of crystal resonators reaches the preset value, the carrier tape is cut to form a carrier tape segment, and the count of the number of crystal resonators passing through the cutting mechanism is restarted.

[0064] For example, during implementation, when the counted number of crystal resonators reaches a preset value, the control mechanism controls the cutting mechanism to cut the carrier tape, resulting in a carrier tape segment located on the side of the cutting mechanism away from the cover heat-sealing mechanism. At this time, the carrier tape segment continues to be wound up by the reel mechanism, and the counting mechanism recounts the number of crystal resonators on the carrier tape passing under the cutting mechanism when the leading edge of the carrier tape on the side of the cutting mechanism closest to the cover heat-sealing mechanism passes below the cutting mechanism. The carrier tape segment located on the side of the cutting mechanism away from the cover heat-sealing mechanism is recorded as the previous carrier tape segment, and the carrier tape segment located on the side of the cutting mechanism close to the cover heat-sealing mechanism is recorded as the current carrier tape segment.

[0065] S50. Real-time acquisition of the position of the front end of the current carrier tape segment and the position of the rear end of the previous carrier tape segment;

[0066] For example, during implementation, the testing agency monitors the position of the rear end of the previous carrier tape segment and the position of the front end of the current carrier tape segment in real time.

[0067] S60. When it is detected that the front end of the current carrier belt segment has reached the guide mechanism and the rear end of the previous carrier belt segment has left the guide mechanism, control the guide mechanism to move so as to guide the front end of the current carrier belt segment into the material conveying channel corresponding to the reel mechanism of the carrier belt segment to be received.

[0068] For example, during implementation, when the detection mechanism detects that the rear end of the previous carrier belt segment has left the guide mechanism and the front end of the current carrier belt segment has entered the guide mechanism, the detection mechanism generates a switching signal. Upon receiving the switching signal, the control mechanism generates a control command. The guide mechanism responds to the control command and performs corresponding actions, causing the end of the guide mechanism away from the carrier belt conveyor to rotate into another feeding channel (the feeding channel corresponding to the reel mechanism receiving the carrier belt segment). At this time, as the carrier belt conveyor moves, the front end of the current carrier belt segment enters this other feeding channel, and the current carrier belt segment is gradually wound onto the reel mechanism corresponding to this other feeding channel.

[0069] The automatic tape feeding method for crystal resonators in this embodiment involves two aspects. First, the heat-sealed carrier tape is cut into segments. When the rear end of the previous segment has left the guide mechanism and the front end of the current segment has entered the guide mechanism, the guide mechanism is controlled to guide the front end of the current segment into the feeding channel corresponding to the reel mechanism receiving the next segment. This aims to achieve precise cutting and guiding control, ensuring that each segment is connected end-to-end without leaving any gaps, thus significantly reducing material consumption of carrier tape and cover tape and minimizing resource waste. Second, multiple feeding channels correspond one-to-one with multiple reel mechanisms, and the carrier segments are guided into different feeding channels by controlling the guide mechanism. This aims to achieve the goal of changing full reels without stopping the machine, thereby realizing fully automated continuous production, reducing downtime for reel changes, and improving the overall efficiency of the equipment.

[0070] In this embodiment, the process of controlling the operation of the guiding mechanism includes:

[0071] S601. Obtain the number of material conveying channels;

[0072] For example, during implementation, the number N of material conveying channels is obtained.

[0073] S602. Determine the target rotation angle of the guiding mechanism based on the number of material conveying channels;

[0074] For example, during implementation, the target rotation angle α is calculated based on the number N of material conveying channels. Wherein, α = 360° / N.

[0075] S603. Control the guide mechanism to rotate the target rotation angle along the preset rotation direction.

[0076] For example, during implementation, when the control mechanism receives a switching signal, it controls the drive component to rotate around the conveying axis of the carrier belt on the conveyor mechanism by a target rotation angle α in a preset rotation direction, thereby connecting the outlet of the guide tube to any conveying channel. The preset rotation direction can be counterclockwise or clockwise.

[0077] For example, the number of conveying channels N is 3. These 3 conveying channels are evenly distributed around the conveying axis of the carrier belt on the conveyor mechanism, meaning that the included angle between any two adjacent conveying channels is 120°. In other words, the target rotation angle α is 120°. The 3 conveying channels are labeled as conveying channel A, conveying channel B, and conveying channel C in a clockwise direction.

[0078] Assume the first carrier belt segment is located in conveyor channel A. When the control mechanism receives a switching signal, it controls the drive mechanism to rotate the guide tube 120° counterclockwise (the preset rotation direction) around the conveyor axis of the carrier belt on the carrier belt conveyor mechanism (target rotation angle). At this time, the outlet of the guide tube is connected to conveyor channel 5C. The second carrier belt segment enters conveyor channel 5C. When the control mechanism receives another switching signal, it controls the drive mechanism to rotate the guide tube 120° counterclockwise (the preset rotation direction) around the conveyor axis of the carrier belt on the carrier belt conveyor mechanism (target rotation angle). At this time, the outlet of the guide tube is connected to conveyor channel 5B. The third carrier belt segment enters conveyor channel 5B.

[0079] Assume the first carrier belt segment is located in conveying channel A. When the control mechanism receives a switching signal, it controls the drive mechanism to rotate the guide tube 120° clockwise (the preset rotation direction) around the conveying axis of the carrier belt on the carrier belt conveyor mechanism (target rotation angle). At this time, the outlet of the guide tube is connected to conveying channel 5B. The second carrier belt segment enters conveying channel 5B. When the control mechanism receives another switching signal, it controls the drive mechanism to rotate the guide tube 120° clockwise (the preset rotation direction) around the conveying axis of the carrier belt on the carrier belt conveyor mechanism (target rotation angle). At this time, the outlet of the guide tube is connected to conveying channel 5C. The third carrier belt segment enters conveying channel 5C. On the one hand, by controlling the drive mechanism to rotate the guide tube around the conveying axis of the carrier belt on the carrier belt conveyor mechanism (target rotation angle) in the preset rotation direction, the outlet of the guide tube is connected to any conveying channel. The aim is to effectively ensure that each carrier belt segment is sequentially introduced into each material conveying channel 5.
