Description

Technical Field

[0001] The utility model relates to a tightening device for fixing a material tray and belongs to the field of material tray fixing devices. Background Art

[0002] A sensor is a detection device that can sense the information being measured and can transform the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, display, recording and control. The characteristics of sensors include: miniaturization, digitization, intelligence, multi-function, systematization and networking. It is the primary link to achieve automatic detection and automatic control. The existence and development of sensors have given objects senses such as touch, taste and smell, making objects slowly come alive. Usually, according to their basic sensing functions, they are divided into ten categories: thermal sensors, photosensitive elements, gas sensors, force sensors, magnetic sensors, humidity sensors, sound sensors, radiation sensitive elements, color sensitive elements and taste sensitive elements.

[0003] During the production process of the sensor, components need to be mounted on the substrate, wherein the incoming components are carried by a carrier tape, and the carrier tape is wound on a material tray. When the material tray is installed, the material tray is mounted on the support roller on the mounting equipment through the mounting holes provided thereon, and the material tray is fixed along the length direction of the support roller through a tightening device. When the mounting equipment absorbs the components on the carrier tape, the carrier tape on the material tray is gradually pulled out at the same time to unwind the carrier tape and rotate the material tray on the support roller. However, in the prior art, in order to facilitate the installation of the material tray on the support roller, the diameter of the mounting hole is slightly larger than the diameter of the support roller, which causes the material tray to shake along the diameter direction of the support roller during rotation, affecting the stability of the material tray and easily causing the components to fall off the carrier tape.

[0004] Therefore, a tightening device for fixing the material tray is needed to improve the stability of the material tray. Utility Model Content

[0009] Preferably, the outer wall of the rotating tube is rotatably connected to the inner wall of the connecting hole via a bearing.

[0018] Compared with the prior art, the advantages of the utility model are:

[0019] The utility model discloses a tightening device for fixing a material tray, which realizes fixing of the material tray along the diameter direction of a supporting roller by abutting the conical surface of a limit block against one end of a mounting hole on the material tray, thereby preventing the material tray from shaking during rotation and improving stability.

[0035] like Figure 1-11 As shown, a tightening device for fixing a material tray in this embodiment includes a moving component 1 and a limiting component 2, wherein the limiting component 2 is rotatably connected to the moving component 1, and the moving component 1 is used to drive the limiting component 2 to move;

[0036] The limiting component 2 includes a limiting block, which is in a truncated cone shape. A connecting hole 22 is arranged on the limiting block. The connecting hole 22 is coaxially arranged with the limiting block 21. During use, the mounting hole 4 on the material tray 3 is coaxially sleeved on the supporting roller 5. A baffle 6 is fixedly arranged at one end of the supporting roller 5. The baffle 6 is the outer wall of the mounting device. Subsequently, the moving component 1 is placed on the other end of the supporting roller 5. The moving component 1 is operated to move the limiting block 21 toward the baffle 6. At this time, the limiting block 21 is coaxially arranged with the supporting roller 5, and the small diameter end of the limiting block 21 is arranged toward the baffle 6. In addition, The diameter of the mounting hole 4 is smaller than the maximum diameter of the limit block 21 and larger than the minimum diameter of the limit block 21. As the limit block 21 moves, the small diameter end of the limit block 21 is inserted into the mounting hole 4, and the end of the mounting hole 4 away from the baffle 6 is abutted against the conical surface of the limit block 21 until the material tray 3 is fitted with the baffle 6 and the limit block 21 stops moving. In this way, through the cooperation between the limit block 21 and the mounting hole 4, not only the material tray 3 is fixed along the length direction of the support roller 5, but also the material tray 3 is fixed along the diameter direction of the support roller 5, which prevents the material tray 3 from shaking during the rotation process and improves stability.

[0037] A connecting disk 23 is coaxially fixedly disposed on the large diameter end of the limiting block 21, the diameter of the connecting disk 23 is larger than the maximum diameter of the limiting block 21, and the connecting hole 22 extends to a side of the connecting disk 23 away from the limiting block 21;

[0038] The moving assembly 1 includes a rotating tube 11, one end of which is coaxially inserted into the connecting hole 22 from the large diameter end of the limit block 21, and the rotating tube 11 is rotatably connected to the limit block 21. Specifically, the outer wall of the rotating tube 11 is rotatably connected to the inner wall of the connecting hole 22 through a bearing 12. When the material tray 3 is fixed, the rotating tube 11 is coaxially sleeved on the supporting roller 5. In fact, the outer peripheral wall of the supporting roller 5 is provided with an external thread, and the inner peripheral wall of the rotating tube 11 is provided with an internal thread. The threaded connection between the rotating tube 11 and the supporting roller 5 is realized by the internal thread and the external thread. When the rotating tube 11 is rotated, the rotating The tube 11 moves on the support roller 5 along the length direction of the support roller 5, and the movement of the rotating tube 11 drives the limit block 21 to move synchronously through the bearing 12. In addition, when the carrier tape on the material tray 3 is pulled out to realize the unwinding of the carrier tape, the material tray 3 realizes self-rotation, and the rotation of the material tray 3 drives the limit block 21 to rotate synchronously through the friction force. At this time, the limit block 21 generates relative rotation with the rotating roller through the bearing 12, which prevents the rotation of the limit block 21 from driving the rotating tube 11 to rotate synchronously and causing relative movement between the rotating tube 11 and the support roller 5, thereby preventing the limit block 21 from continuing to squeeze the material tray 3 or separating from the material tray 3 during the rotation of the material tray 3;

[0039] A rotating ring 13 is coaxially fixedly sleeved on one end of the rotating tube 11 outside the connecting hole 22. The rotating ring 13 and the rotating tube 11 are an integrally formed structure. When the rotating tube 11 needs to rotate on the supporting roller 5, the rotating ring 13 can be rotated.

[0040] The outer peripheral wall of the rotating ring 13 is provided with anti-skid patterns to prevent the rotating ring 13 from slipping when it is manually rotated;

[0041] The small-diameter end of the limit block 21 is detachably fixedly connected with an end cover 24, and a through hole 25 is provided on the end cover 24. The through hole 25 is coaxially arranged with the connection hole 22, wherein the aperture of the through hole 25 is larger than the diameter of the support roller 5. The end cover 24 is locked with the limit block 21 by a plurality of screws 26, and the end cover 24 plays a protective role to reduce impurities from entering the installation connection hole 22;

[0042] The end cover 24 is in the shape of a truncated cone, the large diameter end of the end cover 24 fits with the small diameter end of the limit block 21, and the outer peripheral wall of the end cover 24 and the outer peripheral wall of the limit block 21 are on the same conical surface;

[0043] To summarize, by abutting the conical surface of the limit block 21 against one end of the mounting hole 4 on the material tray 3, the material tray 3 is fixed along the diameter direction of the support roller 5, thereby preventing the material tray 3 from shaking during rotation and improving stability. Moreover, during the rotation of the material tray 3, relative rotation occurs between the limit block 21 and the rotating tube 11, thereby preventing the limit block 21 from continuing to squeeze the material tray 3 or separating from the material tray 3 when the material tray 3 rotates.

[0044] In addition to the above embodiments, the present invention also includes other implementation modes. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the protection scope of the claims of the present invention.
