[0002] Semiconductors are often packaged with edging tape. The turntable of the edging tape unloading mechanism has a large diameter. The larger the diameter, the greater the inertia.

[0019] 2 limiting assembly, 21 limiting chuck, 22 limiting rod, 23 floating member, 24 limiting driving member, 25 crossbeam, 26 elastic member, 27 linear bearing, 28 guide rod;

[0022] In order to enable those skilled in the art to better understand the technical solution of the present application, the technical solution of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1 and Figure 2 As shown, the hemming belt unloading mechanism includes a turntable 1 and a limit assembly 2. When the turntable 1 rotates, the hemming belt 01 slides out of the turntable 1 to realize the unloading of the hemming belt.

[0024] The limiting assembly 2 includes a limiting chuck 21, a limiting motion unit and a limiting driving member 24. The limiting chuck 21 is fixedly connected to the turntable 1. The limiting chuck 21 is evenly distributed with slots and teeth all around. The limiting motion unit includes a limiting rod 22. The movable part of the limiting driving member 24 is connected to the limiting motion unit to drive the limiting rod 22 of the limiting motion unit to extend into and out of the slot.

[0025] When material picking is finished, the limit driving part 24 drives the limit motion unit to move, so that the limit rod 22 of the limit motion unit extends into the slot of the limit chuck 21, locking the limit chuck 21. At this time, the limit chuck 21 immediately stops rotating under the stopping action of the limit rod 22. Since the limit chuck 21 is fixedly connected to the turntable 1, the turntable 1 also stops rotating immediately. Therefore, the problem of the turntable 1 continuing to rotate after the material picking is finished, causing the excess edging tape to slip out of the turntable 1, is avoided.

[0026] When it is necessary to take the material, the limit driving member 24 drives the limit motion unit to move, so that the limit rod 22 of the limit motion unit withdraws from the clamping groove of the limit chuck 21 to achieve unlocking. At this time, the turntable 1 can rotate to discharge the material.

[0027] More specifically, the edge tape unloading mechanism may further include a bottom plate 3 supporting the turntable 1. When the turntable 1 rotates, the bottom plate 3 is fixed. In addition, the edge tape unloading mechanism may further include a pressing plate 4. The pressing plate 4 is located on the opposite side of the bottom plate 3, and the turntable 1 is located between the pressing plate 4 and the bottom plate 3.

[0028] More specifically, the limiting assembly 2 may further include a mounting seat (the two cross beams 25 in the figure are mounting seats) and an elastic member 26. The mounting seat is fixedly connected to the base plate 3. The elastic member 26 is compressed between the mounting seat and the side of the limiting motion unit away from the limiting chuck 21. The elastic member 26 applies an elastic pressure to the limiting motion unit, and the elastic pressure makes the limiting rod 22 of the limiting motion unit approach the slot. With this design, even if the power is off, the elastic force of the elastic member 26 can be used to press the limiting rod 22 into the slot of the limiting chuck 21 to achieve locking of the turntable 1.

[0029] More specifically, the limiting motion unit may further include a floating member 23, and the limiting assembly 2 may further include a guide rod 28. The floating member 23 is provided with a sleeve portion. The sleeve portion is sleeved on the outer periphery of the guide rod 28. With this design, the floating member 23 floats along the guide rod 28 under the driving action of the limiting driving member 24 and / or the elastic force of the elastic member 26, and the movement stability is good. The limiting rod 22 is fixedly connected to the floating member 23 or is integrally provided to float synchronously with the floating member 23, so as to be able to extend into or withdraw from the card slot of the limiting chuck 21.

[0030] More specifically, a linear bearing 27 may be provided between the sleeve portion of the floating member 23 and the guide rod 28 to further enhance movement stability.

[0031] More specifically, the mounting base may include two cross beams 25 arranged at intervals, and two guide rods 28 extending in the longitudinal direction are connected between the two cross beams 25. The floating member 23 spans across the two guide rods 28. A sleeve portion is provided at each end of the floating member 23, and each sleeve portion is sleeved on the outer circumference of a guide rod 28. In this design, the cross beams 25, the guide rods 28 and the floating member 23 form a frame structure, so that the overall strength of the limit assembly 2 is good and the movement stability is good.

[0032] More specifically, the elastic member 26 is located on one side of the floating member 23 ( Figure 2 One end of the elastic member 26 ( Figure 2 The left end of the elastic member 26 is in contact with a crossbeam 25 of the mounting seat, and the other end of the elastic member 26 ( Figure 2 The limit drive member 24, the limit chuck 21 and the limit rod 22 are located on the other side of the floating member 23 ( Figure 2 The movable part of the limit driving member 24 is connected to the floating member 23, and the fixed part of the limit driving member 24 is connected to another crossbeam 25 of the mounting seat. With this design, the overall structure of the limit assembly 2 is compact and occupies a small layout space.

[0033] More specifically, the limiting rod 22 is fixedly connected to the middle of the floating member 23, and the limiting chuck 21 is located inside the frame formed by the guide rod 28, the floating member 23 and the crossbeam 25. With this design, the limiting assembly 2 has a compact overall structure and occupies a small layout space.

[0034] More specifically, the elastic member 26 is sleeved on the outer circumference of the guide rod 28. With this design, the guide rod 28 can not only guide the floating member 23, but also guide the elastic member 26, which is multi-purpose and helps save space. Moreover, the elastic member 26 is more stable in deformation direction under the guidance of the guide rod 28, so it has a longer service life and is not easy to be damaged.

[0035] More specifically, the limiting assembly 2 is located at the bottom side of the bottom plate 3, and one end of the rotating shaft 1a of the rotating disk 1 passes through the bottom plate 3 and extends into the center hole of the limiting chuck 21, thereby realizing the fixed connection between the rotating disk 1 and the limiting chuck 21. This connection mode is convenient and reliable.

[0036] More specifically, the limit drive 24 is a cylinder, and a solenoid valve is provided on the gas path of the cylinder. When the power is on, the gas path of the cylinder is open, thereby driving the limit motion unit to move. When the power is off, the gas path of the cylinder is cut off. Of course, the limit drive 24 is not limited to the cylinder, for example, a motor can also be used.

[0037] The above specific examples are used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and core ideas of the present application. It should be pointed out that for ordinary technicians in this technical field, without departing from the principles of the present application, several improvements and modifications can be made to the present application, and these improvements and modifications also fall within the scope of protection of the claims of the present application.
