Description

Technical Field

[0001] This utility model relates to the field of electronic component taping technology, specifically to a tape full alarm device for electronic component taping. Background Technology

[0002] In the tape taping process for electronic components, it is necessary to monitor the completion of tape unwinding on the unwinding device, the presence of insufficient tape, and the fullness of the release liner peeled from the tape surface on the winding device. Upon completion of unwinding, the tape unwinding and conveying mechanisms must be stopped promptly, a new roll of tape placed on the unwinding device, and the full-load release liner removed. A full-load alarm device can sense these tape unwinding and rewinding conditions, triggering an alarm on the corresponding equipment to remind operators to take appropriate action. However, existing full-load alarm devices often use fixed sensors for detection, which cannot be adjusted to meet the full-load alarm requirements of different types of tapes, limiting their applicability to a single type or category of tape. Utility Model Content

[0003] The purpose of this invention is to provide a full material alarm device for electronic component tape, in order to solve the problem that the sensor used for full material detection in existing full material alarm devices cannot be adjusted according to the full material alarm requirements of different types of tape, thus limiting its applicability.

[0006] An adjusting plate is provided with an adjusting groove, which moves in a vertical plane parallel to the end face of the material strip reel. A first fixing member can slide through the adjusting groove and is positioned together with the adjusting plate on the top of the upper positioning frame.

[0007] A laser sensor has its emitting end facing the limiting plate. The end of the adjusting plate is provided with an assembly hole facing the limiting plate. The laser sensor is slidably inserted through the assembly hole and positioned by a second fixing member.

[0009] The device support also includes a sealing sleeve and a lower positioning frame. The bottom of the upper positioning frame is airtightly slidably inserted into the inner cavity of the sealing sleeve. The bottom of the inner cavity forms a pressure-changing chamber. The bottom of the sealing sleeve is provided with a connection interface that connects the pressure-changing chamber and an external air pressure regulating device. The lower positioning frame is connected to the sealing sleeve.

[0010] As a further description of the above technical solution:

[0011] The adjusting groove is a waist-shaped groove.

[0012] As a further description of the above technical solution:

[0013] The adjusting plate has scale lines on the side of the adjusting groove.

[0014] As a further description of the above technical solution:

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 scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0029] Example 1:

[0030] Please see Figure 1-4 This utility model provides a technical solution: a full-material alarm device for electronic component taping tape, comprising:

[0031] The device support includes an upper positioning frame 1, a rotating shaft 2 is provided on the top of the upper positioning frame 1, a material strip reel 100 is rotatably mounted on the rotating shaft 2, and a limiting disc 200 for limiting the material strip is provided on the material strip reel 100.

[0032] An adjusting plate 3 is provided with an adjusting groove 4, which moves in a vertical plane parallel to the end face of the material strip 100. The first fixing member 5 can slide through the adjusting groove 4 and is positioned together with the adjusting plate 3 on the top of the upper positioning frame 1.

[0033] The laser sensor 6 has its emitting end facing the limiting disk 200. The end of the adjusting plate 3 is provided with an assembly hole facing the limiting disk 200. The laser sensor 6 is slidably inserted through the assembly hole and positioned by the second fixing member 7.

[0034] The adjusting groove 4 is an oblong groove. The first fixing member 5 is a bolt, which is screwed onto the screw hole of the upper positioning frame 1. The axis of the screw hole is the same as the axis of the strip reel 100. Thus, by unscrewing the first fixing member 5 outward, the adjusting plate 3 slides radially relative to the strip reel 100, thereby adjusting the distance between the laser sensor 6 and the side of the strip winding on the strip reel 100. After adjustment, the first fixing member 5 is tightened again to achieve the positioning of the adjusting plate 3 and the laser sensor 6 on it on the upper positioning frame 1. Based on the thickness of the strip rolls wound in a full-load state for different types of strips, the above-mentioned corresponding adjustments are made to adapt to the full-load alarm requirements of different strips.

[0035] The adjustment plate 3 is provided with scale lines on the side of the adjustment groove 4. Based on the full material alarm requirements of different material strips, the position of the adjustment plate 3 can be quickly and accurately adjusted with reference to the scale lines, so that the laser sensor 6 can be quickly adjusted and reach the designated position, thereby improving the convenience of the adjustment operation.

[0036] The laser sensor 6 has an external thread 12 on its outer side. The second fixing member 7 is a nut that abuts against the side of the adjusting plate 3 and is screwed onto the external thread 12. This structural design allows adjustment of the distance between the laser sensor 6 and the tape reel 100 and the limiting plate 200, preventing interference between the laser sensor 6 and different types of tape reels and ensuring the accuracy of the laser sensor 6's sensing of the tape's full-load status. In use, the second fixing member 7 is screwed outward along the external thread 12 to disengage it from the adjusting plate 3, allowing the laser sensor 6 to slide on the adjusting plate 3 to adjust its distance from the tape reel 100 and the limiting plate 200. Once the position is determined, the second fixing member 7 is screwed inward along the external thread 12 to abut against the side of the adjusting plate 3, thus completing the positioning of the laser sensor 6.

[0037] The working principle of the electronic component taping tape full material alarm device in this embodiment includes: In this embodiment, the alarm device is used to sense the material shortage state of the tape unwinding device or the full material state of the winding device when the tape unwinding device is winding up the peeled-off release film on the tape surface during the unwinding of the electronic component taping tape, so as to realize the function of associated alarm. It can also be used for full material alarm of tape unwinding and winding in other application scenarios. When the tape wound on the tape reel 100 is full, that is, when the outermost side of the tape is irradiated by the light emitted by the laser sensor 6 (the light changes from irradiating the limit plate 200 to irradiating the outermost side of the tape, forming a change in distance measurement), the laser sensor 6 senses the full material state of the tape, associates with the corresponding equipment, and issues a full material alarm to remind the operator to stop the tape feeding so that the full tape can be unwound. The aforementioned alarm device can be installed at the tape winding device or the unwinding device. Specifically, the laser sensor 6 is aligned with the innermost side of the limiting plate 200. When the tape roll on the unwinding device is fully unwound, it indicates that the tape on the other side of the winding device is full. At this time, the outermost piece of tape on the unwinding device moves to the inside of the laser sensor 6, meaning the light changes from illuminating the side of the outermost piece of tape to illuminating the limiting plate 200. This achieves the sensing of a material shortage in the unwinding device and a full material in the winding device, thus enabling a linked alarm. The laser sensor 6 is a conventional laser sensor used for distance detection, and will not be described in detail here.

[0038] Example 2:

[0039] Please see Figure 1-4 The figure shows a full-material alarm device for electronic component tape according to Embodiment 2 of this utility model. Based on the above embodiments, this embodiment further improves the following technical solution: The device support also includes a sealing sleeve 8 and a lower positioning frame 9. The bottom of the upper positioning frame 1 is airtightly slidably inserted into the inner cavity 10 of the sealing sleeve 8. The bottom of the inner cavity 10 forms a pressure-changing cavity. The bottom of the sealing sleeve 8 is provided with a docking interface 11 that connects the pressure-changing cavity and an external air pressure regulating device. The lower positioning frame 9 docks with the sealing sleeve 8 and is assembled and positioned at the tape winding and unwinding device. In use, the air pressure regulating device adjusts the air pressure in the pressure transformer chamber. The air pressure formed by the air pressure difference between the inner and outer sides of the upper positioning frame 1 is used to adjust its position on the sealing sleeve 8, thereby realizing the lifting and lowering drive of the upper positioning frame 1 and its feeding tape reel 100 to meet the laying requirements of its feeding tape roll. The position adjustment design of the above-mentioned feeding tape reel 100 can be combined with the guide roller structure in the feeding tape winding and unwinding mechanism to realize the tension of the feeding tape, so as to ensure the stability of the feeding tape winding and unwinding, as well as the stability of the device support structure and the accuracy of the full material state sensing of the laser sensor 6.

[0040] In summary, due to the adoption of the above technical solution, the electronic component tape full alarm device of this embodiment has the following advantages compared with the prior art:

[0041] This utility model discloses a full-material alarm device for electronic component taping. Through the arrangement of an upper positioning frame, an adjusting plate, a first fixing component, and a second fixing component, the device allows for radial position adjustment of the laser sensor relative to the tape reel based on the thickness of different types of tape rolls wound in a full-material state. Simultaneously, the distance between the laser sensor and the tape reel and the limiting plate can be adjusted to avoid interference between the laser sensor and different types of tape rolls, ensuring the accuracy of the laser sensor's sensing of the tape full-material state. This adapts to the full-material alarm requirements of different tapes. The design of the upper positioning frame, which is driven to extend and retract on the sealing sleeve, improves the structural stability of the device support and the accuracy of the laser sensor's sensing of the full-material state.
